Cumulative pregnancy rates of two strategies: Day 3 fresh embryo transfer followed by Day 3 or Day 5/6 vitrification and embryo transfer: a randomized controlled trial.

STUDY QUESTION: Are cumulative pregnancy rates better if supernumerary embryos are vitrified on Day 5/6 instead of Day 3? SUMMARY ANSWER: The results do not show a significant difference in cumulative pregnancy rates between the Day 3 and Day 5/6 vitrification groups. WHAT IS KNOWN ALREADY: Pregnancy and live birth rates following IVF or ICSI treatment are higher after extended embryo culture and blastocyst transfer (Day 5/6) compared to cleavage-stage (Day 3) transfer. Cumulative pregnancy rates from one oocyte retrieval (OR) cycle show no significant difference after fresh and frozen embryo transfers, but only one study has used vitrification for the cryopreservation of supernumerary embryos while four studies have used a slow freezing protocol. STUDY DESIGN, SIZE, DURATION: Our prospective randomized controlled trial was performed in an academic centre between January 2018 and August 2020. Patients were randomized into vitrification Day 3 (n = 80) or Day 5/6 (n = 81) groups. The primary outcome was the cumulative ongoing pregnancy rate (cOPR), considering only the first pregnancy for each couple. The power calculation revealed that 75 patients were required in each group, when assuming a 50% cOPR with four embryo transfers in the vitrification Day 3 group vs two transfers in the vitrification Day 5/6 group. PARTICIPANTS/MATERIALS, SETTING, METHODS: Patients <38 years undergoing their first or second OR cycles were randomized at the start of the first cycle. Up to two cycles were included in the analysis. A fresh embryo transfer was performed on Day 3. Supernumerary embryos (with ≥6 cells, <25% fragmentation, and equal blastomeres) or blastocysts (with expansion grade ≥2 with inner cell mass and trophectoderm score A/B) were vitrified on Day 3 or Day 5/6, respectively, and then transferred at a later date. A time-to-event analysis was performed with the patient's first ongoing pregnancy as the event of interest and the number of embryo transfers as the time component. The statistical comparison was performed by a Cox proportional hazards model. Cumulative costs of vitrification on Day 3 vs Day 5/6 were explored and compared using Mann-Whitney U tests. MAIN RESULTS AND THE ROLE OF CHANCE: By December 2021, 233 transfers (96 fresh and 137 frozen) in 77 patients were performed in the vitrification Day 3 group and 201 transfers (88 fresh and 113 frozen) in 77 patients were performed in the vitrification Day 5/6 group. The time-to-event analysis did not show a difference between the two arms with regard to the patient's first ongoing pregnancy as the primary study outcome (hazard ratio [HR] 1.25, 95% CI 0.82; 1.92, P = 0.30). The cumulative ongoing pregnancy rate after eight transfers (from one or two ORs) was 57% in the vitrification Day 3 group vs 58% in the vitrification Day 5/6 group. The median number of embryo transfers until a pregnancy was achieved was five vs four, respectively, in the vitrification Day 3 group vs the Day 5/6 group. Similar results were found for the secondary study outcome, i.e. clinical pregnancy with foetal heart rate (HR 1.19, 95% CI 0.78; 1.80, P = 0.41). The cumulative clinical pregnancy rate (cCPR) after eight embryo transfers was 62% in the vitrification Day 3 group vs 59% in the vitrification Day 5/6 group. The median number of transfers until a pregnancy was achieved was four in both groups. The healthcare consumption pattern differed between the two groups and we observed higher costs for the vitrification Day 3 group compared to the vitrification Day 5/6 group, although these differences were not statistically significant. LIMITATIONS, REASONS FOR CAUTION: Although our power calculation revealed that only 75 patients were needed in each study group (ß = 0.87, α < 0.05), the numbers were low. Also, different numbers of single and double embryo transfers were performed between the two groups, which may have affected the results. The cost analysis was performed on a subset of the patients and is therefore exploratory. WIDER IMPLICATIONS OF THE FINDINGS: Our study shows no difference in the cumulative pregnancy rate nor costs after fresh and frozen embryo transfers of at most two sequential OR cycles between the Day 3 and Day 5/6 vitrification groups; however, obstetric and perinatal outcomes should be taken into account to determine the best strategy.

Randomized phase II BGOG/ENGOT-cx1 study of paclitaxel-carboplatin with or without nintedanib in first-line recurrent or advanced cervical cancer.

OBJECTIVE: Nintedanib is an oral tyrosine kinase inhibitor targeting, among others, vascular endothelial growth factor receptor. The aim was to establish the role of nintedanib in addition to paclitaxel and carboplatin in first-line recurrent/metastatic cervical cancer. METHODS: Double-blind phase II randomized study in patients with first-line recurrent or primary advanced (FIGO stage IVB) cervical cancer. Patients received carboplatin-paclitaxel with oral nintedanib 200 mg BID/placebo. The primary endpoint was progression-free survival (PFS) at 1.5 years and α = 0.15, ß = 80%, one sided. RESULTS: 120 patients (62 N, 58C) were randomized. Median follow-up was 35 months. Baseline characteristics were similar in both groups (total population: squamous cell carcinoma 62%, prior radiotherapy 64%, primary advanced 25%, recurrent 75%). The primary endpoint was met with a PFS at 1.5 years of 15.1% versus 12.8% in favor of the nintedanib arm (p = 0.057). Median overall survival (OS) was 21.7 and 16.4 months for N and C, respectively. Confirmed RECIST response rate was 48% for N and 39% for C. No new adverse events were noted for N. However, N was associated with numerically more serious adverse events for anemia and febrile neutropenia. Global health status during and at the end of the study was similar in both arms. CONCLUSION: The study met its primary endpoint with a prolonged PFS in the N arm. No new safety signals were observed.

Preventing taxane-related peripheral neuropathy, pain and nail toxicity: a prospective self-controlled trial comparing hilotherapy with frozen gloves in early breast cancer.

PURPOSE: The prevention of taxane-related toxicities at the extremities is highly important for patients' treatment and quality-of-life. Several studies endorse hand/foot-cooling using frozen gloves as a prophylactic intervention. Unlike frozen gloves, hilotherapy produces cooling at a constant temperature. Comparative data with frozen gloves are unavailable. METHODS: This prospective self-controlled study explores the efficacy of hilotherapy at the right hand and foot compared to frozen gloves at the left in patients with early breast cancer treated with weekly paclitaxel 80 mg/m2 or three-weekly docetaxel 75 mg/m2. Patient-reported outcomes were collected at baseline, 6, 12, 18 and 24 weeks after the start of treatment. Primary and secondary endpoints were the incidence of any-grade and ≥ grade 2 side-effects (peripheral neuropathy, pain and nail toxicities), and perceived comfort of both interventions. RESULTS: Sixty-two patients participated. The incidence of any-grade side-effects was similar on both sides, 85.5% with hilotherapy and 90.3% with frozen gloves (p = 1.000). The incidence of ≥ grade 2 side-effects at the extremities was significantly lower with hilotherapy: 43.6% compared to 61.3% with frozen gloves (p = 0.013). Perceived comfort was significantly better for hilotherapy than for frozen gloves (p < 0.0001). CONCLUSIONS: Compared to frozen gloves, continuous cooling of hands and feet using hilotherapy produces better prevention of ≥ grade 2 patient-reported side-effects at the extremities (peripheral neuropathy, pain and nail toxicities). Perceived comfort was significantly better for hilotherapy. From a clinical and patient perspective, hilotherapy is a better alternative for preventing clinically significant taxane-related side-effects.

Great expectations of IVF patients: the role of gender, dispositional optimism and shared IVF prognoses.

STUDY QUESTION: Which success rates do female and male IVF patients expect, what determines their expectations and do patients reconsider their expectations after receiving a personal IVF prognosis at the expense of anxious reactions? SUMMARY ANSWER: Female and male IVF patients have unrealistic high expectations which are positively associated with their dispositional optimism, and which are only reconsidered by patients receiving a less than average IVF prognosis, which leads to more anxious reactions in females. WHAT IS KNOWN ALREADY: Female patients undergoing IVF are known to have unrealistic expectations of the success of their own IVF cycle. The available evidence suggests women expect above average performance of their fertility clinic and (family) reproductive systems. The association of gender and personality trait dispositional optimism, with expectations of IVF success and the impact of providing couples with their IVF prognosis have not been studied previously. STUDY DESIGN, SIZE, DURATION: A total of 148 partnered individuals participated in this prospective survey at two separate points in treatment: following oocyte aspiration (T1) and embryo transfer (T2) (2019-2020, participation rate = 85%). At the time of embryo transfer, gynaecologists provided couples with their IVF prognosis, calculated with the Adapted van Loendersloot model. Women and their male partners completed questionnaires independently and immediately following oocyte aspiration and embryo transfer. PARTICIPANTS/MATERIALS, SETTING, METHODS: Dispositional optimism ('LOT-R' questionnaire) and expectations of IVF success (numerical rating scale) were assessed in eligible couples commencing a 2nd-6th IVF cycle on T1. Expectations of IVF success and anxiety ('Spielberger State-Anxiety Inventory') were (re)assessed on T2. The inter-partner correlation of expectations of IVF success was examined. Linear mixed models examined hypothesized determinants of expectations of IVF success (T1) and explored (determinants of) whether participants reconsidered their expectations after receiving their IVF prognosis (T1-T2) and whether couple's IVF prognosis was associated with anxious reactions (T2). MAIN RESULTS AND THE ROLE OF CHANCE: The mean of the IVF success rates expected by patients immediately after oocyte aspiration was 59.1% (±20.0), irrespective of gender (P = 0.077). Partners expectations of IVF success were moderately correlated (r = 0.483; P < 0.001). Expectations of IVF success were positively associated with the participant's dispositional optimism (P < 0.001) but were not associated with their partner's dispositional optimism, women's age and their previous (un)successful IVF experiences. Gynaecologists gave couples their calculated IVF prognosis ranging from 4.8% to 69.2% (mean = 30.9%) at the time of embryo transfer. Gender did not influence whether participants reconsidered their expectations after receiving their prognosis. In contrast to the subgroup (n = 78), who received at least an average IVF prognosis and that did not reconsider their expectations of IVF success, the subgroup (n = 70) receiving a below average IVF prognosis lowered their expectations of IVF success (interaction effect: P < 0.001) from 55% to 46%. A below average IVF prognosis was associated with anxious reactions in women but not in men (interaction effect: P = 0.011). LIMITATIONS, REASONS FOR CAUTION: The study design and sample size were more optimal for examining hypothesized determinants of patient's expectations of IVF success than for studying the impact of sharing prognoses with patients. Whether (reconsidering) expectations influences IVF discontinuation rates and achieved live birth rates has yet to be followed-up. WIDER IMPLICATIONS OF THE FINDINGS: Clinics are advised to offer patients the opportunity of receiving their IVF prognosis. Providing prognoses is in line with patient preferences and tempers the unrealistic high expectations of both partners in couples with a less than average prognosis. A sensitive communication style is indicated, as lower prognoses are associated with mild anxious reactions in women.

Efficacy of anti-HER2 therapy in metastatic breast cancer by discordance of HER2 expression between primary and metastatic breast cancer.

PURPOSE: In stage IV breast cancer, the efficacy of human epidermal growth factor receptor 2 (HER2) targeted therapies in cases with discordance in HER2 expression between primary and metastatic site is not well known. We studied progression free (PFS) and overall survival (OS) by HER2 concordance when treating women with taxane-trastuzumab (± pertuzumab) in first or second line and trastuzumab-emtansine (T-DM1) or capecitabine-lapatinib in later lines. PATIENTS AND METHODS: Retrospective monocentric study including all breast cancer patients receiving trastuzumab between January 2002 and September 2017 at the University Hospital in Leuven; we selected metastatic patients with an available HER2 status in primary and metastatic site. The Kaplan-Meier method was used for estimating PFS/OS and log-rank test for analyzing between group differences. A Cox model is used for testing difference between groups while correcting for Pertuzumab. Multivariable Cox regression is used to model overall survival as a function group, correcting for possible confounders. RESULTS: We included 74 patients; 46 had an unchanged HER2 status (positive/positive), 9 lost HER2 (positive/negative), while 19 acquired HER2 amplification (negative/positive). 25 out of 28 cases with a discordant HER2 status were positive for ER and/or PgR in the primary site. HER2 positive/negative cases had a significantly lower PFS for taxane-trastuzumab-(pertuzumab) (PFS = 5.5 months), compared to HER2 positive/positive (PFS 9 months, p = 0.01) and HER2 negative/positive (PFS 14 months, p = 0.01) patients. PFS for later line T-DM1 (n = 30) was significantly higher for the HER2 positive/positive group (PFS 6.0 months) than for the discordant groups HER2 negative/positive (PFS 1.0 month, p = 0.04) and HER2 positive/negative (PFS 1.5 month, p = 0.01). After correcting for possible confounders, the HER2 positive/negative group had a significantly worse OS compared to HER2 positive/positive (HR 0.19, 95% CI 0.08-0.44) and negative/positive (HR 0.15, 95% 0.06-0.38). CONCLUSION: Conversion of HER2 status was seen in 28 out of 74 cases and was mostly observed in hormone receptor-positive tumors. In contrast to patients with HER2 loss, patients with a positive conversion of HER2 status derived substantial benefit from first line treatment with taxane-trastuzumab-(pertuzumab). This study highlights the importance of re-biopsying the metastatic lesion and changing treatment according to the last HER2 result.

Adnexectomy by vaginal Natural Orifice Transluminal Endoscopic Surgery versus laparoscopy: results of a first randomised controlled trial (NOTABLE trial).

OBJECTIVE: To compare adnexectomy by vaginal Natural Orifice Transluminal Endoscopic Surgery (vNOTES) versus laparoscopy. DESIGN: Parallel group, 1:1 single-centre single-blinded randomised trial, designed as non-inferiority study with a margin of 15%. SETTING: Belgian teaching hospital. POPULATION: Non-pregnant non-virgin women with an intact uterus and without obliteration of the pouch of Douglas scheduled to undergo removal of an adnexal mass assessed to be benign on ultrasound by IOTA criteria. METHODS: Randomisation to laparoscopy (control group) or vNOTES (experimental group). Stratification according to adnexal size. Blinding of participants and outcome assessors by sham incisions. MAIN OUTCOME MEASURES: The primary outcome measure was adnexectomy by the allocated technique. Secondary outcomes included duration of surgery, pain scores and analgesics used, quality of life and adverse events. RESULTS: We randomly assigned 67 participants (34 to the vNOTES group and 33 to the laparoscopy group). The primary end point was always reached in both groups: there were no conversions. We performed a sensitivity analysis for the primary outcome, assuming one conversion in the vNOTES group and no conversions in the laparoscopy group: the one-sided 95% upper limit for the differences in proportions of conversion was estimated as 13%, which is below the predefined non-inferiority margin of 15%. The secondary outcomes demonstrated a shorter duration of surgery, lower pain scores, lower total dose of analgesics and a trend for more adverse events in the vNOTES group. CONCLUSIONS: vNOTES is non-inferior to laparoscopy for a successful adnexectomy without conversion. vNOTES allowed shorter operating times and less postoperative pain but there was a trend for more adverse events.

Short term effects of interceptive expansion treatment: a prospective study.

OBJECTIVES: This prospective cohort study investigated the short term effects of interceptive orthodontic treatment with a removable expansion plate, evaluating the changes in occlusion in all its dimensions: transversal, sagittal and vertical. SUBJECTS AND METHODS: A total of 226 patients treated with a removable expansion plate (slow maxillary expansion, SME) by orthodontic residents at the Department of Orthodontics, University Hospitals Leuven, Belgium were included. The patients had a mean age of 8.5 years at the start of the treatment. The mean treatment time was 6.9 months. Transversal measurements (intercanine and intermolar width) and occlusal characteristics (molar occlusion, overjet, overbite and functional shift) were collected before (T0) and after active treatment (T1). Statistical analysis was performed using the Wilcoxon signed rank test, Sign test and McNemar test for assessing changes between T0 and T1. Linear models were used to assess the associations between patient factors and the amount of expansion. RESULTS: A significant increase in transversal width at different occlusal landmarks was found. Correction of unilateral, bilateral and frontal crossbites was successful in 99.0%, 95.2% and 93.6% of the cases respectively. Changes in sagittal molar occlusion were significant: 64.9% (right side) and 62.6% (left side) remained stable, 28.4% (right) and 29.3% (left) improved and 6.7% (right) and 8.1% (left) deteriorated. Overbite changes were found to be statistically significant, though clinically irrelevant. Overjet changes were non-significant. CONCLUSIONS: A removable expansion plate is successful in improving the transversal dental dimensions of the maxilla. Statistically significant sagittal effects on molar occlusion were found. Long-term follow-up is needed to evaluate the long-term stability of this treatment.

Analysis of 108 patients with endometrial carcinoma using the PROMISE classification and additional genetic analyses for MMR-D.

OBJECTIVES: To apply the Proactive Molecular Risk Classifier for Endometrial Cancer (ProMisE) to a consecutive series of endometrial cancer (EC) patients diagnosed at a tertiary referral center and assign EC specimens to one of four molecular subgroups using immunohistochemistry (IHC) for p53/mismatch repair protein expression and sequencing for Polymerase Epsilon Exonuclease Domain Mutations (POLE-EDM). Mismatch Repair Deficient (MMR-D) cases were more thoroughly investigated to identify underlying somatic or germline genetic defects. METHODS: Hundred-and eight consecutive endometrial cancer patients, diagnosed between March 2017 and April 2019, were subjected to immunohistochemical and molecular analysis, according to ProMisE. IHC for p53 and the mismatch repair proteins (MLH1, PMS2, MSH6 and PMS2) was performed. All patients were also tested for POLE-EDM by Sanger sequencing. In addition, tumor and corresponding normal tissue of cases with abnormal MMR IHC were tested by PCR for microsatellite instability (MSI) (MSI analysis system, Promega). Hypermethylation of MLH1 promotor was tested with (methylation specific) multiplex ligation dependent probe amplification. MMR-D cases were subjected to germline mutation analysis of the mismatch repair genes, using next generation sequencing on MiSeq (Illumina) with the BRCA Hereditary Cancer MASTR Plus, (Multiplicom/Agilent), RNA mutation analysis and MLPA. RESULTS: FIGO classification was stage IA (n = 54), IB (n = 22) II(n = 8), III(n = 18) and IV(n = 6). Of the 33 patients with MMR-D on IHC (31%), 26 showed MLH1 promotor hypermethylation as the probable cause of MMR-D. The remaining 7 patients without MLH1 promotor hypermethylation were referred for germline analysis of Lynch syndrome. Six patients carried a pathogenic germline mutation in one of the mismatch repair genes: MSH6(n = 3), PMS2(n = 1), MLH1(n = 1) and MSH2 (n = 1). Pathogenic POLE-EDM were identified in 7 (6%) patients. Multiple molecular features (POLE-EDM + MMR-D or POLE-EDM + p53 abnormal) were observed in 4 patients (4%). A high concordance between MMR-D and microsatellite instability was observed in our cohort. In cases of a genetic defect in the MMR genes, we do note a large proportion of cases exhibiting microsatellite instability. On the contrary a hypermutation state, as seen in POLE EDM, does not result in accompanied phenotypic changes in MSI status. CONCLUSION: The ProMisE classification proved to be an efficient and easily implementable system. Future research should elucidate the precise biological and prognostic meaning of the cases with multiple molecular markers.

Clinical presentation, treatment modalities and outcome in patients with adrenocortical carcinoma: A single center experience.

Adrenocortical carcinoma is an orphan disease usually associated with a poor prognosis. Surgery is the only treatment with a curative intent, leaving systemic therapy mainly for the purpose of symptom control. First line combination chemotherapy with Etoposide, Doxorubicin, Cisplatin and Mitotane (EDP-Mitotane) is considered the standard of care, although this regimen is not associated with an overall survival benefit. Due to the rarity of the disease no standard therapy exists in the second line or when patients are intolerant to the first line treatment. Therefore, treatment of these patients is usually following a very individual path in daily practice. Our aim was to retrospectively analyze treatment of patients with adrenocortical carcinoma in our tertiary center and compare treatment outcomes with reports in the literature. Our findings reflect the daily practice in adrenocortical carcinoma treatment and showed that surgery is the mainstay of therapy, even in some cases with metastatic disease. Adjuvant therapy in adrenocortical carcinoma was initiated less frequently than suggested by current guidelines. Furthermore, most of the patients in our cohort received more than one line of chemotherapy for metastatic or inoperable disease with overall survival rates comparable to those published. In summary, our analysis stresses the importance of clinical trial activity in this rare disease in order to standardize and improve adrenocortical carcinoma therapy more profoundly.

Intra-arterial Mitomycin C infusion in a large cohort of advanced liver metastatic breast cancer patients: safety, efficacy and factors influencing survival.

PURPOSE: The aim of this study was to determine the safety and efficacy of Mitomycin C (MMC) infusion in a large cohort of advanced liver metastatic breast cancer patients (LMBC) and to determine factors influencing overall survival (OS). METHODS: We retrospectively analysed LMBC patients, treated with MMC infusion between 2000 and 2017. Hepatic response was measured with baseline CT scans and first available CT scan after MMC infusion by RECIST 1.1 criteria. Adverse events were registered by the CTCAE version 5.0. OS and hepatic progression free survival (hPFS) were evaluated using Kaplan-Meier estimates. After univariable analysis, a stepwise forward multivariable (MV) prediction analysis was developed to select independent pre-treatment factors associated with OS. RESULTS: We included 176 patients with a total of 599 MMC infusions, mostly heavily pre-treated patients with a median time from diagnosis of MBC to MMC infusion of 36.9 months. RECIST evaluation of liver lesions (n = 132) showed a partial response rate of 15%, stable disease of 43% and progressive disease in 17%. Adverse events grade 3 and 4 were reported in 17.5%. Median PFS was 5.5 months and median OS was 7.8 months. Significant independent baseline predictors of worse OS included number of prior systemic chemotherapy lines, prior liver ablation, higher liver tumour burden and elevated levels of bilirubin and ALT. CONCLUSION: MMC infusion is safe and effective in advanced LMBC patients. An increased number of prior therapies, a higher liver tumour burden and elevated levels of bilirubin and ALT were associated with a worse OS.

Comparison of brachytherapy and external beam radiotherapy boost in breast-conserving therapy: Patient-reported outcome measures and aesthetic outcome.

OBJECTIVE: This study aimed to estimate the probability of an unfavourable aesthetic outcome (AO) 2 years after breast-conserving therapy (BCT) and evaluate the possible influence of brachytherapy (BT) and external beam radiotherapy (EBRT) boost on patient-reported outcomes (PROs) and AO. PATIENTS AND METHODS: Patients treated with BCT starting April 2015 were prospectively included. Selection of the boost technique followed an in-house flowchart based on the depth of the tumour bed. An electron boost was performed for a superficial clinical target volume (maximum 28 mm under the epidermis), a BT boost was proposed in all other cases. Patients were followed-up for 2 years. AO was scored by the BCCT.core software and the patient. Further PROs were measured with the EORTC QLQ-C30, QOL-BR23 and the BIBCQ questionnaires. RESULTS: The analysis included 175 patients, 80 received a BT boost and 95 an EBRT boost. BT patients were significantly older; had a higher breast cup and band size, body mass index and surgical specimen weight of the wide excision; more seroma at baseline and less positive surgical section margins than patients in the EBRT group, and more patients drank alcohol. Cancer- and breast cancer-specific quality of life (QOL) and body image did not differ between the boost techniques over time. Although mean scores for breast symptoms and sexual enjoyment did differ significantly over time (p = 0.05 and < 0.01, respectively), the effect was due to differences before boost administration. Measured with BCCT.core, AO was unfavourable in 28% of patients 2 years after treatment (31% scored by the patient) and results were similar in the BT and EBRT groups. CONCLUSION: Using the presented flowchart (See Verhoeven et al. [16]), AO and PROs on QOL or body image up to 2 years after BCT are not influenced by the boost technique.

Hysterectomy by transvaginal natural orifice transluminal endoscopic surgery versus laparoscopy as a day-care procedure: a randomised controlled trial.

OBJECTIVE: To compare hysterectomy by transvaginal natural orifice transluminal endoscopic surgery (vNOTES) versus total laparoscopic hysterectomy (TLH) as a day-care procedure. DESIGN: Parallel group, 1:1 randomised single-centre single-blinded trial, designed as a non-inferiority study with a margin of 15%. SETTING: Belgian teaching hospital. POPULATION: Women aged 18-70 years scheduled to undergo hysterectomy for benign indications. METHODS: Randomisation to TLH (control group) or vNOTES (experimental group). Stratification according to uterine volume. Blinding of participants and outcome assessors. MAIN OUTCOME MEASURES: The primary outcome was hysterectomy by the allocated technique. We measured the proportion of women leaving within 12 hours after hysterectomy and the length of hospital stay as secondary outcomes. RESULTS: We randomly assigned 70 women to vNOTES (n = 35) or TLH (n = 35). The primary endpoint was always reached in both groups: there were no conversions. We performed a sensitivity analysis for the primary outcome, assuming one conversion in the vNOTES group and no conversions in the TLH group: the one-sided 95% upper limit for the differences in proportions of conversion was estimated as 7.5%, which is below the predefined non-inferiority margin. More women left the hospital within 12 hours after surgery after vNOTES: 77 versus 43%, difference 34% (95% CI 13-56%), P = 0.007. The hospital stay was shorter after vNOTES: 0.8 versus 1.3 days, mean difference -0.5 days, (95% CI -0.98 to -0.02), P = 0.004. CONCLUSIONS: vNOTES is non-inferior to TLH for successfully performing hysterectomy without conversion. Compared with TLH, vNOTES may allow more women to be treated in a day-care setting. TWEETABLE ABSTRACT: RCT: vNOTES is just as good as laparoscopy for successful hysterectomy without conversion but allows more day-care surgery.

PROMs following breast-conserving therapy for breast cancer: results from a prospective longitudinal monocentric study.

BACKGROUND: Treatment of breast cancer includes many options and shared decision making is becoming standard practice. Within the context of treatment individualization, the omission of radiotherapy (RT) can be considered. It is thereby of great importance to correctly foresee the side effects attributed to RT. Data from longitudinal studies with contemporary techniques however are sparse. The purpose of the present study was to evaluate patient-reported outcome measures (PROMs) and long-term aesthetic outcome (AO) related to RT in the breast-conserving therapy (BCT) setting for breast cancer over time. METHODS: Patients treated with BCT between April 2015 and April 2016 were prospectively included in the cohort. Evaluations were made at six time points: at baseline (before RT), during and at the end of RT, between 3 and 6 months, 1 year and 2 years after RT. AO was scored by the patient and by the BCCT.core software. Further PROMs were measured with the European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire QLQ-C30/-BR23 and the Body Image after Breast Cancer Questionnaire BIBCQ. Patients were evaluated over 2 years. First, we assessed the evolution in time. Second, we tested the differences in mean scale scores of the PROMs between patients with a favourable and an unfavourable AO. RESULTS: One hundred seventy-five patients were included in the analysis. At baseline, unsatisfactory levels were already present for several scales. Most unsatisfactory PROMs improved up to 1 year after RT. Complaints of fatigue increased at the start but decreased up to a lower level than that at baseline up to 1 year after RT (mean difference (MD) 7.6, - 12.3, respectively). Cognitive functioning showed a small decrease at the start with no further significant decrease (MD - 4.73, - 0.21, respectively). Breast symptoms significantly increased during RT but decreased afterwards up to 2 years after RT to lower values than those at baseline and were then considered satisfactory (MD 15.6, - 19.7, - 4.1, respectively). AO scored as PROM associated with BCCT.core and with the body image measures. CONCLUSIONS: The study suggests that quality of life and body image are temporarily impaired due to RT. Around one third of patients score their long-term AO as unfavourable. These results should be discussed with the patient and could help in the decision making of the treatment plan and in the clarification of the patient's expectations.

Breast cancer subtype and survival by parity and time since last birth.

BACKGROUND: Pregnancy affects breast cancer risk but how it affects the subtype and prognosis remain controversial. We studied the effect of parity and time since last birth on breast cancer subtype and outcome. PATIENTS AND METHODS: We conducted a retrospective multivariate cohort study including all premenopausal women with early breast cancer aged ≤ 50 years (N = 1306) at diagnosis at the University Hospitals Leuven (Jan. 2000-Dec. 2009). Primary study endpoints were the breast cancer subtype, disease-free survival, and distant disease-free survival by parity and time since last birth. Statistical methods used were baseline-category logits models and Cox proportional hazard models. Multivariable models were used to correct for possible confounders. RESULTS: Breast cancer subtypes did not differ between nulliparous (N = 266) and parous women (N = 1040) but subtypes differed significantly in parous women by time since last birth (p < 0.001). Tumors within 5 years of last birth were proportionally more likely triple negative and HER-2 like, even when corrected for age at diagnosis. After a mean follow-up period of 10 years, parous women had a better disease-free survival compared to nulliparous women (HR 0.733; CI 0.560-0.961; p = 0.025, HR 0.738; CI 0.559-0.974; p = 0.032 before and after correction for known prognostic factors, respectively). In parous women, a longer time since last birth was correlated with a longer disease-free survival compared to patients with a recent pregnancy (HR 0.976; CI 0.957-0.996; p = 0.018). However, after correction, this association completely disappeared (HR 1.010; CI 0.982-1.040; p = 0.480). CONCLUSION: We observed a better disease-free survival for parous than nulliparous women. The influence of recent birth on disease-free survival is probably due to tumor and patient characteristics, as recent birth is associated with more aggressive subtypes.

Body mass index, age at breast cancer diagnosis, and breast cancer subtype: a cross-sectional study.

PURPOSE: Evidence suggests that premenopausal obesity decreases and postmenopausal obesity increases breast cancer risk. Because it is not well known whether this is subtype dependent, we studied the association between body mass index (BMI) and age at breast cancer diagnosis, or the probability of being diagnosed with a specific breast cancer phenotype, by menopausal status. METHODS: All patients with non-metastatic operable breast cancer from the University Hospital Leuven diagnosed between January 1, 2000 and December 31, 2013 were included (n = 7020) in this cross-sectional study. Linear models and logistic regression were used for statistical analysis. Allowing correction for age-related BMI-increase, we used the age-adjusted BMI score which equals the difference between a patient's BMI score and the population-average BMI score corresponding to the patient's age category. RESULTS: The quadratic relationship between the age-adjusted BMI and age at breast cancer diagnosis (p = 0.0207) interacted with menopausal status (p < 0.0001); increased age at breast cancer diagnosis was observed with above-average BMI scores in postmenopausal women, and with below-average BMI scores in premenopausal women. BMI was linearly related to the probabilities of Luminal B and HER2-like breast cancer phenotypes, but only in postmenopausal women. The relative changes in probabilities between both these subtypes mirrored each other. CONCLUSION: BMI associates differently before and after menopause with age at breast cancer diagnosis and with the probability that breast cancer belongs to a certain phenotype. The opposite effect of increasing BMI on relative frequencies of Luminal B and HER2-like breast cancers suggests a common origin.

Correlation of Patient- and Physician-Scored Dysphagia with Videofluoroscopies in Patients Treated with Radiotherapy for Head and Neck Cancer.

The aim of this study was to investigate the correlation between patient-scored dysphagia and physician-scored dysphagia in head and neck cancer patients treated with radiotherapy. Furthermore, we wanted to compare both patient- and physician-scored dysphagia with dysphagia evaluated on swallowing videofluoroscopies. Sixty-three patients from two different centers treated with radiotherapy for head and neck cancer were evaluated in the current study. Swallowing videofluoroscopies at baseline, 6, and 12 months following radiotherapy were evaluated by 2 observers using the Penetration Aspiration Scale (PAS) and Swallowing Performance Status Scale (SPS) and correlated with patient and physician scored dysphagia. We observed a significant association between physician and patient scored dysphagia (p < 0.01), pre-treatment and post-treatment. Furthermore, the risk of observing dysphagia on videofluoroscopies increased significantly with increasing scores of both physician as well as patient scored dysphagia, and this at all assessed time-points. Patient-scored dysphagia correlates better with dysphagia evaluated by the PAS. Physician-scored dysphagia, however, correlates better with dysphagia as evaluated using the SPS. Both physician- and patient-scored dysphagia correlate well with dysphagia evaluated on videofluoroscopies. Since patient-scored dysphagia correlates better with PAS and changes in the PAS score, and physician-scored dysphagia correlates better with SPS, we advocate to use both patient- and physician-scored dysphagia in future trials.

Is colorectal surgery beyond the age of 80 still feasible with acceptable mortality? An analysis of the predictive value of CR-POSSUM and life expectancy after hospital discharge.

AIM: Increased morbidity and mortality could mitigate the positive effect of surgery in elderly patients undergoing colorectal resections. This retrospective study aims to describe early morbidity and mortality together with long-term survival in octogenarians and nonagenarians undergoing colorectal surgery. Predictors for in-hospital mortality are identified. The predictive value of CR-POSSUM is assessed. METHOD: Data on consecutive patients 80 years old or more undergoing a colorectal resection in our centre from 2004 until 2010 were analysed. RESULTS: Some 286 patients [median age 84 years; interquartile range (IQR) 81.6-86.1; 133 men, 47%] underwent a colorectal resection. Median follow-up was 32 months (IQR 14.5-51.2). Two hundred and fifty-eight patients (90%) were operated on for malignancy. Only 64 patients (22.4%) underwent a laparoscopic procedure. Overall median hospital stay was 12 days (IQR 9.0-20.0) and in-hospital mortality was 9.4%. Seventy-six per cent (n = 170) of patients could return home after discharge. The 1-year survival rate was 78.6% (95% CI 73.8-82.7). Median CR-POSSUM for in-hospital mortality was 12.6% (IQR 11.9-21.0). The concordance probability estimate was 0.668 (95% CI 0.609-0.728), reflecting a moderate predictive capacity of CR-POSSUM. Once patients had been discharged from hospital, life expectancy was similar to that of the Belgian general population. CONCLUSION: Colorectal surgery in octogenarians and nonagenarians resulted in a considerable in-hospital mortality of about 9%. One-year mortality added an additional 12%, which is in concordance with the overall life expectancy at that age.

Low-dose human menopausal gonadotrophin versus clomiphene citrate in subfertile couples treated with intrauterine insemination: a randomized controlled trial.

STUDY QUESTION: Can controlled ovarian stimulation with low-dose human menopausal gonadotrophin (hMG) improve the clinical pregnancy rate when compared with ovarian stimulation with clomiphene citrate (CC) in an intrauterine insemination (IUI) programme for subfertile couples? SUMMARY ANSWER: Ovarian stimulation with low-dose hMG is superior to CC in IUI cycles with respect to clinical pregnancy rate. WHAT IS KNOWN ALREADY: IUI after ovarian stimulation is an effective treatment for mild male subfertility, unexplained subfertility and minimal-mild endometriosis, but it is unclear which medication for ovarian stimulation is more effective. STUDY DESIGN, SIZE, DURATION: A total of 330 women scheduled for IUI during 657 cycles (September 2004-December 2011) were enrolled in an open-label randomized clinical trial to ovarian stimulation with low-dose hMG subcutaneous (n = 334, 37.5-75 IU per day) or CC per oral (n = 323, 50 mg/day from Day 3-7). Assuming a difference of 10% in 'clinical pregnancy with positive fetal heart beat', we needed 219 cycles per group (alpha-error 0.05, power 0.80). PARTICIPANTS/MATERIALS, SETTING, METHODS: We studied subfertile couples with mild male subfertility, unexplained subfertility or minimal-mild endometriosis. Further inclusion criteria were failure to conceive for ≥12 months, female age ≤42 years, at least one patent Fallopian tube and a total motility count (TMC) ≥5.0 million spermatozoa after capacitation. The primary end-point was clinical pregnancy. Analysis was by intention to treat and controlled for the presence of multiple measures, as one couple could have more randomizations in multiple cycles. Linear mixed models were used for continuous measures. For binary outcomes we estimated the relative risk using a Poisson model with log link and using generalized estimating equations. MAIN RESULTS AND THE ROLE OF CHANCE: When compared with ovarian stimulation with CC, hMG stimulation was characterized by a higher clinical pregnancy rate (hMG 48/334 (14.4%) versus CC 29/323 (9.0%), relative risk (RR) 1.6 (95% confidence interval (CI) 1.1-2.4)), higher live birth rate (hMG 46/334 (13.8%) versus CC 28/323 (8.7%), RR 1.6 (95% CI 1.0-2.4)), low and comparable multiple live birth rate (hMG 3/46 (6.5%) versus CC 1/28 (3.6%), P > 0.99), lower number of preovulatory follicles (hMG 1.2 versus CC 1.5, P < 0.001), increased endometrial thickness (hMG 8.5 mm versus CC 7.5 mm, P < 0.001), and a lower cancellation rate per started cycle (hMG 15/322 (4.7%) versus CC 46/298 (15.4%), P < 0.001). LIMITATIONS, REASONS FOR CAUTION: We randomized patients at a cycle level, and not at a strategy over multiple cycles. WIDER IMPLICATIONS OF THE FINDINGS: This study showed better reproductive outcome after ovarian stimulation with low-dose gonadotrophins. A health economic analysis of our data is planned to test the hypothesis that ovarian stimulation with low-dose hMG combined with IUI is associated with increased cost-effectiveness when compared with ovarian stimulation with CC. STUDY FUNDING/ COMPETING INTERESTS: T.M.D. and K.P. were supported by the Clinical Research Foundation of UZ Leuven, Belgium. This study was also supported by the Ferring company (Copenhagen, Denmark) which provide free medication (Menopur) required for the group of patients who were randomized in the hMG COS group. The Ferring company was not involved in the study design, data analysis, writing and submission of the paper. TRIAL REGISTRATION NUMBER: NCT01569945 (ClinicalTrials.gov).

Scoring the quality of total mesorectal excision for the prediction of cancer-specific outcome.

AIM: A three-grade system for macroscopic evaluation of the resection plane is used to describe the quality of total mesorectal excision (TME). In several studies, two of the three grades have been combined when analysing the outcome. The aim of our study was to compare the predictive value of the three-graded with that of a two-graded TME score. METHOD: The quality of TME in 1382 patients who underwent elective resection for mid or low rectal adenocarcinoma was registered by 65 hospitals in PROCARE, a Belgian multidisciplinary improvement project. Prediction of outcome based on the classic three-grade score was compared with a two-grade scoring system in which intramesorectal resection (IMR) was combined with mesorectal (MRR) or with muscularis propria resection (MPR). End-points included the local recurrence rate, distant metastasis rate (DMR), disease-free survival (DFS) and overall survival (OS). RESULTS: Among the 1382 resections, 63% were MRR, 27% IMR and 9% MPR. No significant differences were found in local recurrence between the different grades of TME. A two-grade score distinguishing MRR from the others was found to predict DMR, DFS and OS as well as the three-grade score. CONCLUSION: The discriminatory and predictive value of a two-grade score, differentiating MRR from the combined IMR and MPR, was as good as the classic three-grade score.

A prospective assessment of musculoskeletal toxicity and loss of grip strength in breast cancer patients receiving adjuvant aromatase inhibitors and tamoxifen, and relation with BMI.

Aromatase inhibitor (AI) therapy for estrogen receptor-positive breast cancer is known to induce or enhance musculoskeletal problems. We have previously reported that loss of grip strength is more pronounced in AI-users with extremes in BMI. We here report results from a larger prospective study. Postmenopausal early breast cancer patients scheduled to start AI or tamoxifen therapy were recruited. A functional assessment grip strength test was performed at baseline, 3, 6, and 12 months of therapy. BMI was assessed, and a rheumatologic questionnaire was completed at each visit. 188 patients on an AI and 104 patients on tamoxifen were enrolled. 74 % of AI-users reported new/worsened musculoskeletal complaints compared with 37 % in the tamoxifen group. This was translated in a larger grip strength decrease in patients experiencing AI-induced pain opposed to patients without new/worsened complaints (p = 0.0002). 15 % of AI-users discontinued therapy due to musculoskeletal symptoms, who were characterized by a larger grip strength reduction versus adherent patients (p = 0.0107). Young age (p = 0.0135), taxane-based chemotherapy (p = 0.0223), and baseline VAS score >4 (p = 0.0155) were predictors for AI-related musculoskeletal pain. In addition, a quadratic trend of BMI with grip strength change (p = 0.0090) and probability of discontinuation was observed (p = 0.0424). Musculoskeletal events were a substantial problem in AI-treated patients and an important reason for treatment discontinuation. The decrease in grip strength was larger in AI- than in tamoxifen-users, with a more pronounced change in symptomatic patients. The inverse relationship between BMI extremes and grip strength change was confirmed in this large group of AI-patients.
