Vaginal changes, sexual functioning and distress of women with locally advanced cervical cancer treated in the EMBRACE vaginal morbidity substudy.

OBJECTIVE: The EMBRACE-vaginal morbidity substudy prospectively evaluated physician-assessed vaginal changes and patient-reported-outcomes (PRO) on vaginal and sexual functioning problems and distress in the first 2-years after image-guided radio(chemo)therapy and brachytherapy for locally advanced cervical cancer. METHODS: Eligible patients had stage IB1-IIIB cervical cancer with ≤5 mm vaginal involvement. Assessment of vaginal changes was graded using CTCAE. PRO were assessed using validated Quality-of-Life and sexual questionnaires. Statistical analysis included Generalized-Linear-Mixed-Models and Spearman's rho-correlation coefficients. RESULTS: 113 eligible patients were included. Mostly mild (grade 1) vaginal changes were reported over time in about 20% (range 11-37%). At 2-years, 47% was not sexually active. Approximately 50% of the sexually active women reported any vaginal and sexual functioning problems and distress over time; more substantial vaginal and sexual problems and distress were reported by up to 14%, 20% and 8%, respectively. Physician-assessed vaginal changes and PRO sexual satisfaction differed significantly (p ≤ .05) between baseline and first follow-up, without further significant changes over time. No or only small associations between physician-assessed vaginal changes and PRO vaginal functioning problems and sexual distress were found. CONCLUSIONS: Mild vaginal changes were reported after image-guided radio(chemo)therapy and brachytherapy, potentially due to the combination of tumors with limited vaginal involvement, EMBRACE-specific treatment optimization and rehabilitation recommendations. Although vaginal and sexual functioning problems and sexual distress were frequently reported, the rate of substantial problems and distress was low. The lack of association between vaginal changes, vaginal functioning problems and sexual distress shows that sexual functioning is more complex than vaginal morbidity alone.

Pelvic floor physical therapy in patients with chronic anal fissure: long-term follow-up of a randomized controlled trial.

BACKGROUND: Chronic anal fissure is a common benign anorectal disease with a high recurrence rate. Pelvic floor physical therapy has been proven effective in the short-term management in patients with chronic anal fissure and pelvic floor dysfunction (PAF-trial). The aim of this study was to determine the outcomes of the PAF-trial and fissure recurrence in patients who completed the 2 months of pelvic floor physical therapy at 1-year follow-up. METHODS: Electromyographic registration of the pelvic floor, digital rectal examination, visual analog scales, patient-related outcome measurements, and quality of life were assessed at baseline and at 1-year after inclusion. The primary outcome was muscle tone at rest during electromyographic registration of the pelvic floor at baseline and at 1-year follow-up. Secondary outcomes contained fissure recurrence, pain ratings, pelvic floor dysfunction, complaint reduction measured with a proctology specific patient-reported outcome measurement, and quality of life. RESULTS: The treatment protocol was followed by 137 patients. Ninety-seven patients (71%) completed the 1-year follow-up, 48 women (49.5%) and 49 men (50.5%) with a mean age of 44.4 ± 11.6 years (range 19-68). In the total group of patients, mean resting electromyographic values of the pelvic floor significantly improved from baseline to follow-up at 1 year (mean estimated difference 2.20 µV; 95% CI, 1.79 to 2.61; p < 0.001). After 1 year, the fissure recurred in 15 patients (15.5%). VAS-pain significantly decreased from baseline to follow-up (mean estimated difference 4.16; 95% CI, 3.75 to 4.58; p < 0.001). Dyssynergia was found in 72.9% at baseline and decreased to 14.4% at 1-year follow-up (p < 0.001). Complaint reduction measured with the Proctoprom significantly improved from baseline to 1-year follow-up (p < 0.001). Quality of life (RAND-36) significantly improved in eight of nine domains at 1-year follow-up. No significant improvement was found in the domain vitality. CONCLUSIONS: In the PAF-trial, we demonstrated that pelvic floor physical therapy yields a significant and clinical benefit in the time course and therefore should be advocated as adjuvant conservative treatment in patients with chronic anal fissure. TRIAL REGISTRATION: The trial is registered at the Dutch Trial registry (NTR7581)  https://trialsearch.who.int.

Pelvic floor physical therapy in the treatment of chronic anal fissure (PAF trial): quality of life outcome.

BACKGROUND: Chronic anal fissure is one of the most common anorectal diseases and is associated with reduced quality of life. The aim of this study was to investigate the effects of pelvic floor physical therapy on quality of life in patients with chronic anal fissure using the Short-Form 36 Health Survey (RAND-36). METHODS: Adult patients, with chronic anal fissure and concomitant pelvic floor dysfunction, such as dyssynergia and increased pelvic floor muscle tone, were recruited at the Proctos Clinic in the Netherlands, between December 2018 and July 2021 and randomly assigned to an intervention group, receiving 8 weeks of pelvic floor physical therapy or assigned to a control group receiving postponed pelvic floor physical therapy (PAF trial). Quality of life and pain ratings were outcomes of the study and were measured at 8- and 20-week follow-up. RESULTS: One hundred patients (50 women and 50 men, median age 44.6 years [range 19-68 years]), completed the RAND-36 questionnaire and visual analog (VAS) pain scale score at admission. A significant improvement was found at 20-week follow-up in all domains of the RAND-36; physical functioning, pain, health change (p < 0.001); physical role, vitality, general health, social functioning, emotional role, mental health (p < 0.05). VAS pain was significantly reduced at 8 weeks (mean estimated difference 1.98; 95% CI 1.55-2.42, p < 0.001) and remained significant at 20-week follow-up (p < 0.001). The difference between the groups as regards change in the mean pain intensity scores at 8 weeks was 2.48 (95% CI - 3.20 to - 1.75; p < 0.001). Compared to the reference values of the general Dutch population, the patients in our study with a chronic anal fissure and pelvic floor dysfunction reported an impaired quality of life in 8 of 9 domains of the RAND-36. After treatment, significant lower scores were found in 2 out of 9 domains. CONCLUSIONS: The results of this study provide evidence that treatment by pelvic floor physical therapy improves quality of life and reduces pain, making it an important tool in management of chronic anal fissure and concomitant pelvic floor dysfunction.

An Educational Need Regarding Treatment-Related Infertility and Fertility Preservation: a National Survey Among Members of the Dutch Society for Medical Oncologists.

Cancer diagnosis and treatment may influence reproductive planning and impact fertility in patients of reproductive age. Although guidelines have been established in the past decade, education, practice, and attitudes of medical oncologists regarding fertility preservation remain undecided. A nationwide survey was performed among members of the Dutch Society for Medical Oncology. Demographics, practice, knowledge, and barriers were measured regarding information provision of fertility preservation towards cancer patients of childbearing age. From 392 members, 120 oncologists completed the questionnaire (30.6%). Majority of oncologists was convinced it is their responsibility to discuss impact of cancer treatment to fertility (93.2%), yet 68.3% discussed the subject often or always (n = 82). Oncologists employed in district general hospitals were less likely to discuss fertility (p = 0.033). On average, 44.6% of reproductive men and 28.9% of reproductive women is referred to fertility specialists. Half of the respondents declared to possess sufficient knowledge regarding fertility preservation (n = 57, 47.5%). Poor prognosis (53%), unlikely survival (43.1%), and high chances on fertility recovery (28.7%) were identified as barriers to discussing fertility preservation. Among oncologists, impact of cancer treatment on fertility is a well-accepted responsibility to counsel. Despite, self-reported knowledge regarding fertility preservation is strongly varying. In practice, fertility is discussed to some extent, influenced by several barriers and depending on prognosis and type of hospital. Patients benefit from knowledge improvement among oncology care providers concerning fertility effects of cancer treatment. Education during medical school, residency, and among practicing oncologists may raise awareness, together with enhancement of referral possibilities.

Efficacy and safety of durvalumab with olaparib in metastatic or recurrent endometrial cancer (phase II DOMEC trial).

BACKGROUND: Patients with advanced endometrial cancer have a poor prognosis, and treatment options are limited. The investigator-initiated, multicenter, phase II DOMEC trial (NCT03951415) is the first trial to report data on efficacy and safety of combined treatment with PD-L1 and PARP inhibition for advanced endometrial cancer. PATIENTS AND METHODS: Patients with metastatic or recurrent endometrial cancer were enrolled. Patients received durvalumab 1500 mg intravenously q4w and olaparib 300 mg 2dd until disease progression, unacceptable toxicity, or patient withdrawal. Patients with at least 4 weeks of treatment were evaluable for analysis. The primary endpoint was progression-free survival at 6 months. Evidence for efficacy was defined as progression-free survival at 6 months in ≥50% of patients. Secondary endpoints included safety, objective response and overall survival. RESULTS: From July 2019, through November 2020, 55 patients were enrolled. At data cut-off (September 2021), 4 of the 50 evaluable patients were still on treatment. Seventeen patients (34%) were progression-free at 6 months. Objective response rate was 16% (95% CI, 8.3 to 28.5) with 1 complete and 7 partial responses. With a median follow-up of 17.6 months, median progression-free survival was 3.4 months (95% CI, 2.8 to 6.2) and median overall survival was 8.0 months (95% CI, 7.5 to 14.3). Grade 3 treatment-related adverse events occurred in 8 patients (16%), predominantly anemia. There were no grade 4 or 5 treatment-related adverse events. CONCLUSION: The combination of durvalumab and olaparib was well tolerated, but did not meet the prespecified 50% 6-month progression-free survival in this heterogeneous patient population with advanced endometrial cancer.

Sexual and fertility-related adverse effects of medicinal treatment for cancer; a national evaluation among medical oncologists.

BACKGROUND: Anti-cancer drugs commonly adversely affect fertility and sexual function. Despite this, patients report a lack of counselling of these potential adverse effects. The aim was to determine Dutch oncologists' knowledge about the adverse effects of various cancer drugs on fertility and sexual function. METHODS: A cross-sectional survey was sent to members of the Dutch Society for Medical Oncology (n = 433). The survey questions included various cancer drugs' adverse effects on fertility, ovulation, spermatogenesis, and sexual function. RESULTS: One hundred and five of 392 oncologists responded (26.8%). Oncologists were more aware of the adverse effects on fertility compared to sexual function. Drugs that were mostly believed to negatively affect fertility were cisplatin (n = 81, 80.2%), epirubicin (n = 78, 78.0%) and cyclophosphamide (n = 80, 77.7%). Regarding sexual function, most mentioned drugs were tamoxifen (n = 67, 65.7%), GnRH-agonists (n = 64, 63.4%) and cisplatin (n = 58, 57.4%). Oncologists with expertise in urology possessed more awareness regarding sexuality-related adverse effects (cisplatin p = 0.038, etoposide p = 0.025, ifosfamide p = 0.06, vinblastine p = 0.000). CONCLUSION: Results revealed that oncologists have different beliefs about possible sexual and fertility-related adverse effects concerning medication resources and literature. Based on our results, oncologists do not possess sufficient knowledge to inform patients about sexual and fertility-related adverse effects.

Pelvic floor physical therapy in patients with chronic anal fissure: a randomized controlled trial.

BACKGROUND: A chronic anal fissure is a common, painful condition with great impact on daily life. The exact pathogenesis has not been fully elucidated and treatment varies. A large percentage of patients experience pelvic floor dysfunction (dyssynergia and increased pelvic floor muscle tone). The aim of our study was to investigate the effect of pelvic floor physical therapy in patients with chronic anal fissure. METHODS: Between December 2018 and July 2021, at the Proctos Clinic in the Netherlands, patients with chronic anal fissure and pelvic floor dysfunction were randomly assigned to an intervention group, receiving 8 weeks of pelvic floor physical therapy including electromyographic biofeedback or assigned to a control group receiving postponed pelvic floor physical therapy. The primary outcome was muscle tone at rest during electromyographic registration of the pelvic floor before and after pelvic floor physical therapy. Secondary outcomes contained healing of the fissure, pain ratings, improvement of pelvic floor function, and complaint reduction measured with a proctology-specific patient-reported outcome measurement. Endpoints were measured at 8- and 20-week follow-up. RESULTS: One hundred forty patients were included in the study, 68 men (48.6%) and 72 women (51.4%) with a mean age of 44.5 ± 11.1 (range 19-79) years. Mean resting electromyographic values of the pelvic floor in the intervention group significantly improved from pre- to post-treatment (p < 0.001) and relative to controls (mean estimated difference between groups - 1.88 µV; 95% CI, - 2.49 to - 1.27 (p < 0.001) at first follow-up and remained significant from baseline at 20-week follow-up (p < 0.001). The intervention group performed better compared to the control group on all secondary outcomes, i.e., healing of the fissure (55.7% of the patients vs 21.4% in control, pain ratings (p < 0.001), diminished dyssynergia (p < 0.001), complaint reduction (p < 0.001), and decrease of pelvic floor muscle tone (p < 0.05) at first follow-up. CONCLUSIONS: The findings of this study provide strong evidence that pelvic floor physical therapy is effective in patients with chronic anal fissure and pelvic floor dysfunction and supports its recommendation as adjuvant treatment besides regular conservative treatment.

Adjuvant chemotherapy is superior to chemoradiation after D2 surgery for gastric cancer in the per-protocol analysis of the randomized CRITICS trial.

BACKGROUND: The Intergroup 0116 and the MAGIC trials changed clinical practice for resectable gastric cancer in the Western world. In these trials, overall survival improved with post-operative chemoradiotherapy (CRT) and perioperative chemotherapy (CT). Intention-to-treat analysis in the CRITICS trial of post-operative CT or post-operative CRT did not show a survival difference. The current study reports on the per-protocol (PP) analysis of the CRITICS trial. PATIENTS AND METHODS: The CRITICS trial was a randomized, controlled trial in which 788 patients with stage Ib-Iva resectable gastric or esophagogastric adenocarcinoma were included. Before start of preoperative CT, patients from the Netherlands, Sweden and Denmark were randomly assigned to receive post-operative CT or CRT. For the current analysis, only patients who started their allocated post-operative treatment were included. Since it is uncertain that the two treatment arms are balanced in such PP analysis, adjusted proportional hazards regression analysis and inverse probability weighted analysis were used to minimize the risk of selection bias and to estimate and compare overall and event-free survival. RESULTS: Of the 788 patients, 478 started post-operative treatment according to protocol, 233 (59%) patients in the CT group and 245 (62%) patients in the CRT group. Patient and tumor characteristics between the groups before start of the post-operative treatment were not different. After a median follow-up of 6.7 years since the start of post-operative treatment, the 5-year overall survival was 57.9% (95% confidence interval: 51.4% to 64.3%) in the CT group versus 45.5% (95% confidence interval: 39.2% to 51.8%) in the CRT group (adjusted hazard ratio CRT versus CT: 1.62 (1.24-2.12), P = 0.0004). Inverse probability weighted analysis resulted in similar hazard ratios. CONCLUSION: After adjustment for all known confounding factors, the PP analysis of patients who started the allocated post-operative treatment in the CRITICS trial showed that the CT group had a significantly better 5-year overall survival than the CRT group (NCT00407186).

The BUSCOPAN study: a randomized-controlled non-inferiority trial of a continuous butylscopolamine infusion versus placebo in patients with a renal colic not responding to oral non-steroidal anti-inflammatory drugs.

PURPOSE: To investigate whether placebo is non-inferior to continuous infusion of butylscopolamine in patients with renal colic. METHODS: We conducted a placebo-controlled, multicenter, double-blind randomized clinical trial (RCT) including 128 patients with renal colic (confirmed by ultrasound or CT-scan). Patients were randomized to receive either continuous IV butylscopolamine 100 mg/24 h or placebo (saline). Primary outcome is the amount of opioid escape medication used, measured in doses administered. Secondary outcomes are pain measured on a Numeric Rating Scale (NRS), side effects, and time of drug administration. Non-inferiority was assessed using linear regression with robust standard errors, with non-inferiority limit set at 0.5 units of escape medication. RESULTS: Median number of doses of escape medication was one in both groups. The number of extra doses in the placebo group compared with the butylscopolamine group was 0.05, with a 95% robust confidence interval (CI) of 0.38-0.47. Upper limit of the CI remained below the non-inferiority limit of 0.5 (p = 0.04). No differences in secondary endpoints were seen between the groups. CONCLUSION: Placebo is non-inferior to continuous IV butylscopolamine for pain relief in patients with renal colic. Based on this study and previous evidence, there is no role for continuous butylscopolamine IV in the treatment of renal colic. Trial NL7819.

Sexual Health Needs: How Do Breast Cancer Patients and Their Partners Want Information?

It is well known that breast cancer treatment can affect sexuality. This survey evaluated the needs of breast cancer patients and partners regarding sexual care. The majority of patients (80.4%) and partners (73.7%) did not receive any information regarding sexuality. Although only a quarter of all respondents reported a direct need for information regarding sexuality, most valued an opportunity to discuss sexuality. The nurse practitioner was the most preferable care provider to provide information about sexuality, supported by a brochure or website. Patients considered during treatment as most suitable timing of discussing sexuality, and partners before the start of treatment.

Discussing sexuality in cancer care: towards personalized information for cancer patients and survivors.

INTRODUCTION: The needs of cancer patients and survivors regarding discussing sexuality are frequently unmet, with many not receiving adequate information. To optimize information about sexuality and cancer, patients' perspective is needed. The goals of this study were to investigate what kind of information Dutch cancer patients need, their ideas on how to improve communication, and to identify patients who are more in need of information regarding sexuality. METHODS: The Dutch Federation of Cancer Patient Organizations developed and conducted a nationwide 28-item online survey. The survey was distributed among cancer patients and survivors. RESULTS: In total, 2657 (ex) cancer patients participated, with a median age of 61 years, and half were male (45.2%). Of the respondents, 65% were in need of information about sexuality. Patients ≤ 61 years (p < 0.001), patients with a self-reported negative effect of cancer on sexuality (p < 0.001) and patients who were diagnosed less than 2 years ago (p < 0.04) reported a higher need for information. Regardless of type of cancer, patients were most in need of practical tips and practical information regarding sexuality. To enhance communication about sexuality, 64% of the respondents suggested that it would be of help if care providers give information as standard care. CONCLUSIONS: (Ex) cancer patient prefer to receive standard information about sexuality by their care providers. According to patients' preferences, information must include practical tips. Age, self-reported negative effect on sexuality status and time from diagnoses influenced the need for information.

Using a quality of life (QoL)-monitor: preliminary results of a randomized trial in Dutch patients with early breast cancer.

PURPOSE: The diagnosis and treatment of cancer negatively affect patients' physical, functional and psychological wellbeing. Patients' needs for care cannot be addressed unless they are recognized by healthcare providers (HCPs). The use of quality of life (QoL) assessments with feedback to HCPs might facilitate the identification and discussion of QoL-topics. METHODS: 113 patients with stage I-IIIB breast cancer treated with chemotherapy were included in this randomized controlled trial. Patients were randomly allocated to receive either usual care, or usual care with an intervention consisting of a QoL-monitor assessing QoL, distress and care needs before every chemotherapy cycle visit. Patients completed questionnaires regarding QoL, illness perceptions, self-efficacy, and satisfaction with communication. From the 2nd visit onwards, patients in the intervention arm and their HCPs received a copy of the QoL overview and results were shown in patients' medical files. Audio-recordings and patients' self-reports were used to investigate effects on communication, patient management and patient-wellbeing. A composite score for communication was calculated by summing the number of QoL-topics discussed during each consultation. RESULTS: Use of the QoL-monitor resulted in a higher communication score (0.7 topics increase per visit, p = 0.04), especially regarding the disease-specific and psychosocial issues (p < 0.01). There were no differences in patient management, QoL, illness perceptions or distress. Patients in the experimental arm (n = 60) had higher scores on satisfaction with communication (p < 0.05). CONCLUSIONS: Use of a QoL-monitor during chemotherapy in patients with early breast cancer might result in a more frequent discussion of QoL-topics, associated with high levels of patients' satisfaction.

Frequency and prognosis of associated malignancies in 504 patients with lymphomatoid papulosis.

BACKGROUND: Lymphomatoid papulosis (LyP) can be associated with other haematological malignancies (HM), but reported percentages vary from 20% to over 50%. OBJECTIVE: To evaluate the frequency and prognostic significance of associated HM and non-HM in LyP patients. METHODS: In this multicentre cohort study, the complete Dutch LyP population was included from the Dutch Cutaneous Lymphoma Registry between 1985 and 2018. Clinical and histopathological information was retrieved from every individual patient. RESULTS: After a median follow-up of 120 months (range, 6-585), an associated HM was observed in 78/504 (15.5%) patients. Most common associated HM were mycosis fungoides (MF; n = 31) and anaplastic large-cell lymphoma (ALCL; n = 29), while 19 patients had another HM of B-cell (n = 14) or myeloid origin (n = 5). Even after a 25-year follow-up period, percentages of associated HM did not exceed 20%. Thirty-nine of 465 patients (8.4%) without a prior or concurrent associated HM developed an associated HM during follow-up, after a median of 68 months (range of 3-286 months). Nine of 78 patients died of associated HM, including 6/22 patients developing extracutaneous ALCL, while all patients with associated MF or skin-limited ALCL had an excellent prognosis. Compared with the general population, LyP patients showed an increased risk (relative risk, 2.8; 95% confidence intervals, 2.4-3.3) for non-HM, in particular cutaneous squamous cell carcinoma, melanoma and intestinal/lung/bladder cancer. CONCLUSIONS: An associated HM was reported in 15.5% of the LyP patients, particularly MF and ALCL. Although the frequency of associated HM is lower than suggested and the prognosis of most patients with associated HM is excellent, a small subgroup will develop aggressive disease, in particular extracutaneous ALCL. Furthermore, LyP patients have a higher risk of developing other malignancies. Clinicians should be aware of these risks, and LyP patients require close monitoring.

Discussing Sexual Health in the Medical Oncologist's Practice: Exploring Current Practice and Challenges.

Sexuality is a significant quality-of-life concern for many cancer patients. Patients may be disadvantaged if they are not informed and not offered sexual health care. We sought to reveal oncologists' current practice and opinions concerning sexual counselling. The aim of this study was to explore the knowledge, attitude and practice patterns of Dutch medical oncologists regarding treatment-related sexual dysfunction. Questionnaires were sent to 433 members of the Dutch Society of Medical Oncology. The majority (81.5%) of the 120 responding medical oncologists (response rate 30.6%) stated they discussed sexual function with fewer than half of their patients. At the same time, 75.8% of the participating oncologists agreed that addressing sexual function is their responsibility. Sexual function was discussed more often with younger patients and patients with a curative treatment intent. Barriers for avoiding discussing sexual function were lack of time (56.1%), training (49.5%) and advanced age of the patient (50.4%). More than half (64.6%) stated they had little knowledge about the subject and the majority (72.9%) wanted to acquire additional training in sexual function counselling. Medical oncologists accept that sexual function counselling falls within their profession, yet they admit to not counselling patients routinely concerning sexual function. Only in a minority of cases do medical oncologists inform their patients about sexual side effects of treatment. Whether they counsel patients is related to how they view patient's prognosis, patient's age, and self-reported knowledge. Findings indicate there is a role for developing education and practical training.

Strong CD8+ lymphocyte infiltration in combination with expression of HLA class I is associated with better tumor control in breast cancer patients treated with neoadjuvant chemotherapy.

PURPOSE: Tumor-infiltrating lymphocytes (TILs) are associated with pathological complete response (pCR) and survival after neoadjuvant chemotherapy (NAC) in patients with early breast cancer. We investigated the prognostic and predictive role of TILs, macrophages, and HLA class 1 expression after NAC with or without the potentially immune modulating compound zoledronic acid (ZA). METHODS: Baseline tumor biopsies from 196 patients in the NEOZOTAC trial were analyzed for CD8 (cytotoxic T-cells), FoxP3 (regulatory T-cells), CD68 (macrophages), and HLA class I (HCA2/HC10) expression by immunohistochemistry and subsequently related to pCR and disease-free survival (DFS). RESULTS: A strong intratumoral CD8+ infiltration or expression of HLA class 1 by cancer cells was associated with a higher pCR rate (p < 0.05). Clinical benefit of high CD8+ T-cell infiltration was found when cancer cells expressed HLA class 1 (pCR: 21.8% vs. 6.7%, p = 0.04) but not when HLA class 1 expression was lost or downregulated (pCR: 5.9% vs. 0%, p = 0.38). Interaction analyses revealed survival benefit between HLA class 1 expression and strong CD8+ T-cell infiltration, whereas in the absence or downregulation of HLA class 1 expression, high levels of CD8+ T-cells were associated with survival disadvantage (p for interaction 0.01; hazard ratio 0.41, 95% CI 0.15-1.10, p = 0.08 and hazard ratio 7.67, 95% CI 0.88-66.4, p = 0.07, respectively). Baseline immune markers were not related to ZA treatment. CONCLUSIONS: Strong baseline tumor infiltration with CD8+ T-cells in the presence of tumoral HLA class 1 expression in patients with HER2-negative breast cancer is related to a higher pCR rate and a better DFS after NAC.

Predicting the chances of having a baby with or without treatment at different time points in couples with unexplained subfertility.

STUDY QUESTION: Can we develop a prediction model that can estimate the chances of conception leading to live birth with and without treatment at different points in time in couples with unexplained subfertility? SUMMARY ANSWER: Yes, a dynamic model was developed that predicted the probability of conceiving under expectant management and following active treatments (in vitro fertilisation (IVF), intrauterine insemination with ovarian stimulation (IUI + SO), clomiphene) at different points in time since diagnosis. WHAT IS KNOWN ALREADY: Couples with no identified cause for their subfertility continue to have a realistic chance of conceiving naturally, which makes it difficult for clinicians to decide when to intervene. Previous fertility prediction models have attempted to address this by separately estimating either the chances of natural conception or the chances of conception following certain treatments. These models only make predictions at a single point in time and are therefore inadequate for informing continued decision-making at subsequent consultations. STUDY DESIGN, SIZE, DURATION: A population-based study of 1316 couples with unexplained subfertility attending a regional clinic between 1998 and 2011. PARTICIPANTS/MATERIALS, SETTING, METHODS: A dynamic prediction model was developed that estimates the chances of conception within 6 months from the point when a diagnosis of unexplained subfertility was made. These predictions were recomputed each month to provide a dynamic assessment of the individualised chances of conception while taking account of treatment status in each month. Conception must have led to live birth and treatments included clomiphene, IUI + SO, and IVF. Predictions for natural conception were externally validated using a prospective cohort from The Netherlands. MAIN RESULTS AND THE ROLE OF CHANCE: A total of 554 (42%) couples started fertility treatment within 2 years of their first fertility consultation. The natural conception leading to live birth rate was 0.24 natural conceptions per couple per year. Active treatment had a higher chance of conception compared to those who remained under expectant management. This association ranged from weak with clomiphene to strong with IVF [clomiphene, hazard ratio (HR) = 1.42 (95% confidence interval, 1.05 to 1.91); IUI + SO, HR = 2.90 (2.06 to 4.08); IVF, HR = 5.09 (4.04 to 6.40)]. Female age and duration of subfertility were significant predictors, without clear interaction with the relative effect of treatment. LIMITATIONS, REASONS FOR CAUTION: We were unable to adjust for other potentially important predictors, e.g. measures of ovarian reserve, which were not available in the linked Grampian dataset that may have made predictions more specific. This study was conducted using single centre data meaning that it may not be generalizable to other centres. However, the model performed as well as previous models in reproductive medicine when externally validated using the Dutch cohort. WIDER IMPLICATIONS OF THE FINDINGS: For the first time, it is possible to estimate the chances of conception following expectant management and different fertility treatments over time in couples with unexplained subfertility. This information will help inform couples and their clinicians of their likely chances of success, which may help manage expectations, not only at diagnostic workup completion but also throughout their fertility journey.

Impact of resection margin status on recurrence and survival in pancreatic cancer surgery.

BACKGROUND: The prognosis of patients with pancreatic ductal adenocarcinoma (PDAC) is poor and selection of patients for surgery is challenging. This study examined the impact of a positive resection margin (R1) on locoregional recurrence (LRR) and overall survival (OS); and also aimed to identified tumour characteristics and/or technical factors associated with a positive resection margin in patients with PDAC. METHODS: Patients scheduled for pancreatic resection for PDAC between 2006 and 2016 were identified from an institutional database. The effect of resection margin status, patient characteristics and tumour characteristics on LRR, distant metastasis and OS was assessed. RESULTS: A total of 322 patients underwent pancreatectomy for PDAC. A positive resection (R1) margin was found in 129 patients (40·1 per cent); this was associated with decreased OS compared with that in patients with an R0 margin (median 15 (95 per cent c.i. 13 to 17) versus 22 months; P < 0·001). R1 status was associated with reduced time to LRR (median 16 versus 36 (not estimated, n.e.) months; P = 0·002). Disease recurrence patterns were similar in the R1 and R0 groups. Risk factors for early recurrence were tumour stage, positive lymph nodes (N1) and perineural invasion. Among 100 patients with N0 disease, R1 status was associated with shorter OS compared with R0 resection (median 17 (10 to 24) versus 45 (n.e.) months; P = 0·002), whereas R status was not related to OS in 222 patients with N1 disease (median 14 (12 to 16) versus 17 (15 to 19) months after R1 and R0 resection respectively; P = 0·068). CONCLUSION: Although pancreatic resection with a positive margin was associated with poor survival and early recurrence, particularly in patients with N1 disease, disease recurrence patterns were similar between R1 and R0 groups.

Discussing sexuality with Parkinson's disease patients: a multinational survey among neurologists.

Sexual dysfunction is a major non-motor feature of Parkinson's disease (PD) that may affect the quality of life of many patients. In a Dutch survey, we demonstrated that neurologists often fail to discuss sexuality with their patients. Our objective was to determine to which extent neurologists in Spain and Germany address sexuality with their patients and whether cross-cultural differences exist. A 30-item questionnaire was sent out to 1650 German and 460 Spanish neurologists. The questionnaire addressed attitudes, knowledge, barriers, and feelings of responsibility regarding sexuality in PD. 160 German and 32 Spanish respondents completed and returned the questionnaire. The majority of German and Spanish participants discuss sexual dysfunction 'regularly' with male patients (61.7% and 78.9%, respectively), but 'seldom' with female patients (68.8% and 78.1%, respectively). Important barriers for German and Spanish respondents to discuss sexual dysfunction were patients not expressing sexual complaints spontaneously (52.9% and 75.0%, respectively) and insufficient consultation time (32.2% and 71.9%, respectively). Sexual dysfunction in PD was considered important by 68.3% of German and 96.9% of Spanish participants. German and Spanish neurologists do not routinely discuss sexual dysfunction with their patients, although many of them consider it important to address this topic. It is unclear why this lack of discussing sexual dysfunction is especially found for female patients and whether cultural aspects are involved. We recommend a self-assessment tool for patients to track their symptoms prior to consultation visits and advocate local guidelines that formulate who is responsible for discussing sexual dysfunction.

Impact of upfront randomization for postoperative treatment on quality of surgery in the CRITICS gastric cancer trial.

BACKGROUND: Preoperative randomization for postoperative treatment might affect quality of surgery. In the CRITICS trial (ChemoRadiotherapy after Induction chemotherapy In Cancer of the Stomach), patients were randomized before treatment to receive chemotherapy prior to a D1 + gastrectomy (removal of lymph node station (LNS) 1-9 + 11), followed by either chemotherapy (CT) or chemoradiotherapy (CRT). In this analysis, the influence of upfront randomization on the quality of surgery was evaluated. METHODS: Quality of surgery was analyzed in both study arms using surgicopathological compliance (removal of ≥ 15 lymph nodes), surgical compliance (removal of the indicated LNS), and surgical contamination (removal of LNS that should be left in situ). Furthermore, the 'Maruyama Index of Unresected disease' (MI) was evaluated in both study arms, and validated with overall survival. RESULTS: Between 2007 and 2015, 788 patients with gastric cancer were included in the CRITICS study of which 636 patients were operated with curative intent. No difference was observed between the CT and CRT group regarding surgicopathological compliance (74.8% vs 70.9%, P = 0.324), surgical compliance (43.2% vs 39.2%, P = 0.381), and surgical contamination (59.4% vs 59.9%, P = 0.567). Median MI was 1 in both groups (range CT 0-88 and CRT 0-136, P = 0.700). A MI below 5 was associated with better overall survival (CT: P = 0.009 and CRT: P = 0.013). CONCLUSION: Surgical quality parameters were similar in both study arms in the CRITICS gastric cancer trial, indicating that upfront randomization for postoperative treatment had no impact on the quality of surgery. A Maruyama Index below five was associated with better overall survival.

Additional value of triple-sensor urethral catheter in demonstrating urethral pressure variations during filling cystometry.

AIMS: During filling cystometry, urethral pressure variations (UPV) can be observed. The clinical relevance and a clear definition of this phenomenon are still a matter of debate. For further research and definition of UPV, it is important to determine how this condition can best be demonstrated. The purpose of this study is to compare continuous urethral pressure measurements with a single urethral-sensor catheter and a triple urethral-sensor catheter in demonstrating UPV. METHODS: Seventy-five adult female patients requiring urodynamic investigation enrolled in this prospective study. All patients underwent two series of filling and voiding cystometry. One series was performed with a dual-air balloon sensor urodynamic catheter, the other series with a triple urethral-sensor catheter. UPV were defined as urethral pressure drop exceeding 30 cmH2O. RESULTS: The prevalence of UPV was 37.3% (28 out of 75 patients), more common than detrusor overactivity. The triple urethral-sensor catheter was more sensitive than the single urethral-sensor catheter: In eight patients UPV were demonstrated with both catheters and in 18 patients only in the measurement with the triple urethral-sensor catheter. This difference in detection was significant (P < .001). CONCLUSION: There is an additional value in measurement with the triple urethral-sensor catheter for demonstration of UPV during filling cystometry. Currently, continuous measurement of urethral pressure during filling cystometry and UPV is not defined within International Continence Society terminology. The single urethral-sensor catheter is useful for a start, however, it demonstrates less than half of all UPV.
