Tailored Dose-Dense Versus Standard Adjuvant Chemotherapy for High-Risk Early Breast Cancer: End-of-Study Results of the Randomized PANTHER Trial.

Clinical trials frequently include multiple end points that mature at different times. The initial report, typically based on the primary end point, may be published when key planned co-primary or secondary analyses are not yet available. Clinical Trial Updates provide an opportunity to disseminate additional results from studies, published in JCO or elsewhere, for which the primary end point has already been reported.Although dose-dense adjuvant chemotherapy administered once every 2 weeks leads to superior outcomes compared with standard regimens once every 3 weeks, the observed improvement is largely limited to studies using the suboptimal paclitaxel schedule once every 3 weeks as control. PANTHER is an international phase III trial which compared sequential epirubicin/cyclophosphamide and docetaxel administered either once every 2 or once every 3 weeks, with tailored dosing at the dose-dense schedule according to hematologic toxicity. In this end-of-study analysis, the median follow-up was 10.3 years. Compared with standard adjuvant chemotherapy, dose-dense treatment improved breast cancer recurrence-free survival (hazard ratio [HR], 0.80 [95% CI, 0.65 to 0.98]; P = .030), event-free survival (HR, 0.78 [95% CI, 0.65 to 0.94]; P = .009), and distant disease-free survival (HR, 0.79 [95% CI, 0.64 to 0.98]; P = .030) while the improvement in overall survival was not statistically significant (HR, 0.82 [95% CI, 0.65 to 1.04]; P = .109). To our knowledge, this is the first trial that confirms the benefit of a dose-dense regimen over a control regimen containing docetaxel once every 3 weeks.

Comparison between Swedish EORTC QLQ-C30 general population norm data published in 2000 and 2019.

BACKGROUND: Normative health-related quality of life (HRQoL) data from the general population are regularly used to facilitate the interpretation of HRQoL as reported by cancer patients participating in cancer clinical trials, especially when conducting long-term follow-up studies after treatment. The aim of the present study is to compare two Swedish normative data sets, published in 2000 and 2019 respectively, and explore whether HRQoL as reported by the Swedish general population has changed over time. MATERIAL AND METHODS: 'Sample 2000' was comprised of normative data from the Swedish general population who responded to the EORTC QLQ-C30 in a Swedish mail survey in 1999 (n = 3069). 'Sample 2019' consisted of data from the Swedish general population collected as part of a European norm data study using online panels, published in 2019 (n = 1027). Data were analyzed stratified by sex and age (40-49; 50-59; 60-69; 70-79 years). RESULTS: For most of the subscales and single items, no age group differences between the two samples were found, with the exception of the oldest age group (70-79 years), where Sample 2019 generally showed better HRQoL as compared to Sample 2000. Lower (worse) levels of Global quality of life and higher (worse) levels of Dyspnoea were found in Sample 2019 for most age groups. CONCLUSION: There were no differences found between the samples for most EORTC QLQ-C30 subscales and single items, with the exception of the oldest age group of both sexes in Sample 2019 who reported better HRQoL on many variables. When deciding which normative dataset to use, the mode of data collection and age group have to be considered.

Minimally important differences for interpreting EORTC QLQ-C30 change scores over time: A synthesis across 21 clinical trials involving nine different cancer types.

INTRODUCTION: Early guidelines for minimally important differences (MIDs) for the EORTC QLQ-C30 proposed ≥10 points change as clinically meaningful for all scales. Increasing evidence that MIDs can vary by scale, direction of change, cancer type and estimation method has raised doubt about a single global standard. This paper identifies MID patterns for interpreting group-level change in EORTC QLQ-C30 scores across nine cancer types. METHODS: Data were obtained from 21 published EORTC Phase III trials that enroled 13,015 patients across nine cancer types (brain, colorectal, advanced breast, head/neck, lung, mesothelioma, melanoma, ovarian, and prostate). Anchor-based MIDs for within-group change and between-group differences in change over time were obtained via mean change method and linear regression, respectively. Separate MIDs were estimated for improvements and deteriorations. Distribution-based estimates were derived and compared with anchor-based MIDs. RESULTS: Anchor-based MIDs mostly ranged from 5 to 10 points. Differences in MIDs for improvement vs deterioration, for both within-group and between-group, were mostly within a 2-points range. Larger differences between within-group and between-group MIDs were observed for several scales in ovarian, lung and head/neck cancer. Most anchor-based MIDs ranged between 0.3 SD and 0.5 SD distribution-based estimates. CONCLUSIONS: Our results reinforce recent claims that no single MID can be applied to all EORTC QLQ-C30 scales and disease settings. MIDs varied by scale, improvement/deterioration, within/between comparisons and by cancer type. Researchers applying commonly used rules of thumb must be aware of the risk of dismissing changes that are clinically meaningful or underpowering analyses when smaller MIDs apply.

Whole-body MRI surveillance in TP53 carriers is perceived as beneficial with no increase in cancer worry regardless of previous cancer: Data from the Swedish TP53 Study.

BACKGROUND: To evaluate the psychosocial consequences of surveillance with whole-body MRI (WB-MRI) in individuals with the heritable TP53-related cancer (hTP53rc) syndrome, also known as the Li-Fraumeni syndrome, with regard to cancer worry, perceived benefits and risks to surveillance and overall health. PATIENTS AND METHODS: Since 2016, the national Swedish TP53 Study (SWEP53) has offered surveillance with WB-MRI to all individuals with hTP53rc syndrome. Seventy-five individuals have been included in the study. Sixty consecutive participants fulfilled a base-line evaluation as well as an evaluation after 1 year with structured questionnaires including the Cancer Worry Scale (CWS), perceived benefits and risks of surveillance, and the 36-item Short Form Survey (SF-36). Individuals with or without previous personal cancer diagnosis were enrolled and results at baseline and after 1 year of surveillance were compared. For SF-36, a comparison with the normal population was also made. RESULTS: Participants with previous cancer tend to worry more about cancer, but both individuals with and without cancer had a positive attitude toward surveillance with no differences regarding perceived benefits and barriers to surveillance. Participants with a previous cancer scored significantly lower on some of the SF-36 subscales, but between-group differences were found only for social functioning after 1 year. CONCLUSIONS: Surveillance with WB-MRI is feasible from a psychosocial point of view both among TP53 carriers with as well as without a previous history of cancer and does not increase cancer worry in any of the groups. PLAIN LANGUAGE SUMMARY: Individuals with heritable TP53-related cancer syndrome (also known as the Li-Fraumeni syndrome) have a high lifetime risk of developing cancer. These TP53 carriers are offered surveillance with whole-body MRI to detect cancer early. There are few reports of the psychosocial impact of surveillance. In this study, we wanted to evaluate cancer worry, benefits and barriers to participation, and perceived overall health. Our study shows no increase in cancer worry after 1 year of surveillance, regardless of previous cancer.

Clinical assessment of breast symmetry and aesthetic outcome: can 3D imaging be the gold standard?

There is a lack of an accurate standardised objective method to assess aesthetic outcome after breast surgery. In this methodological study, we investigated the intra- and inter-observer reproducibility of breast symmetry and volume assessed using three-dimensional surface imaging (3D-SI), evaluated the reproducibility depending on imaging posture, and proposed a new combined volume-shape-symmetry (VSS) parameter. Images were acquired using the VECTRA XT 3D imaging system, and analysed by two observers using VECTRA Analysis Module. Breast symmetry was measured through the root mean square distance. All women had undergone bilateral risk-reducing mastectomy and immediate breast reconstruction. The reproducibility and correlations of breast symmetry and volume measurements were compared using Bland-Altman's plots and tested with Spearman's rank correlation coefficient. 3D surface images of 58 women were analysed (348 symmetry measurements, 696 volume measurements). The intra-observer reproducibility of breast symmetry measurements was substantial-excellent, the inter-observer reproducibility was substantial, and the inter-posture reproducibility was substantial. For measurements of breast volumes, the intra-observer reproducibility was excellent, the inter-observer reproducibility was moderate-substantial, and the inter-posture reproducibility was substantial-excellent. The intra-observer reproducibility of VSS was excellent while the inter-observer reproducibility was substantial for both observers, independent of posture. There were no statistically strong correlations between breast symmetry and volume differences. The intra-observer reproducibility was found to be substantial-excellent for several 3D-SI measurements independent of imaging posture. However, the inter-observer reproducibility was lower than the intra-observer reproducibility, indicating that 3D-SI in its present form is not a great assessment for symmetry.

High levels of health-related quality of life five years after curative treatment of prostate cancer with HDR-brachytherapy and external beam radiation.

BACKGROUND AND PURPOSE: The aim of this cross-sectional study was to investigate long-term health-related quality of life (HRQoL) in men with prostate cancer treated 2002-2008 with external beam radiotherapy (EBRT) combined with high dose-rate brachytherapy (HDRBT), Cohort A, and to compare these data with age-adjusted normative data. In addition, differences in HRQoL following adjustments of the brachytherapy technique in 2001 were investigated by comparing Cohort A with men treated at the same clinic from 1998-2000, Cohort B. METHODS AND MATERIAL: Cohort A: 1495 men treated with EBRT 2 Gy to 50 Gy and 2 fractions of 10 Gy HDRBT at a single centre, 2002-2008, still alive at five years. As part of routine follow-up, the patients responded to the EORTC QLQ-C30 and PR-25 questionnaires. Cohort B: HRQoL data was retrieved from an earlier study from the original article. RESULTS: In Cohort A, 1046 (70%) men completed the questionnaires at five years, median age 66 years. In general, HRQoL mean scores were high and similar to Swedish age-matched normative data. Concerning disease-specific HRQoL, low levels of bowel and urinary problems were reported, in contrast to a substantial effect on sexual functioning. 'No' or 'A little' problems with faecal incontinence and urinary incontinence were reported by 98% and 93% of patients, respectively. The corresponding figure for sexual functioning was 39%. A difference in the frequency of nocturia in favour of Cohort A was the only statistically significant difference between Cohort A and B found in general and disease-specific HRQOL (p = 0.03), despite modifications in the brachytherapy procedure introduced in 2001. CONCLUSION: Long-term general HRQoL was rated high and comparable to an aged-matched reference population five years after treatment with combined radiotherapy. Disease-specific HRQoL was still affected, foremost in the sexual domain.

Clustering of EORTC QLQ-C30 health-related quality of life scales across several cancer types: Validation study.

INTRODUCTION: The European Organisation for Research and Treatment of Cancer Quality of Life Core Questionnaire (EORTC QLQ-C30) measures 15 health-related quality of life (HRQoL) scales relevant to the disease and treatment of patients with cancer. A study by Martinelli (2011) demonstrated that these scales could be grouped into three main clusters: physical, psychological and gastrointestinal. This study aims to validate Martinelli's findings in an independent dataset and evaluate whether these clusters are consistent across cancer types and patient characteristics. METHODS: Pre-defined criteria for successful validation were three main clusters should emerge with a minimum R-squared value of 0.51 using pooled baseline-data. A cluster analysis was performed on the 15 QLQ-C30 HRQoL-scales in the overall dataset, as well as by cancer type and selected patient characteristics to examine the robustness of the results. RESULTS: The dataset consisted of 20,066 patients pooled across 17 cancer types. Overall, three main clusters were identified (R2 = 0.61); physical-cluster included role-functioning, physical-functioning, social-functioning, fatigue, pain, and global-health status; psychological-cluster included emotional-functioning, cognitive-functioning, and insomnia; gastro-intestinal-cluster included nausea/vomiting and appetite loss. The results were consistent across different levels of disease severity, socio-demographic and clinical characteristics with minor variations by cancer type. Global-health status was found to be strongly linked to the scales included in the physical-functioning-related cluster. CONCLUSION: This study successfully validated prior findings by Martinelli (2011): the QLQ-C30 scales are interrelated and can be grouped into three main clusters. Knowing how these multidimensional HRQoL scales are related to each other can help clinicians and patients with cancer in managing symptom burden, guide policymakers in defining social-support plans and inform selection of HRQoL scales in future clinical trials.

Quality of Life in the First Year of Follow-Up in a Randomized Multicenter Trial Assessing the Role of Imaging after Radical Surgery of Stage IIB-C and III Cutaneous Melanoma (TRIM Study).

The benefit of imaging in the follow-up setting for high-risk melanoma patients is uncertain, and even less is known about the impact of intensive follow-up on the patient´s quality of life. In 2017, a Swedish prospective randomized multicenter study started, in which high-risk melanoma patients are randomly assigned 1:1 to follow-up by physical examinations +/- whole-body imaging. The first-year examinations are scheduled at 0, 6 and 12 months. The aim of this study was to investigate whether the patients´ health-related quality of life (HRQoL) and levels of anxiety and depression were affected at 1 year by imaging. Anxiety/depression and HRQoL were assessed at 0 and 12 months by the questionnaires Hospital Anxiety and Depression (HAD) scale and EORTC QLQ-C30 version 3. Expected baseline QLQ-C30 values for the patients were calculated using data from the general population. In total, 204 patients were analyzed. Mean differences in subscale scores at 1 year were not statistically significant either for HRQoL or for anxiety/depression. Baseline HRQoL did not differ from expected values in the general Swedish population. In conclusion, the patients in general coped well with the situation, and adding whole-body imaging to physical examinations did not affect the melanoma patients' HRQoL or levels of anxiety or depression.

Whole-Body MRI Surveillance-Baseline Findings in the Swedish Multicentre Hereditary TP53-Related Cancer Syndrome Study (SWEP53).

A surveillance strategy of the heritable TP53-related cancer syndrome (hTP53rc), commonly referred to as the Li-Fraumeni syndrome (LFS), is studied in a prospective observational nationwide multi-centre study in Sweden (SWEP53). The aim of this sub-study is to evaluate whole-body MRI (WB-MRI) regarding the rate of malignant, indeterminate, and benign imaging findings and the associated further workup generated by the baseline examination. Individuals with hTP53rc were enrolled in a surveillance program including annual whole-body MRI (WB-MRI), brain-MRI, and in female carriers, dedicated breast MRI. A total of 68 adults ≥18 years old have been enrolled to date. Of these, 61 fulfilled the inclusion criteria for the baseline MRI scan. In total, 42 showed a normal scan, while 19 (31%) needed further workup, of whom three individuals (3/19 = 16%) were diagnosed with asymptomatic malignant tumours (thyroid cancer, disseminated upper GI cancer, and liver metastasis from a previous breast cancer). Forty-three participants were women, of whom 21 had performed risk-reducing mastectomy prior to inclusion. The remaining were monitored with breast MRI, and no breast tumours were detected on baseline MRI. WB-MRI has the potential to identify asymptomatic tumours in individuals with hTP53rc syndrome. The challenge is to adequately and efficiently investigate all indeterminate findings. Thus, a multidisciplinary team should be considered in surveillance programs for individuals with hTP53rc syndrome.

Effect of Immediate Implant-Based Breast Reconstruction After Mastectomy With and Without Acellular Dermal Matrix Among Women With Breast Cancer: A Randomized Clinical Trial.

Importance: The use of acellular dermal matrix (ADM) in implant-based breast reconstructions (IBBRs) is established practice. Existing evidence validating ADMs proposed advantages, including improved cosmetics and more single-stage IBBRs, is lacking. Objective: To evaluate whether IBBR with ADM results in fewer reoperations and increased health-related quality of life (HRQoL) compared with conventional IBBR without ADM. Design, Setting, and Participants: This was an open-label, multicenter, randomized clinical trial of women with primary breast cancer who planned for mastectomy and immediate IBBR, with a 2-year follow-up for all participants. Participants were enrolled at 5 breast cancer units in Sweden and the United Kingdom between 2014 and May 2017. Exclusion criteria included previous radiotherapy and neo-adjuvant chemotherapy. Data were analyzed until August 2017. Interventions: Participants were allocated to immediate IBBR with or without ADM. Main Outcomes and Measures: The primary trial end point was number of reoperations at 2 years. HRQoL, a secondary end point, was measured as patient-reported outcome measures using 3 instruments from the European Organization for Research and Treatment of Cancer Quality of life Questionnaire. Results: From start of enrollment on April 24, 2014, to close of trial on May 10, 2017, a total of 135 women were enrolled (mean [SD] age, 50.4 [9.5] years); 64 were assigned to have an IBBR procedure with ADM and 65 to the control group who had IBBR without ADM. There was no statistically significant difference between groups for the primary outcome. Of 129 patients analyzed at 2-year follow-up, 44 of 64 (69%) had at least 1 surgical event in the ADM group vs 43 of 65 (66%) in the control group. In the ADM group, 31 patients (48%) had at least 1 reoperation on the ipsilateral side vs 35 (54%) in the control group. The overall number of reoperations on the ipsilateral side were 42 and 43 respectively. Within the follow-up time of 24 months, 9 patients (14%) in the ADM group had the implant removed compared with 7 (11%) in the control group. We found no significant mean differences in postoperative patient-reported HRQoL domains, including perception of body image (mean difference, 3; 99% CI, -11 to 17; P = .57) and satisfaction with cosmetic outcome (mean difference, 8; 99% CI, -6 to 20; P = .11). Conclusions and Relevance: Immediate IBBR with ADM did not yield fewer reoperations compared with conventional IBBR without ADM, nor was IBBR with ADM superior in terms of HRQoL or patient-reported cosmetic outcomes. Patients treated for breast cancer contemplating ADM-supported IBBR should be informed about the lack of evidence validating ADM's suggested benefits.

High rate of local control and cure at 10 years after treatment of prostate cancer with external beam radiotherapy and high-dose-rate brachytherapy: a single centre experience.

BACKGROUND AND PURPOSE: To analyse the cumulative incidence of any failure (AF), prostate cancer-specific failure (PCSF), any death (AD), prostate cancer-specific death (PCSD), and local control in 2387 men with prostate cancer (PC), consecutively treated with combined high-dose-rate brachytherapy (HDRBT) and external beam radiotherapy (EBRT) from 1998 to 2010. MATERIAL AND METHODS: A retrospective, single-institution study of men with localised PC. The mean age was 66 years and 54.7% had high-risk PC according to the Cambridge prognostic group (CPG) classification. The treatment was delivered as EBRT (2 Gy × 25) and HDRBT (10 Gy × 2) with combined androgen blockade (CAB). The median follow-up was 10.2 years. RESULTS: The cumulative incidence of PCSD at 10 years was 5% [CI 95% 0.04-0.06]. The 10 years PCSD per risk group were: low (L) 0.4%, intermediate favourable (IF) 1%, intermediate unfavourable (IU) 4.3%, high-risk favourable (HF) 5.8%, and high-risk unfavourable (HU) 13.9%. The PCSF rate at 10 years was 16.5% [CI 95% 0.15-0.18]. The PCSF per risk group at 10 years were: L 2.5%, IF 5.5%, IU 15.9%, HF 15.6%, and HU 38.99%. PCSF occurred in 399 men, of whom 15% were found to have local failure. The estimated frequency of local failure in the entire cohort was 1.2%. CONCLUSIONS: HDRBT combined with EBRT is an effective treatment with long-term overall survival and excellent local control for patients with PC. The low rate of local recurrence among men with relapse suggests that these patients were micro metastasised at time of treatment, which calls for improved methods to detect disseminated disease.

The STHLM3-model, Risk-based Prostate Cancer Testing Identifies Men at High Risk Without Inducing Negative Psychosocial Effects.

BACKGROUND: The new STHLM3 test, combining protein markers, genetic markers, and clinical data to assess a man's prostate cancer (PCa) risk, has been investigated in Sweden within the frame of the STHLM3 trial. OBJECTIVE: To assess whether the STHLM3 test influences men's worry level, PCa knowledge, attitude, and health-related quality of life (HRQoL). DESIGN SETTING AND PARTICIPANTS: Invitations with login to the web survey were mailed to 10 000 men, 50-69 yr of age, who were eligible for the STHLM3 trial. The survey was sent 3 mo before invitation to the STHLM3 trial (baseline) and 5 mo after STHLM3 (follow-up). At baseline, the men were unaware of the upcoming invitation to STHLM3. The survey covered the following: PCa-specific worry and perceived vulnerability, knowledge about PCa, attitude toward PCa testing and health behavior, and HRQoL. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Survey scores were compared between baseline and follow-up by using the nonparametric Wilcoxon-signed rank tests for paired samples. Analysis of covariance was performed for PCa risk group comparisons. RESULTS AND LIMITATIONS: A total of 994 men (10%) responded to our survey at baseline and follow-up, and were assessed as follows: low risk: 421 men; intermediate risk: 421 men; and high risk:152, of whom 59 were diagnosed with PCa after further investigation. In men assessed as having low and intermediate risk, level of worrying decreased at follow-up (p < 0.001), whereas no changes were observed in men at high risk. Moreover, no HRQoL changes were observed over time. The low response rate is the main limitation. CONCLUSIONS: We found that the STHLM3 model, a risk-based PCa test, showed no negative impact on the well-being of men. PATIENT SUMMARY: Since our results suggest that the risk-based screening as used in STHLM3 did not induce negative psychological effects on the participants, we can recommend this risk-based approach for population-based prostate cancer screening.

Neoadjuvant Trastuzumab, Pertuzumab, and Docetaxel vs Trastuzumab Emtansine in Patients With ERBB2-Positive Breast Cancer: A Phase 2 Randomized Clinical Trial.

Importance: Trastuzumab emtansine (T-DM1) is presently approved for treatment of advanced breast cancer and after incomplete response to neoadjuvant therapy, but the potential of T-DM1 as monotherapy is so far unknown. Objective: To assess pathologic complete response (pCR) to standard neoadjuvant therapy of combination docetaxel, trastuzumab, and pertuzumab (DTP) vs T-DM1 monotherapy in patients with ERBB2 (formerly HER2)-positive breast cancer. Design, Setting, and Participants: This randomized phase 2 trial, conducted at 9 sites in Sweden, enrolled 202 patients between December 1, 2014, and October 31, 2018. Participants were 18 years or older, with ERBB2-positive tumors larger than 20 mm and/or verified lymph node metastases. Analysis was performed on an intention-to-treat basis. Interventions: Patients were randomized to receive 6 cycles of DTP (standard group) or T-DM1 (investigational group). Crossover was recommended at lack of response or occurrence of intolerable toxic effects. Assessment with fluorine 18-labeled fluorodeoxyglucose (18F-FDG) positron emission tomography combined with computed tomography (PET-CT) was performed at baseline and after 2 and 6 treatment cycles. Main Outcome and Measures: Pathologic complete response, defined as ypT0 or Tis ypN0. Secondary end points were clinical and radiologic objective response; event-free survival, invasive disease-free survival, distant disease-free survival, and overall survival; safety; health-related quality of life (HRQoL); functional and biological tumor characteristics; and frequency of breast-conserving surgery. Results: Overall, 202 patients were randomized; 197 (99 women in the standard group [median age, 51 years (range, 26-73 years)] and 98 women in the investigational group [median age, 53 years (range, 28-74 years)]) were evaluable for the primary end point. Pathologic complete response was achieved in 45 patients in the standard group (45.5%; 95% CI 35.4%-55.8%) and 43 patients in the investigational group (43.9%; 95% CI 33.9%-54.3%). The difference was not statistically significant (P = .82). In a subgroup analysis, the pCR rate was higher in hormone receptor-negative tumors than in hormone receptor-positive tumors in both treatment groups (45 of 72 [62.5%] vs 45 of 125 [36.0%]). Three patients in the T-DM1 group experienced progression during therapy. In an exploratory analysis, tumor-infiltrating lymphocytes at 10% or more (median) estimated pCR significantly (odds ratio, 2.76; 95% CI, 1.42-5.36; P = .003). Response evaluation with 18F-FDG PET-CT revealed a relative decrease of maximum standardized uptake value by equal to or greater than 68.7% (median) was associated with pCR (odds ratio, 6.74, 95% CI, 2.75-16.51; P < .001). Conclusions and Relevance: In this study, treatment with standard neoadjuvant combination DTP was equal to T-DM1. Trial Registrations: ClinicalTrials.gov Identifier: NCT02568839; EudraCT number: 2014-000808-10.

Patient-reported Outcomes and 3-dimensional Surface Imaging after Risk-reducing Mastectomy and Immediate Breast Reconstruction.

The cosmetic results after risk-reducing mastectomy (RRM) and immediate breast reconstruction (IBR) are intended to be long-lasting. Long-term follow-up of the cosmetic outcome can be evaluated subjectively by the women themselves through patient-reported outcome measures such as questionnaires, or by using data from three-dimensional surface imaging (3D-SI) to calculate the volume, shape, and symmetry of the reconstructed breasts as a more objective cosmetic evaluation. The study aim was to evaluate the correspondence between patient-reported measures and 3D-SI measurements. METHODS: Questionnaires (EORTC QLQ-BRECON23 and BIS) were sent to women on average 13 [7-20] years after RRM and IBR. Items were preselected for comparison with 3D measurements of women imaged using the VECTRA XT 3D-imaging system at the long-term follow-up. RESULTS: Questionnaire responses and 3D images of 58 women, 36 without and 22 with previous breast cancer (where 15 also received radiotherapy) before RRM and IBR, were analyzed. Median age at follow-up was 57 [41-73] years. Patient-reported satisfaction with the cosmetic outcome was positive for both groups. 3D measurements indicated more symmetrical cosmetic results for women without previous breast cancer. No statistically significant associations between patient-reported satisfaction and 3D measurements were found. CONCLUSIONS: Satisfaction with the long-term cosmetic outcome after RRM and IBR was, in general, positive when evaluated by the women. 3D-SI could be used as a more objective approach to assess the cosmetic outcome in terms of volume and shape-symmetry; however, it does not directly translate to the patient-reported satisfaction.

Radiotherapy regimens for rectal cancer: long-term outcomes and health-related quality of life in the Stockholm III trial.

BACKGROUND: The Stockholm III trial randomly assigned 840 patients to short-course radiotherapy of 5 × 5 Gy with surgery within 1 week (SRT), short-course radiotherapy of 5 × 5 Gy with surgery after 4-8 weeks (SRT-delay), or long-course radiotherapy of 25 × 2 Gy with surgery after 4-8 weeks (LRT-delay). This study details the long-term oncological outcomes and health-related quality of life (HRQoL). METHODS: Patients with biopsy-proven resectable adenocarcinoma of the rectum were included. Primary outcome was time to local recurrence (LR), and secondary endpoints were distant metastases (DMs), overall survival (OS), recurrence-free survival (RFS), and HRQoL. Patients were analysed in a three-arm randomization and a short-course radiotherapy comparison. RESULTS: From 1998 to 2013, 357, 355, and 128 patients were randomized to the SRT, SRT-delay, and LRT-delay groups respectively. Median follow-up time was 5.7 (range 5.3-7.6) years. Comparing patients in the three-arm randomization, the incidence of LR was three of 129 patients, four of 128, and seven of 128, and DM 31 of 129 patients, 38 of 128, and 38 of 128 in the SRT, SRT-delay, and LRT-delay groups respectively. In the short-course radiotherapy comparison, the incidence of LR was 11 of 357 patients and 13 of 355, and DM 88 of 357 patients and 82 of 355 in the SRT and SRT-delay groups respectively. No comparisons showed statistically significant differences. Median OS was 8.1 (range 6.9-11.2), 10.3 (range 8.2-12.8), and 10.5 (range 7.0-11.3) years after SRT, SRT-delay, and LRT-delay respectively. Median OS was 8.1 (range 7.2-10.0) years after SRT and 10.2 (range 8.5-11.7) years after SRT-delay. There were no statistically significant differences in HRQoL. CONCLUSION: After a follow-up of 5 years, delaying surgery for 4-8 weeks after radiotherapy treatment with 5 × 5 Gy was oncologically safe. Long-term HRQoL was similar among the treatment arms. TRIAL REGISTRATION NUMBER: NTC00904813.

TRIM study protocol - a prospective randomized multicenter Trial to assess the Role of Imaging during follow-up after radical surgery of stage IIB-C and III cutaneous malignant Melanoma.

BACKGROUND: The incidence of cutaneous malignant melanoma (CMM) is increasing worldwide. In Sweden, over 4600 cases were diagnosed in 2018. The prognosis after radical surgery varies considerably with tumor stage. In recent years, new treatment options have become available for metastatic CMM. Early onset of treatment seems to improve outcome, which suggests that early detection of recurrent disease should be beneficial. Consequently, in several countries imaging is a part of the routine follow-up program after surgery of high risk CMM. However, imaging has drawbacks, including resources required (costs, personnel, equipment) and the radiation exposure. Furthermore, many patients experience anxiety in waiting for the imaging results and investigations of irrelevant findings is another factor that also could cause worry and lead to decreased quality of life. Hence, the impact of imaging in this setting is important to address and no randomized study has previously been conducted. The Swedish national guidelines stipulate follow-up for 3 years by clinical examinations only. METHODS: The TRIM study is a prospective randomized multicenter trial evaluating the potential benefit of imaging and blood tests during follow-up after radical surgery for high-risk CMM, compared to clinical examinations only. Primary endpoint is overall survival (OS) at 5 years. Secondary endpoints are survival from diagnosis of relapse and health-related quality of life (HRQoL). Eligible for inclusion are patients radically operated for CMM stage IIB-C or III with sufficient renal function for iv contrast-enhanced CT and who are expected to be fit for treatment in case of recurrence. The planned number of patients is > 1300. Patients are randomized to clinical examinations for 3 years +/- whole-body imaging with CT or FDG-PET/CT and laboratory tests including S100B protein and LDH. This academic study is supported by the Swedish Melanoma Study Group. DISCUSSION: This is the first randomized prospective trial on the potential benefit of imaging as a part of the follow-up scheme after radical surgery for high-risk CMM.

Towards a cancer mission in Horizon Europe: recommendations.

A comprehensive translational cancer research approach focused on personalized and precision medicine, and covering the entire cancer research-care-prevention continuum has the potential to achieve in 2030 a 10-year cancer-specific survival for 75% of patients diagnosed in European Union (EU) member states with a well-developed healthcare system. Concerted actions across this continuum that spans from basic and preclinical research through clinical and prevention research to outcomes research, along with the establishment of interconnected high-quality infrastructures for translational research, clinical and prevention trials and outcomes research, will ensure that science-driven and social innovations benefit patients and individuals at risk across the EU. European infrastructures involving comprehensive cancer centres (CCCs) and CCC-like entities will provide researchers with access to the required critical mass of patients, biological materials and technological resources and can bridge research with healthcare systems. Here, we prioritize research areas to ensure a balanced research portfolio and provide recommendations for achieving key targets. Meeting these targets will require harmonization of EU and national priorities and policies, improved research coordination at the national, regional and EU level and increasingly efficient and flexible funding mechanisms. Long-term support by the EU and commitment of Member States to specialized schemes are also needed for the establishment and sustainability of trans-border infrastructures and networks. In addition to effectively engaging policymakers, all relevant stakeholders within the entire continuum should consensually inform policy through evidence-based advice.

Breast reconstruction patterns from a Swedish nation-wide survey.

OBJECTIVES: The overall aim of the Swedish Breast Reconstruction Outcome Study was to investigate national long-term outcomes after mastectomy with or without breast reconstruction. The current report evaluates breast reconstruction (BR) patterns in Sweden over time. MATERIALS AND METHODS: This is a cross-sectional, registry-based study where all women operated with mastectomy 2000, 2005, 2010 were identified (N = 5853). Geographical differences in type of BR were investigated using heatmaps. Distribution of continuous variables were compared using the Mann-Whitney U test, categorical variables were compared using the chi-square test. RESULTS: Mean age at survey was 69 years (SD=±11.4) and response rate was 50%, responders were on average six years younger than the non-responders and had a more favourable tumor stage (both p < 0.01). Of the 2904 responders, 31% (895/2904) had received a BR: implant-based in 58% (516/895)autologous in 31% (281/895). BR was immediate in 20% (176/895) and delayed in 80% (719/895) women. Women with BR were on average one year older, more often had a normal BMI, reported to be married or had a partner, had a higher educational level and a higher annual income when compared to those without BR (all p < 0.001). The independent factors of not receiving BR were older age and given radiotherapy. CONCLUSIONS: To our knowledge, this is the first national long-term follow-up study on women undergoing mastectomy with and without BR. Around 30% of the survey responders have had a BR with a significant geographical variation highlighting the importance of information, availability and standardisation of indications for BR.

Long-term (up to 16 months) health-related quality of life after adjuvant tailored dose-dense chemotherapy vs. standard three-weekly chemotherapy in women with high-risk early breast cancer.

PURPOSE: To prospectively compare HRQoL effects of two modern adjuvant chemotherapy breast cancer treatment regimens at six time-points up to 16 months after random assignment. METHODS: The open-label, randomized, Phase 3 "Panther trial" was conducted between February 2007 and September 2011. 760 women, aged 65 years and younger, after surgery for non-metastatic node-positive or high-risk node-negative breast cancer were randomized 1:1 to the experimental group (four cycles of tailored and dose-dense adjuvant epirubicin and cyclophosphamide/2 weeks followed by four cycles of tailored dose-dense docetaxel/2 weeks) or standard group (three cycles of fluorouracil and epirubicin-cyclophosphamide/3 weeks followed by three cycles of docetaxel/3 weeks). HRQoL was assessed at all Swedish centres using EORTC QLQ-C30 and EORTC QLQ-BR23 at six points during 16 months before randomization. RESULTS: Response rates to questionnaires were highest at baseline 728/780 (93%) and lowest 16 months after randomization, 557/750 (74%). HRQoL declined during treatment in both groups. At the end of treatment, the experimental group reported statistically significantly lower HRQoL (P < 0.001) than the standard group on global health status, physical functioning, role functioning, social functioning, fatigue, sexual functioning, and systemic therapy effects. No differences were found for emotional functioning, body image, and arm and breast symptoms. There were no statistically significant differences between the groups at the first follow-up and at subsequent assessments. HRQoL levels at the 16-month follow-up were similar to baseline values. CONCLUSIONS: Negative HRQoL impact of the dose-dense and tailored strategy appears to be prominent during treatment, but HRQoL recover once treatment ends.

Whole-body MRI within a surveillance program for carriers with clinically actionable germline TP53 variants - the Swedish constitutional TP53 study SWEP53.

BACKGROUND: The current guidelines in Sweden regarding individuals with a clinically actionable (i.e. pathogenic or likely pathogenic) germline TP53 variant recommend patients to take part of the national Swedish P53 Study (SWEP53). METHODS: The study comprises a patient registry (mandatory for all participants) and three optional parts: a biobank, a surveillance program and a psychosocial evaluation of the surveillance. All known adult eligible carriers regardless of age are offered to take part of the surveillance program offering MRI yearly of the whole-body, breast, and brain as well as breast ultrasound. A special surveillance program is offered for individuals 15-18 years old with a 50% risk of being a mutation carrier or with a verified TP53 variation, includes ultrasound of the abdomen and urine corticosteroid profiles. Clinically motivated further examinations are performed upon need. The national inclusion is performed through the six clinical genetic units in Sweden at Umeå, Uppsala, Stockholm, Gothenburg, Linköping and Lund, and the surveillance is mainly performed through the oncology clinics. RESULTS: To date, a total of 41 adults and 11 children have been included in the study. CONCLUSIONS: The SWEP53 is the first structured national surveillance program including radiological and clinical routines for TP53 mutation carriers in the Scandinavian setting. The aim of this publication is to present and describe the ongoing Swedish surveillance study to encourage the initiation of similar studies and to contribute to the knowledge of adequate clinical handling of these cancer prone families. TRIAL REGISTRATION: Trial registration number: ISRCTN13103571, retrospectively registered on 14/10/2019.
