The psychosocial impact of prostate cancer screening for BRCA1 and BRCA2 carriers.

OBJECTIVES: To report the long-term outcomes from a longitudinal psychosocial study that forms part of the 'Identification of Men with a genetic predisposition to ProstAte Cancer: Targeted Screening in men at higher genetic risk and controls' (IMPACT) study. The IMPACT study is a multi-national study of targeted prostate cancer (PrCa) screening in individuals with a known germline pathogenic variant (GPV) in either the BReast CAncer gene 1 (BRCA1) or the BReast CAncer gene 2 (BRCA2). SUBJECTS AND METHODS: Participants enrolled in the IMPACT study were invited to complete a psychosocial questionnaire prior to each annual screening visit for a minimum of 5 years. The questionnaire included questions on sociodemographics and the following measures: Hospital Anxiety and Depression Scale, Impact of Event Scale, 36-item Short-Form Health Survey, Memorial Anxiety Scale for PrCa, Cancer Worry Scale, risk perception and knowledge. RESULTS: A total of 760 participants completed questionnaires: 207 participants with GPV in BRCA1, 265 with GPV in BRCA2 and 288 controls (non-carriers from families with a known GPV). We found no evidence of clinically concerning levels of general or cancer-specific distress or poor health-related quality of life in the cohort as a whole. Individuals in the control group had significantly less worry about PrCa compared with the carriers; however, all mean scores were low and within reported general population norms, where available. BRCA2 carriers with previously high prostate-specific antigen (PSA) levels experience a small but significant increase in PrCa anxiety (P = 0.01) and PSA-specific anxiety (P < 0.001). Cancer risk perceptions reflected information provided during genetic counselling and participants had good levels of knowledge, although this declined over time. CONCLUSION: This is the first study to report the longitudinal psychosocial impact of a targeted PrCa screening programme for BRCA1 and BRCA2 carriers. The results reassure that an annual PSA-based screening programme does not have an adverse impact on psychosocial health or health-related quality of life in these higher-risk individuals. These results are important as more PrCa screening is targeted to higher-risk groups.

Bladder Preservation for Muscle-Invasive Bladder Cancer With Variant Histology.

A growing body of evidence has shown bladder-preservation with chemo-radiotherapy achieves comparable survival to Radical Cystectomy (5-year OS 50%-70%) and superior quality of life outcomes for patients with muscle-invasive urothelial carcinoma of the bladder (UC). However, up to 55% of patients harbor variant histology and in this review we aim to clarify the role of bladder-preservation for this group. We first draw the distinction between urothelial carcinoma with divergent differentiation (UCDD) and non-urothelial carcinoma (NUC). UCDD is common, increasing in prevalence, and whilst each subtype may have its own characteristics current evidence suggests comparable outcomes with radical cystectomy and bladder-preservation. Non-urothelial carcinoma is a collection of distinct pathologies each deserving of its own management strategy. However, these tumors are rare, and evidence is generated from retrospective studies with significant inherent bias. Small cell carcinoma of the bladder has good evidence for bladder-preservation; however, other pathologies such as Squamous Cell Carcinoma and Adenocarcinoma are not well supported. We recommend careful multidisciplinary appraisal of the evidence for each subtype and honest patient discussion about the limited evidence before reaching management decisions. As we look to the future molecular-profiling may help better characterize these tumors and aid in treatment selection.

Quality of Life After Bladder Cancer: A Cross-sectional Survey of Patient-reported Outcomes.

BACKGROUND: Little is known about health-related quality of life (HRQOL) following treatment for bladder cancer (BC). OBJECTIVE: To determine this, we undertook a cross-sectional survey covering 10% of the English population. DESIGN, SETTING, AND PARTICIPANTS: Participants 1-10 yr from diagnosis were identified through national cancer registration data. INTERVENTION: A postal survey was administered containing generic HRQOL and BC-specific outcome measures. Findings were compared with those of the general population and other pelvic cancer patients. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Generic HRQOL was measured using five-level EQ-5D (EQ-5D-5L) and European Organization for Research and Treatment of Cancer quality of life questionnaire (EORTC QLQ)-C30. BC-specific outcomes were derived from EORTC QLQ-BLM30 and EORTC QLQ-NMIBC24. RESULTS AND LIMITATIONS: A total of 1796 surveys were completed (response rate 55%), including 868 (48%) patients with non-muscle-invasive BC, 893 (50%) patients who received radiotherapy or radical cystectomy, and 35 (1.9%) patients for whom treatment was unknown. Most (69%) of the participants reported at least one problem in any EQ-5D dimension. Age/sex-adjusted generic HRQOL outcomes were similar across all stages and treatment groups, whilst problems increased with age (problems in one or more EQ-5D dimensions: <65 yr [67% {95% confidence interval or CI: 61-74}] vs 85+ yr [84% {95% CI: 81-89}], p = 0.016) and long-term conditions (no conditions [53% {95% CI: 48-58}] vs more than four conditions [94% {95% CI: 90-97}], p < 0.001). Sexual problems were reported commonly in men, increasing with younger age and radical treatment. Younger participants (under 65 yr) reported more financial difficulties (mean score 20 [95% CI: 16-25]) than those aged 85+ yr (6.8 [4.5-9.2], p < 0.001). HRQOL for BC patients (for comparison, males with problems in one or more EQ-5D dimensions 69% [95% CI: 66-72]) was significantly worse than what has been found after colorectal and prostate cancers and in the general population (51% [95% CI: 48-53], all p < 0.05). CONCLUSIONS: HRQOL following BC appears to be relatively independent of disease stage, treatment, and multimodal care. Issues are reported with sexual function and financial toxicity. HRQOL after BC is worse than that after other pelvic cancers. PATIENT SUMMARY: Patients living with bladder cancer often have reduced quality of life, which may be worse than that for other common pelvic cancer patients. Age and other illnesses appear to be more important in determining this quality of life than the treatments received. Many men complain of sexual problems. Younger patients have financial worries.

Treatment Allocation and Survival in Patients Diagnosed with Nonmetastatic Muscle-invasive Bladder Cancer: An Analysis of a National Patient Cohort in England.

BACKGROUND: UK Bladder cancer survival remains low. Nonmetastatic muscle-invasive bladder cancer (MIBC) is potentially curable. It is unclear how many patients receive nonradical treatment owing to advanced age, comorbidities, or alternative factors. OBJECTIVE: To describe treatments and assess survival by disease stage and sex for all newly diagnosed nonmetastatic MIBC in England in 2016, and to observe associations between comorbidities and treatments. DESIGN, SETTING, AND PARTICIPANTS: All new nonmetastatic MIBC diagnoses in England in 2016 were identified retrospectively using National Cancer Registration and Analysis Service, Radiotherapy Datasets, Systemic Anti-Cancer Therapy, and Hospital Episode Statistics databases. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Age, Charlson Comorbidity Index (CCI), and treatments were ascertained, and 1-yr survival was estimated using Pohar-Perme and Kaplan-Meier methods. RESULTS AND LIMITATIONS: Nonmetastatic MIBC diagnoses were registered for 2519 patients (median age 76 yr). Radical cystectomy was performed in 24%, 37% of whom received neoadjuvant chemotherapy (NAC). Radical radiotherapy was performed in 29%, 48% of whom received NAC. NAC alongside radical treatment was associated with higher 1-yr overall survival (OS)-91% (88-93%) with NAC and 83% (80-85%) without (p = 0.05). Nonradical treatments occurred for 47%, with corresponding lower OS. Females with stage II and III disease had significantly lower net survival (NS). Radically treated patients had lower CCIs. CONCLUSIONS: This analysis provides an overview of all nonmetastatic MIBC diagnosed in England in 2016. Just over half of the patients received curative-intent treatment. Of them, only 43% received NAC. One-year OS was disparate, correlating with treatment intensity. Those receiving NAC and radical therapy demonstrated highest OS. Female patients had significantly inferior NS. The data highlight a prescient unmet research need to understand the patient demographic and reasons behind treatment allocation, to address the poor survival observed in those treated nonradically, and the low NAC utilisation. The significantly aged population requires specific future focus. PATIENT SUMMARY: We looked at all patients in England in 2016 who were diagnosed with bladder cancer invading the bladder muscle. Many patients were elderly, and the most intensive treatments aiming for cure were frequently not used. Survival in women was found to be considerably worse, as was survival for less intensively treated patients.

Olaparib in patients with metastatic castration-resistant prostate cancer with DNA repair gene aberrations (TOPARP-B): a multicentre, open-label, randomised, phase 2 trial.

BACKGROUND: Metastatic castration-resistant prostate cancer is enriched in DNA damage response (DDR) gene aberrations. The TOPARP-B trial aims to prospectively validate the association between DDR gene aberrations and response to olaparib in metastatic castration-resistant prostate cancer. METHODS: In this open-label, investigator-initiated, randomised phase 2 trial following a selection (or pick-the-winner) design, we recruited participants from 17 UK hospitals. Men aged 18 years or older with progressing metastatic castration-resistant prostate cancer previously treated with one or two taxane chemotherapy regimens and with an Eastern Cooperative Oncology Group performance status of 2 or less had tumour biopsies tested with targeted sequencing. Patients with DDR gene aberrations were randomly assigned (1:1) by a computer-generated minimisation method, with balancing for circulating tumour cell count at screening, to receive 400 mg or 300 mg olaparib twice daily, given continuously in 4-week cycles until disease progression or unacceptable toxicity. Neither participants nor investigators were masked to dose allocation. The primary endpoint of confirmed response was defined as a composite of all patients presenting with any of the following outcomes: radiological objective response (as assessed by Response Evaluation Criteria in Solid Tumors 1.1), a decrease in prostate-specific antigen (PSA) of 50% or more (PSA50) from baseline, or conversion of circulating tumour cell count (from ≥5 cells per 7·5 mL blood at baseline to <5 cells per 7·5 mL blood). A confirmed response in a consecutive assessment after at least 4 weeks was required for each component. The primary analysis was done in the evaluable population. If at least 19 (43%) of 44 evaluable patients in a dose cohort responded, then the dose cohort would be considered successful. Safety was assessed in all patients who received at least one dose of olaparib. This trial is registered at ClinicalTrials.gov, NCT01682772. Recruitment for the trial has completed and follow-up is ongoing. FINDINGS: 711 patients consented for targeted screening between April 1, 2015, and Aug 30, 2018. 161 patients had DDR gene aberrations, 98 of whom were randomly assigned and treated (49 patients for each olaparib dose), with 92 evaluable for the primary endpoint (46 patients for each olaparib dose). Median follow-up was 24·8 months (IQR 16·7-35·9). Confirmed composite response was achieved in 25 (54·3%; 95% CI 39·0-69·1) of 46 evaluable patients in the 400 mg cohort, and 18 (39·1%; 25·1-54·6) of 46 evaluable patients in the 300 mg cohort. Radiological response was achieved in eight (24·2%; 11·1-42·3) of 33 evaluable patients in the 400 mg cohort and six (16·2%; 6·2-32·0) of 37 in the 300 mg cohort; PSA50 response was achieved in 17 (37·0%; 23·2-52·5) of 46 and 13 (30·2%; 17·2-46·1) of 43; and circulating tumour cell count conversion was achieved in 15 (53·6%; 33·9-72·5) of 28 and 13 (48·1%; 28·7-68·1) of 27. The most common grade 3-4 adverse event in both cohorts was anaemia (15 [31%] of 49 patients in the 300 mg cohort and 18 [37%] of 49 in the 400 mg cohort). 19 serious adverse reactions were reported in 13 patients. One death possibly related to treatment (myocardial infarction) occurred after 11 days of treatment in the 300 mg cohort. INTERPRETATION: Olaparib has antitumour activity against metastatic castration-resistant prostate cancer with DDR gene aberrations, supporting the implementation of genomic stratification of metastatic castration-resistant prostate cancer in clinical practice.

Genomics of lethal prostate cancer at diagnosis and castration resistance.

The genomics of primary prostate cancer differ from those of metastatic castration-resistant prostate cancer (mCRPC). We studied genomic aberrations in primary prostate cancer biopsies from patients who developed mCRPC, also studying matching, same-patient, diagnostic, and mCRPC biopsies following treatment. We profiled 470 treatment-naive prostate cancer diagnostic biopsies and, for 61 cases, mCRPC biopsies, using targeted and low-pass whole-genome sequencing (n = 52). Descriptive statistics were used to summarize mutation and copy number profile. Prevalence was compared using Fisher's exact test. Survival correlations were studied using log-rank test. TP53 (27%) and PTEN (12%) and DDR gene defects (BRCA2 7%; CDK12 5%; ATM 4%) were commonly detected. TP53, BRCA2, and CDK12 mutations were markedly more common than described in the TCGA cohort. Patients with RB1 loss in the primary tumor had a worse prognosis. Among 61 men with matched hormone-naive and mCRPC biopsies, differences were identified in AR, TP53, RB1, and PI3K/AKT mutational status between same-patient samples. In conclusion, the genomics of diagnostic prostatic biopsies acquired from men who develop mCRPC differ from those of the nonlethal primary prostatic cancers. RB1/TP53/AR aberrations are enriched in later stages, but the prevalence of DDR defects in diagnostic samples is similar to mCRPC.

The impact of the 21-gene assay on adjuvant treatment decisions in oestrogen receptor-positive early breast cancer: a prospective study.

BACKGROUND: International guidelines, including NICE, recommend using the 21-gene Recurrence Score assay for guiding adjuvant treatment decisions in ER+, HER2-negative early breast cancer (BC). We investigated the impact of adding this assay to standard pathological tests on clinicians'/patients' treatment decisions and on patients' decisional conflict in the United Kingdom. METHODS: In this prospective multicentre study, eligibility criteria included: ER+ HER2-negative BC (N0/Nmic for patients ⩽50 years; ⩽3 positive lymph nodes for patients >50 years) and being fit for chemotherapy. Physicians'/patients' treatment choices and patients' decisional conflict were recorded pre- and post testing. RESULTS: The analysis included 137 patients. Overall, adjuvant treatment recommendations changed in 40.7% of patients, with the direction of the change consistent with the Recurrence Score results (net decrease in chemotherapy recommendation rate in low Recurrence Score patients and net increase in high Recurrence Score patients). Patients' choices were generally consistent with physicians' recommendations. Post-testing, patients' decisional conflict decreased significantly (P<0.0001). In the 67 patients meeting the NICE criteria for testing, the recommendation change rate was 49.3%. CONCLUSIONS: Recurrence Score testing significantly influenced treatment recommendations overall and in the subgroup of patients meeting the NICE criteria, suggesting that this test could substantially alter treatment patterns in the United Kingdom.

Primary chemotherapy for inoperable ovarian, fallopian tube, or primary peritoneal cancer with or without delayed debulking surgery.

OBJECTIVE: To describe the outcome of primary chemotherapy for women with advanced-stage epithelial ovarian or primary peritoneal cancer and delayed surgery when optimal debulking surgery cannot be achieved at diagnosis. METHODS: Between 1998 and 2006, we retrospectively reviewed the overall survival and examined prognostic markers in consecutive patients who were not suitable for initial radical surgery because of the extent of disease and/or poor performance status. They were treated with a policy of primary platinum-based chemotherapy, followed whenever possible in responding patients by debulking surgery. RESULTS: A total of 171 patients received least one cycle of chemotherapy. Eighty-six patients proceeded to surgery and 53 (31% of 171 and 62% of 86) had optimal (<1 cm) residual disease. Eighty-five patients did not undergo surgery because they remained unfit or had not responded sufficiently to chemotherapy. The median overall survival was 18.7 months (95% confidence interval [CI], 16.5-24.2). The median OS in the surgical group for optimal and suboptimal surgery was 40.8 (95% CI, 32.5-50.0) and 22.5 (95% CI, 17.7-37.1) months (P = 0.005). On multivariate analysis, interval surgery and optimal surgery were the only independent prognostic factors (hazard ratios, 0.45 and 0.43, respectively; P = 0.009). In the nonsurgical group, CA125 response was an independent prognostic factor (hazard ratio, 0.34; P = 0.001) with an OS of 21.7 months (95% CI, 14.0-35.4) in women with a normal CA125 after treatment compared with 6.7 (95% CI, 4.5-7.8) months. CONCLUSIONS: In one third of the women, the tumor was optimally debulked after primary chemotherapy and their median survival was 40.8 months. Suboptimal debulking surgery after primary chemotherapy did not result in a better survival than that achieved after a chemotherapy response alone, suggesting that surgery may be avoided when imaging after chemotherapy demonstrates residual disease that cannot be optimally debulked.

Thrombotic microangiopathy following docetaxel and trastuzumab chemotherapy: a case report.

Thrombotic microangiopathy is a rare haematological emergency which encompasses the conditions of haemolytic uraemic syndrome (HUS) and thrombotic thrombocytopenic purpura (TTP). It is an unusual but recognised complication of chemotherapy. It has not previously been described in conjunction with docetaxel or trastuzumab therapy. We report a 47-year-old patient with localised breast cancer who developed thrombotic microangiopathy (HUS/TTP) acutely following concurrent neoadjuvant therapy with trastuzumab and docetaxel. We demonstrate from our case that mild confusion occurring on a background of mild anaemia and thrombocytopenia may sometimes be the only clue to the diagnosis. Clinicians should be aware of the possibility of thrombotic microangiopathy associated with trastuzumab and docetaxel therapy, as early intervention can improve clinical outcome.
