RESUMO
BACKGROUND: In a phase 2 study, rucaparib, an inhibitor of poly(ADP-ribose) polymerase (PARP), showed a high level of activity in patients who had metastatic, castration-resistant prostate cancer associated with a deleterious BRCA alteration. Data are needed to confirm and expand on the findings of the phase 2 study. METHODS: In this randomized, controlled, phase 3 trial, we enrolled patients who had metastatic, castration-resistant prostate cancer with a BRCA1, BRCA2, or ATM alteration and who had disease progression after treatment with a second-generation androgen-receptor pathway inhibitor (ARPI). We randomly assigned the patients in a 2:1 ratio to receive oral rucaparib (600 mg twice daily) or a physician's choice control (docetaxel or a second-generation ARPI [abiraterone acetate or enzalutamide]). The primary outcome was the median duration of imaging-based progression-free survival according to independent review. RESULTS: Of the 4855 patients who had undergone prescreening or screening, 270 were assigned to receive rucaparib and 135 to receive a control medication (intention-to-treat population); in the two groups, 201 patients and 101 patients, respectively, had a BRCA alteration. At 62 months, the duration of imaging-based progression-free survival was significantly longer in the rucaparib group than in the control group, both in the BRCA subgroup (median, 11.2 months and 6.4 months, respectively; hazard ratio, 0.50; 95% confidence interval [CI], 0.36 to 0.69) and in the intention-to-treat group (median, 10.2 months and 6.4 months, respectively; hazard ratio, 0.61; 95% CI, 0.47 to 0.80; P<0.001 for both comparisons). In an exploratory analysis in the ATM subgroup, the median duration of imaging-based progression-free survival was 8.1 months in the rucaparib group and 6.8 months in the control group (hazard ratio, 0.95; 95% CI, 0.59 to 1.52). The most frequent adverse events with rucaparib were fatigue and nausea. CONCLUSIONS: The duration of imaging-based progression-free survival was significantly longer with rucaparib than with a control medication among patients who had metastatic, castration-resistant prostate cancer with a BRCA alteration.

PURPOSE: To identify supportive care interventions for men with urological cancers. METHODS: Experimental studies conducted among men with any urological cancer were eligible for inclusion. Academic Search Complete, CINAHL Plus with Full Text, MEDLINE, APA PsycArticles, APA PsycInfo, Social Sciences Full Text (H.W. Wilson), SocINDEX with Full Text, ERIC, Google Scholar and ClinicalTrials.gov were searched on 6 December 2022. No database limits were applied. The included studies were methodologically appraised. A narrative synthesis of the results was conducted. RESULTS: Thirty studies were included with 10 categories of interventions identified. Over 300 outcomes were measured, and more than 100 instruments were used. Multicomponent interventions generally led to positive changes in physiological outcomes like body mass index, as well as exercise tolerance and quality of life. This change, however, was not sustained in the long term. Cognitive-behavioural interventions significantly improved psychological symptoms but seldom physical symptoms. Telephone and web-based interventions showed great promise in improving outcomes like depression, positive affect, negative affect, perceived stress, spiritual wellbeing and fatigue. Findings from physical activity/exercise-based interventions were promising for both, physical and psychological outcomes. Rehabilitative interventions were associated with significant improvements in quality of life, urinary symptoms and psychological symptoms, albeit in the short term. Mixed results were reported for nurse-led interventions, family-based interventions and nutritional interventions. CONCLUSION: All but one study focused exclusively on prostate cancer. The included studies were significantly heterogeneous. Multicomponent, cognitive-behavioural, telephone and web-based, physical activity/exercise-based and rehabilitative interventions showed great promise in improving various outcomes. This improvement, however, was often short-lived.

The COVID-19 pandemic compounded isolation for patients through social distancing measures and staff shortages. We were concerned about the impact of COVID-19 on the quality of care provided at end-of-life in 2021 in a national cancer centre, and instigated the first ever review of the care of the dying. Quality of care was assessed retrospectively using a validated instrument developed by the United Kingdom's National Quality Board. Sixty-six patient deaths occurred in our cancer centre in 2021. The 'risk of dying' was documented in 65.2% of records. Palliative care services were involved in 77%, and pastoral care in 10.6%. What was important to the patient was documented in 24.2%. The 'quality-of-death' score was satisfactory for most but poor in 21.2%. Our study prompted change, including appointment of an end-of-life coordinator, development of a checklist to ensure comprehensive communication, expansion of the end-of-life committee to include junior doctors, and regular audit.
RESUMO
INTRODUCTION: "Transgender" and "gender diverse" are umbrella terms encompassing those whose gender identities or expressions differ from those typically associated with the sex they were assigned at birth. There is scant global information on cancer incidence, outcome, and mortality for this cohort. This group may present with advanced cancer, have mistrust in health care services and report anxiety and depression at higher frequencies, a finding often seen in marginalized groups because of minority stress. MATERIALS AND METHODS: Medical oncologists were contacted by secure email to identify patients who self-identify as transgender and gender diverse in three Irish hospitals. Five patients were identified. A retrospective chart review was conducted and a pseudonymized patient survey was distributed. RESULTS: All patients included in our chart review (n = 5) were diagnosed with advanced disease on initial diagnosis. Two patients identified as men, two as women, and one as a transwoman. Two of five patients' health record charts reflected a name or gender change. Three patients had gender transitioning treatment postponed. Assessing comorbidities, it was seen that four patients required psychiatry input. Predominant issues noted in our patient survey by the two respondents (n = 2) were "mis-gendering," lack of a gender-neutral hospital environment, lack of inclusion in cancer groups, and barriers in changing name and/or sex on hospital records. CONCLUSION: Components of care requiring revision include patient accessible pathways to change names and gender on health records, earlier access to psychological support and targeted screening and support groups. Resources for hospital staff to improve awareness of correct terminology and to provide gender neutral facilities are worthwhile. IMPLICATIONS FOR PRACTICE: The implications for practice on an international level include patient-friendly pathways for changing hospital name and gender so that patients may feel comfortable using wristbands. The need for international screening guidelines for transgender patients and national transgender cancer support groups is highlighted. On a day-to-day level for providers, the correct use of pronouns makes a big difference to patients. Asking about preferred pronoun on first visit and noting on patient's file is worthwhile. It is important for providers to know that increased psychological support should be offered early on first clinic visit and engaged with as necessary when patient has a history of anxiety or depression. Providers should discuss openly that some gender transitioning treatment will be postponed because of cancer care and refer to both the physical and psychological sequelae of this. Asking transgender patients which room or bathroom they would prefer when rooms are gendered is essential.

BACKGROUND: The authors evaluated mocetinostat (a class I/IV histone deacetylase inhibitor) in patients with urothelial carcinoma harboring inactivating mutations or deletions in CREB binding protein [CREBBP] and/or E1A binding protein p300 [EP300] histone acetyltransferase genes in a single-arm, open-label phase 2 study. METHODS: Eligible patients with platinum-treated, advanced/metastatic disease received oral mocetinostat (at a dose of 70 mg 3 times per week [TIW] escalating to 90 mg TIW) in 28-day cycles in a 3-stage study (ClinicalTrials.gov identifier NCT02236195). The primary endpoint was the objective response rate. RESULTS: Genomic testing was feasible in 155 of 175 patients (89%). Qualifying tumor mutations were CREBBP (15%), EP300 (8%), and both CREBBP and EP300 (1%). A total of 17 patients were enrolled into stage 1 (the intent-to-treat population); no patients were enrolled in subsequent stages. One partial response was observed (11% [1 of 9 patients; the population that was evaluable for efficacy comprised 9 of the 15 planned patients]); activity was deemed insufficient to progress to stage 2 (null hypothesis: objective response rate of ≤15%). All patients experienced ≥1 adverse event, most commonly nausea (13 of 17 patients; 77%) and fatigue (12 of 17 patients; 71%). The median duration of treatment was 46 days; treatment interruptions (14 of 17 patients; 82%) and dose reductions (5 of 17 patients; 29%) were common. Mocetinostat exposure was lower than anticipated (dose-normalized maximum serum concentration [Cmax ] after TIW dosing of 0.2 ng/mL/mg). CONCLUSIONS: To the authors' knowledge, the current study represents the first clinical trial using genomic-based selection to identify patients with urothelial cancer who are likely to benefit from selective histone deacetylase inhibition. Mocetinostat was associated with significant toxicities that impacted drug exposure and may have contributed to modest clinical activity in these pretreated patients. The efficacy observed was considered insufficient to warrant further investigation of mocetinostat as a single agent in this setting.

BACKGROUND: Pemetrexed is a commonly used treatment for platinum-resistant advanced urothelial carcinoma (UC) based on objective response rates of 8% and 28% in two small phase II studies. To address the discrepancy in reported response rates and to assess efficacy and toxicity outside of a clinical trial setting, we performed a large retrospective analysis of pemetrexed use at Memorial Sloan Kettering Cancer Center. We also investigated candidate prognostic factors for overall survival in this setting to explore whether the neutrophil-lymphocyte ratio (NLR) had independent prognostic significance. PATIENTS AND METHODS: Patients receiving pemetrexed for platinum-resistant advanced UC between 2008 and 2013 were identified. The Response Evaluation Criteria in Solid Tumors (RECIST, version 1.1) were used to determine response rate. Kaplan-Meier and Cox regression analyses were used to examine the association of various factors with efficacy and survival outcomes. Hematologic toxicity and laboratory abnormalities were recorded. RESULTS: One hundred and twenty-nine patients were treated with pemetrexed. The objective response rate was 5% (95% confidence interval: 1%-9%), and the median duration of response was 8 months. Median progression-free survival (PFS) was 2.4 months, and the 6-month PFS rate was 14%. There was no significant difference in response rate by age, Eastern Cooperative Oncology Group (ECOG) performance status, or number of prior therapies. On multivariable analysis, ECOG performance status (p < .01), liver metastases (p = .02), and NLR (p < .01) had independent prognostic significance for overall survival. CONCLUSION: This 129-patient series is the largest reported data set describing pemetrexed use in advanced UC. Activity was modest, although discovery of molecular biomarkers predictive of response would be valuable to identify the small subset of patients who do gain significant benefit. Overall, the data highlight the urgent need to develop novel therapies for these patients.

BACKGROUND: To date, there have been no reports characterizing the genome-wide somatic DNA chromosomal copy-number alteration landscape in metastatic urothelial carcinoma. We sought to characterize the DNA copy-number profile in a cohort of metastatic samples and compare them to a cohort of primary urothelial carcinoma samples in order to identify changes that are associated with progression from primary to metastatic disease. METHODS: Using molecular inversion probe array analysis we compared genome-wide chromosomal copy-number alterations between 30 metastatic and 29 primary UC samples. Whole transcriptome RNA-Seq analysis was also performed in primary and matched metastatic samples which was available for 9 patients. RESULTS: Based on a focused analysis of 32 genes in which alterations may be clinically actionable, there were significantly more amplifications/deletions in metastases (8.6% vs 4.5%, p < 0.001). In particular, there was a higher frequency of E2F3 amplification in metastases (30% vs 7%, p = 0.046). Paired primary and metastatic tissue was available for 11 patients and 3 of these had amplifications of potential clinical relevance in metastases that were not in the primary tumor including ERBB2, CDK4, CCND1, E2F3, and AKT1. The transcriptional activity of these amplifications was supported by RNA expression data. CONCLUSIONS: The discordance in alterations between primary and metastatic tissue may be of clinical relevance in the era of genomically directed precision cancer medicine.

BACKGROUND: DNA aptamers represent a novel strategy in anti-cancer medicine. AS1411, a DNA aptamer targeting nucleolin (a protein which is overexpressed in many tumor types), was evaluated in patients with metastatic, clear-cell, renal cell carcinoma (RCC) who had failed treatment with ≥1 prior tyrosine kinase inhibitor. METHODS: In this phase II, single-arm study, AS1411 was administered at 40 mg/kg/day by continuous intravenous infusion on days 1-4 of a 28-day cycle, for two cycles. Primary endpoint was overall response rate; progression-free survival (PFS) and safety were secondary endpoints. RESULTS: 35 patients were enrolled and treated. One patient (2.9 %) had a response to treatment. The response was dramatic (84 % reduction in tumor burden by RECIST 1.0 criteria) and durable (patient remains free of progression 2 years after completing therapy). Whole exome sequencing of this patient's tumor revealed missense mutations in the mTOR and FGFR2 genes which is of interest because nucleolin is known to upregulate mTOR pathway activity by enhancing AKT1 mRNA translation. No other responses were seen. Thirty-four percent of patients had an AS1411-related adverse event, all of which were mild or moderate. CONCLUSIONS: AS1411 appears to have minimal activity in unselected patients with metastatic RCC. However, rare, dramatic and durable responses can be observed and toxicity is low. One patient in this study had an excellent response and was found to have FGFR2 and mTOR mutations which will be of interest in future efforts to discover and validate predictive biomarkers of response to nucleolin targeted compounds. DNA aptamers represent a novel way to target cancer cells at a molecular level and continue to be developed with a view to improving treatment and imaging in cancer medicine.

BACKGROUND: While biologic drugs have demonstrated efficacy across a range of indications, patient access to these drugs is constrained due to their high cost. Biosimilars provide a means to increase patient access while reducing the financial burden. AIMS: The primary objective was to determine the current usage of biosimilar and reference trastuzumab and rituximab in four Irish hospitals. A secondary objective involved determining barriers to biosimilar usage. METHODS: This project involved a retrospective chart review to analyse the usage of reference and biosimilar versions of trastuzumab and rituximab. Additionally, a prospective cross-sectional study identified barriers to the usage of biosimilars via the distribution of a novel questionnaire to patients, pharmacists, doctors and students. RESULTS: The utilisation of biosimilar intravenous trastuzumab and rituximab ranged from 39 to 100%, and 0 to 89%, respectively. A total of n = 479 questionnaire responses were included. Biosimilar awareness was significantly lower among 'Doctors and Medical Students' (45.3%; 95% [CI, 33.8-57.3%]) compared to 'Pharmacists and Pharmacy Students' (97.1%; 95% [CI, 94-98.8%; comparison p < 0.001]). A significant majority of healthcare professionals agreed biosimilars should have consistent nomenclature (p < 0.001). A significant majority of patients (87.3%, 95% [CI, 81.3-92%; p < 0.001]) indicated that they would agree to commence using a biosimilar medicine. CONCLUSION: Biosimilar versions of trastuzumab and rituximab were in use to a variable extent. There remains a considerable opportunity to further increase the usage to maximise their potential benefits. A series of challenges were identified including reduced awareness among the medical profession and lack of clear nomenclature.

Background: Soft tissue sarcoma (STS) is comprised of approximately 80 subtypes, with an incidence of 4 - 5 per 100,000 annually in Europe. The National Comprehensive Cancer Network (NCCN) guidelines recommend consideration of neoadjuvant/adjuvant chemotherapy in tumors at high risk of recurrence based on the American Joint Committee on Cancer (AJCC) staging. Alternatively, the Sarculator is a risk prediction tool that has identified a threshold of risk, above which chemotherapy may provide an overall survival (OS) benefit. Using this nomogram, patients with a 10-year predicted OS < 60% are classified as high risk and should be considered for chemotherapy. The aim of this study was to assess the prognostic accuracy of these two risk prediction methods in an Irish population. Methods: All newly diagnosed patients with resected STS discussed in the STS tumor board in Cork University Hospital between January 2012 and December 2021 were identified. Clinicopathological data were collected. Risk assessment using AJCC and Sarculator nomogram was performed on all patients with an extremity/trunk sarcoma. The OS was calculated including Kaplan-Meier method for time to event analysis. Results: In total, 200 STS patients were reviewed, of whom 134 had truncal or extremity tumors. Sarculator score was calculated for 60 of these (well differentiated liposarcomas, desmoid tumors and dermatofibrosarcoma protuberans were excluded). Using the Sarculator nomogram to calculate 10-year predicted OS, 19 patients were categorized as high risk and 41 were categorized as low risk. Using AJCC staging, 25 patients were categorized as high risk and 35 as low risk. The 5-year OS rate in the Sarculator high-risk group was 60.2%, compared with 87.1% in the low-risk group (P = 0.009). The 5-year OS rate in the AJCC high-risk group was 67.6%, compared with 86.3% in the low-risk group (P = 0.083). Conclusions: Our cohort is representative of the broad histological subtypes expected. In our population, Sarculator score results correlate with international outcomes and higher scores were associated with increased mortality. The Sarculator was more predictive of clinical outcome than AJCC staging, and its use would lower the proportion of patients being considered for adjuvant chemotherapy thereby sparing toxicity, which is important in the setting of uncertain clinical benefit.
RESUMO
INTRODUCTION: Cyberattacks represent a growing threat for healthcare delivery globally. We assess the impact and implications of a cyberattack on a cancer center in Ireland. METHODS: On May 14th 2021 (day 0) Cork University Hospital (CUH) Cancer Center was involved in the first national healthcare ransomware attack in Ireland. Contingency plans were only present in laboratory services who had previously experienced information technology (IT) failures. No hospital cyberattack emergency plan was in place. Departmental logs of activity for 120 days after the attack were reviewed and compared with historical activity records. Daily sample deficits (routine daily number of samples analyzed - number of samples analyzed during cyberattack) were calculated. Categorical variables are reported as median and range. Qualitative data were collected via reflective essays and interviews with key stakeholders from affected departments in CUH. RESULTS: On day 0, all IT systems were shut down. Radiotherapy (RT) treatment and cancer surgeries stopped, outpatient activity fell by 50%. hematology, biochemistry and radiology capacity fell by 90% (daily sample deficit (DSD) 2700 samples), 75% (DSD 2250 samples), and 90% (100% mammography/PET scan) respectively. Histopathology reporting times doubled (7 to 15 days). Radiotherapy (RT) was interrupted for 113 patients in CUH. The median treatment gap duration was six days for category 1 patients and 10 for the remaining patients. Partner organizations paused all IT links with CUH. Outsourcing of radiology and radiotherapy commenced, alternative communication networks and national conference calls in RT and Clinical Trials were established. By day 28 Email communication was restored. By day 210 reporting and data storage backlogs were cleared and over 2000 computers were checked/replaced. CONCLUSION: Cyberattacks have rapid, profound and protracted impacts. While laboratory and diagnostic deficits were readily quantified, the impact of disrupted/delayed care on patient outcomes is less readily quantifiable. Cyberawareness and cyberattack plans need to be embedded in healthcare. POLICY SUMMARY: Cyberattacks pose significant challenges for healthcare systems, impacting patient care, clinical outcomes, and staff wellbeing. This study provides a comprehensive review of the impact of the Conti ransomware attack on cancer services in Cork University Hospital (CUH), the first cyberattack on a national health service. Our study highlights the widespread disruption caused by a cyberattack including shutdown of information technology (IT) services, marked reduction in outpatient activity, temporary cessation of essential services such as radiation therapy. We provide a framework for other institutions for mitigating the impact of a cyberattack, underscoring the need for a cyberpreparedness plan similar to those made for natural disasters and the profound legacy of a cyberattack on patient care.

BACKGROUND: Expanded access programs (EAPs) allow cancer patients with unmet clinical need to obtain access to pre-authorisation treatments. There is no standardised process for implementing these programs nationally, and real-world data on their impact is lacking. AIMS: This study aimed to evaluate the prevalence of such EAPs and their impact in a cancer centre. METHODS: Data relating to adult cancer patients treated via EAPs from 2011 to 2021 in three Cork university hospitals was collated. Descriptive statistics were employed to get an overview of the impact these programs currently have on cancer care provision. RESULTS: We identified 193 patients who accessed EAPs during the study period, availing of 33 separate drugs for a total of 50 different cancer indications. The prevalence of EAP usage was shown to have been trending upwards in recent years with a total of 189 programs being accessed throughout the period. Drugs provided were from a number of different anti-cancer drug classes, particularly targeted therapies (n = 18) and immune checkpoint inhibitors (n = 17). Cancers from a wide range of both solid and liquid tumour types were treated with EAP drugs, and patients treated were from across a broad spectrum of ages (26-82, SD 11.99). CONCLUSIONS: EAPs have an increasing role in accessing novel cancer therapies in our community and by extension nationally. Equity of EAP access would be facilitated by a national registry of available agents which we have established. Assessment of their benefits and toxicities would be enhanced by the requirement for a real-world database as a condition of EAP approval.
RESUMO
PURPOSE OF REVIEW: Thirty-five percent of bladder cancer patients either present with or develop muscle-invasive disease. The current standard of care for these patients is neoadjuvant chemotherapy followed by radical cystoprostatectomy or combined chemoradiotherapy. Despite these therapies, approximately 50% of patients will relapse after definitive locoregional treatment and eventually succumb to their disease. RECENT FINDINGS: Therapies targeted at altered genetic pathways have proven efficacy in localized solid tumors including breast cancer, head and neck cancer and GIST. No such treatments have proven clinical benefit in bladder cancer, but targets under active investigation include HER2, epidermal growth factor receptors, fibroblast growth factor receptor 3, mTOR and others. Efforts are also underway to genetically define the subgroup of patients, which benefit from systemic platinum-based chemotherapy in this setting. SUMMARY: Ongoing clinical trials are investigating the role of treatments targeted at actionable genetic mutations in bladder cancer. The key to maximizing the potential benefit from this treatment approach will be the identification of predictive biomarkers of response, the identification of safe combinations which block multiple signaling molecules synchronously, and the availability of faster, cheaper genetic testing in the clinic.

INTRODUCTION/AIMS: There are disparities in the availability of systemic anticancer therapies (SACTs) globally. We set out to investigate the cost and reimbursement of SACTs in the United Kingdom (UK) and the Republic of Ireland (ROI) in conjunction with efficacy and licensing authority decisions in the United States (US) and the European Union (EU). METHODS: We sought data pertaining to licensing in the EU, reimbursement in ROI/UK and cost/efficacy of SACTs licensed by the Food and Drug Administration (FDA) between January 2015 and May 2021. Independent samples t tests, chi-square test and Pearson's correlation were used for statistical analysis. RESULTS: We identified that the majority of FDA-approved regimens are licensed by the European Medicines Agency (EMA) (n = 91, 67.9%). However, only a minority of these are currently reimbursed in the UK (n = 60, 45%) or the ROI (n = 28, 21%) as of the 1st of May 2021. In addition, only a minority of regimens have demonstrated a statistically significant OS benefit (n = 54, 40%). There was no association between cost of regimens and either the presence (t = 0.846, p = 0.40) or duration of OS benefit (t = - 0.84, p = 0.64). CONCLUSIONS: Our study highlights that many licensed systemic anticancer treatments are not currently reimbursed in ROI/UK. The high cost of these medicines is independent of the presence of an OS benefit. Collaboration between regulatory agencies, governments and industry partners is needed to ensure health expenditure is directed towards the most effective treatments.

Purpose: To investigate the feasibility of implementing a remote patient monitoring system using an electronic patient-reported outcomes (ePROs) platform in a tertiary cancer center in the Republic of Ireland. Methods: Patients receiving oral chemotherapy and oncology clinicians were invited to participate in the study. Patients were asked to submit weekly symptom questionnaires through an ePRO mobile phone application (app)-ONCOpatient®. Clinical staff were invited to use the ONCOpatient® clinician interface. After 8 weeks all participants submitted evaluation questionnaires. Results: Thirteen patients and five staff were enrolled in the study. The majority of patients were female (85%) with a median age of 48 years (range 22-73). Most (92%) were enrolled over telephone requiring on average 16â minutes. Compliance with the weekly assessments was 91%. Alerts were triggered by 40% of patients who then required phone calls to aid with symptom management. At the end of study, 87% of patients reported they would use the app frequently, 75% reported that the platform met their expectations, and 25% that it exceeded their expectations. Similarly, 100% of staff reported they would use the app frequently, 60% reported that it met their expectations, and 40% that it exceeded their expectations. Conclusions: Our pilot study showed that it is feasible to implement ePRO platforms in the Irish clinical setting. Small sample bias was recognized as a limitation, and we plan to confirm our findings on a larger cohort of patients. In the next phase we will integrate wearables including remote blood pressure monitoring.
RESUMO
Aim: Adjuvant chemotherapy in NSCLC is associated with modest benefits and significant toxicity. We sought to evaluate the toxicity of adjuvant chemotherapy and disease-specific outcomes in a real-world population. Methods: We performed a retrospective analysis of patients undergoing adjuvant chemotherapy for NSCLC in an Irish center over a 7-year period. We described treatment-associated toxicity, recurrence-free survival and overall survival. Results: 62 patients underwent adjuvant chemotherapy. Treatment-associated hospitalisation occurred in 29% of patients. Relapse was recorded in 56% of patients and median recurrence-free survival was 27 months. Conclusion: High rates of disease recurrence and treatment-associated morbidity were observed in patients receiving adjuvant chemotherapy for NSCLC. Novel therapeutic strategies are required to improve outcomes in this population.
Early NSCLC is primarily managed with lung cancer surgery. Chemotherapy is offered to some patients with early NSCLC after surgery depending on the size of the tumor and lymph node involvement. The benefit of post-surgery (adjuvant) chemotherapy in reducing the chance of cancer recurrence has been shown to be relatively small in previous studies. Large studies of post-surgery chemotherapy in NSCLC have included limited numbers of older patients, and patients with significant medical issues. This study looked to evaluate the safety and treatment-associated side effects of adjuvant chemotherapy in a group of patients more reflective of everyday clinical practice, and to assess the rates of cancer recurrence in these patients. In our study of 62 patients who underwent adjuvant chemotherapy for NSCLC, nearly 1 in 3 patients required hospital admission due to treatment-associated side effects. Almost 40% of patients experienced significant blood test abnormalities (including anaemia, reduced platelets, and reduced white blood cells). Approximately 1 in 4 patients required a reduction in the doses of their treatment due to treatment-associated side effects. More than half of the patients in our study experienced a recurrence of their cancer. Our study demonstrates the significant side effects associated with adjuvant chemotherapy in NSCLC and highlights the need for better-tolerated treatment strategies to reduce cancer recurrence in early NSCLC.
RESUMO
BACKGROUND: Initial TRITON2 (NCT02952534) results demonstrated the efficacy of rucaparib 600 mg BID in patients with metastatic castration-resistant prostate cancer (mCRPC) associated with a BRCA1 or BRCA2 (BRCA) or other DNA damage repair (DDR) gene alteration. OBJECTIVE: To present the final data from TRITON2. DESIGN, SETTING, AND PARTICIPANTS: TRITON2 enrolled patients with mCRPC who had progressed on one or two lines of next-generation androgen receptor-directed therapy and one taxane-based chemotherapy. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The primary endpoint was objective response rate (ORR; as per the modified Response Evaluation Criteria in Solid Tumor Version 1.1/Prostate Cancer Clinical Trials Working Group 3 criteria in patients with measurable disease by independent radiology review [IRR]); prostate-specific antigen (PSA) response rate (≥50% decrease from baseline [PSA50]) was a key secondary endpoint. RESULTS AND LIMITATIONS: As of July 27, 2021 (study closure), TRITON2 had enrolled 277 patients, grouped by mutated gene: BRCA (n = 172), ATM (n = 59), CDK12 (n = 15), CHEK2 (n = 7), PALB2 (n = 11), or other DDR gene (Other; n = 13). ORR by IRR was 46% (37/81) in the BRCA subgroup (95% confidence interval [CI], 35-57%), 100% (4/4) in the PALB2 subgroup (95% CI, 40-100%), and 25% (3/12) in the Other subgroup (95% CI, 5.5-57%). No patients within the ATM, CDK12, or CHEK2 subgroups had an objective response by IRR. PSA50 response rates (95% CI) in the BRCA, PALB2, ATM, CDK12, CHEK2, and Other subgroups were 53% (46-61%), 55% (23-83%), 3.4% (0.4-12), 6.7% (0.2-32%), 14% (0.4-58%), and 23% (5.0-54%), respectively. CONCLUSIONS: The final TRITON2 results confirm the clinical benefit and manageable safety profile of rucaparib in patients with mCRPC, including those with an alteration in BRCA or select non-BRCA DDR gene. PATIENT SUMMARY: Almost half of TRITON2 patients with BRCA-mutated metastatic castration-resistant prostate cancer had a complete or partial tumor size reduction with rucaparib; clinical benefits were also observed with other DNA damage repair gene alterations.

UNLABELLED: What's known on the subject? and What does the study add? Prostate cancer is a heterogeneous disease and biomarkers to predict its incidence and subsequent clinical behaviour are needed to tailor screening, prevention and therapeutic strategies. Rare mutations in genes such as BRCA1, BRCA2 and HOXB13 can affect prostate cancer incidence and/or clinical behaviour. Genome wide association studies (GWAS) have identified more common genetic variations that explain an estimated 20% of familial prostate cancer risk. In this review, we focus on the potential of germline genetic variation to provide biomarkers for prostate cancer screening, prevention and management. We discuss how germline genetics may have a role in treatment selection if reliable pharmacogenetic predictors of efficacy and toxicity can be identified. We have outlined possible mechanisms for including germline investigation in future prostate cancer clinical trials. OBJECTIVES: ⢠Prostate cancer is a heterogeneous disease and biomarkers to predict its incidence and subsequent clinical behaviour are needed to tailor screening, prevention and therapeutic strategies. ⢠In this review we focus on the potential of germline genetic variation to provide these biomarkers.

A 59-year-old man with a known breast cancer type 1 gene mutation and a 2-year history of metastatic prostate cancer to bone and lymph nodes presented with a sudden onset of thunderclap headache, photophobia and a left sided facial droop. He was being treated at the time with the poly ADP ribose polymerase inhibitor Rucaparib. Of note, 6 weeks prior to this presentation, he had been diagnosed with malignant spinal cord compression at T3-T6, he underwent an emergency decompressive laminectomy and had received palliative postoperative radiotherapy. An urgent CT brain revealed dural metastases from his prostate cancer, with extensive oedema and midline shift. He underwent palliative whole brain radiotherapy but died 2 weeks later.
