What is this summary about?: This is a summary of a paper that describes the results of the SPARTAN and TITAN studies, which looked at whether a treatment called apalutamide can help treat individuals with advanced prostate cancer.The SPARTAN study included 1207 participants with nonmetastatic castration-resistant prostate cancer (or nmCRPC). The TITAN study included 1052 participants with metastatic castration-sensitive prostate cancer (or mCSPC). Treatment with apalutamide was compared with treatment with placebo. In both studies, all participants were also given androgen deprivation therapy (or ADT), which has been used for many years for the treatment of prostate cancer.The results showed that treatment with apalutamide plus ADT increased participants' survival time while their health-related quality of life stayed the same, compared with placebo plus ADT. Also, apalutamide plus ADT increased the length of time that the cancer did not spread to other parts of the body (metastasize) or did not continue to grow. In both studies, treatment with apalutamide plus ADT was associated with a deep decline in blood prostate-specific antigen (or PSA) levels (called a deep PSA decline). This additional analysis of the SPARTAN and TITAN studies was performed to understand whether the deep PSA decline in participants who received apalutamide plus ADT was linked to their overall health-related quality of life.

What were the results of the additional analysis?: In participants who received apalutamide plus ADT, those who achieved a deep PSA decline after the start of treatment had a greater chance that their health-related quality of life would remain stable. When participants achieved a deep PSA decline at 3 months after the start of treatment, the benefit to their health-related quality of life, including physical wellbeing, was even greater.

What do these results mean for individuals with advanced prostate cancer?: For individuals with advanced prostate cancer, it is important to monitor both PSA decline and any impacts on health-related quality of life. These results will help doctors and other healthcare professionals have a better understanding of patients' cancer experience and the impact of their treatment.Clinical Trial Registration: NCT01946204 (SPARTAN) and, NCT02489318 (TITAN) (ClinicalTrials.gov).

Background: In first/second generation EGFR-TKIs, strong PD-L1 expression contributes to primary resistance, significantly affecting patient prognosis. The relationship between PD-L1 expression levels and third-generation TKIs remains unclear.Methods: This study analyzed advanced NSCLC who received third-generation EGFR-TKIs as first-line systemic therapy from March 2019 to June 2022. The EGFR and PD-L1 status of the patients was also assessed.Results: Overall, 150 patients were included in this study. PD-L1 expression was negative (PD-L1 tumor proportion score <1%) in 89 cases, weak (1-49%) in 42 cases, and strong (≥50%) in 19 cases. mPFS for patients with negative, weak and strong PD-L1 expressions was 23.60, 26.12 and 16.60 months, respectively. The mPFS for strong PD-L1 expression was significantly shorter than that for with weak PD-L1 expression but was not associated with negativity. The same conclusions were shown in subgroup analyses of mutation types and TKI kinds. In addition, Relative to PD-L1-negative patients, resistance to TKIs may be associated with early progression for patients with strong PD-L1 expression.Conclusion: PD-L1 expression in tumor cells influenced the clinical outcomes of patients with advanced NSCLC treated with third-generation EGFR-TKIs. Stronger PD-L1 expression in TKIs-treated patients with advanced first-line EGFR-mutated NSCLC was associated with worse PFS.

Aim: To evaluate real-world treatment patterns, survival and healthcare-resource utilization in US patients with advanced biliary tract cancers (BTC) receiving systemic therapy.Patients & methods: This study used claims data from the Healthcare Integrated Research Database (HIRD®) linked to clinical data from the Cancer Care Quality Program (January 1, 2015-September 30, 2020).Results: Of 413 patients, 84.5% received gemcitabine-based first-line (1L) treatment, 46% received second-line treatment, and 16.5% received third-line (3L) treatment. All-cause mortality was 53% and approximately 70% of patients had ≥1 inpatient visit. The total mean per-patient-per-month all-cause costs were $19,589 for 1L and $33,534 for 3L treatment.Conclusion: Results showed poor survival, significant resource use and high costs as treatment line progresses for patients with advanced BTC.

Ovarian cancer is a leading cause of death from gynecological cancers worldwide. Platinum-based chemotherapy provides the cornerstone of the medical management. In first line and subsequent relapses, maintenance strategies are offered to prolong intervals between lines of chemotherapy. Current maintenance options involve bevacizumab and poly ADP-ribose polymerase inhibitors, but these lines of therapy can only be used once in the disease course. Patients in first or second platinum sensitive relapse after poly ADP-ribose polymerase inhibitors and bevacizumab represent an area of unmet medical need. This academic sponsored, international Phase II randomized trial is evaluating the combination of a therapeutic cancer vaccine (OSE2101) with anti-PD1 (pembrolizumab) as maintenance therapy, in patients with platinum-sensitive recurrence regardless of number of prior lines and no progression after platinum-based chemotherapy.Clinical Trial Registration: NCT04713514 (ClinicalTrials.gov).

Aim: To assess treatment patterns and outcomes in patients with non-del(5q) lower-risk myelodysplastic syndromes. Methods: Patient medical records were reviewed in the USA, Canada (CAN), UK and the EU. Results: Analysis included 119 patients in the USA/CAN (median age, 61.5 years) and 245 patients in the UK/EU (median age, 67.3 years). Most patients received erythropoiesis-stimulating agents (ESAs) as first-line (1L) therapy (USA/CAN: 89.0%; UK/EU: 90.2%). A substantial proportion of 1L erythropoiesis-stimulating agent-treated patients were transfusion dependent before 1L (USA/CAN: 37.1%; UK/EU: 51.2%); a small percentage of these patients achieved transfusion independence during 1L therapy (USA/CAN: 2.8%; UK/EU: 14.4%). Conclusion: These findings highlight an unmet need for more effective treatments among patients with non-del(5q) lower-risk myelodysplastic syndromes.

This is a single arm, open label perioperative trial to assess the feasibility, pharmacokinetics and pharmacodynamics of treatment with safusidenib following biopsy, and prior to surgical resection in patients with IDH1 mutated glioma who have not received radiation therapy or chemotherapy. Fifteen participants will receive treatment in two parts. First, biopsy followed by one cycle (28 days) of safusidenib, an orally available, small molecular inhibitor of mutated IDH1, then maximal safe resection of the tumor (Part A). Second, after recovery from surgery, safusidenib until disease progression or unacceptable toxicity (Part B). This research will enable objective measurement of biological activity of safusidenib in patients with IDH1 mutated glioma. Anti-tumor activity will be assessed by progression free survival and time to next intervention.Clinical Trial Registration: NCT05577416 (ClinicalTrials.gov).

Aim: To explore the knowledge and attitude among oncology patients toward proton radiotherapy. Materials & methods: This cross-sectional study was performed using self-designed questionnaire. Results: Based on 546 valid questionnaires, mean knowledge and attitude scores of 3.4 ± 3.6 (range: 0-12) and 31.1 ± 3.5 (range: 10-50) were observed. Multivariate analysis demonstrated that higher education (p = 0.021), higher monthly income (p = 0.005), and proton radiotherapy history (p < 0.001) were independently associated with higher knowledge scores. Higher knowledge (p = 0.020), older age (p = 0.030), not smoking (p = 0.032) and medication use (p = 0.035) were independently associated with higher attitude scores. Conclusion: Oncology patients have insufficient knowledge and negative attitude toward proton radiotherapy, which might be affected by their age, education, income, proton radiotherapy history, employment, smoking and medication use.

Artificial intelligence (AI) has rapidly advanced in the past years, particularly in medicine for improved diagnostics. In clinical cytogenetics, AI is becoming crucial for analyzing chromosomal abnormalities and improving precision. However, existing software lack learning capabilities from experienced users. AI integration extends to genomic data analysis, personalized medicine and research, but ethical concerns arise. In this article, we discuss the challenges of the full automation in cytogenetic test interpretation and focus on its importance and benefits.

Aim: Vascular endothelial growth factor receptor inhibitors (VEGFRIs) have been common used for recurrent ovarian cancer (ROC), but insufficient high-level evidence on verifying its efficacy and safety. Methods: Randomized controlled trials (RCTs) were searched under eight electronic databases. Stata 14.0 and Review Manager 5.3 were used for data analysis. Certainty of the evidence was assessed using the GRADE profiler. This systematic review (SR) was registered under INPLASY (INPLASY202120019). Conclusion: Totally 23 RCTs involving 2810 patients were included in this SR. Current evidence revealed that VEGFRIs had better efficacy, survival and quality of life in the treatment of ROC. Though VEGFRIs increase some drug-related adverse events (AEs), all the AEs could be manageable in the clinical practice.

The SWI/SNF complex is a chromatin remodeling complex comprised by several proteins such as SMARCA4 or SMARCB1. Mutations in its components can lead to the development of aggressive rhabdoid tumors such as epithelioid sarcoma, malignant rhabdoid tumor or small cell carcinoma of the ovary hypercalcemic type, among others. These malignancies tend to affect young patients and their prognosis is poor given the lack of effective treatments. Characteristically, these tumors are highly infiltrated by TILs, suggesting that some lymphocytes are recognizing tumor antigens. The use of those TILs as a therapeutic strategy is a promising approach worth exploring. Here, we report the clinical protocol of the TILTS study, a Phase II clinical trial assessing personalized adoptive cell therapy with TILs in patients affected by these tumor types.Clinical Trial Registration: 2023-504632-17-00 (www.clinicaltrialsregister.eu) (ClinicalTrials.gov).
