Aim: To assess the relationship between [F]FDG PET/CT, breast cancer gene (BRCA) status, and their prognostic role in patients with ductal breast cancer (DBC).
Methods: Forty-one women were included. PET/CT semiquantitative parameters such as standardized uptake value (SUV) body weight max (SUVmax), SUV body weight mean (SUVmean), SUV lean body mass (SUVlbm), SUV body surface area (SUVbsa), metabolic tumor volume (MTV), total lesion glycolysis (TLG), ratio SUVmax/blood-pool (S-BP), and ratio SUVmax/liver (S-L) were also extracted. The relationship between these parameters, BRCA, and other clinicopathological features were evaluated. Kaplan-Meier, univariate, and multivariate analyses were performed to find independent prognosticators for progression free (PFS) and overall survival (OS).
Results: Significant positive correlations between BRCA status and SUVmax (-value 0.025), SUVlbm (-value 0.016), and SUVbsa (-value 0.018) were reported. Mean PFS was 53.90 months with relapse/progression of disease occurring in nine (22.0%) patients; mean OS was 57.48 months with death occurring in two (4.9%) patients. Survival curves revealed TLG, MTV, and BRCA status as prognosticator for PFS; BRCA was also a prognosticator for OS. Univariate and multivariate analyses did not confirm such insights.
Conclusion: We reported a correlation between some PET/CT parameters and BRCA status; some insights on their prognostic role have been underlined.

Division of Medical Oncology A Policlinico Umberto I Rome Italy.
Background: We present a systematic review and meta-analysis of randomized clinical trials (RCTs) with PARPi either as monotherapy or in combination with an androgen receptor-targeted agent (ARTA) in first- and second-line settings.
Methods: Primary endpoints are radiographic progression free survival (rPFS) and overall survival (OS) in patients with mCRPC and either unselected, homologous recombination repair wild-type (HRR-), homologous recombination repair mutated (HRR+) or with BRCA1, BRCA2, or ATM mutation. The effect of PARPi + ARTA in the second-line setting is also explored.

Background And Purpose: Despite advancements in genetic testing and expanded eligibility criteria, underutilisation of germline testing for pathogenic variants in BRCA1 and BRCA2 (BRCA) remains evident among breast cancer (BC) patients. This observational cohort study presents real-world data on BRCA testing within the context of clinical practice challenges, including incomplete family history and under-referral.
Material And Methods: From the Danish Breast Cancer Group (DBCG) clinical database, we included 65,117 females with unilateral stage I-III BC diagnosed in 2000-2017, of whom 9,125 (14%) were BRCA tested.

Objective: To compare the effects of different treatment modes containing PARPis and traditional treatment modes on the survival of patients with recurrent ovarian cancer.
Methods: From December 2012 to December 2023, 131 recurrent ovarian cancer patients were screened. The patients were followed up retrospectively, and the relevant data was collected and analyzed.

Objective: The current clinical data regarding the re-administration of PARPi maintenance therapy in platinum sensitive recurrent ovarian cancer (PSROC) is limited. This study aims to investigate the efficacy and associated factors of PARPi re-maintenance therapy in PSROC patients in China.
Methods: In this study, there were 201 patients with PSROC who had received maintenance therapy previously and achieved complete or partial response after platinum-based chemotherapy upon recurrence.

Unlabelled: Our previous study on breast cancer BRCA carriers disclosed a high local recurrence (LR) rate in patients who underwent skin sparing (SSM) or nipple sparing mastectomy (NSM) without postoperative radiation therapy (RT), compared to breast conservation surgery or mastectomy with RT. The current study compares the LR rates in BRCA versus non BRCA carriers after SSM/NSM in relation the receipt of RT.
Methods: The study was approved by the institutional ethics committee.
