ABSTRACT

PURPOSE: We evaluated the prevalence of homologous recombination deficiencies (HRD) to determine the efficacy of different techniques and clinical characteristics of patients. METHODS: This retrospective study included patients with metastatic prostate cancer who underwent molecular testing at our hospital between 2016 and 2022. We used tumor tissue, ctDNA, and lymphocytes for somatic or germline testing. We analyzed the clinical characteristics and survival outcomes. RESULTS: 144 patients were tested (113 somatic, 21 germline, and 10 both). Technical issues prevented the analysis of 23 prostatic samples (18.7%). 12 (8.3%) patients had HRD. BRCA2 was the most frequent mutation (66.7%). Patients with HRD were younger (57.5 years). Patients with BRCA mutations had poorer survival (31.9 vs 56.3 months, p = 0.048). CONCLUSION: In our institution, 8.3% of the patients had HRD. Tumor tissue analysis failed in 18.7% of tests. ctDNA analysis is an alternative detection method. BRCA mutations are correlated with poor prognosis.

ABSTRACT

PURPOSE: To describe the incidences of hypogonadism, hypertension, and dyslipidaemia in patients with stage 1 seminoma (S1S) testicular cancer (TC) treated with a risk-adapted strategy. METHODS: A retrospective analysis from 2000 to 2020 was conducted. Active surveillance (AS), carboplatin one cycle, and carboplatin two cycles were offered according to risk factors. Cumulative incidences and relapse-free survival (RFS) were estimated. RESULTS: Of the 145 patients, 8 (5.4%) were excluded due to bilateral TC or hypogonadism at diagnosis. Median follow-up time was 8.2 years. Eighty-four, 30, and 33 patients were treated with AS, carboplatin one cycle, and carboplatin two cycles, respectively. In the overall population, the 5-year and 10-year cumulative incidences were 1.6% and 5.3% for hypogonadism; 2.0% and 8.6% for hypertension; and 12.4% and 25.1% for dyslipidaemia. No statistically significant differences were found in the incidences among the three adjuvant strategies. Five-year and 10-year RFS were 85.9% and 83.3% for AS; 92.4% and 84.0% for carboplatin one cycle; and 96.7% at both times for carboplatin two cycles. CONCLUSION: There were no statistically differences in cumulative incidences of hypogonadism, hypertension, and dyslipidaemia in S1S patients treated with a risk-adapted strategy.
