RESUMO

OBJECTIVE: To investigate the role of BRCA1/2 mutations in early ovarian cancer (eOC) (International Federation of Gynecology and Obstetrics FIGO 2014 stage I-II), and its impact on prognosis after relapse. METHODS: In this multicenter retrospective study, clinical and survival data from high-grade serous (HGS)-eOC patients at presentation and recurrence were compared according to BRCA status: BRCA-mutated (BRCAmut) vs. BRCA wild-type (BRCAwt). RESULTS: Among 191 HGS-eOC patients, 89 were BRCAmut and 102 BRCAwt. There was no significant difference according to the BRCA status in terms of Progression-Free Survival (PFS). A longer Overall Survival (OS) was found in BRCAmut patients. Stage I patients had significantly improved PFS vs stage II, regardless of BRCA status. At multivariate analysis, stage at diagnosis was the only variable with a significant effect on PFS. No factors were significantly relevant on OS, albeit younger age and BRCA mutation showed a slight impact. Post-Recurrence Survival (PRS) in the BRCAmut population was significantly improved compared with BRCAwt. At multivariate analysis, Secondary Cytoreductive Surgery was the strongest predictor for longer PRS, followed by PARPi maintenance at recurrence. CONCLUSIONS: BRCA-status is not a prognostic factor in early ovarian cancer regarding PFS. However, our data suggest a better prognosis after relapse in BRCAm population.

RESUMO

Risk-reducing surgery (RRS) is recommended in BRCA-mutated carriers because of their increased risk of developing ovarian cancer, while its role is still discussed for women harboring mutations in non-BRCA homologous repair genes. The aim of this study was to retrospectively evaluate the occurrence of pathological findings in a high-risk population undergoing RRS in San Matteo Hospital, Pavia between 2012 and 2022, and correlate their genetic and clinical outcomes, comparing them with a control group. The final cohort of 190 patients included 85 BRCA1, 63 BRCA2, 11 CHEK2, 7 PALB2, 4 ATM, 1 ERCC5, 1 RAD51C, 1 CDH1, 1 MEN1, 1 MLH1 gene mutation carriers and 15 patients with no known mutation but with strong familial risk. Occult invasive serous carcinoma (HGSC) and serous tubal intraepithelial carcinoma (STIC) were diagnosed in 12 (6.3%) women, all of them BRCA carriers. No neoplastic lesion was diagnosed in the non-BRCA group, in women with familial risk, or in the control group. Oral contraceptive use and age ≤45 at surgery were both found to be favorable factors. While p53 signature and serous tubal intraepithelial lesion (STIL) were also seen in the control group and in non-BRCA carriers, STIC and HGSC were only found in BRCA1/2 mutation carriers.

RESUMO

BACKGROUND: The role of surveillance after surgery for stage IA-C grade 2 (G2) or grade 3 (G3) immature teratomas (ITs) is controversial with many guidelines advocating adjuvant chemotherapy. Here, we investigate the safety of surveillance in stage IA-C G1-3 ITs. METHODS: Clinicopathological data were analysed on postpubertal patients with stage I pure ITs in Multicenter Italian Trials in Ovarian Cancer centres and at Charing Cross Hospital, UK, between January 1985 and January 2018. RESULTS: Of 108 stage I patients, 66 (61.1%), 3 (2.8%) and 39 (36.1%) were International Federation of Gynecology and Obstetrics IA, IB, IC, respectively, with 31 (28.7%), 41 (38%) and 36 (33.3%) having grade 1 (G1), 2 and 3 disease, respectively. After surgery, 27 patients (25%) had adjuvant chemotherapy and 81 (75%) surveillance. There was no significant increase in the risk of malignant (G2-3 IT) relapse (9/81 vs 2/27; p = 0.72) or in disease-free survival (DFS) or overall survival in the surveillance vs chemotherapy groups. The median time to relapse was 17.8 months (range: 3-47) with no significant difference between surveillance or chemotherapy groups. The median follow-up was 64.3 months (Interquartile range (IQR) 22.2-101.7). Chemotherapy induced cures in all except for one patient who did not follow the surveillance protocol due to pregnancy and died of disease. Univariate and multivariate analyses revealed that only tumour grade (hazard ratio [HR] = 3.11; p = 0.02) and complete surgical staging (HR = 0.2; p = 0.01) were independent prognostic factors for decreased DFS. CONCLUSION: The present study suggests that in the adult setting careful surveillance appears to be an acceptable alternative to adjuvant chemotherapy for stage IA-C ITs of any grade, properly staged and with negative postoperative tumour markers.
