RESUMO

BACKGROUND: To compare the clinicopathological characteristics of nonmetastatic breast cancer patients with and without BRCA variations and to investigate the impact of BRCA variations on prognosis. METHODS: This retrospective single-center study involved an analysis of 938 patients with localized or locally advanced breast cancer who underwent BRCA variation testing. The patients were divided into three groups: 757 were without BRCA variation, 64 were with BRCA1 variation, and 117 were with BRCA2 variation. RESULTS: In patients with BRCA1 variation, the Ki67, grade, and frequency of triple-negative breast cancer were significantly higher than in patients without BRCA variation and with BRCA2 variation. The 5-year disease-free survival in patients with BRCA1 variation was significantly worse than the other two groups (without BRCA, BRCA1, and BRCA2; 87.7%, 69.9%, and 95.3%, respectively, p = 0.049). Multivariate analysis detected no significant difference between groups. The pathological complete response rates with neoadjuvant therapy were significantly better in patients with BRCA variations than those without BRCA variations (49.2% vs. 29.6%, p = 0.024). CONCLUSION: Patients with BRCA1 variation had more aggressive tumor characteristics, such as higher Ki67 and higher grade. Also, triple-negative breast cancer was more common. The presence of BRCA1 variation may worsen survival outcomes. Neoadjuvant treatment responses of patients with BRCA variations were significantly better, and neoadjuvant treatment may contribute to survival outcomes in nonmetastatic patients with BRCA variations.

RESUMO

This study addresses the gap in understanding the prognostic relevance of hypoxia-inducible factor-1 alpha (HIF-1 alpha) expression in metastatic cervical squamous cell carcinoma (SCC) patients undergoing anti-vascular endothelial growth factor (VEGF)-based therapy. A retrospective multicenter study (n = 34) explored HIF-1 alpha expression via immunohistochemistry in patients treated with platinum chemotherapy and bevacizumab. Median progression-free survival (PFS) was significantly lower in the HIF-1 alpha low score group compared to the high score group (4.9 vs 12.9 months, P = 0.014). Similarly, the median overall survival (OS) was significantly reduced in the HIF-1 alpha low score group (8.3 vs 20.4 months, P = 0.006). This study, the first of its kind, highlights the prognostic significance of HIF-1 alpha expression in metastatic cervical SCC patients treated with bevacizumab-based therapy.

RESUMO

Our aim was to assess the efficacy of adjuvant programmed cell death protein-1 (PD-1) inhibitors and compare the other adjuvant treatments in patients with surgically resected stage III or IV acral melanoma. This study is a multicenter, retrospective analysis. We included 114 patients with stage III or IV acral malignant melanoma who underwent surgery within the past 10 years. We analyzed the effect of adjuvant programmed cell death protein-1 inhibitors on disease-free survival (DFS). The mean follow-up was 40 months, during which 69 (59.5%) patients experienced recurrence. Among the participants, 64 (56.1%) received systemic adjuvant therapy. Specifically, 48.4% received anti-PD-1 therapy, 29.7% received interferon, 14.1% received tezozolomide, and 7.8% received B-Raf proto-oncogene/mitogen-activated protein kinase inhibitors. Patients who received adjuvant therapy had a median DFS of 24 (10.9-37.2) months, whereas those who did not receive adjuvant therapy had a median DFS of 15 (9.8-20.2) months. Multivariate analysis for DFS revealed that the receipt of adjuvant therapy and lymph node metastasis stage were independent significant parameters ( P = 0.021, P = 0.018, respectively). No statistically significant difference was observed for DFS between programmed cell death protein-1 inhibitor treatment and other adjuvant treatments. Regarding overall survival (OS), patients who received adjuvant treatment had a median OS of 71 (30.4-111.7) months, whereas those who did not receive adjuvant treatment had a median OS of 38 (16.7-59.3; P = 0.023) months. In addition, there were no significant differences in OS observed between various adjuvant treatment agents ( P = 0.122). In our study, we have shown that adjuvant therapy had a positive effect on both DFS and OS in patients with stages III-IV acral melanoma who underwent curative intent surgery. Notably, we found no significant differences between anti-PD-1 therapy and other adjuvant therapies.
