We present the first case of isolated peritoneal carcinomatosis (PC) from prostate cancer carrying a previously unreported pathogenic BRCA2 mutation without other organ involvement. CT showed PC with no extra-peritoneal metastases. Treatment included neoadjuvant chemotherapy, cytoreductive surgery/hyperthermic intraperitoneal chemotherapy (CRS/HIPEC), and adjuvant chemotherapy. Patient is disease-free after 30-months. Germline genetic testing showed BRCA2 c.1813dupA (p.I605Nfs*11) mutation, reported in breast and ovarian cancers. Tumor genomic testing also revealed TMPRSS2, TBX3, and TP53 mutations. Given the comparable presentation and BRCA-mutation profile to ovarian cancer, BRCA2 mutations may contribute to disease phenotypes. CRS/HIPEC may provide long-term outcomes for this unique metastatic pattern.
我们报告了首例前列腺癌孤立性腹膜癌(PC)病例,该病例携带以前未报道的致病性 BRCA2 突变,没有其他器官受累。CT 显示 PC 无腹膜外转移。治疗包括新辅助化疗、细胞减灭术/腹腔热灌注化疗(CRS/HIPEC)和辅助化疗。患者在 30 个月后无疾病。种系基因检测显示 BRCA2 c.1813dupA(p.I605Nfs*11)突变,该突变与乳腺癌和卵巢癌有关。肿瘤基因组检测还显示 TMPRSS2、TBX3 和 TP53 突变。鉴于与卵巢癌相似的表现和 BRCA 突变特征,BRCA2 突变可能导致疾病表型。CRS/HIPEC 可能为这种独特的转移模式提供长期疗效。
