Gemcitabine remains the mainstay of palliative chemotherapy for those patients with unresectable or metastatic pancreatic cancer. Objective radiological responses to gemcitabine are rare and reported median survival is only about six months. New therapeutic concepts and strategies are needed in order to improve those dismal statistics.
We report here a case of a patient with metastatic pancreatic cancer responding to a third-line therapy with combination of mitomycin C and capecitabine. Interestingly, the patient had a strong family history of breast cancer and tested positive to germline BRCA2 mutation.
We feel that this is of interest because of preclinical reports of increased sensitivity of pancreatic cells carrying BRCA2 mutations to DNA-intercalating agents such as mitomycin C. Further research and clinical trials are warranted to support this novel concept.
对于无法切除或发生转移的胰腺癌患者,吉西他滨仍然是姑息化疗的主要药物。吉西他滨的客观影像学反应罕见,报告的中位生存期仅约6个月。需要新的治疗理念和策略来改善这些不佳的数据。
我们在此报告一例转移性胰腺癌患者,对丝裂霉素C和卡培他滨联合的三线治疗有反应。有趣的是,该患者有很强的乳腺癌家族史,并且种系BRCA2突变检测呈阳性。
我们认为这很有意义,因为临床前报告显示携带BRCA2突变的胰腺细胞对丝裂霉素C等DNA嵌入剂的敏感性增加。有必要进行进一步的研究和临床试验来支持这一新概念。
