Response to a third-line mitomycin C (MMC)-based chemotherapy in a patient with metastatic pancreatic adenocarcinoma carrying germline BRCA2 mutation.

CONTEXT: 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.

CASE REPORT: 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.

CONCLUSION

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.
