[Long-term response in advanced pancreatic adenocarcinoma - a case report and literature review].

BACKGROUND

Pancreatic cancer is still considered one of the most aggressive types of cancer and is associated with a very poor prognosis although there have been improvements in diagnostics and chemotherapy regimes in recent years. A cure can only be achieved through complete resection which is only possible when diagnosed at a very early stage, though this is rarely the case. We report on a patient with stage IV adenocarcinoma of the pancreas in which several therapeutically actionable mutations could be detected and discuss new options of targeted therapies.

CASE REPORT

A patient in his 50s was diagnosed with metastatic adenocarcinoma of the pancreas. The patient showed an excellent response to platinum-based chemotherapy with FOLFIRINOX. When a germline mutation in the BRCA-2 gene could be identified, he took part in the POLO-study receiving a maintenance therapy with the PARP-Inhibitor Olaparib. Due to a relapse, 2nd and 3rd line chemotherapy regimens were applied with Gemcitabine combined with Nab-Paclitaxel and later with Erlotinib. Although an activating mutation in the KRAS-gene could be detected as well, the patient rejected further experimental treatment.

CONCLUSION

Identifying predictive factors and specific targetable mutations in patients with advanced pancreatic cancer is needed to be able to apply more individual and specific therapies in order to improve outcomes.
