Abstract
BACKGROUND: Pancreatic cancer (PC) is a leading cause of cancer-related death, given its poor prognosis and the limited benefits of traditional therapies. As tumors become more genetically disorganized as they progress, genetic mutations might become new markers for us to predict their behavior. Nowadays, many inhibitors can selectively target gene products as a form of targeted therapy, with some showing promise as treatment for various types of cancer. CASE SUMMARY: We describe a rare case of a PC patient with long-term survival of more than 8 yr. The patient was diagnosed with pancreatic ductal adenocarcinoma (PDAC) with BAP1 and PIK3CA gene mutations and Raf1 fusion and achieved partial response twice after treatment with apatinib in combination with chemotherapy. CONCLUSION: BAP1, PIK3CA mutations, and Raf1 fusion are rare in PDAC. Patients with these three gene alterations of PDAC may achieve long-term survival with apatinib. Further research in other contexts is needed to determine whether apatinib has ideal efficacy for PC treatment.
