Advanced pancreatic cancer treated with camrelizumab combined with apatinib: A case report.

Background: The 5-year survival rate for patients with pancreatic cancer (PC) is 4%-12%. Surgery is the only treatment that offers curative potential, but only 15%-20% of patients are eligible for surgery. PC is prone to recurrence and metastasis, and the antitumor effect of chemotherapy is notably limited.

Case Summary: Histopathological analysis of a 53-year-old female PC patient who underwent Whipple surgery revealed poorly differentiated tumor cells infiltrating nerves, lymphatics, and blood vessels. The patient received two different first-line chemotherapy regimens consecutively; however, both regimens struggled to control disease progression. During this period, the patient underwent liver metastasis ablation surgery, liver abscess, and stereotactic body radiotherapy. With the addition of camrelizumab to the modified FOLFIRINOX regimen, tumor control was achieved. The patient subsequently refused to continue chemotherapy, and the antitumor regimen was changed to a combination of camrelizumab and apatinib. After patients received a combination of immunotherapy and targeted therapy, the length of hospital stay was significantly reduced. Furthermore, all side effects were within acceptable limits, leading to an improved quality of life and prolonged progression-free survival. Unfortunately, the pain associated with cancer, coupled with the side effects of opioid analgesics, has led the patient to reject all available anticancer treatment options. Approximately one month after camrelizumab and apatinib were discontinued without medical authorization, the PC recurred and rapidly progressed to widespread metastasis, ultimately leading to the patient's death approximately one month later. The overall survival was 2 years.

Conclusion: Immunotherapy and targeted therapy have the potential to increase both the quality of life and survival time of PC patients, particularly those whose tumor progression is not effectively controlled by chemotherapy alone. Nevertheless, further clinical trials are necessary to validate these findings.
