Tumor Discovery Anti-PD1 for advanced pancreatic cancer
A Fortunately, immunotherapy has gradually transformed
the therapeutic landscape for various solid tumors, such
as renal cell cancer, lung cancer, melanoma, and others. In
the field of immunotherapy, many clinical trials are being
performed to test the efficacy of immunotherapy in PC, for
example, the application of adoptive cell transfer, cancer
vaccines, ICI, and combinations with molecular targeted
agents or chemoradiotherapy. It is reported that PD-L1
expression is a prognostic response to immunotherapy in
PC, so anti-PD-1 immunotherapy holds promise in the
B future treatment of PC. In addition, the combination of
cytotoxic drugs and immunotherapy seems to result in a
synergistic effect .
[12]
In this case report, we present our experiences
in treating a PC patient using surgical resection,
chemotherapy, molecular targeted medicine, and anti-PD1
immunotherapy. The combined treatment modalities
turned out to be successful in extending the patient’s
survival time to more than 6 years since diagnosis.
That being said, the application of immunotherapy in
C
combination with different therapeutic strategies might
offer a favorable treatment option for PC patients.
However, the current treatment modalities for the
treatment-associated toxicity of immunotherapy-based
approaches are limited. Even though immunotherapy
can significantly improve cancer pain and provide an
overall favorable clinical and survival benefit, the use
of immunotherapy for PC still needs to be further
