Metastatic pancreatic and lung cancer patient in complete remission following immunotherapy: A case report and review of literature Martínez Galán, Joaquina Jiménez Luna, Cristina Rodríguez, Isabel Maza, Elisabeth García Collado, Carlos Rodríguez Fernández, Antonio López Hidalgo, Javier Luis Caba Pérez, Octavio Pancreatic ductal adenocarcinoma Lung cancer; Immunotherapy Pembrolizumab Programmed cell death protein- 1 Case report María Zambrano postdoctoral fellowship funded by the Spanish Ministry of Universities and Next Generation European Union. The lack of specific symptoms in patients and the absence of a reliable and well-stablished diagnostic method, makes advanced pancreatic ductal adenocarcinoma (PDAC) the most common clinical appearance of pancreatic cancer cases. In these circumstances, surgical resection, the only curative approach for this malignancy, is unaffordable, leading to very low survival outcomes. Immunotherapy is a recent approach that has been studied in many cancer types showing encouraging results, but it has not been sufficiently investigated in PDAC. We report the case of a patient with unresectable PDAC that progressed to metastasis after treatment with chemoradiation, who showed an outstanding response to immuno- therapy with pembrolizumab, achieving a complete remission within a few months, which was maintained until the end of treatment. Currently, the patient continues in disease-free state. 2025-03-13T12:50:12Z 2025-03-13T12:50:12Z 2024-05-15 journal article Martínez-Galán, J., Jiménez-Luna, C., Rodriguez, I., Maza, E., García-Collado, C., Rodríguez-Fernández, A., López-Hidalgo, J.
