Successful replacement for recurrent nasopharyngeal carcinoma with cholecystitis induced by PD-1 antibody: a case report.
The occurrence of immune-related cholecystitis and the subsequent immunotherapy re-challenge has been rarely reported. A patient diagnosed with recurrent nasopharyngeal carcinoma, developed immune-related cholecystitis after the sixth and eighth cycles of camrelizumab respectively. The patient's symptoms and laboratory test results showed improvement after conservative treatment. Then we chose zimberelimab, a fully humanized PD-1 antibody, as a replacement for camrelizumab in maintenance therapy and successfully completed 37 cycles of zimberelimab (240 mg every 2 weeks per cycle). Surprisingly, the patient experienced no immune-related adverse event and remained in complete remission with a progression-free survival of 28.8 months. The use of Zimberelimab as rechallenge immunotherapy may be an optional choice after managing immune-related cholecystitis induced by other PD-1 antibodies.
期刊介绍：
Many aspects of the immune system and mechanisms of immunomodulatory therapies remain to be elucidated in order to exploit fully the emerging opportunities. Those involved in the research and clinical applications of immunotherapy are challenged by the huge and intricate volumes of knowledge arising from this fast-evolving field. The journal Immunotherapy offers the scientific community an interdisciplinary forum, providing them with information on the most recent advances of various aspects of immunotherapies, in a concise format to aid navigation of this complex field.
Immunotherapy delivers essential information in concise, at-a-glance article formats. Key advances in the field are reported and analyzed by international experts, providing an authoritative but accessible forum for this vitally important area of research. Unsolicited article proposals are welcomed and authors are required to comply fully with the journal''s Disclosure & Conflict of Interest Policy as well as major publishing guidelines, including ICMJE and GPP3.
