Predictive immunotherapeutic markers of adenocarcinomas and adenosquamous carcinoma of the cervix

Adenocarcinoma and adenosquamous carcinoma of the cervix together account for up to 20% of all cervical cancers. These histologic subtypes are characterized by a worse prognosis compared with squamous cell cancer of the same grade and have specific epidemiologic, morphologic and molecular features. Despite fundamental differences, therapeutic approaches for cervical cancer are similar regardless of tumor histology. This article discusses promising companion diagnostic markers for cervical cancer treatment, including MSI, PD-L1 and TIL’s, that may find application in the therapy of prognostically unfavorable subtypes of cervical cancer. The literature review revealed that despite the low frequency of immunotherapy markers among adenocarcinomas and adenosquamous carcinomas of the cervix, analyzing them will allow us to identify a group of patients who will benefit most from immunotherapy, a key step towards improving treatment outcomes.
