Boosting the Abscopal Effect with Chemoradiotherapy/Immunotherapy Combination in Metastatic Cervical Cancer: A Case Report

The prognosis for patients with distant-organ metastatic cervical cancer (CC) is poor owing to the lack of effective treatment modalities. We present a case of CC with lung metastasis that achieved partial remission of the cervical mass after two cycles of chemotherapy, while the pulmonary nodules remained stable. Moreover, the level of the tumor marker squamous cell carcinoma antigen was slightly higher than before. The patient was recommended to receive pelvic concurrent chemoradiotherapy combined with camrelizumab. Remarkably, after undergoing 16 cycles of immunotherapy, the patient's primary cervical mass and pulmonary nodules were in complete remission, and the tumor marker had returned to normal levels. This inspiring case demonstrates that a combination of chemo-/radio-/immunotherapy can be effective in treating lung metastatic CC and can also enhance the abscopal effect.
