Sandwich Therapy-Immunotherapy Plus Concurrent Chemoradiotherapy for Advanced Esophagogastric Junction Carcinoma: Report of Two Cases and Literature Review

IntroductionEsophagogastric junction (EGJ) carcinomas develop in the transition zone between the esophagus and stomach. The incidence of EGJ carcinoma has steadily increased over the past few decades. Most patients are first diagnosed at an advanced stage, which renders them ineligible for surgery. Current methods for the treatment of advanced EGJ carcinoma include surgery, chemotherapy, local palliative therapy, and supportive care; however, none of these treatment methods has provided satisfactory therapeutic effects when used alone. Case ReportWe report two cases of patients with EGJ carcinoma who were sequentially treated with immunotherapy plus induction chemotherapy, followed by immunotherapy plus concurrent chemoradiotherapy and maintenance immunotherapy. Both patients achieved extended overall survival times with good quality of life with this new therapeutic approach. ConclusionImmunotherapy plus chemoradiotherapy may therefore be a reasonable option for treatment of selected EGJ carcinoma patients. However, well-designed trials for the acquisition of additional evidence are required to validate the findings in this study.

Automated summary

This article reports two cases of EGJ carcinoma patients who were treated with a new approach combining immunotherapy and chemotherapy. The treatment showed positive outcomes in terms of extended overall survival and improved quality of life. The combination of immunotherapy and chemoradiotherapy may be a viable option for treating selected EGJ carcinoma patients.
