Adjuvant immunotherapy fails to improve survival in ypStage I esophageal cancer after neoadjuvant immunochemotherapy.

ABSTRACT:

Backgrounds

While adjuvant immunotherapy (AIT) is recommended for non-pathological complete response (non-pCR) patients, its role in ypStage I esophageal cancer (EC) patients with low tumor burden remains unclear. The study aims to evaluate the necessity of AIT for esophageal cancer patients achieving ypStage I following neoadjuvant immunochemotherapy (NICT) and surgery.

Methods

This retrospective study analyzed 157 ypStage I (ypT0-2N0M0) EC patients treated with NICT followed by surgery in Sun Yat-sen University Cancer Center between 2019 and 2024. Propensity score matching (PSM) and inverse probability of treatment weighting (IPTW) adjusted for baseline imbalances between the none adjuvant therapy (NAT, n = 121)  group and AIT (n = 36) group.
