Conditions

Esophageal Cancer

Brief summary

This study is a retrospective study of clinical specimens. The study subjects were patients with esophageal cancer who received immunotherapy. Tumor tissue specimens surgically removed from patients before treatment will be collected primarily. In situ immunohistochemistry and multicolor immunofluorescence will be performed. We hypothesize that there are differences in lipid metabolism-related proteins in tumor tissues and immune cells in the preexisting tumor microenvironment in patients with esophageal cancer prior to immunotherapy, and that there is a link between such differences and the efficacy of immunotherapy.

CR、PR、SD、PD2018-2022CR:All target lesions disappear and the short diameter of all pathologic lymph nodes (both target and non-target nodes) must be reduced to \<10 mm. PR:At least 30% reduction in the sum of target lesion diameters from baseline levels SD:A relative increase in diameter sum of at least 20% (or the baseline value if the baseline measurement is minimal), referenced to the minimum of the sum of the diameters of all measured target lesions throughout the course of the experimental study; in addition to this, an increase in the absolute value of diameter sum of at least 5 mm must be met (the presence of one or more new lesions is also considered to be disease progression). Translated with www.DeepL.com/Translator (free version) PD:The target lesion did not decrease to the level of PR, nor did it increase to the level of PD, and in between, the minimum value of the sum of the diameters can be used as a reference for the study.
