简要总结
Lymphoepithelioma-like carcinoma (LELC) may benefit from immunocheckpoint inhibitor therapy. Although target antibody drugs for PD-1 and PD-L1 have achieved good results in immunotherapy of many malignant tumors, there is still a lack of corresponding clinical research reports on whether LELC treatment can benefit. Therefore, this study intends to adopt the basket research model , to explore the application of anti-procedural death receptor 1 (PD-1) monoclonal antibody in patients with advanced LELC after the failure of first-line standard treatment . Further explore the relationship between tumor and body immunity, tumor microenvironment and curative effect, and find stable biomarkers, so as to screen out the superior population of tumor immunotherapy.

研究组 & 干预措施
PD-1 monoclonal antibody
Experimental
干预措施: PD-1 monoclonal antibody (Drug)
结局指标
主要结局
Progress-free survival
时间窗: Through study completion, an average of 9 weeks
The time from enrollment to the occurrence of tumor development (in any aspect) or death (for any reason). For subjects without disease progression or death, the date of the last imaging evaluation is the date of censorship. Subjects who did not undergo imaging evaluation or no death record after baseline were deleted based on the enrollment date.
次要结局
- Objective response rate(Through study completion，an average of 9 weeks)
- Time to initial response(Through study completion，an average of 9 weeks)
- Overall survival(Through study completion， an average of 90 days)
- Duration of response(Through study completion，an average of 9 weeks)
- Tumor immune microenvironment(Baseline)
