Summary
Brief summary (as posted)
PD1, as an immune checkpoint inhibitor, has provided a new therapeutic approach for patients with cancer, including patients. Although immunotherapy has proven effective, most patients do not benefit from it because of a large proportion which developing primary and acquired resistance. However, there is still a lack of accurate and effective molecular biomarkers to accurately evaluate the drug resistance of patients treated with immune checkpoint inhibitors (ICI), so as to maximize the therapeutic effect in patients. Chromosomal instability (CIN) is one of the most prominent and common characteristics of solid tumors, accelerating the development of anti-cancer drug resistance, often leading to treatment failure and disease recurrence, which limits the effectiveness of most current treatments. Hence the aim of this study is to evaluate dynamic CIN continuously monitored in the blood of patients with lung cancer treated with ICIs with Ultrasensitive Chromosomal Aneuploidy Detection (UCAD) to establish a new molecular immune resistance evaluation index. Further, the correlation between the evolution of tumor cloning and ICI resistance in patients during treatment was analyzed based on the results of dynamic CIN detection. This not only evaluate the efficacy of the ICI treatment in real-time, but also enables better understanding and overcoming the resistance mechanism of immunotherapy in the future.

- label
- patient with PD1 antibody treatment
- description
- Investigators will detect cfDNA CIN of lung cancer patients 1day (Day 0) before treatment with PD1 antibody, then Day 22 and Day 64 after treatment with PD1 antibody, as well as at the time of disease progression confirmed. The correlation of CIN and drug resistance to PD1 antibody was analyzed.

- Diagnostic Test: the level of plasma cfDNA CINs
Primary outcomes (1)
- measure
- the concordance bettwen CINs and treatment outcomes The concordance between CINs and treatment outcomes
- timeFrame
- through study completion, an average of 3 months
- description
- According to the correlation analysis between the patient's clinical drug resistance and CIN detected using UCAD, the stratified cutoff value interval of the patient was found, which was divided into four treatment outcomes based on CIN assessment : significant efficacy, primary drug resistance, acquired drug resistance and possible super progress.
