Objectives

Narrative objectives1

To describe the distribution of pretreatment co-occurring genomic alterations in ALK-positive non-small cell lung cancer and to exploratorily evaluate the associations of TP53, RB1, and MTAP alterations with progression-free survival and overall survival after first-line ALK inhibitor therapy. An exploratory composite genomic group based on these alterations will also be evaluated, and supportive external analyses will be performed, primarily focusing on RB1, using available clinico-genomic datasets.

Basic objectives2

Others

Basic objectives -Others

To exploratorily evaluate the associations of TP53, RB1, and MTAP alterations with overall survival after first-line ALK inhibitor therapy. Additional analyses will assess outcomes according to combined TP53/RB1 status, EML4-ALK fusion variant, and the type of first-line ALK inhibitor, as well as the co-occurrence of MTAP loss/deletion with CDKN2A/CDKN2B alterations. Exploratory analyses will also evaluate the prognostic relevance of a composite genomic group based on the major candidate alterations, and supportive analyses using available external clinico-genomic datasets will assess the associations of RB1 and TP53 status with survival outcomes.

Other related information

This is a single-center retrospective observational study of patients with ALK-rearranged non-small cell lung cancer. The study will exploratively evaluate the association between co-occurring genomic alterations other than ALK identified by comprehensive genomic profiling and clinical outcomes of ALK inhibitor therapy. In particular, co-occurring alterations involving TP53, RB1, and MTAP will be evaluated in relation to progression-free survival (PFS) and overall survival (OS).

Eligible patients treated at the study institution during the predefined study period will be retrospectively identified. No random or case-control sampling will be performed, and consecutively identifiable eligible patients with evaluable data will be included. No additional examination, treatment, or intervention will be performed for research purposes.

Supportive analyses using available external clinical genomic datasets will also be conducted to evaluate the association between major candidate genomic alterations and prognosis.
