Abstrakt: Background: Recently, we could show that the co-mutations of KRAS + KEAP1 , STK11 + KEAP1 and KRAS + STK11 + KEAP1 lead to a significantly shorter median overall survival (mOS) across treatments by analyzing multiple datasets. TP53 , a tumor suppressor gene, plays a crucial role in regulating cell cycle progression. Its mutations occur in approximately 40-50% of non-small lung cancer (NSCLC). Co-occurrence of all four mentioned mutations has been a matter of debate for years. The aim of this study was to assess the distribution of these four mutations and the influence of the different co-mutational patterns on survival.
Methods: We present a comparative bioinformatic analysis and refer to data of 4,109 patients with lung adenocarcinoma (LUAD).
Results: Most of the mutations within the LUAD belong to TP53 -only (29.0%), quadruple-negative (25.9%) and KRAS -only (13.4%). Whereas TP53 -mutations seem to have protective effects in the context of further KEAP1 - and KRAS + KEAP1 - alterations (improved mOS), their role seems contrary if acquired in an already existing combination of mutations as KRAS + STK11 , KRAS + STK11 + KEAP1 and STK1 + KEAP1 . TP53 co-mutationshad a negative influence on KRAS -only mutated LUAD (mOS reduced significantly by more than 30%).
Discussion: These data underline the need for complex mutational testing to estimate prognosis more accurately in patients with advanced LUAD.
