RESUMEN
The discovery of KRAS mutations, particularly the KRASG12C variant, has been a milestone in understanding the molecular underpinnings of non-small cell lung cancer (NSCLC). These mutations are associated with aggressive tumor behavior and resistance to conventional therapies, highlighting the urgent need for targeted interventions. In this comprehensive review, we analyze the advancements in KRAS G12C inhibitors for the treatment of non-small cell lung cancer. Literature search is made from PubMed, Medline ASCO and ESMO Annual Meetings abstracts by using the following search keywords: "sotorasib", "adagrasib", "divarasib" and "KRAS G12C inhibitors." The last search was on 5 June 2024. This review highlights the importance of pharmacokinetics, pharmacodynamics and potential adverse effects for treating individual patients and ensuring the best outcomes. Additionally, the review discusses research identifying biomarkers that can predict therapy responses and mentions the combination strategies to overcome resistance. Results of the studies and ongoing clinical trials are also briefly summarized in this review. KRASG12C inhibitors sotorasib, adagrasib and the newer divarasib, has revolutionized treating patients harboring this mutation. Ongoing studies and future clinical trials will refine our understandings with the ultimate goal of improving survival and quality of life for patients with this challenging disease.

RESUMEN
OBJECTIVE: The objective of this article is to review the efficacy, safety, and evidence for current use and potential future uses of immune-checkpoint inhibitors (ICIs) in the management of resectable non-small cell lung cancer (NSCLC). DATA SOURCES: A literature review was carried out through PubMed to identify completed and ongoing clinical trials evaluating the use, efficacy, and safety of ICIs in the management of resectable NSCLC. DATA SUMMARY: To date, four phase 3 trials have emerged that have changed our treatment practice concerning the utilization of ICIs during the adjuvant and neoadjuvant settings. The IMpower010 and KEYNOTE-091 trials examined the application of adjuvant atezolizumab and pembrolizumab, respectively, following surgical resection and adjuvant chemotherapy. In the CheckMate 816 trial, the combination of nivolumab and chemotherapy as a neoadjuvant therapy received approval for patients with resectable NSCLC. Also, for patients with resectable NSCLC, the use of a pembrolizumab and chemotherapy combination as a perioperative therapy received approval based on the results of the KEYNOTE-671 trial. Apart from these trials, there are numerous phase 2 and phase 3 trials, some of which have been published while others are still in progress. CONCLUSION: Despite the promising outcomes from these trials there remain several unanswered questions. In this review, we will assess clinical trials involving adjuvant, neoadjuvant, and perioperative ICIs, aiming to address the unresolved questions related to these therapeutic approaches.
