Unveiling the impact of circulating tumor cells: Two decades of discovery and clinical advancements in solid tumors.

Circulating tumor cells (CTCs) enumeration and molecular profiling hold promise in revolutionizing the management of solid tumors. Their understanding has evolved significantly over the past two decades, encompassing pivotal biological discoveries and clinical studies across various malignancies. While for some tumor types, such as breast, prostate, and colorectal cancer, CTCs are ready to enter clinical practice, for others, additional research is required.

Real-World Data on Pembrolizumab for Pretreated Non-Small-Cell Lung Cancer: Clinical Outcome and Relevance of the Lung Immune Prognostic Index.

Background: Pembrolizumab is licensed for the treatment of pre-treated and PD-L1 positive non-small cell lung cancer (NSCLC), but response is heterogeneous. In this context, the Lung Immune Prognostic Index (LIPI) has been proposed as tool to prognosticate outcome.

Objective: To investigate the real-world efficacy and safety of pembrolizumab in pre-treated NSCLC patients and the clinical utility of LIPI for patients' selection.

ADAURA: The Splash of Osimertinib in Adjuvant EGFR-Mutant Non-small Cell Lung Cancer.

The introduction of tyrosine kinase inhibitors (TKI) for the treatment of metastatic non-small cell lung cancer (NSCLC) harbouring sensitizing epidermal growth factor receptor (EGFR) gene mutations revolutionized the diagnostic and treatment algorithm of this subset of patients almost two decades ago. Since then, a number of trials have evaluated the role of TKI therapy in early-stage disease, with encouraging disease-free survival (DFS) results but lack of a survival advantage. ADAURA, a phase III trial evaluating 3 years of adjuvant osimertinib versus placebo in patients harbouring EGFR mutations with completely resected stage IB-IIIA NSCLC, recently reported a profound DFS benefit (hazard ratio 0.
