Stage III NSCLC treatment options: too many choices

Abstract

Stage III nonsmall cell lung cancer (NSCLC) represents a wide range of tumour (T1 to T4) and nodal (N0 to N3) components, requiring variable management and a multidisciplinary approach. Recent advancements in minimally invasive techniques, molecular biology and novel drug discoveries have accelerated the refinement of stage III NSCLC management. The latest developments in staging include the forthcoming update of the nodal component in the 9th TNM (tumour–node–metastasis) edition, which emphasises the critical role for endobronchial ultrasonography in mediastinal staging. Recent treatment developments include the use of immunotherapy and targeted molecular therapy in both the neoadjuvant and adjuvant setting, either in combination with other modalities or used alone as consolidation. Surgical and radiotherapy advancements have further enhanced patient outcomes. These developments have significantly improved the prognosis for patients with stage III NSCLC. Fast-changing recommendations have also brought about a challenge, with clinicians facing a number of options to choose from. Therefore, a multimodal approach by a multidisciplinary team has become even more crucial in managing stage III NSCLC.
