Evaluation of a 'Watch and Wait' Approach for Chemotherapy in Patients with Newly Diagnosed Advanced Non-small Cell Lung Cancer from a Diverse Community Population

A significant proportion of watch and wait patients never receive systemic therapy, predominantly due to a decline in performance status. Patients in the ICT group were younger, had a better performance status and had non-squamous histology compared with the watch and wait group. The overall survival was longer in the patients who received ICT versus watch and wait. The watch and wait strategy is associated with a high risk of missing the opportunity for any chemotherapy and should be judiciously implemented only in carefully selected patients.
