Introduction: Chemo-immunotherapy combinations have revolutionized our treatment algorithm with respect to naïve advanced NSCLC; however, given the great number of developed and approved combinations, the question arises as to which combinations provide the best efficacy and safety., Areas Covered: This review assesses and discusses the available data concerning chemo-immunotherapy combinations in the treatment of naïve advanced NSCLC, as well as presenting the most promising data involving combinations currently under investigation., Expert Opinion: Pembrolizumab-containing chemo-immunotherapy combinations are associated with the most mature data available and presently represent the standard treatment in clinical practice in naïve advanced NSCLC-affected patients. The nivolumab plus ipilimumab plus short-course chemotherapy combination, more recently approved by regulatory agencies, is an appealing alternative, thanks to the reduced rate of grade 3-5 TRAEs and the limited chemotherapy administration. The new chemo-immunotherapy combinations currently under investigation will help us to better identify both the best immune checkpoints to target and the most effective combinations to administer.

Introduction : Even with the currently recommended chemotherapeutic and immunotherapeutic treatment, the five year survival rate for advanced nonsquamous and squamous NSCLC without oncogenic drivers remains poor. However, several different chemo-immunotherapy combinations are presently being investigated - with favorable results- in order to increase the PFS and OS rates of these patients. Areas covered : Therefore, this paper aims to discuss the most promising trials investigating chemo-immunotherapy combinations and their present and future impact on advanced NSCLC treatment paradigms. Expert opinion : First line chemo-immunotherapy combinations are starting to and will certainly revolutionize the current paradigm of metastatic non small cell lung cancer treatment due to their superior performances - both in terms of PFS and OS - when compared to the actual standard of care platinum based chemotherapy. However, these associations are not devoid of problems, in fact, combining immunotherapy with chemotherapy obviously leads to enhanced treatment-related toxicities and to higher discontinuation rates; therefore these treatments should be administered carefully.
