The Role of Combination Chemo-immunotherapy in Advanced Non-small Cell Lung Cancer

: 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. : 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. : 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.
