Cancer treatment is presently one of the most important challenges in medical science. Surgery, chemotherapy, radiotherapy, or combining these methods is used to eliminate the tumor. Hormone therapy, bone marrow transplantation, stem cell therapy as well as immunotherapy are other well-known therapeutic modalities. Immunotherapy, as the most important complementary method, uses the immune system for treating cancer followed by surgery, chemotherapy, and radiotherapy. This method is systematically used to prevent malignancies development mainly via potentiating antitumor immune cells activation and conversely compromising their exhaustion with the lowest negative effects on healthy cells. Active immunotherapy can be employed for cancer immunotherapy by directly using the ingredients of the immune system and activating immune responses. On the other hand, inactive immunotherapy is utilized by indirect induction and using immune cell-based products consisting of monoclonal antibodies. It has strongly been proved that combination therapy with immunotherapies and other therapeutic means, such as anti-angiogenic agents, could be a rational plan to treat cancer. Herein, we have focused on recent findings concerning the therapeutic merits of cancer therapy using immune checkpoint inhibitors (ICIs), adoptive cell transfer (ACT) and cancer vaccine alone or in combination with other approaches. Also, we offer a glimpse into the current challenges in this context., Competing Interests: Competing interests There is no conflict of interests., (Copyright © 2022. Published by Elsevier GmbH.)

Lung cancer is one of the leading causes of tumor-related mortalities worldwide. NSCLC is the most common type of lung cancer. In recent years, advancements in chemoradiotherapy and immunotherapy have led to unprecedented survival benefits in some patients. However, conventional therapies such as radiation and chemotherapy are not effective in all patients due to the chemo or radioresistance mechanisms; as a result, there is an urgent need for understanding the resistant mechanism. Given that malignancies are caused by changes in cell homeostasis, autophagy may help chemo/radiosensitization by removing damaged compartments and enhancing tumor clearance. Autophagy, on the other hand, may help cancer cells survive by increasing the breakdown of cell cycle regulators. Considering these inconsistencies, this study aimed to overview the intricacy of autophagy in response to chemoradiotherapy in lung cancer., (Copyright © 2022. Published by Elsevier GmbH.)
