Cancer is considered to be the most lethal threat to human life globally. Although, versatile strategies have been established in the field of surgery, chemotherapy, radiotherapy and im-munotherapy against cancer, discovery of new therapeutic drugs from natural products still un-derlays anticancer remedy due to their unique functional mechanisms and potential low side ef-fects. Terpenoids are among the most diversified and enormous natural products which have been proved promising in cancer treatment. Some terpenoids have been through multiple stages of clinical trials and some even approved as anticancer agent, but most of these studies empha-sized the direct effects on tumor cells while paying less attention to their systemic effects on tu-mor microenvironment (TME) Therefore, we recruited the patent drugs and investigated drug candidates of terpenoids in this review and summarized their general anti-tumor mechanisms among which the regulation on TME was highlighted. Finally, the prospect on the drug ability of terpenoids and their potential benefits in immunotherapy were discussed to illuminate fur-ther researches on these natural products. Keywords
