説明

<p>Chemotherapy for cancer has significantly improved owing to the increasing number of effective chemotherapeutic agents and supportive care. Recently, the number of older cancer patients has rapidly increased owing to the aging of the global population. However, in most cases, it is difficult to treat those using similar dosages or schedules as that of younger patients because older patients generally have unfavorable factors, such as decreased performance status and physical and cognitive conditions, thus increasing the incidence of complications and side effects. Chemotherapy for gastrointestinal cancers has made significant progress in recent years with the introduction of molecular-targeted agents and immunotherapy. However, clinical trials showed limited evidence regarding the efficacy of chemotherapy in older cancer patients, accounting for half of all patients, making it difficult to develop a well-established treatment strategy. This review aimed to evaluate the current state of chemotherapy for gastrointestinal cancer in older adults. Furthermore, the limitations and future perspectives were discussed. J. Med. Invest. 69 : 25-30, February, 2022</p>
