Abstract
The introduction of T-cell targeted immunomodulators blocking the PD-1 and PD-L1 axis is unquestionably one of the most notable advancements in the treatment of advanced or metastatic solid malignancies, including bladder cancer. Immune checkpoint antibodies are now widely utilized as monotherapies or in combination with other systemic therapies in the first or subsequent lines of treatment in approximately 50 cancer types. Deep and durable responses and long tails of survival curves are hallmarks of patients treated with immune checkpoint inhibitors. However, treatment can have negative impacts, including serious treatment-related side effects as well as a high financial burden to individual patients and the healthcare system. There is increasing data that the benefit of immune checkpoint treatment may persist after treatment is discontinued for reasons other than progressive disease, particularly in patients who have achieved a durable complete response. However, the optimal treatment duration and activity after treatment reinitiation remains undefined and will likely be influenced by disease biology (histology and genomics), treatment (monotherapy or combination therapy), and disease context (depth and duration of response). Well-designed prospective clinical trials and the development and validation of biomarkers that predict outcomes after treatment cessation are needed to move the field forward.
期刊介绍:
Bladder Cancer is an international multidisciplinary journal to facilitate progress in understanding the epidemiology/etiology, genetics, molecular correlates, pathogenesis, pharmacology, ethics, patient advocacy and survivorship, diagnosis and treatment of tumors of the bladder and upper urinary tract. The journal publishes research reports, reviews, short communications, and letters-to-the-editor. The journal is dedicated to providing an open forum for original research in basic science, translational research and clinical medicine that expedites our fundamental understanding and improves treatment of tumors of the bladder and upper urinary tract.
