Immunotherapy in the Treatment of Cancer: Today and Tomorrow

This review aims to synthesize the latest advances in immunotherapeutic cancer treatment approaches and spotlight groundbreaking discoveries and clinical trial outcomes.

Immunotherapy represents a promising and transformative strategy for treating a variety of hematological malignancies and solid tumors. This therapeutic approach strives to bolster the body's inherent defense mechanisms to elicit enduring, specific, and individualized anti-tumor responses by harnessing the immune system's ability to identify and eradicate cancer cells. Various modes of immunotherapy—including monoclonal antibodies, immune checkpoint inhibitors, cancer vaccines, adoptive T-cell therapies, and oncolytic viruses—have achieved considerable success in clinical trials and patient results.

Despite notable successes, challenges persist in the broader adoption of immunotherapy. Issues such as resistance mechanisms, tumor heterogeneity, and the complexity of the tumor microenvironment can weaken immune responses and constrain the efficacy of treatments. The current review is dedicated to understanding these obstacles and devising comprehensive strategies to surmount resistance and secure sustained responses.
