In this month's 10-year anniversary issue of Targeted Therapies in Oncology™ (TTO), we feature an article on the evolution of immunotherapy approaches in oncology over the past decade. It is amazing to think about how much immunotherapy has changed the practice of oncology.
I have a somewhat fuzzy memory of a lecture I attended more than 20 years ago as a first-year oncology fellow at Memorial Sloan Kettering Cancer Center in New York, New York. If I am not mistaken, I think the lecturer was the emerging star Jedd D. Wolchok, MD, PhD, and the topic was melanoma. Dr Wolchok showed old photographs of patients whose melanoma had spontaneously regressed. Simultaneously with the regression of their melanomas, some of these patients developed vitiligo, suggesting that, in these rare and lucky individuals, their immune systems had figured out a way to attack melanocytes. These observations had convinced many scientists that finding ways to direct the immune system to attack cancer cells could help overcome the limitations of conventional chemotherapy, which seemed to have reached its potential as a therapeutic modality for cancer. I remember in the early 2000s being somewhat pessimistic about the potential of such efforts, given that attempts to harness the immune system to treat cancer had been largely unsuccessful and chemotherapy and targeted therapies were the mainstays of cancer treatment.
How wrong I was.
Fast forward 20 years and we now have seen tumor-directed monoclonal antibodies, antibody-drug conjugates, cancer vaccines, checkpoint inhibitors, oncolytic viruses, and chimeric antigen receptor (CAR)–modified cellular therapies change how we treat both solid tumors and hematologic malignancies. And of course, the field of immunotherapy for cancer is showing no signs of slowing down. Bispecific antibodies to redirect T cells toward malignant target cells are demonstrating potent activity in hematological malignancies and will likely be in the clinic soon. Inhibition of novel targets such as LAG3 and TIGIT is emerging as a way of making immunotherapy work better. Natural killer cells are undergoing evaluation as cellular therapy. Allogeneic CARs are being explored for their potential to deliver therapeutic cells.
For me, the take-home message of the cancer immunotherapy story is that basic and clinical investigators working together have created novel effective treatments that have moved the field of oncology way beyond what I was able to foresee as an oncology fellow 20 years ago. The dramatic progress in our field has been the result of collaborative efforts, with countless individuals each playing a small role to push the field forward, leading to better outcomes for patients with cancer.
Overcoming Barriers in Cancer Clinical Trials: A Path Forward for Better Patient Care
April 29th 2024Clinical trials play a pivotal role in developing effective therapies, yet their integration is challenged by issues such as insufficient reimbursement structures, misaligned incentives, physician burnout, and a complex regulatory environment.

Gholam Analyzes Treatment Outcomes for Advanced HCC in Child-Pugh B Population
April 28th 2024During a live Community Case Forum event in partnership with the Tennessee Oncology Practice Society, Pierre Gholam, MD, examined the current state of treatment for patients with hepatocellular carcinoma, looking in particular at what data is available for those with Child-Pugh B and C status who have poorer outcomes and have limited data from prospective clinical trials.
