Allison Betof Warner, MD, PhD, on TIL Therapy for Advanced Melanoma: Innovative Clinical Advances in Treatment
Thematic Newsreels
Allison Betof Warner, MD, PhD, reviews important clinical research in the treatment of advanced melanoma, including tumor-infiltrating lymphocyte (TIL) therapy, the role of this innovative treatment in advanced melanoma, and relevant data, peer-reviewed literature, and FDA approvals in 2024. She also provides a look ahead at what is on the horizon in 2025 with regard to care for patients with advanced melanoma.
Jennifer Gile, MD, of Willamette Valley Cancer Institute, talks about the first positive phase III trials in the high-risk diffuse large B-cell lymphoma (DLBCL) space—POLARIX and frontMIND. POLARIX established the superiority of a modified regimen of rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) called pola-R-CHP, in which vincristine was replaced with polatuzumab vedotin, over standard R-CHOP; frontMIND showed that the addition of the CD19 monoclonal antibody tafasitamab plus the immunomodulatory drug lenalidomide to R-CHOP also improved outcomes over standard R-CHOP. Dr. Gile discusses current considerations when choosing between these regimens and how future research may lead to even more refined patient selection.
Jennifer Gile, MD, of Willamette Valley Cancer Institute, reviews findings from the POLARIX study, a double-blind, placebo-controlled, international phase III trial that evaluated pola-R-CHP—a modified regimen of rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP), in which vincristine was replaced with polatuzumab vedotin—as compared with standard R-CHOP, in patients with previously untreated intermediate-risk or high-risk diffuse large B-cell lymphoma (DLBCL). With a 5-year update from the trial being published recently, Dr. Gile discusses long-term results, the regimen’s performance in key high-risk subgroups, and how the study altered the front-line management of this disease.

Circulating tumor DNA has many roles in cancer treatment: early diagnosis, tumor profiling, determining response to therapy, and tracking clinical dynamics. In this video, Arvind N. Dasari, MD, MS, of The University of Texas MD Anderson Cancer Center, focuses on it as a marker for measurable residual disease (MRD), which can help to determine risk of disease recurrence in patients with cancer. Dr. Dasari reviews the development of assays for MRD, both tumor-informed and tumor-agnostic, and provides top-level data from several clinical trials on the topic that have informed the role of MRD testing in both the colorectal cancer and general solid tumor space.

Kent Shih, MD, of Tennessee Oncology, shares three patient cases that illustrate how gene-expression profiling (GEP) in patients with melanoma helps shape the decision to proceed to sentinel lymph node biopsy (SLNB) and how often and thorough follow-up should be with medical oncology.

Raajit K. Rampal, MD, PhD, Director of the Center for Hematologic Malignancies and the Myeloproliferative Neoplasms Program at Memorial Sloan Kettering Cancer Center, reviews the four FDA-approved Janus kinase (JAK) inhibitors for patients with myelofibrosis, touching upon differences in their mechanisms of action and toxicity profiles. He also discusses clinical trials of add-on drugs to the currently approved JAK inhibitors, which may increase their efficacy and durability, as well as trials of novel JAK inhibitors and immunotherapies targeting CALR.
