Scientific Exchange

The Annual Meeting showcased major scientific advances and emerging areas shaping the future of immuno-oncology, including the use of radiomics and other computational approaches to inform diagnosis, personalize immunotherapy, and monitor patients with cancer; the role of neuroimmune communication in tumor biology and immunotherapy response or resistance; the mechanisms and clinical applications of B-cell–directed therapies across cancer and autoimmune disease; and the development of innovative technologies, next-generation immunotherapies, and immune modulators designed to address current challenges and advance the field.

Each year, the Annual Meeting features two distinguished lectures: a keynote and a presentation by the recipient of the Richard V. Smalley Memorial Award & Lectureship. In her keynote, Targeting the Microbiome to Promote Health and End Cancer, Jennifer A. Wargo, MD, MMSc of The University of Texas MD Anderson Cancer Center, delivered a comprehensive overview of the tumor and human microbiomes and their influence on cancer development, immunotherapy response, and overall health. She concluded by highlighting emerging opportunities to translate these insights into improved patient outcomes.

Ira Mellman, PhD, FAACR, FAIO of the Parker Institute for Cancer Immunotherapy and Medici Therapeutics, was the 2025 recipient of the Richard V. Smalley, MD, Memorial Award and Lectureship. In his presentation, “The Coming Renaissance of Cancer Immunotherapy,” Dr. Mellman reviewed key scientific and clinical achievements in immuno-oncology over the last 15 years, while outlining remaining unanswered questions, emerging strategies to address them, and promising new directions for the field.


The CheckPoints Party

Celebrating four decades of progress in cancer immunotherapy, SITC’s 40th Anniversary Party featuring The CheckPoints brought the SITC family together for an unforgettable evening of music and community. Beyond showcasing band’s repertoire, the event served a meaningful purpose: raising critical support for early career scientists through SITC’s Forward Fund.

The celebration also featured a special auction of Neil Canavan’s personal collection of hand-drawn sketches from leaders in the field, each offering a unique and personal perspective on how these visionaries conceptualize their research. Together, these efforts successfully met the $100,000 fundraising goal for SITC’s Forward Fund, representing a significant investment in fellowships, special awards, and other opportunities that advance research, education and development of the next generation of cancer immunotherapy scientists.

A special thank you to our sponsors: 7 Hills Pharma, LLC, Akoya Biosciences, BostonGene, Immatics, Immunocore, and Moffitt Cancer Center.


Exhibit Hall

The SITC 2025 exhibit hall featured 140 exhibitors spanning pharmaceutical and biotechnology companies, non-profit organizations, academic institutions, and other groups delivering essential resources and services to advance cancer research and patient care.


SITC Fun Run

SITC hosted its third Annual Meeting fun run/walk on the morning of Friday, Nov. 7 in National Harbor, MD. Approximately 40 attendees participated in the informal event, which took place along the Potomac River and offered a relaxed opportunity for connection and wellness during the Annual Meeting.


Early Career Scientist Events

The future of cancer immunotherapy is rooted in research and education, primarily by early career scientists. SITC’s Early Career Scientist (ECS) Committee oversees the activities at SITC’s Annual Meeting & Pre-Conference Programs for those in the early stages of their careers.

Spring Scientific: Cellular Therapy for Solid Tumors


The SITC Spring Scientific: Cellular Therapy for Solid Tumors highlighted recent advances in adoptive cellular therapies and examined the rate-limiting challenges that continue to hinder the translation of these approaches to patients with solid tumors. Through in-depth presentations and discussions, the program explored emerging scientific insights, unresolved questions, and new opportunities related to target antigen selection, product design, and therapeutic efficacy and safety.

The 2025 Spring Scientific achieved record-breaking engagement. Faculty presentations reflected a high caliber of scientific excellence, and participants valued the depth of the scientific content and the robust networking opportunities the program provided.

This program is supported, in part, by grants from Agilent Technologies, AstraZeneca, Iovance Biotherapeutics, Kite Pharma, Inc., Merck Sharp & Dhome LLC, Obsidian Therapeutics, and Sanofi.

Advances in Cancer Immunotherapy™


The 2025 Advances in Cancer Immunotherapy™ (ACI) series continued to provide clinicians with practical, cutting-edge education on immuno-oncology (IO) treatments and patient care considerations. Through a combination of tumor board–style panel discussions and in-depth clinical updates on newly approved therapies, this flagship program evolved to meet the needs of today’s multidisciplinary care teams. In 2025, SITC delivered nine live virtual ACI programs and expanded its in-person reach with three sessions held in conjunction with the annual meetings of the Society of Interventional Oncology (SIO), the Advanced Practitioner Society for Hematology and Oncology (APSHO), and the American College of Rheumatology (ACR).


Over 1,000 attendees

Targeted programming covering specific disease states and therapeutic modalities
12 programs, now available on-demand


The 2025 Advances in Cancer Immunotherapy™ series is supported, in part, through independent medical education grants from AstraZeneca, GSK, Merck Sharp & Dohme LLC, a subsidiary of Merck & Co. Inc., and Replimune Inc.

Collaborative Education Programs (CEPs)


SITC has a long-standing track record of impactful collaborations with leading scientific and clinical organizations. These partnerships align closely with SITC’s strategic priorities by advancing its mission and delivering high-quality, effective educational and scientific programming. In 2025, SITC participated in a broad range of collaborative initiatives:

Translational Research Cancer Centers Consortium (TRCCC) 2025 Annual Meeting

February 19-21, 2025 | Champion, PA

SITC co-organized a session convening leaders in cell and gene therapy to explore cell therapies for solid tumors. SITC supported participation through travel awards for two faculty awardees and four postdoctoral investigator awardees and enhanced SITC’s visibility through onsite exhibiting.

SITC Joint Session and Travel Awards at the TRCCC Annual Meeting

SITC collaborated with the Translational Research Cancer Centers Consortium (TRCCC) on a joint a pre-meeting session at titled Cell Therapy for Solid Tumor. The session, chaired by Daniel Powell, PhD, discussed key challenges and advances in tumor-infiltrating lymphocytes (TILs), TCR gene therapy, CAR T cells, and emerging unconventional approaches for solid tumors. Over 200 individuals registered for the workshop, exceeding expectations and prompting a registration cap to stay within capacity.

As part of the 2025 SITC-TRCCC collaboration, SITC supported travel awards for two faculty speakers and four postdoctoral investigators.

In addition to the joint session, Journal for ImmunoTherapy of Cancer (JITC) Editor-in-Chief Michael T. Lotze, MD, led a “Meet the Editor” forum, where he discussed academic publishing, careers in scientific journals, and what editors look for in JITC submissions.

SITC maintained strong visibility throughout the meeting, which welcomed 435 total attendees. An exhibiting table positioned near registration allowed a staff member to share information about upcoming programs and promote SITC membership, resulting in a number of new trainee members joining SITC.
