Education and Scientific Exchange

SITC continues to trailblaze as the premier destination for education in the cancer immunotherapy field. From record abstract submissions at the society’s 38th Annual Meeting to the first SITC Spring Scientific, the education offered by SITC and presented by the immunotherapy community reflected incredible progress and possibility of this field.

38th Annual Meeting & Pre-Conference Programs

The SITC 38th Annual Meeting & Pre-Conference Programs (SITC 2023) continued its reign as the leading destination for scientific exchange, education, and networking in the cancer
immunotherapy field.


Registration

SITC 2023 had nearly 6,000 attendees in person and virtually.


Abstracts

SITC 2023 saw a record number of abstracts with1,640 submissions, over 65 oral abstracts, and over 1,400 poster abstract presentations.

Scientific Exchange

The Annual Meeting highlighted exciting advances and emerging areas of interest in the field, including:

  • Dynamic remodeling of lymphoid and myeloid cellular populations in the tumor microenvironment during the anti-tumor immune response
  • The potential of cancer vaccines to boost anti-cancer immunity and prevent or treat a variety of tumor types
  • The relationship between metabolism, immune cell function and fate, and anti-tumor immunity
  • Innovative technologies and next-generation immunotherapies to address current hurdles in the field and to usher in the future of immuno-oncology

Each year, the Annual Meeting features two distinct lectures comprised of one keynote and one talk given by the Richard V. Smalley Memorial Award & Lectureship recipient. In her keynote address, Stressing Out the Immune System in Cancer, Dr. Susan Kaech provided new insights to the dynamic nature of the anti-cancer response of T lymphocytes and how metabolic changes in the tumor microenvironment affect T cell differentiation and function. She provided new insights to the dynamic nature of the anti-cancer response of T lymphocytes and how metabolic changes in the tumor microenvironment affect T cell differentiation and function. Dr. Kaech’s presentation concluded with new insights on the relationship between neurotransmitters and the T cell-mediated anti-cancer response, and how these interactions can influence response to cancer immunotherapy. 

The Richard V. Smalley Memorial Award & Lectureship was presented by Robert D. Schreiber, PhD, FAIO. In his presentation, Cancer Immunoediting: Targets, Mechanisms and Implications for Immunotherapy, Dr. Schreiber presented a comprehensive analysis of past work that led to the discovery of cancer immunoediting and how these advances continue to inform the development of new immunotherapies. He also presented new, high-dimensional analyses of spatial remodeling of the tumor microenvironment during cancer immunotherapy, providing new mechanistic insights to how the immune system destroys cancer cells.


The CheckPoints Party

Comprised of SITC members and cancer immunotherapy all-stars, The CheckPoints band performance has been a highlight of the SITC Annual Meeting experience for the past ten years. Cited as “the World’s Brainest Cover Band” by The Wall Street Journal in June 2023, the band was "Surfing for a Cure" while performing at the San Diego Marriott Marquis hotel.


Exhibit Hall

SITC 2023 included a record number of exhibitors! Participants saw a plethora of products and services that advance research and accelerate laboratory results. The Exhibit Hall's new Refresh and Recharge station allowed conference attendees to take a break and charge their devices while perusing SITC's many esteemed award recipients.


SITC Fun Run

Thank you to everyone who joined us for our first SITC Fun Run! Our motivated group of early risers enjoyed an exhilarating 5k jog along the San Diego Embarcadero Marina Park, with beautiful views of the marina - including the USS Midway Museum!


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

The SITC Spring Scientific, Host Immunity in Immunotherapy Responses: From Discoveries to Precision Oncology, took a holistic approach to addressing factors affecting the host and response to immunotherapy beyond the tumor microenvironment.


This niche program featured in-depth discussions of scientific breakthroughs, cutting-edge methodologies and technologies, and the newest clinical studies on environmental, genetic, and patient-specific factors affecting patient health and response to immunotherapy.

Targets for Cancer Immunotherapy: A Deep Dive and SITC-NCI Computational Immuno-oncology Webinars

SITC aligned its two premier scientific webinar series and explored the latest advances in gene and cell therapy drug development alongside the computational considerations in the evolution of these novel therapies.


SITC hosted this third online seminar series of its kind, exploring the underlying biology of various immunotherapy drugs. Through this deeper understanding, participants may address important scientific questions and rationally design cancer immunotherapy clinical trials.


Nearly 300 attendees

Six webinars including topics on:

  • Immune Deserts Multiple
  • Gene Modification
  • and T Cells CAR-T Engineering in Solid Tumors
