Researcher working under a hood in a lab

Insights on Pancreatic Cancer Microbiome, Phase 2 Esophageal Cancer Study Top Roswell Park’s AACR Presentations

Multiple teams report insights and research on opportunities to improve cancer treatment outcomes

  • Annual meeting of the American Association for Cancer Research begins Friday
  • Dr. Prasenjit Dey to speak on role of helper immune cells in pancreatic cancer
  • Poster sessions highlight work across multiple types of cancer

BUFFALO, N.Y. — Roswell Park Comprehensive Cancer Center physician-scientists and researchers will present new research on emerging treatment options and population health at the 2023 annual meeting of the American Association for Cancer Research, taking place in Orlando, Florida, from April 14-19.


Prasenjit Dey, PhD, Associate Professor of Oncology in the Department of Immunology, is an invited speaker for the major symposium “Cancer Ecosystem and the Microenvironment,” happening Wednesday, April 19. Dr. Dey will discuss major findings from his lab on type 2 or “helper” immune cells and how they interact with the ecosystem surrounding pancreatic cancers with the KRAS G12D mutation, one of the most prevalent genetic abnormalities in the disease.

“We found that this mutation increases expression of the Interleukin 33 protein, or IL33, in cancer cells. When IL33 is released, it recruits and activates these type 2 immune cells, which can stimulate tumor growth,” says Dr. Dey. “Genetic deletion of the protein or antimicrobial treatment can decrease type 2 immune cells from infiltrating pancreatic cancers with this mutation.”

“In my talk, I’ll highlight the implications of these discoveries and other exciting research in the field. This latest evidence strongly suggests that antifungal and anti-IL33 therapy can be combined with immune checkpoint inhibitor immunotherapy for more effective treatment approaches and outcomes,” says Dr. Dey.

Featured Posters

Three groups of Roswell Park researchers will present posters on important topics in breast and esophageal cancer as well as cannabis use:

Arya Mariam Roy, MBBS, a hematology/oncology fellow, looked at National Cancer Institute Surveillance, Epidemiology, and End Results (SEER) Program data over an eight-year period for patients with certain subtypes of breast cancer patients and their outcomes using chemotherapy. Her presentation is Benefit of chemotherapy in early-stage breast cancer with variant histology (Abstract 919/2)

Sarbajit Mukherjee, MD, Assistant Professor in Oncology, will present preliminary results on a phase 2 study looking at Trifluridine/tipiracil (FTD/TPI) and oxaliplatin as induction chemotherapy (IC) in resectable esophageal and gastroesophageal junction adenocarcinoma (EGAC) (Abstract CT146/8)

Predoctoral trainee Michelle Goulette, alongside members of Roswell Park’s Department of Health Behavior, examine cannabis use in Roswell Park patients and survivors in Self-reported knowledge of Δ9-tetrahydrocannabinol (THC) and cannabidiol (CBD) potency in cannabis products among cancer patients and survivors: Results from a survey of cannabis consumers at an NCI-designated cancer center (Abstract 6472/26)

Additional Poster Abstracts

Several additional teams from Roswell Park have been invited to present their research findings at AACR 2023:
