[4] Choueiri collaborated with Paul Nguyen in 2011 to perform a meta-analysis of randomized studies involving 4,141 prostate cancer patients to conclude whether men receiving ADT had a higher rate of cardiovascular deaths.

[9] In 2017, Choueiri led a study which found that patients with metastatic papillary renal cell carcinoma benefited from savolitinib, a drug targeted to an abnormal genetic pathway causing cancerous growth.

[10] The following year, Choueiri was appointed full professor of medicine at Harvard Medical School and continued in his position as the director of the Lank Center for Genitourinary Oncology.

[15] Similarly, Choueiri also collaborated with William Kaelin Jr. in translational and clinical research, including recently around HIF2 inhibitors in clear-cell renal cancer, where he reported on activity and safety of MK-6482 in highly refractory RCC patients.

[20][21] Later that year, Choueiri presented during the plenary session of the ASCO meeting the results of KEYNOTE-564 trial that showed for the first time that immunotherapy can be efficacious in the adjuvant setting in high-risk renal cancer, culminating in the FDA approval of pembrolizumab in RCC after surgery.
