Dr. Deb Schrag discusses the PROSPECT Trial as part of this DocTalk

Описание: In this Doc Talk hosted by Colontown and brought to you by Dr. Manju George, Scientific Director at Paltown, Dr. Deborah Schrag, Chair of Medicine at Memorial Sloan Kettering Cancer Center, presents the findings of the PROSPECT trial, a pivotal study investigating whether select patients with rectal cancer can safely skip pelvic radiation and still achieve the same outcomes using FOLFOX chemotherapy alone. With over a decade of research and more than 1,100 patients enrolled, the trial provides critical insight into organ preservation, toxicity, quality of life, and evolving treatment standards in rectal cancer.

What you'll learn:
The origin of the PROSPECT trial and why changing standard treatment was considered risky but necessary
Which patients were eligible (T2N+, T3N0, and T3N+ rectal cancers without very distal or bulky tumors)
How the trial was designed to compare FOLFOX-first treatment to standard pelvic chemoradiation
Key results showing non-inferiority of chemotherapy alone in disease-free and overall survival
The low rates of local recurrence and identical survival outcomes in both arms at 5 years
How the intervention group had fewer temporary ostomies and more opportunities for sphincter preservation
Detailed analysis of side effects, toxicity timing, and long-term symptom resolution
The impact of treatment type on bowel function, neuropathy, fatigue, and validated sexual function scores
Why patient-reported outcomes (PRO-CTCAE) offer better insight than physician-only toxicity scoring
Limitations of the trial and next steps, including studies on more distal tumors and non-operative management
