Our rectal cancer clinical calculators are designed to help patients and their physicians calculate the likely outcomes of their treatment for rectal cancer with multimodal therapy (a combination of chemotherapy, radiotherapy, and surgery) or total neoadjuvant therapy (chemotherapy and radiotherapy) followed by either watchful waiting or surgery. These tools are appropriate for patients with rectal cancer that has not spread beyond the rectum or regional lymph nodes.
All results from these tools should be discussed with a physician and understood in the context of each patient’s program of care. Results produced by these tools are based on data from patients treated at large research institutions with physicians who perform a high volume of rectal cancer procedures.
Disease-Free Probability and Overall Survival After Treatment for Rectal Cancer
This clinical calculator is a tool designed to predict the likelihood of surviving free of rectal cancer five years after undergoing multimodal therapy (treatment that combines chemotherapy, radiotherapy, and surgery) to remove cancerous tissue. This tool also predicts the likelihood of surviving at least five years after undergoing multimodal therapy for rectal cancer. It is appropriate for patients whose rectal cancer has shown no evidence of distant metastasis or spread to other organs beyond the rectum or regional lymph nodes before multimodal therapy or at the time of multimodal therapy.
Disease-Free Probability at Any Time After Total Neoadjuvant Therapy (Chemotherapy and Radiation) for Rectal Cancer Treated with Surgery or Watch-and-Wait
This clinical calculator is a tool designed to predict the likelihood of surviving free of rectal cancer five years after undergoing total neoadjuvant therapy (treatment that combines chemotherapy and radiotherapy) with watch and wait, immediate or delayed surgery. The tool is appropriate for patients whose rectal cancer has shown no evidence of distant metastasis or spread to other organs beyond the rectum or regional lymph nodes before total neoadjuvant therapy or at the time of total neoadjuvant therapy.
