Removing cancer by surgery is a common first step for patients with colon cancer, and a possible second step after chemotherapy for patients with rectal cancer.
A leader in colon cancer surgery
We are named a High Performing Hospital for Colon Cancer Surgery by U.S. News & World Report, a designation that reflects our exceptional ranking for survival rates, number of procedures performed, nurse-to-patient ratio, and proportion of patients able to return home and post-surgery and resume normal activities
Our surgeons perform the majority of colon and rectal surgeries with minimally invasive techniques such as laparoscopic or robotic procedures. These approaches offer patients several benefits over traditional, open surgery, including:
- Smaller incisions that heal faster with less scarring
- Less pain
- Shorter hospital stay
- Faster recovery
To treat your cancer, our colorectal surgeons may recommend one of the following procedures:
- Colectomy to remove the portion of the colon containing the cancer and reconnect the healthy portions back together. How much of the colon is removed depends on your blood supply, the drainage patterns of your lymph nodes, the tumor’s location and the extent of your disease.
- Colostomy. This procedure (performed at the same time as a colectomy) creates a new path for waste to leave the body through the abdominal wall into a colostomy bag, a plastic pouch worn outside the body. This allows the colon and rectum time to heal after surgery to remove the cancer. For most of our patients, the colostomy is temporary and can be reversed with another small surgical procedure.
- Transanal endoscopic microsurgery (TEM) is a minimally invasive surgical procedure performed through the anus for early-stage rectal tumors or in patients who have several other health conditions that make other surgery types too risky for them.
- Endoscopic mucosal resection (EMR) is a minimally-invasive procedure performed through an endoscope to remove early tumors of the colon or rectum.
- Lymph node surgery to remove the lymph nodes associated with the portion of the colon or rectum that is removed is an important part of treatment and staging. These lymph nodes must be analyzed properly to determine whether they contain any cancerous cells. Cancer that has spread to lymph nodes means you’ll likely need other treatment beyond surgery, such as chemotherapy.
- Total Mesorectal Excision (TME) is a critical procedure for patients with rectal cancer. This surgery removes the rectum along with the surrounding lymphatic tissue, called the mesorectum. Ensuring complete removal by a skilled surgeon is essential to reduce risk for recurrent cancer.
The Roswell Park advantage
In cancer surgery, the ability to remove the cancer entirely and achieve a clear (or negative) margin — where the tissue surrounding the tumor is cancer-free — is paramount to curing the cancer. Roswell Park has unique capabilities to ensure clear margins or treat any high risk (or positive) margins, such as:
- Mid-procedure pathology review allows tissue samples from the margin area to be analyzed by a pathologist on the spot, confirming cancer-free margins before the surgery is completed.
- Intraoperative radiotherapy delivers radiation to the margin area during the operation to kill any residual, microscopic cancer cells.
