Colorectal Cancer Treatment in India
The Colorectal Cancer Treatment, also called the colon cancer treatment, depends on the diagnosis results and the types and stage of the cancer. The diagnosis procedures of rectal cancer are digital rectal exam (DRE), fecal occult blood testing, colonoscopy, CT scans, MRIs, and endoscopic ultrasound (EUS) and sigmoidoscopy. After the confirmation of the rectal cancer in diagnosis, the clinical stage is started by the doctors. Patients in the stage of ii and iii are treated with radiotherapy and chemotherapy.
Surgery is the most common treatment for colorectal cancer. During surgery, the tumor, a small margin of the surrounding healthy bowel, and adjacent lymph nodes are removed. The surgeon then reconnects the healthy sections of the bowel. In patients with rectal cancer, the rectum is permanently removed. The surgeon then creates an opening (colostomy) on the abdomen wall through which solid waste in the colon is excreted.
Chemotherapy is the use of medications to kill cancer cells. It is a systemic therapy, meaning that the medication travels throughout the body to destroy cancer cells. After colon cancer surgery, some patients may harbor microscopic metastasis (small foci of cancer cells that cannot be detected). Chemotherapy is given shortly after surgery to destroy these microscopic cells. Chemotherapy given in this manner is called adjuvant chemotherapy.
Radiation therapy in colorectal cancer has been limited to treating cancer of the rectum. There is a decreased local recurrence of rectal cancer in patients receiving radiation either prior to or after surgery.
Other treatments have included the use of localized infusion of chemotherapeutic agents into the liver, the most common site of metastasis. This involves the insertion of a pump into the blood supply of the liver which can deliver high doses of medicine directly to the liver tumor.
Still other experimental agents include the use of photodynamic therapy. In this treatment, a light sensitive agent is taken up by the tumor which can then be activated to cause tumor destruction.
A new kind of treatment is in place and it is called the monoclonal antibodies. These molecules block a receptor for a growth factor, situated on the cancerous cells. Other can act on the tumor vascular development by blocking the receptor for the vascular growth factor. This is a development with the molecular oncology department taking its research to new dimensions for curing cancer.
Technology used for Treating Colorectal Cancer
Apart from surgery and chemotherapy, the new age technology used to treat cancer include Radiology and Radiation Oncology, which are advanced imaging technology that can be used to detect cancer.
Technologies for detection of cancer:
- Computerized Tomography (CT)
- Nuclear Medicine
- PET Fusion
- Robotic Surgical System
- Trilogy Image Guided Radiation Therapy System (IGRT)
- Intensity Modulated Radiation Therapy System (IMRT)
