A quantitative multigene RT-PCR assay for prediction of recurrence in stage II colon cancer: Selection of the genes in four large studies and results of the independent, prospectively designed QUASAR validation study (abstract 4000). Surgical removal of the tumor and lymph nodes is usually the only treatment needed. T4 tumors extend through the colon wall and attach to or invade a nearby structure or organs. McCleary, N.

The cancer may be in the lymph nodes. Lymph nodes are small organs that are part of the immune system and act like filters. Stage 4 . Many stage II colon cancers have grown through the wall of the colon, and maybe into nearby tissue, but they have not spread to the lymph nodes. A relative survival rate compares people with the same type and stage of colon or rectal cancer to people in the overall population. A T4 tumor – this size tumor has broken through the colon wall and into nearby tissues. This is termed as “Carcinoma in situ”. View 1 more answer. Stage II colorectal cancer. At an early stage, these abnormal outgrowths are restricted to one place, and no further spread has observed in the surroundings. Studies have found only small improvements in survival (estimated to be between 2 and 5%) with the addition of chemotherapy in stage II disease. Grade 3 tumors – these appear very abnormal under the microscope. This helps lower the chance that the cancer will come back. In Stage 2, the cancer has spread through the colon wall and possibly into the tissue around it, but it hasn’t gone into the lymph nodes. They are not the genes that you inherited from your parents. It is important to note that the genes being looked at are the mutated genes that are a part of the tumor. Stage I colorectal cancer. Oncotype DX Colon Cancer Assay – This test looks at 12 genes to predict the risk of recurrence. Individualized prediction of colon cancer recurrence using a nomogram. BRAF is described as wild-type or mutant. In stage 2 colon cancer, the disease is a little more advanced than stage 1 and has grown beyond the mucosa and the submucosa of the colon. J Clin Oncology, 27(suppl 15s). But usually, Stage 2 colon cancer takes anywhere from three to nine months to treat.

The stages of colon cancer range from stage 0 to stage 4. Stage II disease falls somewhere in between. Colorectal cancer is staged by looking at how far the tumor extends into and through the wall of the bowel T1,2,3, or 4), whether it is found in lymph nodes (N0, 1 or 2), and whether it has spread to distant organs or metastasized (M0 or M1). About staging and grading bowel cancer. But usually, Stage 2 colon cancer takes … J Natl Compr Canc Netw, 5(9), 927-936. Stage II (stage 2 colorectal cancer): Stage II colorectal cancer is divided into three categories: Stage IIA: The cancer has grown into the serosa (the outermost layer of the colon or rectum), but has not grown through it.
