What would b classed as terminal colon cancer , ie how many tumors (mets) in the body, how big etc ?

Organ failure: Number and size of lesions does not determine terminal disease. Many colon lesions recurr in mid abdomen as extensive lesions producing bowel obstruction.

Why are tumor deposits in colon cancer considered as lymph nodes when there are no lymphovascular invasion, because of td it's becoming a stage 3?

Why are tumor deposits in colon cancer considered as lymph nodes when there are no lymphovascular invasion, because of td it's becoming a stage 3?

Local spread: If the tumor deposits are located away from the main primary, then most authorities consider them to be equivalent to a positive lymph node(s). Most likely these deposits got there via lymphovascular invasion even if the pathologist could not see that histologically on the slides. The ajcc also considers discontinous tumor deposits as n1c in the pathological staging system. ...Read more

I had stage iii-b colon cancer and the tumor was removed surgically. I went to 2 oncologists who suggested different chemos: folfox vs. Capeox. I know that folfox is the standard. Does this mean it's better?

Equivalent choices: Capox is really an equivalent regimen to folfox. The difference is that the folfox regimen uses a drug (5- fluorouracil) that is given intravenously via a pump, wile the other regimen utilizes Capecitabine which is an oral version of the same drug which is activated preferentially in the tumor cells. There is a slight difference in the schedule, but these are really considered interchangeable. ...Read more

Could colon cancer T4 , no positive nodes, but isolated tumor deposits found in pericolic tissue be cured with chemotherapy and radiation?

Could colon cancer T4 , no positive nodes, but  isolated tumor deposits found in pericolic tissue be cured with chemotherapy and radiation?

Surgery is the best : Shot. A T4 lesion means the cancer has grown outside the walls of the colon and into adjacent structures. If all of the cancer can be surgically removed you can be cured. Often we add chemotherapy and radiation if there are positive microscopic cells left behind. Newer techniques such as hipec are also used in these cases. ...Read more

My husband has colon cancer, his tumor and section of colon were removed yesterday. He has an elevated white blood cell count but no fever. Problem?

My husband has colon cancer, his tumor and section of colon were removed yesterday. He has an elevated white blood cell count but no fever. Problem?

See below: All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. Having said that, the elevated white cell count is likely a normal reaction to the trauma of surgery. If he has fever, discharge from the surgical site, pain at the surgical site, then you should consult your doctor promptly. ...Read more
