Survival rates vary for adenocarcinoma of the colon, but these statistics will give you a general idea of the survival rate for Singapore residents who have adenocarcinoma of the colon. The five-year survival rate represents the percentage of patients alive five years after their initial diagnosis with adenocarcinoma of the colon.
 

Five-Year Survival Statistics for Women in Singapore:

  • Localized adenocarcinoma of the colon: 70%
  • Adenocarcinoma of the colon with regional metastases: 44%
  • Adenocarcinoma of the colon with distant metastases: 12%

Five-Year Survival Statistics for Men in Singapore:

  • Localized adenocarcinoma of the colon: 68%
  • Adenocarcinoma of the colon with regional metastases: 50%
  • Adenocarcinoma of the colon with distant metastases: 12%

These adenocarcinoma survival statistics were derived from a study published in the journal Diseases of the Colon and Rectum. The researchers examined data from cancer patients registered in the Singapore Registry from 1968 – 1997.

 

More Information About Colon Cancer

Colon cancer is most commonly comprised of a histological, or cellular variant, called adenocarcinoma. Adenocarcinoma forms from glandular or mucus-secreting cells in the colon.

Although a leading cause of death, in recent years, there has been a slow decline in both the incidence of and deaths caused by colon cancer in the United States.

Colon cancer usually occurs in people aged 50 years and older and peaks in people who are around 65 years old.

Colon cancer arises from polyps in the colon that become cancerous. The following risk factors contribute to this malignant transformation:

  • obesity
  • consumption of too much red or processed meat

For people with symptoms suggestive of colon cancer, this disease is usually diagnosed using colonoscopy with biopsy.

Here are some symptoms of colon cancer:

  • abdominal or rectal mass
  • weight loss
  • abdominal bloating
  • abdominal swelling (ascites)
  • blood in the stool
  • narrow-caliber stools

Here are the stages of colorectal cancer:

  • Stage 0 cancer is restricted to the surface of the colon or rectum.
  • Stage I cancer has penetrated deeper into the colon or rectum.
  • Stage IIA, IIB and IIC cancer has grown through the wall of the colon or rectum and, depending on the specific substage, may have grown into surrounding structures. However, the cancer hasn't yet made it to the lymph nodes. (Once cancer makes it to the lymph nodes, it can metastasize.)
  • Stage IIIA, IIIB and IIIC cancer has spread to the lymph nodes.
  • Stage IVA and IVB cancer has spread to one or more distant organs.

Of note, more advanced stages of colon cancer demonstrate metastases or spread of the cancer from the colon to other places in the body like the liver or lungs.

Treatment of colon cancer depends on stage and includes chemotherapy and surgery, such as resection of the colon (which unfortunately means that the patient will need a colostomy bag).

Please keep in mind that beginning at age 50, you must be screened for colon cancer. Depending on the type of screening test used, the frequency of this testing varies. For example, a screening colonoscopy is performed once every 10 years in people without evidence of cancer, and a flexible sigmoidoscopy is performed once every 5 years in people without evidence of cancer.
