What happens if colon cancer goes untreated?
Left untreated, these colon cancers grow and eventually spread through the colon wall to involve the adjacent lymph nodes and organs. Ultimately, the cancer cells spread (metastasized) to distant organs such as the liver, lungs, brain, and bones.
How fast does untreated colon cancer progress?
Colon cancer, or cancer that begins in the lower part of the digestive tract, usually forms from a collection of benign (noncancerous) cells called an adenomatous polyp. Most of these polyps will not become malignant (cancerous), but some can slowly turn into cancer over the course of about 10-15 years.
What is the survival rate for Stage 2a colon cancer?

Is colon cancer a painful death?
One of the most feared symptoms of death is pain. If your loved one is dying from colon cancer, they most likely have diffuse metastases . That means their cancer has spread from the colon to other organs and lymph nodes. Metastatic cancer often causes pain in the location where cancer has spread.

Stage II disease falls somewhere in between. An estimated 75% of people with stage II colon cancer will be cancer-free 5 years later, without adjuvant chemotherapy, but 25% will not. Some of these patients may benefit from having chemotherapy after surgery. So, how do we know which patients are most likely to benefit from chemotherapy? That is the million-dollar question, which we will take a stab at addressing here.
What to consider when treating stage 2 colon cancer?
The best we can do is look at each patient and their tumor individually.
What is the treatment for colon cancer?
In stage I colon cancer, surgery to remove the tumor is the only treatment needed. Stage III tumors, which are tumors that have spread to the lymph nodes, are treated with surgery followed by chemotherapy (called adjuvant chemotherapy; it is given after surgery to reduce the risk of a recurrence of the cancer).
Why is colon cancer so emotional?
A diagnosis of colon cancer brings about many emotions because of the uncertainty it causes; uncertainty about side effects, the ability care for ourselves, and most importantly, our life expectancy. A diagnosis of stage II colon cancer has an added concern - the question of whether chemotherapy following surgery is beneficial.
What are the high risk features of a tumor?
High Risk Features. A few “features” of a tumor have been found to put a person at higher risk of the cancer coming back.

What is colon cancer?
Colon cancer, often referred to collectively as colorectal cancer, is a progressive disease that advances in stages if left untreated. To predict the likely outcome ( prognosis ), doctors will stage the disease based on the characteristics of the tumor and the extent to which it has spread in the body.

What is the relative survival rate?
Based on data collected by the National Cancer Institute's Surveillance, Epidemiology, and End Results (SEER) program, researchers are able to estimate the percentage of people who will survive for a specific period of time following their diagnosis. This is referred to as the relative survival rate.
What are the biological characteristics of colorectal cancer?
One such characteristic is its slow growth in patients in advanced stages. For the past 15 years, no effective systemic treatment has been available in clinical practice. The present study involved a retrospective evaluation of patients with advanced colorectal cancer in order to assess the median and overall survival of patients. Concurrently, the study aimed to describe the biological characteristics of this slow-growing disease and the quality of life of the patients. The key characteristic of this patient group was the lack of any systemic treatment. The study included 40 patients (25 male and 15 female, median age 67 years) who were evaluated between 1993 and 1996. Only supportive treatment was provided. One patient underwent 2 cycles of chemotherapy. Liver surgery was unsuccessfully performed on 3 patients. Two patients underwent radiofrequency once and 2 had intra-arterial treatment, also once. The results showed the median survival of patients to be 24 months (range 16–42). One-year survival was found to be 65% while the 2-year survival was found to be 25%. A satisfactory quality of life was also observed. In conclusion, colorectal cancer is a slow-going malignancy, as indicated by the long-term survival of patients and the biological characteristics of the tumor.
What is the effect of chemotherapy on colorectal cancer?
According to the RECIST criteria, stable disease is defined as a tumor reduction of less than 30% and tumor progression of less than 20% (18). Where evaluation by CT after treatment showed stable disease, the result may be attributed to either: i) the effect of chemotherapy, which inhibited disease progression , or ii) the biological characteristics of the tumor, which define how rapidly it develops. It is difficult to verify which interpretation applies in routine clinical practice. Relevant data are required to determine whether chemotherapy plays a significant role in regulating disease progression. One example of how data may be gathered involves a comparison of treated versus non-treated patients in a randomized trial. A study by Cunningham et al, which compared chemotherapy with irinotecan plus supportive care versus supportive care alone, showed that overall survival was significantly higher in the irinotecan group (p=0.001) (18). Results by these authors showed that one-year survival for the irinotecan group was 36.2% compared with 13.8% for the supportive care group. These percentages of one-year survival for each group are lower than those obtained in our study. The reason for this discrepancy is that the previous study included the time period after the administration of second-line treatment (18). On the other hand, the results of the study by Cunningham et al(18) indicate the advantage of chemotherapy in colorectal cancer. The aim of our study was to contribute to a better understanding of the biology of colorectal cancer. Our findings indicate that this is a slow-growing disease with a 65% survival rate after 1 year, and a 25% survival rate after 2 years (10/40 patients). Local treatment administered to 11/40 patients (27.5%) contributed little to overall survival.

Can metastatic colorectal cancer be treated without treatment?
The long-term survival of patients with metastatic advanced colorectal cancer without systemic treatment may be due to the biological characteristics of this tumor, indicating that it is a slow-growing malignancy. These findings are useful in obviating long-term or unstoppable chemotherapy when patients are in stable disease.

Staging Terminology
- A tumor is staged using the "TNM" system, which incorporates the Tumor size/depth, presence of cancer in lymph Nodes, and whether or not Metastases are present. Stage II colon cancer includes tumors that are T3N0M0 or T4N0M0. 1. T3 tumors invade through the muscularis propria (outer layer of the colon) and into the peri-colorectal tissues (tissue s...
Not All Stage II Tumors Are Alike
- Though stage II tumors are grouped together, there are some that appear more likely to come back after treatment and may benefit from adjuvant chemotherapy. There are some features of the tumor that increase the chance that the cancer will come back.

- Genomic profiling, using a gene signature, is an analysis of the level of expression of a group of genes in the tumor tissue, which is then used to predict outcomes. It is important to note that the genes being looked at are the mutated genes that are a part of the tumor. They are not the genes that you inherited from your parents. Genetics is the study of genes that are inherited and passe…
