Colon Cancer is the type of cancer that originates in the larger intestine called Colon. It is the final and the last section of your digestive tract. Older population and adults are mainly affected by Colon Cancer, but it can occur at any age of your life. It onsets as tiny non-cancerous clumps of cells medically termed as polyps, and it starts forming in the inner walls of the colon. Overtime it converts into Colon Cancer.
As Colon Cancer develops, different treatment options are used to control it. It includes radiotherapy, surgery and drug treatments like targeted therapy, chemotherapy and immunotherapy. The treatment option for Colon Cancer depends mainly on the extent or stage of cancer. Still, other factors are taken into consideration while deciding the best Colon Cancer treatments and medicines.

Patients with 0-Stage Colon Cancer usually have no spread of cancer to distant sites, and hence surgery is performed as the main treatment. Along with surgery, Chemotherapy is conducted post-surgery for six months, which is referred to as adjuvant treatment. Here is the guide on Colon Cancer treatment options according to the stages and extent.
Stage 0 Colon Cancer Treatment Options
In Stage-0 Colon Cancer, the polyps don’t grow beyond the inner walls of the colon, and hence surgery is the main and prime treatment option to remove the cancerous cells. The surgery is performed to remove the polyp and the masses where the cancer was formed using a local excision method called colonoscopy. If the patient has a huge tumour and can’t be removed via local excision, surgery is performed to remove a part of the colon.
Stage-1 Colon Cancer Treatment Options
In Stage-1 Colon Cancer, the polyps tend to grow deeper into the colon’s inner linings, but it has not spread outside the colon lining or in the nearby lymph nodes. Surgery is performed to remove the polyp completely, and it is called colonoscopy. If the surgery is successful and the polyp is removed without cancer cells at its edges, no further treatment is needed.
If the surgeon sees any cancer cells at the edges of the removed polyps or cancer in polyp is high grade, they may perform further surgeries. A partial colectomy is performed for cancers, not in the polyp. It is the surgical procedure to remove the section of colon that has cancer.
Stage-2 Colon Cancer Treatment Options
In Stage-2 Colon Cancer, the cancerous cells grow through the inner linings of the colon and spread into the nearby tissues, but not in the lymph nodes. Surgery is performed to remove the cancerous section of the colon, along with the nearby tissues and lymph nodes.
Some of the cases may also require adjuvant chemotherapy, especially if the cancer is at higher risk of occurring again because of different factors.
- cancer seems to be abnormal when seen under a microscope
- cancer has grown to nearby lymph nodes or blood
- If the surgeon lacks in removing at least 12 lymph nodes
- Cancer cells are blocking the colon
- Cancer found in or close to edge of removed tissues
- Cancer-causing a hole in walls of the colon
Most of the surgeons usually don’t prescribe adjuvant therapy for Stage-2 Colon Cancer patients. So, it is best to discuss with doctors about its pros and cons.
Stage-3 Colon Cancer Treatment Options
Stage-3 Colon Cancer is dangerous as it tends to spread to your nearby lymph nodes, but not to any other parts of the body. Surgery is the only treatment option where a section of the colon with cancer is removed along with nearby lymph nodes. After surgery, adjuvant chemotherapy is performed as the standard treatment in Stage-3.
Different medicines are used for the adjuvant chemo based on the health needs and age of the patients. Radiation therapy is also the option for people that are not healthy and ready for the surgical procedure for Stage-3 cancer.
Stage-4 Colon Cancer Treatment Options
Stage-4 Colon Cancer is the last stage where the cancerous cells spread from the colon to other distant tissues and organs in your body. It primarily spread to the liver and gradually spread to other organs like the brain, lungs, and distant lymph nodes and in the linings of the abdominal cavity.
Surgery is not very effective in most of the cases of Stage-4 Colon Cancer. But if the cancerous cells have spread only in limited areas in the lungs and liver, surgery is performed to remove the Colon Cancer, which may help you live longer. Multiple surgeries are performed where the section of colon comprising cancer cells are removed along with nearby lymph nodes, plus other surgeries to remove the areas where cancer has spread. Along with surgery, adjuvant chemo is also prescribed before and post-surgery. In some patients, hepatic artery infusion is also prescribed, especially when cancer has spread to the liver cells.
Surgery
Surgery is often the first line of treatment for colon cancer. The primary goal of surgery is to remove the tumor along with some surrounding healthy tissue. The type of surgery performed depends on the size and location of the tumor.
## Types of Surgery
Polypectomy: In cases where cancer is detected at an early stage and is confined to a polyp, a polypectomy may be performed during a colonoscopy. The polyp and some surrounding tissue are removed.
Partial Colectomy: For larger tumors, a partial colectomy may be necessary. This involves removing the section of the colon that contains the cancer, along with nearby lymph nodes. The remaining sections of the colon are then reconnected.
Total Colectomy: In advanced cases where cancer has spread significantly, a total colectomy may be required. This involves the removal of the entire colon, and an ostomy may be created to allow waste to exit the body.
Laparoscopic Surgery: Minimally invasive laparoscopic techniques can also be used for certain patients. This approach typically results in less pain, shorter recovery time, and smaller scars compared to traditional open surgery.
If the cancerous cells can’t be removed with surgery because of its increased size, or there are multiple cells, then chemo is prescribed before surgery. It shrinks the size of cancer, and then surgery is performed to remove it. Post-surgery chemo is prescribed again to kill the remaining cells. If there is a tumour in the liver, surgeons may opt for other treatment options to destroy the tumour, including embolization and ablation.
If the cancer spread is larger, which can’t be removed via surgery, chemo is the only treatment prescribed in such cases. Surgery is still required if the cancer is hindering the colon from performing. This type of surgical procedure can be prevented by putting a hollow metal or plastic tube called a stent into the colon while performing colonoscopy to keep the colon open. Surgeries like diverting colostomy or colectomy are performed to remove cancer that is blocking the colon.
Patients at Stage-4 Colon Cancer
Stage-4 are usually treated with both surgery and chemotherapy. Patients need to understand the surgery’s objective and learn whether it is performed to cure cancer or prevent it or alleviate the symptoms of cancer. With Stage-4 Colon Cancer are usually prescribed with targeted therapies and chemo in combination to control cancer.
The selection of best Stage-4 Colon Cancer treatment depends greatly on different factors, including overall health and any previous treatments the patients have undergone. For all advanced Colon Cancers, chemo or radiation therapy is used to prevent and alleviate the symptoms and chronic pain it causes. It shrinks the size of the tumours but never treats cancer permanently. If radiation therapy is prescribed to the patients, it is important to understand its prime goal.
Treatment Options for Recurring Colon Cancer
Recurring Colon Cancer means the type of cancer that tends to reoccur or come back after proper cancer treatment. The recurrent of the Colon Cancer can be in distant organs or local, which means it is near the area of previous tumour or cancer.
The treatment options for recurring colon cancer can be broadly categorized into systemic therapies, local therapies, and supportive care.
Systemic Therapies
Systemic therapies involve the use of medications that target cancer cells throughout the body. These include chemotherapy, targeted therapies, and immunotherapy.
1. Chemotherapy Chemotherapy remains a cornerstone treatment for recurring colon cancer. It typically involves a combination of drugs that work to kill cancer cells or inhibit their growth. Common regimens may include drugs such as fluorouracil (5-FU), leucovorin, and oxaliplatin. The specific chemotherapy regimen will depend on the individual’s previous treatments and overall health.
## Side Effects
Chemotherapy can lead to various side effects, such as nausea, vomiting, fatigue, hair loss, and an increased risk of infection. These side effects vary depending on the specific drugs used and the individual patient.
2. Targeted Therapies Targeted therapies focus on specific molecular targets associated with cancer. For colon cancer, drugs such as cetuximab and bevacizumab are often used. Cetuximab targets the epidermal growth factor receptor (EGFR), while bevacizumab inhibits blood vessel formation to tumors. These therapies can be used alone or in combination with chemotherapy, depending on the cancer’s genetic makeup and prior treatment history.
Common Targeted Therapies
Bevacizumab (Avastin): This drug blocks the growth of new blood vessels that tumors need to grow.
Cetuximab (Erbitux): Targets the epidermal growth factor receptor (EGFR) and is effective in patients with certain genetic profiles.
Panitumumab (Vectibix): Similar to cetuximab, it is used in patients with wild-type KRAS tumors.
## Side Effects
Common side effects of targeted therapies include skin rashes, diarrhea, and an increased risk of infection. These therapies are generally well-tolerated compared to traditional chemotherapy.
3. Immunotherapy Immunotherapy harnesses the body’s immune system to fight cancer. Immune checkpoint inhibitors, such as pembrolizumab and nivolumab, have shown effectiveness in patients with microsatellite instability-high (MSI-H) or mismatch repair-deficient (dMMR) tumors. These therapies help restore the immune system’s ability to detect and destroy cancer cells. Immunotherapy is particularly promising for patients whose cancer has not responded to traditional therapies.
## Common Immunotherapy Agents
Pembrolizumab (Keytruda): A PD-1 inhibitor that has shown effectiveness in MSI-H colon cancer.
Nivolumab (Opdivo): Another PD-1 inhibitor, often used in combination with ipilimumab.
## Side Effects
While immunotherapy can be effective, it may also cause immune-related side effects, such as inflammation of healthy organs (colitis, pneumonitis, etc.). Patients require careful monitoring during treatment.
Local Therapies
Local therapies are aimed at treating cancer that has recurred in a specific area. They may include surgery or radiation therapy.
1. Surgery Surgical intervention is an option for patients with localized recurrences, especially if the cancer has not spread extensively. The goal is to remove the tumor and any affected surrounding tissue. In some cases, surgeons may perform a partial colectomy or a more extensive procedure, depending on the tumor’s location and size. Surgery can also be considered for metastases, particularly in the liver, where resection may improve survival chances.
2. Radiation Therapy Radiation therapy uses high-energy rays to target and kill cancer cells. It is often employed in conjunction with other treatments. In cases of localized recurrence, radiation may be used to shrink tumors or alleviate symptoms. It can also be beneficial for patients who are not candidates for surgery.
## Types of Radiation Therapy
External Beam Radiation: The most common method, where radiation is targeted from outside the body.
Brachytherapy: Involves placing radioactive material directly into or near the tumor, though this is less common for colon cancer.
## Side Effects
Side effects of radiation therapy may include skin irritation, fatigue, diarrhea, and changes in bowel habits. Most side effects are temporary and improve after treatment ends.
Clinical Trials
Participation in clinical trials may provide access to cutting-edge therapies not yet widely available. Clinical trials test new drugs, combinations of existing treatments, or novel approaches like gene therapy and personalized medicine. Patients should discuss the possibility of enrolling in clinical trials with their healthcare team, as these studies can offer alternative options when standard treatments are no longer effective.
Palliative Care
Palliative care is an essential component of the treatment strategy for recurring colon cancer, especially in advanced stages. This approach focuses on improving the quality of life for patients by managing symptoms and providing psychological support. Palliative care teams can help address pain, nausea, fatigue, and emotional distress. Ensuring that patients receive comprehensive support throughout their treatment journey.
Treatment Option for Distance Recurring Cancer
If the Colon Cancer reoccurs in a distant site, it is likely to appear first in the liver. In such a condition, surgery is performed in most of the patients. Chemotherapy is prescribed to patients before surgery to shrink the tumours’ size, and then surgery is performed to remove the colon cancer. Embolization or ablation is the proven method to treat some of the liver tumours.
If the cancer spread is more and can’t be treated with surgery, then targeted therapies or chemo is prescribed. Most of the regimens are the same as Stage-4 disease. If the cancer is found to have traits during the laboratory tests, then another treatment option like immunotherapy is used to treat it.
The best treatment option depends on which drug you have used before the Colon Cancer recurrence. How long you have been using it and your overall health condition. Surgery is needed at some point to prevent the blockage of colon and spreading of local problems. Radiotherapy is prescribed to alleviate the symptoms. Recurring Colon Cancer is quite dangerous and difficult to cure.
Local Recurrence
If the Colon Cancer reoccurs locally, surgical procedure is performed, followed by chemotherapy to help patients live longer and cure cancer permanently. Locally reoccurred cancer can’t be removed with surgical procedures, then chemotherapy is the treatment option that is tried initially. If it manages to shrink the tumour’s size, the doctors will perform surgery to remove it. The surgery is followed by chemotherapy again to kill the remaining cells permanently.
Prevention
Some medications are proven to minimize the risk of precancerous Colon Cancer. Regular use of aspirin or related drugs reduces the risk of developing polyps or Colon Cancer. But it is not clear yet what is the right dose to consume and for what length it must be used to reduce the risk.
