Colon cancer ranks among the most prevalent cancers worldwide. Colon cancer is a significant health challenge, affecting thousands each year. One common treatment approach for colon cancer is chemotherapy. This detailed guide explains the process and expectations associated with 12 cycles of chemotherapy for colon cancer, aiming to offer insights and support for those undergoing or considering this treatment.
What is Colon Cancer?
Colon cancer, also known as colorectal cancer, originates in the large intestine or rectal area, forming initially small, noncancerous (benign) lumps or harmless groups of cells known as polyps. Over time, some of these polyps can transform into malignant (cancerous) cells.
But what does this mean for you? Let's break down what colon cancer is and how it affects your body to better understand the treatment ahead.

Over time, these polyps can become cancerous, growing deeper into the colon walls and possibly spreading to other body parts. Early detection of these polyps through screenings like colonoscopies is key because it can prevent them from turning into cancer.
This cancer is most common in older adults, although it can occur at any age. Early detection is crucial because it greatly improves the chances of successful treatment with therapies, including surgery, chemotherapy, and radiation.

Stages of Colon Cancer
Colon cancer progresses through several stages, each affecting treatment options and outcomes. Here's a simplified breakdown of each stage:
- Stage 0 (Carcinoma in Situ): The earliest stage where abnormal cells are only in the inner lining of the colon or rectum. Removal is usually done through a colonoscopy.
- Stage I: Cancer has grown into deeper layers but hasn't spread outside the colon or to lymph nodes. Surgery is typically used to remove the affected part.
- Stage II: Cancer has spread through the colon wall but hasn't reached any lymph nodes. Treatment usually involves surgery, and sometimes chemotherapy, to prevent recurrence.
- Stage III: Cancer has spread to nearby lymph nodes but not to distant sites. Treatment involves surgery, followed by chemotherapy and sometimes radiation to kill any remaining cancer cells.
- Stage IV: The most advanced stage, where cancer has spread to distant organs like the liver or lungs. Treatment options may include surgery, chemotherapy, targeted therapy, and palliative care to ease symptoms and improve quality of life.
Now, you might be wondering... How exactly do we prepare for chemotherapy and what are the first steps? Here’s what you need to know.
Preparing for Chemotherapy
Preparing for chemotherapy involves several important steps to ensure the treatment is as effective and manageable as possible.
- Complete Health Check-Up: Get a full medical examination to tailor your chemotherapy plan and ensure your body can handle the treatment.
- Discuss Medical History: Discuss your health issues and treatments with your doctor to prevent complications.
- Learn About Side Effects: Understand the potential side effects of your chemotherapy drugs so you can be prepared to manage them.
- Undergo Diagnostic Tests: Have necessary blood tests and possibly organ function tests to confirm your readiness for chemotherapy.
- Make Dietary Changes: Based on the advice of a nutritionist, adjust your diet to help strengthen your body and lessen side effects.
- Arrange Support: Set up a support network and plan logistics like transportation and home help for treatment days.
Chemotherapy involves administering specific drugs to target cancer cells. The 12-cycle regimen signifies a prolonged course aiming to eradicate cancer cells, prevent recurrence, and enhance survival. Chemotherapy for colon cancer often includes drugs like 5-fluorouracil (5-FU), oxaliplatin, irinotecan, and capecitabine. These agents disrupt cancer cell growth and division. Let's learn how the treatment goes.
12 Cycles of Chemotherapy for Colon Cancer
Doctors often prescribe 12 cycles of chemotherapy to treat colon cancer. This helps the chance of remission. Here's a brief explanation of each cycle:
Cycle 1 is the introduction of chemotherapy drugs to target and kill cancer cells, with initial doses adjusted based on the patient's health and cancer stage.
Cycle 2 is for evaluating the initial response to drugs. Adjustments may be made based on side effects and observed effectiveness.
Cycle 3 will continue the treatment. Doctors will monitor blood counts and the patient's health. This is to ensure the patient can tolerate treatment.
Cycle 4 involves assessing tumor response through imaging tests. Doctors may adjust drugs based on results.
Cycle 5 has 2 tasks. The first is to maintain the drug regimen. It focuses on managing side effects and keeping the dosage effective.
Cycle 6 is the midway evaluation of treatment progress. Changes may be made to improve outcomes.
Cycle 7 will feature continued therapy. The therapy will have ongoing changes. The goal is to kill cancer cells and manage health impacts.
Cycle 8 will include more imaging and tests to track cancer. You will also continue the adjusted chemo.
Cycle 9 is an ongoing treatment. It is under close medical supervision to ensure a sustained response to therapy.
Cycle 10 is for preparing to conclude. It will focus on assessing any remaining cancer.
Cycle 11 is the second-to-last cycle. It aims to keep the gains in cancer treatment and prepare for the possible end of chemotherapy.
Cycle 12 is the final cycle. It has a big evaluation to decide the next steps. The decision will be based on the results after chemotherapy.
Each cycle is a few weeks long. This gives the body time to recover between treatments.
Chemotherapy is a powerful cancer treatment. But, it often causes side effects. These are due to its impact on fast-dividing cells in the body, not just the cancer cells.
Side Effects of Chemotherapy
What to Expect During and After Chemotherapy
During Chemotherapy:
- Treatment Schedule: A series of treatments over weeks or months, with breaks in between.
- Administration: Drugs given intravenously (IV) or as pills.
- Monitoring: Regular health checks to adjust treatment as needed. Also, access to counselling and nutritional advice.
- Side Effects: Medications and strategies to manage effects like nausea and fatigue.
After Chemotherapy:
- Follow-up Care: Regular doctor visits to monitor health and any signs of cancer.
- Recovery: Gradual improvement of side effects; hair and energy levels return.
- Long-Term Monitoring: Check for long-term side effects over the years.
- Lifestyle Guidance: Advice on diet and exercise to maintain health and prevent recurrence.
- Emotional Support: Ongoing access to mental health services and support groups.

Survival Success Rates
The 5-year survival rate for stage II colon cancer can exceed 80% with appropriate treatment, including chemotherapy. However, some people may live longer than 5 years following their diagnosis.
- A study published in Frontiers in Oncology reported that the 5-year survival rates for stage II colon cancer were 69.9%
- Colorectal cancer is the third most diagnosed cancer globally. In 2020, approximately 1,880,725 people were diagnosed with colorectal cancer cases.
- The overall 5-year relative survival rate for people with colon cancer is 63%. If the cancer is diagnosed at a localized stage (stage I or II), the survival rate increases to 91%.
However, it’s essential to note that survival rates can vary due to various factors, including access to healthcare, treatment options, and individual patient characteristics.
Recent Insights
Doctors have been studying how long chemotherapy should last for treating certain types of colon cancer. They found that for stage III and high-risk stage II colon cancer, having chemotherapy for just three months works as well as the usual 6 month treatment. This means people have a similar chance of surviving without recurrence of cancer.
Doctors must customize treatment based on each person's situation. For stage IV cancer, where the cancer has spread to the liver but surgery might still be an option, doctors might suggest a shorter course of chemotherapy first. Then, they'll check if surgery is possible afterwards.
Conclusion
Undergoing 12 cycles of chemotherapy is tough. But, it's often a vital treatment for colon cancer. While challenging, the potential for a positive outcome can make the process worthwhile. Support from healthcare providers, family, and cancer support groups is crucial. It helps in navigating this journey.
