Colorectal Cancer Treatment Options: What Are Your Choices?

Colorectal cancer treatment varies based on the stage of the cancer, overall health, and patient preferences. The main treatment options include surgery, chemotherapy, and radiation therapy, often used in combination to maximize effectiveness.

Surgery

Surgery is often the first-line treatment for localized colorectal cancer. It involves removing the tumor and surrounding tissues to achieve clear margins and prevent spread.

  • Types of surgery may include colectomy (removal of part or all of the colon) or rectal resection.
  • Surgery can be curative in early-stage cancers and may be combined with other therapies in advanced stages.

Chemotherapy

Chemotherapy uses drugs that kill rapidly dividing cancer cells throughout the body and is a key treatment for many colorectal cancers.

  • Adjuvant chemotherapy is given after surgery to eliminate remaining cancer cells and reduce recurrence risk.
  • Neoadjuvant chemotherapy may be given before surgery to shrink tumors.
  • Common drug regimens include 5-fluorouracil (5-FU), oxaliplatin, irinotecan, and capecitabine. Combination therapies like FOLFOX and FOLFIRI improve survival.

Radiation Therapy

Radiation therapy uses high-energy X-rays to destroy cancer cells and is mainly used for rectal cancer, either before surgery to shrink tumors or after to reduce recurrence.

  • It can be combined with chemotherapy for better effect (chemo-radiation).
  • Side effects include fatigue and gastrointestinal discomfort, which are managed carefully by the cancer care team.

Emerging and Targeted Therapies

Newer treatments such as immunotherapy and targeted therapy are increasingly used for metastatic or advanced colorectal cancers. These therapies aim to boost the immune response or target specific mutations in cancer cells, offering personalized treatment approaches.

Multidisciplinary Approach

Optimal colorectal cancer treatment involves a team of surgeons, medical oncologists, radiologists, and allied health professionals. Treatment plans are tailored to individual needs, balancing effectiveness, side effects, and quality of life.

Colorectal cancer care incorporates surgery, chemotherapy, radiation, and emerging targeted therapies. Understanding your options and working closely with your healthcare team in Singapore ensures the best personalized treatment strategy tailored to your diagnosis.
