Colorectal Cancer Treatment: Treatment Strategies from Early to Advanced Stages

Kapanlagi.com - Colorectal cancer often appears without prominent signs, like a ghost lurking in silence. This condition makes early detection crucial so that treatment can be carried out before the cancer spreads to other parts of the body. Unfortunately, many people still ignore early symptoms, only to face a condition that has already reached an advanced stage.

Treatment for colorectal cancer is not something to be taken lightly. Every step must be tailored to the severity and condition of each patient. From surgical procedures to drug therapies, all play an important role in suppressing the growth of cancer cells. The earlier cancer is detected, the greater the chances for patients to return to health.

Most cancer cases, including colon cancer, do not show symptoms in the early stages. Therefore, it is important for us to conduct early detection so that we can address this disease before cancer cells spread further.

1. Initial Examination Determines Type and Stage of Cancer

The initial step in combating colorectal cancer begins with a thorough examination to identify the type of cancer and the extent of its spread. Doctors typically recommend a colonoscopy to inspect the interior of the large intestine and rectum; if polyps are detected, some will be removed and tested in a laboratory to check for malignancy.

Additionally, imaging tests such as CT scans, MRIs, or PET scans are also performed to confirm whether cancer cells have spread to other organs. Blood tests, including CEA (Carcinoembryonic Antigen), play a role in detecting the presence of cancer. Once all information is gathered, the doctor will determine the stage of cancer, ranging from early stage (stage 0) to advanced stage (stage IV).

By understanding the stage and characteristics of the cancer cells, doctors can design the most effective combination of treatments, considering that each stage requires a different approach, whether local or systemic treatment.

2. Surgery as the Primary Treatment for Early Stage

For patients in the early stages of colon cancer, surgery is the primary step relied upon to remove the infected part of the large intestine or rectum. This process, known as resection, is often followed by reconnecting the healthy parts of the intestine through anastomosis techniques.

However, if only a small portion of healthy intestine remains, the doctor may have to create an artificial opening in the abdominal wall, called a colostomy, to divert feces into an external bag. Although this sounds invasive, this procedure can actually provide a better chance of survival and improve the quality of life for patients.

The decision to perform surgery greatly depends on the extent of cancer cell spread and the overall health condition of the patient.

3. Chemotherapy and Radiotherapy to Attack Cancer Cells

When cancer has spread or reached intermediate to advanced stages, doctors typically recommend two main approaches: chemotherapy and radiotherapy. Chemotherapy utilizes special medications, either through injections or orally, to destroy cancer cells circulating in the body, with key weapons like capecitabine, oxaliplatin, and irinotecan.

On the other hand, radiotherapy uses high-intensity radiation beams to disrupt cancer cells at specific locations, either externally or internally, depending on the size and position of the tumor. These two methods are often combined to enhance treatment effectiveness, especially in managing rectal cancer.

However, the treatment journey is not without challenges; patients must be prepared to face side effects such as nausea, hair loss, and extreme fatigue. Therefore, close medical supervision becomes crucial during the therapy process.

4. Targeted Therapy and Immunotherapy as Modern Approaches

In recent years, the medical world has witnessed significant advancements in the treatment of advanced colorectal cancer thanks to the emergence of targeted therapy and immunotherapy. Targeted therapy, known for its ability to selectively inhibit the growth of cancer cells without harming healthy cells, has become a mainstay with drugs such as bevacizumab and cetuximab.

On the other hand, immunotherapy plays a crucial role in strengthening the immune system, enabling it to recognize and fight cancer cells, especially for patients with certain genetic mutations such as MSI-H or dMMR. Given that not all patients can receive this therapy, genetic testing is often conducted beforehand to ensure compatibility.

According to the American Cancer Society, this systemic therapy approach has become a crucial option, especially when cancer has spread to various parts of the body, while also opening up hope for longer life and better quality of life.

5. Continuing Support and Palliative Care

Cancer treatment is not the end of the journey, but rather the beginning of a new chapter filled with challenges. After undergoing medical procedures, many patients require ongoing support, both physically and mentally. Proper nutrition, psychological support, and social guidance become essential pillars in their recovery process.

Especially for patients with terminal cancer, palliative care becomes a primary focus, aimed at alleviating pain and managing symptoms, while also providing the much-needed emotional support. Hospice programs are also ready to assist those who are expected to have a life expectancy of less than six months.

The American Cancer Society emphasizes that supportive care is crucial for maintaining the quality of life for patients, whether they are still undergoing active treatment or have chosen to discontinue it. In this journey, open and honest communication between patients and the medical team is key to finding the best options for their well-being.
