Colorectal cancer

Hello Dr.
Hou: My brother underwent surgery for an artificial stoma at Taichung Veterans General Hospital over two years ago and has been on oral chemotherapy since then.
In early April of this year, due to the spread of cancer cells, he had his bladder and prostate removed and underwent another urethrostomy.
He has been frequently hospitalized due to infections.
In early August, he had another surgery because the wound from the April procedure, which was approximately 10x15 cm and deep to the intestines, had mostly regrown with cancerous cells, leading to persistent bleeding.
Electrocautery was ineffective due to tissue necrosis, and currently, there is no metastasis to other areas.
The attending physician stated that the only option now is to control the cancer through chemotherapy, and any new cancer growth would need to be surgically removed, as there are no other methods available.
He has been continuously undergoing chemotherapy, but his condition is still deteriorating.
Are there any other methods to control this? Is dietary modification currently feasible? How should his diet be managed? Thank you!

More Info

Managing advanced colorectal cancer, particularly in cases where the disease has progressed significantly and traditional treatments such as chemotherapy are not yielding the desired results, can be challenging. In your brother's situation, where he has undergone multiple surgeries and is experiencing complications, it is essential to explore all available options, including potential dietary changes and alternative treatments.

Treatment Options
1. Chemotherapy: As mentioned, your brother is currently undergoing chemotherapy. While it may not be effective in controlling the cancer, it is crucial to discuss with his oncologist the possibility of adjusting the chemotherapy regimen or considering other chemotherapy agents that may have a different mechanism of action.

2. Targeted Therapy: Depending on the specific characteristics of the cancer, targeted therapies may be an option. These treatments focus on specific pathways or mutations in cancer cells. Genetic testing of the tumor can help identify potential targets for therapy.

3. Immunotherapy: For some patients with colorectal cancer, particularly those with mismatch repair deficiency (dMMR) or microsatellite instability (MSI), immunotherapy can be an effective treatment option. This approach harnesses the body’s immune system to fight cancer.

4. Clinical Trials: Given the advanced nature of your brother's cancer, exploring clinical trials may provide access to cutting-edge therapies that are not yet widely available. Discuss with his oncologist about any ongoing trials that may be appropriate.

5. Palliative Care: If the focus shifts from curative treatment to quality of life, palliative care can be beneficial. This approach aims to relieve symptoms and improve the quality of life for patients with serious illnesses.

Dietary Changes
Diet can play a supportive role in cancer management, although it is not a substitute for medical treatment. Here are some dietary considerations that may help:
1. Balanced Nutrition: Encourage a diet rich in fruits, vegetables, whole grains, and lean proteins. These foods provide essential nutrients that can support overall health and immune function.

2. Hydration: Staying well-hydrated is crucial, especially if your brother is experiencing side effects from chemotherapy or has had surgeries that affect his fluid balance.

3. Small, Frequent Meals: If he has a reduced appetite or is experiencing nausea, small, frequent meals may be easier to tolerate than larger meals.

4. Limit Processed Foods: Reducing the intake of processed and high-sugar foods can help maintain better overall health and may reduce inflammation.

5. Consult a Dietitian: A registered dietitian specializing in oncology can provide personalized dietary recommendations based on your brother's specific needs, preferences, and treatment plan.

6. Nutritional Supplements: If he is struggling to meet his nutritional needs through food alone, consider discussing nutritional supplements with his healthcare team. However, it is essential to ensure that any supplements do not interfere with his cancer treatments.

Conclusion
While the situation is undoubtedly challenging, it is essential to maintain open communication with the healthcare team to explore all available treatment options and supportive measures. Dietary changes can complement medical treatment, but they should be tailored to your brother's individual needs and circumstances. Encourage him to focus on maintaining a positive outlook and quality of life during this difficult time.
