Key Questions to Ask Your Oncologist About Locally Advanced Colorectal Cancer

I'm glad you're preparing to have a thorough conversation with your care team. Here are the most important questions organized by category to help you understand your diagnosis and treatment options:

Understanding Your Diagnosis & Staging

  1. What exactly does "locally advanced" mean for my specific case?

    • Ask your doctor to explain the TNM staging (Tumor size, Node involvement, Metastasis status) so you understand how far the cancer has spread within your abdomen and to nearby lymph nodes.
  2. Has my tumor been tested for specific genetic mutations (KRAS, BRAF, MSI/dMMR)?

    • These tests are important because they can identify whether your cancer might respond to targeted therapies or immunotherapy. According to NCCN Guidelines for colorectal cancer, molecular profiling is increasingly standard for treatment planning.
  3. What is the goal of my treatment—is it curative or palliative?

    • Understanding whether the goal is to cure the cancer, shrink it before surgery, or manage symptoms will help you set realistic expectations.

Treatment Planning & Options

  1. What is my treatment plan, and in what order will treatments happen?

    • For locally advanced colorectal cancer, doctors typically consider combinations of chemotherapy, radiation, and surgery. Ask specifically:
      • Will I receive chemotherapy before surgery (neoadjuvant therapy)?
      • Will I need radiation therapy?
      • When will surgery be scheduled?
  2. Am I a candidate for neoadjuvant therapy (treatment before surgery)?

    • Research shows that pre-surgical treatment can help shrink tumors and improve surgical outcomes. Ask why or why not this applies to your case.
  3. What chemotherapy regimen are you recommending, and why?

    • Common regimens include FOLFOX or CAPOX. Ask about:
      • How many cycles you'll receive
      • The expected timeline
      • Why this specific regimen for your tumor
  4. Will I need radiation therapy? If so, what type and how many treatments?

    • Radiation can be delivered in different ways (external beam, intensity-modulated, etc.). Understanding the specifics helps you prepare.

Side Effects & Managing Treatment

  1. What side effects should I expect from chemotherapy, radiation, and/or surgery?

    • Ask about both short-term (during treatment) and long-term effects
    • Common chemotherapy side effects include nausea, fatigue, diarrhea, and neuropathy (numbness in hands/feet)
    • Ask specifically: "What can we do to manage these side effects?"
  2. Are there medications or supportive care options to help with side effects?

    • Your team can often prevent or reduce side effects with anti-nausea medications, dietary changes, or other interventions
  3. Should I be exercising during treatment? Can you refer me to a physical therapist or prehabilitation program?

    • Research shows that staying active before and during cancer treatment can improve outcomes and reduce fatigue
  4. Should I see a nutritionist or dietitian?

    • Proper nutrition is critical during cancer treatment to maintain strength and support healing

Monitoring & Knowing If Treatment Is Working

  1. How will we know if the treatment is working?

    • Ask about:
      • Blood tests (tumor markers like CEA)
      • Imaging scans (CT, MRI) and how often
      • Physical exams
      • Timeline for reassessment
  2. What happens if the cancer doesn't respond to the initial treatment plan?

    • Understanding backup options gives you peace of mind

Clinical Trials & Newer Options

  1. Are there clinical trials available for my specific situation?

    • Clinical trials may offer access to newer treatments. Ask:
      • What trials match my diagnosis and stage?
      • What would participation involve (travel, time commitment)?
      • Are there financial assistance programs?
  2. Are there any targeted therapies or immunotherapies I should know about based on my tumor's genetic profile?

    • Depending on your mutation status, newer treatment options may be available

Surgery & Recovery

  1. What type of surgery do you recommend, and what will recovery look like?

    • Ask about:
      • Whether the surgery will be open or minimally invasive (laparoscopic)
      • Expected hospital stay
      • Time before returning to normal activities
      • Potential complications and how they're managed
  2. Will I need a colostomy or ileostomy (external pouch)?

    • This depends on tumor location. If yes, ask about support resources and adjustment

Your Overall Health & Quality of Life

  1. How will treatment affect my daily life—work, family, activities?

    • Understanding practical impacts helps you plan ahead
  2. What support services are available to me and my family?

    • Ask about:
      • Counseling or mental health support
      • Support groups
      • Nutritional support
      • Financial assistance programs
  3. Who should I call if I have questions or concerns between appointments?

    • Know how to reach your care team in an emergency

Follow-Up & Long-Term Monitoring

  1. What will follow-up care look like after treatment ends?

    • Ask about:
      • Frequency of scans and blood tests
      • How long surveillance continues
      • Signs/symptoms to watch for
  2. Are there lifestyle changes I should make to reduce recurrence risk?

    • Exercise, diet, smoking cessation, and other factors may help

Practical Tips for Your Appointment

Bring a notebook or recording device (ask permission first) to capture details
Bring a trusted family member or friend to help listen and take notes
Write down your questions beforehand so you don't forget them
Ask your doctor to explain anything you don't understand—there are no "stupid" questions
Request written summaries of your treatment plan
Ask for reliable resources (websites, organizations) for more information


Authoritative Resources for More Information

According to NCCN Guidelines for Colorectal Cancer and American Cancer Society recommendations, patients with locally advanced colorectal cancer benefit from:

  • Comprehensive molecular testing of their tumor
  • Multidisciplinary team evaluation (surgery, medical oncology, radiation oncology)
  • Discussion of clinical trial options at every stage

The National Cancer Institute (NCI) and American Society of Clinical Oncology (ASCO) also provide evidence-based information about colorectal cancer treatment at cancer.gov and cancer.net.
