Colorectal cancer treatment is highly individualized and based on several clinical factors, including cancer stage, tumor location, molecular characteristics, and overall patient health. At Cancer Care Northwest, treatment planning for patients across the Inland Northwest follows a multidisciplinary, evidence-based approach designed to deliver coordinated and personalized oncology care.
Before treatment begins, a comprehensive evaluation is conducted to determine the most appropriate course of care. This process typically includes imaging, pathology review, and, when indicated, biomarker testing.
Key factors that guide treatment decisions include:
This individualized assessment ensures that each patient receives a treatment plan aligned with current oncology standards and clinical guidelines.
Surgery is often the primary treatment for early-stage colorectal cancer. The goal of surgical intervention is to remove the tumor along with nearby lymph nodes to reduce the risk of spread or recurrence.
Common surgical procedures include:
For many patients with Stage I, II, and some Stage III colorectal cancers, surgery may be the first and most effective treatment option. Robotic-assisted surgical techniques may be utilized when clinically appropriate.
Hyperthermic intraperitoneal chemotherapy (HIPEC) is an advanced treatment used for select patients with colorectal cancer that has metastasized to the peritoneal cavity. HIPEC at Cancer Care Northwest is performed in conjunction with cytoreductive surgery to remove visible tumor deposits before circulating heated chemotherapy within the abdomen to target microscopic disease. This approach allows for high local chemotherapy concentrations while minimizing systemic toxicity. Surgical oncologist Dr. Rebecca Kirschner works within a multidisciplinary team to carefully evaluate patient eligibility based on disease distribution, tumor biology, and overall health status. For appropriately selected patients, HIPEC may offer improved disease control, and, in some cases, extended survival compared to systemic therapy alone.
Chemotherapy plays a central role in the treatment of colorectal cancer, particularly in high-risk Stage II , Stage III and advanced-stage disease. These systemic medications target rapidly dividing cancer cells and help reduce the risk of recurrence. Treatment plan is very personalized and individualized based on biomarker testing.
Chemotherapy may be used:
Radiation therapy is more frequently used in rectal cancer than colon cancer. It may be recommended:
Advanced radiation techniques allow for precise targeting of cancerous tissue while minimizing exposure to surrounding healthy structures.
Targeted therapies are designed to treat specific molecular features of colorectal cancer cells. These therapies are often used in advanced or metastatic disease and are guided by tumor biomarker testing.
Targeted treatments may include therapies directed at EGFR, VEGF, BRAF pathways, or KRAS signaling when clinically indicated. Molecular profiling helps oncology teams select therapies that are most likely to be effective for each individual patient.
Immunotherapy may be an option for patients whose tumors exhibit microsatellite instability-high (MSI-H) or mismatch repair deficiency (dMMR). These treatments enhance the immune system’s ability to recognize and attack cancer cells and are most commonly used in advanced-stage colorectal cancer.
Throughout treatment, patients undergo regular monitoring through imaging, laboratory testing, and clinical evaluations. This allows oncology providers to assess treatment response, manage side effects, and adjust therapy as needed.
Guidelines supported by organizations such as the American Society of Clinical Oncology inform ongoing treatment and monitoring practices.
Treatment options for colorectal cancer may include surgery, chemotherapy, radiation therapy, targeted therapy, and immunotherapy. At Cancer Care Northwest, a multidisciplinary and personalized approach ensures that patients in the Inland Northwest receive evidence-based care tailored to their specific diagnosis, stage, and overall health needs.
