How Much Does One Round of Chemotherapy for Colorectal Cancer Cost? (2026 Update)

In short, the cost of one round (one cycle) of chemotherapy for colorectal cancer varies depending on the type of drug, number of cycles, and stage, so there is no fixed amount in our notes — the actual cost is confirmed only through a hospital-issued estimate. However, the remote review (pre-arrival review) fee of KRW 1,000,000 (about US$730) is a fixed amount set by the site, and it is deducted from treatment costs when a treatment contract is signed.

Key Takeaways

• There is no fixed price for a single round of chemotherapy in the knowledge notes — the total depends on the drug regimen and number of cycles, and the actual amount is confirmed only through a hospital estimate.
• The remote review (pre-arrival review) fee is fixed at KRW 1,000,000 (about US$730). If you sign a treatment contract after the remote review, this amount is deducted from your treatment costs.
• For stage 3 colon cancer (lymph node metastasis) and stage 2 with risk factors, the typical course is several months of adjuvant chemotherapy after surgery.
• For stage 4 or recurrent colorectal cancer, systemic chemotherapy is the mainstay, with targeted agents or immune checkpoint inhibitors added depending on RAS, BRAF, MSI, and HER2 results.
• Korea's 5-year relative survival rate for colorectal cancer is 75.6% (National Cancer Registration Statistics, 2019–2023) — this is a nationwide figure, not specific to any one hospital.

Why isn't the cost of chemotherapy given as a fixed amount in advance?

• Colorectal cancer chemotherapy varies by patient in both drug regimen and number of treatment cycles, so the total cost for what is nominally the "same" chemotherapy can differ significantly.
• Depending on stage, colon cancer patients may receive several months of adjuvant chemotherapy after surgery, while stage 4 or recurrent colorectal cancer patients often undergo longer systemic chemotherapy, sometimes combined with targeted therapy or immunotherapy — meaning the number of cycles itself varies from patient to patient.
• For this reason, the notes do not list a set price. Costs are confirmed only through a hospital estimate that breaks down tests, surgery, hospitalization, and medication costs, as well as interpretation, lodging, and transportation.

How do the remote review and treatment contract process work?

• Step 1: Remote review (pre-arrival review) — Submit your imaging (CT scans, and pelvic MRI for rectal cancer), colonoscopy photos and written opinion, pathology report, and biomarker test results such as MSI/MMR, RAS, BRAF, and HER2. You will receive a written opinion for a fee of KRW 1,000,000 (about US$730).
• Step 2: Hospital estimate — Based on the written opinion, the hospital issues an estimate itemizing tests, surgery, hospitalization, and medication costs, as well as interpretation, lodging, and transportation.
• Step 3: Treatment contract — If you sign a treatment contract, the KRW 1,000,000 remote review fee is deducted from your treatment costs.
• Step 4: Treatment progression — Chemotherapy scheduling before and after surgery is determined by stage, and blood tests checking white blood cell and platelet counts determine whether the next cycle proceeds.
• Step 5: Follow-up management — You may also be offered an option, included in the estimate, to start the first cycle in Korea and continue the remaining cycles in your home country.

What side effects can occur during chemotherapy, and when should you contact medical staff?

• Nausea and vomiting affect about 70–80% of patients, typically appearing 1 to 8 hours after administration and lasting up to a week (National Cancer Information Center).
• White blood cell counts typically begin to drop in week 1, reach their lowest point in week 2, and recover by week 3 (National Cancer Information Center).
• If your body temperature reaches 38°C or higher, or you experience severe chills, contact your medical team immediately regardless of the time of day; if you cannot reach them, go to the emergency room.
• Numbness and tingling in the hands and feet (peripheral neuropathy) may persist after treatment ends or gradually improve, depending on the drug and dosage. If symptoms begin, consult your medical team.

FAQ — Do I need to receive all post-surgery chemotherapy in Korea?

No. You can be offered an option, along with your estimate, to start the first cycle in Korea to monitor for side effects and continue the remaining cycles in your home country, or to extend your stay in Korea. For stage 3 colon cancer and stage 2 with risk factors, several months of adjuvant chemotherapy after surgery is typical.

FAQ — Can treatment costs be estimated even for stage 4 or recurrent cases?

If the metastatic site can be surgically removed, chemotherapy may be combined with metastasis resection with the goal of cure. If it cannot be removed, systemic chemotherapy becomes the main approach, with targeted therapy or immune checkpoint inhibitors added depending on RAS, BRAF, MSI, and HER2 results. Because this combination differs for each patient, costs can only be determined through a hospital estimate issued after the remote review opinion.
