Proton and Carbon-Ion Therapy in Korea
APIS helps international cancer patients identify relevant Korean hospitals and coordinates medical records, hospital review and treatment arrangements for proton or carbon-ion therapy.
Plan Early. Keep Your Treatment Options Open.
Explore Korean hospital options in parallel with treatment planning at home, including while insurance authorization or appeals are underway.
Systemic Therapy at Home. Particle Therapy in Korea.
Your home team may manage systemic treatment while a Korean hospital reviews how particle therapy fits your plan. Eligible patients may attend as outpatients. Preparation and treatment require separate scheduling.
Clinical Situations
When surgery or another local treatment is difficult, these situations can be reasons to ask what options remain.
Unresectable
The tumor cannot be completely removed by surgery. Radiation may still offer a way to treat the tumor area.
Example: A pancreatic tumor surrounds major blood vessels, making complete surgery difficult.
Pancreatic cancer and local treatmentRecurrent
Cancer has returned. Its location, spread and previous treatment affect which local treatments remain possible.
Example: Rectal cancer returns within the pelvis after surgery. The hospital reviews whether another operation or focused radiation could help.
Local pelvic recurrenceRe-irradiation
Another radiation course requires a review of the dose already delivered and the organs exposed.
Example: A pelvic recurrence lies in an area that previously received radiation. The old plan helps show how much more nearby bowel or nerves could tolerate.
Radiation after previous treatmentRadioresistant
Some tumor types respond less well to conventional radiation. Carbon ions have biological effects that can be useful in these settings.
Example: ACC that cannot be removed surgically may prompt review of carbon-ion therapy alongside other radiation options.
ACC and particle therapyClose to Critical Organs
Treatment needs to reach the tumor while limiting radiation to sensitive structures nearby.
Example: A skull-base tumor is close to the optic nerves or brainstem. The actual radiation plan shows whether normal-tissue exposure can be reduced.
Protecting nearby organsThe cancer type, disease extent, previous treatment and current health together guide the hospital’s review of these situations.
Clinical Guides by Cancer Type
Read the treatment questions and practical review considerations for these difficult cancers, or open the broader hospital program table.
Adenoid Cystic Carcinoma (ACC)
Carbon-ion and proton options, nerve involvement and recurrence after radiation.
Pelvic / Sacral Sarcoma
Why subtype, surgical options and nearby bowel or nerves matter.
Recurrent Rectal Cancer
Local pelvic recurrence, further surgery and previous pelvic radiation.
Korean Centers and Cancer Types

Hospital program tableProton & Carbon-Ion Therapy
These are external-beam radiation treatments. Their beams can concentrate dose at depth and reduce unnecessary radiation beyond the target.

Understanding the Bragg Peak
Radiation releases energy as it passes through tissue. X-rays deliver dose along the beam path, including beyond the tumor. A proton or carbon-ion beam releases much of its energy near the end of its planned range: the Bragg Peak.
Different beam energies cover the tumor’s depth. Reducing dose beyond it can help protect normal tissue, but the benefit depends on the tumor’s location and the actual plan.
Proton therapy
Protons can limit unnecessary normal-tissue exposure, which matters near sensitive organs and in children.
Carbon-ion therapy
Carbon ions add a higher biological effect that can matter for some relatively radioresistant tumors. This is separate from the Bragg Peak.
Proton vs Carbon-Ion Therapy explains X-rays, both particle beams and the effect of previous treatment.
How APIS Works
From understanding your case to arranging care in Korea and follow-up at home.
-
Patient & Physician Portal
Organize records and use AI-assisted explanations, released after APIS review, to understand the case and explore treatment options. Opening soon; until then, contact APIS directly.
-
APIS Coordination
APIS recommends hospitals for review and coordinates multi-center submission, responses, expected schedules and hospital estimates.
-
Hospital Review & Treatment in Korea
Hospital specialists review the case. If treatment is offered and you agree, preparation and treatment proceed in Korea.
-
Follow-up Care at Home
APIS coordinates records and follow-up instructions with your local team. We can help identify a local provider where possible.
APIS services and credentials include interpretation, medical-visa support and follow-up coordination.
Treatment Planning & Next Step
Compare your expected medical costs at home with the Korean hospital estimate, including travel, accommodation and follow-up. Confirm the proposed appointments before booking.
Preparation and treatment are separate stages. Treatment Time and Cost explains the hospital-specific schedules and what to budget.
