Cancer of Unknown Primary (CUP)

For cancer of unknown primary (CUP), the path forward comes from thorough workup and board review. Our Doruk Oncology team walks it with you.

HIGHLIGHTS

What stands out in this treatment

Central Role of the Council

When the primary cannot be found, the decision is not left to one physician; pathologist, medical oncologist, radiologist, nuclear medicine and oncologists decide together.

Comprehensive Imaging

Whole-body assessment led by PET-CT investigates the possible primary focus and spread of disease.

Origin Search with Immunohistochemistry

Broad immunohistochemistry panels systematically investigate clues to the tissue's origin.

Molecular Profiling / Gene Expression

Molecular profiling and gene expression analysis estimate the likely origin and identify targets to guide treatment.

Origin-Directed Systemic Therapy

Immunotherapy and targeted therapy options directed at the estimated primary are evaluated by the tumor board.

Internationally Recognized Team and International Patient Support

A high-volume experienced team delivers JCI-standard care with end-to-end support for international patients.

Insurance & agreements

Transparent payment with contracted institutions and private insurers, at home and abroad.

Accommodation & rooms

Companion-friendly modern patient rooms and in-city accommodation support.

International patient services

Visa, airport transfer and 24/7 multilingual medical interpreters.

Transparent, guaranteed price

A quote prepared from your medical information; no extra charge for the treatments it covers.

TREATMENT TIMELINE

From day one to discharge

The timeline below is an average and varies by patient, diagnosis and clinical status. Exact timing and all included services are detailed in your personalized treatment offer.
Step 1
Application and comprehensive imaging — Existing biopsy, images and reports are shared; assessment is led by PET-CT.
Step 2
Pathology and immunohistochemistry — Origin investigation in the metastatic tissue with a broad immunohistochemistry panel.
Step 3
Molecular profiling / gene expression — Estimation of the likely origin and identification of molecular targets.
Step 4
The council’s central decision and personalized plan — All findings are reviewed in the council; origin-directed systemic therapy and, if needed, local control are planned.
Step 5
Treatment and follow-up — The plan is delivered; follow-up with response assessment, re-imaging and tele-oncology support.
Every treatment offer is presented in full detail — accommodation, transfer, interpreter and follow-up included — clearly stating what is covered.
