Testicular nonseminoma (NSGCT)
Also called Testicular nonseminomatous germ cell tumor
Testicular nonseminomatous germ-cell tumors include several histologies, such as embryonal carcinoma, yolk-sac tumor, choriocarcinoma and teratoma, often in mixed tumors. Stage, tumor markers and the specific components guide treatment.
Other names and abbreviations
NSGCT, nonseminoma, testicular nonseminomatous germ cell tumor, testicular germ cell cancer, embryonal carcinoma, yolk sac tumor, choriocarcinoma, mixed germ cell tumor, Nonseminomatous germ cell tumour of the testis, mixed germ cell tumour when mixed histologies are present
In short
- Testicular nonseminomas are germ cell cancers of the testicle, often made of mixed tumor types, that mainly affect teens and younger adult men.
- Treatment starts with surgery on the testicle, then may mean close follow-up, platinum-based chemotherapy or more surgery, depending on risk.
- For some cancers that come back or do not respond, high-dose chemotherapy with a return of the patient's own stem cells is an established option, and no donor is normally needed.

Where transplant fits
Very strong drug treatment given in large doses, often to kill cancer cells. It also destroys the bone marrow and can cause other serious side effects. A stem cell transplant usually follows to rebuild the marrow. with Coming from the patient's own body. In an autologous transplant, the patient's own stem cells are collected and stored, then given back after high-dose treatment. It does not use a donor. is an established option in selected When a disease comes back after a period of getting better. Relapsed disease has returned after treatment helped for a time. or Describes a disease that does not respond to treatment. It may resist treatment from the start, or treatment may stop working along the way. germ-cell tumor settings. The patient’s own cells restore blood production after chemotherapy. A registry donor is not normally needed, and A treatment that gives a patient healthy blood-forming stem cells through a vein. The cells travel to the bone marrow and replace faulty marrow or marrow damaged by treatment. They can come from the patient or a donor. is not routine for every newly diagnosed testicular cancer.
Treatment depends on the exact diagnosis, disease stage, prior treatment and the person’s health.
Key facts
- Who it affects
- These tumors mainly affect adolescents and younger adult males.
- Usual treatment
- Treatment begins with testicular surgery and may involve surveillance, platinum-based chemotherapy or further surgery according to risk. Relapsed disease can be treated with conventional-dose salvage chemotherapy or a high-dose approach in an expert center.
- Cells used in a transplant
- The patient’s own collected blood-forming cells for autologous stem cell rescue, when that procedure is appropriate.
- Where a donor fits
- Limited transplant role

Other patients are waiting for a match.
Most people with testicular nonseminoma (NSGCT) are treated without a registry donor. Many people with other blood cancers and blood disorders need a donor who is a stranger.
Join the registry
JBF points you to the official registry that serves your country. It explains who can join and what donation involves.
Help a family run a drive
If someone you love needs a donor, a registration drive can add many potential donors at once, for them and for others.
Support this work
Gifts to the Jada Bascom Foundation support donor-awareness education like this guide, community outreach, drive planning and referrals to official registries.
