How effective is chemotherapy for germ cell tumour?

Germ cell tumours include different subtypes, such as seminoma and teratoma, and they can arise in the testicle, ovary or another part of the body. Some respond quickly to chemotherapy, while a remaining mass may need surgery or further assessment. Blood tumour markers can help the team follow treatment because their levels may change as active tumour tissue responds. Imaging, examination and marker trends are interpreted together. A response does not always mean every abnormal area has disappeared, and the plan may continue after symptoms improve.

Before treatment, ask about fertility preservation, since chemotherapy can affect sperm or egg production. Discuss the medicines, planned cycles, blood tests and scans, and tell the team about hearing problems, kidney conditions, numbness, or other medicines. Take anti-sickness treatment as directed and keep a record of fever, pain, appetite and new symptoms. Do not delay a call about infection symptoms, because low white-cell counts can make infections serious.

Seek urgent advice for fever, shaking chills, severe vomiting, reduced urine, new hearing changes, worsening numbness, unusual bleeding, or breathlessness. Emergency care is appropriate for collapse, severe breathing difficulty, confusion, or facial and throat swelling after treatment.

Which germ cell tumour subtype do I have? How will markers and scans be used? Should I arrange fertility preservation before treatment? Could surgery be needed after chemotherapy?
