Metastatic Seminoma (IGCCCG Intermediate) After Salvage Chemotherapy Failure — Next-Line Treatment
This protocol addresses patients with metastatic seminoma germ cell tumour classified as IGCCCG intermediate prognosis whose prior salvage chemotherapy did not achieve an adequate response, requiring escalation to the next treatment step.
Patient profile
Seminoma germ cell tumour, metastatic disease, IGCCCG intermediate prognosis group. All of the following criteria apply:
- Any primary site
- Nonpulmonary visceral metastases present
- Normal AFP (alpha-fetoprotein)
- Any hCG level
- Any LDH level
Previous treatment — insufficient response
Salvage chemotherapy (VIP, TIP, or GIP regimen) was administered but failed to achieve the required outcomes: normalization of serum tumour markers and complete or partial radiological response. Failure to reach these goals triggers escalation to this protocol.
Next-line treatment approach
An intensified, high-dose chemotherapy strategy is indicated at this stage — the complete regimen, sequencing, and full clinical guidance are available in the structured protocol below.

- All of the following criteria: Any primary site, Nonpulmonary visceral metastases, Normal AFP, Any hCG, Any LDH.
- HDCT with autologous stem cell support should be used although the prospect of cure is < 25%.
- When HDCT is used as a salvage treatment, sequential treatment cycles of high-dose carboplatin and etoposide (HD-CE) should be preferred to a single high-dose regimen as the former is associated with less toxicity-related deaths.
