摘要
We investigated the pattern of relapse after chemotherapy in patients with high-risk germ cell tumor (GCT) to critically review common follow-up procedures including close monitoring of serum tumor markers and radiologic procedures.645 patients received first-line (434 patients) or salvage platinum-based (211 patients) high-dose chemotherapy in three multicenter trials. Retrospective analysis comprised 77 patients after first-line and 61 after salvage chemotherapy, who had achieved at least a partial remission but progressed afterwards.At relapse, 24% of the patients presented with an isolated elevation in serum tumor markers, 26% with pathologic radiologic confirmation with negative tumor markers, and 42% with elevated tumor markers and radiologically confirmed progression. Relapse was detected by clinical symptoms in 8%. 46% relapsed within 3 months and 97% within 2 years. Relapse pattern did not correlate with tumor marker status or metastasis location prior to chemotherapy, line of chemotherapy, response status after chemotherapy or time point of relapse.In high-risk GCT patients, relapse after chemotherapy is detected either by tumor marker elevation alone, radiologic imaging alone or both, in one third each. Close monitoring including serum tumor markers, radiologic imaging and clinical examination appears warranted within the first 2 years.
