Objectives: To evaluate the efficacy and toxicity of paclitaxel and cisplatin alternating with paclitaxel and etoposide doublet regimen (TP/TE), for salvage of patients with high-risk gestational trophoblastic neoplasia (GTN).
Patients and methods: Twenty-four patients with GTN received TP/TE. Sixteen had failed previous chemotherapy including six with cisplatin-based regimens (group A) and eight changed to TP/TE because of prior treatment-induced toxic effects (group B).
Results: In group A, three patients (19%) achieved a complete response (CR) and five (31%) a partial response (PR). All CR and four PR patients remain alive with a median follow-up of 25 months (range 9–48). The eight patients failing TP/TE subsequently died. Thus, the overall survival of the 16 patients in group A was 44% (seven of 16), rising to 70% (seven of 10) if the six patients who had failed prior cisplatin-based chemotherapy were excluded. In group B, four patients were assessable for response (two CR, two PR) and six remain alive (median follow-up 19 months) giving an overall survival of 75%. TP/TE was well tolerated, with only one patient discontinuing therapy because of toxic effects.
Conclusion: TP/TE is an effective, well-tolerated, salvage treatment for relapsed patients who are heavily pretreated for GTN. Further studies of this regimen are warranted.
