Abstract

Background

The aim of this study was to assess the efficacy of radio-frequency ablation (RFA) for metastatic lung or liver tumors of germ cell tumors (GCTs) after chemotherapy.

Methods

RFA with computed tomography guidance and monitoring was performed in 24 patients with 48 metastatic lung or liver tumors of GCTs. Group A consisted of 9 patients with tumor marker normalization after salvage chemotherapy and group B consisted of 15 patients without tumor marker normalization in spite ofintensive treatment.

Results

Out of 48 tumors, 41 tumors in 21 patients were evaluated for the efficacy of the RFA treatment. Of the 41 tumors, successful ablation was achieved in 34 (82.9 %). The patients in group A had significantly better survival than the patients in group B (p = 0.0003). In group A, all 9 patients are still alive with no evidence of disease (NED). Patients with a solitary tumor had significantly better survival than those with multiple tumors (p = 0.0247). In group B, 2 patients are alive with NED, 1 patient is alive with disease, and the remaining 12 patients have died a tumor-related death. Three cases of pneumothorax requiring intubation were observed.

Conclusions

RFA is less invasive than surgery and is an effective treatment option for curative and palliative therapy as an alternative to invasive salvage surgery for post-chemotherapeutic metastatic lung or liver lesions from GCT.
