Abstract

BACKGROUND AND AIM:

About 20-25% of the testicular germ cell tumors (TGCT) are relapsed or refractory after first line therapy and optimal treatment for this group is poorly defined. We aimed to analyze the efficacy and safety of autologous stem cell transplantation (ASCT) in this patient group.Material and.

METHODS:

19 patients with 28 ASCT were retrospectively analyzed. All the patients were treated with BEP (Bleomycin, etoposide, cisplatin) as first line therapy and TIP(paclitexalifosfamide, cisplatin) was given as salvage chemotherapy. Stem cell collection was performed with TIP and granulocyte stimulating factor. ASCT was performed with carboplatin(700mg/m2) and etoposite(750mg /m 2). The results were provided as median(min-max). P<0.05 was accepted as statistical significant level.

RESULTS:

After ASCT, complete(CR) and partial remission (PR) rates were 47.3% and 31 .5% respectively. The median overall survival(OS) and progression free survival (PFS) were 18(0-37.4 months) and 7(0-15months) months respectively. Estimated 2-year OS was 47.4% and PFS was 35.3%. Grade 3/4 toxicities including diarrhea, mucositis, and toxic hepatitis were observed in 5 patients. Only one patient died due to complication of transplantation.

CONCLUSION:

Although the number of the patients in this study is limited, ASCT seems to be a safe and effective treatment modality in relapsed refractory non-seminomatousTGCT with an acceptable OS, PFS and mortality rates.
