Abstract:
OBJECTIVETo analyze the outcome and prognosis of autologous hematopoietic stem cell transplantation (AHSCT) combined with high dose radiotherapy/chemotherapy in 22 patients with nasal NK/T cell lymphoma.
METHODSFrom July 1992 to December 2005, 22 patients with nasal NK/T cell lymphoma were diagnosed pathologically. Immunophenotyping was performed in 13 cases. The patients were classified by Ann Arbor staging system and international prognosis index (IPI). The patients received cycles of chemotherapy every other two weeks or combined with radiotherapy for remission induction, followed high dose radiotherapy/chemotherapy, combined with autologous peripheral blood stem cell transplantation (APBSCT), or autologous bone-marrow transplantation (ABMT). Patients were given complementary radiotherapy after transplantation if they did not have it before. Twelve patients of IPI 3 -4 received consolidation chemotherapy, and one of them received the second transplantation.
RESULTSThe median follow-up duration was 64 (12 - 168) months. The 5 and 8-year overall survivals (OS) were 79.3% and 64.1%, and disease free survivals (DFS) were 36.4% and 27.3%, respectively. The 5-year OS were as follows: for stage I - II and III - IV disease were 90.0% and 70.0% (P = 0. 041); for patients without and with B symptom were 100.0% and 70.7% (P = 0.045); and for IPI 1 - 2 and 3 - 4 were 100.0% and 60.0% (P = 0.035), respectively. Multivariate analysis by COX regression revealed that disease stage, B symptom and IPI were independent prognostic factors.
CONCLUSIONAHSCT combined with high dose radiotherapy/chemotherapy is an effective treatment for patients with poor prognosis nasal NK/T cell lymphoma.
