| Abstract: |
| Objective The study aimed to explore the clinical efficacy of P-Gemox regimen sandwich radiotherapy,
P-Gemox regimen sequential radiotherapy, and radiotherapy alone in early-stage extranodal natural killer/
T-cell lymphoma (ENKTL).
Methods In total, 124 patients with early-stage ENKTL, from June 2009 to January 2016, were
retrospectively analyzed to compare the clinical efficacy of the three regimens.
Results A total of 46 patients were treated with P-Gemox regimen sandwich radiotherapy, with complete
remission (CR) of 91.3%, objective response rate (ORR) of 97.8%, 2-year progression-free survival
(PFS) of 76.1%, and 2-year overall survival (OS) of 80.4%. Then, 37 patients received P-Gemox regimen
sequential radiotherapy, with CR of 86.5%, ORR of 94.6%, 2-year PFS of 75.7%, and 2-year OS of 81.1%.
Finally, 41 patients received radiotherapy alone, with CR of 61.0%, ORR of 80.5%, 2-year PFS of 51.2%,
and 2-year OS of 65.9%. When the two groups were compared, significant differences in CR, PFS, and
OS were observed among the sandwich radiotherapy, sequential radiotherapy, and radiotherapy alone
groups (P < 0.05), respectively. However, no significant difference in CR, ORR, PFS, and OS was observed
between the sandwich radiotherapy and sequential radiotherapy groups (P > 0.05). Multivariate analysis
revealed that Eastern Cooperative Oncology Group (ECOG), serum lactate dehydrogenase (LDH), plateletto-lymphocyte ratio (PLR), local tumor invasion, and treatment modalities were independent prognostic
factors for PFS (P < 0.05). ECOG, LDH, PLR, local tumor invasion, underlying disease, and treatment
modalities were independent prognostic factors for OS (P < 0.05).
Conclusion P-Gemox regimen combination radiotherapy for patients with early-stage ENKTL was better
than the radiotherapy alone. |
