[Treatment results of stage IA Hodgkin lymphoma: a report of 97 cases].
OBJECTIVE
The treatment strategies of Hodgkin's lymphoma (HL) are different according to clinical stage and risk factors, yet the optimal treatment strategy remains unclear. This study was to analyze the treatment results and prognostic factors of stage IA HL.


METHODS
According to prognosis, 97 patients with stage IA HL were divided into 3 groups: 7 (7.2%) in very favorable (VF) group, 72 (74.2%) in favorable (F) group, and 18 (18.6%) in unfavorable (UF) group. Short-term treatment outcome and long-term survival were analyzed. The prognosis was analyzed with Cox regression model.


RESULTS
Median follow-up time was 65 months. After radiotherapy or radiochemotherapy, 90 patients (92.8%) achieved complete remission (CR). The 5-and 10-year overall survival (OS) rates were 87.7% and 76.3%; the 5-and 10-year disease-free survival (DFS) rates were 79.4% and 74.5%. The 5-and 10-year OS rates were 100% and 100% in VF group, 88.9% and 88.4% in F group, 78.1% and 39.1% in UF group (P=0.292). The 5-and 10-year DFS rates were 100% and 87.2% in VF group, 86.3% and 71.8% in F group, 73.6% and 34.5% in UF group (P=0.032). Cox analysis showed that pathologic type (P=0.056) and tumor relapse (P=0.011) influenced OS, and the response to primary treatment (P=0.024) influenced DFS. The relapse rate was 18.6%û there was no significant difference between the patients received radiotherapy alone and those received radiochemotherapy (Chi(2)=0.072, P=0.788). The occurrence rate of secondary malignancies was 5.2%, including 2 cases of non-Hodgkin's lymphoma. All the 12 patients who died had received radiotherapy alone.


CONCLUSIONS
More than 90% of stage IA HL patients can achieve CR with radiotherapy alone or chemoradiotherapy. The long-term OS and DFS of the patients who received radiochemotherapy are better than those of the patients who received radiotherapy alone. The pathologic type, response to primary treatment and tumor relapse may be independent prognostic factors of stage IA HL.
