[Combined-modality therapy for 150 cases of early-stage Hodgkin's lymphoma].

Objective: To compare the efficacy of chemotherapy alone, radiotherapy alone and combined-modality therapy in the treatment for early-stage Hodgkin's lymphoma (HL).

Methods: From 1999 to 2002, totally 150 patients with stage I or II HL were treated in our hospital. They were stratified into several groups based on initial treatment strategy: chemotherapy alone (CT group, n = 22), radiotherapy alone (RT group, n = 18), combined-modality therapy (CMT group, n = 109) and surgical resection (SR group, n = 1).

Primary early-stage intestinal and colonic non-Hodgkin's lymphoma: clinical features, management, and outcome of 37 patients.

Aim: To analyze the clinical features, management, and outcome of treatment of patients with primary intestinal and colonic non-Hodgkin's lymphoma (PICL).

Methods: A retrospective study was performed in 37 patients with early-stage PICL who were treated in our hospital from 1958 to 1998. Their clinical features, management, and outcome were assessed.

[Clinical features, treatment and prognosis of 136 patients with primary non-Hodgkin's lymphoma of the nasopharynx].

Objective: To investigate the clinical characteristics, international prognostic index and treatment of primary non-Hodgkin's lymphoma (NHL) of the nasopharynx.

Methods: From January 1983 to December 1997, 136 patients with previously untreated NHL of the nasopharynx were retrospectively reviewed. All patients were confirmed pathologically and classified by Working Formulation system.

[Primary central nervous system lymphoma: a report of 28 patients].

Objective: To evaluate the clinical characteristics, reasonable mode of treatment and prognostic factors in patients with primary central nervous system lymphoma (PCNSL).

Methods: Twenty-eight patients with PCNSL treated from 1989 to 2002 were retrospectively reviewed. The clinical characteristics, results of treatment and prognostic factors were analyzed by SPSS10.

[Prognostic factors in patients with primary non-Hodgkin's lymphoma of the tonsil].

Objective: To investigate the prognostic value of the size of primary tumor (T staging) and international prognostic index (IPI) for patients with non-Hodgkin's lymphoma (NHL) of the tonsil, and to recommend the treatment strategy for early stage patients.

Methods: 306 patients with untreated NHL of the tonsil were reviewed. According to Ann Arbor staging classification, 35 patients had stage I, 178 stage II, 49 stage III and 44 stage IV disease.
