Combined-modality therapy for 150 cases of early-stage Hodgkin's lymphoma / 中华肿瘤杂志

<p><b>OBJECTIVE</b>To compare the efficacy of chemotherapy alone, radiotherapy alone and combined-modality therapy in the treatment for early-stage Hodgkin's lymphoma (HL).</p><p><b>METHODS</b>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). Chemotherapy regimens were mainly ABVD (adriamycin, bleomycin, vinblastine and dacarbazine) and MOPP (mechlorethamine, vincristine, procarbazine and prednisone). Radiotherapy modes included involved field radiotherapy (IFRT), extended field radiotherapy (EFRT) and sub-total nodal irradiation (STNI).</p><p><b>RESULTS</b>The pathological types included nodular sclerosis (NS, n = 84), mixed-cellularity (MC, n = 39), lymphocyte-predominant (LP, n = 23), lymphocyte-depleted (LD, n = 3) and nodular lymphocyte predominant Hodgkin's disease (NLPHD, n = 1). Of those, 72 were evaluble in terms of prognostic factors. No poor prognostic factor was found in 36.1% or 29.2% of the patients according to EORTC or GHSG criteria, respectively. There were 33 patients with complete response (CR), 109 with partial response (PR), 5 with stable disease (SD) and 3 with progressive disease (PD) after initial therapy. The median follow-up period was 71.5 months. The overall 7-yr survival rate was 89.3%, and treatment failure rate at 6 years was 18.8%. The response rate of CMT group was superior to that of CT group, and the patients with nodular sclerosis or mixed-cellularity type had significantly lower risk of treatment failure (P = 0.009 and 0.019, respectively). The multivariate analysis revealed that the treatment strategies affected the prognosis significantly. The risk of failure of chemotherapy alone was 2.52 times higher than that of combined-modality therapy (P = 0.004). No predictive factor affecting OS was identified by either univariate or multivariate analysis. The patients in CMT group suffered more adverse effects than those in either CT or RT groups, which mainly consisted of leucopenia, alopecia and gastrointestinal symptoms.</p><p><b>CONCLUSION</b>Combined-modality therapy is more effective than chemotherapy alone or radiotherapy alone in the treatment for early stage Hodgkin's lymphoma. Though its acute adverse effects are more severe than that of chemotherapy or radiotherapy alone, it may reduce the risk of treatment failure.</p>

Clinical features, treatment and prognosis of 136 patients with primary non-Hodgkin's lymphoma of the nasopharynx / 中华肿瘤杂志

<p><b>OBJECTIVE</b>To investigate the clinical characteristics, international prognostic index and treatment of primary non-Hodgkin's lymphoma (NHL) of the nasopharynx.</p><p><b>METHODS</b>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. There were 18 patients with high-grade, 77 intermediate, 2 low-grade and 39 unclassifiable lymphoma. According to Ann Arbor classification, 25 patients had stage I, 91 stage II, 12 stage III and 8 stage IV lesions. Primary therapy was radiotherapy alone in 13 patients and radiotherapy combined with chemotherapy in 12 patients with stage I disease. In 88 patients with stage II, radiotherapy alone was given to 31 patients, and a combination of radiotherapy and chemotherapy to 57 patients. Chemotherapy was primary treatment for advanced stage III/IV diseases.</p><p><b>RESULTS</b>The overall survival rate (OS), cancer specific survival rate (CSS) and disease-free survival rate (DFS) at 5 and 10 years for all patients were 56.2%, 61.2%, 51.1% and 48.3%, 58.0%, 46.5%, respectively. As for international prognostic index (IPI), the 5-year CSS was 70.9% for 0 risk factor, 44.9% for 1 risk factor, 30.0% for 2 or 3 risk factors, respectively (P = 0.004). For stage I patients, the 5-year CSS was 83.1% for RT alone and 82.2% for combined modality therapy, respectively (P = 0.779). For patients with stage II, the 5-year CSS was 46.0% for radiotherapy alone and 70.9% for combined modality therapy. There was significant difference between them (P = 0.04). Multivariate analysis by Cox regression showed that Ann Arbor stage, B symptom and IPI were independent prognostic factors.</p><p><b>CONCLUSION</b>International prognostic index is an important prognostic factor for Non-Hodgkin's lymphoma of the nasopharynx and the combined modality therapy may be optimal for the stage II patients.</p>

Primary central nervous system lymphoma: a report of 28 patients / 中华肿瘤杂志

<p><b>OBJECTIVE</b>To evaluate the clinical characteristics, reasonable mode of treatment and prognostic factors in patients with primary central nervous system lymphoma (PCNSL).</p><p><b>METHODS</b>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 SPSS10.0 statistic software.</p><p><b>RESULTS</b>Of 28 patients, 18 men and 10 women with a median age of 52 years. The median survival time was 2 years (range 6 months-6 years). The 5-year survival rate was 21.4%. Nineteen patients had single-locus lesion and 9 multi-locus lesion, 78.6% of the patients were diagnosed as having B-cell origin, its main type being diffuse large cell lymphoma. According to international working formulation (WF), moderate-grade of histopathology was observed in 57.7% (15/28). Cox regression analysis revealed that single- or multi-locus lesion was only independent prognostic factor (P = 0.0417). Combined chemotherapy showed significant efficacy for those patients who had lesion of B-cell origin, high grade or multi-locus lesion, and the efficacy of irregular chemotherapy was better than that of regular chemotherapy.</p><p><b>CONCLUSION</b>Primary central nervous system lymphoma has a special prognostic factor. Chemotherapy plays a very important role in comprehensive treatment, irregular chemotherapy should be adopted as a regular treatment.</p>
