摘要
目的回顾分析原发性骨淋巴瘤(PBL)患者的疗效和预后因素。方法1994—2009年间本中心收治的PBL患者31例,均经病理证实为非霍奇金淋巴瘤,其中ⅠE、ⅡE、ⅣE期分别为22、4、5例。全组单纯手术1例、单纯放疗1例、单纯化疗2例、术后化疗4例、放化疗23例,放疗剂量中位数字为50Gy。结果随访时间中位数45.2个月。随访率为83.9%。随访满10年者9例。全组治疗后5、10年总生存率分别为92%、92%,无进展生存率分别为79%、70%。非联合放化疗组的完全缓解率为50%、进展或复发为2/8、复发时间中位数为6.8个月,联合放化疗组相应为65%、13%、39.1个月。单因素分析显示年龄≤50岁(χ^2=5.32,P=0.021)及美国东部肿瘤协作组(ECOG)体力状况(PS)评分0—1分(χ^2=5.48,P=0.019)为生存预后因素,国际预后指数评分≤1分(χ^2=7.81,P=0.005)及ECOGPS评分0—1分(χ^2=18.70,P=0.000)为无进展生存预后因素。结论PBL患者预后良好,放化疗应作为首选治疗方法,放疗剂量≥40Gy较安全可行。年轻及一般状况较好患者预后更好。
Objective To retrospectively analyze the treatment results and prognostic factors in patients with primary bone lymphomas (PBL). Methods Thirty-one patients with PBL treated between April 1994 and May 2009 at Sun Yat-sen University Cancer Center were analyzed. All patients were diagnosed by pathology. Twenty-two patients had stage ⅠE, 4 patients had stage ⅡE and 5 patients had stage ⅣE diseases. One patient was treated with surgical resection alone, 1 patient with radiotherapy (RT) alone, 2 patients with chemotherapy (CT) alone and 4 patients with resection followed by chemotherapy. The remaining 23 patients received CT combined with RT. The median radiation dose was 50 Gy. Results The median follow-up time was 45.2 months. The follow-up rate was 83.9%. Nine patients had a follow-up time of 10 years. The 5-year and 10-year overall survival rates were 92% and 92%, respectively. The 5-year and 10-year disease-free survival rates were 79% and 70%, respectively. In the group who received non- combined chemoradiotherapy, the complete response rate was 50%, the incidence of progression or recurrence was 2/8 and the median recurrence time was 6. 8 months. In the group who received combined chemoradiotherapy, the complete response rate was 65% , the incidence of progression or recurrence was 13% and the median recurrence time was 39. 1 months. In univariate analyses, favorable prognostic factors for survival included age ≤ 50 years ( χ^2= 5.32, P = 0. 021 ) and ECOG PS score 0 - 1 ( χ^2= 5.48, P = 0. 019). Favorable prognostic factors for DFS included IPI score ≤〈 1 (χ^2= 7. 81, P = 0. 005 ) and ECOG PS score 0 - 1 ( χ^2=18.70,P = 0. 000). Conclusions Treatment results of patients with PBL can be generally well. CT combined with RT appears to be the treatment of choice. RT dose ≥40 Gy is safe and feasible. Younger age and better performance status are associated with a better outcome.
