Abstract:
Objective To analyze clinical features and treatment results of primary non-Hodgkin lymphoma of bone (PLB) and further to investigate the rational treatment. Methods Clinical data of 26 patients with PLB were analyzed. Twenty-three (88.5 %) patients received radiotherapy in combination with chemotherapy, three received chemotherapy alone, and three patients also received surgical resection. Results The pathological types of lymphoma in the patients were diffused large B-cell iymphoma (DLBCL) in 15 patients (57.7 %), small B-cell lymphoma in 1 patient(3.8 %), B-cell lymphoma with unclassified subtypes in 4 patients (15.5 %), T-cell lymphoma in 5 patients (19.3 %,among which anaplastic large cell lymphoma in 3 patients), and unclassified lymphoma in one patient (3.8 %). Of the 26 cases of PLB, 15 were at stage Ⅰ, 3 at stage Ⅱ, 3 at stage Ⅲ and 5 at stage Ⅵ. The 3- and 5-year overall survival rates were 59.16 % and 31.37 %respectively. In the eleven patients who died of lymphoma, three had Iocol-regional relapse, and nine had systemically involved lymphoma. The radiation-induced bone fracture had not been observed after local radiotherapy with median dose of 50 Gy. Conclusion Pelvis maybe a common primary site of PLB, and DLBCL type are the most observed histological subtype. The optimal treatment for PLB is radiotherapy combined with chemotherapy. Local regional radiotherapy with median dose of 50 Gy can be safe and feasible.
