PURPOSE To analyze the results of radiotherapy (RT) for malignant lymphoma of the orbit and to evaluate them compared with the World Health Organization (WHO) classification published in 2001. METHODS AND MATERIALS The data from 29 patients with malignant lymphoma of the orbit treated with RT at Gunma University Hospital between 1978 and 2001 were(More)
OBJECTIVE We examined retrospectively the MR imaging findings in eight patients with mucinous carcinoma of the breast to better describe the imaging characteristics of this disease. CONCLUSION The MR imaging findings in mucinous carcinomas include dynamic curves of the gradually enhancing type and a very high signal intensity on T2-weighted images(More)
We conducted clinicopathologic and immunohistochemical analyses of the prevalence of Epstein-Barr virus (EBV) among 24 patients with malignant lymphoma complicating systemic rheumatic diseases. (SRD) These 24 patients included 17 with rheumatoid arthritis (RA), 3 with systemic lupus erythematosus (SLE), 2 with systemic sclerosis (SS), and 2 with(More)
To clarify the clinical presentation and outcome of nodal marginal zone B-cell lymphoma (NMZBL), 65 Japanese patients with this disease were studied and compared with the published literature from western countries. The clinical findings of our 65 cases were similar to those of their cases in some aspects: (1) 58% of the patients were > 60 years old (median(More)
BACKGROUND The previous trials of radiotherapy conducted for primary central nervous system lymphoma (PCNSL) have not been successful. Therefore, we have investigated the clinical outcomes and the role of radiation therapy in the treatment of PCNSL. METHODS Thirty-three consecutive patients with PCNSL treated with cranial radiotherapy (30-40 Gy whole(More)
OBJECTIVE The aim of this study is to evaluate retrospectively the role of radiotherapy for thymic carcinoma. METHODS Between 1973 and 1998, 14 patients with thymic carcinoma were treated at Gunma Prefectural Cancer Center. Two patients who had hematogenous metastasis were excluded from this study, therefore 12 patients were analyzed. The Masaoka staging(More)
CHOP (cyclophosphamide, doxorubicin, vincristine and prednisone) followed by radiotherapy is regarded as standard care for localized aggressive lymphoma; however, prospective confirmation of its applicability to localized primary gastric lymphoma is inadequate, and most patients in Japan have been initially treated with gastrectomy. We conducted a(More)
To clarify the clinicopathological findings of primary salivary gland lymphoma as defined by the World Health Organization (WHO) classification, 30 Japanese patients with this disease were studied. The male to female ratio was 1:1.7 and median patient age was 57 years. The parotid gland (n = 22) was involved most frequently, followed by the submandibular(More)
UNLABELLED The aim of this study was to examine the interobserver variance in delineating the contour of unresectable pancreatic cancer for chemoradiotherapy. PATIENTS AND METHODS CT images of two cases of unresectable pancreatic tumors (head and body cancer) were sent to eight radiation therapy facilities in a CD-ROM. Gross tumor volume (GTV) and(More)
PURPOSE To evaluate the reliability and validity of the Japanese translation of Quality of Life Radiation Therapy Instrument (QOL-RTI) and the head and neck module (H&N) for Japanese patients being treated with radiotherapy for head and neck malignancies. MATERIALS & METHODS The QOL-RTI/H&N was translated into Japanese by a preliminary QOL research(More)
