To clarify the clinicopathologic findings of idiopathic multicentric Castleman disease among Japanese, 28 cases were studied. Two variants were delineated by the clinicopathologic findings (1) idiopathic plasmacytic lymphadenopathy with polyclonal hyperimmunoglobulinemia (n = 18) and (2) nonidiopathic plasmacytic lymphadenopathy type (n= 10). Clinicopathologically, idiopathic plasmacytic lymphadenopathy was defined by the prominent polyclonal hyperimmunoglobulinemia, normal germinal centers, and sheet-like infiltration of plasma cells in the interfollicular area of the lymph node. Histologically, the nonidiopathic plasmacytic lymphadenopathy type was characterized by hyaline-vascular germinal centers of the lymph node lesion. In comparison with idiopathic plasmacytic lymphadenopathy, patients with nonidiopathic plasmacytic lymphadenopathy showed infrequent prominent polyclonal hyperimmunoglobulinemia and frequent association with autoimmune disease. However, there was no difference in the overall 5-year survival between the 2 subtypes. Compared with idiopathic multicentric Castleman disease in Western countries, the chronic course of the disease of idiopathic multicentric Castleman disease in Japan appears to be related to negativity for human herpesvirus 8 infection.

Despite the outstanding results generally obtained with imatinib mesylate (IM) in the treatment of chronic myeloid leukemia (CML), some patients show a poor molecular response. To evaluate the relationship between steady-state trough plasma IM concentration (IM-C(min)) and clinical response in CML patients, we integrated data from six independent Japanese studies. Among 254 CML patients, the mean IM-C(min) was 1,010.5 ng/ml. Importantly, IM-C(min) was significantly higher in patients who achieved a major molecular response (MMR) than in those who did not (P = 0.002). Multivariate analysis showed that an MMR was associated with both age (odds ratio (OR) = 0.97 (0.958-0.995); P = 0.0153) and with IM-C(min) (OR = 1.0008 (1.0003-1.0015); P = 0.0044). Given that patients with IM-C(min) values >1,002 ng/ml had a higher probability of achieving an MMR in our large cohort (P = 0.0120), the data suggest that monitoring of IM levels in plasma may improve the efficacy of IM therapy for CML patients.

The purpose of this study is to investigate the side effect in patients who survived for more than 5 years after initial treatment for invasive cervical cancer. Between January 1984 and December 1997, 341 patients underwent primary treatment for invasive cervical cancer. One hundred nine patients who underwent medical examinations at 5 years after primary treatment were reviewed. The patients were divided into three groups: radical surgery alone (group A), radiotherapy alone (group B), and radical surgery with postoperative radiotherapy (group C). Dysuria was seen in 8%, and positive catheterized urine culture was noted in about 20% of groups A and C. Hydronephrosis was seen in 2% and 9% of groups A and B, respectively. Colitis or ulcer detected by proctosigmoidoscopy was noted in 15%, 50%, and 43% of groups A, B, and C, respectively, frequently observed in radiotherapy group (P= 0.0029). Lymphocyst was still present in 6% of group A, and leg edema was noted in 14%, 6%, and 15% of groups A, B, and C, respectively. Long-standing abnormal findings including urinary and bowel complications were presented in this study. Periodic physical examination after treatment should be performed because complications existed over a long time.

It is important to recognize the clinical features and available treatments for cervical varix.
