Compared with the West, the overall incidence of lymphoid neoplasms is lower, and the subtype distribution is distinct in Asia. To comprehensively investigate the subtype distribution with the age and sex factors, and temporal changes of subtype proportions, we re-assessed all patients with lymphoid neoplasms diagnosed at a large oncology service in the(More)
OBJECTIVE To investigate the prognostic significance of tumor morphology in relation to progression and survival in patients with primary T1G3 bladder cancer (BC) METHODS: After review of pathology, 194 patients who were diagnosed with primary T1G3 BC after clinically complete transurethral resection between 1989 and 2005 were seen. Of these patients, 144(More)
One of the major challenges in bladder cancer management is in distinguishing aggressive from indolent tumors with similar clinicopathological factors, especially in cases of high-grade T1 stage tumors. To define a set of prognostic factors that can be easily assessed in clinical practice with a high cost-effectiveness, the expressions of 11 proteins were(More)
BACKGROUND Assessment of tumor cell proliferation based on Ki-67 expression yielded conflicting prognostic predictions of patients with diffuse large B-cell lymphoma (DLBCL). The introduction of rituximab to the DLBCL treatment regime has led to alterations in the significance of previous prognostic factors. METHODS We analyzed Ki-67 expression and its(More)
High-grade non-muscle-invasive bladder cancer (Non-MIBC) has a high risk of stage progression to muscle-invasive bladder cancer (MIBC) and could be managed either conservatively by transurethral resection of bladder tumor (TURBT) or more aggressively by radical cystectomy. The selection of patients who may benefit from early radical intervention is a(More)
BACKGROUND Different cell types in the kidney, including those in tubules, glomeruli, and interstitium, have been proposed as candidate adult renal stem cells, raising controversy about the very existence of such cells. In this study, we sought to clarify the location and nature of adult renal stem cells and to address their reparative role in native kidney(More)
Histologic distinction between complete hydatidiform moles and nonmolar abortuses in early pregnancy is often extremely difficult. This study details the chronologic changes that occur in normal placenta, especially in the villous stroma during gestational weeks 4 to 12 and compares the findings in 63 normal placentas and 73 early complete moles. Over time,(More)
AIM Sphingosine-1-phosphate receptor 1 (S1PR1) promotes tumour cell survival, invasion, anti-apoptosis, metastasis and radio/chemo-resistance in various cancers. However, the expression pattern and prognostic implications of S1PR1 in urothelial carcinoma remain unclear and thus were addressed here. METHODS Tissue microarrays composed of 395 initially(More)
Reported herein are seven cases of a histologically distinct oncocytic papillary renal cell carcinoma (OPRCC) with an inverted nuclear pattern. To define its prognostic significance, the clinicopathological features of OPRCC were compared to those of types 1 and 2 PRCC. The median age of the seven patients was 67 years. Grossly, tumors were(More)
