Article Synopsis
  • - A study examined medical records of 298 patients who had renal transplants, revealing that 15.1% developed malignant tumors, with skin cancer being the most common type.
  • - The cumulative incidence of developing these tumors was 6.0% within 10 years and 17.9% within 20 years after the transplant.
  • - Risk factors identified included older age at transplantation and the use of certain medications like cyclosporine and rituximab, with rituximab showing a potential link to increased tumor development.

BACKGROUND Identifying characteristics of patients at high risk of poor adherence before transplantation would be advantageous. However, the optimal approach for characterizing such patients remains unknown. We aimed to evaluate the association between factors for hemodialysis nonadherence and post-transplant renal prognosis.

We report the clinical and pathological findings of a case of de novo minimal change disease (MCD) after ABO-incompatible living kidney transplantation. A 62-yr-old man with end-stage renal disease associated with type I diabetes received ABO-incompatible kidney transplantation from his 58-yr-old wife. Although allograft function was excellent immediately after surgery, massive proteinuria (35 g/d) appeared on post-transplantation day 5.

Matrix metalloproteinases (MMPs) are associated with cell invasion under various physiological and pathological conditions. Among MMPs, MMP-10 is reported to correlate with a high pT stage and progression in a variety of cancer types. However, the clinical and pathological significance of MMP-10 in human prostate cancer tissues remains unclear.

Various therapeutic modalities are available for treatment of bladder cancer, and their effectiveness and patient outcome often depend on cancer cell invasiveness. However, the mechanisms underlying the early steps of bladder cancer cell invasion remain unknown. This study aimed to clarify the relationships between S100A4 expression and bladder cancer invasion of surrounding muscles, prognosis and expression of matrix metalloproteinase (MMP)-14 in patients with organ-confined bladder cancer.

Purpose: X-linked inhibitor of apoptosis (XIAP) has high affinity and strong inhibitory activity on apoptosis-related caspase-3. The relationships between expression of XIAP and cleaved caspase-3, and response to neo-adjuvant hormonal therapy (NHT) remain elusive. The aim was to investigate whether NHT influences with XIAP expression in prostate cancer patients.

Objectives: Lymphangiogenesis is associated with tumor progression in various cancers and is regulated by vascular endothelial growth factors (VEGFs). However, little is known about the pathologic roles of lymphangiogenesis in renal cell carcinoma (RCC). We investigated the relationships between various clinicopathologic features and lymphangiogenesis, angiogenesis, and expression of VEGFs in RCC.

Objectives: Matrix metalloproteinase (MMP)-10 is associated with malignant aggressiveness in various cancers, but its importance has not been investigated in conventional renal cell carcinoma (CRCC). The purpose of this study was to determine the clinical significance and malignant potential of MMP-10 in human CRCC tissues.

Patients And Methods: Specimens were obtained from 103 CRCC patients who underwent radical surgery and were examined by immunohistochemistry for MMP-10 expression.

Purpose: The expression of matrix metalloproteinase-7 (MMP-7) correlates with the malignant potential of various tumors and patient survival. We investigated the clinical and prognostic significance of MMP-7 expression in cancer cells and endothelial cells in human renal cell carcinoma (RCC).

Experimental Design: We reviewed tissue samples of 156 patients with RCC who had undergone radical operation.
