Intravesical recurrence after surgical management of urothelial carcinoma of the upper urinary tract.

Objectives: To elucidate clinicopathological risk factors for intravesical recurrence (IVR) in patients undergoing nephroureterectomy for upper urinary tract urothelial carcinoma (UUT-UC).

Methods: We identified a study population of 151 consecutive patients without previous or concurrent bladder cancer who underwent nephroureterectomy for UUT-UC. IVR was assessed in relation to tumor location, size, and multifocality, operation modality and time, stage, grade, lymphovascular invasion, regional lymph node metastasis, preoperative urinary cytology, and perioperative chemotherapy.

Effects of α1-Blockers for Lower Urinary Tract Symptoms and Sleep Disorders in Patients with Benign Prostatic Hyperplasia.

Objectives: We evaluated the association of lower urinary tract symptoms (LUTS) and sleep disorders (SD) in patients with benign prostatic hyperplasia (BPH). We also examined improvement of SD following the α1-blocker therapy for LUTS.

Methods: Sixty-eight male patients were enrolled in the study, consisting of 38 cases with LUTS and BPH (BPH group), and 30 men without significant LUTS or BPH (non-BPH group).

Metastasectomy for renal cell carcinoma as a strategy to obtain complete remission.

We report a case of 67-year-old Japanese woman with two types of metastasectomy for metachronous metastases of renal cell carcinoma (RCC). The initial nephrectomy for left RCC was performed in April 1977. The pathological diagnosis was clear cell carcinoma grade1-2, pT1b.

Tension-free vaginal mesh procedure for pelvic organ prolapse: a single-center experience of 310 cases with 1-year follow up.

Objective: To prospectively evaluate the efficacy of a tension-free vaginal mesh (TVM) procedure for pelvic organ prolapse (POP).

Methods: Between December 2005 and April 2008, 310 female patients (mean age 67.2 years, range 42-84) with POP underwent TVM procedures at our institute.

Neoadjuvant LHRH analog plus estramustine phosphate combined with three-dimensional conformal radiotherapy for intermediate- to high-risk prostate cancer: a randomized study.

Objective: The objective of this study is to assess the safety and efficacy of a treatment regimen comprising neoadjuvant conventional androgen deprivation therapy (ADT) plus estramustine phosphate (EMP) combined with three-dimensional conformal radiotherapy (3D-CRT) for patients with intermediate- to high-risk prostate cancer.

Methods: Thirty-nine patients with intermediate- to high-risk prostate cancer classified according to the NCCN practice guidelines recurrence risk group were randomly allocated into two groups: neoadjuvant LHRH agonist plus EMP for 6 months until completion of the 3D-CRT (EMP group, n = 20), or neoadjuvant LHRH agonist alone (LHRH group, n = 19). Both groups received 3D-CRT in daily fractions of 2 Gy for a total dose of 70 Gy.

How do symptoms have an impact on the prognosis of renal cell carcinoma?

Aim: Symptomatic renal cell carcinoma (RCC) is well known to have a characteristic behavior. We therefore evaluated the impact of systemic symptoms on the prognosis of RCC.

Methods: Patard's criteria were used to classify symptoms before operation into three groups defined as: S1 (incidental tumor), S2 (localized symptoms) and S3 (systemic symptoms).

Significant relationship of matrix metalloproteinase 9 with nuclear grade and prognostic impact of tissue inhibitor of metalloproteinase 2 for incidental clear cell renal cell carcinoma.

Objective: To examine the immunoreactivity of tumors for matrix metalloproteinases 2 and 9 (MMP-2, MMP-9), tissue inhibitors of metalloproteinases 1 and 2 (TIMP-1, TIMP-2), and membrane type MMP 1 (MT-MMP-1), to evaluate the optimum assessment of incidental renal cell carcinoma.

Methods: Tumor samples from 120 incidental clear cell renal cell carcinoma (ICRCC) patients without distant metastasis or invasion beyond Gerota's fascia were obtained by surgery. They were immunohistochemically stained for MMP-2, MMP-9, TIMP-1, TIMP-2, and MT-MMP-1.

Strong significant correlation between MMP-9 and systemic symptoms in patients with localized renal cell carcinoma.

Objectives: To identify a relationship between clinical symptoms and matrix metalloproteinase (MMP)-2 and MMP-9, tissue inhibitor of metalloproteinase (TIMP)-1 and TIMP-2, and membrane type MMP-1.

Methods: Tumor samples from 232 patients with renal cell carcinoma with no distant metastasis were immunohistochemically stained for MMP-2 and MMP-9, TIMP-1 and TIMP-2, and membrane type MMP-1. The immunoreactivity of these factors was analyzed by semiquantitative multivariate analysis for correlation with clinical symptoms.

Long-term outcome from a study on the prevention of postoperative recurrence in patients with renal cell carcinoma: could PBL be a predictor of postoperative recurrence in patients postoperatively treated with IFN-gamma?

This study examined the outcome of postoperative recurrence therapy on renal cell carcinoma (RCC) prevention involving treatment with single doses of interferon-gamma (IFN-gamma). From 1990-2000, 37 patients with no distant metastasis at the time they underwent a nephrectomy were enrolled in this investigation. Subcutaneous IFN-gamma was administered once a week.

The impact of angiogenesis on the prognosis of advanced renal cell carcinomas.

We studied the relationship between angiogenic factors and clinical responses in advanced renal cell carcinomas (RCCs) and evaluated the angiogenic factors to clarify the potential impact of these factors on the cancer-specific survival. From January 1990 to December 2000, 148 patients underwent a nephrectomy for RCCs at our institution. Of the 32 patients who had distant metastasis, 17 met the histopathologic analysis requirements for an immuno-histochemical investigation.
