A Case of Malignant Pheochromocytoma Detected during Fertility Treatment.

We report a case of malignant pheochromocytoma in a 35-year-old Japanese woman during fertility treatment, successfully treated with surgical excision. The patient recovered without any postoperative problems, and plasma catecholamine levels normalized. At present, 18 months after the operation, there are no signs of relapse.

Extravasation during bladder cancer metastasis requires cortactin‑mediated invadopodia formation.

Invasive cancer cells form the filamentous actin‑based membrane protrusions known as invadopodia. Invadopodia are thought to play a critical role in cancer cell invasion and metastasis due to their ability to degrade the extracellular matrix. The present study assessed whether invadopodia formation is essential in extravasation of circulating bladder cancer cells and lung metastasis.

A case of metastatic cancer with markedly elevated PSA level that was not detected by repeat prostate biopsy.

Background: Prostate-specific antigen (PSA) is a widely used specific tumor marker for prostate cancer. We experienced a case of metastatic prostate cancer that was difficult to detect by repeat prostate biopsy despite a markedly elevated serum PSA level.

Case Presentation: A 64-year-old man was referred to our hospital with lumbar back pain and an elevated serum PSA level of 2036 ng/mL.

Presurgical therapy with axitinib for advanced renal cell carcinoma: a case report.

Background: Targeted therapy with tyrosine kinase inhibitors has been shown to reduce tumor volumes and prolong the survival of patients with metastatic renal cell carcinoma. Tyrosine kinase inhibitors, particularly sunitinib, have recently been used in neoadjuvant and presurgical settings. Axitinib is a promising second-line therapy option for advanced or metastatic renal cell carcinoma.

Prognosis of elderly Japanese patients aged ≥80 years undergoing hemodialysis.

Although the number of elderly patients requiring dialysis has increased, data regarding the prognosis of elderly patients undergoing hemodialysis are limited. In the present study, prognosis in Japanese hemodialysis patients aged ≥80 years was evaluated. From January 1988 to July 2013, 1144 consecutive patients with end-stage renal disease required renal replacement therapy at our institution; of these, 141 were aged ≥80 years.

Histopathological diagnosis was thyroid carcinoid.

In vivo selection of high-metastatic subline of bladder cancer cell and its characterization.

The majority of deaths associated with solid tumors are caused by tumor metastasis. To prevent metastasis, it is vital to understand its detailed process. In hematogenous metastasis of bladder cancer, some cancer cells disseminating into blood circulation extravasate into the lung tissues to form metastases.

Impact of body mass index on clinicopathological outcome and biochemical recurrence after radical prostatectomy.

Background: Accumulating evidence suggests that obesity is associated with tumor progression in prostate cancer (PCa) patients after radical prostatectomy (RP). We conducted a retrospective multicenter study to determine the effect of body mass index (BMI) on the clinicopathological characteristics and biochemical recurrence of PCa in Japanese men who underwent RP.

Methods: The medical records of 1257 men with PCa treated by RP without neoadjuvant therapy at four medical institutes between 2001 and 2009 were retrospectively reviewed.

Is pelvic lymph node dissection required at radical prostatectomy for low-risk prostate cancer?

Objectives: To determine the necessity of pelvic lymph node dissection for low-risk prostate cancer, we analyzed the incidence of lymph node invasion and the therapeutic value of pelvic lymph node dissection in low-risk prostate cancer patients.

Methods: Medical records for 1268 patients undergoing open radical prostatectomy between January 2000 and December 2009 who had not undergone neoadjuvant therapy were retrospectively reviewed. Patients with low-risk disease (n = 222; prostate-specific antigen <10 ng/mL, biopsy Gleason score ≤6, clinical T1c or T2a) were classified according to whether they underwent pelvic lymph node dissection (pelvic lymph node dissection group, n = 147) or did not (no pelvic lymph node dissection group, n = 75).

Pathological and biochemical outcomes after radical prostatectomy in men with low-risk prostate cancer meeting the Prostate Cancer International: Active Surveillance criteria.

Unlabelled: WHAT'S KNOWN ON THE SUBJECT? AND WHAT DOES THE STUDY ADD?: Active surveillance has been widely accepted as a treatment tool for low-risk prostate cancer, and use of the Prostate Cancer Research International: Active Surveillance (PRIAS) criteria can select smaller and less aggressive tumours in low-risk disease. The study shows the pathological outcomes of radical prostatectomy for patients with low-risk disease who met the PRIAS criteria. It found that ~20% had unfavourable pathological features and only 30% satisfied insignificant cancer criteria with pT2 stage, a Gleason score ≤6 and tumour volume <2.

Blood group antigen-targeting peptide suppresses anti-blood group antibody binding to antigen in renal glomerular capillaries after ABO-incompatible blood reperfusion.

Background: Antibody-mediated rejection after ABO-incompatible kidney transplantation (ABO-I KTx) is a major barrier to transplantation success. The advent of immunosuppressive therapy has markedly improved graft survival in ABO-I KTx. However, compared with normal KTx, clinical conditions during ABO-I KTx are difficult to control because of overimmunosuppression.
