  Objective

The objective of this study was to evaluate the efficacy and toxicity of docetaxel in combination with prednisolone in Japanese patients with hormone refractory prostate cancer.

Methods

Twenty patients with hormone refractory prostate cancer (HRPC) were administered a treatment regimen consisting of docetaxel 75 mg/m2 once every 3 or 4 weeks and prednisolone 5 mg twice daily at our institution between 2006 and 2008.

Results

The patients received a median of 5.5 cycles of treatment (range, 2–12 cycles). Nine of the 20 patients (45%) had a ≥50% decrease in serum prostate-specific antigen (PSA). The median duration of response was 4 months (range, 1–11 months). The number of cycles performed, the presence of bone metastasis and the extent of disease had statistically significant associations with the response. Three patients had a transient PSA rise among the patients who ultimately had a response. Grade 3/4 leukopenia and neutropenia occurred in 80.0% and 85.0% of the patients, respectively. Interstitial pneumonia occurred in only one patient; however, the patient recovered. Finally, no treatment-related deaths were seen during the observation period.

Conclusions

The combination of docetaxel 75 mg/m2 every 3 weeks and prednisolone 10 mg daily was effective and well tolerated in Japanese patients with HRPC. The results of this study suggest that a decision concerning discontinuation of this treatment should be carefully considered because a transient PSA rise was observed. Although interstitial pneumonia was rare, the potential risk of its development should be taken into consideration.

  Objective

The aim of this study was to determine the incidence and risk factors of postoperative inguinal hernia and to investigate whether the difference of approach could induce postoperative inguinal hernia after laparoscopic radical prostatectomy.

Methods

We reviewed 493 consecutive patients who underwent laparoscopic radical prostatectomy from November 2000 to November 2007, and evaluated various preoperative parameters, specifically age, prostate-specific antigen (ng/ml), body mass index (kg/m2), prostate volume (ml), previous major abdominal surgery, previous appendectomy, previous inguinal hernia repair and laparoscopic approach as risk factors for postoperative inguinal hernia.

Results

Inguinal hernia occurred in 4 (4.9%) of the 81 patients in the transperitoneal approach group, and in 37 (9.0%) of the 412 patients in the extraperitoneal approach group. The overall incidence of inguinal hernia was 8.3% (41 of 493 patients). The median inguinal hernia-free survival time was 35 months and 6 months in the transperitoneal approach and extraperitoneal approach groups, respectively. Inguinal hernia developed within 2 years after surgery in 2 (50%) of 4 patients in the transperitoneal approach group, in 34 (91.9%) of 37 patients in the extraperitoneal approach group, for a total of 36 (87.8%) of 41 patients overall. Multivariate analysis showed that the extraperitoneal approach was a significant risk factor (P = 0.043) for inguinal hernia.

Conclusions

Inguinal hernia is a frequent complication after laparoscopic radical prostatectomy, and the incidence of inguinal hernia is greater with the extraperitoneal approach than with the transperitoneal approach.

Adrenocortical cancer (ACC) is a rare and aggressive endocrine tumor. The patient presented with a large retroperitoneum tumor and lung metastases. Removal of the adrenocortical tumor with part of the transverse colon and tail of the pancreas, spleen and kidney was successfully performed following chemotherapy. Levels of serum neuron-specific enolase (NSE) were found to be markedly high before surgery and may be clinically useful markers for monitoring tumor status during management. Immunohistochemical studies showed that the cancer cells were positive for NSE and overexpression of p53. We identified a novel germ line variant of the 177 mutant (Pro to Arg; P177R) of p53 by genomic sequencing. The genetic and biochemical data presented in this case confirm the importance of screening for p53 status in ACC with inherited cancer syndrome.
