    Notes: A right nephrectomy was performed on a 51 year-old female with a tumor surrounding the right kidney since the possibility of malignant lymphoma could not be excluded based on radiography or a needle biopsy. An immunohistological examination of the surgically-resected specimen confirmed a diagnosis of pseudolymphoma. A pseudolymphoma involving the urinary tract is rare, and this is only the second reported case of pseudolymphoma in the perirenal space.

    Notes: We report a case of malignant phyllodes tumor of the prostate which is the eleventh reported case in the world. Phyllodes tumor of the prostate is extremely rare and histologically resembles mammary phyllodes tumor. Phyllodes tumor of the prostate is classified into benign, borderline and malignant, but health professionals should carefully follow up the borderline cases in case they take a malignant clinical course. This case was the first to be treated by pre- and postoperative radiation therapy. Although the patient had a slight response to radiation therapy, he eventually developed metastasis. Because malignant phyllodes tumor of the prostate is a very aggressive tumor, people with the condition should undergo systemic chemotherapy as adjuvant therapy.

    Efficacy of transurethral needle ablation of the prostate for the treatment of benign prostatic hyperplasia (1999)

    Notes: Background: We evaluated the efficacy and safety of transurethral needle ablation (TUNATM) of the prostate for treatment of symptomatic benign prostatic hyperplasia (BPH) as one institute participating in a Japanese clinical trial. Methods: Thirty-three patients with symptomatic BPH were treated with the TUNATM procedure in our institute. The international prostate symptom score (IPSS), quality of life (QOL) score, residual urine volume (RV), prostate volume (PV) and peak urinary flow rates (Qmax) were measured and complications were assessed. Results: We followed and evaluated 30 of the 33 cases. At 12 months there were significant improvements in the IPSS (20.7 to 11.2, P 〈 0.0001), QOL score (4.9 to 2.1, P 〈 0.0001), RV (46.6 to 22.6 mL, P 〈 0.01), PV (37.8 to 30.0 mL3, P 〈 0.002) and Qmax (8.00 to 11.0 mL/s, P 〈 0.002). There were no serious complications. Conclusion: This trial shows that the TUNATM procedure is a safe and efficacious treatment for symptomatic BPH.

    M1 prostate cancer with a serum level of prostate-specific antigen less than 10 ng/mL (2001)

    Notes: Abstract Background: M1 prostate cancer, which is invasive, is usually associated with a serum level of prostate-specific antigen (PSA) greater than 10 ng/mL, but cases are occurring where the serum PSA level is less than this. The present study investigated the clinical and pathologic characteristics of these cases of M1 prostate cancer.〈section xml:id="abs1-1"〉〈title type="main"〉Methods:Between April 1989 and March 1998, 167 cases of M1 prostate cancer were diagnosed by transrectal needle biopsy and eight of these with a serum PSA level less than 10 ng/mL were investigated. The patients' ages ranged from 57 to 79 years (median, 73) and the serum PSA levels ranged from less than 4.0 to 9.8 ng/mL. In all cases except one, the distal metastasis was to bones only. All cases had received hormonal therapy as the initial therapy. Immunostaining of PSA, chromogranin A, neuron-specific enolase, carcinoembryonic antigen and vimentin were performed in five of the eight cases.〈section xml:id="abs1-2"〉〈title type="main"〉Results:Four cases were poorly differentiated, two were undifferentiated, one was a mixture of poorly differentiated and undifferentiated and one case was moderately differentiated. Of the five cases in the immunohistochemical study, three cases with an undifferentiated carcinoma component showed negative staining reactions for PSA and all cases were positive for carcinoembryonic antigen. Four of the patients died of prostate cancer. In two of these four cases, hormonal therapy was ineffective, but systemic chemotherapy and irradiation therapy had been moderately effective. The overall 3-year survival rate was 33.3%.〈section xml:id="abs1-3"〉〈title type="main"〉Conclusions:The cases of M1 prostate cancer with a serum PSA less than 10 ng/mL are almost always poorly differentiated or undifferentiated and have a poor prognosis compared with the usual M1 prostate cancer. Because hormonal therapy is ineffective in these cases, systemic chemotherapy and irradiation therapy should be chosen as the initial therapy.

    Primary signet-ring cell carcinoma of the urinary bladder inducing renal failure (2001)

    Notes: Abstract A case of primary signet-ring cell carcinoma of the urinary bladder that was found to have induced renal failure is the second such case reported in the world. Primary signet-ring cell carcinoma of the urinary bladder is a rare histologic variant of adenocarcinoma. The patient died of distant metastasis 8 months after undergoing total cystectomy. The neoplasm had a high stage at diagnosis, so the prognosis was very poor. To improve the prognosis, earlier diagnosis and establishing a regimen of chemotherapy is necessary.

    The possibility of ‘de novo’ cancer in the prostate (2005)
    Melbourne, Australia : Blackwell Science Pty
    International journal of urology 12 (2005), S. 0

    Notes: Abstract  Background:  To investigate the possibility of ‘de novo’ prostate cancer by analyzing the relationship between high grade prostatic intraepithelial neoplasia (HGPIN) and latent prostate cancer.Materials and methods:  Latent prostate cancers found at autopsy were examined and 55 cancer foci with a poorly (Gleason grade 4 and 5) or moderately (Gleason grade 3) differentiated component were selected. The 55 foci were separated into two groups: (i) foci with either a poorly or moderately differentiated component only (single differentiation group, SDG); and (ii) mixed foci with two or more types of differentiation components (mixed differentiation group, MDG). High grade intraepithelial neoplasia was defined as positive if it was observed within 2 mm from the edge of the cancer focus and the relationship between HGPIN and the two groups was investigated.Results:  The MDG had 39 cancer foci (71.0%) and there were 16 in the SDG (29.0%). There were 31 foci that were small-volume cancers (〈0.2 mL). In the MDG, 13 small-volume cancer foci were HGPIN positive, but in the SDG, none of the small-volume cancers were HGPIN positive.Conclusions:  Small-volume cancer foci without HGPIN in the SDG may be candidates for de novo prostate cancers.

    Transurethral needle ablation of the prostate: An initial Japanese clinical trial (2001)

    Notes: Abstract Objectives: Transurethral needle ablation of the prostate is a new alternative endoscopic thermal therapy that uses a low-energy radio frequency delivered into the prostatic adenoma. Herein is reported the initial clinical experience by multiple institutes in Japan of transurethral needle ablation of the prostate for the treatment of symptomatic benign prostatic hyperplasia.Methods: A total of 93 patients were treated with this technique. Transurethral needle ablation of the prostate was generally performed under low-spinal anesthesia. Before and after the procedure, international symptom score (IPSS), quality of life (QOL) score, peak urinary flow rate (Qmax), postvoid residual urine volume and prostate size were evaluated.Results: There was a reduction of IPSS of more than 50% when compared with that of pretreatment, being 51.3% (57/93 patients) and 60.2% (56/93 patients) at 3 months and 6 months after the procedure, respectively. Sixty-seven patients who were available for a 12-month follow-up period demonstrated a markedly decreased mean IPSS when compared with that measured before the treatment for a statistically significant difference (P 〈 0.01). Fifty-eight patients who were available for uroflowmetric study at 12 months exhibited a notably increased mean Qmax of 11.2 ± 4.5 mL/s, which was a statistically significant increase when compared with that found before treatment (P 〈 0.05). Although all patients suffered some degree of gross hematuria after the procedure, none of them required any specific treatment for complications.Conclusion: Transurethral needle ablation technique for the treatment of symptomatic benign prostatic hyperplasia is safe and effective. However, a much longer follow-up study is essential for fully evaluating the extended effectiveness of this technique.
