1/926. Interposition of sural nerve restores function of cavernous nerves resected during radical prostatectomy.

    PURPOSE: The permanent loss of erectile function when both neurovascular bundles are widely resected at radical prostatectomy as well as the successful use of autologous nerve grafts in reconstructive surgery led us to perform bilateral nerve grafts in an effort to restore erectile function in potent patients treated for prostate cancer who underwent radical retropubic prostatectomy and resection of both neurovascular bundles. MATERIALS AND methods: Radical retropubic prostatectomy with deliberate resection of both neurovascular bundles was recommended for high grade, locally extensive prostate cancer in 9 select, sexually active men who reported normal erectile function. After the prostate was removed but before vesicourethral anastomosis an autologous sural nerve graft was interposed between the divided ends of the cavernous nerves bilaterally. Erectile function was monitored by patient interview, questionnaire and nocturnal penile tumescence testing after the operation. RESULTS: Four to 5 months postoperatively patients noticed slowly improving spontaneous erections, as manifested by mild tumescence regularly every several hours. Nocturnal penile tumescence testing with the RigiScan device at 4 to 6 months in 2 cases revealed erections that approached minimal criteria for normalcy. Approximately 14 months after surgery a rigid erection sufficient for penetration and intercourse developed in 1 patient. He described this event as "an erection of substance-hard, not just fluffy." CONCLUSIONS: We have developed a technique using sural nerve grafts to restore continuity of the cavernous nerves, which are resected during radical prostatectomy. The early return of spontaneous partial erections in our patients suggests that interposition nerve grafts may enhance the recovery of erectile function when the neurovascular bundles are resected.

2/926. Tc-99m HDP uptake in cardiac amyloidosis.

    amyloidosis is characterized by the soft-tissue deposition of amyloid protein. It may occur as a primary disorder but more often is seen as a manifestation of chronic illness. Scattered reports of the affinity of amyloid for bone scanning agents have appeared over many years. Isolated cardiac uptake of Tc-99m HDP is described in a patient with biopsy-proved cardiac amyloidosis on a background of tuberculosis, prostate cancer, and coronary artery disease.

3/926. Novel concept of antisurvival factor (ASF) therapy produces an objective clinical response in four patients with hormone-refractory prostate cancer: case report.

    BACKGROUND: osteoblasts and osteoblast-derived survival growth factors, such as insulin-like growth factor i (IGF I), inhibit chemotherapy apoptosis of prostate cancer cells, thereby producing cytotoxic drug-resistant tumor growth, in vitro. methods: We tested a novel therapeutic approach, referred to as antisurvival factor (AFS) therapy, that aimed at reduction of osteoblast-derived IGFs, using dexamethasone (4 mg per os, qD) and growth hormone (GH)-dependent liver-derived IGFs, using a somatostatin-analog (lanreotide, 30 mg, intramuscularly (i.m.), q14D) in combination with triptorelin (3.75 mg, intramuscularly, q28D) to produce a clinical response in 4 patients with progressing hormone-refractory prostate cancer. RESULTS: The patients given ASF therapy exhibited an excellent improvement of clinical performance and a decline of prostate-specific antigen (PSA) within 2 months of ASF therapy. One of them experienced excellent clinical response (normalization of PSA), two experienced good clinical response (decline of PSA of more than 50%), and one experienced stabilization (decline of PSA of less than 50%). CONCLUSIONS: We conclude that this novel concept of combination therapy, using ASF with hormone ablation, is a promising salvage therapy that should be further assessed with a randomized clinical trial.

4/926. Chronic creatine kinase elevation not associated with HMG-CoA reductase inhibitor treatment.

    OBJECTIVE: To report a case of chronically elevated creatine kinase (CK) concentration that is possibly associated with renal insufficiency and prostatic carcinoma. The goal is to raise awareness among clinicians who monitor CK concentrations in patients receiving hydroxymethylglutaryl-coenzyme a (HMG-CoA) reductase inhibitors. CASE SUMMARY: Because of an elevated CK concentration, a 64-year-old African-American man with a history of chronic heart disease and renal insufficiency was assessed for possible myositis relating to his treatment with HMG-CoA reductase inhibitors. However, an association between the elevated enzyme concentration and drug treatment could not be clearly established. The patient was subsequently diagnosed with prostatic cancer and underwent a radical retropubic prostatectomy. The CK enzyme concentration declined following the surgery despite continuation of the drug therapy. DISCUSSION: CK is relatively nonspecific because of its wide distribution in human tissues. Although several findings of elevated CK concentrations, particularly the CK-BB isoenzyme, in patients with carcinoma or chronic renal insufficiency have been documented, these may not be common knowledge among clinicians. This case report provides an example of an unusually high CK enzyme concentration that may be linked to prostatic carcinoma and renal insufficiency. CONCLUSIONS: It is important to be aware of different causes for CK enzyme concentration elevation, especially when it is used as a monitoring parameter during HMG-CoA reductase inhibitor treatment. In a case of persistent elevated CK enzyme concentration without evidence of myositis, renal insufficiency may be a contributing factor and malignancy must be ruled out.

5/926. Perineal approach to radical prostatectomy in kidney transplant recipients with localized prostate cancer.

    Close urologic follow-up of renal transplant candidates and recipients often reveals prostate carcinoma at an early stage. Two patients who underwent renal transplantation for end-stage disease also underwent radical perineal prostatectomy for localized prostate carcinoma, 3 years after grafting in 1 patient and 4 years before grafting in the other. The perineal approach to prostatectomy may facilitate later renal transplantation and avoid allograft damage.

6/926. Interstitial microwave thermoablation for localized prostate cancer.

    The conventional treatment for localized prostate cancer can be associated with significant morbidity and cost. Interstitial microwave thermoablation is a minimally invasive procedure used experimentally to treat selected patients with failed radiation therapy of prostate cancer at our institution. Preliminary results in these patients suggest that this treatment might be a useful alternative in selected patients with previously untreated localized prostate cancer. In this report we describe the first use of percutaneous transperineal interstitial microwave thermoablation to treat a case of primary prostate cancer. There were no treatment complications. At 18 months the patient's serum prostate-specific antigen remains undetectable, and his prostate biopsy shows no evidence of malignancy. These very preliminary but exciting results in this single patient suggest that this experimental technique should be explored further.

7/926. Adenosquamous carcinoma of the prostate: case report with dna analysis, immunohistochemistry, and literature review.

    We diagnosed prostatic adenosquamous carcinoma by prostate core needle biopsy in a 55-year-old man with no history of prostate cancer. The prognosis, dna analysis, and histogenesis of this extremely rare tumor are controversial. To our knowledge, this is the first case of adenosquamous carcinoma diagnosed by core needle biopsy in a patient with no history of prostate cancer or hormonal therapy. We performed immunohistologic and dna analysis to further characterize this cancer. The clinical presentation and abnormal dna analysis portend an aggressive course.

8/926. Use of complementary and alternative medicine in hawaii cancer patients.

    This research investigated complementary and alternative medicine (CAM) use by Hawai'i cancer patients. Thirty-six percent of patients used CAM, most commonly religious/spiritual therapy and herbal treatments. CAM use was linked with younger age, female gender, Catholic religion, and more education. More research is needed to inform decision-making.

9/926. Bilateral sphenoid wing metastases of prostate cancer presenting with extensive brain edema.

    A 76-year-old man insidiously developed diffuse neurological symptoms: cognitive decline, dysphagia, dysphasia and mental disturbance. Computed tomography of the cranium revealed widespread bilateral brain edema and symmetrical bilateral sphenoid wing hyperostosis. Adjacent to the hyperostosis that resembled skull base meningiomas, two separate parenchymatous temporal lobe lesions enhancing with contrast medium were observed. The patient had earlier been diagnosed to have prostatic carcinoma. dexamethasone therapy resulted in discontinuation of the neurological symptoms. The diagnosis of metastasized adenocarcinoma of the prostate was confirmed histologically on autopsy after a sudden death from pneumonia. Intracranial metastases of prostate cancer may have a predilection site at the sphenoid wing, and can mimic a skull base meningioma. Intracranial spread of prostatic adenocarcinoma should be considered in elderly men as a treatable cause of gradual neurological deterioration, especially if cranial malignancy or hyperostosis is found.

10/926. Solitary fibrous tumour of the prostate.

    Solitary fibrous tumours are rare, benign neoplasms that are most commonly found in the pleura and less commonly on other serosal surfaces. Their cell of origin and aetiology are uncertain. A case of solitary fibrous tumour of the prostate is presented. We believe this to be the first case of this lesion to arise in this gland. Solitary fibrous tumours of the prostate may be confused with granulomatous prostatitis or carcinoma as all three may present with a nodule on rectal examination and appear as a hypoechoic nodule on transrectal ultrasound.
