Objective: Large bladder diverticulae, i.e. with a diameter measuring at least one-third of the bladder diameter on voiding cystourethrography, constitute an unusual but serious cause of obstructive uropathy in childhood.

Background: The clinical relevance of positive molecular staging as defined by reverse transcriptase-polymerase chain reaction (RT-PCR) detections of both prostate-specific antigen (PSA) and prostate-specific membrane antigen (PSMA) transcripts in the peripheral blood (PB) of patients with prostate cancer is still debatable.

Methods: We analyzed the biochemical failure-free survival (bFFS) of prostate cancer patients with positive molecular staging who underwent immediate curative therapy (Group I, n=39) compared to prostate cancer patients who did convert their positive molecular staging by the administration of combined androgen blockade (CAB) for 12 months prior to curative treatment (Group II, n=15).

Results: The median bFFS for Group I was 9 months (95% CI 5-13 months) and was significantly lower compared to Group II (>36 months, p<0.

Background: As previously shown, the combination of standard androgen ablation therapy with somatostatin analog and dexamethasone in metastatic androgen ablation-refractory (stage D3) prostate cancer (PrCa) patients has a favorable profile of side-effects, durable objective antitumor activity (up to 60% partial response rate) and palliative effects. Bisphosphonates interfere with bone remodeling at the sites of PrCa bone metastases and have been postulated to have indirect and/or direct anti-PrCa activity.

Materials And Methods: A randomized controlled clinical trial was conducted to compare a combination of somatostatin analog (octreotide 20 mg i.

The development of resistance to anticancer therapies is a major hurdle in preventing long-lasting clinical responses to conventional therapies in hormone-refractory prostate cancer. Herein, the molecular evidence documenting that bone metastasis microenvironment survival factors (mainly the paracrine growth hormone-independent, urokinase-type plasminogen activator-mediated increase of IGF-1 and the endocrine production of growth hormone-dependent IGF-1, mainly liver-derived IGF-1 production) produce an epigenetic form of prostate cancer cells that are resistant to proapoptotic therapies is reviewed. Consequently, the authors present the conceptual framework of a novel antibone microenvironment survival factor, mainly an anti-IGF-1 hormonal manipulation for androgen ablation refractory prostate cancer (a combination of conventional androgen ablation therapy [luteinising hormone-releasing hormone agonist-A or orchiectomy]) with dexamethasone plus somatostatin analogue, which yielded durable objective responses and major improvement of bone pain and performance status in stage D3 prostate cancer patients.

Background: Inguinal lymphadenectomy has an essential role in the cure of patients with inguinal metastasis from penile cancer; however, this procedure is associated with a significant morbidity. In recent years, modified lymphadenectomy with saphenous vein preservation has been postulated to reduce morbidity. Herein, we present our recent experience with prophylactic inguinal lymhadenectomy and saphenous vein preservation in patients with invasive penile carcinoma and non-palpable inguinal lymph nodes.

Background: Severe anaemia is common in patients with metastatic, hormone-refractory prostate cancer (HRPC).

Patients And Methods: We evaluated the efficacy of epoetin beta in correcting anaemia and maintaining haemoglobin (Hb) levels in this group of patients. Patients with HRPC, bone metastases and anaemia (Hb < 12 g/dl) were included.

Purpose: Androgen ablation-refractory prostate cancer patients (stage D3) develop painful bone metastases and limited responsiveness to conventional therapies, hence the lack of universally accepted "gold standard" treatment for this poor prognosis clinical setting. We tested the safety and efficacy in stage D3 patients of the combination hormonal therapy, which combines administration of somatostatin analog and dexamethasone with standard androgen ablation monotherapy (luteinizing-hormone releasing-hormone analog or orchiectomy).

Experimental Design: Thirty eight patients with stage D3 prostate cancer (mean age 71.

Background: To determine the onset and extent of combined androgen blockade (CAB)-induced anemia in prostate cancer patients without bone involvement.

Patients And Methods: Forty-two patients with biopsy-proven prostatic adenocarcinoma [26 with stage C (T3N0M0) and 16 with stage D1 (T3N1M0)] were included in this study. All patients received CAB [leuprolide acetate (LHRH-A) 3.

The syndrome of inappropriate antidiuretic hormone secretion (SIADH) may occur in a variety of diseases, including malignancies, and can be induced by drugs. We report a case of inappropriate antidiuretic hormone syndrome associated with hormone refractory prostatic carcinoma.

Bone is the most frequent site of metastases of prostate cancer and is almost always the first and frequently the only site of metastases where disease will progress to stage D3. In addition, the number of skeletal metastatic foci is the most powerful independent prognostic factor of limited response to hormone ablation therapy and poor survival of patients with advanced prostate cancer. Furthermore, disease progression frequently occurs in the osteoblastic metastases, even though androgen ablation therapy still provides adequate and sustained control of disease at the primary site.

To improve median survival of patients with prostate cancer that has metastasized to bone, we need to better understand the early events of the metastatic process in skeleton and develop molecular tools capable of detecting the early tumor cell dissemination into bones (micrometastasis stage). However, the initial phase of tumor cell dissemination into the bone marrow is promptly followed by the migration of tumor cells into bone matrix, which is a crucial step that signals the transformation of micrometastasis to macrometastasis stage and clinically evident metastasis. The migration of cancer cells into bone matrix requires the activation of local bone resorption.

The local microenvironment at the sites of cancer metastases protects tumour cells from anticancer drug-induced apoptosis via mechanisms, such as soluble growth factors and cytokines. The concept of antisurvival factor (ASF) therapy as a component of anticancer treatments aims at neutralising the protective effect conferred upon cancer cells by the survival factor(s) derived by the local microenvironment, in order to enhance the sensitivity and/or reverse the resistance of tumour cells to other anticancer therapeutic strategies. Herein, we review the translation of this concept from ex vivo studies to clinical applications in the setting of prostate cancer refractory to androgen ablation (stage D3).
