CONTEXT: Renal transplantation is the gold standard renal replacement therapy in end-stage renal disease owing to its superior survival and quality of life compared with dialysis. When the potential recipient has a history of cancer, the waiting period before radiotherapy is usually based on the Cincinnati Registry. OBJECTIVE: To systematically review all available evidence on the risk of cancer recurrence in end-stage renal disease patients with a history of urological cancer...

Small cell carcinomas (SCC) make up only 1% of malignancies of the prostate. Reports of several case series have described outcomes of surgery and chemotherapy for SCC of the prostate, but few reports address radiotherapy. We treated a case of SCC of the prostate with intensity-modulated radiation therapy (IMRT) consisting of 70 Gy administered in 35 fractions followed by hormonal therapy using only luteinizing hormone-releasing hormone (LH-RH) agonist. The tumor volume decreased remarkably by 4 months after IMRT...

BACKGROUND: Curative intent treatments for malignancies using radiation therapy while achieving longer disease-free survivals, may also lead to solid second malignancies, a dreaded late complication. Both in-field as well as out-field second malignancies are encountered and lead to diagnostic dilemma, and delay in treatment. MATERIALS AND METHODS: Details of a case of rare, in-field, radiation induced leiomyosarcoma, a rare soft tissue sarcoma, in a treated case of high risk carcinoma of prostate, who presented to our tertiary care centre was retrieved and analysed...

Small cell carcinoma of the prostate (SCCP) is rare in clinical practice. It is often accompanied with the syndrome of inappropriate antidiuretic hormone secretion (SIADH). We present a case of SCCP with SIADH that was successfully treated with radiotherapy in the metastatic lymphnodes and prostate. The patient was an 81-year-old male with a castrate-resistant prostate cancer (CRPC) with invaded rectum and multiple metastases of pelvic lymphnodes. Hyponatremia was present. After radiotherapy, serum sodium increased and neuron-specific enolase (NSE) decreased...

INTRODUCTION: Worldwide, bacterial resistance to antibiotic therapy is a major concern for the medical community. Antibiotic resistance mainly affects Gram-negative bacteria that are an important cause of lower urinary tract infections (LUTIs). Pelvic irradiation for prostate cancer is a risk factor for LUTIs. Cranberry extract is reported to reduce the incidence of LUTIs. The prophylactic role of an enteric-coated, highly standardized cranberry extract (VO370(®)) in reducing LUTI episodes, urinary discomfort, and nonsteroidal anti-inflammatory drug (NSAID) and antibiotic use during radiotherapy for prostate carcinoma was evaluated...

Metastatic spinal disease most frequently arises from carcinomas of the breast, lung, prostate, and kidney. Management of spinal metastases (SpM) is controversial in the literature. Recent studies advocate more aggressive surgical resection than older studies which called for radiation therapy alone, challenging previously held beliefs in conservative therapy. A literature search of the PubMed database was performed for spinal oncology outcome studies published in the English language between 2006 and 2016...

Metastatic prostatic carcinoma commonly involves bones and extra pelvic lymph nodes. CNS involvement is unusual and particularly the occurence of leptomeningeal metastasis is extremely rare, with few cases described in the literature.1 The reported incidence at autopsy vary from 0.6 to 4.4 percent.2 We report a 65 year old male who presented with multiple cranial nerve palsies due to leptomeningeal metastasis in carcinoma prostate treated with orchidectomy and planned for radiotherapy and antiandrogen therapy...

For metastatic carcinomas of the urinary bladder and prostate, systemic therapy is of primary importance. Due to technological advances in radiation oncology such as stereotactic radiotherapy, intensity-modulated radiotherapy, interstitial radiotherapy, and the combination of radiotherapy and chemotherapy, pelvic irradiation can nowadays be carried out effectively and without the risk of major side effects. New data from other tumor entities and retrospective analyses suggest that the use of these technologies can lead to a clinical benefit in terms of improvement in quality of life, local control, and overall survival...

Cancers have increasing threat to human health due to the limited treatment efficacy of chemotherapy and radiotherapy with a series of toxicity and side effects; therefore, the development and utilization of natural products with potential preventive and therapeutic efficacy, and less toxicity and side effects will be beneficial to promote the health of cancer patients. In this article, the activity of ampelopsin as a natural flavonoid and its underlying molecular mechanisms for the prevention and treatments of hepatic carcinoma, breast cancer, prostate cancer and melanoma through inhibiting cell proliferation, accelerating apoptosis, inducing reactive oxygen species (ROS) generation and endoplasmic reticulum (ER) stress, suppressing angiogenesis, invasion and metastasis, and synergizing the efficacy of other anti-cancer drugs have been summarized...

BACKGROUND: Population-based data on the development of kidney cancer as a second malignant neoplasm following the diagnosis of other common malignancies are rare. This clinical scenario has been evaluated within the Surveillance, Epidemiology, and End Results (SEER) database. MATERIALS AND METHODS: The SEER-9 database (1973-2013) was queried using the SEER*Stat program to determine the standardized incidence ratios (SIRs) of kidney cancer development following each one of 10 common invasive malignancies (colorectal, breast, prostate, lung, thyroid, corpus uteri, urinary bladder, kidney/renal pelvis, cutaneous melanoma, and non-Hodgkin lymphoma)...

PURPOSE: The purpose of this work is to apply a novel inverse optimization approach, based on utilization of quantitative imaging information in the optimization function, to prostate carcinoma. MATERIALS AND METHODS: This new inverse optimization algorithm relies upon quantitative information derived from computed tomography (CT) imaging studies. The Hounsfield numbers of the CT voxels are converted to physical density, which in turn is used to calculate voxel mass and the corresponding integral dose, by summation over the product of dose and mass in each dose voxel...

Prostate cancer is the most common malignancy of men in the United States. Small-cell carcinoma (SCC), which typically presents as an aggressive lung malignancy, is a rare diagnosis within the setting of prostate cancer pathology. Due to its limited prevalence, little information regarding the treatment and prognosis of this disease in large populations is available. To date our current knowledge base is largely limited to case reports and retrospective case reviews. The mainstay of treatment for this particular histology most often involves a multimodality approach utilizing chemotherapy in conjunction with radiation therapy, androgen deprivation therapy, or prostatectomy...

INTRODUCTION: Prostate specific membrane antigen (PSMA) positron emission tomography (PET) is an emerging imaging modality in prostate cancer. However, (68) Ga-PSMA-PET may also have diagnostic utility in the setting of renal cell carcinoma (RCC). We investigate the differential role of (18) F-fluorodeoxyglucose (FDG) and PSMA-PET/CT scanning in patients with oligometastatic RCC. In particular, we focus on the utility of PSMA-PET for diagnostic evaluation of isolated or limited metastases planned for local surgery or radiation, as well as the potential utility of PSMA-PET for therapeutic response assessment in patients receiving stereotactic ablative body radiotherapy (SABR)...

PURPOSE: Ultrasound (US) is a noninvasive, nonradiographic imaging technique with high spatial and temporal resolution that can be used for localizing soft-tissue structures and tumors in real-time during radiotherapy (inter- and intra-fraction). A detailed methodology integrating 3D-US within RT is presented. This method is easier to adopt into current treatment protocol than current US based systems and reduces user variability for image acquisition, thus eliminating transducer induced changes that limit CT planning system...

INTRODUCTION: Cyclin B1 is important in the cell cycle progression from G2 to M phase. Cyclin B1 binds to CDC2, which then becomes dephosphorylated and gets relocated to the nucleus, ensuring the transition toward mitosis. AIM: Over expression of Cyclin B1, has been reported more recently in breast, colon, prostate, oral and esophageal carcinomas. Thus, the aim of the present study was to examine the expression of Cyclin B1 in hyperplasia, dysplasia and Oral Squamous Cell Carcinomas (OSCC)...
