Prevalence of frailty syndrome in urological patients undergoing major elective surgical procedure due to malignancy.

Introduction: The group of elderly urological patients is growing. A majority of urological operations is performed in this group. The current model of preoperative assessment is developed to be effective in younger groups of patients but not in the elderly.

Biomarkers of epithelial-mesenchymal transition in localized, surgically treated clear-cell renal cell carcinoma.

Introduction: It has been suggested that the metastatic potential of neoplastic cells can be predicted on the basis of their biological features, including expression of proteins involved in the epithelial to mesenchymal transition (EMT). Therefore, the purpose of this work was to (1) evaluate the expression of EMT markers: ZEB2, vimentin, N-cadherin, TWIST, PTEN, survivin, E-cadherin, Ki-67 and GLUT-1, (2) assess mutation status of two genes: PIK3CA and KRAS, and (3) investigate the potential relationships between the studied biomarkers and clinicopathological factors in clear-cell renal cell carcinoma (ccRCC).

Material And Methods: Tumor tissue samples (embedded in paraffin blocks) from 159 patients undergoing radical nephrectomy were analyzed.

MCPIP1 contributes to clear cell renal cell carcinomas development.

Monocyte Chemoattractant protein-induced protein 1 (MCPIP1), also known as Regnase-1, is encoded by the ZC3H12a gene, and it mediates inflammatory processes by regulating the stability of transcripts coding for proinflammatory cytokines and controlling activity of transcription factors, such as NF-κB and AP1. We found that MCPIP1 transcript and protein levels are strongly downregulated in clear cell renal cell carcinoma (ccRCC) samples, which were derived from patients surgically treated for renal cancer compared to surrounded normal tissues. Using Caki-1 cells as a model, we analyzed the role of MCPIP1 in cancer development.

Post-Irradiation Bladder Syndrome After Radiotherapy of Malignant Neoplasm of Small Pelvis Organs: An Observational, Non-Interventional Clinical Study Assessing VESIcare®/Solifenacin Treatment Results.

BACKGROUND Radiotherapy is explicitly indicated as one of the excluding factors in diagnosing overactive bladder syndrome (OAB). Nevertheless, symptoms of OAB such as urgent episodes, incontinence, pollakiuria, and nocturia, which are consequences of irradiation, led us to test the effectiveness of VESIcare®/Solifenacin in patients demonstrating these symptoms after radiation therapy of small pelvis organs due to malignant neoplasm. MATERIAL AND METHODS We conducted an observatory clinical study including 300 consecutive patients with symptoms of post-irradiation bladder; 271 of those patients completed the study.

Histopathological assessment of residual retroperitoneal mass removed in patients after chemotherapy for non-seminomatous germ cell tumours of the testis.

Between 1990 and 1999, 182 men were treated for non-seminomatous germ cell testicular tumours. In 24 of them after chemotherapy a residual retroperitoneal mass was removed. In 14 of them additional immunohistochemical (IHC) examinations using antibodies against cytokeratins, vimentin, PLAP, CD30, AFP, βhCG, p53, and MIB-1 were performed.

Variants of SCARB1 and VDR Involved in Complex Genetic Interactions May Be Implicated in the Genetic Susceptibility to Clear Cell Renal Cell Carcinoma.

The current data are still inconclusive in terms of a genetic component involved in the susceptibility to renal cell carcinoma. Our aim was to evaluate 40 selected candidate polymorphisms for potential association with clear cell renal cell carcinoma (ccRCC) based on independent group of 167 patients and 200 healthy controls. The obtained data were searched for independent effects of particular polymorphisms as well as haplotypes and genetic interactions.

Correlation between CT perfusion and clinico-pathological features in prostate cancer: a prospective study.

Background: The aim of the study was to assess the correlation between computed tomography perfusion (PCT) parameters and PSA levels, Gleason score, and pTNM stage in patients with prostate cancer (PCa).

Material/methods: One hundred twenty-five patients with localized PCa were prospectively enrolled in the study. All patients were diagnosed due to suspicious prostate findings and elevated PSA serum levels and underwent PCT followed by core biopsy and radical prostatectomy.

Perfusion CT is a valuable diagnostic method for prostate cancer: a prospective study of 94 patients.

Purpose: The aim of this study is to assess the usefulness of perfusion computer tomography (pCT) in prostate cancer (PCa) diagnostics.

Materials And Methods: 94 patients with biopsy-proven PCa were enrolled in the study. Dynamic pCT of the prostate gland was performed for 50 seconds after an intravenous injection of contrast medium.

Value of perfusion CT parameters, microvessl density and VEGF expression in differentiation of benign and malignant prostate tumours.

The purpose of this study was to assess the correlation between parameters evaluated using computed tomography perfusion (CTP) and microvessel density (MVD), the vascular endothelial growth factor labelling index (VEGFLI), as well as known clinicopathological indicators of tumour malignancy, in non-advanced prostatic cancer. We included 110 patients with early stage prostate cancer who were subjected to CT examinations followed by radical prostatectomy between 2007 and 2011 (in this analysis we included only patients diagnosed with CT). Both in affected and in healthy tissue the following perfusion parameters were assessed: blood flow (BF), blood volume (BV), mean transit time (MTT) and permeability-surface area product (PS).

[Apocrine breast cancer in the material from Cancer Centre in Krakow. Clinical features and treatment results in patients treated between 1952 and 2002].

Unlabelled: Apocrine breast cancer is a rare type of neoplasm and accounts for approximately 0.3-4% of all breast cancers. It most frequently diagnosed in women over the age of 50.

Total number of lymph nodes and number of metastatic lymph nodes harvested during radical mastectomy did not influence early postoperative drainage volume.

Objectives: We aimed at evaluation of the influence of the extent of axillary lymph node dissection, measured by the total number of lymph nodes harvested, on the drainage volume. We also looked at the lymph node positivity (N+) and the number of metastatic axillary lymph nodes as a potential prognostic factors in this regard.

Material And Methods: We have analysed the data of 63 patients (F/M: 62/1) with breast cancer who underwent radical modified mastectomy in 2008-2009 in the single department of surgical oncology

Results: We observed no significant correlation between the 1) total number of axillary lymph nodes harvested during lymphadenectomy 2) presence of metastatic lymph nodes (node positive disease), 3) number of metastatic axillary lymph nodes and: drainage volume on the day of surgery drainage volume on three consecutive postoperative days and drainage volume from the day of surgery to drain removal.

Prognostic factors of overall survival in renal cancer patients - single oncological center study.

Introduction: The clinical course of renal cancer remains difficult to predict. Attempts to appoint new independent prognostic factors (IPFs) and comparisons of already identified ones among populations are inevitable to develop more effective prognostic instruments. The aim of this study was to evaluate IPFs of overall survival in a given population of patients with renal cancer.
