Advantages and Disadvantages of Bone Protective Agents in Metastatic Prostate Cancer: Lessons Learned

2016

Nine out of ten metastatic prostate cancer (PCa) patients will develop osseous metastases. Of these, every second will suffer from skeletal-related events (SRE). SRE are associated with an increased risk for death, which is markedly increased in the presence of pathological fracture. Moreover, health insurance costs nearly double in the presence of SRE. Zoledronic acid and denosumab are both approved drugs for the prevention or delay of SRE in castration-resistant prostate cancer (CRPC) patients with osseous metastases. However, long-term treatment with one of these two drugs is associated with the development of medication-related osteonecrosis of the jaw (MRONJ). Routine inspections of th…

Evaluation of TKTL1 as a biomarker in serum of prostate cancer patients.

2016

Introduction Monocyte associated transketolase-like 1 (TKTL1) as a cancer biomarker has become popular with alternative practitioners, but plays no role in conventional medicine. This investigation evaluates the potential of serum TKTL1 as a biomarker for prostate cancer. Material and methods Patients (n = 66) undergoing curative radical prostatectomy (RPE) for biopsy-pro-ven PCa were included in the study. Controls (n = 10) were healthy, age-matched, male volunteers. 10 ml of peripheral blood was drawn from patients several days before surgery and from controls. Serum TKTL1 was measured using the ELISA method. Results The median age at tumor diagnosis was 66 years and median serum PSA was …

The diagnostic plot: a concept for identifying different states of iron deficiency and monitoring the response to epoetin therapy.

2005

Iron balance is regulated by the rate of erythropoiesis and the size of the iron stores. Anemia that accompanies infection, inflammation, and cancer (anemia of chronic disease) features normal or increased iron stores, although patients may have functional iron deficiency, namely, an imbalance between iron requirements of the erythroid marrow and the actual supply. The proportion of hypochromic red cells and the hemoglobin content of reticulocytes are direct indicators of functional iron deficiency. Biochemical markers, especially the soluble transferrin receptor/log ferritin ratio (ferritin index), are useful indicators of the iron supply to erythropoiesis. The relationship between functio…

Intraoperative peripheral frozen sections do not significantly affect prognosis after nerve-sparing radical prostatectomy for prostate cancer

2010

Study Type – Therapy (outcomes research) Level of Evidence 2b What’s known on the subject? and What does the study add? We hypothesized that taking intraoperative frozen section (FS) biopsies of the peripheral margins of resection during radical prostatectomy would allow an intraoperative systematic scan of resection margins. In the case of positive FS, extended resection could be performed with the aim of completely excising residual tumour, improving biochemical recurrence-free survival of patients with positive surgical margins at the inked specimen. To our knowledge, the prognostic value of achieving a negative resection status by systematically taking intraoperative FS of the periphera…

CT-guided nephrostomy–An expedient tool for complex clinical scenarios

2018

Abstract Introduction & objectives Percutaneous nephrostomy [ 1 ] has emerged as a pivotal approach in the therapeutic management of the obstructed urinary tract. A consecutive incorporation of ultrasonic and radiographic guidance, the approach experienced an almost ubiquitious distribution while most centers currently applying either one or both of these tools jointly. However, success of ultrasound-guidance is limited in obese patients and non-dilated uropathy. In turn, fluoroscopy usually requires an opacification of the urinary collecting system by intravenous or antegrade contrast media injection, which might be harmful for already impaired renal function, raise intrapelvic pressure an…

Nationwide analysis on the impact of socioeconomic land use factors and incidence of urothelial carcinoma

2017

Incidence rates for urothelial carcinoma (UC) have been reported to differ between countries within the European Union (EU). Besides occupational exposure to chemicals, other substances such as tobacco and nitrite in groundwater have been identified as risk factors for UC. We investigated if regional differences in UC incidence rates are associated with agricultural, industrial and residential land use.Newly diagnosed cases of UC between 2003 and 2010 were included. Information within 364 administrative districts of Germany from 2004 for land use factors were obtained and calculated as a proportion of the total area of the respective administrative district and as a smoothed proportion.

Risk factors, complications and management of lymphocele formation after radical prostatectomy: A mini‐review

2019

Lymphocele formation is the most common adverse event of pelvic lymphadenectomy during radical prostatectomy for prostate cancer. Previous studies failed to favor one surgical technique over the other in terms of minimizing its rate. Data on risk factors for its development are still conflicting and warranting further research. In this mini-review, we aimed to scrutinize available evidence on these aspects and outline current achievements in lymphocele prevention approaches.

Predictors for clinically relevant Gleason score upgrade in patients undergoing radical prostatectomy

2011

Study Type – Diagnostic (exploratory cohort) Level of Evidence 2b What’s known on the subject? and What does the study add? Clinically relevant GSU in the prostatectomy specimen is a common phenomenon. Clinically relevant GSU occurs in one of three patients with clinically ‘very’ low-risk PCa, and a low number of biopsy cores is the key negative predictor. OBJECTIVE • To evaluate clinical predictors for Gleason score upgrade (GSU) in radical prostatectomy (RP) specimen, especially in patients with ‘very’ low risk PCA (T1c and biopsy Gleason score ≤6 and PSA <10 ng/ml and ≤2 positive biopsy cores and PSA density <0.15).

AR-V7 Protein Expression in Circulating Tumour Cells Is Not Predictive of Treatment Response in mCRPC

2019

&lt;b&gt;&lt;i&gt;Introduction:&lt;/i&gt;&lt;/b&gt; Androgen receptor variant 7 (AR-V7) plays an important role in the progression of castration-resistant prostate cancer (CRPC) and has shown potential as a predictive biomarker in circulating tumour cells (CTCs) isolated from the bloodstream in terms of a liquid biopsy. Studies have shown that AR-V7 is a potential surrogate for selecting drug classes for systemic treatment by detecting nuclear AR-V7 by immunofluorescence or measuring AR-V7 messenger RNA by quantitative PCR. Here, we assessed the predictive value of AR-V7 detected by classical immunohistochemistry (IHC) for treatment response. &lt;b&gt;&lt;i&gt;Methods:&lt;/i&gt;&lt;/b&gt; C…

Systemic treatment of bone metastases in castration-resistant prostate cancer (CRPC): pre-clinical to clinical point of view

2015

Abstract Prostate cancer (PCa) is the most common cancer and the third most common cause of cancer related mortality in men in the United States. Hormonal therapy remains the most effective therapy for patients with advanced prostate cancer, inhibiting proliferation and inducing apoptosis in tumor cells. Unfortunately, after short-term remissions (18–24 months), surviving tumor cells recur with castrate resistant prostate cancer (CRPC) with inevitable progression, development of metastases mainly in bone, and death within 2–3 years in most men. Improved understanding of the molecular basis underlying bone-specific metastases and resistance to ADT or chemotherapy will facilitate the rational…

Indications for preoperative prostate biopsy in patients undergoing radical cystoprostatectomy for bladder cancer.

2008

We determined indications for preoperative prostate biopsy in patients undergoing radical cystoprostatectomy for bladder cancer.Of 316 cystoprostatectomy specimens concomitant prostate cancer was diagnosed in 21.5%. Prostate cancer was diagnosed preoperatively in 24% of cases (evident prostate cancer), 32% were suspicious for prostate cancer but no biopsy was done (suspected prostate cancer) and in 44% prostate cancer was incidental. Patients were stratified into probability groups of intermediate/high risk prostate cancer by digital rectal examination and prostate specific antigen. The incidence of unfavorable histopathology was determined in each group.Of prostate cancers 85% were organ c…

Genetic profiling in der Diagnostik des hereditären Prostatakarzinoms – wo stehen wir?

2018

ZusammenfassungProstatakrebs weist im Vergleich zu anderen Tumorentitäten ein heterogenes genetisches Profil auf. Dementsprechend sind auch Mutationen, die das Prostatakarzinomrisiko erhöhen, vielfältig. Manche genetische Varianten fallen bei der Risikoerhöhung nur milde ins Gewicht. Andere Genmutationen (BRCA1 /2; HOXB13) erhöhen das Risiko jedoch teils erheblich. Insgesamt ist die Wahrscheinlichkeit für einen nicht familiär vorbelasteten Mann, ein Träger von Mutationen zu sein, welche mit einem erhöhten PCa-Risiko assoziiert sind, niedrig. Ist aber die familiäre Belastung durch in jungem Alter erkrankte Verwandte oder eine bereits bekannte Mutation in der Familie vorhanden, so steigt auch…

Moreover, we explored parameters for the failure of percutaneous lymphocele drainage. Methods The incidence of symptomatic lymphoceles in patients with prostate cancer who underwent radical retropubic prostatectomy with pelvic lymph node dissection in our department between 2008 and 2013 was investigated retrospectively. The occurrence of lymphoceles was correlated with several clinical and histopathological parameters. In addition, logistic regression analysis was performed to assess the value of independ…

Anemia of Chronic Disease: Pathophysiology and Laboratory Diagnosis

2005

Classic iron deficiency (ID) does not represent a challenge for the laboratory and physicians. The anemia that accompanies infection, inflammation, and cancer, commonly termed anemia of chronic disease (ACD), features apparently normal or increased iron stores. However, 20% of these patients have iron-restricted erythropoiesis (functional ID), an imbalance between the iron requirements of the erythroid marrow and the actual iron supply. Functional ID leads to a reduction in red cell hemoglobiniza-tion, causing hypochromic microcytic anemia. The diagnosis of functional ID in real time is based on measuring the hemoglobin content of reticulocytes. An examination of the biochemical markers of …

Deregulation of E2-EPF Ubiquitin Carrier Protein in Papillary Renal Cell Carcinoma

2011

Molecular pathways associated with pathogenesis of sporadic papillary renal cell carcinoma (PRCC), the second most common form of kidney cancer, are poorly understood. We analyzed primary tumor specimens from 35 PRCC patients treated by nephrectomy via gene expression analysis and tissue microarrays constructed from an additional 57 paraffin-embedded PRCC samples via immunohistochemistry. Gene products were validated and further studied by Western blot analyses using primary PRCC tumor samples and established renal cell carcinoma cell lines, and potential associations with pathologic variables and survival in 27 patients with follow-up information were determined. We show that the expressio…

Incidence, Clinical Symptoms and Management of Rectourethral Fistulas After Radical Prostatectomy

2009

Rectourethral fistula is a rare but severe complication after radical prostatectomy and there is no standardized treatment. We retrospectively evaluated the incidence, symptoms and management of rectourethral fistulas based on our experience.From 1999 to 2008 we performed 2,447 radical prostatectomies. Patients in whom postoperative rectourethral fistulas developed were identified. Based on the therapeutic approach patients were categorized into group 1-conservative treatment, group 2-colostomy with or without surgical closure and group 3-immediate surgical closure without colostomy.Rectourethral fistulas developed in 13 of 2,447 patients (0.53%) after radical prostatectomy.

2013

&lt;b&gt;&lt;i&gt;Background:&lt;/i&gt;&lt;/b&gt; The objective was to investigate whether two-dimensional intraoperative neuromonitoring (IONM) of pelvic autonomic nerves has the potential to predict erectile function (EF) following surgery for rectal cancer. &lt;b&gt;&lt;i&gt;Methods:&lt;/i&gt;&lt;/b&gt; A consecutive series of 17 sexually active male rectal cancer patients undergoing IONM-based nerve-sparing low anterior rectal resection were evaluated prospectively. IONM was performed by electric stimulation of the pelvic splanchnic nerves with concomitant electromyography of the internal anal sphincter and cystomanometry. Sexual function was assessed using a validated questionnaire. &l…

Clinical Scenario: Unexpected Positive Nodes at Radical Cystectomy

2014

Positive lymph nodes are found in 20–30 % of patients undergoing radical cystectomy for bladder cancer. Their presence is associated with poor survival in the majority. Super-extended lymph node dissection is recommended in the presence of positive lymph nodes to possibly improve oncologic outcome. In patients with unsuspicious lymph nodes, dissection should be performed at least up to the common iliac vessels. Even in the presence of lymph node metastases cystectomy is indicated to reduce local tumor complications. The type of urinary diversion should not be altered by lymph node positivity unless the diversion would otherwise negatively influence the extent of the procedure.

Detection of iron restriction in anaemic and non-anaemic patients: New diagnostic approaches.

2017

Objective The aim of this study was to detect iron restriction in non-anaemic patients and iron-restricted erythropoiesis (IRE) in patients with anaemia. Method Haematologic indices and biochemical markers of iron deficiency (ID) were determined using the clinically accepted cut-off level for serum ferritin of ≤30 μg/l as reference of ID. To evaluate the prevalence of iron restriction and IRE in patients with higher ferritin levels we used the thresholds of the markers of ID as reference. Results In the anaemic group 17.1% of patients with ferritin levels >30 μg/l had IRE. The number of patients with IRE declined with increasing ferritin concentration. Approximately 14% of patients without …
