Human Prostate Tissue Model to Maintain and Study Prostate Cancer Stem Cells

Benign Prostatic HyperplasiaProstate Carcinoma

This pilot research trial studies the use of a human prostate tissue model to maintain and study prostate cancer stem cells. A human prostate tissue model uses leftover tissue that was removed during surgery from patients with non-cancerous enlargement of the prostate (benign prostatic hyperplasia) and may create an environment similar to the natural environment of the human body. Prostate cancer stem cells are cells that cause cancer to grow. Using real tissue to create an environment to study stem cells may help doctors learn more about how they work and how they respond to treatments.

Interest of a Systematic Assessment of the Treatment of LUTS in the Management of BPH

Benign Prostatic Hyperplasia

The high level of unsatisfactory outcome observed in patients treated for LUTS associated with BPH with respect to the different existing therapeutic options strongly emphasizes the need for treatment optimisation in daily practice by a careful LUTS monitoring and treatment adjustment when needed. The poorer outcome observed in patients for whom treatment has been initiated recently suggests that the duration of the disease itself may influence the patient satisfaction.To achieve this goal, we propose to systematically assess LUTS associated with BPH in patients treated for at least 6 months and to assess whether an alpha-blocker therapy initiation/modification may improve the outcome in case of persisting symptoms. We also investigate the influence of the symptom duration on the frequency of unsatisfactory outcome.

X-Ray Mammography Standard of Care Protocol

Breast CancerInvasive Carcinoma3 more

Background: X-ray mammography is the standard method for breast cancer screening. It is a noninvasive test using x-rays to take pictures of breast tissue and detect any abnormalities. The National Institutes of Health (NIH) Clinical Center has a breast imaging unit that has been accredited by the American College of Radiology. To maintain accreditation, the unit must recruit a certain number of women to have clinical mammograms each year in order to maintain a high level of clinical skills and experience for the radiologists and technologists. Objectives: - To create a state-of-the-art mammography unit at the NIH Clinical Center in order to maintain American College of Radiology accreditation of the NIH breast imaging facility. Eligibility: - Women who are eligible for breast cancer screening because of family cancer history, genetic test results, or previous instances of cancer. Participants may not be pregnant or nursing at the time of the screening. Design: Participants will provide a brief medical history on arrival at the NIH breast imaging unit. Each participant will have a standard mammogram performed by a radiology technician. If the study is normal, participants will be told that no further evaluation will be performed. If the results indicate a need for further imaging or tissue biopsy, participants may elect to return to the care of their primary physician or to receive further follow-up at the NIH Clinical Center.

Correlation Between Hysteroscopic Diagnosis of Endometrial Hyperplasia and Histopathological Examination...

Endometrial HyperplasiaEndometrial Neoplasms

A prospective cohort study at a Tertiary University Hospital. From January to December 2018, we enrolled women with the following criteria: abnormal uterine bleeding in post-menopause, endometrial thickening in pre-or post-menopause; tamoxifen usage. Patients underwent office hysteroscopy with a 5-mm continuous-flow hysteroscope and endometrial biopsies were taken using miniaturized instruments. Senior operators had to foresee histopathological diagnosis using a questionnaire. Histopathological examination was conducted to confirm the diagnosis.

Performance of White Light, NBI and Iodine Staining Endoscopy in the Diagnosis of Esophageal Lesions...

Mild Dysplasia of EsophagusModerate Dysplasia of Esophagus3 more

The investigators aim to evaluate the performance of Narrow Band Imaging (NBI) endoscopy in Esophageal Squamous Cell Carcinoma (ESCC) screening, as compared to the currently used White Light Endoscopy (WLE) and Lugol's Iodine Staining Endoscopy (ISE). NBI is a simple, safe and non-invasive technique, which can provide real-time optical staining for suspicious lesions. This trial is designated to enroll 10000 participants from five centers located in different regions (North, West and South) in China, which would provide real-world evidence for the recommendation of endoscopic diagnostic technique used in ESCC screening projects.

The Effect of Human Prostate Tissue on Platelet Activation

Prostate HyperplasiaCoagulation; Intravascular1 more

Transurethral resection of the prostate (TURP) is a common and standard urological surgical procedure for managing benign prostatic hyperplasia (BPH). Although surgical technology improved in recent decades, severe complications such as TURP syndrome, hematuria, and postoperative hemorrhage were still considerable. Coagulopathy is one of rare but devastating complication which may contribute to bleeding during and after TURP. Although the exact pathophysiological condition of coagulopathy is not clear, there are several possible mechanisms of TURP associated coagulopathy including: urokinase- (u-PA) and tissue-type plasminogen activator (t-PA)-related fibrinolysis; absorption of irrigating fluid associated dilutional coagulopathy; release of prostatic particles rich in tissue thromboplastins into the circulation causing secondary fibrinolysis and disseminated intravascular coagulopathy (DIC); sepsis with DIC associated with bacteria entering the circulation due to prostatic venous sinuses opening and the using of high pressure irrigation. On the other hand, platelet are essential to hemostasis and thrombosis and its activation also contributes to leukocyte recruitment and DIC. Furthermore, previous studies demonstrated that activated platelets could express TLR4, CD40L, P-selectin and induce platelet-leukocyte aggregation (PLA), which were considered important for systemic inflammatory responses and DIC development. Currently, no study investigating the association of prostate particle and platelet activation. Here, we tested the hypothesis that prostate tissue may induce inflammatory responses through platelet activation by measuring the expression of TLR4, CD40L, P-selectin and PLA on platelets.

Screening for Anal Cancer in Women With High-grade Vulvar Dysplasia or Vulvar Cancer.

Vulvar CancerCervical Cancer5 more

Almost half of all women will develop an HPV infection in their lifetime. While most infections are naturally asymptomatic or cleared by the immune system, some persist and can lead to the development of cervical, vulvar, or anal lesions and eventually cancer. Screening regimens for these lesions are currently only in place for the cervix through regular Pap tests. These Pap tests usually involve an examination of the vulva -however, no screening procedures exist for anal cancer for women. Several studies have suggested that women with existing gynecological lesions are more likely to develop anal lesions and anal cancer. Here the investigators propose a multi-center study which seeks to screen for and treat anal cancer in women over the age of 40 with vulvar lesions and a stable immune system. The investigators will achieve this through performing anal Pap smears on eligible women and conducting High Resolution Anoscopy (HRA) and appropriate treatment procedures on those with abnormal anal cells. With enough evidence, there may be an indication to establish regular anal cancer screening measures in this potentially underserved population. Hypothesis: The investigators hypothesize that at least 40% of women with vulvar cancer or VIN2/3 will have abnormal anal cytology. 35% of the population will be hrHPV DNA positive and 11% will additionally have AIN2/3. This prospective study may lay the groundwork for routine anal screening regimens in Ontario and help shift health policy to treat this population.
