Filter by:This clinical trial studies mammography and targeted ultrasound with or without whole-breast ultrasound or contrast-enhanced magnetic resonance imaging (MRI) in finding out the extent of disease before surgery in patients with newly diagnosed breast cancer. New diagnostic imaging procedures, such as whole-breast ultrasound or contrast-enhanced MRI, may help find out how far breast cancer has spread. It is not yet known whether mammography and targeted ultrasound are more effective with or without whole-breast ultrasound or contrast-enhanced MRI in finding out how far breast cancer has spread.
This is a bridging trial of the recombinant HPV 16/18 bivalent vaccine manufactured by Xiamen Innovax Biotech CO., LTD.The primary objective of this study is to evaluate the immunogenicity (type specific IgG antibody) and safety of the tested vaccine administered in girls aged 9-17 years is non-inferior to young healthy adults of 18-26 years according to the standard 3-dose schedule (0,1,6 months). Meanwhile, this study tries to compare the difference of safety and immunogenicity among different schedules (0-6m vs 0-1-6m).
Objectives: To identify factors associated with disease recurrence in patients with high-grade cervical intra-epithelial neoplasia (CIN) undergoing large loop excision of the transformation zone (LLETZ). Study Design: A case-control study that included 103 patients. Patients were included in the study if they had a history of surgery for conization by LLETZ for the histopathological diagnosis of cervical intraepithelial neoplasia grades II and III (CIN II and CIN III). Follow-up exams were conducted every six months with Pap smear collection and colposcopic examination with biopsy, when necessary, for a minimum period of twelve months. Cure was defined as a normal follow-up examination within 24 months. During follow-up, relapse occurred when cytology and/or biopsy results showed that CIN had returned after 12 months, at which time a new cervical conization by LLETZ was performed.
This is an exploratory, open, prospective multi-centre study of VB10.16 immunotherapy in patients with high grade HPV16+ Cervical Intraepithelial Neoplasia (HSIL; CIN2/3). This study will recruit approximately 27-40 female patients with high grade cervical intraepithelial neoplasia (HSIL, CIN 2/3) at multiple sites in Europe.
This phase II trial studies how well accelerated partial breast irradiation (APBI) using high-dose rate (HDR) brachytherapy works in treating patients with breast cancer that has not spread beyond the breast or the axillary lymph nodes (early-stage) after surgery. Radiation therapy uses a type of energy to kill cancer cells and shrink tumors. Brachytherapy is a type of internal radiation therapy that provides radiation inside the breast to any remaining tumor cells next to the space where the tumor was removed, and is given over a shorter amount of time than standard radiation therapy. Giving accelerated partial breast irradiation (APBI) using high-dose rate (HDR) brachytherapy may reduce the overall time that radiation is delivered to the tumor cells.
A new mobile diagnostic and treatment unit is being developed by BCH to address the loss-to follow-up associated with the mobile screening program and demonstrate POC diagnosis by HRME. The mobile diagnostic and treatment unit will be equipped with the tools and infrastructure necessary to perform HRME, VIA, colposcopy, biopsy and treatment with cryotherapy. A team of a colposcopist, nurse, nursing assistant, and driver will staff the mobile diagnostic and treatment unit. The unit will travel to offer follow-up diagnostic and treatment services to women who have screened positive during a prior visit with the mobile screening unit. The mobile diagnostic and treatment unit will be constructed and maintained at BCH.
This research trial studies health-related symptom questionnaires in measuring quality of life in human immunodeficiency virus (HIV)-infected participants treated with or monitored for anal lesions. Collecting information and symptoms from patients diagnosed with anal lesions may help reduce the risk of anal cancer.
Loop electrosurgical excision procedure (LEEP) is the primary diagnostic and therapeutic procedure employed in women with high-grade intraepithelial neoplasia of the cervix. The procedure usually performed in the outpatient setting under local anesthesia. However, it could be associated with significant pain and anxiety. The aim of this study is to examine the effects of listening to music during the procedure in reducing pain and anxiety.
The proposed study seeks to compare the diagnostic performance of Human Papillomavirus (HPV) testing in self-collected samples via the Eve Medical self-collection system© (Eve) with standard physician-collected samples for the detection of cervical intraepithelial neoplasia grade 1 or worse (CIN1+) and cervical cancer among women referred for colposcopy. The performance of the Eve sample will also be compared with that of a second self-sample via a cobas® PCR Female swab. Approximately 1000 adult women with an abnormal Pap test at the level of an atypical squamous cells of undetermined significance or worse squamous or glandular abnormality (i.e., ASCUS+) or an abnormal co-test (ASCUS+ and HPV-positive) result will be recruited over a period of 12 months via colposcopy clinics located at the Jewish General Hospital, St-Mary's Hospital, and the McGill University Health Centers (Royal Victoria Hospital). Participating women will undergo three cervical or cervicovaginal sampling techniques: 1) self-sampling using the Eve Medical self-collection system©; 2) self-sampling using a cobas® PCR Female swab; and 3) physician-collected sampling. The participants will also fill in a questionnaire on their experience with the convenience and acceptability of the Eve system, relative to the other two sampling approaches. The decision as to which self-sample is to be collected first will be dependent on randomization HPV testing will be done using the cobas® 4800 HPV Test. The liquid medium of within the cobas® PCR CELL Collection Media with the provider collected sample and the cobas® PCR media with the two self-collected samples will be used to suspend the cellular material prior to HPV testing. We have made collaborative arrangements with Dr. Marcel Behr, Chief of the Department of Clinical Microbiology at the McGill University Health Centre for the HPV genotyping work. Histology-confirmed CIN1+ will form the study outcome or case definition. Sensitivity, specificity, and predictive values (along with their respective 95% confidence intervals) will be calculated for each sample type to evaluate the clinical performance of the various sampling techniques. We will use CIN1+ as definition of disease but analyses will also be performed for more stringent definitions, e.g. CIN2+ or CIN3/cancer.
This pilot research trial studies the effects of chemotherapy on intestinal bacteria/organisms (microbiota) in patients newly diagnosed with breast cancer. Change in intestinal microbiota may be associated with weight gain in patients treated with chemotherapy. Weight gain has been also associated with cancer recurrence. Examining the types and quantity of bacterial composition in the stool of breast cancer patients treated with chemotherapy may help determine whether body weight and composition are associated with changes in the intestinal microbiota and allow doctors to plan better treatment to prevent weight gain and possibly disease recurrence.
