Active clinical trials for "Carcinoma in Situ"

This is a prospective registry trial to determine the outcomes of single port robot-assisted nipple sparing mastectomy (SPrNSM) utilitzing the SP da Vinci surgical system.

The purpose of this study is to finalize development of a questionnaire that measures health-related symptoms and concerns for persons diagnosed with, and either treated or monitored for, anal pre-cancer lesions.

The objective of this study is to determine whether we can use minimally invasive techniques to gain access to exfoliated ductal epithelial cells for whole genome sequencing. To examine women with nipple aspiration, ductoscopy and ductal lavage and collect exfoliated cells from two ducts per woman. To collect a blood sample at the time of the examination in order to obtain the woman's baseline genomic sequence. De-identified samples will then have DNA and RNA extracted and whole genome sequencing and transcriptome analysis performed by Covance and Illumina. Comparisons will be made within a breast (two ducts) and between the duct and blood as well as between women.

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.

Although cervical cancer is a preventable cancer, every year more than one-quarter of a million women die worldwide from this disease. Internationally and nationally, cervical cancer is a disease that affects predominantly women who are poor and who live in resource poor settings. With the device the investigators are developing, known as the Multispectral Digital Colposcope with probe, our goal is to make detection of precancerous cervical lesions easier for the patient and for her provider. For the patient, our goal is to reduce the number of clinical visits needed to obtain a diagnosis and treatment and consequently to reduce the resulting fear and anxiety which usually accompanies an abnormal Pap smear. For the provider and the health care system, our goal is to obtain a more accurate diagnosis than the currently available diagnostic methods.

The primary objective of this study is to compare the diagnostic accuracy of Digital Breast Tomosynthesis (DBT) versus that of Contrast Enhanced Magnetic Resonance Imaging (CEMRI) in determining the size of breast cancer preoperatively. Secondary objectives include: Comparing the operating characteristics of each combined imaging protocol with respect to the reference standard, i.e. histopathologic assessment, of additional non-index lesions. Comparison of re-excision rates based on estimated disease extent from adjunctive CEMRI vs. adjunctive DBT. Evaluation of patient satisfaction with regard to the adjunctive modality (DBT vs. CEMRI).

Oral epithelial dysplasia (OED) is one of the common precancerous lesions among Chinese adults. Biomarker is not available for detection of malignant potential of OED till now. p16 is an important tumor suppressor gene, which is inactivated frequently by methylation of CpG island in early stage of carcinogenesis. The present cohort study is to investigate whether p16 methylation is correlated with malignant transformation of OED.

Introduction Cervical intraepithelial neoplasia CIN1 (low grade), CIN2 (moderate grade), CIN3 (severe grade) defines cervical precancer lesions derived from the squamous epithelial cell line. CIN2, represents a heterogenic phenotype expression of both CIN1-like and CIN3-like evolving lesions with different risk of progression. The CIN2 diagnosis has low reproducibility, and current diagnostic tools do not allow for risk-stratification of CIN2. Risk-profiling is important, to enable targeted management of women with CIN2 at first incidence (surgery or active surveillance) and to avoid risk of over- or undertreatment. Preliminary studies show, that the novel tissue biomarker HPV E4 has potential to discriminate CIN1-like (HPV E4 positive) from CIN3-like (HPV E4 negative) evolving CIN2 lesions, suggesting that the biomarker could be vauable for risk-stratification of CIN2. Aim To examine the potential of the HPV E4 biomarker in predicting risk of CIN2 evolvement. Materials and Methods Design: Historical cohort study. Study population: N=500 women, 23-40 years of age with a record of incidental CIN2 diagnosis between [2000-2010] in the Danish Pathology Data Bank at Aarhus University Hospital, Region of Central Denmark. All women are defined as managed by active surveillance (i.e. no surgical treatment within 4 months after first CIN2 diagnosis). Exposure: HPV E4 positive vs HPV E4 negative intraepithelial reaction. Outcome: Regression (normal, CIN1) vs non-regression (CIN2, CIN3, cervical cancer). Statistical model: Linear regression model (RR (95%CI)). Perspectives: HPV E4 may act as significant predictor for CIN2 evolvement, and reliable marker for risk-assessment of CIN2. This will be valuable in the clinical management of women with CIN2, enabling to discriminate women, who would most likely regress and could be manged by active surveillance vs women in risk of progression or persistence, who could benefit of immediate surgical treatment.

This study is designed to evaluate the feasibility and safety of partial breast irradiation for low risk DCIS after breast-conserving surgery.

RATIONALE: Gathering information about genetic changes in patients with lobular carcinoma in situ of the breast may help doctors learn more about the disease and find better methods of treatment. PURPOSE: This clinical trial is studying the genetics of women with lobular carcinoma in situ of the breast.
