Filter by:This study is designed to evaluate the instrument precision of the device for its proposed intended use in sub-studies: intra-system and inter-system. The precision within a system will be evaluated on three systems by three pathologists at one site. Specific features will be selected on glass slides, which will then be scanned. On the whole slide images field of views will be created including the features. In the reading phase three pathologists will read the field of views and record which features they observe.
This study aims to test the hypothesis that the diagnosis for histological type, histological grade, LAUREN type, HER-2 expression, MSI/dMMR status, and EBV status in gastric cancer is at least as reliable when performed on endoscopic biopsy specimens as on surgical resection specimens.
Little is known about the correlation between ultrasound characteristics (conventional, elastography and contrast enhanced ultrasound (CEUS) )and pathological prognostic factors in breast cancer. The aim of this study was to explore the correlation between ultrasound characteristics and pathological prognostic factors using radiomics.
Chronic Venous Disease (CVD) has a high prevalence in the general population of the western world. Varicose veins are the main signs of this disease that are characterized by important pathological vessel wall changes. There are also several symptoms that affect the quality of life of affected patients. The aim of this study is to correlate the main histopathological abnormalities with the type and the intensity of the symptoms.
To set up a Cooperative Network by enrolling 5000 patients with Adenomyosis(AM) from multiple centers.Based on the Network platform and Database,the investigators try to explore the diagnostic strategies for AM and carry out epidemiological survey on the semeiology of AM.In addiction，the investigators expect to conduct research on the effect and the follow-up fertility outcomes of different medical or surgical treatment, the etiology of AM and endometriosis,the perspective investigation of the malignant transformation of AM ;the high-risk factors of AM,and finally propel the formation of Expert Consensus and Clinical Guidelines about AM which suitable to chinese conditions.
The effect of preoperative glycemic control measured by HbA1c on prostate cancer (PCa) outcome remains controversial. Thus, the investigators aim to examine the association of preoperative glycemic control with oncologic outcomes after radical prostatectomy (RP). The investigators will prospectively collect the relevant data including preoperative HbA1c in 264 patients of PCa patients undergoing RP. The associations between clinical variables and risk of adverse pathological features and disease recurrence will be tested using a multivariate logistic regression and multiple Cox-proportional hazards model, respectively.
The effect of preoperative glycemic control measured by HbA1c on renal cell carcinoma (RCC) outcome remains controversial. Thus, the investigators aim to examine the association of preoperative glycemic control with oncologic outcomes after radical or partial nephrectomy. The investigators will prospectively collect the relevant data including preoperative HbA1c in 238 patients of RCC patients undergoing nephrectomy. The associations between clinical variables and risk of adverse pathological features and disease recurrence will be tested using a multivariate logistic regression and multiple Cox-proportional hazards model, respectively.
Over the past decade the paradigm of care in oncology has evolved with the advent of personalized medicine. Yet, despite this exciting prospect, there are currently only a few disease subtypes where therapeutic approaches with proven benefit exist such as EGFR targeted therapies in EGFR-mutant lung tumours. With the increasing number of novel molecularly targeted agents available, the importance of building our understanding of cancer biology is critical. Challenges to implement personalized medicine include the limitations of molecular testing, tumour heterogeneity and molecular evolution, costs, and the quality and morbidity associated with tumour biopsies. Sequential biopsies are essential to better understand biological markers of response and resistance, and identify predictive or prognostic markers. Despite the scientific rationale for biopsies, incorporating them into practice can be challenging, as in many cases there is no direct advantage to the patient. This project aims to understand the effect of research biopsies on the patient. The Investigator hypothesize by learning more and gaining a better appreciation of the impact on the patient, Investigators will increase the likelihood of achieving serial biopsies. The ability to obtain serial biopsies is dependent on the patient's experience. To understand the clonal progression of cancer and validate predictive and prognostic markers of response, studies now target biopsies both at enrollment and at progression. As Investigators strive to achieve this, improving our understanding of the patient's experience will help us identify factors that positively and negatively impact on patient participation and influence the probability of successfully obtaining sequential samples.
