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.
Upper gastrointestinal subepithelial tumors are frequently encountered during esophagogastroduodenoscopy. Treatment plans for subepithelial tumors are determined by algorithms based on endoscopic ultrasonography images. However, endoscopic ultrasonography alone may not be able to diagnose and evaluate upper gastrointestinal SETs with sufficient accuracy. Adequate tissue samples are required to increase the diagnostic accuracy of subepithelial tumors. Deep biopsy is method that normal mucosa was dissected using enodsocpi submucosal dissection technique and multiple endoscopic biopsies were performed. The investigators will perform deep biopsy in subepithelial tumor.
Laparoscopic complete mesocolic excision is a concept that using laparoscopic surgery technique to perform a resection for colon cancer. Besides, the segment of the colon containing the tumor, the resection area should include an intact mesocolon as an envelope to encase the possible route for metastasis. The routes include blood vessels, lymphatic drain and etc. Such hypothesis predicts better histopathological and higher oncological results which turns into better survival rate and better quality of life.
By determining the correlation of a Crossed Leg Sign with signifcant pathology, a clinician would then be able to use this correlation to risk stratify his/her patients for significant pathology.
