Active clinical trials for "Neoplasms"

Currently, we conduct a prospective, randomized trial comparing the outcome of surgical excision with the outcome of curettage in nodular and superficial BCCs. Larger BCCs and micronodular or sclerosing BCCs are not included in the randomized study. They are mainly operated using three-dimensional histology (3D-histology, micrographic surgery). In this observational study we measure the cosmetic result and the recurrence rate of all BCCs not included in the randomized trial.

Comprehensive therapy of traditional Chinese medicine (CTTCM) could relieve risk of recurrence and metastasis for stage II & III colorectal cancer, the investigators take this clinical trial with retrospective-prospective cohort study based on previous studies by international multi-center way. If the study shows a positive result, a pragmatic randomized controlled study with prospective, multi-centre and large-sample design will be given continuously. The aim is to establish recommended programs suggested by CTTCM strategies under conventional Western medicine therapy (CWMT) for stage II & III colorectal cancer.

Stanford University Dermatology Clinics and Lucile Packard Children's Hospital are evaluating the use of the otoscope for the diagnosis of skin lesions. We are particularly looking for children and/or adults with nodules, cysts, tumors, or pilomatricomas. The study will take 15-30 minutes and we will use light to examine and take a picture of your skin lesion. There is no monetary compensation for participating in the study.

More recent studies have shown that the HBV-infected population has a greater risk of development of hepatocellular carcinoma. Nevertheless, there are still a significant number of people chronically infected by HBV who do not develop the complication. Hence, there exist biological markers that could be indicator for the disease-inducing and carcinogenic potential of the virus.

A Phase I-II Trial of Capecitabine (Xeloda), Oxaliplatin and Irinotecan in Combination with Bevacizumab in 1st Line Treatment of Metastatic Colorectal Cancer

The purpose of this study is to create new tests to identify biomarkers for ovarian cancer so that a screening test can be developed. For patients who have a diagnosis of ovarian Cancer, researchers will use blood samples before and after treatment to see if disease status can be determined by measuring the amount of biomarker.

The aim of the study is to find for one or more serum or tissue markers of molecular biology in head and neck cancer patients used for early diagnosis, predicting prognosis and being sensitive to chemotherapy and radiotherapy

Connective tissue growth factor (CTGF) is known to be a fibrogenic cytokine, it could be expressed in various fibrosis diseases. But, recent research showed that CTGF also be considered to be a tumor suppressive gene. The expression of CTGF protein is higher in normal Type I and II alveolar epithelial cells than metastatic tumor cells. CTGF appears to be a suppressor of lung tumor invasion and in metastasis and the decreased CTGF expression in tumor tissues was associated with advanced tumor stage, lymph node metastasis, early postoperative relapse and shorter patient survival. CTGF can be expressed in many human organs such as heart, brain, placenta, liver, muscle, kidney, peritoneal mesothelial cells and lung but did not known in the pleura. The CTGF protein is present in the peritoneal cavity and is increased during peritonitis. Considering pleural cavity comes from the same origin of mesenchyma with peritoneum, pericardium and fallopian tube, we aim to evaluate whether the CTGF expression increase in the pleurisy patients including the parapneumonic effusion and the TB pleurisy. The diagnosis of TB pleurisy depends on the effusion TB culture and pleural biopsy. Unfortunately the sensitivity of TB culture was only 20-30%. So most patients must receive invasive pleural biopsy. Adenosine deaminase(ADA) was developed as a screening test but should not be considered an alternative test to culture and biopsy. The sensitivity of ADA might vary from 32%-100% and the cutoff value also vary from 26 to 70 IU/L. We should develop a method to alternate the culture and biopsy . Therefore, our technologist Jao-Jia chu will develop the CTGF ELISA kit for this specific aim. If CGTF might increase expression in pleuritis but decrease in pleural metastasis, it might be a potential method help to differentiate lymphocytic pleural effusion between TB pleurisy and malignancy.

Comparison of single time point with dual time point PET imaging in the accuracy of diagnosing active lymphoma. Biopsy results or clinical/radiological progression will be used in conjunction with the PET data.
