Active clinical trials for "Carcinoma"

Hepatocellular carcinoma (HCC) is the most common primary liver cancer and is the third leading cause of cancer that related death in the worldwide. Although, current most of doctors and laboratorians of HCC diagnoses bases are medical imaging such ultrasound, MRI, CT-scan and laboratory analyses tests for serum tumor markers such as alpha-fetoprotein (AFP) which characterized by very low of sensitivity in the detection of HCC. Last two decades, scientists was focused researches of small molecules called MicroRNAs which are produced by human cells and can be released in the blood. MicroRNAs are class of (20 - 25 nucleotide in length) non-coding RNAs, and its emerging non-invasive diagnostic biomarker for cancer diagnosing, screening, monitoring treatment and to predict prognosis. A number of studies exposed an abnormal expression of human serum MicroRNAs in many tumors such as liver, pancreatic and colorectal carcinoma. Recently, MicroRNAs have a role in the development of HCC, but still it is unknown if these small molecules will be used as biomarker for diagnosis and survival of HCC. The aim of this study is to establish MicroRNAs as biomarkers for diagnostic tool of HCC patients and to compare to circulating levels of MicroRNAs in chronic liver diseases patients and health volunteers and those HCC patients and To determine the clinical utility of MicroRNAs as a diagnostic maker of hepatocellular carcinoma comparing with alpha fetoprotein the current marker of (HCC).

To evaluate efficacy and safety profile of DC bead® TACE in patients with hepatocellular carcinoma in Taiwan.

The goal of this study is to determine the optical spectroscopy characteristics of tumor in patients with head and neck squamous cell carcinoma (HNSCC). HNSCC constitutes over 90% of all head and neck cancers. These spectroscopy measurements will be compared with pathological diagnosis of tissue biopsies from the same site. These readings will be performed in the operating room during routine endoscopy with biopsy and tumor mapping of patients who have a suspected squamous cell carcinoma of the head and/or neck. Furthermore, a built in pressure sensor will be used to compare biopsy sites with their benign counterparts. If successful, the optical measurements could be used to survey for and delineate the extent of malignancies in a noninvasive manner. This would be especially helpful for clinic visits where suspicious lesions are seen and would otherwise require biopsy for diagnosis. Immediate benefits would include patients with unknown primaries in which numerous directed biopsies are obtained from multiple head and neck sites.

Basal cell carcinoma (BCC) is the most frequent neoplasia worldwide. There are more than 30 histopathologic subtypes, however the nodular subtype is the most common. Pigmented varieties are common in darker skin types, therefore in our country. Previous studies have shown an increase number and size of melanocytes. Melanogenesis were increased at the expense of hyperfunctioning melanocytes as well. The aim of the study was to describe the characteristics of melanocytes in pigmented and non-pigmented variants of basal cell carcinoma.

The primary purpose of this study is to compare the positive rate between the cell-free DNA and cytological examination of cerebrospinal fluid in Advanced lung cancer with leptomeningeal metastases.

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.

This study is a prospective clinical study using DCE-MRI, DWI and MRS in 3T scanner to evaluate tumors in patients with unresectable HCC after TACE. A total of 100 subjects will be recruited. MRI will be performed before TACE (day 0), day 14, and day 28 to assess the tumor responses. After day 28, all subjects will receive standard clinical care and be follow-up for 1 year. The imaging parameters will be compared among each MRI and correlate with patients' outcome. The investigators hypothesis that it might be helpful to combine DCE-MRI, DWI, and MRS for assessment of tumor response after TACE and predict patients' prognosis.

Bladder urothelial carcinoma (UC) is a common malignancy and the incidence is increasing by years in Taiwan. Chemoresistance was inevitable in treatment of metastatic disease and lead to the ominous outcomes. To develop novel therapeutic strategies to overcome chemoresistance is imperative. Cancer cells uptake glucose at higher rates than normal tissue but use most of glucose for glycolysis even under normoxia condition, which is known as the Warburg effect. Pyruvate kinase (PK) catalyzes the last step in the process of glycolysis, and one of it isoform--PKM2 has been reported to be associated with tumor progression and some specific tissues and promotes the Warburg effect in cancer cells.

Urothelial carcinoma (UC) is the most common cancer of urinary tract. Patients with metastatic UC are usually treated with systemic chemotherapy. There still existed 30% to 50% of advanced UC not responsive to cisplatin-based chemotherapy; the prognosis for patients with metastatic UC remains poor.

The aim was to investigate the efficacy of radiofrequency ablation (RFA) with a multiple-electrode switching system (MESS) in the treatment of early hepatocellular carcinoma (HCC) and to evaluate the patterns and risk factors of intrahepatic recurrence of HCC after RFA.
