Active clinical trials for "Neoplasms"

The purpose of this study is to give patients who have had 4 or more prior lines of therapy for multiple myeloma access to VELCADE. The study is for patients who are not eligible for other clinical trials with VELCADE and for who VELCADE would otherwise not be available.

By testing the CTC number of new solitary pulmonary nodule patient, evaluating the correlation of CTC number and benign and malignant lung nodules auxiliary diagnosis, the correlation of CTC number and the size of lung nodules of the malignant patients, the correlation between the CTC number and subtypes of malignant lung nodules patients.The CTC and tumor markers will be detected before the patient received treatment. Tumor markers include Pro-GRP, NSE, CEA, CYFRA211, SCC.

This study has been designed in order to detect EGFR mutation abundance of tissue and concentration of plasma from Advanced Non-small Cell Lung Cancer during treatment with Tyrosine Kinase Inhibitor (TKI) .Through this experiment the investigators aim to evaluate the feasibility of plasma EGFR detection and evaluate the correlation of EGFR mutations and prognosis.

Colorectal cancers (CRC) are the third most common human malignancy, and are also the leading cause of cancer related deaths worldwide. Early detection of premalignant lesions such as adenomatous polyps has decreased the risk of CRCs; however, cases which are initially undetected and progress to advanced CRC with distant metastasis are still unfortunately incurable. The development of CRC is a complex and heterogeneous process arising from an interaction between multiple etiological factors, including genetic factors and environmental factors such as diet and lifestyle. The challenges are to understand the molecular basis of individual susceptibility to colorectal cancer and to determine factors that initiate the development of the tumor, drive its progression, and determine its responsiveness or resistance to antitumor agents. Next generation sequencing(NGS)-driven genomic studies are already reporting novel features of cancer genomes beyond the traditional mutational categories. Recent advance in sequencing technology has enabled comprehensive profiling of genetic alterations in CRC.These methods are facilitating an increase in the efficiency and resolution of detection of each of the principal types of somatic cancer genome alterations, including nucleotide substitutions, small insertions and deletions, copy number alterations, chromosomal rearrangements,DNA methylation sequencing such as bisulfite-sequencing and microbial infections. Besides the microsatellite instability (MSI), some researchers reported novel mitochondrial mutations in the cancer genomes. NGS technology will help the investigators for understanding of entire CRC genomes and the obtained knowledge will lead to a better diagnosis and personalized targeted therapeutics for CRC management

The purpose of this prospective study is to evaluate whether DNA methylation can be applied in cervical cancer screening.

To evaluate the clinical significance of cell free DNA (cfDNA) and circulating tumor cells (CTCs) in real-time monitoring the therapeutic response during HER2-targeted therapy in histologically confirmed HER2 positive advanced/metastatic gastric cancer.

The primary objective is to determine the sensitivity and specificity of the HPV Integration-based cervical screening for detection of high-grade cervical intraepithelial neoplasia (CIN), using colposcopic inspection as the reference method. Lesions will be confirmed as malignant or CIN by colposcopic inspection and histopathologic examination.

The primary objective of this trial is to determine the impact of the FOLFOX regimen on quality of life and the incidence of chemotherapy induced neurotoxicity.

To explore the significance of Solute Carrier Family 1 Member 5 (SLC1A5) in the occurrence of esophageal cancer, by comparing the expression of SLC1A5 between esophageal cancer tissues and adjacent tissues.

This study will explore the potential value in proper therapeutic decision and clinical outcome prediction by using integrated MR-PET system and advanced MR techniques in patients with colorectal cancer.
