Active clinical trials for "Neoplasms"

Clinical trials have demonstrated the efficacy of HPV-6/11/16/18 vaccination (Gardasil. Merck) 3 doses at day 1, month 2, and month 6 to lower the occurrence of high-grade cervical intraepithelial neoplasia than did those in the placebo group. The immunogenicity and efficacy of the HPV vaccine has not been proven in late stage chronic kidney disease (CKD) population. The cellular and humoral immune responsiveness of CKD population are impaired by the retention of uremic toxin due to glomerular filtration rate (GFR) reduction, the vaccination efficacy can be altered and the effective dose/schedule of the vaccine may need to be adjusted, mostly increase in CKD patients. This study aims to investigate the immunogenicity of quadrivalent HPV-6/11/16/18 vaccination (Gardasil. Merck) by current recommended dose/schedule in CKD stage IV-V patients and compare to non-CKD patients. Although a minimal peak anti-HPV response associated with protective efficacy has not been determined, the equivalent immune response in CKD and non-CKD patients if can be demonstrated by this study should be extrapolated to the CKD population. If less immune response results, the more intense dose/schedule of the vaccine should be further studied.

Sorafenib improves overall survival and progression free survival in advanced hepatocellular carcinoma. Wide interindividual pharmacokinetic variability was observed. Data from early phase trials in solid tumours showed trough sorafenib levels were associated with incidence of skin rash and hypertension. Rash, hypertension and higher trough levels were moderately predictive of progression free survival.The trough level of sorafenib may be predictive of survival and response in patients treated with sorafenib for advanced hepatocellular carcinoma.

The database and biobank establishment started in 1997 in our institute. However, the sample size was too small with respect to our clinical and fundamental scientific research's requirement. Thus the Chinese gynecological oncology study (GOS) group was established to create a large multicentre database and biobank of patients with gynecologic diseases.

Persistent replication of HBV (47-55%) is frequently found in patients with HCC, which in turn leads to deterioration of liver reserve. Moreover, a large proportion of HCC patients who underwent curative therapy died from progressive liver decompensation rather than recurrence of cancer. It had been proved that anti-viral therapy for hepatitis C virus (HCV)-related HCC patients could reduce the rate of tumor recurrence after surgical resection. This is a prospective study to evaluate the efficacy of ETV therapy in chronic hepatitis B patients after receiving RFA therapy for HCC.

The ACRIN 7151 trial will use medical records abstraction data from participants with extracolonic findings (ECFs) reported from the ACRIN 6664 National CT Colonography Trial to: 1) measure incidence of diagnostic imaging, hospitalization, and interventional procedures associated with ECFs reported on computed tomography colonography (CTC), delineated by type of ECF; 2) determine potential predictors of follow-up diagnostic imaging, hospitalization, and interventional procedures, delineated by type of ECF; and 3) evaluate the clinical/pathologic diagnoses associated with indeterminate but potentially significant ECFs. These data can be used to incorporate ECFs into existing models on the cost-effectiveness of CTC in colorectal cancer screening and can potentially be used to develop guidelines for the reporting and management of ECFs.

The purpose of this study is to evaluate clinical, dosimetrical, functional, biological and genetic factors in predicting chemo-radiotherapy induced lung and esophagus injury.

The purpose of this study is: To compare the long-term of survival and local/regional control between the two postoperative concurrent chemoradiotherapy regimens: capecitabine vs. oxaliplatin and capecitabine,for stage II and III rectal cancer To compare the toxicity profile between the two different concurrent chemoradiotherapy regimens.

RATIONALE: Studying samples of blood from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. PURPOSE: This study is looking at genetic susceptibility for cancer and interactions between genes and the environment in patients with colorectal cancer.

RATIONALE: Studying samples of tumor tissue and blood in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. It may also help doctors understand why low-grade gliomas develop in young patients and predict how they will respond to treatment. PURPOSE: This clinical trial is studying tumor tissue, blood samples, and family history in predicting tumor development and response to treatment in young patients with low-grade glioma.

RATIONALE: Collecting and storing stem cells to study in the laboratory may help doctors learn more about collecting stem cells from patients who have undergone treatment for Waldenstrom's macroglobulinemia. PURPOSE: This laboratory study is collecting stem cells from patients with Waldenstrom's macroglobulinemia.
