Active clinical trials for "Neoplasms"

The peritoneum is the second most common site of recurrence in patients with colorectal cancer. Cytoreductive surgery with hyperthermic intraperitoneal chemotherapy improve the prognosis of these patients and incorporates surgical removal of all visible disease followed by chemical destruction of microscopic disease through chemoperfusion. The most validated predictors of outcome are preoperative tumor burden measured in terms of the peritoneal carcinomatosis index (PCI) and completeness of cytoreduction (CC score). Diagnostic laparoscopy prior to resection is widely used in hepatopancreaticobiliary and colorectal cancer and has been shown to be effective in excluding unnecessary laparotomy associated with higher morbidity.

The main goal of this study is to employ a novel proteomic approach to identify predictive tumor biomarkers that will increase the efficacy of insulin-like growth factor (IGF1R) targeted therapy in epithelial ovarian cancer. It is expected that these predictive biomarkers will be applied to increase the response rate in selected groups of patients.

The purpose of this study is to define the role of total body composition in the guidance of nutritional support and treatment monitoring in head and neck patients. Furthermore, the second aim of this study is to compare the clinical performance of dual energy X-ray absorptiometry as compared to CT in evaluating total body composition of patients.

The investigators propose a non-invasive prognostic tool for TKIs resistance in patients with stage IV EGFR-mutant non-small cell lung cancer (NSCLC) by computed tomography phenotypic features, which can be conveniently translated to facilitate the pre-therapy individualized management of EGFR TKIs in this disease.

The purpose of this study is to evaluate the effect of ALDH2 mutation in radiation associating dermatitis or mucositis in head and neck cancer patients who accept chemoradiation therapy

CLL is a disease of the elderly, identifying effective therapies with better toxicity profiles is thus a high priority, and targeted therapies may allow attainment of this goal.

This is a prospective observational cohort study of haploidentical transplantation with post-transplant cyclophosphamide for acute leukemias using reduced intensity conditioning for acute myeloid leukemia (AML) and myeloablative conditioning for acute lymphoblastic leukemia (ALL).

The aim of the study is to measure tumoral angiogenesis modifications by RGD-K5 PET/CT before and after 2 cycles of chemotherapy in patients with lymphoma and a large tumoral mass

The purpose of this study is to observe whether dopamine agonists can be safely withdrawn after the tumor volume and prolactin level of invasive prolactinomas involving the cavernous sinus have been effectively controlled through pharmacological treatment.

Esophageal carcinoma is a lethal disease, causing more than 400,000 deaths annually worldwide. Primary surgery results in microscopically positive resection margins (R1) in 25% patients, and the 5-year overall survival(OS) for such patients rarely exceeds 40%. Concurrent chemoradiation followed by surgery results in better survival than single-modality treatments, and thus National Comprehensive Cancer Network(NCCN) recommends concurrent chemoradiation as preoperative or definitive treatment for patients with stage II or III esophageal cancer. However, neoadjuvant chemoradiation may not be effective in some subgroup of these patients, and its toxicity can increase perioperative mortality and delay or preclude surgery. The ability to distinguish tumors that will respond or not respond to such therapy remains an urgent priority. Diffusion-weighted magnetic resonance imaging(DW-MRI) is based on the extent of mobility of water protons, as quantified by the apparent diffusion coefficient (ADC). The ADC is a measure of the extent of free diffusion of water molecules within tissues, which is mainly influenced by cell organization, size, and density. Cell death leads to a loss of cell membrane integrity and density and leads to increases in ADC values. The ADC has emerged as a potential biomarker of response to cancer therapy. However, no one has published findings regarding the potential correlation between changes in ADC and response of esophageal cancer to chemoradiation. Clarifying the potential predictive value of DW-MRI for predicting response to such therapy is important for the delivery of appropriately tailored treatment. Investigators hypothesized that DW-MRI can predict the success (or failure) of neoadjuvant chemoradiation in esophageal squamous cell carcinoma（ESCC）, hence identify patients at high risk of treatment failure from such therapy. Investigators will test this hypothesis with two specific aims: (1) assess the ability of ADC to predict pathologic response to treatment; and (2) assess the ability of ADC to predict disease-free survival and overall survival.
