Active clinical trials for "Neoplasms"

The aim of this study is to evaluate the hepatic perfusion computer tomography and dual energy computer tomography in the assessment of tumor characterization of Hepatocellular carcinoma in patients with resectable Hepatocellular carcinoma by comparing the quantitative parameters computer tomography obtained with the pathological data of the surgical specimens.

Colorectal cancer (CRC) is the third most common cancer in men and the second in women worldwide, with 1.65 million new cases and almost 835,000 deaths in 2015. CRC is still a major cause of mortality associated with cancer, although the wide spread of the screening program has led to a reduction in the mortality rate compared to the last decades. CRCs derive from precancerous lesions that may be polypoid or non-polypoid according to the Paris classification. Thus, resection in an early stage could led to a CRC mortality reduction. Laterally spreading tumors (LST) are non-polypoid lesions of at least 1 cm in diameter that have lateral growth rather than upward or downward growth. The prevalence of LSTs ranges from 1 to 6% of all colorectal lesions. LSTs can be divided into two groups: granular LSTs, which include homogeneous and granular mixed forms and non-granular (NG) LSTs, which include pseudo-depressed and flat-elevated forms. Histologically, 90% of LSTs are adenomas and having a low incidence of invasive neoplasia, these lesions can be removed endoscopically. However, as evidenced by a recent meta-analysis published by Bogie Roel MM et al on Endoscopy, the type of LST and the distal or proximal colonic localization could represent predictors of submucosal invasion and could simplify the therapeutic decision for the removal of these lesions. GM-LSTs and pseudo-depressed NG-LSTs predominantly localize in the distal portion of the colon and have a submucosal invasion rate of 10,5% and 31,6% respectively. LSTs can be removed both through endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD). The main limitation of EMR is that large lesions require a piecemeal approach, resulting in a non-optimal histological evaluation and a high risk of recurrence. ESD instead allows a higher rate of en bloc resections, thus resulting more curative and reducing the risk of having partial and incomplete resections, which can lead to disease recurrence/non curative resection. LST-GM are characterized by the presence of a granular appearance with a main nodule and represent approximately 1/4 of the LSTs. There are no guidelines indicating the proper resective technique of these lesions. The European Society of Gastrointestinal Endoscopy (ESGE) suggests to consider ESD for the removal of colorectal lesions that are > 20 mm in size, with a depressed and irregular morphology or a non-granular surface pattern, as these lesions have a high probability of having a limited submucosal invasion. Moreover ESD can be used to treat lesions that cannot be completely removed with standard polypectomy or EMR. The investigators propose to perform a multicenter retrospective observational study to define the percentage of cancer in patients with GM-LSTs treated with endoscopic resection in order to evaluate the correlation between pre-resection and post-resection characteristics, defining the best therapeutic approach (en bloc or piecemeal) and avoiding incomplete endoscopic resections or unnecessary surgical procedures.

A total of 160 cases of nasopharyngeal carcinoma patients who met the inclusion criteria were randomly assigned to two groups. The experimental group was given massage of maxillofacial and oral cavity plus routine oral care and functional exercise. The control group was given routine oral care and functional exercise. Analyze the difference of incidence of severe acute radioactive oral mucositis in these two groups.

Cervical conization using the loop electrosurgical excision procedure (LEEP) is the standard treatment for patients with high-grade cervical intraepithelial neoplasia. Several studies have shown that excising a central cone reduces the rate of positive endocervical margins. The purpose of this study is to identify clinicopathological factors associated with residual disease in the central cone and to develop a predictive model to better determine which patients may require this additional procedure.

Gastric cancer is most frequent after the fifth decade of life. Surgical risk is higher in aged population because of general health condition may affect the postoperative result. Aim of the study was to identify risk factors for post-operative mortality in octogenarian patients who underwent surgery for gastric cancer.

The goal of this project is to investigate the extent and role of mesothelial - mesenchymal transition (MMT) and cancer associated fibroblasts (CAFs) in the pathogenesis of colorectal peritoneal carcinomatosis (PC).

The objective of this study is to evaluate the performances of the Six-Minute Stepper Test (6MST) and Sit To Stand test (STST) to predict post-operative complications after minimally invasive lung cancer resection.

Central nervous system involvement at diagnosis remains an obstacle to a long-term cure of patients affected by acute lymphoblastic leukemia. The investigators have previously reported that flow cytometry (FCM) is better than conventional cytology (CC) in demonstrating the presence of leukemic cells in the patients'(pts) cerebrospinal fluid (CSF), especially in samples with low cell counts. In the framework of the national Campus ALL program aimed at improving the management of adult ALL patients in the context of the GIMEMA protocols, in the present study the investigators retrospectively evaluated the incidence of occult CNS positivity and its impact on outcome in 241 adult pts with newly diagnosed ALL from 13 centers.

Primary Objective The objective is to determine the feasibility and agreement of remote evaluation of resting heart rate and HRV using the commercially available WHOOP® wrist monitor, compared to in-office measurements using AtCor Medical SphygmoCor HRV Software, in a cohort of 40 St. Jude Life Study participants with a history of mantle radiation for management of Hodgkin lymphoma. Elucidating the mechanisms that contribute to adverse cardiovascular outcomes and reduced quality of life among the growing population of childhood cancer survivors is paramount. Cancer, certain cancer drugs, radiation therapy, cancer-associated lifestyle disturbances, and cancer-independent comorbidities combine to predispose cancer survivors to autonomic dysfunction (AD). Reduced heart rate variability (HRV) has been described in various cancer cohorts. Furthermore, these markers of AD have been implicated in adverse outcomes in oncology patients, including increased mortality, exercise limitation, and fatigue. However, data are largely derived from small studies with methodological limitations, and the contribution of AD to overall morbidity and mortality in cancer survivors is not well understood. The objective is to determine the feasibility and agreement of remote evaluation of resting heart rate and HRV using the commercially available WHOOP® wrist monitor, compared to in-office measurements using AtCor Medical SphygmoCor HRV Software, in a cohort of 40 St. Jude Life Study participants with a history of mantle radiation for management of Hodgkin lymphoma.

"The patient's journey" is an interview based study assessing the patients' experience from the first symptoms to a final diagnosis focusing on patients with small intestinal neuroendocrine tumors.
