Active clinical trials for "Neoplasms"

This was a retrospective case-control study designed and conducted under the approval of the ethic committee of Tehran University of Medical Sciences. All patients with gastric cancer referring to Cancer Institute, Tehran University of Medical Sciences, Tehran, Iran, during February 25th and December 25th 2020, were enrolled to the study.

Anesthesia management of pheochromocytoma excision surgery is associated with severe hemodynamic fluctuations.The objective of this study was to compare the hypertensive episodes requiring sodium nitroprusside administration between the group treated with magnesium-dexmedetomidine and conventional group in pheochromocytoma.

Shear wave electrography score allows stratification of HCC risk in a noninvasive and reliable way and can guide the surveillance strategy for HCC in patients with CLD

Extraction of laboratory data from blood tests prior to surgical and chemotherapy and other histological, clinical and instrumental data related to the patient's history from the digitized medical Digitized medical records and analysis of the same. The medical records of 1000 patients from January 1, 2000, until December 31, 2020

Remimazolam is a novel drug approved for induction and maintenance of general anesthesia. This study aims to check the appropriate dose and patient response by administering remimazolam and remifentanil in surgery that does not require a neuromuscular blocking agents.

Imaging findings (including CT and MRI images) of both well-differentiated G3 PNET and poorly differentiated PNET were studied; The CT imaging findings of G3 stage PNET and pancreatic cancer were compared to establish a Logistic regression diagnostic model, and the survival analysis of the two was compared. Cox regression was used to study the risk factors for survival prognosis of well-differentiated and poorly differentiated PNET based on CT image features

Exploit CT (plain scan), enhanced CT and fMRI based radiomic biomarkers, explore their correlation with the prognostic molecular markers of spinal GCTB(p53/vegf/rank/rankl…), and help accurate diagnosis of GCTB. Exploring a new method of preoperative risk stratification for spinal GCTB, and establishing radiomic model combined with clinical features. Exploring the GCTB biological behavior prediction model and the prognosis prediction of GCTB.

Clinical data of 185 consecutive patients receiving resective operation with a pathological diagnosis of craniopharyngioma in our hospital between January 2013 and February 2021 were collected. Among these patients, 18 of them were recognized as craniopharyngioma with tumoral hemorrhage during the operation.

Frailty is common in patients with gastric cancer undergoing surgical treatment. Preoperative frailty can lead to many adverse outcomes in patients after surgery. This study aims to comprehensively and systematically analyze the influencing factors of preoperative frailty in patients with gastric cancer based on the health ecology theory , to change some critical variable factors in the future, improving the overall prognosis of patients.

Main limitations in Glioma studies are due to the wide heterogeneity and genetic instability of the tumor and to the fact that the molecular informations are static, i.e. obtained on the tumor at its onset. Instead, spontaneous or therapy-induced variations are difficult to evaluate and they would need further sampling of the tumor throughout the clinical history. Currently these data are more and more routinely used not only for diagnostics but also in the clinical management of the patient. Furthermore, microenvironment study is becoming increasingly important. It is also important correlate morpho-functional pathway and brain Magnetic Resonance. Therefore, the main goal of the study is to correlate the data obtained with morphological (site, signal intensity, margins, behavior after contrast medium infusion, mismatch between T2 and FLAIR sequences) and non-morphological MR imaging through a radiomic approach and Diffusion and Perfusion study, with molecular data relating to the IDH mutation, MGMT gene promoter methylation, 1p/19q co-deletion and EGFRvIII expression. Furthermore, it is proposed to carry out a correlation between the radiological data and the mutations found in the NGS panel.
