Active clinical trials for "Neoplasms"

The study aims to assess treatment patterns and outcomes in advanced RCC patients in real world clinical practices across various real world databases. Four databases will be evaluated

To determine the optimal EGFR TKIs treatment strategies for lung adenocarcinoma harboring EGFR exon 19 deletion variants

The aim of the present project is to evaluate the frequency of distant metastases and clinically relevant relapse and mortality, respectively, of aNEN (Neuroendocrine Neoplasms of the Appendix) measuring 1 - 2 cm. The investigators hypothesize that the mortality rate of aNET (Neuroendocrine Tumors of the Appendix) measuring 1 - 2cm is less than 1%. Furthermore, the investigators hypothesize that regional lymph node metastases of aNET measuring 1 - 2 cm are clinically not relevant and are not associated with reduced survival. The investigators therefore hypothesize that oncological right-sided hemicolectomy has no impact on long-term survival after complete resection of aNET measuring 1 - 2 cm and that the malignant potential quo ad vitam of these tumors is lower than the risk of oncological hemicolectomy.

Controlling hypothermia is essential in anesthesia to limit postoperative complications. Temperature monitoring is therefore essential. However, the reliability of esophageal temperature during open chest lung surgery is discussed and not accurately assessed in the literature.

Patients aged > 80 years represent an increasing proportion of colon cancer diagnoses. It is important to have relevant and trustable data concerning elderly colorectal cancer patients surgery and postoperative morbidity, functional ability, life quality and survival numbers. With possibly compromised health status and functional decline the benefits of surgical management and outcomes can diminish life quality and overall survival. With proper patients selection, preoperative health evaluation and thus patient information, colorectal cancer surgery can be performed with lower morbidity and mortality rates with comparative survival numbers. The aim of this prospectively collected, observational study is to acquire data from colorectal cancer surgery in aged over 80 years and perform statistical analysis of the preoperative risk factors affecting postoperative morbidity, functional recovery, mortality and overall survival.

There is no consensus on what type of function-preserving gastrectomy can provide the best patient quality of life (QOL). This study aims to evaluate the incidence of dumping syndrome after vagus nerve-preserving distal gastrectomy (VPNDG).

The oropharynx is a complex anatomical structure necessary for nasal breathing, swallowing and phonation. The removal of oropharyngeal cancers can lead to sequelae, particularly in the case of resections affecting the soft palate. The main sequelae are represented by rhinolalia and swallowing disorders with nasal regurgitation. The treatment of oropharyngeal tumors is based on primary surgery or radiotherapy, but tumors of the soft palate are often treated by radiotherapy or radio-chemotherapy first. Surgery is often kept for relapses, because it is considered to lead to important sequelae. However, chemoradiotherapy of the oropharynx is also responsible for acute toxicities, and late sequelae can be frequent and important. Recent publications tend to show that primary surgery would give better survival rates compared to radiotherapy, particularly in advanced stages, including viro-induced cancers. In addition, primary surgery can reduce the dose of radiation delivered to the oropharynx and thus reduce its long-term toxicity. It is currently possible to reconstruct a loss of substance after surgery of oropharyngeal cancers, including the soft palate by using free flaps, limiting the postoperative sequelae usually observed without reconstruction. There is little data on reconstructions of the soft palate, their sequelae and their impact on the quality of life.

Retrospective review of 5-year long term outcomes of superselective intra-arterial chemotherapy treatment in retinoblastoma in a single institute. The treatment outcomes, globe salvage rates and complications of superselective intra-arterial chemotherapy both for treating naive patients (primary treatment group) and for patients who received systemic chemotherapy previously (secondary treatment group) were evaluated.

In recent years, with the continuous development of artificial intelligence, automatic polyp detection systems have shown its potential in increasing the colorectal lesions. Yet, whether this system can increase polyp and adenoma detection rates in the real clinical setting is still need to be proved. The primary objective of this study is to examine whether a combination of colonoscopy and a deep learning-based automatic polyp detection system is a feasible way to increase adenoma detection rate compared to standard colonoscopy.

The aim of this study is to quantify inter-observer variability in delineating pancreatic neuroendocrine neoplasm (PanNEN) on Computerized Tomography (CT) images and its impact on radiomic features (RF), subsequently to this determination, to use CT texture analysis to predict, histological characteristics of PanNEN on CT scans.
