Active clinical trials for "Adenocarcinoma"

SUMMARY Rationale: Diagnostic laparoscopy (DL) and response assessment after neoadjuvant chemotherapy with computed tomography (CT) are two diagnostic modalities used to assess metastatic spread in gastric cancer patients. It is still unclear in what proportion of patients clinically relevant metastases or other significant findings (e.g. contra-indications of surgery) are detected that impact on the treatment. Objective: To determine the clinical value of diagnostic laparoscopy and computed tomography response assessment after neoadjuvant chemotherapy in patients with gastric and esophagogastric junction adenocarcinoma. Study design: Multicentre retrospective cohort study. Study population: All Patients with gastric and gastro-oesophageal adenocarcinoma who underwent clinical staging and were discussed at multidisciplinary team meetings (MDT) between January 2016 and December 2018. Intervention (if applicable): Not applicable. Main study parameters/endpoints: The main study parameter is the proportion (%) of patients who do not proceed with treatment as planned after a DL and CT response assessment (i.e. the proportion of patients in which metastasized disease or other contra-indications for surgery is found). Nature and extent of the burden and risks associated with participation, benefit and group relatedness: Since this is an observational study, no burden or risks are associated with participation.

This study is one of Eastern Cooperative Thoracic Oncology Projects (ECTOP-1008). It aims to evaluate the correlation between radiological diagnosis based on HRCT and pathological invasiveness.Investigators observe the radiological features and the correlation with the postoperative pathological findings.

The purpose of this study is to collect blood samples and study cancer cells found in these blood samples from patients with pancreatic cancer. Prior research has discovered that tumor cells can be collected from the blood of patients with pancreatic and other cancers. The physicians have developed techniques for isolating and analyzing cancer cells using a simple blood test. They will study how these cells relate to how chemotherapy works. They hope to use this information to guide choices of treatment for patients in the future.

The main objective of the study is to determine the proportion of patients with M + mutation status among patients with Non Small Cell Lung Cancer adenocarcinoma.

Pancreatic cancer often spreads through local invasion into local structures, including fat, blood vessels, nerves, and nearby organs (stomach, duodenum, spleen, bile duct). Local microscopic invasion is associated with recurrence of pancreatic cancer after pancreatic resection, such that even if the original cancer is surgically removed, microscopic areas of cancer often remain. Data on the patterns of local invasion by pancreatic cancer have not been published. In this study, The investigators hope to investigate the frequency of the various methods of local invasion of pancreatic adenocarcinoma. This would help the investigators better understand how pancreatic cancer spreads, and determine what cancers are not resectable.

This study is being done to determine if a new endoscope will help doctors identify pre-cancer or early cancer lesions in patients who have Barrett's esophagus. This new endoscope allows the doctor to look at the lining of the esophagus in 3 different ways by modifying light.

The goal of this observational study is to learn about in small bowel adenocarcinoma patients. The main question it aims to answer is the association between tumor size and prognosis in patients with small bowel adenocarcinoma. Participants will be compared for the relationship between tumor size and prognosis.

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

With 50% of post-operative biochemical failure, efficient predictive models are needed to guide post-operative management. Radiomic features are quantitative features extracted from medical imaging, supposed to be correlated with tumor heterogeneity. We aim to build and test three predictive models (clinical, radiomic and combined models).

The clinical and derived data from the preoperative computed axial tomography (CT) and Positron Emission Tomography (PET) of patients with pathological stage I pulmonary adenocarcinoma will be analyzed retrospectively, classified according to the current pathological classification IASLC / ATS / ERS of pulmonary adenocarcinoma, subjected to surgical treatment in our Operating Unit between August 2006 and July 2011. A follow-up will be performed on the patients enrolled in the study up to the date of death, and in any case no later than October 31, 2019
