Active clinical trials for "Adenocarcinoma"

The primary objective is to study the feasibility and efficacy of individually optimized CE 4D-CT for PDA in radiotherapy simulation.

This prospective, open-label, single arm, non-interventional study will investigate the effectiveness of bevacizumab monotherapy in participants with lung adenocarcinoma who previously received 4 to 6 cycles of induction platinum doublet plus bevacizumab.

For preoperative staging and prediction of peritoneal dissemination of gastric adenocarcinoma, usage of serum and peritoneal levels of carcinoembryonic antigen (CEA) and CA 19-9 may be helpful. Additionally, the prognosis of the patients with gastric adenocarcinoma treated with gastrectrectomy may be associated with serum and peritoneal levels of tumor markers.

The goal is to improve surgery by preventing tumor cells from being left behind at the time of surgery. This includes finding residual tumor cells in the wound after surgery.

This trial studies the mechanisms of metabolic and hormone action on plaque formation in brain and carotid vessels in patients with prostate adenocarcinoma. Studying the biomarkers in the laboratory may help doctors know the impact of androgen deprivation on metabolic, brain and cardiovascular endpoints.

To identify unique blood markers in cancer patients so that we can identify patients with evidence of pre-existing immunity who may be a responder to immunotherapy.

This is an exploratory, translational, non-interventional and multi-centre clinical study. The aim of the study is to identify predictive plasma biomarkers of response to chemotherapy in PDAC.

This prospective study includes patients with histologically proven cancer of the esophagogastric junction (Siewert Type II and III) and the stomach. Aim of the study is to evaluate the accuracy of PET-CT for the preoperative assessment of lymph node metastasis. The evaluation includes a combination with standard diagnostic tools (endoluminal ultrasound, CT and diagnostic laparoscopy prior to neoadjuvant therapy). Standardized D2-lymphadenectomy is performed and individual lymph node stations (Nr 1-12 according to the Japanese classification) are histopathologically examined. Furthermore we evaluate the role of the PET-CT for early metabolic response evaluation in patients receiving neoadjuvant chemotherapy. Trial with surgical intervention

This pilot clinical trial studies targeted biopsies in determining response in patients with prostate cancer undergoing high-dose-rate brachytherapy (a type of radiation therapy in which radioactive material sealed in needles, seeds, wires, or catheters is placed directly into or near a tumor). Studying tumor tissue obtained before and after treatment may help doctors understand changes in a pathway that looks at how deoxyribonucleic acid (DNA) is repaired after it is damaged and to see if there are differences in the prostate tissue prior to and after starting androgen deprivation therapy.

Colorectal cancer is the third most common tumour in the UK, Netherlands and Denmark with 41000, 14000 and 4000 new cases per year respectively. Standard primary radical Total Mesorectal Excision (TME) surgery is an oncologically effective treatment for early stage rectal cancer. However, resection of a low rectal tumour requires a permanent stoma in approximately 5-10% of cases while many more patients have a temporary stoma, some of which are not reversed. Radical surgery, which evolved to treat locally advanced, symptomatic tumours, may not be the optimal method of treatment for early screen-detected tumours and an organ preserving strategy may generate significantly less morbidity without substantially compromising oncological outcomes. TREC was a randomised phase II trial to test the feasibility of randomisation between TME and an organ preserving policy of short course pre-operative radiotherapy (SCPRT) delay followed by transanal endoscopic microsurgery (TEM). STAR-TREC is a phase II feasibility study that will evaluate whether it is possible to accelerate the patient recruitment attained in the TREC study, to 4 per month in the first year of recruitment and 6 per month in the second. This would demonstrate deliverability of a phase III study.
