Filter by:Background. Gastric cancer surgery is associated with high risk for postoperative morbidity and mortality. Anastomotic leak (AL) is one of the worst complications associated with relevant short and long-term sequelae. Procalcitonin (PCT) is a biomarker used to monitor bacterial infections and guide antibiotic therapy and has been shown to have better predictive value of AL after colorectal surgery than C-reactive protein (CRP) and white blood cell count (WBC). Purpose. Investigators designed a monocentric pilot study to test if PCT might be a sensitive and reliable marker of AL after gastric surgery
The overall purpose is to develop and maintain a multi-institutional database comprising of information regarding surgical, clinical and oncological features of patients that will be treated for gastric cancer with robotic, laparoscopic or open approaches and subsequent follow-up. The main objective is to compare the three surgical arms on surgical and clinical outcomes, as well as on the oncological follow-up.
Nowadays, the proportion of patients with locally advanced gastric cancer is estimated up to 90 percent of all gastric cancer cases in Russian Federation. Surgical procedure with D2 Lymphadenectomy is the main option for treatment. Conventional open approach is still the current standard for advanced gastric cancer. Laparoscopic procedures for gastric cancer as minimally invasive surgery has gained popularity for the treatment of early gastric cancer in East Asia. Several studies indicated that laparoscopic procedures both total and subtotal gastrectomy with D2 lymphadenectomy is a technically feasible and safe procedure by experienced surgeons in high-volume specialized hospitals. However, lack of solid evidence on the oncologic efficacy. Starting clinical trials for evaluate safety of oncology laparoscopic subtotal gastrectomy for locally advanced gastric cancer. Aim of this trial is show safety, feasibility and oncologic efficacy of Laparoscopic radical surgical procedures both total and subtotal gastrectomy for treatment gastric cancer.
Outcome measurement for patients with gastric, ovarian, colorectal, or pleural cancer/mesothelioma with peritoneal/pleural carcinomatosis undergoing pressurized intraperitoneal/intrathoracal aerosol chemotherapy (PIPAC/PITAC) with cisplatin and doxorubicin or oxaliplatin. Record of (partial/total) tumor response rate via survival rate, time until tumor progression (according to RECIST-criteria), peritoneal carcinomatosis index (PCI) before and after therapy, histological tumor progression/regression, ascites/pleural affusion volume, degree of tumor cell apoptosis.
This study investigates the safety and feasibility of laparoscopic-assisted total gastrectomy with spleen-preserving splenic hilum lymph node dissection for proximal advanced gastric cancer and compares the early results of this procedure with open total gastrectomy.
The Advantages and Disadvantages Between Uncut Roux-en-Y Reconstruction and Billroth II Reconstruction After Laparoscopy-assisted Distal Gastrectomy for Gastric.
The evaluation of the chemotherapy efficacy for gastric cancer patients is usually evaluated by computer tomography scans with RECIST criteria that are performed every two months during the treatment. The management of treatment for gastric cancer needs the development of early biomarkers to evaluate the efficacy in order to avoid unnecessary toxicity in case of early chemotherapy resistance. In this prospective study, we will compare the monitoring of circulating tumor DNA with the results of CT scan according the RECIST criteria and the blood level of CEA and CA 19-9 tumor markers. Thus, the objective of this study is to identify a prognostic and/or predictive biomarker of tumor response according to the tumor DNA circulating assessment in gastric cancer treatment, in order (i) to avoid an unnecessary toxicity of an ineffective treatment that it would be continued uselessly, (ii) and to allow a early changing to an alternative chemotherapy regimen.
The aim of the project is to study the role of minimally invasive imaging methods, such as magnification endoscopy with narrow-band imaging (M-NBI) combined with confocal laser endomicroscopy (CLE), in correlation with immunohistochemical analysis, for assessing the angiogenesis status of patients with gastrointestinal tumors, in particular with colorectal and gastric cancer. Angiogenesis, i.e. the process of forming new blood vessels, represents an essential event for tumor growth and metastasis and the importance of its understanding stems from potential applications for diagnosis, prognosis stratification and mainly from the possibility of developing and improving targeted therapies. While current methods for evaluating tumor vascularity are based on immunohistochemistry techniques with microvascular density (MVD) calculations, these imply repeated tissue sampling and are not feasible in the context of clinical practice. Imaging techniques might overcome limitations associated with MDV measuring, obtaining both functional and morphological information and enabling repeated evaluations that are necessary for the assessment of a dynamic process as angiogenesis during follow-up of targeted therapies. NBI is a digitally enhanced endoscopic imaging technique that uses optical filters to illuminate tissue with light at blue and green wavelengths. These are selectively absorbed by hemoglobin and, as a result superficial vascular networks are highlighted and morphological changes in capillary patterns can be described for different lesions. CLE represents a revolutionary technology that enables endoscopists to collect real-time in vivo histological images or "virtual biopsies" of the gastrointestinal mucosa during endoscopy, and has raised significant interest for the potential clinical applications and numerous research possibilities. After intravenous administration of fluorescein as a contrast agent, CLE enables real-time visualization of the tumor vasculature, which is structurally and functionally altered compared to the normal vascular networks. Therefore M-NBI will be used for enhanced visualization of morphological changes of the superficial capillaries, while CLE will be directed towards vascular regions of interest for characterization of these changes at the microscopic level. Furthermore, imaging studies will be backed by MVD calculation using immunohistochemical methods, based on tissue samples harvested during endoscopic procedures.
The purpose of this study is to explore the role of adjuvant chemo-radiotherapy in patients with local advanced gastric cancer.
The current commonly used for distal gastri cancer in gastrointestinal anastomosis is Roux-en-Y. However, the complications after Roux-en-Y reach an incidence of over 30% which involve nausea, vomiting, and abdominal distension. The underlying mechanism might be the result of interruption of intestine peristalsis. In 2013, Kim reported total laparoscopic uncut Roux-en-Y anastomosis could reduce Roux stasis syndrome incidence by keeping the continuity of jejunum. In September 2014, we carried out this operation in 30 cases in our centre. Our previous results showed that this operation had a low postoperative complication and short hospitalization time, indicating uncut Roux-en-Y anastomosis might be a safe procedure. However, some limitations are noticed. The report from South Korea is a retrospective study and the evaluation of QOL is certain subjective. Here, we aimed to perform the first randomized controlled clinical study on uncut Roux-en-Y anastomosis to improve QOL of patients after laparoscopic distal gastrectomy.
