Filter by:The aim of the study will be to analyze the microbiome in the blood and stomach in patients with intestinal metaplasia (IM) and / or gastric cancer (GC). As far as IM is concerned, it has been found that the incomplete type is related to GC mainly intestinal-type. Studies show differences in the microbiome in patients with IM and in patients with GC, but do not specify whether these differences are related to histological types. Our intention is to further analyze the microbiome based on histological types. Most studies on stomach cancer have focused on the microbiota of gastric microbiota. Recent data have shown that the microbiome of the small intestine, especially the mucosa, can play a key role in the condition of the gastrointestinal tract. Disturbance of the microbiome of the small intestine has been found in celiac disease, chronic liver disease, diabetes and irritable bowel syndrome. However, information on the role of the microbiome in IM remains limited.
A Phase 2, Multicenter, Open-Label Study of DKN-01 in Combination with Tislelizumab ± Chemotherapy as First-Line or Second-Line Therapy in Adult Patients with Inoperable, Locally Advanced or Metastatic Gastric or Gastroesophageal Junction Adenocarcinoma
For second-line chemotherapy for metastatic gastric cancer, single-agent irinotecan is the standard treatment. Anthracyclines are active but lack well designed investigations. The combination of epirubicin, fluorouracil and cisplatin (or oxaliplatin) are widely used in Europe. However, traditional anthracyclines are more cardiotoxic; and (Pegliposomal Doxorubicin) PLD, as a new liposome dosage form of doxorubicin, has better cardiac safety. Therefore, we designed this phase II trial with PLD and 5-Fu to compare irinotecan monotherapy in the second-line treatment.
Gastric cancer is one of the most common malignant tumors of the digestive tract. Gastric cancer patients diagnosed for the first time in China have a higher proportion of advanced stages and a higher postoperative metastasis rate. Studies have shown that patients with good pathological response after preoperative neoadjuvant therapy (such as tumor regression grade, TRG0 or 1) have a better prognosis. The AIO-FLOT4 study found that preoperative perioperative FLOT chemotherapy not only prolonged the progression-free survival (PFS) time and overall survival (OS) time of patients with advanced gastric cancer, but also increased postoperative pathological remission rate. How to further improve the efficacy of the perioperative treatment plan may be beneficial to improve the long-term survival of gastric cancer patients. Several clinical studies have also confirmed that PD-1 antibody significantly prolongs the life of gastric cancer patients who have failed advanced chemotherapy in the back-line treatment. Thus the investigators plan to conduct this clinical trials to evaluate the safety and efficacy of Toripalimab (PD-1 antibody) combined with FLOT regimen in the perioperative period.The secondary end points included pathological remission rate, resection rate, D2 radical resection rate, 5-year disease-free survival (DFS) rate and 5-year OS rate.
Background. Peritoneal carcinomatosis is a frequent and deadly localization of gastric cancer. Available imaging techniques have a low accuracy in detecting small peritoneal nodules, and direct laparoscopic visualization may fail too. A more accurate staging technique would be advantageous for individualization of therapeutic path. Indocyanine Green (ICG) fluorescence imaging has been reported as a tool for visualizing small peritoneal seedings due to the "enhanced permeability and retention" (EPR) effect of cancer nodules. Aim. To explore the feasibility and effectiveness of fluorescence-enhanced peritoneal carcinomatosis detection in patients with gastric cancer undergoing staging laparoscopy. Methods. This prospective, multicentric, single arm study will include patients with gastric cancer, without a radiological suspicion of peritoneal carcinomatosis, undergoing staging laparoscopy. An intravenous injection of ICG is given at different dosage and at different timepoints before the intervention. During the staging laparoscopy, the abdominal cavity exploration is performed using standard white-light, and subsequently using fluorescence imaging. Suspicious nodules are harvested, until a maximum of 5 per patient, and sent for definitive histological examination. Peritoneal washing is also harvested for cytologic assessment in all cases. The eventual benefit of fluorescence imaging in terms of additional peritoneal lesions that were not detected during standard white-light imaging is evaluated. Discussion. This study will establish if fluorescence imaging increases sensitivity and/or specificity of staging laparoscopy in detecting peritoneal carcinomatosis from gastric cancer. Improved accuracy may translate in better care path selection.
To compare the short-term surgical safety and postoperative quality of life of totally laparoscopic versus laparoscopy-assisted total gastrectomy and to evaluate the superiority of totally laparoscopic total gastrectomy.
This is a single arm study to evaluate the efficacy and safety of CEA-targeted CAR-T cells therapy for patients with relapsed/refractory CEA+ Cancer,and obtain the recommended dose and infusion plan.
This is a prospective, single-center, single-arm, open-label clinical study, aiming at evaluating the efficacy and safety of camrelizumab for injection, apatinib mesylate and tegio for first-line refractory patients with advanced gastric cancer.
This is a study for participants with advanced gastric or gastroesophageal junction adenocarcinoma who have had tumor progression after first-line platinum-contained therapy. The primary study hypotheses are that camrelizumab (SHR-1210) combined with apatinib prolongs overall survival (OS) for participants with tumors that show positive programmed cell death ligand 1 (PD-L1) expression.
Gastric carcinoma is the second most common cause of cancer-related deaths and its main treatment modality if potentially curable is surgery but the optimal surgical resection is controversial. The aim of the current study was to assess the outcomes of curative D2 compared to D1 gastrectomy of operable gastric carcinoma regarding postoperative morbidity and mortality, disease recurrence and survival rates.
