Filter by:To evaluate the short-term outcomes of single-incision plus one-port laparoscopic surgery (SILS + 1) versus conventional laparoscopic surgery(CLS) for distal gastric cancer whose clinical stage was cT1-3N0-2M0
Gastric cancer (GC),including cardia and noncardia gastric cancer, is responsible for over 480,000 new cases in 2020 and an estimated 370,000 deaths, making it the third most frequently diagnosed cancer and the third leading cause of cancer death in China. Majority of patients(63%) are presented with locally advanced gastric cancer (stage Ⅱ/Ⅲ) and the prognosis is poor. Previous studies have shown that patients with pathological complete response(pCR) following neoadjuvant therapy have longer survival. In 2019, Lancet Oncology published the FLOT4-AIO study which testified that perioperative chemotherapy with FLOT (5-FU/LV, oxaliplatin and docetaxel) regimen has improved pCR rate and prolonged progression free survival(PFS) and overall survival(OS) in patients with stage II/III gastric cancer. Moreover, PD-1 blockade such as nivolumab or pembrolizumab in combination with chemotherapy has shown higher objective response rate(ORR) as compared to chemotherapy alone in advanced gastric cancer. The nanoparticle albumin-bound paclitaxel has been recommended as the second-line chemotherapy for unresectable or recurrent gastric cancer based on the Chinese Society of Clinical Oncology(CSCO) guideline. When PD-1 antibody is applied, albumin-bound paclitaxel is considered as a better partner since no pretreatment of corticosteroids is needed. Thus, the investigators plan to conduct a phase II clinical trial to evaluate the efficacy and safety of toripalimab (PD-1 antibody) combined with the FLOAP (albumin-bound paclitaxel, oxaliplatin, fluorouracil and leucovorin) regimen as the perioperative treatment of cT2-4 and/or N+ GC. The primary end point is pCR rate. The secondary end points include disease free survival(DFS), OS, ORR, R0 resection rate, incidence of adverse events(AE).
This study aims to evaluate the use of Next Generation Sequencing (NGS) to detect circulating tumor DNA in gastric cancer patients after gastrectomy
To determine the efficacy and safety of TAS-102 and Anlotinib in patients with metastatic gastric cancer who had been treated with ≥ 2 lines of prior standard chemotherapy
The aim of this study is to develop a protocol for detection of circulating tumor DNA (ctDNA) in plasma of patients with early stages of gastric cancer.
Infigratinib is an oral drug which selectively binds to fibroblast growth factor receptor (FGFR) 1-3. This is a multicenter, open-label, single arm phase IIa study to evaluate the efficacy and safety of Infigratinib in subjects with locally advanced or metastatic gastric cancer or gastroesophageal junction adenocarcinoma with FGFR2 genetic amplification or other advanced solid tumors with other FGFR genetic alternations who have failed in 2nd line or above treatment. This trial includes 2 cohorts (i.e., baskets) with above mentioned indications.
The gastric cancer diagnosis and treatment specifications clearly point out that tumor markers need to be detected in the process of diagnosis, efficacy evaluation and follow-up. However, there is currently a lack of gastric cancer markers with high sensitivity and specificity, and the detection of markers is limited to a single index analysis, which has many shortcomings such as long analysis time, large reagent consumption, and high detection cost. Therefore, this project will use protein chips to detect new types of gastric cancer patient markers and establish a multi-diagnostic model for early screening of gastric cancer. Finally, monoclonal antibodies will be produced against various high-specific tumor markers and a gastric cancer diagnostic kit will be established.
Prospective observational study comparing the use of circular (Orvil) and linear stapler for intracorporeal esophagojejunostomy. Patients with adenocaricinoma involving the esophagogastric junction or the gastric cardia are observed. The two methods of esophagojejunostomy are compared.
The purpose of this study is to determine the safety, tolerability, and preliminary efficacy of pembrolizumab/vibostolimab co-formulation (MK-7684A) with or without other anticancer therapies in participants with selected advanced solid tumors. The primary hypothesis is that pembrolizumab/vibostolimab co-formulation is superior to pembrolizumab alone in terms of objective response rate or progression-free survival in participants with cervical cancer.
Gastric cancer with retroperitoneal lymph node metastasis was considered as unresectable, to improve these patients' prognosis, we designed systematic conversion therapy including immunotherapy and chemoradiotherapy. The purpose of this study is to estimate safety and efficacy of Sintilimab in combination with chemoradiothrapy followed by D2 surgical resection in patients with advanced gastric cancer with retroperitoneal lymph node metastasis.
