Active clinical trials for "Stomach Neoplasms"

If a patient undergoes gastrectomy, which is a kind of major abdominal operation, he/she loses more than 5% of his/her body weight in 2 months after surgery. This point is one of the criteria of 'risk of malnutrition' according to Nutrition Risk Screening (NRS 2002) and the patient who corresponds to this criterion needs nutritional support. According to Nutrition Risk Screening (NRS 2002), moderate malnutrition is defined as the state that the patient orally intakes 25~50% of recommended requirements; severe malnutrition is less than 25%. Meanwhile, when oral nutrition support was provided to patients after gastric cancer surgery, the patients' average daily intake during the first three months was about a half of the recommended requirements. Putting together the facts i) that the patient underwent major abdominal operation, ii) that the weight loss rate exceeded 5% for two months, iii) that the average daily intake of patients during the first three months was about half of the recommended amount, the patients are eligible to be classified as a group who require nutritional support according to NRS 2002. Therefore, it is intended to verify the efficacy and safety of supplemental parenteral nutrition by comparing Arm A, who are provided oral intake with supplemental parenteral nutrition, Arm B, who are provided oral intake only after curative gastric cancer surgery.

This is a prospective one arm phase II clinical study to evaluate the efficacy and safety of TQB2450 (PD-L1 inhibitor), anlotinib combined with oxaliplatin and capecitabine in patients with unresectable locally advanced, recurrent or metastatic gastric cancer or adenocarcinoma of the gastroesophageal junction.

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.

There are more than 75% of patients with gastric cancer who are diagnosed in advanced stage in Vietnam, most of cases in T4a. The purpose of this study is to compare the technical feasibility, early and long term outcomes of open and laparoscopic distal gastrectomy for gastric adenocarcinoma in T4A stage

The main purpose of this study is to compare the safety and efficacy of PIPAC+SOX+OLAPARIB for locally-invaded-gastric cancer (LIGC) patients in China. To obtain preliminary results for designing a new phase II/III randomized controlled trial.

This is a interventional clinical trial to assess the efficacy and safety of combinational therapy of paclitaxel-albumin and S-1 for the neoadjuvant chemotherapy of advanced gastric cancer.

This is a Prospective，Single-center，Single-arm，Open-label exploratory clinical trial evaluating the efficacy and safety of Conversion Surgery for Apatinib plus SOX for patients with unresectable gastric cancer.

Linus Pauling and Dr Ewan Cameron have published two retrospective studies about using high dose vitamin C to treat cancer patients forty years ago. Their studies have shown that high dose vitamin C usage could significantly prolong overall survival of patients with advanced cancer. Recently, preclinical study has shown that human colorectal cancer cells harboring KRAS or BRAF mutations are selectively killed by high levels of ascorbic acid (AA). High dose of AA impairs tumor growth in Apc/KRASG12D mutant mice. Previous phaseⅠclinical trials have found that high dose (1.5g/kg or 90g/m2) iv AA is well tolerated in cancer patients. This protocol is a phase Ⅲ, study of ascorbic acid (AA) infusions combined with treatment with mFOLOX6 versus mFOLOX6 alone as first-line therapy in patients with recurrent or advanced gastric cancer.

The prognosis of Extensive lymph nodes metastatic(ELM) gastric cancer is poor. Chemotherapy occasionally converts it to a resectable cancer. Previous studies showed patients with ELM gastric cancer may obtain a survival benefit from chemotherapy and subsequent curative surgery. The key of conversion therapy of ELMGC is the high response rate. Apatinib, a novel targeted inhibitor of VEGF receptor 2 (VEGFR2), shows significant antitumor activity in the patients with GC. On the basis of our previous Ahead-G325 study, The purpose of this study is to investigate the efficacy and safety of S1/Paclitaxel chemotherapy plus Apatinib in the conversion therapys of ELM gastric cancer.

This multicenter, randomized, double-blind study will evaluate the efficacy and safety of apatinib combined with paclitaxol versus placebo combined with paclitaxol in advanced gastric cancer or gastroesophageal junction carcinoma patients with peritoneal metastasis. Patients will be randomized to one treatment arm: Arm A: apatinib 500mg qd, Paclitaxol 80mg/m2, d1, d8, d15,every 4 weeks ; Arm B: placebo 500mg qd, Paclitaxol 80mg/m2, d1, d8, d15,every 4 weeks ; Tumor assessment will be done every 8 weeks according to RECIST 1.1. The primary endpoint is progression free survival (PFS).
