Active clinical trials for "Stomach Neoplasms"

Peritoneal metastasis is a major pattern of gastric cancer recurrence and predicts poor prognosis. In our previous study, we developed a next-generation sequencing technology to detect minimal residual cancer cells in peritoneal lavage fluid with a personalized assay profiling tumor-specific mutations in patients with gastric cancer. With this technology, we predicted all the cases that developed peritoneal metastasis in patients with pT4 disease with 100% sensitivity and 91% specificity. Based on this result, a prospective phase 2 clinical trial is designed to evaluate the efficacy of adjuvant intraperitoneal chemotherapy in patients with positive cancer cell DNA detected in peritoneal lavage fluid by our personalized tumor-specific mutation profiling assay.

SOX regimen, consisting of oral S-1 and intravenous oxaliplatin, is the preferred regimen for perioperative chemotherapy for gastric cancer. The goal of this clinical trial is to compare the efficacy and safety between S-1 combined with oxaliplatin by arterial infusion, as neoadjuvant chemotherapy, and conventional SOX regimen, in locally advanced gastric cancer. The main question it aims to answer is: whether arterially infused oxaliplatin plus S-1 has the potential to be a better neoadjuvant option for patients with locally advanced gastric cancer. Participants will be randomised, and receive: 3 cycles of conventional SOX chemotherapy plus PD-1 antibody or arterial infused oxaliplatin plus S-1 and PD-1 antibody, as neoadjuvant chemotherapy; Adequate gastric resection along with D2 lymph node dissection; 3 cycles adjuvant chemotherapy using SOX regimen plus PD-1 antibody. Administration of S-1 regularly till 1 year after surgery. Researchers will compare Major pathological response rate (MPR) ，pathologic complete response rate（pCR）,the 2-year overall survival (OS) rates, 2-year disease free survival (DFS), R0 resection rates, and adverse events, to see if the modified perioperative chemotherapy improve the prognosis of patients with locally advanced gastric cancer.

To evaluate efficacy and safety of peri-operative sintilimab in combination with SOX in resectable locally advanced gastric or gastroesophageal junction adenocarcinoma

This trial is an open-label, single-arm clinical study. The main purpose is to verify the safety and efficacy of CAR-T cell preparations in the treatment of CEA-positive advanced malignant tumors, and to obtain the recommended dose and infusion scheme of CAR-T cell preparations for the treatment of patients with CEA-positive advanced malignant tumors.

Nowadays, while pursuing the eradication of tumor, how to maximize the preservation of normal anatomy and physiological functions of the stomach, reduce the surgical trauma caused by excessive debridement, and improve the quality of life of patients after surgery has become a more important concern in the treatment of early gastric cancer. This prospective multicenter randomized controlled clinical trial was designed to elucidate the oncologic safety of laparoscopic gastric preservation surgery compared to standard laparoscopic gastrectomy. The oncologic safety of laparoscopic gastric preservation surgery with anterior basal dissection (SBD) compared to standard laparoscopic gastrectomy. This trial is an investigator-initiated, multicenter, prospective, randomized, open, parallel-controlled with a non-inferiority design. Patients diagnosed as distal gastric cancer with clinical stage T1N0M0, with a lesion diameter of 3 cm or less were eligible to participate in this study. Patients will be randomized to either laparoscopic stomach-preserving surgery with SBD or standard surgery. The primary end-point is 3-year disease-free survival.

To evaluate the efficacy and safety of Sintilimab combined with apatinib and chemotherapy as First-line or second-line Therapy in Treatment of HER-2 negative MSS Advanced or Metastatic GC or GEJ Cancer. At the same time, the correlation between tissue programmed death ligand-1(PD-L1) expression and blood circulating tumor cell(CTC) counts and the efficacy of immune combination therapy was also explored.

In this phase 2 study, we combined sintilimab, paclitaxel and S-1 as regimen to treat gastric cancer patients with peritoneal metastasis. We are aim to estimate the efficacy and safety of this regimen in the phase 2 study.

The main objective of this study is to evaluate the efficacy and safety of IV FCM(ferric carboxymaltose) in patients with AGC receiving palliative chemotherapy. This study will also evaluate the effect of IV FCM on the treatment outcomes of palliative chemotherapy in patients with gastric cancer receiving fluoropyrimidine and platinum-based regimen in the same 1st-line palliative setting.

This study is being done to find out if zanidatamab, when given with chemotherapy plus or minus tislelizumab, is safe and works better than trastuzumab given with chemotherapy. The patients in this study will have advanced human epidermal growth factor 2 (HER2)-positive stomach and esophageal cancers that are no longer treatable with surgery (unresectable) or chemoradiation, and/or have grown or spread to other parts of the body (metastatic).

For locally advanced gastric/gastroesophageal junction adenocarcinoma (cT3/4aN+M0 ), neoadjuvant therapy can downstage T and N stage, improve R0 resection rate, reduce recurrence and metastasis rates, and finally improve the long-term survival. A combination of Fruquintinib and SOX for locally advanced gastric/gastroesophageal junction adenocarcinoma could be a novel therapy. This study intends to evaluate the efficacy of Fruquintinib plus SOX as neoadjuvant therapy for locally advanced gastric or gastroesophageal junction adenocarcinoma.
