Active clinical trials for "Stomach Neoplasms"

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).

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.

The purpose of this study is to determine the Objective Response Rate (ORR) of zolbetuzimab as a single agent as assessed by an independent central reader. This study will also assess the ORR and Progression Free Survival (PFS) of zolbetuximab in combination with mFOLFOX6 (with or without Nivolumab) and in combination with pembrolizumab, assess the safety and tolerability, assess the effects on CLDN18.2 expression and assess the immunogenicity and immunomodulatory effects of zolbetuximab as a single agent and in combination with mFOLFOX6 (with or without Nivolumab) and in combination with pembrolizumab. This study will also evaluate the pharmacokinetics (PK) of zolbetuximab, oxaliplatin, fluorouracil (5-FU), and pembrolizumab, evaluate health-Related Quality of Life (HRQoL), evaluate the Disease Control Rate (DCR), Duration of Response (DOR), PFS of zolbetuximab as a single agent, in combination with mFOLFOX6 (with or without Nivolumab) and in combination with pembrolizumab based on both investigator and independent central reader assessment, assess Overall Survival (OS) of zolbetuximab as a single agent and in combination with pembrolizumab.

Previously untreated patients with limited metastatic stage (see protocol for details on criteria) will receive 4 cycles of FLOT (5-Fluorouracil, Leucovorin, Oxaliplatin and Docetaxel). Patients without disease progression will be randomized 1:1 to receive additional chemotherapy cycles (4-8 cycles of FLOT) or surgical resection followed by subsequent chemotherapy (4-8 cycles of FLOT). Main objective of the study is overall survival. Most important secondary objective is the quality of life under treatment and during follow-up.

This phase I/II trial studies the best dose and how well trifluridine/tipiracil hydrochloride combination agent TAS-102 (TAS-102) and nanoliposomal irinotecan work in treating patients with gastrointestinal cancers that have spread to other places in the body (metastatic) or cannot be removed by surgery. Drugs used in the chemotherapy, such as trifluridine/tipiracil hydrochloride combination agent TAS-102 and nanoliposomal irinotecan, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading.

Although Laparoscopic gastrectomy for both early and locally advanced gastric cancer has gained popularity, the use of laparoscopic total gastrectomy for proximal advanced gastric cancer is still limited to some experienced surgeons, because of its technical difficulties in D2 lymph node dissection and anastomoses. Some retrospective and cohort studies regarding laparoscopic total gastrectomy with lymph node dissection suggested the likelihood of application of laparoscopic surgery for proximal gastric cancer. However, there has been no randomized clinical trial comparing results of laparoscopic total gastrectomy with D2 lymph node dissection with open conventional surgery. Therefore, we aimed to verify the efficacy of laparoscopic total gastrectomy with D2(D2-10) lymph node dissection, technical and oncologic safety compared with open surgery via multicenter randomized clinical trial.

A randomized controlled two-armed phase III trial for gastric cancer patients with peritoneal dissemination. Randomization between gastrectomy + cytoreductive surgery + HIPEC (experimental arm) and palliative systemic chemotherapy (standard arm).

Our study aims to compare the efficacy and safety of Chemotherapy Alone Versus D2 distal gastrectomy and metastasectomy plus Chemotherapy for gastric cancer (GC) with one non-curable Factor

This is a Phase II study to determine the efficacy of SBRT to treat liver metastases in patients with Colorectal Adenocarcinoma, Carcinoma of the Anal Canal and Gastrointestinal Neuroendocrine Tumors that are not amenable to surgery. Patients should have no evidence of extra-hepatic disease or have disease that is planned to be treated with curative intent. Therefore, SBRT is being considered as a potentially curative procedure.

Concurrent chemoradiotherapy has been demonstrated a significant improvement in overall survival and disease-free survival according to Intergroup Trial 0116 in patients with gastric cancer after surgical resection. However,there are still many patients experiencing local recurrence or distant metastasis after adjuvant chemotherapy and concurrent chemoradiotherapy for locally advanced gastric cancer after resection. The optimal and standard regimen for adjuvant treatment has not been established in locally advanced gastric cancer yet.The investigators designed the trial to investigate the efficacy and safety of docetaxel plus cisplatin regimen as adjuvant chemotherapy and concurrent chemoradiotherapy regimen compared with classical FOLFOX6 regimen as adjuvant chemotherapy and 5-FU/CF as chemoradiotherapy in patients of locally advanced gastric cancer after D2 radical resection.
