Filter by:The goal of this study is to compare the tumor response in gastric cancer patients given neoadjuvant chemotherapy with the corresponding result obtained from zebrafish patient-derived tumor xenograft(PDX) model given the same regimen. The main question it aims to answer is whether this PDX model of zebrafish could accurately predict the effect of chemotherapy in advanced gastric cancer. Participants will be given the standard neoadjuvant treatment administrated by their own doctors and tumor response will be observed and recorded. Meanwhile, tumor samples derived from patients before chemotherapy will be transplanted to zebrafish and the same regimen will be given to the PDX models correspondingly. The tumor response data both from clinical practice and PDX model platform will be analysed and compared to evaluate the power of this zebrafish model platform in drug efficiency prediction.
To evaluate the clinical efficacy of albumin paclitaxel combined with carelizumab and FLOT in the neoadjuvant treatment of locally advanced gastric cancer with different immune types
The goal of this clinical trial is to explores the effect of marital self disclosure intervention on fear of cancer recurrence and dyadic coping ability in gastric cancer survivors and their spouses. The main questions are: What is the level of fear of cancer recurrence among gastric cancer survivors and their spouse? What is the level of dyadic coping ability among gastric cancer survivors and their spouse?What is the effect of marital self-disclosure intervention on fear of cancer recurrence and dyadic coping ability in the gastric cancer survivors and their spouses? Participants will accept the intervention of marital self disclosure for 4 times (4 cycles of chemotherapy) with different topics. Researchers will compare with control group to see if the level of fear of cancer recurrence and dyadic coping ability will be improved.
This study will be conducted to understand real-world treatment patterns, participant characteristics (demographic and clinico-pathological characteristics), clinical outcomes and safety of different treatment regimens, and healthcare resource utilization in East Asia for HER2-positive locally advanced or metastatic gastric or gastroesophageal adenocarcinoma (de novo advanced disease, relapsed/progressed) in a real-world setting.
The data of 460 gastric cancer patients who underwent curative gastrectomy with D2 lymph node dissection between January 2017 and February 2022 were analyzed. The clinicopathological features and prognosis of the patients with EBV-positive gastric cancers were compared with those of EBV-negative gastric cancers. Immunohistochemistry for epidermal growth factor receptor (EGFR), C-erb B2, Ki-67, and p53 was performed. Additionally, in situ hybridization was conducted to detect EBV, and microsatellite instability (MSI) analysis was used to assess the deficiency in mismatch repair (MMR) genes.
This is a single-arm, phase II study of camrelizumab combined with SOX regimen in subjects with resectable locally advanced gastric cancer. The patients will receive camrelizumab ,S-1 and oxaliplatin given every 3 weeks for 3 cycles as neoadjuvant therapy. After the surgery, adjuvant therapy which includes camrelizumab and SOX regimen will begin.
Nearly 10,000 people die each year in the United Kingdom from cancer of the lower gullet and stomach, known as known as oesophago- gastric adenocarcinoma (OGC). OGC is detected late as symptoms are non- specific and often mistaken for common problems such as heartburn. This translates to fewer than 2 in every 10 patients diagnosed with OGC living longer than 5 years. The breath of people with OGC is enriched with volatile chemicals (VOCs) that indicate cancer. When measured in a breath test, it detects OAC 80 out of 100 times. Whilst encouraging, there is scope to improve the detection rate by giving patients a stimulant drink that amplifies the production of tumour specific VOCs only, to increase their detection in the breath test. The goal of this observational study is to produce an enhanced second-generation breath test with superior ability to detect OGC through augmentation of breath. This will improve long term survival from cancer using an entirely non- invasive test. All participants (cancer and control participants) will consume an oral stimulant drink (OSD) and provide breath samples pre and post consumption of the drink at set time points (maximum 2 hours after consumption of the drink). The investigators will compare the breath VOCs from both groups, before and after consumption of the OSD to see if the OSD has a desired augmentation effect and can improve the accuracy of the OGC breath test. With this second-generation breath test, participants with vague symptoms can undergo a quick, non- invasive test, have samples analysed in a safe and accurate manner and be subsequently stratified based on their risk of having OGC, leading to earlier disease detection and improved clinical outcomes.
Adult patients undergoing elective non-cardiac surgery were enrolled. Anxiety before the operation was evaluated by The State Anxiety Inventory (S-AI). Logistics regression would be used for identifying the independent factors of preoperative anxiety and prediction model would be established.
Recently, a number of clinical studies were carried out to evaluate the therapeutic effects of PD-1 antibodies combined with chemotherapy as preoperative neoadjuvant therapy of gastric cancer (GC) worldwide. Indicators such as PD-L1 expression, TMB and MSI are currently used to evaluate the efficacy of PD-1/PD-L1 monoclonal antibody therapy. However, these biomarkers are mainly used in patients with metastatic and unresectable tumors, and the conclusions obtained in different studies are still partially contradictory, failing to accurately guide the treatment. Therefore, it is urgent to explore highly sensitive and specific biomarkers that can be used to monitor the efficacy of neoadjuvant immunotherapy for GC.The present clinical trial aims to use ctDNA dynamic monitoring combined with multi-omics methods to evaluate PD-1 monoclonal antibody (sintilimab) combined with SOX neoadjuvant therapy for clinical stage III gastric/gastroesophageal junction adenocarcinoma. In order to identify the suitable population for neoadjuvant immunotherapy for locally advanced and resectable G/GEJ adenocarcinoma.
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.
