Filter by:FNF-014 is a randomised, open-label, multicentre, parallel-group, phase 3 study in China to prove superiority of POF over S-1/docetaxel in postoperative adjuvant setting for pStage III gastric adenocarcinoma (including adenocarcinoma of the gastrooesophageal junction).
The primary hypothesis is that cancer vaccine can convert non-immunogenic gastric cancer into immunogenic phenotype susceptible to PD1 inhibition. This would lead to an improved radiological response rate and favorable immune contexture for immune checkpoint blockade
Background: Cancer-related fatigue (CRF), one of the indicators of QoL, is one of the most common side effects of cancer and its treatment. However, the pathophysiological mechanisms involved in CRF among cancer patients are not completely understood. Therefore, more in-depth researches on CRF of surgical patients suffering from gastric cancer are needed in Taiwan. Purpose: The purpose of this study is to examine the incidence rate and correlated factors (QoL and immune biomarkers) of CRF among gastric cancer patients undergoing major abdominal surgery. Method: A longitudinal study was conducted to recruit gastric cancer patients who scheduled to operate at surgical clinics from a northern medical center in Taiwan. The data will be collected with a structured questionnaire and Immune markers assessments via purposive sampling of 120 subjects. Before operation, on day 1 after operation, and on day 7 after operation, the biomarkers will be measured. The BFI-T questionnaire will be filled out before surgery and on day 1, 2, 7, 28 after surgery; The EORTC QLQ-C30 and EORTC QLQ-STO22 questionnaire will be filled out before surgery and on day 7, 28 after surgery; Type D scale-14(Taiwanese version) questionnaire will be filled out before surgery and on day 28 after surgery. Data will be analyzed by using descriptive statistics, paired t-test, Chi square test, Pearson's correlation, and the generalized estimating equation (GEE) was used to identify significant factors with QoL after operation. Anticipated achievement: The anticipated achievement of this study is to provide healthcare providers with more knowledge about CRF, and help them to enhance the quality of life on gastric cancer patients in the future.
The purpose of this study is to explore the safety and feasibility of laparoscopic spleen-preserving No. 10 lymph node dissection for patients with advanced middle or upper third gastric cancer.
Gastric cancer remains the third leading cause of cancer-related death worldwide and is especially frequent in East Asia. Fluoropyrimidines are the backbone of first-line chemotherapy for advanced gastric cancer (AGC), and S-1 provides new option with its simplicity and convenience. 5-Fluorouracil (5-FU) was the only efficacious treatment for AGC before the nineties of the 20th century, and afterwards with the discovery of chemotherapy such as cisplatin, oxaliplatin, S-1 and capecitabine, response rate as well as survival had been improved greatly. Most of AGC will progress after first-line treatment; therefore, seeking an efficient and low toxic maintaining regimen to prolong progression-free survival (PFS) becomes a hot topic in oncologic field. Some clinical researches demonstrated maintenance treatment for advanced colorectal cancer (CRC) and lung cancer. The investigators had conducted a phase III clinical trial that demonstrated capecitabine maintenance versus observation prolonged PFS significantly after first-line chemotherapy with FOLFOX or XELOX regimens in advanced CRC. In AGC, several retrospective studies revealed patients receiving 5-FU/leucovorin(LV), capecitabine, or trastuzumab maintaining therapy experienced significantly longer PFS than that stopped chemotherapy after first-line chemotherapy. Some one-arm phase II clinical trials found 5-FU/LV, capecitabine, S-1, capecitabine plus bevacirumab, or capecitabine plus bevacirumab plus trastuzumab maintenance seemed to yield sound PFS and good tolerance. However, there were no randomized controlled clinical trials for maintenance treatment of these regimens in AGC, except that a phase II Chinese randomized controlled trial of Uracil and Tegafur (UFT) versus observation experienced early termination. Above all, so far, there is no data to demonstrate that regular 2-6 months of chemotherapy followed by maintenance treatment could prolong PFS and OS for AGC. S-1 is effective for gastric cancer, and was approved as palliative treatment for advanced gastric cancer and adjuvant treatment; in addition, with its relative less frequency of side effects and convenient oral administration, S-1 as maintenance regimen could be prone to be accepted by patients. Therefore, the current study is designed to investigate that S-1 as maintenance treatment after first-line palliative chemotherapy could improve PFS and OS for patients with advanced gastric cancer through a perspective randomized clinical study.
<Background> 1. Current status of treatment options in advanced gastric cancer. - The cytotoxic chemotherapy, usually fluoropyrimidine + platinum combination regimen is current standard of care. In case of HER2(+) gastric cancer, the addition of trastuzumab on top of cytotoxic chemotherapy is standard of care. - In second-line setting, the cytotoxic chemotherapy in combination with Ramucirumab improved the patients' survival compared with cytotoxic chemotherapy alone. - There are few treatment options for gastric cancer patients who have been treated with more than two lines of palliative chemotherapy. Patients with good performance status even after failure to 2 kinds of palliative chemotherapy still need the active anticancer treatment options. Therefore, this is the high unmet medical need. 2. Current status of immunotherapy development in gastric cancer 3. The importance of tumor microenvironment 4. The role of polarized macrophage in TME 5. The role of polarized macrophage in gastric cancer 6. Potential of combination of PD1 inhibitor and CSF-1 inhibitor Based on these rationales, we hypothesized that the combination of PD1 inhibitor and CSF1R inhibitor might be synergistic in gastric cancer. However, the exact in vivo immune modulation by each inhibitor has not been revealed so far. Therefore, we will conduct this "biomarker study of PDR001 in combination with MCS110 in gastric cancer" to see the biologic dynamic modulation with MCS110 and combination (MCS110/PDR001) and to see preliminary efficacy signal with this combination. <Trial objectives> Primary objective: To see biomarker changes (PDL1, TAM, TIL) by MCS110 monotherapy and MCS110/PDR001 combination (To see the biomarker changes by MCS110 monotherapy at first, then, by MCS110/PDR001 combination in gastric cancer) Secondary objective: To see preliminary efficacy (ORR, irRR, PFS, DOR, DCR, OS) and safety.
The study consists in a co-clinical trial by using zebrafish embryos. Specifically, an observational prospective clinical trial on patients operated of epato-biliar-pancreatic cancers and gastro-intestinal cancers undergoing a chemotherapy treatment will be run concurrently to an animal trial on zebrafish embryos xenotransplanted with patient cancer cells in order to demonstrate that zebrafish model is able to predict the therapeutic regimen with the best efficacy for each patient.
the purpose of this study is to evaluate application value of LCI in the diagnosis of early gastric cancer.
Background: It is known that postoperative malnutrition remains inevitable for gastric cancer patients with adjuvant chemotherapy, which could have prejudicial influence on the compliance of subsequent adjuvant chemotherapy and survival of the patients. A multi-institutional prospective phase 2 study had demonstrated the efficacy of oral nutritional supplements (ONS) for gastric cancer patients undergoing gastrectomy. However, previous studies did not focus the gastric cancer patients with adjuvant chemotherapy. Thus, it is unknown whether the ONS could benefit the gastric cancer patients with adjuvant chemotherapy. A multicenter, phase 3 randomised controlled trial was conducted to compare the ONS with standard diet for postoperative gastric cancer patients with adjuvant chemotherapy. Patients and method: In this study, pathological confirmed stage II-III or T1N1M0 gastric cancer patients who are supposed to receive adjuvant chemotherapy, aged from 18 to 75 years, with body mass index (BMI) from 18.5 to 28.0 kg/m2, and with Eastern Cooperative Oncology Group performance status ≤2, are randomized 1:1 to receive oral administration of NutrenOpimum (Nestle Suisse S.A.), a liquid enteral nutritional food for special medical purpose (FSMP), or standard diet. NutrenOpimum administration was recommended with a dosage of 400 kcal/400 ml per day within 7 days postoperatively and was continued for 3 months postoperatively. The primary end point was postoperative malnutrition, as defined as ratio of the weight loss at 3 months postoperatively to the days 7 postoperatively body weight (body weight loss ratio) higher than 10%; body weight loss ratio at 1, 3, 6 months. Secondary end points were chemotherapy withdrawal, time to adjuvant chemotherapy failure, period of adjuvant chemotherapy, quality of life, grade 3/4 neutropenia, thrombocytopenia, anemia, and severe side effects on digestive tract. Final study analysis will be conducted after the last patient's enrollment.
