Filter by:Gastro-esophageal adenocarcinoma is one of the most common cancer in the world and the fourth most common cancer in France with more than 6,000 cases per year. For non-metastatic patients, a preoperative chemotherapy is recommended. As colorectal adenocarcinomas, gastroesophageal cancers (OGC) could be caused by a failure of DNA repair related to the loss of expression of one of the DNA repair proteins (MLH1, MSH2, PMS2, MSH6) (deficient MMR (dMMR)). The prevalence of tumors with dMMR is evaluated at 14% (Choi et al, 2014; Kim et al, 2015). This proportion reaches 25% among patients over 70 years old. Evidence suggests that patients with dMMR tumors do not benefit from neoadjuvant chemotherapy (Smyth et al, 2017), which may even have a negative impact, especially in elderly patients, and which should be discussed in this particular situation. The decision of neo-adjuvant chemotherapy must be taken very quickly after the endoscopic diagnosis. The investigators will evaluate the diagnostic performance of the determination of dMMR status by endoscopic biopsies of OGC. Moreover, there is no clear recommendation for the determination of dMMR status in OGC especially regarding the size of the forceps to use to ensure the quality of samples and the best molecular techniques for dMMR status determination. Methods In this prospective study, the investigators will include patients who will benefit from an upper endoscopy within 5 French hospital centers (Saint-Louis, Lariboisière, Beaujon, Bichat and Avicenne) linked to the NORDICAP network. If a suspect lesion of OGC is discovered during the gastroscopy, the endoscopist will perform at least 8 endoscopic biopsies, according to the recommendations, and by the mean of 2 kinds of forceps: standard biopsy forceps and a large capacity biopsy forceps. The clinical and follow-up data will be prospectively collected and will include demographics data, cancer stage, lymph node invasion, treatment history, recurrence and survival data. The investigators will assess MSI status by genotyping and MMR proteins expression by immunochemistry (IHC), performed, for each patient, on both biopsies and surgical tumor samples. Expected results This study will allow us to compare diagnostic performance of endoscopic biopsies to surgical samples for the assessment of dMMR status. Likewise, the investigators will compare the diagnostic performance of the two kinds of endoscopic forceps and of IHC and genotyping for the determination of dMMR phenotype. It will enable us to establish recommendations for the benefit of gastro-enterologists and pathologists.
Homologous Recombination Repair (HRR) gene mutations can be detected in many solid tumors, patients with HRR gene mutations may benefit from PARP inhibitor. Antiangiogenic drugs can induce hypoxia and increase the sensitivity to PARP inhibitor. The combination of PARP inhibitor and antiangiogenic drug can play a synergistic anti-tumor role and achieve good efficacy in HRR gene-mutated tumors. The purpose of the study is to determine the dose limiting toxicity (DLT) and maximum tolerable dose (MTD) of Niraparib plus Anlotinib in HRR gene-mutated advanced solid tumors, and evaluate the safety and effectiveness of this combination therapy preliminarily.
Lung cancer is one of the most frequent cancer concerning human beings and it represents, worldwide, one of the first cause of death. Most of patients with this cancer are males and 85% of lung cancers are non-small cells type (NSCLC) with adenocarcinoma being the most common histologic subtype. Patients with pulmonary cancer have a poor long-term prognosis with an overall 5 years of survival which is less than 25% for all stages. The natural immune system, with polynuclear neutrophils (PNN) is involved in carcinogenesis. The impact of PNN localized within the tumor as a prognostic biomarker has not been really studied in non-small cells lung cancers. According to some studies, an increase in the number of PNN (labelled by the CD66b antibody) within the tumor is associated to a greater risk of relapse and a poor overall survival rate. The intra-tumoral ratio PNN over Lymphocytes T CD8 + (iNTR) is an independent factor of the poor prognosis concerning the overall survival rate and concerning risk of relapse with patients who went through a first surgery for a non-small cells lung cancer. With this study we will initially concentrate on lung adenocarcinoma and attempt to evaluate the PNN's rate within the tumor and its impact on an overall survival rate and progression-free survival. Secondly, we will explore the role of iNTR and the mutational profile of tumors concerning this survival.
Lung adenocarcinomas (LUADs) from Asian ancestry are reported to have different genomic architectures compared with LUADs from Caucasian ancestry. However, due to lack of available cases, few studies controlled the clinical attributes during the comparisons of the genomic alterations. In this study, the investigators will identify Asian LUADs patients who had broad-panel next-generation sequencing (NGS) performed on their primary tumor between January 2018 and December 2019 at the department of thoracic surgery of Peking University People's Hospital. Then, Caucasian LUADs patients who had targeted NGS (Memorial Sloan Kettering-Integrated Mutation Profiling of Actionable Cancer Targets [MSK-IMPACT]) will be identified in the GENIE database, which consists of 6673 primary lung adenocarcinoma samples with clinical annotations. Finally, genomic alterations regarding somatic mutations, copy number variations, fusions, mutational signatures, oncogenic pathways, and therapeutic actionability will be comprehensively compared between these two cohorts after adjusting age, sex, smoking status, and pathologic stage using propensity score matching. This study will elucidate important ancestry differences between Asian and Caucasian lung adenocarcinoma patients.
This clinical trial is to evaluate the efficacy and safety of subjects with metastatic gastric adenocarcinoma or adenocarcinoma of the gastroesophageal junction. In addition, this clinical trial is performed to analyze the genome-specific response rate and genome analysis to identify predictive markers that respond to investigational drug administration.
This is a study of Camrelizumab in Combination With concurrent radiotherapy and SOX for Initial Unresectable or potentially resectable proximal Gastric or Gastroesophageal Junction (GEJ) Adenocarcinoma. Patients without prior palliative therapy will be treated with Camrelizumab, radiotherapy (total 45 Gy), Oxaliplatin, and S-1. The primary endpoint is the 1-year PFS rate.
The purpose of this study is to evaluate the efficacy and safety of the study drug known as KH903 in participants with gastric and gastroesophageal cance
A large-scale, high-throughput, multi-dimensional comprehensive study of PDAC multiomics will be carried out. In this study, clinical specimens of resected PDAC collected by our research group from 2017 to 2019 will be selected as research objects.Tumor tissues and their adjacent non-tumor tissues from more than 200 PDAC patients are expected to be used for genome, transcriptome sequencing and mass spectrometry analysis of proteome and phosphorylated proteome.Combined with the data results of multiomics, bioinformatics analysis and network database information, we will clarify the relationship between multiomics of pancreatic cancer and established the new subtyping of pancreatic cancer proteome. A molecular landscape of the progression of pancreatic cancer at the genome-transcriptome-proteome level provides new therapeutic targets to improve the prognosis of this deadly disease.
Patients with unresectable or metastatic gastric or esophageal cancer, with first-line treatment applied are to be recruited in the study. In the current study, the efficacy and safety of anlotinib hydrochloride combined with nivolumab as second-line or salvage chemotherapy will be evaluated in Chinese patients with advanced gastric adenocarcinoma and esophageal squamous cell carcinoma. 48 patients could provide adequate precision rather than controlling type I&II error.
This study is to evaluate the efficacy and safety of Jin-yuan-kang granule in the treatment of lung adenocarcinoma (LUAD) preliminarily, and provide reference for further study.
