BACKGROUND Multiplex digital PCR (dPCR) enables noninvasive and sensitive detection of circulating tumor DNA with performance unachievable by current molecular-detection approaches. Furthermore, picodroplet dPCR facilitates simultaneous screening for multiple mutations from the same sample. METHODS We investigated the utility of multiplex dPCR to screen(More)
OBJECTIVES The aim of the study was to compare the postoperative and oncologic outcomes of laparoscopic versus open surgery for gastric gastrointestinal stromal tumors (gGISTs). BACKGROUND The feasibility of the laparoscopic approach for gGIST resection has been demonstrated; however, its impact on outcomes, particularly its oncologic safety for tumors(More)
AIM OF THE STUDY Small bowel adenocarcinoma (SBA) is a rare and aggressive tumour with poor outcomes. Because of its low incidence, the number prospective studies remains insufficient leading to poor knowledge and absence of standard of care. Aiming to better understand small bowel carcinogenesis we investigated the frequency of somatic mutations in a large(More)
The number of CA tandem repeats (CA)n in a highly polymorphic region of EGFR (epidermal growth factor receptor) intron 1 may affect gene transcription; the potential impact of allelic variants on the efficacy of cetuximab in metastatic colorectal cancer (mCRC) patients is debated for long. This study aimed at prospectively estimating the impact of EGFR(More)
INTRODUCTION After curatively intended surgery for colorectal liver metastases, liver recurrences occur in more than 60% of patients, despite the administration of adjuvant systemic chemotherapy. The aim of this study was to assess the benefit of combined adjuvant hepatic arterial infusion (HAI) and intravenous (IV) 5-FU compared with standard modern(More)
The peritoneal cancer index (PCI) is the main prognostic factor for establishing potentially resectable peritoneal metastases from colorectal cancer. Attempts have been made to set a PCI cutoff on which to base indications of complete cytoreductive surgery (CCRS) with hyperthermic intraperitoneal chemotherapy (HIPEC), but none have reached consensus. The(More)
Colorectal cancer is the second most common cause of cancer-related death in the United States. Recent studies showed that interleukin-8 (IL-8) and its receptors (CXCR1 and CXCR2) are significantly upregulated in both the tumor and its microenvironment, and act as key regulators of proliferation, angiogenesis, and metastasis. Our previous study showed that(More)
PURPOSE Recent evidence suggests that cancer stem cells (CSC) are responsible for key elements of colon cancer progression and recurrence. Germline variants in CSC genes may result in altered gene function and/or activity, thereby causing interindividual differences in a patient's tumor recurrence capacity and chemoresistance. We investigated germline(More)
The pharmacogenomics field is crucial for optimizing the selection of which chemotherapy regimen to use according to the patient's genomic profile. Indeed, the individual's inherited genome accounts for a large proportion of the variation in his or her response to chemotherapeutic agents both in terms of efficiency and toxicity. Patients with metastatic(More)
