Totally, 38.8% HCCs were found to be drugable in single-site sample, of which only 19.4% might be biased by ITH. Of the driver genes, 86% could be detected in single-site sample. HCC is a highly heterogeneous disease. While ITH indeed hinders comprehensive and precise HCC genome profiling, it has limited influences on identification of actionable and driver mutations. Single-site sampling/biopsy assayed with targeted deep sequencing might be efficient in the clinical management of HCC. 2020 Journal of Gastrointestinal Oncology. All rights reserved.Gastric cancer is a lethal malignancy due to the combination of late-stage presentation, propensity for early metastasis, and lack of effective systemic therapies. Given the high rates of gastric peritoneal metastasis, both macro- and microscopic, regional therapy represents both an attractive and rational treatment option for patients given its success in other peritoneal surface malignancies. Bidirectional chemotherapy (intraperitoneal and intravenous) for treatment of metastatic gastric cancer has not been evaluated prospectively in a contemporary North American cohort. Here we present the rationale and design of a phase II clinical trial of intraperitoneal paclitaxel in combination with intravenous paclitaxel and oral capecitabine. We hypothesize that the combination of systemic and regional chemotherapy may result in improved progression free survival (PFS) for patients with gastric adenocarcinoma and peritoneal-only metastasis. In addition to studying clinical outcomes associated with this treatment regimen, both basic and translational science efforts are planned to better understand this complex malignancy. 2020 Journal of Gastrointestinal Oncology.
