ABSTRACT
Aim: The administration of total parenteral nutrition [TPN] in terminally ill cancer patients is aggressive with a relatively high risk of complications. In this paper, we investigated the use of TPN in Lebanese cancer patients at end of life. To our knowledge, this is the first study describing TPN administration to Middle Eastern patients with advanced cancer
Methods: We conducted this observational study at Hotel-Dieu de France University Hospital, Lebanon. Eligible cases included all cancer patients that died at our institution between the 1st of January and the 31st of December 2014. The patients and tumors characteristics as well as the management plan were retrieved from the hospital records
Results: Our study enrolled 129 cancer patients at end of life among which 39 percent had received TPN: 28 percent during the last 6 weeks and 34 percent during the last 3 months. The mean duration of TPN administration was 33 days [range: 1 to 211]. The mean duration between the end of TPN administration and death was 37 days [range: 0 to 315]. TPN administration correlated negatively to hyperlipidemia [OR = 0.33; 95 percent CI [0.12 - 0.87]] and to the presence of three cardiovascular risk factors [OR = 0.28; 95 percent CI [0.10 - 0.80]]. On the other hand, it correlated positively to gastrointestinal tumors [OR = 3.9; 95 percent CI [1.3 - 11.7]] and to imaging studies during the last month of life [OR = 3.4; 95 percent CI [1.3 - 9.0]]. In the multivariate analysis, only hyperlipidemia was found to be a significant determinant of the TPN administration [p = 0.010; ORa= 0.29 [0.11 - 0.74]
Conclusion: The prevalent use of TPN at end of life underlines a difficulty in adopting a palliative care approach in our population. This is truly applicable in Middle Eastern populations that seem to refuse a patient-centered supportive care approach
ABSTRACT
Introduction: Localized form of gastric cancer is currently treated, independently of genetic profiles, by surgical resection with perioperative chemotherapy, radiotherapy and/or targeted therapy. Next-generation sequencing (NGS) recently provided new information regarding gene mutations related to gastric cancer pathogenesis. This information can determine new therapeutic pathways to successfully treat gastric cancer depending on its molecular profiling. Ramucirumab is a humanized monoclonal antibody directed against vascular endothelial growth factor receptor 2. Ramucirumab is approved in second-line therapy for advanced or metastatic gastric cancer as a single agent or combined with chemotherapy in molecularly unselected patients. Some studies determined prognostic value of plasma biomarkers and cytokines in patients treated with Ramucirumab (RAINBOW trial). Other studies have shown no relationship between Ramucirumab therapy and VEGFR-2 mutation (REGARD trial). However, no studies have shown significant survival benefit for certain genetic profiles in patients treated with Ramucirumab therapy. The aim of this study is to assess the value of certain molecular profiles in predicting response to Ramucirumab therapy in advanced or metastatic gastric cancer
Methods: This is a retrospective study to determine molecular profiles for gastric cancer that predict outcomes of treatment with Ramucirumab. Patients' molecular profiling will be studied using NGS. Included patients are those with advanced or metastatic gastric cancer treated with second-line Ramucirumab therapy combined with Paclitaxel. Patient characteristics are collected retrospectively from medical records including tumor localization, size, stage, type of surgery, definitive histological subtype, number of lymph nodes resected. Type and response to first line chemotherapy as well as overall survival (OS) and disease free survival (DFS) are acquired for all patients
Results o Kaplan-Meier curves for DFS and OS will be compared between subjects with different somatic mutations using log-rank test. Multivariate Cox regression models for DFS and OS with mutated somatic genes as independent variables were computed. Any predictive factor for response to Ramucirumab, especially molecular, will be reported
Conclusion o Molecular characteristics of advanced gastric cancer patients will be analyzed to define any predictive value for response to Ramucirumab in second-line based therapy
