Abstract
BACKGROUND Patients with glioblastomas have a dismal prognosis, and there is no circulating predictive or prognostic biomarker. Circulating progastrin, hPG80, is a tumor-promoting peptide present in the blood of patients with various cancers that has been shown to have prognostic value. We evaluated the prognostic value of plasma hPG80 in patients with isocitrate dehydrogenase-wild type glioblastoma after surgery. PATIENTS AND METHODS A multicentric retrospective study in glioblastoma patients treated with standard radio-chemotherapy was conducted. The hPG80 levels were measured in plasma EDTA samples collected after surgery with an ELISA DxPG80.lab kit (Biodena Care, Montpellier, France), which has a detection threshold of 1.2 pM. The relationship between post-operative hPG80 plasma levels, in combination with other known prognostic factors, and patients' progression-free survival (PFS) and overall survival (OS) was evaluated. RESULTS Sixty-nine patients were assessable. Plasma samples were collected after tumor biopsy (B), partial resection (PR), and complete resection (CR) for 22, 25, and 22 patients, respectively. At a median concentration of 5.37 pM (interquartile range 0.00-13.90 pM), hPG80 was detected in 48 (70%) patients (hPG80+). CR was associated with significant lower values of hPG80 levels: the median value was 0.7 versus 9.1 pM for PR (P = 0.02) and 8.3 pM for B (P = 0.004). The hPG80 detection rate was also significantly lower: 50% (CR) versus 72% (PR) versus 86% (B) (P = 0.005). The median follow-up was 39 months [22.4 months-not reached]. hPG80 post-operative detection was associated with numerically shorter PFS (6.4 versus 9.4 months, P = 0.13) and OS (14.5 versus 20.9 months, P = 0.11). In multivariate analysis, hPG80 was a prognostic factor for OS (P = 0.034). CONCLUSIONS Circulating hPG80 could serve as a new prognostic biomarker after surgery in patients with glioblastoma treated with radio-chemotherapy.

Abstract
Lakes and reservoirs have been identified as sentinels of climate change. Tonle Sap is the largest lake in both the Mekong Basin and Southeast Asia and because of the importance of its ecosystem, it is has been described as the "heart of the lower Mekong". Its seasonal cycle depends on the annual flood pulse governed by the flow of the Mekong River. This study provides an impact analysis of recent climatic events from El Niño 1997/1998 to El Niño 2015/2016 on surface storage variations in the Tonle Sap watershed determined by combining remotely sensed observations, multispectral images and radar altimetry from 1993 to 2017. The Lake's surface water volume variations are highly correlated with rainy season rainfall in the whole Mekong River Basin (R = 0.84) at interannual time-scale. Extreme droughts and floods can be observed when precipitation deficit and excess is recorded in both the Tonle Sap watershed and the Mekong River Basin during moderate to very strong El Niño/La Niña events (R = -0.70) enhanced by the Pacific Decadal Oscillation (R = -0.68). Indian and Western North Pacific Monsoons were identified as having almost equal influence. Below normal vegetation activity was observed during the first semester of 2016 due to the extreme drought in 2015.

Abstract
7688 Objective: To evaluate efficacy and toxicity of HDR BT in non operable endobronchial carcinoma from a retrospective multicentric study. Patients and Methods: Criteria for selection: non small cell carcinoma accessible to fiberoptic bronchoscopy, no extrabronchial extension on CT, contraindication to surgery and external radiation therapy (ERT). Statistical analysis: survival curves calculated with the Kaplan-Meier method and compared with the Logrank test; Cox model to evaluate in uni and multivariate analysis the impact on survival and complications of these parameters: location of tumor: lobar or segmental vs main stem bronchus, previous ERT vs no, total dose:= 30 Gy vs less, dose per fraction:= 5 Gy vs more, number of catheter(s):1 vs = 2. Results: Between 1991 and 2006, 226 patients from 9 radiotherapy departments were included. Main characteristics of tumors: squamous-cell histology: 96%, stage Tis: 60, T1: 153, T2: 9, Tx 4; lobar or segmental location: 91%. 51 patients (22.5%) had received ERT for previous lung cancer(s). Characteristics of HDR BT were: total dose = 30 Gy: 70%, dose per fraction = 5 Gy: 66%, 1 catheter: 46%. Dose was prescribed at 1 cm from the radius. Mean follow-up was 30.4 months (9- 116). Histologic evaluation was performed at 3 months in 137 patients. 92% had a complete response. 128 patients were died: intercurrent disease 45, local failure 35, complications 13. Two and 5-year survival: overall: 57%, 29%; specific (death of lung cancer) 81%, 56%; local- relapse free (LRF) 68%, 50%. Toxicity included 1.3% pneumothorax, hemoptysis 6.6% (5% fatal), bronchitis 20%. In univariate analysis: overall, specific and LRF survival were better for lobar or segmental location vs main stem bronchus (p=0.0001), overall and specific survival were higher with no previous ERT (p=0.006). In multivariate analysis, lobar or segmental location was associated with improved overall (p=0.0001) and LRF (p=0.003) survival. LRF survival was better in patients treated with = 2 catheters (p=0.007). No factor influence frequency of complications. Conclusion: This large retrospective study confirmed that HDRBT is efficient and safe in medically inoperable patients particulary with lobar or segmental endobronchial carcinoma. No significant financial relationships to disclose.
