Prognostic impact of preoperative platelets to lymphocytes ratio (PLR) on survival for oesophageal and junctional carcinoma treated with neoadjuvant chemotherapy: A retrospective monocentric study on 153 patients.

This study was designed to investigate the prognostic impact of elevated platelet to lymphocyte ratio (PLR) on survival for oesophageal and junctional adenocarcinoma (OJA) treated with neoadjuvant chemotherapy in a curative intent. From 2004 to 2014, 153 consecutive patients with OJA were included. PLR was measured at first diagnosis. Receiver Operating Characteristic curve analysis was performed to determinate PLR threshold. Cox multivariate model was used to assess correlation between PLR and survival. Cut-off value for PLR was 192, which identified 2 groups of patients: low (n = 122) and high PLR value (n = 31). Both groups were comparable by patient (age, sex, ASA score) and tumour characteristics (differentiation, TNM stage, location). Five year overall survival (OS) was 65%. OS and DFS were reduced in the high PLR group: p = 0.019 and p = 0.016, respectively. PLR was associated with increased recurrence (54.8% vs. 35.2%, p = 0.046) and cancer-related death (41.9% vs. 23.8%, p = 0.043) rates. On multivariate analysis, elevated PLR was associated with decreased DFS (HR = 2.85, 95%CI = 1.54-5.26, p = 0.001) and OS (HR = 2.47, 95%CI = 1.21-5.01, p = 0.012). This study demonstrates that elevated PLR is associated with poor OS and DFS for OJA treated with a curative intent and has the potential to be a useful prognostic biomarker for treatment planning.

1000 Port-A-Cath ® placements by subclavian vein approach: single surgeon experience.

INTRODUCTION: Totally implantable venous access ports are widely used for the administration of chemotherapy in patients with cancer. Although there are several approaches to implantation, here we describe Port-A-Cath(®) (PAC) placement by percutaneous puncture of the subclavian vein with ultrasonographic guidance. PATIENTS AND METHODS: Data on our vascular access service were collected prospectively from June 2004. This service included port-a-caths and Hickman lines. Once 1000 consecutive port-a-caths(®) had been reached the study was closed and data analysed for the port-a-caths(®) alone. The left subclavian vein was the preferred site for venous access, with the right subclavian and jugular veins being the alternative choices if the initial approach failed. Patients were followed up in the short-term, and all the procedures were carried out by a single surgeon at each one of two institutions. RESULTS: Venous access by PAC was established in 100 % of the 1,000 cases. Of the 952 patients where the left subclavian vein was chosen for the first attempt of puncture, the success rate of PAC placement was 95 % (n = 904). Pneumothorax occurred in 12 patients (1.2 %), and a wound haematoma occurred in 4 (0.4 %) out of the total 1,000 patients. No infections were recorded during the immediate post-operative period but only in the long-term post-operative use with 8 patients requiring removal of the PAC due to infection following administration of chemotherapy. CONCLUSION: This is a very large series of PAC placement with an ultrasound-guided approach for left subclavian vein and X-ray confirmation, performed by a single surgeon, demonstrating both the safety and effectiveness of the procedure.
