Purpose: To evaluate the activity and tolerance of vinorelbine (VRL) in combination with gemcitabine (GEM) in pre-treated patients with refractory ovarian cancer. Patients and methods: Seventeen patients with ovarian cancer who had disease progression after a carboplatin and taxane front-line regimen were treated with VRL 30 mg/m 2 IV over 10 min followed by GEM 1,200 mg/m 2 IV over 30 min on days 1 and 15 of each 28 days cycle. Chemotherapy was given in a initial prospective plan of six cycles, unless disease progression or unacceptable toxicity was seen, giving more cycles as consolidation therapy in the case of CR, PR or SD. The median age of patients was 67 years old, and the performance status (WHO) was 1 for 13 and 2 for 4 patients. The treatment was second-line for 11 (65%) and >third-line for 6 (35%) patients. Results: One complete and one partial response were observed (ORR:11%). Stable disease was seen in 4 (24%) patients and progressive disease in 11 (65%). The median time to tumor progression was 4 months (range 2-11), and the median survival has not yet been reached. Myelotoxicity was rare. Grade 1 neutropenia was observed just in one patient and grade 2/3 anemia in four patients (24%). Thrombocytopenia was absent. Non-hematologic toxicity was also predictable and easily manageable. Conclusion: The vinorelbine plus gemcitabine combination at the present doses and schedule is a safe but ineffective regimen, and therefore, is not recommended as second-line and beyond treatment in patients with refractory ovarian cancer. © 2010 Springer-Verlag.

Purpose: The purpose of this study is to evaluate the fluctuations of coagulation parameters during cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (HIPEC) and confirm beyond doubt that epidural anaesthesia is safe with this type of operations. Materials and methods: This is a prospective clinical study of consecutive patients who had cytoreductive surgery and HIPEC. An epidural catheter was inserted into all patients. Peripheral venous blood samples in specific time points of the procedure were tested for complete blood count, prothrombin time (PT), activated partial thromboplastin time (aPTT), international normalised ratio (INR), fibrinogen, D-dimer, and expression of the GpIIb/IIIa platelet receptor. Results: A total of 51 consecutive patients were included in this study. The initial mean (SD) platelet count decreased significantly to a mean of 250.6 (105.4) 109/L (p < 0.001). Fibrinogen levels decreased to 295.9 (127.4) mg/dL (p = 0.009). D-dimer levels increased to 5.3 (3.1) mg/dL (p < 0.001). APTT increased from 30.8 (5.8) s to 35.1 (4.6). The mean INR increased significantly to 1.5 (0.5) (p < 0.001). The total number of GpIIb/IIIa platelet receptors showed no significant variation throughout the measurements and was 72603.2 before HIPEC, 80772.4 during, and 77432.1 after. All the parameters examined, despite significant fluctuations remained in levels that would permit perioperative epidural analgesia. No related complications were recorded. Conclusion: Our results support the belief that epidural analgesia is a safe option in cytoreductive surgery and HIPEC despite certain intraoperative fluctuations in coagulation parameters. It is of major importance to regulate any abnormalities observed during surgery. There are no available data regarding the occurrence of coagulopathy in the post-operative period. © 2015 Taylor & Francis. Source

Cytoreductive surgery with HIPEC has provided a chance for long-term survival in selected patients. However, perioperative management remains a challenge for the anesthesiology team. The aim of this study was to evaluate the changes in hemodynamic parameters during hyperthermic intraperitoneal chemotherapy (HIPEC) using the FloTrac/ Vigileo system. Forty-one consecutive patients undergoing cytoreductive surgery and HIPEC were enrolled. Heart rate (HR), esophageal temperature, and cardiac output (CO) steadily increased until the end of HIPEC. In the first half of HIPEC, systolic blood pressure (SBP) and central venous pressure (CVP) increased whereas systemic vascular resistance (SVR) decreased; SVR stabilized in the second half. Diastolic blood pressure (DBP), mean arterial pressure (MAP), and stroke volume (SV) showed no significant variation. Male gender was related to increased CVP, CO, and SV, and decreased SVR; age >55 years was related to increased SBP, and peritoneal cancer index (PCI) was correlated with HR, DBP, and SV. PCI >14 was associated with increased HR and decreased DBP and MAP. American Society of Anesthesiologists score >1 was related to decreased CO and SV. Patients undergoing HIPEC develop a hyperdynamic circulatory state because of the increased temperature, characterized by a steady decrease in SVR and continuous increase in HR and CO. FloTrac/Vigileo system may provide an easy-to-handle, noninvasive monitoring tool. Source
