Multicenter randomized phase III trial of Epirubicin plus Paclitaxel vs Epirubicin followed by Paclitaxel in metastatic breast cancer patients: focus on cardiac safety

The aim of the study was to evaluate cardiac safety of two different schedules of Epirubicin and Paclitaxel in advanced breast cancer patients enrolled into a multicenter randomized phase III trial. Patients received Epirubicin 90 mgm(-2) plus Paclitaxel 200 mgm(-2) (3-h infusion) on day 1 every 3 weeks for eight courses (arm A), or Epirubicin 120 mgm(-2) on day 1 every 3 weeks for four courses followed by four courses of Paclitaxel 250 mgm(-2) on day 1 every 3 weeks (arm B). Left ventricular ejection fraction was evaluated by bidimesional echocardiography at baseline, after four and eight courses of chemotherapy and every 4 months during follow-up. Baseline median left ventricular ejection fraction was 60% in arm A and 65% in arm B; after four courses, figures were 57 and 60%, respectively. After eight courses, the median left ventricular ejection fraction in arm A declined to 50% while no further reduction was detected in arm B by adding four courses of high-dose Paclitaxel. Seven episodes of congestive heart failure were observed during treatment in arm A. Present monitoring demonstrated that the risk of congestive heart failure or impairment in the cardiac function correlated only with the cumulative dose of Epirubicin; no impact on cardiotoxicity can be attributed to high-dose Paclitaxel

Multi-centre phase II clinical trial of yttrium-90 resin microspheres alone in unresectable, chemotherapy refractory colorectal liver metastases

Background:This multi-centre phase II clinical trial is the first prospective evaluation of radioembolisation of patients with colorectal liver metastases (mCRC) who failed previous oxaliplatin-and irinotecan-based systemic chemotherapy regimens.Methods:Eligible patients had adequate hepatic, haemopoietic and renal function, and an absence of major hepatic vascular anomalies and hepato-pulmonary shunting. Gastroduodenal and right gastric arteries were embolised before hepatic arterial administration of yttrium-90 resin microspheres (median activity, 1.7 GBq; range, 0.9-2.2).Results:Of 50 eligible patients, 38 (76%) had received 654 lines of chemotherapy. Most presented with synchronous disease (72%), <4 hepatic metastases (58%), 25-50% replacement of total liver volume (60%) and bilateral spread (70%). Early and intermediate (<48 h) WHO G1-2 adverse events (mostly fever and pain) were observed in 16 and 22% of patients respectively. Two died due to renal failure at 40 days or liver failure at 60 days respectively. By intention-to-treat analysis using Response Evaluation Criteria in Solid Tumours, 1 patient (2%) had a complete response, 11 (22%) partial response, 12 (24%) stable disease, 22 (44%) progressive disease; 4 (8%) were non-evaluable. Median overall survival was 12.6 months (95% CI, 7.0-18.3); 2-year survival was 19.6%.Conclusion: Radioembolisation produced meaningful response and disease stabilisation in patients with advanced, unresectable and chemorefractory mCRC. \ua9 2010 Cancer Research UK All rights reserved

Hepatic Arterial Infusion with Oxaliplatin and 5-FU/Folinic Acid for Advanced Biliary Tract Cancer: A Phase II Study.

Background Effective and tolerable chemotherapy with gemcitabine and cisplatin for advanced biliary tract cancer (BTC) has been established recently. However, overall prognosis is still poor, and additional therapeutic approaches are needed for patients with locally advanced, irresectable and/or pretreated tumors. Hepatic arterial infusion (HAI) of chemotherapy represents a safe and well-established treatment modality, but data on its use in patients with BTC are still sparse. Methods Patients with irresectable BTC predominant to the liver were included in a prospective, open phase II study investigating HAI provided through interventionally implanted port catheters. Intraarterial chemotherapy consisted of biweekly oxaliplatin (O) 85 mg/m2 and folinic acid (F) 170 mg/m2 with 5-FU (F) 600 mg/m2. Results Between 2004 and 2010, 37 patients were enrolled. A total of 432 cycles of HAI were applied with a median of 9 (range 1–46) cycles. Objective response rate was 16 %, and tumor control was achieved in 24 of 37 (65 %) patients. Median progression-free survival was 6.5 months (range 0.5–26.0; 95 % CI 4.3–8.7), median overall survival was 13.5 (range 0.9–50.7; 95 % CI 11.1–15.9) months. The most frequent adverse event was sensory neuropathy grade 1/2 in 10/14 patients. Conclusions Using a minimal invasive technique, repetitive HAI with OFF is feasible and results in clinically relevant tumor control with low toxicity in patients with liver predominant advanced BTC
