Levetiracetam in a broad population of patients with refractory epilepsy: interim results of the international SKATE trial.

OBJECTIVE: To prospectively assess the safety and efficacy of levetiracetam in patients with uncontrolled focal epilepsy, in a common practice-based setting. PATIENTS AND METHODS: In this phase IV, open-label, 16-week community-based study, adult patients with focal seizures initially received levetiracetam 1,000 mg/day. Throughout the study, the dose was adjusted in increments of 1,000 mg (maximum 3,000 mg/day) to achieve seizure control and maintain tolerability. The outcome parameters were the percentage reduction in partial and total seizure frequency per week from historical baseline, global evaluation scale (GES), and adverse events (AE). RESULTS: Seven hundred and thirty-one patients were included in this analysis and 84.4% completed the study. The median percent reduction in all seizures was 47.8%, and 49.3% for all partial seizures. The 50% responder rate was 49%, and the seizure-free rate was 17.2% for all partial seizures. Approximately 60% of patients showed moderate to marked improvement on the GES. The majority of AE were of mild to moderate severity; the most commonly reported being asthenia, somnolence, headache, and dizziness. CONCLUSION: Levetiracetam is both efficacious and safe as an add-on therapy in patients with refractory epilepsy treated by clinicians in their daily practice.

Preoperative chemotherapy in primary operable breast cancer: results from the European Organization for Research and Treatment of Cancer trial 10902.

PURPOSE: To evaluate whether preoperative neoadjuvant chemotherapy in patients with primary operable breast cancer results in better overall survival (OS) and relapse-free survival rates and whether preoperative chemotherapy permits more breast-conserving surgery procedures than postoperative chemotherapy. PATIENTS AND METHODS: Six hundred ninety-eight breast cancer patients (T1c, T2, T3, T4b, N0 to 1, and M0) were enrolled onto a randomized phase III trial that compared four cycles of fluorouracil, epirubicin, and cyclophosphamide administered preoperatively versus the same regimen administered postoperatively (the first cycle administered within 36 hours after surgery). Patients were followed up for OS, progression-free survival (PFS), and locoregional recurrence (LRR). RESULTS: At a median follow-up of 56 months, there was no significant difference in terms of OS (hazards ratio, 1.16; P =.38), PFS (hazards ratio, 1.15; P =.27), and time to LRR (hazards ratio, 1.13; P =.61). Fifty-seven patients (23%) were downstaged by the preoperative chemotherapy, whereas 14 patients (18%) underwent mastectomy and not the planned breast-conserving therapy. CONCLUSION: The use of preoperative chemotherapy yields similar results in terms of PFS, OS, and locoregional control compared with conventional postoperative chemotherapy. In addition, preoperative chemotherapy enables more patients to be treated with breast-conserving surgery. Because preoperative chemotherapy does not improve disease outcome compared with postoperative chemotherapy, future trials should involve quality-of-life studies to investigate whether patients will benefit from this treatment modality.

Improved survival after one course of perioperative chemotherapy in early breast cancer patients. long-term results from the European Organization for Research and Treatment of Cancer (EORTC) Trial 10854.

The aim of this study was to examine whether one course of perioperative polychemotherapy yields better results in terms of survival, progression-free survival (PFS) and locoregional control than surgery alone in early stage breast cancer. From 1986 to 1991, 2795 patients with stage I/II breast cancer were randomised to receive either one perioperative course of an anthracycline-containing chemotherapeutic regimen within 36 h after surgery or surgery alone. Patients were followed-up for overall survival, PFS and locoregional recurrence. The median follow-up period at time of the analysis was 11 years. PFS and locoregional control were significantly better (P=0.025 and P=0.004, respectively) in the perioperative chemotherapy arm. Node-negative patients seemed to benefit most from the perioperative FAC. Patients who received perioperative chemotherapy and locoregional therapy alone had significantly better overall survival rates than patients who received locoregional therapy alone (P=0.004). Patients who received additional systemic therapy did not seem to benefit from one course of perioperative chemotherapy (P=0.65). One course of perioperative polychemotherapy does improve PFS and locoregional control in early stage breast cancers. This effect is still present after 11 years of follow-up.
