Improved irritability, mood, and quality of life following introduction of perampanel as late adjunctive treatment for epilepsy.

OBJECTIVE: The objective of this study was to evaluate the efficacy and tolerability of perampanel (PER) in late adjunctive treatment of focal epilepsy. We assessed outcomes 1) according to patients' clinical profiles and the broad mechanism of action (MoA) of concomitant antiepileptic drugs (AEDs) and 2) the effects of PER on adverse events, irritability, mood, and quality of life (QOL). METHODS: Consecutive patients commenced on PER at two epilepsy centers in Melbourne, Australia were identified. A nested cohort underwent detailed prospective assessment, while the remainder were retrospectively analyzed. Six- and 12-month efficacy endpoints were at least a 50% reduction in seizure frequency (responders) and complete seizure freedom. The prospective cohort underwent standardized validated questionnaires at 0, 1, 3, 6, and 12 months using the modified semi-structured seizure interview (SSI), Liverpool Adverse Events Profile (LAEP), Quality of Life in Epilepsy-Patient-Weighted (QOLIE-10-P), Neurological Disorders Depression Inventory Epilepsy (NDDI-E), and an Irritability Questionnaire. RESULTS: One hundred sixty patients were followed for a median of 6 months: the mean number of prior AEDs was 6, 99% had drug-resistant epilepsy, and 72% had never experienced a prior seizure-free period of at least 6 months (=continuously refractory epilepsy). Perampanel was associated with responder and seizure freedom rates of 30.6% and 9.4% at 6 months and 19.4% and 4.4% (5.6% adjusted for the titration period) at 12 months. Having "continuously refractory epilepsy" was associated with a reduced likelihood of seizure freedom at 6 months (5% vs. 30%; p = 0.001) and 12 months (3% vs. 13%; p = 0.058). Quality of Life in Epilepsy-Patient-Weighted, irritability, and NDDI-E showed mean improvement at 6 months from baseline. SIGNIFICANCE: Even when used as late add-on adjunctive therapy in patients with highly refractory focal epilepsy, PER can result in 12-month seizure freedom of 5.6%. The likelihood of seizure freedom was associated with prior "continuous medication refractoriness". Six months after introduction of PER patients reported improved mood, QOL, and decreased irritability.

Outcomes following resection of non-small cell lung cancer in octogenarians.

BACKGROUND: The treatment of choice for early stage non-small cell lung cancer (NSCLC) is surgical resection. Little is known about the short- and long-term outcomes among very elderly patients. We sought to determine predictors of short- and long-term survival among octogenarians undergoing curative-intent resection for NSCLC in Victoria, Australia. METHODS: We retrospectively reviewed data from all patients aged ≥80 years who underwent curative-intent resection for NSCLC over 12 years (January 2005-December 2016) across five tertiary centres. We examined effect of age, stage of disease, extent of surgery and lung function on short- and long-term survival. RESULTS: Two hundred patients aged ≥80 years underwent curative-intent resections. Mortality at 30 and 120 days was 2.9% and 5.9%, respectively. Increased early mortality was observed among those ≥83 years, at 30 days (6.8% versus 0.8%, P = 0.044) and 120 days (12.2% versus 2.3%, P = 0.0096). Early mortality was highest among patients ≥83 years requiring lobectomy, compared to sub-lobar resection at 120 days (17% versus 3.8%, P = 0.019). Long-term survival was predicted by age and stage of disease. Among patients with Stage I disease aged <83 years, lobectomy was associated with superior 5-year survival, compared to sub-lobar resection (83% versus 61%, P = 0.02). CONCLUSION: In carefully selected elderly patients undergoing curative-intent resection of early stage NSCLC, both short- and long-term outcomes appear consistent with younger historical cohorts. Early mortality was associated with lobectomy in those with advanced age. Older patients undergoing lobectomy appeared to be at highest risk for early mortality, while younger patients with Stage I disease undergoing at least lobectomy appear to have the best long-term survival.
