Abstract

The effectiveness of bevacizumab monotherapy in elderly patients with non-squamous non-small cell lung cancer (NSCLC) is unclear. The efficacy of the combinations for elderly patients was explored. Untreated patients (≥75 years; performance status 0-1) with stage IIIB, IV, or recurrent non-squamous NSCLC were included. Patients with epidermal growth factor receptor (EGFR) mutation or anaplastic lymphoma kinase (ALK) gene rearrangements were eligible even if they received tyrosine kinase inhibitors. Patients were randomized 1:1 to receive docetaxel (50 mg/m2) (DB) or pemetrexed (500 mg/m2) (PB) with bevacizumab (15 m/kg). The primary endpoint was progression-free survival (PFS). Treatment was administered every 3 weeks until disease progression or unacceptable toxicity. Overall, 103 patients (DB: n=51; PB: n=52) were enrolled. In the DB and PB arms, median ages [range] were 78 [75-88] and 79 [75-94] years, respectively; median PFS were 6.1 and 4.6 months, respectively [hazard ratio (HR), 1.03; 95% confidence interval (CI), 0.66-1.61]; and response rates were 43%, and 40%, respectively (P=0.840). Grade ≥3 leukopenia, neutropenia, and fatigue incidences were significantly higher in the DB arm. Febrile neutropenia incidence did not...Continue Reading

Aortic Aneurysm

An aortic aneurysm is the weakening and bulging of the blood vessel wall in the aorta. This causes dilatation of the aorta, which is usually asymptomatic but carries the risk of rupture and hemorrhage. Find the latest research on aortic aneurysms here.

Cardiac Aneurysm

Aneurysm refers to a bulge of the wall or lining of a vessel commonly occurring in the blood vessels at the base of the septum or within the aorta. In the heart, it usually arises from a patch of weakened tissue in a ventricular wall, which swells into a bubble filled with blood. Discover the latest research on cardiac aneurysm here.
