Concordance of patient and caregiver reports in evaluating quality of life in patients with malignant gliomas and an assessment of caregiver burden.

Background: Given the neurocognitive impairment experienced by many patients with malignant gliomas, caregiver reports can be critical in assessing the quality of life (QOL) of these patients. In this study, we explored whether assessment of patient QOL by the primary caregiver shows concordance with the patient's self-reported QOL, and we quantified the burden faced by caregivers.

Methods: QOL of 45 patients was evaluated by both the patient and primary caregiver on 3 or more separate occasions using the Functional Assessment of Cancer Therapy-Brain (FACT-Br) instrument, and concordance between the 2 reports was evaluated.

A phase II trial of PTK787/ZK 222584 in recurrent or progressive radiation and surgery refractory meningiomas.

When surgery and radiation are no longer treatment options, salvage systemic therapy has been used for recurrent meningiomas with little compelling evidence to suggest effectiveness. Patients with surgery and radiation refractory recurrent meningiomas were treated with the oral multifunctional tyrosine kinase inhibitor PTK787/ZK 222584 (PTK787) at a dose of 500 mg twice a day. Each treatment cycle was 4 weeks with MRI done every 8 weeks.

Pemetrexed in the treatment of relapsed/refractory primary central nervous system lymphoma.

Background: Despite initial treatment with high-dose methotrexate-based regimens, many patients with primary central nervous system lymphoma (PCNSL) relapse and die from their disease. No standard of care exists at progression or relapse, but chemotherapy and in some cases radiation are usually used. Pemetrexed is a multitargeted antifolate, similar to methotrexate, but with a broader spectrum of activity.

Minimally invasive microendoscopy-assisted transforaminal lumbar interbody fusion with instrumentation.

Object: The authors have developed a novel technique for percutaneous fusion in which standard microendoscopic discectomy is modified. Based on data obtained in their cadaveric studies they considered that this minimally invasive interbody fusion could be safely implemented clinically. The authors describe their initial experience with a microendoscopic transforaminal lumbar interbody fusion (METLIF) technique, with regard to safety in the placement of percutaneous instrumentation, perioperative morbidity, and early postoperative results.
