Methodological issues in designing and reporting health-related quality of life in cancer clinical trials: the challenge of brain cancer studies.
Health-related quality of life (HRQOL) and other types of patient-reported outcomes (PROs) are now important outcome measures in cancer clinical trials. A number of potentially less toxic drugs are available, and newer treatments can potentially offer cancer patients the possibility to be treated with less aggressive approaches, making PROs more critical in evaluating treatment effectiveness. ⋯ Robust methodology and accurate reporting of results are crucial to provide the scientific community and health care providers with a transparent message about the impact of a given drug or a new medical approach on patients' health status. This paper provides basic guidance on methodological issues to be addressed when designing and reporting HRQOL in clinical trials and presents examples of relevant brain cancer studies.

Cognitive outcome after awake surgery for tumors in language areas.
In surgery for tumors of the dominant hemisphere, the attention devoted to quality of resection and preservation of language function has not been accompanied by comparable interest in preservation of cognitive abilities which may affect quality of life. We studied 22 patients undergoing awake surgery for glioma removal in the language areas of the brain. Besides monitoring tumor variables (size, location, histology, edema), we used a multifaceted battery of tests to investigate mood, cognition, and language in an attempt to assess the burden of disease and treatment, and the relationships between these three dimensions. ⋯ No correlation was observed between scores for mood, cognition, and language function. A subset of patients with low-grade glioma was followed up for 3-6 months; although some improvement was observed they did not always regain their preoperative performance. In conclusion, we believe that cognitive assessment performed in conjunction with language testing is a necessary step in the global evaluation of brain tumor patients both before and after surgery.

Measuring clinical outcomes in neuro-oncology. A battery to evaluate low-grade gliomas (LGG).
We describe how a neuropsychological evaluation in patients with brain tumors should be performed, specifically in the case of low-grade gliomas. Neuropsychological examination is crucial before starting any treatment as well as during the follow-up, since it can improve neurosurgery techniques and reveal potential cognitive effects of chemotherapy and radiotherapy, besides planning rehabilitation. ⋯ Moreover, some tests can provide additional information about the evolution of the tumor. A careful, thorough examination improves quality of life.

The superiority of conservative resection and adjuvant radiation for craniopharyngiomas.
The purpose of this study is to evaluate the roles of resection extent and adjuvant radiation in the treatment of craniopharyngiomas. We reviewed the records of 122 patients ages 11-52 years who received primary treatment for craniopharyngioma between 1980 and 2009 at the University of California, San Francisco (UCSF). Primary endpoints were progression free survival (PFS) and overall survival (OS). ⋯ STR was associated with significantly shortened OS compared to STR + RT (p = 0.050) and trended to shorter OS compared to GTR (p = 0.066). GTR was associated with significantly greater risk of developing DI (56.3 vs. 13.3% with STR + XRT, p < 0.001) and panhypopituitarism (54.8 vs. 26.7% with STR + XRT, p = 0.014). In conclusion, for patients with craniopharyngioma, STR + RT may provide superior clinical outcome, achieving better disease control than STR and limiting side effects associated with aggressive surgical resection.
