ReviewCognition and resective surgery for diffuse infiltrative glioma: an overview.
Compared to classical oncological outcome measures such as time to progression and survival, the importance of cognitive functioning in patients with diffuse infiltrative brain tumors has only recently been recognized. Apart from the relatively low incidence and the invariably fatal outcome of gliomas, the general assumption that cognitive assessment is time-consuming and burdensome contributes to this notion. ⋯ The impact of other factors affecting cognition in glioma patients such as direct tumor effects, radiotherapy and chemotherapy, and medical treatment, including anti-epileptic drugs and steroids, have been studied more extensively. The purpose of this paper is to provide an overview of cognition in patients with diffuse infiltrative gliomas and the impact of resective surgery as well as other tumor and treatment-related factors.

Cognitive outcome as part and parcel of clinical outcome in brain tumor surgery.
Although validated tools (neuropsychological tests, patient reported outcomes, mood and psychological profile) were first introduced many years ago in clinical practice, the impact of the tumor itself on patient cognition has not been extensively studied. Furthermore, while outcome research is evolving in an attempt to adapt the use of different tools to the preoperative and postoperative phases, the standard guidelines for evaluating outcome after brain surgery, by neurological examination and complication assessment, are frequently neglected in the current literature. This article attempts to provide an appraisal of the evidence for the impact of surgical treatment on cognitive function of brain tumor patients within the context of general outcome.

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.

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.

ReviewEmerging techniques in the minimally invasive treatment and management of thoracic spine tumors.
Over the past decade, the development and refinement of minimally invasive spine surgery techniques has lead to procedures with the potential to minimize iatrogenic and post-operative sequelae that may occur during the surgical treatment of various pathologies. In a similar manner, parallel advances in other current treatment technologies have led to the development of other minimally invasive treatments of spinal malignancies. These advances include percutaneous techniques for vertebral reconstruction, including vertebroplasty and kyphoplasty, the development of safe and effective spinal radiosurgery, and minimal-access spinal surgical procedures that allow surgeons to safely decompress and reconstruct the anterior spinal column. ⋯ The author's describe how these emerging treatment options are significantly expanding the options open to clinicians in the treatment of thoracic spinal column malignancies. Specific illustrative case examples are provided. The development of these techniques has the potential to improve clinical outcomes, limit surgical morbidity, and also improve the safety and efficiency of treatment pathways.
