Since 1995, lobar resection became the standard of care for medically fit patients with early stage lung cancer. This was based on the results of a single randomized trial comparing lobectomy and sublobar resection (SLR) in stage I lung cancer conducted by the lung cancer study group between 1982 and 1988. The conclusions of the study included a statistically significant tripling in loco-regional recurrence (LR) after limited resection but no difference between the two arms of the trial in systemic recurrence...

BACKGROUND: Stereotactic radiosurgery (SRS) is used to manage patients with Cushing's disease (CD) who have failed surgical/medical management. As many patients with recurrent/persistent CD lack an identifiable adenoma on neuro-imaging, whole-sellar SRS has been increasingly employed. We therefore sought to define the outcomes of patients undergoing whole-sellar SRS. METHODS: An international, multicenter, retrospective cohort-design was used to define clinical/endocrine outcomes for patients undergoing whole-sellar SRS for CD...

Patients who undergo surgical resection of brain metastases are at significant risk of cavity local recurrence without additional radiation therapy. Postoperative stereotactic radiosurgery (SRS) is a method of focal treatment to the cavity to maximize local control while minimizing the risk of neurocognitive detriment associated with whole brain radiation therapy. Recently published randomized trials have demonstrated the benefit of postoperative SRS in terms of cavity tumor control and preserving neurocognition...

Background: Patient-reported outcomes (PRO) represent an important measure of cancer therapy effect. For patients with metastatic epidural spinal cord compression (MESCC), hybrid therapy using separation surgery and stereotactic radiosurgery preserves neurologic function and provides tumor control. There is currently a paucity of data reporting PRO after such combined modality therapy for MESCC. Delineation of hybrid surgery-radiosurgery therapy effect on PRO validates the hybrid approach as an effective therapy resulting in meaningful symptom relief...

Objective: The current opinion among neurosurgeons regarding the selection between microvascular decompression (MVD) and gamma knife radiosurgery for trigeminal neuralgia is not based on clear evidence. In this meta-analysis, we have attempted to synthesize the findings of the prospective trials comparing the efficacy and complications of the two procedures as primary treatment modality for medically refractory trigeminal neuralgia. Materials and Methods: The authors performed a systematic review of PubMed for manuscripts comparing the efficacy or complications of MVD and stereotactic radiosurgery for medically refractory trigeminal neuralgia...

Actual indications for surgery in tuberculosis are limited to obtaining a diagnosis, acquiring tissue for culture studies, treating hydrocephalus, aspiring a brain abscess, and reducing intracranial pressure in patients with multiple tuberculomas. Tuberculosis-related movement disorders are usually treated pharmacologically. We report on a child affected by post-tubercular generalized dystonia, who progressed to status dystonicus (SD) and underwent stereotactic bilateral pallidotomy. After surgery, SD resolved, and drugs were rapidly tapered...

A few study has proven that about 90% of local control rates might be benefit from stereotactic body radiotherapy (SBRT) for patients with medically inoperable stage I non-small cell lung cancer (NSCLC), it is reported SBRT associated overall survival and tumor specific survival is comparable with those treated with surgery. SBRT has been accepted as the first line treatment for inoperable patients with peripheral located stage I NSCLC. However, the role of SBRT in centrally located lesions is controversial for potential toxic effects from the adjacent anatomical structure...

Studies showed that physical exercise decreases the risk of developing Parkinson's disease (PD) as slowing its progression. During aerobic training, nitric oxide (NO) increases in the substantia nigra pars compacta (SNpc) of individuals with PD. However, no study has evaluated the effects of exercise on peripheral NO levels and its modulatory effects on cardiovascular dysfunctions of subjects with PD. Trained (T) or sedentary (S) animals underwent stereotactic surgery for bilateral 6-hydroxydopamine (6-OHDA) or vehicle microinfusion (Sham group)...

In patients undergoing surgical resection of brain metastases, the risk of local recurrence remains high. Adjuvant whole brain radiation therapy (WBRT) can reduce the risk of local relapse but fails to improve overall survival. At two tertiary care centers in Germany, a retrospective study was performed to evaluate the role of hypofractionated stereotactic radiotherapy (HFSRT) in patients with brain metastases after surgical resection. In particular, need for salvage treatment, for example, WBRT, surgery, or stereotactic radiosurgery (SRS), was evaluated...
