In recent decades, frame-based (FBB) and frame-less stereotactic brain biopsy (FLB) have played a crucial role in defining the diagnosis and management of expanding intracranial lesions in critical areas. During the same period, there have been significant advances in diagnostic imaging, a shift in surgical strategies towards extensive resection in gliomas and new molecular classification of brain tumors. Taking these advances into account, we have evaluated whether significant changes have occurred over the last sixteen years of our clinical practice in terms of frequency, indications, target selection, and the histologic results of stereotactic brain biopsy (SBB) procedures.. We analyzed a series of 421 SBB cases treated between January 2002 and June 2017 in three major neurosurgical institutes in Rome, serving a total of 1.5 million people. Within this series, 94.8% of patients underwent FBB, while, more recently, FLB was performed in 5.2% of cases. The entire period under consideration, running from 2002 to 2017, has been further stratified into four-year time-frames (2002-2005, 2006-2009, 2010-2013, 2014-2017) for the purpose of analysis.. The diagnostic yield was 97%. Final diagnoses revealed tumors in 90% of cases and non-neoplastic masses in 7%, while 3% of cases were not conclusive. The morbidity rate was 3% (12 cases) and mortality was 0.7% (3 cases). Intra-operative frozen sections were made in 78% of biopsies. In our three institutes, the number of SBBs decreased steadily throughout the time-frames under consideration. We have also observed a statistically significant reduction in biopsy procedures in lobar lesions, while those performed on the basal ganglia increased and the number of SBBs of multiple masses and lesions of the corpus callosum remained stable. Primary central nervous system diagnosis of lymphomas (PCNSL) was the sole diagnosis whose incidence increased significantly.. Over the last sixteen years, we have witnessed a significant decrease in SBB procedures and a modification in target selection and histologic results. Despite the significant evolution of neuroimaging, an accurate non-invasive diagnosis of intracranial expanding lesions has not yet been achieved. Furthermore, the most recent WHO classification of brain tumors (2016), which incorporates molecular and morphological features, has boosted the need for molecular processing of tissue samples in all expanding brain lesions. For these reasons, it is likely that SBBs will continue to be performed in specific cases, playing a significant role in diagnostic confirmation by providing tissue samples, so as to better assess the biology and the prognosis of cerebral lesions, as well as their sensitivity to standard radio-chemotherapy or to new molecular target therapies.

The goal of neurosurgery for cerebral intraparenchymal neoplasms of the eloquent areas is maximal resection with the preservation of normal functions, and minimizing operative risk and postoperative morbidity. Currently, modern technological advances in neuroradiological tools, neuronavigation, and intraoperative magnetic resonance imaging (MRI) have produced great improvements in postoperative morbidity after the surgery of cerebral eloquent areas. The integration of preoperative functional MRI (fMRI), intraoperative MRI (volumetric and diffusion tensor imaging [DTI]), and neuronavigation, defined as "functional neuronavigation" has improved the intraoperative detection of the eloquent areas.. We reviewed 142 patients operated between 2004 and 2010 for intraparenchymal neoplasms involving or close to one or more major white matter tracts (corticospinal tract [CST], arcuate fasciculus [AF], optic radiation). All the patients underwent neurosurgery in a BrainSUITE equipped with a 1.5 T MR scanner and were preoperatively studied with fMRI and DTI for tractography for surgical planning. The patients underwent MRI and DTI during surgery after dural opening, after the gross total resection close to the white matter tracts, and at the end of the procedure. We evaluated the impact of fMRI on surgical planning and on the selection of the entry point on the cortical surface. We also evaluated the impact of preoperative and intraoperative DTI, in order to modify the surgical approach, to define the borders of resection, and to correlate this modality with subcortical neurophysiological monitoring. We evaluated the impact of the preoperative fMRI by intraoperative neurophysiological monitoring, performing "neuronavigational" brain mapping, following its data to localize the previously elicited areas after brain shift correction by intraoperative MRI.. The mean age of the 142 patients (89 M/53 F) was 59.1 years and the lesion involved the CST in 66 patients (57 %), the language pathways in 24 (21 %), and the optic radiations in 25 (22 %). The integration of tractographic data into the volumetric dataset for neuronavigation was technically possible in all cases. In all patients intraoperative DTI demonstrated a shift of the bundle position caused by the surgical procedure; its dislocation was both outward and inward in the range of +6 mm and -2 mm.. We found a high concordance between fMRI/DTI and intraoperative brain mapping; their combination improves the sensitivity of each technique, reducing pitfalls and so defining "functional neuronavigation", increasing the definition of eloquent areas and also reducing the time of surgery.

Despite aggressive multimodality treatment the prognosis of patients with primary brain tumors (BT) remains poor. At present, there are no data about the role of palliative home-care services and their impact on quality of care. We report the results of a pilot project of palliative home care for BT patients started in 2000 in the National Cancer Institute Regina Elena of Rome. We report also the result of a cost/effectiveness analysis utilizing administrative data on re-hospitalization rate in the last two months of life.. Since October 2000 until December 2009, 572 patients have been followed by our home care staff. Among 394 patients who died, 276 (70%) were followed at home until death. A cost/effectiveness analysis was carried out evaluating the rehospitalization rate in the last 2 months of life in a subgroup of patients (group 1 assisted at home, 72 patients; group 2 not assisted at home, 71). The number of hospital readmission in the last 2 months of life, and length and cost of hospitalization were retrospectively analyzed from hospital discharge records.. Hospitalization rate of group 1 (16.7%) was lower than group 2 (38%) (95% CI: 0.18-0.65, p = 0.001). Costs of hospitalization also differed substantially: 517 Euros (95% CI: 512-522) in group 1 vs 24, 076 Euros (95%: 24,040-24,112 Euros) in group 2.. Home-care may represent an alternative to in-hospital care for the management of brain tumor patients and may improve the end-of-life quality of care.

The mortality of a cohort of 2310 male workers who obtained a licence to handle pesticides in the period 1973-1979 in the province of Rome was investigated. The cohort contributed 26,846 person-years of exposure. The vital status of the cohort was determined up to the end of 1988. The causes of death of the 207 who had died were ascertained from death certificates. Standardized mortality ratios (SMR) were computed using both the provincial and the national mortality rates. The two methods yielded very similar results. Using the national rates, the SMR for all causes was 56 (95% confidence interval (CI) : 45.3-59.8), for cardiovascular diseases 47 (95% CI : 37.1-59.1), and for all cancers 72 (95% CI : 57.8-89.3). A statistically significant excess was noted for brain cancer (SMR = 270, 95% CI : 108.6-556.9). In addition, the cohort experienced statistically significant lower lung cancer mortality (SMR = 57, 95% CI : 35.6-80.0).
