Aggressive surgical management of spinal metastatic disease can provide improvement of neurological function and significant pain relief. However, there is limited literature analyzing such management as is pertains to individual histopathology of the primary tumor, which may be linked to overall prognosis for the patient. In this study, clinical outcomes were reviewed for patients undergoing spinal surgery for metastatic breast cancer. Respective review was done to identify all patients with breast cancer over an eight-year period at a major cancer center and then to select those with symptomatic spinal metastatic disease who underwent spinal surgery. Pre-and postoperative pain levels (visual analog scale [VAS]), analgesic medication usage, and modifed Frankel grade scores were compared on all patients who underwent surgery. Univariate and multivariate analyses were used to assess risks for complications. A total of 16,977 patients were diagnosed with breast cancer, and 479 patients (2.8%) were diagnosed with spinal metastases from breast cancer. Of these patients, 87 patients (18%) underwent 125 spinal surgeries. Of the 76 patients (87%) who were ambulatory preoperatively, the majority (98%) were still ambulatory.Of the 11 patients (13%) who were nonambulatory preoperatively, four patients were alive at 3 months postoperatively, three of which (75%) regained ambulation. The preoperative median VAS of six was significantly reduced to a median score of two at the time of discharge and at 3, 6, and 12 months postoperatively (P < 0.001 for all time points). A total of 39% of patients experienced complications; 87% were early (within 30 days of surgery), and 13% were late. Early major surgical complications were significantly greater when five or more levels were instrumented. In patients with spinal metastases specifically from breast cancer, aggressive surgical management provides significant pain relief and preservation or improvement of neurological function with an acceptably low rate of complications.

The histology of the primary tumor in metastatic spine disease plays an important role in its treatment and prognosis. However, there is paucity in the literature of histology-specific analysis of spinal metastases. In this study, prognostic variables were reviewed for patients who underwent surgery for breast metastases to the spinal column. Respective chart review was done to first identify all patients with breast cancer over an 8-year period at a major cancer center and then to select all those with symptomatic metastatic disease to the spine who underwent spinal surgery. Univariate and multivariate analyses were used to assess several prognostic variables. Presence of visceral metastases, multiplicity of bony lesions, presence of estrogen receptors (ER), and segment of spine (cervical, thoracic, lumbar, sacral) in which metastases arose were compared with patient survival. Eighty-seven patients underwent 125 spinal surgeries. Those with estrogen receptor (ER) positivity had a longer median survival after surgery compared to those with estrogen receptor negativity. Patients with cervical location of metastasis had a shorter median survival compared with those having metastases in other areas of the spine. The presence of visceral metastases or a multiplicity of bony lesions did not have prognostic value. In patients with spinal metastases from breast cancer, aggressive surgical management may be an option for providing significant pain relief and preservation/improvement of neurological function. Interestingly, in patients undergoing such surgery, cervical location of metastasis is a negative prognostic variable, and ER-positivity is associated with better survival, while presence of visceral or multiple bony lesions does not significantly alter survival.

The results indicate that patients harboring a GBM that contains a large cyst survive longer and have a longer time to recurrence than those who lack such a cyst. This is the first such observation in the literature.

Object. The object of this study was to describe the experience of combining awake craniotomy techniques with high-field (1.5 T) intraoperative MRI (iMRI) for tumors adjacent to eloquent cortex.Methods. From a prospective database the authors obtained and evaluated the records of all patients who had undergone awake craniotomy procedures with cortical and subcortical mapping in the iMRI suite. The integration of these two modalities was assessed with respect to safety, operative times, workflow, extent of resection (EOR), and neurological outcome.Results. Between February 2010 and December 2011, 42 awake craniotomy procedures using iMRI were performed in 41 patients for the removal of intraaxial tumors. There were 31 left-sided and 11 right-sided tumors. In half of the cases (21 [50%] of 42), the patient was kept awake for both motor and speech mapping. The mean duration of surgery overall was 7.3 hours (range 4.0-13.9 hours). The median EOR overall was 90%, and gross-total resection (EOR ≥ 95%) was achieved in 17 cases (40.5%). After viewing the first MR images after initial resection, further resection was performed in 17 cases (40.5%); the mean EOR in these cases increased from 56% to 67% after further resection. No deficits were observed preoperatively in 33 cases (78.5%), and worsening neurological deficits were noted immediately after surgery in 11 cases (26.2%). At 1 month after surgery, however, worsened neurological function was observed in only 1 case (2.3%).Conclusions. There was a learning curve with regard to patient positioning and setup times, although it did not adversely affect patient outcomes. Awake craniotomy can be safely performed in a high-field (1.5 T) iMRI suite to maximize tumor resection in eloquent brain areas with an acceptable morbidity profile at 1 month.

RESUMO -Objetivo: Análise de 52 pacientes pediátricos com trauma de crânio (TCE) assistidos em Unidade de Terapia Intensiva, considerando fatores epidemiológicos do trauma, manifestações clínicas, aspectos tomográficos, variações hemodinâmicas e opções de tratamento da hipertensão intracraniana; avaliar a utilização da monitorização da pressão intracraniana (PIC). Método: Estudo retrospectivo de 52 pacientes com TCE e 17 destes submetidos a monitorização da PIC. Resultado: Houve predominância masculina e a média de idade foi 7,75 anos. Atropelamento foi a principal causa (38,5% dos casos). Encontramos 21,2% dos pacientes com hipotensão arterial. Foram classificados como TCE grave 67,3% dos pacientes. Tivemos graduação tomográfica de Marshall tipo I em 19,2%, II em 65,4%, III em 3,8%, IV em 3,8% e V em 7,7%. Apresentaram crise convulsiva 25%. Foram submetidos a monitorização da PIC 32,7%. A taxa de mortalidade foi 11,5%. O maior valor pressórico ocorreu no segundo dia em 58,8%. Conclusão: O prognóstico se relacionou com a severidade do trauma, hipotensão arterial, graduação tomográfica de Marshall tipo III e IV e altos valores de PIC. A monitorização da PIC permite facilidades no diagnóstico e tratamento da hipertensão intracraniana. PALAVRAS-CHAVE: trauma de crânio, criança, pressão intaracraniana, monitorização. Analysis of 52 patients with head trauma assisted at pediatric intensive care unit: considerations about intracranial pressure monitoringABSTRACT -Objectives: Analysis of 52 pediatric patients with head trauma assisted at Intensive Care Unit; to present considerations about epidemiologic factors of trauma, clinical presentation, tomografic aspects, hemodynamic changes and treatment options of intracranial hypertension; to present considerations about the intracranial pressure (ICP) monitoring. Method: Retrospective study involving 52 patients with head trauma and 17 patients submitted to a ICP monitoring. Results: We found a male predominance, mean age 7.75 years-old, main cause was run over (38.5%); 21.2% patients presentd arterial hypotension; 67.3% were considered severe head trauma. According to Marshall tomografic grading we had 19.2% type I, 65.4% type II, 3.8% type III, 3.8% type IV and 7.7% type V. Seizures occurred in 25% children ICP monitoring was made in 32.7% of all patients. Mortality rate was 11.5%. In 58% the maximum ICP level occured at the second day of trauma. Conclusion: Prognosis was related to severity of trauma, arterial hypotension, Marshall's tomografic gradind III and IV and ICP high values. The ICP monitoring was considered useful to allow the identification and treatment of intracranial hypertension.
