The importance of surgery in scalp angiosarcomas.

ABSTRACT: BACKGROUND:Scalp angiosarcomas (SA) are rare, representing <1% of soft tissue sarcomas. The optimal management of these tumors is unknown, with management based on small case series. We sought to assess the impact of different therapies on overall survival (OS), the practice patterns nationally, and identify factors associated with OS for non-metastatic scalp angiosarcomas. METHODS:A prospectively maintained database was used to identify non-metastatic scalp angiosarcomas who received some form of definitive therapy. Logistics regression, Kaplan-Meier, and Cox proportional-hazard models were utilized. RESULTS:A total of 589 patients met study entry criteria with a median follow-up of 4.2 years. The majority (482 patients, 81.8%) had upfront definitive resection and an additional 317 patients (65.8%) received postoperative radiation. Of the 107 patients who didn't have surgery, the majority (65 patients, 60.7%) received definitive radiation and 42 patients (39.3%) received radiation and chemotherapy. One-year and five-year survival estimates for patients not receiving definitive surgery were 68.0% (95%CI: 57.5-76.4) and 18.0% (95%CI: 10.2-27.5) respectively compared to 78.2% (95%CI: 74.0-81.9) and 34.1% (95%CI: 28.9-39.3) for patients receiving definitive surgery (p?

Project description:Scalp electroencephalography (EEG) and intraoperative electrocorticography (ECoG) are routinely used in the evaluation of magnetic resonance imaging-negative temporal lobe epilepsy (TLE) undergoing standard anterior temporal lobectomy with amygdalohippocampectomy (ATL), but the utility of interictal epileptiform discharge (IED) identification and its role in outcome are poorly defined.To determine whether the following are associated with surgical outcomes in patients with magnetic resonance imaging-negative TLE who underwent standard ATL: (1) unilateral-only IEDs on preoperative scalp EEG; (2) complete resection of tissue generating IEDs on ECoG; (3) complete resection of opioid-induced IEDs recorded on ECoG; and (4) location of IEDs recorded on ECoG.Data were gathered through retrospective medical record review at a tertiary referral center. Adult and pediatric patients with TLE who underwent standard ATL between January 1, 1990, and October 15, 2010, were considered for inclusion. Inclusion criteria were magnetic resonance imaging-negative TLE, standard ECoG performed at the time of surgery, and a minimum follow-up of 12 months. Univariate analysis was performed using log-rank time-to-event analysis. Variables reaching significance with log-rank testing were further analyzed using Cox proportional hazards.Excellent or nonexcellent outcome at time of last follow-up. An excellent outcome was defined as Engel class I and a nonexcellent outcome as Engel classes II through IV.Eighty-seven patients met inclusion criteria, with 48 (55%) achieving an excellent outcome following ATL. Unilateral IEDs on scalp EEG (P?=?.001) and complete resection of brain regions generating IEDs on baseline intraoperative ECoG (P?=?.02) were associated with excellent outcomes in univariate analysis. Both were associated with excellent outcomes when analyzed with Cox proportional hazards (unilateral-only IEDs, relative risk?=?0.31 [95% CI, 0.16-0.64]; complete resection of IEDs on baseline ECoG, relative risk?=?0.39 [95% CI, 0.20-0.76]). Overall, 25 of 35 patients (71%) with both unilateral-only IEDs and complete resection of baseline ECoG IEDs had an excellent outcome.Unilateral-only IEDs on preoperative scalp EEG and complete resection of IEDs on baseline ECoG are associated with better outcomes following standard ATL in magnetic resonance imaging-negative TLE. Prospective evaluation is needed to clarify the use of ECoG in tailoring temporal lobectomy.

Project description:Genetic variants in relevant genes coexisting with MRI lesions in children with drug-resistant epilepsy (DRE) can negatively influence epilepsy surgery outcomes. Still, presurgical evaluation does not include genetic diagnostics routinely. Here, we report our presurgical evaluation algorithm that includes routine genetic testing. We analyzed retrospectively the data of 68 children with DRE operated at a mean age of 7.8 years (IQR: 8.1 years) at our center. In 49 children, genetic test results were available. We identified 21 gene variants (ACMG III: n = 7, ACMG IV: n = 2, ACMG V: n = 12) in 19 patients (45.2%) in the genes TSC1, TSC2, MECP2, DEPDC5, HUWE1, GRIN1, ASH1I, TRIO, KIF5C, CDON, ANKD11, TGFBR2, ATN1, COL4A1, JAK2, KCNQ2, ATP1A2, and GLI3 by whole-exome sequencing as well as deletions and duplications by array CGH in six patients. While the results did not change the surgery indication, they supported counseling with respect to postoperative chance of seizure freedom and weaning of antiseizure medication (ASM). The presence of genetic findings leads to the postoperative retention of at least one ASM. In our cohort, the International League against Epilepsy (ILAE) seizure outcome did not differ between patients with and without abnormal genetic findings. However, in the 7/68 patients with an unsatisfactory ILAE seizure outcome IV or V 12 months postsurgery, 2 had an abnormal or suspicious genetic finding as a putative explanation for persisting seizures postsurgery, and 3 had received palliative surgery including one TSC patient. This study highlights the importance of genetic testing in children with DRE to address putative underlying germline variants as genetic epilepsy causes or predisposing factors that guide patient and/or parent counseling on a case-by-case with respect to their individual chance of postoperative seizure freedom and ASM weaning.

Project description:ImportanceDiversity in academic surgery is lacking, particularly among positions of leadership.ObjectiveTo evaluate trends among racial/ethnical minority groups stratified by gender along the surgical pipeline, as well as in surgical leadership.Design, setting, and participantsThis cross-sectional and longitudinal analysis assessed US surgical faculty census data obtained from the Association of American Medical Colleges faculty roster in the Faculty Administrative Management Online User System database. Surgical faculty members captured in census data from December 31, 2013, to December 31, 2019, were included in the analysis. Faculty were identified from the surgery category of the faculty roster, which includes general surgeons and subspecialists, neurosurgeons, and urologists.Main outcomes and measuresGender and race/ethnicity were obtained for surgical faculty stratified by rank. Descriptive statistics with annual percentage of change in representation are reported based on faculty rank.ResultsA total of 15 653 US surgical faculty, including 3876 women (24.8%), were included in the data set for 2019. Female faculty from racial/ethnic minority groups experienced an increase in representation at instructor and assistant and associate professorship appointments, with a more favorable trajectory than male faculty from racial/ethnic minority groups across nearly all ranks. White faculty maintain most leadership positions as full professors (3105 of 3997 [77.7%]) and chairs (294 of 380 [77.4%]). The greatest magnitude of underrepresentation along the surgical pipeline has been among Black (106 of 3997 [2.7%]) and Hispanic/Latinx (176 of 3997 [4.4%]) full professors. Among full professors, although Black and Hispanic/Latinx male representation increased modestly (annual change, 0.07% and 0.10%, respectively), Black female representation remained constant (annual change, 0.00004%) and Hispanic/Latinx female representation decreased (annual change, -0.16%). Overall Hispanic/Latinx (20 of 380 [5.3%]) and Black (13 of 380 [3.4%]) representation as chairs has not changed, with only 1 Black and 1 Hispanic/Latinx woman ascending to chair from 2013 to 2019.Conclusions and relevanceA disproportionately small number of faculty from minority groups obtain leadership positions in academic surgery. Intersectionality may leave female members of racial/ethnic minority groups more disadvantaged than their male colleagues in achieving leadership positions. These findings highlight the urgency to diversify surgical leadership.
