RESUMO

OBJECTIVE: Chordomas are rare malignant bone tumors whose location in the skull base or spine, invasive surgical treatment, and accompanying adjuvant radiotherapy may all lead patients to experience poor quality of life (QOL). Limited research has been conducted on specific demographic and clinical factors associated with decreased QOL in chordoma survivors. Thus, the aim of the present study was to investigate several potential variables and their impact on specific QOL domains in these patients as well the frequencies of specific QOL challenges within these domains. METHODS: The Chordoma Foundation (CF) Survivorship Survey was electronically distributed to chordoma survivors subscribed to the CF Chordoma Connections forum. Survey questions assessed QOL in three domains: physical, emotional/cognitive, and social. The degree of impairment was assessed by grouping the participants into high- and low-challenge groups designated by having ≥ 5 or < 5 symptoms or challenges within a given QOL domain. Bivariate analysis of demographic and clinical characteristics between these groups was conducted using Fisher's exact test and the Mann-Whitney U-test. RESULTS: A total of 665 chordoma survivors at least partially completed the survey. On bivariate analysis, female sex was significantly associated with increased odds of significant emotional (p = 0.001) and social (p = 0.019) QOL burden. Younger survivors (age < 65 years) were significantly more likely to experience significant physical (p < 0.0001), emotional (p < 0.0001), and social (p < 0.0001) QOL burden. Skull base chordoma survivors had significantly higher emotional/cognitive QOL burden than spinal chordoma survivors (p = 0.022), while the converse was true for social QOL challenges (p = 0.0048). Survivors currently in treatment were significantly more likely to experience significant physical QOL challenges compared with survivors who completed their treatment > 10 years ago (p = 0.0074). Fear of cancer recurrence (FCR) was the most commonly reported emotional/cognitive QOL challenge (49.6%). Only 41% of the participants reported having their needs met for their physical QOL challenges as well as 25% for emotional/cognitive and 18% for social. CONCLUSIONS: The authors' findings suggest that younger survivors, female survivors, and survivors currently undergoing treatment for chordoma are at high risk for adverse QOL outcomes. Additionally, although nearly half of the participants reported a FCR, very few reported having adequate emotional/cognitive care. These findings may be useful in identifying specific groups of chordoma survivors vulnerable to QOL challenges and bring to light the need to expand care to meet the QOL needs for these patients.

RESUMO

BACKGROUND: Chordomas are a rare form of aggressive bone cancer and are associated with poor quality of life (QOL). The present study sought to characterize demographic and clinical characteristics associated with QOL in chordoma co-survivors (caregivers of patients with chordoma) and assess whether co-survivors access care for QOL challenges. METHODS: The Chordoma Foundation Survivorship Survey was electronically distributed to chordoma co-survivors. Survey questions assessed emotional/cognitive and social QOL, with significant QOL challenges being defined as experiencing ≥5 challenges within either of these domains. The Fisher exact test and Mann-Whitney U test were used to analyze bivariate associations between patient/caretaker characteristics and QOL challenges. RESULTS: Among the 229 respondents to our survey, nearly half (48.5%) reported a high number (≥5) of emotional/cognitive QOL challenges. Co-survivors younger than 65 years were significantly more likely to experience a high number of emotional/cognitive QOL challenges (P < 0.0001), whereas co-survivors >10 years past the end of treatment were significantly less likely to experience a high number of emotional/cognitive QOL challenges (P = 0.012). When asked about access to resources, a lack of knowledge of resources to address their emotional/cognitive and social QOL issues (34% and 35%, respectively) was the most common response. CONCLUSIONS: Our findings suggest that younger co-survivors are at high risk for adverse emotional QOL outcomes. In addition, more than one third of co-survivors did not know about resources to address their QOL issues. Our study may help guide organizational efforts to provide care and support to patients with chordoma and their loved ones.

RESUMO

OBJECTIVE: Pineoblastomas (PBLs) are rare high-grade tumors treated variably with surgery and/or radiation. The role of surgical extent of resection and radiotherapy (RT) in adult PBL remains unclear. We queried the Surveillance, Epidemiology, and End Results (SEER) database to assess these variables' effects on overall survival (OS) in adult PBL. METHODS: The SEER (1975-2016) database was queried for adult patients with diagnosis of PBL (ICD-0-3: 9362/3). Variables extracted included age, sex, race, geographical region, extent of tumor resection, RT, chemotherapy (CT), and OS data. Comparisons were performed with the χ2 test for categorical variables, Cox proportional hazards models to assess the association of clinical variables on OS, and Kaplan-Meier curves were generated. RESULTS: A total of 201 patients with PBL were identified with mean age 40.0 years (interquartile range 27.0-51.0) and most patients being male (53%) and Caucasian (77%). 101 (50%) patients received RT, and gross total resection was achieved in 83 (41%). Age stratification by decade revealed statistically significant poorer OS in patients aged ≥70 years. In bivariate analysis, RT with or without surgery was associated with improved 5-year OS compared with no RT (77.3% vs. 63.2%, P = 0.020). In multivariate analysis, age was a poor prognostic factor for OS (P < 0.001) and RT did appear to improve survival (P = 0.020). Extent of surgical resection was not significantly associated with improved survival. CONCLUSIONS: In adult patients with PBL, RT may offer an OS benefit irrespective of surgery or extent of surgical resection. Patients ≥70 years of age are associated with poorer OS.

RESUMO

OBJECTIVE: In recent years, frailty indices such as the 11- and 5-factor modified frailty indices (mFI-11 and mFI-5), American Society of Anesthesiologists (ASA) physical status classification, and Charlson Comorbidity Index (CCI) have been shown to be effective predictors of various postoperative outcomes in neurosurgical patients. The Hospital Frailty Risk Score (HFRS) is a well-validated tool for assessing frailty; however, its utility has not been evaluated in intracranial tumor surgery. In the present study, the authors investigated the accuracy of the HFRS in predicting outcomes following intracranial tumor resection and compared its utility to those of other validated frailty indices. METHODS: A retrospective analysis was conducted using an intracranial tumor patient database at a single institution. Patients eligible for study inclusion were those who had undergone resection for an intracranial tumor between January 1, 2017, and December 31, 2019. ICD-10 codes were used to identify HFRS components and subsequently calculate risk scores. In addition to several postoperative variables, ASA class, CCI, and mFI-11 and mFI-5 scores were determined for each patient. Model discrimination was assessed using the area under the receiver operating characteristic curve (AUROC), and the DeLong test was used to assess for significant differences between AUROCs. Multivariate models for continuous outcomes were constructed using linear regression, whereas logistic regression models were used for categorical outcomes. RESULTS: A total of 2518 intracranial tumor patients (mean age 55.3 ± 15.1 years, 53.4% female, 70.4% White) were included in this study. The HFRS had a statistically significant greater AUROC than ASA status, CCI, mFI-11, and mFI-5 for postoperative complications, high hospital charges, nonroutine discharge, and 90-day readmission. In the multivariate analysis, the HFRS was significantly and independently associated with postoperative complications (OR 1.14, p < 0.0001), hospital length of stay (coefficient = 0.50, p < 0.0001), high hospital charges (coefficient = 1917.49, p < 0.0001), nonroutine discharge (OR 1.14, p < 0.0001), and 90-day readmission (OR 1.06, p < 0.0001). CONCLUSIONS: The study findings suggest that the HFRS is an effective predictor of postoperative outcomes in intracranial tumor patients and more effectively predicts adverse outcomes than other frailty indices. The HFRS may serve as an important tool for reducing patient morbidity and mortality in intracranial tumor surgery.

RESUMO

OBJECTIVE: The safety and effectiveness of task-sharing (TS) in neurosurgery, delegating clinical roles to non-neurosurgeons, is not well understood. This study evaluated an ongoing TS model in the Philippines, where neurosurgical workforce deficits are compounded with a large neurotrauma burden. METHODS: Medical records from emergency neurosurgical admissions to 2 hospitals were reviewed (January 2015-June 2018): Bicol Medical Center (BMC), a government hospital in which emergency neurosurgery is chiefly performed by general surgery residents (TS providers), and Mother Seton Hospital, an adjacent private hospital where neurosurgery consultants are the primary surgeons. Univariable and multivariable linear and logistic regression compared provider-associated outcomes. RESULTS: Of 214 emergency neurosurgery operations, TS providers performed 95 and neurosurgeons, 119. TS patients were more often male (88.4% vs. 73.1%; P = 0.007), younger (mean age, 27.6 vs. 50.5 years; P < 0.001), and had experienced road traffic accidents (69.1% vs. 31.4%; P < 0.001). There were no significant differences between Glasgow Coma Scale (GCS) scores on admission. Provider type was not associated with mortality (neurosurgeons, 20.2%; TS, 17.9%; P = 0.68), reoperation, or pneumonia. No significant differences were observed for GCS improvement between admission and discharge or in-hospital GCS improvement, including or excluding inpatient deaths. TS patients had shorter lengths of stay (17.3 days vs. 24.4 days; coefficient, -6.67; 95% confidence interval, -13.01 to -0.34; P < 0.05) and were more likely to undergo tracheostomy (odds ratio, 3.1; 95% confidence interval, 1.30-7.40; P = 0.01). CONCLUSIONS: This study, one of the first to examine outcomes of neurosurgical TS, shows that a strategic TS model for emergency neurosurgery produces comparable outcomes to the local neurosurgeons.

RESUMO

MicroRNA deregulation is a consistent feature of glioblastoma, yet the biological effect of each single gene is generally modest, and therapeutically negligible. Here we describe a module of microRNAs, constituted by miR-124, miR-128 and miR-137, which are co-expressed during neuronal differentiation and simultaneously lost in gliomagenesis. Each one of these miRs targets several transcriptional regulators, including the oncogenic chromatin repressors EZH2, BMI1 and LSD1, which are functionally interdependent and involved in glioblastoma recurrence after therapeutic chemoradiation. Synchronizing the expression of these three microRNAs in a gene therapy approach displays significant anticancer synergism, abrogates this epigenetic-mediated, multi-protein tumor survival mechanism and results in a 5-fold increase in survival when combined with chemotherapy in murine glioblastoma models. These transgenic microRNA clusters display intercellular propagation in vivo, via extracellular vesicles, extending their biological effect throughout the whole tumor. Our results support the rationale and feasibility of combinatorial microRNA strategies for anticancer therapies.

RESUMO

BACKGROUND: Prostate cancer (PCa) is the most common malignancy in Mexican men. Serum prostate-specific antigen (PSA) is the usual noninvasive biomarker used for its detection. Its low specificity can increase the number of unnecessary prostate biopsies and the incidence of unpleasant complications for patients. The androgen-receptor gene (AR-CAG) repeat length and the percentage of promoter methylation (PPM) of genes glutathione-S-transferase P1 (GSTP1) and Ras association domain family 1 isoform A (RASSF1A) improve PCa detection. As an option for noninvasive assessment, we evaluated a combined analysis of all these biomarkers. PATIENTS AND METHODS: A total of 186 patients scheduled for biopsy were included in the present study. PSA and AR-CAG repeats were analyzed in blood samples. The PPM of GSTP1 and RASSF1A genes was estimated in prostate tissue and urinary sediment cells (USCs) and plasma DNA using quantitative methylation-specific polymerase chain reaction. The predictive values for PCa and benign prostatic hyperplasia (BPH), logistic regression analysis, receiver operating characteristic curve, and decision curve analysis were used to assess the differential diagnosis. RESULTS: Statistically significant differences between PCa and BPH patients were observed for all biomarkers, with higher positive and negative predictive values when all biomarkers were included in the analysis, attaining USC values of 89.2% and 78.0%, respectively. The differential diagnosis accuracy of PSA (area under the curve, 0.59) increased to 0.70 and 0.68, respectively, when the combined analysis of PPM of RASSF1Aplasma or GSTP1AUSC and AR-CAG repeats was performed. Decision curve analysis showed the utility of the combined analysis to decrease the number of unnecessary biopsies. CONCLUSION: The results showed that combined analysis of the proposed biomarkers in plasma and USCs significantly increased the confidence for the differential diagnosis for PCa and BPH. This noninvasive practice might help in the early detection of PCa and patient follow-up, avoiding to some extent unnecessary prostate biopsies.

RESUMO

Objetivos: Establecer la prevalencia de uso de la citología del cuello uterino e identificar los factores que determinan la asistencia a este examen. Métodos Estudio de corte transversal en voluntarias de un programa de prevención de cáncer de cuello uterino realizado en Mogotes, Colombia. Se calcularon razones de prevalencia (RP). La variable dependiente fue el antecedente de asistencia a citología. Se recolectaron características sociodemográficas, clínicas, familiares y de hábitos. Resultados La prevalencia de asistencia previa a citología fue 67,3 por ciento. A mayor edad de la mujer aumentaba la probabilidad de tener una citología anterior. El uso de métodos de planificación familiar que requerían control (RP: 1,4; IC95 por ciento: 1,2-1,7) y la residencia rural (RP: 0,9; IC95 por ciento: 0,8-1,0) también fueron factores que determinaron su utilización. Conclusiones Estos datos confirman que vivir en zonas rurales está asociado con una menor oportunidad de la mujer para acceder al examen citológico.


Objectives: Determining the prevalence of Pap smear use and identifying the factors associated with Pap test performance. Methods A cross-sectional study was carried out on volunteer women recruited from a local programme for detecting cervical cancer in Mogotes, Colombia. Prevalence ratios (PR) were calculated. Papanicolau smear use was the outcome being measured. Information about demographic characteristics, clinical factors, history of cancer in the family, lifestyle factors and using birth control methods was collected. Results Pap smear use prevalence was 67,3 percent. Age group, using birth control methods (PR:1,4; 95 percentCI:1,2-1,7) and living in rural settings (PR:0,9; 95 percentCI:0,8-1,0) were the factors associated with Pap test performance. Conclusions This data suggests that living in rural settings is associated with decreased opportunities for performing Pap tests.

RESUMO

Se estudiaron 39 pacientes con carcinoma prostático en etapas clínicas C y D de la clasificación de Jewett Whitemore, en quienes se consideró indicado el tratamiento hormonal. Se utilizaron estrógenos conjugados naturales (ECN) a dosis de 1.25 mg tres veces al día, y se determinaron las concentraciones de testosterona (TS) y antígeno prostático específico (PSA) sérico antes y tres meses después del tratamiento. La TS disminuyó significativamente en 94.4 por ciento de los pacientes, 86.1 por ciento a menos de 1 ng y 8.3 por ciento a un nivel entre 1.1 y 1.5 ng. El PSA se abatió a cifras normales en 16 pacientes (44.4 por ciento), y en cinco más (13.8 por ciento) se ubicó entre 5 y 10 ng. Once pacientes (30.5 por ciento) mostraron reacción, pero ésta se conservó en más de 20 ng. Cuatro pacientes (11.1 por ciento) no mostraron disminución del PSA con el tratamiento empleado, y en dos de ellos las concentraciones de TS no reaccionaron durante el tratamiento. Los ECN son otra alternativa económica y eficaz para el tratamiento del carcinoma prostático avanzado. La determinación de TS y PSA basal y a los tres meses permite evaluar la reacción
