BACKGROUND/AIM:An increasing number of patients undergo surgical treatment for metastatic spinal cord compression (MSCC). However, the possible role of sex as an independent predictor of long-term survival has not been studied. This study aimed to examine whether sex is associated with long-term survival after surgical treatment in patients with MSCC. PATIENTS AND METHODS:A total of 110 patients were operated on for MSCC from 2005 through 2006. The relation between sex and overall survival was investigated. The follow-up period was 10 years. RESULTS:Survival time was significantly longer for women compared to men (mean±SD: 29±5.2 vs. 14±3.6 month (p=0.01). With adjusted analysis, this difference remained statistically significant. After adjusting for specific primary tumor type and time since surgery, the hazard-ratio of 10-year survival for men compared to women was 1.47 (95% confidence intervaI=1.01-2.18, p=0.048). CONCLUSION:These findings indicate that sex is associated with long-term survival in patients treated for MSCC.
背景/目的: 越来越多的患者接受手术治疗转移性脊髓压迫 (MSCC)。然而，性别作为长期生存的独立预测因子的可能作用尚未研究。本研究旨在探讨性别是否与MSCC患者手术治疗后的长期生存相关。 患者和方法: 从 2005 年到 2006 年，共有 110 例患者接受了MSCC手术。研究了性别与总生存期之间的关系。随访时间为 10 年。 结果: 与男性相比，女性的生存时间显著更长 (平均值 ± SD: 29 ± 5.2 vs. 14 ± 3.6 个月 (p = 0.01)。通过调整分析，这种差异仍然具有统计学意义。在调整了特定的原发肿瘤类型和自手术以来的时间后，男性与女性相比的 10 年生存率的风险比为 1.47 (95% 置信区间intervaI = 1.01-2.18，p = 0.048)。 结论: 这些研究结果表明，性别与MSCC治疗患者的长期生存相关。
METHODS:OBJECTIVE:Large inoperable sacral chordomas show unsatisfactory local control rates even when treated with high dose proton therapy (PT). The aim of this study is assessing feasibility and reporting early results of patients treated with PT and concomitant hyperthermia (HT). METHODS: :Patients had histologically proven unresectable sacral chordomas and received 70 Gy (relative biological effectiveness) in 2.5 Gy fractions with concomitant weekly HT. Toxicity was assessed according to CTCAE_v4. A volumetric tumor response analysis was performed. RESULTS: :Five patients were treated with the combined approach. Median baseline tumor volume was 735 cc (range, 369-1142). All patients completed PT and received a median of 5 HT sessions (range, 2-6). Median follow-up was 18 months (range, 9-26). The volumetric analysis showed an objective response of all tumors (median shrinkage 46%; range, 9-72). All patients experienced acute Grade 2-3 local pain. One patient presented with a late Grade 3 iliac fracture. CONCLUSION:Combining PT and HT in large inoperable sacral chordomas is feasible and causes acceptable toxicity. Volumetric analysis shows promising early results, warranting confirmation in the framework of a prospective trial. ADVANCES IN KNOWLEDGE: :This is an encouraging first report of the feasibility and early results of concomitant HT and PT in treating inoperable sacral chordoma.
METHODS:BACKGROUND:National guidelines recommend screening and treatment for cancer-related bone disease and continued monitoring of bone-modifying agents. It is unclear whether a standardized screening tool is utilized to identify eligible patients and ensure appropriate supportive care is implemented. The purpose of this study was to evaluate current prescribing practices and optimize management of bone-modifying agents. METHODS:A retrospective chart review was performed to identify patients who received hormone deprivation therapy or had bone metastases through Hematology/Oncology or Urology clinics from 1 November 2016 to 31 October 2017. The primary endpoints of this study were the incidence of completed baseline dual-energy X-ray absorptiometry (DEXA) scan for patients on hormone deprivation therapy and percent of patients started on a bone-modifying agent for the prevention of skeletal-related events secondary to bone metastasis. Secondary endpoints included percent of patients with dental examinations prior to initiation, adequate calcium and vitamin D supplementation, incidence of osteonecrosis of the jaw or flu-like symptoms and education, and percent of bisphosphonate doses appropriately adjusted based on renal function. RESULTS:A total of 375 patients were assessed for baseline DEXA scans and bone-modifying therapy. Of the 226 patients on hormone deprivation therapy, 111 (49%) patients were appropriately screened with a DEXA scan prior to initiation of hormone deprivation therapy. Among the 149 patients with bone metastases, only 94 (63.1%) patients were started on a bone-modifying agent. CONCLUSIONS:Opportunities have been identified to optimize management of patients with cancer-related bone disease. Implementation of standardized tools may increase the rate of appropriate screening and initiation of bone-modifying therapy when warranted.
METHODS:PURPOSE:Low skeletal muscle mass has been associated with poor prognosis in patients with advanced lung cancer. However, little is known about the relationship between skeletal muscle mass and overall survival in patients with bone metastases from lung cancer. The objective of the present study was to evaluate the prognostic value of low trunk muscle mass in predicting overall survival in these patients. METHODS:The data from 198 patients who were diagnosed with bone metastases from lung cancer from April 2009 to May 2017 were retrospectively reviewed. The areas of the psoas and paravertebral muscles were measured at the level of the third lumbar vertebra on computed tomography scans taken at the time nearest to the diagnosis of bone metastasis. Muscle area was evaluated for male and female cohorts separately using different cutoff points. Cox proportional hazards analysis was performed to evaluate the factors independently associated with overall survival. RESULTS:The overall survival of patients in the lowest quartile for psoas muscle area or paravertebral muscle area was significantly shorter than that of patients above the 25th percentile for muscle area (p < 0.001). Multivariate analyses showed that paravertebral muscle mass (hazard ratio, 1.73; 95% confidence interval, 1.17-2.56; p = 0.006), epidermal growth factor receptor-targeted therapy, and performance status were independent prognostic factors. CONCLUSIONS:Low paravertebral muscle mass was associated with shorter survival, independently of known prognostic factors.
