Abstract

PURPOSE:The aim of this study was to determine the practice patterns and outcomes of intracranial germ cell tumors (IGCT) in adolescents and young adults according to different therapeutic approaches. METHODS AND MATERIALS:One-hundred twelve patients with IGCT aged 15 to 39 years were managed at either XX or the XY center from 1975 to 2015. The charts were retrospectively reviewed and data collected. RESULTS:Median duration of follow-up was 8.3 years. Ninety-four patients had germinomas, and 18 had nongerminomatous germ cell tumors (NGGCT). The primary disease sites were pineal gland (37 of 94 germinoma, 14 of 18 NGGCT) and suprasellar region (23 of 94 germinoma, 2 of 18 NGGCT). Eleven patients with germinoma (12%) and 2 patients with NGGCT (11%) had radiographic spinal metastases or positive lumbar cerebrospinal fluid cytology. Event-free survival (EFS) was 84% and overall survival (OS) was 90% at 10 years for germinoma; EFS was 71% and OS was 86% at 10 years for NGGCT. For patients with germinoma, 10-year EFS was 100% after craniospinal radiation therapy (CSRT) with chemotherapy (N = 10); 100% after whole-ventricular radiation therapy (WVRT), whole-brain radiation therapy (WBRT), or focal radiation therapy (FRT) with chemotherapy (N = 22); 90% after CSRT alone (N = 46); and 41% after WVRT, WBRT, or FRT alone (N = 16) (P < .0005). Ten-year OS was 100%, 100%, 90%, and 72%, respectively (P = .032). For patients with NGGCT, 10-year EFS was 80% after CSRT, WBRT, or WVRT plus chemotherapy (N = 10) versus 58% after FRT plus chemotherapy (N = 8) (P = .31); 10-year OS was 90% versus 58%, respectively (P = .16). CONCLUSIONS:We report excellent overall outcomes according to treatment approach in the largest study of IGCT in adolescents and young adults to our knowledge. EFS and OS were inferior after non-CSRT without chemotherapy in germinoma.

摘要

目的: 本研究的目的是根据不同的治疗方法确定青少年和年轻人颅内生殖细胞肿瘤 (IGCT) 的实践模式和结局。 方法和材料: 1975 年至 2015 年在XX或XY中心管理 112 例年龄 15 ~ 39 岁的IGCT患者。回顾性分析图表并收集数据。 结果: 中位随访时间为 8.3 年。94 例患者为生殖细胞瘤,18 例为非卵巢生殖细胞瘤 (NGGCT)。原发病部位为松果体 (94 例生殖细胞瘤中的 37 例,18 例NGGCT中的 14 例) 和鞍上区 (94 例生殖细胞瘤中的 23 例,18 例NGGCT中的 2 例)。11 例生殖细胞瘤患者 (12%) 和 2 例NGGCT患者 (11%) 影像学脊柱转移或腰椎脑脊液细胞学阳性。生殖细胞瘤 10 年无事件生存率 (EFS) 为 84%,总生存率 (OS) 为 90%; NGGCT 10 年EFS为 71%,OS为 86%。对于生殖细胞瘤患者,颅脊髓放射治疗 (CSRT) 加化疗 (N = 10) 后 10 年EFS为 100%; 全室放射治疗 (WVRT) 后 100%,全脑放射治疗 (WBRT) 或局灶放射治疗 (FRT) 联合化疗 (N = 22); 单纯CSRT后 90% (N = 46);WVRT、WBRT或FRT后 41% (N = 16) (P <.0005)。10 年OS分别为 100% 、 90% 和 72% (P = .032)。对于NGGCT患者,CSRT、WBRT或WVRT加化疗 (N = 10) 后 10 年EFS为 80%,而FRT加化疗 (N = 8) 后为 58% (P = .31); 10 年OS分别为 90% 和 58% (P = .16)。 结论: 据我们所知,在青少年和年轻人中最大的IGCT研究中,我们根据治疗方法报告了极好的总体结局。生殖细胞瘤非CSRT未化疗后EFS和OS较差。

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.
