RATIONALE:Chondromyxoid fibroma (CMF) is a rare form of benign bone tumor and easily misdiagnosed as fibrosarcoma. Hence, to explore the clinical manifestations, diagnostic tests, and therapeutic procedures for temporal bone cartilage myxoid fibroma, it is important to optimize patient treatment and avoid overtreatment. Previous research has discussed cases of CMF, but this paper presents a systematic, complete, and comprehensive introduction of this disease based on this case and related literature. PATIENT CONCERNS:A 52-year-old male patient presented with pain in his right ear for 2 years and hearing loss in his right ear with tinnitus for 1 year. The patient had a history of hypertension for 9 years and it was well-controlled. DIAGNOSIS:A computed tomography (CT) scan of the temporal bone showed an expansive growth on the right temporal bone plate and tympanic plate, presenting as a cloud-like ground glass opaque shadow involving the temporom and ibular joint, middle skull base, and small auditory bones. A magnetic resonance imaging (MRI) of the temporal bone showed a large and irregular soft tissue mass shadow on the right temporal bone plate. The right temporal bone plate was occupied by the lesion, consistent with a bone origin. From the results of the imaging examination of the patient, a lesion occupying the temporal bone in the right ear and mastoiditis in the right middle ear was initially diagnosed. INTERVENTIONS:Right ear temporal bone tumor resection and abdominal fat extraction were conducted. OUTCOMES:Postoperative pathological results demonstrated myxoid fibroma of the temporal bone cartilage. No recurrence or severe complications were observed in 8 months of follow-up. LESSONS:A finding of myxoid fibroma of the temporal bone cartilage is rare in the clinic. The growth of such tumors is slow. The temporal bone CT and inner ear MRI were helpful in diagnosis. Surgery was the principal treatment.
基本原理: 软骨黏液样纤维瘤 (CMF) 是一种罕见的良性骨肿瘤，容易误诊为纤维肉瘤。因此，为了探讨颞骨软骨黏液样纤维瘤的临床表现、诊断试验和治疗程序，优化患者治疗和避免过度治疗非常重要。以往的研究对CMF的病例进行了讨论，但本文结合该病例及相关文献对该病进行了系统、完整、全面的介绍。 患者顾虑: 1 例 5 2 岁男性患者，表现为右耳疼痛 2 年，右耳听力下降伴耳鸣 1 年。患者有高血压病史 9 年，控制良好。 诊断: 颞骨计算机断层扫描 (CT) 显示右侧颞骨板和鼓室板有膨胀性生长，表现为云状磨玻璃不透明阴影，累及颞部和小骨关节、中颅base和小听骨。颞骨磁共振成像 (MRI) 显示右侧颞骨板上有一大块不规则的软组织肿块影。右侧颞骨板被病灶占据，符合骨起源。从患者的影像学检查结果，初步诊断为右耳颞骨占位性病变，右中耳乳突炎。 干预措施: 行右耳颞骨肿瘤切除和腹部脂肪取出术。 结果: 术后病理结果显示为颞骨软骨黏液样纤维瘤。随访 8 个月，无复发及严重并发症。 教训: 颞骨软骨黏液样纤维瘤在临床上很少见。这类肿瘤生长缓慢。颞骨CT和内耳MRI有助于诊断。手术是主要的治疗方法。
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.
