BACKGROUND/AIM:Estimating survival is important for treatment personalization in patients with metastatic cancer. In this study, we aimed to develop a survival score for patients irradiated for bone metastases from colorectal cancer. PATIENTS AND METHODS:Eleven factors were retrospectively analyzed in 25 patients, including age, gender, Eastern Cooperative Oncology Group performance score, tumor site, time between diagnosis of colorectal cancer and irradiation, visceral or other bone metastases, type and number of irradiated sites, upfront surgery and previous systemic treatment. RESULTS:On multivariate analysis, performance score (p=0.005) and previous systemic treatment (p=0.007) were significantly associated with survival and used for the score. One point (performance score 0-1 or no previous systemic treatment) or 0 points (performance score ≥2 or previous systemic treatment) were assigned resulting in 0, 1 or 2 points. Six-month survival rates of these groups were 0%, 64% and 100%, respectively. CONCLUSION:This new survival score can support physicians during personalization of treatment for patients with bone metastases from colorectal cancer.


背景/目的: 估计生存期对于转移性癌症患者的个性化治疗是重要的。在这项研究中,我们的目的是制定一个生存评分的患者接受放疗的骨转移结直肠癌。 患者与方法: 回顾性分析 25 例患者的 11 个因素,包括年龄、性别、美国东部肿瘤协作组绩效评分、肿瘤部位、结直肠癌确诊距照射时间、内脏或其他骨转移,照射部位的类型和数量,前期手术和既往全身治疗。 结果: 在多变量分析中,性能评分 (p = 0.005) 和既往系统治疗 (p = 0.007) 与生存显著相关,并用于评分。分配 1 分 (绩效评分 0-1 或既往未进行全身治疗) 或 0 分 (绩效评分 ≥ 2 或既往进行全身治疗),得到 0 、 1 或 2 分。这些组的 6 个月生存率分别为 0% 、 64% 和 100%。 结论: 这个新的生存评分可以支持医生对结直肠癌骨转移患者进行个性化治疗。

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.
