Abstract

Background: Chondrosarcoma is regarded as the second most common primary bone malignancy following osteosarcoma. Objectives: The present study aimed at determining the epidemiology, incidence, and survival rate of chondrosarcoma in the Iranian population, according to the Iran National Cancer Registry (INCR). Methods: In an epidemiological study, patients with limb chondrosarcoma were evaluated based on INCR data between 2008 and 2015. Data included patients’ demographic characteristics, date of diagnosis, location of the tumor, patient’s survival, and type of tumor based on the International Classification of Diseases for Oncology (ICD-O-3; first revision, third edition) were collected and analyzed. Results: Out of 732 enrolled patients, 425 patients (58.06%) were male and 307 (41.94%) were female with a mean age of 44.08 (SD = 19.31) and 45.06 (SD = 18.72), respectively. Age-standardized incidence rates (ASIR) were 1.73 and 1.27 per 1 million person-years for males and females, respectively. Conventional chondrosarcoma was the most common subtype with ASIR 1.28 and constituted 84.7% of patients with chondrosarcoma. About 71.03% of all Chondrosarcoma patients (70.35% of males and 71.99% of females) were between 20 to 59 years old. The 1-, 3-, 5-, and 7-year survival rates of patients were 0.87, 0.73, 0.57, and 0.47, respectively. Also, the mean survival time was 6.12 years (95% CI: 5.85 - 7.39). Conclusions: The incidence of chondrosarcoma in Iran is not as high as in other countries, but as patients are younger in Iran, the survival rate is worse compared to other countries. Therefore, better case findings and better care are needed to improve the patients' outcomes in Iran.
基于伊朗国家癌症登记处的伊朗软骨肉瘤流行病学研究
背景:软骨肉瘤被认为是继骨肉瘤之后第二常见的原发性骨恶性肿瘤。目的:根据伊朗国家癌症登记处(INCR),本研究旨在确定伊朗人群中软骨肉瘤的流行病学、发病率和生存率。方法:采用流行病学研究方法,对2008 - 2015年肢体软骨肉瘤患者的INCR数据进行评估。数据包括患者的人口统计学特征、诊断日期、肿瘤位置、患者生存期和肿瘤类型(基于国际肿瘤疾病分类(ICD-O-3;第1版,第3版)收集和分析。结果:732例入组患者中,男性425例(58.06%),女性307例(41.94%),平均年龄分别为44.08 (SD = 19.31)和45.06 (SD = 18.72)。男性和女性的年龄标准化发病率(ASIR)分别为1.73和1.27 / 100万人年。常规软骨肉瘤是最常见的亚型,ASIR为1.28,占软骨肉瘤患者的84.7%。约71.03%的软骨肉瘤患者(男性70.35%,女性71.99%)年龄在20 - 59岁之间。患者1年、3年、5年、7年生存率分别为0.87、0.73、0.57、0.47。平均生存时间为6.12年(95% CI: 5.85 - 7.39)。结论:伊朗软骨肉瘤的发病率不像其他国家那么高,但由于伊朗患者年龄较轻,生存率较其他国家差。因此,需要更好的病例发现和更好的护理来改善伊朗患者的预后。

期刊介绍: International Journal of Cancer Management (IJCM) publishes peer-reviewed original studies and reviews on cancer etiology, epidemiology and risk factors, novel approach to cancer management including prevention, diagnosis, surgery, radiotherapy, medical oncology, and issues regarding cancer survivorship and palliative care. The scope spans the spectrum of cancer research from the laboratory to the clinic, with special emphasis on translational cancer research that bridge the laboratory and clinic. We also consider original case reports that expand clinical cancer knowledge and convey important best practice messages.
