The survival of lung cancer patients in the UK is lower than in other similar European countries. The reasons for this are unclear.
Two areas were selected with a similar incidence of lung cancer: Teesside in Northern England and Varese in Northern Italy. Data were collected prospectively on all new cases of lung cancer diagnosed in the year 2000. Comparisons were made of basic demographic characteristics, management, and survival.
There were 268 cases of lung cancer in Teesside and 243 in Varese. Patients in Teesside were older (p<0.05), were more likely to have smoked (p<0.001), had a higher occupational risk (p<0.001), higher co-morbidity (p<0.05), and poorer performance status (p<0.001). Fewer patients in Teesside presented as an incidental finding (p<0.001) and the histological confirmation rate was lower than in Varese (p<0.01). In Teesside there were more large cell carcinomas (p<0.001), more small cell carcinomas (p<0.05), and fewer early stage non-small cell lung cancers (p<0.05). The resection rate was lower in Teesside (7% v 24%; p<0.01) and more patients received no specific anti-cancer treatment (50% v 25%; p<0.001). Overall 3 year survival was lower in Teesside (7% v 14%; p<0.001). Surgical resection was the strongest multivariate survival predictor in Varese (HR = 0.46) and Teesside (HR = 0.31). Co-morbidity in Teesside resulted in a significantly lower resection rate (p<0.001).
Patients with lung cancer in Teesside presented at a later stage, with more aggressive types of tumour, and had higher co-morbidity than patients in Varese. As a result, the resection rate was significantly lower and survival was worse.
英国肺癌患者的生存率低于其他类似的欧洲国家。其原因尚不清楚。
选择肺癌发病率相似的两个地区:英格兰北部的蒂斯河畔斯托克和意大利北部的瓦雷泽。前瞻性收集2000年诊断出的所有肺癌新病例的数据。对基本人口统计学特征、治疗和生存率进行比较。
蒂斯河畔斯托克有268例肺癌病例,瓦雷泽有243例。蒂斯河畔斯托克的患者年龄更大(p<0.05),更有可能吸烟(p<0.001),职业风险更高(p<0.001),合并症更多(p<0.05),身体状况更差(p<0.001)。蒂斯河畔斯托克偶然发现的患者较少(p<0.001),组织学确诊率低于瓦雷泽(p<0.01)。蒂斯河畔斯托克的大细胞癌更多(p<0.001),小细胞癌更多(p<0.05),早期非小细胞肺癌更少(p<0.05)。蒂斯河畔斯托克的切除率较低(7%对24%;p<0.01),更多患者未接受特定的抗癌治疗(50%对25%;p<0.001)。总体而言,蒂斯河畔斯托克的3年生存率较低(7%对14%;p<0.001)。手术切除是瓦雷泽(HR = 0.46)和蒂斯河畔斯托克(HR = 0.31)最强的多变量生存预测因素。蒂斯河畔斯托克的合并症导致切除率显著降低(p<0.001)。
与瓦雷泽的患者相比,蒂斯河畔斯托克的肺癌患者就诊时分期较晚,肿瘤类型更具侵袭性,合并症更多。因此,切除率显著较低,生存率更差。
