INTRODUCTION High hospital case volumes are associated with improved treatment outcomes for numerous diseases. We assessed the association between academic non-profit hospital case volume and survival of adult glioblastoma patients. METHODS From the nationwide Finnish Cancer Registry, we identified all adult (≥ 18 years) patients with histopathological diagnoses of glioblastoma from 2000 to 2013. Five university hospitals (treating all glioblastoma patients in Finland) were classified as high-volume (one hospital), middle-volume (one hospital), and low-volume (three hospitals) based on their annual numbers of cases. We estimated one-year survival rates, estimated median overall survival times, and compared relative excess risk (RER) of death between high, middle, and low-volume hospitals. RESULTS A total of 2,045 patients were included. The mean numbers of annually treated patients were 54, 40, and 17 in the high, middle, and low-volume hospitals, respectively. One-year survival rates and median survival times were higher and longer in the high-volume (39%, 9.3 months) and medium-volume (38%, 8.9 months) hospitals than in the low-volume (32%, 7.8 months) hospitals. RER of death was higher in the low-volume hospitals than in the high-volume hospital (RER = 1.19, 95% CI 1.07-1.32, p = 0.002). There was no difference in RER of death between the high-volume and medium-volume hospitals (p = 0.690). CONCLUSION Higher glioblastoma case volumes were associated with improved survival. Future studies should assess whether this association is due to differences in patient-specific factors or treatment quality.

胶质母细胞瘤生存率的差异:一项全国性的观察性研究。

引言大量的医院病例与多种疾病的治疗效果改善有关。我们评估了学术性非营利性医院病例数与成年胶质母细胞瘤患者生存率之间的关联。方法从2000年至2013年,我们从全国性的芬兰癌症登记处确定了所有成年(≥18岁)患有胶质母细胞瘤组织病理学诊断的患者。五所大学医院(对芬兰的所有胶质母细胞瘤患者进行了治疗)被列为高容量(一家医院)中型(一家医院)和小批量(三家医院),基于其每年的病例数。我们估算了高,中,低容量医院之间的一年生存率,中值总体生存时间,并比较了死亡的相对超风险(RER)。结果共纳入2,045例患者。在高,中,低容量医院中,每年接受治疗的患者的平均数分别为54、40和17。高容量医院(39%,9.3个月)和中容量医院(38%,8.9个月)的一年生存率和中位生存时间比低容量医院(32%,7.8个月)更高且更长医院。小批量医院的死亡RER高于大批量医院(RER = 1.19,95%CI 1.07-1.32,p = 0.002)。大中型医院之间的死亡RER没有差异(p = 0.690)。结论胶质母细胞瘤病例增多与生存率提高有关。未来的研究应评估这种关联是否是由于患者特定因素或治疗质量的差异所致。和小型医院。高容量医院(39%,9.3个月)和中容量医院(38%,8.9个月)的一年生存率和中位生存时间比低容量医院(32%,7.8个月)更高且更长医院。小批量医院的死亡RER高于大批量医院(RER = 1.19,95%CI 1.07-1.32,p = 0.002)。大中型医院之间的死亡RER没有差异(p = 0.690)。结论胶质母细胞瘤病例增多与生存率提高有关。未来的研究应评估这种关联是否是由于患者特定因素或治疗质量的差异所致。和小批量医院。高容量医院(39%,9.3个月)和中容量医院(38%,8.9个月)的一年生存率和中位生存时间比低容量医院(32%,7.8个月)更高且更长医院。小批量医院的死亡RER高于大批量医院(RER = 1.19,95%CI 1.07-1.32,p = 0.002)。大中型医院之间的死亡RER没有差异(p = 0.690)。结论胶质母细胞瘤病例增多与生存率提高有关。未来的研究应评估这种关联是否是由于患者特定因素或治疗质量的差异所致。3个月)和中型医院(38%,8.9个月)要比小容量(32%,7.8个月)医院高。小批量医院的死亡RER高于大批量医院(RER = 1.19,95%CI 1.07-1.32,p = 0.002)。大中型医院之间的死亡RER没有差异(p = 0.690)。结论胶质母细胞瘤病例增多与生存率提高有关。未来的研究应评估这种关联是否是由于患者特定因素或治疗质量的差异所致。3个月)和中型医院(38%,8.9个月)要比小容量(32%,7.8个月)医院高。小批量医院的死亡RER高于大批量医院(RER = 1.19,95%CI 1.07-1.32,p = 0.002)。大型医院和中型医院之间的死亡RER没有差异(p = 0.690)。结论胶质母细胞瘤病例增多与生存率提高有关。未来的研究应评估这种关联是否是由于患者特定因素或治疗质量的差异所致。结论胶质母细胞瘤病例增多与生存率提高有关。未来的研究应评估这种关联是否是由于患者特定因素或治疗质量的差异所致。结论胶质母细胞瘤病例增多与生存率提高有关。未来的研究应评估这种关联是否是由于患者特定因素或治疗质量的差异所致。
