Abstract
Background
Osteosarcoma is considered a highly vascularized bone tumor with early metastatic dissemination through intratumoral blood vessels mostly into the lung. Novel targets for therapy such as tumor vascularization are highly warranted since little progress has been achieved in the last 30 years. However, proof of relevance for vascularization as a major prognostic parameter has been hampered by tumor heterogeneity, difficulty in detecting microvessels by immunohistochemistry, and small study cohorts. Most recently, we demonstrated that highly standardized whole-slide imaging could overcome these limitations (Kunz et al., PloS One 9(3):e90727, 2014). In this study, we applied this method to a multicenter cohort of 131 osteosarcoma patients to test osteosarcoma vascularization as a prognostic determinant.
Methods
Computer-assisted whole-slide analysis, together with enzymatic epitope retrieval, was used for CD31-based microvessel quantification in 131 pretreatment formalin-fixed and paraffin-embedded biopsies from three bone tumor centers. Kaplan–Meier-estimated survival and chemoresponse were determined and multivariate analysis was performed. Conventional hot-spot-based microvessel density (MVD) determination was compared with whole-slide imaging.
Results
We detected high estimated overall (p ≤ 0.008) and relapse-free (p ≤ 0.004) survival in 25 % of osteosarcoma patients with low osteosarcoma vascularization in contrast to other patient groups. Furthermore, all patients with low osteosarcoma vascularization showed a good response to neoadjuvant chemotherapy. Comparison of conventional MVD determination with whole-slide imaging suggests false high quantification or even exclusion of samples with low osteosarcoma vascularization due to difficult CD31 detection in previous studies.
Conclusion
Low intratumoral vascularization at the time of diagnosis is a strong predictor for prolonged survival and good response to neoadjuvant chemotherapy in osteosarcoma.

Effects of quantification methods on vessel quantification results in representative osteosarcoma samples with varying vascularization. Representative whole- slide scans of osteosarcoma samples with heterogeneous (a) and homogeneous (b) distribution of intra- tumor vessels after CD31-immunostaining. CD31-immunoreactive cells show red cell surface staining. Sections were counterstained by hematoxylin. Inserts show a 3.7-fold (a), respectivel 3.1-fold (b) magnification of a vascular hot spot (green circle). Vessel quantification result obtained by MVD within hot spots or CD31-immunoreactive area within the whole section are indicated. Note the varying micro vessel morphology and size, effecting MVD counts. Supplementary material 1 (TIFF 14,814 kb)
