1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

Abstract

purposeTargeting of integrin α(ν)β(3) with molecular imaging agents offers great potential in early detection and monitoring of tumour angiogenesis. Recently, an RGD (Arg-Gly-Asp) tracer, (99m)Tc-3P(4)-RGD(2), with high affinity to integrin α(ν)β(3) and in vivo tumour uptake was developed. In this study, we evaluate the feasibility of this novel radiotracer in the noninvasive differentiation of solitary pulmonary nodules (SPNs).

methodsTwenty-one patients with SPNs on CT were studied scintigraphically after administration of (99m)Tc-3P(4)-RGD(2) with a dose of 939 ±  118 MBq. Image interpretation using a 5-point scale was performed by one thoracic radiologist for CT and three nuclear medicine radiologists for single photon emission computed tomography (SPECT). Scintigraphic images were also analysed semiquantitatively by calculating tumour to normal tissue ratio (T/N). The "gold standard" was based on the histopathological diagnosis of the surgical samples from all recruited patients. A fraction of the samples were analysed immunohistochemically for integrin α(v)β(3) expression.

resultsAmong the 21 SPNs, 15 (71%) were diagnosed as malignant and 6 (29%) were benign. The mean size for SPNs was 2.2 ±  0.6 cm. The sensitivity and specificity for CT interpretation, SPECT visual and semiquantitative analysis were 80/67%, 100/67% and 100/67%, respectively. All SPNs classified as indeterminate by CT were correctly diagnosed by (99m)Tc-3P(4)-RGD(2) scintigraphy. The empirical receiver-operating characteristic (ROC) areas were 0.811 [95% confidence interval (CI) 58-95%] for CT, 0.833 (95% CI 61-96%) for SPECT and 0.844 (95% CI 62-96%) for T/N ratios, respectively. Immunohistochemistry confirmed α(ν)β(3) expression in malignant and benign nodules with uptake in (99m)Tc-3P(4)-RGD(2) scintigraphy.

conclusionIn this first-in-human study, we demonstrated the feasibility of using (99m)Tc-3P(4)-RGD(2) scintigraphy in differentiating SPNs. This procedure appears to be highly sensitive in detection of malignant SPNs. SPECT visual analysis seems to be sufficient for characterization of SPNs.
