[18F]fluoromethylcholine as a chemotherapy response read-out in prostate cancer cells.
Article in Molecular imaging and biology, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeThe objective of the present study is to determine whether uptake of [(18)F]fluoromethylcholine ([(18)F]FCH) in comparison with 2-deoxy-2-[(18)F]fluoro-D-glucose ([(18)F]FDG) accurately reflects chemotherapy efficacy at the tumor cell level in prostate cancer (PC). PROCEDURES: The effects of docetaxel and cabazitaxel on viable tumor cell number were explored in four PC cell lines. Cellular uptake of [(18)F]FDG and [(18)F]FCH was compared with the effects measured using sulforhodamine B (SRB) assay, cell counting and colony formation assay (CFA), as proximators of viable tumor cell number. Agreement between uptake and cell numbers was assessed by Bland-Altman plots.
results[(18)F]FCH uptake in all PC cell lines significantly correlated to the cell numbers surviving the respective drug concentrations. Bland-Altman analysis showed that [(18)F]FDG uptake resulted in signal overestimation and higher variability after chemotherapy.
conclusions[(18)F]FCH uptake correlates well with viable tumor cell numbers remaining after docetaxel and cabazitaxel exposure. Radiolabeled choline is a potential response monitoring biomarker after chemotherapy for PC.
