Oncolysis using herpes simplex virus type 1 engineered to express cytosine deaminase and a fusogenic glycoprotein for head and neck squamous cell carcinoma.
Article in Archives of otolaryngology--head & neck surgery, 2010. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
objectiveTo determine if prodrug conversion of fluorocytosine to fluorouracil by an engineered herpes virus, OncoVEX(GALV/CD), enhances oncolytic therapy of head and neck squamous cell carcinoma.
designWe assessed the ability of OncoVEX(GALV/CD) and OncoVEX(GFP) to infect, replicate within, and lyse 4 head and neck squamous cell carcinoma lines in vitro. The effects of adding fluorocytosine with OncoVEX(GALV/CD) were evaluated.
resultsHead and neck squamous cell carcinoma was permissive to green fluorescent protein expression in100% of cells by OncoVEX(GFP) at a multiplicity of infection of 1 after 48 hours and supported logarithmic viral replication. Virus caused more than 60% cell death 6 days after exposure to virus at a multiplicity of infection of 0.1 in 3 of the 4 cell lines. Fluorocytosine did not enhance cytotoxicity induced by OncoVEX(GALV/CD) at a multiplicity of infection of 0.1. However, for the least-sensitive SCC25 cell line, virus at a multiplicity of infection of 0.01 was cytotoxic to only 4% of cells after 6 days but was cytotoxic to 35% of cells with fluorocytosine.
conclusionsOncoVEX(GALV/CD) efficiently infects, replicates within, and lyses head and neck squamous cell carcinoma at relatively low viral doses. Prodrug conversion by cytosine deaminase did not enhance therapy at viral doses that cause efficient cytotoxicity but may have beneficial effects in less-sensitive cell lines at low viral doses.
