Positron emission tomography (PET): expanding the horizons of oncology drug development.
Review in Investigational new drugs, 2003. 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
Positron emission tomography (PET) allows three-dimensional quantitative determination of the distribution of radioactivity permitting measurement of physiological, biochemical, and pharmacological functions at the molecular level. Until recently, no method existed to directly and noninvasively assess transport and metabolism of neoplastic agents as a function of time in various organs as well as in the tumor. Standard preclinical evaluation of potential anticancer agents entails radiolabeling the agent, usually with tritium or 14C, sacrifice experiments, and high-performance liquid chromatography (HPLC) analysis to determine the biodistribution and metabolism in animals. Radiolabeling agents with positron-emitting radionuclides allows the same information to be obtained as well as in vivo pharmacokinetic (PK) data by animal tissue and plasma sampling in combination with PET scanning. In phase I/II human studies, classic PK measurements can be coupled with imaging measurements to define an optimal dosing schedule and help formulate the design of phase III studies that are essential for drug licensure [1]. Many of the novel agents currently in development are cytostatic rather than cytotoxic and therefore, the traditional standard endpoints in phase I and II studies may no longer be relevant. The use of a specialized imaging modality that allows PK and pharmacodynamic (PD) evaluation of a drug of interest has been proposed to permit rapid and sensitive assessment of the biological effects of novel anticancer agents. The progress to date and the challenges of incorporating PET technology into oncology drug development from the preclinical to clinical setting are reviewed in this article.
