Validation of the Rat Model of Prostate Cancer: Correlating Seminal Vesicle Lesions With Dorsolateral Prostate Lesions.

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
BACKGROUND/
aimLesions in the seminal vesicle are described in the most used protocols for prostate cancer (PCa) induction. This study aimed to characterize the lesions of seminal vesicles associated with a protocol of PCa induction in rats to contribute to better characterization of this model. MATERIALS AND
methodsForty-five male Wistar Unilever rats were randomly divided into two control groups: CONT1 (n=10) and CONT2 (n=10); and two PCa-induced groups: IND1 (n=10) and IND2 (n=15), sacrificed at 35 and 61 weeks, respectively. Animals from the induced groups were exposed to a multistep protocol for PCa induction. Animals, seminal vesicles and dorsolateral prostate were weighed. Seminal vesicles and dorsolateral prostate were submitted to histopathological and immunohistochemical analysis.
resultsAnimals in which PCa was induced had a lower mean body weight when compared with the control animals (p<0.05). The relative mean seminal vesicle weight was higher in groups with PCa when compared with control groups (p<0.05). Although the differences were not statistically significant, animals from the IND2 group developed more lesions than animals from the IND1 and CONT2 groups. It is worth noting that the animals from group IND2 developed papillary adenomas and carcinomas in situ, which were not observed in any other group. Similar to observations in seminal vesicles, animals from group IND2 developed more dorsolateral prostate lesions than animals from the IND1 group (p<0.05).
conclusionWe observed that the longer the exposure to testosterone was, the greater was the incidence of preneoplastic and neoplastic lesions in both the seminal vesicle and the prostate, suggesting that testosterone exposure affects the spectrum of developed lesions.
