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.

2 · The registry

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

backgroundPrimary adenosquamous carcinoma of the prostate is an extremely rare and aggressive variant, accounting for less than 1% of all prostate cancers. Due to its rarity, the prognosis is poor, with no established treatment. Prostate-specific antigen levels are typically within the normal range in primary adenosquamous carcinoma of the prostate. CASE PRESENTATION: We present the case of a 57-year-old East Asian male in whom pathological and imaging findings led to the diagnosis of primary adenosquamous carcinoma of the prostate. His prostate-specific antigen levels were initially high and continued to increase rapidly thereafter to 161.89 ng/ml. Although hormonal therapy achieved a reduction in prostate-specific antigen levels, the disease progressed rapidly, with extensive metastases to multiple sites, including the lung, lymph nodes, pancreas, bone, and skeletal muscle as an extremely rare metastatic site. The patient died 6 months after diagnosis despite subsequent multidisciplinary treatment.

conclusionThis patient with primary adenosquamous carcinoma of the prostate demonstrated rapid increase of prostate-specific antigen as an uncommon clinical feature. Further accumulation of cases is needed to understand and treat this rare and aggressive disease.
