Pancreatic Acinar Cell Carcinoma: Demographics, Treatment, and Survival Outcomes, A Retrospective Population-Based Study.
Article in Journal of gastrointestinal cancer, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
purposePancreatic acinar cell carcinoma accounts for 1-2% of pancreatic tumors, with increasing frequency in recent years, and still represents a poor prognosis. This study aims to expand and update existing literature by analyzing national data gathered over almost two decades.
methodsData from 488 patients diagnosed with PACC in the Surveillance, Epidemiology, and End Results database were analyzed. This study employed the Cox regression method to compute hazard ratios and identify independent factors influencing survival. Additionally, Kaplan-Meier survival curves were utilized alongside the log-rank test.
resultsThe median age was 64.7 years with male predilection (70.5%). "Poorly differentiated carcinoma" was the most common subtype (45.8%). The liver was the most common site of metastases (31.3%). The 5-year observed overall survival (OS) rate was 19.2% (95% CI, 14.9-23.8). The 5-year cause-specific survival (CSS) rate was 22.4% (95% CI, 17.7-27.5). Male gender has a 5-year OS of 19.2% (95% CI, 14.0-25.1) compared to female OS of 30.2% (95% CI, 20.7-40.1). Patients treated with multimodal therapy (surgery with chemoradiation) over only surgery or chemotherapy had better 5-year OS, 53.5% (95% CI, 31.8-71.0). Age > 60 and distant stage were independent factors associated with increased mortality.
conclusionPancreatic acinar cell carcinoma is a rare, aggressive form of pancreatic cancer that primarily affects older adults. Our findings offer valuable insights to guide future clinical guidelines and tailored treatment strategies.
