Serous cystadenocarcinoma of the pancreas: a population-based study.
Article in World journal of surgical oncology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundSerous cystadenocarcinoma (SCAc) of the pancreas is an exceptionally rare malignant pancreatic neoplasm, and its clinical characteristics, treatment patterns, and prognosis remain poorly defined. The aim of this population-based study was to characterize the demographic and clinical features, treatment patterns, and survival of patients with pancreatic SCAc.
methodsPatients with microscopically confirmed SCAc were identified from the Surveillance, Epidemiology, and End Results (SEER) registry. Demographic, tumor-related, treatment, and survival data were analyzed using descriptive statistics and Kaplan-Meier survival analysis.
resultsTwenty-one patients with SCAc were identified. Median age at diagnosis was 69 years, and 13 patients (62%) were female. Tumors most frequently involved the pancreatic body or tail. Disease was localized in 4 patients (19%), regional in 6 (29%), distant in 9 (43%), and unstaged in 2 (10%). Surgical resection was performed in 12 patients (57%), and 6 (29%) received chemotherapy. Estimated 5-year overall survival (OS) was 60.5% for the overall cohort. Five-year OS was 73.3% among patients who underwent resection and 44.4% among those who did not.
conclusionsPancreatic SCAc is a rare malignancy with frequent involvement of the pancreatic body or tail. Surgical resection was the most common treatment, whereas chemotherapy was used in a minority of patients. Population-based data suggest relatively favorable long-term survival.
