Influence of biologic sex and obesity on liver recurrence and survival in patients undergoing upfront surgery for pancreatic adenocarcinoma.
Article in 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
backgroundThe influence of obesity and sex on outcomes in pancreatic adenocarcinoma (PDAC) remains unclear. The association between obesity (body mass index [BMI], ≥30) and biologic sex (male or female) for outcomes in patients with PDAC undergoing a surgery-first approach was investigated.
methodsA prospectively maintained pancreatic cancer database at the Memorial Sloan Kettering Cancer Center was queried to identify all patients undergoing surgery with a pathologic diagnosis of PDAC. Clinicodemographic variables, outcomes, and tumor mutational analyses for all available patients were collected. Cumulative incidence of first recurrence involving the liver was estimated via a cumulative incidence function. Multivariable Cox regression was used to investigate the association between BMI and sex for overall survival.
resultsFrom 2012 to 2022, 939 patients were identified who underwent surgery with a final pathologic diagnosis of PDAC. Median age was 70 years, 52% were male, and 24% were obese (BMI, ≥30). When dichotomized by sex and obesity status (BMI, <30 or ≥30), females with obesity had the lowest cumulative incidence of liver recurrence at 12 and 24 months postsurgery compared to all other groups (13% [95% CI, 7.2%-20%] and 15% [8.7%-23%], respectively). Females with obesity had the longest median overall survival at 37 months.
conclusionsAfter curative surgery for pancreatic cancer, females with obesity have a significantly lower rate of liver recurrence and the longest median overall survival. This does not appear to be related to surgical quality, receipt of adjuvant therapy, or tumor mutational profile. Investigation into host immune, metabolic, and hormonal parameters is paramount to understanding these differences.
