Cancer history and second cancer risk in polycythemia vera and essential thrombocythemia.
Article in Blood cancer journal, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Patients with myeloproliferative neoplasms (MPN), including polycythemia vera (PV) and essential thrombocythemia (ET), have an increased risk of second cancers (SC), although determinants of risk remain incompletely defined. We retrospectively analyzed 1968 consecutive patients with PV or ET (median follow-up 11.2 years) to identify predictors of SC. Cumulative incidence functions were estimated using competing-risk methodology, and predictors were assessed using Fine-Gray regression. During follow-up, SC occurred in 404 patients (20%), with non-melanoma skin cancer (NMSC) representing the most frequent subtype. In multivariable models including all cancer types, prior cancer (sHR 2.02, p < 0.001), older age (per 10 years: sHR 1.20, p < 0.001), male sex (sHR 1.39, p = 0.002), and hyperlipidemia (sHR 1.41, p = 0.003) independently predicted SC. After excluding NMSC, prior cancer remained associated with SC risk (sHR 1.48, p = 0.048). Notably, prior NMSC strongly predicted subsequent NMSC (sHR 6.48, p < 0.001), followed by prior non-NMSC cancer (sHR 2.11, p < 0.001), age (sHR 1.29, p < 0.001), and male sex (sHR 1.43, p = 0.018). TET2 mutations showed a borderline association with NMSC risk (sHR 1.73, p = 0.055), while hydroxyurea was not associated with SC, with a non-significant trend toward increased NMSC risk (sHR 1.82, p = 0.110). These findings support risk-adapted cancer surveillance in PV and ET, with particular emphasis on regular dermatologic monitoring.
