Hepatocellular carcinoma: tumor heterogeneity and recurrence after preoperative locoregional therapy.

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
How locoregional therapy (LRT) may change tumor compositional and functional heterogeneity, consequently contributing to treatment resistance and tumor recurrence remains largely unknown. A series of hepatocellular carcinomas (HCCs) treated with preoperative locoregional therapy (LRT) that relapsed after surgery was studied. Thirty HCCs comprising 15 patients treated with LRT prior to liver transplantation (n = 14)/surgical resection (n = 1) were studied. Five patients undergoing pre-transplant LRT, comprising 11 HCCs, presented tumor recurrence (median recurrence time = 10 months). Clinicopathological data and immunoexpression of proliferation markers (Ki67, p53), cholangiocytic/hepatic progenitor cell (HPC) markers (EpCAM)/BerEp4, CK19, CK7) and mesenchymal markers (ASMA, vimentin) were evaluated in tumoral epithelial/stromal cells and in peritumoral parenchyma. Higher grading of tumor differentiation, microvascular invasion and tumoral cell p53 expression significantly associated with recurrence (p < 0.05). Piecemeal necrosis features were more frequent in tumors that recurred (p < 0,05). Tumoral and peritumoral Ki67 expression and EpCAM, CK19 and CK7 expression in tumoral cells tended to be higher in treated tumors that recurred. Peritumoral expression of cholangiocytic/HPC markers and tumoral epithelial and stromal cellular expression of mesenchymal markers tended to be higher for tumors without recurrence. Recurrence after transplant with preoperative LRT might be associated with poor HCC differentiation, higher cellular proliferation rate, peritumoral piecemeal necrosis features and cholangiocytic/HPC phenotypes. Understanding HCC progression factors after LRT might be important for optimizing patient selection for treatment, improving surveillance after LRT and to explore synergies between LRT and systemic targeted therapies to prevent recurrence.
