The Presence of Portal Vein Thrombosis Alters the Classic Enhancement Associated with Diagnosis of Hepatocellular Carcinoma.

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
aimsTo determine whether the presence of portal vein thrombosis (PVT) where venous flow within the liver may be altered may delay the diagnosis of HCC and be associated with more advanced disease. We characterized the incidence and imaging characteristics of patients diagnosed with hepatocellular carcinoma in a cohort of patients with PVT compared with those without PVT.
methodsThis is a single-center retrospective study of a subset of HCC patients who underwent dynamic imaging for HCC screening and were found to have PVT. Data abstracted included demographic data, TNM stage, number/type of scans, AFP level, MELD score, and time to diagnosis.
resultsEighty-two patients newly diagnosed with HCC on screening were reviewed, of which 37 % (30/82) were found to have portal vein thrombosis. Patients with PVT had higher rates of atypical imaging associated with HCC compared with those without PVT (83 vs 56 %, p = 0.01) and had lower rates of portal venous washout (23 % vs 50 %, p = 0.018). Patients with PVT and HCC were also diagnosed at later TNM stage than those without PVT (70 vs 23 %, p < 0.001) and were significantly less likely to receive orthotopic liver transplant (3.6 vs 42 %, p < 0.001). Fourteen patients had preexisting PV clot without HCC; 16 developed PVT during screening or at diagnosis. Those with preexisting PVT were older (63. vs 55 years) and had higher rates of diagnosis of HCC using MRI (79 vs 21 % with CT, p = 0.01), compared with those without preexisting PVT.
conclusionThe presence of PVT found on dynamic imaging was associated with advanced stage of HCC at the time of diagnosis. Clinicians should have a high suspicion for HCC diagnosis in new liver lesions with atypical enhancement in the setting of PVT. In this setting, MRI was more frequently associated with HCC diagnosis.
