Impact of Lymphatic and Venous Invasion Patterns on Postoperative Prognosis and Distant Metastasis in Esophageal Squamous Cell Carcinoma After Preoperative Chemotherapy.

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
backgroundLymphovascular invasion (LVI) is reported to correlate with postoperative prognosis in esophageal squamous cell carcinoma (ESCC). However, reports analyzing lymphatic and venous invasion separately are rare, and no studies have examined the correlation in resected specimens after neoadjuvant chemotherapy (NAC). This study evaluated the postoperative prognosis and distant metastatic recurrence patterns in ESCC patients who underwent esophagectomy after NAC.
methodsThis retrospective study analyzed 427 ESCC patients who underwent radical esophagectomy after NAC. The study examined the association of LVI patterns with postoperative overall survival (OS), recurrence-free survival (RFS), and distant metastasis-free survival (DMFS). The study also evaluated the correlation with postoperative distant metastasis patterns.
resultsMultivariate analyses showed that patients with venous invasion (VI) alone had significantly worse OS (HR, 2.99; p < 0.001), RFS (HR, 2.92; p < 0.001), and DMFS (HR, 3.63; p < 0.001) than patients without LVI. Patients with both lymphatic invasion (LI) and VI had the worst OS (HR, 4.23; p < 0.001), RFS (HR, 3.38; p < 0.001), and DMFS (HR, 4.59; p < 0.001) among all groups. For the ypN0 patients, VI positivity was the only independent risk factor for DMFS (HR, 5.33; p < 0.001). Regarding distant organ metastasis, liver, brain, and bone metastasis were more frequently detected in patients with both LI and VI than in patients with other LVI patterns.
conclusionsThe study showed that ESCC patients treated with NAC who have resected specimens positive for VI, especially those also with positive lymphatic invasion, have a worse postoperative prognosis and a higher risk for postoperative distant metastases than those without LVI. More aggressive postoperative adjuvant therapy may be suitable for improving the prognosis of such patients.
