Invasion category-oriented lymph node metastases of cholangiocarcinoma and the prognostic impact.
Article in Langenbeck's archives of surgery, 2020. 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
purposeIt was speculated that intrahepatic cholangiocarcinoma (ICC) invasion would influence cancer progression, such as lymph node (LN) metastasis, and the efficacy of LN dissection (LND). The purpose of this study is to evaluate the LN metastatic pattern of intrahepatic cholangiocarcinoma, including the invasion category and prognosis after surgical resection, in order to explore effective LND.
methodsWe analyzed a prospectively collected cohort for ICC with a previously reported invasion category: hilar type, showing invasion to the main or first branch of Glisson; peripheral type, showing no invasion to less than the third branch; and intermediate type, for all others.
resultsData from a total of 180 patients who underwent surgical resection were analyzed (LN dissection in 142 (79%)). In single ICC, hilar type had a higher LN metastatic rate than the others (hilar; 23/45 (51%), intermediate; 7/25 (28%), peripheral; 1/34 (3%)). Although the survival with LN metastasis (LN+) was worse, single and hilar/intermediate ICC LN+ had a better survival than peripheral type LN+ (3-year OS: hilar/intermediate 30-37%, peripheral 0%). The most frequent LN metastatic region was the hepatico-duodenal ligament for all invasion categories, and the LN metastatic region was not related to the survival. In peripheral ICC, LND did not affect the survival. By contrast, hilar/intermediate ICC LN+ had a better survival than did peripheral ICC LN+, and the 3-year OS was ≥ 20%.
conclusionLN metastasis depended on the ICC invasion category in addition to the tumor number, which affected patients' survival and the need for LND. In hilar-type disease, LN dissection may contribute to the survival.
