1 · What the graph read from it

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.

2 · The registry

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

introductionThe objective of this study was to examine the prognostic value of Ki-67 expression in conversion therapy for colorectal liver-confined metastases.

methodsWe enrolled a total of 96 patients including 54 patients who received oxaliplatin- or irinotecan-based chemotherapy and curative hepatectomy for initially unresectable metastases (conversion group) and 42 patients with initially resectable liver metastases (straight hepatectomy group). Ki-67 expression was examined in 96 resected specimens but excluded the 2 specimens that revealed no residual cancer cells in conversion group.

resultsConversion therapy leads to greater survival that is equivalent to that straight hepatectomy group. In conversion group, high Ki-67 expression (> 30%) levels were detectable in 33 patients (64%) after chemotherapy prior to conversion therapy. High Ki-67 expression was significantly associated with shorter disease-free survival and worse overall survival (P < 0.01 in both), and was an independent worse prognostic factor of disease-free survival and overall survival (hazard ratio [HR] and P-values were 5.608, 0.001 and 5.366, 0.04, respectively) in patients with conversion therapy. Interestingly, even in the patients with RECIST PR (n = 32), high Ki-67 expression was significantly shorter disease-free survival compared to low Ki-67 expression (P < 0.001). In contrast to conversion group, there was no significant difference in disease free survival and overall survival between low (n = 14, 33%) and high (n = 28, 67%) Ki-67 expressions in patients with straight hepatectomy (P = 0.14 and 0.74, respectively).

conclusionsResidual Ki-67 expression is a useful biomarker for worse prognostic outcomes after conversion therapy. High Ki-67 expression may be a biomarker of micrometastases containing aggressive cancer cells.
