Serum Cytokeratin 18 as a Potential Early Marker for Chemotherapy Response in Breast Cancer Patients: A Prospective Study.
Article in Asian Pacific journal of cancer prevention : APJCP, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundCurrently, it is well recognized that response to neoadjuvant chemotherapy is an important predictive factor for survival in breast cancer patients. However, it is still an area of research about which patient would respond to the neoadjuvant chemotherapy.
methodsSerum CK18 levels were measured using ELISA from 52 newly diagnosed breast cancer patients, at presentation and after first cycle of neo-adjuvant chemotherapy. Pre- and post-treatment CK-18 levels were correlated with several clinical and pathological parameters. At the end of neoadjuvant treatment, changes in serum CK18 levels were correlated with tumors' response to therapy.
resultsSignificant elevation of pre-chemotherapy CK18 level was observed in patients who had progressive disease compared to those who had complete or partial response to therapy (P=0.006 and P<0.001, respectively). Significantly higher CK18 levels were observed post-chemotherapy in complete and partial responders, in contrast to patients with stable or progressive disease (P=0.012% and P=0.001%, respectively). The percent of change was significantly higher in complete responders compared to patients who had stable or progressive disease (P=0.043% and P=0.045%, respectively).
conclusionOur results suggest that patients with increasing CK18 level following chemotherapy are potential responders to their neoadjuvant protocol. Thus, the measurement of serum CK18 early in the treatment course could be a simple, noninvasive way to predict tumor response to neoadjuvant chemotherapy.
