Leukocyte kinetics during the first cycle of chemotherapy predicts the outcome of patients with metastatic colorectal cancer and previous resection of the primary tumor.

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
backgroundMany reports suggest more activity of cytotoxic chemotherapy among patients with metastatic colorectal cancer (mCRC) who experience neutropenia, but it is not clear whether this finding is related to drug effect alone. The aim of the study is to identify the characteristics of patients whose peripheral blood cell kinetics (PBCK) is related to the outcome.
methodsThe study is a retrospective analysis of patients with mCRC who had received first-line chemotherapy at Sanremo hospital from 2010 to 2015, evaluating seventeen baseline variables, six related to systemic inflammatory response activation (SIRA), and six to peripheral blood cell kinetics after one cycle. The relationship of peripheral blood cell kinetics variables was evaluated by tumor location, SIRA, and timing of metastases.
resultsAmong 203 eligible patients, only four variables were able to independently predict survival (age, CA 19-9, number of drugs, chemotherapy-induced leukopenia after the first cycle or CIL-1). After stratification by tumor location or by SIRA, no relationship of PBCK variables with prognosis was present. On the contrary, after stratification by timing of metastasis, the prognostic role of CIL-1 was evident among patients with metachronous metastases, particularly among those with low SIRA and colon tumors, whereas the leukocyte reduction after the first cycle (WR) predicted longer survival of patients with synchronous metastases and a previous resection of the primary tumor (PTR).
conclusionsAbsolute leukocyte reduction (CIL-1) predicts a better OS of patients with metachronous metastases, whereas relative leukocyte reduction (WR) could be prognostic among patients with synchronous metastases who have received PTR.
