Lower content of cerebrospinal fluid chemokines in patients with cancer cachexia.
Article in Acta cirurgica brasileira, 2026. 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
purposeCancer-associated cachexia (CC) is characterized by involuntary weight loss and poor prognosis. Central nervous system (CNS) inflammation has been linked to CC symptoms. This study evaluated inflammatory mediators in the cerebrospinal fluid (CSF) of patients with CC.
methodsVolunteers were recruited in Santarém, PA, Brazil, and divided into three groups: patients undergoing herniorrhaphy or cholecystectomy (n = 43)-control; cancer without cachexia (CWC, n = 13); and CC (n = 49). Blood and CSF were collected before anesthetic injection.
resultsCSF vascular endothelial growth factor (VEGF) and monocyte chemoattractant protein-1 (MCP-1) levels were reduced in CC (p < 0.0001; p 0.00017) and CWC (p = 0.0269; p = 0.0421) compared to control. CSF IP-10 was lower in CC (p = 0.0048). In CWC, CSF MCP-1 correlated with serum C reactive protein (rs = 0.78, p = 0.0098), leukocytes (rs = 0.72, p = 0.0235), lymphocytes (rs = -0.67, p = 0.0390) and monocytes (rs = -0.82, p = 0.0058). In CC, CSF interleukin (IL)-8 correlated with leukocytes (rs = 0.48, p = 0.0032) and MCP-1 with neutrophils (rs = 0.36, p = 0.0265) and eosinophils (rs = -0.37, p = 0.0218). CC patients showed lower quality of life than CWC (functional scale p = 0.0087; symptoms scale p = 0.0386).
conclusionCancer was related to changes in CSF cytokine levels, indicating that both tumor presence and cachexia modulate central inflammatory signaling. Correlations between CSF chemokines and blood immune cells suggest systemic interaction between peripheral immunity and the CNS.
