Cancer patients are at a higher risk of stroke. However, the evidence is unclear if high D-dimer in stroke patients can suggest the diagnosis of concomitant cancer or the development of stroke in a cancer patient. The objective is to assess the evidence available on the baseline D-dimer level in stroke patients with and without cancer.  \nMaterials and Methods: We conducted the systematic review and meta-analysis using the Preferred Reporting Items for Systematic Reviews and Metaanalysis guidelines. We searched PUBMED, Cochrane, ScienceDirect, and Scopus for potentially eligible articles published till June 2023. All the review steps were iterative and done independently by two reviewers. The Newcastle-Ottawa scale tool was used to assess the quality of included studies for case control and cohort studies and the Agency for Healthcare Research and Quality tool for cross-sectional studies. The qualitative synthesis is presented narratively, and quantitative synthesis is shown in the forest plot using the random effects model. I2 of more than 60% was considered as high heterogeneity.  \nResults: The searches from all the databases yielded 495 articles. After the study selection process, six papers were found eligible for inclusion in the qualitative and quantitative synthesis. In the present systematic review, 2651 patients with ischemic infarcts are included of which 404 (13.97%) patients had active cancer while 2247 (86.02%) did not. The studies included were of high quality and low risk of bias. There were significantly higher baseline D-dimer levels in stroke patients with cancer than in non-cancer patients with a mean difference of 4.84 (3.07–6.60) P \u003C 0.00001.  \nConclusion: D-dimer is a simple and relatively non-expensive biomarker that is increased to significant levels in stroke patients, who have cancer and therefore may be a tool to predict through screening for active or occult cancer in stroke patients.  \nKeywords: Cancer, D-dimer, Stroke, Prognosis, Cerebral infarction  \nINTRODUCTION  \nThe D-dimer is the fibrin degradation product at minimally detectable levels in normal individuals; however, it increases in stroke patients, thrombolytic/fibrinolytic disorders, and critically sick patients. [1-3] Patients with malignancy are especially prone to develop ischemic stroke by various mechanisms including hypercoagulable state and tumor occlusion. [3-8] Various studies have reported that high plasma D-dimer levels can be seen in cancer-associated ischemic stroke patients, further supporting the assumption that hypercoagulability is a significant risk factor for developing  \nstroke in cancer patients. [2,3,9-13] Studies have shown that abnormal D-dimer levels and multiple territories of infarctsare predictors of malignancy in a stroke patient.
