title: The Minimum Basic Data Set (MBDS) as a tool for cancer epidemiological surveillance.
abstract: OBJECTIVE
  This work aims to evaluate the Minimum Basic Data Set (MBDS) as a data source in the detection of malignant tumors and explore its usefulness as a tool for epidemiological surveillance of cancer.
  
  
  METHODS
  MBDS hospital data discharge from Prince of Asturias University Hospital (HUPA, Alcalá de Henares, Madrid, Spain) and cancer cases recorded in the Hospital Cancer Registry (HCR) have been collected for the period between January 2012 and June 2014. Both databases have been linked by the number of clinical history. For the process of evaluation of MBDS, the types of cancer with more than 100 cases have been analyzed and sensitivity, specificity, positive and negative predictive values(PPV, NPV) of MBDS were calculated using as reference the diagnoses recorded in the HCR.
  
  
  RESULTS
  3438 cases of cancer were accounted in the MBDS and 2445 in the HCR. The MBDS has a sensitivity to detect cases of cancer above 60%, although it varies depending on the type of tumor, reaching the highest values for bladder cancer. The specificity and the VPN were very high for all types of cancer studied, always on top of 95%. Finally, the VPP is generally moderate, between 50% and 70%.
  
  
  CONCLUSIONS
  The systematic exploitation of the MBDS can provide a valuable tool in the monitoring of cancer by its acceptable sensitivity and high specificity, allowing obtaining information without the delays involved in the consolidation of the annotations of the HCR. Furthermore, its use could partly mitigate the lack of data in important regions of Spain.
