Abstract: Evaluating patient prognosis is prominent for predicting the effects and consequences of diseases. Systems can find interesting properties within a data set and predict unseen cases. Feature extraction and feature selection are the critical steps. In this work, a novel network-based feature extraction method is presented and tested on two cancer cases, namely (1) lung and bronchus cancer and (2) pancreatic cancer. Named as Signed Maximal Frequent Itemset Network, the proposed method uses maximal frequent itemsets as actors in a network and extracts features by considering their co-occurrence and structure of the sub-graph. To investigate patterns on prediction, the top ten maximal itemsets are selected with the recursive feature elimination method and their distributions are analysed. In conclusion, survival months are low when the information on the disease was unknown or blank, and higher in case chemotherapy was given and the primary site was labelled, such as head of the pancreas.
