The prognostic assessment system for lung cancer patients combining pathological images and clinical variables according to claim 6, characterized in that, The second analysis module includes: The processing submodule is used to determine the dimensional unit of each clinical variable, classify multiple clinical variables according to the dimensional unit, and perform one-hot coding standardization on each type of clinical variable. The fourth determination submodule is used to determine the network type of the clinical feature network and determine the analysis strategy based on the network type. The network types include: patient network and variable network. The fifth submodule is used to analyze the processed clinical variables according to the analysis strategy to determine the target patient's subgroup and disease type; The generation submodule is used to generate second analysis results based on the target patient's subgroup and disease type.

10. The lung cancer patient prognostic assessment system combining pathological images and clinical variables according to claim 6, characterized in that, The prediction module includes: The sixth determination submodule is used to determine the target stage of tumor development in the target patient based on the results of the first analysis, and to obtain the target lymphocyte variable at the target stage of tumor development. The seventh determination submodule is used to determine the target type of lung cancer in the target patient based on the results of the second analysis, and to determine the deterioration status parameters of the target type of lung cancer; The prediction submodule is used to predict the survival time of target patients based on lymphocyte target variables at the target stage of tumor development and the deterioration status parameters of the target type of lung cancer using a multilayer perceptual model. The eighth determination submodule is used to determine the survival months of the target patient based on the survival cycle time and the current time point.
