A system and method for lung cancer screening is provided. The system includes a database including structured patient information for a patient population and a domain knowledge base including information about lung cancer; an individual patient record; and a processor for analyzing the patient record with data from the database to determine if a patient has indications of lung cancer. The method includes the steps of inputting patient-specific data into a patient record; performing at least one lung cancer screening procedure on a patient, wherein at least one result from the at least one procedure is inputted into the patient record in a structured format; and analyzing the patient record with a domain knowledge base to determine if the patient has indications of lung cancer.

What is claimed is: 1. A method for screening for lung cancer, the method comprising the steps of: inputting patient-specific data into a patient record, the patient-specific data representing the patient; performing at least one lung cancer screening procedure on a patient, wherein at least one result from the at least one procedure is input into the patient record; mining data of the patient record based on a domain knowledge base specific to lung cancer, wherein the data of the patient record is stored in structured and unstructured formats, and wherein the mining comprises populating, with populated data, a structured database compiled for lung cancer from the structured and unstructured data; analyzing, with a processor, the populated data of the structured database with the domain knowledge base to determine whether the patient has indications of lung cancer; and presenting a report as a function of a result of the analyzing; further comprising the steps of: analyzing the structured database of structured patient information for a patient population to create a model of a similar patient with similar characteristics of the patient based on the patient record; and determining a progression of lung cancer in the patient based on the model, wherein the structured database of population-based structured patient information is compiled by mining data of population-based patients based on the domain knowledge base, wherein the data is stored in structured and unstructured formats. 2. The method as in claim 1, further comprising the step of diagnosing a current state of the patient. 3. The method as in claim 1, further comprising the step of determining a screening protocol for the patient based on the model. 4. The method as in claim 3, wherein the screening protocol includes a time for a next procedure for the individual patient based on the model. 5. The method as in claim 4, wherein the next testing procedure is a computerized tomography (CT) scan. 6. The method as in claim 4, further comprising the step of balancing costs of potential tests to be performed against a risk of late detection of lung cancer to determine a maximum allowable time between tests for the individual patient. 7. The method as in claim 3, further comprising the steps of determining a testing procedure to be next performed for the individual patient and determining a time for the testing procedure for the individual patient. 8. The method as in claim 1, wherein the performing step includes conducting an imaging study of the patient; and detecting nodules present in the imaging study. 9. The method as in claim 8, wherein the analyzing step includes registering the imaging study with previous imaging studies; and determining growth of the detected nodules over the imaging studies. 10. The method as in claim 8, wherein the imaging study is a computerized tomography (CT) scan. 11. The method as in claim 1 wherein the patient-specific data in the patient record includes information other than derived from an image, and wherein the analyzing comprises analyzing at least the information other than derived from an image with the domain knowledge base. 12. The method as in claim 1 wherein analyzing comprises making a probabilistic inference from information in the patient record as a function of the domain knowledge base. 13. The method of claim 1 wherein mining comprises combining evidence and inferring from the combination. 14. The method of claim 1 wherein analyzing the structured database comprises resolving conflicts based on the domain knowledge base. 15. A method for screening for lung cancer, the method comprising the steps of: inputting patient-specific data into a patient record, the patient-specific data representing the patient; performing at least one lung cancer screening procedure on a patient, wherein at least one result from the at least one procedure is input into the patient record; analyzing, with a processor, the patient record with a domain knowledge base to determine whether the patient has indications of lung cancer; wherein the inputting of patient-specific data into the patient record is performed by mining historical data of the patient, the historical data being in structured and unstructured formats, the mining based on the domain knowledge base specific to lung cancer, wherein the mining comprises populating a structured database compiled for lung cancer from the structured and unstructured data, and wherein the analyzing of the patient record comprises analyzing from the structured database compiled for lung cancer; and presenting a report as a function of a result of the analyzing; further comprising the steps of: analyzing the structured database of structured patient information for a patient population to create a model of a similar patient with similar characteristics of the patient based on the patient record; and determining a progression of lung cancer in the patient based on the model, wherein the structured database of population-based structured patient information is compiled by mining data of population-based patients based on the domain knowledge base, wherein the data is stored in structured and unstructured formats. 16. A program storage device readable by a machine, tangibly embodying a program of instructions executable by the machine to perform method steps for screening for lung cancer, the method steps comprising: inputting patient-specific data into a patient record, the patient-specific data representing the patient; performing at least one lung cancer screening procedure on a patient, wherein at least one result from the at least one procedure is input into the patient record; mining data for the patient record based on a domain knowledge base specific to lung cancer, wherein the data of the patient record is stored in structured and unstructured formats, and wherein the mining comprises populating a structured database compiled for lung cancer from the structured and unstructured data; analyzing, with the machine, the patient record of the structured database with the domain knowledge base to determine whether the patient has indications of lung cancer; and presenting a report as a function of a result of the analyzing; further comprising the steps of: analyzing the structured database of structured patient information for a patient population to create a model of a similar patient with similar characteristics of the patient based on the patient record; and determining a progression of lung cancer in the patient based on the model, wherein the structured database of population-based structured patient information is compiled by mining data of population-based patients based on the domain knowledge base, wherein the data is stored in structured and unstructured formats. 17. The storage device as in claim 16 wherein the patient-specific data in the patient record includes information other than derived from an image, and wherein the analyzing comprises analyzing at least the information other than derived from an image with the domain knowledge base. 18. The storage device as in claim 16 wherein analyzing comprises making a probabilistic inference from information in the patient record as a function of the domain knowledge base. 19.
