Risk mapping Draw a basic map of the workplace, marking on it the machines, workstations and the substances or processes used. Record on the risk map any health problems reported by workers doing particular jobs. Repeat the exercise periodically and see if any problems become apparent. If cancer causing substances or processes are being used, investigate alternatives and, if this is not possible, safer work methods. Body mapping Draw two body outlines on a large piece of paper, one representing the front of a person, one the back. Get workers to write on where they feel pain. | Chapter 9 Cancer of the Lung Lynn A. Gloeckler Ries and Milton P. Eisner INTRODUCTION This study provides survival analyses for 201 067 histologically confirmed adult cases of lung cancer diagnosed from 1988 through 2001. Cases were obtained from the Surveillance Epidemiology and End Results SEER Program of the National Cancer Institute NCI . The SEER Program -- a sequel to two earlier NCI initiatives the End Results Program and the Third National Cancer Survey -- has evolved in response to the National Cancer Act of 1971 which requires the collection analysis and dissemination of data relevant to the prevention diagnosis and treatment of cancer. This chapter focuses on the influence of extent of disease histologic grade and demographic factors on lung cancer survival. MATERIALS AND METHODS The NCI contracts with medically oriented nonprofit institutions -- such as universities and state health departments -- to obtain data on all cancers diagnosed in residents of the SEER geographic areas. SEER collects data on all invasive and in situ cancers except basal cell and squamous cell carcinomas of the skin and in situ carcinoma of the uterine cervix. SEER selects participating institutions on the basis of two criteria their ability to operate and maintain a populationbased cancer reporting system and the epidemiologic significance of their population subgroups. At times registries will withdraw at times registries will be added. This analysis is based on data from 12 geographic areas which collectively contain about 14 of the total US population. The areas are the States of Connecticut Iowa New Mexico Utah and Hawaii the metropolitan areas of Detroit Atlanta San Francisco Seattle San Jose and Los Angeles and 10 counties in rural Georgia. Los Angeles contributed data for diagnosis years 1992 to 2001 the others for 1988 to 2001. To ensure maximal ascertainment of cancer cases each registry abstracts the records of all cancer patients in hospitals laboratories and all .
