An attempt is made to elucidate the occurrence of .'lung cancer in associ -ation wi th ,cigarette snoking and air polution carcinogens. Statistica1 <lata record an incre· aze o:f morbidity rates o:f lung cancer :froa 17,J in 1962 to 30.02 in 1972, men being substantia1ly more afflicted than woaen,in a ratio o:f 5,6 :1.Urban population su:f:fers more ;predominautly males 1 which is attributed to greater . cigarette smokinR as well as working in Oi:fices with smokers and biologi-ca1 sex dif:ferences.Comparisons bet­ween smokers in towns and villages reveal equa1 morbidity rates in botts groups.This fact gives grounds for the assumption that cigarette smo­king is the leading carcinogenic :factor as compared to air pollution carcinogens in our country. 'MULTIPLE PRIMARY CANCERS AS RECORDED BY THE CANCtR REGISTRY OF SLOVENIA A PROBLEM OF RELIABILITY B. RAVNIHAR ond V. POMPE KIRN,Institute of Oneology, Ljubljana, Yugoslavia The cases recorded by the S !ovene Cancer Registry in the post years as new cancers occuring synchronously or nonsynchronously with one or more other primary can-:ers in the same individual 1 have been thoroughly reviewed. According to the preliminory doto for the yeor 1971, e.g. among the total of 3959 new cancers registered in this year, 137 (3,5%} such coses were 'bund, 62 in moles .(3, 1%) ond 75 in females (3, 8%). Strictly opplying the criterio estoblished by Warren and Gates, and respecting the requirement of Moertel, i. e. to el im inate the cases verified by cytology only, the above given number and Workshop 1 O • Cancer epldemiology rate of multiple cancer coses would be reduced to 81, i.e. 2.1% (1,5% in males and 2,7% in femoles) of the corrected total number of newly diagnosed cancers in the year 1971 . The median age when the second primory cancer has been diagnosed was 70 yeors in moles and 65 in fe­moles. The incidence of multiple cancers in the pop­ulation covered by the Registry, occording to the site and tissue of origin, and the average interval between consecutive neoplasms will be presented ond discussed. Analysing the coses recorded as multiple primorrneoplasms it wos felt that in certain instances in selecting these cases for further studies one con rely olso on the cytological findings ond the clinical course of the diseose. SISTEMA NACIONAL DE CONTROLE DO CANCER Joao Sampaio Goes Junior Faculdade-de Medicina da Univer sidad, de Sao Paulo Sao Paulo - S. P. BRAZIL The Federal office for cancer research and control in Brazil, presently develops a nationalwide program of early detection of the desease, aiming at the establishment of the establishment of the basic conditions for the control of the deseas�. This program, nomed SISTEMA NA­CIONAL DE CONTROLE DO CANCER, is structu­red into the four sub-systems: Diagnosis Info-processing Epidemiology Therapeutic SISTEMA DE DIAGN6STICO DE CANCER; SISTEMA DE REGISTRO DE CANCER; SISTEMA DE EPIDEMIOLO GIA DE CANCEH; SISTEMA DE THATAMENTO DE CANCER; The syetem o1 Oiagnosis is com­posed of d1agnosis modules, spread among the official and private entities accord­ing to operational agreeements.
