The interval between the diagnosis of XXXX and the development of effusions, with reference to the role of cytologic diagnosis.

@entity1 @entity1143 @entity0 @entity5 @entity843 @entity2
An analysis was made of the time lapse between the diagnosis of @entity5 and the development of an effusion in relation to the sex and age of the @entity1 and the site of the primary @entity5 . The total number of @entity1 studied was 254; of these, 171 @entity1 had a pleural and 83 @entity1 a peritoneal effusion. In the total group, sex distribution was two @entity1 to three @entity1 : about equal in the @entity1143 group and about two @entity1 to nine @entity1 in the @entity843 group, with the latter ratio reflecting the large number of primary malignant processes in the breast and ovaries. The average age at the time of the effusion, whether it was located in the pleural or in the peritoneal cavity, was about 55 years. This figure was roughly 60 years for @entity1 and 51 years for @entity1 . The nine-year average age difference between sexes can be explained by the size of the four largest groups of different primary malignant localizations and their sex distribution. The interval between the discovery of the primary @entity5 and the first fluid sample was longer for @entity1 with a @entity1143 (average of 77.0 weeks) than for @entity1 with @entity843 (average of 54.5 weeks). The longest interval was seen in the @entity0 group, with the shortest interval in @entity2 @entity1 . The interval was significantly longer for @entity1 , being 111.9 weeks for @entity1143 and 57.9 weeks for @entity843 (average for both sites of 88.7 weeks). In 30.7% of the @entity1 , the primary @entity5 was discovered at the same time or later than the effusion; in @entity1 with @entity2 , a strikingly higher percentage of 53.0% was found. In this respect, the cytologic diagnosis of effusions is of great importance not only for the detection and proper identification of a malignant process but also as an indicator of the life expectancy of a @entity1 .
