This study explores the relationship between pleural fluid appearance and the results of chemical and cytological analyses in a group of patients with recurrent symptomatic pleural effusions and a diagnosis of cancer. Methods Medical records were reviewed from all 390 patients who were diagnosed with cancer who underwent thoracentesis before placement of an intrapleural catheter IPC between April 2000 and January 2006. Adequate information for data analysis was available in 365 patients. The appearance of their pleural fluid was obtained from procedure notes dictated by the pulmonologists who had performed the thoracenteses. The patients were separated into 2 groups based on fluid appearance non-bloody and bloody. Group differences in cytology interpretation were compared by using the chi square test. Cellular counts chemical laboratory results and survival after index procedure were compared by using the student s t test. Results Pleural fluid cytology was positive on of the non-bloody effusions and on of the bloody ones. The number of red blood cells X 103 al_ vs. X 103 gl_ and LDH values 1914 lU dl vs. 863 lU dl were statistically higher in bloody pleural effusions. Conclusion The presence or absence of blood in pleural effusions cannot .
