Background:
The etiology of pleural effusion remains unclear in nearly 20% of cases. One way to diagnose malignancy is
by doing pleural fluid cytology. There are factors that influence the yield of pleural fluid cytology and one of them is appropriate and timely fixation of samples. Currently, there is no local consensus regarding the timing with which the specimen should be fixed.
Objective:
The study aims to compare the yield of malignancy between early fixation versus usual fixation of pleural fluid
samples, meaning there is no set time for fixation to be done.
Methodology:
The study employed a prospective cross-sectional research design. All patients with pleural effusion who
fulfilled the criteria set by the study were included. Two sets of pleural fluid samples were collected amounting to 20cc each. First sample was assigned as Bottle #1 and placed immediately with fixative while the second sample was assigned as Bottle #2. Bottle #2 underwent routine fixation which follows no fixed or standard time of fixation. The time difference between the fixation of two sample groups greatly varied with Bottle #1 fixed immediately right after collection while Bottle#2 depends on the time it will be processed by the laboratory personnel. Both samples were submitted for cell block and cell cytology reading.
Results:
Characteristics of the 55 patients included in the study showed age group range from 41 to 65 years of age, with 27 male and 28 female patients. Only one third had history of smoking. There were 21.82% who had family history of cancer and with and suspicious mass on chest radiograph. Out of 55 patients, 29 patients had history of previous diagnosis of cancer, 23 had recurrent pleural effusion, and 28 had chest radiograph with suspicious nodules. Based on gross appearance, there were 20 serous and 21 sanguineous pleural fluid noted. Mean cell count was high (1,115.50 ± 741.02) with lymphocytic predominance (82.56 ± 24.46). Elevated protein concentration (5,388.25 ± 8,230.46) and LDH (484.17 ± 248.72) were noted. Glucose (8.78 ± 6.68 mmol/L) was low. There were 21 patients who had high WBC, 24 with high protein and 16 with elevated LDH. There were 3 patients who were positive for AFB and none for KOH. Comparative analysis showed that the pleural fluid samples assigned to the routinely fixed group which were handed to the nurse after thoracentesis, then forwarded to the laboratory through a ward laboratory aide or patient watcherfor fixation with with 95% alcoholby thelaboratory personnel significantly had a longer duration of 406.62 minutes as compared to immediately fixed at 12.27 minutes (P<0.01). For diagnosis of malignancy, significantly more cases were diagnosed in the immediately fixed group with 36.36% cases versus 18.18% (p=0.016).
Conclusion
Among patients with suspected malignant pleural effusions, early fixation of pleural fluid samples resulted in
higher histopathology yields as compared to those fixed after going through the routine fixation.

3.Malignant Pleural Effusion: Medical Approaches for Diagnosis and Management.
Tuberculosis and Respiratory Diseases 2014;76(5):211-217
Malignant pleural effusions (MPEs) are the second leading cause of exudative pleural effusions after parapneumonic effusions. In the vast majority of cases, a MPE signifies incurable disease associated with high morbidity and mortality. Considerable advances have been made for the diagnosis of MPEs, through the development of improved methods in the specialized cytological and imaging studies. The cytological or histological confirmation of malignant cells is currently important in establishing a diagnosis. Furthermore, despite major advancements in cancer treatment for the past two decades, management of MPE remains palliative. This article presents a comprehensive review of the medical approaches for diagnosis and management of MPE.

BACKGROUND: Most of malignant pleural effusions are serous but 8-33% of them are bloody. We wanted to evaluate the relationships between gross appearance and pleural CEA level or results of histocytology in malignancy associated pleural effusions. We also tried to reevaluate the meaning of CEA measurement in histocylogically proved or unproved malignancy associated pleural effusions. METHODS: We studied 98 cases of malignancy associated pleural effusions, 50 cases of histocylologically proven malignant effusions and 48 cases of histologically unproven paramalignant effusions. We had observed gross appearance and conventional laboratory values and CEA levees for pleural effusions. RESULTS: 44.9% of malignancy associated effusions were bloody(63.6% of bloody effusions were histstocytologically proven malignant effusion). 65.0% of malignancy associated pleural effusions which have RBCs numbers over 100,000/mm3 were cytologically proven malignant effusions. 72.7% of cytologically proven malignant effusions had increased pleural fluid CEA level over 10 ng/ml. 58.2% of cases with pleural CEA over 10ng/ml had positive results in pleural histocytology. There was no definable relationships between pleural fluid CEA elevation and RBCs numbers and results of pleural fluid cytology. CONCLUSION: About half of the cases with malignancy associated pleural effusions were bloody. Histocytologically proven malignant effusions were more common in bloody effusion than non-bloody effusion (63.6% Vs 38.9%). But increased red blood cell numbers was not associated with positivity of pleural histocytology. Pleural fluid CEA elevation(over 10 ng/ml) was not correlated with positive pleural histocytology. But pleural fluid CEA elevation was rare In nonmalignant pleural effusions, and than pleural CEA measurement in uncertain pleural effusions maybe helpful to distinguishes its origin.

We report a case of adenocarcinoma detected in the right pleural effusion of a 75-year-old woman. Investigations failed to reveal the site of the primary lesion, and the case was treated as primary unknown cancer. The pleural effusion disappeared after chemotherapy; however, as there was serious bone marrow suppression, the clinical course was observed at an outpatient clinic without chemotherapy. A search for the primary lesion was repeated, but it was not found. One year after first admission, a chest X-ray showed left pleural effusion. Adenocarcinoma was detected in the effusion and a tumor mass obtained from the pleural cavity. Ovarian cancer was diagnosed based on the histological, serological and MRI findings. Thus, this was a rare case of ovarian cancer in which the diagnosis was confirmed by repeated evaluation and in which the initial diagnosis had been primary unknown cancer with malignant pleural effusion only.

9.Cytogenetic Study in Suspicious Cases of Malignant Pleural Effusion.
Cancer Research and Treatment 2002;34(3):234-238
PURPOSE: This study was performed to detect malignant cells in suspicious cases of malignant pleural effusion by cytogenetic analysis. MATERIALS AND METHODS: Eleven cases with pleural effusion were included in this study. Cells in pleural effusion were treated by direct, or short term, culture to prepare chromosomes. To analyze chromosomes, the G-banding method was used. RESULTS: Chromosome preparations succeeded in 10 cases. 5 cases had normal karyotypes, but in 2 of these cases malignant cells were detected on cytological examination. The other 5 cases had abnormal chromosomes, but on cytological examination showed normal cell appearances. CONCLUSION: Cytogenetic analysis of pleural effusions is not used routinely, but is more sensitive than the cytological examination of malignant pleural effusions. So, chromosome analysis is a good diagnostic tool, when chromosomal abnormalities are detected in an effusion. If a combination of cytology and cytogenetic study are used, the chance of detecting malignant cells in pleural effusion will be higher, and then more invasive diagnostic procedures, such as thoracoscopy or thoracotomy, could be avoided.

PURPOSE: To evaluate the diagnostic accuracy of CT in the differential diagnosis of tuberculous and malignant pleural effusion whether or not lung lesions are present, and to investigate the CT findings used for this differential diagnosis. MATERIALS AND METHODS: This study involved 30 patients with tuberculous pleural effusion (mean age, 44.6 years; M:F=19:11) and 20 with malignant pleural effusion (mean age, 57.2 years; M:F=10:10). All 50 patients underwent enhanced CT chest scans, and the respective conditions were pathologically confirmed. Two radiologists unaware of the pathologic results and distribution of patients reviewed these scans retrospectively and independently. They recorded the presence or absence of helpful lung lesions, CT findings of pleural effusions, their diagnoses, and the degree of confidence of their diagnoses. RESULTS: Among the total of 100 answeres, helpful long lesions were found in 57 cases. Fifty-three of 57 diagnoses (93%) were correct and 26 cases (46%) were diagnosed with a high degree of confidence. Thirty-two of 43 cases (74%) without helpful lung lesions were correct and 11(26%) were diagnosed with a high degree of confidence. All diagnoses made with a high degree of confidence were correct, even in cases without helpful lung lesions. Frequent CT findings in tuberculous pleural effusion included diffuse pleural thickening, enhancement of pleura, deposition of extrapleural fat, and pleural calcification; in malignant pleural effusion, nodular pleural thickening, pleural thickening over 1cm and associated lymphadenopathy were frequent. Mediastinal and circumferential pleural, as well as fissural involvement, were seen in both effusions; there were no statistical differences. CONCLUSION: In most cases, CT provided correct differential diagnosis between tuberculous and malignant pleural effusion. It can help determine the nature of associated lung and pleural lesions, and specific findings of the latter, and can accurately differentiate tuberculous and malignant pleural effusion.
