| Small Cell Lung Cancer | Common |  malignant pleural effusion |
| Epithelial Ovarian Cancer | Common | |
| Cervical Cancer | Rare | effusion more common than frank pleural involvement |
| Hodgkin's Lymphoma | Uncommon |  Pleural effusions occur much more often than direct invasion and typically are not malignant (thus do not confer a worse prognosis). |
