Malignant Pleural Effusion Lung Cancer

I am interested in any information anyone may have who had malignant pleural effusion which is fluid in the chest cavity caused by a tumor in the lung. It is classified as stage IIIB inoperable.
I was diagnosed in July, 2003. I had to have 1 &1 1/2 liters of fluid drained from my chest cavity twice prior to the start of chemotherapy. The fluid returned a third time but went away after the first 2 months of chemo. I took Taxol and Carboplatin for 4 months, 12 treatments. CT scan after chemo showed cancer in remission. I take Iressa tablet daily. CT scans every 3 months still showing remission. The original diagnosis for this type of lung cancer was 6 months to 18 months. It will be a year on 7-31-2004.
