Summary

The purpose of this study is to determine the effects (good or bad) that sildenafil (Viagra) has on patients with slow growing Waldenstrom's macroglobulinemia (WM). Sildenafil blocks the function of several proteins necessary to the survival of certain types of cancer and laboratory tests have shown that it can destroy WM cells.

Detailed description

* Sildenafil will be given orally (at home) at a reduced dose for the first week, then each week for 3 more weeks, the dose will be increased. If the patient has no major side effects, then they will receive the maximal dose for 2 years. If they have major side effects, then the dose of the drug might be lowered or the drug stopped. * Sildenafil will be continued until their is disease progression or serious side effects. * While patients are receiving sildenafil, they will be seen in the clinic on months 1,2,9,15 and 21 for blood tests and a subject questionnaire. They will also be seen on months 3,6,12,18 and 24 for a physical exam, blood test, physical assessment test, CT scans of chest, abdomen and pelvis, and a subject questionnaire. * At the end of the study (month 24) a physical exam, blood tests, physical assessment test and a questionnaire will be conducted. * Follow-up includes clinic visits at month 27,33,39 and 45 for blood tests and a questionnaire as well as visits at month 30,36,42 and 48 for physical exam, blood tests, physical assessment test, bone marrow aspirate and biopsy, CT scans of chest, abdomen and pelvis, and a questionnaire.
