Objectives: To determine the outcome of patients with clinically organ-confined prostate cancer undergoing radical retropubic prostatectomy for cure and incidentally discovered concurrent low-grade non-Hodgkin's lymphoma at time of surgery.
Methods: From September 1986 to September 1997, 4319 patients underwent radical retropubic prostatectomy at our institution. The records of 10 patients incidentally diagnosed to have low-grade non-Hodgkin's lymphoma at the time of radical prostatectomy were retrospectively reviewed.
Results: Of 4319 patients requiring radical prostatectomy, 10 (0.2%) were found to have low-grade non-Hodgkin's lymphoma. All 10 men had an uneventful postoperative course. Two patients subsequently developed progression of lymphoma, one of whom required treatment. One patient died of sepsis associated with his lymphoma and 1 patient died of an unrelated malignancy (lung cancer), both 7 years following surgery. Two patients developed biochemical prostate-specific antigen recurrence. The remainder of men were free of prostate cancer recurrence and experienced no progression of lymphoma at an average of 45 months (range 12 to 142).
Conclusions: Patients with organ-confined prostate cancer, who are candidates for radical prostatectomy, experience long-term prostate cancer-free survival in the face of incidentally diagnosed low-grade lymphoma. Because the management of most incidentally discovered low-grade lymphomas is expectant, patients discovered at surgery to have this clinical entity should not be denied radical prostatectomy.
