Trends of adult primary malignant renal tumors over 6 years

Objective: To assess the demographic and clinico-pathological trends, as well as the management options of adult patients with primary malignant renal tumors over 6 years. Methods: From July 2003 – July 2009, 55 adult patients with primary malignant renal tumors were treated in two teaching hospitals (Jordan University Hospital in Amman – Jordan and Al-Jumhory Teaching Hospital in Mosul – Iraq). Their data were reviewed retrospectively. Results: Of the 55 patients, 44 had renal cell carcinoma (RCC), eight patients had Transitional cell carcinoma (TCC) of the renal pelvis, two had Sarcoma and one Patient had primary renal lymphoma. Among patients with RCC: the mean age was 56 years, male to female ratio was 3:1. The most common presenting symptom was hematuria. Most of the patients were treated with radical nephrectomy, the clear cell subtype was predominant and most of the patients were diagnosed at stage T2. Regarding patients with TCC: mean age was 57 years, all were treated with radical nephro-ureterectomy and removal of bladder cuff, however (50%) of them developed TCC of urinary bladder within 12 months of radical nephro-ureterectomy. Conclusion: In our series of patients with RCC: there is a trend toward younger age at Diagnosis. We still encountered locally advanced and metastatic disease with a lower rate of incidentally Diagnosed tumors.With regard to patients with renal pelvis TCC: there are trends toward younger age affection, localized disease and early development of bladder TCC which indicate the importance of strict surveillance protocol.
