  1. UROEPITHELIAL TUMORS TERRENCE C. DEMOS, MD DEPARTMENT OF RADIOLOGY LOYOLA UNIVERSITY MEDICAL CENTER

  2. UROEPITHELIAL TUMORS INCIDENCE • URINARY BLADDER(94% OF ALL UROEPITHELIAL TUMORS) • RENAL PELVIS • (5% OF ALL UROTHELIAL TUMORS) • URETER • (1% OF ALL UROTHELIAL TUMORS)

  3. UROEPITHELIAL TUMORSINCIDENCE • URINARY BLADDER • (50 THOUSAND NEW CASES BLADDER CA/YEAR IN USA) M:F 3:1 • RENAL CELL CARCINOMA OF KIDNEY • (15,000 THOUSAND NEW CASES/YEAR IN USA)

  4. UROEPITHELIAL TUMORSRISK FACTORS • SMOKING • ANALGESICS • PHENACETIN • CYCLOPHOSPHAMIDE • OCCUPATIONAL CARCINOGENS • COAL, ASPHALT, TAR, PETROCHEMICALS, PLASTICS • PAPILLARY NECROSIS • FAMILIAL CANCER SYNDROMES • HEREDITARY NONPOLYPOSIS COLORECTAL CANCER (LYNCHII)

  5. UROEPITHELIAL TUMORS COLLECTING SYSTEM DEVELOPES FROM FETAL MESONEPHROS UROEPITHELIAL CA: TRANSITIONAL CELL OR SQUAMOUS CARCINOMA DERIVED FROM • MESODERM • EPITHELIAL TISSUE RENAL PARENCHYMA DEVELOPES FROM METANEPHRIC BLASTEMA RENAL CELL CA: ADENOCARCINOMA DERIVED FROM • TUBULAR EPITHELIUM

  6. UROEPITHELIAL TUMORS • 90% TRANSITIONAL CELL • 9% SQUAMOUS CELL • >1% • ADENOCARCINOMA • SARCOMA • UNDIFFERENTIATED • BENIGN MESODERMAL

  7. UROEPITHELIAL TUMORTRANSITIONAL, SQUAMOUS, AND SARCOMA ELEMENTS

  8. TRANSITIONAL CELL CARCINOMA

  9. TRANSITIONAL CELL CARCINOMA CLASSIFICATION PAPILLARY NONPAPILLARY

  10. TRANSITIONAL CELL CARCINOMA • PAPILLARY TYPE 80% • 50% ARE INFILTRATIVE MALIGNANCIES • NONPAPILLARY TYPE 20% • ALL CONSIDERED TO BE MALIGNANT

  11. PAPILLARY CARCINOMAINVASIVE VERSUS NONINVASIVE

  12. NONPAPILLARY (FLAT) CARCINOMAINVASIVE VERSUS NONINVASIVE

  13. TRANSITIONAL CELL TUMORS • PATHOLOGIC CLASSIFICATION RANGE • WELL DIFFERENTIATED PAPILLOMA (GRADE 1) • MALIGNANCY RANGES FROM LOW-GRADE AND SUPERFICIAL TO HIGH-GRADE AND INVASIVE

  14. UROEPITHELIAL TUMORSIMAGING MODALITIES • EXCRETORY UROGRAM • SONOGRAPHY • RETROGRADE PYELOGRAM • COMPUTED TOMOGRAPHY • ANGIOGRAPHY

  15. TRANSITIONAL CELL TUMORS GROSS APPEARANCE ON IMAGING STUDIES • SINGLE LESION • SMALL AND PAPILLARY TO BULKY AND SESSILE • MULTIPLE DISCRETE LESIONS • DIFFUSE AND CONFLUENT LESIONS

  18. TRANSITIONAL CELL CAPAPILLARY TYPESTIPPLED APPEARANCE

  19. TRANSITIONAL CELL CARCINOMA • TENDENCY TO BE MULTICENTRIC AND BILATERAL • BILATERAL IN UP TO 10% OF PATIENTS • (SYNCHRONOUS OR METACHRONOUS) • UP TO 1/2 OF PATIENTS WITH CA URETER OR PELVIS WILL DEVELOP BLADDER CARCINOMA

  20. MULTIPLE TRANSITIONAL CELL CARCINOMAS

  21. TRANSITIONAL CELL CARCINOMA PROGNOSIS • PATIENTS WITH A RENAL PELVIC PAPILLOMA • 1/4 WILL DEVELOP A CARCINOMA • PATIENTS WITH MULTIPLE PAPILLOMAS • 1/2 WILL DEVELOP A CARCINOMA • PATIENTS WITH BLADDER/URETER TRANSITIONAL NEOPLASM • 1/3 ALREADY HAVE ANOTHER BLADDER TCC

  22. SQUAMOUS CARCINOMA

  23. SQUAMOUS TUMORS • ASSOCIATED WITH INFECTION AND STONES, LEUKOPLAKIA • SQUAMOUS METAPLASIA OF TRANSITIONAL EPITHELIUM • MOST ARE SOLITARY • CAN BE PAPILLARY OR SESSILE • HIGHLY INVASIVE • OVERALL, POOR PROGNOSIS

  24. HEMATURIASQUAMOUS CARCINOMA INITIAL CT CT 8 MONTHS LATER

  25. SQUAMOUS TUMORS • DIFFICULT TO RECOGNIZE DUE TO UNDERLYING DISEASE • INFECTION • STONES • OFTEN INVASIVE OR METASTATIC AT TIME OF DIAGNOSIS • PREDOMINENTLY EXTRALUMINAL • MAY APPEAR AS URETERAL STRICTURE

  26. DISTAL URETERAL UROEPITHELIAL TUMORSQUAMOUS CARCINOMA

  27. UROEPITHELIAL NEOPLASMS IMAGING

  28. UROEPITHELIAL TUMORSIMAGING COLLECTING SYSTEM CALYCES INFUNDIBULI PELVIS URETERS BLADDER

  29. UROEPITHELIAL TUMORS • RENAL PELVIS

  30. TRANSITIONAL CELL CARCINOMA INVADES KIDNEY

  31. LARGE, INVASIVE UROEPITHEAL TUMOR RENAL PELVIS

  32. TRANSITIONAL CELL CARCINOMARENAL PELVIS
