Symptoms & Signs
CP of RCC
- Incidental
- Incidental (50%)

- Symptomatic
CP of RCC
- Main Symptoms
Hematuria (50%) - Loin pain (40%) - Mass 30%.
CP of RCC
- Old CLassic Triad
- Old classic triad (pain, hematuria, and mass) in 10%.
CP of RCC
- Varicocele & Edema
Non-reducing varicocele or bilateral lower limb edema.
CP of RCC
- Mets
Metastatic symptoms (25%):
A. Lungs (75%).
B. Bones (20%).
C. Liver.
D. Brain.
CP of RCC
- Paraneoplatsic Syndrome
CP of RCC
- Internist or Radiologist?
- RCC used to be the internist’s tumor.
- May now be the radiologist’s tumor, as >60% are incidental.
Signs of RCC
- Abdominal Mass

Incidence of RCC with Venous Thrombus
- 4-10%
- More common on right side.
CP of RCC with Venous Thrombus
- 10- 25% extension above the hepatic veins.
- One third are metastatic.
TTT of RCC with Venous Thrombus
- Surgery can provide long tenn survival in suitable candidates with no metastas:
- Not difficult.
- Pull back the thrombus into RV and side clamp the IVC.
- Laparoscopically possible.
TTT of Metastatic RCC
- Chemo & Radio
NOOO
- RCC is chemo-refractory and radio-resistant!
TTT of Metastatic RCC
- Immunotherapy
TTT of Metastatic RCC
- Allogeneic stem cell transplantation
Has significant morbidity
“The standard of care for advanced RCC is the best available clinical trial”.
Ok Sir
Targeted therapy for RCC
- Antiangiogenic Drugs
- mTOR Inhibitors
Antiangiogenic Drugs in RCC
Tyrosine kinase inhibitors (TKIs):
- block the intracellular domain of the VEGFR (e.g., Sunitinib, Sorafenib, Axitinib).
Monoclonal antibody:
- bind circulating VEGF and prevent it from activating the VEGFR (e.g., Bevacizurab).
mTOR Inhibitors in RCC
Temsirolimus
Etiology of Renal Pelvis Tumors
Occupational RF for Renal Pelvis Tumors
- Chemical.
- Leather.
- Printing.
- Gasworks.
- Rubber.
- Sewage works.
- Plastic
Pathology of Renal Pelvis Tumors
- Malignant
- Transitional Cell Carcinoma (TCC) (The most common).
- Squamous Cell Carcinoma (SCC)-
- Adenocarcinoma.
