Familial clear cell renal cancer

Note

Renal cell carcinomas (RCC) represent 85% of all primary renal tumors. In general, RCCs are sporadic tumors but cases of familial RCC have also been reported. If detected early and without metastases, the disease can be cured surgically with conservation of renal function. Both familial and sporadic cases have in common the presence of abnormalities involving chromosome 3, suggesting a primary role for this chromosome in RCC causation, particularly the clear cell type. An early gene rearrangement due to translocation may be a primary event. Loss of 3p and somatic mutation(s) in a tumor-surpressor-gene(s) on 3p (e.g.VHL) may be recurring events related to tumor progression

Inheritance

The inherited form of renal cancer is characterized by :
 , - the tumor is found at an early age compared to sporadic tumors (see below)
 , - the tumors are found frequently bilateral
 , - multiple occurrence.
 , Other (well known) classes of inherited renal cell carcinomas are:
 , 
  • the Von Hippel-Lindau syndrome, and , 
  • the Lynch syndrome II.
     , Also chromosome abnormalities may be related to inherited renal cancer.

    Note

    No phenotypic sign.

    Neoplastic risk

    Multiple and\/or bilateral nonpapillary renal cell carcinomas, with median age 45 yrs at diagnosis (range 18-79 yrs, most cases being between 35 and 55 yrs old).

    Treatment

    If the tumor is detected at an early stage the tumor can be surgical removed, without the lost of the renal function.

    Prognosis

    Depends on the stage of the tumor at the time of detection.

    Cytogenetics

    Note

    Clear-cell renal cell carcinomas are associated with chromosome 3 translocations and deletions of 3p.
