General Information
Renal cell cancer, also called renal adenocarcinoma, or hypernephroma, can
often be cured if it is diagnosed and treated when still localized to the
kidney and to immediately surrounding tissue. The probability of cure is
directly related to the stage or degree of tumor dissemination. Even when
regional lymphatics or blood vessels are involved with tumor, a significant
number of patients can achieve prolonged survival and probable cure.[1] When
distant metastases are present, disease-free survival is poor, although
occasional selected patients will survive after surgical resection of all known
tumor. Because a majority of patients are diagnosed when the tumor is still
relatively localized and amenable to surgical removal, approximately 40% of all
patients with renal cancer survive 5 years. Occasional patients with locally
advanced or metastatic disease may exhibit indolent courses lasting several
years. Late tumor recurrence many years after initial treatment occasionally
occurs.
Renal cell cancer is one of the few tumors in which well-documented cases of
spontaneous tumor regression in the absence of therapy exist, but this occurs
very rarely and may not lead to long-term survival. Surgical resection is the
mainstay of treatment of this disease. Even in patients with disseminated
tumor, locoregional forms of therapy may play an important role in palliating
symptoms of the primary tumor or of ectopic hormone production. Systemic
therapy has demonstrated only limited effectiveness.
