[Renal adenocarcinomas associated with other malignant neoplasms]

The renal adenocarcinoma is not a frequent tumour within the scope of multiple neoplasias, at least in the clinical series. Conversely, it appears at a higher relative rate in the post-mortem series. This paper submits a review of renal adenocarcinoma associated in life to other malignant neoplasias, enumerating their major clinical and epidemiological data. Also, it reviews the literature with regard to frequency and etiology, applying the data to our series. The paper concludes that hypernephroma is not a tumour frequently associated with others in life, given its tendency to be secondary to other primary ones, therefore its development depending on survival to the initial tumour. It also emphasizes the need for adequate anamnesis aimed to detect multi-cancer syndromes and the etiology of multiple neoplasias. Further studies are needed to understand the scope of multiple neoplasias and their relative risk.
