[Local relapse and single site of metastatic involvement of renal tumour. Prognostic factors and survival]

OBJECTIVE

To evaluate the clinical and pathological characteristics and survival in patients surgically treated for renal tumours that had local recurrence or metastasis to a single site.

MATERIAL AND METHODS

A retrospective study of 321 nephrectomies, evaluating the clinical and pathological variables in patients having local recurrence or metastasis to a single site, and who were treated surgically. Study and comparison of survival in the different groups.

RESULTS

The only factor found to have an independent influence on local recurrence is pathological stage. Local recurrence and the presence of metastasis to a single site have similar survival rates, both being statistically worse than in patients without metastasis at diagnosis, but better than in those having metastasis at diagnosis.

CONCLUSIONS

The presence of local recurrence has the same prognosis as a single excisable metastatic site, the prognosis being better than those initially with metastasis subjected to nephrectomy before receiving systemic treatment.

Feocromocitoma con trombo en cava

Pheochromocytoma, a paraganglioma of suprarenal location, is a catecholamine-secreting chromaffin cell tumour. Spread of these tumours to the vena cava is rare and the thrombus only reaches the right atrium in exceptional cases. We present the case of a patient who, without previous symptomatology, presented with a clinical picture of multiorganic dysfunction with primary manifestation of a suprarenal tumour with vascular spread to the right atrium affecting the right suprahepatic vein.
