The_Oncologic_Features_of_Retroperitoneal_Masses.pdf | 1.07 MB |
OBJECTIVE: The nature and oncologic features
of the retroperitoneal masses are still ill defined. In this retrospective
study
we attempted to investigate the clinical characteristics of this masses.
MATERIAL-METHODS: We reviewed the
record of 28 patients (average age: 45.79; range: 17-90) who underwent surgery due
to retroperitoneal masses, between November 2001 and Augusts 2007.
RESULTS: Nineteen patients (mean age: 46.89) had the primary retroperitoneal
origin, while the remaining patients (mean age: 38.11) were secondary. The average
diameter of the masses was 8.87cm (range: 3-25). The masses involved nearby
organs; the urinary system in16 patients, vascular in 5 and posas muscle in 3 patients.
The origin of the primary lesions were from retroperitoneal organs in 4 patients,
from muscular in 2, from nervous system in 2, from mesenchymal in 2, from undifferentiated
origin in 4 and the remaining patients were from various malignancy. The secondary
cases was from testicular origin except in one. The surgical approach were applied
for all cases and the complete resection were achieved in 19 (67,85 %) patients,
while the remaining patients had residual masses. The majority of patients with
residual mass were from those whom their masses were from retroperitoneal origin.
CONCLUSION: Retroperitoneal mass seems to be mainly originated from retroperitoneal
space. Although the surgical approach is the main
valid choice, it is not of satisfactory results and the prognosis of these masses
are fairly poor
