Abstract
Aim: Retrorectal tumours are a rare and complex entity in adults and children. They present a varied symtomatology and their treatment is very different according to their histology. We aimed to evaluate our experience of tumors of the retrorectal space.
Method: 40 patients with retrorectal tumours were divided into two groups according to age. The variables analysed were: sex, signs and symptoms, complementary examinations, surgical approaches, adjuvant therapies, pathological analyses, recurrence and survival.
Results: Symptoms across the 30 adults varied, back pain (18) was the most common. Surgical intervention was performed on 20 patients, the rest were candidates for other treatments: 5 metastatic disease, 2 lymphomas and 2 Ewing tumour. The most common surgical approach was posterior, with 10 cases (50%). 70% of adult tumours were malignant, with chordoma (30%) and metastases (20%) being the most common lesions. The most frequent benign lesion was hamartoma (10%). The 1 and 5-year mortality rates were 23.8% and 38.1%, respectively. In the paediatric group, 3 patients were diagnosed in utero. The symptoms among childred varied and all were operated upon. The most frequent tumour was teratoma. Overall mortality was 20%.
Conclusions: Given their complexity, these tumours should be addressed by experts and all treatment options must be contemplated. They continue to present a challenge, above all in malignant tumours where the tumour cannot be controlled at a loco-regional level.
