Abstract

Introduction: Retroperitoneal tumours (RTs) in adults are a rare heterogeneous group of neoplasms arising from the retroperitoneal space. RTs’ clinical manifestations are nonspecific and depend on their anatomical positioning and relation with bordering structures.

Our study aimed to retrospectively evaluate our patients’ diagnosis, length of hospital stay, disease-free period and postoperative metastasis occurrence. Methods: From 2011 to 2019, fifteen suspected RT resections were performed at our centre.

Retrospective analysis of patients’ hospital stays, follow- up, histological and immunological tumour profile, and metastasis occurrence/ re-occurrence was performed. Result: All of the 15 (100%) patients were males.

The average age of our patients was 44 years (SD ± 11.2 years), average hospital stay was 7.4 days (SD±3.4 days) (Tab.1). All resected tumours underwent histological and immunological evaluation.

Based on histological examination of the resected tumours, nonseminomatous germ cell tumours were present in 12 (80%) patients – including teratoma in 4 (26.6%) patients, seminoma in 2 (13.3%) patients, and malignant B-cell lymphoma in 1 (6.6%) patient. The average patient follow-up was 42.7 months (SD±31.4.9 months).

Complete remission after the surgery was achieved in 11 (76.9%) patients, and 2 (13.3%) patients were lost in follow-up. Conclusion: RT is a rare heterogeneous group of neoplasm.

The patient’s prognosis dramatically depends on the type of tumour, metastasis occurrence and re-occurrence, and the surgeons’ ability to resect the tumour completely.
