Surgical Management of Renal Cell Carcinoma: Comparisons of open and laparoscopic approaches.

OBJECTIVES

Renal cell carcinoma (RCC) is a leading urological malignancy with an age-standardised incidence rate of 2.5 per 100,000 per year in Oman. Experts are inclined towards the early detection and use of minimally invasive technology for the treatment of RCC. This study aimed report the shifting trend in the clinical presentation and management of RCC in Oman, comparing the outcomes of laparoscopic and open nephrectomy.

METHODS

This retrospective study included adult RCC patients from Sultan Qaboos University Hospital, Muscat, Oman, diagnosed from 2011-2022. Patient biodata, mode of presentation, diagnostic modality, final histopathology and details of treatment received including the perioperative outcomes were analysed.

RESULTS

A total of 56 patients that underwent surgical treatment for RCC, 34 underwent laparoscopic nephrectomy (LN) and 22 underwent open nephrectomy (ON). The mean ages in the LN and ON groups were 53.82 ± 13.44 years and 56.22 ± 15.00 years ( = 0.53), respectively. There were 47 patients of Omani descent and 9 patients were expatiates. The patients' mean tumour size was 6.25 ± 3.16 cm and 9.23 ± 5.20 cm for the LN and ON groups, respectively; 55.35% of the RCC cases were incidentally diagnosed. A trend towards LN was observed.

CONCLUSION

This study found a trend towards early diagnosis of RCC in Oman, with the majority of cancers being discovered incidentally in the studied period. LN is more commonly used in the surgical management of RCC with acceptable morbidity. These trends remain aligned with those found in the global literature on RCC.
