ABSTRACT
OBJECTIVE:
To analyze the clinicopathological characteristics and prognosis of patients with multilocular cystic renal neoplasm of low malignant potential and compare the clinicopathological characteristics of patients with multilocular cystic renal neoplasm of low malignant potential who underwent different surgical methods.METHODS:
Clinicopathological data and prognosis of patients admitted to Peking University Third Hospital from January 2010 to September 2023 were collected. Patients who underwent radical nephrectomy or nephron-sparing surgery and were pathologically diagnosed with multilocular cystic renal neoplasm of low malignant potential were identified. Based on the surgical methods, the patients were divided into radical nephrectomy group and nephron-sparing surgery group. The clinicopathological characteristics of the two groups were compared.RESULTS:
A total of 35 patients were enrolled in this study. The median age at diagnosis was 53.0 (39.0-62.0) years. Among the 35 patients, 23 were males (65.7%) and 12 were females (34.3%). Nine patients underwent radical nephrectomy (25.7%), while 26 patients underwent nephron-sparing surgery (74.3%). The clinical T-stage of 35 patients did not exceed T2a stage. The median operation time was 145.0 min, and the median estimated intraoperative blood loss was 20.0 mL. The median postoperative hospitalization days was 6.0 d. The postoperative pathological results did not indicate renal sinus invasion, sarcomatous change, adrenal invasion or lymph node invasion. Based on the surgical methods, the patients were divided into a radical nephrectomy group and a nephron-sparing surgery group. There was no significant difference in clinicopathological charac-teristics between the two groups. Except for one patient who was lost to the follow-up, all the other patients were followed up for 8-111 months, with a median follow-up time of 70.5 months. Only one patient died from non-cancer-specific reasons, other patients had no tumor metastasis or recurrence.CONCLUSION:
Patients with multilocular cystic renal neoplasm of low malignant potential have a good prognosis. There is no significant difference in clinicopathological characteristics of patients between nephron-sparing surgery group and radical nephrectomy group for multilocular cystic renal neoplasm of low malignant potential.Palavras-chave
