Impact du délai avant prise en charge par néphrectomie partielle d’une tumeur du rein localisée
Bulletin du Cancer(2023)
摘要
Partial nephrectomy is the treatment of choice for small localized renal tumors. In case of doubt, a biopsy can confirm the diagnosis. The aim of this study was to evaluate the impact of a delayed time to partial nephrectomy on cancer development.Our single center study enrolled localized renal tumor patients who underwent a partial nephrectomy between 2015 and 2020; the collected data were included in the uroCCR prospective database. The histopathological stage of the tumors and the recurrence rate in patients treated with surgery >90 days after diagnosis were investigated. The impact a preoperative biopsy on was also explored. Statistical significance was tested using Student's t-test and Chi-squared test (SPSS software).The cohort consisted of 179 patients, among which 41 (23 %) received a preoperative biopsy. 89 patients (50 %) were treated surgically >3 months after diagnosis. The median time to nephrectomy was 86 days (13-1 037). A delayed time to surgery did not lead to significantly higher recurrence rates (P=0.66). Preoperative biopsy led to a doubling time to surgery (P<0.001) but was neither correlated to a more severe tumor stage (P=0.944) nor to a higher recurrence rate (P=0.08). Tumor growth was not significantly different with or without the presence of a biopsy (P=0.122).Our data evidence that a substantial delayed time to partial nephrectomy does not result in a negative impact on cancer prognosis in localized renal tumor patients.
