Abstract
Renal cell carcinomas (RCC) represent a group of heterogeneous tumors whose classification has greatly evolved since 1981. The latest update in 2022 classifies all renal cell carcinomas into six categories according to their morphology or the detection of specific molecular alterations. Molecular disassembly of renal cell carcinomas with papillary features has enabled the identification of new entities characterized by a specific molecular alteration, such as Fumarate Hydratase (FH) deficient RCC, TFE3-rearranged RCC or TFEB-altered RCC. This new classification allows for a more accurate diagnosis but requires a thorough knowledge of the genomic alterations to search for with immunohistochemical or molecular biology techniques. According to the new WHO 2022 classification, papillary renal cell carcinoma (PRC) type 1 or type 2 classification is no longer recommended. A classification based on nucleolar ISUP grade must be preferred: low-grade PRC (ISUP 1-2) or high-grade PRC (ISUP 3-4). The other prognostic factors remain the same: the pTNM stage, lymphovascular invasion, and the presence or absence of dedifferentiated areas referring to sarcomatoid or rhabdoid features. Of note, the presence of necrosis is not currently recognized as a poor prognostic element for this type of carcinoma. The diagnosis of high-grade PRC is from now on a diagnosis of exclusion. It can only be sustained after having ruled out TFE3-rearranged RCC, TFEB-altered RCC, and FH-deficient RCC. For clinicians, the diagnosis of PRC implies suggesting an oncogenetic consultation to screen for an associated genetic tumor syndrome regardless of the patient's age.

Abstract
Managing a malignant renal tumor requires, first of all, a reflection on the necessity of its treatment. It must consider the renal function, altered at the time of diagnosis in 50% of cases. The treatment method chosen depends on many factors, in particular, the predicted residual renal function, the risk of chronic kidney disease, the need for temporary or long-term dialysis, and overall long-term survival. Other factors include the size, position, and number of tumors and a hereditary tumor background. When a renal-sparing management alternative is available, total nephrectomy should no longer be performed in patients with small malignant renal masses (cT1a). This may consist of surgery (partial nephrectomy or lumpectomy), percutaneous thermo-ablation (by radiofrequency, microwave, or cryotherapy). In patients with limited life expectancy, imaging-based surveillance may be proposed to suggest treatment in case of local progression. Good coordination between urologist, radiologist, nephrologist, and sometimes radiotherapist should allow optimal management of patients with a malignant renal tumor with or without underlying renal failure.

Abstract
BACKGROUND Treatment landscape for advanced renal cell carcinoma (aRCC) has evolved quickly and few data about the real-world treatment patterns are available. This study aimed at describing the real-world treatment patterns and effectiveness of all systemic treatments available for aRCC in first and second-line treatment. MATERIALS AND METHODS A cohort of patients initiating a first-line systemic treatment for aRCC in 2016 was extracted from the French nationwide healthcare insurance system database (SNDS). The first-line treatment initiation date constituted the index date and patients were followed until death, loss to follow-up, or December 31, 2019, whichever occurred first. aRCC was identified using hospital diagnosis, long-term disease, or renal biopsy before index date. All analyses were performed for first and second-line treatment. Overall survival (OS) and time-to-next treatment or death (TNT-D) were estimated using Kaplan-Meier approach. RESULTS In 2016, 1629 patients initiated a first-line treatment for aRCC. Most of them were male (75.9%) and the median age was 67 years. Most of patients (91.7%) had received a tyrosine kinase inhibitor as first-line treatment, mainly sunitinib (64.4%), and 53.5% received a second-line, among which 43.7% nivolumab. Median OS (95% confidence interval [CI]) was 20.7 (95% CI:18.2-22.4) months from first-line treatment initiation and 15.4 (13.9-17.5) months from second-line treatment initiation. Median TNT-D were respectively 9.3 (9.7-12.1) months and 6.9 (5.9-7.7) months. CONCLUSION This study highlights the limited survival of aRCC patients These results provide a valuable baseline and highlight the need for innovation, such as immune checkpoint inhibitor-based combinations that have recently became first-line standard of care.

Abstract
INTRODUCTION The incidence of small renal tumors (≤4cm) is on the rise. The gold standard treatment is partial nephrectomy (PN) but focal therapy can be a good alternative. We evaluated oncological control after treatment of T1a renal tumors by microwave ablation (MWA) compared to PN. METHODS This is a retrospective, single-center study of all patients treated for TNM stage T1a renal tumors by either PN or MWA between 2010 and 2020. A propensity score was calculated and patients were matched 2:1 to compare recurrence-free survival, metastasis-free survival and overall survival between groups. We also compared postoperative complications using the Clavien-Dindo classification. RESULTS After matching and propensity score, the two groups (41 MWA and 82 PN) were comparable. The median follow-up was 23 months (interquartiles, 9-48 months). Recurrence-free survival was higher in the PN group compared to MWA, with a recurrence rate of 17.1% in the MWA group vs 4.9% in the PN group (P=0.003). MWA treatment was a risk factor for tumor recurrence (P=0.002), but there was no significant difference in terms of metastasis-free survival (P=0.549) or overall survival (P=0.539). MWA was associated with fewer postoperative complications (P=0.0005). CONCLUSION This study shows that MWA was associated with higher risk of recurrence but similar metastasis-free survival and overall survival compared to PN. Recurrence was treated with new MWA or active surveillance. MWA may be an interesting alternative to PN for small renal tumors. LEVEL OF EVIDENCE Grade C.

Efficacy and safety of cabozantinib rechallenge in metastatic renal cell carcinoma: A retrospective multicentric study. Eur J Cancer 2023; 193:113292.

Abstract
BACKGROUND Despite metastatic renal cell carcinoma (mRCC) expanded treatment options, disease progression ultimately occurs for most patients. Rechallenge may be a compelling strategy in a refractory setting. Cabozantinib is the standard of care in first and later lines of therapy, but its activity in rechallenge is unknown. METHODS This retrospective study assessed the efficacy and safety of cabozantinib rechallenge, as defined by a second exposure after an interval of ≥3 months without treatment or ≥1 other treatment line, in patients with mRCC. The primary endpoint was median progression-free survival (PFS) at rechallenge. Secondary endpoints included overall survival, objective response rate, and safety at rechallenge. RESULTS We included 51 mRCC patients who received cabozantinib in a rechallenge setting between 2017 and 2022. Median age at diagnosis was 54 years, 78% were male, 90% had clear cell mRCC, and 92% had prior nephrectomy. 15 patients (29%) were rechallenged after a pause in treatment, whereas 36 (70.6%) had ≥1 other treatment lines between first cabozantinib exposure (CABO-1) and rechallenge (CABO-2). Median PFS was 15.1 months (mo, 95% Confidence interval 11.2-22.1) at CABO-1 and 14.4mo (95%CI 9.8-NR) at CABO-2. Median overall survival was 67.6mo for CABO-1 (95% CI 52.2-NR) and 27.4mo for CABO-2 (95%CI 17.2-NR); objective response rate was 70.6% for CABO-1 and 60% for CABO-2. CABO-2 PFS was higher for patients with CABO-1 PFS > 12 months, and for those who discontinued CABO-1 because of toxicity, without statistical significance. There were no unexpected adverse events. CONCLUSIONS Cabozantinib rechallenge is a feasible treatment option with potential clinical benefit for mRCC patients.

Detection Rate and Spectrum of Pathogenic Variations in a Cohort of 83 Patients with Suspected Hereditary Risk of Kidney Cancer. Genes (Basel) 2023; 14:1991. [PMID: 38002934 PMCID: PMC10671640 DOI: 10.3390/genes14111991] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/13/2023] [Revised: 10/20/2023] [Accepted: 10/22/2023] [Indexed: 11/26/2023] Open
Abstract
Hereditary predisposition to cancer affects about 3-5% of renal cancers. Testing criteria have been proposed in France for genetic testing of non-syndromic renal cancer. Our study explores the detection rates associated with our testing criteria. Using a comprehensive gene panel including 8 genes related to renal cancer and 50 genes related to hereditary predisposition to other cancers, we evaluated the detection rate of pathogenic variants in a cohort of 83 patients with suspected renal cancer predisposition. The detection rate was 7.2% for the renal cancer genes, which was 2.41-fold higher than the estimated 3% proportion of unselected kidney cases with inherited risk. Pathogenic variants in renal cancer genes were observed in 44.5% of syndromic cases, and in 2.7% of non-syndromic cases. Incidental findings were observed in CHEK2, MSH2, MUTYH and WRN. CHEK2 was associated with renal cancer (OR at 7.14; 95% CI 1.74-29.6; p < 0.003) in our study in comparison to the gnomAD control population. The detection rate in renal cancer genes was low in non-syndromic cases. Additional causal mechanisms are probably involved, and further research is required to find them. A study of the management of renal cancer risk for CHEK2 pathogenic variant carriers is needed.

Abstract
INTRODUCTION AND IMPORTANCE The thromboembolic complication of kidney's tumor is rare, and they can be the reason for the discovery of those tumor. Also the collision kidney tumor, such as a simultaneous occurrence of different histological types of adjacent neoplasms in the same organ is rare. CASE PRESENTATION We report a patient diagnosed with a kidney tumor discovered in the context of an etiological assessment of thrombosis, presenting with pulmonary embolism and deep vein thrombosis of the lower limb. This tumor treated by a cytoreductive nephrectomy. The histologic diagnosis of PRCC (Papillary Renal Cell Carcinoma) associated with a chromophobe cell carcinoma and sarcomatoid component was rendered. CLINICAL DISCUSSION The development of the tumor process and its progression to the metastatic stage is largely favored by the hypercoagulable state, and the cancer itself promotes the appearance of thrombo-enmbolic phenomena due to this phenomenon. Two major studies recommend that immediate cytoreductive nephrectomy should be offered to metastatic patients with a good general condition. CONCLUSION A renal tumor collision is rare, whereas the risk factors for a renal tumor collision are the same as a renal tumor without collision, just as the management of a metastatic renal tumor is the same. Understanding the thromboembolic physiopathology in the case of kidney cancer has made it possible to optimize management.

Abstract
OBJECTIVES The aim of our study was to evaluate the morbidity and mortality, as well as the oncogical results of patients who had undergone surgical procedure for a kidney cancer with thrombus extension into the inferior vena cava. MATERIALS AND METHODS Between January 2004 and April 2020, 57 patients were operated by enlarged nephrectomy with thrombectomy for kidney cancer with thrombus extension in the inferior vena cava. Twelve patients (21%) with the use of cardiopulmonary bypass because the thrombus was upper than the sus-hepatic veins. Twenty-three patients (40.4%) were metastatic at diagnosis. RESULTS Perioperative mortality was 10.5%, without difference according to surgical technique. Morbidity during hospitalization was 58%, without difference according to surgical technique. Median follow-up was 40.8±40.1months. Overall survival at 2 and 5years was 60% and 28%, respectively. At 5years, the principal prognostic factor was the metastatic status at diagnosis, in multivariate analysis (OR: 0.15, P=0.03). Progression free survival mean was 28.2±40.2months. Progression free survival at 2 and 5years was 28% and 18%, respectively. All the patients who were metastatic at diagnosis had a recurrence in an average time of 5.7months (median of 3months). Thirteen percent of patients can be considered cured at the end of the study. CONCLUSION Morbidity and mortality of this surgery remain important. The metastatic status at diagnosis has appeared to be the principal prognostic factor on the survival of these patients. LEVEL OF EVIDENCE Level 4: retrospective study.

Bull Cancer 2023; 110:160-167.

Abstract
INTRODUCTION 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. MATERIALS AND METHODS 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). RESULTS 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). CONCLUSION 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.

Can Pre-Operative Neutrophil-to-Lymphocyte Ratio (NLR) Help Predict Non-Metastatic Renal Carcinoma Recurrence after Nephrectomy? (UroCCR-61 Study). Cancers (Basel) 2022; 14:cancers14225692. [PMID: 36428784 PMCID: PMC9688470 DOI: 10.3390/cancers14225692] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2022] [Revised: 11/15/2022] [Accepted: 11/17/2022] [Indexed: 11/22/2022] Open
Abstract
Recent studies suggested that the neutrophil-to-lymphocyte ratio (NLR) could play a key role in tumor initiation, progression and response to treatments. The main objective was to assess the prognostic value of the pre-operative NLR on recurrence-free survival (RFS) in patients with non-hereditary localized renal cell carcinoma. From the UroCCR database (NCT03293563), factors influencing the disease recurrence of consecutive patients who underwent nephrectomy for cT1-T4 N0M0 were analyzed using multi-variate cox regression and log-rank methods. We included 786 patients, among which 135 (17.2%) experienced a recurrence at a median time of 23.7 [8.5-48.6] months. RFS for patients with a pre-operative NLR of <2.7 was 94% and 88% at 3 and 5 years, respectively, versus 76% and 63% for patients with a NLR of ≥2.7 (p < 0.001, log-rank test). To predict the risk of post-operative recurrence, the NLR was combined with the UCLA integrated staging system (UISS), and we defined four groups of the UroCCR-61 predictive model. The RFS rates at 3 and 5 years were 100% and 97% in the very-low-risk group, 93% and 86% in the low-risk group, 78% and 68% in the intermediate-risk group and 63% and 46% in the high-risk group (p < 0.0001). The pre-operative NLR seems to be an inexpensive and easily accessible prognostic bio-marker for non-metastatic RCCs.

Comparison of open and robotic-assisted partial nephrectomy approaches using multicentric data (UroCCR-47 study). Sci Rep 2022; 12:18981. [PMID: 36347900 PMCID: PMC9643517 DOI: 10.1038/s41598-022-22912-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2022] [Accepted: 10/20/2022] [Indexed: 11/09/2022] Open
Abstract
We compared the outcomes of robotic-assisted partial nephrectomy (RPN) and open partial nephrectomy (OPN) using contemporary data to respond to unmet clinical needs. Data from patients included in the registry who underwent partial nephrectomy between January 01, 2014 and June 30, 2017 within 20 centres of the French Network for Research on Kidney Cancer UroCCR were collected (NCT03293563). Statistical methods included adjusted multivariable analyses. Rates of peri- and post-operative transfusion, and of surgical revision, were lower in the RPN (n = 1434) than the OPN (n = 571) group (2.9% vs. 6.0%, p = 0.0012; 3.8% vs. 11.5%, p < 0.0001; 2.4% vs. 6.7%, p < 0.0001, respectively). In multivariable analyses, RPN was independently associated with fewer early post-operative complications than OPN (overall: odds-ratio [95% confidence interval, CI] = 0.48 [0.35-0.66]; severe: 0.29 [0.16-0.54], p < 0.0001 for both) and shorter hospital stays (34% [30%; 37%], p < 0.0001). RPN was also a significantly associated with a decresedrisk of post-operative acute renal failure, and new-onset chronic kidney disease at 3 and 12 months post-surgery. There were no between-group differences in oncological outcomes. In comparison with OPN, RPN was associated with improved peri- and post-operative morbidity, better functional outcomes, and shorter hospital stays. Our results support the use of RPN, even for large and complex tumours.

Abstract
Robot Assisted Partial Nephrectomy (RAPN) is a standard of care for localized renal tumors. It allows a good carcinological control while limiting complications. Despite numerous benefits, the economic sustainability of robotic assistance remains a challenge in the French health care system. The introduction in our institution of two perioperative nurse-coordinated protocols for patients undergoing RAPN (Enhanced Recovery After Surgery: NP-RAAC in 2015 and Outpatient: Ambu-Rein in 2016) is associated with a shortening of the average length of hospital stay, thus reducing the cost of robotic assisted procedures. With the aim of improving efficiency of nursing support within these protocols, we have introduced digitalized nursing coordination by developing a urological perioperative application: UroConnect®. This device is offered to patients by the coordinating nurses during a preoperative visit. It provides information on the pathology and its surgical management. Self-completed questionnaires sent at key moments collect data from the first month after surgery and detect patients presenting difficulties or complications, allowing the nurses to respond with appropriate care. The application allows a secure discharge, a personalised follow-up and an increase in the patient's autonomy and compliance with care.

Abstract
BACKGROUND The prognostic impact of renal cell carcinoma (RCC) morphotype remains unclear in patients who undergo partial nephrectomy (PN). Our objective was to determine the risk factors for recurrence after PN, including RCC morphotype. METHODS Patients with RCC who had undergone PN were extracted from the prospective, national French database, UroCCR. Patients with genetic predisposition, bilateral or multiple tumours, and those who had undergone secondary totalization were excluded. Primary endpoint was 5-year, recurrence-free survival (RFS), and secondary endpoint was overall survival (OS). Risk factors for recurrence were assessed by multivariable Cox regression analysis. RESULTS Overall, 2,767 patients were included (70% male; median age: 61 years [interquartile range (IQR) 51-69]). Most (71.5%) of the PN procedures were robot-assisted. Overall, 2,573 (93.0%) patients were recurrence free, and 74 died (2.7%). Five-year RFS was 84.9% (IQR 82.4-87.4). A significant difference in RFS was observed between RCC morphotypes (p < 0.001). Surgical margins (hazard ratio [HR] = 2.0 [95% confidence interval (CI): 1.3-3.2], p < 0.01), pT stage >1 (HR = 2.6 [95% CI: 1.8-3.7], p < 0.01]) and Fuhrmann grade >2 (HR = 1.9 [95% CI: 1.4-2.6], p < 0.001) were risk factors for recurrence, whereas chromophobe subtype was a protective factor (HR = 0.08 [95% CI: 0.01-0.6], p = 0.02). Five-year OS was 94.0% [92.4-95.7], and there were no significant differences between RCC subgroups (p = 0.06). The main study limitation was its design (multicentre national database), which may be responsible for declarative bias. CONCLUSIONS Chromophobe morphotype was significantly associated with better RFS in RCC patients who underwent PN. Conversely, pT stage, Fuhrman group and positive surgical margins were risk factors for recurrence.

Abstract
To improve the quality of computed tomography (CT) images and provide help for benign and malignant diagnosis of renal parenchymal tumors, the independent component analysis (ICA) denoising algorithm was used. An improved ICA X-ray CT (X-CT) medical image denoising algorithm was proposed. ICA provided a higher signal-to-noise ratio for CT image denoising. Forty patients with renal tumor were selected as the observation group. The CT image performance of patients was evaluated by the denoising algorithm and compared with the wavelet transform algorithm, and the peak signal-to-noise ratio of the proposed algorithm was analyzed and compared. The results showed that among the 40 patients with renal tumors, 12 were renal clear cell carcinoma cases and 28 were cystic renal carcinoma cases. The accuracy of the enhanced CT image was 93.8%, and that of the CT image using the denoising algorithm was 96.3%; the difference between the two was significant (P < 0.05). The peak signal-to-noise ratio (PSNR) of the algorithm proposed was higher than the PSNR values of CT and noisy images. The PSNR of the proposed algorithm was significantly higher than that of mean filtering. The root mean square error (RMSE) algorithm of the proposed algorithm was significantly lower than that of the mean algorithm in image data processing (P < 0.05), which showed the superiority of the proposed algorithm. Enhanced CT can be staged significantly. In conclusion, the algorithm had a significant effect on the edge contour of detailed features, and the accuracy of CT images based on intelligent calculation was significantly higher than that of conventional CT images for benign and malignant renal parenchyma tumors, which was worth promoting in clinical diagnosis.

Abstract
BACKGROUND Ablative therapies (AT) are increasingly being offered to patients with kidney tumors. In cases of failure or local relapse, salvage surgery may be required. Such procedures often require an open approach, are difficult and have received little attention in the literature. We aim to evaluate the feasibility of salvage robot-assisted partial nephrectomy (sRAPN) after AT. METHODS We conducted a monocentric retrospective study of all patients who benefited from sRAPN. Clinical data were collected prospectively after written consent in the French UroCCR database. RESULTS Between 2013 and 2020, 724 RAPN were performed in our center; of these, 11 patients underwent salvage RAPN and four (36.4%) had an imperative indication for a solitary kidney. The median patient age was 54 (49-72) years, median preoperative glomerular filtration rate (GFR) was 65.5 (42.9-88.4) mL/min/1.73 m2, and median tumor diameter was 34 (16-38) mm. Extensive perinephric fibrosis was present in 90.9% of cases. Postoperative complications occurred in 36.4% of patients, including major complications in 18.2%. The median GFR at three months (56.8 [45.9-63.9] mL/min/1.73 m2) and at last follow-up (52.1 [45.85-68.3] mL/min/1.73 m2) were not significantly different to the preoperative GFR (P=0.51 and P=0.65, respectively). During follow-up (median 12 months), three patients (all with Von Hippel Lindau disease) developed a recurrence, but none were on the sRAPN site. CONCLUSIONS Our series of sRAPN following AT failure confirms that such surgery is feasible with good functional and oncological results. However, these surgeries remain difficult, are associated with significant complication rate and should be performed in expert centers.

Safety and Oncologic Outcomes of Percutaneous Cryoablation of Renal Cell Carcinoma Recurrences in the Ipsilateral Kidney Following Partial Nephrectomy. Cardiovasc Intervent Radiol 2022; 45:656-664. [PMID: 35274173 DOI: 10.1007/s00270-022-03079-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/18/2021] [Accepted: 12/25/2021] [Indexed: 11/02/2022]
Abstract
PURPOSE To retrospectively investigate the safety and oncological outcomes of cryoablation performed on residual/recurring renal cell carcinoma (RCC) in the ipsilateral kidney following partial nephrectomy (PN). MATERIALS AND METHODS Data dealing with patients', RCC, procedure (including the length of the hospital stay), and follow-up (technical efficacy [TE], local tumor progression-free survival [LTPFS], disease-free survival [DFS], metastasis-free survival [MFS], cancer-specific survival (CSS), and overall survival [OS]) were retrospectively collected and analyzed. RESULTS Between January 2008 and November 2020, 21 consecutive patients (17 [81%] men; 4 [19%] women; median age 68 years; range 43-82) underwent cryoablation due to residual/recurring RCC in the PN site (15 patients) or de-novo RCC (6 patients) in the ipsilateral kidney. Median tumor size was 2.2 cm (mean 2.3 cm; range 0.8-4; interquartile range [IQR] 1.9-3). There were two (2/21; 10%) minor self-limiting hemorrhagic complications, both occurring in the group of patients with RCC in the PN site. Median hospital stay was 2 days (mean 2.1; range 1-5; IQR 2-2). TE was 100% (21/21 patients), and 10-year estimates of LTPFS, MFS and DFS were 74.1% (95% confidence intervals [CI] 56.8-96.7%), 36.4% (95% CI 14.2-93.8%), and 43.5% (95% CI 21.9-86.4%), respectively. CSS and OS were 100% at the last available follow-up (median 56 months; mean 67.4; range: 12-147; IQR:34-95). CONCLUSION Cryoablation in patients with residual/recurring RCC following PN is safe and results in high 10-year estimates of LTPFS.

Disease Progression in Older Patients With Renal Tumor Assigned to an Active Surveillance Protocol. Clin Genitourin Cancer 2021; 20:e53-e60. [PMID: 34815184 DOI: 10.1016/j.clgc.2021.09.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/10/2021] [Revised: 09/20/2021] [Accepted: 09/21/2021] [Indexed: 12/24/2022]
Abstract
BACKGROUND Active surveillance (AS) is a validated option for the treatment of small renal masses (SMRs), especially in older patients. This study investigates the oncologic outcomes and competitive mortality of older patients prospectively assigned to AS. METHODS We conducted a monocentric study on patients ≥75 years treated between 2011 and 2016 for a SMR. Treatment modalities, biopsy data, survivals (overall, specific, cancer progression) and delayed interventions were analyzed. RESULTS Overall, 106 patients (median age 80.5 years) were included, of which 41 were managed by AS during a follow-up of 3.4 years [0-7.1]. Seven patients (17%) had a primary biopsy with 3 confirmed renal cell carcinomas. Fourteen patients (34.1%) presented with progression (29.2% local; 4.9% metastatic), 8 (19.5%) requiring delayed interventions (75% ablative therapy and 25% radical nephrectomy). Overall survival (OS) was 68.3% and cancer specific survival was 95.1% during the study period. Competitive mortality was higher (84.6%) than cancer specific mortality (15.4%), P = .001. CONCLUSION The growth rate of progression including 4.9% metastatic progression underlines the value of AS compared to simple watchful surveillance in the treatment of SMRs in older patients. Of note, the higher competitive mortality confirm that AS should be preferred to active intervention at the beginning of the management.
