What this study is about
Partial nephrectomy (PN) is the standard treatment for localized renal masses and should be preferred in clinical T1 (\<7 cm tumor diameter) renal tumors over radical nephrectomy (RN) whenever technically feasible. Nonetheless, indications, approaches, techniques for PN, and correct reporting of outcomes, are still a matter of great debate within the urology community.
View original scientific description
Partial nephrectomy (PN) is the standard treatment for localized renal masses and should be preferred in clinical T1 (\<7 cm tumor diameter) renal tumors over radical nephrectomy (RN) whenever technically feasible. Nonetheless, indications, approaches, techniques for PN, and correct reporting of outcomes, are still a matter of great debate within the urology community. Concurrently, case-report series suggested that alternative strategies for the treatment of localized renal tumors (ablation techniques (AT), watchful waiting (WW), active surveillance (AS)) could be feasible with acceptable oncologic outcomes in particular settings of patients with localized renal tumors. In this complex clinical scenario, the role surgeon-related and environmental factors (such as surgical experience, hospital resources, countries' social background and performance of health system) are important to address the best personalized approach in patients with renal tumors. In the light of current evidence, many unsolved questions still remain and many unmet needs must be addressed. In particular, 1) the risk-benefit trade-offs between PN and RN for anatomically complex renal localized tumors; 2) the definition of evidence-based strategies to tailor the management strategy (AT vs WW vs AS vs surgery) in different subset of patients with particular clinical conditions (i.e. old, frail, comorbid patients); and 3) the definition of evidence-based recommendations to adapt surgical approach (open vs laparoscopic vs robotic) and resection techniques to different patient-, tumor-, and surgeon-specific characteristics. To meet the challenges, to overcome the limitations of current kidney cancer literature (such as the retrospective study design, potential risk of biases, and heterogeneous follow-up of most series), and to provide high-quality evidence for future development of effective clinical practice Guidelines, we designed the international REgistry of COnservative or Radical treatment of localized kiDney tumors (i-RECORD) Project. The expected impact of the i-RECORD project is to provide robust evidence on the leading clinical and environmental factors driving selection of the management strategy in patients with kidney cancer, and the differential impact of different management strategies (including AS, WW, AT, PN and RN) on functional, perioperative and oncological outcomes, as well as quality of life assessment, at a mid-long term follow-up (5-10 years).
Interventions
PROCEDURE
Partial Nephrectomy (PN)
Conservative removal of kidney tumor. The procedure can be performed either with an open or laparoscopic or robotic approach.
PROCEDURE
Radical Nephrectomy (RN)
Surgical removal of the affected kidney. Adrenal removal can be performed according to surgeon choice and clinical characteristics of the renal tumor. The procedure can be performed either with an open or laparoscopic or robotic approach.
PROCEDURE
Ablation therapy (AT)
The procedure of tumor ablation performed with radiofrequency or cryoablation. The procedure can be performed either with a laparoscopic approach or percutaneous access.
DIAGNOSTIC_TEST
Active Surveillance (AS)
Active surveillance is defined as the initial management including the monitoring of renal tumor size by serial imaging with delayed treatment in case of progression.
Primary outcome measures
To test the effectiveness of partial nephrectomy for the treatment of localized renal tumors (T1-T2N0M0) with regards to recurrence-free survival and cardiovascular accidents and mortality in comparison to radical nephrectomy?
Time frame: Assesments of the outcome at 60 months from the surgical intervention. Time frame : 5 years
The preoperative characteristics of the patients will be specifically evaluated to calculate any heterogeneity between the two groups. In detail, anthropometric and comorbidity features, previous abdominal surgery, blood chemistry values, blood pressure, smoking habit, preoperative life expectancy, and frailty grade will be assessed. Imaging features of the tumor will be considered, including the characteristics necessary for the calculation of the PADUA, R.E.N.A.L., and Contact-Surface-Area scores. Patients with a node-positive or metastatic disease diagnosed with conventional imaging (CT scan/MRI) will be excluded. Intra-operative and post-operative outcomes will be evaluated. Histopathological features of the tumor will be assessed. Patients will be followed up with conventional imaging according to the International guidelines (ultrasound, CT, MRI). Serum creatinine, platelets and estimated glomerular function (eGFR), the onset of cardiovascular adverse events will be registered.
To test the effectiveness of robotic approach in partial nephrectomy to increase the "Trifecta" rate after nephron-sparing surgery in patients with T1-T2N0M0 renal tumors.
Time frame: Assesment of the "Trifecta" outcome will be performed at 12 months from the surgical intervention. Time frame: 1 year.
"Trifecta" rate is defined as 1) Absence of intraoperative and postoperative surgical complications; 2) absence of positive surgical margins or recurrences on tumor resection site during a 5-year follow-up; 3) Absence of clinically significant renal function loss at one year after surgery. Renal function will be evaluated using the estimated glomerular filtration rate (eGFR) in ml/min/1.73 m\^2 using the CKD-EPI Creatinine Equation (2021). A clinically significant loss will be considered if \>25% from eGFR at baseline. The "Trifecta" outcome will be evaluated one year from surgery.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
