Studien-Informationen
Detailed Description:Surgical excision is the gold standard for the treatment for localized kidney cancer. An
organ-preserving procedure should be carried out whenever possible in order to maintain
kidney function. Partial nephrectomy can be performed through the conventional open technique
as well as through a robotic-assisted approach. Although both methods belong to the standard
care, there is still no published data from randomized controlled trials in the scientific
literature comparing them. The ROBOCOP-trial is designed as a single-center comparison of the
two surgical approaches in preparation for a phase III study. 50 patients are to be included
in the trial within a period of 15 months. The primary endpoint is feasibility of patient
recruitment. In addition, potential primary outcomes for a confirmative trial such as
perioperative complications, quality of life, inflammatory response, survival and ergonomic
aspects for the operating surgeons will be investigated.
Ein-/Ausschlusskriterien
Inclusion Criteria:- scheduled for curative elective partial nephrectomy for renal neoplasms

- ability of patient to understand the goal, consequences and alternatives of
participation in the trial
- written informed consent
Exclusion Criteria:

Studien-Rationale
Primary outcome:1. Recruitment rate (Time Frame - 15 months):
Proportion of randomized patients in relation to the eligible ones.
Secondary outcome:
1. Perioperative complications (Time Frame - throughout patient´s hospital stay, on average 6 days):
Measured with 1) the comprehensive complication index (CCI), on a scale from 0 (no complications) to 100 (death) and 2) the Clavien-Dindo classification, which consists of 7 grades (I, II, IIIa, IIIb, IVa, IVb and V), the first one indicating any deviation from the normal postoperative course, the highest grade indicating death
2. Postoperative complications (Time Frame - 90 days):
Measured with 1) the comprehensive complication index (CCI), on a scale from 0 (no complications) to 100 (death) and 2) the Clavien-Dindo classification, which consists of 7 grades (I, II, IIIa, IIIb, IVa, IVb and V), the first one indicating any deviation from the normal postoperative course, the highest grade indicating death
3. Self-reported generic health status (Time Frame - 90 days):
Patient-reported generic health status using EQ-5D-5L(EuroQol-5D-5L) questionnaire (the scale ranges from 0 to 100, with 100 representing the highest health status)
4. Self-reported quality of life assessment of cancer patients (Time Frame - 90 days):
Cancer patients will be reporting their quality of life making use of the questionnaire QLQ-C30 (Quality of Life Questionnaire C30) (range 0-100, high scores represent a better quality of life)
5. Self-reported quality of life in patients with kidney disease (Time Frame - 90 days):
Patients will assess the influence of their kidney disease on everyday activities, work status, social interactions, mental and physical health making use of KDQOL-SF (Kidney Disease Quality of Life Short Form), ranging from 0 ("worst possible health") to 10 ("best possible health")
6. Self-assessment of depression in patients ≥ 65 years old (Time Frame - 90 days):
Elderly patients (≥ 65 years old) will report their depression symptoms filling GDS (Geriatric Depression Scale) questionnaire, ranging from 0 to 30, with 0-9 as "normal", 10-19 as "mildly depressed", and 20-30 as "severely depressed".
7. Self-evaluation of cancer disease´s influence on elderly patients´ life (Time Frame - 90 days):
Elderly patients (≥ 65 years old) will evaluate the influence of their cancer disease on their life (activities of daily living, cognition, mood, nutritional status, mobility, polypharmacy and social support), on a scale ranging from 0 to 17, 17 indicating the best outcome possible on quality of life.
8. Self-assessment of comorbidity in elderly patients (Time Frame - 90 days):
Elderly patients (≥ 65 years old) will make use of SCQ (Self-Administered Comorbidity Questionnaire) to assess common comorbidities; a higher score indicates higher comorbidities (range 0-39)
9. Postoperative self-reported quality of life (Time Frame - 90 days):
Participants will evaluate their postoperative quality of life on a 0-100 scale, higher scores indicating a better quality of life and return to daily life activities.
10. Kidney function - creatinine (Time Frame - 90 days):
postoperative change in kidney function - creatinine (measured in mg/dL)
11. Kidney function - GFR (Time Frame - 90 days):
postoperative change in kidney function - glomerular filtration rate (measured in mL/min)
12. Length of hospital stay (Time Frame - throughout patient´s hospital stay, on average 6 days):
Total time of hospital stay
13. Operative time (Time Frame - Immediately after surgery):
Surgery duration
14. Inflammatory response - leucocytes (Time Frame - throughout patient´s hospital stay, on average 6 days):
postoperative course of inflammatory parameters (leucocytes, unit of measure: white cells x10^9/L)
15. Inflammatory response - C-reactive protein (Time Frame - throughout patient´s hospital stay, on average 6 days):
postoperative course of inflammatory parameters (c-reactive protein, measured in mg/L)
16. Inflammatory response (Time Frame - throughout patient´s hospital stay, on average 6 days):
postoperative course of inflammatory parameters (IL-6, TNF-α, IL-1β, VEGF, measured in ng/L)
17. Surgical ergonomics (Time Frame - Immediately after surgery):
Surgeons will be asked to evaluate localized muscle pain on a scale from 0 to 10, 10 indicating extreme discomfort
18. Surgical ergonomics (Time Frame - During surgery):
Surgeons will be asked to fill NASA TLX questionnaire (NASA Task Load Index). Range: 0-100, high scores indicate a high task load
19. Resection status (Time Frame - up to 5 days):
Rate of R0/R1 status in each arm
20. Use of analgesia (Time Frame - throughout patient´s hospital stay, on average 6 days):
Need for pain medications
21. Trifecta outcomes of partial nephrectomy (Time Frame - 90 days):
Trifecta is defined as no major complication, R0-resection status and ischemia time of less than 25 minutes
22. Blood loss (Time Frame - Immediately after surgery):
Blood loss during surgery
23. Conversion to open surgery (Time Frame - Immediately after surgery):
Rate of conversion to open surgery
24. Conversion to radical nephrectomy (Time Frame - Immediately after surgery):
Rate of conversion to radical nephrectomy
