Robot-Assisted Ultrasound for Thermal Ablative Therapy in Treating Patients With Small Kidney Masses Undergoing Surgery
Robot-Assisted Laparoscopic HIFU (High-Intensity Focused Ultrasound) for Thermal Ablative Therapy of Small Renal Mass: Corroborating With Robot-Assisted Laparoscopic Partial Nephrectomy Specimens
Descripción general del estudio

Descripción detallada
PRIMARY OBJECTIVES:
I. To evaluate the efficacy of laparoscopic high-intensity focused ultrasound (HIFU) for the treatment of localized primary renal cancer to evaluate histological accuracy in successful ablation of the small renal mass, matched with intraoperative targeting.
SECONDARY OBJECTIVES:
I. To evaluate the safety and toxicity of laparoscopic HIFU for patients with primary renal cancer.
II. To evaluate the technical success of laparoscopic HIFU ablation.
OUTLINE:
Patients undergo robot-assisted laparoscopic HIFU thermal ablative therapy during partial nephrectomy.
After completion of study treatment, patients are followed up at 2 days, 2 weeks, 1 month, 6 months, 12 months, and then annually for up to 3 years.

Descripción
Inclusion Criteria:
- Presence of an enhancing solid renal mass =< 3.0 cm on radiological examination
- Tumors with a depth of not greater than 3.0 cm from a laparoscopically accessible surface-meaning no part of the tumor should be deeper than 3.0 cm from the surface
- Patients with solitary kidneys, bilateral renal tumors, compromised renal function (baseline creatinine > 1.4)
- Subjects must have given written informed consent
- Previous chemotherapy, and/or biological therapy for cancer are permitted provided that the acoustic properties of the tumor were not affected, but the subject should have recovered from the effects of these or of any prior surgery
- Subjects must be free of any clinically significant disease other than cancer that would interfere with the study evaluations
- Absolute neutrophil count (ANC) >= 1500 mm^-3
- Platelet count >= 100,000 mm^-3
- Hemoglobin >= 10 g/dl
- Prothrombin time (PT) =< 1.5 times upper limit of laboratory normal (ULN)
- Activated partial thromboplastin time =< 1.5 times ULN
- Urea and serum creatinine < 2.5 times ULN
- Total bilirubin < 1.5 times ULN
- Aspartate aminotransferase (AST) =< 3 times ULN
- Alkaline phosphatase < 2 times ULN, unless arising from bone
Exclusion Criteria:
- < 90% solid component on screening cross-sectional imaging
- Subjects deemed unsuitable candidates and not medically optimized for partial nephrectomy
- Tumors greater than 3.0 cm at their widest point
- Subjects with tumors lying < 1 cm from sensitive structures such as the ureter, renal vessels or adjacent bowel
- Subjects on concurrent anticoagulant, or immunosuppressive medication
- Subjects on anti-cancer medication whether biologic or pharmaceutical
- Women who are pregnant or nursing (pregnancy test to be performed within 24 hours prior to HIFU treatment)
- Subjects assessed by consultant anesthetist as unsuitable for general anesthetic
- Subjects having had prior ablation therapy on the same tumor
