Percutaneous cryoablation of small kidney tumours under magnetic resonance imaging guidance: Medium-term follow-up

Abstract

In this small group of patients, percutaneous renal tumour cryoablation under MRI guidance was efficient and carried no morbidity. Hospital stay was remarkably shorter than that of surgically treated patients. At medium-term follow-up, no recurrence has been identified, but long-term follow-up is required.

The correlation between size of renal cell carcinoma and its histopathological characteristics: a single center study of 1867 renal cell carcinoma cases

“…Presently, RN or NSS was considered to be the standard treatment for clinically localized RCC; but it was not always the optimal choice in some special circumstances, especially in patients with worse medical conditions and performance status. Active surveillance [3], cryotherapy [4], and radio frequency ablation [5] had proven to be effective treatment options in selected patients. Therefore, doctors must balance the risk and the benefit, and individualize the treatment option.…”

“…With the widespread use of advanced imaging techniques, such as ultrasonography, computed tomography (CT) and magnetic resonance imaging (MRI), the detection rate of renal solid tumours has grown substantially, and an increasing number of smaller renal masses have been detected incidentally [1,2]. At the same time, the treatment options for renal cell carcinoma (RCC) have become more abundant, such as active surveillance [3], cryotherapy [4], and radio frequency ablation [5]; although nephron sparing surgery (NSS) and radical nephrectomy (RN) are still the standard treatment for localized RCC. Treatment should be individualized and based on a combination of patient and tumour characteristics.…”

Follow-up after radiological intervention in oncology: ECIO-ESOI evidence and consensus-based recommendations for clinical practice

“…Quantitatively, an enhancement is considered significant on MRI if it exceeds 15% on the dynamic contrast-enhanced sequence [56]. After cryoablation, a more sustainable low T2W signal intensity rim can be observed [66]. Interruption of this rim might indicate a residual tumor.…”

Use of the contrast agent in the ultrasound diagnosis of kidney tumors

“…УЗИ позволяет исключить другие заболевания почек, наличие конкрементов, оценить расположение, структуру образований, состояние чашечно-лоханочной системы, провести измерение как самих почек и ее структур, так и выявленных образований. Под ультразвуковым контролем в режиме реального времени проводятся малоинвазивные вмешательства: получение биопсийного материала, проведение радиочастотной и криоабляции патологических очагов [36][37][38][39][51][52][53]. Стоит учитывать и развитие цитологической и гистологической диагностики, что тоже играет определенную роль в морфологическом подтверждении структуры образования.…”
