Abstract

Hypothesis / aims of study
Kidney cancer accounted for 4% of total cancer cases diagnosed in the UK between 2016 and 2018 making it the 7th most common cancer. The management of renal tumours varies between Surgical and non-surgical. The surgical management includes radical and partial nephrectomy that can be done with different techniques including open, Laparoscopic and Robotic. The non-surgical management include Active surveillance, watchful waiting or Tumour ablation by cryoablation, Radiofrequency and microwave ablation. 

The aim of the study to ensure the adherence to the guidelines in terms of active surveillance and watchful waiting.
Study design, materials and methods
Data collected from a cohort of 19 Renal tumour patients under active surveillance or watchful waiting. Tumour size, Annual tumour growth rate, and histology were analysed along with ASA score and co-morbidities of all patients.
Results
Results Showed that average initial tumour size at the start of surveillance was 28mm. In addition, an average surveillance length of 2.4473 years showed an average annual tumour growth of 1.8125mm/year. The results led to re-visiting the scans of 4 patients out of 19 at the MDT to re-discuss as their tumour size either exceeded 30mm or the tumour annual growth rate was more than 5mm/year
Interpretation of results
Active survillance as an option for renal tumors, Is not a final call and change of management plans remains an option according to regular scans outcome. Management change to ablation option or surgical option remains an option that requires discussion with the patient whenever any of the criteria of active survillance is no longer applicable to the tumor
Concluding message
Patients with renal tumours under active surveillance and watchful waiting requires annual scanning to ensure close monitoring of tumour size and annual growth rate. Ablation of renal tumours should be considered in surgically unfit patients whose renal tumours exceed 30mm or with annual growth rate more than 5mm/year when applicable
