|Patients With Newly Diagnosed Small Renal Masses(<4cm)|
Since most renal cell carcinomas (RCC's) that are now detected by imaging as small renal masses, grow slowly and remain asymptomatic for years, we hypothesize that:
- Small RCC's that are destined to metastasize do so early or after they reach a larger size
- Delayed surgical treatment of asymptomatic, incidentally detected, small RCC's WILL NOT have a significant impact on overall survival
- The majority of small RCC's MAY NOT need to be treated.
- RCC's that are destined to progress can be identified by abnormal perfusion patterns on imaging and by their cellular and genomic characteristics on needle biopsy.
|Study Type :||Observational|
|Estimated Enrollment :||170 participants|
|Official Title:||Role of Active Surveillance and Identification of Prognostic Factors for Progression in Early Stage Renal Cell Carcinoma|
|Study Start Date :||August 2004|
|Estimated Primary Completion Date :||December 2020|
|Estimated Study Completion Date :||January 2024|
- Tumour progression: [ Time Frame: 4 times year 1, 2 times year 2 and 3, yearly thereafter ]i) calculated tumour volume doubles (100% increase) within any one-year period, and/or ii) the maximum tumour diameter reaches 4 cm., and/or iii) patients develop symptoms considered to be possibly due to their renal tumour and/or iv) patients develop metastases
- Time to Tumour Progression [ Time Frame: 4 times year 1, 2 times year 2 and 3, yearly thereafter ]Time to tumour progression will be measured from the date of diagnosis to the date of progression or, if progression has not occurred, until the date of last follow-up.
- Growth rate [ Time Frame: 4 times year 1, 2 times year 2 and 3, yearly thereafter ]Defined by volume (cm3 ) measured over time (years). Tumour bi-dimensional diameter will be recorded and reported to allow comparison with the literature to date. Tumour volume will be calculated from follow-up images using the formula for ellipsoid volume: 0.5326 x X x Y x Z.
