  1. Data are presented as n (%) or mean ± standard deviation.
  2. Abbreviations: G1 1 tumor focus, G2 2 tumor foci, G3 3 or more tumor foci, NS not significant.
  3. Age at diagnosis and primary tumor size were compared using the Kruskal-Wallis test.
  4. Group comparisons of categorical variables were performed using the chi-square test or, for small cell values, Fisher’s exact test.
