  • Data from individual studies have not been included in the table when these data have been included in a subsequent or duplicate series. Data from randomised trial shown in bold.

  • 1-a Updated series: patients from Noordijk (1988)9were included in Krol (1996),16 from Hayakawa (1992)26 in Hayakawa (1996),31 from Dosoretz (1992)36 and (1993)37 in Dosoretz (1996),38 and from King (1996)33 in Sibley (1998).21

  • 1-b Overlapping series: some patients reported by Hayakawa (1996)31 and Furuta (1996)30 were included in a series with stage I tumours reported by Morita (1997)18 and in a series of peripheral stage I tumours reported by Hayakawa (1999).22 Some patients reported in Hayakawa (1996)31 were included in a subset of elderly patients with stage I/IIA tumours reported by Furuta (1996).30 Slotman (1984)13 and (1987)17 reported patients from overlapping time periods.

  • 1-c Published data supplemented by data from authors (Nguyen-Tan, personal communication).

  • 1-d Age ranges are those of a larger group which included a proportion of patients with stage III tumours.

  • 1-e Duplicate series: Hayakawa (1996)32 reported the same results as Hayakawa (1996).31
