Table 1.

Kaplan–Meier survival curves for all groups of mice with 4T1 tumors were analyzed for significance against vehicle-treated mice, and the combination therapies were additionally analyzed against the enzyme prodrug therapy

  • NOTE: The quantification of the synergism assessment based on primary tumor growth inhibition using the Bliss independence model is summarized for percent tumor inhibition for the combination therapies. Values presented as a function of the day of treatment are a “synergism assessment factor” with positive values indicative of synergism (bold), calculated from experimental values for the individual constituents of the combination therapies, and compared with the experimentally determined values of the combination therapies (see Supplementary Data for additional information about the assessment of synergism).

  • Abbreviations: Cyc, cyclophosphamide; Rap, rapamycin; Sel, selenomethionine.

  • aLog-rank–determined P values are presented and significance is indicated (P < 0.005).
