Hazard rate estimates for distant metastasis in 2204 patients undergoing QuaRT, 348 patients receiving TaRT and 273 patients given Quad. The ubiquitous bimodal distant recurrence dynamics described previously following mastectomy are present when much smaller operations are employed. Radiation of the chest wall clearly does not eliminate or even delay the first early recurrence peak. Vertical lines represent point-wise confidence interval for the model estimated hazards, according to standard asymptotic theory.
