*All participants had completed their radiation therapy at study entry. Only three patients treated with chemotherapy were still on treatment at study entry. For hormone therapy, 74% of the 86 patients treated were still on treatment at study entry and this percentage was not significantly different between groups (63.2% for StanCBT-I vs. 78.2% for StepCBT-I), χ2 (1) = 1.67, p = .20.

These patients were included because their cancers were stages IVA and had spread to lymph nodes only.
