The European School of Oncology Metastatic Breast Cancer Task Force recommends sequential chemotherapy with a single agent for patients without rapid progression or life-threatening metastasis.
Neuroblastoma survivors are eight times more likely to have chronic health conditions and less likely to be married or employed with high income compared to their siblings. Late mortality, second malignant tumors, and chronic health conditions were analyzed in a study of 954 survivors diagnosed between 1970-1986.
