Patients with stage I disease experienced longer intervals than those with more advanced disease. A multidisciplinary approach could help reduce anxiety and mistrust by allowing sufficient time for information digestion and procedure recovery.
A meta-analysis of five published trials found that aluminium-containing vaccines were more likely to cause redness and induration in young children and local pain in older children. However, there was no evidence of serious or long-lasting side effects.
A new study suggests that premenopausal women with ER-negative breast cancer may benefit from adjuvant chemotherapy alone or followed by goserelin, while those with ER-positive tumors show no significant difference in outcomes. The findings support the idea of ovarian suppression as a treatment alternative for some premenopausal women.
A new study published in the Journal of Clinical Oncology found that low-dose interferon therapy did not extend overall or recurrence-free survival in high-risk melanoma patients. The trial involved 674 patients and found that both groups experienced similar rates of disease recurrence and mortality.
