Characteristics and survival of patients with metachronous or synchronous double primary malignancies: breast and thyroid cancer

BACKGROUND Clinical experiences suggest that breast cancer (BC) and thyroid cancer (TC) occur metachronously or synchronously in a patient more frequently than it would by chance. This study was conducted to investigate the clinicopathological characteristics and survival of these double primary malignancies. METHODS 18732 patients with first primary BC and 12877 female patients with first pr...

Synchronous double primary gastric and endometrial cancer: a case report and literature review.
