Synchronous Head and Neck Squamous Cell Carcinoma and Hematologic Malignancies.

Synchronous occurrence of solid tumors and hematological malignancy is a rare condition. There is no standard management or therapy for this complicated situation. The authors systematically reviewed articles searched using online databases. The patients are predominantly male, and the average age is similar to each malignancy. According to these studies, most patients are treated in order of aggressiveness. However, when a patient has multiple primary malignancies, all of which are aggressive, the treatment decision is challenging. Due to the limited number of cases, it is hard to have a firm conclusion about an optimal treatment policy. It appears that poor outcomes are mostly related to less adequate therapy. Because the condition is complicated in such cases and there is no standardized treatment, patients should be treated on an individual basis with treatments customized to a given patient's particular circumstances. In addition, multidisciplinary communication and cooperation are crucial in the management of these patients. More in-depth research is still needed to reach a more conclusive treatment strategy and predictable outcomes.
