In the subgroup analysis, based on cancer type, HOTAIR was shown to be a significant predictor for worse prognosis for a variety of cancers, including solid cancers, such as urological cancers, head and neck neoplasms, cancers of the digestive system, and several female cancers (e.g., cervical, ovarian, and endometrial cancers), as well as the blood cancers, lymphoma and leukemia. The gene discussed is HOTAIR; the disease is cancer.
