    • A cancer prognostic having particular utility in the prognosis of head and neck squamous cell cancer, in which the expression levels of either or both of Transforming Growth Factor Alpha (TGF-.alpha.) or Epidermal Growth Factor Receptor (EGFR) are assayed directly from a sample of tumor tissue. The expression level once quantitated is normalized as to standard, and the standardized expression level is compared to the prognostic threshold of about 83% of standard for TGF-.alpha. or of about 23% of standard for EGFR, or the corresponding upper threshold of the "low" tertile regardless of how calculated. Virtually all if not all patients demonstrating this low expression level survive at least five years after initial diagnosis, assuming completion of treatment with standard surgical tumor excision and radiation protocols for squamous cell head and neck cancer. Whether an individual patient's expression levels of TGF-.alpha. and EGFR fall inside or outside of this category signifies whether the patient is in a good or poor prognostic category, respectively, which in turn guides appropriate choice of therapy.
    • 在头颈部鳞状细胞癌的预后中具有特殊用途的癌症预后,其中直接从样品中检测转化生长因子α(TGF-α)或表皮生长因子受体(EGFR)中的任一者或两者的表达水平 的肿瘤组织。 定量表达水平与标准化相一致,标准化表达水平与TGF-α标准的约83%或EGFR标准的约23%的预后阈值相比较,或相应的“ 低“三分位数,无论如何计算。 几乎所有如果不是全部,即使不是全部,表明这种低表达水平的患者在初步诊断后至少五年内存活,假设用标准手术肿瘤切除术和鳞状细胞头颈部癌症的辐射方案完成治疗。 个体患者的TGF-α和EGFR表达水平是否落在此类别之内或之外,都意味着患者是否处于良好或不良预后类别,从而指导适当的治疗选择。
