SYK and metastatic malignant neoplasm in the lymph nodes: The expression of Syk in tumours was correlated with patients' age, tumour size, tumour grade (well, moderately or poorly differntiated), estrogen and progesterone receptor status (positive, weak positive or negative), lymph node metastasis, vascular invasion, recurrence and clinical outcome (distant metastasis and death with a median follow up of 1.95 years).
