颌骨转移癌并不常见,全部恶性肿瘤约1%出现颌骨转移,颌骨的转移癌约占颌骨恶性肿瘤的1%。一旦发现,原发灶已多属晚期或转移广泛而失去根治时机,故一般预后很差。然有的肿瘤分化较好,恶性程度较低,其中一部分颌骨病变可首先被发现,且部分患者一般情况较好,经积极治疗也可获得良好效果。现将我院经治的5例报道如下,并对有关问题进行初步讨论。 The metastases of the jaws are not common. About 1% of all malignant tumors show jaw metastasis. The metastases of the jaws account for about 1% of the jaws. Once discovered, the primary lesions are mostly late or metastasize widely and lose the opportunity to cure, so the general prognosis is poor. However, some tumors are well-differentiated and have a low degree of malignancy. Some of these jaw lesions can be found first, and some patients are generally better. Positive results can also be obtained. The following five reports of treatment in our hospital are as follows, and preliminary discussion of relevant issues.
