When there is a tumor of the thymus gland (in 10-15% of patients with MG), it is always removed because of the risk of malignancy.

人若得了胸腺瘤（肌无力患者中有10%-15%的人会并发此病，）因为怕是恶性的，所以通常会考虑切除。

Pleomorphic adenoma is the most common gland tumor of parotid origin, accounting for 60 to 70%. This kind of tumor usually presents as a slow-growing painless mass anteroinferior to the ear. The diagnosis is based on physical examination, image studying and even fine needle aspiration biopsy. The optimal method of treatment of such tumors is local excision or paroidectomy in which the entire capsule is totally dissected off but the facial nerve is spared. Diagnosis and treatment planning are focused on preventing tumor recurrence and consequent malignant transformation.

腮腺之多形性腺瘤乃是唾液腺最常见的肿瘤，约占所有唾液腺良性肿瘤的百分之六十至七十，这类的肿瘤在临床上的表现常是耳下缓慢增生的无痛性肿块，临床上诊断的依据必须配合临床检查、电脑断层扫描、磁振造影及细针抽取切片的病理检查方可得知，其治疗方式主要是对肿瘤进行局部切除手术或腮腺的切除手术，手术中颜面神经需小心保留，但须将肿瘤的外膜部分切除乾净，诊断及治疗计画著重在预防肿瘤复发及肿瘤产生恶性转变。

Immunohistochemically, the tumor cells were strongly positive for α fetoprotein and α antitrypsin.

Our research has showed that Mcl-1 AS-ODN can partially reverse the chemoresistance of melanoma.

我们前期工作也显示Mcl-1反义寡核苷酸可部分逆转恶性黑素瘤的耐药性。

Multidrug resistance is the vital factor of ineffective treatment in malignant melanoma. Thus, one of the main goals for melanoma treatment is to reverse chemoresistance of tumor cells.

而多药耐药是其临床化疗失败的主要原因，因此，逆转肿瘤的耐药性是治疗恶性黑素瘤的重要课题。

Methods Pathological sections were reviewed among the cases pathologically diagnosed as fibroadenoma and cystosarcoma phylloides and reclassification was made according to the criteria proposed by Azzopardi and Salvadori.
