恶性瘤

Primary operation cases of parotid pleomorphic adenoma have more proliferative activity of Ki-67 than nonrecurrent group, less than group of low grade malignant parotid gland tumors. Partial parotidectomy is still suitable for primary operation cases of parotid pleomorphic adenoma.

腮腺多形性腺瘤手术复发前者Ki-67增殖活性高于未复发者，但与低度恶性腮腺肿瘤比较，其增殖活性明显不同，因此手术方式仍可选择腮腺部分切除术，但应结合其组织病理学和增殖活跃的特点，加强术后随访。

There were no false positive reports among the 220 (40.1%) biopsies interpreted as benign lesions in paraffin sections. Among 329 (59.9%) malignant biopsies on paraffin sections, 3 cases were interpreted as benign lesions on frozen sections. Three false negatives included 2 ductal carcinoma in situ and one infiltrating ductal carcinoma associated with papillomatosis. The tumors were small and confined to the breast without any evidence of metastasis.

本研究针对五年来本院 549 例乳房病理冰冻切片及永久性石蜡病理切片诊断比较，发现在 220 例的良性乳房病变40.1%）并未发现任何假阳性的冰冻病理切片诊断，而在 329 例（ 59.9 %）恶性乳房病变中，其中有三例假阴性包含二例乳房管道原位癌及一例合并良性乳突瘤的浸润性乳癌，而这三例均属较小病变及未有腋下淋巴腺转移。

The anti-tumor effects of PDT are based on higher affinity of photosensitizer and tumor tissues.

目前PDT主要应用在实体瘤和皮肤疾病的治疗领域，在造血干细胞移植治疗血液系统恶性疾病方面的研究甚少。

Both benign and malignant endocrine neoplasms demonstrate some degree of cellular pleomorphism , so it is not easy to tell benign from malignant on histologic grounds alone.

内分泌系统的良恶性肿瘤的瘤细胞均呈现一定程度的细胞的异型性，因此，在组织学上很难区分肿瘤的良恶性。

Objective To study the clinicopathologic characteristics of diffuse myxoid malignant fibrous histiocytoma of pleura.

目的探讨胸膜弥漫性黏液性恶性纤维组织细胞瘤的临床和病理特点。

Methods Retrospective reviewed malignant fibrous histocytoma imaging characteristics and manifestations with X ray, CT and MRI, that lesions were located in right superior extremity tibia 1 case and left psoas major muscle 1 case.

回顾分析了经手术、病理证实的右胫骨上端和左侧腰大肌恶性纤维组织细胞瘤各1例的X线、CT或MRI的影像学特征和表现。

I think there are two important differential diagnoses for this case - seminoma and high grade diffuse large B cell lymphoma.

译：我认为本例有两个重要的鉴别诊断：单纯的精原细胞瘤和高度恶性的弥漫的大B细胞淋巴瘤。

But operation operation often can increase sex of source of malign cell cure to diffuse odds and the result that affects operation cure. 1954 the Cole idea that put forward to manipulate a technology without tumour [2] , it is the to decrease or prevent cancer cell desquamation in showing the operation in malignant tumor is operated, cultivate and sow what come loose and adopt a series of measure, its purpose is to prevent path of blood of cancer cell edge, lymphatic path to diffuse, 2 it is to prevent cancer cell to cultivate.

但手术操作往往会增加恶性细胞医源性扩散几率而影响手术治疗的效果。1954年Cole等提出了无瘤操作技术的概念[2]，它是指在恶性肿瘤的手术操作中为减少或防止癌细胞的脱落、种植和播散而采取的一系列办法，其目的一是防止癌细胞沿血道、淋巴道扩散，二是防止癌细胞种植。
