In the 25 patients with specimens suggesting fibroadenoma, excisional biopsy confirmed the diagnosis in 23 patients but revealed phyllodes tumor in two patients, yielding a negative predictive value of 93%.

建议为纤维性瘤的25名患者中，在23个患者中进行切除的组织切片检查而确认诊断，但是其中二名患者为叶状瘤，得到93%的阴性预测值。

From August 21, 1998, to December 14, 2001, 57 core needle biopsy specimens suggested the possibility of phyllodes tumor. Median patient age was 42 years (range, 16-77 years), and median lesion diameter was 1.1 cm (range, 0.6-3.6 cm). Of the 57 specimens, 25 had pathological findings favoring a diagnosis of fibroadenoma, 23 favored phyllodes tumor, and nine were equivocal.

从1998年8月21日至2001年12月14日，共有57个粗针切片检查样本显示出叶状瘤的可能性，这些患者年龄中位数为42岁（范围16-77 岁），病灶直径中位数为1.1 厘米（范围 0.6-3.6 厘米），在57 个样本中，25个的病理研究结果建议为纤维性瘤，23个为叶状瘤，其余的九个诊断的意义不明确。

For the 23 core biopsies suggesting phyllodes tumor, excisional biopsy confirmed the diagnosis in 19 but revealed fibroadenoma in four patients, for a positive predictive value of 83%. Final pathological analysis of the equivocal core biopsies diagnosed fibroadenoma in five patients and phyllodes tumor in four patients. Final analysis determined that none of the lesions were malignant.

23个核心组织切片检查建议为叶状瘤的患者，进行切除的组织切片检查后，确认了19名患者的检验结果，但是有4人为纤维性瘤，因此得到83%的阳性预测值，有歧异的粗针检查进行最后的病理分析后，发现五名患者为纤维性瘤，而四名患者为叶状瘤，最后的分析测定这些肿瘤都不是恶性的。

Sept. 11, 2003 Core needle biopsy helps differentiate phyllodes tumor from fibroadenoma, according to the results of a query of a radiology database published in the September issue of the Archives of Surgery . The authors suggest that this technique can signficantly reduce the need for surgery of fibroepithelial lesions.

Sept。 11， 2003-根据一篇发表於9月号Archives of Surgery的研究结果显示，粗针切片检查有助於自纤维性瘤区分出叶状瘤，作者建议，这种技术也可以明显地减少进行纤维上皮之病灶手术的需要。

Patients developed head cervical lymph node swelling. The lymph node biopsy revealed a background of reactive lymphadenopathy and necrosis in some cases and apoptosis, nuclear debris in all cases, loss of lymph node structure, proliferation of lymphocytes and various types histiocytes with phagocytosis, no infiltration of neutrophils. Three histological types: proliferative, necrotizing and xanthomatous were classified.

形态特征为在活跃的反应性增生淋巴结病变的背景下，出现不同程度的凝固性坏死，淋巴细胞凋亡及核碎片几乎见于所有病例，伴有多种形态的组织细胞增生，吞噬现象明显，无中性杜白细胞浸润，组织学上可分为3型：增生型，坏死型及黄色瘤样型。

METHODS: 40 cases were classified stage IV with lumen obstruction after they failed all other treatment regimens. PDT was performed witn 630nm light delivered through cylinder diffusing tip quartz fibers passed through the biopsy channel of a flexible endoscope 48h after intravenous injection of the photosensitizer photofrin. PDT endoscopy was repeated and necrotic tissue was mechanically removed and, if necessary, that site or other new sites were treated after 48 hours. Two days after this another endoscopy was performed and the necrotic tissue was mechanically removed. Endoscopy was repeated one month after PDT and periodically thereafter as needed to re-treat symptomatic residual tumor.

40例肿瘤患者均属于IV期，所有患者都经过化疗、放疗或其他方法治疗无法解除腔道梗阻或不完全梗阻，部分完全梗阻患者结合其他治疗手段解除梗阻，光敏剂为photofrin，按2mg/kg体重静脉滴注，48小时后经内镜导入光导纤维给以630nm（DIOMED半导体激光治疗机）的激光照射，2天后经内镜清除坏死组织并对原有病灶和新发现病灶给以复照，之后根据具体情况给患者的病灶部位清除坏死组织。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
