乳腺分叶状肿瘤诊疗及预后的探讨

为了探讨乳腺分叶状肿瘤外科治疗方法的选择,观察其影响预后的因素,对我院2001-01-2008-01收治的65例乳腺分叶状肿瘤的临床资料进行回顾性分析.65例分叶状肿瘤均经手术治疗,病理良性32例,交界性13例,恶性20例;15例肿块切除术复发8例,30例行局部扩大切除术复发3例,15例行乳房单切术复发2例,5例发现腋淋巴结肿大行乳房单切+腋淋巴结清除术,其中2例分别于术后10和18个月死于远处转移.初步研究结果提示,局部扩大切除术是治疗乳腺分叶状肿瘤的首选方案,但应保证组织学上干净的切缘,乳房单切术对恶性分叶状肿瘤没有生存优势,对局部复发的交界性或恶性肿瘤选择乳房单切术,无需行淋巴结清除.     

双侧乳腺分叶状肿瘤1例报告附文献综述

乳腺分叶状肿瘤（phyllodes tumor）是一种少见的乳腺肿瘤，占乳腺肿瘤的1％，是由排列成裂隙状双层上皮成分环绕过度生长富于细胞的间叶成分组成，分良性、交界性和恶性。双侧乳腺分叶状肿瘤更是罕见，鲜有文献报道。本院收治1例双侧乳腺分叶状肿瘤合并怀孕患者，肿瘤经第一次局部手术后短期内自切口向外迅速生长，具有特殊性，现报告如下。     

妊娠合并乳腺巨大恶性分叶状肿瘤2例报告及文献复习

目的:探讨乳腺恶性分叶状肿瘤的临床特点、治疗方法和预后。方法:回顾性分析2例妊娠合并乳腺巨大恶性分叶状肿瘤的诊治过程,并复习相关文献。结果:第1例患者经手术切除后局部复发,再次手术切除、局部放疗后随访至今,未见肿瘤复发转移;第2例患者,手术后短期内局部复发,再次手术后迅速出现双肺、胸膜转移,化疗疗效不显著,患者最终死亡。结论:乳腺恶性分叶状肿瘤的异质性显著,其诊治方法仍需要不断探索。     

乳腺分叶状肿瘤临床特点与复发危险因素

目的探讨乳腺分叶状肿瘤的临床特点、诊治方法和局部复发的危险因素。方法选取1990年1月至2016年7月间柳州市工人医院收治的48例乳腺分叶状肿瘤患者的临床病理和随访资料作回顾性分析,采用卡方检验分析各临床病理因素、手术方式与局部复发的关系,采用Logrank检验分析上述因素对无病生存率的影响。结果所有患者术后病理诊断结果中,良性乳腺分叶状肿瘤29例,交界性乳腺分叶状肿瘤11例,恶性乳腺分叶状肿瘤8例,无一例发现腋窝淋巴结转移。39例随访患者,1年、3年和5年无病生存率分别为83.8%、69.4%和66.1%,5年总生存率为93.0%。局部复发者10例,其中6例患者为肿块切除术后局部复发。患者是否采用肿块切除术与局部复发关系比较,差异有统计学意义(P=0.01)。结论外科手术是乳腺分叶状肿瘤的主要治疗方法,术式选择不当与局部复发有关,对乳腺分叶状肿瘤应选择局部广泛切除、乳房切除或乳房重建术,不宜采用肿块切除术,不必常规行腋淋巴结清扫术。     

61例乳腺叶状肿瘤诊疗分析

目的探讨乳腺叶状肿瘤的临床诊断、病理以及治疗和预后的关系。方法回顾分析1973年4月至2005年2月收治的61例经病理证实为乳腺分叶状肿瘤患者的临床资料。结果61例患者平均年龄43岁,按WHO分类标准,其中36例为良性,19例为交界性,6例为恶性;34例行局部扩大切除术,18例行单纯乳房切除术,3例行单纯切除+植皮术,6例行改良根治术(1例发现淋巴结转移)。随访52例,平均随访92个月(16~378个月),共13例局部复发和转移,死亡4例。结论局部扩大切除或单纯乳房切除术是治疗乳腺分叶状肿瘤的首选治疗方法,但术前检查证实同侧腋窝淋巴结肿大的患者,考虑行改良根治术。复发治疗以手术为主,需足够的手术范围,以根治为目的。     

46例乳腺分叶状肿瘤临床病理特点及误诊分析

目的探讨乳腺分叶状肿瘤的临床病理特点及误诊原因。方法对46例经病理复诊明确诊断的乳腺分叶状肿瘤病例进行回顾性分析,并用免疫组化法检测AE1／AE3、VIM、平滑肌肌动蛋白（Act）和Ki-67表达。结果46例乳腺分叶状肿瘤术前临床诊断相符者24例,其余术前诊断分别为：乳腺纤维腺瘤15例,乳腺增生或混合性囊肿4例,乳腺癌或疑似乳腺癌3例。术前临床诊断误诊率为47．83％（22／46）。术中冰冻病理诊断为乳腺分叶状肿瘤40例,漏诊率为13．04％（6／46）。术后石蜡切片病理诊断：46例乳腺分叶状肿瘤中良性35例,交界性7例,恶性4例。免疫组化表达结果：VIM表达均为阳性,表达在肿瘤问质细胞;Act在部分病例（36．96％,17／46）表达于间质细胞;AEl／AE3均无间质细胞表达（用于排除梭形细胞癌）;Ki-67平均阳性细胞指数在良性、交界性和恶性中分别为13％、28％和69％,Ki-67表达在三者之间差异有统计学意义（P〈0．05）。结论乳腺分叶状肿瘤存在较高的临床误诊率和冰冻病理漏诊率,而其治疗方式的选择与病理分型密切相关;免疫组化对判断其良、恶性有重要意义;肿瘤的及时确诊和手术方式选择是决定治疗成功的关键。

Surgical treatment of phyllodes tumors of the breast: retrospective review of 172 cases

BACKGROUND AND OBJECTIVES: Phyllodes tumors (PTs) are uncommon biphasic breast tumors that usually occur in adult females. They are composed of a benign epithelial component and a cellular, spindle cell stroma forming a leaf-like structure. No one morphologic finding is reliable in predicting the clinical behavior of the tumor. The purpose of this study was to explore the clinicopathologic factors associated with outcome and metastasis. METHODS: We retrospectively reviewed the records of 172 patients seen at Mackay Memorial Hospital from January 1985 to December 2003. Clinical data analyzed included age, presenting symptoms and signs, tumor size, location, type of surgery, time to recurrence, and metastasis. The clinicopathologic factors associated with outcome and metastasis were analyzed statistically using the chi-square test with Yate correction. RESULTS: The mean follow-up was 71 months (range 7-237). The mean age was 37 years (range 11-73). The majority of tumors were found in the upper outer quadrant (46.0%), with an equal propensity to occur in either breast (48.8% vs. 50.0%). The pathologic diagnoses included 131 benign, 12 borderline, and 29 malignant lesions. Nineteen patients (11%) had a recurrence and three (1.7%) had metastases. The initial diagnosis of all 19 recurrent tumors were benign. Age, surgical approach, mitotic activity, and surgical margin were significantly correlated with recurrence (P = 0.029, 0.020, 0.048, and 0.00018, respectively). Stromal cellularity, stromal overgrowth, stromal atypia, mitotic activity, tumor margin, and heterologous stromal elements were significantly correlated with metastases (P = 0.032, 0.00008, 0.000002, 0.004, 0.005, and 0.046, respectively). Mammography and breast echo were not reliable for differentiating PTs from fibroadenomas (6.9% vs. 37.9% and 3.3% vs. 45%, respectively). Frozen section was of limited value (41.6%). The role of adjuvant radiotherapy and chemotherapy remains to be defined. Local excision, wide excision, or mastectomy with negative surgical margins yielded high local control rates (88.7%, 88.2%, and 100%, respectively), but local excision was associated with a relatively high percentage of positive surgical margins (18.3%). A total of 42 modified radical mastectomies were performed. The reasons for these procedures included a diagnosis of malignancy on frozen section or because the tumors were so large, they were assumed to be carcinomas. No axillary lymph node metastases were found. Fifteen patients in our series had tumors with infiltrating tumor margin, severe stromal overgrowth, atypia, and cellularity. All three patients with metastases (3/15) were in this group. Presence of metastases was significantly correlated with this group (P = 0.0000038). CONCLUSIONS: Wide excision with a clear margin may be the preferable initial therapy, even for malignant PTs. Routine axillary lymph node dissection is not recommended. Patients have tumors with infiltrating tumor margin, severe stromal overgrowth, atypia, and cellularity are at high risk for metastases.     

乳腺复发性叶状肿瘤临床病理分析

目的:探讨乳腺复发性叶状肿瘤临床及病理特征。方法:收集2011年01月至2019年12月在我院进行手术治疗的叶状肿瘤病例,并找出其中复发的病例,分析复发病例的临床及病理组织学特征。结果:叶状肿瘤137例,共有10例为复发病例,其中9例为单次复发,1例复发两次,复发病例中良性叶状肿瘤7例,交界性叶状肿瘤2例,恶性叶状肿瘤1例。所有的肿物均为局部复发,良性、交界及恶性叶状肿瘤复发率分别为5.9%、15.4%、20%。其中3例（30%）出现组织学升级,1例良性叶状肿瘤复发为交界性叶状肿瘤,1例交界性叶状肿瘤复发为恶性叶状肿瘤,1例良性叶状肿瘤第一次复发为交界性叶状肿瘤,第二次复发为恶性叶状肿瘤。免疫组化标记CD117、CD34、CD10、p53、p16在原发及复发肿瘤中表达无差异。Ki67增殖指数在复发病例中均升高,并且核分裂数也增多。结论:良性、交界性、恶性叶状肿瘤均可复发,其中恶性叶状肿瘤复发率最高,肿瘤多为局部复发,部分肿瘤复发后出现组织学升级,复发后肿瘤细胞增殖活性增强。     

乳腺叶状肿瘤的X线表现

目的探讨乳腺叶状肿瘤X线影像学特点,并与其病理对照,以提高对该病的诊断准确率。方法回顾性分析经手术病理证实有完整乳腺X线资料的乳腺叶状肿瘤50例共54个病灶,其中良性26个、交界性22个、恶性6个。结果 54个病灶中表现为伴或不伴钙化的肿块50个(92.6%),假阴性4个(7.4%)。50个肿块病变中良性23个、交界性21个、恶性6个。形状以分叶状、圆形或卵圆形最多见,分别占62.0%(31/50)、10.0%(5/50)、26.0%(13/50)。肿块边缘主要表现为清楚或部分清楚部分模糊,占80%(40/50),其余肿块呈浸润状及细小分叶状边缘,分别占18.0%(9/50)和2.0%(1/50)。肿块表现为高密度占74.0%(37/50),等密度占26.0%(13/50)。3个病灶肿块内含有钙化。边缘特征在良性与恶性肿瘤、交界性肿瘤与恶性肿瘤之间有明显差异,P_(良-恶)=0.003,P_(良-恶)=0.044。结论乳腺叶状肿瘤主要X线表现为分叶状或圆形、卵圆形的高密度肿块,钙化少见;边缘特征可在一定程度上提示良恶性叶状肿瘤的区别。     

乳腺叶状肿瘤17例诊治分析

[目的]总结乳腺叶状肿瘤的诊治情况。[方法]回顾分析17例经病理证实乳腺叶状肿瘤的临床资料。[结果]17例中良性11例,交界性3例,恶性3例。行乳腺肿瘤局部切除3例,乳腺肿瘤扩大切除7例,乳房切除术4例,乳房改良根治术3例,3例乳腺肿瘤术后出现复发。[结论]乳腺叶状肿瘤术前诊断较困难,主要依靠组织学检查,其局部复发与是否手术彻底切除密切相关。

为了探讨乳腺癌保留乳房综合治疗的原则和近期疗效,回顾分析实施保留乳房手术+术后化疗+术后放疗+雌激素受体试验阳性的32例Ⅰ、Ⅱ期乳腺癌患者的内分泌治疗随访。32例全部生存,1例同侧复发,所有病例乳房外形正常。初步研究结果提示,乳腺癌的保留乳房治疗是一种需多科密切配合的综合性治疗手段,可成为早期乳腺癌的主要治疗方法。     

Giant phyllodes tumor in both breasts:one case report and literature review

Breast phyllodes tumor (BPT),which is composed of epithelial cells and fibrous connective tissue,is a special type of tumor and yet not unified in biological behavior and histological classification,with high risk of recurrence and potential metastasis.BPT in one side has high incidence in clinic while BPT in both sides is rarely found.We treated one patient with giant BPT in both sides and reported as follows. 1 Case report The patient,female,aged 49,was admitted due to a rapidly increased lump in the right breast in June 2010,and she complained that the lump had increased from the size of "an egg" to the size of "a basketball" in August and had then been treated as suspected inflammation with anti-inflammatory treatment before admission but failed.Physical examination on admission showed an about 35 cm× 32 cm ×33 cm huge lump in the right breast,firm and poorly-movable,with reddish purple and mildly warm epidermis,swollen but not ulcerated (Fig.1).     

Histologic features predict local recurrence after breast conserving therapy of phyllodes tumors

Background: Pathologists can distinguish benign phyllodes tumors, which very rarely metastasize, from malignant phyllodes tumors, which metastasize in approximately one fourth of patients. However, whether these same histologic criteria can be used to predict the likelihood that a phyllodes tumor will locally recur after breast conserving therapy remains controversial.Study Design: Since few patients with malignant phyllodes tumors have been treated with breast conserving surgery in any individual series, the literature was reviewed using a Medline search.Results: After local excision, 21 (111/540), 46 (18/39), and 65 (26/40) of patients with benign, borderline, and malignant phyllodes tumors, respectively, recurred in the breast. Following wide local excision, 8 (17/212), 29 (20/68), and 36 (16/45) of patients with benign, borderline, and malignant phyllodes tumors recurred in the breast.Conclusions: Malignant phyllodes tumors are much more likely than benign phyllodes tumors to recur in the breast after breast conserving surgery. This high rate of local recurrence of borderline and malignant phyllodes tumors suggests that wide local excision is less than optimal therapy, and challenges us to look for methods to improve local tumor control.
