双侧原发性乳腺癌的预后影响因素分析

目的：研究双侧原发性乳腺癌的预后及其影响因素。方法：对经病理证实的30例双侧原发性乳腺癌患者进行分析。结果：腋淋巴结无转移患者的5年生存率（64．7％）明显高于腋淋巴结转移的患者（30．8％）。肿瘤直径＜2cm的患者5年生存率（62．5％）明显高于肿瘤直径≥2cm的患者（45．5％）。ER受体阳性患者的5年生存率（66．7％）明显高于ER受体阴性患者（38．9％）。结论：双侧原发性乳腺癌的预后取决于腋窝淋巴结有无转移，肿瘤大小以及ER受体是否阳性。其中腋淋巴结有无转移是影响预后的一个重要指标。     

人表皮生长因子受体2表达对腋淋巴结阳性和阴性乳腺癌患者预后的不同影响

目的 探讨人表皮生长因子受体2(Her-2)表达在腋淋巴结阳性和阴性乳腺癌患者预后中的意义.方法 采用抗Her-2单克隆抗体CB11进行免疫组化,检测981例原发性乳腺癌肿瘤组织Her-2蛋白的表达,分析其与乳腺癌预后的关系.结果 981例原发性乳腺癌Her-2蛋白的阳性表达率为19.7%(193/981),Her-2表达水平与乳腺癌患者的发病年龄、雌激素受体(ER)和孕激素受体(PR)表达状态明显相关(P<0.05).单因素分析显示,在腋淋巴结阳性的乳腺癌患者中,Her-2表达与预后显著相关,Her-2阳性者的5年无病生存(DFS)率和5年总生存(OS)率分别为48.8%和55.2%,Her-2阴性者分别为66.9%和76.4%,差异均有统计学意义(P<0.01).而在腋淋巴结阴性的患者中,Her-2表达与患者的5年DFS率和5年OS率均无显著相关性(P>0.05).多因素分析显示,在腋淋巴结阳性的乳腺癌患者中,Her-2表达水平是影响乳腺癌OS的独立因素,但不是影响乳腺癌DF5的独立因素.结论 在腋淋巴结阳性乳腺癌患者中,Her-2表达水平是重要的预后因素.

目的:探讨乳腺癌患者雌孕激素受体状态分布及与临床指标的关系。方法:采用SP二步法对1393例乳腺癌患者的术后肿瘤石蜡标本进行雌、孕激素受体检测,并与患者的年龄、月经情况、原发肿瘤病理类型和腋淋巴结转移状况相结合进行分析。结果:1)ER和PR的表达呈显著正相关(P<0.0001);2)ER(+)、PR(+)及PR(-)表达率和年龄分布无关(P>0.05),≤39岁年龄组ER(-)表达率明显高于其他年龄组(P<0.001);3)绝经后ER(+)率高于绝经前患者(P<0.0001),PR(+)率低于绝经前患者(P<0.0001);4)组织病理学类型和ER、PR之间关系无显著差异(P>0.05);5)无腋淋巴结转移患者的ER(+)、PR(+)表达率显著高于有转移者(P<0.0001),ER(-)、PR(-)表达率低于有腋淋巴结转移者(P<0.0001)。结论:乳腺癌患者ER、PR的分布有一定的规律,可作为制定综合治疗方案的依据,同时对判断预后有一定意义。     

140例乳腺大汗腺癌的临床病理特征及预后分析

  目的  分析乳腺大汗腺癌的临床病理特征及预后影响因素。  方法  收集1984年5月至2008年12月天津医科大学附属肿瘤医院乳腺科收治的140例乳腺大汗腺癌患者的临床资料, 对其临床特征及影响预后的因素进行分析。  结果  140例乳腺大汗腺癌患者5年、10年总生存率分别为84.0%、63.0%;5年、10年无瘤生存率分别为73.0%、61.0%。术后腋窝淋巴结阳性率达67.9%, 肿瘤大小和肿瘤位置与AC腋窝淋巴结转移有关。肿瘤直径2 cm组淋巴结转移率明显高于≤2 cm组(80.9%vs.49.0%, P=0.000 2);肿瘤位于中央区的患者淋巴结转移率明显高于位于外侧区和内测区的患者(87.5%、70.5%、48.7%, P=0.002)。ER、PR、HER-2的阳性表达率分别为36.5%、37.5%、32.9%。经单因素生存分析, 肿瘤大小、病理分期、腋淋巴结转移数、淋巴结外软组织转移(ETE)是影响预后的因素(P=0.005, 0.024, 0.001, 0.009)。经Cox多因素分析, 肿瘤大小是影响预后的独立因素(P=0.007)。  结论  乳腺大汗腺癌的ER、PR表达率低, 腋淋巴结转移率较高, 但其生存率较高, 所以对于乳腺大汗腺癌患者, 行积极全面的综合治疗可提高患者生存率。      

同期腋窝转移淋巴结受体检测在激素受体阴性乳腺癌中的临床意义

  目的   探讨同期腋淋巴结转移病灶雌激素受体（estrogen receptor,ER）和孕激素受体（progesterone receptor,PR）补测在激素受体阴性浸润性乳腺癌中的临床意义。   方法   观察2012年7月至2013年1月,重庆医科大学附属第一医院内分泌乳腺外科门诊随访及住院患者中补测激素受体阴性乳腺癌同期腋淋巴结转移病灶ER和PR的表达情况,所有标本（包括原发癌病灶及同期腋淋巴结转移病灶）的免疫组织化学检测均由重庆医科大学病理检测中心进行,根据检测报告,原发病灶阴性而腋淋巴结转移病灶ER和/或PR阳性者补加内分泌治疗。   结果   56例激素受体阴性乳腺癌中,同期腋淋巴结转移病灶ER阳性8例（14.3%）,PR阳性2例（3.6 %）,ER和PR均阳性3例（5.4%）,共13例（23.3%）因补查腋淋巴结转移病灶ER和/或PR变阳性而在随访中加用内分泌治疗。肿瘤原发病灶与腋转移淋巴结ER和PR均阴性43例（76.7%）,即肿瘤原发癌病灶与腋转移淋巴结ER和PR均为阴性表达的总符合率为76.7%,不一致率为23.3%。   结论   受体阴性浸润性乳腺癌原发病灶与腋淋巴结转移病灶ER和PR表达具有一定的不一致性,对原发癌病灶激素受体阴性乳腺癌患者应检查其同期腋淋巴结转移病灶受体的表达,可能筛查出原发病灶受体阴性而复发转移病灶受体阳性患者,及时加用内分泌治疗,提高该类患者的疗效,亦可解释部分激素受体阴性而内分泌治疗也有一定疗效的原因。      

Alterations in Hormonal Receptor Expression and HER2 Status between Primary Breast Tumors and Paired Nodal Metastases: Discordance Rates and Prognosis

Background: We aimed to evaluate the estrogen receptor (ER), progesterone receptor (PR), and humanepidermal growth factor receptor 2 (HER2) expression discordance in matched pairs of primary breast cancerand lymph node metastasis specimens and determine the effect of discordance on prognosis. Materials andMethods: Among all patients diagnosed with lymph node metastases from 2004 to 2007, primary tumors andpaired lymph node metastases were resected from 209 patients. The status of ER, PR, and HER2 expressionwas analyzed immunohistochemically in 200, 194, and 193 patients, respectively. Discordance was correlatedwith prognosis. Results: Biomarker discordance between primary tumors and paired lymph node metastaseswas 25.0% (50/200) for ER status, 28.9% (56/194) for PR status, and 14.0% (27/193) for HER2 status. ERpositivity was a significant independent predictor of improved survival when analyzed in primary tumors andlymph node metastases. Patients with PR-positive primary tumors and paired lymph node metastases displayedsignificantly enhanced survival compared to patients with PR-positive primary tumors and PR-negative lymphnode metastases. Patients with ER- and PR-positive primary tumors and paired lymph node metastases whoreceived endocrine therapy after surgery displayed significantly better survival than those not receiving endocrinetherapy. Similalry treated patients with PR-negative primary tumors and PR-positive paired lymph nodemetastases also displayed better survival than those not receiving endocrine therapy. Conclusions: Biomarkerdiscordance was observed in matched pairs of primary tumors and lymph node metastases. Such cases displayedpoor survival. Thus, it is important to reassess receptor biomarkers used for lymph node metastases.     

Obesity and body fat distribution and breast cancer prognosis

This study addresses the effect of obesity and body fat distribution on axillary lymph node involvement, tumor size, and estrogen receptor (ER) level in breast cancer patients. Anthropometric measurements were prospectively obtained on 248 consecutively and newly diagnosed women with invasive breast cancer. The anthropometric measurements evaluated were abdomen, thigh, subscapular, and midaxillary skinfolds; weight; and height. Weight and Quetelet Index (kg/m2) were significantly (P = 0.001) associated with lymph node involvement in postmenopausal patients. The abdomen:thigh skinfold ratio was significantly higher in premenopausal patients (P = 0.004) and postmenopausal (P = 0.03) without axillary node involvement compared with women with 4+ axillary node involvement. The abdomen:thigh skinfold was higher (P = 0.05) in women with smaller breast cancers (less than 2.0 cm) and higher ER levels. Weight and Quetelet Index did not affect tumor size or ER level. This study demonstrated that obese postmenopausal women who developed breast cancer tend to have more axillary node involvement than their leaner counterparts. Generalized obesity did not affect tumor size or ER level. Premenopausal and postmenopausal women with upper body fat distribution appear to be a subset of women who have a more favorable prognosis as measured by less lymph node involvement, smaller tumors, and higher levels of ER in their tumors.     

Primary tumor site, size, patients age and axillary lymph nodes in breast cancers

This study considers the correlations between some characteristics of the primary tumor and level of lymph node involvement in 185 primary breast cancers. The average number of lymph nodes was higher in N+ women than in N- women. Primary tumors with a diameter of more than 4 cm yielded the highest mean number of lymph nodes (17.5). The risk of developing lymph node metastases was fourfold in tumors with a diameter greater than 2 cm when compared to those with a diameter less than or equal to 2 cm. The most commonly metastasized lymph node level, in both large and small tumors, was the first; however, one-fifth of the patients had simultaneous lymph node metastasis in all three axillary levels. Although the left breast was the most affected (58.9%), there was no evidence of a different risk of metastasis between the two breasts; 34.1% of the tumors were multifocal. Lymph node involvement was higher in women under 50 years of age with a primary tumor larger than 2 cm.     

Tumor dimension and prognosis in surgically treated lung cancer: for intentional limited resection

Tumors with a maximum dimension of 3 cm are categorized as T1, whereas those greater than 3 cm are T2 by TNM classification. Some physicians suggest that early-stage peripheral lung cancer should have a maximum tumor diameter of 2 cm and that limited surgery (segmentectomy without lymph node dissection) is acceptable for the patients. In this study, the relationship between the tumor dimension and prognosis was analyzed in 207 patients with surgically treated primary non-small-cell lung cancer (SCLC). The 5-year survival rate of those with tumors 3 cm or less and without lymph node (LN) metastases was 86%, which was significantly higher than that of those with tumors more than 3 cm and without hilar and mediastinal LN metastases (65%) (p < 0.05). However, 33% of the patients with tumors 3 cm or less had LN metastases, and the 5-year survival rate did not differ between those with tumors 3 cm or less (60%) and those with tumors more than 3 cm (54%). Twenty-eight percent of patients with tumors 2 cm or less had LN metastases, and the 5-year survival rate of the patients with tumors 2 cm or less was 62%. The 5-year survival rate of those with tumors 2 cm or less and without LN metastases was 88%. Forty-six patients with tumors 2 cm or less included 5 cases with an intrapulmonary metastasis in the same lobe (11%). In conclusion, a size of 3 cm is an appropriate boundary as the T factor. Because those with tumors 2 cm or less have a relatively high percentage of LN metastases, intraoperative frozen sections of LN should be considered for those undergoing limited surgery for primary non-SCLCs 2 cm or less. Intrapulmonary metastases also should be considered for those undergoing limited surgery even if the maximum dimension of the primary tumor is less than 2 cm.     

Breast conservation in the treatment of early breast cancer. A 20-year follow-up

Two hundred sixty-three patients with unilateral primary breast cancer, treated by local excision of the primary tumor and radical radiation therapy between 1954 and 1969, were followed up for a minimum of 10 years and a maximum of 20 years. The treatment plan delivered 4500 rad in fractions of orthovoltage irradiation to five fields: tangential breast fields, axilla with posterior axillary field, parasternal and supraclavicular, with a subsequent boost of 1000 rad to the primary tumor site, axilla, and supraclavicular fossa. Patients were clinically staged using the TNM (UICC) system; 115 patients had tumors less than 2 cm in diameter and a clinically negative axilla (T1N0N1a), 96 had tumors 2 to 5 cm in diameter with a clinically negative axilla (T2N0N1a), and 52 had tumors less than 5 cm in diameter and clinical axillary lymph node metastases (T1T2N1b). The actuarial relapse-free survival of patients with T1N0N1a tumors was 72% at 5 years, 59% at 10 years, and 47% at both 15 and 20 years. The relapse-free survival of patients with T2N0N1a tumors was not statistically different (P greater than 0.05). A significantly worse survival was observed in patients with clinical axillary lymph node metastases (T1T2N1b), with a survival of 37% at 5 years, 29% at 10 years, 23% at 15 years, and 22% at 20 years, when compared with patients with clinically negative lymph nodes (P less than 0.01). Locoregional relapse occurred in 22%, at 10 years, of those patients with T1 or T2N0N1a tumors and 52% of the patients with T1T2N1b tumors. The pattern of locoregional relapses indicated that approximately 50% occur at least 5 years after treatment; this contrasts with the pattern of early locoregional relapse after mastectomy. The commonest sites of relapse were in the breast in 19% and axilla in 6% of patients with T1 or T2N0N1a tumors. There was no attenuation of the radiation dose administered at the site of a subsequent relapse. Surgery for radiation failure produced a 42% crude relapse-free survival at 5 years after salvage mastectomy in those patients originally treated for T1 or T1N0N1a tumors. The results of this study suggest that a significant proportion of patients relapse locally over a prolonged period after breast conservation. The evolution of new radiation techniques may provide better locoregional control and early salvage surgery may result in improved long-term survival.

Expression of estrogen,progesterone and epidermal growth factor receptors in primary and metastatic breast cancer

The prognostic value of epidermal growth factor receptor (EGFR) expression and its biological role in estrogen receptor-positive (ER⁺) and ER-negative (ER^?) primary breast cancer is controversial. In this study, distributions of ER, progesterone receptor and EGFR have been established using immunohisto-chemistry in both primary breast tumors and their matched axillary lymph node metastases of 26 patients or their matched distant metastases of 2 patients. In addition, 5 patients with bilateral breast cancer were studied. ER⁺ tumor cells were detected in 22 (69%) and EGFR⁺ tumor cells were detected in 11 (34%) primary breast carcinomas. Expression of ER and EGFR was inverse regarding the individual tumor cells in both primary tumors and metastases. Relationship of EGFR expression with poorly differentiated and large breast tumors was observed. Furthermore, primary tumors with a predominant lobular component were ER⁺ and, with one exception, EGFR^?. Invasive ductal carcinomas were more frequently EGFR⁺. No apparent differences in receptor expression were observed between primary tumors and lymph node metastases or chro-nously or metachronously occurring bilateral breast cancers. Only one ER⁺ primary tumor showed a switch to EGFR expression in the involved lymph node. Our study shows that a shift in receptor phenotype between primary tumors and lymph node metastases is a rare event and, thus, additional analyses of involved lymph nodes will not likely serve as a better predictor for response to anti-estrogen therapy. We conclude that expression of EGFR is not a prerequisite for development of metastases. © 1995 Wiley-Liss, Inc.

  目的  探讨分化型甲状腺癌是否为女性激素依赖性肿瘤，分析ER、PR的表达与分化型甲状腺癌患者的肿瘤大小、组织学类型、有否淋巴结转移、性别、年龄等的关系。  方法  应用免疫组织化学方法（SP法）检测分析正常甲状腺、甲状腺良性肿瘤和分化型甲状腺癌组织中ER、PR的表达。  结果  分化型甲状腺癌中ER和PR阳性表达分别为19.3%（10/52）和30.8%（16/52），其表达比正常甲状腺与良性肿瘤组织多，有显著性差异（P < 0.01）。分化型甲状腺癌的肿瘤直径>1 cm的ER、PR阳性率明显高于≤1 cm的病例，有显著性差异（P < 0.01）。而ER和PR的表达与患者的性别、年龄、组织类型和淋巴结转移无关。  结论  分化型甲状腺癌组织中ER和PR的表达较正常甲状腺、甲状腺良性肿瘤组织高，有显著差异性（P < 0.01），且肿瘤直径>1 cm者的ER和PR表达高于肿瘤直径≤1 cm者，揭示分化型甲状腺癌可能是雌激素和孕激素依赖性肿瘤。      

Comparison of ER,PR & HER-2/neu (C-erb B 2) Reactivity Pattern with Histologic Grade,Tumor Size and Lymph Node Status in Breast Cancer

Introduction: Carcinoma of the breast is the most common malignancy of women in Karachi. The currentstudy was conducted with the objective of assessing estrogen receptor (ER), progesterone receptor (PR) andHER-2/neu reactivity patterns of mammary cancers for correlation with histologic grade, tumor size and lymphnode metastasis. Materials and methods: One hundred and fifty modified mastectomy specimens received atthe section of histopathology, Aga Khan University Hospital, were selected using a non-probability samplingmethod. Results: Mean age of the patients was 48.3 years (95%CI 46.5, 50.2). The left breast was more commonlyinvolved (57%). Tumor size ranged from 0.3 to 15.0 cm; 12% were ≤2.0 and 35.3% were ≥ 5.0 cm in diameter.The predominant morphology was infiltrating ductal carcinoma (85.3%). The majority of the cases presentedas grade II (55.3%) lesions with tumor necrosis (70%) and lymph node involvement (71.3%). ER and PR werepositive in 32.7% and 25.3% cases respectively. HER-2/neu was positive (3+) in 24.7%. ER positivity increasedand HER-2/neu positivity decreased with rising age. ER and PR expression was significantly lower in HER-2/neu positive as compared with HER-2/neu negative tumors (ER 83.8% vs 69.8%; PR 91.9% vs 77.8%). In theHER-2/neu positive tumors, ER and PR expression in high grade tumors was significantly decreased comparedwith intermediate grade tumors (ER 5.6% vs 10.5; PR 0% vs 5.3%). ER expression in the HER-2/neu positive,large sized tumors was also significantly decreased compared with smaller tumors (ER 6.3% vs 11.8). Conclusions:ER and PR expression in breast cancers in the current study was found to be comparable to publishedinternational data, but the frequency of HER-2/neu expression was higher, possibly reflecting a young age atdiagnosis. Assessment of prognostic markers for the clinical management of breast cancer patients is stronglyadvocated to provide best therapeutic options.     

表皮生长因子受体表达与乳腺癌激素受体水平和预后的关系

应用免疫组化ＡＢＣ方法研究７５例乳腺癌冰冻组织表皮生长因子受体（ＥＧＦＲ）的表达，结合临床资料和ＥＲ、ＰＲ测定结果进行分析，探讨ＥＧＦＲ表达与乳腺癌预后的关系。结果表明，ＥＧＦＲ阳性３０例（４０％），ＥＧＦＲ表达与肿瘤大小、腋淋巴结状况，临床分期和年龄无关，与ＥＲ、ＰＲ存在着显著的负相关（Ｐ＜０．００５）。全组中位随诊时间为６０个月，ＥＧＦＲ阳性组术后总生存率明显低于阴性组（Ｐ＜０．００１）。在无腋淋巴结转移的病例中，ＥＧＦＲ阳性组和阴性组术后生存情况也有显著差异（Ｐ＜０．０１），提示ＥＧＦＲ表达与乳腺癌不良的预后有关。调整分析乳腺癌有关的预后因素，各组病例中均以ＥＧＦＲ表达阳性组的预后为差，说明ＥＧＦＲ对乳腺癌预后具有独立的作用，不受其他因素的影响。经Ｃｏｘ模型多因素分析显示，ＥＧＦＲ和腋淋巴结受累与否是对乳腺癌术后生存情况有显著性影响的两个因素。
