目的:评估血浆纤维蛋白原水平与乳腺癌新辅助化疗患者临床效果和预后的关系。方法:使用Clauss凝固法定量检测188例乳腺癌患者新辅助化疗前外周血中纤维蛋白原水平,根据纤维蛋白原水平将患者分为降低组、正常组或升高组。分析纤维蛋白原水平与病理完全缓解(pCR)的相关性,并进行预后分析。结果:月经状态与血浆纤维蛋白原水平相关(P<0.05)。纤维蛋白原水平是pCR的独立预测因素(P=0.002,95%CI:1.699~9.347)。Kaplan-Meier分析显示血浆纤维蛋白原水平升高组的无病生存期(DFS)和总生存期(OS)缩短(P<0.05)。单因素和多因素生存分析均显示分子分型、肿瘤大小、淋巴结状态、纤维蛋白原水平及pCR是DFS和OS的独立预后因素(P<0.05)。结论:血浆纤维蛋白原水平降低提示预后较好,血浆纤维蛋白原水平可能成为预测局部晚期乳腺癌患者新辅助化疗pCR和预后的生物学标志物。 相似文献

Serum markers and prognosis in locally advanced breast cancer 总被引:2,自引:0,他引:2

BACKGROUND: Locally advanced breast cancer (LABC) represents a heterogeneous subgroup of breast cancer with an often dismal outcome. Identifying prognostic factors has acquired great significance for the selection of optimal treatment in individual patients. METHODS: Between January 1993 and December 1997, 103 patients were treated in our institution with multimodality treatment consisting of neoadjuvant chemotherapy followed by surgery, adjuvant chemotherapy and radiotherapy; tamoxifen was added in hormone receptor-positive cases. In the search for prognostic factors well-established parameters (clinical, pathological and treatment-related) as well as new features with potential value (c-erbB-2, baseline serum levels of CA 15.3 and CEA) were included in the univariate and multivariate analysis. RESULTS: At a median follow-up of 92 months (range, 8-130), the estimated five-year cancer-specific overall survival (OS) and disease-free survival (DFS) were 71.34% and 57.7%, respectively. Among the 22 different variables studied, only 10 were significantly correlated with OS and DFS. In multivariate analysis five retained independent prognostic value for both OS and DFS: tumor grade, serum markers, features of inflammatory breast cancer (IBC), response to neoadjuvant chemotherapy and lymph node status. With cutoff values of 35 U/mL for CA 15.3 and 5 ng/mL for CEA, the probability of five-year OS (Cox hazard ratio 3.91, P = 0.0009) and DFS (Cox hazard ratio 2.40, P = 0.02) decreased from 78% to 52% and from 68% to 47%, respectively, when at least one of these markers was abnormal. CONCLUSIONS: Baseline serum levels of CEA and CA 15.3 emerged from this study as strong independent predictors of outcome in LABC, whose value adds to other established prognostic factors such as postoperative nodal status, IBC, histological grade and response to neoadjuvant chemotherapy. 相似文献

BackgroundSubtypes defined by hormonal receptor (HR) and HER2 status have not been well studied in inflammatory breast cancer (IBC). We characterized clinical parameters and long-term outcomes, and compared pathological complete response (pCR) rates by HR/HER2 subtype in a large IBC patient population. We also compared disease-free survival (DFS) and overall survival (OS) between IBC patients who received targeted therapies (anti-hormonal, anti-HER2) and those who did not.Patients and methodsWe retrospectively reviewed the records of patients diagnosed with IBC and treated at MD Anderson Cancer Center from January 1989 to January 2011. Of those, 527 patients had received neoadjuvant chemotherapy and had available information on estrogen receptor (ER), progesterone receptor (PR), and HER2 status. HR status was considered positive if either ER or PR status was positive. Using the Kaplan–Meier method, we estimated median DFS and OS durations from the time of definitive surgery. Using the Cox proportional hazards regression model, we determined the effect of prognostic factors on DFS and OS. Results were compared by subtype.ResultsThe overall pCR rate in stage III IBC was 15.2%, with the HR-positive/HER2-negative subtype showing the lowest rate (7.5%) and the HR-negative/HER2-positive subtype, the highest (30.6%). The HR-negative, HER2-negative subtype (triple-negative breast cancer, TNBC) had the worst survival rate. HR-positive disease, irrespective of HER2 status, had poor prognosis that did not differ from that of the HR-negative/HER2-positive subtype with regard to OS or DFS. Achieving pCR, no evidence of vascular invasion, non-TNBC, adjuvant hormonal therapy, and radiotherapy were associated with longer DFS and OS.ConclusionsHormone receptor and HER2 molecular subtypes had limited predictive and prognostic power in our IBC population. All molecular subtypes of IBC had a poor prognosis. HR-positive status did not necessarily confer a good prognosis. For all IBC subtypes, novel, specific treatment strategies are needed in the neoadjuvant and adjuvant settings. 相似文献

BACKGROUND:
The axillary pathologic complete response rate (pCR) and the effect of axillary pCR on disease‐free survival (DFS) was determined in patients with HER2‐positive breast cancer and biopsy‐proven axillary lymph node metastases who were receiving concurrent trastuzumab and neoadjuvant chemotherapy. The use of neoadjuvant chemotherapy is reported to result in pCR in the breast and axilla in up to 25% of patients. Patients achieving a pCR have improved DFS and overall survival. To the authors' knowledge, the rate of eradication of biopsy‐proven axillary lymph node metastases with trastuzumab‐containing neoadjuvant chemotherapy regimens has not been previously reported.METHODS:
Records were reviewed of 109 consecutive patients with HER2‐positive breast cancer and axillary metastases confirmed by ultrasound‐guided fine‐needle aspiration biopsy who received trastuzumab‐containing neoadjuvant chemotherapy followed by breast surgery with complete axillary lymph node dissection. Survival was evaluated by the Kaplan‐Meier method. Clinicopathologic factors and DFS were compared between patients with and without axillary pCR.RESULTS:
Eighty‐one patients (74%) achieved a pCR in the axilla. Axillary pCR was not associated with age, estrogen receptor status, grade, tumor size, initial N classification, or median number of lymph nodes removed. More patients with an axillary pCR also achieved a pCR in the breast (78% vs 25%; P < .001). At a median follow‐up of 29.1 months, DFS was significantly greater in the axillary pCR group (P = .02).CONCLUSIONS:
Trastuzumab‐containing neoadjuvant chemotherapy appears to be effective in eradicating axillary lymph node metastases in the majority of patients treated. Patients who achieve an axillary pCR are reported to have improved DFS. The success of pCR with concurrent trastuzumab and chemotherapy in eradicating lymph node metastases has implications for surgical management of the axilla in these patients.

目的:探讨乳腺癌分子分型在新辅助化疗疗效及预后预测中的作用.方法:收集漯河市中心医院收治的236例接受新辅助化疗患者的临床病理资料,分为Luminal A、Luminal B、Her-2阳性和三阴乳腺癌4种分子分型,分析分子分型与临床病理因素、新辅助化疗疗效及 5 年生存率的相关性.结果:236例患者中,107例(45.3%)为Luminal A亚型,47例(19.9%)为Luminal B亚型,27例(11.4%)为Her-2阳性亚型,55例(23.3%)为三阴乳腺癌亚型.Her-2阳性(25.9%)及三阴乳腺癌亚型(30.9%)的病理完全缓解(pCR)率明显高于Luminal亚型(Luminal A亚型 4.7%及Luminal B亚型 8.5%),差异有统计学意义(P<0.05).与Luminal亚型相比,Her-2阳性及三阴乳腺癌亚型具有更差的5年无病生存和总生存(P<0.01);获得pCR的乳腺癌患者的5年无病生存和总生存明显高于化疗后仍有癌残留的患者(P<0.05).结论:相对于Luminal亚型,Her-2 阳性和三阴乳腺癌亚型对新辅助化疗更为敏感,更易达到pCR;但是Her-2阳性和三阴乳腺癌亚型预后反而更差. 相似文献

目的 分析影响食管鳞癌新辅助放化疗联合手术患者预后相关因素。方法 回顾分析2007—2014年行新辅助放化疗联合手术的74例T3-4N0-1M0期食管鳞癌患者资料,Ⅱ期26例,Ⅲ期48例。Kaplan-Meier法计算OS率并Logrank法检验和单因素分析,Cox模型多因素分析。结果TRG1,TRG2,TRG3级的1、3年OS率分别为86%、50%,85%、50%,94%、86%(P=0.049)。pCR和非pCR者1、3年OS率分别为94%、87%和85%、52%(P=0.015)。淋巴结阴性和阳性1、3年OS率分别为97%、61%和57%、36%(P=0.015)。降期和非降期1、3年OS率分别为93%、70%和67%、17%(P=0.000)。多因素分析显示淋巴结状态及是否降期是影响预后因素(P=0.028、0.015)。结论 术后肿瘤缓解反应分级与患者预后密切相关,尤其pCR者可明显提高患者生存。淋巴结状态及是否降期是影响患者生存因素。 相似文献

目的: 探讨影响早期子宫颈癌患者预后的临床病理因素。方法:回顾性分析2009年11月1日至2014年10月31日经组织病理学确诊并在我中心接受手术治疗的ⅠB1~ⅡA2期子宫颈癌患者的情况。结果:共393例患者,随访至2016年12月31日,92.37%(363/393)完成随访。中位年龄45岁,高发年龄在40~50岁,占53.17%。90.63%(329/363)无瘤生存,2.48%(9/363)复发转移,6.89%(25/363)死亡。5年总体生存率(overall survival,OS)为92%,5年无瘤生存率(disease free survival,DFS)为89%。通过Cox比例风险回归分析发现,FIGO分期、肿瘤类型、间质浸润深度与OS相关,前两者还与DFS相关(P<0.05)。结论:子宫颈癌好发于40~50岁,鳞癌最常见。FIGO分期、肿瘤类型、间质浸润深度是影响患者预后的独立因素。虽然嗜神经侵袭(perineural invasion, PNI)不是影响预后的独立因素,但PNI的发生与淋巴结转移(lymph node metastasis, LNM)具有显著相关性。新辅助化疗可能使一些原本阳性的高危病理因素出现“假阴性”,对于术前接受过新辅助化疗者,应适当放宽术后辅助治疗的指征。 相似文献

目的 探讨新辅助放化疗联合手术治疗局部晚期食管鳞癌的临床疗效,并分析临床完全缓解率(cCR)与病理完全缓解率(pCR)的关系。方法 回顾性选取2001—2013年局部晚期胸段食管鳞癌患者 158例,全组均采用术前同期放化疗联合手术方式,化疗采用以铂类为基础化疗方案,放疗剂量为40 Gy,2.0 Gy/次,5 次/周。Kaplan-Meier法计算OS和DFS,Logrank法检验并单因素预后分析,Cox模型多因素预后分析。结果 全组患者的pCR率为41.1%。新辅助放化疗后 44例cCR患者中 32例(73%)达pCR,114例非cCR患者中 33例(28.9%)达pCR (P=0.000)。cCR预测pCR的敏感性、特异性分别为49.2%、87.1%,阳性、阴性预测值分别为72.7%、71.1%。3年总样本数为 53例。全组 3年OS、DFS分别为53.9%、48.6%,cCR的显著高于非cCR的(P=0.012、P=0.026),pCR的显著高于非pCR的(P=0.000、0.000)。多因素分析显示放化疗后病理反应和化疗方案是影响OS的因素。最常见≥3级急性不良反应为白细胞减少(34.2%)。结论 新辅助放化疗联合手术治疗局部晚期食管鳞癌可获得较高pCR率且不良反应可耐受,放化疗后cCR率与pCR率、OS密切相关。 相似文献
