肝细胞癌(HCC)是原发性肝癌的最主要类型。肝切除术可根治 HCC,使患者长期生存,但肝切除术受到一定的限制,主要在于:(1)肿瘤细胞恶性程度高、病情进展快,极易发生播散和转移;(2)HCC 患者多存在严重的肝硬化基础,因为肝功能失代偿而无法手术;(3)大部分肿瘤为多中心发生,很难切除完全。因此,切除率低和复发率高乃是制约手术治疗 HCC 患者的主要障碍。联合应用手术治疗与各种非手术治疗,多种方案的优化组合将成为综合治疗 HCC 患者的优先选择,提高疗效[1,2]。目前,常用的非手术治疗方法主要有肝动脉化疗栓塞(TACE)、局部消融、放射治疗、系统化疗和分子靶向治疗等。 相似文献

原发性肝癌的非手术治疗 总被引:1,自引:0,他引:1
我国原发性肝癌的治疗已取得显著的进展 ,肝癌切除术是目前根治性治疗的最有效手段 ,也是肝癌患者获得长期生存的最主要途径。然而手术切除在肝癌治疗中的作用也有一定的限度 ,主要表现在 :①肝癌恶性程度高 ,极易发生早期播散和转移 ;②我国原发性肝癌多伴有严重肝硬化 ,往往存在肝功能失代偿 ;③相当部分的原发性肝癌为多中心发生。因此 ,切除率低和复发率高乃是制约肝癌手术治疗的关键。据文献统计 ,能够接受手术切除治疗的肝癌患者仅占 2 0 %左右。对大多数肝癌患者 ,特别是中晚期患者 ,非手术治疗仍不失为重要的治疗方法。目前应用于肝癌的非手术治疗包括以下几个方面。一、肝动脉化疗栓塞肝动脉化疗栓塞术被公认为非手术治疗的首选方法 ,主要适用于不能切除的肝癌 ,特别是以右叶为主 ,或术后复发而无法手术切除者。对于不能根治切除的肝癌 ,经多次肝动脉化疗栓塞治疗后 ,如肿瘤明显缩小 ,应积极争取及时手术切除 ,使患者获得根治的机会。对于可一期根治性切除的肝癌 ,特别是直径小于5cm单个结节的肿瘤 ,宜积极予以及时手术切除 ,一般可不考虑术前应用肝动脉化疗栓塞。在切除术后辅以肝动脉化疗栓塞为主的综合治疗可清除可能残存的微小病灶并... 相似文献

原发性肝癌的治疗决策 总被引:5,自引:0,他引:5
原发性肝癌的病因主要是乙肝病毒及丙肝病毒,绝大多数肝癌患者合并有肝硬化.治疗手段的选择取决于肿瘤位置,转移及肝脏储备功能等因素.在合适的患者中,原发性肝癌首选治疗为肝切除术或肝移植.对不可手术的肝癌,则可选择局部消融治疗或肝动脉栓塞化疗.更晚期的患者只能作对症治疗.治疗选择的标准需以临床实验研究为基础. 相似文献

结直肠癌肝转移患者全身治疗是标准治疗,应该作为每一种治疗策略的初始,但局部治疗也发挥着重要价值.手术完全切除肝转移灶仍是目前能治愈结直肠癌和胃肠道神经内分泌肿瘤肝转移的最佳方法 .射频消融主要应用于那些不可切除或术后复发的局限性病灶,但受转移灶大小、数量和解剖位置的制约.立体定向放射治疗作为一种非手术的局部治疗是安全、有效的.微波消融、冷冻消融、高能聚焦超声刀、经皮穿刺瘤内注射无水乙醇、肝动脉栓塞或肝动脉化疗栓塞、肝动脉灌注化疗等也是重要的局部治疗手段,在患者的综合治疗中发挥重要作用.本文就以上内容作一综述. 相似文献

肝细胞癌(HCC)是最常见的原发性肝脏恶性肿瘤,手术切除及肝移植被认为是目前HCC可能的治愈方法,但仅30%~40%的患者能够受益。体部立体定向放射消融治疗(SABR)是近几年应用于体部恶性肿瘤治疗的一种新的精确放疗技术,以"少分次、大剂量"改变了传统的剂量分割模式,因其提高了体部恶性肿瘤的局部控制率、延长了总生存时间而受到重视。射波刀(CK)完成的SABR放疗技术具有高精度、无创伤的优点,可完成实时追踪照射(很好地解决了肿瘤的呼吸移动对治疗的影响),获得了理想的治疗有效率和局部无进展生存率、总生存率,同时3级以上放疗毒性反应发生率很低,是一种理想的治疗技术,为进一步提高HCC的临床疗效带来了新的希望。 相似文献

Opinion Statement Liver metastases, especially from colorectal primary cancers, are treatable and potentially curable. Imaging techniques such
as CT, MRI, and sonography have advanced in recent years and led to increased sensitivity and specificity in the diagnosis
of liver metastases.
Liver surgery also has been revolutionized in the past two decades. Dissections along nonanatomic lines have permitted the
resection of multiple lesions that previously might have been considered unresectable. We regard resection of a solitary hepatic
metastasis or up to four metastases from colorectal carcinoma as the best treatment for this condition.
In patients over 70 years of age and those with medical conditions preventing surgery, we endorse expectant follow-up as long
as the tumor remains stable. But if the tumor begins growing rapidly and local techniques cannot be used, we consider systemic
chemotherapy. In patients with progressive metastatic liver disease, we initiate systemic therapy or hepatic arterial infusion.
In young patients with metastatic disease, even when the disease is indolent or symptomatic, it may be difficult not to treat.
We use either local regional therapy (resection or regional infusion) or systemic chemotherapy followed by regional therapy.
In patients with neuroendocrine tumors metastatic to the liver, the first approach we use is not to treat because there may
be a long period of stable disease. We use Sandostatin (Sandoz Pharmaceuticals, East Hanover, NJ) to treat symptoms. If the
tumor progresses and symptoms cannot be controlled, these vascular tumors can be treated by embolization or chemoembolization,
with high expectations of response.
Newer approaches to liver metastases such as cryosurgery, chemoembolization, and interstitial radiation are also available.
Cryosurgery is an ablative procedure that has not been proven yet to be as effective as surgical removal of metastases. However,
in a situation where surgery cannot be performed, cryosurgery is an alternative. Chemoembolism has not been proven to be more
effective than systemic therapy for liver metastases, but it allows another regional approach. External localized radiation
can be used for patients who fail first-line treatment or in new protocols to delineate its value, perhaps in concert with
chemotherapy. We also consider offering external localized radiation in patients who fail first-line treatment, perhaps in
concert with chemotherapy. The usefulness of these techniques compared with surgery or regional therapy is being investigated. 相似文献

Liver metastases are the major cause of death coloroctal resection for cancer. Colorectal liver metastases are unique because of the potential for cure. Presently surgical resection is the gold standard of treatment. Complete R0 resection gives 5-year survival of up to 24-44%. Over the years there have been extensive efforts in devising new modalities of treatment for this disease. These include methods to increase the resectability such as portal after vein emolization & two-stage surgery, py with newer drugs and methods such chronotherapy & hepatic artery infusion chemotherapy, newer methods of radiotherapy, local ablative therapies such as cryoablation, radiofequency ablation, microwave ablation & laser interstitial thermal therapy, and biological therapy. Biological therapy is largely investigational, but holds great promise for the future. 相似文献

恶性肿瘤的治疗模式正在经历从传统的单项专科治疗向联合治疗,再向多学科综合治疗的转变。笔者提出了以整体医学观为基础的肿瘤多学科整体治疗(MDHT)模式以指导肿瘤综合治疗方案的设计与实施。MDHT模式涉及治疗目标、治疗方法和治疗疗程三个方面。以原发性肝癌为例,可以将整体治疗的靶向目标分为肿瘤局部病灶、区域病灶、系统病灶、器官基础病、全身内环境以及康复等六项基本目标。针对MDHT模式中各项治疗目标,可分别采用多种治疗方法的序贯疗法、同步治疗和交替疗法。整体治疗方案的实施是由不同治疗方法的多个治疗疗程来实现的。在肿瘤MDHT模式中,多学科治疗是治疗方式的体现,整体治疗是治疗目标的追求。MDHT的理念有助于指导多学科团队设计和实施肿瘤综合治疗方案。 相似文献

Hepatocellular carcinoma (HCC) is one of the most common malignancies worldwide with an annual occurrence of one million new cases. An etiologic association between HBV infection and the development of HCC has been established with a relative risk 200-fold greater than in non-infected individuals. Hepatitis C virus is also proving an important predisposing factor for this malignancy with an incidence rate of 7% at 5 years and 14% at 10 years. The prognosis depends on tumor stage and degree of liver function, which affect the tolerance to invasive treatments. Although surgical resection is generally accepted as the treatment of choice for HCC, new treatment strategies, such as local ablative therapies, transarterial embolization and liver transplantation, have been developed nowadays. With increasing detection of small HCCs from screening programs for cirrhotic patients, it is foreseen that locoregional therapy will play an important role in the near future. 相似文献

慢性肝炎肝纤维化中西医结合治疗问题 总被引:1,自引:0,他引:1
慢性肝炎肝纤维化主要由乙、丙型肝炎所致,合理治疗应包括抗病毒、调节免疫及抗肝纤维化治疗,有效抗病毒是治疗本病的关键,以西药为主辅以中药可提高疗效。当前在所谓的保(护)肝及对肝纤维化治疗方面药物虽多,但迄今尚乏特(有)效药物。研究表明:以"瘀血证"立论,重用丹参配黄芪活血化瘀为主,益气、舒肝、健脾中医中药对肝细胞炎症、坏死及肝纤维化等病变治疗具有良好作用。但面对众多慢性肝炎、肝纤维化患者,可用于临床的抗肝纤维化有效治疗措施仍很有限,而且目前"861"、"益肝康颗粒剂";强肝、扶正化瘀胶囊等有效中药投产者不多,尚需做进一步随机对照、盲法、大样本、多中心临床试验研究,并重视肝组织学治疗前后复查结果,进一步验证疗效。 相似文献

Since Barrett's esophagus is a precancerous condition,efforts have been made for its eradication by various ablative techniques.Initially,laser ablation was attempted in non-dysplastic Barrett's esophagus and subsequently,endoscopic ablation using photodynamic therapy was used in Barrett's patients with high-grade dysplasia who were poor surgical candidates.Since then,various ablative therapies have been developed with radiofrequency ablation having the best quality of evidence.Resection of dysplastic areas only without complete removal of entire Barrett's segment is associated with high risk of developing metachronous neoplasia.Hence,the current standard of management for Barrett's esophagus includes endoscopic mucosal resection of visible abnormalities followed by ablation to eradicate remaining Barrett's epithelium.Although endoscopic therapy cannot address regional lymph node metastases,such nodal involvement is present in only 1% to 2% of patients with intramucosal adenocarcinoma in Barrett esophagus and therefore is useful in intramucosal cancers.Post ablation surveillance is recommended as recurrence of intestinal metaplasia and dysplasia have been reported.This review includes a discussion of the technique,efficacy and complication rate of currently available ablation techniques such as radiofrequency ablation,cryotherapy,argon plasma coagulation and photodynamic therapy as well as endoscopic mucosal resection.A brief discussion of the emerging technique,endoscopic submucosal dissection is also included. 相似文献
