目的 探讨结直肠癌伴同时性肝转移患者的临床相关病理因素以及手术治疗.方法 回顾性分析1994年8月至2006年12月收治患者的临床资料及随访结果,比较结直肠癌无肝转移和有同时性肝转移患者的病理特点及不同程度肝转移患者和不同手术处理的预后.结果 2019例原发性结直肠癌患者中发生同时性肝转移者166例(8.10%).多因素分析显示:术前CEA水平、Ducks分期、肿瘤分化程度与浆膜浸润是同时性肝转移发生的高危因素;同时性肝转移术后1、3、5年生存率分别为69%、21%、9%;不同程度肝转移(H1、H2、H3)组间预后差异有统计学意义(X2=23.35,P<0.01).根治性手术切除组总体生存率明显高于姑息切除和未能切除组生存率(X2=21.18,P<0.01);姑息切除组和未切除组近期生存率差异有统计学意义(P<0.01),远期生存率差异无统计学意义(P=0.13).结论 结直肠癌伴同时性肝转移患者肝转移程度不同预后也不同.能够根治性切除的结直肠癌伴同时性肝转移预后较好,姑息切除原发病灶可提高近期预后和生活质量.     

胃癌肝转移患者的预后分析

胃癌肝转移患者的预后很差,因为胃癌肝转移患者常出现肝脏多发转移和其他病变,包括严重的淋巴结转移和（或）腹膜转移。回顾性分析1995年和2010年间共77例来自Kurume大学附属医院胃癌肝转移患者的临床资料,包括12例同时性转移患者,5例异时性转移患者。单因素分析结果显示,影响胃癌肝转移患者预后的因素为腹膜转移、组织学分型、淋巴结转移、胃大部切除术、全身化疗、转移结节数（小于3个）和肝动脉栓塞化疗（HAI）。多因素分析结果显示,组织学分型、化疗和肝动脉侵犯是影响胃癌肝转移患者预后的独立危险因素。5例异时性转移患者中有3例患者行肝切除后生存时间超过5年。     

外科治疗胃癌肝转移疗效分析

目的探讨外科治疗胃癌肝转移的方法与疗效。方法1996年1月至2003年12月间行外科治疗的胃癌肝转移患者25例，17例为同时性肝转移，8例为术后发现的异时性肝转移。其中单转移灶15例，多转移灶10例。行不规则肝切除16例，左外叶切除4例，左叶切除3例，右叶切除2例，术后行肝动脉灌注化疗9例，肝动脉化疗栓塞16例。结果1例同时性肝切除患者术后死于肺部感染、成人呼吸窘迫综合征，余24例均获随访，中位时间25(7—60)个月。胃癌肝转移灶切除后1、3年生存率为68．5％和29．8％，原发癌浸润表浅、淋巴结转移少、单转移灶、异时性转移及转移灶有包膜是影响生存率的有利因素。结论同时及异时性胃癌肝转移可经外科手术切除肝转移灶，但应注意手术指征的把握。     

大肠癌同时性肝转移外科治疗的预后因素分析

目的探讨大肠癌同时性肝转移及其与预后有关的危险因素,提高大肠癌肝转移的诊治水平。方法回顾性分析1994年8月至2004年2月间收治的大肠癌同时性肝转移106例的临床资料,对15项临床病理指标进行统计分析,并用单因素分析和Logistic回归分析与同期收治的无复发性肝转移的大肠癌1052例进行比较。同时对大肠癌肝转移行根治性切除、姑息性切除和探查性手术的生存状况用KaplanMeier法和COX回归方法进行分析比较。结果单因素分析显示,肠梗阻、腹水、盆腔结节、腹膜侵犯、浆膜浸润、周围脏器受累以及肿瘤长径、浸润肠壁的周径、浸润深度都与大肠癌同时性肝转移显著相关;Logistic回归分析发现,浸润深度、浆膜浸润、盆腔转移结节和腹水是影响大肠癌同时性肝转移最重要的因素。根治性切除57例(53.8%),姑息性切除39例(36.8%)和探查性手术后10例(9.4%)平均生存期和中位生存期分别为41.0和34.0个月、23.6和18.0个月以及16.5和12.0个月,三组差异有统计学意义(P=0.0095)。手术方式、肿瘤部位和盆腔结节是影响大肠癌同时性肝转移预后的主要因素。结论大肠癌浸润达浆膜、有盆腔转移结节和腹水者可能合并肝转移,根治性切除可以明显提高大肠癌同时性肝转移的生存率。     

结直肠癌肝转移的临床病理特征与术后生存关系分析

目的通过分析结直肠癌肝转移临床病理学特征与术后生存因素的相互关系,寻找更多更准确的能够影响预后的指标对预后生存的影响,为结直肠癌肝转移患者的治疗策略提供参考。方法回顾性分析第二军医大学东方肝胆外科医院2006年1月至2009年12月期间收治并经手术治疗的233例结直肠癌肝转移患者的临床资料,采用Kaplan-Meier法计算生存率及生存曲线,并进行单因素分析,采用log-rank法进行统计学检验。将经单因素分析对预后有统计学意义的危险因素带入COX多因素回归模型,计算独立预后因素。结果本组患者术后中位生存期为37.0个月,术后1、3及5年累积生存率分别为93.0%、61.0%、17.0%。接受根治性手术患者的术后中位生存期、3及5年累积生存率优于姑息性手术者:40.53个月比27.20个月、59.0%比29.0%、20.0%比0(P0.05)。对于总体生存期而言,单因素分析结果显示,手术方式、肝转移瘤切除术后首次复发时间、肝内转移灶数目、肝内转移灶最大直径、手术切缘、肝外不可切除转移灶及周围组织或器官侵犯、是否合并慢性肝病(慢性肝炎、脂肪肝、肝硬变)、术前血清CEA水平、CA19-9水平、是否为同时性肝转移、原发灶TNM分期、肝转移瘤生长位置和肝转移瘤包膜是否完整这13项是影响预后的因素(P0.05);COX多因素分析结果显示,姑息性手术方式、同时性肝转移、肝转移瘤生长位置广泛、肝转移瘤无完整包膜、肝内转移灶多发、肝内转移灶最大直径3 cm、存在肝外不可切除转移灶及周围组织或器官侵犯和未合并慢性肝病(慢性肝炎、脂肪肝、肝硬变)这8项因素是对结直肠癌肝转移患者术后生存产生影响的独立危险因素(P0.05)。结论手术治疗可以使结直肠癌肝转移患者获得长期生存,姑息性手术方式、同时性肝转移、肝转移瘤生长位置广泛、肝转移瘤无完整包膜、肝内转移灶多发、肝内转移灶最大直径3 cm,存在肝外不可切除转移灶及周围组织或器官侵犯、未合并慢性肝病(慢性肝炎、脂肪肝、肝硬变)等是影响结直肠癌肝转移患者术后预后的独立危险因素。

Analysis of hepatic resection of metastasis originating from gastric adenocarcinoma

Few patients with metastatic gastric cancer have disease that is amenable to curative surgery. Thus far, little is known about liver surgery for metastases arising from gastric adenocarcinoma and prognostic factors. Of 73 patients operated on between 1980 and 1999 for noncolorectal, non-neuroendocrine hepatic metastases, 15 underwent liver resection for gastric adenocarcinoma metastasis. Ten patients underwent synchronous hepatic resection and five underwent metachronous hepatic surgery after a median diseasefree interval of 10 months (range 6.1 to 47.3 months). None of the patients died within the first 30 days after surgery, and the in-hospital mortality rate was 6.7%. Among patients in the synchronous group, 26.7% experienced major complications mainly associated with gastric surgery. Overall median survival was 8.8 months (range 4 to 51 months); two patients survived more than 3 years. Univariate analysis reealed that the appearance of liver metastasis synchronous vs. metachronous), the distribution of liver metastases (unilobar vs. bilobar), and the primary tumor site (proximal vs. distal) were marginally signifiant predictive factors regarding overall survival. Because of its high morbidity, synchronous liver resecion for metastases originating from gastric adenocarcinoma is rarely followed by survival longer than 2 years. Primary tumor localization within the proximal third of the stomach and bilobar liver involvement appear to be predictive of poor outcome. On the other hand, curative resection of metachronous liver metastases may allow long-term survival in selected patients.     

Outcome of hepatic resection for metastatic gastric cancer

The role of hepatic resection for metastatic gastric cancer is less well defined due to the tendency of gastric cancer to widely metastasize. The purpose of this study is to examine the beneficial effect of hepatic resection in patients with metastatic gastric cancer. The clinicopathologic features and long-term results of 11 patients who underwent hepatic resection for metastatic gastric cancer from January 1988 to December 1996 at Seoul National University Hospital were analyzed retrospectively. All resected hepatic metastases were solitary lesions. Among eight patients with synchronous hepatic metastases, one patient with early gastric cancer and lymph node metastases (T1N2M1) remained alive for 8 years 6 months after hepatic resection without recurrence. Among three patients with metachronous hepatic metastases, two patients with advanced gastric cancer and lymph node metastases (T3N2MO, T2N1MO at the initial operation, respectively) survived 8 years 6 months and 3 years after hepatic resection, respectively. Median survival times of synchronous and metachronous hepatic metastases were 13.0 and 74.3 months, respectively. In solitary hepatic metastatic lesions from gastric cancer, surgical resection should be considered as one of the treatment options.     

The utility of estrogen receptor, progesterone receptor, and Her-2/neu status to predict survival in patients undergoing hepatic resection for breast cancer metastases

BACKGROUND: Hepatic metastases from breast cancer signal a dismal prognosis, with a median survival of 9.5 months. METHODS: Twenty breast cancer patients with liver metastases underwent hepatic resection, biopsy, or ablation between 1995 and 2004. Hormone receptor status and Her-2/neu expression of primary and metastatic tumors were correlated with overall survival. RESULTS: At a mean follow-up of 39 months after hepatic resection, median survival was 32 months. Patients undergoing anatomic resection with or without ablation lived significantly longer than those undergoing more limited resections (46 vs. 25 months, P = .016). Survival was significantly greater in patients with estrogen receptor (ER)-positive primary (P = .02) and metastatic (P < .004) tumors, Her-2/neu-positive metastases (P = .02), 50 years at metastasectomy (P = .02). CONCLUSIONS: The ER status of the primary tumor and ER and Her-2/neu status of hepatic metastases, in addition to other clinical factors, may help select patients who would benefit from hepatic metastasectomy.     

Hepatic Resection for Metastatic Tumors From Gastric Cancer

OBJECTIVE: To assess the surgical results and clinicopathologic features of hepatic metastases from gastric adenocarcinoma to identify patients with a better probability of survival. SUMMARY BACKGROUND DATA: Many studies have reported the benefit of hepatic resection for metastatic tumors from colorectal cancer. However, indications for a surgical approach for gastric adenocarcinoma involving the liver have not been clearly defined. METHODS: Ninety (11%) of 807 patients with primary gastric cancer were diagnosed with synchronous (n = 78) or metachronous (n = 12) hepatic metastases. Of these, 19 underwent 20 resections intended to cure the metastatic lesion in the liver. The clinicopathologic features of the hepatic metastases in, and the surgical results for, the 19 patients were analyzed. RESULTS: The actuarial 1-year, 3-year, and 5-year survival rates after hepatic resection were, respectively, 77%, 34%, and 34%, and three patients survived for more than 5 years after surgery. Solitary and metachronous metastases were significant determinants for a favorable prognosis after hepatic resection. Pathologically, a fibrous pseudocapsule between the tumor and surrounding hepatic parenchyma was found in 13 of the 19 patients (68%). The presence of a peritumoral fibrous pseudocapsule and a well-differentiated histologic type of metastatic nodule were significant prognostic factors. Factors associated with the primary lesion were not significant prognostic determinants in patients who underwent curative resection of the primary cancer. CONCLUSIONS: Solitary and metachronous metastases from gastric cancer should be treated by a surgical approach and confer a better prognosis. A new prognostic factor, the presence of a pseudocapsule, may be helpful in defining indications for postoperative adjuvant treatment.     

胃癌肝转移的手术治疗

目的 探讨胃癌肝转移行肝切除术的适应证及疗效。方法 对1990年1月至1999年11月间施行肝切除的24例胃癌肝转移患的临床资料进行回顾性分析。结果 本组同时性肝转移19例，异时性转移5例。共施行肝段叶切除8例，肝部分切除16例；19例同时性肝转移患均在肝切除的同时加行根治性胃切除术。术后并发肝昏迷死亡l例。手术死亡率为4．2％。全组22例获得随访。术后1年、3年和5年生存率分别为45．5％、18．2％和9．1％。生存分析显示，肝切除术后的生存率不仅与胃癌原发灶的分化程度、有无浆膜面浸润和淋巴结转移有关，而且与肝转移灶的数目及其在肝脏内的分布范围有关。结论对于胃癌孤立性肝转移患，其原发病灶可根治切除的应积极采用手术治疗，部分患可获长期生存。     

Benefits and limits of hepatic resection for gastric metastases

BACKGROUND: The significance of hepatic resection for gastric metastases has been controversial. METHODS: Forty consecutive patients undergoing hepatic resection for gastric metastases were reviewed to examine the benefits and the limits of hepatic resection using univariate and multivariate analyses. RESULTS: The overall survival was 27% at 2 years, 18% at 5 years, and 11% at 10 years. Six patients survived more than 5 years. All of the 6 patients underwent anatomical hepatic resection more extensive than segmentectomy, with sufficient resection margin. There were recurrences in 31 patients, and 94% of the recurrences were in the remaining liver. Univariate analysis showed time of hepatic metastases (P = 0.0078) and resection margin (P = 0.024) as significant prognostic factors. Multivariate analysis indicated that only time of hepatic metastases was an independent prognostic factor that influenced survival. CONCLUSIONS: These results suggest that in patients with synchronous metastases we should consider patient selection more strictly, and that in patients with metachronous metastases we should perform anatomical hepatic resection with sufficient resection margin.

Resection of brain metastases from non-small-cell lung carcinoma. Results of therapy. Memorial Sloan-Kettering Cancer Center Thoracic Surgical Staff.

The treatment of patients with a solitary brain metastasis has been evolving, with most centers recommending resection in patients with good performance status. To evaluate the results of resection of brain metastases from non-small-cell lung cancer, we reviewed our 16-year experience with 185 consecutive patients undergoing resection of brain metastases from 1974 to 1989, inclusive. There were 89 men and 96 women; ages ranged from 34 to 75 years (median 54). Sixty-five (35%) had synchronous and 120 (65%) metachronous brain metastases. Discounting the brain metastasis, 68 patients (37%) had stage I, 13 (7%) stage II, 62 (33%) stage IIIA, 30 (16%) stage IIIB, and 12 (6%) stage IV carcinoma. There was no significant difference in age, locoregional stage (TN), or histologic features in patients with synchronous versus metachronous lesions. The overall survival rates (n = 185) were as follows: 1 year, 55%; 2 years, 27%; 3 years, 18%; 5 years, 13%; and 10 years, 7% (median 14 months). There was no significant difference in survival between patients with synchronous and metachronous lesions. To evaluate the impact of locoregional stage and treatment of the primary site, we analyzed only those patients with synchronous brain metastases. Multivariate analysis demonstrated that locoregional stage had no significant effect on survival (p = 0.97), but complete resection of the primary disease significantly prolonged survival (p = 0.002). Therefore complete resection, and not stage, of the locoregional primary lesion is the primary determinant of survival in patients undergoing resection of brain metastases from non-small-cell lung cancer.
