目的　探讨大肠癌肝转移因素及对策。方法　对我院 1990年 1月～ 1997年 12月收治的 117例大肠癌肝转移病例 ,进行血清AFP、CEA、HBsAg、肝脏B型超声及CT检查 ,分别施行大肠癌根治、大肠癌根治加肝转移灶切除或微波固化、大肠癌姑息切除 ,大部分病例加行门静脉和区域动脉插管化疗。结果　发现肝转移多见于原发病灶位于乙状结肠 (5 5 .6 % )、有周围淋巴结转移 (76 .1% )、肿瘤超过肠腔一半 (70 .1% ) ,且直径大于 3cm(72 .6 % )、没有明显的肝硬化 (86 % )者。大肠癌根治加肝转移灶切除加门静脉和区域动脉插管化疗 ,3年、5年生存率分别达到 41.7%、2 7.8% ,对多发性肝转移灶行微波固化也能获得较满意效果。结论　进展期乙状结肠癌 ,无肝硬化病例更易发生肝转移。大肠癌根治加肝转移灶切除加门静脉和区域动脉插管化疗是较理想的治疗方法     

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。     

结直肠癌同时性肝转移治疗46例分析

目的:探讨结直肠癌同时性肝转移的有效治疗方法。方法:对1996～2004年收治的46例结直肠癌同时性肝转移的临床资料和随访资料进行回顾性分析。根据治疗方法的不同分为3组:A组21例,为一期切除原发灶和肝转移灶并经肝动脉和门静脉置泵化疗者;B组15例,为单纯原发灶切除并经肝动脉和门静脉置泵化疗者;C组10例,为原发灶和肝转移灶均未能切除而仅行肝动脉和门静脉置泵化疗者。用KaplanMeier法对病人的生存时间作统计分析。结果:A、B、C3组术后中位生存期分别为38、20和13个月;各组之间术后生存时间的比较均有显著统计学差异(P<0.01)。结论:结直肠癌原发灶和肝转移灶一期手术切除并经肝动脉和门静脉置泵化疗的疗效最好;肝转移灶无法切除者能将原发灶切除并经肝动脉和门静脉置泵化疗也可取得较好的疗效;原发灶和肝转移灶未能切除而仅经肝动脉和门静脉置泵化疗的疗效相对较差。对结直肠癌同时性肝转移应采取以手术切除为主的综合措施进行积极治疗。     

Selection criteria for simultaneous resection in patients with synchronous liver metastasis

HYPOTHESIS: While simultaneous resection has been shown to be safe and effective in patients with synchronous metastasis, neoadjuvant chemotherapy followed by hepatectomy has gradually gained acceptance for both initially nonresectable metastasis and resectable metastasis. The boundary between these treatments is becoming unclear. We hypothesized that factors associated with colorectal cancer may play an important role in the prognosis of patients with synchronous metastasis and may be useful for identifying patients who can be expected to have adequate results following simultaneous resection. DESIGN: Outcome study. SETTING: Tertiary referral center. PATIENTS: From January 1980 to December 2002, 187 patients underwent curative resection for synchronous liver metastasis from colorectal cancer. One hundred forty-two patients received simultaneous resection, 18 underwent staged resection, and 27 underwent delayed hepatic resection. Twenty-one clinicopathological factors were analyzed, and long-term prognosis was assessed. MAIN OUTCOME MEASURES: Prognostic factors and patient survival. RESULTS: There was no in-hospital death. In a multivariate analysis, the factors that significantly affected the prognosis of synchronous metastasis were 4 or more lymph node metastases around the primary cancer (P<.001) and multiple liver metastases (P = .003). In patients with 3 or fewer lymph node metastases around the primary cancer, the 5-year survival rates of those with 1, 2 to 3, and 4 or more liver metastases were 63%, 33%, and 40%, respectively, but these rates were 15%, 22%, and 0%, respectively, in patients with 4 or more lymph node metastases around the primary cancer. CONCLUSIONS: The results support the application of simultaneous resection in patients with 0 to 3 colorectal lymph node metastases. However, in patients with 4 or more colorectal lymph node metastases, biological selection by neoadjuvant chemotherapy may be more suitable.     

结直肠癌肝转移综合治疗体会

目的总结分析综合疗法控制结直肠癌肝转移的效果和体会。方法回顾性分析1996．1-2004．12结直肠癌肝转移106例临床资料。结果术前发现肝转移者行同期肝转移灶切除16例，门静脉化疗泵植入5例；术后发现肝转移灶者85例行手术切除、全身化疗、射频消融（PRFA）、无水酒精注射（PEI）、经导管肝动脉化疗栓塞（TACE）等综合治疗。无手术死亡。治疗后CEA转阴29．2％，下降56．9％。随访率92．5％，随访期8个月至5年。缓解率（CR＋PR）为92．9％。病人1，3，5年生存率分别为96．9％、51．8％和23．2％。结论积极手术切除，配合局部消融和全身化疗的综合治疗是控制结直肠癌肝转移的有效方案。     

Simultaneous laparoscopic resection of colorectal cancer and synchronous metastatic liver tumor

Laparoscopic colorectal resection has been applied to advanced colorectal cancer. Synchronous liver metastasis of colorectal cancer would be treated safely and effectively by simultaneous laparoscopic colorectal and hepatic resection. Seven patients with colorectal cancer and synchronous liver metastasis treated by simultaneous laparoscopic resection were analyzed retrospectively. Three patients received a hybrid operation using a small skin incision, 2 patients underwent hand-assisted laparoscopic surgery using a small incision produced for colonic anastomosis, and 2 patients were treated with pure laparoscopic resection. The mean total operation duration was 407 minutes, and mean blood loss was 207 mL. Negative surgical margins were achieved in all cases. Mean postoperative hospital stay was 16.4 days. No recurrence at the surgical margin was observed in the liver. For selected patients with synchronous liver metastasis of colorectal cancer, simultaneous laparoscopic resection is useful for minimizing operative invasiveness while maintaining safety and curability, with satisfying short- and long-term results.

Simultaneous liver and colorectal resections are safe for synchronous colorectal liver metastasis

BACKGROUND: The optimal surgical strategy for the treatment of synchronous resectable colorectal liver metastasis has not been defined. The aims of this study were to review our experience with synchronous colorectal metastasis and to define the safety of simultaneous versus staged resection of the colon and liver. STUDY DESIGN: From September 1984 through November 2001, 240 patients were treated surgically for primary adenocarcinoma of the large bowel and synchronous hepatic metastasis. Clinicopathologic, operative, and perioperative data were reviewed to evaluate selection criteria, operative methods, and perioperative outcomes. RESULTS: One hundred thirty-four patients underwent simultaneous resection of a colorectal primary and hepatic metastasis in a single operation (Group I), and 106 patients underwent staged operations (Group II). Simultaneous resections tend to be performed for right colon primaries (p < 0.001), smaller (p < 0.01) and fewer (p < 0.001) liver metastases, and less extensive liver resection (p < 0.001). Complications were less common in the simultaneous resection group, with 65 patients (49%) sustaining 142 complications, compared with 71 patients (67%) sustaining 197 complications for both hospitalizations in the staged resection group (p < 0.003). Patients having simultaneous resection required fewer days in the hospital (median 10 days versus 18 days, p = 0.001). Perioperative mortality was similar (simultaneous, n = 3; staged, n = 3). CONCLUSIONS: Simultaneous colon and liver resection is safe and efficient in the treatment of patients with colorectal cancer and synchronous liver metastasis. By avoiding a second laparotomy, the overall complication rate is reduced, with no change in operative mortality. Given its reduced morbidity, shorter treatment time, and similar cancer outcomes, simultaneous resection should be considered a safe option in patients with resectable synchronous colorectal metastasis.     

Laparoscopic resection of colon cancer and synchronous liver metastasis

The recommended surgical approach to synchronous colorectal metastasis has not been clarified. Simultaneous open liver and colon resection for synchronous colorectal carcinoma has been shown beneficial when compared to staged resections. A review of the literature has shown the benefits of both laparoscopic colon resection for colorectal cancer and laparoscopic left lateral segmentectomy in liver disease. We present the case of a 60-year-old male with sigmoid colon carcinoma and a synchronous solitary liver metastasis localized to the left lateral segment. Using laparoscopic techniques, we were able to achieve simultaneous resection of the sigmoid colon and left lateral liver segment.     

结直肠癌伴同时性肝转移的治疗

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.     

Surgical treatment of liver metastases from colorectal cancer

We analyze our experience over a 10-year period in the surgical treatment of liver metastases from colorectal cancer. Between 01.01.1995 and 08.31.2005 189 liver resections were performed in 171 patients with liver metastases from colorectal cancer (16 re-resections - 2 in the same patient and a "two-stage" liver resection in 2 patients). In our series there were 83 patients with synchronous liver metastases (69 simultaneous resections, 12 delayed resections and 2 "two-stage" liver resection were performed) and 88 metachronous liver metastases. Almost all types of liver resections have been performed. The morbidity and mortality rates were 17.4% and 4.7%, respectively. Median survival was 28.5 months and actuarial survival at 1-, 3- and 5-year was 78.7%, 40.4% and 32.7%, respectively. Between January 2002 and August 2005 hyperthermic ablation of colorectal cancer liver metastases has been performed in 6 patients; in other 5 patients with multiple bilobar liver metastases liver resection was associated with radiofrequency ablation and one patient underwent only radiofrequency ablation for recurrent liver metastasis. In conclusion, although the treatment of colorectal cancer liver metastases is multimodal (resection, ablation, chemotherapy and radiation therapy), liver resection is the only potential curative treatment. The quality and volume of remnant liver parenchyma is the only limitation of liver resection. The morbidity, mortality and survival rates after simultaneous liver and colorectal resection are similar with those achieved by delayed resection. Postoperative outcome of patients with major hepatic resection is correlated with the surgical team experience. The long-term survival was increased using the new multimodal treatment schemes.     

结直肠癌同时性肝转移同期与分期手术切除疗效比较

目的：比较结直肠癌同时性肝转移患者原发灶和肝转移灶同期与分期切除的近期和远期结局。方法回顾性分析北京肿瘤医院肝胆胰外一科2003年1月至2011年12月间的64例结直肠癌合并同时性肝转移患者的临床及术后随访资料,其中行原发灶和肝转移灶同期切除者20例（同期切除组）,分期切除者44例（分期切除组）。结果同期切除组Clavien-Dindo 1、2和3级并发症发生率分别为10．0％（2/20）、15．0％（3/20）和15．0％（3/20）,分期切除组分别为13．6％（6/44）、13．6％（6/44）和22．7％（12/44）,差异无统计学意义（P＞0．05）。同期切除组1、2和3年总体生存率分别为85．0％、59．6％和37．2％,分期切除组分别为90．9％、68．2％和47．1％,差异亦无统计学意义（均P＞0．05）。两组中位无病生存时间分别为6月和7月,差异亦无统计学意义（P＞0．05）。多因素预后分析显示,原发灶淋巴结阳性（P=0．020）和肝切除术前CEA水平大于20μg/L（P=0.017）是影响患者总体生存的独立危险因素;复发后有机会接受根治性局部治疗联合化疗则是一项保护性因素（P=0.001）;而手术时机（同期或分期切除）与患者总体生存无关（P＞0．05）。结论对于结直肠癌同时性肝转移,选择同期或分期切除并不影响患者的术后并发症发生率和远期生存率。
