结直肠癌肝转移一期联合手术化疗的临床研究 总被引:1,自引:0,他引:1
目的探讨结直肠癌肝转移一期联合手术辅助化疗的有效途径及临床价值.方法回顾性分析一期联合手术切除原发癌及转移癌,经肝动脉门静脉双置泵栓塞灌注化疗,肿瘤局部注射无水酒精及热电疗法综合性治疗结直肠癌肝转移36例的临床资料.结果本组36例结直肠癌患者原发癌均获切除,其中一期切除肝转移癌17例,6例复发,4例再次手术切除.19例不能切除的转移性肝癌,行肝动脉门静脉双置泵栓塞灌注化疗,无水酒精注射和热电疗法.肿瘤直径平均缩小57%,其中4例因肿瘤缩小行二期手术切除.1、2、3年生存率分别为切除组94%,82%,65%;明显高于置泵组的74%,53%,32%(P<0.01).结论结直肠癌肝转移一期联合手术切除加肝动脉门静脉双置泵栓塞灌注化疗,是一种首选而有效的治疗方法.不能切除肝转移癌者,只要切除原发肿瘤,肝动脉门静脉置泵栓塞灌注化疗,可明显延长病人生存期,改善预后. 相似文献

结直肠癌同时性肝转移治疗46例分析 总被引:1,自引:0,他引:1
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。 相似文献

对结直肠癌肝转移来说,手术是惟一的治愈手段。但80%的病人初始是不可切除的,将不可切除肝转移转化为可切除是提高结直肠癌总体存活率的关键。目前常用的转化手段有全身化疗(包括单纯化疗、化疗联合靶向药物等)、肝动脉灌注(HAI)、射频消融(RFA)、联合门静脉结扎或栓塞的分期肝切除、联合肝脏分隔及门静脉结扎的二步肝切除等。了解各种转化治疗的有效率和适应证是选择合适治疗的前提。 相似文献

Prophylactic portal infusion chemotherapy as adjuvant therapy for the prevention of metachronous liver metastasis in colorectal cancer 总被引:1,自引:0,他引:1
Osamu Kimura Kazuo Kurayoshi Kazuyoshi Hoshino Akira Sugezawa Masato Makino Nobuaki Kaibara 《Surgery today》1995,25(3):211-216
The DNA ploidy and DNA indices (DI) of 414 patients with colorectal cancer were analyzed, and the incidence of patients with metachronous liver metastasis was found to be significantly higher in those with aneuploid tumors and a DI above 1.5 than in those with aneuploid tumors and a DI below 1.4, or in those with diploid tumors and a DI equal to 1.0. Next, to confirm the effectiveness of administering prophylactic portal infusion chemotherapy (PPIC) as adjuvant therapy for the prevention of metachronous liver metastasis in colorectal cancer, a randomized controlled trial of PPIC was performed on 110 consecutive patients with primary colorectal cancer who had undergone curative resection. Although the incidence of patients with metachronous liver metastasis in the two study groups was not significantly different at 3.3% in the PPIC group and 10.3% in the control group, the incidence in the patients with aneuploidy and a DI above 1.5 was significantly lower in the PPIC group than in the control group. These findings suggest that colorectal cancer with aneuploidy and a DI above 1.5 may have a strong tendency to metastasize to the liver, and that prophylactic portal infusion chemotherapy may be effective for preventing metachronous liver metastasis in such patients. 相似文献

Colorectal cancer is the fourth most common type of cancer in the West and the second leading cause of cancer-related deaths
in the United States. Approximately 35 to 55% of patients with colorectal cancer develop hepatic metastases during the course
of their disease. Surgical resection of colorectal liver metastases represents the only chance at potential cure, and long-term
survival can be achieved in 35 to 58% of patients after resection. The goal of hepatic resection should be to resect all metastases
with negative histologic margins while preserving sufficient functional hepatic parenchyma. In patients with extensive metastatic
disease who would otherwise be unresectable, ablative approaches can be used instead of or combined with hepatic resection.
The use of portal vein embolization and preoperative chemotherapy may also expand the population of patients who are candidates
for surgical treatment. Despite these advances, many patients still experience a recurrence after hepatic resection. More
active systemic chemotherapy agents are now available and are being increasingly employed as adjuvant therapy either before
or after surgery. Modern treatment of colorectal liver metastasis requires a multidisciplinary approach in an effort to increase
the number of patients who may benefit from surgical treatment of colorectal cancer liver metastasis. 相似文献

OBJECTIVE: To examine recurrence and survival rates for patients treated with hepatic resection only, radiofrequency ablation (RFA) plus resection or RFA only for colorectal liver metastases. SUMMARY BACKGROUND DATA: Thermal destruction techniques, particularly RFA, have been rapidly accepted into surgical practice in the last 5 years. Long-term survival data following treatment of colorectal liver metastasis using RFA with or without hepatic resection are lacking. METHODS: Data from 358 consecutive patients with colorectal liver metastases treated for cure with hepatic resection +/- RFA and 70 patients found at laparotomy to have liver-only disease but not to be candidates for potentially curative treatment were compared (1992-2002). RESULTS: Of 418 patients treated, 190 (45%) underwent resection only, 101 RFA + resection (24%), 57 RFA only (14%), and 70 laparotomy with biopsy only or arterial infusion pump placement ("chemotherapy only," 17%). RFA was used in operative candidates who could not undergo complete resection of disease. Overall recurrence was most common after RFA (84% vs. 64% RFA + resection vs. 52% resection only, P < 0.001). Liver-only recurrence after RFA was fourfold the rate after resection (44% vs. 11% of patients, P < 0.001), and true local recurrence was most common after RFA (9% of patients vs. 5% RFA + resection vs. 2% resection only, P = 0.02). Overall survival rate was highest after resection (58% at 5 years); 4-year survival after resection, RFA + resection and RFA only were 65%, 36%, and 22%, respectively (P < 0.0001). Survival for "unresectable" patients treated with RFA + resection or RFA only was greater than chemotherapy only (P = 0.0017). CONCLUSIONS: Hepatic resection is the treatment of choice for colorectal liver metastases. RFA alone or in combination with resection for unresectable patients does not provide survival comparable to resection, and provides survival only slightly superior to nonsurgical treatment. 相似文献

转移性肝癌是恶性肿瘤发展的终末阶段,是导致患者死亡的主要原因,其中胃肠道是常见的原发癌部位。人们正尝试通过根治转移性肝癌或控制其发展等多种治疗策略,延长患者生存期。手术治疗、全身化疗、分子靶向治疗、射频消融术、门静脉栓塞术、肝动脉导管栓塞术是转移性肝癌的有效治疗方法,其中手术治疗是转移性肝癌可能获得治愈的有效手段。相比结肠癌肝转移癌,胃癌肝转移癌的治疗正处于探索阶段,但是随着新型有效化疗药物及化疗方案的出现、肝转移癌手术适应证的拓展以及大规模多中心临床试验循证医学证据的涌现,包括胃癌肝转移在内的转移性肝癌的治疗必将朝着一个更加规范,更为有效的方向发展。 相似文献
