Application of FLEEOX Preoperative Chemotherapy via Intra-arterial and Intravenous Administration in Treatment of Unresectable Locally Advanced Gastric Cancer

Background

The prognosis of unresectable locally advanced gastric cancer is poor. We applied preoperative chemotherapy via intra-arterial and intravenous administration to convert an initially unresectable gastric cancer to a resectable cancer.

Methods

From January 2005 to December 2010, 105 patients with unresectable locally advanced gastric cancer (T3-4N1-3M0) were selected for preoperative chemotherapy with 5-FU + leucovorin + etoposide + oxaliplatin + epirubicin (FLEEOX) regimen. 5-Fu (370 mg/m²) and leucovorin (200 mg/m²) were administered by intravenous infusion on days 1–5. Intra-arterial administration of etoposide (80 mg/m²), oxaliplatin (80 mg/m²), and epirubicin (30 mg/m²) was performed by Seldinger method on days 6 and 20, repeated two cycles. Patients who achieved partial response (PR) or complete response (CR) underwent D2 dissection, followed by four to six cycles of XELOX chemotherapy. The response rate, 1- and 3-year survival rate, and R0 resection rate were evaluated.

Results

The response rate of preoperative chemotherapy was 78.1 % (82 of 105 patients), with 7 cases of CR and 75 cases of PR, respectively. After chemotherapy, a total of 78 patients (74.3 %) underwent surgery, and 67 cases achieved R0 resection (85.9 %). The 1- and 3-year overall survival (OS) rate of all 105 patients was 71.9 and 31.7 % (median survival time, 18 months). The 1- and 3-year OS rate among the 78 patients treated with chemotherapy plus surgery was 84.5 and 40 % (median survival time, 30 months). Patients treated with chemotherapy plus surgery had significantly longer OS times than patients who underwent chemotherapy alone (P?<?0.01).

Conclusions

Patients with unresectable gastric cancer may obtain a survival benefit from preoperative chemotherapy via intra-arterial and intravenous administration and subsequent surgery.

目的：探讨进展期胃癌患者术前用奥沙利铂（OXA）联合5-氟尿嘧啶（5-FU）行区域性动脉灌注化疗的临床效果。
方法：48例Ⅱ期以上胃癌患者,术前行区域性动脉灌注化疗（A组）,方案为OXA 130 mg/m+ 5-FU 750 mg/m,经股动脉插管行区域冲击化疗1次,8～12 d后接受手术。同期另48例相同临床分期的胃癌患者直接行手术治疗（B组）。两组术后均接受OXA /甲酰四氢叶酸钙/5- FU方案化疗6个周期,观察两组的毒副反应、手术并发症和临床疗效。
结果：A组有38例（79.2%）获得根治性切除;镜检32例（66.7%）出现组织病理学改变,如肿瘤组织坏死、淋巴细胞炎性浸润、癌细胞凋亡、以及间质水肿纤维组织增生等。B组有30例（62.5%）行根治性切除,根治切除率显著低于A组,两组间差异有统计学意义（P<0.05）,且B组病理检查未出现上述变化。A组术前化疗的毒性反应均限于Ⅰ～Ⅱ级;两组的术后并发症无统计学差异。A组患者的中位生存期为36.0个月;1,2,3年总生存率分别为79.2%,62.5%和52.1%。B组中位生存期为21.5个月;1,2,3年总生存率分别为66.7%,45.8%和35.4%。A,B组比较,2年和3年总生存率差异有统计学意义（P<0.05）。
结论：术前应用OXA/5-FU方案行区域性动脉灌注化疗可使肿瘤组织产生显著的组织病理学改变,有利于提高进展期胃癌根治性手术切除率及2,3年生存率。     

Neoadjuvant Chemotherapy With P-ELF (Cisplatin, Etoposide, Leucovorin, 5-Fluorouracil) Followed by Radical Resection in Patients With Initially Unresectable Gastric Adenocarcinoma: A Phase II Study

Background: Gastric cancer is the most frequent gastrointestinal cancer in Mexico. Only 33% of cases are resectable. Our aim was to determine the activity and toxicity of the cisplatin, etoposide, leucovorin, and 5-fluorouracil combination in initially unresectable tumors and to determine its ability to permit resection.Methods: Sixty patients with unresectable gastric adenocarcinoma were treated with cisplatin 80 mg/m2, etoposide 80 mg/m2, leucovorin 25 mg/m2, and 5-fluorouracil 800 mg/m2 by central intravenous catheter for 4 consecutive days. Two courses of this combination were followed by surgical resection.Results: The overall response rate was 36.8% (20 partial responses and one complete response). By using logistic regression analysis, the tumor, node, and metastasis stage (risk ratio, 2.04; 95% confidence interval, 1.03–4.02; P 5.039) was identified as the response determinant to chemotherapy. Major toxicity was grade 3 or 4 neutropenia in 67% of patients. Ten resections were performed (17.5%); five were curative and five palliative. Operative morbidity and mortality rates were 40% and 10%, respectively. The median length of survival was 7.46 and 13.3 months for nonresponders and responders, respectively (P 5.011).Conclusions: The cisplatin, etoposide, leucovorin, and 5-fluorouracil combination is active in advanced gastric cancer and the toxicity level is acceptable. This treatment permits a 17.5% resection rate in previously unresectable tumors. A randomized trial of surgery vs. neoadjuvant chemotherapy plus surgery is warranted.     

胃癌术后辅助化疗两药和三药方案的选择

目的观察性研究胃癌术后辅助化疗中的两药方案（氟尿嘧啶联合铂类）与三药方案（在两药基础上联合蒽环类）对患者预后的影响。方法回顾性分析2004-2008年在上海复旦大学附属中山医院接受上述两药或三药方案进行术后辅助化疗的胃癌患者的临床资料和随访资料．随访终点为死亡或最终随访日（2010年4月30日）。结果共计316例接受过胃癌根治性手术且无远处转移的患者术后4-6周开始接受辅助化疗．化疗方案的选择根据主治医师和患者双方的讨论后决定。两药组210例,三药组106例。其中三药组较两药组年龄略轻（51岁比57岁．P〈0．01）,余基线情况两组间差异无统计学意义（P〉0．05）。中位随访时间47个月．两药组中位无进展生存期16个月,3年总体生存率59．6％：三药组则分别为23个月和64．8％,两组差异无统计学意义（P=0．656和P=0．293）。严重不良反应发生率两药组21．9％（46／210）。三药组30．2％（32／106）。两组差异无统计学意义（P=0．107）。结论胃癌术后辅助化疗中的三药联合方案未显示优于两药方案。     

术前区域性动脉灌注联合化疗治疗进展期胃癌的初步报告

目的 探讨含紫杉醇脂质体(力朴素)的联合化疗方案行术前区域性动脉灌注治疗进展期胃癌的可行性.方法 84例临床诊断Ⅱ期以上进展期胃癌患者在手术前接受区域性动脉灌注化疗,方案为:5-氟尿嘧啶(5-FU)1.1 g/m2,顺铂60 mg/m2,力朴素135 mg/m2;10～14 d后接受手术(研究组).同期收治的78例Ⅱ期以上胃癌患者行常规手术治疗(对照组).观察新辅助化疗后肿瘤原发病灶的缓解情况、毒副反应,以及两组问的疗效差异.结果 对照手术组48例(61.5%)获得根治性切除,1年总生存率为74.3%.新辅助化疗组全部完成术前区域性动脉化疗,毒性作用主要为胃肠道反应和骨髓抑制,均属可控范围内(1～2级);其中66例(78.5%)获得根治性切除,较对照手术组提高17.0%(P=0.018);1年总生存率为80.9%,较对照手术组无显著提高(P=0.283).结论 针对进展期胃癌患者,术前以力朴素联合5-FU、顺铂的方案行动脉介入化疗是安全有效的,它能提高根治手术切除率,但两组近期疗效无显著差异,可能与病例数较少和随访时间有关,尚须继续深入研究.     

Randomized trial of adjuvant chemotherapy after curative resection for gastric cancer

BACKGROUND: The aim of the study was to evaluate the efficacy of adjuvant chemotherapy on survival after resection for gastric cancer. METHODS: Patients were enrolled if they underwent resection of gastric cancer but had lymph node or serosal involvement or both. Surgical resection was either total or partial gastrectomy according to the site of the tumor, and surgeons were allowed to perform either D1 or D2 gastrectomy. The subjects were random assigned in two treatment groups as follows: surgery alone as the control group, or surgery and adjuvant chemotherapy. Nine cycles of 5 days protocol every 4 weeks was proposed to the patients of the chemotherapy group. The protocol included a daily administration of 200 mg/m(2) of folinic acid, 5-fluorouracil (375 mg/m(2) during the first session increasing 25 mg by session until reaching 500 mg/m(2)) and CDDP 15 mg/m(2). Two hundred patients were required. Kaplan-Meier survival curves were compared according to the log-rank and the Mantel-Haenszel methods. RESULTS: In all, 205 patients were enrolled in the study; 104 had surgery alone and 101 had surgery and adjuvant chemotherapy. The patients' characteristics were similar except for the mean age, which was 4 years less in the control group. Because of toxicity, 54% of the patients stopped the protocol before the end of the nine courses, and 46% of the patients received the nine courses including 32% with a decreased dose and 14% with a full dose. The 5-year survival rate was 39% in the control group and 39% in the chemotherapy group. CONCLUSIONS: This protocol of adjuvant chemotherapy failed to improve the 5-year survival after resection for gastric cancer.

Surgical resection after radiochemotherapy in patients with unresectable adenocarcinoma of the pancreas

BACKGROUND: The use of chemoradiotherapy for pancreatic cancer has been advocated for its potential ability to downstage locally advanced tumors. This article reports our experience with chemoradiotherapy for patients with unresectable, locally advanced pancreatic cancer (superior mesenteric artery or celiac axis encasement). STUDY DESIGN: Since 1998, 61 patients with radiographically unresectable, pathologically confirmed pancreatic adenocarcinoma have received standard fractionation radiation therapy (total dose, 45 Gy at 1.8 Gy, 5 d/wk) with chemotherapy, which included a continuous infusion of fluorouracil (5-FU: 650 mg/m(2)/D1-D5 and D21-D25) and cisplatin (80 mg/m(2)/bolus D2 and D22). Patients with tumor response at restaging CT scan underwent surgical exploration to determine whether the tumor was resectable. RESULTS: Thirty-eight of 61 (62%) restaged patients demonstrated a disease progression. Twenty-three patients (38%) had an objective response, with, in all cases, persistence of arterial encasement. Twenty-three patients underwent exploratory operations after chemoradiotherapy, and 13 underwent standard Whipple resection. So 13 of 23 (56%) patients who had exploratory operation, or 23 of 61 (21%) patients, underwent surgical resection. With a median followup of 27 months, median survival for the resected patients was 28 months. Median survival was 11 months in the nonresponder group (n = 38) and 20 months in the group who received a palliative procedure (n = 10). CONCLUSIONS: Locally advanced, unresectable pancreatic adenocarcinoma may be downstaged by chemoradiotherapy to allow for surgical resection. Patients whose cancer becomes resectable have a median survival at least comparable with survival after resection for initially resectable pancreatic adenocarcinoma.
