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.  相似文献

Background This study evaluated our 7-year experience treating unresectable colorectal cancer (CRC) hepatic metastases refractory to systemic 5-fluorouracil. Methods A total of 185 patients with unresectable 5-fluorouracil-resistant CRC hepatic metastases underwent surgical cytoreduction. Postoperatively patients received either hepatic arterial floxuridine (FUDR) and systemic irinotecan as part of a phase II trial or no further treatment. Results Of the 185 patients undergoing surgical cytoreduction. 71 patients received adjuvant irinotecan/FUDR. There were no appreciable differences in synchronous or metachronous lesions or the median number or size of lesions between treatment groups. At a median follow-up of 20 months, there were fewer recurrences in patients treated with postoperative irinotecan/FUDR compared with untreated patients for both hepatic and extrahepatic recurrences. Progression-free and overall survival were longer for patients who received irinotecan/FUDR compared with patients who did not receive adjuvant therapy. The 2-year survival rate was significantly better for patients receiving adjuvant therapy compared with patients receiving no additional treatment. Predictors of improved survival included a preoperative carcinoembryonic antigen level <100 ng/dl, >30% postoperative reduction in carcinoembryonic antigen level, and adjuvant therapy. Conclusions Combined therapy with irinotecan/FUDR may improve the results of surgical cytoreduction for unresectable CRC hepatic metastases.

Background We have previously shown promising activity of hepatic arterial infusion (HAI) oxaliplatin combined with intravenous (IV) 5-fluorouracil (5-FU) and leucovorin (LV) as first-line chemotherapy in patients with colorectal liver metastases (CRLM) (intent-to-treat [ITT] objective response rate [ORR], 64%; secondary resection rate, 18%; overall survival [OS], 27 months). Whether this regimen could be beneficial after systemic chemotherapy failure is unknown. Methods Patients with unresectable CRLM and history of systemic chemotherapy failure were treated bimonthly with HAI oxaliplatin (100 mg/m2 2 hours) combined with IV LV and IV bolus and infusional 5FU (modified LV5FU2 regimen). Results Forty-four consecutive patients (median age 56 years; median number of prior systemic chemotherapy regimens, 2 range 1–5) were included, of whom 43 (98%) had previously received oxaliplatin (n = 34), irinotecan (n = 37), or both (n = 28). Patients received a median of nine cycles of HAI oxaliplatin and IV modified LV5FU2 (range 0–25). Toxicity included grade 3–4 neutropenia (43%), grade 2–3 neuropathy (43%), and grade 3–4 abdominal pain (14%). We observed 24 partial ORs (62%) among the 39 assessable patients (ITT ORR, 55%; 95% CI, 40–69%), including 17, 12, and 12 patients who had failed to respond to prior systemic chemotherapy with FOLFIRI, FOLFOX, or both, respectively. Tumor response allowed further R0 surgical resection (n = 7) or radiofrequency ablation (n = 1) of initially unresectable CRLM in eight patients (18%). Median progression-free survival and OS were 7 and 16 months, respectively. Conclusions HAI oxaliplatin and IV LV5FU2 is feasible, safe, and shows promising activity after systemic chemotherapy failure, allowing surgical resection of initially unresectable CRLM in 18% of patients.  相似文献

OBJECTIVE: To analyze the effects of 5-fluorouracil (5-FU) chemotherapy combined with preoperative irradiation and the role of intraoperative electron beam irradiation (IOERT) on the outcome of patients with primary locally advanced rectal or rectosigmoid cancer. METHODS: From 1978 to 1996, 145 patients with locally advanced rectal cancer underwent moderate- to high-dose preoperative irradiation followed by surgical resection. Ninety-three patients received 5-FU as a bolus for 3 days during the first and last weeks of radiation therapy (84 patients) or as a continuous infusion throughout irradiation (9 patients). At surgery, IOERT was administered to the surgical bed of 73 patients with persistent tumor adherence or residual disease in the pelvis. RESULTS: No differences in sphincter preservation, pathologic downstaging, or resectability rates were observed by 5-FU use. However, there were statistically significant improvements in 5-year actuarial local control and disease-specific survival in patients receiving 5-FU during irradiation compared with patients undergoing irradiation without 5-FU. For the 73 patients selected to receive IOERT, local control and disease-specific survival correlated with resection extent. For the 45 patients undergoing complete resection and IOERT, the 5-year actuarial local control and disease-specific survival were 89% and 63%, respectively. These figures were 65% and 32%, respectively, for the 28 patients undergoing IOERT for residual disease. The overall 5-year actuarial complication rate was 11%. CONCLUSIONS: Treatment strategies using 5-FU during irradiation and IOERT for patients with locally advanced rectal cancer are beneficial and well tolerated.  相似文献

BACKGROUND: Treatment of metastatic colorectal cancer to the liver is not uniform. We describe the management of metastatic colorectal cancer of the liver at a single institution during a 10-year period. METHODS: From January 1, 1990, through December 31, 1999, 174 patients were identified from the tumor registry at the University of Alabama at Birmingham with a diagnosis of metastatic colorectal cancer to the liver. Patient, tumor, laboratory, operative, and adjuvant therapy factors were analyzed, with overall survival as the endpoint. Log-rank tests were used for univariate analysis, Cox-proportional hazards model for multivariate analysis, and Kaplan-Meier curves were used for graphical representation of survival. Significance was defined as P<.05. RESULTS: Median age was 60 years (age range, 18-92 years). Seventy-nine percent of patients had synchronous liver metastases at the time of diagnosis of the primary colorectal tumor. The primary tumor was in the colon and rectum 75% and 25% of the time, respectively. Of the 89 patients who underwent operation, 73 received definitive surgical treatment for their liver metastases. Fifty-two patients underwent lobectomy or wedge resection, 5 underwent cryotherapy, and 16 had a hepatic artery infusion pump (HAIP) inserted. Median follow-up duration of surgically treated patients was 26 months. Operative mortality was 1.3%. The 3-year actuarial survivals for patients who underwent resection, HAIP, or those with unresectable disease were 70 months, 32 months, and 3 months, respectively (P<.001). By multivariate analysis, surgical intervention, a carcinoembryonic antigen level less than 200 microg/L, or a low T stage of the primary tumor were associated with prolongation of survival. CONCLUSIONS: Surgical resection should be attempted for hepatic colorectal metastases, as this is associated with prolonged overall survival. Hepatic artery infusion pump insertion seems to prolong overall survival for those with unresectable hepatic metastases, but it is not equal to resection. Aggressive surgical management of patients with hepatic colorectal metastases is safe, may prolong overall survival, and therefore should be considered in all patients with metastases confined to the liver.  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

OBJECTIVE: To determine the impact of adjuvant hepatic arterial infusion (HAI) on survival relative to resection alone in patients with radical resection of colorectal liver metastases. SUMMARY BACKGROUND DATA: Nearly 40% to 50% of all patients with colorectal carcinoma develop liver metastases. Curative resection results in a 5-year survival rate of 25% to 30%. Intrahepatic recurrence occurs after a median of 9 to 12 months in up to 60% of patients. The authors hypothesized that adjuvant intraarterial infusion of 5-fluorouracil (5-FU) might decrease the rate of intrahepatic recurrence and improve survival in patients with radical resection of colorectal liver metastases. METHODS: Between April 5, 1991, and December 31, 1996, patients with colorectal liver metastases from 26 hospitals were stratified by the number of metastases and the site of the primary tumor and randomized to resection of the liver metastases followed by adjuvant HAI of 5-FU (1000 mg/m2 per day for 5 days as a continuous 24-hour infusion) plus folinic acid (200 mg/m2 per day for 5 days as a short infusion), or liver resection only. RESULTS: The first planned intention-to-treat interim analysis after inclusion of 226 patients and 91 events (deaths) showed a median survival of 34.5 months for patients with adjuvant therapy versus 40.8 months for control patients. The median time to progression was 14.2 months for the chemotherapy group versus 13.7 months for the control group. Grade 3 and 4 toxicities (World Health Organization), mainly stomatitis (57.6%) and nausea (55.4%), occurred in 25.6% of cycles and 62.9% of patients. CONCLUSION: According to this planned interim analysis, adjuvant HAI, when used in this dose and schedule in patients with resection of colorectal liver metastases, reduced the risk of death at best by 15%, but at worst the risk of death was doubled. Thus, the chance of detecting an expected 50% improvement in survival by the use of HAI was only 5%. Patient accrual was therefore terminated.  相似文献

OBJECTIVE: We reported here a series of 49 patients with unresectable hepatocellular carcinoma (HCC) who underwent nonsurgical treatment to downstage the disease followed by salvage surgery, their long-term outcome, and pattern of recurrence. SUMMARY BACKGROUND DATA: Most HCC patients present with unresectable disease and are treated with chemotherapy or intra-arterial therapy with a palliative intent. Occasionally, there are good responses to treatment so that salvage surgery becomes feasible afterward. However, long-term outcomes of these patients are seldom reported. METHODS: Patients with unresectable hepatocellular carcinoma, from September 1993 to June 2002, who received salvage surgery after downstaging by systemic chemotherapy, intra-arterial yttrium-90 microspheres, or sequential treatment were included in this study. Systemic chemotherapy consisted of combination doxorubicin, cisplatin, interferon-alpha and 5-fluorouracil (5-FU), or single-agent doxorubicin. The choice of treatment was according to stage of disease and contemporary clinical trial protocol. Survival, recurrence pattern, and surgical outcome were studied. RESULTS: There were 49 patients in this study with 40 males and 9 females, age ranged from 12 to 69 years. Forty patients (81.6%) were hepatitis B positive. Thirty-two patients had combination chemotherapy alone (65.3%), 8 patients had single agent chemotherapy alone (16.3%), 4 patients received intra-arterial yttrium-90 microspheres alone (8.2%), and 5 patients received sequential therapy (10.2%). Twenty-eight (57.1%) patients received major hepatic resection. Thirteen patients (26.5%) had complete necrosis of the tumor after treatment. Twenty-one patients (42.9%) had recurrence after surgery, and 14 of them were intrahepatic recurrence. The median survival was 85.9 months. The 1-year, 3-year, and 5-year survival rates were 98%, 64%, and 57%, respectively. CONCLUSIONS: Salvage surgery after successful downstaging can provide long-term control of disease in a small proportion of patients with unresectable hepatocellular carcinoma.  相似文献

With advances in surgical techniques, the number of curative resection for hilar cholangiocarcinoma has increased. However, the recurrence rate after curative resection is significantly high. There is no established adjuvant therapy for these patients, although some groups have administered intraarterial infusion of 5-fluorouracil combined with cisplatin. In our institution, postoperative radiation is administered to control remnant tumors at the ductal and surgical margins. Extracorporeal radiation is directed at the surgical margins and intraluminal radiation at the ductal margins. This has improved the cumulative survival rate for cholangiocarcinoma patients who underwent both curative and noncurative resection. The 3-year survival rate of those who underwent curative resection with and without postoperative radiation is 100% and 28.5%, respectively. The longest survival duration among our patients who received intraluminal radiation for positive ductal margins were 55 months. Because the biological behaviour and radiation sensitivity of the tumors differ among individually, these should be determined through molecular biologic studies in the future. Such tailored therapy will require multidisciplinary treatment.  相似文献

Approximately 50%–60% of patients with colorectal cancers will develop liver lesions in their life span. Despite the potential of surgical resection to provide long-term survival in this subset of patients, only 15%–20% are found to be resectable. The introduction of new neoadjuvant chemotherapeutic agents and the expanding criteria of resection have enhanced the overall 5-year survival from 30% to 60% in the past decade. The use of technical innovations such as staged resection; portal vein embolization, and repeat resection have allowed higher resection rates in patients with bilobar disease. Extrahepatic primary and liver-exclusive recurrent disease no longer represent an absolute contraindication to resection. The role of regional therapy using hepatic arterial infusion is being redefined for liver-exclusive unresectable disease. Adjuvant chemotherapy in combination with regional therapies is being looked at from fresh perspectives. Ablative approaches have gained a firm role both as an adjunct to surgical resection and in the management of patients who are not surgical candidates. Overall, the management of hepatic metastasis from colorectal cancers requires a multimodal approach.  相似文献

Background The outcome after resection of advanced pancreatic cancers is extremely poor because of the high incidence of the postoperative development of liver metastasis and local recurrence. We performed a combination of chemoradiation and liver perfusion chemotherapy and extended pancreatectomy.Methods Nineteen patients with T3 pancreatic head cancers were enrolled. A total of 24 Gy in 12 fractions of 10-MV x-rays with a concurrent intravenous infusion of 5-fluorouracil (5-FU; 3 g/12 days) was administered to the pancreatic head area. An extended pancreaticoduodenectomy was performed, and catheters were placed into the gastroduodenal artery and the superior mesenteric vein. During the first 28 postoperative days, 5-FU was continuously infused via the hepatic artery and portal vein (3.5 g/28 days × 2). Finally, 36 Gy in 18 fractions with 5-FU (3 g/6 days) was applied to the pancreatic bed.Results After preoperative chemoradiation, four patients did not undergo surgical resection because of distant metastases. Fifteen patients underwent pancreaticoduodenectomy, liver perfusion chemotherapy, and postoperative chemoradiation. No patient developed grade 3 toxicity as a result of preoperative chemoradiation, but one patient (7%) developed grade 3 leukopenia during the postoperative treatments. The morbidity rate was 20% (3 of 15 patients), and the mortality rate was 0%. The overall 3-year survival rate was 53%. The 3-year disease-free survival rate was 66% in patients who pathologically responded well (>50%), versus 0% in patients with poor responses (P = .04).Conclusions A combination of preoperative and postoperative chemoradiation plus postoperative liver perfusion chemotherapy with an extended pancreatectomy is feasible, and the long-term outcomes are also promising.  相似文献

An eleven-year experience with adrenocortical carcinoma.   总被引:7,自引:0,他引:7  
R F Pommier  M F Brennan 《Surgery》1992,112(6):963-70; discussion 970-1
BACKGROUND. Key issues in the treatment of adrenocortical carcinoma are the value of adjuvant therapy, the value of reoperation, and the search for effective chemotherapeutic agents. The present series was reviewed to evaluate these issues. METHODS. We present a retrospective series of 73 patients with adrenocortical carcinoma treated at a single institution. RESULTS. Twenty patients had carcinomas that were unresectable, and 53 patients underwent complete resections. Ten patients received adjuvant therapy (mitotane, seven patients; radiation, three patients). Forty-five (85%) patients had recurrence, including all who received adjuvant therapy. Mean disease-free intervals for those who did and did not receive adjuvant therapy were equivalent at 2.4 years. Nineteen patients with recurrent disease received chemotherapy, and 26 patients underwent 51 reoperations to resect recurrent and metastatic disease. The overall 5-year survival rate, which was 35%, was 47% for patients with complete resection. Stage and resectability were prognostic factors. Mean survival time for patients with recurrent disease treated medically was 19 months compared with 56 months for patients who underwent reoperation. Mitotane had a 24% partial response rate. Other chemotherapeutic agents were ineffective. CONCLUSIONS. We conclude that an aggressive surgical approach to recurrent and metastatic disease should be adopted and that patients should be resected free of disease whenever possible. Currently no effective chemotherapy exists, and the value of adjuvant therapy remains unproved.  相似文献

BACKGROUND/PURPOSE: Complete surgical resection after chemotherapy is the definitive treatment for hepatoblastoma. However, orthotopic liver transplantation (OLT) is now accepted as a treatment modality for patients with unresectable tumours. The aim of this study was to review a single center's experience of OLT for unresectable hepatoblastoma. METHODS: A retrospective review of 8 patients with unresectable hepatoblastoma who were referred for liver transplantation was conducted. RESULTS: The patients assessed had an age range of 5 to 105 months at presentation; median, 24 months, (5 boys; 3 girls). Two patients have familial adenomatous polyposis, and one has right hemihypertrophy. All 8 patients had received standard chemotherapy according to SIOP (International Society of Pediatric Oncology) protocols. Extrahepatic metastases were found in 3 patients at diagnosis, but none had detectable metastases at the time of OLT. Four patients continued chemotherapy while awaiting OLT. Three patients received whole grafts, and 5 received reduced grafts. The median follow-up period was 22 months (range, 2 to 78 months). Five patients are alive and well, although 1 patient had a second OLT for biliary cirrhosis secondary to biliary stricture at 6 years. Three patients died: one 26 days post OLT of sepsis and two of disease recurrence at 22 months and 70 months posttransplant. The actuarial survival rate is 88% and 65% at 1 and 5 years, respectively, whereas the overall survival rate is 62.5%. CONCLUSION: OLT for unresectable hepatoblastoma without extra hepatic metastases is highly successful with a low recurrence rate.  相似文献

Combined portal vein and liver resection for carcinoma of the biliary tract   总被引:14,自引:0,他引:14  
Twenty-nine patients with advanced carcinoma of the bile duct or gallbladder underwent combined portal vein and liver resection. Segmental excision of the portal vein was performed in 16 cases and wedge resection of the vessel wall in 13. The operative mortality rate was 17 per cent. The median survival for the 24 patients who left hospital was 19.8 months. Actuarial survival rates at 1, 3 and 5 years for all 29 patients were 48 per cent, 29 per cent, and 6 per cent respectively, whereas the median survival for 46 patients with unresectable carcinoma was 3 months and the 1 and 3-year actuarial survival rates were 13 per cent and zero respectively. This difference in survival times between patients undergoing hepatectomy with portal vein resection and those with unresectable carcinoma were statistically significant (P less than 0.01). Combined portal vein and liver resection is recommended as a reasonable surgical approach in selected patients with advanced carcinoma of the biliary tract.  相似文献

OBJECTIVE: To evaluate the results of a prospective multicenter randomized study of adjuvant intraperitoneal 5-fluorouracil (5-FU) administered during 6 days shortly after resection of stages II and III colon cancers. SUMMARY BACKGROUND DATA: Systemic adjuvant chemotherapy improves the survival of patients with stage III colon cancer receiving treatment for 6 months. Intraperitoneal chemotherapy theoretically combines peritoneal and hepatic effects. METHODS: After resection, 267 patients were randomized into two groups. Patients in group 1 (n = 133) underwent resection followed by intraperitoneal administration of 5-FU (0.6 g/m2/day) for 6 days (day 4 to day 10). These patients also received intravenous 5-FU (1 g) during surgery. Patients in group 2 underwent resection alone (n = 134). RESULTS: In group 1, 103 patients received the total dose, 18 received a partial dose as a result of technical or tolerance problems, and 12 did not receive the chemotherapy. Rates of surgical death and complications were similar in both groups. Tolerance to treatment was excellent or fair in 97% of the patients and poor in 3%. After a median follow-up of 58 months, 5-year overall survival rates were 74% in group 1 and 69% in group 2; disease-free survival rates were 68% and 62%, respectively. Survival curves were superimposed until 3 years after treatment and began diverging thereafter. Among patients receiving the full treatment, the 5-year disease-free survival rate was improved in the treatment group in patients with stage II cancers but was unchanged in patients with stage III cancers. CONCLUSIONS: Chemotherapy with intraperitoneal 5-FU administered during a short period after surgery was well tolerated but was not sufficient to reduce the risk of death significantly. However, it reduced the risk of recurrence in stage II cancers. These results suggest that it should be associated with systemic chemotherapy to reduce both local and distant recurrences.  相似文献
