Abstract
PURPOSE To evaluate the clinical outcomes of percutaneous radiofrequency (RF) ablation of colorectal cancer liver metastases (CLMs) that recur after hepatectomy. MATERIALS AND METHODS From December 2002 to December 2008, 71 CLMs that developed after hepatectomy were ablated in 56 patients. Medical records and imaging were reviewed to determine technique effectiveness/complete ablation (ie, ablation defect covering the entire tumor on 4-6-week postablation computed tomography [CT]), complications, and local tumor progression (LTP) at the site of ablation. LTP-free and overall survival were calculated by using Kaplan-Meier methodology. A modified clinical risk score (CRS) including nodal status of the primary tumor, time interval between diagnoses of the primary tumor and liver metastases, number of tumors, and size of the largest tumor was assessed for its effect on overall survival and LTP. RESULTS Tumor size ranged between 0.5 and 5.7 cm. Complete ablation was documented in 67 of 71 cases (94%). Complications included liver abscess (n = 1) and pleural effusion (n = 1). Median overall survival time was 31 months. One-, 2- and 3-year overall survival rates were 91%, 66%, and 41%, respectively. CRS was an independent factor for overall survival (74% for CRS of 0-2 vs 42% for CRS of 3-4 at 2 y; P = .03) and for LTP-free survival (66% for CRS of 0-2 vs 22% for CRS of 3-4 at 1 y after a single ablation; P <.01). CONCLUSIONS CT-guided RF ablation can be used to treat recurrent CLM after hepatectomy. A low CRS is associated with better clinical outcomes.

Abstract
PURPOSE Add systemic bevacizumab (Bev) to adjuvant hepatic arterial infusion (HAI) plus systemic therapy after liver resection to increase recurrence-free survival (RFS). PATIENTS AND METHODS Patients were randomly assigned to HAI plus systemic therapy with or without Bev. If 1-year RFS of ≥ 80% was obtained in Bev arm, then the regimen would be studied further. HAI with fluorodeoxyuridine plus dexamethasone was given on days 1 to 14 of a 5-week cycle. Systemic therapy and Bev 5 mg/kg was delivered on days 15 and 29: oxaliplatin 85 mg/m², leucovorin 400 mg/m², and fluorouracil 2,000 mg/m² infusion for 2 days (if patients received prior oxaliplatin, then irinotecan 150 mg/m² was used). RFS and survival were estimated by using the Kaplan-Meier method and compared by using the log-rank test. RESULTS The two arms had similar characteristics: synchronous disease (66% v 63%), more than one metastasis (84% v 74%), and clinical risk score ≥ 3 (50% v 46%) for no Bev versus Bev arms, respectively. With a median follow-up of 30 months, 4-year survival was 85% and 81% (P = .5), and 4-year RFS was 46% versus 37%; 1-year RFS was 83% and 71% (P = .4) for no Bev versus Bev arms. Bilirubin > 3 mg/dL was seen in zero of 38 versus five of 35 patients (P = .02) and biliary stents were placed in zero versus four patients (P = .05) in no Bev versus Bev arms. CONCLUSION The addition of Bev to adjuvant HAI plus systemic therapy after liver resection did not seem to increase RFS or survival but appeared to increase biliary toxicity. Four-year survival was 85% and 81% for no Bev and Bev arms, respectively.

Abstract
Hepatic metastases are common with colorectal cancer. The primary blood supply to hepatic metastases is the hepatic artery. Regional chemotherapy utilizing the hepatic artery is one treatment option for liver metastases. The advantage of hepatic arterial chemotherapy is that high concentrations of the therapeutic drug are obtained in the liver with minimal systemic toxicity. Recently, systemic chemotherapy regimens have been added to hepatic arterial infusional chemotherapy to treat hepatic metastases. Due to the high response rates in the liver, resection rates are increasing in patients originally thought to have unresectable liver disease. Hepatic arterial chemotherapy has also been used in the adjuvant setting after resection of all liver metastases in order to minimize hepatic recurrences. The role of hepatic arterial infusional therapy in treating hepatic colorectal metastases includes treating patients with both resectable and unresectable metastases in the adjuvant, neoadjuvant, or palliative settings.

Abstract
BACKGROUND The authors investigated how the timing of administration of bevacizumab, a targeted vascular endothelial growth factor-inhibiting chemotherapeutic agent, affected the risk of wound healing in patients undergoing chest wall port placement. METHODS The authors performed a retrospective search was performed of an institutional review board approved, Health Insurance Portability and Accountability Act compliant database between 2002 and 2008, identifying 1108 port placements in patients who were treated with bevacizumab. One hundred twenty of these ports eventually required explant. Data analyzed included patient demographics, indication for port removal, and schedule of bevacizumab therapy. RESULTS Wound healing complications requiring port explant were seen in 0.9% of placements (10/1108). When bevacizumab was given within 1 day of port placement, the absolute risk (AR) of port removal for wound dehiscence was 2.4% (2/82), compared with 0.3% (3/1021) when 2 or more days had passed between port placement and bevacizumab administration, yielding a statistically significant relative risk (RR) of 8.1 (P < .02). Similarly, when bevacizumab was administered within 7 days of port insertion, there was a significant RR of dehiscence-related port explant (AR 1.4% vs 0.1%, RR 11.5, P < .028). However, no significant RR for dehiscence-related port removal was observed when bevacizumab was administered within 14 days (AR 0.9% vs 0.2%, RR 6.2, P < .09) or 30 days (AR 0.7% vs 0.2%, RR 3.7, P < .23) of port placement. CONCLUSIONS The risk of a wound dehiscence requiring chest wall port explant in patients treated with bevacizumab was inversely proportional to the interval between bevacizumab administration and port placement, with significantly higher risk seen when the interval is less than 14 days.

Abstract
Resection of colorectal liver metastases (CLM) is the ultimate aim of treatment strategies in most patients with liver-confined metastatic colorectal cancer. Long-term survival is possible in selected patients with initially resectable or unresectable CLM. As a majority of patients have unresectable liver disease at the outset, there is a clear role for chemotherapy to downstage liver disease making resection possible. Studies of systemic chemotherapy with or without biologic therapy in patients with unresectable CLM have resulted in increased response rates, liver resection rates and survival. A sound physiologic rationale exists for the use of hepatic arterial infusion (HAI) therapy. Studies have shown that HAI with floxuridine combined with systemic chemotherapy increases response rates and liver resection rates in those patients with initially unresectable CLM. Toxicity from preoperative chemotherapy, biologic therapy and HAI therapy may adversely affect hepatic resection but can be kept minimal with appropriate monitoring. All conversion strategies should be decided by a multidisciplinary team.

Abstract
A 72-year-old man was diagnosed with a poorly differentiated hepatic flexure mass seen on routine screening colonoscopy. He underwent a right hemicolectomy and biopsy of a liver lesion noted at laparotomy. Pathology revealed a high-grade neuroendocrine carcinoma in the primary tumor and the liver lesion. Post-operative imaging revealed an isolated FDG avid liver metastases which had not been appreciated pre-operatively. He was treated with combination platinum and etoposide for extensive stage small-cell carcinoma of the colon. After 6 cycles of chemotherapy, the isolated liver lesion remained FDG avid, albeit less than baseline. Radiofrequency ablation of the avid liver lesion was performed. Further, chemotherapy was given as the lesion remained FDG avid. Ablation was repeated and a subsequent biopsy was positive. Chemotherapy resumed for a total of 10 cycles. Repeat PET scan became negative and the patient remains disease-free 7 years from an initial diagnosis of extensive stage small-cell colon cancer with a negative PET scan. Aggressive locoregional treatment is an option in patients with extensive stage small-cell carcinoma of the colon who are left with an oligometastasis after platinum-based systemic chemotherapy.

Abstract
Colorectal cancer metastases to the liver are primarily supplied by the hepatic artery. Therefore, delivery of regional chemotherapy via the hepatic artery is a viable treatment option. Chemotherapy can be delivered in high concentration to the liver with minimal systemic toxicity. Hepatic artery infusional (HAI) chemotherapy both alone and in combination with systemic chemotherapy in the treatment of isolated hepatic metastases from colorectal cancer has resulted in high response rates and increased resection rates for previously unresectable liver disease. Regional chemotherapy can also be used as adjuvant treatment after complete resection of liver metastases to reduce hepatic recurrences. The combination of HAI therapy with modern systemic chemotherapy has a role in the palliative, adjuvant, and neoadjuvant settings.

Abstract
BACKGROUND During chemotherapy, some colorectal liver metastases (LMs) disappear on serial imaging. This disappearance may represent a complete response (CR) or a reduction in the sensitivity of imaging during chemotherapy. The objective of the current study was to determine the fate of disappearing LMs (DLMs) and the factors that predict a true CR. METHODS Between 2000 and 2003, 435 patients who were evaluated by hepatobiliary surgeons received chemotherapy before they were considered for resection. Inclusion criteria were <12 LMs before chemotherapy, at least 1 DLM on a computed tomography (CT) scan, and either surgical resection or 1 year of clinical follow-up after the disappearance of LMs. A true CR was defined as either a pathologic CR (no tumor detected in the resection specimen) or a durable clinical CR (did not reappear on follow-up imaging). Clinical and pathologic factors were analyzed to identify those associated with a true CR. RESULTS During chemotherapy, 39 patients (9%) had a total of 118 DLMs on follow-up CT scans. Sixty-eight DLMs were resected, and 50 were followed clinically. Overall, 75 DLMs (64%) were true CRs, including 44 pathologic CRs and 31 durable clinical CRs. On multivariate analysis, the use of hepatic arterial infusion (HAI) chemotherapy (odds ratio [OR], 6.2; P = .02), the inability to observe the DLM on a magnetic resonance image (OR, 4.7; P = .005), and normalization of serum carcinoembryonic antigen levels (OR, 4.6; P = .006) were associated independently with a true CR. CONCLUSIONS Approximately 66% of DLMs represented a true CR according to assessment by resection or radiologic follow-up. Predictive factors may help to stratify patients who are likely to harbor residual disease.

Abstract
Liver resection is the goal of treatment strategies for liver-confined metastatic colorectal cancer. However, after resection the majority of patients will experience recurrence. Chemotherapy seems to improve outcomes compared with surgery alone. We reviewed the data of the role of adjuvant chemotherapy after resection of liver- confined metastatic colorectal cancer. Optimal regimens and sequencing of chemotherapies when liver resection is an option are unclear. Some suggest that resectable liver metastases, in the absence of high-risk features, should begin with surgery and consideration given to adjuvant chemotherapy after surgery. If high-risk features are present, most physicians prefer a short course of systemic preoperative chemotherapy. Perioperative therapy and regional therapy with hepatic arterial infusion (HAI) both increase disease-free survival (DFS) when compared with surgery alone. In unresectable disease, consideration should be given to systemic chemotherapy with or without a biologic agent or HAI with systemic therapy. If the disease becomes resectable, adjuvant treatment should follow surgery. Adjuvant chemotherapy is usually FOLFOX, but HAI combined with systemic chemotherapy is also an option. The role of adjuvant treatment post-liver resection should not be viewed in isolation but rather in the context of prior treatment, surgical preference, and individual patient characteristics. Perioperative therapy and regional therapy have both shown an increase in DFS. Conducting randomized trials examining the role of adjuvant chemotherapy has been difficult because of rapidly changing chemotherapies.

Abstract
PURPOSE The purpose of this study was to describe the frequency of interventions necessary to palliate the intact primary tumor in patients who present with synchronous, stage IV colorectal cancer (CRC) and who receive up-front modern combination chemotherapy without prophylactic surgery. PATIENTS AND METHODS By using a prospective institutional database, we identified 233 consecutive patients from 2000 through 2006 with synchronous metastatic CRC and an unresected primary tumor who received oxaliplatin- or irinotecan-based, triple-drug chemotherapy (infusional fluorouracil, leucovorin, and oxaliplatin; bolus fluorouracil, leucovorin, and irinotecan; or fluorouracil, leucovorin, and irinotecan) with or without bevacizumab as their initial treatment. The incidence of subsequent use of surgery, radiotherapy, and/or endoluminal stenting to manage primary tumor complications was recorded. RESULTS Of 233 patients, 217 (93%) never required surgical palliation of their primary tumor. Sixteen patients (7%) required emergent surgery for primary tumor obstruction or perforation, 10 patients (4%) required nonoperative intervention (ie, stent or radiotherapy), and 213 (89%) never required any direct symptomatic management for their intact primary tumor. Of those 213 patients, 47 patients (20%) ultimately underwent elective colon resection at the time of metastasectomy, and eight patients (3%) underwent this resection during laparotomy for hepatic artery infusion pump placement. Use of bevacizumab, location of the primary tumor in the rectum, and metastatic disease burden were not associated with increased intervention rate. CONCLUSION Most patients with synchronous, stage IV CRC who receive up-front modern combination chemotherapy never require palliative surgery for their intact primary tumor. These data support the use of chemotherapy, without routine prophylactic resection, as the appropriate standard practice for patients with neither obstructed nor hemorrhaging primary colorectal tumors in the setting of metastatic disease.

Abstract
PURPOSE To determine the conversion to resectability in patients with unresectable liver metastases from colorectal cancer treated with hepatic arterial infusion (HAI) plus systemic oxaliplatin and irinotecan (CPT-11). PATIENTS AND METHODS Forty-nine patients with unresectable liver metastases (53% previously treated with chemotherapy) were enrolled onto a phase I protocol with HAI floxuridine and dexamethasone plus systemic chemotherapy with oxaliplatin and irinotecan. Results Ninety-two percent of the 49 patients had complete (8%) or partial (84%) response, and 23 (47%) of the 49 patients were able to undergo resection in a group of patients with extensive disease (73% with > five liver lesions, 98% with bilobar disease, 86% with > or = six segments involved). For chemotherapy-naïve and previously treated patients, the median survival from the start of HAI therapy was 50.8 and 35 months, respectively. The only baseline variable significantly associated with a higher resection rate was female sex. Variables reflecting extensive anatomic disease, such as number of lesions or number of vessels involved, were not significantly associated with the probability of resection. CONCLUSION The combination of regional HAI floxuridine/dexamethasone and systemic oxaliplatin and irinotecan is an effective regimen for the treatment of patients with unresectable liver metastases from colorectal cancer, demonstrating a 47% conversion to resection (57% in chemotherapy-naïve patients). Future randomized trials should compare HAI plus systemic chemotherapy with systemic therapy alone to assess the additional value of HAI therapy in converting patients with hepatic metastases to resectability.

Abstract
Liver metastases are mainly supplied by the hepatic artery. Sustained high levels of intratumoral drug are achievable with certain drugs given via the hepatic artery. Floxuridine (FUDR) is an ideal drug for hepatic arterial infusion (HAI) due to its short half life, steep dose response curve, high total body clearance, and high hepatic extraction. HAI FUDR has consistently shown higher response rates than systemic chemotherapy alone, and some studies have shown a survival advantage. HAI FUDR in combination with systemic chemotherapy has evolved over the years and may be used in palliative, neoadjuvant, and adjuvant settings. The dramatic responses observed with HAI FUDR plus modern era systemic chemotherapy offer the possibility of resection and cure in selected patients. The high hepatic extraction of FUDR limits systemic side effects. Toxicity includes biliary and gastrointestinal ulcers.

Abstract
PURPOSE To evaluate the ability of either oral minocycline, topical tazarotene or both, to reduce or prevent cetuximab-related acneiform rash when administered starting on day 1 of cetuximab therapy. PATIENTS AND METHODS Metastatic colorectal cancer patients preparing to initiate cetuximab were randomly assigned to receive daily oral minocycline or placebo, and to receive topical tazarotene application to either left or right side of the face. Both therapies were administered for 8 weeks. RESULTS Forty-eight eligible patients were randomly assigned to minocycline (n = 24) or placebo (n = 24). Total facial lesion counts were significantly lower in patients receiving minocycline at weeks 1 through 4. At week 4, a lower proportion of patients in the minocycline arm reported moderate to severe itch than in the placebo arm (20% v 50%, P = .05). Facial photographs, obtained at week 4, were reviewed for rash global severity. Patients in the minocycline arm trended toward lower frequency of moderate to severe rash than patients receiving placebo (20% v 42%, P = .13). The differences in total facial lesion counts and subjectively assessed itch were diminished by week 8. Cetuximab treatment was interrupted because of grade 3 skin rash in four patients in the placebo arm, and none in the minocycline arm. There was no observed clinical benefit to tazarotene application. Tazarotene treatment was associated with significant irritation, causing its discontinuation in one third of patients. CONCLUSION Prophylaxis with oral minocycline may be useful in decreasing the severity of the acneiform rash during the first month of cetuximab treatment. Topical tazarotene is not recommended for management of cetuximab-related rash.

Abstract
PURPOSE We evaluated the safety and efficacy of concurrent administration of two monoclonal antibodies, cetuximab and bevacizumab, in patients with metastatic colorectal cancer. PATIENTS AND METHODS This was a randomized phase II study in patients with irinotecan-refractory colorectal cancer. All patients were naïve to both bevacizumab and cetuximab. Patients in arm A received irinotecan at the same dose and schedule as last received before study entry, plus cetuximab 400 mg/m2 loading dose, then weekly cetuximab 250 mg/m2, plus bevacizumab 5 mg/kg administered every other week. Patients in arm B received the same cetuximab and bevacizumab as those in arm A but without irinotecan. RESULTS Forty-three patients received cetuximab, bevacizumab, and irinotecan (CBI) and 40 patients received cetuximab and bevacizumab alone (CB). Toxicities were as would have been expected from the single agents. For the CBI arm, time to tumor progression (TTP) was 7.3 months and the response rate was 37%; for the CB arm, TTP was 4.9 months and the response rate was 20%. The overall survival for the CBI arm was 14.5 months and the overall survival for the CB-alone arm was 11.4 months. CONCLUSION Cetuximab and bevacizumab can be administered concurrently, with a toxicity pattern that seems to be similar to that which would be expected from the two agents alone. This combination plus irinotecan also seems to be feasible. The activity seen with the addition of bevacizumab to cetuximab, or to cetuximab plus irinotecan, seems to be favorable when compared with historical controls of cetuximab or cetuximab/irinotecan in patients who are naïve to bevacizumab.

Abstract
BACKGROUND Surgical resection of isolated hepatic or pulmonary colorectal metastases prolongs survival in selected patients. But the benefits of resection and appropriate selection criteria in patients who develop both hepatic and pulmonary metastases are ill defined. STUDY DESIGN Data were prospectively collected from 131 patients with colorectal cancer who underwent resection of both hepatic and pulmonary metastases over a 20-year period. Median followup was 6.6 years from the time of resection of the primary tumor. Patient, treatment, and outcomes variables were analyzed using log-rank, Cox regression, and Kaplan-Meier methods. RESULTS The site of first metastasis was the liver in 65% of patients, the lung in 11%, and both simultaneously in 24%. Multiple hepatic metastases were present in 51% of patients, and multiple pulmonary metastases were found in 48%. Hepatic lobectomy or trisegmentectomy was required in 61% of patients; most lung metastases (80%) were treated with wedge excisions. Median survival rates from resection of the primary disease, first site of metastasis, and second site of metastasis were 6.9, 5.0, and 3.3 years, respectively. After resection of disease at the second site of metastasis, the 1-, 3-, 5-, and 10-year disease-specific survival rates were 91%, 55%, 31%, and 19%, respectively. An analysis of prognostic factors revealed that survival was significantly longer when the disease-free interval between the development of the first and second sites of metastases exceeded 1 year, in patients with a single liver metastasis, and in patients younger than 55 years old. CONCLUSIONS Surgical resection of both hepatic and pulmonary colorectal metastases is associated with prolonged survival in selected patients. Patients with a longer disease-free interval between metastases and those with single liver lesions had the best outcomes.

Abstract
The treatment of metastatic colorectal cancer by chemotherapy alone was considered palliative and without the potential to cure patients unless patients were rendered resectable. We report two patients with metastatic colorectal cancer involving the liver who were considered inoperable and were treated with systemic chemotherapy using biomodulated 5-fluorouracil. Both patients received 5-fluorouracil and N-(phosphonoacetyl)-l-aspartic acid; one also received methotrexate, leucovorin, and triacetyluridine with the N-(phosphonoacetyl)-l-aspartic acid and 5-fluorouracil. Both patients had a complete remission with chemotherapy and are still alive with no evidence of cancer ten years after the diagnosis of unresectable metastatic disease. These patients provide evidence that prolonged survival can be achieved withsystemic chemotherapy without the use of surgery or other forms of local therapy. These patients also confirm the importance of continued investigation of fluorouracil modulating agents, which may further enhance the recent progress made with fluorouracil-based combination chemotherapy for colorectal cancer.

Abstract
PURPOSE Hepatic metastases derive most of their blood supply from the hepatic artery; therefore, for patients with hepatic metastases from colorectal cancer, hepatic arterial infusion (HAI) of chemotherapy may improve outcome. METHODS In a multi-institutional trial, 135 patients were randomly assigned to receive HAI versus systemic bolus fluorouracil and leucovorin. The primary end point was survival; secondary end points were response, recurrence, toxicity, quality of life, cost, and the influence of molecular markers. RESULTS Overall survival was significantly longer for HAI versus systemic treatment (median, 24.4 v 20 months; P = .0034), as were response rates (47% and 24%; P = .012) and time to hepatic progression (THP; 9.8 v 7.3 months; P = .034). Time to extrahepatic progression (7.7 v 14.8 months; P = .029) was significantly shorter in the HAI group. Quality-of-life measurements showed improved physical functioning in the HAI group at the 3- and 6-month follow-up assessments. Toxicity included grade > or = 3 neutropenia (2% and 45%; P < .01), stomatitis (0% and 24%; P < .01), and bilirubin elevation (18.6% and 0; P < .01) in the HAI and systemic treatment groups, respectively. A greater proportion of men versus women receiving HAI experienced biliary toxicity (37% and 15%, respectively; P = .05). For HAI patients with thymidylate synthase levels in tumor less than or > or = 4, the median survival was 24 and 14 months, respectively (P = .17). CONCLUSION HAI therapy increased overall survival, response rate, THP, and was associated with better physical functioning compared with systemic therapy. Additional studies need to address the overall benefit and cost of new chemotherapy agents versus HAI alone or the combination of HAI with new agents.

Abstract
In recent years, a number of phase III clinical trials have reported median survival times approaching 20 months using modern combination chemotherapy for metastatic colorectal cancer (CRC). Despite the advances in systemic therapy, this approach is still considered palliative because long-term survival or cure is extremely rare. Surgery or the use of ablative techniques may result in prolonged survival for patients with liver metastases, but only a minority of cases are suitable for local therapy. Hepatic arterial infusion (HAI) therapy involves local delivery of drug to liver metastases, resulting in higher intrahepatic drug levels and a consequent doubling in response rates compared with systemic chemotherapy. Despite higher response rates, demonstrating a survival advantage for HAI has been more challenging. Recently, a number of studies have been published that appear to address some of the inadequacies of earlier trials and have demonstrated encouraging results. This review assimilates the current data on HAI for CRC and includes an assessment of new chemotherapeutic agents delivered via HAI, neoadjuvant HAI, HAI combined with systemic chemotherapy, the use of HAI for early-stage colorectal cancer, and future trials. Continued progress in the field of HAI therapy may reduce the morbidity and mortality associated with CRC, so continued research in this area should be encouraged.

Abstract
Colorectal carcinoma is one of the most common cancers in the world, and more than 50% of these patients develop liver metastases. Despite recent advances, systemic chemotherapy for metastatic disease without the use of surgery is considered palliative, as there are rarely long-term survivors. However, patients who are candidates for surgical resection of their liver metastases can have a prolonged survival or possibly a cure. Consensus guidelines on criteria for resection and prognostic scores help facilitate patient selection, yet only 25% of patients with liver metastases are considered to have resectable metastases. Neoadjuvant chemotherapy has been explored in an attempt to render more patients candidates for resection. First reports using neoadjuvant systemic chemotherapy in patients with unresectable disease found that 13% to 16% of patients could be rendered resectable. Efforts to increase response rates using hepatic arterial infusion or biologic agents may increase resection rates. This review summarizes the current data on neoadjuvant chemotherapy, the rationale for this approach, potential complications, and future prospects.

Abstract
The optimal management of patients with liver metastases from colorectal cancer is confounded by the large number of options available. In addition to ablative therapy (surgery, cryosurgery, radiofrequency ablation, etc.), chemotherapy plays a key role in the management of these patients. With more effective systemic therapy, some commentators have questioned the role of intra-arterial chemotherapy. However, a careful review of the literature,as well as ongoing research efforts, suggest that this approach remains an important option for patients and physicians to consider in appropriately selected patients for both first- and second-line therapy in advanced disease as well as for adjuvant therapy following resection of liver metastases.

Abstract
PURPOSE To establish evidence of activity, or lack thereof, of cetuximab-based therapy in patients with refractory colorectal cancer with tumors that do not demonstrate epidermal growth factor receptor (EGFR) expression by immunohistochemistry (IHC). PATIENTS AND METHODS Pharmacy computer records were reviewed to identify all patients who received cetuximab at Memorial Sloan-Kettering Cancer Center in a nonstudy setting during the first 3 months of cetuximab's commercial availability. Medical records of these patients were then reviewed to identify colorectal cancer patients who had experienced failure with a prior irinotecan-based regimen and who had a pathology report indicating an EGFR-negative tumor by IHC. Pathology slides from these patients were reviewed by a reference pathologist to confirm EGFR negativity, and computed tomography scans during cetuximab-based therapy were reviewed by a reference radiologist. Response rates were reported using WHO criteria. RESULTS Sixteen chemotherapy-refractory, EGFR-negative colorectal cancer patients who received cetuximab in a nonstudy setting were identified. Fourteen of these patients received cetuximab plus irinotecan, and two received cetuximab monotherapy. In the 16 patients, four major objective responses were seen (response rate, 25%; 95% CI, 4% to 46%). CONCLUSION Colorectal cancer patients with EGFR-negative tumors have the potential to respond to cetuximab-based therapies. EGFR analysis by current IHC techniques does not seem to have predictive value, and selection or exclusion of patients for cetuximab therapy on the basis of currently available EGFR IHC does not seem warranted.

Abstract
We have shown previously that metastatic tumors of human colorectal cancer in lung as compared to liver have high levels of thymidylate synthase (TS) mRNA expression that correlated with high levels of E2F-1 mRNA expression. We now report that Comparative Genomic Hybridization (CGH) and DNA PCR analyses of lung and liver metastases of human colon cancer show frequent gains in the region of chromosome 20q and have an increase in gene copy number of E2F-1. In as much as TS is transcriptionally regulated by E2F-1, these results provide an explanation for the high levels of TS mRNA noted in some tumor samples.

Abstract
Hepatic metastases are a frequent complication of colorectal cancer (CRC), affecting over half of all CRC patients. Resection of isolated metastases can result in long-term survival, but the majority of patients relapse, and most have unresectable disease. Hepatic arterial infusion (HAI) chemotherapy delivers high concentrations of cytotoxic agents directly to liver metastases with minimal systemic toxicities. Advances in surgical techniques, development of fully implantable pumps, and modification of drug regimens have decreased complications and improved patient tolerability. Randomized trials comparing HAI with systemic chemotherapy have demonstrated superior response rates and times to hepatic progression for unresectable disease, and have shown better times to progression and overall survival rates in the adjuvant setting following hepatic resection. HAI chemotherapy has unique toxicities, including chemical hepatitis and biliary sclerosis, which can be mitigated by the addition of dexamethasone to therapy. In an attempt to prevent extrahepatic progression, combinations of HAI with systemic chemotherapy, including newer agents such as irinotecan and oxaliplatin, are currently being investigated, with promising early results.

Abstract
PURPOSE Two consecutive compassionate use studies of oxaliplatin were conducted in the United States and Canada in more than 5000 patients with locally advanced or metastatic colorectal carcinoma who had experienced treatment failure after at least one prior chemotherapy regimen. PATIENTS AND METHODS The main focus was safety. Patients were assigned to treatment with either single-agent oxaliplatin or oxaliplatin in combination with fluorouracil (FU) and with or without leucovorin (LV) in various regimens. Response data collection was not a trial objective, but time to treatment failure (TTF) was recorded in the first cohort (1370 patients). RESULTS All treatment regimens were well tolerated, with an overall incidence of grade 3 or 4 hematologic toxicity of 23.2%, grade 3 or 4 treatment-related gastrointestinal toxicity of 26.4% (including diarrhea, vomiting, and mucositis), and grade 3 neurosensory toxicity 3.9%. Similar results were reported in the second cohort (3806 patients), in which the eligibility criteria were much less restrictive. In the first cohort (in which 83% received prior irinotecan), median TTF was 14 weeks, and was similar for the five regimens combining oxaliplatin and FU with or without LV, but significantly shorter for the single-agent oxaliplatin arm. The overall dose-intensity of oxaliplatin was maintained at 85.5% (range, 80.6% to 94.3%) of that prescribed by protocol (average 36.7 mg/m2/wk). CONCLUSION These data in a heavily pretreated patient population confirm that oxaliplatin is safe when used as a single agent or with a variety of FU-based regimens as salvage therapy in patients with advanced colorectal cancer.

Abstract
PURPOSE Humanized A33 (huA33; IgG1) monoclonal antibody detects a determinant expressed by 95% of colorectal cancers and can activate immune cytolytic mechanisms. The present study was designed to (a) define the toxicities and maximum tolerated dose of huA33 and (b) determine huA33 immunogenicity. EXPERIMENTAL DESIGN Patients (n = 11) with advanced chemotherapy-resistant colorectal cancer received 4-week cycles of huA33 at 10, 25, or 50 mg/m(2)/week. Serum samples were analyzed using biosensor technology for evidence of human antihuman antibody (HAHA) response. RESULTS Eight of 11 patients developed a HAHA response. Significant toxicity was limited to four patients who developed high HAHA titers. In two of these cases, infusion-related reactions such as fevers, rigors, facial flushing, and changes in blood pressure were observed, whereas in the other two cases, toxicity consisted of skin rash, fever, or myalgia. Of three patients who remained HAHA negative, one achieved a radiographic partial response, with reduction of serum carcinoembryonic antigen from 80 to 3 ng/ml. Four patients had radiographic evidence of stable disease (2, 4, 6, and 12 months), with significant reductions (>25%) in serum carcinoembryonic antigen levels in two cases. CONCLUSIONS The complementarity-determining region-grafted huA33 antibody is immunogenic in the majority of colon cancer patients (73%). HAHA activity can be measured reproducibly and quantitatively by BIACORE analysis. Whereas the huA33 construct tested here may be too immunogenic for further clinical development, the antitumor effects observed in the absence of antibody-mediated toxicity and in this heavily pretreated patient population warrant clinical testing of other IgG1 humanized versions of A33 antibody.

Abstract
PURPOSE In previous studies, humanized A33 (huA33) demonstrated modest antitumor activity in chemotherapy-resistant colorectal cancer patients. In addition, unexpected major tumor responses were observed in patients treated with a specific chemotherapy regimen [carmustine, vincristine, fluorouracil, and streptozocin (BOF-Strep)] administered after huA33 protocols. We designed the present Phase I, open label, cohort, dose-escalation study of huA33 and a fixed dose of BOF-Strep to (a) determine the maximum tolerated dose of huA33 immunotherapy administered with chemotherapy, (b) determine whether chemotherapy modifies huA33 immunogenicity, and (c) develop preliminary information regarding antitumor activity. EXPERIMENTAL DESIGN Stage IV fluorouracil/leucovorin and irinotecan-refractory colorectal cancer patients (n = 16) received escalating weekly doses of huA33 (5-40 mg/m(2)) with BOF-Strep chemotherapy. RESULTS Four patients requiring radiotherapy or surgery were removed early. Of 12 evaluable patients, grade 3 and 4 neutropenia (n = 2) and grade 3 thrombocytopenia (n = 1) were observed. Seven of 12 (58.3%) patients developed anti-huA33 activity. Three patients had radiographic partial responses for 7.5, 5.5, and 14 months with greater than 85% decline in serum carcinoembryonic antigen levels. One mixed response (4.5 months with a serum carcinoembryonic antigen decline of 38%) was also observed. CONCLUSIONS huA33 can be safely combined with BOF-Strep chemotherapy. The present report provides compelling evidence supporting our previous observations of major antitumor activity with the combination of huA33 and BOF-Strep chemotherapy. huA33 is still immunogenic when administered with chemotherapy. Future studies to evaluate the immunogenicity of new huA33 antibodies and identify which drugs in the BOF-Strep regimen are critical for enhanced antitumor efficacy are planned.

Abstract
BACKGROUND The optimal use of radical surgery to palliate primary rectal cancers presenting with synchronous distant metastases is poorly defined. We have reviewed stage IV rectal cancer patients to evaluate the effectiveness of radical surgery without radiation as local therapy. METHODS Eighty stage IV patients with resectable primary rectal tumors treated with radical rectal surgery without radiotherapy were identified. Sixty-one (76%) patients received chemotherapy; response information was available for 34 patients. RESULTS Radical resection was accomplished by low anterior resection (n = 65), abdominoperineal resection (n = 11), and Hartmann's resection (n = 4). Surgical complications were seen in 12 patients (15%), with 1 death and 4 reoperations. The local recurrence rate was 6% (n = 5), with a median time to local recurrence of 14 months. Only one patient received pelvic radiotherapy as salvage treatment. One patient required subsequent diverting colostomy. Median survival was 25 months. On multivariate analysis, the extent of metastasis and response to chemotherapy were determinants of prolonged survival. CONCLUSIONS For patients who present with distant metastases and resectable primary rectal cancers, radical surgery without radiotherapy can provide durable local control with acceptable morbidity. The extent of metastatic disease and the response to chemotherapy are the major determinants of survival. Effective systemic chemotherapy should be given high priority in the treatment of stage IV rectal cancer.

Abstract
Approximately 60% of patients diagnosed with colorectal cancer (CRC) will go on to develop hepatic metastases. Although surgical resection is the only curative modality, a majority will not be able to undergo surgery. Alternative methods for treating this population have focused on the feasibility of hepatic arterial infusion (HAI) of chemotherapy. Randomized data in this field have been hampered due to small numbers of patients in some trials, or crossover between groups. However, most trials have suggested an improvement in both overall and progression-free survival with HAI therapy. Dose-limiting toxicity associated with HAI is related to hepatobiliary sclerosis, which has been reduced with the use of dexamethasone as part of the treatment. Current research is underway to improve the rate of extrahepatic metastases in patients undergoing HAI.

Abstract
BACKGROUND Advanced hepatocellular carcinoma has a poor prognosis. In a Phase II clinical trial, two academic centers assessed irinotecan, a topoisomerase-1 inhibitor with broad spectrum clinical activity, in patients who had advanced hepatocellular cancer. METHODS Patients who had had up to one prior chemotherapy regimen were eligible. Bidimensionally measurable disease, a good performance status, and adequate major organ function were required. At a starting dose of 125 mg/m2, irinotecan was administered weekly for 4 weeks followed by a 2 week break, which constituted 1 treatment cycle. Patients were restaged radiologically after two cycles of therapy. Dose attenuations were made as indicated for toxicity. RESULTS Fourteen patients were enrolled over a 10-week period in 1997. There were ten males and four females. The median age was 58 years (range, 38-74 yrs). The Eastern Cooperative Oncology Group median performance status was 1 (range, 0-1). Two patients had prior chemotherapy (14%), and 1 patient (7%) had had radiation. A total of 30 cycles of therapy were delivered (median, 1; range, 1-6). Considerable toxicity was observed, mostly neutropenia, diarrhea, nausea, vomiting, and fatigue. All patients required at least one dose attenuation for toxicity. One partial response (7%; confidence interval, 0-20%) was noted to last 7 months. One patient had transient stable disease, and all others (86%) had progression of disease as their best response. CONCLUSIONS Irinotecan had modest activity in advanced hepatocellular cancer. Toxicity was substantial, presumably reflecting impaired underlying liver function or poor ability to metabolize and eliminate the drug. The current study indicated that continued new therapy assessment is warranted for this disease.

Abstract
BACKGROUND Aggressive treatment of peritoneal metastases from colon cancer by surgical cytoreduction and infusional intraperitoneal (IP) chemotherapy may benefit selected patients. We reviewed our institutional experience to assess patient selection, complications, and outcome. METHODS Patients having surgical debulking and IP 5-fluoro-2'-deoxyuridine (FUDR) plus leucovorin (LV) for peritoneal metastases from 1987 to 1999 were evaluated retrospectively. RESULTS There were 64 patients with a mean age of 50 years. Primary tumor sites were 47 in the colon and 17 in the appendix. Peritoneal metastases were synchronous in 48 patients and metachronous in 16 patients. Patients received IP FUDR (1000 mg/m2 daily for 3 days) and IP leucovorin (240 mg/m2) with a median cycle number of 4 (range, 1-28). The median number of complications was 1 (range, 0-5), with no treatment related mortality. Only six patients (9%) required termination of IP chemotherapy because of complications. The median follow-up was 17 months (range, 0-132 months). The median survival was 34 months (range, 2-132); 5-year survival was 28%. Lymph node status, tumor grade, and interval to peritoneal metastasis were not statistically significant prognostic factors for survival. Complete tumor resection was significant on multivariate analysis (P = .04), with a 5-year survival of 54% for complete (n = 19) and 16% for incomplete (n = 45) resection. CONCLUSIONS Surgical debulking and IP FUDR for peritoneal metastases from colon cancer can be accomplished safely and has yielded an overall 5-year survival of 28%. Complete resection is associated with improved survival (54% at 5 years) and is the most important prognostic indicator.

Abstract
BACKGROUND Unresectable adenocarcinomas of the biliary tree have a very poor prognosis. No good chemotherapeutic regimen is available. Irinotecan has not yet been fully tested in this disease. We evaluated its activity in unresectable bile duct cancers. PATIENTS AND METHODS Twenty-five consecutive eligible patients at our two institutions were treated with irinotecan at a starting dose of 125 mg/m2. A cycle consisted of once-a-week treatments for four consecutive weeks, followed by two weeks of rest. All patients were required to have histologically confirmed diagnosis, clinically documented metastatic or unresectable carcinoma and measurable disease. Patients were evaluated for response, toxicity, and survival. RESULTS A total of 83 cycles of therapy were delivered. Two patients had a partial response (8%; 95% confidence interval (CI): 0%-18%) and ten additional patients had stable disease for at least two months (40%; 95% CI: 20.8%-59.2%). The therapy was well tolerated, with moderate myelosuppression and diarrhea as the main toxicities. The overall median survival was 10 months. CONCLUSIONS Irinotecan has minimal activity in biliary tree carcinomas, but is well tolerated with appropriate supportive care, and produces occasional objective responses.

Abstract
The liver is a common site for developing metastatic disease. Although any malignancy can spread to the liver, the direct passage of blood from the gastrointestinal tract to the liver via the portal circulation results in a high rate of liver metastasis from gastrointestinal tract tumours. Various radiographical tests including computed tomography and magnetic resonance imaging can detect the majority of liver metastases. Surgical resection if feasible is the treatment of choice since it produces a 5-year survival rate of about 30%. However, the majority of the patients relapse after hepatic resection, 50% relapsing in the liver. Systemic chemotherapy produces response rates of 15-30% with a median survival of 10-12 months. It is estimated that 30,000 patients each year in the USA are candidates for regional hepatic therapy. Hepatic arterial chemotherapy, hepatic artery embolization, chemoembolization, cryosurgery, ethanol injection of the tumour and radiation therapy are being investigated as potential treatment options for such patients.

Abstract
Hepatic metastases are a major cause of morbidity and mortality for patients with colorectal cancer (CRC). The rationale for hepatic arterial chemotherapy has both an anatomical and pharmacological basis. Several randomized clinical studies of fluoropyrimidine showed higher response rates in all trials when the drug was given as an hepatic arterial infusion (HAI) versus systemic administration. However, the studies did not accurately define survival for the following reasons: (1) some allowed a crossover; (2) some were too small; and (3) some used inadequate systemic chemotherapy. Patients who have failed to respond to previous systemic chemotherapy have an approximately 50% response rate with HAI treatment. Hepatic toxicity, especially biliary sclerosis, is the dose-limiting toxicity, occurring in 6% to 25% of patients. Adding dexamethasone to HAI fluoropyrimidine decreases the hepatobiliary toxicity. The therapeutic benefit of HAI in one study was also demonstrated by an increased time with normal quality of life. To truly define the role of regional therapy in patients with CRC confined to the liver, the current Cancer and Leukemia Group B (CALGB) study is randomizing patients to HAI versus systemic therapy without a crossover to demonstrate if HAI improves survival and/or quality of life in addition to response rates.
