Study Quality and Characteristics Of the five randomized trials, little information on study methodology was reported in one trial published in abstract form 14 ; . Four trials were supported by pharmaceutical grants 12, 14-16 ; , whereas one was led by a cooperative group 13 ; . Method of randomization was reported in only two trials 12, 16 ; . Patient stratification was by ECOG Performance Score PS ; , site of primary disease and number of metastatic sites in two trials 12, 16 ; , by ECOG PS and prior radiotherapy in one trial 13 ; and was not reported in the other trials 14, 15 ; . Three of the trials were double-blind and placebo-controlled with regards to bevacizumab 12, 14, 16 ; . One trial reported that primary analyses were performed by a blinded independent review committee but blinding of patients was not discussed 15 ; . The fifth trial was an open-label study 13 ; . Statistical power to detect a significant difference between groups for primary outcomes was reported in three trials 12, 13, 16 ; . One trial allowed patients in the control arm to cross over to receive bevacizumab at disease progression 15 however, all trials used an intention-to-treat analysis approach. Two of the randomized trials were reported as phase II studies 15, 16 ; . The results of these studies must be interpreted with caution due to the methodological limitations associated with phase II trials. Typically, phase II trials randomized against a standard treatment control are not designed to make statistical comparisons between treatment groups but merely determine whether treatment response falls within the normal range and suggest what treatment effect could be expected in a larger trial. Both randomized phase II trials included in this review were designed to evaluate the efficacy and safety of bevacizumab with 5FU FA compared to 5FU FA alone using statistical comparisons between groups. These studies had relatively small sample sizes, were imbalanced in baseline prognostic characteristics between treatment groups and were statistically powered to detect only large differences between groups with regard to primary endpoints. Results from these trials provide support for further study in larger, more rigorously-controlled phase III trials. Outcomes Randomized Clinical Trials Bevacizumab with 5FU Irinotecan IFL ; A phase III placebo-controlled RCT by Hurwitz et al 12 ; was designed to investigate the efficacy and tolerability of bevacizumab in combination with the Saltz regimen of bolus 5FU FA and irinotecan CPT-11 ; , known as IFL, as first-line treatment of patients with advanced colorectal cancer. 5FU FA and irinotecan were given weekly for four out of six weeks, and bevacizumab was given every two weeks at a dose of 5 mg kg. A third treatment arm of 5FU FA and bevacizumab without irinotecan ; was abandoned after the safety of the addition of bevacizumab to irinotecan was established. Results of this treatment arm are discussed in the 5FU Folinic Acid section of this systematic review. Treatment was continued for 36 weeks or until disease progression, whichever occurred first. Patients with cerebral metastases, significant atherosclerotic disease, proteinuria, or a history of coagulopathy were excluded from that study. The primary endpoint was overall survival OS ; , whereas progression-free survival PFS ; , objective response rate RR ; , and duration of response were all secondary endpoints. A total of 815 patients were randomized to receive IFL with bevacizumab n 403 ; or IFL with placebo n 412 ; . Results are summarized in Table 1. Improvements in median survival 20.3 vs. 15.6 months; p 0.00003 ; , PFS 10.6 vs. 6.2 months; p 0.00001 ; , overall RR 45% vs. 35%; p 0.0029 ; , and response duration 10.4 vs. 7.1 months; p 0.0014 ; were detected with IFL combined with bevacizumab compared with IFL alone. The combination of IFL and bevacizumab was generally well tolerated; however, an increase in grade 3 or 4 toxicity with IFL combined with bevacizumab 85% vs. 74% ; compared to IFL alone was observed. This discrepancy can be attributed to an increase in grade 3 hypertension 10.9% vs. 2.3% ; , which was treated with oral medications. There was no.

P.305 HER2 NEU EXPRESION IN EGFR NEGATIVE COLORECTAL CANCER LIVER METASTASES AND INFLUENCE ON RESPONSE TO SYSTEMIC CHEMOTHERAPY Z.P. Petrovic1, D. Tarabar1 & R. Doder2 1 Clinic of Gastroenterology. VMA, Belgrade, Serbia; 2Dept. of GI Oncology, Clinic of Gastroen, Belgrade, Serbia Aim: To evaluate expresion of HER2 neu in patients with colorectal cancer EGFR immunohistochemistry IHC ; negative liver metastases and to evaluate response to systemic chemotherapy in this group of patients. Patients and methods: A group of 19 patients with IHC negative EGFR synchronous liver metastases from colorectal cancer were analysed. All patients received cetuximab plus irinotecan and or oxaliplatin based chemotherapy regimen in combination with oral fluoropyrimidines capecitabine. Results: 10 pts. had HER2 NEU IHC positive 3 + ; expresion in liver metastases. HER2 NEU IHC negative liver metastases were present in 9 pts. In patients with HER2 neu negative liver metastases 2 pts. had PR, 1 pts. had SD and 6 pts. had PD after chemotherapy. In patients with HER2 NEU positive liver metastases 3 pts. had PR, 2 pts. had SD and 5 pts. had PD after chemotherapy. Conclusion: The results do not support routine determination of HER2 NEU status in patients with EGFR negative liver metastases from colorectal carcinoma for response to chemotherapy. At this moment the results showed that HER2 NEU positive expresion in patients with EGFR negative liver metastases from colorectal carcinoma have no influence on response to systemic chemotherapy with cetuximab.
Cetuximab plus irinotecan. The single-arm study of cetuximab plus irinotecan reported a median time to progression of 2.9 months. The Phase II trial reported a tumour response rate of 22.9% 17.529.1%, primary end-point ; for patients receiving cetuximab plus irinotecan. The single-arm study of cetuximab plus irinotecan reported a tumour response rate of 15.2% 9.722.3% ; . The Phase II trial suggested that treatment with cetuximab in combination with irinotecan is associated with significantly more adverse events any grade 3 or 4 adverse event ; than cetuximab monotherapy. Key toxicities include the presence of an acne-like rash, diarrhoea, nausea and vomiting, neutropenia, anaemia and asthenia. Merck provided an addendum to their full submission to NICE outlining early HRQoL outcomes from the MABEL study. At baseline, the EuroQol 5D instrument EQ-5D ; -assessed utility was 0.73; this level of utility was seen to remain fairly constant while patients receive cetuximab plus irinotecan over the evaluable period. These data suggest that treatment with cetuximab plus irinotecan does not detract from a patient's baseline level of HRQoL as measured by the EQ-5D. The manufacturer of cetuximab submitted a costeffectiveness model to NICE based on evidence collected within the Phase II trial of cetuximab plus irinotecan versus cetuximab monotherapy. Further analysis of this model by the Assessment Group highlighted flaws in the methods used to extrapolate survival outcomes beyond the study duration. An independent model was developed by the Assessment Group using more robust survival analysis methods. The Assessment Group model suggests that the expected survival duration of patients receiving cetuximab plus irinotecan is 0.79 years 9.5 months ; when the proposed continuation rule is applied. In order to obtain an incremental cost-effectiveness ratio of 30, 000 per LYG, treatment with cetuximab plus irinotecan must provide an additional 0.41 life-years 4.9 months ; over treatment with active best supportive care. This implies that survival in the active supportive care group must be 0.38 years 4.6 months ; or less. In order for cetuximab plus irinotecan to achieve a cost per QALY gained of 30, 000, treatment with cetuximab plus irinotecan must provide an additional 0.65 life-years 7.8 months ; over treatment with active best supportive care. This implies that survival in the and kato.

Exploiting DNA The iconic status of DNA means that it is often exploited in itself as a selling point in cosmetic products. But AGI Dermatics' Yarosh, who founded the company in 1985, focuses on DNA damage and repair pathways that are linked to photoaging. His firm's products deliver to the skin DNA repair enzymes via a `proprietary' liposomal delivery system. Products developed by AGI Dermatics are featured both in their own skin-care line, called Remergent, and several prestige skin-care brands such as Aveda. According to Yarosh, the repair enzymes have potential in the pharmaceutical indication of preventing of skin cancer as well. By marketing Remergent either directly to consumers through the internet or participating dermatologist offices, the company is riding the trend of dermatologist brands. "We are asking consumers to take the next step and asking them to go to the source. Buy us because we are scientists, " says Yarosh. AGI Dermatics is the source for nine different ingredients that appear in prestige brands. The ingredients address different aspects of skin care, such as protection from the sun's harmful rays, oxidative damage, improving the skin barrier and reducing inflammation and employing an innovative liposomal delivery system. AGI Dermatics also has a product, Dimericine T4 endonuclease V in a liposome coat ; in phase 3 clinical trials for treating xeroderma pigmentosum, a rare genetic disease that produces high rates of skin cancer at a young age. Elsewhere, among its wide array of traditional genetic profiling tests, Margate, New Jerseybased GeneLink is also claiming to provide a more individualized approach to skin care based on its single nucleotide polymorphisms SNPs ; assay. Clients are asked to swab the inside of their cheek and send the sample off to Dermagenetics, a wholly owned subsidiary of GeneLink and irinotecan.
Clear expression of the respective transgene mRNAs. When normalized to the internal control, TBP, GL and GMC mRNA levels were found to be indistinguishable and approximately 3-fold greater than the levels of GM RGl transgene RNA Figure 1B ; . The lower apparent efficiency of GM RGl overexpression relative to the other two targeting subunits is consistent with our previous findings in isolated hepatocytes 15, 16 ; . No attempt could be made to correct for the clearly lower level of GM RGl expression, since infusion of higher viral titers began to have toxic effects, as assessed by an increase in the activity of a liver enzyme, aspartyl aminotransferase PGOT ; in the blood of these animals data not shown ; . It should also be pointed out that our main goal was to compare the highly glycogenic targeting subunit GL with our novel construct GMC and kava.
