    Abstract: There is insufficient data to verify whether participation in clinical trials in itself can lead to better clinical outcomes. We have analyzed the characteristics and outcomes of patients who declined to participate in a randomized trial in comparison with those who participated in the trial. Patients and Methods: A randomized trial for naive advanced gastric cancer was offered to 286 patients. The trial investigated the superiority of irinotecan plus cisplatin and the noninferiority of S-1 compared with continuous fluorouracil infusion. We retrospectively reviewed the characteristics and outcomes for both participants and nonparticipants in this trial. Results: Of the 286 patients, 98 (34%) declined to participate in the trial. The rate of declining was significantly higher among younger patients (P = .003), and it varied significantly between attending physicians (range, 23% to 58%; P = .004). There were no other significant correlations between rate of declining and patient characteristics. No significant differences were observed in the clinical outcomes between the participants and nonparticipants, for whom the median survival times were 367 versus 347 days, respectively. The hazard ratio for overall survival, adjusted for other confounding variables, was 1.21 (95% CI, 0.91 to 1.60). No interaction was observed between participation and the various regimens. Conclusion: There was no difference in clinical outcomes between participants and nonparticipants. However, the patient's age and the doctor-patient relationship may have an effect on patient accrual to randomized trials.

    Abstract: e15016 Background: Thougha triplet chemotherapy with D plus CF (DCF) has shown promising activity, high incidence of adverse events (AEs) especially in febrile neutropenia (FN) was observed in previous studies for head and neck cancer (TAX323, 324) and gastric cancer (TAX325). To reduce its AEs with keeping activity, we conducted a multicenter open-label phase I/II study of biweekly D plus CF for AEC. Methods: Eligibility criteria included histologically proven AEC with measurable disease, age 20 to 75, non-resectable or recurrent disease, performance status (PS) 0 to 1. Pts received escalating doses of D (dose level (DL) 1: 30 mg/m 2 , DL 2: 40 mg/m 2 , on days 1, 15) in combination with fixed dose of CF (cisplatin 80 mg/m 2 on day 1, fluorouracil 800 mg/m 2 on days 1-5) repeated every 4 weeks with 3+3 design in phase I part (P-I). The primary endpoint of P-I was dose limiting toxicity (DLT) and that of phase II part (P-II) was response rate (RR) defined by central peer review. Based on a SWOG two stage design (p0=35%, p1=50%; one-sided a=0.1, β =0.2) at least 22 responders among 50 eligible pts should be observed to satisfy the primary endpoint. Results: Between Feb 2009 and Mar 2010, 62 pts were enrolled for P-I and P-II. In P-I, 10 pts were enrolled with DLT of 0/3 in DL1 and 2/7 in DL2. Considering DLT and treatment compliance, the recommended dose for P-II was determined as DL1. Thus, 3 (P-I) and additional 52 pts (P-II) were analyzed: 53 for efficacy (excluded 2 ineligible pts) and 55 for safety. Pts characteristics were as follows: male/female 49/6, age median 61 (range 44 to 75), PS 0/1 39/16. The RR was 62% (95% confidence interval, 48-75%, p 〈 0.0001) by central peer review. Median OS and PFS were 11.1 and 5.8 months. Grade 3/4 toxicity was observed in neutropenia (25%), anemia (36%), hyponatremia (29%), anorexia (24%) and nausea (11%). No grade 3/4 FN was observed. Treatment related death occurred in one patient due to pneumonitis. Conclusions: Biweekly D (30mg/m 2 ) combined with CF showed promising activity and tolerability. A phase III study comparing CF with DCF is warranted. Clinical trial information: UMIN000001737.

    Abstract: e14601 Background: The first-line combined chemotherapy RPMI regimen with bevacizumab (Bmab) in AVF2192g tri al were active. According to the results of efficacy and safety, a fluoropyrimidine (FU) + Bmab regimen is regarded as one of treatment options for 1st-line chemotherapy in many guidelines. We planned a phase II study of modified RPMI regimen with Bmab especially for elderly or frail Pts. Methods: Pts with confirmed unresectable/metastatic colorectal cancer without previous chemotherapy, and not suitable for intensive chemotherapy were enrolled. Pts received modified RPMI regimen (5-FU 600 mg/m2 and l-leucovorin 200 mg/m 2 bolus day 1, 8, 15) and Bmab 5 mg/kg day 1, 15, q4w) until disease progression or study withdrawal. The primary endpoint was overall response rate (ORR), and the secondary endpoints were PFS, OS and safety. Results: 41 Pts were enrolled from 13 institutions. Pts characteristics were as follows; median age 76 (range 56-90); male/female, 18/23; ECOG performance status 0/1/2, 21/19/1. The ORR, the rate of best response, the disease control rate (CR+PR+SD) were 36.6%, 56.1%, 85.4%, respectively. Median follow-up period was 14.4 months(Updated results will be presented). 28 Pts (68%) had objective progression and a patient (2.4%) died without progression. The median PFS and OS were 9.0 months (95%CI, 7.5–19.6) and 24.0 months (95%CI, 20.1–NR). The incidences of grade 3 or 4 adverse events were: leukopenia (7%), neutropenia (24%), thrombocytopenia (2%), diarrhea (5%), anorexia (10%), fatigue (5%), stomatitis (7%) and hypertension (5%). Grade 3 febrile neutropenia and grade 4 pulmonary embolism was observed in one pt. Five pts (12%) discontinued the treatment due to severe or uncontrollable adverse event. Conclusions: The modified RPMI regimen with Bmab showed promising activity, and was well tolerated for elderly or frail Pts. ORR and the median PFS of this regimen were similar to historical data with FU + Bmab. This regimen may be a good option for patients with poor PS or elderly with advantages of not requiring percutaneous port placement nor compliance or oral agents. Clinical trial information: UMIN000002182.

    Abstract: e14126 Background: Previous studies showed that gene mutations (NRAS, BRAF, PIK3CA) are associated with a poor prognosis or resistance of anti-EGFR antibody in metastatic colorectal cancer (mCRC) patients with wild type (WT) of KRAS codon 12/13 (KRAS-WT). However the significance of these biomarkers has not been clarified. In addition, EGFR immunohistochemistry (IHC) and EGFR gene amplification to evaluate the efficacy of anti-EGFR antibody treatment has not been reported for mCRC. Methods: We evaluated tumor response and survival in patients who received anti-EGFR antibody by mutation analysis of KRAS, NRAS, BRAF, and PIK3CA in KRAS-WT patients with mCRC. Tumor DNA samples are obtained from patients treated in our hospital with anti-EGFR antibody between August 2008 and August 2011. Results: A total of 117 patients were enrolled in this analysis, including 100 KRAS-WT patients. Seventy-one patients (60.7%) were all WT for KRAS, NRAS, BRAF, and PIK3CA, and 46 patients (39.3%) had at least 1 mutation or had insufficient DNA samples to analyze. Mutations of KRAS codon 61 (2 patients), KRAS codon 146 (5), BRAF V600E (2), PIK3CA exon9 (8), NRAS codon 12/13 (2), and NRAS codon 61 (5) were detected. No patients had a mutation of PIK3CA exon 20. Patients with at least 1 mutation had no response. Mutations of NRAS codon 61, KRAS codon 146, and BRAF V600E were associated with a shorter progression free survival (PFS) compared with all WT patients (p=0.049, p=0.004, p=0.036, respectively). Twelve patients (12% of KRAS-WT patients) with a mutation of NRAS codon 61, KRAS codon146, and BRAF V600E had poor prognosis compared with the other KRAS-WT patients (PFS, 6.4 vs 2.0 months, p 〈 0.001; overall survival (OS), 13.7 vs 7.9 months, p=0.012). In all WT patients, moderate to strong EGFR IHC was associated with a better response rate than negative and weak IHC (p=0.046). Conclusions: Mutations of NRAS codon 61, KRAS codon 146, and BRAF V600E could be a strong prognostic factor of anti-EGFR antibody in patients with mCRC. Combination of IHC and DISH of EGFR could identify patients with a tumor response to anti-EGFR antibody in patients that are all WT for KRAS, NRAS, BRAF, and PIK3CA.

    Abstract: 516 Background: KRAS mutation status is a strong predictive factor for anti-EGFR monoclonal antibody therapy efficacy in metastatic colorectal cancer (mCRC). In the BOND trial, objective response rates to cetuximab in irinotecan-refractory mCRC were not significantly different based on the intensity of EGFR staining by immunohistrochemistry (IHC). However, this result was not evaluated by KRAS mutation status, so we retrospectively evaluated the relationship between the efficacy of chemotherapy containing cetuximab and the intensity of membranous EGFR staining in KRAS wild type (KRAS-WT) patients. Methods: Between August 2008 and July 2011, specimens of 391 CRC patients were collected by endoscopic biopsy or surgical resection. EGFR staining by IHC and genetic screening for KRAS status were performed and intensity of EGFR staining was scored by the Guidelines for Interpreting EGFR pharmDx, DAKO. We analyzed 94 KRAS-WT patients who received combination chemotherapy with an irinotecan-regimen plus cetuximab or cetuximab monotherapy and met the following criteria: histologically proven mCRC adenocarcinoma , at least 1 previous regimen of standard fluoropyrimidine - containing chemotherapy , ECOG PS score 0-2, and adequate hepatic and renal function. Patients were classified into 2 groups by intensity of EGFR staining: (A) absence of staining and weakly to moderately positive (IHC 1+ and IHC 2+), (B) strongly positive (IHC 3+). Progression-free survival (PFS) and overall survival (OS) were estimated by the Kaplan-Meier method, and compared in Groups A and B by the log-rank test. Results: There was no significant difference in patient characteristics between the 2 groups except for primary site. The median PFS of Groups A (n=76) and B (n=18) were 5.4 months and 9.1 months (p= 0.029), the median OS was 8.1 months and 13.2 months (p=0.054) and response rate was 20.1% and 33.3%, respectively. Conclusions: In KRAS-WT patients with fluoropyrimidine-containing chemotherapy-refractory mCRC, strong intensity of EGFR staining by IHC might be predictive for efficacy of chemotherapy containing cetuximab.

    Abstract: 435 Background: Recently, liver resection becomes possible by intensive chemotherapy, i.e. conversion chemotherapy, in patients with initially unresectable colorectal liver metastases (CLM). But the criteria for non-resectability varies one team to another, and there are few reports about the clinical benefit of conversion chemotherapy followed by liver resection. Methods: Our criteria for resectability of CLM depends on the size of remnant liver volume ( 〉 30%) and expected function after the removal of all metastases, regardress of number and size of CLM. From December 2007 to September 2011, 113 patients were diagnosed as CLM without extra-hepatic metastases and received chemotherapy. 47 patients were initially diagnosed as resectable and received hepatic resection after chemotherapy (resected group). 66 patients were initially diagnosed as unresectable, but 11 patients become resectable after chemotherapy (conversion group) and 55 patients remain unresectable in spite of chemotherapy (unresecetd group). We assessed the survival benefit between these 3 groups, retrospectively. Results: 110 patients received oxaliplatin-based regimen and 3 irrinotecan-based regimen. In coversion group, 8 patients received cetuximab containing regimen and 2 received bevacizumab containing regimen. 46 of 47 patients in resected group received R0 resection and 7 of 11 patients in conversion group. No serious postoperative complications were observed in resected and conversion group, but the incidence of a surgical site infection in conversion group was somewhat higher than in resected group. Median disease-free survival was significantly higher in the resected group than conversion group (16.73 months [95% CI: 7.80~25.47] and 3.83 months [95% CI: 0.35~7.31 months] ) (P=0.031). And median overall survival (OS) was also higher in resected group, but not significant. In resected and conversion group, median OS was significantly higher than in unresected group. (52.20 vs 39.37 vs 20.57 months (p 〈 0.001)). Conclusions: The recurrence rate was higher in coversion group, but conversion chemotherapy followed by hepatic resection seems to be promising and feasible strategy in initially unresectable CLM patients.

    Abstract: 137 Background: Recurrence after definitive chemoradiotherapy (dCRT) for locally advanced esophageal cancer is associated with poor outcome. No standard treatment strategy exist for recurrence after complete response (CR) to dCRT. We examined patterns of recurrence and clinical outcomes in patients with disease recurrence after dCRT. Methods: We retrospectively investigated 197 patients who had achieved initial CR after dCRT for locally advanced esophageal cancer between January 2000 and December 2008. We analyzed data from the 69 patients who had developed disease recurrence after CR, excluding 11 who died of other causes. Time to event was calculated by the Kaplan-Meier method, and the Cox proportional hazard model was used in univariate and multivariate analyses. Results: Characteristics of the 69 patients were as follows: male: female = 61:8; median age = 65 years (range 47 to 82); clinical stage at diagnosis (UICC 6th edition) IIA/IIB/III = 15/22/32; and performance status at recurrence (0/1/2) = (35/32/2). Primary CRT consisted of 5-FU+cisplatin (n = 66), 5-FU+nedaplatin (n = 2), or S-1+cisplatin (n = 1). The pattern of recurrence was locoregional failure (n = 35), or any distant failure (n = 34). Median time to recurrence from the start of dCRT was 13.6 months, and median survival time after recurrence was 17.4 months. Median survival time according to pattern of failure was 27.5 months (locoregional failure), and 17.4 months (any distant failure). In the univariate analysis, locoregional failure (HR 0.51), time to recurrence 〉 13 months (HR0.38), clinical stage II (HR0.48), and any treatment for recurrence (HR: 0.15) were associated with better prognosis after recurrence. In the multivariate analysis, only time to recurrence ( 〉 13 months) was associated with better prognosis with HR 0.31(95%CI:0.14-0.66) Conclusions: Our study suggested that patients with early recurrence have a poor prognosis. More intensive treatment is needed to improve survival.

    Abstract: 573 Background: The first-line combined chemotherapy RPMI regimen with bevacizumab (Bmab) in AVF2192g trial for elderly or frail patients (Pts) could be active to progression free survival (PFS), the secondary endpoint, although it may not prolong overall survival (OS), the primary endpoint. According to the results of efficacy and safety studies, a fluoropyrimidine (FU) + Bmab regimen is regarded as an option for 1st-line chemotherapy. We planned a phase II study of modified RPMI regimen with Bmab for elderly or frail Pts. Methods: Pts with confirmed unresectable/metastatic colorectal cancer without previous chemotherapy, and not suitable for intensive chemotherapy were enrolled. Pts received modified RPMI regimen (5-FU 600 mg/m2 and l-leucovorin 200 mg/m 2 bolus day 1, 8, 15) and Bmab 5 mg/kg day 1, 15, q4w) until disease progression or study withdrawal. The primary endpoint was overall response rate (ORR), and the secondary endpoints were PFS, OS and safety. Results: 41 Pts were enrolled from 13 institutions. Pts characteristics were; median age 76 (range 56-90); male/female, 18/23; ECOG performance status 0/1/2, 21/19/1. The ORR, the rate of best response, the disease control rate (CR+PR+SD) were 36.6%, 56.1%, 85.4%, respectively. Median follow-up period was 14.4 months. 28 Pts (68%) had objective progression and a patient (2.4%) died without progression. The median PFS and OS were 9.0 months (95%CI, 7.5–19.6) and 24.0 months (95%CI, 20.1–NR). The incidences of grade 3 or 4 adverse events were: leukopenia (7%), neutropenia (24%), thrombocytopenia (2%), diarrhea (5%), anorexia (10%), fatigue (5%), stomatitis (7%) and hypertension (5%). Grade 3 febrile neutropenia and grade 4 pulmonary embolism was observed in one pt. Five pts (12%) discontinued the treatment due to severe or uncontrollable adverse event. Conclusions: The modified RPMI regimen with Bmab showed activity, and was well tolerated for elderly or frail Pts. ORR and the median PFS of this regimen were similar to historical data with FU + Bmab. This regimen may be a good option for not requiring percutaneous port placement Pts. Clinical trial information: UMIN000002182.

    Abstract: 438 Background: Colorectal adenoma is a well-established precursor lesion of colorectal cancer, so the prevention of adenoma may also contribute to the prevention of cancer. Adipocyte secretes hormones, namely adipocytokines, some of which are likely to be associated with malignancies such as colorectal, breast, and prostate gland cancer. Among several adipocytokines, resistin and visfatin have been suggested to be associated with the progression of colon cancer, and they could therefore be good biomarkers for colorectal adenoma and cancer. Methods: Prior to any procedures, healthy volunteers provided their venous blood, from which we obtained the plasma to measure concentrations of adiponectin, visfatin, and resistin. We underwent total colonoscopy, and identified 776 adenoma cases (522 males, 254 females), 734 controls (478 males, 256 females) were selected from those without adenoma. An unconditional logistic regression model was used to estimate odds ratios for colorectal adenoma after adjustment for potential confounders, including body mass index (BMI). Results: We found no positive association between the presence of colorectal adenoma and the levels of either visfatin (P trend: male 0.24, female 0.87), or resistin (P trend: male 0.85, female 0.71). After adjusting for potential confounders, we still saw no association. On the other hand, adiponectin levels showed a correlation with both BMI (P: male 〈 0.0001, female 0.0007) and the volume of fat. Furthermore, adiponectin levels indicated no positive correlation with visfatin (P: male 0.656, female 0.1445) or resistin (P: male 0.2116, female 0.1352). Conclusions: In this study, no association was observed between visfatin/resistin levels and colorectal adenoma, and they showed no positive correlation with BMI or the volume of intra-abdominal fat. However, other confounders may account for these results, so we plan to conduct further differential analyses.

    Abstract: 607 Background: Anti-epidermal growth factor receptor (EGFR) antibody therapy showed to be effective in treatment for metastatic colorectal cancer (mCRC) with wild KRAS. Especially, combination chemotherapy with anti-EGFR antibody plus irinotecan is expected more effective than anti-EGFR antibody alone, resistant to irinotecan. We conducted a phase II trial of panitumumab plus irinotecan for mCRC with wild KRAS resistant to fluoropyrimidine, oxaliplatin, and irinotecan in Japanese. Methods: Subjects were mCRC patients with wild KRAS, who showed resistance to fluoropyrimidine, oxaliplatin, and irinotecan and had measurable disease, ECOG PS 0-2. Panitumumab (6 mg/kg) plus irinotecan (same dose as prior irinotecan) was administered every two weeks. This treatment was provided until progression. The primary endpoint was response rate (RR). Secondary endpoints were disease control rate (DCR), progression-free survival (PFS), overall survival (OS), response duration, and adverse event (AE). Results: A total of 31 subjects were enrolled between July 2010 and July 2012. Median age was 64 years old (range 42-74). Nineteen patients had liver metastasis, 11 had lung metastasis, and 3 had lymph node metastasis. An independent review committee evaluated for efficacy in eligible 31 subjects in accordance with the Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1. The RR of primary endpoint was 29.0% (95% confidence interval (CI), 14.2-48.0 %). DCR was 74.2% (95%CI, 55.4-88.1%) and median PFS was 5.6 months.(95%CI: 3.4-8.7) In 31 subjects for safety evaluation, the incidence of any Grade 3 or greater adverse events was 58.1%. Major adverse events of grade 3 were diarrhea (19.4%), rash acneiform (12.9%), fatigue (9.7%), anorexia (9.7%). A sudden death and an infusion related reaction were occurred. Conclusions: Combination chemotherapy with panitumumab plus irinotecan was demonstarated to be safe and more effective than Japanese single arm phase II of panitumumab alone for mCRC, resistant to fluoropyrimidine, oxaliplatin and irinotecan. This result in Japanese is equal to other reports of panitumumab plus irinotecan. Clinical trial information: UMIN000003819.
