    Kurzfassung: 204 Background: Patients with metastatic or recurrent esophageal squamous cell carcinoma (ESCC) have a poor prognosis. For decades, 5-fluorouracil /Cisplatin (FP) have been mostly used for these patients as first line chemotherapy. But there were few reports which reveal the reality containing the efficacy of FP regimen for ESCC. We conduct this retrospective study to reveal the efficacy and prognostic factors of the patients treated with FP as first line chemotherapy for ESCC. Methods: Patients with metastatic or recurrent ESCC after esophagectomy were enrolled. FP comprised of CDDP at a dose of 80mg/m 2 on day1, and 5-FU at a dose of 800mg/m 2 given by continuous on days 1-5 every 4 weeks. Cox-proportional hazard model was used for multivariate analysis to evaluate prognostic factors. Results: Between April 2001 and March 2012 in the National Cancer Center Hospital, data of 187 patients were collected by medical records. Characteristics of 187 patients were as follows; the median age (range) 62 (34-84); (male/female) 163/24; (performance status: 0/1/2) 69/110/8; (metastatic/recurrent) 116/71; median number of metastasis 1(range1-4); median cycles of FP 2(range1-10). Overall response rate was 31.6% (95%CI: 25.0-38.7%). Median progression free and overall survival time was 4.9 month and 10.5 month, respectively. In multivariate analysis, serum CRP (≥2 vs 〈 2 mg/dl) (HR=2.61, p 〈 0.001), serum albumin ( 〈 3.5 vs 〉 3.5 mg/dl) (HR=1.85, p=0.001) at the time of diagnosis and number of metastatic site (≥2 vs 〈 2) (HR=1.563, p=0.01) were remaining independent prognostic factor for survival. Survival time of the patients who had no these poor prognostic factors was 17.9 month, while survival time who had all poor prognostic factors was only 4.0 month. Conclusions: Number of metastatic site, CRP, and serum albumin are independent prognostic factor on metastatic or recurrent ESCC patients treated with FP. Information from this analysis can be used to aid clinical decision-making and help individual patient risk stratification.

    Kurzfassung: 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.

    Kurzfassung: 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.

    Kurzfassung: 96 Background: Definitive chemoradiotherapy is one of the options for stage II/III esophagealsquamous cell carcinoma (ESCC). RTOG9405 recently reported that a higher dose of radiation did not confer any additional survival benefit over the standard dose (50.4 Gy). We comparedthe long-term toxicities conferred by chemoradiation at a dose of 60 Gy and 50.4 Gy for stage II/III ESCC. Methods: Eligibility criteria included clinical stage II/III (non-T4) (UICC-TNM, 6 th edition) ESCC, performance status 0-2, and age 20-75 years. The study group comprised 254 patients who received definitive chemoradiotherapy as first-line therapy between January 2000 and August 2010 in our hospital. Group J (n=207) received 2 cycles of cisplatin (40 mg/m 2 on days 1 and 8) with fluorouracil infusion (400 mg/m 2 /day on days 1-5 and 8-12), or 2 cycles of cisplatin(70 mg/m 2 on day 1) with fluorouracil infusion (700 mg/m 2 /day on days 1-4) and concurrent radiotherapy at 60 Gy. Group R (n = 47) received 2 cycles of cisplatin (75 mg/m 2 on day 1) with fluorouracil infusion (1000 mg/m 2 /day on days 1–4) and concurrent radiotherapy at 50.4 Gy. Long-term toxicity was evaluated according to the Common Terminology Criteria for Adverse Event Ver. 3.0. Results: The characteristics of both groups are as follows (J:R group): median age, 64:63; male/female, 178/29:42/5; PS 0/1/2, 90/104/1:33/14/0; stage IIA/IIB/III: 48/58/101:6/20/21. The median follow-up period was more than 60 months for both groups, with 5-year survival rates of 43.6% and 58.6% for the J and R group, respectively. The proportion of patients with grade 3/4 long-term toxicity in each group was as follows (J/R group): pleural effusion, (8.7%/0%; p = 0.036); pericardial effusion, (6.7%/2.1%; p = 0.196); radiation pneumonitis, (2.4%/4.2%); esophagitis, (0.9%/0%); and pericarditis, (2.4%/0%). Grade 3/4 late toxicity was observed more frequently in the J group (15.0%) than in the R group (6.4%) (p = 0.087). Treatment-related death due to pneumonitis was observed in only 1 patient in group J. Conclusions: The RTOG regimen at a dose of 50.4 Gy showed promising results while inducing lower late toxicity rates than when administered at 60 Gy.

    Kurzfassung: 3559 Background: c-Met is a receptor for hepatocyte growth factor that has been implicated in the pathogenesis and growth of a wide variety of human malignancies, including colorectal cancer (CRC). The aim of the present study was to clarify the correlation between c-Met protein expression in the primary lesion and relapse-free survival (RFS) in patients who had undergone curative hepatectomy for colorectal metastases. Methods: Between January 2004 and December 2009, formalin-fixed paraffin-embedded sections of surgical specimens from 108 CRC patients who had undergone hepatectomy were obtained at a single center. We performed immunohistochemical staining to detect c-Met expression. c-Met expression levels were scored dependent on staining intensity; 0, negative; 1, weak; 2, moderate; 3, strong. We defined scores 0 and 1 as c-Met-low, and scores 2 and 3 as c-Met-high. The Kaplan-Meier method and Cox proportional hazards model were used to investigate relationships between c-Met expression, patient characteristics, and RFS. Results: We identified 65 males and 43 females with a median age of 62 years. A total of 53% of patients underwent simultaneous resection of primary and metastatic liver lesions, and the others underwent metachronous resection. High levels of c-Met expression (c-Met-high) in the primary tumor were observed in 52% of patients. There were no differences in terms of size or number of metastatic liver lesions between the c-Met-low patients and the c-Met-high patients. RFS was significantly shorter in the c-Met-high patients (9.7 months) than that in the c-Met-low patients (21.1 months) in primary tumors (p=0.013). Multivariate analyses demonstrated that c-Met-high (hazards ratio [HR] , 1.73; 95% confidence interval [95% CI], 1.08-2.79 for c-Met-high vs. c-Met-low) and hepatic resection for synchronous disease (HR, 2.17; 95% CI, 1.36-3.46 for synchronous vs. metachronous resection) were associated with worse RFS. Conclusions: High levels of c-Met expression in the primary tumor were associated with shorter RFS after hepatic metastasectomy.

    Kurzfassung: 642 Background: Panitumumab and cetuximab are known to be effective in KRAS wild-type metastatic colorectal cancer (mCRC). However, it is not clear whether panitumumab and irinotecan confers benefit that are comparable to those of cetuximab and irinotecan in patients with KRAS wild-type mCRC previously treated with fluoropyrimidine-, oxaliplatin-, and irinotecan-based regimes. Methods: We analyzed 139 patients who had received panitumumab or cetuximabu combined with irinotecan for KRAS wild-type mCRC previously treated with fluor opyrimidine-, oxaliplatin-, and irinotecan-based regimes.We evaluated and compared efficacy and safety of panitumumab plus irinotecan and cetuximab plus irinotecan. Results: Baseline characteristics were similar for the two groups receving cetuximab pulus irinotecan (n = 97) and panitumumab plus irinotecan (n = 42),respectively.In patients with measurable lesions,the response rate (unconfirmed complete or partial response) were 20% (18/92) in the group receving cetuximab plus irintecan and 34% (14/41) in that receving panitumumab plus irinotecan. Median progression-free survival was 5.7 months in the cetuximab plus irinotecan group versus 4.3 months in the panitumumab plus irinotecan group. Median overall survival was 11.2 months in the cetuximab plus irinotecan group versus 13.6 months in the panitumumab plus irinotecan group. The most common adverse events in the cetuximab plus irinotecan versus panitumumab plus irinotecan groups were all-grade rash acneiform (82% versus 90%), paronychia (61% versus 52%), and grade 3-4 neutropenia (26% versus 19%). Conclusions: Panitumumab or cetuximab plus irinotecan were well tolerated and produced similar response rate and survivals compared to those previous clinical traials.These combinations are cosidered as standard treatment in patients with KRAS wild-type mCRC previously treated with fluoropyrimidine-, oxaliplatin-, and irinotecan-based regimes.

    Kurzfassung: 112 Background: Fluoropyrimidine plus platinum (FP)-based chemotherapy has been widely used as a first-line regimen for advanced or recurrent esophageal cancer (EC). Although the taxanes have shown efficacy in esophageal cancer after FP-based chemotherapy, there is no standard regimen for second-line chemotherapy (SLC). We conducted a retrospective study to investigate the clinical features of taxane therapy in SLC of EC. Methods: The selection criteria were pathologically proven EC; advanced or recurrent disease that had previously been treated with FP at our hospital; performance status 0-2; and adequate organ functions. The FP regimens used included 5-FU or S-1 and cisplatin or nedaplatin. Docetaxel (DTX) was administerd at 70mg/m2 triweekly for 6 weeks with 1 week’s rest. Paclitaxel (PTX) was administered at 100mg/m2 weekly with the same schedule. Overall survival of PTX was compared to DTX with baseline prognostic factors adjusted, using Cox proportional hazard model. Results: The analysis covered 110 patients over the period from August 2006 to June 2012. The median age was 64 years (range 39-83); 97 males and 13 females; 108 squamous cell carcinomas and 2 adenocarcinomas; 34 advanced and 76 recurrent; cStage I/II/III/IV at diagnosis 8/21/49/32; PS 0/1/2 score 20/81/9; DTX treatment 82 patients and PTX treatment 28. Progression-free survival and overall survival were 2.3 & 6.1 months with PTX and 2.8 and 6.9 months with DTX (no significant difference). The response rates were PTX/DTX/Total 11.1%/3.7%/5.5%. Hazard ratio of overall survival between DTX and PTX was 1.054 with adjusted by PS, sex and number of metastasis. The rate of grade 3-4 neutropenia was higher with DTX (28%) than with PTX (7%). Grade 3 febrile neutropenia was seen in 3.7% of DTX-treated patients but in no PTX patients. Grade 2 or more fatigue was seen in 16% of DTX patients and 10% of PTX ones, and grade 2 or more neuropathy was seen in 1.2% of DTX patients and 32% of PTX ones. Conclusions: PTX and DTX were both effective in SLC of EC, but the toxicity profiles of the two regimens differed. In terms of febrile neutropenia or fatigue, PTX seems more appropriate for SLC of EC.
