Abstract Background Expansion of the indication for liver resection and new regimens for systemic chemotherapy have improved postoperative outcomes for synchronous colorectal liver metastases (CRLM). However, such cases can still have a high recurrence rate, even after curative resection. Therefore, there is a need for postoperative adjuvant chemotherapy (POAC) after liver resection in patients with CRLM. There are few studies of the efficacy of POAC with an oxaliplatin-based regimen after simultaneous resection for colorectal cancer and CRLM with curative intent. The goal of the study was to compare POAC with oxaliplatin-based and fluoropyrimidine regimens using propensity score (PS) matching analysis. Methods The subjects were 94 patients who received POAC after simultaneous resection for colorectal cancer and synchronous CRLM, and were enrolled retrospectively. The patients were placed in a L-OHP (+) group (POAC with an oxaliplatin-based regimen, n = 47) and a L-OHP (−) group (POAC with a fluoropyrimidine regimen, n = 47). Recurrence-free (RFS), cancer-specific (CSS), unresectable recurrence-free (URRFS), remnant liver recurrence-free (RLRFS), and extrahepatic recurrence-free (EHRFS) survival were analyzed. Results Before PS matching, the L-OHP (+) and (−) groups had no significant differences in RFS, CSS, URRFS, RLRFS, and EHRFS. Univariate analysis indicated significant differences in age, preoperative serum CEA (≤ 30.0 ng/mL/ > 30.0 ng/mL), differentiation of primary tumor (differentiated/undifferentiated), T classification (T1–3/T4), number of hepatic lesions and maximum diameter of the hepatic lesion between the L-OHP (+) and (−) groups. After PS matching using these confounders, RFS was significantly better among patients in the L-OHP (+) group compared with the L-OHP (−) group (HR 0.40, 95% CI 0.17–0.96, p = 0.04). In addition, there was a trend towards better RLRFS among patients in the L-OHP (+) group compared with the L-OHP (−) group (HR 0.42, 95% CI 0.17–1.02, p = 0.055). However, there were no significant differences in CSS, URRFS and EHRFS between the L-OHP (+) and (−) groups. Conclusions PS matching analysis demonstrated the efficacy of POAC with an oxaliplatin-based regimen in RFS and RLRFS.

788 Background: A number of retrospective studies reported that 5-year survival rate was 30-60% in patients who underwent curative resection of pulmonary metastases (PM) from colorectal cancer (CRC), and PM-CRC resection was recommended in clinical practice. Efficacy of adjuvant chemotherapy after resection of PM remains unclear. Therefore, using a large-scale data obtained from patients who underwent R0 resection of PM in Japan, we investigated it with a propensity score-matching analysis. Methods: We retrospectively collected clinical data of 1237 patients who underwent metastasectomy of PM-CRC at 46 Japanese institutions from 2004 to 2008. Excluding non-curative resection, preoperative chemotherapies, extra-thoratic metastases, complications after surgery, and inadequate data, 530 patients’ data (surgery alone 269 and surgery with adjuvant chemotherapy 261) were used for the matching. Patient backgrounds affecting doctor’s recommendation of adjuvant chemotherapy and including commonly reported prognostic factors were adjusted, using a propensity score-matching method. Primary and secondary endpoints were overall survival (OS) and disease-free survival (DFS), respectively. Results: After the matching with propensity-score, 167 patients for each group were selected. Patient backgrounds were balanced between both groups. Adjuvant chemotherapies were fluorouracil alone (67%), oxaliplatine-containing regimen (24%), irinotecan-containing regimen (7%) and others (2%). There were no significant differences between both groups in OS (HR 0.97, 95%CI 0.64-1.46, p = 0.88) and DFS (HR 0.99, 95%CI 0.75-1.32, p = 0.96). Conclusions: A propensity score-matching analysis did not show a survival benefit of adjuvant chemotherapy after resection of PM in patients with CRC. A large prospective observational study with high quality or randomized clinical trial is needed.

Background/Aim: We investigated the clinical efficacy of inflammation-based indexes in predicting unfavourable relapse-free survival (RFS) in patients with stage II/III colorectal cancer (CRC) receiving oxaliplatin-based adjuvant chemotherapy. Patients and Methods: A retrospective analysis was performed on 45 patients who underwent curative resection for stage II/III CRC followed by oxaliplatin-based adjuvant chemotherapy after 8 weeks. Upon adjuvant chemotherapy initiation, all patients were evaluated for lymphocyte count (LC), neutrophil/lymphocyte ratio (NLR), lymphocyte/monocyte ratio (LMR), platelet/lymphocyte ratio (PLR), modified Glasgow Prognostic Score (mGPS) and prognostic nutritional index (PNI), after which their correlation with relapse was analysed. Results: Univariate analysis identified LC <1,350/mm3, NLR ≥2.03, LMR <5.15, PLR ≥209, mGPS 2, and early discontinuation of chemotherapy within two months as significant risk factors for RFS. Multivariate analysis identified LMR <5.15, PLR > 209 and mGPS 2 as significant independent risk factors for unfavourable RFS. Conclusion: Measurement of LMR, PLR, and mGPS upon adjuvant therapy initiation can be a useful tool for predicting recurrence after curative surgery for stage II/III CRC.

Abstract Adjuvant chemotherapy is the current standard treatment for stage III colorectal cancer after curative resection. However, the prognosis of stage III colorectal cancer is still poor even after curative resection and adjuvant chemotherapy. Several observational studies suggested that the anti-tumor effect of aspirin. Therefore, we planned a randomized double-blind placebo-controlled phase III trial, which commenced in Japan in March 2018, to confirm the superiority of aspirin over placebo added to adjuvant chemotherapy in terms of disease-free survival (DFS) for stage III colorectal cancer patients after curative resection. A total of 880 patients will be accrued from 20 Japanese institutions within 3 years. The primary endpoint is DFS and the secondary endpoints are overall survival, relapse-free survival, relative dose intensity, adverse events, and serious adverse events. This trial has been registered at Japan Registry of Clinical Trials as jRCTs031180009 (https://jrct.niph.go.jp/detail/589).

e15078 Background: IL-6 and YKL-40, markers of inflammation and cancer growth, are high in serum in patients with colorectal cancer (CRC) and associated with shorter overall survival (OS). We hypothesized that preoperative serum IL-6, YKL-40 and CEA are associated with disease free survival (DFS) and OS in patients with metastatic (mCRC) treated with liver resection. Methods: 457 patients (male/female: 267 (58%)/190 (42%), median age 65 [IQR: 58-71]) diagnosed with mCRC who underwent liver resection were included between March 1998 and February 2013. Preoperative serum samples were collected and stored at -80°C until analysis. Serum IL-6 (R&D Systems, UK) and YKL-40 (Quidel, USA) were determined by ELISA. For DFS and OS we estimated crude and adjusted hazard ratios (HR) and corresponding 95% confidence intervals (CIs) with Cox regression for each biomarker separately. The biomarkers were included as log2-transformed continuous variables and adjustment included mutual adjustment between the biomarkers in addition to adjusting for sex and age. Results: The median (IQR) preoperative biomarker levels were: IL-6 (3.5 pg/ml, 2.1-6.1), YKL-40 (75 ng/ml, 48-127) and CEA (5.2 kU/L, 2.6-18.8). Univariate analysis showed that high serum IL-6 and YKL-40 were associated with shorter DFS (IL-6: HR = 1.18, 1.06-1.31, p < 0.01; YKL-40: HR = 1.19, 1.08-1.32, p < 0.01). Serum CEA was not (p = 0.80). Multivariate analysis (all biomarkers) showed that high IL-6 was associated with shorter DFS (HR = 1.15, 1.02-1.29, p = 0.02), whereas YKL-40 (p = 0.08) and CEA (p = 0.51) were not. Univariate analysis showed that high preoperative serum IL-6 and YKL-40 were associated with shorter OS (IL-6: HR = 1.16, 1.03-1.29, p = 0.01; YKL-40: HR = 1.27, 1.14-1.42, p < 0.01). Serum CEA was not associated with OS (p = 0.16). Multivariate analysis (all biomarkers) showed that high YKL-40 was associated with shorter OS (HR = 1.19, 1.05-1.34, p = 0.01), whereas IL-6 (p = 0.25) and CEA (p = 0.26) were not. Patients with elevated serum levels of all 3 biomarkers had the shortest OS (HR = 2.12; 1.29-3.50, p < 0.01). Conclusions: Serum IL-6 and YKL-40 determined before liver resection may be valuable prognostic biomarkers in patients with metastatic CRC.

780 Background: Recent advances in systemic chemotherapy, including molecular target agents, can introduce “Conversion surgery” and achieve R0 resection even for initially unresectable colorectal liver metastasis (CRLM). We investigated the optimal indication for initial surgical induction and treatment strategy for unresectable CRLM. Methods: Our current surgical indication for CRLM as follows: i) curative resection is achievable, ii) no limitation of tumor size and number, and iii) future remnant liver volume over 35%. Additionally, same indication is applied even after chemotherapy.Two hundreds forty-one cases from 1994 to 2015, consisted of 134 initially resectable case and 107 unresectable cases, were included. Among 107 unresectable cases, 55 cases received current chemotherapy such as FOLFOX, FOLFILI, XEROX and FOLFOXIRI. Results: 1) Optimal indication for initially resectable case:Multivariate analysis revealed MDN (Maximum Diameter × Number) index more than 30 of metastatic liver tumor (HR3.06), non-curative resection of metastatic liver tumor (HR4.082) and poor differentiation of primary tumor (HR11.14).2) Treatment strategy of unresectable case for “Conversion surgery” (FOLFOXIRI vs. other regimen): Forty-two unresectable cases with MDN > 30 were included. Of those 14 cases, FOLFOXIRI regimen was applied. Regarding clinicopathological factors, the use of molecular targeted drug was introduced in all patients of FOLFOXIRI group, but 67.9% patients of other regimen group. The “Conversion” rate in FOLFIXIRI group and other regimen group were 64.3% and 39.3% (p = 0.126), and median period until “Conversion” were 6.2 courses and 11.8 courses (p = 0.038). Regarding tumor necrotic rate, FOLFOXIRI regimen induced higher necrotic rate than other regimen group (77.9% vs. 50.4%, p = 0.073). Overall survival in FOLFOXIRI group has been better than that in other regimen group and 3-years survival rates were 83.3% and 48.0% (p = 0.044). Also, relapse free survival in FOLFOXIRI group was significantly better than that in other regimen group (p = 0.002). Conclusions: MDN can predict surgical outcome for CRLM. FOLFOXIRI plus molecular target drug may be a promising option for CRLM with MDN > 30.
