570 Background: The significance of vascular emboli (VE) in stage III colorectal cancer (CRC), the mechanism of their formation and their therapy strategy remain obscure demanding enhanced research. Methods: Data from 323 consecutive patients (192 non-VE, 131 VE) receiving radical surgery and adjuvant chemotherapy in our institution between Jan. 2009 and Nov. 2014 were retrospectively collected. The follow-up deadline was Feb. 2016. Potential prognostic risk factors were tested using univariate and multivariate survival analyses. mRNAs differentially expressed between VE and non-VE stage III CRC were analyzed using Agilent Gene Expression oligo-microarrays (Version 6.5). Patient-derived xenograft (PDX) nude mouse models were constructed to evaluate the efficacy of adjuvant chemotherapy plus targeted drugs (cetuximab or bevacizumab) on VE and non-VE stage III CRC. Results: VE was significantly associated with gross tumor morphology (p = 0.001), histologic type (p < 0.001), lymph node status (p < 0.001), sub-class of stage III (p =0.001), and serum CA199 level (p = 0.022). VE and lymph node status were independent risk factors for overall survival (OS) (p < 0.001, p = 0.008) and disease-free survival (DFS) (p < 0.001, p = 0.007). The median OS and DFS in VE stage III CRC patients were 38 months and 24 months, respectively. Compared with pericarcinous tissue, 809 genes (396 up-, 413 down-regulated) were differently expressed in no-VE tissue, and 1513 genes (898 up-, 615 down-regulated) in VE tissue. The top ten up-regulated protein-coding genes in VE stage III CRC were ITGBL1 (p<0.001), PROCR (p<0.001), CENPW (p<0.001), ZNF485 (p<0.001), VEGFA (p<0.001), DSG3 (p<0.001), CYP24A1 (p=0.001), COL10A1 (p=0.001), HIST3H2A (p=0.001)and PSAT1 (p=0.002). Conclusions: VE appears to be an independent risk factor for the prognosis of stage III CRC patients treated with radical surgery and adjuvant chemotherapy. Differently regulated genes seem to be involved in the formation and progress of VE. The therapy scheme should be more individualized taking into account the VE status.

Background This study aimed to retrospectively investigate the efficacy and tolerability of adjuvant chemotherapy in ≥70-year-old patients with stage IIA (T3N0M0) colorectal cancer. Methods Lymphovascular invasion, perineural invasion, margin positivity, dissected lymph node count of <12, and presence of perforation/obstruction were accepted as risk factors. Those patients with at least one risk factor were regarded as having high risk. Results The study included 168 patients, among which 95 (56.5%) were male and 73 (43.5%) were female. The median age of patients was 73 years (range: 70–94). One hundred one (60.1%) patients were identified to have high risk. Eighty-one (87%) patients received 5-flourouracil+leucovorin and 12 (13%) patients received capecitabine regimens as adjuvant chemotherapy. The patients receiving capecitabine regimen had significantly higher rates of dose reduction at initiation and during the treatment. Among low-risk group, there was no statistically significant difference between patients with and without adjuvant chemotherapy in terms of disease-free survival or overall survival (p = 0.528 and p = 0.217, respectively). In high-risk group, patients receiving adjuvant chemotherapy significantly differed from those not receiving adjuvant chemotherapy in terms of median disease-free survival and overall survival (p = 0.009 and p < 0.001, respectively). While the grade, lymph node status, and adjuvant chemotherapy were identified as the most significant independent factors for disease-free survival, the most significant factors for overall survival were the age, Eastern Cooperative Oncology Group performance status, adjuvant chemotherapy, and recurrence. Conclusion The findings of our study showed improved disease-free survival and overall survival in high-risk ≥70-year-old patients who received adjuvant chemotherapy due to T3N0M0 colorectal cancer. We believe that 5-flourouracil+leucovorin or capecitabine regimens should be recommended for these older high-risk patients who could receive adjuvant chemotherapy regardless of age.

Background. Lymph node status of clinical T1 (diameter≤3 cm) lung cancer largely affects the treatment strategies in the clinic. In order to assess lymph node status before operation, we aim to develop a noninvasive predictive model using preoperative clinical information. Methods. We retrospectively reviewed 924 patients (development group) and 380 patients (validation group) of clinical T1 lung cancer. Univariate analysis followed by polytomous logistic regression was performed to estimate different risk factors of lymph node metastasis between N1 and N2 diseases. A predictive model of N2 metastasis was established with dichotomous logistic regression, externally validated and compared with previous models. Results. Consolidation size and clinical N stage based on CT were two common independent risk factors for both N1 and N2 metastases, with different odds ratios. For N2 metastasis, we identified five independent predictors by dichotomous logistic regression: peripheral location, larger consolidation size, lymph node enlargement on CT, no smoking history, and higher levels of serum CEA. The model showed good calibration and discrimination ability in the development data, with the reasonable Hosmer-Lemeshow test (p=0.839) and the area under the ROC being 0.931 (95% CI: 0.906-0.955). When externally validated, the model showed a great negative predictive value of 97.6% and the AUC of our model was better than other models. Conclusion. In this study, we analyzed risk factors for both N1 and N2 metastases and built a predictive model to evaluate possibilities of N2 metastasis of clinical T1 lung cancers before the surgery. Our model will help to select patients with low probability of N2 metastasis and assist in clinical decision to further management.

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).

638 Background: In previous phase III studies (MOSAIC and XELOXA trial), oxaliplatin based chemotherapy was shown to be a standard adjuvant treatment for stage III colorectal cancer (CRC). However, its efficacy for curatively resected stage IV CRC has not yet been clarified. In this retrospective study, we evaluate the efficacy of oxaliplatin based chemotherapy in adjuvant setting for curatively resected stage IV CRC. Methods: Eighty-three patients received adjuvant chemotherapy after R0 resection for Stage IV CRC in our institute between Mar 2007 and Feb 2013. Progression-free survival (PFS), overall survival (OS), completion rate of the treatment and safety were evaluated. Median follow-up time was 33.3 months. Results: Baseline characteristics were as follows (N=83): median age, 61; male/female, 46/37; ECOG PS0, all; colon/rectum, 54/29; synchronous/asynchronous, 41/42. Metastatic sites were liver in 46, lung in 11, peritoneum in 13, lymph node in 12 patients. Median PFS and OS were not reached. Three-year PFS and OS were 67.8% and 88.2%, respectively. Completion rate was 78.6% of the patients. In univariate analysis, completion of treatment, synchronous development and metastasis limited to lung were associated with better PFS, though not statistically significant. Confirmed regional lymph node metastasis of primary tumor showed a trend toward to concern with poor OS. Differences in metastatic site were not observed in both PFS and OS. Multivariate analysis revealed none as a significant prognostic factor. Conclusions: Compared the results to previous trial for stage III CRC, oxaliplatin based adjuvant chemotherapy for stage IV CRC after R0 resection was demonstrated to be consistent in tolerability and efficacy.
