499 Background: The type, abundance, and location of tumor-infiltrating lymphocytes (TILs) have been associated with prognosis in colorectal cancer. The objective of this study was to assess the prognostic role of TILs and develop a nomogram for accurate prognostication of stage II colorectal cancer. Methods: Immunohistochemistry was conducted to assess the densities of intraepithelial and stromal CD3+, CD8+, CD45RO+ and FOXP3+ TILs, and to estimate PD-L1 expression in tumor cells for 168 patients with stage II colorectal cancer. The prognostic roles of these features were evaluated using COX regression model, and nomograms were established to stratify patients into low and high-risk groups and compare the benefit from adjuvant chemotherapy. Results: In univariate analysis, patients with high intraepithelial or stromal CD3+, CD8+, CD45RO+ and FOXP3+ TILs were associated significantly with better relapse-free survival (RFS) and overall survival (OS), except for stromal CD45RO+ TILs, whereas PD-L1 expression wasn't associated with RFS or OS. In multivariate analysis, patients with high intraepithelial CD3+ and stromal FOXP3+ TILs were associated with better RFS (p < 0.001 and p = 0.032, respectively), while only stromal FOXP3+ TILs was an independent prognostic factor for OS (p = 0.031). The nomograms were well calibrated and showed a c-index of 0.751 and 0.757 for RFS and OS, respectively. After stratifying into low and high-risk groups, the high-risk group exhibited a better OS from adjuvant chemotherapy (3-year OS of 81.9% v 34.3%, p = 0.006). Conclusions: These results may help improve the prognostication of stage II colorectal cancer and identify a high-risk subset of patients who appeared to benefit from adjuvant chemotherapy.

TPS3621 Background: Adjuvant chemotherapy for stage II colorectal cancer (CRC) still remains controversial. Although the NCCN and ESMO guidelines recommend adjuvant chemotherapy for patients with “high-risk features,” the survival benefit has not been confirmed. We reviewed the evidence levels for prognostic values of risk factors, because lack of their robustness is a major source of uncertainty regarding the optimal indication of adjuvant chemotherapy. Consequently, on top of the T-stage, three pathological factors—perineural invasion (Pn), tumor budding (BD), and desmoplastic reaction (DR)—were selected as robust risk factors of recurrence. Among the conventional factors, the prognostic value of Pn had been well validated in a multicenter study conducted by the Japanese Society for Cancer of the Colon and Rectum (JSCCR; Am J Surg Path 2013), but others were deemed suboptimal in terms of the prognostic value. BD and DR are novel tumor- and stroma-factors, respectively, associated with cancer microenvironment at the tumor front. According to the JSCCR and ITBCC 2016 criteria, tumors are graded as BD1, BD2, or BD3. The DR heterogeneity is categorized into Mature, Intermediate, and Immature patterns based on site-specific products of cancer-associated fibroblasts—keloid-like collagen and myxoid stroma. According to a recent prospective multicenter study, BD and DR characterization represent a higher level of prognostic value than other conventional factors (SACURA trial; J Clin Oncol 2019, Br J Cancer 2021). Based on the four selected risk factors, we can exclude the patient group with favorable prognosis (i.e., > 90% of 5-year RFS), which accounts for approximately 40% of the total population, resulting in enabling us to identify the concentrated population of high risk of developing recurrence. Methods: The Japan Clinical Oncology Group (JCOG) launched a randomized controlled phase III trial to evaluate the superiority of adjuvant chemotherapy in terms of relapse-free survival (RFS) over observation only in stage II CRC patients aged 20–80 years having one or more of the following risk factors: pathological T4, Pn, BD3, and non-Mature DR. Patients are randomised, in a 1:1:1 ratio, to [A] observation, [B] capecitabine monotherapy for 6 months, or [C] capecitabine and oxaliplatin (CAPOX) for 3 months. A total of 1680 patients will be accrued from 54 Japanese institutions assuming 3-year RFS with [A] to be 82% and expected 5% increase in 3-year RFS for [B] and [C] with one-sided alpha of 2.5% and power of 80% for each pair comparison. Patient enrollment was started in January 2020 and 170 patients have been enrolled until January 2021. This trial has been registered at Japan Registry of Clinical Trials as jRCTs031190186. Clinical trial information: jRCTs031190186.

GADD45B acts as a member of the growth arrest DNA damage-inducible gene family, which has demonstrated to play critical roles in DNA damage repair, cell growth, and apoptosis. This study aimed to explore the potential relationship between GADD45B expression and tumor progression and evaluate the clinical value of GADD45B in stage II colorectal cancer (CRC). The expression patterns and prognostic value of GADD45B in CRC were analyzed based on The Cancer Genomic Atlas (TCGA). GADD45B expression features of 306 patients with stage II CRC and 201 patients with liver metastasis of CRC were investigated using immunochemical staining on tissue microarrays. Afterward, survival analysis and stratification analysis were performed in stage II to explore the prognostic and predictive significance of GADD45B. Overexpressed GADD45B is associated with poorer prognosis for CRC patients both in overall survival (OS) (p < 0.001) and disease-free survival (DFS) (p = 0.001) based on the TCGA database. Analysis results according to the stage II CRC cohort and the liver metastatic CRC cohort revealed that GADD45B was gradually upregulated in normal mucosa including primary colorectal cancer (PCC). Colorectal liver metastases (CLM) tissues were arranged in order (normal tissue vs. PCC p = 0.005 and PCC vs. CLM p = 0.001). The low GADD45B group had a significantly longer five-year OS (p = 0.001) and progression-free survival (PFS) (p < 0.001) than the high GADD45B group for the stage II patients. The multivariate Cox regression analysis results proved that the expression level of GADD45B was an independent prognostic factor for stage II after radical surgery (OS: Hazard Ratio (HR) 0.479, [95% confidence interval (CI) 0.305–0.753] and PFS:HR 0.490, [95% CI 0.336–0.714]). In high GADD45B expression subgroup of stage II cohort, the patients who underwent adjuvant chemotherapy had longer PFS than those who did not (p = 0.008). High expression levels of GADD45B is an independent prognostic factor of decreased OS and PFS in stage II CRC patients. The stage II CRC patients with high GADD45B expression might benefit from adjuvant chemotherapy.
