Patients with stage III colonic adenocarcinoma have a spectrum of risk for recurrent disease, and histopathological variables that predict recurrence can help stratify patients into prognostic groups. To identify histopathological predictors of recurrence, we investigated the effect of implementation of the eighth edition of the American Joint Committee on Cancer (AJCC8) staging system definition of tumor deposits and International Tumor Budding Consensus Conference (ITBCC) criteria for tumor budding compared with other known prognostic variables in 256 resected colonic adenocarcinomas, including 150 stage III and 106 stage II tumors. In stage III colon cancer, tumor deposits and high tumor budding were the only independent histological variables that predicted disease recurrence. In a multivariable analysis in stage III colon cancer, tumor deposits and high tumor budding were associated with a 2.2- and 1.5-fold increased risk of developing disease recurrence, respectively (95% CI = 1.1-4,2, P = .02, and 95% CI = 1.1-2.1, P = .01, respectively). The negative prognostic effect of tumor deposits was most pronounced in patients with stage IIIB disease in which tumor deposits were associated with a 3.2-fold increased risk of disease recurrence (95% CI = 1.4-7.1; P = .005). Within the N1 cohort, patients with tumor deposits without concurrent positive lymph nodes (N1c) had a significantly decreased disease-free survival compared with patients with N0 tumors ( P < .001) and patients with N1a/b tumors ( P = .02). As independent risk factors for recurrence, tumor deposits and high tumor budding are important histopathological variables and should be included as a part of a routine comprehensive pathological risk assessment in stage III colon cancer.

3525 Background: Microsatellite instable/deficient mismatch repair (MSI) metastatic colorectal cancers have been reported to be of poor prognosis. The interaction between MSI and BRAFV600E mutation complicates the picture. Methods: Patients with resected stage III CC from 7 studies with disease recurrence and data available for MSI and BRAFV600E status were analyzed. The primary endpoint was survival after recurrence (SAR) to assess the prognostic roles of MSI and BRAFV600E, respectively. Associations of markers with SAR were analyzed using Cox proportional hazards models adjusted for clinicopathologic features (data collected 12/1998 to 11/2009). Results: Among 2630 patients with cancer recurrence (1491 men [56.7%], mean age, 58.5 [19-85] years), multivariable analysis revealed that patients with MSI tumors (n = 220) had significantly better SAR (adjusted hazard ratio [aHR], 0.82; 95% CI, 0.69-0.98; P = .029) than patients with microsatellite stable /proficient MMR (MSS) tumors (n = 1766). This was also observed when looking at patients treated by the standard FOLFOX adjuvant regimen only (aHR, 0.76; 0.58-1.00; P = .048). Same trends were observed when looking at MSI/dMMR patients outcome in BRAFV600E wild-type (aHR, 0.84; P = .10) and mutant (aHR, 0.88; P = .43) subgroups separately, without reaching statistical significance. As previously described poor SAR was observed in BRAFV600E mutants vs wild type patients (n = 244; aHR, 2.06; 95% CI, 1.73-2.46; P < .0001) and this was also true in BRAFV600E mutants MSI/dMMR patients (n = 77, aHR, 2.65 ; 95% CI, 1.67-4.21; p < .0001). Other factors associated with a poor SAR were : olderage, male gender, T4/N2, proximal primary tumor location, poorly differentiated adenocarcinoma, and early recurrence (by 1y increase). Conclusions: In stage III colon cancer patients recurring after adjuvant chemotherapy and before the era of immuno-oncologic agents, MSI/dMMR was associated with a better survival compared to MSS. BRAFV600E mutation seems to be a poor prognostic factor for both MSI/dMMR and MSS/pMMR patients.

3519 Background: Tumor deposits (TDs) are isolated tumor foci in the pericolic, perirectal or mesocolic fat without residual lymph node (LN) tissue. TDs seem to impact the prognosis of stage III colon cancer (CC) patients (pts) but are only considered in TNM staging in the absence of LN metastases (LNM). We aimed at evaluating the prognosis value for disease free survival (DFS)of TDs in International Duration Evaluation of Adjuvant Chemotherapy (IDEA) France phase III study (NCT00958737) that compared 3 versus 6 months of adjuvant FOLFOX or CAPOX for stage III CC pts. Methods: All pathological reports of pts included in IDEA France trial were retrospectively analyzed. DFS according to the presence or absence of TDs was evaluated using Kaplan-Meier estimator. Multivariable Cox model analysis was performed to evaluate the association between TDs and DFS. This analysis did not included immunohistochemical biomarkers. Results: Among the 2022 pts included in IDEA France study, 1942 (96%) were analyzed. 80 pts were excluded: no pathological report (n = 68), pts without treatment (n = 12). TDs were found in 184 pts (9.47%), of whom 74 with N1a/b (40%), 55 with N1c (30%) and 55 with N2 LN stage (30%). All characteristics were similar according to the presence of TDs, except for tumor/node (TN) stage (T4 and/or N2 are more frequent in pts with TDs; p = .0046). The 3-year DFS rates were 65.59% [95% confidence interval (95%CI) 58.04-72.12] and 74.71% [95%CI 72.57-76.71] for pts with and without TDs, respectively (p = 0.0079). In multivariable analysis, TDs were associated with higher risk of recurrence or death (hazard ratio (HR) = 1.36, 95%CI 1.05-1.75, p = .0201), as well as T4 and/or N2 (HR = 2.21, 95%CI 1.03-1.59, p < .001), 3 months of adjuvant treatment (HR = 1.29, 95%CI 1.09-1.52, p = .0029), obstruction (HR = 1.28, 95%CI 1.03-1.59, p = .0233) and male (HR = 1.24, 95%CI 1.04-1.46, p = .0151). Adding TDs count to the LNM count, 35 out of 1454 N1a/b/c CC pts (2.4%) were reclassified as N2 and experienced worse 3 years DFS than confirmed N1 CC pts (p = .0151). Conclusions: TD is an independent and valuable prognostic factor for DFSin stage III CC pts and should be considered whatever the LNM status.

PURPOSE The purpose of this study was to evaluate the prognostic value of Immunoscore in patients with stage III colon cancer (CC) and to analyze its association with the effect of chemotherapy on time to recurrence (TTR). METHODS An international study led by the Society for Immunotherapy of Cancer evaluated the predefined consensus Immunoscore in 763 patients with American Joint Committee on Cancer/Union for International Cancer Control TNM stage III CC from cohort 1 (Canada/United States) and cohort 2 (Europe/Asia). CD3+ and cytotoxic CD8+ T lymphocyte densities were quantified in the tumor and invasive margin by digital pathology. The primary end point was TTR. Secondary end points were overall survival (OS), disease-free survival (DFS), prognosis in microsatellite stable (MSS) status, and predictive value of efficacy of chemotherapy. RESULTS Patients with a high Immunoscore presented with the lowest risk of recurrence, in both cohorts. Recurrence-free rates at 3 years were 56.9% (95% CI, 50.3% to 64.4%), 65.9% (95% CI, 60.8% to 71.4%), and 76.4% (95% CI, 69.3% to 84.3%) in patients with low, intermediate, and high immunoscores, respectively (hazard ratio [HR; high v low], 0.48; 95% CI, 0.32 to 0.71; P = .0003). Patients with high Immunoscore showed significant association with prolonged TTR, OS, and DFS (all P < .001). In Cox multivariable analysis stratified by participating center, Immunoscore association with TTR was independent (HR [high v low], 0.41; 95% CI, 0.25 to 0.67; P = .0003) of patient’s sex, T stage, N stage, sidedness, and microsatellite instability status. Significant association of a high Immunoscore with prolonged TTR was also found among MSS patients (HR [high v low], 0.36; 95% CI, 0.21 to 0.62; P = .0003). Immunoscore had the strongest contribution χ2 proportion for influencing survival (TTR and OS). Chemotherapy was significantly associated with survival in the high-Immunoscore group for both low-risk (HR [chemotherapy v no chemotherapy], 0.42; 95% CI, 0.25 to 0.71; P = .0011) and high-risk (HR [chemotherapy v no chemotherapy], 0.5; 95% CI, 0.33 to 0.77; P = .0015) patients, in contrast to the low-Immunoscore group ( P > .12). CONCLUSION This study shows that a high Immunoscore significantly associated with prolonged survival in stage III CC. Our findings suggest that patients with a high Immunoscore will benefit the most from chemotherapy in terms of recurrence risk.

Abstract Background The American Joint Committee on Cancer staging and other prognostic tools fail to account for stage-independent variability in outcome. We developed a prognostic classifier adding Immunoscore to clinicopathological and molecular features in patients with stage III colon cancer. Methods Patient (n = 559) data from the FOLFOX arm of adjuvant trial NCCTG N0147 were used to construct Cox models for predicting disease-free survival (DFS). Variables included age, sex, T stage, positive lymph nodes (+LNs), N stage, performance status, histologic grade, sidedness, KRAS/BRAF, mismatch repair, and Immunoscore (CD3+, CD8+ T-cell densities). After determining optimal functional form (continuous or categorical) and within Cox models, backward selection was performed to analyze all variables as candidate predictors. All statistical tests were two-sided. Results Poorer DFS was found for tumors that were T4 vs T3 (hazard ratio [HR] = 1.76, 95% confidence interval [CI] = 1.19 to 2.60; P = .004), right- vs left-sided (HR = 1.52, 95% CI = 1.14 to 2.04; P = .005), BRAF V600E (HR = 1.74, 95% CI = 1.26 to 2.40; P &lt; .001), mutant KRAS (HR = 1.66, 95% CI = 1.08 to 2.55; P = .02), and low vs high Immunoscore (HR = 1.69, 95% CI = 1.22 to 2.33; P = .001) (all P &lt; .02). Increasing numbers of +LNs and lower continuous Immunoscore were associated with poorer DFS that achieved significance (both Ps&lt; .0001). After number of +LNs, T stage, and BRAF/KRAS, Immunoscore was the most informative predictor of DFS shown multivariately. Among T1–3 N1 tumors, Immunoscore was the only variable associated with DFS that achieved statistical significance. A nomogram was generated to determine the likelihood of being recurrence-free at 3 years. Conclusions The Immunoscore can enhance the accuracy of survival prediction among patients with stage III colon cancer.

Purpose Reduction of adjuvant treatment duration may decrease toxicities without loss of efficacy in stage III colon cancer. This could offer clear advantages to patients and health care providers. Methods In International Duration Evaluation of Adjuvant Chemotherapy (IDEA) France, as part of the IDEA international collaboration, patient with colon cancer patients were randomly assigned to 3 and 6 months of modified FOLFOX6 (mFOLFOX6: infusional fluorouracil, leucovorin, and oxaliplatin) or capecitabine plus oxaliplatin (CAPOX) by physician choice. The primary end point was disease-free survival (DFS), and analyses were descriptive. Results A total of 2,010 eligible patients received either 3 or 6 months of chemotherapy (modified intention-to-treat population); 2,000 (99%) had stage III colon cancer (N1: 75%, N2: 25%); 1,809 (90%) received mFOLFOX6, and 201 (10%) received CAPOX. The median age was 64 years, and the median follow-up time was 4.3 years. Overall, 94% (3 months) and 78% (6 months) of patients completed treatment (fluoropyrimidines ± oxaliplatin). Maximal grade 2 and 3 neuropathy rates were 28% and 8% in the 3-month arm and 41% and 25% in the 6-month arm ( P < .001). Final rates of residual neuropathy greater than grade 1 were 3% in the 3-month arm and 7% in the 6-month arm ( P < .001). There were 578 DFS events: 314 and 264 in the 3- and 6-month arms, respectively. The 3-year DFS rates were 72% and 76% in the 3- and 6-month arms, respectively (hazard ratio [HR], 1.24; 95% CI, 1.05 to 1.46; P = .0112). In the 3 and 6-month arms, respectively, for patients who received mFOLFOX6, the 3-year DFS rates were 72% and 76% (HR, 1.27; 95% CI, 1.07 to 1.51); for the T4 and/or N2 population, they were 58% and 66% (HR, 1.44; 95% CI, 1.14 to 1.82); and for the T1-3N1 population, they were 81% and 83% (HR, 1.15; 95% CI, 0.89 to 1.49). Conclusion IDEA France, in which 90% of patients received mFOLFOX6, shows superiority of 6 months of adjuvant chemotherapy compared with 3 months, especially in the T4 and/or N2 subgroups. These results should be considered alongside the international IDEA collaboration data.

PURPOSE To develop recommendations for duration of adjuvant chemotherapy with a fluoropyrimidine and oxaliplatin for patients with completely resected stage III colon cancer based on the results of trials of 3 months compared with 6 months of treatment. METHODS ASCO convened an Expert Panel and conducted a systematic review of relevant studies. The guideline recommendations were based on the review of evidence by the Expert Panel. RESULTS Pooled data from the six International Duration Evaluation of Adjuvant Chemotherapy (IDEA) Collaboration randomized controlled trials comprise the evidence base for these guideline recommendations. RECOMMENDATIONS The recommendations for therapy duration apply to patients with completely resected stage III colon cancer who are being offered adjuvant chemotherapy with oxaliplatin and a fluoropyrimidine. Recommendations are informed by the findings of a recent pooled analysis of clinical trials that compared 6 months versus 3 months of oxaliplatin-based chemotherapy. For patients at a high risk of recurrence (T4 and/or N2), adjuvant chemotherapy should be offered for a duration of 6 months. For patients at a low risk of recurrence (T1, T2, or T3 and N1), either 6 months of adjuvant chemotherapy or a shorter duration of 3 months may be offered on the basis of a potential reduction in adverse events and no significant difference in disease-free survival with the 3-month regimen. In determining duration of therapy, the Expert Panel recommends a shared decision-making approach, taking into account patient characteristics, values and preferences, and other factors and including a discussion of the potential for benefit and risks of harm associated with treatment duration.

4004 Background: Despite recent advances in the treatment of metastatic colorectal cancer, tailoring adjuvant treatment of stage II and III colon cancer patients remains controversial. Identifying a reliable panel of prognostic and predictive markers for tumor recurrence is critical in selecting an individualized and tailored chemotherapy. Tumor angiogenesis plays an important role in tumor development, progression and metastasis. In this retrospective study, we tested whether a specific pattern of 40 functionally significant polymorphisms in 37 genes involved in angiogenesis and tumor microenvironment will predict the risk of tumor recurrence in stage II and III colon cancer patients treated with adjuvant chemotherapy. Methods: Between 1999 and 2006 blood specimens from 140 patients (69 females and 71 males with a median age of 59 years; range=28–86) were obtained at the University of Southern California/Norris Comprehensive Cancer Center (USC/NCCC). Sixty-three patients had stage II and 77 had stage III colon cancer. The median follow-up was 5.4 years (range=2.0–16.8). 51 of 140 patients (36.4%) developed tumor recurrence with a 5-year probability of 0.28 ± 0.06 for stage II and 0.40 ± 0.06 for stage III colon cancer patients. Genomic DNA was extracted from peripheral blood and genotypes were determined using PCR based RFLP. Results: Polymorphisms in VEGF (C936T; p=0.009, log-rank) and VEGFR2 (+4422 AC- repeat; p=0.04, log-rank and +1416 T/A; p=0.0009, log-rank) were associated with risk of tumor recurrence in stage III colon cancer patients (n=77). VEGFR2 AC-repeat polymorphisms were additionally associated with risk of recurrence in Stage II colon cancer patients (n=63, p=0.02, log-rank). Conclusion: VEGF C936T and VEGFR2 (+4422 AC-repeat and +1416 T/A) polymorphisms may help to identify Stage II and III colon cancer patients who are at increased risk for developing tumor recurrence. Angiogenesis seems to play a crucial role in tumor recurrence, thus targeting VEGF and VEGFR2 may be of clinical benefit for stage II and stage III colon cancer patients. Large prospective trials are needed to validate these preliminary data. No significant financial relationships to disclose.
