620 Background: For stage II colon cancer, the effect of postoperative adjuvant chemotherapy is still controversial. It is well known that tumor-associated macrophages (TAMs) play an important role in tumor progression. The aim of this study is to determine the effect of TAMs as predictor for adjuvant chemotherapy for stage II colon cancer. Methods: From July 2009 to June 2012, 521 patients with pathological stage II colon cancer were included. TAMs were detected using tissue microarray and immunohistochemistry (all TAMs detected by CD68; M2 subtype detected by CD206). The density of CD68+ TAMs, CD206+ TAMs and the ratio of CD206+ TAMs / CD68+ TAMs (CD206 / CD68 ratio) were calculated. The cut-off values were defined using X-Tile software. Results: High CD206+ TAMs density and high CD206 / CD68 ratio were significantly associated with reduced disease-free survival (DFS, P < 0.001 and P < 0.001, respectively) and overall survival (OS, P < 0.001 and P < 0.001, respectively). And CD206 / CD68 ratio had a better prognostic power. Furthermore, for patients with low CD206 / CD68 ratio, adjuvant chemotherapy made no benefit. But for high CD206 / CD68 ratio, adjuvant chemotherapy significantly improved DFS and OS (as shown in Table 1). In subgroup analysis, for T3 with high-risk factors or T4 tumors, CD206 / CD68 ratio was also a significant predictor for adjuvant chemotherapy (interaction P = 0.024 in DFS). Conclusions: For stage II colon cancer, CD206 / CD68 ratio was a good prognostic and predictive biomarker for adjuvant chemotherapy. Together with clinicopathological high-risk factors, it might facilitate patient counselling and individualise management. [Table: see text]

Abstract To identify risk factors for recurrence in patients with stage II colon cancer, Cox proportional hazards regression analysis was performed in 194 patients with stage II colon cancer who underwent curative surgery between April 1997 and December 2008. Thirteen clinical and pathologic factors, including use of fluoropyrimidine-based adjuvant chemotherapy in 113 of the patients (58.2%), were assessed. By multivariate analysis, only obstruction, perforation, and T4-level invasion were identified as independent risk factors affecting disease-free survival (DFS) (P &lt; 0.01). The 5-year DFS rate was 70.6% in patients with one or more risk factors (n = 68) and 96.0% in patients with no risk factors (n = 126) (P &lt; 0.01). These results suggest that obstruction, perforation, and T4-level invasion are suitable candidates for prediction of tumor recurrence in patients with stage II colon cancer. The oxaliplatin-based adjuvant chemotherapy, which has been reported to be effective in stage III colon cancer patients, may improve the prognosis in high-risk stage II colon cancer patients.

PURPOSE To develop recommendations for adjuvant therapy for patients with resected stage II colon cancer. METHODS ASCO convened an Expert Panel to conduct a systematic review of relevant studies and develop recommendations for clinical practice. RESULTS Twenty-one observational studies and six randomized controlled trials met the systematic review inclusion criteria. RECOMMENDATIONS Adjuvant chemotherapy (ACT) is not routinely recommended for patients with stage II colon cancer who are not in a high-risk subgroup. Patients with T4 tumors are at higher risk of recurrence and should be offered ACT, whereas patients with other high-risk factors, including sampling of fewer than 12 lymph nodes in the surgical specimen, perineural or lymphatic invasion, poorly or undifferentiated tumor grade, intestinal obstruction, tumor perforation, or grade BD3 tumor budding, may be offered ACT. The addition of oxaliplatin to fluoropyrimidine-based ACT is not routinely recommended, but may be offered as a result of shared decision making. Patients with mismatch repair deficiency/microsatellite instability tumors should not be routinely offered ACT; if the combination of mismatch repair deficiency/microsatellite instability and high-risk factors results in a decision to offer ACT, oxaliplatin-containing chemotherapy is recommended. Duration of oxaliplatin-containing chemotherapy is also addressed, with recommendations for 3 or 6 months of treatment with capecitabine and oxaliplatin or fluorouracil, leucovorin, and oxaliplatin, with decision making informed by key evidence of 5-year disease-free survival in each treatment subgroup and the rate of adverse events, including peripheral neuropathy.
