| Abstract |
Profound methylation of CpG islands constitutes a distinct molecular subtype of colorectal cancer (CRC). The frequencies of methylation in CRC vary according to clinico-pathological characteristics including sex. However, interaction between these characteristics and prognostic influence of methylation status has not been clearly defined. We have investigated the prognostic role of promoter methylation using eight CpG island methylator phenotype (CIMP) markers in 497 stage II or III CRC patients who underwent curative resection followed by adjuvant FOLFOX. Overall survival (OS) and disease-free survival (DFS) were compared between subgroups classified by methylation status, and interactions with clinico-pathological features were analyzed. CIMP-high (≥5 methylated loci) and concurrent methylation in NEUROG1 and CDKN2A (p16) were found in 5.8 and 7.9 % of patients, respectively. Although CIMP-high status was not associated with survival, concurrent methylation in NEUROG1 and CDKN2A (p16) was associated with shorter OS and DFS. Moreover, the prognostic role of the concurrent methylation was different among sex. The negative prognostic impact was only observed in male but not in female (interaction p value = 0.026 for OS and 0.011 for DFS). In male, the 5-year OS was 61.6 % in concurrent methylation (+) and 91.7 % in concurrent methylation (-) (p < 0.001) whereas it was 95.0 and 92.8 % in female, respectively (p = 0.78). Concurrent methylation in NEUROG1 and CDKN2A is associated with poor survival in CRC treated with adjuvant FOLFOX. Interaction analysis indicates that the prognostic role is different according to sex. |

Attention Score in Context
This research output has an Altmetric Attention Score of 2. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 09 July 2015.
All research outputs
#13,441,654
of 22,816,807 outputs
Outputs from Clinical Epigenetics
#671
of 1,256 outputs
Outputs of similar age
#123,350
of 262,224 outputs
Outputs of similar age from Clinical Epigenetics
#26
of 33 outputs
Altmetric has tracked 22,816,807 research outputs across all sources so far. This one is in the 39th percentile – i.e., 39% of other outputs scored the same or lower than it.
So far Altmetric has tracked 1,256 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 6.5. This one is in the 44th percentile – i.e., 44% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 262,224 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 51% of its contemporaries.
We're also able to compare this research output to 33 others from the same source and published within six weeks on either side of this one. This one is in the 21st percentile – i.e., 21% of its contemporaries scored the same or lower than it.
