PurposeTo identify the initiation or discontinuation of complementary therapy (CT) and determine the impact of sociodemographic and clinical factors on CT use among cancer patients.Patients and MethodsEligible patients were age 20 or older; newly diagnosed with stomach, liver, or colorectal cancer; and started their initial treatment at the National Cancer Center, Korea, between April 1, 2001, and April 30, 2003. In total, 541 cancer patients were surveyed in face-to-face interviews at baseline, and telephone follow-up interviews were performed every 3 months for 3 years.ResultsA total of 281 patients commenced CT after diagnosis; 164 patients stopped using CT during the follow-up period. The overall cumulative probability of starting CT at 1, 2, and 3 years was 50%, 54%, and 55%, respectively. In a Cox multivariate analysis, stomach and liver cancer were associated with an increased probability of initiating CT compared with colorectal cancer. Patients who were classified as stage I, II, or III at diagnosis were associated with a decreased probability of discontinuing CT compared with stage IV.ConclusionMost cancer patients started to use CT during the initial treatment period. Thus, physicians should communicate with cancer patients about CT at this phase. In particular, more attention should be paid to women and individuals with higher household incomes because these groups are more likely to start CT.

3644 Background: Recent work has shown an association between longer survival and aspirin use in colorectal cancer (CRC) patients with mutated PIK3CA. It has been hypothesized that this survival advantage could occur via blocking the PI3K pathway and allowing apoptosis of mutated cancer cells. The goal of this work is examine the use of aspirin and outcome in CRC patients with PI3KCA mutation. Methods: PIK3CA mutation status was assessed in paraffin-embedded tumor samples from 471 CRC patients between 1998-2010. PIK3CA mutation was assessed by exome sequencing using an Illumina Next Generation (NGS) platform with 50-100X coverage on all patients. The BWA/GATK pipeline was used to identify variants and indels. Because matched normal samples were not available for comparison to identify somatic mutations, filtering of normal variants was performed using 1000 Genomes. The usage of aspirin was collected retrospectively with electronic chart review. Results: Out of 471 patients, 73 were found to have unique PIK3CA mutations by NGS (15.4%). The most common mutations were found at codon 9 (38%) and codon 20 (21%). Patients had a median follow up of 47 months. Initial stage at diagnosis for PIK3CA mutants were as follows: 11 pts were stage I, 31 pts were stage II, 24 pts were stage III and 16 patients were stage IV. Of patients who died, those taking ASA had a 5% cancer related mortality compared to 23% cancer related mortality in non-ASA users. In contrast, the non-cancer related mortality was 25% in ASA users and only 8% in non-ASA users. Cancer specific rates for five year survival were 90% in the ASA group and 57% in the non-ASA group for all stages. In stage IV patients, there was 80% five year survival in the ASA users and 32% in the non-ASA group. Conclusions: There was a trend toward improvement in five year survival for colorectal cancer patients with PIK3CA mutations who used ASA. This trend persisted even in stage IV patients. Notably, non-cancer related deaths were higher in the ASA users, most likely secondary to medical comorbidities that necessitated ASA use. As follow up continues and this data set matures, future work will focus on validating these preliminary results and relating specific PIK3CA mutations to ASA response.

742 Background: The anatomical side of the colon where a tumor arises has been shown to be prognostic in patients treated with first-line therapy; patients with tumors that arise from the left side of the colon have significantly longer survival compared with patients whose tumors arise from the right side of the colon. However, there is little evidence of whether this factor is prognostic in later lines of treatment. The objective of this study was to determine the impact of tumor side on the survival of metastatic colorectal cancer patients who received second line (2L) or third line (3L) therapy. Methods: Metastatic (stage IV) colorectal cancer patients in the Surveillance, Epidemiology, and End Results (SEER) database linked to Medicare claims diagnosed 2001-2005 who received 2L (n = 921) or 3L (n = 502) therapy were included in the study. Overall survival (OS) was determined from the start of the indicated line of therapy and was estimated using the Kaplan-Meier method; statistical differences were tested using the log-rank tests. Results: The distribution of tumor sites was similar for 2L and 3L treated patients (right: 36%; left: 58%; transverse: 6%; for 2L). The median follow up time from start of therapy was 11 months (mo) for 2L and 10 mo for 3L patients. Median OS for left-sided tumors receiving 2L+ therapy was 13.6 mo (95%CI: 11.9, 14.8) compared with 8.7 mo (95%CI: 7.5, 9.9) for right-sided tumors (log-rank p < 0.001). Similar results were seen in patients receiving 3L+ therapy, although the difference was of lesser magnitude. The median OS for patients with left-sided tumors was 10.8 mo (95%CI: 9.6, 12.9) compared with 7.6 mo (95%CI: 5.7, 9.4) for right-sided tumors (log-rank p = 0.002). Conclusions: These results suggest that side of tumor origin remains a prognostic factor for colorectal cancer patients treated in later lines of therapy (2L+).

A drastic difference exists between the 5-year survival rates of colorectal cancer patients with localized cancer and distal organ metastasis. The liver is the most favorable organ for cancer metastases from the colorectum. Beyond the liver-colon anatomic relationship, emerging evidence highlights the impact of liver immune microenvironment on colorectal liver metastasis. Prior to cancer cell dissemination, hepatocytes secrete multiple factors to recruit or activate immune cells and stromal cells in the liver to form a favorable premetastatic niche. The liver-resident cells including Kupffer cells, hepatic stellate cells, and liver-sinusoidal endothelial cells are co-opted by the recruited cells, such as myeloid-derived suppressor cells and tumor-associated macrophages, to establish an immunosuppressive liver microenvironment suitable for tumor cell colonization and outgrowth. Current treatments including radical surgery, systemic therapy, and localized therapy have only achieved good clinical outcomes in a minority of colorectal cancer patients with liver metastasis, which is further hampered by high recurrence rate. Better understanding of the mechanisms governing the metastasis-prone liver immune microenvironment should open new immuno-oncology avenues for liver metastasis intervention.

AbstractColorectal cancer is the second most frequently diagnosed cancer in Spain. Cancer treatment and outcomes can be influenced by tumor characteristics, patient general health status and comorbidities. Numerous studies have analyzed the influence of comorbidity on cancer outcomes, but limited information is available regarding the frequency and distribution of comorbidities in colorectal cancer patients, particularly elderly ones, in the Spanish population. We developed a population-based high-resolution cohort study of all incident colorectal cancer cases diagnosed in Spain in 2011 to describe the frequency and distribution of comorbidities, as well as tumor and healthcare factors. We then characterized risk factors associated with the most prevalent comorbidities, as well as dementia and multimorbidity, and developed an interactive web application to visualize our findings. The most common comorbidities were diabetes (23.6%), chronic obstructive pulmonary disease (17.2%), and congestive heart failure (14.5%). Dementia was the most common comorbidity among patients aged ≥75 years. Patients with dementia had a 30% higher prevalence of being diagnosed at stage IV and the highest prevalence of emergency hospital admission after colorectal cancer diagnosis (33%). Colorectal cancer patients with dementia were nearly three times more likely to not be offered surgical treatment. Age ≥75 years, obesity, male sex, being a current smoker, having surgery more than 60 days after cancer diagnosis, and not being offered surgical treatment were associated with a higher risk of multimorbidity. Patients with multimorbidity aged ≥75 years showed a higher prevalence of hospital emergency admission followed by surgery the same day of the admission (37%). We found a consistent pattern in the distribution and frequency of comorbidities and multimorbidity among colorectal cancer patients. The high frequency of stage IV diagnosis among patients with dementia and the high proportion of older patients not being offered surgical treatment are significant findings that require policy actions.
