Abstract The treatments provided to and survival of patients with recurrent vs de novo stage IV advanced breast, lung, and colorectal cancer may differ but have not been well studied. Using population-based data from the Cancer Research Network for 4510 patients with advanced breast, lung, or colorectal cancer, we matched recurrent/de novo patients on demographic factors. We found longer survival for recurrent vs de novo lung cancer (182 matched pairs); no significant difference for colorectal cancer (332 matched pairs); and shorter survival for recurrent vs de novo breast cancer (219 matched pairs). Compared with recurrent cases, chemotherapy use and radiation therapy use were more common among de novo cases. Differences in treatment and survival between recurrent and de novo advanced cancer patients could inform prognostic estimates and clinical trial design.

Data are limited on oncogene mutation frequencies in polyps from principally asymptomatic participants of population-based colorectal cancer screening studies. In this study, DNA from 204 polyps, 5 mm or larger, were collected from 176 participants of the NORCCAP screening study and analyzed for mutations in KRAS, BRAF, and PIK3CA including the rarely studied KRAS exons 3 and 4 mutations. KRAS mutations were identified in 23.0% of the lesions and were significantly associated with tubulovillous adenomas and large size. A significantly higher frequency of KRAS mutations in females was associated with mutations in codon 12. The KRAS exon 3 and 4 mutations constituted 23.4% of the KRAS positive lesions, which is a larger proportion compared to previous observations in colorectal cancer. BRAF mutations were identified in 11.3% and were associated with serrated polyps. None of the individuals were diagnosed with de novo or recurrent colorectal cancer during the follow-up time (median 11.2 years). Revealing differences in mutation-spectra according to gender and stages in tumorigenesis might be important for optimal use of oncogenes as therapeutic targets and biomarkers.

13568 Background: Oxaliplatin and 5FU based regimens have become standard first line treatment for stage IV colorectal cancer. At our institution predominately the regimens FOLFOX6 (oxaliplatin/infusional 5FU via a central venous catheter) and XELOX (oxaliplatin/ capecitabine given orally) are used. We performed a retrospective review of 40 patients to see if any differences, primarily in toxicities, but also in response, emerged. Methods: . Twenty consecutive patients with Stage IV colorectal cancer who received FOLFOX6 as initial therapy and twenty consecutive patients who received initial XELOX, with the oxaliplatin given via a peripheral IV, were analyzed. The decision to administer FOLFOX6 or XELOX was not made for clinical reasons, but came about from logistical difficulties placing central venous catheters in our institution, due to cost and operating time. Comparisons were performed with a Mann Whitney test. The two groups were well matched in terms of sex, age, and performance status. Response evaluations were made based on RECIST criteria. Results: Toxicities compared in the two groups (FOLFOX6 v. XELOX) were gastrointestinal, >Gr. II (5 v. 20%); dermatologic, >Gr. III (0 v. 35%); bone marrow, > Gr. II (15 v. 20%); neurologic, >Gr. III peripheral neuropathy (10 v. 10%); and development of arm pain/discomfort (0 v. 30%). The two toxicities reaching a significant difference, with the higher incidence from XELOX, were > Grade II dermatitis (p= 0.03) and development of arm pain (p=0.05). The response rate of FOLFOX6 was 75% and that for XELOX was 55% (p value of 0.144). Conclusions: Our conclusions from this analysis are that the two regimens are comparable in terms of response, but that FOLFOX6 may be preferable in order to avoid severe dermatitis and if XELOX is the treatment choice, serious consideration should given to administer the oxaliplatin via a central catheter. No significant financial relationships to disclose.

e14186 Background: Overall survival in colorectal cancer is influenced by obesity, age, gender and stage at diagnosis. However, in minority based populations, effect of the above factors on overall survival has not been studied in any detail. Hence, we undertook this retrospective study to evaluate effect of above factors on overall survival in young colorectal cancer patients. Methods: 1,195 subjects with colorectal cancer treated at John H. Stroger Hospital of Cook County between 2000 and 2008 were retrospectively analyzed. 179 subjects with age 50 years and younger were identified. 146 of 179 subjects with available Body Mass Index (BMI) in kg/m2 were included in the study. Effect of BMI, age, sex, race, LDH and CEA levels, stage, site of tumor, smoking and family history on overall survival was evaluated using standard statistical multivariate analysis. Results: In our population, 22 of 146(15%) were underweight (BMI<20), 56 of 146(38.4%) were normal weight (BMI 20-24.9), 46 of 146(31.5%) were overweight (BMI 25-29.9) and 22 of 146(15%) were obese (BMI >30). Male: female ratio was 1.4:1. 75 of 146(51.7%) were African American, 23 of 146(15.9%) were Caucasians. 50 of 146(34.2%) were stage IV colorectal cancer at diagnosis. On univariate analysis, BMI<20(p=0.031, HR 2.1, 95% CI 1.15-3.82), CEA >4ng/ml (p=0.005, HR 1.93, 95% CI 1.21-3.08) and stage IV colorectal cancer (p<0.001, HR 6.1, 95% CI 2.42-15.53) were significantly associated with decreased overall survival. LDH<200 U/L was significantly associated with improved overall survival (p 0.029, HR 0.6, 95% CI 0.391-0.950). On multivariate analysis, stage IV colorectal cancer was a single significant independent predictor of overall survival (p=0.001, 95% CI 2.47-27.78). CEA>4ng/ml was marginally significant for decreased overall survival (p=0.06, 95% CI 0.978-3.015). On the contrary, no statistically significant difference was found on overall survival with age, BMI>20, gender, race, tumor location, smoking and family history. Conclusions: Advanced stage and CEA >4ng/ml are independent prognostic variables for decreased overall survival in minority based population of young colorectal cancer.

210 Background: Effectively managing comorbidities is an essential component of high-quality cancer care. Evidence suggests colorectal cancer (CRC) patients with multiple comorbid conditions are less likely to complete standard treatments and can have lower rates of survival. In order to provide personalized care, it is critical to understand how comorbid conditions cluster within CRC patients. Methods: We identified Kaiser Permanente Southern California CRC patients diagnosed with first malignancy between 01/01/2008 - 12/31/2013. We used latent class analysis to identify clinically useful phenotypes defined by combinations of comorbidities at diagnosis, and compared survival using the Kaplan-Meier method. Results: The cohort included 7803 patients: 52% male; average age at diagnosis 66 years (SD: 13); 22% Hispanic, 15% Black, 9% Asian, 52% White; 42% Stage I, 22% Stage II, 22% Stage III, and 14% Stage IV. One-fifth of patients had a Charlson comorbidity index score of ≥ 4. We found 4 distinct classes (Lo-Mendell-Rubin p<0.001). Class 1 was relatively healthy with few comorbidities (Table). Class 2 included individuals with cardiovascular diseases; those in Class 3 had complicated diabetes. Class 4 members had multiple chronic conditions, including diabetes with micro- and macrovascular complications. Kaplan-Meier estimates revealed a statistically significant difference in overall survival by class (log rank p<0.001). Conclusions: We identified 4 clinically distinct classes of comorbid conditions in CRC patients. These data can be used to inform personalized care for CRC patients throughout the cancer care continuum. [Table: see text]

Abstract Background and study aims National societies recommend colorectal cancer (CRC) screening 10 years after a normal (“negative”) colonoscopy in low-risk individuals. We studied the impact of a 10-year repeat colonoscopy on the risk of early incident CRC. Patients and methods We used health administrative data from Ontario, Canada, to conduct a population-based retrospective cohort study in 50 – 74-year-old individuals at low-to-moderate risk of CRC who had a negative colonoscopy between 1996 and 2001. We approximated exposure to repeat colonoscopy using an 8 – 12-year window. We excluded individuals who underwent lower endoscopy or colectomy, developed CRC, or were lost to follow-up between the baseline and repeat colonoscopies. We matched exposed individuals 1:1 to individuals who did not undergo lower endoscopy within 12 years for age, sex, and calendar year of baseline colonoscopy, and followed matched pairs for incident CRC. The primary analysis was multivariable hazards regression, adjusting for competing risks. Results A total of 13 350 matched pairs were observed for a median of 4.5 years (interquartile range 3.2 – 5.9 years). The cumulative probability of CRC following the matching date was 0.70 % (95 % confidence interval [CI] 0.42 % – 1.11 %) in individuals who underwent repeat colonoscopy and 0.77 % (95 %CI 0.48 % – 1.2 %) in individuals who did not undergo repeat colonoscopy. The adjusted hazard ratio for CRC was 0.91 (95 %CI 0.68 – 1.22). Conclusions We did not find an association between a second colonoscopy performed 10 years after a negative colonoscopy and early incident CRC. Our findings support the need for further studies on the utility of 10-year re-screening with colonoscopy in this setting.

Purpose. The purpose of the current meta-analysis was to evaluate whether multidisciplinary team improved overall survival of colorectal cancer. Methods. PubMed, EMBASE, and Cochrane Library database were searched from inception to October 25, 2020. The hazard ratio (HR) and 95% confidence (CI) of overall survival (OS) were calculated. Results. A total of 11 studies with 30814 patients were included in this meta-analysis. After pooling the HRs, the MDT group was associated with better OS compared with the non-MDT group ( HR = 0.81 , 95% CI 0.69-0.94, p = 0.005 ). In subgroup analysis of stage IV colorectal cancer, the MDT group was associated with better OS as well ( HR = 0.73 , 95% CI 0.59-0.90, p = 0.004 ). However, in terms of postoperative mortality, no significant difference was found between MDT and non-MDT groups ( OR = 0.84 , 95% CI 0.44-1.61, p = 0.60 ). Conclusion. MDT could improve OS of colorectal cancer patients.

BackgroundPIK3CA is a high-frequency mutation gene in colorectal cancer, while its prognostic value remains unclear. This study evaluated the mutation tendency, spectrum, prognosis power and predictive power in cetuximab treatment of PIK3CA in Chinese CRC cohort.MethodsThe PIK3CA exon 9 and 20 status of 5763 CRC patients was detected with Sanger sequencing and a high-resolution melting test. Clinicopathological characteristics of 5733 patients were analyzed. Kaplan-Meier method and nomogram were used to evaluate the overall survival curve and disease recurrence, respectively.ResultsFifty-eight types of mutations in 13.4% (771/5733) of the patients were detected. From 2014 to 2018, the mutation rate of PIK3CA increased from 11.0% to 13.5%. At stage IV, exon 20 mutated patients suffered shorter overall survival time than wild-type patients (multivariate COX regression analysis, HR = 2.72, 95% CIs = 1.47-5.09; p-value = 0.012). At stage III, PIK3CA mutated patients were more likely to relapse (multivariate Logistic regression analysis, exon 9: OR = 2.54, 95% CI = 1.34-4.73, p = 0.003; exon 20: OR = 3.89, 95% CI = 1.66-9.10, p = 0.002). The concordance index of the nomogram for predicting the recurrence risk of stage III patients was 0.685. After cetuximab treatment, the median PFS of PIK3CA exon 9 wild-type patients (n = 9) and mutant patients (n = 5) did not reach a significant difference (3.6 months vs. 2.3 months, Log-rank test, p-value = 0.513).ConclusionsWe found that PIK3CA mutation was an adverse predictive marker for the overall survival of stage IV patients and recurrence of stage III patients, respectively. Further more, we suggested that PIK3CA exon 9 mutations are not negative predictors of cetuximab treatment in KRAS, NRAS, and BRAF wild-type mCRC patients.
