    Abstract: Colon cancer (CC) incidence in young adults (age 20-49 years), termed early-onset CC (EO-CC), is increasing. Methods Individual patient data on 35 713 subjects with stage III colon cancer from 25 randomized studies in the Adjuvant Colon Cancer ENdpoint database were pooled. The distributions of demographics, clinicopathological features, biomarker status, and outcome data were summarized by age group. Overall survival, disease-free survival, time to recurrence, and survival after recurrence were assessed by Kaplan-Meier curves and Cox models stratified by treatment arms within studies, adjusting for sex, race, body mass index, performance status, disease stage, grade, risk group, number of lymph nodes examined, disease sidedness, and molecular markers. All statistical tests were 2-sided. Results Using a 5% difference between age groups as the clinically meaningful cutoff, patients with stage III EO-CC had similar sex, race, performance status, risk group, tumor sidedness, and T stage compared with patients with late-onset CC (age 50 years and older). EO-CC patients were less likely to be overweight (30.2% vs 36.2%) and more commonly had 12 or more lymph nodes resected (69.5% vs 58.7%). EO-CC tumors were more frequently mismatch repair deficient (16.4% vs 11.5%) and less likely to have BRAFV600E (5.6% vs 14.0%), suggesting a higher rate of Lynch syndrome in EO-CC. Patients with EO-CC had statistically significantly better overall survival (hazard ratio [HR] = 0.81, 95% confidence interval [CI] = 0.74 to 0.89; P  & lt; .001), disease-free survival (HR = 0.91, 95% CI = 0.84 to 0.98; P = .01), and survival after recurrence (HR = 0.88, 95% CI = 0.80 to 0.97; P = .008) in the analysis without molecular markers; however, age at onset of CC lost its prognostic value when outcome was adjusted for molecular markers. Conclusion Tumor biology was found to be a more important prognostic factor than age of onset among stage III colon cancer patients in the Adjuvant Colon Cancer ENdpoint database.

    Abstract: e22061 Background: BRCA-associated protein-1 (BAP1) is a ubiquitin ligase associated with regulating cell cycle, cell proliferation, DNA damage pathway, and cell death. It also acts as a tumor suppressor gene as seen in hereditary cancer syndrome associated with germline mutations in BAP1. Preclinical studies have shown that PARP-inhibitor treatment of BAP1 mutant cell lines demonstrated significant synthetic lethality, independent of underlying BRCA status suggesting this mutation confers a BRCA-like phenotype. BAP1 is mutated, leading to a loss of functional protein, in up to 30% of several solid tumors including cholangiocarcinoma, mesothelioma, uveal melanoma, and clear cell renal cell carcinoma. Methods: This phase 2, open-label, single arm study aims to exploit the concept of synthetic lethality with the use of the PARP inhibitor niraparib in two biologically distinct cohorts. Eligible patients (pts) with measurable metastatic and incurable solid tumors are assigned to one of the two cohorts: Cohort A (histology-specific): tumors harboring suspected BAP1 mutations including cholangiocarcinoma, uveal melanoma, mesothelioma or clear cell renal cell carcinoma with tissue available for BAP1 mutational assessment via Next Generation Sequencing (NGS); or Cohort B (histology-agnostic): tumors with known DNA damage response (DDR) mutations (Table) confirmed by CLIA-approved NGS. Key inclusion criteria also include age ≥18 years, adequate cardiac, renal, hepatic function and ECOG PS of 0 to 1. Key exclusion criteria include known BRCA1 or BRCA2 mutations or prior PARPi exposure. Pts receive niraparib 200-300mg daily (depending on weight and/or platelet count) continuously. Primary endpoint is objective response rate (ORR), and secondary endpoints are progression free survival (PFS), overall survival (OS), toxicity and exploratory biomarker determinations. Radiographic response by RECIST criteria is measured every 8 weeks while on treatment. Cohort B enrollment is closed. Enrollment in Cohort A continues. A maximum of 47 evaluable subjects is planned with expansion cohorts allowable for histologic or molecular subtypes meeting pre-specified responses. Clinical trial information: NCT03207347.

    Abstract: 439 Background: A prospective observational study of metastatic renal cell carcinoma (mRCC) prior to initiation of systemic therapy has been conducted. (Rini et al., ASCO 2014, abst 4520). A direct cost analysis was undertaken in mRCC patients from this trial matched to historical control mRCC patients treated with immediate systemic therapy. Methods: Histologically-confirmed, asymptomatic mRCC patients without prior systemic treatment were enrolled and followed until starting initial systemic treatment on a prospective trial. Patients underwent clinic visits and radiographic evaluation every 3 months for year 1, every 4 months for year 2, then every 6 months until treatment was initiated per physician discretion. Control mRCC patients who received immediate systemic therapy were matched for age, gender, Heng risk criteria and length of follow up. After clinical review, non mRCC-related encounters were excluded from final analysis. The direct cost of inpatient and outpatient visits plus associated laboratory analysis and imaging studies were compared between the 2 groups using the Wilcoxon signed rank test. Results: Seventeen matched pairs were included in the final analysis. The median (range) number of hospital admissions was 1 (range, 0-6) for the observation group and 1 (range, 0-5) for the immediate therapy group (p=1.0). The median (range) number of outpatient visits in the observation group was 17 (range, 6-39) and 19 (range, 4-59) in the immediate therapy group (p=0.47). In aggregate, the direct costs for the observation group were 30.6% less for outpatient visits and 21.9% less in total (outpatient plus inpatient visits) as compared to the immediate therapy group (p=0.19 for both). Conclusions: Initial observation as a management strategy for a subset of mRCC patients is associated with a non-significant aggregate decrease in direct costs compared to patients requiring immediate treatment. Further study is required to evaluate costs associated with different management strategies over the lifetime of mRCC patients.

    Abstract: TPS476 Background: Neoadjuvant treatment for borderline resectable pancreatic cancer (PCa) is increasing in acceptability, but a standard regimen has yet to be established. Multiple studies have demonstrated feasibility and effectiveness of the FOLFIRINOX (5-fluorouracil, leucovorin, oxaliplatin and irinotecan) regimen in the perioperative setting. However, FOLFIRINOX often requires dose modifications, delays and growth factor support due to excessive toxicity which can complicate care delivery when given neoadjuvantly. Irinotecan liposomal injection (Nal-IRI) is FDA approved with a very tolerable safety profile in refractory metastatic PCa. The current study aims to substitute Nal-IRI for traditional irinotecan in the standard FOLFIRINOX regimen and demonstrate safe and effective delivery in the neoadjuvant setting. Methods: This phase II, open-label, single-arm study targets patients with borderline resectable PCa without metastatic disease. Other key eligibility criteria include age ≥ 18 years, measurable disease by RECIST v1.1, adequate cardiac, renal, hepatic function, and Eastern Cooperative Oncology Group performance status of 0 to 1. Patients receive FOLFNal-IRINOX regimen as per table every two weeks for four months followed by disease reassessment. Patients who remain surgical candidates will undergo surgical resection within four to eight weeks following last dose of therapy. The primary endpoint is to assess safety and feasibility of regimen in perioperative setting. Secondary endpoints include R0 resection rate, clinical, biochemical and radiological response rate and patient-reported quality of life as measured by the NCI validated FACT-G scale. Enrollment continues to a maximum of 28 evaluable patients to demonstrate a reduction in historical 30 day postoperative complication rate. FOLFNal-IRINOX regimen.

    Abstract: 691 Background: The incidence of colorectal cancer (CRC) in young patients ( 〈 50 years) is increasing but little is known about disease characteristics and treatment outcomes in this patient population. Methods: CRC patients diagnosed at 〈 50 years of age (UF institutional registry 2000-2017) constituted the IRB approved study cohort. Statistical methods included descriptive statistics, uni-variable cox proportional hazard regression model, Pearson chi-square exact and Wilcoxon rank-sum test. Results: The median age at diagnosis was 45 years (range 17-50, n = 286) with 212 (74%) diagnosed between age 40-50. One third (35.7%) of patients had rectal primary and most common histology was adenocarcinoma (ACa, 84.6%) and 20% of those had poorly differentiated tumor. More than half of patients had an advanced primary (T3/T4, 65%) and 44% had lymph node positive disease. A trend towards increased delivery of perioperative therapy was seen in early staged disease. (See table) Patients who underwent curative resections had better hemoglobin (p = 0.005) and albumin levels (Alb, p 〈 0.001) and lower CEA level (p 〈 0.001). Factors associated poor survival were low alb levels ≤ 34 g/l, advanced primary tumor (T3/T4), nodal disease (N1/N2) and presence of diffuse metastasis. For stage 4 disease, the cancer-specific survival (CSS) at 1 year was 77.2%, 3-year CSS was 46.1% and 5-year CSS was 29%; survival was better (HR = 0.4; 95% CI 0.2-0.6, p 〈 0.001) among patients who underwent metastatectomy. Conclusions: Our data suggests that younger CRC patients were more likely to be managed in an aggressive manner with a higher proportion of early stage patients receiving perioperative therapy. A suggestion of an improved CSS was seen in advanced stage disease even with similar prognostic factors. Review of larger datasets are warranted. [Table: see text]

    Abstract: 796 Background: In colorectal cancer (CRC), clinical guidelines and immunotherapy treatment selection requires knowledge of tumor DNA mismatch repair gene deficiencies (dMMR) or accumulation of microsatellite repeats through genomic errors (MSI-H). Tumors harboring dMMR/MSI-H are found in 15- 20% of early stage CRC while the prevalence is ~5% in metastatic disease. Reflex testing of CRC to identify these important subsets has been proposed as a system-solution to improve identification. We present a large, single-institutional database of CRC reflexively profiled for MSI/MMR status at the University of Florida (UF). Methods: Beginning in 2009, stage IV CRC underwent reflex testing for MSI/MMR status. Earlier stage CRC testing began in subsequent years. For all new CRC diagnosed at UF, concurrent testing for dMMR by IHC (MLH1, PMS2, MSH2, MSH6), MSI by PCR (Promega MSI kit) and NGS is performed with appropriate positive and negative controls. IHC protein loss is confirmed by second GI pathologist. MSI is not performed if inadequate adjacent normal tissue. We conducted a retrospective analysis of all CRC samples analyzed between 2009 and 2017. Clinical data was collected from the EMR. This study was approved by the UF IRB. Results: A total of 388 new CRC cases were reflex tested (16% Stage I, 23% Stage II, 35% Stage III, and 25% Stage IV). Median age at diagnosis was 63 yrs (range: 17-98 yrs), 51% male and 79% white. Both MMR and MSI were performed in 244 (63%) tumors with 100% concordance when concurrently tested. dMMR/MSI-H incidence (20% in overall population) decreased with stage: I/II (31%), III (18%) and IV (~9%) and was associated with BRAF V600E mut in 36/76 cases (47%). Importantly, in pts 〈 50 yrs, 13% of stage IV patients were dMMR/MSI-H. Conclusions: Reflex testing of MMR/MSI status in CRC is feasible with concordant results. Routine testing results in identification of dMMR/MSI-H at or higher than published rates. Notable findings include the high prevalence in those with sporadic CRC and/or younger than 50 yrs. Continued impact analysis of this approach is warranted to maximize IO therapy offering.
