e19005 Background: CALGB 10403 is a pediatric-inspired ALL regimen that has recently been shown to have improved survival rates in adolescents and young adults with ALL when compared to historical outcomes with traditional adult ALL regimens (Stock et. al, 2019). Methods: This is a retrospective cohort study of ALL patients who received induction CALGB 10403 at Stanford University (both on and off trial), achieved CR1, and subsequently relapsed. Primary outcome of interest was event free survival from time of diagnosis. Events were defined as relapse or death. Secondary outcomes were overall survival and event free survival from first relapse. Patients were censored at time of last clinical follow up. Results: 25 patients met inclusion criteria and received front-line CALGB 10403 from April 2010 to September 2018. At the time of initial diagnosis median age was 30 years (range 18 – 39 years). 68% of patients were male. 48% of patients were overweight and 40% were obese. 76% of patients had precursor B cell ALL while 24% had T cell ALL. 12% had CNS disease at diagnosis. 36% of patients had WBC greater than 30k. 12% of patients had CRLF2 rearrangement. 12% of patients were MRD positive after first induction. 20% of patients received rituximab. Median event free survival time from diagnosis was 20 months (range 3 – 79 months) and median overall survival time was 53 months. Blinatumomab was the most common salvage therapy after 1st relapse, followed by inotuzumab. 15 patients (60%) achieved CR2, of which 4 (27%) were MRD positive after 2nd induction. 15 patients (60%) went to HSCT. Of the patients who achieved CR2, 8 relapsed for a second time. Median event free survival time after first relapse was 23 months. Survival 1 year after relapse was 60%. 11 of the 25 patients were alive at last follow up. Median follow up time of survivors was 6 years. Conclusions: This is a descriptive retrospective cohort study of adult patients in a real world setting who received CALGB 10403 induction and subsequently relapsed. Compared to other studies of relapsed ALL patients who were induced with traditional chemotherapy (Fielding et. al, 2007), survival 1 year after relapse was much higher (60% vs. 22%). As CALGB 10403 becomes an increasingly common induction regimen for AYA and adults with ALL, further outcomes study is required.[Table: see text]

Larynx Cancer

e18044 Background: Organ preservation approaches to treatment of locally advanced larynx cancers are widely used and consist of radiotherapy (RT) with or without concurrent systemic therapy (CRT). Analyses of the National Cancer Database point to decreasing survival as CRT became widely adopted in place of total laryngectomy (TL). Tumor volume in T3 laryngeal tumors has been postulated as one variable to explain this finding, with higher volume associated with lower local control based on small sample size studies largely in pre-intensity modulated radiotherapy (IMRT) era, and low volume T3 tumors being associated with improved local control with CRT. We sought to validate these findings in a contemporary cohort of T3 larynx patients treated with IMRT. Methods: This was a national, multicentre retrospective cohort study of patients diagnosed with American Joint Committee on Cancer (AJCC) T3 N0-3 M0 glottic and supraglottic cancers who underwent curative intent IMRT with or without systemic treatment from 2002-2018. Tumor volumes were calculated using a validated standardized approach by a Neuroradiologist. Primary predictor was tumor volume, primary outcome was local control (LC), and secondary outcomes included overall survival (OS), as well as late grade 3+ toxicities. Kaplan Meier estimates and log-rank tests were used for survival analyses, with Cox proportional hazards used for univariable analyses. Results: 246 patients met inclusion criteria, 147 glottic and 99 supraglottic cancers. At baseline, glottic patients were more likely to be male (p < 0.01), have a fixed vocal cord (p < 0.01), not have pre-epiglottic space invasion ( < 0.01), be cN0 (p < 0.01), and have lower grade tumors (p < 0.01). Mean tumor volumes for glottic and supraglottic tumors were 5.0 (4.2-5.8) cc and 13.0 (10.3–15.6) cc respectively. Univariable analysis showed systemic therapy was associated with improved local failure (HR 0.49, 95%CI 0.24 – 0.99, p = 0.05). Within the glottic cohort, tumor volume was not associated with local failure (HR 1.09, 95%CI 0.71 – 1.67, p = 0.38), however having a local failure event was associated with increased feeding tube dependence (HR 2.52, 95%CI 1.05 – 6.02, p = 0.04). Median local failure free survival in the overall cohort was 28.5 months, with median OS 23.2 months. There was a trend towards improved local control in the supraglottic cohort compared to glottic patients (log-rank p = 0.08), but the supraglottic cohort had significantly worse overall survival (log-rank p = 0.02). Conclusions: In this retrospective cohort study, there were baseline and outcome differences between patients with T3 glottic and supraglottic larynx cancer, with worse overall survival in supraglottic patients. Tumor volume was not associated with local control in the glottic cohort. These findings are pending further validation in a larger cohort and will be analyzed separately for supraglottic tumors.
