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]

Study designRetrospective cohort study.IntroductionDebates remain regarding the role of lymphadenectomy in patients with apparent stage IA endometrial cancer, especially subtypes with a favorable prognosis. This study aimed to explore the prognostic value of staging surgeries in apparent stage IA endometrial endometrioid cancer patients in a retrospective cohort study.MethodsCases from June 1, 2010 to June 1, 2017 were reviewed in patients with pathologically confirmed endometrial endometrioid carcinoma limited to <1/2 of the myometrium, without extrauterine metastasis on preoperative evaluation and during surgical inspection. Survival outcomes were compared between patients with and without lymphadenectomy and between patients with and without metastasis to lymph nodes.ResultsIn total, 1,312 eligible patients were included, among which 836 underwent staging surgeries and 476 underwent simple hysterectomy. Twenty-eight patients were found with metastasis to retroperitoneal lymph nodes. After a median follow-up of 57.4 months, lost to follow-up, recurrence, death, and cancer-specific death occurred in 28, 39, 24, and 16 patients, respectively. In a univariate analysis, lymphadenectomy of the pelvis with or without para-aortic lymph nodes had no significant impact on disease-free survival, overall survival or cancer-specific overall survival (p values >0.05). However, after adjusting for important baseline risk factors [menopausal status, tumor differentiation, maximum diameter and location, lymph-vascular space invasion (LVSI) status, and postoperative adjuvant therapy), lymphadenectomy resulted in significantly improved survival outcomes (p values <0.05). Menopause (odds ratio [OR] 4.7, 95% confidence interval [CI] 1.3–16.4, p=0.015), tumor diameter larger than 2 cm (OR 4.6, 95% CI 1.3–16.0, p=0.016), grade 3 tumors (OR 3.0, 95% CI 1.0–8.5, p=0.042), positive LVSI (OR 8.7, 95% CI 3.7–20.4, p<0.001) and lower uterine segment involvement (OR 3.1, 95% CI 1.4–7.2, p=0.007) had more extrauterine metastases.ConclusionIn cases of apparent stage IA endometrioid endometrial carcinoma, staging surgeries should be considered in patients with larger, higher grade tumors, positive LVSI, or lower uterine segment involvement.

606 Background: While optimal management of anal cancer has become better defined in light of recent clinical trials including selected patients, the outcomes in an unselected population are less well defined. We reviewed the outcomes of anal cancer patients in a population referred to a sole-provider regional cancer program at the Ottawa Hospital over a 12 year period (2000 to 2011). Methods: Patient data was collected from hospital records, including demographic, treatment and outcome. Outcomes of interest included overall and recurrence free survival, as well as colostomy free survival. Results: Patients were 72% (n = 130) female and 28% (n = 50) male, 6.6% (n = 12 males) HIV positive, 60% (n = 108) ever smokers, mean age 62 [range 35-90] years. Most frequent presenting symptoms were blood per rectum (87%) and anal pain (80%). Treatment intent was curative in 87%. Treatment included radiotherapy (94%), brachytherapy (26%), chemotherapy (73%). Combined chemoradiotherapy was received by 71%, including MMC-5FU (n = 87) and cisplatin+5FU (n = 41). Among patients treated with curative-intent, 72% had a complete response, 31% local/regional recurrence, 16% required salvage surgery and 21% had distant recurrence. Colostomy rate was 23%. 5 year overall survival (OS) was not significantly different for patients by HIV status; 52 vs. 60% for HIV positive vs negative, respectively, HR 1.36, p = 0.47. Survival was superior if MMC+5FU was used first vs. Cisplatin+5FU; 5yOS 73 vs 46% respectively, [HR 0.45 (95%CI 0.25 – 0.83), log rank p = 0.013]. Conclusions: The outcomes of patients in this large retrospective cohort study are similar to the outcomes of patients in highly selective clinical trials. Five year overall survival and colostomy free survival are encouraging. MMC +5FU was found to be superior to Cisplatin +5FU. Further study is required to improve outcomes for patients with metastatic disease.

Aortic Repair

Aortoesophageal fistula (AEF) caused by esophageal cancer (EC) is a rare but life-threatening complication. However, the optimal management strategy remains undetermined. Previous cases have demonstrated that thoracic endovascular aortic repair (TEVAR) is effective for prophylactic management. In our study, we evaluated the management of AEF with elective TEVAR over salvage TEVAR. In our single-center retrospective cohort study, forty-seven patients with cT4M0 EC were included in this study, and we divided them into salvage (Group S) and elective (Group E) groups based on whether TEVAR was performed before the hemorrhagic AEF occurred. Our study outcomes included survival and complication rate after TEVAR. Group E showed better overall 90-day survival and aortic-event-free survival in 90-day and 180-day over Group S. More patients in Group E could receive subsequent chemoradiotherapy or esophagectomy. Significantly fewer AEF-related complications, including recurrent hemorrhagic events after TEVAR, hypoperfusion-related organ injury, and bloodstream infection, were noted in Group E. In patients with advanced EC-invading aorta, elective TEVAR offered an early overall and aortic-event-free survival benefit compared to salvage TEVAR. By reducing the AEF-related complications, elective TEVAR could provide more patients receiving subsequent curative-intent treatment.

This is a retrospective cohort study using notification data in South Korea. We evaluated the nationwide status, regional differences, and the determinants of treatment outcomes among tuberculosis patients. Treatment success rate improved from 77.0% in 2012 to 86.0% in 2015. The lost to follow-up rate was higher among older people, males, and foreign nationals. Health care facilities designated for the Public-Private Mix (PPM) project showed higher success rate and lower rate of lost to follow-up. Moreover, municipalities with low regional deprivation index had higher PPM project coverage. Since there is a large regional difference in the coverage of the PPM project, an additional community-based support program should be implemented, especially for tuberculosis patients residing in region with low PPM project coverage.

ObjectivesMany researchers have expected pioglitazone to serve as an effective neuroprotective agent against Parkinson’s disease (PD). Therefore, we conducted this cohort study to investigate the association between pioglitazone use and PD by using a large Asian population-based dataset in Taiwan.DesignRetrospective cohort study.SettingTaiwan.Participants7906 patients with diabetes who had received pioglitazone were defined as the study cohort, and 7906 matched patients with diabetes who had not received pioglitazone were defined as the comparison cohort.Primary and secondary outcome measuresWe tracked each patient individually over a 5-year follow-up period to identify those diagnosed as having PD during this period. We performed Cox proportional hazard regression analyses to evaluate the HRs for PD between the study and comparison cohorts.ResultsThe findings indicated that among the sampled patients, PD occurred in 257 (1.63%): 119 (1.51%) pioglitazone users and 138 (1.75%) non-users. The adjusted HR for PD within the follow-up period was 0.90 (95% CI: 0.68 to 1.18) in the patients who had received pioglitazone compared with the matched patients who had not received pioglitazone. Moreover, this study revealed that pioglitazone use was not associated with PD incidence in men (HR: 1.06, 95% CI: 0.71 to 1.59) or women (HR: 0.84, 95% CI: 0.61 to 1.15).ConclusionsThis study did not find the relationship between pioglitazone use and PD incidence, regardless of sex, among an Asian population of patients with diabetes.
