Multi-institutional Evaluation of Curative Intent Chemoradiotherapy for Patients With Clinical T1N0 Esophageal Adenocarcinoma.

ABSTRACT: Purpose:To evaluate the safety and efficacy of definitive chemoradiotherapy (CRT) for patients with clinical T1N0M0 esophageal adenocarcinoma. Methods and Materials:This was a retrospective study of patients with clinical T1N0 adenocarcinoma of the esophagus treated with curative-intent CRT between 2004 and 2017 at 2 tertiary care centers. Patients received CRT instead of esophagectomy owing to medical comorbidities or patient preference. Toxicities were evaluated according to Common Terminology Criteria for Adverse Events version 4.03. The Kaplan-Meier method was used to estimate overall, progression-free, and disease-specific survivals. Results:Twenty-eight patients were included for analysis. Median age was 76 years (range 55-90). The majority of patients were male (93%) and had a history of Barrett's esophagus (71%). Tumor characteristics included distal esophagus location (93%), clinical stage T1b (86%), and median length of 2 cm (range, 1-9). Prior endoscopic resection was performed in 57%.The median follow-up was 44 months (range, 4-146). The acute grade 3 adverse events were observed in 7 patients (25%). One patient died of complications potentially related to chemoradiation. Eight patients (29%) had disease progression at a median of 7.6 months after CRT. First site of progression was local only (14%), local and regional (11%), or distant (4%). Salvage locally directed treatment was performed in 3 of 4 patients with local-only recurrence. The 3-year overall survival, progression-free, and disease-specific rates were 78%, 62%, and 81%, respectively. Conclusion:CRT is a safe and effective curative treatment strategy for select patients with clinical T1N0M0 esophageal adenocarcinoma.

Project description:ImportanceComposite measures may be superior to individual measures for the analysis of hospital performance and quality of surgical care.ObjectiveTo determine the incidence of a so-called textbook outcome, a composite measure of the quality of surgical care, among patients undergoing curative-intent resection of intrahepatic cholangiocarcinoma.Design, setting, and participantsThis cohort study involved an analysis of a multinational, multi-institutional cohort of patient from 15 major hepatobiliary centers in North America, Europe, Australia, and Asia who underwent curative-intent resection of intrahepatic cholangiocarcinoma between 1993 and 2015. Data analysis was conducted from April 2018 to May 2018.Main outcomes and measuresHospital variation in the composite end point of textbook outcome, defined as negative margins, no perioperative transfusion, no postoperative surgical complications, no prolonged length of stay, no 30-day readmissions, and no 30-day mortality. Secondary end points were factors associated with achieving textbook outcomes.ResultsAmong 687 patients (of whom 370 [53.9%] were men; median patient age, 61 [range, 18-86] years) undergoing curative-intent resection of intrahepatic cholangiocarcinoma, a textbook outcome was achieved in 175 patients (25.5%). Being 60 years or younger (odds ratio [OR], 1.61 [95% CI, 1.04-2.49]; P = .03), absence of preoperative jaundice (OR, 4.40 [95% CI, 1.28-15.15]; P = .02), no neoadjuvant chemotherapy (OR, 2.57 [95% CI, 1.05-6.29]; P = .04), T1a/T1b-stage disease (OR, 1.58 [95% CI, 1.01-2.49]; P = .049), N0 status (OR, 3.89 [95% CI, 1.77-8.54]; P = .001), and no bile duct resection (OR, 2.46 [95% CI, 1.25-4.84]; P = .009) were independently associated with achieving a textbook outcome after resection. A prolonged length of stay had the greatest negative association with a textbook outcome. A nomogram to assess the probability of textbook outcome was developed and had good accuracy in both the training data set (area under the curve, 0.755) and validation data set (area under the curve, 0.763).Conclusions and relevanceIn this study, while hepatic resection for intrahepatic cholangiocarcinoma was performed with less than 5% mortality in specialized centers, a textbook outcome was achieved in only approximately 26% of patients. A textbook outcome may be useful for the reporting of patient-level hospital performance and hospital variation, leading to quality improvement efforts after resection of intrahepatic cholangiocarcinoma.

Project description:ObjectivesTo assess the effectiveness of fluorine-18 fluorodeoxyglucose (FDG) positron-emission tomography-computed tomography (PET-CT) and magnetic resonance imaging (MRI) for response assessment post curative-intent chemoradiotherapy (CRT) in anal squamous cell carcinoma (ASCC).MethodsConsecutive ASCC patients treated with curative-intent CRT at a single centre between January 2018 and April 2020 were retrospectively identified. Clinical meta-data including progression-free survival (PFS) and overall survival (OS) outcomes were collated. Three radiologists evaluated PET-CT and MRI using qualitative response assessment criteria and agreed in consensus. Two-proportion z test was used to compare diagnostic performance metrics (sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), accuracy). Kaplan-Meier analysis (Mantel-Cox log-rank) was performed.ResultsMRI (accuracy 76%, PPV 44.8%, NPV 95.7%) and PET-CT (accuracy 69.3%, PPV 36.7%, NPV 91.1%) performance metrics were similar; when combined, there were statistically significant improvements (accuracy 94.7%, PPV 78.9%, NPV 100%). Kaplan-Meier analysis demonstrated significant differences in PFS between responders and non-responders at PET-CT (p = 0.007), MRI (p = 0.005), and consensus evaluation (p < 0.001). Cox regression analysis of PFS demonstrated a lower hazard ratio (HR) and narrower 95% confidence intervals for consensus findings (HR = 0.093, p < 0.001). Seventy-five patients, of which 52 (69.3%) were females, with median follow-up of 17.8 months (range 5-32.6) were included. Fifteen of the 75 (20%) had persistent anorectal and/or nodal disease after CRT. Three patients died, median time to death 6.2 months (range 5-18.3).ConclusionCombined PET-CT and MRI response assessment post-CRT better predicts subsequent outcome than either modality alone. This could have valuable clinical benefits by guiding personalised risk-adapted patient follow-up.Key points• MRI and PET-CT performance metrics for assessing response following chemoradiotherapy (CRT) in patients with anal squamous cell carcinoma (ASCC) were similar. • Combined MRI and PET-CT treatment response assessment 3 months after CRT in patients with ASCC was demonstrated to be superior to either modality alone. • A combined MRI and PET-CT assessment 3 months after CRT in patients with ASCC has the potential to improve accuracy and guide optimal patient management with a greater ability to predict outcome than either modality alone.

Project description:Importance:Despite standard chemoradiotherapy (CRT), most women with lymph node (LN)-positive cervical cancer experience disease recurrence. Immunotherapy is being investigated in the up-front treatment setting. Objectives:To assess the safety of sequential immunotherapy after CRT and to investigate human papillomavirus (HPV) genotype and HLA allele status on survival and programmed cell death 1 (PD-1) expression before and after CRT and sequential immunotherapy. Design, Setting, and Participants:This prospective phase 1 trial conducted in 29 Gynecology Oncology Cooperative Group member institutions enrolled participants from December 18, 2012, to August 31, 2016, with a 14.8-month median follow-up and translational end points. Thirty-four women with International Federation of Gynecology and Obstetrics stage IB2 to IVA cervical cancer with positive pelvic LNs, para-aortic LNs, or both were enrolled; 13 did not receive ipilimumab and were excluded from the analysis. Data were analyzed from January 21 to April 4, 2018. Interventions:Treatment consisted of 6 weekly doses of cisplatin, 40 mg/m2, concurrent with radiotherapy. After completion of chemotherapy, sequential ipilimumab was given every 21 days for 4 doses. Two dosage levels of ipilimumab, 3 mg/kg and 10 mg/kg, were studied to identify the maximum tolerated dose. Main Outcomes and Measures:The primary end point was safety, and the secondary end points were overall survival and progression-free survival. Exploratory end points included HPV genotype, HLA allele status, and PD-1 expression measured in peripheral blood. Results:The median age of the 32 participants included in the intent-to-treat analysis was 50 (range, 26-61) years, and 22 patients (69%) were white. Of the 21 patients who received ipilimumab, all had positive pelvic LN, and 6 (29%) had positive para-aortic LNs. All patients completed CRT, and of the 21 patients who received at least 2 cycles of ipilimumab, 18 (86%) completed 4 cycles of ipilimumab, and 3 (14%) completed 2 cycles. The maximum tolerated dose was 10 mg/kg. Two of the 21 patients (9.5%) who received ipilimumab had self-limiting grade 3 toxic effects (lipase increase; dermatitis). The 12-month overall survival was 90%, and progression-free survival was 81%. Human papillomavirus genotype and HLA subtype were not associated with progression-free survival or overall survival. T cells expressing PD-1 increased after CRT, and levels were sustained with ipilimumab. Conclusions and Relevance:This study's findings suggest that the use of immunotherapy after CRT for curative-intent treatment of patients with cervical cancer is tolerable and effective. The results indicated that PD-1 was upregulated after CRT and sustained with sequential ipilimumab therapy. These immune findings may help guide future therapies to harness the activated T-cell phenotype in patients with node-positive cervical cancer.

Project description:ObjectivesThe aim of this study was to characterize the cardiovascular disease (CVD) profile and describe the incidence and characteristics of cardiovascular (CV) events in patients with esophageal cancer (EC) following chemoradiation and surgery.BackgroundUnderlying CVD is a concern in patients with EC receiving curative treatment with chemoradiation and surgery.MethodsConsecutive patients with EC referred for curative treatment were enrolled. Clinical CVD status, ongoing CVD treatment, cardiac function, and physical performance were assessed before chemoradiation. During a 90-day follow-up period, all CV events were noted and classified after in-depth medical record review. CV events were defined by major adverse CV events (transient ischemic attack, imaging-verified new stroke, unstable angina, heart failure or cardiomyopathy) or by Common Terminology Criteria for Adverse Events grade ≥3 (arrhythmia, thromboembolic events, or pericardial effusion requiring pericardiocentesis).ResultsAmong 55 patients enrolled (median age 67 years; range: 50-86 years; 89% men), 22% had CVD prior to chemoradiation, and 11% with pre-existing CVD were inadequately treated according to current CV guidelines. Thirteen patients (24%) developed 15 events during follow-up. Pre-existing atrial fibrillation and a dilated left atrium were significantly associated with subsequent CV events. Left ventricular (LV) systolic dysfunction was frequently noted; 51% had impaired LV global longitudinal strain (<18%), and 16% had LV ejection fraction <50%.ConclusionsA systematic cardiac evaluation prior to chemoradiation in patients with EC revealed a high prevalence of undetected CVD, inadequately treated pre-existing CVD, and a high incidence of CV events after chemoradiation. These findings highlight the need for a systematic baseline cardiac examination in patients with EC to optimize CVD treatment.

Project description:ObjectiveA comparative assessment of treatment alternatives for T1N0 anal canal cancer has never been conducted. We compared the outcomes associated with the treatment alternatives-chemoradiotherapy (CRT), radiotherapy (RT), and surgery or ablation techniques (surgery/ablation)-for T1N0 anal canal cancer.Materials and methodsThis retrospective cohort study was conducted using the Surveillance, Epidemiology and End Results (SEER) registries linked with Medicare longitudinal data (SEER-Medicare database). Analysis included 190 patients who were treated for T1N0 anal canal cancer using surgery/ablation (n=44), RT (n=50), or CRT (n=96). The outcomes were reported in terms of survival and hazards ratios using Kaplan-Meier and Cox proportional hazards modeling, respectively; lifetime costs; and cost-effectiveness measured in terms of incremental cost-effectiveness ratio, that is, the ratio of the difference in costs between the 2 alternatives to the difference in effectiveness between the same 2 alternatives.ResultsThere was no significant difference in the survival duration between the treatment groups as predicted by the Kaplan-Meier curves. After adjusting for patient characteristics and propensity score, the hazard ratio of death for the patients who received CRT compared with surgery/ablation was 1.742 (95% confidence interval, 0.793-3.829) and RT was 2.170 (95% confidence interval, 0.923-5.101); however, the relationship did not reach statistical significance. Surgery/ablation resulted in lower lifetime cost than RT or CRT. The incremental cost-effectiveness ratio associated with CRT compared with surgery/ablation was $142,883 per life year gained.ConclusionsThere was no statistically significant difference in survival among the treatment alternatives for T1N0 anal canal cancer. Given that surgery/ablation costs less than RT or CRT and might be cost-effective compared with RT and CRT, it is crucial to explore this finding further in this era of limited health care resources.
