Cardiac Toxicity in Operable Esophageal Cancer Patients Treated With or Without Chemoradiation.

ABSTRACT: PURPOSE:The purpose of this study was to evaluate predictors of cardiac events in esophageal cancer patients treated with neoadjuvant chemoradiotherapy (NA CRT) followed by surgery compared with surgery alone. MATERIALS AND METHODS:We retrospectively identified patients treated for esophageal cancer between 2006 and 2016. A total of 123 patients were identified; 70 were treated with surgery alone, and 53 were treated with NA CRT. Cardiac events were scored based on Common Terminology Criteria for Adverse Events (version 4.03), and dosimetric data was compiled for all patients who received radiation. Univariate analysis and multivariable analysis (MVA) were performed to identify predictors of cardiac events. Competing risk of death regression was performed to a model the cumulative incidence of cardiac events. RESULTS:The overall rates of grade ?3 cardiac events were 24.5% in the NA CRT group versus 10% in the surgery group (P=0.04). On MVA, use of NA CRT (P<0.01, hazard ratio [HR]: 3.45, 95% confidence interval [CI]: 1.35-9.09) predicted for grade ?3 cardiac events, though no dosimetric variable predicted for grade ?3 cardiac events or overall survival. On MVA, NA CRT predicted for pericardial effusions of any grade (P<0.01, HR: 3.70, 95% CI: 1.67-8.33). The V45?Gy was the most significant predictor of pericardial effusions (P=0.012, HR: 1.03, 95% CI: 1.01-1.06) CONCLUSIONS:: NA CRT significantly increased the rate of grade ?3 cardiac events compared with patients treated with surgery alone. Although no dosimetric parameter predicted for grade ?3 cardiac events or survival, the V45?Gy predicted for pericardial effusions.

Project description:Purpose:Preoperative chemoradiation is being currently evaluated in 2 randomized international trials. However, chemoradiation for gastric cancer can be associated with relatively high rates of acute toxicity. We compared rates of toxicity, toxicity-related events, and oncologic outcomes in patients treated with intensity modulated radiation therapy (IMRT) and those treated with 3-dimensional conformal radiation therapy (3DCRT). Methods and Materials:We retrospectively reviewed records of 202 patients with consecutive gastric cancer treated with preoperative intent radiation therapy at our institution from 1998 to 2018. Patients with gastroesophageal junction involvement and those with metastatic disease were excluded. Eighty-two patients received 3DCRT, and 120 patients received IMRT. The median radiation dose was 45 Gy, and 99% received concurrent chemotherapy. Results:There were no significant differences between the 3DCRT and IMRT groups regarding sex, race, histology, tumor location, histology, or nodal stage. The rate of grade 3 to 4 acute toxicity was significantly lower in patients treated with IMRT compared with 3DCRT (49% vs 70%, P = .004). The composite rate of toxicity-related events (hospitalization, feeding tube use, intravenous rehydration, or radiation therapy breaks) was also significantly lower in patients treated with IMRT compared with 3DCRT (56% vs 85%, P <.001). In addition, 68% of patients who received IMRT and 73% of patients who received 3DCRT underwent subsequent surgical resection (P = .245). Among patients who underwent surgery, the 3-year overall survival rates were not significantly different between those treated with IMRT and 3DCRT (71% vs 69%, P = .786). Patients receiving IMRT had a significantly higher absolute nadir lymphocyte count compared with patients receiving 3DCRT (median, 0.21 vs 0.16 K/UL; P = .047). Conclusions:Our study suggests that IMRT might significantly reduce rates of grade 3 to 4 acute toxicity and toxicity-related events compared with 3DCRT, with no significant difference in oncologic outcomes. IMRT is an appropriate and possibly preferable radiation modality in patients treated with preoperative chemoradiation for gastric 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:Purpose:Hematologic toxicity (HT) during chemoradiation therapy (CRT) for anal cancer can lead to treatment breaks that compromise efficacy. We hypothesized that CRT-induced HT correlates with changes in active bone marrow (ABM) characterized by pre-/post-CRT positron emission tomography (PET)/computed tomography. Methods and materials:Data from 36 patients with anal cancer who were treated with 18F-fluorodeoxyglucose PET/computed tomography scans 2 weeks before and 6 to 16 weeks after CRT were analyzed. Complete blood counts with differential within 2 weeks from, weekly during, and 2 week after treatment were obtained. HT was defined as baseline complete blood count change to nadir and posttreatment recovery. Total bone marrow was segmented into 2 subregions: lumbosacral (LS) pelvis (L5 vertebrae, sacrum, and coccyx) and lower pelvis (LP) (ilium, femoral head/neck, and greater and lesser trochanter). PET ABM was characterized as the volume having standard uptake value (SUV) greater than the mean uptake of unirradiated extrapelvic bone marrow. PET variables of pre-/post-CRT and HT predictors were analyzed by linear regression. Results:Average pelvic ABM was significantly reduced from 52% to 41% in pre- to post-CRT PET scans for all patients (P = .0012). Regional analysis indicated significant post-CRT reduction of LS-ABM (P < .0001) and LP-ABM (P = .006). Linear regression analysis identified post-CRT SUVmean, differential ?SUVmean, and ?ABM as correlating significantly with pre- and posttreatment HT. ?WBC linearly correlated with ?ABM of LS and LP pelvis (P = .033 and P = .028, respectively). Dosimetrically, ABM was sensitive to higher radiation doses (>50 Gy) in terms of acute hematologic ?WBC (P = .021) and ?ANC(P = .028). HT increased with increasing volume of ABM receiving 40 Gy. The results also suggest that ABM V40 Gy ? 20% to 25% may significantly reduce the risk of HT. Conclusions:HT was significantly associated with ?ABM in patients with anal cancer who were treated with CRT. LS-ABM was a robust surrogate for evaluating CRT-induced HT. Our results suggest implementation of ABM dosimetric constraints, V40 Gy ? 20-25%, may significantly reduce HT and lead to decreased treatment delays associated with clinical outcomes.
