ObjectiveThe benefits of adjuvant radiation treatment after hysterectomy have been confirmed in select patients with early-stage endometrial carcinoma. The goal of this study was to evaluate the prognostic impact of the time interval between hysterectomy and starting adjuvant radiation treatment in patients with early-stage endometrial carcinoma.MethodsOur database was searched for women with early-stage endometrioid endometrial cancer who received adjuvant radiation therapy after hysterectomy. The patients were classified into two groups based on the time interval to adjuvant radiation therapy (≤8 weeks or >8 weeks) after hysterectomy. Recurrence-free survival, disease-specific survival, and overall survival were compared between the two groups.ResultsFour hundred and sixty patients were identified. Median follow-up was 70.5 months (range 1–360). One hundred and seventy-six patients (38%) were 2009 International Federation of Gynecology and Obstetrics stage IA, 207 (45%) stage IB, and 77 (17%) stage II. Three hundred and fifty-four women (77%) received adjuvant radiation therapy within 8 weeks after hysterectomy. There was no statistically significant difference between the two groups in baseline demographics, disease and treatment characteristics, except for the modality of adjuvant radiation therapy. Patients who received adjuvant radiation therapy within 8 weeks experienced significantly less disease recurrence (9% vs 18%; p=0.01) and particularly less isolated vaginal recurrence (0% vs 6%, p=0.04). Five-year recurrence-free survival was 89% versus 80% (p=0.04), 5-year disease-specific survival was 93% for both groups, and 5-year overall survival was 86% versus 85% for patients who received adjuvant radiation therapy ≤8 and >8 weeks, respectively (p=0.88).ConclusionOur study suggests that delaying adjuvant radiation therapy beyond 8 weeks after hysterectomy is associated with significantly more cancer recurrences for women with early-stage endometrial carcinoma.

ABSTRACT Surgery is the standard modality for early-stage I–II non-small-cell lung cancer (NSCLC). Generally, patients who are >80 years old tend to have more comorbidities and inferior physical status than younger patients. Stereotactic body radiation therapy (SBRT) may provide an alternative treatment for this group of patients. Here, we report our experience using SBRT to in the management of early-stage NSCLC in patients >80 years old. Patients aged ≥80 years old who were diagnosed with early-stage NSCLC and treated with definitive lung SBRT from January 2000 to January 2018 were retrospectively analysed. Local recurrence-free survival (LRFS), regional recurrence-free survival (RRFS), cancer-specific survival (CSS), progression-free survival (PFS), overall survival (OS) and treatment-related toxicities were analysed for patients >80 years old. A total of 153 patients were included, with a median age of 85 years (range, 80–94). The median follow-up period and OS was 39.8 months (range, 10–101 months) and 76 months, respectively. The 3-year OS, PFS, CSS, RRFS and LRFS were 65.3, 58.0, 75.7, 73.9 and 85.3%, respectively. Radiation pneumonitis grade 0–1, grade 2, grade 3 and grade 4 was observed in 135 (88.2%), 13 (8.5%), 4 (2.61%) and 1 (0.6%) patient(s), respectively. On multivariate analyses, tumor size, pretreatment C-reactive protein (CRP) value, histology and pretreatment physical state were significantly associated with OS. Definitive lung SBRT appears to have high LRFS and OS without causing high-grade radiation-related toxicities in early-stage NSCLC patients who were >80 years old.
