The risk of death from index- and nonindex-cancers varies widely among primary sites. Risk of noncancer deaths now surpasses that of cancer deaths, particularly for young patients in the year after diagnosis.
Background
There are conflicting data regarding a potential survival benefit to adjuvant whole brain radiotherapy (WBRT) among patients with limited brain metastases treated with stereotactic radiosurgery (SRS). We sought to determine if WBRT is associated with improved overall survival among non-small cell lung cancer (NSCLC) patients with favorable prognoses at diagnosis.
Methods
In the N0574 trial, patients with 1–3 brain metastases were randomized to receive SRS or SRS+WBRT with a primary endpoint of cognitive deterioration. We calculated diagnosis-specific graded prognostic assessment (DS-GPA) scores for NSCLC patients and evaluated overall survival according to receipt of WBRT and DS-GPA score using two separate cut-points (≥ 2.0 vs. <2.0 and ≥ 2.5 vs. < 2.5).
Results
A total of 126 NSCLC patients were included for analysis with median follow up of 14.2 months. Data for DS-GPA calculation was available for 86.3% of all enrolled NSCLC patients. Overall, 50.0% of patients had DS-GPA score ≥ 2.0 and 23.0% of patients had DS-GPA scores ≥ 2.5. The SRS and SRS+WBRT groups were well balanced with regard to prognostic factors. The median survival according to receipt of WBRT was 11.3 months (+WBRT) and 17.9 months (−WBRT) for patients with DS-GPA ≥ 2.0 (favorable prognoses, p=0.63; HR, 0.86; 95%CI, 0.47–1.59). Median survival was 3.7 months (+WBRT) and 6.6 months (−WBRT) for patients with DS-GPA < 2.0 patients (unfavorable prognoses, p=0.85; HR, 0.95; 95%CI, 0.56–1.62). Outcomes according to the receipt of WBRT and DS-GPA remained similar utilizing DS-GPA ≥ 2.5 as a cutoff for favorable prognoses. There was no interaction between the continuum of the DS-GPA groups and WBRT on overall survival (p=0.53).
Conclusions
We observed no significant differences in survival according to receipt of WBRT in favorable prognosis NSCLC patients. This study further supports the approach of SRS alone in the majority of patients with limited brain metastases.
IMPORTANCE Brain metastases are a common source of morbidity for patients with cancer, and limited data exist to support the local therapeutic choice between surgical resection and stereotactic radiosurgery (SRS). OBJECTIVE To evaluate local control of brain metastases among patients treated with SRS vs surgical resection within the European Organization for the Research and Treatment of Cancer (EORTC) 22952-26001 phase 3 trial.
Introduction
Our study sought to characterize the presentation, local management and outcomes of invasive cervical cancer with regard to patient insurance status.
Methods
We queried the NCI-SEER database for invasive cervical cancer cases in patients aged 18–64 from 2007–2011. We analyzed clinical and socioeconomic data with regard insurance status (insured, Medicaid, or uninsured). We tested for associations between patient insurance status and treatment with definitive surgery for FIGO IA2-IB1 patients, and treatment with suboptimal radiation therapy (RT) for FIGO IB2-IVA patients (other than combination external beam and brachytherapy). We evaluated overall and cause specific survival according to insurance status.
Results
11,714 cases were analyzed: 60% insured, 31% Medicaid, and 9% uninsured. FIGO III/IV stage at presentation was more frequent with Medicaid (40%) and uninsured (42%) compared to insured patients (28%) (p<0.001). For FIGO IA2-IB1 patients, receipt of definitive surgery was inversely associated with uninsured status (OR[95%CI]=0.65[0.47–0.90],p<0.001) in univariable analysis; however the relationship lost significance after multivariable adjustment. For FIGO IB2-IVA patients, the use of suboptimal RT was associated with uninsured status (OR[95%CI]=1.33[1.07–1.65],p=0.011) in adjusted analyses. Among all patients, overall mortality was increased with Medicaid (HR[95%CI]=1.16[1.05–1.28],p=0.003) and uninsured status (HR[95%CI]=1.17[1.01–1.34],p=0.031) in multivariable analysis. Cancer specific mortality survival trended towards significance in multivariable analyses for both Medicaid (HR[95%CI]=1.11[1.00–1.24] and uninsured status (HR[95%CI]=1.14[0.98–1.33]).
Conclusions
Disparities in cervical cancer treatment with regard to insurance status are apparent in a recent cohort of American patients. Later stage at presentation and differences in management partially account for the inferior prognostic outcomes associated with Medicaid and uninsured status.
