Molecular Tumor Board Review and Improved Overall Survival in Non-Small-Cell Lung Cancer.

With the introduction of precision medicine, treatment options for non-small-cell lung cancer have improved dramatically; however, underutilization, especially in disadvantaged patients, like those living in rural Appalachian regions, is associated with poorer survival. Molecular tumor boards (MTBs) represent a strategy to increase precision medicine use. UK HealthCare at the University of Kentucky (UK) implemented a statewide MTB in January 2017. We wanted to test the impact of UK MTB review on overall survival in Appalachian and other regions in Kentucky. METHODS: We performed a case-control study of Kentucky patients newly diagnosed with non-small-cell lung cancer between 2017 and 2019. Cases were reviewed by the UK MTB and were compared with controls without UK MTB review. Controls were identified from the Kentucky Cancer Registry and propensity-matched to cases. The primary end point was the association between MTB review and overall patient survival. RESULTS: Overall, 956 patients were included, with 343 (39%) residing in an Appalachian region. Seventy-seven (8.1%) were reviewed by the MTB and classified as cases. Cox regression analysis showed that poorer survival outcome was associated with lack of MTB review (hazard ratio [HR] = 8.61; 95% CI, 3.83 to 19.31; P < .0001) and living in an Appalachian region (hazard ratio = 1.43; 95% CI, 1.17 to 1.75; P = .004). Among individuals with MTB review, survival outcomes were similar regardless of whether they lived in Appalachia or other parts of Kentucky. CONCLUSION: MTB review is an independent positive predictor of overall survival regardless of residence location. MTBs may help overcome some health disparities for disadvantaged populations.

Uterine Corpus Malignancies in Appalachia Kentucky: Incidence, Survival, and Related Health Disparities.

OBJECTIVES: Uterine cancer is the nation's most common gynecologic malignancy, but it is understudied in the geographically and socioeconomically diverse state of Kentucky (KY). Our aim was to assess the frequency, distribution, and survival of uterine corpus malignancies in KY, and specifically the differences between Appalachia (AP) and non-Appalachia (NAP) KY. METHODS: This population-based cohort study used Surveillance, Epidemiology, and End Results data and the Kentucky Cancer Registry to study uterine corpus malignancy between January 1, 2000 and December 31, 2014. The analysis looked at the incidence between diagnoses in AP and NAP. The evaluation criteria included tumor histology (type I, type II, sarcoma, and mixed uterine malignancy), age, race, smoking status, stage at diagnosis, insurance status, and county of residence at diagnosis. RESULTS: The overall age-adjusted incidence rate and survival are similar for US and KY populations; however, histologic types and distribution differ. Compared with the United States, the incidence of corpus cancers in KY is higher for type I (P = 0.03), but lower for type II (P = 0.003), sarcoma (P = 0.006), and mixed (P < 0.001). AP KY has a higher incidence of type I (P < 0.0001) and mixed malignancy (P = 0.04), younger age at diagnosis (P < 0.0001), larger non-Hispanic white population (P < 0.0001), fewer smokers (P = 0.002), and more uninsured and Medicaid recipients (P < 0.0001) compared with NAP KY. The hazard ratio for death is similar in AP and NAP KY (0.896; 95% confidence interval 0.795-1.009). CONCLUSIONS: Type I and mixed uterine corpus cancers have a higher age-adjusted incidence and a younger age at diagnosis in AP compared with NAP KY.

Survival of Women With Type I and II Epithelial Ovarian Cancer Detected by Ultrasound Screening.

OBJECTIVE: To estimate the effect of ultrasound screening on stage at detection and long-term disease-specific survival of at-risk women with epithelial ovarian cancer. METHODS: Eligibility included all asymptomatic women 50 years of age or older and women 25 years of age or older with a documented family history of ovarian cancer. From 1987 to 2017, 46,101 women received annual ultrasound screening in a prospective cohort trial. Women with a persisting abnormal screen underwent tumor morphology indexing, serum biomarker analysis, and surgery. RESULTS: Seventy-one invasive epithelial ovarian cancers and 17 epithelial ovarian tumors of low malignant potential were detected. No women with a low malignant potential tumor experienced recurrent disease. Stage distribution for screen-detected invasive epithelial ovarian cancers was stage I-30 (42%), stage II-15 (21%), stage III-26 (37%), and stage IV-0 (0%). Follow-up varied from 9.2 months to 27 years (mean 7.9 years). Disease-specific survival at 5, 10, and 20 years for women with invasive epithelial ovarian cancer detected by screening was 86±4%, 68±7%, and 65±7%, respectively, vs 45±2%, 31±2%, and 19±3%, respectively, for unscreened women with clinically detected ovarian cancer from the same geographic area who were treated at the same institution by the same treatment protocols (P<.001). Twenty-seven percent of screen-detected malignancies were type I and 73% were type II. The disease-specific survival of women with type I and type II screen-detected tumors was significantly higher than that of women with clinically detected type I and type II tumors and was related directly to earlier stage at detection. CONCLUSION: Annual ultrasound screening of at-risk asymptomatic women was associated with lower stage at detection and increased 5-, 10-, and 20-year disease-specific survival of women with both type I and type II epithelial ovarian cancer.
