Decreasing Trends of Secondary Primary Colorectal Cancer among Women with Uterine Cancer: A Population-Based Analysis.

ABSTRACT: The current study examined trends, characteristics, and outcomes of women with uterine cancer who had secondary colorectal cancer. This is a retrospective study utilizing the Surveillance, Epidemiology, and End Results Program between 1973-2013. Among uterine cancer (n = 246,272) and colorectal cancer (n = 421,312) cohorts, women with both diagnoses were identified, and clinico-pathological factors and survival were extracted and analyzed. There were 6862 women with both cancer diagnoses, representing 2.8% of the uterine cancer cohort and 1.6% of the colorectal cancer cohort. Among 123,940 women with uterine cancer survivors, the number with postcedent colorectal cancer decreased from 5.3% to 0.7% between 1981-2008 (relative risk reduction 87.0% p < 0.001). Similarly, of 141,801 women with colorectal cancer survivors, the number with postcedent uterine cancer decreased from 1.7% to 0.5% between 1973-2008 (relative risk reduction 71.6%, p < 0.001). In the uterine cancer cohort, women with antecedent/synchronous colorectal cancer had more high-grade tumors and advanced-stage disease resulting in poorer survival, whereas those who had postcedent colorectal cancer had more low-grade tumors and early-stage disease resulting in superior survival compared to those without secondary colorectal cancer (all, p < 0.05). In conclusion, the development of postcedent colorectal cancer following uterine cancer has decreased in recent years in the United States.

Project description:PurposeThis study aimed to profile the characteristics of patients with colorectal cancer (CRC) with a second primary malignancy (SPM) and to identify patients with CRC at high risk of developing SPMs.MethodsWe retrospectively reviewed data on patients with CRC aged 20-79 years from the Surveillance, Epidemiology, and End Results (SEER) database. Eligible patients were categorized into only one primary malignancy and SPM cohorts. A competing-risk model was used to quantify associations between SPM occurrence and the multiple traits of patients. Finally, a decision curve analysis (DCA) was used to evaluate the clinical usefulness of the model by calculating net benefit.ResultsA total of 179,884 patients were identified, 18,285 (10.2%) of whom developed SPMs during a maximum follow-up of approximately 18 years. The median survival time after the second diagnosis was less than 4 years. The 3-year, 5-year, and 10-year cumulative risks of developing an SPM were 3.9%, 5.9%, and 10.0%, respectively. According to the multivariable competing-risk model, male colon cancer survivors, older in age, with a well-differentiated tumor and localized disease, who were treated with surgery were susceptible to SPMs. The DCA yielded a wide range of risk thresholds at which the net benefits would be obtained from our proposed model.ConclusionCRC survivors remain at high risk of developing SPMs. Patients with a second diagnosis of cancer showed not only significantly worse survival but also higher cancer-specific mortality. A web-based individualized predictive tool was also provided to assist clinicians in identifying patients at high risk of developing SPMs and planning their future care management.Implications for practiceColorectal cancer survivors remain at high risk of developing a second primary malignancy (SPM). This study aimed to profile the characteristics of patients with colorectal cancer with second primary malignancies and to further explore the risk factors related to the development of second primary malignancies, using a large population-based cohort. A clinically useful competing-risk nomogram was developed to predict the risk of SPMs based on individual clinical factors. According to the findings, older age, male sex, white or black race, localized disease, and treatment with surgery among patients with colon cancer were associated with an increased risk of developing an SPM. These findings and the proposed tool could be useful to clinicians and caregivers in the clinical counseling of patients with colorectal cancer and the development of long-term care management.

Project description:BackgroundAntimicrobial overuse and misuse of broad-spectrum antibiotics increases the risk for antimicrobial resistance. Investigating unwarranted variation in antibiotic prescription has therefore gained global priority.MethodsWe examined recent time trends in the utilization of narrow- and broad-spectrum antibiotics as well as the variation in antibiotic use by sex, age, and municipality of residence. Complete individual-level data on all redeemed out-of hospital prescriptions for antibiotics in the entire adult population of Central Denmark (1.3 million inhabitants) was obtained for the period 2006-2015.ResultsFollowing an initial increase of 2% between 2006 and 2011, the overall rate of redeemed prescriptions for antibiotics per 1000 person years declined by 17% between 2011 and 2015. Among persons aged over 65 years, the decline in use began later (from 2013) and was less pronounced. Antibiotic use in 2015 remained substantially higher among females (289/1000 person-years) vs. males (182/1000 person-years) and among the very old (520/1000 person-years in >85y old) vs. middle-aged (204/1000 person-years in 45-65y old). A decreasing trend in antibiotic use over time was observed in all municipalities, mainly due to a decrease in narrow-spectrum antibiotics. However, a striking and unexplained 1.6-fold geographical variation in antibiotic use, including tetracyclines, macrolides and fluoroquinolones remained in 2015. Of concern, among females aged ≥65 years and males aged ≥85 years, a continuous increasing trend in broad-spectrum antibiotic use was observed.ConclusionsAntibiotic use has decreased almost 20% in Central Denmark after 2011, possibly related to a nationwide antibiotic stewardship program in Denmark. However, substantial geographical variation in antibiotic prescription remains and the use of broad-spectrum antibiotics has increased in adults of older age. Continuous focus on avoiding unnecessary use of broad-spectrum antibiotics is requested.

Project description:BACKGROUND:High-intensity care including hospitalizations, chemotherapy, and other interventions at the end of life is costly and often of little value for cancer patients. Little is known about patterns of end-of-life care and resource utilization for women with uterine cancer. OBJECTIVE:We examined the costs and predictors of aggressive end-of-life care for women with uterine cancer. STUDY DESIGN:In this observational cohort study the Surveillance, Epidemiology, and End Results-Medicare linked database was used to identify women age ?65 years who died from uterine cancer from 2000 through 2011. Resource utilization in the last month of life including ?2 hospital admissions, >1 emergency department visit, ?1 intensive care unit admission, or use of chemotherapy in the last 14 days of life was examined. High-intensity care was defined as the occurrence of any of the above outcomes. Logistic regression models were developed to identify factors associated with high-intensity care. Total Medicare expenditures in the last month of life are reported. RESULTS:Of the 5873 patients identified, the majority had stage IV cancer (30.2%), were white (79.9%), and had endometrioid tumors (47.6%). High-intensity care was rendered to 42.5% of women. During the last month of life, 15.0% had ?2 hospital admissions, 9.0% had a hospitalization >14 days, 15.3% had >1 emergency department visits, 18.3% had an intensive care unit admission, and 6.6% received chemotherapy in the last 14 days of life. The percentage of women who received high-intensity care was stable over the study period. Characteristics of younger age, black race, higher number of comorbidities, stage IV disease, residence in the eastern United States, and more recent diagnosis were associated with high-intensity care. The median Medicare payment during the last month of life was $7645. Total per beneficiary Medicare payments remained stable from $9656 (interquartile range $3190-15,890) in 2000 to $9208 (interquartile range $3309-18,554) by 2011. The median health care expenditure was 4 times as high for those who received high-intensity care compared to those who did not (median $16,173 vs $4099). CONCLUSION:Among women with uterine cancer, high-intensity care is common in the last month of life, associated with substantial monetary expenditures, and does not appear to be decreasing.
