Incidence rates and contemporary trends in primary urethral cancer

Abstract Purpose We assessed contemporary incidence rates and trends of primary urethral cancer. Methods We identified urethral cancer patients within Surveillance, Epidemiology and End Results registry (SEER, 2004–2016). Age-standardized incidence rates per 1,000,000 (ASR) were calculated. Log linear regression analyses were used to compute average annual percent change (AAPC). Results From 2004 to 2016, 1907 patients with urethral cancer were diagnosed (ASR 1.69; AAPC: -0.98%, p = 0.3). ASR rates were higher in males than in females (2.70 vs. 0.55), respectively and did not change over the time (both p = 0.3). Highest incidence rates were recorded in respectively ≥75 (0.77), 55–74 (0.71) and ≤54 (0.19) years of age categories, in that order. African Americans exhibited highest incidence rate (3.33) followed by Caucasians (1.72), other race groups (1.57) and Hispanics (1.57), in that order. A significant decrease occurred over time in Hispanics, but not in other race groups. In African Americans, male and female sex-stratified incidence rates were higher than in any other race group. Urothelial histological subtype exhibited highest incidence rate (0.92), followed by squamous cell carcinoma (0.41), adenocarcinoma (0.29) and other histologies (0.20). In stage stratified analyses, T1N0M0 stage exhibited highest incidence rate. However, it decreased over time (−3.00%, p = 0.02) in favor of T1-4N1-2M0 stage (+ 2.11%, p = 0.02). Conclusion Urethral cancer is rare. Its incidence rates are highest in males, elderly patients, African Americans and in urothelial histological subtype. Most urethral cancer cases are T1N0M0, but over time, the incidence of T1N0M0 decreased in favor of T1-4N1-2M0.

Abstract Purpose: We assessed contemporary incidence rates and trends of primary urethral cancer. Methods: We identified urethral cancer patients within Surveillance, Epidemiology and End Results registry (SEER, 2004–2016). Age-standardized incidence rates per 1,000,000 (ASR) were calculated. Log linear regression analyses were used to compute average annual percent change (AAPC). Results: From 2004–2016, 1,907 patients with urethral cancer were diagnosed (ASR 1.69; AAPC: -0.98%, p = 0.3). ASR rates were higher in males than in females (2.70 vs. 0.55), respectively and did not change over the time (both p = 0.3).

Melanoma Incidence

Abstract Background The United States has large regional variation in primary prevention campaigns for skin cancer. We collected data from all 50 states to examine changes in melanoma incidence and performed age-period-cohort analyses to describe the simultaneous effects of age, period, and cohort on incidence rates. Methods Annual melanoma incidence rates for non-Hispanic whites from 2001 to 2015 were extracted from the US Cancer Statistics registry. Secular trends were examined overall and by sex and state. We used joinpoint regression to compute annual percent change and average annual percent change and corresponding 95% confidence intervals (CIs). We also analyzed incidence trends by 5-year age group and birth cohort using incidence rate ratios and age-period-cohort modeling. Results Melanoma incidence increased from 20.7 per 100 000 (95% CI = 20.5 to 20.9) in 2001 to 28.2 per 100 000 (95% CI = 28.0 to 28.5) in 2015, increasing by 3.90% (95% CI = 2.36% to 5.48%) annually between 2001 and 2005 and 1.68% (95% CI = 1.37% to 1.99%) annually from 2005 through 2015. The average annual percent change in melanoma incidence rates were similar for men (2.34%, 95% CI = 1.91 to 2.78) and women (2.25%, 95% CI = 1.60 to 2.91). Age-specific relative risk by birth cohort increased from circa 1921 to 1981 before decreasing. Compared with adults born circa 1956, those born circa 1991 had lower melanoma risk (incidence rate ratio = 0.85; 95% CI = 0.77 to 0.94). Geographic variation was observed; some states still have melanoma rates trending upwards in all birth cohorts. Conclusions The continued increase in melanoma incidence among non-Hispanic whites, particularly in states where rates continue to rise among recent and current birth cohorts, underscores the need for increased public health campaigns aimed at reducing sun exposure.

Examining incidence trends of all cancers combined in order to understand cancer trends can be misleading, as patterns can vary across individual cancer types. This paper highlights findings on trends over time from Canadian Cancer Statistics 2019, as measured by the annual percent change (APC) of age-standardized incidence rates. Among the results were a recent increase in thyroid cancer in males (APC: 6.4%, 1997–2015), as well as decreases in prostate cancer (APC: −9.1%, 2011–2015) and cervical cancer (APC: −3.3%, 2010–2015).

Background/AimsLymphomas are the most frequent neoplasm of the orbit. However, the epidemiology of orbital lymphomas is not well reported. This study aimed to provide a population-based report on the epidemiology of orbital lymphomas and measure the trends in the incidence of orbital lymphoma cancer in South Korea.MethodsNationwide cancer incidence data from 1999 to 2016 were obtained from the Korea Central Cancer Registry. Age-standardised incidence rates and annual percent changes were calculated according to sex and histological types. The analysis according to the Surveillance, Epidemiology, and End Results summary stage classifications was performed from 2006 to 2016. Survival rates were estimated for cases diagnosed from 1999 to 2016.ResultsA total of 630 patients (median age: 54 years) with orbital lymphoma in the orbital soft tissue were included in this study. The age-standardised incidence rates increased from 0.03 to 0.08 per 100 000 individuals between 1999 and 2016, with an annual percent change of 6.61%. The most common histopathological type of orbital lymphoma was extra marginal zone B cell lymphoma, accounting for 82.2% of all orbital lymphomas during 1999–2016, followed by diffuse large B cell lymphoma (9.2%). Five-year, 10-year and 15-year overall survival (OS) of orbital lymphoma was 90.8%, 83.8% and 75.8%, respectively. OS showed a significant decrease as age increased and no significant differences between men and women.ConclusionThe incidence rate of orbital lymphoma is very low in South Korea. However, the incidence rate has increased over the past years. Orbital lymphomas have a worse prognosis as age increases.

BACKGROUND: Bladder cancer (BC) is a common genitourinary malignancy with over 80,000 new cases diagnosed annually and over 17,000 associated deaths. OBJECTIVE: We review 25-years of BC incidence (1993-2017) within the state of Pennsylvania to better define incidence, geographic distribution, and trends over time. METHODS: The Pennsylvania Cancer Registry was reviewed for statewide and component county age-adjusted BC incidence rates and stage distribution. Chloropleth maps plotting statewide and county-specific incidence rates across time were created using the GeoDa statistical package. RESULTS: 93,476 cases of BC were recorded in Pennsylvania from 1993 to 2017. Age-adjusted annual rates of BC over the study interval were stable at 24.5 patients per 100,000 (range, 22.7–25.6). However, annual rates of distant disease increased from 0.5 to 1.1 patients per 100,000 (p < 0.001) with an average percent change increase of 6.6% over the study interval. The annual percent distribution of distant disease doubled from 2.3% to 5.1% (p < 0.001) with a greater increase in women compared to men. Chloropleth maps highlighted growing “hot spots” of bladder cancer incidence in the northwestern, northeastern, and southeastern portions of the state. CONCLUSIONS: While BC incidence in the state of Pennsylvania has remained relatively stable over the past 25 years, a concerning increase in distant disease was observed. Geospatial investigation implicates higher risk regions. Further studies are necessary to delineate the underlying etiologies for these observations.

End Results

Object Primary malignant spinal glioma represents a significant clinical challenge due to the devastating effect on clinical outcomes in the majority of cases. As they are infrequently encountered in any one center, there has been limited population-based data analysis on the incidence patterns of these aggressive tumors. The objective of this study was to use publically available Surveillance, Epidemiology and End Results (SEER) program data to examine the overall incidence and incidence patterns over time with regard to age at diagnosis, sex, race, primary site of tumor, and histological subtype in patients in whom primary malignant spinal cord gliomas were diagnosed between 1973 and 2006. Methods The study population of interest was limited to primary, malignant, pathologically confirmed spinal cord gliomas based on data drawn from the SEER 9 standard registries for patients diagnosed between 1973 and 2006. Variables of interest included age at diagnosis, sex, race, primary site of tumor, and histological subtype of tumor. The SEER*Stat 6.5.2 program was used to calculate frequencies, age-adjusted incidence rates with 95% CIs, and annual percentage change (APC) statistics with a 2-sided p value. In addition, linear correlation coefficients (R2) were calculated for the time association stratified by variables of interest. Results The overall age-adjusted incidence rate for primary malignant spinal gliomas was 0.12 per 100,000, which increased significantly over the study period (APC = 1.74; p = 0.0004; R2 = 0.36). The incidence was highest in patients diagnosed at ages 35–49 (0.17 per 100,000), males (0.14 per 100,000), whites (0.13 per 100,000), and those with ependymomas (0.07 per 100,000). Over the study period, the incidence of ependymomas increased significantly (APC = 3.17; p < 0.0001; R2 = 0.58) as did the incidence of these tumors in whites (APC = 2.13; p = 0.0001) and for both males (APC = 1.90, p value < 0.0001) and females (APC = 1.60, p < 0.0001). The authors found no significant changes in the incidence over time by age of diagnosis. Conclusions This study demonstrates an increasing overall incidence of primary, malignant spinal cord glioma over the past 3 decades. Notably, for ependymoma the incidence has increased, whereas the incidence of most other glioma subtypes remained stable. This may be due to improved diagnostic and surgical techniques, changes in histological classification criteria, and changes in neuropathology diagnostic criteria. Although primary, malignant spinal cord gliomas are rare, an improved understanding of the incidence will assist investigators and clinicians in planning potential studies and preparing for allocation of resources to care for these challenging patients.

Background: Skin cancer is common in North America. Incidence rate trends are potentially important in the assessment of the effects of measures to increase sun awareness in the population as well as measures to reduce sun damage. Objective: To determine the incidence of basal cell carcinoma (BCC), squamous cell carcinoma (SCC), and cutaneous malignant melanoma (CMM) in a geographically defined Canadian population over a 40-year period. Methods: Data were obtained from the BC Cancer Registry for the calendar years 1973, 1983, 1993, and 2003. Results: Age-standardized incidence rates increased significantly from 1973 to 2003 for BCC, SCC, and CMM. Limitations: The ethnic makeup of British Columbia has changed over time, and a novel method of accounting for the effect of this on skin cancer rates is presented. Conclusion: The incidence rate for skin cancers continued to rise in British Columbia, but there appears to have been a decline in the incidence of CMM and BCC in the youngest cohorts.

Object Despite the recognition of racial or ethnic differences in preterm gestation, such differences in the rate of intraventricular hemorrhage (IVH), frequently associated with preterm gestation, are not well studied. The authors performed the current study to identify racial or ethnic differences in the incidence of IVH-related mortality within the national population of the US. Methods Using the ICD-10 codes P52.0, P52.1, P52.2, P52.3, and P10.2 and the Multiple Cause of Death data from 2000 to 2009, the authors identified all IVH-related mortalities that occurred in neonates and infants aged less than 1 year. The live births for whites and African Americans from the census for 2000–2009 were used to derive the incidence of IVH-related mortality for whites and African Americans per 100,000 live births. The IVH rate ratio (RR, 95% confidence interval [CI]) and annual percent change (APC) in the incidence rates from 2000 to 2009 were also calculated. Results A total of 3249 IVH-related mortality cases were reported from 2000 to 2009. The incidence rates of IVH were higher among African American infants (16 per 100,000 live births) than among whites (7.8 per 100,000 live births). African American infants had a 2-fold higher risk of IVH-related mortality compared with whites (RR 2.0, 95% CI 1.2–3.2). The rate of increase over the last 10 years was less in African American infants (APC 1.6%) than in white infants (APC 4.3%). Conclusions The rate of IVH-related mortality is 2-fold higher among African American than white neonates and infants. Further studies are required to understand the underlying reasons for this prominent disparity in one of the most significant causes of infant mortality.

68 Background: Studies show lower rates of hospice use among patients (pts) with hematologic malignancies. Our objective was to describe trends in hospice use and in quality measures for end-of-life (EOL) care among Medicare beneficiaries with leukemias. Methods: From the Surveillance, Epidemiology, and End Results (SEER)-Medicare linked database, we selected pts with acute (myeloid or lymphoblastic) or chronic (lymphocytic, myeloid, or myelomonocytic) leukemias diagnosed in 1996-2011 who died in 2001-2011. We identified hospice enrollment at death, duration of hospice enrollment, inpatient deaths, intensive care unit (ICU) admissions within 30 days of death, and chemotherapy use in the last 14 days of life. We summarized linearized trends by year of death using log-binomial regression, reporting average annual percent change (APC). Results: Among 38,038 leukemia pts (41% acute, median age 78 years) 81% died, after median 2.8 months from diagnosis (95%CI, 2.7-2.9) for acute and 49.1 months (95%CI, 47.9-50.1) for chronic leukemias. Among pts who died in 2001-2011 ( N= 23,941), 42% were enrolled in hospice at the time of death. This proportion significantly increased between 2001 and 2011, from 33% to 48% (APC +4.1%, P< .001), both for acute and chronic leukemias ( Pinteraction= .25). Median time on hospice was 8 days, and the proportion of pts with < 3 days on hospice increased from 20% to 24% between 2001 and 2001 (APC +1.2%, P= .05). Inpatient deaths significantly decreased from 54% to 39%, respectively (APC -3.2%, P< .001), but ICU use at EOL increased from 34% to 41% (APC +2.4%, P< .001). Chemotherapy use at EOL was more frequent in acute (17%) than chronic (6%) leukemia, and decreased for both (overall from 15% to 10%, APC -3.2%, P< .001). Conclusions: The use of hospice services among older pts with leukemia has increased, suggesting its wider acceptance over time. However, the increasing proportion of brief, terminal hospice admissions, and increasing rate of ICU use at EOL reflect persistent barriers to early enrollment in this population. Some measures of aggressiveness of care (inpatient deaths, chemotherapy at EOL) are lower in the community than previously reported from academic centers (El-Jawahri, Cancer 2015).

Variant Hemoglobin

Introduction: Screening for variant hemoglobin is essential in identifying newborns born with hemoglobinopathies, including sickle cell trait (SCT). Screening allows families the opportunity for patient education as well as genetic counseling. This study aimed to better understand the trends in newborn screening of variant hemoglobin in the state of Nebraska over a period of eight years. Methods: Using the Department of Health and Human Services state-level screening information,the crude incidence rate of SCT was calculated as the screened positives divided by the total number of screened newborns within the state of Nebraska from 2011 to 2018. Rates were further delineated by variant. A Daniel's test was utilized to determine if the crude incidence rates exhibited characteristics of a trend. Rates were also examined with joinpoint regression to determine annual percent change (APC). Excel v 1808 and Joinpoint Trend Analysis v 4.5 software packages were used for all analyses; p < 0.05 was considered significant. Results: We identified 3,416 newborns with SCT among a total of 211,697 live births, which is an incidence rate of 161.4 cases per 10,000 screened newborns. There was no evidence of a trend in the overall incidence rate from 2011 to 2018 (p = 0.493). However, the incidence of FA Barts significantly increased over the examined interval (p = 0.015) with a 4.4% APC (95% CI: 0.7% to 8.3%; p =0.026) Conclusion: The data obtained from this study showed no significant change in the incidence of SCT in the state of Nebraska from 2011 to 2018. However, there was a significant increase in the incidence of Hemoglobin FA Barts. Hemoglobin FA Barts is associated primarily with alpha thalassemia, which is most prevalent in southeast Asia, but is also common in the Mediterranean, Africa, Middle east, Central Asia and India. This finding is of interest and likely related to the changing migration patterns in the state of Nebraska. For the healthcare system to continue to provide appropriate care, future studies should aim to further elucidate this trend and patient demographics of this increasing patient population in the state of Nebraska. Disclosures No relevant conflicts of interest to declare.
