RESUMEN
BACKGROUND: Precision medicine has become a mainstay of cancer care in recent years. The National Cancer Institute (NCI) Surveillance, Epidemiology, and End Results (SEER) Program has been an authoritative source of cancer statistics and data since 1973. However, tumor genomic information has not been adequately captured in the cancer surveillance data, which impedes population-based research on molecular subtypes. To address this, the SEER Program has developed and implemented a centralized process to link SEER registries' tumor cases with genomic test results that are provided by molecular laboratories to the registries. METHODS: Data linkages were carried out following operating procedures for centralized linkages established by the SEER Program. The linkages used Match*Pro, a probabilistic linkage software, and were facilitated by the registries' trusted third party (an honest broker). The SEER registries provide to NCI limited datasets that undergo preliminary evaluation prior to their release to the research community. RESULTS: Recently conducted genomic linkages included OncotypeDX Breast Recurrence Score, OncotypeDX Breast Ductal Carcinoma in Situ, OncotypeDX Genomic Prostate Score, Decipher Prostate Genomic Classifier, DecisionDX Uveal Melanoma, DecisionDX Preferentially Expressed Antigen in Melanoma, DecisionDX Melanoma, and germline tests results in Georgia and California SEER registries. CONCLUSIONS: The linkages of cancer cases from SEER registries with genomic test results obtained from molecular laboratories offer an effective approach for data collection in cancer surveillance. By providing de-identified data to the research community, the NCI's SEER Program enables scientists to investigate numerous research inquiries.

BACKGROUND: Management of localized or recurrent prostate cancer since the 1990s has been based on risk stratification using clinicopathological variables, including Gleason score, T stage (based on digital rectal exam), and prostate-specific antigen (PSA). In this study a novel prognostic test, the Decipher Prostate Genomic Classifier (GC), was used to stratify risk of prostate cancer progression in a US national database of men with prostate cancer. METHODS: Records of prostate cancer cases from participating SEER (Surveillance, Epidemiology, and End Results) program registries, diagnosed during the period from 2010 through 2018, were linked to records of testing with the GC prognostic test. Multivariable analysis was used to quantify the association between GC scores or risk groups and use of definitive local therapy after diagnosis in the GC biopsy-tested cohort and postoperative radiotherapy in the GC-tested cohort as well as adverse pathological findings after prostatectomy. RESULTS: A total of 572â545 patients were included in the analysis, of whom 8927 patients underwent GC testing. GC biopsy-tested patients were more likely to undergo active active surveillance or watchful waiting than untested patients (odds ratio [OR] =2.21, 95% confidence interval [CI] = 2.04 to 2.38, P < .001). The highest use of active surveillance or watchful waiting was for patients with a low-risk GC classification (41%) compared with those with an intermediate- (27%) or high-risk (11%) GC classification (P < .001). Among National Comprehensive Cancer Network patients with low and favorable-intermediate risk, higher GC risk class was associated with greater use of local therapy (OR = 4.79, 95% CI = 3.51 to 6.55, P < .001). Within this subset of patients who were subsequently treated with prostatectomy, high GC risk was associated with harboring adverse pathological findings (OR = 2.94, 95% CI = 1.38 to 6.27, P = .005). Use of radiation after prostatectomy was statistically significantly associated with higher GC risk groups (OR = 2.69, 95% CI = 1.89 to 3.84). CONCLUSIONS: There is a strong association between use of the biopsy GC test and likelihood of conservative management. Higher genomic classifier scores are associated with higher rates of adverse pathology at time of surgery and greater use of postoperative radiotherapy.In this study the Decipher Prostate Genomic Classifier (GC) was used to analyze a US national database of men with prostate cancer. Use of the GC was associated with conservative management (ie, active surveillance). Among men who had high-risk GC scores and then had surgery, there was a 3-fold higher chance of having worrisome findings in surgical specimens.

Animals face many natural challenges, and humans have added to this burden by applying potentially harmful herbicides and unintentionally introducing competitors. We examine the recently introduced Velarifictorus micado Japanese burrowing cricket which shares the same microhabitat and mating season as the native Gryllus pennsylvanicus field cricket. In this study, we assess the combined effects of Roundup (glyphosate-based herbicide) and a lipopolysaccharide (LPS) immune challenge on both crickets. In both species, an immune challenge reduced the numbers of eggs that the female laid; however, this effect was much larger in G. pennsylvanicus. Conversely, Roundup caused both species to increase egg production, potentially representing a terminal investment strategy. When exposed to both an immune challenge and herbicide, G. pennsylvanicus fecundity was harmed more than V. micado fecundity. Furthermore, V. micado females laid significantly more eggs than G. pennsylvanicus, suggesting that introduced V. micado may have a competitive edge in fecundity over native G. pennsylvanicus. LPS and Roundup each had differing effects on male G. pennsylvanicus and V. micado calling effort. Overall, introduced male V. micado spent significantly more time calling than native G. pennsylvanicus, which could potentially facilitate the spread of this introduced species. Despite the population-level spread of introduced V. micado, in our study, this species did not outperform native G. pennsylvanicus in tolerating immune and chemical challenge. Although V. micado appears to possess traits that make this introduced species successful in colonizing new habitats, it may be less successful in traits that would allow it to outcompete a native species.

STUDY QUESTION: Is there an association between fertility status, method of conception and the risks of birth defects and childhood cancer? SUMMARY ANSWER: The risk of childhood cancer had two independent components: (i) method of conception and (ii) presence, type and number of birth defects. WHAT IS KNOWN ALREADY: The rarity of the co-occurrence of birth defects, cancer and ART makes studying their association challenging. Prior studies have indicated that infertility and ART are associated with an increased risk of birth defects or cancer but have been limited by small sample size and inadequate statistical power, failure to adjust for or include plurality, differences in definitions and/or methods of ascertainment, lack of information on ART treatment parameters or study periods spanning decades resulting in a substantial historical bias as ART techniques have improved. STUDY DESIGN, SIZE, DURATION: This was a population-based cohort study linking ART cycles reported to the Society for Assisted Reproductive Technology Clinic Outcome Reporting System (SART CORS) from 1 January 2004 to 31 December 2017 that resulted in live births in 2004-2018 in Massachusetts and North Carolina and live births in 2004-2017 in Texas and New York. A 10:1 sample of non-ART births were chosen within the same time period as the ART birth. Non-ART siblings were identified through the ART mother's information. Children from non-ART births were classified as being born to women who conceived with ovulation induction or IUI (OI/IUI) when there was an indication of infertility treatment on the birth certificate, and the woman did not link to the SART CORS; all others were classified as being naturally conceived. PARTICIPANTS/MATERIALS, SETTING, METHODS: The study population included 165â125 ART children, 31â524 non-ART siblings, 12â451 children born to OI/IUI-treated women and 1â353â440 naturally conceived children. All study children were linked to their respective State birth defect registries to identify major defects diagnosed within the first year of life. We classified children with major defects as either chromosomal (i.e. presence of a chromosomal defect with or without any other major defect) or nonchromosomal (i.e. presence of a major defect but having no chromosomal defect), or all major defects (chromosomal and nonchromosomal), and calculated rates per 1000 children. Logistic regression models were used to generate adjusted odds ratios (AORs) and 95% CIs of the risk of birth defects by conception group (OI/IUI, non-ART sibling and ART by oocyte source and embryo state) with naturally conceived children as the reference, adjusted for paternal and maternal ages; maternal race and ethnicity, education, BMI, parity, diabetes, hypertension; and for plurality, infant sex and State and year of birth. All study children were also linked to their respective State cancer registries. Cox proportional hazards regression models were used to estimate hazard ratios (HRs) and 95% CIs of cancer by birth defect status (including presence of a defect, type and number of defects), and conception group. MAIN RESULTS AND THE ROLE OF CHANCE: A total of 29â571 singleton children (2.0%) and 3753 twin children (3.5%) had a major birth defect (chromosomal or nonchromosomal). Children conceived with ART from autologous oocytes had increased risks for nonchromosomal defects, including blastogenesis, cardiovascular, gastrointestinal and, for males only, genitourinary defects, with AORs ranging from 1.22 to 1.85; children in the autologous-fresh group also had increased risks for musculoskeletal (AOR 1.28, 95% CI 1.13, 1.45) and orofacial defects (AOR 1.40, 95% CI 1.17, 1.68). Within the donor oocyte group, the children conceived from fresh embryos did not have increased risks in any birth defect category, whereas children conceived from thawed embryos had increased risks for nonchromosomal defects (AOR 1.20, 95% CI 1.03, 1.40) and blastogenesis defects (AOR 1.74, 95% CI 1.14, 2.65). The risk of cancer was increased among ART children in the autologous-fresh group (HR 1.31, 95% CI 1.08, 1.59) and non-ART siblings (1.34, 95% CI 1.02, 1.76). The risk of leukemia was increased among children in the OI/IUI group (HR 2.15, 95% CI 1.04, 4.47) and non-ART siblings (HR 1.63, 95% CI 1.02, 2.61). The risk of central nervous system tumors was increased among ART children in the autologous-fresh group (HR 1.68, 95% CI 1.14, 2.48), donor-fresh group (HR 2.57, 95% CI 1.04, 6.32) and non-ART siblings (HR 1.84, 95% CI 1.12, 3.03). ART children in the autologous-fresh group were also at increased risk for solid tumors (HR 1.39, 95% CI 1.09, 1.77). A total of 127 children had both major birth defects and cancer, of which 53 children (42%) had leukemia. The risk of cancer had two independent components: (i) method of conception (described above) and (ii) presence, type and number of birth defects. The presence of nonchromosomal defects increased the cancer risk, greater for two or more defects versus one defect, for all cancers and each type evaluated. The presence of chromosomal defects was strongly associated with cancer risk (HR 8.70 for all cancers and HR 21.90 for leukemia), further elevated in the presence of both chromosomal and nonchromosomal defects (HR 21.29 for all cancers, HR 64.83 for leukemia and HR 4.71 for embryonal tumors). Among the 83â946 children born from ART in the USA in 2019 compared to their naturally conceived counterparts, these risks translate into an estimated excess of 761 children with major birth defects, 31 children with cancer and 11 children with both major birth defects and cancer. LIMITATIONS, REASONS FOR CAUTION: In the SART CORS database, it was not possible to differentiate method of embryo freezing (slow freezing versus vitrification), and data on ICSI were only available in the fresh embryo ART group. In the OI/IUI group, it was not possible to differentiate type of non-ART treatment utilized, and in both the ART and OI/IUI groups, data were unavailable on duration of infertility. Since OI/IUI is underreported on the birth certificate, some OI/IUI children were likely included among the naturally conceived children, which will decrease the difference between all the groups and the naturally conceived children. WIDER IMPLICATIONS OF THE FINDINGS: The use of ART is associated with increased risks of major nonchromosomal birth defects. The presence of birth defects is associated with greater risks for cancer, which adds to the baseline risk in the ART group. Although this study does not show causality, these findings indicate that children conceived with ART, non-ART siblings, and all children with birth defects should be monitored more closely for the subsequent development of cancer.

BACKGROUND: Lung cancer is a common cancer in people living with HIV, but the risk of cancer in this group has not been investigated for over a decade. We investigated trends in relative and absolute risk of lung cancer among people living with HIV of various age groups in the USA. METHODS: In this population-based registry linkage study, we used 2001-16 data from the HIV/AIDS Cancer Match study, which links data from HIV and cancer registries from 13 regions in the USA. We included non-Hispanic White, non-Hispanic Black, and Hispanic individuals living with HIV aged 20-89 years in our study population. Average annual percentage changes in lung cancer rates were estimated with multivariable Poisson regression, and standardised incidence ratios (SIRs) and excess absolute risks were estimated comparing people living with HIV with the general US population. We used non-parametric cumulative incidence curves to estimate the 5-year cumulative incidence of lung cancer and two AIDS-defining cancers (non-Hodgkin lymphoma and Kaposi sarcoma). FINDINGS: There were 3426 lung cancers in 4â310â304 person-years of follow-up in our study population. Age-standardised lung cancer incidence rates in people living with HIV declined by 6% per year (95% CI -7 to -5) during 2001-16, with greater declines in the 20-29 age group (-11%, -16 to 6) than in the older age groups (eg, -3% [-6 to 1] in those aged 70-89 years). During 2013-16, the SIR of lung cancer in people living with HIV was 2·01 (95% CI 1·52 to 2·61) in those aged 40-49 years, and 1·31 (1·12 to 1·52) in those aged 60-69 years, whereas the excess absolute risk among people living with HIV was 11·87 (3·95 to 21·89) per 100â000 person-years for those aged 40-49 years and 48·23 (6·88 to 95·47) per 100â000 person-years for those aged 60-69 years. Beginning in 2011, the 5-year cumulative incidence for lung cancer (1·36%, 95% CI 1·17 to 1·53) surpassed that of Kaposi sarcoma (0·12%, 0·06 to 0·17) and non-Hodgkin lymphoma (0·45%, 0·35 to 0·56) for people living with HIV aged 60-69 years. INTERPRETATION: Between 2001 and 2016, the risk of lung cancer decreased for people living with HIV aged 20-69 years, but remained substantially elevated compared with the general population, probably due to a combination of smoking and immunosuppression. For people living with HIV aged 60 years and older, the risk of lung cancer exceeds that of two of the most common AIDS-defining cancers, highlighting the importance of lung cancer among the growing older population of people living with HIV.

BACKGROUND: Testing for BRCA1/2 pathogenic variants is recommended for women aged ≤45 years with breast cancer. Some studies have found racial/ethnic and socioeconomic disparities in testing. We linked Massachusetts' All-Payer Claims Database with Massachusetts Cancer Registry data to assess factors associated with BRCA1/2 testing among young women with breast cancer in Massachusetts, a state with high levels of access to care and equitable insurance coverage of breast cancer gene (BRCA) testing. METHODS: We identified breast cancer diagnoses in the Massachusetts Cancer Registry from 2010 to 2013 and linked registry data with Massachusetts All-Payer Claims Data from 2010 to 2014 among women aged ≤45 years with private insurance or Medicaid. We used multivariable logistic regression to examine factors associated with BRCA1/2 testing within 6 months of diagnosis. RESULTS: The study population included 2424 women; 80.3% were identified as non-Hispanic White, 6.4% non-Hispanic Black, and 6.3% Hispanic. Overall, 54.9% received BRCA1/2 testing within 6 months of breast cancer diagnosis. In adjusted analyses, non-Hispanic Black women had less than half the odds of testing compared with non-Hispanic White women (adjusted odds ratio [OR] = 0.45, 95% CI = 0.31, 0.64). Medicaid-insured women had half the odds of testing compared with privately-insured women (OR = 0.51, 95% CI = 0.41, 0.63). Living in lower-income areas was also associated with lower odds of testing. Having an academically-affiliated oncology clinician was not associated with testing. CONCLUSION: Socioeconomic and racial/ethnic disparities exist in BRCA1/2 testing among women with breast cancer in Massachusetts, despite equitable insurance coverage of testing. Further research should examine whether disparities have persisted with growing testing awareness and availability over time.

PURPOSE: To investigate assisted reproductive technology (ART) outcomes among adolescent and young-adult female cancer survivors. METHODS: The Society for Assisted Reproductive Technology Clinic Outcome Reporting System (SART CORS) data were linked to the Massachusetts Cancer Registry for 90,928 ART cycles in Massachusetts to women ≥ 18 years old from 2004 to 2013. To estimate relative risks (RR) and 95% confidence intervals (CI), we used generalized estimating equations with a log link that accounted for multiple cycles per woman and a priori adjusted for maternal age and cycle year. The main outcomes of interest were ART treatment patterns; number of autologous oocytes retrieved, fertilized, and transferred; and rates of implantation, clinical intrauterine gestation (CIG), live birth, and pregnancy loss. RESULTS: We saw no difference in number of oocytes retrieved (aRR: 0.95 (0.89-1.02)) or proportion of autologous oocytes fertilized (aRR: 0.99 (0.95-1.03)) between autologous cycles with and without a history of cancer; however, cancer survivors required a higher total FSH administered (aRR: 1.12 (1.06-1.19)). Among autologous cycle starts, cycles in women with a history of cancer were less likely to result in CIG compared to no history of cancer (aRR: 0.73 (0.65-0.83)); this relationship was absent from donor cycles (aRR: 1.01 (0.85-1.20)). Once achieving CIG, donor cycles for women with a history of cancer were two times more likely to result in pregnancy loss (aRR: 1.99 (1.26-3.16)). CONCLUSIONS: Our analysis suggests that cancer may influence ovarian stimulation response, requiring more FSH and resulting in lower CIG among cycle starts.

Variation in development time can affect life-history traits that contribute to fitness. In Gryllus vocalis, a non-diapausing cricket with variable development time, we used a path analysis approach to determine the causative relationships between parental age, offspring development time and offspring life-history traits. Our best-supported path model included both the effects of parental age and offspring development time on offspring morphological traits. This result suggests that offspring traits are influenced by both variation in acquisition of resources and trade-offs between traits. We found that crickets with longer development times became larger adults with better phenoloxidase-based immunity. This is consistent with the hypothesis that crickets must make a trade-off between developing quickly to avoid predation before reproduction and attaining better immunity and a larger adult body size that provides advantages in male-male competition, mate choice and female fecundity. Slower-developing crickets were also more likely to be short-winged (unable to disperse by flight). Parental age has opposing direct and indirect effects on the body size of daughters, but when both the direct and indirect effects of parental age are taken into account, younger parents had smaller sons and daughters. This pattern may be attributable to a parental trade-off between the number and size of eggs produced with younger parents producing more eggs with fewer resources per egg. The relationships between variables in the life-history traits of sons and daughters were similar, suggesting that parental age and development time had similar causative effects on male and female life-history traits.

BACKGROUND: Massachusetts is a northeastern state with universally mandated health insurance since 2006. Although Black men have generally worse prostate cancer outcomes, emerging data suggest that they may experience equivalent outcomes within a fully insured system. In this setting, the authors analyzed treatments and outcomes of non-Hispanic White and Black men in Massachusetts. METHODS: White and Black men who were 20 years old or older and had been diagnosed with localized intermediate- or high-risk nonmetastatic prostate cancer in 2004-2015 were identified in the Massachusetts Cancer Registry. Adjusted logistic regression models were used to assess predictors of definitive therapy. Adjusted and unadjusted survival models compared cancer-specific mortality. Interaction terms were then used to assess whether the effect of race varied between counties. RESULTS: A total of 20,856 men were identified. Of these, 19,287 (92.5%) were White. There were significant county-level differences in the odds of receiving definitive therapy and survival. Survival was worse for those with high-risk cancer (adjusted hazard ratio [HR], 1.50; 95% CI, 1.4-1.60) and those with public insurance (adjusted HR for Medicaid, 1.69; 95% CI, 1.38-2.07; adjusted HR for Medicare, 1.2; 95% CI, 1.14-1.35). Black men were less likely to receive definitive therapy (adjusted odds ratio, 0.78; 95% CI, 0.74-0.83) but had a 17% lower cancer-specific mortality (adjusted HR, 0.83; 95% CI, 0.7-0.99). CONCLUSIONS: Despite lower odds of definitive treatment, Black men experience decreased cancer-specific mortality in comparison with White men in Massachusetts. These data support the growing body of research showing that Black men may achieve outcomes equivalent to or even better than those of White men within the context of a well-insured population. LAY SUMMARY: There is a growing body of evidence showing that the excess risk of death among Black men with prostate cancer may be caused by disparities in access to care, with few or no disparities seen in universally insured health systems such as the Veterans Affairs and US Military Health System. Therefore, the authors sought to assess racial disparities in prostate cancer in Massachusetts, which was the earliest US state to mandate universal insurance coverage (in 2006). Despite lower odds of definitive treatment, Black men with prostate cancer experience reduced cancer-specific mortality in comparison with White men in Massachusetts. These data support the growing body of research showing that Black men may achieve outcomes equivalent to or even better than those of White men within the context of a well-insured population.

PURPOSE: Investigate the relationship between history of cancer and adverse pregnancy outcomes according to subfertility/fertility treatment. METHODS: Deliveries (2004-2013) from Massachusetts (MA) Registry of Vital Records and Statistics were linked to MA assisted reproductive technology data, hospital discharge records, and Cancer Registry. The relative risks (RR) and 95% confidence intervals of adverse outcomes (gestational diabetes (GDM), gestational hypertension (GHTN), cesarean section (CS), low birth weight (LBW), small for gestational age (SGA), preterm birth (PTB), neonatal mortality, and prolonged neonatal hospital stay) were modeled with log-link and Poisson distribution generalized estimating equations. Differences by history of subfertility/fertility treatment were investigated with likelihood ratio tests. RESULTS: Among 662,630 deliveries, 2,983 had a history of cancer. Women with cancer history were not at greater risk of GDM, GHTN, or CS. However, infants born to women with prior cancer had higher risk of LBW (RR: 1.19 [1.07-1.32]), prolonged neonatal hospital stay (RR: 1.16 [1.01-1.34]), and PTB (RR: 1.19 [1.07-1.32]). We found clinically and statistically significant differences in the relationship between cancer history and SGA by subfertility/fertility treatment (p value, test for heterogeneity = 0.02); among deliveries with subfertility or fertility treatment, those with a history of cancer experienced a greater risk of SGA (RRsubfertile: 1.36 [1.02-1.83]). CONCLUSIONS: Women with a history of cancer had greater risk of some adverse pregnancy outcomes; this relationship varied by subfertility and fertility treatment.

PURPOSE: In cancer patients, cigarette smoking is causally linked with increased mortality. We examined the relationship between smoking status at the time of diagnosis and cancer mortality to help estimate the scope of smoking cessation services required to meet the needs of cancer patients. METHODS: We studied the ten most common cancers in Massachusetts, 2008-2013 including 175,489 incident cases and used smoking status at the time of diagnosis to provide smoking prevalence. We calculated adjusted hazard ratios of all-cause mortality comparing smoker subgroups. RESULTS: Smoking prevalence was more than threefold higher for lung cancer and more than twofold higher for head and neck cancer and bladder cancer than in the general population. Cancer cases who smoked at the time of diagnosis had a higher adjusted mortality rate than cancer cases who were former smokers. The three sites with the highest increased hazard ratios comparing current smokers with former smokers were cancers of the thyroid (HR = 1.67, 95% CI 1.14-2.45), head and neck (HR = 1.65, 95% CI 1.39-1.95), and prostate (HR = 1.60, 95% CI 1.36-1.90). CONCLUSIONS: Smoking remains high among cancer patients. More widespread adoption of smoking cessation programs among cancer patients may play a substantial role in improving cancer morbidity and mortality.

Importance: Children with birth defects have a greater risk of developing cancer, but this association has not yet been evaluated in children conceived with in vitro fertilization (IVF). Objective: To assess whether the association between birth defects and cancer is greater in children conceived via IVF compared with children conceived naturally. Design, Setting, and Participants: This cohort study of live births, birth defects, and cancer from Massachusetts, New York, North Carolina, and Texas included 1â¯000â¯639 children born to fertile women and 52â¯776 children conceived via IVF (using autologous oocytes and fresh embryos) during 2004-2016 in Massachusetts and North Carolina, 2004-2015 in New York, and 2004-2013 in Texas. Children were followed up for an average of 5.7 years (6â¯008â¯985 total person-years of exposure). Data analysis was conducted from April 1 to August 31, 2020. Exposures: Conception by IVF for state residents who gave birth to liveborn singletons during the study period. Birth defect diagnoses recorded by statewide registries. Main Outcomes and Measures: Cancer diagnosis as recorded by state cancer registries. Cox proportional hazards regression models were used to estimate hazard ratios (HRs) and 95% CIs for birth defect-cancer associations separately in fertile and IVF groups. Results: A total of 1â¯000â¯639 children (51.3% boys; 69.7% White; and 38.3% born between 2009-2012) were in the fertile group and 52â¯776 were in the IVF group (51.3% boys; 81.3% White; and 39.6% born between 2009-2012). Compared with children without birth defects, cancer risks were higher among children with a major birth defect in the fertile group (hazard ratio [HR], 3.15; 95% CI, 2.40-4.14) and IVF group (HR, 6.90; 95% CI, 3.73-12.74). The HR of cancer among children with a major nonchromosomal defect was 2.07 (95% CI, 1.47-2.91) among children in the fertile group and 4.04 (95% CI, 1.86-8.77) among children in the IVF group. The HR of cancer among children with a chromosomal defect was 15.45 (95% CI, 10.00-23.86) in the fertile group and 38.91 (95% CI, 15.56-97.33) in the IVF group. Conclusions and Relevance: This study found that among children with birth defects, those conceived via IVF were at greater risk of developing cancer compared with children conceived naturally.

INTRODUCTION: The number of cancer cases in the United States continues to grow as the number of older adults increases. Accurate, reliable and detailed incidence data are needed to respond effectively to the growing human costs of cancer in an aging population. The purpose of this study was to examine the characteristics of incident cases and evaluate the impact of death-certificate-only (DCO) cases on cancer incidence rates in older adults. METHODS: Using data from 47 cancer registries and detailed population estimates from the Surveillance, Epidemiology and End Results (SEER) Program, we examined reporting sources, methods of diagnosis, tumor characteristics, and calculated age-specific incidence rates with and without DCO cases in adults aged 65 through ≥95 years, diagnosed 2011 through 2015, by sex and race/ethnicity. RESULTS: The percentage of cases (all cancers combined) reported from a hospital decreased from 90.6% (ages 65-69 years) to 69.1% (ages ≥95 years) while the percentage of DCO cases increased from 1.1% to 19.6%. Excluding DCO cases, positive diagnostic confirmation decreased as age increased from 96.8% (ages 65-69 years) to 69.2% (ages ≥95 years). Compared to incidence rates that included DCO cases, rates in adults aged ≥95 years that excluded DCO cases were 41.5% lower in Black men with prostate cancer and 29.2% lower in Hispanic women with lung cancer. DISCUSSION: Loss of reported tumor specificity with age is consistent with fewer hospital reports. However, the majority of cancers diagnosed in older patients, including those aged ≥95 years, were positively confirmed and were reported with known site, histology, and stage information. The high percentage of DCO cases among patients aged ≥85 years suggests the need to explore additional sources of follow-back to help possibly identify an earlier incidence report. Interstate data exchange following National Death Index linkages may help registries identify and remove erroneous DCO cases from their databases.

OBJECTIVE: To describe the epidemiology of tobacco-associated cancers in Massachusetts from 2006-2015. METHODS: Incident cases of tobacco-associated cancers diagnosed from 2006-2015 were provided by the Massachusetts Cancer Registry. Tobacco-associated cancers include lung, oral cavity, esophageal, laryngeal, pancreatic, cervical, liver, bladder, kidney, stomach, colorectal, and acute myeloid leukemia. Cancer deaths due to those cancers were provided by the Massachusetts Registry for Vital Records and Statistics. Joinpoint regression was used to assess trends in the rates and 95% confidence intervals were used to assess significant differences over the time period. RESULTS: From 2006-2015, 42% of all cancer cases and 60% of all cancer deaths were due to a tobacco-associated cancer. Lung and colorectal cancers had the highest incidence (65.8 and 39.8 per 100,000, respectively) and mortality rates (44.6 and 13.6 per 100,000, respectively) of all the tobacco-associated cancers in Massachusetts. The incidence and mortality rates of lung, esophageal, laryngeal, and colorectal cancer decreased with statistical significance from 2006-2015. Non-Hispanic Whites and non-Hispanic Blacks had the highest incidence (203.9 and 189.2/100,000, respectively) and mortality rates (100.7 and 97.4/100,000, respectively) from tobacco-associated cancers, and these rates have decreased with statistical significance from 2006-2015. CONCLUSION: Tobacco cessation initiatives remain important even as the incidence and mortality rates of some tobacco-associated cancers have decreased in recent years. Understanding the distribution of these cancers by sex and race will provide public health officials with information on populations still affected by these cancers.
RESUMEN
OBJECTIVES: To examine cancer incidence among the 3 Asian, non-Hispanic ethnicities with the highest frequency of cases (South Asian, Chinese, and Vietnamese). METHODS: Age-adjusted incidence rates for all invasive cancers were calculated for South Asian (Indian, Pakistani), Chinese, and Vietnamese cancer cases reported to the Massachusetts Cancer Registry (MCR). Additionally, rates were calculated for the most frequent cancers among non-Hispanic Asians (prostate, colorectal, female breast, female thyroid, lung, and male liver). The 95% confidence intervals were calculated to determine statistical significance between the rates. RESULTS: South Asian and Vietnamese females had significantly elevated rates of all invasive cancers compared to Chinese females, while Chinese and South Asian females had a significantly elevated breast cancer rate. Vietnamese males had a significantly elevated rate of all invasive cancers, liver cancer, and lung cancer compared to the other 2 groups. Due to the high rates of lung cancer among Vietnamese males, MCR current/previous smoking data were compared for all cancers. Among Vietnamese, Chinese, and South Asian male cancer cases, current/ previous smoking percentages were 64%, 51%, and 35%, respectively. CONCLUSIONS: Our analyses showed a significant difference of rates for several cancers by specific Asian ethnicity within the broader Asian, non-Hispanic race category. Differences in tobacco use, maternal hepatitis B infection, and diet likely contribute to some of the differences. These data can aid in the development of prevention programs, such as smoking cessation and mammography screening that are culturally and linguistically specific within this large and diverse group.

IMPORTANCE: Current cancer screening guidelines recommend cessation of cervical cancer screening at the age of 65 years for most women. To examine residual risk among elderly women, we compared cervical cancer incidence rates (IRs) in Massachusetts from 2004 to 2015 among women younger than 65 years versus 65 years and older. MATERIALS AND METHODS: The Massachusetts Cancer Registry was used to identify all women diagnosed with cervical cancer between January 01, 2004, to December 31, 2015. Cancer incidence was calculated based on age of diagnosis (<65 years vs ≥65 years). RESULTS: In Massachusetts, 2,418 incident cases of cervical cancer were diagnosed from 2004 to 2014, of which 571 (23.6%) were diagnosed among women 65 years and older. When compared with women diagnosed younger than 65 years, women diagnosed at the age of 65 years and older were more likely to be diagnosed with stage II or higher (71.8% vs 43.8%, p < .001). Cervical cancer IRs decreased annually for women younger than 65 years from 2004 to 2015. Among women 65 years and older, cancer IRs decreased by 3.9% annually from 2004 to 2013 (p = .0009), but 2013 to 2015 showed an increasing trend (annual percent change + 14.1%, p = .12). CONCLUSIONS AND RELEVANCE: Women 65 years and older account for one quarter of cervical cancer diagnoses in Massachusetts and present with higher-stage disease than younger women. Upcoming planned revisions in screening and prevention guidelines should address the continued risk of cervical cancer for older women.

OBJECTIVE: Describing the burden of cancer in the oldest old (those aged ≥85 years at diagnosis) is important, as the growing elderly population in Massachusetts lives to older ages. METHODS: Incident cases of invasive cancer in Massachusetts from 2004-2014 were provided by the Massachusetts Cancer Registry. The incidence of cancer among the oldest old was compared with the population aged 65-74 years and 75-84 years. Joinpoint regression was used to assess trends in the rates of the most common cancers in the oldest old population. RESULTS: In Massachusetts from 2004-2014, 7.4% of incident cancers in men and 10.2% of incident cancers in women were diagnosed in people aged ≥85 years. The cancer with the highest incidence among the oldest old was lung cancer among men (473.7 cases per 100,000) and breast cancer among women (347.0 cases per 100,000). From 2004-2014, there were statistically significant annual decreases in prostate cancer and colorectal cancer among the oldest old men and women, as well as lung cancer among oldest old men and breast cancer among oldest old women. The oldest old were more likely to be diagnosed at a distant stage of prostate and breast cancer than people diagnosed at ages 65-74 years and ages 75-84 years. CONCLUSIONS: The oldest old population in Massachusetts has a different burden of cancer incidence than the general population, including high incidence and more distant-stage disease. Informing public health departments and practitioners of the common cancers in the population 85 and above is important to improve cancer care in this high comorbidity population.

This brief report describes the burden of cancer among adolescents and young adults (AYAs), aged 15-39 years, in Massachusetts from 2004 to 2014 using data from the Massachusetts Cancer Registry and Registry of Vital Records and Statistics. In Massachusetts, 4.6% of cancer cases and 1.3% of cancer deaths occurred among AYAs. The incidence rate of cancer among AYAs was 77.6 cases per 100,000 and the mortality rate was 8.0 deaths per 100,000. The incidence rates of melanoma and Hodgkin lymphoma have been decreasing annually. The incidence rate of thyroid cancer has been increasing for females aged 15-24 years and males aged 25-39 years.

PURPOSE: To understand trends in the incidence and mortality of two human papillomavirus (HPV)-associated cancers, cervical and oropharyngeal cancer, in Massachusetts. METHODS: From 2004 to 2014, the Massachusetts Cancer Registry recorded 3,996 incident cases of oropharyngeal cancer and 2,193 incident cases of cervical cancer. Mortality data were obtained from the Massachusetts Registry of Vital Records and Statistics from 2008 to 2014. Rates were age-standardized to the 2000 U.S. population and trends were assessed using joinpoint regression. RESULTS: While the incidence rate of cervical cancer (5.46 per 100,000) decreased by 2.41% annually (p = 0.004), the incidence rate of oropharyngeal cancer among males (7.85 per 100,000) increased by 2.82% annually (p = 0.0002). Mortality rates for both cancers decreased from 2008 to 2014 but were not statistically significant (cervical - 3.73% annually, p = 0.29; oropharyngeal - 1.94% annually, p = 0.44). CONCLUSION: The rising incidence rate of oropharyngeal cancer in men and the decreasing, but relatively high, incidence rate of cervical cancer in women highlight the need for further screening and prevention by HPV vaccination in Massachusetts.

PURPOSE: The aim was to provide ethnicity-specific incidence trends of cervical and uterine cancers uncorrected and corrected for the prevalence of hysterectomy in Massachusetts. METHODS: We used incidence data of invasive cervical (International Classification of Diseases for Oncology, Third Edition: C53) and uterine cancer (International Classification of Diseases for Oncology, Third Edition: C54-C55) diagnosed from 1995 to 2010 from the Massachusetts Cancer Registry. Data from the Behavioral Risk Factor Surveillance Survey for Massachusetts were used to model the ethnicity-specific prevalence of hysterectomy. We standardized rates by the US 2000 population standard for the periods 1995 to 1998, 1999 to 2002, 2003 to 2006, and 2007 to 2010. RESULTS: Depending on the period, corrected cervical cancer rates increased by 1.2 to 2.8, 5.6 to 8.3, and 3.2 to 8.2 per 100,000 person-years, and uterine cancer rates increased by 14.3 to 16.7, 14.8 to 29.3, and 6.7 to 15.4 per 100,000 person-years among white non-Hispanic women, black non-Hispanic women, and Hispanic women, respectively. Corrected estimated annual percentage changes increased for uterine cancer among black non-Hispanic women aged 60 years and older. Ethnic disparities between white non-Hispanic women and the other groups became smaller for uterine cancer and larger for cervical cancer after correction. DISCUSSION: Corrections of cervical and uterine cancer rates for hysterectomy prevalence are important as ethnic disparities, age patterns and time trends of cervical and uterine cancer incidence rates change.
