Socioeconomic and racial disparities in the selection of chest wall boost radiation therapy in californian women after mastectomy.

Unlabelled: To better elucidate the socioeconomic and racial differences in women who received postmastectomy radiation therapy with or without a chest wall boost, the records from 4747 women included in the California Cancer Registry were reviewed. Poor and Hispanic women were more likely to receive a chest wall boost than were more affluent and non-Hispanic women.

Introduction: Healthcare disparities in breast cancer treatment have been well documented.

Utilization and impact of a postmastectomy radiation boost for invasive breast cancer.

Purpose: Additional radiation following postmastectomy radiation (PMRT) has an undefined benefit. We investigate those likely to be selected for a chest wall boost (CWB) and its effect on breast cancer survival (BCS) and overall survival (OS).

Methods And Materials: A total of 4747 women diagnosed from 2005 to 2009 were treated with PMRT identified from the California Cancer Registry (CCR); 2686 (57%) received a CWB.

No improvement noted in overall or cause-specific survival for men presenting with metastatic prostate cancer over a 20-year period.

Background: Prostate cancer mortality in the United States has declined by nearly 40% over the last 25 years. However, to the authors' knowledge, the contribution of prostate-specific antigen (PSA) screening for the early detection of prostate cancer remains unclear and controversial. In the current study, the authors attempted to determine whether improvements in survival over time among patients with metastatic prostate cancer have contributed to the decline in mortality.

Cancer incidence trends among native Hawaiians and other Pacific Islanders in the United States, 1990-2008.

Background: Lack of annual population estimates for disaggregated Native Hawaiian and Other Pacific Islander (NHOPI) populations limits the ability to examine cancer incidence rates and trends to understand the cancer burdens among NHOPIs.

Methods: Utilizing 1990 and 2000 population census data, we estimated the annual populations by age and sex for Native Hawaiians, Samoans, and Guamanians/Chamorros for 1990-2008 in regions covered by 13 of the National Cancer Institute's SEER registries. Cancer diagnoses during 1990-2008 from these registries were used to calculate the age-adjusted (2000 US Standard) incidence rates by sex, calendar year/period, and cancer type for each population.

Cancer incidence trends among Asian American populations in the United States, 1990-2008.

Background: National cancer incidence trends are presented for eight Asian American groups: Asian Indians/Pakistanis, Chinese, Filipinos, Japanese, Kampucheans, Koreans, Laotians, and Vietnamese.

Methods: Cancer incidence data from 1990 through 2008 were obtained from 13 Surveillance, Epidemiology, End Results (SEER) registries. Incidence rates from 1990 through 2008 and average percentage change were computed using SEER*Stat and Joinpoint software.

Examining the association between socioeconomic status and invasive colorectal cancer incidence and mortality in California.

Background: Colorectal cancer (CRC) incidence and mortality rates vary across race/ethnicity. Socioeconomic status (SES) also influences CRC rates; however, these associations might be inconsistent across racial/ethnic groups and tumor subsite. We examined associations between area-level SES and CRC incidence and mortality in a population-based registry study of non-Hispanic Whites, African Americans, Hispanics, and Asians/Pacific Islanders from California.

Gastric cancer incidence among Hispanics in California: patterns by time, nativity, and neighborhood characteristics.

Background: Better understanding about gastric cancer incidence patterns among Hispanics by birthplace, socioeconomic status (SES), and acculturation can improve preventive strategies and disease models.

Methods: Incidence rates, rate ratios, and estimated annual percent change (EAPC) in rates of anatomic and histologic subtype-specific gastric cancer were calculated by age, sex, and nativity among Hispanics using California Cancer Registry data from 1988 through 2004. Incidence rates in 1998 to 2002 were compared by neighborhood SES and Hispanic enclave status according to 2000 US Census data.

Racial patterns of extranodal natural killer/T-cell lymphoma, nasal type, in California: a population-based study.

In order to investigate whether the clinical behaviour of extranodal natural killer/T-cell lymphoma, nasal type (ENKTL) varies by race within a geographic region, we identified a total of 213 non-Hispanic whites, Hispanics and Asians/Pacific islanders (APIs) diagnosed with ENKTL in the California Cancer Registry between 2001 and 2008. The incidence and outcomes of the disease in these racial groups were analysed. The incidence rates in non-Hispanic whites, Hispanics and APIs were 0.

Survival following non-small cell lung cancer among Asian/Pacific Islander, Latina, and Non-Hispanic white women who have never smoked.

Background: Lung cancer is the leading cause of cancer death among U.S. Asian/Pacific Islander (API) and Latina women despite low smoking prevalence.

Lifetime risks of specific breast cancer subtypes among women in four racial/ethnic groups.

Introduction: Breast cancer comprises clinically distinct subtypes, but most risk statistics consider breast cancer only as a single entity. To estimate subtype-specific lifetime breast cancer risks, we took advantage of population-based data for which information regarding tumor expression of estrogen receptor (ER), progesterone receptor (PR) and HER2/neu (HER2) was newly available.

Methods: We included women whose breast cancer was diagnosed in the state of California from 2006 to 2007 and was reported to the National Cancer Institute's Surveillance, Epidemiology and End Results Program (N = 40,936).

Breast cancer incidence patterns among California Hispanic women: differences by nativity and residence in an enclave.

Background: Breast cancer incidence is higher in U.S.-born Hispanic women than foreign-born Hispanics, but no studies have examined how these rates have changed over time.
