Breast cancer survivors are at an increased risk of second primary cancers, and the risk factors for the latter may have clinical significance. The aims of our study were to evaluate the incidences and risk factors of second primary female genital cancers (corpus uteri, cervix uteri plus ovary) in a large cohort of breast cancer survivors. Using the Surveillance, Epidemiology, and End Results (SEER) database, we examined the standardized incidence ratio (SIR) and risk factors for second primary female genital cancers observed between 2000 and 2014...

We present a Monte Carlo simulation model that reproduces US invasive breast cancer incidence and mortality trends from 1975 to 2010 as a function of screening and adjuvant treatment. This model was developed for multiple purposes, including to quantify the impact of screening and adjuvant therapy on past and current trends, predict future trends, and evaluate potential outcomes under hypothetical screening and treatment interventions. The model first generates the life histories of individual breast cancer patients by determining the patient's age, tumor size, estrogen receptor (ER) status, human epidermal growth factor 2 (HER2) status, SEER (Surveillance, Epidemiology, and End Results) historic stage, detection mode at time of detection, preclinical tumor course, and death age and cause of death (breast cancer v...

The University of Wisconsin Breast Cancer Epidemiology Simulation Model (UWBCS), also referred to as Model W, is a discrete-event microsimulation model that uses a systems engineering approach to replicate breast cancer epidemiology in the US over time. This population-based model simulates the lifetimes of individual women through 4 main model components: breast cancer natural history, detection, treatment, and mortality. A key feature of the UWBCS is that, in addition to specifying a population distribution in tumor growth rates, the model allows for heterogeneity in tumor behavior, with some tumors having limited malignant potential (i...

BACKGROUND: As molecular subtyping of breast cancer influences clinical management, the evaluation of screening and adjuvant treatment interventions at the population level needs to account for molecular subtyping. Performing such analyses are challenging because molecular subtype-specific, long-term outcomes are not readily accessible; these markers were not historically recorded in tumor registries. We present a modeling approach to estimate historical survival outcomes by estrogen receptor (ER) and human epidermal growth factor receptor 2 (HER2) status...

PURPOSE: The surgery with adjuvant radiation for the treatment of thymoma is still debated. The aim of this study was to examine the efficacy of postoperative radiotherapy (PORT) in a population-based registry of patients with thymoma. MATERIALS AND METHODS: We conducted a retrospective analysis of the Surveillance, Epidemiology, and End Results database to compare the outcomes of patients with thymoma who received surgery with or without PORT. RESULTS: Among the 2234 patients of this study, the surgery with PORT group had a longer mean overall survival [OS] and cancer-specific survival [CSS] than did the surgery without PORT group (OS: 172...

Background: Thymoma, though a rare tumor disease, is the most common tumor of the anterior mediastinum. However, tumor size, as a critical factor, has been underestimated. Results: Age, advanced tumor stage, and preoperative radiotherapy were poor prognostic factors of overall survival (OS) and disease specific survival (DSS) ( P < 0.05 for all). Besides, tumor size was significantly related to survival. The larger tumor size indicated the less OS and DSS ( P < 0...

OBJECTIVE: Marital status has been found as an independent prognostic factor for survival in colorectal cancer (CRC). However, it is unclear whether patients with different marital status have benefited the same from the treatment improvement. METHODS: We queried the Surveillance, Epidemiology, and End Results (SEER) 9 database for patients diagnosed with CRC from 1975 to 2009. Yearly survival data was presented with overlying loess smoothing lines, stratifying by marital status...

BACKGROUND: Current staging paradigms from the American Joint Committee on Cancer (AJCC) staging system for upper urinary tract carcinomas treat locoregionally advanced (T4 and N+) and metastatic (M1) patients as a single entity (stage IV). The current study proposes a modification of the AJCC staging system where these 2 entities are separated. METHODS: The Surveillance, Epidemiology, and End Results (SEER) database (2004-2014) was accessed through SEER*Stat program...

To investigate the interrelation between economic, marital, and known histopathologic/therapeutic prognostic factors in presentation and survival of patients with lung cancer in nine different ethnic groups. A retrospective review of the SEER database was conducted through the years 2007-2012. Population differences were assessed via chi-square testing. Multivariable analyses (MVA) were used to detect overall survival (OS) differences in the total population (TP, N = 153,027) and for those patients presenting with Stage IV (N = 70,968)...

Mountain of studies has showed that right-sided colon cancer (RSCC) and left-sided colon cancer (LSCC) have different clinical presentation and biologic features and should be considered as two distinct disease entities. The survival difference between RSCC and LSCC remains controversial. Using Surveillance, Epidemiology, and End Results (SEER) database, we identified colon adenocarcinoma patients from 2004 to 2013. The 5-year cause-specific survival (CSS) was our primary endpoint. All statistical analyses were performed using the Intercooled Stata 13...

BACKGROUND: The U.S. military health system (MHS) provides universal health care access to its beneficiaries. However, whether the universal access has translated into improved patient outcome is unknown. This study compared survival of non-small cell lung cancer (NSCLC) patients in the MHS with that in the U.S. general population. METHODS: The MHS data were obtained from The Department of Defense's (DoD) Automated Central Tumor Registry (ACTUR) and the U.S. population data were drawn from the National Cancer Institute's Surveillance, Epidemiology, and End Results (SEER) program...

BACKGROUND: Reported rates of the incidence of lymph node metastasis in soft tissue sarcoma vary considerably. Many are based on single-institution series and small patient populations. Certain sarcoma subtypes, including synovial sarcoma, have been associated with a higher risk of lymph node involvement. Most single centers have insufficient numbers of patients to assess lymph node metastasis accurately, but larger national databases may allow a more accurate estimation. QUESTIONS/PURPOSES: We queried a large national database and asked the following questions: (1) What proportion of patients with soft tissue sarcoma have lymph node metastasis and distant metastasis? (2) What histologic subtypes are associated with increased risk of nodal metastasis? (3) What is the impact of lymph node metastases and histologic subtype on survival? (4) Does lymph node excision improve survival of patients with soft tissue sarcoma? METHODS: The National Cancer Institute's Surveillance, Epidemiology, and End Results (SEER) Program is a national database that covers a geographic cross-section representing approximately 28% of the US population across demographic groups...

Purpose Little is known about the extent to which genetic counseling is integrated into community practices for patients newly diagnosed with breast cancer. We examined the receipt of clinically indicated genetic counseling in these patients. Patients and Methods We surveyed 5,080 patients between the ages of 20 and 79 years, diagnosed from July 2013 to August 2015 with early-stage breast cancer and reported to the SEER registries of Georgia and Los Angeles County. Surveys were linked to SEER clinical data and genetic test results...

PURPOSE: Most melanoma studies have been performed in the white population who exhibits the highest incidence rate due to their skin sensitivity to UV radiation. Previous publications have shown that young women (approximately under the menopausal age) exhibit higher incidence rates than men of the same age, and the causes are mostly attributed to their sun behavior or indoor tanning. In our recent publications, we suggested that higher risk in younger women was due to pathophysiological factors, such as hormonal impact, and thus this higher risk in young women should be shared across ethnicities regardless of their skin color or UV behavior...

As diagnostic and therapeutic modalities for Hodgkin's Lymphoma (HL) continue to improve, patient-related factors affecting survival become more difficult to identify. Very little is known about the relationship between the primary site of lymph node (LN) involvement and survival of HL patients. We retrospectively analyzed the United States Surveillance, Epidemiology and End Results (SEER) database for 12,658 HL patients reported between 1973 and 2010 using survival analysis and time-interval multiple logistic regression (MLR) to disclose that relationship...
