Cancer Mortality Risk

This introductory overview describes the recommencement of the Cancer Mortality Risks project, a systematic medical-actuarial comparative analysis of selected cancer mortality risks originally initiated by the authors in the year 2002 utilizing the National Cancer Institute (NCI) SEER*Stat 4.2.3 (Surveillance, Epidemiology, and End Results) database between 1973 and 2002 and released April 3, 2002. This study is based on approximately 40 major invasive cancer anatomic sites used in previous conversions of the National Cancer Institute SEER survival data to comparative mortality in the Medical Risks monographs published in 19761 and 1990.2 Anatomic site-specific cancer mortality abstracts of SEER survival data containing 20-year comparative mortality follow-up by cohort entry-period, histologic type, age, sex, race, stage, grade and other variables was proposed for publication as a monograph, compendium or a series of concise but detailed mortality articles.

Cancer Mortality Risk

Abstract Background/Purpose Psychological distress can influence cancer mortality through socioeconomic disadvantage, health-risk behaviors, or reduced access to care. These disadvantages can result in higher risks of cancer occurrence, a delayed cancer diagnosis, hamper adherence to treatment, and provoke inflammatory responses leading to cancer. Previous studies have linked psychological distress to cancer mortality. However, studies are lacking for the U.S. population. Methods This study examines the Kessler six-item psychological distress scale as a risk factor for U.S. cancer mortality using the pooled 1997–2014 data from the National Health Interview Survey (NHIS) linked to National Death Index (NDI) (N = 513,012). Cox proportional hazards regression was used to model survival time as a function of psychological distress and sociodemographic and behavioral covariates. Results In Cox models with 18 years of mortality follow-up, the cancer mortality risk was 80% higher (hazard ratio [HR] = 1.80; 95% CI = 1.64, 1.97) controlling for age; 61% higher (HR = 1.61; 95% CI = 1.46, 1.76) in the SES-adjusted model, and 33% higher (HR = 1.33; 95% CI = 1.21, 1.46) in the fully-adjusted model among adults with serious psychological distress (SPD), compared with adults without psychological distress. Males, non-Hispanic Whites, and adults with incomes at or above 400% of the federal poverty level had greater cancer mortality risk associated with SPD. Using an 8 years of mortality follow-up, those with SPD had 108% increased adjusted risks of mortality from breast cancer. Conclusion Our study findings underscore the significance of addressing psychological well-being in the population as a strategy for reducing cancer mortality.

Cranial Metastasis

Object Resection and whole-brain radiation therapy (WBRT) have classically been the standard treatment for a single metastasis to the brain. The objective of this study was to evaluate the use of Gamma Knife surgery (GKS) as an alternative to WBRT in patients who had undergone resection and to evaluate patient survival and local tumor control. Methods The authors retrospectively reviewed the charts of 150 patients treated with a combination of stereotactic radiosurgery and resection of a cranial metastasis at their institution between April 1997 and September 2009. Patients who had multiple lesions or underwent both WBRT and GKS were excluded, as were patients for whom survival data beyond the initial treatment were not available. Clinical and imaging follow-up was assessed using notes from clinic visits and MR imaging studies when available. Follow-up data beyond the initial treatment and survival data were available for 68 patients. Results The study included 37 women (54.4%) and 31 men (45.6%) (mean age 60 years, range 28–89 years). In 45 patients (66.2%) there was systemic control of the primary tumor when the cranial metastasis was identified. The median duration between resection and radiosurgery was 15.5 days. The median volume of the treated cavity was 10.35 cm3 (range 0.9–45.4 cm3), and the median dose to the cavity margin was 15 Gy (range 14–30 Gy), delivered to the 50% isodose line (range 50%–76% isodose line). The patients' median preradiosurgery Karnofsky Performance Scale (KPS) score was 90 (range 40–100). During the follow-up period we identified 27 patients (39.7%) with recurrent tumor located either local or distant to the site of treatment. The median time from primary treatment of metastasis to recurrence was 10.6 months. The patients' median length of survival (interval between first treatment of cerebral metastasis and last follow-up) was 13.2 months. For the patient who died during follow-up, the median time from diagnosis of cerebral metastasis to death was 11.5 months. The median duration of survival from diagnosis of the primary cancer to last follow-up was 30.2 months. Patients with a pretreatment KPS score ≥ 90 had a median survival time of 23.2 months, and patients with a pretreatment KPS score < 90 had a median survival time of 10 months (p < 0.008). Systemic control of disease at the time of metastasis was not predictive of increased survival duration, although it did tend to improve survival. Conclusions Although the debate about the ideal form of radiation treatment after resection continues, these findings indicate that GKS combined with surgery offers comparable survival duration and local tumor control to WBRT for patients with a diagnosis of a single metastasis.

Abstract Background Cancer patients’ prognoses are complicated by comorbidities. Prognostic prediction models with inappropriate comorbidity adjustments yield biased survival estimates. However, an appropriate claims-based comorbidity risk assessment method remains unclear. This study aimed to compare methods used to capture comorbidities from claims data and predict non-cancer mortality risks among cancer patients. Methods Data were obtained from the National Health Insurance Service-National Sample Cohort database in Korea; 2979 cancer patients diagnosed in 2006 were considered. Claims-based Charlson Comorbidity Index was evaluated according to the various assessment methods: different periods in washout window, lookback, and claim types. The prevalence of comorbidities and associated non-cancer mortality risks were compared. The Cox proportional hazards models considering left-truncation were used to estimate the non-cancer mortality risks. Results The prevalence of peptic ulcer, the most common comorbidity, ranged from 1.5 to 31.0%, and the proportion of patients with ≥1 comorbidity ranged from 4.5 to 58.4%, depending on the assessment methods. Outpatient claims captured 96.9% of patients with chronic obstructive pulmonary disease; however, they captured only 65.2% of patients with myocardial infarction. The different assessment methods affected non-cancer mortality risks; for example, the hazard ratios for patients with moderate comorbidity (CCI 3–4) varied from 1.0 (95% CI: 0.6–1.6) to 5.0 (95% CI: 2.7–9.3). Inpatient claims resulted in relatively higher estimates reflective of disease severity. Conclusions The prevalence of comorbidities and associated non-cancer mortality risks varied considerably by the assessment methods. Researchers should understand the complexity of comorbidity assessments in claims-based risk assessment and select an optimal approach.

AbstractWe examined the mortality risks among 2463 individuals who were exposed in utero to atomic bomb radiation in Hiroshima or Nagasaki in August 1945 and were followed from October 1950 through 2012. Individual estimates of mother’s weighted absorbed uterine dose (DS02R1) were used. Poisson regression method was used to estimate the radiation-associated excess relative risk per Gy (ERR/Gy) and 95% confidence intervals (CI) for cause-specific mortality. Head size, birth weight, and parents’ survival status were evaluated as potential mediators of radiation effect. There were 339 deaths (216 males and 123 females) including deaths from solid cancer (n = 137), lymphohematopoietic cancer (n = 8), noncancer disease (n = 134), external cause (n = 56), and unknown cause (n = 4). Among males, the unadjusted ERR/Gy (95% CI) was increased for noncancer disease mortality (1.22, 0.10–3.14), but not for solid cancer mortality (− 0.18, < − 0.77–0.95); the unadjusted ERR/Gy for external cause mortality was not statistically significant (0.28, < − 0.60–2.36). Among females, the unadjusted ERRs/Gy were increased for solid cancer (2.24, 0.44–5.58), noncancer (2.86, 0.56–7.64), and external cause mortality (2.57, 0.20–9.19). The ERRs/Gy adjusted for potential mediators did not change appreciably for solid cancer mortality, but decreased notably for noncancer mortality (0.39, < − 0.43–1.91 for males; 1.48, − 0.046–4.55 for females) and external cause mortality (0.10, < − 0.57–1.96 for males; 1.38, < − 0.46–5.95 for females). In conclusion, antenatal radiation exposure is a consistent risk factor for increased solid cancer mortality among females, but not among males. The effect of exposure to atomic bomb radiation on noncancer disease and external cause mortality among individuals exposed in utero was mediated through small head size, low birth weight, and parental loss.

Prostate cancer treatment strategies are guided by risk-stratification. This stratification can be difficult in some patients with known comorbidities. New models are needed to guide strategies and determine which patients are at risk of prostate cancer mortality. This article presents a gradient-boosting model to predict the risk of prostate cancer mortality within 10 years after a cancer diagnosis, and to provide an interpretable prediction. This work uses prospective data from the PLCO Cancer Screening and selected patients who were diagnosed with prostate cancer. During follow-up, 8776 patients were diagnosed with prostate cancer. The dataset was randomly split into a training (n = 7021) and testing (n = 1755) dataset. Accuracy was 0.98 (±0.01), and the area under the receiver operating characteristic was 0.80 (±0.04). This model can be used to support informed decision-making in prostate cancer treatment. AI interpretability provides a novel understanding of the predictions to the users.

Introduction: Uterine sarcoma accounts for nearly 3% of all uterine malignancies. They have 4 major pathology includes endometrial stromal sarcoma high grade, ESS low grade, uterine leiomyosarcoma (uLMS) and undifferentiated uterine sarcoma (UUS). Recent WHO classification 2014, recognizes low grade ESS and high grade ESS as distinct entity. They differ from endometrial carcinoma in their aggressive nature and poor prognosis. We review our database and found total 44 eligible patient treated at our institute. Materials and Methods: Its retrospective analysis of computer based database of our institute from January 2009 to December 2015. We analyzed demographic, pathological, treatment and survival data. Results: Total 44 patient treated for uterine sarcoma at our institute. Among these 16 were operated at our institute during study period. Here we reporting results of operated patients at our institute. The histological diagnosis LMS (5/16), ESS-L (4/16), MMMT (3/16), UUS (3/16) and ESS-H (1/16). Stage distribution was stage I, (6/16) stage II, (5/16) stage III, (3/16) stage IV, (0/16) and unknown stage (2/16). Two patients underwent completion surgery for outside myomectomy. The adjuvant treatment was CT in 3/16, CT with RT in 7/16, HT in 4/16 and one lost to follow up with one was put on observation. Median follow up is 30 month with 14 patients alive and one lost to follow up. At last follow up 4 patients alive with metastatic disease and 10 patients alive with no evidence of disease. Conclusion: Uterine sarcoma are uncommon disease with
