An assessment of survival outcomes among ovarian cancer patients at the National and Referral Hospital in Kenya.

BACKGROUND: Ovarian cancer has been shown to have poor survival outcomes attributed to late presentation. In Kenya, information on the survival outcomes of ovarian cancer patients is scarce. Therefore, the objective of this study was to examine the survival outcomes among patients with ovarian cancer treated at Kenyatta National Hospital (KNH). AIMS: A hospital-based retrospective cohort study was performed at KNH to examine the survival outcomes of 112 ovarian cancer patients. The study employed a structured data abstraction tool to acquire patients' relevant socio-demographic and clinical characteristics from the patient's medical records. The data obtained were analyzed using SPSS version 29.0 statistical software. Kaplan-Meier and Cox regression analyses were used to determine the survival outcome and predictors of mortality among ovarian cancer patients, respectively. METHODS AND RESULTS: The mean age of the patients in this study was 51.28 ± 14.24 years. Most patients (59.8%) had evidence of distant metastasis during the follow-up period. One-third (33%) of patients were deceased. The mean-cancer-specific survival time among the study participants was 40.0 ± 3.0 months. The 5-year survival rate was 44%, with most patients experiencing disease progression during the last follow-up. Combination therapy (p < .001) was the only statistically significant predictor of mortality in ovarian cancer patients. CONCLUSION: The study found that the 5-year survival rate among ovarian cancer patients was poor, with most patients experiencing disease progression during the last follow-up period.

Survival outcomes of rare cutaneous malignancies within an insured cohort of patients, 1988-2018.

BACKGROUND: There are limited survival data on cutaneous angiosarcoma (CAS), dermatofibrosarcoma protuberans (DFSP), Merkel cell carcinoma (MCC), and sebaceous carcinoma (SC). OBJECTIVE: To analyze survival trends in CAS, DFSP, MCC, and SC among a racially diverse, insured cohort of patients. METHODS: Using data from the Kaiser Permanente Southern California Cancer Registry, we identified adults diagnosed with CAS, DFSP, MCC, or SC between January 1, 1988 and December 31 2018, followed through December 31, 2021. RESULTS: Our cohort consisted of 83 diagnoses of CAS, 490 diagnoses of DFSP, 411 diagnoses of MCC, and 249 diagnoses of SC. Our analysis revealed no significant differences in overall or disease-specific 1000 person-years mortality rates among our populations of non-Hispanic Whites, Hispanics, African American/Blacks, and Asian American/Pacific Islanders diagnosed with CAS, DFSP, MCC, or SC. On multivariate analysis, controlling for patient and tumor characteristics, there was similarly no increased risk of overall mortality for minorities diagnosed with CAS, DFSP, MCC, or SC. LIMITATIONS: Retrospective nature of the analysis and small sample size. CONCLUSION: Contrary to existing literature, our results show a notable lack of racially driven survival disparities among insured individuals with CAS, DFSP, MCC, and SC, emphasizing the importance of health care coverage.

Overall Survival in Patients With Multiple Myeloma in the U.S.: A Systematic Literature Review of Racial Disparities.

Multiple myeloma (MM) accounts for 10% of hematologic cancers in the U.S.; however, incidence and mortality occur disproportionately between racial groups in real-world settings. Our study's objective was to systematically characterize the disparities in overall survival (OS) among Black and White patients with MM in the US using real-world evidence studies. A systematic literature review was undertaken by searching Embase and MEDLINE for observational studies conducted in the US, published between January 1, 2015 and October 25, 2021, and reporting OS for Black and White patients with MM. Records were reviewed by 2 independent researchers. OS data were extracted as hazard ratios (HR), median survival, or %, with methods of adjustment, as reported. Evidence quality was assessed by data source, population, and variables for which HRs for risk of death were adjusted. We included 33 US studies comprising 410,086 patients (21.5% Black; 78.5% White) with MM. Receipt of treatment varied; however, most studies reported that patients either underwent stem cell transplant and/or received systemic therapy. HRs from 9 studies were considered "high quality" by comparing nationally representative, generalizable cohorts and adjusting for key prognostic, treatment, and/or socioeconomic factors. After adjustment, these data suggested that Black patients exhibit similar or superior survival outcomes compared with their White counterparts. When data are adjusted for important confounders, Black patients exhibit better or equal survival to White patients, indicating that similarities in patient populations and equal access to treatment can bridge the disparity in patient outcomes between races.

Impact of social disparities on 10 year survival rates in paediatric cancers: a cohort study.

Background: Studies reporting on the impact of social determinants of health on childhood cancer are limited. The current study aimed to examine the relationship between health disparities, as measured by the social deprivation index, and mortality in paediatric oncology patients using a population-based national database. Methods: In this cohort study of children across all paediatric cancers, survival rates were determined using the Surveillance, Epidemiology, and End Results (SEER) database from 1975 to 2016. The social deprivation index was used to measure and assess healthcare disparities and specifically the impact on both overall and cancer-specific survival. Hazard ratios were used to assess the association of area deprivation. Findings: The study cohort was composed of 99,542 patients with paediatric cancer. Patients had a median age of 10 years old (IQR: 3-16) with 46,109 (46.3%) of female sex. Based on race, 79,984 (80.4%) of patients were identified as white while 10,801 (10.9%) were identified as Black. Patients from socially deprived areas had significantly higher hazard of death overall for both non-metastatic [1.27 (95% CI: 1.19-1.36)] and metastatic presentations [1.09 (95% CI: 1.05-1.15)] compared to in more socially affluent areas. Interpretation: Patients from the most socially deprived areas had lower rates of overall and cancer-specific survival compared to patients from socially affluent areas. With an increase in childhood cancer survivors, implementation of social determinant indices, such as the social deprivation index, might aid improvement in healthcare outcomes for the most vulnerable patients. Funding: There was no study sponsor or extramural funding.

Assessment of survival outcomes among lung cancer patients at the National and Referral Hospital in Kenya.

INTRODUCTION: Lung cancer has a low overall survival rate linked to late diagnosis and metastasis. Unfortunately, comprehensive data within the African continent are limited due to the lack of a registry, low public awareness of lung cancer, financial constraints, and inadequate screening and treatment facilities. In addition, there was a lack of conclusive data in our setting. Therefore, this study aimed to assess survival outcomes among lung cancer patients at Kenyatta National Hospital. METHODS: A hospital-based retrospective cohort study was performed to examine the survival outcomes of 151 lung cancer patients. All eligible lung cancer patients diagnosed and treated in the facility between January 1, 2018, and December 31, 2020, were included. The patients were retrospectively followed from the date of primary cancer diagnosis until death or the last follow-up period. The Statistical Package for the Social Sciences (SPSS) version 20.0 statistical software was used to enter and analyze the data. Kaplan-Meier survival and Cox regression analysis were employed to determine median survival and predictors of mortality, respectively. RESULTS: The mean and median follow-time was 18.2 and 17.5 months, respectively. Most (98%) of the patients had non-small cell lung cancer. The 2-year survival rate was 66.7%, with 59.6% of patients having developed distant metastasis during the follow-up, while 25.1% were deceased. The median cancer-specific survival time among the study population was 18.0 ± 3.40 months. Cox regression analyses showed that patients with distant metastasis had five times more risk of dying (AHR: 4.74, 95% CI: 2.1-10.8, p < 0.001) than patients without distant metastasis. CONCLUSIONS: The overall two-year survival rate of lung cancer patients at the Kenyatta National Hospital was 66.7%, with most patients developed distant metastasis during the follow-up period. Distant metastasis was the only significant predictor of mortality among lung cancer patients in our setting.

Survival, cost and added therapeutic benefit of drugs granted early access through the French temporary authorization for use program in solid tumors from 2009 to 2019.

Decisions on market authorization (MA) and reimbursement have different durations across countries because of health technology assessment (HTA) procedures and negotiations between manufacturers and national authorities. To overcome this delay, France has implemented a Temporary Authorization for Use (ATU) program that allows early access to drugs before MA, in order to treat patients with unmet medical needs. The objectives of our study were to establish the added therapeutic benefit (ATB) of ATUs for solid tumors and to investigate the correlations between three tools evaluating ATB and survival outcomes and drug costs. Data on ATUs granted from January 2009 to December 2019 to treat solid tumors were analyzed. An assessment of their ATB was conducted using the American Society of Clinical Oncology-Value Framework (ASCO-VF), the European Society for Medical Oncology-Magnitude Clinical Benefit Scale (ESMO-MCBS) and the French HTA criterion, clinical added value (CAV). The latter score determines reimbursement and national market access. Thirty-five drugs in 39 indications were granted ATUs. All of them obtained MA and derived a clinical benefit to be reimbursed by the Social Security. Twenty-eight (71.8%) had CAV compared to preexisting therapies. 24/38 (63.2%) had a 4-5 ESMO-MCBS score and 19/33 (57.6%) had an ASCO-VF score over 45. No correlations were found between cost, PFS, OS, CAV and ASCO-VF score, while high ESMO-MCBS scores were correlated to OS. In conclusion, many patients were treated with innovations before MA thanks to ATU, although there are discrepancies between ATB scales, hence the importance of international collaboration in the evaluation of innovative therapies.

National Utilization, Survival, and Costs Analysis of Treatment Options for Stage I Non-Small Cell Lung Cancer: A SEER-Medicare Database Analysis.

RATIONALE AND OBJECTIVES: To compare utilization, outcomes, and costs of surgery, radiation therapy, and percutaneous ablation for the treatment of stage I non-small cell lung cancer (NSCLC). MATERIALS AND METHODS: Using 2006-2016 Medicare-linked Surveillance, Epidemiology, and End Results (SEER) databases, stage I NSCLC patients who underwent surgery, radiotherapy, or percutaneous ablation were identified using relevant billing codes. National utilization rates were determined. Overall survival for treatment arms were compared using log-rank test and Cox-proportional hazard modeling. Mean direct costs for each treatment strategy during the first year after diagnosis were compared using Analysis of Variance. RESULTS: A total of 15,847 Stage I NSCLC patients were identified; mean age at diagnosis was 75.5 years (minimum age = 66 years) and 59.2% were female. A total of 10,732 patients (67.7%) underwent only surgery, 5013 (31.6%) only radiotherapy, and 102 (0.6%) only ablation. Utilization of surgery and ablation decreased while radiotherapy utilization increased from 2007 to 2015 (p < 0.0001). Compared to the ablation group, overall survival was greater for the surgery group (HR: 0.7, 95% CI of HR: 0.6-0.9, p = 0.0047) and lower for the radiotherapy group (HR: 1.4, 95% CI of HR: 1.1-1.8, p = 0.002). The mean first year cost of therapy for ablation = $11,976) was significantly less (p < 0.05) than for radiotherapy ($15,447) and surgery ($22,669). CONCLUSION: In Medicare patients with stage I NSCLC, the utilization of radiation therapy has increased and surgery has declined, while utilization of percutaneous ablation has remained uniformly low. Although overall survival is best for surgery, then ablation, and then radiation therapy, first year treatment costs are lowest for ablation.

Patient characteristics, treatment patterns, and mortality in elderly patients newly diagnosed with acute myeloid leukemia meeting ineligibility criteria for high intensity chemotherapy.

To describe patient characteristics, treatment patterns, and survival among elderly patients (≥66 years) newly diagnosed with acute myeloid leukemia (AML) meeting ≥1 ineligibility criteria for high-intensity chemotherapy (HIC; i.e. age >75 years, cardiac disease/prior anthracycline therapy, or secondary AML), we analyzed 2007-2017 100% Medicare hematologic cancer data. Patients were stratified based on whether they received HIC or low-intensity chemotherapy (LIC) or best supportive care (BSC) within 60 days after AML diagnosis. Of 4,152 patients, 43.2% received chemotherapy, 33.8% BSC, and 23.1% no therapy. Among chemotherapy-treated patients, HIC was more common than LIC (58.8 vs 41.2%), despite targeting patients meeting ≥1 ineligibility criteria for HIC. Poor overall survival was observed for patients receiving chemotherapy and BSC (median overall survival [interquartile range]: HIC, 1.9 [0.8, 6.6] months; LIC, 3.8 [1.4, 9.3] months; BSC, 1.0 [0.4, 2.5] months). Results highlight the need for additional effective and tolerable treatments for this population.

Validation and comparison of Breast Graded Prognostic Assessment scores in patients with breast cancer and brain metastases.

PURPOSE: Brain metastases (BM) occur in 15-35% of patients with metastatic breast cancer, conferring poor prognosis and impairing quality of life. Clinical scores have been developed to classify patients according to their prognosis. We aimed to check the utility of the Breast Graded Prognostic Assessment (B-GPA) and its modified version (mB-GPA) and compare them in routine clinical practice. METHODS: This is an ambispective study including all patients with breast cancer BM treated in a single cancer comprehensive center. We analyzed the overall survival (OS) from BM diagnosis until death. The Kaplan-Meier method and Cox proportional hazard regression model were used in the analyses. ROC curves were performed to compare both scores. RESULTS: We included 169 patients; median age was 50 years. HER2-positive and triple negative patients were 33.7% and 20.7%, respectively. At the last follow-up, 90% of the patients had died. Median OS was 12 months (95% confidence interval 8.0-16.0 months). OS was worse in patients with > 3 BM and in patients with triple negative subtype. CONCLUSIONS: In our series, we confirm that B-GPA and mB-GPA scores correlated with prognosis. ROC curves showed that B-GPA and mB-GPA have similar prognostic capabilities, slightly in favor of mB-GPA.

Gastric Cancer Disparities Among Asian American Subpopulations.

BACKGROUND/AIM: Asian Americans (AA) are one of the largest and fastest growing minority groups in the United States consisting of 18 million people. This population is an ethnically diverse group that tends to be classified as one cohort resulting in hidden survival disparities among AA subgroups. PATIENTS AND METHODS: The National Cancer Data Base was queried for patients of Korean, Japanese or Filipino ancestry with gastric adenocarcinoma or esophageal adenocarcinoma between 2004 and 2013. RESULTS: A total of 28,213 patients met the inclusion criteria: 1,542 with gastric adenocarcinoma and 26,671 with esophageal adenocarcinoma. The Korean group with gastric cancer (0.42) showed improved 5-year survival over the Japanese (0.31) and Filipino (0.21; p<0.001) groups. CONCLUSION: A significant difference in survival exists among AA subgroups signifying a need to acknowledge the heterogeneity of AA in future studies. Thus, individual-specific medicine with respect to race-related outcomes is extremely important.

Association Between Primary Payer Status and Survival in Patients With Stage III Colon Cancer: An National Cancer Database Analysis.

BACKGROUND: Colon cancer is the third most frequent cancer diagnosis, and primary payer status has been shown to be associated with treatment modalities and survival in cancer patients. The goal of our study was to determine the between-insurance differences in survival in patients with clinical stage III colon cancer using data from the National Cancer Database (NCDB). MATERIALS AND METHODS: We identified 130,998 patients with clinical stage III colon cancer in the NCDB diagnosed from 2004 to 2012. Kaplan-Meier curves and multivariable Cox regression models were used to determine the association between insurance status and survival. RESULTS: Patients with private insurance plans were 28%, 30%, and 16% less likely to die than were uninsured patients, Medicaid recipients, and Medicare beneficiaries, respectively. Medicare patients were 14% were less likely to die compared with uninsured patients. Patients receiving chemotherapy were, on average, 65% less likely to die compared with the patients not receiving chemotherapy. CONCLUSION: Private insurance and a greater socioeconomic status were associated with increased patient survival compared with other insurance plans or the lack of insurance. Future research should continue to unravel how socioeconomic status and insurance status contribute to the quality of care and survival of oncologic patients.

Population analysis of socioeconomic status and otolaryngologist distribution on head and neck cancer outcomes.

BACKGROUND: The relationship between clinical outcomes and geographic determinants is not well known for head and neck cancer. Socioeconomic status (SES) factors and the distribution of health care resources might impact outcomes. METHODS: Head and neck cancer cases in the Surveillance, Epidemiology, and End Results (SEER) database were studied. Patient-level prognostic factors were identified from the SEER, and county-level factors were identified from the Area Health Resource File. Stage at presentation and observed survival were the outcomes of interest, with predictive factors identified by multivariate logistic and Cox proportional hazards regression. RESULTS: On multivariate analysis, tumor site, sex, race, marital status, rural residence, and county poverty level predicted stage at presentation. Sex, race, marital status, county-level poverty, and number of otolaryngologists predicted observed survival. CONCLUSION: Adverse county-level SES predicted advanced cancer stage at presentation and diminished observed survival. SES was a stronger predictor of patient outcomes than rurality or number of otolaryngologists.

Preoperative nutritional status assessment predicts postoperative outcomes in patients with surgically resected non-small cell lung cancer.

BACKGROUND: As nutritional status plays an important role in outcomes after surgery, this study evaluated the association between preoperative nutritional status (NS) and postoperative outcomes after major resection for lung cancer. METHODS: We identified 219 patients with a diagnosis of cancer who underwent pulmonary resection from 2010 to 2012. Preoperative NS was assessed by anthropometric and biological parameters, body mass index (BMI), and the Nutritional Risk Index (NRI). We stratified this population into 4 BMI groups: underweight, normal weight, overweight and obese and 4 NRI groups: well-nourished; mildly malnourished; moderately malnourished and severely malnourished. The outcomes measured were postoperative complications; 30-day postoperative mortality; hospital length of stay (LOS), overall survival (OS) and disease-free survival (DFS). We performed both unadjusted analysis and adjusted multivariable analysis, controlling for statistically significant variables. RESULTS: Mean BMI and NRI were, respectively, 26.5 ± 4.3 and 112.4 ± 3.3. There were no significant differences between BMI categories and resection type, pathological stage, or overall postoperative complications. By contrast, significant differences (p < 0.05) in postoperative complications were observed among the NRI groups. LOS was longer in underweight and/or malnourished patients. In terms of OS, we found no significant differences according to NRI and BMI; however, patients with underweight had significantly shorter DFS compared with patients with overweight and obesity (log-rank p-value = 0.001). CONCLUSION: NS as measured by the NRI is an independent predictor of the risk of postsurgical complications, regardless of clinicopathologic characteristics. NRI might therefore be an useful tool for identifying early-stage lung cancer patients at risk for postoperative complications.

Impact of socioeconomic status on survival for patients with anal cancer.

BACKGROUND: Although outcomes for patients with squamous cell carcinoma of the anus (SCCA) have improved, the gains in benefit may not be shared uniformly among patients of disparate socioeconomic status. In the current study, the authors investigated whether area-based median household income (MHI) is predictive of survival among patients with SCCA. METHODS: Patients diagnosed with SCCA from 2004 through 2013 in the Surveillance, Epidemiology, and End Results registry were included. Socioeconomic status was defined by census-tract MHI level and divided into quintiles. Multivariable Cox proportional hazards models and logistic regression were used to study predictors of survival and radiotherapy receipt. RESULTS: A total of 9550 cases of SCCA were included. The median age of the patients was 58 years, 63% were female, 85% were white, and 38% were married. In multivariable analyses, patients living in areas with lower MHI were found to have worse overall survival and cancer-specific survival (CSS) compared with those in the highest income areas. Mortality hazard ratios for lowest to highest income were 1.32 (95% confidence interval [95% CI], 1.18-1.49), 1.31 (95% CI, 1.16-1.48), 1.19 (95% CI, 1.06-1.34), and 1.16 (95% CI, 1.03-1.30). The hazard ratios for CSS similarly ranged from 1.34 to 1.22 for lowest to highest income. Older age, black race, male sex, unmarried marital status, an earlier year of diagnosis, higher tumor grade, and later American Joint Committee on Cancer stage of disease also were associated with worse CSS. Income was not found to be associated with the odds of initiating radiotherapy in multivariable analysis (odds ratio of 0.87 for lowest to highest income level; 95% CI, 0.63-1.20). CONCLUSIONS: MHI appears to independently predict CSS and overall survival in patients with SCCA. Black race was found to remain a predictor of SCCA survival despite controlling for income. Further study is needed to understand the mechanisms by which socioeconomic inequalities affect cancer care and outcomes. Cancer 2018;124:1791-7. © 2018 American Cancer Society.

Real-World Economic Burden Associated with Transplantation-Related Complications.

Approximately 20,000 hematopoietic cell transplantation (HCT) procedures are performed annually in the United States. Real-world data on the costs associated with post-transplantation complications are limited. Patients with hematologic malignancies aged ≥18 years undergoing autologous HCT (auto-HCT) or allogeneic HCT (allo-HCT) between January 1, 2011, and June 30, 2014, were identified in the Truven Health MarketScan Research Databases. Patients were required to have 12 months of continuous medical and pharmacy enrollment before and after HCT; patients who experience inpatient death within 12 months post-HCT were also included. Patients with previous HCT were excluded. Potential HCT-related complications were identified if they had a medical claim with a diagnosis code for relapse; infection; cardiovascular, renal, neurologic, pulmonary, hepatic, or gastrointestinal disease; secondary malignancy; thrombotic microangiopathy; or posterior reversible encephalopathy syndrome within 1 year post-HCT. Healthcare costs attributable to these complications were evaluated by comparing total costs in HCT recipients with complications and those without complications. The MarketScan Research Databases were further linked to the Social Security Administration's Master Death File to obtain patient death events in a subset of patients. A total of 2672 HCT recipients were included in the analysis. The mean ± SD age of recipients was 54.5 ± 11.6 years, and the majority of recipients (63.6%) underwent auto-HCT. Complications were identified in 81% of auto-HCT recipients and in 95.5% of allo-HCT recipients. Most complications occurred within 180 days post-HCT. Compared with Auto-HCT recipients without complications, those with complications incurred $51,475 higher adjusted total costs (P < .01). Compared with allo-HCT recipients without complications, those with complications incurred $181,473 higher adjusted total costs (P < .01). Among the patients with mortality data, auto-HCT recipients with complications had a higher mortality rate (13.4% vs 5.7%, P < .01) and a lower probability of survival (P < .01) compared with those without complications. In allo-HCT recipients, however, the mortality rate and probability of survival were not significantly different between those with complications and those without complications. HCT recipients with complications were associated with considerable economic burden in terms of direct healthcare costs in a commercially insured population, and in the case of auto-HCT, a higher mortality rate was observed in those with complications.

Distance from a Comprehensive Cancer Center: A proxy for poor cervical cancer outcomes?

OBJECTIVE: To evaluate the potential relationship between outcomes in cervical cancer patients based on distance from our Comprehensive Cancer Center (CCC). METHODS: A retrospective cohort study of cervical cancer patients was performed. Abstracted data included: demographics, clinicopathologic variables, treatment, and survival. Analyses both by quartiles and distance <100 and ≥100miles from our institution were performed. Data were analyzed using SAS version 9.2. RESULTS: 390 patients living a median distance of 58.1miles (range 1.2-571miles) from our CCC were identified. Patients were generally white (n=249), non-smokers (n=226), with Stage IB disease (n=222), squamous histology (n=295) and underwent primary surgical therapy (n=229). Patients were divided into both quartiles as well as two strata: <100 and ≥100miles for comparison. Progression-free survival (PFS) and overall survival (OS) favored patients living closer to our center with a lower median OS for patients living ≥100miles (65.4vs. 99.4months; p=0.040). Cox proportional hazard modeling noted that advanced stage was predictive of inferior PFS and OS, while other clinical covariates including age, BMI, race, smoking status and histology had a variable impact on outcomes and distance >100miles was associated with a higher risk of death (hazard ratio [HR]=1.68, 95% confidence interval [CI] 1.11-2.54). CONCLUSION: Overall survival for patients living >100miles from our CCC was worse when compared to patients in closer proximity. Outreach efforts and utilization of navigators may help decrease the impact of geographic and racial disparities on outcomes.

Survival outcomes scores (SOFT, BAR, and Pedi-SOFT) are accurate in predicting post-liver transplant survival in adolescents.

SOFT and BAR scores utilize recipient, donor, and graft factors to predict the 3-month survival after LT in adults (≥18 years). Recently, Pedi-SOFT score was developed to predict 3-month survival after LT in young children (≤12 years). These scoring systems have not been studied in adolescent patients (13-17 years). We evaluated the accuracy of these scoring systems in predicting the 3-month post-LT survival in adolescents through a retrospective analysis of data from UNOS of patients aged 13-17 years who received LT between 03/01/2002 and 12/31/2012. Recipients of combined organ transplants, donation after cardiac death, or living donor graft were excluded. A total of 711 adolescent LT recipients were included with a mean age of 15.2±1.4 years. A total of 100 patients died post-LT including 33 within 3 months. SOFT, BAR, and Pedi-SOFT scores were all found to be good predictors of 3-month post-transplant survival outcome with areas under the ROC curve of 0.81, 0.80, and 0.81, respectively. All three scores provided good accuracy for predicting 3-month survival post-LT in adolescents and may help clinical decision making to optimize survival rate and organ utilization.

Survival differences of Asian and Caucasian epithelial ovarian cancer patients in the United States.

OBJECTIVE: To compare the racial differences in treatment and survival of Asian-Americans and White patients with epithelial ovarian cancer. METHODS: Data were obtained from the Surveillance, Epidemiology, and End Results Program between 1988 and 2009 and analyzed using Chi-squared tests, Kaplan-Meier methods, and Cox regression analysis. RESULTS: Of the 52,260 women, 3932 (7.5%) were coded as Asian, and 48,328 (92.5%) were White. The median age of Asians at diagnosis was 56 vs. 64 years for the Whites (p<0.001). Asians were more likely to undergo primary surgery, have an earlier stage of disease, have a diagnosis of a non-serous histology, and have lower grade tumors. The 5-year disease-specific survival (DSS) of Asians was higher compared to Whites (59.1% vs. 47.3%, p<0.001). On a subset analysis, Vietnamese, Filipino, Chinese, Korean, Japanese, and Asian Indian/Pakistani ethnicities had 5-year DSS of 62.1%, 61.5%, 61.0%, 59.0%, 54.6%, and 48.2%, respectively (p=0.015). On multivariate analysis, age at diagnosis, year of diagnosis, race, surgery, stage, and tumor grade were all independent prognostic factors for survival. Asians were further stratified to U.S. born versus those who were born in Asia and immigrated. Asian immigrants presented at a younger age compared to U.S. born Asians. Immigrants were found to have an improved 5-year DSS when compared to U.S. born Asians and Whites of 55%, 52%, and 48%, respectively (p<0.001). CONCLUSION: Asians were more likely to be younger, undergo primary surgery, have an earlier stage of disease, non-serous histology, lower grade tumors, and higher survival.

Cost effectiveness of first-line pemetrexed plus platinum compared with other regimens in the treatment of patients with nonsquamous non-small cell lung cancer in the US outpatient setting.

This retrospective observational study evaluated cost effectiveness of first-line treatment of advanced nonsquamous non-small cell lung cancer (NSCLC) with pemetrexed/platinum (Pem/Plat) relative to paclitaxel/carboplatin (Pac/Carbo) and paclitaxel/carboplatin/bevacizumab (Pac/Carbo/Bev). Patients initiating first-line treatment from 2006 to 2009 were identified in electronic medical records of 20 US oncology practices. Pem/Plat patients were matched 1:1 on important characteristics with Pac/Carbo and Pac/Carbo/Bev patients and followed for 1 year to assess progression, survival, and costs. Bootstrapping was used to calculate the probability of falling within quadrants of the incremental cost-effectiveness plane. Kaplan-Meier analysis and Cox proportional hazards regression modeling were also performed. Three hundred Pem/Plat patients (mean age, 67.6 years; male, 56.0%; PS 0/1, 71.0%) were matched with 300 patients in the other cohorts. Median PFS was 134 days (Pem/Plat) versus 106 days (Pac/Carbo) (hazard ratio [HR]: 0.67, P < 0.001) and 126 days (Pac/Carbo/Bev) (HR: 0.68, P < 0.001). Median OS was 298 days (Pem/Plat) versus 218 days (Pac/Carbo) (HR: 0.88, P = 0.08) and 271 days (Pac/Carbo/Bev) (HR: 0.93, P = 0.31). Pem/Plat therapy costs were higher versus Pac/Carbo ($21,841 higher PFS; $19,137 higher OS; P ≤ 0.05) and lower versus Pac/Carbo/Bev ($15,160 lower PFS; $19,946 lower OS; P ≤ 0.05). Pem/Plat had a greater probability of higher costs/higher effectiveness versus Pac/Carbo (PFS, 90.1%; OS, 96.3%) and lower costs/higher effectiveness versus Pac/Carbo/Bev (PFS, 69.5%; OS, 85.0%). Pem/Plat had higher cost and effectiveness than Pac/Carbo; depending on a payer's or society's willingness to pay, Pem/Plat may be considered cost effective compared with Pac/Carbo. Pem/Plat yielded greater effectiveness with lower costs than Pac/Carbo/Bev.
