Long-Term Survivors of Pancreatic Cancer: A California Population-Based Study.
Ontology highlight
ABSTRACT: Objectives
Pancreatic cancer continues to carry a poor prognosis with survival rates that have had minimal improvement over the past 4 decades. We report a population-based, comprehensive analysis of long-term survivors of pancreatic adenocarcinoma diagnosed in the diverse population of California.Methods
Data from the California Cancer Registry were used to evaluate long-term survival. A total of 70,442 patients diagnosed with pancreatic adenocarcinoma between 1988 and 2009 were identified. Logistic regression was used to identify factors associated with achieving 5-year survival.Results
The overall 5-year survival was 2.5%, with minimal incremental improvements throughout the 3 decades. Age, stage, degree of differentiation, and surgical resection were associated with 5-year survival. Furthermore, younger age and receiving care at a National Cancer Institute-designated cancer center were similarly correlated with 5-year survival regardless of surgical intervention. In addition, we identified stage, differentiation, and adjuvant chemotherapy as significant factors for long-term survival in surgically resected patients. In the unresectable patients, Asian/Pacific islanders and Hispanics were significantly more likely to reach the 5-year milestone than non-Hispanic whites.Conclusions
Although pancreatic cancer mortality remains high, our study highlights baseline characteristics, treatment, biological factors, and ethnicity that are associated with long-term survival. These findings may serve as a springboard for further investigation.

Project description:ObjectiveThe majority of endometrial cancer patients are overweight or obese at cancer diagnosis. Obesity is a shared risk factor for both endometrial cancer and diabetes, but it is unknown whether endometrial cancer patients have increased diabetes risks. The aim of our study was to investigate diabetes risk among endometrial cancer patients.MethodsEndometrial cancer patients diagnosed between 1997 and 2012 in Utah (n = 2,314) were identified. Women from the general population (n = 8,583) were matched to the cancer patients on birth year and birth state. Diabetes diagnoses were identified from electronic medical records and statewide healthcare facility databases. Cox proportional hazards models were used to estimate hazard ratios for diabetes after cancer diagnosis.ResultsEndometrial cancer survivors had a significantly higher risk of type II diabetes when compared to women from the general population in the first year after cancer diagnosis (HR = 5.22, 95% CI = 4.05, 6.71), >1-5 years after cancer diagnosis (HR = 1.67, 95% CI = 1.31, 2.12), and >5 years after cancer diagnosis (HR = 1.65, 95% CI = 1.29, 2.11). Endometrial cancer patients who were obese at cancer diagnosis had a three-fold increase in type II diabetes risk (HR = 2.99, 95%CI = 2.59, 3.45). Although endometrial cancer patients diagnosed at distant stage had a higher risk of diabetes, cancer treatment did not appear to contribute to any diabetes risks.ConclusionsIn conclusion, endometrial cancer survivors had a higher risk of diabetes than women in the general population. These results suggest that long term monitoring for diabetes is indicated for endometrial cancer survivors.

Project description:PURPOSE:For older women with breast cancer, local therapy options may include lumpectomy plus whole-breast irradiation (Lump + WBI), lumpectomy plus brachytherapy (Lump + Brachy), lumpectomy alone (Lump alone), mastectomy without radiation therapy (Mast alone), and mastectomy plus radiation therapy (Mast + RT). We surveyed a population-based cohort of older breast cancer survivors to assess the association of local therapy with long-term quality-of-life outcomes. METHODS AND MATERIALS:We used nationally comprehensive Medicare claims to identify women aged ?67 years in whom nonmetastatic breast cancer was diagnosed in 2009, who were treated with 1 of the 5 aforementioned treatment options, and who were still alive in 2015. From this cohort, 1650 patients (330 patients per treatment) were randomly selected. A survey that included the CanSORT (Cancer Surveillance and Outcomes Research Team) Satisfaction with Breast Cosmetic Outcome, BREAST-Q, Decisional Regret Scale, and EQ-5D-3L was mailed to potential participants. We used multivariable linear regression to assess associations between local therapy and outcomes after adjusting for patient, disease, and treatment covariates. RESULTS:Among the 489 women who returned the surveys (30% response rate), the median age at diagnosis was 72 years (range, 67-87 years). The interval from diagnosis to survey completion was approximately 6 years for all patients. Compared with Lump + WBI (adjusted score, 3.40), the CanSORT cosmetic satisfaction scores were higher for Lump + Brachy (score, 3.77; P = .007) and Lump alone (score, 3.80; P = .04) and lower for Mast + RT (score, 3.01; P = .006). Similar trends were seen for BREAST-Q cosmetic satisfaction. BREAST-Q psychosocial, sexual, and physical well-being and EQ-5D-3L global health status tended to be better in patients treated with less irradiation and less surgery. BREAST-Q adverse radiation effects were worse for Lump + WBI compared with Lump + Brachy. Decisional regret regarding surgery and radiation therapy did not differ across groups. Compared with patients treated with Lump + WBI, patients treated with Lump + Brachy and Lump alone reported slightly higher rates of in-breast recurrence (excess risk of 5.8% and 6.4%, respectively; P = .01). CONCLUSIONS:In this nationally diverse cohort, less irradiation and less surgery were associated with better long-term quality-of-life outcomes. However, patient regret regarding surgery and radiation therapy was similar across all groups.

Project description:BACKGROUND:Evidence suggests that physical activity (PA) is beneficial for reducing fatigue in colorectal cancer (CRC) survivors. However, little is known regarding long-term effects of PA on fatigue and whether pre-diagnosis PA is associated with less fatigue in the years after diagnosis. Our study aimed to investigate the association of pre- and post-diagnosis PA with long-term fatigue in CRC survivors. METHODS:This study used a German population-based cohort of 1781 individuals, diagnosed with CRC in 2003-2014, and alive at five-year follow-up (5YFU). Physical activity was assessed at diagnosis and at 5YFU. Fatigue was assessed by the Fatigue Assessment Questionnaire and the EORTC Quality of Life Questionnaire-Core 30 fatigue subscale at 5YFU. Multivariable linear regression was used to explore associations between pre- and post-diagnosis PA and fatigue at 5YFU. RESULTS:No evidence was found that pre-diagnosis PA was associated with less fatigue in long-term CRC survivors. Pre-diagnosis work-related PA and vigorous PA were even associated with higher levels of physical (Beta (ß)?=?2.52, 95% confidence interval (CI)?=?1.14-3.90; ß?=?2.03, CI?=?0.65-3.41), cognitive (ß?=?0.17, CI?=?0.05-0.28; ß?=?0.13, CI?=?0.01-0.25), and affective fatigue (ß?=?0.26, CI?=?0.07-0.46; ß?=?0.21, CI?=?0.02-0.40). In cross-sectional analyses, post-diagnosis PA was strongly associated with lower fatigue on all scales. CONCLUSIONS:In this study, pre-diagnosis PA does not appear to be associated with less fatigue among long-term CRC survivors. Our results support the importance of ongoing PA in long-term CRC survivors. Our findings might be used as a basis for further research on specific PA interventions to improve the long-term outcome of CRC survivors.

Project description:Background:Endometrial cancer is the second most common cancer among female cancer survivors in the United States. Cardiovascular disease is the leading cause of death among endometrial cancer survivors. Studies that examine long-term cardiovascular outcomes among endometrial cancer survivors are critical. Methods:Cohorts of 2648 endometrial cancer survivors diagnosed between 1997 and 2012 and 10 503 age-matched women from the general population were identified. Cardiovascular disease diagnoses were identified from electronic medical records and statewide ambulatory surgery and statewide inpatient data. Cox regression models were used to estimate hazard ratios (HRs) at one to five years, more than five to 10 years, and more than 10 years after cancer diagnosis. Results:Between one and five years after diagnosis, increased cardiovascular risks among endometrial cancer survivors were observed for phlebitis, thrombophlebitis, and thromboembolism (HR = 2.07, 99% confidence interval [CI] = 1.57 to 2.72), pulmonary heart disease (HR = 1.74, 99% CI = 1.26 to 2.40), and atrial fibrillation (HR = 1.50, 99% CI = 1.07 to 2.11). At more than five to 10 years, some elevated risk persisted for cardiovascular diseases. Compared with patients who had surgery, patients who additionally had radiation therapy and/or chemotherapy were at increased risk for heart and circulatory system disorders between one and five years after cancer diagnosis. Older age and obesity were also risk factors for hypertension and heart disease among endometrial cancer survivors. Conclusions:Endometrial cancer survivors are at higher risk for various adverse long-term cardiovascular outcomes compared with women from the general population. This study suggests that increased monitoring for cardiovascular diseases may be necessary for endometrial cancer patients for 10 years after cancer diagnosis.

Project description:BackgroundIncreasing evidence of cure for some neoplasms has emerged in recent years. The study aimed to estimate population-based indicators of cancer cure.MethodsInformation on more than half a million cancer patients aged 15-74 years collected by population-based Italian cancer registries and mixture cure models were used to estimate the life expectancy of fatal tumors (LEFT), proportions of patients with similar death rates of the general population (cure fraction), and time to reach 5-year conditional relative survival (CRS) >90% or 95% (time to cure).ResultsBetween 1990 and 2000, the median LEFT increased >1 year for breast (from 8.1 to 9.4 years) and prostate cancers (from 5.2 to 7.4 years). Median LEFT in 1990 was >5 years for testicular cancers (5.8) and Hodgkin lymphoma (6.3) below 45 years of age. In both sexes, it was ≤0.5 years for pancreatic cancers and NHL in 1990 and in 2000. The cure fraction showed a 10% increase between 1990 and 2000. It was 95% for thyroid cancer in women, 94% for testis, 75% for prostate, 67% for breast cancers, and <20% for liver, lung, and pancreatic cancers. Time to 5-year CRS >95% was <10 years for testis, thyroid, colon cancers, and melanoma. For breast and prostate cancers, the 5-year CRS >90% was reached in <10 years but a small excess remained for >15 years.ConclusionsThe study findings confirmed that several cancer types are curable. Became aware of the possibility of cancer cure has relevant clinical and social impacts.

Project description:OBJECTIVE:With the increasing incidence of endometrial cancer, the high survival rate, and the large number of endometrial cancer survivors, investigations of long-term genitourinary outcomes are important for the management of these outcomes among endometrial cancer survivors. METHODS:Cohorts of 2648 endometrial cancer survivors diagnosed in the state of Utah between 1997 and 2012 and 10,503 general population women were identified. All ICD-9 diagnosis codes were collected from the state's two largest healthcare systems and statewide databases. Multivariate Cox regression models were used to estimate hazard ratios at 1-5years and >5-10years after endometrial cancer diagnosis for genitourinary outcomes. RESULTS:Endometrial cancer survivors were at elevated risk for urinary system disorders between 1 and 5years (HR: 1.64, 95% CI: 1.50-1.78) and >5-10years (HR: 1.40, 95% CI: 1.26-1.56) and genital organ disorders between 1 and 5years (HR: 1.71, 95% CI: 1.58-2.03) and >5-10years (HR: 1.33, 95% CI: 1.19-1.49). Significantly elevated risk was observed among endometrial cancer survivors for renal failure, chronic kidney disease, urinary tract infections, and nonmalignant breast conditions, persisting between >5-10years. Between 1 and 5years after cancer diagnosis, those with higher stage, higher grade, older age and treated with radiation or chemotherapy were at higher risk for urinary disorders. CONCLUSIONS:Endometrial cancer survivors were at higher risk for many genitourinary outcomes compared to women from the general population. This study presents evidence suggesting the necessity of increased monitoring and counseling for genitourinary disorders for endometrial cancer patients both immediately after treatment cessation and for years afterwards.

Project description:BackgroundWe surveyed the occurrence of physical symptoms among long-term gynaecological cancer survivors after pelvic radiation therapy, and compared with population-based control women.MethodsWe identified a cohort of 789 eligible gynaecological cancer survivors treated with pelvic radiation therapy alone or combined with surgery in Stockholm or Gothenburg, Sweden. A control group of 478 women was randomly sampled from the Swedish Population Registry. Data were collected through a study-specific validated postal questionnaire with 351 questions concerning gastrointestinal and urinary tract function, lymph oedema, pelvic bones and sexuality. Clinical characteristics and treatment details were retrieved from medical records.ResultsParticipation rate was 78% for gynaecological cancer survivors and 72% for control women. Median follow-up time after treatment was 74 months. Cancer survivors reported a higher occurrence of symptoms from all organs studied. The highest age-adjusted relative risk (RR) was found for emptying of all stools into clothing without forewarning (RR 12.7), defaecation urgency (RR 5.7), difficulty feeling the need to empty the bladder (RR 2.8), protracted genital pain (RR 5.0), pubic pain when walking indoors (RR 4.9) and erysipelas on abdomen or legs at least once during the past 6 months (RR 3.6). Survivors treated with radiation therapy alone showed in general higher rates of symptoms.ConclusionGynaecological cancer survivors previously treated with pelvic radiation report a higher occurrence of symptoms from the urinary and gastrointestinal tract as well as lymph oedema, sexual dysfunction and pelvic pain compared with non-irradiated control women. Health-care providers need to actively ask patients about specific symptoms in order to provide proper diagnostic investigations and management.

Project description:PurposeLimited research suggests that cancer survivors have problems with insurance. Our study aimed to gain insight into the proportion of very long-term (14-24 years post-diagnosis) survivors of breast, colorectal, and prostate cancers who had problems with health (HI) and life (LI) insurance.MethodsWe used data from CAESAR (CAncEr Survivorship-A multi-Regional population-based study). Participants completed questions on change in insurance providers since cancer diagnosis, problems with requesting (additional) HI or LI, and how potential problems were resolved. We conducted logistic regression to determine factors associated with change in statutory HI.ResultsOf the 2714 respondents, 174 (6%) reported having changed HI providers. Most switched between different statutory HI providers (86%), 9% from statutory to private, and 5% from private to statutory. Respondents who changed statutory HI providers were more likely to be prostate cancer survivors (OR 2.79, 95% CI 1.01-7.68) while being ≥ 65 years at time of diagnosis (OR 0.58, 95% CI 0.35-0.96) and having ≥ 2 comorbid conditions (OR 0.61, 95% CI 0.40-0.92) were associated with reduced odds for change. Problems in changing HI were minimal and were resolved with additional contribution. Of the 310 respondents who tried to get LI, 25 respondents reported having difficulties, of whom the majority had their request rejected.ConclusionMost cancer survivors did not change their HI nor tried to buy LI after cancer diagnosis. Problems with changing statutory HI were generally resolved with additional contribution while the main problem encountered when buying LI was rejection of request.

Project description:Pancreatic ductal adenocarcinoma is a lethal cancer with fewer than 7% of patients surviving past 5 years. T-cell immunity has been linked to the exceptional outcome of the few long-term survivors, yet the relevant antigens remain unknown. Here we use genetic, immunohistochemical and transcriptional immunoprofiling, computational biophysics, and functional assays to identify T-cell antigens in long-term survivors of pancreatic cancer. Using whole-exome sequencing and in silico neoantigen prediction, we found that tumours with both the highest neoantigen number and the most abundant CD8+ T-cell infiltrates, but neither alone, stratified patients with the longest survival. Investigating the specific neoantigen qualities promoting T-cell activation in long-term survivors, we discovered that these individuals were enriched in neoantigen qualities defined by a fitness model, and neoantigens in the tumour antigen MUC16 (also known as CA125). A neoantigen quality fitness model conferring greater immunogenicity to neoantigens with differential presentation and homology to infectious disease-derived peptides identified long-term survivors in two independent datasets, whereas a neoantigen quantity model ascribing greater immunogenicity to increasing neoantigen number alone did not. We detected intratumoural and lasting circulating T-cell reactivity to both high-quality and MUC16 neoantigens in long-term survivors of pancreatic cancer, including clones with specificity to both high-quality neoantigens and predicted cross-reactive microbial epitopes, consistent with neoantigen molecular mimicry. Notably, we observed selective loss of high-quality and MUC16 neoantigenic clones on metastatic progression, suggesting neoantigen immunoediting. Our results identify neoantigens with unique qualities as T-cell targets in pancreatic ductal adenocarcinoma. More broadly, we identify neoantigen quality as a biomarker for immunogenic tumours that may guide the application of immunotherapies.

Project description:BackgroundTestis cancer (TC) patients are young with excellent cancer prognosis. Hence, the risk of late-onset treatment-related morbidity and mortality is of concern due to longer survival after treatment.ObjectiveWe set to characterize long-term survival of TC patients through a Canadian population dataset.Design setting and participantsWe used a population-based dataset, the Canadian Census Health and Environment Cohort (CanCHEC), to identify individuals diagnosed with TC between 1991 and 2010. We compared them with all other male individuals without TC.Outcome measurements and statistical analysisThe primary outcome was mortality due to cardiovascular disease (CVD) or nontesticular malignancy. Mann-Whitney or chi-square test was used where applicable. Data were analyzed using a Cox proportional hazard model with and without matching.Results and limitationsWe identified 1950 individuals with TC. We compared them with 1 300 295 men with no TC. There were 335 deaths in the study group during the study period (17.2%) with a mean follow-up of 19.6 yr. TC patients were at increased risk of death from secondary malignancies (hazard ratio [HR] 1.63, 95% confidence interval [CI] 1.39-1.91; p < 0.0001) with specific risks for hematologic neoplasms (HR 3.86, 95% CI 2.78-5.37; p < 0.001) and other malignancies (HR 2.41, 95% CI 1.76-3.29; p < 0.001). Gastrointestinal, hematologic, and respiratory toxicities were the most common secondary malignancies leading to death. When stratified according to histology, nonseminoma (NS) patients were at significantly increased risk of death from CVD (HR 2.03, 95% CI 1.27-3.25; p = 0.0032). Individuals with seminoma were at increased risk of death from other nontestis neoplasms (HR 1.46, 95% CI 1.17-1.82; p = 0.0007), specifically hematologic neoplasms (HR 2.09, 95% CI 1.18-3.72; p = 0.0118).ConclusionsNS patients are at increased risk of CVD-related death, whereas seminoma patients are at increased risk of death from non-testis-related malignancies.Patient summaryWe report long-term mortality following diagnosis of testis cancer. Nonseminoma patients have an increased risk of death from cardiovascular disease, while seminoma patients have an increased risk of death from secondary malignancies.
