BackgroundPancreatic cancer is the fourth-leading cause of cancer deaths in the United States. The silent nature of the disease and its poor prognosis, the need for further research, along with the need to assess the outcomes of current approaches necessitate an ongoing evaluation of the epidemiology and mortality-trends of this malignancy. Continuous monitoring of disease-patterns, on population-levels, may help scientists assess the quality of healthcare delivery, boost their understanding of diseases' characteristics and risk factors, and detect gaps whereby further research is needed. None of the previous reports shed light on pancreatic adenocarcinomas (PAC), the most common type of Pancreatic Cancer, as the primary outcome. In this study we aim to investigate PAC’s incidence and mortality trends over the last four decades in the United States.MethodsWe used SEER 9 database to study PAC cases during 1974-2014. Incidence and mortality rates were calculated by sex, age, race, state and stage of PAC. Annual percent change (APC) was calculated using joinpoint regression software.ResultsWe reviewed 67,878 PAC cases; most of these cases were in the head of pancreas. Overall PAC incidence rates increased 1.03% (95% CI, 0.86-1.21, p <.001) per year over the study period. Rates of adenocarcinoma of the head of pancreas increased 0.87% (95% CI, 0.68-1.07, p <.001), and rates of adenocarcinoma of the body and tail of pancreas increased 3.42% (95% CI, 3.06-3.79, p <.001) per year during 1973-2014. PAC incidence-based mortality increased 2.22% (95% CI, 1.93-2.51, p <.001) per year. However, during 2012-2014 there was a statistically significant decrease in PAC incidence-based mortality; APC, -24.70% (95% CI, -31.78 - -16.88, p <.001).ConclusionPAC’s incidence and mortality rates have been increasing for decades. However, the last few years have shown a promising decrease in mortality. We believe that further advances in healthcare delivery and research can lead to a further mortality decrease. Future studies can use this paper as a baseline to keep monitoring the outcomes of PAC's therapy.Electronic supplementary materialThe online version of this article (10.1186/s12885-018-4610-4) contains supplementary material, which is available to authorized users.

: Colorectal cancer (CRC) is the third most common cancer and the second leading cause of cancer related death in the world with an estimated number of 1.8 million new cases and about 881,000 deaths worldwide in 2018. The epide-miology of CRC varies significantly between different regions in the world as well as between different age, gender and racial groups. Multiple factors are involved in this variation including risk factor exposure, demographic variations in addi-tion to genetic susceptibility and genetic mutations and their effect on the prognosis and treatment response. In this mini review, we are discussing the recent epidemiological trend including the incidence and mortality of colorectal cancer world-wide and the factors affecting these trends.

Background: Renal cell carcinoma (RCC) is one of the common malignancies in the United States. RCC incidence and mortality have been changing due to many reasons. We provide a thorough investigation of incidence and mortality trends of RCC in the US using the surveillance, epidemiology and end results (SEER) database. Methods: The SEER 13 registries were accessed for RCC cases diagnosed between 1992 and 2015. Incidence and mortality were calculated by demographic and tumor characteristics. We calculated annual percent changes (APC) of these rates. Rates were expressed by 100,000 personyears. Results: A total of 104,584 RCC cases were reviewed with 47,561 deaths. The overall incidence was 11.281 per 100,000 person-years. Incidence increased by 2.421% per year (95% CI, 2.096-2.747, p<.001) but later became stable since 2008. However, the incidence of clear-cell subtype continued to increase (1.449%; 95% CI, 0.216-2.697, P=.024). RCC overall mortality rates have been declining since 2001. However, mortality associated with distant RCC only started to decrease in 2012 with APC of −18.270% (−28.775-6.215, P = .006)

Background The focus on noncancer causes of death in patients with breast cancer (BC) remains superficial. The objective of the current study was to assess and quantify causes of death after BC diagnosis. Methods In total, 754,270 women with BC in the United States who were diagnosed during 2000 through 2015 and retrieved from the Surveillance, Epidemiology, and End Results (SEER) program were studied. Standardized mortality ratios (SMRs) for causes of death were calculated. Results Of the included patients, 183,002 (24.3%) died during the follow‐up period. The greatest proportion of deaths (46.2%) occurred within 1 to 5 years after diagnosis. Most deaths occurred from BC itself or from other cancers, and the number of BC deaths decreased as more years passed after diagnosis. The most common noncancer causes of death within <10 years after diagnosis were heart diseases followed by cerebrovascular diseases. However, >10 years after diagnosis, the most common noncancer causes of death were heart diseases followed by Alzheimer disease. Patients had a statistically significant higher risk of death from chronic liver diseases within 5 to 10 years after diagnosis compared with the general population (SMR, 1.23; 95% CI, 1.09‐1.38) and had statistically significant higher risks of death from Alzheimer disease (SMR, 1.21; 95% CI, 1.14‐1.29) and from diseases of the heart (SMR, 1.06; 95% CI, 1.02‐1.09) >10 years after diagnosis. Conclusions Although BC remains the most common cause of death after BC diagnosis, other non‐BC causes of death (mainly heart and cerebrovascular diseases) represent a significant number of deaths among patients with BC. These findings provide important insight into how BC survivors should be counselled regarding future health risks.

BACKGROUND:The suicide risk after a new cancer diagnosis remains a controversial issue. This study examines the suicide risk within the year after a cancer diagnosis. This is the largest study to assess recent trends in suicide risk after a cancer diagnosis. METHODS: Data were obtained from the Surveillance, Epidemiology, and End Results Program. All patients diagnosed with cancer between 2000 and 2014 were selected. The event was defined as death due to suicide within the first year after a cancer diagnosis, and patients who experienced the event after their diagnosis were observed. The observed/expected (O/E) ratio was assessed as well as the excess risk per 10,000 person-years to determine the suicide risk change after the diagnosis in comparison with the general population. RESULTS: A total of 4,671,989 patients with cancer were included; 1585 committed suicide within 1 year of their diagnosis. The risk of suicide increased significantly with an O/E ratio of 2.52 and with an excess risk of 2.51 per 10,000 person-years. When the risk of suicide was studied according to the cancer site, the highest increases in the O/E ratio came after diagnoses of pancreatic cancer (8.01) and lung cancer (6.05). The risk of suicide also increased significantly after a diagnosis of colorectal cancer with an O/E ratio of 2.08. However, the risk of suicidal death did not increase significantly after breast and prostate cancer diagnoses. CONCLUSIONS: The risk of suicide increases significantly in the first year after a diagnosis of cancer in comparison with the general population, and this increase varies with the type and prognosis of cancer. Close observation and referral to mental health services, when indicated, are important for mitigating such risk. Cancer 2019;125:972-979.
