Background. Non-Hodgkin lymphoma (NHL) incidence rates have increased considerably in New Zealand.Methods. Incidence and mortality rates for NHL from 1981 to 2010 were calculated. Trends in age-specific rates were analysed and age-period-cohort models fitted to explore generation-specific changes in incidence and mortality.Results. NHL incidence increased by 67% for men and 74% for women between the 1981–1985 and 2006–2010 time periods in New Zealand. For women born about 1936 and men born about 1946, NHL incidence and mortality have diverged suggesting an improved prognosis for recent generations.Conclusion. The strong generation effects suggest that an exposure before 25 years of age is of major importance in determining the lifetime risk of NHL in New Zealand. NHL incidence rates in New Zealand will continue to increase in the future and probably more in females than males, as generations with increased risk age. Current hypotheses for the cause of NHL do not explain the trends observed. A decline in the prevalence of a protective factor may have also contributed to these trends. Examination of trends for subtypes of NHL and innovative testable hypotheses that may explain these trends are needed.

BACKGROUND Cancer poses a serious threat to the health of Chinese people, resulting in a major challenge for public health work. Today, people can obtain relevant information from not only medical workers in hospitals, but also the internet in any place in real-time. Search behaviors can reflect a population’s awareness of cancer from a completely new perspective, which could be driven by the underlying cancer epidemiology. However, such Web-retrieved data are not yet well validated or understood. OBJECTIVE This study aimed to explore whether a correlation exists between the incidence and mortality of cancers and normalized internet search volumes on the big data platform, Baidu. We also assessed whether the distribution of people who searched for specific types of cancer differed by gender. Finally, we determined whether there were regional disparities among people who searched the Web for cancer-related information. METHODS Standard Boolean operators were used to choose search terms for each type of cancer. Spearman’s correlation analysis was used to explore correlations among monthly search index values for each cancer type and their monthly incidence and mortality rates. We conducted cointegration analysis between search index data and incidence rates to examine whether a stable equilibrium existed between them. We also conducted cointegration analysis between search index data and mortality data. RESULTS The monthly Baidu index was significantly correlated with cancer incidence rates for 26 of 28 cancers in China (lung cancer: r=.80, P<.001; liver cancer: r=.28, P=.016; stomach cancer: r=.50, P<.001; esophageal cancer: r=.50, P<.001; colorectal cancer: r=.81, P<.001; pancreatic cancer: r=.86, P<.001; breast cancer: r=.56, P<.001; brain and nervous system cancer: r=.63, P<.001; leukemia: r=.75, P<.001; Non-Hodgkin lymphoma: r=.88, P<.001; Hodgkin lymphoma: r=.91, P<.001; cervical cancer: r=.64, P<.001; prostate cancer: r=.67, P<.001; bladder cancer: r=.62, P<.001; gallbladder and biliary tract cancer: r=.88, P<.001; lip and oral cavity cancer: r=.88, P<.001; ovarian cancer: r=.58, P<.001; larynx cancer: r=.82, P<.001; kidney cancer: r=.73, P<.001; squamous cell carcinoma: r=.94, P<.001; multiple myeloma: r=.84, P<.001; thyroid cancer: r=.77, P<.001; malignant skin melanoma: r=.55, P<.001; mesothelioma: r=.79, P<.001; testicular cancer: r=.57, P<.001; basal cell carcinoma: r=.83, P<.001). The monthly Baidu index was significantly correlated with cancer mortality rates for 24 of 27 cancers. In terms of the whole population, the number of women who searched for cancer-related information has slowly risen over time. People aged 30-39 years were most likely to use search engines to retrieve cancer-related knowledge. East China had the highest Web search volumes for cancer. CONCLUSIONS Search behaviors indeed reflect public awareness of cancer from a different angle. Research on internet search behaviors could present an innovative and timely way to monitor and estimate cancer incidence and mortality rates, especially for cancers not included in national registries.

AbstractThrombotic complications in hematologic malignancies have important clinical implications. In this meta-analysis we sought to obtain accurate estimates of the thrombotic risk in lymphoma patients. Articles were searched in electronic databases and references. Eighteen articles were identified (29 cohorts, 18 018 patients and 1149 events). Pooled incidence rates (IRs) were calculated by the use of a method based on the exact maximum likelihood binomial distribution. The global IR of thrombosis was 6.4% (95% confidence interval [CI] 6.0%-6.8%). The global IRs of venous or arterial events were 5.3% (95% CI, 5.0%-5.7%) and 1.1% (95% CI, 0.9%-1.2%), respectively. The IR of thrombosis observed in subjects with non-Hodgkin lymphoma (NHL) was 6.5% (95% CI, 6.1%-6.9%), significantly greater than that observed for patients with Hodgkin lymphoma (4.7%; 95% CI, 3.9%-5.6%). Within NHL, patients with high-grade disease had a greater risk of events (IR 8.3%; 95% CI, 7.0%-9.9%) than low-grade disease (IR 6.3%; 95% CI, 4.5%-8.9%). This meta-analysis shows that the IR of thrombosis in lymphoma patients is quite high, especially in those with NHL at an advanced stage of the disease. These results may help better defining lymphoma populations at high thrombotic risk, to whom prophylactic approaches could be preferentially applied.

Incidence And Mortality

Background: The present study aims to assess the incidence and mortality rates of gynecological cancers and their changes from 1990 to 2016 at national and subnational levels in Iran. Methods: Annual estimates of incidence and mortality for gynecological cancers from 1990 to 2016 at national and subnational levels were generated as part of a larger project entitled National and Subnational Burden of Diseases, Injuries, and Risk Factors (NASBOD). After the precise processing of data extracted from the Iran Cancer Registry, annual age-standardized incidence and mortality rates were calculated for each cancer, province, year and age group during the period of the study. Results: In 2016, gynecological cancers constituted 8.0% of new cancer cases among women of all ages compared to 3.7% of new cases of cancer among women in 1990. The incidence rate of gynecological cancers has increased from 2.5 (0.9-5.6) per 100000 women in 1990 to 12.3 (9.3–15.7) per 100000 women in 2016, and the most common gynecological cancer has changed from cervical cancer in 1990 to corpus uteri cancer in 2016. Age-standardized incidence rates of ovarian, corpus uteri and vulvovaginal cancers increased from 1.3 (0.5–2.4), 1.7 (0.6–3.0), and 0.3 (0.0–0.7) in 1990 to 4.4 (3.6–5.2), 9.9 (6.8–13.4), and 0.6 (0.2–1.0) in 2016, respectively, showing a 3.3, 5.8 and 1.7-fold increase during this period. Age-standardized incidence rate of cervical cancer was 2.4 (1.7–3.3) cases per 100000 women in 2016 and did not differ significantly from the beginning of the study. An overall reduction was seen in national mortality to incidence ratios (MIR) from 2000 to 2015. Conclusion: The incidence rates of all gynecological cancers in different provinces have shown a converging trend that could indicate that attempts toward health equality have been effective. The declining trend of MIR could be interpreted as advancements in detection of cancer in its early stages and also improvements in treatments, in turn reflecting improvements in access to and quality of care.

Background Follicular lymphoma (FL) is the most common indolent lymphoma and the 2nd most common non- Hodgkin lymphoma, accounting for 10%–20% of all lymphomas in the Western world. Epidemiologic and geographic trends of FL in Canada have not been investigated. Our study’s objective was to analyze incidence and mortality rates and the geographic distribution of FL patients in Canada for 1992–2010.Methods Demographic and geographic patient data for FL cases were obtained using the Canadian Cancer Registry, the Registre quebecois du cancer, and the Canadian Vital Statistics database. Incidence and mortality rates and 95% confidence intervals were calculated per year and per geographic area. Rates were plotted using linear regression models to assess trends over time. Overall data were mapped using Microsoft Excel mapping software (Redmond, WA, U.S.A.) to identify case clusters across Canada.Results Approximately 22,625 patients were diagnosed with FL during 1992–2010. The age-standardized incidence rate of this malignancy in Canada was 38.3 cases per million individuals per year. Geographic analysis demonstrated that a number of Maritime provinces and Manitoba had the highest incidence rates, and that the provinces of Nova Scotia and Quebec had the highest mortality rates in the nation. Regional data demonstrated clustering of FL within cities or regions with high herbicide use, primary mining, and a strong manufacturing presence.Conclusions Our study provides a comprehensive overview of the FL burden and its geographic distribution in Canada. Regional clustering of this disease in concentrated industrial zones strongly suggests that multiple environmental factors might play a crucial role in the development of this lymphoma.

SUMMARYDiarrhoea is a leading cause of morbidity and mortality yet diarrhoea specific incidence and mortality rates for older children, adolescents, and adults have not been systematically calculated for many countries. We conducted a systematic literature review to generate regional incidence rates by age and to summarize diarrhoea specific mortality rates for regions of the world with inadequate vital registration data. Diarrhoea morbidity rates range from 29·9 episodes/100 person-years for adults in the South East Asian region to 88·4 episodes/100 person-years in older children in the Eastern Mediterranean region and have remained unchanged in the last 30 years. Diarrhoea mortality rates decline as the child ages and remain relatively constant during adulthood. These data are critical for improving estimates worldwide and further highlight the need for improved diarrhoea specific morbidity and mortality data in these age groups.

Risk Of Cancer

Human Immunodeficiency Virus (HIV) infection is both infectious and contagious disease. The people infected with HIV have an increased risk of cancer while comparing with uninfected people. Kaposi’s sarcoma, aggressive B-cell Non-Hodgkin Lymphoma & cervical cancer are the three types of cancers which are termed as “HIV –associated cancers”. Apart from these cancers, HIV patients are prone to cancers of anus, liver, lung, pharynx which are termed as “non-AIDS defining cancers”. Viral oncogenesis and cytokine induced growth contribute to the development of Kaposi sarcoma. Several virally encoded genes such as bcl-2, IL-6, cyclin-D, GPCR & interferon regulatory factor, plays key role in cellular proliferation and survival.  Infection with HIV weakens the immune system and reduces the body’s ability to fight against viral infections that may lead to cancer. Immunosuppression and inflammation in HIV patients also contribute to cancer progression. The complications of AIDS- related cancers include easy bleeding and bruising, tiredness, nausea, vomiting, poor appetite, mouth sores, hair loss etc. According to the data, HIV infected males are more susceptible to Kaposi’s sarcoma and Non- Hodgkin Lymphoma whereas females are more liable to cervical cancers. Early diagnosis and treatment options help to drop the risk of AIDS related cancers. The HAART therapy reduces the risk of cancer in HIV patients by lowering the amount of HIV circulating in blood, so that function of immune system to fight against the virus can be restored. Other treatment methods are chemotherapy, immunotherapy, radiation and surgery.

Abstract Subtle differences in immune response may play a role in non-Hodgkin lymphoma (NHL) etiology. Because adult immune response may be influenced by early childhood exposures, we examined the role of childhood crowding, history of atopic disease, and other childhood immune-related exposures on the risk of non-Hodgkin lymphoma in a multi-center case-control study. Interviews were completed with 1,321 cases ascertained from population-based cancer registries in Seattle, Detroit, Los Angeles and Iowa, and with 1,057 frequency-matched controls, selected by random-digit dialing and from the Health Care Financing Administration (HCFA) database. The association between NHL risk in relation to atopy and other exposures was assessed using multivariable logistic regression methods. Most types of allergy were associated with protection from NHL, with hay fever especially protective against all NHL combined (Odds Ratio [OR] = 0.71, 95% confidence interval [CI]= 0.54–0.94), diffuse large B-cell lymphoma [DLBCL] (OR=0.61, 95% CI=0.41–0.91), and follicular lymphoma (OR=0.70, 95% CI=0.45–1.09). A history of eczema increased risk of follicular lymphoma (OR=1.92, 95% CI= 1.08–3.41) but not DLBCL (OR=1.06, 95% CI= 0.55.2.04). Asthma in childhood was not associated with risk of NHL. Risk of DLBCL (OR =1.72, 95% CI=1.17–2.52), but not follicular lymphoma (OR=1.15, 95% CI=0.75–1.76) was elevated for the youngest compared to the oldest of siblings. Neither number of siblings nor years between births of siblings were significantly associated with risk. These results suggest that some immune-related exposures may affect NHL risk.
