Abstract
Background Laryngeal cancer is a common malignancy of the head and neck, especially in
northern China, including Shanxi province. This study intends to describe
the epidemiological characteristics of laryngeal cancer in Shanxi Province,
China, in order to support prevention and treatment efforts. Methods Retrospective analysis of the medical records of patients diagnosed with
laryngeal cancer in hospitals in Shanxi Province from 2008 to 2012. Results The average annual incidence rate of laryngeal cancer in Shanxi province from
2008 to 2012 was 0.70/105, the Chinese population standardized
incidence rate was 0.57/105 and the world population standardized
incidence rate was 0.60/105. The city with the highest incidence
of laryngeal cancer in Shanxi Province is Taiyuan, followed by Yangquan, and
the lowest incidence are Yuncheng and Jincheng. The cases included 723
farmers (58.6%), 338 workers (27.4%), 95 government cadres (7.7%), 35
unemployed individuals (2.8%), 30 teachers (2.4%) and 13 individuals with
other occupations (1.1%). The incidence of laryngeal cancer in rural areas
was 0.78/105, while urban areas was 0.60/105. Of 1006
patients with smoking and drinking status reported, there were 238 both
smoking and drinking (23.7%), 491 only smoking but not drinking (48.8%), 4
only drinking but not smoking (0.4%), 273 both not smoking and not drinking
(27.1%) (P<0.001), and there were 695 males smoking (95.3%), 34 females
smoking (4.7%) (P<0.001). Of 879 patients for whom the primary cancer
location was known, 406 cases (46.2%) were supraglottic and 428 cases
(48.7%) were glottic. Among 1009 patients with known pathological
classification, the vast majority had squamous cell carcinoma (992 cases,
98.3%). Conclusions To sum up, the incidence of laryngeal cancer in Shanxi Province exhibited a
relatively stable trend from 2008 to 2012, and the incidence is higher in
men than in women in all years. The high percentage of smokers in this study
underscores the importance of smoking as a risk factor for laryngeal cancer,
whereas rates of drinking did not appear to be linked. Incidence of
laryngeal cancer was higher in rural areas than in urban areas, a pattern
that differs from other regions of China and internationally.

ENVIRONMENTAL SCIENCE AND POLLUTION RESEARCH INTERNATIONAL 2020; 27:39274-39282. [PMID: 32642903 DOI: 10.1007/s11356-020-09948-x] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/02/2020] [Accepted: 06/29/2020] [Indexed: 06/11/2023]
Abstract
Epidemiological evidence has suggested that ambient air pollution is an increasingly important risk factor for respiratory diseases without assessing its influence on laryngeal neoplasms incidence in China. We constructed two-way fixed effect models and Poisson regression models to explore the effects of ambient air pollutants including nitrogen dioxide (NO2), sulfur dioxide (SO2), and particulate matter less than or equal to 10 μm in aerodynamic diameter (PM10) on incidence of laryngeal neoplasms in twelve major cities in China over the period 2006-2013. The annual average concentration for PM10, SO2, and NO2 was 107.22 μg/m3, 44.07 μg/m3, and 46.71 μg/m3 with standard deviations of 24.84 μg/m3, 13.68 μg/m3, and 9.19 μg/m3, respectively. We observed that ambient air pollutants were significantly positively correlated with the incidence of laryngeal neoplasms, especially for NO2. The relative risks of overall incidence of laryngeal neoplasms in the current period were 1.20, 1.04, and 1.00 for NO2, SO2, and PM10, with 95% confidence intervals (CIs) of 1.01-1.43, 0.93-1.16, and 0.96-1.05, respectively. Moreover, this deleterious impact was stronger in the male than in the female, likely due to genetic predisposition caused by longer exposure to more serious air pollution for men. Our findings complement the epidemiological evidence of laryngeal neoplasms due to ambient air pollution and reinforce the necessity of policy efforts to control the noxious air pollution emissions.

Abstract
PURPOSE to describe the clinical and sociodemographic profile and analyze the voice rehabilitation outcomes of patients with laryngeal cancer. METHODS cross-sectional study with 204 individuals with laryngeal cancer treated between 1989 and 2015. The variables describing the patients' profile were presented in absolute values (n) and percentage (%). The association between the speech-language therapy outcome and the sociodemographic and clinical characterization variables was verified by means of uni- and multivariate techniques. RESULTS 95.1% of the patients are male; 53.43% are aged 60 or more; 77.37% have elementary education; 44.12% are in the service industry; 81.63% smoke and consume alcohol; 30.4% are stage T3. Absence of nodules was found in 72.00%, and of metastasis, in 85.6% of patients. The most frequent therapeutic procedure was complete or partial laryngectomy (69.61%). There was an association among education, disease stage, habits, and therapeutic outcome with speech-language therapy (p<0.001). CONCLUSION Several causes can affect the prognosis of vocal rehabilitation in patients with laryngeal cancer. Optimization and diversification of new therapeutic procedures are challenges for these patients' speech-language rehabilitation.

Abstract
OBJECTIVE To analyze the incidence and mortality rates of laryngeal cancer in China from 2008 to 2012. METHODS Incident and death cases of laryngeal cancer were retrieved from the National Central Cancer Registry (NCCR) database collecting from 135 cancer registries in China during 2008-2012. The crude incidence and mortality rates of laryngeal cancer were calculated by area (urban/rural), region (eastern, middle, western), gender and age group (0, 1-4, 5-9, …, 85+). China census in 2000 and Segi's world population were applied for age standardized rates. JoinPoint (Version 4.5.0.1) model was used for time trend analysis. RESULTS The crude incidence rate of laryngeal cancer was 1.86/100,000 ranked the 21st in overall cancers. The age-standardized incidence rates by China population (ASIRC) and by World population (ASIRW) were 1.22/100,000 and 1.23/100,000, respectively. The crude mortality of laryngeal cancer in China was 1.01/100,000 and it was the 21st cause of cancer-related death in overall cancers. Both the age-standardized mortality rates by Chinese standard population (ASMRC) and by world standard population (ASMRW) were 0.63/100,000. Incidence and mortality rates of laryngeal cancer were higher in males than in females and higher in urban areas than in rural areas. Middle areas had the highest incidence and mortality rates followed by eastern and western areas. Incidence and mortality rates of laryngeal cancer retained low level before age of 40 years old but increased greatly after and peaked in age group of 75. Incidence showed significant down trends in recent 10 years by 1.27% annually [95% confidence interval (95% CI): -2.2%, -0.3%]. Mortality declined in females sharply by 5.18% per year although stable in males and both sexes combined. CONCLUSIONS Appropriate targeted prevention, early detection and treatment programs should be carried out to control the local burden of laryngeal cancer.

Abstract
Background: Cancer is one of the most prevalent causes of mortality worldwide. In the cervix it is considered to be caused by different high-risk human papillomavirus (HPV) types. Although many studies have already been conducted worldwide on the epidemiology of HPV infection and their oncogenic properties, limited data are available on HPV prevalence, incidence and genotype specific dissemination in Kazakhstan. Methods: To review the distribution of HPV infection, electronic databases (e.g. PubMed, Web of Science and Google Scholar) were searched for peer reviewed articles in English. The study was performed during June-July 2017 with a review of 39 relevant articles, published up to July 31, 2017. The following inclusion criteria were applied: general population data, cytology results available, and use of polymerase chain reaction (PCR) and/or Hybrid Capture® 2, Digene Corp., USA for HPV detection. Results: As reported in limited studies, the prevalence of HPV infection in Kazakhstan ranges from 43.8% to 55.8%. However, the scenario with regard to epidemiology of HPV related cancers in Kazakhstan is not very clear. One study reported a decline of laryngeal cancer observed during the recent years, whereas cervical cancer incidence has increased to about 3000 new cervical cancer cases, and about 1,000 cervical cancer deaths each year. Conclusion: The high incidence of cervical cancer with a significant mortality rate in Kazakhstan is evidence of HPV infection abundance despite an absence of HPV screening and low public awareness of the problem. Having a well-informed understanding of the role of HPV infection could enhance the public’s acceptance of screening and intervention programs to reduce morbidity and mortality in the country due to HPV infection. Thus, the purpose of this review article is to summarize the existing data, identifying directions for future research on HPV epidemiology and HPV-related diseases in Kazakhstan.

Abstract
The present study reports the case of a 53-year-old man with leptomeningeal metastasis from early glottic laryngeal cancer. The patient had been diagnosed with squamous cell carcinoma of the glottic larynx 9 years previously. The current symptoms included a recurring headache that had persisted for 1 month and vomiting for 1 week. A magnetic resonance imaging scan of the head revealed multiple enhancing lesions in the brain and multiple line-like enhancements in the brain fold. Computed tomography scans of the head, neck, chest and abdomen showed no nodular lesions. Cytological examination of the cerebral spinal fluid (CSF) revealed malignant cells with a scattered distribution pattern. The patient received intra-CSF methotrexate chemotherapy concurrent with whole-brain radiotherapy, which relieved the neurological symptoms. To the best of our knowledge, this is the first case of cytologically-confirmed LM from early glottic laryngeal cancer.

Abstract
While several reproductive and lifestyle-related factors are already well-known as established risk factors for breast cancer, environmental factors have attracted attention only recently. The objective of the current study was to assess the association between the breast cancer incidences in females, the mortality rate and the number of motor vehicles on the one side and the consumption of gasoline which could work as a major source of air pollution at the other side. The breast cancer incidences and the mortality trends were compared with various indices of westernization like dietary patterns or industrialization with 10 years lag of time. Geographical variations with 10, 15 and 20 years lag of time were assessed between the breast cancer incidence in 2010 and the number of motor vehicles as well as the consumption of gasoline. The upward trend of motor vehicle numbers proved to be comparable to those of breast cancer incidence and mortality. However, the consumption of gasoline started to decrease since the mid-1990s. The geographic distribution of motor vehicle numbers and gasoline consumption in 1990 is in a positive correlation with the breast cancer incidence rates in 2010 and the 20-year lag time (R2 0.379 with the number of motor vehicles and 0.345 with consumption of gasoline). In a linear relationship between the breast cancer incidences in 2010 and the log transformed number of motor vehicles, the log transformed consumption of gasoline in 2000 also showed a positive relationship (R2 0.367 with the number of motor vehicles and 0.329 with consumption of gasoline). The results of the current study indicate that there may be a positive relation between the number of vehicles, gasoline consumption and the incidence of breast cancer from the aspects of long-term trends and geographical variation.

Abstract
Cancer is a major health problem facing the entire world, and Kazakhstan is not the exception. The aim of this study was to present an epidemiological assessment of leukemia in the population of Kazakhstan during 2003-2012. This descriptive and retrospective study was based on data obtained from all oncological organizations of the whole country. Age standardized incidence rates per 100,000 population for leukemia were calculated. Totally, 6,741 new cases of leukemia were registered in Kazakhstan during the 10 year period. The mean age of patients with leukemia was 48.5. The ASRs for leukemia among men and women were 5.3 and 3.6, respectively (p<0.001). In conclusion, our results showed a high incidence rate of leukemia in Kazakhstan, especially in the north of the country. The incidence of leukemia was significantly higher in males and increased with age. Determining and controlling important risk factors of leukemia may lead to decrease in its burden.

Abstract
In the article were observed the epidemiological aspects of malignant tumors of the central nervous system (MT CNS) in Kazakhstan in a retrospective study for the years 2004-2011. The material of the study was consolidated accounting data of oncology centers on patients with MT CNS (C70-72) with first time established diagnosis. Calculated were crude, age, standardized (world standard), aligned and predicted incidence of MT CNS among both male and female populations. It was found that over the studied period, there were 4,604 cases of MT CNS. The average annual crude incidence rate of MT CNS in total population was 3.7±0.10/0000. Trends in aligned incidence rates in the whole country had a tendency to increase (T=+0.9%). Defined levels of morbidity MT CNS in the whole population in different regions of Kazakhstan: low up to 2.870/0000, the average from 2.87 to 4.450/0000 and high from 4.450/0000 and above on the basis of which was given the space-time estimate. Age and sex differences in MT CNS incidence were also clearly established.
