Prevalence of tobacco use among cancer patients in Iran: a systematic review and meta-analysis. BMC Public Health 2024; 24:1081. [PMID: 38637741 PMCID: PMC11027381 DOI: 10.1186/s12889-024-18594-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2023] [Accepted: 04/15/2024] [Indexed: 04/20/2024] Open
Abstract
BACKGROUND The prevalence of tobacco use among various cancer types in Iran remains a significant concern, necessitating a comprehensive analysis to understand the extent and patterns of consumption. This study aimed to systematically review and analyze existing literature to delineate the prevalence of tobacco use across different cancer types in Iran, thereby providing a robust basis for future interventions and policy formulations. METHODS Adhering to the PRISMA guidelines, we conducted a systematic review and meta-analysis of literature available in PubMed and Scopus databases. The initial search identified 351 records, out of which 44 studies were selected based on their relevance and design. These studies spanned various time frames, starting from the 2001s up until 2022, and encompassed diverse geographical locations and cancer types in Iran. To avoid bias and potential data overlap, we opted to incorporate a single comprehensive study from the Golestan Cohort, encompassing all data, while excluding 10 other studies. Our final analysis incorporated data from 34 studies, which accounted for 15,425 patients and 5,890 reported smokers. Statistical analyses were performed to calculate the overall proportion of tobacco consumption and to conduct subgroup analyses based on different variables such as cancer types, gender, geographical locations, and types of tobacco used. RESULTS The analysis revealed a substantial prevalence of tobacco use among cancer patients in Iran, with an overall consumption rate of 43%. This rate varied significantly, ranging from 10 to 88% across individual studies. Subgroup analyses further highlighted disparities in tobacco consumption rates across different demographics, geographic areas, and cancer types. Notably, the 'ever' smokers category exhibited the highest prevalence of tobacco use. The study also identified a worrying trend of high cigarette smoking rates, along with variable consumption patterns of other forms of tobacco, including waterpipe, 'Naas', and 'Pipe'. CONCLUSIONS This systematic review and meta-analysis underscores a significant association between tobacco consumption and various cancer types in Iran, with a prevalence rate among cancer patients being three times higher than the average Iranian population. The findings indicate substantial heterogeneity in tobacco use patterns, emphasizing the need for targeted interventions to address this pressing health issue. The study serves as a critical resource for shaping future policies and strategies aimed at curbing tobacco use and mitigating its adverse effects on cancer prevalence in Iran.

Ren K, Wang B, Qi Q. Development of a new EGFR antibody antagonist which exhibits potential biological effects against laryngeal cancer. ANNALS OF TRANSLATIONAL MEDICINE 2021; 9:964. [PMID: 34277764 PMCID: PMC8267258 DOI: 10.21037/atm-21-1839] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/25/2021] [Accepted: 05/28/2021] [Indexed: 12/22/2022]
Abstract
Background Laryngeal cancer is a common malignant tumor of the head and neck. Clinical treatment methods mainly include radiotherapy and chemotherapy, but the toxicity and side effects of these treatments seriously affect the quality of life of patients. Currently, there are no specific anti-laryngeal cancer drugs available. Therefore, it is necessary to develop new targeted drugs for laryngeal cancer. Methods We established a cell model of laryngeal cancer in vitro and a TU686 xenograft model in vivo. We then carried out the related research through a series of experiments [including laser confocal microscopy, enzyme linked immune sorbent assay (ELISA) and Western blot]. Results The results showed that the epidermal growth factor receptor (EGFR) antibody antagonist 6E-C could not only specifically bind to EGFR, but also specifically inhibit the binding of EGF to EGFR. Further analysis indicated that 6E-C could inhibit the EGFR-mediated intracellular signaling pathway. Furthermore, 6E-C inhibited xenograft tumor growth in vivo. Conclusions In summary, we have successfully prepared a new anti-EGFR antibody antagonist, which exhibited anti-laryngeal cancer effects in vitro and in vivo. The current research demonstrates that the EGFR antibody antagonist 6E-C shows potential as an effective anti-laryngeal cancer agent, with potential clinical application value. This study therefore provides a solid foundation for related research in the future.

Abstract
BACKGROUND Laryngeal malignancy is a common malignancy of the head and neck region. Affected patients usually present with features that are characteristic of certain subsites. The larynx is oncologically divided into three: supraglottis, glottis and subglottis. Studies from Western countries have shown that the glottis is the commonest subsite to harbour laryngeal malignancy. However, the supraglottis has been reported to be the commonest subsite in developing countries, including examples in the Indian subcontinent. To our knowledge, no study has been carried out in western Nepal about the epidemiology of laryngeal cancer to date. The purpose of this study was to analyse the epidemiology of laryngeal cancer in relation to its risk factors, age distribution,and preferred subsites and to see if there is any recent change in the subsite wise distribution of laryngeal malignancy in western Nepal. MATERIALS AND METHODS Patients of all ages and both sexes with suspected laryngeal malignancy were enrolled in the initial study. Detailed history taking and clinical examination was performed to find out the involved subsite in relation to the clinical features. Direct laryngoscopy was performed to further confirm the subsite and to take biopsy from the growth under general anesthesia. After confirmation of malignancy from the biopsy report, patients were finally included in the study. Data were analysed and observations were made to find out the distribution of laryngeal malignancy in different subsites. RESULTS The supraglottic larynx was the commonest subsite to harbor laryngeal malignancy. Smoking and alcohol were found to be the common risk factors. The mean age of the patients was in their sixties. CONCLUSIONS Laryngeal malignancy is common in elderly individuals. Supraglottic laryngeal malignancy is the commonest laryngeal malignancy in people who smoke and drink alcohol in Nepal. Avoidance of alcohol use and smoking will be a milestone to reduce the incidence of laryngeal cancers and associated mortality.

Abstract
One major objective for our evolving understanding in the treatment of cancers will be to address how a combination of diagnosis and treatment strategies can be used to integrate patient and tumor variables with an outcome-oriented approach. Such an approach, in a multimodal therapy setting, could identify those patients (1) who should undergo a defined treatment (personalized therapy) (2) in whom modifications of the multimodal therapy due to observed responses might lead to an improvement of the response and/or prognosis (individualized therapy), (3) who might not benefit from a particular toxic treatment regimen, and (4) who could be identified early on and thereby be spared the morbidity associated with such treatments. These strategies could lead in the direction of precision medicine and there is hope of integrating translational molecular data to improve cancer classifications. In order to achieve these goals, it is necessary to understand the key issues in different aspects of biotechnology to anticipate future directions of personalized and individualized diagnosis and multimodal treatment strategies. Providing an overview of translational data in cancers proved to be a challenge as different methods and techniques used to obtain molecular data are used and studies are based on different tumor entities with different tumor biology and prognoses as well as vastly different therapeutic approaches. The pros and cons of the available methodologies and the potential response data in genomics, microRNA, epigenetics and proteomics with a focus on upper gastrointestinal cancers are considered herein to allow for an understanding of where these technologies stand with respect to cancer diagnosis, prognosis and treatment.

[PMID: 26082901 PMCID: PMC4461843] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Subscribe] [Scholar Register] [Received: 06/25/2014] [Accepted: 08/12/2014] [Indexed: 11/18/2022]
Abstract
INTRODUCTION The purpose of this study was to investigate the relationship between serum levels of interleukin-6 (IL-6) and the severity and extent of squamous cell carcinoma (SCC) of the larynx based on stage of tumor progression and histological grade. MATERIALS AND METHODS All patients with a diagnosis of laryngeal cancer who underwent laryngoscopy and biopsy while hospitalized in Imam Khomeini Hospital in Ahvaz were enrolled. Tumor stage was calculated based on the TNM system, and divided into early (stage 1,2) or advanced stage (stage 3,4). In addition, patients were divided into low-grade (well differentiated) or high-grade (moderate and poorly differentiated) groups based on pathology reports from biopsy specimens. Several healthy volunteers were also enrolled as the control group. After collecting the blood samples, quantitative serum levels of IL-6 were measured (pmol/L) using IL-6 kits (Bender MedSystem, Germany). Results for quantitative variables are presented as mean and standard deviation and qualitative variables as percentages. Mann-Whitney, Kruskal-Wallis and Pearson's chi square tests were used for statistical analyses. P<0.05 was considered statistically significant. Statistical analysis of data was performed using SPSS version 13. RESULTS Thirty-eight patients (82.6%) were male and eight patients (17.4%) were female. IL-6 serum level was 28.8±4.7 pmol/L in the patient group and 2.64±2.88 pmol/L in the control group (P=0.0001). The serum level of IL-6 was 7.27 ± 5.31 pmol/L in early-stage patients and 54.43 ± 6.06 pmol/L in advanced-stage patients (P<0.0001). IL-6 levels increased significantly with increasing N (according to TNM) (P=0.002). Levels of IL-6 in patients with metastasis were significantly higher than in the group without metastasis (P=0.024). Moreover, IL-6 levels increased significantly with increasing local tumor spread (T) (P<0.0001). CONCLUSION This study shows that IL-6 is a gender-independent factor, serum levels of which are higher in patients with laryngeal SCC than in normal subjects. The results of this study also show that serum levels of this cytokine increase significantly with progression of this malignancy.

Abstract
INTRODUCTION As one of the most common cancers among head and neck malignancies, cancer of the oral cavity probably has some variations in countries with a high prevalence of esophageal cancer. MATERIALS AND METHODS Patients with oral cavity cancer who were treated at two tertiary referral centers from January 1999 to January 2009 were included in this study. In addition to demographic data, information regarding personal and family history of head and neck cancer, use of dentures, presence of immune deficiency, consumption of alcohol, and incidence of cigarette smoking was collected. Additionally, a history of opium usage was obtained from the participants in this study. Moreover, an appropriately matched control group was selected for comparisons between the risk factors. RESULTS A total of 557 patients were entered into this study over a 10-year period, of whom 219 (39.3%) were female and the remaining 338 (60.7%) were male. The tongue was the most common site of cancer and 9% of the patients had a history of opium abuse, but more than half of the patients did not have any recognized risk factors. The incidence and stage of cancer had a significant relationship with cigarette smoking (P= 0.013). CONCLUSION Tongue cancer in non-smokers is the predominant pattern of oral cavity cancer in Iran.
