This study aims to evaluate the association between smoking exposure and human papillomavirus (HPV)-related cervical abnormalities among women living with HIV (WLWH). By conducting a systematic review of the current literature, we evaluated the association between current active smoking and/or exposure to secondhand smoke (SHS) and the risk of cervical HPV incidence, prevalence, and clearance, as well as high-grade cervical intraepithelial neoplasm (HGCIN) incidence, prevalence, progression, [...]

Curiel-García, Teresa ; Candal-Pedreira, Cristina ; Varela-Lema, Leonor ; Rey-Brandariz, Julia ; Casal-Acción, Beatriz ; Moure-Rodríguez, Lucía ; Figueiras, Adolfo ; Ruano-Ravina, Alberto ; Perez-Rios, Monica

Introduction: Occupational exposure role on small cell lung cancer (SCLC) onset has been little studied. Wood dust has been recognized as a human carcinogen, and many occupations have high wood-dust exposure. The aim of this study was therefore to perform a systematic review and meta-analysis of the scientific literature to summarize and analyse the risks of wood dust-related occupations on development of SCLC, taking tobacco use into account. Methods: We conducted a literature search of [...]

Menée en Finlande sur la période 1990-2018 par questionnaire auprès d'une cohorte de 6 804 jumelles (âge moyen : 43,6 ans), cette étude analyse l'association entre le travail posté de nuit et le risque de cancer du sein (407 cas)

Breast cancer is highly prevalent yet a more complete understanding of the interplay between genes and probable environmental risk factors, such as night work, remains lagging. Using a discordant twin pair design, we examined the association between night shift work and breast cancer risk, controlling for familial confounding. Shift work pattern was prospectively assessed by mailed questionnaires among 5,781 female twins from the Older Finnish Twin Cohort. Over the study period (1990–2018), 407 [...]

Menée auprès de 530 témoins et 530 jeunes militaires de l'US AirForce présentant une tumeur germinale du testicule diagnostiquée sur la période 1990-2018 (âge moyen au diagnostic : 30 ans), cette étude analyse l'association entre l'exercice d'une profession militaire et le risque de développer la maladie

Military occupation and testicular germ cell tumour risk among US Air Force servicemen

Denic-Roberts, Hristina ; McGlynn, Katherine ; Rhee, Jongeun ; Byrne, Celia ; Lang, Michael ; Vu, Paul ; Purdue, Mark ; Rusiecki, Jennifer

Objectives: Testicular germ cell tumours (TGCTs) are the most commonly diagnosed malignancy among active duty US military servicemen. Occupational risk factors may play a role in TGCT aetiology, although the evidence is inconclusive. The objective of our study was to investigate associations between military occupations and TGCT risk among US Air Force (USAF) servicemen. Methods: This nested case–control study among active duty USAF servicemen obtained information on military occupations for [...]

Menée aux Etats-Unis auprès de 200 témoins et 200 patients atteints d'un cancer du côlon, cette étude analyse l'association entre les niveaux d'anticorps IgG agissant contre 11 espèces bactériennes orales et le risque de développer la maladie

Deberin, Julia ; Teles, Flavia ; Martin, Lynn M. ; Lu, Jiayun ; Koestler, Devin C. ; Kelsey, Karl T. ; Beck, James D. ; Platz, Elizabeth A. ; Michaud, Dominique S.

Periodontitis has been associated with an increased risk for gastrointestinal cancers. The objective of this study was to investigate the association of antibodies to oral bacteria and the risk of colon cancer in a cohort setting. Using the CLUE I cohort, a prospective cohort initiated in 1974 in Washington County, Maryland, we conducted a nested case-control study to examine the association of levels of IgG antibodies to eleven oral bacterial species (thirteen total strains) with risk of colon [...]

Risk factors for cancer of unknown primary: a literature review

Hermans, Karlijn E. P. E. ; Kazemzadeh, Fatemeh ; Loef, Caroline ; Jansen, Rob L. H. ; Nagtegaal, Iris D. ; van den Brandt, Piet A. ; Schouten, Leo J.

Cancer of Unknown Primary (CUP) is metastatic cancer with an unidentifiable primary tumour origin during life. It remains difficult to study the occurrence and aetiology of CUP. Hitherto, it is unclear whether risk factors are associated with CUP, yet identifying these factors could reveal whether CUP is a specific entity or a cluster of metastasised cancers from various primary tumour origins. Epidemiological studies on possible CUP risk factors were systematically searched in PubMed and Web [...]
