Nearly one in 10 cancer survivors reports smoking many years after a diagnosis, according to a new study. 2020 Oct;25(10):1786-1792. doi: 10.1007/s10147-020-01733-7. Smoking at time of diagnosis and breast cancer-specific survival: new findings and systematic review with meta-analysis. The 10% of women who continued to smoke after diagnosis were more likely than never smokers to die of breast cancer (HR, 1.72; 95% CI, 1.13 to 2.60). The median time between diagnosis and completion of the CBCS questionnaire was approximately 16 months (interquartile range, 12 to 19 months). Why is this study important? Alcohol consumption before and after breast cancer diagnosis: associations with survival from breast cancer, cardiovascular disease, and other causes. 2014 Apr 19;16(2):R42. 2, 3, 6, 8, 9 Current smoking was reported to be associated with a higher risk of all‐cause 3 and breast … Behavioral risk factors, such as smoking, affect survival. It is possible that cancer survivors may misrepresent their smoking status.38 However, the observed prevalence of current smoking among long-term breast cancer survivors (10%) was consistent with previous reports.39,40 Participants were provided only a single occasion to report postdiagnosis smoking habits, and we do not know whether women who reported actively smoking at the time of the CWLS questionnaire quit smoking thereafter.

Authors' disclosures of potential conflicts of interest are found in the article online at www.jco.org. Postdiagnosis assessments of smoking habits are frequently missed, both in the clinic and as part of follow-up in longitudinal research studies , making it a challenge to estimate any association with change in smoking behavior. The 10% of women who continued to smoke after diagnosis were more likely than never smokers to die of breast cancer (HR, 1.72; 95% CI, 1.13 to 2.60). Bérubé, S et al. Prevention and treatment information (HHS). As for breast cancer‐specific death as an outcome, current smokers are reported to have a higher risk than those who had never smoked, 2, 3, 6, 8, 9 whereas other studies fail to find such an association for current 4, 5 or past smoking.

Together with Dartmouth College, I hold a use patent for the colorectal chemopreventive use of aspirin. But the role of nicotine in … Although not statistically significant, the women who quit smoking after their breast cancer diagnosis had 33% lower risk of death as a result of breast cancer than did women who continued to smoke after diagnosis. Smoking is known to increase the risk that breast cancer will spread, which lowers the survival rate by one-third at diagnosis. TAPUR Study, Terms of Use | Privacy Policy | The assumption of proportion hazards was examined by testing for the statistical significance of interactions with log-transformed survival time.

Conquer Cancer Foundation ICD-9 and ICD-10 codes for these five groups are summarized in Appendix Table A1 (online only). Table 1. The study enrolled women with incident invasive breast cancer diagnosed from age 20 to 74 years from 1988 to 1991, to age 79 years from 1992 to 1996, and to age 69 years from 1997 to 2008. Smoking causes about 20% of all cancers and about 30% of all cancer deaths in the United States. Postdiagnosis quitters had a 9% lower risk of death as a result of all causes than postdiagnosis smokers; this difference included a statistically significant 60% lower risk of death from respiratory cancer and a 20% lower risk of death as a result of cardiovascular disease. Passarelli, Newcomb, Hampton, Trentham-Dietz, Titus, Egan, Baron, Willett At Life Science Network we import abstract of articles published in the most popular journals. | JCO Oncology Practice Associations were strongest for women still smoking after breast cancer diagnosis and who had heavy usage (Table 5). The Life After Cancer Epidemiology study enrolled women with breast cancer, on average, approximately 2 years after diagnosis (observing 244 deaths as a result of breast cancer among 2,258 with the disease) and reported a strong association with breast cancer–specific mortality for smokers relative to never smokers at their baseline assessment (HR, 2.01; 95% CI, 1.27 to 3.18).19 In contrast, we used separate baseline and postdiagnosis assessments, which permitted us to distinguish prediagnosis and postdiagnosis quitters among former smokers. The association of smoking with outcomes following breast cancer prognosis is not well understood. Former smokers with less than 20 pack-years of exposure had no increased risk of any outcome. Of 5,784 CWLS participants, a total of 5,168 were available for analyses after the exclusions we imposed on women in the CBCS. During a median follow-up of 11 years from return of the postdiagnosis questionnaire, 988 deaths occurred. Participants included 20,691 women, ages 20 to 79 years, diagnosed with incident localized or regional invasive breast cancer between 1988 and 2008; a subset of 4,562 of these women were recontacted a median of 6 years after diagnosis. Several studies have linked prediagnosis smoking history to higher risk of death as a result of breast cancer,13-23 but very little is known about women who continue to smoke after diagnosis. 1315-1322. ASCO Meetings Knowing about all of the problems … 2. The median time between diagnosis and completion of the CWLS questionnaire was approximately 6 years (interquartile range, 3 to 9 years). Within 10-15 years after you quit smoking, your risk of lung cancer drops by half. Smoking now or smoking in the past has been found to significantly increase the risk that breast cancer will spread, and eventually cause death. §HR stratified by age at diagnosis, study phase, state of residence, and stage at diagnosis and adjusted for education, body mass index, parous status, age at first birth, menopausal status, use of postmenopausal hormone therapy, mammography history, alcohol consumption, and first-degree family history of breast cancer. Subscribers The association of smoking with outcomes following breast cancer prognosis is not well understood. When compared with women who continued to smoke after diagnosis, those who quit smoking after diagnosis had lower mortality from breast cancer (HR, 0.67; 95% CI, 0.38 to 1.19) and respiratory cancer (HR, 0.39; 95% CI, 0.16 to 0.95). The CWLS subcohort was generally similar to the entire CBCS cohort with regard to baseline characteristics, including age (mean, 59 years for CWLS v 58 years for CBCS) and stage at breast cancer diagnosis (73% localized for CWLS v 68% localized for CBCS; Appendix Table A3).

Half of the women had ever smoked, and 20% reported actively smoking 1 year before breast cancer diagnosis. Smoking can cause non-cancerous lung disease and cardiovascular disease. On the basis of the CBCS and CWLS designs, the postdiagnosis subcohort included women with varied lengths of time since diagnosis. In this study, we evaluated the association of smoking, as reported 2–4 months after diagnosis, with breast cancer‐specific and other‐cause mortality among breast cancer survivors. JCO OP DAiS, ASCO eLearning Robert Hiatt. COVID-19 is an emerging, rapidly evolving situation. Nine women reported smoking after diagnosis who did not indicate smoking before diagnosis. Relationships may not relate to the subject matter of this manuscript.
