Effectiveness of a Fully Automated Internet-Based Smoking Cessation Program: A Randomized Controlled Trial (STAMP).

Introduction: The Internet offers an interesting alternative to face-to-face and telephone-based support for smoking cessation. This study was designed to assess the effectiveness of a personalized and automated Internet-based program. Methods: French current adult smokers willing to quit within 2 weeks were recruited for a randomized controlled trial. The intervention consisted of an automated program of 45 e-mails ("e-coaching") sent over a 3-month period. The control group received a PDF version of a booklet on smoking cessation. Self-reported 7-day point prevalence smoking abstinence was measured at 6 months (primary outcome), at 3 and 12 months of follow-up (secondary outcomes). Results: 2478 smokers were randomized (1242 for e-coaching, 1236 for the booklet). Cessation rate in the intention-to-treat population was not significantly different between the two groups at 6 and 12 months, but was higher in the e-coaching group at 3 months than in the control group (27.5% vs. 23.5%, p = .02, odds ratio [OR] = 1.24, confidence interval [CI] = [1.03-1.49]). After adjustment for baseline conditions, the effect of the intervention in the per-protocol (PP) sample was significant at 3 months (adjusted odds ratio [aOR] = 1.72 [1.31-2.28], p < .001, N = 1042) and at 6 months (aOR = 1.27 [1.00-1.60], p = .05, N = 1082). GLM repeated measure analyses showed significant group by time interaction in the intent-to-treat and a significant group effect in the PP population. Conclusions: Analyzed intention-to-treat, e-coaching was superior to a booklet at 3 months (end of intervention) but no more superior at 6 and 12 months follow-up. Among those who actually followed the program, the effectiveness is also observed 3 months after the intervention is stopped. Implications: Analyzed intention-to-treat, our French tailored and personalized Internet-based cessation program was superior to a smoking cessation booklet at 3 months (end of intervention) but no more superior at 6 months follow-up. Among those who actually followed the program (PP population), the effectiveness is observed in the short-term but also 3 months after the intervention is stopped.

Factors associated with deferral or non-performance of an organized breast cancer screening program during the COVID-19 pandemic in France.

BACKGROUND: Delays in detection and treatment of breast cancer can lead to increased mortality. To date, participation in organized breast cancer screenings (OBCS) has been suboptimal worldwide. The objective of this study was to investigate the factors associated with deferral or non-performance of mammography during the COVID-19 pandemic for women who had previously participated in OBCS. METHODS: A retrospective observational study was conducted on a cohort of 6282 women from the Aube Department of France, who were invited to an OBCS in 2020. Participants were divided into women who promptly underwent screening after receiving an invitation (between 22 and 25 months elapsed since the last mammogram), women who underwent late screening (≥26 months since the last mammogram), and those who were never screened. Data were collected from a self-reported questionnaire. Comparative and multivariable analyses modeling the probability of each type of attendance were performed using these data. RESULTS: In total, 2301 women (aged 50-74 years) returned a valid questionnaire. Compared to women who promptly underwent mammography, non- and late-screening participants were younger, had less frequent gynecological follow-up and a less frequent history of colorectal cancer screening. Women with higher education status and those residing in socially disadvantaged areas were more likely to attend late. CONCLUSION: The absence of regular gynecological follow-up and the absence of colorectal cancer screening were significant factors associated with deferral of or non-attendance at OBCS.

Care pathway of women with interval breast cancer in 2016, based on medico-administrative data.

BACKGROUND: Since 2004, an organised screening programme (OS) for breast cancer has been in place for 50-74 years women who are not at an increased risk. Despite this, 17% of cancers diagnosed within 24 months following an OS mammogram are interval cancers (IC), diagnosed even though the OS had not reported cancer. After identifying IC from the French administrative healthcare database (SNDS), our objective was to describe the care pathways of women with IC in 2016. MATERIALS AND METHODS: The IC identification algorithm is based on breast imaging tests conducted in the 24 months prior to diagnosis and on the compatibility of their timeline with ACR3 lesion follow-up (BIRADS guidelines). The care pathways of 3 groups were compared: women with IC, diagnosed through the OS, and diagnosed outside the OS programme (personalised screening or based on clinical signs, PSCS group). RESULTS: Respectively, 12,965 (46%), 3433 (12%), and 11,761 women (42%) were classified in the OS, IC and PSCS groups, i.e. 20.9% IC cases among the women taking part in the OS programme. The women from the IC group presented with more forms with lymph node or metastatic involvement than those of the OS group. Their pathways were more complex than in the OS group: at an equivalent stage, more total mastectomies and more adjuvant or neoadjuvant chemotherapy regimens. CONCLUSION: The care pathways of women with IC are intermediate with respect to those of the OS or PSCS group.Cases of IC probably include several cancer prognosis profiles.
