Impact of cancer diagnosis on use of smokeless tobacco: A descriptive study of patient-relative dyads.

BACKGROUND

The time of cancer diagnosis is considered as a teaching moment with regard to tobacco cessation.

AIM: In view of the limited studies focussing on smokeless tobacco (SLT), we aimed to assess the patterns of SLT use, attitudes toward SLT use in the context of cancer diagnosis, and factors associated with quitting SLT in dyads consisting newly diagnosed patients with head and neck cancers and their relatives.

MATERIAL AND METHOD: A total of 106 such dyads were assessed on cross-sectional study design. The patients included in the study were above 18 years of age of either sex with a recent (i.e., <6 months) diagnosis of head and neck (lip, tongue, mouth, oropharynx, hypopharynx, pharynx, and larynx) cancer (HNC), not having undergone any surgical intervention for the same and having used SLT for at least 6 months continuously prior to diagnosis of HNC. For each patient, one family member who was aged 18 years or above and lived for at least past 1 year with the patient was included.

RESULT: We found that 60.4% of patients and 6.53% of relatives quit SLT use after the diagnosis of cancer. However, motivation to quit was greater despite continued SLT use, in both patients and relatives. Reasonable number of patients and relatives reported awareness regarding health warnings and long-term consequences of SLT use on cancer. For patients, use of only one form of SLT, presence of 2 or more males in the family using SLT, and presence of another tobacco-related medical disorder in the family were significantly higher in those who quit.

CONCLUSION

The diagnosis of cancer might indeed act as a "teaching moment" for many users but this effect is not extendable on to their relatives.
