Patients filled out the Lubben Social Network Scale (LSNS) at baseline. The Symptom Distress Scale (SDS) and single-item overall quality of life (QOL) Uniscale were assessed at baseline and weekly for 4 weeks.Results: There was no significant difference in overall mean Lubben social support levels by age. Older patients had more relatives they felt close to (85% versus 53% with 5 or more relatives, P = 0.02), heard from more friends monthly (84% versus 53% with 3 or more friends, P = 0.02), less overall symptom distress (P = 0.03), less insomnia (P = 0.003), better concentration (P = 0.005), better outlook (P = 0.01), and less depression (P = 0.005) than younger patients.Conclusions: Younger subjects reported worse symptoms, a smaller social support network, and fewer close friends and relatives than older subjects. Having someone to discuss decisions and seeing friends or relatives often was associated with longer survival. Keywords: social support, Lubben scale, QOL, elderly
