Background
Adjuvant hormonal therapy significantly improves long-term survival of breast cancer patients with hormone receptor-positive disease. Despite the proven clinical efficacy of tamoxifen and aromatase inhibitors, many breast cancer survivors either fail to take the correct dosage at the prescribed frequency (adherence) or discontinue therapy (persistence). This systematic review aims to: 1) determine the prevalence of adherence and persistence to adjuvant hormonal therapy among breast cancer survivors in clinical practice, and 2) identify correlates of adherence and persistence.
Methods
We searched Medline, PubMed, PsycINFO, and CINAHL for studies that measured rates and/or correlates of adherence and/or persistence to adjuvant hormonal therapy. Studies were reviewed in a multi-step process: 1) the lead author screened titles and abstracts of all potentially eligible studies; 2) each coauthor reviewed a random 5% sample of abstracts; and 3) two sets of coauthors each reviewed half of all “maybe” abstracts. Any disagreements were discussed until consensus was reached.
Results
Twenty nine studies met inclusion criteria. Prevalence of adherence ranged from 41–72% and discontinuation (i.e., nonpersistence) ranged from 31–73%, measured at the end of 5 years of treatment. Extremes of age (older or younger), increasing out-of-pocket costs, follow-up care with a general practitioner (vs. oncologist), higher CYP2D6 activity, switching from one form of therapy to another, and treatment side effects were negatively associated with adherence and/or persistence. Taking more medications at baseline, referral to an oncologist, and earlier year at diagnosis were positively associated with adherence and/or persistence.
Conclusions/Implications
Adherence and persistence to adjuvant hormonal therapy among breast cancer survivors is suboptimal. Many of the correlates of adherence and persistence studied to date are not modifiable. Our review reveals a critical need for further research on modifiable factors associated with adherence to adjuvant hormonal therapy, and the development of behavioral interventions to improve adherence in this population.
This review presents a summary of existing knowledge regarding the impact of testicular cancer along four broad domains, including romantic and sexual relationships, body image, and fertility. A total of 37 studies were reviewed. Of note, most research consists of older adult testicular cancer survivors, with very little research attention afforded to adolescent and young adult (AYA) survivorship. Relationship status (i.e., partnered versus unpartnered) appears to play an important role as it relates to adjustment outcomes in testicular cancer survivors. In addition, sexual function (and thereby fertility) and body image are also frequently compromised. Implications regarding a lack of developmentally focused research on AYA testicular cancer survivorship are discussed, along with recommendations for new research.
This study prospectively follows 135 children 5-12 years of age with sexual behavior problems from a randomized trial comparing a 12-session group cognitive-behavioral therapy (CBT) with group play therapy and follows 156 general clinic children with nonsexual behavior problems. Ten-year follow-up data on future juvenile and adult arrests and child welfare perpetration reports were collected. The CBT group had significantly fewer future sex offenses than the play therapy group (2% vs. 10%) and did not differ from the general clinic comparison (3%), supporting the use of short-term CBT. There were no group differences in nonsexual offenses (21%). The findings do not support assumptions about persistent or difficult to modify risk and raise questions about policies and practices founded on this assumption.
Objective
To examine adolescent and young adult (AYA) testicular cancer survivors’ subjective understanding of the impact of cancer in adolescence and young adulthood, with a particular emphasis on romantic and sexual relationships.
Methods
Twenty-one AYA testicular cancer survivors, aged 18 to 34 years, were recruited from outpatient testicular cancer follow-up clinics and completed a semi-structured qualitative interview that assessed the impact of testicular cancer on their romantic and sexual relationships.
Results
Four themes were identified that reflected survivors’ understanding of the impact of cancer in adolescence and young adulthood: (1) embarrassment leads to delays in care-seeking, (2) testicular cancer makes you feel different from others, (3) being different from others makes you damaged goods, and (4) cancer disclosure is difficult.
Conclusions
As these themes represent important components of being in a romantic/sexual relationship, either currently or in the future, AYA testicular cancer survivors would benefit from the development of tailored interventions focused on improving these relevant domains.
