Trends in Health-Related Quality of Life After a Diagnosis of Ductal Carcinoma In Situ

Factors associated with ductal carcinoma in situ (DCIS) treatment patterns and patient-reported outcomes across a large integrated health network

PURPOSE

To examine associations between ductal carcinoma in situ (DCIS) patients' characteristics, treating locations and DCIS treatments received and to pilot assessing quality-of-life (QoL) values among DCIS patients with diverse backgrounds.

METHODS

We performed a retrospective tumor registry review of all patients diagnosed and treated with DCIS from 2018 to 2019 in the UPMC-integrated network throughout central and western Pennsylvania. Demographics, clinical information, and administered treatments were compiled from tumor registry records. We categorized contextual factors such as different hospital setting (academic vs. community), socioeconomic status based on the neighborhood deprivation index (NDI) as well as age and race. QoL survey was administered to DCIS patients with diverse backgrounds via QoL questionnaire breast cancer module 23 and qualitative assessment questions.

RESULTS

A total of 912 patients were reviewed. There were no treatment differences noted for age, race, or NDI. Mastectomy rate was higher in academic sites than community sites (29 vs. 20.4%; p = 0.0045), while hormone therapy (HT) utilization rate was higher in community sites (74 vs. 62%; p = 0.0012). QoL survey response rate was 32%. Only HT side effects negatively affected in QoL scores and there was no significant difference in QoL domains and decision-making process between races, age, NDI, treatment groups, and treatment locations.

CONCLUSION

Our integrated health network did not show chronically noted disparities arising from social determinates of health for DCIS treatments by implementing clinical pathways and system-wide peer review. Also, we demonstrated feasibility in collecting QoL for DCIS women with diverse backgrounds and different socioeconomic statuses.

Ductal carcinoma in situ (DCIS): The importance of patient-reported outcomes (PRO)

Purpose

Patient reported outcomes (PROs) are an optimal method for assessing quality of life (QOL), including physical and psychosocial health. This review summarizes PROs frequently assessed in the setting of a DCIS diagnosis.

Recent findings

Health-related QOL has generally been found to be modestly affected in women with DCIS and similar to women with invasive breast cancer. Several studies reported a substantial negative impact on sexual health and body image, including some differences based on surgery type. Some patients experience pain after treatment, although many physical symptoms resolve. The prevalence of anxiety and depression varied based on assessment timing, with symptoms improving over time. Women with DCIS often overestimate the risks associated both with DCIS and invasive cancer.

Summary

PROs provide critical information regarding the experiences of women following a DCIS diagnosis. Continued inclusion of PROs in clinical trials is warranted, further informing treatment decisions and adequately preparing patients for what to expect following treatment.

Evaluation of Long-Term Satisfaction with Breast Surgery in Patients Treated for Ductal Carcinoma In Situ: A Population-Based Longitudinal Cohort Study

BACKGROUND

Breast-conserving surgery (BCS) and mastectomy have equivalent survival for ductal carcinoma in situ (DCIS), allowing patients to participate in selecting a personalized surgical option; however, this decision-making role can increase patient anxiety. Data evaluating patient satisfaction with their decision to undergo BCS versus mastectomy for the treatment of DCIS are limited.

METHODS

Women with DCIS were enrolled in a population-based, state-wide cohort from 1997 to 2006. Participants were surveyed about their satisfaction with their surgical and reconstruction decisions. Quality-of-life (QoL) evaluations were performed with biennial follow-up surveys though 2016. Multivariable logistic regression modeling examined the relationship between type of surgery and reconstruction with patient satisfaction.

RESULTS

Overall, 1537 women were surveyed, on average, 2.9 years following DCIS diagnosis. Over 90% reported satisfaction with their treatment decision regardless of surgery type. Women who underwent mastectomy with reconstruction were more likely to report lower levels of satisfaction than women who underwent BCS (odds ratio [OR] 2.98, 95% confidence interval [CI] 1.18-7.51, p < 0.01). However, over 80% of women who underwent mastectomies reported satisfaction with their reconstruction decision. Women without reconstruction had the highest levels of satisfaction, while women with implants were more likely to be dissatisfied (implant + autologous: OR 2.77, 95% CI 1.24-6.24; implant alone: OR 4.02, 95% CI 1.947-8.34, p ≤ 0.01). QoL scores were not associated with differences in surgical or reconstruction satisfaction at 5, 10, and 15 years following DCIS diagnosis.

CONCLUSIONS

Women undergoing surgery for DCIS express satisfaction with their treatment decisions. Following mastectomy, most women are satisfied with their reconstruction decision, including women who did not undergo reconstruction.

The association between post-diagnosis health behaviors and long-term quality of life in survivors of ductal carcinoma in situ: a population-based longitudinal cohort study

PURPOSE

Women diagnosed with ductal carcinoma in situ (DCIS) often experience adverse changes in health-related behaviors following diagnosis. The impact of health behaviors on long-term quality of life (QoL) in DCIS survivors has not been investigated.

METHODS

We examined the association of post-diagnosis body mass index (BMI), physical activity, alcohol, and smoking with QoL among 1448 DCIS survivors aged 20-74 enrolled in the population-based Wisconsin in situ Cohort from 1997 to 2006. Health behaviors and QoL were self-reported during biennial post-diagnosis interviews. Physical and mental QoL were measured using the validated SF-36 questionnaire. Generalized linear regression was used to determine the association between behaviors and QoL with adjustment for confounders. Lagged behavior variables were used to predict QoL during follow-up and avoid reverse causation.

RESULTS

Women reported 3,536 QoL observations over an average 7.9 years of follow-up. Women maintaining a healthy BMI had on average a significantly higher summary measure score of physical QoL than obese women (normal versus obese: β = 3.02; 2.18, 3.85). Physical QoL scores were also elevated among those who were physically active (5 + h/week vs. none: β = 1.96; 0.72, 3.20), those consuming at least seven drinks/week of alcohol (vs. none; β = 1.40; 0.39, 2.41), and nonsmokers (vs. current smokers: β = 1.80; 0.89, 2.71). Summary measures of mental QoL were significantly higher among women who were moderately physically active (up to 2 h/week vs. none: β = 1.11; 0.30, 1.92) and nonsmokers (vs. current smokers: β = 1.49;0.45, 2.53).

CONCLUSIONS

Our results demonstrate that maintaining healthy behaviors following DCIS treatment is associated with modest improvements in long-term QoL. These results inform interventions aimed at promoting healthy behaviors and optimizing QoL in DCIS survivors.

Trends in Treatment Patterns and Clinical Outcomes in Young Women Diagnosed With Ductal Carcinoma In Situ

BACKGROUND

Although it is known that the risk of a second breast cancer event among young women diagnosed with ductal carcinoma in situ (DCIS) is higher than in older women, the effect of current treatment options on long-term outcomes in this subgroup of women remains poorly defined. We aimed to evaluate national treatment trends and determine their effect on second breast cancer risk and overall survival among young women diagnosed with DCIS.

MATERIALS AND METHODS

Surveillance, Epidemiology, and End Results data from 1998 to 2011 were used to analyze 3648 DCIS patients younger than age 40 years.

RESULTS

Among all treatment options, breast-conserving surgery (BCS) with radiation therapy (BCS + RT) was the most prevalent (36.1%) followed by mastectomy (MTX) without contralateral prophylactic MTX (CPM; 25.8%), BCS alone (22.2%), and MTX with CPM (15.8%). Risk of a second ipsilateral event was > 5-fold and > 2-fold lower within 2 years and 5 years of initial DCIS diagnosis, respectively, in women who received BCS + RT compared with BCS alone; and overall survival was 3-fold higher in women who received BCS + RT. However, MTX with or without CPM did not show an increase in overall survival compared with BCS + RT. In addition, although the percentage of young women who receive MTX with CPM has increased in recent years, MTX with CPM did not show an increased benefit in survival compared with MTX without CPM.

CONCLUSION

The results of our study suggest that more aggressive treatments do not offer survival benefits over BCS + RT; thus, clinical treatment options in young women with DCIS should be carefully considered.
