BackgroundThe diagnosis and treatment of breast cancer can have profound effects on a young woman's family planning and fertility, particularly among women with hormone receptor–positive breast cancer.MethodsThe Young Women's Breast Cancer Study was a multicenter cohort of women aged 40 years or younger and newly diagnosed with breast cancer from 2006 to 2016. Surveys included assessments of fertility concerns, endocrine therapy (ET) preferences, and use. Characteristics were compared between women who reported that fertility concerns affected ET decisions and those who did not. Logistic regression was used to identify factors associated with having an ET decision affected by fertility concerns.ResultsOf 643 eligible women with hormone receptor–positive, stage I to III breast cancer, one‐third (213 of 643) indicated that fertility concerns affected ET decisions. In a multivariable analysis, only parity at diagnosis was significantly associated with fertility concerns affecting ET decisions (odds ratio for nulliparous vs ≥2 children, 6.96; 95% confidence interval, 4.09‐11.83; odds ratio for 1 vs ≥2 children, 5.30; 95% confidence interval, 3.03‐9.87). Noninitiation/nonpersistence was higher among women with fertility concerns versus those without fertility concerns (40% vs 20%; P < .0001). Among women with fertility‐related ET concerns, 7% (15 of 213) did not initiate ET, and 33% (70 of 213) were nonpersistent over 5 years of follow‐up. Of these women, 66% (56 of 85) reported 1 or more pregnancies or pregnancy attempts; 27% (15 of 56) had resumed ET at the last available follow‐up through 5 years.ConclusionsConcern about fertility is a contributor to adjuvant ET decisions among a substantial proportion of young breast cancer survivors. Ensuring family planning is addressed in the setting of ET recommendations should be a priority throughout the cancer care continuum.

Abstract BackgroundCancer diagnosis and early treatment may have wide-ranging consequences for a woman’spartner (ie. spouse or significant other). In general, younger caregivers have been found to havegreater unmet needs and higher levels of distress compared to those who are older. To date,there is little known about the unmet needs and experiences of partners who care for youngwomen with breast cancer during active treatment.Trial Design: Cross-sectional survey of partners of young women with breast cancer.Eligibility Criteria: The current analysis focuses on a subset of respondent partners of womenwith breast cancer participating in the Young Womens Breast Cancer Study (NCT01468246)who met the following criteria: diagnosed at age &lt; 40 years; time since diagnosis &lt;12 months;and/or Stage IV disease (at diagnosis or in metastatic setting); and/or local recurrent disease&lt; 12 months.Specific Aims: To explore the experience of partners of women in active treatment or havingvery recently completed treatment for breast cancer.Statistical Methods: We employed descriptive statistics to present sample characteristics,including means or medians for continuous variables and proportions for categorical variables.We assessed partners’ responses re: sociodemographics, perceived social support (MOS-Social Support Survey, Cancer Perceived Agents of Social Support), quality of life (QOL)(Caregiver QOL Index-Cancer), coping (Brief COPE), perceived financial security, perceivedparenting concerns (Parenting Concerns Questionnaire), anxiety and depression symptoms(Hospital Anxiety and Depression Scale), sexual satisfaction (Global Measure of SexualSatisfaction), posttraumatic growth (Posttraumatic Growth Inventory-Short Form), and an open-ended question to explore their experiences and needs.Accrual: 25 participants were included.Results: All partners were male (25/25; 100%), and most were white (n=23/25; 92%), workingfull-time (n=21/25; 91%); and college educated (n=19/25; 86%). Eighteen partners (n=18/25;72%) were parenting children &lt;18 years old and 40% (n=10/25) were partnered with womenwith Stage 4 breast cancer. At the time of the survey, the median age of partners was 44 years(range, 28-69) and of patients was 38 years (range, 25-40). Many partners (57%) reportedsymptoms of anxiety (&gt;8 on the HADS anxiety subscale), fewer (22%) were categorized ashaving symptoms of depression (&gt;8 on the HADS depression subscale). Additionally, 39%reported not being sexually active; 41% reported maladaptive coping; 30% reported financialstrain;30% reported relationship strain. Reported caregiver QOL ranged from 22-116, with amean score of 52.5 (SD, 23.9), similar to population norms, with higher scores indicating lowerquality of life. Parenting concerns scores were generally low indicating less concern, with arange of 12-35, and mean of 20.5 (SD, 7.6). Post-traumatic growth ranged from 4-33, with amean score of 20.7 (SD, 7.4), with higher scores indicating greater personal growthexperienced. 44% (11/25) responded to the open-ended experiences and needs question.Common responses included feeling a lack of support, need for tailored and titrated information,and desire to connect with other men who faced similar experiences. Partners also reportedtheir struggles with uncertainty about the future. Discussion: A subset of partners of young women in active treatment for breast cancerexpressed concerns related to relationship strain, sexuality, need for support, and finances.Future work designed to meet the needs of partners of breast cancer patients includinginformational and psychosocial supports may benefit them and the patients as they manage theprocess of ongoing treatment and challenges about the future.

BackgroundMany young women with newly diagnosed breast cancer are interested in future pregnancies. Prospective data regarding fertility interest and reproductive patterns after diagnosis are needed to counsel patients.MethodsThe Young Women's Breast Cancer Study is a multicenter, prospective cohort of women who were diagnosed with breast cancer at age ≤40 years between 2006 and 2016. Women complete surveys at baseline, every 6 months for 3 years, then annually. Here, the authors describe fertility interest and pregnancies within 5 years of diagnosis for women with stage 0 through III breast cancer.ResultsOf 1026 eligible participants, 368 (36%) reported interest in future biologic children at least once within 5 years after diagnosis, including 16% at 5 years after diagnosis. Among 130 women who attempted to become pregnant, 90 (69.2%) conceived; and, among 896 women who did not attempt to conceive, 18 (2.0%) became pregnant, with a total of 152 pregnancies resulting in 91 live births. Factors associated with pregnancy included younger versus older age at diagnosis (aged ≤30 vs 36‐40 years: odds ratio [OR], 6.63; 95% CI, 3.18‐13.83; P < .0001; aged 31‐35 vs 36‐40 years: OR, 5.86; 95% CI, 3.37‐10.17; P < .0001) and being nulliparous versus parous (OR, 2.66; 95% CI, 1.56‐4.53; P = .001). The receipt of endocrine therapy versus no endocrine therapy (OR, 0.35; 95% CI, 0.20‐0.59; P = .001) was inversely associated with pregnancy.ConclusionsMany women remain interested in future fertility in the 4 years after a breast cancer diagnosis, indicating that longitudinal fertility discussions are needed. Although a minority of those interested in having children attempted to become pregnant in the first 5 years, most who attempted to conceive did so and had live births.

AbstractObjectiveYoung breast cancer patients experience greater psychosocial distress compared with older patients, which raises concern for their risk of posttraumatic stress disorder (PTSD). We sought to characterize the prevalence of clinically significant symptoms of PTSD and associated factors among breast cancer survivors diagnosed at a young age.MethodsThe Young Women's Breast Cancer Study, an ongoing prospective cohort study, enrolled 1302 women diagnosed with breast cancer at age ≤ 40 between 2006 and 2016. Participants complete serial surveys, and we obtained additional information from medical record review. Socio‐demographics, anxiety and depression, social support, and psychiatric co‐morbidities and medications were assessed at study baseline (median, 5 months post‐diagnosis). We defined a participant as having clinically significant posttraumatic stress symptoms (PTSS) by scoring ≥50 on the PTSD Checklist‐Specific Version, administered on the 30‐month survey.ResultsAmong 700 women with stage 1‐3 disease, the prevalence of PTSS was 6.3% (95%CI = 4.5‐8.1). In multivariable analyses, PTSS was significantly associated with anxiety (OR 12.43, 95%CI = 5.81‐26.59, P < .0001) and stage 2 vs 1 disease (OR 2.26, 95%CI = 1.04‐4.93, P = .04). PTSS was inversely associated with having a college degree (OR 0.29, 95%CI = 0.13‐0.62, P = .002) and greater social support (OR 0.44, 95%CI = 0.21‐0.94, P = .03).ConclusionsWe found similar rates of cancer‐related PTSS in breast cancer survivors diagnosed at a young age compared with the general breast cancer population despite their well‐documented increased risk of overall distress. Nevertheless, factors associated with posttraumatic stress should be considered at diagnosis and in survivorship to identify young patients who may benefit from psychosocial resources.

514 Background: The 21- gene Breast Recurrence Score predicts benefit from adjuvant chemotherapy in estrogen receptor positive (ER+), HER-2 negative (-) breast cancer (BC). We aimed to examine whether the 21-gene assay predicts response to neoadjuvant chemotherapy (NAC). Methods: We identified patients with stage I-III ER+/HER2− BC treated with NAC from the Young Women's Breast Cancer Study, a prospective cohort of women diagnosed with BC at age ≤ 40 years. The 21-gene assay was performed on tumor specimens removed prior to NAC either as part of clinical care or retrospectively for research. Pathologic complete response (pCR) was defined as no residual invasive tumor (ypT0/is ypN0). The relationship between Recurrence Score result (RS) and pCR was evaluated using logistic regression modeling. Results: 76 women in the cohort had undergone NAC for ER+, HER2- BC and were eligible for this analysis: 5 had undergone clinical 21-gene assay testing, 71 had banked specimens retrospectively tested. Median age at diagnosis was 36.7 (24.3-40). Most tumors were of ductal histology (78%), high grade (51%), progesterone receptor (PgR) positive (86%), ≥T2 (88%), clinically node positive (74%), and anthracycline and taxane containing protocols were administered in 86% of cases. RS ranged between 5-75 with 50% > 25 and only 4 < 11. Mean RS was significantly higher among tumors achieving pCR vs. non-pCR response (51.9 vs. 26.6, pwilcoxon= 0.0005). pCR rate in patients with RS > 25 was 21% (8/38) vs. 5% in patients with RS < 25 (2/38), with both pCRs in the <25 group in patients with RS 21-25. In univariable analysis, PgR negativity (odds ratio (OR) 5.62, 95% confidence interval (CI) 1.27-24.89, p = 0.02), high grade (OR 9.03, 95%CI 1.07-76.32, p = 0.04) and higher RS as a continuous variable (OR 1.08, 95%CI 1.04-1.13, p = 0.0003) were associated with a greater likelihood of pCR. In multivariable analysis only RS remained significantly associated with pCR (OR: 1.07, 95%CI 1.01-1.12, p = 0.01): a 7% increase in the odds of pCR for every 1-point increase in RS. Conclusions: In young women with ER+, HER2- BC who received NAC, higher pretreatment RS was associated with an increased likelihood of pCR. Genomic expression profiling assays may have a role in decision-making in young women in need of neoadjuvant therapy. For women with low likelihood of benefiting from NAC, alternative approaches are clearly warranted. Given the demonstrated efficacy of neoadjuvant endocrine therapy in post-menopausal women, further evaluation in young women should be pursued.

Abstract Background: Fear of cancer recurrence (FCR) is prevalent among breast cancer survivors and more intense in younger women. Given that FCR is a powerful determinant of quality of life and is associated with healthcare utilization, identifying who may be at risk for experiencing elevated FCR without resolution can inform the timing and targeting of interventions. Methods: Participants included women diagnosed (dx’d) at age ≤40 enrolled in the Young Women’s Breast Cancer Study, a multi-site prospective cohort surveyed at baseline and regularly in follow-up. Surveys include the 3-item Lasry Fear of Recurrence Index which measures the degree of concern about recurrence and current health using 4-point Likert response options that provide a score ranging from 3-12; higher scores indicate greater concern. Group-based trajectory modeling was used to classify distinct FCR patterns from baseline (median of 5 months from dx) through 3 years post-dx. Multinomial logistic regression was used to identify the associated patient (socio-demographics and BRCA status), disease (stage, ER/PR/HER2) and treatment (surgery, chemotherapy) characteristics associated with each trajectory. Variables significant at p&lt;0.05 in univariable models were entered into the final multivariable model. Results: 965 women with Stages 0-III breast cancer were included in the analysis, with a median age at dx of 37. Participants were predominantly non-Hispanic White (85%), partnered (76%) and had completed college (84%). There was a significant decrease in median FCR scores from baseline to year 3 (9 vs. 8, Wilcoxon signed-rank test P&lt;0.01). Five FCR trajectories (Table) were identified: 1) 10.5% of participants reported low/stable FCR from baseline over follow-up; 2) 33.1% had moderate FCR that improved over time; 3) 5.5% had moderate FCR scores at baseline that worsened over time; 4) 30% had high FCR scores at baseline that improved over time; 5) 20.8% had high FCR at baseline that remained high at all time points. In the fully adjusted multinomial model, younger age at dx and Stage 3 and 2 (vs. 1) disease were associated with higher odds of being in the high/stable trajectory. Having a lumpectomy (vs. mastectomy) was associated with higher odds of being in a high/stable as well as moderate/improving trajectory while White (vs. non-White) women had higher odds of being in a trajectory of improving FCR. Receipt of chemotherapy and financial discomfort were significantly associated with assignment to specific FCR trajectories in univariate analyses, however did not remain significant in the adjusted model. Being partnered, BRCA mutation status, and ER/PR/HER2 status were not significantly associated with any FCR trajectory classification in univariate or multivariate analyses. Conclusion: While FCR improves over time for many young women with breast cancer, a substantial minority (26%) had FCR that was severe and did not improve or worsened over time. Younger women with higher stage disease who are at risk for high levels of unresolved FCR may benefit from intervention including early referral to mental health professionals. Ongoing monitoring of women at risk for developing FCR following active treatment is warranted.

11574 Background: Weight gain after cancer diagnosis is common in cancer survivors and has been linked to increased treatment toxicity, poor quality of life, and increased risk of second cancers and overall mortality. Young breast cancer (BC) survivors may be especially susceptible to weight changes given the impact of treatments such as chemotherapy and hormonal therapy on menopausal status. Methods: We identified women with Stage 0-III breast cancer diagnosed at ≤40 years (y) between 2006-2016 from a multi-center prospective cohort study. Clinical data including self-reported pre-diagnosis and follow-up weights were obtained using baseline and follow-up patient surveys. Participants missing baseline weight, pregnant at diagnosis/within 1y of diagnosis or with BC recurrence within 1y were excluded; those pregnant or with BC recurrence between 1-3y from diagnosis were excluded from the 3y analysis. Menopausal status at baseline and treatment-related amenorrhea (TRA) in follow-up were defined by self-reported last menstrual period. Factors associated with weight gain (>5%) were evaluated using univariate two-sided Fisher's exact test. Results: At baseline, 1y and 3y post diagnosis, 956, 899 and 687 women were eligible for analysis respectively. Median age at diagnosis was 37y (17 - 40), 65% received endocrine therapy and 74% chemotherapy. Premenopausal status was verified in 94% at baseline. Mean BMI at baseline was 24.4 (SD 5.3) kg/m2; 20% (187/956) were overweight and 12% (116/956) obese. At 1y and 3y, mean BMI increased modestly to 24.7 (SD 5.6) and 24.9 (SD 5.2), respectively with weight gain (>5%) observed in 18% (164/899) and 13% (87/687) respectively. 37% (300/804) and 32% (196/615) of eligible premenopausal subjects experienced TRA at 1y and 3y, respectively. Receipt of chemotherapy, receipt of endocrine therapy and TRA were not associated with weight gain at any timepoint. Conclusions: In this large prospective cohort of young BC survivors, mean BMI increased only modestly over time. Self-reported weight gain was not associated with treatment and not exacerbated by TRA. Further analysis to understand the effects of physical activity and other predictors of weight gain in this population are ongoing.

PURPOSE The 21-gene recurrence score (RS) assay is prognostic among women with early-stage estrogen receptor–positive (ER+) and human epidermal growth factor receptor 2–negative (HER2−) breast cancer and is used to inform recommendations for chemotherapy. Women ≤ 40 years of age represent a minority of patients studied using gene expression profiles. METHODS The Young Women's Breast Cancer Study is a prospective cohort of women diagnosed with breast cancer at age ≤ 40 years and enrolled patients between 2006 and 2016 (N = 1,302). We identified patients with stage I-III ER+/HER2− breast cancer. The RS assay was performed on banked specimens for patients who had not been tested clinically. Distant recurrence-free survival (DRFS) was assessed by TAILORx and traditional RS risk groups among patients with axillary node–negative (N0) and limited node–positive (N1) breast cancer. RESULTS Among eligible women (N = 577), 189 (33%) had undergone RS testing, and 320 (56%) had banked specimens sufficient for testing. Median follow-up was 6.0 years. Median age at diagnosis was 37.2 years; 300 of 509 patients (59%) had N0 breast cancer, of whom 195 (65%) had an RS of 11-25 and fewer than half (86 of 195; 44%) received chemotherapy. Six-year DRFS rates were 94.4% and 92.3% (RS < 11), 96.9% and 85.2% (RS 11-25), and 85.1% and 71.3% (RS ≥ 26) among women with N0 and N1 disease, respectively. CONCLUSION The RS assay is prognostic among young women with node-negative and limited node-positive breast cancer, representing a valuable tool for risk stratification. Disease outcomes with a median follow-up of 6 years among young women with N0 disease and an RS of 0-25, a minority of whom received chemotherapy, and node-positive disease with an RS < 11 were very good, whereas those with N0 disease and an RS ≥ 26 or N1 disease with an RS ≥ 11 experienced substantial risk of early distant recurrence.
