TBCRC 057: Survey about willingness to participate in cancer clinical trials during the pandemic.

BACKGROUND: Breast cancer patients experienced heightened anxiety during the pandemic. Also, modifications to clinical trial activities allowing for virtual platforms, local assessments, and greater flexibility were introduced to facilitate participation. We sought to evaluate the association between pandemic-related anxiety and willingness to participate in trials and how pandemic-era modifications to trial activities affect the decision to participate. METHODS: We conducted an online survey from August to September, 2021 of patients with breast cancer assessing pandemic-related anxiety; clinical trials knowledge and attitudes; willingness to participate during and before the pandemic; and how each modification affects the decision to participate. Fisher's exact tests evaluated differences in proportions and two-sample t-tests evaluated differences in means. The association of pandemic-related anxiety with a decline in willingness to participate during compared to prior to the pandemic was modeled using logistic regression. RESULTS: Among 385 respondents who completed the survey, 81% reported moderate-severe pandemic-related anxiety. Mean willingness to participate in a trial was lower during the pandemic than prior [2.97 (SD 1.17) vs. 3.10 (SD 1.09), (p < 0.001)]. Severe anxiety was associated with higher odds of diminished willingness to participate during the pandemic compared to prior (OR 5.07). Each of the modifications, with the exception of opting out of research-only blood tests, were endorsed by >50% of respondents as strategies that would increase their likelihood of deciding to participate. CONCLUSIONS: While pandemic-related anxiety was associated with diminished willingness to participate in trials, the leading reasons for reluctance to consider trial participation were unrelated to the pandemic but included worries about not getting the best treatment, side effects, and delaying care. Patients view trial modifications favorably, supporting continuation of these modifications, as endorsed by the National Cancer Institute and others.

Attempted replication of pharmacogenetic association of variants in PPP1R14C and CCDC148 with aromatase inhibitor-induced musculoskeletal symptoms.

Third-generation aromatase inhibitors (AI) are the standard treatment for patients with hormone receptor positive (HR+) breast cancer. While effective, AI can lead to severe adverse events, including AI-induced musculoskeletal syndrome (AIMSS). Genetic predictors of AIMSS have the potential to personalize AI treatment and improve outcomes. We attempted to replicate results from a previous genome-wide association study that found a lower risk of AIMSS in patients carrying PPP1R14C rs912571 and a higher risk in patients carrying CCDC148 rs79048288. AIMSS data were collected prospectively from patients with HR+ breast cancer prior to starting and after 3 and 6 months of adjuvant AI via the Patient-Reported Outcome Measurement Information System and Functional Assessment of Cancer Therapy-Endocrine Symptom. Germline genotypes for PPP1R14C rs912571 and CCDC148 rs79048288 were tested for a similar association with AIMSS as previously reported via $2 tests. Of the 143 patients with AIMSS and genetics data were included in the analysis. There was no association identified between PPP1R14C rs912571 and AIMSS risk ( P  > 0.05). Patients carrying CCDC148 rs79048288 variant alleles had lower AIMSS incidence in a secondary analysis ( P  = 0.04); however, this was in the opposite direction of the previous finding. The study did not replicate previously reported associations with AIMSS risk for genetic variants in PPP1R14C and CCDC148 and AIMSS risk. Further research is needed to discover and validate genetic predictors of AIMSS that can be used to personalize treatment in patients with HR+ breast cancer.

Feasibility of Symptom Monitoring During the First Year of Endocrine Therapy for Early Breast Cancer Using Patient-Reported Outcomes Collected via Smartphone App.

PURPOSE: Treatment-associated symptoms drive early discontinuation of adjuvant endocrine therapy (ET) for breast cancer. We hypothesized that symptom monitoring with electronic patient-reported outcomes (ePROs) during adjuvant ET will enhance symptom detection, symptom management, and persistence. METHODS: Eligible patients were initiating ET for stage 0-III breast cancer. Participants completed ePRO surveys via smartphone at baseline and 1, 3, 6, and 12 months. Measures included Patient-Reported Outcomes Measurement Information System Anxiety, Depression, Fatigue, and Vaginal Discomfort; plus Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events items assessing joint pain, hot flashes, vaginal dryness, concentration problems, and memory problems. Scores surpassing prespecified thresholds triggered alerts, and recommended symptom management pathways were provided to clinicians. The primary objective was to evaluate feasibility, assessed by survey completion rates, with targets of >65% for the baseline survey and ≥1 follow-up survey during the first 6 months. Secondary objectives included 12-month ET discontinuation rate (target: ≤15%), describing symptoms and evaluating pathway implementation. RESULTS: Among 250 participants, 73.2% completed the baseline survey and 69.6% completed ≥1 follow-up survey during the first 6 months. Thirty-one percent of participants had ≥1 symptom alert at baseline and 74% had ≥1 symptom alert during follow-up. The proportions of participants for whom pathway-concordant symptom management was documented at each time point ranged from 12.8% to 36.6%. Twenty-eight participants (11.2%) discontinued ET by 12 months. CONCLUSION: Symptom monitoring with ePROs during adjuvant ET is feasible. Despite infrequent documentation of pathway-concordant symptom management after symptom alerts, ePROs were associated with favorable short-term ET persistence.

Factors associated with weight gain in pre- and post-menopausal women receiving adjuvant endocrine therapy for breast cancer.

PURPOSE: Weight gain after breast cancer poses health risks. We aimed to identify factors associated with weight gain during adjuvant endocrine therapy (AET). METHODS: Women initiating AET enrolled in a prospective cohort. Participants completed FACT-ES plus PROMIS pain interference, depression, anxiety, fatigue, sleep disturbance and physical function measures at baseline, 3, 6, 12, 24, 36, 48 and 60 months. Treatment-emergent symptoms were defined as changes in scores in the direction indicative of worsening symptoms that exceeded the minimal important difference at 3 and/or 6 months compared to baseline. We used logistic regression to evaluate associations of clinicodemographic features and treatment-emergent symptoms with clinically significant weight gain over 60 months (defined as ≥ 5% compared to baseline) in pre- and post-menopausal participants. RESULTS: Of 309 participants, 99 (32%) were pre-menopausal. The 60 months cumulative incidence of clinically significant weight gain was greater in pre- than post-menopausal participants (67% vs 43%, p < 0.001). Among pre-menopausal participants, treatment-emergent pain interference (OR 2.49), aromatase inhibitor receipt (OR 2.8), mastectomy, (OR 2.06) and White race (OR 7.13) were associated with weight gain. Among post-menopausal participants, treatment-emergent endocrine symptoms (OR 2.86), higher stage (OR 2.25) and White race (OR 2.29) were associated with weight gain while treatment-emergent physical function decline (OR 0.30) was associated with lower likelihood of weight gain. CONCLUSIONS: Weight gain during AET is common, especially for pre-menopausal women. Clinicodemographic features and early treatment-emergent symptoms may identify at risk individuals. IMPLICATIONS FOR CANCER SURVIVORS: Patients at risk for weight gain can be identified early during AET. GOV IDENTIFIER: NCT01937052, registered September 3, 2013.

Adjuvant treatment decisions among adults aged 65 years and older with early-stage hormone receptor positive breast cancer seen in a simple multidisciplinary clinic versus standard consultation.

INTRODUCTION: Randomized studies support de-escalation of adjuvant therapy for a target population of older adults ≥65 years with stage I, estrogen-receptor (ER) positive breast cancer after breast conserving surgery. We sought to evaluate the impact of a simplified multidisciplinary clinic (s-MDC) in this population by comparing treatment patterns and patient perceptions of adjuvant radiation therapy (RT) and hormone therapy (HT) between patients seen in s-MDC vs. standard consultations. MATERIALS AND METHODS: Medical records were retrospectively reviewed for patients in the above target population who underwent surgery between August 2020 and May 2022 at our institution. Two cohorts were included: (1) patients seen in s-MDC, and (2) patients seen in standard clinic separately by medical and radiation oncology (non-s-MDC cohort). The non-s-MDC patients declined, could not attend, and/or were not referred to the s-MDC. Patients in the s-MDC cohort were prospectively administered validated questionnaires to evaluate patient reported data including the Decision Autonomy Preference Scale (DAPS), e-Prognosis, and Medical Maximizing-Minimizing Scale (MMS). Chi square, t-tests, and non-parametric equivalents compared demographics, and logistic regression evaluated RT and HT use and survey score outcomes between cohorts. RESULTS: A total of 127 patients met inclusion criteria, with 33 s-MDC and 94 non-s-MDC patients. There was no difference between the cohorts in age, margin status, histology, grade, or focality. In the s-MDC cohort there were significantly more patients without sentinel lymph node biopsy (71.3% vs 42.4%, p = 0.003) and mean tumor size was smaller (0.69 vs. 0.96 cm, p < 0.003), and Charlson comborbidity index (CCI) was higher (5.21 vs 4.96, p = 0.038). There was no significant difference in receipt of RT (65% s-MDC vs 77% standard; odds ratio [OR] = 0.55, p = 0.189), HT (78% ss-MDC vs 72% standard; OR = 1.36, p = 0.513), or both (50% s-MDC vs 59% standard; OR = 0.7, p = 0.429). The s-MDC cohort was significantly more likely to undergo accelerated (vs. standard hypofractionated) RT (70% vs 39%; OR = 3.59, p = 0.020). In s-MDC patients with completed questionnaires (n = 33), all whose selected "mostly patient (n=6)" based decision making by DAPS chose RT while all "mostly doctor (n=1)" chose no RT. Based on e-Prognosis, there were lower odds of RT for increasing Schonberg score/ higher 10 yr mortality risk (OR 0.600, p = 0.048). MMS score ≥ 40 ("maximizer") was strongly linked with the use of RT (OR 18.57, p = 0.011). DISCUSSION: For adults ≥65 years with early stage, ER positive breast cancer, s-MDC participation was not significantly associated with lower use of adjuvant RT or HT versus standard consultation but was significantly associated with shorter RT courses. DAPS and MMS results indicate that patient treatment preference may be predictable, highlighting an opportunity to tailor consultation discussions and recommendations based on intrinsic patient preferences and individual goals.

Factors associated with worsening sexual function during adjuvant endocrine therapy in a prospective clinic-based cohort of women with early-stage breast cancer.

PURPOSE: Sexual function problems are common but under-reported among women receiving adjuvant endocrine therapy for breast cancer. Worsening scores on patient-reported outcomes (PROs) may identify those at risk for sexual function problems during treatment. We performed a secondary analysis of prospectively collected PROs in women receiving adjuvant endocrine therapy to identify factors associated with worsening sexual function. METHODS: Women with stage 0-III breast cancer initiating adjuvant endocrine therapy participating in a prospective cohort completed PROs at baseline, 3, 6, 12, 24, 36, 48, and 60 months. Sexual function was evaluated by the MOS-SP measure. Other measures included PROMIS pain interference, fatigue, depression, anxiety, physical function, and sleep disturbance and the Endocrine Symptom Subscale of the FACT-ES. We evaluated associations between score worsening of at least the minimal important difference (MID) in PROMIS T-scores (4 points) and FACT-ES scores (5 points) with score worsening of at least the MID in MOS-SP scores (8 points) using logistic regression. RESULTS: Among 300 participants, 45.7% experienced ≥ 8-point worsening of MOS-SP score at any time point compared to baseline. Worsening endocrine symptoms (OR 1.34, 95% CI 1.22-1.49, p < 0.001), worsening physical function (OR 1.09, 95% CI 1.00-1.18, p = 0.06), and prior mastectomy (OR 1.45, 95% CI 0.94-2.23, p = 0.09) were associated with MOS-SP score worsening by at least the MID. CONCLUSION: Worsening endocrine symptoms and physical function identified on PROs are associated with worsening sexual function during adjuvant endocrine therapy. Routine assessment of these domains with PROs may identify women at risk for sexual function problems. TRIAL REGISTRATION NUMBER: NCT01937052; Date of Registration: 09/09/2013.

Association of treatment-emergent symptoms identified by patient-reported outcomes with adjuvant endocrine therapy discontinuation.

Many patients discontinue endocrine therapy for breast cancer due to intolerance. Identification of patients at risk for discontinuation is challenging. The minimal important difference (MID) is the smallest change in a score on a patient-reported outcome (PRO) that is clinically significant. We evaluated the association between treatment-emergent symptoms detected by worsening PRO scores in units equal to the MID with discontinuation. We enrolled females with stage 0-III breast cancer initiating endocrine therapy in a prospective cohort. Participants completed PROs at baseline, 3, 6, 12, 24, 36, 48, and 60 months. Measures included PROMIS pain interference, fatigue, depression, anxiety, physical function, and sleep disturbance; Endocrine Subscale of the FACT-ES; and MOS-Sexual Problems (MOS-SP). We evaluated associations between continuous PRO scores in units corresponding to MIDs (PROMIS: 4-points; FACT-ES: 5-points; MOS-SP: 8-points) with time to endocrine therapy discontinuation using Cox proportional hazards models. Among 321 participants, 140 (43.6%) initiated tamoxifen and 181 (56.4%) initiated aromatase inhibitor (AI). The cumulative probability of discontinuation was 23% (95% CI 18-27%) at 48 months. For every 5- and 4-point worsening in endocrine symptoms and sleep disturbance respectively, participants were 13 and 14% more likely to discontinue endocrine therapy respectively (endocrine symptoms HR 1.13, 95% CI 1.02-1.25, p = 0.02; sleep disturbance HR 1.14, 95% CI 1.01-1.29, p = 0.03). AI treatment was associated with greater likelihood of discontinuation than tamoxifen. Treatment-emergent endocrine symptoms and sleep disturbance are associated with endocrine therapy discontinuation. Monitoring for worsening scores meeting or exceeding the MID on PROs may identify patients at risk for discontinuation.

Late Recurrence Following Early Breast Cancer.

The Oncology Grand Rounds series is designed to place original reports published in the Journal into clinical context. A case presentation is followed by a description of diagnostic and management challenges, a review of the relevant literature, and a summary of the authors' suggested management approaches. The goal of this series is to help readers better understand how to apply the results of key studies, including those published in the Journal of Clinical Oncology, to patients seen in their own clinical practice.

A PRO-cision medicine intervention to personalize cancer care using patient-reported outcomes: intervention development and feasibility-testing.

PURPOSE: PRO-cision medicine refers to personalizing care using patient-reported outcomes (PROs). We developed and feasibility-tested a PRO-cision Medicine remote PRO monitoring intervention designed to identify symptoms and reduce the frequency of routine in-person visits. METHODS: We conducted focus groups and one-on-one interviews with metastatic breast (n = 15) and prostate (n = 15) cancer patients and clinicians (n = 10) to elicit their perspectives on a PRO-cision Medicine intervention's design, value, and concerns. We then feasibility-tested the intervention in 24 patients with metastatic breast cancer over 6-months. We obtained feedback via end-of-study surveys (patients) and interviews (clinicians). RESULTS: Focus group and interview participants reported that remote PRO symptom reporting could alert clinicians to issues and avoid unneeded/unwanted visits. However, some patients did not perceive avoiding visits as beneficial. Clinicians were concerned about workflow. In the feasibility-test, 24/236 screened patients (10%) enrolled. Many patients were already being seen less frequently than monthly (n = 97) or clinicians did not feel comfortable seeing them less frequently than monthly (n = 31). Over the 6-month study, there were 75 total alerts from 392 PRO symptom assessments (average 0.19 alert/assessment). Patients had an average of 4 in-person visits (vs. expected 6.5 without the intervention). Patients (n = 19/24) reported high support on the end-of-study survey, with more than 80% agreeing with positive statements about the intervention. Clinician end-of-study interviews (n = 11/14) suggested that PRO symptom monitoring be added to clinic visits, rather than replacing them, and noted the increasing role of telemedicine. CONCLUSIONS: Future research should explore combining remote PRO symptom monitoring with telemedicine and in-person visits.

Examining the association among fear of COVID-19, psychological distress, and delays in cancer care.

BACKGROUND: Given the high risk of COVID-19 mortality, patients with cancer may be vulnerable to fear of COVID-19, adverse psychological outcomes, and health care delays. METHODS: This longitudinal study surveyed the pandemic's impact on patients with cancer (N= 1529) receiving Patient Advocate Foundation services during early and later pandemic. Generalized estimating equation with repeated measures was conducted to assess the effect of COVID-19 on psychological distress. Logistic regression with repeated measures was used to assess the effect of COVID-19 on any delays in accessing health care (e.g., specialty care doctors, laboratory, or diagnostic testing, etc.). RESULTS: Among 1199 respondents, 94% considered themselves high risk for COVID-19. Respondents with more fear of COVID-19 had a higher mean psychological distress score (10.21; 95% confidence intervals [CI] 9.38-11.03) compared to respondents with less fear (7.55; 95% CI 6.75-8.36). Additionally, 47% reported delaying care. Respondents with more fear of COVID-19 had higher percentages of delayed care than those with less (56; 95% CI 39%-72% vs. 44%; 95% CI 28%-61%). These relationships persisted throughout the pandemic. For respondents with a COVID-19 diagnosis in their household (n = 116), distress scores were similar despite higher delays in care (58% vs. 27%) than those without COVID-19. CONCLUSIONS: Fear of COVID-19 is linked to psychological distress and delays in care among patients with cancer. Furthermore, those who are personally impacted see exacerbated cancer care delays. Timely psychosocial support and health care coordination are critical to meet increased care needs of patients with cancer during the COVID-19 pandemic.

Further Evidence That OPG rs2073618 Is Associated With Increased Risk of Musculoskeletal Symptoms in Patients Receiving Aromatase Inhibitors for Early Breast Cancer.

BACKGROUND: Aromatase inhibitors (AI) reduce recurrence and death in patients with early-stage hormone receptor-positive (HR +) breast cancer. Treatment-related toxicities, including AI-induced musculoskeletal symptoms (AIMSS), are common and may lead to early AI discontinuation. The objective of this study was to replicate previously reported associations for candidate germline genetic polymorphisms with AIMSS. METHODS: Women with stage 0-III HR + breast cancer initiating adjuvant AI were enrolled in a prospective clinic-based observational cohort. AIMSS were assessed by patient-reported outcomes (PRO) including the PROMIS pain interference and physical function measures plus the FACT-ES joint pain question at baseline and after 3 and 6 months. For the primary analysis, AIMSS were defined as ≥ 4-point increase in the pain interference T-score from baseline. Secondary AIMSS endpoints were defined as ≥ 4-point decrease in the physical function T-score from baseline and as ≥ 1-point increase on the FACT-ES joint pain question from baseline. The primary hypothesis was that TCL1A rs11849538 would be associated with AIMSS. Twelve other germline variants in CYP19A1, VDR, PIRC66, OPG, ESR1, CYP27B1, CYP17A1, and RANKL were also analyzed assuming a dominant genetic effect and prespecified direction of effect on AIMSS using univariate logistic regression with an unadjusted α = 0.05. Significant univariate associations in the expected direction were adjusted for age, race, body mass index (BMI), prior taxane, and the type of AI using multivariable logistic regression. RESULTS: A total of 143 participants with PRO and genetic data were included in this analysis, most of whom were treated with anastrozole (78%) or letrozole (20%). On primary analysis, participants carrying TCL1A rs11849538 were not more likely to develop AIMSS (odds ratio = 1.29, 95% confidence interval: 0.55-3.07, p = 0.56). In the statistically uncorrected secondary analysis, OPG rs2073618 was associated with AIMSS defined by worsening on the FACT-ES joint pain question (OR = 3.33, p = 0.004), and this association maintained significance after covariate adjustment (OR = 3.98, p = 0.003). CONCLUSION: Carriers of OPG rs2073618 may be at increased risk of AIMSS. If confirmed in other cohorts, OPG genotyping can be used to identify individuals with HR + early breast cancer in whom alternate endocrine therapy or interventions to enhance symptom detection and implement strategies to reduce musculoskeletal symptoms may be needed.

Interventions for multidimensional aspects of breast cancer-related fatigue: a meta-analytic review.

PURPOSE: This meta-analysis sought to determine whether exercise, psychological, or alternative forms of interventions differentially improve cognitive, physical, and general dimensions of cancer-related fatigue (CRF) in women with a history of breast cancer. METHODS: Databases (PubMed, PsychINFO, EMBASE, and Cochrane Library) were systematically reviewed from inception through March 2019, with data extracted from randomized controlled trials of fatigue interventions using multidimensional CRF outcome measures. Two authors independently assessed methodological quality using the Cochrane Collaboration's risk of bias tool. Analyses were performed with Comprehensive Meta-Analysis (v.3). RESULTS: A total of 471 studies were assessed, of which 11 studies with 12 sets of data involving 1067 patients were included. Across intervention types, small to moderate improvements were observed for cognitive (g = - 0.38), physical (g = - 0.46), and general (g = - 0.45) CRF (p values < 0.01). Exercise produced moderate benefit for cognitive (g = - 0.44), physical (g = - 0.48), and general (g = - 0.49) CRF (p values < 0.01) whereas psychotherapy and disparate forms of alterative interventions were not effective (p values > 0.45). However, a large effect size was observed for a single trial of acupressure across all three CRF dimensions (p < 0.05). CONCLUSIONS: Exercise improved both cognitive and physical aspects of CRF. Further studies should determine the most effective forms, duration, intensity, and methods of supporting exercise in breast cancer patients. Further investigation of acupressure as an intervention for CRF should also be considered.

Therapeutic Targeting of Minimal Residual Disease to Prevent Late Recurrence in Hormone-Receptor Positive Breast Cancer: Challenges and New Approaches.

While the majority of breast cancers are diagnosed at a curable stage, approximately 20% of women will experience recurrence at a distant site during their lifetime. These metastatic recurrences are incurable with current therapeutic approaches. Over the past decade, the biologic mechanisms underlying these recurrences have been elucidated, establishing the existence of minimal residual disease in the form of circulating micrometastases and dormant disease, primarily in the bone marrow. Numerous technologies are now available to detect minimal residual disease (MRD) after breast cancer treatment, but it is yet unknown how to best target and eradicate these cells, and whether clearance of detectable disease prior to the formation of overt metastases can prevent ultimate progression and death. Clinical trials to test this hypothesis are challenging due to the rare nature of MRD in the blood and bone marrow, resulting in the need to screen a large number of survivors to identify those for study. Use of prognostic molecular tools may be able to direct screening to those patients most likely to harbor MRD, but the relationship between these predictors and MRD detection is as yet undefined. Further challenges include the lack of a definitive assay for MRD with established clinical utility, difficulty in selecting potential interventions due to limitations in understanding the biology of MRD, and the emotional impact of detecting MRD in patients who have completed definitive treatment and have no evidence of overt metastatic disease. This review provides a roadmap for tackling these challenges in the design and implementation of interventional clinical trials aimed at eliminating MRD and ultimately preventing metastatic disease to improve survival from this disease, with a specific focus on late recurrences in ER+ breast cancer.

Breast Cancer, Version 3.2020, NCCN Clinical Practice Guidelines in Oncology.

Several new systemic therapy options have become available for patients with metastatic breast cancer, which have led to improvements in survival. In addition to patient and clinical factors, the treatment selection primarily depends on the tumor biology (hormone-receptor status and HER2-status). The NCCN Guidelines specific to the workup and treatment of patients with recurrent/stage IV breast cancer are discussed in this article.

Clinico-pathologic features, treatment and outcomes of breast cancer during pregnancy or the post-partum period.

PURPOSE: Breast cancer during pregnancy (BC-P) or the first year post-partum (BC-PP) is rare and whether it differs from breast cancer (BC) in young women not associated with pregnancy is uncertain. METHODS: We queried our institutional database for BC-P and BC-PP cases and matched controls with BC not associated with pregnancy diagnosed between January 1, 1985 and December 31, 2013. We performed two parallel retrospective cohort studies evaluating clinico-pathologic features, treatment and outcomes for BC-P and BC-PP cases compared to their controls. RESULTS: In our population of 65 BC-P cases, 135 controls for BC-P cases, 75 BC-PP cases and 145 controls for BC-PP cases, high grade and estrogen receptor-negativity were more frequent in both case groups than their controls. Among those with stage I-III BC, patterns of local therapy were similar for both case groups and their controls, with the majority undergoing surgery and radiation. Over three-fourths of those with stage I-III BC received chemotherapy. BC-P cases tolerated chemotherapy well, with the majority receiving doxorubicin/cyclophosphamide every 3 weeks. On multivariate analyses of those with stage I-III BC, BC-P cases had non-significantly higher hazards of recurrence and death compared to their controls, while BC-PP cases had non-significantly lower hazards of recurrence and death compared to their controls. CONCLUSION: BC-P and BC-PP were associated with adverse clinic-pathologic features in our population. However, we did not observe inferior outcomes for BC-P or BC-PP compared to controls, likely due to receipt of aggressive multi-modality therapy.

Patient-reported outcomes in the Translational Breast Cancer Research Consortium.

Members of the Translational Breast Cancer Research Consortium conducted an expert-driven literature review to identify a list of domains and to evaluate potential measures of these domains for inclusion in a list of preferred measures. Measures were included if they were easily available, free of charge, and had acceptable psychometrics based on published peer-reviewed analyses. A total of 22 domains and 52 measures were identified during the selection process. Taken together, these measures form a reliable and validated list of measurement tools that are easily available and used in multiple cancer trials to assess patient-reported outcomes in relevant patients.

Advances in Fertility Preservation for Young Women With Cancer.

Female patients of reproductive age with cancer often require treatment that can compromise their future fertility. Treatment-related infertility is an important cancer survivorship issue and is associated with depression and diminished quality of life. Recent advances in reproductive health care provide the opportunity to preserve fertility prior to the initiation of cancer therapy. Clinical guidelines recommend that oncology providers counsel patients about the risk of treatment-related infertility and fertility preservation options, and that they refer those who are interested in fertility preservation to fertility specialists. Guidelines endorse the use of assisted reproductive techniques (ART) provided by reproductive endocrinologists to preserve fertility in young female patients with cancer. In addition, ovarian suppression with gonadotropin-releasing hormone (GnRH) agonists may be considered for ovarian protection during chemotherapy. This article reviews currently available and emerging ART for fertility preservation in female patients of reproductive age with cancer and current data supporting the use of ovarian suppression for ovarian protection during chemotherapy in this population. We also review the uptake of fertility services and discuss barriers to fertility preservation in female patients of reproductive age with cancer.
