Depression and Anxiety Among English- and Spanish-Speaking Patients With Breast Cancer Receiving Radiation Therapy

PURPOSE

An estimated 30% and 40% of patients with breast cancer experience depression and anxiety, respectively. However, distress experienced by patients with breast cancer receiving radiation therapy may vary among patients and vary at different time points. This study sought to describe the changes in levels of depression and anxiety experienced by English- and Spanish-speaking patients throughout a course of radiation therapy for breast cancer, along with the effect of different variables to better understand potential gaps.

METHODS AND MATERIALS

Eligibility criteria included English- and Spanish-speaking females, aged 18 or older, undergoing radiation therapy treatment for breast cancer at 2 institutions. Pre- and posttreatment surveys were completed before and after delivery of radiation therapy. Sociodemographic characteristics collected included race, ethnicity, marital status, education level, longest residency location, religion, housing, and food insecurity. The survey ended with the standardized PHQ-4 questionnaire to assess anxiety and depression. Results were analyzed using the analysis of covariance procedure.

RESULTS

A total of 160 participants completed pre- and posttreatment surveys, with an initial response rate of 100% (169 patients), though 9 were lost to follow-up. Most of the participants were nonwhite (50%), primarily married (42.5%), and had a high school or associate's level education (46.9%). The total baseline distress mean (BDM) was 2.96 and the final distress mean was 2.78. English-speaking patients comprised 82.5% (n = 132) of the sample and had a BDM of 2.91 with an adjusted change mean decrease of 0.45. Spanish-speaking patients comprised 17.5% (n = 28) of the sample, with a baseline distress mean of 3.21 and an adjusted change mean increase of 1.03 (P = .002). Housing (P = .017) and food insecurity (P = .0002) also showed increasing distress with increased insecurity at baseline.

CONCLUSIONS

Patients who speak Spanish, identify as Hispanic, or are experiencing food and housing insecurity are at an increased risk for depression and anxiety, and could benefit from more support during their course of radiation therapy to minimize distress.

Searching for the "Holy Grail" of breast cancer recurrence risk: a narrative review of the hunt for a better biomarker and the promise of circulating tumor DNA (ctDNA)

BACKGROUND

This paper is a narrative review of a major clinical challenge at the heart of breast cancer care: determining which patients are at risk of recurrence, which require systemic therapy, and which remain at risk in the survivorship phase of care despite initial therapy.

METHODS

We review the literature on prognostic and predictive biomarkers in breast cancer with a focus on detection of minimal residual disease.

RESULTS

While we have many tools to estimate and refine risk that are used to individualize local and systemic therapy, we know that we continue to over treat many patients and undertreat others. Many patients also experience what is, at least in hindsight, needless fear of recurrence. In this review, we frame this dilemma for the practicing breast oncologist and discuss the search for what we term the "holy grail" of breast cancer evaluation: the ideal biomarker of residual distant disease. We review the history of attempts to address this problem and the up-to-date science on biomarkers, circulating tumor cells and circulating tumor DNA (ctDNA).

CONCLUSION

This review suggests that the emerging promise of ctDNA may help resolve a crticical dilemma at the heart of breast cancer care, and improve prognostication, treatment selection, and outcomes for patients with breast cancer.

Achievement of Target Gain Larger than Unity in an Inertial Fusion Experiment

On December 5, 2022, an indirect drive fusion implosion on the National Ignition Facility (NIF) achieved a target gain G_{target} of 1.5. This is the first laboratory demonstration of exceeding "scientific breakeven" (or G_{target}>1) where 2.05 MJ of 351 nm laser light produced 3.1 MJ of total fusion yield, a result which significantly exceeds the Lawson criterion for fusion ignition as reported in a previous NIF implosion [H. Abu-Shawareb et al. (Indirect Drive ICF Collaboration), Phys. Rev. Lett. 129, 075001 (2022)PRLTAO0031-900710.1103/PhysRevLett.129.075001]. This achievement is the culmination of more than five decades of research and gives proof that laboratory fusion, based on fundamental physics principles, is possible. This Letter reports on the target, laser, design, and experimental advancements that led to this result.

Multi-Institutional Experience of Proton Therapy for Rhabdomyosarcoma and Ewing Sarcoma in the Proton Collaborative Group (PCG) Prospective Registry

PURPOSE/OBJECTIVE(S)

To report on outcomes, acute toxicities, and the use of dose-escalation with proton therapy (PT) in patients with rhabdomyosarcoma and Ewing sarcoma in a prospective multi-institutional registry (PCG).

MATERIALS/METHODS

Data on patients with primary rhabdomyosarcoma and Ewing sarcoma treated with definitive PT (defined as ≥45 Gy) were queried from the PCG registry. A similar query was performed of our institutional database with IRB approval. Overall survival rates were calculated by Kaplan-Meier. Toxicities were scored using CTCAE v4.0.

RESULTS

A total of 354 patients across 10 institutions (203 rhabdomyosarcoma, 151 Ewing sarcoma) met the eligibility criteria. Median age was 9 years (Interquartile Range: 5-15). Median dose was 50.4 GyRBE for rhabdomyosarcoma patients (Range: 45-66 GyRBE) and 55.8 GyRBE for Ewing sarcoma patients (Range: 45-66 GyRBE). Median follow-up was 2.4 years (Range 0.3-12.3 years). Two-year overall survival rates were 81.1% (95% CI: 73.7%-88.5%) for rhabdomyosarcoma and 79.1% (95% CI: 71.7%-86.2%) for Ewing sarcoma. The Table lists the prescription doses delivered by tumor histology; 28.1% of rhabdomyosarcoma and 21.9% of Ewing sarcoma patients, respectively, received dose-escalated radiotherapy (defined as >50.4 Gy for rhabdomyosarcoma and >55.8 Gy for Ewing sarcoma). Excluding alopecia and skin desquamation, 153 patients (43.2%) developed any acute grade 2+ non-hematologic toxicity, while 49 patients (13.8%) developed one or more grade 3 toxicities. The most common grade 3 toxicities were anorexia/weight loss (7.3%), pain (7.3%) mucositis/esophagitis (4.8%), and nausea/vomiting (3.1%). One grade 4 toxicity (esophagitis) and no deaths were reported during treatment.

CONCLUSION

In this multi-institutional prospective registry, 28.1% of rhabdomyosarcoma and 21.9% of Ewing sarcoma patients received dose-escalated PT, with 13.8% of patients developing grade 3 toxicities. Long-term outcomes for disease control and late toxicity and anticipated cooperative group trial results are needed to fully assess the benefits and risks of dose-escalated radiotherapy for these tumors.

Optimizing Informed Consent in Cancer Clinical Trials

The concept of informed consent has evolved considerably over the course of the 20th century, leading to its establishment as a foundational ethical principle for the conduct of biomedical research in the United States. Even though it is now a highly regulated part of cancer research, the process of obtaining informed consent is often impeded by systemic, clinician, and patient factors that require both small- and large-scale intervention. New challenges and considerations continue to emerge due to innovations in clinical trial design, increases in utilization of genomic sequencing, and advances in genomic editing and artificial intelligence. We present a review of the history, policy, pragmatic challenges, and evolving role of the central ethical tenet of informed consent in clinical trials.

Multi-Institutional Experience of Proton Therapy for Osteosarcoma in the Proton Collaborative Group (PCG) Prospective Registry

PURPOSE/OBJECTIVE(S)

To report on the utilization of dose-escalated radiotherapy, acute toxicities, and survival following definitive proton therapy (PT) for osteosarcoma patients in a prospective multi-institutional study.

MATERIALS/METHODS

Data on patients with osteosarcoma treated with definitive intent PT were queried from the Proton Collaborative Group (PCG) prospective registry. A similar query was performed on an institutional database with IRB approval. Overall survival rates were calculated by Kaplan-Meier. Toxicities were scored using CTCAE v4.0.

RESULTS

Forty osteosarcoma patients across 9 institutions received definitive intent PT between 2011-2021 and met the eligibility criteria. Median age was 32 years (Range: 6-86 years). Median PT dose was 66.6 GyRBE (Range: 50.4-80.0 GyRBE); 38 patients received proton therapy alone, whereas 2 received combined proton/photon therapy. Seventeen (42.5%) patients received doses ≥70 GyRBE. Median follow-up was 3.1 years (Range: 0.9-10.5 years). One-year and three-year overall survival rates were 83.5% and 59.1%, respectively, with 14 deaths due to disease. Excluding skin desquamation and alopecia, 22 patients (55.0%) developed any acute grade 2+ toxicity, and 5 patients (12.5%) developed any grade 3 toxicities. No acute grade 4-5 toxicities were reported. The most frequent grade 2+ non-skin toxicities were fatigue (37.5%), anorexia/weight loss (17.5%), mucositis/esophagitis (22.5%), pain (20.0%), and nausea/vomiting (10.0%). The most frequent grade 3 toxicities were anorexia/weight loss (5.0%), mucositis/esophagitis (5.0%), and neurologic symptoms (5.0%).

CONCLUSION

In this multi-institutional study, 42.5% of osteosarcoma patients treated with PT received doses between 70-80 Gy, with 12.5% experiencing any grade 3 toxicity. Long-term outcomes for disease control, late toxicity, and quality-of-life are needed to more fully assess the benefits and risks of dose-escalated radiotherapy in this radioresistant tumor. The authors plan to assess the outcomes of osteosarcoma patients treated with dose-escalated radiotherapy for unresectable or gross residual disease in future studies.

Abstract ED8-1: Overview of the current state of the art – what patients and oncologists need to know

While radiation therapy plays a significant role in the treatment of breast cancer for many patients, the nuances of modern day radiation therapy are often poorly understood by both patients and referring providers. Radiation therapy techniques to reduce toxicity and improve treatment accuracy have rapidly evolved in the past decade. This session will introduce non-radiation oncologists to recent innovations that allow increased personalization of treatment based on anatomical variations. Methods to improve patient positioning will be discussed. Frequently utilized dosimetric techniques for breast radiotherapy will be described and compared, including Volumetric Modulated Arc Therapy (VMAT), Intensity Modulated Radiation Therapy (IMRT), and 3D conformal planning. New methods for patient monitoring during treatment and the purpose of respiratory gating will be reviewed. Finally, the impact of surgical therapies on radiation planning and delivery will also be examined. Attendees should leave the session having a greater understanding of the current available options for radiotherapy and rationale for the choice of treatment technique.

Abstract P2-03-01: Sarcopenia on baseline imaging is associated with toxicity-related discontinuation of endocrine therapy in women with early-stage hormone-positive breast cancer

Background Adjuvant endocrine therapy (ET) is standard of care in women with hormone receptor-positive (HR+) breast cancer (BC) with the goal to reduce recurrence. However, early discontinuation of ET occurs in 30-40% of women, largely attributable to toxicity, and leads to increased recurrence risk. There is considerable overlap in risk factors that predict toxicity from ET and chemotherapy, including age, co-morbidities, and geriatric conditions. Baseline low skeletal muscle area (SMA) on chest computed tomography (CT) is a surrogate marker for sarcopenia and predicts for significant toxicity and intolerance to chemotherapy in women with BC. No study has assessed the association of sarcopenia with toxicity-related discontinuation of ET in women with early-stage HR+ BC. Methods This single center retrospective cohort study included consecutive women with Stage 0-II HR+ BC who received ET and adjuvant radiotherapy (RT) from 01/2011-12/2017. Inclusion required a minimum of 5-year clinical follow-up after diagnosis. We used a validated deep learning pipeline to quantify SMA (cm2) at the tenth thoracic (T10) vertebral body on existing RT planning CT. The skeletal muscle index (SMI [cm2/m2] = SMA/(patient height (m))2) was calculated to adjust for patient height. Sarcopenia was defined as SMI< 32.3 cm2/m2, based on a previously validated independent cohort of young healthy women. The primary endpoint was toxicity-related discontinuation of ET less than 60 months after initiation of ET. Secondary endpoints included any NCI CTCAE v5.0 Grade 3-5 toxicity from ET and ipsilateral breast tumor recurrence. We assessed associations between ET discontinuation and SMI (continuous), as well as thoracic sarcopenia (dichotomous), using logistic regression adjusting for baseline characteristics. We used cox proportional hazards regression to assess disease-free survival (DFS), defined as ipsilateral breast tumor recurrence, locoregional recurrence, or distant metastasis adjusting for baseline and treatment characteristics. Results A total of 265 women (median age 67 years) met inclusion criteria. The majority of women had a comorbidity index of 0-1 (89%) and were Caucasian (89%). The median follow-up was 82 months, 5-year overall survival was 96% and 5-year DFS was 94%. Diagnoses included DCIS (12%), IDC (76%), or ILC (12%); most were T1 (69%) or T2 (18%) and N0 (85%), ER-positive (100%), PR-positive (85%), or HER2-negative (9%). Most common ET type was anastrozole (63%), letrozole (16%), and tamoxifen (17%). SMI (continuous) was not associated with older age, Charlson Comorbidity Index (CCI), race, or tumor stage. A total of 64 (24%) women experienced toxicity-related early discontinuation of ET. On multivariate analysis (MVA), lower SMI was associated with increased toxicity-related early discontinuation of ET (Odds Ratio [OR] 0.89 per 1 cm2/m2 SMI, p=0.001) independent of age, CCI, ET type, or receipt of adjuvant chemotherapy. Lower SMI was associated with higher risk of grade 3-5 toxicity from ET (OR 0.89 per 1 unit SMI, p=0.001) independent of age, CCI, ET type, or receipt of adjuvant chemotherapy. On MVA, sarcopenia was associated with higher risk of toxicity-related early discontinuation of ET (OR 2.43, p=0.019). DFS was associated with toxicity-related early discontinuation of ET (HR 8.06, p=0.005), grade 3 histology (HR 1.42, p=0.042), and multifocal disease (HR 2.55, p=0.040), but not age, histology, stage, or lymphovascular invasion (p>.05 for all). Conclusion Low baseline thoracic skeletal muscle is associated with toxicity-related early ET discontinuation in women with early-stage HR+ BC. Further studies should attempt to generalize this association to all HR+ BC who are candidates for ET. High-risk patients may be candidates for aggressive symptom management or alternative adjuvant therapies.

Abstract OT1-12-02: Preliminary report of the PRECISION Trial (Profiling Early Breast Cancer for Radiotherapy Omission): A Phase II Study of Breast-Conserving Surgery Without Adjuvant Radiotherapy for Favorable-Risk Breast Cancer

Background: Breast conserving surgery (BCS) is typically followed by adjuvant radiotherapy (RT) based on several landmark trials demonstrating improvements in disease control and survival. Since completion of these historical trials, the advent of molecular subtyping has revealed that breast cancer is not a single disease entity, but rather a class of cancers with differential risk profiles. We evaluated whether RT could be safely omitted following BCS for patients with the most favorable subtype as defined by the Prosigna PAM50 assay. Methods: We conducted a multicenter prospective single-arm cohort study with IRB approval and an FDA investigational device exemption (IDE). Eligible patients were women 50 to 75 years of age (inclusive) who had undergone BCS revealing tumors ≤2cm in size, that were estrogen or progesterone receptor positive (HR+), HER2 negative, grade 1-2, node negative (N0), with negative excision margins (no ink on tumor). Intent to take endocrine therapy was required. Upon registration, tumors were submitted for central Prosigna testing and those with Risk of Recurrence (ROR) score ≤40 were deemed eligible for the investigational omission of RT. The primary endpoint was the 5-year locoregional recurrence rate (LRR). Anticipating a total of 345 RT-omitting patients to enroll over 3.5 years, the study was designed with 90% power to exclude a 5-year LRR of 5% using a one-sample exponential test with one-sided type I error of 0.025. Results: From 2016 to 2020, 671 patients were registered from 13 centers, inclusive of affiliated regional network sites. Of these, 382 patients had a ROR Score ≤40 and opted to forego RT, comprising the main intention-to-treat (ITT) study population. Median age was 65 years (range 50 to 75), and median tumor size was 0.9 cm (range 0.1 to 2.0 cm). At a median follow-up of 26.9 months, 12 events were observed: 4 patients had ipsilateral in-breast recurrences, 7 had contralateral breast cancers, and 1 developed an unrelated melanoma. There were no regional-nodal or distant recurrences. The 2-year cumulative rate of LRR was 0.3% (95% CI: 0 – 1.0%). Of the 4 ipsilateral breast recurrences, 2 were in the same quadrant as the original primary tumor. Conclusion: In this preliminary report of the PRECISION trial, patients 50-75 years of age undergoing BCS and endocrine therapy for pT1N0 HR+ HER2-negative breast cancer with ROR score ≤40 had exceedingly low rates of LRR in the absence of adjuvant RT at a median follow-up of 26.9 months. Additional follow-up is required to determine whether these favorable results are durable.

Identifying Early-Phase Clinical Trial Participants at Risk for Experiencing Worse Clinical Outcomes

PURPOSE

To identify early-phase clinical trial (EP-CT) participants at risk for experiencing worse clinical outcomes and describe receipt of supportive care services.

METHODS

A retrospective review of the electronic health records of consecutive patients enrolled in EP-CTs from 2017 to 2019 examined baseline characteristics, clinical outcomes, and receipt of supportive care services. The validated Royal Marsden Hospital (RMH) prognosis score was calculated using data at the time of EP-CT enrollment (scores range from 0 to 3; scores ≥ 2 indicate poor prognosis). Differences in patient characteristics, clinical outcomes, and receipt of supportive care services were compared on the basis of RMH scores.

RESULTS

Among 350 patients (median age = 63.2 years [range, 23.0-84.3 years], 57.1% female, 98.0% metastatic cancer), 31.7% had an RMH score indicating a poor prognosis. Those with poor prognosis RMH scores had worse overall survival (hazard ratio [HR], 2.00; P < .001), shorter time on trial (HR, 1.53; P < .001), and lower likelihood of completing the dose-limiting toxicity period (odds ratio, 0.42; P = .006) versus those with good prognosis scores. Patients with poor prognosis scores had greater risk of emergency room visits (HR, 1.66; P = .037) and hospitalizations (HR, 1.69; P = .016) while on trial, and earlier hospice enrollment (HR, 2.22; P = .006). Patients with poor prognosis scores were significantly more likely to receive palliative care consultation (46.8% v 27.6%; P < .001), but not other supportive care services.

CONCLUSION

This study found that RMH prognosis score could identify patients at risk for decreased survival, shorter time on trial, and greater use of health care services. The findings underscore the need to develop supportive care interventions targeting EP-CT participants' distinct needs.

Ablation of the endoplasmic reticulum stress kinase PERK induces paraptosis and type I interferon to promote anti-tumor T cell responses

Activation of unfolded protein responses (UPRs) in cancer cells undergoing endoplasmic reticulum (ER) stress promotes survival. However, how UPR in tumor cells impacts anti-tumor immune responses remains poorly described. Here, we investigate the role of the UPR mediator pancreatic ER kinase (PKR)-like ER kinase (PERK) in cancer cells in the modulation of anti-tumor immunity. Deletion of PERK in cancer cells or pharmacological inhibition of PERK in melanoma-bearing mice incites robust activation of anti-tumor T cell immunity and attenuates tumor growth. PERK elimination in ER-stressed malignant cells triggers SEC61β-induced paraptosis, thereby promoting immunogenic cell death (ICD) and systemic anti-tumor responses. ICD induction in PERK-ablated tumors stimulates type I interferon production in dendritic cells (DCs), which primes CCR2-dependent tumor trafficking of common-monocytic precursors and their intra-tumor commitment into monocytic-lineage inflammatory Ly6C+CD103+ DCs. These findings identify how tumor cell-derived PERK promotes immune evasion and highlight the potential of PERK-targeting therapies in cancer immunotherapy.

Time toxicity in early phase clinical trials (EP-CTs)

236

Background: EP-CTs are an increasingly important treatment option for patients with cancer, yet often require intensive monitoring. Little is known about the time that EP-CT participants spend in-hospital, and how that time compares to study requirements. Methods: We retrospectively reviewed the electronic health record (EHR) of consecutive patients enrolled in EP-CTs at Massachusetts General Hospital from 2017-2019 to obtain patient characteristics (demographics and clinical factors) and EP-CT investigational agent (immunomodulatory therapy [IM], targeted inhibitor [TI], antibody drug conjugate [ADC]/chemotherapy prodrug). We identified protocol requirements by reviewing the study calendar for in-hospital days for any reason, including clinician visits and diagnostic tests. We identified the real-world number of days spent at the hospital by reviewing the EHR for in-hospital days. We used descriptive statistics to compare patient characteristics and outcomes for those with higher time toxicity, defined as 5+ real-world visits during the first 28 days on trial, versus lower time toxicity. Results: Among 421 patients (median age = 63.0 years, 56.9% female, 97.6% metastatic disease), 43.2% participated in IM trials, 43.0% TI, and 13.8% ADC. Most common tumor types were gastrointestinal (GI) (22.3%) and lung (20.0%). Over the first 28 days on trial, protocol requirements listed an average of 5.2 in-hospital days, yet real-world data demonstrated that patients had an average of 6.6 in-hospital days (p < 0.001). TI trial participants had the highest average number of anticipated protocol visits compared with those on other trials (5.5 [TI] vs 5.3 [ADC] vs 5.0 [IM], p = 0.027). In real-world data, those on ADC trials had the highest average number of visits (7.5 [ADC] vs 7.1 [TI] vs 5.7 [IM], p < 0.001). Those with 5+ real-world visits during the first 28 days were more likely to have GI cancer (25.8% vs 13.9%, p = 0.011) and less likely to have lung cancer (16.7% vs 27.9%, p = 0.011). Patients with more visits were also less likely to have traveled 50+ miles to the hospital (48.8% vs 59.8%, p = 0.04). Notably, 19.5% of patients (N = 82) were hospitalized during the first 28 days on trial, with an average length of stay of 4.9 days. Those with 5+ visits had fewer days, on average, from trial start to admission (371.9 vs 650.8, p < 0.001) and fewer days on trial (mean 156.0 vs 235.0, p = 0.001). There was no significant difference in days from trial start to death for those with higher versus lower time toxicity (mean 464.6 vs 526.4, p = 0.177). Conclusions: EP-CTs represent a potentially time-intensive treatment option, as we found that patients spend over one-fifth of their first 28 days on trial at the hospital for various visits. Our findings indicate that patients may often experience more in-hospital days than what the protocol states. These data could help inform patient-clinician discussions regarding EP-CT participation and the potential time toxicity involved.

Patient-reported hope, quality of life, symptom burden, coping, and financial toxicity in early-phase clinical trial participants

275

Background: Early phase clinical trials (EP-CTs) investigate novel treatment options in oncology, with recent advances in personalized therapy leading to improved outcomes and offering hope to patients with cancer. However, little research has sought to understand associations of patient-reported hope with quality of life (QOL), symptom burden, coping, and financial toxicity in EP-CT participants. Methods: We prospectively enrolled consecutive adults with cancer participating in EP-CTs at Massachusetts General Hospital from 04/2021-05/2022. Participants completed baseline surveys prior to treatment initiation that assessed hope (Herth Hope Index [HHI], higher scores indicate greater hope), QOL (Functional Assessment of Cancer Therapy-General), symptom burden (physical: Edmonton Symptom Assessment System [ESAS]; psychological: Patient Health Questionaire-4 [PHQ4]), coping (Brief COPE: self-blame, acceptance, denial, emotional support, active, behavioral disengagement), and financial toxicity (COST tool, higher scores indicate greater financial wellbeing). We used regression models to determine associations of hope scores with patient-reported QOL, symptom burden, coping, and financial toxicity. Results: Of 157 eligible patients, we enrolled 129 (enrollment rate 82.2%, median age = 62.5 years [range 33.0-83.0], 53.9% female, and 96.0% metastatic cancer). Most common cancer types were gastrointestinal (37.5%), breast (20.3%), lung (8.6%), and head and neck (7.8%). Patients had an average HHI score of 27.5 (range 15.3 – 36.0), with 30.5% reporting high levels of hope. We found associations of higher hope scores with better QOL (B = 0.24, p < 0.001) and lower symptom burden (ESAS-physical: B = -0.14, p < 0.001; PHQ4-depression: B = -2.07, p < 0.001; PHQ4-anxiety: B = -0.93, p = 0.001). We also found that hope scores were associated with patients’ coping (self-blame [B = -1.44, p < 0.001]; acceptance [B = 1.40, p < 0.001], denial [B = -1.12, p = 0.004], emotional support [B = 0.99, p < 0.001], active [B = 1.02. p = 0.001], behavioral disengagement [B = -2.52, p < 0.001]). Lastly, we found that higher hope scores were associated with greater financial wellbeing (B = 0.11, p = 0.026). Conclusions: In this prospective cohort study, we demonstrated a substantial proportion of EP-CT participants had high baseline hope and identified associations of hope scores with other important patient-reported outcomes. Specifically, we found novel associations of higher hope scores with better QOL, lower symptom burden, more adaptive coping mechanisms, and greater financial wellbeing, underscoring the importance of targeting these patient-reported outcomes when seeking to enhance the care experience of EP-CT participants.

Lawson Criterion for Ignition Exceeded in an Inertial Fusion Experiment

For more than half a century, researchers around the world have been engaged in attempts to achieve fusion ignition as a proof of principle of various fusion concepts. Following the Lawson criterion, an ignited plasma is one where the fusion heating power is high enough to overcome all the physical processes that cool the fusion plasma, creating a positive thermodynamic feedback loop with rapidly increasing temperature. In inertially confined fusion, ignition is a state where the fusion plasma can begin "burn propagation" into surrounding cold fuel, enabling the possibility of high energy gain. While "scientific breakeven" (i.e., unity target gain) has not yet been achieved (here target gain is 0.72, 1.37 MJ of fusion for 1.92 MJ of laser energy), this Letter reports the first controlled fusion experiment, using laser indirect drive, on the National Ignition Facility to produce capsule gain (here 5.8) and reach ignition by nine different formulations of the Lawson criterion.

Oncologists’ perspectives on individualizing dose selection for patients with metastatic cancer

1531

Background: The goal of treatment for patients with metastatic cancer (MC) is to prolong and maintain quality of life. Patients and oncologists have questioned the current paradigm of initial dose selection for systemic therapy and want additional information about the potential trade-offs between efficacy and toxicity. However, empirical data on oncologists’ dose selection strategies and beliefs is lacking. Methods: ASCO conducted an international survey of medical oncologists who treat patients with metastatic breast or gastrointestinal cancers. Survey questions addressed experience with and attitudes towards reducing the standard dose of the first cycle of systemic therapy to minimize potential toxicity. The survey was open November 14 to December 13, 2021. Results: Among 3,099 eligible ASCO members, 367 completed the survey (response rate 12%), including 117 general oncologists (GO), 142 breast specialists (BRS), and 108 GI specialists (GIS). 77% of respondents practice in the US, 94% had experience leading a clinical trial, and 50% had been caregivers or patients themselves. Most respondents (52%) reported reducing the first dose of systemic agents at least 10% of the time in patients with MC to minimize toxicities. GIS were more likely to report reducing the first dose at least 10% of the time (72% vs. 50% of GO and 51% of BRS, p <.005). Of those who dose reduce, 89% reported discussing potential tradeoffs between efficacy and toxicity with patients. Among 10 common breast cancer drugs, capecitabine (76%) was the most likely to be dose reduced at initiation while tamoxifen (4%) was the least likely. Among 10 common GI cancer drugs, regorafenib (78%), capecitabine (71%) and sorafenib (66%) were most commonly dose reduced at initiation, while bevacizumab (7%) and panitumumab (8%) were the least likely. Overall, 65% of respondents agreed it is acceptable to lower starting doses to reduce side effects even at the potential expense of efficacy, with younger clinicians more likely to agree vs. older clinicians (72% age < 50 vs. 55% age > 50, p <.005). While the majority (53%) believe that oncologists should start with the recommended dose and lower it in response to side effects, GIS were more likely to disagree with this approach compared to BRS or GO (57% vs. 37% and 36% respectively, p <.005). In contrast, 45% of respondents believe that oncologists should start at a lower dose and consider increasing the dose for future cycles if the drug is well tolerated. There was strong support (89%) for future trials that seek to determine the minimal effective dose as opposed to the maximum tolerated dose. Conclusions: Oncologists frequently dose reduce to avoid toxicity in patients with MC but practices and attitudes regarding dose reduction vary considerably. Further research is needed to establish optimal dosing during drug development and to support oncologists and patients in selecting the starting dose in clinical practice.

Relationship of travel distance with patient demographics, advance care planning, and survival in early-phase clinical trials (EP-CTs)

6558

Background: EP-CTs are often conducted at large academic centers, which may require some patients to travel further for their care. Little is known about either the distance EP-CT participants travel for their care or the association of distance traveled with patient characteristics and outcomes. Methods: We retrospectively reviewed the electronic health records of consecutive patients enrolled in EP-CTs at Massachusetts General Hospital from 2017-2019 to obtain patient characteristics (demographics and clinical factors) and outcomes (including time spent on trial, survival, and presence or absence of an advance care planning [ACP] discussion, defined as documentation of a code status or goals of care conversation in the medical record). We also used patients’ home zip codes to derive the social deprivation index (SDI; a composite demographic measurement from 0-100 quantifying social determinants of health, with higher numbers indicating more disadvantage). To estimate distance traveled, we calculated the miles traveled in one direction driving from home zip code to trial site. We used descriptive statistics to compare patient characteristics and outcomes for those traveling < 50 miles (short distance) versus those traveling 50+ miles (long distance). Results: Among 421 patients (median age = 63.0 years, 56.9% female, 97.6% metastatic disease), median distance traveled was 36.4 miles. Half of patients (n = 217; 51.5%) traveled 50+ miles to receive care on trial. There were no significant differences between those traveling short and long distances in most patient characteristics evaluated, including age (60.9 vs 60.6 years; p = 0.635), sex (53.9% female vs 57.6%; p = 0.447), race (85.3% white vs 84.8%; p = 0.346), marital status (71.8% married vs 69.3%; p = 0.586), insurance (51% private vs 54.4%; p = 0.266), cancer type (22.5% GI vs 21.2%; p = 0.666), prior lines of therapy (52.5% one-two lines vs 51.2%; p = 0.981), and performance status (62.3% ECOG 1 vs 66.8%; p = 0.270. However, those with a higher SDI score were less likely to travel a long distance for trial participation (mean SDI 36.7 for short distance vs 30.5 for long distance; p = 0.026). Patients traveling a long distance were less likely to have a documented ACP discussion (48.8% vs 66.7%; p < 0.001). We found no significant difference in time spent on trial between those traveling short and long distances (mean days: 98 vs 93.5; p = 0.175) or in time from coming off trial to death (mean days: 147.7 vs 153.7; p = 0.099). Conclusions: We found that half of EP-CT participants travel 50+ miles in one direction to their trial site, with disparities in travel distance based on the social deprivation index. Notably, those traveling long distances were less likely to have a documented ACP discussion. Our findings suggest several unmet needs in the EP-CT population and highlight opportunities for future intervention development.

Protocol requirements and logistical intensity of early-phase clinical trials (EP-CTs)

e18609

Background: EP-CTs are increasingly important options for patients with cancer and often involve intensive monitoring. Characterizing the time burden and logistical intensity of EP-CT protocols could help patients and clinicians make informed decisions about trial participation. Methods: We retrospectively reviewed the electronic health records of consecutive patients enrolled in EP-CTs at Massachusetts General Hospital from 2017-2019 to obtain baseline characteristics (demographics and clinical factors), EP-CT investigational agent (immunomodulatory [IM], targeted inhibitor [TI], antibody drug conjugate [ADC]/chemotherapy prodrug), and logistical intensity (visit frequency required per protocol and presence of extended visits). We defined visit frequency as the number of visits required per protocol within the first 28 days on trial. We defined an extended visit as six or more hours required in clinic on at least one day during the first 28 days on study. We evaluated associations among patient characteristics, investigational agents, logistical intensity, and time spent on trial. Results: Among 421 patients (median age = 63.0 years, 56.9% female, 97.6% metastatic disease), 43.2% were enrolled in IM EP-CTs, 43.0% TI, and 13.8% ADC/chemotherapy prodrug investigational agents. Patients enrolled on ADC/prodrug trials had the highest burden of metastatic disease (mean sites: 2.8 [ADC] vs 2.4 [TI] vs 2.3 [IM], p = 0.007) and oldest age (mean years: 64.0 [ADC] vs 61.7 [IM] vs 58.5 [TI], p = 0.003). However, those on ADC trials had the most days spent on trial (mean days: 78.3 [TI] vs 102.2 [IM] vs 131.8 [ADC], p = 0.003). Patients enrolled on TI trials had the highest required visit frequency compared with those enrolled on other trials (mean visits: 5.5 [TI] vs 5.3 [ADC] vs 5.0 [IM], p = 0.027). Additionally, those on TI trials were most likely to have an extended visit (82.3% [TI] vs 58.2% [IM] vs 29.3% [ADC], p < 0.001) and least likely to receive first in human therapy (38.1% [TI] vs 74.1% [ADC] vs 74.2% [IM], p < 0.001). Conclusions: In this cohort of patients participating in EP-CTs, we found that those enrolled on TI trials had the highest per protocol visit frequency and greatest likelihood of required extended visits. Those on ADC trials spent the most days on trial despite having the highest average age and burden of metastatic disease. These data highlight the time burden and logistical intensity of EP-CTs, underscoring certain trials as especially time intensive, which may help inform trial selection and participation.

Patient-reported hope, quality of life (QOL), symptom burden, and coping mechanisms in early phase clinical trial participants

12114

Background: Early phase clinical trials (EP-CTs) investigate novel treatment options in oncology, with recent advances in personalized therapy leading to improved outcomes and offering hope to patients with cancer. However, little research has sought to understand associations of patient-reported hope with QOL, symptom burden, and coping mechanisms in EP-CT participants. Methods: We prospectively enrolled consecutive adults with cancer participating in EP-CTs at Massachusetts General Hospital from 04/2021-01/2022. Participants completed baseline surveys prior to treatment initiation that assessed hope (Herth Hope Index [HHI], higher scores indicate greater hope), QOL (Functional Assessment of Cancer Therapy-General), symptom burden (physical: Edmonton Symptom Assessment System [ESAS]; psychological: Patient Health Questionaire-4 [PHQ4]), and coping mechanisms (Brief COPE). We used independent samples t-test to test for mean differences between groups and regression models to explore associations of hope with patient characteristics as well as patient-reported QOL, symptom burden, and coping mechanisms. Results: Of 92 eligible patients, we enrolled 85 (enrollment rate 92.4%, median age = 61.4 years [range 54.7-68.9]; 56.5% female, and 95.3% metastatic cancer). Most common cancer types were gastrointestinal (41.2%), breast (21.2%), lung (7.1%), and gynecologic (7.1%). Patients had an average HHI score of 28.2 (range 12.0-36.0), with 32.9% reporting high levels of hope. We found that married patients had higher mean hope score compared with non-married patients (28.9 versus 26.1, p = 0.024), those with children had higher mean hope scores than those without (28.9 versus 25.9, p = 0.013), and those who had received 3 or more lines of prior therapy compared with 1-2 (29.3 versus 27.2, p = 0.045) had higher hope scores. We also found associations of hope with patients’ QOL (B = 0.24, p < 0.001), symptom burden (ESAS-physical: B = -0.13, p = 0.001; PHQ4-depression: B = -2.26 p = < 0.001; PHQ4-anxiety: B = -0.94, p = 0.008), and coping (self-blame [B = -1.39, p = 0.003]; acceptance [B = 1.23, p = 0.002], denial [B = -1.09, p = 0.009], support [B = 1.06, p = 0.002], active [B = 0.73. p = 0.034], disengage [B = -3.24, p < 0.001]). Conclusions: In this prospective cohort study, we demonstrated that a substantial proportion of EP-CT participants had high baseline hope, and we identified several patient factors associated with their hope scores. We also found novel associations of higher hope scores with better QOL, lower symptom burden, and more adaptive coping mechanisms. Collectively, our findings highlight the potential for patient-reported hope to represent a key factor to consider when seeking to improve outcomes in EP-CT participants.

Hadrontherapy techniques for breast cancer

Radiotherapy plays a key role in breast cancer treatment, and recent technical advances have been made to improve the therapeutic window by limiting the risk of radiation-induced toxicity or by increasing tumor control. Hadrontherapy is a form a radiotherapy relying on particle beams; compared with photon beams, particle beams have specific physical, radiobiological and immunological properties, which can be valuable in diverse clinical situations. To date, available hadrontherapy techniques for breast cancer irradiation include proton therapy, carbon ion radiation therapy, fast neutron therapy and boron neutron capture therapy. This review analyzes the current rationale and level of evidence for each hadrontherapy technique for breast cancer.

Axillary Ultrasound Evaluation in Breast Cancer Patients: A Multidisciplinary Viewpoint and Middle Ground

Over the past decade, there has been a trend toward de-escalation of axillary surgery. Certain patients may now forego axillary lymph node dissection even in the setting of a positive sentinel lymph node biopsy (SLNB), and some patients may not even undergo a SLNB. However, there is wide variability in the imaging approach to assessing axillary lymph nodes in patients with breast cancer. Approaches range from performing axillary US in all patients with newly diagnosed breast cancer to omitting axillary imaging evaluation in all patients. This article provides a multidisciplinary middle ground approach for axillary nodal evaluation. The clinical impact and rationale for appropriate axillary nodal imaging are discussed and an imaging algorithm is proposed.

Proton Radiotherapy for Patients With Oligometastatic Breast Cancer Involving the Sternum

Introduction

A subset of metastatic breast cancer patients present with oligometastatic disease involving the sternum. Given the proximity to traditional target structures, a proton radiation field can be expanded to include this region, providing definitive therapy for patients who are otherwise metastatic. We evaluated the feasibility and outcomes of a small series of patients who received comprehensive nodal irradiation inclusive of an isolated sternal metastasis using proton pencil beam scanning.

Materials and Methods

Four patients with a diagnosis of metastatic breast cancer with an isolated metastasis to the sternum received multimodality therapy with curative intent and then underwent adjuvant pencil beam scanning with definitive treatment to the sternum. Dosimetric parameters and treatment outcomes were evaluated.

Results

With respect to treatment coverage, proton therapy was able to deliver comprehensive target structure coverage while maintaining modest doses to the organs at risk compared with photon techniques. At a median follow-up of 28 months from diagnosis, none of the patients have experienced relapse within the radiation portal or developed additional sites of metastatic disease.

Conclusion

Pencil beam scanning for oligometastatic breast cancer with isolated sternal lesions appears feasible without undue normal tissue exposure. Current treatment outcomes appear promising.

Serial measurement of global longitudinal strain among women with breast cancer treated with proton radiation therapy

Background

Conventional photon radiotherapy (RT) for breast cancer is associated with reduction in global longitudinal strain (GLS), an increase in both troponin and N-terminal pro-B type natriuretic peptide (NT-proBNP), and incident heart failure. The cardiac radiation exposure with proton-RT is reduced and, thus may be associated with less cardiotoxicity.

Objectives

To test the effect of proton-RT on GLS, troponin and NT-proBNP.

Methods

A prospective observational single center study of 69 women being treated with proton-RT for breast cancer. Serial measurements of GLS, high-sensitivity cardiac troponin-I (hs-cTnI), and NT-proBNP were performed at pre-specified intervals (pre proton-RT, 4 weeks after completion of proton-RT and again at 2 months post proton-RT).

Results

The mean age was 46±11 years, BMI was 25.6±5.2 kg/m2, 32% had hypertension and mean radiation dose to the heart and left ventricle (LV) were 0.44 Gy and 0.12 Gy respectively. There was no change in LV ejection fraction (pre proton-RT vs. 4-weeks post proton-RT vs. 2 months post proton-RT, 65±5 vs. 66±5 vs. 64±4%, p=0.15), global GLS (−21.7±2.7 vs. −22.7±2.3 vs. −22.8±2.1%, p=0.24) or segmental GLS from pre-to post proton-RT. Similarly, there was no change in hs-cTnI or NT-proBNP with proton-RT. However, post proton-RT, we found that patients with a history of hypertension had lower GLS when compared to women without hypertension (−21.3±3.5 vs. −24.0±2.4%, p=0.006).

Conclusion

Proton-RT did not impact LV function, or associate with an increase in biomarkers. These data support the potential cardiac benefits of proton-RT compared to conventional RT.

Colchicine in patients with acute myocardial infarction: an updated meta-analysis of randomized controlled trials

Background

Improvement in cardiovascular outcomes and treatment with anti-inflammatory agents have been the subject of many research. Colchicine inhibits tubulin polymerization and is used in treating pericarditis. Recent studies have shown its benefit when used for coronary events. The objective of this meta-analysis is to reexamine the role of colchicine in reducing cardiovascular events in acute coronary syndromes in light of more recent trials.

Methods

A systematic search for randomized controlled trials which involves use of colchicine and acute coronary syndrome was done using PubMed, Google Scholar, MEDLINE and Clinicaltrials.gov. Studies done in the last decade and those involving human subjects were included in the study.

Results

Seven RCT's (n: 11,282) were included in this meta-analysis comparing colchicine vs. placebo. Dose ranged from 0.5mg/day to 1mg/day. Among patients being treated for ACS, colchicine was associated with a significant reduction in composite cardiovascular outcomes (RR 0.69, 95% CI 0.60 – 0.79, P&lt;0.ehab724.12731), unstable angina (RR 0.67, 95% CI 0.55 – 0.82, P&lt;0.0001), and myocardial infarction (RR 0.75, 95% CI 0.62 – 0.92, P&lt;0.005,). Gastrointestinal events were evident in the colchicine group with no statistical difference between the two (RR 1.28, 95% CI 0.98 – 1.67, P 0.07).

Conclusion

Use of colchicine reduces composite cardiovascular outcomes, recurrence of unstable angina and MI among patient who had ACS. There was no statistically significant difference between colchicine and placebo in terms of gastrointestinal events. It is possible that colchicine be part of the standard treatment in patients with acute coronary syndrome.

Time burden and logistical intensity of early-phase clinical trials (EP-CTs)

84

Background: EP-CTs are increasingly important options for patients with cancer and often involve intensive monitoring. Thus, characterizing the time burden and logistical intensity of EP-CTs could help patients and clinicians make informed decisions regarding trial participation. Methods: We retrospectively reviewed the electronic health records of consecutive patients enrolled in EP-CTs at Massachusetts General Hospital from 2017-2019 to obtain baseline characteristics (demographics and clinical factors), EP-CT investigational agent (immunomodulatory therapy [IM], targeted inhibitor(s) [TI], antibody drug conjugate [ADC]/chemotherapy prodrug), and logistical intensity (trial visit frequency, presence of extended visits, distance traveled in one direction from home zip code to trial site). We defined visit frequency as the number of visits per protocol within the first 28 days on trial. We defined an extended visit as six or more hours in clinic on at least one day during the first 28 days on study. We investigated associations among patient characteristics, investigational agent, and logistical intensity. Results: Among 421 patients (median age=60.6 years, 55.8% female, 97.4% metastatic disease), most (73.6%) had two or more sites of metastatic disease. EP-CTs included 43.2% IM, 43.0% TI, and 13.8% ADC/chemotherapy prodrug. Patients enrolled in ADC/prodrug trials had the highest burden of metastatic disease (mean sites: 2.8 [ADC] vs 2.4 [TI] vs 2.3 [IM], p = 0.007) and oldest age (mean years: 64.0 [ADC] vs 61.7 [IM] vs 58.5 [TI], p = 0.003). Patients enrolled on TI trials had the highest visit frequency compared with those enrolled on other trials (mean visits: 5.5 [TI] vs 5.3 [ADC] vs 5.0 [IM], p = 0.027) and the fewest days spent on trial (mean days: 78.3 [TI] vs 102.2 [IM] vs 131.8 [ADC], p = 0.003). Patients enrolled on TI trials were also most likely to have an extended visit (82.3% [TI] vs 58.2% [IM] vs 29.3% [ADC], p < 0.001) and least likely to receive first in human therapy (38.1% [TI] vs 74.1% [ADC] vs 74.2% [IM], p < 0.001). Distance traveled from home to clinic did not significantly differ across trial type (median miles traveled: 35.1 [TI] vs 34.1 [IM] vs 33.2 [ADC], p = 0.884). Conclusions: In this cohort of patients participating in EP-CTs, we found that a plurality enrolled in IM studies. Those receiving ADC/prodrug regimens were older and had a higher burden of disease. On average, patients participating in EP-CTs had over five visits in the first month, with those enrolled on TI trials having the highest visit frequency and greatest likelihood of extended visits. Patients on TI trials also spent the fewest total days on trial. Despite the lack of significant differences in distance traveled, most patients were still traveling over 30 miles to get to the trial site. These data highlight the time burden and logistical intensity of various EP-CTs, which may help inform patient-clinician discussions about trial participation.

Identifying early-phase clinical trial (EP-CT) participants at risk for poor outcomes

301

Background: EP-CTs investigate novel treatment options, with recent advances in personalized therapy leading to increased response rates, decreased toxicity, and improved survival. Identifying EP-CT participants at risk for poor outcomes could help identify those who may benefit most from targeted supportive care efforts. Methods: We retrospectively reviewed the electronic health records of consecutive patients enrolled in EP-CTs from 2017-2019 to obtain baseline characteristics (demographics and clinical factors), clinical outcomes (survival, time on trial, completion of dose-limiting toxicity [DLT] period, emergency room [ER] visits, hospitalizations, and hospice use), and receipt of supportive care services before/during trial (palliative care, social work, physical therapy [PT], and nutrition). We calculated the validated Royal Marsden Hospital (RMH) prognosis score using data at the time of EP-CT enrollment based on patients’ lactate dehydrogenase, serum albumin, and number of sites of metastasis. RMH scores range from 0-3, with scores of 2+ indicating a poor prognosis. We examined differences in patient characteristics, clinical outcomes, and receipt of supportive care services based on the RMH prognosis score. Results: Among 350 patients (median age = 63.2 years [range 23.0-84.3]; 57.1% female, 98.0% metastatic cancer), the most common cancer types were lung (23.4%), gastrointestinal (20.3%), and breast (12.0%). Nearly one-third (31.7%) had an RMH score indicating a poor prognosis. Patients with a poor prognosis RMH score had a worse performance status (ECOG ≥1: 80.2% vs 58.1%, p <.001) and more prior treatment (3+ prior lines: 48.6% vs 34.7%, p =.001) than those with a better prognosis score. Those with a poor prognosis RMH score had worse survival (median: 147 vs 402 days, p <.001) and shorter time on trial (median: 49 vs 84 days, HR = 1.53, p <.001), as well as a lower likelihood of completing the DLT period (72.1% vs 80.8%, p =.015). Patients with a poor prognosis score had a higher risk for ER visits (HR 1.66; p =.037) and hospitalizations (HR 1.69; p =.016) while on trial, with earlier hospice enrollment (HR 2.22; p =.006) following the trial. Patients with a poor prognosis score were significantly more likely to receive palliative care before/during trial (46.8% vs 27.6% p =.001), but not social work (41.4% vs 41.4% p = 1.00), PT (44.1% vs 34.7%; p =.098), or nutrition (40.5% vs 37.2%; p =.557). Conclusions: EP-CT participants represent a unique population of patients with advanced cancer, and we identified a group at risk for particularly poor outcomes, including worse survival, shorter time on trial, and greater use of healthcare services. Although patients with a poor prognosis score had higher rates of palliative care use, under half received supportive care services, underscoring the need for efforts to prospectively target these patients with interventions that address their supportive care needs.

Supportive care services and goals of care in early phase clinical trials (EP-CTs)

26

Background: EP-CTs investigate novel therapeutic approaches for patients with cancer, but little is known about the use of supportive care services and timing of goals of care (GOC) discussions in EP-CTs. Methods: We conducted a retrospective review of consecutive patients with cancer enrolled on EP-CTs at Massachusetts General Hospital from 2017-2019. We collected information about patients’ demographic/clinical characteristics, use of supportive care services (palliative care [PC], social work [SW], physical therapy [PT], and nutrition), as well as documentation of GOC discussions and code status (before/during EP-CT vs after/never) via chart review. We examined patient characteristics associated with earlier receipt of supportive care services (before/during EP-CT vs after/never) and compared differences in the timing of GOC discussions and code status documented based on the receipt of supportive care services. Results: Among 425 patients enrolled on EP-CTs (median age 63.0; 56.0% female; 97.4% metastatic cancer; 22.1% gastrointestinal cancer), under half received supportive care services before/during trial (PC: 33.2% before/during, 66.8% post/never; SW: 41.9% before/during, 58.1% post/never; PT: 38.4% before/during, 61.6% post/never; and Nutrition: 33.2% before/during, 62.1% post/never). We identified the most common reasons for consulting each of the supportive care services (PC: 82.4% symptom management and 12.4% GOC; SW: 65.3% adjustment to illness and 23.8% referral for resources; PT: 44.8% safety/discharge planning and 24.6% mobility concerns; Nutrition: 73.2% for symptoms of anorexia/poor appetite and 21.5% nutrition assessment). Patients with GI cancer were more likely than those with other cancers to receive PC and SW before/during EP-CT (PC: 29.8% v 18.3%, p =.009; SW: 27.5% v 18.2%, p =.025). Earlier PC was associated with earlier hospice referral (HR = 1.95, p =.014) and shorter survival (HR = 1.54, p <.001). Patients receiving earlier supportive care services were more likely to have GOC discussions documented earlier (PC: 65.2% v 13.0%, p <.001; SW: 41.0% v 22.7%, p <.001; PT: 38.7% v 25.2%, p =.005; Nutrition: 39.1% v 25.0%, p =.002). Patients with earlier PC were more likely to have earlier documented code status (46.8% v 24.3%, p <.001), but not for any other service. Conclusions: In this cohort of patients with advanced cancer, under half received supportive care services before/during their participation in EP-CTs. We found that symptom management represented a common reason for referral to supportive care, highlighting the needs of this population. Patients who received earlier supportive care services were more likely to have earlier documentation of GOC discussions, with those receiving earlier PC having code status documented earlier and also experiencing earlier hospice use and shorter survival. These findings underscore the utility of supportive care services in EP-CTs.

Targeting cancer cell kinase PERK incites antitumor immunity by inducing immunogenic cell death and reprograming tumor-linked immunosuppressive myelopoiesis

The tumor microenvironment incites sustained endoplasmic reticulum (ER) stress in infiltrating T and myeloid cells, which impairs their antitumor potential through intrinsic activation of PKR-like endoplasmic reticulum kinase (PERK). Nonetheless, the immunomodulatory role of PERK activation in the tumor cell compartment remains unknown. Using multiple melanoma models, we established that PERK ablation (PERKKO) in cancer cells culminates in caspase-independent immunogenic cell death (ICD) in response to ER stress. In vivo, PERKKO cells underwent ICD and released immunostimulatory factors including HMGB1, ATP, calreticulin and type I interferons which provoked a dramatic anti-tumor response and induction of the abscopal effect. Immunologically, PERKKO tumor cells undergoing ICD spurred influx of CCR2-dependent monocyte-derived dendritic cells (MoDCs) and tumor infiltration of activated antigen-specific T cells. Moreover, PERK deletion in tumor cells triggered systemic expansion of myeloid precursors and promoted their differentiation into MoDCs via type I interferon signaling. Notably, MoDC-induced T cell responses in PERKKO tumors impaired B16-F10 tumor progression and enabled complete rejection of BrafV600E-SM1 tumors. Substantiating the translational potential of our work, inhibition of PERK in melanoma-bearing hosts resulted in significant anti-tumor effects. Also, TCGA analyses of melanoma patients showed that PERK signaling or repressed ICD marker expression coincided with shorter overall survival. Collectively, these results demonstrate that targeting PERK in tumor cells can offer the dual benefit of inducing ICD and reprogramming myelopoiesis to drive protective antitumor immunity.

Abstract SP069: Strategies to reduce cardiac toxicity

Approximately 60-70% of breast cancer (BC) patients receive radiation therapy (RT) as part of their care. Breast or chest wall RT improves locoregional control for BC and also improves BC survival in select populations. However, RT to the cardiac silhouette can be cardiotoxic and radiation induced cardiac toxicity (RIC) affects many breast cancer survivors. The likelihood of RIC is radiation dose dependent and can manifest in multiple forms including cardiovascular disease, heart failure, and/or pericarditis. The risk of cardiovascular disease among patients receiving RT for breast cancer increases linearly with mean heart dose exposure, with no minimum safe threshold. Prior studies have shown an increased risk of both major coronary events and heart failure within 5 years of RT among women with breast cancer, though the latency can be pronounced (10-20 years from exposure) and is further influenced by patient age at treatment as well as pre-existing cardiac risk factors. Therefore, the purpose of this talk is to: 1) discuss the nature and timing of RIC, including those patients most at risk of developing RIC, 2) review national and international cardiology-based guidelines for patient management after chest radiotherapy and 3) detail advances in cardiac sparing radiation techniques intended to reduce the risk of RIC. Ongoing research regarding novel detection and prevention strategies will be highlighted.

The adjuvant use of capecitabine for residual disease following pre-operative chemotherapy for breast cancer: Challenges applying CREATE-X to a US population

INTRODUCTION

The CREATE-X study, conducted in Japan and South Korea, established capecitabine as an adjuvant treatment option for patients with triple negative breast cancer (TNBC) who have residual disease (RD) following neoadjuvant anthracycline or taxane-based chemotherapy. However, there are no reports on the tolerability and outcomes of adjuvant capecitabine in the US setting following publication of the CREATE-X data.

METHODS

We retrospectively collected treatment and tolerability data from the medical records of the first 23 TNBC patients who received adjuvant capecitabine for RD post neoadjuvant chemotherapy at our institution. Disease-free survival was assessed using the Kaplan-Meier method.

RESULTS

The median starting dosage of capecitabine was 1871 mg/m²/day, most commonly divided into two daily doses on days 1-14 of each 21 day cycle. 34.8% of patients completed the treatment as prescribed. Side effects associated with treatment were common with 69.6% of patients experiencing hand-foot syndrome, 39.1% of patients experiencing diarrhea, and 13.0% of patients requiring hospitalization for side effects. Of 23 patients treated with adjuvant capecitabine, 34.8% completed the planned dose, 30.4% completed with dose reduction, and 34.8% discontinued early. At a median follow-up time of 14 months, the median disease-free survival was 22 months, with 30.4% of patients experiencing recurrence.

CONCLUSION

Tolerability was poor overall compared to the CREATE-X cohort. Administering adjuvant capecitabine for TNBC patients with residual disease in the United States is challenging given differences in tolerability. More research is needed to understand how poor tolerability will affect the efficacy of this approach in the US population.

Palliative care referrals in patients with advanced cancer on early-phase cancer clinical trials (EP-CTs)

29

Background: EP-CTs investigate novel therapeutic approaches for patients with cancer, but little is known about the utilization of supportive care services, specifically palliative care (PC), in this population. Methods: We conducted a retrospective review of consecutive patients enrolled on EP-CTs at the MGH Cancer Center from 2017-2019. Sociodemographic and clinical variables, including utilization of PC services, were obtained via chart review. Details of the PC evaluation were compared between patients who received first referral to PC while enrolled on an EP-CT versus those who received a PC referral at any point after diagnosis. Results: Among 426 patients enrolled on EP-CTs (median age 63 years; 44% male), 249 (59%) received a PC referral at any time following a diagnosis of cancer (median age 57 years, 58% male). Eighty-six (35%) were referred prior to enrollment on EP-CT, 44 (18%) were referred while on EP-CT, and 119 (48%) were referred post-EP-CT. Patients referred on EP-CT were younger (median 56 vs 63 years, p < 0.0001) than those enrolled on EP-CTs. For patients referred while on EP-CT, 48% had a PC consult within 30 days of enrollment (range: 0-530 days); median number of PC visits was 3 (range: 0-37); median time from first PC consult to death or termination of EP-CT was 32 days (range: 1-213). Of 44 patients referred on EP-CT, 2 (5%) died while on EP-CT. Of the remaining patients, median time from first PC consult to date of death was 79 days (IQR: 45-178 days). Most common reasons for referral included pain (22, 50%), non-pain symptoms (21, 48%), and goals of care/advanced care planning (20, 45%). Of these referrals, 13 (30%) were initiated as inpatients versus 31 (70%) as outpatients. Pain was most commonly cited for outpatient referral (35%), followed by non-pain symptoms (25%) and goals of care (23%). Non-pain symptoms (40%) and goals of care (36%) were most commonly cited reasons for inpatient referral, followed by pain (24%). Of referrals while on EP-CT, 23 (52%) were made by EP-CT staff, including MD and APP, 7 (16%) from the primary oncologist, and 1 (2%) was self-referral. 26 (57%) of patients referred to PC during trial were also referred to hospice, with a median time from last PC consult to hospice referral of 24 days (range: -2-322). Conclusions: A majority of patients with advanced cancer enrolled on EP-CTs received a PC referral. The timeline and method of referral varied, but most patients did not receive a referral until or following enrollment on an EP-CT. Future work will focus on developing a standard referral protocol for patients enrolled on EP-CTs.

Oncologist experiences regarding patient-recorded clinical encounters: Implications for the patient-doctor relationship

290

Background: The high prevalence of smartphone use means that most patients can easily audio record medical consultations. Oncologists’ attitudes towards recording visits are unknown yet may impact patient care. Methods: A mail survey of oncologists practicing at 5 U.S. Alliance for Clinical Trials in Oncology sites collected information on clinicians’ beliefs, preferences, and practices regarding patient-initiated recordings, along with sociodemographic and practice characteristics. Descriptive statistics and bivariate analyses were calculated. Results: Of 523 eligible oncologists, 352 (67%) completed the survey. Median age was 47 years, 33% were female, and 86% worked in an academic setting. 53% were medical oncologists, 30% surgical oncologists, and 17% radiation oncologists. Virtually all (93%) reported experience with patients recording visits, 79% at least weekly. The majority (74%) perceived that patients record visits in order to help understand treatment choices. While 79% reported that they “always” agree to recordings, 26% reported discomfort. Nearly one-third (29%) reported concerns about liability, 26% felt recording made discussion less natural, and 18% felt recording changed the way they conveyed information. Although 86% agreed that patients have the right to record visits, nearly all felt physician permission was required and 53% reported having been previously recorded without permission. Only 51% believed recording had a positive impact on the patient-doctor relationship. One-quarter (28%) felt that recording led to a less detailed conversation and 33% felt it contributed to avoidance of difficult topics, such as prognosis. Most preferred the patient/family taking notes or having access to a written summary. Views did not vary significantly based on practice setting, specialty, or region of the country. Older age and greater years in practice were associated with both greater comfort with recording and the perception that recording has a positive impact on the patient-doctor relationship (p < 0.001). Conclusions: While most oncologists report comfort with audio recording and recognize benefits for patients, a substantial minority have reservations about its impact on clinical discussions and their liability exposure. Adopting clear institutional policies about recording could help address some concerns, such as surreptitious recording, while ensuring that patients’ interests are served.

Involvement of social work services in patients with advanced cancer in early-phase clinical trials (EP-CTs)

28

Background: Early integration of supportive care in patients with advanced cancer has improved quality of life, symptom burden, and survival. Participants in EP-CTs often are highly pre-treated and the demands of participation can exacerbate financial and psychosocial concerns. Integration of social work services can address a broad scope of concerns including behavioral health, psychosocial needs, physical health, and financial concerns. Little data exists regarding the use of social work services in this patient population. Methods: We conducted a retrospective chart review of consecutive patients enrolled in EP-CTs at the MGH Cancer Center during 2017-2019. Information including sociodemographic data, clinical variables, and the use of social work services were captured from the electronic health record. We reviewed documentation in social work notes to determine reason for referral while participating on trial. Results: Of 426 EP-CT participants, 64% ( n = 272) received social work consultations at any time during their cancer course (consultations occurred a median of 23 months [range 0 – 444] following diagnosis). Compared to those who did not receive consultation, patients receiving consultation were younger (median age 60.5 years vs 65 years, p < .001) and more likely to have children (63% vs 46%, p < .001). More than half (59%, n = 159) of consultations occurred prior to EP-CT enrollment, while 14% (n = 39) were during patients’ time on EP-CT. The most common reasons for referral on trial included adjustment to illness (41%), limited patient resources (23%), and home/family support (15%). A quarter of referrals (27%, n = 74) were initiated after patients left the trial (27%, n = 74). There were no significant differences in demographic or clinical variables between those referred on EP-CT versus before or after EP-CT. For those who received social work consultation while on EP-CT, median time from date on treatment to consultation was 18 days (0 – 182 days) while median time on EP-CT was 55 days (2 – 576 days). Patients received a median of 2 visits (1 – 20) while on EP-CT. Physicians and research nurses were most likely to refer patients (31% vs 26%, respectively) while 10% of patients self-referred to social work. Conclusions: Over half of EP-CT participants received social work consultations during their cancer course. Most patients who received consultation on an EP-CT did so for psychosocial support. Future research should focus on determining how best to integrate social work into the care of EP-CT participants.

Understanding the supportive care needs of early-phase cancer clinical trial (CT) participants

26

Background: Early phase CTs investigate novel therapeutic approaches for patients with cancer, but little is known about the use of supportive care services among participants in early phase CTs. Methods: We conducted a retrospective chart review of consecutive patients enrolled in Phase 1 CTs from 2017-2019, capturing sociodemographics, clinical data, and use of supportive care services from the electronic health record. We calculated the Royal Marsden Hospital (RMH) prognostic score using data at the time of CT trial enrollment based on patients’ lactate dehydrogenase, albumin, and number of sites of metastasis. The RMH score ranges from 0-3, with scores of 2+ indicating a poor prognosis. We explored differences in patient characteristics, supportive care use, and clinical outcomes based on the RMH prognosis score. Results: Among 426 patients treated on Phase 1 CTs during the study period, the median age was 63.0 years (range 20.5-85.2 years), and most were female (56.1%), white race (85.1%), and had metastatic cancer (97.7%). The most common cancer types were gastrointestinal (22.1%), lung (20.0%), and breast (10.6%) cancer. Under half (31.6%) had an RMH score indicating a poor prognosis. Patients with a poor prognosis score had a worse performance status (ECOG ≥1: 80.2% v 58.3%, p < .001) and more prior treatment (3+ prior lines: 49.5% v 35.0%, p = .001) compared to those without a poor prognosis score. Those with a poor prognosis score were more likely to receive palliative care before or during CT participation (40.5% v 27.1%, p = .011). We observed no significant differences in the rates of nutrition (69.1% v 64.0%), social work (62.2% v 63.8%), or physical therapy (64.5% v 61.7%) consults between those with and without a poor prognosis score. We found that those with an RMH score indicating a poor prognosis had a shorter time on trial (median: 49 vs 87 days, p < .001) and worse survival (median: 139 v 379 days, p < .001). Conclusions: Early phase CT participants represent an advanced cancer population with unique supportive care needs, and we identified a group with a particularly poor prognosis for whom earlier intervention with supportive care services may be needed. Our findings highlight the need to prospectively examine these characteristics along with patient-reported outcomes to better understand the distinct supportive care needs of this population and guide the development of targeted interventions.

Abstract CT271: PRECISION (Profiling early breast cancer for radiotherapy omission): A phase II study of breast-conserving surgery without adjuvant radiotherapy for favorable-risk breast cancer

Background: Radiation therapy (RT) following breast conserving surgery (BCS) is known to improve locoregional and distant control in women with invasive breast cancer; however, RT does pose significant cost and potential risk, including concern for cardiopulmonary toxicity and secondary malignancy. Randomized trials show that the omission of RT among older women with otherwise favorable-risk breast cancer does not affect overall survival (OS) at 10 years, and modestly increases the risk of local recurrence (LR). Nevertheless, there is little prospective support for RT omission in younger women. Moreover, risk stratification in the randomized prospective studies to date relies on limited methods with potentially low fidelity at distinguishing luminal subtypes. Enhanced molecular profiling techniques could better discern tumor biology and, in turn, more precisely assess risk. PAM-50 is an expression profile of 50 genes used to classify breast cancer intrinsic subtype with consequent prognostic implications. The goal of this study is to identify low-risk breast cancer patients with luminal A subtype who may feasibly omit RT from their therapeutic regimen. Methods: This is a phase II prospective cohort study (NCT02653755) designed to assess the safety of treatment de-escalation (omission of RT) in women with favorable-risk invasive breast cancer following BCS. Eligibility criteria include female patients with invasive breast cancer, age 50-75, with tumors less than or equal to 2cm, negative surgical margins, ER+ or PR+ and HER2- disease, grade 1 or 2, no lymph node involvement, and no plans for chemotherapy or biologic therapy, who are eligible for and willing to receive endocrine therapy. Tumor samples from eligible patients will undergo PAM-50 transcriptional profiling using the Nanostring Prosigna assay. A low Risk of Recurrence (ROR) score, corresponding to the luminal A subtype, will permit patients to forego radiotherapy should they so choose. The primary endpoint is 5-year risk of local or regional recurrence of invasive or in situ breast carcinoma within the ipsilateral breast or regional lymph nodes. Study enrollment began in May 2016.

Factors associated with frequent insomnia among breast cancer survivors

e24098

Background: Insomnia is common among breast cancer (BC) survivors and often goes unrecognized and untreated. We sought to evaluate the association between frequent insomnia and potentially modifiable contributing factors to inform development of a comprehensive clinical program to address insomnia among patients with breast cancer. Methods: We adapted a 1-page survey from the National Comprehensive Cancer Network Guidelines for Survivorship, which was administered to BC survivors at oncology or primary care follow-up visits at our academic center and community based sites. The survey included 23 plain-language statements regarding symptoms, lifestyle concerns, and financial worries. Patients reported the frequency of concerns using a 5-point Likert scale (0 = never to 5 = always). We evaluated the frequency of insomnia and association between insomnia and 6 common concerns hypothesized to contribute among this population: emotional distress, fatigue, pain, hot flashes, fear of cancer recurrence, and healthcare-related financial stress. Prevalence of symptoms was dichotomized, grouping “very often” and “always” as “frequent”, and “sometimes,” “rarely”, and “never” as “infrequent”. Descriptive analysis was performed and associations between insomnia and other concerns were evaluated with Fisher’s exact test. Results: Among 192 patients (median age 59, range 34-92), 46 (24%) reported frequent insomnia (“I have problems falling or staying asleep”). Most patients (58%) reported experiencing insomnia at least “sometimes”, while 20% answered “rarely” and 23% “never”. Overall, 14% of survivors reported frequent anxiety/depression, 15% fatigue, 27% pain, 19% hot flashes, and 23% fear of recurrence. Only 6% of patients reported frequent financial worries due to healthcare costs. Emotional distress (p=0.016), fatigue (p≤0.001), pain (p≤0.001), hot flashes (p=0.017), and fear of recurrence (p≤0.01) were each associated with frequent insomnia. Conclusions: BC survivors who experience frequent insomnia are more likely to report emotional distress, fatigue, pain, hot flashes, and fear of recurrence, compared to those with infrequent insomnia. A clinical program designed for the management of insomnia may benefit from targeting these potentially contributing factors.

Abstract P2-21-01: Feasibility of a multidisciplinary diagnostic breast research biopsy project

Background: The comprehensive analysis of clinically annotated tissue specimens from those with either benign, high risk or malignant breast findings is critical to improve the understanding of breast cancer biology and treatment. Through a multidisciplinary team approach, we designed a protocol to allow a breast research biopsy to be collected with informed patient consent concurrent with the diagnostic biopsy at our institution. Here we describe the feasibility of the project.

Methods: IRB approval was obtained for the prospective collection and storage of clinically-annotated specimens, including breast biopsy cores, excess surgical tissue from breast surgery, and optional blood collection. Potential participants are identified through the list of scheduled breast biopsies at the Massachusetts General Hospital breast imaging center. Eligible patients are those ≥ age 18 undergoing a clinical breast biopsy. Research consent is obtained in the procedure room immediately following the clinical consent process and prior to the clinical biopsy. Following completion of standard clinical biopsy workflow, two research core biopsy specimens are obtained with a core biopsy needle ranging from 9 to 18 gauge. The first research specimen is flash frozen and stored on dry ice to preserve high molecular weight DNA and RNA. The second sample is cryopreserved in DMSO or a related agent to allow viable cell recovery. All consented patients are entered into a prospective database in REDCap. Medical records of the participating patients are reviewed periodically to collect data on patient demographics, tumor characteristics, and long-term outcomes.

Results: From 1/17/19 through 6/28/19, 144 patients were approached. 77.8% of patients consented, resulting in 96 lesions being biopsied for research. Of these, 45.8% were invasive carcinoma, 3.1% were DCIS, 6.1% were high risk lesions, and 44.8% were benign. Among the invasive breast cancers, 78.6% were hormone receptor-positive (HR+) and human epidermal growth factor receptor 2-negative (HER2-), 9.5% were HER2+, and 11.9% were triple negative.

Conclusion: We demonstrated that an upfront breast research biopsy program in patients presenting for initial diagnostic breast biopsy is feasible, with high rates of patient participation. Overall, 77.8% of approached subjects agreed to a concurrent research breast biopsy at the time of diagnostic biopsy. This approach may provide a high yield mechanism to generate a rich tissue repository with low cost and marginal additional time commitment by patient and providers that can support novel, cross-disciplinary research. A number of collaborative research projects are planned.

ESTRO ACROP consensus guideline for target volume delineation in the setting of postmastectomy radiation therapy after implant-based immediate reconstruction for early stage breast cancer

Immediate breast reconstruction (IBR) rates after mastectomy are increasing. Postmastectomy radiation therapy (PMRT) contouring guidelines for target volumes in the setting of IBR are lacking. Therefore, many patients who have had IBR receive PMRT to target volumes similar to conventional simulator-based whole breast irradiation. The aim of this paper is to describe delineation guidelines for PMRT after implant-based IBR based on a thorough understanding of the surgical procedures, disease stage, patterns of recurrence and radiation techniques. They are based on a consensus endorsed by a global multidisciplinary group of breast cancer experts.

The individualized Goals of Care Discussion Guide: A simple tool to empower patients with metastatic breast cancer

11622

Background: Individualized treatment planning is a critical part of quality cancer care, but how best to achieve this for patients with metastatic breast cancer (MBC) is unclear. We evaluated the feasibility, acceptability and impact of using a simple and scalable “Individualized Goals of Care Discussion Guide” (IGCDG) to facilitate patient-provider communication at the time of treatment decisions. Methods: We developed the IGCDG based on structured interviews with MBC patients and input from experts in cancer care, decision sciences, psychology and palliative care. We then conducted a single arm feasibility trial among patients with newly diagnosed or progressive MBC. Prior to clinic, patients received the IGCDG, an 8-page MBC informational brochure and 1-page questionnaire regarding treatment preferences, personal goals and priorities for care planning. The completed questionnaire was provided to the oncology team at the patient’s visit. Pre and post assessment included the Distress Thermometer (DT), Patient Satisfaction with Cancer Care Scale and the Control Preferences Scale. Feasibility was defined as: 1) accrual of > 50%, 2) attrition rate < 32%, and 3) < 50% of patients experiencing increased distress following the intervention. Results: Among 60 eligible patients, 42 participated (70% accrual), 40 completed all surveys (2% attrition), and only 7 (18%) reported increased distress. Mean age was 57 (range 31 – 79), 85% were white, 7% black, 5% Hispanic, 66% were college graduates, and 40% reported high baseline distress (DT > 4). Patient priorities for discussion included cancer directed therapy (70%), symptom management (70%), and prognosis/planning ahead (60%). At 2-month follow-up, 53% reported decreased distress compared to baseline. Satisfaction with cancer care was high at baseline and follow-up. Most patients preferred shared decision making (77%), and 79% reported decision roles concordant with preferences. Overall, 72% of participants found the IGCDG helpful, 93% found the questionnaire easy to complete, and 44% felt it improved communication with their doctor (49% unsure). Conclusions: Administration of the Individualized Goals of Care Discussion Guide is feasible and provides patients with MBC an opportunity to define their goals of care and priorities for discussion in clinic. Clinical trial information: NCT03375827.
