Characteristics of adolescent and young adult patients with cancer receiving home-based palliative care: A retrospective study at a single center.

Adolescents and young adults (AYA) with cancer require highly individualized, age-specific end-of-life care. This study identified the characteristics of AYA patients with cancer receiving home-based palliative care and explored their unique needs and challenges compared with other age groups. This retrospective cohort study analyzed the medical records of AYA patients with cancer to compare home-based palliative care characteristics with those of older age groups. The study included 81 AYA patients with cancer aged 16-39years who had received home palliative care at a single institution from 2013 to 2023. They were compared with 5,017 patients with cancer aged 40years and older. Patient background, duration of home end-of-life care, sedation, and association with social factors were examined retrospectively from medical records. The median age of AYA patients with cancer was 34years; 65.4% were female. The primary cancer sites were gastrointestinal (34.6%) and thoracic (23.5%), with 80.0% at Stage IV. The median home care duration was 28.5days, shorter than that for older patients (40days) (p < 0.0001). Home care rates were similar between AYA and older patients (82.4% vs. 79.9%, p = 0.16). Sedation was more common in the 30-39 age group than in the 16-29 group (33.3% vs. 6.3%, p = 0.049). AYA patients with cancer achieved a high rate of end-of-life care at home, although their duration of home care was shorter. The characteristics of home care varied depending on the primary site and age, highlighting the importance of creating highly individualized care plans.

Melanoma in Adolescents and Young Adults (AYAs): An Italian Multi-Centric Retrospective Experience

Background: Melanoma is currently the most prevalent malignant neoplasm among adults and represents the second most common cancer in both sexes among individuals aged 0 to 39 years. This retrospective multicenter study delves into the distinctive clinical, anamnestic, histopathologic, and prognostic attributes of melanoma in Adolescent and Young Adults (AYA), defined as patients diagnosed at ≤40 years, across four Italian centers. Methods: Through a computer-based review of clinical records from 1 January 2010 to 30 September 2023, AYA melanomas were contrasted with non-AYA melanomas (&gt;40 years) among 1452 patients. Data on demographics, melanoma localization, histological type, Breslow thickness, ulceration, and sentinel lymph node (SLN) biopsy status were meticulously collected and analyzed. Results: Our analysis revealed a female predominance in the AYA group and a male predominance in the non-AYA group, with significant differences in anatomical localization and histological types between the two. AYA melanomas showed nearly equal trunk and limb involvement, contrasting with the trunk predominance in non-AYA melanomas. While Breslow thickness was similar across both groups, the presence of ulceration and total number of nevi showed no significant difference. Survival analysis indicated a marginally higher Disease-Free Survival (DFS) in AYA patients compared to non-AYA patients, without a significant difference in Overall Survival (OS). Conclusions: This study highlights demographic and clinical distinctions between AYA and non-AYA melanoma patients, underscoring the need for tailored follow-up and treatment strategies. Despite these insights, the heterogeneity of melanoma among young adults calls for further research, including genetic analyses, to fully understand this unique melanoma subgroup. Indeed, AYA melanoma patients could represent a different and specific target for both follow-up and treatments.

A Randomized Controlled Trial of a Digital Intervention to Improve the Sexual Health of Adolescent and Young Adult Male Emergency Department Patients

PurposeTo assess implementation outcomes and potential efficacy of a user-informed, theory-based digital health intervention developed to improve adolescent and young adult (AYA) male sexual health. MethodsWe conducted a pilot randomized controlled trial of sexually active male emergency department (ED) patients aged 14–21 years. Participants were randomized to the intervention (Dr. Eric, Emergency Room Interventions to improve Care) or usual care. Dr. Eric consists of an ED-based sexual health app followed by 3 months of interactive text messages. We assessed the feasibility, adoption, and fidelity among users. Condom use, defined as the number of sexual encounters with condoms divided by the total number of sexual encounters over the past 4 weeks, was the primary efficacy outcome. ResultsWe enrolled 119 patients; mean age was 17.9 years, 87% were Hispanic, and half used condoms at last intercourse. Dr. Eric demonstrated feasibility, with high rates of consent (86.2%) and follow-up (81.5%). Intervention participants found Dr. Eric acceptable, liking (86.2%) and recommending (87.9%) the program. 98% of intervention participants interacted with all five app modules; one-quarter opted out of text messaging. At 6-week follow-up, the intervention group more often used a condom compared to the control group [OR 3.57, 95% confidence interval (1.93, 6.60)], p < .001]; however, this significant difference did not sustain at 13 weeks. DiscussionDr. Eric was feasible to deliver and acceptable to male AYA patients. To our knowledge, Dr. Eric is the first intervention to demonstrate evidence of short-term efficacy for improving condom use among male AYA in the ED.

Financial toxicity and unmet social needs in adolescents and young adults (AYA) with cancer.

13 Background: Cancer incidence is rising in adolescents and young adults (AYA) (age 18-39), a population that faces durable financial challenges during and after treatment. Although AYA cancer survivors face unique risks for poor outcomes due to financial toxicity (FT), best practices for FT and social needs screening (i.e. food, housing, transportation insecurity) are unknown. Further, the relationship between FT and social needs is largely unexplored in AYA. Methods: A FT and social needs screening quality improvement project was conducted at a comprehensive cancer center. The Comprehensive Score for Financial Toxicity (COST) assessed FT, and patients reported unmet social needs and treatment payment methods. Quality of life (QOL) was assessed via a visual analog scale. Multivariate linear and logistic regression tested for associations with FT and unmet social needs, adjusting for demographic and clinical characteristics. Results: Of 70,983 requests, 38,249 patients completed the screening (54% response rate): 2,519 were AYA. Mean age of AYA was 33.7 years (SD 4.7), and most (65%) were non-Hispanic white. Disease sites included 41% breast, 20% gastrointestinal, and 19% gynecologic. Over one-half (54%) had active cancer treatment (chemotherapy, radiation, or surgery) within 120 days of assessment. Mean COST was 23.2 (SD 10.8; 0-44, with lower scores indicating worse FT), and 54% had COST &lt;26, suggesting FT. Racial/ethnic minority patients (β -4.37, p&lt;0.001) and those who had recent treatment (β -3.21, p&lt;0.001) had worse FT. Of those who screened positive for FT, only 44% accepted a referral for financial assistance. About one-quarter of the sample (28%) were unable to afford at least one social need, with 16% facing housing, 14% transportation, and 13% food insecurity. Patients who are a racial/ethnic minority (OR 2.98, 95% CI 2.35-3.79, p&lt;0.001) and those with metastatic disease (OR 2.45, 95% CI 1.10-5.45, p=0.028) were more likely to have at least one unmet social need. One-quarter of the sample (24%) used at least some of their savings to pay for treatment, with 7% reporting they did not have any savings. 25% borrowed money or took on new loans to pay for treatment: of those, 58% borrowed from friends/family. 10% did not have enough money for medications, and 7% took less medications than prescribed due to cost. Mean QOL was 7.3 [(SD 1.8) 0 “as bad as it can be”-10 “as good as it can be”]. Increased FT was associated with reduced QOL (β -0.10, p&lt;0.001), using more savings to pay for treatment (β 0.52, p&lt;0.001), and taking less medications due to cost (β 0.01, p&lt;0.001). Conclusions: Routine FT and social needs screening is feasible for AYA patients and uncovers high rates of FT and unmet social needs. Given lower QOL and decreased adherence to treatment associated with FT, future research should focus on interventions to support the specific needs of AYA and increase acceptance of financial assistance and navigation.

EASIX and m-EASIX predict CRS and ICANS in pediatric and AYA patients after CD19-CAR T-cell therapy

AbstractCytokine release syndrome (CRS) and immune effector cell–associated neurotoxicity syndrome (ICANS) are complications of CD19-directed chimeric antigen receptor (CD19-CAR) T-cell therapy. The Endothelial Activation and Stress Index (EASIX) and modified EASIX (m-EASIX) scores have been retrospectively proven to be predictive of CRS and ICANS in adult CAR T-cell recipients. However, these scores have not been evaluated in pediatric cohorts. We retrospectively report on 76 pediatric and adolescent and young adult (AYA) patients with relapsed/refractory B-cell acute lymphoblastic leukemia treated with CD19-CAR T cells at St. Jude Children’s Research Hospital or John’s Hopkins Hospital. Data included patient, disease, and treatment characteristics. EASIX and m-EASIX scores were calculated at days –5 before, 0, and +3 after CAR T-cell infusion. CRS and ICANS occurred in 47 and 17 patients, respectively. At all evaluated time points, the median EASIX scores were higher for patients who developed severe CRS and any grade ICANS, and the median m-EASIX scores were higher in patients who developed severe CRS and severe ICANS than those with no/mild CRS/ICANS. Receiver operating characteristic curve analysis showed that both scores were strong predictors of CRS, especially severe CRS, at all time points. Any grade and severe ICANS were best predicted by both scores at day +3. m-EASIX uniformly outperformed EASIX, except for predicting any grade ICANS. Our results validate the potential utility of EASIX and m-EASIX scores for predicting CAR T-cell–related complications for pediatric and AYA patients.

“Aiming at a moving target”—The daily life experiences of adolescents and young adults with a low-grade glioma

Abstract Background Low-grade gliomas (LGG) are among the most frequently occurring tumors in adolescent and young adult (AYA) patients (aged 18–39 years old at primary diagnosis). These tumors have a variable prognosis, presenting challenges for patients in shaping their future. This study aimed to identify the age-specific experiences and needs of AYA patients with LGG in their daily lives. Methods In-depth interviews were conducted with AYA patients diagnosed with LGG. Thematic analysis was performed to derive the age-specific codes, looking for overarching themes and sub-themes. Results Sixteen patients participated in this study. The cognitive symptoms of the disease (including difficulty concentrating, memory issues, and speech problems) are invisible to others but caused significant disruptions in many domains that were particularly important to AYA patients (eg, employment, family life, and autonomy). Additionally, the uncertainty regarding their life expectancy led to difficulties in making decisions about the future. They also perceived a lack of control over their future and the time they had left. Conclusions LGG have a significant impact on AYA patients. However, this impact is not fully understood by others close to them. The results highlight the importance of providing these patients with appropriate peer support, interventions tailored to both their disease and life phase, utilizing a multidisciplinary approach, and maintaining a focus on long-term support for these patients. It is crucial to provide AYA care for these patients within the neurology department, as LGG involve both tumor- and age-specific problems.

Abatement of the Survival Cliff in Older Adolescents and Young Adults with Acute Lymphoblastic Leukemia and Lymphoblastic Lymphoma in the United States.

Purpose: In 2018, a "survival cliff" in the United States was identified among older adolescent and young adult (AYA) patients with acute lymphoblastic leukemia (ALL) and lymphoblastic lymphoma (LBL). This study reassessed the cliff and associated putative causes. Methods: Survival data were obtained using the U.S. Surveillance Research Program, National Cancer Institute (NCI) SEER 22 Registries. Accrual data on cancer treatment trials conducted by the NCI cooperative groups and NCI-designated cancer centers were obtained from the NCI Cancer Therapy Evaluation Program. Trend and average percent changes and statistical significances were identified with the NCI Joinpoint Regression Program. Results: A previous cliff-like decrement in the survival of 17- to 20-year-olds is no longer apparent, overall and in all racial and ethnic groups. The "survival cliff" age range was coincident with a clinical trial accrual cliff, and both diminished when more clinical trials were available to, and participated in by, young adult patients. Older AYA patients of ages 30-39 had minimal improvement in clinical trial accrual and least survival gain among the AYA age group. Conclusion: The survival cliff has abated, resulting in thousands of fewer premature deaths and tens of thousands of years of life saved-a remarkable achievement. The survival improvement may be attributed to improved clinical trial availability for and recruitment and participation of AYAs on treatment trials, application of pediatric-inspired ALL treatment regimens to AYAs, expanded national health insurance for -18 to 25 year olds, improved AYA cancer services, and a national focus on AYA oncology.

Outcome of adolescents and young adult acute myeloid leukemia patients compared with middle-aged patients: A single centre retrospective experience

Adult acute myeloid leukemia (AML) patients under the age of 60 often receive similar intensive treatments, while outcomes between the adolescent and young adult (AYA) age group (18−39) and middle-aged adults (40–60 years) were seldom reported. We aim to study the characteristics and outcomes of AYA patients in comparison to middle-aged adults. A retrospective analysis was performed on AYA patients treated at Princess Margaret Cancer Center between 2008 and 2018. The primary outcomes include overall survival (OS), cumulative incidence of relapse (CIR), and non-relapse mortality (NRM).A total of 174 AYA patients and 176 middle-aged patients were included, with propensity score matching adjusting for potential major confounders. Comparing AYA and middle-aged patients, 5-year OS rates were similar at 54.6 % vs. 56.5 % (p=0.91), CIR rates at 29.5 % vs. 23.1 % (p=0.31), and similar NRM rates. Notably, non-transplanted AYA patients had a significantly higher CIR (39.8 %) compared to middle-aged patients (19.6 %) (p=0.0324), with more primary refractory/early relapsing disease. An observed trend toward improved OS in AYA patients post-2015 coincided with FLAG-IDA and haploidentical transplant implementations.In conclusion, the study suggests that AYA patients, particularly those not undergoing transplantation, may benefit from more intensive treatment strategies, emphasizing the need for tailored approaches in this age group.

Ten‐year follow‐up of outcomes, patterns of care, and psychosocial burden in adolescent and young adult patients with bone sarcomas from a large cohort in a low‐income and middle‐income country

AbstractBackgroundThe care of adolescents and young adults (AYAs) with bone sarcomas involves unique challenges. The objectives of this study were to identify challenges and evaluate long‐term outcomes of these patients from India who received treatment with novel protocols.MethodsThis prospective cohort study included AYA patients (aged 15–39 years) with osteosarcoma and Ewing sarcoma (ES), who were treated uniformly at the authors' institute using unique protocols (OGS‐12 and EFT‐2001) from 2011 to 2021 and from 2013 to 2018, respectively.ResultsThe cohorts included 688 of 748 (91.9%) treatment‐naive AYA patients with osteosarcoma and 126 of 142 (88.7%) treatment‐naive AYA patients with ES. Among 481 of 561 patients (85.7%) who had nonmetastatic osteosarcoma treated according to protocol, at a median follow‐up of 59.7 months, the 5‐year event‐free survival (5‐EFS) rate was 58.6% (95% confidence interval, 54.1%–63.5%) and for 142 patients (20.6%) who had metastatic osteosarcoma, the 5‐EFS rate was 18.7%. The 5‐EFS rate was 66.4% and 21.9% for 104 patients (73%) with nonmetastatic ES and 38 patients (27%) with metastatic ES, respectively. Treatment‐naive patients had better outcomes, similar to compliance in the form of protocol completion (hazard ratio, 1.93 [p = .0043] and 2.66 [p &lt; .0001], respectively. Only 230 of 377 (61.0%) male patients and 10 of 134 (7.4%) female patients reached out to fertility specialists. In addition, 17 of 161 (10.6%) eligible male survivors and 14 of 61 (22.9%) eligible female survivors got married posttreatment. Furthermore, 14 of 17 (82.4%) males and 14 of 14 (100%) females conceived. Among 311 patients who were working or attending school during diagnosis, greater than 90% had interruptions.ConclusionsHomogenous treatment with the OGS‐12 and EFT‐2001 protocols resulted in internationally comparable long‐term outcomes in the cohorts with nonmetastatic and metastatic AYA bone sarcomas. Treatment compliance, timely referral to sarcoma reference centers (avoiding prior inadvertent treatment), and streamlining fertility‐preservation practices constitute unmet needs that demand prioritization.

Clinical Characteristics and Prognosis of Early-Onset Hepatocellular Carcinoma: A Retrospective Cohort Study Based on Population Data.

The incidence of young patients diagnosed with hepatocellular carcinoma (HCC) is projected to rise. This study aimed to investigate the distinctive characteristics of adolescent and young adult (AYA) patients with HCC and identify the risk factors that impact their survival. This study included 1005 AYA patients and 55,435 older adult (OA) patients with HCC, using data from the Surveillance, Epidemiology, and End Results database. Propensity score matching was used to adjust for baseline differences in patient characteristics. The Kaplan-Meier curve and log-rank test are utilized to compare the overall survival between the two groups. The Cox proportional hazards regression model was used for subgroup analysis to identify risk factors for overall survival in AYA patients. AYA patients exhibited a higher proportion of advanced clinical stage (49.15% vs 37.57%, P < 0.001) and fibrolamellar hepatocellular carcinoma (14.13% vs 0.09%, P < 0.001), but a lower incidence of alpha-fetoprotein positivity (32.04% vs 45.32%, P < 0.001) and cirrhosis (8.86% vs 18.32%, P < 0.001). The subgroup analysis results indicated that AYA patients had a more favorable prognosis than OA patients in most subgroups. Undifferentiated carcinoma emerged as the predominant risk factor for AYA patients (Hazard Ratio [HR], 6.08 [2.53-14.62]), whereas partial hepatectomy was determined to be the most advantageous factor (HR, 0.29 [0.23-0.37]). AYA patients with HCC exhibit more aggressive characteristics but demonstrate a better prognosis compared to the OA group, necessitating personalized surveillance and treatment.

Immunophenotypic Characteristics and Cytogenetic Analysis of Adolescent and Young Adult B-Cell Acute Lymphoblastic Leukemia: Correlations With Clinicopathological Parameters.

Introduction Acute lymphoblastic leukemia (ALL) has suboptimal survival rates for adolescents and young adults (AYA) as compared to children. Very limited studies have been conducted on AYA patients in India. This study aimed to identify the cytogenetic and immunophenotype characteristics of B-cell ALL (B-ALL) in AYA patients and determine its correlation with clinicopathological parameters in the Southern India region. Method The study was a prospective study conducted for three years, from June 2019 to May 2022, in India. Newly diagnosed 90 patients with AYA (13-40 years) ALL were recruited. A B-ALL diagnosis was made based on morphology with cytochemical stains and immunophenotype by flow cytometry (FCM). Cytogenetic analysis was also performed using karyotyping and fluorescent in situ hybridization to identify chromosomal aberrations. The cytogenetics results were correlated with immunophenotyping and clinicopathological characteristics. Variables were analyzed using the Mann-Whitney U test and Chi-square test using IBM SPSS Statistics for Windows, Version 20.0 (Released 2011; IBM Corp., Armonk, NY, USA). Results The mean age was 22.68 ± 8.06 years. It was observed that the most common structural chromosomal abnormality for AYA was t(9;22) in 14 (15%) cases, followed by 6q deletions in seven (8%) cases, t(1;19) in four (4%) cases, and t(12;17) and t(6;14) in two (2%) cases each. In addition, t(3;12), t(2;11), t(12;21), t(1;9), t(2;12), and t(X;10) were found in one (1%) case each. The most common numerical abnormality was hyperdiploidy (15; 17%), followed by hypodiploidy (10; 11%). Further, myeloid antigen expression of CD33 was the most common aberrantly expressed marker found in 20 (28%) cases, followed by CD15 in three cases (5%), CD13 in three (4%) cases, and CD11b in two (3%) cases. It was also observed that in Ph+ve cases, CD33 and CD13 were most commonly expressed in three (33%) and two (17%) cases, respectively. In contrast, in Ph-ve patients, their expressions were lesser at 17 (27%) and one (2%) cases, respectively. In addition, leukemia-associated immunophenotype pattern (LAIP) markers CD44 6 (86%) and CD123 5 (55%) were also found to be significantly associated with Ph+ve, whereas their values in the Ph-ve group were lesser at 25 (42%) and 9 (17%), respectively. Our data also showed that older age wassignificantly associated with Ph+ve with a median age of 30 years (p = 0.012). In comparison, the median age of Ph-ve was only 21 years. Conclusion Our study established that the incidence of cytogenetic abnormalities for AYA was consistent with previously reported data. This study reaffirms that Ph+ve cases have significant associations with MyAg (CD13), LAIP (CD123 and CD44), and older age for the South Indian population.

Diagnostic genomic analysis is prognostic in AYA patients with ALL treated on an MRD-stratified pediatric protocol

AbstractOver the last decade, next-generation sequencing has enabled classification of multiple new recurrent genomic drivers of acute lymphoblastic leukemia (ALL). The aim of this study was to describe the genomic drivers of ALL in an adolescent and young adult (AYA) cohort (ALL06; target age, 15-39 years; recruited age, 16.6-39 years), treated uniformly on a pediatric-inspired protocol (the Australasian Leukaemia and Lymphoma Group ALL06 study). ALL06 assessed the safety and efficacy of adapting a pediatric chemotherapy protocol in older patients. Genomic risk classification of patients with B-cell ALL (B-ALL) and T-cell ALL (T-ALL) enrolled to the study was based on the use of multiple assays: messenger RNA sequencing, multiplex ligation-dependent probe amplification, immunophenotyping, and cytogenetics. Using this approach, 36 of 40 (90%) patients with B-ALL and 13 of 17 (76.5%) patients with T-ALL were classified according to genomic risk. A strong correlation existed between adverse genomic risk and minimal residual disease (MRD) at the end of consolidation, translating to inferior overall and relapse free survival. Patients with adverse risk genomics who achieved negative MRD status had improved responses compared with those with persistent MRD. Patients with standard-risk genomics had excellent responses regardless of MRD status. This is, to our knowledge, the first report of the impact of genomics in an individual cohort of AYA patients treated on a single protocol. These data argue strongly for incorporation of a genomic risk classification into future ALL treatment paradigms at the time of diagnosis, and also for the rigorous assessment of risk assignments in a group of patients who are not children and not older adults. This trial was registered at https://anzctr.org.au/ as #ACTRN12611000814976.

Smartphone-based distress screening, information provision, and psychotherapy for reducing psychological distress among AYA cancer survivors: protocol for a fully decentralized multicenter randomized controlled clinical trial.

Fear of cancer recurrence (FCR) is a common and distressing condition among adolescents and young adults (AYAs). This study aims to investigate the efficacy of digital interventions, including distress screening-based information provision and smartphone problem-solving therapy, on common psychological distress, especially FCR, in AYA patients with cancer. Participants will be 224 AYA outpatients with cancer aged 15-39years who will be randomly assigned to either an 8-week smartphone-based intervention or a waitlist control group. This intervention includes smartphone-based distress screening, information provision, and psychotherapy (problem-solving therapy). The primary endpoint will be the Fear of Cancer Recurrence Inventory-Short Form score at week 8. This study will be conducted as a fully decentralized, randomized, and multicenter trial. The study protocol was approved by the Institutional Review Board of Nagoya City University on 19 April 2024 (ID: 46-23-0005). Trial registration: UMIN-CTR: UMIN000054583.

Treatment of Medulloblastoma in the Adolescent and Young Adult Population: A Systematic Review.

Medulloblastoma is the most frequent high-grade tumor of the central nervous system in children but accounts for less than 1% of these tumors in adults. Adolescent and young adult (AYA) patients are between both age groups, and different approaches are used to treat medulloblastoma in this population. We performed a systematic review of studies published between 2007 and 2023 that reported treatment approaches and survival data of AYA patients with medulloblastoma, defined as 15 to 39 years of age at diagnosis. Due to the heterogeneity of data, a meta-analysis was not possible. Except for the omission of chemotherapy after radiotherapy in a few adult studies, the treatment backbone is very similar between studies starting enrolment during childhood and older adolescence or adulthood. Despite indications for a higher rate of early treatment termination due to toxicity in adults, survival data remain comparable between studies starting enrolment earlier or later in life. However, molecular subtyping was missing in most studies, so the survival data must be interpreted cautiously. Nevertheless, pediatric-inspired strategies in the AYA population are feasible, but individual dose adjustments may be necessary during treatment and should be considered upfront. Collaborative studies investigating the best treatment approach for medulloblastoma in the AYA population are needed in the future.

Allogeneic stem cell transplant with TBI-based myeloablative conditioning in adolescents and young adults with Philadelphia chromosome-negative ALL treated with pediatric protocols

To investigate the safety of total body irradiation-based myeloablative conditioning (TBI-MAC) in adolescent and young adult (AYA) Philadelphia chromosome (Ph)-negative acute lymphoblastic leukemia (ALL) patients treated with pediatric protocols, treatment outcomes of 106 AYA patients aged 16–39 years old undergoing allogeneic stem cell transplant (allo-SCT) with TBI-MAC in the first remission were compared according to chemotherapy types before transplant. Pediatric and adult protocols were used in 56 and 50 of the patients, respectively. The cumulative incidence (CI) of non-relapse mortality (NRM) and the overall survival (OS) rates were not significantly different between the pediatric-protocol and adult-protocol group (NRM: 4 % vs. 14 % at five years post-transplant, respectively, p = 0.26; OS: 81 % vs. 66 %, respectively, p = 0.14). Multivariate analysis for NRM revealed that a performance status >0 (hazard ratio [HR] = 4.8) and transplant due to chemotherapy toxicities (HR = 3.5) were independent risk factors, but a pediatric protocol was not (HR = 0.48). The CI of NRM and the OS rates were also similar among patients aged over 24 years old. These findings suggested that conventional allo-SCT with TBI-MAC can be performed without increasing NRM in AYA patients with Ph-negative ALL even after pediatric protocols.

Stereotactic Ablative Radiation Therapy (SABR) for Adolescent and Young Adult Malignancies.

There are limited studies examining local control (LC) and overall survival (OS) following stereotactic ablative radiation therapy (SABR) for adolescent and young adult (AYA) populations/histologies with local recurrences or metastatic disease. The RSSearch® Patient Registry, an international SABR registry, was evaluated for AYA patients treated with SABR. AYA patients with adult histologies/primaries were excluded. Kaplan-Meier analyses were employed to characterize LC and OS following SABR. Potential prognostic factors were assessed with log-rank tests for initial univariate analysis (UVA). For multivariate analyses (MVA), a Cox proportional hazards multivariate model was utilized. A total of 19 AYA patients with 39 lesions treated with SABR were identified and included in the analysis. Four lesions (10.3%) were treated with SABR for primary tumor recurrence and 35 lesions were treated for metastatic disease. The median patient age was 34 years (range: 16-39 years). Common lesion locations included lung (11 lesions; 28.2%), non-spinal bone (nine lesions; 23.1%), and spine (six lesions; 15.4%). The median biological effective dose (BED10) was 61.5 Gy (range: 26.4-180). One-year LC and OS following SABR were 77.7% (95% CI: 58.5-88.7) and 72.7% (95% CI: 46.3-87.6), respectively. On UVA, BED10 ≥ 60 Gy was associated with superior one-year LC (94.4% vs. 47.6%; p<0.0001) as were sarcoma primaries (two-year LC: 92.3% vs. 42.2%;p = 0.0002). Central nervous system (CNS) primaries had significantly poorer one-year LC (20% vs 87.5%; p<0.0001) as well as spinal metastases (33.3% vs. 87.0%; p<0.0001). On MVA, BED10 < 60 Gy was associated with inferior LC (hazard ratio (HR) = 5.51;p = 0.01) with sarcoma primaries associated with superior LC (HR = 0.04;p = 0.008). SABR with BED10 ≥ 60 Gy resulted in durable LC for AYA patients, particularly those with sarcoma primaries, though poor outcomes were noted in metastatic CNS malignancies.

Racial Disparities in Cancer Stage at Diagnosis and Survival for Adolescents and Young Adults

There are limited studies assessing stage at diagnosis and risk of death among all 5 federally defined races in the US among adolescent and young adult (AYA) patients with cancer. To identify racial disparities in stage at diagnosis and survival among AYA patients with cancer. This retrospective cohort study used data from a US national hospital-based oncology database on AYA patients, aged 15 to 39 years, with the 10 deadliest cancers among AYA patients who received a diagnosis from January 1, 2004, to December 31, 2017, with 6 months or more of follow-up. Analyses by race were categorized by the 5 federally defined races in the US: American Indian or Alaska Native, Asian, Black, Native Hawaiian or Other Pacific Islander, and non-Hispanic White (hereafter, White). White patients served as the majority reference group. Statistical analysis was performed from November 2022 to September 2023. The primary end points were late stage at diagnosis (logistic regression with adjusted odds ratios [AORs] and 95% CIs) and overall survival (log-rank tests and Cox proportional hazards regression with adjusted hazard ratios [AHRs] and 95% CIs). A total of 291 899 AYA patients (median age, 33 years [IQR, 28-37 years]; 186 549 female patients [64%]; 189 812 [65%] with stage I or II cancers) were evaluated. The cohort included 1457 American Indian or Alaska Native patients (1%), 8412 Asian patients (3%), 40 851 Black patients (14%), 987 Native Hawaiian or Other Pacific Islander patients (0.3%), and 240 192 White patients (82%). Cancers included breast (n = 79 195 [27%]), lymphoma (n = 45 500 [16%]), melanoma (n = 36 724 [13%]), testis (n = 31 413 [11%]), central nervous system (n = 26 070 [9%]), colon or rectum (n = 22 545 [8%]), cervix (n = 20 923 [7%]), sarcoma (n = 14 951 [5%]), ovary (n = 8982 [3%]), and lung (n = 5596 [2%]). Risk of late-stage diagnosis was higher for Asian (AOR, 1.20; 95% CI, 1.14-1.26), Black (AOR, 1.40; 95% CI, 1.36-1.43), and Native Hawaiian or Other Pacific Islander (AOR, 1.34; 95% CI, 1.16-1.55) patients compared with White patients. Overall survival differed by race for all cancer sites, except cancers of the central nervous system and ovary. Risk of death was higher for American Indian or Alaska Native (AHR, 1.15; 95% CI, 1.02-1.30), Black (AHR, 1.22; 95% CI, 1.19-1.26), and Native Hawaiian or Other Pacific Islander (AHR, 1.25; 95% CI, 1.09-1.44) patients but lower for Asian patients (AHR, 0.90; 95% CI, 0.85-0.95) compared with White patients. This cohort study of AYA patients suggests that stage at diagnosis and survival varied across races for the 10 deadliest AYA cancers. These results support the need for tailored interventions and informed public policy to achieve cancer care equity for all races.

Harmonization of the Upfront Osteosarcoma Treatment Paradigm for Adolescents and Young Adults.

Limited guidance exists on streamlining cancer therapy for adolescent and young adult (AYA) patients 15-39 years of age, as much of the current data are extrapolated from pediatric or adult counterparts and can differ significantly between the two care models. Harmonization of standard treatment approaches has the potential to improve outcomes and establish a foundation for the development of future clinical trials. We present our experience harmonizing treatment and supportive care regimens for AYA patients with osteosarcoma receiving treatment with methotrexate, doxorubicin, and cisplatin (MAP) therapy on the pediatric and adult sarcoma services at the Memorial Sloan Kettering Cancer Center.

Temporal trends of adolescents and young adults (AYA) with gynecologic malignancy in the United States

In this retrospective cohort study examining 13,763,447 patients with 16 different malignancies, including 1,232,841 patients with five gynecologic malignancies (uterus [n = 690,590], ovary [n = 276,812], cervix [n = 166,779], vulva [n = 81,575], and vagina [n = 17,085]), identified in the Commission-on-Cancer’s National Cancer Database from 2004 to 2020, cervical cancer (25.3 %) had the highest rate of adolescent and young adult (AYA) patients among 27 gender-stratified cancer groups (25.3%). There were 8 groups that the annual rates of AYA patients statistically increased during the study period at a P < .05 level, of which 7 (87.5 %) groups were for female malignancies. Among these 7 female malignancies, the annual percentage rate increase in AYA patients was largest for colorectal cancer (4.1 %, 95 % confidence interval 3.6–4.6), followed by malignancies in the ovary (3.1 %, 95 % confidence interval 1.6–4.5 in 2014–2020), pancreas (2.1 %, 95 % confidence interval 1.0–3.2), uterus (1.2 %, 95 % confidence interval 0.3–2.0 in 2013–2020), breast (0.8 %, 95 % confidence interval 0.2–1.4 in 2012–2020), cervix (0.8 %, 95 % confidence interval 0.2–1.5 in 2011–2020), and kidney (0.4 %, 95 % confidence interval 0.1–0.9). In conclusion, these data suggested that proportion of cancers attributable to AYA patients is increasing in several obesity-related female malignancies and in the three most common gynecologic malignancies.

Feasibility and Clinical Utility of Patient-Reported Outcome Measurement Information System-29 in a Newly Established Adolescent and Young Adult Oncology Program.

Purpose: Despite improvements in survival, adolescent and young adult (AYA) oncology patients are at high risk for experiencing negative health-related quality of life (HRQOL) outcomes. AYA cancer programs have attempted to develop assessment tools to identify areas of need. We aimed to demonstrate the feasibility/utility of the Patient-Reported Outcome Measurement Information System®-29 (PROMIS®-29) within an AYA oncology program clinic. Methods: AYA patients were referred by oncologists to the AYA oncology program at Prisma Health. The PROMIS-29 v2.0 survey was administered to AYAs at point of care. Feasibility of distribution and completion rate of surveys were determined. PROMIS surveys were self-reported and subsequently scored using standardized methods. The domains assessed included physical function, anxiety, depression, fatigue, sleep disturbance, ability to participate in social roles/activities, pain interference, and pain intensity. Qualitative descriptions of AYA care delivery based on survey responses at the patient level and programmatic level are also presented. Results: Between May 2017 and 2019, 134 AYAs who were newly diagnosed or in treatment completed the survey. Distribution and completion rates for the PROMIS-29 were both 100%, and meaningful changes in program-level services were implemented as a result of PROMIS-29 score patterns. Within the entire cohort, T-scores for anxiety, fatigue, and physical function reached clinically relevant thresholds. Conclusion: PROMIS offers a feasible opportunity for AYA programs to measure clinically useful HRQOL outcomes in AYAs. The survey can be used to deliver real-time AYA care to recently diagnosed and in-treatment AYAs and make programmatic changes within AYA oncology programs.
