Harnessing multi-source data for individualized care in Hodgkin Lymphoma. Blood Rev 2024; 65:101170. [PMID: 38290895 DOI: 10.1016/j.blre.2024.101170] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2023] [Revised: 12/22/2023] [Accepted: 01/11/2024] [Indexed: 02/01/2024]
Abstract
Hodgkin lymphoma is a rare, but highly curative form of cancer, primarily afflicting adolescents and young adults. Despite multiple seminal trials over the past twenty years, there is no single consensus-based treatment approach beyond use of multi-agency chemotherapy with curative intent. The use of radiation continues to be debated in early-stage disease, as part of combined modality treatment, as well as in salvage, as an important form of consolidation. While short-term disease outcomes have varied little across these different approaches across both early and advanced stage disease, the potential risk of severe, longer-term risk has varied considerably. Over the past decade novel therapeutics have been employed in the retrieval setting in preparation to and as consolidation after autologous stem cell transplant. More recently, these novel therapeutics have moved to the frontline setting, initially compared to standard-of-care treatment and later in a direct head-to-head comparison combined with multi-agent chemotherapy. In 2018, we established the HoLISTIC Consortium, bringing together disease and methods experts to develop clinical decision models based on individual patient data to guide providers, patients, and caregivers in decision-making. In this review, we detail the steps we followed to create the master database of individual patient data from patients treated over the past 20 years, using principles of data science. We then describe different methodological approaches we are taking to clinical decision making, beginning with clinical prediction tools at the time of diagnosis, to multi-state models, incorporating treatments and their response. Finally, we describe how simulation modeling can be used to estimate risks of late effects, based on cumulative exposure from frontline and salvage treatment. The resultant database and tools employed are dynamic with the expectation that they will be updated as better and more complete information becomes available.

Overall survival and causes of death in elderly patients with Hodgkin lymphoma: a Norwegian population-based case-control study. Haematologica 2024; 109:1403-1412. [PMID: 37881879 PMCID: PMC11063854 DOI: 10.3324/haematol.2023.283721] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/11/2023] [Accepted: 10/19/2023] [Indexed: 10/27/2023] Open
Abstract
Elderly Hodgkin lymphoma (HL) patients are poorly characterized and under-represented in studies. In this national population- based study, we investigated cause-specific survival using competing-risk analysis in elderly HL patients compared to the normal population. Patients ≥60 years of age diagnosed between 2000-2015 were identified by the Cancer Registry of Norway, and records were reviewed in detail and compared to data from the Norwegian Cause of Death Registry for patients and cancer-free controls. Of 492 patients, 81 (17%) were ineligible for treatment directed specifically towards HL, mostly because of an underlying other lymphoma entity, whereas 74 (15%) and 337 (69%) were treated with palliative or curative intent, respectively. Median overall survival in patients ineligible for assessment of HL-directed therapies was 0.5 years (95% Confidence Interval [CI]: 0.4-0.6), and for palliatively and curatively treated patients 0.8 (0.4-1.2) and 9.1 (7.5-10.7) years, respectively. After correction of discrepancies in registry data, with 359 deaths, 108 (30%) died of HL, the most common cause of death. In curatively treated patients, treatment-related mortality was 6.5% and the risk difference of dying from HL compared to controls was 28% (95% CI: 23-33%) after ten years. These numbers indicate disease control in a majority of elderly patients eligible for curative treatment, compared to risk differences for death from HL of 59% (48-71%) and 42% (31-53%) after ten years in the palliative and ineligible groups, respectively. There was an increased risk of dying from hematologic malignancies other than HL in all groups, but not from other competing causes of death, showing no excess mortality from long-term treatment complications.

Impact of Preexisting Heart Failure on Treatment and Outcomes in Older Patients With Hodgkin Lymphoma. JACC CardioOncol 2024; 6:200-213. [PMID: 38774008 PMCID: PMC11103040 DOI: 10.1016/j.jaccao.2024.02.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2023] [Revised: 01/31/2024] [Accepted: 02/02/2024] [Indexed: 05/24/2024] Open
Abstract
Background Older patients with Hodgkin lymphoma (HL) often have comorbid cardiovascular disease; however, the impact of pre-existing heart failure (HF) on the management and outcomes of HL is unknown. Objectives The aim of this study was to assess the prevalence of pre-existing HF in older patients with HL and its impact on treatment and outcomes. Methods Linked Surveillance, Epidemiology, and End Results (SEER) and Medicare data from 1999 to 2016 were used to identify patients 65 years and older with newly diagnosed HL. Pre-existing HF, comorbidities, and cancer treatment were ascertained from billing codes and cause-specific mortality from SEER. The associations between pre-existing HF and cancer treatment were estimated using multivariable logistic regression. Cause-specific Cox proportional hazards models adjusted for comorbidities and cancer treatment were used to estimate the association between pre-existing HF and cause-specific mortality. Results Among 3,348 patients (mean age 76 ± 7 years, 48.6% women) with newly diagnosed HL, pre-existing HF was present in 437 (13.1%). Pre-existing HF was associated with a lower likelihood of using anthracycline-based chemotherapy regimens (OR: 0.42; 95% CI: 0.29-0.60) and a higher likelihood of lymphoma mortality (HR: 1.25; 95% CI: 1.06-1.46) and cardiovascular mortality (HR: 2.57; 95% CI: 1.96-3.36) in models adjusted for comorbidities. One-year lymphoma mortality cumulative incidence was 37.4% (95% CI: 35.5%-39.5%) with pre-existing HF and 26.3% (95% CI: 25.0%-27.6%) without pre-existing HF. The cardioprotective medications dexrazoxane and liposomal doxorubicin were used in only 4.2% of patients. Conclusions Pre-existing HF in older patients with newly diagnosed HL is common and associated with higher 1-year mortality. Strategies are needed to improve lymphoma and cardiovascular outcomes in this high-risk population.

Long-term and short-term cardiovascular disease mortality among patients of 21 non-metastatic cancers. J Adv Res 2024:S2090-1232(24)00117-6. [PMID: 38537701 DOI: 10.1016/j.jare.2024.03.017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/21/2024] [Revised: 03/05/2024] [Accepted: 03/23/2024] [Indexed: 04/04/2024] Open
Abstract
INTRODUCTION Previous studies on cardiovascular disease (CVD) death risk in cancer patients mostly focused on overall cancer, age subgroups and single cancers. OBJECTIVES To assess the CVD death risk in non-metastatic cancer patients at 21 cancer sites. METHODS A total of 1,672,561 non-metastatic cancer patients from Surveillance, Epidemiology, and End Results (SEER) datebase (1975-2018) were included in this population-based study, with a median follow-up of 12·7 years. The risk of CVD deaths was assessed using proportions, competing-risk regression, absolute excess risks (AERs), and standardized mortality ratios (SMRs). RESULTS In patients with localized cancers, the proportion of CVD death and cumulative mortality from CVD in the high-competing risk group (14 of 21 unique cancers) surpassed that of primary neoplasm after cancer diagnosis. The SMRs and AERs of CVD were found higher in patients with non-metastatic cancer than the general US population (SMR 1·96 [95 %CI, 1·95-1·97]-19·85[95 %CI, 16·69-23·44]; AER 5·77-210·48), heart disease (SMR 1·94[95 %CI, 1·93-1·95]-19·25[95 %CI, 15·76-23·29]; AER 4·36-159·10) and cerebrovascular disease (SMR 2·05[95 %CI, 2·02-2·08]-24·71[95 %CI, 16·28-35·96]; AER 1·01-37·44) deaths. In the high-competing risk group, CVD-related SMR in patients with localized stage cancer increased with survival time but followed a reverse-dipper pattern in the low-competing risk group (7 of 21 cancers). The high-competing risk group had higher CVD-related death risks than the low-competing risk group. CONCLUSION The CVD death risk in patients with non-metastatic cancer varied by cancer stage, site and survival time. The risk of CVD mortality is higher in 14 out of 21 localized cancers (high-competing cancers). Targeted strategies for CVD management in non-metastatic cancer patients are needed.

Abstract
Hodgkin lymphoma (HL) is a rare type of B-cell malignancy with bimodal age distribution targeting young adults and elderly. Prognostic models are available to identify risk of recurrence and response to treatment. Currently, positron emission tomography scanning is most useful in optimizing therapy. Outcomes are generally excellent with standard chemotherapy or combined modality therapy. Balancing efficacy and the risk of late effects in Hodgkin lymphoma is essential, including early detection of potential complications. Incorporation of novel therapies such as brentuximab vedotin and checkpoint inhibitors are being explored in the frontline setting, having already demonstrated improved survival and tolerable toxicity in advanced HL. Furthermore, the addition of these agents have the potential to transform treatment paradigms for early-stage HL and may result in improved outcomes with decreased risks of late toxicities that continue to afflict long-term survivors. However, the patient population, sequencing, and combinations with cytotoxic chemotherapy all remain still standing questions as results of current and upcoming randomized trials are awaited. In this article, we discuss the current data on the approach to initial treatment of early-stage classical HL, review toxicity profiles, and examine upcoming novel therapy trials.

Abstract
There has been a renewed effort globally in the study of older Hodgkin lymphoma (HL) patients, generating a multitude of new data. For prognostication, advancing age, comorbidities, altered functional status, Hispanic ethnicity, and lack of dose intensity (especially without anthracycline) portend inferior survival. Geriatric assessments (GA), including activities of daily living (ADL) and comorbidities, should be objectively measured in all patients. In addition, proactive multidisciplinary medical management is recommended (eg, geriatrics, cardiology, primary care), and pre-phase therapy should be considered for most patients. Treatment for fit older HL patients should be given with curative intent, including anthracyclines, and bleomycin should be minimized (or avoided). Brentuximab vedotin given sequentially before and after doxorubicin, vinblastine, dacarbazine (AVD) chemotherapy for untreated patients is tolerable and effective, and frontline checkpoint inhibitor/AVD platforms are rapidly emerging. Therapy for patients who are unfit or frail, whether due to comorbidities and/or ADL loss, is less clear and should be individualized with consideration of attenuated anthracycline-based therapy versus lower-intensity regimens with inclusion of brentuximab vedotin +/- checkpoint inhibitors. For all patients, there should be clinical vigilance with close monitoring for treatment-related toxicities, including neurotoxicity, cardiopulmonary, and infectious complications. Finally, active surveillance for "postacute" complications 1 to 10 years post therapy, especially cardiac disease, is needed for cured patients. Altogether, therapy for older HL patients should include anthracycline-based therapy in most cases, and novel targeted agents should continue to be integrated into treatment paradigms, with more research needed on how best to utilize GAs for treatment decisions.

Abstract
Hodgkin lymphoma (HL) affects older and younger patients and includes multiple options for initial treatment. We sought to examine the decision processes of practicing oncologists caring for patients with newly diagnosed HL. Through semi-structured interviews, we explored their perspectives about treatment decisions. We completed thematic analysis using the Anderson Behavioral Model of Health Services framework to identify factors associated with initial decisions. We completed 22 interviews, grouping findings into contextual factors, individual characteristics, and physician preferences. Paternalism was widely cited, along with collaboration between community and academic colleagues. Participants used sequential therapy but not geriatric assessment in care for older patients. Physicians had varied responses about use of frontline brentuximab vedotin (Bv)-based therapy based on perceptions about benefit versus toxicity. Our work suggests a need to further understand the heterogeneity of clinical practices, especially in the post-approval setting of new therapies.

Abstract
The use of functional quantitative biomarkers extracted from routine PET-CT scans to characterize clinical responses in patients with lymphoma is gaining increased attention, and these biomarkers can outperform established clinical risk factors. Total metabolic tumour volume enables individualized estimation of survival outcomes in patients with lymphoma and has shown the potential to predict response to therapy suitable for risk-adapted treatment approaches in clinical trials. The deployment of machine learning tools in molecular imaging research can assist in recognizing complex patterns and, with image classification, in tumour identification and segmentation of data from PET-CT scans. Initial studies using fully automated approaches to calculate metabolic tumour volume and other PET-based biomarkers have demonstrated appropriate correlation with calculations from experts, warranting further testing in large-scale studies. The extraction of computer-based quantitative tumour characterization through radiomics can provide a comprehensive view of phenotypic heterogeneity that better captures the molecular and functional features of the disease. Additionally, radiomics can be integrated with genomic data to provide more accurate prognostic information. Further improvements in PET-based biomarkers are imminent, although their incorporation into clinical decision-making currently has methodological shortcomings that need to be addressed with confirmatory prospective validation in selected patient populations. In this Review, we discuss the current knowledge, challenges and opportunities in the integration of quantitative PET-based biomarkers in clinical trials and the routine management of patients with lymphoma.

Thermoresponsive Polypeptide Fused L-Asparaginase with Mitigated Immunogenicity and Enhanced Efficacy in Treating Hematologic Malignancies. ADVANCED SCIENCE (WEINHEIM, BADEN-WURTTEMBERG, GERMANY) 2023; 10:e2300469.

Abstract
L-Asparaginase (ASP) is well-known for its excellent efficacy in treating hematological malignancies. Unfortunately, the intrinsic shortcomings of ASP, namely high immunogenicity, severe toxicity, short half-life, and poor stability, restrict its clinical usage. Poly(ethylene glycol) conjugation (PEGylation) of ASP is an effective strategy to address these issues, but it is not ideal in clinical applications due to complex chemical synthesis procedures, reduced ASP activity after conjugation, and pre-existing anti-PEG antibodies in humans. Herein, the authors genetically engineered an elastin-like polypeptide (ELP)-fused ASP (ASP-ELP), a core-shell structured tetramer predicted by AlphaFold2, to overcome the limitations of ASP and PEG-ASP. Notably, the unique thermosensitivity of ASP-ELP enables the in situ formation of a sustained-release depot post-injection with zero-order release kinetics over a long time. The in vitro and in vivo studies reveal that ASP-ELP possesses increased activity retention, improved stability, extended half-life, mitigated immunogenicity, reduced toxicity, and enhanced efficacy compared to ASP and PEG-ASP. Indeed, ASP-ELP treatment in leukemia or lymphoma mouse models of cell line-derived xenograft (CDX) shows potent anti-cancer effects with significantly prolonged survival. The findings also indicate that artificial intelligence (AI)-assisted genetic engineering is instructive in designing protein-polypeptide conjugates and may pave the way to develop next-generation biologics to enhance cancer treatment.

Abstract
The treatment of Hodgkin lymphoma, using cytotoxic chemotherapy and selective radiotherapy, has resulted in progressively increasing cure rates over the last 40 years. Recent studies have been directed at using response-adapted approaches to modulate treatment according to the responses seen using functional imaging, with the aim of balancing the probability of cure against the toxicity of more extensive treatments, in particular the risks of infertility, second malignancy and cardiovascular disease. The results of these studies suggest that we have reached the limits of what might be expected from the conventional treatments, but the arrival of antibody-based therapies, specifically antibody-drug conjugates and immune checkpoint blocking antibodies, now holds out the prospect of further improvements. The next challenge will be to select those groups for whom they are most needed.

Abstract
BACKGROUND previous studies have focused on the risk of cardiovascular disease (CVD)-related death in individual cancers, adolescents or all cancers. OBJECTIVE to evaluate the risk of CVD-related death in older patients with cancer. METHODS older patients with cancer (over 65 years) of 16 cancers diagnosed between 1975 and 2018 were screened out from the Surveillance, Epidemiology and End Results program. The proportion of deaths, competing risk regression models, standardized mortality ratios (SMRs) and absolute excess risks (AERs) were used to assess the risk of CVD-related death. RESULTS this study included 1,141,675 older patients (median follow-up: 13.5 years). Of the 16 individual cancers, the risk of CVD death exceeded primary neoplasm death in older patients with cancers of the breast, endometrium, vulva, prostate gland, penis and melanoma of the skin over time (high competing risk group). Compared to the general older population, older patients with cancer had higher SMR and AER of CVD-related death (SMR: 1.58-4.23; AER: 21.16-365.89), heart disease-related death (SMR: 1.14-4.16; AER: 16.29-301.68) and cerebrovascular disease-related death (SMR: 1.11-4.66; AER: 3.02-72.43), with the SMR trend varying with CVD-related death competing risk classifications. The risk of CVD-related death in the high-competing risk group was higher than in the low-competing risk group. CONCLUSIONS for older patients with cancer, six of 16 individual cancers, including breast, endometrium, vulva, prostate gland, penis and melanoma of the skin was at high risk of CVD-related death. Management for long-term cardiovascular risk in older patients with cancer is needed.

Abstract
We conducted a Surveillance, Epidemiology, and End Results Program (SEER-18) registry analysis of classical Hodgkin lymphoma (cHL) patients more than 60 years old and compared outcomes of those diagnosed between 2006 and 2010 (cohort 1) to those identified between 2011 and 2015 (cohort 2) based on treatment era and race. Cohort 1 had a median overall survival (OS) of 4 years and cohort 2 had a median OS of 4.75 years [hazard ratio (HR): 0.92 (0.85-1.00); p = 0.052]. Non-Hispanic blacks (NHBs) had a similar 5-year OS compared to non-Hispanic whites (NHWs) of 48.6% vs. 50.2% (HR: 0.95 [0.79-1.15]; p > 0.99); on the contrary, Hispanics had worse 5-year OS of 41.8% vs. 48.6% (HR: 1.24 [1.09-1.41]; p < 0.001). NHW was the only race that had improvement in 5-year OS in 2011-2015 compared to 2006-2010 (51% vs. 46.5%, p = 0.002). In the multivariable analysis, older age, male gender, stage III-IV, unmarried status, Hispanic race, lack of chemotherapy, and diagnosis in 2006-2010 were associated with worse OS. Lymphoma was the most common cause of death in 60% of patients. In conclusion, elderly cHL patients diagnosed after 2010 had improved OS by nine months that was most prevalent in NHWs, and disparity in OS existed between NHWs and Hispanics throughout the study period.

Abstract
Objective The study aimed to evaluate the non-cancer-specific death risk and identify the risk factors affecting the non-cancer-specific survival (NCSS) in patients with primary central nervous system lymphoma (PCNSL). Methods This multi-center cohort study included 2497 patients with PCNSL in the Surveillance, Epidemiology and End Results (SEER) database from 2007 to 2016, with a mean follow-up of 4.54 years. The non-cancer-specific death risk in patients with PCNSL and primary central nervous system diffuse large B-cell lymphoma (PCNS-DLBCL) was evaluated using the proportion of deaths, standardized mortality ratio (SMR), and absolute excess risk (AER). Univariate and multivariate competing risk regression models were utilized to identify the risk factors of NCSS. Results PCNSL was the most frequent cause of death in PCNSL patients (75.03%). Non-cancer-specific causes constituted a non-negligible portion of death (20.61%). Compared with the general population, PCNSL patients had higher risks of death from cardiovascular disease (CVD) (SMR, 2.55; AER, 77.29), Alzheimer's disease (SMR, 2.71; AER, 8.79), respiratory disease (SMR, 2.12; AER, 15.63), and other non-cancer-specific diseases (SMR, 4.12; AER, 83.12). Male sex, Black race, earlier year of diagnosis (2007-2011), being unmarried, and a lack of chemotherapy were risk factors for NCSS in patients with PCNSL and PCNS-DLBCL (all P < 0.05). Conclusion Non-cancer-specific causes were important competing causes of death in PCNSL patients. More attention is recommended to non-cancer-specific causes of death in the management of PCNSL patients.

Abstract
BACKGROUND Chronic fatigue (CF), substantial fatigue for ≥ six months, can manifest as a late effect (LE) after cancer treatment, and may affect several aspects of life. In a Norwegian cohort of Hodgkin's lymphoma survivors (HLS), more than a decade after contemporary risk-adapted treatment regimens with limited use of radiotherapy (RT), we assessed: (1) Prevalence of, (2) factors associated with (3) and implications of CF on socioeconomic status (SES) and work ability (WA). MATERIAL AND METHODS HLS treated between 1997-2006, aged 8-49 years at diagnosis, were invited to participate in a population-based cross-sectional study on late effects in 2018-2019. In a mailed questionnaire, HLS responded to a fatigue questionnaire (FQ), work ability score (WAS) and short-form health survey (SF-36). Disease- and treatment data were extracted from hospital records. Factors associated with CF were identified by uni- and multivariate analysis. To study the implications of CF on SES and WA, a multinomial regression analysis was performed. RESULTS Invitations were extended to 518 HLS and 298 (58%) responded to FQ, of whom 42% had CF with mean (standard deviation [SD]) physical- and mental fatigue scores of 10.2 (4.3) and 5.5 (2.1) respectively. Median age at survey was 45 years, 47% were females. In multivariate analysis female sex (p = 0.03), lower education (p = 0.03), body mass index ≥30 kg/m2 (p = 0.04), and an increasing number of comorbidities (p = 0.01) were associated with CF. No association with disease stage, chemotherapy or RT was found. CF was associated with poorer WAS scores at survey (p < 0.001), unemployment (p = 0.03), and receiving disability pension (p = 0.003). CONCLUSION After risk-adapted treatment, CF is still a frequent LE among long-term HLS, without apparent association with disease or treatment-related parameters. CF is associated with reduced WA and SES. As no apparent risk reduction is seen with contemporary treatment, further studies should emphasize etiological factors of CF and treatment to alleviate this common LE.

Management of classical Hodgkin lymphoma: a look at up to date evidence and current treatment approaches. Exp Hematol Oncol 2022; 11:108. [PMID: 36575540 PMCID: PMC9793517 DOI: 10.1186/s40164-022-00360-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/02/2022] [Accepted: 12/16/2022] [Indexed: 12/28/2022] Open
Abstract
The treatment landscape of classical Hodgkin lymphoma (cHL) has undergone significant changes over the past 20 years. Gradual improvements have been made in the management of cHL patients, particularly in prolonging the survival rate for those in the relapsed setting. Most of these improvements came with the addition of brentuximab vedotin and PD1 blockade (nivolumab and pembrolizumab) into the current cHL treatment algorithms. On the other hand, the treatment approach to cHL has become more complex than ever before, with multiple ways to add and sequence therapies to achieve long-term remission. In this review, we will discuss the most up-to-date evidence on the management of cHL patients with the inclusion of ongoing clinical trials in cHL. We will provide a general overview of the current therapeutic landscape of cHL in light of these most recent data. We conclude with our perspective on how the approach to cHL treatment may evolve in the future.

Systematic review for deep inspiration breath hold in proton therapy for mediastinal lymphoma: A PTCOG Lymphoma Subcommittee report and recommendations. Radiother Oncol 2022; 177:21-32. [PMID: 36252635 DOI: 10.1016/j.radonc.2022.10.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/02/2022] [Revised: 09/14/2022] [Accepted: 10/03/2022] [Indexed: 11/06/2022]
Abstract
PURPOSE To systematically review all dosimetric studies investigating the impact of deep inspiration breath hold (DIBH) compared with free breathing (FB) in mediastinal lymphoma patients treated with proton therapy as compared to IMRT (intensity-modulated radiation therapy)-DIBH. MATERIALS AND METHODS We conducted a systematic review in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guideline using the PubMed database to identify studies of mediastinal lymphoma patients with dosimetric comparisons of proton-FB and/or proton-DIBH with IMRT-DIBH. Parameters included mean heart (MHD), lung (MLD), and breast (MBD) doses, among other parameters. Case reports were excluded. Absolute differences in mean doses > 1 Gy between comparators were considered to be clinically meaningful. RESULTS As of April 2021, eight studies fit these criteria (n = 8), with the following comparisons: proton-FB vs IMRT-DIBH (n = 5), proton-DIBH vs proton-FB (n = 5), and proton-DIBH vs IMRT-DIBH (n = 8). When comparing proton-FB with IMRT-DIBH in 5 studies, MHD was reduced with proton-FB in 2 studies, was similar (<1 Gy difference) in 2 studies, and increased in 1 study. On the other hand, MLD and MBD were reduced with proton-FB in 3 and 4 studies, respectively. When comparing proton-DIBH with proton-FB, MHD and MLD were reduced with proton DIBH in 4 and 3 studies, respectively, while MBD remained similar. Compared with IMRT-DIBH in 8 studies, proton-DIBH reduced the MHD in 7 studies and was similar in 1 study. Furthermore, MLD and MBD were reduced with proton-DIBH in 8 and 6 studies respectively. Integral dose was similar between proton-FB and proton-DIBH, and both were substantially lower than IMRT-DIBH. CONCLUSION Accounting for heart, lung, breast, and integral dose, proton therapy (FB or DIBH) was superior to IMRT-DIBH. Proton-DIBH can lower dose to the lungs and heart even further compared with proton-FB, depending on disease location in the mediastinum, and organ-sparing and target coverage priorities.

Abstract
Background Very few studies have been published on the causes of death of upper tract urothelial carcinoma (UTUC). We sought to explore the mortality patterns of contemporary UTUC survivors. Methods We performed a retrospective cohort study involving patients with upper urinary tract carcinoma from the National Cancer Institute’s Surveillance, Epidemiology, and End Results (SEER) database (2000 and 2015). We used standardized mortality ratios (SMRs) to compare death rates among patients with UTUC in the general population and excess absolute risks (EARs) to quantify the disease-specific death burden. Results A total of 10,179 patients with UTUC, including 7,133 who died, were included in our study. In total, 302 (17.17%) patients with the localized disease died of UTUC; however, patients who died from other causes were 4.8 times more likely to die from UTUC (n = 1,457 [82.83%]). Cardiovascular disease was the most common non-cancer cause of death (n = 393 [22.34% of all deaths]); SMR, 1.22; 95% confidence intervals [CI], 1.1–1.35; EAR, 35.96). A total of 4,046 (69.99%) patients with regional stage died within their follow-up, 1,413 (34.92%) of whom died from UTUC and 1,082 (26.74%) of whom died from non-cancer causes. UTUC was the main cause of death (SMR, 242.48; 95% CI, 230–255.47; EAR, 542.47), followed by non-tumor causes (SMR, 1.18; 95% CI, 1.11–1.25; EAR, 63.74). Most patients (94.94%) with distant stage died within 3 years of initial diagnosis. Although UTUC was the leading cause of death (n = 721 [54.29%]), these patients also had a higher risk of death from non-cancer than the general population (SMR, 2.08; 95% CI, 1.67–2.56; EAR, 288.26). Conclusions Non-UTUC deaths accounted for 82.48% of UTUC survivors among those with localized disease. Patients with regional/distant stages were most likely to die of UTUC; however, there is an increased risk of dying from non-cancer causes that cannot be ignored. These data provide the latest and most comprehensive assessment of the causes of death in patients with UTUC.

Long-Term Cardiovascular Mortality among 80,042 Older Patients with Bladder Cancer. Cancers (Basel) 2022; 14:cancers14194572. [PMID: 36230496 PMCID: PMC9559628 DOI: 10.3390/cancers14194572] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2022] [Revised: 09/14/2022] [Accepted: 09/16/2022] [Indexed: 11/16/2022] Open
Abstract
Simple Summary We conducted a large-scale population-based study with long-term follow-up to obtain a comprehensive assessment of death causes, especially cardiovascular disease death, among 80,042 older bladder cancer patients from a national cancer registry containing 44 years of data. To our knowledge, this was the first study to report the importance of CVD-related death as a competing risk among older patients with bladder cancer. CVD-related death surpassed BC as the leading cause of death 5–10 years after diagnosis among older BC patients, especially for patients with localized-stage and low-grade tumors. Furthermore, older BC patients had a higher risk of CVD-related death than the general population. Although BC management should be the primary focus of older BC patients, our results emphasized the importance of competing risks, the most prominent being CVD. Individual follow-up and management should focus not only on primary cancer but also on CVD-related death to minimize the risk of death in older patients with bladder cancer. Abstract Background: To identify the risk of death from cardiovascular disease (CVD) in older patients with bladder cancer (BC). Methods: This population-based study included 80,042 older BC patients (≥65 years) diagnosed between 1975 and 2018, with a mean follow-up of 17.2 years. The proportion of deaths, competing risk models, standardized mortality ratio (SMR), and absolute excess risk (AER) per 10,000 person-years were applied to identify the risk of CVD-related deaths among older BC patients. Results: For older patients with BC, CVD-related death was the chief cause of death, and cumulative CVD-related mortality also exceeded primary BC as the leading cause of death mostly 5–10 years after BC diagnosis, especially in localized-stage and low-grade subgroups. The risk of short- and long-term CVD-related death in older BC patients was higher than in the general older adult population (SMR = 1.30, 95% CI 1.28–1.32; AER = 105.68). The risk of sex-specific CVD-related deaths also increased compared to the general population of older adults, including heart disease, cerebrovascular diseases, hypertension without heart disease, atherosclerosis, aortic aneurysm and dissection, and other diseases of the arteries, arterioles, and capillaries. Conclusions: CVD-related death is an important competing risk among older BC patients and has surpassed primary BC as the chief cause of death, mainly 5–10 years after BC diagnosis. The risk of CVD-related death in older patients with BC was greater than in the general population. The management of older patients with BC should focus not only on the primary cancer but also on CVD-related death.

Abstract
BACKGROUND Five-year follow-up in a trial involving patients with previously untreated stage III or IV classic Hodgkin's lymphoma showed long-term progression-free survival benefits with first-line therapy with brentuximab vedotin, a CD30-directed antibody-drug conjugate, plus doxorubicin, vinblastine, and dacarbazine (A+AVD), as compared with doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD). A planned interim analysis indicated a potential benefit with regard to overall survival; data from a median of 6 years of follow-up are now available. METHODS We randomly assigned patients in a 1:1 ratio to receive up to six cycles of A+AVD or ABVD. The primary end point, modified progression-free survival, has been reported previously. The key secondary end point was overall survival in the intention-to-treat population. Safety was also assessed. RESULTS A total of 664 patients were assigned to receive A+AVD and 670 to receive ABVD. At a median follow-up of 73.0 months, 39 patients in the A+AVD group and 64 in the ABVD group had died (hazard ratio, 0.59; 95% confidence interval [CI], 0.40 to 0.88; P = 0.009). The 6-year overall survival estimates were 93.9% (95% CI, 91.6 to 95.5) in the A+AVD group and 89.4% (95% CI, 86.6 to 91.7) in the ABVD group. Progression-free survival was longer with A+AVD than with ABVD (hazard ratio for disease progression or death, 0.68; 95% CI, 0.53 to 0.86). Fewer patients in the A+AVD group than in the ABVD group received subsequent therapy, including transplantation, and fewer second cancers were reported with A+AVD (in 23 vs. 32 patients). Primary prophylaxis with granulocyte colony-stimulating factor was recommended after an increased incidence of febrile neutropenia was observed with A+AVD. More patients had peripheral neuropathy with A+AVD than with ABVD, but most patients in the two groups had resolution or amelioration of the event by the last follow-up. CONCLUSIONS Patients who received A+AVD for the treatment of stage III or IV Hodgkin's lymphoma had a survival advantage over those who received ABVD.

Abstract
Classical Hodgkin lymphoma (cHL) is the most common type of HL that occurs mainly in people aged between 15–30 and over 55 years. Although its general prognosis is favorable, 10%–30% of patients with cHL will ultimately develop relapsed or refractory disease (r/r cHL). Improving the cure rate of r/r cHL has proven to be challenging. Some novel agents, such as brentuximab vedotin and immune checkpoint inhibitors, which have been used in conventional regimens for patients with r/r cHL in the past decade, have been shown to have good curative effects. This paper reviews the conventional regimens for patients with r/r cHL and focuses on the newest clinical trials and treatment measures to prolong prognosis and reduce adverse events. The evaluation of prognosis plays a vital role in analyzing the risk of relapse or disease progression; thus, finding new predictive strategies may help treat patients with r/r cHL more efficaciously.

Abstract
Classical Hodgkin lymphoma (cHL) is curable in 90% of cases, but advanced stage patients who do not respond well to first‐line (1L) therapy have poorer outcomes. This retrospective study examines patient characteristics, treatment patterns, clinical outcomes, and safety management of 1L cHL therapies in common clinical practice in Italy (IT), Israel (IL), and Spain (SP). The overall sample (n = 256) included patients with stage IIb to IV cHL, of which 86.3% received ABVD as 1L therapy (n = 221). Clinical outcomes were similar for the overall population and ABVD subsample: complete response (CR) in 75% and 76.5%; 30‐month (30‐mo) survival (OS) of 92.5% and 93.6%; and 30‐mo progression‐free survival (PFS) of 70.7% and 72.6%. Thirty‐month PFS was significantly lower for patients ≥ 60 years and/or with high (4–7) IPS. Treatment‐induced pulmonary and cardiac toxicities, and febrile neutropenia occurred, respectively, in 10%, 2.3%, and 6.8% of ABVD‐treated patients. Interim PET or PET‐CT scans were performed after two cycles of 1L therapy (PET2) for 70.3% and 66.6% of the overall and ABVD cohorts, respectively. PET2 positive rates were nearly 30% (49/173), yet PET‐adapted strategy of dose modification only occurred in a small fraction of patients.

Abstract
PURPOSE In some patients with Hodgkin lymphoma (HL), proton beam therapy (PBT) may reduce the risk of radiation-related cardiovascular disease (CVD) and second cancers (SC) compared with photon radiation therapy (RT). Our aim was to identify patients who benefit the most from PBT in terms of predicted 30-year absolute mortality risks (AMR30) from CVD and SC, taking into account individual background, chemotherapy, radiation, and smoking-related risks. METHODS AND MATERIALS Eighty patients with supradiaphragmatic HL treated with PBT between 2015 and 2019 were replanned using optimal photon RT. To identify patients predicted to derive the greatest benefit from PBT compared with photon RT, doses and AMR30 from CVD and SC of the lung, breast, and esophagus were compared for all patients and across patient subgroups. RESULTS For patients with mediastinal disease below the origin of the left main coronary artery (n = 66; 82%), PBT reduced the mean dose to the heart, left ventricle, and heart valves by 1.0, 2.7, and 3.6 Gy, respectively. Based on U.S. mortality rates, PBT reduced CVD AMR30 by 0.2%, from 5.9% to 5.7%. The benefit was larger if the mediastinal disease overlapped longitudinally with the heart by ≥40% (n = 23; 29%). PBT reduced the mean dose to the heart, left ventricle, and heart valves by 3.2, 5.6, and 5.1 Gy, respectively, and reduced CVD AMR30 by 0.8%, from 7.0% to 6.2%. For patients with axillary disease (n = 25; 31%), PBT reduced the mean lung dose by 2.8 Gy and lung cancer AMR30 by 0.6%, from 2.7% to 2.1%. Breast and esophageal doses were also lower with PBT, but the effects on AMR30 were negligible. The effect of smoking on CVD and lung cancer AMR30 was much larger than radiation and chemotherapy and the differences between radiation modalities. CONCLUSIONS The predicted benefit of PBT is not universal and limited to certain categories of patients with lymphoma and lower mediastinal or axillary disease. Smoking cessation should be strongly encouraged in smokers who require thoracic RT.

Abstract
Positron emission tomography (PET)-adapted chemotherapy and radiotherapy approaches are currently used for the initial treatment of early-stage Hodgkin lymphoma (HL) with progression-free survival and overall survival exceeding 85% and 95%, respectively. However, despite general agreement on the prognostic value of interim PET in HL, frontline treatment approaches vary among institutions with respect to how pretreatment clinical risk factors determine treatment selection, the definition of PET negativity, which chemotherapy regimen to initiate and how many cycles to administer, and when to incorporate radiation. Furthermore, as recent trials have confirmed improved efficacy and manageable toxicity when brentuximab and checkpoint inhibitors are combined with frontline regimens such as doxorubicin, vinblastine, and dacarbazine in advanced-stage HL, these agents are now under evaluation as frontline therapy in early-stage HL. A number of issues will affect the use of these agents in early-stage HL, including the costs, early and late toxicities with these agents, patient population (favorable or unfavorable risk groups), how to incorporate them (concurrently or sequentially), and whether they can ultimately replace cytotoxic therapy with similar efficacy and fewer late effects. Future treatment paradigms for early-stage HL may change significantly once randomized studies are completed incorporating these agents into frontline therapy. Ideally, frontline use of brentuximab and checkpoint inhibitors in early-stage HL will result in improved outcomes compared with current PET-adapted approaches with decreased risks of late toxicities that continue to afflict long-term survivors of HL.

Abstract
BACKGROUND Although there are growing numbers of adolescent and young adult (AYA) Hodgkin lymphoma (HL) survivors, long-term overall survival (OS) patterns and disparities in this population are underreported. The aim of the current study was to assess the impact of race/ethnicity, socioeconomic status (SES), rurality, diagnosis age, sex, and HL stage over time on long-term survival in AYA HL survivors. METHODS The authors used the Surveillance, Epidemiology, and End Results (SEER) registry to identify survivors of HL diagnosed as AYAs (ages 15-39 years) between the years 1980 and 2009 and who were alive 5 years after diagnosis. An accelerated failure time model was used to estimate survival over time and compare survival between groups. RESULTS There were 15,899 5-year survivors of AYA HL identified, with a median follow-up of 14.4 years and range up to 33.9 years from diagnosis. Non-Hispanic black survivors had inferior survival compared with non-Hispanic white survivors [survival time ratio (STR): 0.71, P = 0.002]. Male survivors, older age at diagnosis, those diagnosed at higher stages, and those living in areas of higher SES deprivation had unfavorable long-term survival. There was no evidence of racial or sex-based survival disparities changing over time. CONCLUSIONS Racial, SES, and sex-based disparities persist well into survivorship among AYA HL survivors. IMPACT Disparities in long-term survival among AYA HL survivors show no evidence of improving over time. Studies investigating specific factors associated with survival disparities are needed to identify opportunities for intervention.

Abstract
BACKGROUND Cutaneous involvement by classic Hodgkin lymphoma (CHL) is an extraordinarily rare phenomenon in the current era. To date, no single large case series of cutaneous involvement by Hodgkin lymphoma has ever been reported in the literature. METHODS A comprehensive search for cases designated "skin" and "Hodgkin" was performed at different institutions between 1990 and 2020. Twenty-five cases were identified, and each case was independently reviewed by at least three board-certified dermatopathologists and/or hematopathologists. RESULTS All cases represented examples of systemic CHL with secondary skin dissemination. A single lesion, usually a tumor, nodule or infiltrative plaque was observed in 56% of cases and multiple lesions were present in 28% of cases. Most patients (86%-12/14) had a diagnosis of stage IV disease at first diagnosis. The interval between the clinical (first) diagnosis of HL and the development of skin lesions ranged between 6 and 108 months (average 33.75 months). Comprehensive histopathologic evaluation of these cases (at the initial diagnosis) revealed a diagnosis of classic HL not otherwise specified (NOS) in 60% of cases (15/25), nodular sclerosis type in 24% (6/25), mixed cellularity in 12% (3/25), and lymphocyte depleted in 4% (1/25). CONCLUSIONS We provide documentation of a large series of CHL with secondary skin involvement in association with CHL with additional clinical, morphologic, and immunophenotypic features.
