ABSTRACT
CD19-targeted chimeric antigen receptor (CAR) T-cell therapy has revolutionized treatment for patients with relapsed/refractory large B-cell lymphoma (LBCL). However, data available concerning the impact of the prognostic value of quantitative 18F-fluorodeoxyglucose positron emission tomography-computed tomography (FDG PET/CT) parameters on the CAR T-related outcomes and toxicities are limited. Therefore, we aimed to evaluate the predictive value of pre- and post-CAR T metabolic parameters on survival and toxicities following CAR T-cell therapy. Fifty-nine patients with PET/CT scans done pre-and post-CAR T infusion were retrospectively identified and analyzed in a single institution database of LBCL patients treated with commercial CD19-targeted CAR T-cell therapy. The median follow-up was 10.7 months [interquartile range (IQR): 2.6-25.5 months]. The overall response (complete response-CR and partial response) and CR rates post-CAR T were 76% (n = 45) and 53% (n = 31), respectively. On univariate analysis, low pre-CAR T total lesion glycolysis (TLG) and metabolic tumor volume (MTV) predicted improved overall response post-CAR T (OR = 4.7, p = 0.01, OR = 9.5, p = 0.03, respectively) and CR post-CAR T (OR = 12.4, p = 0.0004, OR = 10.9, p = 0.0001, respectively). High TLG pre-CAR T was correlated with cytokine release syndrome (CRS, OR = 3.25, p = 0.04). High MTV pre-CAR T was correlated with developing immune effector cell neurotoxicity syndrome (ICANS) events (OR = 4.3, p = 0.01), and high SUV pre-CAR T was associated with grade 3-4 neurological events (OR = 12, p = 0.01). High MTV/TLG/SUVmax post-CAR T were significantly associated with inferior Overall survival (OS). On multivariate analysis, high TLG pre-CAR T (HR = 2.4, p = 0.03), age ≥60 (HR = 2.7, p = 0.03), and bulky disease (≥5 cm) at the time of apheresis (HR = 2.5, p = 0.02) were identified to be independent prognostic factors for inferior PFS. High MTV post-CAR T was identified as the most prognostic factor associated with inferior OS.

Despite the success of CD19-targeted chimeric antigen receptor (CAR T)-cell therapy in patients with relapsed/refractory large B-cell lymphoma (LBCL), there is a need for effective salvage strategies post-CAR T-cell therapy failure. We conducted a multi-institutional retrospective study of patients who relapsed following CAR T-cell therapy (axicabtagene ciloleucel [axi-cel] or tisagenlecleucel [tisa-cel]) and received salvage therapies (radiation therapy [RT] alone, systemic therapy alone, or combined modality therapy [CMT]). A total of 120 patients with post-CAR T relapsed LBCL received salvage therapies (RT alone, 25 patients; CMT, 15 patients; systemic therapy alone, 80 patients). The median follow-up from CAR T-cell infusion was 10.2 months (interquartile range, 5.2-20.9 months). Failure occurred in previously involved sites prior to CAR T-cell therapy in 78% of patients (n=93). A total of 93 sites were irradiated in 54 patients who received any salvage RT post-CAR T failure. The median dose/fractionation were 30 Gy (range, 4-50.4 Gy) and 10 fractions (range, 1-28 fractions). The 1-year local control rate for the 81 assessable sites was 84%. On univariate analysis, the median overall survival (OS) from the start date of RT was significantly higher among patients who received comprehensive RT versus focal RT (19.1 months vs. 3.0 months; P=<0.001). Twenty-three of 29 patients who received comprehensive RT had limited-stage disease. Among these, there was no difference in median OS among the patients who received RT alone versus those who received RT followed by additional therapies (log-rank P=0.2). On multivariate survival analysis, achieving PR or CR post-CAR T (hazard ratio =0.5; 95% confidence interval: 0.3-0.9; P=0.01) was independently associated with superior OS. Our findings suggest that RT can provide local control for LBCL relapsed post-CAR T-cell therapy, particularly in patients with limited-stage relapsed disease treated with comprehensive RT.

In this review focused on lymphoma and the central nervous system (CNS), we summarize recent developments in the management of primary (PCNSL) and secondary CNS lymphoma (SCNSL), treatment of CNS lymphoma in the older population, the neuroradiological assessment of CNS lymphoma and finally highlight the ongoing debate on optimal CNS prophylaxis. The section on PCNSL focuses on the different approaches available for frontline treatment in Europe and the United States and discusses consolidation strategies. We then highlight available strategies to treat PCNSL in the elderly population, an area of unmet need. New therapies aiming at minimizing toxicity and prioritizing quality of life are emerging for these patients. Secondary CNS lymphoma, especially in the relapsed/refractory setting is another area of unmet need, and the efficacy of CAR-T cell therapy is being explored. We provide an overview of the imaging challenges in the neuroradiological assessment of CNS lymphoma. Finally, the section on CNS prophylaxis summarizes recent findings from large retrospective studies challenging the efficacy of present approaches to prophylaxis in higher-risk patients with lymphoma.
ABSTRACT
The International Lymphoma Radiation Oncology Group (ILROG) guidelines for using radiation therapy (RT) in hematological malignancies are widely used in many countries. The emergency situation created by the COVID-19 pandemic may result in limitations of treatment resources. Furthermore, in recognition of the need to also reduce the exposure of patients and staff to potential infection with COVID-19, the ILROG task force has made recommendations for alternative radiation treatment schemes. The emphasis is on maintaining clinical efficacy and safety by increasing the dose per fraction while reducing the number of daily treatments. The guidance is informed by adhering to acceptable radiobiological parameters and clinical tolerability. The options for delaying or omitting RT in some hematological categories are also discussed.

Nodular lymphocyte-predominant Hodgkin lymphoma (NLPHL) is an uncommon histologic variant, and the optimal treatment of stage I-II NLPHL is undefined. We conducted a multicenter retrospective study including patients ≥16 years of age with stage I-II NLPHL diagnosed from 1995 through 2018 who underwent all forms of management, including radiotherapy (RT), combined modality therapy (CMT; RT+chemotherapy [CT]), CT, observation after excision, rituximab and RT, and single-agent rituximab. End points were progression-free survival (PFS), freedom from transformation, and overall survival (OS) without statistical comparison between management groups. We identified 559 patients with median age of 39 years: 72.3% were men, and 54.9% had stage I disease. Median follow-up was 5.5 years (interquartile range, 3.1-10.1). Five-year PFS and OS in the entire cohort were 87.1% and 98.3%, respectively. Primary management was RT alone (n = 257; 46.0%), CMT (n = 184; 32.9%), CT alone (n = 47; 8.4%), observation (n = 37; 6.6%), rituximab and RT (n = 19; 3.4%), and rituximab alone (n = 15; 2.7%). The 5-year PFS rates were 91.1% after RT, 90.5% after CMT, 77.8% after CT, 73.5% after observation, 80.8% after rituximab and RT, and 38.5% after rituximab alone. In the RT cohort, but not the CMT cohort, variant immunoarchitectural pattern and number of sites >2 were associated with worse PFS (P < .05). Overall, 21 patients (3.8%) developed large-cell transformation, with a significantly higher transformation rate in those with variant immunoarchitectural pattern (P = .049) and number of involved sites >2 (P = .0006). OS for patients with stage I-II NLPHL was excellent after all treatments.

Diffuse large B-cell lymphoma (DLBCL) is the most common subtype of non-Hodgkin lymphoma. Historically, radiation therapy (RT) served as the primary treatment modality for patients with localized disease. While still an option for select patients who are not candidates for systemic therapy, RT is currently used most frequently as a consolidation treatment after chemoimmunotherapy. Consolidation RT is most commonly recommended after an abbreviated course of systemic therapy in patients who have bulky disease or multiple risk factors, or in the setting of a partial response. Consolidation RT is also appropriate in some patients with advanced DLBCL, including those presenting with bulky disease (≥7.5 cm). While many patients achieve sustained remissions after first-line therapy, up to 50% of patients with DLBCL will eventually relapse. The most common salvage options include second-line chemotherapy followed by high-dose chemotherapy and autologous stem cell transplantation (ASCT) and chimeric antigen receptor (CAR) T-cell therapy. RT can be used in both settings to optimize clinical outcomes. This includes consolidation RT in patients with localized presentations or bulky disease in the setting of ASCT and bridging RT in select patients undergoing CAR T-cell therapy. RT is also a valuable modality in any patient with symptomatic disease requiring palliation.

Radiotherapy (RT) can be curative in patients with localized follicular lymphoma (FL), with historical series showing a 10-year disease-free survival of 40 to 50%. As 18F-fluorodeoxyglucose (18F-FDG) positron emission tomography with computerized tomography (PET-CT) upstages 10 to 60% of patients compared to CT, we sought to evaluate outcomes in patients staged by PET-CT, to determine if more accurate staging leads to better patient selection and results. We conducted a multicenter retrospective study under the direction of the International Lymphoma Radiation Oncology Group (ILROG). Inclusion criteria were: RT alone for untreated stage I to II FL (grade 1-3A) with dose equivalent ≥24 Gy, staged by PET-CT, age ≥18 years, and follow-up ≥3 months. End points were freedom from progression (FFP), local control, and overall survival (OS). A total of 512 patients treated between 2000 and 2017 at 16 centers were eligible for analysis; median age was 58 years (range, 20-90); 410 patients (80.1%) had stage I disease; median RT dose was 30 Gy (24-52); and median follow-up was 52 months (3.2-174.6). Five-year FFP and OS were 68.9% and 95.7%. For stage I, FFP was 74.1% vs 49.1% for stage II (P < .0001). Eight patients relapsed in-field (1.6%). Four had marginal recurrences (0.8%) resulting in local control rate of 97.6%. On multivariable analysis, stage II (hazard ratio [HR], 2.11; 95% confidence interval [CI], 1.44-3.10) and BCL2 expression (HR, 1.62; 95% CI, 1.07-2.47) were significantly associated with less favorable FFP. Outcome after RT in PET-CT staged patients appears to be better than in earlier series, particularly in stage I disease, suggesting that the curative potential of RT for truly localized FL has been underestimated.

PURPOSE: Primary breast lymphoma (PBL) comprises < 1% of breast malignancies, leading to a paucity of data to guide management. We evaluated PBL recurrence patterns across two academic hospitals in the era of modern systemic-therapy and radiotherapy. METHODS: Patients diagnosed with PBL between October 1994 and June 2016 were identified. Demographic/clinical variables were assessed via primary chart review. Local control (LC) was estimated using the cumulative incidence function and overall survival (OS) using the Kaplan-Meier method. RESULTS: Thirty-five patients were identified. Median follow-up 5.8 years (range 0.3-17.8 years). Median age at diagnosis 66 years (range 35-86 years). Indolent versus aggressive lymphoma represented 57% (n = 20) and 43% (n = 15) of the cohort, respectively. All patients with aggressive lymphoma received systemic therapy. Thirty patients (86%) received radiotherapy (RT). Breast-only RT was used in 57% (n = 20); 23% (n = 7) received regional nodal irradiation (RNI), and 6% (n = 2) received limited-field RT. Local recurrences were observed in 3% (n = 1), contralateral breast 9% (n = 3), CNS 6% (n = 2), distant non-CNS 30% (n = 10), both local and distant 3% (n = 1). There were no regional nodal recurrences. The 6-year LC rate was 95% for indolent and 81% for aggressive subtypes. The 6-year OS rate was 87% for indolent and 70% for aggressive subtypes. CONCLUSIONS: The majority of patients in this PBL cohort received breast-only RT with no nodal relapses, suggesting that prophylactic RNI may be unnecessary. Given the prevalence of contralateral breast involvement at diagnosis and at recurrence, vigilant surveillance of bilateral breasts may be warranted. The role of CNS prophylaxis requires further investigation.

OBJECTIVE: Cancer survivors treated with abdominal/pelvic radiation therapy (ART) have increased the risks of colorectal cancer (CRC), although evidence supporting early CRC screening for these patients is lacking. We sought to determine whether there is an elevated prevalence of adenomatous colorectal polyps in young survivors prior to the age when screening would be routinely recommended. DESIGN: We conducted a prospective study of early colonoscopic screening in cancer survivors aged 35-49 who had received ART ≥10â years previously. The planned sample size was based on prior studies reporting a prevalence of adenomatous polyps of approximately 20% among the average-risk population ≥50â years of age, in contrast to ≤10% among those average-risk people aged 40-50â years, for whom screening is not routinely recommended. RESULTS: Colonoscopy was performed in 54 survivors, at a median age of 45â years (range 36-49) and after median interval from radiation treatment of 19â years (10.6-43.5). Forty-nine polyps were detected in 24 patients, with 15 patients (27.8%; 95% CI 17.6% to 40.9%) having potentially precancerous polyps. Fifty-three per cent of polyps were within or at the edge of the prior ART fields. CONCLUSIONS: Young survivors treated with ART have a polyp prevalence comparable with the average-risk population aged ≥50â years and substantially higher than previously reported for the average-risk population aged 40-50â years. These findings lend support to the early initiation of screening in these survivors. CLINICAL TRIAL REGISTRATION NUMBER: NCT00982059; results.

Esophageal symptoms are common during radiation and chemotherapy. It is unclear how often these symptoms persist after therapy. We retrospectively reviewed medical records of 320 adults treated for nonmetastatic breast cancer (84), lung cancer (109), or Hodgkin and non-Hodgkin lymphoma (127) who were disease-free at 10-14 months after therapy. Treatment included chemotherapy with or without nonmediastinal radiation therapy (150 patients), chemotherapy plus sequential mediastinal radiation therapy (MRT) (48 patients), chemotherapy plus concurrent MRT (61 patients), or non-MRT only (61 patients). Proton pump inhibitor use was documented. All treatment groups had similar prevalence of the esophageal symptom of heartburn before therapy. Rates were higher during treatment in those who received MRT with or without chemotherapy, but declined by 10-14 months after treatment. However, low baseline rates of dysphagia (4%) and odynophagia (2%) increased significantly after combined chemotherapy and MRT to 72% for dysphagia and 62% for odynophagia (P < 0.01) during treatment and stayed significantly elevated over baseline with 27% of the patients having dysphagia and 11% having odynophagia at 10-14 months after treatment. The use of proton pump inhibitors by patients who had MRT with chemotherapy was significantly increased during and after treatment (P = 0.002). Dysphagia, odynophagia and the use of proton pump inhibitors were significantly more common both during and after treatment than before treatment in patients who received both chemotherapy and mediastinal radiation. Our data highlight the important challenge for clinicians of managing patients with lung cancer and lymphoma who have persistent esophageal problems, particularly dysphagia and odynophagia, at approximately 1 year after treatment.

Radiation has long been associated with carcinogenesis. Nevertheless, it is an important part of multimodality therapy for many malignancies. It is critical to assess the risk of secondary malignant neoplasms (SMNs) after radiation treatment. The authors reviewed the literature with a focus on radiation and associated SMNs for primary hematologic, breast, gynecologic, and pediatric tumors. Radiation appeared to increase the risk of SMN in all of these; however, this risk was found to be associated with age, hormonal influences, chemotherapy use, environmental influences, genetic predisposition, infection, and immunosuppression. The risk also appears to be altered with modern radiotherapy techniques. Practitioners of all specialties who treat cancer survivors in follow-up should be aware of this potential risk.

Long-term survivors of Hodgkin lymphoma (HL) are at an increased risk for a range of late complications, with subsequent malignant neoplasm and cardiovascular disease representing the 2 leading causes of death in these patients. Raising awareness, close follow-up, and adoption of selected early-detection and risk-reduction strategies may help to reduce the adverse impact of these late effects on patients. This chapter reviews known long-term complications of HL therapy, risk factors, and the timing of their occurrence. Where available, data on the efficacy of screening for selected late effects of HL are presented. Current evidence-based and consensus-based recommendations on follow-up of long-term HL survivors are also reviewed. As HL therapy evolves over time, late effects and implications on follow-up of patients treated in the contemporary era should be considered and opportunities for future research should be explored.

Disease bulk is an important prognostic factor in early stage Hodgkin lymphoma, but its definition is unclear in the computed tomography era. This retrospective analysis investigated the prognostic significance of bulky disease measured in transverse and coronal planes on computed tomography imaging. Early stage Hodgkin lymphoma patients (n=185) treated with chemotherapy with or without radiotherapy from 2000-2010 were included. The longest diameter of the largest lymph node mass was measured in transverse and coronal axes on pre-treatment imaging. The optimal cut off for disease bulk was maximal diameter greater than 7 cm measured in either the transverse or coronal plane. Thirty patients with maximal transverse diameter of 7 cm or under were found to have bulk in coronal axis. The 4-year overall survival was 96.5% (CI: 93.3%, 100%) and 4-year relapse-free survival was 86.8% (CI: 81.9%, 92.1%) for all patients. Relapse-free survival at four years for bulky patients was 80.5% (CI: 73%, 88.9%) compared to 94.4% (CI: 89.1%, 100%) for non-bulky; Cox HR 4.21 (CI: 1.43, 12.38) (P=0.004). In bulky patients, relapse-free survival was not impacted in patients treated with chemoradiotherapy; however, it was significantly lower in patients treated with chemotherapy alone. In an independent validation cohort of 38 patients treated with chemotherapy alone, patients with bulky disease had an inferior relapse-free survival [at 4 years, 71.1% (CI: 52.1%, 97%) vs 94.1% (CI: 83.6%, 100%), Cox HR 5.27 (CI: 0.62, 45.16); P=0.09]. Presence of bulky disease on multidimensional computed tomography imaging is a significant prognostic factor in early stage Hodgkin lymphoma. Coronal reformations may be included for routine Hodgkin lymphoma staging evaluation. In future, our definition of disease bulk may be useful in identifying patients who are most appropriate for chemotherapy alone.

OBJECTIVE: A service evaluation of the new Gen-Probe APTIMA nucleic acid amplification test was performed to determine the prevalence of Trichomonas vaginalis (TV) infection in a UK sexual health clinic and identify risk factors to inform an appropriate TV screening strategy. METHOD: Unselected patients presenting with a new clinical episode were offered TV testing with Gen Probe transcription-mediated amplification (TV TMA) in addition to routine sexually transmitted infection screening. Asymptomatic females provided a self-collected vulvovaginal specimen and asymptomatic men a first-void urine sample. Symptomatic patients were examined and a urethral swab taken from men and two posterior vaginal swabs from females; one for culture and one for TV TMA testing. Demographic and clinical data were collected on all patients positive for TV infection and 100 randomly selected TV-negative controls. RESULTS: 3503 patients underwent TV TMA testing during the evaluation period. The prevalence of TV infection was 21/1483, 1.4% (95% CI 0.9% to 2.2%) in men and 72/2020, 3.6% (95% CI 2.8% to 4.5%) in women. The rate of TV positivity was higher in Black Caribbean patients compared with Caucasian patients (men 5.4% vs 0.1%, p<0.001; women 9.0% vs 1.2%, p<0.001). TV TMA detected an additional 16 infections (38%) in symptomatic women compared with culture. CONCLUSIONS: While screening all patients with TV TMA will identify more TV infections, the UK prevalence remains low and this approach is unlikely to be cost effective. In addition to testing symptomatic patients, targeted testing of high-risk asymptomatic groups using TV TMA should be considered.

BACKGROUND: Female survivors of pediatric Hodgkin lymphoma (HL) who have received chest radiotherapy are at increased risk of breast cancer. Guidelines for early breast cancer screening among these survivors are based on little data regarding clinical outcomes. This study reports outcomes of breast cancer screening with MRI and mammography (MMG) after childhood HL. METHODS: We evaluated the results of breast MRI and MMG screening among 96 female survivors of childhood HL treated with chest radiotherapy. Outcomes measured included imaging sensitivity and specificity, breast cancer characteristics, and incidence of additional imaging and breast biopsy. RESULTS: Median age at first screening was 30 years, and the median number of MRI screening rounds was 3. Ten breast cancers were detected in 9 women at a median age of 39 years (range, 24-43 years). Half were invasive and half were preinvasive. The median size of invasive tumors was 8 mm (range, 3-15 mm), and none had lymph node involvement. Sensitivity and specificity of the screening modalities were as follows: for MRI alone, 80% and 93.5%, respectively; MMG alone, 70% and 95%, respectively; both modalities combined, 100% and 88.6%, respectively. All invasive tumors were detected by MRI. Additional investigations were required in 52 patients, (54%), and 26 patients (27%) required breast biopsy, with 10 patients requiring more than 1 biopsy. CONCLUSIONS: Screening including breast MRI with MMG has high sensitivity and specificity in pediatric HL survivors, with breast cancers detected at an early stage, although it is associated with a substantial rate of additional investigations.

Pediatric Hodgkin lymphoma is a highly curable malignancy and potential long-term effects of therapy need to be considered in optimizing clinical care. An expert panel was convened to reach consensus on the most appropriate approach to evaluation and treatment of pediatric Hodgkin lymphoma. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed every 2 years by a multidisciplinary expert panel. The guideline development and review include an extensive analysis of current medical literature from peer reviewed journals and the application of a well-established consensus methodology (modified Delphi) to rate the appropriateness of imaging and treatment procedures by the panel. In those instances where evidence is lacking or not definitive, expert opinion may be used to recommend imaging or treatment. Four clinical variants were developed to assess common clinical scenarios and render recommendations for evaluation and treatment approaches to pediatric Hodgkin lymphoma. We provide a summary of the literature as well as numerical ratings with commentary. By combining available data in published literature and expert medical opinion, we present a consensus to the approach for management of pediatric Hodgkin lymphoma.

OBJECTIVE: The present study examined the factor structure of the Race-Based Traumatic Stress Symptom Scale (RBTSSS) in a sample of Asian American adults. METHOD: The sample (n = 403) comprised 78% women, ages 18-72 years, who were administered the RBTSSS in a survey. A first-order and second-order confirmatory factor analysis (CFA) were conducted. RESULTS: The RBTSSS demonstrated good internal consistency in the present study, Cronbach's αs = .78-.94. The first-order CFA revealed mixed model fit indices, χ²(1,253) = 3,431.52, p < .001, root mean square error of approximation (RMSEA) = .066, comparative fit index (CFI) = .875, Tucker-Lewis index (TLI) = .868. The second-order CFA revealed similar mixed findings, χ²(1,267) = 3,559.93, p < .001, RMSEA = .067, CFI = .869, TLI = .863. CONCLUSIONS: Findings demonstrated mixed support for the factor structure of the RBTSSS in a sample of Asian American adults. Future research may consider additional testing of the RBTSSS in Asian Americans and further exploring the construct of racial trauma in Asian Americans.

PURPOSE: Nodular lymphocyte-predominant Hodgkin lymphoma (NLPHL) is a rare cancer, and large international cooperative efforts are needed to evaluate the significance of clinical risk factors and immunoarchitectural patterns (IAPs) for all stages of pediatric and adult patients with NLPHL. METHODS: Thirty-eight institutions participated in the Global nLPHL One Working Group retrospective study of NLPHL cases from 1992 to 2021. We measured progression-free survival (PFS), overall survival (OS), transformation rate, and lymphoma-specific death rate. We performed uni- and multivariable (MVA) Cox regression stratified by management to select factors for the lymphocyte-predominant international prognostic score (LP-IPS) validated by five-fold cross-validation. RESULTS: We identified 2,243 patients with a median age of 37 years (IQR, 23-51). The median follow-up was 6.3 years (IQR, 3.4-10.8). Most had stage I to II (72.9%) and few B symptoms (9.9%) or splenic involvement (5.4%). IAP was scored for 916 (40.8%). Frontline management included chemotherapy alone (32.4%), combined modality therapy (30.5%), radiotherapy alone (24.0%), observation after excision (4.6%), rituximab alone (4.0%), active surveillance (3.4%), and rituximab and radiotherapy (1.1%). The PFS, OS, transformation, and lymphoma-specific death rates at 10 years were 70.8%, 91.6%, 4.8%, and 3.3%, respectively. On MVA, IAPs were not associated with PFS or OS, but IAP E had higher risk of transformation (hazard ratio [HR], 1.81; P < .05). We developed the LP-IPS with 1 point each for age ≥45 years, stage III-IV, hemoglobin <10.5 g/dL, and splenic involvement. Increasing LP-IPS was significantly associated with worse PFS (HR, 1.52) and OS (HR, 2.31) and increased risk of lymphoma-specific death (HR, 2.63) and transformation (HR, 1.41). CONCLUSION: In this comprehensive study of all ages of patients with NLPHL, we develop the LP-IPS to identify high-risk patients and inform upcoming prospective clinical trials evaluating de-escalation of therapy for patients with low LP-IPS scores (<2).
