ABVD followed by BV consolidation in risk-stratified patients with limited-stage Hodgkin lymphoma. Blood Adv 2021; 4:2548-2555. [PMID: 32516414 DOI: 10.1182/bloodadvances.2020001871] [Citation(s) in RCA: 17] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2020] [Accepted: 04/24/2020] [Indexed: 01/12/2023] Open
Abstract
Approximately 90% of limited-stage Hodgkin lymphoma (HL) patients are projected to be cured with standard therapy, but many do not live their expected life span because of late treatment-related complications. New treatment paradigms are needed to reduce the use of radiation therapy (RT) as well as conventional chemotherapy drugs while improving upon current standard-of-care survival outcomes. In this phase 2 multicenter study, patients with non-bulky limited-stage HL received doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) followed by brentuximab vedotin (BV) consolidation. Forty-one patients were enrolled, and patient characteristics included median age of 29 years (range, 19 to 67 years), 58% were female, 45% had unfavorable disease, and 98% had stage II disease. Based on positron emission tomography (PET)-based risk stratification, patients received 2 to 6 cycles of ABVD followed by 6 cycles of BV. After ABVD followed by BV, 95% of evaluable patients (37 out of 39; 95% confidence interval [CI], 83%-99%) achieved PET-negative status. In the intent-to-treat patient population, the estimated 3-year progression-free survival (PFS) rate was 92%, and the overall survival (OS) rate was 97%, with a median follow-up of 47 months. All 37 patients who achieved negative PET status after BV consolidation effectively avoided RT and remain in remission with estimated 3-year PFS and OS rates of 100%. In conclusion, BV demonstrates encouraging clinical activity when it follows ABVD therapy in limited-stage HL. Early incorporation of BV may reduce the use of RT as well as conventional chemotherapy drugs while achieving favorable survival outcomes in risk-stratified patients with non-bulky limited-stage HL. This trial was registered at www.clinicaltrials.gov as #NCT01578967.

Pediatr Blood Cancer 2021; 68:e28835. [PMID: 33314726 DOI: 10.1002/pbc.28835] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/01/2020] [Revised: 10/18/2020] [Accepted: 11/16/2020] [Indexed: 11/09/2022]
Abstract
BACKGROUND People who receive treatment for cancer during childhood often experience subsequent complications of therapy, known as late effects, which can lead to an increased risk of death. PROCEDURE Using deidentified population-based data from the Australian Childhood Cancer Registry for children aged 0-14 diagnosed with cancer during the period 1983-2011 and who survived for a minimum of 5 years, we examined disease-related deaths (other than cancer recurrence or second primary cancers) that occurred up to 31 December 2016. Risk of death relative to the general population was approximated using standardised mortality ratios (SMRs). Treatment received was stratified according to the intensity of treatment rating, version 3 (ITR-3). RESULTS During the study period, 82 noncancer disease-related deaths were recorded among 13 432 childhood cancer survivors, four times higher than expected (SMR = 4.43, 95% CI = 3.57-5.50). A clear link to treatment intensity was observed, with the relative risk of noncancer disease-related mortality being twice as high for children who underwent 'most intensive' treatment (SMR = 5.94, 95% CI = 3.69-9.55) compared to the 'least intensive' treatment group (SMR = 2.98, 95% CI = 1.42-6.24; Ptrend = .01). Thirty-year cumulative mortality from noncancer disease-related deaths was estimated at 1.4% (95% CI = 1.1-1.9) after adjusting for competing causes of death such as cancer, accidents, or injuries. CONCLUSIONS Although childhood cancer survivors are at increased relative risk of death from noncancer diseases, particularly those who undergo more intensive treatment, the cumulative mortality within 30 years of diagnosis remains small. Knowledge of late effects can guide surveillance of survivors and treatment modification, without wanting to compromise the high rates of survival.

Abstract
Second breast cancer (SBC) is the most common solid cancer among Hodgkin Lymphoma (HL) female survivors. We reviewed the related modifying risk factors, radiation-induced carcinogenesis, tumors characteristics, management specificities, prevention and surveillance modalities based on current evidence. The risk of developing SBC may be influenced essentially by the age at HL treatment, follow-up latency, dose of irradiation received and the extent of irradiated field. SBCs generally develop at younger age, they are often bilateral, and exhibit more aggressive biological features and worse prognosis. No firm answer about the benefits of breast surveillance is provided by literature, but compelling evidence tends toward a clinical benefit in early detection. Increasing awareness among health providers' care and current survivors as well as the implementation of screening measures is crucial. Great efforts are ongoing in individualizing treatment strategies for future HL patients and response-adapted approaches are holding promise in prevention of these second malignancies.

Abstract
Introduction Advances in treatments for Hodgkin Lymphoma (HL) have significantly increased survival of childhood and adult patients; however, the leading cause of death in HL survivors is due to secondary malignancy following HL treatment [1,2]. Among women treated for HL, breast cancer (BC) is the most common secondary malignancy [3]. We explored if an association exists between HL and BC exists within families. Methods Utilizing the Utah Population Database and the Utah Cancer Registry, we identified 988 women with HL, and no history of BC prior to HL, diagnosed in Utah from 1966-2014. We examined if women with HL were at greater risk of developing BC based on the presence or absence of family history of BC. We also examined the familial recurrence risk of BC among female FDRs of women with HL and BC using Cox regression methods. Result Among 988 female HL patients, 42 (4.3%) were diagnosed with subsequent BC while among 9,876 matched controls, 280 controls (2.8%) were diagnosed with BC from 1966-2014 (P < 0.05). We observed a significant 3-fold increased risk of BC in the first-degree relatives (parent, full sibling, or child of patient) of female HL patients with subsequent BC, compared to FDR in controls (HR = 2.8, 95%CI 1.4-5.6; P = 0.005). Female HL patients who had a family history of BC were significantly more likely to develop BC, compared to HL patients with no history of BC among relatives (HR = 3.3, 95%CI 1.6-7.1; P = 0.002). Conclusion Women with HL and a family history of BC are at even higher than anticipated risk of BC, as are their female relatives. Obtaining a thorough family history for a woman preparing to undergo therapy for HL is important for treatment decisions for HL and maintaining an up to date family history over time is also important for the management of a woman's ongoing cancer risks and her surveillance strategy following survival of HL.

Abstract
Background Although patients with Hodgkin's lymphoma (HL) achieve prolonged survival, long-term complications are a major cause of morbidity and mortality among long-term survivors of HL. Methods We retrospectively evaluated long-term complications in 336 HL survivors treated between January 1990 and January 2006 at the Department of Medical Oncology of the Hacettepe University Institute of Oncology who were >16 years old at presentation. All patients were regularly followed up every 3 months for the first 2 years after complete response, biannually for 3 years, and annually after 5 years. Results Median follow-up was 8.5 years. The mean age (±SD) of the patients at the time of diagnosis was 35.7 ± 13.1 years. The male to female ratio was 61%/39%. During follow-up, 29 second malignancies (8.6%) were diagnosed in 28 patients with HL; 22 were solid tumors and 7 were hematological malignancies. Forty-seven (14.0%) of all patients with HL were found to have thyroid abnormalities. During follow-up, 54 (16.1%) patients developed cardiovascular complications. Overall, 29 (8.6%) patients developed late pulmonary toxicities. The cumulative number of chronic viral infections was 13 (3.9%). Conclusions Long-term survivors of HL need to be properly followed up not only for disease control but also for evaluation of possible late morbidities to minimize the consequences.

Abstract
The purpose of the study was to determine if abdomen/pelvis computed tomography (CT) can be safety omitted in the initial staging of a subgroup of children affected by Hodgkin Lymphoma (HL). Every participating center of A.I.E.O.P (Associazione Italiana di Ematologia ed Oncologia Pediatrica) sent local staging reports of 18F‐fluorodeoxyglucose positron emission tomography (PET) and abdominal ultrasound (US) along with digital images of staging abdomen/pelvis CT to the investigation center where the CT scans were evaluated by an experienced pediatric radiologist. The local radiologist who performed the US was unaware of local CT and PET reports (both carried out after US), and the reviewer radiologist examining the CT images was unaware of local US, PET and CT reports. A new abdominal staging of 123 patients performed on the basis of local US report, local PET report, and centralized CT report was then compared to a simpler staging based on local US and PET. No additional lesion was discovered by CT in patients with abdomen/pelvis negativity in both US and PET or isolated spleen positivity in US (or US and PET), and so it seems that in the initial staging, abdomen/pelvis CT can be safety omitted in about 1/2 to 2/3 of children diagnosed with HL.

Abstract
Late complications affecting Hodgkin lymphoma (HL) survivors are well described in paediatric and adult-based publications. This study determined the late morbidity and mortality risk for 442 teenage and young adult (TYAs) 5-year HL survivors, diagnosed at 15-24 years of age between 1970 and 1999, identified from the British Columbia Cancer Registry. Treatment details were abstracted from charts. Survivors and a matched comparison cohort were linked to provincial administrative health datasets until December 2006 and regression analysis was performed, providing risk ratios regarding mortality, secondary malignancy and morbidity causing hospitalisation. Sixty (13·6%) survivors experienced late mortality with excess deaths from secondary cancer [standardised mortality ratio (SMR) 18·6; 95% confidence interval (CI) 11-29·4] and non-malignant disease (SMR 3·6; 95% CI 2·2-5·5). Excess secondary cancers (standardised incidence ratio 7·8; 95% CI 5·6-10·5) were associated with radiotherapy [Hazard ratio (HR) 2·7; 95% CI 1-7·7] and female gender (HR 1·8; 95% CI 1-3·4). Of 281 survivors treated between 1981 and 1999, 143 (51%) had morbidity resulting in hospitalisation (relative risk 1·45; 95% CI 1·22-1·73). Hospitalisation significantly increased with combined modality therapy, chemotherapy alone and recent treatment era. TYA HL survivors have excess risk of mortality and secondary malignancy continuing 30 years from diagnosis. Radiotherapy is associated with secondary malignancy and current response-adapted protocols attempt to minimise exposure, but late morbidity causing hospitalisation remains significant.

Abstract
Hodgkin lymphoma in children is a highly curable malignancy with current approaches utilizing combined modality therapy and a risk-adapted approach. The combination of anthracyclines, bleomycin, and radiotherapy, as well as other alkylating agents, are significant risk factors for secondary malignancies and cardiopulmonary toxicity. Therefore, current strategies aim to optimize cure rates while minimizing late effects. The role of radiotherapy has been examined in recent pediatric trials, with varying results. However, they provide evidence, as a whole, for the omission of radiotherapy for a subgroup of patients, without compromising outcomes.

Abstract
Hodgkin's lymphoma (HL) is one of the most curable hematologic diseases with an overall response rate over 80%. However, despite this therapeutic efficacy, HL survivors show a higher morbidity and mortality than other people of the same age because of long-term therapy-related events. In the last decades, many efforts have been made to reduce these effects through the reduction of chemotherapy dose, the use of less toxic chemotherapeutic agents, and the introduction of new radiation techniques. In this paper, we will describe the main long-term effects related to chemotherapy and radiotherapy for HL, the efforts to reduce toxicity made in the last years, and the clinical aspects which have to be taken into consideration in the followup of these patients.

Abstract
Despite the claim in the published literature, the introduction of proton therapy for children is not analogous to the evolution of conformal photon irradiation relying on the understanding of the impact of altered dose distributions. The differences in radiobiological effect when comparing photons with protons mean that we are comparing a known entity with an unknown entity: the dose-volume histogram for proton therapy might mean something substantially different from the dose-volume histogram for photon therapy. The multifaceted difference between the 2 modalities supports the argument for careful evaluation, follow-up, and clinical trials with adverse event monitoring when using proton therapy in children. We review the current data on the outcome of proton therapy in a range of pediatric tumors and compare them with the often excellent results of photon therapy in the setting of multidisciplinary management of childhood cancer. It is hoped that the apparent dosimetric advantage of proton therapy over photons will lead to improved indications for therapy, disease control, and functional outcomes. Although physical dose distribution is of clear importance, the multimodality management of children by an expert pediatric oncology team and the availability of ancillary measures that improve the quality of treatment delivery may be more important than the actual beam. In addition, current estimates of the benefit of proton therapy over photon therapy based on toxicity reduction will only be realized when survivorship has been achieved. Once substantive proton therapy data become available, it will be necessary to demonstrate benefit in clinically relevant outcome measures in comparison with best existing photon outcome data. Such an effort will require improved funding and appreciation for late effects research. Only real clinical outcome data combined with better understanding of the radiobiological differences between protons and photons will help us to further reduce side effects in children and exploit the full curative potential of this relatively new modality.
