Second Cancers in Classical Hodgkin Lymphoma and Diffuse Large B-Cell Lymphoma: A Systematic Review by the Fondazione Italiana Linfomi. Cancers (Basel) 2022; 14:cancers14030519. [PMID: 35158787 PMCID: PMC8833346 DOI: 10.3390/cancers14030519] [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: 11/30/2021] [Revised: 01/14/2022] [Accepted: 01/18/2022] [Indexed: 11/16/2022] Open
Abstract
BACKGROUND The increase of lymphoma patient survival led to a modification of the incidence of long-term sequelae, including second malignancies (SM). Several groups have dealt with the incidence of SM, according to the primary treatment; however, a standardized approach for the early detection and screening of SM in the population of lymphoma survivors should be implemented. METHODS A systematic review was conducted by Fondazione Italiana Linfomi (FIL), in order to define the incidence of SM, the impact of modern radiotherapy on SM risk, and the usefulness of tailored follow-up and screening strategies for early diagnosis of SM. Classical Hodgkin lymphoma (cHL) and diffuse large B-cell lymphoma (DLBCL) survivors were investigated. The MEDLINE, Embase, and Cochrane Library databases were checked for relevant reports published up to January 2020. The selection process was reported according to the preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines. RESULTS A total of 27 full-text manuscripts resulted as eligible for the analysis. The incidence of SM in cHL patients treated with ABVD was higher compared to the general population and was even higher in patients treated with intensified regimens. The risk increased over time, as well as after 10-15 years from therapy, and was augmented by radiotherapy exposure. In DLBCL, more intensive regimens (i.e., R-CHOEP or R-MegaCHOEP) vs. R-CHOP were associated with a higher SM incidence. Salvage chemotherapy and autologous stem cell transplants increased the risk of SM in both cHL and DLBCL cohorts. A lower incidence of SM, particularly of breast cancer (BC), was shown in cohorts of cHL survivors treated with reduced radiation volumes and doses (involved fields vs. extended fields), but robust trials are still lacking. Considering the advantage of a structured screening for early detection of SM, all the included studies regarded cHL survivors and screening strategy for early BC detection. Moreover, the authors discuss additional papers, to guide the early diagnosis of lung, colorectal, skin, and thyroid cancer in patients at risk due to family history, drug or RT exposure, or unhealthy lifestyles. These screening strategies all passed through patient awareness. CONCLUSION A modern approach to chemotherapy and radiotherapy led to a lower risk of SM, which should be confirmed over time. Early detection of secondary cancers could be achieved through a tailored screening program, according to the individual risk profile.

DEUTSCHES ARZTEBLATT INTERNATIONAL 2021; 118:205-211.

Abstract
BACKGROUND Approximately half of all patients with tumors need radiotherapy. Long-term survivors may suffer from late sequelae of the treatment. The existing radiotherapeutic techniques are being refined so that radiation can be applied more precisely, with the goal of limiting the radiation exposure of normal tissue and reducing late sequelae. METHODS This review is based on the findings of a selective search in PubMed for publications on late sequelae of conventional percutaneous radiotherapy, January 2000 to May 2020. Late sequelae affecting the central nervous system, lungs, and heart and the development of second tumors are presented, and radiobiological mechanisms and the relevant technical and conceptual considerations are discussed. RESULTS The current standard of treatment involves the use of linear accelerators, intensity-modulated radiotherapy (IMRT), image-guided and respiratory-gated radiotherapy, and the integration of positron emission tomography combined with computed tomography (PET-CT) in radiation treatment planning. Cardiotoxicity has been reduced with regard to the risk of coronary heart disease after radiotherapy for Hodgkin's lymphoma (hazard ratio [HR] 0.44 [0.23; 0.85]). It was also found that the rate of radiation- induced pneumonitis dropped from 7.9% with conformal treatment to 3.5% with IMRT in a phase III lung cancer trial. It is hoped that neurocognitive functional impairment will be reduced by hippocampal avoidance in modern treatment planning: an initial phase III trial yielded a hazard ratio of 0.74 [0.58; 0.94]. It is estimated that 8% of second solid tumors in adults are induced by radiotherapy (3 additional tumors per 1000 patients at 10 years). CONCLUSION Special challenges for research in this field arise from the long latency of radiation sequelae and the need for largescale, well-documented patient collectives in order to discern dose-effect relationships, and take account of cofactors, when the overall number of events is small. It is hoped that further technical and conceptual advances will be made in the areas of adaptive radiotherapy, proton and heavy-ion therapy, and personalized therapy.

Abstract
The backbone of treatment for patients with advanced-stage Hodgkin lymphoma is systemic therapy. The use of radiation therapy as a component of combined-modality treatment in this setting is controversial. In this review, we describe the data in support of and against the use of radiation therapy for stage III and IV Hodgkin lymphoma. Specifically, we review the data for the use of radiation therapy in the consolidation and partial-response settings, including for patients with initial bulky disease. We also discuss the use of radiation therapy in the era of more modern systemic therapies, including checkpoint inhibitors and brentuximab vedotin.

Abstract
BACKGROUND Hodgkin lymphoma (HL) is one of the most common haematological malignancies in young adults and, with cure rates of 90%, has become curable for the majority of individuals. Positron emission tomography (PET) is an imaging tool used to monitor a tumour's metabolic activity, stage and progression. Interim PET during chemotherapy has been posited as a prognostic factor in individuals with HL to distinguish between those with a poor prognosis and those with a better prognosis. This distinction is important to inform decision-making on the clinical pathway of individuals with HL. OBJECTIVES To determine whether in previously untreated adults with HL receiving first-line therapy, interim PET scan results can distinguish between those with a poor prognosis and those with a better prognosis, and thereby predict survival outcomes in each group. SEARCH METHODS We searched MEDLINE, Embase, CENTRAL and conference proceedings up until April 2019. We also searched one trial registry (ClinicalTrials.gov). SELECTION CRITERIA We included retrospective and prospective studies evaluating interim PET scans in a minimum of 10 individuals with HL (all stages) undergoing first-line therapy. Interim PET was defined as conducted during therapy (after one, two, three or four treatment cycles). The minimum follow-up period was at least 12 months. We excluded studies if the trial design allowed treatment modification based on the interim PET scan results. DATA COLLECTION AND ANALYSIS We developed a data extraction form according to the Checklist for Critical Appraisal and Data Extraction for Systematic Reviews of Prediction Modelling Studies (CHARMS). Two teams of two review authors independently screened the studies, extracted data on overall survival (OS), progression-free survival (PFS) and PET-associated adverse events (AEs), assessed risk of bias (per outcome) according to the Quality in Prognosis Studies (QUIPS) tool, and assessed the certainty of the evidence (GRADE). We contacted investigators to obtain missing information and data. MAIN RESULTS Our literature search yielded 11,277 results. In total, we included 23 studies (99 references) with 7335 newly-diagnosed individuals with classic HL (all stages). Participants in 16 studies underwent (interim) PET combined with computed tomography (PET-CT), compared to PET only in the remaining seven studies. The standard chemotherapy regimen included ABVD (16) studies, compared to BEACOPP or other regimens (seven studies). Most studies (N = 21) conducted interim PET scans after two cycles (PET2) of chemotherapy, although PET1, PET3 and PET4 were also reported in some studies. In the meta-analyses, we used PET2 data if available as we wanted to ensure homogeneity between studies. In most studies interim PET scan results were evaluated according to the Deauville 5-point scale (N = 12). Eight studies were not included in meta-analyses due to missing information and/or data; results were reported narratively. For the remaining studies, we pooled the unadjusted hazard ratio (HR). The timing of the outcome measurement was after two or three years (the median follow-up time ranged from 22 to 65 months) in the pooled studies. Eight studies explored the independent prognostic ability of interim PET by adjusting for other established prognostic factors (e.g. disease stage, B symptoms). We did not pool the results because the multivariable analyses adjusted for a different set of factors in each study. Overall survival Twelve (out of 23) studies reported OS. Six of these were assessed as low risk of bias in all of the first four domains of QUIPS (study participation, study attrition, prognostic factor measurement and outcome measurement). The other six studies were assessed as unclear, moderate or high risk of bias in at least one of these four domains. Four studies were assessed as low risk, and eight studies as high risk of bias for the domain other prognostic factors (covariates). Nine studies were assessed as low risk, and three studies as high risk of bias for the domain 'statistical analysis and reporting'. We pooled nine studies with 1802 participants. Participants with HL who have a negative interim PET scan result probably have a large advantage in OS compared to those with a positive interim PET scan result (unadjusted HR 5.09, 95% confidence interval (CI) 2.64 to 9.81, I² = 44%, moderate-certainty evidence). In absolute values, this means that 900 out of 1000 participants with a negative interim PET scan result will probably survive longer than three years compared to 585 (95% CI 356 to 757) out of 1000 participants with a positive result. Adjusted results from two studies also indicate an independent prognostic value of interim PET scan results (moderate-certainty evidence). Progression-free survival Twenty-one studies reported PFS. Eleven out of 21 were assessed as low risk of bias in the first four domains. The remaining were assessed as unclear, moderate or high risk of bias in at least one of the four domains. Eleven studies were assessed as low risk, and ten studies as high risk of bias for the domain other prognostic factors (covariates). Eight studies were assessed as high risk, thirteen as low risk of bias for statistical analysis and reporting. We pooled 14 studies with 2079 participants. Participants who have a negative interim PET scan result may have an advantage in PFS compared to those with a positive interim PET scan result, but the evidence is very uncertain (unadjusted HR 4.90, 95% CI 3.47 to 6.90, I² = 45%, very low-certainty evidence). This means that 850 out of 1000 participants with a negative interim PET scan result may be progression-free longer than three years compared to 451 (95% CI 326 to 569) out of 1000 participants with a positive result. Adjusted results (not pooled) from eight studies also indicate that there may be an independent prognostic value of interim PET scan results (low-certainty evidence). PET-associated adverse events No study measured PET-associated AEs. AUTHORS' CONCLUSIONS This review provides moderate-certainty evidence that interim PET scan results predict OS, and very low-certainty evidence that interim PET scan results predict progression-free survival in treated individuals with HL. This evidence is primarily based on unadjusted data. More studies are needed to test the adjusted prognostic ability of interim PET against established prognostic factors.

Abstract
Treatment intensification to maximize disease control and reduced intensity approaches to minimize the risk of late sequelae have been evaluated in newly diagnosed Hodgkin lymphoma. The influence of these interventions on the risk of secondary malignant neoplasms, progression-free survival and overall survival is reported in the meta-analysis herein, based on individual patient data from 9498 patients treated within 16 randomized controlled trials for newly diagnosed Hodgkin lymphoma between 1984 and 2007. Secondary malignant neoplasms were meta-analyzed using Peto’s method as time-to-event outcomes. For progression-free and overall survival, hazard ratios derived from each trial using Cox regression were combined by inverse-variance weighting. Five study questions (combined-modality treatment vs. chemotherapy alone; more extended vs. involved-field radiotherapy; radiation at higher doses vs. radiation at 20 Gy; more vs. fewer cycles of the same chemotherapy protocol; standard-dose chemotherapy vs. intensified chemotherapy) were investigated. After a median follow-up of 7.4 years, dose-intensified chemotherapy resulted in better progression-free survival rates (P=0.007) as compared with standard-dose chemotherapy, but was associated with an increased risk of therapy-related acute myeloid leukemia/myelodysplastic syndromes (P=0.0028). No progression-free or overall survival differences were observed between combined-modality treatment and chemotherapy alone, but more secondary malignant neoplasms were seen after combined-modality treatment (P=0.010). For the remaining three study questions, outcomes and secondary malignancy rates did not differ significantly between treatment strategies. The results of this meta-analysis help to weigh up efficacy and secondary malignancy risk for the choice of first-line treatment for Hodgkin lymphoma patients. However, final conclusions regarding secondary solid tumors require longer follow-up.

Abstract
BACKGROUND Efficacy and the risk of severe late effects have to be well-balanced in treatment of Hodgkin lymphoma (HL). Late adverse effects include secondary malignancies which often have a poor prognosis. To synthesise evidence on the risk of secondary malignancies after current treatment approaches comprising chemotherapy and/or radiotherapy, we performed a meta-analysis based on individual patient data (IPD) from patients treated for newly diagnosed HL. OBJECTIVES We investigated several questions concerning possible changes in the risk of secondary malignancies when modifying chemotherapy or radiotherapy (omission of radiotherapy, reduction of the radiation field, reduction of the radiation dose, use of fewer chemotherapy cycles, intensification of chemotherapy). We also analysed whether these modifications affect progression-free survival (PFS) and overall survival (OS). SEARCH METHODS We searched MEDLINE and Cochrane CENTRAL trials databases comprehensively in June 2010 for all randomised trials in HL since 1984. Key international trials registries were also searched. The search was updated in March 2015 without collecting further IPD (one further eligible study found) and again in July 2017 (no further eligible studies). SELECTION CRITERIA We included randomised controlled trials (RCTs) for untreated HL patients which enrolled at least 50 patients per arm, completed recruitment by 2007 and performed a treatment comparison relevant to our objectives. DATA COLLECTION AND ANALYSIS Study groups submitted IPD, including age, sex, stage and the outcomes secondary malignant neoplasm (SMN), OS and PFS as time-to-event data. We meta-analysed these data using Petos method (SMN) and Cox regression with inverse-variance pooling (OS, PFS) for each of the five study questions, and performed subgroup and sensitivity analyses to assess the applicability and robustness of the results. MAIN RESULTS We identified 21 eligible trials and obtained IPD for 16. For four studies no data were supplied despite repeated efforts, while one study was only identified in 2015 and IPD were not sought. For each study question, between three and six trials with between 1101 and 2996 participants in total and median follow-up between 6.7 and 10.8 years were analysed. All participants were adults and mainly under 60 years. Risk of bias was assessed as low for the majority of studies and outcomes. Chemotherapy alone versus same chemotherapy plus radiotherapy. Omitting additional radiotherapy probably reduces secondary malignancy incidence (Peto odds ratio (OR) 0.43, 95% confidence interval (CI) 0.23 to 0.82, low quality of evidence), corresponding to an estimated reduction of eight-year SMN risk from 8% to 4%. This decrease was particularly true for secondary acute leukemias. However, we had insufficient evidence to determine whether OS rates differ between patients treated with chemotherapy alone versus combined-modality (hazard ratio (HR) 0.71, 95% CI 0.46 to 1.11, moderate quality of evidence). There was a slightly higher rate of PFS with combined modality, but our confidence in the results was limited by high levels of statistical heterogeneity between studies (HR 1.31, 95% CI 0.99 to 1.73, moderate quality of evidence). Chemotherapy plus involved-field radiation versus same chemotherapy plus extended-field radiation (early stages) . There is insufficient evidence to determine whether smaller radiation field reduces SMN risk (Peto OR 0.86, 95% CI 0.64 to 1.16, low quality of evidence), OS (HR 0.89, 95% C: 0.70 to 1.12, high quality of evidence) or PFS (HR 0.99, 95% CI 0.81 to 1.21, high quality of evidence). Chemotherapy plus lower-dose radiation versus same chemotherapy plus higher-dose radiation (early stages). There is insufficient evidence to determine the effect of lower-radiation dose on SMN risk (Peto OR 1.03, 95% CI 0.71 to 1.50, low quality of evidence), OS (HR 0.91, 95% CI 0.65 to 1.28, high quality of evidence) or PFS (HR 1.20, 95% CI 0.97 to 1.48, high quality of evidence). Fewer versus more courses of chemotherapy (each with or without radiotherapy; early stages). Fewer chemotherapy courses probably has little or no effect on SMN risk (Peto OR 1.10, 95% CI 0.74 to 1.62), OS (HR 0.99, 95% CI 0.73 to1.34) or PFS (HR 1.15, 95% CI 0.91 to 1.45).Outcomes had a moderate (SMN) or high (OS, PFS) quality of evidence. Dose-intensified versus ABVD-like chemotherapy (with or without radiotherapy in each case). In the mainly advanced-stage patients who were treated with intensified chemotherapy, the rate of secondary malignancies was low. There was insufficient evidence to determine the effect of chemotherapy intensification (Peto OR 1.37, CI 0.89 to 2.10, low quality of evidence). The rate of secondary acute leukemias (and for younger patients, all secondary malignancies) was probably higher than among those who had treatment with standard-dose ABVD-like protocols. In contrast, the intensified chemotherapy protocols probably improved PFS (eight-year PFS 75% versus 69% for ABVD-like treatment, HR 0.82, 95% CI 0.7 to 0.95, moderate quality of evidence). Evidence suggesting improved survival with intensified chemotherapy was not conclusive (HR: 0.85, CI 0.70 to 1.04), although escalated-dose BEACOPP appeared to lengthen survival compared to ABVD-like chemotherapy (HR 0.58, 95% CI 0.43 to 0.79, moderate quality of evidence).Generally, we could draw valid conclusions only in terms of secondary haematological malignancies, which usually occur less than 10 years after initial treatment, while follow-up within the present analysis was too short to record all solid tumours. AUTHORS' CONCLUSIONS The risk of secondary acute myeloid leukaemia and myelodysplastic syndrome (AML/MDS) is increased but efficacy is improved among patients treated with intensified chemotherapy protocols. Treatment decisions must be tailored for individual patients. Consolidating radiotherapy is associated with an increased rate of secondary malignancies; therefore it appears important to define which patients can safely be treated without radiotherapy after chemotherapy, both for early and advanced stages. For early stages, treatment optimisation methods such as use of fewer chemotherapy cycles and reduced field or reduced-dose radiotherapy did not appear to markedly affect efficacy or secondary malignancy risk. Due to the limited amount of long-term follow-up in this meta-analysis, further long-term investigations of late events are needed, particularly with respect to secondary solid tumours. Since many older studies have been included, possible improvement of radiotherapy techniques must be considered when interpreting these results.

Abstract
BACKGROUND Combined modality treatment consisting of chemotherapy followed by localised radiotherapy is the standard treatment for patients with early stage Hodgkin lymphoma (HL). However, due to long- term adverse effects such as secondary malignancies the role of radiotherapy has been questioned recently and some clinical study groups advocate chemotherapy only for this indication. OBJECTIVES To assess the effects of chemotherapy alone compared to chemotherapy plus radiotherapy in adults with early stage HL . SEARCH METHODS For the or i ginal version of this review, we searched MEDLINE, Embase and CENTRAL as well as conference proceedings (American Society of Hematology, American Society of Clinical Oncology and International Symposium of Hodgkin Lymphoma) from January 1980 to November 2010 for randomised controlled trials (RCTs) comparing chemotherapy alone versus chemotherapy regimens plus radiotherapy. For the updated review we searched MEDLINE, CENTRAL and conference proceedings to December 2016. SELECTION CRITERIA We included RCTs comparing chemotherapy alone with chemotherapy plus radiotherapy in patients with early stage HL. We excluded trials with more than 20% of patients in advanced stage. As the value of radiotherapy in addition to chemotherapy is still not clear, we also compared to more cycles of chemotherapy in the control arm. In this updated review, we also included a second comparison evaluating trials with varying numbers of cycles of chemotherapy between intervention and control arms, same chemotherapy regimen in both arms assumed. We excluded trials evaluating children only, therefore only trials involving adults are included in this updated review. DATA COLLECTION AND ANALYSIS Two review authors independently extracted data and assessed the quality of trials. We contacted study authors to obtain missing information. As effect measures we used hazard ratios (HR) for overall survival (OS) and progression-free survival (PFS) and risk ratios (RR) for response rates. Since not all trials reported PFS according to our definitions, we evaluated all similar outcomes (e.g. event-free survival) as PFS/tumour control. MAIN RESULTS Our search led to 5518 potentially relevant references. From these, we included seven RCTs in the analyses involving 2564 patients. In contrast to the first version of this review including five trials, we excluded trials randomising children. As a result, we excluded one trial from the former analyses and we identified three new trials.Five trials with 1388 patients compared the combination of chemotherapy alone and chemotherapy plus radiotherapy, with the same number of chemotherapy cycles in both arms. The addition of radiotherapy to chemotherapy has probably little or no difference on OS (HR 0.48; 95% confidence interval (CI) 0.22 to 1.06; P = 0.07, moderate- quality evidence), however two included trials had potential other high risk of bias due to a high number of patients not receiving planned radiotherapy. After excluding these trials in a sensitivity analysis, the results showed that the combination of chemotherapy and radiotherapy improved OS compared to chemotherapy alone (HR 0.31; 95% CI 0.19 to 0.52; P <0.00001, moderate- quality evidence). In contrast to chemotherapy alone the use of chemotherapy and radiotherapy improved PFS (HR 0.42; 95% CI 0.25 to 0.72; P = 0.001; moderate- quality evidence). Regarding infection- related mortality (RR 0.33; 95% CI 0.01 to 8.06; P = 0.5; low- quality evidence), second cancer- related mortality (RR 0.53; 95% CI 0.07 to 4.29; P = 0.55; low- quality evidence) and cardiac disease- related mortality (RR 2.94; 95% CI 0.31 to 27.55; P = 0.35;low- quality evidence), there is no evidence for a difference between the use of chemotherapy alone and chemotherapy plus radiotherapy. For complete response rate (CRR) (RR 1.08; 95% CI 0.93 to 1.25; P = 0.33; low- quality evidence), there is also no evidence for a difference between treatment groups.Two trials with 1176 patients compared the combination of chemotherapy alone and chemotherapy plus radiotherapy, with different numbers of chemotherapy cycles in both arms. OS is reported in one trial only, the use of chemotherapy alone (more chemotherapy cycles) may improve OS compared to chemotherapy plus radiotherapy (HR 2.12; 95% CI 1.03 to 4.37; P = 0.04; low- quality evidence). This trial also had a potential other high risk of bias due to a high number of patients not receiving planned therapy. There is no evidence for a difference between chemotherapy alone and chemotherapy plus radiotherapy regarding PFS (HR 0.42; 95% CI 0.14 to 1.24; P = 0.12; low- quality evidence). After excluding the trial with patients not receiving the planned therapy in a sensitivity analysis, the results showed that the combination of chemotherapy and radiotherapy improved PFS compared to chemotherapy alone (HR 0.24; 95% CI 0.070 to 0.88; P = 0.03, based on one trial). For infection- related mortality (RR 6.90; 95% CI 0.36 to 132.34; P = 0.2; low- quality evidence), second cancer- related mortality (RR 2.22; 95% CI 0.7 to 7.03; P = 0.18; low- quality evidence) and cardiac disease-related mortality (RR 0.99; 95% CI 0.14 to 6.90; P = 0.99; low-quality evidence), there is no evidence for a difference between the use of chemotherapy alone and chemotherapy plus radiotherapy. CRR rate was not reported. AUTHORS' CONCLUSIONS This systematic review compared the effects of chemotherapy alone and chemotherapy plus radiotherapy in adults with early stage HL .For the comparison with same numbers of chemotherapy cycles in both arms, we found moderate- quality evidence that PFS is superior in patients receiving chemotherapy plus radiotherapy than in those receiving chemotherapy alone. The addition of radiotherapy to chemotherapy has probably little or no difference on OS . The sensitivity analysis without the trials with potential other high risk of bias showed that chemotherapy plus radiotherapy improves OS compared to chemotherapy alone.For the comparison with different numbers of chemotherapy cycles between the arms there are no implications for OS and PFS possible, because of the low quality of evidence of the results.

Am J Epidemiol 2015; 182:826-33.

Abstract
The idea that epidemiologic studies should start from first exposure onward has been advocated in the past few years. The study of incident exposures is contrasted with studies of prevalent exposures in which follow-up may commence after first exposure. The former approach is seen as a hallmark of a good study and necessary for causal inference. We argue that studying incident exposures may be necessary in some situations, but it is not always necessary and is not the preferred option in many instances. Conducting a study involves decisions as to which person-time experience should be included. Although studies of prevalent exposures involve left truncation (missingness on the left), studies of incident exposures may involve right censoring (missingness on the right) and therefore may not be able to assess the long-term effects of exposure. These considerations have consequences for studies of dynamic (open) populations that involve a mixture of prevalent and incident exposures. We argue that studies with prevalent exposures will remain a necessity for epidemiology. The purpose of this paper is to restore the balance between the emphasis on first exposure cohorts and the richness of epidemiologic information obtained when studying prevalent exposures.

Abstract
Radiation therapy has a key role in the combined modality treatment of early-stage Hodgkin’s Lymphoma (HL). Nevertheless, late toxicity still remains an issue. A modern approach in HL radiotherapy includes lower doses and smaller fields, together with the implementation of sophisticated and dedicated delivery techniques. Aim of the present review is to discuss the current role of radiotherapy and its potential future developments, with a focus on major clinical trials, technological advances and their repercussion in the clinical management of HL patients.

Abstract
PURPOSE To assess therapy-related acute myeloid leukemia/myelodysplastic syndrome (t-AML/MDS) risk in patients treated for Hodgkin lymphoma (HL) on successive generations of Stanford clinical trials. PATIENTS AND METHODS Patients with HL treated at Stanford with at least 5 years of follow-up after completing therapy were identified from our database. Records were reviewed for outcome and development of t-AML/MDS. RESULTS Seven hundred fifty-four patients treated from 1974 to 2003 were identified. Therapy varied across studies. Radiotherapy evolved from extended fields (S and C studies) to involved fields (G studies). Primary chemotherapy was mechlorethamine, vincristine, procarbazine, and prednisone (MOPP) or procarbazine, mechlorethamine, and vinblastine (PAVe) in S studies; MOPP, PAVe, vinblastine, bleomycin, and methotrexate (VBM), or doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) in C studies; and VbM (reduced dose of bleomycin compared with VBM) or mechlorethamine, doxorubicin, vinblastine, vincristine, bleomycin, etoposide, and prednisone (Stanford V) in G studies. Cumulative exposure to alkylating agent (AA) was notably lower in the G studies compared with the S and C studies, with a 75% to 83% lower dose of nitrogen mustard in addition to omission of procarbazine and melphalan. Twenty-four (3.2%) of 754 patients developed t-AML/MDS, 15 after primary chemotherapy and nine after salvage chemotherapy for relapsed HL. The incidence of t-AML/MDS was significantly lower in the G studies (0.3%) compared with the S (5.7%) or C (5.2%) studies (P < .001). Additionally, in the G studies, no t-AML/MDS was noted after primary therapy, and the only patient who developed t-AML/MDS did so after second-line therapy. CONCLUSION Our data demonstrate the relationship between the cumulative AA dose and t-AML/MDS. Limiting the dose of AA and decreased need for secondary treatments have significantly reduced the incidence of t-AML/MDS, which was extremely rare in the G studies (Stanford V era).

Abstract
The purpose of this study is to apply noncoplanar intensity-modulated radiation therapy (Nonco_IMRT) to young female patients with mediastinal lymphoma. Nonco_IMRT was evaluated through a planning comparison study with coplanar IMRT (Co_IMRT) and conventional anteroposterior and posteroanterior fields (AP-PA) plans. Co_IMRT was performed with five equally spaced beams starting from a gantry angle of 216°. Nonco_IMRT used two noncoplanar beams in the sagittal plane to replace the Co_IMRT beams that directly irradiated the breasts. Nineteen young female patients were enrolled in the retrospective study. Dose coverage of the planning target volume (PTV) and the dose delivered to organs at risk (OARs) were analyzed. For all patients, PTV coverage and heart V30 were similar between the two IMRT techniques (p > 0.05). Compared to Co_IMRT, the mean dose delivered and regions receiving a low radiation dose were significantly reduced for bilateral breasts and lungs in Nonco_IMRT (p < 0.05). Breast V5 and lung V5 were relatively reduced by 21% and 12%, respectively. Compared with the conventional AP-PA plan, Nonco_IMRT had better PTV coverage and OARs sparing, except for being larger in V5 to breast and lung. In IMRT for young female patients with mediastinal lymphoma, using of Nonco_IMRT significantly reduces the radiation dose to the breasts and lungs compared with Co_IMRT, and consequently reduces the risk of breast second cancer and pulmonary toxicity. Besides young female patients, Nonco_IMRT can also benefit other mediastinal lymphoma patients.

Abstract
Management of Hodgkin's lymphoma continues to develop. Outcomes for patients with favourable-risk, early-stage disease are excellent, and serial reductions in intensity of treatment have been made to retain the excellent prognosis while reducing the late effects of treatment. Prognosis is also very good in advanced-stage disease but the rate of relapse is higher than in early-stage disease, and the optimum first-line treatment is unclear. Workers are investigating the role of functional imaging to assess whether treatment can be tailored according to response, with the most intensive therapies reserved for patients predicted to have poor outcomes. In this Seminar we critically appraise the management of Hodgkin's lymphoma in early-stage disease, advanced-stage disease, and at relapse, with a focus on late effects of treatment.

Abstract
BACKGROUND Patients successfully treated for Hodgkin's lymphoma (HL) are at known risk for subsequent malignancies, the most common of which is lung cancer. To date, no population-based study has analyzed prognostic variables for overall survival (OS) among HL survivors who developed non-small cell lung cancer (NSCLC). METHODS For 187 HL patients who developed NSCLC (among 22,648 HL survivors), we examined the impact of the following variables on OS after NSCLC diagnosis: gender, race, sociodemographic status (based upon county of residence), calendar year and age at NSCLC diagnosis, NSCLC histology and grade, HL stage and subtype, radiation for HL and latency between HL and NSCLC. Patients were grouped by NSCLC stage as follows: localized, regional or distant. All patients were reported to the population-based Surveillance, Epidemiology, and End Results program. For those variables significant on univariate analyses, hazard ratios (HR) were derived from Cox proportional hazards model. RESULTS Sociodemogaphic status, gender and latency between NSCLC and HL did not significantly affect OS of any NSCLC stage group. For patients with localized NSCLC, a history of mixed celluarlity HL was associated with a 3-fold improved OS (P=0.006). For patients with regional NSCLC, prior radiotherapy for HL was associated with a 2-fold worse OS (P=0.025). CONCLUSIONS A history of mixed cellularity HL subtype and a history of no radiotherapy for HL are favorable prognostic factors among patients who develop NSCLC. Further research into clinicopathologic and treatment-associated variables potentially affecting OS after second primary NSCLC among HL survivors is warranted.

Abstract
BACKGROUND Combined modality treatment (CMT) consisting of chemotherapy followed by localised radiotherapy is standard treatment for patients with early stage Hodgkin lymphoma (HL). However, due to long term adverse effects such as secondary malignancies, the role of radiotherapy has been questioned recently and some clinical study groups advocate chemotherapy only for this indication. OBJECTIVES We performed a systematic review with meta-analysis of randomised controlled trials (RCTs) comparing chemotherapy alone with CMT in patients with early stage Hodgkin lymphoma with respect to response rate, progression-free survival (alternatively tumour control) and overall survival (OS). SEARCH STRATEGY We searched MEDLINE, EMBASE and CENTRAL as well as conference proceedings from January 1980 to November 2010 for randomised controlled trials comparing chemotherapy alone to the same chemotherapy regimen plus radiotherapy. SELECTION CRITERIA Randomised controlled trials comparing chemotherapy alone with CMT in patients with early stage HL. Trials in which the chemotherapy differed between treatment arms were excluded. Trials with more than 20% of patients in advanced stage were also excluded. DATA COLLECTION AND ANALYSIS Effect measures used were hazard ratios (HR) for tumour control and OS as well as relative risks for response rates. Two review authors independently extracted data and assessed quality of trials. We contacted study authors to obtain missing information. Since none of the trials reported progression-free survival according to our definitions, all similar outcomes were evaluated as tumour control. MAIN RESULTS Five RCTs involving 1245 patients were included. The HR was 0.41 (95% confidence interval (CI) 0.25 to 0.66) for tumour control and 0.40 (95% CI 0.27 to 0.61) for OS for patients receiving CMT compared to chemotherapy alone. Complete response rates were similar between treatment groups. In sensitivity analyses another six trials were included that did not fulfil the inclusion criteria of our protocol but were considered relevant to the topic. These trials underlined the results of the main analysis. AUTHORS' CONCLUSIONS Adding radiotherapy to chemotherapy improves tumour control and overall survival in patients with early stage Hodgkin lymphoma.

Declining use of radiotherapy in stage I and II Hodgkin's disease and its effect on survival and secondary malignancies. Int J Radiat Oncol Biol Phys 2011; 82:619-25. [PMID: 22251881 DOI: 10.1016/j.ijrobp.2010.10.069] [Citation(s) in RCA: 40] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2010] [Revised: 10/05/2010] [Accepted: 10/13/2010] [Indexed: 02/06/2023]
Abstract
PURPOSE Concerns regarding long-term toxicities have led some to withhold radiotherapy (RT) for the treatment of Stage I and II Hodgkin's disease (HD). The present study was undertaken to assess the use of RT for HD and its effect on overall survival and the development of secondary malignancies. METHODS AND MATERIALS The present study included data from the Surveillance, Epidemiology, and End Results database from patients aged ≥ 20 years who had been diagnosed with Stage I or II HD between 1988 and 2006. Overall survival was estimated using the Kaplan-Meier method, and the Cox multivariate regression model was used to analyze trends. RESULTS A total of 12,247 patients were selected, and 51.5% had received RT. The median follow-up for the present cohort was 4.9 years, with 21% of the cohort having >10 years of follow-up. Between 1988 and 1991, 62.9% had undergone RT, but between 2004 and 2006, only 43.7% had undergone RT (p < .001). The 5-year overall survival rate was 76% for patients who had not received RT and 87% for those who had (p < .001). The hazard ratio adjusted for other variables in the regression model showed that patients who had not undergone RT (hazard ratio, 1.72; 95% confidence interval, 1.72-2.02) was associated with significantly worse survival compared with patients who had received RT. The actuarial rate of developing a second malignancy was 14.6% vs. 15.0% at 15 years for those who had and had not undergone RT, respectively (p = .089). CONCLUSIONS The present study is one of the largest studies to examine the role of RT for Stage I and II HD. Our results revealed a survival benefit with the addition of RT with no increase in the development of secondary malignancies compared with patients who had not received RT. Furthermore, the present nationwide study revealed a >20% absolute decrease in the use of RT from 1988 to 2006.

Abstract
PURPOSE The increased risk of breast cancer (BC) among women receiving chest radiotherapy for Hodgkin's lymphoma (HL) is well-established. However, there are no large population-based studies that describe overall survival (OS) and cause-specific survival (CSS) compared with women with first primary BC. METHODS For 298 HL survivors who developed BC (HL-BC group) and 405,223 women with a first or only BC (BC-1 group), actuarial OS and CSS were compared, accounting for age, BC stage, hormone receptor status, sociodemographic status, radiation for HL, and other variables. All patients were derived from the population-based Surveillance, Epidemiology, and End Results program. RESULTS OS among patients with HL-BC was significantly inferior that of to patients with BC-1: 15-year OS was 48% versus 69% (P < .0001) for localized BC, and 33% versus 43% (P < .0001) for regional/distant BC. Patients with HL-BC had a significantly increased seven-fold risk (P < .0001) of death from other cancers (ie, not HL or BC) compared with patients with BC-1. Mortality from heart disease among patients with HL-BC with either localized or regional/distant disease was also significantly increased (hazard ratio = 2.22, P = .04; and hazard ratio = 4.28, P = .02, respectively) compared with patients with BC-1. Although 10-year BC-CSS was similar for patients with HL-BC and BC-1 with regional/distant disease, it was inferior for patients with localized BC (82% v 88%, respectively; P = .002). CONCLUSION Women with HL may survive a subsequent diagnosis of BC, only to experience significant excesses of death from other primary cancers and cardiac disease. Greater awareness of screening for cardiac disease and subsequent primary cancers in patients with HL-BC is warranted.

Abstract
The incidence of the myelodysplastic syndromes (MDS) in the United States is reported as 3.4 per 100,000 people, translating to over 10,000 new diagnoses annually. This figure is considered to be an underestimate as our data capture techniques improve, and probably translates to a prevalence of approximately 60,000 people or more living with the disease. Patients are in their seventh or eighth decades at diagnosis, typically present with cytopenias, and have substantive transfusion requirements. The most common risk factors for developing MDS include advanced age, male gender, previous exposure to chemotherapy or radiation therapy, smoking, or, in rare cases, exposure to industrial chemicals.

Abstract
PURPOSE A comparative treatment planning study was performed to compare volumetric-modulated arc (RA) to conventional intensity modulated (IMRT) for involved-field (IFRT) and involved-node (INRT) radiotherapy for Hodgkin lymphoma (HL). METHODS AND MATERIALS Plans for 10 early-stage HL female patients were computed for RA and IMRT. First, the planning target volume (PTV) coverage and organs at risk (OAR) dose deposition was assessed between the two modalities. Second, the OAR (lung, breast, heart, thyroid, and submandibular gland) dose-volume histograms were computed and compared for IFRT and INRT, respectively. RESULTS For IFRT and INRT, PTV coverage was equally homogeneous with both RA and IMRT. By and large, the OAR irradiation with IFRT planning was not significantly different between RA and IMRT. For INRT, doses computed for RA were, however, usually lower than those with IMRT, particularly so for the lung, breast, and thyroid. Regardless of RA and IMRT modalities, a significant 20-50% decrease of the OAR computed mean doses was observed with INRT when compared with IFRT (Breast D(Mean) 1.5 +/- 1.1 vs. 2.6 +/- 1.7 Gy, p < 0.01 and 1.6 +/- 1.1 vs. 2.9 +/- 1.9 Gy, p < 0.01 for RA and IMRT, respectively). CONCLUSIONS RA and IMRT results in similar level of dose homogeneity. With INRT but not IFRT planning, the computed doses to the PTV and OAR were usually higher and lower with RA when compared to IMRT. Regardless of the treatment modality, INRT when compared with IFRT planning led to a significant decrease in OAR doses, particularly so for the breast and heart.

In sensitivity analyses another 6 trials were included that did not fulfill the inclusion criteria of our protocol but were considered relevant to the topic. These trials underlined the results of the main analysis. In conclusion, adding radiotherapy to chemotherapy improves tumor control and OS in patients with early stage Hodgkin's lymphoma.

Abstract
This study estimated the risk of second primary malignancies after Hodgkin's lymphoma (HL) in relation to family history of cancer, age at diagnosis and latency, among 6946 patients treated for HL in Sweden in 1965-1995 identified through the Swedish Cancer Register (SCR). First-degree relatives (FDRs) to the HL patients and their malignancies were then ascertained together with their malignancies through the Multi-Generation Registry and SCR. The HL patient cohort was stratified on the number of FDRs with cancer, and standardised incidence ratios (SIRs) of developing SM were analysed. In the HL cohort, 781 SM were observed 1 year or longer after HL diagnosis. The risk for developing SM increased with the number of FDRs with cancer, SIRs being 2.26, 3.01, and 3.45 with 0, 1, or >or=2 FDRs with cancer, respectively. Hodgkin's lymphoma long-term survivors treated at a young age with a family history of cancer carry an increased risk for developing SM and may represent a subgroup where standardised screening for the most common cancer sites could be offered in a stringent surveillance programme.

Abstract
The outcome of patients who have early unfavorable or intermediate-stage Hodgkin's lymphoma has greatly improved. The increasing efficacy of chemotherapy and late toxic effects of wide-field radiotherapy justify the careful testing of the new involved-node radiotherapy principle in the combined-modality approach. For the purpose of tailoring treatment to the individual patient we need more accurate measures, preferably predictive factors that may tell us how the individual patient should be treated. The result of an early positron emission tomography scan with fluorodeoxyglucose may well become the major new treatment-related guidance for an individually tailored treatment approach.

Abstract
In recent years, radiotherapy in patients with Hodgkin lymphoma has evolved considerably because of sophisticated imaging technologies and radiation delivery techniques. Even more recently, a new radiation field concept has emerged to ensure better normal tissue protection while preserving an excellent clinical outcome. The role of radiation therapy is also rapidly changing because the concept of a risk-adapted treatment strategy, in which combined-modality treatments were the order of the day, is now expanding into a concept of response-adapted treatments.

Abstract
PurposeTo investigate whether combined-modality treatment (CMT) with two cycles of doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) followed by extended-field radiotherapy (EF-RT) is superior to EF-RT alone in patients with early favorable Hodgkin's lymphoma (HL).Patients and MethodsBetween 1993 and 1998, 650 patients with newly diagnosed, histology-proven HL in clinical stages IA to IIB without risk factors were enrolled onto this multicenter study and randomly assigned to receive 30 Gy EF-RT plus 10 Gy to the involved field (arm A) or two cycles of ABVD followed by the same radiotherapy (arm B).ResultsAt a median observation time of 87 months, there was no difference between treatment arms in terms of complete response rate (arm A, 95%; arm B, 94%) and overall survival (at 7 years: arm A, 92%; arm B, 94%; P = .43). However, freedom from treatment failure was significantly different, with 7-year rates of 67% in arm A (95% CI, 61% to 73%) and 88% in arm B (95% CI, 84% to 92%; P ≤ .0001). This was due mainly to significantly more relapses after EF-RT only (arm A, 22%; arm B, 3%). No patient treated with CMT experienced relapse before year 3. Relapses were treated mainly with bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone, or with the combination cyclophosphamide, vincristine, procarbazine, and prednisone/ABVD; treatment of relapse was significantly more successful in arm A than in arm B (P = .017). In total, there were 39 second malignancies, with 21 in arm A and 18 in arm B, respectively. The incidence was approximately 0.8% per year during years 2 to 9 and was highest in older patients (P < .0001) and those with “B” symptoms (P = .012).ConclusionCMT consisting of two cycles of ABVD plus EF-RT is more effective than EF-RT alone.

Abstract
AbstractFrom 1989 to 1996, 533 eligible patients with stage IIIB/IV Hodgkin lymphoma (HL) were randomly assigned to receive 6 cycles of hybrid MOPP/ABV (mechlorethamine, vincristine, procarbazine, prednisone/Adriamycin [doxorubicin], bleomycin, vinblastine; n = 266) or ABVPP (doxorubicin, bleomycin, vinblastine, procarbazine, prednisone; n = 267). Patients in complete remission (CR) or partial response of at least 75% after 6 cycles received 2 cycles of consolidation chemotherapy (CT) (n = 208) or subtotal nodal irradiation (RT) (n = 210). A better survival probability was observed after ABVPP alone: the 10-year overall survival (OS) estimates were 90% for ABVPP×8, 78% for MOPP/ABV×8, 82% for MOPP/ABV with RT, and 77% for ABVPP×6 with RT (P = .03); and the 10-year disease-free survival (DFS) estimates were 70%, 76%, 79%, and 76%, respectively (P = .09). The 10-year DFS estimates for patients treated with consolidation CT or RT were 73% and 78% (P = .07), and OS estimates were 84% and 79%, respectively (P = .29). These results showed that RT was not superior to consolidation CT after a doxorubicin-induced CR in patients with advanced HL. An analysis of competing risks identified age more than 45 years as a significant risk factor for death, relapse, and second cancers. Prospective evaluation of late adverse events may improve the management of patients with HL.
