Procarbazine, lomustine and vincristine (PCV) chemotherapy is considered a salvage option for adult glioma; however, its significant toxicities frequently lead to dose reduction or discontinuation in patients with recurrent glioma. The current study evaluated the safety and efficacy of modified procarbazine and lomustine (PC) chemotherapy that omits vincristine and reduces the lomustine dose compared with those of conventional PCV chemotherapy. Using electronic medical records, all patients with adult recurrent glioma who received PC or PCV chemotherapy between 2009 and 2020 at Seoul St. Mary's Hospital or St. Vincent's Hospital were examined retrospectively. A total of 59 patients met the eligibility criteria. Among them, 15 patients received modified PC chemotherapy (PC group) and 44 patients received PCV chemotherapy (PCV group). The PC group presented a significantly lower hematology toxicity (anemia, 6.7 vs. 45.5%, P=0.02; thrombocytopenia 20.0 vs. 70.4%, P<0.001). Additionally, the clinical impacts of PC chemotherapy, including delay of a cycle, dose reduction, discontinuation of drug(s) or total cessation of chemotherapy, were significantly less frequent compared with the PCV group (26.7 vs. 68.2%, P=0.012). The overall survival of the PC group was also significantly longer than that of PCV group (396 vs. 232 days, P=0.042), while there was no significant difference in progression-free survival between the two groups (284.5 vs. 131 days, P=0.077). The results suggested that modified PC chemotherapy may be an alternative chemotherapeutic regimen with tolerable toxicity and without loss of clinical efficacy in patients with recurrent adult glioma. Further prospective and larger studies are required to validate our findings.

BACKGROUND
Hodgkin's lymphoma (HL) can be treated with combined modality treatment (CMT) to limit long-term toxicities in the early favorable stage. Early unfavorable and advanced stage HL is mainly treated with chemotherapy followed by radiation to the bulky site. This study examines the impact of CMT in early as well as advanced stage HL.
MATERIALS AND METHODS
From 2001 to 2011, 125 patients with Stage I to IV HL were analyzed. Median age of the patients was 25 years (range 12-68 years). CMT, chemotherapy, and radiation alone were given to 51, 64, and 10 patients, respectively. Chemotherapy with doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) was given to 100 patients, 6 patients received ABVD-like regimen, and 9 patients received cyclophosphamide, vincristine, procarbazine, and prednisone regimen. Radiotherapy (RT) was given to 61 (49%) patients, involved field RT to 55 (90%), and extended-field RT to 6 (10%) patients, respectively. Median radiation dose was 30 Gy (18-40 Gy).
RESULTS
All 25 patients with early-stage achieved complete response (CR) with CMT. At a median follow-up of 70 months (range 12-230 months), relapse was seen in two patients (1 local and 1 distant). Of 26 patients with advanced stage, 25 achieved a CR and 1 had stable disease with CMT. Relapse occurred in one patient (distant). In patients with early-stage treated with chemotherapy only ( n = 30, 24%), 9 patients had relapse (4 local and 5 distant) while in those with RT only ( n = 10, 8%), 4 developed distant relapse. In patients with advanced stage treated with chemotherapy only ( n = 34, 27%), 8 relapsed (5 local and distant, 3 distant only). Patients with relapse were salvaged with CMT ( n = 6), chemotherapy ( n = 15), or RT ( n = 3). Two patients have died. Five years' disease-free survival (DFS) in patients with early favorable stage, early unfavorable stage, and advanced stage was 91%, 82%, and 73%, respectively ( P = 0.026). DFS was significantly better with CMT than chemotherapy or radiation alone. Five years' overall survival (OS) was 93%, 92%, and 84%, respectively ( P = 0.139). Second malignancy occurred in 3 (2.4%) patients; carcinoma of the tongue, pseudomyxoma peritonei, and non-HL each, respectively. None of these patients had received prior radiation.
CONCLUSION
CMT improved DFS in patients with HL. OS was similar in all patients irrespective of treatment combinations. The incidence of second malignancy was 2.4%.

Review
Gliomas are a group of heterogeneous tumors that account for substantial morbidity, mortality, and costs to patients and healthcare systems globally. Survival varies considerably by grade, histology, biomarkers, and genetic alterations such as IDH mutations and promoter methylation, and treatment, but is poor for some grades and histologies, with many patients with glioblastoma surviving less than a year from diagnosis. The present review provides an introduction to glioma, including its classification, epidemiology, economic and humanistic burden, as well as treatment options. Another focus is on treatment recommendations for IDH-mutant astrocytoma, IDH-mutant oligodendroglioma, and glioblastoma, which were synthesized from recent guidelines. While recommendations are nuanced and reflect the complexity of the disease, maximum safe resection is typically the first step in treatment, followed by radiotherapy and/or chemotherapy using temozolomide or procarbazine, lomustine, and vincristine. Immunotherapies and targeted therapies currently have only a limited role due to disappointing clinical trial results, including in recurrent glioblastoma, for which the nitrosourea lomustine remains the standard of care. The lack of treatment options is compounded by frequently suboptimal clinical practice, in which patients do not receive adequate therapy after resection, including delayed, shortened, or discontinued radiotherapy and chemotherapy courses due to treatment side effects. These unmet needs will require significant efforts to address, including a continued search for novel treatment options, increased awareness of clinical guidelines, improved toxicity management for chemotherapy, and the generation of additional and more robust clinical and health economic evidence.

Hodgkin lymphoma (HL) in older patients, commonly defined as ≥60 years of age, is a disease for which survival rates have historically been significantly lower compared with younger patients. Older HL patients appear to have different disease biology compared with younger patients, including increased incidence of mixed cellularity histology, Epstein-Barr virus-related, and advanced-stage disease. For prognostication, several studies have documented the significance of comorbidities and functional status in older HL patients, as well as the importance of achieving initial complete remission. Collectively, selection of therapy for older HL patients should be based in part on functional status, including pretreatment assessment of activities of daily living (ADL), comorbidities, and other geriatric measures (eg, cognition, social support). Treatment of fit older HL patients should be given with curative intent, regardless of disease stage. However, attention should be paid to serious treatment-related toxicities, including risk of treatment-related mortality. Although inclusion of anthracycline therapy is important, bleomycin-containing regimens (eg, doxorubicin, bleomycin, vinblastine, dacarbazine) may lead to prohibitive pulmonary toxicity, and intensive therapies (eg, bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, prednisone) are too toxic. Brentuximab vedotin given sequentially before and after doxorubicin, vinblastine, and dacarbazine to fit, untreated advanced-stage older HL patients was recently shown to be tolerable and highly effective. Therapy for patients who are unfit or frail because of comorbidities and/or ADL loss is less clear and should be individualized with consideration of lower-intensity therapy, such as brentuximab vedotin with or without dacarbazine. Altogether, therapy for older HL patients should be tailored based upon a geriatric assessment, and novel targeted agents should continue to be integrated into treatment paradigms.

T2-Fluid-attenuated inversion recovery (FLAIR) pseudoprogression in patients with anaplastic oligodendrogliomas treated with procarbazine, lomustine and vincristine (PCV) chemotherapy alone.
BACKGROUND
Pseudoprogression in gliomas has been extensively described after radiotherapy with or without chemotherapy, but not after chemotherapy alone. Here we describe the occurrence of pseudoprogression in patients with anaplastic oligodendrogliomas treated with postoperative procarbazine, lomustine and vincristine (PCV) chemotherapy alone.
METHODS
We retrospectively reviewed the medical and radiological files of patients with 1p/19q codeleted, IDH-mutant anaplastic oligodendrogliomas treated with PCV chemotherapy alone who presented magnetic resonance imaging (MRI) modifications suggestive of tumour progression and in whom the final diagnosis was a pseudoprogression.
RESULTS
We identified six patients. All patients underwent a surgical resection and were treated with PCV chemotherapy without radiotherapy. After a median of 11 months following the initiation of chemotherapy (range: 3-49 months), the patients developed asymptomatic white matter MRI modifications around the surgical cavity leading to the suspicion of a tumour progression. These modifications appeared as hyperintense on T2-fluid-attenuated inversion recovery (FLAIR) sequence, hypointense on T1 sequence, and lacked mass effect (0/6), contrast enhancement (0/6), restriction on diffusion-weighted imaging (0/4), relative cerebral blood volume (rCBV) increase on perfusion MRI (0/4), and hypermetabolism on F-fluoro-L-dopa positron emission tomography ( F-DOPA PET) scan (0/3). One patient underwent a surgical resection demonstrating no tumour recurrence; the five other patients were considered as having post-therapeutic modifications based on imaging characteristics. After a median follow-up of 4 years all patients were progression-free.
CONCLUSIONS
Anaplastic oligodendroglioma patients treated with postoperative PCV chemotherapy alone occasionally develop T2/FLAIR hyperintensities around the surgical cavity that can wrongly suggest tumour progression. Multimodal imaging and close follow-up should be considered in this situation.

FRONTLINE THERAPY FOR CLASSICAL HODGKIN LYMPHOMA PATIENTS. Upfront first-line chemotherapy is indicated for all features of classical Hodgkin's lymphoma, followed by involved node radiotherapy in early stages; the ABVD protocol (doxorubicin (Adriamycin), bleomycin, vinblastine, dacarbazine) is the international standard of care. The 7-agent BEACOPP protocol (bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine (Oncovin), procarbazine, prednisone) is used in advanced stages in its «escalated» version (BEAesc). During the 2010 decade, it has been demonstrated that strategies guided by positron emission tomography (PET) allows optimizing the benefit/risk ratio of the treatment by decreasing the intensity of therapies for good responders and intensifying treatment of poor responders. Thus, early PET response evaluation is now essential to adapt the treatment intensity. Despite these major advances, several issues remain, including the management of acute and long-term side effects of first-line treatments, the better options for refractory patients, the place and optimization of radiotherapy, and the place for new therapeutic agents such as the anti-CD30 conjugate antibody (brentuximab vedotin) and PD-1 inhibitors in the first-line treatment setting.

Comparative Study Review
PURPOSE
We explored the potential overall survival (OS) benefit of bleomycin, etoposide, doxorubicin (Adriamycin), cyclophosphamide, vincristine (Oncovin), procarbazine, and prednisone (BEACOPP) over doxorubicin (Adriamycin), bleomycin, vinblastine, and dacarbazine (ABVD) in a pooled analysis of four randomized trials.
PATIENTS AND METHODS
Primary objective was to evaluate the OS impact of BEACOPP using individual patient data. Secondary objectives were progression-free survival (PFS), secondary cancers, and use of autologous stem cell transplantation (ASCT).
RESULTS
About 1227 patients were included. The 7-year OS was 84.3% (95% CI 80.8-87.2) for ABVD vs 87.7% (95% CI 84.5-90.2) for BEACOPP. Two follow-up periods were identified based on survival curves and hazard ratio (HR) over time. For the first 18 months, there was no difference. For the second period of ≥18 months, ABVD patients had a higher death risk (HR = 1.59; 95% CI 1.09-2.33). A Cox model stratified by trial and evaluating the effect of treatment and International Prognostic Index (IPI) score as fixed effects showed that both were statistically significant (treatment, P = .0185; IPI score, P = .0107). The 7-year PFS was 71.1% (95% CI 67.1-74.6) for ABVD vs 81.1% (95% CI 77.5-84.2) for BEACOPP (P < .001). After ABVD, 25 secondary cancers (4.0%) were reported with no myelodysplasia (MDS)/acute myeloid leukemia (AML) compared to 36 (6.5%) after BEACOPP, which included 13 patients with MDS/AML. Following ABVD, 86 patients (13.8%) received ASCT vs 39 (6.4%) for BEACOPP.
CONCLUSIONS
This analysis showed a slight improvement in OS for BEACOPP and confirmed a PFS benefit. Frontline use of BEACOPP instead of ABVD increased secondary leukemia incidence but halved the requirement for ASCT.

Randomized Controlled Trial
BACKGROUND
Given the young age of patients with CNS WHO grade 2 and 3 oligodendrogliomas and the relevant risk of neurocognitive, functional, and quality-of-life impairment with the current aggressive standard of care treatment, chemoradiation with PCV, of the tumour located in the brain optimizing care is the major challenge.
METHODS
NOA-18 aims at improving qualified overall survival (qOS) for adult patients with CNS WHO grade 2 and 3 oligodendrogliomas by randomizing between standard chemoradiation with up to six six-weekly cycles with PCV and six six-weekly cycles with lomustine and temozolomide (CETEG) (n = 182 patients per group accrued over 4 years) thereby delaying radiotherapy and adding the chemoradiotherapy concept at progression after initial radiation-free chemotherapy, allowing for effective salvage treatment and delaying potentially deleterious side effects. QOS represents a new concept and is defined as OS without functional and/or cognitive and/or quality of life deterioration regardless of whether tumour progression or toxicity is the main cause. The primary objective is to show superiority of an initial CETEG treatment followed by partial brain radiotherapy (RT) plus PCV (RT-PCV) at progression over partial brain radiotherapy (RT) followed by procarbazine, lomustine, and vincristine (PCV) chemotherapy (RT-PCV) and best investigators choice (BIC) at progression for sustained qOS. An event concerning a sustained qOS is then defined as a functional and/or cognitive and/or quality of life deterioration after completion of primary therapy on two consecutive study visits with an interval of 3 months, tolerating a deviation of at most 1 month. Assessments are done with a 3-monthly MRI, assessment of the NANO scale, HRQoL, and KPS, and annual cognitive testing. Secondary objectives are evaluation and comparison of the two groups regarding secondary endpoints (short-term qOS, PFS, OS, complete and partial response rate). The trial is planned to be conducted at a minimum of 18 NOA study sites in Germany.
DISCUSSION
qOS represents a new concept. The present NOA trial aims at showing the superiority of CETEG plus RT-PCV over RT-PCV plus BIC as determined at the level of OS without sustained functional deterioration for all patients with oligodendroglioma diagnosed according to the most recent WHO classification.

BACKGROUND
Anaplastic pleomorphic xanthoastrocytoma (APXA) is a rare subtype of CNS astrocytoma. They are generally treated as high-grade gliomas; however, uncertainty exists regarding the optimal therapy. Here, we report on 3 pediatric cases of APXA.
METHODS
Our institutional database was queried for cases of APXA and 3 cases were identified. Surgical samples were processed for methylation profiling and chromosomal microarray analysis. Methylation data were uploaded to the online CNS tumor classifier to determine methylation-based diagnoses to determine copy number variations (CNVs).
RESULTS
Two patients were male, 1 female, and all were aged 12 years at diagnosis. All underwent a gross total resection (GTR) and were diagnosed with an APXA. Immunohistochemical analysis demonstrated that 2 cases were BRAF V600E positive. Methylation-based tumor classification supported the APXA diagnosis in all cases. CNV analyses revealed homozygous deletions in all and chromosome 9p loss in 2 cases. All patients received radiation therapy (54 Gy in 30 fractions) with concurrent temozolomide. Two patients received maintenance chemotherapy with temozolomide and lomustine for 6 cycles as per the Children's Oncology Group ACNS0423. The third patient recurred and went on to receive a second GTR and 6 cycles of lomustine, vincristine, and procarbazine. All are alive with no evidence of disease >4 years post-treatment completion (overall survival = 100%, event free survival = 67%).
CONCLUSIONS
The natural history and optimal treatment of this rare pediatric tumor are not well understood. This case series supports the use of adjuvant chemoradiotherapy in the treatment of APXA. The genetic landscape may be informative for optimizing treatment and prognosis.

Review
Postoperative management of lower grade gliomas (grade 2 and 3) is heterogeneous. The American Radium Society's brain malignancies panel systematically reviewed and evaluated the literature to develop consensus guidelines addressing timing of postoperative therapy, monotherapy versus combined modality therapy, type of chemotherapy used with radiotherapy, and radiotherapy dose. Thirty-six studies were included. Using consensus methodology (modified Delphi), the panel voted upon representative case variants using a 9-point appropriateness scale to address key questions. Voting results were collated to develop summarized recommendations. Following gross-total surgical resection, close surveillance is appropriate for well-selected grade 2, IDH-mutant oligodendrogliomas or astrocytomas with low-risk features. For grade 2 gliomas with high-risk features or any grade 3 glioma, immediate adjuvant therapy is recommended. When postoperative therapy is administered, radiation and planned chemotherapy is strongly recommended over monotherapy. For grade 2 and 3 IDH-mutant oligodendrogliomas and astrocytomas, either adjunctive PCV (procarbazine, lomustine, vincristine) or temozolomide is appropriate. For grade 3 IDH-mutant astrocytomas, radiotherapy followed by temozolomide is strongly recommended. The recommended radiotherapy dose for grade 2 gliomas is 45-54 Gy/1.8-2.0 Gy, and for grade 3 gliomas is 59.4-60 Gy/1.8-2.0 Gy. While multiple appropriate treatment options exist, these consensus recommendations provide an evidence-based framework to approach postoperative management of lower grade gliomas.
