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.

BACKGROUND
Oligodendrogliomas (ODG) are rare, diffusely infiltrating brain tumors, defined by their 1p/19q-codeletion and isocitrate dehydrogenase (IDH) mutation. Herein, we analyze the influence of various tumor and patient characteristics on progression-free survival (PFS) and overall survival (OS) in a homogeneous patient cohort.
MATERIAL AND METHODS
Patients treated for a 1p/19q-codeleted and IDH-mutant ODG were evaluated. The patient and tumor characteristics were analyzed for their influence on PFS and OS.
RESULTS
One-hundred-fourteen patients met the inclusion criteria. The median clinical and radiographic follow-up periods were 68.6 and 69.8 months. The median PFS and OS were 66.9 and 236.0 months, respectively. The 2-, 4- and 6-year PFS rates were 89.5%, 76.3%, and 46.0%. The 2-, 4- and 6-year OS rates were 99.0%, 97.9%, and 96.2%. For WHO grade 2 ODG, extent of resection ( 0.01, 0.01; 0.02, 0.02), radiotherapy ( 0.01, < 0.01) and chemotherapy ( 0.01, 0.01) were associated with a prolonged PFS. For WHO grade 3 ODG, only a combined radiochemotherapy (RCT) lowered the risk of progression in the multivariable analysis ( = 0.02, 0.09). Most RCT patients received temozolomide (TMZ) instead of procarbazine, lomustine, and vincristine.
CONCLUSION
Whereas previous studies often comprise tumors with IDH wild type status and without 1p/19q-codeletion, this homogeneous ODG cohort, as defined by the current WHO classification, demonstrated PFS benefits for various therapies, especially concerning RCT. While this is generally in accordance with comparable studies, more prospective work on homogeneous patient cohorts is required to refine treatment guidelines and to determine the role of TMZ in ODG.

The present retrospective study was undertaken to investigate the association of relative dose intensity (RDI) with the outcome of patients with advanced stage Hodgkin lymphoma (HL) receiving ABVD (doxorubicin, bleomycin, vinblastine, dacarbazine) and escalated BEACOPP regimens (bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, prednisone). A total of 114 patients with HL treated between 2004 and 2013 were enrolled for evaluation. The association of variables with overall survival (OS) and progression-free survival (PFS) was analysed using univariate and multivariate Cox proportional hazards models. The median age of patients was 39 years, and the majority were male and had stage IV disease. A total of 54 patients received ABVD and 60 received BEACOPP chemotherapy with 24 and four deaths, respectively. Patients in the BEACOPP group were significantly younger with lower Charlson comorbidity index (CCI) and better performance status in comparison with the ABVD group, making the comparison of groups not possible. In the ABVD group, RDI was not significantly associated with OS (P=0.590) or PFS (P=0.354) in a multivariate model where age was controlled. The low number of events prevented this analysis in the BEACOPP group. The age of patients was strongly associated with both OS and PFS; all statistically significant predictors for OS and PFS from univariate analyses (chemotherapy regimen, CCI, RDI, performance status) lost their effect in multivariate analyses where age was controlled. Based on these observations, it was concluded that RDI was not associated with OS or PFS after age is controlled, neither in all patients combined nor in the ABVD group.

Journal of B.U.ON. : Official Journal... 2021To assess the efficacy and tolerance of proton re-irradiation in patients with unresectable recurrence of previously irradiated brain gliomas.
PURPOSE
To assess the efficacy and tolerance of proton re-irradiation in patients with unresectable recurrence of previously irradiated brain gliomas.
METHODS
Between February 2016 and December 2019, 44 patients with in-field recurrence after prior irradiation of brain gliomas were irradiated with intensity-modulated proton therapy. Seven patients (15.9%) originally had low-grade (WHO grade I-II) gliomas, nine patients (20.4%) had anaplastic astrocytoma (WHO grade III), and 28 patients (63.7%) had glioblastoma (WHO grade IV). All tumors were unresectable due to their localization. After a median time from the prior irradiation of 28.0 months [range, 12 to 173], patients received PT with 2.0 and 3.0 GyRBE per fraction, with median proton EQD2 (/=10) to a tumor of 55.0 GyRBE [range, 46.0 to 61.75]. Adjuvant chemotherapy (Temozolomide, or Procarbazine, Lomustine and vincristine, or Bevacizumab with Irinotecan) received 86.9% of the patients (n=40). Treatment-related toxicity was reported following CTCAE.
RESULTS
The median survival time was 12 months, with 1-year and 2-years overall survival (OS) amounting to 49.6% and 35.1%, respectively. The median progression-free survival (PFS) was 9 months, with 1- and 2-years PFS of 30.5% and 10.2%, respectively. Twenty-six patients died by the time of analysis; among them were 5 non-cancer deaths (19.2%), and 4 patients (15.4%) died of chemotherapy-associated severe toxicity. The incidence rate of radiation-induced necrosis was 6.8% (3 events).
CONCLUSIONS
Based on our results, we suggest re-irradiation of recurrent brain gliomas with proton therapy is able to achieve reasonable tumor control. Low adverse events rate and promising outcomes make it a safe treatment option with curative intent, even in unresectable cases.

PURPOSE
Patients with bulky stage I/II classic Hodgkin lymphoma (cHL) are typically treated with chemotherapy followed by radiation. Late effects associated with radiotherapy include increased risk of second cancer and cardiovascular disease. We tested a positron emission tomography (PET)-adapted approach in patients with bulky, early-stage cHL, omitting radiotherapy in patients with interim PET-negative (PET-) disease and intensifying treatment in patients with PET-positive (PET+) disease.
METHODS
Eligible patients with bulky disease (mass > 10 cm or 1/3 the maximum intrathoracic diameter on chest x-ray) received two cycles of doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) followed by interim fluorodeoxyglucose PET (PET2). Patients with PET2-, defined as 1-3 on the 5-point scale, received four additional cycles of doxorubicin, bleomycin, vinblastine, and dacarbazine. Patients with PET2+ received four cycles of escalated bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone followed by 30.6 Gy involved-field radiation.
RESULTS
Of 94 evaluable patients, 53% were female with median age 30 years (range, 18-58 years). Eight-five (90%) had stage II disease, including 48 (51%) with stage IIB/IIBE. Seventy-eight (78%) were PET2- and 21 (22%) were PET2+. The predominant toxicity was neutropenia, with 9% of patients developing febrile neutropenia and one developing sepsis. The primary end point of 3-year progression-free survival (PFS) was 93.1% in PET2- and 89.7% in PET2+ patients. Three-year overall survival was 98.6% and 94.4%, respectively. The estimated hazard ratio comparing PFS of patients with PET2+ and patients with PET2- was 1.03 (85% upper bound 2.38) and was significantly less than the null hypothesis of 4.1 (one-sided = .04).
CONCLUSION
Our study of PET-adapted therapy in bulky stage I/II cHL met its primary goal and was associated with an excellent 3-year PFS rate of 92.3% in all patients, with the majority being spared radiotherapy and exposure to intensified chemotherapy.

Objective Few reports have described the real-world outcomes of rituximab, methotrexate (MTX), procarbazine, and vincristine (R-MPV) plus response-adapted whole-brain radiotherapy (WBRT) for elderly patients with primary central nervous system lymphoma (PCNSL). We evaluated the outcome of this regimen. Methods We evaluated >60-year-old patients with newly diagnosed PCNSL who received R-MPV plus WBRT from January 2010 to December 2019 at Toyohashi Municipal Hospital. The patients' characteristics, regimen enforcement, response rate, survival, and toxicity were analyzed. Patients Ten patients were consecutively enrolled. Their median age was 69 years old, and 60% had a performance status of 3 or 4 before induction therapy. Results Seven patients achieved a complete response after induction, and all 10 patients achieved a complete response after consolidation. Seven received reduced-dose WBRT at 23.4 Gy, and 2 received WBRT at 45 Gy. The median follow-up was 44.4 months; the 3-year progression-free survival and overall survival rates were 60% and 80%, respectively; and the cumulative incidence of relapse was 40%. The incidence of symptomatic delayed neurotoxicity was 70%. Of the 7 patients who received reduced-dose WBRT, 4 (57%) developed delayed neurotoxicity, including 1 severely affected patient. Only one patient survived without relapse and delayed neurotoxicity. The ratio of patients who developed relapse or delayed neurotoxicity that impaired daily life was 33% and 100% in the MTX high- and low-intensity groups, respectively. Conclusion This regimen in elderly patients is unsatisfactory because of delayed neurotoxicity. We should consider maintaining an adequate MTX intensity, postponing or minimizing WBRT, and choosing high-dose consolidation therapy for select patients.

The Radiation Therapy Oncology Group (RTOG) 9310 protocol clinical trial established high-dose methotrexate (HDMTX) as the standard for primary central nervous system lymphoma (PCNSL). We aimed to investigate the RTOG 9310 protocol's PCNSL outcomes by examining progression-free survival (PFS) and overall survival (OS) rates and determining the influential factors. Between 2007 and 2020, 87 patients were histopathologically diagnosed with PCNSL and treated with the RTOG 9310 protocol. All received HDMTX 2.5 g/m and vincristine 1.4 mg/m/day for 1 day during weeks 1, 3, 5, 7, and 9, and procarbazine 100 mg/m/day for 1 day during weeks 1, 5, and 9. Dexamethasone was administered on a standard tapering schedule from the first week to the sixth week. Whole brain radiotherapy (WBRT), consisting of 45 Gy for patients with less than a complete response to the chemotherapy or 36 Gy for complete responders, was started 1 week after the last dose of chemotherapy was administered. Within three weeks of the completion of WBRT, patients received two courses of cytarabine, which were separated by 3-4 weeks. Clinical, radiological, and histopathological characteristics were retrospectively reviewed. All patients completed five HDMTX cycles and a mean follow-up of 60.2 (range, 6-150) months. Twenty-eight (32.2%) patients experienced recurrence during follow-up. The mean time to recurrence was 21.8 months, while the mean PFS was 104.3 (95% confidence interval (CI), 90.6-118.0) months. Eleven (12.6%) patients died; the mean OS was 132.1 (95% CI, 122.2-141.9) months. The 3- and 5-year survival rates were 92.0% and 87.4%, respectively. One patient experienced acute renal failure, while the remainder tolerated any cytotoxic side effects. On multivariate analysis, the Eastern Cooperative Oncology Group performance score ≤ 2; the International Extranodal Lymphoma Study Group low-risk status; XBP-1, p53, and c-Myc negativity; homogenous enhancement; gross total resection, independently correlated with long PFS and OS. The RTOG 9310 protocol is effective for PCNSL and features good outcomes.

Hodgkin lymphoma (HL) treatment increases the risk of lung cancer. Most HL survivors are not eligible for lung cancer screening (LCS) programmes developed for the general population, and the utility of these programmes has not been tested in HL survivors. We ran a LCS pilot in HL survivors to describe screening uptake, participant characteristics, impact of a decision aid and screen findings. HL survivors treated ≥5 years ago with mustine/procarbazine and/or thoracic radiation, were identified from a follow-up database and invited to participate. Participants underwent a low-dose CT (LDCT) reported using protocols validated for the general population. Two hundred and eighteen individuals were invited, 123 were eligible, 102 were screened (58% response rate): 58% female, median age 52 years, median 22 years since HL treatment. 91.4% were deemed to have made an informed decision; participation was not influenced by age, gender, years since treatment or deprivation. Only 3/35 ever-smokers met criteria for LCS through the programme aimed at the general population. Baseline LDCT results were: 90 (88.2%) negative, 10 (9.8%) indeterminate, 2 (2.0%) positive. Two 3-month surveillance scans were positive. Of 4 positive scans, 2 patients were diagnosed with small-cell lung cancer; 1 underwent curative surgery. Coronary artery calcification was detected in 36.3%, and clinically significant incidental findings in 2.9%. LDCT protocols validated in ever-smokers can detect asymptomatic early-stage lung cancers in HL survivors. This finding, together with screening uptake and low false positive rates, supports further research to implement LCS for HL survivors.

The present study aimed to evaluate the stability of active pharmaceutical ingredients (APIs) from different pharmacological classes in a compounded oral suspending vehicle. Oral suspensions of amoxicillin trihydrate (50 mg/mL), clozapine (25 mg/mL), indomethacin (5.0 mg/mL), levodopa/carbidopa (10.0/2.5 mg/mL), levothyroxine sodium (T4, 25 µg/mL), lomustine (4.0 and 10.0 mg/mL), methyldopa (25 mg/mL) and procarbazine (10.0 mg/mL) were formulated in SyrSpend SF PH4 and the stability was monitored for up to 90 days, except for amoxicillin trihydrate, which was evaluated for 30 days only. The APIs' stability was determined by measuring percent recovery using stability-indicating high-performance liquid chromatography (HPLC or UHPLC) or titration (amoxicillin trihydrate only). The stability of amoxicillin trihydrate, clozapine, indomethacin and levodopa/carbidopa were studied at both refrigerated (2-8 °C) and room temperature (20-25 °C). Lomustine, procarbazine, and methyldopa were studied at refrigerated temperature only. Our data demonstrated promising stability for the compounded suspensions containing various APIs, investigated in SyrSpend SF PH4, as all APIs exhibited stability throughout the study duration and met content uniformity criteria. These findings lead to the conclusion that the tested compounded oral suspensions present a viable approach for creating personalized, age-appropriate formulations. The capacity to ensure dose consistency and stability using APIs from diverse pharmacological classes renders them suitable choices for both pediatric and geriatric patients.

PEP-C (prednisolone, etoposide, procarbazine and cyclophosphamide) is an orally administered daily chemotherapy regimen used with palliative intent in relapsed refractory lymphoma. To our knowledge, no data on PEP-C have been reported since the original group described the regimen. Here we present a multicentre retrospective cohort reporting our use of PEP-C in 92 patients over an 8-year period. We find that even heavily pretreated lymphoma can respond to PEP-C, particularly low-grade lymphoma (including mantle cell) and lymphoma that was sensitive to the previous line of systemic therapy (chemosensitive). These characteristics may help in the selection of patients likely to derive benefit. The median overall survival of patients with chemosensitive lymphoma treated with PEP-C is 217 days. Within the limitations of a retrospective cohort, we find that PEP-C is well tolerated: the most common toxicity leading to discontinuation is marrow suppression. We suggest that PEP-C should be considered for patients with relapsed refractory lymphoma in two settings: first, where there is no licensed alternative; and second, where the licensed alternative is an intravenous drug and the patient would prefer to choose an oral chemotherapy option.
