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.

Orally administered daily chemotherapy offers a novel treatment approach for canine lymphoma in a population of dogs that have failed or not tolerated maximum tolerable dose chemotherapy. A multidrug oral chemotherapy protocol was designed and implemented for the treatment of 50 dogs with multicentric lymphoma with minimal side effects. The protocol consisted of oral procarbazine, prednisolone and cyclophosphamide (PPC) administered daily. Efficacy and toxicity were evaluated by clinical and laboratory evaluation. An overall response rate of 70% was achieved, with 24% and 46% of dogs having a partial and complete response, respectively, to treatment with the PPC protocol. Response to the PPC protocol (complete or partial) and age were the only factors identified as prognostic for time from initiation of the PPC chemotherapy until death. Overall, the protocol was very well tolerated with only one dog requiring protocol discontinuation due to grade 4 thrombocytopenia. Eight dogs recorded gastrointestinal toxicities, seven grade I and one grade II toxicity. These findings demonstrate that the administration of a continuous oral combination chemotherapy can provide comparable survival times in the rescue setting in dogs with multicentric lymphoma with minimal side effects.

BACKGROUND
Study RTOG 9802 in high-risk diffuse low-grade gliomas (DLGGs) showed the potential synergistic effect on survival of the procarbazine, CCNU, and vincristine (PCV) radiotherapy (RT) combination. Limited data on long-term neurocognitive impact and quality of life (QoL) have yet been reported.
PATIENTS AND METHODS
We described a monocentric series of patients treated at first line by the combination of PCV immediately followed by RT between January 01, 1982 and January 01, 2017. Radiological data were collected and included volume, velocity of diametric expansion (VDE), and MRI aspects. Long-term neurocognitive and QoL were analyzed.
RESULTS
Twenty patients fulfilled the eligibility criteria. The median response rate was 65.1% (range, 9.6%-99%) at the time of maximal VDE decrease corresponding to a median volume reduction of 79.7 cm (range, 3.1 to 174.2 cm), which occurred after a median period of 7.2 years (range, 0.3-21.9) after the end of RT. An ongoing negative VDE was measured in 13/16 patients after the end of RT, with a median duration of 6.7 years (range, 9 months-21.9 years). The median follow-up since radiological diagnosis was 17.5 years (range, 4.8 to 29.5). Estimated median survival was 17.4 years (95% CI: 12; NR). After a long-term follow-up, substantial neurotoxicity was noticed with dementia in six progression-free patients (30%), leading to ventriculo-peritoneal shunt procedures in three, and premature death in five. Thirteen patients (65%) were unable to work with disability status. Successive longitudinal neurocognitive assessments for living patients showed verbal episodic memory deterioration.
CONCLUSIONS
PCV-RT combination seems to have not only an oncological synergy but also a long-term neurotoxic synergy to consider before initial therapeutic decision.

Treatment of glioblastoma is challenging due to its aggressive and highly invasive nature, and no significant advances in survival have been achieved recently. The aim of our retrospective study was identification of predictive factors and consequent survival outcome in patients who underwent surgical and oncologic treatment of glioblastoma. The study was conducted at the Department of Neurosurgery, Osijek University Hospital Centre. The authors designed a retrospective cohort study in 63 patients who underwent surgical and oncologic treatment between January 1, 2012 and December 31, 2017. Data were collected by reviewing medical records of the patients with histologically proven glioblastoma. Statistical analysis of study results revealed a significant impact of postoperative radiotherapy (p=0.002) and chemotherapy (p=0.016) on progression-free survival and overall survival (p=0.001 and p=0.009, respectively). Postoperative Karnofsky performance scale (p=0.027) was found to be significant in progression-free survival, and so was the interval between surgery and commencement of oncologic therapy (p=0.049). In conclusion, overall survival and prognosis in the treatment of glioblastoma remain poor, although prompt approach in postoperative adjuvant treatments improved progression-free survival.

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.

Pulmonary fibrosis caused by bleomycin-induced pneumonia (BIP) is the most important side effect limiting the use of bleomycin and is mainly treated with corticosteroids. However, 1% to 4% of patients do not respond to corticosteroid therapy. Idiopathic pulmonary fibrosis and BIP develop by similar pathophysiological mechanisms. Nintedanib is a tyrosine kinase inhibitor used successfully in the treatment of idiopathic pulmonary fibrosis and there is no information about its use in BIP treatment. Here, we would like to present a 13-year-old boy with Hodgkin lymphoma who developed BIP after 2 cycles of ABVD (Adriamycin, bleomycin, vinblastine, and dacarbazine) and 4 cycles of BAECOPP (bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone), whose respiratory failure impaired despite corticosteroid therapy, but was successfully treated with nintedanib.

The incidence of haematological malignancies is increasing in women of childbearing age. Survival rates accompany this increase, making it essential to assess the impact of treatments on their future quality of life, evaluate the impact of each treatment on ovarian reserve and define the fertility preservation techniques used by women with haematologic malignancies. A retrospective study was conducted after data collection from 61 women diagnosed with haematological malignancies and followed-up in a fertility preservation centre between January 2008 and June 2019. Cancer treatments caused a decrease in ovarian reserve, demonstrated by an increase in FSH levels and a decrease in AMH levels. When assessing which treatments have the greatest impact on AMH levels, we found that the BEACOPP regimen, and the agents vincristine, etoposide, procarbazine, prednisone and the haematopoietic stem cell transplantation were mainly responsible. Regarding pregnancy after oncological treatments, of the eleven women who became pregnant, ten did so spontaneously. This study reinforces the importance of referring patients to a fertility preservation consultation before starting oncological treatment, as most of them opt to preserve fertility. This work also helps to clarify the impact of each chemotherapeutic agent on the ovarian reserve.

Primary central nervous system lymphoma(PCNSL)is an aggressive, extranodal non-Hodgkin lymphoma that arises from the central nervous system, eyes, leptomeninges, and the spinal cord. Most PCNSLs are a type of diffuse large B-cell lymphoma(DLBCL), and the majority are categorized as a non-germinal center B-cell(GCB)subtype. Recent genetic studies have revealed several common genetic abnormalities in PCNSL, such as and mutations, suggesting dependence on the B-cell receptor/Toll-like receptor signaling pathway. These genetic findings have rationalized targeted therapy targeting Bruton's tyrosine kinase(BTK), a key molecule of the B-cell receptor pathway in PCNSL and systemic non-GCB DLBCL. The first-generation BTK inhibitor ibrutinib has been widely studied in clinical trials for PCNSL and systemic non-GCB DLBCL. In Japan, a second-generation BTK inhibitor tirabrutinib was studied in a phase I/II trial and approved by the Japanese Ministry of Health and Welfare in March 2020 for relapsed and refractory PCNSL. While the current standard-of-care therapy for PCNSL is methotrexate(MTX)-based multi-agent induction immunochemotherapy like R-MPV(rituximab, MTX, procarbazine, and vincristine)followed by consolidation chemotherapy and/or radiation therapy, further investigation into the optimal use of BTK inhibitors in the standard-of-care therapy of PCNSL is warranted.

Nowadays, Hodgkin lymphoma (HL) has become highly curable. The young age at diagnosis and long life expectancy emphasize the importance of preventing long-term treatment side effects, including bone mineral density (BMD) loss, in these patients. We aimed to evaluate the effects of first-line therapeutic modalities on BMD dynamics in HL patients, intending to identify individuals at risk for osteopenia. Demographics, HL risk factors, treatment, including cumulative steroid doses, and BMD of 213 newly-diagnosed HL patients (median age 29 years), treated at Rambam between 2008-2016, were analyzed. The main chemotherapy regimens applied were: ABVD (adriamycin, bleomycin, vinblastine, dacarbazine) and escalated BEACOPP (EB; bleomycin, etoposide, adriamycin, cyclophosphamide, oncovin, procarbazine, prednisone). BMD was measured using PET/CT scans. BMD loss >15% was revealed in 48% of patients at therapy completion, with osteopenia prevalence of 4% and 14% at baseline and post-therapy, respectively. Cumulative hydrocortisone equivalent doses >3400 mg/m correlated with significant BMD reduction. Multivariate analysis at 6 months post-therapy identified age ≥30 years and EB-regimens as significant risk factors for BMD decrease >15%. Therapy-related BMD loss is common in HL patients. Its persistence is associated with age ≥30 years and EB treatment. Reduction of cumulative steroid doses and switch to non-gonadotoxic drugs should be considered.

OBJECTIVE
To provide a summary and analysis of the evidence for various agents applied as maintenance therapy and highlight ongoing trials or trials in development that evaluate the efficacy of maintenance therapy strategies in older patients with primary central nervous system lymphoma (PCNSL).
BACKGROUND
PCNSL are rare neoplasms that can have an aggressive course with short-lived remissions when compared to systemic diffuse large B-cell lymphoma (DLBCL). There is currently a paucity of evidence on treatment in older adults with PCNSL, who may be unfit to tolerate effective therapies for PCNSL. Those who can tolerate these therapies and survive PCNSL are at increased risk from developing treatment-related toxicity, functional decline, and debilitating neurotoxicity. While there is no clearly defined role for maintenance therapy after treatment of systemic DLBCL, it should be considered in PCNSL because central nervous system (CNS) recurrence often has a devastating and irreversible impact on neurologic function. Therefore, at least theoretically, use of effective maintenance therapy in older adults with PCNSL, either in lieu of consolidation or after consolidation therapy, may be better tolerated and help delay tumor progression, resulting in an improved overall global neurologic function and quality of life.
METHODS
We systematically searched MEDLINE (via PubMed) for all studies of drug treatments for maintenance therapy in PCNSL and also relied on expert opinion. We provide a summary and analysis of the evidence for various maintenance therapy agents, including methotrexate, rituximab, lenalidomide, temozolomide, ibrutinib, and procarbazine. We also highlight ongoing trials or trials in development that evaluate the efficacy of maintenance therapy in PCNSL.
CONCLUSIONS
Prospective clinical studies focusing on PCNSL patients who are not candidates for intensive post-induction therapy are scarce. To date, there are no studies that clarify whether maintenance therapy can be used in lieu of consolidation therapy with autologous stem cell transplant or radiation. Prospective studies may provide critical data regarding the identification of optimal agents, whether consolidation therapy could be replaced by maintenance therapy, and the overall role of maintenance therapy as a means to potentially improve survival and preserve quality of life and function in a vulnerable, older patient population.
