Review
Gliomas classified as grade II by the World Health Organization (WHO) include astrocytomas, oligodendrogliomas, and mixed oligoastrocytomas. This heterogeneous group of conditions is associated with a more favorable prognosis and longer-term survival than high-grade gliomas (HGGs). Neurosurgical resection and radiation therapy improve survival in symptomatic, progressive, or high-risk grade II gliomas. Until recently, the role of chemotherapy has been less clear. This review draws on insights from the management of HGGs and emerging data on the addition of PCV (procarbazine, lomustine [CCNU], and vincristine) to radiation for these neoplasms. Specifically, this review focuses on the current status of chemotherapeutic management of grade II gliomas, including optimal timing of treatment, and management of 1p19q codeleted and non-codeleted tumors.

Review
Elderly Hodgkin lymphoma (HL), commonly defined as occuring in patients over 60 to 65 years of age, is an uncommon disease. In population-based studies, the proportion of HL patients over age 60 years has rangedfrom 15% to 30%. However, the proportion of patients over age 60 years in clinical trials has been considerably lower, typically constituting < 5% to 10% of participants. Elderly HL patients commonly present with mixed cellularity histology, B symptoms, advanced stage, and Epstein-Barr virus-positive disease. Progression-free and overall survival rates for elderly HL patients are disproportionately inferior to those of younger patients. Generally, treatment of elderly HL for all disease stages should be given with curative intent, but more effective, tolerable therapeutic regimens are needed. No standard treatment recommendations exist for elderly HL Bleomycin-containing regimens including ABVD (doxorubicin [Adriamycin], bleomycin, vinblastine, dacarbazine) are associated with pulmonary toxicity, and intensive therapy such as BEACOPP (bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine [Oncovin], procarbazine [Matulane], prednisone) is poorly tolerated, whereas less-intensive regimens such as CVP/CEB (chlorambucil [Leukeran], vinblastine, procarbazine, prednisone, cyclophosphamide, etoposide, bleomycin) and ChlVPP (chlorambucil, vinblastine, procarbazine, prednisolone) appear to be less effective than anthracycline-based regimens. Recent data using CHOP (cyclophosphamide, doxorubicin, vincristine, prednisone) in this population merit further investigation. In addition, further evaluation of the prognostic value of early PET in elderly HL is warranted. Continued multicenter collaborations with prospective clinical trials, including formal assessment of comorbidity and functional status, will be critical to the successful study of elderly HL.

Canine gastrointestinal (GI) and hepatosplenic (HS) high-grade (large cell) lymphomas are uncommon forms of canine lymphomas, with a very poor response to chemotherapy and a very poor prognosis. Currently, there are no established effective chemotherapy protocols for canine GI/HS lymphomas. This case series aimed to retrospectively evaluate the efficacy of lomustine-based protocols L-LOP (L-asparaginase, lomustine, vincristine, and prednisolone) and L-LOPP (with the addition of procarbazine) for treatment of canine GI/HS lymphomas. Medical records of dogs with cytologically or histologically diagnosed lymphoma at CityU Veterinary Medical Centre from 2019 to 2022 were retrospectively reviewed. The L-LOP/LOPP treatment protocol was well tolerated with rare severe adverse events. Median progression-free survival for GI and HS lymphoma was 56 days (range, 10-274 days) and 57 days (range 8-135 days) respectively; while median survival time for GI and HS lymphoma was 93 days (range 10-325 days) and 210 days (range 8-240 days) respectively.

Review
Treatment of blood malignancies and other cancer diseases has been mostly unfeasible, so far. Therefore, novel treatment regimens should be developed and the currently used ones should be further elaborated. A stable component in various cancer treatment regimens consists of vincristine, an antimitotic compound of natural origin. Despite its strong anticancer activity, mostly, it cannot be administered as monotherapy due to its unspecific action and severe side effects. However, vincristine is suitable for combination therapy. Multidrug treatment regimens including vincristine are standardly applied in the therapy of non-Hodgkin lymphoma and other malignancies, in which it is combined with drugs of different mechanisms of action, mainly with DNA-interacting compounds (for example cyclophosphamide), or drugs interfering with DNA synthesis (for example methotrexate). Besides, co-administration of vincristine with monoclonal antibodies has also emerged, the typical example of which is the anti-CD20 antibody rituximab. Although in some combination anticancer therapies, vincristine has been replaced with other drugs exhibiting lesser side effects, though, in most cases, it is still irreplaceable. This is strongly evidenced by the number of active clinical trials evaluating vincristine in combination cancer therapy. Therefore, in this article, we have reviewed the most common cancer treatment regimens employing vincristine and bring an overview of current trends in the clinical development of this compound.

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%.

Randomized Controlled Trial
PURPOSE
The AHL2011 study (ClinicalTrials.gov identifier: NCT01358747) demonstrated that a positron emission tomography (PET)-driven de-escalation strategy after two cycles of bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone (BEACOPP) provides similar progression-free survival (PFS) and overall survival (OS) and reduces early toxicity compared with a nonmonitored standard treatment. Here, we report, with a prolonged follow-up, the final study results.
METHODS
Patients with advanced Hodgkin lymphoma (stage III, IV, or IIB with mediastinum/thorax ratio > 0.33 or extranodal involvement) age 16-60 years were prospectively randomly assigned between 6 × BEACOPP and a PET-driven arm after 2 × BEACOPP delivering 4 × ABVD (doxorubicin, bleomycin, vinblastine, and dacarbazine) in PET2- and 4 × BEACOPP in PET2+ patients. PET performed after four cycles of chemotherapy had to be negative to complete the planned treatment.
RESULTS
In total, 823 patients were enrolled including 413 in the standard arm and 410 in the PET-driven arm. With a 67.2-month median follow-up, 5-year PFS (87.5% 86.7%; hazard ratio [HR] = 1.07; 95% CI, 0.74 to 1.57; = .67) and OS (97.7% in both arms; HR = 1.012; 95% CI, 0.50 to 2.10; = .53) were similar in both randomization arms. In the whole cohort, full interim PET assessment predicted patients' 5-year PFS (92.3% in PET2-/PET4-, 75.4% [HR = 3.26; 95% CI, 18.3 to 5.77] in PET2+/PET4- and 46.5% [HR = 12.4; 95% CI, 7.31 to 19.51] in PET4+ patients, respectively; < .0001) independent of international prognosis score. Five-year OS was also affected by interim PET results, and PET2+/PET4- patients (93.5%; HR = 3.3; 95% CI, 1.07 to 10.1; = .036) and PET4+ patients (91.9%; HR = 3.756; 95% CI, 1.07 to 13.18; = .038) had a significant lower OS than PET2-/PET4- patients (98.2%). Twenty-two patients (2.7%) developed a second primary malignancy, 13 (3.2%) and 9 (2.2%) in the standard and experimental arms, respectively.
CONCLUSION
The extended follow-up confirms the continued efficacy and favorable safety of AHL2011 PET-driven strategy, which is noninferior to standard six cycles of BEACOPP. PET4 provides additional prognostic information to PET2 and allows identifying patients with particularly poor prognosis.

Clinical Trial Comparative Study Randomized Controlled Trial Review
Initial results from studies with third-generation combination chemotherapy regimens for the treatment of aggressive non-Hodgkin's lymphomas (NHL) demonstrated complete remission (CR) rates higher than those reported with first-generation regimens. Long-term follow-up of these studies is required to know if the increased number of CRs translates into an increased number of long-term disease-free survivors. In this report, results obtained with one of the third-generation regimens, ProMACE (prednisone/methotrexate/doxorubicin/cyclophosphamide/etoposide)-Cyta BOM (cytarabine/bleomycin/vincristine/methotrexate) are described. From 1981 to 1988, 193 patients with stage II, III, or IV aggressive NHL treated at the National Cancer Institute were randomly assigned to receive either ProMACE (day 1)-CytaBOM (day 8) or ProMACE (day 1)-MOPP (mechlorethamine/vincristine/procarbazine/prednisone) (day 8). With a median follow-up of 5 years, the CR rate was 86% for ProMACE-CytaBOM v 74% for ProMACE-MOPP (P = 0.048). A plateau in the disease-free survival curve is seen at 69% for ProMACE-CytaBOM v 54% for ProMACE-MOPP (P = 0.082). A plateau is also seen in the overall survival curves at 69% for ProMACE-CytaBOM v 53% for ProMACE-MOPP (P = 0.046). The Southwest Oncology Group also conducted a phase II study of ProMACE-CytaBOM in 78 patients with stages II to IV intermediate- or high-grade NHL to determine the CR rate and long-term disease-free survival of this regimen in a national cooperative group setting. The CR rate was 65%. With a median follow-up of 38 months, disease-free survival is 50% at 3 years and overall survival is 57% at the same time point.(ABSTRACT TRUNCATED AT 250 WORDS)

Comparative Study Review
World Health Organization grade II gliomas (GIIGs) include diffuse astrocytoma, oligodendroglioma, and oligoastrocytoma. GIIG is a malignant brain tumor for which the treatment outcome can still be improved. Review of previous clinical trials found the following: (1) GIIG increased in size by 3-5 mm per year when observed or treated with surgery alone; (2) after pathological diagnosis, the survival rate was increased by early aggressive tumor removal at an earlier stage compared to observation alone; (3) although the prognosis after total tumor removal was significantly better than that after partial tumor removal, half of the patients relapsed within 5 years; (4) comparing postoperative early radiotherapy (RT) and non-early RT after relapse, early RT prolonged progression-free survival (PFS) but did not affect overall survival (OS); (5) local RT of 45 to 64.8 Gy did not impact PFS or OS; (6) in patients with residual tumors, RT combined with chemotherapy (procarbazine plus lomustine plus vincristine) prolonged PFS compared with RT alone but did not affect OS; and (7) poor prognostic factors included astrocytoma, non-total tumor removal, age ≥40 years, largest tumor diameter ≥4-6 cm, tumor crossing the midline, and neurological deficit. To improve treatment outcomes, surgery with functional brain mapping or intraoperative magnetic resonance imaging or chemoradiotherapy with temozolomide is important. In this review, current knowledge regarding GIIG is described and treatment strategies are explored.

Review
Seizures represent a common symptom in low-grade gliomas; when uncontrolled, they significantly contribute to patient morbidity and negatively impact quality of life. Tumor location and histology influence the risk for epilepsy. The pathogenesis of tumor-related epilepsy is multifactorial and may differ among tumor histologies (glioneuronal tumors vs diffuse grade II gliomas). Gross total resection is the strongest predictor of seizure freedom in addition to clinical factors, such as preoperative seizure duration, type, and control with antiepileptic drugs (AEDs). Epilepsy surgery may improve seizure control. Radiotherapy and chemotherapy with alkylating agents (procarbazine + CCNU+ vincristine, temozolomide) are effective in reducing the frequency of seizures in patients with pharmacoresistant epilepsy. Newer AEDs (levetiracetam, topiramate, lacosamide) seem to be better tolerated than the old AEDs (phenobarbital, phenytoin, carbamazepine), but there is lack of evidence regarding their superiority in terms of efficacy.

Radiotherapy Plus Procarbazine, Lomustine, and Vincristine Versus Radiotherapy Plus Temozolomide for IDH-Mutant Anaplastic Astrocytoma: A Retrospective Multicenter Analysis of the French POLA Cohort.
BACKGROUND
IDH-mutant anaplastic astrocytomas (AAs) are chemosensitive tumors for which the best choice of adjuvant chemotherapy between procarbazine, lomustine, and vincristine (PCV) or temozolomide (TMZ) after radiotherapy (RT) remains unclear.
METHODS
In a large cohort of patients with histologically proven 2016 World Health Organization classification AA with IDH1/2 mutations included in the French national POLA cohort (n = 355), the primary objective was to compare progression-free survival (PFS) between the two treatment regimens (n = 311). Secondary endpoints were overall survival (OS), progression type, pseudoprogression rate, and toxicity.
RESULTS
The 4-year PFS in the RT + PCV arm was 70.8% versus 53.5% in the RT + TMZ arm, with a hazard ratio (HR) of 0.58 (95% confidence interval [CI], 0.38-0.87; p = .0074) in univariable analysis and 0.63 (95% CI, 0.41-0.97; p = .0348) in multivariable analysis. The 4-year OS in the RT + PCV arm was 84.3% versus 76.6% in the RT + TMZ arm, with an HR of 0.57 (95% CI, 0.30-1.05; p = .0675) in univariable analysis. Toxicity was significantly higher in the RT + PCV arm with more grade ≥3 toxicity (46.7% vs. 8.6%, p < .0001).
CONCLUSION
RT + PCV significantly improved PFS compared with RT + TMZ for IDH-mutant AA. However, RT + TMZ was better tolerated.
IMPLICATIONS FOR PRACTICE
In the absence of fully conducted randomized trials comparing procarbazine, lomustine, and vincristine (PCV) with temozolomide (TMZ) in adjuvant treatment after radiotherapy (RT) for the management of IDH-mutant anaplastic astrocytoma (AA) and a similar level of evidence, these two chemotherapies are both equally recommended in international guidelines. This study in a national cohort of IDH-mutant AA defined according the 2016 World Health Organization (WHO) classification shows for the first time that the RT + PCV regimen significantly improves progression-free survival in comparison with the RT + TMZ regimen. Even if at the time of analysis the difference in overall survival was not significant, this result provides new evidence for the debate about the chemotherapy regimen to prescribe in adjuvant treatment to RT for WHO 2016 IDH-mutant AA.
