Abstract BACKGROUND Current treatment guidelines for oligodendrogliomas (OD) recommend watch-and-wait strategies after gross total resection and radiation with subsequent chemotherapy (procarbazine, CCNU and vincristine (PCV)) after incomplete resection. The value of chemotherapy alone as an option to delay the risk of late cognitive deficits is not well defined yet. Here, we retrospectively investigated long-term outcome in OD WHO II with respect to initial therapy and tumor volume in magnetic resonance imaging (MRI). METHODS A total of 142 patients with OD WHO (World Health Organization) II according to WHO 2016 were retrospectively included. Patients either had watch and wait (W&W) after histological sampling through stereotactic biopsy (n=59) or tumor resection (n=27) or else stereotactic biopsy with subsequent temozolomide (TMZ) (n=26) or PCV (n=30). Pre- and post-therapeutic T2 tumor volumes were obtained. Progression-free survival (PFS), post-recurrence PFS (PR-PFS) and rate of secondary malignization after 10 years (MR-10yrs) were correlated with clinical and volumetric data. RESULTS PFS was significantly longer in the PCV cohort compared to TMZ (9.1 vs. 3.6 years, p = 0.04), even after matching patients according to age and initial tumor volume (9.1 vs 4.7 yrs, p = 0.03). PFS in the W&W cohort was 5.1 years and 4.4 years in those receiving tumor resection only. MR-10yrs was 4% in PCV cohort, 18% in the W&W cohort and 52% in the resection only cohort (p = 0.01). In the W&W cohort, patients treated with PCV at first relapse had a longer PR-PFS than those treated with TMZ (in years, 7.2 vs 4.0, p = 0.04). Multivariate analysis confirmed initial PCV therapy (p = 0.01) and initial T2 tumor volume (p = 0.02) to be prognostic. CONCLUSION In oligodendrogliomas WHO II PCV chemotherapy alone is superior in terms of PFS and rate of secondary malignization compared to TMZ chemotherapy alone or tumor resection only.

Abstract Introduction The role of chemotherapy alone in newly diagnosed WHO grade 2 oligodendroglioma after biopsy, incomplete or gross total resection remains controversial. We here analyze the clinical outcome of four patient cohorts being treated with either procarbazine, CCNU and vincristine (PCV) or temozolomide (TMZ) after biopsy, resection only, or wait-and-scan after biopsy. Methods Patients (n = 142) with molecularly defined oligodendroglioma (WHO 2016) were assigned to four cohorts: W&S, wait-and-scan after stereotactic biopsy (n = 59); RES, surgical resection only (n = 27); TMZ, temozolomide after biopsy (n = 26) or PCV (n = 30) after biopsy. Presurgical MRI T2 tumor volumes were obtained by manual segmentation. Progression-free survival (PFS), post-recurrence PFS (PR-PFS) and rate of histological progression to grade 3 were analyzed. Results PFS was longest after PCV (9.1 years), compared to 5.1 years after W&S, 4.4 years after RES and 3.6 years after TMZ. The rate of histological progression from grade 2 to 3 within 10 years was 9% for the PCV, 29% for the W&S, 67% for the RES and 75% for the TMZ group (p = 0.01). In the W&S group, patients treated with PCV at first relapse had a longer PFS from intervention than those treated with TMZ (7.2 vs 4.0 years, p = 0.04). Multivariate analysis identified smaller tumor volume prior to any intervention (p = 0.02) to be prognostic for PFS. Conclusions PCV chemotherapy alone is an effective treatment for WHO grade 2 oligodendroglioma, with long PFS and low rate of histological progression.

Abstract Background The optimal chemotherapy regimen between temozolomide and procarbazine, lomustine, and vincristine (PCV) remains uncertain for W.H.O. grade 3 oligodendroglioma (Olig3) patients. We therefore investigated this question using national data. Methods Patients diagnosed with radiotherapy-treated 1p/19q-codeleted Olig3 between 2010-2018 were identified from the National Cancer Database. The OS associated with first-line single-agent temozolomide vs. multi-agent PCV was estimated by Kaplan-Meier techniques and evaluated by multivariable Cox regression. Results 1,596 radiotherapy-treated 1p/19q-codeleted Olig3 patients were identified: 88.6% (n=1,414) treated with temozolomide and 11.4% (n=182) with PCV (from 5.4% in 2010 to 12.0% in 2018) in the first-line setting. The median follow-up was 35.5 months (interquartile range [IQR] 20.7-60.6 months) with 63.3% of patients alive at time of analysis. There was a significant difference in unadjusted OS between temozolomide (5yr-OS 58.9%, 95%CI: 55.6-62.0) and PCV (5yr-OS 65.1%, 95%CI: 54.8-73.5; p=0.04). However, a significant OS difference between temozolomide and PCV was not observed in the Cox regression analysis adjusted by age and extent of resection (PCV vs. temozolomide HR 0.81, 95%CI: 0.59-1.11, p=0.18). PCV was more frequently used for younger Olig3s, but otherwise was not associated with patient’s insurance status or care setting. Conclusions In a national analysis of Olig3s, first-line PCV chemotherapy was associated with a slightly improved unadjusted short-term OS compared to temozolomide; but not following adjustment by patient age and extent of resection. There has been an increase in PCV utilization since 2010. These findings provide preliminary data while we await the definitive results from the CODEL trial.

AbstractPURPOSEThe optimal chemotherapy regimen between temozolomide (TMZ) and procarbazine, lomustine, and vincristine (PCV) remains uncertain for newly-diagnosed anaplastic oligodendroglioma (AO). We therefore addressed this question using a national database.METHODSPatients newly-diagnosed with 1p/19q-codeleted W.H.O. grade III AO between 2010-2016 were identified from the National Cancer Database. Predictors of receiving first-line single-agent TMZ vs. multi-agent PCV were assessed by multivariable logistic regression. Overall survival (OS) was estimated by Kaplan-Meier techniques and evaluated by multivariable Cox regression.RESULTS1,360 AO patients were identified: 74.5% (n=1,013) treated with TMZ, 9.6% (n=131) with PCV, and 15.9% (n=216) with no chemotherapy in the first-line setting. In multivariable logistic analysis, PCV utilization increased from 2010 to 2016 (OR=1.38/year, 95%CI: 1.22-1.56, p<0.001) and was less commonly utilized in privately insured patients (OR=0.38 vs. uninsured, 95%CI: 0.15-0.97, p=0.04). In survival analyses (33.1% reached endpoint), there was no difference in unadjusted OS between TMZ (5yr-OS 60.1%, 95%CI: 55.9-64.1) and PCV (5yr-OS 61.1%, 95%CI: 45.6-73.5; p=0.42). There remained no OS difference between TMZ and PCV in the 75.9% (n=1,032) of AO patients that also received radiotherapy (p=0.51), in the Cox regression analysis adjusted by age, extent of resection, and radiotherapy (TMZ vs. PCV HR=1.31, 95%CI: 0.83-2.08, p=0.24), and in subgroup analyses that incorporate KPS or MGMT status.CONCLUSIONSIn a national database of AOs managed in the ‘real-world’ setting, there is no difference in the short-term mortality between first-line TMZ and PCV chemotherapy. These findings provide preliminary data while we await the long-term results from the CODEL trial.

Purpose Little is known about the health-related quality of life (HRQOL) of patients treated for anaplastic oligodendrogliomas. The impact of combined procarbazine, CCNU (lomustine), and vincristine (PCV) chemotherapy after radiotherapy (RT) compared with RT alone on HRQOL in the randomized European Organisation for Research and Treatment of Cancer (EORTC) 26951 trial was studied. Patients and Methods Adult patients with anaplastic oligodendrogliomas received RT alone or RT plus PCV chemotherapy. HRQOL was assessed with the EORTC Quality of Life Questionnaire C30 and Brain Cancer Module. Seven prespecified HRQOL end points were selected. We hypothesized that chemotherapy would impair HRQOL during treatment but that there would be a similar HRQOL between treatment arms once off treatment. Assessments were performed at randomization, at the end of RT, and then every 3 to 6 months until progression. Results A total of 368 patients were randomly assigned to one of the two arms; overall, 58% were male, and the median age was 49 years. Compliance with HRQOL was 78% at baseline and dropped to 55% to 72% up to 2.5 years post-RT. Baseline scores demonstrated considerable impairments in HRQOL for both treatment groups. The longitudinal analysis showed a significant increase in nausea/vomiting in the RT plus PCV chemotherapy arm during and shortly after chemotherapy. Because of a difference in baseline scores for fatigue and physical functioning, the differences between treatment arms during PCV did not reach significance. The nonselected scales of appetite loss and drowsiness demonstrated significant differences between treatment arms during chemotherapy in favor of the RT arm. The long-term results showed no difference between arms. Conclusion The major impact of PCV on HRQOL is on nausea/vomiting, loss of appetite, and drowsiness during and shortly after treatment. There are no long-term effects of PCV chemotherapy.
