219 Background: The optimal dose for palliative whole brain radiotherapy (WBRT) continues to be debated. Common regimens include 20 Gy in five and 30 Gy in 10 fractions. We aimed to identify factors associated with WBRT dose schedules, hypothesizing that clinical prediction of survival (CPS) would influence prescribing practice. Methods: Demographic and clinicopathologic data were collected for consecutive patients with brain metastases receiving WBRT through a dedicated palliative radiation oncology clinic. At initial consultation, CPS were prospectively collected from treating radiation oncologists. Karnofsky performance status (KPS) and Mini-Mental Status Examination were available for 88.6% and 75.1%, respectively. Dose fractionation was collected and summary statistics calculated. Parameters were assessed for association with five fraction schedules using binary logistic regression, with odds ratios and 95% CI reported. Results: 193 patients underwent WBRT (N = 102 from 2010-2012; N = 91 from 2013-2014); 38/193 had 48 extracranial sites irradiated concurrently. 46.1% were male, mean age was 64.7 years (SD 11.6), and 63.7% had lung cancer. Median KPS was 70 (range 20-100) and median MMSE score was 27/30 (range 13-30). Median CPS and actual survival were 150 days (range 21-730d) and 96 days (range 11-1029d), respectively. 18.7% received WBRT within 30 days of death. 78.2% (151/193) and 17.6% (34/193) received five and 10 fractions, respectively; 8/193 were prescribed other schedules. On multivariate analysis, patients with KPS ≤ 70 were 5.93 times more likely to have received 5-fractions (95% CI 2.51-14.1; p < 0.0001). Those treated 2010-2012 were less likely to have received 5 fractions (OR 0.28; 95% CI 0.11-0.68; p = 0.005). CPS, age, gender, MMSE, histology, disease extent, and extracranial irradiation were not predictive of WBRT schedule. Conclusions: Patients treated with WBRT with KPS ≤70 and those treated more recently were more likely to receive five fractions. Oncologist CPS was not a statistically significant predictor of schedule in this cohort.

Abstract Backgrounds: Standard care for primary central nervous system lymphoma (PCNSL) comprises high-dose (HD) methotrexate (MTX) -based chemotherapy with or without consolidation whole brain radiotherapy (WBRT). HD-MTX administration following WBRT has been suggested to increase a risk of leukoencephalopathy. However, given that there are no other agents with efficacy similar to or better than MTX, patients with relapsed PCNSL may often be treated with regimens containing HD-MTX if the initial MTX treatment achieved a long-term complete remission. Here, we retrospectively analyzed prevalence and an extent of white mater damages in association with prior WBRT in patients with relapsed PCNSL treated with HD-MTX based therapy. Patients & methods: Among 79 patients with relapsed/refractory PCNSL in a total of 162 patients with newly-diagnosed PCNSL treated in our institution from April, 2000 to February, 2021, 35 patients were identified with evaluable KPS, MMSE, and Fazekas scale data at both baseline and follow-up periods. Of the 35 patients, 22 were treated with chemotherapy at a relapse (10 with prior WBRT, while 12 without WBRT), and were included in this preliminary study. Results: In the WBRT group (male/female: 5/5), median age was 65 years (range, 45–73), initial median KPS was 70 (40–90), and median WBRT dose was 27 Gy (23.4–40). Median progression-free survival (mPFS) was 11.8 months, and median overall survival (mOS) was not reached. In the non-WBRT group (M/F 8/4), median age 75 (62–84), initial mKPS 80 (50–90), mPFS 16.2 m, and mOS not reached. Initial KPS and MMSE score tended to be worse in WBRT group, presumably due to enrichment of patients with poorer performance status and more comorbidities. A decline in the Fazekas score was not associated with MMSE deterioration.Conclusions: The preliminary analysis was not informative enough, and further extensive imaging analysis will be exploited.

AbstractWith the improvements in systemic treatment for lung cancer, distant metastasis to sanctuary sites such as brain has become an increasingly more important issue. The management of these patients consists of supportive care and disease-directed treatment. Combined modality treatment (surgical resection or radiosurgery, followed by whole brain radiotherapy) of brain metastases has greatly improved the local control of disease in patients with single lesion, good functional performance status, and controlled extracranial disease as demonstrated in prospective randomized studies. For patients with multiple brain metastases, conventional fractionated whole brain radiotherapy continues to be a standard and efficacious treatment. At present, experience with the use of molecularly targeted tyrosine kinase inhibitors in nonsmall cell lung cancer patients with activating mutations in the epidermal growth factor receptor gene and anaplastic lymphoma kinase gene is growing. However, their effectiveness in patients with brain metastases is not well established. In the arena of targeted therapies, vascular endothelial growth factor pathway inhibitors such as bevacizumab have shown some activity in brain metastases. Further prospective studies are necessary to facilitate selection of patient subpopulation for targeted agents in future studies.

Impaired heart rate variability (HRV) has been demonstrated as a negative survival prognosticator in various diseases. We conducted this prospective study to evaluate how HRV affects brain metastasis (BM) patients. Fifty-one BM patients who had not undergone previous brain operation or radiotherapy (RT) were recruited from January 2010 to July 2012, and 40 patients were included in the final analysis. A 5-minute electrocardiogram was obtained before whole brain radiotherapy. Time domain indices of HRV were compared with other clinical factors on overall survival (OS). In the univariate analysis, Karnofsky performance status (KPS) <70 (P=0.002) and standard deviation of the normal-to-normal interval (SDNN) <10 ms (P=0.004) significantly predict poor survival. The multivariate analysis revealed that KPS <70 and SDNN <10 ms were independent negative prognosticators for survival in BM patients with hazard ratios of 2.657 and 2.204, respectively. In conclusion, HRV is associated with survival and may be a novel prognostic factor for BM patients.

32 Background: Radiosurgery (SRS) is a standard palliative treatment for patients with limited number of brain metastases. Growing evidence supports the use of SRS for more extensive disease. As SRS is increasingly used in advanced cancer, we sought to identify predictors of survival after SRS to help better inform patients about prognosis. Methods: We reviewed patients treated with SRS for brain metastases at the University of California, San Francisco (UCSF) from Jan 2010-Dec 2013. Before SRS, all patients were screened for appropriateness of SRS at a multidisciplinary conference. Post-SRS overall survival (OS) was estimated by Kaplan-Meier method and compared by log-rank tests. Frequencies of death within 30 days of SRS were compared by chi-squared tests. Results: Demographic and imaging data was available for 326 SRS patients. At SRS consult, 90% patients were Karnofsky Performance Status (KPS) ≥ 70. Median number of brain metastases at consult was 2 (range 1-37). Median follow up was 13 months. Median OS after SRS was 11 months. Median OS was shorter for patients with KPS < 70 (4 months) compared to those with KPS ≥ 70 (12 months) (p < 0.001). Overall, frequency of death within 30 days of SRS was 5.4%. Within 30 days of SRS, 13% of patients with KPS < 70 died compared to 3.8% with KPS ≥ 70 (p = 0.03). Death within 30 days of SRS was more common among patients with uncontrolled (10%) versus controlled primary tumors (3%) (p = 0.02). Both uncontrolled primary tumor and KPS < 70% were associated with death within 30 days of SRS on multivariate analysis (p = 0.02 and p = 0.03, respectively). Patients with both KPS < 70 and uncontrolled primary tumors had frequency of death within 30 days of 29%. Factors not associated with death within 30 days were age, extracranial metastatic disease burden, histology, number of brain metastases, prior whole brain radiotherapy, SRS, or neurosurgery. Conclusions: Death within 30 days of SRS within the UCSF cohort is uncommon, likely due to multidisciplinary screening for patients expected to live long enough to benefit from SRS. Most patients who die within 30 days of SRS have both KPS < 70 and uncontrolled primary tumors. The potential for poor prognosis should be discussed with these patients during shared-decision making.

Abstract Objective The optimal regimen for use of high dose-methotrexate-based chemotherapy in primary central nervous system lymphoma is still under debate. We conducted a retrospective study to evaluate the treatment outcome of a combination immunochemotherapy consisting of rituximab, methotrexate, procarbazine and vincristine followed by with or without whole brain radiotherapy and consolidation cytarabine, in comparison with high dose-methotrexate monotherapy followed by full dose whole brain radiotherapy. Methods Newly diagnosed primary central nervous system lymphoma patients treated with either rituximab, methotrexate, procarbazine and vincristine or high dose-methotrexate in Kyorin University Hospital were identified, and the response rates and survival were compared. Toxicities, post-treatment transition of Mini-Mental State Examination, Karnofsky performance status score, Fazekas scale and prognostic factors were analysed in the rituximab, methotrexate, procarbazine and vincristine group. Results Ninety-five patients treated with rituximab, methotrexate, procarbazine and vincristine (n = 39) or high dose-methotrexate (n = 56) were analysed. The complete response/complete response unconfirmed rate was significantly higher in the rituximab, methotrexate, procarbazine and vincristine group (74.4 vs. 15.4%, P &lt; 0.001). Accordingly, both median progression-free survival and overall survival were significantly longer in the rituximab, methotrexate, procarbazine and vincristine group (median progression-free survival: unreached vs. 14.75 months, P &lt; 0.001) (median overall survival: unreached vs. 63.15 months, P = 0.005). Although the rate of grade 3/4 hematologic toxicities was high both during rituximab, methotrexate, procarbazine and vincristine and consolidation cytarabine, the rate of grade 3/4 infections was low, and no treatment related deaths were observed. Deterioration in Karnofsky performance status or Mini-Mental State Examination was rare, except on disease recurrence. Although whole brain radiotherapy was associated with Fazekas scale deterioration, its association with Karnofsky performance status or Mini-Mental State Examination deterioration was not significant. Conclusions Rituximab, methotrexate, procarbazine and vincristine was apparently promising in comparison with high dose-methotrexate monotherapy with manageable toxicity in this retrospective study, and further investigation is warranted.

Brain Radiotherapy

The overall local treatment paradigm of brain metastases, which includes whole-brain radiotherapy (WBRT) and stereotactic radiosurgery (SRS), continues to evolve. Local therapies play an important role in the management of brain metastases. The choice of local therapy depends on factors that involve the patient (performance status, expected survival, and age), the prior treatment history, and the tumor (type and subtype, number, size, location of metastases, and extracranial disease status). Multidisciplinary collaboration is required to facilitate an individualized plan to improve the outcome of disease in patients with this life-limiting complication. There has been concern about the neurocognitive effects of WBRT. A number of approaches that mitigate cognitive dysfunction, such as pharmacologic intervention (memantine) or a hippocampal-sparing strategy, have been studied in a prospective manner with WBRT. Although there has been an increase in the use of SRS in the management of brain metastases in recent years, WBRT retains an important therapeutic role.

Purpose This European Organisation for Research and Treatment of Cancer phase III trial assesses whether adjuvant whole-brain radiotherapy (WBRT) increases the duration of functional independence after surgery or radiosurgery of brain metastases. Patients and Methods Patients with one to three brain metastases of solid tumors (small-cell lung cancer excluded) with stable systemic disease or asymptomatic primary tumors and WHO performance status (PS) of 0 to 2 were treated with complete surgery or radiosurgery and randomly assigned to adjuvant WBRT (30 Gy in 10 fractions) or observation (OBS). The primary end point was time to WHO PS deterioration to more than 2. Results Of 359 patients, 199 underwent radiosurgery, and 160 underwent surgery. In the radiosurgery group, 100 patients were allocated to OBS, and 99 were allocated to WBRT. After surgery, 79 patients were allocated to OBS, and 81 were allocated to adjuvant WBRT. The median time to WHO PS more than 2 was 10.0 months (95% CI, 8.1 to 11.7 months) after OBS and 9.5 months (95% CI, 7.8 to 11.9 months) after WBRT (P = .71). Overall survival was similar in the WBRT and OBS arms (median, 10.9 v 10.7 months, respectively; P = .89). WBRT reduced the 2-year relapse rate both at initial sites (surgery: 59% to 27%, P < .001; radiosurgery: 31% to 19%, P = .040) and at new sites (surgery: 42% to 23%, P = .008; radiosurgery: 48% to 33%, P = .023). Salvage therapies were used more frequently after OBS than after WBRT. Intracranial progression caused death in 78 (44%) of 179 patients in the OBS arm and in 50 (28%) of 180 patients in the WBRT arm. Conclusion After radiosurgery or surgery of a limited number of brain metastases, adjuvant WBRT reduces intracranial relapses and neurologic deaths but fails to improve the duration of functional independence and overall survival.
