Abstract BACKGROUND The prognosis for brain metastasis is poor, and surgical resection is part of the standard of care for these patients as it has been shown to improve median overall survival. Development of neurological deficits after surgical resection has been associated with worsened outcomes in patients with glioblastoma. The effect of postoperative neurological deficits on survival in patients with single brain metastasis has not been studied to date. OBJECTIVE To evaluate the association between postoperative neurological deficits and median overall survival. METHODS A single-institution retrospective cohort study was performed on all patients with single brain metastasis undergoing surgical resection by a single neurosurgeon. RESULTS A total of 121 patients met the inclusion criteria for this study. Among them 61% of patients presented with a preoperative deficit, and 26% of patients had a new postoperative deficit. However, most postoperative deficits resolved and only 3.3% of patients developed a new permanent postoperative deficit. Median overall survival in patients with a new postoperative deficit was 2.4 mo, whereas mOS in patients without a postoperative deficit was 12.6 mo (P < .0001). CONCLUSION This study suggests that a new neurological deficit is associated with worsened outcomes after surgical resection of a single brain metastasis. This finding has potential implications for patient selection and counseling as the patients most likely to benefit from surgical resection are the patients who are most likely to have resolution of a preoperative deficit.

ObjectiveThe reported incidence of brain metastasis from epithelial ovarian cancer (EOC), endometrial cancer (EC), and cervical cancer (CC) is exceedingly rare. As the long-term survival for patients with gynecologic cancer increases, there has been a corresponding increase in the number of diagnosed intracranial metastases. We seek to report our experience with managing brain metastatic disease (BMD) in patients with gynecologic cancer.MethodsA retrospective review of all patients with EOC, EC, and CC at our institution revealed 47 patients with concurrent BMD between 2000 and 2013. Demographic data, risk factors, treatment modalities, progression-free data, and overall survival data were collected.ResultsMedian survival time in patients with brain metastasis from EOC, EC, and CC was 9.0, 4.5, and 3.0 months, respectively. Two-year overall survival rates were 31.6%, 13.6%, and 0%, respectively. Patients received surgery, radiation therapy alone, palliative care, or radiation plus surgery. Radiation combined with surgical resection resulted in a significant hazards ratio of 0.36 (95% confidence interval, 0.15–0.86), compared with radiation alone.ConclusionsOur report provides a large single-institution experience of brain metastases from gynecologic cancer. Patients with BMD have poor prognoses; however, treatment with multimodal therapy including surgical resection and radiation may prolong overall survival.

e11569 Background: Resection of a single brain metastasis (SBM) in metastatic cancer has been shown to improve overall survival (OS). A previously reported series from MD Anderson of breast cancer patients undergoing SBM resection reported a median overall survival of 19 months. We report our experience of SBM resection for breast cancer. Methods: Retrospective observational study of patients who underwent resection of SBM from breast cancer brain in a tertiary referral centre from 2000-2011. Results: 20 patients underwent SBM resection from 2000-2011. All patients received WBRT after surgery. 2 patients had progressive metastatic disease presenting as brain metastases. Median time from original breast cancer diagnosis to development of SBM was 53 months (range:1-286months). 9 patients had solitary brain metastases (no metastases elsewhere) and 11 patients had synchronous metastases elsewhere. Regarding the primary breast tumour: 41% of patients were ER+, 57% were HER2+ and 25% were triple negative. 1 patient had discordance of ER status between the primary tumour and brain metastasis (changed from ER- to ER+). Median overall survival was 9 months (95% CI: 5-18 months) with 1 year OS of 50%, 2 year OS of 15% and 3 year OS of 5%. Patients treated between 2006-2011 had better median OS than those treated 2000-2005(18 months vs 6 months – p-value not significant). Patients with a solitary brain metastasis had better median OS than those with synchronous extracranial disease (13 months vs 6 months – p-value not significant). An additional 2 patients underwent craniotomy for presumed breast cancer metastasis but histology revealed glioblastoma multiforme. Conclusions: We report on a cohort of patients undergoing metastatectomy for single brain metastasis from breast cancer. Median OS was 9 months but there was a trend towards better survival in patients treated in recent years when compared with those treated from 2000-2005. Improved systemic therapies may account for this difference. Also of note 2 patients undergoing resection for presumed brain metastases were found to have GBM, highlighting the role of tissue diagnosis in patients presenting with a solitary brain lesion.

Activating Mutations

e14501 Background: Patients with resected pancreas cancer treated with standard of care Gem have a median overall survival of 22 months (vs 20 months w/ observation). Activating mutations in ras occur in > 90% of pancreas cancer cases. GI-4000 is whole, heat-killed recombinant S. cerevisiae yeast that expresses mutated Ras proteins. This trial is designed to evaluate the efficacy, immunogenicity, and safety of GI-4000 plus Gem in patients with Ras mutant + resected pancreas cancer. Methods: The study enrolled 176 Ras mutant + pancreas cancer subjects post resection randomized 1:1 to GI-4000 plus Gem or placebo plus Gem (stratified by resection status; R0 or R1). Three weekly injections of GI-4000 or placebo were followed by 6 cycles of Gem 1000 mg/m2 iv (day 1, 8, 15 every 28 days). Monthly GI-4000 or placebo were administered on the Gem off-weeks and continued monthly until intolerance, disease recurrence, or death. The primary endpoint is RFS. Data for the 39 R1 subjects (GI-4000 n=19, Placebo n=20) have been unblinded and analyzed. Results: The GI-4000 group had an 11.4 week advantage in median overall survival (524 Days vs 444 Days), 16% advantage in 1 year survival (72% vs 56%), and a 4.6 week advantage in median RFS (287 Days vs 255 days). The GI-4000 group showed a significantly higher rate of mutation specific T cell response to Ras by ELISpot assay; 7/15 (47%) vs 1/12 (8%), p=0.032,with a more pronounced survival benefit in GI-4000 treated immune responders; 21.7 week advantage in median survival (596 Days vs 444 Days) compared to placebo. No significant novel toxicities have been observed to date. Conclusions: GI-4000 in combination with adjuvant Gem showed a clinically meaningful point estimate for the treatment effect on survival in R1 subjects with Ras mutant + pancreas cancer. GI-4000 was immunogenic and well tolerated. Ras specific immune response was associated with a more pronounced benefit in median survival. These data warrant further study in a definitively powered clinical trial for GI-4000 in the adjuvant setting in R1 subjects.

e14654 Background: SHARP was pivotal in determining the safety and efficacy of sorafenib in advanced hepatocellular carcinoma (HCC) in patients with predominately good liver function. In practice, many patients with advanced HCC receive radioembolization (RE). Investigators from the European Network on RE with yttrium-90 resin microspheres (ENRY) group conducted an analysis of safety and survival among consecutive patients who met the SHARP inclusion criteria. Methods: 58% of patients (189 of 325) who had received RE between 09/2003 and 12/2009 were considered SHARP-equivalents. Of these, 11.6% received sorafenib 4.7 months (median) after RE for a median duration of 2.8 months. Safety and tolerability analyses were conducted up to day 90 post RE; changes from baseline were recorded and transitions in CTCAE grades >3 tested. Statistical analyses used SAS (SAS, Cary NC) version 9.2 XP Pro. Results: Like the SHARP sorafenib cohort, most patients had advanced HCC (BCLC stage C: 72.5%), good liver function (Child–Pugh class A: 100%) and ECOG performance status (0–1: 90.5%). Macroscopic vascular invasion (MVI), extrahepatic spread (EHD) or both was present in 33.9%. 20.1% had received prior surgical procedures, 8.5% prior ablative procedures and 33.3% prior vascular [chemo]embolization. RE was predominantly a single whole-liver procedure (median activity 1.7 GBq). Median overall survival was 10.8 months (95% CI: 8.8–12.8) in the SHARP-equivalent cohort, 10.2 months (8.3–11.8) in patients with MVI/EHD, 9.7 months (7.6–10.9) in advanced HCC (BCLC stage C) and 16.6 months (11.2–22.8) in intermediate HCC (BCLC stage B). Treatment-related adverse events (all grades; grade >3) were: fatigue (50.3%; 2.1%), abdominal pain (25.9%; 2.1%), nausea/vomiting (31.2%; 0.5%) and GI ulcer (3.2%; 1.0%). At baseline, raised bilirubin (all grades) was present in 20.3%, increasing to 49.4% of patients evaluated up to day 90. Bilirubin grade was unchanged in 58.1% and increased in 37.8%; 4.0% had ≥grade 3 events. Conclusions: In patients matching the inclusion criteria for SHARP, RE was well tolerated with a median overall survival which compares favorably with sorafenib.

Supramarginal Resection

Current standard of care for glioblastoma is surgical resection followed by temozolomide chemotherapy and radiation. Recent studies have demonstrated that >95% extent of resection is associated with better outcomes, including prolonged progression-free and overall survival. The diffusely infiltrative pattern of growth in gliomas results in microscopic extension of tumor cells into surrounding brain parenchyma that makes complete resection unattainable. The historical goal of surgical management has therefore been maximal safe resection, traditionally guided by MRI and defined as removal of all contrast-enhancing tumor. Optimization of surgical resection has led to the concept of supramarginal resection, or removal beyond the contrast-enhancing region on MRI. This strategy of extending the cytoreductive goal targets a tumor region thought to be important in the recurrence or progression of disease as well as resistance to systemic and local treatment. This approach must be balanced against the risk of impacting eloquent regions of brain and causing permanent neurologic deficit, an important factor affecting overall survival. Over the years, fluorescent agents such as fluorescein sodium have been explored as a means of more reliably delineating the boundary between tumor core, tumor-infiltrated brain, and surrounding cortex. Here we examine the rationale behind extending resection into the infiltrative tumor margins, review the current literature surrounding the use of fluorescein in supramarginal resection of gliomas, discuss the experience of our own institution in utilizing fluorescein to maximize glioma extent of resection, and assess the clinical implications of this treatment strategy.

Genetic Features

Background: Glioblastoma multiforme (GBM) is the most common malignant primary brain cancer in adults. Recent efforts have elucidated genetic features of tumor cells and thus enhanced our knowledge of GBM pathophysiology. The most recent clinical trials report median overall survival between 14 and 20 months. However, real-world outcomes are quite variable and there is a paucity of data within the literature. Methods: Three hundred seventy two GBM patients were diagnosed in the province of British Columbia between January 2013 and January 2015. We have performed a retrospective review on the survival outcomes of the 278 patients who underwent surgical resection as part of the initial treatment. Results: Our results indicate a median age of 61.8y at time of diagnosis with a slight preponderance of males. The median overall survival was 10 months for patients who underwent surgery. As expected, patients over the age of 65 and those with worse initial Karnofsy Performance Status (KPS) scores had a poorer prognosis. Moreover, we have found extent of resection (EOR), treatment strategies and treatment location affect overall survival. Conclusion: The present study highlights factors which affect patient survival after surgery in British Columbia. Our outcomes are slightly worse than survival reported in the US. Variability in pathologic classification and in treatment strategy likely contribute to this difference. Further efforts should ensure access to the gold-standard of care.
