Studies looking at the benefit of surgery at first relapse (second surgery) for recurrent glioblastoma were confounded by including patients with varying grades of glioma, performance status and extent of resection. This case-controlled study aims to remove these confounders to assess the survival impact of second surgery in recurrent glioblastoma. Retrospective data on patients with glioblastoma recurrence at two tertiary Australian hospitals from July 2009 to April 2015 was reviewed. Patients who had surgery at recurrence were matched with those who did not undergo surgery at recurrence, based on the extent of their initial resection and age. Overall survival (OS1 assessed from initial diagnosis and OS2 from the date of recurrence) as well as functional outcomes after resection were analysed. There were 120 patients (60 in each institution); median age at diagnosis was 56 years. Median OS1 was 14 months (95% CI 11.5-15.7) versus 22 months (95% CI 18-25) in patients who did not undergo second surgery and those with surgery at recurrence. OS2 was improved by second surgery (4.7 vs 9.6, HR 0.52, 95% CI 0.38-0.72, P < 0.001), and by chemotherapy, given at recurrence, (HR 0.47, 95% CI 0.24-0.92, P = 0.03). After second surgery, 80% did not require rehabilitation and 61% were independently mobile. Second surgery for recurrent glioblastoma was associated with a survival advantage. Chemotherapy independent of surgery, also improved survival. Functional outcomes were encouraging. More research is required in the era of improved surgical techniques and new antineoplastic therapies.
Background The therapeutic landscape in medical oncology continues to expand significantly. Newer therapies, especially immunotherapy, offer the hope of profound and durable responses with more tolerable side effect profiles. Integrating this information into the decision making process is challenging for patients and oncologists. Systemic anticancer treatment within the last thirty days of life is a key quality of care indicator and is one parameter used in the assessment of aggressiveness of care. Methods A retrospective review of medical records of all patients previously treated at Goulburn Valley Health oncology department who died between 1 January 2015 and 30 June 2018 was conducted. Information collected related to patient demographics, diagnosis, treatment, and hospital care within the last 30 days of life. These results were presented to the cancer services meeting and a quality improvement intervention program was instituted. A second retrospective review of medical records of all patients who died between 1 July 2018 and 31 December 2018 was conducted in order to measure the effect of this intervention. Results The initial audit period comprised 440 patients. 120 patients (27%) received treatment within the last 30 days of life. The re-audit period comprised 75 patients. 19 patients (25%) received treatment within the last 30 days of life. Treatment rates of chemotherapy reduced after the intervention in contrast to treatment rates of immunotherapy which increased. A separate analysis calculated the rate of mortality within 30 days of chemotherapy from the total number of patients who received chemotherapy was initially 8% and 2% in the re-audit period. Treatment within the last 30 days of life was associated with higher use of aggressive care such as emergency department presentation, hospitalisation, ICU admission and late hospice referral. Palliative care referral rates improved after the intervention. Conclusion This audit demonstrated that a quality improvement intervention can impact quality of care indicators with reductions in the use of chemotherapy within the last 30 days of life. However, immunotherapy use increased which may be explained by increased access and a better risk benefit balance.
Purpose: To assess the efficacy and safety of dual antiangiogenesis agents, bevacizumab plus trebananib, without chemotherapy, in first-line treatment of metastatic colorectal cancer (mCRC). Patients and Methods: This open-label phase II study enrolled patients with unresectable mCRC with no prior systemic treatment. All patients received bevacizumab 7.5 mg/kg 3-weekly and trebananib 15 mg/kg weekly. The primary endpoint was disease control [stable disease, partial response (PR), or complete response (CR)] at 6 months (DC6m). Secondary endpoints included toxicity, overall response rate (ORR), progression-free survival (PFS), and overall survival (OS). Exploratory biomarkers in plasma angiogenesis–related proteins, tumor gene expression, and plasma antibodies to tumor antigens were examined. Results: Forty-five patients were enrolled from four Australian sites. DC6m was 63% [95% confidence interval (CI), 47–77]. ORR was 17% (95% CI, 7–32), comprising of seven PRs. Median duration of response was 20 months (range, 10–48 months). Median PFS was 8.4 months and median OS 31.4 months. Grade 1–2 peripheral edema and joint-related symptoms were common. Overall incidence of grade 3–4 adverse events (AE) of any type was 33% (n = 15). Expected AEs of bevacizumab treatment did not appear to be increased by the addition of trebananib. Conclusions: In a first-line mCRC population, the dual antiangiogenic combination, bevacizumab plus trebananib, without chemotherapy, was efficacious with durable responses. The toxicity profile of the combination was manageable and did not exceed that expected with bevacizumab +/− chemotherapy. Exploratory biomarker results raise the hypothesis that the antiangiogenic combination may enable the antitumor immune response in immunotolerant colorectal cancer.

Background Febrile neutropenia is a serious complication of chemotherapy. The Multinational Association for Supportive Care in Cancer (MASCC) risk index score identifies patients at low risk of serious complications. Outpatient management programs have been successfully piloted in other Australian metropolitan cancer centers. Aim To assess current management of febrile neutropenia at our regional cancer center and determine potential impacts of an outpatient management program. Method We performed a retrospective review of medical records for all patients admitted at our regional institution with febrile neutropenia between 1 January 2016, and 31 December 2018. We collected information regarding patient characteristics, determined the MASCC risk index score, and if low risk, we determined the eligibility for outpatient care and potential reduction in length of stay and cost benefit. Results A total of 98 hospital admissions were identified. Of these, 66 had a MASCC low‐risk index score. Fifty‐eight patients met the eligibility criteria for outpatient management. Seventy‐one percent were female. The most common tumor type was breast cancer. Forty‐eight percent were treated with curative intent. The median length of stay was 3 days. The median potential reduction in length of stay for each admission was 2 days. The total potential reduction in length of stay was 198 days. No admission resulted in serious complications. Conclusion This review demonstrates a significant number of hospital admission days can be avoided. We intend to conduct a prospective pilot study at our center to institute an outpatient management program for such low‐risk patients with potential reduction in hospital length of stay. This will have significant implications on health resource usage, service provision planning, and patient quality of life.
