Optimal vascular access strategies for patients receiving chemotherapy for early-stage breast cancer: a systematic review.

IMPORTANCE: Systemic chemotherapy can be administered either through a peripheral vein (IV), or centrally through peripherally inserted central catheter (PICC), totally implanted vascular access devices (PORTs) or tunnelled cuffed catheters. Despite the widespread use of systemic chemotherapy in patients with breast cancer, the optimal choice of vascular access is unknown. OBJECTIVE: This systematic review evaluated complication rates and patient satisfaction with different access strategies for administering neo/adjuvant chemotherapy for breast cancer. EVIDENCE REVIEWED: Ovid Medline, EMBASE and the Cochrane Central Register of Controlled Trials were searched from 1946 to September 2017. Two reviewers independently assessed each citation. The Newcastle-Ottawa scale was used to assess the quality of cohort and case-control studies. FINDINGS: Of 1584 citations identified, 15 unique studies met the pre-specified eligibility criteria. There were no randomised studies comparing types of vascular access. Reports included six single-institution retrospective cohort studies, one retrospective multi-institution cohort, one retrospective cohort database study, five prospective single-institution studies, one prospective multi-institution study and one nested case-control study. Median complication rates were infection: 6.0% PICC (2 studies) versus 2.1% PORT (8 studies); thrombosis: 8.9% PICC (2 studies) versus 2.6% PORT (9 studies); extravasation: 0 PICC (1 study) versus 0.4% PORT (4 studies) and mechanical issues: PICC 3.8% (1 study) versus 1.8% PORT (9 studies). Satisfaction/quality of life appeared high with each device. CONCLUSION: In the absence of high-quality data comparing vascular access strategies, randomised, adequately powered, prospective studies would be required to help inform clinical practice and reduce variation.

Oncology care providers' perceptions and anticipated barriers regarding the use of geriatric assessment in routine clinic practice: A mixed-methods study.

INTRODUCTION: Geriatric assessment (GA) is currently not a standard of cancer care across Canada. In the Canadian province of Saskatchewan, there are no known formal geriatric teams in outpatient oncology settings. Therefore, it is not known whether, how, and to what extent GA is performed in oncology clinics, or what supports are needed to carry out a GA. The objective of this study was to explore Saskatchewan oncology care providers' knowledge, perceptions, and practices regarding GA, and their perceived barriers to implementing formal GA. MATERIALS AND METHODS: In this mixed-methods study, oncology physicians and nurses within the Saskatchewan Cancer Agency (SCA) were invited to participate in an anonymous survey and individual open-ended interview. Quantitative survey data were analyzed using descriptive statistics; free-text responses provided in the survey were summarized. Data from interviews were analyzed using thematic analysis. RESULTS: A total of 19 physicians and 30 clinic nurses participated in the survey (response rate: 24% [physicians] and 38.0% [nurses]). In terms of cancer treatment and management, the majority (74% of physicians and 62% of nurses) stated considerations for older adults are different than younger patients. More than half (53% of physicians and 58% of nurses) reported making treatment and management decisions primarily based on judgement versus validated tools. For physicians whose practices involve prescribing chemotherapy (16/19), 75% rarely or never use validated tools (e.g., CARG, CRASH) to assess risk of chemotoxicity for older patients. Lack of time and supporting staff and feeling unsure as to where to refer older patients for help or follow-up were the most commonly voiced anticipated barriers to implementing GA. Two physicians and six nurses (n = 8) participated in the open-ended interviews. Main themes included: (1) tension between knowing the importance of GA versus capacity and (2) buy-in. DISCUSSION: Our findings review barriers and opportunities for implementing GA in oncology care in Saskatchewan and provides foundational knowledge to inform efforts to promote personalized medicine and to optimize cancer care for older adults with cancer in this region.

Rate of Curative Surgery in Real-world Patients with Unresectable Metastatic Colorectal Cancer Treated with FOLFOXIRI ± Bevacizumab: A Western Canadian Province Experience.

BACKGROUND: Recent evidence from randomized trials suggests that FOLFOXIRI (fluorouracil, oxaliplatin, and irinotecan) ± bevacizumab is associated with higher response rates, with the potential for conversion of unresectable to resectable disease in metastatic colorectal cancer (mCRC). However, limited evidence is available on the efficacy and safety of this regimen in real-world patients with mCRC. The current study aims to evaluate the conversion rate and safety of FOLFOXIRI ± bevacizumab in real-world patients with unresectable mCRC. METHODS: In this retrospective multicenter population-based cohort study, patients who were diagnosed with unresectable mCRC between January 2015 and December 2018 in Saskatchewan and received FOLFOXIRI ± bevacizumab were assessed. Kaplan-Meier survival methods and the log-rank test were performed. RESULTS: A total of 28 eligible patients with a median age of 51 years (interquartile range 39-60) and a male:female ratio of 11:17 were identified; 39% had rectal cancer, 46% had extrahepatic disease, and 46% had bilobar liver metastases. Overall, 63% of the patients had a positive response to FOLFOXIRI ± bevacizumab and 53% underwent metastasectomy. Of all patients 60% had grade 3/4 toxicity and 32% required hospital admission. No treatment-related mortality was noted. After 4 years, 50% of the patients were alive. Median progression-free survival of patients who underwent surgery was 18 months (95% CI 11.3-24.7) versus 11 months (4-18.1) without surgery (p = 0.28). Median overall survival of patients with surgery was 33 months (17.5-48.5) versus 16 months (8.3-23.7) without surgery (p = 0.03). CONCLUSION: The current study suggests that FOLFOXIRI ± bevacizumab therapy in real-world patients with mCRC is associated with a high rate of conversion from unresectable to resectable metastatic disease. Patients with metastasectomy had better survival.

Feasibility of a Remotely Delivered Strength and Balance Training Program for Older Adults with Cancer.

Falls are a major issue among older adults with cancer and lead to interruptions in cancer treatment. Resistance and balance training can prevent falls in older adults, but minimal evidence is available regarding the older cancer population, who often have unique risk factors. We used a pre-post design to assess the feasibility of a remotely delivered exercise program that progressed in difficulty and its efficacy on lower body strength, balance, and falls in older adults with cancer who had prior in-person exercise experience. Twenty-six older adults with cancer completed the intervention. Attendance rate for the virtual component was 97.6% and for the independent component was 84.7%. Participants perceived the program as rewarding and enjoyable (100%), felt this program prepared them to exercise on their own (92%), were confident to continue exercising on their own (81%), and would recommend the program to other patients (100%). The median balance score at baseline and end-of-study was 4 (IQR = 0). The median chair-stand time decreased from 9.2 s (IQR = 3.13) to 7.7 s (IQR = 4.6). A statistically significant difference in lower body strength (r = 0.68, p = 0.001) was detected post-intervention. The findings from this study can inform the design of a larger randomized trial.

Current status of systemic therapy in hepatocellular cancer.

Hepatocellular cancer (HCC) is a common cancer and an important cause of cancer-related death globally. Although surgery is the primary curative treatment, most patients at diagnosis are not surgical candidates and are treated with liver-directed therapy and or systemic therapy. Over the past decade, the systemic treatment options for patients with advanced HCC have evolved. This paper reviews recent progress in systemic therapy and the results of major clinical trials involving novel compounds in patients with HCC. A literature search was performed using keywords related to HCC and systemic therapy. The evidence shows that at the present time an effective adjuvant systemic therapy is not available for patients with early-stage HCC following surgery. In patients with advanced HCC, in addition to sorafenib at least four other targeted agents and several immune checkpoint inhibitors, alone or in combination have been shown to be associated with improved progression-free and overall survival. The optimal sequence of agents, is currently not known, and is determined by patient characteristics, toxicities profile, patients and physicians preference. The future identification of novel active agents and predictive biomarkers are vital to personalize systemic therapy in HCC.

Levamisole-contaminated cocaine: an emergent cause of vasculitis and skin necrosis.

The prevalence of cocaine adulterated with levamisole-induced vasculitis is increasing and physicians should be aware of this unique entity. There have been many reports of cutaneous vasculitis syndrome caused by cocaine which is contaminated with levamisole. Levamisole was used as an antihelminth drug and later was rescinded from use in humans due to adverse effects. Through this paper, we will report a 39-year-old crack cocaine user who presented with purpuric rash and skin necrosis of his ear lobes. Levamisole-induced vasculitis syndrome was suspected. A urine toxicology screen was positive for cocaine, opiates, and marijuana. Blood work revealed positive titres of ANA and p-ANCA, as well as anti-cardiolipin antibody. Biopsy taken from the left ear showed focal acute inflammation, chronic inflammation with thrombus formation, and extravasated blood cells. Treatment was primarily supportive with wound care.
