We report updated overall survival (OS) data from study NO16966, which compared capecitabine plus oxaliplatin (XELOX) vs 5-fluorouracil/folinic acid (FOLFOX4) as first-line therapy in metastatic colorectal cancer. NO16966 was a randomised, two-arm, non-inferiority, phase III comparison of XELOX FOLFOX4, subsequently amended to 2 × factorial design with further randomisation bevacizumab or placebo. A planned follow-up exploratory analysis OS performed. The intent-to-treat (ITT) population...

Sunitinib, a new vascular endothelial growth factor receptor inhibitor, has demonstrated high activity in renal cell carcinoma (RCC) and is now widely used for patients with metastatic disease. Although generally well tolerated associated low incidence of common toxicity criteria grade 3 or 4 toxicities, sunitinib exhibits distinct pattern novel side effects that require monitoring management. This article summarizes the most important proposes recommendations their monitoring, prevention...

PURPOSE: The time spent in pursuing treatments for advanced cancer can be substantial. We have previously proposed a pragmatic and patient-centered metric of these costs—which we term toxicity—as any day with physical health care system contact. This includes outpatient visits (eg, bloodwork, scans, etc), emergency department visits, overnight stays facility. Herein, sought to assess toxicity completed randomized controlled trial (RCT). METHODS: conducted secondary analysis the Canadian...

Thyroid cancer management is rapidly changing. The identification of actionable biomarkers through both germline and somatic testing are now an integral part directing patient management. However, deficiencies disparities within existing thyroid biomarker test approaches resulting in inconsistent application for care. An expert panel was convened to create consensus algorithms recommendations on patients diagnosed with medullary cancer, non-anaplastic follicular cell-derived or anaplastic...

Patient access to new oncology drugs in Canada is only possible after navigating multiple sequential systemic checkpoints for national regulatory approval, health technology assessment (HTA) and collective government price negotiation. These steps delay prevent care providers from being able prescribe optimal therapy. Eighteen Canadian clinicians the medicine, nursing pharmacy professions met develop consensus recommendations defining reasonable performance standards around process...

4030 Background: In a phase II study in untreated MCRC patients, XELOX (capecitabine + oxaliplatin) appeared to have similar efficacy compared with previously published FOLFOX4 data [1]. We therefore started III 2-arm open-label non-inferiority comparing FOLFOX4. 2003 the addition of bevacizumab (Bev) irinotecan/5-FU/LV was shown improve progression-free survival (PFS) and overall [2]. then amended our trial 2x2 partially blinded assess Bev. Methods: Original study: (oxaliplatin 130 mg/m 2...

Abstract Introduction Although contact days—days with health-care outside home—are increasingly adopted as a measure of time toxicity and treatment burden, they could also serve surrogate treatment-related harm. We sought to assess the association between days patient-reported outcomes prognostic ability days. Methods conducted secondary analysis CO.17 that evaluated cetuximab vs supportive care in patients advanced colorectal cancer. collected European Organisation for Research Treatment...

Globally, hepatocellular carcinoma (hcc) is the third most common cause of death from cancer, after lung and stomach cancer. The incidence hcc in Canada increasing expected to continue increase over next decade. Given high mortality rate associated with hcc, steps are required mitigate impact disease. To address this challenging situation, a panel 17 experts, representing gastroenterologists, hepatologists, hepatobiliary surgeons, medical oncologists, pathologists, radiologists across...

Patients mCRC who had progressed following first-line therapy were randomised 1 : to modified (m)FOLFOX6 plus cediranib (20 or 30 mg day−1) bevacizumab (10 kg−1 every 2 weeks).

Well-differentiated neuroendocrine tumours (nets-previously called "carcinoid tumours") are relatively rare originating from the diffuse system; they found most often in bronchial or gastrointestinal systems. In Canada, gastroenterohepatic NETS represent less than 0.25% of oncology cases. Because relative rarity these tumours, diagnostic and therapeutic approaches vary based on individual physician experience. A number European North American groups have developed consensus guidelines for...

Response assessment in advanced pancreatic cancer (APC) is difficult and predictive markers are needed. There insufficient data on the value of carbohydrate antigen 19–9 (CA 19-9) cytostatic-targeted therapies. Axitinib, a selective vascular endothelial growth factor (VEGF) receptors 1, 2, 3 inhibitor, may increase overall survival (OS) APC. We assessed serum CA 19-9, clinical outcomes diastolic blood pressure (dBP) APC patients receiving gemcitabine plus axitinib (Gem+A) or alone. In total...

Monoclonal antibodies against the epidermal growth factor receptor (anti-egfr) when used in treatment of metastatic colorectal cancer are associated with improved survival. Patients whose tumours harbor a KRAS mutation codon 12 or 13 have been shown not to benefit from anti-egfr antibodies.

In recent years, significant advances have been made in the management of metastatic colorectal cancer. Traditionally, an improvement overall survival has considered “gold standard”—the most convincing measure efficacy. However, requires larger patient numbers and longer follow-up may often be confounded by other factors, including subsequent therapies crossover. Given number active for potential investigation, demand rapid evaluation early availability new is growing. Progression-free...

Further, recent SEER data suggests a mortality difference between that varies by stage: stage II III having lower higher mortality, respectively.
