Abstract
BACKGROUND In the present study, we examined the pattern of metastatic spread in patients with advanced non-small-cell lung cancer (nsclc) and the effect of EGFR mutations. METHODS Patients were identified from a provincial cancer registry, and individual medical records were reviewed. Patients were included if they had stage iv nsclc and underwent diagnostic EGFR mutation testing. Patients were divided into EGFR mutation-positive (EGFR+) and EGFR wild type (wt) cohorts. The primary endpoint was the cumulative incidence for each metastatic site: lung, bone, brain, liver, adrenal glands, distant nodes, and other. Cumulative incidence curves were estimated using a competing-risks method. The secondary outcome was survival. RESULTS Of the 543 identified patients, 121 (22.3%) tested as EGFR+, and 422 (77.7%) tested as EGFR wt. The incidence of brain (39.2% vs. 28.2%, p = 0.038) and lung (61.2% vs. 51.0%, p = 0.048) metastasis was higher in the EGFR+ cohort than in the EGFR wt cohort. In the EGFR+ cohort, a higher incidence of liver metastasis was associated with the exon 21 mutation subtype than with the exon 19 deletion subtype [23% vs. 7%, p < 0.01; hazard ratio (hr): 3.47]. Median survival was significantly longer for the EGFR+ cohort than for the EGFR wt cohort (22.4 months vs. 7.9 months, p < 0.001). In multivariable analysis, brain (hr: 1.73), liver (hr: 1.69), and bone (hr: 1.89) metastases were associated with worse survival. CONCLUSIONS Rates of lung and brain metastases are higher in EGFR mutation carriers, even when adjusted for differences in survival. Brain, liver, and bone metastases are independent negative prognostic factors for survival.

Abstract
The most common benign salivary tumour is a pleomorphic adenoma. Transformation to malignancy, carcinoma ex pleomorphic adenoma (cxpa), occurs in 6% of cases. Management focuses on surgical resection and radiotherapy; however, rare cases require systemic management. We present the case of a 60-year-old woman with a cxpa of the left parotid gland who required systemic therapy for locally recurrent disease. Treatment options were guided by the literature concerning malignant salivary gland tumour and by whole-genome and transcriptome sequencing of the tumour. The patient received multiple systemic agents during the course of her disease, with cyclophosphamide-doxorubicin-cisplatin providing the best control (partial response). Genomeand transcriptome-directed therapy, including sorafenib and vismodegib, were utilized with limited clinical benefit. Malignant transformation in cxpa is a complex process, and therapy directed at a single tumour pathway might not be sufficient to control disease.

Abstract
Nurse navigation is a developing facet of oncology care. The concept of patient navigation was originally created in 1990 at the Harlem Hospital Center in New York City as a strategy to assist vulnerable and socially disadvantaged populations with timely access to breast cancer care. Since the mid-1990s, navigation programs have expanded to include many patient populations that require specialized management and prompt access to diagnostic and clinical resources. Advanced non-small-cell lung cancer is ideally suited for navigation to facilitate efficient assessment in this fragile patient population and to ensure timely results of molecular tests for first-line therapy with appropriately targeted agents. At the BC Cancer Agency, nurse navigator involvement with thoracic oncology triage has been demonstrated to increase the proportion of patients receiving systemic treatment, to shorten the time to delivery of systemic treatment, and to increase the rate of molecular testing and the number of patients with molecular testing results available at time of initial consultation. Insights gained through the start-up process are briefly discussed, and a framework for implementation at other institutions is outlined.

Abstract
AIMS: To explore and validate the utility of rumen endoscopy for collection of rumen papillae for gene expression measurement. METHODS: Four adult Coopworth ewes were fasted for either 4 or 24 hours. Animals were sedated, placed in a dorsally recumbent position at 45 degrees with the head upright, and an endoscope inserted via a tube inserted into the mouth. Biopsies of rumen papillae were taken from the ventral surface of the rumen atrium under visual guidance. Two biopsies were collected from one of the animals that had been fasted for 4 hours, and three from one of the animals that had been fasted for 24 hours. Video of the rumen atrium and reticulum was also collected. The animals recovered uneventfully. Biopsies were subsequently used for extraction and sequencing of mRNA. RESULTS: The ventral surface of the rumen atrium was accessible after 4 hours off pasture, but a larger region was accessible after 24 hours of fasting. Sedation allowed access for endoscope use for around 5 to 10 minutes after which increased saliva flow was noted. Rumen papillae biopsies were easily collected, with samples from a variety of sites collected in the ∼10 minute time window. High quality RNA was obtained for stranded mRNA sequencing. Of the resulting reads, 69–70% mapped uniquely to version 3.1 of the ovine genome, and 48–49% to a known gene. The rumen mRNA profiles were consistent with a previously reported study. CONCLUSIONS: This method for obtaining rumenal tissue was found to be rapid and resulted in no apparent short or long term effects on the animal. High quality RNA was successfully extracted and amplified from the rumen papillae biopsies, indicating that this technique could be used for future gene expression studies. The use of rumen endoscopy could be extended to collection of a variety of rumen and reticulum anatomical measurements and deposition and retrieval of small sensors from the rumen. Rumen endoscopy offers an attractive and cost effective approach to repeated rumen biopsies compared with serial slaughter or use of cannulated animals.
