Background Detailed epidemiology for patients with advanced metastatic melanoma in Canada is not well characterized. We conducted an analysis of patients with this disease in the province of Ontario, with the aim being to study the presentation, disease characteristics and course, and treatment patterns for malignant melanoma.Methods In this Canadian observational prospective and retrospective study of patients with malignant melanoma, we used data collected in the Canadian Melanoma Research Network (cmrn) Patient Registry. We identified patients who were seen at 1 of 3 cancer treatment centres between April 2011 and 30 April 2013. Patient data from 2011 and 2012 were collected retrospectively using chart records and existing registry data. Starting January 2013, data were collected prospectively. Variables investigated included age, sex, initial stage, histology, mutation type, time to recurrence, sites of metastases, resectability, and previous therapies.Results A cohort of 810 patients with melanoma was identified from the cmrn registry. Mean age was 58.7 years, and most patients were men (60% vs. 40%). Factors affecting survival included unresectable or metastatic melanoma, initial stage at diagnosis, presence of brain metastasis, and BRAF mutation status. The proportion of surviving patients decreased with higher initial disease stages.Conclusions Using registry data, we were able to determine the detailed epidemiology of patients with melanoma in the Canadian province of Ontario, validating the comprehensive and detailed information that can be obtained from registry data.

(1) Background: Tumor recurrence after liver resection (LR) for intrahepatic cholangiocarcinoma (ICC) is common. Repeat liver resection (RLR) for recurrent ICC results in good survival outcomes in selected patients. The aim of this study was to investigate factors affecting the chance of resectability of recurrent ICC. (2) Methods: LR for ICC performed between January 2001 and December 2020 were retrospectively reviewed. Patients who had undergone first LR were considered for the study. Data on recurrences were analyzed. A logistic regression model was used for multivariable analysis of factors related to RLR rate. (3) Results: In total, 140 patients underwent LR for ICC. Major/extended hepatectomies were required in 105 (75%) cases. The 90-day mortality was 5.7%, Clavien–Dindo grade 3, 4 complications were 9.3%, N+ disease was observed in 32.5%, and the median OS was 38.3 months. Recurrence occurred in 91 patients (65%). The site of relapse was the liver in 53 patients (58.2%). RLR was performed in 21 (39.6%) patients. Factors that negatively affected RLR were time to recurrence ≤12 months (OR 7.4, 95% CI 1.68–33.16, p = 0.008) and major hepatectomy (OR 16.7, 95% CI 3.8–73.78, p < 0.001) at first treatment. Survival after recurrence was better in patients who underwent RLR as compared with not resected patients (31 vs. 13.2 months, p = 0.02). (4) Conclusions: Patients with ICC treated at first resection with major hepatectomy and those who recurred in ≤12 months had significantly lower probability to receive a second resection for recurrence.

Abstract Objects’ measurements often boil down to the determination of changes due to external factors affecting on their structure. The estimation of changes in a tested object, in addition to proper measuring equipment, requires the use of appropriate measuring methods and experimental data result processing methods. This study presents a statement of results of geometrical measurements of a steel cylinder that constitutes the main structural component of the historical weir Czersko Polskie in Bydgoszcz. In the initial stage, the estimation of reliable changes taking place in the cylinder structure involved the selection of measuring points essential for mapping its geometry. Due to the continuous operation of the weir, the points covered only about one-third of the cylinder area. The set of points allowed us to determine the position of the cylinder axis as well as skews and deformations of the cylinder surface. In the next stage, the use of methods based on artificial neural networks allowed us to predict the changes in the tested object. Artificial neural networks have proved to be useful in determining displacements of building structures, particularly hydro-technical objects. The above-mentioned methods supplement classical measurements that create the opportunity for carrying out additional analyses of changes in a spatial position of such structures. The purpose of the tests is to confirm the suitability of artificial neural networks for predicting displacements of building structures, particularly hydro-technical objects.

Abstract Carbon dissolution from four types of metallurgical cokes and graphite was investigated by using immersion rods in a resistance furnace to clarify the influence of factors governing the rate of carbon dissolution from carbonaceous materials into Fe–Mn melts at 1550 °C. The factors studied were the microstructure of carbonaceous materials, roughness, porosity and the wettability between carbonaceous materials and the melt. Carbon/metal interface was characterised by scanning electron microscopy accompanied with energy-dispersive X-ray spectrometry to investigate the formation of an ash layer. The results showed that coke E had the highest dissolution rate. Surface roughness and porosity of the carbonaceous materials seemed to be dominant factors affecting the dissolution rates. Further, crystallite size did not have a significant effect on the dissolution rates. Solid/liquid wettability seemed to affect the initial stage of dissolution reaction. The dissolution mechanism was found to be both mass transfer and interfacial reactions.

467 Background: Clinical trials have shown that tumor KRAS status predicts response to anti-EGFR monoclonal antibodies in metastatic colorectal cancer (mCRC). We sought to compare distribution of wild-type and mutated KRAS in an Irish population and identify clinicopathologic correlates. Methods: From our prospectively maintained database we retrospectively identified patients with mCRC and documented KRAS status between Jan 2007 to June 2010. Medical notes were examined for patient demographics and disease characteristics. Variables were extracted and compared using unpaired t test and chi2 test. Results: 52 patients were identified, 29 (55.8%) with mutated (mt) and 23 (44.2%) with wild type (wt) KRAS from tumor tissue. Males accounted for 61.5% (n=31). Median age at diagnosis of metastatic disease for the KRASmt group was 66.4 years (range 56.7-82.1) and for the KRAS wt group was 64.2 years (40.1-76.8), p= 0.08. 21 (72.4%) of the KRASmt group and 16 (69.6%) of the KRASwt group had metastatic disease at presentation (p=0.81). For patients who presented initially with localised disease, time to development of metastases was 22.5mo (range 14-37.6) for the KRASmt group and 16.7mo (3.2-123.7) for the KRASwt (p=0.30). 21 (72.4%) of KRASmt and 17 (74.1%) of KRASwt tumors had left-sided primary (p = 0.84) with equal numbers of primary tumor resection in both groups. There was no statistical difference in TN-stage or the presence of liver metastases. Numbers of patients with KRASmt tumors with one, two and three or more different sites of metastases was 22 (75.9%), 5 (17.2%), and 2 (6.9%), and in KRASwt tumors there was no significant difference: 18 (78.3%), 4 (17.4%), and 1 (4.3%), respectively (p = 0.93). Median CEA at diagnosis for both groups were 19.7 μg/l (range 1.2-5958) and 6.1 (1.3-696.9; p = 0.11). Conclusions: We found that the ratio of KRASmt to KRASwt tumours in an Irish population is comparable to that in large international trials. Our analysis revealed no association between KRAS status and clinicopathologic variables. The inclusion of BRAF status, not readily available in our institution, may help define poor prognosis tumors. At present there is no validated molecular biomarker that is superior to standard clinicopathologic variables. No significant financial relationships to disclose.

9030 Background: Activating mutations of BRAF V600 can be found in 40%-50% of melanomas and are related to poor prognosis. In a phase 3 trial for the treatment of metastatic melanoma (MM) in chemotherapy-naive patients, nab-paclitaxel (nab-P) vs dacarbazine (DTIC) demonstrated a significant improvement in the primary endpoint of progression-free survival (PFS), assessed by independent radiological review (IRR), and a trend toward prolonged overall survival (OS) at the interim survival analysis. The study also explored the effect of BRAF status on the efficacy parameters. Methods: Chemotherapy-naive patients with stage IV melanoma (M1c stage 65%; elevated LDH 28%) and ECOG performance status 0-1 were randomized to nab-P 150 mg/m2 on days 1, 8, and 15 of a 28-day cycle (n = 264) or DTIC 1000 mg/m2 on day 1 of each 21-day cycle (n = 265) independent of BRAF status. Prespecified subgroup analyses of final PFS and interim OS in subgroups by BRAF status (V600E mutant, wild-type, or unknown) were performed. Results: BRAF mutation status was balanced between the treatment arms, with 36% and 38% of patients with known BRAF mutation status in the nab-P and DTIC arms, respectively. Patient characteristics were also balanced within BRAF subgroups. As shown in the Table, advantage in the nab-P arm vs DTIC arm was observed for both PFS and interim OS regardless of BRAFmutation status. Poststudy BRAF inhibitor treatment was also balanced. Conclusions: In this phase III trial, treatment effect was independent of BRAF mutation status, benefiting all patients who received nab-P vs DTIC. Therefore nab-P should be considered in the armamentarium for all chemotherapy-naive patients with MM. Clinical trial information: NCT00864253. [Table: see text]
