10509 Background: Relapses from high-risk tumors pose a major clinical challenge in pediatric oncology. The German INFORM registry (INdividualized therapy FOr Relapsed Malignancies in children) addresses this problem using integrated next-generation sequencing to rapidly identify patient-specific therapeutic targets. Methods: Whole-exome, low-coverage whole-genome and RNA sequencing is complemented with microarray-based DNA methylation profiling. Identified alterations are discussed and prioritized according to biological significance and potential druggability in a weekly molecular tumor board. Results: To date, 214 tumor samples of high-risk pediatric cancer patients have been profiled from 47 German centers, with 39% being sarcomas, 30% brain tumors, 13% neuroblastoma and 18% hematological or other malignancies. Turnaround time from tissue arrival to molecular results was 21 calendar days on average. In 14/214 patients (7%) we identified an underlying germline predisposition syndrome. In several cases there were discrepancies between the original histological diagnosis and our molecular findings, especially in brain tumors. We detected one or more potentially druggable alterations in 147/214 (69%) cases. Tyrosine kinases, the PI3K/mTOR pathway, MAPK pathway, and cell-cycle as well as transcriptional regulators were commonly affected. Based on these findings, targeted therapeutics were incorporated into the therapy regime in one-third of patients, with anecdotal reports of marked responses, including a patient with a pleomorphic sarcoma, where we detected a previously undescribed RAF-fusion, showing a partial remission upon RAF-inhibition. Conclusions: In summary, real-time comprehensive profiling of pediatric tumors provides valuable diagnostic information and identifies potential therapeutic targets. In parallel, the implementation of a systematic program for reverse-translational evaluation is ongoing. Recently, this nationwide effort has expanded to include patients from other countries. We will also recruit patients to the complementary eSMART and INFORM2 biomarker-driven, phase I/II combination trial series, to provide unprecedented access to targeted therapies in Europe.

Abstract OBJECTIVE: Pediatric oncology patients may require a peripherally inserted central catheter (PICC) for their therapy. Data from adult oncology studies indicate a high risk of complications associated with PICC lines. However, little data exists on the management experience of PICCs in pediatric oncology population. The aim of the present study was to document and analyze the management experience and complications with use of PICC lines in pediatric cancer patients at our center. METHODS: All pediatric cancer patients in the three Maritime Provinces of Nova Scotia, New Brunswick and Prince Edward Island are managed at the IWK health center in Halifax, Nova Scotia in a shared care model with regional hospitals. After ethics approval, all pediatric cancer patients managed at the IWK health center from January 1st 2000 through Dec 31st 2014 who received a PICC line were identified for inclusion in the study. The following databases were used to integrate data on the study patients: (i) pediatric oncology hospital database, (ii) Provincial Cancer in Young People database, (iii) Electronic medical records, (iv) Pharmacy database (v) IWK central line database and (v) Hospital Health records. Patients who received PICC line for an indication not related to their oncologic diagnosis or management were excluded from analysis. SPSS version 22 was used for statistical analysis. RESULTS: A total of 125 PICCs were placed in 102 (11.8%) of the 864 oncology patients. Of these 86 patients received 103 PICCs for oncology related indications. Fifteen (17%) patients required >1 PICC line. For the study cohort, gender ratio was 1:1. The median age at cancer diagnosis was 9.8 years (range: 0-19.3 years). Among the 86 patients who received PICC line, 37% had leukemia, 19% had lymphoma, 13% had brain tumor, 4% had sarcoma, and 28% had other diagnoses. For the first PICC, catheter duration ranged from 0 to 175 days (median 18 days) for a total of 2370 catheter days. The site of insertion was through the antecubital (16%), basilic (31%), brachial (2%), cephalic (41%), jugular (8%), saphenous (2%) veins, and was unknown in 2 patients. In 44% of patients the insertion was through the right side, 56% the left side and was unknown in 2 patients. The indication of the first PICC line included: (i) administration of chemotherapy or bone marrow transplant: 34 (39.5%), (ii) failure of a previous central venous catheter: 15 (17.4%) and (iii) supportive care such as antibiotics, parenteral nutrition or intravenous access: 37 (43.0%). The reasons for removal were as follows: (i) Complications: 24 (28.2%), (ii) elective removal: 55 (64.7%) and (iii) other reasons: 6 (7.1%). Among the 55 PICCs removed electively, 12 (14.0%) were removed at the completion of cancer treatment, 23 (26.7%) at the completion of supportive care, and 20 (23.3%) were replaced with another type of central venous catheter. Among the 24 PICCs removed due to complications, 6 were removed due to infection, 15 due to mechanical complications and 3 due to thrombosis. CONCLUSION: We found that PICC lines are frequently used in pediatric cancer patients for a variety of indications. Seventeen percent of the patients needed >1 PICC line. Further, close to 1/3rd of the patients experienced a complication related to their PICC line. Our experience highlights the need to conduct further studies addressing (i) indications of PICC line insertion in pediatric oncology (ii) determination of causes of PICC line related complications to help guide PICC line indications. Identifying patients at high risk of PICC line related complications will aid judicious choice of PICC line in pediatric cancer patients. Disclosures No relevant conflicts of interest to declare.

One of the most common complications of cancer chemotherapy is oral mucositis. This study evaluates the therapeutic effects of honey with the focus on grade III and IV oral mucositis, reduction of bacterial and fungal infections, duration of episodes of oral mucositis, and body weight in pediatric leukemic patients undergoing chemo/radiotherapy. This is an open labeled randomized controlled study conducted at our hospital on 40 pediatric cancer patients undergoing chemo/radiotherapy. All the 40 patients included in this study experienced a sum total of 390 episodes of fever and neutropenia associated with oral mucositis. A significant reduction of oral mucositis, associatedCandida, and aerobic pathogenic bacterial infections was noted in patients in the honey treatment group. Also, there is a significant decrease in the duration of hospitalization for all those in the treatment group combined with a significant increase of body weight, delayed onset, and decreased severity of pain related to oral mucositis. Complications of oral mucositis can be tremendously reduced by the topical application of local Saudi honey and honey should be used as an integrative approach in prophylaxis and treatment of chemo/radiotherapy-induced oral mucositis in pediatric cancer patients. Further research is needed to elucidate and better understand the underlying mechanism.
