Femoral to abdomen tunneling at the bedside for medium/long term venous access.

BACKGROUND: Femoral to abdomen tunneling of small-bore central venous catheters is a bedside technique for patients with contraindications to a thoracic approach, or as an alternative to a lower extremity catheter exit site. METHOD: A femoral to abdomen tunneling technique was implemented for patients receiving medium and long-term intravenous treatments with contraindications to the thoracic venous approach or as an alternative to a lower extremity catheter exit site. All venous access devices were inserted with ultrasound guidance under local anesthesia, and catheter tip placement assessed by post procedural radiography. RESULTS: In this case series, from January 2020 to January 2023, a total of eight FTA-tunneled venous access devices were inserted. There were seven ambulatory patients and one bedbound patient. The median length of the subcutaneous tunnel was 20 cm, ranging from 15 to 27 cm. The median length of the intravenous catheter to the terminal tip was 31 cm, ranging from 23 to 40 cm. Tip location was confirmed by post-procedural abdominal radiograph. The catheter tip locations were interpreted to be at the level of T8-T9 (2), T12 (1), L4 (2), L2 (2), L1(1).No insertion or post insertion related complication was reported. Six patients completed the scheduled intravenous treatment. One patient was unable to be tracked due to transfer to an outside facility. One catheter initially demonstrated to be coiled over the left common iliac vessel was repositioned using a high flow flush technique. There was one reported catheter dislodgment by the nurse providing care and maintenance. The overall implant days were 961, with a median dwell time of 125 days ranging from 20 to 399 days. CONCLUSION: Femoral to abdomen tunneling provides an alternative exit site useful in select patients with complex intravenous access. The data of this small retrospective review suggests this a safe and minimally invasive bedside procedure.

Neuroblastoma-associated Opsoclonous Myoclonous Ataxia Syndrome: Profile and Outcome Report on 15 Egyptian Patients.

Opsoclonous myoclonous ataxia syndrome (OMAS) is a rare primarily immune-mediated disease in children. The current study aim was to find out the patterns and outcome of OMAS associated with neuroblastoma (NBL) among Children's Cancer Hospital-Egypt patients. Data was reviewed for 15 eligible patients enrolled between 2007 and 2016. OMAS treatment included prednisolone and cyclophosphamide with/without intravenous immunoglobulin; NBL treatment was given according to risk-corresponding protocol. Patients' age ranged from 0.75 to 12 years at presentation with male/female: 1.1/1. Concurrent diagnosis of OMAS and NBL occurred in 6 patients (40%). OMAS preceded NBL within 0.25 to 2 years in 33%, while NBL preceded OMAS within 0.5 to 1.5 years in 27%. Full OMAS picture was present in 10/15 patients, while 20% presented with truncal ataxia and myoclonus, 1 with truncal ataxia and opsoclonus, and 1 had opsoclonus and myoclonus. Median time till improvement of manifestations was 5 months. The 5-year OMAS progression-free survival was 33.3%, where 10 patients needed second-line therapy due to relapse/progression of OMAS. The median time to progression was 28 months measured from OMAS diagnosis. All patients remained alive with NBL 5-year overall survival of 100% and event-free survival of 85.7% for. However, 73% of the patients showed late sequelae ranging from ocular to cognitive, behavioral and motor disorders; rarely seizures and hemolytic anemia.

Cost-effectiveness of childhood cancer treatment in Egypt: Lessons to promote high-value care in a resource-limited setting based on real-world evidence.

Background: Childhood cancer in low-and middle-income countries is a global health priority, however, the perception that treatment is unaffordable has potentially led to scarce investment in resources, contributing to inferior survival. In this study, we analysed real-world data about the cost-effectiveness of treating 8886 children with cancer at a large resource-limited paediatric oncology setting in Egypt, between 2013 and 2017, stratified by cancer type, stage/risk, and disease status. Methods: Childhood cancer costs (USD 2019) were calculated from a health-system perspective, and 5-year overall survival was used to represent clinical effectiveness. We estimated cost-effectiveness as the cost per disability-adjusted life-year (cost/DALY) averted, adjusted for utility decrement for late-effect morbidity and mortality. Findings: For all cancers combined, cost/DALY averted was $1384 (0.5 × GDP/capita), which is very cost-effective according to WHO-CHOICE thresholds. Ratio of cost/DALY averted to GDP/capita varied by cancer type/sub-type and disease severity (range: 0.1-1.6), where it was lowest for Hodgkin lymphoma, and retinoblastoma, and highest for high-risk acute leukaemia, and high-risk neuroblastoma. Treatment was cost-effective (ratio <3 × GDP/capita) for all cancer types/subtypes and risk/stage groups, except for relapsed/refractory acute leukaemia, and relapsed/progressive patients with brain tumours, hepatoblastoma, Ewing sarcoma, and neuroblastoma. Treatment cost-effectiveness was affected by the high costs and inferior survival of advanced-stage/high-risk and relapsed/progressive cancers. Interpretation: Childhood cancer treatment is cost-effective in a resource-limited setting in Egypt, except for some relapsed/progressive cancer groups. We present evidence-based recommendations and lessons to promote high-value in care delivery, with implications on practice and policy.

Temporal trends in childhood cancer survival in Egypt, 2007 to 2017: A large retrospective study of 14 808 children with cancer from the Children's Cancer Hospital Egypt.

Childhood cancer is a priority in Egypt due to large numbers of children with cancer, suboptimal care and insufficient resources. It is difficult to evaluate progress in survival because of paucity of data in National Cancer Registry. In this study, we studied survival rates and trends in survival of the largest available cohort of children with cancer (n = 15 779, aged 0-18 years) from Egypt between 2007 and 2017, treated at Children's Cancer Hospital Egypt-(CCHE), representing 40% to 50% of all childhood cancers across Egypt. We estimated 5-year overall survival (OS) for 14 808 eligible patients using Kaplan-Meier method, and determined survival trends using Cox regression by single year of diagnosis and by diagnosis periods. We compared age-standardized rates to international benchmarks in England and the United States, identified cancers with inferior survival and provided recommendations for improvement. Five-year OS was 72.1% (95% CI 71.3-72.9) for all cancers combined, and survival trends increased significantly by single year of diagnosis (P < .001) and by calendar periods from 69.6% to 74.2% (P < .0001) between 2007-2012 and 2013-2017. Survival trends improved significantly for leukemias, lymphomas, CNS tumors, neuroblastoma, hepatoblastoma and Ewing Sarcoma. Survival was significantly lower by 9% and 11.2% (P < .001) than England and the United States, respectively. Significantly inferior survival was observed for the majority of cancers. Although survival trends are improving for childhood cancers in Egypt/CCHE, survival is still inferior in high-income countries. We provide evidence-based recommendations to improve survival in Egypt by reflecting on current obstacles in care, with further implications on practice and policy.

Role of surgery in localized initially unresectable neuroblastoma.

PURPOSE: Evaluating the role of surgery and the extent of tumor resection on the outcome of patients with localized initially unresectable neuroblastoma (NB). PATIENTS AND METHODS: This was a retrospective case review study including patients with localized initially unresectable NB. The primary tumor was considered unresectable according to imaging defined risk factors (IDRFs). Surgical resection was attempted after four to six courses of chemotherapy. The extent of resection was classified as follows: ≥90% resection, incomplete resection (50-90%) and cases with <50% resection or just a biopsy. Survival analysis was performed using an intention-to-treat approach. RESULTS: A total of 202 patients with NB were included. Surgical resection was done in 106 patients. It was ≥90% in 89 patients (83.9%). Surgical resection was not performed in 96 patients (47.5%). Fifty-five (57.2%) were in good response after primary chemotherapy and 41 patients (42.7%) had persisting IDRFs, nine of them had biopsy only, and a follow-up strategy was considered in the other 32 patients. The overall 5-year event-free survival (EFS) and overall survival (OS) were 89.1 ± 2.4% and 94.9 ± 1.7%, respectively, with significantly better OS and EFS for patients who had resection versus no resection (p = 0.003 and 0.04, respectively). There was no impact of extent of resection on EFS and OS in the whole group (p = 0.91, p = 0.9) and in subgroup analysis stratified by site, histology, and age of the patients. CONCLUSION: In children with localized initially unresectable NB, surgical resection was the only significant risk factor associated with better survival. The extent of tumor resection had no impact on EFS and OS. The concept of accepting incomplete resection to avoid serious complications was successful.

Survival outcome of intermediate risk neuroblastoma at Children Cancer Hospital Egypt.

AIM: The study aims to evaluate survival outcome in newly diagnosed pediatric intermediate risk neuroblastoma patients treated at the Children Cancer Hospital - Egypt and their relation to various clinical and pathological factors. METHODS: The study included stage 3 patients <1.5 years, children 1.5 years or older with stage 3 disease and favorable histopathological features, infants (<1 year) with International Neuroblastoma Staging System (INSS) stage 4 disease, stage 4 children 1-1.5 years with favorable biology, and infants stage 4 s (with unfavorable biologic features). Patients received systemic chemotherapy, in the form of etoposide and carboplatin alternating with cyclophosphamide, doxorubicin and vincristine, administered at 3-week intervals, with a total of 6 or 8 cycles guided by reaching objective overall response (complete/very good partial/partial response). RESULTS: The study included 136 patients, 67 males and 69 females. 101 patients had abdominal primary tumors, 28 had mediastinal masss and 7 with masses in the neck; 68% were stage 3 and the remaining (n = 44) had metastatic disease. The three-year overall survival (OS) and event-free survival (EFS) estimates were 94% ±â€¯2% and 90.9% ±â€¯2.5%, respectively. OS and EFS by gender, age, pathology and INPC were all statistically not significantly different. Moreover, OS for patients having surgery versus no surgery (inoperable residual only) was statistically significant (98.4% ±â€¯1.6% & 88.7% ±â€¯5.3%, respectively, p = .034). CONCLUSION: A very high rate of survival is currently achievable in patients with intermediate risk neuroblastoma by chemotherapy or chemotherapy and surgery. In addition to response, our plan is to adopt biologically-based treatment to reduce treatment-induced complications among survivors.

A multidisciplinary approach to improving the care and outcomes of patients with retinoblastoma at a pediatric cancer hospital in Egypt.

BACKGROUND: Retinoblastoma poses a substantial burden in developing countries. We conducted this study to assess the effect of implementing a multidisciplinary approach and standardized protocols for treating pediatric patients with retinoblastoma at the Children's Cancer Hospital Egypt (CCHE). MATERIALS AND METHODS: In January 2011, the CCHE implemented standardized protocols for the diagnosis, treatment, and reporting of retinoblastoma cases. The hospital also introduced a new retinoblastoma management algorithm and data analysis system. In this study, we compared the pathologic features, tumor invasiveness, reporting, and survival of 276 pediatric patients who underwent enucleations of 290 eyes before or after the implementation of the retinoblastoma protocols. RESULTS: Time to enucleation (indicating time needed for decision taking) decreased significantly within the neoadjuvant chemotherapy group for intraocular disease after January 2011 (68.7 ± 48 weeks vs. 47.3 ± 28.3 weeks; p < 0.05). Mean optic nerve stump length increased from 5.6 mm in the earlier period to 7.2 mm in the later period (p = 0.004). The overall quality of pathology reporting also improved during the later period. The probability of 3-year survival was significantly higher for patients during the later period (94.2% vs. 79.2%; p = 0.018). CONCLUSIONS: The implementation of standardized protocols and a multidisciplinary approach improved reporting; discrepancies in disease classification and the amount of missing data were reduced; and quality measures and prognostic capabilities of the team were substantially improved. Such established data-driven practice supports faster decision making to enucleate diseased eyes and save patients' lives through providing measurable indicators.

A change roadmap towards research paradigm in low-resource countries: retinoblastoma model in Egypt.

Research on childhood diseases represents a great global challenge. This challenge is maximized in both childhood cancer disciplines and developing world. In this paper, we aim at describing our institution experience in starting a structured childhood cancer research program in one of the developing countries in a short time based on philanthropic efforts. We used retinoblastoma as an example for what was conducted in this program. Starting in 2008, this program included improving clinical practice and its related supporting services besides developing new research services that both complement the clinical activities and pave the way towards creating a research foundation in the country. Results included developing hospital standard treatment protocols, developing national clinical trials, joining international consortia for childhood cancers clinical trials, developing data collection tools and real-time analytics, establishing a biobanking facility, and developing highly qualified team for conducting clinical, epidemiologic, and translational research studies. Moreover, this effort resulted in improving both clinical practice and patients' awareness nationally. This model can be used for other startup facilities that aim at finding answers for their national health problems in low-resource setting.

Low-grade Nonrhabdomyosarcoma Soft Tissue Sarcoma: What is Peculiar for Childhood.

BACKGROUND: Nearly half of soft tissue sarcomas are nonrhabdomyosarcomas (NRSTSs). The low-grade (LG) form comprises a heterogenous group of diseases that rarely metastasize but are known for local recurrence. AIM OF THE STUDY: The aim of the study was to retrospectively evaluate pediatric LG-NRSTS with regard to demography, survival, and factors affecting outcome in Egyptian patients. PATIENTS AND METHODS: The study reviewed 66 NRSTS patients who presented to the Pediatric Oncology Department, National Cancer Institute, Cairo University, between January 2008 and December 2013. RESULTS: Out of the reviewed cases 32 patients had LG tumors and were eligible for analysis. The male to female ratio was 1:1 and the median age was 7.5 years (range, 1 mo to 18 y). Desmoid fibromatosis (N=18) showed frequent local recurrence and nearly half of this group was alive without disease. No recurrence of the disease occurred in the nonfibromatosis group (n=14) and all patients were alive and free of disease. The 5-year overall survival was 88% for the entire group of study patients versus 45% for event-free survival. Tumors >5 cm in diameter and fibromatosis histology subtype were associated with lower EFS. CONCLUSIONS: LG-NRSTS generally has good prognosis, with overall survival reaching 90%. However, aggressive fibromatosis usually runs a poorer course in the form of high incidence of local recurrence and lower survival rates. This needs to be further assessed in larger prospective studies including novel therapies in addition to the current conventional modalities.
