Development of a template for operative reporting of pediatric cancer surgery in limited-resource settings by using a modified Delphi method.

PURPOSE: A comprehensive operative report for cancer surgery is crucial for accurate disease staging, risk stratification, and therapy escalation/de-escalation, which affects the outcome. Narrative operative reports may fail to include some critical findings. Furthermore, standardized operative reports can form the basis of a local registry, which is often lacking in limited-resource settings (LRSs). In adult literature, synoptic operative reports (SOR) contain more key findings than narrative operative reports. In the LRSs, where the capacity of diagnostic pathology services is typically suboptimal, the value of a thorough operative report is even greater. The aim of this study was to develop a SOR template to help standardize childhood cancer surgery reporting in LRSs. METHODS: Twenty-three experts in pediatric cancer with extensive experience practicing in LRSs were invited to participate in a modified Delphi procedure. SOR domains for pediatric oncology surgery were drafted based on a literature search and then modified based on experts' opinions. The experts anonymously answered multiple rounds of online questionnaires until all domains and subdomains reached a consensus, which was predefined as 70% agreement. RESULTS: Sixteen experts participated in the study, and two rounds of the survey were completed. Twenty-one domains were considered relevant, including demographics, diagnosis, primary site, preoperative disease stage, previous tumor biopsy or surgery, preoperative tumor rupture, neoadjuvant therapy, surgical access, type of resection, completeness of resection, tumor margin assessment, locoregional tumor extension, organ resection, intraoperative tumor spillage, vascular involvement, lymph node sampling, estimated blood loss, intraoperative complications and interventions to address them, specimen names, and specimen orientation. CONCLUSION: We developed a SOR template for pediatric oncology surgery in LRSs. Consensus for all 21 domains and associated subdomains was achieved using a modified Delphi procedure.

Evidence-based surgical guidelines for treating children with Wilms tumor in low-resource settings.

BACKGROUND: Survival of Wilms tumor (WT) is > 90% in high-resource settings but < 30% in low-resource settings. Adapting a standardized surgical approach to WT is challenging in low-resource settings, but a local control strategy is crucial to improving outcomes. OBJECTIVE: Provide resource-sensitive recommendations for the surgical management of WT. METHODS: We performed a systematic review of PubMed and EMBASE through July 7, 2020, and used the GRADE approach to assess evidence and recommendations. RECOMMENDATIONS: Initiation of treatment should be expedited, and surgery should be done in a high-volume setting. Cross-sectional imaging should be done to optimize preoperative planning. For patients with typical clinical features of WT, biopsy should not be done before chemotherapy, and neoadjuvant chemotherapy should precede surgical resection. Also, resection should include a large transperitoneal laparotomy, adequate lymph node sampling, and documentation of staging findings. For WT with tumor thrombus in the inferior vena cava, neoadjuvant chemotherapy should be given before en bloc resection of the tumor and thrombus and evaluation for viable tumor thrombus. For those with bilateral WT, neoadjuvant chemotherapy should be given for 6-12 weeks. Neither routine use of complex hilar control techniques during nephron-sparing surgery nor nephron-sparing resection for unilateral WT with a normal contralateral kidney is recommended. When indicated, postoperative radiotherapy should be administered within 14 days of surgery. Post-chemotherapy pulmonary oligometastasis should be resected when feasible, if local protocols allow omission of whole-lung irradiation in patients with nonanaplastic histology stage IV WT with pulmonary metastasis without evidence of extrapulmonary metastasis. CONCLUSION: We provide evidence-based recommendations for the surgical management of WT, considering the benefits/risks associated with limited-resource settings.
