Strengthening public health policies for childhood cancer: Peru's achievements through the WHO Global Initiative for Childhood Cancer.

Objective: To report the progress in Peru, since June 2019, in the implementation of the World Health Organization Global Initiative for Childhood Cancer using the Cure framework, which can be replicated in low- and middle-income countries.

Methods: A mixed method was used of participatory and documentary evaluation. The participatory evaluation included stakeholders from various government institutions, nonprofit organizations, and international partners.

Systemic lupus erythematosus complicated with macrophage activation syndrome mimicking COVID-19 multisystemic inflammatory syndrome in children.

Background: Macrophage activation syndrome (MAS) is characterized by excessive activation of macrophages and lymphocytes, leading to multiorgan dysfunction. As the initial manifestation of systemic lupus erythematosus (SLE), MAS is rare in children. Due to the COVID-19 pandemic, it is vital to identify the MAS as it shares similar characteristics with the multisystem inflammatory syndrome in children (MIS-C).

ONCOPEDS: A mobile application to improve early diagnosis and timely referral in childhood cancer in a low- and middle-income country-A pilot study.

Background: Diagnosis delay in children and adolescents with cancer is a public health problem in Peru that leads to high rates of advanced disease and mortality. We aimed to assess the implementation feasibility and potential utility of ONCOpeds®, a mobile application that provides consultations with pediatric oncologists, in reducing the latency to diagnosis (LD) and referral time (RT) among children and adolescents in Peru diagnosed with cancer.

Material And Methods: A prospective pilot study was conducted in the region of Callao between November 2017 and April 2018.

Factors associated with the latency to diagnosis of childhood cancer in Peru.

Background: The latency to diagnosis is the time between the detection of a patient's first symptoms and the cancer diagnosis. The aim of this study was to identify the latency to the diagnosis of cancer in children in Peru and the clinical and sociodemographic factors associated with this latency.

Methods: All patients diagnosed with lymphoma and solid tumors between 2012 and 2014 at a social security referral hospital in Peru were retrospectively evaluated.

Endometrioid Paraovarian Borderline Cystic Tumor in an Infant with Proteus Syndrome.

Ovarian and paraovarian neoplasms are uncommon in children, mainly originating from germ cell tumors and, least frequently, epithelial tumors. There is an association between genital tract tumors and Proteus syndrome, a rare, sporadic, and progressive entity, characterized by a postnatal overgrowth in several tissues caused by a mosaic mutation in the AKT1 gene. We describe a 20-month-old asymptomatic infant with Proteus syndrome who developed an endometrioid paraovarian borderline cystic tumor.
