To determine the demographic and systemic parameters in children with solid malignancies and to ascertain which of them affected the delay in diagnosis, a retrospective study was performed on 315 children diagnosed with a solid tumor at our hospital, including epidemiological, social, and medical issues concerning the family, the child, the medical system, and the tumor. Lag time, defined as the interval between onset of symptoms and final diagnosis, including parent delay and physician delay, was estimated for each child. Mean lag time: 15.75 weeks (w), median: 7 w, range: 0-208 w. Lowest mean values appeared in kidney tumors, highest in epithelial, brain and soft tissue sarcomas. Mean parent delay: 4.42 w, median: 1 w, range: 0-130 w. Mean physician delay: 11.17 w, median: 4 w, range: 0-206 w. Among the demographic and personal parameters, the best predictors for diagnosis delay were age of child and father's ethnic origin. Several factors influenced diagnosis delay of childhood solid tumors. Recognizing these factors could minimize the delay, thereby improving the child's chances of survival.

Twenty-one pediatric retinoblastoma (RB) patients treated between 1976 and 1994 were evaluated for late treatment-related complications. Median age at diagnosis was 24 months; median age at follow-up was 12 years; median follow-up time was 12 years. Of the 21 patients, 14 had unilateral RB and 7 had bilateral RB. Thirteen patients had received external radiotherapy and 8 children were treated by chemotherapy. Twenty-one patients had undergone enucleation. Radiation-induced cataracts were found in 3 patients, radiation retinopathy in 1, enucleation and postradiotherapy contracted socket in 1, very low visual acuity postradiotherapy in 3, severe hypotelorism in 2, growth hormone deficiency in 2, neurocognitive disorders in 6, and orbital deformation due to radiation bone atrophy was moderate-severe in 12 patients. Azoospermia was found in 1 patient treated by cyclophosphamide and vincristine. The most frequent sequela in this group of RB-cured children were postradiotherapy orbital deformation due to bone atrophy and neurocognitive disabilities. Late radiation effects must be avoided by using modern, innovative, and more sophisticated radiotherapeutic techniques. Late treatment-related complications justify the long-term follow-up of childhood RB survivors.
Over the past 22 years, 16 children with thyroid carcinoma were referred to the Northern Israel Oncology Center. All patients had undergone surgical procedures, either total or subtotal thyroidectomy, and 7 patients had undergone cervical lymph node dissections. Postoperatively, 5 patients underwent thyroid ablation with radioactive 131I as first treatment. Two patients received postoperative external radiation therapy to a field encompassing the cervical region, superior mediastinum, and both supraclavicular grooves. After a median follow-up of 60 months (range, 5-169 months), all patients are alive with no evidence of recurrent disease. Two patients who had recurrences, one in the submaxillary lymph nodes and one in the lungs, were salvaged successfully with retreatment with 131I therapy. No severe acute or long-term side effects were exhibited. The long-term results of treatment of pediatric thyroid carcinoma are excellent, but there remains disagreement over the extent of surgical and postsurgical treatment required.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
