Abstract

Figure S1. MRI at diagnosis. (A) axial, (B) coronal and (C) sagittal section of T1 weighted MRI after contrast administration revealing an intra-extracranial pathologic formation of craniovertebral region 4,4×5,5×5,2 cm in size, which was rapidly enhancing after the gadolinium injection, with decay of bones of craniovertebral region, upper third of processus odontoideus of C2 vertebrae, luxation of cervical vertebrae at the level of atlantoaxial articulation, more profoundly on the right side. Formation grows into the sphenoid bone reaching the brainstem, largely the pons, constrictes foramen of Magendie, compresses the left cerebellar hemisphere and reaches the nasopharyngeal region without entering nasopharyngeal space. Figure S2. MRI after radiotherapy. (A) axial, (B) coronal and (C) sagittal images of T1 weighted MRI after contrast admision performed after surgery and radiation therapy revealed recurrence of the pathologic mass of the craniovertebral junction, up to 5,7×7,1×6,0 cm in size, with central necrosiss. Signs of decay, which replaces clivus, ventral parts of C1-C2, and condyles of temporal bone. Ventrally it infiltrates retropharyngeal space, dorsally deformates and obliterates lumen of pontine cistern and cisterna magna, compressing ventral parts of brainstem. Figure S3. MRI after 4 cycles of denosumab. (A) axial, (B) coronal and (C) sagittal images of T1 weighted MRI after contrast administration with image subtraction (C) after 4 cycles of denosumab treatment revealing an intra-extracranial pathologic formation of craniovertebral region 3,2×6,8×5,2 cm in size, with decay of bones of atlantooccipital and atlantoaxial articulation and upper third of processus odontoideus of C2 vertebrae, with spine offset to the right. The pathological mass enhances after the gadolinium injection, with small hypointense areas, with indicate focal necrosis. The mass grows into the sphenoid bone reaching the brainstem, largely the pons, ventrally reaches nasopharyngeal region without entering nasopharyngeal space. Dorsolateral parts of formation reach condyles of temporal bone, constricts craniovertebral transition and deformates front loop of medulla. The formation is inhomogen due to small parts of cystic transformation. (DOCX 688 kb)

Abstract

BackgroundThe travel distance from home to a treatment centre, which may impact the stage at diagnosis, has not been investigated for retinoblastoma, the most common childhood eye cancer. We aimed to investigate the travel burden and its impact on clinical presentation in a large sample of patients with retinoblastoma from Africa and Europe.MethodsA cross-sectional analysis including 518 treatment-nai¨ve patients with retinoblastoma residing in 40 European countries and 1024 treatment-nai¨ve patients with retinoblastoma residing in 43 African countries.ResultsCapture rate was 42.2% of expected patients from Africa and 108.8% from Europe. African patients were older (95% CI −12.4 to −5.4, p<0.001), had fewer cases of familial retinoblastoma (95% CI 2.0 to 5.3, p<0.001) and presented with more advanced disease (95% CI 6.0 to 9.8, p<0.001); 43.4% and 15.4% of Africans had extraocular retinoblastoma and distant metastasis at the time of diagnosis, respectively, compared to 2.9% and 1.0% of the Europeans. To reach a retinoblastoma centre, European patients travelled 421.8 km compared to Africans who travelled 185.7 km (p<0.001). On regression analysis, lower-national income level, African residence and older age (p<0.001), but not travel distance (p=0.19), were risk factors for advanced disease.ConclusionsFewer than half the expected number of patients with retinoblastoma presented to African referral centres in 2017, suggesting poor awareness or other barriers to access. Despite the relatively shorter distance travelled by African patients, they presented with later-stage disease. Health education about retinoblastoma is needed for carers and health workers in Africa in order to increase capture rate and promote early referral.

Abstract

IMPORTANCE: Early diagnosis of retinoblastoma, the most common intraocular cancer, can save both a child’s life and vision. However, anecdotal evidence suggests that many children across the world are diagnosed late. To our knowledge, the clinical presentation of retinoblastoma has never been assessed on a global scale. OBJECTIVES: To report the retinoblastoma stage at diagnosis in patients across the world during a single year, to investigate associations between clinical variables and national income level, and to investigate risk factors for advanced disease at diagnosis. DESIGN, SETTING, AND PARTICIPANTS: A total of 278 retinoblastoma treatment centers were recruited from June 2017 through December 2018 to participate in a cross-sectional analysis of treatment-naive patients with retinoblastoma who were diagnosed in 2017. MAIN OUTCOMES AND MEASURES: Age at presentation, proportion of familial history of retinoblastoma, and tumor stage and metastasis. RESULTS: The cohort included 4351 new patients from 153 countries; the median age at diagnosis was 30.5 (interquartile range, 18.3-45.9) months, and 1976 patients (45.4%) were female. Most patients (n = 3685 [84.7%]) were from low- and middle-income countries (LMICs). Globally, the most common indication for referral was leukocoria (n = 2638 [62.8%]), followed by strabismus (n = 429 [10.2%]) and proptosis (n = 309 [7.4%]). Patients from high-income countries (HICs) were diagnosed at a median age of 14.1 months, with 656 of 666 (98.5%) patients having intraocular retinoblastoma and 2 (0.3%) having metastasis. Patients from low-income countries were diagnosed at a median age of 30.5 months, with 256 of 521 (49.1%) having extraocular retinoblastoma and 94 of 498 (18.9%) having metastasis. Lower national income level was associated with older presentation age, higher proportion of locally advanced disease and distant metastasis, and smaller proportion of familial history of retinoblastoma. Advanced disease at diagnosis was more common in LMICs even after adjusting for age (odds ratio for low-income countries vs upper-middle–income countries and HICs, 17.92 [95% CI, 12.94-24.80], and for lower-middle–income countries vs upper-middle–income countries and HICs, 5.74 [95% CI, 4.30-7.68]). CONCLUSIONS AND RELEVANCE: This study is estimated to have included more than half of all new retinoblastoma cases worldwide in 2017. Children from LMICs, where the main global retinoblastoma burden lies, presented at an older age with more advanced disease and demonstrated a smaller proportion of familial history of retinoblastoma, likely because many do not reach a childbearing age. Given that retinoblastoma is curable, these data are concerning and mandate intervention at national and international levels. Further studies are needed to investigate factors, other than age at presentation, that may be associated with advanced disease in LMICs.

Abstract

Background: Chemotherapy-induced thrombocytopenia (CIT) is a significant complication of cancer therapy. Data on the optimal management approaches of this morbidity in children and young adults are still limited. Aim: The aim of the study is to estimate the frequency and severity of CIT and associated clinically significant bleeding in children and young adults with solid tumours and haematologic malignancies. Methods: For this retrospective, hospital-based study, children (0-18 y) and young adults (19-40 y) with different types of solid tumours and haematologic malignancies who received chemotherapy at the Muratsan Hospital Complex of Yerevan State Medical University were identified from the patients' database and included in the study (overall 122 patients). Thrombocytopenia was defined as a decrease of platelet count below <100 × 109/L. For assessing bleeding, WHO scale had been used. Results: Overall, the whole group of patients received 430 chemotherapy cycles. During 131 (31.6%) chemotherapy cycles, patients developed CIT. The study revealed a statistically significant inversely proportional correlation between the age and the severity of CIT. Another important finding of the study was that the patients, who previously were exposed to radiation therapy, were more likely to develop CIT, than those who have not received radiation therapy (68% and 28.7%, p = 0.001). From 430 cycles of chemotherapy, 31 (7.2%) cycles reported to have bleeding events. Conclusion: Our study showed that clinically significant thrombocytopenia and bleeding are quite rare among children and young adults. Younger age and previous exposure to radiation therapy are positively correlated with the severity of thrombocytopenia. Larger studies are needed to investigate these findings.

Abstract

KEY POINTS • Synovial sarcomas are often mistreated with unplanned tumor resection. • Attention from specialists early in the course of SS can minimize the risk of recurrence, metastases, and the necessity for resurgery, all of which are increased with unplanned tumor resection. • Chemotherapy alone does not provide sufficient local control of the tumor. • Resurgery, in conjunction with radiotherapy and chemotherapy, is the best choice of management for this patient.
