Filter by:This study aims to prospectively document the population characteristics, imaging findings, pathological features, prognostic factors, etc., of patients with mediastinal tumors. Clinical information will be structured and processed, and it is recommended to establish a mediastinal tumors database at Peking Union Medical College Hospital. The goal is to provide support for the quality of diagnosis and treatment, clinical protocols, and medical decision-making related to mediastinal tumors.
Sacrococcygeal teratoma is one of the most common tumors that occur in the neonatal period. It presents either as a mass protruding from the sacrococcygeal region or as a pelviabdominal mass according to the type. Surgical excision is the main treatment, most masses are benign, however some are malignant and require radiotherapy or chemotherapy. Complications may occur due to pressure resulting from the tumor growth in the fetal period, or due to damage to important near tissues during surgical excision. Postoperative complications may be urinary as neurogenic bladder, Lower gastrointestinal as constipation, soiling or incontinence. In this work we study the outcomes of fecal continence through a questionnaire and its effect on the quality of life of the affected children.
A Non-Therapeutic Study that aims to establish a cohort of GCT survivors to understand short term and long-term adverse effects of treatment and to conduct molecular analyses to improve risk stratification.
The aim of this study was to evaluate the diagnostic efficacy of computer aided diagnostic tool for neck masses using machine learning and deep learning techniques on clinical information and radiological images in children.
Sacrococcygeal teratomas are the most common neonatal tumors and require rapid and complete resection. Tumor nerve compression and pelvic surgical sequelae may lead to many and varied voiding disorders. Data concerning long-term vesico-sphincteric disorders are conflicting. Some studies find good functional results [Cozzi et al., 2008; Draper et al., 2009]. However other authors reveal neurologic bladder with detrusor sphincter dyssynergia [Hambraeus et al., 2018] and rise concerned about long-term renal function [Khanna et al., 2019; Rehfuss et al., 2020] even in the absence of clinical voiding disorders. Most of studies include young patients with other malformations such as anorectal malformations or dysraphisms which may impact the results. The main objective is to assess bladder dysfunction in children aged 6 to 18 years after isolated sacrococcygeal teratoma resection.
The aim of this study was to evaluate the diagnostic efficacy of computer aided diagnostic tool for retroperitoneal tumor using machine learning and deep learning techniques on computed tomography images in children.
This phase II trial studies the best approach to combine chemotherapy and radiation therapy (RT) based on the patient's response to induction chemotherapy in patients with non-germinomatous germ cell tumors (NGGCT) that have not spread to other parts of the brain or body (localized). This study has 2 goals: 1) optimizing radiation for patients who respond well to induction chemotherapy to diminish spinal cord relapses, 2) utilizing higher dose chemotherapy followed by conventional RT in patients who did not respond to induction chemotherapy. Chemotherapy drugs, such as carboplatin, etoposide, ifosfamide, and thiotepa, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Radiation therapy uses high energy x-rays or high-energy protons to kill tumor cells and shrink tumors. Studies have shown that patients with newly-diagnosed localized NGGCT, whose disease responds well to chemotherapy before receiving radiation therapy, are more likely to be free of the disease for a longer time than are patients for whom the chemotherapy does not efficiently eliminate or reduce the size of the tumor. The purpose of this study is to see how well the tumors respond to induction chemotherapy to decide what treatment to give next. Some patients will be given RT to the spine and a portion of the brain. Others will be given high dose chemotherapy and a stem cell transplant before RT to the whole brain and spine. Giving treatment based on the response to induction chemotherapy may lower the side effects of radiation in some patients and adjust the therapy to a more efficient one for other patients with localized NGGCT.
Sacrococcygeal teratoma (SCT) is the most common fetal and neonatal tumor. However, predicting factors of evolution, sequelae and relapse are still unreliable because of small-cohort studies. This study aims at identifying prenatal and postnatal prognostic factors of evolution of SCT during pregnancy, of postnatal relapse, and of medium and long-term sequelae (urinary, digestive, esthetic, psychologic) in order to improve parental counseling when the diagnosis of SCT is made during pregnancy.
A tumor comprising of different types of tissues (such as hair, muscle, bone, etc.) is known as a teratoma. It is a type of germ cell (cells that make sperm or eggs) tumor. When these germ cells have rapid cancerous growth, then such a teratoma is called a malignant teratoma. We have studied the differences between gonadal and extra-gonadal malignant teratomas and the effects of chemotherapy in both genders. Methods: The samples of 3799 male and 1832 female patients with malignant teratoma samples, between the ages of 1 and 85+ years, were selected from the years 1973 to 2014. Trends in incidence, estimated prevalence, incidence rates, and frequency were calculated in gonadal and extra-gonadal tumors with age adjustment. The fiveyear observed, expected, and relative survival rates were analyzed to study the prognosis.
The laser tissue welding device is intended for use in patients requiring sealing of the pancreas after partial pancreatectomy, and including those patients who are fully heparinized or have hemodilutional coagulation failure. The hypothesis is that the laser tissue welding device is safe and effective in sealing the pancreas, thereby decreasing the blood loss (operative and post-operative), and pancreatic juice leakage for patients when the Laser Tissue Welding device is used after pancreatic resection.
