Interest of Preoperative Arteriography to Identify the Adamkiewicz Artery Before Surgery for Basi-thoracic Neuroblastic Tumors
Neuroblastic tumors (NBTs) develop from neural crest cells that give rise to the sympathetic nervous system. They include neuroblastomas, ganglioneuroblastomas, and ganglioneuromas. They represent approximately 10% of solid tumors in children under 15 years of age. In 15 to 20% of cases, NBTs are located in the thoracic region. These paravertebral tumors have an extracanal component and some also have an intraspinal component (dumbbell tumors) that can cause spinal cord compression. Surgery for these tumors also exposes the patient to neurological complications. In the thorax, the basi-thoracic location (T9-T12) may be particularly at risk due to the presence of the artery of...

Interferon-α1b Combined With Toripalimab and Anlotinib Hydrochloride in Advanced Unresectable Melanoma
The purpose of this study is to evaluate the efficacy and safety of recombinant human interferon-α1b (IFN-α1b) combined with toripalimab and anlotinib hydrochloride in patients with unresectable advanced melanoma. This study consists of 2 phases( Ib / II). Phase Ib will determine the recommended phase Ⅱ dose for anlotinib hydrochloride. Phase II will evaluate the efficacy and safety of the triple combination regimens.

Intraoperative Fluorescence-Guided Aspirate Tissue Monitoring of 5-ALA During Brain Tumor Surgery
Gliomas are tumors that occur in all ages; they include the most common malign primary central nervous system tumors in developed countries. Gliomas are often aggressive, and their recommended treatment is surgical resection and chemoradiation. Complete tumor removal is challenging because of diffuse cell growth and the proximity of functionally critical tissues. The current golden standard for intraoperative glioma detection is fluorescence-guided surgery (FGS) using 5-ALA. In 5-ALA FGS the drug-induced fluorescence helps to visually detect tumor cells, which improves resection rates and delays tumor progression. Tumor cells are often left unnoticed because of visual obstacles or...

Intraoperative Fluorescent Staining Combined With Microsurgery for Gliomas
Through the modified formulation of sodium fluorescein and methylene blue, the surface of the suspected cut edge of the patient's glioma was stained intraoperatively, and the surgical microscope image acquisition and processing system was used to determine whether the cut edge of the surgically resected tissue was positive or not. And combined with the existing multimodal surgical techniques (imaging, electrophysiology, neuronavigation and other equipment), the glioma is precisely resected.

Intrathecal Pemetrexed for Leptomeningeal Metastasis From Lung Adenocarcinoma That Progressed After Osimertinib.
Pemetrexed is one of the first-line chemotherapeutic agents for non-squamous non-small cell lung cancer (NSCLC). Since 2017, intrathecal pemetrexed has shown good efficacy for patients with leptomeningeal metastases from NSCLC. It has been recommended as the preferred drug for intrathecal chemotherapy by the Chinese Society of Clinical Oncology (CSCO) guidelines. Tyrosine kinase inhibitors (TKIs) play a promising role in treating non-small cell lung cancer patients with epidermal growth factor receptor (EGFR) mutations. An international multi-center clinical study published in 2019 confirmed that double dose of osimertinib showed significant improvement in leptomeningeal...

Intrathecal Pemetrexed for Leptomeningeal Metastasis in EGFR-Mutant NSCLC
Leptomeningeal metastasis (LM) is a complication of advanced non-small cell lung cancer (NSCLC). The incidence of LM in NSCLC patients is around 3-5 %, reaching 9.4 % of those with an epidermal growth factor receptor (EGFR) mutation. Generally, the efficacy of systemic treatment for LM is limited due to the blood-brain barrier. Osimertinib has a high central nervous system penetration rate, making it the preferred first-line treatment for EGFR-mutant NSCLC. Previous studies indicated that osimertinib had shown promising efficacy in pretreated patients harboring EGFR mutations and LM. However, intracranial disease progression eventually develops, and the prognosis of patients...

Investigating Participation Patterns Among Stage IV Melanoma Patients
Clinical trials, specifically focused on stage IV melanoma, are crucial in assessing the safety and efficacy of new treatments for this disease. These trials serve as fundamental instruments in determining whether emerging medications outperform standard therapies, providing compelling evidence to support wider implementation. The main goal is to thoroughly scrutinize trial completion rates and voluntary withdrawals among this particular group of patients.

Investigation of the Performance of the Medical Device Dermalyser in Determining Melanoma Thickness Based on Dermoscopy Images
In Sweden, approximately 9,000 Swedes are affected by melanoma annually, and each year, 500 individuals die from metastatic melanoma. The prognosis for melanoma primarily depends on the thickness of the tumor at diagnosis. Melanomas that only grow in the epidermis and have not yet grown into the dermis are called melanoma in situ or pre-melanoma. These melanomas lack the potential to spread in the body. Melanomas that grow into the dermis, on the other hand, are called invasive or malignant melanomas. Invasive melanomas have the potential to spread in the body. To improve melanoma diagnostics, a dermatoscope is used. A dermatoscope is a type of magnifying glass equipped with a...

In Vitro Models From Pediatric Brain Tumors
Tumors of the Central Nervous System (CNS) represent the leading cause of cancer-related deaths in children. Current treatment options are not curative for most malignant histologies, and intense preclinical and clinical research are necessary to develop more effective therapeutic interventions against these tumors, most of which meet the FDA definition for orphan diseases. The majority of malignant CNS tumors in children and adolescents belong to two broad histologic tumor entities: those of glial origin, such as high-grade glioma (HGG)and ependymoma (EPN), and those of neuronal origin, also identified as embryonal tumors, that include medulloblastoma and AT/RT(1). Over the...

Irinotecan Liposomes for the Treatment of Neuroendocrine Carcinoma
This study is a real-world clinical study. It is expected to include 20 patients with first-line and second-line gastrointestinal pancreatic neuroendocrine carcinoma who will be treated with irinotecan liposomes combined with cisplatin or carboplatin regimen. The research unit is the First Affiliated Hospital of Xi'an Jiaotong University. The study includes a screening period (within 28 days), a treatment period (planned for 6 cycles), and a follow-up period (safety follow-up and PFS follow-up). The subjects signed an informed consent form and underwent baseline examination during the screening period. Patients who met the inclusion and exclusion criteria entered the treatment...
