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...
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.
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...
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.
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...
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...
This study aimed to evaluate the efficacy and safety of intrathecal pemetrexed for SCLC patients with refractory brain metastases or leptomeningeal metastasis.
The primary hypothesis being tested in this trial is that ischemic stroke patients with active cancer will have improved clinical outcomes when given intravenous thrombolysis compared to standard care.
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.
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...
