Leptomeningeal metastasis (LM) is rarely observed in gynecologic cancers. As gadolinium-enhanced magnetic resonance imaging (Gd-MRI) is highly effective for diagnosing LM, the aim of this study is to describe the clinical behaviors and outcomes of LM patients who were diagnosed by Gd-MRI. After securing institutional review board approvals, we retrospectively reviewed patient records. Eight patients were found to have LM from gynecological malignancies. Primary tumors included three ovarian cancers, one tubal cancer, one peritoneal cancer, two endometrial cancers, and one cervical cancer...

BACKGROUND: Solid tumors, such as hepato-pancreato-biliary cancer, develop tumor hypoxia with tumor growth. Despite advances in surgery, a majority of these patients are in an unresectable condition. At this stage standard cytotoxic chemotherapy regimens are applied with limited success. Novel biological treatment options based on an antiangiogenic mechanism of action neglect other hypoxia mediated mechanisms (e.g. epithelial-mesenchymal transition, Warburg effect, and immunological response) leading to an increased invasiveness with a poor outcome...

BACKGROUND: Inflammatory myofibroblastic tumors (IMTs) are rare sarcomas that can occur at any age. Surgical resection is the primary treatment for patients with localized disease; however, these tumors frequently recur. Less commonly, patients with IMTs develop or present with metastatic disease. There is no standard of care for these patients and traditional cytotoxic therapy is largely ineffective. Most IMTs are associated with oncogenic ALK, ROS1 or PDGFRβ fusions and may benefit from targeted therapy...

BACKGROUND: Malignant peripheral nerve sheath tumor schwannoma (MPNST), also known as malignant schwannoma, is a very rare tumor accounting for only 2% of all sarcomas. The prognosis is relatively poor, with a 5-year survival rate of 46-69%. The treatment of MPNST has not been standardized yet. Mainstay treatment is radical resection. Oncological adjuvant or neoadjuvant treatment has equivocal indications with unclear effects. CASE: The case report presents a 55-year-old patient who showed resistance in the medial-ventral area of the left lower limb...

INTRODUCTION: Nodal categories for malignant pleural mesothelioma (MPM) are derived from the lung cancer staging system and have not been adequately validated. The International Association for the Study of Lung Cancer (IASLC) developed a multinational database to generate evidence-based recommendations to inform the 8(th) edition of the tumor, node metastasis classification of MPM. METHODS: Data from 29 centers were entered prospectively (n=1,566) or by transfer of retrospective data (n=1,953)...

INTRODUCTION: The M component and TNM stage groupings for malignant pleural mesothelioma (MPM) have been empirical. The International Association for the Study of Lung Cancer developed a multinational database to propose evidence-based revisions for the eighth edition of the TNM classification of MPM. METHODS: Data from 29 centers were submitted either electronically or by transfer of existing institutional databases. The M component as it currently stands was validated by confirming sufficient discrimination (by Kaplan-Meier analysis) with respect to overall survival (OS) between the clinical M0 (cM0) and cM1 categories...

Cone-beam computed tomography CBCT systems are used in radiation therapy for patient alignment and positioning. The CBCT imaging procedure for patient setup adds substantial radiation dose to patient's normal tissue. This study pre-sents a complete procedure for the CBCT dosimetry using the InLight optically-stimulated-luminescence (OSL) nanoDots. We report five dose parameters: the mean slice dose (DMSD); the cone beam dose index (CBDIW); the mean volume dose (DMVD); point-dose profile, D(FOV); and the off-field Dose...

For nearly 40 years, there was no generally accepted staging system for malignant pleural mesothelioma (MPM). In 1994, members of the International Mesothelioma Interest Group (IMIG), in collaboration with the International Association for the Study of Lung Cancer (IASLC), proposed a tumor, node and metastasis (TNM) staging system based on analyses of outcomes in retrospective surgical series and small clinical trials. Subsequently accepted by the American Joint Commission on Cancer (AJCC) and the Union for International Cancer Control (UICC) for the 6(th) editions of their staging manuals, this system has since been the international staging standard...
