A rare malignant periurethral carcinosarcoma with aggressive behavior: A case treated with a multimodal treatment approach.

Urol Case Rep 2021 Sep 29;38:101699. Epub 2021 Apr 29.

Department of Urology, Chungnam National University Sejong Hospital, Chungnam National University, Sejong, South Korea.

Carcinosarcoma is an aggressive tumor that can develop in any organ but is rarely observed in the urinary tract. Given the radioresistant nature of carcinosarcoma and the rapidly regrowing tumor after primary surgery, carcinosarcomas that developed in the body showed poor outcomes regardless of aggressive management. However, the specific optimal treatment for periurethral carcinosarcoma remains unknown. Read More

Successful treatment of non-midline primary malignant germ cell tumors with yolk sac components in neonates: report of 2 cases.

J Neurosurg Pediatr 2020 Oct 30:1-5. Epub 2020 Oct 30.

3Division of Neurosurgery, Department of Pediatric Surgery, Montreal Children's Hospital, McGill University Health Centre, Montreal.

Here, the authors present 2 cases of nongerminomatous germ cell tumor (NGGCT): a neonate with a mixed malignant germ cell tumor, 5% yolk sac tumor (YST) and 95% immature teratoma components, originating from the right mesial temporal lobe; and a 2-month-old infant with a pure YST originating from the left middle cranial fossa. These tumors with yolk sac components, which are thought to have a poor prognosis, were successfully treated with complete tumor resection alone and subtotal tumor resection with chemotherapy, respectively. Event-free survival exceeds 5 years for each patient even though neither received radiotherapy. Read More

Late simultaneous carcinomatous meningitis, temporal bone infiltrating macro-metastasis and disseminated multi-organ micro-metastases presenting with mono-symptomatic vertigo - a clinico-pathological case reporT.

Ideggyogy Sz 2020 Sep;73(9-10):354-360

Department of Otorhinolaryngology and Head-Neck Surgery, University of Szeged, Szeged.

LINC00470 promotes tumour proliferation and invasion, and attenuates chemosensitivity through the LINC00470/miR-134/Myc/ABCC1 axis in glioma.

J Cell Mol Med 2020 10 11;24(20):12094-12106. Epub 2020 Sep 11.

Department of Neurosurgery, Xiangya Hospital, Central-South University, Changsha, China.

Glioma is the most common primary malignant tumour in the brain; temozolomide (TMZ) is the most prevalent chemotherapeutic drug currently used to combat this cancer. We reported previously that the long intergenic non-protein coding RNA 470 (LINC00470) is a novel prognostic biomarker for glioma and promotes the tumour growth in an intracranial transplantation mouse model. However, the effects of LINC00470 on glioma cell proliferation, invasion and TMZ chemosensitivity, as well as its molecular mechanism, remain unclear. Read More

Department of Head and Neck Surgical Oncology, Memorial Sloan Kettering Cancer Center, New York, New York, USA,

Squamous cell carcinoma (SCC) is one of the most common malignant neoplasms involving the anterior skull base, resulting from local invasion from an adjacent anatomical region. The primary sites of origin are most frequently the nasal cavity and paranasal sinuses, and less often the skin and orbit. Treatment strategies for these tumors have evolved, although management remains challenging due to the proximity to critical structures and their location at the intracranial-extracranial interface.

Endocrinol Diabetes Metab Case Rep 2020 Jul 5;2020. Epub 2020 Jul 5.

Department of Endocrinology and Diabetes, Blacktown Hospital, Sydney, Australia.

Summary: Cushing's disease is a rare disorder characterised by excessive cortisol production as a consequence of a corticotroph pituitary tumour. While the primary treatment is surgical resection, post-operative radiation therapy may be used in cases of ongoing inadequate hormonal control or residual or progressive structural disease. Despite improved outcomes, radiotherapy for pituitary tumours is associated with hypopituitarism, visual deficits and, rarely, secondary malignancies. Read More
