Proposal for Modification of Cahan's Criteria Utilizing Molecular Genetic Analyses for Cases without Baseline Histopathology: A Unique Method Applicable to Primary Radiosurgery.

J Neurol Surg B Skull Base 2019 Feb 31;80(1):10-17. Epub 2018 May 31.

Department of Otolaryngology-Head and Neck Surgery, Mayo Clinic, Rochester, Minnesota, United States.

 Cahan's criteria have been utilized since 1948 to establish causality between prior radiation treatment and the development of secondary malignancy. One major criterion specifies that histological and radiographic evidence collected before and after radiation treatment must confirm separate tumor types; however, pretreatment biopsy is rarely obtained prior to radiosurgery for vestibular schwannoma and many other skull base and cranial lesions. Therefore, in these cases Cahan's criteria cannot be validly applied. Read More

Prosthetic rehabilitation involving the use of implants following a fibula free flap reconstruction in the treatment of Osteosarcoma of the maxilla: a case report.

Clin Ter 2017 Nov-Dec;168(6):e392-e396

M.D., D.D.S., Università degli studi di Roma La Sapienza.

Introduction: Osteosarcoma is an aggressive primary bone tumor composed of connective tissue cells directly producing osteoid and bone. Prosthetic rehabilitations in post-oncological patients after bone reconstruction are not substantially different than those of patients affected by severe atrophy of upper or lower jaw after bone reconstruction. The treatment for patients with a malignant neoplasia of the oral cavity requires multidisciplinary approach by a team of different specialists that follow the patient through the phases of diagnosis, therapy and oral rehabilitation.

J Coll Physicians Surg Pak 2017 Sep;27(9):S117-S119

Department of Oral Medicine and Radiology, Government Dental College, Jaipur, India.

Osteosarcoma is a rare primary malignant bone tumor with considerable variations not only in clinical and histologic appearance, but also in the course and prognosis of the disease. It mainly occurs in the metaphyseal region of long bones. Jaw osteosarcomas are relatively rare as compared to those occurring in long bones and share similar histopathologic features, but biologically behave in a different manner. Read More

Detection of Non-FDG-Avid Residual Sinonasal Malignant Melanoma in the Skull Base With 11C-Choline PET and Contrast-Enhanced MRI.

Clin Nucl Med 2017 Nov;42(11):885-886

From the *Department of Nuclear Medicine, and †Hubei Province Key Laboratory of Molecular Imaging, Union Hospital, Tongji Medical College, Huazhong University of Science and Technology, Wuhan, Hubei Province, China.

Primary sinonasal melanoma is a rare disease. We present a case of melanoma in sinuses without abnormal F-FDG activity anywhere in the scanned portion of the body. In further assessment, C-choline PET/CT revealed high activity in the paranasal sinuses, skull base, and adjacent brain, in agreement with the high signal on contrast-enhanced T1-weighted MRI scan, which suggested the residual tumor.

Understanding the potentiality of accelerator based-boron neutron capture therapy for osteosarcoma: dosimetry assessment based on the reported clinical experience.

Radiat Oncol 2017 Aug 15;12(1):130. Epub 2017 Aug 15.

National Atomic Energy Commission (CNEA), Av. General Paz, 1499, Buenos Aires, Argentina.

Background: Osteosarcoma is the most frequent primary malignant bone tumour, and its incidence is higher in children and adolescents, for whom it represents more than 10% of solid cancers. Despite the introduction of adjuvant and neo-adjuvant chemotherapy that markedly increased the success rate in the treatment, aggressive surgery is still needed and a considerable percentage of patients do not survive due to recurrences or early metastases. Boron Neutron Capture Therapy (BNCT), an experimental radiotherapy, was investigated as a treatment that could allow a less aggressive surgery by killing infiltrated tumour cells in the surrounding healthy tissues.

Esthetically Favorable Surgical Alternative for the Removal of Sinonasal Malignant Tumors-The Modified Facial Degloving Technique.

J Oral Maxillofac Surg 2017 Oct 29;75(10):2272.e1-2272.e10. Epub 2017 Jun 29.

Professor and Head of Department, Department of Otorhinolaryngology, Head and Neck Surgery, University of Szeged, Szeged, Hungary.

Purpose: The widely used external approach (Weber-Fergusson incision) for the removal of maxillary ethmoid tumors leaves stigmatizing scars and deformities on the patient's face. As an alternative technique, the scarless facial degloving approach was first described in the 1970s; since then, several modifications have been developed.

Patients And Methods: The authors have been using a modified facial degloving technique for 7 years to remove maxillary ethmoid tumors. Read More
