superficial siderosis (ss) is a rare disease which affects people in all ages and both sexes, but three times more in men. pathological etiology is deposition of hemosiderin (a product of the breakdown of blood) in leptomeninges, subpial layer, ependymal surface and other parts of central nervous system (cns) and typically leads to neurological dysfunction and progressive irreversible signs and...
OBJECTIVE This observational study was to identify risk factors for vulvar cancer recurrence. MATERIALS AND METHODS In the study 107 patients with primary vulvar cancer were analyzed. Surgical treatment consisted of radical excision of the primary tumor in combination with unilateral or bilateral superficial and deep inguinofemoral lymphadenectomy through separate incisions. Patients with dee...
The purpose of this study was to determine the outcomes and optimal practice patterns of definitive radiotherapy for primary vaginal cancer. Between 1993 and 2012, 49 patients were treated with definitive radiotherapy for primary vaginal cancer in three hospitals. Of these, 15 patients (31%) had clinically positive regional lymph node metastasis. A total of 34 patients (70%) received external b...
We describe the case of a 71-year-old Caucasian female with primary disseminated non-small cell cancer of the lung, presented for palliative radiotherapy of metastatic spread to the 9th and 11th thoracic vertebrae without intramedullary growth. Palliative radiotherapy with daily fractions of 3 Gy and a cumulative dose of 36 Gy to thoracic vertebrae 8-12 was performed. The patient received conco...
BACKGROUND Keloid therapy remains a great challenge for plastic surgeons, especially when the defect cannot be closed primarily, necessitating tissue transplantation. Here, we introduce a new treatment modality, called the sandwich therapy, for presternal keloids; the sandwich therapy incorporates preradiotherapy, superficial circumflex iliac artery perforator (SCIP) flap transplantation, and p...
The skin represented the dose-limiting organ in radiotherapy over long periods of time. In the first third of the 20th century, radiotherapy was associated with deposition of significant radiation doses in the superficial compartments of the skin. Therefore, all major radiobiological principles, such as effects of fractionation on radiation sensitivity or volume/area effects, were initially bas...
PURPOSE To evaluate the therapeutic results and rate of organ preservation in patients with stage III or IV oral cancer treated with retrograde superselective intra-arterial chemotherapy and daily concurrent radiotherapy. MATERIALS AND METHODS One hundred and twelve patients with stage III and IV oral squamous cell carcinoma underwent intra-arterial chemoradiotherapy. Catheterization from the...
BACKGROUND Superficial esophageal cancer (SEC) is defined as esophageal cancer limited to the submucosal layers, including mucosal cancer and submucosal cancer, and is squamous cell carcinoma in most patients. In 2000, the Japanese Society of Therapeutic Radiology and Oncology (JASTRO) Study Group for SEC published a consensus guideline of standard radiotherapy methods. In this study, the inter...
PURPOSE We retrospectively reviewed the results of radiotherapy for localized ocular adnexal MALT lymphoma (OAML) to investigate the risk factors of cataract. METHODS Sixty-seven patients with stage IE OAML treated with radiotherapy at Seoul St. Mary's Hospital from 2001 to 2016 were included. Median treatment dose was 30 Gy. Lens protection was done in 52 (76%) patients. Radiation therapy (R...
Tumor control, thermal enhancement, and therapeutic effect have been evaluated in a series of studies on 77 patients with a total of 163 multiple superficial lesions by using different protocols of combined radiotherapy and local external hyperthermia. Local tumor control and recurrence rate were constantly better in lesions treated with combined treatment in comparison with those treated with ...
