Background: Keloids are benign fibrous dermal tumors originating from skin injury after surgery, piercing or others wounds. Materials and Methods: Sixty-two patients with keloids were treated postoperatively using orthovoltage irradiation. The total dose delivered was 12 Gy in three consecutive days, 4Gy per fraction. Treatment started 24 h after surgery. The median follow-up was 44.5 months. R...

introduction superficial x-ray therapy is one of the most important treatment methods in radiotherapy especially in the treatment of superficial skin lesions (up to 300 kvp). quality of the x-ray beam that can be expressed by half-value layer (hvl), are important indices for this type of treatment effective energy of photon and homogeneity coefficient (hc). materials and methods the hc of the s...

OBJECTIVES We retrospectively evaluated patients who underwent surgery for parotid gland masses. PATIENTS AND METHODS A total of 50 patients (25 females, 25 males; mean age 48.5 years; range 18 to 76 years) who underwent surgery for parotid gland masses were evaluated with regard to age, sex, preoperative diagnostic methods, histopathologic diagnoses, and surgical techniques. RESULTS Preope...

PURPOSE Surface electronic brachytherapy (EBT) is an alternative radiotherapy solution to external beam electron radiotherapy and high-dose-rate radionuclide-based brachytherapy. In fact, it is also an alternative solution to surgery for a subgroup of patients. The objective of this work is to confirm the clinical efficacy, toxicity and cosmesis of a new EBT system, namely Esteya(®) in the trea...

Primary Hodgkin's lymphoma of the parotid gland is rare. A twenty-one-year-old man presented with a lesion that recurred two years after an excisional biopsy for a parotid gland mass. He underwent superficial parotidectomy. Frozen section examination suggested a diagnosis of Hodgkin's lymphoma. The patient was treated by radiotherapy. A complete recovery was obtained after a 27-month follow-up.

Radiotherapy can convert malignant cells into an in situ anticancer vaccine, but is often inadequate at generating sufficient pro-inflammatory signals to optimally activate innate and adaptive immune responses. Topical imiquimod is a powerful pro-inflammatory agent with clinical activity against superficial skin cancers. These two modalities appear to complement each other, hence achieving loca...

Since 1984, through 8 years, 29 cases of bladder tumor were treated with high dose rate intracavitary radiotherapy. All cases were transitional cell carcinoma in histology and consisted of 12 cases of CIS, 7 of Ta, 3 of T1, 1 of T2 and 6 of T3. At the intracavitary therapy, 3-way catheter made specially for high dose rate intracavitary radiotherapy was inserted into the bladder and the balloon ...

Introduction: Brachytherapy, especially using manually after loaded Iridium-192 and Cobalt-60, can be applied as a sole treatment, as a treatment complementary to surgery, and as a local boost in combination with EBRT. The use of HDR brachytherapy catheters incorporated in removable dental molds allows repeated, highly reproducible, fractionated outpatient brachytherapy of supe...

Introduction Superficial X-ray therapy is one of the most important treatment methods in radiotherapy especially in the treatment of superficial skin lesions (Up to 300 kVp). Quality of the X-ray beam that can be expressed by Half-Value Layer (HVL), are important indices for this type of treatment effective energy of photon and Homogeneity Coefficient (HC).
