1/341. Customized mold brachytherapy for oral carcinomas through use of high-dose-rate remote afterloading apparatus.

    OBJECTIVE: The aim of this study was to investigate the role of the combined use of customized molds and recently available remote afterloading brachytherapy apparatus with more flexible catheters in the treatment of superficial oral carcinomas. STUDY DESIGN: Four patients with oral squamous cell carcinoma who were treated through use of this combined technique were analyzed retrospectively. The molds were made from transparent acrylic resin through use of a dental technique. The combined approach was applied as a boost therapy after external irradiation. RESULTS: The 4 patients had had no recurrence of tumor or radiation injury by the end of the follow-up period. CONCLUSIONS: The combined technique could be an excellent method of treating superficial carcinomas of the oral cavity.

2/341. radiation-induced esophageal carcinoma 30 years after mediastinal irradiation: case report and review of the literature.

    A 54-year-old man who had been irradiated in 1964 for cervical involvement by Hodgkin's disease was admitted in December 1994 to our clinic with strong complaints of dysphagia. The reason was a moderately differentiated squamous cell carcinoma of the proximal esophagus in the previously irradiated region. The patient had no risk factors (abuse of nicotine or alcohol) for the developement of esophageal carcinoma. A reirradiation was performed, but the disease progressed locally and two weeks after the beginning of the therapy the patient developed two tracheoesophagocutaneous fistulae. The radiation therapy was discontinued and the tumor stenosis was bridged by a tube closing the fistulae. A retrospective dose analysis to evaluate the applied doses will be performed. Furthermore, an overview of 66 cases of the literature with radiation-induced esophageal carcinoma analysed concerning applied dose and latent interval will be given. In conclusion the reported case fits the criteria for radiation-induced malignancies (Chudecki Br J Radiol 1972;45:303-4) known from literature: (1) a history of previous irradiation, (2) a cancer occurring within the irradiated area, (3) gross tissue damage due to an excessive dose of radiation, and (4) a long latent interval between irradiation and development of cancer. Esophageal carcinomas belong to the rare secondary malignancies after the therapeutic use of ionizing radiation. Nevertheless in patients with dysphagia they should be suspected as a differential diagnosis even many years after mediastinal irradiation. The treatment of these tumors is very difficult and is associated with a poor prognosis.

3/341. Vascular transformation of sinuses in bilateral cervical lymph nodes.

    BACKGROUND: Vascular transformation of sinuses (VTS) in lymph node has been infrequently reported. We present a case of incidental VTS in bilateral cervical nodes discovered at the time of operation for tongue cancer. methods: Standard histopathologic review was undertaken. RESULTS: In this case, a spectrum of varied vasoformative patterns involving lymph nodes in either a pan-nodal or localized fashion were identified. The hilum was occupied by smooth muscle proliferation and adipose tissue. Two nodes also displayed similar features of angiolipomatous hamartoma. No metastatic carcinoma was found in lymph nodes with VTS. CONCLUSIONS: This case suggests that lymphovenous congestion and distention represented the major cause through which VTS developed.

4/341. Mediastinal lymph node involvement as the initial manifestation of occult thyroid cancer in the surgical treatment of lung cancer: report of a case.

    A 63-year-old man was referred to our institute for the treatment of squamous cell carcinoma of the upper lobe of his right lung. A right upper lobectomy of the lung was performed with a mediastinal lymph node dissection. The postoperative pathological examination of the dissected specimens revealed one of the superior mediastinal lymph nodes to be morbid with micrometastasis of occult thyroid cancer, while no node involvement was seen due to lung cancer. A right lobectomy of the thyroid gland with a modified radical neck dissection was done 4 years later after the confirmation of the absence of any recurrent sign of lung cancer. In the resected specimen, papillary thyroid microcarcinoma was observed with several intraglandular metastases and right regional lymph node involvement. Eight months later, a new primary lung cancer developed in the left lung, and a left upper lobectomy of the lung with a mediastinal lymph node dissection was performed. At that time, the absence of mediastinal lymph node metastasis from lung cancer or thyroid cancer was confirmed. Mediastinal lymph node involvement as the initial manifestation of occult thyroid cancer in surgical treatment for lung cancer is rare, but it is important to be aware of the possibility of incidentally detecting occult thyroid cancer in surgical dissections in this area for lung cancer. The appropriate surgical treatment should be determined while carefully considering the prognosis of the lung cancer as well as that of any coexisting malignancy.

5/341. Surgical management of acquired laryngopharyngeal fistulae.

    Pathological communication between the food and air passages in the neck region due to malignant disease is known. However, such a pathology arising as a result of a non malignant process is relatively uncommon, and only a handful of reports exists in the literature. The authors describe and discuss the management of two patients with laryngopharyngeal fistula of nonmalignant etiology.

6/341. Gastric tube-to-tracheal fistula closed with a latissimus dorsi myocutaneous flap.

    A gastric tube-to-airway fistula is a very rare complication after esophageal reconstruction. A patient with a gastric tube-to-tracheal fistula that developed more than 9 years after surgery for cancer of the cervical esophagus was treated with transposition of a pedicled latissimus dorsi myocutaneous flap. Careful perioperative respiratory management helped save the patient's life.

7/341. Primary intraosseous carcinoma of the mandible with probable origin from reduced enamel epithelium.

    This report describes a case of primary intraosseous carcinoma (PIOC) arising de novo in the mandible. The patient was a 74-year-old woman and an early PIOC was found incidentally during histopathological examination of the pericoronal tissue obtained at extraction of a deeply impacted third molar. The curetted soft tissues consisted of a microinvasive, keratinizing squamous cell carcinoma with scattered foci of carcinoma cells showing calcification; stromal osseous metaplasia was also observed. After additional treatment, the patient has remained free of disease for 2 years. Since the tumor was completely enclosed in the bone, the only identifiable source of the present PIOC is the reduced enamel epithelium. Despite its rarity, this case emphasizes the importance of careful histologic examination of all apparently innocuous dental follicles that are removed surgically.

9/341. High-dose-rate mold brachytherapy of early gingival carcinoma: a clinical report.

    Two elderly edentulous patients with the diagnosis of early stage cancer of the upper gingiva were treated by customized dental mold brachytherapy. Locoregional tumor control was achieved in both patients. One patient is alive without any evidence of disease 36 months after treatment, the other patient died of distant metastasis shortly after brachytherapy. brachytherapy, being easy to apply with short treatment time and good acute tolerance, is a good choice and effective modality for the management of early stage gingival cancer, particularly in elderly patients.

10/341. Various extrahepatic manifestations caused by hepatitis c virus infection.

    It has been reported that hepatitis c virus (HCV) causes not only liver disease but also disorders of other organs and tissues. Previously, many HCV-related extrahepatic manifestations have been reported. In this study, we report 2 patients in whom tongue cancer was detected during the treatment of HCV-related liver disease. In one patient, tongue cancer was detected during the treatment of HCV-related liver cirrhosis, and articular rheumatism developed thereafter. The duration of HCV-related liver disease was 10 years. In the other patient, tongue cancer was detected during the treatment of HCV-related hepatocellular carcinoma. This patient had a past history of thyroid disease. The duration of HCV-related liver disease was 6 years. In these patients, the possibility that several conditions incidentally and concurrently developed cannot be denied. However, the conditions described above may be regarded as HCV-related extra-hepatic manifestations. In patients with HCV infection, it is important to examine conditions in organs other than the liver. Careful follow-up is needed.
