2/16. Postirradiation sarcoma: a case report and current review.Irradiation-induced sarcomas are well-known potential late sequelae of radiation therapy. These tumors are very aggressive and often elude early detection and timely intervention, rapidly leading to early demise of afflicted patients. Long-term patient follow-up and a high index of suspicion are crucial for timely intervention. In this report, we present a case of irradiation-induced osteosarcoma involving the mandible. Diagnostic and therapeutic considerations are subsequently discussed.- - - - - - - - - - ranking = 0.4keywords = radiation-induced (Clic here for more details about this article) |
3/16. radiation-induced petrous internal carotid artery aneurysm.Iatrogenic internal carotid artery aneurysm is a rare complication of irradiation. There are few reported cases in the literature. A case of radiation-induced petrous internal carotid artery aneurysm in a patient with nasopharyngeal cancer treated with radiotherapy is reported. The approach to managing such an aneurysm is discussed.- - - - - - - - - - ranking = 0.2keywords = radiation-induced (Clic here for more details about this article) |
4/16. cochlear implantation in postirradiated ears: outcomes and challenges.OBJECTIVES: radiotherapy to head and neck tumors can potentially damage the auditory pathways. This has relevance in cochlear implants and there is a need for clinical studies to confirm the feasibility of cochlear implantation in these patients. methods: The records of all patients who had received cochlear implants at our institution were reviewed in this retrospective study and those who had prior irradiation for head and neck tumors were further studied. Case controls consisted of comparable cochlear implant recipients who did not have prior radiotherapy. RESULTS: Four of 230 patients met the criteria for further study. They had received radiotherapy for nasopharyngeal carcinoma 11 to 28 years ago and the postimplant follow-up period ranged from 9 to 46 months. The implanted ear of each patient had favorable preoperative promontory stimulation results. Postimplant, all patients were satisfied with their hearing outcomes and the improvement in speech discrimination scores was comparable to the controls. These cases also illustrated specific clinical concerns, including 1) radiation-induced endocrine dysfunction was common and, if overlooked, could result in increased anesthetic risks, and 2) irreversible eustachian tube dysfunction led to chronic middle ear problems, which complicated surgery; the use of modified surgical techniques overcame these difficulties. CONCLUSIONS: Deafened postirradiated patients with nasopharyngeal carcinoma were able to achieve good postimplant hearing outcomes comparable to those of nonirradiated patients. Should cochlear implantation be indicated in patients who have had prior radiation to the head and neck, specific preoperative, intraoperative, and postoperative issues have to be addressed.- - - - - - - - - - ranking = 0.2keywords = radiation-induced (Clic here for more details about this article) |
5/16. Treatment of radiation-induced alopecia.radiotherapy is frequently employed in the management of head and neck neoplasia, either as an adjunct to surgery or as the sole treatment modality. Consequently, radiation alopecia--a well-known complication of high-dosage radiotherapy--is seen often. Longer patient survival, especially with earlier discovery of the malignancy and more refined treatment regimens, will provide the surgeon with the opportunity to treat radiation alopecia by means of the punch graft technique of hair transplantation. The technique is substantially similar to that employed in treating male pattern baldness, although the approach to the recipient and donor areas must be modified. A successful case report is documented and a modified approach is highlighted.- - - - - - - - - - ranking = 0.8keywords = radiation-induced (Clic here for more details about this article) |
6/16. hemoptysis as the presenting manifestation of thyroid carcinoma. A case report.An unusual case of a 61-year-old man who had hemoptysis as the major presenting manifestation of radiation-induced thyroid carcinoma is reported. The diagnosis was made by bronchoscopic removal of a polypoid lesion that was a direct extension of tumor through the trachea. bronchoscopy is an effective and reliable means of establishing the diagnosis in this unusual subset of patients with thyroid carcinoma invading the trachea, and should be considered as the first diagnostic procedure in a patient with a thyroid mass and hemoptysis.- - - - - - - - - - ranking = 0.2keywords = radiation-induced (Clic here for more details about this article) |
7/16. radiation-induced sarcoma of the breast in a female adolescent. Case report with histologic and therapeutic considerations.A 14-year-old girl developed a radiation-induced sarcoma of the left breast after successful combined surgical and radiation therapy of a left adrenal carcinoma when she was 9 months old. The breast lesion was histologically described as a stromal sarcoma with fibrosarcomatous and myxosarcomatous areas. The second primary lesion and local recurrence of this was treated with surgery. At each recurrence the tumor became more aggressive both clinically and histologically, and eventually proved fatal.- - - - - - - - - - ranking = 0.2keywords = radiation-induced (Clic here for more details about this article) |
8/16. Postquadrantectomy breast deformities: classification and techniques of surgical correction.The deformity which is encountered following quadrantectomy (or similar procedures such as segmentectomy or partial mastectomy) and radiation therapy is difficult to evaluate objectively, and subjective assessment of the cosmetic outcome is extremely variable. In a group of 54 patients who underwent the procedure between 1979 and 1983, the types of cosmetic changes were evaluated and classified according to morphologic criteria. Four types of deformities and their related etiopathologic factors were identified. Type I is characterized by malposition and distortion of the nipple-areola complex and is mainly due to postoperative fibrosis and scar contracture. In type II deformity, localized tissue insufficiency is observed, which may be due to skin deficiency (type IIa), subcutaneous tissue deficiency (type IIb), or both (type IIab). Type III deformity is characterized by breast retraction and shrinkage and is mainly due to the effects of radiotherapy on residual breast parenchyma. In type IV deformity, severe radiation-induced damage to the skin, nipple-areola complex, and subcutaneous and glandular tissues is present. Surgical correction of each type of deformity is discussed, and examples are reported.- - - - - - - - - - ranking = 0.2keywords = radiation-induced (Clic here for more details about this article) |
9/16. Late irradiation-induced lesions of the lumbosacral plexus.lumbosacral plexus lesions developed in two women 8 and 14 years, respectively, after operation and irradiation for carcinoma of the uterus. In both patients, a left femoral nerve lesion was the presenting sign. The irradiation dose was about 5,000 rad on both sides in patient 1 and 8,400 rad on the affected side in patient 2. Both patients had low-frequency periodic discharges in the EMG.- - - - - - - - - - ranking = 0.8keywords = radiation-induced (Clic here for more details about this article) |
10/16. radiation-induced recurrent intestinal pseudo-obstruction.The syndrome of intestinal pseudo-obstruction is a complex of signs and symptoms of intestinal obstruction without evidence of mechanical obstruction of the intestinal lumen. A patient with radiation-induced intestinal pseudoobstruction is described. The patient is a 74-year old woman with a history of chronic diarrhea, recurrent episodes of crampy abdominal pain, nausea and vomiting since receiving a 13,000 rad radiation dose to the pelvis in 1954. She has been hospitalized on many occasions for symptoms and signs of bowel obstruction. Upper gastrointestinal contrast roentgenograms with small bowel follow-through done during these episodes revealed multiple dilated loops of small bowel with no obstructing lesion. barium enemas revealed no obstructing lesion. Each episode resolved with conservative therapy. Other secondary causes for intestinal pseudo-obstruction were ruled out in our patient. She gave no history of familial gastrointestinal disorders. Although postirradiation motility abnormalities have been demonstrated experimentally this is the first report of radiation induced intestinal pseudo-obstruction.- - - - - - - - - - ranking = 0.2keywords = radiation-induced (Clic here for more details about this article) |
