Chondrosarcoma of the larynx after radiation treatment for vocal cord cancer.

The case of a 57-year-old man with chondrosarcoma of the laryngeal cartilage is presented, occurring 16 years after radiation treatment for squamous cell carcinoma of the right true vocal cord. Chondrosarcoma of the larynx is an uncommon tumor. The location, grade, and time elapsed from initial treatment make it probably that this patient's chondrosarcoma is associated with his prior radiation treatment.

Treatment of sarcomas of the chest wall using intensive combined modality therapy.

As part of two sequential protocols using intensive combined modality treatment in pediatric and adolescent sarcomas, 31 consecutive patients with primary chest wall tumors were treated between November 1977 and March 1986. This group included 13 patients with peripheral neuroepithelioma (Askin's tumor), 11 patients with Ewing's sarcoma, 3 patients with rhabdomyosarcoma, and 4 patients with undifferentiated sarcomas. Following complete work-up, 17 patients presented with localized disease and 14 patients presented with metastases.

Salvage irradiation of oropharyngeal cancers using iridium 192 wire implants: 5-year results of 70 cases.

Between May 1971 and November 1980, 70 patients with recurrent or new oropharyngeal cancers arising in previously irradiated tissues were treated using iridium 192 afterloading techniques. The actuarial local control was 72% at 2 years and 69% at 5 years. Although local control of the tumor was achieved in the majority of these patients, only 10 patients remained alive at 5 years (14%).

Diagnosis of pulmonary nodules in the cancer patient: the role for routine culture and an unusual application of the human tumor colony-forming assay.

Many solid tumors that occur in humans tend to metastasize to the lungs. The etiology of pulmonary nodules in cancer patients, therefore, presents a diagnostic problem that can be resolved only by histologic evaluation or resection. We present two cases of cancer patients with preoperative and intraoperative diagnoses of metastatic lung tumors.

Conservative treatment of breast cancer in Europe: report of the Groupe Européen de Curiethérapie.

These two meetings organised successively to discuss the conservative methods of treatment of breast cancer, made it possible to gather data on a substantial number of patients from an important number of European centers. It is encouraging to note that there is a general consensus among the various European centers concerning the basic principles of treatment and that long years of experience have led to the use of well defined technical protocols which are relatively similar from one center to another. Since serious complications have now become exceptional, we foresee that the conservative treatment of breast cancer will continue to evolve on a technical level as the indications for this approach continue to develop within the overall plan of patient care with the assurance that optimum results may be maintained.
