Definitive radiotherapy for T1 and T2 squamous cell carcinoma of the tonsil.

Background: To assess whether survival or local control of early squamous cell carcinoma of the tonsil has been compromised by a moderate-dose approach.

Methods: Between 1970 and 1989, 185 patients with SCCa of the tonsil were seen at our institution. Fifty-three patients with T1 (30) and T2 (23) lesions treated with definitive radiotherapy were reviewed.

Preoperative regional therapy for extremity sarcoma. A tricenter update.

Background: Preoperative radiation with sensitizing doxorubicin has been popularized in the treatment of high grade sarcoma of the extremity. A multiinstitutional experience with this protocol that was initiated by the Southeastern Cancer Study Group in 1984 and maintained in three institutions was updated by the authors.

Methods: Patients with biopsied sarcoma had intraarterial infusion with doxorubicin hydrochloride (Adriamycin) 30 mg/24 hrs x 3 days and were allocated by the institution to receive radiation 30-35 Gy in 10 fractions or 46 Gy in 23-25 fractions followed by resection.

Craniofacial resection at the University of Virginia (1976-1992): survival analysis.

Background: The purpose of this study is to evaluate the survival of patients treated at the University of Virginia Health Sciences Center with an anterior craniofacial resection in conjunction with radiotherapy and/or chemotherapy for malignancies of the superior sinonasal cavity. In addition, the impact of aggressive salvage therapy for patients with recurrent disease is considered.

Methods: Between June 1976 and December 1992, a total of 45 patients underwent a craniofacial resection by the Departments of Otolaryngology-Head and Neck Surgery and Neurological Surgery at the University of Virginia.

Esthesioneuroblastoma. Long-term outcome and patterns of failure--the University of Virginia experience.

Background: Esthesioneuroblastoma is a rare tumor arising from olfactory epithelium. This retrospective review analyzed the patterns of failure and long term outcome of patients with esthesioneuroblastoma evaluated at a single institution.

Methods: Forty patients with esthesioneuroblastoma were evaluated at the University of Virginia, with a median follow-up of 130 months.

Glomus jugulare tumors. Long-term control by radiation therapy.

The records of 49 patients with glomus jugulare tumor seen at the University of Virginia from 1932 to 1985 were retrospectively reviewed with the objective of assessing long-term results of treatment. Follow-up ranged from 5 to 31 years, with a minimum of 10 years in 36 patients (73%). According to McCabe's classification, 17 patients (35%) were Group I, 11 patients (22%) were Group II, and 21 patients (43%) were Group III.

Phase I/II trial of superselective arterial 5-FU infusion with concomitant external beam radiation for patients with either anaplastic astrocytoma or glioblastoma multiforme.

From August 1987 through September 1989, 25 patients with either anaplastic astrocytoma (8 patients) or glioblastoma multiforme (17 patients) were entered into a Phase I trial of combined intra-arterial 5-fluorouracil (5-FU) and external beam radiation therapy. The intra-arterial 5-FU was given in a superselective, supraopthalmic fashion, in escalating doses from 200 mg to 600 mg on a weekly basis during the radiotherapy. Each patient received from 1-4 courses of 5-FU.

The influence of extent of neck treatment upon control of cervical lymphadenopathy in cancers of the oral tongue.

This is a retrospective analysis of the management of the neck in 84 patients with squamous cell carcinoma of the oral tongue treated with curative intent between 1968 and 1985. Patients with a clinically negative neck were treated to the neck only if the patient was thought to have a reasonable probability of occult neck metastases. This policy resulted in a 3-year adjusted neck control rate for N0 patients treated with limited (no, bilateral-partial, or ipsilateral) neck therapy of 38% compared with 95% for patients treated with bilateral, whole neck irradiation (p less than .

The role of definitive radiation therapy in squamous cell carcinoma of the oral tongue.

Between 1968 and 1985, 114 patients with squamous cell carcinoma of the tongue were evaluated in the Department of Radiation Oncology at the University of Virginia (Charlottesville, VA); of these, 86 received treatment with curative intent. The majority were treated with radiation therapy alone, whereas the remainder were treated with radiation therapy with preoperative or postoperative surgery. There were 17 T1 primary malignancies, 40 T2, 27 T3, and 2 T4.

Curative radiotherapy in non-small cell carcinoma of the lung.

Recent reports suggest radiotherapy administered to the 5000-6000 cGy level can result in significant long-term survival in non-small cell carcinoma of the lung. This is particularly true for many cases that are technically operable but for medical or other reasons thoracotomy cannot be performed. Such patients drawn from Southern Appalachia where the principal industry is coal mining are the subject of this report.

A phase I-II trial of multimodality management of bulky gynecologic malignancy. Combined chemoradiosensitization and radiotherapy.

Between December 1983 and December 1987, there were 44 patients with bulky, nonresectable squamous cell carcinomas of the gynecologic tract (cervix, 36; vagina, eight) who were treated with concomitant chemotherapy and radiotherapy. Chemotherapy consisted of 5-fluorouracil (5-FU) 1g/m2 given by continuous intravenous infusion on days 1 through 4 and mitomycin C 10 mg/m2 given intravenously on day 1. External-beam irradiation was started on day 1 with a total calculated dose of 5000 cGy in 25 fractions employed.

Primary malignant extragonadal germ cell tumors. An analysis of the effect of the effect of radiotherapy.

A retrospective analysis was performed on all patients diagnosed with biopsy-proven extragonadal germ cell tumors at the University of Virginia (Charlottesville, VA), The Medical University of South Carolina (Charleston, SC), the Bethesda Naval Hospital (Bethesda, MD), and The Medical College of Virginia (Richmond, VA) for the time period of January 1965 to December 1984. A total of 54 patients were treated with the initial sites of presentation observed: mediastinum, 26; central nervous system, 14; retroperitoneum, eight; and sacrococcygeal region, six. Megavoltage irradiation was used in 44 patients with a dose range of 2400 to 5580 cGy (mean, 4213 cGy).

Early glottic carcinoma: patterns and predictors of relapse after definitive radiotherapy.

Although definitive radiotherapy in the management of early glottic carcinomas continues to offer excellent control, a small proportion of patients will have relapse. Between January 1972 and December 1984, 148 patients with squamous cell carcinoma of the glottis (stage I in 95 patients and stage II in 53 patients) had definitive radiotherapy at the University of Virginia Medical Center. We retrospectively analyzed patient data in an attempt to identify patients at risk for relapse and the patterns of failure.

The influence of the surgical wound on local tumor recurrence.

Failure of a primary surgical treatment for cancer is often caused by recurrence of the tumor at the surgical site. The KHT mouse tumor system recapitulates this experience and provides a useful model to test strategies for reducing the incidence of local recurrence after surgical excision. There was an 82% local recurrence of the KHT tumor after surgery.

Minor salivary gland tumors: the role of radiotherapy.

Previous analyses of minor salivary gland tumors (MSGTs) have not clearly established the role of radiotherapy in their treatment. The following is a retrospective review of 44 patients treated from 1956 to 1984 with MSGT of the maxillary sinus (15 of 44), nasal cavity/ethmoid complex (six of 44), or hard palate (23 of 44). Histological findings included adenocarcinoma (18), adenoid cystic (17), high-grade mucoepidermoid (six), and mixed malignant (three).

Definitive radiotherapy in the management of stage I and II carcinomas of the glottis.

Definitive radiotherapy for early glottic carcinoma continues to offer excellent control and the advantage of voice preservation. In the 13 years from January 1972 through December 1984, there were 187 patients diagnosed with squamous cell carcinoma of the glottis at the University of Virginia Medical Center. One hundred forty-eight patients were treated with definitive radiotherapy as the initial management.

Partial laryngectomy and radiotherapy for supraglottic cancer: a conservative approach.

This is a retrospective study of 33 patients with supraglottic cancer treated with partial laryngectomy and moderate-dose radiotherapy at the University of Virginia from 1967 through 1986. All patients had a 2-year minimum follow-up. Ten patients received preoperative radiotherapy, and 23, postoperative radiotherapy.

Concomitant 5-fluorouracil, mitomycin-C, and radiotherapy for advanced gynecologic malignancies.

Advanced gynecologic neoplasms continue to pose major therapeutic problems; 22,500 deaths were estimated for 1987. Between December 1983 and October 1985, there were 25 patients evaluated at our institution who on joint evaluation by the radiation oncologist and gynecologic oncologists were found to have extensive disease not amenable to standard therapy. Patients were to be treated by a combined modality approach with Mitomycin-C and 5-Fluorouracil given concomitantly with radiotherapy.

Whole abdominal radiotherapy following cytoreductive surgery and chemotherapy in ovarian carcinoma.

Persistent or recurrent disease following surgery and chemotherapy in ovarian carcinoma remains a major therapeutic dilemma. Between January 1980 and December 1985, there were 26 patients who had previously undergone cytoreductive surgery and chemotherapy and were treated with external beam radiotherapy. Twenty-one of these patients had been treated with platinum-adriamycin-cytoxan (PAC) regimen and 5 were treated with other combinations.

The effect of hyperthermia on radiation-induced carcinogenesis.

Ten groups of mice were exposed to either a single (30 Gy) or multiple (six fractions of 6 Gy) X-ray doses to the leg. Eight of these groups had the irradiated leg made hyperthermic for 45 min immediately following the X irradiation to temperatures of 37 to 43 degrees C. Eight control groups had their legs made hyperthermic with a single exposure or six exposures to heat as the only treatment.

Esthesioneuroblastoma: a comparison of two treatment eras.

This paper is a retrospective review of 30 patients with esthesioneuroblastoma, an uncommon malignancy of the upper nasal cavity, treated at a single institution from 1959 through 1986. Over the period of study, there has been a gradual evolution of treatment policy and technique with the introduction of craniofacial resections and complex field megavoltage radiation, as well as for Stage C disease, the addition of chemotherapy to radiotherapy and surgery. The 25 patients with a 2 year minimum follow-up are divided into 2 groups depending upon treatment era to determine the impact of modern aggressive therapy upon treatment results.

Results of the radiotherapeutic management of carcinoma of the cervix with emphasis on the influence of histologic classification.

The histology of 365 of 396 patients (92%) treated with radiation therapy at the University of Virginia from 1968 to 1978 has been reviewed. Staging and treatment policies were consistent throughout this period, and have enabled the influence of histologic classification on treatment results to be evaluated. Large cell nonkeratinizing carcinoma (LCNK) was the most common type, 69%; followed by keratinizing (KSCC), 13%; and adenocarcinoma, 6.

Primary central nervous system germ cell tumors. Effect of histologic confirmation on radiotherapy.

Primary malignant intracranial germ cell tumors are rare lesions responsible for only 0.5% of all central nervous system (CNS) malignancy. With stereotactic localization these lesions can be safely biopsied, and histologic confirmation will affect the ultimate prognosis.

Combined gold seed implantation and external radiotherapy for stage B2 or C prostate cancer.

Patients with clinical stage B2 or C prostatic carcinoma represent a group for which there are several treatment options. We followed the course and outcome of 72 patients with clinical stages B and C prostate cancer who were treated with surgical staging, insertion of gold grains and external radiation at our institutions between 1975 and 1984. Of the patients 44 (61 per cent) had clinical stage B disease and the majority (89 per cent) of these were stage B2 lesions.

Composite pelvic resection. An approach to advanced pelvic cancer.

The definition of resectability has changed in the management of advanced pelvic malignancy. Most tumors previously considered unresectable can be removed by a function-preserving composite resection of the pelvis. We have performed resection in 55 such patients.
