Nicholas J Cassisi: Influence Statistics

PURPOSE: To analyze factors influencing outcome in patients who received postoperative irradiation for advanced squamous cell carcinoma of the oral cavity.

METHODS AND MATERIALS: Between October 1964 and November 1993, 134 patients with 135 previously untreated primary invasive squamous cell carcinomas of the oral cavity (excluding the lip) were treated postoperatively with continuous courses of external-beam irradiation at the University of Florida. All patients had a minimum follow-up ...

This is an analysis of 161 patients with squamous cell carcinoma of the head and neck treated with irradiation to the primary site and neck followed by a neck dissection(s) for clinically positive neck nodes. Patients were treated between October 1964 and December 1982; there was a minimum 2-year follow-up. Fifty-two patients were deleted from analysis of neck disease control because they died of intercurrent disease or cancer less than 2 years from treatment with the neck continuously ...

BACKGROUND: This study was undertaken to analyze the clinical course of patients who developed local (primary) recurrence after high-dose irradiation of T1 -T2 squamous cell carcinoma of the glottic larynx.

METHODS: Between May 1977 and December 1989, 247 patients with previously untreated T1 and T2 invasive squamous cell carcinoma of the glottic larynx were treated for curative intent with radiotherapy. Local recurrence occurred in 26 of 247 patients (11%). Successful surgical salvage ...

BACKGROUND: The purpose of this study was to evaluate the efficacy of the modern diagnostic evaluation for squamous cell carcinoma metastatic to cervical lymph nodes from an unknown head and neck primary site.

METHODS: One hundred thirty patients were evaluated between June 1983 and June 1997. All underwent head and neck examinations, head and neck computed tomography (CT), and/or magnetic resonance imaging (MRI) scans, panendoscopies, and biopsies of head and neck mucosal sites. ...

Between March 1978 and March 1989, 419 patients with 439 moderately advanced or advanced primary squamous cell carcinomas of the head and neck received treatment with curative intent with twice-a-day radiotherapy (120 cGy per fraction with a 4- to 6-hour interfraction interval). Seventy-nine percent of the patients had AJCC stage III or stage IV cancers. The primary site in most patients was the oropharynx, hypopharynx, or larynx. All patients received radiotherapy alone to the primary ...

BACKGROUND: To analyze the likelihood of salvage for patients with recurrence in the neck after radiotherapy.

METHOD: Recurrent disease developed in the neck of 51 patients after primary irradiation for head and neck carcinoma. Salvage was defined as no recurrence of cancer anywhere for at least 1 year after initial salvage treatment and continuously thereafter.

RESULTS: Thirty-three patients (65%) did not undergo a salvage attempt: 18 had unresectable disease; 9 were medically unfit, 4 ...

One hundred thirty-four patients with advanced head and neck cancer were treated with radical surgery and postoperative radiation therapy between October 1964 and October 1984. All patients had greater than or equal to 2 years and 84% had greater than or equal to 5 years of follow-up. All patients included in the study were scheduled to receive continuous-course irradiation following a major cancer operation for previously untreated squamous cell carcinoma of the oral cavity, oropharynx, ...

PURPOSE: To assess the role of radiotherapy alone or in combination with surgery in the treatment of patients with malignant minor salivary gland carcinomas.

METHODS AND MATERIALS: Between October 1964 and November 1992, 95 patients with minor salivary gland carcinomas of the head and neck received radiotherapy with curative intent. Eighty-seven patients were previously untreated, and 8 were treated for postsurgical recurrence. Fifty-one patients were treated with radiotherapy alone, and ...

Between 1964 and 1985, 52 patients were treated with curative intent by radiation therapy alone or in combination with surgery for malignant tumors of minor salivary gland origin. All patients had a minimum follow-up of 2 years, and 80% had a minimum follow-up of 5 years. Twenty-six (50%) were adenoid cystic carcinomas; the remaining histologies included adenocarcinoma, mucoepidermoid carcinoma, and malignant mixed tumors. The most common sites of origin were in the oral ...

BACKGROUND: The treatment of patients with squamous cell carcinoma (SCC) of the oropharynx remains controversial. No randomized trial has addressed adequately the question of whether surgery (S), radiation therapy (RT), or combined treatment is most effective.

METHODS: Treatment results from North American academic institutions that used S with or without adjuvant RT (S +/- RT) or used RT alone or followed by neck dissection (RT +/- ND) for patients with SCC of the tonsillar region or ...

PURPOSE: To evaluate irradiation alone for treatment of base-of-tongue cancer.

PATIENTS AND METHODS: Two hundred seventeen patients with squamous cell carcinoma of the base of tongue were treated with radiation alone and had follow-up for >/= 2 years.

RESULTS: Local control rates at 5 years were as follows: T1, 96%; T2, 91%; T3, 81%; and T4, 38%. Multivariate analysis revealed that T stage (P =.0001) and overall treatment time (P =.0006) significantly influenced local control. The 5-year ...

For patients with squamous cell carcinoma of the head and neck whose primary lesion is managed with radiotherapy, radiotherapy alone or in combination with neck dissection may be used to treat clinically positive neck nodes. Although these two treatment options produce similar control rates for small mobile nodes, it is our impression that radiotherapy plus neck dissection is the preferred treatment for more advanced neck disease. The question that arises is whether the addition of a ...

PURPOSE: We analyzed the clinical course of patients who developed local (primary) recurrence following high-dose irradiation of squamous cell carcinoma of the supraglottic larynx.

METHODS AND MATERIALS: Between October 1964 and July 1991, 206 patients with previously untreated squamous cell carcinoma of the supraglottic larynx underwent radiotherapy with curative intent. Local failure occurred in 46 (22%) patients. Successful surgical salvage was defined as no evidence of recurrent ...

Between October 1964 and December 1983, 48 patients with malignant tumors of the nasal cavity (31), ethmoid sinus (13), or sphenoid sinus (4) were treated with curative intent by radiation therapy. There were 21 squamous cell carcinomas, 14 minor salivary gland tumors (adenocarcinoma, adenoid cystic carcinoma, and mucoepidermoid carcinoma), 3 malignant melanomas, 2 soft tissue sarcomas, and 8 esthesioneuroblastomas. Forty-two patients were treated with irradiation alone and six with ...

PURPOSE: There are no definitive randomized studies that compare radiotherapy (RT) with surgery for tonsillar cancer. The purpose of this study was to evaluate the results of RT alone and RT combined with a planned neck dissection for carcinoma of the tonsillar area and to compare these data with the results of treatment with primary surgery.

PATIENTS AND METHODS: Four hundred patients were treated between October 1964 and December 1997 and observed for at least 2 years. One hundred ...
