BACKGROUND: The psychosocial adaptation of patients who had undergone a resection of the maxilla for cancer of the maxillary antrum and/or hard palate with the placement of an obturator prosthesis to restore speech and eating function was studied. METHODS: Forty-seven patients were interviewed who had a maxillectomy with an obturator prosthesis at Memorial Sloan-Kettering Cancer Center, an average of 5.2 years (SD = 2.4 years) ago, 94% of whom had some of their soft palate resected. Interviews were conducted by telephone by a trained research interviewer, using a series of questionnaires to assess their satisfaction with the functioning of their obturator, and the psychological, vocational, family, social, and sexual adjustment. Measures included the Obturator Functioning Scale (OFS). Psychosocial Adjustment to Illness Scale (PAIS), Mental Health Inventory (MHI), Impact of Event Scale, and Family Functioning Scale. RESULTS: Using multiple regression and discriminant function analyses, satisfactory functioning of the obturator prosthesis, as measured by the OFS, was found to be (1) the most highly significant predictor of adjustment, as measured by the PAIS (p < .0001) and the MHI Global Psychological Distress Subscale (MHI-GPD) (p < .001), and (2) significantly related to their perception of the negative socioeconomic impact of cancer upon their lives. The most significant predictor of better obturator functioning were the extent of resection of their soft palate (one third or less, p < .001), and hard palate (one fourth or less, p < .01). Specific aspects of obturator functioning that most significantly correlated with better adjustment (PAIS, MHI-GPD) were: less difficulty in pronouncing words (r = .40 and r = .51, respectively, p < .01), chewing and swallowing food (r = .27-.46, p < .05), and less change in their voice quality after surgery (r = .52 and r = .56, respectively, p < .001). CONCLUSIONS: These findings suggest that a well-functioning obturator significantly contributes to improving the quality of life of maxillectomy patients.

Combined chemotherapy and radiotherapy versus surgery and postoperative radiotherapy for advanced hypopharyngeal cancer.

BACKGROUND: Although the standard therapy for locally advanced hypopharyngeal cancer remains surgery and postoperative radiotherapy (RT), alternative treatment approaches include induction chemotherapy and RT. The purpose of this retrospective study was to compare the long-term outcome of these treatments performed in a single institution. METHODS: Twenty-six patients with advanced, resectable, squamous cell carcinoma of the hypopharynx were treated with induction chemotherapy and definitive RT (group I), reserving laryngectomy for salvage. The induction phase of therapy consisted of 2-3 cycles of cisplatin-based chemotherapy followed by conventional fractionated RT to doses of 66-70 Gy. The outcomes of this group of patients were compared with the outcomes of 30 patients with hypopharyngeal cancer who were treated at our institution with surgery and postoperative RT (group II). The median follow-up times of the surviving patients in groups I and II were 5 and 9 years, respectively. RESULTS: The local recurrence-free survival at 5 years from the completion of therapy for group I was 50%, compared with 69% for group II (p = .41). Among patients with T3-T4 primary tumors, the 5-year local control rates were 58% and 59% for groups I and II, respectively (p = .78). The likelihood of larynx preservation, free of local disease at 5 years for group I, was 52%. The 5-year neck recurrence-free survival for groups I and II were 47% and 69%, respectively (p = .66). Among patients with N2-N3 stage disease, the 5-year incidence of neck failure for groups I and II were 73% and 68%, respectively (p = .74). The 5-year distant metastases-free survival for groups I and II were 67% and 57%, respectively (p = .19). The 5-year disease-free survival rates for groups I and II were 30% and 42%, respectively (p = .9). The 5-year overall survival rates for groups I and II were 15% and 22%, respectively (p = .65). CONCLUSIONS: Nonsurgical therapy for advanced stage hypopharyngeal cancer provides survivorship comparable with that achieved with standard approaches of surgery and postoperative RT. However, despite the therapy, the outcome is poor. Future studies will need to explore new treatment strategies in an effort to improve upon the outcome for this group of patients.

Postoperative radiotherapy for oral cavity cancers: impact of anatomic subsite on treatment outcome.

We have retrospectively reviewed the treatment results of postoperative radiotherapy (RT) for advanced oral cavity cancers. The purpose of this study was to determine the impact of anatomic subsite on the results of treatment. Between 1975 and 1985, 51 patients with squamous cell carcinoma of the oral tongue (OT = 29 patients) and floor of mouth (FOM = 22 patients) were treated with combined surgery plus RT. All had an indication(s) for RT including advanced primary disease (T3 or T4) (29 patients), close or positive margins (34 patients), and multiple positive neck nodes and/or extracapsular extension (41 patients). With a median follow-up of 6 years, the 5-year actuarial local control rate was 74% and the rate of distant metastasis (DM) was 34%. Despite the similar T stage, margin status and median RT dose, the 5-year actuarial local failure rate was 38% for OT vs. 11% for FOM (p = 0.03). Furthermore, the median survival after recurrence was 9 months for OT and 40 months for FOM (p = 0.02). At 5 years the determinate survival for both sites was (55%), and the likelihood of developing a second malignancy was 31%. The likelihood of developing DM was 50% for FOM (N0-N1 = 3 of 12, N2-N3 = 8 of 10) and 21% for OT (N0-N1 = 4 of 21, N2-N3 = 1 of 8). This study highlights significant differences between FOM and OT cancers in response to combined surgery and RT. Future strategies should be directed at the enhancement of local control for OT and better systemic therapy for those with advanced N-stage FOM.(ABSTRACT TRUNCATED AT 250 WORDS)

Median mandibulotomy: a critical assessment.

Median mandibulotomy (mandibular "swing") has supplanted mandibular resection for access to oral and oropharyngeal tumors when there is intervening grossly normal tissue between the tumor and bone. It has also proved useful for exposure in selected patients with deep lobe parotid or parapharyngeal space tumors. We have reviewed our experience with 313 mandibulotomies performed between 1959 and 1988 with emphasis on indications, complications, and modifications in technique. Most of our mandibulotomy patients had an uncomplicated recovery, but osteotomy-related complications occurred in 20%. These complications were usually minor and no instances of nonunion were recorded. There was no apparent relationship to antecedent or postoperative radiotherapy. Dental splints were used only in selected patients (40%). The technique of osteotomy has been evolving in recent years. Paramedian, rather than median mandibulotomy, minimizes trauma to the genioglossus, geniohyoid, and digastric muscles. Miniplates offer a useful alternative to conventional wire fixation. Preoperative dental assessment has facilitated better occlusion postoperatively in dentulous patients.

Head and neck sarcoma: report of the Head and Neck Sarcoma Registry. Society of Head and Neck Surgeons Committee on Research.

A Head and Neck Sarcoma Registry was established by the Society of Head and Neck Surgeons to review treatment results of a rare tumor by surgeons with special interest in this anatomic site. Two hundred fourteen patients were analyzed. There were 194 adult tumors and 20 pediatric tumors. The major sites included parotid and neck, 20%; face and forehead, 18%; maxilla and palate, 13%; scalp, 12%; mandible, 11%; paranasal sinuses, 7%; larynx, 2%; and oral cavity, 5%. Eighty-four percent were resectable. The disease-free survival was 56%; overall survival was 70% at 5 years. Major determinants of survival were adequacy of resection (margins free of tumor) and tumor type. Survival differed according to tumor cell type (tumor grade was not available). Patients with chondrosarcoma and dermatofibrosarcoma had survival approaching 100%. Patients with malignant fibrous histiocytoma (MFH) and fibrosarcoma (FSA) had intermediate survival of 60% to 70%. The worst survival, less than 50% at 5 years, occurred in patients with osteosarcoma, angiosarcoma, and rhabdomyosarcoma in decreasing order. This suggests a rationale for identifying high-risk patients for prospective adjuvant protocols. This study emphasizes the value of recording uncommon tumors to provide relevant information for future study and possibly therapy.

Innervation of the trapezius muscle by the intra-operative measurement of motor action potentials.

Although the surgical anatomy of the spinal accessory nerve and the cervical plexus has been extensively described, the exact motor innervation of the trapezius has been controversial. Attempts to resolve this question have involved anatomic or electrophysiologic studies in human embryos and animals. Extrapolation of the results to adult humans may not be correct. Accurate identification of muscle innervation is obtainable by intra-operative measurement of motor action potentials produced by direct stimulation of the accessory nerve and the cervical plexus. The study involved 14 patients undergoing supraomohyoid or modified neck dissections. Under direct vision, stimulating electrodes were placed on the identified nerves and motor action potentials, and latencies were recorded by surface electrodes placed over the three portions of the trapezius. In 13 patients, when the accessory nerve was stimulated, motor action potentials were obtained in 13 of 13 in the first portion, 11 of 13 in the second portion, and 10 of 13 in the third portion of the trapezius. In the last patient, the accessory nerve ended in the sternocleidomastoid muscle, and innervation of the trapezius was via C3 as demonstrated by motor action potentials. Responses when the roots of the cervical plexus were stimulated varied. Three patterns were seen: In the first group (seven patients), motor action potentials were distinct from those recorded when the accessory nerve was stimulated. Additionally, latencies were different from those of the accessory nerve. The second group (four patients) had motor action potentials that were similar to those obtained from stimulation of the accessory nerve, although their corresponding latencies were different.(ABSTRACT TRUNCATED AT 250 WORDS)

Nonsquamous cell malignant neoplasms of the nasal cavities and paranasal sinuses.

BACKGROUND: Nonsquamous cell malignant tumors of the nasal cavity and paranasal sinuses are an uncommon and diverse group of neoplasms. Our goal was to define the relative frequency and distribution of these neoplasms, as well as treatment and outcome. METHODS: This retrospective study analyzed 106 patients with nonsquamous cell malignant neoplasms of the nasal cavity and paranasal sinuses treated at our institution between 1966 and 1982. RESULTS: Pathology included: salivary type carcinoma (33 patients); sarcoma (25 patients); melanoma (18 patients); esthesioneuroblastoma (11 patients); lymphoma (11 patients); and anaplastic cancer (9 patients). Most tumors arose in the nasal cavity (50%), followed by the antrum (39%), ethmoid sinus (9%), and frontal sinus (2%). Fifty-four percent of all patients were treated with surgery alone. Determinate 5-year and 10-year cure rates were: esthesioneuroblastoma, 70% and 50%; lymphoma, 45% and 30%; anaplastic, 33% and 25%; salivary, 31% and 18%; sarcoma, 25% and 21%; and melanoma, 19% and 0%. CONCLUSIONS: Overall survival for patients with nonsquamous cell malignant neoplasms of the nasal cavity and paranasal sinuses is poor, particularly with follow-up extended to 10 years. Local recurrence is the major source of treatment failure. We were unable to demonstrate any survival advantage in the group of patients who received surgery and radiotherapy in combination.
