RESUMEN

A very rare case of fibrous histiocytoma arising in the pterygopalatine fossa with intracranial extension is described. Despite the histologic absence of nuclear pleomorphism, the tumor rapidly recurred after complete surgical resection. The patient, a 45 year old male, died shortly thereafter. The aggressive nature of our patient's tumor confirms previous observations that an aggressive radiographic appearance has prognostic value when dealing with skeletal and soft tissue tumors. The benefit of multimodal therapy has not been established in these rare head and neck lesions. In the subset of fibrous histiocytomas that invade bone, however adjunctive treatment with radiation and or chemotherapy may be appropriate.

RESUMEN

OBJECTIVE: To evaluate the feasibility and toxic effects of systemic adoptive T-cell immunotherapy in patients with unresectable squamous cell carcinoma of the head and neck (SCCHN). DESIGN: Nonrandomized phase 1 clinical trial. SETTING: Academic tertiary care hospital. PATIENTS: Between April 1, 1996, and September 30, 1998, 17 patients with confirmed recurrent and metastatic SCC of the upper aerodigestive tract were enrolled. Two patients did not receive T cells because of poor vaccine response. Fifteen patients were successfully treated with T-cell immunotherapy. INTERVENTION: Patients were vaccinated on the thigh with irradiated autologous tumor cells admixed with granulocyte-macrophage colony-stimulating factor (GM-CSF) followed by 3 additional daily injections of GM-CSF at the vaccination site. Eight to 10 days later, tumor cell vaccine-draining inguinal lymph nodes were resected, and lymph node lymphocytes were activated with staphylococcal enterotoxin A and expanded in interleukin 2 in vitro. Resulting cultured cells were infused into patients peripherally on an outpatient basis. RESULTS: Toxic effects of infusion were limited to grade 2 reactions in 3 of 16 treatments. One patient required overnight hospitalization for fever and emesis. Median cell expansion was 37 times (range, 4-416 times), and median cell dose was 7.5 x 10(9) (range, 1.3 x 10(8) to 4.2 x 10(10)). Infused cells were predominantly CD3+ (>97%), being a mixture of CD4+ and CD8+ cells. Three patients demonstrated stabilization of previously progressive disease. Two patients experienced favorable clinical courses after adoptive T-cell transfer, including 1 patient with no evidence of disease 4 years after surgical resection of a vertebral body metastasis. CONCLUSIONS: Adoptive immunotherapy is a technically feasible and safe treatment with low toxicity and may demonstrate therapeutic activity in patients with unresectable SCCHN.

RESUMEN

BACKGROUND: The current study presents mature results from a Phase III randomized trial comparing radiation therapy and concurrent chemoradiotherapy in patients with resectable American Joint Committee on Cancer Stage III and IV disease. METHODS: One hundred patients were randomized to receive either radiation therapy alone (Arm A) (at a dose of between 66-72 grays [Gy] at 1.8-2 Gy per day) and the identical radiation therapy with concurrent chemotherapy (Arm B) (5-fluorouracil, 1000 mg/m(2)/day, and cisplatin, 20 mg/m(2)/day, both given as continuous intravenous infusions over 4 days beginning on Days 1 and 22 of the radiation therapy). Primary site resection was planned for patients with residual or recurrent local disease. Cervical lymph node dissection was performed for regional persistent disease or recurrence, or if N2-3 disease was present at the time of presentation. RESULTS: After completing all therapy including surgery, 82% of the patients in Arm A and 98% of the patients in Arm B had been rendered disease free (P = 0.02). At a median follow-up of 5 years (range, 3-8 years), the 5-year Kaplan-Meier projections for overall survival for Arm A versus Arm B were 48% versus 50% (P = 0.55). Kaplan-Meier projections for the recurrence free interval were 51% versus 62% (P = 0.04), projections for a distant metastasis free interval were 75% versus 84% (P = 0. 09), projections for overall survival with primary site preservation were 34% versus 42% (P = 0.004), and projections for local control without surgical resection were 45% versus 77% (P < 0.001). Salvage surgery proved to be successful in 63% and 73%, respectively, of the Arm A and Arm B patients with primary site failure. Unrelated death while free of disease occurred in 22% and 32%, respectively, of Arm A and Arm B patients (P = 0.26). CONCLUSIONS: The addition of concurrent chemotherapy to definitive radiation in patients with resectable Stage III and IV squamous cell carcinoma of the head and neck improves the likelihood of disease clearance, a recurrence free interval, and primary site preservation. However, overall survival does not appear to be improved, reflecting both effective surgical salvage after local recurrence and competing causes of death.

RESUMEN

OBJECTIVE: To determine whether perioperative systemic corticosteroid administration can reduce uvulopalatopharyngoplasty (UPPP) postoperative morbidities (e.g., pain, anorexia, sleep disturbance, mouth odor, and fatigue) or reduce narcotic analgesic usage. STUDY DESIGN: A prospective, double-blinded study with random assignment of treatment agent (placebo or corticosteroid). METHODS: From 1995 to 1998, a consecutive sample of 48 adults presenting for elective UPPP surgery alone or in combination with tonsillectomy or septoplasty, or both, were enrolled. Twenty-eight subjects completed the protocol and were equally distributed by random assignment to intramuscular (IM) and intravenous (IV) doses of placebo (saline) or corticosteroid (60 mg methylprednisolone IM and 12 mg dexamethasone IV). Acetaminophen with codeine analgesic was available to both groups as needed. Subjects recorded a diary of symptom severity scores over the first postoperative week relating to eight commonly reported morbidities (1-4 points) and the daily quantity of narcotic consumed. RESULTS: Statistical comparison (Wilcoxon's rank sum test) showed no significant differences between subjects treated with placebo or corticosteroid on postoperative day 1 or 7. Three subjects (21%) in each treatment group reported no postoperative use of narcotic analgesic. CONCLUSIONS: No statistically or clinically significant benefits were derived from perioperative systemic corticosteroid treatment in this sample of 28 adults treated with UPPP alone or in combination with tonsillectomy or septoplasty, or both. Some individuals tolerate post-UPPP discomfort without a narcotic analgesic.

RESUMEN

BACKGROUND: Since 1989, 105 patients with squamous head and neck cancer have been treated with combined chemoradiotherapy. OBJECTIVE: To examine the effectiveness of using combined chemoradiotherapy on patients with squamous head and neck cancer. DESIGN: Eight-year (1989-1997) single-institution evaluation of 105 patients. METHODS: Treatment consisted of fluorouracil, 1000 mg/m2 per day, and cisplatin, 20 mg/m2 per day, both given as continuous infusions during 4 days beginning on day 1 and 22 of a concurrent radiotherapy course. Radiation was given in single daily fractions of 1.8 to 2 Gy, to a total dose of 66 to 72 Gy. Salvage surgery was performed for any residual or recurrent locoregional disease. Planned neck dissection was recommended for all patients with N2+ neck disease, irrespective of clinical response. RESULTS: The 105-patient cohort consisted of 79 men and 26 women. The primary site was identified in the oral cavity in 6, oropharynx in 46, larynx in 30, and hypopharynx in 20 patients. Two patients had multiple primaries and 1 patient had an unknown primary. There were 4 patients with stage II, 24 with stage III, and 77 with stage IV disease. Grade 3 and 4 chemoradiotherapy toxic effects included mucositis in 88% of patients, cutaneous reaction in 50%, neutropenia in 49%, thrombocytopenia in 12%, and nausea in 5%. There were no deaths secondary to treatment. The mean weight loss was 12% of initial body weight. To date, primary site persistence or recurrence has occurred in only 14 patients (13%). With a mean follow-up of 39 months, 66 patients (63%) are alive and free of disease. The Kaplan-Meier 4-year projected overall survival is 60% with a disease-specific survival of 74%, a distant metastasis-free survival of 84%, and an overall survival with primary site preserved of 54%. CONCLUSIONS: This chemoradiotherapy regimen, although toxic, is tolerable with appropriate supportive intervention. Locoregional and distant control are likely. Primary site conservation is possible in most patients. Chemoradiotherapy appears to have an emerging role in the primary management of head and neck cancer.

RESUMEN

Plasmacytomas are rare tumors that often appear in the head and neck region and are characterized by a monoclonal proliferation of plasma cells. On both clinical presentation and pathologic examination these tumors may be confused with more common tumors of the head and neck. The purpose of this article is to review our experience with these rare neoplasms, with emphasis on clinical, pathologic, and therapeutic features. On retrospective chart review, we identified 20 patients with the diagnosis of plasmacytoma of the head and neck region at the Cleveland Clinic Foundation between 1976 and 1993. Records were reviewed with regard to initial symptoms, location of the neoplasm, diagnostic evaluation, treatment modalities, and survival. Of the 20 cases we identified, the tumor arose in the sinonasal/nasopharyngeal region in 11 (55%). Two cases (10%) represented medullary plasmacytomas, arising in the clavicle and presenting as supraclavicular masses. The mean follow-up was 60.2 months (range 6 to 131 months). In 15 of the 20 cases, immunohistochemistry staining for immunoglobulin light chain production was conducted. One of the two cases (50%) classified as medullary plasmacytoma demonstrated conversion to multiple myeloma, whereas only 2 of 18 cases of extramedullary plasmacytoma (11%) converted to multiple myeloma. The primary modality of treatment was radiation therapy with typical doses of 4500 to 6000 cGy. Kaplan-Meier survival estimates demonstrated 95% survival at 1 year, 82% survival at 5 years, and 10-year estimated survival of 72%. Plasmacytomas of the head and neck region are rare and on initial evaluation must be distinguished from multiple myeloma. The diagnostic evaluation includes appropriate radiologic and pathologic studies including immunohistochemistry. Despite the typical presentation as a locally destructive tumor, plasmacytomas are highly radiosensitive, and 70% to 80% survival may be obtained with the use of radiotherapy. Patients with plasmacytomas require long-term follow-up to detect conversion to multiple myeloma.

RESUMEN

OBJECTIVE: To determine the incidence of minor and major complications in patients with squamous cell carcinoma of the upper aerodigestive tract who require surgical salvage or planned neck dissection after an initial treatment regimen with radiotherapy or concurrent chemoradiotherapy for organ preservation. DESIGN: The medical records of 100 patients treated in a phase 3 trial comparing radiotherapy alone with concurrent chemoradiotherapy for stage III and IV head and neck squamous cell carcinoma were reviewed. Fifty-four patients underwent 59 surgical procedures. Twenty-nine planned neck dissections were performed for persistent neck disease or initial stage N2 or greater. For persistent or recurrent disease at the primary site, 30 salvage operations were performed. SETTING: Academic tertiary care referral center. RESULTS: Complications occurred in 15 (46%) of the 33 procedures in the radiation-only group and 12 (46%) of the 26 procedures in the chemoradiotherapy group. Major complications occurred in 4 (12%) of the procedures in the radiation-only group and 3 (12%) of the procedures in the chemoradiotherapy group. The incidence of minor complications was 33% and 35% in the radiation-only and chemoradiotherapy groups, respectively. The major complication rate for salvage operations did not differ between the radiation-only and chemoradiotherapy groups (16% and 27%, respectively; P=.79 by chi2 test). The incidence of major complications in planned neck dissections was 7% of the radiation-only group and 0% of the chemoradiotherapy group. CONCLUSIONS: After radiation or concurrent chemoradiotherapy, surgery can be performed with an acceptable rate of major complications. Adding chemotherapy did not increase the incidence of surgical complications. These results differ from other reports in the literature.

RESUMEN

BACKGROUND: Treating the neck after organ-preservation treatment with radiotherapy or chemoradiotherapy can be problematic. METHODS: To develop management guidelines, we reviewed the results of a 100-patient phase-3 trial that had compared outcome after radiotherapy alone with outcome after chemoradiotherapy for head and neck cancer. Patients were randomly assigned to receive radiotherapy alone or concurrent chemoradiotherapy. After completing therapy, patients were reassessed, and surgery was recommended for persistent disease at the primary site or neck and for all patients with stage N2-3 neck nodes regardless of clinical response. RESULTS: Of the 47 patients with stage NO-1, 43 had a complete response (CR); of the 18 N1 patients, all but 4 had a CR. One of these 4, as well as 5 others among the NO-1 patients, underwent neck dissection (n = 6). No disease was found on pathologic examination, and no patient had neck recurrence. Of the remaining 41 N0-1 patients, 3 had disease progression and received no further therapy. Of the 38 others, 4 had neck recurrence, with 3 recurring at the primary site. Of the 53 with stage N2-3, 23 had less than a complete response (

RESUMEN

BACKGROUND: A phase III randomized comparison of radiotherapy alone versus combination chemotherapy and concurrent continuous-course radiotherapy was performed at the Cleveland Clinic Foundation. METHODS: Between March 1990 and June 1995, 100 patients with resectable stage III and IV squamous cell head and neck cancer were randomized to either Arm A: radiotherapy alone, 68-72 Gy at 1.8-2.0 Gy per day; or to Arm B: the identical radiotherapy with concurrent chemotherapy. Chemotherapy consisted of 5-fluorouracil, 1000 mg/m2/day, and cisplatin 20 mg/m2/ day, both given as continuous intravenous infusions over 4 days beginning on day 1 and day 22 of the radiotherapy. At 50-55 Gy, patients were clinically reassessed. If a response was evident, radiotherapy was completed. In non-responding patients, however, radiotherapy was terminated and surgery recommended. After completion of all treatment, salvage surgery was performed, if possible, for any residual primary or nodal disease or for any subsequent locoregional recurrence. RESULTS: Except for an overrepresentation of T1 patients on Arm A, the treatment arms were equivalent. Toxicity was greater in the patients on Arm B with a higher incidence of grade III and IV neutropenia, thrombocytopenia, cutaneous reaction, and mucositis. Feeding tubes were also required more often, and weight loss was greater on the chemotherapy arm. No toxic deaths occurred. With a median follow-up of 36 months, the Kaplan-Meier 3-year projections of relapse-free survival are 52% for Arm A and 67% for Arm B (p = .03), and the likelihood of developing hematogenous metastases is 21% for Arm A and 10% for Arm B (p = .04). Although overall survival is not significantly different, overall survival with successful primary site preservation was 35% for Arm A and 57% for Arm B (p = .02). This difference remains statistically significant in the subsets of patients with laryngeal and hypopharyngeal primaries but not in patients with oropharyngeal primaries. CONCLUSIONS: Continuous-course radiotherapy and concurrent combination chemotherapy is an intensive, toxic but tolerable treatment regimen, which, when compared with radio therapy alone, can produce an improvement in relapse-free survival, a decrease in distant metastases, and an improvement in overall survival with successful primary site preservation.

RESUMEN

Surgical treatment of Zenker's diverticulum is controversial because many different procedures exist. We retrospectively reviewed 87 consecutive patients surgically treated for Zenker's diverticulum at a tertiary care institution from 1976 through 1993. Four surgical procedures were performed: cricopharyngeal myotomy alone (n = 16), excision (hand-sewn) plus myotomy (n = 51), excision (stapler) plus myotomy (n = 11), and diverticulopexy plus myotomy (n = 9). There were three surgical mortalities (3.5%) and a complication rate of 24%. Eighty patients (92%) were available for follow up. Sixty-eight patients (78%) reported excellent relief of symptoms, 10 (13%) reported improvement with occasional symptoms, and two (3%) described persistent dysphagia. No statistical difference in complication rate was found among surgical groups (P = 0.15). Myotomy alone patients had worse outcomes (P = 0.04) compared with the other surgical groups. Median follow-up was 7.5 months.

RESUMEN

The results in 9 patients with unresectable recurrent squamous cell cancer of the head and neck who were treated with aggressive concurrent chemoradiotherapy are reported. Treatment consisted of one or two courses of chemotherapy with 5-fluorouracil 1000 mg/m2/day and cisplatin 20 mg/m2/day, both given as 4-day continuous intravenous infusions, concurrent with radiation therapy. Salvage radiation doses between 30 and 70 Gy were administered. Seven patients had previously undergone an attempt at curative surgery, and 7 had been treated with radiation doses between 52 and 72 Gy. The recurrent disease was locally confined in 3, locoregional in 5, and locoregional with metastases in 1 of the 9 patients. Treatment toxicity was significant and included mucositis, nausea/vomiting, and granulocytopenia, but there were no toxic deaths. Complete tumor clearance was possible in 6 of these 9 patients, and 5 patients remain disease-free at 41+, 43+, 45+, 47+, and 50+ months. Of these 5 patients, 4 had previously been treated with both surgery and radiation, while 1 had only undergone surgery. We conclude that aggressive chemotherapy and concurrent (re)irradiation can be given to patients with unresectable, recurrent, squamous cell cancer of the head and neck. Treatment is tolerable, and disease-free long-term survival is possible. Careful patient selection, however, is required.

RESUMEN

OBJECTIVE: To identify factors predicting prosthesis use and final speech quality in patients undergoing secondary tracheoesophageal puncture (TEP) for voice restoration alter laryngectomy. METHODS: We undertook a retrospective study of 168 patients who underwent secondary TEP at the Cleveland Clinic between June 1980 and October 1993. Factors examined were: patient demographics, extent of initial surgery, method of pharyngeal preparation, history of irradiation, insufflation test results, pharyngeal stricture, and concurrent medical conditions. Univariate and multivariate statistical analyses were performed to identify predictive factors. RESULTS: At last evaluation, 73.8% (124) of the patients were still using the prosthesis. Quality of speech was the only predictor of prosthesis use (p < .001). Phonation on the first day was achieved in 90% (151) of patients. Speech result improved significantly over the first 6 months (p < .001). Univariate analysis found that the need for reconstruction at laryngectomy (p = .04), the presence of pharyngeal stricture (p = .001), and continued prosthetic use (p < .001) were associated with the speech result. There was no significant advantage to the lack of approximation of the pharyngeal constrictors (p = .31). Stepwise logistic regression showed that only the absence of pharyngeal stricture was associated with a better-quality voice (p = .001). CONCLUSION: Tracheoesophageal puncture is a reliable method for restoring voice after laryngectomy. Prosthesis use decreases with time, and good voice quality is the only predictor of continued prosthesis use. In this series the absence of pharyngeal stricture was the only significant predictor of good to excellent speech.

RESUMEN

OBJECTIVE: The purpose of this study was to evaluate our experience with the diagnosis and management of tumors of the parapharyngeal space (PPS), with particular emphasis on the evolving role of magnetic resonance imaging (MRI). METHODS: A case series review of 51 patients with parapharyngeal tumors who underwent surgical excision between 1980 and 1992 were analyzed with regard to presenting signs and symptoms, histologic diagnosis, imaging technique (computed tomography [CT] versus MRI), surgical approach, and outcome. RESULTS: Fifty-one patients underwent surgical excision of a parapharyngeal tumor of which the vast majority (78%) were benign neoplasms. Compared with benign neoplasms, the malignant tumors were much more likely to be associated with pain, trismus, and a cranial nerve deficit. MRI was able to locate the tumor in 20 of 21 patients (95%), while CT was able to localize the tumor in 32 of 38 patients (84%). CONCLUSIONS: MRI, because of its superior soft-tissue resolution and ability to provide imaging in multiple planes, is the imaging modality of choice to diagnose neoplasms of the parapharyngeal space. Because most of these tumors are benign, MRI allows the surgeon to select the surgical approach with the least morbidity.

RESUMEN

STUDY OBJECTIVE: We sought to determine whether preoperative fiberoptic pharyngoscopy (FOP) with Müller's maneuver (dynamic FOP) could be used to establish a subgroup of obstructive sleep apnea (OSA) patients with better outcome after uvulopalatopharyngoplasty (UPPP). DESIGN: Retrospective review of an observational cohort. SETTING: Tertiary care referral center. PATIENTS: Twenty-nine patients who underwent UPPP and nasopharyngeal surgery by one surgeon. INTERVENTION: The patients were divided into two groups based on the findings of preoperative dynamic FOP: group 1 (11 patients) had collapse of the velopharynx and the base of the tongue-epiglottis-hypopharynx (TEH) complex and group 2 (18 patients) had velopharyngeal collapse only. MEASUREMENTS AND RESULTS: Surgical success was defined using a conventional definition (> 50% reduction in the apnea-plus-hypopnea index [OAHI]), and a criterion for cure (> 90% reduction in OAHI and postoperative OAHI < 15). Both groups had a significant improvement in their OAHI. The success rate was significantly higher in patients with velopharyngeal collapse only compared with patients with additional collapse of the TEH complex (78 vs 36% with the conventional definition, and 50 vs 9% using the definition for cure, respectively). Predictive value of dynamic FOP in predicting cure failure when collapse of the TEH complex was present was 91%. CONCLUSIONS: Dynamic FOP may help establish a subgroup of OSA patients with greater likelihood of successful UPPP. The high negative predictive value of dynamic FOP when a criterion for cure is used suggests that this maneuver could best be used to exclude patients with TEH complex collapse from UPPP.

RESUMEN

BACKGROUND: The craniofacial approach is a reliable method for excising tumors involving the anterior skull base. Advances in technique have minimized complications. Although cerebrospinal fluid leaks and meningitis are well-known complications, tension pneumocephalus is not well described. We review two cases and discuss the pathophysiology, clinical manifestations, radiographic features, and treatment of tension pneumocephalus. METHODS: Case study. We reviewed the records of all patients who underwent anterior craniofacial resection at our institution, a tertiary care center, from 1976 to 1993. Among 45 patients identified, 2 had tension pneumocephalus. RESULTS: Neurologic deterioration after anterior craniofacial resection occurred in both patients in the immediate postoperative period. Both patients had extradural intracranial air under pressure and were diagnosed with tension pneumocephalus. In one patient, this was treated by needle aspiration followed by catheter drainage, and the second patient was treated with needle aspiration followed by airway diversion. The first patient recovered fully and was discharged on postoperative day 14; the second patient's mental status did not return to the preoperative level, and he was discharged on postoperative day 23 to a rehabilitative facility. Approximately 3 months later, his level of mentation returned to baseline. CONCLUSIONS: Tension pneumocephalus is a potentially devastating complication that may occur after craniofacial resection. It requires prompt recognition and treatment to minimize morbidity.

RESUMEN

Concurrent radiation therapy and chemotherapy is a promising approach to the treatment of squamous cell head and neck cancer. Toxicity, however, has required either scheduled breaks in radiation therapy administration or compromise in chemotherapy dose intensity. We describe the toxicity and results in 19 patients treated at diagnosis with a continuous course of radiation therapy and intensive concurrent combination chemotherapy using 5-fluorouracil and cisplatin. Toxicity among these 19 patients was significant, including mucositis, myelosuppression, and weight loss, and aggressive supportive efforts were required. No toxic deaths occurred, however. At the end of treatment, all patients had achieved complete control of their primary-site tumor. Primary-site resection was not required in any patient for tumor control, but neck dissections were performed in selected individuals with involved nodes at diagnosis. No patient recurred at the primary site and only a single patient recurred in the neck. We conclude that this chemoradiotherapy schedule is very effective, albeit toxic. Toxicity, however, can be managed with appropriate aggressive supportive measures. Confirmation of these encouraging treatment results will require performance of a randomized clinical trial.

RESUMEN

Obstructive sleep apnea (occlusion of the upper airway despite continued respiratory muscle activity) is accompanied by increased morbidity and mortality from cardiovascular and cerebrovascular disease. Daytime sleepiness due to the disorder may also be a factor in a higher incidence of automobile accidents in these patients. An overnight polysomnogram is used to confirm the diagnosis and assess severity of physiologic disturbances. Initially, simple measures, such as avoidance of alcohol and sedatives before bedtime and sleeping on the side rather than the back, may be tried. Nasal continuous positive airway pressure is considered first-line therapy, and compliance can be improved by education and counseling of the patient. Uvulopalatopharyngoplasty is beneficial in only 50% of patients. Tracheostomy gives the most consistent long-term benefit but is accompanied by significant emotional morbidity.
