RESUMO

Background: The optimal regimen of chemotherapy and reirradiation (re-XRT) for recurrent head and neck squamous cell carcinoma (HNSCC) is controversial. We report the final outcomes of a multicenter phase II trial evaluating cetuximab and cisplatin-based chemotherapy concurrent with re-XRT for patients with recurrent HNSCC. Materials and methods: Patients with unresectable recurrent disease or positive margins after salvage surgery arising within a previously irradiated field with KPS ≥ 70 were eligible for this trial. Cetuximab 400 mg/m2 was delivered as a loading dose in week 1 followed by weekly cetuximab 250 mg/m2 and cisplatin 30 mg/m2 concurrent with 6 weeks of intensity-modulated radiotherapy to a dose of 60-66 Gy in 30 daily fractions. Patients who previously received both concurrent cetuximab and cisplatin with radiation or who received radiotherapy less than 6 months prior were ineligible. Results: From 2009 to 2013, 48 patients enrolled on this trial, 2 did not receive any protocol treatment. Of the remaining 46 patients, 34 were male and 12 female, with a median age of 62 years (range 36-85). Treatment was feasible and only 1 patient did not complete the treatment course. Common grade 3 or higher acute toxicities were lymphopenia (46%), pain (22%), dysphagia (13%), radiation dermatitis (13%), mucositis (11%) and anorexia (11%). There were no grade 5 acute toxicities. Eight grade 3 late toxicities were observed, four of which were swallowing related. With a median follow-up of 1.38 years, the 1-year overall survival (OS) was 60.4% and 1-year recurrence-free survival was 34.1%. On univariate analysis, OS was significantly improved with young age (P = 0.01). OS was not associated with radiation dose, surgery before re-XRT or interval from prior XRT. Conclusions: Concurrent cisplatin and cetuximab with re-XRT is feasible and offers good treatment outcomes for patients with high-risk features. Younger patients had significantly improved OS.

RESUMO

Using variational cluster perturbation theory we study the competition between d-wave superconductivity (dSC) and antiferromagnetism (AF) in the t-t(')-t('')-U Hubbard model. Large scale computer calculations reproduce the overall ground-state phase diagram of the high-temperature superconductors as well as the one-particle excitation spectra for both hole and electron doping. We identify clear signatures of the Mott gap as well as of AF and of dSC that should be observable in photoemission experiments.

RESUMO

BACKGROUND: The incidence of hypothyroidism was assessed retrospectively from a data base of 155 patients with head and neck carcinoma who were treated at the Cleveland Clinic Foundation between 1990 and 1997. METHODS: One hundred patients were randomized between radiotherapy (RT) (66-72 grays in single daily fractions) and RT with concurrent chemotherapy (CT) using 5-fluorouracil and cisplatin. An additional 55 patients received RT and CT without randomization. Primary site surgery was performed for tumor persistence or recurrence and included a thyroidectomy in nine patients. These nine patients, along with three patients who had hypothyroidism prior to treatment, were excluded from the analysis. At regular intervals after the completion of treatment, all patients were evaluated for the development of hypothyroidism, defined as a serum thyroid-stimulating hormone (TSH) level > 5.5 microU/mL. RESULTS: With a median follow-up for 143 evaluable patients of 4.4 years (range, 1.5-9.2 years), the 5-year Kaplan-Meier projected incidence rate of hypothyroidism was 48%, and the 8-year projected incidence rate was 67%. The median time to the development of hypothyroidism was 1.4 years (range, 0.3-7.2 years). The likelihood of developing hypothyroidism could not be predicted according to age, gender, primary site, tumor or lymph node status, overall stage, RT dosage to the primary site or to the neck, or inclusion of CT in the treatment plan. Only race proved predictive, with no African-American patients developing hypothyroidism (P = 0.02). CONCLUSIONS: The authors conclude that the incidence rate of hypothyroidism after patients undergo RT for head and neck carcinoma is higher than generally reported and that TSH screening after treatment appears justified.

RESUMO

BACKGROUND: Multimodality treatments for patients with squamous cell head and neck carcinoma often produce significant mucositis and dysphagia, mandating enteral nutritional support. Patient preference has resulted in the increasing use of percutaneous endoscopic gastrostomy (PEG) tubes rather than nasogastric (NG) tubes. Anecdotal observations of prolonged PEG dependence and of a need for pharyngoesophageal dilatation in PEG patients prompted a retrospective review of the use of both types of feeding tubes. METHODS: Patients who were treated on clinical trials of radiotherapy or chemoradiotherapy for squamous cell head and neck carcinoma between 1989 and 1997 were reviewed retrospectively. Data were gathered regarding demographics, primary tumor site, T and N classifications, and the need for feeding tube placement. In patients requiring feeding tubes, the type and duration of the feeding tube, the need for tracheostomy, the need for pharyngoesophageal dilatation, and the degree of mucositis and dysphagia at baseline and at 1 month, 3 months, 6 months, and 12 months after beginning treatment were recorded. Comparisons were then made between the NG and the PEG groups. RESULTS: Ninety-one feeding tubes were placed in 158 patients over the 8-year interval. A hypopharyngeal primary site, female gender, a T4 primary tumor, and treatment with chemoradiotherapy were predictive of a need for feeding tube placement. NG tubes were placed in 29 patients, and PEG tubes were placed in 62 patients. PEG patients had more dysphagia at 3 months (59% vs. 30%, respectively; P = 0.015) and at 6 months (30% vs. 8%, respectively; P = 0.029) than NG patients. The median tube duration was 28 weeks for PEG patients compared with 8 weeks for NG patients, (P < 0.001). Twenty-three percent of PEG patients needed pharyngoesophageal dilatation compared with 4% of NG patients (P = 0.022). These end points could not be correlated with age, stage, primary tumor site, or tracheostomy placement. CONCLUSIONS: Although patients treated for head and neck carcinoma find that the PEG tube is a more acceptable route for enteral nutrition than the NG tube, in the authors' experience, a PEG tube was required for longer periods of time and was associated with more persistent dysphagia and an increased need for pharyngoesophageal dilatation. A randomized prospective trial is needed to test these observations.

RESUMO

The treatment of advanced squamous cell carcinoma involves a multidisciplinary approach among various physicians and ancillary personnel. The role of the head and neck surgeon continues to change, as concurrent chemotherapy and radiotherapy protocols have evolved in the initial management of this challenging patient population. More and more, the surgeon is called upon to operate on those patients with persistent or recurrent disease despite initial treatment with chemotherapy and radiotherapy. The purpose of this article is to analyze complications and outcomes of surgery in patients who have already received radiotherapy and chemotherapy.

RESUMO

HYPOTHESIS: P53 and Ki-67 status will predict response to treatment, organ preservation, and survival in patients with advanced squamous cell cancers of the head and neck treated with chemoradiotherapy (CRT). STUDY DESIGN: Retrospective analysis of p53 and Ki-67 status from the CRT arm of a randomized, controlled trial (n = 50) and from patients receiving the same treatment but not enrolled in the trial (n = 55). METHODS: P53 and Ki-67 status were established from archived tissue samples using immunohistochemical (IHC) staining. Tumors were positive for p53 (p53+) when more than 2% of cells stained for p53 and were positive for Ki-67 (Ki-67+) when any cell stained for Ki-67. End points were tumor response, tumor recurrence, survival status, and organ preservation at last follow-up, and time to events. Predictive models were calculated for each outcome. RESULTS: Neither marker predicted tumor response to treatment. P53+ status was associated with tumor recurrence (P =.003) and locoregional recurrence (P =.003). Adjusting for time to event, p53+ status was significantly related to a lower recurrence-free survival (P =.004), lower disease-specific survival (P =.04), lower overall survival with primary site preservation (P =.03), and lower disease-specific survival with primary site preservation (P =.003). Multivariate analysis revealed that p53+ status was significantly related to a lower recurrence-free survival (P =.01, risk ratio [RR] = 3.65) and lower disease-specific survival with organ preservation (P =.02, RR = 3.41). Ki-67+ status was not related to any variables. However, multivariate analysis revealed that Ki-67+ was significantly related to a lower overall survival (P =.05, RR = 2.03). The combination of both markers negative (p53-/Ki-67-) was associated with a lower incidence of tumor recurrence (P =.02), lower locoregional recurrence (P =.01), and fewer second primary lesions (P =.04). Adjusting for time to event, p53-/Ki-67- status was significantly related to a higher recurrence-free survival (P =.02), higher disease-specific survival with primary site preservation (P =.02), and higher overall survival with primary site preservation (P =.02). Multivariate analysis revealed that p53-/Ki-67- status was significantly related to a higher overall survival with site preservation (P =.01, RR = 2.78). CONCLUSIONS: P53 and Ki-67 status appear to be related to the various survival end points considered in this study. However, this relation does not seem to be sufficient to warrant treatment modifications. Closer follow-up may be justified in both p53+ and Ki67+ patients to detect recurrence or a second primary at an earlier stage, possibly improving survival.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

The role and optimal use of audiometry in monitoring for cisplatin ototoxicity are incompletely defined. Audiograms were obtained from 217 patients before treatment with cisplatin-based chemotherapy for cancers of the esophagus, lung, or head and neck. Posttreatment audiometry then was conducted in 53 of these patients. Chemotherapy consisted of two (87%) or three (13%) courses of cisplatin at a dose of 20 mg/m2/day given as a continuous intravenous infusion over 4 days. Simultaneous 5-fluorouracil or paclitaxel also was given, and 38% received concurrent radiation therapy to the head and neck. Air-conduction thresholds for each ear were obtained at 250, 500, 1000, 2000, 4000, 6000, and 8000 Hz. Three three-frequency pure-tone averages (PTA) also were calculated. Framingham gender-specific, age-adjusted norms were used, beginning at age 60 to correct for presbycusis, and the upper limit of normal was calculated as the greater of the Framingham mean plus twice the standard error, or 25 dB. Hearing abnormality was defined as a threshold >10 dB above the norm for any PTA, or >20 dB above the norm for any individual frequency. Hearing loss was defined as an elevation over baseline threshold of >10 dB for any PTA or >20 dB for any individual frequency. Of the 217 patients who underwent baseline testing, 57 (26%) were found to have hearing abnormality in excess of the expected presbycusis. Post-cisplatin audiograms demonstrated hearing loss in 19 of the 53 retested patients (36%) when compared with their own baseline. As determined by tympanometry, none of these subjects had a conductive component to their hearing loss. These observations were independent of the duration of follow-up after treatment and of the total dose of cisplatin administered. The authors conclude that significant preexisting hearing abnormality is common in this patient population and that, even after low-dose cisplatin administration, additional hearing loss occurs frequently. Baseline testing is mandatory if follow-up studies are to be adequately interpreted.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

BACKGROUND: Extranodal non-Hodgkin lymphoma (NHL) of the head and neck is a relatively uncommon disease. Over the last 3 decades, a variety of systems, including the Rappaport, Luke-Collins, and Working Formulation classifications, have been used to classify extranodal NHLs of the head and neck. Most studies have included a relatively small number of patients, used different modalities of therapy, and did not include all head and neck sites. These limitations make comparisons between different studies and drawing any conclusions difficult. OBJECTIVES: To describe in a uniform fashion a relatively large number of patients with extranodal NHL of the head and neck treated at the same institution, using only the most current classification system and to describe the clinical features, behavior, and outcome of this relatively uncommon, but potentially curable disease. DESIGN: A retrospective study of 98 patients with extranodal NHL of the head and neck. All patients were reclassified according to the Working Formulation system (regardless of the time of diagnosis) in order to uniformly define the clinical course of this disease in the head and neck. SETTING: A tertiary care referral center. RESULTS AND CONCLUSIONS: The sinonasal tract was the most commonly involved site (25%). If the nasopharynx (16%), tonsil (12%), and base of tongue (8%) are grouped together, this combined site (Waldeyer ring) becomes the most common site of disease (36%). Patients with tonsillar lymphoma had a 20% incidence of associated gastrointestinal involvement. Approximately 50% of the patients had associated nodal disease, and only 20% had systemic or B symptoms. Three fourths of the patients had stage I or II disease, and approximately two thirds had intermediate-grade lymphoma. Radiation therapy was the primary modality of therapy for localized disease (stages I and II), especially for low-grade lymphomas. Combination chemotherapy with or without radiation was used for more advanced disease and for intermediate- and high-grade lymphomas. Surgery was limited to establishing the diagnosis. Two thirds of the patients had a remission after initial therapy. Two thirds of these patients had no further relapse. Three fourths of the patients with relapse after initial remission died of their disease. The overall and disease-free survival rates for all patients were 60% and 50%, respectively. Outcome of therapy was related to stage and histologic grade. Patients with lymphomas of high histopathologic grade and recurrent and recurrent and disseminated disease had the poorest prognosis.

RESUMO

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 (

RESUMO

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.

RESUMO

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.

RESUMO

Tobacco and alcohol abuse are the major known risk factors for the development of squamous cell head and neck cancer (SCHNC). Information about this disease in nonsmokers, however, is limited. We retrospectively studied a group of 59 tobacco nonusers with SCHNC, diagnosed since 1986 at the Cleveland Clinic Foundation (CCF). Two objectives were defined: (a) to characterize this nonsmoking population of patients and identify any significant differences compared with a control population consisting of all patients diagnosed with SCHNC at the CCF between 1986 and 1993 and (b) to determine the prevalence of exposure to environmental tobacco smoke in this nonsmoking group of patients with SCHNC and compare it with the environmental tobacco-smoke exposure in a second, control population of non-SCHNC, nonsmoking patients matched for age, race, sex, and alcohol use. The group of nonsmoking patients with SCHNC was notable for only rare alcohol abuse, a preponderance of whites, and relatively fewer laryngeal primary tumors. There were significantly more women and more tongue primaries. When compared with the control population without cancer, the nonsmoking patients had a significantly higher risk of exposure to environmental tobacco smoke both in the home and in the workplace. We conclude that the tobacco nonuser who develops SCHNC is likely to be female and white and to have a primary tongue cancer. A significant association with environmental tobacco smoke exposure is suggested by our data.

RESUMO

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.
