Between 1970 and 1980, we treated 107 previously untreated patients with biopsy-proven carcinoma of the nasopharynx by megavoltage external radiation therapy to the primary site, the base of the skull, and both sides of the neck. Eighty-seven percent of the patients had stage IV disease (American Joint Committee, 1980). Eighteen patients developed distant metastases as the first site of relapse. Metastases appeared within 6 months after treatment in 50% of these 18 patients, and in 94% within 2 years. Median survival after the development of distant metastases was 6 months. The most sensitive predictor of which patients would develop distant metastases was the size of cervical lymph node metastases at initial presentation (P = 0.003); patients without palpable cervical nodes or with cervical nodes smaller than 3 cm were the least likely to develop distant metastases (10%), followed by those patients who had cervical nodes measuring 3 to 6 cm (25%), followed by those who had cervical nodes larger than 6 cm, (almost 50%). The incidence of distant metastases was not significantly influenced by age, sex, birthplace, histology, or T-stage. Studies aimed at decreasing the morbidity and mortality from distant metastases in carcinoma of the nasopharynx should be undertaken in patients who present with bulky cervical metastases.

Objectives/Hypothesis: Many of the hallmarks of a very successful medical career, such as recognition as a leader in a field of medicine, making important contributions to medical knowledge of the day, and a steadfast dedication to patient care, had already been achieved by Dr. John Hancock Douglas. Therefore, the mystery surrounding his dismissal from membership of the newly formed American Laryngology Society (now the ALA) and his tragic demise stand in stark contrast. We discuss the model professional life and mysterious but tragic final days of this very important laryngologist of the 19th century. Study Design/Methods: A historical vignette. Results: Dr. Douglas's professional qualities of leadership of the American Sanitary Commission, his various contributions to the advancement of medical knowledge during that era, and his steadfast dedication to the care of his patients represent highlights of a very honorable professional career. His final demise, bankrupt, in an ill state of health, and stripped of his professional appointment to the ALA, seems an unjust end to the life of this notable and magnanimous laryngologist. Conclusions: We offer this historical review of the life and demise of Dr. John H. Douglas as a tribute to this important figure in our profession's history.

Background There are several management options for patients with squamous cell cancer of the base of tongue. We have had an interest in using primary radiotherapy with or without neck dissection, in an effort to provide optimal oncologic as well as functional outcomes. Methods From 1981 to 1995, 68 patients with primary squamous cell cancer of the base of tongue were managed with primary radiotherapy, with neck dissection added for those who were initially seen with palpable lymph node metastases. Ages ranged from 35 to 77 years (median age, 55 years). There were 59 men and 9 women. T Stage distribution was: T1, 17; T2, 32; T3, 17; T4, 2. Fifty-eight patients (85%) were initially seen with nodal metastases. Initial treatment generally involved external-beam radiotherapy (EBRT) to the primary site and upper neck (54 Gy) and to the low neck (50 Gy). A 192-Ir brachytherapy boost (20–30 Gy) to the base of tongue was done about 3 weeks later, at the same anesthesia used for the neck dissection. All patients had temporary tracheostomy. Follow-up ranged from 1 month to 151 months (median, 36 months). Nine patients received neoadjuvant chemotherapy as part of a larynx-preservation protocol. Results Actuarial 5- and 10-year local control is 89% and 89%, distant metastasis free survival is 91% and 76%, diseasefree survival is 80% and 67%, and overall survival is 86% and 52%, respectively. Complications occurred in 16%. Conclusions Our long term data clearly demonstrate that primary radiotherapy produces excellent oncologic outcomes. © 1998 John Wiley & Sons, Inc.

Reconstruction after total maxillectomy with preservation of the orbital contents is technically more challenging than when the maxillectomy is combined with orbital exenteration. Reconstruction of such defects should (1) provide support to the orbital contents, (2) obliterate any communication between the orbit and nasopharynx, (3) reconstruct the palatal surface, and (4) achieve facial symmetry and a good aesthetic result. We report our experience in performing reconstructive surgery on 14 patients who had a total maxillectomy and preservation of the orbital contents using nonvascularized bone grafts for reconstruction of the orbital floor and maxilla, in conjunction with a soft-tissue free flap or pedicled muscle flap. The orbital floor was reconstructed using split ribs in six cases (42.9 percent), split calvaria in six cases (42.9 percent), and iliac crest graft in two cases (14.3 percent). A myocutaneous rectus abdominis free flap was used for soft-tissue reconstruction and resurfacing of the palatal mucosa in twelve patients (85.7 percent), and a temporalis muscle transposition was used in two elderly patients (14.3 percent). One patient died 2 days after surgery. Mean follow-up and aesthetic and functional results were assessed in the remaining 13 patients a minimum of 6 months postoperatively. In 9 of these 13 patients (69.2 percent), postoperative radiotherapy was administered. No reexplorations or free flap failures were observed. One rectus flap developed partial necrosis of the skin island intraorally without affecting the final result. All patients had adequate functional vision. One patient had a mild vertical dystopia; there were no cases of enophthalmos. Ectropion was the most common undesirable result and was present in 10 of 13 cases (76.9 percent). It was graded as mild in four cases (40.0 percent), moderate in four cases (40.0 percent), and severe in the remaining two cases (20.0 percent). Speech was considered normal in six cases (46.2 percent), near normal in six cases (46.2 percent), and intelligible in one case (7.7 percent). Chewing function was considered good (soft to unrestricted diet) in all cases except for one patient who was only able to eat a pureed diet. Aesthetic results after immediate reconstruction were considered good in nine cases (69.2 percent) and fair in four cases (30.8 percent). Primary reconstruction of total maxillectomy defects with orbital content preservation remains a complex problem without a perfect solution. The combination of nonvascularized bone grafts for orbital/maxillary reconstruction with a soft-tissue free flap is a safe, reliable, and effective method of maximizing postoperative functional and aesthetic results.

Background Our study is a prospective evaluation of unresectable malignant cancers of the head and neck treated with concomitant chemotherapy and radiotherapy (RT) using delayed accelerated fractionation (concomitant boost). Methods Between January 1988 and March 1995, 82 patients with unresectable cancers of the head and neck were enrolled in this phase II study. Of these, 52 patients were treated and followed for a minimum of 3 years and are the subject of this analysis. All patients had T4 lesions and were stage IV according to the American Joint Committee on Staging Criteria (AJCC). Patients received RT with accelerated fractionation to a total of 70 Gy in 6 weeks using a concomitant-boost technique. Concomitant cis platin (100 mg/M2) was given on days 1 and 22 of RT. Twenty-seven patients received mitomycin-C (7.5 mg/M2) on days 1 and 22, and 1 patient received mitomycin-C on day 1. In addition, 27 patients received adjuvant chemotherapy with cis platin and vinblastine. The mean follow-up was 45 months (range, 36–72 months). The minimum follow-up for surviving patients is 3 years. Results At 3 years, the local control rate was 58%. Three-year local control rates for paranasal sinus, nasopharynx, oropharynx, and larynx/hypopharynx were 78%, 78%, 64%, and 100%, respectively. For all patients, the distant-metastasis-free survival was 56%, and the overall survival rate was 36%. Patients with oral cavity cancers experienced worse overall survival versus other sites, 0% versus 47% (p = .03). Salivary cancers also showed worse survival versus other sites, 0% versus 47%, but was not statistically significant. Severe acute complications occurred in 34% of patients. Treatment-related toxicity also resulted in the death of 2 patients. Severe late complications occurred in 7% of patients. Conclusions Treatment of this poor prognostic group of patients with aggressive chemotherapy and RT produced surprisingly good local control and survival. © 1998 John Wiley & Sons, Inc.

Background. Patients with bilateral retinoblastoma are well recognized to have high risk of developing a second malignancy, but there are little published data regarding the outcome of these patients following treatment. Patients and Methods. We identified 15 patients with a history of bilateral retinoblastoma who received treatment at Memorial Sloan-Kettering Cancer Center for a newly diagnosed second malignancy. The median age of second tumor occurrence was 18 years (range 10-32 years). Three patients later had a third tumor (18 tumors total). Tumor sites included facial structures in 14 cases and extremities in 4. Histologies included osteosarcoma (5), leiomyosarcoma (5), high-grade spindle cell sarcoma (3), malignant fibrous histiocytoma (3), malignant mesenchymoma (1), and angiosarcoma (1). Results. Nine patients are alive: 7 disease free at a median of 29 months (range 6-214 months) and 2 with residual disease 59 and 148 months post-diagnosis of the second malignancy. Six patients have died at a median of 31 months (range 16-98 months) after diagnosis of the second malignancy. Conclusions. Patients with a history of bilateral retinoblastoma who develop a second malignancy may enjoy extended periods of survival. Aggressive therapy appropriate to the tumor histology and site is indicated.

Background Management of osteoradionecrosis (ORN) remains a difficult and challenging problem. The traditional approach using debridement, antibiotics, and occasionally hyperbaric oxygen is usually successful in treating minimal ORN. However, when bone and soft-tissue necrosis is extensive, the conservative approach usually requires intensive care over a long period of time and often yields unsatisfactory functional and cosmetic results. Methods Within the past 5 years, we have used radical resection of the mandible with immediate microvascular reconstruction in the treatment of extensive ORN of the mandible. This aggressive surgical approach was used in six patients with advanced ORN of the mandible, all of whom had failed initial conservative treatment, including hyperbaric oxygen therapy in three. A fibular free graft with microvascular anastomosis was used in all patients. Results All the patients healed primarily with minimal postoperative morbidity and excellent cosmetic results. Two patients subsequently required removal of some of their hardware. One patient had placement of osseointegrated implants with an excellent cosmetic and functional result. Conclusion Microvascular reconstruction with its own blood supply seems to expedite bone healing and limit further osteoradionecrosis of the remaining mandible. Although prevention is the primary goal in radiation injury, our experience suggests that radical resection with free microvascular reconstruction offers significant advantages to selected patients with extensive ORN of the mandible. © John Wiley & Sons, Inc.

Background Many adjectives are used to describe maxillectomy procedures, such as radical, total, extended, subtotal, medial, partial, and limited. The variety of nomenclature in our own Service database testifies that much confusion exists. Methods We have reviewed a 10-year experience with 403 maxillectomies performed between 1984 and 1993. Based on our retrospective reassessment, the operations were grouped into one of three categories. The term “limited” (LM) was applied to any maxillectomy which primarily removed one wall of the antrum. Designated “subtotal” (SM) was any procedure which removed at least two walls, including the palate. We listed as “total” (TM) only those who had a complete resection of the maxilla. Hospital charts were selectively reviewed, and each of the three types of maxillectomy was analyzed to determine the histology and site of the index cancers and the incidence of complex reconstruction. Results We determined that the maxillectomy performed in 230 patients (57%) was a LM. Tumor site and extent defined five different approaches in this cohort: peroral, 73; medial maxillectomy, 53; anterior craniofacial, 43; upper cheek flap, 42; and transfacial, 19. Subtotal maxillectomy or TM was performed in 135 and 38 (34% and 9%, respectively), almost 90% of whom had a cheek flap approach. Only 51 patients had an orbital exenteration, including 27 of the 38 (71%) of those who had a TM. Complex repair was employed in a total of 63 patients (16%), most often in those having TM (14 of 38, 37%). Conclusions Classification of maxillectomy either as LM, SM, or TM is useful and feasible. To define a LM, the portion of the maxilla removed (ie, palate, anterior wall, medial wall) must be specified. For any maxillectomy, the access used should be listed, and the surgeon should indicate whether the maxillectomy has been extended to include adjacent structures. © 1997 John Wiley & Sons, Inc.

Background: Thisstudywas conducted to evaluate quality of life in patients treated with primary radiotherapy (RT) for cancer of the base of tongue. Methods: From 1981 to 1990, 36 patients with primary squaradiotherapy. Ages ranged from 35 to 71 years (median, 58 years). T Stage was: T1, n = 11; T2, n = 14; T3, n = 10; T4, n = 1. Thirty-one patients (86%) had palpable cervical lymph node metastases at initial examination (N1, n = 16; N2, n = 11; N3, n = 4). Patients received external beam RT to their primary site and necks, followed by a brachytherapy boost to the tongue. Those with neck nodes also had a neck dissection. The median follow-up is 5 years (minimum, 3 years). Actuarial 5-year local control was 85%; regional control was 96%; distant metastases-free survival was 87.5%; and overall survival, 85%. Twenty-nine of the 30 long-term survivors completed (1) Memorial Symptom Assessment Scale (MSAS), (2) Functional Assessment of Cancer Therapy (FACT), (3) Performance Status Scale for Head and Neck Cancer(PSS), and (4) a sociodemographic and economic questionnaire. At the time of cancer diagnosis, 62% were employed full-time, and 21% were employed part-time; 83% were earning >$20,000/year, and 59% were earning >$60,000/year. Results: At follow-up, annual incomes were similar to those at initial examination. Of those who had been working full-time, 72% were still in full-time work, and of those who had been working part-time, 83% were still in part-time work. Average PSS scores were 90 for eating in public, 96 for understandability of speech, and 68 for normalcy of diet. On the MSAS, the following symptoms had prevalence: >30% xerostomia, difficulty swallowing, decreased energy, pain, worrying, insomnia, cough, drowsy, change In taste, and irritability. Scores on the FACT exceeded published values collected for a mixed cancer population. Conclusions: The overwhelming majority of patients achieved excellent functional status and quality of life and could maintain their prediagnosis earning potential and employment status after primary radiation for advanced base of tongue cancer.

The radical neck dissection is an operation for the management of lymph node metastases from primary sites involving the oral cavity, larynx, and other areas of the head and neck. In this procedure, the spinal accessory nerve is removed along with other structures. In modified neck dissection the spinal accessory nerve is preserved. Patients undergoing the modified neck dissection have had variable functional outcomes from little or no pain or disability, to significant muscle dysfunction. Our group hypothesized that patients with good functional outcomes following modified neck dissection may have had motor contributions from C2, C3, or C4 branches, while those with less favorable outcomes did not. To demonstrate the presence of motor input and its significance both from the spinal accessory nerve and the branches of the cervical plexus, we utilized intraoperative electroneurography. We find that although there is motor contribution from C2, C3, and C4 to the trapezius muscle, it was not consistent or significant.

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.

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 predictors 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.

Background. Patients with head and neck cancer who continue to smoke after diagnosis and treatment are more likely than patients who quit to experience tumor recurrence and second primary malignancies. Therefore, information about patients' smoking status and the factors associated with continued tobacco use are important considerations in the comprehensive care patients with head and neck cancer. Methods. Study participants were 144 patients with newly diagnosed squamous cell carcinomas of the upper aerodigestive tract who underwent surgical treatment, with or without postoperative radiotherapy or chemotherapy, 3-15 months before assessment of their postoperative tobacco use. Results. Among the 74 patients who had smoked in the year before diagnosis, 35% reported continued tobacco use after surgery. Compared with patients who abstained from smoking, patients who continued to use tobacco were less likely to have received postoperative radiotherapy, to have had less extensive disease, to have had oral cavity disease, and to have had higher levels of education. Hierarchical regression analysis indicated that most of the explained variance in smoking status could be accounted for on the first step of analysis by disease site. Interest in smoking cessation was high, and most patients made multiple attempts to quit. Conclusions. Although the diagnosis of a tobacco-related malignancy clearly represents a strong catalyst for smoking cessation, a sizable subgroup of patients continue to smoke. Patients with less severe disease who undergo less extensive treatment are particularly at risk for continued tobacco use. These data highlight the importance of developing smoking cessation interventions designed to meet the demographic, disease, treatment, and tobacco-use characteristics of this patient population.

Background: Commencing in 1984, we initiated a head and neck service surgical database that included a classification system for neck dissection. The aim was to reduce the confusion in terminology resulting from growing interest in modifications of conventional radical neck dissection. Methods: We considered a neck dissection as radical when four or five lymph node levels were excised; this included patients who had an otherwise classical neck dissection for supraglottic larynx or hypopharyngeal cancer sparing level 1. Lymph-node levels removed, nonlymphatic structures preserved, and excised non-lymphatic structures not ordinarily included in a classical radical neck dissection were all specified by the operating surgeon. We defined as a selective neck dissection any lymphadenectomy that encompassed no more than three nodal levels, usually supraomohyoid (levels 1, 2, 3), or jugular (levels 2, 3, 4). We defined as a limited neck dissection any lymphadenectomy that involved removal of no more than two nodal levels. Results: At the 10-year mark, this database of 10,650 patients now includes 2,635 lymphadenectomies in 2,426 patients, the precise extent of which is accurately described in each patient. Conclusions: The current classification of neck dissection does not cover all possibilities. If we define as radical those lymphadenectomies that resect four or five nodal levels and specify structures preserved or additional nonlymphatic structures sacrificed, we allow for the possibility that some procedures may be both modified and extended. Selective would describe the standard, three-level dissections (eg, supraomohyoid or jugular node dissections), and the term limited would be introduced to indicate a neck dissection that involves removal of no more than two nodal levels. Such a three-tiered classification would more accurately reflect the time and effort involved and provide a more equitable basis for reimbursement.

Background. Soft tissue sarcomas of the head and neck represent uncommon malignant neoplasms. With the exception of orbital and parameningeal sites, the treatment of sarcomas in the head and neck has not been standardized. The authors used a prospectively collected database of adult soft tissue sarcomas to identify prognostic factors for local control and survival. Methods. A prospectively collected database of adult soft tissue sarcoma from 1982 to 1989 was analyzed for the impact of prognostic factors on local control and survival. Factors examined included histologic type, tumor grade, size, and resection margins. Results. The overall and disease free survival at 5 years was 71 and 60%, respectively. Local control was 70% at 5 years. On univariate analysis, grade and margin status were predictors for local control. Analysis based on the Cox proportional hazard model revealed that margin status was the only significant factor in predicting local control. Grade and margin status were significant prognostic indicators for survival both on univariate analysis and in the Cox proportional hazard model. Conclusion. Patients with head and neck sarcomas should undergo wide excision with the removal of all gross disease and the acquisition of negative, microscopic surgical margins. Patients with positive margins should receive adjuvant radiotherapy for local control. High grade lesions place patients at risk for local recurrence and distant dissemination. Investigational regimens designed to prevent metastatic disease should be performed. Cancer 1994; 74: 697-702.

Between January 1988 and June 1992, 20 patients with unresectable malignant tumors at the skull base were treated. Eleven had T4 lesions of the paranasal sinus/cavity complex, and 9 had T4 nasopharynx cancer. All patients had stage IV disease by the American Joint Committee on Staging Criteria. The histology was squamous cell cancer in 15 patients and other minor salivary gland histologies in 5. There was brain and/or dural invasion in 11 patients and orbital invasion in 9. All patients received radiation therapy with accelerated fractionation to a total of 70 Gy in 6 weeks. Concomitant cisplatin (100 mg/m2) was given on days 1 and 22 of radiation. Seven patients received mitomycin C (7.5 mg/m2) on days 1 and 22, plus adjuvant chemotherapy with cisplatin and vinblastine. Median follow-up was 11 (range: 1 to 43) months. At 2 years, local progression-free survival was 94%, distant metastases-free survival was 57%, and overall survival was 80%. Complications occurred in 20% and caused the death of 1 patient. Treatment of this group of patients with aggressive chemotherapy and radiation therapy produced excellent local control in our early experience, but longer follow-up is needed. There is a high rate of distant failure. Future strategies are outlined.

Background. A consecutive series of 85 patients undergoing craniofacial resection for malignant tumors involving the anterior cranial base between 1974 and 1992 was reviewed. Results. There were two (2%) postoperative deaths. Postoperative complications occurred in 33 (39%) patients. Local major complications occurred in 26 (31%) patients, local minor in 7 (8%), and systemic in 5 (6%). More than one complication occurred in a number of patients. Bacterial contamination led to a significant proportion of local, septic complications. Repair of the skull base defect with a pedicled pericranial flap was unsatisfactory and was associated with an increased incidence of local major complications. A local major complication was associated with a dramatic lengthening of hospitalization. Conclusion. Future endeavors for prevention of complications should focus on antibiotic prophylaxis and reconstruction of the cranial base defect with better vascularized flaps. © 1994 John Wiley & Sons, Inc.

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. In two patients, no motor action potentials were recorded when the cervical plexus was stimulated. The results suggest that motor innervation of the trapezius is variable. The accessory nerve, when present, provides the most important input to the trapezius. Motor innervation from the cervical plexus is unpredictable, although it appears to be present in the majority of patient studies.

Recent studies have confirmed the presence of estrogen and progesterone receptors in many benign and malignant thyroid tumors, but their clinical significance is unclear. The estrogen and progesterone receptor content of 135 thyroid lesions was assayed prospectively from 1980 through 1986 using the dextran-coated charcoal method. The cases included 30 papillary, 13 follicular, 6 medullary, and 2 Hurthle cell carcinomas. Thirty-two follicular adenomas, 45 goiters, and 7 cases of thyroiditis also were studied. Estrogen receptor protein was positive (> or = 2 fmol/mg) in 46% of the cases, with no clear statistical predilection related to the type or size of the thyroid lesion, age, or sex. Progesterone receptor protein was positive (> or = 10 fmol/mg) in 51% of the cases, with the highest median values obtained in papillary carcinomas, particularly in male patients and women older than 50 years. Metastases at presentation, noted in 28 of 51 carcinomas, were unrelated to receptor content. Mean follow-up of 55 months in 48 patients with various carcinomas yielded 12 cases with late metastases, which were similarly unrelated to receptor content. Although estrogen receptors are commonly detectable in thyroid lesions, they have no clear relationship to presenting clinical or pathologic features or, in cases of carcinoma, to subsequent metastatic potential. The role of progesterone activity in papillary carcinoma and in goiter merits more investigation.

Carcinosarcomas of the salivary glands are rare lesions that generally have been associated with benign mixed tumors. The authors report a case of a submandibular gland lesion, which occurred in a 64-year-old man, that was composed of intermingled ductal type adenocarcinoma and osteogenic sarcoma with a large component of osteoclast-like giant cells. The local recurrence of the tumor was entirely sarcomatous with no epithelial component observed. There was no histologic evidence of a preexisting or coexisting pleomorphic adenoma. Immunohistochemical studies confirmed two separate populations of tumor cells, corresponding to the histologic growth pattern. The authors review the literature and discuss histogenetic implications of distinction between de novo carcinosarcoma and carcinosarcoma in association with pleomorphic adenoma.

A consecutive series of 71 patients who underwent craniofacial resection between 1974 and 1990 for tumors that involved the anterior cranial base was reviewed. A variety of histologic diagnoses was present in this series. The most prevalent sites of origin included the nasal cavity, ethmoid sinus, and frontal sinus. Gross tumor removal was achieved in all patients, with 29 requiring orbital exenteration. Adjuvant radiation therapy was used in 25 patients. Two patients died of postoperative complications and 26 had complications that increased morbidity and length of the hospitalization. Five-year overall survival was 56%, with a median survival of 4.2 years. Local control was observed in 40 of 56 patients with negative margins and 9 of 15 patients with positive margins. There was no difference in survival between previously treated and untreated patients. Survival varied considerably among the various pathologic diagnoses. Survival was related to the extent of disease. Patients with either dural or brain invasion had significantly decreased survival compared to those with no dural invasion. The operative procedure is safe, with acceptable morbidity and mortality, and offers respectable survival in properly selected patients.

To define the indications for elective neck treatment, the cases of 474 previously untreated patients were reviewed who had locally confined major salivary gland cancers treated between 1939 and 1982. Clinically positive nodes were present in 14% (67 of 474). Overall, clinically occult, pathologically positive nodes occurred in 12% (47 of 407). By univariate analysis, several factors appeared to predict the risk of occult metastases; however, multivariate analysis revealed that only size and grade were significant risk factors. Tumors 4 cm or more in size had a 20% (32 of 164) risk of occult metastases compared with a 4% (nine of 220) risk for smaller tumors (P less than 0.00001). High-grade tumors (regardless of histologic type) had a 49% (29 of 59) risk of occult metastases compared with a 7% (15 of 221) risk for intermediate-grade or low-grade tumors (P less than 0.00001). In view of the low frequency of occult metastases in the entire group, routine elective treatment of the neck is not recommended. High-grade tumors and larger tumors have a high rate of occult neck metastases, and treatment should be considered in this group.

We reviewed our experience with 120 patients who had gastrointestinal (GI) continuity restored by gastric transposition after cervical esophagectomy or circumferential pharyngectomy. This included 62 patients with pharyngeal tumors, 43 with esophageal lesions, 7 with parastomal recurrences, and 8 with other primaries (including 4 with thyroid cancer). Operative mortality (11%) for this two-team procedure was significantly higher in patients 60 years of age or older, and there was a trend toward higher mortality in those who had resection of esophageal rather than pharyngeal primaries (14% versus 5%). A total of 105 intraoperative or perioperative complications occurred in 66 patients (55%), 81 of which were directly related to the surgery and 24 of which involved various organ systems. Aside from 15 anastomotic leaks (13%) and 3 instances of partial stomach necrosis (3%), most of the local complications were relatively minor. Our experience indicates that the transposed stomach is highly reliable for restoration of GI continuity, but complications are frequent and the mortality is high. Careful patient selection is essential to minimize morbidity.

In an attempt to define the natural history and the indications for postoperative radiotherapy (RT) in locally recurrent major salivary gland cancers, we reviewed 78 patients treated between 1965 and 1982. All patients underwent resection of the tumor. Group 1 (N = 38) had complete resection of tumors, with low or intermediate grade histology and without lymph node spread. Group 2 consisted of the remaining 40 patients who had high-risk features (HR) (high grade histology, lymph node metastases, and close or positive margins of resection). Half of the Group 2 patients received radiation therapy. Overall survival was 63% at 5 years, and 35% at 15 years. Survival of Group 1 was 83% at 5 years and 58% at 15 years. Local control for Group 1 was 69% at 5 years, 54% at 15 years, and was size-dependent. Group 2 survival was 40% at 5 years and 29% at 10 years. Local control at 5 and 10 years was 49% and 35%. Our data indicate that surgery alone yielded good local control in patients with small tumors (less than or equal to 3 cm) and no HR features, suggesting that postoperative RT may be unnecessary for these patients. Other patients have suboptimal local control, and although there is a rationale for the use of postoperative radiotherapy, we cannot assess its impact in this retrospective study.

Between January 1975 and December 1980, 111 patients with AJCC stages III and IV squamous cell carcinoma of the head and neck were treated with surgery followed by planned postoperative radiation therapy. A previous analysis of a subgroup of these patients showed that, when radiation was delayed more than 6 weeks from surgery, a higher incidence of regional failure occurred compared with the incidence observed when therapy began within a 6 week period. We have looked back at this group of patients plus others in an attempt to determine whether other factors played a role in the results obtained. In the current study, 50 patients had a delay of 6 weeks or more and, of these, 11 (22%) suffered a locoregional recurrence. However, 8 of these 11 patients received suboptimal radiation doses (less than 56 Gy) for permanent control of the disease. In fact, of 17 patients who received at least 60 Gy and had more than a 6 week delay, only 2 (12%) had locoregional failure. This was similar to the incidence of failure in the patients who received at least 60 Gy and who started radiation within the first 6 weeks from surgery (3/20 [15%]). The effect of delay was apparent only in those who received less than 60 Gy (27% vs. 7%, P less than 0.05). Therefore, we cannot validate the previous conclusion that a greater than 6 week delay in the delivery of postoperative radiation therapy in advanced head and neck cancers produces poorer results. The current analysis suggests that a prolonged delay in postoperative radiation therapy in itself does not have a negative impact on locoregional control as long as appropriate tumorcidal doses of more than 60 Gy are employed.

Objectives: To review our experience with craniofacial resection for malignant neoplasms of the anterior skull base and report long-term results, and to analyze survival in terms of the overall experience, tumor histological diagnoses, and tumor extent. Also, to report complications of this surgical procedure. Design: Retrospective review. Setting: Tertiary cancer facility. Patients: We evaluated 115 consecutive patients undergoing craniofacial resection for malignant neoplasms involving the anterior skull base. Forty-five (39%) presented with recurrent or persistent disease after prior therapy. Main Outcome Measures: Survival was evaluated with the Kaplan-Meier product limit method and comparisons between individual subgroups were performed using the log-rank test. Results: The operative mortality rate was 3.5%. Major complications occurred in 40 patients (35%). For the entire group, disease-specific survival rates were 58% and 48% at 5 and 10 years, respectively. The highest survival rate was observed in patients with esthesioneuroblastoma and lowest in those with mucosal melanoma. Survival was significantly better for those whose tumors could be excised with a limited resection in comparison with those requiring an extended procedure ( P =.009). Conclusions: A 23-year experience with craniofacial resection performed for malignant tumors involving the anterior skull base confirms the durable results obtained with this intervention. The diversity of histological diagnoses, site of origin, extent of tumor invasion, and impact of prior therapy hampers any attempt at reporting meaningful survival statistics for comparison with other series or other means of treatment.

objective To review our experience with anterior craniofacial resection for malignant neoplasms with intracranial extension. Survival was analyzed in terms of presence of intracranial extension, extent of intradural disease, tumor histology, and histological status of margins. patients In a retrospective review made at a tertiary cancer facility, 26 of the 115 consecutive patients undergoing craniofacial resection for malignant lesions of the anterior skull base had intracranial extension, defined as durai and/or brain extension. Survival was evaluated with the Kaplan-Meier product limit method, and comparisons between individual subgroups were performed using the log-rank test. results Patients with intradural extension have a statistically worse disease-specific survival than patients without intracranial extension ( P = 0.05). Surgical margins and tumor histology impact on survival. The incidence of local complications was 42% and of systemic complications, 8%. conclusion Anterior craniofacial resection is indicated for patients with resectable disease. The complication rate is comparable with that of patients without intracranial extension. Gross total resection with histologically negative margins portends a better prognosis. Esthesioneuroblastoma has a better prognosis than other tumor types.

Purpose : Minimal literature exists with 10-year data on neck control in advanced head and neck cancer. The purpose of this study is to determine long-term regional control for base of tongue carcinoma patients treated with primary radiation therapy plus neck dissection. Methods and Materials : Between 1981–1996, primary radiation therapy was used to treat 68 patients with squamous cell carcinoma of the base of tongue. Neck dissection was added for those who presented with palpable lymph node metastases. The T-stage distribution was T1, 17; T2, 32; T3, 17; and T4, 2. The N-stage distribution was N0, 10; N1, 24; N2a, 6; N2b, 11, N2c, 8; N3, 7; and Nx, 2. Ages ranged from 35 to 77 (median 55 years) among the 59 males and nine females. Therapy generally consisted of initial external beam irradiation to the primary site (54 Gy) and neck (50 Gy). Clinically positive necks were boosted to 60 Gy with external beam irradiation. Three weeks later, the base of tongue was boosted with an Ir-192 interstitial implant (20–30 Gy). A neck dissection was done at the same anesthesia for those who presented with clinically positive necks, even if a complete clinical neck response was achieved with external beam irradiation. Neoadjuvant cisplatin-based chemotherapy was administered to nine patients who would have required a total laryngectomy if their primary tumors had been surgically managed. The median follow-up was 36 months with a ranged from 1 to 151 months. Eleven patients were followed for over 8 years. No patients were lost to follow-up. Results : Actuarial 5- and 10-year neck control was 96% overall, 86% after radiation alone, and 100 after radiation plus neck dissection. Pathologically negative neck specimens were observed in 70% of necks dissected after external beam irradiation. The remaining 30% of dissected necks were pathologically positive. These specimens contained multiple positive nodes in 83% despite a 56% overall complete clinical neck response rate to irradiation. Regional failure occurred in only two patients, neither of whom underwent adjuvant neck dissection. Symptomatic neck fibrosis (RTOG grade 3) was not observed. Actuarial 5- and 10-year local control was 88% and 88%, disease-free survival was 80% and 67%, and overall survival was 86% and 52%. Conclusion : For base of tongue cancer, most patients can obtain long-term regional control with no severe complications after definitive radiation therapy, plus neck dissection for those who present with lymphadenopathy. Complete clinical regression of palpable neck metastases after irradiation poorly correlates with pathologic outcome. Our current policy is to include neck dissection at the time of implantation for patients who present with palpable neck metastases. We realize that this therapeutic approach may overtreat some patients, but we are reluctant to change our policy in light of these excellent outcomes.

Background Supraomohyoid neck dissection (SOHND) has assumed increasing importance as a staging lymphadenectomy in patients with N 0 oral and oropharyngeal squamous cell carcinoma (SCC), as well as a potentially curative procedure in selected patients with limited metastatic disease in the neck. Methods Retrospective chart review of 287 patients who had a total of 320 SOHND for SCC between 1986 and 1993 as a follow-up to an earlier report that covered our experience between 1980 and 1985. After excluding 24 patients who also had local recurrence, or a new primary, the remaining 296 SOHND were assessed for the effectiveness of tumor control in the neck. Results Of 248 elective SOHND, clinically negative nodes proved histologically positive in 60 patients (25%), only 4 of whom failed in the neck (7%). A total of 48 patients (16%) had a therapeutic SOHND for limited N+ disease, confirmed pathologically in 31, with neck recurrence documented in 2 (6%). N 0 des proved negative histologically in 205 patients, 10 of whom failed in the neck (5%). Nine of the 16 patients with neck recurrence had received postoperative radiation therapy and 9 recurred within the field of the SOHND. Conclusions SOHND is a reliable staging procedure in patients with N 0 oral or oropharyngeal SCC. Therapeutic SOHND, in conjunction with postoperative radiation therapy, was highly effective in controlling neck metastases in carefully selected patients with limited disease in the upper neck.

Background Some patients undergoing surgical resection of primary squamous cell carcinoma of the oral cavity and oropharynx also undergo supraomohyoid neck dissection for staging of the negative (N 0 ) neck. Dissection of the supraspinal accessory lymph node pad requires significant traction of the spinal accessory nerve. There are currently no data to indicate the incidence of metastases to this site and thus the necessity of performing dissection of these nodes. Methods A prospective analysis of a consecutive series of 44 patients with newly diagnosed squamous carcinoma of the oral cavity or oropharynx undergoing surgical management of the primary lesion with staging neck dissection was performed. Patients underwent unilateral (41) or bilateral (3) supraomohyoid neck dissection with separate submission of the supraspinal accessory lymph node pad for pathologic evaluation to determine the incidence of nodal metastases. Results A total of 15 patients (32%) had microscopic metastatic squamous cell carcinoma involving the supraomohyoid neck dissection specimen. Only 1 patient had a metastatic deposit involving the supraspinal accessory lymph node pad. This patient also had metastases in additional lymph nodes at level II. There was an equal incidence of metastases for all patients when stratifying by T stage. Conclusion This preliminary report reveals a small incidence of supraspinal accessory lymph node metastases in patients with T + NO squamous cell carcinoma of the oral cavity and oropharynx. We continue to accrue patients to determine if the incidence of supraspinal accessory lymph node metastases varies with an increased number of patients.

Background Although long-term cures have been achieved for locally advanced squamous cell carcinomas of the head and neck, there is a paucity of information available regarding patients' perspectives of their functional outcome. Patients and methods Thirty-five long-term survivors free of disease following surgery and postoperative radiotherapy for advanced cancers of the oral cavity and oropharynx were sent questionnaires to evaluate their long-term functional outcome after therapy. The questionnaires included a subjective performance status scale that assessed the patient's perceived (1) ability to eat in public, (2) understandability of speech, and (3) normalcy of diet. Twenty-nine of 35 patients participated in this function assessment and are the subjects of this report. Results The mean function scores for all patients were as follows: 72 for eating in public, 69 for understandability of speech, and 58 for normalcy of diet. Functional results were further analyzed by T stage and anatomic subsite. Inferior results were noted with increasing T stage. A two-way analysis of variance showed that this difference was significant even after adjusting for the effect of anatomic subsite ( P = 0.0002, P = 0.018, and P = 0.0018 for the three outcome variables). In addition, patients with base of tongue lesions had a worse functional outcome for both early T stage (T1/T2) and advanced T stage (T3/T4) when compared to other subsites. This difference averaged across T stage was statistically significant for understandability of speech ( P = 0.0019) and normalcy of diet ( P = 0.013), but was not significant for eating in public ( P = 0.16). Conclusions This performance status scale was found to be a useful tool for functional assessment following definitive therapy for advanced stage head and neck carcinomas. These subjective functional scores deteriorated with increasing T stage. In addition, functional scores for oral tongue, floor of mouth, and tonsillar primaries were superior to those for base of tongue lesions. These functional outcome scores are consistent with the extent of surgery required for the base of tongue subsite and are in direct relation to the patients' T stage in this study population.

From 1983 to 1991,31 patients underwent salvage laryngectomy for persistent or recurrent squamous carcinoma of the larynx (14), hypopharynx (15), or oropharynx (2) as part of a larynx preservation protocol. Laryngectomy was performed as a consequence of poor response to induction chemotherapy in 13 and for recurrent disease after completion of chemotherapy and irradiation in 18. Postoperative pharyngocutaneous fistula occurred in 39%, resulting in prolonged hospitalization. Local control was achieved in 68%, more often in patients with laryngeal as opposed to nonlaryngeal primaries (86% versus 53%; p = .05). The overall actuarial survival and disease-specific survival at 2 years were 32% and 38%, respectively. Disease-specific survival at 2 years was better in patients with laryngeal as compared to nonlaryngeal primaries (56% versus 24%; p = .02). There were no long-term survivors among the nonlaryngeal primary patients. In selected patients in whom larynx preservation failed, salvage laryngectomy was associated with acceptable local control and survival. Palliation was obtained in patients who were not cured by their laryngectomy. Future investigation will focus on identification of factors predicting complications and strategies to reduce the incidence and severity.

Twenty-five untreated patients with advanced, resectable squamous cell carcinoma of the hypopharynx, for whom standard treatment would have required total laryngectomy, were treated with one to three cycles of cisplatin-based chemotherapy with larynx preservation as the goal. Patients with a major (complete or partial) response to chemotherapy at the primary site were treated with definitive radiation therapy, with total laryngectomy reserved for salvage; patients with less than a partial response to chemotherapy had total laryngectomy and postoperative radiation therapy recommended. Four patients had a poor response to chemotherapy and thus were not candidates for laryngectomy. Total laryngectomy was required for initial induction chemotherapy failure in five patients and for local recurrence in five others. Three additional patients had unresectable recurrence. Successful larynx preservation was achieved in 32% (8 of 25). With a median follow-up period of 41 months, the actuarial overall and failure-free 2-year survival rates were 44% and 32%, respectively. These preliminary data suggest larynx preservation is feasible in patients with advanced lesions of the hypopharynx. Improved local and regional control must be incorporated into the larynx preservation approach for hypopharyngeal lesions. A prospective, randomized study is necessary for a more valid comparison with conventional therapy, including comparative assessments of survival, morbidity, cost and functional results.

Objective: To evaluate the activity and toxicity of the drug combination cisplatin, fluorouracil by continuous infusion, and high-dose oral leucovorin calcium (PFL) as induction chemotherapy in patients with advanced and untreated squamous cell head and neck (SCHN) cancer. Design: Nonrandomized, prospective trial. Setting: Referral center (comprehensive cancer center). Patients: Twenty-two patients with stage III (n=7) and IV (n=15) MO SCHN cancer of the larynx (n=13), hypopharynx (n=7), and oropharynx (n=2) whose standard treatment would have required total laryngectomy. Interventions: Three cycles of PFL were administered prior to local-regional therapy (concomitant cisplatin and radiation and/or neck dissection, with total laryngectomy reserved for nonresponse or relapse). Chemotherapy included cisplatin (100 mg/m2) on day 1 by short intravenous infusion; fluorouracil (800 mg/m2) on days 1 through 5 by continuous infusion; and leucovorin (100 mg) every 4 hours by mouth for 30 doses. The PFL combination was administered every 21 days. Main Outcome Measures: Clinical response to chemotherapy and observed toxic effects during chemotherapy. Results: Five patients were inevaluable for response, with three early deaths (infection in two and sudden death in one), one cerebrovascular accident, and one patient declining further chemotherapy. Of the remaining 17 patients, 10 had a major response to chemotherapy, but in only five patients (29%) was this complete (95% confidence interval, 8% to 51%). Other significant toxic effects included grade 3 to 4 mucositis in eight patients and grade 3 to 4 neutropenia in 10. Conclusions: While PFL is active in patients with SCHN cancer, we were unable to reproduce the high complete response rates reported by other centers. Its use can be associated with significant toxic effects. We do not recommend the use of PFL for the treatment of patients with SCHN cancer outside the context of a clinical trial until there is further critical assessment of its activity and toxicity.

The extent of surgical resection for differentiated carcinoma of the thyroid gland confined to one lobe remains controversial. Although primary tumor size and extrathyroid extension are associated with a poor prognosis, the presence of multifocal lesions is not associated with an adverse prognosis. Therefore, the role of lobectomy versus total thyroidectomy must be studied in a prospective, randomized trial. Due to the need for long-term follow-up, such a trial has not yet been undertaken. As an alternative to such a trial, we have identified 146 patients from a consecutive series of 931 previously untreated patients undergoing surgical treatment at 1 institution between 1930 and 1980. For this study of matched-pair analysis, 73 patients, aged 45 years or older, were matched in each arm for significant prognostic factors. One group underwent lobectomy, and the other group underwent total thyroidectomy. The 20-year survival rate in the lobectomy group was 82% compared with 73% in the total thyroidectomy group (p = not significant). The patterns of failure in these two groups of patients were examined. A comparison of the patients who underwent lobectomy with an unmatched group of patients who underwent lobectomy showed similar survival rates. On the other hand, unmatched patients undergoing total thyroidectomy had a poorer survival rate than the matched group. This signifies a more aggressive nature of disease in the unmatched group of patients undergoing total thyroidectomy. We therefore conclude that low-risk patients undergoing lobectomy are likely to do as well as those undergoing total thyroidectomy and without the increased risk of the morbidity of total thyroidectomy.

The presence of a positive or close margin after resection of a squamous cancer of the head and neck is associated with a significant risk of local recurrence. To determine the efficacy of postoperative radiation therapy for patients with advanced oral cavity and oropharyngeal cancers with inadequate margins of resection, the present retrospective analysis was undertaken.One hundred and two patients were treated with surgery and postoperative radiation therapy for advanced squamous cell carcinomas of the oral cavity and oropharynx. The anatomic subsites treated include oral tongue (n = 29), floor of mouth (n = 22), base of tongue (n = 31) and tonsillar fossa (n = 20). Twenty-five patients (25%) had positive margins, 41 patients (40%) had close margins (or = 0.5 cm from the surgical margin) and 36 (35%) had negative margins. The median radiation dose was 6000 cGy.With a median follow-up of 7 years, the actuarial control rate for patients with positive, close and negative margins was 79%, 71%, and 79%, respectively. When postoperative doses ofor = 60 Gy were delivered to patients with positive/close margins (excluding patients with oral tongue lesions), the 7-year actuarial control was 92%. In similar patients receiving60 Gy, the actuarial control was 44% (p = 0.0007). Compared to other anatomic subsites, inferior control rates were obtained with oral tongue lesions. For this subsite, the control rates for positive, close, and negative margins were 50%, 62% and 69% respectively.We conclude that excellent local control can be achieved with postoperative radiation therapy, despite the presence of inadequate margins of resection, when doses ofor = 60 Gy are used. Future strategies must be directed at further improving these results in patients with oral tongue lesions.

A retrospective review of a consecutive series of 931 previously untreated patients with differentiated thyroid carcinoma treated over a 50-year period was undertaken to analyze prognostic factors. Data pertaining to demographic status, clinical, operative, and pathologic findings, and survival were analyzed. Univariate statistical analysis was performed based on the Kaplan-Meier method and the log-rank test. Multivariate analysis was performed to assess the independent effect of these variables using the Cox model. There were 630 female and 301 male patients, with an average age of 43 years. A total of 532 patients were younger than 45 years. Seven hundred thirty-one patients had either pure or mixed papillary carcinoma, and 200 had follicular carcinoma. In 153 patients, lesions were larger than 4 cm. Extrathyroidal extension was noted in 71 patients. Multifocal lesions were present in 159 patients. Regional lymph node metastasis was present on admission in 451 patients, and distant metastases were noted on presentation in 45 patients. Determinate survival for all patients was 87% at 10 years. Favorable prognostic factors using univariate analysis included female gender, multifocal primary tumors, and regional lymph node metastases. Adverse prognostic factors included age over 45 years, follicular histology, extrathyroidal extension, tumor size exceeding 4 cm, and the presence of distant metastases. On multivariate analysis, the only factors that affected the prognosis were patient age, histology, tumor size, extrathyroidal extension, and distant metastaces. These observations support findings of reports from the Mayo Clinic and Lahey Clinic regarding the significance of prognostic factors for differentiated carcinoma of the thyroid gland.

We reviewed a 45-year experience with 459 patients who had previously untreated minor salivary gland neoplasms, 378 (82%) of which were malignant. Data were adequate for retrospective clinical staging in 353 of the 378 patients with malignant tumors using criteria identical to those for squamous carcinoma in the same sites. Five-, 10-, and 15-year survival rates for the patients with malignant tumors treated after 1966 were 75%, 62%, and 56%, respectively, a significant improvement compared with results reported previously. Multivariate analysis confirms that survival was significantly influenced by the clinical stage and the histologic grade, but the applicability of grading was limited to patients with mucoepidermoid carcinoma or adenocarcinoma. Ten-year overall survival was 83%, 53%, 35%, and 24% for patients with stage I through stage IV, respectively. Results in these patients are similar to those we have recently reported in patients with major salivary gland carcinomas, but we are unable to demonstrate that postoperative radiotherapy improved survival.

In January 1988, we initiated a prospective study evaluating a new treatment approach with chemotherapy and radiotherapy for unresectable head and neck cancer. Weeks 1-4 were the initial debulking phase. Radiotherapy was delivered using 1.8 Gy/day to large portals including gross disease and all areas at risk. Cisplatinum, 100mg/m2, was given concomitant with radiotherapy on days 1 and 22. Weeks 5 and 6 were the boosting phase. This involved twice-a-day irradiation. The AM fraction of 1.8 Gy was given to the entire area at risk, whereas the PM dose of 1.6 Gy was limited to the gross disease alone. Thus a total of 70 Gy/6 weeks was delivered. A total of 24 patients were treated, 22 of whom have completed this protocol and are evaluable. All patients had massive disease, with 15 having gross involvement of brain, orbit, skull base, or carotid artery. Follow-up ranged from 3-22 months (median 12 months). Major responses were achieved in 96%, with 64% complete responses and 32% partial responses. Two patients with PR were able to undergo complete surgical resection, making the overall rate of complete response, including surgery, 73%. At 1 year, actuarial survival was 69%, and local progression-free survival was 56%. Distant metastases developed in 5 (23%). This approach appears both safe and effective in producing excellent regression and local control for far advanced head and neck cancer. More time is needed to see if these results are sustained. Efforts to build upon this experience appear warranted.

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)

We reviewed the clinical records and pathologic material of 176 adults with primary soft tissue sarcomas treated at Memorial Sloan-Kettering Cancer Center between 1950 and 1985. Seventy-two patients (41%) had low-grade sarcomas and 104 (59%) had high-grade sarcomas. All but 18 patients underwent some form of excision as initial therapy. Adjuvant radiotherapy and chemotherapy combined with surgical excision showed no significant effect. A significantly increased risk of treatment failure was associated with large tumor size, positive surgical margins, bone involvement, local recurrence, metastatic spread, and high histologic grade. Except for recurrence, the p value by univariate analysis in the log-rank test for comparison of survival according to these clinical and pathologic characteristics was p less than 0.0001. Although the overall survival was 75% at 2 years, 55% at 5 years, and 46% at 10 years, only 20% of the patients with high-grade sarcomas were alive 10 years after treatment. Most patients with rhabdomyosarcoma, high-grade peripheral nerve tumor, and high-grade fibrous histiocytoma and all patients with high-grade angiosarcoma died of disease less than 5 years after diagnosis. New therapeutic strategies are needed to improve the survival of adult patients with high-grade soft tissue sarcomas of the head and neck.

We have reviewed a 12-year experience with 295 patients treated for squamous carcinoma of the pharynx in order to focus on 78 patients whose lesions arose in the posterior wall. Surgery was the definitive therapy for the primary tumor in 57 (73%), including 3 treatment groups. Thirty-two patients had limited resections that preserved the larynx, involving local excision (7 patients), anterior pharyngotomy (7 patients), lateral pharyngotomy (6 patients), median labiomandibular glossotomy (6 patients), or median mandibulotomy with paralingual extension (6 patients). The second group consisted of 21 patients with more extensive tumors who required a laryngectomy and complex reconstruction, often with postoperative radiotherapy. Finally, there were four patients who developed metachronous second primaries in the pharynx subsequent to a laryngectomy. All required flap reconstruction. Of the 21 patients whose primary treatment was radiotherapy, 5 had lesions that were implanted after access was provided by a mandibulotomy. Cumulative 5-year survival was 32% and ranged from 44% in those with favorable lesions to 15% in those with extensive tumors. Our experience highlights the variety of treated approaches available in patients with pharyngeal carcinomas confined to the posterior wall. Surgery in this setting carries acceptable morbidity and yields survival rates that compare favorably with those achieved by external radiation therapy alone. Results in patients with extensive lesions still leave much, to be desired, despite radical, surgery and aggressive radiotherapy. Innovative branchytherapy techniques using surgery for access deserve further investigation.

Three hundred ninety-eight consecutive, previously untreated patients undergoing surgery for epidermoid carcinoma of the oral cavity from 1979 to 1983 were reviewed. One hundred twenty-nine patients were classified as having positive surgical margins. Of these, 83 patients had tumor within 0.5 mm of the surgical margin, 9 had premalignant changes at the margin, 9 had in situ carcinoma at the margin, and 28 had invasive cancer at the margin. The remaining 269 patients had uninvolved margins. The significance of positive margins relating to survival, subsequent clinical course, local recurrence, and patterns of treatment failure was examined, along with the impact of adjuvant postoperative radiotherapy on positive margins. The percentage of patients having positive margins progressively increased with increasing T stage: 21% in T1 versus 55% in T4 primary cancers. The overall 5-year survival for patients with negative margins was 60%. For patients with positive margins, 5-year survival was 52%. This difference was statistically significant. The incidence of local recurrence in patients having positive surgical margins was twice as much as in those with negative margins (36% versus 18%). Metastasis rates in the neck and at distant sites were not significantly influenced by the status of the surgical margin. Of the 129 patients with positive margins, 49 received postoperative radiotherapy. In those patients so treated, a trend toward lower recurrence rates was noted. Differences were not statistically significant. This retrospective review confirms the importance of adequate resection of the primary tumor as well as the relative ineffectiveness of adjuvant postoperative radiotherapy in the improvement of local control in patients with positive surgical margins.

Between 1966 and 1982 there have been 46 patients treated with surgery plus post-operative radiation therapy for malignant tumors of salivary gland origin. The indication(s) for radiotherapy included positive margins (42%), advanced local tumor (37%), positive nodes (33%), or high grade histology (48%). Overall actuarial local control at 5 years was 73%, being 100% for T1, 83% for T2, 80% for T3, and 43% for T4. Actuarial survival at 5 years was 80% for T1, 83% for T2, 60% for T3, and 48% for T4. Patients with positive nodes (N+) did worse than those with negative nodes (No), with locoregional control and survival at 5 years being 58% vs. 83%, (P = 0.025) and 38% vs. 80% (P = less than .01), respectively. We found no need for contralateral neck treatment even for those with positive nodes. Also, to date, none of eight patients with adenoid cystic histology has failed locally, as opposed to three of eight failures in patients treated with surgery alone. We believe that post-operative irradiation provides excellent locoregional control for appropriate patients with malignant tumors of major salivary glands.

Over a recent 4-year period, 823 neck dissections that included the lower jugular lymph nodes were performed. Of the 823, 14 (1.9%) patients developed chyle fistulas. Two other patients developed fistulas, one after undergoing a gastric transposition, and the other after a scalene node biopsy. All 16 patients were initially managed conservatively with closed-wound drainage and low-fat nutritional support; this was successful in only 4 patients, 3 of whom had peak 24-hour chyle drainage of less than 600 cc. The remaining 10 patients required open-wound management, which included operative ligation in 4 instances. Continued conservative treatment with an open neck wound resulted in significant additional hospitalization. Our experience indicates that closed-wound management of a chyle fistula is likely to fail when peak 24-hour fistula output exceeds 600 cc. Considering the cost and morbidity of conservative treatment, early reoperation may be appropriate in those patients with high fistula output.

• Between 1966 and 1982, 46 patients with previously untreated malignant tumors of major salivary gland origin received combined surgery and postoperative radiotherapy. They were compared with 46 patients treated with surgery only between 1939 and 1965, who were matched according to prognostic criteria. Radiation doses ranged from 4000 to 7740 cGy (median, 5664 cGy). The 5-year determinate survival rates for patients given combined therapy with stage I and II disease vs patients given surgery only was 81.9% vs 95.8%, while for stages III and IV it was 51.2% vs 9.5%, respectively. Local control for stage III and IV disease in patients given combined therapy vs patients given surgery only at 5 years was 51.3% vs 16.8%. For patients with nodal metastases, 5-year determinate survival for the combined-therapy group vs the surgery-only group was 48.9% vs 18.7%, and the corresponding local-regional control was 69.1% vs 40.2%. The results of this analysis suggest that postoperative radiotherapy significantly improves outcome for patients with stage III and IV disease and for patients with lymph node metastases.
