Abstract
Irradiation plays an important role in the treatment of cancers of the head and neck providing a high locoregional tumor control and preservation of organ functions. External beam irradiation (EBI) results in unnecessary radiation exposure of the surrounding normal tissues increasing the incidence of side effects (xerostomy, osteoradionecrosis, and so forth). Brachytherapy (BT) seems to be the best choice for dose escalation over a short treatment period and for minimizing radiation-related normal tissue damage due to the rapid dose falloff around the source. Low-dose-rate BT is being increasingly replaced by pulsed-dose-rate and high-dose-rate BT because the stepping source technology offers the advantage of optimizing dose distribution by varying dwell times. Pulsed-dose and high-dose rates appear to yield local control and complication rates equivalent to those of low-dose rate. BT may be applied alone; but in case of high risk of nodal metastases, it is used together with EBI. This review presents the results and the indications of combined BT and EBI in carcinoma of the base of tongue and other sites of the head and neck region, as well as the role BT plays among other-normal tissue protecting-modern radiotherapy modalities (intensity-modulated radiotherapy, stereotactic radiotherapy) applied in these localizations.

Abstract
Objectives: Squamous cell carcinoma of the tongue base has a poor prognosis, and treatment is accompanied by a number of major problems. In view of this, it is important to recognize which patients will benefit from treatment with curative intent and which treatment method to use. Methods: One hundred sixty-five patients with squamous cell carcinoma of the tongue base were identified on our database. Eighty-two patients were treated by radical irradiation, and 41 by surgery. A further 42 patients were considered unsuitable for curative treatment. Results: The 5-year cause-specific survival rate was 41% for those treated by irradiation, 58% for those treated by surgery, and 9% for untreated patients. There was no difference in the efficacy of treatment methods (p = .5362), but a highly significant difference was seen in survival rate between treated and untreated patients (p = .0028). The decision regarding administration of curative treatment was based on the extent of locoregional involvement at the primary site (p = .0139; odds ratio, 0.43) and in the neck (p = .0078; odds ratio, 0.23). No factors affected the decision to treat by irradiation or surgery. When the observed survival rate was calculated, there was no significant difference in 5-year survival rate between treated and untreated patients (p = .2762). Those with early (T1-2) disease at the primary site had an improved survival rate from 0.5 to 4 years compared with those who were untreated (T3-4; p = .0081; odds ratio, 2.2). In addition, those with early (T1-2) disease had a better survival rate than those with advanced cancers (p = .0139; odds ratio, 2.09). There was, however, no difference in survival rate at 5 years. Those with early disease compared with those with advanced disease were twice as likely to be alive at 2 years; however, all survival advantages had disappeared by 5 years. Conclusions: In terms of observed survival, treating tongue base squamous cell carcinoma that is locally advanced (T3-4) at presentation offers no survival advantage over palliation alone. Treating early disease (T1-2) doubles the survival rate for up to 4 years, but by 5 years this survival advantage is lost. The present study finds radiotherapy and surgery to be equivalent at controlling this disease.

Abstract
CONCLUSION Superselective intra-arterial chemotherapy, which can provide local control and laryngeal preservation, is safe and useful for preserving pharyngeal and laryngeal functions. OBJECTIVE To evaluate superselective intra-arterial chemotherapy in terms of the contribution to survival and laryngeal preservation in squamous cell carcinoma (SCC) of the anterior oropharyngeal wall. METHODS A total of 51 patients with SCC of the anterior oropharyngeal wall received intra-arterial administration of docetaxel at 60 mg/m(2) and cisplatin at 60 mg/m(2) anterogradely, followed by intravenous continuous infusion of 5-fluorouracil at 750 mg/m(2)/day over 120 h starting on day 2. Neck lymph node metastases were treated by neck dissection. RESULTS The 5- and 10-year survival rates of the 51 patients were 72.8% and 66.4%, respectively. The 5-year survival rates of patients with T2, T3, T4a, and T4b cancer were 100%, 88.7%, 41.9%, and 33.3%, respectively. The 5- and 10-year laryngeal preservation rates of the 51 patients were 63.4% and 30.0%, respectively. The 5-year laryngeal preservation rates of patients with T2, T3, T4a, and T4b cancer were 100%, 75.2%, 23.6%, and 33.3%, respectively. No irreversible side effects, complications, or sequelae were reported.

Abstract
Epidemiologic studies have shown a rise in the incidence of oropharyngeal cancer without a corresponding increase in oral cavity cancers. These diverging trends are explained by human papilloma virus, which preferentially affects the oropharynx. Cancers resulting from this viral infection bear a better prognosis than those that are smoking-related. Treatment of oropharyngeal cancers has typically involved the use of radiation and chemotherapy to avoid the morbidity of mandibular splitting surgery. The use of transoral robotic surgery (TORS) has obviated the need for large-scale open approaches but still provides the pathologic staging data that is unavailable from non-surgical approaches. Although TORS is in its infancy, early functional and oncologic outcome data are promising. The complex management of oropharyngeal cancers should utilize the available treatment modalities to optimize outcomes and stratify patients to different treatment based on risk status.

Abstract
PURPOSE To evaluate long time outcome with regard to local tumour control, side effects and quality of life of combined pulsed dose rate (PDR) boost and hyperfractionated accelerated external beam radiotherapy (EBRT) for primary base of tongue (BOT) cancers. MATERIAL AND METHODS Between 1994 and 2007, the number of 83 patients were treated with primary T1-T4 BOT cancers. Seven patients (8%) were T1-2N0 (AJCC stage I-II) and 76 (92%) patients were T1-2N+ or T3-4N0-2 (AJCC stage III-IV). The mean estimated primary tumour volume was 15.4 (1-75) cm3. EBRT was given with 1.7 Gy bid to 40.8 Gy to primary tumour and bilateral neck lymph nodes in 2.5 weeks. PDR boost of 35 Gy and a neck dissection in clinical node positive case was performed 2-3 weeks later. The patients were followed for a median of 54 (2-168) months. RESULTS The 2-, 5- and 10-years rates of actuarial local control were 91%, 89% and 85%, overall survival 85%, 65% and 44%, disease free survival 86%, 80% and 76%, respectively. The regional control rate was 95%. Six patients (7%) developed distant metastases. A dosimetric analysis showed a mean of 100% isodose volume of 58.2 (16.7-134) cm3. In a review of late complications 11 cases of minor (13%) and 5 of major soft tissue necroses (6%), as well as 6 cases of osteoradionecroses (7%) were found. The patients median subjective SOMA/LENT scoring at last follow up was as follow: grade 0 for pain and trismus, grade 1 for dysphagia and taste alteration, and grade 2 for xerostomia. Global visual-analogue-scale (VAS) scoring of quality of life was 8. CONCLUSION Local and regional tumour control rate was excellent in this treatment protocol. The data shows the PDR boost as at least as effective as published continuous low dose rate (CLDR) results.

Abstract
BACKGROUND Our aim was to report the outcomes of base of tongue cancers treated with chemoradiotherapy. METHODS Between 1990 and 2004, 127 patients with stage III or IV base of tongue cancer were treated with chemoradiotherapy on protocol. Indications included nodal involvement, T3/T4 tumors, positive margins, those patients refusing surgery, or were medically inoperable. The most common regimen was paclitaxel (100 mg/m2 on day 1), infusional 5-fluorouracil (600 mg/m2/day × 5 days), hydroxyurea (500 mg prescribed orally [PO] 2 × daily [BID]), and 1.5 Gy twice daily irradiation followed by a 9-day break without treatment. RESULTS Median follow-up was 51 months. The median dose to gross tumor was 72.5 Gy (range, 40-75.5 Gy). Five-year locoregional progression-free survival, overall survival, and disease-free survival was 87.0%, 58.2%, and 46.0%, respectively. CONCLUSION Concurrent chemoradiotherapy results in promising locoregional control for base of tongue cancer. As distant relapse was common, further investigation of systemic therapy with novel agents may be warranted.

Abstract
INTRODUCTION The aim of this retrospective analysis was to analyze the results of conventional radical radiotherapy in the treatment of oropharyngeal cancer and to identify pre-treatment and treatment-related prognostic factors for outcome. MATERIAL AND METHODS The records of 627 patients with oropharyngeal cancer treated with radical radiotherapy with conventional techniques were analyzed. RESULTS The median age was 56 years. History of tobacco abuse was present in 80.5%. Eighty six percent had stage III or IV disease. Radical radiotherapy alone was the treatment modality for 71.2% and concomitant or neoadjuvant chemotherapy was used in 28.8%. The 3-year local control (LC), loco-regional control (LRC), disease-free survival (DFS) and overall survival (OS) was 49%, 40.6%, 38.9% and 36.1% respectively. The 3-year DFS rates were 80.3% for stage I, 65.8% for stage II, 46.1% for stage III and 25.2% for stage IV disease. Multivariate analysis was performed for prognostic factors. Prior history of tobacco abuse was an independent prognostic factor for both DFS and LRC. Karnofsky Performance Score (KPS) < 80, higher nodal stage, lower total radiotherapy dose (<66 Gy) in those receiving > 60 Gy, and overall treatment time > 50 days were other independent prognostic factors for inferior DFS and LRC. KPS < 80, higher T stage, higher nodal stage, RT dose < 66 Gy and longer overall treatment time (>50 days) were independent prognostic factors for poorer local control. CONCLUSIONS Several patient-, disease- and treatment-related variables independently affect survival outcomes after radical radiotherapy for oropharyngeal cancer. Oropharyngeal cancers in those without a history of tobacco abuse may be biologically different and more amenable to cure with radiotherapy.

Abstract
BACKGROUND This study provides the largest contemporary overview of presentation, care, and outcome for base of tongue squamous cell carcinoma (SCC). METHODS We extracted 16,188 cases from the National Cancer Data Base (NCDB). Chi-square analyses were performed on selected cross-tabulations. Observed and disease-specific survival were used to analyze outcome. RESULTS Three-quarters had advanced-stage (III-IV) disease. Radiation therapy alone (24.5%) and combined with surgery (26.9%) were the most common treatments. Five-year observed and disease-specific survival rates were 27.8% and 40.3%, respectively. Poorer survival was significantly associated with older age, low income, and advanced-stage disease. For early-stage disease, surgery with or without irradiation had higher survival than irradiation alone. For advanced-stage disease, surgery with irradiation had the highest survival. CONCLUSIONS Survival rates were low for base of tongue SCC, with most deaths occurring within the first 2 years. Income, stage, and age were significant prognostic factors. In this nonrandomized series, surgery with radiation therapy offered patients with advanced-stage disease the best survival.

Abstract
The management of base of tongue cancer has evolved steadily over time. Organ preservation with primary radiation therapy has produced excellent oncologic and functional outcomes. Concomitant chemotherapy has become important in patients with locoregionally advanced disease. Planned neck dissection after organ preservation therapy continues to be an integral step for regional control. This article reports the results of a literature review of base of tongue cancer emphasizing a multidisciplinary approach to obtain optimal results in terms of cure and quality of life.

Abstract
PURPOSE Low-dose-rate interstitial brachytherapy (LDRIB) represents an effective modality for treatment of oropharyngeal carcinoma. The drawback is radioexposure of medical personnel. To eliminate this concern, we initiated high-dose-rate interstitial brachytherapy (HDRIB) in 1993. The present study evaluated the efficacy and complications associated with this approach. METHODS AND MATERIALS Between 1993 and 2003, HDRIB +/- external radiotherapy was used to treat 83 oropharyngeal squamous cell carcinomas. Median duration of follow-up was 26 months (range, 1-108 months). Of the 82 patients, 76 were previously untreated and 6 displayed previous history of head and neck cancer. T distribution comprised T1 (n = 7), T2 (n = 47), T3 (n = 24), and T4a (n = 5). External radiotherapy of 46 Gy was combined with 21 Gy/3.5 fractions/2 days HDRIB for 68 lesions, and 48 Gy/8 fractions/5 days HDRIB alone was used for 15 lesions. Involved nodes were either boosted by external radiotherapy or resected. RESULTS Five-year local control, regional control, cause-specific and overall survival rates were 82%, 84%, 88%, and 64%, respectively. Local control rates for early (T1/T2) and advanced (T3/T4) tumors were 89% and 66%, respectively (p = 0.02). Transient soft tissue necrosis was experienced in 29% of patients. No bone sequelae were observed in previously untreated patients. CONCLUSIONS High-dose-rate interstitial brachytherapy could achieve excellent local control and acceptable rates of complication, equivalent to reported results for LDRIB series. Given the advantage of radioprotection, HDRIB may replace LDRIB in the treatment of oropharyngeal carcinoma.

Abstract
Major resections of the tongue have not been commonly performed in animals because of concerns about the unfavorable postoperative effects of diminished lingual function. Five dogs were retrospectively reviewed to determine prehensile function and quality of life after glossectomies. Examinations were performed 1 week to 8 years after glossectomy, and owner interviews were conducted 10 months to 8 years after the surgery. All five dogs had acceptable and functional outcomes. Based on these five cases, glossectomy was well tolerated by dogs and may be a viable treatment option for aggressive tongue tumors and other conditions that render the tongue unsalvageable.

Abstract
PURPOSE The outcomes of patients treated at a single institution over a specific time frame using three different therapeutic approaches for cancer of the base of tongue were reviewed. METHODS AND MATERIALS Between 1992 and 1998, 53 patients were treated with curative intent for base of tongue cancer. Seventeen patients underwent surgical resection with postoperative radiation therapy, 16 patients received definitive external radiation therapy only, and 20 patients were treated with external and interstitial radiation, with neck dissection in 16 of those patients. Local control, survival, and functional status were assessed with each approach. RESULTS The 5-year actuarial local control and survival for the surgically treated patients were 74% and 44%, respectively. The patients treated with external radiation therapy alone had local control of 28% and 5-year survival of 24%. The patients treated with external and interstitial radiation with neck dissection as indicated had 5-year actuarial local control of 87% and survival of 33%. Survival was not statistically different between the three treatment approaches (p=0.0995) but local control was worse in the definitive external radiation group (p < 0.0001). Speech and swallowing function among the long-term survivors was superior in the definitively irradiated patients compared with the operated patients. CONCLUSION In this retrospective analysis, survival and local control was lowest in the patients treated with external radiation alone, however, patient selection likely played an important role. Local control was far better with surgical treatment and with external combined with interstitial radiation but survival remains less than 50% with each approach. Surgical treatment was superior for patients with T4 disease. Functional status was higher in the long-term survivors treated nonsurgically.

Abstract
PURPOSE Survival in patients with Stage IV carcinoma of the base of tongue (BOT) treated by surgery and radiotherapy remains poor. External beam radiotherapy (EBRT) and brachytherapy (BT) have been used as an alternative treatment. METHODS AND MATERIALS Eighteen patients with Stage IV carcinoma of the BOT were treated by EBRT and BT. RESULTS Local control is 89%. The 5-year overall (OS) and disease specific survival (DSS) rates are 52% and 67%. No neck node positive patient implanted in the neck developed cervical metastases. Two patients (11%) developed complications. CONCLUSIONS Local regional control, survival, and complications in patients with Stage IV carcinoma of the BOT treated by EBRT and BT have been satisfactory. The use of brachytherapy for nodal metastases has eliminated the need for neck dissection. We recommend this approach in the treatment of Stage IV carcinoma of the BOT.

Abstract
Cancer of the base of the tongue is a challenging disease for the head and neck surgeon, radiation oncologist and medical oncologist. However, over the last 10-15 years, improved treatment strategies have evolved which offer patients high probability of loco-regional control, survival, and good quality of life. The ability to offer patients good oncologic and functional outcomes serves as a paradigm for the successful application of multidisciplinary care, and the emphasis on quality of life in head and neck cancer treatment. This review provides an overview of the treatment options that exist, their advantages and disadvantages, and hopefully provides proper guidelines for the current management of this challenging disease.

Abstract
INTRODUCTION Squamous cell carcinoma (SSC) of the tongue base has historically been shown to be associated with a poor prognosis. We reviewed our experience with primary surgery followed by postoperative radiation therapy (XRT) to determine the impact of our treatment protocols on outcome. METHODS We retrospectively reviewed the records of all patients presenting to the University of Pittsburgh with previously untreated SSC of the tongue base between 1980-1997. Patients who were treated nonoperatively were excluded from analysis. Surgical excision of the primary was performed with ipsilateral neck dissection. The contralateral neck was dissected when the primary lesion was located in the midline or for clinically positive contralateral neck nodes. Postoperatively, most patients (93%) received XRT to the primary site and neck. Adjuvant chemotherapy was offered if histologic signs of aggressive behavior were identified (multiple nodes or extracapsular spread). RESULTS Of 87 patients identified, 39 (45%) were initially seen with T1 or T2 tumors. Seventy-nine patients (91%) were initially seen with stage III or IV disease. Contralateral neck dissection was performed in 36 patients (41%). Metastatic disease was demonstrated in 84% of ipsilateral neck nodes and in 47% of contralateral neck nodes. Occult metastases were found in 61% of clinically N0 necks. Local recurrence occurred in 5 patients, regional recurrence occurred in 12 patients, and distant metastases developed in 22 patients. Overall and disease-specific survival rates at 5 years for all patients were 49% and 56%, respectively. The 5 year disease-specific survival rates for stage I, stage II, stage III, and stage IV disease were 100%, 86%, 62%, and 48%. The 5-year disease-specific survival rate was 88% for T1 lesions, 64% for T2 lesions, 58% for T3 lesions, and 30% for T4 lesions (p <.05, log-rank test). CONCLUSIONS Surgical treatment of SCC of the tongue base is highly effective in achieving local disease control and disease-free survival for early lesions. Because both functional outcome and survival are poor after surgical treatment of advanced lesions, we now offer brachytherapy with XRT or participation in a combined chemoradiation protocol rather than primary surgical therapy to patients with advanced disease. Prospective studies are needed to compare the effect of these organ-preserving therapies with traditional combined surgery and XRT to determine the effect on functional outcome and quality of life.

Abstract
BACKGROUND Surgical resection of tongue base cancer can leave the patient with significant functional deficits. Other therapies, such as external beam radiation followed by neck dissection and radiation implants, have shown equal tumor control with good functional outcome. METHODS Between March 1991 and July 1999, 12 patients at Oregon Health Sciences University, the Portland Veterans Administration Medical Center and West Virginia University School of Medicine Hospital were treated with external beam radiation followed by neck dissection and Ir192 implants. Two patients had T1 disease, two had T2, five patients had T3 tumors, and three had T4 tumors. Six had N2a necks, three had N2b necks, and three had N2c. Follow-up ranged from 13 months to 8 years. RESULTS After external beam radiation, five patients had complete response and seven had partial response in the neck without complications. One patient underwent a unilateral radical neck dissection, eight had unilateral selective neck dissections involving levels I to IV, and three had dissections involving levels I to III. One of the five patients who had a complete clinical response in the neck had pathologically positive nodes. One patient had a pulmonary embolus that was treated and had no permanent sequelae. There were three complications from brachytherapy. Two patients had soft tissue necrosis at the primary site and one patient had radionecrosis of the mandible. All healed without further therapy. One patient had persistent disease and underwent a partial glossectomy but died of local disease. Distant metastasis developed in two patients. All others show no evidence of disease and are able to eat a normal diet by mouth. CONCLUSION This combination of therapies should be considered when treating tongue base cancer.

Abstract
BACKGROUND Early stage squamous cell carcinoma of the base of the tongue has been successfully treated with radiotherapy and brachytherapy. However, the vast majority of these tumours seen in Western Europe are already at an advanced stage. Medical records of 79 patients with squamous cell carcinoma of the base of the tongue treated between 1980 and 1994 were examined. METHODS Eighty-three per cent of the primary tumours were stage T3 or T4. Fifty-nine patients were treated with surgery and post-operative radiotherapy. Quality of life assessment amongst the survivors was performed by means of a questionnaire. RESULTS Five year disease free survival in patients undergoing excision for T3-T4 tumours was 59%. Patients with T2-T3 tumours undergoing partial excision of the tongue base had a 3 year recurrence free survival rate of 68%. Distant metastasis occurred in 16%. Seventy-eight per cent of the patients judged their quality of life to be near normal. CONCLUSION Surgery and post-operative radiotherapy offer a reasonably good survival in advanced carcinoma of the base of the tongue with preservation of quality of life.

Abstract
The treatment of squamous cell carcinoma of the mouth and oropharynx continues to change. In this primary report, we compared the results obtained by combined surgery and radiation therapy, or either modality alone. Other methods such as brachytherapy, or hyperfractionated radiotherapy, were not included in our protocols. A statistical analysis of the 3- and 5-year survival rates in relation to location and size of the primary tumour, stage at initial presentation, treatment modality and recurrence, was carried out in 88 patients with squamous cell carcinoma of the oral cavity or oropharynx. The overall survival rate was 73.8% at 3 years and 66.3% at 5 years. Size of tumour and stage at presentation were significant when P value was adjusted by site. Survival was significantly associated with type of treatment (combined approach obtained superior results), location of primary tumour, and recurrence. The type of neck dissection did not show any effect. Therapeutic modality used, stage, and location of primary tumour significantly influenced survival. A more selective combined initial treatment according to site and stage (distribution) is recommended.

Abstract
PURPOSE To evaluate irradiation alone for treatment of base-of-tongue cancer. PATIENTS AND METHODS Two hundred seventeen patients with squamous cell carcinoma of the base of tongue were treated with radiation alone and had follow-up for >/= 2 years. RESULTS Local control rates at 5 years were as follows: T1, 96%; T2, 91%; T3, 81%; and T4, 38%. Multivariate analysis revealed that T stage (P =.0001) and overall treatment time (P =.0006) significantly influenced local control. The 5-year rates of local-regional control were as follows: I, 100%; II, 100%; III, 83%; IVA, 64%; and IVB, 65%. Multivariate analysis revealed that the following parameters significantly affect the probability of this end point: T stage (P =.0001), overall treatment time (P =.0001), overall stage (P =.0131), and addition of a neck dissection (P =.0021). The rates of absolute and cause-specific survival at 5 years were as follows: I, 50% and 100%; II, 81% and 100%; III, 65% and 76%; IVA, 42% and 56%; and IVB, 44% and 52%. Severe radiation complications developed in eight patients (4%). CONCLUSION The likelihood of cure after external-beam irradiation was related to stage, overall treatment time, and addition of a planned neck dissection. The local-regional control rates and survival rates after radiation therapy were comparable to those after surgery, and the morbidity associated with irradiation was less.

Abstract
BACKGROUND Choice of treatment for base of tongue carcinoma is controversial, with options including surgery alone, radiotherapy alone, or multimodality treatment. Given the highly aggressive nature of these tumors, it has been our institutional policy to manage this disease with combined partial glossectomy (with attempt to avoid laryngectomy if possible) with planned postoperative radiotherapy (RT). We reported on our institutional experience with this approach. METHODS A retrospective review of the charts of 17 patients with primary base of tongue squamous cell carcinoma treated with surgery and postoperative RT was performed. Patients treated with chemotherapy as part of their management were excluded. All patients underwent partial, hemi-, or subtotal glossectomy; 15/17 patients underwent ipsilateral radical or modified radical neck dissection. All patients received comprehensive postoperative RT (median dose 6000 cGy; range 5040-6920 cGy). Stage distribution was as follows: stage I, 2; stage II, 3; stage III, 2; stage IV, 10. Positive margins for invasive carcinoma were found in 9/17 patients. Median follow-up of surviving patients is 46 months; median follow-up for all patients is 31 months. RESULTS For the entire group of patients, the actuarial 3-year local-regional control rate was 68%. The actuarial 3-year overall survival rate was 46%. The local-regional control rate was 83% for patients with stage I-III disease versus 50% for stage IV disease. There were no local failures among eight patients with negative margins (local control 100%) compared with an actuarial local control rate of 36% among patients with positive margins (p = .03). Survival, disease-specific survival, and locoregional control were also highly correlated with margin status (p = .003). Late major complications included 5/17 patients requiring permanent G-tubes and/or tracheostomy to prevent aspiration. CONCLUSIONS Surgery plus postoperative RT is an intensive treatment for carcinoma of the base of tongue which offers high locoregional control in patients in whom negative margins are achieved. Positive margins indicate a high risk of locoregional and systemic failure, and these patients should be considered for innovative clinical trials after surgery.

Abstract
BACKGROUND To define the impact of interstitial boost of the oropharynx on local control and complications using iodine-125 (I-125) brachytherapy. METHODS Between October 1986 and September 1991, 19 patients with cancer of the oropharynx received treatment at William Beaumont Hospital. Primary tumors consisted of 13 base of tongue, 4 tonsillar, and 2 pharyngeal wall lesions. All patients received 45-66 Gy (median, 54 Gy) external beam irradiation to the primary and regional nodes, followed by an interstitial implant of 22-32 Gy (median, 25 Gy) with I-125. RESULTS Median follow-up was 58 months (range, 12-89 months). Three patients failed within the tumor bed, for a 5-year actuarial rate of local control of 83% (T1/T2, 82%; T3/T4, 86%). Two of the three local failures were salvaged surgically, for an overall 5-year actuarial local control rate of 94%. The 5-year actuarial overall survival rate was 64%. Complications included one case of soft tissue ulceration and two cases of osteoradionecrosis, all managed conservatively. CONCLUSIONS Patients with cancer of the oropharynx judged to be candidates for boosts with interstitial implants can be effectively treated with I-125. Local control was excellent, and complications were minimal.

Abstract
In a nationwide survey on oropharyngeal carcinoma in the Netherlands (1986-1990), 380 patients with a tonsillar carcinoma were retrospectively studied. The records of 268 (71%) men and 112 (29%) women with a median age of 59 yr (range 31-91), who had squamous cell carcinoma (272 patients, 98%) or undifferentiated carcinoma (8 patients, 2%) were reviewed with respect to treatment, disease-specific survival and locoregional control. Distribution by stage according to the UICC'92 system was: 27 patients (7%) stage I, 59 (15%) stage II, 99 (26%) stage III, 182 (48%) stage IV and 13 patients (3%) unknown stage. Using a previously reported revised staging system the following distribution was obtained: 118 patients (31%) stage I, 120 (31%) stage II, 67 (18%) stage III, 54 (14%) stage IV and 21 patients (6%) with an unknown stage. Treatment consisted of radiotherapy alone in 231 patients (61%), surgery and radiotherapy in 101 (27%), surgery alone in 30 (8%), chemotherapy in 5 (2%) and 13 patients (3%) did not receive any treatment. At 5-yr the overall survival was 32%, the disease-specific survival 42% and the locoregional control 61%. In patients treated with radiotherapy alone the disease-specific survival was 39%, for surgery and radiotherapy 53% and for surgery alone 83%. The disease-specific survival according to UICC'92 stage was 71% in stage I, 59% in II, 50% in III and 32% in stage IV (P < 0.0001). In the revised staging the survival figures were 63% in stage I, 43% in II, 31% in III and 9% in IV (P < 0.0001). The two staging systems appeared to be comparable in prognostic discrimination; the clinical relevance of the revised stage might, however, be slightly superior to the UICC'92 version. The difference in results after radiotherapy alone and surgery + radiotherapy remained significant, also after adjusting for stage (P < 0.0001).

Abstract
Advanced cancers of the oral cavity continue to be a therapeutic challenge. Despite significant improvements in radiotherapeutic techniques and adjuvant chemotherapy, patients usually die after a short period. Recent progress in reconstructive techniques has made major glossectomy (subtotal, near total, total or extended total) a reasonable palliative and potentially curative approach. It is the purpose of this study to report a series of 106 patients treated from 1985 to 1994 regarding surgical complications and prognosis. All but 1 patient undergoing major glossectomy had squamous cell carcinoma. Primary tumour sites were oral tongue (50 cases), base of the tongue (18 cases), floor of the mouth (28 cases) and other parts of the mouth (10 cases). Tumour stages were: 25 T3, 57 T4, 24 Tx, 34 N0, 20 N1, 32 N2a-N3, 20 Nx. The types of glossectomy were as follows: 24 subtotal, 31 near total and 51 total. A total laryngectomy was performed in only 6 cases. A neck dissection was performed in all but 3 patients: 12 unilateral radical neck dissection (RND), 1 unilateral supra, omohyoid (SOH), 39 simultaneous bilateral RND, 8 simultaneous bilateral SOH, and 43 RND associated to contralateral SOH. A pectoralis major myocutaneous flap was used to repair the operative defect in 96 cases. Complications were seen in 52 cases (49%). The most common complications were wound infection (17 cases), flap necrosis (15 cases) and fistula (15 cases). Significant transient aspiration was seen in 8 patients. At the study closing date, 30 patients were alive without disease, 5 had recurrent disease, 47 died of cancer, 14 died of causes not related to cancer or treatment and 10 were lost to follow-up. The 5-year actuarial survival rates were, respectively, 45%, 18% and 18% for T3, T4 and Tx. Other significant variables were pN stage (P = 0.0672) and year of admission (0.0318). In conclusion a major glossectomy without laryngectomy whenever possible is a safe procedure for a selected group of patients with advanced tongue and floor of the mouth cancer. The actuarial survival rates presented suggests that, in a very select group of patients, major glossectomy is a surgical procedure to be considered.

Abstract
BACKGROUND Local control, functional outcome, and complications in patients with carcinoma of the base of tongue (BOT) were analyzed to assess the impact of interstitial implant boost with I-125 seeds. METHODS Between December 1986 and May 1995, 16 patients with squamous cell carcinoma of the BOT received treatment at the William Beaumont Hospital and 4 received treatment at the Northern Virginia Cancer Center. The primary tumor classification for this group consisted of T1/T2-11 patients, T3/T4-9 patients. All patients initially received 50.4-66.6 Gray (Gy) (median: 54 Gy) external beam irradiation to the primary site and regional lymph nodes followed by an interstitial implant boost 2 to 3 weeks later. Implant dose ranged from 20 to 32 Gy (median: 27 Gy). The implanted volume included the tumor and glossotonsillar sulcus in all patients and the pharyngeal wall or tonsil in select cases. RESULTS Median follow-up was 47 months (range, 6-88 mos). Two patients have failed within the tumor bed (T2 and T4) for a 5-year actuarial local control rate of 88%. The T2 patient was salvaged surgically, for an overall 5-year actuarial local control rate of 93%. No patients have relapsed within the neck as the only or first site of failure. The 5-year actuarial overall survival rate was 72%. Complications included three cases of exposed bone and one case of cranial nerve XII palsy. All complications were managed conservatively. Excellent to good functional outcome, including speech and swallowing, was preserved in 18 of the 20 patients. CONCLUSIONS Patients with cancer of the BOT can be treated effectively with an interstitial boost utilizing I-125 seeds. Overall, local control is excellent and complications are minimal. Of greatest significance, organ preservation with excellent understandability of speech and diet tolerance was achieved in 90% of the patients.

Abstract
This synthesis of the literature on radiotherapy for head and neck cancer is based on 424 scientific articles, including 3 meta-analyses, 38 randomized studies, 45 prospective studies, and 246 retrospective studies. These studies involve 79174 patients. The literature review shows that radiotherapy, either alone or in combination with surgery, plays an essential role in treating head and neck cancers. When tumors are localized, many tumor patients can be cured by radiotherapy alone and thereby maintain full organ function (1, 2). Current technical advancements in radiotherapy offer the potential for better local tumor control with lower morbidity (3). This, however, will require more sophisticated dose planning resources. To further improve treatment results for advanced tumors, other fractionation schedules, mainly hyperfractionation, should be introduced (5). This mainly increases the demands on staff resources for radiotherapy. The combination of radiotherapy and chemotherapy should be subjected to further controlled studies involving a sufficiently large number of patients (4, 5). Interstitial treatment (in the hands of experienced radiotherapists) yields good results for selected cancers. The method should be more generally accessible in Sweden. Intraoperative radiotherapy should be targeted for further study and development.

Abstract
P-glycoprotein (PGP), which is a product of the multidrug resistance gene (MDR1), is an active transmembrane efflux pump responsible for detoxifying normal cells as well as rendering tumor cells resistant to chemotherapy. It has also been implicated to be expressed by more aggressive cancers. It has not been well described in squamous cell carcinoma of the head and neck. In this investigation, an attempt was made to characterize advanced squamous cell carcinoma of the base of tongue with respect to expression of PGP. Using immunohistochemical techniques two anti-PGP monoclonal antibodies (JSB1 and C494) were used to detect PGP in these lesions, and an attempt was made to correlate levels of PGP staining and various tumor parameters. Usefulness of PGP in predicting survival and time to recurrence was also examined for these advanced lesions. All 33 base of tongue lesions showed staining for PGP with these monoclonal antibodies. This was the first study examining utility of C494 in detecting PGP in squamous cell carcinoma at this site. Increased level of PGP expression was seen in better-differentiated tumors as well as in tumors with diploid DNA. A trend of higher PGP expression and decreased survival emerged. This may represent a true relationship, but inherent heterogeneity of PGP expression within cells cannot be excluded. Both antibodies examined appear to be useful in the investigations of PGP distribution in squamous cell carcinomas of the head and neck sites by immunohistochemical techniques. Prognostic value of the level of PGP expression remains to be seen.

Abstract
We reviewed 90 patients with squamous cell carcinoma of the base of the tongue. Fifty-three patients were treated with external beam radiotherapy alone (3 T1, 11 T2, 21 T3, and 18 T4 tumors) and thirty-seven patients were treated with external beam radiotherapy plus brachytherapy boost (4 T1, 15 T2, 11 T3, and 7 T4 tumors). For patients with T1, T2 and T3 primaries, the actuarial 3-year local relapse-free survival was 42% following external beam radiotherapy alone and 67% following external beam radiotherapy plus brachytherapy (p < 0.05). The actuarial 3-year cause specific survival for these T-stages was 37% for patients treated with external beam radiotherapy alone and 53% for patients treated with external beam radiotherapy plus brachytherapy (p = 0.1). In the Cox multivariate analyses restricted patients with T1, T2 and T3 staged tumors, treatment modality was the only predictor for local control but no influence on specific survival was found. The trend towards significant differences in specific survival found in the univariate comparison of both treatment modalities was probably due to the significantly higher number of N-positive patients treated with external beam radiotherapy alone. When all stages were included in the Cox analysis, low hemoglobin level, invasion of deep muscle, number of palpable nodes, and history of weight loss significantly influenced the outcome. Soft tissue necrosis occurred more frequently in patients treated with external beam radiotherapy plus brachytherapy (33% vs. 10%, p = 0.52).

Abstract
The prognostic significance of lymph node metastases was evaluated in an unselected material of 427 oropharyngeal cancer patients treated primarily with radiotherapy. At first referral, palpable lymph node metastases were present in 60% of the patients. After irradiation, 60% of all palpable nodes had disappeared. As many as 50% of the nodes initially palpable in N3 patients vanished after irradiation. Recurrences were significantly increased in patients primarily with lymph node metastases (N1-3) compared with N0 patients; recurrences in the primary tumour site were (56% vs. 43%) in neck lymph nodes (40% vs. 9%) and in distant metastases (14% vs. 5%). Surgery was performed in 98 of 256 patients (38%) with recurrent or metastatic disease. The 5-year disease-free survival rate after radiotherapy for N0 patients was an improvement (44%) on that of N1-3 patients (23%). The N-stage is an important prognostic factor for oropharyngeal cancer patients.

Abstract
Carcinoma of the oropharynx poses particular challenges and problems to head and neck clinicians. These include relative anatomic inaccessibility, field cancerization and the need to minimize speech and swallowing dysfunction. The aim of this review is to bring together an appreciation of the issues involved in the management of this disease and the more recent results of its treatment.

Abstract
We have performed univariate and multivariate analysis to identify the clinical and treatment-related prognostic factors in a series of 254 patients with newly diagnosed, histologically proven, oropharyngeal squamous cell carcinoma treated with radical radiation therapy. The probabilities of local control, regional control, disease-free survival (DFS) and adjusted survival (AS) were calculated using the Kaplan-Meier method and differences between curves were evaluated by the Mantel-Cox test. The obtained significant variables in the univariate analysis were analysed using the Cox proportional hazards model. In the Cox multivariate analysis, four variables significantly influenced local control probability in the following order: tumour diameter, N stage, alcohol intake and weight loss. N stage significantly influenced the probability of regional control. Five variables influenced both DFS and AS: N stage, tumour diameter, weight loss, alcohol intake and tumour origin within the posterior oropharyngeal wall.

Abstract
Sixteen squamous cell carcinomas of the tonsillar region and 13 carcinomas of the base of the tongue were studied in a search for significant differences between the tumours of these two oropharyngeal subsites, which are known to carry a significantly different prognosis. The characteristics of the tumour cells and the tumour-host relationship were scored on H & E-stained slides, as well as on slides stained with a panel of antibodies. The results obtained were cross-tabulated and analysed with respect to the subsite. Ten variables were tested: cytonuclear pleomorphism, mitotic activity, the presence of atypical mitoses, keratinization, tumour grade, presence of eosinophils, severity of inflammatory response, and the expression of keratin-10, blood group antigens and collagen IV. When split up by site, only cytonuclear pleomorphism revealed a significant difference, tonsillar carcinomas more often exhibiting marked pleomorphism (p = 0.04). Despite having some prognostic relevance for squamous cell carcinomas of the head and neck, the variables tested could not provide an explanation for the difference in biological behaviour of the tumours studied.

Abstract
119 patients with squamous cell carcinoma of the tonsillar region (68) and the base of the tongue (51), who received external radiotherapy with curative intent between 1966 and 1984, are analysed with respect to overall treatment results, local tumour control and prognostic factors. Radiation doses were equivalent to 60-70 Gy in 6-7 weeks, with a mean fraction dose of 2.4 Gy on the cobalt 60 equipment and 2 Gy on the linear accelerator. Significant differences were found between both oropharyngeal subsites. Three-year overall survival was 57% in tonsillar carcinoma and 38% in base of the tongue (P = 0.006); disease-specific survival was 70% and 47%, respectively (P = 0.005); and local control rates were 82% and 61% (P = 0.02). Late damage to normal tissues, like persistent dysphagia and osteomyelitis, were seen in 11% of patients. Patients with large tumours in the tongue based developed significantly more complications (P = 0.04). T-stage and tumour subsite predicted local control independently before start of the treatment (P = 0.02 in both cases). A significant nonlinear correlation between Normalised Total Dose (using an alpha/beta ratio of 15 Gy) and local control rate was found (P = 0.006), the middle range having the worst prognosis. The size of radiation field and overall treatment time did not correlate with local control in either site. Response at the end of radiotherapy and 6 weeks later have additional prognostic value for local control, irrespective of the initial stage or subsite (P = 0.004 and < 0.001, respectively).

Abstract
Occult thyroid cancer is an occasional incidental finding during surgery for other indications and is usually considered of minor clinical significance; however, the appropriate approach for incidentally found metastatic thyroid cancer is less clear especially when it occurs in the context of another malignancy that has more aggressive potential. Among 2,855 patients treated for squamous cancer of the tongue at The University of Texas M. D. Anderson Cancer Center, eight patients had coexisting differentiated thyroid cancer metastatic to cervical lymph nodes which was found incidentally during regional lymph node dissection. The eight patients included three women and five men with a median age of 47 years (range, 32-62 years); tumors were of the papillary variety in four patients and follicular in the other four. In one patient, no gross or microscopic primary tumor could be identified after thyroidectomy; in another patient, no gross tumor was evident, but whole organ section revealed an area of fibrosis consistent with a primary lesion. Two patients had primary lesions less than 1 cm in maximal diameter. In four patients who had no surgery, physical exam and radiologic evaluation failed to show any intrathyroidal lesions. Clinically relevant thyroid cancer did not develop in any of those patients during the duration of documented follow-up (1-15 years). Three patients died of progressive tongue cancer, one patient of unrelated pulmonary disease, and four patients remain alive without evidence of disease for 1 to 15 years of available follow-up.(ABSTRACT TRUNCATED AT 250 WORDS)
