Abstract
The purpose was to determine the maximum tolerated dose (MTD) of weekly paclitaxel with concurrent, daily irradiation in patients with unresectable head and neck squamous cell carcinoma previously submitted to induction chemotherapy. Patients with stage IV, and unresectable tumor and/or node/s were enrolled. Nine male patients were submitted to a course of paclitaxel 175 mg/m2 day 1 and cisplatin 75 mg/m2 day 2 given every 3 weeks for three courses. Curative radiotherapy (RT) started 3 weeks after the last cycle of chemotherapy with the goal of delivering a total dose of 66-70 Gy. During RT weekly paclitaxel was administered for 6 courses if feasible; paclitaxel was given according to a dose escalation schema in cohorts of three patients. Dose level A, 30 mg/m2; dose level B, 40 mg/m2; dose level C, 50 mg/m2. During weekly paclitaxel the major toxicity was mucositis that required a treatment break in two of three patients in dose level C; mucositis grade 4 required interruption of paclitaxel administration in all these patients. RT can be given in a continuous fashion with weekly paclitaxel after induction chemotherapy. The MTD of weekly paclitaxel was 40 mg/m2.

Abstract
A group of Swedish oncologists and hospital physicists have estimated the number of patients in Sweden suitable for proton beam therapy. The estimations have been based on current statistics of tumour incidence, number of patients potentially eligible for radiation treatment, scientific support from clinical trials and model dose planning studies and knowledge of the dose-response relations of different tumours and normal tissues. In head and neck cancer, including thyroid cancer, it is assessed that at least 300 patients annually will gain sufficiently from proton beam therapy, both to improve tumour control and to decrease toxicity to compensate for the increased treatment costs using protons.

Radiother Oncol 2009; 90:189-95. [PMID: 19167120 DOI: 10.1016/j.radonc.2008.12.017] [Citation(s) in RCA: 136] [Impact Index Per Article: 9.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/24/2008] [Revised: 12/30/2008] [Accepted: 12/31/2008] [Indexed: 10/21/2022]
Abstract
INTRODUCTION Recently, we found that swallowing dysfunction after curative (chemo) radiation (CH) RT has a strong negative impact on health-related quality of life (HRQoL), even more than xerostomia. The purpose of this study was to design a predictive model for swallowing dysfunction after curative radiotherapy or chemoradiation. MATERIALS AND METHODS A prospective study was performed including 529 patients with head and neck squamous cell carcinoma (HNSCC) treated with curative (CH) RT. In all patients, acute and late radiation-induced morbidity (RTOG Acute and Late Morbidity Scoring System) was scored prospectively. To design the model univariate and multivariate logistic regression analyses were carried out with grade 2 or higher RTOG swallowing dysfunction at 6 months as the primary (SWALL(6months)) endpoint. The model was validated by comparing the predicted and observed complication rates and by testing if the model also predicted acute dysphagia and late dysphagia at later time points (12, 18 and 24 months). RESULTS After univariate and multivariate logistic regression analyses, the following factors turned out to be independent prognostic factors for SWALL(6months): T3-T4, bilateral neck irradiation, weight loss prior to radiation, oropharyngeal and nasopharyngeal tumours, accelerated radiotherapy and concomitant chemoradiation. By summation of the regression coefficients derived from the multivariate model, the Total Dysphagia Risk Score (TDRS) could be calculated. In the logistic regression model, the TDRS was significantly associated with SWALL(6months) ((p<0.001). Subsequently, we defined three risk groups based on the TDRS. The rate of SWALL(6months) was 5%, 24% and 46% in case of low-, intermediate- and high-risk patients, respectively. These observed percentages were within the 95% confidence intervals of the predicted values. The TDRS risk group classification was also significantly associated with acute dysphagia (P<0.001 at all time points) and with late swallowing dysfunction at 12, 18 and 24 months (p<0.001 at all time points). CONCLUSION The TDRS is a simple and validated measure to predict swallowing dysfunction after curative (CH) RT for HNC. This classification system enables identification of patients who may benefit from strategies aiming at prevention of swallowing dysfunction after curative (CH) RT such as preventive swallowing exercises during treatment and/or emerging IMRT techniques aiming at sparing anatomical structures that are involved in swallowing.

Abstract
PURPOSE The management of patients with cervical lymph-node metastases from unknown primary site (UPS) remains a matter of discussion. This study aimed to analyze the results and prognostic factors in a series of patients treated with radiotherapy. METHODS AND MATERIALS Data from 113 patients who presented with cervical lymph nodes metastases from UPS treated from 1980 to 2004 were reviewed. Eighty-seven patients (77.0%) were squamous cell carcinoma (SCC). Ninety-one patients were treated with curative and 22 with palliative intent. Fifty-nine of 113 patients (52.2%) received surgery followed by radiotherapy and 54 of 113 (47.8%) received radiotherapy alone. Radiotherapy was delivered to the neck and pharyngeal mucosa in 67 patients and to the ipsilateral or bilateral neck in 45 patients. Twenty-one patients (18.5%) also received chemotherapy. RESULTS The 5-year overall survival rates were 40.7% for the entire group and 46.6% for the SCC subgroup. The occurrence of the occult primary was observed in 23 of 113 patients (20.3%), 19 (82.6%) within the head and neck region. At multivariate analysis, treatment with curative intent and extensive irradiation of bilateral neck and pharyngeal mucosa were favorable prognostic factors for the whole series, and treatment with curative intent, extensive irradiation of bilateral neck and pharyngeal mucosa, and absence of extracapsular spread were favorable prognostic factors for the SCC subgroup. CONCLUSIONS Patients with cervical lymph node metastases from UPS have a similar prognosis to those affected by other head and neck malignancies. Curative treatment strategies including neck dissection and extensive irradiation by three-dimensional conformal radiation therapy resulted in significantly better outcomes.

Abstract
PURPOSE To determine efficacy and toxicities of postoperative concurrent chemoradiation using docetaxel in high-risk head and neck cancer. METHODS AND MATERIALS High-risk patients were enrolled 2-8 weeks after surgery. Treatment included 60 Gy for 6 weeks with weekly docetaxel 25 mg/m(2) and erythropoietin alpha 40,000 U for hemoglobin < or =12 g/dL. Primary endpoints included locoregional control (LC), disease-free survival (DFS), and patterns of failure (POF). Secondary endpoints were toxicity and quality of life. RESULTS Eighteen patients were enrolled (14 male, 4 female), aged 24-70 years (median, 55 years). Primary site included oropharynx = 7, oral cavity = 8, hypopharynx = 1, and larynx = 2. Pathologic American Joint Committee on Cancer Stage was III = 3 patients, IV = 15 patients. High-risk eligibility included > or =2 positive lymph nodes = 13, extracapsular extension = 10, positive margins = 8 (11 patients with two or more risk factors). Docetaxel was reduced to 20 mg/m(2)/week after 5 patients had prolonged Grade 3 or higher mucositis. Overall, number of doses delivered was 2 of 6 = 1, 3 of 6 = 2, 4 of 6 = 2, 5 of 6 = 4, 6 of 6 = 9 patients. With median follow-up of 30 months (range, 5-66), 10 (56%) patients are alive and have no evidence of disease (NED); POF: three local recurrences (two with distant) and 1 distant only. One-year survival was 76%, median PFS and DFS had not been reached. Three-year LC was 82%. No Grade 3 or higher late toxicities were observed, although a few cases of prolonged mucositis and taste loss (>3 months) were seen, particularly at 25 mg/m(2)/week. CONCLUSION Postoperative radiation therapy with weekly docetaxel 20 or 25 mg/m(2)/week for high-risk postoperative head and neck cancer caused intolerable mucosal toxicity, prompting early study termination. Further studies should consider 15 mg/m(2). Actuarial 3-year LC is 82%, similar to cisplatin-based chemoradiation regimens. Distant metastasis remains an important issue requiring additional systemic interventions.

Abstract
To investigate the response of tumour growth to cisplatin treatment, in relation to p53 mutation and cyclin D1 dysregulation on DNA and protein level, biopsies from seven xenografted human squamous cell carcinomas from the head and neck were analysed with immunohistochemistry for p53 expression and cyclin D1 expression. Polymerase chain reaction-singlestranded conformation polymorphism was used to determine p53 mutations. Fluorescence in situ hybridization was performed to analyse cyclin D1 amplification. The mice were injected i.p. with NaCl (controls) or cisplatin. After injection the tumour volume were measured. The inhibition of tumour growth by cisplatin was defined as the area under the growth curves, and compared with the growth curves of the tumours in the control group. Xenografts with p53 mutation showed significantly higher resistance to cisplatin (p < 0.001) and also tumours with cyclin D1 amplification showed significantly higher resistance (p < 0.001).

Abstract
PURPOSE To investigate whether intensity-modulated radiation therapy (IMRT) allows more mucosal sparing than standard three-field technique (3FT) radiotherapy for early oropharyngeal cancer. METHODS AND MATERIALS Whole-field IMRT plans were generated for 5 patients with early-stage oropharyngeal cancer according to Radiation Therapy Oncology Group 0022 (66 Gy/30 fractions/6 weeks) guidelines with and without a dose objective on the portion of mucosa not overlapping any PTV. 3FT plans were also generated for the same 5 patients with two fractionation schedules: conventional fractionation (CF) to 70 Gy/35 fractions/7 weeks and concomitant boost (CB) to 72 Gy/40 fractions/6 weeks. Cumulative dose volume histograms (DVHs) of the overall mucosal volume (as per in-house definition) from all trials were compared after transformation into the linear quadratic equivalent dose at 2 Gy per fraction with a time factor correction. RESULTS Compared with IMRT without dose objective on the mucosa, a 30-Gy maximum dose objective on the mucosa allows approximately 20% and approximately 12% mean absolute reduction in the percentage of mucosa volume exposed to a dose equivalent to 30 Gy (p < 0.01) and 70 Gy (p < 0.01) at 2 Gy in 3 and 7 weeks, respectively, without detrimental effect on the coverage of other regions of interest. Without mucosal dose objective, IMRT is associated with a larger amount of mucosa exposed to clinically relevant doses compared with both concomitant boost and conventional fractionation; however, if a dose objective is placed, the reverse is true, with up to approximately 30% reduction in the volume of the mucosa in the high-dose region compared with both concomitant boost and conventional fractionation (p < 0.01). CONCLUSIONS Intensity-modulated radiation therapy can be potentially provide more mucosal sparing than traditional approaches.

Abstract
PURPOSE Squamous cell carcinoma of the head and neck (HNSCC) remains a clinical challenge because of the high rate of locoregional disease recurrence. Standard treatment includes surgery, radiation, chemoradiation or a combination of these approaches. New therapies are needed to achieve improved survival, quality of life and organ function in these patients. A novel molecular targeted therapy incorporated into our current treatment strategies may have a significant role in the treatment of HNSCC. The aim of this study was to evaluate the sensitivity of HNSCC cell lines to vinorelbine combined with gefitinib in vitro. METHODS Six recently established cell lines were used: UT-SCC-9, -11, -19A, -29 and -34 (laryngeal SCC) and UT-SCC-33 (oral cavity SCC). Chemosensitivity was tested using the 96-well plate clonogenic assay. The vinorelbine concentrations used varied between 0.4 and 1.0 nM and the gefitinib concentrations varied between 0.05 and 1.6 muM. Survival data were fitted to the LQ model, and the area under the curve (AUC) value was obtained with numerical integration. The type of interaction was determined by comparing the AUC ratio of the two drugs to the survival fraction (SF) of gefitinib alone. RESULTS In the current study the combination of vinorelbine and gefitinib had a clear supra-additive or additive cytotoxic effect on the HNSCC cell lines. CONCLUSIONS This finding is encouraging as a proof of the possible benefit of combing an EGFR targeting compound with a cell cycle specific drug and warrants further studies of available combinations in vitro.

Abstract
PURPOSE With the aim to increase the dose intensity of radiation therapy (RT), and subsequently the locoregional control rate, a very accelerated RT regimen was compared with conventional RT in a series of patients with head and neck squamous cell carcinoma (HNSCC). PATIENTS AND METHODS Between 1994 and 1998, 268 patients with T3 or T4, N0 to N3 HNSCC (staged by 1997 International Union Against Cancer criteria) that was not eligible for surgery were randomly assigned to receive either conventional RT, delivering 70 Gy in 7 weeks to the primary tumor and 35 fractions of 2 Gy over 49 days, or to receive very accelerated RT, delivering 62 to 64 Gy in 31 to 32 fractions of 2 Gy over 22 to 23 days (2 Gy/fraction bid). RESULTS The most common tumor site was the oropharynx and most of the patients (70%) had T4 and N1 to N3 tumors in 72% of patients. The main patient and tumor characteristics were well-balanced between the two arms. The median total doses were 63 Gy (accelerated) and 70 Gy (conventional), with a median overall time of 22 days and 48 days, respectively. Acute mucositis was markedly increased in the accelerated-RT arm (P < .001). The locoregional control rate was improved by 24% at 6 years with accelerated RT. In contrast, disease-free survival and overall survival were not significantly different between the two arms. There was no difference in late effects between the two arms. CONCLUSION The very accelerated RT regimen was feasible and provided a major benefit in locoregional control but had a modest effect on survival.

Abstract
Radiotherapy and chemotherapy are given in multiple doses, which are spaced out to allow the recovery of normal tissues between treatments. However, surviving cancer cells also proliferate during the intervals between treatments and this process of repopulation is an important cause of treatment failure. Strategies developed to overcome repopulation have improved clinical outcomes, and now new strategies to inhibit repopulation are emerging in parallel with advances in the understanding of underlying biological mechanisms.

Abstract
INTRODUCTION Malignancies of the nasal and paranasal sinuses are uncommon tumors, accounting for only 3% of all aerodigestive tract neoplasms. Despite advances in surgical techniques and continued evolution of adjuvant therapies, the 5-year mortality remains unusually high at greater than 50%. In 1996, we begin utilizing a novel strategy in the treatment of advanced sinonasal carcinomas. This consisted of neoadjuvant selective intra-arterial cisplatin with concurrent radiation therapy (acronym RADPLAT) followed by a conservative craniofacial resection. We now report our results for 11 patients treated with this regimen. METHODS Between July 1996 and April 2003, 11 patients with advanced sinonasal malignancies underwent treatment utilizing the RADPLAT protocol followed by a planned surgical resection via a craniofacial approach. Patient charts, operative notes, follow-up clinic notes, and pre- and post-operative imaging studies were reviewed in detail for each subject. RESULTS Histopathological analysis of the tumors revealed seven squamous cell carcinomas (64%), two adenocarcinomas (18%), one adenoid cystic carcinoma (9%), and one sinonasal undifferentiated carcinoma (9%). T4N0M0 disease was present in nine patients (81%), and two patients had T3N0M0 disease (19%). Survival was calculated using the Kaplan-Meier method with an overall survival of 81% at 5 years and a progression-free survival at 5 years of 67%. Mean follow-up is 57.2 months ranging from 12 to 95 months. CONCLUSIONS The treatment of advanced sinonasal malignancies with pre-operative intra-arterial cisplatin and concurrent radiation results in a significant improvement in survival. This can be done safely with high response rates and excellent loco-regional control in T3 and T4 disease. Although are results are encouraging, there is a need for a cooperative, multi-institutional, prospective study.

Abstract
INTRODUCTION We undertook a prospective study to determine the feasibility, toxicity, response and survival rate of simultaneous chemotherapy (CT) and radiotherapy (RT) for locally-advanced head and neck cancer. MATERIAL AND METHODS Fifty eight patients were treated with carboplatin (i.e. 100 mg/m(2)) weekly, tegafur-uracil (UFT) (oral 400 mg/m(2)) daily and simultaneous treatment with a cobalt-60 source of radiation (total dose 65-70 Gy). RESULTS Forty six patients (79%) received the total dose of RT while CT was delayed or reduced in 31 patients (53%). Grade 3-4 toxicity observed was mucositis in 27 (47%), leukopenia in 10 (17%), anaemia in 5 (9%), and diarrhoea in 4 (7%) patients. The objective response rate was 74%; 24 complete response (41%) and 19 partial response (33%). Overall, there are 11 patients (19%) disease-free, 7 (12%) alive with disease, 35 have died of progressive disease (60%) and 3 (5%) from other causes. There were 2 toxic deaths (3%). Median time to progression was 10 months and median survival was 18.4 months. CONCLUSIONS The use of carboplatin and UFT concomitant with radiotherapy has, in our study, a slightly lower activity than other chemo-radiotherapy protocols, especially with respect to complete responses, but with no significant differences in overall survival or disease-free survival rates.

Abstract
Concurrent chemotherapy and radiation has improved the outcome for patients presenting with locally advanced squamous cell carcinomas of the head and neck (SCCHN). These improvements have come at a cost of increased treatment-related toxicities. We previously reported the results of a phase II trial examining the role of concurrent carboplatin, paclitaxel, and daily radiotherapy (RT) in SCCHN. In an attempt to decrease these side effects, we conducted a prospective phase II trial evaluating the role of amifostine (Ethyol, MedImmune Oncology, Inc, Gaithersburg, MD) in patients treated with this concurrent chemoRT scheme. From April 2002 to September 2004, 19 patients with stage III-IV SCCHN were enrolled on a prospective phase II trial. Treatment consisted of daily RT delivered to 70.2 Gy (1.8 Gy/fx) with amifostine 500 mg IV (<1 hour before RT), and concurrent weekly carboplatin (100 mg/m2) and paclitaxel (40 mg/m2). Median age was 58.5 years (range, 48 to 70 years); male to female ratio was, 83%:17%; Caucasian versus other was, 61%/39%. Tumor characteristics based on histology were: primary cancers of the oropharynx (55.6%); supraglottic larynx (16.7%); hypopharynx (16.7%); oral cavity (5.6%); and unknown primaries (5.6%). All patients presented with locally advanced, unresectable disease T4 (50%), T3 (27.8%), and advanced nodal disease (N2b-N3) (78%). Toxicities were measured weekly during treatment and at each follow-up visit. Disease response to therapy was determined 2 months after completion of therapy. Seventeen patients are evaluable for response and survival at 2 months following completion of RT. Eighty-four percent completed the prescribed radiation treatment, and 84% of patients received more than six cycles of chemotherapy. The median number of missed chemotherapy cycles was 1.5 (range, 0 to 5 cycles). Fifty-six percent of patients received more than 90% of prescribed amifostine doses, with chemoRT-related toxicity being the most common reason for withholding the dose (77%). Median doses of missed amifostine were three (range, 0 to 30 doses). Grade 3 toxicities associated with therapy were: mucositis and dysphagia (40% of patients each), dehydration (27%), xerostomia (20%), and dermatitis (20%); 53% of patients experienced grade 3 leukopenia, while grade 3/4 neutropenia developed in 20%/13%. No grade 4/5 nonhematologic toxicities were encountered. Forty percent of patients completed RT without unscheduled treatment breaks secondary to treatment-related toxicity. Median treatment-break time was 5 days (range, 0 to 20 days). Clinical complete response at both the primary site of disease and neck was achieved in 75% of patients 2 months following completion of RT. Weekly carboplatin and paclitaxel administered concurrently with definitive RT and daily amifostine is well tolerated, with over 85% of patients completing therapy with acceptable toxicity. The addition of amifostine appears to decrease treatment-related toxicity without impacting efficacy.

Abstract
AIMS Predictors of outcome after radiotherapy alone for nasopharyngeal carcinoma (NPC) are now available from several retrospective studies. On the basis of these, it is theoretically possible to separate patients at risk of local failure from patients at risk of distant metastases (DM). According to classical principles of chemoradiotherapy timing, patients at risk of local failure would benefit mostly from concomitant chemoradiotherapy, whereas patients at risk distantly would benefit from sequential combinations. MATERIALS AND METHODS We reviewed the literature on combined chemoradiotherapy treatment for nasopharyngeal carcinoma to assess whether timing of combined treatment matches pattern of failure. RESULTS Available data show a significant overlap of activity, sequential treatments reducing local failure and concomitant treatments reducing DM. Therefore, in the individual patient, the strict adoption of traditional risk profiles in therapeutic decision-making may not fully exploit all the potential therapeutic effects derived from the maximal association of both sequential and concomitant therapies. CONCLUSION Whether such combination is clinically worthwhile in every patient with locoregionally advanced nasopharyngeal carcinoma needs prospective validation, because of the high toxicity of this modality.

Abstract
The objective of this study is to compare the results of an individual patient-based and a literature-based meta-analysis in chemotherapy in head and neck cancer and to identify the sources of difference. For all head and neck cancer randomized controlled clinical trials comparing chemotherapy and loco-regional treatment with loco-regional treatment alone, both the literature data and the individual patient data are retrieved and meta-analyses performed and compared. Only survival data are used as outcome, although both time to death and mortality at specific time points are considered in different analyses. There are substantial differences between the individual patient-based and the literature-based meta-analyses. The most important reason for the differing results is that the individual patient-based meta-analysis is based on a time to event analysis, whereas the literature-based meta-analysis is based on mortality at a specific time point. Mortality can change substantially with follow-up time. The absolute survival differences in the case study, for instance, increase from 2.6% at 2 years to 5.6% at 5 years.

Abstract
PURPOSE To demonstrate the efficacy of radiochemotherapy (RCT) as the first choice of treatment for advanced unresectable head-and-neck cancer. To prove an expected benefit of simultaneously given chemotherapy, a two-arm randomized study with hyperfractionated accelerated radiochemotherapy (HF-ACC-RCT) vs. hyperfractionated accelerated radiotherapy (HF-ACC-RT) was initiated. The primary endpoint was 1-year survival with local control (SLC). METHODS AND MATERIALS Patients with Stage III and IV (UICC) unresectable oro- and hypopharyngeal carcinomas were randomized for HF-ACC-RCT with 2 cycles of 5-FU (600 mg/m(2)/day)/carboplatinum (70 mg/m(2)) on days 1--5 and 29--33 (arm A) or HF-ACC-RT alone (arm B). In both arms, there was a second randomization for testing the effect of prophylactically given G-CSF (263 microg, days 15--19) on mucosal toxicity. Total RT dose in both arms was 69.9 Gy in 38 days, with a concomitant boost regimen (weeks 1--3: 1.8 Gy/day, weeks 4 and 5: b.i.d. RT with 1.8 Gy/1.5 Gy). Between July 1995 and May 1999, 263 patients were randomized (median age 56 years; 96% Stage IV tumors, 4% Stage III tumors). RESULTS This analysis is based on 240 patients: 113 patients with RCT and 127 patients with RT, qualified for protocol and starting treatment. There were 178 oropharyngeal and 62 hypopharyngeal carcinomas. Treatment was tolerable in both arms, with a higher mucosal toxicity after RCT. Restaging showed comparable nonsignificant different CR + PR rates of 92.4% after RCT and 87.9% after RT (p = 0.29). After a median observed time of 22.3 months, l- and 2-year local-regional control (LRC) rates were 69% and 51% after RCT and 58% and 45% after RT (p = 0.14). There was a significantly better 1-year SLC after RCT (58%) compared with RT (44%, p = 0.05). Patients with oropharyngeal carcinomas showed significantly better SLC after RCT (60%) vs. RT (40%, p = 0.01); the smaller group of hypopharyngeal carcinomas had no statistical benefit of RCT (p = 0.84). For both tumor locations, prophylactically given G-CSF was a poor prognostic factor (Cox regression), and resulted in reduced LRC (log-rank test: +/- G-CSF, p = 0.0072). CONCLUSION With accelerated radiotherapy, the efficiency of simultaneously given chemotherapy may be not as high as expected when compared to standard fractionated RT. Oropharyngeal carcinomas showed better LRC after HF-ACC-RCT vs. HF-ACC-RT; hypopharyngeal carcinomas did not. Prophylactic G-CSF resulted in an unexpected reduced local control and should be given in radiotherapy regimen only with strong hematologic indication.

Abstract
PURPOSE The present study presents the experience at the University of Florida with treatment of unselected patients with carcinomas of the soft palate with radiation therapy (RT) alone or followed by planned neck dissection. METHODS AND MATERIALS One hundred seven patients treated with curative intent with RT alone or followed by neck dissection from 1965 to 1996 were included in the study. All patients had follow-up for at least 2 years. No patients were lost to follow-up. RESULTS Local control rates at 5 years were 86% for T1, 91% for T2, 67% for T3, and 36% for T4 carcinomas. T-stage and overall treatment time significantly affected local control in multivariate analysis. Nodal control rates at 5 years were 86% for NO, 76% for N1, 61% for N2, and 67% for N3 carcinomas. Overall treatment time and planned neck dissection significantly affected nodal control in multivariate analysis. Ultimate local-regional control rates at 5 years were 90% for Stage I, 92% for Stage II, 84% for Stage III, and 60% for Stage IV disease. Overall treatment time and planned neck dissection significantly affected ultimate local-regional control in multivariate analysis. The overall survival rate at 5 years was 42% for all patients. Overall stage, overall treatment time, and planned neck dissection significantly affected overall survival in multivariate analysis. The cause-specific survival rate at 5 years was 70% for all patients. Overall treatment time and planned neck dissection significantly affected cause-specific survival in multivariate analysis. Three patients sustained severe postoperative complications and 3 patients sustained severe late complications. Sixteen patients had synchronous and 14 patients had metachronous carcinomas of the head and neck mucosal sites. CONCLUSION For limited carcinomas of the soft palate, RT (alone or followed by planned neck dissection) results in relatively high local-regional control and survival rates. For advanced carcinomas of the soft palate, local-regional control and survival rates are relatively low and local-regional recurrence rates are substantial. Advanced carcinomas of the soft palate may be better treated with RT and concomitant chemotherapy.

Abstract
PURPOSE To report long-term results using radiotherapy with or without a planned neck dissection for T1-T2 carcinoma of the pyriform sinus. METHODS An analysis of 101 patients treated at the University of Florida with RT with or without a planned neck dissection for organ preservation. RESULTS The 5-year local control rates after RT were 90% for T1 cancers and 80% for T2 lesions. The only parameter that significantly influenced local control in univariate analyses was apex involvement for T1 tumors. Multivariate analysis revealed no parameter that significantly affected local control. Cause-specific survival rates at 5 years were as follows: stage I-II, 96%; stage III, 62%; stage IVA, 49%; and stage IVB, 33%. The absolute survival rates were as follows: stage I, 57%; stage II, 61%; stage III, 41%; stage IVA, 29%; and stage IVB, 25%. Moderate to severe long-term complications developed in 12% of patients. CONCLUSIONS RT alone or combined with a planned neck dissection resulted in local control with larynx preservation in a high proportion of patients. The chance of cure is comparable to that observed after conservation surgery, and the risk of major complications is lower. The addition of adjuvant chemotherapy is unlikely to improve the probability of organ preservation, but might improve locoregional control for patients with advanced nodal disease.

Abstract
Treatment of laryngeal and hypopharyngeal cancers often necessitates total laryngectomy. This article reviews approaches of curing patients with these diseases while preserving their larynx. Strategies include radiation alone, neoadjuvant chemotherapy with radiation for responders, or concurrent chemotherapy and radiation. Both retrospective experiences and randomized trials evaluating differing therapies in an effort to achieve voice preservation are reported and analyzed.

Abstract
PURPOSE To determine the feasibility of an organ preservation regimen consisting of infusional paclitaxel administered concurrently with radiotherapy to patients with locally advanced head and neck squamous cell carcinoma (HNSCC). PATIENTS AND METHODS Thirty-three previously untreated patients with stage III or IV tumors were enrolled onto the study. Paclitaxel was administered as a 120-hour continuous infusion every 3 weeks during the course of radiation therapy. Sixteen patients received a paclitaxel dose of 105 mg/m(2), and 17 patients received 120 mg/m(2). Radiation was delivered in a standard format at 1.8 Gy/d to a total dose of 70.2 to 72 Gy. RESULTS Three months after therapy, a 76% complete response (CR) at the primary site and a 70% overall CR was achieved. At 36 months, locoregional control was 55.7%, overall survival was 57.8%, and disease-free survival was 51.1%. The median survival duration for all 33 patients was greater than 50 months at the time of this report. Local toxicities including mucositis, dysphagia, and skin reactions were severe but tolerable. All patients retained functional speech, and all but four patients were swallowing food 3 months after treatment. Steady-state plasma concentrations for paclitaxel were not achieved during a 120-hour infusion, suggesting a nonlinear process. Tumor volume quantified by pretreatment computerized tomography imaging was associated with likelihood of response and survival. CONCLUSION Paclitaxel administered as a 120-hour continuous infusion in combination with radiotherapy is a feasible and promising treatment for patients with advanced HNSCC.

Abstract
Although it is possible to cure many patients with locally advanced cervical cancer using radiation therapy alone, loco-regional relapse continues to be a component of most recurrences. To improve control rates, clinicians have investigated ways of combining chemotherapy and radiation for more than 30 years. Despite encouraging results from phase II trials of neoadjuvant chemotherapy, randomized trials failed to improve on the results with radiation therapy alone. For a number of reasons, early trials of concurrent chemoradiation were inconclusive. However, recent reports of five large prospective randomized trials demonstrated dramatic improvements in survival and local control rates when cisplatin-containing chemotherapy was given during radiation therapy. These results also suggest a number of avenues for future research.

Abstract
BACKGROUND Concomitant chemoradiotherapy is an effective treatment modality for advanced head and neck cancer, but improved regimens are needed. We sought to define the toxicities, recommended phase II dose, and outcome of a combination chemotherapy regimen with concomitant hyperfractionated radiotherapy in patients with poor prognosis cancers of the head and neck, including those having received prior curative intent radiotherapy. PATIENTS AND METHODS From 1995 until 1997, 54 patients were treated, 25 of whom had received a prior full course of radiotherapy to the head and neck. Patients were treated with 5-fluorouracil (5-FU) 600 mg/m2/day continuous infusion x 5 days (days 1-5), hydroxyurea, 500 mg p.o. bid x 11 doses (days 1-6) and paclitaxel (60-150 mg/m2) by one-hour infusion on day 2 using a dose escalation strategy. Radiotherapy was given concomitantly on days 2-6, 150 cGy bid. Each of 4-5 cycles was delivered every other week. RESULTS The MTD of paclitaxel was 100 mg/m2. The regimen was feasible; radiotherapy was delivered at a median of 7300 cGy and 83% of patients received > or = 80% planned dose intensity. Hematological toxicity, with granulocyte colony stimulating factor, was very mild. Dose limiting toxicities were mucositis and dermatitis. Despite poor prognosis, two-year survival was 45%. CONCLUSIONS The recommended phase II dose of this regimen is 5-FU 600 mg/m2/day x 120 hours (days 1-5), hydroxyurea 500 mg p.o. b.i.d. x 11 doses (days 1-6), paclitaxel 100 mg/m2 over one hour on day 2, and radiotherapy 150 cGy b.i.d. days 2-6. Concomitant chemotherapy and re-irradiation was feasible on this protocol and resulted in long-term survival in patients without other curative intent options.

Abstract
Chemotherapy has become integrated into the treatment of head and neck cancer in not only the palliative but now also the primary setting. Organ preservation is possible using induction chemotherapy, and improved survival results have been confirmed for concomitant chemoradiotherapy. The taxanes, paclitaxel and docetaxel, appear to be as active as any other drugs in head and neck cancer. When used in combination in the induction, recurrent, or metastatic settings, response rates rival those of the standard cisplatin/5-fluorouracil regimen. At least one ongoing study will help to establish superiority of cisplatin/paclitaxel versus cisplatin/5-fluorouracil in the recurrent or metastatic setting, and another between cisplatin/5-fluorouracil and doctaxel/cisplatin/5-fluorouracil in the induction setting. Both paclitaxel and docetaxel are being extensively studied as radiosensitizers. They are relatively well tolerated and have good efficacy but have not yet been adequately studied in comparison with other regimens. In conclusion, the taxanes have significantly expanded our effective treatment options in both the primary and recurrent or metastatic settings.

Abstract
BACKGROUND Despite more than 70 randomised trials, the effect of chemotherapy on non-metastatic head and neck squamous-cell carcinoma remains uncertain. We did three meta-analyses of the impact of survival on chemotherapy added to locoregional treatment. METHODS We updated data on all patients in randomised trials between 1965 and 1993. We included patients with carcinoma of the oropharynx, oral cavity, larynx, or hypopharynx. FINDINGS The main meta-analysis of 63 trials (10,741 patients) of locoregional treatment with or without chemotherapy yielded a pooled hazard ratio of death of 0.90 (95% CI 0.85-0.94, p<0.0001), corresponding to an absolute survival benefit of 4% at 2 and 5 years in favour of chemotherapy. There was no significant benefit associated with adjuvant or neoadjuvant chemotherapy. Chemotherapy given concomitantly to radiotherapy gave significant benefits, but heterogeneity of the results prohibits firm conclusions. Meta-analysis of six trials (861 patients) comparing neoadjuvant chemotherapy plus radiotherapy with concomitant or alternating radiochemotherapy yielded a hazard ratio of 0.91 (0.79-1.06) in favour of concomitant or alternating radiochemotherapy. Three larynx-preservation trials (602 patients) compared radical surgery plus radiotherapy with neoadjuvant chemotherapy plus radiotherapy in responders or radical surgery and radiotherapy in non-responders. The hazard ratio of death in the chemotherapy arm as compared with the control arm was 1.19 (0.97-1.46). INTERPRETATION Because the main meta-analysis showed only a small significant survival benefit in favour of chemotherapy, the routine use of chemotherapy is debatable. For larynx preservation, the non-significant negative effect of chemotherapy in the organ-preservation strategy indicates that this procedure must remain investigational.

Abstract
Many of the cells in solid tumors are hypoxic. This makes them resistant to killing by both radiotherapy and most commonly used anticancer drugs. The resistance towards anticancer drugs is because hypoxia induces a non-proliferative state as well as the fact that the hypoxic cells are furthest from the blood vessels in the tumor (and hence the source of drug). However, a new class of drugs - hypoxic cytotoxins can, by killing these hypoxic cells, not only overcome this resistance, but also exploit hypoxia thereby converting it into a therapeutic advantage. The first drug to be tested in the clinic purely for its activity towards hypoxic cells, tirapazamine, is described. Copyright 2000 Harcourt Publishers Ltd.
