Abstract
BACKGROUND Oral cavity and oropharyngeal cancers are the most common cancers arising in the head and neck. Treatment of oral cavity cancer is generally surgery followed by radiotherapy, whereas oropharyngeal cancers, which are more likely to be advanced at the time of diagnosis, are managed with radiotherapy or chemoradiation. Surgery for oral cancers can be disfiguring and both surgery and radiotherapy have significant functional side effects. The development of new chemotherapy agents, new combinations of agents and changes in the relative timing of surgery, radiotherapy, and chemotherapy treatments may potentially bring about increases in both survival and quality of life for this group of patients. This review updates one last published in 2011. OBJECTIVES To determine whether chemotherapy, in addition to radiotherapy and/or surgery for oral cavity and oropharyngeal squamous cell carcinoma results in improved overall survival, improved disease-free survival and/or improved locoregional control, when incorporated as either induction therapy given prior to locoregional treatment (i.e. radiotherapy or surgery), concurrent with radiotherapy or in the adjuvant (i.e. after locoregional treatment with radiotherapy or surgery) setting. SEARCH METHODS An information specialist searched 4 bibliographic databases up to 15 September 2021 and used additional search methods to identify published, unpublished and ongoing studies. SELECTION CRITERIA We included randomised controlled trials (RCTs) where more than 50% of participants had primary tumours in the oral cavity or oropharynx, and that evaluated the addition of chemotherapy to other treatments such as radiotherapy and/or surgery, or compared two or more chemotherapy regimens or modes of administration. DATA COLLECTION AND ANALYSIS For this update, we assessed the new included trials for their risk of bias and at least two authors extracted data from them. Our primary outcome was overall survival (time to death from any cause). Secondary outcomes were disease-free survival (time to disease recurrence or death from any cause) and locoregional control (response to primary treatment). We contacted trial authors for additional information or clarification when necessary. MAIN RESULTS We included 100 studies with 18,813 participants. None of the included trials were at low risk of bias. For induction chemotherapy, we reported the results for contemporary regimens that will be of interest to clinicians and people being treated for oral cavity and oropharyngeal cancers. Overall, there is insufficient evidence to clearly demonstrate a survival benefit from induction chemotherapy with platinum plus 5-fluorouracil prior to radiotherapy (hazard ratio (HR) for death 0.85, 95% confidence interval (CI) 0.70 to 1.04, P = 0.11; 7427 participants, 5 studies; moderate-certainty evidence), prior to surgery (HR for death 1.06, 95% CI 0.71 to 1.60, P = 0.77; 198 participants, 1 study; low-certainty evidence) or prior to concurrent chemoradiation (CRT) with cisplatin (HR for death 0.71, 95% CI 0.37 to 1.35, P = 0.30; 389 participants, 2 studies; low-certainty evidence). There is insufficient evidence to support the use of an induction chemotherapy regimen with cisplatin plus 5-fluorouracil plus docetaxel prior to CRT with cisplatin (HR for death 1.08, 95% CI 0.80 to 1.44, P = 0.63; 760 participants, 3 studies; low-certainty evidence). There is insufficient evidence to support the use of adjuvant chemotherapy over observation only following surgery (HR for death 0.95, 95% CI 0.73 to 1.22, P = 0.67; 353 participants, 5 studies; moderate-certainty evidence). Among studies that compared post-surgical adjuvant CRT, as compared to post-surgical RT, adjuvant CRT showed a survival benefit (HR 0.84, 95% CI 0.72 to 0.98, P = 0.03; 1097 participants, 4 studies; moderate-certainty evidence). Primary treatment with CRT, as compared to radiotherapy alone, was associated with a reduction in the risk of death (HR for death 0.74, 95% CI 0.67 to 0.83, P < 0.00001; 2852 participants, 24 studies; moderate-certainty evidence). AUTHORS' CONCLUSIONS: The results of this review demonstrate that chemotherapy in the curative-intent treatment of oral cavity and oropharyngeal cancers only seems to be of benefit when used in specific circumstances together with locoregional treatment. The evidence does not show a clear survival benefit from the use of induction chemotherapy prior to radiotherapy, surgery or CRT. Adjuvant CRT reduces the risk of death by 16%, as compared to radiotherapy alone. Concurrent chemoradiation as compared to radiation alone is associated with a greater than 20% improvement in overall survival; however, additional research is required to inform how the specific chemotherapy regimen may influence this benefit.

[PMID: 33515668 DOI: 10.1016/j.radonc.2021.01.013] [Citation(s) in RCA: 148] [Impact Index Per Article: 49.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/15/2020] [Revised: 12/22/2020] [Accepted: 01/08/2021] [Indexed: 02/07/2023]
Abstract
BACKGROUND AND PURPOSE The Meta-Analysis of Chemotherapy in squamous cell Head and Neck Cancer (MACH-NC) demonstrated that concomitant chemotherapy (CT) improved overall survival (OS) in patients without distant metastasis. We report the updated results. MATERIALS AND METHODS Published or unpublished randomized trials including patients with non-metastatic carcinoma randomized between 1965 and 2016 and comparing curative loco-regional treatment (LRT) to LRT + CT or adding another timing of CT to LRT + CT (main question), or comparing induction CT + radiotherapy to radiotherapy + concomitant (or alternating) CT (secondary question) were eligible. Individual patient data were collected and combined using a fixed-effect model. OS was the main endpoint. RESULTS For the main question, 101 trials (18951 patients, median follow-up of 6.5 years) were analyzed. For both questions, there were 16 new (2767 patients) and 11 updated trials. Around 90% of the patients had stage III or IV disease. Interaction between treatment effect on OS and the timing of CT was significant (p < 0.0001), the benefit being limited to concomitant CT (HR: 0.83, 95%CI [0.79; 0.86]; 5(10)-year absolute benefit of 6.5% (3.6%)). Efficacy decreased as patients age increased (p_trend = 0.03). OS was not increased by the addition of induction (HR = 0.96 [0.90; 1.01]) or adjuvant CT (1.02 [0.92; 1.13]). Efficacy of induction CT decreased with poorer performance status (p_trend = 0.03). For the secondary question, eight trials (1214 patients) confirmed the superiority of concomitant CT on OS (HR = 0.84 [0.74; 0.95], p = 0.005). CONCLUSION The update of MACH-NC confirms the benefit and superiority of the addition of concomitant CT for non-metastatic head and neck cancer.

Abstract
Treatment is complex for patients with head and neck (H&N) cancers with specific site of disease, stage, and pathologic findings guiding treatment decision-making. Treatment planning for H&N cancers involves a multidisciplinary team of experts. This article describes supportive care recommendations in the NCCN Guidelines for Head and Neck Cancers, as well as the rationale supporting a new section on imaging recommendations for patients with H&N cancers. This article also describes updates to treatment recommendations for patients with very advanced H&N cancers and salivary gland tumors, specifically systemic therapy recommendations.

Abstract
Background The aim of the study was to investigate how the expression of tumor markers p21, p27, p53, cyclin D1, EGFR, Ki-67, and CD31 influenced the outcome of advanced inoperable oropharyngeal carcinoma patients, treated with concomitant radiochemotherapy. Patients and methods. The pretreatment biopsy specimens of 74 consecutive patients with inoperable stage IV oropharyngeal squamous cell carcinoma treated with concomitant radiochemotherapy were in retrospective study processed by immunochemistry for p21, p27, p53, cyclin D1, EGFR, Ki-67, and CD31. Disease-free survival (DFS) was assessed according to the expression of tumor markers. Results Patients with a high expression of p21 (≥10%), p27 (>50%), Ki-67 (>50%), CD31 (>130 vessels/mm2) and low expression of p53 (<10%), cyclin D1 (<10%) and EGFR (<10%) (favorable levels - FL) had better DFS than patients with a low expression of p21 (<10%), p27 (≤50%), Ki-67 (≤50%), CD31 (<130 vessels/mm2) and high expression of p53 (≥10%), cyclin D1 (≥10%) and EGFR (≥10%) (unfavorable levels - UL). However, statistical significance in survival between FL and UL was achieved only for p27 and cyclin D1. DFS significantly decreased with an increasing number of markers with an unfavorable level per tumor (1–4 vs. 5–7) (78% vs. 32%, respectively; p = 0.004). The number of markers per tumor with UL of expression retained prognostic significance also in multivariate analysis. Conclusions Statistical significance in survival between FL and UL emerged only for p27 and cyclin D1. The number of markers per tumor with UL of expression was an independent prognostic factor for an adverse outcome.

Abstract
BACKGROUND Oral cavity and oropharyngeal cancers are frequently described as part of a group of oral cancers or head and neck cancer. Treatment of oral cavity cancer is generally surgery followed by radiotherapy, whereas oropharyngeal cancers, which are more likely to be advanced at the time of diagnosis, are managed with radiotherapy or chemoradiation. Surgery for oral cancers can be disfiguring and both surgery and radiotherapy have significant functional side effects, notably impaired ability to eat, drink and talk. The development of new chemotherapy agents, new combinations of agents and changes in the relative timing of surgery, radiotherapy, and chemotherapy treatments may potentially bring about increases in both survival and quality of life for this group of patients. OBJECTIVES To determine whether chemotherapy, in addition to radiotherapy and/or surgery for oral cavity and oropharyngeal cancer results in improved survival, disease free survival, progression free survival, locoregional control and reduced recurrence of disease. To determine which regimen and time of administration (induction, concomitant or adjuvant) is associated with better outcomes. SEARCH STRATEGY Electronic searches of the Cochrane Oral Health Group's Trials Register, CENTRAL, MEDLINE, EMBASE, AMED were undertaken on 1st December 2010. Reference lists of recent reviews and included studies were also searched to identify further trials. SELECTION CRITERIA Randomised controlled trials where more than 50% of participants had primary tumours in the oral cavity or oropharynx, and which compared the addition of chemotherapy to other treatments such as radiotherapy and/or surgery, or compared two or more chemotherapy regimens or modes of administration, were included. DATA COLLECTION AND ANALYSIS Eighty-nine trials which met the inclusion criteria were assessed for risk of bias and data were extracted by two or more review authors. The primary outcome was total mortality. Trial authors were contacted for additional information or for clarification. MAIN RESULTS There is evidence of a small increase in overall survival associated with induction chemotherapy compared to locoregional treatment alone (25 trials), hazard ratio (HR) of mortality 0.92 (95% confidence interval (CI) 0.84 to 1.00, P = 0.06). Post-surgery adjuvant chemotherapy is associated with improved overall survival compared to surgery ± radiotherapy alone (10 trials), HR of mortality 0.88 (95% CI 0.79 to 0.99, P = 0.03), and there is some evidence that this improvement may be greater with concomitant adjuvant chemoradiotherapy (4 trials), HR of mortality 0.84 (95% CI 0.72 to 0.98, P = 0.03). In patients with unresectable tumours, there is evidence that concomitant or alternating chemoradiotherapy is associated with improved survival compared to radiotherapy alone (26 trials), HR of mortality 0.78 (95% CI 0.73 to 0.83, P < 0.00001). These findings are confirmed by sensitivity analyses based on studies assessed at low risk of bias. There is insufficient evidence to identify which agent(s) and/or regimen(s) are the most effective. The additional toxicity attributable to chemotherapy in the combined regimens remains unquantified. AUTHORS' CONCLUSIONS Chemotherapy, in addition to radiotherapy and surgery, is associated with improved overall survival in patients with oral cavity and oropharyngeal cancers. Induction chemotherapy may prolong survival by 8 to 20% and adjuvant concomitant chemoradiotherapy may prolong survival by up to 16%. In patients with unresectable tumours, concomitant or alternating chemoradiotherapy may prolong survival by 10 to 22%. There is insufficient evidence as to which agent or regimen is most effective and the additional toxicity associated with chemotherapy given in addition to radiotherapy and/or surgery cannot be quantified.

SEARCH STRATEGY Electronic searches of the Cochrane Oral Health Group's Trials Register, CENTRAL, MEDLINE, EMBASE, AMED were undertaken on 28th July 2010. Reference lists of recent reviews and included studies were also searched to identify further trials. SELECTION CRITERIA Randomised controlled trials where more than 50% of participants had primary tumours in the oral cavity or oropharynx, and which compared the addition of chemotherapy to other treatments such as radiotherapy and/or surgery, or compared two or more chemotherapy regimens or modes of administration, were included. DATA COLLECTION AND ANALYSIS Trials which met the inclusion criteria were assessed for risk of bias using six domains: sequence generation, allocation concealment, blinding, completeness of outcome data, selective reporting and other possible sources of bias. Data were extracted using a specially designed form and entered into the characteristics of included studies table and the analysis sections of the review. The proportion of participants in each trial with oral cavity and oropharyngeal cancers are recorded in Additional Table 1. MAIN RESULTS There was no statistically significant improvement in overall survival associated with induction chemotherapy compared to locoregional treatment alone in 25 trials (hazard ratio (HR) of mortality 0.92, 95% confidence interval (CI) 0.84 to 1.00). Post-surgery adjuvant chemotherapy was associated with improved overall survival compared to surgery +/- radiotherapy alone in 10 trials (HR of mortality 0.88, 95% CI 0.79 to 0.99), and there was an additional benefit of adjuvant concomitant chemoradiotherapy compared to radiotherapy in 4 of these trials (HR of mortality 0.84, 95% CI 0.72 to 0.98). Concomitant chemoradiotherapy resulted in improved survival compared to radiotherapy alone in patients whose tumours were considered unresectable in 25 trials (HR of mortality 0.79, 95% CI 0.74 to 0.84). However, the additional toxicity attributable to chemotherapy in the combined regimens remains unquantified. AUTHORS' CONCLUSIONS Chemotherapy, in addition to radiotherapy and surgery, is associated with improved overall survival in patients with oral cavity and oropharyngeal cancers. Induction chemotherapy is associated with a 9% increase in survival and adjuvant concomitant chemoradiotherapy is associated with a 16% increase in overall survival following surgery. In patients with unresectable tumours, concomitant chemoradiotherapy showed a 22% benefit in overall survival compared with radiotherapy alone.

Abstract
PURPOSE To evaluate the toxicity and efficacy of concomitant chemoradiotherapy with mitomycin C and cisplatin in the treatment of advanced unresectable squamous cell carcinoma of the head and neck. PATIENTS AND METHODS Treatment consisted of conventional radiotherapy (70 Gy in 35 fractions), mitomycin C 15 mg/m(2) IV, applied after the delivery of 10 Gy, and cisplatin at an initial dose of 10 mg/m(2)/d IV, applied during the last 10 fractions of irradiation ("chemoboost"). The cisplatin dose was escalated with respect to the toxic side effects by 2 mg/m(2)/d up to the maximum tolerated dose (MTD) or at the most 14 mg/m(2)/d (Phase I study), which was tested in the subsequent Phase II study. RESULTS All 36 patients had Stage T4 and/or N3 disease, and the majority had oropharyngeal (50%) or hypopharyngeal (39%) primary tumors. Six patients were treated at each of the three cisplatin dose levels tested (Phase I study). Dose-limiting toxicity was not reached even at 14 mg/m(2)/d of cisplatin, which was determined as the MTD and tested in an additional 18 patients (Phase II study). After a median follow-up time of 48 months, 4-year locoregional control, failure-free, and overall survival rates were 30%, 14%, and 20%, respectively. In 24 patients treated at the cisplatin dose level of 14 mg/m(2)/d, the corresponding rates were 40%, 20%, and 22%, respectively. CONCLUSION Concomitant chemoradiotherapy with mitomycin C and cisplatin "chemoboost" at 14 mg/m(2)/d is feasible, with encouraging survival results if the extremely poor disease profile of the treated patients is considered.

Abstract
AbstractIntroduction:Currently, concomitant chemoradiation using cisplatin is one of the standards of care for the management of head and neck cancer, but at the cost of increased acute toxicity. Our aim was to assess whether vinorelbine was less toxic and of at least comparable efficacy, if not better, compared with cisplatin.Materials and methods:A total of 72 patients with squamous cell carcinoma in the head and neck region were recruited, 40 in arm A and 32 in arm B. Patients in arm A received 40 mg/m2 cisplatin weekly. Patients in arm B received 6 mg/m2 vinorelbine weekly. Both arms also received 66 Gy of radiation in conventional fractionation.Results and analysis:There was no statistically significant difference in response rate or toxicities between the two arms, except for nausea and/or vomiting, which was significantly less frequent in the vinorelbine arm.Conclusion:Vinorelbine was as effective as cisplatin in controlling locoregional disease in locally advanced head and neck cancer, but was only marginally less toxic than cisplatin.

Abstract
In this article, we use the example of head and neck cancer to show how concurrent chemoradiotherapy is used to treat a cancer where locoregional control is central for treatment success. The advent of concurrent chemoradiation has significantly contributed to the curability of head and neck cancer, including locoregionally advanced disease. Preserving organ function and reducing toxic effects are increasingly the focus of clinical trials. We review the available chemoradiotherapy platforms used for head and neck cancer, with initial discussions focused on single-agent cytotoxic-based regimens. We then assess the literature on multiagent-based regimens and include a discussion of the integration of novel agents, such as EGFR inhibitors, and antiangiogenic drugs into treatment platforms. Although single-agent cisplatin-based chemoradiotherapy is still widely used as a standard therapy, we propose that evidence increasingly shows that multiagent-based chemoradiotherapy, and EGFR-inhibitor-based treatments, offer distinct advantages. We provide guidance for clinicians based on current clinical trial evidence on how to choose appropriate treatment platforms for their patients.

Abstract
BACKGROUND The current study was conducted to characterize the risks and clinical consequences of oral mucositis (OM) in patients with head and neck carcinoma (HNC) who are receiving radiation therapy. METHODS Data regarding 450 HNC patients who had received radiation therapy were collected via chart review from 154 U.S. medical and radiation oncologists. Information obtained included patient characteristics, treatments received, highest recorded grade of OM during radiation therapy (none, mild, moderate, or severe), and outcomes potentially associated with mucosal injury. RESULTS The mean age (+/- standard deviation [SD]) of the study subjects was 61.3 years (12.3 yrs); the majority of patients (80%) were men. Primary tumor locations included the oropharynx (26.4%), larynx (26.4%), oral cavity including the lip (24.4%), hypopharynx (13.6%), and nasopharynx (9.1%). The majority of tumors were new and were classified as AJCC Stages III or IV. The majority of patients (83%) received standard radiation therapy; the mean (+/- SD) cumulative dose was 6285 centigrays (cGy) (+/- 1158 cGy). Approximately 33% of the patients received concomitant chemotherapy. The majority of patients (83%) developed OM; 29% developed severe OM. Patients with severe OM were more likely to have nasopharyngeal or oropharyngeal tumors (adjusted odds ratio [OR] of 10.1 [95% confidence interval (95% CI), 2.1-49.9] and 6.9 [95% CI, 2.4-19.7], respectively), and to have received cumulative radiation doses > 5000 cGy (OR of 10.4; 95% CI, 2.9-37.1) and concomitant chemotherapy (OR of 3.3; 95% CI, 1.4-8.0). Patients with OM had more unplanned breaks in radiation therapy (OR of 3.8; 95% CI, 1.7-8.5) and hospital admissions (OR of 3.5; 95% CI, 1.3-9.5). CONCLUSIONS HNC patients with nasopharyngeal or oropharyngeal tumors, and those who receive cumulative radiation doses > 5000 cGy or concomitant chemotherapy, are more likely to develop OM. Patients with OM are at a higher risk of unplanned breaks in radiation therapy and hospitalization.

Abstract
BACKGROUND Radiotherapy is often the primary treatment for advanced head and neck cancer, but the rates of locoregional recurrence are high and survival is poor. The purpose of this study was to evaluate the efficacy and toxicity of split-course radiotherapy combined with concurrent carboplatin chemotherapy after long-term follow-up. PATIENTS AND METHODS From August 1987 to May 1994, 66 patients (54 males, 12 females, mean age 58 years) with advanced inoperable oropharynx cancer were treated at the University of Göttingen, Göttingen, Germany. Tumour localization in the oropharynx was: tonsil (n = 33), base of tongue (n = 28), soft palate (n = 2) and posterior pharyngeal wall (n = 3). Forty-nine patients presented with a T(4) tumour, 15 were T(3) and 2 were T(2). The nodal status was distributed as follows: N0 (n = 7), N1 (n = 5), N2 (n = 28) and N3 (n = 26). A total radiation dose of 5,670 cGy was applied in 6 weeks as a split-course regimen (2 x 2.1 Gy/day, 4 times a week, weeks 1 and 2 and weeks 5 and 6). Concomitant carboplatin chemotherapy was given each radiotherapy day before irradiation (50 mg/m(2)). RESULTS In December 2003, 12 patients were still alive. Survivors have reached a maximum follow-up of 170.5 months (median 14.3 months). Two- and 5-year overall survival was 32 and 18%, 2-year disease-free survival 27%. Therapy was tolerated moderately (19% grade 3 skin reaction, 26% grade 3 mucositis, 23% grade 3 xerostomia, 20% grade 3 leucopenia, 8% grade 3 thrombopenia and 25% grade 3 anaemia). CONCLUSION Split-course radiotherapy and concomitant carboplatin chemotherapy can be carried out in inoperable head and neck cancer without severe toxicity. After long-term follow-up, survival rates are unfavourable in this poor prognostic group of patients.

Abstract
PURPOSE A phase I trial to evaluate the maximum tolerated dose (MTD) of continuous mitomycin-C infusion in radiochemotherapy of inoperable HNSCC. METHODS Twenty-one patients were treated with 70 Gy (2 Gy/day) and simultaneous chemotherapy (5-FU 600 mg/m2/day and MMC, both as continuous infusion on days 1-5 and 36-40. The MMC dose was dependent on dose escalation levels I-IV: 2/2.6/3.2/4 mg/m2/day. RESULTS Dose limiting toxicity (DLT) (grade 3 mucositis and/or dysphagia) occurred at dose level IV (MMC 4 mg/m2/day). Accordingly, dose escalation level III (MMC 3.2 mg/m2/day) was set as the MTD. One and 2-year survival rate: 66.7 and 29.5%, disease free survival: 47.6 and 22.8%, respectively. CONCLUSIONS Our study demonstrates that continuous infusion of 5-FU/MMC can be safely administered at a MMC dose of 3.21 mg/m2/day on days 1-5 and 36-40 in concomitant radiochemotherapy. A phase II study should be initiated to establish the role of this regimen in the treatment of head and neck cancer.

Abstract
PURPOSE Previous randomized trials have shown a benefit with concurrent use of the hypoxic cell cytotoxin mitomycin C (MC) and radiation (RT) in the management of squamous cell cancer of the head and neck (SCCHN). We conducted a randomized trial comparing MC with porfiromycin (POR) in combination with RT in the management of SCCHN. METHODS AND MATERIALS Between 1992 and 1999, 128 patients with SCCHN were enrolled in this prospective randomized trial. Patients were stratified by management intent, and balanced with respect to stage and site of disease. They were randomized to receive MC (15 mg/M(2)) or POR (40 mg/M(2)) on Days 5 and 47 (or last day) of RT. Of 121 evaluable patients, 61 were randomized to MC and 60 to POR. Patients were treated with standard daily RT to a total median dose of 64 Gy over 47 days. Patients were well balanced with respect to management intent, stage, site, age, sex, hemoglobin levels, tumor grade, radiation dose, and days on treatment. RESULTS There were no significant differences between the two arms with respect to acute hematologic or nonhematologic toxicities. As of January 2003 with a median follow-up of 6.3 years, there have been 19 local relapses (4 MC vs. 15 POR), 21 regional relapses (7 MC vs. 14 POR), 24 distant metastases (11 MC vs. 13 POR), and 66 deaths (33 MC vs. 33 POR). MC was superior to POR with respect to 5-year local relapse-free survival (91.6% vs. 72.7%, p = 0.01), local-regional relapse-free survival (82% vs. 65.3%, p = 0.05), and disease-free survival (72.8% vs. 52.9%, p = 0.026). There were no significant differences between the two arms with respect to overall survival (49.2% vs. 54.4%) or distant metastasis-free rate (79.9% vs. 75.9%). CONCLUSIONS Despite promising preclinical data, and an acceptable toxicity profile, POR was inferior to MC as an adjunct to RT in the management of SCCHN. This randomized trial emphasizes the need for randomized studies to evaluate new agents in the management of SCCHN.

Abstract
BACKGROUND The purpose of this study was to evaluate the efficacy and toxicity of radiotherapy and concomitant 5-fluorouracil (5-FU) and mitomycin-C infusion in inoperable head and neck cancer. METHODS Seventy-six patients (86% men, 14% women), mean age 57 years, with primary inoperable head and neck cancer were treated with 70 Gy plus simultaneous intravenous chemotherapy with 5-FU (600 mg/m(2)/d, days 1 to 5) and mitomycin-C (10 mg/m(2), day 5 plus 36). RESULTS After a mean follow-up of 13 months, 31 patients were alive. Complete response (CR) was seen in 63%. The 1- and 2-year overall survival rates were 67.7% and 39.5%, and locoregional control rates were 51.7% and 35.6%. Pretreatment hemoglobin <13.9 g/dL was associated with lower locoregional control rates (p = .03). Therapy was well tolerated (grade 3 mucositis in 21%, grade 4 in 1%, grade 3 leukopenia in 11%). CONCLUSIONS Our radiochemotherapy regimen offers a curative option for this group of patients with a poor prognosis. Hemoglobin levels before therapy have an influence on prognosis.

Abstract
Squamous cell head and neck cancer is a relatively uncommon malignancy in North America. Nonetheless, it has been of considerable interest to medical oncologists because of its remarkable sensitivity to systemic chemotherapy. Even in patients with relapsed or metastatic disease, meaningful tumour shrinkage can be achieved with systemic therapy. This has led to the performance of carefully conducted clinical trials exploring the role of systemic chemotherapy, not only in the palliative setting, but as part of definitive multi-modality treatment. Chemotherapy has been used as the initial (or induction) treatment, as an adjuvant treatment after definitive surgery and/or radiation, and concurrent with both definitive and adjuvant radiation therapy. Evidence-based conclusions have been drawn from these clinical trials and have led to significant changes in the current standards of care for this disease. In this article, the available data supporting the use of systemic chemotherapy as palliative treatment, and as part of the definitive management for this disease will be reviewed.

Abstract
PURPOSE In a prospective randomized clinical study, simultaneous postoperative application of irradiation (RT), mitomycin C, and bleomycin was tested in a group of patients with operable advanced head-and-neck carcinoma. It was expected that the planned combined postoperative therapy would reduce the number of locoregional recurrences and prolong survival. METHODS AND MATERIALS A total of 114 eligible patients with Stage III or IV squamous cell head-and-neck carcinoma were randomized to receive postoperative RT alone (Group 1) or RT combined with simultaneous mitomycin C and bleomycin (Group 2). Patients were stratified according to the stage and site of the primary tumor and the presence or absence of high-risk prognostic factors. Primary surgical treatment was performed with curative intent in all patients. Patients in both groups were postoperatively irradiated to the total dose of 56-70 Gy. Chemotherapy included mitomycin C 15 mg/m(2) after 10 Gy and 5 mg of bleomycin twice a week during RT to the planned total dose of 70 mg. RESULTS At 2 years, patients in the radiochemotherapy group had better locoregional control (86%) than those in the RT alone group (69%; p = 0.037). Disease-free survival and overall survival was also better in the radiochemotherapy group compared with the RT-alone group (76% vs. 60%, p = 0.099; and 74% vs. 64%, p = 0.036, respectively). Patients who benefited from chemotherapy were those with high-risk factors. CONCLUSION The results of the present study indicate that concomitant postoperative radiochemotherapy with mitomycin C and bleomycin improves locoregional control and survival in patients with advanced head-and-neck carcinoma. The patients who benefited from chemotherapy were those with high-risk factors.

Abstract
Since the publication of the Veterans Affairs study in the early 1990s, much has been learned regarding the role of chemotherapy, radiation therapy, and more importantly, the role of combined-modality treatment with chemoradiation in the therapy of locally advanced head and neck cancer. There continues to be widespread variation and controversy in the timing, schedule, and intensity of chemotherapy and chemoradiation. Herein, we present the various approaches currently used in the year 2003 with a specific emphasis on the role of sequential combined-modality therapy combining chemotherapy, chemoradiotherapy, and surgery in the treatment of these malignancies.

Abstract
BACKGROUND An intensified treatment regimen for previously untreated Stage III and IV resectable oral cavity, oropharyngeal, or hypopharyngeal squamous cell carcinoma was analyzed to assess disease control, patient compliance, and toxicity. METHODS Forty three patients with previously untreated, advanced, resectable squamous cell carcinoma of the oral cavity, oropharynx, or hypopharynx were enrolled in a prospective Phase II institutional clinical trial at a tertiary care comprehensive cancer center. This regimen was a continuum of multimodal treatment in a contracted time interval. It included preoperative slightly accelerated hyperfractionated radiotherapy with concurrent cisplatin, followed immediately with surgery and intraoperative radiotherapy, and completed with early postoperative weekly paclitaxel (beginning on Day 6 after surgery), two additional cisplatin cycles, and concurrent once daily radiotherapy beginning on Day 28 after surgery. RESULTS The current trial was designed to reduce the toxicity of the systemic therapy while maintaining or improving locoregional/distant disease control and patient compliance. There were 43 patients enrolled, and the range of time at risk was 2.6 to 24.7 months (median, 14.6 months). Of the 43 registered patients, 43 were evaluable. The locoregional (100%) and systemic (93%) disease control rates were excellent, with low rates of patient noncompliance (21%) and reduced levels of toxicity. CONCLUSIONS An intensive treatment regimen that improves disease control and treatment compliance is clearly feasible for this patient population. Future plans include modifications to continue to reduce toxicity and expansion to a multi-center Phase II trial to determine if the single institutional results can be duplicated.

Abstract
BACKGROUND The standard of care for locally advanced head and neck carcinoma usually has been surgery followed by radiation therapy. Patient survival using this approach has been reported to be poor. The disfiguration resulting from surgery and the long-term morbidity of postoperative radiation often results in considerable distress. Concurrent chemotherapy and radiation was introduced to improve outcome. Excellent local control and survival results often have been reported in Phase II and Phase III studies. The acute toxicity of combined chemotherapy and radiation is significant. However, organ preservation may improve quality of life. This review article summarizes the findings from published series of surgery, postoperative radiation, radiation therapy alone, and chemoradiation with regard to quality of life issues for patients with locally advanced head and neck carcinoma. METHODS A literature search was used to identify quality-of-life studies of postoperative radiation, radiation therapy alone, and chemoradiation in patients with locally advanced head and neck carcinoma. Factors affecting long-term quality-of-life issues in each treatment modality were identified, compared, and evaluated. RESULTS Speech disorder, dysphagia, pain, and depression were found to be the common side effects affecting quality of life regardless of the treatment modality. Xerostomia is the major complication affecting patients undergoing radiation or chemoradiation. CONCLUSIONS Acute side effects of combined chemotherapy and radiation therapy usually were found to resolve after treatment. Long-term morbidity is substantial because of xerostomia and severe dysphagia. However, preliminary studies suggest that because of organ preservation, patients may achieve a better quality of life after chemoradiation compared with the conventional use of surgery and postoperative radiation.

Abstract
BACKGROUND A systematic review was conducted to develop clinical recommendations for concomitant chemotherapy (CT) and radiotherapy (RT) in patients with locally advanced squamous cell head and neck cancer (SCHNC). METHODS Results of published randomized controlled trials (RCTs) were pooled using Meta-analyst(0.988) software. RESULTS A pooled analysis of 18 RCTs (20 comparisons) involving 3,192 patients detected a reduction in mortality for concomitant therapy compared with RT alone (odds ratio [OR], 0.62; 95% confidence interval [CI], 0.52-0.74; relative risk, 0.83; risk reduction, 11%; p < .00001). Platinum-based regimens involving 1,514 patients from nine trials (10 comparisons) were most effective (OR, 0.57; 95% CI, 0.46-0.71; p < .00001; risk reduction, 12%). Concomitant therapy produced more acute adverse effects than RT alone. CONCLUSION Platinum-based concomitant CT and RT is superior to conventional RT alone in improving survival in locally advanced SCHNC. Subgroup analyses can be used to help in choosing the most appropriate concomitant regimen.

Abstract
From February 1993 through July 1994, 37 patients with stage III-IV squamous cell carcinomas of the oral cavity, oropharynx, or hypopharynx (stage II-IV) were registered to a treatment regimen consisting of preoperative continuous infusion cisplatin (80 mg/m2/80 hours) with hyperfractionated external beam radiotherapy (9.1 Gy/7 fractions of 1.3 Gy BID), surgical resection, intraoperative radiotherapy (7.5 Gy), and postoperative radiotherapy (40 Gy) with concurrent cisplatin (100 mg/m2 x 2 courses). The objectives of the regimen were to improve patient compliance while also increasing treatment intensity. The purpose of this article is to report the local, regional (nodal), and distant disease control of these patients after an extended time at risk (median 40 months). Overall compliance (73%), local control at primary site (97%), and regional nodal control (95%) were excellent. The rate of distant metastasis was 19%. Absolute survival at 48 months was 45.9%.

PURPOSE To investigate the influence of carbogen breathing on chemoradiation and the effects of erythropoietin on transfusions. METHODS AND MATERIALS From March 1996 to April 2000, 42 (4 Stage III and 38 Stage IV) patients with head and neck cancer were treated with a twice-a-day hyperfractionated schedule. Each fraction consisted of 5 mg/m(2) of carboplatin plus 115 cGy with carbogen breathing. Treatment was given 5 days per week up to total doses of 350 mg/m(2) of carboplatin plus 8050 cGy in 7 weeks. Anemia was treated either by transfusion or by erythropoietin. RESULTS Forty-one patients tolerated the treatment as scheduled. All patients tolerated the planned radiation dose. Five transfusions were given in the first group, but no transfusion was needed in the erythropoietin group. Local toxicities remained at the level expected with irradiation alone. Chemotherapy toxicity was moderate. Forty-two complete responses were achieved. At two years actuarial local control, cause-specific survival and overall survival are respectively 85%, 69%, and 68%. At four years estimated probabilities of local control, cause-specific survival and overall survival are also 85%, 69%, and 68%. CONCLUSIONS These results compare favorably with those of most reported studies. The addition of carbogen breathing appears to improve the results of chemoradiation alone. Erythropoietin therapy avoided transfusions.

Abstract
The feasibility and effectiveness of a combined chemoradiotherapy treatment modality for locally advanced head and neck cancer was tested in a phase II trial. From March 1995 to June 1998, 35 patients with advanced squamous cell carcinoma of the head and neck were treated with a continuous intravenous infusion of 5-fluorouracil (600 mg m-2 24 h-1 for Days 1 to 5 (120 h)) and mitomycin-C (10 mg m-2 intravenously) on Day 5 during the first week of radiotherapy and on Day 36. 31 patients had stage IV disease; 4 patients had stage III; and 1 patient had stage II. Patient ages ranged from 42-69 years (median 56.7 years). The tumours involved were as follows: oral cavity (n = 11); oropharynx (n = 14); hypopharynx/larynx (n = 10). Radiotherapy was delivered to a total dose of 70 Gy with conventional fractionation (2 Gy per fraction, five times a week). Chemotherapy was well tolerated and all patients received the intended dose. Mild nausea occurred in five patients. After a mean follow-up of 21 months (range 10-44 months), 8 (23%) patients remain alive. A complete response was seen in 28 (80%) patients. When a recurrence appeared, it was within the first year after treatment. 1- and 2-year overall survival rates were 46% and 23%, respectively. Grade 3 mucositis occurred in 17% of patients. Grade 1-2 thrombopaenia occurred in 3 (9%) patients, grade > 2 leukopaenia in 4 (11%) patients, and grade > or = 2 anaemia in 3 (9%) patients. We observed a treatment interruption of maximum 1 week for six patients owing to mucositis. Febrile neutropaenia or aplasia were not observed. The concomitant use of 5-fluorouracil, mitomycin-C and radiotherapy in locally advanced head and neck carcinoma is well tolerated in this group of patients. This protocol showed good locoregional response with a very low toxicity profile.

Abstract
Head and neck squamous cell carcinoma (HNSCC) is an aggressive epithelial malignancy that is now the sixth most common neoplasm in the world today. Approximately 50,000 cases in the United States and more than 500,000 cases worldwide will be diagnosed in 2000 [1]. Despite numerous advances in treatment utilising the most recent protocols for surgery, radiation and chemotherapy, the long-term survival has remained at less than 50% over the past 40 years [2]. This poor long-term survival is due to a number of variables including delayed diagnosis as well as the frequent development of multiple primary tumours. Therefore, in addition to early detection, continued emphasis must be placed on preventing the development of new primaries as well as establishing more effective treatments for individuals who present with advanced disease. This review will summarise some of the recent advances in the realms of chemotherapy and radiation therapy. In addition, it will discuss the present status of chemoprevention in HNSCC. Finally, we will discuss the rationale for the use of anti-angiogenic agents as one possible means of developing new chemopreventive protocols that result in reduced toxicity while maintaining similar clinical efficacies.

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

Abstract
The concurrent use of chemotherapy with radiation in the management of head and neck cancer has been shown in several randomized studies and two recent meta-analyses to result in statistically and clinically significant gains in locoregional control and overall survival. This article highlights and summarizes the results of selected randomized studies. Concurrent single-agent chemotherapy trials, hypoxic cell sensitizer trials, and multiagent chemotherapy trials are presented. Trials employing concurrent chemoradiation in the postoperative setting, trials employing concurrent chemoradiation with an altered fractionation scheme, and promising results using concurrent chemoradiation in the previously radiated patient are presented. Current ongoing trials and future directions in concurrent chemoradiation are discussed.

Abstract
BACKGROUND Using chemotherapy as a part of each treatment fraction remains unexplored. This study integrates the concomitant administration of carboplatin with hyperfractionated irradiation by optimizing chemopotentiation through carboplatin administration with each irradiation fraction. METHODS From February 1993 to August 1996, 52 patients with advanced head and neck cancer were treated on a twice-a-day chemoradiotherapy schedule. Each fraction consisted of 115 cGy preceded by 5 mg/m2 of carboplatin. Treatment was given 5 days a week up to total doses of 350 mg/m2 of carboplatin + 8050 cGy in 7 weeks. RESULTS All (100%) of patients tolerated the treatment (83% as scheduled). Acute and late toxicities were moderate. Rates of 96% complete response (CR) and 4% partial response (PR) were achieved. At 52 months, local control and cause-specific survival rates are 72% and 59%, respectively. Nodal control rate is 95%. CONCLUSION These results show potential for improvement upon hyperfractionated radiotherapy alone and compare favorably with those of most reported trials.

Abstract
PURPOSE The aim of this phase II study conducted on unresectable squamous cell carcinoma (USCC) of the oro- and hypopharynx was to associate twice-a-day (b.i.d.) continuous nonaccelerated radiotherapy with concomitant cisplatin (CP)-5-fluorouracil (5-FU) chemotherapy, both given at full dose. Feasibility, efficacy, survival, and pharmacokinetic-pharmacodynamic relationships were analyzed. METHODS AND MATERIALS Fifty-four consecutive patients with strictly USCC of oro- and/or hypopharynx received continuous b.i.d. radiotherapy (RT) (2 daily fractions of 1.2 Gy, 5 days a week, with a 6-h minimal interval between fractions). Total RT dose was 80.4 Gy on the oropharynx and 75.6 Gy on the hypopharynx. Three chemotherapy (CT) courses of CP-5-FU were given during RT at 21-day intervals (third not delivered after the end of RT). CP dose was 100 mg/m2 (day 1) and 5-FU was given as 5-day continuous infusion (day 2-day 6: 750 mg/m2/day cycle 1, 750 mg total dose/day cycle 2 and 3). Pharmacokinetics was performed for 5-FU (105 h follow-up) and CP (single sample at 16 h). Special attention was paid to supportive care. RESULTS Good feasibility of RT was observed (85.2% of patients with total dose > 75 Gy). Five patients received 1 CT cycle, 34: 2 cycles, and 15: 3 cycles. The most frequent and severe acute toxicities were mucositis with grade 3-4 occurring in 28% at cycle 1 and 86% at cycle 2, as well as neutropenia (43% at cycle 2). Locoregional control at 6 months was observed in 66.7% of patients. No late toxicity above grade 2 RTOG was noticed. CP dose and 5-FU AUC(0-105h) were significantly linked to grade 3-4 neutropenia (cycle 2). Cumulative total platinum (Pt) concentration and Karnofsky index were the only independent predictors of locoregional control at 6 months. Finally, total RT dose and total Pt concentration were the only independent predictors of specific survival. CONCLUSION This protocol showed good locoregional response with an acceptable toxicity profile. Pharmacokinetic survey is probably an effective approach to further reduce toxicity and improve efficacy. A multicentric randomized phase III study, now underway, should confirm these encouraging results.

Abstract
PURPOSE To compare the efficacy of concomitant irradiation with mitomycin C and bleomycin in patients with inoperable head and neck carcinoma with radiotherapy alone. METHODS AND MATERIALS Between March 1991 and December 1993, 64 patients with inoperable head and neck carcinoma (41 with oropharyngeal site) were randomized to radiotherapy alone (group A) or radiotherapy combined with simultaneous application of mitomycin C and bleomycin (group B). In both groups patients were irradiated five times weekly with 2 Gy to a total dose of 66-70 Gy. The planned concomitant treatment in group B was: bleomycin 5 units twice a week i.m., total dose 70 units, mitomycin C 15 mg/m2 i.v. after delivery of 10 Gy, and 10 mg/m2 i.v. on the last day of radiotherapy. To enhance the effect of these two drugs, patients received also nicotinamide, chlorpromazine, and dicoumarol. Because significantly better results were achieved in arm B for patients with inoperable oropharyngeal carcinoma, the study was closed and such patients were after December 1993 routinely treated with the combined therapy (as in arm B). Until October 1996, we treated and followed up 48 such consecutive patients. RESULTS Median follow-up of our study patients is 42 months. Complete remission (CR) rate in group A was 31% and in group B 59% (p = 0.04); disease-free survival (DFS) in group A was 8% and in group B 37% (P = 0.01); and overall survival (OS) was 7% in group A and 26% in group B (p = 0.08). CR rate for patients with oropharyngeal carcinoma was 29% in group A (N = 21) and 75% in group B (N = 20) (p = 0.007); DFS in group A was 10% and in group B 48% (p = 0.001); and the OS was 10% in group A and 38% in group B (p = 0.019). In patients with inoperable oropharyngeal carcinoma treated after December 1993, complete remission was achieved in 32/48 (67%, 95% CI: 52%-80%). DFS at the median follow-up of 14 months was 60% (95% CI 43-77%) and OS 58% (95% CI 42-74%). CONCLUSION From the results of our study it seems that the concomitant treatment significantly improves CR rate, DFS, and OS in patients with inoperable oropharyngeal carcinoma in comparison with radiotherapy alone.

Abstract
Oral mucositis is a common, dose limiting and potentially serious complication of both radiation and chemotherapy. Both these therapies are non-specific, interfering with the cellular homeostasis of both malignant and normal host cells. An important effect is the loss of the rapidly proliferating epithelial cells in the oral cavity, gut and in the bone marrow. Within the mouth, the loss of these cells leads to mucosal atrophy, necrosis and ulceration. Although post-treatment healing is generally uneventful, severe mucositis can be life threatening, especially if complicated by dehydration or secondary infection. Accurate and reproducible evaluation of oral mucositis is important in order to monitor patient toxicity during therapy, to document the toxicity of conventional therapy and to critically assess the effects of alternative therapies. A number of oral toxicity scoring systems have been described, but direct comparisons have rarely been undertaken and little data exist regarding inter- and intra-user reliability. This paper reviews a number of oral mucositis scoring systems that are commonly used and will also discuss, briefly, the biological basis of its development and management.

Abstract
Porfiromycin (methyl mitomycin C) has been shown in laboratory studies to have increased preferential cytotoxicity to hypoxic cells and therefore may provide enhanced therapeutic efficacy over mitomycin C when used in combination with radiation therapy (RT). The purpose of the two clinical studies reported here is to evaluate the concomitant use of porfiromycin with RT in the management of squamous cell carcinoma of the head and neck. Between October 1989 and July 1992, 21 patients presenting with locally advanced stage III/IV squamous cell carcinoma of the head and neck were entered into a phase I toxicity trial evaluating porfiromycin as an adjunct to RT. Patients were eligible if they had biopsy documented squamous cell carcinoma of the head and neck with a low probability of cure by conventional means. Patients were treated with standard fractionated daily RT to a total median dose of 63 Gy, with porfiromycin administered on days 5 and 47 of the course of RT. Upon completion of this phase I trial, a phase III trial was initiated in November 1992 randomizing patients with squamous cell carcinoma of the head and neck to RT with mitomycin C vs. RT with porfiromycin. There is no radiation only arm in this current trial. To date, 75 patients have been entered on this trial and acute toxicity data are available on 67 patients (34 porfiromycin, 31 mitomycin C) who have completed their entire course of treatment. Median follow-up of the 21 patients enrolled in the phase I porfiromycin trial is 58.5 months. Of the 21 patients, 5 were treated at a dose of 50 mg/M2, 4 at 45 mg/M2, and the final 12 at 40 mg/M2, which appeared to result in acceptable acute hematological and nonhematological toxicities. As of December 1995, 14 of the 21 patients have died with disease and 7 remain alive and free of disease, resulting in a 5-year actuarial survival of 32%. Of the patients enrolled to date in the phase III randomized trial of mitomycin C vs. porfiromycin, there have been no statistically significant differences between the two arms with respect to white blood cell count (WBC), platelet, or hemoglobin nadirs. Acute nonhematological toxicities including mucositis, epidermitis, odynophagia, and nausea have also been comparable. Two patients in this current randomized trial died during treatment, apparently of nondrug-related causes. We conclude that the bioreductive alkylating agent porfiromycin has demonstrated an acceptable toxicity profile to date. Final analysis of the phase I trial, which revealed a 5-year no evidence of disease survival rate of 32% in patients with locally advanced disease and a low probability of cure, appears encouraging. We anticipate completion of the current ongoing trial comparing mitomycin C to porfiromycin in the next 2 years. Further investigations, including large-scale multiinstitutional trials employing bioreductive alkylating agents or other hypoxic cell cytotoxins as adjuncts to RT, are warranted.

Abstract
PURPOSE To define the maximum tolerated dose (MTD) by describing the dose-limiting toxicity (DLT) of weekly paclitaxel (PAC) given as a 1-h I.V. infusion in patients with head and neck cancer concomitant to irradiation. METHODS AND MATERIALS Patients with unresectable or incompletely resected head and neck cancer were enrolled into a prospective, dose-escalating Phase I study. Toxicity was graded according to the WHO toxicity score. MTD dose was defined when two out of six patients developed DLT. The starting dose of PAC was 20 mg/m2 once weekly I.V. over 60 min, with a subsequent dose escalation of 10 mg/m2 in cohorts of three new patients. Radiation therapy was administered in three field technique over 6-7 weeks in 2.0 Gy/daily fractions for 5 consecutive days/week up to total doses of 60-70 Gy. RESULTS From 1994-1996, 18 patients completing three dose levels were included into the study. Altogether, 101 courses of chemotherapy were evaluable for toxicity. On the second dose level (30 mg/m2) one of three patients experienced DLT with Grade IV mucositis. On the next dose level with 40 mg/m2 PAC weekly one patient experienced DLT being prolonged Grade III mucositis. From the following three patients required, two patients showed no DLT. The third patient showed mucositis of WHO Grade 4 and died from hemorrhage caused by a rupture of the a pharyngeal wall. Dose level 2 (30 mg/m2) was repeated and one of the three newly treated patients again suffered from mucositis WHO Grade 4. CONCLUSION When PAC is given weekly as a 1-h infusion concomitant to radiotherapy, MTD is 30 mg/m2 with mucositis being DLT; hematological and further nonhematological toxicity is mild.

Abstract
Bleomycin (BLM) is a natural antibiotic, toxic to dividing cells (G2/M-phase), also proven effective in squamous cell carcinomas (SCC). We have clinically shown that a short-range beta-emitting radionuclide combined to bleomycin (In-111-BLMC) is a tumor-targeting agent in SCCs. With higher radionuclide activities it may be possible to develop a more effective agent, to be tested in animal studies. Using a 96-well clonogenic assay we investigated three SCC cell lines, grown in our own laboratory. IC20, IC50 and IC90 values for BLM were determined. The UT-SCC-12A and UT-SCC-12B cells were originated from a primary tumor and a metastasis of the same patient. UT-SCC-12A cells were also inoculated subcutaneously into nude mice and the tumor growth was analysed. The IC50 value for UT-SCC-19A cell line was 4.0 +/- 1.3 nM. UT-SCC-12A and UT-SCC-12B were both more resistant to BLM; IC50 values were 14.2 +/- 2.8 nM and 13.0 +/- 1.1 nM, respectively. Within 35 days the weight of nude mice increased 2.8 +/- 0.6g. At 25 and 35 days after tumor inoculations the tumor volumes were 111 +/- 51 mm3 and 874 +/- 577 mm3, respectively. The calculated doubling time was 3.86 +/- 0.76 days. SCC cell lines demonstrate different sensitivity to BLM. Our SCC tumor xenograft model showed a rapid growth proper for radiochemotherapeutic studies using In-111-BLMC. The uptake of In-111-BLMC in vivo has been directly proportional to proliferation activity, and the tumors with high binding capacity could be predicted from animal model dose calculations.
