We sought to improve outcomes for patients with high-risk head and neck squamous cell cancer (HNSCC) after surgical resection by testing the feasibility and safety of early postoperative chemotherapy followed by concurrent chemoradiotherapy.
Eligible patients had resected, stages III to IV HNSCC with positive margins, extracapsular nodal extension, or multiple positive nodes. Paclitaxel (80 mg/m(2)) was given once weekly during postoperative weeks 2, 3, and 4 and was given before radiation therapy (RT). Paclitaxel (30 mg/m(2)) and cisplatin (20 mg/m(2)) were given once weekly during the last 3 weeks of RT (60 Gy over 6 weeks, beginning 4 to 5 weeks after surgery). The primary end points were treatment safety and tolerability compared with concurrent cisplatin (100 mg/m(2) every 3 weeks) and RT, as tested in Radiation Therapy Oncology Group trial RTOG 9501.
The median follow-up time for the 70 patients enrolled was 3.3 years (range, 0.6 to 4.4 years) for surviving patients. Tolerability of all treatment components was comparable to that of RTOG 9501 treatment, which is the current standard of care (compliance rate, 75%; 95% CI, 63% to 85%). One patient died, and seven patients experienced grade 4 nonhematologic toxicities. Rates of locoregional control, disease-free survival, and overall survival exceeded those of RTOG 9501 after adjustment for important prognostic variables (ie, positive margins, extracapsular extension, primary site, and performance status).
Chemotherapy soon after surgery followed by concurrent chemoradiotherapy therapy was feasible; tolerance was in line with standard postoperative chemoradiotherapy; and this regimen led to excellent rates of locoregional control and disease-free survival.

    • "More recent studies have been conducted to attempt to improve upon the control rates for high-risk HNSCC achieved in RTOG 9501 and EROTC 22931. RTOG 0024 has examined the use of early post-operative paclitaxel followed by a chemoradiation regimen that included both cisplatin and paclitaxel (90). Of the 70 patients enrolled in this phase II study, seven experienced grade 4 non-hematologic toxicity, one experienced grade 4 late toxicity, and one patient died of myocardial ischemia. "

    ABSTRACT: The oral cavity is the most common site of head and neck squamous cell carcinoma, a disease which results in significant morbidity and mortality worldwide. Though the primary modality of treatment for patients with oral cavity cancer remains surgical resection, many patients present with advanced disease and are thus treated using a multi-disciplinary approach. Patients with extracapsular spread of lymphatic metastasis and surgical margins that remain positive have been found to be at high risk for local-regional recurrence and death from disease, and are most often recommended to receive both post-operative radiation as well as systemic chemotherapy. The basis for this approach, as well as scientific developments that underly future trials of novels treatments for patients with high-risk oral cavity cancer are reviewed.

    • "The previous reports of locally advanced head and neck cancer patients who underwent surgery followed by RT concurrent with or without chemotherapy had 2-year estimated OS, DFS, and LRPFS of 63%-83%, 58%-87%, and 65%-91%, respectively [3-5,14-19]. The 2-year actuarial OS, DFS, LRPFS, and DMF rates in the current study are 94%, 84%, 92%, and 94%, respectively. "

    ABSTRACT: The aim of this study was to assess the treatment results and toxicity profiles of helical tomotherapy (HT) for postoperative high-risk oral cavity cancer. From December 6, 2006 through October 9, 2009, 19 postoperative high-risk oral cavity cancer patients were enrolled. All of the patients received HT with (84%) or without (16%) chemotherapy. The median follow-up time was 17 months. The 2-year overall survival, disease-free survival, locoregional control, and distant metastasis-free rates were 94%, 84%, 92%, and 94%, respectively. The package of overall treatment time > 13 wk, the interval between surgery and radiation ≤ 6 wk, and the overall treatment time of radiation ≤ 7 wk was 21%, 84%, and 79%, respectively. The percentage of grade 3 mucositis, dermatitis, and leucopenia was 42%, 5% and 5%, respectively. HT achieved encouraging clinical outcomes for postoperative high-risk oral cavity cancer patients with high compliance. A long-term follow-up study is needed to confirm these preliminary findings.

    ABSTRACT: At the beginning of autumn, 1996, fish with "punched-out" skin lesions and erratic behaviour associated with exposure to toxins produced by Pfiesteria piscicida or Pfiesteria-like dinoflagellate species were seen in the Pocomoke River and adjacent waterways on the eastern shore of the Chesapeake Bay in Maryland, USA. In August, 1997, fish kills associated with Pfiesteria occurred in these same areas. People who had had contact with affected waterways reported symptoms, including memory difficulties, which raises questions about the human-health impact of environmental exposure to Pfiesteria toxins. We assessed 24 people who had been exposed. We collected data on exposure history and symptoms, did a complete medical and laboratory assessment (13 people), and carried out a neuropsychological screening battery. Performance on neuropsychological measures was compared with a matched control group. People with high exposure were significantly more likely than occupationally matched controls to complain of neuropsychological symptoms (including new or increased forgetfulness); headache; and skin lesions or a burning sensation of skin on contact with water. No consistent physical or laboratory abnormalities were found. However, exposed people had significantly reduced scores on the Rey Auditory Verbal Learning and Stroop Color-Word tests (indicative of difficulties with learning and higher cognitive function), and the Grooved Pegboard task. There was a dose-response effect with the lowest scores among people with the highest exposure. By 3-6 months after cessation of exposure, all those assessed had test scores that had returned to within normal ranges. People with environmental exposure to waterways in which Pfiesteria toxins are present are at risk of developing a reversible clinical syndrome characterised by difficulties with learning and higher cognitive functions. Risk of illness is directly related to degree of exposure, with the most prominent symptoms and signs occurring among people with chronic daily exposure to affected waterways.
