Title: Rapid hyperfractionated radiotherapy. Clinical results in 178 advanced squamous cell carcinomas of the head and neck

Abstract

The authors present a series of 178 patients with Stage III or IV squamous cell carcinoma of the head and neck treated by rapid irradiation using multiple and small fractions per day. An initial group of 91 patients (G1) received a total dose of 72 Gy in 80 sessions and 10 days, according to the following split course schedule: J1 to J5, 36 Gy in 40 sessions, eight daily fractions of .9 Gy separated by 2 hours; J6 to J20, rest period; J21 to J25, same as in J1 except that the spinal cord was shielded. This protocol was altered for the following 87 patients (G2) by lessening the total dose to 60 to 66 Gy and the number of fractions to 60. The rest period was lengthened to 4 weeks. All patients but five completed the whole program and the minimal follow-up period was 24 months. At the end of irradiation, 121 patients achieved a total remission, but local recurrences occurred in 56%. Moreover, acute intolerance was considered as severe in 34% of G1 patients, and included extensive mucosal necrosis and bleeding. Although this rate was significantly reduced in G2 patients, late complications were observed in 20 of themore » 25 survivors, and included trismus, cervical sclerosis, and recurrent laryngeal edema. The crude survival rate is 13% at 2 years. Although this study was not randomized, this particular type of accelerated and hyperfractionated combination of irradiation did not really improve the clinical results in advanced carcinoma of the head and neck. Other schedules and probably other tumors, less extended, should be tested.« less

  • From January, 1976 to January, 1980, 141 patients (135 males and 6 females) with Stage III and IV squamous cell carcinoma of the head and neck received a split course of hyperfractionated radiotherapy (HFR). In the first group, involving 91 patients, the therapeutic schedule was as follows: first and fourth week, 7.2 Gy per day in 8 sessions of .9 Gy from Monday to Friday, the second and third week no irradiation was given. Thus, patients were given 72 Gy total dose, fractionated into 80 sessions. Mucosal necrosis and severe hemorrhage were responsible for the death of 26 patients (28%).more » Therefore the therapeutic protocol was altered for the 50 patients of the second group: during the first and sixth week 6.6 Gy per day in 6 sessions of 1.1 Gy from Monday to Friday. The total dose was thus reduced to 66 Gy fractionated into 60 sessions, resulting in the decrease of toxicity. Regardless of the therapeutic protocol and site of primary, 114 patients (80%) achieved a complete remission and 8 showed a partial remission (>50%), whereas no change was seen for the 19 remainders. Local recurrence appeared in 60 patients (48%). Acute mucositis and laryngeal edema regularly occurred a week after every course of HFR and were considered severe in 40 patients. In spite of toxicity, the median survival is 14 months and 22 patients are still alive in November 1981: 19 without disease, and 8 of these patients have a survival time of at least 3 years.« less
  • Purpose: To evaluate the feasibility and efficacy of a hyperfractionated accelerated radiotherapy (RT) schedule combined with concomitant chemotherapy (Cx) in patients with locally advanced head-and-neck squamous cell carcinoma. Methods and Materials: Between 2004 and 2007, a total of 90 patients with locoregionally advanced head-and-neck squamous cell carcinoma underwent irradiation according to a hybrid fractionation schedule consisting of 20 fractions of 2 Gy (once daily) followed by 20 fractions of 1.6 Gy (twice daily) to a total dose of 72 Gy. Concomitant Cx (cisplatinum 100 mg/m{sup 2}) was administered at the start of Weeks 1 and 4. Treatment outcome and toxicitymore » were retrospectively compared with a previous patient group (n = 73) treated with the same schedule, but without concomitant Cx, between 2001 and 2004. Results: The locoregional control (LRC) rate was 70% after 2 years. Two-year overall and 2-year disease-free survival rates were 74% and 60%, respectively. In comparison with the RT-only group, an improvement of 15% in both LRC (p = 0.03) and overall survival (p = 0.09) was observed. All patients were treated to full radiation dose according to protocol, although the Cx schedule had to be adjusted in 12 patients. No acute Grade 4 or 5 toxicity was seen, but incidences of Grade 3 acute mucositis (74.5% vs. 50.7%; p = 0.002) and dysphagia (82.2% vs. 47.9%; p < 0.001) were significantly higher in the chemoradiotherapy group compared with patients treated with RT alone. Conclusion: With this chemoradiotherapy regimen, excellent LRC and survival rates were achieved, with acceptable acute toxicity.« less
  • From 1979 to 1980, 52 patients with Stage III-IV squamous cell carcinoma of the head and neck were included in a prospective randomized study on hyperfractionated radiotherapy with or without misonidazole. The radiotherapeutic schedule consisted of two weeks of treatment split by a rest-period of one month, 6 x 1.1 Gy fractions per day for 5 consecutive days. Total dose of misonidazole was 12 g/m2 administered daily in 1.2 g/m2 fractions. The overall tolerance of misonidazole was good, with a neuropathy rate of 5.7%. Local control, recurrence and 3 year survival rates did not statistically differ between the two groups.more » The randomized trials published at the present time, including or own, suggest that misonidazole has no beneficial effect with classical, concentrated or multiple fractions per day radiotherapy.« less
  • Purpose: To report the mature data of a prospective Phase II trial designed to evaluate the efficacy of an epidermal growth factor receptor inhibitor cetuximab (CTX) added to the concurrent therapy of weekly paclitaxel/carboplatin (PC) and daily radiation therapy (RT). Methods and Materials: From 2005 to 2009, a total of 43 patients were enrolled in the study. The median follow-up was 31 months (range, 9-59 months). All patients had Stage III/IV disease at presentation, and 67% had oropharyngeal primaries. The weekly IV dose schedules were CTX 250 mg/m{sup 2} (400 mg/m{sup 2} IV loading dose 1 week before RT), paclitaxelmore » 40 mg/m{sup 2}, and carboplatin AUC 2. RT was given at 1.8 Gy per day to 70.2 Gy. Intensity-modulated RTwas used in 70% of cases. Results: All patients completed the planned RT dose, 74% without any treatment breaks. The planned CTX and PC cycles were completed in 70% (91% with at least seven of planned nine cycles) and 56% (93% with at least seven of planned eight cycles) of patients, respectively. Toxicity included Grade 3 mucositis (79%), rash (9%), leucopenia (19%), neutropenia (19%), and RT dermatitis (16%). The complete response (CR) rate at the completion of therapy was 84%. The estimated 3-year local regional control rate was 72%. Six patients with an initial CR subsequently experienced a local recurrence, 10 patients experienced distant progression. The median overall survival and disease-free survivals have not been reached. The 3-year actuarial overall survival and disease-free survival were 59% and 58%, respectively. Conclusions: The addition of CTX to weekly PC and daily RT was well tolerated and resulted in encouraging local control and survival rates.« less
  • Purpose: To evaluate the radiobiological outcome of Intensity Modulated Radiotherapy Treatment (IMRT) for locally advanced head and neck squamous cell carcinomas using HART (Histogram Analysis in Radiation Therapy; J Appl Clin Med Phys 11(1): 137–157, 2010) program and compare with the clinical outcomes. Methods: We have treated 20 patients of stage III and IV HNSCC Oropharynx and hypopharynx with accelerated IMRT technique and concurrent chemotherapy. Delineation of tumor and normal tissues were done using Danish Head and Neck Cancer Group (DAHANCA) contouring guidelines and radiotherapy was delivered to a dose of 70Gy in 35 fractions to the primary and involvedmore » lymph nodes, 63Gy to intermediate risk areas and 56 Gy to lower risk areas, Monday to Saturday, 6 Days/week using 6 MV Photons with an expected overall treatment time of 6 weeks. The TCP and NTCP's were calculated from the dose-volume histogram (DVH) statistics using the Poisson Statistics (PS) and JT Lyman models respectively and the Resultwas correlated with clinical outcomes of the patients with mean follow up of 24 months. Results: Using HART program, the TCP (0.89± 0.01) of primary tumor and the NTCP for parotids (0.20±0.12), spinal cord (0.05±0.01), esophagus (0.30±0.2), mandible (0.35±0.21), Oral cavity (0.37±0.18), Larynx (0.30±0.15) were estimated and correlated with clinical outcome of the patients. Conclusion: Accelerated IMRT with Chemotherapy is a clinical feasible option in the treatment of locally advanced HNSCC with encouraging initial tumour response and acceptable acute toxicities. The correlation between the clinical outcomes and radiobiological model estimated parameters using HART programs are found to be satisfactory.« less
