A prospective study of the efficacy and toxicity profile of patients with squamous cell carcinoma of the head and neck (HNSCC) without curative treatment options treated consistently with hypofractionated radiotherapy schedule.
Between 1995 and 2006, 158 patients with HNSCC, unsuitable for curative treatment, were treated with a hypofractionated scheme of radiotherapy consisting of 16 fractions of 3.125 Gy. Endpoints of the study were response rates, loco-regional control, disease-free survival, overall survival, acute and late toxicity, and quality of life (QoL).
Seventy four percent of patients were male, 31% had oropharyngeal cancer and 81% stage IV disease. With 45% complete response and 28% partial response an overall response rate of 73% was achieved, 6% had stable disease, and 21% progressed during or directly after completion of treatment. Median survival time was 17 months and 62 patients (40%) survived > or =1 year after RT. The actuarial rates of loco-regional control, disease-free survival and overall survival were 62%, 32% and 40% at 1-year, respectively and 32%, 14% and 17% at 3-years, respectively. Acute grade > or =3 skin and mucosal toxicities were observed in 45% and 65% of patients, respectively. Severe late toxicity was reported in 4.5% of patients. Of patients surviving > or =1 year after RT, retrospective chart review showed that 50% gained weight, pain improved in 77%, performance status in 47% and only 29% of them was still feeding-tube dependent.
Our hypofractionated radiotherapy scheme is an effective, well-tolerated and safe palliative schedule in HNSCC who are unsuitable for curative treatment options. Using 3.125 Gy per fraction (Christie scheme), excellent palliation was achieved resulting in acceptable response rates, excellent symptom control, acceptable toxicity profile, and good QoL of patients surviving > or =1 year after completion of treatment.
对头颈部鳞状细胞癌(HNSCC)患者进行前瞻性研究,这些患者没有根治性治疗选择,采用超分割放疗方案持续治疗。
1995年至2006年间,158例不适合根治性治疗的HNSCC患者接受了超分割放疗方案,该方案由16次每次3.125 Gy的照射组成。研究终点为缓解率、局部区域控制、无病生存期、总生存期、急性和晚期毒性以及生活质量(QoL)。
74%的患者为男性,31%患有口咽癌,81%为IV期疾病。45%的患者完全缓解,28%部分缓解,总缓解率达到73%,6%病情稳定,21%在治疗期间或治疗结束后直接进展。中位生存时间为17个月,62例患者(40%)在放疗后存活≥1年。1年时局部区域控制、无病生存期和总生存期的精算率分别为62%、32%和40%,3年时分别为32%、14%和17%。分别有45%和65%的患者观察到急性3级及以上皮肤和黏膜毒性。4.5%的患者报告有严重晚期毒性。在放疗后存活≥1年的患者中,回顾性病历审查显示50%体重增加,77%疼痛改善,47%功能状态改善,其中只有29%仍依赖鼻饲管。
我们的超分割放疗方案对于不适合根治性治疗选择的HNSCC患者是一种有效、耐受性良好且安全的姑息性方案。采用每次3.125 Gy(克里斯蒂方案),可实现良好的姑息治疗效果,从而获得可接受的缓解率、出色的症状控制、可接受的毒性反应以及治疗结束后存活≥1年患者良好的生活质量。
