A proportion of advanced stage head and neck cancer patients are incurable and have a limited life expectancy of 100 days or less. The study aimed to offer a short course of palliative radiotherapy (PRT) and evaluate the symptom relief, disease response and duration of survival.
Between 1995 and 2001, 505 patients of stage IV squamous cell carcinoma received uniform dose of 20 Gy in 5 fractions over 1 week along with symptom relief drugs. Incurable status and decision for palliation was made conjointly. Distressing symptoms were assessed before PRT. Patients showing more than 50% objective regression (PR) at tumor and nodal sites received further RT (FRT) up to 70 Gy.
The overall PR rate was 37% (189 patients), but 153 (30%) completed FRT, and rest 352 were followed up after PRT only. None of the patients died due to radiation toxicity, and the radiation morbidities were confined to dry desquamation and patchy mucositis, which healed over 1 month. Symptom relief for pain, dysphagia, hoarseness, cough and otalgia was obtained in 47%-59% of the patients following PRT. The overall survival ranged from 34 days to 2065 days and median survival to PRT and FRT were 200 days and 400 days, respectively. Only 10% were disease-free after FRT.
Unfavourable advanced stage head and neck cancer can be identified for a suitable short course of palliative radiotherapy which will achieve growth restraint and symptom relief in sizeable proportions for an approximate period of 7 months.
一部分晚期头颈癌患者无法治愈,预期寿命在100天或更短。本研究旨在提供一个短疗程姑息性放疗(PRT),并评估症状缓解情况、疾病反应及生存时间。
1995年至2001年间,505例IV期鳞状细胞癌患者在1周内分5次接受20 Gy的均匀剂量放疗,同时给予缓解症状的药物。共同确定无法治愈的状态及姑息治疗的决定。在PRT前评估痛苦症状。在肿瘤和淋巴结部位显示出超过50%客观缓解(PR)的患者接受进一步放疗(FRT),剂量达70 Gy。
总体PR率为37%(189例患者),但153例(30%)完成了FRT,其余352例仅在PRT后接受随访。没有患者因放疗毒性死亡,放疗并发症仅限于干性脱皮和斑片状粘膜炎,1个月内愈合。PRT后47%-59%的患者疼痛、吞咽困难、声音嘶哑、咳嗽和耳痛等症状得到缓解。总生存期为34天至2065天,PRT和FRT的中位生存期分别为200天和400天。FRT后仅10%的患者无疾病。
对于预后不良的晚期头颈癌,可确定其适合短疗程姑息性放疗,这将在约7个月的时间内使相当比例的患者实现肿瘤生长抑制和症状缓解。
