In the previously published series of patients with generalized head and neck epidermoid carcinoma, a high dose combination of methotrexate (MTX) (0.4 mg/kg biw. i.v.) and bleomycin (BLM) (30 mg biw. iv) produced an objective remission rate of 60% with a median duration of 9 weeks. The disappointingly short duration of the remissions was tentatively related to the short period of treatment, which was limited to 5 weeks in order to keep the cumulative dosage of BLM below 300 mg. In the present study, covering 26 patients, a lower weekly dose was adopted (BLM 15 mg, MTX 0.6 mg/kg). 13 partial remissions were obtained with a median duration of 26 weeks; in 7 cases there was no evolution, in 6 cases progression of the tumor was registered, and there was one death from hematological toxicity. The major toxicity was leuko- and thrombopenia with one toxic death. Digestive and cutaneous side effects and fever were minor. There were 2 cases of major pulmonary toxicity, one of which was lethal. In conclusion, a combination of MTX and BLM at a relatively low dosage is active in disseminated head and neck carcinoma and appears to be compatible with longer maintenance of palliation in comparison with results obtained at a high dose level.
在先前发表的一系列广泛性头颈部表皮样癌患者中,甲氨蝶呤(MTX)(0.4mg/kg,静脉注射,每周两次)和博来霉素(BLM)(30mg,静脉注射,每周两次)的高剂量联合方案产生了60%的客观缓解率,缓解期中位数为9周。缓解期令人失望地短暂,这初步与治疗周期短有关,为了使BLM的累积剂量低于300mg,治疗周期限制在5周。在本研究中,纳入了26例患者,采用了较低的每周剂量(BLM 15mg,MTX 0.6mg/kg)。获得了13例部分缓解,缓解期中位数为26周;7例病情无进展,6例记录到肿瘤进展,1例死于血液学毒性。主要毒性是白细胞减少和血小板减少,有1例因毒性死亡。消化和皮肤副作用以及发热较轻。有2例严重肺部毒性,其中1例致死。总之,与高剂量水平的结果相比,相对低剂量的MTX和BLM联合方案对播散性头颈部癌有活性,并且似乎与更长时间的姑息维持治疗相容。
