Patients presenting with Stage III-IV squamous carcinoma of the head and neck often relapse following aggressive surgery and/or radiotherapy. In an attempt to increase survival in this high risk group of patients, HD-MTX, 3 gm./m2/dose, given weekly, was administered to 21 inoperable patients with Stage III/IV squamous carcinoma of head and neck prior to, and for 1 month after, definitive surgery and/or radiotherapy. Six of 11 patients (55%) who showed a significant response (greater than 50% reduction in tumor volume) to HD-MTX are alive and free of tumor greater than 38 months following treatment (p = 0.6) (Fisher Exact Test). Responder median survival is greater than 38 months while non-responder median survival is 15 months (p = .02) (Log Rank Test). For the entire treatment group, at a mean duration of 44.2 months following initiation of therapy, 7 patients (33%) remain alive and free of tumor. Patients responding to induction MTX-LCV more often become eligible for combined modality approach than did the non-responder group. This "downstaging" of the tumor prior to aggressive surgery or radiotherapy may be responsible for the increased survival rate seen in those patients who responded to MTX-LCV.
患有III-IV期头颈部鳞状癌的患者在接受积极的手术和/或放疗后常出现复发。为了提高这一高危患者群体的生存率,对21例无法手术的III/IV期头颈部鳞状癌患者在确定性手术和/或放疗前及放疗后1个月每周给予3克/平方米剂量的大剂量甲氨蝶呤(HD-MTX)。11例对HD-MTX有显著反应(肿瘤体积缩小超过50%)的患者中有6例(55%)在治疗后38个月以上仍存活且无肿瘤(p = 0.6)(Fisher精确检验)。有反应者的中位生存期大于38个月,而无反应者的中位生存期为15个月(p = 0.02)(对数秩检验)。对于整个治疗组,在开始治疗后的平均44.2个月时,7例(33%)患者仍存活且无肿瘤。与无反应组相比,对诱导性甲氨蝶呤-亚叶酸钙(MTX-LCV)有反应的患者更常符合联合治疗方法的条件。在积极的手术或放疗前肿瘤的这种“降期”可能是导致那些对MTX-LCV有反应的患者生存率提高的原因。
