Abstract
Background: Combination therapy consisting of a platinum agent, 5-fluorouracil and cetuximab (EXTREME regimen) is recommended for recurrent or metastatic squamous cell carcinoma of the head and neck (R/M-SCCHN). However, it is advisable to use platinum-free regimens as first-line therapy in patients resistant to platinum agents. There has been no report comparing EXTREME regimen outcomes between platinum-resistant and platinum-sensitive patients.
Objectives: We conducted this study to examine the outcomes of the EXTREME regimen as first-line therapy in patients with R/M-SCCHN and a history of platinum agent use and assess whether the EXTREME regimen outcomes differ between platinum-resistant and platinum-sensitive patients.
Materials and methods: The study included 32 patients with R/M-SCCHN who received the EXTREME regimen as first-line therapy. Patients with recurrence or metastasis within 6 months after cisplatin administration were considered platinum-resistant and those with no recurrence or metastasis within 6 months were considered platinum-sensitive.
Results: 17 patients were platinum-resistant and 15 patients were platinum-sensitive. The median survival durations were 10.6 and 19.9 months in the platinum-resistant and platinum-sensitive patients, respectively, and the prognosis was significantly better in the platinum-sensitive patients (p = .02).
Conclusions: Our findings suggest that the EXTREME regimen is useful as first-line therapy for R/M-SCCHN in platinum-sensitive patients.

背景:由铂剂、5-氟尿嘧啶和西妥昔单抗(EXTREME方案)组成的联合治疗被推崇用于治疗头颈部复发性或转移性鳞状细胞癌(R / M-SCCHN)。然而, 建议对耐铂剂的患者使用无铂方案作为一线治疗。还没有关于比较铂耐药和铂敏感患者的EXTREME方案结果的报道。
目的:检查作为R / M-SCCHN患者的一线治疗的EXTREME方案的结果和使用铂剂的历史, 并评估EXTREME方案结果在铂耐药患者和铂敏感患者之间是否不同。
材料和方法:该研究纳入了32名R / M-SCCHN患者, 他们接受了作为一线治疗的EXTREME方案。顺铂给药后6个月内复发或转移的患者被认为是铂耐药, 6个月内没有复发或转移的患者被认为是铂敏感。
结果:17名患者铂耐药, 15名患者铂敏感。铂耐药和铂敏感患者的中位生存期分别为10.6和19.9个月, 铂敏感患者的预后明显更好(p = .02)。
结论:我们的研究结果表明, EXTREME方案可用作铂敏感患者R / M-SCCHN的一线治疗。
