Wenig BL, Werner JA, Castro DJ, et al. The Role of Intratumoral Therapy With Cisplatin/Epinephrine Injectable Gel in the Management of Advanced Squamous Cell Carcinoma of the Head and Neck. Arch Otolaryngol Head Neck Surg. 2002;128(8):880–885. doi:https://doi.org/10.1001/archotol.128.8.880
To determine the safety and efficacy of targeted antitumor therapy with cisplatin/epinephrine injectable gel in patients with advanced squamous cell carcinoma of the head and neck.
Two prospective, double-blind, placebo-controlled phase III trials of identical design. Crossover from blinded to open-label phase was permitted for patients with disease progression.
Tertiary referral centers in North America and Europe.
One hundred seventy-nine intensively pretreated patients with recurrent or refractory squamous cell carcinoma of the head and neck.
Cisplatin/epinephrine injectable or placebo gel was administered by direct intratumoral injection; up to 6 weekly treatments. Dose was 0.25 mL of active or placebo gel per cubic centimeter of tumor up to 10 mL total. Patient benefit after local tumor control of the most symptomatic tumor was assessed by patients and physicians using the Treatment Goals Questionnaire.
Main Outcome Measures
Local tumor response and patient benefit attributable to improvements in tumor-related symptoms.
Combined results for the 178 patients with evaluable data in the 2 trials confirmed objective tumor responses in 35 (29%) of 119 patients, including 23 (19%) complete responses achieved with cisplatin/epinephrine gel, vs 1 (2%) of 59 for placebo (P<.001). Tumor response and patient benefit were significantly correlated (P = .006): 47% (17/36) of patients with target tumor responses achieved a rigorously defined benefit based on a prospectively selected treatment goal vs 15% (22/142) of nonresponders.
Cisplatin/epinephrine injectable gel reduces tumor burden, ameliorates tumor symptoms, and provides a new therapeutic option for treating patients with squamous cell carcinoma of the head and neck.
