Article of the week: Pilot study of EGFR-targeted therapies in men with penile SCC shows promising initial results
Every week the Editor-in-Chief selects the Article of the Week from the current issue of BJUI. The abstract is reproduced below and you can click on the button to read the full article, which is freely available to all readers for at least 30 days from the time of this post.
In addition to the article itself, there is an accompanying editorial written by a prominent member of the urological community. This blog is intended to provoke comment and discussion and we invite you to use the comment tools at the bottom of each post to join the conversation.
Finally, the third post under the Article of the Week heading on the homepage will consist of additional material or media. This week we feature a video from Dr. Pagliaro discussing his paper.
If you only have time to read one article this week, it should be this one.

OBJECTIVE
• To evaluate the safety and efficacy of epidermal growth factor receptor (EGFR)-targeted therapy in patients with advanced penile or scrotal cancer.
PATIENTS AND METHODS
• We retrospectively reviewed the charts of patients with penile or scrotal squamous cell carcinoma who had visited our tertiary cancer centre between 2002 and 2009, including their subsequent treatment and follow-up.
• We collected details of EGFR-targeted therapy and clinical outcomes. Treatment-associated time-to-disease-progression (TTP), overall survival (OS), responses to therapy and toxicity were evaluate
RESULTS
• A total of 24 patients had received EGFR-targeted therapies, including cetuximab, erlotinib and gefitinib. The most common treatment given (to 67% of patients) was cetuximab combined with one or more cytotoxic drugs.
• The most common adverse effect was skin rash (71%). The median (range) TTP and OS were 11.3 (1–40) and 29.6 (2–205) weeks, respectively. The OS time for patients with visceral or bone metastases was significantly shorter than it was for those without (24.7 vs 49.9 weeks, P = 0.013).
• Among 17 patients treated with cetuximab alone or in combination with cisplatin, there were four partial responses (23.5%) including two patients with apparently chemotherapy-resistant tumours.
CONCLUSIONS
• Our results suggest that cetuximab has antitumour activity in metastatic penile cancer, and may enhance the effect of cisplatin-based chemotherapy.
• Prospective studies of EGFR-targeted therapies in men with these tumours are warranted
