Rapid palliation of symptoms with platinum-based chemotherapy plus cetuximab in recurrent oral cancer: a case report.
BACKGROUND
Symptom control is an important consideration in the choice of treatment for patients with recurrent and/or metastatic squamous cell carcinoma of the head and neck (SCCHN). Patients who demonstrate objective tumour responses to platinum-based chemotherapy are more likely to have symptom relief than those who do not have such responses. A phase III trial (EXTREME) showed that adding the epidermal growth factor receptor (EGFR)-targeting IgG1 monoclonal antibody cetuximab to first-line platinum-based chemotherapy significantly prolongs progression-free and overall survival and increases response rate compared with platinum-based chemotherapy alone. We report here the case of a 60-year old female with recurrent squamous cell carcinoma of the gum who had rapid palliation of symptoms and reduction of facial disease mass following treatment with a combination of carboplatin/5-fluorouracil (5-FU) and cetuximab.


METHODS
The patient was diagnosed with T4N0 M0 disease of the oral cavity in November 2006 and underwent surgery, with R0 resection, followed by adjuvant radiotherapy and concomitant cisplatin chemotherapy. Around 3 months later, the disease recurred and the patient had severe pain (9/10 on a visual pain scale), marked facial oedema and a palpable facial mass of 89 mm. The patient received 4 21-day cycles of carboplatin (AUC 5), 5-FU (1,000 mg/m2/day for 4 days) and cetuximab (400 mg/m2 initial dose followed by subsequently weekly doses of 250 mg/m2), with continuation of cetuximab monotherapy at the end of this time, and pain relief with topical fentanyl and oral morphine. After 7 days of treatment, pain had reduced to 2/10, with discontinuation of morphine after 4 days, and the facial mass had reduced to 70 mm. After 2 cycles of treatment, the facial mass had decreased to 40 mm. After 3 cycles of treatment, pain and facial oedema had resolved completely and a cervical computed tomography scan showed a marked reduction in tumour mass. Cetuximab monotherapy was continued uninterrupted for 7 months.


CONCLUSIONS
This case illustrates the rapid reduction of tumour mass and disease-associated pain and oedema that can be achieved with a combination of platinum-based chemotherapy and cetuximab in recurrent and/or metastatic SCCHN.
