A randomized study comparing cisplatin alone or combined in the palliative treatment of carcinoma of the head and neck. Analysis of a series of 209 patients

Two hundred and nine patients, with locoregional or metastatic recurrences of head and neck epidermoid carcinoma, were randomized to receive a palliative chemotherapy. The chemotherapy regimens were delivered every 3 weeks, and consisted in (1) cisplatin, 80 mg/m2 given alone (CDDP regimen), or (2) in combination with vincristine, 1 mg, methotrexate 10 mg/m2 d 1, 2, 3, and bleomycin 10 mg/m2, d 1, 2 and 3 (1040 regimen). Short-term results were better for patients treated by the 1040 regimen, with a 30% response rate (including 4 complete responses) vs 15% with the CDDP regimen (P = 0.01). A superiority of combination chemotherapy was found for all tumoral sites, but was particularly significant for pulmonary and cutaneous metastases, in previously un irradiated areas (P = 0.001). Tolerance was significantly better with the CDDP regimen (P = 0.001); severe side effects, affecting mainly general status, digestive tract and bone marrow were encountered in 5% of the patients in the CDDP group, vs 21% in the 1040 group, with one death related to pancytopenia. The median duration of remissions was not statistically different in the 2 groups, as well as the 2 years overall survival. Among responders, the survival was slightly better in those treated with CDDP alone; moreover, the quality of long term results was found highly correlated with a good initial general status, and with low levels of side effects. Those results confirm recent data of the literature, and lead to the following conclusions: (1) combination chemotherapy with CDDP give a better response rate than CDDP alone, (2) response rate doesn't influence overall duration of survival, (3) tolerance to treatment is crucial to preserve quality of life, and thus, (4) palliative chemotherapy in head and neck cancer should be efficient but also as short of intensity as possible.
