[Comparison of long-term carcinologic results between radical and conservative cervical surgery]

The aim of this research was to compare isolated ganglionic development in patients treated surgically for cancer of the larynx. This research included the cases of 232 patients operated on for laryngeal cancer and who underwent either total laryngectomy with or without conservation of the cricoid, or supra-glottal laryngectomy, or sub-glottal pharyngectomy. For the treatment of the ganglionic areas, there are six possibilities: --cobalt used in isolation; --uni- or bi-lateral cellulo-adenectomy; --uni- or bi-lateral curettage (a month apart); --curettage on one side, cellulo-adenectomy on the other. The results obtained were particularly significant as far as the N0 and regrouped N1 were concerned. The rate of ganglionic recurrence was 25 p. 100 for the N0 treated with cobalt and 6,5 p. 100 when surgery was carried out (cellulo-adenectomy or curettage). Also, curettage seems in N + cases to give better results : 26 p. 100 recurrence in cases of cellulo-adenectomy for N0-N1 and 4 p. 100 only in cases of curettage. These results appear to justify on the spot histological examination followed by curettage in N + cases.
