lüll Intra-oral cancer at the Massachusetts General Hospital Squamous cell carcinoma of the floor of the mouth Ildstad ST; Bigelow ME; Remensnyder JPAnn Surg 1983[Jan]; 197 (1): 34-41A retrospective review of 163 consecutive patients with biopsy-proven, invasive squamous cell carcinoma of the floor of the mouth who underwent inpatient treatment at the Massachusetts General Hospital during the 15-year period from January 1962 through December 1976 is presented. The stage at first presentation, clinical features of the disease, incidence of second primary tumors, analysis of therapeutic modalities, and survival statistics are compared with reports from other large centers. Floor of mouth tumors comprised 28%, (163/592) of oral squamous cell carcinomas seen at the Massachusetts General Hospital during that time period. Seventy-one per cent of floor of mouth tumors were in men and 29% in women; women tended to present earlier in the course of their disease. Thirty-seven patients (23%) developed a secondary primary malignancy, and four of these 37 patients developed two second primaries. Distant metastatic disease appeared in 6% of patients with Stage I, II, or III disease and 26% of patients with Stage IV disease. Radiation therapy alone and surgery alone resulted in equivalent long-term survival rates for early stage disease. In more advanced stages (III and IV), a combined approach utilizing surgery and radiation therapy obtained superior results for short-term survival than either modality alone. The importance of early diagnosis and treatment and suggestions for development of cooperative protocols in an attempt to improve salvage of patients with this disease is discussed.|Adult[MESH]|Aged[MESH]|Carcinoma, Squamous Cell/mortality/*therapy[MESH]|Female[MESH]|Humans[MESH]|Male[MESH]|Middle Aged[MESH]|Mouth Neoplasms/mortality/*therapy[MESH]|Neoplasm Metastasis[MESH]|Neoplasms, Multiple Primary/therapy[MESH]|Postoperative Complications[MESH]|Radiotherapy/adverse effects[MESH]|Retrospective Studies[MESH] |
