    Abstract:
    From May 1980 to May 1984, preoperative chemotherapy (mitomycin C and 5-fluorouracil) was added to radiation therapy in patients with potentially operable squamous cell carcinoma of the esophagus. Of 129 patients observed, 122 were followed up until death or to the present. Only 33 were able to complete preoperative chemotherapy and radiation and undergo resection. There were 28 men and five women, their ages ranging from 42 to 81 years (average 60 years). There were 22 black and 11 white patients. The location of the tumor was in the middle third in 70% of the patients. Among the 33 patients, the clinical TNM classification was as follows: T1 N0 M0, three patients; T2 N0 M0, 27 patients; T2 N1 M0, two patients; and T3 N0 M0, one patient. The length of the lesions when measurable in the absence of complete obstruction varied from 3 to 17 cm (average 7 cm). The operative mortality rate in this group was 12% (4/33). There was no viable residual tumor in the surgical specimen of the esophagus in 33% (11/33) of those patients completing triple therapy. However, in two of the 11 patients, left gastric nodes contained tumor and in one there was a minute esophageal perforation. The 2-year survival rate was 33% (11/33), and the 5-year survival rate was 15.4% (5/33). Among the 11 patients having 2-year survival, the surgical specimen was normal in six and abnormal in five. Of the five patients having 5-year survival, the surgical specimen was normal in three and abnormal in two. The absence of tumor in the surgical specimen did not appear to confer any better chance for long-term survival. Data were compared to our 1967-1975 series of 75 patients receiving only preoperative radiation and resection. There was no significant difference in survival rates at 2 years (20% [1975] versus 33% [1984], p = 0.2118) or at 5 years (10% [1975] versus 15.4% [1984], p = 0.5796). The addition of preoperative chemotherapy as an adjunct did not result in a statistically significant increase in 2-year or 5-year survival rates.
