Combined modality treatment with chemotherapy and radiation produces tumor
regression in most patients with small-cell lung cancer, but the impact on
survival has been small, and less than 20% of patients with limited disease
survive 2 years. Survival time is extremely short after failure to respond
or relapse after treatment. Local control remains a problem, with one third
of patients having recurrence only at the primary site. In an attempt to
prolong survival and perhaps achieve cure, we undertook surgical resection
in 28 patients with limited small- cell lung cancer who did not have
complete remission with standard treatment or who had only local recurrence
after treatment. There were 28 patients, 22 male and six female, median age
61 years (range 41 to 76). All patients had been treated with chemotherapy
and 13 had received preoperative radiotherapy to the primary site and
mediastinum. Eight patients underwent an operation for relapse after
complete remission. Five patients had had no response to treatment, three
had had a slight response followed by progression during chemotherapy, and
12 had achieved partial response but had greater than 3 cm residual masses.
Twelve patients required pneumonectomy, 15 lobectomy, one patient had
unresectable disease, and two had bulky residual masses after the
operation. Three others had microscopic residual disease. Pathologic
examination showed only small-cell lung cancer in 18 patients, mixed
small-cell and non-small-cell in four, and only non- small-cell lung cancer
in six. There were only four patients with stage I disease, 10 with stage
II, and 14 with stage III. The median survival from the date of diagnosis
for the entire group is 105 weeks and from the date of operation, 74 weeks.
The projected 5-year survival rate is 23%. The two patients with residual
masses died with local progression, and distant metastatic disease
developed in 17 others. One patient died at 6 years without recurrent
disease. Eight patients are alive 2 to 5 years after diagnosis. Seven of
these patients required only a lobectomy, four had stage I disease, two had
stage II, and two had stage III disease. Five had pure small-cell lung
cancer and three had mixed small-cell and non-small-cell tumors. All of the
patients with pathologic stage I disease remain alive compared with one of
10 with stage II disease and two of 14 with stage III. In summary, relapse
or failure to respond to chemotherapy may be due to non-small-cell lung
cancer or a mixed tumor.(ABSTRACT TRUNCATED AT 400 WORDS)
