Purpose : This is a retrospective study evaluate the response rate, acute toxicity, and
survival rate of a combined chemotherapy and radiation therapy in limited disease small
cell lung cancer.
Materials and Methods : Forty-six patients with limited disease small-cell lung cancer
who underwent combined chemotherapy and radiation therapy between October 1994 and
April 1998 were evaluated. Six cycles of chemotherapy were planned either using a VIP
regimen (etoposide, ifosfamide, and sis-platin) or a EP regimen (etoposide and
sis-platin). Thoracic radiation therapy was planned to deliver 44 §í using 10MV X-ray,
starting concurrently with chemotherapy. Response was evaluated 4 weeks after the
completion of the planned chemotherapy and radiation therapy, and the prophylactic
cranial irradiation was planned only for the patients with complete responses. Acute
toxicity was evaluated using the SWOG toxicity criteria, and the overall survival and
disease-free survival were calculated using the Kaplan-Meier Method.
Results : The median follow-up period was 16 months (range:2 to 41 months).
Complete response was achieved in 30 (65%) patients, of which 22 patients received
prophylactic cranial irradiations. Acute toxicities over grade ¥² were granulocytopenia in
23 (50%), anemia in 17 (37%), thrombocytopenia in nine (20%), alopecia in nine (20%),
nausea/vomiting in five (11%), and peripheral neuropathy in one (2%). Chemotherapy
was delayed in one patient, and the chemotherapy doses were reduced in 58 (24%) out
of the total 246 cycles. No radiation esophagitis over grade ¥² was observed, while
interruption during radiation therapy for a mean of 8.3 days occurred in 21 patients. The
local recurrences were observed in 8 patients and local progressions were in 6 patients,
and the distant metastases in 17 patients. Among these, four patients had both the local
relapse and the distant metastasis. Brain was the most common metastatic site (10
patients), followed by the liver as the next common site (4 patients). The overall and
progression-free survival rates were 79% and 55% in 1 year, and 45% and 32% in 2
years, respectively, and the median survival was 23 months.
Conclusion : Relatively satisfactory local control and survival rates were achieved after
the combined chemotherapy and radiation therapy with mild to moderate acute
morbidities in limited disease small cell lung cancer.
