Purpose: We performed a retrospective analysis to compare short term results of induction chemotherapy-radiotherapy versus concurrent chemo-radiotherapy in patients with locally advanced nasopharyngeal carcinoma.
Materials and Methods: From Oct. 1989 to May 1998, 62 patients with locally advanced
nasopharyngeal carcinoma were treated with induction chemotherapy followed by
radiotherapy (induction group) or concurrent chemo-radiotherapy (concurrent group).
Induction chemotherapy was done for 50 patients, and concurrent chemotherapy for 12
patients. Age, sex, performance status, and pathologic types were evenly distributed
between two groups. Stage distribution showed 32% with ¥±B, 30% with ¥², and 38%
with ¥³in induction group, and 50%, 33.3%, and 16.7% in concurrent group, respectively
Chemotherapy regimen was CF(cisplatin and 5-FU) in both groups, and drug delivery
method also same. Cisplatin 100 §·/m2 was intravenously infused on day
1, and 5-FU 1,000 §·/m2 on day 2~6. This was repeated at 3 weeks
internal. At the end of radiotherapy, total cycles of chemotherapy were 1~3 (median2) in
both groups. Conventionally fractionated radiotherapy with daily fraction size 1.8~2.0 Gy
and 5 fractions/week was done. Total dose was 69.4~86 Gy(median 73.4 Gy) for
induction group, and 69.4~75.4 Gy(median 70.8 Gy) for concurrent group. Follow-up time
was 9~116 months (median 40.5 months) for induction group, 14~29 moths (median 21
moths) for concurrent group, respectively.
Results: Overall 2 year survival rate (2YSR) for all patients was 78.7%. According to
treatment modality, 2YSR were 77% for induction group, 87% for concurrent group
(p>0.05). 2 year disease-free survival rate were 56% and 81% (p>0.05), respectively.
Complete response to treatment were 75.5% for induction group and 91.7% for
concurrent group, but there was no statistical difference. The incidence of grade 3~4
hematologic toxicity during radiotherapy was not differ between two groups, but grade 2
leukopenia was more frequent in concurrent group (18% vs 66.7%). Grade 3~4 mucositis
was more frequent in concurrent group (4.0% vs 33.3%). Overall incidence of grade 3~4
acute toxicity during radiotherapy was more frequent in concurrent group (6.0% vs
41.7%, p=0.005).
Conclusion: concurrent chemo-radiotherapy showed a trend of improvement in
short-term survival and in treatment response when compared with induction
chemotherapy-radiotherapy in locally advanced nasopharyngeal carcinoma. More
controlled randomized trial are needed
