|
Despite optimal local therapy such as surgery and/or radiotherapy, the long term outcome is poor for patients with advanced squamous cell carcinomma of head and neck, due to frequent loco-regional recurrence and distant metastases. We studied to determine whether the combination chemotherapy, especially as an adjuvant chemotherapy, would improve the survival of these patients.
Between January, 1986 and December, 1992, 57 patients with previously untreated, locally advanced squamous cell arcinoma of head and neck were assigned to receive 2-3 cycles of induction chemotherapy consisting of 5-fluorouracil(F) and cisplatin(P) every 3 weeks and standard local therapy such as surgery and/or radiotherapy followed by adjuvant chemotherapy with the same FP regimens. Of the 57 enroled patients, 45 patients were evaluable. The obtained results were as following:
1) Among 45 evaluable patients, 18 patients finished all treatment protocol including adjuvant chemotherapy and 27 patients had no adjuvant chemotherapy. The difference of age, sex, performance status, disease stage, and tumor differentiation was not significant statistically between adjuvant chemotherapy group and no-adjuvant chemotherapy group.
2) After induction chemotherapy, 7/45(15.4%), 30/45(67%) achieved complete remission and partial remission respectively with 82.4% overall response rates in entire patients.
3) The 4year progression free survival was 43.3% in adjuvant chemotherapy group and 24.1% in no-adjuvant chemotherapy group(p>0.05). The 4year overall survival was 56.9% and 25.5% respectively(p>0.05). There was no significant different in the patterns of local recurrence and distant metastasis between the two groups.
4) Adverse reactions from combination chemotherapy included nausea, vomiting, mucositis, diarrhea and hematologic bone marrow depression. These were mild and tolerated by patients, and these was no episode of any life threatening toxicities.
In conclusion, adjuvant chemotherapy after induction chemotherapy and local therapy did not show statistically significant survival improvement, but there was trend of prolongation of survival when compared to no adjuvant chemotherapy. Thus, large scale phase III randomized controlled studies are strongly recommended. |
