| ABSTRACT |
|
A total of 72 patients with limited stage small cell lung cancer treated with combination of chemotherapy and radiotherapy at Department of Radiation Oncology, Yonsei University College of Meidcine between Jan. 1975 and Dec. 1986 were retrospectively analysed. 1) Age distribution of patients was between forty and seventy-one with median age fifty-five and male to female ratio was 5:l. 2) Complete response rate by treatment modality was as follows; CV+RT was 33.3%; CAV+RT, 43.59o, MOCA+RT. 28.6% and CAV+VP+RT was 62.5%. CAV+VP+RT group showed best result and this was statistically significant to MOCA+RT group (p=0.02) but insignificant to CV+ RT or CAV+RT grouP (P>0.1). 3) Median survival and 5 year actuarial survival rate by treatment modality were as follows; CVt RT was 15 3 months and 16.2%. CAV+RT, 14months and 16.396; MOCA+RT, 7month and 09; and CAV+ VP+ RT was 24 month and 30.7% respectively. CAV+VP+ RT groulp shawed the best results and these were statistically significant to MOCA+RT group(p<0.05) but insignificant to CV+RT or CAV+RT group (p>0,05). 4l Patterns of failure in complete response group were as follows; local failure was 24%, distant failure, 52% and local and distant failure was 24%. 5) Local control rate by radiation dosage in complete response group was as follows; when total dose of 4500-4900 cGv was given, local control rate was 50%; 5000 cGy, 43% however when total dose was given between 5100-7000 cGy, local control rate was significantly improved to 100%. 6) The incidences of brain metastsis in PCI (prophylactic cranial irradiation) group and control group were 20% and 32% respectively, although this was statistically insignificant (p=0.32). 7) Statistically significant factors affecting prognosis were performance status, TNM stage, initial status of presentation of superior vena cava syndrome and pleural effusion, location of tumor, response status to treatment and whether or not maintenance chemotherapy is added. |
