Abstract
Purpose
The purpose of this study is to compare general survival rate and survival rate according to expectable prognostic factors by analyzing the result of treating a patient of squamous cell carcinoma.
Materials and Methods
From Mar. 1999 to Feb. 2011, 151 patients were pathologically confirmed as squamous cell carcinoma of limbs and body in our hospital, and among those patients, 51 patients underwent the surgical treatment. This study included 41 patients who underwent the surgical treatment and were followed-up for more than 12 months. The mean age of population was 64.4 years. 31 males and 10 females were included. Wide excision with following skin grafts or flaps for reconstruction (29 cases) was mostly performed, but amputation (12 cases) was also performed for cases with extremities where resection margin was difficult to obtain and cases with neural or vascular invasion. 8 patients underwent chemotherapy or radiotherapy after resection, and 33 underwent the operation only. Stages were classified by AJCC Classification, survival rate was calculated by Kaplan-Meier method and survival rate of groups was compared by Log-rank test. For the expectable prognostic factors related to survival rate, location of primary lesion, cause of disease, pathologic grade, staging, surgical method, additional anticancer therapy were examined and each survival rate was compared.
Results
The average follow-up period was 65.2 (12-132) months. Thirty patients survived out of 41 patients till last follow up. The overall survival rate in 5 years was 77%. Three cases (7.3%) had local recurrence, and 7 cases (17.0%) had metastasis. The average period of recurrence from operation was 27 (18-43) months. Possible prognostic factors such as location of primary lesion, cause of disease, pathologic grade, staging, additional anticancer therapy showed no significant difference in survival rates. However, patients with amputation showed significantly lower survival rate than those with wide excision.
Figures and Tables
Figure 1
(A) Forty one-year old male got an open wound on his left buttock 5 years ago, and that was not healed so far. It was diagnosed as squamous cell carcinoma at a local clinic. (B) Wide excision was done. (C) Local transposition flap on left thigh, meshed skin graft was done.
Figure 2
(A) Fifty year-old male had suffered from post-burn scar contracture from right axilla to forearm, and marjolin's ulcer of right forearm since he got burned 40 years ago. They were diagnosed as squamous cell carcinoma at a dermatologist's office. (B) Above-elbow amputation, and release of burn-scar contracture on right axilla was done. (C) Skin graft was done.
