Purpose: This study was designed to investigate the clinical and oncological results of the unplanned excision group, and to compare the results with those of the planned excision group.
Materials and Methods: A total of 41 patients who underwent re-excision of sarcoma in Yeungnam University Medical Center, from January 2000 to December 2012, after unplanned excision in local medical centers were reviewed retrospectively. We analyzed the clinical and oncological results according to age, gender, tumor size, depth, and locations. As a control group of planned excision, 81 patients with a similar state, were selected and reviewed among the group of 480 patients who underwent planned excision during the same period. We then compared the results of the two groups.
Results: In the unplanned excision group, only the age factor was statistically significant to survival (p=0.048). In comparison of clinical and oncological results of the unplanned and planned excision groups, recurrence rate was 11.1% in the unplanned group, 10.5% in the planned group and did not show statistical significance (p=0.18). Survival rate was 74% in the unplanned group, 76.6% in the planned group and did not show statistical significance (p=0.06). Necessity of additional surgery for coverage of soft tissue defects was 46% in the unplanned group, 14% in the planned group and showed statistical significance (p=0.00).
Conclusion: No significant difference in survival and local recurrence rate was observed between the groups of re-excision with microscopic remnant tumor after unplanned excision and planned excision. However, unplanned excision might lead to unnecessary additional surgery like skin-graft, skin-flap if it were planned.
