salvage method for unplanned excision of soft tissue sarcoma longterm results of secondlook surgery following radiohyperthermochemotherapy we have established a secondlook operation protocol that consists of whole biopsy of surgical scar tissue following radiohyperthermochemotherapy rhc after unplanned excision of soft tissue sarcoma out of 30 patients who underwent rhc for soft tissue sarcoma at our institution 6 were enrolled into this study to undergo a secondlook operation for unplanned excision radiotherapy was given to a total dose of 32 gy hyperthermia was conducted once a week for a total of five sessions chemotherapy was performed at weekly intervals surgery was performed to excise the scar tissue that was enhanced on preoperative mri in all six cases no residual tumors were identified in resected scar tissue thus no additional wide excision was performed the average followup period was 109 years there were no local recurrences and all patients were alive at their final followup longterm followup confirmed that rhc can replace additional wide excision for unplanned excision of soft tissue sarcoma
