ABSTRACT
Objective To evaluate the local recurrence rate,limb function and complications of soft tissue sarcoma of thigh after muscle group resection.Methods Between January 2009 and August 2016,twenty-threepatients who were diagnosed as soft tissue sarcoma for the first time in our hospital,receiving thigh quadriceps muscle group resection,adductor muscle group resection or posterior compartment of the thigh resection were incorporated into this study.Patients who had received surgery of this lesion before,suffered from recurrent soft tissue tumor,had tumor involved multiple muscle groups which could not be resected completely,had sciatic nerve or femoral artery or vein affected by tumor or had distal metastasis were excluded.This retrospective study consisted of 12 male and 11 female.The age ranged from 20-80 with the average of 52.All the patients received CT and MRI of thigh to figure out the size of tumor,the invaded extension of the lesion and the specific muscle group involved.Chest CT scan and ultrasound of bilateral inguinal lymph nodes were arranged to exclude the tumor metastases.After all these examinations were done,needle biopsy with the guidance of CT scan was performed for the pathological diagnosis.The pathology included undifferentiated pleomorphic sarcoma (7 cases),rhabdomyosarcoma (2 cases),primitive neurotodermal tumor (1 case),synovial sarcoma (1 case),leiomyosarcoma (3 cases),fibrosarcoma (5 cases) and liposarcoma (4 cases).Sixpatients received quadriceps muscle group resection,eightpatients received adductor muscle group resection and the other 9 patients received posterior compartment of the thigh resection.Patients with undifferentiated pleomorphic sarcoma,leiomyosarcoma,primitive neurotodermal tumor and synovial sarcoma received postoperative adjuvant chemotherapy.None of patients received radiotherapy.After surgery,drainage tube of negative pressure was placed until the volume of drainage was less than 50 ml within 24 h.The affected thigh was bound up tightly.Intravenous antibiotics were used for 3 days to prevent from postoperative infections.Patients received quadriceps muscle group resection stayed in the bed for 4 weeks.After that they could walk with the protection of orthosis with unbending position.Other patients got out of bed after 2 weeks.All the complications after surgery were recorded.Reexaminations were arranged in 3,6,12 and 24 months after surgery separately.After that,reexamination was arranged every half a year.Chest CT scan was used to detect lung metastasis and ultrasound or MRI was arranged for local recurrence.Lower limb function after surgery was evaluated by MSTS scores.Results All the surgeries of muscle group excision were successfully completed.The duration of surgery ranged 1.5-3.5 h with the average of 2.2 h.The bleeding volume during surgery ranged 100-1 100 mL with the average of 313 mL.The follow-up was a mean of 41 months (range,17-108 months).None was lost to follow-up.The local recurrence rate was 4.3% (1/23).One patient with undifferentiated pleomorphic sarcoma had positive surgical margin,who received posterior compartment of the thigh resection.Local recurrence occurred 6 months after surgery.Then he received expanded resection.Six patients had distant metastases,five patients for lung metastases,one patient for lung and inguinal lymph node metastases.Of these,five patients had died and one lived with the metastasis.The median MSTS score was 26.3 points (range,14-30 points).Specifically,the median musculoskeletal tumor society (MSTS) score was 28 points (range,21-30 points) for 9 patients with posterior compartment of the thigh resection,twenty-nine points (range,27-30 points) for 8 patients with adductor muscle group resection,and 20.3 points (range,14-24 points) for 6 patients with quadriceps muscle group resection.Five patients had complications,including local recurrence (1 case),hematoma (2 cases) and cutaneous necrosis (2 cases),all of which were settled by reoperation.The rate of complication was 21.7%.Conclusion Muscle group resection is an effective surgical treatment for soft tissue sarcoma of thigh,which could reduce the risk of local recurrence,apart from quadriceps muscle group resection,the other two muscle group resections have limited impact on lower limb function,additionally,thigh muscle group resection is a safe procedure with few complications.
