In the treatment of sarcoma, the reconstructive surgeon must consider not only limb salvage but also functional reconstruction. The aim of this study was to evaluate a functional reconstruction of a dorsal forearm defect after sarcoma resection using immediate tendon transfer. Patients who underwent reconstruction of a dorsal forearm defect after sarcoma resection with an immediate tendon transfer between 1997 and 2019 at our hospital were included in this retrospective study. Patient demographics, tumor characteristics, surgical characteristics and functional outcomes were examined. Nine patients were included in this study. Tendon transfer of the flexor carpi radialis (FCR) or the flexor carpi ulnaris (FCU) to the extensor digitorum communis (EDC), the brachioradialis (BR) to the EDC, and the palmaris longus (PL) tendon to the extensor pollicis longus (EPL) was performed in seven, two and five patients, respectively. Seven patients underwent reconstruction using a free flap. Neither anastomosis complications nor infections were encountered. Partial flap necrosis and donor site dehiscence were seen in one case each. The mean distal interphalangeal (DIP), proximal interphalangeal (PIP) and metacarpophalangeal (MP) joint active extension were 4.4°, 6.1° and 11.1° postoperatively. The mean Musculoskeletal Tumor Society (MSTS) score was 26. Immediate tendon transfers of the FCR or the FCU to the EDC and the PL tendon to the EPL can be considered an optimal functional reconstruction of a dorsal forearm defect after sarcoma resection.

Background: In the setting of the reconstruction for a large defect, we must make the maximum use of the limited human tissue with the minimum damage. In this article, we report on reconstruction using a combination of three-skin paddle latissimus dorsi and a scapular flap for a large defect after soft tissue sarcoma resection to minimize donor site morbidity., Methods: From 2000 to 2012, six patients underwent primary reconstruction using free or pedicled triple-lobe combined latissimus dorsi and scapular flap after wide resection of soft tissue sarcoma. There were five male patient and one female, and their average age was 66.8 (range, 49-80 years). The location of the defects was the thoracic wall in three, the thigh in one, the knee in one, and the shoulder in one. The average size of the defect was 18.8 × 13.9 cm., Results: The average size of the ascending scapular flap and the skin paddle of the latissimus dorsi flap was 6.8 × 13 cm and 7.3 × 14.7 cm. One patient had partial necrosis of the skin paddle of the latissimus dorsi flap, which was treated conservatively. The triple-lobe combined latissimus dorsi and scapular flaps survived completely in five cases. Neither anastomosis complications nor infections were encountered. The average follow-up period was 63.67 months. All patients were satisfied functionally and esthetically with the reconstruction outcomes at the end of follow-up., Conclusion: In conclusion, the triple-lobe combined latissimus dorsi and scapular flap is one of the options for reconstruction of a large defect after sarcoma resection to minimize donor site morbidity., (© 2020 Wiley Periodicals LLC.)

We present the current perspective on reconstructive surgery for soft tissue tumors, especially in the extremities, based on our large series. A total of 1,813 patients with bone and soft tissue sarcomas underwent surgery at our hospital between 1978 and 2011. Reconstructive operations were performed by plastic surgeons. In such reconstructive surgery, to achieve better quality of life for the patient, great effort was made not only for limb salvage but also for functional reconstruction. Although a few surgeries resulted in limb amputation due to multiple tumors, recurrence, or advanced age of the patient, the rate of limb salvage and/or functional recovery has been increasing dramatically using the method of flap surgery and vascular reconstruction. In fact, over more than 30 years, the limb salvage rate at our hospital has increased from 71.6 % around 1980 to 90.5 % around 2010. In this article, we describe our experience in plastic and reconstructive surgeries after operation for bone and soft tissue sarcomas.

The defects following soft-tissue or bone malignancies resection tend to be wide and composite at the region of ankle, and reconstruction of the defects is a difficult task. Between 1982 and 2007, we performed reconstruction for the defects of the ankle region in seven patients. All of the patients underwent free tissue transfer, and the selected methods are different for each case. No perioperative complications have occurred in any patients. All flaps survived completely. Two patients had local recurrence and amputation was carried out. Functional and aesthetical improvement is desirable for reconstruction of the ankle. We consider it important to select reconstructive options based on the size and volume of the defects and tissue deficiency; and free tissue transfer is useful for the reconstruction of the wide and composite defects at the ankle region., (Copyright 2009 British Association of Plastic, Reconstructive and Aesthetic Surgeons.

In free tissue transfers, preventing microvascular thrombosis is the first priority to achieve a successful result. Numerous protocols exist for preventing thrombosis postoperatively. We performed continuous local intraarterial infusion of anticoagulants in 11 patients undergoing wide resection of malignant soft tissue tumors, followed by primary microvascular reconstruction in the lower limb. A catheter designed for epidural anesthesia was inserted into the femoral artery and connected to a syringe pump. A daily dose of 100 ml comprising 2,000 U of heparin and 40 microg of prostaglandin E(1) was administered by means of continuous infusion for seven consecutive days as a standard regime. There were no cases of thrombosis during the continuous local intraarterial infusion of anticoagulants. There were no serious systemic complications. Although we have described limited cases and supporting data are lacking, we feel that this procedure might be useful for microsurgical reconstruction of the lower limb., ((c) 2010 Wiley-Liss, Inc.)

Preoperative therapy effects, resected margin and local radicality were investigated in 40 cases of soft tissue sarcoma in which preoperative therapy (mainly radiation therapy) had been given. The results indicated that there was no effect upon prognosis due to postponement of surgery in order to perform preoperative treatment. In cases in which radiation therapy was used for preoperative treatment, even when a surgical margin resulted with in a tumor, no recurrence was found. However, histologically there was concern that some portion of the living tumor cell in marginal area of the tumor might have remained. Thus, at the present stage in cases having undergone initial treatment, radiation limited to the specific area of the resected margin causing non-curative margin should be given. If combined with preoperative radiation therapy, surgical intervention involving "wide margin" can be considered radical. On the other hand, cases having undergone surgery before and receiving preoperative therapy that show good response nevertheless show numerous recurrences. These recurrences, however, invariably occur outside of the irradiated area, and may be attributed to the fact that tumor cell dissemination from the earlier surgery was not within the radiation field. Hence, it was considered that the area for radiation in the case of a recurrence should extend well beyond the scar area.
