Malignant bone and soft tissue tumors of the shoulder girdle a retrospective analysis of 30 operated cases

From 1988 to 1995, 30 patients (16 men) with malignant bone (n 23) and soft tissue (n 7) tumors of the shoulder girdle underwent surgery in our department. The mean age was 34 (6-80) years. 26 patients had primary and 4 had metastatic lesions. The average follow-up period was 3 (2-8) years, at the end of which 18 patients showed no evidence of disease, 2 were alive with disease, and 10 had died (9 because of tumor).

25 of the operations were limb-sparing procedures, while the other 5 were major amputations. Radical resection was performed in 4 patients, wide resection in 25 and marginal resection in 1. Local recurrence was observed in 2 patients.

10 patients with stage IIB tumors of the proximal humerus underwent extraarticular humeral and glenoid resection. Reconstruction was performed with either a modular or an improvised implant. Following surgery, those patients had a concave contour of the shoulder and poor abduction ability. Overall functional outcome was good in 18 patients, moderate in 11 and poor in 1. No correlation was found between functional outcome and reconstruction technique.     

Reverse sural artery flap: a reliable alternative for foot and ankle soft tissue reconstruction

Reconstruction of soft tissue injuries of the foot and ankle with microsurgical techniques

Microsurgical reconstruction for injuries of the foot and ankle includes, in addition to repair of small nerves, vessels, and tendons, coverage of soft tissue defects. Local transpositional and island pedicle flaps are ideal when available and adequate. The choice of free vascularized flaps is based on its potential durability, contour, bulk, and appearance. Thin cutaneous flaps, fascial flaps, and muscle flaps covered with split thickness skin grafts are appropriate in specific areas. Neurosensory flaps and methods of reinnervation may have a place in extensively denervated feet. Good postoperative pedorthic care aids in the final outcome.

Differentiation between sarcoma and benign lesions is imperative when presented with any mass in the foot or ankle.     

骨与软组织肿瘤活检现状

骨与软组织肿瘤的诊断是一个多中心的复杂过程,病理学检查是诊断的金标准。术前活检能够明确骨与软组织肿瘤的诊断,指导进一步最终确定手术方式、是否放化疗和判断患者预后。现在常用的活检方式有切开活检、经皮穿刺活检(包括细针穿刺活检和空芯针穿刺活检),当前文献没有明确推荐的首选活检方式。本文将三种活检方式进行综述,供临床参考。     

Clinical significance of thallium-201 scintigraphy in bone and soft tissue tumors

 We evaluated sequential thallium scans on both early images (EI) and delayed images (DI) for 62 patients who had bone and soft tissue lesions. The purpose was to determine whether this technique could be used to ascertain accurately whether lesions were malignant or benign and to predict the response to chemotherapy. The thallium-201 chloride (²⁰¹Tl) accumulation in malignant tumors and benign lesions was statistically different. Sensitivity, specificity, and accuracy for ²⁰¹Tl scans in detecting malignant tumors was 94%, 65%, and 82%, respectively, for EI, and 94%, 85%, and 90%, respectively, for DI. On multivariate analysis, significant independent factors for ²⁰¹Tl uptake were malignant lesions on EI and DI and high cellularity on EI. Thirteen patients with malignant bone and soft tissue tumors underwent ²⁰¹Tl scans before and after preoperative chemotherapy. There was a good correlation between percentage of tumor necrosis and percentage change of accumulation in lesion-to-normal tissue ration, and the correlation coefficient was higher on EI (r= 0.801) than on DI (r= 0.664). These results support the notion that ²⁰¹Tl scintigraphy, although showing some false-positive and false-negative findings, is a useful tool in the evaluation of either malignant tumors or benign lesions. Furthermore, ²⁰¹Tl scans on EI provide benefit concerning the evaluation of chemotherapeutic response in patients with malignant bone and soft tissue tumors.

应用皮肤牵张带治疗足踝部皮肤软组织缺损

目的探讨皮肤牵张带(externaltissueextender,ETE)在治疗足踝部皮肤软组织缺损中的价值。方法2001年7月～2003年2月,应用皮肤ETE治疗8例足踝部软组织缺损患者,男6例,女2例;年龄5～85岁,平均51.6岁;非缺血性糖尿病足3例,右踝部外伤性皮肤缺损跟骨外露2例,左外踝皮肤溃疡1例,类风湿性关节炎行左踝关节融合术后伤口不愈合1例,右足背皮肤缺损跖骨外露1例;软组织缺损面积最大为5.0cm×12cm,最小为3.5cm×3.5cm。于伤口的两侧标记皮肤ETE的进针点和出针点,每针相隔1.8cm,距伤口边缘0.5cm。治疗期间每天牵拉硅胶带1～2次以维持合适的张力,直至伤口合拢。结果8例患者均获得随访,随访时间2～20个月,平均5个月。其中7例痊愈,1例类风湿性关节炎行左踝关节融合术后伤口不愈合的患者(伤口5cm×3.5cm)经皮肤ETE治疗后仍未愈合,考虑与长期应用激素,创口周缘皮肤所含胶原萎缩,所能承受的张力小有关;另外患者在治疗过程中出现伤口感染,致牵张的皮肤裂开,患者自动出院,随访半年仍未愈合。结论应用皮肤ETE治疗足踝部皮肤软组织缺损,手术时间短,对患者造成的局部损伤小,术后恢复快,尤其适用于老年非缺血性糖尿病足部溃疡患者。     

Diagnosis of malignant bone and soft tissue tumors

Primary sarcoma of bone is a rare entity but nevertheless a significant cause of mortality in children and adolescents. The focus of the preoperative evaluation is to set up a histological diagnosis, define local tumor extent and develop a therapy regimen. In addition to patient history and clinical findings a radiograph in two orthogonal planes is still of great importance. MRI plays a major role in the further clarification of the diagnosis, while CT is valuable in the diagnosis of tumors of the axial skeleton as well as in systemic staging. A PET-CT can be performed to obtain an overview of further tumor sites. Open bone biopsy is the final diagnostic step and should be carried out at the institution where the definitive treatment will be performed. Complications such as fracture, neural lesions and spread of tumor cells are relatively rare if the biopsy is performed appropriately; however, patients should be instructed to strictly avoid weight-bearing on the affected extremity.     

Clinical diagnosis of soft tissue tumors

In the clinical diagnosis of a soft tissue tumor, it is important to determine whether the lesion is malignant as soon as possible. To establish such a diagnosis we perform aspiration cytology and needle biopsy simultaneously with computed radiography (CR) and echosonogram at the first visit. After the first day's investigations, it is usually possible to select the surgical procedures based on the working diagnosis in almost all patients. When the lesion is clearly benign by diagnosis, excision can be performed. For large lesions or lesions that are suspected to be malignant, CT, magnetic resonance imaging , isotope-investigation, and arteriography are also performed, effectively providing precision in an already established diagnosis. These imaging findings are useful for establishing a surgical plan by anticipating the surgical line of the safety margin. For these few patients in whom the diagnosis still remains uncertain or when preoperative treatment is planned, an incisional or excisional biopsy may be necessary to establish the final diagnosis. When preoperative treatment is performed, the effectiveness of this treatment can be evaluated by medical imaging. Received for publication on Nov. 16, 1997     

An epidemiological review of 623 foot and ankle soft tissue tumours and pseudo-tumours

BackgroundIn evaluating foot and ankle soft tissue masses, comprehensive epidemiological data, especially clinical predictors of malignancy, is essential knowledge. Our aim was to assess these data in a cohort of patients that have undergone surgical excision of foot and ankle soft tissue tumours and pseudo-tumours over a 10-year period.MethodsA retrospective review of foot and ankle soft tissue tumours and pseudo-tumours excised in a tertiary hospital from 1 Jan 2006 to 31 Dec 2016 was performed. Uni- and multivariable analyses via logistic regression were conducted for all independent variables to identify their relationship with malignancy. Applying receiver operating characteristic (ROC) curves and Youden’s Index to significant variables, we attempted to identify optimal threshold values to predict malignancy of the soft tissue mass.ResultsA total of 623 tumours and pseudo-tumours were analysed, and majority were benign (n = 605, 97.1%). The most common pseudo-tumour, benign, and malignant tumours were ganglion cysts (n = 289, 90.3%), plantar fibromas (n = 54, 18.9%) and pleomorphic undifferentiated sarcomas (n = 4, 22.2%), respectively. Increasing age (P = 0.036), larger size of mass (P < 0.001) and male gender (P = 0.017) were significant predictors of malignancy. ROC and Youden’s Index analyses identified optimal threshold values of 4.0 cm (area under curve [AUC] = 87.6%) for size of mass and 66 years (AUC = 60.7%) for age.ConclusionMajority of foot and ankle soft tissue masses are benign. Increasing age, larger size of mass and male gender are significant predictors of malignancy. The threshold value in predicting malignancy is 4.0 cm for size of mass and 66 years for age.
