Sports activity after soft tissue sarcoma of the lower extremity.

Introduction: The aim of this case series was to assess sports activity levels in long-term survivors of soft-tissue sarcomas after multimodal treatment including limb salvaging surgical resection and radio-chemotherapy.Methods: Thirty-two patients (17 f/15 m) with a mean age of 29 (range 10-44) years at the time of diagnosis and a mean follow-up time of 9 (range 3-21) years following sarcoma were included. Ten patients had been diagnosed with liposarcoma, seven with synovial sarcoma, four with fibrosarcoma, three with undifferentiated pleomorphic sarcomas and the remaining eight patients with different soft-tissue sarcoma entities. Sarcoma location of twenty-four (75%) patients was in the thigh, eight (25%) in the lower leg. Eleven (34%) tumors were located epifascial, 21 (66%) in deeper tissue layers. Sports activity was measured by the University of California, Los Angeles (UCLA) Activity Score.Results: One year before treatment 30 patients (94%) and >3 years post-treatment 29 patients (91%)had been pursuing athletic activity regularly. They were performing 5.5 h/week prior and 4.2 h/week >3 years post surgery. The mean UCLA score in case of subfascial sarcomas was 8.0 and thereby lower (p < 0.05) than those of epifascial sarcomas, which were 9.3. Furthermore, the mean UCLA score after subfascial sarcoma resection 3 years postoperative was still below preoperative UCLA levels (p < 0.05), whereas patients after epifascial tumor resection showed no loss of sports activity. No relation between complications and postoperative sports activity level was found.Conclusions: Healthy long-term survivors can achieve high levels of sports activity following limb salvage after soft-tissue sarcomas. The concerned muscle groups may influence the functional and sports outcome and draw attention to this topic in future rehabilitation. This knowledge may be of high value for patients counseling, physicians and orthopedists treating patients, as well as for patients inquiring information regarding post-treatment activity levels.Implication for rehabilitationSport is possible after soft tissue sarcoma treatment and longer-term rehabilitation which is usually three yearsRehabilitation is best undertaken in specialized centersIt is important to maintain contact with surgeons in order to optimize mobilizationHigh impact sports may be affected by deep muscle resections.

Prospective Evaluation of Postural Control and Gait in Pediatric Patients with Cancer After a 4-Week Inpatient Rehabilitation Program.

OBJECTIVE: The aim of the study was to investigate the effects of a 4-wk inpatient rehabilitation program on postural control and gait in pediatric patients with cancer. DESIGN: Eighty-eight patients with brain tumors (n = 59) and bone/soft tissue sarcomas (n = 29) were evaluated. Postural control was assessed examining the velocity of the center of pressure and single-leg stance time on a pressure distribution platform. Walk ratio, a measure of neuromotor control, was used to evaluate intervention effects on gait. RESULTS: Repeated measures analysis of variance showed improvements in postural control measures, indicated by a decrease in velocity of center of pressure of -0.4 cm/sec (F1,80 = 7.175, P = 0.009, ηp = 0.082) and increase in single-leg stance time (mean [median] = 1.1 [2.6] sec, respectively; F1,80 = 12.617, P = 0.001, ηp = 0.136). Walk ratio increased by 0.2 mm/steps per min (F1,82 = 3.766, P = 0.056, ηp = 0.044). Mean changes in dependent variables did not differ between both patient groups (P > 0.05). CONCLUSIONS: The results indicate benefits of an inpatient rehabilitation program comprising standard physical therapy as well as aquatic and hippo therapy on postural control and gait after treatment of pediatric patients with cancer.

Rehabilitation Strategies and Outcomes of the Sarcoma Patient.

Sarcomas are a relatively rare cancer that, depending on the location, can cause significant neuromusculoskeletal dysfunction and require rehabilitation interventions to reduce pain, restore function, and improve quality of life. This review focuses on sarcoma subtypes that frequently cause these complications: bony and soft tissue sarcomas leading to limb salvage or amputation, desmoid tumors, and malignant peripheral nerve sheath tumors. Rehabilitation approaches and outcomes are discussed, as well as considerations for childhood sarcoma survivors transitioning to adulthood.

Massive intercalary reconstruction of lower limb after wide excision of malignant tumors: an alternative to amputation or rotationplasty.

In this study, we present the feasibility of intercalary limb resection and massive reconstruction for malignant tumors of lower extremity. Ten cases of lower extremity malignancies that had undergone concomitant bone (and/or joint) and soft-tissue reconstruction after wide excision exceeding two-thirds of the cross-sectional area of the affected limb were reviewed. All cases were indicated for amputation because of an expansive tumor, hematoma from a pathologic fracture, or previous unplanned excision, with or without critical structure involvement. Bone was reconstructed with either an allograft or a tumor prosthesis. Soft-tissue reconstruction was performed to achieve critical structure and coverage, which was required in all cases. The resection margin was clear in all cases, and no soft-tissue graft failure was encountered. During a mean follow-up of 26 months (range, 9-42 months), no patient developed local recurrence in the resection-reconstruction site. Of the 10 patients, 8 patients were able to walk independently, and two were ambulatory but needed crutch support outdoors. Massive intercalary resection and reconstruction can be an effective treatment option for locally progressed or complicated lower extremity malignancies. Considering patient preference and the fair functional outcomes observed, it may be a useful alternative to amputation or rotationplasty.

Imaging of limb salvage surgery.

OBJECTIVE: Limb salvage surgery comprises surgical techniques designed to resect musculoskeletal extremity tumors and subsequently reconstruct a limb with an acceptable oncologic, functional, and cosmetic result. Today, 70-90% of malignant extremity tumors are being treated with limb salvage surgery. CONCLUSION: The purpose of this article is to describe the operative techniques, review the imaging techniques, and to illustrate imaging findings related to the surgeries in complicated and uncomplicated cases.

Limb salvage for soft-tissue sarcomas of the foot and ankle.

We evaluated the oncological and functional outcome of 27 patients who had limb salvage for a soft-tissue sarcoma of the foot or ankle between 1992 and 2007, with a mean follow-up of 7.5 years (1.05 to 16.2). There were 12 men and 15 women, with a mean age at presentation of 47 years (12 to 84). Referrals came from other hospitals for 16 patients who had previous biopsy or unplanned excision, and 11 presented de novo. There were 18 tumours located in the foot and nine around the ankle. Synovial sarcoma was the most frequent histological diagnosis. Excision was performed in all cases, with 16 patients requiring plastic surgical reconstruction with 13 free and three local flaps. Adjuvant treatment was undertaken in 20 patients, 18 with radiotherapy and two by chemotherapy. Limb salvage was successful in 26 of the 27 patients. There have been two local recurrences and two mesenchymal metastases. Four patients have died of their sarcoma and two of other causes. Function was evaluated with the Toronto Extremity Salvage Score and a mean overall score of 89.40 (52.1 to 100) was obtained. A questionnaire revealed that all surviving patients are able to wear normal shoes and none require a walking aid. Limb salvage can achieve good oncological and functional results with additional treatment.

Rehabilitation after scapulectomy.

An 84-yr-old man presented with right posterior shoulder pain and growing mass. Shoulder range of motion was limited in forward elevation and abduction; result of the neurologic testing was normal. Radiologic workup showed an irregular mass resembling Paget's disease or sarcoma. On surgical inspection, a 16-cm hemorrhagic mass, occupying the entire scapula, was identified. Patient underwent tumor resection and scapulectomy. Postoperatively, he started a rehabilitation program. With attempted ambulation, patient exhibited strong tendencies to lean rightward, walked in circles, and risking fall. The gait abnormality could not be corrected and acute inpatient rehabilitation admission was recommended. A unique rehabilitation program was developed to correct gait deviation, improve balance, and compensate for deficits. After a comprehensive inpatient rehabilitation, the patient was successfully discharged home. We present a review of scapulectomy, postoperative care, and a recommended rehabilitation program.

Prognostic factors for adult sarcomas of head and neck.

The optimal management of adult soft-tissue sarcomas is not clearly established. To assess prognostic factors and survival, the experience of 45 recent successive cases was reviewed. Data were collected from a retrospective database (1993-2005) and statistically analyzed. Rhabdomyosarcomas were excluded. The mean age was 50.1 years; there were 24 men and 21 women. The main histological subtypes were undifferentiated sarcoma (14) and angiosarcoma (10); 21 tumours were grade 3 (46%). The most frequent primary sites were neck muscles (15, 33%) and scalp (11, 24%). At presentation, 5 (20%) cases with lymph-node involvement and another 11 cases (24%) with distant metastasis were observed. The treatment was with curative intent in 33 cases (73%). This entailed surgery, with adjuvant radiotherapy in 15 cases and adjuvant chemotherapy in 5 cases. The 5-year overall survival was 52% (+/-8%). In univariate analysis, the poor prognostic factors were high grade, initial metastasis or lymph nodes, absence of surgery, and number of surgical procedures. In multivariate analysis, two factors remained significant: grade (P=0.006) and absence of surgery (P=0.005). After taking into account grade and metastasis at presentation, quality of surgery has prognostic value. The primary aim of a multidisciplinary approach to these tumours must favour complete resection.

Construct validity of the Enneking score for measuring function in patients with malignant or aggressive benign tumours of the upper limb.

We evaluated the construct validity of the Musculoskeletal Tumour Society rating scale (Enneking score) as a functional measure for patients with sarcoma involving the upper limb. We compared the Enneking score by examining the correlation between two patient-derived outcome measures, the Disability of the Arm, Shoulder, and Hand (DASH) questionnaire and the Medical Outcomes Study Short Form-36 (SF-36) as indicators of functional status in 40 patients with malignant or aggressive benign bone and soft-tissue tumours of the upper limb who had undergone surgical treatment. The frequency distributions were similar among the three scoring systems. As for the validity, Spearman's rank correlation coefficient of the Enneking score to the DASH questionnaire was -0.79 and that of the Enneking to the SF-36 subscales ranged from 0.38 to 0.60. Despite being a measure from the surgeon's perspective, the Enneking score was shown to be a valid indicator of physical disability in patients with malignant or aggressive benign tumours of the upper limb and reflected their opinion.

Endoprosthetic reconstruction for malignant bone and soft-tissue tumors.

BACKGROUND: Nowadays, the results of the management of malignant bone and soft-tissue tumors have been dramatically improved because of the advance in imaging, chemotherapy, radiation therapy, and surgical techniques. Patients can have longer survival times with limb-salvage surgery. Several techniques of reconstruction have been advocated and gained more popularity following malignant tumor resection by using allograft, tumor prostheses, composite allograft prosthesis, or arthrodesis. OBJECTIVE: To report the preliminary results of 32 endoprosthetic reconstructions following malignant bone and soft-tissue tumor resection. The oncologic results, functional outcomes, and complications from the surgery were assessed in the present study. MATERIAL AND METHOD: Since September 1988, the authors have performed 188 limb-salvage surgical operations for the treatment of musculoskeletal tumors at Siriraj Hospital. From March 1994 to July 2006, 32 endoprosthetic reconstructions were performed on 30 patients following malignant bone or soft-tissue tumor removal. There were 16 males and 14 females with a mean age of 28 years (range 10-73). The diagnosis was conventional osteosarcoma in 16 patients, parosteal osteosarcoma in two patients, chondrosarcoma in two patients, leiomyosarcoma in two patients, failed allograft in two patients and one patient each of periosteal osteosarcoma, Ewing's sarcoma, Gorham's disease, synovial sarcoma, malignant fibrous histiocytoma, metastatic renal cell carcinoma, and prosthetic loosening. Wide excision was performed with a mean length of 18.5 cm (range 10-41). Five proximal femurs, 17 distal femurs, 1 total femur 3 proximal tibias, 1 intercalary tibia, 4 proximal humerus and 1 distal humerus were used for reconstruction. Modular replacement systems (MRS, Stryker/Howmedica/Osteonics) were the most common prostheses used in the present series. RESULTS: The mean follow-up time was 26 months (range 6-128.7). Sixteen patients are continuously free of the disease, two are alive with the disease, two had no evidence of the disease, nine died of the disease, and one patient died from complication of hypertension. The mean Musculoskeletal Tumor Society functional analysis for upper extremity reconstruction was 93% (range 86.7-100) and for lower extremity was 89% (range 63.3-100). Two patients (6.7%) were determined to be a failure. Revision due to aseptic loosening was performed in one patient (3.3%) and one hip disarticulation was done related to local recurrence (3.3%). One patient with sciatic nerve palsy and two seromas was found and successfully treated in the present study. CONCLUSION: Endoprosthetic reconstruction could yield satisfactory results as a wide excision and limb-salvage for patients with malignant bone and soft-tissue tumors. Most patients in the present report had good to excellent functions following surgery and few complications occurred in the present report.

Barriers to rehabilitation of patients with extremity sarcomas.

The treatment of most extremity bone or soft tissue sarcomas involves either limb salvage surgery with adjuvant chemoradiation therapy or amputation. The rehabilitation of patients with extremity sarcomas is challenging, and the approach differs depending on the choice of surgical procedure as well as potential-associated medical complications. Early, interdisciplinary rehabilitation involvement is helpful in lessening the impact of expected impairments and disability. There is a lack of evidence examining specific rehabilitation interventions in this patient population. Functional outcomes and quality of life studies suggest overall similar findings between limb salvage patients and amputees, but with differences in various subscales. Rehabilitation interventions are therefore individualized; based on the assessment of medical limitations, functional goals and expectations, and modification of environmental factors. Overcoming medical and oncologic barriers to rehabilitation; as well as psychological, structural, cultural, political, and economic barriers; can serve to lessen the degree of disability.

Rehabilitación implantosoportada en el colgajo libre de peroné / Implant-supported rehabilitation using the fibula free flap

El colgajo de peroné ha demostrado ser el más versatil para la reconstrucción oromandibular, gracias a la gran longitud ósea que podemos utilizar y a la posibilidad de incorporar una amplia paleta cutánea para cobertura de tejidos blandos intraorales.El uso de implantes dentales osteointegrados proporciona un importante método terapéutico para la rehabilitación oral de estos pacientes. Los implantes osteointegrados proporcionan la forma más rígida de estabilización protésica para soportar las fuerzas masticatorias. Estos implantes pueden ser insertados de forma inmediata o diferida. A la hora de utilizar el colgajo libre de peroné realizamos la implantología de forma diferida a los 6-12 meses debido a la gran cantidad de material de osteosíntesis necesaria para la fijación del colgajo. Cuatro o seis meses después, cuando el proceso deosteointegración ha ocurrido, los implantes son cargados con una rehabilitación dental

Free fibula flap has proved to be one of the most versatile for oromandibular reconstruction due to the available length of bone and the possibility of incorporating a long skin paddle to cover intraoral soft tissuesThe use of osseointegrated dental implants is an important technique for the oral rehabilitation of these patients. Osseointegrated implants provide the most rigid prosthetic stabilization available to withstand masticatory forces.These implants can be placedimmediately or in a second time procedure.In our case, implantation in the fibula free flap is done after 6-12 months because of the large amount of osteosynthesis material required forthe fixation of the flap. Four or six months later, when osseointegration has taken place, the implants are loaded with a dental rehabilitation. We analize 12 cases of mandibular reconstruction with fibula free flap and their aesthetic and functional rehabilitation with osseointegrated implants with a 2 year follow up Fifty-six dental implants were placed developing all of them but one a correct osseointegration. All these patients recovered masticatory function and underwent a considerable improvement in labial competence, salival continence,speech articulation and facial harmony

Outcomes of re-excision after unplanned excisions of soft-tissue sarcomas.

BACKGROUND AND OBJECTIVES: Unplanned excisions of soft-tissue sarcomas of the extremities occur commonly. Our goal was to evaluate the presence of residual disease, the treatment outcomes as they relate to local and distant recurrence and 5-year survival, and the limb functional outcomes in patients with unplanned sarcoma excision who were treated with re-excision and adjuvant therapy. METHODS: Between 1993 and 1999, 42 patients presented to our institution after unplanned excision of soft-tissue sarcomas. Of those 42 patients, 38 without gross residual disease or metastatic lesions formed the basis of this review. All 38 patients underwent revision wide excision; most (31) also received adjuvant therapy (radiation and/or chemotherapy). Clinical data were obtained from analysis of patient records and radiographic studies. Univariate analysis was performed with logistical regression, and multivariate analysis was performed with Cox modeling. RESULTS: The overall 5-year survival rate was 91.3% and the disease-free 5-year survival rate was 82.2%. Univariate analysis showed that stage-III disease (American Joint Committee on Cancer classification of soft-tissue sarcomas), lesions below the fascia, a histologic high-grade, and the development of organ metastasis were statistically significant factors for mortality. Stage-III disease also was significant for mortality on multivariate analysis. Only stage-III disease was significant for the development of local recurrence. Eighty-four percent of the patients had good to excellent functional outcomes. CONCLUSIONS: Re-excision with adjuvant therapy proved to be a safe and effective method for treating the disease and preserving limb function.

Rehabilitation and quality-of-life issues in patients with extremity soft tissue sarcoma.

The current standard of care for soft tissue sarcoma (STS) is limb salvage surgery and adjuvant radiotherapy, with long-term survival rates of approximately 70%. However, the extensive surgical resection and subsequent reconstruction result in 50% of survivors living with chronic disability. Rehabilitation aims to optimize functional independence and quality of life, and is routinely offered to patients undergoing surgical treatment for STS. Unfortunately, there is a dearth of research related to rehabilitation in this area. We propose a model for assessing disability, for designing treatment interventions and for evaluating rehabilitative outcomes in STS. The World Health Organization's (WHO) international classification of functioning, disability, and health (ICF) is divided into three domains: 1) impairments (related to body structure and function), 2) activity limitations (related to usual self-care activities/activities of daily living), and 3) participation restrictions (related to social roles). A literature review of STS rehabilitation reveals that most studies have focused on disability assessment, with few papers describing or evaluating rehabilitation interventions commonly employed in STS. Clinicians are forced to extrapolate findings from other patient populations in order to evaluate the effectiveness of specific rehabilitation strategies (ie, those used for particular sequelae of STS, such as lymphedema or impaired exercise tolerance). There is strongest support for complex decongestive physiotherapy (targeting lymphedema) and aerobic exercise interventions (aimed at alleviating cancer-related fatigue and psychosocial sequelae). The most poorly researched topic is rehabilitation for genitourinary disability (both incontinence and sexual dysfunction). Most studies related to oncologic rehabilitation are restricted to the impairment level (eg, affecting range of motion, muscle strength) of the ICF, with only a small minority addressing activity limitations (eg, affecting activities of daily living) experienced by patients. A consideration of participation restrictions (eg, fulfillment of vocational roles) is almost wholly absent from the literature. Yet social role reintegration is of fundamental importance to patients. Further research is required in these two domains. The ICF provides a comprehensive framework for future research into rehabilitation interventions for STS.

Outcome of lower extremity malignancy survivors treated with transfemoral amputation.

OBJECTIVE: To determine outcomes of surviving patients who underwent transfemoral amputation as part of treatment for lower extremity malignancy at a mean 15 years postoperatively, with a minimum 2-year follow-up. DESIGN: Retrospective, case control. SETTING: Tertiary care university medical center. PATIENTS: Thirty-five of 38 consecutively admitted patients free of metastatic disease managed with transfemoral amputation as part of treatment of a lower extremity bone and/or soft tissue malignancy between 1966 and 1997 at 1 institution. The control group included 35 age- and gender-matched subjects recruited from the local driver's license office. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Musculoskeletal Function Assessment (MFA), Short Form-12 General Health Status Survey (SF-12), physical performance battery, cost, and demographic data. RESULTS: Controls showed superior scores as measured by the MFA (P < .0001), the physical component summary of the SF-12 (P = .0002), and the physical performance battery (P < .0001), but had inferior scores on the mental component summary of the SF-12 (P < .0001). With the numbers available, no differences were found between study and control subjects in terms of employment rate (P = .51), education level (P = .66), income level (P =.44), marital status (P = .79), incidence of self-reported health problems (P = .14), and alcohol (P =.42) and tobacco (P = .82) use. Ten patients were included in the cost analysis; the mean cost to obtain and maintain a lower extremity prosthesis was $4225 per year (range, 623 dollars-8517 dollars). CONCLUSIONS: Although the decrease in physical performance was anticipated in the study group, the group differed very little from the control population in terms of employment, education level, income, marital and home status, incidence of self-reported health problems, incidence of self-reported depression, and alcohol and tobacco use. Also, the long-term cost of maintaining a lower extremity prosthesis is noted.

Walking ability and activities of daily living after limb salvage operations for malignant bone and soft-tissue tumors of the lower limbs.

We evaluated the number of steps, activities of daily life (ADL) score, Enneking score, active range of motion and muscle strength by muscle manual testing for function in lower limbs after reconstructive procedures in surgical treatment of tumors. The 56 patients with 20 malignant bone tumors and 36 malignant soft-tissue tumors averaged 7119 +/- 3563 steps per day, or 69.8% of the control group. The average ADL score of patients was 14.0 +/- 4.1 points (70.0%), and the average Enneking score 20.4 +/- 6.0 points (68.0%). The scores of the bone tumor group were lower than those of the soft-tissue tumor group. These scores were not correlated with the range of motion. The number of steps and ADL score were correlated with Enneking score (coefficient 0.52 and 0.84, respectively). The number of steps and the ADL score appear to be useful, as is Enneking score.

Functional outcome in extremity soft tissue sarcoma.

The studies reporting functional outcome for patients undergoing limb preservation surgery for extremity soft tissue sarcoma (STS) have evaluated mainly impairments, that is, deficits at an anatomic structure level, such as joint range of motion and strength. Disability, activities of daily living, self-care, and mobility have been less frequently evaluated. Review of the literature suggests that approximately 50% of patients treated for STS have significant impairments, whereas the frequency of disability is less. Synthesis of the results is difficult because of the heterogeneity of patient samples, treatment, and the outcomes used to evaluate function. Future studies require the use of standardized definitions and reliable and valid functional outcome measures. Improved patient outcomes can be achieved only by understanding the determinants of these outcomes and by introducing interventions to improve patient functional outcome.

Functional outcome in amputation versus limb sparing of patients with lower extremity sarcoma: a matched case-control study.

OBJECTIVE: To quantify the differences in physical disability and handicap experienced by patients with lower extremity sarcoma who required amputation for their primary tumor as compared with those treated by limb-sparing surgery. DESIGN: Matched case-control study. Twelve patients with amputation were matched with 24 patients treated by limb-sparing surgery on the following variables: age, gender, length of follow-up, bone versus soft-tissue tumor, anatomic site, and treatment with adjuvant chemotherapy. PATIENTS: Patients who underwent above-knee amputation (AKA) or below-knee amputation (BKA) for primary soft-tissue or bone sarcoma, who had not developed local or systemic recurrence, and who had been followed up for at least 1 year since surgery. MAIN OUTCOME MEASURES: The Toronto Extremity Salvage Score (TESS), a measure of physical disability; the Shortform-36 (SF-36), a generic health status measure; and the Reintegration to Normal Living (RNL), a measure of handicap. RESULTS: Mean TESS score for the patients with amputations was 74.5 versus 85.1 for the limb-sparing patients. (p = .15). Only the physical function subscale of the SF-36 showed statistically significant differences, with means of 45 and 71.1 for the amputation versus limb-sparing groups, respectively (p = .03). The RNL for the amputation group was 84.4 versus 97 for the limb-sparing group (p = .05). Seven of the 12 patients with amputations experienced ongoing difficulty with the soft tissues overlying their stumps. CONCLUSIONS: There was a trend toward increased disability for those in the amputation group versus those in the limb-sparing group, with the amputation group showing significantly higher levels of handicap. These data suggest that the differences in disability between amputation and limb-sparing patients are smaller than anticipated. The differences may be more notable in measuring handicap.
