The gold standard of treatment for LMS tumors is surgery. If it is at all possible, surgical resection with wide clear margins is the treatment of choice for any LMS presence. If surgical resection is not possible, then locally advanced or metastatic spread within a limb can be treated either systemically or locally. If there is metastatic spread beyond the limb, then a systemic method would probably be best to start with. Some systemic options are chemotherapy, antiangiogenesis treatment, targeted molecular therapy, immunological. Look under the Treatments Techniques section for discussions of some of the systemic options. If the only tumor presence known is in the limb, however, you have the choice of localized treatment. The advantage of localized treatment is that it spares the rest of the body. This page investigates some localized treatments.

| Isolated Limb Perfusion |
|
For LMS, unquestionable indications are for Surgical Resection if at all possible. For non-resectable metastases other treatments must be explored [RFA, conventional chemotherapy, and so on.]. Where conventional systemic chemotherapy is chosen, but is ineffective, there are alternative methods of delivering the chemotherapy agent that maximizes tumor exposure. For instance, Chemoembolisation can provide the tumor with high drug concentrations without provoking systemic side effects. These procedures do not prevent the appearance of extra-regional recurrence or metastases. Isolated limb perfusion is a regional treatment technique that delivers high dose chemotherapy, biologic agents, and hyperthermia via a completely isolated vascular recirculating perfusion circuit as a means of regionally treating tumors. The major artery leading into the limb, and the major vein returning blood from the limb, have their blood supply diverted to a "perfusion circuit" [like a heart lung machine]. The chemotherapy and other agent[s] are injected into the limb circulation, but do NOT get into the rest of the body's circulation. The limb's blood circulation is ISOLATED from the rest of the body. After perfusing the limb for an hour with the high concentration chemotherapy agent, the limb is given a 'washout' and then reconnected normally to the systemic circulation. This allows higher concentration of toxic chemicals to be given to the limb, and spares the rest of the body the exposure to the agent and the side effects. Side effects of Isolated Limb Perfusion include acute regional toxic reactions, lymphedema, muscle atrophy or fibrosis, limb malfunction, neuropathy, pain, recurrent infection. The majority had more than one side effect. "Acute regional toxic reactions had a statistically significant effect on the incidence of long-term morbidity ... Moderate to severe acute regional toxic reactions were strongly linked to the occurrence of muscle atrophy or fibrosis ... and limb malfunction ... Regional lymph node dissection was statistically significantly related to lymphedema ... Improvement of the perfusion technique should be pursued in an effort to reduce acute regional toxic reactions, and thereby long-term morbidity, without compromising the therapeutic effect. " Reference For general principles of isolated perfusion, see that section under Liver Metastases. Again, the best choice of therapy for LMS of the extremities is surgical excision with wide clear margins. This might mean amputation for some sites of LMS, but isolated limb perfusion can make limb salvage possible. Where surgical excision cannot be done, or where the LMS must be reduced in size to become resectable, isolated limb perfusion has some advantages for treatment.

Experimental approaches to treatment of soft tissue sarcoma. Hwang RF, Hunt KK. Department of Surgical Oncology, University of Texas M.D. Anderson Cancer Center, Houston, TX 77030, USA. The experimental approaches described in this article represent potential new approaches for targeted therapy. Thus far, none of the preclinical data have demonstrated a cure for sarcomas; however, the antitumor effects of many of these new agents seem to be enhanced when the agents are combined with chemotherapeutic agents. The combination of novel therapeutics with conventional chemotherapy may be the most effective strategy in terms of maximization of tumor killing and minimization of toxicity and the risk of drug resistance. Not only are new drugs being developed for treatment of sarcomas but new ways of delivering drugs are also being investigated. The angiogenic, or metronomic, schedule of drug delivery may be preferable to conventional schedules in achieving optimal tumor inhibition. In addition, isolated limb perfusion is a unique approach to delivery of drugs, such as TNF and melphalan, for sarcomas and melanomas ... The advantages of this method of drug delivery include the ability to administer therapeutic agents in high concentrations to a specific region of the body without systemic toxicity. ...

Department of Surgery, The Netherlands Cancer Institute/Antoni van Leeuwenhoek Hospital, Amsterdam, The Netherlands. ...Since 1992, isolated limb perfusion (ILP) with tumor necrosis factor-alpha (TNFalpha) and melphalan has been used for the treatment of patients with unresectable soft tissue sarcomas of the extremities. The authors retrospectively studied the results of limb salvage surgery using TNFalpha-ILP at their institution. ...: In 1 patient (2%) who died 2 days after undergoing ILP, response and acute limb toxicity could not be assessed. One patient (2%) attained a clinical complete response (2%), 23 patients (47%) attained a clinical partial response, 17 patients (35%) demonstrated no change, and 7 patients (14%) had tumor progression. Thirty-one patients (63%) underwent tumor resection....Final response, based on both clinical and pathologic assessment in which pathology was decisive, was complete in 4 patients (8%) and partial in 27 patients (55%), resulting in a final overall response rate of 63%. Local control with preservation of the limb was attained in 28 patients (57%). Four of 32 patients (13%) who had been rendered tumor free by ILP with or without undergoing resection and radiation therapy, developed a local recurrence. The 5-year disease specific survival rate was 48% for the 49 patients. Acute limb toxicity after ILP was a mild Grade 1-2 reaction in 35 patients (71%) patients, a Grade 3 reaction in 12 patients (25%), and a Grade 4 reaction in 1 patient (2%). Three major ILP-related complications were encountered, including arterial thrombosis in two patients and a fulminant Clostridial infection leading to death in one patient. There were no severe cardiovascular reactions after ILP. In patients with unresectable soft tissue sarcomas of the limbs who underwent ILP with TNFalpha and melphalan followed by resection of the tumor remnant when possible, a 63% overall tumor response rate and a 57% local control rate with limb preservation was achieved.

Hyperthermic isolated limb perfusion in the management of extremity sarcoma. Hoekstra HJ, van Ginkel RJ. Division of Surgical Oncology, Department of Surgery, Groningen University Hospital, PO Box 30.001, 9700 RB Groningen, The Netherlands. High local drug concentrations can be achieved in a limb with minimal systemic toxicity with the technique of hyperthermic isolated limb perfusion (HILP). The currently most successful drugs are still Tumor Necrosis Factor alpha (TNFalpha) and melphalan. With HILP, as an induction chemotherapy treatment of locally advanced primarily irresectable soft tissue sarcomas of a limb, a limb salvage rate of 71% can be achieved, with a minimal treatment related morbidity. For the HILP is no upper age limit. Systemic inflammatory response syndrome is currently seldom seen. The exact working mechanisms of TNFalpha are still unknown. Experimental work is now directed to the development of drugs sensitizing the tumor vasculature to the effects of TNFalpha. In the clinical HILP setting are currently lower doses of TNFalpha in combination with melphalan investigated. Although multidrug resistance (MDR) is a major issue in effectiveness of chemotherapy in human cancer treatment, HILPs with TNFalpha and melphalan did not induce MDR in sarcomas. The future research in HILP with TNFalpha is directed in increasing tumor sensitivity for TNF with lowering the dosage without decreasing tumor response.

Soft-tissue sarcomas are a group of rare malignant tumours, many of which arise in the limbs. Most are treated with a combination of wide local excision and radiotherapy, but a small number--including proximal, large, high-grade, or recurrent tumours, or those involving major neurovascular structures--necessitate major amputation including forequarter or hindquarter amputation. These uncommon operations should remain in the surgical armamentarium for carefully selected patients. Those being considered for amputation should be referred to a tertiary sarcoma unit for examination of all other options, such as limb-salvage surgery, tumour downstaging with chemotherapy or radiotherapy (perhaps with subsequent limb-salvage surgery), or novel techniques such as isolated limb perfusion. Only after careful assessment should amputation be carried out. Outcomes after major amputation are highly variable, but such procedures can confer useful palliation to patients with distressing symptoms (pain, bleeding, fungation), long-term disease-free survival with reasonable function in carefully selected patients, and cure in some.

Large medical centers, dealing with referrals and an important caseload of STS patients, should develop this treatment option and have it readily available to offer patients the best chances for limb salvage. In Europe, the success of TNF-based ILP has lead to the training, accreditation, and activation of TNF-based ILP programs in over 30 cancer centers since the approval of TNF for this indication in 1999. Thus, country by country centers for referral programs are established to deal with those categories of patients that can greatly benefit from the availability and integration of this treatment option in the STS treatment programs.

Important refinements have taken place in the diagnosis of soft tissue sarcoma with extensive use of immuno-histochemistry. New entities have been described, while malignant histiocytofibroma, the most diagnosed sarcoma type during the last two decades, has been dismembered. As for prognosis, the new UICC classification is effectively more discriminating in the definition of prognostic groups; but the usefullness of new biological or genetic markers remains to be assessed. Several breakthrough have taken place in the last years in the treatment of soft tissue sarcoma. Isolated limb perfusion with TNF, hyperthermia and melphalan have proven its efficacy, and is now an alternative to preoperative chemotherapy and/or radiotherapy for limb sparing treatment of the primary tumor site or to amputation. For systemic treatments, novel cytostatic drugs have been shown to be active in sarcomas, including ecteinascidine (ET743) and Glivec (STI571). This last drug has been shown to be remarkably active in c-kit+ stromal sarcoma of the gastro-intestinal tract. It can hopefully regarded as an example for targeted therapies, which may come with a better understanding of the molecular mechanisms triggered by the fundamental, specific genetic alterations shown in sarcoma.

Amputation is unavoidable in 10% of these patients despite aggressive conventional therapy. Limb preservation was the objective in this select group of candidates for amputation or mutilating surgery. ... During a 36-month period, 35 patients with high grade soft tissue sarcoma underwent 41 ILPs with high dose rTNF-alpha (3-4 mg) and melphalan (1-1.5 mg/kg). There were 21 males and 14 females. The mean age was 48 years (range, 14-80 years).

Twenty-one patients presented with recurrent and 14 with very extensive primary tumors. The tumors were located in the upper extremity in 8 patients and in the lower extremity in 27 patients. Twenty-five patients were candidates for amputation and 10 for extensive mutilating surgery. ILP was performed via the corresponding vessels proximal to the tumor. Six patients with partial response (PR) insufficient to render them resectable underwent a second ILP. With the exception of 4 of 9 patients with multifocal lesions and 1 who refused surgery, resection of the residual tumor or tumor bed or limb was performed 6-8 weeks after ILP. ...Marked tumor softening occurred within 48 hours, and in tumors protruding through the skin hemorrhagic necrosis was evident within 24 hours. The overall response rate was 91%. Thirteen patients (37%) had a complete response and 19 (54%) had a PR; in 5 of these patients > 90% necrosis of the tumor occurred.

"Soft-tissue sarcomas constitute a rare group of malignant tumours with histopathological features of connective, muscular, fatty or peripheral nervous tissue.

Consequently, tumours suspected of being soft-tissue sarcomas require multidisciplinary management from the beginning, with the team members familiar with each other's diagnostic and therapeutic skills.

The mean dose of radiation prescribed at the implant procedure was 47.2 Gy +/- 1.6 Gy (range, 11.0 to 50.0 Gy). A tissue transfer flap was placed over the bed of resection in 13 cases. Complications occurred in five patients including, three with wound breakdown, one with osteonecrosis, and with neuralgia. Operative intervention was required in four of the five patients with complications; ... Recurrence of disease occurred in 13 patients: nine local and four distant metastases. The median follow-up was 16 months (range, 2 to 73 months). The 5-year local recurrence-free, distant recurrence-free, disease-free, and overall survival rates after brachytherapy were 52%, 75%, 33%, and 52%, respectively. Re-irradiation of recurrent soft tissue sarcoma by brachytherapy in conjunction with resection can be performed with acceptable complication rates. Local control can be achieved for the majority of patients who would otherwise require more radical surgical procedures. Fetch PMID: 10188058 3: Radiother Oncol. 1996 Dec;41(3):209-14. Soft tissue sarcoma of the extremity. Limb salvage after failure of combined conservative therapy. Catton C, Davis A, Bell R, O'Sullivan B, Fornasier V, Wunder J, McLean M. University Musculoskeletal Oncology Unit, Princess Margaret Hospital, Toronto, Canada. PURPOSE: To assess the results of salvage therapy using surgery alone or surgery and re-irradiation for patients with locally recurrent extremity soft tissue sarcoma (STS) following conservative surgery and radiotherapy. ...25 patients with locally recurrent STS after conservative surgery and irradiation were assessed between 1990 and 1995. Two patients with concurrent systemic relapse were treated palliatively. Seven patients were not candidates for conservative re-excision and underwent amputation, 11 patients underwent conservative resection without irradiation. Seven of these patients relapsed, and five went on to receive combined conservative surgery and re-irradiation. A further five patients initially received combined retreatment, for a total of ten patients treated with combined conservative surgery and re-irradiation. Six of these ten patients were treated with brachytherapy alone, one with brachytherapy and external beam therapy, and three with external beam therapy alone. The median retreatment dose was 49.5 Gy (range 35-65 Gy), and the median cumulative soft tissue dose was 100 Gy (range 93-120 Gy). ... The median follow-up from the most recent treatment is 24 months (range 7-42 months). At the last follow-up 14 patients are alive and disease free; two are alive with local disease and four with systemic disease, and five are dead of disease. Overall local control is 19/23 (91%). The local control for patients treated with conservative excision without irradiation is 4/11 (36%) and for conservative excision with re-irradiation 10/10 (100%). Six (60%) of these patients experienced significant post-irradiation would-healing complications, but three have recovered fully. Functional scores for the entire treated group are significantly lower after treatment, as are those for patients undergoing combined surgery and re-irradiation, but 70% of those treated with conservative surgery and re-irradiation and a good or excellent post-treatment functional score. Combined conservative surgery and re-irradiation provided superior local control to local re-excision alone and a functional outcome superior to amputation. Combined treatment with re-irradiation should be considered the primary salvage therapy for patients who fail combined therapy and who are suitable for conservative re-excision. Systemic relapse is a significant problem, and optimal therapy should minimize the risk of local relapse after the initial therapy. Eighteen patients (72%) had a history of intralesional excision as their initial intervention, and suggests that inappropriate initial management is a risk factor for relapse after combined conservative therapy. Improvements in therapy must include the appropriate education of the primary care physicians. Fetch PMID: 9027935 4: Br J Radiol. 1992 Feb;65(770):157-61. Re-irradiation of soft-tissue sarcoma. Graham JD, Robinson MH, Harmer CL. Sarcoma Unit, Royal Marsden Hospital, London, UK. Re-irradiation for local recurrence of malignancy after radical radiotherapy is of proven benefit at head and neck sites but has seldom been used elsewhere. This paper reports a series of 10 patients re-irradiated with external-beam techniques for local recurrence of soft-tissue sarcoma of the limb and limb girdle following initial limb conserving management with surgery and radiotherapy (dose range 33-60 Gy). Median survival was 14 months following re-treatment. Two cases received treatment with high-energy electrons and the rest with megavoltage photons. Five patients re-treated with radical intent (dose range 40-60 Gy) had a median survival of 36 months and median recurrence-free survival of 16 months. All five patients treated palliatively (dose range 12-50 Gy) have died, although two demonstrated local control until death. Acute reactions were not severe. Radionecrosis was seen in one patient who was re-irradiated twice (total dose 145 Gy) and subsequently required amputation. One other case required amputation for persistent local disease, but in the remaining eight, limb conservation was achieved. Re-irradiation of soft-tissue offers good local control and may avoid amputation. Fetch PMID: 1371706 5: Int J Radiat Oncol Biol Phys. 1989 Sep;17(3):499-505. Aggressive management of second primary tumors in survivors of hereditary retinoblastoma. Smith LM, Donaldson SS, Egbert PR, Link MP, Bagshaw MA. Department of Radiation Oncology, Stanford University Medical Center, CA 94305. Survivors of hereditary retinoblastoma are at increased risk for the development of second primary tumors, most commonly osteosarcoma. Recent molecular genetic data demonstrate that a pleiotrophic effect of the retinoblastoma gene may be responsible for the development of these sarcomas. This report describes the incidence of second nonocular malignancies among 53 infants seen at Stanford University Medical Center who have been followed a median of 11.7 years. Of these, 42 initially had bilateral disease and eleven had unilateral disease. Of 53 infants, 50 received irradiation either as part of the initial therapy or as treatment for recurrent disease. The actuarial survival for the entire group is 67% at 30 year follow-up with a median survival of 79% at 11.7 years. Eight patients developed eleven second primary tumors. All occurred in the group having hereditary retinoblastoma. Eight were within the previously irradiated field and three were at distant sites. The second tumors included seven osteosarcomas, one angiosarcoma, one rhabdomyosarcoma, one malignant fibrous histiocytoma, and one unclassifiable round blue cell tumor. The actuarial incidence of the development of a second primary malignancy was 6% at 10 years, 19% at 20 years, and 38% at 30 years. The latent period from treatment of retinoblastoma to the diagnosis of malignancy ranged from 5.2 years to 36.2 years (median 16 years). An aggressive approach with combined modality therapy including radical resection, re-irradiation and/or chemotherapy was used to treat these second primary tumors in five of eight patients. In four of the five, there was no evidence of disease at 22-72 months following treatment. In the three patients who did not receive aggressive combined treatment, there were no survivors. These data confirm the previously reported risk of developing a second primary tumor among survivors with hereditary retinoblastoma. Careful long-term follow-up for this genetically susceptible group is essential for early detection and implementation of curative therapy.

Midwest Institute for Neutron Therapy at Fermilab, Batavia, IL 60510. Forty-six patients with locally recurrent disease were re-irradiated with fast neutrons at Fermilab. All had received prior radical radiation therapy either with or without surgery. Six were palliative. Forty patients treated with curative intent were analyzed for local response, survival, and complications. The overall response rate was 78% (31/40); 50% (20/40) had a complete local response. Ten of 16 patients (63%) with non-epidermoid carcinomas in the head and neck regions had complete response, whereas only nine of twenty patients (45%) with epidermoid carcinomas were complete responders. In a subset of 12 patients with salivary gland type tumors, 10 had a complete response (83%). Two of these 10 patients are alive beyond 5 years. Observed median survival for the forty patients was 9.3 months, and for complete responders 14.4 months. Observed median survival for partial responders was only 7.5 months. Four of six patients treated for palliation had significant subjective improvement. Significant morbidity, Grade III or greater (EORTC/RTOG scale), was seen in only 10 patients (25%), and this was found to depend directly on the total dose delivered. We conclude that neutron beam therapy can be used as a therapeutic modality for patients with recurrent tumors with an acceptable degree of morbidity. Fetch PMID: 3391808 |
