(Refer to the PDQ summary on Levels of Evidence for more information.)

Soft tissue sarcomas are malignant tumors that may arise in any of the mesodermal tissues of the extremities (50%), trunk and retroperitoneum (40%), or head and neck (10%). Rarely, these tumors arise in the gastrointestinal tract or gastrointestinal stroma, and a small percentage of these are called gastrointestinal stromal tumors (GISTs). Malignant GISTs can occur from the esophagus to the rectum but occur most commonly in the stomach and small intestine. Soft tissue sarcomas occur with greater frequency in patients with:2,

  • von Recklinghausen’s disease (neurofibromatosis).
  • Gardner’s syndrome.
  • Werner’s syndrome.
  • Tuberous sclerosis.
  • Basal cell nevus syndrome.
  • Li-Fraumeni syndrome (p53 mutations).

Soft tissue sarcomas may be heterogeneous, so adequate tissue should be obtained via either core-needle or incisional biopsy for microscopic examination to determine histologic type and tumor grade. Careful planning of the initial biopsy is important to avoid compromising subsequent curative resection. Since the selection of treatment is determined by the grade of the tumor, it is essential to have a careful review of the biopsy tissue by a pathologist who is experienced in diagnosing sarcomas. Complete staging and treatment planning by a multidisciplinary team of cancer specialists is required to determine the optimal treatment for patients with this disease. In most cases, a combined modality approach of preoperative or postoperative radiation therapy is used, rather than the radical surgical procedures that were used in the past. The role of chemotherapy is less well defined. Because of the evolving nature of the state of the art in the treatment of this disease, all patients with such lesions should be included in a clinical trial whenever possible.

The prognosis for patients with adult soft tissue sarcomas depends on several factors, including the patient’s age and the size, histologic grade, and stage of the tumor.3,4,5 Factors associated with a poorer prognosis include age older than 60 years, tumors larger than 5 cm, or high-grade histology.6,

While low-grade tumors are usually curable by surgery alone, higher-grade sarcomas (as determined by the mitotic index and by the presence of hemorrhage and necrosis) are associated with higher local treatment failure rates and increased metastatic potential.7 When feasible, wide margin function-sparing surgical excision is the cornerstone of effective treatment, with the goal of preservation of a functional extremity.8,9 This may be facilitated by soft tissue reconstructive surgery.10 Mohs surgical technique may be considered as an alternative to wide surgical excision for small, well-differentiated sarcomas when cosmetic results are considered to be very important, as margins can be assured with minimal normal tissue removal.2,11 High-grade soft tissue sarcomas of the extremities can often be effectively treated while preserving the limb with combined-modality treatment consisting of preoperative or postoperative radiation therapy to reduce local recurrence.8,12,13,14,15,16,17,18,19,20 In adults, local control of high-grade soft tissue sarcomas of the trunk and the head and neck can be achieved with surgery, often in combination with radiation therapy with or without chemotherapy.21,

Effective treatment of retroperitoneal sarcomas requires removal of all gross disease while sparing adjacent viscera not invaded by tumor. The prognosis for patients with high-grade retroperitoneal sarcomas is less favorable than for patients with tumors at other sites, partly because of the difficulty in completely resecting these tumors and the limitations placed on high-dose radiation therapy.2,22 Surgical resection is the most effective treatment modality for GISTs.23 Evidence indicates that imatinib mesylate, a tyrosine kinase inhibitor, induced sustained tumor response in patients with unresectable or metastatic GIST tumors.24,25,26,[Level of evidence: 3iiiDiii]27,28,

Several prospective randomized trials have been unable to confirm conclusively whether doxorubicin-based adjuvant chemotherapy benefits adults with resectable soft tissue sarcomas. The majority of these studies accrued small numbers of patients and did not demonstrate a metastasis-free survival or an overall survival (OS) benefit for adjuvant chemotherapy.21 A small study of adjuvant chemotherapy showed a positive impact in disease-free survival and OS in patients treated with postoperative chemotherapy.29 There was wide interstudy variability among the numerous trials, including differences in therapeutic regimens, drug doses, sample size, tumor site, and histologic grade. A quantitative meta-analysis of updated data from 1,568 individual patients from 14 trials of doxorubicin-based adjuvant therapy showed an absolute benefit from adjuvant therapy of 6% for local relapse-free interval (95% confidence interval [CI], 1–10), 10% for distant relapse-free interval (95% CI, 5–15), and 10% for recurrence-free survival (95% CI, 5–15); however, there was no OS benefit at 10 years.30,[Level of evidence: 1iiDi] Patients with high-grade tumors (grades 3 or 4) larger than 5 cm in diameter have the greatest tendency for disease to metastasize and are eligible for prospective clinical trials of adjuvant chemotherapy.

With distant metastases (stage IV), surgery with curative intent is possible for patients selected for optimal underlying biologic behavior (i.e., patients with a limited number of metastases, with a long disease-free interval, and with slow clinical growth) with pulmonary metastases who have undergone or are undergoing complete resection of the primary tumor.31,32,33 Doxorubicin alone or with dacarbazine is considered the best chemotherapeutic regimen for advanced sarcoma.34,35,36 A randomized trial of 340 patients with advanced sarcoma showed a higher response rate (32% vs. 17%, P < .002) and longer time-to-progression (6 vs. 4 months, P < .02) for doxorubicin, dacarbazine, ifosfamide, and mesna (MAID) versus doxorubicin and dacarbazine alone.37,[Level of evidence: 1iiDii] The increased response rate of the MAID regimen may be justified in preoperative management of younger patients with borderline resectability, but the increased toxic effects argue against its use in older patients.37,

Complete surgical resection is often difficult for sarcomas of the retroperitoneum because of their large size before detection and anatomic location.38,39 Prospective randomized trials have not shown improved survival with preoperative or postoperative adjuvant chemotherapy for this subgroup.30,

Cellular Classification

Soft tissue sarcomas are classified histologically according to the soft tissue cell of origin, though the cell type is not part of the prognostic staging system. Additional studies, including electron microscopy, histochemistry, flow cytometry, cytogenetics, and tissue culture studies may allow identification of particular subtypes within the major histologic categories. The histologic grade reflects the metastatic potential of these tumors more accurately than the classic cellular classification listed below.1,2,3 Overall, malignant fibrous histiocytoma is the most common histologic type (40% of the total) followed by liposarcoma (25%); however, frequency of histologic type is site-dependent. Pathologists assign grade based on the number of mitoses per high-powered field, presence of necrosis, cellular and nuclear morphology, and the degree of cellularity; discordance among expert pathologists can reach 40% on prospective review.3,4,

Soft tissue sarcomas include the following tumors:

  • Alveolar soft-part sarcoma.5,
  • Angiosarcoma.6,
  • Dermatofibrosarcoma protuberans.7,
  • Epithelioid sarcoma.
  • Extraskeletal chondrosarcoma.
  • Extraskeletal osteosarcoma.
  • Fibrosarcoma.
  • Gastrointestinal stromal tumor (GIST).
  • Leiomyosarcoma.
  • Liposarcoma.
  • Malignant fibrous histiocytoma.
  • Malignant hemangiopericytoma.
  • Malignant mesenchymoma.
  • Malignant schwannoma.
  • Malignant peripheral nerve sheath tumor.
  • Peripheral neuroectodermal tumors.
  • Rhabdomyosarcoma.
  • Synovial sarcoma.
  • Sarcoma, NOS (not otherwise specified).

GISTs are mesenchymal in origin and are immunohistochemically distinct from leiomyosarcomas, schwannomas, and fibrosarcomas with which they are often classified. They can be distinguished by being CD34 positive and CD117 positive. These tumors express a growth factor receptor with tyrosine kinase activity called c-kit (CD117). GISTs of the stomach wall are considered malignant when they exceed 5 to 10 cm, have a high mitotic index, or have metastasized. GISTs of the small bowel are considered malignant if they have any mitoses or are larger than 2 cm. Current evidence suggests that c-kit mutations are more commonly identified in malignant GISTs than in benign GISTs. Malignant GISTs are also usually CD34 positive.8,9,10,11,

Stage Information

Staging has an important role in determining the most effective treatment of soft tissue sarcomas. The stage is determined by the size of the tumor, the histologic grade, and whether it has spread to lymph nodes or distant sites. Intracompartmental or extracompartmental extension of extremity sarcomas is also important for surgical decision making. For complete staging, a thorough physical examination, x-rays, laboratory studies, and careful review of all biopsy specimens (including those from the primary tumor, lymph nodes, or other suspicious lesions) are essential. Computed tomographic scan of the chest is recommended for sarcomas larger than 5 cm (T2) or with moderate to poor differentiation (grades 2–4). Nodal involvement is rare, occurring in less than 3% of patients with sarcoma.1,

The American Joint Committee on Cancer (AJCC) has designated staging by the four criteria of tumor size, nodal status, grade, and metastasis (TNGM).2,

Grade and TNM Definitions

    Tumor grade (G)
  • GX: Grade cannot be assessed
  • G1: Well differentiated
  • G2: Moderately differentiated
  • G3: Poorly differentiated
  • G4: Poorly differentiated or undifferentiated
    Primary tumor (T)
  • TX: Primary tumor cannot be assessed
  • T0: No evidence of primary tumor
  • T1: Tumor 5 cm or less in greatest dimension
    • T1a: Superficial tumor
    • T1b: Deep tumor
  • T2: Tumor 5 cm or larger in greatest dimension
    • T2a: Superficial tumor
    • T2b: Deep tumor

Superficial tumor is located exclusively above the superficial fascia without invasion of the fascia; deep tumor is located either exclusively beneath the superficial fascia, or superficial to the fascia with invasion of or through the fascia, or both superficial yet beneath the fascia. Retroperitoneal, mediastinal, and pelvic sarcomas are classified as deep tumors.

    Regional lymph nodes (N)
  • NX: Regional lymph nodes cannot be assessed
  • N0: No regional lymph node metastasis
  • N1: Regional lymph node metastasis Presence of positive nodes (N1) is considered stage IV.
    Distant metastasis (M)
  • MX: Distant metastasis cannot be assessed
  • M0: No distant metastasis
  • M1: Distant metastasis

Treatment Option Overview

The designations in PDQ that treatments are “standard” or “under clinical evaluation” are not to be used as a basis for reimbursement determinations.

Stage I Adult Soft Tissue Sarcoma

Low-grade soft tissue sarcomas (grade 1 or 2) have little metastatic potential, but they may recur locally if they are inadequately treated. Accordingly, surgical excision with negative tissue margins of 2 cm or larger in all directions is the treatment of choice for patients with these early-stage sarcomas.1 Mohs surgical technique may be considered as an alternative to wide surgical excision for small, well-differentiated sarcomas when cosmetic results are considered to be very important, as margins can be assured with minimal normal tissue removal.2,3,

Carefully executed high-dose radiation therapy using a shrinking field technique may be beneficial for unresectable tumors or for resectable tumors in which a high likelihood of residual disease is thought to be present, when margins are known to be smaller than 2 cm, and when wider resection would require either an amputation or the removal of a vital organ.4 Because of the low metastatic potential of these tumors, chemotherapy is usually not given.5

Standard treatment options:

  1. Surgical excision with negative tissue margins of several centimeters in all directions.
  2. Conservative surgical excision with preoperative or postoperative radiation therapy.6,7,
  3. If the tumor is unresectable, high-dose preoperative radiation therapy may be used, followed by surgical resection and postoperative radiation therapy.4,8,
  4. For tumors of the retroperitoneum, trunk, and head and neck:
    • Surgical resection with the option of postoperative radiation therapy if negative margins cannot be obtained. Wide margins are unusual in these sites, and radiation therapy is usually advocated for trunk and head and neck primary sites.3,
    • Preoperative radiation therapy followed by maximal surgical resection. Radiation therapy is usually used to maximize local control because of the inability to obtain wide surgical margins.
    • Fast neutron therapy.9,

Stage II and III Adult Soft Tissue Sarcoma

Note: Some citations in the text of this section are followed by a level of evidence. The PDQ editorial boards use a formal ranking system to help the reader judge the strength of evidence linked to the reported results of a therapeutic strategy. (Refer to the PDQ summary on Levels of Evidence for more information.)

High-grade localized soft tissue sarcomas have an increased potential for metastatic spread. For sarcomas of the extremities, local control comparable to that obtained with amputation may be achieved with limb-sparing surgery that involves wide local excision in combination with preoperative or postoperative radiation therapy and in some instances, chemotherapy.1,2,3,4,

Several prospective randomized trials have been unable to confirm conclusively whether doxorubicin-based adjuvant chemotherapy benefits adults with resectable soft tissue sarcomas. The majority of these studies accrued small numbers of patients and did not demonstrate a metastasis-free survival or an overall survival (OS) benefit for adjuvant chemotherapy.5 Interstudy variability was wide among the numerous trials, including differences in therapeutic regimens, drug doses, sample size, tumor site, and histologic grade. A quantitative meta-analysis of updated data from 1,568 individual patients from 14 trials of doxorubicin-based adjuvant therapy showed an absolute benefit from adjuvant therapy of 6% for local relapse-free interval (95% confidence interval [CI], 1–10), 10% for distant relapse-free interval (95% CI, 5–15), and 10% for recurrence-free survival (95% CI, 5–15); however, there was no OS benefit at 10 years.6,[Level of evidence: 1iiDi] Patients with high-grade tumors (grades 3 or 4) larger than 5 cm in diameter have the greatest tendency for disease to metastasize and are eligible for prospective clinical trials of adjuvant chemotherapy.

Complete surgical resection is often difficult for sarcomas of the retroperitoneum because of their large size before detection and anatomical location.7,8 As opposed to soft tissue sarcomas of the extremities, local recurrence is the most common cause of death in patients with retroperitoneal soft tissue sarcomas. Complete surgical resection (i.e., removal of all gross tumor) is the most important factor in preventing local recurrence and, in many instances, requires resection of adjacent viscera. The role of adjuvant radiation therapy in the treatment of patients with retroperitoneal sarcoma has not been clearly defined. Prospective randomized trials have not shown improved survival with preoperative or adjuvant chemotherapy for this subgroup.6,9,

Standard treatment options:

  1. Surgical excision with negative tissue margins of several centimeters in all directions may be used.
  2. If the tumor is greater than 5 cm in diameter, surgical excision with negative tissue margins of several centimeters in all directions followed by radiation therapy may be used.
  3. If the tumor is unresectable, high-dose radiation therapy may be used, but poor local control is likely to result.
  4. In some situations, radiation therapy or chemotherapy may be used prior to surgery to convert a marginally resectable tumor to one that can be adequately resected with limb preservation; this treatment may be followed by postoperative radiation therapy.

Stage IV Adult Soft Tissue Sarcoma

Note: Some citations in the text of this section are followed by a level of evidence. The PDQ editorial boards use a formal ranking system to help the reader judge the strength of evidence linked to the reported results of a therapeutic strategy. (Refer to the PDQ summary on Levels of Evidence for more information.)

Nodal Disease

Stage IV sarcomas are tumors that have metastatic involvement of regional lymph nodes or have spread to distant organs. Soft tissue sarcomas that more commonly spread to lymph nodes include synovial cell sarcomas, epithelioid sarcomas, and rhabdomyosarcomas. For stage IV sarcomas, local control of the primary tumor is probably best obtained by resection with negative margins, lymphadenectomy when appropriate, and postoperative external-beam radiation therapy.1 For gastrointestinal stromal tumors (GISTs), preliminary evidence indicates that imatinib mesylate, a tyrosine kinase inhibitor, induced sustained tumor response in patients with unresectable or metastatic tumors.2,3,4,5,[Level of evidence: 3iiiDiii]

Standard treatment options:

  1. Surgical resection and lymphadenectomy for patients with clinically positive lymph nodes with or without postoperative radiation to the primary site may be used.
  2. In some centers, radiation therapy may be used prior to and following surgical extirpation.6,
  3. Adjuvant chemotherapy may be considered for patients eligible for clinical trials.7,8,9,10,

Visceral Disease

With distant metastases, surgery with curative intent is possible for patients with limited pulmonary metastases who are also undergoing or have undergone complete resection of the primary tumor.11,12,13 The role of adjuvant therapy for pulmonary nodules is under clinical evaluation.14 The value of resection of hepatic metastases is unclear. Doxorubicin alone or with dacarbazine is considered one of the most frequently used chemotherapeutic regimens for advanced sarcoma.15,16,17 When used as single agents, only doxorubicin and ifosfamide show >20% response rates; less active drugs include dacarbazine, cisplatin, methotrexate, and vinorelbine.18 A randomized trial of 340 patients with advanced sarcoma showed a higher response rate (32% vs. 17%, P < .002) and longer time-to-progression (6 vs. 4 months, P < .02) for doxorubicin, dacarbazine, ifosfamide, and mesna versus doxorubicin and dacarbazine alone.19,[Level of evidence: 1iiDii] For older patients, sequential use of single agents with each recurrence is a better strategy for palliation. High-dose chemotherapy (with or without transplantation) has not influenced disease-free survival or overall survival in published studies so far, but it remains under clinical evaluation for patients with metastatic disease in first complete remission, after resection of pulmonary nodules, or for inoperable large primaries.20 For GISTs, preliminary evidence indicates that imatinib mesylate, a tyrosine kinase inhibitor, induced sustained tumor response in patients with unresectable or metastatic tumors.2,3,4,[Level of evidence: 3iiiDiii]

Standard treatment options:

  1. Surgical resection of the primary tumor with radiation therapy. Resection of pulmonary lesions may be performed following definitive therapy of the primary tumor.11,12,13,
    • Surgical excision with negative tissue margins may be used.
    • If the tumor is resectable but wide margins cannot be obtained, radiation therapy may be added.
    • If the tumor is unresectable, high-dose radiation therapy may be used, often with chemotherapy.
    • For tumors of the retroperitoneum, trunk, and head and neck, surgical resection with preoperative and/or postoperative radiation therapy, and sometimes chemotherapy, may be used.
  2. For palliation of patients with unresectable visceral disease, chemotherapy with the following agents may be used:
    • Doxorubicin.15,
    • Doxorubicin + dacarbazine.15,16,
    • Doxorubicin + ifosfamide.21,
    • Doxorubicin + dacarbazine + ifosfamide + mesna.19,22,
    • High-dose ifosfamide regimens.23,24,25,

Recurrent Adult Soft Tissue Sarcoma

Note: Some citations in the text of this section are followed by a level of evidence. The PDQ editorial boards use a formal ranking system to help the reader judge the strength of evidence linked to the reported results of a therapeutic strategy. (Refer to the PDQ summary on Levels of Evidence for more information.)

Treatment of recurrent soft tissue sarcomas depends on the type of initial presentation and treatment. Patients who develop a local recurrence often can only be salvaged by aggressive local therapy: local excision plus radiation therapy after previous minimal therapy or amputation after previous aggressive treatment.1,2 For selected patients who received radiation therapy, preoperative radiation therapy and wide local excision may avoid the need for amputation.3,4,5 Metastases to the lung as first recurrence usually occur within 2 to 3 years of initial diagnosis and should be treated as described under treatment for stage IV disease.6,7,8 A 30% survival rate at 3 years is noted if limited pulmonary metastases are resectable.

Doxorubicin alone or with dacarbazine is one of the most frequently used chemotherapeutic regimens for advanced sarcoma.9,10,11 When used as single agents, only doxorubicin and ifosfamide show response rates greater than 20%; less active drugs include dacarbazine, cisplatin, methotrexate, and vinorelbine.12 In a small study, pegylated liposomal doxorubicin has shown similar activity to doxorubicin, with fewer toxic effects.13,[Level of evidence: 3iiiDiii] A randomized trial of 340 patients with advanced sarcoma showed a higher response rate (32% vs. 17%, P < .002) and longer time-to-progression (6 vs. 4 months, P < .02) for doxorubicin, dacarbazine, ifosfamide, and mesna versus doxorubicin and dacarbazine alone.14,[Level of evidence: 1iiDii] Sequential use of doxorubicin followed by ifosfamide or other drugs with each subsequent recurrence is frequently preferred. Clinical trials of phase I and II agents should be considered for subsequent recurrences. High-dose chemotherapy (with or without transplantation) has not influenced disease-free survival or overall survival in published studies, but it remains under clinical evaluation for patients with metastatic disease in first complete remission, after resection of pulmonary metastases, or for inoperable large primaries.15,16,17 Information about ongoing clinical trials is available from the NCI Web site.
