Abstract
Sarcomas are malignant mesenchymal tumours. They are relatively uncommon in the head and neck region. They are diverse affecting both soft and hard tissues. Multiple histological subtypes are recognised. There is considerable variation in their behaviour and response to treatment, both in adults and children. Historically, poor outcomes are due to multiple reasons such as paucity of standardised treatment approaches and the complex anatomy of the head and neck region. Nevertheless, surgery plays a key part in the management of sarcomas, both from an ablative and reconstructive viewpoint. The modern reconstructive techniques have improved quality of life for those undergoing surgical ablation.

1 Introduction
Sarcomas are uncommon malignant tumours with incidence of less than 5% of all head and neck malignancies in adults [1, 2]. They are more common in children, accounting for 30% of head and neck sarcomas [2, 3]. They arise from either soft or hard tissue mesenchyme cells. There is a male predominance and presentation is usually in the third and fourth decade of life in 70% of cases [4, 5].
Metastasis at initial presentation is seen in only 10% of patients, usually from high-grade primary lesions [6,7,8]. Despite this, prognosis tends to be poor, partly due to the proximity of vital neurovascular structures leading to difficulty in obtaining adequate surgical clearance. Moreover, majority of the sarcomas are poorly differentiated, a poor prognostic marker [9].
Sarcomas tend not be related to the use of tobacco and alcohol. Predisposition to the development of sarcomas is seen in some conditions [4, 8, 10]. Notable examples include association of osteosarcoma in patients with Li-Fraumeni syndrome, angiosarcoma with chronic lymphoedema and Kaposi’s sarcoma with HIV infection. Additionally, exposure to chemicals such as vinyl chloride is well-recognised risk factors [10].
2 Classification
Broadly speaking, sarcomas can be classified into two categories: soft tissue and hard tissue (bone and cartilage) sarcomas. This, however, is an oversimplification since precise classification is fraught with significant difficulties. For example, fibrosarcoma and malignant fibrous histiocytoma are soft tissue sarcomas that arise in hard tissues [11, 12]. In contrast, chondrosarcomas are classified as soft tissue tumours. Additionally, some hard tissue tumours display extraosseous extension [1,2,3].
Ten or more main histological types and even more subtypes of sarcomas are described. Osteosarcoma, angiosarcoma and malignant fibrous histiocytoma make up the majority tumours in adults. In children, rhabdomyosarcoma is the most common sarcoma [1,2,3].
3 Staging
Soft and hard tissue sarcomas are staged using different systems (Tables 83.1 and 83.2). The American Joint Committee on Cancer (AJCC) and the International Union Against Cancer (UICC) staging systems are used in most centres [13]. Other systems may be used in selected cases such as the Memorial Sloan Kettering system [14].
4 Natural History and Prognostic Factors
Head and neck sarcomas tend to show poorer response to treatment compared to sarcomas affecting the trunk and extremities [5, 6]. This is despite the low rate of lymph node metastasis at presentation (less than 10% of cases) and the modern multimodality treatment with surgery, radiotherapy and chemotherapy [4, 5]. Local and regional nodal recurrence is common and is more likely to result in death than distant metastatic spread [5, 8, 10].
The reasons for treatment failure resulting in disease recurrence are multifactorial. Adequate surgical margins are hard to achieve given the complex anatomy of the maxillofacial and the skull base regions (Fig. 83.1). The morbidity of radical resections is unacceptable, both functional and aesthetic. This is especially true for primary tumour larger than 10 cm at presentation [8, 9, 11]. Resections aimed at minimising morbidity risk positive or involved surgical margins and are an independent predictor of treatment failure and hence survival [5, 7, 8]. The grade of tumour is another prognostic factor. For example, the 5-year survival rates for high-grade tumours such as malignant fibrous histiocytoma, osteosarcoma and angiosarcoma are in the range of 60%. This is in contrast with low-grade tumours such as chondrosarcoma or dermatofibrosarcoma protuberance which show survival approaching 100% at 5Â years [8, 9, 15]. There is optimism, however, with modern combined treatment modalities, for example, patients with rhabdomyosarcomas are showing better survival outcomes. Finally, sarcomas arising in previously irradiate tissues have poor prognosis due to a multitude of factors: delayed diagnosis; high-grade, inadequate surgical margins; limited option of adjuvant radiotherapy; and lack of proven chemotherapy regimens [10, 16, 17].
It is important to interpret the published treatment outcomes and survival rates with caution. Comparison between institutions is unreliable due to different study population, histological subtypes and follow-up regiments. Moreover, lack of standardisation in reporting leads to institutional bias of a selected treatment modality. Reported overall survival for bone sarcomas approach 80% at 2Â years and 74% at 5Â years [18, 19]. Radiation-induced sarcomas perhaps have the worse survival outcomes, as low as 25% at 5Â years [19, 20].
5 Principles of Treatment
It is difficult to draw firm treatment guidelines for head and neck sarcomas because they are a rare group of heterogeneous tumours. The treatment philosophies vary between institutions due to multitude of factors as discussed previously in this chapter. Meta-analysis outcomes are therefore controversial and unreliable to draw firm conclusions. Furthermore, there are no randomised controlled trials [20, 21]. Despite this, there is consensus that early surgical resection with appropriately timed adjuvant therapies can help improve outcomes. Needless to say, the role of multidisciplinary input/tumour board is vital.
Surgical resection of the tumour is the favoured primary treatment modality for patients with sarcomas of the hard tissues [22, 23]. Surgery is often preceded by chemotherapy on a neoadjuvant protocol [19, 22, 23]. The intention is to reduce tumour bulk and hence morbidity by minimising tissue loss. Elimination of micro-metastatic disease, mainly pulmonary deposits, is of added benefit. The role of adjuvant radiotherapy is limited to patients with positive surgical margins who often are not candidates for further resection [19, 24]. Further resections may not be feasible due to anatomical complexity or in those who have undergone complex reconstruction. Note should be made of the evolving role of radiotherapy in Ewing’s sarcoma.
The size of the tumour at presentation often restricts the use of surgery in patient presenting with soft tissue sarcoma. Adjuvant radiotherapy is an indication when the resection margins are positive; the tumours are of intermediate or high grade and in cases of recurrent disease [12, 16, 24, 25]. The feasibility of introducing neoadjuvant chemotherapy or preoperative radiotherapy should be considered with diligence in patients with advanced disease at presentation with a view to reduce morbid resections [25, 26]. When surgery is not feasible, the role of palliative radiotherapy alone or in combination with chemotherapy should be considered.
6 Principles of Surgery
6.1 Hard Tissue Sarcomas
There is a consensus that achieving tumour-free zone of tissue at the resection margins maximises the chance of cure. However, what defines adequate margin remains debated. The current recommendation is resection of the tumour with a 2–3 cm macroscopic margin in patients who receive neoadjuvant chemotherapy aiming to sterilise the microscopic deposits around the main body of the tumour [24,25,26,27,28]. It is important to plan the resection on scans obtained prior to the neoadjuvant chemotherapy. This is because both the tumour-killing effect of the neoadjuvant chemotherapy and tissue shrinkage are unpredictable. Furthermore, one should aim for compartmental excision (Fig. 83.1) that allows for removal of all potentially involved structures beyond the radiographic margins such as intra-osseous extension of the tumour via marrow spaces [2, 19, 24]. Although this approach is radical, for instance, resection of the hemi-mandible to include disarticulation of the condyle in ramus tumours, the chance of surgical clearance can be maximised to 85% or greater [2].
6.2 Soft Tissue Sarcomas
Similar to hard tissue sarcomas, adequate surgical margins predict survival outcomes, both disease-free and overall survival. The recommendation is for 1–3 cm macroscopic margins [24, 29, 30]. Achieving this may be limited due to anatomical constrains and an infiltrative pattern of tumour spread that tends to characterise soft tissue sarcomas. One published series reported adequate surgical clearance in 85% of osteosarcomas vs. 64% soft tissue tumours [2]. The 2-year overall survival estimate for bone tumours (51 patients) was 91% vs. 67% for soft tissue tumours (50 patients) [2]. The 5-year overall survival estimates were 73 and 56%, respectively. These results were statistically significant. Other series with different patient cohort have reported 5-year overall survival rates of 74 vs. 57% for bone and soft tissue sarcomas, respectively [31, 32].
7 Clinical Assessment
Patients present with a wide range of signs and symptoms. These may range from indolent lumps to rapidly growing and locally destructive lesions (Figs. 83.1 and 83.2). Pain is variable and there is a tendency for nocturnal bone pain [1, 4].
There may be a mass at the primary site, ulceration, sensory change affecting the skin or the mucosa, proptosis, epistaxis or nasal discharge, loosening of teeth and unexplained bleeding.
Involvement of the skull base by direct extension can lead to focal neurology. Metastatic lesions can present with a neck mass. Systemic symptoms tend to be non-specific such as malaise, loss of weight and appetite [8, 23].
8 Investigations
Magnetic resonance imaging (MRI) is usually the preferred investigation for primary lesions [30, 33]. They provide information regarding the nature of the primary tumour (solid, cystic, presence or absence of calcifications, internal vascularity, etc.). The relationship of the tumour to adjacent tissues can be accurately defined; this helps plan tumour resection [22, 34, 35]. Computer tomography (CT) scan of the facial bone may be used to complement the MRI scan, especially in patients requiring hard tissue resection and reconstruction (Figs. 83.1 and 83.2). The use of composite flaps with 3-D reconstruction with prefabricated plates is increasingly used in several centres [36, 37]. The use of dental implants has significantly improved outcomes following composite reconstructions (Fig. 83.2). CT scans of the thorax and upper abdomen complete the staging investigations. There is an evolving role for positron emission tomography (PET), both in the initial staging of the disease, the response to treatment and tumour surveillance [38, 39]. Blood tests include comprehensive baseline tests (full blood count, renal and bone profile) and serum alkaline phosphatase. Additional tests may be necessary, often dictated by individual patient profiles. Biopsy for tissue diagnosis must include an appropriate sample that in addition to routing staining provides tissue for immunocytochemistry [4, 12].
9 Osteosarcoma
Osteosarcomas are the commonest sarcomas of the bones in adults, representing 1% of all head and neck cancers. They do not show sex predilection. The peak incidence is between 20 and 30 years. However, tumours arising in area of Paget’s disease of the bone are seen in older patient 60–70 years of age [25,26,27]. The mandible is the most frequently affected site, especially the angle/ramus region. In the maxilla, the tumour has a predilection to the alveolar ridge and sinus floor. Notable risk factors include chromosomal abnormalities (deletion of 13q14), germ line mutations (Li Fraumeni syndrome) and dysplasia of bone (Paget’s disease and fibrous dysplasia) [25,26,27,28]. In some instances, these tumours arise in irradiated bone or de novo.
Patient may present with asymptomatic intra-oral mass, loose teeth and toothache.
Destructive lesions can cause soft tissue cheek swelling, sensory change, proptosis, nasal discharge or bleeding.
Three histological subtypes of osteosarcoma are recognised, namely, osteoblastic, chondroblastic and fibroblastic variants [31, 39].
However, myxoid pattern is the norm (Fig. 83.3). The chondroblastic variant shows binucleated cell characteristic of the lesion (Fig. 83.4) The degree of differentiation classifies them as stage I (well-differentiated and low-grade) to stage IV (poorly differentiated and high-grade). Regional neck metastases at presentation are rare, seen in less than 10% of patients at presentation. Distant metastases are seen in up to 30% of patients at presentation, mostly pulmonary [23, 27, 31]. On rare occasions, patients may present with rapidly progressive, fatal multifocal disease. Imaging reveals local bone. The well-documented finding of subperiosteal bone formation (Codman triangle) is uncommonly seen in head and neck lesions.
Whilst surgery, radiotherapy and chemotherapy are offered as single or multimodality treatments, well-established treatment regimens are lacking in consensus. Various drug combinations have been tried and tested, leucovorin, Adriamycin, cisplatin, ifosfamide and cyclophosphamide, with unpredictable response. One study has shown 2- and 5-year overall survival rates of 100 and 67%, respectively, in those treated with neoadjuvant chemotherapy and surgery. This compares favourably with patient treated with surgery alone showing poorer 2- and 5-year overall survival rates of 66 and 41%, respectively [19, 23, 31]. The role of adjuvant radiotherapy is applicable in patients with inadequate or positive surgical margins; however, doses in excess of 60Gy are necessary given their radio-resistant behaviours [8, 16, 31].
In addition to high-grade disease and large tumours at presentation, some additional factors have prognostic significance. For example, the expression of the p-glycoprotein confers multidrug resistance negatively impacting on prognosis. Osteosarcomas arising in Paget’s disease and elevated alkaline phosphate levels have poorer prognosis [9, 25, 27, 32].
10 Malignant Fibrous Histiocytoma
Malignant fibrous histiocytoma is the commonest soft tissue sarcoma affecting the trunks and extremities. However, it is rare in the head and neck region, with less than 3% occurring here. It shows a male predilection with a 2:1 ratio and mostly seen between 40 and 60Â years of age. The commonest subsite is the sinonasal tract. There is a strong link to ionising radiation exposure [11].
Histology shows highly pleomorphic fibroblasts mixed with abnormal histiocytes in a storiform pattern with a background dense inflammation (Fig. 83.5). Phagocytised neutrophils with large nuclei/nucleoli are commonly seen. Necrosis is an uncommon feature, but bizarre giant cells or atypical mitotic figures can be seen on most occasions [30, 34, 40]. The commonest subtype is pleomorphic; less common are giant cell and myxoid types. Immune positivity is seen with α-1-antichymotrypsin, vimentin and Ki-67 [11].
Wide surgical resection is the primary treatment, with consideration given to adjuvant chemoradiotherapy [17, 23]. Whist local recurrence is the norm, regional metastases to lymph nodes are rare. Positive margins predict for treatment failure locally and distant spread, usually to the lungs and liver [23, 33].
11 Liposarcoma
Although liposarcomas are second most common soft tissue tumours, less than 5% occur within the head and neck region. They show a slight male predominance, most commonly presenting between the ages of 30 and 60. Majority arise de novo rather than developing in a lipoma [24]. Patient may demonstrate risk factors such as repeated trauma, irradiation or genetic abnormality (NF-1 gene). The histological behaviour varies from high-grade (pleomorphic, round) to low-grade (myxoid) tumours. The myxoid variant shows lipoblasts arranged within a chicken-wire vascular network in a dense stroma (Fig. 83.6). The pleomorphic type shows significant numbers of highly atypical fat cells along with lipoblasts (Fig. 83.7). The epithelioid variant can be confused with carcinoma [40].
Whilst surgery remains the primary treatment modality, the role of adjuvant radiotherapy should be considered in patients with high-grade lesions and large tumours with positive resection margins. Published literature supports the use of adjuvant radiotherapy in reducing local recurrence from 60 to 40% [19, 20, 24].
12 Rhabdomyosarcoma
These are predominantly childhood tumours, usually affecting those below the age of 12Â years [2, 4, 5]. They show slight male predilection. In contrast to adult sarcomas, up to half of all rhabdomyosarcomas occur in the head and neck sites. The favoured subsites are the orbits, the nasopharynx and the temporal bones [15].
Histologically, at least 70% of the tumours are of embryonal subtype; less commonly, the alveolar subtypes are seen (Fig. 83.8). Immune positivity to desmin, myoglobin and actin is well documented (Fig. 83.9). Cells show finely granular eosinophilic cytoplasm with cross striations with enlarged nucleus. More differentiated tumours may show elongated rhabdomyoblasts and occasional giant cells. Definitive diagnosis is based on myogenesis, multinucleated myoblasts, individual tumour cells with cross striations and dense eosinophilic cytoplasm [41].
Prognostic indicators include the location of the primary, age at presentation and metastatic disease. The survival rates have shown significant improvement: 71% in 2001 vs. 25% in the 1970s [15, 23, 31]. The orbital tumours show the best prognosis with 5-year survival rates exceeding 90% in children [15]. This contrasts with poor survival rates in adults at approximately 30%.
13 Chondrosarcoma
Chondrosarcomas are malignant tumours of the bone or cartilage, and 10% are located in the head and neck [2, 8]. The larynx is the most commonly involved subsite, closely followed by the maxilla and mandible. The peak incidence is 30–50 years. At least 80% arise de novo. Secondary tumours arise in abnormal bone in conditions such as Paget’s disease and fibrous dysplasia [40]. Rarely, extraosseous tumours are seen due to cartilaginous differentiation of primitive cells. Patient’s symptoms depend on location and the extent of local tissue destruction. Despite slow initial progression, multiple metastases can develop rapidly [26]. Radiographic examination may show sunray speculation.
The degree of differentiation can range from well to poorly differentiated tumours. The common subtypes include myxoid and mesenchyme [26]. It is not uncommon for them to show histological similarity to tumours such as chondroblastic osteosarcoma and malignant fibrous histiocytoma. Additionally, low-grade tumours may show benign histology such as chondromatosis or osteochondroma.
Surgery remains the primary treatment modality, possibly driven by the belief that these tumours are radio-resistant. Additionally, irradiating areas such as the skull base can be carried out with conventional external beam photon therapy particularly with new techniques like Intensity modulation radiation therapy (IMRT). The role of proton beam therapy delivering high-energy irradiation has shown local control rates of 85–100% at 5 years [42].
The site of the primary tumour has implications for prognosis; for example, laryngeal primaries do better compared to nasopharyngeal primaries. High-grade and dedifferentiation confers poor prognosis due to early local recurrence and distant metastases. The 5-year overall survival rates are less than 50% vs. 80% or greater for high- and low-grade tumours, respectively.
14 Angiosarcoma
These tumours arise from the endothelial cells lining the vascular or the lymphatic system. They are most common above the age of 62 years and show male predilection with a ratio of 2:1. They can arise in several different sites given the wide distribution of the endothelium. Some lesions are localised and nodular, whilst others are diffused. Regional metastases are less than 20% of patients at presentation. However, distant metastases may be present in up to 45% of patients at presentation, mostly involving the lungs and liver [6,7,8]. The tumours show immune positivity for CD31. Histological examination shows anastomosing and infiltrating channels lined by multilayered endothelial cells with variable atypia (Fig. 83.10). Free-floating endothelial cells of ‘fish in the creek’ pattern with surrounding adnexae and dermal collagen can be a reliable feature [42].
Although surgery is the primary modality of treatment, diffuse lesions can make adequate surgical clearance a difficult task. The reported 5-year survival rates range from 12 to 40%. Predictors of poor survival include location of the primary tumour, size greater than 7 cm at presentation, high-grade and advancing age [1, 20, 23]. Local recurrence is seen in more than 50% of patients with inadequate or positive surgical margins, usually within 2Â years. The role of adjuvant therapies is questionable in achieving adequate loco-regional control and improving survival.
15 Malignant Schwannoma
These are tumours arising in the nerve: peripheral or cranial. They usually affect the neck, followed by sinonasal areas. Involvement of the maxillofacial skeleton is rare. Although there is an association with von Recklinghausen’s disease or neurofibromatosis type 1, sporadic tumours are well recognised [43]. Surgery remains the primary treatment modality. Tracking of the tumour along the nerve sheath limits the resectability, hence the need of adjuvant therapies, be it radiotherapy or chemotherapy.
16 Fibrosarcoma
These tumours often present as an asymptomatic painless mass between 30 and 40Â years of age. History is positive for previous radiation exposure in at least 10% of patients. Histological similarities are seen with malignant fibrous histiocytoma [6, 7, 44]. Surgery remains the mainstay of treatment, with adjuvant radiotherapy aimed at those with inadequate surgical margin and lessons that are high-grade. The reported 5-year survival rates are 80% or greater [22, 23].
18 Synovial Sarcoma
Contrary to the name, synovial sarcomas arise from the pluripotent mesenchymal cells, not the synovial cells. They show a male predilection and a peak incidence between 20 and 40Â years. The common head and neck subsites are the hypopharyngeal and retropharyngeal areas. It is worth noting that up to 50% of patients have pulmonary metastases at presentation [5, 7, 15].
All histological subtypes (monophasic, biphasic, poorly differentiated) are high-risk tumours. Up to 90% of patients have chromosomal translocation (tX: 18) [21]. Prognosis tends to be poor with less than 20% of patients with metastasis at presentation alive at 2Â years. Increasing age, size greater than 5 cm and poor differentiation predict worst prognosis [18, 22].
19 Ewing Sarcoma
These tumours arise in privative neuroectodermal cells and represent 5% of primary tumours. They are second most common malignant tumours of the bone in children. Subtypes include osseous and extraosseous. Metastases at presentation are seen in 20% of patients, mostly involving the lungs [46]. History may be positive of prior childhood malignancies treated with irradiation or chemotherapy. Most patients present with an enlarging mass that may be asymptomatic or painful. Destructive lesions due to osteolysis are evident on radiographs.
20 Conclusion
Sarcomas are aggressive tumours, fortunately rare in the head and neck regions except for rhabdomyosarcoma in children, which has shown good, improved outcomes with current treatment regimens. The primary treatment modality is surgery, often preceded by neoadjuvant chemotherapy and followed by postoperative chemoradiotherapy. Large tumours with a risk of positive surgical margins and histologically high-grade tumours are adverse features. Age is an independent prognostic factor in children and adults with sarcomas arising in Paget’s disease for bone.
Treatment regiments are often institution-dependent and biased. Given the lack of randomised controlled trials and difficulty in interpreting meta-analysis, close cooperation and data sharing between centres can go a long way in improving treatment outcomes for this diverse group of patients.
