Abstract
Soft tissue sarcomas, a rare and extremely low prevalence tumor, has no uniform treatment recommendation because there have been few randomized prospective trials to guide management. Recently, there have been surgical, medical, biologic, and genetic advances toward improved treatment. A multidisciplinary approach at specialized treatment centers should be sought because the skill set necessary to implement these advances can be provided and outcomes improved. Centralized care will be crucial to improving survival and functional outcome because it will allow for patients to be effectively entered into prospective randomized trials and create regional and national tissue banks to generate meaningful data.

Abstract
To identify pertinent indicators for oncologic outcomes in assessing surgery in soft tissue sarcomas, only local recurrences are considered here. Functional outcomes and treatment morbidity, equally important end-points for evaluating surgery quality, are less frequently reported and are not taken into account in this review. Herein, we review recent publications reporting indicators of surgery quality in soft tissue sarcoma treatment. Local recurrence-free interval is the major end-point in evaluating the quality of surgery. Disease-free survival should not be used because the risk factors for metastases are different from those for local recurrence. Five-year local recurrence-free estimations for limb and trunk wall sarcoma should be below 20%, and best approach 10%. The risk of local recurrence depends on tumour biology (i.e. grade) and quality of surgery as defined by the quality of margins. Better than margin width as measured on the tumour specimen, margin quality determined consensually between surgeons and pathologists is the best indicator for local outcome. Quality of margin should be expressed according the UICC residual disease definitions (R0: in sano, R1: microscopic residual disease, R2: macroscopic residual disease). Other important indicators for surgery quality are treatment in specialised centres, a planned, organised surgery, and treatment within a multidisciplinary team. Soft tissue sarcoma should also be treated in specialised centres. Surgery quality depends on obtained margins that are determined best by close collaboration between the surgeon and the pathologist.

Abstract
Soft tissue sarcomas are very rare tumors. Available data are based on only a few prospective randomized trials. Most studies are retrospective, reviewing the results of single institutions. Furthermore, universally accepted treatment protocols for adult patients are lacking. Several prognostic factors have been identified, including grading, tumor size and development of metastatic disease; however, the relevance of other important aspects in the treatment of patients with soft tissue sarcomas remains unknown or subject to controversy. The main issues concern: which surgical margin width is safe from an oncological perspective? Does local recurrence influence survival? Can systemic chemotherapy improve prognosis? Is radiotherapy necessary in every case? Should it be applied pre-, post- or intraoperatively? What is the value of assessing the response after neoadjuvant therapy? These topics are examined in this review.

Abstract
SUMMARY Soft tissue sarcomas are a rare group of mesenchymal tumours that display cardinal signs, which can raise suspicion to their diagnosis. Management in a sarcoma treatment centre by its multidisciplinary team has improved outcome. Good local disease control with limb salvage and adjuvant radiotherapy has considerably reduced the morbidity of previous limb amputation. By the early involvement of a plastic surgeon, tissue reconstruction is optimised and wound complications reduced. This article looks at the contemporary management of soft tissue sarcoma and, in particular, its relevance to the plastic surgeon today.

Abstract
STS are a heterogeneous group of malignant tumors that pose significant management challenges. The cornerstone of therapy for patients who have primary STS remains margin-negative resection. Adjuvant radiotherapy has been shown to reduce the risk of recurrence for extremity and trunk STS, although its role for retroperitoneal STS remains to be defined. Neoadjuvant radiotherapy has some theoretic advantages to postoperative radiation, but its exact role has yet to be determined. Chemotherapy is usually reserved for chemotherapy-sensitive histologic subtypes and for patients who have metastatic STS.

Abstract
We reviewed the medical files of nine patients with localised soft-tissue sarcomas of the extremities treated with surgical resection, free vascularised tissue transfer, and computerised after-loading iridium-192 high dose rate brachytherapy over a period of 8 years. All patients had external beam radiation therapy in fractions with a total dose of 48-52 Gy, followed by surgery at approximately 4-5 weeks post-irradiation. Surgical treatment included wide resection of the primary tumour in six patients, and marginal resection in three patients. Microsurgical reconstruction of the soft-tissue defect used a free vascularised musculocutaneous flap that included the gracilis flap in five patients, the latissimus dorsi flap in four patients, and the radiovolar flap in one patient. Postoperative brachytherapy dose ranged from 12 to 24 Gy. Adjuvant chemotherapy was administered in five patients with large tumours and marginal resection. At a mean follow-up of 36 months, eight patients were still alive with no evidence of local recurrence or distant metastases; all these patients had good cosmetic and functional outcomes. Two patients died with lung metastases; one of these patients had local tumour recurrence. Wound healing problems and seroma formations were observed in two patients. Intramedullary nailing was required in one patient for a pathological fracture. Tumour resection for soft-tissue sarcomas combined with microsurgical reconstruction of the soft-tissue defect, preoperative external beam radiation and high dose rate brachytherapy results in a high degree of local control with acceptable complications.

Abstract
Soft tissue sarcomas comprise a heterogeneous group of malignancies of mesenchymal origin. Although sarcomas can arise virtually anywhere, the most common primary site is the extremity. The development of metastatic disease poses a major clinical problem because it is seldom amenable to a curative treatment. However, with careful and expert multidisciplinary team selection of patients with metastatic sarcoma-balancing probability of benefit with certain toxicity-a combined multimodality approach may provide hope to a select few for prolonged survival and even cure.

Abstract
We have analysed the pattern of symptoms in patients presenting with synovial sarcoma to identify factors which led to long delays in diagnosis. In 35 children, the early symptoms and the results of clinical and radiological investigation were reviewed, along with the presumed diagnoses. The duration of symptoms was separated into patient delay and doctor delay. Only half of the patients had one or more of the four clinical findings suggestive of sarcoma according to the guidance of the National Institute for Clinical Excellence at the onset of symptoms. Of the 33 children for whom data were available, 16 (48.5%) presented with a painless mass and in ten (30.3%) no mass was identified. Seven (21.2%) had an unexplained joint contracture. Many had been extensively investigated unsuccessfully. The mean duration of symptoms was 98 weeks (2 to 364), the mean patient delay was 43 weeks (0 to 156) and the mean doctor delay was 50 weeks (0 to 362). The mean number of doctors seen before referral was three (1 to 6) and for 15 patients the diagnosis was obtained after unplanned excision. Tumours around the knee and elbow were associated with a longer duration of symptoms and longer doctor delay compared with those at other sites. Delays did not improve significantly over the period of our study of 21 years, and we were unable to show that delay in diagnosis led to a worse prognosis. Our findings highlight the variety of symptoms associated with synovial sarcoma and encourage greater awareness of this tumour as a potential diagnosis in childhood.

Abstract
INTRODUCTION Malignant tumors of the musculoskeletal system are rare, and their symptoms are non-specific. The diagnosis of primary malignant tumors of bone or soft tissue by tissue biopsy is necessary before multimodal treatment with chemo- and/or radiotherapy and resection can be provided. These biopsies are straightforward surgical procedures; they must, however, be performed according to the guidelines if high rates of error and complications are to be avoided. METHODS Selective literature review. RESULTS Biopsies are either incisional or excisional. There are guidelines for the performance of both kinds. The biopsy channel is inevitably contaminated with tumor cells and thus must be completely removed together with the tumor. Excisional biopsies are indicated only for the histopathological diagnosis of small (< 5 cm), epifascial soft-tissue tumors and small, slowly growing bony tumors that are considered most likely to be benign. If in doubt, an incision biopsy should be performed. DISCUSSION The complication rate of tumor biopsies is known to be higher when they are performed in an institution without extensive experience in the treatment of sarcoma. Thus, patients with musculoskeletal tumors that are suspected of being malignant should be referred to a suitable tumor center for biopsy.

Abstract
PURPOSE To analyse the management and clinical outcome of patients treated for retroperitonal soft tissue sarcoma and to identify prognosis factors. PATIENTS AND METHODS This is a retrospective study of 20 adults ; 11 women and nine men treated between 1980 and 2000 in our institution. RESULTS There were seven liposarcomas and 13 leiomyosarcomas. The mean tumor size was 26 cm. Three patients underwent a complete resection (R0), 14 patients an incomplete resection (R1/R2) with microscopic or macroscopic tumour remained after surgery. Only three patients had a surgical biopsy. Median follow-up was 18 months. Overall survival rates was 45%, 10% at two and five years, respectively. Among the following factors, sex, age, symptom duration, tumor size, histologic type, histologic grade, resection type, mitotic index, necrosis extension, histologic differentiation, and AJCC stage, only mitotic index factor (scale 1,2 versus scale 3) significantly influenced patient survival (p = 0.02). CONCLUSIONS This study re-emphasizes the poor outcome of patients with retroperitoneal sarcoma. Survival rates appeared low when compared with other studies. These results incite for a more aggressive approach.

Abstract
BACKGROUND The aim was to review a single-institution experience of a prospective treatment protocol for soft tissue sarcoma of the extremity and trunk wall, with particular focus on the smallest surgical margin leading to local control. METHODS The study included 270 patients who had surgery for soft tissue sarcoma at Helsinki University Central Hospital between 1987 and 1997. Resection margins were measured prospectively from tumour specimens. Radiotherapy was administered if the smallest margin measured less than 2.5 cm, irrespective of tumour grade. RESULTS With a median follow-up of 6.6 years, the 5-year local control rate was 76.4 per cent. On multivariable analysis, the smallest surgical margin around the sarcoma (after radiotherapy) was prognostic for local control. A margin of at least 2.5 cm was associated with a local recurrence-free rate of 89.2 per cent at 5 years. Tumour size, depth or grade and patient's age had no independent prognostic effect on local control. CONCLUSION Surgical margin had independent prognostic value for local control. A surgical margin of 2-3 cm provided reasonable local control of soft tissue sarcoma, even without radiotherapy. Radiotherapy is recommended for smaller margins, irrespective of tumour grade.

Abstract
PURPOSE To evaluate whether adjuvant radiotherapy (RT) in extremity and truncal soft-tissue sarcoma (STS) patients with microscopically positive or close margins after excision can achieve comparable local control to that of excision with negative margin plus RT. METHODS AND MATERIALS A total of 150 patients (111 extremity and 39 trunk cases) treated with conserving surgery and adjuvant RT was analyzed. All surgical margins were classified as being a negative margin or a positive or close margin based on pathologic margin width. RT was delivered with a shrinking-field technique in 150 patients (median, 63 Gy). RESULTS All patients were divided into two groups: (A) excision with negative margins plus RT (n = 56) and (B) excision with positive or close margins plus RT (n = 94). Overall, the 5-year local failure-free survival in all patients was 72.9%, and no significant differences were found between the two groups (Group A, 74.7%; Group B, 71.6%). High tumor grade was found to be a significant predictor of local failure. However, Group A was superior to Group B in distant metastasis-free survival (p = 0.02). No significant differences were shown in overall survival between the two groups. CONCLUSIONS In our series, margin status did not predict for LF when adjuvant RT was used. We believe that when adjuvant RT is used, re-resection may not be necessary for selected patients with positive or close pathologic margins in the management of extremity and truncal STS patients.

Abstract
Neoadjuvant chemotherapy for treatment of soft tissue sarcomas is controversial, and the correlation between local recurrence and survival is unclear. Histologic necrosis is a well-documented predictor of survival in patients with malignant bone tumors; however, the association is unknown in patients with soft tissue sarcomas. We assessed the prognostic significance of tumor necrosis for treatment of soft tissue sarcomas. We retrospectively collected data from 82 patients who received neoadjuvant chemotherapy for treatment of soft tissue sarcomas of the extremities. Patients had wide resections if tumors were high-grade, deep to the investing fascia, and had clear margins. We quantified the amount of necrosis and analyzed the relationship with local recurrence and overall survival. At an average followup of 65 months (range, 24-154 months), the 5-year local recurrence rates for patients with less than 95% and 95% or greater necrosis were 20% and 33%, respectively. The overall 5-year survivorship rates for patients with less than 95% necrosis and 95% or greater necrosis were 82% and 78%, respectively. There was no difference in recurrence-free survival or overall patient survival based on the amount of histologic necrosis. Tissue necrosis from neoadjuvant chemotherapy does not seem to predict outcome in soft tissue sarcomas.

Abstract
Soft tissue sarcomas of the popliteal fossa are rare diseases. Resection is challenging because of their extracompartmental location and proximity to neurovascular structures. Their prognosis is inferior to intracompartmental extremity soft tissue sarcomas. We ascertained the mode of initial presentation, the rates of local recurrence and distant metastasis, and the morbidity and complications of limb salvage procedures. We retrospectively analyzed the data of 29 consecutive patients operated on between 1989 and 2003. The median followup was 79 months. Sixteen, five, and eight patients were diagnosed with high-, intermediate-, and low-grade tumors, respectively. High-grade tumors were smaller than low- and intermediate-grade tumors. Thirty-one percent of patients presented with localized pain. Of the 26 patients who had primary limb salvage resections, 14 had negative surgical margins, six had close margins, and six had positive margins. Seventeen patients were treated with radiotherapy and 10 patients received chemotherapy. The local recurrence rate was 10.3%, four patients with high-grade tumors had distant metastasis, and the limb-salvage rate was 86.2%. Postoperatively, six patients experienced wound dehiscence and four had mild flexion contractures. Soft tissue sarcomas of the popliteal fossa have an atypical presentation. Limb salvage can be accomplished in most patients with low morbidity and good systemic and local control.

Abstract
BACKGROUND Prospective application of the French Sarcoma Group (FSG) method of surgery reporting in soft tissue sarcoma (STS) in a single centre. METHODS Patients with primary STS of the extremities or trunk wall consecutively operated at the same institution from January 1996 to December 2002 were evaluated for local recurrence (LR). There were 205 patients, with AJCC/UICC stages III and IV in 51% of cases. Resection types according to FSG were R0 in 147, R1 in 53 and R2 in five cases. Radiotherapy was delivered in 163 patients and chemotherapy in 103. Multivariate analysis was performed. Overall five-year survival was 75%. Median follow-up for surviving patients was 53 months. RESULTS Actuarial five-year LR incidence was 13% in 200 patients with gross resection (R0+R1), it was 7% in R0 and 30% in R1 patients (p<0.0001). At univariate analysis, significant prognosticators for LR were age, histotype, tumour invasion, grade and resection type R. At multivariate analysis, resection R1 (relative risk (RR) 4.3, p=0.001) and grade 3 (RR 3.9, p=0.013) independently predicted LR. Combining these two variables produced three prognostic groups for LR: group 0 (no factor, n=70), group 1 (one factor, n=94) and group 2 (two factors, n=36) with five-year LR of 4%, 12% and 39%, respectively (p=6.4x10(-7)). CONCLUSION This first prospective evaluation of surgery reporting in STS evidences a fourfold, highly discriminating difference in LR between resections R0 and R1.

Abstract
Between 1990 and 2002, 76 patients underwent 102 muscle flap reconstructions for extremity sarcomas. The patients had radical resection with immediate reconstruction. Reconstructions were performed by the Musculoskeletal Oncology and Plastic Surgery services. The mean age of our patients was 39.1 years. Patients were studied for a mean of 25.4 months. There were 79 pedicle flaps and 23 free flaps. Complications occurred in 23.7% of patients, including wound necroses, seromas, postoperative bleeding, postoperative infections, and flap loss. Five patients required a secondary flap procedure. The overall flap survival rate was 98%. Three patients had local recurrences. Sixteen patients (21.1%) have died of their disease. Five patients are alive with metastases. In 54 patients, Musculoskeletal Tumor Society (MSTS) functional evaluation scores averaged 27.1 (range, 12-30). In this large series of patients, we have demonstrated that, although minor complications are common, functional limbs can be salvaged following oncologic resection from the extremities.

Soft tissue sarcomas represent a heterogeneous group of malignant tumors that arise from mesenchymal tissues. The majority of these tumors arise on the extremity or trunk. Despite their rarity, soft tissue sarcomas continue to generate vigorous academic interest, and as a result, the ever-expanding medical literature dealing with sarcomas continues to grow. Many general surgeons will see few of these tumors during their careers, and a review of the current literature and how it applies to patients afflicted with soft tissue sarcoma of the extremity or trunk is warranted.

Abstract
BACKGROUND A consecutive series of 47 patients with retroperitoneal sarcoma (RPS) were resected and prospectively followed. METHOD Between July 1994 and March 2005, 47 patients (24 men, 23 women; mean age, 56 years; range, 17-82 years) were evaluated. RESULTS A total of 23 patients had primary RPS and 24 patients had recurrent RPS. A total of 30 out of 47 patients (64%) underwent removal of contiguous intra-abdominal organs. The peroperative mortality was nil and significant preoperative complications occurred in eight cases only (17%). High tumour grade and incomplete resection were significant variables for a worse survival in all 47 patients, both in the univariate and multivariate analyses (P = 0.008 and P = 0.016, respectively). Among 28 radically resected patients, only histological grade affected overall survival (90% 5-year survival for low-grade tumour vs 26% 5-year survival for high-grade tumour; P = 0.006) with a similar effect noted for disease-free survival. CONCLUSIONS Histological grade was the only factor that affected overall and disease-free survival for RPS tumours. An aggressive surgical approach in both primary and recurrent RPS is associated with long-term survival.

Abstract
BACKGROUND The goal of surgeons treating soft tissue sarcoma is to gain local control, to avoid risk of local recurrence and to avoid compromise of the patient's potential survival. The aim of the investigation was to assess the significance of the extent of surgical margin on the chance of death, metastasis and local recurrence. METHODS Two hundred and seventy-nine patients who presented with soft tissue sarcoma without metastatic disease were analysed. RESULTS The extent of the surgical margin was not clinically or statistically significant in the development of metastatic disease. The presence of a contaminated surgical margin led to a significantly higher rate of local recurrence (as did a narrow surgical margin less than 1 mm). A margin greater than 1 mm allowed a satisfactory outcome in terms of low local recurrence rates. In terms of overall survival, the failure to achieve a wide surgical margin (wide contaminated margin) led to an increased relative death rate. However, when the margin was not contaminated (even if the margin was very close, less than 1 mm), the overall survival rate was similar across all groups. Patients who had radical resections did poorly; they generally belonged to a group in which palliative surgery was carried out, and they showed very high relative metastasis and death rates. CONCLUSION The present study provides statistically significant evidence that increasing the width of resection improves local control and overall survival.

Abstract
The therapeutic approach to soft tissue sarcomas (STS) has evolved over the past two decades based on the results from randomized controlled trials, which are guiding physicians in the treatment decision-making process. Despite significant improvements in the control of local disease, a significant number of patients ultimately die of recurrent/metastatic disease following radical surgery due to a lack of effective adjuvant treatments. In addition, the characteristic chemoresistance of STS has compromised the therapeutic value of conventional antineoplastic agents in cases of unresectable advanced/metastatic disease. Therefore, novel therapeutic strategies are urgently needed to improve the prognosis of patients with STS. Recent advances in STS biology are paving the way to the development of molecularly targeted therapeutic strategies, the efficacy of which relies not only on the knowledge of the molecular mechanisms underlying cancer development/progression but also on the personalization of the therapeutic regimen according to the molecular features of individual tumours. In this work, we review the state-of-the-art of conventional treatments for STS and summarize the most promising findings in the development of molecularly targeted therapeutic approaches.

Abstract
UNLABELLED For this review of surgery in soft tissue sarcoma, we reviewed literature and added our personal experience. In front of a soft tissue tumour, the major objective is to think it could be a sarcoma. Diagnosis actually is made by core needle biopsies, but sometimes a surgical biopsy is needed. Surgical resection is better defined since ten years and distinguishes resection R0 (in sano), R1 (microscopic residual disease) and R2 (macroscopic residual disease). Quality of resection is determined collegially by confrontation of surgical and pathological reports according recommendations of the French Sarcoma Group (FSG). The risk of local recurrence depends on resection-type and tumour grade. With the help of the surgical classification from FSG, local prognosis is better understood and treatment can be adapted to individual tumours. In experienced hands, local recurrence can be pushed down to near 10 against 20% formerly. Severe complications after sarcoma surgery occur in 14% of cases. Functional outcome studies have benefited from new scoring systems, which complete each other. Isolated limb perfusion is a method that could save limbs in some desperate situations. CONCLUSION Due to rarity and treatment specifications, soft tissue sarcoma should be treated in specialised centres.

Abstract
Retroperitoneal sarcomas comprise approximately 15% of all soft tissue sarcomas and 50% of all retroperitoneal tumours. Helical CT of the abdomen and pelvis, with selective use of MRI will establish the extent of the tumour, its retroperitoneal location, the degree of necrosis, and the evidence of metastasis. A CT guided core needle biopsy is the optimal pre operative tissue sampling. A complete surgical resection is the mainstay of the treatment with a rim of normal tissue that often requires removal of adjacent organs. The 5-year probability of local control is approximately 50%. The role of adjuvant therapy is evolving and at present should not be used outside the investigational setting.

Abstract
Nearly all bone and soft tissue sarcomas will require surgical management. Early consultation with a surgeon who is experienced in sarcomas, before a biopsy is performed, will avoid potential errors that may complicate subsequent surgery. Advances in imaging, neoadjuvant therapies, and reconstructive techniques have improved the ability to resect adequately most bone and soft tissue sarcomas. The use of oncologic and functional outcomes assessment tools facilitates the development of improved treatments for sarcoma patients. Results from major centers reveal that most patients who have a nonmetastatic bone or soft tissue sarcoma will survive 5 years after surgery when combined with either chemotherapy or radiation.

Abstract
Despite the overall good prognosis in patients who have localized soft tissue sarcoma (STS) of the extremities, approximately half of those who have high-risk features ultimately will die from metastatic disease that was present as microscopic foci at the time of diagnosis. The principal role of adjuvant and neoadjuvant chemotherapy is to improve the "cure" rate through eradication of these microscopic foci. Over the last 30 years there have been numerous studies attempting to determine whether adjuvant or neoadjuvant systemic chemotherapy does lead to an improvement in disease-specific survival in patients who have localized STS. It is still unclear whether there may be a role for systemic chemotherapy in patients who have high-risk localized STS of the extremities. This article discusses some of the issues surrounding this most controversial area in the management of STS.

Abstract
BACKGROUND: Subcutaneous leiomyosarcoma is a rare condition that accounts for 1% to 2% of all superficial soft tissue malignancies. Approximately 10% of cases arise in the trunk, although the extremities are the most commonly affected. CASE PRESENTATION: We report herein the case of a 31-year-old man with a subcutaneous leiomyosarcoma, measuring 124 x 105 mm, arising in the left inguinal region. A wide local excision (with a resection margin >/= 20 mm) was performed. Histological examination of the resected specimen revealed a leiomyosarcoma with high cellularity and two mitoses per 10 high-power fields. The patient remains well with no evidence of disease 5 years and 8 months after the operation. CONCLUSION: This is the first reported case of subcutaneous leiomyosarcoma arising in the inguinal region and also one of the largest tumors reported. The experience of this case and a review of the English-language literature (PubMed, National Library of Medicine, Bethesda, MD, USA) suggest that a resection margin of >/= 10 mm is recommended when excising this rare tumor.

Abstract
Soft tissue sarcomas are a heterogeneous group of malignancies arising from mesenchymal tissues. Patients can present with a localised tumour (primary or local recurrence) at different sites (e.g., extremity, abdomen) or metastatic disease, which may require different treatment strategies. Is the surgical resection of a localised sarcoma enough or is it better to give an additional treatment like adjuvant and/or preoperative radiotherapy and/or chemotherapy? Which chemotherapy should be selected in the first or second line situation? Do new treatment options exist, such as targeted therapies? This review provides answers to some of these questions. To decide on consecutive treatment steps, it is important to know as many relevant factors as possible at first presentation. Therefore, the first part of this review discusses the specific characteristics and prognostic factors of importance for treatment planning. A short summary of current therapy strategies and existing standards is then given. The main body of the review summarises information on new and emerging clinical compounds for patients with soft tissue sarcoma of adults, including recent developments of targeted therapy.

Abstract
Soft tissue sarcomas (STS) represent a rare entity of all malignant tumors (1%). Thus, an in-depth understanding of multidisciplinary treatment strategies may not be sufficiently present at all operative units. Consecutively, optimal diagnostic and therapeutical pathways may not be applied. Magnetic resonance imaging (MRI) is the procedure of choice in diagnosing STS. Biopsies should be performed in specialized centers. Identification of cytogenetic factors has become more important for the typing and prognosis of STS. Management of STS should employ multimodal treatment concepts (Oncology, Radiotherapy, Surgical Oncology). The decision on whether radiotherapy, chemotherapy or another option is indicated should be taken by an interdisciplinary tumor board, which also determines the sequence of treatment in relation to resection. To obtain sufficient information from histopathologic examination of the resected tumor, a clear and distinct definition of critical margins and topography by the surgeon is essential. Following these concepts, optimal local tumor control associated with resections preserving function and limbs is achieved without impairment of overall prognosis. Tumor resection alone, without previous evaluation and where appropriate adopting multimodal treatment strategies, no longer meets modern standards. After primary treatment is complete, patients have to be enrolled in a standardized follow-up program.
