ECCO Essential Requirements for Quality Cancer Care: Soft Tissue Sarcoma in Adults and Bone Sarcoma. A critical review.

BACKGROUND: ECCO essential requirements for quality cancer care (ERQCC) are checklists and explanations of organisation and actions that are necessary to give high-quality care to patients who have a specific tumour type. They are written by European experts representing all disciplines involved in cancer care. ERQCC papers give oncology teams, patients, policymakers and managers an overview of the elements needed in any healthcare system to provide high quality of care throughout the patient journey. References are made to clinical guidelines and other resources where appropriate, and the focus is on care in Europe. Sarcoma: essential requirements for quality care • Sarcomas - which can be classified into soft tissue and bone sarcomas - are rare, but all rare cancers make up more than 20% of cancers in Europe, and there are substantial inequalities in access to high-quality care. Sarcomas, of which there are many subtypes, comprise a particularly complex and demanding challenge for healthcare systems and providers. This paper presents essential requirements for quality cancer care of soft tissue sarcomas in adults and bone sarcomas. • High-quality care must only be carried out in specialised sarcoma centres (including paediatric cancer centres) which have both a core multidisciplinary team and an extended team of allied professionals, and which are subject to quality and audit procedures. Access to such units is far from universal in all European countries. • It is essential that, to meet European aspirations for high-quality comprehensive cancer control, healthcare organisations implement the requirements in this paper, paying particular attention to multidisciplinarity and patient-centred pathways from diagnosis and follow-up, to treatment, to improve survival and quality of life for patients. CONCLUSION: Taken together, the information presented in this paper provides a comprehensive description of the essential requirements for establishing a high-quality service for soft tissue sarcomas in adults and bone sarcomas. The ECCO expert group is aware that it is not possible to propose a 'one size fits all' system for all countries, but urges that access to multidisciplinary teams is guaranteed to all patients with sarcoma.

Management of desmoid tumours: A nationwide survey of labelled reference centre networks in France.

PURPOSE: The optimal management of rare tumours (i.e. from accurate diagnosis to management in reference centres) is a public health challenge. In 2009, the French National Cancer Institute (INCa) identified and financially supported the two expert networks for pathological and clinical diagnosis and management of soft tissue tumours. METHODS: The activities of both networks were prospectively collected using a nationwide database (rreps.org). Data describing the diagnosis management of 863 successive cases of desmoids tumours (DT) were prospectively collected from 2010 to 2013 and analysed. RESULTS: The number of confirmed DT constantly improved from January 2010 to December 2013 (from 173 to 273 cases per year); the expected incidence ranged from 132 to 330 cases/year. The rate of cases diagnosed with core-needle biopsies and CTNNB1 mutational status analysis increased from 30.6 to 40.7% and from 87.8 to 94.1%, respectively. The mean delay for pathological diagnosis confirmation constantly decreased from 107 to 47 d. Among the 846 adult patients, 414 (48.9%) patients were treated by reference centres. The rate of patients managed by reference centres constantly increased with time from 36.9 to 49.5% since 2010. The median management time of the referral centres constantly decreased from 440 to 67 d. CONCLUSION: The two expert networks worked synergistically and improved diagnosis modalities of rare desmoid tumours at a national level. The impact of management by expert networks on the outcome will be prospectively analysed in the future.

Algorithm for the surgical management of mesenchymal tumors of the perineum in adults.

BACKGROUND: Perineal soft tissue tumors are rare, so that little is known about their management and the outcome of treatment. OBJECTIVE: The aim of this study is to describe the presentation, management, and outcome of the surgical treatment of soft tissue tumors and to provide a final decision algorithm. DESIGN: This is a retrospective study. SETTINGS: The study was conducted in a single tertiary care hospital with a dedicated unit on sarcoma. PATIENTS: Fifty-one consecutive patients from 1998 to 2013 were included. MAIN OUTCOME MEASURES: The primary outcomes measured are patient demographics, treatment decisions, and outcome of surgical treatment. RESULTS: Forty-nine patients presented with a primary soft tissue tumor, and 2 underwent simple excisions for isolated metastases. The median tumor size was 75 mm (50-110). Symptoms were nonspecific, and MRI had insufficient specificity for malignancy so that a preoperative biopsy was systematically performed according to European Society for Medical Oncology and National Comprehensive Cancer Network soft tissue tumor guidelines. Six benign soft tissue tumors (3 lipomas, 3 leiomyomas), 16 intermediate soft tissue tumors (12 aggressive angiomyxoma, 4 desmoid tumors), and 27 sarcomas were identified. Treatments and surgery were tailored from the beginning according to histology. All but 1 benign soft tissue tumor were treated by 'shelling out.' Aggressive angiomyxoma were treated with en bloc resection sparing uninvolved organs. Nonsurgical treatments were our first choice for desmoid tumors. Wide en bloc surgery was planned for all sarcomas (n = 27) after the induction treatment for 16 patients (chemotherapy, n = 12; radiotherapy, n = 4). In the sarcoma group, the 5-year estimated metastasis-free, local recurrence-free, and overall survival rates were 68.1% (95% CI, 50.7-91.5), 84.7% (95% CI, 66.7-100), and 85.7% (95% CI, 71.8-100). In the benign and intermediate tumor groups, there were no deaths, local recurrences, or progression. LIMITATIONS: This study was limited by the small number of patients, given the rarity of this disease in the perineum. CONCLUSION: We provide useful indications for the best strategy necessary to treat these rare tumors located in a complex site.

Hyperthermic pelvic perfusion with tumor necrosis factor-α for locally advanced cancers: encouraging results of a phase II study.

PURPOSE: To assess the efficacy of isolated pelvic perfusion (IPP) with tumor necrosis factor (TNF)-α and melphalan in patients with locally advanced cancers in the pelvic and groin area requiring mutilating surgery. METHODS: A total of 27 patients were enrolled (carcinoma, n = 17; sarcoma/melanoma, n = 4; and endocrine tumor, n = 6). They were candidates for exarticulation (n = 3) or exenteration (n = 11) or were judged unresectable (n = 13). In installing IPP, tourniquets were positioned around both thighs, and an inflated pressure suit was placed at a subthoracic position. Tumor necrosis factor-α (300 µg) was injected in the perfusate, followed 5 minutes later by melphalan at 1.5 mg/kg. After 30 minutes, the remaining drugs were washed out. Leakage was assessed with technetium Tc 99m radiolabeled human serum albumin, and a pharmacokinetic study was performed. Efficacy was based on the complete response rate observed on magnetic resonance imaging. RESULTS: Pelvic/systemic ratios of melphalan/TNF/technetium Tc 99m were 14.2/7/3.6. Responses on magnetic resonance imaging were as follows: 30% complete, 30% partial, 19% no change, and 15% progression. Two patients were not evaluable because they did not receive the treatment. Pre-IPP/post-IPP median percentage of necrosis on magnetic resonance imaging was 10%/70%. Median follow-up was 43 months. Median overall survival was 17 months. Twelve-month survival rate, disease-free survival, and local and metastatic recurrence rates were 67%, 30%, 57%, and 26%, respectively. CONCLUSIONS: Isolated pelvic perfusion with TNF-α compares favorably with historical data, as it was observed in limb perfusion and could provide a chance to translate its successful combination with chemotherapy into treatment of locally advanced pelvic cancers.

Hyperthermic isolated limb perfusion in locally advanced soft tissue sarcoma and progressive desmoid-type fibromatosis with TNF 1 mg and melphalan (T1-M HILP) is safe and efficient.

BACKGROUND: In a prior randomized phase II trial comparing hyperthermic isolated limb perfusion (HILP) with four different doses of tumor necrosis factor alpha (TNF-alpha), no dose effect was detected for response, but systemic toxicity was far lower with low-dose TNF-alpha. The objective of the present study was to confirm these data on a larger sample size of locally advanced or recurrent extremity soft tissue sarcomas with low-dose TNF-alpha. METHODS: We assessed a prospective database comprising 100 HILP (38-40 degrees C) with melphalan (10 mg/L) and TNF-alpha (1 mg). The remnant tumor was resected 2 months later. RESULTS: Among 52 recurrences, 18 were in a previously irradiated field. Stages according to the American Joint Committee on Cancer classification were II (19 patients), III (78 patients), and IV (3 patients). The site/size were: 30 patients/57 mm and 70 patients/86 mm for the upper and lower limbs, respectively. Tumor grades (FNCLCC) were 1 (23 patients), 2 (34 patients), and 3 (43 patients). Fifty-one patients had received systemic chemotherapy before HILP. Responses on magnetic resonance imaging were 30% complete, 49% partial, 9% no change, and 12% progression. No mortality or systemic toxicity occurred. Local toxicity (Wieberdink) attained grade 2 (16 patients), 3 (5 patients), and 4 (1 patient). Limbs were able to be saved in 87% patients. Three-year overall survival and the local recurrence rate were 89% and 18%, respectively. Age, sex, tumor size, recurrence, uni- or multifocality, grade, preoperative chemotherapy, and a previously irradiated field were not predictive of response or local toxicity. CONCLUSIONS: We confirm that 1 mg of TNF-alpha is as effective as the standard dose and results in no systemic toxicity.
