ABSTRACT
BACKGROUND: With recent conservative strategies, prognosis of patients with desmoid-type fibromatosis (DTF) is about function preservation. We analyzed the long-term quality of life (QoL) of pediatric patients with DTF. METHODS: All French young patients (<21years) treated between 2005 and 2016 for a DTF in the EpSSG NRSTS-05 study were analyzed. A first wait-and-see strategy was recommended. Patients' QoL was analyzed with the internationally validated Child Health Questionnaire (CHQ). We focused on the relevant subscales scores: physical functioning (PF), role social limitations physical (RP), bodily pain (BP), general health perception (GH) and physical (PhS) and psychosocial (PsS) summary measures. RESULTS: Among the 81 patients, 52 families answered the CHQ (median delay since diagnosis = 6.2years; min2.2-max13.3 years). Median age at diagnosis was 11.5 years. Primary site: limbs (52%), head/neck (27%), or trunk (21%). Five year-Progression Free Survival was 39.1% (95%CI: 27.7-50.5%). As initial management for these 52 patients, 30 patients were first observed (57%), 13 had surgery (25%) and 9 received chemotherapy (18%). Total burden of therapy was exclusive surgery (9pts/18%), exclusive chemotherapy (18pts/35%), surgery + chemotherapy (13pts/25%), chemotherapy + radiotherapy (1 pt), surgery + chemotherapy + radiotherapy (1 pt), wait and see (10 pt). Regarding the parent forms, patients have significant lower PF (86.0vs.96.1; p = 0.03), RP (82.0vs.93.6; p = 0.04), GH (60vs.73; p < 0.005) and PhS (46.2 vs.53; p = 0.02) scores compared to healthy population. Comparison of QoL subscales scores according to initial strategy (wait-and-see vs.surgery/chemotherapy) did not reveal any difference (PF = 87.3vs.84.9; p = 0.80/RP = 83.4vs.78.7; p = 0.72/BP = 78.9vs.78.2; p = 0.95/GH = 59.7vs60; p = 0.97). Similar results were found using the children or adult forms. CONCLUSIONS: Initial wait-and-see strategy does not affect long term functional impairment.

PURPOSE: In adults' non-seminomatous germ cell tumours (NS-GCT), alpha-fetoprotein (AFP) decline was identified as an important prognostic factor. We investigated its prognostic value in the French TGM95 study for childhood NS-GCT. PATIENTS AND METHODS: Three risk groups were defined: low risk (LR: localised and completely resected pS1, AFP<15000 ng/ml), with a 'wait-and-see' strategy; intermediate-risk (IR: localised incompletely resected, AFP<15000 ng/ml) with 3-5 vinblastine-bleomycine-cisplatin courses; high risk (HiR: AFP≥15000 ng/ml and/or metastatic) with 4-6 etoposide-ifosfamide-cisplatin courses. The multivariable prognostic analysis for progression-free survival (PFS) included age (±10 years), primary tumour site (1-testis, 2-ovary, 3-extragonadal), extent of disease (1-pS1, 2-loco-regional dissemination, 3-metastasis) and AFP (±10,000 ng/ml). AFP decline prognostic value was investigated in IR + HiR groups using predicted time to normalisation (TTN), AFP change, and difference between observed and expected (based on AFP half-life) area under the curve (O-E AUC). RESULTS: From January 1995 to December 2005, 239 patients (median age = 3years, 60 LR, 65 IR, 114 HiR) were included. Main sites were testis (n = 66), ovary (n = 77) and sacrococcygeal (n = 57). Five-year PFS and OS were 85% (95% confidence interval [CI] = 80-89%) and 93% (89-95%), respectively. Age ≥ 10 years (hazard ratio [HR] = 4.6, 95% CI = 2.1-10.1, p = 0.0001) and extragonadal primary (HR = 6.3, 95% CI = 2.0-19.9, p = 0.005) were significant prognostic factors. In AFP decline analysis (n = 151, 17 events), TTN (p = 0.61) and AFP change (p = 0.10) were not prognostic, whereas we showed a significant effect of O-E AUC (HR = 2.1, 95% CI = 1.0-4.2, p = 0.05). CONCLUSION: Age ≥ 10 years and extragonadal tumours remain as poor prognostic factors. Contrary to adults, TTN is not reliable in paediatric NS-GCT. The prognostic value of O-E AUC should be investigated in larger studies.

PURPOSE: We report the results of a French multicenter retrospective study based on a period of more than 30 years and a review of the literature in order to more clearly define the surgical approach and specific pediatric risk factors. METHODS: Clinical data of children comprising all histologic subtypes of thymic epithelial tumors (TET) treated between 1979 and 2009 in French pediatric oncology centers were retrospectively analyzed and discussed in the light of a review of all pediatric cases reported in the literature. RESULTS: Nine cases were identified, corresponding to five females and four males with a median age of 13 years (range: 7.5-17). Histologic subtypes were type AB (n = 1), type B (n = 5) and type C (n = 3). Treatment consisted of tumor resection (4 R0, 4 R1, 1 R2) via right anterior thoracotomy, posterolateral thoracotomy, left thoracoscopy, sternotomy and cervicosternotomy, and/or chemotherapy, mainly cyclophosphamide-doxorubicin-cisplatin (CAP; n = 5), and/or radiotherapy (n = 4). Two patients with TET type C died. All other patients are alive with a median follow-up of 4 years (range: 1.5-20). Review of a total of 93 pediatric cases reported in the literature showed statistically significant associations between less favorable histologic subtypes and male gender (P = 0.012), advanced Masaoka stage (P < 0.001) and quality of resection (P < 0.001) respectively. CONCLUSIONS: A review of the literature and our series identified several risk factors to take into account in the therapeutically decision. Complete resection through a sternotomy is highly recommended.

BACKGROUND: Mandibular osteosarcomas (MOS) mostly affect young adults. Their treatment is extrapolated from that of extragnathic osteosarcomas. MATERIAL AND METHODS: A retrospective multicooperative group study was conducted to determine the impact of chemotherapy, adjuvant radiation therapy and surgery on outcomes and to identify prognostic factors. This ethical committee-approved study included a centralized review of histology slides and operative reports. RESULTS: Of 111 patients, 58.6% were male, median age 35 years (13%, ≤18 years). Histology was osteoblastic, chondroblastic, fibroblastic, conventional not otherwise specified and others in 39.6%, 30.6%, 8.1%, 12.6% and 8.0%, respectively. Pathological World Health Organisation grades were low, intermediate and high grade in 6.4%, 11.8% and 81.8%, respectively. Surgery was carried out for 94.5% of patients. Neoadjuvant chemotherapy (mixed protocols) was carried out in 93.1% of patients. Postoperative chemotherapy and radiotherapy were carried out in 54.7% and 23.8%, respectively. Median follow-up was 59.6 months (range). Five-year local control, metastasis-free, disease-free and overall survival rates were 64.6%, 68.9%, 53.2% and 69.2%, respectively. Survival was significantly associated with age, tumor size and surgery. Wide surgery with clear margins and free flap reconstruction was the strongest prognostic factor. Neoadjuvant chemotherapy improved disease-free and metastatic-free survival and increased clear margins rates from 50% to 68%. Intermediate grades behaved like high grades in terms of metastatic-free and disease-free survival. CONCLUSION: This homogeneous series is the largest to date and emphasizes the major impact of clear margins and multidisciplinary management. Neoadjuvant chemotherapy improves disease-free survival and should be recommended for both high and intermediate grade MOS.
