RESUMO
INTRODUCTION: Despite regular recommendations issued by the European Society for Medical Oncology (ESMO), patients faced still too often inadequate care with a direct influence on prognosis. METHODS: A retrospective study was carried out at the Competence center in Lorraine Area. Patients registered in the NetSarc database between 1st, 2010 and September 1st, 2016 were included. Compliance criteria were established using the latest ESMO 2014 referential. Two groups "conforming" and "non conforming" were analyzed. A first analyze about all of the soft tissue lesion and a second only about sarcomas. RESULTS: In total, 445 patients were eligible, 344 cases were treated according to the ESMO guidelines, giving a 77.3% conformity rate (95% CI: 73.4%, 81.2%). Compliance was better for the competence center than district hospitals (P<0.001), with compliance rates of 88.7%, and 51.6%, respectively. Among the 247 sarcomas, we found a R0 resection rate better according to the ESMO guideline, 55% against 18% (P<0.001). R1 rates were 34% vs. 56% and R2 11 vs. 26% disease free survival was not related significantly to the observance of recommendations in the univariate analysis. After adjustment on potential DFS prognostic factors, in the multivariate analysis, the results were similar. CONCLUSION: Compliance with the ESMO guidelines, through appropriate management, improves the quality of surgical excision for sarcomas and avoids non-corresponding surgical gestures.

PURPOSE: To evaluate the impact of hormonal therapy on MRI characteristics of desmoid-type fibromatosis on T1-weighted, T2-weighted fat-saturated and post-contrast sequences. MATERIALS AND METHODS: Nineteen patients with histologically-proven desmoid-type fibromatosis were prospectively followed up on MR imaging. Eight patients underwent hormonal therapy and 11 were only surveyed. Change in tumor size during follow-up was analyzed according to RECIST. Signal intensity on T1-weighted, T2-weighted fat-saturated and T1-weighted fat-saturated post-contrast images was graded from 0 to 5 using adjacent normal muscle as reference. Findings were compared with tumor growth and treatment option. RESULTS: There were seven men and 12 women with a mean age of 42.2±16.4 (SD) years (range: 18 - 64 years) yielding twenty-six follow-up periods: eight of tumor progression and 18 of tumor stability/regression (some tumors exhibited more than one behavior type). Hormonal therapy was associated with tumor stability or regression (P=0.0207). There was a significant reduction in enhancement among treated patients with stable/regressing disease (P=0.049). The mean variation in enhancement grade was -1.3±1.2 in these patients. All successfully treated patients presented a reduction in enhancement. Lesions with marked low enhancement or very low signal on T2-weighted images were rare in progressing lesions (0% and 13%). CONCLUSION: Hormonal therapy has an impact on desmoid-type fibromatosis signal characteristics reducing lesion enhancement.

PURPOSE: GANEA2 study was designed to assess accuracy and safety of sentinel lymph node (SLN) after neo-adjuvant chemotherapy (NAC) in breast cancer patients. METHODS: Early breast cancer patients treated with NAC were included. Before NAC, patients with cytologically proven node involvement were allocated into the pN1 group, other patient were allocated into the cN0 group. After NAC, pN1 group patients underwent SLN and axillary lymph node dissection (ALND); cN0 group patients underwent SLN and ALND only in case of mapping failure or SLN involvement. The main endpoint was SLN false negative rate (FNR). Secondary endpoints were predictive factors for remaining positive ALND and survival of patients treated with SLN alone. RESULTS: From 2010 to 2014, 957 patients were included. Among the 419 patients from the cN0 group treated with SLN alone, one axillary relapse occurred during the follow-up. Among pN1 group patients, with successful mapping, 103 had a negative SLN. The FNR was 11.9% (95% CI 7.3-17.9%). Multivariate analysis showed that residual breast tumor size after NAC ≥ 5 mm and lympho-vascular invasion remained independent predictors for involved ALND. For patients with initially involved node, with negative SLN after NAC, no lympho-vascular invasion and a remaining breast tumor size 5 mm, the risk of a positive ALND is 3.7% regardless the number of SLN removed. CONCLUSION: In patients with no initial node involvement, negative SLN after NAC allows to safely avoid an ALND. Residual breast tumor and lympho-vascular invasion after NAC allow identifying patients with initially involved node with a low risk of ALND involvement.

BACKGROUND: Mastectomy with immediate breast reconstruction (IBR) is a surgical strategy in breast cancer when breast-conserving surgery is not an option. There is a lack of evidence showing an advantage of mastectomy plus IBR over mastectomy alone on health-related quality of life (QoL). METHODS: A large prospective multicentre survey, STIC-RMI (support of innovative and expensive techniques - immediate breast reconstruction), was undertaken to study the changes in QoL in patients treated by mastectomy with or without IBR. Patients were recruited between 2007 and 2009. European Organisation for Research and Treatment of Cancer QLQ-C30 and QLQ-BR23 instruments were used to assess QoL before operation, and at 6 and 12 months after surgery. A propensity score was used to compare QoL between mastectomy alone and mastectomy plus IBR, with limited bias. RESULTS: A total of 595 patients were included from 22 French academic hospitals, of whom 407 (68·4 per cent) underwent IBR. One-year data were available for 71·1 per cent of patients. Factors associated with IBR were age, histological tumour type, palpable nodes and an attempt at breast-conserving surgery. At inclusion, QoL was significantly better in the IBR group (P < 0·001) and there was no significant change in either group during 1 year compared with baseline. Results for the QLQ-BR23 functional dimension varied according to propensity score quartiles; IBR had no influence in the lowest quartile. In the upper quartiles, QoL increased slightly over the year among patients who had IBR, whereas it decreased among those who had mastectomy alone (P = 0·037). Satisfaction with the cosmetic outcome strongly influenced QoL, especially in upper quartiles (P < 0·001). However, an unsatisfactory outcome after IBR was still considered a better condition than simple mastectomy. CONCLUSION: The QoL benefit provided by IBR depends on patients' life status at inclusion; young active women with an in situ tumour are more likely to preserve their QoL after IBR.

Soft tissue sarcomas are rare malignant tumors with a great variety of histological types and different response to multimodality treatment. Pazopanib has been recently introduced for the treatment of non-adipocytic metastatic soft tissue sarcomas which are resistant to conventional chemotherapy. Spontaneous pneumothorax is a rare but well recognized complication of this molecule and its treatment is quite challenging. The case reported herein describes the surgical management of a simultaneous bilateral spontaneous pneumothorax in a patient with pulmonary metastases treated with pazopanib. It underlines the fact that the main objective should be the maintenance of the treatment in patients who benefit from it. Close oncologic and surgical collaboration is crucial in order to deal with adverse effects due to the anti-angiogenic action of pazopanib.

AIM: Sentinel lymph node (SLN) biopsy was recently recommended after prior breast tumour surgery and lymphadenectomy is not the gold standard anymore for nodal staging after a lesion's removal. The purpose of our study was to evaluate the good practices of use of SLN biopsy in this context. PATIENTS AND METHODS: From 2006 to 2012, 138 patients having undergone a surgical biopsy without prior diagnosis of an invasive carcinoma with a definitive histological analysis in favour of this diagnosis were included in a prospective observational multicentric study. Each patient had a nodal staging following SLN biopsy with subsequent systematic lymphadenectomy. RESULTS: The detection rate of SLN was 85.5%. The average number of SLNs found was 1.9. The relative detection failure risk rate was multiplied by 4 in the event of an interval of less than 36 days between the SLN biopsy and the previous breast surgery, and by 9 in the event of using a single-tracer detection method. The false negative rate was 6.25%. The prevalence of metastatic axillary node involvement was 11.6%. In 69% of cases only the SLN was metastatic. The post-operative seroma rate was 19.5%. CONCLUSION: Previous conservative breast tumour surgery does not affect the accuracy of the SLN biopsy. A sufficient interval of greater than 36 days between the two operations could allow to improve the SLN detection rate, although further studies are needed to validate this statement. CLINICAL TRIAL REGISTRATION NUMBER: NCT00293865.

Women who have undergone surgical treatment for breast cancer often benefit from a contralateral reduction mammaplasty (CRM) aimed at symmetrization of the contralateral breast unaffected by the initial cancer. In our 7-year multicentric study (12 centers) of 2718 patients, incidence of CRM cancers (CRMc) was 1.47% (n = 40) [95% CI 1.05%-2.00%]. The CRMc group had significantly more initial mammary cancers of invasive lobular carcinoma (ILC, 22.5% vs 12.0%) and ductal carcinoma in situ (DCIS, 35.0% vs 21.6%) types than the healthy CRM group (p = 0.017). 35.0% (n = 14) of patients had en bloc resection; 25.0% (n = 10) of surgical specimens were correctly oriented. En bloc resection and orientation of surgical specimens enable precise pinpointing of the CRMc. A salvage lumpectomy may be proposed as an option when margins are invaded. The histological distribution of the 40 CRMc (mean size 12.7 mm) was carcinoma in situ (CIS) 70%, ILC 12.5%, invasive ductal carcinoma (IDC) 12.5% and tubular carcinoma (TC) 5.0%.

BACKGROUND: Reconstruction of the mandible with microvascularized fibula transplants is actually a well-established procedure, yet the major component is the limited diameter of the diaphysis that can induce oral rehabilitation's failure, especially in dentate patients. In this paper, we report our surgical procedure allowing preservation of the mandibular height. The primary objective was to assess aesthetic and functional improvements of preservation of an osseous mandibular rim with a fibula free flap reconstruction. PATIENTS AND METHODS: Five patients (all males, mean age of 60 years) were treated with this method. Aetiologies were tumour in 3 cases, and osteoradionecrosis in the two others cases. We described all step of our surgical procedure and the functional, aesthetic and carcinologic results were evaluated. The follow up varies from 6 to 30 months. RESULTS: One patient died at 12 days from unrelated affection. For the other patients, both the aesthetics and functional outcomes were better than in case of mandibular interruption surgery. In fact, the mandibular contour of the mandibule was preserved and the height of mandible was restored. One patient is in progress of dental rehabilitation with osseous implants. Carcinologically, no local recurrence was observed. CONCLUSION: This technique is reliable and enables to optimize oral rehabilitation with endosteal implants. Nevertheless, we consider that the 3D scanner is essential before the intervention to evaluate the osseous reach. Moreover, if necessarily the procedure can be modified intraoperatively.

INTRODUCTION: Breast carcinomas are the most frequent form of cancer in French women. Following a total mastectomy, only an estimated 25% of patients wish to undergo breast reconstruction. After mammary volume reconstitution, the plastic surgeon often attempts to harmonize the two breasts by carrying out contralateral reduction mammaplasty (CRM). In the literature, the incidence of occult contralateral carcinomas incidentally discovered in surgical specimens ranges from 1.12 to 4.5%. The main objective of this study was to evaluate occurrence of carcinoma in the CRM specimens in the framework of a breast reconstruction operation. The secondary objective was to determine the consequences of the incidentally discovered carcinoma in the contralateral breast. MATERIAL AND METHODS: This was a 6-year, bicentric, retrospective study involving women having undergone breast cancer surgery who later underwent contralateral reduction mammaplasty (CRM), that is to say reconstruction aimed at harmonization of the two breasts. RESULTS: Three hundred and nineteen patients were included in the study. Mean age during the CRM was 55years (29-79). Mean weight of the surgical specimens was 323grams (12-2500). Incidence of occult carcinomas found in the specimens was 0.94% (3 patients). The mean age for these 3 cases was 58years (47-64). All 3 patients had superior pedicle mammaplasty. One of the patients benefited from monobloc resection with orientation of the surgical specimen. In the other 2 cases, there existed 3 surgical resection specimens; in one case, they were oriented; in the other, they were not. In all 3 cases, the histological findings were unifocal ductal carcinomas in situ (DCIS). Mean tumor size was 5.7mm (3-9). Only the patient having had monobloc resection with orientation of the specimen underwent salvage surgery, which consisted in partial mastectomy, otherwise known as secondary lumpectomy. Adjuvant radiotherapy was administered to all of the patients. After 17months of mean follow-up (12-22), no recurrence was found in any of the three cases. CONCLUSION: Incidence of occult contralateral breast carcinomas after symmetrization CRM approximates 1%. Our observations are in agreement with the data in the literature. Incidence is greater than in mammaplasty carried out for esthetic or functional reasons; this is probably due to the higher age and the previous breast cancer history of the breast reconstruction population. Monobloc resection and orientation of the surgical specimens with surgeon's knots facilitate precise pinpointing of the occult carcinoma. A secondary lumpectomy may take place when margins of excision are invaded or inadequate.

Granulosa cell tumors of the ovary are rare tumor of ovary, included in the sex cord-stromal tumor category, hormone secreting. Seventeen patients with adult-type granulosa cell tumor were identified between 1995 and 2012. All have received surgical treatment first at stage I. Thirty-three percent of the patients relapsed with peritoneal nodules in 68% of the cases, treated surgically and sometimes with complementary therapies, such as chemotherapy, radiotherapy, hormonal treatment. Overall survival and recurrence-free survival were 100% and 58.3%, respectively at 10 years with median time to recurrence of 6 years (4-27). These tumors have therefore a good prognosis and require long-time follow-up. Finally, the prognostic factors of recurrence identified in the literature are FIGO stage, the presence of residual tumor and tumor size.

PURPOSE: Surgical resection remains the standard treatment for patients with resectable retroperitoneal sarcomas. The aim of this study was to retrospectively analyse the outcomes of patients with primary retroperitoneal sarcoma. PATIENTS AND METHODS: We analysed data of 50 patients with primary retroperitoneal sarcoma who underwent curative-intent resection from 1975 to 2008. External beam radiotherapy and chemotherapy were delivered postoperatively. Demographics, surgical, pathological variables and chemo/radiation therapy were analysed as prognosis factors. RESULTS: There were 22 males and 28 females (mean age 54 ± 13 years). Surgery required visceral resections in 30 patients. There were 16 leiomyosarcomas, 25 liposarcomas and eight other sub-types. Twenty-one patients had clear surgical margins. Twenty-eight patients received postoperative external beam radiotherapy (median 45 Gy) and 15 received chemotherapy. At the end of the follow-up (median 55 months), local recurrence occurred in 39% (n=14) among R0/R1 resection group (n=36). Postoperative external beam radiotherapy tends to increase the time of local recurrence from surgery (27 vs. 13 months, P=0.05). The overall survival rates were 81%, 55% and 46% at 1, 3 and 5 years, respectively. Although R0 resection (P=0.01), well tumour differentiation (P=0.004) and postoperative external beam radiotherapy (P=0.02) significantly influenced overall survival in univariate analysis, only R0 resection was an independent prognostic factor in a multivariate analysis. CONCLUSION: We confirm the pre-eminence of radical surgery with negative margins as major prognostic factor and the benefit of postoperative radiotherapy.

PURPOSE: We have studied the post-treatment follow-up of patients with history of limb soft tissue sarcoma including MR imaging to determine its added value compared to simple clinical follow-up and the impact of MR imaging findings on patient management. We have also studied the value of chest CT to detect metastases. PATIENTS AND METHODS: Retrospective study of 85 patients treated for limb soft tissue sarcoma with post-treatment MR imaging of the affected region. We have studied the percentage of local recurrences and the modality of detection of these recurrences. We have evaluated the impact on management of patients with abnormalities detected on MRI. For distant metastases, we have recorded their percentage and date of occurrence. RESULTS: There were five cases of local recurrence, for a percentage of 6%, with 50% detected clinically. The percentage of metastases was 26%. Six biopsies were performed and complementary examinations were performed in 18 cases based on abnormalities detected on MR. CONCLUSION: These results are in keeping with recommendations from the Fédération nationale des centres de lutte contre le cancer. Imaging is necessary to detect lung metastases.

AIMS: To review a series of 23 consecutive patients with squamous cell carcinomas arising from oropharynx who underwent infra hyoid musculo-cutaneous flap reconstruction including soft palate in alternative to free radial forearm flap or maxillofacial prosthesis. Post operative radiotherapy was performed for all patients. RESULTS: Every reconstruction healed quickly without major wound complications. The functional results evaluated by speech and swallowing capacities, were good for 17 patients, fair for 4 patients and bad for 2. CONCLUSIONS: The infra hyoid musculo-cutaneous flap is a versatile, reliable and convenient flap suitable for repairing small and medium sized defects; it can be used in combination with other flaps, and in selected cases obviates the need for a microvascular free radial forearm flap or maxillofacial prosthesis.

OBJECTIVE: To make a development on the recent data of the literature concerning the functional anatomy of the lymphatic drainage of the breast, observed during interventions of sentinel lymph node biopsy; to compare the descriptive anatomy taking into consideration these new results. METHODS: The population of our descriptive anatomical study is made-up of five patients. All the patients underwent a radical mastectomy during which, an injection of 2 ml of patented blue, realized at the periareolar area allowed to observe the glandular lymphatic vessels. Bibliographic researches were undertaken on Internet site of the National Library of Medicine and on Internet site of the library of anatomy (Faculté de médecine des Saints-Pères Paris). RESULTS: Lymphatic anatomy of the breast was described since more than one century starting from works undertaken on anatomical subjects. Recent works, completed during sentinel lymph node biopsy, enriched these descriptive data of new functional anatomical data on the lymphatic drainage of the breast. Thus, the superficial ways of lymphatic drainage already described by Sappey, drain the surface glandular parenchyma until in the axillary lymph node. A deep plexux described more recently by Hidden drain the deep glandular parenchyma until in the internal mammary lymph nodes and the axillary lymph nodes. The results of our in vivo study corroborated the descriptive and functional data ever known. CONCLUSION: Thanks to the sentinel lymph node biopsy technique, the descriptive anatomy described since 1885, grows rich by new functional data which make it possible on the one hand, to understand at best the descriptive anatomy, and on the other hand, to apprehend the lymphonodal metastatic risk in breast cancer. These recent data are of an interest real, as well anatomical as therapeutic, and constitute a interesting research orientation.

BACKGROUND: Telerobotic-assisted laparoscopic attempts to provide technological solutions to the inherent limitations of traditional laparoscopic surgery. The aim of this study is to report the first experience of two teams concerning telerobotic-assisted laparoscopic hysterectomy for benign and malignant pathologies. METHODS: This study included 14 patients at the University Hospital Saint Pierre of Brussels (Belgium) and 16 patients at the Cancer Center of Nancy (France) from September 1999 to July 2003. RESULTS: The indications for surgery were uterine malignant diseases in 12 cases (stade I) (41%), and benign pathologies of the uterus in 18 cases (59%). Five postoperative complications (17%) occurred, none related to the robotic system. CONCLUSION: Robotic surgery can be safely performed in gynecologic and gynecologic-oncologic surgery with no increase in complication rates. A significant advance is represented by the surgeon's ergonomic improvement.

BACKGROUND: Radiofrequency (RF) is a method of in situ destruction of liver tumor. Biliary complications are bile ducts stenosis or biliary abcess. The aim of this work was to study consequences of liver RF on bile ducts. METHODS: A porcine model of biliary lesions was created using radiofrequency ablation liver. Twenty-two pigs were used for the study. The RF RITA 1500 generator (RITA Medical Systems, Mountain View, Calif., USA) was used for all experiments. The needle was positioned under sonographic control in liver parenchyma beside bile ducts. Two lesions were performed in left liver. Four groups of 5 pigs were treated. The pigs were sacrificed 1 or 3 weeks after the procedure. Pringle maneuver was utilized in half of the RF procedures. An ex vivo cholangiogram was obtained by direct injection into the main bile duct. Samples of RF lesions of liver parenchyma near and at a distance from the RF lesions were taken for pathological studies. RESULTS: Radiological lesions were biliary stenosis, with or without upstream bile duct dilatation, or complete interruption of the bile duct, or extravasation of the radiological contrast agent. Histological lesions of bile ducts were observed near RF lesions and at distance of the RF lesions when a Pringle maneuver was used or when the liver was removed after 3 weeks. CONCLUSIONS: RF ablation in contact of the intrahepatic bile duct induced biliary lesions. Therefore, it is required to stay away from the bile duct or to protect it when performing RF ablation.

PURPOSE: Breast cancer rarely occurs in very young women, its diagnosis and management could sometimes be difficult. Our aim is to analyse the epidemiological and clinicopathological features of a group of very young women and especially to evaluate the results of therapeutic strategy. METHODS: We report a retrospective study conducted at the department of radiotherapy in Alexis-Vautrin Centre, concerning 30 patients aged < or = 30 years in whom a diagnosis of invasive breast carcinoma was made between 1986 and 2001. RESULTS: Six patients had familial history of breast cancer. Palpable tumor was found in 90% of cases, the average size was 3.5 cm. Eleven patients presented with stage I, 11 presented with stage II, 6 presented with stage III and 2 presented with stage IV. Five cancers were diagnosed after pregnancy (average tumor size = 5.8 cm). Eleven patients received neoadjuvant chemotherapy and 23 (82%) of 28 operable cases of invasive malignancy underwent breast conservative surgery (BCS). We found an invasive ductal carcinoma with grade III in 13/27 cases and a nodal involvement in a half of cases, 11 patients of 26 had no expression of oestrogen receptor. The average follow-up was 5 years: six patients (20%) recurred locally (all of them were initially treated by BCS), four patients developed a contralateral breast cancer and three developed a second malignancy. Ten patients died of their metastatic disease. The 5-year overall survival rate was 78%. CONCLUSION: Our results are consistent with those of the published reports and suggest that very young women with breast cancer have a poorer prognosis compared with the older ones. They should receive, according to their prognostic factors, an appropriate regional, systemic and hormonal therapy.

PURPOSE: To retrospectively assess the efficacy of post-mastectomy re-irradiation for local relapse of breast cancer. PATIENTS AND METHODS: Twenty patients, initially treated by conservative surgery and radiotherapy (50 Gy in 25 fractions over 5 weeks) were treated from 1998 to 2001 for a local relapse by salvage mastectomy and re-irradiation (either electron or photon beams). Mean age was 53 years (31-71). Reasons for re-irradiation were that the local relapses were inflammatory (4 pts), multifocal (5 pts), cutaneous (5 pts), involved the nipple (3 pts) or because the surgical margins (either muscle or skin) were involved (3 pts). The median dose of re-irradiation was 45 Gy (33-65) in 15 fractions over 33 days. Mean follow-up was 48 months (5-97). RESULTS: Fifteen patients remained free of a second local recurrence and 10 were still alive, without metastasis. Neither the dose of re-irradiation nor the irradiated surfaces were prognostic factors of local control (P = 0.877 and P = 0.424). Five patients developed radiation-induced pneumonitis without functional respiratory impairment. The incidence of pneumonitis seemed to be related to the biological dose of re-irradiation (P = 0.037). Other late complications occurred such as pigmentation changes (12 pts), telangiectasia (8 pts), chondritis (2 pts), parietal fibrosis (7 pts), rib fractures (4 pts), severe pain (11 pts) and lymphedema (2 pts). The increase in biological equivalent dose was highly statistically linked with the occurrence of disabling pain (P = 0.0123). CONCLUSION: Parietal re-irradiation achieves good and lasting local control with an acceptable rate of acute complications but with a risk of disabling late sequelae such as severe pain.

MRI is now the method of choice for bone marrow imaging. The MR appearance of bone marrow is influenced by the relative amounts of its fatty or hematopoietic components. In the following study, we report different patterns in changes consistent with reconversion into hematopoietic tissue of fatty marrow that were observed in 3 patients who received hematopoietic growth factors in combination with their chemotherapy for musculo-skeletal tumors of lower limbs.

Ectopic breast tissue usually develops along the mammary ridge. The incidence of this anomaly has been reported as high as 6%. Malignant development is rare. A case of carcinoma of aberrant breast tissue, located in the axilla is described. Mammographies of the ectopic breast performed few years before the diagnosis of carcinoma are presented and also those done for the diagnosis of the tumor. A literature study was performed on carcinoma and ectopic breast tissue. Considering high frequence of node involvements for these cases, the optimal therapeutic strategies are discussed.
