Chordoid meningioma is classified in the latest classification of brain tumours as a grade II meningioma, along with large cell meningiomas. It is a rare tumour often associated with systemic symptoms, as described by Castelman. He described a case of chordoid meningioma discovered incidentally in a 45-year-old female patient following road accident. Brain CT scan showed left isodense intradiploid pterional lesion with bone lysis, which was homogeneously enhanced after injection of contrast medium. Magnetic resonance imaging showed T1- hypointense and spontaneously T2 FLAIR hyperintense lesion, which was very strongly enhanced after injection of Gadolinium. Complete resection of the tumour was performed. Histological and immunohistochemical examination showed chordoid meningioma. [ABSTRACT FROM AUTHOR]

Background: retrospective study to elucidate the epidemio-clinical and pathological characteristics, management and evolutional aspects of DFS with comparison with the data of the literature. Procedure: a thirty seven-year study of all cases of DFS. Results: Forty-nine cases of DFS (22 males and 27 females) were diagnosed. Mean age at diagnosis was 48.2 years. The tumor appeared before the age of 15 years in five patients (10%). This was a recurrence in 12% of cases. Five patients reported a history of trauma. The average delay before consultation was 5.6 years. A solitary nodule was the predominant clinical aspect of DFS (59.2%). Mean size was 4.7 cm. The tumor was mainly located on the trunk. The diagnosis of dermatofibrosarcoma protuberans was histologically confirmed in all cases. Immunohistochemical study was achieved in 34 cases and showed positive staining for CD34. The treatment consisted of large surgical excision in all patients. Four patients had revision surgery because of tumor margins. Eight cases (17.4%) presented a local recurrence after a mean delay of 12.5 months. Conclusion: DFS is a low-malignancy potential skin tumor. Treatment of choice is surgery. The main risk is tumor relapse. A long follow-up is then very important to detect it. [ABSTRACT FROM AUTHOR]

Introduction: Desmoplastic fibroma is a rare and benign tumor of the jaws. It is characterized by aggressive local infiltration, and frequent recurrence. Clinical cases: We report clinical observations of 4 patients of different age and sex, who consulted for a mandibular tumor of benign aspect in two cases and malignant aspect in the others. Discussion: Clinically, desmoplastic fibroma has a variable symptomatology. Radiological signs are not specific. Positive diagnosis is based on anatomopathology associated with immunohistochemistry ⪡ immunohistochemistry ⪢. The treatment is surgical. Recurrences will depend on the quality of this treatment.

Abstract: Non-palpable breast cancers are more and more frequent. Their surgical management requires the excision of the tumor and sentinel lymph node (SLN) needing a technical preoperative organization combining preoperative identification of the tumor by wire guide and injection of a radioactive tracer for the identification of SLN. The implementation of this minimally invasive surgery is sometimes paradoxically complicated due to the presurgical organization requiring several medical teams. It is for this reason that hand-held gamma-cameras have been developed, used either preoperatively or during surgery to replace lymphoscintigraphy but also as a help to excision of the tumor after radioisotope injection. The objective of this study was to evaluate the interest of the main hand-held gamma-cameras used in breast cancer. [Copyright &y& Elsevier]

Summary: Introduction: Although fibromatosis is considered as benign tumor, it can have significant morbidity, particularly when it occurs in the head and neck. Their propensity for infiltrative local growth with encroachment on vital structures and their tendency to recur make fibromatoses of the head and neck extremely challenging lesions. Case report: We report the case of a 10-year-old boy with desmoid fibromatosis of the upper lip. For this patient, the medical treatment has been decided to avoid a mutilating surgery. He had a good result with chemotherapy using methotrexate and vinblastine. Discussion: According to the literature, surgery is the most common treatment of fibromatosis in the head and neck region. However, particularly in children, alternative modes of therapy must be considered because of the high recurrence rate and to avoid mutilating operations. Chemotherapy using methotrexate and vinblastine may be a reasonable choice. [ABSTRACT FROM AUTHOR]

Summary: The ovarian masses are rare in pediatric age and are represented primarily by functional cysts and benign tumors; the most common is mature teratoma. Goal: To study the clinical, radiological, and treatment of ovarian tumors in pediatric age. Patients and methods: Retrospective study of 34 cases of tumors and ovarian cysts collected over a period of 16 years, between 1st January 1992 and 30 December 2007 in Pediatric Surgery Department (B) of Children''s Hospital Tunis. Results: The mean age of patients was 7.69 years, with extremes ranging from 1 day to 14 years. In five cases, diagnostic was performed in prenatal period (14.7% of cases). In postnatal, pseudo-surgical table was the most frequent (38.2% of cases). Abdominopelvic ultrasound showed a cystic mass in 53.1% and a heterogeneous mass of tissue type in 28.1% in cases. The treatment was essentially surgery: oophorectomy in 32.3% of cases, a cystectomy in 32.3% of cases, an ovarectomy in 14.7% of cases and cyst puncture in 8.8% of cases. The pathological study found diagnosis of mature teratoma in 35.3% of cases, serous cystadenoma in 23.5% of cases and functional cyst in 26.4% of cases. Conclusion: Ovarian tumors in child are in the majority of mild cases. The diagnostic is based on ultrasound and treatment is usually based on surgical resection, which is preferably carried out by laparoscopic way. [Copyright &y& Elsevier]

Introduction: Papillary carcinomas of the kidney are relatively rare tumors. The purpose of this study was to discuss clinicopathological and imaging features of six cases of papillary carcinoma. Material and methods: In a retrospective study, we studied the clinicopathological and imaging features of six cases of papillary carcinoma retrieved in a 10-years period at the pathology department of F. Hached hospital (Sousse, Tunisia). These tumors were graded according to the new 2004 WHO histopathological classification of renal tumors, on which the prognosis depends. Results: In our study, there were five men and one woman. The median age was 68 years, the tumors were asymptomatic in three cases and revealed by lumbar pain in the other three cases. Treatment consisted of radical nephrectomy in five cases and tumorectomy in one case. The tumors measured 15 to 110 mm. The tumor was multifocal in one case. Histopathological examination found type 1 in 3 cases and type 2 in three cases. Metastases were observed in one case. Conclusion: Renal papillary carcinoma represents a specific group characterized by their less aggressive behaviour. [ABSTRACT FROM AUTHOR]

Abstract: Most of patients with hepatocellular carcinoma (HCC) cannot benefit from surgical therapies. Among nonsurgical options, only radiofrequency can challenge surgery for small size tumours. Conformal radiotherapy is likely highly efficient on solitary tumours, but controlled studies are warranted to conclude. Other options are purely palliative. Transarterial hepatic chemoembolization is the goal-standard for multifocal hepatocellular carcinoma and sorafenib for hepatocellular carcinoma with portal vein invasion, leading to modest but significant benefit on survival rates. Yttrium-90 radioembolization is under evaluation through controlled studies, and could be of major interest for multifocal hepatocellular carcinoma with or without portal venous invasion.

Abstract: Epithelioid sarcoma is a rare soft-tissue sarcoma affecting mostly young adult males. It is exceptional under the age of 20. Diagnosis is by histiochemistry. Treatment is mainly wide surgical excision. The normal evolution is local spread followed by generalized metastasis. We report a case of epithelioid sarcoma of the left arm in a 16-year old adolescent of 8 months duration. [Copyright &y& Elsevier]

Summary: An echogenic tumor (22×22mm) isolated from the anterior part of the left leg at 27 WA of pregnancy suggested an angiomatous structure. This mass appeared to be well vascularized on Doppler examination. Three-dimensional imaging showed connections with adjacent tissues. The limbs were mobile. Delivery of a 3990-g-boy occurred normally. On the anterior part of the left leg, there was a plate-shaped mass with a pink hole at the superior part. Excision under general anesthesia was performed at the first month because of the risk of rupture and bleeding. The dissection was easy with the deep plane. Healing was complete 10 days after the surgical procedure and the aesthetic aspect was good 1 year later. Histological findings of the suspect mass emphasize the vascular aspect of the tumor. A hemangioma capillary with venous structures in the dermal hypodermic area was found. [Copyright &y& Elsevier]

Summary: Inflammatory myofibroblastic tumours (IMTs) are clinical and pathological distinct entities with controversial biological entities. IMTs have been described in the lungs, abdomen, retroperitoneum and extremities but rarely in the head and neck region. This case report corresponds to an IMT of the nose and the paranasal sinuses in a little girl of 7 years of age. The computed tomography scan showed an expanding tumoral process without skull destruction. First case report in the west African region, this observation describes the treatment instituted according to the possible care in our medical area, and the treatment when the patient was referred to a centre with efficient technical platform. This case underlines the aggressiveness of this type of tumour: an invasive tumour with local-regional extension and high recurrence potential. Currently, after 2 years, the tumoral process is considered cured after several radical surgical excisions. [Copyright &y& Elsevier]

Summary: Merkel cell carcinoma is a cutaneous-neuroendocrine tumor, which may be difficult to diagnose and to treat. Objective: The objective of this study was to analyse the treatment and the recurrences of Merkel cell carcinoma. Patients and methods: A retrospective study was performed on the patients operated of a Merkel cell carcinoma between 1994 and 2004. Clinical data of the patients and the tumor, treatment (surgery and radiotherapy) and recurrences were entered in a database. Results: Twenty-four patients were operated (8 men and 16 women). The mean age at diagnosis was 71.5 years. The average follow-up was 30.8 months. The treatment was a large surgical removal of the tumor with immediate closure, systematically followed by radiotherapy. There were five recurrences and no death. Conclusion: Merkel cell carcinoma is an aggressive tumor. Immediate closure after large surgical removal allows radiotherapy. [Copyright &y& Elsevier]

Summary: Pilomatrixoma is a benign skin neoplasm of the hair follicle. It''s common in the pediatric population. It''s usually misdiagnosed and confused with other skin lesions. Head and neck represent the usual locations. The extremity remains an exceptional location. Through an observation of a pilomatrixoma of the leg in an adult patient treated surgically without recurrence, different diagnostic and therapeutic aspects of this pathology will be recalled.

Summary: Background: Glomus tumor is a neuromyoarteriel benign hamartoma. It is a relatively uncommon lesion. The aim of this study is to define all the unusual localizations of glomus tumor. Patients and methods: From January 1999 to December 2006, we included in this retrospective study all patients who had the classic triad of symptoms with histological exam. We analysed epidemiological, clinical and therapeutical features of our patients. Results: Fourteen patients were found to have histopathologically-proven glomus tumors. The patients, eight men and six women, had mean of age around 42 years. Three unusual locations were founds: forearm, sacred region and parasternal. Most glomus tumors occur in the toes and fingertips. They are difficult to diagnose, despite painful symptom, because of their unusual locations. Conclusion: Glomus tumors are rare vascular tumors. The usual presentation is a solitary nodule in the distal portion of a digit, but can also occur wherever, with localizations unaccustomed and disconcerting. [Copyright &y& Elsevier]

Summary: The solitary fibrous tumor is a rare tumor, ubiquitous, mesenchymatous essentially affecting serosal surfaces. The location in the scalp is exceptional. We report a case of tumor in left occipital scalp discovered after recurrence of a tumor initially taken for a lipoma. The motive for consultation was mainly aesthetic. The pathological examination is the main element of diagnosis. The assumption is based on a large lumpectomy and an extended and regular clinical monitoring. The forecast is favourable with a decline of one year. However, relapses may occur in the long-term and there are malignant forms. [Copyright &y& Elsevier]

Summary: Subject: Our report concerns a large intermammary cutaneous Abrikossoff tumor on a 41-year-old female patient, which has prompted us to review the literature. Case: It was a low presternal skin tumor; CT-Scanning showed a homogeneous mass 5cm high, 4cm wide and 4cm deep. Total tumoral included the right pectoralis major muscle aponevrosis. The skin defect was closed using a V–Y local plasty. Histologial examination revealed no sign of malignity. Discussion: Abrikossoff tumors (or granular cell tumors) are rare ubiquitary tumors locating preferably in ENT and bucal cavity mucosa. They develop between 20 and 60 and more often concern women. They are overwhelmingly single and benign but on occasion multifocal or malignant. Immunohistochemistry points to a schwannian origin. Treatement is exclusively surgical. Skin closure is by direct suture, skin grafting or local plasty. The use of flaps is not advised as it may delay local recidivation diagnosis. The literature reports one single other case of chest wall location. Conclusion: Abrikossoff tumors require complete exeresis and mandatory histological examination into possible signs of malignity. The risk of recidivation warrants long-term surveillance. [Copyright &y& Elsevier]

Summary: We report the first case of malignant solitary fibrous tumor of the abdominal wall in a man. Immunohistochemical staining for CD34 and bcl-2 were positive. Surprisingly, estrogen and progesterone receptors were focally positive. Expression of steroid hormone receptor in solitary fibrous tumor was rarely reported in the literature. In a few series, these receptors were identified as a risk factor of recurrences after surgical excision. Six months after complete surgical resection of the mass, our patient has been quite well without any evidence of recurrence. [Copyright &y& Elsevier]

Abstract: Esophageal cancer is characterized by various degrees of lymph node invasion and metastasis, both of which are associated with a poor prognosis. Exclusive concomitant radiochemotherapy (RCT) at a dose of 50 Gy delivered over 25 sessions, according to the RTOG 85-01 protocol, has led to improved five-year survival in 25% of patients, whereas no patients survive for five years using radiotherapy alone. Surgery, even when combined with preoperative RCT, also gives disappointing results for locally advanced tumors, which casts serious doubts on the usefulness of preoperative radiotherapy. By varying the fractionation schedule, the length of treatment or the radiotherapy volumes, it has become possible to obtain levels of locoregional relapse of around 35 to 45%. The increasing incidence of adenocarcinoma, which differs from epidermoid cancer with regard to the degree of lymph node invasion, has revived discussion on radiotherapy volumes. Given this difference between these two histological forms, we propose here a number of recommendations concerning radiotherapy volumes for patients presenting with cancer of the esophagus. Finally, analysis of the results for locoregional relapse according to the dose of radiation and the recommended radiotherapy volumes, has led us to investigate why increasing the dose of radiation has no impact in esophageal cancers.

Abstract: FDG-(18F) PET can now be usually included in the treatment strategy of esophageal cancers for the pretreatment staging in operable tumours or for the diagnosis of recurrence. PET is also a good tool in conformal radiation therapy for improving the target coverage to treat the metabolic target volume or the biological target volume. Furthermore, PET seems to be interesting for evaluation of tumour response and could modify the treatment strategy after neoadjuvant chemotherapy or concurrent chemotherapy and radiation therapy. New radiotracers could allow advances in biological and molecular tumour delineation and contribute to change in treatment strategy based on functional and biological imaging.

Abstract: Nasopharyngeal angiofibroma is a locally aggressive, although histologically benign, vascular neoplasm. This neoplasm accounts for 0.05% of head and neck tumours and affects almost exclusively male adolescents. Surgery is considered as the primary treatment of nasopharyngeal angiofibroma. Other treatment modalities such as radiotherapy and chemotherapy are still recommended for intracranial extension involving the cavernous sinus or the internal carotid artery. We report a rare case of nasopharyngeal angiofibroma, further complicated with a Kennedy syndrome in a 34 year-old women. The treatment consisted in a chemotherapy (adriamycine, decarbazine) followed by radiotherapy. We discuss the relevance and outcome of the association chemotherapy–radiotherapy in the treatment of nasopharyngeal angiofibromas with a consistent intracranial extension (stage III B of Arch Otolaryngol Head Neck Surg 122 (2003) 122–129).

Brenner tumors account for only 1 to 2% of ovarian tumors. Proliferating Brenner tumors are characterized by an epithelial proliferation, resembling superficial well-differentiated urothelial carcinomas. A single 29-year-old patient was operated on for an ovarian tumor. On gross examination, the tumor, which originated in the left ovary, was cystic multilocular and presented polyoid excrescences. A definitive histological exam showed a papillary proliferation lined by transitional cells without stroma infiltration. Mucinous cells lined some cavities. The diagnosis of proliferating Brenner tumor was made. Clinical and pathological characteristics of this rare entity will be discussed. [Copyright &y& Elsevier]

Ovarian cancer represents 4500 new cases a year in France and the prognosis of such tumor is not yet clear, even for the early stages. This is notably owing to the amount and size of peritoneal tumor residual. Recently, five therapeutic trials were published concerning the intra-peritoneal chemotherapy of ovarian cancer stage III in patients to whom an optimal debulking surgery had been done. These studies were variable in there outcome showing on the one hand, either the absence of significant difference or a significant lengthening of both total life duration and life without recurrence during the period of treatment with intra-peritoneal chemotherapy. On the other hand, there was a significant increase in hematological toxicity and temporary impairment of the quality of life during intra-peritoneal treatments. There were also complications linked to the intra-peritoneal catheter, which led to the termination of the treatment protocol in some cases. However, results showed a mattering benefit of survival in spite of a notable rate of incomplete treatment protocols. These results have demonstrated the necessity to consider the intra-peritoneal adjuvant chemotherapy as a treatment option in patients with epithelial ovarian cancer stage III. Patients must be highly selected and well counseled, in order to go for this treatment option after receiving optimal debulking surgeries. [Copyright &y& Elsevier]

We report a case of a vulvar invasive squamous cell carcinoma associated to a benign tumor with apocrine differenciation, the hidradenoma papilliferum, infiltrated by the carcinoma. Diagnosis was established by clinical and histopathological examination, first on biopsy and then on local vulvar excision. Classical association between hidradenoma papilliferum and Paget's disease is described, but to the best of our knowledge, there have been no previous reports of such case in published literature. A common physiopathological etiology cannot be completely excluded. [Copyright &y& Elsevier]

Abstract: Good results obtained by the team from Boston increased the interest in pleuropneumonectomy for mesothelioma. Adjuvant high-dose hemithoracic radiation after surgical resection decreased the local recurrence rate from 35 to 13%. The high rate of peritoneal (26–31%), controlateral pleural and pericardial recurrences justify the routine practice of preoperative laparoscopy and controlateral thoracoscopy and a pleuropneumonectomy without pericardotomy and diaphragmatic resection. The diaphragm is lowered to facilitate radiotherapy. Chemotherapy may be performed postoperatively. [Copyright &y& Elsevier]

Abstract: The presence of positive surgical margins on radical prostatectomy specimen is an adverse prognostic factor. Parameters supposed to influence surgical margin status includes pathology method analysis, surgical technique, tumoural and non tumoural patient parameters, and neoadjuvant hormonal therapy. Regarding the surgical technique, surgeon''s experience and neuro-vascular bundles preservation are the most important factors of margin status, whereas surgical approach, bladder neck conservation, intraoperative frozen analysis, and bleeding are minor factors. Non tumoural patient parameters influencing surgical margin status include patient''s age and weight, and prostate gland weight. For tumoural parameters, pathological stage and tumour volume are more important factors than the tumour grade and PSA. Five preoperative tumoural risk factors of positive surgical margins are particularly important, including abnormal digital rectal examination, preoperative PSA>10ng/mL, biopsy Gleason score ≥7, number of positive biopsy cores≥2, and suspicion of extraprostatic extension on radical prostatectomy specimen.

Abstract: Mesenteric panniculitis also named retractile mesenterite is a rare tumor-like lesion that thickens and shortens the mesentery. It is characterized by the association of inflammation, necrosis or fibrosis involving the adipose tissue of the bowel mesentery. The pathophysiology of this disease remains unclear despite associations with inflammatory diseases or malignancies, especially lymphomas that have been described. When symptomatic, patients may present with abdominal pain, palpable abdominal mass or intestinal obstruction. The disease remains asymptomatic in 30 to 50% of cases. Abdominal CT plays an important role in suggesting the diagnosis and can be useful in distinguishing the several conditions that can mimic mesenteric panniculitis. Nevertheless, pathologic examination of surgical excisional biopsies or sometimes percutaneous biopsies remains necessary to confirm the diagnosis and exclude an underlying infection or malignancy. Medical treatment may consist of therapy with anti inflammatory or immunosuppressive agents and can be proposed in highly symptomatic diseases. Surgical treatment should be exclusively attempted when intestinal obstruction or ischemia occur. Most of the time, it consists in intestinal derivation or segmental resection because complete excision of the lesions is often not possible. Mesenteric panniculitis usually has an uneventful clinical course and resolves spontaneously in a variable delay. [Copyright &y& Elsevier]

Life expectancy regularly increases while breast cancer frequency reaches a maximum between 60 and 70 years. The referent treatment for elderly women presenting with localized breast tumor remains the association of tumorectomy and axillary dissection followed by breast irradiation. Due to some comorbidity associated factors, this adjuvant radiation therapy delivering 50 Gy/25 fractions/5 weeks appears sometimes difficult to achieve. Partial and accelerated irradiation of the breast allows not only to increase the local control rate but also to complete this adjuvant treatment in 5 to 8 days. Avoiding numerous and expensive transportations, this therapeutic approach for elderly women could lead to an improved quality of life and maybe a decrease in cost of treatment.

Treatment of the peritoneal carcinomatosis (PC) with a curative intent has improved during the last 15 years. It combines maximal cytoreductive surgery (resecting all tumour seeding greater than 1 mm) to treat the macroscopic disease, with intraoperative chemohyperthermia to treat the remaining microscopic disease. The techniques of peritonectomy are specific and are performed only if all the macroscopic disease is resected and if it results in a satisfying quality of life for the patient. In order to be efficient, the techniques of chemohyperthermia need strict quality control. With these conditions, surgery plus intraperitoneal chemohyperthermia results in curing the peritoneal disease in two-thirds of the patients with colorectal cancer and in three-quarters of patients with peritoneal pseudomyxoma. However, it is currently not efficient for PC originating from gastric and small bowel adenocarcinomas. [ABSTRACT FROM AUTHOR]

The prognosis of borderline ovarian tumors (BOT) is globally excellent and surgery is the cornerstone of treatment. The place of post-operative treatment in BOT remains complex and controversial in some situations. Only a small subset of patients with poor prognostic factors may benefit from chemotherapy, but these factors (clinical, biological or histologic) are yet to be clearly defined. Responses to chemotherapy have been reported in some invasive implants or for bulky disease, but the overall benefit for the patients is not clear (survival, quality of life, treatment toxicity). Some authors propose adjuvant treatment only for patients with invasive implants, and others only in the case of aneuploid invasive implants. The question, therefore, remains open: can some patients with BOT benefit from adjuvant chemotherapy? [ABSTRACT FROM AUTHOR]

Abstract: This retrospective study aims. – To define a clinical and secretory profile of paragangliomas extra-adrenal chromaffin tumors. Methods. – From 1971 throughout 2002, 39 paragangliomas have been observed in 38 patients (22 male, 16 female, average age 41,2 years). Results. – Four were located above the diaphragm, 35 were sub-phrenic (6 of the organ of Zuckerkandl), 32 secreted catecholamines, 23 were hypertensive (with only one without hypersecretion of catecholamines). Among 29 131I-metaiodobenzylguanidine scans (MIBG) reviewed, 20 tumors took up the radiopharmaceutical. The treatment was surgical in 35 cases with addition of external radiotherapy and MIBG in one case each; two patients died before any treatment. Two patients with persistent disease after surgery were successfully treated by surgery or MIBG. Histologically, 20 were malignant and 17 were seemingly benign. All exclusive dopamine secreting paragangliomas were malignant. Six patients relapsed two of which for a tumor initially classified as benign. The treatment of recurrences was surgical, by MIBG or by external radiotherapy. Nine patients had a family history of chromaffin tumor(s). The genetic survey made in five of these nine patients was positive in all cases. [Copyright &y& Elsevier]

Fresh allografts of bone are commonly used for repairing small defects, but preserved grafts are required for replacing large sections of long bones. We have collected these grafts in sterile conditions and then preserved the specimens in liquid nitrogen at minus 196 degrees Celsius. Biological, histological and biomechanical studies have confirmed the value of this technique. The method preserves the normal architecture of bone and viable cartilage cells. The medullary cells are gradually destroyed in situ leaving a protein matrix to which mineral components are fixed. Neither of these are antigenic in allografts and immunological problems are rarely encountered. When the recipient site is well vascularised the graft becomes fully integrated within two or three years. Doubt has been expressed as to the functional viability of the cartilage in large allograft joint replacements, and is has been suggested that metal prostheses might be better. Research is in progress in the use of ligament allografts and on the use of bank bone with large prostheses. The functional results are satisfactory in more than 90% of patients treated with these large allografts. [ABSTRACT FROM AUTHOR]

Abstract: The schwannoma is a benign tumour that can be eradicated; it usually occurs in the peripheral nerves of the upper limb. We report an exceptional localization in the axillary nerve. The diagnosis is based on the typical MRI appearance: in addition, confirmation of the diagnosis has to be made by histological examination. The surgical treatment by resection, taking care to preserve adjacent nerve fibres. This allows recovery without any after-effects since the recurrence rate as well as the potential for malignant transformation of this type of tumour is low. [Copyright &y& Elsevier]

But: Les tumeurs pseudo-papillaires du pancréas sont rares et ont un potentiel malin faible, mais elles ont parfois une agressivité locale importante. Le but de ce travail était d’évaluer le risque évolutif en cas de résection incomplète de la tumeur. Matériel et Méthodes: Nous avons contacté tous les auteurs qui ont publié un cas avec résection incomplète entre 1985 et 2008, afin de connaitre le suivit a beaucoup plus long terme de ces patients. Résultats: Nous avons pu connaitre le suivit de 11 patients sur les 18 publiés, et la médiane de survie pour ceux ci a été de 69,5 mois (5,7 ans). Conclusion: Du fait d’un développement essentiellement chez des adolescents et des femmes jeunes, une médiane de survie de 5,7 ans n’est pas acceptable. En cas d’envahissement local d’une tumeur de Frant’z, une résection large passant à distance de la lésion doit toujours être tentée, même au prix d’une chirurgie parfois mutilante… [ABSTRACT FROM AUTHOR]

Abstract: The recent development of awake surgery in neuro-oncology allowed a conceptual change, i.e. the realization of resection for invasive brain tumors according to functional and not anatomic boundaries. This paradigmatic shift enabled a significant improvement of results in surgery for gliomas, by opening the door to resections within eloquent areas classically considered as “inoperable”, while preserving and even improving the quality of life of patients. In addition, the extent of resections has been maximized, leading to an increase of median survival – especially in low-grade gliomas. Strong relationships between the different teams (surgeons, neuropsychologists, anaesthesiologists) are crucial for the development and improvement of awake surgery. Thus, it seems important that anesthesiologists can benefit from a clear and accurate knowledge of the real contribution of this procedure, in order to better evaluate the balance between the theoretical risks of surgery under local anesthesia versus the actual risk of not performing resection with a maximum of safety and efficiency for the patients. The purpose of this plea is to advocate the spread of awake surgery in routine practice, due to its major impact on both functional and survival outcomes, by nonetheless keeping in mind that a multidisciplinary staff is mandatory for selection of patients as well as into the operating room. In this state of mind, anaesthesiologists have to play a central role, through an increased involvement in this field. [Copyright &y& Elsevier]
