BACKGROUND: The purpose of the present study was to analyze long-term survival and disease-free survival after liver resection for giant hepatocellular carcinoma (HCC) ≥ 10 cm compared to HCC < 10 cm in diameter. The surgical approach in the treatment of giant HCC may achieve long-term survival and disease-free survival comparable to treatment of smaller lesions. METHODS: This retrospective analysis was a monocentric study conducted in a tertiary university center. It included 101 patients from 114 consecutive liver resections for HCC, separated into two groups: those with tumors less than 10 cm in diameter (small HCC; n = 79) and those with tumors larger than 10 cm (giant HCC; n = 22). The main outcome measures were overall five-year survival, five-year disease-free survival, recurrence rate, perioperative mortality at 30 days, surgical complication rate, and re-intervention rate. RESULTS: The two groups were homogeneously distributed, apart from cirrhosis, which was found more frequently in the group with small HCC (77 vs. 41 %; p = 0.0013). Both median survival (24 vs. 27 months; p = 0.0085) and overall 5-year survival (21 vs. 45; p = 0.04) were significantly poorer in the small HCC group compared to the giant HCC group. There were no differences en terms of recurrence rate, pattern, and timing. CONCLUSIONS: Liver resection for HCC larger than 10 cm is a valuable option in selected patients, one that provides overall survival and disease-free survival comparable to smaller lesions. Functional reserves of the liver, more than the size of the lesion, may be important in patient selection for surgical resection.

We report 4 patients with stage IVA thymic tumors who underwent extrapleural pneumonectomy and thymectomy with venous confluence resection using a temporary percutaneous venous jugular-femoral bypass technique. The superior vena cava was replaced in 2 patients, and the innominate vein was resected in 2 patients. Complete tumor resection was obtained in all patients. There was no 90-day postoperative mortality. One patient died at 6 months postoperatively of an unrelated cause, without recurrent disease, and 3 are alive and disease-free with a follow-up ranging from 19 to 80 months. Extrapleural pneumonectomy can be combined with thymectomy and venous confluence resection for stage IVA thymic tumors.

O. Lebeau, C. Van Delden, J. Garbino, J. Robert, F. Lamoth, J. Passweg, Y. Chalandon. Disseminated Rhizopus microsporus infection cured by salvage allogeneic hematopoietic stem cell transplantation, antifungal combination therapy, and surgical resection. Transpl Infect Dis 2010. All rights reserved Abstract: Invasive Zygomycetes infection complicating prolonged neutropenia is associated with high mortality in the absence of immune recovery. We report a patient who developed disseminated zygomycosis due to Rhizopus microsporus during induction chemotherapy for acute myeloid leukemia. Rescue allogeneic hematopoietic stem cell transplantation (allo-HSCT) was performed as her only chance of cure of this infection and to treat refractory leukemia. Posaconazole combined with liposomal amphotericin B contained the zygomycosis during prolonged neutropenia due to allo-HSCT followed by intense immunosuppression for grade IV acute graft-versus-host disease. Surgical removal of all infected sites after immune recovery, with prolonged posaconazole treatment, ultimately cured the infection. New combination antifungal therapies might sufficiently control disseminated zygomycosis to allow allo-HSCT to be performed, assuring life-saving immune recovery. Surgery appears to be necessary for definite cure of these infections.

Pre-operative assessment and surgical management of patients with non-lesional extratemporal epilepsy remain challenging due to a lack of precise localisation of the epileptic zone. In most cases, invasive recording with depth or subdural electrodes is required. Here, we describe the case of 6.5-year-old girl who underwent comprehensive non-invasive phase I video-EEG investigation for drug-resistant epilepsy, including electric source and nuclear imaging. Left operculo-insular epilepsy was diagnosed. Post-operatively, she developed aphasia which resolved within one year, corroborating the notion of enhanced language plasticity in children. The patient remained seizure-free for more than three years.

Résumé : Objectif: Analyse d'un traitement de chimiothérapie à base de cisplatine de type néoadjuvant en comparaison à un traitement de radio-chimiothérapie suivi de la résection chirurgicale chez des patients présentant un carcinome pulmonaire non à petites cellules de stade Ill (N2) prouvé histologiquement par médiastinoscopie. Evaluation de la morbidité postopératoire, du down-staging ganglionnaire, des taux de survie globale et sans récidive ainsi que du site de récidive. Matériel et méthodes : 82 patients ont été inclus dans l'étude entre Janvier 1994 et Juin 2003, parmi eux 36 ont été traités avec une chimiothérapie néoadjuvante à base de cisplatine et doxétacel (groupe l). Les autres 46 patients ont été soumis à une radio-chimiothérapie néoadjuvante avec administration de 44 Gy (groupe II), soit de façon séquentielle (25 cas) soit concomitante (21 cas). Dans tous les cas des métastases à distance ont été exclues par une évaluation préopératoire comprenant une scintigraphie osseuse, un Ct scan thoraco-abdominal, ou un examen PET scan ainsi qu'une IRM cérébrale. La médiastinoscopie effectuée avant le traitement d'induction chez la totalité des patients, de même que la résection chirurgicale de la tumeur pulmonaire et la lymphadenectomie médiastinale ont été effectuées par le même chirurgien. Résultats : La tumeur pulmonaire était de stade Ti à T2 dans respectivement 47% et 28% des patients des groupes (e II, T3 dans 45% et 41% et T4 dans 8% et 31% des cas. Le type de résection effectué (lobectomie, lobectomie en manchon, pneumonectomie) était comparable dans les deux collectifs (p=0.03) Le taux de mortalité postopératoire à 90 jours était de respectivement 3% et 4 "Vo (p=0.6). Une résection complète (RO) a pu être obtenue dans 92% et 94% des cas (p=0.6) avec un downstaging ganglionnaire médiastinal dans 61% et 78% des patients respectivement (p<0.001). Les taux de survie globale à 5 ans et de survie sans récidive à 5 ans s'élevaient à 40% et à 36% respectivement, sans différence significative entre des tumeurs de stade Ti à T3 et T4. Le taux de survie globale n'était pas significativement différent entre les deux modalités de traitement d'induction, toutefois après radio-chimiothérapie on observait une plus longue survie sans récidive (p.0.04). Il n'y avait par ailleurs pas de différence significative, en termes de morbidité post-opératoire, résecabilité, downstaging ganglionnaire, survie globale et sans récidive, entre les patients traités par radio-chimiothérapie séquentielle ou concomitante. Conclusions : En cas de carcinome pulmonaire non à petites cellules de stade III (N2) un traitement d'induction par radio chimiothérapie suivi de la résection chirurgicale est associé avec un meilleur downstaqing médiastinal ainsi qu'une plus longue survie sans récidive en comparaison au traitement d'induction par chimiothérapie seule. Abstract : Objective: Comparison of prospectively treated patients with neoadjuvant cisplatin-based chemotherapy vs radiochemotherapy followed by resection for mediastinoscopically proven stage III NZ non-small cell lung cancer with respect to postoperative morbidity, pathological nodal downstaging, overall and disease-free survival, and site of recurrence. Methods: Eighty-two patients were enrolled between January 1994 to June 2003, 36 had cisplatin and doxetacel-based chemotherapy (group I) and 46 cisplatin-based radiochemotherapy up to 44 Gy (group II), either as sequential (25 patients) or concomitant (21 patients) treatment. All patients had evaluation of absence of distant metastases by bone scintigraphy, thoracoabdominal CT scan or PET scan, and brain MRI, and all underwent pre-induction mediastinoscopy, resection and mediastinal lymph node dissection by the same surgeon. Results: Group I and II comprised T1/2 tumors in 47 and 28%, 13 tumors in 45 and 41%, and 14 tumors in 8 and 31% of the patients, respectively (P=0.03). There was a similar distribution of the extent of resection (lobectomy, sleeve lobectomy, left and right pneumonectomy) in both groups (P=0.9). Group I and II revealed a postoperative 90-d mortality of 3 and 4% (P=0.6), a RO-resection rate of 92 and 94% (P=0.9), and a pathological mediastinal downstaging in 61 and 78% of the patients (P<0.01), respectively. 5y-overall survival and disease-free survival of all patients were 40 and 36%, respectively, without significant difference between T1-3 and T4 tumors. There was no significant difference in overall survival rate in either induction regimens, however, radiochemotherapy was associated with a longer disease-free survival than chemotherapy (P=0.04). There was no significant difference between concurrent vs sequential radiochemotherapy with respect to postoperative morbidity, resectability, pathological nodal downstaging, survival and disease-free survival. Conclusions: Neoadjuvant cisplatin-based radiochemotherapy was associated with a similar postoperative mortality, an increased pathological nodal downstaging and a better disease-free survival as compared to cisplatin doxetacel-based chemotherapy in patients with stage III (N2) NSCLC although a higher number of 14 tumors were admitted to radiochemotherapy.

The aim of this study was to determine the influence of comorbidity on outcome after pulmonary resection in patients over 75 years old. Three hundred and thirty-three patients with non-small-cell lung cancer operated on between 1998 and 2002 were divided into 3 age groups: < 60 years (group 1), 60-75 years (group 2), > 75 years (group 3). Overall operative mortality was 0.3%; 30-day mortality was 1%. There were more major complications with re-operation in groups 1 and 2, but minor complications occurred significantly more frequently in group 3 (36% vs 16%). Overall mean hospital stay was 12 days, with no significant difference among groups. Three-year survival rates were: 80%, 70%, and 65% in groups 1, 2, and 3, respectively, with no significant difference among groups. Age or the presence of comorbidity should not be considered contraindications for lung resection. With proper patient selection and careful preoperative evaluation, many major complications after pneumonectomy are avoidable.

Background: About 80% of patients with Crohn's disease (CD) require bowel resection and up to 65% will undergo a second resection within 10 years. This study reports clinical risk factors for resection surgery (RS) and repeat RS. Methods: Retrospective cohort study, using data from patients included in the Swiss Inflammatory Bowel Disease Cohort. Cox regression analyses were performed to estimate rates of initial and repeated RS. Results: Out of 1,138 CD cohort patients, 417 (36.6%) had already undergone RS at the time of inclusion. Kaplan-Meier curves showed that the probability of being free of RS was 65% after 10 years, 42% after 20 years, and 23% after 40 years. Perianal involvement (PA) did not modify this probability to a significant extent. The main adjusted risk factors for RS were smoking at diagnosis (hazard ratio (HR) = 1.33; p = 0.006), stricturing with vs. without PA (HR = 4.91 vs. 4.11; p < 0.001) or penetrating disease with vs. without PA (HR = 3.53 vs. 4.58; p < 0.001). The risk factor for repeat RS was penetrating disease with vs. without PA (HR = 3.17 vs. 2.24; p < 0.05). Conclusion: The risk of RS was confirmed to be very high for CD in our cohort. Smoking status at diagnosis, but mostly penetrating and stricturing diseases increase the risk of RS.

White-light cystoscopy and cytology are the standard tools to diagnose bladder cancer. White-light cystoscopy is excellent to detect macroscopic exophytic tumors, but its sensitivity is poor for flat tumors such as carcinoma in situ. Use of fluorescence cystoscopy during transurethral bladder resection improve tumor detection, particulary for carcinoma in situ. Fluorescence cystoscopy reduce residual tumor rate, especially for voluminous and multifocal tumors with consecutive lower recurrence. Fluorescence is now recommended to diagnose and treat bladder cancer.

Introduction: Surgery represents the treatment of choice for localized renal cell neoplasia. Partial nephrectomy (PN) has widened its indications over the past two decades and has shown oncological results equivalent to radical nephrectomy for small tumors. The role of negative surgical margins has been widely debated. Intraoperative fresh frozen section analysis is shown to be unreliable, expensive, time-consuming and not well correlated to final pathology. The goal of the present study was to assess the feasibility of intraoperative ex-vivo ultrasound (US) control of resection margins and its correlation to margin status at definitive pathology in patients undergoing PN.Material and Methods: The study was carried out in our institution from February 2008 to March 2010. Patients undergoing PN for T1-T2 renal tumors were included. Ex vivo US was performed by one single senior radiologist. Considering its availability, not all consecutive eligible patients were included. PN was undertaken in a standardized technique applying the "minimal healthy tissue margin" technique. Once resected, the specimen was kept in a saline solution and ex-vivo US was performed to evaluate the whole tumor pseudocapsule.Results: Twelve patients (five women, age (mean}SD) 65}11 years) were included. Intraoperative ex-vivo US showed negative surgical margin in all cases. US duration ranged from 1 to 4 minutes, with a median time of 1 minute. Definitive histological analysis confirmed the presence of two angiomyolipoma, eight pT1a tumors, of which seven were clear cell carcinoma and one was a type II papillary tumor, one pT1b clear cell carcinoma and one pT2 chromophobe carcinoma (size 2.9}2.3 cm). Final pathology revealed R0 margins.Conclusion: Intraoperative ex-vivo US control of resection margins in patients undergoing PN is feasible, time-efficient and well correlated to definitive pathological examination with regards to margin status.

PURPOSE: To analyze outcomes after right portal vein embolization extended to segment IV (right PVE + IV) before extended right hepatectomy, including liver hypertrophy, resection rates, and complications after embolization and resection, and to assess differences in outcomes with two different particulate embolic agents. MATERIALS AND METHODS: Between 1998 and 2004, transhepatic ipsilateral right PVE + IV with particles and coils was performed in 44 patients with malignant hepatobiliary disease, including metastases (n = 24), biliary cancer (n = 14), and hepatocellular carcinoma (n = 6). Right PVE + IV was considered if the future liver remnant (FLR; segments II/III with or without I) was less than 25% of the total estimated liver volume (TELV). Tris-acryl microspheres (100-700 microm; n = 21) or polyvinyl alcohol (PVA) particles (355-1,000 microm; n = 23) were administered in a stepwise fashion. Smaller particles were used to occlude distal branches, followed by larger particles to occlude proximal branches until near-complete stasis. Coils were then placed in secondary portal branches. Computed tomographic volumetry was performed before and 3-4 weeks after right PVE + IV to assess FLR hypertrophy. Liver volumes and postembolization and postoperative outcomes were measured. RESULTS: After right PVE + IV with PVA particles, FLR volume increased 45.5% +/- 40.9% and FLR/TELV ratio increased 6.9% +/- 5.6%. After right PVE + IV with tris-acryl microspheres, FLR volume increased 69.0% +/- 30.7% and FLR/TELV ratio increased 9.7% +/- 3.3%. Differences in FLR volume (P = .0011), FLR/TELV ratio (P = .027), and resection rates (P = .02) were statistically significant. Seventy-one percent of patients underwent extended right hepatectomy (86% after receiving tris-acryl microspheres, 57% after receiving PVA). Thirteen patients (29%) did not undergo resection (extrahepatic spread [n = 9], inadequate hypertrophy [n = 3], other reasons [n = 1]). No patient developed postembolization syndrome or progressive liver insufficiency after embolization or resection. One death after resection occurred as a result of sepsis and hemorrhage. Median hospital stays were 1 day after right PVE + IV and 7 days after resection. CONCLUSION: Transhepatic ipsilateral right PVE + IV with use of particles and coils is a safe, effective method for inducing contralateral hypertrophy before extended right hepatectomy. Embolization with small spherical particles provides improved hypertrophy and resection rates compared with larger, nonspherical particles.

Whether maximal surgical resection of glioblastoma improves patient survival has been controversial, as it is difficult to perform an unbiased assessment of extent of resection (EOR) independent of other patient-specific prognostic factors. Recently, glioblastoma has been sub-classified into 4 distinct molecular risk groups (RGs), which have been validated as prognostic biomarkers in the randomized clinical trial of temozolomide dosing in glioblastoma: the Radiation Therapy Oncology Group 0525 (RTOG-0525) trial. We sought to perform exploratory analyses examining gross total resection (GTR) versus sub-total resection (STR) within these RGs in RTOG-0525 patients. Across all randomized patients, n ¼ 354 had STR and n ¼ 450 had GTR as determined by neurosurgeon operative report. GTR was not significantly associated with survival across the overall study group. A total of 725 patients had sufficient tissue for determination of molecular RG. There were no significant differences in percentage of GTR between each of the 4 RGs (P ¼ 0.64). In exploratory subgroup analyses, GTR was associated with improved survival only for patients with tumors from RG4. Hazard ratios (95% confidence intervals) were 0.52 (0.08-2.07) for RG1 (n ¼ 28, 68% GTR), 1.74 (0.75-4.05) for RG2 (n ¼ 39, 56% GTR), 1.09 (0.84-1.42) for RG3 (n ¼ 284, 56% GTR), and 1.26 (1.01-1.56) for RG4 (n ¼ 374, 55% GTR). In univariate analysis within RG4, GTR was associated with a median survival of 14.6 months vs 12.7 months for STR (P ¼ 0.0352. In a Cox model adjusting for age, KPS, and neurologic function (NF), surgery remained an independent factor within RG4: GTR (P ¼ 0.0331), age (P ¼ 0.0014), KPS (P ¼ .3289), and NF (P ¼ 0.3804). There are important cautions in the interpretation of these data, including lack of MRI confirmation of EOR, and inclusion of a range of STR (from biopsy to near-total resection). However, these exploratory results raise the possibility that upfront characterization of tumor molecular profile may allow for personalized therapeutic strategies to improve outcomes for patients with glioblastoma.

Introduction: Enchondromas are among the most current benign bone tumours. Malignant degeneration is extremely rare (<1%) and generally presents as a low grade chondrosarcoma. For localized grade 1 lesions, the treatment of choice is curettage. Wide excision and reconstruction is generally not necessary, unless locally advanced or more aggressive behaviour is suspected at presentation. Case report: A healthy 72 yo male presented with pain and recurrent knee joint effusion. X-rays show a classical central distal metaphyseal enchondroma of the femur associated with subtle osteolysis of the lateral condyle. MRI confirms the presence of a locally aggressive chondromatous lesion based in a classical enchondroma. Core needle biopsy revealed a grade 1 chondrosarcoma, which was in contrast to the radiological aggressiveness of the lesion. Total body CT-scan did not reveal metastatic disease. A wide resection was planned, as a high-grade lesion and joint contamination was suspected. We performed an extra-articular knee resection and reconstruction with a hinged modular total knee megaprosthesis. The definitive histology was grade 1 chondrosarcoma, the surgical margins were wide. The evolution was favourable and the patient was able to perform all his activities of daily living independently without pain at 6 weeks postop. Knee flexion reached 90°. The oncologic screening at 18 months did not show local or distant recurrence. Conclusion: Joints near a benign tumour that suddenly become symptomatic or present an effusion might indicate a malignant transformation. Wide resection and prosthetic reconstruction remains an effective treatment option even in low grade cartilaginous lesions if (1) the adjacent joint is contaminated, or (2) joint-sparing surgery would result in a severe functional impairment of the limb.

Invasion of the laryngeal framework by thyroid carcinoma requires specific surgical techniques and carries a higher rate of complications that deserve to be highlighted. We reviewed our data from 1995 to 2012 and found six patients with laryngotracheal invasion by thyroid carcinoma. All underwent total thyroidectomy and single-stage cricotracheal resection, plus anterolateral neck dissection. Three had airway obstruction that necessitated prior endoscopic debulking. None of the patients needed a tracheotomy. There were four cases of papillary carcinoma, and two cases of undifferentiated carcinoma. One patient died of complications of the procedure (anastomotic dehiscence and tracheo-innominate artery fistula). Another died 2 months after the procedure from local recurrence and aspiration pneumonia. One case presented recurrence at 15 months, which was managed by re-excision and adjuvant radiotherapy; after 26 months of follow-up, he has no evidence of locoregional recurrence. The three other patients are alive without evidence of disease at 6, 18 and 41 months, respectively. Cricotracheal resection for subglottic invasion by thyroid carcinoma is an effective procedure, but carries significant risks of complications. This could be attributed to the devascularisation of the tracheal wall due to the simultaneous neck dissection, sacrifice of the strap muscles or of a patch of oesophageal muscle layer. We advocate a sternocleidomastoid flap to cover the anastomosis. Cricotracheal resection for subglottic invasion can be curative with good functional outcomes, even for the advanced stages of thyroid cancer. Endoscopic debulking of the airway prior to the procedure avoids tracheotomy.
