OBJECTIVE: Does surgery for deep infiltrating endometriosis (DIE) before in vitro fertilization (IVF) improve pregnancy and birth rate? PATIENTS AND METHODS: Cohort study of 177 consecutive patients with DIE related infertility and receiving IVF. Patients were divided into 3 groups according to surgical management decided during multidisciplinary team meeting. Group no surgery (NS) (n=65), group complete surgery (CS) with complete resection of all lesions (n=49) and group incomplete surgery (IS) with gestures improving ovaries accessibility for IVF and/or facilitating embryonic implantation (n=63). Pre-surgery clinical, MRI lesion locations, and history of IVF characteristics were analyzed with logistic regression. RESULTS: There was no significant difference in general and IVF characteristics and in the severity of endometriosis among the three groups (P=0.43). Overall pregnancy and birth rates after IVF were 45.8% and 33.3%, respectively and were not different among the 3 groups (P=0.59 and P=0.49). Four major complications during oocytes retrievals were observed in NS group, one in IS group and none in CS group. Presence of an inter-utero-rectal lesion at MRI decreased the rate of pregnancy (OR=0.49 [0.25, 0.97]). DISCUSSION AND CONCLUSIONS: Surgery for deep infiltrating endometriosis does not improve pregnancy and birth rates before IVF. This inter-utero-rectal extensive lesion might explain IVF failures by ovarian difficult access and difficulties in embryonic transfers. Further studies should explore the impact of surgical excision of inter-utero-rectal lesion on oocyte retrieval and embryonic transfer.

Surg. Oncol..  2015 ;22 :2714-2721

BACKGROUND: Studies focusing on the impact of obesity on survival in endometrial cancer (EC) have reported controversial results and few data exist on the impact of obesity on recurrence rate and recurrence-free survival (RFS). The aim of this study was to assess the impact of obesity on surgical staging and RFS in EC according to the European Society of Medical Oncology (ESMO) risk groups. METHODS: Data of 729 women with EC who received primary surgical treatment between January 2000 and December 2012 were abstracted from a multicenter database. RFS distributions according to body mass index (BMI) in each ESMO risk group were estimated using the Kaplan-Meier method. Survival was evaluated using the log-rank test, and the Cox proportional hazards model was used to determine influence of multiple variables. RESULTS: Distribution of the 729 women with EC according to BMI was BMI < 30 (n = 442; 60.6 %), 30 /= 35 (n = 141; 19.4 %). Nodal staging was less likely to be performed in women with a BMI >/= 35 (72 %) than for those with a BMI < 30 (90 %) (p < 0.0001). With a median follow-up of 27 months (interquartile range 13-52), the 3-year RFS was 84.5 %. BMI had no impact on RFS in obese women in the low-/intermediate-risk groups, but a BMI >/= 35 was independently correlated to a poorer RFS (hazard ratio 12.5; 95 % confidence interval 3.1-51.3) for women in the high-risk group. CONCLUSION: Severe obesity negatively impacts RFS in women with high-risk EC, underlining the importance of complete surgical staging and adapted adjuvant therapies in this subgroup of women.

BACKGROUND: Pancreatic islet transplantation offers a promising biotherapy for the treatment of type 1 diabetes, but this procedure has met significant challenges over the years. One such challenge is to address why primary graft function still remains inconsistent after islet transplantation. Several variables have been shown to affect graft function, but the impact of procedure-related complications on primary and long-term graft functions has not yet been explored. METHODS: Twenty-six patients with established type 1 diabetes were included in this study. Each patient had two to three intraportal islet infusions to obtain 10,000 islet equivalent (IEQ)/kg in body weight, equaling a total of 68 islet infusions. Islet transplantation consisted of three sequential fresh islet infusions within 3 months. Islet infusions were performed surgically or under ultrasound guidance, depending on patient morphology, availability of the radiology suite, and patient medical history. Prospective assessment of adverse events was recorded and graded using "Common Terminology Criteria for adverse events in Trials of Adult Pancreatic Islet Transplantation." RESULTS: There were no deaths or patients dropouts. Early complications occurred in nine of 68 procedures. beta score 1 month after the last graft and optimal graft function (beta score >/=7) rate were significantly lower in cases of procedure-related complications (P = 0.02, P = 0.03). Procedure-related complications negatively impacted graft function (P = 0.009) and was an independent predictive factor of long-term graft survival (P = 0.033) in multivariate analysis. CONCLUSION: Complications occurring during radiologic or surgical intraportal islet transplantation significantly impair primary graft function and graft survival regardless of their severity.

H., Zappa M.   Metastatic Prostate Cancer Incidence and Prostate-specific Antigen Testing: New Insights from the European Randomized Study of Screening for Prostate Cancer.  Eur. Urol..  2015 ;68 :885-890

BACKGROUND: The European Randomized Study of Screening for Prostate Cancer (ERSPC) has shown a 21% reduction in prostate cancer (PCa) mortality and a 1.6-fold increase in PCa incidence with prostate-specific antigen (PSA)-based screening (at 13 yr of follow-up). We evaluated PCa incidence by risk category at diagnosis across the study arms to assess the potential impact on PCa mortality. DESIGN, SETTING, AND PARTICIPANTS: Information on arm, centre, T and M stage, Gleason score, serum PSA at diagnosis, age at randomisation, follow-up time, and vital status were extracted from the ERSPC database. Four risk categories at diagnosis were defined: 1, low; 2, intermediate; 3, high; 4, metastatic disease. PSA (100 ng/ml) was used as the indicator of metastasis. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Incidence rate ratios (IRRs) for screening versus control arm by risk category at diagnosis and follow-up time were calculated using Poisson regression analysis for seven centres. Follow-up was truncated at 13 yr. Missing data were imputed using chained equations. The analyses were carried out on an intention-to-treat basis. RESULTS AND LIMITATIONS: In the screening arm, 7408 PCa cases were diagnosed and 6107 in the control arm. The proportion of missing stage, Gleason score, or PSA value was comparable in the two arms (8% vs 10%), but differed among centres. The IRRs were elevated in the screening arm for the low-risk (IRR: 2.14; 95% CI, 2.03-2.25) and intermediate-risk (IRR: 1.24; 95% CI, 1.16-1.34) categories at diagnosis, equal to unity for the high-risk category at diagnosis (IRR: 1.00; 95% CI, 0.89-1.13), and reduced for metastatic disease at diagnosis (IRR: 0.60; 95% CI, 0.52-0.70). The IRR of metastatic disease had temporal pattern similar to mortality, shifted forwards an average of almost 3 yr, although the mortality reduction was smaller. CONCLUSIONS: The results confirm a reduction in metastatic disease at diagnosis in the screening arm, preceding mortality reduction by almost 3 yr. PATIENT SUMMARY: The findings of this study indicate that the decrease in metastatic disease at diagnosis is the major determinant of the prostate cancer mortality reduction in the European Randomized study of Screening for Prostate Cancer.

INTRODUCTION: Myelolipomas and extramedullary hematopoietic tumors are uncommon benign tumors. They are variably composed of mature adipose tissue and hematopoietic tissue. Myelolipoma is usually observed in the adrenal gland and extramedullary hematopoietic tumors in the liver and spleen but may occasionally be found within solid tumors. CASE REPORT: A 62-year-old man without previous haematological history presented with a voluminous solitary bilateral renal tumor. Contrast-enhanced ultrasound CT-scan and scintigraphy with technetium-99m-nanocolloid and indium-111-chloride bone marrow were highly suggestive of extramedullary hematopoietic tumor. CT-guided biopsy suggested a diagnosis of myelolipoma. An atypical hereditary spherocytosis, undiagnosed until now, was demonstrated. CONCLUSION: We report, for the first time to our knowledge, a border form between extramedullary hematopoiesis tumor and myelolipoma of renal localisation revealing a hereditary spherocytosis in an adult patient.

OBJECTIVE: The aim of this study is to provide an automatic framework for computer-aided analysis of multiparametric magnetic resonance (mp-MR) images of prostate. METHOD: We introduce a novel method for the unsupervised analysis of the images. An evidential C-means classifier was adapted for use with a segmentation scheme to address multisource data and to manage conflicts and redundancy. RESULTS: Experiments were conducted using data from 15 patients. The evaluation protocol consisted in evaluating the method abilities to classify prostate tissues, showing the same behaviour on the mp-MR images, into homogeneous classes. As the actual diagnosis was available, thanks to the correlation with histopathological findings, the assessment focused on the ability to segment cancer foci. The method exhibited global sensitivity and specificity of 70 and 88 %, respectively. CONCLUSION: The preliminary results obtained by these initial experiments showed that the method can be applied in clinical routine practice to help making decision especially for practitioners with limited experience in prostate MRI analysis.

Surg. Oncol..  2015 ;22 :S964-S970

BACKGROUND: The goal, methods, and results of surgery for growing teratoma syndrome (GTS) in men after testicular cancer have been well described. The main surgical challenge relates to the need for vascular or thoracic procedures. But little is known about GTS in women, particularly regarding the optimal management of intraabdominal disease. This study aimed to evaluate the surgical management and outcomes (recurrences and fertility) for a large series of ovarian GTS. METHODS: This study retrospectively analyzed patients treated for an ovarian immature teratoma (IT) who subsequently experienced abdominal GTS requiring surgery. RESULTS: Between 1983 and 2014, 196 cases of IT were referred to the authors' institution or treated there, and 38 patients (19 %) subsequently experienced a GTS, including 10 cases of gliomatosis peritonei (containing exclusively pure mature glial tissue). The median age at diagnosis was 26 years (range 8-41 years), and the mean delay between IT and GTS diagnosis was 7 months (range 3-84 months). Surgical resection included peritonectomy (n = 22), diaphragmatic peritoneal resection (n = 14), bowel resection (n = 8), and splenectomy (n = 5). Conservative surgery was possible for 20 patients. Complete cytoreductive surgery was achieved for 25 patients. The mean follow-up period was 73 months (range 3-263 months). At least one recurrence developed for 10 patients (in the form of mature disease in all, and 8 of these patients had an initial complete resection. Five patients had a pregnancy. One patient died of complications from the disease (pulmonary embolism in a patient with bowel obstruction). CONCLUSIONS: The overall prognosis of abdominal GTS is good. The surgical procedures for GTS are similar to those used in debulking surgery for epithelial cancer. Whenever technically possible, a conservative surgery should be performed because spontaneous fertility is possible. Recurrent GTS is frequent even after complete surgery.
