RESUMEN
OBJECTIVE: Hot flashes are one of the major symptoms of climacteric syndrome. Despite the high prevalence of these symptoms, few questionnaires assessing the impact of hot flashes on quality of life have been validated. The aim of this study was to validate a French version of the Hot Flash Related Daily Interference Scale (HFRDIS) in a sample of French women. METHODS: In this prospective study, data were obtained from two groups of women aged between 40 and 60 years from both women without breast cancer and women under hormone therapy for breast cancer between March 2021 and February 2022. Translation was made by an official English-French translator using the forward-backward method. RESULTS: One hundred and sixty-seven women completed the HFRDIS questionnaire. The scree plots confirmed unidimensional structure. Cronbach's α coefficient was 0.92 [0.90-0.94] similar to the original version. The intra-class correlation coefficients of each item ranged between 0.58 and 0.71 Concordance of the scores of each item with those obtained during the validation of the original version of the HFRDIS was confirmed. CONCLUSION: The validation results show that the French version of the HFRDIS questionnaire is a valid tool to evaluate the impact of hot flashes on the daily life activities of patients.

INTRODUCTION: Since 2010, the network of rare malignant tumors of the ovary (TMRG) was developed to optimize the management of patients, also allowing a histological second opinion of rare ovarian tumors. The aim of this work was to study the contribution of second opinion to improve histological diagnostic accuracy on ovarian rare malignant tumors included in the TMRG database. MATERIAL AND METHODS: Histological data of patients diagnosed with a rare ovarian tumor included in TMRG network over a one-year period (2018) were collected. Initial diagnoses were compared with second opinion from national gynecological pathologist experts. The modalities of histological second opinion requests were studied, as well as the histological characteristics of the tumors. The discordances were classified as minor (if the modification of histological diagnosis did not change patient management) and major (if the patient management can be modified). RESULTS: Of 1185 included patients, 937 matched the inclusion criteria. Full concordance between primary diagnosis and expert second opinion was reached in 611 cases (65,3%), minor discordance was seen in 114 (12,2%) and major discordance in 209 (22,3%) of cases. In systematic review requested by the network, 26% (n = 137) of cases were reported with a change in histological diagnosis, while the change concerned 44% (n = 186) of cases for a second opinion spontaneously requested by the initial pathologist. The discrepancies concerned all categories of ovarian tumors, with a majority of mucinous tumors (43% of major discordances), followed by stromal and sex-cord tumors (13.8% of major discordances) and clear cell tumors (12,4% of major discordances). CONCLUSION: This analysis confirms the diagnostic difficulty of ovarian tumors, due to their rarity and morphological heterogeneity. French pathologists are aware of these difficulties and spontaneously refer ovarian tumors with unusual histology for a second opinion and collaborate with rare tumor networks for systematic review.

AIM OF THE STUDY: The main goal is to determine if the delay before going back to work after implant-based breast augmentation surgery is influenced by the healthcare coverage criteria. MEANS AND METHODS: In this retrospective, single center based study, patients who underwent implant-based breast augmentation surgery (excluding reconstructive surgery) in the past 3 years with a minimum follow-up of 1 month were questioned by telephone. Patients who had early postoperative complications, or no professional activity, were excluded. The demographic and perioperative data were collected and two groups were compared: those who were covered by the healthcare system and those who were not. RESULTS: Sixty patients were included. The two groups were comparable concerning the demographic (age, BMI, children, work intensity, smoking status, comorbidity) and surgical data (surgical approach, type, volume and position of the implant, operative time and drainage). There was a significant difference between the groups concerning the delay of return to work (P=0.0001): 18.4 days for reimbursed patients versus 9.45 days for patients without healthcare coverage. CONCLUSION: For the same implant-based breast augmentation surgery, and for the same population, the duration of postoperative recovery period doubles for the patients for whom surgery is reimbursed by the healthcare system.

BACKGROUND: Our objective was to concomitantly assess distribution of lymphatic and nerve structures in the parametrium. METHODS: Twenty hemipelvises from ten fresh cadavers were dissected to differentiate between, three different parts of the parametrium: the lateral parametrium, the proximal and the distal part of the posterior parametrium. Histologic and immunofluorescence analyses of nerve and lymphatic structures were performed using NSE and LYVE-1 staining, respectively. The percentage of structures was independently scored as 0 (0%), 1 (1-20%), 2 (20-50%), 3 (50-80%), 4 (>80%). RESULTS: The lateral parametrium and the proximal part of the posterior parametrium contained both nerve (scored 2.25 and 2.50, respectively) and lymphatic (scored 2.50 and 2.00, respectively) structures. The distal part of the posterior parametrium also contained numerous nerve structures (scored 2.00) but lymphatic structures were rare (scored 0.88). No difference in nerve distribution was found according to the parts of parametrium while a significantly lower distribution of lymphatic vessels was observed in the distal part of the posterior parametrium (p=0.03). CONCLUSION: The distal part of the posterior parametrium is of high nerve density and low lymphatic density raising the issue as to whether it should be removed during radical hysterectomy.

Although many series have been published on the management of digestive or urinary deep infiltrating endometriosis (DIE), few data exist on pre- and postoperative urinary dysfunction (UD) and urodynamic tests. Hence, the objective of this review was to evaluate the pre- and postoperative incidence of UD and the contribution of urodynamic tests as well as their therapeutic implications. Studies published between January 1995 and April 2012, available in the databases Medline, Embase or the Cochrane Library and responding to a key word algorithm were selected. Studies were classified according to their level of evidence in the Canadian Task Force classification. Sixty-three studies were included in this review. The incidence of preoperative UD is unknown in patients with DIE without colorectal involvement but ranges from 2% to 48% in patients with colorectal endometriosis. About half of all the patients had abnormal urodynamic test results. DIE surgery is associated with a risk of urinary dysfunction mainly corresponding to de novo voiding dysfunction in 1.4% to 29.2% of cases with a mean value of 4.8%. The rate of persistent voiding dysfunction ranges from 0 to 14.7% with a mean value of 4.6%. Risk factors of postoperative UD are the need for partial colpectomy, parametrectomy and patients requiring colo-anal anastomosis. For patients with urinary tract endometriosis, the incidence of preoperative UD is comprised between 24.4% and 79.2% with a rate of postoperative voiding dysfunction ranging from 0% to 16.9% with a mean value of 11.1%. Prevention of postoperative UD is based on nerve-sparing surgery. Treatment of voiding dysfunction requires self-catheterization. There is a lack of data on medical treatment and surgical techniques to manage postoperative UD. More effort needs to be made to detect preoperative UD associated with DIE. Preoperative evaluation by urodynamic tests and possibly electrophysiology could be of interest especially in patients with risk factors. The current review underlines the difficulties of establishing clear recommendations due to heterogeneity of the studies and the absence of a consensual definition of UD.

BACKGROUND: Chemoradiotherapy (CRT) is the standard of care for patients diagnosed with locally advanced cervical cancer (LACC), a human papillomavirus (HPV)-related cancer that relapses in 30%-60% of patients. This study aimed to (i) design HPV droplet digital PCR (ddPCR) assays for blood detection (including rare genotypes) and (ii) monitor blood HPV circulating tumor DNA (HPV ctDNA) levels during CRT in patients with LACC. METHODS: We analyzed blood and tumor samples from 55 patients with HPV-positive LACC treated by CRT in a retrospective cohort (n = 41) and a prospective cohort (n = 14). HPV-ctDNA detection was carried out by genotype-specific ddPCR. RESULTS: HPV ctDNA was successfully detected in 69% of patients (n = 38/55) before CRT for LACC, including nine patients with a rare genotype. HPV-ctDNA level was correlated with HPV copy number in the tumor (r = 0.41, P < 0.001). HPV-ctDNA positivity for HPV18 (20%, n = 2/10) was significantly lower than for HPV16 (77%, n = 27/35) or other types (90%, n = 9/10, P = 0.002). HPV-ctDNA detection (positive versus negative) before CRT was associated with tumor stage (P = 0.037) and lymph node status (P = 0.02). Taking into account all samples from the end of CRT and during follow-up in the prospective cohort, positive HPV-ctDNA detection was associated with lower disease-free survival (DFS) (P = 0.048) and overall survival (OS) (P = 0.0013). CONCLUSION: This is one of the largest studies to report HPV-ctDNA detection before CRT and showed clearance of HPV ctDNA at the end of treatment in most patients. Residual HPV ctDNA at the end of CRT or during follow-up could help to identify patients more likely to experience subsequent relapse.

Primary angiosarcoma is a rare type of breast cancer, the diagnosis is difficult to establish and it has the worst prognostic of all breast malignancies. Two cases of primary breast angiosarcoma have been observed at the centre Henry Kaplan of Tours and at the hospital La Source of Orleans since 2001. Based on a literature review, we analyse the epidemiological, pathological, clinical, diagnostic and treatment aspect of this type of cancer. Mastectomy is the reference treatment and the benefit of radiotherapy and chemotherapy remains to be demonstrated.

Splenosis is the autotransplantation of splenic tissue, generally after traumatic splenic rupture. Usually, the peritoneal surface is affected. The viscera are rarely involved in this graft. We report a case of intrahepatic splenosis, which presented as a liver tumour on imagery in a 55-year-old man followed for lung carcinoma and chronic hepatitis C and who had undergone a splenectomy for trauma 22 years before. The different characteristics and diagnostic methods of 16 cases of hepatic splenosis are presented from the literature. These different reports emphasize the necessity of considering splenosis in the differential diagnosis of hepatic tumours.

The purpose of this study is to assess the value of US guided vacuum-assisted breast biopsy compared to surgery for management of intraductal papilloma. This retrospective study included 13 patients with hypoechoic nodular lesion corresponding to small benign intraductal papillomas on biopsy and visible by US. The lesions were removed using US-guided vacuum-assisted biopsy and all tissue material was reviewed at histology. The mean size of papillomas was 9.3 mm (5-16 mm). Vacuum-assisted tumor removal was considered total for all 13 lesions. Maximum follow-up was 57 months. Two patients had tumor recurrence at 22 and 28 months respectively. In one case, atypical ductal hyperplasia was present at the periphery of the papilloma, requiring complementary surgery. US-guided vacuum-assisted excision of small benign tumors such as solitary intraductal papillomas appears to be an alternative to surgical biopsy. Because of the large volume of tissue removed, total tumor excision is possible allowing detection of incidental associated lesions.

INTRODUCTION: To assess the mode of delivery and Caesarean Section (CS) rate after successful External Cephalic Version (ECV). MATERIAL AND METHODS: A matched case-control study. Data were gathered from a tertiary care university hospital register from 1996-2015. All pregnant women who delivered after successful External Cephalic Version (ECV). Among 643 women who attempted ECV, we identified 198 with successful ECVs and compared them with the next two women who presented for labor management with spontaneous cephalic presentation, matching for delivery date, maternal age, parity, body mass index, and delivery history using univariate and stepwise logistic regression. The main outcome measure was the risk of caesarean. RESULTS: The caesarean section rate was higher after successful ECV (respectively 20.7% versus 7.07%, P<0.05). Caesarean section for abnormal fetal head position (forehead, bregma, face) was higher after successful ECV (28.6% versus 0%). After adjustment for matching and confounding variables (variation of the caesarean section rate over the study period, gestational maternal complications, antepartum fetal complications, term of delivery, induction of labor, oxytocin use for dystocia, neonatal cephalic perimeter), a successful ECV increased the risk of caesarean section (adjusted OR 3.17, 95% CI 1.86-5.46). By stratifying on week, a trend for increased risk for caesarean section was observed at the week after ECV and at post term (28.6% before 37+6, 14.8% at 38+0-38+6, 13.8% at 39+0-39+6, 14.2% at 40+0-40+6 and 33.3% beyond 41+0 weeks' gestation, P=0.06). CONCLUSIONS: Women who have a successful ECV are at increased risk of caesarean section compared with women who experience spontaneous cephalic presentation.

Breast cancer involves various types of tumors. The objective of this review was to provide a summary of the main methods currently available in clinical practice to characterize breast cancers at a molecular level and to discuss their prognostic and predictive values. Hormonal receptors expression and the HER2 status are prognostic markers and can also predict the response to targeted therapies. Their analysis through immunohistochemistry is systematical. Ki67 is an effective prognostic marker, but its reliability is debated because of its low reproducibility between laboratories and between pathologists. Commercial genomic signatures are all considered valid prognostic tools and may guide physicians to make therapeutic choices. These signatures are costly and should therefore be restricted to situations in which the use of chemotherapy remains equivocal.

In this work, the in vitro effects of very-low-density lipoproteins (VLDL) on human polymorphonuclear leukocyte (PMN) oxidative metabolism and migration were studied. VLDL stimulated PMN superoxide generation in absence of other stimulating agents. The effect of VLDL from normotriglyceridemic subjects was more marked than with VLDL from hypertriglyceridemic subjects. VLDL reduced in a dose-dependent manner the luminol-dependent chemiluminescence of PMN stimulated by phorbol myristate acetate (PMA) and, to a lesser degree, by opsonized zymosan. This effect was observed with VLDL concentrations found in healthy and hypertriglyceridemic patients. Superoxide anion generation was also reduced by preincubation of PMN with VLDL before stimulation with PMA but not opsonized zymosan. VLDL were not cytotoxic for PMN. The above effects appear to be an intrinsic property of VLDL and might lead to reduced PMN-mediated non-specific host defences in hypertriglyceridemic subjects.

PURPOSE: To assess US-guided vacuum-assisted biopsies in the diagnosis of suspicious sonographic breast lesions after non-diagnostic core needle biopsies (CNB). PATIENTS AND METHODS: Retrospective study of 42 females with suspicious breast lesions at US. CNB previously performed were non-diagnostic. Because of the larger sample size, vacuum-assisted biopsies were performed, instead of surgical biopsy. RESULTS: Vacuum-assisted biopsies showed 32 benign lesions. Histologic examination of the CNB showed non-specific fibrous tissue in 43% of cases as opposed to 7.1% for vacuum-assisted biopsies. The latter provided a more specific diagnosis (mainly fibrocystic breast disease). From a total of 4 lesions that were suspicious at CNB, 3 were diagnosed as malignancies after vacuum-assisted biopsy and one case was a "borderline" lesion. Three additional malignant and three additional borderline lesions were diagnosed on vacuum-assisted biopsies. In 11 cases, surgical excision was performed, and all diagnoses from vacuum-assisted biopsies were confirmed at microscopy, except in one case where it was underestimated (ADH versus DCIS). CONCLUSION: US-guided vacuum-assisted biopsy is a reliable technique. Because it provides more tissue than CNB, it can be an alternative to diagnostic surgery after non-diagnostic CNB. Indeed, it allows confirmation of the diagnosis and provides a more specific diagnosis of benign lesions. With regards to malignant and borderline lesions, it avoids the risk of false-negative CNB and overlooking carcinomas.

AIM: The objective of this study was to determine the effects of axillary lymph node dissection (ALND) versus sentinel lymph node biopsy alone (SLNB) on the survival of patients with 3 or more metastatic lymph nodes (MLN) in invasive breast cancer. METHODS: Data of 9521 patients with invasive T1-2M0 breast carcinoma and initial treatment with SLNB completed or not by ALND and 3 or more MLN were extracted from the SEER database. Univariate and multivariate analyses were performed. RESULTS: Overall, 9521 patients were included in the study. SLNB-alone compared with ALND did not result in different overall survival (OS) or specific survival (SS) for patients with 3 or more MLN (p = 0.46 and 0.58, respectively). In subgroup analyses, OS was comparable between SLNB-alone and ALND when patients had only 3 or more than 3 MLN. When patients had 3 MLN, the 5-year SS was significantly better for patients with ALND compared with SLNB-alone: 91.5% and 85.1%, respectively (p = 0.02). The Hazard Ratio (HR) for OS comparing SLNB-alone with ALND adjusting for age, adjuvant radiotherapy, tumor size, estrogen receptor status, grade and tumor type resulted in an HR of 1.05 (95% CI, 0.72-1.54, p = 0.77). CONCLUSION: In conclusion, patients with a T1-T2 invasive breast cancer and at least 3 MLN do not benefit from ALND after SLNB for specific and overall survival, thus limiting ALND to a staging procedure. A subgroup of patients with 3 MLN had a better SS with ALND, possibly due to an under-staging of the SLNB-alone group.

AIMS: In patients with breast cancer, the association between the number of sentinel lymph node (SLN) removed and survival is poorly known. Our objective was to evaluate this association on disease-specific survival (DSS). METHODS: Data of 144 517 patients with invasive T1-3M0 breast carcinoma and initial treatment with SLN biopsy were extracted from the SEER database. Univariate and multivariate analyses were performed. RESULTS: The number of SLNs harvested and the completion of axillary lymph node dissection (ALND) were not associated with DSS improvement for patients without metastatic nodes. After adjustment, patients with three SLNs had a better DSS than did other groups (HR of 0.73 CI 95% [0.60-0.88], p = 0.001). This result was mainly driven by the group of patients with one metastatic LN. When patients had two or more metastatic LNs, there was no difference in DSS according to the number of SLNs or to completion of ALND. CONCLUSIONS: The number of SLN harvested was associated with DSS. According to DSS, the optimal number of SLNs harvested was three in this large series, thereby calling into question the understaging or undertreatment of SLN biopsy in which only one or two SLNs are harvested but also the therapeutic effect of completion ALND.

Polymorphonuclear leukocytes (PMN) generate highly reactive oxygen derived free radicals that may cause lipoprotein lipid oxidation and so contribute to the pathogenesis of atherosclerosis. On the other hand it has been shown that lipoproteins can alter cell functions in vitro. We therefore studied the effects of atherogenic lipoproteins, VLDL and LDL, on the production of superoxide anion by human PMN in the presence or absence of formyl-methionyl-leucyl-phenylalanine (fMLP). VLDL and LDL stimulate PMN superoxide production and potentialize PMN stimulation by fMLP. The lipid moiety of the lipoproteins might be mainly involved in these effects. The binding of radio-labelled fMLP to its specific membrane receptor was significantly enhanced in the presence of VLDL and only slightly in the presence of LDL. The study of the signal transduction suggests that modulation of phospholipase D and A2 activities could be involved in the modification by LDL of PMN response to fMLP.

Twelve of the urine parameters, namely sodium, potassium, chloride, urea, creatinine, uric acid, calcium, phosphate, protein, microalbumin, amylase and glucose, routinely measured in a biochemistry laboratory were chosen to revalue their interest in clinical practice. For each parameter, urinary collection method, physiologic review and specific indications were set out. The clinical interest of chloride, urea, phosphate or uric acid measurement seem limited to specific pathological conditions. The measurement of urine amylase is out of interest.

Post-vaccination granulomas a well-known reaction due to aluminium adsorbed vaccines. We report three cases of children who developed subcutaneous nodules at the site of a previous injection of Tetracoq*vaccine (tetanus, diphtheria, Bordetella pertussis, poliovirus). Histologically, the lesions were characterized by a necrotizing granulomatous reaction with eosinophilic crystalline material. This material stained positively with the solochrome cyanine stain and was pink-purple. This aluminium stain enabled diagnosis of post-immunization injection-site reaction due to aluminium.

PURPOSE: We attempted to find ultrasound scar subsequent to vacuum assisted breast biopsy (Mammotome system) previously performed, and to enhance its value for preoperative localization. MATERIALS AND METHODS: Our study included 34 females requiring needle localization prior to surgery. They previously had Mammotome core biopsies for clustered microcalcifications. US examination was systematically performed before insertion of the metallic marker, in order to detect a scar. Identification of the scar allowed ultrasonographic guided localization. The accuracy was correlated with histologic findings. RESULTS: Ultrasonography detected a scar in 21 of the 34 patients (63%). Among all these cases, a perfect correlation could be established between ultrasound target and histologic scar revealed by microscopic examination. CONCLUSION: Ultrasound detection of scar allows ultrasonographic guidance and can therefore be the only alternative in cases of absence or displacement of the marker clip.
