RESUMO

Objective: To investigate the relationship between self-reported osteoarthritis (OA) and reproductive factors in the Women's Health Initiative (WHI). Method: We used multivariable logistic regression to study the association of self-reported OA and reproductive factors in the WHI Observational Study and Clinical Trial cohorts of 145 965 postmenopausal women, in a retrospective cross-sectional format. Results: In our cohort, we observed no clinically significant associations between reproductive factors and OA given small effect sizes. The following factors were associated with statistically significant increased likelihood of developing OA: younger age at menarche (p < 0.001), history of hysterectomy [adjusted odds ratio (aOR) 1.013, 95% confidence interval (CI) 1.004-1.022, p = 0.04 vs no hysterectomy], history of unilateral oophorectomy (aOR 1.015, 95% CI 1.004-1.026, p < 0.01 vs no oophorectomy), parity (aOR 1.017, 95% CI 1.009-1.026, p < 0.001), ever use of oral contraceptives (aOR 1.008, 95% CI 1.001-1.016, p < 0.01 vs never use), and current use of hormonal therapy (reference current users, aOR 0.951, 95% CI 0.943-0.959 for never users; aOR 0.981, 95% CI 0.972-0.989 for past users; global p < 0.001). Age at menopause, first birth, and pregnancy were not associated with OA. Among parous women, no clear pattern was observed with number of pregnancies, births, or duration of breastfeeding in relation to OA. Conclusion: Our study showed that reproductive factors did not have significant clinical associations with OA after controlling for confounders. This may be due to complex hormonal effects. Additional investigation is warranted in prospective cohort studies. The Women's Health Initiative is registered under ClinicalTrials.gov. Trial registration ID: NCT00000611.

RESUMO

BACKGROUND: Low-grade serous ovarian carcinoma (LGSOC) is a rare disease that accounts for 5% of all ovarian cancers and requires surgical complete debulking. To date, the prognostic value of pelvic and paraaortic lymphadenectomy remains unclear in this population. PATIENTS AND METHODS: This retrospective cohort of patients with a diagnosis of LGSOC was registered in the Tumeurs Malignes Rares Gynécologiques national network, between January 2000 and July 2017, at 25 centers. All LGSOC were confirmed after pathological review and operated by primary debulking surgery (PDS) or interval debulking surgery after neoadjuvant chemotherapy (NACT-IDS). Primary endpoints were overall survival (OS) and progression-free survival (PFS). RESULTS: A total of 126 patients were included, 86.1% were stage III/IV, and 74.6% underwent lymph node dissection (LND). According to the Completeness of Cancer Resection (CCR) score, 83.7% had complete resection. Median OS was 130 months, and median PFS was 41 months. Pelvic and paraaortic LND had no significant impact on OS (p = 0.78) or DFS (p = 0.93), and this was confirmed in subgroups (advanced stages FIGO III/IV, CCR score 0/1 or 2/3, and timing of surgery PDS or NACT-IDS). Histological positive paraaortic lymph nodes had a significant negative impact on PFS in the whole population (HR 2.21, 1.18-4.39, p = 0.02) and in the CC0/CC1 population (HR, 2.28, 1.13-4.59, p = 0.02). CONCLUSIONS: Systematic pelvic and paraaortic LND in patients with LGSOC improved neither overall nor PFS. A prospective trial would be necessary to validate these results but would be difficult to conduct due to the rarity of this disease.

RESUMO

BACKGROUND: The outcomes of paraaortic lymphadenectomy were compared for the treatment of gynecological malignancies to identify the most appropriate surgical approach. METHODS: Our retrospective, multicentric study included 1304 patients who underwent paraaortic lymphadenectomy for gynecological malignancies. The patients were categorized into the following five groups based on treatment type: transperitoneal laparoscopy (group A, n = 198), extraperitoneal laparoscopy (group B, n = 681), robot-assisted transperitoneal laparoscopy (group C, n = 135), robot-assisted extraperitoneal laparoscopy (group D, n = 44), and laparotomy (group E, n = 246). RESULTS: The prevalence of cancer types differed according to the surgical approach: there were more ovarian cancers in group E and more cervical cancers in groups B and D (p < 0.001). Estimated blood loss was higher in group E (844.2 mL) than in groups treated with minimally invasive interventions (115.8-141.5 mL, p < 0.005). For infrarenal dissection, fewer nodes were removed in group C compared with the other approaches (16 vs. 21 nodes, respectively, p < 0.05). The average operative time ranged from 169 min for group A to 247 min for group E (p < 0.001). Length of hospital stay was 14 days for group E versus 3.5 days for minimally invasive procedures (p < 0.05). The early postoperative grade 3 and superior Dindo-Clavien complications occurred in 9-10% of the patients in groups B-D, 15% of the patients in group E, and only 3% and 4% for groups A and C, respectively. The most common complication was lymphocele. CONCLUSIONS: Laparotomy increases preoperative and postoperative morbidity. The robot-assisted transperitoneal approach demonstrated a poorer lymph node yield than laparotomy and extraperitoneal approaches.

RESUMO

OBJECTIVE: The French national rare gynecological tumor network has been established to improve the quality of care through offering expertise in double reading histological diagnosis, reviewing cases and guiding management of these tumors through specialized multidisciplinary tumor boards and online clinical guidelines (www.ovaire-rare.com). The aim of this study is to evaluate the impact of the development and implementation of this network by assessing the conformity of medical practice with the guidelines concerning the granulosa cell tumors (GCTs). METHODS: This is a French nationwide study, including 463 patients (out of the 639 identified patients) with a definitive diagnosis of GCT between 2011 and 2016. Surgical practices were analyzed for conformity with the current guidelines (www.ovaire-rare.org). Medical records, surgical and pathological reports were systematically analyzed. Total conformity was defined by a conservative (unilateral salpingo-oophorectomy) or radical surgery (hysterectomy and bilateral salpingo-oophorectomy) including surgical staging (omentectomy, peritoneal biopsies and peritoneal cytology) according to the FIGO stage. Partial conformity referred to a conservative or radical surgery without surgical staging and non-conformity was defined as a non-optimal surgery as recommended by the guidelines. RESULTS: Median age at diagnosis was 49 years old (range 10-89). The median size of tumor was 94 mm (range 5-400). Radical surgery was performed in 240 patients (52%); while a fertility-sparing surgery was performed in 98 cases (21%). A surgical staging was performed in 76 cases (16%) and an evaluation of the endometrium in 289 cases (62%). Surgery was fully compliant with the guidelines in 65 patients (14%), partially compliant in 213 patients (46%), non-compliant in 137 patients (30%) and not assessable in 48 cases (10%). A statistically significant difference for compliance was observed in restaging surgery (p < 0,001), radical surgery (p = 0,017) and the period (before or after) of the implementation of the network (p < 0,001). Survival analyses did not allow us to demonstrate a significant difference in overall survival nor in PFS although there was a trend in favor of optimal surgery compared to incomplete/non optimal surgery. CONCLUSION: Surgical management's conformity to the guidelines increases over time from 2011 to 2016. According to this study, the implementation of a national network dedicated to rare gynecologic tumors seems to significantly improve the surgical management of the patients with ovarian granulosa cell tumors.

RESUMO

Immediate vaginal reconstruction is usually offered following pelvic exenteration for recurrent cervical cancer in women previously treated with radiotherapy or with severe radiation-induced fistulae. Introduction of muscle-sparing flaps, such as the pedicled vertical deep inferior epigastric perforator (DIEP) flap, provides viable tissues for vaginal reconstruction and is associated with reduced donor-site morbidity. This report describes the surgical technique, which is one of the procedures of choice for vaginal reconstruction. It is safe and beneficial, especially for women with gynecologic cancer who have undergone pelvic exenteration after failed radiation therapy.

RESUMO

Methodological limitations preclude determination of the association between sleep duration and bone mineral density (BMD) from existing literature. This was the first study to use objective sleep duration to determine its association with BMD. Nocturnal sleep duration, assessed objectively (actigraphy) or subjectively (questionnaire), was not independently associated with BMD in postmenopausal women. INTRODUCTION: Both long and short self-reported sleep durations are associated with low bone mineral density (BMD) in men and women. The association between sleep duration measured by actigraphy and BMD in postmenopausal women is unknown. METHODS: The Study of Osteoporotic Fractures (SOF) ancillary sleep study was used to determine the association between sleep duration and BMD at the total hip and femoral neck in postmenopausal women ≥ 75 years old. Sleep duration was assessed by wrist actigraphy (average 4 nights) and questionnaire. BMD was compared between postmenopausal women with short (< 6 h/night) vs. NIH-recommended (7-8 h/night) sleep durations. Data were analyzed using a 2-sample t test (unadjusted) and multivariate regression model (adjusted). Simple linear regression was used to estimate the difference in BMD per additional hour of sleep when sleep duration was considered as a continuous, rather than dichotomized, variable. RESULTS: Total hip BMD was higher in women with actigraphically assessed shorter sleep duration in unadjusted models only. No clinically or statistically significant differences in total hip or femoral neck BMD were observed according to nocturnal sleep duration after adjusting for body mass index (BMI) in dichotomized (N = 874) or continuous (N = 1624) sleep duration models or when subjective sleep duration was used. When sleep duration included daytime naps, longer sleep duration was associated with lower total hip BMD (ß = - 0.005, p = 0.04). CONCLUSIONS: Nocturnal sleep duration, whether assessed objectively (actigraphy) or subjectively (questionnaire), was not independently associated with BMD in older postmenopausal women.

RESUMO

The paper focuses on the identification of atypical fractures (AFFs). This paper examines the concordance between objective classification and expert subjective review. We believe the paper adds critical information about how to apply the American Society of Bone and Mineral Research (ASBMR) criteria to diagnose AFFs and is of high interest to the field. INTRODUCTION: Assess American Society of Bone and Mineral Research (ASBMR) criteria for identifying atypical femoral fractures (AFFs). METHODS: Two orthopedic surgeons independently evaluated radiographs of 372 fractures, applying ASBMR criteria. We assessed ease of applying ASBMR criteria and whether criteria-based assessment matched qualitative expert assessment. RESULTS: There was up to 27% uncertainty about how to classify specific features. 84% of films were classified similarly for the presence of AFF according to ASBMR criteria; agreement increased to 94% after consensus meeting. Of 37 fractures categorized as AFFs based on ASBMR criteria, 23 (62.2%) were considered AFFs according to expert assessment (not relying on criteria). Only one (0.5%) femoral shaft fracture that did not meet ASBMR criteria was considered an AFF per expert assessment. The number of major ASBMR features present (four vs five) and whether there was periosteal or endosteal thickening ("beaking" or "flaring") played major roles in the discrepancies between ASBMR criteria-based and expert-based determinations. CONCLUSIONS: ASBMR AFF criteria were useful for reviewers but several features were difficult to interpret. Expert assessments did not agree with the ASBMR classification in almost one-third of cases, but rarely identified an AFF when a femoral shaft fracture did not meet ASBMR AFF criteria. Experts identified lateral cortical transverse fracture line and associated new-bone formation along with no or minimal comminution as crucial features necessary for the definition of atypical femoral fractures.

RESUMO

AIMS: To examine (1) the prevalence of depressive symptoms in women with Type 2 diabetes, (2) the associations between depressive symptoms and the following dependent variables: sleep disturbance; physical activity; physical health-related; and global quality of life, and (3) the potential moderating effects of antidepressants and optimism on the relationship between depressive symptoms and dependent variables. METHODS: Participants in the Women's Health Initiative who had Type 2 diabetes and data on depressive symptoms (N=8895) were included in the analyses. In multivariable linear regression models controlling for sociodemographic, medical and psychosocial covariates, we examined the main effect of depressive symptoms, as well as the interactions between depressive symptoms and antidepressant use, and between depressive symptoms and optimism, on sleep disturbance, physical activity, physical health-related quality of life; and global quality of life. RESULTS: In all, 16% of women with Type 2 diabetes reported elevated depressive symptoms. In multivariable analyses, women with depressive symptoms had greater sleep disturbance (P<0.0001) and lower global quality of life (P<.0001). We found evidence of significant statistical interaction in the models for quality-of-life outcomes: the increased risk of poor physical health-related quality of life associated with antidepressant use was stronger in women without vs with depressive symptoms, and the association between greater optimism and higher global quality of life was stronger in women with vs without depressive symptoms. CONCLUSIONS: To improve health behaviours and quality of life in women with Type 2 diabetes, sociodemographic and medical characteristics may identify at-risk populations, while psychosocial factors including depression and optimism may be important targets for non-pharmacological intervention.

RESUMO

BACKGROUND: Pelvic exenteration remains one of the most mutilating procedures, with important postoperative morbidity, an altered body image, and long-term physical and psychosocial concerns. This study aimed to assess quality of life (QOL) during the first year after pelvic exenteration for gynecologic malignancy performed with curative intent. METHODS: A French multicentric prospective study was performed by including patients who underwent pelvic exenteration. Quality of life by measurement of functional and symptom scales was assessed using the European Organisation for Research and Treatment of Cancer (EORTC) QLQ-C30 (version 3.0) and the EORTC QLQ-OV28 questionnaires before surgery, at baseline, and 1, 3, 6, and 12 months after the procedure. RESULTS: The study enrolled 97 patients. Quality of life including physical, personal, fatigue, and anorexia reported in the QLQ-C30 was significantly reduced 1 month postoperatively and improved at least to baseline level 1 year after the procedure. Body image also was significantly reduced 1 month postoperatively. Global health, emotional, dyspnea, and anorexia items were significantly improved 1 year after surgery compared with baseline values. Unlike younger patients, elderly patients did not regain physical and social activities after pelvic exenteration. CONCLUSIONS: Therapeutic decision on performing a pelvic exenteration can have a severe and permanent impact on all aspects of patients' QOL. Deterioration of QOL was most significant during the first 3 months after surgery. Elderly patients were the only group of patients with permanent decreased physical and social function. Preoperative evaluation and postoperative follow-up evaluation should include health-related QOL instruments, counseling by a multidisciplinary team to cover all aspects concerning stoma care, sexual function, and long-term concerns after surgery.

RESUMO

BACKGROUND: Rare ovarian tumors represent >20% of all ovarian cancers. Given the rarity of these tumors, natural history, prognostic factors are not clearly identified. The extreme variability of patients (age, histological subtypes, stage) induces multiple and complex therapeutic strategies. METHODS: Since 2011, a national network with a dedicated system for referral, up to 22 regional and three national reference centers (RC) has been supported by the French National Cancer Institute (INCa). The network aims to prospectively monitor the management of rare ovarian tumors and provide an equal access to medical expertise and innovative treatments to all French patients through a dedicated website, www.ovaire-rare.org. RESULTS: Over a 5-year activity, 4612 patients have been included. Patients' inclusions increased from 553 in 2011 to 1202 in 2015. Expert pathology review and patients' files discussion in dedicated multidisciplinary tumor boards increased from 166 cases in 2011 (25%) to 538 (45%) in 2015. Pathology review consistently modified the medical strategy in 5-9% every year. The rate of patients' files discussed in RC similarly increased from 294 (53%) to 789 (66%). An increasing number (357 in 5 years) of gynecologic (non-ovarian) rare tumors were also registered by physicians seeking for pathological or medical advice from expert tumor boards. CONCLUSION: Such a nation-wide organization for rare gynecological tumors has invaluable benefits, not only for patients, but also for epidemiological, clinical and biological research.

RESUMO

INTRODUCTION: The direct relationship between surgical radicality to compensate biologic behavior and improvement of patient outcome at the time of primary or interval cytoreduction remains unclear. OBJECTIVE: The aim of this study was to evaluate the impact of disease extension and surgical complexity on survival after complete macroscopic resection for stage IIIC-IV ovarian cancer. MATERIALS AND METHODS: Medical records from seven referral centers in France were reviewed to identify all patients who had complete cytoreductive surgery for stage IIIC-IV epithelial ovarian, fallopian, or primary peritoneal cancer. All patients had at least six cycles of carboplatin and paclitaxel combination therapy. RESULTS: From the 374 consecutive patients with complete cytoreduction who were included in this study, stage, grade, upper abdominal disease, surgical complexity, and carcinomatosis extent were significantly associated with disease-free survival (DFS) at univariate analysis. Stage IV and the need for ultra-radical procedures were significantly associated with lower overall survival (OS). On multivariate analysis, radical surgery, including more than two visceral resections, was significantly associated with decreased DFS and OS. CONCLUSIONS: Patients who need complex surgical procedures involving two or more visceral resections in order to achieve successful complete cytoreduction have worse outcome than patients with less extensive procedures. The negative impact of surgical complexity was not significant in patients who underwent upfront procedures. Tumor volume and extension were associated with decreased DFS in patients undergoing a primary surgical approach. This adds to the evidence that, even though complete cytoreduction is currently the objective of surgery, tumor load remains an independent poor prognostic factor and probably reflects a more aggressive behavior.

RESUMO

BACKGROUND: This study was designed to evaluate detection rate and anatomical location of sentinel lymph node (SLN) at lymphoscintigraphy, to compare short and long lymphoscintigraphy protocols, and to correlate lymphoscintigraphic and surgical mapping of SLN in patients with early-stage endometrial cancer (EC). METHODS: Subanalysis of the prospective multicenter study Senti-endo performed from July 2007 to August 2009. Patients with stage I and II EC received four cervical injections of 0-2 mL of unfiltered technetium sulphur colloid the day before (long protocol) or the morning (short protocol) before surgery. SLN detection used a combined technetium/patent blue labeling technique, and all patients had a systematic bilateral pelvic lymphadenectomy. RESULTS: A total of 133 patients were enrolled in the study and 118 (94.5 %) underwent a lymphoscintigraphy. Of these 118 patients, 44 (37 %) underwent a short protocol and 66 (56 %) a long protocol (data on lymphoscintigraphy were not available in eight patients). Lymphoscintigraphic detection rate was 74.6 % (34 % for short protocol and 60.2 % for long protocol). No difference in the detection rate was observed according to lymphoscintigraphy protocol (p = 0.22), but a higher number of SLN was noted for the long protocol (p = 0.02). Aberrant drainage was noted on lymphoscintigraphy in 30.5 % of the patients. Paraaortic SLNs were exclusively detected using the long protocol. A poor correlation was noted between short (κ test = 0.24) or long lymphoscintigraphy (κ test = 0.3) protocol and SLN surgical mapping. CONCLUSIONS: Our study demonstrates that preoperative lymphoscintigraphy allowed a high SLN detection rate and that long lymphoscintigraphy protocol was associated with a higher detection of aberrant drainage especially in the paraaortic area.

RESUMO

SUMMARY: Bisphosphonate therapy reduces fracture risk but does not eliminate fracture occurrence. We determined the fracture incidence and risk factors for fractures among 14,674 bisphosphonate users in a community setting. Bisphosphonate users remained at risk of fracture, and additional measures to prevent fractures in these patients would be beneficial. INTRODUCTION: Bisphosphonate therapy reduces but does not eliminate fracture occurrence. The incidence of fracture and risk factors for fractures among persistent, current users of bisphosphonates in a community setting have not been well studied. METHODS: We conducted a retrospective cohort study of 14,674 bisphosphonate users in a health maintenance organization. Patients were followed until a 3-month gap in therapy, creating a pool of highly compliant [mean medication possession ratio (MPR) of 94%] current users. We used Cox proportional hazards models to identify risk factors for fractures among these persistent, current users. RESULTS: There were 867 fractures over the period of observation or 3.7 fractures per 100 users per year. Older patients who take multiple medications, have lower bone mineral density, have a history of prior fracture, and suffer from particular comorbidities (i.e., dementia, chronic kidney disease, and rheumatoid arthritis) are at higher risk of fracture while taking bisphosphonates. CONCLUSION: Persistent, current bisphosphonate users remain at risk of fracture, and additional measures to prevent fractures in these patients would be of benefit.

RESUMO

BACKGROUND: Chemoradiation therapy (CRT) has become the mainstay of locally advanced cervical carcinomas (LACC). However, the price to pay is a significant rate of both early and late colo-rectal toxicities, which may impact on survivors' quality of life. To reduce the incidence of such complications, we suggest a simple technique of pelvic radioprotection. MATERIALS AND METHODS: An omental flap is created which is placed to fill the Douglas pouch to both increase the space between rectum and uterine cervix and prevent small bowel to fall in and to be exposed to radiation. In addition, a long sigmoid loop is retracted and fixed in the left paracolic gutter to prevent its irradiation as well. RESULTS: From May 2011 to May 2012, 51 successive LACC patients were offered this procedure in addition of a laparoscopic staging. All but 2 with too small an omentum benefitted from omentoplasty, while sigmoidopexy was performed in all but one patient with a long and free sigmoid loop. No immediate adverse effect was observed. The volume of retro-uterine omental flap averaged 7.17 ± 3.79 cm(3). Sequential measurements of the utero-rectal space throughout CRT duration showed a real and durable increase in the distance between these organs, resulting in a drop in the dose of irradiation to recto-sigmoid. With 10 ± 4.5-month median follow-up, we did not observe any rectal or small bowel early or late adverse effects of CRT. CONCLUSIONS: Although this series is preliminary, this simple procedure, feasible by laparoscopy (or laparotomy), seems effective to prevent recto-sigmoid as well as small bowel from radio-induced complications due to pelvic CRT.

RESUMO

BACKGROUND: We developed a nomogram based on five clinical and pathological characteristics to predict lymph-node (LN) metastasis with a high concordance probability in endometrial cancer. Sentinel LN (SLN) biopsy has been suggested as a compromise between systematic lymphadenectomy and no dissection in patients with low-risk endometrial cancer. METHODS: Patients with stage I-II endometrial cancer had pelvic SLN and systematic pelvic-node dissection. All LNs were histopathologically examined, and the SLNs were examined by immunohistochemistry. We compared the accuracy of the nomogram at predicting LN detected with conventional histopathology (macrometastasis) and ultrastaging procedure using SLN (micrometastasis). RESULTS: Thirty-eight of the 187 patients (20%) had pelvic LN metastases, 20 had macrometastases and 18 had micrometastases. For the prediction of macrometastases, the nomogram showed good discrimination, with an area under the receiver operating characteristic curve (AUC) of 0.76, and was well calibrated (average error =2.1%). For the prediction of micro- and macrometastases, the nomogram showed poorer discrimination, with an AUC of 0.67, and was less well calibrated (average error =10.9%). CONCLUSION: Our nomogram is accurate at predicting LN macrometastases but less accurate at predicting micrometastases. Our results suggest that micrometastases are an 'intermediate state' between disease-free LN and macrometastasis.

RESUMO

BACKGROUND: Based on registries, the European experience has been that <50% of patients are treated according to protocols and/or benefit from the minimum required surgery for ovarian cancer. The French Cancer Plan 2009-2013 considers the definition of qualitative indicators in ovarian cancer surgery in France. This endeavour was undertaken by the French Society of Gynaecologic Oncology (SFOG) in partnership with the French National College of Obstetricians and Gynecologists and all concerned learned societies in a multidisciplinary mindset. METHODS: The quality indicators for the initial management of patients with ovarian cancer were based on the standards of practice determined from scientific evidence or expert consensus. RESULTS: The indicators were divided into structural indicators, including material (equipment), human (number and qualification of staff), and organizational resources, process indicators, and outcome indicators. CONCLUSIONS: The enforcement of a quality assurance programme in any country would undoubtedly promote improvement in the quality of care for ovarian cancer patients and would result in a dramatic positive impact on their survival. Such a policy is not only beneficial to the patient, but is also profitable for the healthcare system.

RESUMO

SUMMARY: The Women's Health Initiative (WHI) double-blind, placebo-controlled clinical trial randomly assigned 36,282 postmenopausal women in the U.S. to 1,000 mg elemental calcium carbonate plus 400 IU of vitamin D(3) daily or placebo, with average intervention period of 7.0 years. The trial was designed to test whether calcium plus vitamin D supplementation in a population in which the use of these supplements was widespread would reduce hip fracture, and secondarily, total fracture and colorectal cancer. INTRODUCTION: This study further examines the health benefits and risks of calcium and vitamin D supplementation using WHI data, with emphasis on fractures, cardiovascular disease, cancer, and total mortality. METHODS: WHI calcium and vitamin D randomized clinical trial (CT) data through the end of the intervention period were further analyzed with emphasis on treatment effects in relation to duration of supplementation, and these data were contrasted and combined with corresponding data from the WHI prospective observational study (OS). RESULTS: Among women not taking personal calcium or vitamin D supplements at baseline, the hazard ratio [HR] for hip fracture occurrence in the CT following 5 or more years of calcium and vitamin D supplementation versus placebo was 0.62 (95 % confidence interval (CI), 0.38-1.00). In combined analyses of CT and OS data, the corresponding HR was 0.65 (95 % CI, 0.44-0.98). Supplementation effects were not apparent on the risks of myocardial infarction, coronary heart disease, total heart disease, stroke, overall cardiovascular disease, colorectal cancer, or total mortality, while evidence for a reduction in breast cancer risk and total invasive cancer risk among calcium plus vitamin D users was only suggestive. CONCLUSION: Though based primarily on a subset analysis, long-term use of calcium and vitamin D appears to confer a reduction that may be substantial in the risk of hip fracture among postmenopausal women. Other health benefits and risks of supplementation at doses considered, including an elevation in urinary tract stone formation, appear to be modest and approximately balanced.

RESUMO

Dysregulation of cathepsin S (Cat S), a cysteine protease involved in extracellular-matrix and basement membrane (BM) degradation, is a concomitant feature of several inflammatory skin diseases. Therefore, Cat S has been suggested as a potential therapeutic target. Flavonoids, which were identified as regulatory molecules of various proteolytic enzymes, exert beneficial effects on skin epidermis. Herein, thirteen flavonoid compounds were screened in vitro and in silico and neohesperidin dihydrochalcone (NHDC) was identified as a potent, competitive, and selective inhibitor (Ki=8±1 µM) of Cat S. Furthermore, Cat S-dependent hydrolysis of nidogen-1, a keystone protein of BM architecture, as well elastin, collagens I and IV was impaired by NHDC, while both expression and activity of Cat S were significantly reduced in NHDC-treated human keratinocytes. Moreover, a reconstructed human skin model showed a significant decrease of both mRNA and protein levels of Cat S after NHDC treatment. Conversely, the expression of nidogen-1 was significantly increased. NHDC raised IL-10 expression, an anti-inflammatory cytokine, and mediated STAT3 signaling pathway, which in turn dampened Cat S expression. Our findings support that NHDC may represent a valuable scaffold for structural improvement and development of Cat S inhibitors to preserve the matrix integrity and favor skin homeostasis during inflammatory events.

RESUMO

PURPOSE: Patients with locally advanced cervical cancer (LACC) are usually treated with concurrent chemoradiotherapy. Extended-field chemoradiotherapy is indicated in case of para-aortic node involvement at initial assessment. 18-Fluoro-2-deoxy-D-glucose positron emission tomography/computed tomography (18-FDG PET/CT) is currently considered to be the most accurate method of detection of node or distant metastases. The goal of this study was to evaluate the accuracy of PET at detecting para-aortic lymph node metastases in LACC patients with a negative morphological imaging. METHODS: Patients from five French institutions with LACC and both negative morphologic (magnetic resonance imaging, CT scan) and functional (PET or PET/CT) findings at the para-aortic level and distantly were submitted to a systematic infrarenal para-aortic node dissection either by laparoscopy or laparotomy. On the basis of pathological results, sensitivity, specificity, and positive and negative predictive values of PET/CT were assessed for para-aortic lymph node involvement. RESULTS: A total of 125 LACC patients (stage IB2-IVA disease with two local recurrences) fulfilled the inclusion criteria. All had an ilio-infrarenal para-aortic lymphadenectomy, either by laparoscopy (n = 117) or laparotomy (n = 8). Twenty-one patients (16.8%) had pathologically proven para-aortic metastases. Among them, 14 (66.7%) had negative PET/CT. Overall morbidity of surgery was 7.2%. All but one of the complications were mild and did not delay chemoradiotherapy. Sensitivity, specificity, and positive and negative predictive value of the PET/CT were 33.3, 94.2, 53.8, and 87.5%, respectively, for the detection of microscopic lymph node metastases. CONCLUSIONS: Laparoscopic staging surgery seems warranted in LACC patients with negative PET scan who are candidates for definitive concurrent chemoradiotherapy or exenteration.

RESUMO

BACKGROUND: Ovarian cancer remains the most lethal gynecologic malignancy with high recurrence rates. Because recurrence involves primarily the peritoneum, intraperitoneal chemotherapy is being evaluated as a new approach to treat microscopic peritoneal disease. One trial showed that cisplatin-paclitaxel intraperitoneal chemotherapy with intravenous paclitaxel improved survival but increased morbidity. Another trial reported a significant improvement in overall survival (OS) and disease-free survival (DFS) without increasing the morbidity (P = 0.76) or mortality rates (hazard ratio 0.67, P = 0.02) after adding hyperthermic intraperitoneal chemotherapy (HIPEC) to interval cytoreduction. The current trial aims to evaluate the impact of adding HIPEC to primary or interval cytoreductive surgery for epithelial ovarian cancer (EOC) on the efficacy, safety, treatment feasibility, and quality of life. PATIENTS AND METHODS: This is an international, multicenter, open-label, randomized (1 : 1), two-arm, phase III clinical trial that will enroll 432 patients with newly diagnosed International Federation of Gynecology and Obstetrics (FIGO) stage III EOC. Patients are randomized to receive or not HIPEC with the standard of care. Inclusion criteria include patients with FIGO stage III EOC, Fallopian tube carcinoma or primary peritoneal cancer who undergo complete primary or interval cytoreduction. The primary objective is to assess DFS of the addition of HIPEC. Secondary objectives are the assessment of OS, safety, return to intended oncologic treatment, quality of life and the trade-off between efficacy and morbidity. CONCLUSIONS: The results might help extend the indications of HIPEC to include patients undergoing primary cytoreduction, providing a standardized protocol for HIPEC in EOC management and reliable information on the quality of life after adding HIPEC.
