RESUMO

INTRODUCTION: The objective of this work is to report the first 6 months of a robotic program in a surgical gynecological team, trained in advanced laparoscopy, in terms of operating times, complication rate, analgesic consumption and average duration of hospitalization. METHODS: This is a prospective observational study, intended to treat. RESULTS: During the study period, 98 women underwent laparoscopic robot assisted surgery. The average BMI was 27.2kg/m2 (±7). Malignant diseases accounted for 41% of operative indications. Comparing the first 30 procedures to the last 30 procedures, there is a significant decrease in docking times: 14.7min (±7.0) vs 8.9min (±5.0), P=0.009. There is also a trend towards a decrease in operative times for hysterectomy: 151.9min (±56.2) vs 113min (±51.4), P=0.08. The rates of complications were not significantly different at the beginning and end of inclusion during the study (10.0% vs 16.7%). CONCLUSION: The implementation of a robotic surgery program in a gynecological surgery department does not lead to an increase in complications for the patients, including for the first procedures. The learning curve mainly allows a reduction in the robot's installation time.

RESUMO

Rose is the world's most important ornamental plant, with economic, cultural and symbolic value. Roses are cultivated worldwide and sold as garden roses, cut flowers and potted plants. Roses are outbred and can have various ploidy levels. Our objectives were to develop a high-quality reference genome sequence for the genus Rosa by sequencing a doubled haploid, combining long and short reads, and anchoring to a high-density genetic map, and to study the genome structure and genetic basis of major ornamental traits. We produced a doubled haploid rose line ('HapOB') from Rosa chinensis 'Old Blush' and generated a rose genome assembly anchored to seven pseudo-chromosomes (512 Mb with N50 of 3.4 Mb and 564 contigs). The length of 512 Mb represents 90.1-96.1% of the estimated haploid genome size of rose. Of the assembly, 95% is contained in only 196 contigs. The anchoring was validated using high-density diploid and tetraploid genetic maps. We delineated hallmark chromosomal features, including the pericentromeric regions, through annotation of transposable element families and positioned centromeric repeats using fluorescent in situ hybridization. The rose genome displays extensive synteny with the Fragaria vesca genome, and we delineated only two major rearrangements. Genetic diversity was analysed using resequencing data of seven diploid and one tetraploid Rosa species selected from various sections of the genus. Combining genetic and genomic approaches, we identified potential genetic regulators of key ornamental traits, including prickle density and the number of flower petals. A rose APETALA2/TOE homologue is proposed to be the major regulator of petal number in rose. This reference sequence is an important resource for studying polyploidization, meiosis and developmental processes, as we demonstrated for flower and prickle development. It will also accelerate breeding through the development of molecular markers linked to traits, the identification of the genes underlying them and the exploitation of synteny across Rosaceae.

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

Epithelial ovarian cancer (EOC) affects 4500 women a year in France, with a survival of 30% at 5 years. Treatment is based on extensive surgery and chemotherapy. Around 15% of EOCs are due to genetic mutation predisposition essentially with mutated BRCA1 and BRCA2 genes. Four histological subtypes are described (serous, endometrioid, and mucinous cells to clear), corresponding to different carcinogenesis and distinct molecular mutations. High-grade serous EOCs have a mutation of the BRCA genes in 20-30% of cases. This mutation causes a deficit of repair by homologous recombination of DNA in case of double strand break, allowing greater sensitivity to platinum salts and the use of PARP inhibitors, a protein involved in the repair of single-strand breaks of DNA. PARP inhibitors have shown efficacy in patients mutated BRCA but this effectiveness remains to be demonstrated in patients without congenital mutation, but with acquired BRCAness profile EOC. The BRCAness profile is defined by a tumor having a defect in DNA repair counterpart (not limited to BRCA mutation). Molecular definition of BRCAness is still not consensual but is necessary for the use of PARP inhibitors. Gene expression analyses have identified four subgroups of high-grade serous CEO: mesenchymal, proliferative, differentiated and immunoreactive. These four subtypes, not mutually exclusive, although correlated with prognosis, are not yet used in clinical routine.

RESUMO

OBJECTIVE: This study aims to evaluate the different surgical approaches, perioperative morbidity and surgical staging according to age in patients with endometrial cancer. METHODS: Multicentre retrospective study. Cancer characteristics and perioperative data were collected for patients surgically treated for endometrial cancer. The patients were divided into 2 groups according to their age: younger or older than 75 years. RESULTS: Surgery was performed on 270 women <75 years old and on 74 ≥ 75 years old. Minimally invasive surgery was performed less often in the elderly compared with their younger counterparts (58.2% vs. 74.8%; p = 0.006). Independently of the surgical approach, the rate of pelvic and para-aortic lymphadenectomy was lower in women older than 75 years old than their younger counterparts (52.7% vs. 74.8%; p < 0.001; 8.1% vs. 21.8%; p = 0.007 respectively). According to the guidelines, more frequent surgical understaging was seen in the elderly compared with the younger (37% vs. 15.2%; p = 0.002). In the comparison of complications for each surgical approach, there was no statistical difference in the ≥75-year-old age group in terms of intra- or postoperative complications between the laparotomy, laparoscopy or robotic surgery group. We found a shorter length of hospital stay for the women who underwent laparoscopy or robotic surgery compared with laparotomy (p < 0.0001). CONCLUSION: Elderly women with endometrial cancer are often surgically understaged whereas there is no evidence of greater perioperative complications than for their younger counterparts. They should benefit from minimally invasive surgery and optimal surgical staging to the same extent as younger women.

RESUMO

OBJECTIVE: The purpose of this review is to assess the preoperative management in case of recurrent cervical cancer, to assess patients for a surgical curative treatment. METHODS: English publications were searched using PubMed and Cochrane Library. RESULTS: In the purpose of curative surgery, pelvic exenteration required clear margins. Today, only half of pelvic exenteration procedures showed postoperative clear margins. Modern imaging (RMI and Pet-CT) does not allow defining local extension of microcopic disease, and thus postoperative clear margins. Despite the same generic term of pelvic exenteration, there is a wide heterogeneity in surgical procedures in published cohorts. CONCLUSION: Because clear margins are required for curative pelvic exenteration, but are not predictable by preoperative assessment. The larger surgery, i.e. the infra-elevator exenteration with vulvectomy, could be the logical surgical choice to increase the rate of clear margins and therefore, recurrent cervical carcinoma patient survival.

RESUMO

OBJECTIVE: To assess the use of French Cancer Institute recommendations for the diagnosis and treatment of endometrial cancer. METHODS: Retrospective observational study involving 137 patients with endometrial cancer between 2011 and 2013. RESULTS: Both MRI and pathological assessment with correct report as recommended were used for 66.4% of patients with endometrial cancer. For patients with correct preoperative assessment, 44.9% of patients were uncorrectly classified and upgraded on final pathological analysis of hysterectomy concerning lymph node involvement risk. These patients did not have confident surgical assessment, according this risk. CONCLUSION: To improve relevance of preoperative assessment in endometrial cancer, radiological and pathological expertise is required. However, even performed optimally, preoperative assessment does not allow correct risk stratification of lymph node involvement in endometrial cancer. This ineffective stratification leads to propose sentinel lymph node biopsy with hysterectomy in case of preoperative low risk endometrial cancer assessment.

RESUMO

OBJECTIVE: Endometrial cancer primarily affects elderly women. The aim of the present literature review is to define the population of elderly women with this disease and to define the characteristics of this cancer in elderly people as well as its surgical treatment. MATERIALS AND METHODS: A systematic review of the English-language literature of the last 20 years indexed in the PubMed database. RESULTS: Endometrial cancer is more aggressive in elderly women. However, surgical staging performed in elderly patients is often not concomitant with the disease's aggressiveness in this group. Mini-invasive surgery is performed less often, for no obvious reason. Of note, oncogeriatric evaluation was not usually ruled out to determine the most appropriate surgical modality. CONCLUSION: Studies are needed to evaluate surgical management of endometrial cancer in elderly women, notably with the aid of oncogeriatric scores to predict surgical morbidity.

RESUMO

OBJECTIVE: Pelvic exenteration requires complete resection of the tumor with negative margins to be considered a curative surgery. The purpose of this review is to assess the optimal preoperative evaluation and surgical approach in patients with recurrent cervical cancer to increase the chances of achieving a curative surgery with decreased morbidity and mortality in the era of concurrent chemoradiotherapy. METHODS: Review of English publications pertaining to cervical cancer within the last 25 years were included using PubMed and Cochrane Library searches. RESULTS: Modern imaging (MRI and PET-CT) does not accurately identify local extension of microscopic disease and is inadequate for preoperative planning of extent of resection. Today, only half of pelvic exenteration procedures obtain uninvolved surgical margins. CONCLUSION: Clear margins are required for curative pelvic exenterations, but are poorly predictable by pre-operative assessment. More extensive surgery, i.e. the infra-elevator exenteration with vulvectomy, is a logical surgical choice to increase the rate of clear margins and to improve patient survival following surgery for recurrent cervical carcinoma.

RESUMO

INTRODUCTION: Epithelial ovarian carcinoma (EOC) has a worst prognosis with little progress in terms of survival for the last two decades. Immunology received little interest in EOC in the past, but now appears very important in the natural history of this cancer. This review is an EOC immunology state of art and focuses on the place of immunotherapy in future. MATERIAL AND METHODS: A systematic review of published studies was performed. Medline baseline interrogation was performed with the following keywords: "Ovarian carinoma, immunotherapy, T-lymphocyte, regulator T-lymphocyte, dendritic cells, macrophage, antigen, chemotherapy, surgery, clinical trials". Identified publications (English or French) were assessed for the understanding of EOC immunology and the place of conventional treatment and immunotherapy strategy. RESULTS: Intratumoral infiltration by immune cells is a strong prognotic factor in EOC. Surgery and chemotherapy in EOC decrease imunosuppression in patients. The antitumoral immunity is a part of the therapeutic action of surgery and chemotherapy. Until now, immunotherapy gave some disappointing results, but the new drugs that target the tolerogenic tumoral microenvironnement rise and give a new hope in the treatment of cancer. CONCLUSION: Immunology controls the EOC natural history. The modulation of immunosuppressive microenvironment associated with the stimulation of antitumoral immunity could be the next revolution in the treatment of cancer.

RESUMO

INTRODUCTION: The adenocarcinoma of the uterine cervix accounts for 10 to 20% of the premalignant and malignant lesions and is different from the cervical intraepithelial neoplasia and invasive squamous cell carcinoma. MATERIALS AND METHODS: Recent literature review (from 1985 to 2012) based on the literature available. RESULTS AND DISCUSSION: Adenocarcinoma in situ is an induced HPV lesion (role of HPV 18) of the glandular epithelium: its preferential endocervical situation explains the difficulties in the diagnosis and follow-up after conservative treatment. If the hysterectomy remains the gold standard for treatment, the conservative treatments (resection in sano of the lesions with margins of more than 1cm, meticulous study of the operative specimen, compliance with the follow-up) are possible in the young patients who desire to preserve their fertility. The invasive adenocarcinoma is characterized by a more difficult diagnosis because of its endocervical development, and a prognosis less favorable when compared to squamous cell carcinoma with a greater frequency of the lymphatic node involvement and metastatic diffusion. Its treatment must take into account the particular gravity of the factors of worse prognosis (FIGO stage, tumor size, lymphatic node spreading, adenosquamous histological subtype) in particular in the advanced stages and includes beside the surgery, radiotherapy and chemotherapy.

RESUMO

INTRODUCTION: The treatment of locally advanced cervical carcinoma of uterine cervix is based on concurrent chemoradiotherapy (CCR). The role of laparoscopic lymphadenectomy before CCR and hysterectomy after CCR is not consensual. PATIENTS AND METHODS: Retrospective multicentric study on 102 patients treated for locally advanced carcinoma of uterine cervix between 1999 and 2008. Disease-free survival and overall survival (OS) were studied. RESULTS: Stages were: stage IB 42%, II 47% and stage III and IVA 11%. All patients received CCR. Eighty-one patients had associated brachytherapy. Sixty-two patients underwent laparoscopic lymphadenectomy before CCR and 31 patients had also para-aortic lymphadenectomy. Eighty-two patients had hysterectomy after CCR. Forty-seven percent (29/62) of patients had a histologically proven pelvic lymph node involvement and 58% (18/31) had a histologically proven para-aortic lymph node involvement. There is no predictor of the presence of residual tumor on hysterectomy. The lymph node involvement before treatment and the presence of residual tumor on hysterectomy were poor prognostic factors on relapse-free survival (SSR) and OS. It has not been shown to benefit from surgery pre- or post-CCR on survival. CONCLUSION: Surgery can provide major prognosis factor and especially lymphadenectomy before CCR can improve the therapeutic strategy but does not demonstrate significant survival benefit.

RESUMO

INTRODUCTION: The diagnosis of atypical epithelial hyperplasia (AEH) increases with breast cancer screening. AEH is divided in three groups: atypical ductal hyperplasia, columnar cell lesions with atypia, lobular neoplasia. The management of women with AEH is not consensual because of uncertainty about their diagnosis related to the type of the biopsy sampling (core needle biopsy or surgical excision) and their controversial clinical signification between risk marker and true precursor of breast cancer. MATERIAL AND METHODS: A systematic review of published studies was performed. Medline baseline interrogation was performed with the following keywords: atypical ductal hyperplasia, columnar cell lesions with atypia, lobular neoplasia, core needle biopsy, breast cancer, precursor lesion, hormonal replacement therapy. For each breast lesion, identified publications (English or French) were assessed for clinical practise in epidemiology, diagnosis and patient management. RESULTS: With immunohistochemistry and molecular studies, AEH seems to be precursor of breast cancer. But, epidemiological studies show low rate of breast cancer in women with AEH. AEH were still classified as risk factor of breast cancer. CONCLUSION: Because of high rate of breast cancer underestimation, surgical excision is necessary after the diagnosis of AEH at core needle biopsy. Surgical oncology rules and collaboration with radiologist are required for this surgery. A second operation was not required due to involved margins by AEH (except with pleiomorphic lobular neoplasia) because local control of breast cancer seems to be unchanged. Besides, hormonal replacement therapy for patient with AEH is not recommended because of lack of studies about this subject.

RESUMO

INTRODUCTION: The cancer of the cervix annually occurs in 150 women in Brittany in the absence of organized screening. MATERIAL AND METHODS: Retrospective study concerning 191 patients treated for an invasive cancer of the uterine cervix between 2000 and 2005 analyzing their cytological past. The average age of the patients was 52 years (22-87 years). The socioeconomic level of the patients was recorded. The distribution of under histological types was: squamous, 73% (54 years average age) and adenocarcinoma, 22% (average age 47 years). All the stages were represented: stage I 46%, II 32%, III 9% and stage IV 13%. RESULTS: Cancer was symptomatic in 89% of the cases and 72% of the patients had not profited from cytological screening according to French recommendations (50% no follow-up, 22% follow-up between three and 10 years), while 28% of the patients had a smear in the three years. The socioeconomic level of the patients strongly influenced the participation in screening. The proportion of patients having an invasive adenocarcinom was 31% in the patients with a smear going back to less than three years (versus 22% in our total population) and this histological subtype was mainly represented in patients less than 35 years old (35%). Lastly, 2,6% of the patients were lost after realization of a pathological smear. CONCLUSION: The extension of screening and its organization remain a priority in our area. The average sensitivity of the smear is illustrated by the on-representation of the adenocarcinoma, in particular among young women.

RESUMO

PURPOSE: The authors describe and evaluate the management system for patients requiring large core vacuum-assisted biopsies at a dedicated breast center. This process includes mandatory review of all requests by a multidisciplinary team. MATERIAL: and method. Patients were provided questionnaires to evaluate their degree of satisfaction with the management process. Results from biopsy and surgery were retrospectively reviewed. RESULTS: From the 100 patients included in the study (106 macrobiopsies), 95,28% of biopsies were informative. The degree of correlation between the histological diagnosis from biopsy and surgery was 86,95% for the 46 operated cases. The degree of acceptability by patients as well as medical and non-medical staff was satisfactory. CONCLUSION: The original feature of this process is the retrospective review of all charts after the histological results becomes available for final validation of the biopsy results and management. The results of the biopsy and the post biopsy management are provided by the initial referring physician, allowing optimal patient care and follow-up.

RESUMO

The molecular mechanisms of de novo meristem formation, cell differentiation and the integration of the cell cycle machinery into appropriate stages of the developmental programmes are still largely unknown in plants. Legume root nodules, which house nitrogen-fixing rhizobia, are unique plant organs and their development may serve as a model for organogenetic processes in plants. Nodules form and are essential for the plant only under limitation of combined nitrogen in the soil. Moreover, their development is triggered by external mitogenic signals produced by their symbiotic partners, the rhizobia. These signals, the lipochitooligosaccharide Nod factors, act as host-specific morphogens and induce the re-entry of root cortical cells into mitotic cycles. Maintenance of cell division activity leads to the formation of a persistent nodule meristem from which cells exit continuously and enter the nodule differentiation programme, involving multiple cycles of endoreduplication and enlargement of nuclear and cell volumes. While the small diploid 2C cells remain uninfected, the large polyploid cells can be invaded and, after completing the differentiation programme, host the nitrogen-fixing bacteroids. This review summarizes the present knowledge on cell cycle reactivation and meristem formation in response to Nod factors and reports on a novel plant cell cycle regulator that can switch mitotic cycles to differentiation programmes.

RESUMO

A 33-year-old woman underwent a myomectomy via coelioscopy and then showed 5 years later a uterine rupture at the 32nd week of amenorrhea. The rupture was diagnosed after the echography, while there was no peritoneal maternal patency nor foetal consequence. After a cesarean and an uterine repair, the recovery of the mother was satisfactory but the newborn was to die at the 6th week of life. This obstetrical complication raises the problem of myomectomy via coelioscopy in young women, whose indications are being discussed.

RESUMO

Polyamines are involved in the development of breast cancer. We assayed polyamines in erythrocytes, urines, and breast tissues (tumor tissue and histologically normal breast tissue close to the tumor) of patients with invasive breast cancer (n = 174) and benign breast disease (n = 71, used as controls). Polyamine levels in red blood cells and urine were similar to the polyamine concentrations found in healthy subjects, and thus cannot be used as diagnostic markers of breast cancer. In cancer tissue, polyamines were significantly increased in comparison with the polyamine concentrations in controls, and were correlated to the tumor aggressiveness as evaluated by histological grade and Ki-67 proliferative index. On the other hand, correlation was found between polyamine levels in the tumor and the status of the hormone receptors. In the mammary tissue close to the cancer, polyamines dramatically decreased in comparison with the polyamine levels of tissue samples removed around the histologically proven benign tumors. The changes of the polyamine concentrations in the histologically normal breast tissue in the vicinity of the cancer could play a role in the cancer development and need further studies, especially if polyamines are considered as a potential therapeutic target in breast cancer.

RESUMO

Polyamines are ubiquitous cellular compounds which are required for estradiol induced proliferation in breast cancer. Complete polyamine deprivation, using 2 alpha-difluoromethyl-ornithine (DFMO, Eflornithine), a specific inactivator of ornithine decarboxylase (key-enzyme of the polyamine biosynthesis) combined with inhibition of the bacterial production of gastrointestinal polyamine and a polyamine free regimen, was demonstrated to exhibit a cytostatic effect and a decrease of the three tumoral polyamine concentrations in a MCF-7 tumor model. In this experiment, complete polyamine deprivation has been tested on a standard MCF-7 tumor and on a variant MCF-7 tumor (i.e. with a tamoxifen acquired resistance). Polyamine deprivation was effective on the tumor growth, both on standard and variant sub-types. The polyamine contents of two types of tumor were similar, and identically, polyamine deprivation has caused a decrease of putrescine, spermidine and also spermine tumoral concentrations measured by the HPLC method in standard and variant MCF-7 tumors. Acquired tamoxifen resistance is common in patients undergoing hormonal therapy for advanced breast cancer. It has been hypothesized that the direct stimulation of polyamine pathway without estradiol involvement could be one of the mechanisms responsible for the tamoxifen resistance. The ability of polyamine deprivation to inhibit the growth of tumors becoming tamoxifen resistant could offer a therapeutic advantage in case of tumor with acquired tamoxifen resistance and could be tested to prevent or delay the hormonal responsiveness to breast cancer.

RESUMO

BACKGROUND: Prognosis factors for adenocarcinoma of the uterine cervix after primary treatment are poorly established. METHODS: A retrospective study of 45 cases of adenocarcinoma of the cervix with a follow-up of 96 months on average was performed. The primary treatment consisted in combined radical surgery and radiotherapy for stage I-II patients while patients with advanced disease were treated by radiotherapy. In case of poor prognosis factors, they were given chemotherapy. Survival rates were established and prognosis factors influencing survival and recurrences were studied. RESULTS: Fifteen women remained alive without evolutive disease. FIGO stage and pelvic node involvement were the most important parameters influencing overall survival. Local failures (27%, average period of 30 months) were unpredictable and led to a dramatic outcome. Histological grade and pelvic node status were significant predictive factors for metastatic recurrence (40%, average period of 29 months). CONCLUSIONS: Local recurrence and metastatic dissemination of cervical adenocarcinoma after primary treatment prove to be rapidly fatal although life expectancy can be prolonged with adjuvant treatment of the recurrence. In the event of aggressive tumors with high histological grade and pelvic node involvement, an attempt to assess adjuvant systemic chemotherapy could be useful.
