RESUMO
PURPOSE: The present knowledge about lymphatic drainage of the ovary is based on carcinological studies, but it has only rarely been studied under physiological conditions. However, it is one of the preferential routes of dissemination in ovarian cancer, and understanding it is therefore vital for optimal carcinological management.Our purpose was to evaluate the feasibility of an innovative technique to study the lymphatic drainage territories of the ovary using a recirculation module on the cadaveric model. METHODS: We injected patent blue into the cortex of twenty "revascularised" cadaver ovaries with the Simlife recirculation model. We observed the migration of the dye live and described the drainage territories of each ovary. RESULTS: We observed a staining of the lymphatic vessels and migration of the dye in all the subjects, systematically ipsilateral to the injected ovary. We identified a staining of the lumbo-aortic territory in 65% of cases, with a preferential lateral-caval involvement (60%) for the right ovary and lateral-aortic territory (40%) for the left ovary. A common iliac involvement was observed in only 10% of cases. In 57% of cases, the staining of the lumbo-aortic territory was associated with a staining of the suspensory ligament. The pelvic territory was involved in 50% of cases, with an external iliac staining in 25% of cases and internal in 20%. CONCLUSION: Our study provides for a better understanding of lymphatic drainage of the ovary using a new detection method, and allows the possibility of improving the teaching for operators with a realistic model. Continuation of this work could lead to considering more targeted and thus less morbid lymph node sampling for lymph node staging in early-stage ovarian cancer.

ABSTRACT: Tumor-associated macrophages are targets of interest in triple-negative breast cancer (TNBC). The translocator protein 18 kDa (TSPO) is a sensitive marker for macrophages and holds potential relevance in TNBC stratification. This pilot prospective study (EITHICS, NCT04320030) aimed to assess the potential of TSPO PET/CT imaging using 18 F-DPA-714 in primary TNBC, compared with immunohistochemistry, autoradiography, and TSPO polymorphism. PATIENTS AND METHODS: Thirteen TNBC patients were included. They underwent TSPO genotyping (HAB, MAB, LAB), 18 F-FDG PET/CT, and breast MRI. Semiquantitative PET parameters were computed. VOIs were defined on the tumor lesion, healthy breast tissue, and pectoral muscle to obtain SUV, tumor-to-background ratio (TBR), and time-activity curves (TACs). Additionally, immunohistochemistry, 3 H-DPA-714, and 3 H-PK-11195 autoradiography were conducted. RESULTS: The majority of TNBC tumors (11/13, 84%) had a preponderance of M2-polarized macrophages with a median proportion of 82% (range, 44%-94%). 18 F-DPA-714 PET/CT clearly identified TNBC tumors with an excellent TBR. Three distinct patterns of 18 F-DPA-714 TACs were identified, categorized as "above muscular," "equal to muscular," and "below muscular" with reference to the muscular background. For the "above muscular" group (2 HAB and 2 MAB), "equal muscular" group (3 HAB, 3 MAB, and 1 LAB), and "below muscular" group (1 LAB and 1 MAB), tumor TACs showed a 18 F-DPA-714 accumulation slope of 1.35, 0.62, and 0.22, respectively, and a median SUV mean of 4.02 (2.09-5.31), 1.66 (0.93-3.07), and 0.61 (0.43-1.02). CONCLUSIONS: This study successfully demonstrated TNBC tumor targeting by 18 F-DPA-714 with an excellent TBR, allowing to stratify 3 patterns of uptake potentially influenced by the TSPO polymorphism status. Further studies in larger populations should be performed to evaluate the prognostic value of this new biomarker.

BACKGROUND: In women, ovarian cancer is the eighth most frequent cancer in incidence and mortality. It is often diagnosed at advanced stages; relapses are frequent, with a poor prognosis. When platinum resistant, subsequent lines of chemotherapy are of limited effect and often poorly tolerated, leading to quality of life deterioration. Various studies suggest a hormonal role in ovarian carcinogenesis, with a rationale for endocrine therapy in these cancers. PATIENTS AND METHODS: This multicenter, retrospective study assessed the use of endocrine treatment for high-grade ovarian epithelial carcinomas treated between 2010 and 2020. RESULTS: Eighty-one patients with ovarian cancers were included. The median duration of platinum sensitivity was 29 months. We observed a 35% disease control rate with endocrine therapy, and 10% reported symptom improvement. For 19 patients (23.5%), the disease was stabilized for more than 6 months. Median overall survival from diagnosis was 62.6 months. Regarding endocrine therapy predictive factors of response, in a multivariate analysis, 3 factors were statistically significant in favoring progression-free survival: platinum sensitivity (Pâ =â .021), an R0 surgical resection (Pâ =â .020), and the indication for hormone therapy being maintenance therapy (Pâ =â .002). CONCLUSION: This study shows real-life data on endocrine therapy in ovarian cancer. As it is a low-cost treatment with many advantages such as its oral administration and its safety, it may be an option to consider. A perspective lies in the search for cofactors to aim as future therapeutic targets to improve the effectiveness of hormone treatment by means of combination therapy.

Epithelial ovarian cancer is mostly discovered at the stage of peritoneal carcinosis. Complete cytoreductive surgery improves overall survival. The Fagotti score is a predictive score of resectability based on peritoneal laparoscopic exploratory. Our aim was to study the inter-observer concordance in an external validation of the Fagotti score. An observational, prospective, multicenter study was conducted using the Francogyn research network. The primary outcome was inter-observer concordance of the Fagotti score. 15 patients in which an ovarian mass was discovered were included. For each patient, the first exploratory laparoscopy before any treatment/chemotherapy was recorded. This bank of 15 videos was subject to blind review accompanied by a Fagotti score rating by 11 gynecological surgeons specializing in oncology. A total of 165 blind reviews were performed. Inter-observer concordance was very good for the Fagotti score with an intraclass correlation coefficient (ICC) of 0.83 [95% CI 0.71; 0.93]. Inter-observer concordance for the adjusted Fagotti score, which accounts for unexplorable areas with extensive carcinomatosis, resulted in an ICC of 0.64 [95% CI 0.46; 0.82]. According to the reviewers, the three least explorable parameters were mesentery involvement, stomach infiltration and liver damage. The ICC of the explorable Fagotti score, i.e. score with deletion of the parameters most often unexplored by laparoscopy, was 0.86 [0.75-0.94]. This study confirms the reproducibility of the Fagotti score during first assessment laparoscopies in cases of advanced ovarian cancer. The explorable Fagotti score has an equivalent or better inter-observer concordance than the Fagotti score.

SK3 channels are potassium channels found to promote tumor aggressiveness. We have previously demonstrated that SK3 is regulated by synthetic ether lipids, but the role of endogenous ether lipids is unknown. Here, we have studied the role of endogenous alkyl- and alkenyl-ether lipids on SK3 channels and on the biology of cancer cells. Experiments revealed that the suppression of alkylglycerone phosphate synthase or plasmanylethanolamine desaturase 1, which are key enzymes for alkyl- and alkenyl-ether-lipid synthesis, respectively, decreased SK3 expression by increasing micro RNA (miR)-499 and miR-208 expression, leading to a decrease in SK3-dependent calcium entry, cell migration, and matrix metalloproteinase 9-dependent cell adhesion and invasion. We identified several ether lipids that promoted SK3 expression and found a differential role of alkyl- and alkenyl-ether lipids on SK3 activity. The expressions of alkylglycerone phosphate synthase, SK3, and miR were associated in clinical samples emphasizing the clinical consistency of our observations. To our knowledge, this is the first report showing that ether lipids differentially control tumor aggressiveness by regulating an ion channel. This insight provides new possibilities for therapeutic interventions, offering clinicians an opportunity to manipulate ion channel dysfunction by adjusting the composition of ether lipids.

No data are currently available on the functional role of small conductance Ca2+-activated K+ channels (SKCa) in ovarian cancer. Here, we characterized the role of SK2 (KCa2.2) in ovarian cancer cell migration and chemosensitivity. Using the selective non-cell-permeant SK2 inhibitor Lei-Dab7, we identified functional SK2 channels at the plasma membrane, regulating store-operated Ca2+ entry (SOCE) in both cell lines tested (COV504 and OVCAR3). Silencing KCNN2 with short interfering RNA (siRNA), or blocking SK2 activity with Lei-Dab7, decreased cell migration. The more robust effect of KCNN2 knockdown compared to Lei-Dab7 treatment suggested the involvement of functional intracellular SK2 channels in both cell lines. In cells treated with lysophosphatidic acid (LPA), an ovarian cancer biomarker of progression, SK2 channels are a key player of LPA pro-migratory activity but their role in SOCE is abolished. Concerning chemotherapy, SK2 inhibition increased chemoresistance to Taxol® and low KCNN2 mRNA expression was associated with the worst prognosis for progression-free survival in patients with serous ovarian cancer. The dual roles of SK2 mean that SK2 activators could be used as an adjuvant chemotherapy to potentiate treatment efficacy and SK2 inhibitors could be administrated as monotherapy to limit cancer cell dissemination.

OBJECTIVES: Describing the constitution of the FRANCOGYN group (a national French research group in Oncological and Gynecological Surgery) and present its current and future development. METHODS: Literature review using PUBMed database with the keyword "FRANCOGYN". OBJECTIVES: Describing the constitution of the FRANCOGYN group (a national French research group in Oncological and Gynecological Surgery) and present its current and future development. RESULTS: The FRANCOGYN group was formed in December 2015, bringing together over the years more than 17 gynecological and oncological surgical department in France. The group carries out clinical research on gynecological pelvic cancers by constituting retrospective cohorts. Its legitimacy allows it to lead or co-lead the drafting of recommendations for clinical practice in the field of gynecological cancers. It now offers prospective randomized research funded by national grants. CONCLUSION: The FRANCOGYN network allows us to propose a national reflection on the surgical management of pelvic cancers in women, resulting in numerous international reference publications.

OBJECTIVE: Evaluation of the management by first brachytherapy followed by radical hysterectomy (Wertheim type) compared to radical hysterectomy alone (Wertheim type) for the treatment of IB2 cervical cancer. METHODS: Data from women with histologically proven FIGO stage IB2 cervical cancer treated between April 1996 and December 2016 were retrospectively abstracted from twelve French institutions with prospectively maintained databases. RESULTS: Of the 211 patients with FIGO stage IB2 cervical cancer without lymph node involvement included, 136 had surgical treatment only and 75 had pelvic lymph node staging and brachytherapy followed by surgery. The surgery-only group had significantly more adjuvant treatment (29 vs. 3; p = 0.0002). A complete response was identified in 61 patients (81%) in the brachytherapy group. Postoperative complications were comparable (63,2% vs. 72%, p = 0,19) and consisted mainly of urinary (36vs. 27) and digestive (31 vs 22) complications and lymphoceles (4 vs. 1). Brachytherapy had no benefit in terms of progression-free survival (p = 0.14) or overall survival (p = 0.59). However, for tumors of between 20 and 30 mm, preoperative brachytherapy improved recurrence-free survival (p = 0.0095) but not overall survival (p = 0.41). This difference was not observed for larger tumors in terms of either recurrence-free survival (p = 0.55) or overall survival (p = 0.95). CONCLUSION: Our study found that preoperative brachytherapy had no benefit for stage IB2 cervical cancers in terms of recurrence-free survival or overall survival. For tumor sizes between 2 and 3 cm, brachytherapy improves progression-free survival mainly by reducing pelvic recurrences without improving overall survival.

OBJECTIVES: Obesity is known to be both a major risk factor for endometrial cancer and associated with surgical complexity. Therefore, the management of patients with obesity is a challenge for surgeons and oncologists. The aim of this study is to assess the adherence to European Society of Gynaecological Oncology (ESGO) guidelines in morbidly obese patients (body mass index (BMI) >40 kg/m2). The secondary objectives were the impact on overall survival and recurrence-free survival. METHODS: All the patients who were treated for an endometrial cancer in the 11 cancer institutes of the FRANCOGYN group were included and classified into three weight groups: morbid (BMI >40 kg/m2), obese (BMI 30-40), and normal or overweight (BMI <30). Adherence to guidelines was evaluated for surgical management, lymph node staging, and adjuvant therapies. RESULTS: In total, 2375 patients were included: 1330 in the normal or overweight group, 763 in the obese group, and 282 in the morbid group. The surgical management of the morbid group was in accordance with the guidelines in only 30% of cases, compared with 44% for the obese group and 48% for the normal or overweight group (p<0.001); this was largely because of a lack of lymph node staging. Morbid group patients were more likely to receive the recommended adjuvant therapy (61%) than the obese group (52%) or the normal or overweight group (46%) (p<0.001). Weight had no impact on overall survival (p=0.6) and morbid group patients had better recurrence-free survival (p=0.04). CONCLUSION: Adherence to international guidelines for surgical management is significantly lower in morbid group patients, especially for lymph node staging. However, morbidly obese patients had more often the adequate adjuvant therapies. Morbid group patients had a better recurrence-free survival likely because of better prognosis tumors.

BACKGROUND: Grade 1 breast cancer represents the lowest grade of invasive breast cancer and is associated with a low risk of recurrence and distant metastasis. However, when grade 1 breast cancer is associated with lymph node involvement, the prognosis may be worse than that of grade 1 breast cancer without lymph node involvement. METHOD: The study population included all patients who were managed in our institution between January 1, 2007 and December 31, 2013 for grade 1 breast cancer . We compared patients who had lymph node involvement to those who had no lymph node involvement. RESULTS: During the study period 291 grade 1 carcinomas were included of which 23% had associated positive lymph node involvement. Overall survival did not differ significantly between patients without lymph node involvement and those with lymph node involvement, nor was there a significant difference in the risk of local recurrence free survival. However, a significant difference was found in survival without distant metastasis with a significant level of a p at 0.029. CONCLUSION: Our findings confirm that tumor size and LVSI are strong predictors of axillary lymph node involvement, which is a key determinant of distant metastasis-free survival.

OBJECTIVE: To compare survival and morbidity rates between primary cytoreductive surgery (pCRS) and interval cytoreductive surgery (iCRS) for epithelial ovarian cancer (EOC), using a propensity score. DESIGN: We conducted a propensity score-matched cohort study, using data from the FRANCOGYN cohort. SETTING: Retrospective, multicentre study of data from patients followed in 15 French department specialized in the treatment of ovarian cancer. SAMPLE: Patients included were those with International Federation of Gynaecology and Obstetrics (FIGO) stage III or IV EOC, with peritoneal carcinomatosis, having undergone CRS. METHODS: The propensity score was designed using pre-therapeutic variables associated with both treatment allocation and overall survival (OS). MAIN OUTCOME MEASURES: The primary outcome was OS. Secondary outcomes included recurrence-free survival (RFS), quality of CRS and other variables related to surgical morbidity. RESULTS: A total of 513 patients were included. Among these, 334 could be matched, forming 167 pairs. No difference in OS was found (hazard ratio, HR = 0.8, p = 0.32). There was also no difference in RFS (median = 26 months in both groups) nor in the rate of CRS leaving no macroscopic residual disease (pCRS 85%, iCRS 81.4%, p = 0.76). The rates of gastrointestinal tract resections, stoma, postoperative complications and hospital stay were significantly higher in the pCRS group. CONCLUSIONS: Analysis of groups of patients made comparable by propensity score matching showed no difference in survival, but lower postoperative morbidity in patients treated with iCRS.
RESUMO
International Federation of Gynecology and Obstetrics (FIGO) staging classification for stage IV epithelial ovarian cancer (EOC) separates stages IVA (pleural effusion) and IVB (parenchymal and/or extra-abdominal lymph node metastases). We aimed to evaluate its prognostic impact and to compare survival according to the initial metastatic location. We conducted a multicenter study between 2000 and 2020, including patients with a FIGO stage IV EOC. Primary endpoint was overall survival (OS). The secondary endpoints were progression-free survival (PFS) and recurrence rates. We included 307 patients: 98 (32%) had FIGO stage IVA and 209 (68%) had FIGO stage IVB. The median OS and PFS of stage IVA patients were significantly lower than those of stage IVB patients (31 versus 45 months (p = 0.02) and 18 versus 25 months (p = 0.01), respectively). Recurrence rate was higher in stage IVA than IVB patients (65% versus 47% (p = 0.004)). Initial pleural involvement was a poor prognostic factor with a median OS of 35 months versus 49 months for patients without initial pleural involvement (p = 0.024). Patients with FIGO stage IVA had a worse prognosis than patients with FIGO stage IVB EOC. Pleural involvement appears to be relevant for predicting survival. We suggest a modification of the current FIGO staging classification.
RESUMO
Prognostic factors for epithelial ovarian cancers (EOCs) are in particular clinical factors such as pathology staging at diagnosis (FIGO stages), genetic mutation, or histological phenotypes. In the present study, FIGO stage, tumor residue after surgery, and body mass index were clinical predictors of recurrence-free survival (RFS). Nonetheless, a number of studies support a lipid metabolism disorder in ovarian cancer patients. The objective of this pilot study was to explore whether fatty acid composition of adipose reflecting the qualitative dietary intake and fatty acids metabolism may be associated with RFS. Forty-six women with EOCs and six with borderline ovarian tumors between March 2017 and January 2020 were included in this prospective study at Tours university teaching hospital (central France). The patients involved in the present study are part of the METERMUS trial (clinicaltrials.gov NCT03027479). Adipose tissue specimens from four abdominal locations (superficial and deep subcutaneous, visceral (pericolic), and omental) were collected during surgery or exploratory laparoscopy. A fatty acid profile of adipose tissue triglycerides was established by gas chromatography. Fatty acids composition was compared among the four locations using nonparametric Friedman's ANOVA test for repeated measures. Median follow-up of EOC patients was 15 months and patients' RFS was analyzed using Kaplan−Meier survival curves and log-rank test by separating patients into two groups according to median fatty acid levels. The content of long-chain saturated fatty acids (SFAs) was increased and that of long-chain polyunsaturated fatty acids (PUFAs) decreased in deep versus superficial subcutaneous adipose tissue in EOC patients. Nevertheless, the content of total SFAs was ~28%, monounsaturated fatty acids (MUFAs) ~55%, PUFAs n-6 ~11.5%, and PUFAs n-3 about 1.3%, whatever the adipose tissue. When EOC patients were separated into two groups by median fatty acid content, total PUFAs (n-6+n-3) levels, whatever the adipose tissue, were positively and independently associated with RFS. RFS was about two times longer in EOC patients with high versus low total PUFA content (median survival: 12 vs. 27 months, p = 0.01 to <0.0001 according to the tissue). Content of total PUFAs (n-6+n-3) in abdominal adipose tissue (visceral and subcutaneous) are new prognostic factors in EOC.

INTRODUCTION: We aimed to describe management and survival of patients with endometrial cancer (EC) ≥80 years to identify poor prognosis criteria. METHODS: We collected clinical, histologic, surgical and follow-up data for patients with EC ≥ 80 years included in a multicenter French cohort (FRANCOGYN) who underwent primary surgical treatment from 1999 to 2019. The outcomes were overall survival (OS) and disease-free survival (DFS). We performed a descriptive analysis then a survival time analysis and comparison using the Kaplan Meier method and log-rank test. RESULTS: Of the 1647 patients with EC who received treatment during the study period, 184 (11.17%) were ≥80 years. The mean age was 84 years (±3.34). Thirty-three patients (25.4%) died during the follow-up period and 26 relapsed (18.4%). Forty-nine patients were lost to follow-up (27.37%). The median follow-up time was 15.3 months (4.9-28.8). The median OS and DFS was 16.4 months (6.3-24.9) and 13.6 months (4.5-26.6), respectively. Eighty-three patients received adjuvant therapy (45.11%), out of 95 who had a formal or relative indication. Four patients received adjuvant chemotherapy (2.6%), out of 61 who had a formal or relative indication. Inappropriate or underuse of chemotherapy was significantly associated with a lower median OS of 12.6 months [3.73-24] versus 17.3 months [7.93-41.77] when performed appropriately (HR = 4.14, CI 95% [1.62-10.56]), and a lower median DFS of 10.83 months [3.73-24] versus 17.3 months [7.93-28.5] (HR = 9.04, CI 95% [2.04-40.12]). CONCLUSION: Our results suggest that very elderly patients with EC should receive adjuvant chemotherapy according to the standard care guidelines.

Objective: The aim of the present study was to evaluate evolution and prognosis of mucinous ovarian carcinomas (mOC), with respect to the two invasive patterns: expansile and infiltrative invasion. Methods: This was a descriptive, retrospective, multicenter study conducted in 13 French centres from 1 January 2001 to 31 December 2019. All patients operated on for epithelial ovarian neoplasia of the mucinous type (infiltrative/expansile) were included, whether the surgery was performed immediately or after neoadjuvant chemotherapy. Results: A total of 94 women with mucinous carcinomas were included in the present study. Mucinous tumours were divided into 35 expansile (37%) and 59 infiltrative (63%) mOC. There was a statistically significant difference in early and late stages at initial diagnosis between expansile and infiltrative mOC. None of the expansile mOC showed metastatic lymph nodes, whereas almost a quarter of the infiltrative mOC were metastatic to the pelvic/para-aortic region. There was a clear difference in RFS, in favour of expansile mOC, with 90% survival at 5 years, compared with 60% for infiltrative mOC. Conclusions: Although infiltrative and expansile mOC belong to the same histological family, they present many distinctions in clinical presentation, histological invasion, and disease course.
RESUMO
OBJECTIVES: We performed a systematic review in order to describe the clinical presentation, therapeutic management and outcomes of malignant myoepitelioma of the breast. SEARCH STRATEGY: A systematic search of MEDLINE and EMBASE references from January 1980 to Marsh 2020 was performed. We included articles that reported cases of malignant breast myoepithelioma. Data from eligible studies were independently extracted onto standardized forms by two reviewers. RESULTS: 31 articles including 47 cases of malignant breast myoepithelioma and 3 other unpublished cases managed in our establishment were included in this systematic review. The average age at diagnosis was 60.7 years old [range 30-81]. The average size of the tumor was 46mm [range 10 -230]. 30 patients had a partial mastectomy and 18 a total mastectomy. Only 15% of patient (7/48) had an axillary sentinel lymph node biopsy of whom one was positive. 33% of patients (16/48) had an axillary lymph node dissection which was positive for one patient. 19% (n=9) had adjuvant radiotherapy and 15% (n=7) had adjuvant chemotherapy. 33% (n=10) of patients with partial mastectomy had at least one recurrence, versus 5.5% (n=1) after a total mastectomy. The average time between the diagnosis and the first recurrence was 25.4 months [range: 1-50]. 64% (n=7) had a second partial mastectomy and only 18% (n=2) had a total mastectomy. 27% of patient had chemotherapy after their first recurrence and 27% had radiotherapy if it was not received in first line treatment. 40% (n=4/10) of patients with partial mastectomy who recurred have had at least 2 breast recurrences. 28% (n=14) of all patients had distant metastases. 20% of patients (n=10) died whose 80% (n=8) had distant metastatic disease. CONCLUSIONS: This systematic review provided a precise summary of the clinical characteristics and treatment of patients presenting with Malignant breast myoepithelioma in the past 40 years. We anticipate that these results will help inform current investigations and treatment.

INTRODUCTION: Borderline ovarian tumours (BOT) represent 10-20% of epithelial tumours of the ovary. Although their prognosis is excellent, the recurrence rate can be as high as 30%, and recurrence in the infiltrative form accounts for 3% to 5% of recurrences. Affecting, in one third of cases, women of childbearing age, the surgical strategy with ovarian conservation is now recommended despite a significant risk of recurrence. Few studies have focused exclusively on patients who have received ovarian conservative treatment in an attempt to identify factors predictive of recurrence and the impact on fertility. The objective of this study was to identify the risk factors for recurrence of BOT after conservative treatment and the impact on fertility. MATERIAL AND METHODS: This was a retrospective, multicentre study of women who received conservative surgery for BOT between February 1997 and September 2020. We divided the patients into two groups, the "R group" with recurrence and the "NR group" without recurrence. RESULTS: Of 175 patients included, 35 had a recurrence (R group, 20%) and 140 had no recurrence (NR group, 80%). With a mean follow-up of 30 months (IQ 8-62.5), the overall recurrence rate was 20%. Recurrence was BOT in 17.7% (31/175) and invasive in 2.3% (4/175). The mean time to recurrence was 29.5 months (IQ 16.5-52.5). Initial complete peritoneal staging (ICPS) was performed in 42.5% of patients (n = 75). In multivariate analysis, age at diagnosis, nulliparity, advanced FIGO stage, the presence of peritoneal implants, and the presence of a micropapillary component for serous tumours were factors influencing the occurrence of recurrence. The post-surgery fertility rate was 67%. CONCLUSION: This multicentre study is to date one of the largest studies analysing the risk factors for recurrence of BOT after conservative surgery. Five risk factors were found: age at diagnosis, nulliparity, advanced FIGO stage, the presence of implants, and a micropapillary component. Only 25% of the patients with recurrence underwent ICPS. These results reinforce the interest of initial peritoneal staging to avoid ignoring an advanced tumour stage.
