The Influence of Surgical Complexity and Center Experience on Postoperative Morbidity After Minimally Invasive Surgery in Gynecologic Oncology: Lessons Learned from the ROBOGYN-1004 Trial.

BACKGROUND: This study was a secondary analysis of the ROBOGYN-1004 trial conducted between 2010 and 2015. The study aimed to identify factors that affect postoperative morbidity after either robot-assisted laparoscopy (RL) or conventional laparoscopy (CL) in gynecologic oncology. METHODS: The study used two-level logistic regression analyses to evaluate the prognostic and predictive value of patient, surgery, and center characteristics in predicting severe postoperative morbidity 6 months after surgery. RESULTS: This analysis included 368 patients. Severe morbidity occurred in 49 (28 %) of 176 patients who underwent RL versus 41 (21 %) of 192 patients who underwent CL (p = 0.15). In the multivariate analysis, after adjustment for the treatment group (RL vs CL), the risk of severe morbidity increased significantly for patients who had poorer performance status, with an odds ratio (OR) of 1.62 for the 1-point difference in the WHO performance score (95 % CI 1.06-2.47; p = 0.027) and according to the type of surgery (p < 0.001). A focus on complex surgical acts showed significant more morbidity in the RL group than in the CL group at the less experienced centers (OR, 3.31; 95 % CI 1.0-11; p = 0.05) compared with no impact at the experienced centers (OR, 0.87; 95 % CI 0.38-1.99; p = 0.75). CONCLUSION: The findings suggest that the center's experience may have an impact on the risk of morbidity for patients undergoing complex robot-assisted surgical procedures.

Improved Metastatic-Free Survival after Systematic Re-Excision Following Complete Macroscopic Unplanned Excision of Limb or Trunk Soft Tissue Sarcoma.

BACKGROUND: Whether re-excision (RE) of a soft tissue sarcoma (STS) of limb or trunk should be systematized as adjuvant care and if it would improve metastatic free survival (MFS) are still debated. The impact of resection margins after unplanned macroscopically complete excision (UE) performed out of a NETSARC reference center or after second resection was further investigated. METHODS: This large nationwide series used data from patients having experienced UE outside of a reference center from 2010 to 2019, collected in a French nationwide exhaustive prospective cohort NETSARC. Patient characteristics and survival distributions in patients reexcised (RE) or not (No-RE) are reported. Multivariate Cox proportional hazard model was conducted to adjust for classical prognosis factors. Subgroup analysis were performed to identify which patients may benefit from RE. RESULTS: Out of 2371 patients with UE for STS performed outside NETSARC reference centers, 1692 patients were not reviewed by multidisciplinary board before treatment decision and had a second operation documented. Among them, 913 patients experienced re-excision, and 779 were not re-excised. Characteristics were significantly different regarding patient age, tumor site, size, depth, grade and histotype in patients re-excised (RE) or not (No-RE). In univariate analysis, final R0 margins are associated with a better MFS, patients with R1 margins documented at first surgery had a better MFS as compared to patients with first R0 resection. The study identified RE as an independent favorable factor for MFS (HR 0.7, 95% CI 0.53-0.93; p = 0.013). All subgroups except older patients (>70 years) and patients with large tumors (>10 cm) had superior MFS with RE. CONCLUSIONS: RE might be considered in patients with STS of limb or trunk, with UE with macroscopic complete resection performed out of a reference center, and also in originally defined R0 margin resections, to improve LRFS and MFS. Systematic RE should not be advocated for patients older than 70 years, or with tumors greater than 10 cm.

Cell density and extracellular matrix composition mitigate bacterial biofilm sensitivity to UV-C LED irradiation.

Ultraviolet-C light-emitting diodes (UV-C LEDs) are an emerging technology for decontamination applications in different sectors. In this study, the inactivation of bacterial biofilms was investigated by applying an UV-C LED emitting at 280 nm and by measuring both the influence of the initial cell density (load) and presence of an extracellular matrix (biofilm). Two bacterial strains exposing diverging matrix structures and biochemical compositions were used: Pseudomonas aeruginosa and Leuconostoc citreum. UV-C LED irradiation was applied at three UV doses (171 to 684 mJ/cm2) on both surface-spread cells and on 24-h biofilms and under controlled cell loads, and bacterial survival was determined. All surface-spread bacteria, between 105 and 109 CFU/cm2, and biofilms at 108 CFU/cm2 showed that bacterial response to irradiation was dose-dependent. The treatment efficacy decreased significantly for L. citreum surface-spread cells when the initial cell load was high, while no load effect was observed for P. aeruginosa. Inactivation was also reduced when bacteria were grown under a biofilm form, especially for P. aeruginosa: a protective effect could be attributed to abundant extracellular DNA and proteins in the matrix of P. aeruginosa biofilms, as revealed by Confocal Laser Scanning Microscopy observations. This study showed that initial cell load and exopolymeric substances are major factors influencing UV-C LED antibiofilm treatment efficacy. KEY POINTS: • Bacterial cell load (CFU/cm2) could impact UV-C LED irradiation efficiency • Characteristics of the biofilm matrix have a paramount importance on inactivation • The dose to be applied can be predicted based on biofilm properties.

[Development of an artificial intelligence system to improve cancer clinical trial eligibility screening]. / Développement d'une solution d'intelligence artificielle pour améliorer le screening en recherche clinique.

INTRODUCTION: The recruitment step of all clinical trials is time consuming, harsh and generate extra costs. Artificial intelligence tools could improve recruitment in order to shorten inclusion phase. The objective was to assess the performance of an artificial intelligence driven tool (text mining, machine learning, classification…) for the screening and detection of patients, potentially eligible for recruitment in one of the clinical trials open at the "Institut de Cancérologie de Lorraine". METHODS: Computerized clinical data during the first medical consultation among patients managed in an anticancer center over the 2019-2023 period were used to study the performances of an artificial intelligence tool (SAS® Viya). Recall, precision and F1-score were used to determine the artificial intelligence algorithm effectiveness. Time saved on screening was determined by the difference between the time taken using the artificial intelligence-assisted method and that taken using the standard method in clinical trial participant screening. RESULTS: Out of 9876 patients included in the study, the artificial intelligence algorithm obtained the following scores: precision of 96 %, recall of 94 % and a 0.95 F1-score to detect patients with breast cancer (n=2039) and potentially eligible for inclusion in a clinical trial. The screening of 258 potentially eligible patient's files took 20s per file vs. 5min and 6s with standard method. DISCUSSION: This study suggests that artificial intelligence could yield sizable improvements over standard practices in several aspects of the patient screening process, as well as in approaches to feasibility, site selection, and trial selection.

Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy to Treat Pseudomyxoma Peritonei of Ovarian Origin: A Retrospective French RENAPE Group Study.

BACKGROUND: Ovarian pseudomyxoma peritonei (OPMP) are rare, without well-defined therapeutic guidelines. We aimed to evaluate cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) to treat OPMP. METHODS: Patients from the French National Network for Rare Peritoneal Tumors (RENAPE) database with proven OPMP treated by CRS/HIPEC and with histologically normal appendix and digestive endoscopy were retrospectively included. Clinical and follow-up data were collected. Histopathological and immunohistochemical features were reviewed. RESULTS: Fifteen patients with a median age of 56 years were included. The median Peritoneal Cancer Index was 16. Following CRS, the completeness of cytoreduction (CC) score was CC-0 for 9/15 (60%) patients, CC-1 for 5/15 (33.3%) patients, and CC-2 for 1/15 (6.7%) patients. The median tumor size was 22.5 cm. After pathological review and immunohistochemical studies, tumors were classified as Group 1 (mucinous ovarian epithelial neoplasms) in 3/15 (20%) patients; Group 2 (mucinous neoplasm in ovarian teratoma) in 4/15 (26.7%) patients; Group 3 (mucinous neoplasm probably arising in ovarian teratoma) in 5/15 (33.3%) patients; and Group 4 (non-specific group) in 3/15 (20%) patients. Peritoneal lesions were OPMP pM1a/acellular, pM1b/grade 1 (hypocellular) and pM1b/grade 3 (signet-ring cells) in 13/15 (86.7%), 1/15 (6.7%) and 1/15 (6.7%) patients, respectively. Disease-free survival analysis showed a difference (p = 0.0463) between OPMP with teratoma/likely-teratoma origin (groups 2 and 3; 100% at 1, 5, and 10 years), and other groups (groups 1 and 4; 100%, 66.6%, and 50% at 1, 5, and 10 years, respectively). CONCLUSION: These results suggested that a primary therapeutic strategy using complete CRS/HIPEC for patients with OPMP led to favorable long-term outcomes.

Anastomotic leakage and functional outcomes following total mesorectal excision with delayed and immediate colo-anal anastomosis for rectal cancer: Two single-arm phase II trials.

BACKGROUND: Anastomotic leakage (AL) remains a major cause of morbidity following total mesorectal excision (TME). A diverting ileostomy reduces the risk of AL but impairs quality of life (QoL). Delayed colo-anal anastomosis (DCAA) may be an alternative to immediate colo-anal anastomosis (ICAA) without creation of a diverting ileostomy. STUDY DESIGN: Patients with T3 or N+ rectal tumours were treated with neoadjuvant chemoradiation and TME. To evaluate DCAA or ICAA with diverting ileostomy, a two multicenter single-arm phase II trials was designed. The primary endpoint was the rate of AL requiring a diverting ileostomy up to 30 days postoperatively. Secondary endpoints were 30-day postoperative complications, 1- and 2-year disease-free survival; QoL at baseline, 6 months and anorectal function measured by the low anterior resection syndrome questionnaire and Wexner score at baseline, 6 months and a late assessment at median 8 years following surgery. RESULTS: AL requiring diverting ileostomy occurred in one patient (2.1%; 95% confidence interval (CI) [0; 11.1]) in the DCAA group and in five patients (8.6%; 95%CI [3.2; 21.0]) in the ICAA group. Thirty-day postoperative complications occurred in 13 patients (27.1%) in the DCAA group and in 10 patients (19.2%) in the ICAA group. Short and long-term functional outcomes showed similar patterns. CONCLUSION: These two single-arm phase II trials showed that DCAA has low rates of AL requiring a diverting ileostomy and acceptable long-term functional results. DCAA seems a good choice to restore bowel continuity.

Complete pathological response after chemotherapy or immune checkpoint inhibitors in deficient MMR metastatic colorectal cancer: Results of a retrospective multicenter study.

About 5% of the patients with metastatic colorectal cancers (mCRC) present microsatellite instability (MSI)/deficient mismatch repair system (dMMR). While metastasectomy is known to improve overall and progression-free survival in mCRC, specific results in selected patients with dMMR/MSI mCRC are lacking. Our study aimed to describe metastasectomy results, characterize histological response and evaluate pathological complete response (pCR) rate in patients with dMMR/MSI mCRC. We retrospectively reviewed data from all consecutive patients with dMMR/MSI mCRC who underwent surgical metastasectomy between January 2010 and June 2021 in 17 French centers. Primary outcome was to assess the pCR rate defined by tumor regression grade (TRG) 0. Secondary endpoints included relapse-free survival (RFS) and overall survival (OS), and explored TRG as predictive factor for RFS and OS. Among the 88 patients operated, 109 metastasectomies were performed in 81 patients after neoadjuvant treatment [chemotherapy ± targeted therapy (CTT): 69, 85.2%; immunotherapy (ICI): 12, 14.8%], and pCR was achieved in 13 (16.1%) patients. Among the latter, pCR rate were 10.2% in the patients having received CTT (N = 7) and 50.0% in the patients treated with ICI (N = 6). Radiological response did not predict TRG. With a median follow-up of 57.9 (IQR 34.2-81.6) months, median RFS was 20.2 (15.4-not reached) months, median OS was not reached. Major pathological responses (TRG0 + TRG1) were significantly associated with longer RFS (HR 0.12, 95% CI 0.03-0.55; P = .006). The pCR rate of 16.1% achieved with neoadjuvant treatment in patients with dMMR/MSI mCRC is consistent with previously reported rates in pMMR/MSS mCRC. Immunotherapy showed better pCR rate than chemotherapy ± targeted therapy. Further prospective trials are needed to validate immunotherapy as neoadjuvant treatment in resectable/potentially resectable dMMR/MSI mCRC and identify predictive factors for pCR.

Is Delaying a Coloanal Anastomosis the Ideal Solution for Rectal Surgery?: Analysis of a Multicentric Cohort of 564 Patients From the GRECCAR.

OBJECTIVES: To assess the specific results of delayed coloanal anastomosis (DCAA) in light of its 2 main indications. BACKGROUND: DCAA can be proposed either immediately after a low anterior resection (primary DCAA) or after the failure of a primary pelvic surgery as a salvage procedure (salvage DCAA). METHODS: All patients who underwent DCAA intervention at 30 GRECCAR-affiliated hospitals between 2010 and 2021 were retrospectively included. RESULTS: Five hundred sixty-four patients (male: 63%; median age: 62 years; interquartile range: 53-69) underwent a DCAA: 66% for primary DCAA and 34% for salvage DCAA. Overall morbidity, major morbidity, and mortality were 57%, 30%, and 1.1%, respectively, without any significant differences between primary DCAA and salvage DCAA ( P = 0.933; P = 0.238, and P = 0.410, respectively). Anastomotic leakage was more frequent after salvage DCAA (23%) than after primary DCAA (15%), ( P = 0.016).Fifty-five patients (10%) developed necrosis of the intra-abdominal colon. In multivariate analysis, intra-abdominal colon necrosis was significantly associated with male sex [odds ratio (OR) = 2.67 95% CI: 1.22-6.49; P = 0.020], body mass index >25 (OR = 2.78 95% CI: 1.37-6.00; P = 0.006), and peripheral artery disease (OR = 4.68 95% CI: 1.12-19.1; P = 0.030). The occurrence of this complication was similar between primary DCAA (11%) and salvage DCAA (8%), ( P = 0.289).Preservation of bowel continuity was reached 3 years after DCAA in 74% of the cohort (primary DCAA: 77% vs salvage DCAA: 68%, P = 0.031). Among patients with a DCAA mannered without diverting stoma, 75% (301/403) have never required a stoma at the last follow-up. CONCLUSIONS: DCAA makes it possible to definitively avoid a stoma in 75% of patients when mannered initially without a stoma and to save bowel continuity in 68% of the patients in the setting of failure of primary pelvic surgery.

2022 PSOGI Consensus on HIPEC Regimens for Peritoneal Malignancies: Diffuse Malignant Peritoneal Mesothelioma.

BACKGROUND: Diffuse malignant peritoneal mesothelioma (DMPM) is a rare and aggressive primary peritoneal disease, with recommended treatment, in eligible patients, of a combination of complete cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC). As treatment is multimodal, there is a wide heterogeneity of HIPEC protocols precluding clear comparisons. Standardization at an international level is required. METHODS: The Peritoneal Surface Oncology Group International (PSOGI) designated a steering committee to produce consensus recommendations for HIPEC regimens, adapted to each etiology. The Grades of Recommendation, Assessment, Development, and Evaluation (GRADE) methodology was used, based on a systematic review focused on main outcomes related to HIPEC regimens in DMPM patients and on the patient, intervention, comparator, and outcome (PICO) method to elaborate main questions. An opinion survey was added. Furthermore, a Delphi process was performed with voting from a panel of international experts. RESULTS: Eleven questions were elaborated, including two for future research requirements and three to assess the HIPEC regimen preference of the panel. The level of evidence underlying questions was globally low. Overall, 75 (86%) and 67 (77%) of the 87 invited experts completed the vote at the first and second round, respectively. HIPEC following complete CRS was strongly supported by 88% of voters with no need to plan comparative studies with CRS alone for 61.2% of voters. Bi-drug regimens appeared to be preferred to mono-drug ones and cisplatin was globally favored. The opinion survey confirmed the combination of cisplatin and doxorubicin as the recommended regimen. CONCLUSION: International consensus confirmed the indication of HIPEC following complete CRS in DMPM patients and recommended cisplatin-doxorubicin as the first-line HIPEC regimen.

Peritoneal Mesothelioma: Systematic Review of Hyperthermic Intraperitoneal Chemotherapy (HIPEC) Protocol Outcomes.

Diffuse malignant peritoneal mesothelioma (DMPM) prognosis was improved by the locoregional treatment combining cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC). HIPEC is a multiparametric treatment with multiple protocols proposed and reviewed in this work. A systematic review of medical literature was performed according to PRISMA guidelines. The search strategy used "malignant peritoneal mesothelioma" and "HIPEC" as keywords in three databases. Studies were included if reporting precisely the HIPEC regimen and the related outcomes, if comparing regimen, or if reporting national/international guidelines. The GRADE methodology was used to rate the level of evidence. Twenty-eight studies were included in this review: 1 was a meta-analysis, 18 reported cohort outcomes, 4 retrospectively compared HIPEC regimens, and 5 were guidelines. Six HIPEC regimens were found, 4 with one drug (cisplatin, mitomycine-C, carboplatin, oxaliplatin), 2 using two drugs (cisplatin-doxorubicin or cisplatin-mitomycine-C). Cisplatin, up to 250 mg/m2 over 90 min, appeared as the key HIPEC drug with a toxicity profile well controlled by the concomitant intravenous perfusion of sodium thiosulfate. Comparative studies tended to show that a bi-drug regimen led to better long-term oncologic outcomes, with cisplatin 50 mg/m2 plus doxorubicin 15 mg/m2 being safe and more efficient. This late protocol was the most widely used and recommended in 3 out of 4 international guidelines. Cisplatin was the preferred drug for HIPEC in DMPM patients. Most of the time, it was combined with doxorubicin for 90 min. A harmonization of protocols and further comparative studies are needed to optimize HIPEC regimen choice.

Prognostic factors of local control and progression-free survival in AJCC stages T1 and T2 cervical cancer patients treated with adjuvant brachytherapy after chemoradiotherapy.

Purpose: We assessed prognostic factors of local control and progression-free survival (PFS) of patients treated for AJCC stages T1 and T2 cervical cancer using utero-vaginal brachytherapy after chemoradiotherapy. Material and methods: This retrospective single-institution analysis included patients who underwent brachytherapy after radiochemotherapy between 2005 and 2015 at the Institut de Cancérologie de Lorraine. Adjuvant hysterectomy was optional. A multivariate analysis of prognostic factors was carried out. Results: Of 218 patients, 81 (37.2%) were AJCC stage T1, and 137 (62.8%) were AJCC stage T2. 167 (76.6%) patients had squamous cell carcinoma, 97 (44.5%) patients had pelvic nodal disease, and 30 (13.8%) patients had para-aortic nodal disease. One hundred eighty-four patients (84.4%) underwent concomitant chemotherapy, while adjuvant surgery was performed in 91 patients (41.9%) and 42 (46.2%) patients had pathological complete response. Median follow-up was 4.2 years, and local control was reported in 87.8% (95% CI: 83.0-91.8) and 87.2% (95% CI: 82.3-91.3) of patients at 2 and 5 years, respectively. In multivariate analysis, T stage (hazard ratio [HR] = 3.65, 95% CI: 1.27-10.46, p = 0.016) was associated with local control. PFS was reported in 67.6% (95% CI: 60.9-73.4) and 57.4% (95% CI: 49.3-64.2) of patients at 2 and 5 years, respectively. In multivariate analysis, para-aortic nodal disease (HR = 2.03, 95% CI: 1.16-3.54, p = 0.012), pathological complete response (HR = 0.33, 95% CI: 0.15-0.73, p = 0.006), and intermediate-risk clinical tumor volume of > 60 cc (HR = 1.90, 95% CI: 1.22-2.98, p = 0.005) were associated with PFS. Conclusions: Lower dose brachytherapy may benefit AJCC stages T1 and T2 tumors, whereas higher doses are required for larger tumors and para-aortic nodal disease involvement, respectively. Pathological complete response should be associated with better local control and not surgery.

Transcriptomic Study on Human Skin Samples: Identification of Two Subclasses of Actinic Keratoses.

Actinic keratoses (AKs) are sun-damaged skin areas that affect 20% of the European adult population and more than 50% of people aged 70 years and over. There are currently no clinical or histological features allowing us to identify to which clinical class (i.e., regression or progression) an AK belongs. A transcriptomic approach seems to be a robust tool for AK characterization, but there is a need for additional studies, including more patients and elucidating the molecular signature of an AK. In this context, the present study, including the largest number of patients to date, is the first aiming at identifying biological features to objectively distinguish different AK signatures. We highlight two distinct molecular profiles: AKs featuring a molecular profile similar to squamous cell carcinomas (SCCs), which are called "lesional AKs" (AK_Ls), and AKs featuring a molecular profile similar to normal skin tissue, which are called "non-lesional AKs" (AK_NLs). The molecular profiles of both AK subclasses were studied, and 316 differentially expressed genes (DEGs) were identified between the two classes. The 103 upregulated genes in AK_L were related to the inflammatory response. Interestingly, downregulated genes were associated with keratinization. Finally, based on a connectivity map approach, our data highlight that the VEGF pathway could be a promising therapeutic target for high-risk lesions.

Role of Hyperthermic Intraperitoneal Chemotherapy Combined with Cytoreductive Surgery as Consolidation Therapy for Advanced Epithelial Ovarian Cancer.

BACKGROUND: Patients with advanced epithelial ovarian cancer who undergo incomplete surgery followed by six cycles of chemotherapy could benefit from second-look or consolidation cytoreductive surgery (CCRS). The primary goal of this study was to evaluate the overall survival (OS) in patients undergoing complete CCRS and the factors affecting survival. The secondary goal was to study the benefit of hyperthermic intraperitoneal chemotherapy (HIPEC) in these patients. METHODS: This was a retrospective analysis of 173 patients with CCRS with (n = 118) or without (n = 55) HIPEC treated at 12 French centers. Only patients having a completeness of cytoreduction (CC) 0/1 resection and a minimum of 5 years of follow-up were included. HIPEC was performed systematically for all patients except those treated at the four centers that did not perform HIPEC. RESULTS: The median Peritoneal Cancer Index was 6 (range 0-33). Closed HIPEC was performed in 59 (34.1%) patients and open HIPEC was performed in 56 (32.3%) patients. Grade 3-4 complications occurred in 64 (36.9%) patients. The median OS was 35.67 months (95% confidence interval [CI] 29.8-46.1) and was significantly longer for CCRS + HIPEC (31.4 months without HIPEC and 42.5 months with HIPEC; p = 0.022). On multivariate analysis, closed HIPEC (hazard ratio [HR] 0.46, 95% CI 0.29-0.73; p < 0.001) resulted in a longer OS, and age > 65 years (HR 2.17, 95% CI 1.14-4.11; p = 0.018) and bowel resection (HR 1.98, 95% CI 1.27-3.08; p = 0.020) led to a shorter OS. On multivariate logistic regression analysis, closed HIPEC (odds ratio 0.18; p = 0.001) was associated with a lower risk of dying at 5 years. CONCLUSIONS: CCRS was performed with an acceptable morbidity and resulted in good overall survival. The role of HIPEC in addition to CCRS should be evaluated in prospective, randomized studies and the closed technique prospectively compared with the open technique.

Efficacy of chemotherapy according to BRCA status in patients with high-grade serous ovarian carcinoma at first platinum-sensitive relapse.

OBJECTIVE: Chemotherapy for high-grade serous ovarian cancers in platinum-sensitive relapse includes carboplatin/paclitaxel, carboplatin/gemcitabine, and carboplatin/pegylated liposomal doxorubicin. According to in vitro data, BRCA mutated patients are sensitive to replicative stress agents but BRCA status is not yet used for the choice of chemotherapy at relapse. Our aim was to assess these doublets according to BRCA status in first platinum-sensitive relapse. METHODS: The ESME ovarian cancer database comprises a multicenter retrospective cohort of patients with ovarian cancer treated in French cancer centers between January 2011 and December 2017. Patients with high-grade serous ovarian cancers at first platinum-sensitive relapse who received one of these doublets were included. The objective was to compare progression-free survival of each chemotherapy doublet according to BRCA status. RESULTS: Among the 10 263 patients in the database, 1539 patients had a first platinum-sensitive relapse: 825 BRCA wild type patients (53.6%) and 304 BRCA mutated patients (19.8%) (7 patients had a homologous recombination mutation and BRCA status was unkown for 403 patients). Median progression-free survival was longer in BRCA mutated patients than in BRCA wild type patients when receiving carboplatin/pegylated liposomal doxorubicin without maintenance treatment (15.8 vs 11.8 months; p<0.001). In contrast, we observed no difference in patients treated with carboplatin/paclitaxel (14.6 vs 14.3 months, respectively; p=0.70) or in those treated with carboplatin/gemcitabine (12.0 vs 9.8 months, respectively; p=0.18). In BRCA wild type patients without maintenance, better progression-free survival occurred with carboplatin/paclitaxel (median progression-free survival 14.3 months) than with carboplatin/gemcitabine and carboplatin/pegylated liposomal doxorubicin (9.8 and 11.8 months, respectively; p=0.017). In BRCA mutated patients without maintenance, there was no difference between the three doublets (median progression-free survival of 14.6, 12.0, and 15.8 months with carboplatin/paclitaxel, carboplatin/gemcitabine, and carboplatin/pegylated liposomal doxorubicin, respectively; p=0.40). CONCLUSION: While treatment with carboplatin/paclitaxel, carboplatin/gemcitabine, and carboplatin/pegylated liposomal doxorubicin shows comparable efficacy in BRCA mutated patients, treatment with carboplatin/paclitaxel appears to be more effective than carboplatin/gemcitabine and carboplatin/pegylated liposomal doxorubicin in BRCA wild type patients with high-grade serous ovarian cancers at first platinum-sensitive relapse.

[Fat embolism in common carotid artery following temporal autologous fat graft]. / Embolie graisseuse carotidienne dans les suites d'un lipofilling temporal.

Lipofilling is a well-known procedure, initially described by Coleman in 1991. Many cases of fat embolism following this procedure are published. Our patient had a common carotid fat embolism after a temporal autologous fat graft.
