Sclerosing Epithelioid Fibrosarcoma (SEF) versus Low Grade Fibromyxoid Sarcoma (LGFMS): Presentation and outcome in the nationwide NETSARC+ series of 330 patients over 13 years.

Sclerosing Epithelioid Fibrosarcoma (SEF) and Low Grade Fibromyxoid Sarcoma (LGFMS) are ultrarare sarcomas sharing common translocations whose natural history are not well known. We report on the nationwide exhaustive series of 330 patients with SEF or LGFMS in NETSARC+ since 2010. PATIENTS AND METHODS: NETSARC (netsarc.org) is a network of 26 reference sarcoma centers with specialized multidisciplinary tumor boards (MDTB). Since 2010, (i) pathological review has been mandatory for sarcoma,and (ii) tumour/patients' characteristics have been collected in the NETSARC+ nationwide database. The characteristics of patients with SEF and LGFMS and their outcome are compared. RESULTS: 35/73 (48%) and 125/257(49%) of patients with SEF and LGFMS were female. More visceral, bone and trunk primary sites were observed in SEF (p < 0.001). 30% of SEF vs 4% of LGFMS patients had metastasis at diagnosis (p < 0.0001). Median size of the primary tumor was 51 mm (range 10-90) for LGFMS vs 80 (20-320) for SEF (p < 0.001). Median age for LGFMS patients was 12 years younger than that of SEF patients (43 [range 4-98] vs 55 [range 10-91], p < 0.001). Neoadjuvant treatment was more often given to SEF (16% vs 9%, p = 0.05). More patients with LGFMS were operated first in reference centers (51% vs 26%, p < 0.001). The R0 rate on the operative specimen was 41% in LGFMS vs 16% in SEF (p < 0.001). Median event-free survival (EFS) of patients with SEF and LGFMS were 32 vs 136 months (p < 0.0001). The median overall survival (OS) was not reached. Fifty-months OS was 93% vs 81% for LGFMS vs SEF (p = 0.05). Median OS was 77 months after first relapse, similar for SEF and LGFMS. In multivariate analysis, age, tumor size, metastasis at diagnosis were independent prognostic factors for OS in LGFMS. CONCLUSIONS: Although sharing close molecular alterations, SEF and LGFMS have a different natural history, clinical presentation and outcome, with a higher risk of metastatic relapse in SEF. Survival after relapse is longer than with other sarcomas, and similar for SEF and LGFMS.

Intraoperative motive for incomplete resection in primary retroperitoneal sarcoma.

INTRODUCTION: Surgical resection is the current standard of care for retroperitoneal sarcoma (RPS). Recent data suggests that up to 5% of patient have incomplete (R2) resection. The exact reason why patients scheduled for surgery with a curative intent to treat ended up with an R2 resection is largely unknown. AIM OF THE STUDY: To identify intraoperative findings responsible for incomplete (R2) resection in primary RPS. METHODS: All records of consecutive patients scheduled for a non-metastatic primary RPS surgery between 1995 and 2020 in a tertiary care sarcoma centre were retrospective analyzed. RESULTS: Among the 347 patients scheduled for surgery, 13 (3.7%) had an incomplete (R2) resection. The reasons for incomplete surgery were intraoperative finding of vascular involvement of great vessels in 5 patients, previously undetected peritoneal metastases in 5 patients, invasion of contralateral kidney/ureter in 2 patients and the need to preserve both kidneys in 1 patient because of his past medical history. Among these patients, 3 had a laparotomy without resection and 10 had a partial resection (i.e. debulking surgery). Severe postoperative complications occurred in 5 patients. The median length of stay in hospital was 19days. After a median follow-up of 12months, the median survival of patients after incomplete resection was 18months. The 1-y, 5-y and 8-y overall survival (OS) for these patients were 46%, 14%, and 7%, respectively. CONCLUSION: Incomplete (R2) resection for a primary RPS surgery is rare in specialized sarcoma center. The next steps should be to identify the preoperative criteria that lead to this accurate selection and to define the best practice in front of a peroperative discovery of an unresectable RPS. LEVEL OF EVIDENCE: III.

Natural history and treatment efficacy in an ambispective case series of NTRK-rearranged mesenchymal tumors.

BACKGROUND: Apart for infantile fibrosarcoma (IFS), very little is known about NTRK-rearranged mesenchymal tumors (NMTs). The objective of this study is to describe the distribution, characteristics, natural history, and prognosis of NMT. PATIENTS AND METHODS: This study was carried out as a translational research program, retrospectively from a cohort of 500 soft tissue sarcoma (STS; excluding IFS) and prospectively both in routine practice and from the RNASARC molecular screening program (N = 188; NCT03375437). RESULTS: Using RNA-sequencing, NTRK fusion was detected in 16 patient tumors diagnosed as STS: 8 samples of sarcoma with simple genomics (4 NTRK-rearranged spindle cell neoplasm, 3 ALK/ROS wild-type inflammatory myofibroblastic tumor, and 1 quadruple Wild-type gastrointestinal stromal tumor) and 8 samples of sarcomas with complex genomics (dedifferentiated liposarcoma, intimal sarcoma, leiomyosarcoma, undifferentiated pleomorphic sarcoma, high-grade uterine sarcoma, malignant peripheral nerve sheath tumor). Among the eight patients with simple genomics, four were treated with tyrosine receptor kinase inhibitor (TRKi) at different stages of the disease and all benefited from the treatment, including one complete response. Among the eight other patients, six evolved with metastatic spreading and the median metastatic survival was 21.9 months, as classically reported in these tumor types. Two of them received a first-generation TRKi without objective response. CONCLUSIONS: Our study confirms low frequency and histotype diversity of NTRK fusion in STS. While the activity of TRKi in simple genomics NMT is confirmed, our clinical data encourage subsequent studies focusing on the biological relevance of NTRK fusions in sarcomas with complex genomics together with the efficacy of TRKi in this population.

[Screening and healthcare for pregnant women with psycho-social vulnerability : A French national study]. / Dépistage et parcours de soins en cas de vulnérabilités psycho-sociales maternelles : une enquête nationale française.

INTRODUCTION: Psycho-social vulnerabilities are a medical risk factor for both fetus and mother. Association between socioeconomic status and prenatal follow-up has been well established and inadequate follow-up is associated with higher morbidity and mortality in women in unfavorable situations. OBJECTIVE: The objective is to identify screening strategies and to describe existing systems for pregnant women in psycho-social vulnerability in French maternity hospitals. MATERIAL AND METHODES: This is a national survey conducted by questionnaire in all French maternities. RESULTS: Screening by means of targeted questions is carried out by 96.7% of maternity units. Early prenatal interviews are offered systematically by 64% of maternity units and access to them is still difficult for women in vulnerable situations. In order to organize care pathways, 28.7% of maternities have a structured unit within their establishment and 81% state that they have mobilizable caregivers. Multidisciplinary meetings for the coordination of the various stakeholders are held by 85.8% of maternity units. Collaboration with networks and associations is emphasized. CONCLUSION: A large proportion of maternities seek to identify women in situation of psycho-social vulnerabilities and to organize care paths. However, the resources implemented still appear insufficient for many maternity units. Each maternity hospital has resources and is developing initiatives to deal with the difficulties of care.

Diagnostic value of frozen section examination of sentinel lymph nodes in early-stage cervical cancer at the time of ultrastaging.

OBJECTIVES: We aimed to assess the diagnostic value of frozen-section pathologic examination (FSE) of sentinel lymph nodes (SLN) in patients with early-stage cervical cancer. METHODS: Two French prospective multicentric database on SLN biopsy for cervical cancer (SENTICOL I and II) were analysed. Patients with IA to IIA1 2018 FIGO stage, who underwent SLN biopsy with both FSE and ultrastaging examination were included. RESULTS AND DISCUSSION: Between 2005 and 2012, 313 patients from 25 centers fulfilled the inclusion criteria. Metastatic involvement of SLN was diagnosed in 52 patients (16.6%). Macrometastases, micrometastases and isolated tumor cells (ITCs) were found in 27, 12 and 13 patients respectively. Among the 928 SLNs analysed, FSE identified 23 SLNs with macrometastases in 20 patients and 5 SLNs with micrometastases in 2 patients whereas no ITCs were identified. Ultrastaging of negative SLNs by FSE found macrometastases, micrometastases and ITCs in additional 7, 11 and 17 SLNs. Ultrastaging increased significantly the rate of patients with positive SLN from 7% to 16.6% (p < 0.0001). The sensitivity and the negative predictive value of FSE were 42.3% and 89.7% respectively or 56.4% and 94.1% if ITCs were excluded. False-negative cases were more frequent with tumor size ≥ 20 mm (OR = 4.46, 95%IC = [1.45-13.66], p = 0.01) and preoperative brachytherapy (OR = 4.47, 95%IC = [1.37-14.63], p = 0.01) and less frequent with patients included in higher volume center (>5 patients/year) (OR = 0.09, 95%IC = [0.02-0.51], p = 0.01). CONCLUSIONS: FSE of SLN had a low sensitivity for detecting micrometastases and ITCs and a high negative predictive value for SLN status. Clinical impact of false-negative cases has to be assessed by further studies.

Should We Abandon Systematic Pelvic and Paraaortic Lymphadenectomy in Low-Grade Serous Ovarian Cancer?

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.

Risk factors for failure of bilateral sentinel lymph node mapping in early-stage cervical cancer.

BACKGROUND: The objective of this study was to determine clinical, tumoral and surgical factors associated with successful bilateral sentinel lymph node mapping (SBM) in early-stage cervical cancer. METHODS: We performed an ancillary work on the data of two prospective trials on SLN biopsy for FIGO IA-IIA cervical cancer (SENTICOL I & II). Patients having Sentinel lymph node (SLN) mapping for early-stage cervical cancer were included between 2005 and 2012 from 28 French oncologic centers. SLN was detected by a combined labeling technique (blue and isotopic). RESULTS: 405 patients were included for analysis: SLNs were identified on at least one side of the pelvis in 381 patients (94.1%) and bilaterally in 326 patients (80.5%). The mean age was 45.4 years [22-85 years]. Most patients had IB1 pathologic FIGO 2018 stage (81.3%) and squamous cell carcinoma (71%). Surgeries were mainly performed by minimally invasive approach (368 patients - 90.9%). By multivariate analysis, lower SBM rate was significantly associated with Age ≥70 years (ORa = 0.02, 95%CI = [0.001-0.28], p = 0.004), tumor size larger than 20 mm (ORa = 0.46,95%CI = [0.21-0.99], p = 0.048) and Body-mass index higher than 30 kg/m2 (ORa = 0.28, 95%CI = [0.12-0.65], p = 0.003). SBM rate was significantly higher in high skills centers (>5patients/year) (ORa = 8.05, 95%CI = [2.06-31.50], p = 0.003) and in SENTICOL II (2009-2012) compared to SENTICOL I (2005-2007) (ORa = 2.6, 95%CI = [1.23-5.51], p = 0.01). CONCLUSIONS: In early-stage cervical cancer, bilateral SLN detection rates is lower in patients aged more than 70years, patients with BMI≥30 kg/m2 and larger tumor ≥20 mm whereas stronger experience of SLN biopsy technique improves bilateral SLN detection.

Emergency attendances and hospitalisations for complications after transrectal ultrasound-guided prostate biopsies: a five-year retrospective multicentre study.

INTRODUCTION: Transrectal ultrasound-guided (TRUS) prostate biopsy is an established procedure for diagnosis of prostate cancer. Complications after TRUS biopsy are not well reported in Hong Kong. This study evaluated the 5-year incidences of TRUS biopsy complications and potential risk factors for those complications. METHODS: This was a retrospective review of biopsies performed from 2013 to 2017 in two local hospitals, using data retrieved from electronic medical records. The primary outcome was the occurrence of complications requiring either emergency attendances or hospitalisations within 30 days after biopsy. Potential risk factors were examined using multiple logistic regression analysis. RESULTS: In total, 1699 men were included (mean age ± standard deviation: 67 ± 7 years; median prostate-specific antigen level: 7.9 µg/L [interquartile range, 5.5-12.6 µg/L]); 4.3% had pre-biopsy bacteriuria. Overall, 5.7% and 3.8% of post-biopsy complications required emergency attendances and hospitalisations, respectively. Gross haematuria and rectal bleeding requiring emergency attendances developed in 2.1% and 0.4% of men; 0.8% and 0.4% required hospitalisations. Furthermore, 1.5% of men developed acute urinary retention requiring hospitalisations; 1.9% and 1.2% had post-biopsy infections requiring emergency attendances and hospitalisations, respectively, and 0.9% had urosepsis requiring hospitalisations. Prostate volume >48 cc was associated with an increased risk of post-biopsy retention (odds ratio 2.75, 95% confidence interval: 1.23-4.17). CONCLUSIONS: The rate of overall complications after TRUS biopsy was low. The most common complications requiring emergency attendances and hospitalisations were gross haematuria and acute urinary retention, respectively. Prostate volume >48 cc increased the risk of post-biopsy urinary retention.

[Prophylactic hysterectomy in Lynch syndrome: Feasibility and outcomes]. / Faisabilité et résultats de l'hystérectomie prophylactique dans le syndrome de Lynch.

OBJECTIVES: Lynch syndrome (LS) is a hereditary predisposition to cancers, first of all, colo-rectal and endometrial cancers in women. Although recommended, gynecologic screening has never proven its benefit. Prophylactic surgery can be considered once the parental project is completed. There are few data regarding the assessment of prophylactic surgery. The objectives of our study were to evaluate the feasibility and morbidity of prophylactic hysterectomy in patients with Lynch syndrome. METHODS: This is a descriptive retrospective study of consecutive patients with LS undergoing prophylactic hysterectomy at the Georges-Pompidou European Hospital from 2002 to 2016. We collected demographic characteristics, results of preoperative assessment, intra- and postoperative data, final pathologic result as well as postoperative follow-up data. RESULTS: Forty patients were included in the study, and seventeen women had a history of colon cancer surgery. All hysterectomies were performed by laparoscopy, with two cases of laparoconversion. Two intraoperative complications occurred: serosal small bowel injuries and superficial bladder injury. Two early postoperative complications occurred (a peritonitis on small bowel perforation and a peritonitis on left ureteral injury) and two late complications (vesico-vaginal fistula and adhesive small bowel obstruction). All operative specimens were benign. With a median follow-up of 28 months [5-52], no patient had peritoneal cancer. CONCLUSIONS: Our study shows that prophylactic hysterectomy in Lynch syndrome should be done with caution. Per and postoperative complication rates appear to be higher than in general population, probably related to a more frequent history of colorectal cancer. However, total hysterectomy with bilateral salpingo-oophorectomy appears to be an effective strategy for preventing gynecological cancers in women with the Lynch syndrome.

Predictive factors of unexpected lymphatic drainage pathways in early-stage cervical cancer.

OBJECTIVES: The purpose of this study was to describe sentinel lymph nodes (SLN) topography in patients with early-stage cervical cancer and to determine factors associated with atypical lymphatic drainage pathway (LDP). METHODS: We analyzed the data of two prospective multicentric trials on SLN biopsy for cervical cancer (SENTICOL I and II) in women undergoing surgery for early-stage cervical cancer. SLN detection was realized with a combined labeling technique (Patent blue and radioactive tracer). Patients having bilateral SLN detection were included. Univariate and Multivariate analysis were performed by patients and by side to assess clinical and pathologic factors that may predict atypical LDP. RESULTS: Between January 2005 and July 2012, 326 patients with 1104 intraoperative detected SLNs fulfilled the inclusion criteria. The SLNs were mainly located in the interiliac or external iliac area in 83.2%. The other localizations were: 9.2% in the common iliac area, 3.9% in the parametrium, 1.6% in the promontory area, 1.5% in the paraaortic area and 0.5% in other areas. Thirty-five patients (10.7%) had atypical SLN without SLN in typical area on one or both sides. In multivariate analysis, tumor size ≥20 mm appeared as an independent factor of having at least one exclusive atypical LDP (ORa = 3.95 95%CI = [1.60-9.78], p = 0.003). Multiparity decreased significantly the probability of having at least one exclusive atypical LDP (ORa = 0.16 95%CI = [0.07-0.39], p < 0.0001). CONCLUSIONS: Tumor size larger than 20 mm and nulliparity increase the risk of having exclusive atypical LDP in early-stage cervical cancer.

Predictive factors of severe perioperative morbidity of radical hysterectomy with lymphadenectomy in early-stage cervical cancer: A French prospective multicentric cohort of 248 patients.

OBJECTIVE: The purpose of this study was to assess the postoperative morbidity after radical hysterectomy (RH) for early-stage cervical cancer and to determine risk factors of severe perioperative morbidity. METHODS: Data of two prospective trials on sentinel node biopsy for cervical cancer (SENTICOL I & II) were analysed. Patients having a radical hysterectomy were included between 2005 and 2012 from 25 French oncologic centers. Postoperative complications were prospectively recorded in a pre-specified analysis. RESULTS: 248 patients met the inclusion criteria. The median age was 44.5 years [25-85]. 88.7% of patients had a stage IB1 disease. There were 71.4% epidermoid carcinomas and 25% adenocarcinomas. 125 patients (50.4%) had a laparoscopic-assisted vaginal RH, 88 patients (35.5%) had a total laparoscopic RH, 26 patients (10.5%) had an open RH and 9 patients (3.6%) had a robotic-assisted RH. Sixteen patients (6.4%) had intraoperative complications. On a multivariate analysis, intraoperative complications were significantly associated with BMI >30 kg/m2. The urinary, lymphovascular and neurologic complications rates were respectively 34.3%, 20.6% and 19.8%. 31 patients (12.5%) had severe postoperative complications (Clavien-Dindo ≥ 3 or CTCAE ≥ 3). On multivariate analysis, severe postoperative complications were associated with parametrial involvement, preoperative brachytherapy and inclusion in low surgical skills center. CONCLUSIONS: This study based on prospective data showed that RH has low severe postoperative complications. The main complications were urinary infections and lower limb lymphedema. Patients with early-stage cervical cancer should be referred to expert center to ensure best surgical outcomes.

Steroid-Refractory Autoimmune Myocarditis after Pembrolizumab Therapy: Failure of Equine Anti-Thymocyte Globulin to Prevent Heart Failure.

While immune checkpoint inhibitors (ICIs) are improving outcomes for many cancers, they can have severe adverse effects. Though cardiac immune-related adverse effects (irAEs) are rare, they have considerable morbidity and mortality. Prior case studies have demonstrated successful treatment of ICI induced autoimmune myocarditis with a variety of immunosuppressive regimens. This case describes steroid-refractory autoimmune myocarditis after treatment with pembrolizumab. Treatment with equine anti-thymocyte globulin, a regimen previously documented to reverse ICI induced autoimmune myocarditis, temporarily improved clinical status and cardiac biomarkers, however eventually failed to prevent progression to heart failure and cardiovascular death. This case highlights the importance of early stress-dose steroids, identifies troponin as a potential marker of treatment response, and underscores the value of collaboration between oncology and cardiology for optimal management.

Sentinel lymph node biopsy without axillary lymphadenectomy after neoadjuvant chemotherapy is accurate and safe for selected patients: the GANEA 2 study.

PURPOSE: GANEA2 study was designed to assess accuracy and safety of sentinel lymph node (SLN) after neo-adjuvant chemotherapy (NAC) in breast cancer patients. METHODS: Early breast cancer patients treated with NAC were included. Before NAC, patients with cytologically proven node involvement were allocated into the pN1 group, other patient were allocated into the cN0 group. After NAC, pN1 group patients underwent SLN and axillary lymph node dissection (ALND); cN0 group patients underwent SLN and ALND only in case of mapping failure or SLN involvement. The main endpoint was SLN false negative rate (FNR). Secondary endpoints were predictive factors for remaining positive ALND and survival of patients treated with SLN alone. RESULTS: From 2010 to 2014, 957 patients were included. Among the 419 patients from the cN0 group treated with SLN alone, one axillary relapse occurred during the follow-up. Among pN1 group patients, with successful mapping, 103 had a negative SLN. The FNR was 11.9% (95% CI 7.3-17.9%). Multivariate analysis showed that residual breast tumor size after NAC ≥ 5 mm and lympho-vascular invasion remained independent predictors for involved ALND. For patients with initially involved node, with negative SLN after NAC, no lympho-vascular invasion and a remaining breast tumor size 5 mm, the risk of a positive ALND is 3.7% regardless the number of SLN removed. CONCLUSION: In patients with no initial node involvement, negative SLN after NAC allows to safely avoid an ALND. Residual breast tumor and lympho-vascular invasion after NAC allow identifying patients with initially involved node with a low risk of ALND involvement.

Precaval positive sentinel lymph node with bilateral negative pelvic sentinel lymph node in low-risk endometrial cancer patient.

We here describe a case report of a positive precaval sentinel lymph node with negative pelvic sentinel lymph node in a patient with endometrial cancer. A 45-years-old woman was diagnosed with a grade 2 endometrioid carcinoma of the endometrium. She was treated with a hysterectomy and bilateral salpingo-oophorectomy, associated with dissection of sentinel lymph nodes (SLNs). We detected bilateral external and common bilateral iliac nodes and one precaval node. At pathological examination the pelvic nodes were non-metastatic, but the precaval node was positive. In this patient, sentinel node biopsy improved risk-assessment and adjuvant treatment.

What about sentinel lymph node biopsy for early breast cancer during pregnancy?

Pregnancy-associated breast cancer is rare, but this clinical situation arises in 1/10,000-1/3000 pregnancies. In patients presenting an early-stage breast tumor devoid of clinically pathological lymph node, sentinel lymph node (SLN) biopsy has not yet been validated as a routine procedure for pregnant women due to the lack of data in the literature. The blue dye injection is not recommended because of 2% theoretical risk of anaphylactic shock. Several studies have shown that Tc99m injection at conventional dose between 12.1 and 18.5MBq exposed the fetus to an irradiation between 0.011 and 0.0245mSv much below the 50mSv recommended threshold. As evidenced by lymphoscintigraphy scans, the dose of injected Tc99m is localized at the injection site and in the SLN. According to the literature, the SLN technique does not seem to impact the fetal or obstetrical prognosis. Studies involving larger cohorts are required to confirm these data and to indicate this technique in pregnant women. Considering the benefit for the patient and the low risk incurred on both fetal and obstetrical levels, it appears reasonable to discuss the indication of SLN on a case-by-case basis in multidisciplinary oncologic meetings.

Morbidity of rectosigmoid resection in cytoreductive surgery for ovarian cancer. Risk factor analysis.

AIM: Rectosigmoid resection is often performed during cytoreductive surgery for ovarian cancer, to achieve the goal of no residual tumour. Here, we evaluated the morbidity associated with rectosigmoid resection and the underlying risk factors. METHODS: We retrospectively assessed consecutive patients managed with rectosigmoid resection during cytoreductive surgery for ovarian cancer at our centre in Paris, France, between 2005 and 2013. All previously identified risk factors were analysed. Major complications were defined as grade III-IV in the Clavien-Dindo classification. RESULTS: Of 228 patients, 116 had primary and 112 interval surgery; 43/228 [18.9%]; experienced major complications, and these were more common after primary surgery [24.1% vs. 13.4%, p = .04]. The 69 patients who had rectosigmoid resection [33 primary vs. 36 interval surgery, p = .32] had a higher morbidity rate compared to the other patients [30.4% vs. 14.6%, p = .006]. The anastomotic leakage rate was 2.89%. By multivariate logistic regression, independent risk factors for morbidity were postmenopausal status [adjusted odds ratio (aOR), 13.7; 95% confidence interval (95%CI), 1.2;161.9], surgery after neoadjuvant chemotherapy [aOR, 4.4; 95%CI, 1.1;18.8], and peritoneal stripping of the left; paracolic gutter [aOR, 11.3; 95%CI, 2.3;54.3]. CONCLUSION: The morbidity of rectosigmoid resection during cytoreductive surgery for ovarian cancer seems acceptable. Ileostomy does not seem associated with a lower risk of major complications or adjuvant bevacizumab with a higher complication rate.

Tocilizumab for the treatment of birdshot uveitis that failed interferon alpha and anti-tumor necrosis factor-alpha therapy: two cases report and literature review.

Biotherapies appear as potential drugs for the treatment of inflammatory noninfectious uveitis. In this report, we show that tocilizumab, an anti-IL-6 agent, greatly improved two patients with birdshot chorioretinopathy refractory to conventional immunosuppressive drugs, interferon α2a, and anti-TNFα agents. After a follow-up of 22 months, patients exhibited an improvement of both visual acuity and macular edema. A corticosteroid-sparing effect was achieved in both cases.

Upper outer boundaries of the axillary dissection. Result of the SENTIBRAS protocol: Multicentric protocol using axillary reverse mapping in breast cancer patients requiring axillary dissection.

BACKGROUND: Two thirds of node-positive breast cancer patients have limited pN1 disease and could benefit from a less extensive axillary lymph node dissection (ALND). METHODS: 172 breast cancers patients requiring an ALND were prospectively enrolled in the Sentibras Protocol of Axillary Reverse Mapping (ARM). Radioisotope was injected in the ipsilateral hand the day before surgery. ALND was standard. Removed lymph nodes were classified into non radioactive nodes and radioactive nodes (ARM nodes). Among ARM nodes, nodes located in the upper outer part of the axilla, above the second intercostal brachial nerve and lateral to the lateral thoracic vein were identified as "zone D ARM nodes". The main objective was: feasibility of identification of the zone D ARM nodes. Secondary objectives were: metastatic involvement and lymphedema rate. RESULTS: 100% of patients had ARM nodes identified. The "zone D ARM nodes" were identified in 92% of cases. The rate of metastatic nodes was 60% in the all cohort, 31% in ARM nodes and 9% in zone D ARM nodes. Among those, metastatic rate was 6% in patients undergoing ALND for a positive sentinel node biopsy, 6% in case of primary ALND versus 14% after neo-adjuvant chemotherapy (p < 0.05). After 34 months of median follow up, 27% of interviewed patients had a lymphedema. CONCLUSION: The ARM technique reliably identifies the "zone D ARM nodes". These nodes can also easily be identified using knowledge of axillary anatomy. In selected patients, a selective ALND sparing the zone D ARM nodes could be performed.
