In 2018, around 382,100 new cases of endometrial cancer (EC) were reported worldwide, accounting for about 4.4% of all new cases of cancer in women. In France, in 2018, the EC is the first gynecological cancer in incidence and the fourth cancer in women. The rationale for the therapeutic management of EC is based on the estimation of a theoretical risk of recurrence and lymph node metastasis using MRI and preoperative biopsy criteria. However, lymph node status remains the determining factor of adjuvant treatment. In order to reduce the morbidity of lymphadenectomy, the concept of sentinel lymph node biopsy (SLN) has been developed. The SLN technique has evolved in recent years, thanks to the advent of robotics and the creation of fluorescence detection cameras. It has been shown that detection of SLN with Indocyanine Green (ICG) allows for more frequent bilateral migration of 88 to 100% and better detection of pelvic GS in 97% of cases with a decrease in morbidity. Recently, in view of the absence of a therapeutic role of lymph node staging, the operational risks and the delay of adjuvant treatments, in case of pelvic lymph node metastasis on definitive histological examination, the question of secondarily performing paraaortic lymphadenectomy arises. The SLN procedure, extended to all early-stage endometrial cancers, should lead to a major reduction in the use of secondary staging and better adaptation of adjuvant therapy.

Evaluate the concordance between the renal lesions biopsy's histology and the final histology of the surgical specimen according to histological subtype, and search for predictive factors of non-concordance.

Despite being a standard of care in several cancers, sentinel lymph node (SLN) is not widespread in digestive cancers. European guidelines do not recommend its use for any digestive cancers. Particularity of the lymphatic vessel, intimately linked to blood vessel, may explain part of this phenomenon. Nevertheless, more indication could arise in the near future with the early diagnosis of tumor induced by cancer screening. Ruling out the lymphatic invasion could allow preserving the organ currently resected because of risk of lymph node positivity. This procedure is well studied in early gastric cancer in Korea and Japan. Several study have demonstrated that, a dual-tracer (isotopic and dye) allows to accurately identify the SLN. A randomized phase 3 trial is currently active in Korea to evaluate the oncological results of the procedure. Similar indication could arise for T1 tumor of the low-rectum, but currently available data are insufficient to recommend its use outside of a study. SLN may also be used to detect aberrant lymphatic drainage (rectum, ileum) but have been tested so far only in a few dozen of patients. Finally, SLN is disappointing in colon cancer, due to its low sensitivity and the absence of modification of the surgical procedure induced.

Lymph node status is the most important prognostic factor of survival in women with early stage cervical cancer. Sentinel lymph node (SLN) biopsy is an accurate method for the assessment of lymph nodal involvement in early-stages cervical cancer and has been increasingly used instead of systematic pelvic lymph node dissection (PLND). Less-radical lymph node dissection decreases the associated morbidity of PLND, especially the risk of lower-leg lymphoedema, which affects severely patient quality of life. SLN biopsy allows nodes ultrastaging and provides supplementary histological information by increasing the detection of tumor low-volume (isolated tumors cells and micrometastases). Moreover, SLN biopsy provides accurate anatomical information on pelvic lymphatic drainage pathway by identifying nodes outside of routine lymphadenectomy areas. Selection of a population at low-risk of nodal metastasis, a minimal training, and simple rules may ensure a low false negative rate. Several studies have shown that SLN mapping in these patients is feasible, with excellent detection rates and sensitivity. Combined detection with technetium-99 and blue dye has been widely used but recently, there has been increasing interest in the use of fluorescent dies such as indocyanine green (ICG) which would improve SLN detection. Although recent international guidelines recommend performing SLN biopsy in addition to PLND, SLN biopsy alone is not the gold-standard yet due to lack of prospective evidence, especially on long-term oncological safety. Some points remain controversial such as the low accuracy of intraoperative SLN status assessment by frozen section and the impact of micrometastasis on prognostic. The prospective randomized clinical trial SENTICOL III will answer to these problematics.

Colorectal cancer is the most common digestive cancer. The objectives of this study was to analyse the frequency, aetiologies, and the therapeutic and progressive aspects of colorectal cancer in young adults in Burkina Faso. This study was a 10-years descriptive study conducted in 2 regional hospitals in Burkina Faso. It included all patients aged 20 to 45 years admitted to these two hospitals for colon cancer or rectal cancer during the study period. A total of 116 patients were included, which was 39.2% of all patients admitted for colorectal cancer during the same period. The average age of the included patients was 35.4 years old. There were 70 male patients (60.3%). Seven patients had a history of chronic inflammatory bowel disease, and six had a family history of colon cancer. The average consultation time was 6.2 months. In 25 cases (19.9%), the cancer was discovered in the context of an abdominal emergency. Ninety-two patients (79.3%) were diagnosed at stage 3 or stage 4 according to the TNM Staging System. The most common histological type was adenocarcinoma (103 cases, 88.9%). Therapeutically, surgery was performed on 87 patients (75%) and chemotherapy was used in 37 cases (31.9%). Sixteen patients received radiotherapy. The intra operative mortality rate was 4.6%. The 5-year survival rate was 17%. In conclusion, colorectal cancer in young adults occurs without obvious risk factors in Burkina Faso. Mortality remains high because of the limited therapeutic arsenal.

Sentinel lymph node biopsy (SLNB) has been initially developed for melanoma and breast cancers. Its application in head and neck cancers is recent, probably due to the complexity of the lymphatic drainage, the proximity between the primary tumor and the lymph nodes and the critical anatomical structures (such as the facial nerve). In onco-dermatology, SLNB is validated in head and neck surgery for melanoma with Breslow thickness up to 1mm or ulceration, Merkel carcinoma and high-risk squamous cell carcinoma. Considering the malignancies of the upper aerodigestive tract, the feasibility and oncologic safety of SLNB are now established for T1-T2N0 oral and oropharyngeal squamous cell carcinomas. Thus, it could allow patients with negative sentinel nodes to avoid an unnecessary neck dissection, leading to a decrease of morbidity with an quality of life improvement. For some primary locations (e.g., anterior floor of the mouth) with high proximity between tumor and lymph nodes, it is recommended to remove the tumor before the SLNB so as to improve the detection. New techniques of detection are currently being developed with intra-operative procedures and new tracers (such as tilmanocept), leading to a better accuracy of detection and, probably, new indications.

In colorectal cancer staging, pathologic lymph node analysis is a crucial information for the clinician and must be performed with a maximal level of accuracy. Therefore, the surgical sample analysis needs harvesting of as many lymph nodes as possible from the mesentery. In this study, we analysed the influence of a series of clinical and pathological factors which could influence lymph node harvesting. A total of 239 patients were included in our study. The factors with a statistically significant influence on lymph node collection (pinferior to0.05) were the age, gender of the patient, size of the primitive neoplasm, size of the surgical specimen, expertise of the surgeon and the pathology department. The presence of a radiochimiotherapy did not have any influence on the lymph node collection. This study highlights the importance of lymph node harvesting in colorectal surgical specimens of colo-rectal cancers.

Gross examination is an essential step for pathological report of a surgical sample. It includes the description of the surgical specimen and their disease(s), the precise and exhaustive sampling of tumoral and adjacent tumoral tissue areas. This examination requires a good knowledge of the updated pTNM classification. Pathologists from the PATTERN group have collaborated with thoracic surgeons, under the auspices of the Sociéte française de pathologie, to propose guidelines for resected specimen management. This approach fits into the context of the elaboration of structured pathological report proposed by the société française de pathologie, which is necessary for a standardized management of patients.

Adjuvant radiotherapy is a key treatment in early-stage breast cancer. The meta-analysis by the Early Breast Cancer Trialist's Collaborative Group (EBCTCG) has demonstrated a decreased risk of locoregional relapse and death after whole-breast radiotherapy. Prophylactic lymph nodes irradiation in breast cancer has also proven to be beneficial in several therapeutic trials. At a time when three-dimensional conformal radiotherapy has become the standard procedure and with the development of intensity-modulated radiation therapy, defining nodal volumes is essential and practices should be harmonized to assess and compare the efficiency and toxicity of radiotherapy. Furthermore, the indication of lymph nodes irradiation has to take into account the risk/benefit balance as expanding the irradiated volume can increase radio-induced toxicity. Selection of patients receiving this treatment is essential. The aim of this update is to define nodal volumes, to precise the indications of their irradiation and to present the expected benefits as well as the potential side effects.

This article is a review of the literature that aims to clarify the place of systemic and locoregional treatments, with a focus on radiotherapy and surgery in the management of patients with oligometastatic kidney cancer. We have selected articles of interest published in Medline indexed journals. We have also analysed the related guidelines: National Comprehensive Cancer Network (NCCN) 2019, European Association of Urology (EAU) 2019, European Society of Medical Oncology (ESMO) 2019, Association française d'urologie (Afu) 2018 as well as some abstracts of international congresses. The main treatments evaluated were surgery and radiotherapy. We defined the different scenarios conventionally encountered in clinical practice. The evolution of systemic therapies (increased overall survival and response rate) is likely to increase the number of patients potentially accessible to locoregional treatments. The complete analysis of the literature underlines the place of locoregional treatments whatever the scenarios mentioned. Data on stereotactic radiotherapy found a local control rate consistently above 70% in all studies with a maintained response and positive impact on overall survival and progression-free survival. The improvement of overall survival by sequential use of the various therapeutic classes confirms the need for optimization of locoregional treatments in the model of oligometastatic kidney cancer. The dogma of radioresistance must definitely be set aside with current irradiation techniques.

In March 2019, Harter et al. published the results of the LION study (Lymphadenectomy in patients with advanced ovarian neoplasms) which raises the question of pelvic and para-aortic lymphadenectomy for patients with advanced-stage epithelial ovarian cancer (EOC). These results influenced the new French recommendations published in December 2018 by the French National Cancer Institute (INCa). Thus, it no longer seems consistent to perform a systematic lymphadenectomy for patients for whom there is no argument for nodal involvement, when a macroscopic complete peritoneal cytoreductive surgery has been performed. The question of preoperative lymph node assessment is therefore essential, whereas more than half of the patients in the LION study had metastatic lymph node involvement that was histologically proven. For the assessment of lymph node status by imaging, superior sensitivity for Positron Emission Tomography is demonstrated in comparison with CT-scan or Magnetic Resonance Imaging. Nevertheless, thoraco-abdomino-pelvic CT-scan with contrast injection remains the gold standard for this indication. In the absence of suspected involvement, supra-renal, mesenteric, coelio-hepatic, and cardio-phrenic lymphadenectomy are not recommended. Lymphadenectomies should always be performed in the other situations of EOC management apart from the rare case of stage 1 expansile subtype mucinous carcinoma. The aim of this review is to discuss lymphadenectomy indications for the surgical management of EOC by taking into account new data from the scientific literature.

Osteosarcoma is the most common malignant bone tumor before 25 years of age. Response to neoadjuvant chemotherapy determines continuation of treatment and is also a powerful prognostic factor. There are currently no reliable ways to evaluate it early. The aim is to develop a method to predict the chemotherapy response using radiomics from pre-treatment MRI.

The European Society of Gynaecologic Oncology (ESGO) guidelines cover the whole field of common clinical situations in gynecologic oncology. Their elaboration follows a strict process including a systematic review of the literature, the setting up of a group of expert on the basis of scientific production, geographical balance, and multidisciplinarity, and an external review by users and patients. The recommendations for the management of vulvar cancer were elaborated in 2015 and published in 2017. They are available in open access on the ESGO website, and can be incorporated in clinical practice using the free ESGO guidelines smartphone application. This review is a selection of the sections addressing the diagnostic and strategical aspects of the management of lymph nodal disease in vulvar cancer. An additional review of the recent literature published since 2015 has been carried out. The management of nodal disease in vulvar cancer encompasses a diagnostic and a therapeutic component. Clinical and imaging assessment still play a major role, whilst the identification of the sentinel node is currently a mainstay of assessment of the nodal status in early vulvar cancer. The therapeutic component is based on the rational use of full lymph node dissection and (chemo)radiation.

Development of acral malignant melanoma in Mal de Meleda is highly unusual. As far as we could ascertain, to date, only 10 previous cases have been published. Herein, we report a new case.

The increasing indications of cytostatic biotherapies and the improvement in metastatic surgery have profoundly changed the management of metastatic colorectal cancer (mCRC) patients. Then the development of prognostic and predictive scores would be useful to stratify the treatments. Tumor radiological measurement is crucial to estimate treatment efficacy, and to predict pathological response and survival, and this parameter is included when a prognostic score is developed. But the standard size-based radiologic criteria, the Response Evaluation Criteria in Solid Tumors (RECIST), was designed ten years ago to assess tumor volume reduction after cytotoxic chemotherapy only. Nowadays, this method may be insufficient for mCRC patients. The aim of this review is to describe the different radiological assessments evaluated in mCRC, and to underline their correlations with patient's survival and pathologic response. A better knowledge of these radiological measurements would help to better integrate them in prospective trials, and in the prognostic and predictive scores. The choice of radiological measurement could be discussed regarding patient's situation, combining different approaches, and assessing tumoral mass quantification.

We here report a case of bladder urothelial carcinoma, a rare tumor in subjects less than 40 years, as well as our therapeutic experience. The study involved a 37-year old patient with a history of urinary tract infection and of staying at a riparian area (bilharzia) presenting with hypogastralgia and total macroscopic hematuria. Clinical and paraclinical assessment showed voluminous bladder mass suggesting infiltrative tumor without local or distant lymph node or organic involvement. Surgical management was based on resection of bladder tumor and biopsy followed by total cystectomy with substitutive ileal enterocystoplasty. The postoperative course was uneventful. The patient also underwent adjuvant chemotherapy and vitamin B-12 therapy. Clinical and paraclinical assessment, performed after 6 and 12 months, showed no recurrence.

Schwannoma is a neurogenic tumor originating from Schwann cells. When considering the thoracic region, it is most commonly found in the mediastinum. It commonly appears as a solitary lesion and pleural involvement is extremely rare. We here report the case of a 44-year old woman with benign primitive schwannoma of the pleura whose lesion was detected after radiological assessment for chest pain and dyspnea. The patient underwent complete surgical resection using video-assisted thoracoscopic surgery (VATS) technique. The anatomopathological study showed benign primitive schwannoma of the pleura.
