BACKGROUND: While total hysterectomy and bilateral salpingo-oophorectomy without lymph node staging are standard for low- and intermediate-risk endometrial cancer, certain histopathologic factors revealed after surgery can necessitate additional interventions. Our study assessed the influence of sentinel lymph node biopsy on postoperative decision-making. MATERIALS AND METHODS: In the SENTRY trial (July 2021 - February 2023), we enrolled patients with International Federation of Gynaecology and Obstetrics (FIGO) stage IA-IB low-grade endometrioid endometrial cancer. Laparoscopic sentinel lymph node mapping using indocyanine green was performed alongside total hysterectomy with bilateral salpingo-oophorectomy. Subsequent management changes based on sentinel lymph node biopsy results were evaluated. The trial was registered at ClinicalTrials.gov (NCT04972682). RESULTS: Of the 100 enrolled participants, a bilateral detection rate of 91% was observed with a median detection time of 10 min (interquartile range 8-13 min). Sentinel lymph node metastases were found in 8% (N = 8) of participants. Postoperative FIGO staging increased in 15% (N = 15) and decreased in 5% (N = 5) of patients. Sentinel lymph node biopsy results altered the adjuvant treatment plan for 20% (N = 20): external beam radiotherapy was omitted in 12% (N = 12) while 6% (N = 6) had external beam radiotherapy +/- systemic chemotherapy added due to sentinel lymph node metastases. In 2% (N = 2), the external beam radiotherapy field was expanded with the paraaortic region. No intraoperative complications were reported and no 30-day major morbidity and mortality occurred. Throughout a median follow-up of 14 (95% CI 12-15 months, neither patient-reported lymphedema nor pelvic recurrence surfaced in the cohort. CONCLUSIONS: Sentinel lymph node biopsy using indocyanine green is a safe procedure and allows tailoring adjuvant therapy in presumed low- and intermediate-risk endometrial cancer. It assists in avoiding external beam radiotherapy overtreatment and introducing additional modalities when necessary.

OBJECTIVE: The purpose of this study was to establish a consensus on the surgical technique for sentinel lymph node (SLN) dissection in cervical cancer. METHODS: A 26 question survey was emailed to international expert gynecological oncology surgeons. A two-step modified Delphi method was used to establish consensus. After a first round of online survey, the questions were amended and a second round, along with semistructured interviews was performed. Consensus was defined using a 70% cut-off for agreement. RESULTS: Twenty-five of 38 (65.8%) experts responded to the first and second rounds of the online survey. Agreement ≥70% was reached for 13 (50.0%) questions in the first round and for 15 (57.7%) in the final round. Consensus agreement identified 15 recommended, three optional, and five not recommended steps. Experts agreed on the following recommended procedures: use of indocyanine green as a tracer; superficial (with or without deep) injection at 3 and 9 o'clock; injection at the margins of uninvolved mucosa avoiding vaginal fornices; grasping the cervix with forceps only in part of the cervix is free of tumor; use of a minimally invasive approach for SLN biopsy in the case of simple trachelectomy/conization; identification of the ureter, obliterated umbilical artery, and external iliac vessels before SLN excision; commencing the dissection at the level of the uterine artery and continuing laterally; and completing dissection in one hemi-pelvis before proceeding to the contralateral side. Consensus was also reached in recommending against injection at 6 and 12 o'clock, and injection directly into the tumor in cases of the tumor completely replacing the cervix; against removal of nodes through port without protective maneuvers; absence of an ultrastaging protocol; and against modifying tracer concentration at the time of re-injection after mapping failure. CONCLUSION: Recommended, optional, and not recommended steps of SLN dissection in cervical cancer have been identified based on consensus among international experts. These represent a surgical guide that may be used by surgeons in clinical trials and for quality assurance in routine practice.

OBJECTIVE: The aim of this study was to determine how often changes the stage of the tumour in definitive histology against preoperative clinical stage in patient cohort with diagnosed endometrial cancer. METHODS: We evaluated prospectively a cohort of 166 patients with endometrial cancer. They all underwent abdominal hysterectomy, bilateral salpingo-oophorectomy, sentinel lymph node biopsy. Patients with high-risk tumours also pelvic lymfadenectomy. We collected data of preoperative diagnostic biopsy and postoperative definitive histology. The data were statistically processed. RESULTS: Detection of sentinel lymph node was successful in 71.1%, bilateral successful detection was in 40.6%. Discrepancy of tumour grade between preoperative biopsy and definitive histology was generally 31.4%. Upgrading of the tumour was in 22 (14.4%) cases, downgrading in 26 (17%) cases. Upgrade from low-risk to high-risk group of tumours was noticed in eight cases. Histopathological tumour type changed in 6.6%, 4.6% moved to histopathologic high-risk group. The tumour stage changed in definite histology in 57.3%, in 19.2% of cases moved from stage low/intermediate-risk group to intermediate-high/high-risk disease group. CONCLUSION: Correct assessment of preoperative clinical stage and histological grade of endometrial cancer is burdened with a high inaccuracy rate. A lot of cases is up-staged after surgical staging and moved to intermediate-high/high-risk disease group. Results confirm the importance of oncogynaecologic centre II. evaluation of histopathology findings from diagnostic biopsies made in referring hospitals. Sentinel lymph node biopsy should be performed even in clinically low/intermediate-risk disease group.

We report a very unusual case of melanocytic neoplasm appearing clinically as a 0.5-cm dome-shaped pigmented papule on the chest of a 63-year-old man. Microscopically, it was an asymmetric, entirely dermally based neoplasm characterized by a multinodular, vaguely plexiform architecture composed of moderately pleomorphic spindled melanocytes with ample, dusty pigmented cytoplasm and scattered multinucleated cells. The tumor cells were strongly positive for Melan-A, HMB45, S100, and PRAME, whereas p16 showed diffuse nuclear loss. β-catenin presented a strong and diffuse cytoplasmic staining, while nuclei were negative. Despite an increased cellularity, mitotic count was low (1/mm 2 ). Fluorescence in situ hybridization revealed no copy number alteration in melanoma-related genes ( CDKN2A, MYB, MYC, CCND1 and RREB1 ). DNA and RNA sequencing identified KIT c.2458G>T and APC c.6709C>T mutations. No further genetic alteration was detected including TERT-promoter (TERT-p ) hot-spot mutation. A re-excision was performed. A sentinel lymph node biopsy was negative. Clinical investigations revealed no extracutaneous involvement. The patient is disease-free after a follow-up period of 8 months. Given the peculiar morphologic and molecular findings, we hypothesize the lesion may represent a novel subtype of an intermediate grade melanocytic tumor (melanocytoma).

BACKGROUND: Targeted axillary dissection (TAD) is an established method for axillary staging in patients with breast cancer after neoadjuvant chemotherapy (NAC). TAD consists of sentinel lymph node biopsy and initially pathological lymph node excision, which must be marked by a reliable marker before NAC. METHODS: The IMTAD study is a prospective multicentre trial comparing three localisation markers for lymph node localisation (clip + iodine seed, magnetic seed, carbon suspension) facilitating subsequent surgical excision in the form of TAD. The primary outcome was to prospectively compare the reliability, accuracy, and safety according to complication rate during marker implantation and detection and marker dislodgement. RESULTS: One hundred eighty-nine patients were included in the study-in 135 patients clip + iodine seed was used, in 30 patients magnetic seed and in 24 patients carbon suspension. The complication rate during the marker implantation and detection were not statistically significant between individual markers (p = 0.263; p = 0.117). Marker dislodgement was reported in 4 patients with clip + iodine seed localisation (3.0%), dislodgement did not occur in other localisation methods (p = 0.999). The false-negativity of sentinel lymph node (SLN) was observed in 8 patients, the false-negativity of targeted lymph nodes (TLN) wasn´t observed at all, the false-negativity rate (FNR) from the subcohort of ypN + patients for SLN is 9.6% and for TLN 0.0%. CONCLUSION: The IMTAD study indicated, that clip + iodine seed, magnetic seed and carbon suspension are statistically comparable in terms of complications during marker implantation and detection and marker dislodgement proving their safety, accuracy, and reliability in TAD. The study confirmed, that the FNR of the TLN was lower than the FNR of the SLN proving that the TLN is a better marker for axillary lymph node status after NAC. TRIAL REGISTRATION: NCT04580251. Name of registry: Clinicaltrials.gov. Date of registration: 8.10.2020.

INTRODUCTION: The standard procedure in cervical cancer is radical hysterectomy and pelvic lymphadenectomy (PLND). Because of the increasing age of women bearing children, fertility has become a major challenge. We present pregnancy results after less radical fertility-sparing surgery in women with IA1, LVSI positive, IA2 and IB1 (<2 cm, infiltration less than half of the cervical stroma). MATERIALS AND METHOD: All women (n = 91) underwent laparoscopic sentinel lymph node mapping with frozen section followed by PLND and "selective parametrectomy" (removal of afferent lymphatic channels from the paracervix) if sentinel nodes (SLN) are negative. If lymph nodes were verified negative by definitive histopathology, patients were treated by simple trachelectomy (IB1) or large cone (IA1/IA2) biopsy 1 week after primary surgery. RESULTS: From 1999 to 2018, 91 women were enrolled in the study (median age 29.1 years, range 21-40). Fertility was spared in 76 (83.5%) women; 13 (17.1%) women did not plan future pregnancy and 63 (82.9%) had pregnancy desires. Fifty-four of 63 women conceived (pregnancy rate 85.7%) and 48 of 63 delivered 58 babies (delivery rate 76.2%). Thirty-nine women delivered in term (67.2%): 13 women between 32 and 36 + 6 weeks of pregnancy, 3 between 28 and 31 + 6 weeks and 3 between 24 and 27 + 6 weeks. Only one woman still plans pregnancy. One woman is currently pregnant. CONCLUSION: The goal of fertility-sparing surgery is to produce good oncological results and promising pregnancy outcomes. Pregnancy results after less radical fertility-sparing procedures show promise (pregnancy rate 82.9% and delivery rate 76.2%).

INTRODUCTION: Triple negative breast carcinomas (TNBC) account for approximately 15-20% of all breast carcinomas. This subtype is characterised by an unfavourable prognosis with early locoregional recurrence a metastases. Only few studies have focused on the impact of local surgery on the overall therapeutic outcome. However, decisions are difficult to make in the case of TNBC, and no particular molecular subtype or marker exists that would make the decision-making process easier. The aim of our retrospective study was to analyse the TNBC surgical management outcomes at EUC Clinic in Zlin. METHODS: 440 women with breast carcinoma were operated on at EUC Clinic from 2014 to 2016, including 29 patients with TNBC; bilateral carcinoma was present in one case. Neoadjuvant chemotherapy (NAC) was indicated in 6 cases. The tumour centre was marked with a clip. The extent of surgery depended on the residual size of the tumour. Sentinel lymph node biopsy was indicated in clinically negative lymph nodes; further management followed the Z0011 study if the biopsy was positive. Axillary lymph node dissection was performed after NAC. In all cases, surgery was followed by systemic chemotherapy, and by radiotherapy in the case of breast-conserving procedures. RESULTS: The group included 29 women and one patient with bilateral carcinoma, i.e. 30 cases of TNBC. Mean age was 57 years and median age was 55.5 years. Mean follow-up was 62.9 months, with the median of 69.9 month. NAC was indicated in 6 patients; complete pathological response was achieved in one case. NAC was followed by mastectomy in 5 cases including a bilateral procedure in one case, and by breast-conserving surgery in one case. Axillary dissection was performed in all cases. Breast-conserving surgery and sentinel node biopsy predominated in the group (16 cases). Local recurrence was observed in 4 cases, 2 times as an isolated local recurrence after one year and 2 times as part of generalization, always after mastectomy. Six patients died of generalized disease. No regional recurrence was observed. CONCLUSION: TNBC is characterised by a worse prognosis and a higher rate of local recurrence. As confirmed by our study, the results of breast-conserving surgery can be comparable to those of radical procedures, and thus radical surgery should be indicated prudently.

OBJECTIVE: Comparison of systems to detect sentinel lymph node in endometrial carcinoma using indocyanine green. Robotic Firefly Da Vinci fluorescence imaging system (Intuitive Surgical Inc., Sunnyvale, CA, USA) vs. laparoscopic Novadaq Pinpoint near-infrared imaging system (Novadaq, Ontario, Canada). MATERIAL AND METHOD: Fifteen patients with stage I endometrial cancer underwent sentinel lymph node biopsy after intracervical application of indocyanine green. For all of them, the detection was performed sequentially using both evaluated devices. The detection rate, identification match and extent of imaging of the lymphatic system were evaluated. RESULTS: The detection rate of both systems verified on a set of patients was identical, the detected sentinel nodes were identical, and the lymphatic system was shown to the same extent. The quality of the display and overall user-friendliness is different due to the applied technologies. CONCLUSION: Both systems used in minimally invasive surgery provide excelent perioperative imaging of the lymphatic system.

BACKGROUND: In cervical cancer, presence of lymph-node macrometastases (MAC) is a major prognostic factor and an indication for adjuvant treatment. However, since clinical impact of micrometastases (MIC) and isolated tumor-cells (ITC) remains controversial, we sought to identify a cut-off value for the metastasis size not associated with negative prognosis. METHODS: We analyzed data from 967 cervical cancer patients (T1a1L1-T2b) registered in the SCCAN (Surveillance in Cervical CANcer) database, who underwent primary surgical treatment, including sentinel lymph-node (SLN) biopsy with pathological ultrastaging. The size of SLN metastasis was considered a continuous variable and multiple testing was performed for cut-off values of 0.01-1.0 mm. Disease-free survival (DFS) was compared between N0 and subgroups of N1 patients defined by cut-off ranges. RESULTS: LN metastases were found in 172 (18%) patients, classified as MAC, MIC, and ITC in 79, 54, and 39 patients, respectively. DFS was shorter in patients with MAC (HR 2.20, P = 0.003) and MIC (HR 2.87, P < 0.001), while not differing between MAC/MIC (P = 0.484). DFS in the ITC subgroup was neither different from N0 (P = 0.127) nor from MIC/MAC subgroups (P = 0.449). Cut-off analysis revealed significantly shorter DFS compared to N0 in all subgroups with metastases ≥0.4 mm (HR 2.311, P = 0.04). The significance of metastases <0.4 mm could not be assessed due to limited statistical power (<80%). We did not identify any cut-off for the size of metastasis with significantly better prognosis than the rest of N1 group. CONCLUSIONS: In cervical cancer patients, the presence of LN metastases ≥0.4 mm was associated with a significant negative impact on DFS and no cut-off value for the size of metastasis with better prognosis than N1 was found. Traditional metastasis stratification based on size has no clinical implication.

INTRODUCTION: In the last decade, the view of endometrial cancer has shifted enormously, and the surgical approach or lymph node staging has changed significantly. We are presenting these changes with the University Hospital Brno Oncogynecology centers results in the years 2012-2021 in the actual national and European guidelines context. METHODS: The retrospective unicentric observational study, national and European guidelines review. RESULTS: In the observation period, 715 endometrial cancer patients were treated in our clinic, and 636 of them underwent surgical treatment (89%). Concerning lymph node staging, firstly, there is a clear trend of expanding lymphadenectomy to the paraaortic area, followed by the sentinel node bio-psy introduction in the years 2018-2019, and finally, the complete transition to this method as the main staging procedure in 2021, when this examination was performed in 73% of surgeries, even with high-risk cancers limited to the uterus. Within the sentinel node bio-psy expansion, a gradual decrease in laparotomy approach (maximum 41% in 2016, 18% in 2021), and blood loss (2012-2019 median 100 mL, with a decrease to 50 mL in 2020-2021) was evident. A hospitalization length stabilized at a median of 5-6 days. CONCLUSIONS: Surgical treatment of endometrial cancer has become a minimally invasive procedure for the majority of patients, the average blood loss and hospitalization length have decreased. Sentinel node bio-psy has become the preferred lymph node staging method.
