Fifty-five cases of hepatic alveolar echinococcosis combined with lymph node metastasis: A retrospective study.

BACKGROUND: Lymph node metastasis is a specific type of metastasis in hepatic alveolar echinococcosis (AE). Currently, there is a scarcity of describing the clinical characteristics and lymph node metastasis rules of patients with hepatic AE combined with lymph node metastasis and its mechanism and management are still controversial. Radical hepatectomy combined with regional lymph node dissection is a better treatment. AIM: To analyse the clinical features of hepatic AE combined with lymph node metastasis to explore its treatment and efficacy. METHODS: A total of 623 patients with hepatic AE admitted to the First Affiliated Hospital of Xinjiang Medical University from 1 January 2012 to 1 January 2022 were retrospectively analysed. Fifty-five patients with combined lymph node metastasis were analysed for their clinical data, diagnosis and treatment methods, follow-up efficacy, and characteristics of lymph node metastasis. Finally, we comparatively analysed the lymph node metastasis rates at different sites. Categorical variables are expressed as frequencies and percentages, and the analysis of difference was performed using the χ 2 test. The Bonferroni method was used for pairwise comparisons when statistical differences existed between multiple categorical variables. RESULTS: A lymph node metastasis rate of 8.8% (55/623) was reported in patients with hepatic AE, with a female predilection (69.1%) and a statistically significant sex difference (χ 2 = 8.018, P = 0.005). Of the 55 patients with lymph node metastasis, 72.7% had a parasite lesion, neighbouring organ invasion, and metastasis stage of P3N1M0 and above, of which 67.3%, 78.2%, and 34.5% of hepatic AE lesions invaded the bile ducts, blood vessels, and distant metastases, respectively. Detection rates of lymph node metastasis of 16.4%, 21.7%, and 34.2% were reported for a preoperative abdominal ultrasound, magnetic resonance imaging, and computed tomography examinations. All patients were intraoperatively suspected with enlarged lymph nodes and underwent radical hepatectomy combined with regional lymph node dissection. After surgery, a routine pathological examination was conducted on the resected lymph nodes. A total of 106 positive lymph nodes were detected in six groups at various sites, including 51 single-group metastasis cases and four multi-group metastasis cases. When the metastasis rates at different sites were statistically analysed, we observed that the metastasis rate in the para-hepatoduodenal ligament lymph nodes was significantly higher than that of the other sites (χ 2 = 128.089, P = 0.000 < 0.05). No statistical difference was observed in the metastasis rate between the five other groups. Clavien-Dindo grade IIIa complication occurred in 14 cases, which improved after administering symptomatic treatment. Additionally, lymph node dissection-related complications were not observed. Recurrence after 2 years was observed in one patient. CONCLUSION: Lymph node metastasis is a rare form of metastasis in hepatic AE, which is more frequent in women. Para-hepatoduodenal ligament lymph nodes are commonly observed. Radical hepatectomy combined with regional lymph node dissection is a safe, effective, and feasible treatment for liver AE combined with lymph node metastasis.

Prevalence and quantity of lymph nodes at mediastinal stations in patients with lung cancer: lessons from 181 bilateral mediastinal lymphadenectomies.

BACKGROUND: This study evaluated the prevalence and quantity of lymph nodes at particular stations of the mediastinum in patients with lung cancer. These data are important to radiologists, pathologists, and thoracic surgeons because they can serve as a benchmark when assessing the completeness of lymph node dissection. However, relevant data in the literature are scarce. METHODS: Data regarding the number of lymph nodes derived from two randomised trials of bilateral mediastinal lymph node dissection, the BML-1 and BML-2 study, were included in this analysis. Detectable nodes at particular stations of the mediastinum and the number of nodes at these stations were analysed. RESULTS: The mean number of removed nodes was 28.67 (range, 4-88). Detectable lymph nodes were present at stations 2R, 4R, and 7 in 93%, 98%, and 99% of patients, respectively. Nodes were rarely present at stations 9 L (33%), and 3 (35%). The largest number of nodes was observed at stations 7 and 4R (mean, 5 nodes). CONCLUSION: The number of mediastinal lymph nodes in patients with lung cancer may be greater than that in healthy individuals. Lymph nodes were observed at stations 2R, 4R, and 7 in more than 90% of patients with lung cancer. The largest number of nodes was observed at stations 4R and 7. Detectable nodes were rarely observed at stations 3 and 9 L. TRIAL REGISTRATION: ISRCTN 86,637,908.

A novel technique for NO.253 lymph node dissection and left colic artery preservation to avoid potential postoperative internal hernia in laparoscopic radical resection for rectal cancer.

BACKGROUND: The preservation of the left colic artery (LCA) has emerged as a preferred approach in laparoscopic radical resection for rectal cancer. However, preserving the LCA while simultaneously dissecting the NO.253 lymph node can create a mesenteric defect between the inferior mesenteric artery (IMA), the LCA, and the inferior mesenteric vein (IMV). This defect could act as a potential "hernia ring," increasing the risk of developing an internal hernia after surgery. The objective of this study was to introduce a novel technique designed to mitigate the risk of internal hernia by filling mesenteric defects with autologous tissue. METHODS: This new technique was performed on eighteen patients with rectal cancer between January 2022 and June 2022. First of all, dissected the lymphatic fatty tissue on the main trunk of IMA from its origin until the LCA and sigmoid artery (SA) or superior rectal artery (SRA) were exposed and then NO.253 lymph node was dissected between the IMA, LCA and IMV. Next, the SRA or SRA and IMV were sequentially ligated and cut off at an appropriate location away from the "hernia ring" to preserve the connective tissue between the "hernia ring" and retroperitoneum. Finally, after mobilization of distal sigmoid, on the lateral side of IMV, the descending colon was mobilized cephalad. Patients'preoperative baseline characteristics and intraoperative, postoperative complications were examined. RESULTS: All patients' potential "hernia rings" were closed successfully with our new technique. The median operative time was 195 min, and the median intraoperative blood loss was 55 ml (interquartile range 30-90). The total harvested lymph nodes was 13.0(range12-19). The median times to first flatus and liquid diet intake were both 3.0 days. The median number of postoperative hospital days was 8.0 days. One patient had an injury to marginal arterial arch, and after mobolization of splenic region, tension-free anastomosis was achieved. No other severe postoperative complications such as abdominal infection, anastomotic leakage, or bleeding were observed. CONCLUSIONS: This technique is both safe and effective for filling the mesenteric defect, potentially reducing the risk of internal hernia following laparoscopic NO.253 lymph node dissection and preservation of the left colic artery in rectal cancer surgeries.

Multicentre randomized clinical trial on robot-assisted versus video-assisted thoracoscopic oesophagectomy (REVATE trial).

BACKGROUND: Surgery for oesophageal squamous cell carcinoma involves dissecting lymph nodes along the recurrent laryngeal nerve. This is technically challenging and injury to the recurrent laryngeal nerve may lead to vocal cord palsy, which increases the risk of pulmonary complications. The aim of this study was to compare the efficacy and safety of robot-assisted oesophagectomy (RAO) versus video-assisted thoracoscopic oesophagectomy (VAO) for dissection of lymph nodes along the left RLN. METHODS: Patients with oesophageal squamous cell carcinoma who were scheduled for minimally invasive McKeown oesophagectomy were allocated randomly to RAO or VAO, stratified by centre. The primary endpoint was the success rate of left recurrent laryngeal nerve lymph node dissection. Success was defined as the removal of at least one lymph node without causing nerve damage lasting longer than 6 months. Secondary endpoints were perioperative and oncological outcomes. RESULTS: From June 2018 to March 2022, 212 patients from 3 centres in Asia were randomized, and 203 were included in the analysis (RAO group 103; VAO group 100). Successful left recurrent laryngeal nerve lymph node dissection was achieved in 88.3% of the RAO group and 69% of the VAO group (P < 0.001). The rate of removal of at least one lymph node according to pathology was 94.2% for the RAO and 86% for the VAO group (P = 0.051). At 1 week after surgery, the RAO group had a lower incidence of left recurrent laryngeal nerve palsy than the VAO group (20.4 versus 34%; P = 0.029); permanent recurrent laryngeal nerve palsy rates at 6 months were 5.8 and 20% respectively (P = 0.003). More mediastinal lymph nodes were dissected in the RAO group (median 16 (i.q.r. 12-22) versus 14 (10-20); P = 0.035). Postoperative complication rates were comparable between the two groups and there were no in-hospital deaths. CONCLUSION: In patients with oesophageal squamous cell carcinoma, RAO leads to more successful left recurrent laryngeal nerve lymph node dissection than VAO, including a lower rate of short- and long-term recurrent laryngeal nerve injury.

Oesophageal cancer often requires complex surgery. Recently, minimally invasive techniques like robot- and video-assisted surgery have emerged to improve outcomes. This study compared robot- and video-assisted surgery for oesophageal cancer, focusing on removing lymph nodes near a critical nerve. Patients with a specific oesophageal cancer type were assigned randomly to robot- or video-assisted surgery at three Asian hospitals. Robot-assisted surgery had a higher success rate in removing lymph nodes near the important nerve without permanent damage. It also had shorter operating times, more lymph nodes removed, and faster drain removal after surgery. In summary, for oesophageal cancer surgery, the robotic approach may provide better lymph node removal and less nerve injury than video-assisted techniques.

Ex-situ Open Approach Spleen Preserving Splenic Hilum Lymphadenectomy.

Background: multiple studies showed important benefices arising from splenic preservation in patients with digestive cancer in general and gastric cancer in particular. The minimally invasive approach remains controversial in locally advanced gastric cancer cases whilst the open approach still has an important role. This paper's aim is to describe and present the feasibility of an open surgical technique that allows removing stations 10 together with 11p and 11d with spleen and splenic vessels preservation in pacients operated upon by open surgery. Material and Methods: We present an open "Ex-situ" spleen and pancreas preserving surgical technique that removes the anterior and posterior ganglia from the splenic hilum, the splenic vessels and the distal pancreas in locally advanced gastric cancer cases of the upper two thirds of the stomach. Forty-three consecutive patients since 2003 were operated upon by the author in multiple centers. during upper two thirds gastric cancer resections requiring no. 10 lymphadenectomy. Results: no splenectomy was needed . All the spleens were viable at postoperative Doppler echography and CT scans. No spleen migrated nor caused mechanical complications. No clinically significant pancreatic leaks were noticed. Two patients died during hospital stay, one of miocardial infarction and one of massive stroke. Pertinent follow up data and survival were not available. Conclusions: The method enables the surgeon to remove the lymph nodes no. 10 along with 11p and 11d without needing to sacrifice the spleen. All spleens were reattached sucessfully using the preserved spleno-renal ligament fold, no wandering spleen was noticed.

Lumbar Melanoma with Sentinel Lymph Nodes in Multiple Basins - Case Report and Review of the Literature.

Intreduction: Melanoma is an extremely aggressive form of skin neoplasia, an important stage in the diagnostic and treatment is identifying the dissemination at the lymphatic level. For a more accurate staging, the sentinel lymph node biopsy technique is performed, which in most of the time addresses one, respectively 2 locations, but cases with sentinel nodes in 3 lymphatic basins have rarely been described. Case report: We present a case of melanoma located in the right lumbar region, which from the point of view of histopathological features has a Breslow index of 4.2 mm, classified in the pT4b stage. After the CT evaluation was performed, it was decided that there is indication for performing the sentinel lymph node technique and excision with a margin of safety. Scintigraphy revealed that sentinel lymph nodes were identified in 3 different regions, respectively the right axilla and bilateral inguinal. Conclusions: Melanoma located on the trunk can present different lymphatic routes for the sentinel lymph nodes, unlike that on the limbs where certain patterns are present. Identifying these lymph nodes in cases like this involves a challenge both from a diagnostic and surgical point of view.

Targeted axillary dissection reduces residual nodal disease in clinically node- positive breast cancer after neoadjuvant chemotherapy.

BACKGROUND: Any advantage of performing targeted axillary dissection (TAD) compared to sentinel lymph node (SLN) biopsy (SLNB) is under debate in clinically node-positive (cN+) patients diagnosed with breast cancer. Our objective was to assess the feasibility of the removal of the clipped node (RCN) with TAD or without imaging-guided localisation by SLNB to reduce the residual axillary disease in completion axillary lymph node dissection (cALND) in cN+ breast cancer. METHODS: A combined analysis of two prospective cohorts, including 253 patients who underwent SLNB with/without TAD and with/without ALND following NAC, was performed. Finally, 222 patients (cT1-3N1/ycN0M0) with a clipped lymph node that was radiologically visible were analyzed. RESULTS: Overall, the clipped node was successfully identified in 246 patients (97.2%) by imaging. Of 222 patients, the clipped lymph nodes were non-SLNs in 44 patients (19.8%). Of patients in cohort B (n=129) with TAD, the clipped node was successfully removed by preoperative image-guided localisation, or the clipped lymph node was removed as the SLN as detected on preoperative SPECT-CT. Among patients with ypSLN(+) (n=109), no significant difference was found in non-SLN positivity at cALND between patients with TAD and RCN (41.7% vs. 46.9%, p=0.581). In the subgroup with TAD with axillary lymph node dissection (ALND; n=60), however, patients with a lymph node (LN) ratio (LNR) less than 50% and one metastatic LN in the TAD specimen were found to have significantly decreased non-SLN positivity compared to others (27.6% vs. 54.8%, p=0.032, and 22.2% vs. 50%, p=0.046). CONCLUSIONS: TAD by imaging-guided localisation is feasible with excellent identification rates of the clipped node. This approach has also been found to reduce the additional non-SLN positivity rate to encourage omitting ALND in patients with a low metastatic burden undergoing TAD.

A phase III randomized clinical trial comparing laparoscopic radical hysterectomy based on open state with abdominal radical hysterectomy in patients with early-stage cervical cancer.

BACKGROUND: Cervical cancer is the fourth most frequently diagnosed cancer and the fourth leading cause of cancer death in women, The standard treatment recommendation for women with early cervical cancer is radical hysterectomy with pelvic lymph node dissection, however, articles published in recent years have concluded that the treatment outcome of laparoscopic surgery for cervical cancer is inferior to that of open surgery. Thus, we choose a surgically new approach; the laparoscopic cervical cancer surgery in the open state is compared with the traditional open cervical cancer surgery, and we hope that patients can still have a good tumor outcome and survival outcome. This trial will investigate the effectiveness of laparoscopic cervical cancer surgery in the open-state treatment of early-stage cervical cancer. METHOD AND DESIGN: This will be an open-label, 2-armed, randomized, phase-III single-center trial of comparing laparoscopic radical hysterectomy based on open state with abdominal radical hysterectomy in patients with early-stage cervical cancer. A total of 740 participants will be randomly assigned into 2 treatment arms in a 1:1 ratio. Clinical, laboratory, ultrasound, and radiology data will be collected at baseline, and then at the study assessments and procedures performed at baseline and 1 week, 6 weeks, and 3 months, and follow-up visits begin at 3 months following surgery and continue every 3 months thereafter for the first 2 years and every 6 months until year 4.5. The primary aim is the rate of disease-free survival at 4.5 years. The secondary aims include treatment-related morbidity, costs and cost-effectiveness, patterns of recurrence, quality of life, pelvic floor function, and overall survival. CONCLUSIONS: This prospective trial aims to show the equivalence of the laparoscopic cervical cancer surgery in the open state versus the transabdominal radical hysterectomy approach for patients with early-stage cervical cancer following a 2-phase protocol.

[Rethinking the scope of lymphadenectomy after neoadjuvant immunotherapy for locally advanced gastric cancer].

Radical gastrectomy is the core of comprehensive treatment for patients with locally advanced gastric cancer,while reasonable and standardized lymphadenectomy is the key to radical gastrectomy.With the continuous development of treatment methods and therapeutic drugs for advanced gastric cancer, it is worth exploring whether the scope of lymphadenectomy needs to be changed. Neoadjuvant immunotherapy has brought a new breakthrough for locally advanced gastric cancer, increased pathological complete response rate, reduced clinical stage of tumors, and increased radical surgical resection rate, but it has not brought long-term benefits to patients. Lymph nodes play an important role in human anti-tumor immune response, and some basic studies suggest that preserving some normal lymph nodes may be more helpful to enhance the efficacy of immunotherapy. Thus, in the era of immunotherapy, the extent of lymph node dissection for locally advanced gastric cancer needs to balance continuous drug benefits, patient quality of life, and survival benefits, awaiting further high-quality clinical research for determination. Questions such as how to differentiate between normal and metastatic lymph nodes, how to rationally preserve normal lymph nodes, and whether preserving partial lymph node function can lead to greater benefits for patients from immunotherapy warrant further exploration.

A retrospective analysis of lymph node dissection in Siewert II adenocarcinoma of the esophagogastric junction.

BACKGROUND: Analyze the pattern of lymph node metastasis in Siewert II adenocarcinoma of the esophagogastric junction (AEG) and provide a basis for the principles of surgical access. METHODS: The clinical data of 112 Siewert type II AEG patients admitted to the Fifth Department of Thoracic Surgery, the Fourth Hospital of Hebei Medical University from 2020 to 2022 were retrospectively collected. The probability of lymph node metastasis in each site and the clearance rate of lymph nodes in each site by different surgical approaches were analyzed. RESULTS: The lymph node metastasis rates in the middle and upper mediastinum group, the lower mediastinum group, the upper perigastric + supra pancreatic group, and the lower perigastric + hepatoduodenal group were 0.0%, 5.4%, 61.6%, and 17.1%, (P < 0.001). The number of lymph nodes cleared in the middle and upper mediastinum group was 0.00, 0.00, 4.00 in the transabdominal approach (TA), left thoracic approach (LT), and Ivor-Lewis (IL) group, (P < 0.001); The number of lymph nodes cleared in the lower mediastinal group was 0.00, 2.00, 2.00, (P < 0.001); The number of lymph node dissection in the perigastric + hepatoduodenal group was 3.00, 0.00, and 8.00, (P < 0.001). The overall complication rates were 25.7%, 12.5%, and 36.4%, (P = 0.058). CONCLUSION: Siewert II AEG has the highest rate of lymph node metastasis in the upper perigastric + supra-pancreatic region, followed by the lower perigastric + hepatoduodenal, lower mediastinal, middle, and upper mediastinal regions. Ivor-Lewis can be used for both thoracic and abdominal lymph node dissection and does not increase the incidence of postoperative complications.

Robot-assisted minimally invasive oesophagectomy versus thoracoscopic approach: multi-institutional study on short-term outcomes.

BACKGROUND: Robot-assisted minimally invasive oesophagectomy and conventional minimally invasive oesophagectomy are superior to open techniques. However, few studies have directly compared the outcomes of the two minimally invasive approaches. METHODS: A retrospective study of patients from six medical centres with oesophageal squamous cell carcinoma who underwent minimally invasive oesophagectomy between 2015 and 2022. Perioperative outcomes were compared after applying inverse probability of treatment weighting. RESULTS: The study included 577 patients (robot-assisted minimally invasive oesophagectomy: 206; conventional minimally invasive oesophagectomy: 371). After applying inverse probability of treatment weighting, robot-assisted minimally invasive oesophagectomy was found to yield a higher number of mediastinal nodes compared with conventional minimally invasive oesophagectomy (14.86 versus 12.66, P = 0.017). Robot-assisted minimally invasive oesophagectomy was notably effective in retrieving upper mediastinal left recurrent laryngeal nerve nodes, averaging 1.97 nodes versus 1.14 nodes harvested by conventional minimally invasive oesophagectomy (P < 0.001). This was coupled by a significant decrease in nerve palsy rates (13.9% versus 22.8%, P = 0.020). A significantly larger percentage of patients in the robot-assisted minimally invasive oesophagectomy group had an uncomplicated postoperative course (51.8% versus 34%, P < 0.001). Robot-assisted minimally invasive oesophagectomy also led to a reduction in pneumonia rates (8.6% versus 15.2%, P = 0.041) and was linked to a shorter length of stay (length of stay; 16.64 versus 21.14 days, P = 0.007). The advantage of robot-assisted minimally invasive oesophagectomy in reducing the length of stay was especially pronounced in patients with a high Charlson co-morbidity index (≥2, mean difference 8.46 days; P = 0.0069) and those who underwent neoadjuvant therapy (mean difference 5.63 days; P < 0.001). CONCLUSION: In oesophageal squamous cell carcinoma, the use of robot-assisted minimally invasive oesophagectomy led to fewer cases of pneumonia and faster recovery compared with conventional minimally invasive oesophagectomy. Additionally, robot-assisted minimally invasive oesophagectomy significantly improved the feasibility and safety of performing lymph node dissection along the recurrent laryngeal nerve.

Complications and adverse events in lymphadenectomy of the inguinal area: worldwide expert consensus.

BACKGROUND: Inguinal lymph node dissection plays an important role in the management of melanoma, penile and vulval cancer. Inguinal lymph node dissection is associated with various intraoperative and postoperative complications with significant heterogeneity in classification and reporting. This lack of standardization challenges efforts to study and report inguinal lymph node dissection outcomes. The aim of this study was to devise a system to standardize the classification and reporting of inguinal lymph node dissection perioperative complications by creating a worldwide collaborative, the complications and adverse events in lymphadenectomy of the inguinal area (CALI) group. METHODS: A modified 3-round Delphi consensus approach surveyed a worldwide group of experts in inguinal lymph node dissection for melanoma, penile and vulval cancer. The group of experts included general surgeons, urologists and oncologists (gynaecological and surgical). The survey assessed expert agreement on inguinal lymph node dissection perioperative complications. Panel interrater agreement and consistency were assessed as the overall percentage agreement and Cronbach's α. RESULTS: Forty-seven experienced consultants were enrolled: 26 (55.3%) urologists, 11 (23.4%) surgical oncologists, 6 (12.8%) general surgeons and 4 (8.5%) gynaecology oncologists. Based on their expertise, 31 (66%), 10 (21.3%) and 22 (46.8%) of the participants treat penile cancer, vulval cancer and melanoma using inguinal lymph node dissection respectively; 89.4% (42 of 47) agreed with the definitions and inclusion as part of the inguinal lymph node dissection intraoperative complication group, while 93.6% (44 of 47) agreed that postoperative complications should be subclassified into five macrocategories. Unanimous agreement (100%, 37 of 37) was achieved with the final standardized classification system for reporting inguinal lymph node dissection complications in melanoma, vulval cancer and penile cancer. CONCLUSION: The complications and adverse events in lymphadenectomy of the inguinal area classification system has been developed as a tool to standardize the assessment and reporting of complications during inguinal lymph node dissection for the treatment of melanoma, vulval and penile cancer.

[D2 and D3 lymph node dissection for colon cancer]. / Rezul'taty limfodissektsii d2 i d3 pri rake obodochnoi kishki.

OBJECTIVE: To evaluate surgical and oncological results of standard and extended lymph node dissection (D2 and D3) in patients with colon cancer. MATERIAL AND METHODS: We analyzed treatment outcomes in 74 patients with colon cancer stage T1-4aN0-2M0 who underwent right- and left-sided hemicolectomy, resection of sigmoid colon with standard and extended lymph node dissection (D2 and D3). RESULTS: Surgical approach and level of D3 lymph node dissection did not increase intra- and postoperative morbidity. Laparoscopic interventions were followed by significantly lower intraoperative blood loss and earlier gas discharge. Metastatic lesion of apical lymph nodes was observed in 5 out of 36 patients who underwent D3 lymph node dissection (13.8%), and metastases in regional lymph nodes rN1-2 were found in all these patients. Overall 5-year survival was 86%. Disease-free and overall 5-year survival were similar after D2 and D3 lymph node dissection. CONCLUSION: D3 lymph node dissection is safe for colon cancer. Metastatic lesions of apical lymph nodes during D3 lymph node dissection were detected only in patients with lesions of regional lymph nodes (rN1-2). Disease-free and overall 5-year survival were similar after D2 and D3 lymph node dissection.

[Own experience of indocyanine green use in the diagnosis and treatment of breast cancer in N.N. Petrov NMRC of Oncology]. / Sobstvennyi opyt ispol'zovaniya indotsianina zelenogo v diagnostike i lechenii raka molochnoi zhelezy v NMITs onkologii im. N.N. Petrova.

OBJECTIVE: To evaluate the possibility of using the method of sentinel lymph nodes (SLN) detection with indocyanine green (ICG) in patients with early breast cancer and its informativeness. MATERIAL AND METHODS: A «Determination of sentinel lymph nodes by fluorescence method intraoperatively with the use of indocyanine green¼ study, in which 168 patients are currently included, is being conducted in the clinic of the N.N. Petrov NMRC of Oncology from 2017 through the present. All patients who underwent biopsy of sentinel lymph nodes (BSLN) were primary with a T1-2N0M0 stage of process. RESULTS: The average number of axillary lymph nodes removed in BSLN was 3 (1-5). Accumulation of ICG was found in 147 (88%) patients, accumulation of labeled radiocolloid - in 137 (82%), in combination of ICG/radiocolloid - in 167 (99%) based on the results of imaging. CONCLUSION: The obtained results prove that the informativeness and relative simplicity of this method use allow its application in any hospital where breast cancer is surgically treated, as well as in the absence of radioisotopic equipment.
