This study aimed to assess the accuracy of predicting pelvic lymph node status using sentinel lymph node (SLN) biopsy with indocyanine green (ICG) and to examine the outcomes of SLN biopsy-guided abdominal radical trachelectomy (ART). Patients with stage IA2–IB2 cervical cancer from January 2009 to January 2021 were included. ICG was injected before ART and SLNs were identified, excised, and assessed intraoperatively using fast-frozen sections. Systemic pelvic lymphadenectomy was subsequently performed. The SLN detection rate, sensitivity, and false-negative rate were determined. Thirty patients desiring fertility preservation were enrolled, of whom 26 successfully completed ART and four underwent radical hysterectomies because of metastatic primary SLNs. Bilateral SLNs were identified in all patients. The sensitivity, false-negative rate, and negative predictive value were 100%, 7.7%, and 92.3%, respectively. Three (12%) patients were lost to follow-up: two relapsed and one died of tumor progression. Of the nine patients who tried to conceive after surgery, four achieved pregnancy and three delivered healthy live infants. In women with early-stage cervical cancer who desired to conserve fertility, SLN mapping with ICG had a very high detection rate, sensitivity, and low false-negative rate. SLN biopsy-guided ART is a feasible and accurate method for assessing pelvic node status.

Purpose To determine the detection rate, the false-negative rate, and the accuracy of sentinel lymph node (SLN) detection after neoadjuvant chemotherapy (NAC) for advanced breast cancer. Patients and Methods A prospective multicentric study was initiated to evaluate the results of SLN biopsy with the combined method after NAC for advanced large operable breast cancer. Results From September 2003 to March 2007, 195 patients enrolled from 12 institutions were found suitable for evaluation. The detection rate was 90% (176 of 195 patients), and the false-negative rate was 11.5% (six of 52 patients). Patients without axillary palpable nodes (N0) before NAC had a better detection rate compared with patients with axillary suspicious nodes (N1, 94.6% v 81.5%; P = .008). The false-negative rate was not correlated with clinical nodal status before NAC (9.4% v 15%; P = .66). Conclusion This study confirms the feasibility of SLN biopsy after NAC in the case of large operable breast cancer. The detection rate, false-negative rate, and accuracy do not differ from those obtained in the case of early breast cancer without NAC, thus demonstrating the feasibility of SLN biopsy after NAC.

Abstract Introduction and Aims The aim of this systematic review is to provide an up-to-date evaluation of the role and test performance of sentinel lymph node biopsy (SLNB) in the head and neck. Method This review follows the PRISMA guidelines. Database searches for MEDLINE and EMBASE were constructed to retrieve human studies published between 1st January 2010 and 1st July 2020 assessing the role and accuracy of sentinel lymph node biopsy in cutaneous malignant melanoma of the head and neck. Articles were independently screened by two reviewers and critically appraised using the MINORS criteria. The primary outcomes consisted of the sentinel node identification rate and test-performance measures, including the false-negative rate and the posttest probability negative. Results A total of 27 studies, including 4688 patients, met the eligibility criteria. Statistical analysis produced weighted summary estimates for the sentinel node identification rate of 97.3% (95% CI, 95.9% to 98.6%), the false-negative rate of 21.3% (95% CI, 17.0% to 25.4%) and the posttest probability negative of 4.8% (95% CI, 3.9% to 5.8%). Discussion Sentinel lymph node biopsy is accurate and feasible in the head and neck. Despite technical improvements in localisation techniques, the false negative rate remains disproportionately higher than for melanoma in other anatomical sites.

INTRODUCTION: Introduction: Sentinel lymph node biopsy (SLNB) is now recognized as the standard of care for early breast cancer patients with negative axillary lymph nodes. Various approaches for Sentinel Lymph Node (SLN) identification using either the blue dye method or scintigraphy alone or their combination have been proposed. However, this method is costly and may not be applicable in certain developing countries. SLNB involving the use of indocyanine green (ICG) offers several advantages, and it is valid and safe when in direct comparison with the blue dye method and scintigraphy. Hence, we performed SLNB using this method in early breast cancer as the first center that involves the use of ICG in Malaysia. We performed validation study on this method with the aims to determine its sensitivity and safety profile. MATERIALS AND METHODS: This is a validation and non-randomised prospective observational study involving 20 patients underwent SLNB wherein ICG is used for localisation. The patients were recruited according to the recommendations stipulated in the Malaysia Clinical Practice Guideline. RESULT: The average number of SLNs removed per patient was 4.0 (range, 3–6) with sentinel lymph nodes detection rate at 98.75% (79/80). The false negative rate is at 5%. No adverse events were observed in all cases. CONCLUSION: The ICG fluorescence method is simple, reliable and safe. Moreover, it demonstrates a high SLN detection rate with a low false-negative rate, and it does not require a special instrument for radioisotope use.

Abstract Background Sentinel lymph node biopsy (SLNB) acts as a vital role in the breast cancer surgery, and the identified number of sentinel nodes determines its accuracy to represent the status of axillae. There remain two tumor biopsy modes in breast cancer, preoperative and intraoperative biopsy. We compared the effect of the two different biopsies on the result of SLNB. Methods Patients with clinical stage T1-3, N0 tumor were enrolled in this study. 53% received preoperative tumor biopsy and 47% received intraoperative excisional biopsy. For search of the sentinel lymph node, patients received dual tracer injection. The number of SLNs detected and false negative rate were compared between groups. Results 204 patients were enrolled, 108 received preoperative tumor biopsy and 96 received intraoperative excisional biopsy. Among all the patients, 160 received ALND following SLNB. Preoperative tumor biopsy detected more SLNs than intraoperative biopsy (mean rank 113.87 vs. 90.9, p= 0.004). False negative rate in preoperative and intraoperative tumor biopsy was 3% and 18%, respectively. Conclusions Patients in preoperative tumor biopsy group could find more SLNs than intraoperative biopsy patients. False negative rate was also lower in preoperative biopsy group.
