ObjectivesTo characterize our institutional experience with sentinel lymph node (SLN) biopsy in patients with vulvar cancer. We describe the oncologic outcomes of these patients and the utilization of SLN detection techniques over time.MethodsA retrospective analysis of all patients who underwent inguinofemoral SLN biopsy as part of their treatment for vulvar cancer at Memorial Sloan Kettering Cancer Center from January 1, 2000 to April 1, 2019. Patients were included in this analysis if they underwent inguinofemoral SLN biopsy for vulvar cancer, irrespective of presenting factors such as histology, tumor size or laterality. An “at-risk groin” was defined as either the right or left groin for which SLN biopsy of inguinofemoral lymph nodes was performed.ResultsA total of 160 patients were included in our analysis, representing 265 at-risk groins. 114 patients had squamous cell histology representing 195 at-risk groins. Of the 169 negative groins in patients with squamous cell carcinoma, the 2 year isolated groin recurrence rate was 1.2%. SLN detection rate, irrespective of modality, was 96.2%. Technetium-99 (TC-99) + blue dye detected SLNs in 91.8% of groins; TC-99 + indocyanine green detected SLNs in 100% of groins (p=0.157). Among the 110 groins that underwent mapping with TC-99 and blue dye, 4 patients had failed mapping with blue dye and mapped with TC-99 alone (3.6%). Among the 96 groins that underwent mapping with TC-99 and ICG, 14 patients failed to map with TC-99 and mapped with indocyanine green alone (14.6%).ConclusionsSLN mapping in vulvar cancer is reliable and oncologically effective. The utilization of indocyanine green for mapping has increased over the past decade and is associated with high rates of SLN detection.

Abstract Background Vulvar cancer is a rare gynecological malignancy that primarily affects women of postmenopausal age. Treatment is mainly surgical, particularly for vulvar squamous cell carcinoma, the most prevalent histotype. In patients with unifocal tumors with a maximum diameter of <4 cm, in the absence of suspected inguinal lymph nodes, sentinel lymph node (SLN) biopsy is recommended. The use of a radioactive tracer is mandatory; the use of the vital blue dye is optional. Results Two patients diagnosed with vulvar squamous cell carcinoma (FIGO IB stage) underwent bilateral radical vulvectomy, SLN search and removal, and bilateral inguinal lymphadenectomy at the Cannizzaro Hospital Operative Unit of Obstetrics and Gynecology Department (Catania, Italy). Three milliliters of indocyanine green (ICG) 0.5 mg/mL was administered in 3 peritumoral injections under general anesthesia to screen the SLN. The images were acquired using an intraoperative infrared camera system, which allowed intraoperative visualization of the SLN. An SLN was identified for each patient. The lymph nodes examined by the pathologist were negative for metastatic localization of the disease. However, patients underwent bilateral inguinofemoral lymphadenectomy, as this procedure is not currently codified as a gold standard for the detection of SLN in vulvar cancer. All the lymph nodes removed were negative for the localization of vulvar carcinoma metastases. Conclusions The potential of the administration of indocyanine green (ICG) allows the execution of SLN biopsy, avoiding the multiple administrations of radiocolloid in the pre-operative phase, painful for the patient, elimination, and exposure to radioactivity. Therefore, while requiring standardization of the methodology and a large-scale application, this procedure could open a new surgical management perspective in patients with early-stage vulvar cancer.

Reducing false negative rates for sentinel lymph node biopsies (SLNB) in melanoma is important to accurately prognosticate and to guide treatment. Traditionally, SLNB has been performed with the adjunct of radiotracers and blue dye. Although sentinel node mapping is highly successful in axillary and inguinal node basins, identification of nodes in the head and neck is not as accurate with traditional methods. One reason for this may be failure of radiotracer migration. To augment standard technique using a radiocolloid, indocyanine green (ICG) combined with near infrared spectroscopy (NIRS), has shown promising results. We demonstrate a case of an individual undergoing SLNB in the head and neck region with failure of radiotracer migration. Identification of a sentinel node was accomplished with the use of ICG and NIRS. This technology offers an opportunity to salvage the SLNB when traditional methods fail.

ObjectiveSentinel lymph node (SLN) mapping is increasingly being used in the treatment of apparent early-stage endometrial cancer. The aim of this study was to evaluate whether three tracers (blue dye, indocyanine green (ICG), and technetium-99 (Tc99)) performed better than two (ICG and Tc99).Study DesignProspective study of all consecutive patients (n=163) diagnosed with clinical early-stage endometrial cancer from 2015 to 2017. All patients were randomly assigned to receive a mixture of ICG and Tc99 with or without blue dye. Subgroup analysis for detection rates was performed for each group (double versus triple tracer).ResultsOne hundred and fifty-seven patients met the inclusion criteria. Eighty patients received ICG and Tc99 with unilateral and bilateral SLN detection rates of 97.5% and 81.3%, respectively. Seventy-seven patients received all three tracers with unilateral and bilateral detection rates of 93.5% and 80.5%, respectively. Only one patient in the triple tracer group was detected by blue dye alone. No significant differences were noticed in unilateral or bilateral detection rates between the two groups, nor in the detection of lymph node metastasis.ConclusionThe addition of blue dye to ICG and Tc99 did not demonstrate any improvement in SLN detection.

Pelvic and para-aortic lymphadenectomy is routinely performed in early ovarian cancer to define the stage of the disease. However, it may be associated with increased blood loss, operative time, and length of hospitalization. The sentinel lymph node technique has been shown to be safe and feasible in vulvar, uterine, and cervical cancer. Data detailing feasibility and outcomes of sentinel lymph node mapping in ovarian cancer are scarce.To summarize the studies evaluating the feasibility of sentinel lymph node detection from the ovary, examining the technique and detection rate.A systematic search of the literature was performed using PubMed and Embase from June 1991 to February 2019. Studies describing the sentinel lymph node technique and lymphatic drainage of the ovaries were incorporated in this review. Ten articles were selected, comprising a total of 145 patients. A variety of agents were used, but the primary markers were technetium-99m radiocolloid (Tc-99m), patent blue, or indocyanine green, and the most common injection site was the ovarian ligaments.The overall sentinel lymph node detection rate was 90.3%.We propose a standardized technique sentinel lymph node mapping in ovarian cancer, using indocyanine green, or Tc-99m and blue dye as alternative tracers, injected in both the suspensory and the infundibulopelvic ligament of the ovary.

BACKGROUND: Sentinel lymph node (SNL) biopsy in breast cancer for the determination of axillary status is standard procedures in surgical treatment of early-stage breast cancer. The identification of the SNL is usually performed by radiocolloid injection or/and injection of methylene blue due. The use of indocyanine green (ICG) dye, which is fluorescent dye, which movement in breast and axillar pit, can be followed with special cameras which detect near infrared specatar of light. CASE REPORT: In this paper, we present case report of patient with breast cancer, where we perform SNL detection with three methods: Use of radiocolloid which we trace with static gamma camera, and intraoperatively with hand held gamma probe, methylene blue dye which movement we followed by eye contact and using indocyanine green which movement was followed by specially constructed multispectral camera, which can detect near-infrared fluorescence that is emitted by ICG and methyline blue, respectively. CONCLUSION: Fluorescent imaging with ICG is a sensitive, valuable, and safe method for SNL biopsy. Finding new agents that would identify the SNL, especially if they are not radioactive would be an important step in wider application of this method.
