Sentinel node studies in truncal melanoma: does an increased number of draining basins correlate with an increased risk of lymph metastasis?

Abstract Purpose Coregistered SPECT/CT can improve accuracy of sentinel node biopsy (SNB) for staging melanoma. This benefit has implications for pathology services and surgical practice with increased diagnostic and surgical workload. The purpose of this study was to investigate the effectiveness of SPECT/CT imaging. Methods SNB data were collected over a 10-year period. Preoperative SLN mapping was performed by using planar lymphoscintigraphy (LSG) for all patients (n = 1522) and after October 2015, patients underwent a second co-registered SPECT/CT scan (n = 559). The patients were stratified according to the imaging protocol. The number of nodes and nodal basins were assessed. The reasons for cancellation also were assessed. Results A total of 95% (1446/1522) of patients underwent a successful SNB procedure. Significantly more sentinel nodes were identified by the SPECT/CT protocol (3 vs. 2; p < 0.0001). More patients were cancelled in the SPECT/CT cohort (9.3% vs. 2.5%; p < 0.0001). Head & neck, lower limb, and AJCC IB primaries were significantly less likely to proceed to SNB. SPECT/CT identified significantly more positive SNBs (20.9% vs. 16.5%; p = 0.038). SPECT/CT imaging was associated with improved disease-free (hazard ratio [HR] = 0.74; 95% confidence interval [CI]: 0.54–1.0); p = 0.048) and disease-specific survival (HR = 0.48; 95% CI: 0.3–0.78; p = 0.003). Patients who did not proceed to SNB had a significantly increased nodal relapse rate (23.5% vs. 6.8%; HR = 3.4; 95% CI: 1.9–6.2; p < 0.0001) compared with those who underwent SNB. Conclusions This large cohort study confirms the increased accuracy of SPECT/CT for identifying SLN metastases, which would appear to have a significant therapeutic benefit, although an increased risk of cancellation of the SNB procedure on the day of surgery.

1024 Background: Ductal lavage (DL) is designed to obtain cellular material from breast ducts. The use of DL in risk assessment is under investigation. The aim of this study was to evaluate cytologic findings in DL of affected and unaffected breasts in women undergoing definitive surgery for breast cancer. Methods: Women with newly diagnosed breast cancer participated prior to surgery. Women with prior breast cancer or receiving neoadjuvant therapy were excluded. The study was IRB approved; all women gave written informed consent. Women underwent nipple aspiration followed by ductal lavage of fluid-producing ducts for both the affected and unaffected breast in the operating room prior to surgery. Cytology was interpreted as insufficient cells to make a diagnosis (ICMD), benign, mildly or markedly atypical, or malignant. Results: Twenty-three women aged 32–74 years underwent nipple aspiration of both breasts prior to definitive surgery; 1 had bilateral breast cancer. One woman had DCIS, 1 T1a, 3 T1b, 9 T1c, 6 T2, and 4 T3 lesions. Node status was N0 in 13, N1mic in 3, N1 in 5 and N2 in 3 (15 underwent sentinel node evaluation). Five women produced no NAF and therefore did not undergo DL; 18 underwent DL of at least one breast. Cytology samples were available for 30 breasts, 16 affected and 14 unaffected. Two samples contained malignant cells (one from a patient with pre-existing malignant nipple discharge), 3 moderate atypia, all from affected breasts. Benign cytology was found in 20 samples (8 affected breasts) and ICMD was classified in 5 samples (3 affected breasts). Age (</> 50), tumor size, nodal status, or sentinel node procedure were not associated with NAF production, success or cytology of DL. Conclusion: These findings suggest that DL is not effective in identifying known breast cancer. It brings into question its ability to identify women at increased risk. Future research should focus on molecular markers of risk or other means of tissue retrieval. No significant financial relationships to disclose.

Increased Risk

Abstract Background Since the introduction of sentinel node biopsy (SLNB) in unifocal vulvar cancer (diameter of < 4 cm) and unsuspicious groin lymph nodes, the morbidity rate of patients has significantly decreased globally. In contrast to SLNB, bilateral inguinofemoral lymphadenectomy (IFL) has been associated with increased risk of common morbidities. Current guidelines (NCCN, ESGO, RCOG, and German) recommend that in cases of unilaterally positive sentinel lymph node (SLN), bilateral IFL should be performed. However, two recent publications by Woelber et al. and Nica et al. contradict the current guideline, since a significant rate of positive non sentinel lymph nodes in IFL contralaterally was not observed [Woelber et al. 0% (p = 0/28) and Nica et al. 5.3% (p = 1/19)]. Methods A retrospective single-center analysis conducted in the University Hospital of Dusseldorf, evaluating vulvar cancer patients treated with SLNB from 2002 to 2018. Results 22.2% of women (n = 4/18) were found to have contralateral IFL groin metastasis after an initial diagnosis of unilateral SLN metastasis. The depth of tumor infiltrating cells correlated significantly and positively with the rate of incidence of groin metastasis (p = 0.0038). Conclusion Current guideline for bilateral IFL should remain as the standard management. Therefore, this depth may be taken into account as an indication for bilateral IFL. The management of VC and SLNB should be performed in a high volume center with an experienced team in marking SLN and performing the adequate surgical procedure. Well conducted counseling of the patients outlining advantages but also potential oncological risks of this technique especially concerning rate of groin recurrence is critical.
