Survival in node-positive early oral squamous cell carcinoma: sentinel node biopsy versus elective neck dissection

Patients undergoing sentinel node biopsy (SLNB) for early oral squamous cell carcinoma (OSCC) who harbour occult metastases (pN+ve) may be at greater risk of mortality due to prolonged overall treatment times than those identified as pN+ve on elective neck dissection (ELND). A retrospective comparative survival analysis was therefore undertaken to test this hypothesis. Patients were identified from the South Glasgow multidisciplinary team (MDT) database. Group 1 comprised 38 patients identified as pN+ve, or who were false negative, on sentinel lymph node biopsy (SLNB). Group 2 comprised 146 patients staged pN+ve on ELND. The groups were compared with the Kaplan Meier method and Cox proportional hazards model. In addition, a matched-pair analysis was performed. A unique and specifically designed algorithm was deployed to optimise the pairings. No difference in disease-specific or overall survival was found between the groups. Patients undergoing SLNB as the initial neck staging modality in early OSCC and are identified as pN+ve do not appear to be at a survival disadvantage compared with those staged with ELND.

Sentinel lymph node biopsy with preoperative CT lymphography and intraoperative indocyanine green fluorescence imaging for N0 early tongue cancer: A long-term follow-up study

PurposeThis study evaluated the usefulness of sentinel lymph node (SLN) biopsy with preoperative computed tomographic lymphography (CTL) and intraoperative indocyanine green (ICG) fluorescence imaging for N0 early tongue cancer.MethodsTwenty-seven patients with N0 early oral tongue cancer underwent CTL with a 128-slice multi-detector row CT scanner to detect SLN on the day before resection of primary tumor and SLN biopsy under ICG fluorescence guidance. We identified the location and number of SLNs mapped by CTL and evaluated whether CTL-enhanced SLNs could be identified intraoperatively as ICG fluorescent lymph nodes. Prognosis was also evaluated.ResultsSLNs were detected by CTL in 26 of 27 patients (96.3%). The total and mean numbers of SLNs were 41 and 1.5, respectively. All SLNs enhanced by CTL could be identified intraoperatively as ICG fluorescent lymph nodes. Two SLNs were found under ICG fluorescent guidance in only one patient without SLN enhanced by CTL. Among the 27 patients, five (18.5%) had SLN with metastasis. Median follow-up was 76 months (range 44–82 months). During follow-up, three of 22 patients without SLN metastasis had occult cervical lymph node metastasis. The 5-year overall survival rate was 100%.ConclusionSLN biopsy with preoperative CTL and intraoperative ICG fluorescence imaging is a feasible and reliable procedure, without radioisotope tracers, for neck management in cases of early tongue cancer.

Challenges and outcomes in establishing a sentinel lymph node biopsy service for oral squamous cell carcinoma in a regional district specialist hospital

UK national guidelines in 2016 recommended that sentinel lymph node biopsy (SLNB) should be offered to patients with early oral squamous cell carcinoma (OSCC). We review the establishment of an OSCC SLNB service with specific consideration to resources, service implications and patient outcomes. A review of processes was performed to identify key stages in establishing the service, and subsequently a retrospective cohort study consisting of 46 consecutive patients with T1/T2 N0 OSCC was undertaken. The key stages identified were: coordinating a nuclear medicine pathway and reliable cost-appropriate pathology service, constructing a Trust business case, and gaining approval of a new interventional service policy. A median (range) of 3.3 (1-8) sentinel nodes (SLN) were removed, with 17 patients having a positive SLN. The negative predictive value of SLNB was 100%, with 12 having a SLN outside the field if elective neck dissection (END) was planned. There was a significantly increased risk of a positive SLN with increasing depth of invasion (DOI) (p=0.007) and increased diameter (p=0.036). We also identified a longer-than-ideal time to completion neck dissection and inadequate ultrasound follow up of negative SLNB patients. Establishment of a service requires careful planning. Our results were in keeping with those reported in the literature, and showed that SLNB for OSCC has a high negative predictive value and can identify at-risk SLN outside the traditional END levels, even in well-lateralised tumours. Our findings show that DOI and size of SLN were significantly associated with a positive SLN, and also identified areas requiring improvement.

The value of histological grading of biopsy and resection specimens in early stage oral squamous cell carcinomas

Introduction

In oral squamous cell carcinoma (OSCC) the differentiation grade of the tumor is determined on the biopsy and the resection specimen. The relation between tumor grade, nodal metastasis and survival is debatable. The aims of this study were to determine the correlation between differentiation grade of the biopsy and the resection specimen. Furthermore, we wanted to correlate tumor differentiation grade with nodal stage and survival.
