Sentinel lymph node biopsy for early stage tongue cancer—a 14-year single-centre experience

This study was performed to report the usage of sentinel lymph node biopsy (SLNB) in clinical stage I or II tongue cancer patients with cN0 necks seen over a 14-year period. Data were collected prospectively, and a retrospective analysis was performed of 41 patients with early stage oral squamous cell carcinoma of the tongue and a cN0 neck. Sentinel lymph node (SLN)-positive patients underwent elective neck dissection, whereas SLN-negative patients were kept under careful observation. Seven of the 41 (17%) patients enrolled in the study were found to have occult metastases. The patients were followed up for a mean duration of 92 months (range 60–144 months). The neck recurrence rate for SLN-positive patients was 0% and for SLN-negative patients was 3%. The authors recommend the routine use of SLNB in patients with early stage oral squamous cell carcinoma of the tongue and a cN0 neck. Furthermore, special focus should be placed on isolated tumour cells, as their presence is of high clinical relevance.     

Current thinking in management of the neck (including contralateral neck) in ipsilateral recurrent or second primary oral squamous cell carcinoma

Metastasis to the neck in patients with oral squamous cell carcinoma (SCC) has a huge impact on long-term survival and prognosis, and its incidence varies. Due consideration therefore should be given to management of the neck in each individual case. The pathways in patients with primary oral SCC are well-established, but there is a paucity of published papers on management of the neck in those with ipsilateral recurrent or second primary oral SCC whose necks have previously been operated on with or without radiotherapy or chemoradiotherapy, or treated with radiotherapy or chemoradiotherapy alone. These patients may be under treated because of failure to stage the most likely drainage site, and are likely to have a worse outcome if there is macroscopic recurrence in the neck after independent treatment of the recurrent or second primary tumour. Based on the current review, we think there is a need for a multicentre, collaborative, retrospective review of the outcomes of patients with ipsilateral second primaries or recurrent oral SCC in the previously treated neck. Our recommendations include consideration of positron emission tomography-computed tomography in all patients with recurrent or second primary oral SCC (if “hot” – neck dissection, if “cold” - sentinel node biopsy); consideration of sentinel node biopsy in all patients with recurrent or second primary oral SCC who have previously had treatment to the neck; and finally, consideration of definitive management of the sentinel biopsy zone or region if the node is invaded.     

Echocardiographic features of interventricular septal dissection in patients with Behçet's disease

Involvement of the heart in Behçet's disease (BD) is rare. We retrospectively analyzed these three patients with interventricular septal (IVS) dissection in BD and discussed the echocardiographic manifestations of IVS dissections. In our patients, the echocardiographic characteristics of IVS dissection were echo‐free space in the IVS basal segment or basal to middle segment, dilatation in the diastole and contraction in systole, and abnormal turbulent blood flow in the heart.

A Novel Nomogram to Identify Candidates for Extended Pelvic Lymph Node Dissection Among Patients with Clinically Localized Prostate Cancer Diagnosed with Magnetic Resonance Imaging-targeted and Systematic Biopsies

Background

Available models for predicting lymph node invasion (LNI) in prostate cancer (PCa) patients undergoing radical prostatectomy (RP) might not be applicable to men diagnosed via magnetic resonance imaging (MRI)-targeted biopsies.

The critical role of lymph node dissection in selecting high-risk nonmetastatic renal cancer candidates for adjuvant therapy after nephrectomy

Background

The role of lymph node dissection (LND) during nephrectomy for renal cell carcinoma (RCC) is controversial. We looked at the clinical usefulness of performing LND to stratify the risk of patients with RCC and select candidates for systemic treatment after nephrectomy.

Near-infrared fluorescence imaging improves the nodal yield in neck dissection in oral cavity cancer – A randomized study

IntroductionLymph node yield (LNY) in neck dissection has been identified as a prognostic factor in oral cavity cancer. The purpose of this study was to investigate the impact of additional use of optical imaging on LNY in therapeutic ND in oral cancer.MethodsConsecutive patients with oral squamous cell carcinoma with clinical neck metastasis planned for primary tumor resection were randomized to conventional neck dissection or near-infrared fluorescence (NIRF)-guided neck dissection, respectively. In the intervention group, patients were injected with ICG-Nanocoll prior to surgery. Intraoperatively, an optical hand-held camera system was used for lymph node identification. Also, NIRF imaging of the neck specimen was performed, and optical signals were pinned with needle markings to guide the pathological examination. The endpoint of the study was LNY per neck side in levels Ib-III.Results31 patients were included with 18 neck sides in the control group and 18 neck sides in the intervention group for evaluation. During NIRF-guided ND, individual lymph nodes could be identified by a bright fluorescent signal and individual tumor-related drainage patterns could be observed in the neck. The LNY in the intervention group was significantly higher compared to the control group (p = 0.032) with a mean of 24 LN (range: 12–33 LN in levels Ib-III compared to 18 LN (range: 10–36 LN) in the control group, respectively.ConclusionsNIRF-guided ND significantly improved the nodal yield compared to the control group. Intraoperative real-time optical imaging enabled direct visualization of tumor-related drainage patterns within the neck lymphatics.     

Voice outcome indicators for unilateral vocal fold paralysis surgery: A survey among surgeons

IntroductionStandardization of voice outcomes indicators (VOIs) is an important issue when it comes to evaluating and comparing surgical treatments for Unilateral Vocal Fold Paralysis (UVFP). In a recent review, 11 VOIs were found to represent 80% of the VOIs cited in the literature. A survey was launched among the European laryngologists to acquire surgeons’ opinions on the above mentioned preselected VOIs.Material and methodThe electronic survey took place between November and December 2016. Three general questions were asked about surgeon's practice setting(s) and experience. The eleven next questions concerned (a) surgeon's VOIs preference and (b) their estimates of post-operative target values, they would consider being satisfactory.ResultsThe response rate was 16% (50 surveys). The majority of responders worked in tertiary hospitals (50%), had 15 years of experience with UVFP and performed on average 20 UVFP related procedures a year. The VOIs that were favored by the responding surgeons were, in decreasing order of importance, Voice handicap Index (VHI-30), Maximum Phonation Time (MPT), GRBAS-I, Mean Airflow Rate (MeAF), Jitter and Shimmer. There was an excellent consensus on post-operative VOI target values between survey's results and the literature data, except for three VOIs that showed somewhat divergent tendencies (absolute VHI-30, Jitter and Shimmer).ConclusionsThree VOIs are favored by surgeons: VHI-30, MPT and GRBAS-I. Jitter and Shimmer, although very frequently reported and statistically valid in the literature, come last concerning surgeon's choice as VOI for UVFP treatment assessment.
