Circulating Hybrid Cells as a Marker of Nodal Metastases in Oral Cavity Squamous Cell Carcinoma

The current standard of care for clinically N0 patients at risk for cervical lymph node metastases is to undergo neck dissection for completion of staging, as the status of the cervical lymph node basins at the time of diagnosis provides important information about prognosis and treatment planning. However, up to 70% of cN0 patients have no nodal disease and thus underwent unnecessary surgery. The aim of this study is to identify an easily available peripheral blood biomarker that could serve as a marker of occult nodal metastases in cN0 patient with oral cavity squamous cell carcinoma (OCSSCa).

Authors: Asai S, Fukaya M, Fujieda H, Igami T, Tsunoda N, Sakatoku Y, Kamei Y, Miyata K, Nagino M Abstract A 71-year-old woman with dysphagia was diagnosed with thoracic esophageal squamous cell carcinoma by endoscopic biopsy at another hospital. She had previously undergone partial breast excision with axillary lymph node dissection for right breast cancer eleven years earlier and subtotal stomach-preserving pancreatoduodenectomy with Child's reconstruction for ampullary cancer ten years earlier. Gastrointestinal endoscopy showed a stricture due to a bulging submucosal tumor in the mid-thoracic esophagus. The tumo...

YuAbstractOur purpose was to provide a pathological basis for preservation of the submandibular glands during neck dissection for oral squamous cell carcinoma (SCC) by investigating whether intraglandular lymph nodes exist in submandibular glands, and the modes of involvement of submandibular glands in oral SCC. We studied the records of 95 patients with oral SCC (other than that in the floor of the mouth) treated at our hospital from January 2017 to June 2018. The specimen...

ConclusionsMHSCC seems to show a better overall survival compared to OSCC of other locations and is less likely to develop regional and distant metastasis; END might not be necessary in early stage tumors.

DiscussionWith a look to the possibility of a 5-year survival in patients with a N+ status in level IV and V, the justification for a radical approach to the neck appears questionable. However, modified radical neck dissection appears to be a suitable for a high-risk oral cancer subgroup. A randomised controlled trial is needed to define guidelines for the neck dissection extent in c/pN + cases.

ZhangAbstractWe have explored the relations between clinicopathological features and cervical lymph node metastases (LNM) in patients with cN0 squamous cell carcinoma (SCC) of the tongue, and developed and validated a nomogram for predicting the risk of their development. Clinical data on 230 patients with cN0 SCC of the tongue who had had primary extended excision and lymph node dissection of the neck were collected retrospectively. T...

ConclusionsSLNB is a minimally invasive and highly reliable method staging the cN0 for patients with early OSCC. Completion neck dissection of level I-III in SLNB-positive patients might be sufficient in patients with early TSCC. Our study showed that SLNB was helpful in clarifying unexpected bilateral or contralateral metastatic drainage patterns. SLNB provides more accurate staging than elective neck dissection or wait and see policy.Legal entity responsible for the studyThe authors.FundingHas not received any funding.DisclosureAll authors have declared no conflicts of interest.

Objective: To explore the risk factors of cervical lymph node metastasis in oral squamous cell carcinoma (OSCC) patients with clinical negative cervical lymph nodes(cN0) and provide a reference for clinical treatment.Methods: The clinical data of 161 OSCC patients with cN0 were retrospectively analyzed. All patients underwent extended primary resection combined with cervical lymph node dissection. The level and number of cervical lymph node metastasis were confirmed by postoperative pathology. The risk factors of cervical lymph node metastasis in patients were analyzed by univariate and multivariate Logistic regression ana...

Conclusions In the span of a very short time—less than a decade—robotic head and neck surgery has transformed the management of the head and neck cancer, and it seems clear that the future of treatment for these cancers lies in a multimodal approach in which TORS is likely to play an important role. Nevertheless, it is important to keep in mind that the current indications for TORS are limited and long-term data on the safety and oncological outcomes are needed to better understand the true role of TORS in treatment of head and neck cancer. Nonetheless, the emergence of ever more advanced robotic instruments i...

Conclusion: The clinicopathologic parameters such as site of cancer (P = 0.03), histologic differentiation (P = 0.03), shape of rete pegs (P = 0.002), pattern of invasion (P = 0.0001) and depth of invasion >3 mm (P = 0.016) were significantly associated with the risk of lymph node metastasis. The risk score devised based on these predictors serves as an efficient tool in aiding clinical decision-making regarding the extent of neck dissection.
