Clinical course and survival in patients with squamous cell carcinoma of the maxillary alveolus and hard palate: results from a single-center prospective cohort

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.

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...

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.

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.

ConclusionTreatment with tumor excision, lymph node dissection and reconstruction by local flap is primary treatment for patients with lower lip cancer. Choice of reconstruction method depends on various factors, whereas V-Y advancement flap presents dominant advantage in lower lip cancer treatment.

Abstract Oral squamous cell carcinoma (OSCC) with invasion into the mandibular medullary space has been reported to be a predictive factor for cervical lymph node metastasis (CLNM). As CLNM has been associated with the stemness of cancer cells, we aimed to evaluate the relationship between clinical characteristics and immunohistochemical findings on the invasion front of the medullary invasive OSCC and CLNM. The medical records of 25 patients with the mandibular medullary invasive OSCC who were performed mandibulectomy and neck dissection in our department from 2010 to 2016 were examined. Serial sections were stai...

ConclusionIn this study, reliability of sentinel lymph node biopsy after ICG imaging could not be verified, as there were false-negative results in 50% of the cases. Therefore, SND can still be recommended as for patients with cT1 or cT2 OSCC, and a N0 neck status.

In conclusion, DOI measurement for SCC of the oral tongue may require re-examination of the diagnostic biopsy in up to 20% of cases due to the absence or o nly minimal residual carcinoma in glossectomy specimens. In 11.5% of apparently pT2 cases, DOI may be underestimated due to the positive deep margin. Rarely, extratumoral PNI or lymphatic invasion may be the deepest point of invasion. Overall, two issues (absent or minimal residual disease and posit ive deep margin) may confound DOI measurement in early SCCs of oral tongue.
