Purpose
To underline discrepancies between the Union for International Cancer Control (UICC) and the American Joint Committee on Cancer (AJCC) Tumor-Node-Metastasis (TNM) classifications in oral ...cavity cancer.
Methods
Comparison between the UICC and AJCC TNM classifications of oral cavity cancer in their 8th editions and following versions.
Results
The most important update was the introduction of the depth of infiltration (DOI), which reflects the proximity of the tumor to the underlying lymphovascular tissues and was associated to the presence of nodal metastases. Since the first publication of the 8th edition of the AJCC Cancer Staging Manual on March 30, 2017, two further versions have been published, while the UICC TNM classification was left unchanged until a document containing modifications to the 8th edition of the UICC TNM Classification of Malignant Tumours was published online on October 6, 2020.
Conclusion
Different versions of the TNM classification can be confounding for the scientific community. Citing the 8th edition of the UICC TNM Classification of Malignant Tumours or the AJCC Cancer Staging Manual without specifying the precise version used for classification may be insufficient. Clinicians and researchers are invited to always refer to the latest update of each classification.

Pilomatrix carcinoma is a rare tumor that is generally not diagnosed clinically. An 80-year-old man presented with a 5-month history of rapidly growing nodule of the submandibular area. Histological ...examination revealed a pilomatrix carcinoma, an aggressive malignancy with metastatic potential.
•Occult metastases in level 2b are rarely found in cN0 patients with OSCC.•Occult metastasis in level 2b is usually associated with metastasis in level 2a.•Sparing level 2b in these patients is ...oncologically reasonable.
Elective neck dissection of levels I, II and III is being increasingly used for detecting occult node metastases in patients with oral squamous cell carcinoma (OSCC) and clinically negative neck (cN0). The most frequent potential long-term complication of this procedure is shoulder dysfunction, because of micro- or macroscopic damage to the spinal accessory nerve (SAN). In particular, many studies have reported an association between SAN damage and dissection of level 2b. Furthermore, level 2b dissection is a technically demanding and time-consuming procedure. Our study aims to clarify whether level 2b sparing in cN0 patients with OSCC can be oncologically justifiable.
The PubMed, Cochrane and Scopus databases were searched by three different authors for articles on this topic. The primary endpoint of the meta-analysis was the overall prevalence of occult metastases in cervical level 2b nodes in patients with OSCC and clinically negative neck. The meta-analysis was performed using R version 4.0.1.
A total of 13 studies and 937 patients were included. The cumulative rate of occult nodal metastases in level 2b was 0.8% (n = 937, 95% CI: 0.1% − 2.2%, τ2 = 0.004). No isolated level 2b metastases was found among the patients with positive level 2b, and in the six studies that reported this association, all patients with nodal disease in level 2b had a positive level 2a.
This meta-analysis highlights how level 2b can be safely spared in supraomohyoid neck dissection (SOHND) of patients with OSCC and clinically negative neck, reducing the risk of postoperative shoulder dysfunction.

Objective
To provide real‐life evidence on long‐term radiological changes in patients with severe chronic rhinosinusitis with nasal polyps (CRSwNP) treated with dupilumab, and to assess possible ...differences between radiological and clinical results in terms of endoscopic findings and Patient‐Reported‐Outcomes (PROs).
Methods
Consecutive patients treated with dupilumab for recalcitrant CRSwNP were required to undergo CT scan at baseline (T0) and after 12 (T1) since first administration. A group of patients also performed CT scan at 52 weeks (T2) to assess long‐term outcomes. At each timepoint, patients underwent nasal endoscopy, assessment of Nasal‐Polyp‐Score (NPS), Lund‐Kennedy‐Score (LKS), and had to fill in the 22‐item Sinonasal‐Outcome‐Test (SNOT‐22) and Visual‐Analogue‐Scales (VAS) for sinonasal symptoms.
Results
In fifty‐three included patients, from T0 to T1 we detected a significant reduction in mean Lund‐Mackay score (LM), PROs (SNOT‐22, VAS) and endoscopic (NPS, LKS) scores (p < 0.05). In the subset of patients that reached T2 (n = 30), compared to T1, we observed a further significant decrease in mean LM, SNOT‐22, VAS, and NPS scores, but not in LKS (p = 0.420). At T1, the highest improvement was observed in PROs (SNOT‐22: 56.26%), and polyp size (NPS: 49.83%). Conversely, between T1 and T2, sinus opacification was shown to be the most improved outcome (LM: 36.86%).
Conclusions
Our experience showed that poorly controlled CRSwNP patients treated with dupilumab experienced significant improvement in radiologic, endoscopic and clinical disease severity. While in the initial 3 months, PROs garnered attention for showing earlier effectiveness, radiological outcomes revealed sustained and gradual efficacy in a longer term.
Level of Evidence
Level 4. According to the Oxford Center for Evidence‐Based Medicine 2011 level of evidence guidelines, this non‐randomized retrospective cohort study is classified as level 4 evidence Laryngoscope, 134:2626–2633, 2024
Our study showed that poorly controlled CRSwNP patients treated with dupilumab experienced a significant enhancement in radiologic, endoscopic, and clinical disease severity. While in the initial three months, patient‐reported outcomes garnered attention for showing prompt effectiveness, radiological outcomes revealed sustained and gradual improvement in a longer term.

Epithelial–mesenchymal transition (EMT) has been suggested to have a driving role in the acquisition of a metastatic potential by melanoma cells. Important hallmarks of EMT include both E-cadherin ...downregulation and increased expression of N-cadherin. This switch in distinct classes of adhesion molecules leads melanoma cells to lose contact with adjacent keratinocytes and interact instead with stromal fibroblasts and endothelial cells, thus promoting dermal and vascular melanoma invasion. Consequently, tumor cells migrate to distant host tissues and establish metastases. A key regulator in the induction of EMT in melanoma is the Notch1 signaling pathway that, when activated, is prompt to upregulate N-cadherin expression. By means of this strategy, melanoma cells gain enhanced survival, proliferation and invasion properties, driving the tumor toward a more aggressive phenotype. On the basis of these statements, the present study aimed to investigate the possible association between N-cadherin and Notch1 presence in primary cutaneous melanomas and lymph node metastases. Our results from immunohistochemical analysis confirmed a positive correlation between N-cadherin and Notch1 presence in the same tumor samples. Moreover, this study highlighted that a concomitant high expression of N-cadherin and Notch1, both in primary lesions and in lymph node metastases, predicts an adverse clinical outcome in melanoma patients. Therefore, N-cadherin and Notch1 co-presence can be monitored as a predictive factor in early- and advanced-stage melanomas and open additional therapeutic targets for the restraint of melanoma metastasis.

The aim of this study is to determine whether the preventive positioning of a salivary bypass tube (SBT) after total laryngectomy (TL) reduces the incidence of postoperative pharyngocutaneous fistula ...(PCF) and pharyngeal stenosis (PS). This study was conducted in conformity with the PRISMA statement. 1960 patients with a median age of 62.0 years were included. A SBT was placed in 980 (50%) patients (SBT group). The cumulative PCF incidence in the SBT group was 15.8% (95% CI: 9.3–23.6). The measured pooled OR comparing PCF incidence in patients with SBT compared to those without was 0.40 (95% CI: 0.24–0.65). The pooled PS incidence in the SBT group was 12.3% (95% CI: 5.4–21.6). The measured pooled OR comparing PS incidence in patients with SBT compared to those without was 0.43 (95% CI: 0.24–0.65). PCF and PS could be prevented by the intra‐operative placement of a SBT.

The aim of this study was to assess the prognostic value of tumor volume in oropharyngeal squamous cell carcinoma (OPSCC). The study was performed according to the PRISMA guidelines. A total of 1417 ...patients with a median age of 59.3 years (IQR 57.5−60) were included. The combined Hazard Ratios (HRs) for overall survival (OS) were 1.02 (95% CI, 0.99−1.05; p = 0.21) for primary tumor volume (pTV) and 1.01 (95% CI, 1.00−1.02; p = 0.15) for nodal tumor volume (nTV). Regarding locoregional control (LRC), the pooled HRs were 1.07 (95% CI, 0.99−1.17; p = 0.10) for pTV and 1.02 (95% CI, 1.01−1.03; p < 0.05) for nTV. Finally, the pooled HRs for disease-free survival (DFS) were 1.01 (95% CI, 1.00−1.03; p < 0.05) for pTV and 1.02 (95% CI, 1.01−1.03; p < 0.05) for nTV. In conclusion, pTV and nTV seem not to behave as reliable prognostic factors in OPSCC.

Purpose
To define the accuracy of fine‐needle aspiration cytology (FNAC) in diagnosing persistent or recurrent neck metastases in previously irradiated patients.
Methods
The study was performed ...according to the PRISMA‐DTA guidelines.
Results
A total of 382 FNACs were used for calculation of diagnostic accuracy parameters. The overall pooled sensitivity and specificity in detecting malignant nodes were 69.1% (95% CI: 56.3%‐80.7%; I2 = 79.5%) and 84.2% (95% CI: 71.8%‐93.5%; I2 = 87.0%), respectively. Cumulative diagnostic odds ratio (DOR) was 16.54 (95% CI: 4.89‐38.99; I2 = 65.8%), while cumulative positive and negative likelihood ratio (PLR and NLR) were 5.4 (95% CI: 2.3‐11.2) and 0.37 (95% CI: 0.22‐0.54), respectively.
Conclusions
FNAC alone could not guide the decision to perform a salvage neck dissection in previously irradiated patients, but its results should be assessed in relation to the specific clinical context.

Primary localized cutaneous nodular amyloidosis (PLCNA) is a rare condition due to the plasma cell proliferation and skin deposition of immunoglobulin light chains, without systemic amyloidosis or ...hematological dyscrasias. The association with autoimmune connective tissue diseases has been reported, especially with Sjogren’s syndrome, and in a few cases with systemic sclerosis. Herein, we describe three cases of PLCNA occurring in women with a diagnosis of limited cutaneous systemic sclerosis and review the literature on the topic to highlight a stereotypical presentation. Moreover, we support the usefulness of dermoscopy, characterized by a yellow–orange waxy pattern surrounded by telangiectasias, for a rapid and non-invasive diagnostic assessment. Thus, when asymptomatic nodules occur on lower limbs of women affected with limited systemic sclerosis, and dermoscopy identifies yellow–orange blotches, a diagnosis of PLCNA can be considered and further confirmed by histopathology. Monitoring for systemic amyloidosis development is advisable, although the risk of progression is considered very low.
