Objective: To elucidate the prognostic implications of mucosal and deep margin distances in oral tongue squamous cell carcinoma (OTSCC), and to assess a different margin cut-off value in T1-T2 versus T3-T4 tumors.

Methods: This single-center retrospective study included 223 patients who received surgery for a primary OTSCC between January 2017 and December 2021.

Results: Multivariable analysis showed that deep margin distance ≥3 mm in T1-T2 tumors and ≥5 mm in T3-T4 tumors was significantly associated with better RFS and OS. Mucosal and deep margin distances were globally clinically useful for 2-year RFS prediction of T1-T2 tumors, for which deep margins seemed to have more clinical utility than mucosal margins. The influence of margin distances on 2-year RFS seemed greater for T1-T2 tumors than T3-T4 tumors.

Conclusion: Mucosal and deep margin distances were associated with OS and RFS in OTSCC. Shorter deep margin distances may be aimed for in T1-T2 versus T3-T4 tumors.

Background: To investigate feasibility of utilizing enhanced neuromuscular blocking agents with selective recovery protocol during thyroid surgery with intraoperative neuromonitoring (IONM).

Methods: Two-hundred and ninety patients were randomized into two groups: group A 0.3 mg/kg rocuronium and group B 0.6 mg/kg. Sugammadex 2 mg/kg was injected if needed followed initial vagal stimulation (V0). Electromyography signals from vagus and recurrent laryngeal nerves before and after resection were recorded as V1, V2, R1, and R2.

Results: In group B, 30 patients (20.7%) had V0 signals <100 μV, compared to 9 (6.2%) in group A. After sugammadex administration, 144 patients (99.3%) in both groups achieved positive V1 signals. Group B demonstrated a shorter surgical time from rocuronium injection to V2 stimulation compared to group A, accompanied by a significantly lower incidence of intraoperative body movement (0 vs. 16 patients).

Conclusions: 0.6 mg/kg rocuronium with selective use 2 mg/kg sugammadex for IONM in thyroid surgery can meet both anesthesia and surgery demands.

Background: While preventive swallowing exercises reduce the risk of radiation-associated dysphagia in patients with head and neck cancer, strategies are needed to improve patient adherence.

Methods: Before radiation, all participants were taught preventive swallowing exercises and randomized to either an adherence intervention or enhanced usual care. During radiation, all participants met twice with a speech pathologist for swallowing assessment and reinforcement of exercises. Intervention participants met weekly with a counselor in-person or by phone. At 6-week post-radiation follow-up, all participants completed a follow-up assessment of self-reported adherence, which was then corroborated with medical record documentation.

Results: Newly diagnosed pharyngeal and laryngeal cancer patients without distant metastases were randomized (n = 265; 135 to intervention, and 130 to usual care). Intervention participants were more likely to adhere to exercises during radiation compared to the control group (p < 0.0001).

Conclusion: The weekly in-person adherence intervention program significantly increased patient's adherence to preventive swallowing exercises during radiation.

Background: Ear and temporal bone squamous cell carcinoma (ETBSCC) is a rare and aggressive malignant tumor with minimal clinicopathological studies. The object of this study was to retrospectively evaluate the predictive effect of clinicopathological variables on the 5-year overall survival (OS) rate of ETBSCC patients in a single tertiary medical center in Tianjin, China.

Methods: A cohort of 44 patients with diagnosed ETBSCC from December 2012 to August 2022 were retrospectively studied. Univariate and multivariate analysis were, respectively, performed for the assessment of clinicopathological predictors, including sex, age, history of chronic suppurative otitis media (CSOM), lesion side, diameter, the choice of surgical approach, parotidectomy, neck dissection, adjuvant therapies, T stage, lymph node metastasis, tumor grade, margin, perineural invasion (PNI), and Ki-67 index.

Results: Seventeen females and 27 males were included, with the mean age of 65 years old, ranging from 36 to 89 years. The 5-year OS rate was 43% (mean 51 months, 95% confidence interval [CI] = 39-64). Significant prediction of a worse prognosis for 5-year OS rate was observed under univariate analysis for advanced T stage, positive margin, identified PNI, and higher Ki-67 index, respectively. Advanced T stage was confirmed to be an independent prognostic factor strongly affecting 5-year OS rate among this cohort of patients using a multivariate cox proportional hazard model.

Conclusion: We found that clinicopathological parameters, especially postoperative pathological parameters, play a critical role in predicting the prognosis of ETBSCC patients.

Background: The impact of timing of PORT initiation for major salivary gland cancers on survival is unknown. We aim to examine the impact of PORT timeliness on overall survival (OS) of patients with major salivary gland cancers.

Methods: This was a cross-sectional analysis using data from the National Cancer Database (2004-2017) and included patients with major salivary gland cancer treated with surgery and PORT.

Results: In total, 5701 patients were included (3133 [55%] male, 4644 [82%] white, mean age 59 ± 16 years). For the overall cohort, PORT >6 weeks was not associated with decreased OS (1.00 aHR, 95% CI 0.89-1.11). When specifically examining patients with mucoepidermoid carcinoma, PORT >6 weeks was associated with a decreased OS (1.27 aHR, 95% CI 1.01-1.58).

Conclusions: Overall, this analysis did not demonstrate a survival benefit for initiating PORT within 6 weeks for patients with salivary gland malignancies. Subset analysis did support initiating PORT within 6 weeks after resection for patients with mucoepidermoid carcinomas. This was not demonstrated in other major salivary gland cancer histologies.

We conducted a systematic review of the literature to assess the potential prognostic utility of geriatric nutritional risk index (GNRI) for head and neck cancer (HNC). We selected studies and extracted data after searching the Cochrane Library, EMBASE, and PubMed databases. The associations between GNRI and survival outcomes were explored by calculating hazard ratios (HRs) and 95% confidence intervals (CIs) through a random-effects meta-analysis. We included 11 studies that involved 2887 patients with HNC. The combined HR demonstrated significant associations of low GNRI with unfavorable progression-free survival (HR = 1.87, 95% CI = 1.32–2.65, p < 0.001) and overall survival (HR = 3.04, 95% CI = 2.30–4.03, p < 0.001). The association between the GNRI and overall survival persisted across various subgroups. The GNRI could serve as a valuable prognostic biomarker for patients with HNC. Low GNRI scores are significantly associated with unfavorable survival outcomes.

Background: Pleomorphic adenoma (PA) is a common parotid tumor, yet due to the relative rarity of deep lobe PA (DLPA), there is a paucity of information about its clinical presentation and surgical outcomes.

Methods: We reviewed the charts of patients with previously untreated parotid PA between the years 1990 and 2015. Clinical parameters and surgical outcomes were compared between superficial lobe PA (SLPA) and DLPA.

Results: The cohort comprised 147 cases of DLPA and 222 cases of SLPA. DLPA were larger (median 2.6 cm vs. 2.0 cm, p < 0.001), more often discovered incidentally on imaging (33%, n = 48) and had unique presentations (pharyngeal mass, dysphagia, otalgia). Postsurgical complications were more frequently observed in DLPA (41% vs. 30% in SLPA, p = 0.025), mainly transient facial nerve weakness. DLPA also showed higher recurrence rates (n = 6, 4.1% vs. n = 1, 0.4%, p = 0.016).

Conclusions: Parotidectomy for DLPA carries a higher risk of complications and recurrence compared to SLPA.
