We evaluated the efficacy of dose de-escalation to the normal larynx using conformal radiotherapy (CRT) for T1/T2 glottic cancer. For conventional RT (2DRT, n = 38), the laryngeal box received a median equivalent dose in 2 Gy fractions (EQD2) of 66 Gy. For CRT (n = 42; 3D-CRT, 20; intensity-modulated RT, 22), clinical target volume (CTV)1 (gross tumor with a 3-mm margin) and CTV2 (laryngeal box) received median EQD2s of 66.6 Gy and 52.2 Gy, respectively. With a 71-month median follow-up, five-year local control and overall survival rates for 2DRT vs...

Laryngeal squamous cell carcinoma (LSCC) is one of the most common head and neck cancer, with high mortality and incidence. MicroRNA-26a (miR-26a) is involved in the development and progression of several tumors. However, the roles of miR-26a and its target CKS2 in LSCC progression are not yet clear. The mRNA and protein expression was determined using RT-PCR and Western blotting assay, respectively. Cell proliferation was detected using a Cell Counting kit-8 assay (CCK-8). Transwell assay was used to evaluate cell migration and invasion...

Lymph nodes posterior to the right recurrent laryngeal nerve (LN-prRLN) are common sites of nodal recurrence after the resection of papillary thyroid carcinoma (PTC). However, the indication for LN-prRLN dissection remains debatable. We therefore studied the relationships between LN-prRLN metastasis and the clinicopathological characteristics in 306 patients with right or bilateral PTC who underwent LN-prRLN dissection. We found that LN-prRLN metastasis occurred in 16.67% of PTC and was associated with a number of the clinicopathological features...

Answer questions and earn CME/CNE This is a review of the major changes in the American Joint Committee on Cancer staging manual, eighth edition, for differentiated and anaplastic thyroid carcinoma. All patients younger than 55 years have stage I disease unless they have distant metastases, in which case, their disease is stage II. In patients aged 55 years or older, the presence of distant metastases confers stage IVB, while cases without distant metastases are further categorized based on the presence/absence of gross extrathyroidal extension, tumor size, and lymph node status...

MicroRNAs (miRNAs) are aberrantly expressed in several tumors and play important role in tumorigenesis. However, little is known about the role of miR-613 in laryngeal squamous cell carcinoma (LSCC). We determined the expression of miR-613 in a panel of 30 LSCC specimens. Compared with the adjacent normal samples, 20 cases of LSCC tissues exhibited decreased expression of miR-613. The average expression of miR-613 in LSCC tissues was lower than in normal samples. Moreover, we demonstrated that exogenous expression of miR-613 suppressed LSCC cell proliferation, invasion and blocked G1/S phase transition...

Laryngeal carcinoma (LC) is one of the most prevalent malignant tumors in the head and neck area. Due to its high morbidity and mortality, LC poses a serious threat to human life and health. Even with surgical removal, some patients were not sensitive to radiotherapy or experienced transfer or recurrence. 20(s)-Protopanaxadiol (PPD), a natural product from Panax ginseng, has been reported to have cytotoxic effects against several cancer cell lines. However, whether it can improve the radiation sensitivity and the underlying mechanism of PPD's sensitization effect is still unknown...

Human cytomegalovirus (CMV) is an infectious herpes virus present in approximately 50% of the world's population. Pharyngitis is an uncommon manifestation of CMV infection, and vocal cord immobility (VCI) following CMV pharyngitis is quite rare. An 83-year-old man with well-controlled diabetes mellitus and hypertension was admitted due to dyspnea, odynophagia, and dysphagia. Laryngeal fiberscopy revealed bilateral vocal cords almost fixed at the median position, with mucosal redness, swelling, and edema at the hypopharyngeal area...

OBJECTIVE: Total laryngectomy is a well-established treatment for locally advanced laryngeal cancer. Evidence for the benefit of post-operative radiotherapy after laryngectomy in patients with locally advanced primaries and N0 or N1 nodal disease is limited. This study aims to determine whether total laryngectomy alone is adequate therapy for certain patient subgroups with locally advanced laryngeal cancer. DESIGN: We performed a retrospective survival analysis of patients in the surveillance epidemiology and end results (SEER) database with locally advanced laryngeal cancer between 2004-2012...

Accumulating evidence has shown that aberrant lncRNA expression plays an oncogenic or tumor-suppressive role in the tumorigenesis of laryngeal cancer. However, the prognostic roles of lncRNAs in laryngeal cancer recurrence are still poorly understood. In this study, we obtained lncRNA expression profiles of 109 patients with laryngeal cancer by mining previously published gene expression microarray data from the Gene Expression Omnibus (GEO) and identified two lncRNAs associated with laryngeal cancer recurrence in the training dataset by using Cox regression analysis...
