This case report elucidates an uncommon manifestation of toxoplasmosis characterized by an ulcerative oropharyngeal lesion and cervical lymphadenopathy, which intriguingly simulated a tonsillar neopla...
Osteoradionecrosis (ORN) is a rare but serious late complication of head and neck radiation therapy. The mandible, proximity of the primary tumor to the jawbones, radiation dose, poor oral hygiene, an...
Dendritic cells (DCs) are specialized antigen-presenting cells that play a critical role in the immune response against human papillomavirus (HPV) infection, and represent a therapeutic target in canc...
To identify and quantify DCs in tonsillar squamous cell carcinoma (TSCC) under the influence of HPV infection....
CD1a and CD83 antibodies were used to identify immature dendritic cells and mature dendritic cells by immunohistochemistry in 33 primary TSCC and 10 normal tonsils (NTs), respectively. For the TSCC sa...
There were fewer intratumoral CD1a+ DCs in the HPV-positive and HPV-negative TSCC groups than in the NT group (p<0.05). In the peritumoral compartment, there were fewer CD83+ DCs in the HPV-positive a...
Tumor activity contributes to DC depletion regardless of intralesional HPV positivity. An improved prognosis has been reported in patients with HPV-positive TSCC....
Unilateral radiation to cervical nodes has been used as a de-escalation strategy in well-lateralized tonsil cancers. The efficacy of this approach with multiple ipsilateral nodes is not established. T...
This study was a retrospective chart review of patients with AJCC-7 T1-2N2b tonsillar cancer from 2 academic institutions who were treated with unilateral radiation. The primary endpoint was the contr...
The study cohort included 66 patients treated between 2005 and 2016. The median follow-up time was 80.9 months; contralateral nodal failure occurred in 2/66 (3.0%) patients at 4.1 and 20.9 months, res...
The use of unilateral radiation for AJCC-7 T1-2N2b tonsillar cancer resulted in low rates of contralateral nodal failure. This outcome demonstrates the safety of considering unilateral radiation treat...
Soft tissue necrosis (STN) can occur after transoral robotic surgery (TORS) with radiation therapy (RT). We investigated the usefulness of local flap reconstruction for preventing STN after TORS in pa...
This case-control study retrospectively reviewed clinicopathological data of patients who underwent TORS for tonsillar cancer at a tertiary referral center. The incidence of STN was compared in patien...
STN occurred in 20 (25%) of 80 patients in the study. The incidence of STN was higher in the secondary intention healing than the flap reconstruction group. Mucositis grade (odds ratio [OR] 3.694, p =...
Flap reconstruction can prevent STN after TORS with RT in patients with tonsillar cancer. The use of local flaps preserves the minimally invasive nature of TORS....
Esophageal submucosal tumors are rare, but their pathological types are diverse. In addition to the relatively common leiomyomas, some rare submucosal lesions are occasionally reported. Waldeyer's rin...
Functional outcomes of neoadjuvant chemotherapy in human papillomavirus (HPV)-positive tonsillar cancer remained unclear....
We retrospectively reviewed the medical records of HPV-positive patients with tonsillar cancer. Of 112 patients, 38 were assigned to a neoadjuvant chemotherapy group and 74 were assigned to an upfront...
Pathological analyses showed that the risks of close or positive resection margins and lymphovascular invasion were lower in patients who received neoadjuvant chemotherapy. The 5-year disease-free sur...
Compared with upfront surgery, neoadjuvant chemotherapy improved the functional outcomes and 5-year disease-free survival....
Given the uncertainty regarding the predictive value of unilateral tonsillar enlargement and/or lesion in malignancies, this study aimed to evaluate the efficacy of unilateral tonsillar enlargement an...
All two-week wait referrals received in 2018-2019 were reviewed. All patients referred with unilateral tonsillar enlargement and/or lesion were included and analysed for patient demographic data, pres...
A total of 4934 urgent head and neck cancer referrals were analysed, and 1.9 per cent of these had unilateral tonsillar enlargement and/or lesion. Only 10 patients were diagnosed with tonsil cancer. A...
The referral criterion for unilateral tonsillar enlargement and/or lesion may be of limited benefit in an already economically challenged National Health Service. Further multicentre studies should be...
Human-papillomavirus (HPV)-positive tonsillar and base of tongue carcinomas (TSCC/BOTSCC) are rising in incidence and treatments with radiotherapy, chemoradiotherapy (RT/CRT), and neck dissections (ND...
Patients with tonsillar cancer (TC) often have dental fillings that can significantly degrade the quality of computed tomography (CT) simulator images due to metal artifacts. We evaluated whether the ...
