Head neck oncology

BACKGROUND AND PURPOSE: Radiotherapy (RT) can damage neck vessels in patients with head and neck cancer (HNC). This study investigated the early effects of RT on carotid artery, including the internal media thickness (IMT) and carotid plaques of the common carotid artery (CCA). MATERIALS AND METHODS: This study included 69 patients with HNC who underwent RT at the First Hospital of Jilin University from March 2017 to September 2022, and 69 healthy participants as controls...

PURPOSE: The experience of long-term pain in head and neck cancer (HNC) survivors is important but has received less attention in the HNC literature. The present study sought to examine the prevalence of pain from 2 to 5 years postdiagnosis and its association with HNC-specific health-related quality of life. MATERIALS & METHODS: Prospective observational study at a single-institution tertiary care center. Pain was measured using a single item ranging from 0 to 10 with 0 representing no pain and 10 representing worst pain possible at 2 through 5 years postdiagnosis...

OBJECTIVES: To assess the value of carbon dioxide transoral laser microsurgery (CO2 TOLMS) for early-stage glottic cancer with special regard to involvement of the anterior commissure (AC). STUDY DESIGN: Single-center retrospective cohort study. SETTING: Grade-A tertiary hospital. METHODS: A retrospective analysis of patients with early-stage (Tis-T2) glottic cancer who underwent CO2 TOLMS. All patients had at least 2 years of follow-up...

Head and neck squamous cell carcinoma (HNSCC) is a highly aggressive, heterogeneous tumour usually caused by alcohol and tobacco consumption, making it one of the most common malignancies worldwide. Despite the fact that various therapeutic approaches such as surgery, radiation therapy (RT), chemotherapy (CT) and targeted therapy have been widely used for HNSCC in recent years, its recurrence rate and mortality rate remain high. RT is the standard treatment choice for HNSCC, which induces reactive oxygen species production and causes oxidative stress, ultimately leading to tumour cell death...

The complex evolution of genetic alterations in cancer that occurs in vivo is a selective process involving numerous factors and mechanisms. Chemotherapeutic agents that prevent the growth and spread of cancer cells induce selective pressure, leading to rapid artificial selection of resistant subclones. This rapid evolution is possible because antineoplastic drugs promote alterations in tumor‑cell metabolism, thus creating a bottleneck event. The few resistant cells that survive in this new environment obtain differential reproductive success that enables them to pass down the newly selected resistant gene pool...

Tracheoesophageal puncture and voice prosthesis placement is the preferred method of voice restoration following total laryngectomy. Although this is a safe and effective means of optimizing voice, severe complications can occur. We present the case of a patient who developed cerebritis and ventriculitis secondary to a tracheoesophageal prosthesis eroding his cervical vertebrae 20 years following pharyngo-laryngo-esophagectomy. Despite optimal antimicrobial therapy, he deteriorated and succumbed to his disease...

INTRODUCTION: In the era of personalized medicine and treatment optimization, use of immune biomarkers holds promise for estimating the prognosis of patients with head and neck squamous cell carcinoma (HNSCC) undergoing definitive treatment. METHODS: To evaluate the prognostic potential of immune biomarkers, we conducted a prospective monocentric cohort study with loco-regionally advanced HNSCC patients indicated for definitive radiotherapy/radiochemotherapy at the Department of Oncology, Ostrava University Hospital, Czech Republic, between June 2020 and August 2023...

INTRODUCTION: Head and neck cancer is an umbrella term for tumor manifestations across the head and neck regions, including the oral cavity, pharynx (including the naso, oro, and hypopharynx), larynx, and sinuses. Treatment options for head and neck cancer include surgery, radiation therapy, chemotherapy, and immunotherapy, with specific treatment plans depending upon individual tumor location and staging, together with overall patient health status. Furthermore, definitive chemoradiotherapy (CRT) has emerged as a highly effective therapeutic option for locoregional advanced head and neck squamous cell cancer...

BACKGROUND: Informal caregivers (ICs) of patients with cancer provide essential and mainly uncompensated care. A self-perceived preparedness to care for the patient is associated with a lower caregiver burden, described as the extent to which caregiving is perceived as having adverse effects on IC functioning and well-being. ICs' well-being is associated with patient-perceived quality of care, suggesting that interventions to optimize ICs' health are essential in order to improve patient care...

Advancements in technology and technical expertise increasingly enable neurointerventionalists to deliver safer and more effective endovascular treatments to cancers of the brain, spine, head, and neck. In addition to established neuro-oncological interventions such as pre-surgical tumor embolization and percutaneous ablation, newer modalities focused on direct arterial infusion of chemotherapy, radioisotopes, and radiosensitizers continue to gain traction as complementary treatment options, while stem cell-mediated delivery of theranostic nanoparticles and oncolytic virus are being explored for even greater specificity in targeting cancers across the blood-brain barrier...

INTRODUCTION: Treatment planning using a five-millimetre geometrical margin from GTV to high-dose CTV (CTV1) has been used in DAHANCA treatment centres since 2013. We aimed to evaluate changes in CTV1 volumes, local control (LC), and recurrence pattern after the implementation of five-millimetre geometrical margins nationally. MATERIALS AND METHODS: 1,948 patients with pharyngeal, and laryngeal squamous cell carcinomas completed definitive IMRT-based treatment in 2010-2012 and 2013-2015 in three centres...

PURPOSE: The optimal management of local-regionally recurrent head and neck cancer that is not amenable to surgical resection is uncertain. We sought to compare outcomes among patients treated with and without re-irradiation in this setting. METHODS AND MATERIALS: A review of institutional registries identified 65 patients with local-regionally recurrent squamous cell carcinoma of the head and neck who were ineligible for surgery. Forty patients (62 %) opted for re-irradiation with the remaining 25 patients (38 %) undergoing initial systemic therapy alone...

BACKGROUND AND PURPOSE: This multicenter randomized phase III trial evaluated whether locoregional control of patients with LAHNSCC could be improved by fluorodeoxyglucose-positron emission tomography (FDG-PET)-guided dose-escalation while minimizing the risk of increasing toxicity using a dose-redistribution and scheduled adaptation strategy. MATERIALS AND METHODS: Patients with T3-4-N0-3-M0 LAHNSCC were randomly assigned (1:1) to either receive a dose distribution ranging from 64-84 Gy/35 fractions with adaptation at the 10thfraction (rRT) or conventional 70 Gy/35 fractions (cRT)...

BACKGROUND AND OBJECTIVE: Little is known about malignant central airway obstruction (MCAO) complicating the metastatic spread of non-bronchogenic solid cancers (NBC) and their bronchoscopic management. This study aimed to describe the epidemiology of this population and determine prognostic factors before therapeutic bronchoscopy (TB). METHODS: In this multicenter study using the EpiGETIF registry, we analysed patients treated with TB for MCAO caused by NBC between January 2019 and December 2022...

BACKGROUND AND PURPOSE: Diffusion-weighted imaging (DWI) is a promising technique for response assessment in head-and-neck cancer. Recently, we optimized Non-Gaussian Intravoxel Incoherent Motion Imaging (NG-IVIM), an extension of the conventional apparent diffusion coefficient ( ADC ) model, for the head and neck. In the current study, we describe the first application in a group of patients with human papillomavirus (HPV)-positive and HPV-negative oropharyngeal squamous cell carcinoma...

BACKGROUND AND PURPOSE: Retrospective dose evaluation for organ-at-risk auto-contours has previously used small cohorts due to additional manual effort required for treatment planning on auto-contours. We aimed to do this at large scale, by a) proposing and assessing an automated plan optimization workflow that used existing clinical plan parameters and b) using it for head-and-neck auto-contour dose evaluation. MATERIALS AND METHODS: Our automated workflow emulated our clinic's treatment planning protocol and reused existing clinical plan optimization parameters...

US Preventive Services Task Force (USPSTF) guidelines recommend single-cancer screening for select cancers (e.g., breast, cervical, colorectal, lung). Advances in genome sequencing and machine learning have facilitated the development of blood-based multi-cancer early detection (MCED) tests intended to complement single-cancer screening. MCED tests can interrogate circulating cell-free DNA to detect a shared cancer signal across multiple tumor types. We report real-world experience with an MCED test that detected cancer signals in three individuals subsequently diagnosed with cancers of the ovary, kidney, and head/neck that lack USPSTF-recommended screening...

BACKGROUND AND PURPOSE: Previous studies have shown that the mean dose to the parotid gland stem cell rich regions (Dmean,SCR ) is the strongest dosimetric predictor for the risk of patient-reported daytime xerostomia. This study aimed to test whether the relationship between patient-reported xerostomia and Dmean,SCR is explained by a dose-dependent reduction of saliva production. MATERIAL/METHODS: In 570 head and neck cancer patients treated with definitive radiation therapy (RT), flow from the parotid (FLOWPAR ) and submandibular/sublingual glands (FLOWSMSL ) and patient-reported daytime (XERDAY ) and nighttime xerostomia (XERNIGHT ) were prospectively measured before, and at 6 and 12 months after RT...

This review aims to provide a correlation between oral and oropharyngeal subsites and type of reconstruction used in the management of head and neck cancer patients. A literature search of PubMed, Embase and Web of Science was conducted. All study types describing long-term speech and swallow outcomes of adults following head and neck oncological reconstruction, which used a subsite classification, were included. Risk of bias was assessed using the Robbins-1 tool. A total of 2270 patients were found in 26 studies...
