Is the positive predictive value of high-grade cytology in predicting high-grade cervical disease falling due to HPV vaccination?

Int J Cancer 2018 Dec 10. Epub 2018 Dec 10.

VCS Population Health, VCS Foundation, Level 6, 176 Wellington Parade, East Melbourne, VIC, 3002, Australia.

A fall in the positive predictive value (PPV) of cytological predictions of high-grade squamous intraepithelial lesions (HSIL) or adenocarcinoma-in-situ (AIS) has been predicted in the post HPV vaccination era due to the decrease in underlying prevalence of cervical lesions. Data was extracted from the Victorian Cervical Screening Registry including cervical cytology tests taken between 2000 and 2016 and any subsequent histology performed within six months of the cytology. PPV was calculated for each age group (<20, 20-24, 25-29, 30-34, 35-39, 40-49, 50-59, 60-69, 70+ years) and calendar year. Read More

Sclerosis of the arytenoid cartilage and glottic carcinoma: A clinical-pathological study.

Head Neck 2018 Dec 7. Epub 2018 Dec 7.

Otolaryngology Unit, Vittorio Veneto Hospital, Treviso, Italy.

Background: Given the relevance of any tumor invasion of the arytenoid cartilage or crico-arytenoid unit to the planning open partial horizontal laryngectomy (OPHL) for laryngeal squamous cell carcinoma (LSCC), it is important to have a reliable radiological test to assess impairments of these structures.

Methods: We retrospectively compared the endoscopic, radiological, and pathological findings in patients with glottic LSCC who underwent OPHL.

Results: The endoscopic finding of a reduced (impaired or absent) vocal cord motility proved more sensitive, with better positive and negative predictive values, but less specific than the radiological finding of complete arytenoid sclerosis in detecting histologically assessable infiltration of the arytenoid cartilage.

Division of Rhinology, Department of Otolaryngology-Head and Neck Surgery, St. Michael's Hospital, University of Toronto, Toronto, ON, Canada.

Background: Previous studies on the impact of wait times for endoscopic sinus surgery (ESS) in medically recalcitrant chronic rhinosinusitis (rCRS) have not examined its influence on the 5 distinct symptoms domains of the 22-item Sino-Nasal Outcome Test (SNOT-22), and have not applied evidence-based surgical indications. Our primary study objective was to investigate the impact of ESS wait times on postoperative SNOT-22 global and symptom domain scores in patients with rCRS deemed "appropriate" surgical candidates.

Superior detection of metastatic cystic lymphadenopathy in patients with papillary thyroid cancer by utilization of thyroglobulin washout.

Head Neck 2018 Dec 9. Epub 2018 Dec 9.

Division of Endocrine and Oncologic Surgery, Department of Surgery, Tulane University School of Medicine, New Orleans, Louisiana.

Background: Fine-needle aspiration (FNA) cytology has been the standard of care in the workup of cervical lymph nodes (LNs) in patients with recurrent papillary thyroid cancer (PTC) and suspicious cervical LNs. Recently, FNA thyroglobulin (TG) washout measurement has been proposed as an adjunct in the management of these patients. We hypothesize that using FNA-TG washout for suspicious cervical LNs would increase the accuracy of diagnosing metastatic disease especially in cystic and highly vascular cervical LN in patients with recurrent PTC.

EPID-based in vivo dosimetry using Dosimetry Check™: Overview and clinical experience in a 5-yr study including breast, lung, prostate, and head and neck cancer patients.

J Appl Clin Med Phys 2018 Dec 7. Epub 2018 Dec 7.

Department of Oncology Physics, Edinburgh Cancer Centre, Western General Hospital, Edinburgh, UK.

Background: Independent verification of the dose delivered by complex radiotherapy can be performed by electronic portal imaging device (EPID) dosimetry. This paper presents 5-yr EPID in vivo dosimetry (IVD) data obtained using the Dosimetry Check (DC) software on a large cohort including breast, lung, prostate, and head and neck (H&N) cancer patients.

Material And Methods: The difference between in vivo dose measurements obtained by DC and point doses calculated by the Eclipse treatment planning system was obtained on 3795 radiotherapy patients treated with volumetric modulated arc therapy (VMAT) (n = 842) and three-dimensional conformal radiotherapy (3DCRT) (n = 2953) at 6, 10, and 15 MV.

Proliferative verrucous leukoplakia and its tumor markers: Systematic review and meta-analysis.

Head Neck 2018 Dec 11. Epub 2018 Dec 11.

Faculty of Medicine, Department of Oral Pathology, Institute of Dentistry, University of Turku, Turku, Finland.

Background: The aim was to update information on oral proliferative verrucous leukoplakia (PVL), a disease of verrucous-like lesions with high risk of malignancy, and its biomarkers.

Methods: A systematic search of literature on PVL and its biomarkers showed 22 biomarkers that were investigated in 19 papers. A meta-analysis was possible for human papillomavirus (HPV), aneuploidy, Ki-67, and p53. Read More

Venous thromboembolism in head and neck surgery: Risk, outcome, and burden at the national level.

Head Neck 2018 Dec 7. Epub 2018 Dec 7.

Department of Surgery, Tulane University School of Medicine, New Orleans, Louisiana.

Background: Venous thromboembolism (VTE) can complicate major surgeries. This study examines the risk and outcomes of VTE in patients who underwent head and neck surgeries.

Methods: Retrospective cross-sectional analysis utilizing the Nationwide Readmissions Database (2010-2014). Read More

Ototoxicity in locally advanced head and neck cancer patients treated with induction chemotherapy followed by intermediate or high-dose cisplatin-based chemoradiotherapy.

Head Neck 2018 Dec 7. Epub 2018 Dec 7.

Department of Medical Oncology, Radboud University Medical Center, Nijmegen, The Netherlands.

Background: This study evaluated ototoxicity in locally advanced head and neck cancer patients treated in the CONDOR study with docetaxel/cisplatin/5-fluorouracil (TPF) followed by conventional radiotherapy with concomitant cisplatin 100 mg/m on days 1, 22, and 43 (cis100+RT) versus accelerated radiotherapy with concomitant cisplatin weekly 40 mg/m (cis40+ART).

Methods: Sixty-two patients were treated in this study. Audiometry was performed at baseline, during TPF, before start of chemoradiotherapy, and 1, 4, 8, and 12 months after treatment. Read More

Pathway based prognostic gene expression profile of buccal and gingivo-buccal oral squamous cell carcinoma in smokeless tobacco chewers.

Head Neck 2018 Dec 11. Epub 2018 Dec 11.

MDS, Department of Oral and Maxillofacial Surgery, Faculty of Dental Sciences, Ramaiah University of Applied Sciences, Bengaluru, Karnataka, India.

Background: The objective was to study comprehensive mRNA expression profiles of buccal mucosa oral squamous cell carcinoma (OSCC-BM) and gingivo-buccal OSCC (OSCC-GB) in smokeless tobacco chewers to understand the biological behavior of OSCC at these specific sites and identify diagnostic and prognostic markers.

Methods: High throughput RNA sequencing transcriptome of fresh buccal mucosa (4 samples) and gingivo-buccal (4 samples) OSCC with normal oral mucosa (3 samples) was performed on Illumina NextSeq500 paired end sequencing with 75x2bp.

Results: In the comparison between OSCC and normal, there were 402 differentially expressed genes (DEGs); between OSCC-BM and normal, there were 467 DEGs; and between OSCC-GB and normal oral tissue, there were 608 DEGs. Read More
