Cytology-based Cancer Surgery of the Head and Neck (CyCaS-HN): a prospective, randomized, controlled clinical trial. Eur Arch Otorhinolaryngol 2022; 279:4505-4514. [PMID: 35305137 PMCID: PMC9363327 DOI: 10.1007/s00405-022-07333-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/10/2021] [Accepted: 02/28/2022] [Indexed: 11/29/2022]
Abstract
Purpose Liquid-based cytology (LBC) is routinely used in gynecology but is rarely applied in head and neck oncology though many suspicious lesions are easily accessible. While several studies have evaluated the potential use of LBC for early detection and molecular characterization of head and neck squamous cell carcinomas (HNSCCs), no study investigated its potential role in surgical management and therapy planning so far. Methods Twenty-five patients with cT1-2 squamous cell carcinomas of the oral cavity and oropharynx were prospectively enrolled in this study and were randomized to two treatment arms: in the control arm, a diagnostic panendoscopy with incisional biopsy was followed by a second operation with transoral tumor resection ± neck dissection and tracheostomy. In the intervention arm, patients underwent LBC diagnostics and in case of a positive result received one single operation with panendoscopy and incisional biopsy for confirmation of LBC result by rapid section histology followed by transoral tumor resection ± neck dissection and tracheostomy in the same session. Results Time between clinical diagnosis and definitive surgical treatment was significantly shorter in the intervention group compared with the control group (p < 0.0001). Additionally, time of hospitalization (p < 0.0001) and cumulative operation time (p = 0.062) were shorter in the intervention group. No significant differences in overall, progression-free, and disease-specific survival were observed. Conclusion Cytology-based cancer surgery is a promising therapeutic strategy that can potentially be considered for a well-defined group of early-stage HNSCC patients and help to avoid repetitive general anesthesia, shorten the diagnosis-to-treatment interval and spare operation as well as hospitalization time.

Oral cytological changes in young adults related to alcohol consumption. Arch Oral Biol 2021; 126:105127. [PMID: 33887678 DOI: 10.1016/j.archoralbio.2021.105127] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2021] [Revised: 03/30/2021] [Accepted: 04/14/2021] [Indexed: 12/01/2022]
Abstract
OBJECTIVE The study aimed to investigate the oral cytological changes in young adults with recent history of alcohol consumption, as well as its relation with the consumption of alcohol. DESIGN The sample included 67 young adults, who performed a smear of the oral mucosa and answered a questionnaire about recent and lifetime consumption of alcohol and other drugs. The methods used were sensitive to show the association between alcohol consumption and other drugs with the damage to oral cavity cells. RESULTS DNA fragmentation index, mitochondrial functionality and cell viability, showed a significant difference between alcohol users and nonusers. However, there was no distinction between these parameters and different frequency consumption. Alcohol consumption, economic class and use of illicit drugs were related to the cytological parameters evaluated. CONCLUSIONS This result shows the existence of cell damages among the evaluated students and can direct future studies towards more in-depth investigations of the mechanisms involved.

Head Face Med 2018; 14:9. [PMID: 29843756 PMCID: PMC5975412 DOI: 10.1186/s13005-018-0166-4] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2018] [Accepted: 05/15/2018] [Indexed: 11/10/2022] Open
Abstract
Background Exfoliative cytology performed on oral brush samples can help dentists to decide, whether a given oral lesion is (pre-) malignant. The use of non-invasive brush biopsies as an auxiliary tool in the diagnosis of oral mucosal lesions has gained renewed interest since improvements in cytological techniques such as the development of adjuvant diagnostic tools and liquid-based cell preparation techniques. Methods The aim of this study was to compare the quality of two different preparation techniques (cell collectors): the conventional transfer procedure to glass slides and the so-called liquid-based cytology preparation method. Cell smears were collected from 10 orally healthy individuals (mean age: 24 years) from the palatine mucosa at two different times (baseline and 4 weeks later). Slides of both techniques were stained by Giemsa (n = 40) and May-Gruenwald Giemsa (n = 40). The statistical analysis was performed with Excel. Results On specimen analysis, the liquid-based cytology showed statistically significant improvement compared to conventional glass sides (p < 0.001). Thin layers, which were performed by liquid-based cytology showed significantly better results in the parameters (p < 0.001): uniform distribution, cellular overlapping, cellular disformation, mucus, microbial colonies and debris. The conventional glass slides approach showed more cell overlapping and contamination with extraneous material than thin layers, which were performed by Orcellex® Brush cell collectors. Conclusions Both techniques are diagnostically reliable. The liquid-based method showed an overall improvement on sample preservation, specimen adequacy, visualization of cell morphology and reproducibility. Liquid-based cytology simplifies cell collection due to easier handling and less transfer errors by dentists.
