Therapeutic flexible airway endoscopy of small children in a tertiary referral center-11 years' experience.

ABSTRACT:

Objectives

Use of therapeutic flexible airway endoscopy (TFAE) is very limited in pediatrics. We report our clinical experiences and long term outcomes of TFAE in small children from a single tertiary referral center.

Methods

This is a retrospective cohort study. Small children with their body weight no more than 5.0 kg who had received TFAE between 2005 and 2015 were enrolled. Demographic information and outcomes were reviewed and analyzed from medical charts and TFAE videos.

Results

A total of 313 TFAE were performed in 225 children. The mean age was 3.50 ± 0.24 (0.01-19.2) months old; the mean body weight was 3.52 ± 0.65 (0.57-5.0) kg. A noninvasive ventilation technique, without mask or artificial airway, was applied to support all the procedures. TFAE included laser therapy (39.6%), balloon dilatation plasty (25.6%), tracheal intubation (24.3%) and metallic stent placement (6.4%). Short-length endoscopes of 30-35 cm were used in 96%. All TFAE were successfully completed without serious adverse events or mortality. Mean procedural time was 27.6 ± 16.1 minutes. TFAE resulted in successful extubation immediately in 67.2% (45/67) and 62.8% (118/188) were able to wean off their positive pressure ventilation support in 7 days after procedures. By the end of this study, these TFAE averted the originally suggested airway surgeries in 93.8% (61/65), as benefited from laser therapy, stent implantation, and balloon dilatation plasty.

Conclusions

The TFAE modality of using short-length endoscopes as supported with this noninvasive ventilation and ICU support is a viable, instant and effective management in small children. It has resulted in rapid weaning of respiratory supports and averted more invasive rigid endoscopy or airway surgeries.

Project description:BACKGROUND:There has been a sharp rise in the incidence of human papillomavirus (HPV) associated oropharyngeal squamous cell carcinoma (OPSCC) in many countries. Patients with HPV-positive OPSCC have a more favorable prognosis compared with HPV-negative OPSCC, leading to investigation and adoption of de-escalation treatment protocols. The baseline rate of HPV prevalence in certain populations is of epidemiologic significance. We aimed to evaluate the rate of high-risk HPV in a large cohort of Thai patients, including OPSCC, oral SCC (OSCC) and laryngeal SCC (LSCC). METHODS:In total, 504 patients with HN cancer (110 OPSCC, 260 OSCC and 134 LSCC) who had been treated in Chulalongkorn University between 2010 and 2016 formed the sample set. All histological slides were reviewed to validate the diagnosis and render the histological type as keratinizing (K), non-keratinizing (NK) or non-keratinizing with maturation (NK-M). Immunohistochemistry with p16 was performed in all cases and scored semiquantatively. Positive and equivocal cases were tested by the high-risk HPV DNA in situ hybridization (ISH). Validation with quantitative polymerase-chain reaction (qPCR) was performed in p16-positive OPSCC. RESULTS:The OPSCC were represented by NK (7.3%), NK-M (16.4%) and K (76.4%) types, with an HPV incidence of 100, 22.2 and 4.7%, respectively. The average HPV prevalence in OPSCC was 14.5%. The concordance with p16/ISH was 51.6%, while concordance of the NK morphology with positive HPV ISH was 100%. ISH-qPCR concordance in p16-positive OPSCC was 72.7%. Patients with HPV-positive OPSCC had significantly more tumors with a NK histologic type, tonsillar location, earlier clinical stage, less association with smoking, and, finally, better outcome and longer survival time. In non-OPSCC, p16-positive HPV-associated cancers were found in only 1.5% of OSCC (4/260) and LSCC (2/134). CONCLUSION:A low rate of HPV-related OPSCC was found in Thai patients. The NK morphology was an excellent predictor of high-risk HPV infection in OPSCC. For OPSCC patients, HPV-positive ones had a significantly longer survival time than HPV-negative ones. There was a lack of p16-positive HPV-related OSCC and LSCC. Morphology and p16 status had a poor predictive value for detecting HPV in OSCC and LSCC.
