Hearing Status and Ventilation Tube at Time of Palatoplasty in Cleft Lip and Palate Patients: A Retrospective Study. Medicina (B Aires) 2023; 59:medicina59030513. [PMID: 36984514 PMCID: PMC10055723 DOI: 10.3390/medicina59030513] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2022] [Revised: 02/23/2023] [Accepted: 03/03/2023] [Indexed: 03/08/2023] Open
Abstract
Background and Objectives: There is no consensus regarding the indications for and timing of ventilation tube (VT) insertion in cleft lip and palate (CLP) patients. Our aim was to search for clinical and surgical (i.e., VT insertion) characteristics that influence the hearing status in CLP. Materials and Methods: We reviewed the hearing outcome of consecutive CLP cases operated on at a single referral center. Univariate and multivariate analysis were applied as appropriate. Results: We included 285 consecutive CLP patients, 109 female and 176 male; the mean age at last follow-up was 16.2 years. Unilateral CLP was found in 249 cases and bilateral CLP in 36. Early VTs (i.e., at the time of hard palate surgery) were applied in 75 (26.3%) patients. Late VTs (i.e., after hard palate surgery during follow-up) were applied in 69 (24.2%) children, at a mean age of 6.7 years old. Hearing loss (pure-tone average > 20 dB) was found in 114 (40%) CLP patients at last available follow-up (mild hearing loss in 96 patients, moderate in 18). In univariate and multivariate analyses, we found that only the absence of early VT insertion (p = 0.0003; OR = 18.2) was an independent prognostic factor of hearing loss in CLP patients. Furthermore, when early VTs were not inserted, there was a high risk of late VT (p = 0.002; OR 13.6). Conclusions: According to our results, the absence of VT insertion at the time of hard palate surgery is an independent prognostic risk factor of hearing loss in CLP patients. Early VT placement in CLP patients may prevent hearing loss and related consequences. These findings should be tested in a large, randomized clinical trial.

MEDICINA (KAUNAS, LITHUANIA) 2023; 59:medicina59010161. [PMID: 36676785 PMCID: PMC9864983 DOI: 10.3390/medicina59010161] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/27/2022] [Revised: 01/02/2023] [Accepted: 01/09/2023] [Indexed: 01/15/2023]
Abstract
Background and Objectives: Non-autologous graft materials hold promise for tympanic membrane (TM) perforation closure. In the present manuscript, we aimed to evaluate the influence of clinical and surgical (i.e., graft materials) characteristics on tympanoplasty outcome in chronic otitis media (COM). Materials and Methods: We retrospectively reviewed clinical and surgical characteristics of COM patients with TM perforation treated with tympanoplasty and mastoidectomy. Univariate and multivariate appropriate tests were applied. Results: We used xenograft (porcine submucosal collagen) in 163 patients, and temporalis fascia in 210. The mean follow-up time was 37.2 months. Postoperative TM perforation (i.e., negative outcome) was detected in 11.6% of cases with xenograft, and in 12.8% with temporalis fascia. Performing uni- and multivariate analysis, we determined that large (three or all quadrants) TM perforation (p = 0.04) and moderate-to-severe intraoperative bleeding (p = 0.03) were independent prognostic factors of negative outcome. Considering the 197 patients with moderate-to-severe intraoperative bleeding, we disclosed that the use of temporalis fascia (p = 0.03) was an independent risk factor of postoperative TM perforation. Conclusions: According to our results, large TM perforation and moderate-to-severe intraoperative bleeding were independent prognostic factors of negative outcome in adult COM patients treated with tympanoplasty. In the sub-group of COM patients with excessive intraoperative bleeding, use of temporalis fascia was associated with negative outcome; these patients could benefit from xenograft materials. These findings should be tested in large randomized clinical trials.

Abstract
BACKGROUND Contrast-enhanced ultrasound (CEUS) is considered an attractive imaging technique to evaluate tumor microcirculation. However, the validity of CEUS for assessing laryngeal carcinoma is unclear. PURPOSE To compare the performance of CEUS with conventional US and contrast-enhanced computed tomography (CECT) in the diagnosis and preoperative T-staging of laryngeal carcinoma. MATERIAL AND METHODS Forty-one consecutive patients with laryngeal carcinoma underwent conventional high-frequency US, CEUS, and CECT before surgery. The CEUS characteristics of laryngeal carcinoma were recorded. The imaging findings of CEUS and conventional US were compared with CECT findings and the postoperative pathological examination. RESULTS CEUS showed hyperenhancement in 38 cases and isoenhancement in three cases. Homogeneous distribution of contrast agent was found in 20 cases and heterogeneous distribution in 21 cases, of which 16 cases showed local perfusion defects. In the enhanced phase, rapid entry was observed in 37 cases, synchronous entry was observed in two cases, and slow entry was observed in two cases. Rapid exit was observed in 25 cases and slow exit was observed in 16 cases. The pretherapeutic T-staging accuracy was not significantly different between conventional US, CEUS, and CECT (P ≥ 0.500). A high sensitivity and specificity were achieved by CEUS in the evaluation of involvement of thyroid cartilage. CONCLUSION Compared with conventional US and CECT, CEUS has a reliable initial T-staging accuracy and diagnostic properties for detecting laryngeal cartilage invasion.

Am J Otolaryngol 2020; 41:102455. [PMID: 32475619 DOI: 10.1016/j.amjoto.2020.102455] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/13/2019] [Revised: 03/04/2020] [Accepted: 03/05/2020] [Indexed: 12/23/2022]
Abstract
BACKGROUND There are no reliable outcome predictors for functional dysphonia (FD) patients. OBJECTIVES To investigate if any clinical or phoniatric characteristics could identify FD patients at risk of negative outcome after speech therapy. METHODS We retrospectively reviewed the results of 78 FD patients treated with the proprioceptive elastic method. Before and one-month after therapy, patients underwent endoscopy, acoustic analysis with Multi-Dimensional Voice Program, and Voice Handicap Index-10 questionnaire (VHI-10). Negative outcome was the persistence of VHI-10 ≥ 13. RESULTS 26 FD patients had negative outcome (i.e. VHI-10 ≥ 13) after speech therapy. At univariate analysis, clinical variables (i.e. sex, age, comorbidities, dysphonia duration, and professional voice use) were not associated with the outcome. Elevated Jitter% (Jitt; p = 0.03), Shimmer% (Shim; statistical trend, p = 0.06), and Noise to Harmonics Ratio (statistical trend, p = 0.06) were found in patients with poor results. At multivariate analysis, higher Jitt was an independent negative prognostic factor (p = 0.02), while a statically trend was identified for Shim (p = 0.06). A panel of Jitt >1.5 and Shim >5.1 showed an acceptable discriminatory power (AUC [ROC] = 0.76) according to Hosmer and Lemeshow scale. CONCLUSION A panel of two acoustic analysis parameters could help in identifying FD patients at risk of speech therapy failure. Further studies in these patients are needed to evaluate the most efficient treatment protocol.

Maspin expression and anti-apoptotic pathway regulation by bcl2 in laryngeal cancer. Ann Diagn Pathol 2020; 45:151471. [PMID: 31986422 DOI: 10.1016/j.anndiagpath.2020.151471] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/22/2019] [Revised: 11/25/2019] [Accepted: 01/09/2020] [Indexed: 12/14/2022]
Abstract
OBJECTIVES Comprehension of the interplay of pro-apoptotic and anti-apoptotic stimuli in laryngeal squamous cell carcinoma (LSCC) is crucial to understand tumor development, biological behavior and treatment response. Bcl-2 family proteins mainly regulate the apoptotic signal cascade. In some cancers, maspin seems to influence the balance between pro-apoptosis and anti-apoptosis bcl-2 family proteins. The aim of this study was to investigate the potential relationship between bcl-2 anti-apoptotic factor and the tumor suppressor maspin in LSCC. MATERIALS AND METHODS 31 consecutive patients who underwent primary surgery and post-operative radiotherapy for LSCC were evaluated retrospectively. For each case, immunohistochemistry assays for bcl-2 and maspin were performed. Data were also collected on N-status, pT stage, grading, recurrence and disease-free survival (DFS). RESULTS Patients with nuclear maspin pattern of expression showed a significantly lower recurrence rate (p = 0.04) and longer DFS (p = 0.0018). The expression of bcl-2 was not associated with recurrence rate or DFS either in the whole cohort or in cases with nuclear maspin pattern, while in patients with non-nuclear maspin pattern, a statistical trend was found toward a shorter DFS for bcl-2 positive cases (p = 0.062). In the multivariate model, only maspin expression pattern retained its independent prognostic significance (p = 0.006). CONCLUSIONS Nuclear maspin pattern seemed to be an independent positive prognostic factor, while bcl-2 prognostic value was related to maspin expression pattern. Further investigations are needed to support the use of bcl-2 inhibitors in multimodality or multitarget strategies against advanced LSCCs, also considering the role and expression of tumor suppressor genes.

Abstract
Aim: Positron emission tomography (PET) with 18F-fluordeoxyglucose (18F-FDG) plays an essential role in the staging and tumor monitoring of head and neck squamous cell carcinoma (HNSCC). Microvessel density (MVD) is one of the clinically important histopathological features in HNSCC. The purpose of this study was to analyze possible associations between 18F-FDG-PET findings and MVD parameters in HNSCC. Materials and Methods: Overall, 22 patients with a mean age of 55.2 ± 11.0 and with different HNSCC were acquired. In all cases, whole-body 18F-FDG-PET was performed. For each tumor, the maximum and mean standardized uptake values (SUVmax; SUVmean) were determined. The MVD, including stained vessel area and total number of vessels, was estimated on CD105 stained specimens. All specimens were digitalized and analyzed by using ImageJ software 1.48v. Spearman's correlation coefficient (r) was used to analyze associations between investigated parameters. p-values of <0.05 were taken to indicate statistical significance. Results: SUVmax correlated with vessel area (r = 0.532, p = 0.011) and vessel count (r = 0.434, p = 0.043). Receiver operating characteristic analysis identified a threshold SUVmax of 15 to predict tumors with high MVD with a sensitivity of 72.7% and specificity of 81.8%, with an area under the curve of 82.6%. Conclusion: ⁸F-FDG-PET parameters correlate statistically significantly with MVD in HNSCC. SUVmax may be used for discrimination of tumors with high tumor-related MVD.

Abstract
The present study investigated the expression of non-metastasis 23 (nm 23) in laryngeal cancer tissues and analyzed its correlation with the prognoses of laryngeal cancer patients. A total of 122 laryngeal cancer patients who were admitted to The Affiliated Hospital of Jining Medical College from June 2009 to June 2012, and 30 normal laryngeal mucosal tissues were selected as the control group. Immunohistochemical staining method was used to test the expression of nm 23 in tissues. Quantitative-polymerase chain reaction (q-PCR) and western blotting were conducted to test the expression of nm 23 in tissues at the gene and protein levels, respectively. Moreover, the prognoses of patients were analyzed. The positive expression rate (90.00%) of nm 23 in the normal laryngeal mucosal tissues was markedly higher than that in laryngeal cancer tissues (56.56%) (p<0.05). The expression of nm 23 proteins was correlated with the clinical staging of laryngeal cancer and the metastasis of lymph nodes (p<0.05). The expression of both nm 23 genes and proteins in the laryngeal cancer tissues were significantly lower than those in the normal laryngeal mucosal tissues (p<0.05). The survival rate of the positive nm 23 expression was substantially higher than that of the negative expression with a statistically significant difference (p<0.01). In conclusion, the expression of nm 23 proteins plays an important role in the development and metastasis of laryngeal cancer and may be taken as one of the indicators to evaluate the prognoses of such patients.

Abstract
Laryngeal carcinoma (LC) is one of the most prevalent malignant tumors in the head and neck area. Due to its high morbidity and mortality, LC poses a serious threat to human life and health. Even with surgical removal, some patients were not sensitive to radiotherapy or experienced transfer or recurrence. 20(s)-Protopanaxadiol (PPD), a natural product from Panax ginseng, has been reported to have cytotoxic effects against several cancer cell lines. However, whether it can improve the radiation sensitivity and the underlying mechanism of PPD's sensitization effect is still unknown. Herein, from in vitro and in vivo experiments, we found that the combination of PPD and radiation not only significantly inhibited proliferation and induced apoptosis, but also suppressed the tumor growth in mouse models. These findings confirmed the role of PPD in enhancing the sensitivity of radiotherapy. Moreover, our work showed that the expression levels of mTOR and its downstream effectors decreased remarkably after PPD addition when compared to radiation only. This result suggested that PPD's excellent synergistic effects with radiation might be associated with the down-regulation of the mTOR signaling pathway in Hep-2 cells.

Abstract
Background Endoglin (ENG, CD105), an auxiliary receptor for several TGF-β superfamily ligands, is constitutively expressed in tumor microvessels. The prognostic value of ENG-assessed microvessel density (MVD) has not been systemically analyzed. This meta-analysis reviews and evaluates the association between ENG expression and prognosis in cancer patients. Materials and Methods Thirty published studies involving in 3613 patients were included after searching of PubMed, Web of Science, and EMBASE. The pooled hazard ratios (HRs) and 95% confidence intervals (CIs) for overall survival (OS), disease-free survival (DFS), and cancer-specific survival (CSS) were calculated using random-effects models. The publication bias was detected by a Begg's test and Egger's test. The outcome stability was verified by sensitivity analysis. Results The high ENG-assessed MVD was significantly associated with poor OS (HR = 2.14, 95% CI 1.62-2.81; P < 0.001), DFS (HR = 3.23, 95% CI 2.10-4.95; P < 0.001), CSS (HR = 3.33, 95% CI 1.32-8.37; P < 0.001). Furthermore, subgroup analysis revealed that the association between the overexpression of ENG in tumor microvessels and the outcome endpoints (OS or DFS) were also significant in the Asians and Caucasians patients with different cancer types. Conclusions ENG of tumor microvessels is a predictor of poor OS, DFS and CSS and may be a prognostic marker of patients with cancer.

Abstract
Ion beam therapy has enabled us to treat formerly untreatable malignant tumors. The aim of the present study was to investigate the long-term follow-up course of patients with head and neck cancers who received ion beam therapy. The subjects were 8 patients (3 men and 5 women aged 43-78 years) with head and neck cancers who visited our department from 2006 to 2015 and received ion beam therapy. Six patients received carbon ion beam therapy, and the other two patients received proton beam therapy. The medical records of the patients were retrospectively analyzed. The primary site was the nasal and paranasal sinuses in six cases, nasopharynx in one case, and external auditory canal in one case. The histological type was olfactory neuroblastoma, malignant melanoma, and adenoid cystic carcinoma in two cases each, and chondrosarcoma and squamous cell carcinoma in one case each. The exposure dose ranged from 64 to 70.4 GyE. The average follow-up period was 42.0 months. Early adverse events were generally mild, and complete therapeutic response was obtained in all cases. However, five patients developed severe late complications including craniospinal dissemination, osteoradionecrosis of the maxilla and skull base, brain necrosis, and loss of eyesight. Three patients died of distant metastasis, local recurrence and/or brain necrosis within 2 years, and four patients have been surviving with distant metastasis or severe late complications. Ion beam therapy exhibits outstanding antitumor effects, but the severe late complications of the therapy must also be recognized.

Abstract
INTRODUCTION The excision repair cross-complementation group 2 (ERCC2) ATP-dependent helicase is an essential member of the DNA repair pathway. It has been observed to be differentially expressed in different cancers, which shows its involvement in carcinogenesis. AIM In the present study we have tried to determine the association of expression patterns of this gene with head and neck carcinogenesis. METHOD We first carried out a systematic review of the available studies on the role of ERCC2 in head and neck cancer (HNC). In order to test the hypothesis that the expression patterns of XPD/ERCC2 play a critical role in HNC pathogenesis, we then conducted a population based case-control study on 81 head and neck tumor samples and adjacent normal-tissue control samples. Reverse transcriptase polymerase chain reaction (RT-PCR) and quantitative polymerase chain reaction (qPCR) were used to assess ERCC2 deregulation at the mRNA level. RESULT Expression analysis showed that the ERCC2 expression level was significantly upregulated (p<0.05) in HNC tissues compared with adjacent normal tissues. Furthermore, the expression pattern of ERCC2 was correlated with the expression pattern of Ki-67 and a significant correlation (r = 0.230, p<0.03) was observed between ERCC2 and Ki-67. Spearman's correlation also showed a significant correlation between ERCC2 expression and tumor stage (r = 0.271, p<0.02) and grade (r = 0.228, p<0.02) of HNC. CONCLUSIONS Our data suggest that deregulation of ERCC2 in HNC has the potential to predict a more aggressive cancer phenotype and may be considered a possible biomarker for improved diagnosis and prognosis of HNC.

J Clin Pathol 2015; 69:415-21.

Abstract
BACKGROUND Laryngeal verrucous squamous cell carcinoma (VSCC) is a highly differentiated squamous cell carcinoma (SCC), the diagnosis of which can meet with many pitfalls: benign hyperplastic lesions and conventional SCC are the most important differential diagnoses. The microRNA miR-19a is overexpressed in many solid tumours and regulates the suppressor of cytokine signalling-1 (SOCS-1) expression. AIMS The main endpoints were to assess miR-19a and SOCS-1 expression in glottic VSCC, and the former's potential role in differentiating between glottic VSCC, conventional SCC and hyperplastic lesions. METHODS The expression of MiR-19a (by reverse transcription and quantitative real-time PCR) and SOCS-1 (by immunohistochemistry, rabbit polyclonal anti-SOCS-1 antibody) was assessed in 11 consecutive cases of glottic VSCC, 20 of papillary hyperplasia and 42 cases of conventional SCC. RESULTS Mean miR-19a expression was significantly higher (p = 0.000) in malignant glottic lesions (conventional SCC/VSCC) than in benign conditions. Significant differences in mean miR-19a expression also emerged between conventional SCC and papillary hyperplasia (p = 0.000), and between conventional SCC and VSCC (p = 0.03). miR-19a expression was not statistically associated with SOCS-1 immunoreactivity or immunostaining intensity in VSCC, conventional SCC or papillary hyperplasia. CONCLUSIONS Our preliminary outcomes suggest the utility of miR-19a in the challenging differential diagnosis of laryngeal VSCC. Although miR-19a has been found to regulate SOCS-1 expression, this evidence was not confirmed by this investigation.

Abstract
Malignant pleural mesothelioma (MPM) is a rare cancer originated from pleural mesothelial cells. MPM has been associated with long-term exposure to asbestos. The prognosis of MPM is poor due to the difficulty of making diagnosis in the early stage, the rapid progression, the high invasiveness and the lack of effective treatment. Although the incidence of MPM is low in China to date, it has a tendency to increase in the coming years. The variety of clinical features may cause the delay of diagnosis and high rate of misdiagnosis. The diagnosis of MPM is based on biopsy of the pleura and immunohistochemistry. As China has become the largest country in the consumption of asbestos, it would give rise to a new surge of MPM in the future. The current treatment of MPM is multimodality therapy including surgery, radiotherapy, chemotherapy and immunotherapy. Two surgical procedures are commonly applied: extrapleural pneumonectomy (EPP) and pleurectomy/decortication (P/D). Three dimensional conformal radiotherapy is used to denote a spectrum of radiation planning and delivery techniques that rely on the 3D imaging to define the tumor. Cisplatin combined with pemetrexed (PEM) is the first-line chemotherapy for MPM. The principal targets in immunotherapy include T cells (Treg), CTLA-4 and PD-1. The diagnosis, treatment and prognosis still remain a major challenge for clinical research and will do so for years to come.

Can a panel of clinical, laboratory, and pathological variables pinpoint patients with sinonasal polyposis at higher risk of recurrence after surgery? Am J Otolaryngol 2015; 36:554-8. [PMID: 25702570 DOI: 10.1016/j.amjoto.2015.01.019] [Citation(s) in RCA: 42] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/21/2015] [Accepted: 01/27/2015] [Indexed: 12/22/2022]
Abstract
PURPOSE Despite improved surgical and medical therapies, recurrence remains a significant problem in chronic rhinosinusitis with nasal polyps (CRSwNP), given a recently-reported long-term revision rate of 15%-20%. In this prospective study uni- and multivariate statistical analyses were used to identify clinical, laboratory and conventional pathological parameters for pinpointing CRSwNP patients at higher risk of recurrence after functional endoscopic sinus surgery (FESS). MATERIALS AND METHODS The investigation concerned 179 consecutive patients undergoing FESS for CRSwNP, and 24 of them developed recurrent CRSwNP after FESS. RESULTS A univariate statistical model disclosed significant associations between recurrent CRSwNP and serum basophil counts (p=0.03) and percentages (p=0.02). The recurrence rate was higher for patients with eosinophilic-type CRSwNP (p=0.01). In a multivariate logistic model, eosinophilic-type CRSwNP (p=0.025) and serum basophil percentage (statistical trend, p=0.079) retained their independent prognostic significance in relation to CRSwNP recurrence. The discriminatory power of a three-variable panel (age <65 years, serum basophil percentage and eosinophilic type) featured an AUC (ROC) of 0.7028 (an acceptable discriminatory power according to the Hosmer-Lemeshow scale). CONCLUSIONS Although our panel achieved an acceptable discriminatory power for CRSwNP recurrence, other parameters (including biomarkers) capable of predicting outcome and orienting postoperative treatment decisions need to be investigated in CRSwNP.
