Impact of Adjuvant Radiotherapy in Squamous Cell Carcinoma of the Oral Cavity with Perineural Invasion. Laryngoscope 2024; 134:2019-2027. [PMID: 37975480 DOI: 10.1002/lary.31148] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2023] [Revised: 10/07/2023] [Accepted: 10/13/2023] [Indexed: 11/19/2023]
Abstract
OBJECTIVE Current guidelines indicate postoperative radiotherapy (PORT) in oral squamous cell carcinoma (OSCC) with perineural invasion (PNI), however, its real benefit has never been proven. The aim of our study is to investigate the benefit of PORT in OSCC patients with PNI in terms of survival and disease control. DATA SOURCES The Pubmed/MEDLINE, Cochrane Library, and Scopus databases. REVIEW METHODS Patients with PNI + OSCC treated with primary surgery were extracted from the included studies. The pooled logHR was calculated by comparing patients who underwent PORT to those who underwent only observation for overall survival (OS), disease-specific survival (DSS), disease-free survival (DFS), and locoregional control (LRC). RESULTS About 690 patients with primary OSCC and PNI were included from nine studies. 374 (54.2%) patients underwent PORT, while 316 (45.8%) underwent observation. Analyses showed non-significant difference between the two groups for OS (HR: 1.01; 95% CI: 0.38-2.69), DSS (HR: 2.03; 95% CI: 0.54-7.56), and LRC (HR: 0.89; 95% CI: 0.53-1.50). They showed a significant difference in terms of DFS (HR: 0.86; 95% CI: 0.77-0.97). CONCLUSION The real benefit of PORT in OSCC patients with PNI is still unclear, although it may have a positive impact on DFS. Clinicians should consider individual patient's characteristics, tumor factors, and treatment goals when deciding whether to recommend PORT. Further studies are needed to clarify which entity of PNI really benefits from PORT. LEVEL OF EVIDENCE NA Laryngoscope, 134:2019-2027, 2024.

Procalcitonin for Early Detection of Pharyngocutaneous Fistula after Total Laryngectomy: A Pilot Study. Cancers (Basel) 2024; 16:768. [PMID: 38398159 PMCID: PMC10886710 DOI: 10.3390/cancers16040768] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2023] [Revised: 02/06/2024] [Accepted: 02/08/2024] [Indexed: 02/25/2024] Open
Abstract
OBJECTIVES The aim of this prospective study was to investigate the role of procalcitonin as an early diagnostic marker of pharyngocutaneous fistula (PCF) in a cohort of head and neck patients treated with total laryngectomy for squamous cell carcinoma. METHODS This prospective study was conducted on a sample of patients enrolled from January 2019 to March 2022. All patients were subjected to a "protocol" of blood chemistry investigations, scheduled as follows: complete blood count with formula, ESR dosage, CPR, and PCT. PCT was also dosed by salivary sampling and a pharyngo-cutaneous swab in patients who presented with PCF. The dosage scheme was systematically repeated: the day before the intervention (t0); the 5th day postoperative (t1); the 20th day postoperative (t2); and at time X, the day of the eventual appearance of the pharyngocutaneous fistula. RESULTS A total of 36 patients met the inclusion criteria. The patients enrolled in the study were subsequently divided into two groups: 27 patients underwent total laryngectomy (TL) for laryngeal cancer without postoperative complications, and 9 patients were undergoing TL with postoperative PCF. Using the Cochran's Q test, statistical significance was found for PCT among T0, T1, Tx, and T2 (p-value < 0.001) between the PCF and non-PCF groups. The Z test demonstrated that there is a difference in PCT levels at T1 and T2 and that this difference is statistically significant (p < 0.001). CONCLUSIONS PCT could be considered an early marker of complications in open laryngeal surgery. According to our results, it could be useful in the precocious detection of pharyngocutaneous fistulas and in the management of antibiotic therapy.

A Retrospective Multicenter Italian Analysis of Epidemiological, Clinical and Histopathological Features in a Sample of Patients with Acinic Cell Carcinoma of the Parotid Gland. Cancers (Basel) 2023; 15:5456. [PMID: 38001716 PMCID: PMC10669973 DOI: 10.3390/cancers15225456] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/02/2023] [Revised: 11/04/2023] [Accepted: 11/14/2023] [Indexed: 11/26/2023] Open
Abstract
BACKGROUND The acinic cell carcinoma (AciCC) of the parotid gland is a rare tumor with an indolent behavior; however, a subgroup of this tumor presents an aggressive behavior with a tendency to recur. The aim of this multicenter study was to identify and stratify those patients with AciCC at high risk of tumor recurrence. METHODS A retrospective study was carried out involving 77 patients treated with surgery between January 2000 and September 2022, in different Italian referral centers. Data about tumor characteristics and its recurrence were collected. The histological specimens and slides were independently reviewed by a senior pathologist coordinator (L.C.) and the institution's local head and neck pathologist. RESULTS The patients' age average was 53.6 years, with a female prevalence in the group. The mean follow-up was 67.4 months (1-258, SD 59.39). The five-year overall survival (OS) was 83.2%. The 5-year disease-free survival (DFS) was 60% (95% CI 58.2-61.7). A high incidence of necrosis, extraglandular spread, lymphovascular invasion (LVI), atypical mitosis, and cellular pleomorphism was observed in the high-risk tumors compared to the low-risk ones. CONCLUSION AciCC generally had an indolent behavior, optimal OS, DFS with few cervical node metastases, and rare distant relapses. This multicenter retrospective case series provides evidence of the need for clinical-epidemiological-histological stratification for patients at risk of poor outcomes. Our results suggest that the correct definition of high-risk AciCC should include tumor size, the presence of necrosis, extraglandular spread, LVI, atypical mitosis, and cellular pleomorphism.

Abstract
OBJECTIVE The aim of this study was to assess the long-term effectiveness of quantic molecular resonance (QMR) in the treatment of inferior turbinate hypertrophy (ITH) in allergic and nonallergic rhinitis refractory to medical therapy. METHODS This study enrolled 281 patients, 160 males (56.9%) and 121 females (43.1%), mean age 37.8 ± 4.1 years, range 18 to 71. Fifty-four patients have been lost to follow up and have been therefore excluded from the final analysis. Based on skin prick test results, 69 patients were considered allergic (group A) and 158 nonallergic (group B). All subjects underwent before surgery (T0) and 3 (T1), 12 (T2), 24 (T3), and 36 months (T4) after QMR treatment to: 4-phase rhinomanometric examination, nasal endoscopy evaluation, and visual analogue scale to quantify the subjective feelings about nasal obstruction. RESULTS Subjective and objective parameters showed statistically significant improvement in both groups. Group B parameters not changed during follow-up, while group A showed significant worsening between T1 and subsequent assessments. T4 outcome indicates a better result in nonallergic patients. CONCLUSIONS In accordance with the literature, our preliminary data validate QMR treatment as a successful therapeutic option for nasal obstruction due to ITH. Nonallergic patients had a very good T4 outcome. Allergic patients showed a worsening trend after 1 year probably due to other causes.

Abstract
Relapsing polychondritis (RP) is a rare systemic disease that is characterized by recurrent episodic inflammation of the cartilaginous structures of the body, resulting in their progressive destruction and subsequent replacement with fibrotic scar. We present a case of RP that initially manifested with subglottic involvement and we propose an innovative strategy for the treatment for laryngeal RP in phase of active inflammation. A multidisciplinary approach (rheumatologist, otolaryngologist, immunologist, internist, cardiologist, etc) and adequate follow-up are essential. The timeliness of the diagnosis is fundamental to contain the destructive effects on the cartilages involved.

Trans oral robotic surgery for oropharyngeal cancer: A multi institutional experience. EUROPEAN JOURNAL OF SURGICAL ONCOLOGY 2023; 49:106945. [PMID: 37331862 DOI: 10.1016/j.ejso.2023.05.020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/11/2023] [Revised: 05/23/2023] [Accepted: 05/30/2023] [Indexed: 06/20/2023]
Abstract
OBJECTIVES Trans Oral Robotic Surgery (TORS) has proved to be a safe and feasible treatment for oropharyngeal squamous cell carcinoma (OPSCC). The aim of this study is to analyse oncological outcomes of OPSCC patients treated with TORS. MATERIALS AND METHODS This study involved 139 patients with OPSCC, treated with TORS between 2008 and 2020. Clinicopathological characteristics, treatment details and oncological outcomes were evaluated retrospectively. RESULTS The management strategies included TORS alone in 42.5%, TORS-RT in 25.2% and TORS-CRT in 30.9%. The ENE was noted in 28.8% of neck dissections. In 19 patients clinically classified as unknown primaries, the primary was found in 73.7%. Rates of local, regional relapses and distant metastasis were 8.6%, 7.2%, and 6.5%, respectively. The 5 year- Overall Survival and Disease Free Survival were 69.6% and 71.3%, respectively. CONCLUSION TORS fits well in the modern management of OPSCC. Although definitive CRT remains a milestone, TORS is proving to be a valid and safe treatment option. The choice of the therapeutic strategy requires evaluation by a multidisciplinary team.

Submandibular gland involvement in oral cavity squamous cell carcinoma: a retrospective multicenter study. Eur Arch Otorhinolaryngol 2023; 280:4205-4214. [PMID: 37280380 PMCID: PMC10382344 DOI: 10.1007/s00405-023-08007-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2022] [Accepted: 05/05/2023] [Indexed: 06/08/2023]
Abstract
BACKGROUND The submandibular gland (SMG) is routinely excised during neck dissection. Given the importance of the SMG in saliva production, it is important to understand its involvement rate by cancer tissue and the feasibility of its preservation. METHODS Retrospective data were collected from five academic centers in Europe. The study involved adult patients affected by primary oral cavity carcinoma (OCC) undergoing tumor excision and neck dissection. The main outcome analyzed was the SMG involvement rate. A systematic review and a meta-analysis were also conducted to provide an updated synthesis of the topic. RESULTS A total of 642 patients were enrolled. The SMG involvement rate was 12/642 (1.9%; 95% CI 1.0-3.2) when considered per patient, and 12/852 (1.4%; 95% CI 0.6-2.1) when considered per gland. All the glands involved were ipsilateral to the tumor. Statistical analysis showed that predictive factors for gland invasion were: advanced pT status, advanced nodal involvement, presence of extracapsular spread and perivascular invasion. The involvement of level I lymph nodes was associated with gland invasion in 9 out of 12 cases. pN0 cases were correlated with a reduced risk of SMG involvement. The review of the literature and the meta-analysis confirmed the rare involvement of the SMG: on the 4458 patients and 5037 glands analyzed, the involvement rate was 1.8% (99% CI 1.1-2.7) and 1.6% (99% CI 1.0-2.4), respectively. CONCLUSIONS The incidence of SMG involvement in primary OCC is rare. Therefore, exploring gland preservation as an option in selected cases would be reasonable. Future prospective studies are needed to investigate the oncological safety and the real impact on quality of life of SMG preservation.

Abstract
BACKGROUND AND AIM Free flaps or pedicle flaps are the mainstay of cancer surgery in the head and neck area. However, their long-term sequelae are still poorly understood. Among these, the development of a secondary primary tumor on a flap is a rare and uncertain reported event. Methods: A computer-aided systematic literature search was performed by using the PubMed, EMBASE and Cochrane Library databases. A systematic review of the literature, following the PRISMA checklist, was carried out with the aim of analyzing all the citations reporting this second primary, with attention to risk factors, behavior, etiological causes. Results: Overall, 27 cases of second primary squamous cell carcinoma arising on a pedicle or free flap were identified. In addition, other three cases were discussed. Conclusions: Persistent exposure to oral stimuli such saliva, oral microbiome, smoke or a colonization by the adjacent mucosa were considered as a possible cause of second primary carcinoma. Although rare, a new neoplasm onset should know and considered as a new concept in the follow-up of patients undergoing reconstruction with free or pedicle flaps.

Abstract
BACKGROUND Laryngeal carcinoma (LC) remains a significant economic and emotional problem to the healthcare system and severe social morbidity. New tools as Machine Learning could allow clinicians to develop accurate and reproducible treatments. METHODS This study aims to evaluate the performance of a ML-algorithm in predicting 1- and 3-year overall survival (OS) in a cohort of patients surgical treated for LC. Moreover, the impact of different adverse features on prognosis will be investigated. Data was collected on oncological FU of 132 patients. A retrospective review was performed to create a dataset of 23 variables for each patient. RESULTS The decision-tree algorithm is highly effective in predicting the prognosis, with a 95% accuracy in predicting the 1-year survival and 82.5% in 3-year survival; The measured AUC area is 0.886 at 1-year Test and 0.871 at 3-years Test. The measured AUC area is 0.917 at 1-year Training set and 0.964 at 3-years Training set. Factors that affected 1yOS are: LNR, type of surgery, and subsite. The most significant variables at 3yOS are: number of metastasis, perineural invasion and Grading. CONCLUSIONS The integration of ML in medical practices could revolutionize our approach on cancer pathology.

Abstract
BACKGROUND Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. METHODS This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low-middle-income countries. RESULTS In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of 'single-use' consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low-middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. CONCLUSION This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high- and low-middle-income countries.

Abstract
BACKGROUND To retrospectively evaluate oncological outcomes in two groups of patients with pT4aN0 glottic SCC treated with total laryngectomy (TL) and neck dissection (ND) who underwent postoperative radiotherapy or exclusive clinical and radiological follow-up. METHODS It includes patients with pT4N0 glottic SCC who underwent TL and unilateral or bilateral ND with or without PORT. Divided in two comparison groups: the first group underwent adjuvant RT (TL-PORT); the second group referred to clinical and radiological follow-up (TL). RESULTS PORT was associated with a better OS while no differences were found in terms of DSS. A better local control is achieved when PORT is administered while no differences in terms of regional and distant control rates were found. Bilateral ND positively impacts on the regional control while the PNI negatively impact the regional control. CONCLUSIONS A tailored PORT protocol might be considered for pT4N0 glottic SCC treated with TL and ND, both considering the ND's extent and presence of PNI.

Abstract
OBJECTIVE To determine the oncological outcomes of salvage transoral laser microsurgery (TLM) in the treatment of patients suffering from recurrent laryngeal cancer. METHODS PubMed/MEDLINE, Cochrane Library, and Scopus databases were searched. English language, original studies investigating oncological outcomes of TLM in adult patients with recurrent laryngeal cancer were included. Data were pooled using a distribution-free approach for estimating summary local control (LC), disease-specific survival (DSS), and overall survival (OS) curves with random effects. RESULTS Two hundred and thirty-five patients underwent salvage TLM after primary (chemo)radiotherapy. The mean follow-up time was 60.8 months (95% CI: 32.7-88.9). Estimated pooled LC rates (95% CI) at 1, 3 and 5 years were 74.2% (61.7-89.4), 53.9% (38.5-75.3), and 39.1% (25.2-60.8). Estimated pooled DSS rates (95% CI) at 1, 3 and 5 years were 88.4% (82.0-95.3), 67.8% (50.9-90.3), and 58.9% (42.7-81.1). Two hundred and seventy-one patients underwent TLM after primary laser treatment. The mean follow-up time was 70.9 months (95% CI: 36.9-104.9). Estimated pooled LC rates (95% CI) at 1, 3 and 5 years were 72.2% (64.7-80.6), 53.2% (42.2-66.9), and 40.4% (29.6-55.2). Estimated pooled DSS rates (95% CI) at 1, 3 and 5 years were 92.1% (85.5-99.1), 77.0% (64.4-92.0), and 67.1% (51.6-87.3). CONCLUSIONS TLM is a valuable treatment option for the management of locally recurrent laryngeal carcinoma if performed by experienced surgeons and following rigorous patients' selection criteria. Further studies should be conducted to define stage-based clinical guidelines. LEVEL OF EVIDENCE NA Laryngoscope, 133:1425-1433, 2023.

Abstract
OBJECTIVES To analyze the demographic data, surgical and adjuvant treatment data and the survival outcomes in adult patients affected by acinic cell carcinoma of the parotid gland (AciCC). METHODS A retrospective multicenter analysis of patients treated for AciCC of the parotid gland from 2000 to 2021 was performed. Exclusion criteria were pediatric (0-18 years) patients, the absence of follow-up and patients with secondary metastatic disease to the parotid gland. Multivariable logistic regression was used to determine factors associated with survival. RESULTS The study included 81 adult patients with AciCC of the parotid gland. The median age was 46.3 years (SD 15.81, range 19-84 years), with a gender female prevalence (F = 48, M = 33). The mean follow-up was 77.7 months (min 4-max 361, SD 72.46). The 5 years overall survival (OS) was 97.5%. The 5 years disease-free survival (DFS) was 60%. No statistical differences have been found in prognosis for age (< 65 or ≥ 65 years), sex, surgery type (superficial vs profound parotid surgery), radicality (R0 vs R1 + Rclose), neck dissection, early pathologic T and N stages and adjuvant therapy (p > 0.05). CONCLUSION This study did not find prognostic factor for poorest outcome. In contrast with the existing literature, our results showed how also high-grade tumours cannot be considered predictive of recurrence or aggressive behaviour.

Abstract
PURPOSE Retro-auricular approach using an autologous graft is the main surgical method for myringoplasty (MPL). Endaural and transcanal or endoscopic approaches are also used. There is no definitive consensus on the best MPL surgical technique. The aim of this study is to compare the two most used technique, over and underlay MPL, to evaluate the difference in anatomical and functional outcomes. MATERIALS AND METHODS We made a retrospective analysis of 497 adult patients who underwent underlay or overlay primary MPL, between 2010 and 2018, and evaluated the difference in anatomical and functional outcomes. RESULTS Successful functional results, evaluated 18 months after surgery, were obtained in 380 patients (76,4%); the underlay MPL obtained a successful result in 85% of patients, while the overlay technique in the 68%. We observed anatomical failure in 13.4% patients, in detail 9,8% of underlay MPL and 17,2% of overlay MPL had an anatomical failure. CONCLUSION Our results show less complications related to the underlay technique. We believe that this remains the technique to prefer, except in subtotal or wide anterior perforations that could be better managed using the overlay technique.

Anomaly of digastric muscle: an alarm bell for head and neck surgeon. ACTA BIO-MEDICA : ATENEI PARMENSIS 2021; 92:e2021262. [PMID: 34747390 PMCID: PMC10523038 DOI: 10.23750/abm.v92is1.11843] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Subscribe] [Scholar Register] [Received: 05/27/2021] [Accepted: 05/30/2021] [Indexed: 11/23/2022]
Abstract
Objectives: Here follows the discussion of a case of hypoplasia of both bellies of digastric muscle and the difficult during neck dissection, because of his surgical importance like a pivotal landmark. METHODS We reported a case report concerning digastric muscle abnormalities, accidentally discovered during neck dissection due to surgical excision of a glottic squamous cell carcinoma staged as cT3N0. A brief literature review was done to compare and research similar cases. RESULTS Literature counts several reports of digastric muscle abnormalities, namely involving the anterior belly. Little has been written about hypoplasia of digastric muscle. CONCLUSION Digastric muscle abnormalities are rare, which can be absent or, more frequently, duplicated. Albeit its anomalies are anecdotal, it is advisable to give due consideration to the hypoplasia of both bellies of the digastric muscle during the analysis of radiological imaging, in order to prevent the risk of operative complications. According to our knowledge, this is the first and singular case of digastric muscle's hypoplasia.

Antibody Persistence 6 Months Post-Vaccination with BNT162b2 among Health Care Workers. Vaccines (Basel) 2021; 9:vaccines9101125. [PMID: 34696233 PMCID: PMC8538824 DOI: 10.3390/vaccines9101125] [Citation(s) in RCA: 24] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2021] [Revised: 09/17/2021] [Accepted: 09/24/2021] [Indexed: 01/16/2023] Open
Abstract
BACKGROUND We present immunogenicity data 6 months after the first dose of BNT162b2 in correlation with age, gender, BMI, comorbidities and previous SARS-CoV-2 infection. METHODS An immunogenicity evaluation was carried out among health care workers (HCW) vaccinated at the Istituti Fisioterapici Ospitalieri (IFO). All HCW were asked to be vaccine by the national vaccine campaign at the beginning of 2021. Serum samples were collected on day 1 just prior to the first dose of the vaccine and on day 21 just prior to the second vaccination dose. Thereafter sera samples were collected 28, 49, 84 and 168 days after the first dose of BNT162b2. Quantitative measurement of IgG antibodies against S1/S2 antigens of SARS-CoV-2 was performed with a commercial chemiluminescent immunoassay. RESULTS Two hundred seventy-four HWCs were analyzed, 175 women (63.9%) and 99 men (36.1%). The maximum antibody geometric mean concentration (AbGMC) was reached at T2 (299.89 AU/mL; 95% CI: 263.53-339.52) with a significant increase compared to baseline (p < 0.0001). Thereafter, a progressive decrease was observed. At T5, a median decrease of 59.6% in COVID-19 negative, and of 67.8% in COVID-19 positive individuals were identified with respect to the highest antibody response. At T1, age and previous COVID-19 were associated with differences in antibody response, while at T2 and T3 differences in immune response were associated with age, gender and previous COVID-19. At T4 and T5, only COVID-19 positive participants demonstrated a greater antibody response, whereas no other variables seemed to influence antibody levels. CONCLUSIONS Overall our study clearly shows antibody persistence at 6 months, albeit with a certain decline. Thus, the use of this vaccine in addressing the COVID-19 pandemic is supported by our results that in turn open debate about the need for further boosts.

Lymphoepithelial carcinoma of larynx and hypopharynx: a systematic review and pooled analysis. Eur Arch Otorhinolaryngol 2021; 279:1157-1166. [PMID: 34338877 DOI: 10.1007/s00405-021-07011-0] [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: 05/25/2021] [Accepted: 07/20/2021] [Indexed: 12/12/2022]
Abstract
PURPOSE To define the oncologic outcomes and the prognostic factors of laryngeal and hypopharyngeal lymphoepithelial carcinoma (LEC). METHODS A systematic review and individual patient data analysis were performed according to the PRISMA guidelines. A total of 41 patients (males: 37; mean age: 63.1, standard deviation: 10.0) were included. RESULTS The median follow-up time was 36.0 months (interquartile range, IQR: 11.5-73.5), while the median overall survival (OS) time was 96 months (IQR: 39.0-120.0). Estimated disease-specific survival (DSS) rates (95% Confidence Interval, CI; number still at risk) at 1, 3, and 5 years were 94.4% (79.5-98.6; 31), 82.7% (62.7-92.5; 21), and 78.1% (56.8-89.7; 13), respectively. Estimated disease-free survival (DFS) rates (95% CI; number still at risk) at 1, 3, and 5 years were 92.1% (77.4-97.4; 31), 74.9% (55.6-86.8; 21), and 66.6% (46.1-80.8; 13), respectively. Patients undergoing primary surgery had a reduced chance of death from cancer than patients receiving primary radiotherapy (5-year DSS 85.6 vs. 56.2%; p = 0.04), while EBV positivity tend to be a negative prognostic factor (5-year DSS 100 vs. 66.7%; p = 0.05). CONCLUSIONS Laryngeal and hypopharyngeal LEC is a rare disease with favorable survival. Further prospective multicenter studies are needed to make a reliable statement on prognosis and outcome, stratifying patients for different therapy regimens and tumor stages.

Cell-Free Human Papillomavirus-DNA for Monitoring Treatment Response of Head and Neck Squamous Cell Carcinoma: Systematic Review and Meta-Analysis. Laryngoscope 2021; 132:560-568. [PMID: 34236084 DOI: 10.1002/lary.29739] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2021] [Revised: 06/22/2021] [Accepted: 06/26/2021] [Indexed: 11/09/2022]
Abstract
OBJECTIVES/HYPOTHESIS The aim of this study was to assess the value of cell-free human papillomavirus-DNA (cfHPV-DNA) as a diagnostic test for the post-treatment surveillance of patients with HPV-positive head and neck squamous cell carcinoma (HNSCC) through a systematic review and meta-analysis. STUDY DESIGN Systematic review and meta-analysis. METHODS A literature search was conducted in three databases (MEDLINE, Embase, and Scopus) in January 2021. The population included patients with HPV-positive HNSCC. The intervention was the use of the repeated liquid biopsy with circulating HPV-DNA detection during follow-up. The outcome was to establish the value of cfHPV-DNA as a diagnostic test for the post-treatment surveillance of patients with HPV-positive HNSCC. RESULTS Ten studies included in the meta-analysis provided a total of 457 patients with HPV-positive HNSCC. The meta-analytic study estimated the diagnostic performance of cfHPV-DNA as follows: pooled sensitivity and specificity of 0.65 (95% confidence interval [CI]: 0.40-0.84) and 0.99 (99% CI: 0.96-0.99), respectively; positive and negative likelihood ratios of 62.5 (99% CI: 22.9-170.2) and 0.05 (99% CI: 0.013-0.24), respectively; and pooled diagnostic odds ratio of 371.66 (99% CI: 60.4-2286.7). CONCLUSION Currently, the follow-up protocol for HNSCC patients includes routine clinical evaluation and radiological imaging. Biomarkers to monitor this disease are not established. Considering its high specificity, cfHPV-DNA represents a potential confirmatory test in the case of positive positron emission tomography and computed tomography. In the near future, cfHPV-DNA could be used as a biomarker for monitoring the treatment response during the clinical trials of de-escalation therapy or immunotherapy. Larger sample sizes and the homologation of study protocols and methodology are needed to better establish its utility in the clinical practice. Laryngoscope, 2021.

Initial observations on age, gender, BMI and hypertension in antibody responses to SARS-CoV-2 BNT162b2 vaccine. EClinicalMedicine 2021; 36:100928. [PMID: 34109307 PMCID: PMC8177433 DOI: 10.1016/j.eclinm.2021.100928] [Citation(s) in RCA: 108] [Impact Index Per Article: 36.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/23/2021] [Revised: 04/28/2021] [Accepted: 05/10/2021] [Indexed: 12/11/2022] Open
Abstract
BACKGROUND Literature data suggests that age, gender and body mass index (BMI) could be associated with difference in immune responses to vaccines. The first goal of the study was to analyze the antibody titre seven days after the second dose of BNT162b2 vaccine in a group of 248 healthcare workers (HCWs). The second goal was to analyze how antibody titre changes in correlation with age, gender, BMI and hypertension. METHODS An immunogenicity evaluation was carried out among HCWs vaccinated at the Istituti Fisioterapici Ospitalieri (IFO), Rome, Italy. All HCWs were asked to be vaccinated by the Italian national vaccine campaign at the beginning of 2021. 260 vaccinated HCWs were enrolled in the study. All eligible participants were assigned to receive the priming dose in two weeks' time and the booster dose exactly 21 days thereafter. Blood and nasopharyngeal swabs were collected at baseline and 7 days after second dose of vaccine. Quantitative measurements of IgG antibodies against S1/S2 antigens of SARS-CoV-2 were performed with a commercial chemiluminescent immunoassay. Presence of SARS-Cov-2 in nasopharyngeal swab was determined by commercial RT-PCR testing. FINDINGS 248 HWCs were analyzed, 158 women (63.7%) and 90 men (36.3%). After the second dose of BNT162b2 vaccine, 99.5% of participants developed a humoral immune response. The geometric mean concentration of antibodies among the vaccinated subjects after booster dose (285.9 AU/mL 95% CI: 249.5-327.7) was higher than that of human convalescent sera (39.4 AU/mL, 95% CI: 33.1-46.9), with p<0.0001. Multivariate linear regression analysis of AU/mL by age, gender and BMI multivariate was performed by the inclusion of covariates. This analysis demonstrated that age (p<0.0001) and gender (p = 0.038) are statistically associated with differences in antibody response after vaccination, whereas BMI and hypertension have no statistically significant association (p = 0.078 and p = 0.52 respectively). INTERPRETATION 99.5% of HCW developed a humoral immune response and female and young participants seem to have an increased capacity to mount humoral immune responses. BMI and hypertension seem not associated with difference in immune response to the vaccine. FUNDING None.

Abstract
PURPOSE To evaluate the functional and oncologic outcomes of adjuvant (chemo)radiation [(C)RT] after open partial horizontal laryngectomies (OPHLs). METHODS Multicenter retrospective evaluation of 130 patients (116 males, 14 females) submitted between 1995 and 2017 to OPHL Types II and III for laryngeal cancer and receiving adjuvant (C)RT for one or more of the following risk factors at histopathologic examination of the surgical specimen: pT4a and/or > pN2a categories, close/positive resection margins, or presence of both perineural (PNI) and lympho-vascular invasion (LVI). The primary study endpoints were evaluation of the presence of tracheostomy and/or gastrostomy at last follow-up, and calculation of laryngo-esophageal dysfunction-free survival (LEDFS). RESULTS Mean age of the study cohort was 60.8 ± 8.9 years (median, 62; interquartile range [IQR], 13). Mean follow-up was 50.7 ± 39.4 months (range 24-188; median, 38; IQR, 51). Adjuvant therapy consisted of CRT in 53 (41%) patients, and RT alone in 77 (59%). Five-year LEDFS was 85%. Overall survival was 71.5%, while 13% of patients remained tracheostomy- and 3% gastrostomy-dependent at the last follow-up. The only significant variable in predicting survival (p = 0.020) was tracheostomy dependence: it was maintained in 7.5% of subjects after OPHL Type II and in 34% of those submitted to OHPL Type III (p < 0.001). CONCLUSIONS In selected patients affected by advanced laryngeal cancer, OPHLs Type II and III have a relatively good laryngeal safety profile and provide favorable oncologic outcomes even in case of need for adjuvant (C)RT.

Abstract
OBJECTIVE/HYPOTHESIS To define the best surgical technique able to reduce Frey syndrome (FS) incidence after parotidectomy. STUDY DESIGN Systematic review and network meta-analysis. METHODS An arm-based network analysis was conducted using a Bayesian hierarchical model. The primary and secondary outcomes were the incidence of subjective (clinical) and objective (positive starch-iodine test result) FS, respectively. RESULTS A total of 3830 patients with a median age of 50.35 years (n = 2323; IQR 44.25-54.18) were included for six interventions [temporoparietal fascia (TPFF), free fat graft (FFG), acellular dermal matrix (ADM), sternocleidomastoid muscle (SCM) flap, and superficial musculoaponeurotic system (SMAS) flap]. If compared to no treatment, the greatest reduction of subjective (clinical) FS incidence was measured for the TPFF (OR: 0.07, CI: 0.004-0.57), the ADM (OR: 0.09, CI: 0.02-0.35), and the FFG (OR: 0.11, CI: 0.03-0.42) techniques. However, a significant difference was measured also for the SCM flap (OR: 0.38, CI: 0.18-0.73) and for the SMAS flap (OR: 0.42, CI: 0.19-0.97). All treatments showed a significant reduction of the objective FS incidence if compared to no treatment (FFG, OR: 0.06, CI: 0.002-0.62; TPFF, OR: 0.07, CI: 0.01-0.33; ADM, OR: 0.11, CI: 0.03-0.44; SMAS, OR: 0.36, CI: 0.17-0.71; SCM, OR: 0.40, CI: 0.19-0.74). CONCLUSIONS TPFF, ADM, and FFG seem to be the best treatment strategies to prevent FS after parotidectomy. Further randomized controlled trials comparing these techniques should be conducted to define specific indications. Laryngoscope, 131:1761-1768, 2021.

Abstract
BACKGROUND AND AIM Lipoma is a benign mesenchymal tumor. It is a very common tumor and in 13% of cases occurs in head and neck. Giant lipomas are extraordinary and cervical involvement with mediastinal extension is an exceedingly rare presentation. Only a few cases of thoracic extension are reported in literature. METHODS We describe the case of a 62-years-old man with a giant cervico-mediastinic lipoma which required a combined approach through cervicotomy and sternotomy to ensure surgical radicality. Differential diagnoses could be thymolipoma, liposarcoma or familiar lipomatosis. RESULTS The mass was removed en-bloc with thymus and locoregional lymph nodes. The patient recovered uneventfully. CONCLUSIONS The aim of this report is to discuss potential pitfalls of differential diagnosis and implementation of the therapeutic treatment. Focus on the relevance of performing fluorescence in situ hybridization (FISH) for MDM2 amplification is reported, a necessary technique for the differential diagnosis. (www.actabiomedica.it).

Temporoparietal Fascia Flap Endonasal Transposition in Skull Base Reconstruction: Surgical Technique. World Neurosurg 2020; 146:118. [PMID: 33166688 DOI: 10.1016/j.wneu.2020.10.169] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2020] [Revised: 10/29/2020] [Accepted: 10/30/2020] [Indexed: 11/17/2022]
Abstract
Reconstruction of wide skull base defects resulting from multimodal treatment of cranial base malignancies are challenging.1 Endonasal pedicled flaps (e.g., Hadad-Bassagusteguy flap)1,2 are generally the first choice; however, inadequacy for the size and location of the defect or their unavailability are common occurrences in salvage reconstructions, and prior irradiation is an additional unfavorable condition for local flap viability. The temporoparietal fascia flap (TPFF)3 is a regional flap vascularized by the superficial temporal artery, which is able to survive and integrate even in postirradiated areas. Its properties, such as thinness, pliability, foldability, and the long pedicle, make it a versatile flap for reconstruction of various defects of the skull base, both in adults3-7 and children.8 In lateral skull surgery, TPFF proved to be effective in patients at higher risk of cerebrospinal fluid leak,7 whereas its transposition into the nasal cavity through a temporal-infratemporal tunnel has been widely reported to repair defects of the ventral skull base.3-6 It represents a safe and effective technique with minimal additional morbidity (potential alopecia or scalp necrosis).4,5 A recently described modification of this technique supports TPFF transposition via a supraorbital epidural corridor to reach the anterior skull base, especially for large defects with supraorbital extension.6 The present video (Video 1) shows the step-by-step TPFF harvesting and endonasal transposition via a temporal-infratemporal tunnel to repair a wide middle cranial fossa defect resulting from osteoradionecrosis after endoscopic resection and heavy-particle radiation therapy for sinonasal adenoid-cystic carcinoma. At 6-months follow-up, optimal healing without complications was observed.

Abstract
INTRODUCTION Fine-needle aspiration cytology (FNAC) is a basic step in the diagnosis of salivary gland tumors that have a wide variety of histological types. The recent Milan system for reporting salivary gland cytopathology (MSRSGC) can correlate the risk of malignancy with precise cytological features. A revised version was recently proposed to improve the surgical relevance and facilitate uniform management. MATERIAL AND METHODS A multicenter study retrospectively used the original and revised MSRSGC criteria to classify a series of patients who received surgery after FNAC. RESULTS We enrolled 503 patients from three tertiary centers. The risk of malignancy for the MSRSGC resulted 19.5% in cat. I, 14.3% in cat. II, 17.6% in cat. III, 3.6% in cat. IVa, 24.6% in cat. IVb, 66.7% in cat. V, and 96.8% in cat. VI. The results from the revised MSRSGC were consistent with the original values. CONCLUSION The MSRSGC is a promising classification system. In our opinion, the revised version of the MSRSGC supplements FNAC with some crucial clinical information and can better identify the appropriate treatment in each category.

Abstract
OBJECTIVES Recently, Lymph Node Yield (LNY) and Lymph Node Ratio (LNR) have emerged as prognostic indicators in head and neck cancer. However, there is a lack of data regarding the LNY and LNR values in the specific neck levels dissected and regarding the factors that influence these values. MATERIALS AND METHODS Preliminary results of the NCT03534778 trial are reported. LNY and LNR values were estimated for 100 patients with oral or oropharynx carcinoma, from November 1, 2018 to September 30, 2019. RESULTS Overall, the mean number of lymph nodes retrieved was 34.4 (95% confidence interval [CI] 31.6-37.3). LNY means and CI per single neck level were as follows: level I 5.5 lymph nodes harvested (95% CI 3.5-7.5), level II 15.4 (95% CI 10.6-20.2), level III 8.0 (95% CI 4.6-11.3), level IV 6.3 (95% CI 3.4-9.15), level V 6.3 (95% CI 3.6-9.0). cN+ patients had a higher number of lymph nodes retrieved, odds ratio (OR) 1.2 (95% CI 1.05-1.36). Smokers had less lymph nodes harvested, OR 0.78 (95% CI, 0.71-0.87). Mean LNR was 0.063 (95% CI 0.047-0.078). A multiple regression analysis showed that anatomic site, pN, smoking status and LNY statistically significantly predicted the LNR (p < 0.05) CONCLUSIONS: The LNY and LNR values are influenced by various demographic and pathological characteristics of the patient, such as the number of dissected levels, primary site, cN positivity, and smoking status.

Abstract
Performing a proper nasal and oropharyngeal swab procedure is essential in the screening of COVID-19 infection. The video illustration of nasal and oropharyngeal swab is presented (Video S1). To correctly perform the nasopharyngeal swab, the patient must be seated comfortably with the back of their head against the headrest. The swab is inserted in the nose horizontally, along an imaginary line between the nostril and the ear. Oropharyngeal sampling is easier to perform. The swab is directed toward the rear wall of the oropharynx and it is rotated a few times before removal. After taking the sample, it is necessary to insert both swabs in the same tube, breaking the rod with one swift and controlled movement. Finally, carefully reset the cap. It appears to be extremely important to properly collect nasopharyngeal and oropharyngeal swabs in order to minimize the false negative rate among COVID-19 positive patients.

Abstract
Amyloidosis is a group of idiopathic clinical syndromes caused by the deposition of insoluble fibrillar proteins (amyloid) in the extracellular matrix of organs and tissues. These deposits disrupt the function of the target organ. Amyloidosis can manifest as a systemic disease or a single-organ involvement (local form). Its etiology still remains unclear. Deposits of amyloid in the larynx are rare, accounting for between 0.2 and 1.2% of benign tumors of the larynx. In this retrospective study, we report the clinical aspects, diagnosis, treatment and follow-up of five female patients with localized laryngeal amyloidosis without systemic involvement. The patients were all treated successfully using microlaryngoscopy with CO2 laser or cold instruments. Prognosis is excellent; however, appropriate follow-up is an important part of the long-term management of this disease in order to prevent and control the possibility of local recurrence.
