The impact of the tumor immune microenvironment and tumor-infiltrating lymphocyte subgroups on laryngeal cancer prognosis.

The absence of improvement in survival rates across various cancers, including laryngeal cancer, has led to an increasing interest in understanding the immune response to cancer. In head and neck cancers, immune modulatory mechanisms such as immune microenvironment and immune infiltration are important in cancer pathogenesis. This study aims to explore the distribution of tumor-infiltrating lymphocyte (TIL) subgroups in the immune microenvironment and evaluate their impact on tumor histopathological characteristics and prognosis. The study included 50 patients who underwent laryngectomy for laryngeal squamous cell carcinoma, in Istanbul University - Cerrahpasa, Faculty of Medicine Department of Otorhinolaryngology, between January 2016 and January 2018. Pathology specimens were evaluated using immunohistochemistry to assess the expressions of the CD3, CD20, CD8, CD4, CD25, and FoxP3 markers, identifying subgroups of TILs. The investigation aimed to uncover how these subgroups influence tumor histopathological features and survival outcomes. The high infiltration of CD3, CD20, and CD4 had a positive impact on disease-specific survival, disease-free survival, and recurrence-free survival. In addition, overall survival was positively affected by high CD3 and CD4 infiltrations. However, no significant relationship was observed between the expressions of CD8, FoxP3, and CD25 and any of the survival parameters. The infiltration of CD3, CD20, and CD4 positive cells indicative of a robust antitumoral immune response-emerged as favorable prognostic factors in laryngeal cancer. These findings suggest that enhancing the infiltration of CD3, CD20, and CD4 lymphocytes could be a therapeutic strategy worth exploring in clinical trials.

Perivascular Epitheloid Cell Tumor (PEComa) of the Neck.

Perivascular epitheloid cell tumors (PEComas) are a family of neoplasms with distinctive perivascular epitheloid cells. 36 year old female patient admitted to our clinic with a mass on neck. Biopsy was reported as PEComa. PEComas are very rare, especially in neck region. Here, we present the second case in literature.

Long-term efficacy of tonsillectomy/adenotonsillectomy in patients with periodic fever aphthous stomatitis pharyngitis adenitis syndrome with special emphasis on co-existence of familial Mediterranean fever.

Periodic fever, aphthous stomatitis, pharyngitis, adenitis (PFAPA) syndrome is one of the most common autoinflammatory fever disorders in the childhood which may co-exists with familial Mediterranean fever (FMF) causing treatment complexity. As the role of surgery in PFAPA syndrome is still controversial, in this paper, our aim is to present our results of tonsillectomy/adenotonsillectomy in the treatment of PFAPA syndrome. Archives of a tertiary care hospital were investigated for patients who underwent tonsillectomy or adenotonsillectomy due to PFAPA Syndrome between 2010 and 2020. 344 patients were found but only 281 of them were accessible. Through phone call interview and chart review methods, preoperative and postoperative the number and severity of the attacks and general satisfaction after the operation were recorded and analyzed. Also, patients with concomitant FMF were analyzed separately. A total of 281 patients were included in the study. There was no improvement in 10 (3.55%) patients. Eight (2.84%) patients showed mild improvement, 29 (10.32%) patients had moderate improvement and 234 (83.27%) patients had full recovery after tonsillectomy. There were 266 PFAPA patients without FMF. No improvement, mild improvement, moderate improvement, and full recovery in this patient group were 5 (1.9%), 6 (2.3%), 25 (9.4%) and 230 (86.5%), respectively. FMF was present in 5.33% (15/281) of the patients. In PFAPA + FMF group 5 patients had no improvement (33.3%), 2 had mild improvement (13.3%), 4 had moderate improvement (26.7%) and 4 had full recovery (26.7%). Benefit of tonsillectomy was significantly lower in the patients with concomitant FMF when compared to the patients who did not have FMF (p < 0.001). Age of diagnosis, age of operation, severity of the disease, type of operation, and gender were found to have no significant relationship with the benefit from surgery (p < 0.05). According to the findings of this study, tonsillectomy is an effective long-term treatment for PFAPA syndrome with success rate of 83.27%. Also, preoperatively FMF should be considered in these patients, which dramatically reduces surgical efficacy.

The Role of Preemptive Infiltration Anesthesia in the Management of Postoperative Pain Following Septoplasty.

Introduction Septoplasty is one of the most common surgical procedures in rhinology practice. Two major problems encountered after septoplasty are pain and bleeding. Preoperative administration of analgesics before the surgical stimulus, which is the main concept of preemptive analgesia, decreases postoperative pain. Objective The present study was designed to investigate whether preincisional lidocaine infiltration to the subperichondrial area during septoplasty surgery reduced or not postoperative pain and analgesic use. Methods The present prospective, randomized, placebo controlled, double-blind trial was conducted on 64 consecutive patients with nasal septum deviation. Patients were randomly divided into 2 groups; the study group received 2% 20 mg lidocaine/cc ( n = 31), and the control group received 6 cc 0.9% NaCl ( n = 33). A standard questionnaire was given to each patient to mark his or her pain score between 0 and 10 at the 1 st , 3 rd , 6 th , 12 th , and 24 th hours. Results The mean and the range of visual analogue scale (VAS) scores of the patients in the study group at the 1 st , 3 rd , 12 th , and 24 th hours were 4.03 ± 3.08 (0-10); 3.42 ± 2.39 (0-8); 2.97 ± 2.22 (0-8); 2.87 ± 2.61 (0-9); and 1.94 ± 2.06 (0-9) respectively. The mean and the range of VAS scores of the patients in the control group at the 1 st , 3 rd , 12 th , and 24 th hours were 4.12 ± 2.7 (0-10); 3.45 ± 2.4 (0-10); 2.94 ± 2.7 (0-10); 2.79 ± 2.34 (0-10); and 1.5 ± 1.8 (0-6), respectively. The statistical analysis revealed no significant difference among the groups. Conclusion The preemptive local anesthetic administration to the incision area and under the mucoperichondrial flap before septoplasty does not decrease the level of postoperative pain.

Is Preoperative Embolization Necessary for Carotid Paraganglioma Resection: Experience of a Tertiary Center.

PURPOSE: This study was designed to investigate whether preoperative embolization is a useful procedure to decrease blood loss and neurovascular complications for carotid body tumor (CBT) surgery or not. METHODS: Medical records of our tertiary care center from 2012 to 2019 were scanned for patients who underwent surgery for CBT, retrospectively. Age, gender, complaint and head and neck examination findings at the time of presentation, preoperative complete blood count parameters, imaging records (cervical magnetic resonance imaging and carotid artery angiography), Shamblin classification, tumor size, intraoperative findings, and postoperative complications were noted. RESULTS: A total of 26 patients were operated due to CBT between 2012 and 2019 in our clinic; preoperative arterial embolization was performed to 15 (57.7%) patients, and 11 (42.3%) patients were operated without embolization. Youngest patient was 24 years old, while oldest was 69 years and mean age was 44.35 ± 12.73. (embolization group: ages ranging between 24 and 64 with a mean of 41.5 ± 11.02 years; in nonembolization group: ages ranging between 26 and 69 with a mean of 48.1 ± 14.3). Embolization status was not significantly related to cranial nerve injury, vascular injury, overall complications, and hematocrit decrease. Arterial injury is more likely to occur with increasing Shamblin class (r = .39; P = .04). Tumor size is not found to be significantly related to cranial nerve injury, vascular injury, overall complications, and hematocrit decrease, but cranial nerve injury and vascular injury were more likely to occur in large tumors (r = .34; P = .089 and r = .34; P = .087, respectively). Age was significantly and negatively correlated to vascular injury (r = -.51; P = .05). Vascular injury was significantly correlated with gender (male predominance: r = -.64; P = .000). CONCLUSION: Although preoperative arterial embolization is considered to attenuate the complication risk, we found that there was no significant difference among the patients with or without embolization.

Delayed presentation of head and neck cancer patients during COVID-19 pandemic.

PURPOSE: Impact of COVID-19 pandemic on healthcare is huge. We intended to demonstrate how COVID-19 pandemic affected primary head and neck oncology patient's referral and admission to a tertiary center by comparing the retrospective patient data in March-September 2020 and the same period in 2019. METHODS: In this cross-sectional study, from March 15th, 2020 to September 15th, 2020, medical records of 61 patients (Group 1) diagnosed and scheduled for surgery for head and neck cancer in our tertiary care center were revised and compared with 64 head and neck cancer patients treated in the same institution in the same time period of the previous year (Group2). Surgical site, TNM stages, need for reconstruction with flap, time from first symptom occurrence to first admission to our institution, and time to surgery were noted. RESULTS: In Group 1, out of 56 patients, 26 were diagnosed with T1-2 tumor, while 30 had T3-4 tumor. In Group 2, 43 of 60 patients had T1-2 tumor, while only 17 of them were diagnosed with T3-4 tumor. The rate of T3-4 tumors had significantly increased in 2020 when compared to 2019 (p = 0.049). In oral cavity cancer patients, N stage was significantly increased in Group 1 when compared to Group 2 (p = 0.024). Need for reconstruction with regional or free flaps were significantly increased in oral cavity cancer patients (p = 0,022). The mean time from the beginning of the first symptom to the admission was 19.01 ± 4.6 weeks (ranging between 11 and 32 weeks) in Group 1, while it was 16.6 ± 5.9 weeks in Group 2 (ranging between 6 and18 weeks); with significant increase (p = 0,02). The time to surgery from first admission was 3.4 ± 2.5 and 2.9 ± 1.2 weeks in Group 1 and 2, respectively, with no statistically significant difference (p = 0.06). CONCLUSION: The COVID-19 pandemic has caused delay in the diagnosis and treatment of many diseases as such in head and neck cancers. Admission with advanced stage disease and the need for more complex reconstructive procedures were increased. During the pandemic, the management of other diseases that cause mortality and morbidity should not be neglected and priorities should be determined.

Evaluation of Olfactory Function With Objective Tests in COVID-19-Positive Patients: A Cross-Sectional Study.

OBJECTIVE: Olfactory dysfunction is relatively high in coronavirus disease 2019 (COVID-19) patients. The aim of this study is to investigate the incidence of olfactory disorder objectively in patients with laboratory-confirmed COVID-19 infection. MATERIAL AND METHOD: The study included 31 healthy controls and 59 COVID-19 patients who were diagnosed and treated in the COVID departments in a tertiary hospital. The patients with corona virus infection were screened by a questionnaire and were classified into 2 groups as either group 2 (patients without self-reported smell loss) or group 3 (patients with self-reported smell loss). Age and gender matched healthy controls who do not have chronic nasal condition or nasal surgery history comprised the control group (group 1). All of the patients and subjects in the control group were tested by the Sniffin' Sticks test. All of the answers and scores were recorded, and the comparisons were made. RESULTS: The rate of self-reported smell and taste loss in all COVID-19 patients in this study was 52.5% and 42%, respectively. There was a significant difference in threshold, discrimination, identification, and Threshold, Discrimination, Identification (TDI) scores between groups 1 and 2. When the comparisons between group 1 and 3 were made, again threshold, discrimination, identification, and TDI scores were significantly different. The comparison between groups 2 and 3 demonstrated a significant difference in discrimination, identification, and TDI scores, but threshold score was not different statistically. With questionnaire, the rate of olfactory dysfunction in COVID-19 patients was 52.5%, but with objective test, the rate was calculated as 83%. CONCLUSION: Olfactory and gustatory dysfunctions are common in COVID-19 patients. According to findings with the objective test method in this study, smell disorder in COVID-19 patients was much higher than those detected by questionnaires.

Extra-Cochlear Insertion in Cochlear Implantation: A Potentially Disastrous Condition.

OBJECTIVES: Cochlear implantation is an increasingly used technique for auditory rehabilitation of pediatric and adult population. Safe implantation is achieved in most cases; however, intraoperative complications and misplacement of the electrode are observed in some. The aim of this presentation was to review the characteristics of patients with extra-cochlear electrode insertion, postoperative diagnostic methods, and considerations in revision surgery. MATERIALS AND METHODS: In total, 423 cases of cochlear implantation performed in our clinic between 2012 and 2018 were retrospectively analyzed and those of extra-cochlear implantation were evaluated. RESULTS: Extra-cochlear insertion was found in 3 patients. The electrode was placed into the internal acoustic canal in the first case, superior semicircular canal in the second case, and internal carotid artery canal in the third case. Cochlear insertion was achieved in all cases with re-implantation, and no complication was observed. CONCLUSION: This case series highlights that rare, but potentially serious, consequences of misplacement of the electrode in cochlear implantation can be successfully avoided and treated via a multidisciplinary approach.
