Effect of Individualized Nutrition Intervention Care Combined with Swallowing Training on Postoperative Nutritional Status in Patients with Laryngeal Cancer

Introduction: Laryngeal carcinoma accounts for 13.9% of head and neck tumors, and squamous cell carcinoma is the main pathological type. At present, the treatment of laryngeal cancer is mainly surgical treatment or postoperative radiotherapy. The surgery is delicate, complex, time-consuming and traumatic. Postoperative patients are prone to dysphagia, leading to an increase in the incidence of malnutrition. Malnutrition can cause a series of negative effects, including weight loss, increased incidence of infection, reduced tolerance of anti-tumor treatment, and extended length of hospital stay. Therefore, how to effectively improve the nutritional status of laryngeal cancer patients through nursing intervention has become an important topic of nursing research. Objective: Investigate the effect of individualized nutrition intervention care combined with swallowing training on postoperative nutritional status in patients with laryngeal cancer. Methods: A total of 120 consecutive patients who underwent laryngeal surgery at our hospital for the first time between May 2018 and May 2021 were selected for the study and equally divided into the control group and the study group by the random number table method, with 60 patients in each group. Patients in the control group were given swallowing function training and health counseling, and the study group adopted individualized nutrition intervention care based on the control group. The nutritional status, swallowing function, and quality of life (QOL) of the patients were assessed using the Patient-generated Subjective Global Assessment (PG-SGA), MD Anderson Dysphagia Inventory (MDADI), and Quality of Life Questionnaire-Core30 (QLQ-C30) before the intervention and three months after the intervention. Results: Before the intervention, the scores of MDADI, PG-SGA, and QLQ-C30 were not significantly different between the two groups (P > 0.05), and three months after the intervention, the scores of MDADI and QLQ-C30 increased and the score of PG-SGA decreased in the study group, with significant differences (P 0.05). At three months after the intervention, patients in the study group had higher scores on MDADI, QLQ-C30 and lower scores on PG-SGA than the control group, with significant differences (P Conclusion: Combining individualized nutrition intervention care with swallowing training improves the postoperative nutritional status, swallowing function, and QOL of patients with laryngeal cancer.

Laryngeal Cancers at the Pathological Anatomical Laboratory (ACP) in Dakar about 215 Cases

Introduction: Laryngeal cancer is the first cancer of upper aerodigestive tract. Dysphonia, dyspnea and dysphagia are evocative signs. Diagnosis is histological and squamous cell carcinoma is the most common type. The objective of our study was to discuss epidemiological and anatomo-pathological characteristics of laryngeal cancers diagnosed in different pathological anatomy and cytology (ACP) laboratories of Dakar hospitals. Material and method: This was a retrospective study spanning from January 2013 to December 2018 at the pathological anatomy laboratories of Fann, Aristide Le Dantec and Idrissa Pouye hospitals. All patients with laryngeal cancer confirmed at histology were included. Data collection was based on clinical records of the patients and archives of histological reports of the pathological laboratories. Data analysis was performed under the Excel software. Results: We collected 215 cases of laryngeal cancer. The average age was 58.01 years with extremes of 07 and 94 years. The male sex was predominant with 183 patients (85.12%) against 32 women (14.88%). The most noted risk factor was tobacco which affected 14 patients, or 60.87%. Three patients (13.04%) did not present any alcohol-smoking impregnation. Clinically, dysphonia was noted in 22 patients (26.51%). It was associated with dyspnea in 0.48% of cases and dysphagia in 3.61%. Laryngoscopy was performed in 62 patients or 28.83% of cases, nasofibroscopy in 6.45% of cases. Cord arythenoid fixity was noted in two patients (3.23%) and hypo-mobility in 1 patient (1.61%). The most frequent local extension was involvement of the piriform sinus with 11.29% of cases. Palpable lymphadenopathy reported in 17 patients (20.48%). Pathological examination was performed in all patients after post endoscopic biopsy in 92 patients (42.79%), and after obtaining the operative specimen in 123 cases (57.21%). The three floors affected 76 patients (35.35%). The ulcerative budding aspect most noted concerned 108 patients (60.97%). Histologically, it was a squamous cell carcinoma in 205 patients (95.34%). The most site invaded by the tumor was cricoid cartilage.T4 type was most found (45 patients or 40.90%) followed by the T3 type with 34.55%. There was no lymphadenopathy invasion (Type N0) in 74 patients (67.27%), capsular rupture was reported in five patients (6.77%), no evaluable metastasis in 110 patients (97.27%), and stage IVA predominated in 66 patients (60%). Conclusion: laryngeal cancer is a reality in our contexts, however, its incidence is poorly understood in Senegal. The main risk factors remain tobacco and alcohol. Histology confirms the diagnosis. Its management is multidisciplinary and must be early.

Incidence and mortality of laryngeal cancer in China, 2011

Objective： Laryngeal cancer is the common cancer of the upper aerodigestive tract. We aimed to use the national cancer registration data in 2011 to estimate the incidence and mortality of laryngeal cancer within China. Methods： Comparable, high-quality data from 177 population-based cancer registries were qualified for analysis. The pooled data were stratified by area, sex and age group. National new cases and deaths of laryngeal cancer were estimated using age-specific rates and national population in 2010. All incidence and death rates were age-standardized to the 2000 Chinese standard population and Segi＇s population, which were expressed per 100,000 populations. Results： All 177 cancer registries covered a total of 175,310,169 population （98,341,507 in urban and 76,968,662 in rural areas）, accounting for 13.01% of the national population. The data quality indicators of proportion of morphological verification （MV%）, percentage of cancer cases identified with death certification only （DCO%） and mortality to incidence ratio （Mr/） were 77.98%, 2.62% and 0.55, respectively. Estimated 20,875 new cases of laryngeal cancer were diagnosed and 11,488 deaths from laryngeal cancer occurred in China in 2011. The crude incidence rate of laryngeal cancer was 1.55/100,000 （2.69/100,000 in males and 0.35/100,000 in females）. Age-standardized incidence rates by Chinese standard population （ASIRC） and by world standard population （ASIRW） were 1.13/100,000 and 1.14/100,000, respectively. Laryngeal cancer is much rarer in females than in males. The incidence rate was higher in urban areas than that in rural areas. The crude mortality rate of laryngeal cancer was 0.85/100,000 （1.42/100,000 in males and 0.25/100,000 in females）. Age-standardized mortality rates by Chinese standard population （ASMRC） and by world standard population （ASMRW） were both 0.61/100,000. The mortality rate in males was much higher than that in females. There was no definite difference in mortality rates of laryngeal cancer between urban and rural areas. Conclusions： Larynx is a specialized area and cancer of larynx significantly affects the quality of life for the patients. Comprehensive measures should be carried out to prevent the ascent of laryngeal cancer.

Incidence and mortality of laryngeal cancer in China,2008–2012

Objective：To analyze the incidence and mortality rates of laryngeal cancer in China from 2008 to 2012.Methods：Incident and death cases of laryngeal cancer were retrieved from the National Central Cancer Registry（NCCR）database collecting from 135 cancer registries in China during 2008–2012.The crude incidence and mortality rates of laryngeal cancer were calculated by area（urban/rural）,region（eastern,middle,western）,gender and age group（0,1–4,5–9,…,85＋）.China census in 2000 and Segi’s world population were applied for age standardized rates.Join Point（Version 4.5.0.1）model was used for time trend analysis.Results：The crude incidence rate of laryngeal cancer was 1.86/100,000 ranked the 21st in overall cancers.The age-standardized incidence rates by China population（ASIRC）and by World population（ASIRW）were1.22/100,000 and 1.23/100,000,respectively.The crude mortality of laryngeal cancer in China was 1.01/100,000and it was the 21st cause of cancer-related death in overall cancers.Both the age-standardized mortality rates by Chinese standard population（ASMRC）and by world standard population（ASMRW）were 0.63/100,000.Incidence and mortality rates of laryngeal cancer were higher in males than in females and higher in urban areas than in rural areas.Middle areas had the highest incidence and mortality rates followed by eastern and western areas.Incidence and mortality rates of laryngeal cancer retained low level before age of 40 years old but increased greatly after and peaked in age group of 75.Incidence showed significant down trends in recent 10 years by 1.27%annually[95%confidence interval（95%CI）：–2.2%,–0.3%].Mortality declined in females sharply by 5.18%per year although stable in males and both sexes combined.Conclusions：Appropriate targeted prevention,early detection and treatment programs should be carried out to control the local burden of laryngeal cancer.

ABO blood group is a predictor of survival in patients with laryngeal cancer

Background: Whether the ABO blood group is associated with the survival of patients with laryngeal cancer remains unknown. The purpose of this study was to investigate the association between the ABO blood group and clinico?pathologic characteristics of patients with laryngeal cancer and assess whether the ABO blood group was associated with prognosis.Methods: We analyzed the records of 1260 patients with laryngeal cancer who underwent curative treatment at Sun Yat?sen University Cancer Center between January 1993 and December 2009. The Chi?square test was used to assess the relationship between the ABO blood group and clinicopathologic characteristics. The Kaplan–Meier method was used to estimate 3?, 5?, and 10?year overall survival(OS) rates. The Cox proportional hazards model was used in univariate and multivariate analyses of OS.Results: No signiicant association was found between the ABO blood group and clinicopathologic characteristics except for primary tumor site. The median OS for patients with blood groups A, B, AB, and O were 87.0, 80.0, 90.0, and 72.5 months, respectively. The 3?, 5?, and 10?year OS rates were 82.4%, 76.0%, and 67.5% for patients with blood group A; 77.4%, 69.8%, and 58.4% for patients with blood group B; 82.2%, 73.1%, and 65.6% for patients with blood group AB; and 71.7%, 66.4%, and 55.5% for patients with blood group O, respectively. Univariate and multivariate analyses showed that the ABO blood group had signiicant efects on prognosis in patients with laryngeal cancer.Conclusions: The ABO blood group is associated with survival in patients with laryngeal cancer. Patients with blood group O had signiicantly shorter OS than patients with other ABO blood groups.

GROWTH INHIBITION OF HUMAN LARYNGEAL CANCER CELL WITH THE ADENOVIRUS-MEDIATED p53 GENE

Objective: In most laryngeal cancers, the function of p53 gene is down regulated. To explore the potential use of p53 in gene therapy of laryngeal cancer, by introducing wild-type p53 into laryngeal cancer cell line via a recombinant adenoviral vector, Ad5CMV-p53 and analyzing its effects on cell and tumor growth. Methods: A human laryngeal cancer, cell line Hep-2 was used. Recombinant cytomegalovirus-promoted adenoviruses containing human wild-type p53 cDNA was transiently introduced into Hep-2 line. The growth suppression of the Hep-2 cells and established s.c. squamous, carcinoma model was examined. The p53 protein expression was detected using immunohistochemical analysis. Results: The transduction efficiencies of Hep-2 cell line were 100% at a multiplicity of 100 or greater. The p53 protein expression peaked on day 2 after infection and lasted far 5 days. In vitro growth assays revealed cell death following Ad5CMV-p53 infected. In vivo studies, Ad5CMV-p53 inhibited the tumorigenicity of Hep-2 cell, and in nude mice with established s.c. squamous, carcinoma, nodules showed that tumor volumes were significantly reduced in mice that received peritumoral infiltration of Ad5CMV-p53. Conclusion: Adenovirus-mediated antitumor therapy carrying the p53 gene is an efficient method to inhibit laryngeal cancer growth. Transfection of laryngeal cancer cells with the wild-type p53 gene via Ad5CMV-p53 is a potential novel approach to the therapy of laryngeal cancer.

Effects of RFTVR and CO2 laser on symptoms improvement, QOL and vas of patients with early laryngeal cancer

Objective: To study the effect of RFTVR and CO2 laser on the improvement of symptoms, QOL and vas of patients with early laryngeal cancer. Methods: In this study, 120 patients with laryngeal cancer diagnosed and treated from January 2015 to December 2016 were taken as research objects. All patients were randomly divided into observation group and control group, 60 patients in each group. Patients in observation group were treated with RFTVR, and patients in control group were treated with new-type fiber-optic CO2 laser. The patients in the two groups were treated with cisplatin injection. The differences of perioperative indexes, swallowing function, pronunciation function, survival period, QOL score and VAS score between the two groups were compared. Results: There was no significant difference in the amount of intraoperative bleeding, operation time and hospitalization time between the two groups (P > 0.05);the correct swallowing of the observation group was significantly higher than that of the control group. After treatment, jitter, shimmer and HNR of the two groups were significantly improved, and jitter and shimmer of the observation group were significantly lower than that of the control group, and HNR was significantly higher than that of the control group (P < 0.05) The QOL score and VAS score of the two groups were significantly improved, and the QOL score of the observation group was significantly higher than that of the control group and the VAS score was significantly lower than that of the control group (P < 0.05);the total survival period and tumor free survival period of the observation group were significantly higher than that of the control group. Conclusion: Compared with CO2 laser treatment, the swallowing function and voice function of patients treated by low temperature plasma radiofrequency ablation were significantly improved, and the life quality of patients was significantly improved by prolonging the survival period of patients..

Prognostic Factors and Survival of Laryngeal Cancer in Cameroon

Background: Laryngeal cancer is a major cause of morbidity and mortality worldwide. It is ranked worldwide as the second ENT cancer with 238,000 new cases and 106,000 deaths each year. In Africa, data on the prognostic factors and the survival of this pathology remain quite limited. Objective: To study the prognostic factors of laryngeal cancer and the survival of patients with laryngeal cancer in Yaoundé and Douala. Methods and Materials: We performed an analytical, longitudinal (retrospective) study over a period from January 1, 2009 to December 31, 2018 including all patients with histologically proven laryngeal cancer, at the ENT, oncological, anatomopathological, radiotherapy and surgery Department of three reference health structures in the cities of Douala and Yaoundé (Laquintinie Hospital and General Hospital of Douala, General Hospital of Yaounde). The data collected were recorded and analyzed by SPSS version 25 and Excel 2013 statistical computer software. Survival was determined by the Kaplan Meier method and the search for prognostic factors was carried out using the Cox proportional hazards model. The significance level was p = 0.05. Results: We selected 80 patients whose vital status we knew and who had been followed up after histological evidence. The sex ratio was 5.66. The median age at cancer diagnosis was 62 years old. 60 (75%) were exposed to tobacco, 52 (65%) had alcohol-tobacco poisoning. The Center and Littoral regions were the most represented with 37.5% and 48.8% respectively. Dysphonia was present in 98.8% of patients. The histological type encountered was squamous cell carcinoma in 78 patients;in the majority of cases the cancer was diagnosed at stage IV and the glottis was the most frequent site (86.2%). The median overall survival was 1.41 with 95% CI [1.08 - 1.74]. The overall survival rates at 1 year, 3 years, 5 years and 8 years were 70%, 18%, 3% and 1.5%, respectively. The poor prognosis factor found was: age greater than or equal to 70 years. Conclusion: Present study showed that survival in laryngeal cancer in Cameroon is very low with a median overall survival of 1.41 years. The overall survival rates at 1 year, 3 years, 5 years and 8 years are 70%, 18%, 3% and 1.5%, respectively. The age greater than or equal to 70 years is the poor prognosis factor, while receiving surgery in combination with neoadjuvant chemotherapy or surgery in combination with adjuvant radiotherapy is the factor of good prognosis.

Association of gastroesophageal reflux disease and laryngeal cancer

Objective:Studies examining the association of reflux disease with the risk of developing laryngeal cancer have both proven and disproven the null hypothesis.Methods:This retrospective caseecontrol study examines the association of reflux in two populations exposed to similar risk factors,including tobacco,to the extent that end-organ malignant transformation has occurred.After IRB approval was obtained,a search of our hospital’s cancer center’s database was performed from 2000 to 2013.A retrospective chart review was then performed and the prevalence of gastroesophageal reflux disease among patients with laryngeal cancer(n Z 290)was determined.It was then compared to the prevalence of gastroesophageal reflux disease among patients presenting with lung cancer(n Z 2440)during the same time period.A multivariate logistic regression was performed to determine the association of reflux with laryngeal cancer.Results:Taking into consideration tobacco use,there was a strong association between male gender and occurrence of laryngeal cancer as opposed to lung cancer(OR Z 3.30;95%CI 2.53e4.36,P<0.001).There was a modest association between reflux and laryngeal cancer(OR Z 1.65;95%CI 1.19e2.25,P Z 0.003).However,there was no association between reflux and the propensity for carcinoma in specific laryngeal subsites(P Z 0.47).Conclusions:In this study examining a heterogeneous population with end-organ malignancy there was a modest association between reflux and laryngeal cancer.Further research is necessary to determine the biologic relevance of this finding.

Larynx Cancer: Review of 11 Years of Activity in the ENT and Head and Neck Surgery Department of University Hospital Gabriel Toure, Bamako

Objectives: To study the epidemio-clinical, therapeutic and evolutionary aspects of laryngeal cancers in the ENT department of the University Hospital Gabriel Toure. Materials and Methods: This was a descriptive, retrospective study over a period of 11 years from January 2008 to December 2019. We made an exhaustive sampling of all cases of malignant tumors of the larynx in the ENT department of the University Hospital Gabriel TOURE. Variables studied: frequency, sex, age, clinic, imaging, histology, TNM classification, treatment received and follow-up time was 1 to 11 years. Result: we noted a male predominance (44 men/13 women). The average age was 52.23 years, with extremes of 32 and 74 years. Smoking was reported by 40 patients (72% of cases). The average in pack-years is 29.32 with extremes of 4 to 60 packs/ year. Alcoholism was reported by 6 patients (9% of cases). Squamous cell carcinoma was the predominant histological type (100%);extension to 2 or 3 floors was objectified in 69% of cases. Complementary radiotherapy in 26 patients after total laryngectomy. Chemotherapy was done in a neoadjuvant situation in 36 cases. Overall survival was: 52.6% at 1 year, 33.3% at 3 years;26.3% at 5 years and 12.28% at 11 years. Conclusion: Most often, late diagnosis is due to the absence of a national strategy and the underestimation of the first symptoms. Surgery coupled with radiotherapy is the treatment of choice.

Tracheoesophageal Voice Prosthesis Outcomes:Success or Insucess?

Introduction: Total laryngectomy/pharingo-laryngectomy is a potentially aggressive surgery for advanced laryngeal/hypopharyngeal carcinomas, which results in important physical and functional changes that compromise some of the most vital functions, including speech communication. For these patients, tracheoesophageal speech is considered to be the gold standard for voice rehabilitation. Objectives: The purpose of the present study was to determinate the success rate of voice prosthesis rehabilitation, voice prosthesis lifetime and the rate of complications, and its related clinicopathologic factors. Material and Methods: Retrospective review of 92 patients who undergone tracheoesophageal puncture (TEP) performed between January 2007 and December 2012 at the Francisco Gentil Portuguese Institute of Oncology of Oporto. Age, primary disease, staging, the extent of surgical resection, radiotherapy treatment, timing of TEP, surgical and prosthesis-related complications were noted. The impact of these clinicpathological factors on functional outcome, complications of TEP and lifetime of prosthetic valves was assessed in univariate analysis. Vocal rehabilitation efficacy with voice prosthesis was assessed with the multidimensional Harrison-Robillard Shultz (HRS) Rating Scale. Lifetime of voice prosthesis and early and late complications were recorded. Results: A total of 83 patients met the study criteria, predominantly males (94%) with a mean age of 63.7 years. 77% of the patients underwent primary and 23% secondary TEP. 68.7% of patients achieved functional tracheoesophageal speech (HRS score ≥ 10), 67.2% had performed primary TEP and 73.7% had performed secondary TEP. The mean device lifetime was 9.8 months for voice prosthesis. Prosthesis-related complications occurred in 81% of the patients and the most common issues were prosthesis leakage (76%) and displacement (22%). The most common surgical-related problem was a large and deep tracheostoma. Conclusions: Our success rate of voice rehabilitation was comparable to that reported in published literature with a satisfactory median device lifetime. Because of its safety and simplicity, tracheoesophageal puncture is considered to be an effective method for voice rehabilitation after total laryngectomy.

A Qualitative Study on Experiences of Patients with Esophageal Speech Training after Total Laryngectomy

Background: Patients who had total laryngectomy not only have a pressure from the possible diagnosis of laryngeal cancer, but also suffer from unspeakable misery. To relieve the suffering, some patients choose esophageal speech training. However, most of the current researches focus solely on the results of the training with the negligence of the patients’ mental health and their life experience during the training. A qualitative research is highly sensitive to patients’ subjective feelings, and thus able to capture their subtle emotional changes. Objective: To explore deeply patients’ real experiences of esophageal speech training after total laryngectomy and reveal the public their training experience of the unique and special group. Methods: In May 2018, researchers conducted a two-month field observation on and in-depth interviews with 15 patients who were on esophageal speech training after total laryngectomy in the esophageal speech training room of the Eye and ENT Hospital of Fudan University. The research applied phenomenological research method and Colaizzi Data Analysis. Results: The data analysis indicated four main themes: changes of mindset;showing positive attitudes and behaviors in training;shift in social relations;and arduous training process. Conclusion: The study has the finding that patients on esophageal speech training had negative emotions in the early stage of the training and dissatisfaction with its teaching. The repercussion of the surgery brought them changes of social relations, social bias and prejudice ensued. It is, therefore, urgent and crucial to give the speech trainees psychological counseling in the early stage to improve their qualities of life, to mobilize social support to incentivize their training, to optimize esophageal speech training teaching, and to regulate the management of the esophageal speech training environment.
