[PMID: 38909840 DOI: 10.1016/j.jid.2024.05.016] [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: 11/11/2023] [Revised: 05/04/2024] [Accepted: 05/09/2024] [Indexed: 06/25/2024]
Abstract
Precise evaluation of repigmentation in vitiligo patients is crucial for monitoring treatment efficacy and enhancing patient satisfaction. This study aimed to develop a computer-aided system for assessing repigmentation rates in vitiligo patients, providing valuable insights for clinical practice. A retrospective study was conducted at the Dermatology Department of Shenzhen People's Hospital between June 2019 and November 2022. Pre- and post-treatment images of vitiligo lesions under Wood's lamp were collected, involving 833 participants stratified by sex, age, and pigmentation patterns. Our results demonstrated that the marginal pigmentation pattern exhibited a higher repigmentation rate of 72% compared with the central non-follicular pattern at 45%. Males had a slightly higher average repigmentation rate of 0.37 in comparison to females at 0.33. Among age groups, individuals aged 0-20 years showed the highest average repigmentation rate at 0.41, while the oldest age group (61-80 years) displayed the lowest rate at 0.25. Analysis of multiple visits identified the marginal pattern as the most prevalent (60%), with a mean repigmentation rate of 40%. This study introduced a computational system for evaluating vitiligo repigmentation rates, enhancing our comprehension of patient responses, and ultimately contributing to enhanced clinical care.

Abstract
INTRODUCTION Head and neck malignancies are responsible for 30% of all cancers in India with a dramatic increase in numbers due to widespread tobacco consumption. This study aims to assess the epidemiological and histopathological spectrum of these tumors. MATERIALS AND METHODS A large retrospective review of 5469 biopsy-proven patients presenting between 2018 and 2022 with head and neck cancers was done. Tumors were analysed for distribution according to sites of presentations, gender, age and histopathological profiles. RESULTS With a male-to-female ratio of 4.2:1, men constituted 80.80% of the study population. Mean age of presentation in women was 53.5 years, whereas men presented at an earlier age of 47.2 years. Oral cavity was the commonest site involved (59.7% cases) followed by the oropharynx (23.8% cases). Buccal mucosa was the commonest subsite involved with 1112 cases followed by tongue lesions with 1088 cases. Larynx was responsible for 17.04% of cases. All subsites were more commonly affected in men with the highest Male: Female ratio of 8.29:1 seen in larynx. The lowest ratio of 1.02:1 was seen in lesions of the face and scalp. Squamous cell carcinoma (SCC) was the most common histopathological diagnosis encountered in 88.97% of cases followed by basal cell carcinoma which was seen in 2.10% lesions. CONCLUSION Oral cavity lesions constitute the bulk of head and neck cancer presentations in India. The disease is more prevalent in men overall and men present at a younger age in comparison to women. SCC is the most prominent histopathology encountered in our study.

Abstract
Introduction: Oral squamous cell carcinoma is a major cause of death throughout the developed world. It is associated with tobacco chewing, paan chewing and alcohol consumption. Human papillomavirus (HPV) type 16 has also been suggested to play a role in the etiology of head-and-neck squamous cell carcinoma (HNSCC). p16 expression is now being used as a surrogate marker of HPV infection in squamous cell carcinoma. Materials and Methods: In this cross-sectional observational study, a total of 100 cases of HNSCC were taken. p16 expression was determined by immunohistochemical (IHC) staining and correlated with clinicopathological parameters. The obtained results were analyzed and evaluated using Chi-square test, value of P < 0.05 was taken significant. Results: P16 was positive in 60% of cases. A statistically significant direct association was observed between p16 with age, site of the tumor, abnormal sexual habits and lymph node involvement. Conclusion: IHC expression of p16 can be used as a surrogate marker of HPV. Study of p16 expression may provide clinicians with more exact information in order to evaluate tumor aggressiveness, treatment modalities and can provide support for vaccination program in a high-risk group.

Abstract
Aims This study aims to report on the demographic profile and treatment pattern of head and neck cancer patients and impact of an early treatment decision on treatment. This study also aims to suggest recommendations to improve treatment compliance. Methods All new patients registered under the head and neck disease management group (DMG) over a period of 3 months at a single center were included. Their demographic details, time to treatment decision, and treatment compliance were determined. The findings were presented to head and neck DMG, and changes were implemented to patient workup with an aim to improve compliance. A reaudit was performed over a period of 3 months and results were compared. Results Two thousand two hundred and forty patients were included in the analysis. Patients with a treatment decision at 1-4 weeks stood at 28.32%, 63.88%, 80.8%, and 89.87%, respectively. Dropout rate was 26%. About 50% of patients planned for surgical intervention could be treated within the institution. After implementation of changes as recommended by DMG, 2418 patients were analyzed and findings were compared to the previous audit. The dropout rate reduced to 17.57%. The number of patients with a treatment decision at 1-4 weeks were 51.26%, 77.42%, 89.46%, and 94.31%, respectively. Conclusion Early treatment decision and referral could significantly improve patient dropout and possibly compliance to treatment. Decentralization of cancer care is urgently needed to manage the high numbers of patients presenting to tertiary care centers. Setting up of new regional cancer centers and increasing infrastructure in the existing centers should be the long-term goals.

Abstract
BACKGROUND Head and neck cancers are among the commonest cancers in the developing world. Personal habits, such as the use of tobacco, betel nut and alcohol are strongly associated with the development of head and neck cancers at certain sites. Therefore, they are among the preventable cancers. In Bhutan, there has not yet been a study conducted on head and neck cancers. OBJECTIVE To describe baseline epidemiological and histopathological characteristics of head and neck cancers in Bhutan. METHODS This is a 7-year descriptive study of all cases of head and neck cancers presented at the Jigme Dorji Wangchuk National Referral Hospital from 2011 to 2017. The data were collected from the hospital's medical records section, histopathology records, patient referral unit and some treatment centres in India. Prior approval was sought from the Research and Ethics Board for Health, the Ministry of Health and the hospital management. RESULTS There were a total of 515 cases of head and neck cancers from 2011 to 2017. The crude incidence rate was 10 per 100,000 and the overall age adjusted rate was 12.3 (95% CI 9.5-15.1) per 100,000 population. The prevalence during this 7-year period was 69.1 per 100,000 population. The commonest cancers are thyroid, oral cavity, hypopharyngeal, laryngeal and nasopharyngeal cancer in decreasing order. Head and neck cancers are more common in males than females in the majority of sites except thyroid, salivary gland and sinonasal malignancies. Thyroid cancers and nasopharyngeal cancers are found to affect younger age groups. Tashigang (48) followed by Paro (43) recorded the highest number of cases. Squamous cell carcinoma is the commonest histopathology type in almost all the cases, while papillary carcinoma is the commonest among thyroid cancers. Personal habits, such as smoking, chewing tobacco, betel nut and alcohol consumption, were found to be more common among patients suffering from oral cavity, laryngeal, hypopharyngeal and oropharyngeal cancers. CONCLUSION Head and neck cancers are the third most common cancer in Bhutan after stomach cancer and cervical cancer. Thyroid, oral cavity and hypopharynx are the top three anatomical sites for head and neck cancers in Bhutan. The current epidemiological and histopathological profile of head and neck cancers will form a baseline of information and basis for further research on head and neck cancers in Bhutan.

Abstract
Aim The purpose of this study was to use a simple, cost-effective technique for studying mitosis in various grades of oral squamous cell carcinoma (OSCC) using 1% Crystal-violet stain and to correlate mitotic frequency index (MFI) obtained by it with Ki67 labeling index (Ki67LI) so as to validate its usefulness as a selective stain for evaluating proliferation. Materials and Methods The invasive front grading score (IFG Score) was recorded in 40 patients of OSCC. Mitotic figures were assessed in hematoxylin and eosin (H and E) stained section as well as in 1% crystal-violet stained section using MFI (MFI = Mitosis/total number of cell counted X100). Comparison between MFI obtained by 1% crystal violet stain and H and E stain was done. Ki67LI was assessed using Ki67 immunohistochemical (IHC) marker. Correlation between Ki67LI and MFI obtained by using 1% crystal-violet stain was performed. Results There was statistically significant increase in MFI obtained by using 1% crystal-violet stain compared to routine H and E stain. Statistically significant positive correlation was observed between Ki67LI and mitosis in well and moderately differentiated OSCC. Positive correlation was also observed in poorly differentiated OSCC, but it was not statistically significant. Both mean MFI and mean Ki67LI significantly increased from grade I to grade II to grade III OSCC. Conclusion 1% crystal violet stain provides a definite advantage over the H and E stained sections. Thus crystal violet stain is easy and cost effective to evaluate proliferation when compared with expensive proliferative IHC marker.

Abstract
INTRODUCTION Demographic, behavioural and environmental factors have been associated with increased risk of head and neck cancer (HNC). We will review published reports and explore connections between risk factors and HNC incidence. This protocol aims to provide strategies for a systematic review and meta-analysis of HNC risk factor analysis in India. It also provides guidelines in order to visualise obtained HNC risk factor data in the form of a heat-map highlighting variations across gender, age and geographical location. METHODS AND ANALYSIS We will identify well-established HNC risk factors and perform a comprehensive systematic review and meta-analysis to quantify each risk factor's impact on HNC incidence. A systematic search will be performed to identify the studies and published reports of HNC risk factors in India. Meta-analysis will be conducted to estimate the proportional contribution of the most prevalent risk factor in HNC on a city-wide basis in Indian states and territories. ETHICS AND DISSEMINATION The review protocol draws on publicly available anonymised data without directly involving human participants and therefore requires neither formal human ethical review nor approval by a human research ethics committee. We published an outline of the protocol in the International Prospective Register of Systematic Reviews (PROSPERO) in 2017. The results will provide an updated analysis of HNC risk factor prevalence in India, and we will discuss the applicability of rehabilitation care. We plan to disseminate the findings of this systematic review through publication in a peer-reviewed journal and presentation at relevant conference proceedings. PROSPERO REGISTRATION NUMBER CRD42017077758.

Abstract
Various studies have demonstrated that the lymphatic system is the additional route for solid tumor metastasis. Lymph nodes metastasis in Head and neck squamous cell carcinoma (HNSCC) is a major prognostic indicator for disease progression and a guide for therapeutic strategies. We conducted a study to compare intratumoral (IT) and peritumoral (PT) lymphatic vessel density (LVD) in HNSCC using lymphatic marker D2-40 and its correlation with lymph node metastasis, histological grading and other clinicopathological parameters. Fifty specimen of HNSCC with modified radical neck dissection tissue were included in the study group. Tissue from tumor, peritumoral tissue, tumor margin and all the lymph nodes were processed for paraffin wax blocks and histopathological diagnosis. Immunohistochemical profile of lymphatic vessels in intratumoral and peritumoral tissue was assessed by subjecting one section each from the tumor and peritumoral tissue to D2-40 immunostain. To determine LVD, four fields with the highest LVD (hot spots) were identified. The mean values were calculated by taking an average of all the measurements. The comparison of LVD between peritumoral and intratumoral area revealed significantly higher PT-LVD (P = 0.001). No significant association was seen between LVD, IT-LVD and PT-LVD and different age groups, gender, site of tumor, risk factors, size of tumor, tumor inflammation, pushing/infiltrating margin and stage of tumors. Significantly higher LVD, IT-LVD and PT-LVD was seen in association with lymph node metastasis. Both high intratumoral and peritumoral LVD were found significantly associated with the presence of lymph node metastasis, however lymphatic vessels were found to be significantly more numerous and larger in peritumoral areas as compared to intratumoral lymphatics. The specificity of D2-40 as a lymphatic endothelial marker was also confirmed. The results of our study support the possibility of using the determination of tumor lymphangiogenesis to identify patients of HNSCC who are at risk of developing the lymph node metastasis.

Abstract
BACKGROUND Laryngeal malignancy is a common malignancy of the head and neck region. Affected patients usually present with features that are characteristic of certain subsites. The larynx is oncologically divided into three: supraglottis, glottis and subglottis. Studies from Western countries have shown that the glottis is the commonest subsite to harbour laryngeal malignancy. However, the supraglottis has been reported to be the commonest subsite in developing countries, including examples in the Indian subcontinent. To our knowledge, no study has been carried out in western Nepal about the epidemiology of laryngeal cancer to date. The purpose of this study was to analyse the epidemiology of laryngeal cancer in relation to its risk factors, age distribution,and preferred subsites and to see if there is any recent change in the subsite wise distribution of laryngeal malignancy in western Nepal. MATERIALS AND METHODS Patients of all ages and both sexes with suspected laryngeal malignancy were enrolled in the initial study. Detailed history taking and clinical examination was performed to find out the involved subsite in relation to the clinical features. Direct laryngoscopy was performed to further confirm the subsite and to take biopsy from the growth under general anesthesia. After confirmation of malignancy from the biopsy report, patients were finally included in the study. Data were analysed and observations were made to find out the distribution of laryngeal malignancy in different subsites. RESULTS The supraglottic larynx was the commonest subsite to harbor laryngeal malignancy. Smoking and alcohol were found to be the common risk factors. The mean age of the patients was in their sixties. CONCLUSIONS Laryngeal malignancy is common in elderly individuals. Supraglottic laryngeal malignancy is the commonest laryngeal malignancy in people who smoke and drink alcohol in Nepal. Avoidance of alcohol use and smoking will be a milestone to reduce the incidence of laryngeal cancers and associated mortality.

Abstract
Objectives. The purpose is to provide detailed estimates of population-based incidences of head and neck cancers (HNCs) between 1999 and 2012 in South Korea and to evaluate trends. Methods. Data was reviewed from the Korea National Cancer Incidence Database regarding the incidence of HNCs between 1999 and 2012. Locations that were surveyed included lip, oral tongue, oral cavity, major salivary gland, nasopharynx, nasal cavity and paranasal sinus, tonsil, hypopharynx, oropharynx, and larynx. Age-standardized incidence rates were calculated and provided with 95% confidence intervals. The increase ratio of HNCs for and male-to-female ratios were also calculated. Results. The incidence of lip (0.07–0.10/100,000 people) and oropharyngeal cancer (0.09–0.12/100,000 people) remained low during the study period while laryngeal cancer (1.17–2.08/100,000 people) occurred most frequently. The incidence of oral tongue, major salivary gland, tonsil, and hypopharynx increased steeply compared to other HNCs between 1999 and 2012. Male-to-female ratio was over 1.0 for all HNCs, especially for those of tonsil, hypopharynx, oropharynx, and larynx cancer which were >5.0. Conclusion. The incidence of all the HNCs except for laryngeal cancer has increased yearly in men and women in South Korea since 1998. Rates of oral tongue, major salivary gland, and tonsil cancer have increased the most rapidly during this time period.

Abstract
BACKGROUND Head and neck cancer without distant metastases is amenable to various modalities of treatment. However, the stage at presentation is a very important determinant for treatment success. The present study was conducted to determine the stage-wise presentation of non-metastatic head and neck cancer patients from the hilly regions in Kumaon division of Uttarakhand, India. MATERIALS AND METHODS The hospital records for non-metastatic head and neck cancer patients from the only functional cancer centre of the region for the period of two-years (January 2012- December 2013) were included. Nasopharyngeal carcinoma was excluded due to its staging system being different. Non-squamous histopathologies were also excluded. Patients hailing from nearby regions of Uttar Pradesh and Nepal were excluded, as were patients from non-hilly regions of Kumaon. RESULTS Of the 271 patients of head and neck cancer, 27 with distant metastases at diagnosis were excluded from the analysis. Of the 244 eligible patient records, 90.1% (n=222) were male, and 9.9% (n=22) were female. The proportions of patients with carcinoma of the larynx, oropharynx, oral cavity, hypopharynx and maxillary antrum were 31.9% (n=78), 27.9% (n=68), 20.5% (n=50), 12.7% (n=31) and 1.2% (n=3). A further 5.7% (n=14) were diagnosed as having secondary involvement of neck nodes with unknown primaries. The proportion of patients presenting in stages I, II, III, IVA and IVB were 0.8% (n=2), 2.5% (n=6), 9.4% (n=23), 51.6% (n=126) and 35.7% (n=87) respectively. CONCLUSIONS An abysmally low proportion (3.3%) of non-metastatic head and neck cancer patients presented in the early stages (I and II). A vast majority of the patients (88.1%) presented with stages IVA and IVB. Not only does this reflect a poor therapeutic outlook, but also exposes the dire need for programmes focusing on cancer awareness and early detection in the region.

Abstract
BACKGROUND A retrospective analysis of all cancer patients attending the radiotherapy outpatient department (OPD) of a single unit during the period of January 2005 till December 2006 was conducted to know the geographical distribution and incidence of the most common cancers, their stage of presentation, treatment compliance among the patients and follow-up. MATERIALS AND METHODS A total of 4,484 patients were registered in the Institute of Medical Sciences, Banaras Hindu University during the period of January 2005- December 2006; of which 1,975 registered in an individual unit were included for the retrospective analysis. RESULTS Most of the patients hailed from the various districts of UP and Bihar. Females outnumbered males with a ratio of 1.33:1. Females mostly belonged to the age group of 40-59 years; whilst males were a decade older. Major cancer sites in females were cervix and breast followed by head and neck. Leading cancer sites in males were head and neck, brain, bone, soft tissue and lung. Most of the cases presented in advanced stage of disease (74%). Squamous cell carcinoma was the most common histopathology (56%). A significant proportion of patients defaulted after undergoing preliminary investigations (16%). Only 53.9% of females and 58.5% of males took treatment out of which 68% and 63% completed the prescribed treatment. Compliance with follow-up was poor. CONCLUSIONS The outcome of this study will significantly help us to define region specific strategies needed for cancer management in eastern Uttar Pradesh.
