Ki67 Labelling Index predicts clinical outcome and survival in oral squamous cell carcinoma

Objective: To investigate the Ki 67 expression and its correlation with clinicopathological features and 3 years as well as 5 years survival rate in oral squamous cell carcinoma (OSCC). Methodology: Total 217cases of OSCC primarily treated with surgery with or without radiation were included. All patients were followed up for 3 years and 150 were followed up of 5 years for disease free survival. The immunohistochemistry was carried out on neutral buffered formalin fixed paraffin embedded tissue to evaluate the expression of Ki67. Results: The Ki67 labeling index (LI) was significantly higher with respect to adverse clinicopathological parameters such as histopathological grading (p<0.001), clinical TNM staging (p<0.001) and nodal metastasis (p<0.001). The OSCC patients survived for less than 3 and 5 years were showed significantly higher Ki67 LI as compared to diseases free survived more than 3 and 5 years(p<0.001). The three years survival rate of OSCC patient significantly higher with low Ki67 LI (≤45) 96.2%, followed by moderate Ki67 LI (46 to 60) 60.7% and high Ki67 LI (≥61) 37.7% (p<0.001). The five years survival rate of OSCC patient statistically significantly higher with low Ki67 LI (≤45)93.3%, followed by moderate Ki67 LI (46 to 60) 46.8% and Ki67 LI (≥61) 23.3% (p<0.001). Conclusion: The measurement of cell proliferative activity by using Ki67 antigen expression in individual OSCC might provide unique, predictive information on clinical outcome, prognosis and deciding treatment modalities in OSCC

Undifferentiated Nasopharyngeal Carcinoma with Oral Manifestation: A Case Report

Nazofaringealni karcinom (NPC) rijetka je maligna bolest u većem dijelu svijeta, pa se zato često pogrešno dijagnosticira. Ta se vrsta raka teško pronađe među karcinomima glave i vrata zbog predilekcijskog mjesta, malignih karakteristika rasta, posebnih teškoća u otkrivanju i određivanju stupnja proširenosti te visoke stope neuspjeha u liječenju, iako je osjetljiv na radioterapiju. O toj bolesti malo se zna i obično na godinu oboli jedna osoba u populaciji od 100 tisuća. Uobičajen je u južnoj Kini i sjevernoj Africi, gdje se njegova etiologija povezuje s prehrambenim navikama. Kako bismo bolje razumjeli etiološku patogenezu i mogli prepoznati klinička obilježja te postaviti ranu dijagnozu i prognozu NPC-a, izvještavamo o rijetkom slučaju nazofaringealnog karcinoma u srednjoj Indiji. Pacijentica je bila u dobi od 19 godina i došla je na liječenje zbog tkivne mase u sklopu vrata intraoralno uključene u meko nepce.Nasopharyngeal carcinoma (NPC) is a rare malignancy in most parts of the world and is one of the most confusing, commonly misdiagnosed, and poorly understood diseases. It is unusual among all the head and neck cancers due to its marked geographical predilection, highly malignant tumor growth characteristics, special difficulties in detection and staging and a high rate of treatment failure despite of its radiosensitivity. This carcinoma is rare in most parts of the world with reported incidence of around 1 case per 100,000 population per year. Nasopharyngeal carcinoma is common in Southern China and North Africa, where the etiology is related to dietary habits but it is rare in other parts of the world. Therefore, for better understanding of etiopathogenesis, clinical pathological features, early diagnosis and prognosis of NPC, we report a rare case of a nasopharyngeal carcinoma in Central India, of a 19 year old female patient who presented with a mass in her neck and intraoral involvement of the soft palate

Evaluation of chemiluminescence, toluidine blue and histopathology for detection of high risk oral precancerous lesions: A cross-sectional study

<p>Abstract</p> <p>Background</p> <p>Early detection holds the key to an effective control of cancers in general and of oral cancers in particular. However, screening procedures for oral cancer are not straightforward due to procedural requirements as well as feasibility issues, especially in resource-limited countries.</p> <p>Methods</p> <p>We conducted a cross-sectional study to compare the performance of chemiluminescence, toluidine blue and histopathology for detection of high-risk precancerous oral lesions. We evaluated 99 lesions from 55 patients who underwent chemiluminescence and toluidine blue tests along with biopsy and histopathological examination. We studied inter-as well as intra-rater agreement in the histopathological evaluation and then using latent class modeling, we estimated the operating characteristics of these tests in the absence of a reference standard test.</p> <p>Results</p> <p>There was a weak inter-rater agreement (kappa < 0.15) as well as a weak intra-rater reproducibility (Pearson's r = 0.28, intra-class correlation rho = 0.03) in the histopathological evaluation of potentially high-risk precancerous lesions. When compared to histopathology, chemiluminescence and toluidine blue retention had a sensitivity of 1.00 and 0.59, respectively and a specificity of 0.01 and 0.79, respectively. However, latent class analysis indicated a low sensitivity (0.37) and high specificity (0.90) of histopathological evaluation. Toluidine blue had a near perfect high sensitivity and specificity for detection of high-risk lesions.</p> <p>Conclusion</p> <p>In our study, there was variability in the histopathological evaluation of oral precancerous lesions. Our results indicate that toluidine blue retention test may be better suited than chemiluminescence to detect high-risk oral precancerous lesions in a high-prevalence and low-resource setting like India.</p

Clear cell eccrine carcinoma with comedonecrosis in neck region:&amp;nbsp;a &amp;nbsp;rare case report and review of literature

Alka H Hande, Archana M Sonone, Minal S ChaudharyDepartment of Oral and Maxillofacial Pathology, Sharad Pawar Dental College, Sawangi (Meghe), Wardha, IndiaAbstract: Adnexal carcinomas of the skin are rare; they derive from structures such as sweat glands, sebaceous glands, and hair follicles. Adnexal tumors represent 1%&amp;ndash;2% of skin cancers. Carcinomas of the eccrine sweat gland represent a rare group of tumors with potential for local destruction and metastasis. Clear cell changes are a prominent feature in a wide variety of squamous and adnexal carcinomas. Pure clear cell carcinomas of the skin are exceptionally rare. Eccrine clear cell carcinoma is most commonly seen in the scalp region. We represent a rare case report of clear cell eccrine carcinoma with comedonecrosis in the neck region which is an unusual location for this type of tumor.Keywords: adnexal carcinomas, carcinomas of the eccrine sweat gland, clear cell eccrine carcinoma with comedonecrosi

Development of a cost of illness inventory questionnaire for children with autism spectrum disorder in South Asia

BACKGROUND: The economic burden of autism is substantial and includes a range of costs, including healthcare, education, productivity losses, informal care and respite care, among others. In India, approximately, 2 million children aged 2-9 years have autism. Given the likely substantial burden of illness and the need to identify effective and cost-effective interventions, this research aimed to produce a comprehensive cost of illness inventory (COII) suitable for children with autism in South Asia (India) to support future research. METHODS: A structured and iterative design process was followed to create the COII, including literature reviews, interviews with caregivers, pilot testing and translation. Across the development of the COII, thirty-two families were involved in the design and piloting of the tool. The COII was forward translated (from English to Hindi) and back translated. Each stage of the process of development of the COII resulted in the further refinement of the tool. RESULTS: Domains covered in the final COII include education, childcare, relocation, healthcare contacts (outpatient, inpatient, medical emergencies, investigations and medication), religious retreats and rituals, specialist equipment, workshops and training, special diet, support and care, certification, occupational adjustments and government rebates/schemes. Administration and completion of the COII determined it to be feasible to complete in 35 minutes by qualified and trained researchers. The final COII is hosted by REDCap Cloud and is a bilingual instrument (Hindi and English). CONCLUSIONS: The COII was developed using experiences gathered from an iterative process in a metropolitan area within the context of one low- and middle-income country (LMIC) setting, India. Compared to COII tools used for children with autism in high-income country settings, additional domains were required, such as complimentary medication (e.g. religious retreats and homeopathy). The COII will allow future research to quantify the cost of illness of autism in India from a broad perspective and will support relevant economic evaluations. Understanding the process of developing the questionnaire will help researchers working in LMICs needing to adapt the current COII or developing similar questionnaires
