RESUMEN
BACKGROUND@#Pre-operative accuracy of subcentimeter ground glass nodules (SGGNs) is a difficult problem in clinical practice, but there are few clinical studies on the benign and malignant prediction model of SGGNs. The aim of this study was to help identify benign and malignant lesions of SGGNs based on the imaging features of high resolution computed tomography (HRCT) and the general clinical data of patients, and to build a risk prediction model.@*METHODS@#This study retrospectively analyzed the clinical data of 483 patients with SGGNs who underwent surgical resection and were confirmed by histology from the First Affiliated Hospital of University of Science and Technology of China from August 2020 to December 2021. The patients were divided into the training set (n=338) and the validation set (n=145) according to 7:3 random assignment. According to the postoperative histology, they were divided into adenocarcinoma group and benign lesion group. The independent risk factors and models were analyzed by univariate analysis and multivariate Logistic regression. The receiver operator characteristic (ROC) curve was constructed to evaluate the model differentiation, and the calibration curve was used to evaluate the model consistency. The clinical application value of the decision curve analysis (DCA) evaluation model was drawn, and the validation set data was substituted for external verification.@*RESULTS@#Multivariate Logistic analysis screened out patients' age, vascular sign, lobular sign, nodule volume and mean-CT value as independent risk factors for SGGNs. Based on the results of multivariate analysis, Nomogram prediction model was constructed, and the area under ROC curve was 0.836 (95%CI: 0.794-0.879). The critical value corresponding to the maximum approximate entry index was 0.483. The sensitivity was 76.6%, and the specificity was 80.1%. The positive predictive value was 86.5%, and the negative predictive value was 68.7%. The benign and malignant risk of SGGNs predicted by the calibration curve was highly consistent with the actual occurrence risk after sampling 1,000 times using Bootstrap method. DCA showed that patients showed a positive net benefit when the predictive probability of the predicted model probability was 0.2 to 0.9.@*CONCLUSIONS@#Based on preoperative medical history and preoperative HRCT examination indicators, the benign and malignant risk prediction model of SGGNs was established to have good predictive efficacy and clinical application value. The visualization of Nomogram can help to screen out high-risk groups of SGGNs, providing support for clinical decision-making.

Objective:To investigate the diagnostic value of endoscopic ultrasound elastography (EUS-E) in endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) for malignant occupying lesions in gastrointestinal adjacent tissue.Methods:Clinical data of 54 patients (57 lesions) undergoing EUS-FNA from January 2020 to April 2021 in the General Hospital of Ningxia Medical University were collected. Thirty patients (31 lesions) who received FNA assisted by EUS-E from May 2020 to February 2021 were enrolled in the EUS-E group, and 24 patients (26 lesions) who underwent routine EUS-FNA without EUS-E in the non-EUS-E group. The diagnostic efficacy of EUS-FNA was evaluated.The diagnostic efficacy of EUS-E group and non EUS-E group was compared. EUS-E score of EUS-E group was analyzed.Results:The overall sensitivity, specificity, positive predictive value, negative predictive value and accuracy of EUS-FNA in the diagnosis of malignant occupying lesions in gastrointestinal adjacent tissue were 80.5% (33/41), 100.0% (16/16), 100.0% (33/33), 66.7% (16/24) and 86.0% (49/57), respectively. There were no significant differences in sensitivity [78.6% (22/28) VS 84.6% (11/13), P=0.232] or accuracy [83.8% (31/37) VS 90.0% (18/20), P=0.156] of EUS-FNA for pancreatic lesions and other lesions (mediastinal and celiac lesions). Postoperative complications occurred in 1 patient (1.85%, 1/54). Also there were no significant differences in sensitivity [84.0% (21/25) VS 81.3% (13/16), P=0.186] or accuracy [87.1% (27/31) VS 88.5% (23/260, P=0.186] of diagnosis of malignant occupying lesions between EUS-E group and non-EUS-E group. In the EUS-E group, EUS-E score≥3 was highly consistent with the definite diagnosis ( Kappa=0.63). Conclusion:EUS-FNA is a safe and effective cytological and pathological method for diagnosis in gastrointestinal adjacent tissue. EUS-E score can well predict benign and malignant lesions, but EUS-FNA assisted by EUS-E does not show superiority in diagnostic sensitivity or accuracy.

Incidence of breast malignancy is increasing in India which can be attributed mostly to changing lifestyle and increased hormone usage, and partly to increasing awareness. We wanted to determine the prevalence of malignant breast lesions in females, evaluate the histological spectrum of malignant breast lesions and study their association with common findings like age, side, histological grade and their biological behaviour.METHODSPresent study is a two-year (August 2016 to July 2018) cross sectional study of malignant lesions of female breast, conducted in the Department of Pathology of Jawaharlal Lal Nehru Medical College, Ajmer, Rajasthan.RESULTSIn this study, 159 malignant lesions of the female breast were diagnosed during study period that comprised of 26.02% of total breast lesions and 1.22 % of the total histopathological samples received. Age of the females having malignant breast lesions ranged from 28 years to 92 years with a mean age of 52.87 ± 12.944 years. The incidence of malignant breast lesions was maximum in 5th and 4th decades of life. The most common clinical symptom for presentation was the palpable lump (79.25%) in the breast. Lesions were more common in the right breast (53.5%), than left. The commonest quadrant involved in malignant lesions of breast was upper outer (30.19%). Infiltrating ductal cell carcinoma was the most common malignant lesion (85.33%) followed by invasive lobular carcinoma (5.66%). Out of 99 specimens having lymph node with it, 65 (65.66%) cases show metastatic deposits of malignancy. Grade II (MBR score) lesions (51.35%) were found most commonly.CONCLUSIONSHistopathology of the malignant lesion is useful in understanding the morphological and biological behaviour of the malignancy as some types of malignancy have aggressive behaviour. Grading and staging have an important role in treatment plan (surgery, radiotherapy, chemotherapy and hormonal therapy) and also in assessing the prognosis
RESUMEN
Background: Tobacco consumption in the form of chewing and smoking is one of the biggest addictions. It causes various oral pre-malignant lesions which mainly include oral sub-mucous fibrosis (OSMF) caused by betel nut consumption and tobacco quid lesion, leukoplakia, erythroplakia and smoker's palate caused by chewing and smoking tobacco. Methods: The data about the past and present consumption of tobacco was collected from 909 individuals. Based on the tobacco habits, the oral cavity findings were assessed and the statistical analysis was carried out to find the significance of associations observed between tobacco consumption and lesions. Results: Out of 909 subjects, 537 were consuming tobacco, out of which 284 were chewers, 65 were smokers and 76 were consuming in both forms. Out of the 284 tobacco chewers, 43% had oral lesions (19.4% had OSMF and 21.5% had tobacco quid) as compared to just 1% of workers having oral lesions (OSMF) amongst those who had no addiction. There was a high prevalence of lesion in tobacco chewers (p<0.005). Out of total smokers, 15.8% had smoker's palate whereas no lesion was seen in the non-addicted workers. The odds of developing oral pre-malignant lesion are 43.62 times higher in exposed individuals. Conclusions: The tobacco consumption in any form is hazardous. Betel nut exposure causes more harmful effect which goes unnoticed. Awareness should be created about various lesions caused by tobacco as well as betel nut and special steps should be taken for early diagnosis and its treatment.
RESUMEN
Prostatic enlargement is a common cause of bladder outlet obstruction among men in India. The enlargement usually leads to lower urinary tract symptoms, irrespective of whether it is benign or malignant. Methods: Forty six patients attending surgical outpatient department of Hi-Tech Medical College, Rourkela with symptoms of bladder outflow obstruction and prostate enlargement were studied. Results: The maximum numbers of patient recruited in the study were in the age range of 56–65 years and 66–75 years, having 14 (30.4%) and 11 (23.9%) cases, respectively. Out of 31 cases which were categorized as malignant on the basis of the serum PSA levels, 27 were confirmed by histopathology & 4 cases which were diagnosed as malignant by serum PSA levels were confirmed as benign by histopathology. Categorization of the Prostatic lesions on the basis of the Sr P.S.A. levels, which were confirmed by CytoHPE the accuracy for BPH was 50% and 67.4 % for malignant lesions. Conclusion: Patients with symptomatic prostate enlargement, serum PSA should be seen as a continuum with increasing risk of prostate malignancy.
RESUMEN
Background: Cervical cancer is the third most commonly diagnosed cancer and the fourth leading cause of cancer death in females worldwide. The disproportionately high burden of cervical cancer in developing countries is largely due to a lack of screening that allows detection of precancerous and early stage cervical cancer. The objective of this study was to identify pre cancer, cancer of cervix by Pap smear test and the factors associated with cervical cancer.Methods: A cross sectional study was done among married women in the reproductive age group of 15-49 years in the urban field practice area of A.J. Institute of Medical Sciences, from Jan 2013 to March 2013. The study comprised of 357 women. A pretested semi structured questionnaire was used to collect data. Screening was done by Pap smear test. Statistical analysis was performed using SPSS software.Results: 49.6% women were in the age group of 40-49 years. 62 (17.4%) were illiterates. 67.5 % belonged to low socioeconomic status. Pap smear test detected premalignant lesions among 2.1% women; no cancer cervix cases were detected. Association between premalignant lesion and educational status, early age at marriage, multi parity, erosion cervix was found to be statistically significant.Conclusions: Regular cytological screening by Pap smear will help in early detection of precancerous lesions and thereby prevent cancer cervix.

The diagnostic effectiveness of Ktrans = 0.21 5 min-1 ,with sensitivity of 81.3% and specificity of 66.7%,was greater than that of Kep =0.477 and iAUC=24.706.Conclusion The DCE-MRI quantitative analysis can provide a reference for the differential diagnosis of HCC from benign liver tumors.
RESUMEN
Photodynamic therapy (PDT) is a simple, minimally invasive treatment modality. It is also known as photoradiation therapy/phototherapy. Photodynamic therapy became more popular when international photodynamic association was formed by Thomas Dougherty in the year 1986. For the first time, it was used in dermatology in the year 1992, later in oncology (1995), microbiology since the year 1996 and itis also been used in dentistry. Three components namely light source, photosensitising agent and oxygen are utilised, which individually are harmless by itself, but when combined with oxygen they produce cytotoxic agents that have the ability to inactivate the tumour cells. This enables the selectivity of the diseased tissue. Main advantages of PDT are as follows: it is cost-effective, can be performed on out-patient basis and tissue heals by little or no scarring. PDT can be used in the treatment of actinic keratosis, Bowen's disease, superficial squamous cell carcinoma, and so on. Uses of PDT are increasing day by day and even nowadays research is going on to make use of nanoparticles in PDT to make it a more promising treatment approach.
RESUMEN
BACKGROUND: Oral squamous cell carcinoma (OSCC) ranks as one of the most common types of cancer and oral potentially malignant lesions (OPMLs) provides with an overall increased risk for development of carcinoma. As podoplanin expression is attracting interest as a marker for cancer diagnosis and prognosis, this study assesses the role of podoplanin expression in such lesions. MATERIALS AND METHODS: Podoplanin expression and lymphatic vessel density (LVD) was determined using D2‑40, a marker for podoplanin, in 70 diagnosed cases of potentially malignant lesions and OSCC. RESULTS: Normal epithelium showed negligible podoplanin expression, whereas the expression extended predominantly at the basal layer and the suprabasal layer or above at one or multiple areas in potentially malignant lesions. Podoplanin expression in OSCC showed two different patterns‑diffuse and focal. A statistically significant increase in mean LVD was seen from normal epithelium to potentially malignant lesions (P < 0.001) and to OSCC (P < 0.022) while a non‑significant increase was seen (P < 0.594) between OPMLs and OSCC. Overall no significant correlation was found between D2‑40 epithelial positivity and LVD (P = 0.122). CONCLUSION: This study suggests the utility of podoplanin as a biomarker for cancer risk assessment as it detects the early changes and thus provides an additional value beyond current clinical and histopathological evaluations. Hence, podoplanin is suggested to be a marker of tumor initiation and to a lesser extent of tumor progression.
RESUMEN
Background : Fine Needle Aspiration Cytology is simple, quick, inexpensive, majority are on OPD basis and minimally invasive technique used to diagnose different types of swellings located in the head and neck commonly originate from cervical lymph node, thyroid, salivary glands and soft tissues. Aim : To assess the frequency of incidences at different sites of head and neck region, and amongst the sex group. To assess distribution amongst inflammatory and neoplastic lesions. Methodology: A retrospective study was conducted at a tertiary care hospital, Ahmedabad from October 2013 to January 2014. Patients between the ages of 1 to 80 years were enrolled into the study. A total of 146 patients with a head and neck swelling underwent FNAC. Fine needle aspiration diagnosis was correlated with detail of relevant clinical findings and investigations. Results : Out of 146 fine needle aspiration procedures, 107 (73.29%) were of lymph nodes, 25 (17.12%) were of thyroid gland, 08 (5.48%) from soft tissue and 06 (4.11%) from salivary glands. Amongst lymph node swellings (73.29%), tuberculous involvement was seen in 73 cases (68.22%) with a female preponderance. Out of total 146 lesions, 109 (74.66%) were inflammatory, 29 (19.86%) were benign and 08 (5.48%) were malignant. Conclusions : The head and neck swellings are very common conditions encountered, with most of them being on OPD basis. Our study found that FNAC is simple, quick, inexpensive and minimally invasive technique to diagnose different types of head and neck swellings. It could differentiate the infective process from neoplastic one and avoids unnecessary surgeries. In case of neoplastic conditions, patient may be referred to Regional Cancer Centre.
RESUMEN
Oral cancer is the most common head and neck cancer, found in 270,000 patients annually worldwide. Some cancers develop from precancerous lesions; however, there is no definitive clinico pathological factor or biomarker that reliably enables malignant transformation to be predicted in an individual patient. Early detection and early treatment of oral cancer are important for improving the survival rate of patients; prevention of oral cancer will clearly contribute most to decreasing its death rate. So correct diagnosis and timely treatment of premalignant lesions with high risk of malignant transformation may help to prevent malignant transformation.

Aim: To assess the prevalence of dental caries, periodontal diseases, oral pre-malignant and malignant lesions in relation to socioeconomic factors among the municipal employees of Mysore city. Settings and Design: The study was cross sectional in nature. Materials and Methods: All the available employees (1187) during the study period were considered. World Health Organization (WHO) Oral Health Assessment form (1997) and a preformed questionnaire were used to collect the required data. Modified Kuppuswamy scale with readjustment of the per capita income to suit the present levels was used for classifying the individuals into different socioeconomic status (SES) categories. Data were collected by a single, trained and calibrated examiner (dentist) using mouth mirror and community periodontal index (CPI) probe under natural daylight. Data analysis was done using SPSS windows version 10. Quantitative data were analyzed using one-way analysis of variance (ANOVA) with Tukey's post hoc test and qualitative data were analyzed using chi-square or contingency coefficient. Results: The age range of the study population was 19-57 years (mean 40.74 years, standard deviation 9.17). The prevalence of dental caries in the upper SES category was lesser (43.3%) compared to that in lower SES category (78.6%). 16.4% of the subjects in the upper category had a CPI score of 0 (healthy periodontium) and none of the subjects in the lower middle, upper lower and lower SES category had this score. The prevalence of oral pre-malignant and malignant lesions was higher in lower SES category (17.9%) than in upper class (0%). Conclusion: There was an inverse relationship between oral health status and SES. The overall treatment need was more in the lower class people than in the upper class.
