Management of Extraocular Retinoblastoma: ICMR Consensus Guidelines.

Retinoblastoma (RB) is the most common intraocular malignancy of childhood. Advanced stage presentation of RB is common in low middle-income countries (LMICs) due to lack of awareness, social taboos associated with enucleation, seeking alternative conservative treatment options, and poor accessibility to health care. Over the last few decades, there have been significant advancements in the management of extraocular RB (EORB) which have improved outcomes and helped in minimizing treatment-related toxicities. The incorporation of multimodality approaches including chemotherapy, surgery, and radiotherapy (RT) has shown promising results; however, prognosis remains poor especially in LMICs. In this article, authors have discussed the ICMR consensus guidelines on the management of EORB, including metastatic RB.

Management of Intraocular Retinoblastoma: ICMR Consensus Guidelines.

Retinoblastoma (RB) is the most common childhood intraocular malignancy. Delayed presentation due to a lack of awareness and advanced intraocular tumors are a common scenario in low-middle income countries (LMICs). Remarkable treatment advances have been made in the past few decades allowing globe salvage in advanced intraocular RB (IORB) including systemic chemotherapy with focal consolidation and targeted treatments like intraarterial chemotherapy and intravitreal chemotherapy. However, a lack of availability and affordability limits the use of such advances in LMICs. External beam radiotherapy, despite risk of second cancers in RB with germline mutations, still remains useful for recalcitrant RB not responding to any other treatment. When choosing conservative treatment for advanced IORB, the cost and long duration of treatment, morbidity from multiple evaluation under anesthesias (EUAs), side effects of treatment and risk of treatment failure need to be taken into account and discussed with the parents. In this article, the authors discuss the ICMR consensus guidelines on the management of IORB.

Epidemiology, Diagnosis and Genetics of Retinoblastoma: ICMR Consensus Guidelines.

Retinoblastoma (RB) is the most common intraocular tumor in childhood. It is mainly caused by mutations in both alleles of the RB1 tumor suppressor gene that is found on chromosome 13 and regulates the cell cycle. Approximately 8000 children are diagnosed with RB globally each year, with an estimated 1500 cases occurring in India. The survival rate of RB has improved to more than 90% in the developed world. Leukocoria and proptosis are the most common presenting features of RB in Asian Indian populations. Most cases of RB are diagnosed by fundus examination followed by ultrasound. The International Classification of Retinoblastoma is the most used scheme for the staging and classification of intraocular RB in India. Prenatal testing and preimplantation genetic testing for RB may be beneficial in high-risk families. Histopathologic risk factors such as massive choroidal invasion and post-laminar optic nerve help in predicting the occurrence of metastasis in children with RB, while presence of microscopic residual disease requires aggressive adjuvant treatment in eyes enucleated for group E RB. The review provides a consensus document on diagnosis and genetics of RB in India.

Tata Memorial Centre Evidence Based Management of Colorectal cancer.

ABSTRACT: This review article examines the evidence-based management of colorectal cancers, focusing on topics characterized by ongoing debates and evolving evidence. To contribute to the scientific discourse, we intentionally exclude subjects with established guidelines, concentrating instead on areas where the current understanding is dynamic. Our analysis encompasses a thorough exploration of critical themes, including the evidence surrounding complete mesocolic excision and D3 lymphadenectomy in colon cancers. Additionally, we delve into the evolving landscape of perioperative chemotherapy in both colon and rectal cancers, considering its nuanced role in the context of contemporary treatment strategies. Advancements in surgical techniques are a pivotal aspect of our discussion, with an emphasis on the utilization of minimally invasive approaches such as laparoscopy and robotic surgery in both colon and rectal cancers, including advanced rectal cases. Moving beyond conventional radical procedures, we scrutinize the feasibility and implications of endoscopic resections for small tumors, explore the paradigm of organ preservation in locally advanced rectal cancers, and assess the utility of total neoadjuvant therapy in the current treatment landscape. Our final segment reviews pivotal trials that have significantly influenced the management of colorectal liver and peritoneal metastasis.

Natural History of Germline BRCA1 Mutated and BRCA Wild-type Triple-negative Breast Cancer.

We report a deep next-generation sequencing analysis of 13 sequentially obtained tumor samples, eight sequentially obtained circulating tumor DNA (ctDNA) samples and three germline DNA samples over the life history of 3 patients with triple-negative breast cancer (TNBC), 2 of whom had germline pathogenic BRCA1 mutation, to unravel tumor evolution. Tumor tissue from all timepoints and germline DNA was subjected to whole-exome sequencing (WES), custom amplicon deep sequencing (30,000X) of a WES-derived somatic mutation panel, and SNP arrays for copy-number variation (CNV), while whole transcriptome sequencing (RNA-seq) was performed only on somatic tumor.There was enrichment of homologous recombination deficiency signature in all tumors and widespread CNV, which remained largely stable over time. Somatic tumor mutation numbers varied between patients and within each patient (range: 70-216, one outlier). There was minimal mutational overlap between patients with TP53 being the sole commonly mutated gene, but there was substantial overlap in sequential samples in each patient. Each patient's tumor contained a founding ("stem") clone at diagnosis, which persisted over time, from which all other clones ("subclone") were derived ("branching evolution"), which contained mutations in well-characterized cancer-related genes like PDGFRB, ARID2, TP53 (Patient_02), TP53, BRAF, BRIP1, CSF3R (Patient_04), and TP53, APC, EZH2 (Patient_07). Including stem and subclones, tumors from all patients were polyclonal at diagnosis and during disease progression. ctDNA recapitulated most tissue-derived stem clonal and subclonal mutations while detecting some additional subclonal mutations. RNA-seq revealed a stable basal-like pattern, with most highly expressed variants belonging to stem clone. SIGNIFICANCE: In germline BRCA1 mutated and BRCA wild-type patients, TNBC shows a branching evolutionary pattern of mutations with a single founding clone, are polyclonal throughout their disease course, and have widespread copy-number aberrations. This evolutionary pattern may be associated with treatment resistance or sensitivity and could be therapeutically exploited.

[90Y]Yttria Alumino Silicate Glass Microspheres: A Biosimilar Formulation to "TheraSphere" for Cost-Effective Treatment of Liver Cancer.

Background: Selective internal radiation therapy (SIRT) using a suitable ß--emitting radionuclide is a promising treatment modality for unresectable liver carcinoma. Yttrium-90 (90Y) [T1/2 = 64.2 h, Eß(max) = 2.28 MeV, no detectable γ-photon] is the most preferred radioisotope for SIRT owing to its favorable decay characteristics. Objective: The present study describes indigenous development and evaluation of intrinsically radiolabeled [90Y]yttria alumino silicate ([90Y]YAS) glass microsphere, a formulation biosimilar to "TheraSphere" (commercially available, U.S. FDA-approved formulation), for SIRT of unresectable liver carcinoma in human patients. Methods: YAS glass microspheres of composition 40Y2O3-20Al2O3-40SiO2 (w/w) and diameter ranging between 20 and 36 µm were synthesized with almost 100% conversion efficiency and >99% sphericity. Intrinsically labeled [90Y]YAS glass microspheres were produced by thermal neutron irradiation of cold YAS glass microspheres in a research reactor. Subsequent to in vitro evaluations and in vivo studies in healthy Wistar rats, customized doses of [90Y]YAS glass microspheres were administered in human patients. Results: [90Y]YAS glass microspheres were produced with 137.7 ± 8.6 MBq/mg YAS glass (∼6800 Bq per microsphere) specific activity and 99.94% ± 0.02% radionuclidic purity at the end of irradiation. The formulation exhibited excellent in vitro stability in human serum and showed >97% retention in the liver up to 7 d post-administration when biodistribution studies were carried out in healthy Wistar rats. Yttrium-90 positron emission tomography scans recorded at different time points post-administration of customized dose of [90Y]YAS glass microspheres in human patients showed near-quantitative retention of the formulation in the injected lobe. Conclusions: The study confirmed the suitability of indigenously prepared [90Y]YAS glass microspheres for clinical use in the treatment of unresectable hepatocellular carcinoma.

Evaluation of an Objective MRI-Based Tumor Regression Grade (mrTRG) Score and a Subjective Likert Score for Assessing Treatment Response in Locally Advanced Rectal Cancers-A Retrospective Study.

Purpose: Magnetic resonance imaging (MRI) with the help of MRI-based tumor regression grade (mrTRG) score has been used as a tool to predict pathological tumor regression grade (pTRG) in patients of rectal cancer post-neoadjuvant chemoradiation. Our study aims to evaluate the ability of MRI in assessing treatment response comparing an objective mrTRG score and a subjective Likert score, with a focus on the ability to predict pathologic complete response (pCR). Methods: Post-treatment MRI studies were retrospectively reviewed for 170 consecutive cases of histopathologically proven rectal cancer after receiving neoadjuvant chemoradiation and prior to surgery by two oncoradiologists blinded to the eventual postoperative histopathology findings. An objective (mrTRG) and a subjective Likert score were assigned to all the cases. Receiver operating characteristic curves were constructed to determine the ability of Likert scale and mrTRG to predict pCR, with postoperative histopathology being the gold standard. The optimal cutoff points on the scale of 1 to 5 were obtained for mrTRG and Likert scale with the greatest sum of sensitivity and specificity using the Youden Index. Results: The most accurate cutoff point for the mrTRG to predict complete response was 2.5 (using Youden index), with a sensitivity of 69.2%, specificity of 69.6%, positive predictive value (PPV) of 85.6%, negative predictive value (NPV) of 46.4%, and accuracy of 69.3%. The most accurate cutoff for the Likert scale to predict complete response was 3.5, with a sensitivity of 47.5%, specificity of 89.1%, PPV of 91.9%, NPV of 39.4%, and accuracy of 59%. mrTRG had a lower cutoff and was more accurate in predicting pCR compared to Likert score. Conclusion: An objective mrTRG was more accurate than a subjective Likert scale to predict complete response in our study.

Cross-sectional imaging review of common to uncommon lung cancer mimickers in a tertiary care oncology center.

Lung cancer is the most diagnosed cancer worldwide. Many non-malignant pulmonary lesions, such as tuberculosis, fungal infection, organizing pneumonia, inflammatory myofibroblastic tumor, and IgG4 disease, can mimic lung cancer due to their overlapping morphological appearance on imaging. These benign entities with minor differentiating imaging clues may go unnoticed in a high-volume cancer institution, leading to over-investigation that may result in repeated biopsies, pointless wedge resections, and related morbidities. However, with a thorough medical history, laboratory diagnostic work-up, and careful analysis of imaging findings, one can occasionally restrict the range of possible diagnoses or arrive at a definitive conclusion. When imaging features overlap, image-guided lung sampling is crucial since histopathological analysis is the gold standard.

MRI in rectal cancer patients on 'watch and wait': patterns of response and their evolution.

PURPOSE: Evaluate MR patterns of response and their evolution in rectal cancer patients on watch and wait (WW). METHODS: We retrospectively reviewed 337 MRIs of 60 patients (median follow-up: 12 months; range: 6-49 months). Baseline MRIs (available in 34/60 patients) were evaluated for tumor morphology, location, thickness, circumferential involvement, nodal status and EMVI. First post-treatment MRIs (in all patients) were additionally evaluated for pattern of response on T2 and DWI. Change in post-treatment scar thickness and scar depth angle between the first and second post-treatment scans was also evaluated. Evolution of the response pattern/recurrence were evaluated till the last available scan. RESULTS: On the baseline scans, 20/34 (59%) patients had polypoidal tumor with 12/20 having ≤ 25% circumferential wall involvement. We saw five patterns of response-normalized rectal wall (2/60-3%), minimal fibrosis (23/60-38%), full thickness fibrosis (16/60-27%), irregular fibrosis (11/60-18%) and split scar (6/60-10%), with 2/60 (3%) showing possible residual disease. On the first post-treatment scans, 12/60 (20%) had restricted diffusion, with 3/12 having persistent restriction till last follow-up. Post-treatment fibrosis/split scar remained stable in 44/60 (73%) cases and improved further in the rest. 9/60 (15%) patients developed regrowth/recurrence. Patients with recurrence had < 10 mm scar thickness and < 21° change in scar angle between the first and second post-treatment MRIs. CONCLUSION: Most patients on WW protocol developed minimal or full thickness fibrosis, majority of which remained stable on follow-up.

Imaging of central nervous system emergencies in oncology.

Central nervous system (CNS) may be predisposed to devastating complications in cancer patients which may add to morbidity and mortality in this group. Majority of the complications are vascular in nature due to the altered coagulation profile and pro-inflammatory state in these patients. However, there are a host of other conditions which may affect the clinical course of these patients including metabolic and toxic encephalopathies, infections, and paraneoplastic syndromes. Moreover, multimodality management of these patients, which is often used in majority of the cancers, exposes them to treatment related complications. This pictorial review aims to enlighten the reader regarding the various complications affecting the CNS as seen at our tertiary cancer care institute. We aim to highlight the emergent nature of these complications and the need to identify them quickly and accurately on imaging which helps to institute early appropriate management and prevents further morbidity and mortality.

A dosimetric comparison of systemic peptide receptor radionuclide therapy and intra-arterial peptide receptor radionuclide therapy in patients with liver dominant gastroenteropancreatic neuroendocrine tumours.

OBJECTIVES: Intra-arterial radionuclide therapy (IART) treatment allows direct delivery of 177 Lu-DOTATATE to the overexpressed somatostatin-positive neuroendocrine liver metastases, which led to higher tumour concentration compared with systemic radionuclide therapy (SRT). The aim was to evaluate and compare the absorbed doses of both IART and SRT to organs and hepatic metastatic sites. METHODS: A total of 48 patients received SRT and IART. In SRT, activity was administered intravenously, whereas in IART, activity was administered directly into hepatic arteries. The sequential whole-body images were acquired at 2, 4, 24, 72 and 160 h. The reconstructed whole-body planar and single-photon emission computed tomography-computed tomography images were processed using the Dosimetry Toolkit for the estimation of normalized cumulated activity in the organs and tumour lesions. The absorbed dose was computed using OLINDA EXM 2.0 software. RESULTS: The median absorbed dose (mGy/MBq) of kidneys and spleen in IART was compared with SRT and found to be decreased by 30.7% ( P  = 0.03) and 37.5% ( P  = 0.08), whereas it was found to be increased by 40% ( P  = 0.26) and 8.1% ( P  = 0.28) in the liver and lungs. The median dose (mGy/MBq) of tumours determined in IART was found to be increased by 62.2% ( P  = 0.04). CONCLUSION: IART with 177 Lu-DOTATATE significantly increases tumour dose while reducing overall systemic toxicity in comparison to SRT treatment. After considering the maximum tolerance limit of kidneys in peptide receptor radionuclide therapy, the number of treatment cycles and injected activity can be optimized further with IART for better response and survival.

Multimodality liver directed treatment for colorectal liver metastasis: Array of complementary options can improve outcomes - A single centre experience from India.

AIM: Complimentary use of Liver directed therapies (LDTs) with systemic chemotherapy has improved oncologic outcomes in colorectal liver metastasis (CRLM). We analysed institutional results of multimodality management. Methods: Retrospective analysis of prospectively maintained database of CRLM patients managed with LDT including surgical resection, Ablation, Transarterial chemoembolization (TACE) or Transarterial radioembolization (TARE) between November 2011 to March 2020. Management plan was decided in multidisciplinary meeting. Resectable tumours underwent surgical resection or ablation or both in some cases. Borderline resectable or unresectable disease was treated with down staging chemotherapy or TACE/TARE followed by resection or ablation. All patients received adjuvant chemotherapy. Factors influencing survival were analysed. Results: Out of total 375 patients, surgery alone was done in 191 (50.93%) patients while surgery with other LDT in 26 patients (6.93%). Ablation alone was done in 100 (26.66%) whereas TACE/TARE were done as standalone treatment in 21 (5.6%) and 7 (1.86%) patients respectively. TACE + ablation was done in 28 (7.46%) and TARE + ablation was done in 2(0.53%) patients.5-year Overall Survival(OS) was 49.8% while Event free survival(EFS) was 21.4%. The median OS and EFS for surgical group was significantly better than non-surgical group (78 V/s 39 months; p<0.05 and 20 V/s 15 months p <0.005). The resectable (78 months) group had better median OS as compared to borderline resectable and Unresectable group (39 months and 29 months). Male gender, resectable disease and surgical intervention were associated with improved OS. Conclusion: Although surgery remains the mainstay of treatment, complementary use of non-surgical LDT with systemic therapy offers possibility of good outcomes in advanced liver limited disease. Our experience highlights the impact of multidisciplinary care in optimizing CRLM treatment.

Leiomyosarcoma of inferior vena cava (IVC): do we really need to reconstruct IVC post resection? Single institution experience.

BACKGROUND: Inferior vena cava (IVC) leiomyosarcomas (LMS) are a rare group of retroperitoneal tumors. R0 surgical resection is the only curative modality of treatment. IVC resection for retroperitoneal sarcoma is a complex surgery with no definitive guidelines for reconstruction. METHODS: Retrospective review of all patients who underwent surgical resection of primary leiomyosarcoma of the IVC requiring resection from 2010 to 2020 at our tertiary care center was performed. RESULTS: Among 24 patients who required IVC resection for LMS, only 7 (29%) required reconstruction of IVC. According to Clavien-Dindo classification, there was one grade 3 or more morbidity and 1 post-operative mortality. Seventeen patients underwent R0 resection whereas 7 patients had R1 resection on final histopathology. At a median follow-up of 25 months (range 8-91 months), the median OS was 40 months with median DFS of 28 months. Two patients presented with local recurrence while 13 patients developed systemic recurrence on follow-up. CONCLUSION: Careful preoperative multidisciplinary planning can make IVC resection without reconstruction feasible with acceptable perioperative morbidity, mortality, and oncological outcomes for IVC LMS.

Fat necrosis: A consultant's conundrum.

Fat necrosis of the breast is a benign non-suppurative inflammation of the adipose tissue and often mimics breast cancers, posing a diagnostic challenge for the clinician and radiologist. It has a myriad of appearances on different imaging techniques, ranging from the pathognomic oil cyst and benign dystrophic calcifications to indeterminate focal asymmetries, architectural distortions, and masses. A combination of different modalities can assist a radiologist in reaching a logical conclusion to avoid unnecessary interventions. The aim of this review article was to provide a comprehensive literature on the various imaging appearances of fat necrosis in the breast. Although a purely benign entity, the imaging appearances on mammography, contrast-enhanced mammography, ultrasound, and magnetic resonance imaging can be quite misleading, especially in post-therapy breasts. The purpose is to provide a comprehensive and all-inclusive review on fat necrosis with a proposed algorithm allowing a systematic approach to diagnosis.

A study of the clinical profile, predictors, prognostic features, and survival of patients with hepatocellular carcinoma having macroscopic portal vein tumor thrombosis.

BACKGROUND: Macroscopic portal vein tumor thrombosis (PVTT) is considered a negative prognostic factor in hepatocellular carcinoma (HCC) patients. There is divergent opinion regarding management of these patients worldwide. We aimed to evaluate the clinical profile, predictors, prognostic features, and survival of patients of HCC with PVTT. METHODS: Treatment-naïve HCC patients with and without PVTT were analyzed retrospectively using a prospectively accrued dataset. Patients with PVTT were further divided as per treatment groups for survival analysis. RESULTS: Of 508 patients, 46.1% had radiological evidence of PVTT at presentation. On logistic regression, serum albumin (odds ratio [OR]=0.65, 95% confidence interval [CI]= 0.44-0.96; p= 0.031); international normalized ratio (OR = 3.78,95% CI = 1.42-10.00; p=0.008); alpha-feto protein >400 ng/mL (OR=3.58, 95%CI = 2.00-6.40; p <0.001); size of largest tumor nodule >5 cm (OR =6.37, 95%CI =2.03-19.99; p =0.002); and male gender (OR =1.84, 95%CI = 1.01-3.33; p = 0.045) were independent predictors for PVTT. Patients with PVTT amenable to aggressive therapies had significantly better median overall survival (in months) as compared to those receiving sorafenib or best supportive care only (13.1, 3.9, and 1.8 respectively, p<0.0001). Treatment modality received (p<0.001) and extrahepatic metastasis (p=0.006) were independent predictors of mortality in these patients. CONCLUSION: Size of largest tumor nodule >5 cm and alpha-fetoprotein >400 ng/mL are strongly associated with the presence of PVTT in patients with HCC. A multidisciplinary approach may identify a subgroup of patients who can be offered aggressive therapies like surgery and/or locoregional therapy with significant survival benefit.

Prognostic value of lung shunt fraction in hepatocellular carcinoma and unresectable liver dominant metastatic colorectal cancer undergoing transarterial radioembolisation.

AIM: To assess the overall survival and determine whether pre-TARE shunt fraction, tumor volume and tumor marker impact the outcome. METHODS: This is a retrospective study of 75 patients who were referred for 90Y-glass microsphere radioembolisation by a joint clinic decision between 1 January 2010 and 31 December 2014. All patients underwent pre-TARE CECT and 99mTc-MAA lung shunt fraction (LSF) imaging. RESULTS: Overall survival was 19 months for hepatocellular carcinoma (HCC) and 24 months for metastatic colorectal carcinoma. For hepatocellular carcinoma-LSF higher than 6.51 % was predictive of significantly decreased survival (P value 0.00). A progressive disease in survival was observed as LSF increased from less than 6.51 % to more than 20%. Tumor volume and tumor marker did show correlation with patient outcomes. For metastatic colorectal carcinoma-LSF and tumor marker did not show significant correlation with survival and tumor volume showed significant correlation with survival with P value of 0.049.

Hepatic tuberculosis masquerading as malignancy.

BACKGROUND AND AIMS: Hepatic tuberculosis (HTB) is rare and mimics neoplastic liver lesions clinico-radiologically leading to misdiagnosis and even unnecessary surgery. METHODS AND MATERIAL: We analysed 43 cases of HTB diagnosed at a referral cancer centre over 10 years. Clinical details, investigations and treatment received were noted. RESULTS: The median age was 46 years with a female preponderance (58%). HTB was diagnosed incidentally in 28% cases during surveillance imaging for a previous cancer. Constitutional symptoms (31, 72%), abdominal pain (25, 58%), fever (12, 28%), hepatomegaly (22, 51%), elevated alkaline phosphatase (34, 79%), elevated aminotransferases (18, 42%) and hypoalbuminemia (19, 45%) were common features. All cases had negative HIV serology and normal tumor markers. Twenty-two (52.5%) had solitary liver lesion and lesions > 2 cm in 28 (65%). Ultrasound showed hypoechoic lesions in 31 of 33 cases. Computed tomography showed hypodense lesions (43,100%) with mild peripheral enhancement (32, 74%). Calcifications (5, 12%) and capsular retraction (8, 19%) was uncommon. MRI was performed in seven cases commonly showed T1 hypointense, T2 hyperintense lesions with restricted diffusion. Histopathology showed granulomatous inflammation (42, 97.5%), Langhan's giant cells (41, 95%) and caseation necrosis (35, 85%). Acid-fast stain and PCR positivity was uncommon. Extrahepatic organs were involved in 20 (46.5%). HTB mimicked cholangiocarcinoma (25, 58%), liver metastasis (11, 26%) and lymphoma (3, 7%). Six patients underwent liver resection with a presumptive diagnosis of cancer without a preoperative biopsy. All patients received antitubercular therapy, 37 had clinico-radiological response, there were 3 deaths and 3 patients were lost to follow-up. CONCLUSION: HTB is rare and can mimic a malignancy clinico-radiologically. Calcifications and pseudocapsule appearance on multiphase CT scan may help in differentiating HTB from hepatic malignancy. Tumor markers are normal while histopathology is generally diagnostic. A high index of suspicion is required to avoid unnecessary surgery as the patients respond well to ATT. TRIAL REGISTRATION: This is a retrospective and observational study hence clinical trial registration is not applicable.

Tobacco and cancer awareness program among school children in rural areas of Ratnagiri district of Maharashtra state in India.

Background: Promoting awareness of tobacco and cancer in the community needs multipronged efforts. We performed a study to evaluate whether we could raise awareness about the harmful effects of tobacco, oral and esophageal cancer among school students by providing them health education. Moreover, we also compared the awareness level in students of age group 12 to ≤14 years with the age group >14 to 18 years. Methods: We conducted an awareness program in the schools of Ratnagiri district of Maharashtra state. Students aged 12-18 years participated in this study. We provided health education to school students using a standard presentation; the presentation was rich in illustrations depicting the harmful effects of tobacco as well as oral and esophageal cancer's signs, symptoms, diagnosis, treatment, and preventive measures. After the health talk, a questionnaire was circulated. The questions were focused on tobacco, signs, and symptoms of the diseases along with early detection, prevention, and treatment of cancer. Results: A total of 1354 students participated in the program. Totally, 567 (41.9%) students were from 6th to 8th grade (Group A, age group 12 to ≤14) and 787 (58.1%) students were from 9th to 12th standards (Group B, age group >14 to 18). Overall scores were high, ranging from 69% to 98%. Group A scored in the range of 69% to 95%, and Group B scored in the range 72%-98% The difference between the two groups was found to be statistically significant (P-value ≤0.05). Conclusion: A standardized health education program helped to raise awareness about the harmful effects of tobacco and cancer amongst school children. Further studies are needed to evaluate whether educating school children has an impact on community understanding of the disease.
