Squamous cell carcinoma (SCC) of lower gastrointestinal tract is a rare tumor and duodenum is the most common site of involvement. In addition, involvement of jejunum by SCC is further exceptionally rare, and only nominal cases are present world literature. Being a very infrequent finding, a clinician and a pathologist must be aware of this rare entity. Diagnosis requires histopathology along with clinico-radiological correlation since merely histopathology is unable to differentiate between primary and metastatic tumor...

Epithelial-myoepithelial carcinoma (EMC), a low-grade malignant neoplasm of glandular origin, most commonly involves major and occasionally minor salivary glands. It is rare in minor salivary glands such as hard and soft palate, buccal mucosa, tongue, and so on, frequently affecting geriatric females. EMC comprises diverse histo-pathologic features of an epithelial, myoepithelial de-lineating biphasic pattern along with clear cells, sometimes oncocytic differentiation. Aberrant histo-pathologic features in EMC need judicious discrimination from alike entities, which facilitates appropriate surgical management...

BACKGROUND: The status of the 5-year survival rate and loco-regional recurrence in oral squamous cell carcinoma (OSCC) has remained unchanged over the decades. Recent advances in oral cancer research have revealed that the presence of molecular alterations in histologically tumor-free margins of OSCC has a prognostic significance and can aid in designing therapeutic strategies. However, the literature on molecular studies on histologically tumor-free margins is scant, especially in the Indian population...

BACKGROUND: Though as per literature cancer is also consider an associated risk factor for morbidity and mortality for covid infection but practically most of the cancer patients showed no symptoms with less mortality in second wave of pandemic. So this cross sectional comparative analysis study was designed to see the prevalence of sero-conversion for SARS -coV for IgG in covid infected cancer patients and to compare the IgG antibodies level between covid infected cancer patients and covid infected healthy persons...

BACKGROUND: Tumor-associated macrophages (TAM) are the main component of inflammation along with leukocytes, endothelial cells and fibroblasts together form a tumor microenvironment, with immune cells representing its vital component. Many studies suggested that TAMs cumulating in tumors correlate with a poor prognosis. In prostate cancer, TAMs can increase cancer cell invasion by stimulating tumor angiogenesis, degrading the extracellular matrix, and also suppresses the antitumor functions of cytotoxic T cells resulting in poor prognosis...

INTRODUCTION: Esophageal carcinoma is the fourth most common cancer among males and sixth most common cancer among females in Sri Lanka. Gastric cancer is less common, but its incidence is gradually rising. We conducted a retrospective analysis of survival of esophageal and gastric cancer patients treated at National Cancer Institute, Maharagama, Sri Lanka. METHODOLOGY: Patients with esophageal and gastric cancer treated in three selected oncology units of the National Cancer Institute, Maharagama during 2015 and 2016 were included in the study...

BACKGROUND: The poor response of metastatic osteo- and chondrosarcomas to chemotherapy could be the result of multidrug resistance (MDR), which may be overcome through the use of small interfering RNA (siRNA). However, several methodologic questions remain unresolved. AIMS: To test the toxicity of three commonly used siRNA transfection reagents and apply the least toxic reagent to investigate the siRNA-induced MDR1 mRNA knockdown. METHODS: The toxicity of TransIT-TKO, Lipofectamine 2000, and X-tremeGENE siRNA transfection reagents was investigated on osteosarcoma (MG-63) and chondrosarcoma (SW1353) cell lines...

BACKGROUND: Osteosarcoma is one of the most common childhood bone malignancies. Although chemotherapy protocol including methotrexate is an effective treatment for osteosarcoma, some other regimens have excluded it because of its complications. METHODS: This retrospective study was conducted on 93 children younger than 15 years old who were diagnosed with osteosarcomafrom March 2007 to January 2020. Two chemotherapy protocols were administrated for patients, namely, DCM protocol (Doxorubicin-Cisplatin-Methotrexate) and German protocol (excluding methotrexate)...

BACKGROUND: "Liquid biopsy," where body fluids are screened for biomarkers, is gathering substantial research. We aimed to examine women with suspected ovarian cancer for the presence of circulating tumor cells (CTCs) and study its role in prediction of chemoresistance and survival. METHODS: Magnetic powder labeled monoclonal antibodies for epithelial cell adhesion molecule (EpCAM), mucin 1 cell surface associated, mucin 16 cell surface associated, or carbohydrate antigen 125 (CA125), were prepared according to the manufacturer's protocol...

BACKGROUND: Stem cells exist in niches in the cervical tissue at squamocolumnar junction, which when infected with HR-Human Papilloma Virus undergo malignant transformation to cancer stem cells and have a role in carcinogenesis and metastasis. The expression of CD44, P16, and Ki67 in high-grade squamous intraepithelial lesion (HSIL) and squamous cell carcinoma (SCC) is assessed in this study. MATERIALS AND METHODS: Twenty-six cases each of normal cervix, HSIL, and SCC of cervix cases were subjected to immunohistochemistry markers; p16, Ki-67, and CD44...

BACKGROUND: Nymphaea nouchali Brum is exotic and medicinal plant in India. AIM OF THE STUDY: The main of this study is to evaluate the anticancer properties of Nymphaea nouchali Brum flowers against Ehrlich ascites carcinoma (EAC)-induced Swiss albino mice. MATERIALS AND METHODS: The anticancer properties of Nymphaea nouchali Brum dry and fresh methanol extracts was investigated using EAC in Swiss albino mice. After inoculation of EAC cells into mice, treatment with NNDM flower extract (200 and 400 mg/kg) and standard drug 5-Fluorouracil (20 mg/kg) was continued for 9 days...

BACKGROUND: Cancers of the upper aerodigestive tract constitute approximately 4% of all malignancies. Posttreatment cancer patient faces serious adversities that affect the quality of life. Out of the various scales available to measure the quality of life, we chose the quality of life-oral cancer (QOL-OC), which was developed and evaluated by Nie et al. in 2018. AIMS AND OBJECTIVES: The aim of our study was to assess the quality of life in posttreatment upper aerodigestive tract cancer patients in a tertiary care center and also to check the reliability and validity of the questionnaire QOL-OC...

BACKGROUND: Inflammation has traditionally been considered to be one of the hallmarks of cancer, and systemic inflammatory responses have a prognostic value in many solid cancers. The use of inflammation-based prognostic markers along with traditional clinicopathological prognostic markers in oral cavity cancers has not been studied well. MATERIALS AND METHODS: This is a retrospective study from a prospectively maintained database of patients with oral cancers who were managed in a regional cancer center in south India...

Oral squamous cell carcinoma (OSCC) is the most common cause of morbidity and mortality in India. Buccal mucosa is the most common site because of tobacco quid. Several parameters for the assessment of OSCC have been studied like lymph node metastasis, tumor stage, grade, and perineural invasion. Tumor-associated tissue eosinophilia is another parameter, on which several studies have been done because of its favorable and unfavorable prognosis. The aim of our study is to study quantitative and qualitative eosinophilia in premalignant and malignant lesions of squamous origin in oral cavity with respect to tumor-associated blood eosinophilia...

PURPOSE: Tumour-Node-Metastasis (TNM) staging has been widely used for treatment planning and prognostication of oral cancers; however, TNM staging system alone is insufficient for optimal prognostication. A combined assessment of clinical staging and cytomorphology might serve as a more specific measure for prognostication. The present study attempted to compare the efficacy of histologic grading systems (Jakobbson et al., Anneroth et al. and Bryne et al.) of malignancy in determining the nature and prognosis of oral squamous cell carcinoma (OSCC)...

AIM: Lung cancer has opened a new era in cancer treatment by elucidating the tumor's molecular structure and identifying the targetable mutations. Identifying the targeted mutations in lung cancer constitutes one of the main steps of treatment planning. The frequency of EGFR (epidermal growth factor receptor gene) and ALK (anaplastic lymphoma kinase gene) mutations in non-small cell lung cancer (NSCLC) also varies in populations depending on ethnicity, gender, smoking, and histopathological subtype...

BACKGROUND: Colorectal carcinoma (CRC) is third most common malignancy in the world. The presence of Lymphocytes particularly at the invasive margin of the tumor have been associated with good immune response indicating better prognosis. The relative tumor stroma is also important in deciding the course of the disease. The Glasgow Microenvironment Score (GMS) comprises of assessment of tumor cell infiltrate using Klintrup-Makinen (KM) grade and tumor stroma percentage. AIMS: The aim of the present study is to evaluate the utility of GMS score in relation to parameters of adverse histopathological outcome in carcinoma colon that is grading, staging, LVI, PNI and nodal metastasis...

BACKGROUND: There is little evidence on the efficacy of external beam radiation (EBR) compared to liver resection (LR) for patients with solitary small (≤5 cm) hepatocellular carcinoma (HCC). OBJECTIVE: We aimed to investigate this clinical question based on the Surveillance, Epidemiology, and End Results (SEER) database. METHOD: SEER database was used to identify 416 patients with solitary small HCC who underwent LR or EBR. Survival analysis and Cox proportional hazards model were performed to evaluate overall survival (OS) and identify prognostic factors for OS...
