Risk Factors of Oral Squamous Cell Carcinoma with Special Emphasis on Areca Nut Usage and Its Association with Clinicopathological Parameters and Recurrence.

Introduction: Oral squamous cell carcinoma (OSCC) is the most prevalent type of head and neck cancer and is associated with high mortality, particularly in Southeast Asian countries. Areca nut usage, smoking, and alcohol consumption are the most common risk factors for OSCC. Areca nut chewing is highly prevalent in Pakistan and has been attributed to an increase in OSCC cases.

Significance of Estrogen/Progesterone Receptor Expression in Metaplastic Breast Carcinoma.

Introduction: Metaplastic breast carcinoma (MBC) is a rare subgroup of breast neoplasms associated with adverse outcomes because of its aggressive nature. Typically, MBCs show triple-negative hormone receptor (HR) status. Determining the HR status of breast cancer is an integral part because it is an important prognostic factor and helps in the treatment course of the disease.

Diagnostic accuracy of intraoperative frozen section for margin evaluation of oral cavity squamous cell carcinoma.

Objectives: Intraoperative frozen-section evaluation is a valuable technique for detecting positive margins intraoperatively for oral squamous cell carcinoma. We conducted this study to determine the diagnostic accuracy of frozen section in detecting margin status and the effect of tumor grade and stage on diagnostic accuracy.

Results: A total of 251 biopsy-proven cases of oral squamous cell carcinoma were included in this study.

Clinicopathological Parameters Predicting Malignancy in Phyllodes Tumor of the Breast.

Introduction Phyllodes tumor (PT) is an uncommon fibroepithelial neoplasm of the breast. It is a biphasic tumor with stromal and epithelial components, with a tendency to recur. Because of its wide range of disease manifestations, it has been subclassified into three categories, i.

Early-Onset/Young-Onset Colorectal Carcinoma: A Comparative Analysis of Morphological Features and Biomarker Profile.

Introduction Colorectal carcinoma (CRC) is one of the most common cancers that involve the human body. Young-onset CRC (YO-CRC) or early-onset CRC (EO-CRC) is defined as CRC that develops before the age of 50 years, as opposed to CRC that is diagnosed after the age of 50, referred to as late-onset CRC (LO-CRC). EO-CRC is sparsely studied in our population.

Clinicopathological Parameters Predicting Nodal Metastasis in Head and Neck Squamous Cell Carcinoma.

Introduction Squamous cell carcinoma (SCC) is the most common type of malignancy of the head and neck region arising from the mucosal epithelium of the oral cavity and oropharynx. It is a multifactorial disease with a high rate of mortality. Lymph node metastasis is an important prognostic parameter associated with adverse prognosis.

Clinicopathological Profile of a Cohort of Patients With Malignant Melanoma in the United Kingdom.

Introduction Malignant melanoma (MM) is potentially a fatal type of skin cancer and a major health concern for the Caucasian population. It is a heterogeneous disease with a wide spectrum of manifestations. Therefore, in this study, we evaluated the clinicopathological characteristics of MM.

Clinicopathological Parameters Associated With Peritoneal Involvement in Epithelial Ovarian Tumors.

Introduction Ovarian tumors remain one of the leading malignancies of the female genital tract, with a high mortality rate due to their insidious onset and lack of detection at an earlier stage. These tumors metastasize by direct extension into the neighboring pelvic organs; hence, the detection of peritoneal metastasis is valuable for staging and prognostic purposes. Peritoneal wash cytological analysis is an effective predictor of the involvement of the ovarian surface and peritoneal dissemination even in subclinical involvement of the peritoneum.

Effectiveness of non-invasive respiratory support strategies in patients with COVID-19: A systematic review and meta analysis.

Background: BackgroundThe effectiveness of non-invasive respiratory strategies, namely CPAP and HFNO, in reducing the risk of mortality and tracheal intubation in patients with severe COVID-19 is not well established.

Methods: A thorough literature search was conducted across 3 electronic databases (Medline, EMBASE and Cochrane Central) from inception through July 2022. Randomized controlled trials (RCTs) and observational studies assessing the impact of CPAP or HFNO on clinical outcomes in patients infected with COVID-19 were considered for inclusion.

Aggressive Angiomyxoma, Angiomyofibroblastoma, and Cellular Angiofibroma of the Lower Female Genital Tract: Related Entities With Different Outcomes.

Introduction Mesenchymal tumors of the lower female genital tract (FGT) are a miscellaneous group of tumors that include aggressive angiomyxoma (AAM), angiomyofibroblastoma (AMFB), cellular angiofibroma (CAF), and related entities. Histologically, these tumors are composed of stromal cells admixed with vessels, with some minor histological differences. An accurate diagnosis of these tumors is important owing to the differences in the outcome.

Impact of Histological Type and Grade on the Diagnostic Accuracy of Intraoperative Frozen Section for Detecting Breast Cancer Metastasis to Axillary Sentinel Lymph Nodes.

Introduction Intraoperative sentinel lymph node (SLN) evaluation is the standard of care in patients with clinically node-negative breast cancer. The most common histological subtype of breast carcinoma is invasive ductal carcinoma (IDC), followed by invasive lobular carcinoma (ILC). Alternatively, histological grades vary from grades G1 to G3.

Cytogenetic Abnormalities in Myelodysplastic Syndromes: An Overview.

Karyotype is one of the main constituents of the International Prognostic Scoring System (IPSS) and revised-IPSS that are the cornerstones for the prognostication of patients with myelodysplastic syndromes (MDS). Del(5q), -7/del(7q), +8 and -Y are among the most extensively studied cytogenetic abnormalities in MDS. The same applies for normal karyotype.
