Evaluation of P53 and CK20 Immunohistochemical Markers in Comparison with Morphologic Findings in Low- and High-grade Urothelial Carcinomas.

Background & Objective: Urothelial carcinoma is the seventh most common cancer in the world. The histological classification of papillary carcinoma is one of the most important determinants for its prognosis. Sometimes there is an overlap in the extent of the tumor, and the accurate microscopic diagnosis of the tumor is not always easy.

An Investigation on the Results of Cytopathologic Tests of Pancreatobiliary System Performed in the Pathology Department in Iran.

Background & Objective: Pancreatobiliary system disorders commonly include inflammatory diseases and tumors. Diagnosis of pancreatic cancer is challenging and is mostly achieved when the disease has extensively progressed, and metastasis has occurred. Therefore, this study was performed to evaluate cytopathology in the diagnosis of Pancreatobiliary malignancies, which can improve diagnostic adequacy and accuracy.

Diagnostic Utility of Combined CEA, CA15-3 and CA125 Biomarkers and Cytomorphology in Suspicious and Malignant Serosal Fluid.

Background & Objective: Early detection of malignancies in the serous fluids has been remained an issue. A classic diagnostic tool for the ascites and pleural effusions is cytologic study (morphology) with approximately 98% specificity for the detection of cancer cells. This study aimed to evaluate the diagnostic value of three complementary markers in the serosal fluids of patients with malignant cytology and suspected cases.

COVID-19 and Influenza Co-infection: A Systematic Review and Meta-Analysis.

Co-infection of COVID-19 with other respiratory pathogens which may complicate the diagnosis, treatment, and prognosis of COVID-19 emerge new concern. The overlap of COVID-19 and influenza, as two epidemics at the same time can occur in the cold months of the year. The aim of current study was to evaluate the rate of such co-infection as a systematic review and meta-analysis.

Different Strains of BK Polyomavirus: VP1 Sequences in a Group of Iranian Prostate Cancer Patients.

Purpose: BK virus (BKV) has a worldwide seroprevalence in humans. Based on sequences of the major capsid proteins, i.e.

Spiritual Therapy in Coping with Cancer as a Complementary Medical Preventive Practice.

There are many of methods of treating cancer. However, the concept of curing the cancer is beyond our current knowledge. Some patients who have the cancer may seek an alternative manner of curing their disease.

End of Life Issues in Cancer Cases: Ethical Aspects.

This article investigates ethical challenges cancer patients face in the end stages of life including doctors' responsibilities, patients' rights, unexpected desires of patients and their relatives, futile treatments, and communication with patients in end stages of life. These patients are taken care of through palliative rather than curative measures. In many cases, patients in the last days of life ask their physician to terminate their illness via euthanasia which has many ethical considerations.

Polyomavirus Hominis 1(BK virus) Infection in Prostatic Tissues: Cancer versus Hyperplasia.

Purpose: Polyomavirus hominis 1, better known as BK virus (BKV) infection might be a predisposing factor for prostate cancer (PCa). The aim of this study was to compare the frequency of BK virus infection in pathological specimens of patients with PCa compared to patients with benign prostatic hyperplasia.

Materials And Methods: From July 2011 to June 2012, paraffin-embedded tissue blocks of patients with PCa (60 specimens) and also with benign prostatic hyperplasia (60 specimens) were investigated.

Increased trend of breast cancer mortality in Iran.

Background: Breast cancer is the most commonly diagnosed cancer in women worldwide In Iran, it ranks first among cancers diagnosed in women and is the fifth most common cause of death. The aim of this study was to present the mortality trends from breast cancer for Iranian women during a period of almost a decade, in order to provide update information regarding the likely future.

Methods: We analyzed National death Statistic reported by the Iranian Ministry of Health and Medical Education from 1995 to 2004 to generate annual mortality rates/100,000, overall, by age group (<15, 15-49 and ≥ 50 years of age) and age standardized rate (ASR).

Pancreatic cancer mortality and misclassification--bayesian analysis.

Background: Pancreatic cancer is a fatal cancer with a 5-year survival of only about 4% for all tumors. Mortality is a familiar projection to address the burden of cancers, but according to the Iranian death registry, about 20% of death statistics are still recorded in misclassified categories. The aim of this study was to estimate pancreatic cancer mortality for Iranian population, using a bayesian approach in order to revise this misclassification.
