tuberculosis cancer

Cancer (including pancreatic cancer) can develop following a Mycobacterium tuberculosis infection within one year of tuberculosis infection. However, it is unclear whether tuberculosis infection increases the risk of developing adenosquamous carcinoma of the pancreas (ASCP), an extremely rare cancer with a poorer prognosis than pancreatic ductal adenocarcinoma (PDAC). Herein, we report a case of rapid growing ASCP discovered upon a resection for neck tuberculous lymphadenitis. The patient was a 57-year-old woman...

INTRODUCTION AND IMPORTANCE: Tuberculosis (TB) has been one of the most devastating diseases to humanity in recent decades; although pulmonary infection is the most common, infection of any other organ is familiar as well. Colon cancer is another disease affecting the gastrointestinal (GI) system and mostly targets people over 50. Only a few studies mentioned the co-existence of cancer and TB occurring at the same place and time. Hence, the authors report a rare case of concurrent ascending colon adenocarcinoma and colonic TB...

Although silicosis has been an established disease with a recognized cause for more than 100 years, many workers continue to be exposed to silica and new outbreaks of disease continue to occur. This article describes some of the well-established and new exposures, including denim sandblasting, artificial stone cutting, and some forms of "coal worker's pneumoconiosis." The authors review the imaging and pathology of acute silicosis (silicoproteinosis), simple silicosis, and progressive massive fibrosis and summarize known and putative associations of silica exposure, including tuberculosis, lung cancer, connective tissue disease (especially systemic sclerosis), and vasculitis...

Tuberculosis is one of the most common opportunistic infections and a prominent cause of death in patients with human immunodeficiency virus (HIV) infection, in spite of near-universal access to antiretroviral therapy (ART) and tuberculosis preventive therapy. For patients with active tuberculosis but not yet receiving ART, starting ART after anti-tuberculosis treatment can complicate clinical management due to drug toxicities, drug-drug interactions and immune reconstitution inflammatory syndrome (IRIS) events...

Low-dose computed tomography screening for lung cancer is currently targeted at heavy smokers or those with a family history of lung cancer. This study aimed to identify risk factors for lung cancer in individuals who do not meet the current lung cancer screening criteria as stipulated by the Taiwan Health Promotion Agency's low-dose computed tomography (LDCT) screening policy. A cohort analysis was conducted on 12,542 asymptomatic healthy subjects aged 20-80 years old who voluntarily underwent LDCT scans from January 2016 to December 2021...

Conventionally, immunity in humans has been classified as innate and adaptive, with the concept that only the latter type has an immunological memory/recall response against specific antigens or pathogens. Recently, a new concept of trained immunity (a.k.a. innate memory response) has emerged. According to this concept, innate immune cells can exhibit enhanced responsiveness to subsequent challenges, after initial stimulation with antigen/pathogen. Thus, trained immunity enables the innate immune cells to respond robustly and non-specifically through exposure or re-exposure to antigens/infections or vaccines, providing enhanced resistance to unrelated pathogens or reduced infection severity...

OBJECTIVE: The objective of this study was to explore the added value of spectral computed tomography (CT) parameters to conventional CT features for differentiating tuberculosis-associated fibrosing mediastinitis (TB-associated FM) from endobronchial lung cancer (EBLC). METHODS: Chest spectral CT enhancement images from 109 patients with atelectasis were analyzed retrospectively. These patients were divided into two distinct categories: the TB-associated FM group (n = 77) and the EBLC group (n = 32), based on bronchoscopy and/or pathological findings...

Mycobacterium bovis bacille Calmette-Guérin (BCG) is the most effective intravesical immunotherapy for non-muscle invasive bladder cancer (NMIBC), administered after its transurethral resection. Although its instillation is generally well tolerated, BCG-related infectious complications may occur in up to 5% of patients. Clinical manifestations may arise in conjunction with initial BCG instillation or develop months or years after the last BCG instillation. The range of presentations and potential severity pose an imminent challenge for clinicians...

BACKGROUND: Ethiopia, with about 10% of Africa's population, has little direct information on causes of death, particularly in rural areas where 80% of Ethiopians live. In 2019-2020, we conducted electronic verbal autopsies (e-VA) to examine causes of death and quantify cause-specific mortality rates in rural Ethiopia. METHODS: We examined deaths under 70 years in the three years prior to the survey dates (November 25, 2019-February 29, 2020) among 2% of East Gojjam Zone (Amhara Region) using registered deaths and adding random sampling in this cross-sectional study...

BACKGROUND: Lung cancer is one of the most dangerous diseases among cancers and tuberculosis is one of the deadliest infectious diseases in the world. Many studies have mentioned the connection between lung cancer and tuberculosis, and also the microRNAs that play a significant role in the development of these two diseases. This study aims to use different databases to find effective miRNAs and their role on different genes on lung and tuberculosis diseases. Also determining the role of miR-34a and miR-182 in lung cancer and tuberculosis...

Mycobacterium Tuberculosis (Mtb) causing Tuberculosis (TB) is a widespread disease infecting millions of people worldwide. Additionally, emergence of drug resistant tuberculosis is a major challenge and concern in high TB burden countries. Most of the drug resistance in mycobacteria is attributed to developing acquired resistance due to spontaneous mutations or intrinsic resistance mechanisms. In this review, we emphasize on the role of bacterial cell cycle synchronization as one of the intrinsic mechanisms used by the bacteria to cope with stress response and perhaps involved in evolution of its drug resistance...

BACKGROUND: Tumour budding Tuberculosis is a new prognostic marker whose role in breast cancer is still under evaluation. Our aim was to study Tuberculosis in breast carcinoma and correlate it with other prognostic markers. METHODS: A descriptive cross-sectional study was conducted over 2 years on 75 invasive breast carcinoma specimens and biopsies. Hematoxylin and Eosin sections were examined for tumour grade, stage, molecular subtype, necrosis, lymphovascular invasion inflammation and counting of Tuberculosis...

BACKGROUND: Tuberculosis (TB), a highly contagious respiratory disease, presents a significant global health threat, with a notable increase in incidence reported by the WHO in 2022. Particularly, the interplay between TB and non-small cell lung cancer (NSCLC) gains attention, especially considering the rising use of immune checkpoint inhibitors (ICIs) in cancer treatment. This interplay may influence TB diagnostics and reactivation, warranting a closer examination. METHODS: A retrospective analysis was conducted on clinical data of NSCLC patients with positive T-SPOT results before undergoing anti-tumor treatment at Zhongshan Hospital (Xiamen), Fudan University, from January 1, 2021 to December 31, 2022...

Acute respiratory failure (ARF) is a leading cause, along with sepsis, of admission to the intensive care unit (ICU) of patients with active cancer. Presenting variable clinical severity, ARF in onco-hematological patients has differing etiologies, primarily represented by possibly opportunistic acute infectious pneumonia (de novo hypoxemic ARF), and decompensation in chronic cardiac or respiratory diseases (e.g., acute pulmonary edema or exacerbated chronic obstructive pulmonary disease). In these patients, orotracheal intubation is associated with a doubled risk of in-hospital mortality...

Aspartate transcarbamoylase (ATC) is the first committed step in de novo pyrimidine biosynthesis in eukaryotes and plants. A potent transition state analog of human ATCase (PALA) has previously been assessed in clinical trials for the treatment of cancer, but was ultimately unsuccessful. Additionally, inhibition of this pathway has been proposed to be a target to suppress cell proliferation in E. coli, the malarial parasite and tuberculosis. In this manuscript we screened a 70-member library of ATC inhibitors developed against the malarial and tubercular ATCases for inhibitors of the human ATC...

Bacillus Calmette-Guérin (BCG) therapy is an adjuvant treatment for urothelial carcinomas of the upper urinary tract (UTUC). BCG therapy can result in various side effects. We present a case of a 67-year-old female with a history of UTUC who developed disseminated tuberculosis following BCG instillation into the upper urinary tract after conservative management. This complex clinical scenario required a multidisciplinary approach, including antibiotic therapy, immunoglobulin infusion, and tailored tuberculosis treatment...

The incidence and mortality of lung cancer in China are the highest of all malignant tumors, seriously endangering people's lives and health. Refractory lung cancer is lung cancer that is unresponsive to standard treatment and is difficult to treat, or lung cancer for which a standard treatment has not yet been defined. However, there is still a lack of clear definition and consensus on the treatment of refractory lung cancer. In order to provide guidance for the clinically effective and safe treatment of refractory lung cancer, experts from Chinese Thoracic Society Lung Cancer Study Group have formulated this consensus, on the basis of the actual situation in the field of diagnosis and treatment in our country, with reference to the latest research data, relevant guidelines at home and abroad and experts' clinical practice experience...
