To determine the most effective treatment and long-term outcome of patients with stage IB carcinoma of the cervix. From January 1999 to December 2001, 106 women with cervical cancer stage IB received neoadjuvant chemotherapy (n = 52) or primary surgery (n = 54). These were randomly assigned. Clinical effects and pathological changes were simultaneously recorded. The overall clinical response rate was 84.6% and included a complete response (CR) in four patients (7.7%), partial response (PR) in 40 patients (76.9%), and stable disease (SD) in the remaining eight patients (15.4%). Surgery revealed positive nodes in 9.6% neoadjuvant chemotherapy group patients and in 29.6% primary surgery group patients (P = 0.014). Similar results occurred with vascular space involvement: 27.8% in the primary surgery group compared to 9.6% in the neoadjuvant chemotherapy group (P = 0.024). However, parametrial infiltration was found in 7.4% of the patients in the primary surgery group, while only 3.8% showed it in the neoadjuvant chemotherapy group (P = 0.679). The overall 5-year survival rate was significantly higher for all patients who received neoadjuvant chemotherapy (84.6%) than for the control group (75.9%) (P = 0.0112). The median survival ...Continue Reading

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.


Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.
