Mitomycin lung toxicity. Acute and chronic phases

American Journal of Clinical Oncology
S H Okuno, S Frytak

Abstract

Pulmonary toxicity is a rare but well described side effect of mitomycin C (MMC). We describe 14 cases of MMC pulmonary toxicity that were detected in four clinical trials performed at The Mayo Clinic using MMC-containing regimens for nonsmall cell lung cancer (NSCLC) and by reviewing the charts of patients treated at The Mayo Clinic with MMC-containing regimens for NSCLC from 1976 to 1995. The median age was 61 (range 44-84) years, with an M:F ratio of 1:1. The median number of cycles of MMC to develop toxicity was four (range two to five) with a median cumulative dose of MMC of 29 mg/m2. MMC toxicity occurred despite pre-medication with corticosteroids in 11 patients. At diagnosis of MMC lung toxicity, the median diffusing lung capacity (DLCO) was 9 and PaO2 was 49 mm Hg. Of those having bronchoscopy, four patients had pulmonary histologic changes consistent with lung injury. Two patients had bronchioalveolar lavages that were nondiagnostic. All patients responded initially to corticosteroids, but approximately 40% had progressive pulmonary insufficiency despite high doses of corticosteroids. This chronic, progressive phase of MMC lung toxicity is a largely underestimated sequelae of MMC.

COVID-19

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

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.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
