Basal-cell carcinoma
In the United States approximately 3 out of 10 caucasians develop a basal-cell carcinoma during their lifetime. This tumor accounts for approximately 70% of non-melanoma skin cancers. In 80 percent of all cases, basal-cell carcinoma affects the skin of head and neck. Furthermore, there appears to be an increase in the incidence of basal-cell cancer of the trunk in recent years.
Basaloid large cell carcinoma of the lung
Bas-LCLC are considered to have a particularly poor prognosis, even compared to other forms of lung cancer. However, not all studies have confirmed this.
Basaloid carcinomas of the lung (like nearly all other recognized subtypes of lung cancer) are highly associated with tobacco smoking. Basaloid architecture in pulmonary carcinomas have been shown to be particularly prevalent in smokers with heavy exposure,
Basaloid forms of lung carcinoma were first described in the peer-reviewed medical literature by Dr. Elisabeth Brambilla and her colleagues in 1992. They were first recognized as distinct clinicopathological variants of both squamous cell and large cell lung cancers in 1999, within the third revision of the World Health Organization lung tumor typing and classification scheme.
