Heavy smokers with central type squamous cell carcinoma (SCC) frequently have multiple cancerous lesions in the bronchus. Autofluorescence bronchoscopy (AFB) is useful in the detection of early bronchogenic cancer and dysplastic lesions. We investigated the loss of heterozygosity (LOH) and microsatellite instability (MSI) and expression of four proteins in 13 early stage SCC (early SCC) and 9 s...

Background:Squamous cell carcinoma (SCC) is the most common malignancy of the oral cavity, which is highly invasive. Verrucous carcinoma (VC) is the low-grade form of SCC. Epithelial dysplasia (ED) also has a malignant potential. This immunohistochemical (IHC) study aimed to assess angiogenesis and the presence of tumor-associated macrophages (TAMs) in SCC, VC and ED to determi...

1alpha,25-Dihydroxyvitamin D3 (1,25D3) exhibits antitumor activity in a variety of cancers including squamous cell carcinoma (SCC). Intrinsic resistance of SCC cells to cisplatin was observed and led to the investigation into whether 1,25D3 sensitizes SCC cells to cisplatin. Pretreatment with 1,25D3 followed by cisplatin enhanced growth inhibition in SCC cells compared with 1,25D3 alone as asse...

AIM In this study, factors affecting survival, local failure, distant brain failure, whole brain failure and whole-brain radiation therapy (WBRT) free survival according to histological subtypes were investigated in patients with brain metastases from non-small cell lung cancer (NSCLC). MATERIAL AND METHODS Patients with positive pathology reports for adenocarcinoma (ACA) and squamous cell ca...

BACKGROUND AND OBJECTIVES There is little research on training medical students in smoking cessation counseling (SCC). This study aimed to determine if a personal digital assistant (PDA)-based SCC tool can improve medical student SCC. METHODS We conducted a randomized, controlled trial with third-year medical students. SCC behaviors, comfort, and knowledge were assessed using a validated surv...

Small cell carcinoma (SCC) is derived from neuroendocrine cells primarily found in the lung. Extra-pulmonary SCC is relatively rare, comprising <5% of all SCCs. Most extra-pulmonary SCCs are found in the gastrointestinal tract; however, SCC of the rectum is extremely rare. The tumour biology of rectal SCC is similar to that of pulmonary SCC, an aggressive tumour that results in frequent distant...

Speculative Concurrency Control (SCC) [Best92a] is a new concurrency control approach especially suited for real-time database applications. It relies on the use of redundancy to ensure that serializable schedules are discovered and adopted as early as possible, thus increasing the likelihood of the timely commitment of transactions with strict timing constraints. In [Best92b], SCC-nS, a generi...

Cutaneous invasive pigmented squamous cell carcinoma (SCC) is rare. There have previously been only a few case reports or small case series in the English literature [1-13]. In the largest published study there were five cases of pigmented invasive SCC in 46,791 archived cases of invasive SCC (approximately 0.01%) [2]. This compares to pigmented SCC in-situ (pigmented Bowen’s disease) in which ...
