Paclitaxel is an active agent for adenocarcinomas and squamous cell carcinomas of the esophagus and is a radiation sensitizer. We sought to investigate the toxicity and complete response rate of paclitaxel, cisplatin, and concurrent radiation for esophageal cancer. Forty-one patients with esophageal cancer were studied, 29 with adenocarcinomas and 12 with squamous cell cancers. Twelve patients had tumor extension into the proximal stomach and/or abdominal adenopathy.

Telomeres are nucleoprotein structures at the ends of chromosomes that are composed of a repetitive G rich sequence and telomeric binding proteins. Telomeres prevent the degradation of chromosomal ends and protect against inappropriate recombination. Telomere attrition involves a tumor suppressor pathway that limits the replication of premalignant cells. The loss of telomeric DNA with each round of replication leads to growth arrest accompanied by senescence or apoptosis. Many tumor cells activate the telomerase gene to bypass senescence.

PURPOSE: To assess the efficacy of rapamycin treatment in chemoprevention and chemotherapy of tumorigenesis in a genetically defined mouse model of head and neck squamous cell carcinoma (HNSCC). Experimental design: Knockdown of Tgfbr1 and/or Pten using siRNA-mediated RNA interference was carried out in human HNSCC cell lines to analyze molecular changes in the mTOR pathway. Tgfbr1(flox/flox); Pten(flox/flox); K14-CreER(tam) mice were treated with oral gavage of tamoxifen for the conditional deletion of Tgfbr1 and Pten in oral mucosa, resulting in HNSCC.

CONTEXT: Human telomerase reverse transcriptase (hTERT), an enzyme that enables cells to overcome replicative senescence and to divide indefinitely, is overexpressed in many cancers and their precursor lesions. OBJECTIVE: To test whether hTERT expression is related to neoplastic progression and resistance to apoptosis in vulvar epithelia. DESIGN: Immunoexpression of hTERT was evaluated in 101 formalin-fixed, paraffin-embedded archival vulvar epithelia consisting of normal squamous vulvar epithelia (n ?=? 25), lichen sclerosus (n ?=?

OBJECTIVES: The objective of this study was to identify novel survival-associated biomarkers in oral rinse samples collected from patients with oral squamous cell carcinoma (OSCC). MATERIALS AND METHODS: We screened for putative survival-associated markers using publicly available methylation array data from 88 OSCC tumors. Cox models were then fit to methylation array data restricted to these putative loci in oral rinse samples of 82 OSCC patients from greater Boston.

Artemisinin (AR) is a widely used antimalarial drug. Recently, additional uses for AR as an anticancer drug were discovered. Using TUNEL, immunohistochemistry (IHS) markers and flow cytometry techniques, we evaluated the effect of AR and 5-FU on HPV 16 immortalized and transformed human gingival epithelial (IHGK) cells. The results of TUNEL showed that AR-treated IHGK cells consisted of 82% positive cells, while 5-FU-treated cells consisted of 18% positive cells.

Chemoprevention of head and neck squamous cell carcinoma (HNSCC), a disease associated with high mortality rates and frequent occurrence of second primary tumor (SPT), is an important clinical goal. The epidermal growth factor receptor (EGFR)-signal transducer and activator of transcription (STAT)-3 signaling pathway is known to play a key role in HNSCC growth, survival, and prognosis, thereby serving as a potential therapeutic target in the treatment of HNSCC.

Curcumin (diferuloylmethane) is a polyphenol derived from the Curcuma longa plant, commonly known as turmeric. Curcumin has been used extensively in Ayurvedic medicine for centuries, as it is nontoxic and has a variety of therapeutic properties including anti-oxidant, analgesic, anti-inflammatory and antiseptic activity. More recently curcumin has been found to possess anti-cancer activities via its effect on a variety of biological pathways involved in mutagenesis, oncogene expression, cell cycle regulation, apoptosis, tumorigenesis and metastasis.
