This study was conducted to determine whether Bcl-2 overexpression in localized squamous cell carcinoma of the head and neck (SCCHN) might serve as a marker for tumors unlikely to respond to standard treatment. Tissue samples from 33 patients undergoing surgery or irradiation for early-stage SCCHN during the years 1977 to 1992 were stained for Bcl-2. All patients had either T1N0 lesions of the oral cavity, pharynx, or larynx or T1 NO or T2N0 lesions of the true vocal cords. Of the 33 patients, 26 remained disease-free after at least 3 years of follow-up; the remaining 7 patients developed either tumor recurrence or a second primary tumor, 4 of which were fatal. Twelve patients had tissue specimens staining positive for Bcl-2; 6 of these patients had a poor outcome, and 6 had a good outcome. The relationship between poor outcome and overexpression of Bcl-2 in tumor cells was statistically significant (p =.0047 by Fisher's exact test). For tumors overexpressing Bcl-2, there was no significant difference in recurrence rate between those undergoing surgery and those undergoing radiotherapy as the primary mode of treatment. The overexpression of Bcl-2 in early lesions in this study predicted a cure rate of 50%, as opposed to the generally expected 90%, suggesting that Bcl-2 is a significant prognostic indicator in early SCCHN. Future studies will determine if altering the treatment will improve outcome in these patients.

Summary Patients with head and neck squamous cell carcinoma (HNSCC) have an increased risk of developing esophageal second primary tumors (ESPTs). We aimed to determine the incidence, stage, and outcome of synchronous ESPTs in patients with HNSCC in a Western population. We performed a prospective, observational, and cohort study. Patients diagnosed with HNSCC in the oropharynx, hypopharynx, any other sub-location in combination with alcohol abuse, or patients with two synchronous HNSCCs, between February 2019 and February 2020 underwent screening esophagogastroduodenoscopy (EGD). ESPT was defined as presence of esophageal squamous cell carcinoma (ESCC) or high grade dysplasia (HGD). Eighty-five patients were included. A lesion suspected for ESPT was detected in 14 of 85 patients, which was pathologically confirmed in five patients (1 ESCC and 4 HGD). The radiotherapy field was extended to the esophagus in two of five patients, HGD was treated with endoscopic resection in three of five patients. None of the ESPTs were detected on MRI and/or CT-scan prior to EGD. Of the remaining nine patients, three had low grade dysplasia on histology whereas the other six patients had benign lesions. Incidence of synchronous ESPT was 5.9% in our cohort of HNSCC patients. All ESPTs were diagnosed at an early stage and treated with curative intent. We recommend that screening for synchronous ESPTs should be considered in a selected group of patients with HNSCC.

5570 Background: Although Squamous Cell Carcinoma of the Head and Neck (SCCHN) is a non-AIDS defining malignancy, its risk is greater in HIV-positive populations for unclear reasons. Very limited data exist on the clinical presentation, treatment toxicities and outcomes of HIV infected pts with SCCHN, a population frequently excluded from participation in clinical trials. Methods: We present a large case series of HIV infected pts with SCCHN who were recently treated at a single institution. Retrospective chart reviews were performed by treating physicians. Results are reported with descriptive statistics. Results: Thirty individuals with SCCHN reporting HIV infection have been treated by the collaborating physicians from 1997–2005; all were smokers. The average age at diagnosis of SCCHN was 49.3 years (range 33–62), and interestingly, a relatively large number were female (13 of 30, 43%). The median CD4 count of pts was 374/μL, and most pts reported a history of antiretroviral therapy. The most frequent sites of primary disease were the larynx (13 pts, 43%, mostly supraglottic) and oropharynx (13 pts, 43%). Although most patients (87%) presented with advanced (stage III and IV) disease, a few (4 pts, 13%) had stage II disease. Although 12 pts underwent surgical resections for primary treatment, 16 pts underwent primary nonsurgical therapy, including 8 pts treated with chemoradiotherapy. Therapy related toxicities were expected and did not appear different from those observed in immunocompetent individuals. Eight pts had recurrence (7 locoregional/1 distant), and 5 pts died from recurrent/metastatic disease. Three pts had second primary cancers. Conclusions: HIV-infected individuals with SCCHN are generally young smokers, both male and female, receiving active treatment against HIV. The detection of a proportion of pts with early stage disease further supports the role for aggressive smoking cessation counseling and screening efforts for SCCHN in HIV infected populations. Additionally, HIV infection is not a contraindication to aggressive organ-preserving regimens for SCCHN pts with otherwise good functional status. A case-control clinical and pathologic study of SCCHN in HIV infection is planned. No significant financial relationships to disclose.

Metastatic cutaneous squamous cell carcinoma (SCC) of the head and neck poses a significant therapeutic challengedue to its aggressive biologic behavior. We conducted a retrospective study of71 patients—58 men and 13 women, aged 28 to 88 years (mean: 71)—who had been treated atour university-affiliated tertiary care medical center for metastatic cutaneous SCCover a 15-year period. In addition to demographic data, we compiled and analyzed information on tumor characteristics, the site and extent of metastasis, treatment, follow-up, and outcome. Among the tumor factors, poorly differentiated carcinoma was an independent predictor of poorer disease-free survival, and olderage was found to be an independent predictor of poorer overall survival. We found no significant difference in disease-free or disease-specific survival among patients with parotid involvement, neck involvement, or both. In our series, the site of nodal involvement appeared to have no prognostic significance in patients with metastatic cutaneous SCC of the head and neck.

Dnmt1 Expression

AbstractHead and neck squamous cell carcinoma (HNSCC) is the sixth most common type of malignancy in the world. DNA cytosine-5-methyltransferase 1 (DNMT1) play key roles in carcinogenesis and regulation of the immune micro-environment, but the gene expression and the role of DNMT1 in HNSCC is unknown. In this study, we utilized online tools and databases for pan-cancer and HNSCC analysis of DNMT1 expression and its association with clinical cancer characteristics. We also identified genes that positively and negatively correlated with DNMT1 expression and identified eight hub genes based on protein–protein interaction (PPI) network analysis. Enrichment analyses were performed to explore the biological functions related with of DNMT1. The Tumor Immune Estimation Resource (TIMER) database was performed to explore the relationship between DNMT1 expression and immune-cell infiltration. We demonstrated that DNMT1 gene expression was upregulated in HNSCC and associated with poor prognosis. Based on analysis of the eight hub genes, we determined that DNMT1 may be involved in cell cycle, proliferation and metabolic related pathways. We also found that significant difference of B cells infiltration based on TP 53 mutation. These findings suggest that DNMT1 related epigenetic alterations have close relationship with HNSCC progression, and DNMT1 could be a novel diagnostic biomarker and a promising therapeutic target for HNSCC.
