Adapting biomodulatory strategies for treatment in new contexts: pancreatic and oral cancers (Conference Presentation)

(1) Background: Gingival cancer has a significant incidence and is often diagnosed at advanced stages. The aim of this paper is to highlight its clinical aspects on the basis of a case series analysis in order to promote awareness and improve the diagnosis process. (2) Methods: Oral cancers diagnosed and treated at three Italian University Hospitals over ten years were retrospectively investigated. Cancer location on the gingiva, edentulous ridge, and retromolar pad was addressed. Data regarding clinical features, stage at the diagnosis, and time from presenting symptoms to first medical consultation were retrieved. (3) Results: Thirty-three cancers located on the gingiva, edentulous ridge, and retromolar pad were retrieved from 276 total oral cancer cases (11.9%). A median of 50 days (range 2–300) passed for the patient to seek for a medical evaluation. At the time of diagnosis, 63.3% were advanced stage cancers, mainly located at the mandible (91%), especially in the retromolar pad (48.5%) and the edentulous alveolar ridge (24.2%). Lesions were red (45.5%), red and white (45.4%), or white (9.1%), appearing as an ulcer (69.7%), exophytic mass (12.1%) or flat lesion (12.1%). Sixty-six percent of cancers were completely asymptomatic, regardless their clinical appearance. A statistically significant association between the time from the presentation of symptoms to the first medical consultation and the cancers stage was found. (4) Conclusions: The clinical appearance of gingival cancer is very polymorphous; its understanding may be significant to improve patient education and early medical consultation.

Abstract Objectives The aim of the present study is to evaluate the role of immunoglobulins (IgA, IgG, and IgM) and circulating immune complexes (CIC) as tumor marker in oral cancer and precancer patients. Materials and Methods The present study was performed on 45 individuals subdivided into three groups, that is, oral precancer, oral cancer and healthy individuals, and levels of immunoglobulins, and CIC was estimated by turbidometry and ELISA method. Results In the present study, the mean serum IgA levels in oral precancer were 161.00 ( ± 118.02) mg/dL, oral cancers were 270.67 ( ± 171.44) mg/dL, and controls were 133.73 ( ± 101.31) mg/dL. Mean serum levels of IgG in oral precancer were 1,430.87 ( ± 316) mg/dL, oral cancers were 1,234.27 ( ± 365.42) mg/dL, and controls were 593.87 ( ± 323.06) mg/dL. Conclusion We found that the levels of serum IgG and IgA were elevated consistently in precancer and cancer group, and Serum IgM levels were increased only in precancer. Also, significant increase in serum CIC levels were seen in oral precancer and cancer group on comparison with control.

Risk Of Cancer

AbstractKeloid is a skin disease characterized by exaggerated scar formation, excessive fibroblast proliferation, and excessive collagen deposition. Cancers commonly arise from a fibrotic microenvironment; e.g., hepatoma arises from liver cirrhosis, and oral cancers arise from submucosal fibrosis. As keloids are a prototypic fibroproliferative disease, this study investigated whether patients with keloids have an increased cancer risk. In a matched, population-based study, first 17,401 patients treated for keloids during 1998–2010 with 69,604 controls without keloids at a ratio of 1:4 were evaluated. The association between keloids and risk of cancer was estimated by logistic regression or Cox proportional hazard regression models after adjustment of covariates. In total, 893 first-time cases of cancer were identified in the 17,401 patients with keloids. The overall cancer risk was 1.49-fold higher in the keloids group compared to controls. Regarding specific cancers, the keloids group, had a significantly higher risk of skin cancer compared to controls (Relative risk = 1.73). The relative risk for skin cancer was even higher for males with keloids (Relative risk = 2.16). Further stratified analyses also revealed a significantly higher risk of developing pancreatic cancer in female patients with keloids compared to controls (Relative risk = 2.19) after adjustment for known pancreatic cancer risk factors. This study indicates that patients with keloids have a higher than normal risk for several cancer types, especially skin cancers (both genders) and pancreatic cancer (females). Therefore, patients with keloids should undergo regular skin examinations, and females with keloids should regularly undergo abdominal ultrasonography.
