Ameloblastoma demographic, clinical and treatment study - analysis of 40 cases

Dental lesions represent about 1% of oral cavity tumors being ameloblastoma the most common one. It is a tumor of epithelial origin that mainly affects the jaw, and less commonly the maxilla. Its clinical presentation is that of an asymptomatic slow-growing tumor. Despite being a benign tumor, it has an invasive behavior with a high rate of recurrence if not treated properly. Objective: To describe the cases of ameloblastoma in a reference department. Methods: Retrospective analysis of 40 cases. The variables analyzed were: age, gender, ethnicity, tumor location, type of treatment, complications and recurrence. Results: The most affected gender was male - 21 cases (52.5%); with a predominance of Caucasians - 24 cases (60%). The mean age was 35.45 years; the most common location was in.the jaw - 37 cases (92.5%). Facial asymmetry was the most frequent complaint. Of the 40 cases, 33 were submitted to surgery. Of those submitted to surgery, 24 (72.72%) underwent segmental resection, with recurrence in 4 (12.12%) cases. Conclusion: Ameloblastoma may relapse when treatment is not performed with broad surgical resection of the lesion with wide safety margins

Avaliação epidemiológica e da resposta terapêutica no câncer da hipofaringe

Despite the low incidence, diagnostic and therapeutic advances, hypopharyngeal cancer still has high mortality.Objective: To evaluate retrospectively the epidemiological profile and response to surgery and radiation/chemotherapy of patients with hypopharyngeal cancer.Method: We reviewed the medical records of 114 patients treated between 2002 and 2009 in a tertiary hospital with histopathological diagnosis of squamous cell carcinoma.Results: the mean age of the patients was 57 years, 94.7% were males and 5.3% females, 98.2% were smokers and 92% consumed alcohol; 72% are illiterate or did not complete first grade schooling. the main complaints were: neck node (28%), pain and dysphagia (22%), odynophagia (12.2%), dysphonia (7.8%). the clinical staging was: I (1.7%), II (3.5%), III (18.4%), IV (76.3%). the treatment was carried out with radiotherapy and chemotherapy alone in 35%, with mean 2-year survival of 20% and 5-year survival of 18%; surgery followed by radiotherapy and chemotherapy in 22.8% with 2-year survival of 60.0% and 5 years of 55.0%; chemotherapy alone in 2.6%, and 39.4% without treatment.Conclusion: Most patients already had advanced clinical stages and independent of the treatment option, had a low survival rate, confirming the poor prognosis of this neoplasm.Fed Univ São Paulo UNIFESP, São Paulo, BrazilHeliopolis Hosp, Dept Head & Neck Surg & Otorhinolaryngol, São Paulo, BrazilLusiada Fdn, Dept Surg, Sch Med Sci, Santos, SP, BrazilSao Jose Hosp RBBP, São Paulo, BrazilUniv São Paulo, Sch Med, Dept Surg, BR-05508 São Paulo, BrazilHeliopolis Hosp, Dept Hlth, São Paulo, BrazilSao Jose Hosp, RBBP, São Paulo, BrazilUniv São Paulo, Sch Med, Dept Head & Neck Surg, Larynx Grp, BR-05508 São Paulo, BrazilUniv São Paulo, Sch Med, Dept Head & Neck Surg, BR-05508 São Paulo, BrazilFed Univ São Paulo UNIFESP, São Paulo, BrazilWeb of Scienc
