ABSTRACT
Objetivos: Evaluar la efectividad, la seguridad y los costos perioperatorios del abordaje endonasal endoscópico en pacientes con tumores nasosinusales malignos con invasión cerebral. Pacientes y método: Se realizó un estudio observacional de serie de casos. Se compararon 30 pacientes con tumores nasosinusales malignos e invasión cerebral operados (2015-2017) mediante abordaje endoscópico con una serie histórica de 53 casos operados (2010-2015) mediante cirugía abierta. Se utilizó el método de emparejamiento por puntaje de propensión para controlar el efecto de factores pronósticos. Las variables de respuesta primaria fueron el control local y la supervivencia global a los tres años. Se analizaron variables de costo perioperatorio. Resultados: Después del emparejamiento se identificaron 50 pacientes (25 en cada grupo terapéutico) con edad promedio de 55 años, 62% de sexo masculino. Predominó el carcinoma de células escamosas y la invasión cerebral grado II. El control local de la enfermedad a los tres años, la supervivencia global y libre de progresión fueron superiores en el abordaje endoscópico. El abordaje endoscópico redujo el tiempo quirúrgico en 1 hora y 20 minutos y la estadía hospitalaria en 19 días en comparación con la cirugía abierta. El abordaje endoscópico mejoró la independencia funcional y redujo las complicaciones. El ahorro promedio estimado con el abordaje endoscópico fue de aproximadamente $7.355,18 por paciente. Conclusiones: El abordaje endonasal endoscópico constituye un procedimiento seguro, efectivo y más económico en los pacientes con neoplasias nasosinusales malignas e invasión cerebral (AU)
Objectives: To determine the safety, effectiveness and perioperative costs of endonasal endoscopic approach in brain invasive malignant sinonsal tumors patients. Materials and methods: This was a case series bidirectional study; that included 30 brain invasive malignant sinonsal tumors patients treated by endonasal endoscopic approach (2015-2017) and 53 by open surgery (2010-2015). Propensity score matching was used to compensate the prognostic factors; in a sample of 50 patients (25 per group). Primary response variables was local control and 3-years overall survival. Perioperative cost variables were analyzed. Results: A number of 50 patients were included after matching (25 in each therapeutic group). The age average was 55 years and male proportion was 62%. Squamous cell carcinoma and grade II lesions were the most represented in the sample. Endonasal endoscopic approach reduced surgical time in 1 hour 20 minutes, transfusion needs in 5.5 fold and hospitalization in 19 days; in comparison with open technique. Oncologic control based on surgical free margins, local control, overall survival and progression free survival after three years was higher when the resection was performed endoscopically. Functional status was enhanced and complications diminished by using endoscopic approach. Saving was estimated in $7 355.18 per patient. Conclusions: Endonasal endoscopic approach represents a safe, effective and economic procedure in selected patients with malignant sinonasal tumors and brain invasion (AU)

A case-control study was conducted to evaluate the efficacy of an on-going oral cancer screening programme in Cuba in preventing advanced oral cancer in Cuba. The cases for the study consisted of 200 oral cancer patients with stage III and IV disease. Three apparently healthy subjects per case, matched for sex, age (plus or minus 5 years) and residing within a perimeter of 200 m of the house with the case, and willing to be interviewed, were recruited as the controls. Information on socio-economic indicators, smoking, drinking, diet and screening history in the form of visits to the dentist were collected by personal interview with the subjects. Odds ratio (OR), with 95% confidence intervals (CI), of being diagnosed with an advanced oral cancer, in relation to the screening experience at the date of diagnosis of case, 1, 2, 3, 6, and 12 months prior to the date of diagnosis of case were estimated by conditional logistic regression for matched data. The odds ratio of advanced oral cancer associated with screening in relation to screening experience 3 months prior to the diagnosis of the case was 0.67 (95% CI: 0.46-0.95). The odds ratio was 0.91 (95% CI: 0.60-1.37) for a single screening test and 0.41 (95% CI: 0.24-0.68) for two or more tests. The protection offered by screening persisted up to 3 years since the last test. The results of a descriptive evaluation of the programme also revealed limited evidence towards a shift from advanced to early stages after the introduction of the programme. Nonetheless, the results should be interpreted with caution in view of the several limitations in the study, particularly the fact that screening history was established indirectly by interviews and advanced oral cancers constituted the cases, rather than those who died from the disease.

The Cuban oral cancer screening program, functioning since 1984, requires all subjects of > or = 15 years to have an annual oral visual inspection by dentists. It covered 12-26% of the target population annually. Less than 30% of the subjects with suspect lesions complied with referral. The program identified 16% of the 4,412 incident oral cancers in Cuba during 1984-1990. The proportion of stage I cases increased from 24% in 1983 to 49% in 1990, although staging information was available only for half of the cases. There was no change in oral cancer incidence and mortality in Cuba over the last decade that could be ascribed to the screening program.
