Experience with telepathology at a tertiary cancer centre and a rural cancer hospital.

BACKGROUND: Telepathology allows quick and timely access to an expert opinion, no matter where the patient is located. We analysed the experience with the use of telepathology between a tertiary cancer centre and a rural cancer hospital. METHODS: Ninety-three cases were analysed in which static telepathology was used to obtain a consultation between Tata Memorial Centre and Nargis Dutt Memorial Cancer Hospital at Barshi, a rural area. RESULTS: Successful teleconsultation was achieved in all cases. A diagnosis was offered in 92 cases (98.9%) and was deferred in 1 case (1.1%). Complete concordance, clinically unimportant minor discrepancy and hedged diagnosis were obtained in 83 cases (90.2%). Major discrepancies were encountered in 9 cases (9.7%). The number of images per case ranged from 3 to 27 (average: 7 images). Images were of diagnosable quality in 89.2% of cases. Most of the cases (77.4%) were reported within 3 days; 32.2% were reported within 8 hours (a single working day) and 45.1% within 1-3 days. CONCLUSION: Telemedicine can be effectively used to bridge the gap between medically underprivileged, geographically distant rural areas and advanced centres using the static store and forward methodology.

Early detection of cervical cancer with visual inspection methods: a summary of completed and on-going studies in India

La India es un país de alto riesgo de cáncer cervical, donde se presentan cerca de la cuarta parte de los casos del total mundial (126 000 casos incidentes y 71 000 muertes durante 2000). La tasa de incidencia estandarizada por edad se encuentra en el rango de 16 a 55 por 100 000 mujeres en diferentes regiones con tasas particularmente altas en áreas rurales. El control del cáncer cervical por detección temprana y tratamiento es una prioridad del Programa Nacional de Control de Cáncer y, desafortunadamente, no hay programas organizados de tamizaje citológico en este país. La infraestructura técnica y financiera para organizar tamizaje en este tipo de cáncer, ha promovido la inspección visual como una potencial alternativa de la citología cervical en la India. Se investigan cuatro tipos de opciones de detección visual de neoplasia cervical: a) inspección a ojo desnudo sin la aplicación de ácido acético, opción ampliamente conocida como downstaging; b) inspección de ojo desnudo después de la aplicación de ácido acético de 3 a 5 por ciento (VIA); c) VIA usando un dispositivo de aumento (VIAM); d) inspección visual después de la aplicación de yodo-lugol (VILI). Se ha mostrado que el Downstaging ha sido pobremente sensible y específico para detectar neoplasia cervical y no es considerado ampliamente como una prueba de tamizaje conveniente para cáncer cervical. VIA, VIAM y VILI son frecuentemente investigados en estudios de corte transversal multicéntricos (sin verificación de sesgo), en los que se evalúan simultáneamente la citología y las pruebas del VPH; los resultados de esas investigaciones estarán disponibles próximamente. Estos estudios proveerán información valiosa sobre el desarrollo de pruebas comparativas para detectar lesiones de alto grado precursoras de neoplasia cervical, y cáncer invasor. Los resultados de los análisis de los datos de dos estudios previos indicaron una sensibilidad aproximada de 93.4 por ciento y una especificidad de 85.1 por ciento para VIA en la detección de CIN 2-3 o lesiones invasoras, comparadas con las de citología con 72.1 por ciento y 91.6 por ciento de sensibilidad y especificidad, respectivamente. La eficacia de VIA para la reducción de la incidencia y la mortalidad de cáncer cervical y su costo-efectividad están siendo actualmente investigadas en dos ensayos de intervención aleatorizados controlados en población de la India. Uno de esos estudios es un ensayo con cuatro brazos que establece la eficacia...

Early diagnosis of cervical cancers. Our experience at the Rural Cancer Registry, Barshi, India.

In the cervical cancer cases registered at the Cancer Hospital at Barshi, India during 1988-90, 99 of the 105 cases were clinically staged (Total number of cases registered: 136). The annual number of cases were too few for a comparison of stage distribution between the registry years. However, comparison of the proportions of early cases (FIGO Ib, IIa & IIb) in each year, with the corresponding proportion in a large series at the Tata Memorial Hospital (TMH) in Bombay in 1988, showed that the proportions of early cases in 1988 & 1989 (0.31 and 0.35 respectively) were similar to that (0.30) in TMH but in 1990, it (0.50) was significantly higher (P < 0.01). The shift to early stages observed three years after the inception of the Registry is most likely due to the registry activity which involved inter-personal contact with the community and motivation of the symptomatics to undergo a medical investigation. These activities were designed to overcome the adverse conditions for cancer registration prevailing in the rural population. It is suggested that to achieve early diagnosis similar activities be incorporated in the initial phase of a cervical cancer control programme in the country, where cervical cancer is not only the predominant cancer in women but also the cases generally present themselves in advanced stages.

Experience in screening for cervical cancer in rural areas of Barsi Tehsil (Maharashtra).

The organization of cancer detection camps is gaining popularity in our country and it is therefore necessary to evaluate the effectiveness of this approach in the early diagnosis and treatment of cancer. This to our knowledge has not been done. This report analyses an experience in screening for cervical cancer in rural areas of Barsi Tehsil (Maharashtra). The Barsi Tehsil consists of 134 villages with a population of 34,080 women above the age of 30 years (1982-1987). Of these 2,846 were screened through a series of cancer detection camps between 1982 and 1987. The results of the cytological screening in these women have been presented. An evaluation of the camp approach was carried out by the Population based Cancer Registry set up under the National Cancer Registry Programme (Indian Council of Medical Research) in Barsi, Paranda and Bhum tehsils. It was shown that acceptance of cytological screening was poor, thereby indicating that the mere holding of camps was not in itself sufficient to motivate the people, to subject themselves to the Pap smear. Certain suggestions which would appreciably increase the acceptance of cytological screening have been put forward.
