RESUMO

Background: Endocrine therapy for breast cancer is directed at reducing oestrogen synthesis or alternatively blocking oestrogen receptors (ER) in tumour-sensitive tumors. Despite side effects, the use of systemic adjuvant therapy after local management of breast cancer substantially improves survival and reduces the risk of relapse. The study objective was to assess the recurrence of breast cancer and the complications seen in breast cancer patients on tamoxifen therapy at a hospital-based cancer registry, Thrissur, Kerala.Methods: After obtaining institutional ethical clearance, included 75 patients of histologically diagnosed breast carcinoma currently on tamoxifen, diagnosed in the year of 2016. Data was obtained from the patient files and by personal intimation.Results: Of the 75 patients on tamoxifen, four (5.33%) patients had history of recurrence. 22.6% of patients on tamoxifen were noted to have increased endometrial thickness. Other side effects noted were weight gain, TIA, bone pain and vaginal discharge.Conclusions: It was found that the recurrence rate at three years for the study population was 5.33%. More studies from developing countries, with larger sample size and clinical trials will give us more accurate information regarding the efficacy of the drug.

RESUMO

Resumen Objetivo: Proporcionar características demográficas y clínicas, así como estimaciones de supervivencia global a tres años de pacientes con cáncer epitelial de ovario (CEO) tratadas entre 2005 y 2014 en el Instituto Nacional de Cancerología de Colombia (INC). Métodos: Se incluyeron 783 pacientes diagnosticadas y tratadas por primera vez en el INC por CEO en los periodos 2005-2008, 2009-2011 y 2012-2014 sin un diagnóstico previo de otro cáncer. Se cruzaron datos del registro hospitalario de cáncer con bases de datos gubernamentales para obtener información de seguimiento. Utilizando el método Kaplan-Meier se estimó la probabilidad de sobrevivir a 36 meses a partir de la fecha de ingreso, evaluando diferencias en supervivencia entre grupos con la prueba de rango logarítmico. Se utilizaron modelos multivariados de riesgos proporcionales de Cox para evaluar: el efecto relativo de edad, el estadio clínico, el subtipo histológico y el tipo de tratamiento inicial en la supervivencia. Resultados: La probabilidad de supervivencia global a 36 meses fue de 56,5% (IC 95%: 53,0; 60,0), que se mantuvo estable en los tres periodos. La edad avanzada, el estadio clínico y el subtipo histológico afectaron significativamente la supervivencia global a tres años: 49,5% (IC 95%: 43; 55,6) para mujeres >59 años; 21,9% (IC 95%: 14,7; 29,2) para la enfermedad en estadio IV y 56,3% (IC 95%: 37,5; 54,3) para los tumores serosos. Las estimaciones de hazard fueron significativamente más altas en pacientes de 59 años o más (HR 1,54 (IC del 95%: 1,04 a 2,27)) y en cánceres con estadio avanzado (HR 13,47 (IC 95%: 7,92-22,92)); la cirugía más quimioterapia tuvo una reducción en el riesgo en comparación con otros tratamientos (HR 0,84 (IC 95% 0,52-1,36). Conclusiones: La supervivencia del cáncer epitelial de ovario se mantuvo estable con el tiempo. La variación se presentó en factores como: la edad, el estadio clínico y el primer tratamiento.


Abstract Aims: To provide demographical and clinical characteristics and estimations of 3-year overall survival of epithelial ovarian cancer (EOC) patients treated at the Colombian National Cancer Institute (INC) between 2005 and 2014. Methods: All 783 patients first treated at INC for EOC in the three periods: (2005-2008, 2009-2011, 2012-2014), without a prior cancer diagnosis, were included in this study. Follow-up was realized by cross-linkage with governmental databases using person identification numbers. Probability of surviving 36 months since the date of entry at INC was estimated using Kaplan-Meier methods, using the log-rank test to evaluate differences between groups. We used multivariate Cox proportional hazard models to evaluate the relative effect of age, clinical stage, histological subtype and treatment first on survival. Results: The overall survival probability at 36 months was 56.5% (95% CI: 53.0, 60.0), which was stable over time. Advanced age and clinical stage significantly affected 3-year overall survival, being 49.5°% (95°% CI: 43.4, 55.6) for age > 59, 21.9°% (95°% CI: 14.7, 29.2) for stage IV disease and 56.3% (95% CI: 37.5, 54.3) for serous tumors. Hazard ratios were significantly higher for patients aged 59 and over (HR 1.54 (95%CI 1.04-2.27)) and advanced stage cancers (HR 13.47 (95%CI 7.92-22.92)), whereas patients with surgery plus chemotherapy had a strongly reduced risks compared to other treatments (HR 0.84 (95%CI 0.52-1.36)). Conclusions: Survival of epithelial ovarian cancer was stable over time, with a variation according to age, clinical stage and first treatment.

RESUMO

Objetivo: Caracterizar los casos de cáncer atendidos en la Unidad de Cáncer del Hospital Departamental de Villavicencio (Colombia). Métodos: Estudio de cohorte retrospectivo basado en datos rutinarios de las características demográficas y clínicas de los casos de cáncer infiltrantes y casos in situ para el periodo 20062008. Se realizó un análisis general y uno específico para cuatro localizaciones principales (cuello del útero, mama, estómago y próstata) y cáncer en niños. Se hicieron comparaciones entre grupos mediante Chi cuadrado y se usaron frecuencias y medidas de tendencia central para las variables categóricas y numéricas. Resultados: Se analizaron 1.617 casos de cáncer, 95,7% fueron infiltrantes. La media de edad fue de 57 años (DE±18 años). El 68,7% residía en Villavicencio. Las primeras localizaciones fueron en orden descendente: piel (19,2%), cuello del útero (14,5%), mama (10,5%), estómago (8%), y próstata (5,3%); los grupos diagnósticos más frecuentes en niños: leucemias, linfomas y otras neoplasias epiteliales malignas. El 8,2% de los pacientes habían muerto al momento de la recolección de información, 20,5% por cáncer de estómago. Conclusiones: Se evidenció mayor proporción de casos en mujeres y una tercera parte sin aseguramiento en salud. Los cánceres más frecuentes en hombres fueron piel y próstata; en mujeres, cáncer de cuello uterino y mama, con mayor proporción en los estadios clínicos localmente avanzados. En ninños el principal diagnóstico fue la leucemia. Esta información institucional constituye una base importante para acercarse a describir el comportamiento del cáncer en el orden local.


Objective: To characterise the cases of cancer treated at the Cancer Unit of the Villavicencio Departmental Hospital (Colombia). Methods: A retrospective cohort study was conducted based on routine data to describe the demographic characteristics of all newly diagnosed cancer cases (both in situ and invasive) collected in the hospital-based registry through active search for the period 2006-2008. In-depth analyses were performed for four major cancer sites (cervix uteri, breast, stomach, prostate), and childhood cancers. Comparisons between groups were made using frequencies and measurements of central tendency to summarise the numerical and categorical variables, as well as Chi-squared tests. Results: Of a total of 1,617 new cancer cases were analysed, 95.7% of which were invasive. The mean age was 57 years (SD 18 years), 68.7% were residents of Villavicencio. The most common locations were, in descending order: skin (19.2%), cervix uteri (14.5%), breast (10.5%), stomach (8%), and prostate (5.3%). The most common diagnostic groups in children were: leukaemia, lymphoma, and other malignant epithelial neoplasms. Of the 8.2% of patients who died at the time of data collection, 20.5% were due to stomach cancer. Conclusions: Most cancer cases were in women, and one-third were in individuals with no health insurance cover. The most frequently occurring cancers were skin and prostate for males, and cervical and breast cancer for females, with most cancers being diagnosed in locally advanced stages. Leukaemia was the most common childhood cancer. This hospital-based cancer registry provides important information for the description of the behaviour of cancer in the local setting.
