Preservação da fertilidade e dos ovários em mulheres com tumores anexiais benignos / Preservation of the fertility and the ovaries in women with benign adnexal tumors

OBJETIVO: Avaliar a preservação da fertilidade e dos ovários em mulheres submetidas à cirurgia por tumor anexial benigno. MÉTODOS: Para este estudo observacional com coleta prospectiva foram incluídas 206 mulheres operadas no CAISM-Unicamp de fevereiro de 2010 a janeiro de 2014. A preservação da fertilidade foi definida como tumorectomia ou anexectomia unilateral sem histerectomia em mulheres na pré-menopausa. A preservação ovariana foi considerada quando pelo menos um ovário ou parte dele foi preservado. RESULTADOS: Das 206 mulheres com tumores anexiais benignos, 120 (58%) estavam na pré-menopausa e 86 (42%) na pós-menopausa. Na pré-menopausa, foram encontrados 36 (30%) tumores de células germinativas, 31 (26%) neoplasias epiteliais e 11 (9%) do cordão sexual e estroma. Na pós-menopausa foram identificados 35 (41%) neoplasias epiteliais, 27 (31%) do cordão sexual e estroma e 8 (9%) de células germinativas. Entre as 36 mulheres com tumores ovarianos não neoplásicos, 21 (58%) apresentavam endometriomas e 8 (22%) cistos funcionais. Das 22 mulheres com tumores extra ovarianos, o leiomioma uterino foi o achado mais frequente (50%). Entre as pacientes com ≤35 anos, 26 (57%) foram submetidas à tumorectomia e 18 (39%) a anexectomia unilateral com preservação do útero e anexo contralateral. Mulheres com ≤35 anos foram mais frequentemente operadas por laparoscopia que esteve associada a maior taxa de preservação de fertilidade quando comparada com a laparotomia (p<0,01). Observou-se que 26 das pacientes submetidas à histerectomia com anexectomia (28%) bilateral estavam na pré-menopausa. CONCLUSÕES: Embora se observe uma tendência em realizar apenas tumorectomia em mulheres com ≤35 anos, uma proporção significativa de mulheres jovens ainda é ...

PURPOSE: To evaluate the sparing of fertility and ovaries in women submitted to surgical treatment for benign adnexal tumors. METHODS: Between February 2010 and January 2014, 206 patients were included in this observational study as they were submitted to surgical treatment for benign ovarian tumors at CAISM, a tertiary hospital. Fertility sparing surgery was defined as tumorectomy or unilateral salpingoophorectomy without hysterectomy in premenopausal women. Preservation of the ovary occurred when at least one ovary or part of it was mantained. RESULTS: Of the 206 women with benign tumors, 120 (58%) were premenopausal and 86 (42%) were postmenopausal. There were 36 (30%) ovarian germ cell tumors, 31 (26%) epithelial neoplasms and 11 (9%) sex-cord stromal tumors among premenopausal women. In the group of postmenopausal women, 35 (41%) epithelial neoplasms, 27 (31%) sex-cord stromal tumors and 8 (9%) ovarian germ cell tumors were identified. Among 36 women with non-neoplastic ovarian tumors, 21 (58%) had endometriomas and 8 (22%) functional cysts. Among 22 women with extra-ovarian tumors, uterine leiomyomatosis was the most frequent finding (50%). In the group of women who were ≤35 years old, 26 (57%) were treated by tumorectomy and 18 (39%) were submitted to unilateral salpingoophorectomy with sparing of the uterus and the contralateral ovary. Women who were ≤35 years old were more frequently operated by laparoscopy which was associated with a higher number of fertility sparing procedures when compared to laparotomy (p<0.01). Twenty-six (28%) women submitted to hysterectomy with bilateral salpingoophorectomy were premenopausal. CONCLUSION: Although there is a trend to perform only tumorectomy in women who are ≤35 years old, a significant number of young women is still treated by salpingoophorectomy. Among 36- to 45-year-old women, only 70% had their fertility spared, while 20% had both ovaries removed. ...

Dieta y cáncer gástrico en México y en el mundo / Diet and gastric cancer in Mexico and in the world

El cáncer gástrico (CG) es la cuarta causa de muerte por cáncer a nivel global. La dieta y el consumo de alcohol y tabaco, además de la infección por Helicobacter pylori determinan un gran número de casos de esta neoplasia. Algunos alimentos contienen sustancias que podrían influir en el proceso de carcinogénesis gástrica, aunque los mecanismos subyacentes no están completamente dilucidados. En México y el mundo, la disminución en el consumo de frutas, vegetales no feculentos y allium, leguminosas y alimentos fuente de selenio, así como el aumento en el consumo de sal, alimentos salados, salmuera y ahumados, chile, carnes procesadas y asadas o a la parrilla se han asociado respectivamente con un aumento de riesgo de CG. Con la evidencia disponible, se podrían desarrollar y evaluar programas para la prevención y control del CG.

Gastric cancer (GC) is the fourt leading cause of cancer death at global level. Diet, alcohol and tobacco, in addition to Helicobacter pylori infection, account for a large number of cases. Some substances contained in foods may influence GC carcinogenesis process; however, the underlying mechanisms have not been fully elucidated. In Mexico and worldwide, a low intake of fruits, non-starchy and allium vegetables, pulses, and foods containing selenium, as well as high intake of salt, salty, salted and smoked foods, chili pepper, processed and grilled/barbecued meats, have been respectively associated with an increased risk of GC. Based on the available evidence, programs for GC prevention and control could be developed and evaluated.
