Consecuencias oncológicas y perinatales del tratamiento conservador de la fertilidad en pacientes con cáncer endometrial tratadas con progestinas / Oncological and perinatal results of conservative treatment of fertility in patients with endometrial cancer treated with progestins

Resumen OBJETIVO: Estimar la tasa de respuesta completa y de embarazo en mujeres con cáncer endometrial en tratamiento conservador con progestinas. MATERIALES Y MÉTODOS: Estudio de cohorte, retrolectivo y transversal efectuado en el Instituto Nacional de Perinatología en mujeres con cáncer endometrial, en estadios tempranos, atendidas entre 2007 y diciembre de 2016. Criterios de inclusión: pacientes con límites de edad de 18 y 40 años, nulíparas, con deseo de fertilidad, haber sido tratadas con megestrol, DIU-levonorgestrel o progesterona micronizada durante seis meses. A todas las pacientes se les tomó una biopsia endometrial a los 6 y 12 meses. Se utilizó estadística descriptiva y comparaciones entre mediciones, χ2 o t de Student según la distribución de cada variable. RESULTADOS: Se incluyeron 11 pacientes con cáncer endometrial con edad promedio de 32 ± 2.4 años. La biopsia tomada a los seis meses fue: respuesta completa en 6/11, respuesta parcial en 2/11 y persistencia en 2/11; en una paciente no se tomó la biopsia a los seis meses por embarazo, no hubo casos de progresión. A los 12 meses de seguimiento hubo 5 respuestas completas, 2 parciales, 2 persistencias, 1 caso de progresión de la enfermedad y otro que suspendió el tratamiento. Se efectuaron 8 ciclos de FIV en 6 pacientes con tasa de embarazo de 25%. La duración del tratamiento fue de 19.3 ± 8 meses, el seguimiento total fue de 31.6 ± 13 meses. CONCLUSIONES: El tratamiento conservador de la fertilidad con progestinas en pacientes con cáncer endometrial, en etapas tempranas, es factible y seguro. El embarazo debe intentarse inmediatamente después de una respuesta completa.

Abstract OBJECTIVE: To estimate the complete response rate and pregnancy in women with endometrial cancer who have received conservative treatment with progestins. MATERIALS AND METHODS: Cohort, retrolective and transversal study carried out in the National Institute of Perinatology, in women with endometrial cancer in early stages between 2007 and December 2016. Including patients between 18-40 years, nulliparous, with desire for fertility. The progestins used were megestrol, IUD-levonorgestrel and micronized progesterone for six months. Endometrial biopsy was performed at 6 and 12 months; The result was classified as a complete, partial response, persistence or progression of the disease. Descriptive statistics and comparisons between baseline measurements at six and 12 months are used using student grid and / or t tests according to the distribution of each variable. It is a statistical program SPSS version 23 for Windows (Chicago, USA). RESULTS: 11 women with endometrial cancer were included. The average age of the women was 32 ± 2.4 years. Morbidity associated with hypothyroidism and type 2 diabetes mellitus. Six-month biopsy was: complete response 6/11 partial response 2/11 and persistence 2/11, in one patient the biopsy was not performed at 6 months by pregnancy, there were no cases of progression. At 12 months of follow-up, there were 5 complete responses, 2 partial responses, 2 persistences, 1 case of disease progression and one case that discontinued treatment. Eight cycles of IVF were performed in 6 patients with a pregnancy rate of 25%, the duration of treatment was 19.3 ± 8 months, the total follow-up was 31.6 ± 13 months. CONCLUSIONS: Conservative fertility therapy with progestins in women younger than 40 years old with early-stage endometrial cancer is feasible and secure in our institution. Pregnancy must be sought immediately after a full response to the cancer treatment. Our findings are similar to the ones found in our systematic review of the international bibliography.

Resumen Objetivo: Describir el esquema de tratamiento indicado a pacientes con cáncer y embarazo y las repercusiones perinatales. Materiales y métodos: Estudio retrospectivo, longitudinal, observacional y descriptivo de una cohorte simple de pacientes con diagnóstico de cáncer (corroborado por estudio histopatológico) y embarazo atendidas en el Instituto Nacional de Perinatología entre los meses de enero de 2009 a diciembre de 2014. Los datos se analizaron con el programa SPSS versión 20.0 con medidas de tendencia central, frecuencias, proporciones y desviación estándar. Resultados: Se incluyeron 47 pacientes con media de edad de 28.1 ± 7.3 años, el diagnóstico de cáncer se estableció en 46 pacientes, en promedio, a las 19.4 ± 8.5 semanas y en un caso en el puerperio tardío. Los cánceres más frecuentes fueron: 28% leucemia (n = 13), 26% mama (n = 12), 17% cuello uterino (n = 8) y 15% ovario (n = 7). Durante el embarazo 55% de las pacientes recibieron quimioterapia (n = 27) y 28% tratamiento quirúrgico (n = 13). Se obtuvieron 42 nacidos vivos (91%) de que: 53% fueron a término (n = 25), 22% pretérmino tardío (n = 10), 9% pretérmino moderado (n = 4) y 6% pretérmino extremo (n = 3). Se registraron 2 nacimientos inmaduros (4%), 3 abortos espontáneos (6%) y 3 muertes maternas indirectas (6%). Conclusiones: La cirugía y la quimioterapia durante el segundo trimestre del embarazo son seguras para la madre y el feto.

Abstract Objective: To describe the management and perinatal outcomes in patients with cancer and pregnancy. Materials and method: Retrospective, longitudinal, observational and descriptive study of a simple cohort of women with a diagnosis of Cancer (corroborated by histopathological study) and pregnancy from January 2009 to December 2014. The data was analyzed with the SPSS program version 20.0 with central tendency measures, frequencies, proportions and standard deviation. Results: We included 47 patients with an average age of 28.1 ± 7.3 years, the diagnosis of cancer was made in 46 patients on average at 19.4 ± 8.5 weeks and in a case in the late puerperium. The most frequent cancers were: 28% leukemia (n = 13), 26% breast (n = 12), 17% cervical (n = 8) and 15% ovarian (n = 7). During pregnancy 55% patients received chemotherapy (n = 27) and 28% surgical treatment (n = 13). We obtained 42 live births (91%) of which: 53% were full term (n = 25), 22% late preterm (n = 10), 9% moderate preterm (n=4) and 6% extreme preterm (n = 3). There were 2 immature births (4%), 3 miscarriages (6%) and 3 indirect maternal deaths (6%). Conclusions: Surgery and chemotherapy during the second trimester of pregnancy are safe for the mother and the fetus.

[Acute abdomen as a complication of a molar pregnancy]. / Abdomen agudo como complicación de un embarazo molar.

UNLABELLED: To report a case of bilateral ovarian torsion after a molar pregnancy. CLINICAL CASE: An 18 year old female was admitted for a 7 week molar pregnancy. A week after uterine evacuation the patient was readmitted to the emergency room with acute abdomen. Exploratory laparotomy revealed torsion and necrosis of both ovaries. A bilateral salpingo-oophorectomy was performed. The anatomopathology study confirms both ovaries with hyperrectio luteinalis and hemorrhagic infarct. Acute abdomen secondary to torsion and necrosis of thecalutein cysts can be a molar pregnancy-related complication.

Tumor phyllodes / Phyllodes tumours

El tumor phyllodes es una neoplasia fibroepitelial rara; constituye el 0.3 al 0.9% de tumores de mama y 2-3% de los tumores fibroepiteliales de mama. Puede presentarse a cualquier edad y no hay características confiables para predecir su comportamiento clínico. Se deben evaluar varios parámetros, incluyendo la celularidad estromal, atipia, mitosis, crecimiento estromal excesivo, infiltración de bordes y presencia o ausencia de necrosis. La mayor parte de estos tumores son benignos, pero hasta 30% pueden presentar tejido conectivo maligno. Las metástasis generalmente son hematógenas más que linfáticas y se presentan en un 13% de los casos. La disección de ganglios axilares generalmente no se recomienda. El tumor phyllodes benigno y maligno recurre de manera local en el 25%, por lo que se recomienda el seguimiento de los casos.

Phyllodes tumors is a rare fibroepithelial neoplasm; constitute about 0.3-0.9% of breast tumors and 2-3% of fibroepithelial breast tumors. They usually occur in middle-aged to elderly women but can occur at any age. No single feature is reliable to predict clinical behavior of phyllodes tumors. Several histological parameters should be evaluated, including stromal cellularity, atypia, mitoses, stromal overgrowth, infiltrative borders, and presence or absence of necrosis. Most of these tumors are benign, but up to 30% show malignant stroma. Metastases usually are hematogenous rather than lymphatic have been reported to occur at a rate of 13% as malignant phyllodes tumors usually spread by a hematogenous rather than a lymphatic route; axillary lymph node dissection is generally not recommended. The benign and malignant tumors phyllodes resort locally in 25% and follow up of patients is recomended.

[Conservative treatment of endometrial cancer as a way to preserve fertility. Five-year experience at Instituto Nacional de Perinatilogía Isidro Espinoza de los Reyes]. / Tratamiento conservador del cáncer de endometrio como una opción para preservar la fertilidad. Experiencia de cinco años en el Instituto Nacional de Perinatología Isidro Espinosa de los Reyes.

BACKGROUND: Progestins have been used in the treatment of advanced and metastatic endometrial cancer since the early 1960s. There is evidence that progestins can be used in fertility-preserving treatments in young women diagnosed with well-differentiated clinical stage 1A(EC1A) endometrioid type endometrial carcinoma. OBJECTIVE: Describe a fertility preservation treatment in women with primary infertility and EC1A endometrioid type endometrial carcinoma. PATIENTS AND METHODS: A historical cohort study. We analyzed 6 cases of women under 35 years assisted at the Oncology and Reproductive Medicine Department of the Instituto Nacional de Perinatologia of Mexico who met our inclusion criteria. Five women were treated with 500 mg medroxyprogesterone acetate (MPA) every other day; one woman was treated with 40 mg/day megestrol acetate (MGA). The treatment was continued to a maximum period of 11 months, provided that women gave good response to the treatment. The change in endometrial histology was assessed at four and six months of treatment. The primary endpoint was pathological complete response (CR). RESULTS: Follow-up time averaged 31 months; 66.6% of women responded to the initial hormone treatment; the remaining 33.4% responded to a second period of progesterone with histology in endometrial biopsy negative for cancer. Average response time was 6.8 months. Two patients had recurrence at an average of 19.5 months. Endometrial routine was performed with a disease-free interval of 15 to 24 months during which assisted reproductive technologies (ART) could be applied. Two patients achieved full-term pregnancy thanks to ART. The remaining patients did not continue with ART on their own initiative. CONCLUSIONS: In young women diagnosed with well-differentiated endometrioid EC1A carcinoma, the fertility-preserving treatment with progestin may be proposed together with strict selection and close monitoring of the patient.

[Hormone therapy effect in postmenopausal women with history of endometrial cancer]. / Efecto de la terapia hormonal en mujeres posmenopáusicas con antecedente de cáncer de endometrio.

BACKGROUND: The increase of endometrial cancer survivors' incidence let the question if the management of postmenopausal hormone therapy will increase the risk of carcinogenesis. OBJECTIVE: To determine the recurrence rate, in postmenopausal patients managed with hormonal therapy (HT) compared with patients without HT treated in El Instituto Nacional de Perinatologia Isidro Espinosa de los Reyes. PATIENTS AND METHOD: Retrospective, analytical, historical cohort. We analyzed 29 patients who met the inclusion criteria from January 1, 2000 to December 31, 2008 RESULTS: The average age for diagnosis of endometrial cancer was 45 years. 100% of the patients had surgical treatment (82.8% routine endometrial open approach, laparoscopic 17.2%). The 93% of patients had criteria to begin HT, however, was administered alone to 37% due to medical criteria, 36% received tibolona, 64% received estrogen with an average administration time of 39 and 54 months for each one without affecting disease-free period. Patients who received hormonal therapy had no recurrence of disease-free period of 58 months. There was only one patient with recurrence for which no hormonal therapy was administered. CONCLUSIONS: Patients who were under hormonal therapy did not modify the rate of endometrial cancer recurrence compared with those without HT. Although we cannot conclude irrefutably the safety of hormone therapy, based on biological knowledge and the results of this study, hormone therapy can be safely administered in stage I and II.

[Adnexal tumor and pregnancy: diagnosis and treatment]. / Tumor anexial y embarazo: diagnóstico y tratamiento.

BACKGROUND: The finding of adnexal masses during pregnancy is an exceptional event. Its reported incidence is less than 5% and most cases resolve spontaneously as the pregnancy progresses. OBJECTIVE: Describe a case series of patients with adnexal mass and pregnancy. MATERIAL AND METHODS: We retrospectively reviewed the medical records of patients who had diagnosis of pregnancy and adnexal over a period of five years. RESULTS: The incidence was 0.22%. The mean age was 26 +/- 7.3 years, mean gestational age was 17 +/- 6.6 weeks. The diagnosis was established by ultrasound (USG) in 95% of cases, 48% had cystic characteristics, the mean diameter of the tumor was 99 +/- 42 mm. Cistectomy was performed during pregnancy or trans-cesarean section in 30% and 58% of patients respectably. The mean tumor size was 118 mm (range 2 a 40 mm), weight 1,370 g (range 10 a 5,800 g). The most frequent histological diagnosis were serous cyst (40%), mature teratoma (28%), mucinous (6%), malignancy (4%). There were not complications related to the surgical procedure. CONCLUSIONS: The USG constitute a safe method for the diagnosis, but the image method with the highest positive predictive value is the MRI. Tumor markers (CA-125, AFP, GCH-B,DHL, ACE), are not useful during pregnancy. If the tumor doesn't achieve surgical criteria the recommended follow up is clinical observation and USG. If surgery is decided, it should be performed between 16 a 23 weeks of pregnancy, and it's recommended to send the tumor to histological diagnosis, in case of malignancy the surgery will continue according to the tumor stage. The time and delivery route will be decided by the obstetrician.

[Pregnancy after conservative management of endometrial cancer]. / Embarazo después del tratamiento conservador de cáncer de endometrio.

OBJECTIVE: To show the reproductive future of a case of endometrial cancer with conservative management. MATERIAL AND METHODS: a case report and literature review. 31 years old woman, with a history of infertility of three years and abnormal uterine bleeding of one year, diagnosed with well differentiated endometrial adenocarcinoma IA GI. Treatment was initiated with 500 mg of progesterone three times a week for 6 months, after an endometrial curettage reporting healthy endometrium, pregnancy was achieved with homologous artificial insemination after hysteroscopy and directed biopsy with laparoscopic control by assisted reproduction service. RESULTS: Exploratory laparotomy and cesarean section was performed at 38 weeks of pregnancy, giving a 3.340 g weight male with Apgar score 9/9. A review of abdominal cavity and an obstetric curettage were performed. Biopsies were taken from slides and peritoneal lavage, Neoplastic changes were not reported by pathology. CONCLUSIONS: Endometrial cancer is common in adult women and is increasingly affecting young women, associated with infertility, obesity and nulliparity. The treatment of choice: total hysterectomy with bilateral salpingooforectomy. The prognosis in well-differentiated early, and infertility, permits conservative management based on progestins, with good results, low recurrence rate and preserving fertility.

[Surgical approach of breast nodules during pregnancy]. / Abordaje quirúrgico de nódulos mamarios durante el embarazo.

BACKGROUND: Only in Mexico, about four thousand women die from breast cancer of which 11 thousand are diagnosed. Is undoubtedly the most malignant disease throughout the world are diagnosed each year as over one million every year and the figure grows. OBJECTIVE: To analyze the results of six years of experience in the therapeutic treatment of breast nodules during pregnancy which describes the treatment, establishing the diagnosis of breast biopsies, reported complications associated with obtaining the same. MATERIAL AND METHODS: We reviewed a database of search terms: pregnancy and breast nodule from January 1 2001 to December 31, 2006. RESULTS: Of the 20 lesions found, 19 were diagnosed with ultrasound as a solid type of injury, and as a mixed lesion. 18 biopsies were performed on pregnant women and post-natal period. In 10 (50%) patients, biopsy was performed by fine needle aspiration. In 13 of the patients were breast fibroadenoma, and only one was diagnosed with infiltrating ductal carcinoma le. In 10 patients operated lumpectomy was performed. A patient in modified radical mastectomy was performed because of the finding of ductal carcinoma. CONCLUSION: Our study was the Breast fibroadenoma lesion was found in more common. In our experience with the management of breast nodules in pregnancy, we can say that most of the lesions are benign, and usually are commonly encountered pathologies in nonpregnant women. In the case of diagnosing breast cancer, we must make the decision about the best treatment to offer the best possible forecasts.
