Factors Associated with Parametrial Involvement in Endometrial Carcinoma in Patients Treated with Radical Hysterectomy.

INTRODUCTION: Describe factors associated with parametrial involvement, and how these factors modify the prognosis of patients with endometrial carcinoma treated with radical hysterectomy. METHODS: Observational study in which categorized patients according to those with and without parametrial involvement. A descriptive analysis and comparative analysis were performed for associations between parametrial spread and clinical, surgical, and pathology variables. RESULTS: We analyzed 85 patients, which 18 (21%) had parametrial involvement. Pathology factors associated with parametrial involvement were the endometrioid subtype, grade 3, and variants of poor prognosis (odds ratio (OR) 3.41, 95% CI 1.09-10.64; P = 0.035), myometrial invasion of over 50% (OR 7.76, 95% CI 1.65-36.44; P = 0.009), serosal involvement (OR 17.07, 95% CI 3.87-75.35; P < 0.001), ovarian metastasis (OR 5.15, 95% CI 1.36-19.46; P = 0.016), positive peritoneal cytology (OR 3.9, 95% CI 1.04-14.77; P = 0.044), and lymph node metastasis (OR 3.4; 95% CI 1.16-9.97; P = 0.026). Five-year disease-free survival was 74% (95% CI 57.4-85.4) for the group without parametrial spread and 50.8% (95% CI 22.7-73.4) for the group with parametrial spread (P = 0.001). Similarly, 5-year overall survival was 85.2% (95% CI 67.9-93.6) for the group without parametrial spread and 47.5% (95% CI 8.1-80.2) for the group with parametrial spread (P = 0.002). CONCLUSION: Factors associated with parametrial involvement were histologies of poor prognosis, tumors affecting uterine serosa, cervix, or spread beyond the uterus. Additionally, parametrial involvement directly affects prognosis by reducing overall survival, disease-free survival and increasing odds for recurrence.

Analysis of Mexican young women with primary ovarian insufficiency induced by gynaecological and haematological cancer management.

This was a retrospective study that included 114 women younger than 40 years with induced primary ovarian insufficiency. Patients who presented vasomotor symptoms had a higher proportion (26 [63.41%] versus 58 [79.45%], OR 2.23, 95% CI 0.95-5.23, p = .065) to initiate hormone replacement therapy. Vasomotor symptoms were present in patients with ovarian cancer (OR 0.27, 95% CI 0.09-0.8, p = .18), haematologic cancer (OR 0.11, 95% CI 0.2-0.65, p = .014), radiotherapy (OR 2.62, 95% CI 1.04-6.54, p = .039) and chemotherapy with radiotherapy (OR 2.72, 95% CI 1.01-7.35, p = .049). Having ovarian or haematological cancer, being managed with radiotherapy and/or chemotherapy, and having follicle-stimulating hormone parameters higher than 35 mUI/mL are factors that significantly increase the risk of presenting vasomotor symptoms.Impact StatementWhat is already known on this subject? In young women with cancer, induced primary ovarian insufficiency can result as an ovarian surgery or as an adverse effect of chemotherapy or radiotherapy. Regardless of aetiology, patients are going to manifest early climacteric symptoms with an increased risk for cardiovascular disease, metabolic syndrome and osteoporosis.What do the results of this study add? Patients who presented vasomotor symptoms had initially a higher proportion of hormone replacement therapy. Patients that were treated exclusively with radiotherapy or with chemotherapy and concomitant radiotherapy have a significantly increased risk to manifest vasomotor symptoms.What are the implications of these findings for clinical practice and/or future research? Having ovarian or haematological cancer, being managed with radiotherapy and/or chemotherapy and having follicle-stimulating hormone parameters higher than 35 mUI/mL are factors that significantly increase the risk of presenting vasomotor symptoms.

Nutritional status in patients with COVID-19 and cancer: the experience of the National Cancer Institute in Mexico.

INTRODUCTION: Background: nutritional status might vary according to different underlying illnesses such as cancer or infectious diseases, including COVID-19. In this context, data from developing countries remain scarce. Objectives: the objective of this study was to assess the nutritional status and outcomes of Mexican cancer patients diagnosed with COVID-19 at a tertiary care center. Methods: this was a retrospective study including 121 consecutive cancer patients diagnosed with COVID-19 at the National Cancer Institute, Mexico City, during four months. Results: the most frequent oncological diagnoses were gynecological (19 %) and hematological (17 %). Most patients were overweight (35 %). In the univariate analysis, ≥ 65 years, intubation, hypoalbuminemia, high creatinine, lymphopenia, nutrition-impact symptoms, and ECOG 2-4 were statistically associated with lower survival. The median survival of the cohort was 41 days. Conclusions: to our best knowledge, this is the first study of its kind performed in Mexico, and as other studies from other regions, our results might aid in identifying cancer patients most at risk for severe COVID-19, and could be potentially useful to enhance public health messaging on self-isolation and social distancing among Mexican cancer patients.

INTRODUCCIÓN: Antecedentes: el estado nutricional puede variar según las diferentes enfermedades subyacentes, como el cáncer o las enfermedades infecciosas, por ejemplo, la COVID-19. En este contexto, los datos de los países en desarrollo siguen siendo escasos. Objetivos: el objetivo de este estudio fue evaluar el estado nutricional y los resultados de pacientes mexicanos con cáncer diagnosticados de COVID-19 en un centro de atención terciaria. Métodos: se trata de un estudio retrospectivo que incluyó a 121 pacientes consecutivos con cáncer diagnosticados de COVID-19 en el Instituto Nacional del Cáncer de la Ciudad de México durante cuatro meses. Resultados: los diagnósticos oncológicos más frecuentes fueron los ginecológicos (19 %) y hematológicos (17 %). La mayoría de los pacientes tenían sobrepeso (35 %) y obesidad (31 %). En el análisis univariado, ≥ 65 años, intubación, hipoalbuminemia, creatinina alta, linfopenia, síntomas de impacto nutricional y ECOG 2-4 se asociaron estadísticamente con una menor supervivencia. La mediana de supervivencia de la cohorte fue de 41 días. Conclusiones: hasta donde sabemos, este es el primer estudio de este tipo realizado en México y, al igual que otros estudios de otras regiones, nuestros resultados podrían ayudar a identificar a los pacientes con cáncer y mayor riesgo de COVID-19 grave; también podrían ser potencialmente útiles para mejorar los mensajes de salud sobre el autoaislamiento y el distanciamiento social entre los pacientes mexicanos con cáncer.

Association of p16 and Ki-67 with Risk of Recurrence in Previously Treated Cervical High-Grade Squamous Intraepithelial Lesions.

OBJECTIVE: Our main objective was to assess the association between the markers p16 and Ki-67 and recurrence of disease in patients previously treated for cervical high-grade squamous intraepithelial lesion (HSIL). DESIGN: This is a case-control study at the National Cancer Institute conducted between 2005 and 2015. Of the patients with a pathologically confirmed diagnosis of HSIL, 107 cases were selected. They were divided into 2 groups: 28 cases with recurrence after treatment and a control group of 79 patients without recurrence. We identified clinical, pathological, and treatment variables. METHODS: Two experienced pathologists performed immunohistochemical analysis of biomarkers; they agreed on their interpretation, and we calculated the odds ratios (ORs) associated with recurrence. For group comparisons, we used the Wilcoxon signed-rank, χ2, or Fisher's exact test, depending on the type of variable. We conducted logistic regression models to estimate ORs and determine the factors associated with recurrence. The recurrence-free period was defined as the time frame between conization and either recurrence of disease or the last date the patient was seen. We used Kaplan-Meier plots to visualize survival curves and log-rank tests to compare the curves. We established a p value <0.05 as statistically significant. RESULTS: After pathologists performed immunohistochemical analysis, they achieved an agreement level of 83.7% for p16 and 60% for Ki-67. We did not find an association between recurrence and either p16 expression (p = 0.69) or the percentage of Ki-67 expression (p = 0.71). The recurrence-free period analysis did not reveal a difference in p16 expression (p = 0.57) nor in the percentage of Ki-67 expression in the 3-tiered scale (p = 0.56). LIMITATIONS: Our main limitation was a reduced sample size. CONCLUSION: We found no association between p16 and Ki-67 positivity and the risk of recurrence in previously treated HSIL.

Diagnostic performance of intraoperative assessment in grade 2 endometrioid endometrial carcinoma.

BACKGROUND: Endometrial carcinoma is the most common gynecologic malignancy in developed countries. Grade 2 carcinoma is associated with pelvic lymph-node metastasis, depending on selected risk factors. Intraoperative assessment (IOA) can identify patients at risk for lymph node metastasis who should undergo staging surgery. Our objective was to establish the diagnostic precision of IOA in determining the need for surgical staging in grade 2 endometrioid endometrial carcinoma. METHODS: Two hundred twenty-two patients underwent IOA. Results were compared to the final pathology report. The accuracy of the IOA parameters was calculated. Variables were evaluated in patients with positive versus negative IOA. Overall and disease-free survivals were calculated according to IOA, lymphadenectomy, and nodal metastasis. RESULTS: IOA was positive in 80 patients. It showed an accuracy of 76.13% when compared with the postoperative assessment. The best individual parameter was myometrial invasion. Nodal metastasis was observed in 16 patients in the positive IOA group and 7 patients in the negative group. Patients with lymph node metastasis had a 5-year overall survival rate of 80.9%, whereas patients without metastasis had a 5-year overall survival rate of 97.9%. CONCLUSIONS: IOA is an adequate tool to identify high-risk patients in grade 2 endometrial carcinoma. Myometrial invasion is the individual parameter that yields the highest diagnostic precision.

What is the impact of radical hysterectomy on endometrial cancer with cervical involvement?

BACKGROUND: When endometrial carcinoma invades the cervical stroma, overall survival and disease-free survival decrease. However, it is still controversial whether patients in suspected stage II should be treated with radical hysterectomy. The goal of this study is to describe the role of radical hysterectomy in patients with endometrial carcinoma and cervical involvement. METHODS: This was a retrospective cohort study were a total of 239 patients with endometrial carcinoma with cervical involvement from Mexico City's National Cancer Institute were divided according to the type of hysterectomy, and the outcomes were compared using statistical analysis. RESULTS: The 5-year overall survival was 75.76% for the simple hysterectomy group and 89.19% for the radical hysterectomy group, without achieving statistical significance. The 5-year disease-free survival was 72.95% for the simple hysterectomy group and 64.31% for the radical hysterectomy group, without achieving statistical significance. Radicality was associated with longer surgical times, intraoperative complications, and bleeding over 500 ml. CONCLUSIONS: In patients with endometrial carcinoma with cervical involvement, radical hysterectomy does not improve prognosis or alter adjuvant therapy.

Role of optimal cytoreduction in patients with dysgerminoma.

BACKGROUND: Dysgerminomas are malignant ovarian germ-cell tumors that typically affect young women. Although these tumors have an excellent response to chemotherapy, surgery is an integral part of primary treatment. OBJECTIVE: To evaluate outcomes of initial cytoreduction in patients diagnosed with dysgerminomas. METHODS: Patients who underwent primary cytoreductive surgery for ovarian dysgerminoma between January 1985 and December 2013 were identified and included in the study. A comparison was made between patients who underwent optimal versus sub-optimal cytoreduction. Descriptive, comparative statistics and odds ratios were used to establish an association. Survival curves were performed with the Kaplan-Meier method and compared using a log-rank test. A value of p<0.05 was used to establish a statistical difference. RESULTS: A total of 180 patients with a histologically confirmed dysgerminoma were included in the analysis. A subsection of 37 patients in stages III/IV were analyzed. The median age at diagnosis was 21 years (IQR 18-26). Histologically, 166 (92.2%) patients had pure dysgerminomas, whereas the rest had mixed histologies. The median tumor size was 18 (IQR 12-22) cm. In all stages, factors associated with optimal cytoreduction, were higher lactate dehydrogenase levels (OR=1.01; p=0.03), higher CA125 levels (OR=1.01; p=0.04), receiving adjuvant chemotherapy (OR=0.22; p<0.01), or undergoing treatment in a specialized institution (OR=12.68; p<0.01). Patients in stages III/IV, initially managed outside our institution were less likely to be taken for cytoreduction (OR=16.88; p=0.013). Other factors, including age (OR=1.02; p=0.39), pelvic lymph-node positivity (OR=2.24; p=0.36), pregnancy during follow-up (OR=0.91: p=0.80), or recurrence of disease (OR=1.93; p=0.23) were found to be similar in both groups. Overall survival was higher in optimally cytoreducted patients (100% vs 95.7%; p=0.032) including all stages, but not if considering only stages III/IV (100% vs 90%, p=0.186); disease-free survival was the same for both groups regardless of stage (94.3% vs 91.1%; p=0.36). CONCLUSION: Patients with optimal surgeries were most likely to be treated in referral centers. Initial residual disease did not significantly alter recurrence, progression, disease-free survival, or overall survival.

Morbidity and mortality of cytoreductive surgery with hyperthermic intraperitoneal chemotherapy: national cancer institute, Mexico city, Mexico.

Peritoneal carcinomatosis (PC) is generally considered a lethal disease, with a poor prognosis. Cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) has emerged as a new approach for peritoneal surface disease. This study investigated the early experience with this combined modality treatment at a single institute. From January 2007 to March 2010, 24 patients were treated After aggressive CS, with HIPEC (cisplatin 25 mg/m(2)/L and mitomycin C 3.3 mg/m(2)/L was administered for 90-minutes at 40.5° C). These data suggest that aggressive CRS with HIPEC for the treatment of PC may result in low mortality and acceptable morbidity. Rigorous patient selection, appropriate and prudent operative procedures were associated with encouraging results in our experience.

[The first Mexican consensus of endometrial cancer. Grupo de Investigación en Cáncer de Ovario y Tumores Ginecológicos de México]. / Primer consenso Mexicano de cancer de endometrio.

INTRODUCTION: Endometrial cancer (EC) is the second most common gynecologic malignancy worldwide in the peri and postmenopausal period. Most often for the endometrioid variety. In early clinical stages long-term survival is greater than 80%, while in advanced stages it is less than 50%. In our country there is not a standard management between institutions. GICOM collaborative group under the auspice of different institutions have made the following consensus in order to make recommendations for the management of patients with this type of neoplasm. MATERIAL AND METHODS: The following recommendations were made by independent professionals in the field of Gynecologic Oncology, questions and statements were based on a comprehensive and systematic review of literature. It took place in the context of a meeting of four days in which a debate was held. These statements are the conclusions reached by agreement of the participant members. RESULTS: Screening should be performed women at high risk (diabetics, family history of inherited colon cancer, Lynch S. type II). Endometrial thickness in postmenopausal patients is best evaluated by transvaginal US, a thickness greater than or equal to 5 mm must be evaluated. Women taking tamoxifen should be monitored using this method. Abnormal bleeding in the usual main symptom, all post menopausal women with vaginal bleeding should be evaluated. Diagnosis is made by histerescopy-guided biopsy. Magnetic resonance is the best image method as preoperative evaluation. Frozen section evaluates histologic grade, myometrial invasion, cervical and adnexal involvement. Total abdominal hysterectomy, bilateral salpingo oophorectomy, pelvic and para-aortic lymphadenectomy should be performed except in endometrial histology grades 1 and 2, less than 50% invasion of the myometrium without evidence of disease out of the uterus. Omentectomy should be done in histologies other than endometriod. Surgery should be always performed by a Gynecologic Oncologist or Surgical Oncologist, laparoscopy is an alternative, especially in patients with hypertension and diabetes for being less morbid. Adjuvant treatment after surgery includes radiation therapy to the pelvis, brachytherapy, and chemotherapy. Patients with Stages III and IV should have surgery with intention to achieve optimal cytoreduction because of the impact on survival (51 m vs. 14 m), the treatment of recurrence can be with surgery depending on the pattern of relapse, systemic chemotherapy or hormonal therapy. Follow-up of patients is basically clinical in a regular basis. CONCLUSIONS: Screening programme is only for high risk patients. Multidisciplinary treatment impacts on survival and local control of the disease, including surgery, radiation therapy and chemotherapy, hormonal treatment is reserved to selected cases of recurrence. This is the first attempt of a Mexican Collaborative Group in Gynecology to give recommendations is a special type of neoplasm.

Prognostic significance of pathological response after neoadjuvant chemotherapy or chemoradiation for locally advanced cervical carcinoma.

BACKGROUND: Cisplatin-based chemoradiation is the standard of care for locally advanced cervical cancer patients; however, neoadjuvant modalities are currently being tested. Neoadjuvant studies in several tumor types have underscored the prognostic significance of pathological response for survival; however there is a paucity of studies in cervical cancer investigating this issue. METHODS: Four cohorts of patients with locally advanced cervical carcinoma (stages IB2-IIIB); included prospectively in phase II protocols of either neoadjuvant chemotherapy with 1) cisplatin-gemcitabine, 2) oxaliplatin-gemcitabine, 3) carboplatin-paclitaxel or 4) chemoradiation with cisplatin or cisplatin-gemcitabine followed by radical hysterectomy were analyzed for pathological response and survival. RESULTS: One-hundred and fifty three (86%) of the 178 patients treated within these trials, underwent radical hysterectomy and were analyzed. Overall, the mean age was 44.7 and almost two-thirds were FIGO stage IIB. Pathological response rates were as follows: Complete (pCR) in 60 cases (39.2%), Near-complete (p-Near-CR) in 24 (15.6 %) and partial (pPR) in 69 cases (45.1%). A higher proportion rate of pCR was observed in patients treated with chemoradiotherapy (with cisplatin [19/40, 47.5%]; or with cisplatin-gemcitabine [24/41, 58.5%] compared with patients receiving only chemotherapy, 6/23 (26%), 3/8 (37.5%) and 8/41 (19.5%) for cisplatin-gemcitabine, oxaliplatin-gemcitabine and carboplatin-paclitaxel respectively [p = 0.0001]). A total of 29 relapses (18.9%) were documented. The pathological response was the only factor influencing on relapse, since only 4/60 (6.6%) patients with pCR relapsed, compared with 25/93 (26.8%) patients with viable tumor, either pNear-CR or pPR (p = 0.001). Overall survival was 98.3% in patients with pCR versus 83% for patients with either pNear-CR or pPR (p = 0.009). CONCLUSION: Complete pathological response but no Near-complete and partial responses is associated with longer survival in cervical cancer patients treated with neoadjuvant chemotherapy or chemoradiotherapy.

Multimodal treatment of locally advanced cervical cancer.

BACKGROUND: Radiation therapy with concomitant chemotherapy is the standard treatment for locally advanced cervical cancer. In Mexico, most patients are still treated with radiation therapy alone. The aim of this work was to demonstrate that results obtained with combined treatments in the Mexican population are similar to those reported in the literature. METHODS: Survival was analyzed in three sequential phase II studies of combined treatment: neoadjuvant chemotherapy followed by surgery (NEOCT+Sx) -February to July 1999; concomitant chemoradiotherapy (CT/RT) -August to December 1999; and neoadjuvant chemotherapy followed by surgery plus adjuvant chemoradiotherapy (NEOCT+Sx+CT/RT) -December 2000 to June 2001. These results were compared with a historical control group treated with radiation therapy alone between September and December 1998. The Kaplan-Meier product-limit method, log-rank test and Cox proportional hazards model were used for analysis. RESULTS: Results showed that the three combined modalities significantly reduced the risk of death. Treatment with NEOCT+Sx reduced the risk to 0.452 (95% CI 0.246-0.830), p=0.010. The risk reduction with CT/RT was 0.408 (95% CI 0.218-0.762), p=0.005, and for the group of patients receiving NEOCT+Sx+CT/RT risk was reduced to 0.365 (95% CI 0.169-0.787), p=0.010. The corresponding absolute survival benefit was 14% for patients in stages IB2-IIA, 24% for IIB, and 21% for stage IIIB. CONCLUSIONS: Within the limitations of a non-randomized study, our results are in agreement with those obtained from published randomized phase III trials which state that radiation therapy alone is a suboptimal treatment for locally advanced cervical cancer; hence, patients should receive cisplatin-based chemoradiotherapy as a standard treatment.

Pathologic response and toxicity assessment of chemoradiotherapy with cisplatin versus cisplatin plus gemcitabine in cervical cancer: a randomized Phase II study.

PURPOSE: To compare gemcitabine and cisplatin (GC) with cisplatin (C) concurrent with radiotherapy in International Federation of Gynecology and Obstetrics Stage IB2, IIA, and IIB cervical carcinoma in a preoperative setting. The main endpoints were the pathologic response rate and toxicity. METHODS AND MATERIALS: A total of 83 patients were randomized to either C or GC. Treatment consisted of six doses of cisplatin at 40 mg/m(2) every week for Arm 1 (C) and six doses of gemcitabine at 125 mg/m(2) plus cisplatin at 40 mg/m(2) every week for or Arm 2 (GC) Both regimens were administered concurrent with 50 Gy of external beam radiotherapy in 2-Gy fractions for 5 weeks. After chemoradiotherapy, patients underwent radical hysterectomy. RESULTS: All 83 patients were studied for toxicity and 80 for response. The complete pathologic response rate in the C arm and GC arm was 55% (95% confidence interval, 35.5-73%) and 77.5% (95% confidence interval, 57-90%; p = 0.0201). Among those with a partial response, 7 patients each had high and intermediate-high risk factors for recurrence in their surgical specimens in the C arm vs. 2 and 3 patients, respectively, with these characteristics in the CG arm. The number of weekly doses and the dose intensity of GC were lower than for C. The time to complete external beam radiotherapy also favored the C arm. The CG combination produced greater GI and hematologic toxicity. CONCLUSION: The radiosensitizing combination of GC achieved a greater pathologic response rate than C in the treatment of cervical cancer.

A phase I study of carboplatin concurrent with radiation in FIGO stage IIIB cervix uteri carcinoma.

PURPOSE: Chemoradiation based on cisplatin, most commonly weekly, is the standard treatment of locally advanced cervical cancer; however, the nephrotoxic potential and the requirement for hydration of cisplatin somewhat restrains its use. The objective of this study was to determine the recommended dose of carboplatin when administered weekly during pelvic radiation (RT). METHODS AND MATERIALS: Twenty-four histologically proven, International Federation of Gynecology and Obstetrics Stage IIIB patients were treated with standard pelvic RT concurrently with six weekly applications of carboplatin at the following dose levels: 100 mg/m(2), 116 mg/m(2), 133 mg/m(2), and 150 mg/m(2). Six patients per level were treated. Acute toxicity was assessed according to the Radiation Therapy Oncology Group Acute Radiation Morbidity Scoring Criteria. The recommended dose was defined as the one that was one level below the level at which dose-limiting toxicity was present in more than one-third of patients. RESULTS: Between September 2001 and July 2002, 24 patients were accrued. All but two completed external beam radiotherapy and intracavitary treatment. The treatment was well tolerated. The median number of weekly applications of carboplatin was six, and the mean dose to points A and B was 85.6 Gy (range 75.2-91.6) and 62.9 Gy (range 58.2-74.6), respectively. RT was delivered within 41.7 days (range 33-70). Dose-limiting toxicity (leukopenia and/or neutropenia) was present in 50% of patients treated at the higher dose level (150 mg/m(2)). At the recommended dose of 133 mg/m(2), 33% of patients presented with Grade 3 leukopenia. At treatment completion, 75% of patients had a complete clinical response. CONCLUSION: Carboplatin at 133 mg/m(2), weekly for 6 weeks, is a well tolerated and effective radiosensitizer in cervical cancer patients.

Experiencia preliminar con el reservorio urinario ileocolónico tipo Miami en la práctica de Ginecología Oncológica / Preliminary experience with the continenent ileocolonic urinary reservoir (Miami pouch) in gynecologic oncology

OBJETIVOS. Por años hemos realizado conductos ileales y sigmoideos para la reconstrucción urinaria durante la exenteración pélvica. Los reservorios urinarios continentes los están reemplazando en nuestra institución. MÉTODOS. Hemos construido 26 reservorios tipo Miami en pacientes a quienes se les ha realizado una exenteración pélvica anterior o total por cáncer ginecológico primario o recurrente, o cistectomía por cistitis hemorrágica, reparación de fístulas urovaginales o en substitución de un conducto ileal. Veinticuatro de estas pacientes habían recibido radioterapia por un tumor ginecológico. RESULTADOS. El porcentaje de pacientes que lograron continencia completa fue de 95,6 por ciento. En el 92,3 por ciento de las pacientes no hubo obstrucción o reflujo. No se observó incremento en la morbimortalidad del procedimiento principal y fue posible realizar procedimientos reconstructivos adicionales como la preservación del esfínter anal con anastomosis colo-rectal baja. CONCLUSIONES. El reservorio ileocolónico tipo Miami es una forma continente de derivación urinaria de baja presión, siendo el mecanismo de continencia fácil de construir. La mayoría de ginecólogos oncólogos deberían estar capacitados para poder ofrecer un reservorio ileocolónico continente como una forma electiva de derivación urinaria (AU)

Exenteración pélvica en el Instituto Nacional de Cancerología / Pelvic exenteration in the Instituto Nacional de Cancerologia

Introducción. Desde 1948, la exenteración pélvica ha sido la alternativa de tratamiento en el rescate para pacientes con recurrencia por cáncer en la pelvis, sobre todo de tipo ginecológico. El procedimiento original ha sido modificado infinidad de ocasiones en un intento por mejorar el estado general y la calidad de vida de las pacientes sometidas a esta intervención. Objetivo. Efectuamos una revisión de la literatura y transmitimos la evaluación sobre el abordaje integral de las pacientes con recurrencia por cáncer ginecológico, con especial énfasis en el manejo perioperatorio estándar de las pacientes candidatas a esta intervención. Material y métodos. Revisión de la literatura, y análisis crítico de los departamentos involucrados, en el manejo perioperatorio de estas pacientes. Se describen con detalle desde el proceso de selección de las mujeres candidatas, rutas de manejo, monitoreo, evaluaciones preoperatorias, técnica quirúrgica más comúnmente empleada en el Instituto Nacional de Cancerología, hasta los cuidados posoperatorios y seguimiento de las pacientes. Resultados. Resultados. La selección meticulosa de las pacientes candidatas al procedimiento se inicia desde la primera entrevista con evaluación del entorno de la pacientes, soporte familiar, factibilidad económica y decision final por parte de la paciente. Participación de un equipo quirúrgico y de enfermería, multidisplinario, familiarizado con el procedimiento y colaborando sincrónicamente en las fases exenterativa y de reconstrucción. Apego y compromiso en la vigilancia estrecha del posoperatorio y evolución a corto, mediano y largo plazo de las pacientes. Conclusiones. El éxito de este tipo de procedimiento requiere pacientes bien seleccionadas, en centro oncológicos de experiencia, participación multidisciplinaria durante la resección quirúrgica, pero sobre todo del compromiso real por parte del equipo quirúrgico y de enfermería durante el manejo posoperatorio

Cáncer de endometrio: abordaje diagnóstico y terapéutico: experiencia en el Instituto Nacional de Cancerología / Endometrial carcinoma: diagnostic therapeutic approach: experience at Instituto Nacional de Cancerologia Mexico

El cáncer de endometrio en nuestro país ocupa el tercer lugar entre las neoplasias ginecológicas; su incidencia continúa incrementándose. Por fortuna, el mayor número de casos se diagnostica en etapa confinada al útero; sin embargo, es necesario seguir un adecuado abordaje diagnóstico y terapéutico que nos permita obtener los buenos resultados que generalmente se obtienen en esta neoplasia. Es importante distinguir entre factores de bajo y alto riesgo para diseminación extrauterina de la enfermedad que nos indique a qué pacientes, ya previamente intervenidas de histerectomía y salpingo-ooforectomía bilateral fuera de nuestro Instituto, será necesario reintervenir para completar la estadificación o a quiénes podría indicarse mantener en vigilancia o algún tipo de manejo adyuvante. Asimismo, en las pacientes vírgenes al tratamiento, estos factores de riesgo nos indican a quiénes practicar una disección selectiva de ganglios pélvicos o paraaórticos y, a la luz de los resultados patológicos de esta estadificación, a quiénes justificar un manejo adyuvante con radioterapia y, en pacientes con enfermedad extrauterina, a quiénes justificar tratamiento con quimio y hormonoterapia. En nuestra institución tratamos de seguir en forma estándar un abordaje diagnóstico y terapéutico; sin embargo, con frecuencia nos enfrentamos con casos que requieren de una decisión de manejo tomada en base a criterios individualizados

Melanoma de la vulva. Informe de 10 casos y revisión de la literatura / Vulvar melanoma: Case reports and literature review

El melanoma de la vulva representa menos del 10 por ciento de los melanomas en la mujer y de todas las neoplasias de la vulva en general. Su rareza no permite establecer conductas propias de manejo quirúrgico y/o adyuvante, por lo que las estrategias básicamente se han tomado de la experiencia con el tratamiento del carcinoma epidermoide de la vulva y del melanoma cutáneo. Presentamos una serie de 10 mujeres con melanoma de vulva tratadas en el Instituto Nacional de Cancerología durante el período de 1986 a 1997. La mayoría se encontraban en etapas clínicas avanzadas (un caso en estadio I, dos en estadio II, seis en estadio III y una estadio IV), por lo que requirieron procedimientos quirúrgicos radicales. A seis mujeres se les trató con disección ganglionar inguinofemoral y a tres exclusivamente con exición local radical; la enferma restante rechazó el tratamiento. La morbilidad global fue del 35 por ciento. La mediana de control de la enfermedad fue de 7.3 meses. El curso inicialmente asintomático, la idiosincrasia de las pacientes y, muy posiblemente, el que en su mayoría fueran mujeres seniles retrasaron el diagnóstico y favoreció la progresión de las lesiones. Recomendamos el manejo conservador en las pacientes con melanoma de la vulva. En los casos de tumores con profundidad mayor de 1.5 mm debe efectuarse disección inguinofemoral superficial de manera electiva

Carcinoma epidermoide originado en teratoma quístico maduro de ovario. Informe de dos casos y revisión de la literatura / Epidermoid carcinoma derived from mature cystic teratoma of the ovary. Two case presentation and literature review

La frecuencia del desarrollo de malignidad en un teratoma quístico maduro de ovario es de 1-2 por ciento. La mayoría de los casos informados ocurren en mujeres posmenopaúsicas. En este artículo se comunican dos casos de carcinoma epidermoide originado en un teratoma quístico maduro de ovario, uno de los cuales se presentó en una mujer joven. En el otro caso podemos sustentar que el origen del componente carcinomatoso se encuentra en el epitelio columnar y en la epidermis de los tejidos propios del teratoma

Linfoma primario de la glándula mamaria: lesión linfoepitelial asociada a linfoma maligno: reporte de un caso y revisión de la literatura / Primary breast lymphoma: lymphoepithelial lesion associated to malignant lymphoma

Los linfomas primarios de la mama son lesiones raras. Algunas veces son confundidos histológicamente con adenocarcinomas. En la literatura se refieren variantes de linfoma no-Hodgkin y enfermedad de Hodgkin primarias de la mama. Por otro lado, recientemente se han descrito linfomas extraganglionares asociados a tejido linfoide nativo de las mucosas en varios órganos, entre los que se encuentran: las glándulas mamaria, próstata, parótida, y órganos con pulmón y tubo digestivo. estas entidades se caracterizan por la presencia de una lesión linfoepitelial.
