Abstract
Fucosyltransferases (Fut) regulate the fucosylation process associated with tumorogenesis in different cancer types. Ascitic fluid (AF) from patients diagnosed with advanced stage of epithelial ovarian cancer (EOC) is considered as a dynamic tumor microenvironment associated with poor prognosis. Previous studies from our laboratory showed increased fucosylation in SKOV-3 and OVCAR-3, cancer-derived cell lines, when these cells were incubated with AFs derived from patients diagnosed with EOC. In the present work we studied three fucosyltransferases (Fut 2, Fut 4, and Fut 8) in SKOV-3, OVCAR-3 and CAOV-3 cell lines in combination with five different AFs from patients diagnosed with this disease, confirming that all tested AFs increased fucosylation. Then, we demonstrate that mRNAs of these three enzymes were overexpressed in the three cell lines under treatment with AFs. SKOV-3 showed the higher overexpression of Fut 2, Fut 4, and Fut 8 in comparison with the control condition. We further confirmed, in the SKOV-3 cell line, by endpoint PCR, WB, and confocal microscopy, that the three enzymes were overexpressed, being Fut 4 the most overexpressed enzyme compared to Fut 2 and Fut 8. These enzymes were concentrated in vesicular structures with a homogeneous distribution pattern throughout the cytoplasm. Moreover, we found that among the three enzymes, only Fut 4 was located inside the nuclei. The nuclear location of Fut 4 was confirmed for the three cell lines. These results allow to propose Fut 2, Fut 4, and Fut 8 as potential targets for EOC treatment or as diagnostic tools for this disease.

Abstract
Cervical cancer (CC) is tightly related to a low Human Development Index. Mexico is an upper-middle-income country with 126 million inhabitants, and its public health system aims to provide universal health coverage. Currently, employment-based social insurance covers approximately 60% of the population, and the scope of the remaining 40% is on course via the "IMSS-Bienestar" Institute. However, the annual government spending on health remains at 3% of the Gross Domestic Product, which is well below the 6% recommended by the Organization for Economic Cooperation and Development. CC is the second in incidence and mortality among women. Regarding primary prevention with the Human Papilloma Virus-vaccine, the current coverage for girls aged 9 to 14 years is only around 7%. Among secondary prevention with screening, the program is yet to cover the total number of women at risk; nevertheless, the age-standardized CC mortality rate has decreased from 12 per 100,000 women in 1979 to 5.7 per 100,000 women in 2020 due in part to increased screening coverage. Still, around two-thirds of patients present with locally advanced disease at diagnosis. Data from our country demonstrate that even socially disadvantaged CC patients achieve "standard" survival outcomes if treatment is granted. Nevertheless, there is a shortage in almost every aspect regarding CC treatment, including oncologists, chemotherapy units, medical physicists, radiation technicians, and both teletherapy and brachytherapy facilities. In conclusion, advances in the public health system in Mexico are urgently required to achieve CC control and reduce the mortality from this neoplasia that mainly targets socially disadvantaged women.

Abstract
Background: Ovarian cancer (OC) is gynecologic cancer with the highest mortality rate. It is estimated that 13–17% of ovarian cancers are due to heritable mutations in BRCA1 and BRCA2. The BRCA1 (BRCA1-Del ex9-12) Mexican founder mutation is responsible for 28–35% of the cases with ovarian cancer. The aim was to describe the PFS of OC patients treated with olaparib, emphasizing patients carrying the Mexican founder mutation (BRCA1-Del ex9-12). Methods: In this observational study, of 107 patients with BRCAm, 35 patients were treated with olaparib from November 2016 to May 2021 at the Ovarian Cancer Program (COE) of Mexico; patient information was extracted from electronic medical records. Results: Of 311 patients, 107 (34.4%) were with BRCAm; 71.9% (77/107) were with BRCA1, of which 27.3% (21/77) were with BRCA1-Del ex9-12, and 28.1% (30/107) were with BRCA2 mutations. Only 35 patients received olaparib treatment, and the median follow-up was 12.87 months. The PFS of BRCA1-Del ex9-12 was NR (non-reach); however, 73% of the patients received the treatment at 36 vs. 11.59 months (95% CI; 10.43–12.75) in patients with other BRCAm (p = 0.008). Almost 50% of patients required dose reduction due to toxicity; the most frequent adverse events were hematological in 76.5% and gastrointestinal in 4%. Conclusion: Mexican OC BRCA1-Del ex9-12 patients treated with olaparib had a significant increase in PFS regardless of the line of treatment compared to other mutations in BRCA.

Abstract
Endometrial cancer (EC) is the second gynecological cancer with the highest global incidence. Among many associated risk factors, metabolic syndrome (MetS) is an important and preventable one. It comprises a group of conditions that often occur together: central adiposity, hyperglycemia, arterial hypertension, and atherogenic dyslipidemia. This review aimed to describe the epidemiological and biological relationship between MetS and EC, focusing on the role of lifestyle in prevention. A literature search was carried out in the PubMed database. 4824 publications were screened, and 123 were included for this review. The association between MetS and EC has been described. Chronic adipose tissue inflammation and insulin resistance are involved in the development of obesity, particularly visceral adiposity. These changes promote the ideal environment for the development of EC. Strategies based on lifestyle modifications may be effective for the prevention of MetS and consequently EC. Some of these modifications include adopting a diet rich in fruits, vegetables, whole grains, and legumes, depending to the accessibility of these foods for each region. Avoiding ultra-processed foods and increasing daily physical activity were also some suggested modifications. We propose that women be screened for MetS to establish early treatment and to possibly prevent EC. Clinical trials designed to prove the effect of lifestyle modifications on the prevention of EC are needed.

Abstract
Background Ovarian cancer is the most aggressive gynecological malignancy. Transcriptional regulators impact the tumor phenotype and, consequently, clinical progression and response to therapy. PHD finger protein 20-like protein 1 (PHF20L1) is a transcriptional regulator with several isoforms, and studies on its role in ovarian cancer are limited. We previously reported that PHF20L1 is expressed as a fucosylated protein in SKOV-3 cells stimulated with ascites from patients with ovarian cancer. Methods We decided to analyze the expression of PHF20L1 in ovarian cancer tissues, determine whether a correlation exists between PHF20L1 expression and patient clinical data, and analyze whether ascites can modulate the different isoforms of this protein. Ovarian cancer biopsies from 29 different patients were analyzed by immunohistochemistry, and the expression of the isoforms in ovarian cancer cells with or without exposure to the tumor microenvironment, i.e., the ascitic fluid, was determined by western blotting assays. Results Immunohistochemical results suggest that PHF20L1 exhibits increased expression in sections of tumor tissues from patients with ovarian cancer and that higher PHF20L1 expression correlates with shorter progression-free survival and shorter overall survival. Furthermore, western blotting assays determined that protein isoforms are differentially regulated in SKOV-3 cells in response to stimulation with ascites from patients with epithelial ovarian cancer. Conclusion The results suggest that PHF20L1 could play a relevant role in ovarian cancer given that higher PHF20L1 protein expression is associated with lower overall patient survival.

Abstract
Vasculogenic mimicry is a cellular mechanism in which tumor cells grow and align forming complex three-dimensional (3D) channel-like structures in a hypoxic microenvironment. This phenomenon represents a novel oxygen, nutrient, and blood supply, in a similar way as occurs in classic angiogenesis. Vasculogenic mimicry has been described in numerous clinical tumors including breast, prostate, lung, and ovarian cancers where it is associated with poor prognosis; thus, it is considered as a hallmark of highly aggressive and metastatic tumors. Here, we describe a simple method to model the in vitro formation of three-dimensional cellular networks over Matrigel in SKOV3 ovarian cancer cells representing the early stages of vasculogenic mimicry.

Abstract
Ovarian cancer is the third most frequent gynaecological malignancy worldwide and in Mexico, with a high mortality rate, due to that in many cases its diagnosis is made in advanced stages. Prognosis is important for determining the subtype and the degree of evolution. During lasts years, the management of ovarian cancer has undergone an important evolution with the incorporation of new therapeutic options, which in turn represent an increase in the survival of these patients. We present recommendations for the management of ovarian cancer developed by an expert panel Mexican based on available evidence so far and the characteristics of health care in the country.

Abstract
Endometrial cancer represents the most frequent neoplasia from the corpus uteri, and comprises the 14th leading cause of death in women worldwide. Risk factors that contribute to the disease include early menarche, late menopause, nulliparity, and menopausal hormone use, as well as hypertension and obesity comorbidities. The clinical effectiveness of chemotherapy is variable, suggesting that novel molecular targeted therapies against specific cellular processes associated with the maintenance of cancer cell survival and therapy resistance urged to ameliorate the rates of success in endometrial cancer treatment. In the course of tumor growth, cancer cells must adapt to decreased oxygen availability in the microenvironment by upregulation of hypoxia-inducible factors, which orchestrate the activation of a transcriptional program leading to cell survival. During this adaptative process, the hypoxic cancer cells may acquire invasive and metastatic properties as well as increased cell proliferation and resistance to chemotherapy, enhanced angiogenesis, vasculogenic mimicry, and maintenance of cancer cell stemness, which contribute to more aggressive cancer phenotypes. Several studies have shown that hypoxia-inducible factor 1 alpha (HIF-1α) protein is aberrantly overexpressed in many solid tumors from breast, prostate, ovarian, bladder, colon, brain, and pancreas. Thus, it has been considered an important therapeutic target. Here, we reviewed the current knowledge of the relevant roles of cellular hypoxia mechanisms and HIF-1α functions in diverse processes associated with endometrial cancer progression. In addition, we also summarize the role of microRNAs in the posttranscriptional regulation of protein-encoding genes involved in the hypoxia response in endometrial cancer. Finally, we pointed out the need for urgent targeted therapies to impair the cellular processes activated by hypoxia in the tumor microenvironment.

Abstract
BACKGROUND Platinum-based neoadjuvant chemotherapy followed by delayed primary surgery (DPS) is an established strategy for women with newly diagnosed, advanced-stage epithelial ovarian cancer. Although this therapeutic approach has been validated in randomised, phase 3 trials, evaluation of response to neoadjuvant chemotherapy using Response Evaluation Criteria in Solid Tumors, version 1.1 (RECIST), and cancer antigen 125 (CA125) has not been reported. We describe RECIST and Gynecologic Cancer InterGroup (GCIG) CA125 responses in patients receiving platinum-based neoadjuvant chemotherapy followed by DPS in the ICON8 trial. METHODS ICON8 was an international, multicentre, randomised, phase 3 trial done across 117 hospitals in the UK, Australia, New Zealand, Mexico, South Korea, and Ireland. The trial included women aged 18 years or older with an Eastern Cooperative Oncology Group performance status of 0-2, life expectancy of more than 12 weeks, and newly diagnosed International Federation of Gynecology and Obstetrics (FIGO; 1988) stage IC-IIA high-grade serous, clear cell, or any poorly differentiated or grade 3 histological subtype, or any FIGO (1988) stage IIB-IV epithelial cancer of the ovary, fallopian tube, or primary peritoneum. Patients were randomly assigned (1:1:1) to receive intravenous carboplatin (area under the curve [AUC]5 or AUC6) and intravenous paclitaxel (175 mg/m2 by body surface area) on day 1 of every 21-day cycle (control group; group 1); intravenous carboplatin (AUC5 or AUC6) on day 1 and intravenous dose-fractionated paclitaxel (80 mg/m2 by body surface area) on days 1, 8, and 15 of every 21-day cycle (group 2); or intravenous dose-fractionated carboplatin (AUC2) and intravenous dose-fractionated paclitaxel (80 mg/m2 by body surface area) on days 1, 8, and 15 of every 21-day cycle (group 3). The maximum number of cycles of chemotherapy permitted was six. Randomisation was done with a minimisation method, and patients were stratified according to GCIG group, disease stage, and timing and outcome of cytoreductive surgery. Patients and clinicians were not masked to group allocation. The scheduling of surgery and use of neoadjuvant chemotherapy were determined by local multidisciplinary case review. In this post-hoc exploratory analysis of ICON8, progression-free survival was analysed using the landmark method and defined as the time interval between the date of pre-surgical planning radiological tumour assessment to the date of investigator-assessed clinical or radiological progression or death, whichever occurred first. This definition is different from the intention-to-treat primary progression-free survival analysis of ICON8, which defined progression-free survival as the time from randomisation to the date of first clinical or radiological progression or death, whichever occurred first. We also compared the extent of surgical cytoreduction with RECIST and GCIG CA125 responses. This post-hoc exploratory analysis includes only women recruited to ICON8 who were planned for neoadjuvant chemotherapy followed by DPS and had RECIST and/or GCIG CA125-evaluable disease. ICON8 is closed for enrolment and follow-up, and registered with ClinicalTrials.gov, NCT01654146. FINDINGS Between June 6, 2011, and Nov 28, 2014, 1566 women were enrolled in ICON8, of whom 779 (50%) were planned for neoadjuvant chemotherapy followed by DPS. Median follow-up was 29·5 months (IQR 15·6-54·3) for the neoadjuvant chemotherapy followed by DPS population. Of 564 women who had RECIST-evaluable disease at trial entry, 348 (62%) had a complete or partial response. Of 727 women who were evaluable by GCIG CA125 criteria at the time of diagnosis, 610 (84%) had a CA125 response. Median progression-free survival was 14·4 months (95% CI 9·2-28·0; 297 events) for patients with a RECIST complete or partial response and 13·3 months (8·1-20·1; 171 events) for those with RECIST stable disease. Median progression-free survival for women with a GCIG CA125 response was 13·8 months (95% CI 8·8-23·4; 544 events) and 9·7 months (5·8-14·5; 111 events) for those without a GCIG CA125 response. Complete cytoreduction (R0) was achieved in 187 (56%) of 335 women with a RECIST complete or partial response and 73 (42%) of 172 women with RECIST stable disease. Complete cytoreduction was achieved in 290 (50%) of 576 women with a GCIG CA125 response and 30 (30%) of 101 women without a GCIG CA125 response. INTERPRETATION The RECIST-defined radiological response rate was lower than that frequently quoted to patients in the clinic. RECIST and GCIG CA125 responses to neoadjuvant chemotherapy for epithelial ovarian cancer should not be used as individual predictive markers to stratify patients who are likely to benefit from DPS, but instead used in conjunction with the patient's clinical capacity to undergo cytoreductive surgery. A patient should not be denied surgery based solely on the lack of a RECIST or GCIG CA125 response.

Abstract
Ovarian cancer is the most lethal gynecologic malignancy. The long-established primary treatment for ovarian cancer consisted of surgical cytoreduction followed by platinum-based chemotherapy. Unfortunately, this therapeutic approach is related to a high frequency of early relapses. Further chemotherapy is necessary for recurrent disease, but very few patients can be cured. Poly (ADP-ribose) polymerase (PARP) is a family of proteins involved in various DNA repair activities. PARP inhibition leads to synthetic lethality in BRCA mutated or homologous recombination deficient tumors. The development of PARP inhibitors has changed the way ovarian cancer patients are treated. Olaparib, niraparib and rucaparib are orally active and have demonstrated efficacy for both maintenance and treatment settings. These three drugs have gained regulatory approval for different clinical circumstances. They have an acceptable toxicity profile and are generally well tolerated. Common class toxicities include hematologic effects, gastrointestinal effects and fatigue. Moreover, new treatment strategies that combine PARP inhibitors with other drugs, such as angiogenic agents, are being explored. The purpose of this review is to describe the evidence that define the current clinical role of PARP inhibitors in ovarian cancer. The implementation of rationally designed new clinical trials will be crucial to facilitate the best selection of patients and to continue improving clinical outcomes.

Abstract
BACKGROUND Health-related quality of life (HRQL) is an important outcome measure in Oncology. AIM OF THE STUDY To validate the Mexican-Spanish version of the QLQ-OV28 questionnaire to assess HRQL in women with ovarian cancer (OC). METHODS The QLQ-C30 and QLQ-OV28 instruments were applied to women with OC attending a cancer center in Mexico. The usual psychometric analyses were performed; the Spearman's method was used for correlation analysis, reliability analysis with the Cronbach's alpha, known-group comparisons with the Kruskal-Wallis test, responsiveness was tested employing repeated measures ANOVA, and the association of scale scores and overall survival (OS) were analyzed with the Kaplan-Meier method and Cox's model. RESULTS Two hundred fifty-two women with OC were included in this cohort. The instruments were well accepted and compliance rates were high; patients responded both instruments in <30 min. The QLQ-OV28 internal consistency tests demonstrated good convergent (Correlation coefficients [CC] 0.154‒0.694) and divergent validity (CC 0.003‒0.69). Cronbach's α coefficients of six of eight scales of the QLQ-OV28 instruments were >0.7 (range, 0.567‒0.857). Scales QLQ-OV28 instruments distinguished among clinically distinct groups of patients, particularly after basal serum albumin and basal Ca‒125 levels. The evaluation of responsiveness demonstrated that two scales of the QLQ-OV28 were sensitive to change over time during induction chemotherapy. Six scales of the QLQ-OV28 were associated with OS. CONCLUSIONS The Mexican-Spanish version of the QLQ-OV28 questionnaire is reliable and valid for the assessment of HRQL in patients with OC and can be broadly used in clinical trials.

Abstract
Ovarian cancer (OC) is an important cause of gynecologic cancer-related deaths. In Mexico, around 4700 new cases of OC are diagnosed per year and it represents the second cause of gynecological cancer mortality with more than 2700 deaths. Germline mutations in BRCA1/2 genes are present in 13–18% of OC cases. Few studies have evaluated the presence of mutations in BRCA genes in a population of OC Mexican patients and their relationship with clinical response and survival rates. A total of 179 OC patients were studied by molecular testing for BRCA1/2 through next-generation sequencing and multiplex ligation-dependent probe amplification. Recurrence-free survival (RFS) was estimated by the Kaplan–Meier method. BRCA mutation was detected in 33% of patients. A percentage of 66.1% were BRCA1 mutated and 33.9% were BRCA2 mutated. BRCA1 mutation carriers had a worst RFS compared with BRCA2 mutation carriers (37.6 [29–46.2] vs 72.7 [38.4–107.2]; P = 0.030). The most common mutation for BRCA1 was ex9-12del (28.2%) (Mexican founder mutation). The Mexican founder mutation had a better RFS than other BRCA1 mutations (86.1 [37.2–135.1] vs 34.5 [20.7–48.2]; P = 0.033). The presence of BRCA2 mutations in the ovarian cancer cluster region (OCCR) had a significantly better RFS than mutations in breast cancer cluster regions (BCCR) and not-related risk region (NRR) (NR vs 72.8 [39–106.6] vs 25.8 [8.3–43.2]; P = 0.013). These results demonstrate that the prevalence of BRCA1/2 positive patients in OC Mexican patients are the highest reported. Patients with mutations in BRCA2 have a better prognosis than those mutated in BRCA1. The Mexican founder mutation has an important role in clinical outcomes. These results highlight the importance to test all the HGSP (high-grade serous papillary) OC patients with or without cancer family history (CFH) in Mexican population.

Abstract
Introduction More than the twenty percent of ovarian cancers are hereditary, and most have BRCA mutations. The 30% of Mexican patients with the BRCA1 mutation have the BRCA1 gene exon 9-12del deletion founder mutation (BRCA1 ex9-12del). BRCA-mutated tumors are more sensitive to PARP inhibitors such as olaparib. Objective To show the clinical experience on the use of olaparib at Instituto Nacional de Cancerología in Mexico. Method Ovarian cancer patients treated with olaparib from November 2016 to December 2018 were studied, and their characteristics, clinical response, progression-free survival (PFS) and toxicities were described. Results Nineteen patients were assessed, with BRCA1 mutation being found in 78.9%, out of which 21.1% were carriers of the ex9-12del founder mutation. The median of PFS was 12 months; for patients treated on second and third line it was > 15 months, and for those treated with a fourth and subsequent line it was 8.3 months. Patients with the founder mutation had better results. Toxicities were like those reported in previous studies. Conclusions Olaparib offers greater PFS benefit as maintenance therapy after a first and second relapse. Patients with founder mutation have had sustained PFS.

Abstract
Endometrial cancer is the fourth most frequent neoplasia for women worldwide, and over the past two decades it incidence has increased. The most common histological type of endometrial cancer is endometrioid adenocarcinoma, also known as type 1 endometrial cancer. Endometrioid endometrial cancer is associated with diverse epidemiological risk factors including estrogen use, obesity, diabetes, cigarette smoking, null parity, early menarche, and late menopause. Clinical effectiveness of chemotherapy is variable, indicating that novel molecular therapies against specific cellular processes associated to cell survival and resistance to therapy, such as autophagy, urged to ameliorate the rates of success in endometrial cancer treatment. Autophagy (also known as macroautophagy) is a specialized mechanism that maintains cell homeostasis which is activated in response to cellular stressors including nutrients deprivation, amino acids starvation, hypoxia, and metabolic stress to prolong cell survival via lysosomal degradation of cytoplasmic macromolecules and organelles. However, in human cancer cells, autophagy has a controversial function due to its dual role as self-protective or apoptotic. Conventional antitumor therapies including hormones, chemotherapy and ionizing radiation, may activate autophagy as a pro-survival tumor response contributing to treatment resistance. Intriguingly, if autophagy continues above reversibility of cell viability, autophagy can result in apoptosis of tumor cells. Here, we have reviewed the mechanisms of autophagy described in endometrial cancers, including the role of PI3K/AKT/mTOR, AMPK-mTOR, and p53 signaling pathways that trigger or inhibit the process and thus representing potential molecular targets in therapeutic clinical approaches. In addition, we discussed the recent findings indicating that autophagy can be modulated using repurposing drugs which may leads to faster experimentation and validation, as well as more easy access of the medications to patients. Finally, the promising role of dietary compounds and microRNAs in autophagy modulation is also discussed. In conclusion, although the research about autophagy is scarce but ongoing in endometrial cancer, the actual findings highlight the promising usefulness of novel molecules for directing targeted therapies.

Abstract
The deletion of exons 9 to 12 of BRCA1 (9-12 del BRCA1) is considered a founder mutation in the Mexican population. We evaluate the usefulness of the target detection of 9-12 del BRCA1 as the first molecular diagnostic strategy in patients with Hereditary Breast and Ovarian Cancer (HBOC). We performed the genetic assessment of 637 patients with suspected HBOC. The region corresponding to the breakpoints for the 9-12 del BRCA1 was amplified by polymerase chain reaction (PCR). An analysis of the clinical data of the carriers and non-carriers was done, searching for characteristics that correlated with the deletion. The 9-12 del BRCA1 was detected in 5% of patients with suspected HBOC (30/637). In patients diagnosed with ovarian cancer, 13 of 30 were 9-12 del BRCA1 carriers, which represents 43%. We found a significant association between the 9-12 del BRCA1 carriers with triple negative breast cancer and high-grade papillary serous ovarian cancer. We concluded that the detection of the 9-12 del BRCA1 is useful as a first molecular diagnostic strategy in the Mexican population. In particular, it shortens the gap in genetic assessment in patients with triple negative breast cancer and ovarian cancer.

Abstract
BACKGROUND Right-colon cancer (RCC) presents differences with Left-colon cancer (LCC) in terms of Overall survival (OS), but certain reports provide conflicting findings. Our objective is to define differences regarding prognostic factors in RCC and LCC by multivariate analysis. METHODS Retrospective cohort including patients treated from 1992-2016. The Kaplan-Meier and Cox models were used to define prognostic factors. RESULTS 871 patients had RCC and 748 LCC; mean age was 58.1. Location was associated with socioeconomic status, body mass, blood hemoglobin, serum albumin, lymphocyte count and Prognostic nutritional index (PNI). Distribution of TNM stages was similar between groups, as well as gender, age, surgical morbidity/mortality; 72.3% of RCC and 83.2% of LCC were well/moderately differentiated (p <0.0001). Mean surgical lymph-node retrieval was 19.3 (SD14.6) for RCC and 15.7 (SD13.1) for LCC (p <0.0001). Median OS was 5.2 (95% CI 3.9-6.5) for RCC, and 3.2 years (95% CI 2.1-4.4) for LCC (p = 0.426). OS was different between RCC and LCC by stratified analyses within PNI, TNM, differentiation and R classification. RCC presents different OS in stages IIIC, and IVB than LCC. CONCLUSION Differences between RCC and LCC were mainly by immunonutritional variables. Differences in OS were found after stratified analysis of PNI, TNM stages, differentiation degree, and R classification. Location of the neoplasm in the colon should be considered in the design of clinical trials in patients with colon cancer.

Abstract
Vasculogenic mimicry (VM) is a novel cancer hallmark in which malignant cells develop matrix-associated 3D tubular networks with a lumen under hypoxia to supply nutrients needed for tumor growth. Recent studies showed that microRNAs (miRNAs) may have a role in VM regulation. In this study, we examined the relevance of hypoxia-regulated miRNAs (hypoxamiRs) in the early stages of VM formation. Data showed that after 48 h hypoxia and 12 h incubation on matrigel SKOV3 ovarian cancer cells undergo the formation of matrix-associated intercellular connections referred hereafter as 3D channels-like structures, which arose previous to the apparition of canonical tubular structures representative of VM. Comprehensive profiling of 754 mature miRNAs at the onset of hypoxia-induced 3D channels-like structures showed that 11 hypoxamiRs were modulated (FC>1.5; p < 0.05) in SKOV3 cells (9 downregulated and 2 upregulated). Bioinformatic analysis of the set of regulated miRNAs showed that they might impact cellular pathways related with tumorigenesis. Moreover, overall survival analysis in a cohort of ovarian cancer patients (n = 485) indicated that low miR-765, miR-193b, miR-148a and high miR-138 levels were associated with worst patients outcome. In particular, miR-765 was severely downregulated after hypoxia (FC < 32.02; p < 0.05), and predicted to target a number of protein-encoding genes involved in angiogenesis and VM. Functional assays showed that ectopic restoration of miR-765 in SKOV3 cells resulted in a significant inhibition of hypoxia-induced 3D channels-like formation that was associated with a reduced number of branch points and patterned tubular-like structures. Mechanistic studies confirmed that miR-765 decreased the levels of VEGFA, AKT1 and SRC-α transducers and exerted a negative regulation of VEGFA by specific binding to its 3‘UTR. Finally, overall survival analysis of a cohort of ovarian cancer patients (n = 1435) indicates that high levels of VEGFA, AKT1 and SRC-α and low miR-765 expression were associated with worst patients outcome. In conclusion, here we reported a novel hypoxamiRs signature which constitutes a molecular guide for further clinical and functional studies on the early stages of VM. Our data also suggested that miR-765 coordinates the formation of 3D channels-like structures through modulation of VEGFA/AKT1/SRC-α axis in SKOV3 ovarian cancer cells.

Abstract
BACKGROUND The TNM classification does not completely reflect the prognosis of patients with colorectal cancer (CRC). Several clinical factors have been used to increase its prognostic value, but factors pertaining to the patient's immunonutritional status have not usually been addressed. The aim of this study is to evaluate the role of Prognostic nutritional index (PNI) and other well-known prognostic factors by multivariate analysis in a cohort of patients with CRC. METHODS This is a retrospective cohort study of consecutive patients with CRC managed in a cancer center between January 1992 and December 2016. Cox's model was used to define the association of the PNI and other factors with Overall survival (OS). RESULTS A total of 3301 patients were included: 47.7% were female and 52.3% were male, with a mean age of 58.7 years. By bivariate analysis, PNI was strongly associated with OS (Risk ratio [RR] 0.968, 95% Confidence interval [CI] 0.962-0.974; P < 0.001). On multivariate analysis, PNI was an independent explanatory variable (as continuous variable and as categorized variable; RR 0.732, 95% CI 0.611-0.878; RR 0.656, 95% CI 0.529-0.813 and RR 0.646, 95% CI 0.521-0.802, for quintiles 2, 3, and 4-5, respectively); a biological gradient effect was demonstrated. The final prognostic model included PNI, location of the neoplasia in the colorectum, basal hemoglobin, lymphocyte count, neutrophil/lymphocyte ratio, platelet/lymphocyte ratio, TNM stage, differentiation degree, R classification, and postoperative complications. CONCLUSIONS PNI is a significant and independent prognostic factor in patients with CRC. Its prognostic value adds precision to the TNM staging system including specific subgroups of patients with CRC; it should be evaluated in prospective clinical studies.

Abstract
Epigenetic mechanisms control gene expression during normal development and their aberrant regulation may lead to human diseases including cancer. Natural phytochemicals can largely modulate mammalian epigenome through regulation of mechanisms and proteins responsible for chromatin remodeling. Phytochemicals are mainly contained in fruits, seeds, and vegetables as well as in foods supplements. These compounds act as powerful cellular antioxidants and anti-carcinogens agents. Several dietary compounds such as catechins, curcumin, genistein, quercetin and resveratrol, among others, exhibit potent anti-tumor activities through the reversion of epigenetic alterations associated to oncogenes activation and inactivation of tumor suppressor genes. In this review, we summarized the actual knowledge about the role of dietary phytochemicals in the restoration of aberrant epigenetic alterations found in cancer cells with a particular focus on DNA methylation and histone modifications. Furthermore, we discussed the mechanisms by which these natural compounds modulate gene expression at epigenetic level and described their molecular targets in diverse types of cancer. Modulation of epigenetic activities by phytochemicals will allow the discovery of novel biomarkers for cancer prevention, and highlights its potential as an alternative therapeutic approach in cancer.

Abstract
Radiotherapy is a fundamental part of the treatment of pelvic neoplasms. Up to 90% of patients develop gastrointestinal symptoms as a result of acute injury to the small and large intestine, particularly in the mucosa. Radiotherapy leads to atrophy of the intestinal epithelium, acute crypt inflammation, inflammatory infiltration of the epithelium, malabsorption of lactose, and biliary salts as well as alterations in pancreatic enzymes and biliary salts, resulting in the malabsorption syndrome and dysbiosis. The most commonly reported symptoms of pelvic radiation disease include changes in bowel habits (94%), decreased fecal consistency (80%), frequency of bowel movements (74%), bowel urgency (39%), and fecal incontinence (37%). Although nutritional interventions with dietary modifications have been reported to prevent and treat gastrointestinal symptoms, the evidence remains inconclusive.

Abstract
Angiogenesis is an important hallmark of cancer serving a key role in tumor growth and metastasis. Therefore, tumor angiogenesis has become an attractive target for development of novel drug therapies. An increased amount of anti‑angiogenic compounds is currently in preclinical and clinical development for personalized therapies. However, resistance to current angiogenesis inhibitors is emerging, indicating that there is a need to identify novel anti‑angiogenic agents. In the last decade, the field of microRNA biology has exploded revealing unsuspected functions in tumor angiogenesis. These small non‑coding RNAs, which have been dubbed as angiomiRs, may target regulatory molecules driving angiogenesis, such as cytokines, metalloproteinases and growth factors, including vascular endothelial growth factor, platelet‑derived growth factor, fibroblast growth factor, epidermal growth factor, hypoxia inducible factor‑1, as well as mitogen‑activated protein kinase, phosphoinositide 3‑kinase and transforming growth factor signaling pathways. The present review discusses the current progress towards understanding the functions of miRNAs in tumor angiogenesis regulation in diverse types of human cancer. Furthermore, the potential clinical application of angiomiRs towards anti‑angiogenic tumor therapy was explored.

Abstract
Cervical cancer is the fourth most common cancer in women with 85% of the mortality burden occurring in less-developed regions of the world. The Cervix Cancer Research Network (CCRN) was founded by the Gynecologic Cancer InterGroup (GCIG) with a mission to improve outcomes in cervix cancer by increasing access to high-quality clinical trials worldwide, with particular attention to less-developed, underrepresented sites. The CCRN held its second international educational symposium in Mexico City with ninety participants from fifteen Latin America countries in January 2017. The purpose of this symposium was to advance knowledge in cervix cancer therapy, promote recruitment to CCRN clinical trials, and to identify relevant future CCRN clinical trial concepts that could improve global care standards for women with cervical cancer. Cervix cancer is the fourth most common cancer in women worldwide with up to an 18-fold disparity in mortality rates. The Cervix Cancer Research Network (CCRN) aims to increase access to clinical trials in order to improve outcomes for women. The 2nd CCRN international symposium was held in Mexico City including 90 participants from 15 Latin American countries. CCRN clinical trials were discussed, including new trials proposed of hypofractionation and HPV targeted therapy.

Abstract
Background Epithelial ovarian cancer is the second most lethal gynecological cancer worldwide. Ascites can be found in all clinical stages, however in advanced disease stages IIIC and IV it is more frequent and could be massive, associated with worse prognosis. Due to the above, it was our interest to understanding how the ascites of ovarian cancer patients induces the mechanisms by which the cells present in it acquire a more aggressive phenotype and to know new proteins associated to this process. Methods A proteomic analysis of SKOV-3 cells treated with five different EOC ascites was performed by two-dimensional electrophoresis coupled to MALDI-TOF. The level of expression of the proteins of interest was validated by RT-PCR because several of these proteins have only been reported at the messenger level. Results Among the proteins identified that increased their expression in ascites-treated SKOV-3 cells, were Ran GTPase, ZNF268, and Synaptotagmin like-3. On the other hand, proteins that were negatively regulated by ascites were HLA-I, HSPB1, ARF1, Synaptotagmin 1, and hnRNPH1, among others. Furthermore, an interactome for every one of these proteins was done in order to identify biological processes, molecular actions, and cellular components in which they may participate. Conclusions Identified proteins participate in cellular processes highly relevant to the aggressive phenotype such as nuclear transport, regulation of gene expression, vesicular trafficking, evasion of the immune response, invasion, metastasis, and in resistance to chemotherapy. These proteins may represent a source of information which has the potential to be evaluated for the design of therapies directed against these malignant cells that reside on ovarian cancer ascites.

Abstract
The epithelial ovarian cancer (EOC) has been underdiagnosed because it does not have a specific clinical presentation, and the signs and symptoms are similar to the irritable bowel syndrome and pelvic inflammatory disease. EOC is less common than breast and cervical cancer, but it is more lethal. On the whole, EOC has an early dissemination to peritoneal cavity, which delays a timely diagnosis and increases the rate of advanced diagnosed disease. The diagnosis usually surprises the women and the primary care physician. Therefore, it is necessary to count on prevention and early diagnosis programs. EOC has 80% response to surgical treatment, but nearly 70% of the patients may relapse in five years. The objectives of this document are presenting a summary of the EOC epidemiology and comment about advancements in prevention, diagnosis, and treatment of this cancer. That will raise awareness about the importance of this disease.

Abstract
The aim of the present study was to define the prognostic role of baseline serum albumin (BSA) in colorectal cancer (CRC) across tumor-node-metastasis (TNM) stages and other well defined prognostic factors. Many prognostic models in medicine employ BSA to define or refine treatments in very specific settings; in CRC, BSA has been found to be a prognostic factor as well. A retrospective cohort study of consecutive patients with CRC demonstrated by biopsy, who attended a cancer center during a 7-year period. Multivariate analysis was utilized to define prognostic factors associated with overall survival (OS) employing the Cox model. In this retrospective cohort study, 1465 patients were included; 46.6% were females and 53.4% males (mean age, 59.1 years). Mean BSA was inversely correlated with TNM stages. By multivariate analysis, it was an independent explanatory variable. TNM stages, "R" classification, age, lymphocyte count, neutrophil/platelet ratio, neutrophil/lymphocyte ratio, platelet/lymphocyte ratio, postoperative morbidity, and BSA were independently associated with OS. Morbidities, surgery type, chemotherapy, and radiotherapy were considered confounders after adjusting by TNM stages. BSA is a significant and independent prognostic factor in patients with CRC, and its effect is maintained across TNM strata and other well known clinical prognostic factors. It can be easily used in prognostic models and should be employed to stratify prognosis in therapeutic randomized clinical trials.

Abstract
Haptoglobin (Hp) is an acute-phase protein that is produced by the liver to capture the iron that is present in the blood circulation, thus avoiding its accumulation in the blood. Moreover, Hp has been detected in a wide variety of tissues, in which it performs various functions. In addition, this protein is considered a potential biomarker in many diseases, such as cancer, including ovarian carcinoma; however, its participation in the cancerous processes has not yet been determined. The objective of this work was to demonstrate the expression of Hp and its receptor CCR2 in the ovarian cancer cells and its possible involvement in the process of cell migration through changes in the rearrangement of the actin cytoskeleton using western blot and wound-healing assays and confirming by confocal microscopy. Ovarian cancer cells express both Hp and its receptor CCR2 but only after exposure to ascitic fluid, inducing moderated cell migration. However, when the cells are exposed to exogenous Hp, the expression of CCR2 is induced together with drastic changes in the actin cytoskeleton rearrangement. At the same time, Hp induced cell migration in a much more efficient manner than did ascitic fluid. These effects were blocked when the CCR2 synthetic antagonist RS102895 was used to pretreat the cells. These results suggest that Hp-induced changes in the cell morphology, actin cytoskeleton structure, and migration ability of tumor cells, is possibly “preparing” these cells for the potential induction of the metastatic phenotype.

Abstract
Background Ovarian cancer is the most lethal gynecologic disease due to delayed diagnosis, and ascites production is a characteristic of patients in advanced stages. The aim of this study was to perform the proteomic analysis of ascitic fluids of Mexican patients with ovarian carcinoma, in order to detect proteins with a differential expression pattern in the continuing search to identify biomarkers for this disease. Methods Samples were collected from 50 patients from the Instituto Nacional de Cancerología of México under informed consent and with approval of the bioethics and scientific committees. After elimination of abundant proteins (Albumin/IgGs) samples were processed for 2D electrophoresis and further protein identification by Mass Spectrometry (MALDI-TOF). Molecules of interest were followed by western blot and lectin binding assays, and their tissue location by histo-immunofluorescence and confocal analysis. Results and discussion An area with a differential expression pattern among samples was located in the 2D gels. Identified proteins were 6 alpha 1 isoforms and 1 alpha 2 isoform of Haptoglobin, and 2 isoforms of Transthyretin. While Transthyretin isoforms were constitutively expressed in all samples, clear differences in the expression pattern of Haptoglobin alpha isoforms were found. Moreover, increased levels of fucosylation of Haptoglobin alpha isoforms analyzed in 40 samples by Aleuria aurantia lectin binding by 1D overlay assay showed a positive correlation with advanced stages of the disease. Tissue detection of Haptoglobin and its fucosylated form, by histo-immunofluorescence in biopsies of ovarian cancer, also showed a correlation with ovarian cancer progression. Moreover, results show that fucosylated Haptoglobin is produced by tumor cells. Conclusions Increased numbers of highly fucosylated Haptoglobin alpha isoforms in ascitic fluids and the presence of fucosylated Haptoglobin in tumor tissues of ovarian cancer Mexican patients associated with advanced stages of the disease, reinforce the potential of fucosylated Haptoglobin alpha isoforms to be characterized as biomarkers for disease progression.

Abstract
Mexican specialists in oncology, oncologic surgery, thoracic surgery, pneumology, pathology, molecular biology, anesthesiology, algology, psychology, nutrition, and rehabilitation (all of them experts in lung cancer treatment) in order to develop the National Consensus on Lung Cancer. The consensus has been developed as an answer to the need of updated Mexican guidelines for the optimal treatment of the disease, as well as to the requirements that such guidelines be established by multidisciplinary panel, depicting the current attention given to cancer lung cases in Mexico. Thus, this paper analyses the epidemiological review, screening, diagnosis, staging, pathology, translational medicine, and the suitable therapies for early, locally advanced, and metastatic disease in the first, second, and third lines of management, as well as rehabilitation and palliative measures.

Abstract
INTRODUCTION Ovarian cancer (OC) is the third most common gynecologic malignancy worldwide. Most of cases it is of epithelial origin. At the present time there is not a standardized screening method, which makes difficult the early diagnosis. The 5-year survival is 90% for early stages, however most cases present at advanced stages, which have a 5-year survival of only 5-20%. GICOM collaborative group, under the auspice of different institutions, have made the following consensus in order to make recommendations for the diagnosis and management regarding to this neoplasia. 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 two days in which a debate was held. These statements are the conclusions reached by agreement of the participant members. RESULTS No screening method is recommended at the time for the detection of early lesions of ovarian cancer in general population. Staging is surgical, according to FIGO. In regards to the pre-surgery evaluation of the patient, it is recommended to perform chest radiography and CT scan of abdomen and pelvis with IV contrast. According to the histopathology of the tumor, in order to consider it as borderline, the minimum percentage of proliferative component must be 10% of tumor's surface. The recommended standardized treatment includes primary surgery for diagnosis, staging and cytoreduction, followed by adjuvant chemotherapy Surgery must be performed by an Oncologist Gynecologist or an Oncologist Surgeon because inadequate surgery performed by another specialist has been reported in 75% of cases. In regards to surgery it is recommended to perform total omentectomy since subclinic metastasis have been documented in 10-30% of all cases, and systematic limphadenectomy, necessary to be able to obtain an adequate surgical staging. Fertility-sparing surgery will be performed in certain cases, the procedure should include a detailed inspection of the contralateral ovary and also negative for malignancy omentum and ovary biopsy. Until now, laparoscopy for diagnostic-staging surgery is not well known as a recommended method. The recommended chemotherapy is based on platin and taxanes for 6 cycles, except in Stage IA, IB and grade 1, which have a good prognosis. In advanced stages, primary cytoreduction is recommended as initial treatment. Minimal invasion surgery is not a recommended procedure for the treatment of advanced ovarian cancer. Radiotherapy can be used to palliate symptoms. Follow up of the patients every 2-4 months for 2 years, every 3-6 months for 3 years and anually after the 5th year is recommended. Evaluation of quality of life of the patient must be done periodically. CONCLUSIONS In the present, there is not a standardized screening method. Diagnosis in early stages means a better survival. Standardized treatment includes primary surgery with the objective to perform an optimal cytoreduction followed by chemotherapy Treatment must be individualized according to each patient. Radiotherapy can be indicated to palliate symptoms.

Abstract
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.

Abstract
BACKGROUND AND OBJECTIVE Indications for gastrectomy in T4 gastric carcinoma (GC) remain controversial. Our aim was to define prognostic factors to select those patients with best chance to benefit from multiorgan resection. MATERIALS AND METHODS A cohort of patients with T4 GC treated in a 19-year period. Surgical morbidity-associated factors were identified by logistic regression analysis. Prognostic factors were defined by Kaplan-Meier and Cox methods. RESULTS Seven hundred eighteen patients were included (gastrectomy performed in 169). Surgical morbidity and mortality were 39% and 10.7%, respectively. Surgical morbidity were associated to extent of gastrectomy, age, serum albumin, and lymphocyte count (P = 0.0001). Presence of metastasis (hazard ratio [HR], 1.68; 95% confidence interval [95% CI], 1.19-2.36), albumin <3 g/dl plus lymphocytes <1,000 cells/mm(3) (HR, 2.9; 95% CI, 1.8-4.6), presence of ascites (HR, 2.1; 95% CI, 1.06-4.2), age >or=50 (HR, 1.37; 95% CI, 1.02-1.8), and unresectable disease (HR, 2.6; 95% CI, 1.7-4.1) defined poor survival (P = 0.00001). CONCLUSION Performing a multiorgan resection must be balanced between chances for long-term survival and surviving a potentially fatal operation. Absence of metastases, serum albumin levels >3 g/dl, and accomplishment of R0 resection select patients with high probability of benefit from multiorgan resection.

Abstract
BACKGROUND Epigenetic aberrations lead to chemotherapy resistance; hence, their reversal by inhibitors of DNA methylation and histone deacetylases may overcome it. PATIENTS AND METHODS Phase II, single-arm study of hydralazine and magnesium valproate added to the same schedule of chemotherapy on which patients were progressing. Schedules comprised cisplatin, carboplatin, paclitaxel, vinorelbine, gemcitabine, pemetrexed, topotecan, doxorubicin, cyclophosphamide, and anastrozole. Patients received hydralazine at 182 mg for rapid, or 83 mg for slow, acetylators, and magnesium valproate at 40 mg/kg, beginning a week before chemotherapy. Response, toxicity, DNA methylation, histone deacetylase activity, plasma valproic acid, and hydralazine levels were evaluated. RESULTS Seventeen patients were evaluable for toxicity and 15 for response. Primary sites included cervix (3), breast (3), lung (1), testis (1), and ovarian (7) carcinomas. A clinical benefit was observed in 12 (80%) patients: four PR, and eight SD. The most significant toxicity was hematologic. Reduction in global DNA methylation, histone deacetylase activity, and promoter demethylation were observed. CONCLUSIONS The clinical benefit noted with the epigenetic agents hydralazine and valproate in this selected patient population progressing to chemotherapy' and re-challenged with the same chemotherapy schedule after initiating hydralazine and valproate' lends support to the epigenetic-driven tumor-cell chemoresistance hypothesis (ClinicalTrials.gov Identifier: NCT00404508).

Abstract
15141 Background: Background: Indications for gastrectomy in T4 gastric carcinoma (GC) remain controversial. Our aim was to develop a method for the selection of patients with T4 GC with best chances to receive a benefit from multiorgan resection. Methods: We analyzed a cohort of patients with T4 GC treated from January 1987 to December 2005. Relevant clinical, pathological and therapeutic variables were recorded. Prognostic factors associated with survival were defined by Kaplan-Meier and Cox’s methods. Factors associated to surgical morbidity were selected by Logistic Regression analysis. Results: 718 patients were included (gastrectomy performed in 169). Presence of metastasis (Hazard ratio=1.68 [HR], 95% confidence interval [CI] 1.19–2.36), albumin <3 g/dL plus lymphocytes <1,000 cells/mm3 (HR=2.9, 95% CI 1.8–4.6), presence of ascites (HR=2.1, 95% CI 1.06–4.2), 50 years old or more (HR=1.37, 95% CI 1.02–1.8) and surgical resection not possible (HR=2.6, 95% CI 1.7–4.1) define patients with the worst survival (model p=0.00001). Including only patients who underwent surgical resection, presence of metastases, extent of gastrectomy, serum albumin level and R1-R2 residual were determinants of poor survival (model p=0.00001). Surgical morbidity and mortality were 39% and 10.7%, respectively. The significant factor associated to surgical morbidity were extent of gastrectomy, age, serum albumin and lymphocyte count (model p=0.0001). Conclusion: The decision to perform a curative gastrectomy in patients with T4 GC must be balanced between the chances of long-term survival and the chances to survive a potentially fatal operation. Abscence of lymph node and distant metastases, adequate blood lymphocyte count and normal serum albumin levels could help to select those patients with high probability to receive benefit from multiorgan resection as long as R0 resection is performed. The role of preoperative chemoradiation or perioperative chemotherapy in T4 GC must be defined. No significant financial relationships to disclose.

Abstract
BACKGROUND Adenocarcinoma of the esophagogastric junction (EGJ) is rapidly increasing in the west. Our aim is to define the prognostic factors and treatment of EGJ carcinoma in Mexico, particularly the location after the Siewert's classification. METHODS A retrospective cohort of patients suffering from EGJ adenocarcinoma treated from 1987 to 2000. The Kaplan-Meier and the Cox's models were used to define prognostic factors. RESULTS Two hundred and thirty-four patients were included, 90 females and 144 males. Surgical resection was possible in 68 cases only (29%). Significant prognostic factors were tumor node metastasis (TNM) stage [stages I-II: risk ratio (RR) is 1; stage III RR is 1.3, 95% confidence interval (CI) 0.75-2.4; stage IV RR, 2.04, 95% CI 1.1-3.7], gender (male RR = 1.47, 95% CI 1.05-2.05), metastatic lymph node ratio (no resection: RR = 1; ratio 0.2-1 RR=0.67, 95% CI 0.39-1.14; ratio 0-0.19 RR = 0.42, 95% CI 0.23-0.76) and seralbumin (3 mg/dL or less RR = 2.05 95% CI 1.3-3.2; 3.1-3.4 mg/dL RR = 1.9 95% CI 1.2-3.03; 3.5-3.8 mg/dL RR = 1.3 95% CI 0.8-1.9; 3.9 mg/dL or more: RR = 1) (model P = 0.0001). CONCLUSIONS EGJ adenocarcinoma is a highly lethal neoplasia and the location after the Siewert' classification is not a prognostic factor. In Mexico, TNM clinical stage, serum albumin, gender, surgical resection and metastatic lymph node ratio are significant prognostic factors. Curative treatment is infrequent but radical resection is associated to longer survival. Consequently, the management must consider quality of life and surgical morbidity.

Abstract
BACKGROUND The definition of prognostic factors in gastric carcinoma (GC) remains controversial. The potential of serum albumin as a prognostic factor for GC is emphasized because the technique to measure it is simple as well as being cheap and widely available. Our aim was to define the prognostic role of serum albumin in GC. METHODS A cohort treated from January 1987 to December 2002 was studied. Relevant clinical, pathological and therapeutic variables were recorded. Kaplan-Meier and Cox's methods were used to define prognostic factors associated with cancer-related survival. RESULTS One thousand and twenty-three patients were included. Serum albumin did impact survival, showing a dose-response effect. This effect was present after adjustment for other prognostic factors, including Tumor-Node-Metastasis (TNM) stage, surgical resection and type of lymphadenectomy. In multivariate analysis, TNM stage [Stage Ia and Ib Hazard Ratio [HR] 1, Stage II HR 1.6 (95% confidence interval [CI], 0.56-4.7), Stage IIIa HR 4.4 (95% CI 1.7-11.3), Stage IIIb HR 5.6 (95% CI 2.6-17.2), Stage IV HR 6.8 (95% CI 2.7-17.5), high albumin HR 1, medium albumin HR 1.2 (95% CI 0.8-1.7), low albumin HR 1.2 (95% CI 0.8-1.8), very low albumin HR 1.8 (95% CI 1.3-2.6), D2 dissection HR 1, D1 dissection HR 1.9 (95% CI 1.3-2.97), and no resection HR 3.7 (95% CI 2.4-5.7)] were the most significant prognostic factors associated to survival (model P = 0.00001). CONCLUSION Pretherapeutic serum albumin level is a significant prognostic factor, which should be evaluated along with other well-defined prognostic factors in decisions concerning therapy for GC.

Abstract
Meigs' syndrome is the association of ovarian fibroma, pleural effusion, and ascites. Meigs' syndrome with marked elevation of CA125 is an unusual clinical condition reported in 27 cases in the literature. The patient was a 46-year-old woman with right pleural effusion, ascites, ovarian tumor, and CA125 level of 1808 U/mL. Tomography revealed ascites and bilobate pelvic tumor of approximately 25 cm. The diagnosis of advanced epithelial ovarian cancer was considered, and the patient was treated with chemotherapy. Three chemotherapy schemes were applied due to the total lack of response in tumor volume; however, CA125 decreased to 90 U/mL. Thus, surgery was performed with resection of 25 cm of the left ovarian tumor, with intact capsule and without implants; the result of histopathologic analysis was fibroma. Postoperative CA125 was 11 U/mL. Patients with elevated CA125 and ascites cytology positive for malignancy must be cautiously treated due to the possibility of false positives, even if the probability is low. Therefore, minimally invasive surgery for biopsy collection must be considered. Although the association between ovarian tumor, pleural effusion, ascites, and marked elevation of CA125 is highly indicative of epithelial ovarian cancer, Meigs' syndrome must be considered in the differential diagnosis.

Abstract
The HER2 oncogene encodes a transmembrane protein partially homologous to epidermal growth factor receptor. This oncogene has been studied mainly in breast cancer where it has prognostic, predictive and therapeutic target value. The expression of HER2 in epithelial ovarian cancer has been less studied. HER2 expression can be determined through IHC, FISH, CISH and ELISA among other tests, with reported positivity frequencies of overexpression varying from 1.8% to 76%. In some studies HER2 overexpression has been associated with advanced stages, poorly differentiated tumors, resistance to chemotherapy and shortened survival. Although trastuzumab is able to produce a low response rate as a single agent in pretreated ovarian cancer patients with overexpression of HER2, its usefulness is limited due to the low frequency of strong expression. To date there is not enough bases for assessment and HER2-based therapies in epithelial ovarian cancer.

Abstract
SUMMARY BACKGROUND Secretory carcinoma (SC) of the breast is a rare and indolent tumor. Although originally described in children, it is now known to occur in adults of both sexes. Recently, the tumor was associated with the ETV6-NTRK3 gene translocation. CASE PRESENTATION A 52-year-old male was diagnosed with secretory breast carcinoma and underwent a modified radical mastectomy. At 18 months the tumor recurred at the chest wall and the patient developed lung metastases. He was treated concurrently with radiation and chemotherapy without response. His tumor showed the ETV6-NTRK3 translocation as demonstrated by fluorescent in situ hybridization (FISH). CONCLUSION SC is a rare slow-growing tumor best treated surgically. There are insufficient data to support the use of adjuvant radiation or chemotherapy. Its association with the ETV6-NTRK3 fusion gene gives some clues for the better understanding of this neoplasm and eventually, the development of specific therapies.
