MOLECULAR MARKERS FOR THE DIAGNOSIS OF HIGH-RISK HUMAN PAPILLOMAVIRUS INFECTION AND TRIAGE OF HUMAN PAPILLOMAVIRUS-POSITIVE WOMEN.

Infection with high-risk human papillomavirus (HPV) increases the likelihood of developing cervical cancer (CC). A plethora of cellular processes is required to produce pre-malignant lesions, which in turn may become malignant if left untreated. Those changes are induced by viral oncoproteins, which represent an ideal target to identify the viral presence, or by some particularities of the host that ultimately promote the establishment of CC.

Central nervous system metastasis from osteosarcoma: Case report and literature review.

Osteosarcoma is the most common primary malignancy of bone in children and young adults, the highest incidence peak is during adolescence and doesn't have any gender predominance. The main site of metastasis are the lungs and extrapulmonary cases are occasional. The incidence of metastasis in the Central Nervous System (CNS) is 2-6.

Epidemiological Data on the Nutritional Status of Cancer Patients Receiving Treatment with Concomitant Chemoradiotherapy, Radiotherapy or Sequential Chemoradiotherapy to the Abdominopelvic Area.

Cancer patients are particularly susceptible to undernourishment so associated weight loss is frequent. Approximately 15% of patients lose >10% of their usual body weight, 40-80% become undernourished, and about 20% die as a result. Well-nourished patients have a higher survival rate when compared with patients at risk of undernourishment (19.

Epidemiological Profile, Gastrointestinal Toxicity, and Treatment of Pelvic Cancers in Patients Managed with Radiotherapy to the Abdominal Pelvic Area.

Mexico has seen an increase in cancer prevalence in its entire population as well as particular age ranges, predominantly the older segment. The most frequently reported pelvic cancers in Mexico are cervical, endometrial, bladder, prostate, rectum, and anal canal. Approximately 80% of the population diagnosed with pelvic cancers present with locally advanced tumors and require concomitant chemoradiotherapy, sequential chemoradiotherapy, or radiotherapy alone.

Response Assessment of Ga-DOTA-E-[c(RGDfK)] PET/CT in Lung Adenocarcinoma Patients Treated with Nintedanib Plus Docetaxel.

Nintedanib is an oral angiokinase inhibitor used as second-line treatment for non-small cell lung cancer. New radiotracers, such as Ga-DOTA-E-[c(RGDfK)], that target αβ integrin might have an impact as a noninvasive method for assessing angiogenesis inhibitors. From July 2011 through October 2015, 38 patients received second-line nintedanib plus docetaxel.

ECOG is as independent predictor of the response to chemotherapy, overall survival and progression-free survival in carcinoma of unknown primary site.

The aim of the present study was to determine whether age, gender, functional status, histology, tumor location, number of metastases, and levels of the tumor markers, lactate dehydrogenase (LDH) and albumin, are poor prognostic factors for the response to chemotherapy in patients with carcinoma of unknown primary site. A total of 149 patients diagnosed with carcinoma of unknown primary site that was histologically confirmed, and treated with chemotherapy in the Oncology Hospital, National Medical Center, 'Century XXI' IMSS, Mexico City, Mexico during the period between January 2002 to December 2009, were carefully selected for the present study. The analysis of 149 patients diagnosed with carcinoma of unknown primary site revealed that the liver was the organ with the highest frequency of metastases (33.

Advanced Squamous Cell Carcinoma of the Head and Neck: The Current Role of Cetuximab.

We review clinical trials of squamous cell carcinoma of the head and neck (SCCHN) to address the current and potential uses of cetuximab (CTX). PubMed was reviewed to identify papers published between 2010 and 2016. The search terms used were "cetuximab" and "head and neck cancer.

Randomized, open-label trial evaluating the preventive effect of tetracycline on afatinib induced-skin toxicities in non-small cell lung cancer patients.

Background: Afatinib has shown long progression free survival and improvement in quality of life in advanced Non-Small Cell Lung Cancer (NSCLC) patients. Although afatinib causes acneiform rash, it can be manageable. Tetracyclines are usually used to treat it; nonetheless, there is no trial that evaluates their prophylactic efficacy on afatinib induced-skin toxicities (AIST).

High liposomal doxorubicin tumour tissue distribution, as determined by radiopharmaceutical labelling with (99m)Tc-LD, is associated with the response and survival of patients with unresectable pleural mesothelioma treated with a combination of liposomal doxorubicin and cisplatin.

Background: There are currently no available biomarkers for advanced pleural mesothelioma that determine which patients could benefit from a specific chemotherapy regimen.

Methods: Based on the results of a previously published phase II study, we associated the (99m)Technetium-labelled liposomal doxorubicin ((99m)Tc-LD) uptake value (75 % cut-off) with the response rate, progression-free survival and overall survival of patients treated with a combination of liposomal doxorubicin and cisplatin.

Results: Patients with tumours exhibiting increased (99m)Tc-LD uptake showed better response rates, progression-free survival and overall survival than those exhibiting lower uptake 73.

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.

[Third National Ovarian Consensus. 2011. Grupo de Investigación en Cáncer de Ovario y Tumores Ginecológicos de México "GICOM"].

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 first Mexican consensus of endometrial cancer. Grupo de Investigación en Cáncer de Ovario y Tumores Ginecológicos de México].

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%.

Testicular cancer in androgen insensitivity syndrome in a Mexican population.

Male pseudohermaphroditism and androgen insensitivity syndrome cases have an increased risk of developing testicular cancer due to many factors such as mutations, hormonal disturbances involving gonadotropins and cryptorchidism. We describe the clinical features, diagnosis and treatment of two cases with partial androgen insensitivity syndrome and testicular cancer development, which were handled at the National Cancer Institute of Mexico.

Staging, response to therapy, and restaging of lymphomas with 18F-FDG PET.

Background: We undertook this study to determine the diagnostic accuracy of (18)FDG after three cycles and at the end of chemotherapy in non-Hodgkin's lymphoma (NHL) or Hodgkin's lymphoma (HL). We also evaluated the role of (67)Ga, bone marrow aspiration (BMA), and computed tomography (CT) in monitoring lymphoma treatment.

Methods: (18)FDG, (67)Ga, BMA, and CT were performed before chemotherapy on 40 untreated patients.

Prognostic, predictive and therapeutic implications of HER2 in invasive epithelial ovarian cancer.

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.

Reducing the global breast cancer burden: the importance of patterns of care research.

Breast cancer treatment guidelines are not uniformly followed in clinical practice, with evidence for substantial variations in treatment patterns, quality of care, and patient outcomes among and within countries. The factors that drive treatment decisions are unclear. Furthermore, the impact of different treatment strategies on survival is poorly understood outside the clinical trial setting.

The global breast cancer burden: variations in epidemiology and survival.

Breast cancer is the most common type of cancer and the most common cause of cancer-related mortality among women worldwide. However, the burden is not evenly distributed, and, according to the best available data, there are large variations in the incidence, mortality, and survival between different countries and regions and within specific regions. Many complex factors underlie these variations, including population structure (eg, age, race, and ethnicity), lifestyle, environment, socioeconomic status, risk factor prevalence, mammography use, disease stage at diagnosis, and access to high-quality care.
