Estudo da frequência das neoplasias intra-epiteliais cervicais em mulheres portadoras do vírus da imunodeficiência humana

Dentre as manifestações ginecológicas mais importantes nas mulheres soropositivas para o HIV, estão o câncer do colo uterino e as neoplasias intra-epiteliais cervicais que lhe são as lesões precurssoras. Neste estudo foram analisadas 36 mulheres soropositivas para o vírus da imunodeficiência humana e 54 soro negativas, com a finalidade de analisar a freqüência de lesões precursoras do câncer uterino cervical. Todas as pacientes foram submetidas ao exame clínico ginecológico, colheita de colpocitologia cérvico-vaginal, colposcopia e à biópsia genital quando o exame colposcópico revelava achados anormais. Nas pacientes soropositivas foram quantificados os linfócitos com receptores CD4 e verificado a aderência ao esquema antiretroviral. Os resultados demonstraram que a freqüência das neoplasias intra-epiteliais cervicais foi semelhante nos dois grupos estudados. Observamos ainda que a maioria das pacientes soropositivas apresentavam contagem de CD4 acima de 200 células / mm3, ou seja eram consideradas imunocompetentes. E que trinta e três pacientes das trinta e seis estudadas eram aderentes ao esquema antiretroviral. Concluímos que as mulheres HIV soropositivas consideradas imunocompetentes e em uso de antiretrovirais apresentaram freqüência de neoplasias intraepiteliais cervico-uterinas semelhantes às mulheres soro negativas incluídas neste estudo. Observamos, ainda, que o HPV é importante cofator no desenvolvimento das neoplasias intra-epiteliais cervicais.

Frequency of various types of neoplasia in a group of acromegalic patients

OBJECTIVE: To determine the frequency of colon cancer, primary hyperparathyroidism, thyroid tumor, and skin cancer in all acromegalic patients in follow-up at the Clinics Hospital - Botucatu Medical School, from 2005 to 2011. SUBJECTS AND METHODS: These patients were evaluated retrospectively for colon cancer, primary hyperparathyroidism, dermatological, and thyroid tumors. RESULTS: Of 29 patients included at the beginning of the study, two were excluded. Among 19 patients submitted to colonoscopy, one presented colon adenocarcinoma (5%). Thyroid nodules were present in 63% of patients, and papilliferous carcinoma was confirmed in two patients (7,7%). Four patients were confirmed as having primary hyperparathyroidism (15%). The most common dermatologic lesions were thickened skin (100%), acrochordons (64%), epidermal cysts (50%), and pseudo-acanthosis nigricans (50%). Only one patient presented basal cell carcinoma. CONCLUSION: Although a small number of acromegalic patients was studied, our findings confirm the high frequency of thyroid neoplasias and primary hyperparathyroidism in this group of patients.

Neoplasia mamária em cadelas: aspectos clínico-cirúrgicos

Oncology is presenting an important role in clinical practice as a speciality in recent years in Veterinary Medicine. Mammary gland tumors are detected mainly in old and middleaged bitches that are sexually intact or spayed and the caudal abdominal and inguinal mammary glands are the most affected and they present a percentage up to 75% of malignancy. The majority of dogs with mammary neoplasms are clinically healthy at the time of diagnosis and the tumors can be identified by the owner or a professional during a routine physical examination. Cytological examination of fine needle aspirates can be performed. This procedure is easy and low cost and some criteria that may indicate malignancy are evaluated, however to obtain a definitive diagnosis is performed histopathology of the excised tissue or from biopsy. Regional lymph nodes are the first lymph node to receive lymphatic drainage from the neoplasm. They are at the highest risk of regional metastasis, while the lung is the most common site for distant metastasis. Determining the clinical stage enables the definition of the extension of the tumor. As a consequence, this allows a prognosis to be established and treatment to be planned. The type of therapy to be chosen incites controversy since there are numerous treatment options described, but the surgery is the chosen treatment. However, surgery is not always effective for malignant tumors, and recurrences may occur and in these cases, auxiliary chemotherapy treatments are used. The prognosis for animals that have mammary tumors depends on several factors, such as: size, stage, type of tumor cells and clinical behavior of the tumor, age and medical condition of the animal, and presence of metastasis. Because of this, more detailed studies are needed based on epidemiological surveys in order to provide more informations about risk factors, prevalence and follow-up after treatment of mammary...

Response to Chemotherapy in Overweight/Obese Patients With Low-Risk Gestational Trophoblastic Neoplasia

Objective Despite rising global obesity rates, the impact of obesity on gestational trophoblastic neoplasia (GTN) remains uninvestigated. This study aimed at investigating whether overweight/obesity relates to response to chemotherapy in low-risk GTN patients.Methods This nonconcurrent cohort study included 300 patients with International Federation of Gynecology and Obstetrics-defined postmolar low-risk GTN treated with a single-agent chemotherapymethotrexate or actinomycin-D (actD)between 1973 and 2012 at the New England Trophoblastic Disease Center. Chemotherapy dosing was based on actual body weight regardless of obesity status, except for 5-day courses or pulse regimens of actD. Patients were classified as overweight/obese (body mass index [BMI] 25 kg/m(2)) or non-overweight/obese (BMI <25 kg/m(2)). Information on patient characteristics and response to chemotherapy (need for second-line chemotherapy, reason for changing to an alternative chemotherapy, number of cycles, need for combination chemotherapy, and time to human chorionic gonadotropin remission) was obtained.Results Of 300 low-risk GTN patients, 81 (27%) were overweight/obese. Overweight/obese patients were older than the non-overweight/obese patients (median age: 30 vs 28 years, P = 0.004). First-line therapy using actD was more frequent in overweight/obese patients (6.2% vs 1.4%, P = 0.036). Resistance and toxicity were similar between groups. No significant difference in the number of chemotherapy cycles needed for remission or time required to achieve remission was found between groups.Conclusions No association between overweight/obesity and low-risk GTN outcomes was found. Current chemotherapy dosing using BMI seems to be appropriate for overweight/obese patients with low-risk GTN.
