Avaliação da resposta à quimioterapia primária em amostra de mulheres brasileiras com tumores de mama localmente avançados

PURPOSE: to evaluate the loco-regional response to primary chemotherapy in patients with breast cancer at stages II and III. METHODS: a retrospective and analytical clinical study carried out in 97 patients with an average age of 52.2 years old, with breast cancer at stages II and III, attended from January 1993 to December 2004, and submitted to 3 to 4 cycles of primary chemotherapy with 5-fl uorouracil - 500 mg/m2, epirubicin - 50 mg/m2 and cyclophosphamide - 500 mg/m2 or doxorubicin - 50 mg/m2 e cyclophosphamide - 500 mg/m2, and then to loco-regional surgical conservative or radical surgical treatment. Chi-square and Fisher's exact tests were used to study the association among the variables (age, menopausal state, pre-chemotherapy tumoral volume, axillary condition, stage, therapeutic scheme and number of cycles), while Pearson's correlation coefficient was used for the quantitative variables (tumoral volume according to the anatomo-pathological study and the post-chemotherapy clinical tumoral volume. The significance level was 5%. RESULTS: there were 56.8% of cases at stage II and 43.2% at stage III. Approximately 50% of the patients received FEC50 and 50% AC. Objective clinical response with primary chemotherapy was obtained in 64.9% of the cases. Full clinical response occurred in 12.3% of patients, while full pathological response occurred in 10.3% of the cases. CONCLUSIONS: there was a statistically significant correlation between the number of cycles and the response to primary chemotherapy. Patients who received 4 cycles had better response than those who received 3 cycles. There was also a statistically significant concordance between the evaluation through clinical examination of the response to primary chemotherapy and the pathological findings. No statistically significant correlation was observed concerning age, menopausal status, tumoral volume, and pretreatment of axillary damage.

Periodontal condition in patients with rheumatoid arthritis

The purpose of this clinical study was to investigate if periodontal disease and rheumatoid arthritis (RA) are associated. The study included 39 RA patients (test group) and 22 age- and gender-matched healthy individuals (control group). Questionnaires on general and oral health were applied and a complete periodontal exam, including visible plaque, marginal bleeding, attachment loss (AL) and number of teeth present, was also performed by a single calibrated examiner. Diabetes mellitus patients and smokers were excluded. RA patients had fewer teeth, higher prevalence of sites presenting dental plaque and a higher frequency of sites with advanced attachment loss. Although the prevalence of dental plaque was higher in the test group (Chi-square test, p = 0.0006), the percentage of sites showing gingival bleeding was not different (Fisher's exact test, p > 0.05). Based on our results, we suggest that there is an association between periodontal disease and RA.

Estudos de medicamentos biosimilares

In Brazil, the registration of new drugs is carried out only when the regulatory agency (Anvisa, acronym in Portuguese) is fully satisfied with the evidence of their quality, efficacy and safety, presented by a pharmaceutical industry that strive for this registration. With the patent expiration, pharmaceutical companies are attracted to produce biological medicines called biosimilar or biogenerics or simply generics, whose approval may result in reduced treatment costs. But it is necessary that the biosimilar be, at least, equally efective and safe and without contaminants in relation to the original. Recent consensus guidelines aim to establish criteria for efcacy and safety of these medicines. Preclinical studies in vitro and in vivo, the origin of raw materials and clinical studies phase I, II and III are recommended for biosimilar medicine registration in the international market. Low molecular weight heparins are found in this situation. In this review we specifcally addressed this type of medicine, which could serve as a benchmark for other biosimilar medicines.
