ABSTRACT

OBJECTIVE: This randomized clinical trial evaluated the possibility of not draining the axilla following axillary dissection. METHODS: The study included 240 breast cancer patients who underwent axillary dissection as part of conservative treatment. The patients were divided into two groups depending on whether or not they were subjected to axillary drainage. ClinicalTrials.gov: NCT01267552. RESULTS: The median volume of fluid aspirated was significantly lower in the axillary drainage group (0.00 ml; 0.00 - 270.00) compared to the no drain group (522.50 ml; 130.00 - 1148.75). The median number of aspirations performed during conservative breast cancer treatment was significantly lower in the drainage group (0.5; 0.0 - 4.0) compared to the no drain group (5.0; 3.0 - 7.0). The total volume of serous fluid produced (the volume of fluid obtained from drainage added to the volume of aspirated fluid) was similar in the two groups. Regarding complications, two cases (2.4%) of wound dehiscence occurred in the drainage group compared to 13 cases (13.5%) in the group in which drainage was not performed, with this difference being statistically significant. Rates of infection, necrosis and hematoma were similar in both groups. CONCLUSION: Safety rates were similar in both study groups; hence, axillary dissection can feasibly be performed without drainage. However, more needle aspirations could be required, and there could be more cases of wound dehiscence in patients who do not undergo auxiliary drainage.

ABSTRACT

CONTEXT AND OBJECTIVE: Modified radical mastectomy is widely utilized in breast cancer treatment. However, no prospective comparison has yet been made between the Madden technique (preservation of the pectoralis minor muscle) and the Patey technique (resection of this muscle). The aim of this work was to compare these two modified radical mastectomy techniques, by analyzing their degrees of difficulty and complications. DESIGN AND SETTING: Randomized trial at the Breast Unit of Hospital Araújo Jorge, Goiás; and Faculdade de Medicina da Universidade Federal de Goiás. METHODS: 430 patients with breast cancer with an indication for modified radical mastectomy were included in the program, of whom 426 patients were available for analysis (225 allocated to Patey and 201 to Madden). The chi-squared and Student t tests were used for analysis. RESULTS: The patients' demographics were well balanced between the two groups. The mean duration of the surgical procedures was 105 (± 29.9) and 102 minutes (± 33), for the Patey and Madden groups, respectively (p = 0.6). Hospitalization duration was 2.3 days for both groups. The mean number of lymph nodes resected was 20.3 (± 7.6) for Patey and 19.8 (± 8.1) for Madden (p = 0.5). There were no differences in terms of vascular or nerve sections, hematomas or infections. The surgeons reported the same degree of difficulty for the two methods. CONCLUSION: The removal of the pectoralis minor muscle did not influence any of the variables studied. Therefore, either technique can be performed, at the surgeon's discretion.


CONTEXTO E OBJETIVO: A mastectomia radical modificada continua a ser amplamente usada para o tratamento de câncer de mama. Porém, até agora, a preservação do músculo peitoral secundário (técnica de Madden) não foi prospectivamente comparada à técnica de Patey. O objetivo deste trabalho foi comparar as duas técnicas de mastectomias radicais modificadas, analisando o grau de dificuldade e as complicações. TIPO DE ESTUDO E LOCAL: Estudo randomizado, realizado na Unidade de Mama do Hospital Araújo Jorge, Faculdade de Medicina da Universidade Federal de Goiás, Goiás, Brazil. MÉTODOS: 430 pacientes portadoras de câncer de mama com indicação de mastectomia radical modificada foram incluídas no programa. Foram disponíveis para análise 426 pacientes, das quais 225 alocadas no grupo Patey e 201 no grupo Madden. A análise foi feita por intenção de tratamento, usando-se o Qui-quadrado ou o teste t de Student, quando aplicáveis. RESULTADOS: A distribuição das características demográficas pacientes foi semelhante entre os grupos. A duração média da cirurgia foi de 105 minutos (DP ± 29.9) e 102 (DP ± 33) para o grupo Patey e Madden, respectivamente (p = 0,6). O tempo de internação foi de 2,3 dias para ambos os grupos. A média de linfonodos ressecados foi de 20,3 (DP ± 7,6) para Patey e 19,8 (DP ± 8,1) para Madden (p = 0,5). Não houve diferenças entre as complicações vasculares, nervosas, hematomas, infecções, bem quanto à dificuldade relatada pelo cirurgião. CONCLUSÃO: A retirada do músculo pequeno peitoral não influenciou nenhuma das variáveis estudadas. As técnicas de mastectomias radicais modificadas, Patey e Madden, foram semelhantes em todos os critérios observados, podendo ser executadas de acordo com a preferência do cirurgião.

ABSTRACT

Com o objetivo de avaliar a sobrevida de pacientes com câncer de mama localmente avançado, 71 pacientes com carcinoma de mama, estadio clínico III, foram submetidas à quimioterapia neo-adjuvante com o esquema FACV (ciclofosfamida 400 mg/m2, 5-fluorouracil 400 mg/m2, adriamicina 10 mg/m2 e vincristina 1 mg/m2). Foram realizados 6 ciclos, semanalmente, seguidos de mastectomia e mais 11 ciclos quinzenalmente. As curvas de sobrevida foram calculadas pelos estimadores de Kaplan e Meier. Como resultado, a mediana de seguimento das pacientes foi de 24 meses, variando de 1 a 93 meses. Aos 60 meses, a sobrevida livre de recidiva local foi de 60 por cento, a sobrevida livre de doença foi de 26 por cento e a sobrevida total foi de 52 por cento. A mediana de tempo para a recidiva local foi de 14 meses e a mediana de tempo para o aparecimento de metástases foi de 16 meses. Houve 8,5 por cento de abandono de tratamento pré-operatório. Assim, conclui-se que a quimioterapia neo-adjuvante, com o esquema proposto, mostrou ser uma boa alternativa no controle do câncer de mama, com alto índice de adesäo ao tratamento e um controle sistêmico satisfatório para pacientes diagnosticadas com doença localmente avançada.
