Resumo
CONTEXT AND OBJECTIVE: Modifi ed radical
mastectomy is widely utilized in breast cancer
treatment. However, no prospective compari-
son 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 com-
pare these two modifi ed radical mastectomy
techniques, by analyzing their degrees of
diffi culty 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 modifi ed radical mastectomy
were included in the program, of whom 426 pa-
tients 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). Hospital-
ization 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 diffi culty for the two methods.
CONCLUSION: The removal of the pectoralis
minor muscle did not infl uence any of the vari-
ables studied. Therefore, either technique can be
performed, at the surgeon’s discretion.
