PURPOSE: To evaluate changes in the venous axillary-subclavian and lymphatic systems of women with lymphedema after axillary lymphadenectomy for breast cancer treatment. METHODS: This was a case series involving 11 women with unilateral upper limb lymphedema after axillary lymphedenectomy for the treatment of breast cancer. The study was carried out in the Mastology Program of the Clinical Hospital of the Federal University of Goiás, Goiânia, GO, during the period between March 2010 and March 2011. Doppler velocimetry ultrasonography was used to detect the presence of venous changes in the subclavian and axillary veins. Lymphatic changes were evaluated by lymphoscintigraphy in both upper limbs. Fisher's exact test was used for the comparison between limbs. RESULTS: Subclavian vein flow volume in the upper limb with lymphedema was significantly different from that in the contralateral limb (p<0.001), 54.6% of the women had increased flow. In the axillary vein, 45.4% had increased flow and 45.4% had decreased flow, with a statistically significant difference (p<0.01) between limbs. Compared to the contralateral limb, significant lymphatic changes (p<0.05) were also found in the vessel route (not visualized), number of lymphatic vessels (none), axillary lymph nodes (absent) and dermal reflux (present). In the contralateral upper limb without lymphedema, no venous or lymphatic alterations were encountered. CONCLUSION: The women subjected to axillary lymphadenectomy for the treatment of breast cancer presented both venous and lymphatic changes in the upper limb with lymphedema.

PURPOSE: To analyze the temporal changes of breast cancer staging at diagnosis among women living in Goiânia, Goiás, Brazil, between 1989 and 2003. METHODS: Retrospective and descriptive study in which the cases were identified from the Population-Based Cancer Registry of Goiânia for the period from 1989 to 2003. The variables studied were age, diagnostic method, topographic sublocation, morphology and breast cancer staging. Frequency analyses were carried out on the variables and means, and the medians for the age were determined. The SPSS® 15.0 software was used for statistical analyses. RESULTS: A total of 3,204 breast cancer cases were collected. The mean age was 56 years (sd±16 years). With regard to clinical staging, 45.6% of the cases were found to be localized in the breast, with an increased rate of 19.25% between the first and the third five-year period (p<0.001; CI 95%=0.14-0.23) and 10.2% of cases were with distant metastases. However, a reduction of 17.74% for metastatic cases in the same interval (p<0.001 e CI 95%=0.14-21) was observed. The in situ case rate was 0.2% in 1989-1993 and increased to 6.2% in 1999-2003 (p<0.001, IC95%=4.9-7.4). CONCLUSION: The diagnostic profile of breast cancer in the city of Goiânia is changing. Substantial increases in the number of early breast cancer cases are being found in relation to the number of advanced cases.
