- Purpose: To investigate lymphatic drainage as measured by lymphoscintigraphy in the arms of patients undergoing either sentinel lymph node biopsy (SNB) or axillary lymph node dissection (ALND). Material and Methods: From January 2001 to December 2002, 30 patients with unilateral invasive breast carcinoma underwent breast-conserving surgery with SNB and 30 patients with ALND. All patients received radiotherapy to the breast. Lymphoscintigraphy was performed, and skin circulation, skin temperature, and arm volume were measured 2–3 years after radiotherapy. Results: None of the 30 patients who underwent SNB showed any clinical manifestation of lymphedema. Of the 30 patients undergoing ALND, six (20%) had clinical lymphedema, with an arm volume that was >10% larger on the operated than on the non-operated side ( P<0.01). Scintigraphically, visual analysis revealed lymphatic dysfunction in three patients, manifested as forearm dermal back flow. Two of these patients also had an increased arm volume. Quantitative analysis showed no differences between the groups, apart from a smaller amount of isotope in the axilla in the ALND group. There was no difference in skin circulation or skin temperature. Conclusion: Our study shows that lymph drainage in the operated arm compared with the non-operated arm was less affected by SNB than by ALND, and that morbidity associated with SNB was lower than with ALND. However, the results do not confirm our hypothesis that lymphoscintigraphy can reveal differences in lymph circulation that are not evident clinically in the form of manifest lymphedema. The most sensitive clinical method of assessing lymph drainage seems to be measurement of arm volume.

- Aim: As a means of staging the axilla with minimal surgical trauma, sentinel lymph node biopsy (SNB) has dramatically altered the management of early-stage breast cancer. The aim of this prospective multicentre study was to assess the safety of the method in cases of non-palpable tumours and in cases with an open biopsy prior to SNB. Method: In the period 1999-2001, 57 non-palpable breast cancers and 75 patients with diagnostic biopsy were collected prospectively to the first part of the study. In the second part, 745 patients with non-palpable breast cancers and 86 cases with prior open surgery diagnosed between 2000 and 2005 were followed up till the end of 2005. All patients in the first part of the study had an axillary clearance irrespective of sentinel node status, whereas in the second part axillary clearance was done only if the sentinel node was metastatic. Results: The detection rate was 95% in the group of non-palpable breast cancers, with a false negative rate of 5.6% (1/18), and the corresponding figures for the group with prior intervention were 96% and 10% (2/20). Two axillary recurrences, after a negative SNB at primary surgery, were found in the non-palpable group after 16 and 17 months, respectively. No axillary recurrence has been observed in the group of cancers with a prior open biopsy. Four women in the non-palpable group and two women with a diagnostic operation experienced distant metastases. Conclusion: We conclude that SNB is a safe procedure for women with non-palpable breast cancer, as well as after previous open diagnostic excision.
