Contralateral axillary lymph node metastases at the time of primary breast cancer diagnosis: curative or palliative intent?

Contralateral axillary lymph node metastases (CAMs) in breast cancer patients are uncommon. CAM can be found at the time of primary breast cancer diagnosis or following prior treatment of breast cancer as a recurrence. This distinction may have important implications for disease staging and treatment selection. We report the case of a premenopausal woman with synchronous CAM. Despite extensive multimodality treatment, a recurrence was found 27 months after primary surgery. We reviewed the literature on histopathological tumor characteristics associated with CAM, lymphatic drainage of the breast to other sites than the ipsilateral axilla, and outcome of cases with CAM. This case contradicts current conceptions that CAM only develops from tumors with poor histopathological features. Emerging evidence shows that altered lymphatics play a central role in development of synchronous CAM. It is precisely this etiology that supports the concept that synchronous CAM occurs by lymphatic spread and not by hematogenous spread. Although controversial, treatment of synchronous CAM (without evidence of distant metastases) should therefore be of curative intent.

Effect of radiation therapy alone or in combination with surgery and/or chemotherapy on tumor and symptom control of recurrent rectal cancer.

PURPOSE: To define the value of radiotherapy alone or in combination with other treatment modalities in salvage and/or palliation of locally recurrent rectal cancer with or without concomitant distant metastases. PATIENTS AND METHOD: A series of 280 patients, treated between 1975 and 1990 was retrospectively reviewed. The patients were divided into 2 groups: 166 patients had a local recurrence only (group 1), 114 presented with simultaneously distant metastases (group 2). In group 1, 50 patients had only radiotherapy, 20 had radiation in combination with surgery, 68 patients had radiation and chemotherapy, and 28 patients had a combination of all 3 treatment modalities. In group 2 these numbers were 41, 7, 59 and 7, respectively. The median follow-up time was 11 months (1 to 118). RESULTS: The 2- and 5-year survival of group 1 were 33% and 12%. In group 2 the 2-year survival was 9%. The 2- and 5-year symptom-free survival for both groups were 18%/12% and 4%/0%, respectively. There was no significant difference in survival and symptom-free survival between treatment including concomitant 5-FU or 5-FU once a week and treatment without chemotherapy. In the combined treatments which included surgery there was a longer survival and symptom-free survival. In both groups a subanalysis of the patients who had radiation only showed a dose-response relationship for symptom-free survival. This was not the case for survival. CONCLUSION: In local recurrence of rectal cancer without detectable distant metastases, radiotherapy and/or surgery have value toward survival and symptom-free survival. Further intense efforts in preventing the local recurrence by improving primary treatment are warranted.
