We reviewed the complete axillary dissection specimens of 136 patients with stage I-II breast cancer to clarify the distribution of axillary lymph node metastases in this disease. Our series included 71 patients undergoing axillary dissection as part of a modified radical mastectomy (MRM) and 65 patients undergoing axillary dissection in conjunction with conservative surgery of the breast and definitive postoperative breast radiotherapy (CAD). These two groups of patients were comparable according to age, menopausal status, tumor size, and clinical stage. In all patients the pectoralis minor muscle was excised and all axillary tissue removed. Each specimen contained a median of 23 lymph nodes. The axillary levels (I, II, III) were determined according to the relationship of axillary tissue to the pectoralis minor muscle (lateral, inferior, medial). Thirty-nine percent of the lymph nodes were contained in level I, 41% in level II, and 20% in level III. There were no significant differences noted in the number of lymph nodes or in the distribution of lymph nodes according to axillary level between dissections performed as part of the MRM or those done as a single procedure (CAD). Sixty-five patients (47.8%) had one or more positive lymph nodes in their axillary specimen. The clinical and pathologic stage was determined and compared for all patients. Among patients judged to have a clinically negative axilla, 37.6% had histologically positive lymph nodes (clinical false-negative rate). For patients with a clinically positive axilla, 11.1% had, histologically, no evidence of metastatic disease (clinical false-positive rate). When the distribution of lymph node metastases according to axillary level was studied, it was found that 29.2% of lymph node-positive patients (or 14.0% of all patients) had metastases only to level II and/or III of the axilla, with level I being negative (skip metastases). This incidence of skip metastases was greater among clinically node-negative than among clinically node-positive patients, but was not related to the size or location of the primary tumor in the breast. In addition, it was found that 20.0% of lymph node-positive patients (or 9.6% of all patients) were converted from three or fewer to four or more positive nodes by analysis of lymph nodes contained in levels II and III. This conversion from three or fewer to four or more positive nodes was due primarily to information contained in level II, with level III contributing to a smaller degree.(ABSTRACT TRUNCATED AT 400 WORDS)

The impact of primary irradiation treatment of localized breast cancer on the ability to administer systemic adjuvant chemotherapy.

The impact of primary irradiation of localized breast cancer on the ability to administer Adriamycin-cytoxan adjuvant chemotherapy to patients with stage II breast cancer was examined. Patients were prospectively randomized to receive either irradiation or mastectomy as local therapy and did not differ with respect to other prognostic variables that might influence tolerance to chemotherapy. All of the patients received chemotherapy dose escalations (or reductions) until maximal tolerated drug doses were established. Patients receiving irradiation had minimally greater myelosuppression which was nearly totally explainable by lymphopenia. Irradiated patients required dose reduction nearly twice as often as mastectomy patients although commonly their dose could be reescalated. Patients managed with radiotherapy received slightly less drug than patients treated with mastectomy when treated to an identical degree of bone marrow suppression. The primary management of breast cancer by irradiation does not induce substantial changes in the ability of patients to tolerate adjuvant chemotherapy.

Psychosocial and physical outcomes of primary breast cancer therapy: mastectomy vs excisional biopsy and irradiation.

Thirty-eight patients treated for primary breast cancer as part of a prospective randomized clinical trial were questioned retrospectively as to their psychosocial adaptation to treatment. Twenty patients had received mastectomy and eighteen had received excisional biopsy plus radiation of the intact breast. Aside from body image concerns, there were no marked psychosocial differences detected between these groups. Previous studies emphasizing serious psychological problems in mastectomy patients and fewer such problems in nonmastectomy patients may be influenced by biases that are not present in a randomized study design.

Breast reconstruction using tissue expanders.

Breast reconstruction options are available to virtually all women undergoing mastectomy. Breast reconstruction may increase the woman's self-esteem and foster a more positive body image. Tissue expansion provides a means of developing breast symmetry with minimal surgical intervention. It can be used when the skin and soft tissue remaining after mastectomy are of good quality but inadequate quantity. The nurse's role encompasses physical and psychological support and patient education.
