Localization of the sentinel lymph node in breast cancer by combined lymphoscintigraphy, blue dye and intraoperative gamma probe.

Axillary lymph node status represents the most important prognostic factor in patients with operable breast cancer. A severe limitation of this technique is the relatively high rate of false negative sentinel lymph nodes (>5%). We studied 284 patients suffering from breast cancer; 264 had T1 tumors (16 T1a, 37 T1b and 211 T1c), while 20 had T2 tumors. All patients underwent lymphoscintigraphy 18-h before surgery. At surgery, 0.5 mL of patent blue violet was injected subdermally, and the sentinel lymph node (SN) was searched by gamma probe and by the dye method. The surgically isolated SN was processed for intraoperative and delayed examinations. The SN was successfully identified by the combined radioisotopic procedure and patent blue dye technique in 278/284 cases (97.9%). Analysis of the predictive value of the SN in relation to the status of the axillary lymph nodes was limited to 191 patients undergoing standard axillary dissection irrespective of the SN status. Overall, 63/191 (33%) identified SNs were metastatic, the SN alone being involved in 37/63 (58.7%) patients; a positive axillary status with negative SN was found in 10/73 (13.7%) patients with metastatic involvement. In T1a-T1b patients the SN turned out to be metastatic in 9/53 patients (17.0%). In 7/9 patients the SN was the only site of metastasis, while in 2/9 patients other axillary lymph nodes were found to be metastatic in addition to the SN. None of the 44 patients in whom the SN proved to be non-metastatic showed any metastatic involvement of other axillary lymph nodes. Our results demonstrate a good predictive value of SN biopsy in patients with breast cancer; the predictive value was excellent in those subjects with nodules smaller than 1 cm.

Predictive value of some clinical and pathological parameters on upper level axillary lymph node involvement in breast cancer.

The role of radical axillary dissection in breast cancer management is presently under discussion. In this study we have evaluated the relationship between the pattern of metastatic axillary lymph node involvement by level and some of the main prognostic factors (age of the patient, size, grading, estrogen receptor and progesterone receptor status of the primary tumor) in 185 patients with operable breast cancer. The III level appeared to be involved in 31 (16.8%) out the 108 patients with axillary lymph nodes positive for metastases. A discontinuous pattern of axillary involvement (skip metastases) was observed in about 10% of cases. Logistic regression analysis of the data shows that only G3 is significantly correlated with the risk of III level invasion (p less than 0.05). We conclude that, at present, a selection of possible candidates for a less than radical axillary dissection is not as yet feasible. Since the risk for III level invasion cannot be sufficiently defined.

Surgical treatment of thyroid cancer.

Surgery is the treatment of choice for thyroid cancer, often followed by I131 and thyroid hormone to control the local residual tumor and distant metastasis. Hundred and sixty-two patients with thyroid disease underwent surgery at the Division of Surgical Oncology of the Cancer Institute in Genoa. Thirty cases presented no malignant hot thyroid nodules, 37 of the other 132 cases were cancers (28%). In 23 cases (62%), the pathological diagnosis was papillary carcinoma, in ten cases (27%) follicular carcinoma, in four (11%) medullary carcinoma. In 13 cases (35%) (ten papillary carcinoma, two follicular carcinoma, one medullary carcinoma) the lesion was multicentric. Our data suggest that total thyroidectomy, performed in two steps, in most cases does not carry important post-operative morbidity but offers the greatest potential for cure. In our cases only one patient died (of the cancer). After radical surgery it is possible to detect and treat metastases by I131.
