Primary tumor receptorial status and axillary metastases: their prognostic significance.

Data on the prognostic value of receptorial status are controversial. On the basis of our results, receptorial status has no significance as an independent role; only the number of involved nodes and hormonal therapy have this prognostic role. Free of disease survival curves according Kaplan and Meier show that there are no statistically significant differences either in patients with low neoplastic recurrences (pN0) or in those patients with high risk (pN1) among women with tumor ER+ and ER-. Among 291 pN0 patients there was no relation between receptorial status (negative from 3 to 9 fmol/mg) and results of therapy on the follow-up. Among 248 pN1 patients therapy with tamoxifen had an influence on free interval both in the group with a low receptorial status and in particular in that with high receptorial level; no effects of therapy on the ER- patients. In the group of 248 pN1 patients with high receptorial status, the therapy was more successful in the group with a medium lymph nodal risk (from 1 to 3 positive nodes) and also in the group with G1 or G2. With regard to the study of the relation between lymph nodal metastases and receptorial status, we can state that lymph nodal levels data gives the main prognostic factor of risk. Therefore lymphadenectomy involving the three lymph nodal levels appears to be the crucial point in diagnostic and therapeutic surgical strategy of breast carcinoma.

Surgical strategy management following lymph nodal positivity at the three levels (a retrospective and perspective study).

The purpose of this study is to evaluate the type of distribution, regular or irregular, of metastases in lymph nodes of I, II and III level. We inted also to establish if the levels of lymph nodal areas represent an evaluation index of prognostic risk more effective than other ones. The results evidenced that in 19.2% of all the classes N+ metastases were not increasing regularly from the level I to the level III. The influence of seven factors on disease free survival has been evaluated: pT, pN, number of metastatic nodes, ER+ or ER-, PgR+ or PgR-, grading, metastatic level at axillary lymph nodes. The present report points out that only the extent of tumor and lymph nodal level have a statistically significant influence on disease free survival. Comparison among disease free survival curves stage N0 with N+ at I level and with N+ at II level revealed that there is no significant difference of survival among these classes, while the comparison between the first 3 classes and N+ at III level is statistically significant.

The influence of hormone receptors and hormonal adjuvant therapy on disease-free survival in breast cancer: a multifactorial analysis.

The prognostic value of estrogen (ER) and progesterone (PgR) receptor status and the influence of hormonal adjuvant therapy on disease-free survival (DFS) in breast cancer were evaluated in 680 women after radical and modified radical mastectomy. The effect of 17 variables, including clinical data, TNM, hormone receptor status, histology and adjuvant therapy, on the DFS observed was analyzed, using a multivariate proportional hazard model. Multifactorial analysis revealed that DFS was strongly related to the number of positive axillary nodes (P less than 0.001) and the histological grade of the tumor (P = 0.05). Moreover, the DFS of ER-positive patients with node involvement was significantly improved by hormonal adjuvant therapy (tamoxifen). Combination of adjuvant chemotherapy with hormonal therapy did not enhance its effectiveness. Recurrence rates of either node-negative or ER-negative patients were not affected by either adjuvant therapy. When no systemic therapy was given, no significant relationship between ER or PgR content of the tumor and the DFS was observed. These findings suggest that hormone receptor status is not an independent prognostic factor but provides reliable information on responsiveness to adjuvant hormonal therapy which is very effective in patients selected on the basis of ER assay.

[Retrosternal thyroid cancers. Considerations on 25 cases].

Intrathoracic thyroid cancer is an unusual finding, and few reports are available on this item. Literature data have been reviewed, and some considerations on epidemiologic characteristics of the disease and on its treatment were gained from an analysis of reports based on the files of I Surgical Clinic of the University of Turin, Surgical service of the Oncological Department of the S. Giovanni Battista Hospital and II Pathological Anatomy Service of the University of Turin. No correlation was found between previous thyroid disease, sex, histological findings, previous radiotherapy and incidence of the disease. Older age at the onset and recurrent laryngeal nerve lesions are frequently associated with intrathoracic thyroid cancer; papillary carcinoma is rarely found. Intrathoracic situation is not likely, in Author's opinion, to affect the long term prognosis more than usual risk factors.
