Neoadjuvant chemotherapy or chemotherapy and endocrine therapy in locally advanced breast carcinoma. A prospective, randomized study

Forty-nine patients with locally advanced breast carcinoma were prospectively randomized to be treated with either CMF or CMF plus T for four courses, both before and after mastectomy. The overall clinical objective remission rate for induction treatment was similar (71% with CMF and 64% with CMF + T). The time to progression or recurrence of the disease was also not significantly different between the two groups. Overall survival was shorter after CMF + T treatment (median value of 41.5 months) than after CMF treatment alone (median value of 79.7 months; p = 0.05). Even after progression or recurrence, survival was shorter for patients receiving CMF + T than those receiving CMF (median values of 7.5 and 17.3 months, respectively; p = 0.09). These results show that the addition of T to CMF in the treatment of locally advanced breast carcinoma, before and after mastectomy, offers no advantage for improving the overall response rate. Moreover, this addition may have an adverse impact on survival in this disease setting.

[Analysis of prognostic factors in 106 cases of carcinoma of the rhinopharynx treated with cobalt teletherapy]

A series of 106 patients affected with nasopharyngeal carcinomas and treated by definitive external irradiation from January 1975 to December 1986 was retrospectively reviewed. The median follow-up, from the end of the treatment, was 43 months (range 24-90). The nasopharynx received not less than 60 Gy to the midplane: the clinically negative neck (N0) was treated with a total dose of 50 Gy and the patients who had N1-3 disease received not less than 60 Gy. Thirty-eight patients had a recurrence in the irradiated areas (31 in the nasopharynx, and 7 in the neck); 17 patients developed distant metastases. Disease-free survival at 60 months was 42%. The most significant prognostic factor (p less than 0.05) was the presence of advanced neck involvement (N2-3), since most of the lymphatic and distant recurrences were observed in this group of patients. The overall results did not reveal but slight differences in the survival according to histology, even though patients with undifferentiated carcinomas had a local recurrence rate significantly lower than those with squamous cell carcinomas. Our findings suggest that patients with N2-3 neck diseases or with locally advanced involvement (T3-4) be treated by adjuvant chemotherapy in order to decrease the risk of local and distant relapses.

Algodystrophy and related psychological features

This work wants to emphatize the role of the personality in the development of the algodystrophic syndrome. For this purpose 13 patients affected by algodystrophy of the hand and 23 with brachial plexus lesions were invited to fill in the M.M.P.I.; the patients suffering from algodystrophy reached higher scores on the Depression, Hysteria and Hypocondria scales.

Problems in evaluating response of primary breast cancer to systemic therapy

The evaluation of the response of primary breast cancer to systemic therapy is difficult. Evaluable primary lesions may be assessed both by physical and by mammographic examination. In this study, response to therapy was evaluated after 4 cycles of CMF or CMF plus tamoxifen in 49 patients with locally advanced breast cancer entering a prospective randomized trial. In 35 patients response was evaluated by both physical examination and mammography. In some cases there was disagreement between physical examination and mammography in quantifying the magnitude of response. In 8 of 35 (22.9%), the overall response was overestimated by physical examination versus mammography, while in 3 of 35 (8.6%) the reverse was true. Taking into consideration different criteria in attributing the overall response, i.e. selecting physical examination only, mammography only, or the most favorable or the least favorable response between the two methods of assessment, the objective remission rates were 65.7%, 54.3%, 71.4% and 45.7%, respectively. The data suggest that both physical examination and mammography should be used in evaluating the response of primary breast cancer to a systemic treatment. Should these two methods yield contrasting results, the data obtained with each method should be reported. The best observed response may be employed in determining the overall response.
