Estrogen and progesterone receptors as prognostic factors in breast cancer.

The relation between estrogen receptors (ER) and/or progesterone receptors (PgR) and some clinical factors such as tumor size, axillary node involvement, histological tumor grade, and disease-free interval (DFI) in 500 patients with operable (TNM stage I-III) breast cancer was studied. ER-positive (ER+) tumors were commoner in older patients, whereas PgR-positive (PgR+) tumors were similarly distributed within the age groups. The concentration of ER+ protein also increased with age in contrast to PgR+ protein concentration. However, receptor status was not associated with menopausal status independently of age. Axillary node involvement influenced neither ER nor PgR status, but there was a statistically significant relation between tumor size and positivity of ER or PgR. There was no association between histologic tumor grade and either steroid receptor phenotype. DFI was longer in patients with ER+ than those with ER- tumors, independently of axillary nodal status. The positivity of PgR in patients with ER+ tumors contributed to an even longer DFI, suggesting that the combination of ER/PgR is a better indicator of DFI than ER or PgR alone.

Histopathologic and histoenzymatic observations in carcinomas treated with human leukocyte interferon.

In this study histologic and histochemical examinations were performed on the bioptic material of 30 cases of head and neck tumors and 34 cases of uterocervical carcinomas after treatment with human leukocyte interferon (HLI). Particular attention was paid to the interaction between stromal and neoplastic cells as a possible host response to the treatment with interferon. In addition to tumor biopsies, regional lymph nodes were also examined microscopically. Stromal cells (macrophages, T and B lymphocytes, and granulocytes) were detected by enzyme-histochemical methods. Histologic and histochemical criteria for classification of tumor biopsies into five groups included the frequency, the cellular composition of peritumoral stroma, the grade of macrophage infiltration into the tumor (expressed quantitatively), and cytologic changes, followed by the regression of tumor. The overall appraisal of patients with cervical carcinoma based on histopathologic and chemical criteria showed the positive effect of HLI therapy in 70% of the cases; observations of head and neck carcinoma treated with HLI showed positive effects in 82% of the cases.

Application of human leucocyte interferon in patients with urinary bladder papillomatosis, breast cancer, and melanoma.

Eight patients with malignant papillomaosis of the bladder, four with breast cancer, and two with malignant melanoma, all of whom had a poor prognosis, were treated with injection of crude human leucocyte interferon (HLI) into the tumour or the adjacent tissue and in some cases with intramuscular HLI injection also. All tumours showed complete or partial regression after treatment for up to 6 months. One patient with breast cancer died from distant metastases; all other patients in the trial were recurrence-free after 3--30 months of follow-up.

Human leukocyte interferon in therapy of patients with urinary bladder papillomatosis, breast cancer, and melanoma.

The authors report the result of local and parenteral applications of human leukocyte crude interferon in the therapy of eight patients with urinary bladder papillomatosis, four patients with breast cancer, and two patients with melanoma. The doses and effects of treatment are presented in tables. Clinical application of human leukocyte interferon (HLI) to these three types of malignant tumors has yielded encouraging results. The authors believe that investigations on HLI applications to some malignant tumors should continue because the results obtained indicate that interferon possesses not only an antiviral but also an antitumor activity.

BCG immunotherapy in previously treated malignant melanoma patients.

Eighteen patients with histologically confirmed metastatic malignant melanoma were treated with intradermal BCG. Before starting immunotherapy their immunocompetence was tested in vivo and in vitro. Four of 15 (27%) achieved complete regression, and two (13%) a regression of more than 50%, after systemic BCG. All three patients treated with perinodular injection of BCG had complete regression of treated as well as some of untreated nodules. Treatment was unsuccessful in 9 patients. Five of them (33%) had a disease stabilisation for more than 5 months. The results of BCG immunotherapy were compared with those of chemotherapy alone. The immunotherapy patients had longer remissions and survived longer than those treated by chemotherapy. All patients had repeat skin tests with PPD after BCG but showed no significant improvement in tuberculin reactivity. Despite, their clinical condition often being improved after BCG. We conclude that BCG may be of considerable benefit to malignant melanoma patients.

Modified administration schedule of adriamycin in solid tumors.

Eighty one patients (59 females, 22 males) with advanced solid tumors were treated with Adriamycin in doses of 40 mg/m2 body surgace daily, in two days cycles, with resting periods of 3 weeks. Overall response rate was 46% (37/81). In breast cancer response rate was 56% (13/23) and in ovarian cancer 48% (13/27). In various other tumors remission was observed in soft tissue sarcomas (3/8), thyroid cancer (1/7), osteogenic sarcoma (1/4), oesophageal cancer (2/4), lung cancer (2/4), bladder cancer (1/2) and hepatoma (1/2). In breast cancer patients, 2-7 month remission duration was observed (M equal to 4.5 month) and in ovarian cancer 1.5-5 month (M equal to 3.2 month). Adriamycin was also applied intrapleurally in 31 patients with malignant pleural effusions with a low response rate (26%). This modified schedule of Adriamycin administration showed a high antitumor activity in breast and ovarian cancer and in soft tissue sarcomas. Squamous cell carcinoma of the esophagus was also sensitive to Adriamycin therapy. The very low rate of myelosuppression and oral ulceration showed the decreased toxicity of this Adriamycin administration schedule.
