    Description / Table of Contents: Résumé Cet article constitue un rapport préliminaire provenant du Groupe Oncologique du Sud-Ouest des Etats-Unis. Il concerne les effets obtenus par la chimiothérapie associée à l'exérèse du cancer du sein qui s'accompagne d'un envahissement des ganglions axillaires. L'étude est randomisée en fonction du paramètre “récepteur oestrogénique”. Les malades qui appartiennent au groupe “oestrogène récepteur négatif” sont soumis pendant 1 an ou 2 ans à une chimiothérapie CMFVP (cyclophosphamide, methotrexate, 5-FU, vincristine, prédnisone). Le groupe “oestrogène récepteur positif” est soumis à la même chimiothérapie pendant un an et/ou à un traitement hormonal. 1. Les malades du groupe “oestrogène récepteur positif” présentent une récidive plus tardive que celle des malades qui appartiennent au groupe “oestrogène récepteur négatif (p=0.004). 2. Il n'y a pas de différence significative en ce qui concerne ce fait pour les malades du groupe “oestrogène récepteur négatif qui sont traités un an ou deux ans par le CMFVP. 3. Les données pour les malades du groupe “oestrogène récepteur positif” sont trop récentes pour apprécier avec précision la durée de la survie totale ou celle de l'intervalle libre entre le traitement et la récidive. 4. La toxicité du traitement chimiothérapique est acceptable dès lors que le traitement est bien conduit sous une surveillance effectuée à intervalles réguliers et fréquents qui permet de dépister les signes avant-coureurs de la toxicité.
    Abstract: Resumen Este es un informe preliminar del Southwest Oncology Group de los Estados Unidos, grupo en el cual la terapia fue realizada en forma aleatorizada de acuerdo a los datos sobre receptores de estrógeno. Los pacientes con receptores de estrógeno negativos recibieron 1 o 2 años de CMFVP (ciclofosfamida, metotrexato, 5-fluorouracil, vincristina, y prednisona). Los pacientes con receptores de estrógeno positivos recibieron CMFVP por un año y/o terapia hormonal. 1. Los pacientes con receptores de estrógeno positivos presentaron un intervalo libre de enfermedad significativamente más largo que el de los pacientes con receptores de estrógeno negativos (p=0.004). 2. No se encontre una diferencia significativa en el intervalo libre de enfermedad entre los pacientes con receptores de estrógeno negativos que recibieron CMFVP por uno o por dos años. 3. Los datos sobre los pacientes con ER positivo son demasiado preliminares para poder informar sobre el estado libre de enfermedad o la supervivencia. 4. La toxicidad es aceptable en gracia a la monitoría mediante controles y exámenes frecuentes, lo cual resulta en una baja incidencia de toxicidad que pueda hacer peligrar la vida del paciente.
    Notes: Abstract This is a preliminary report of the Southwest Oncology Group in which therapy is randomized by estrogen receptor (ER) data. Estrogen receptor-negative patients receive either 1 or 2 years of cyclophosphamide, methotrexate, 5-fluorouracil, vincristine, and prednisone (CMFVP). The ER-positive group receive CMFVP for 1 year and/or hormonal therapy. The findings to date include: (a) Estrogen receptor-positive patients have a significantly longer disease-free interval compared to ER-negative patients (p =0.004); (b) there is no significant difference in diseasefree interval for ER-negative patients who receive either 1 or 2 years of CMFVP; (c) the data for ER-positive patients is too preliminary to report for disease-free or total survival; and (d) toxicity is acceptable because of frequent monitoring and examinations which result in the low percentage of life-threatening toxicity.

    Notes: Summary One hundred and eight patients with non-small cell lung cancer were treated in a Phase II trial with MGBG at a dose of 600 mg/m2 i.v. weekly. Partial responses were noted in 3/43 patients with adenocarcinoma and 1/40 with squamous cell carcinoma. No responses were noted in 24 patients with large cell carcinoma. Overall, the drug was reasonably well-tolerated. At this dosage and schedule, MGBG has no substantial antitumor activity for patients with non-small cell lung cancer.

    Notes: Summary The Southwest Oncology Group has evaluated methyl-GAG on a weekly schedule among patients with metastatic breast cancer. Among 72 fully and partial evaluable patients, one complete and four partial responses were seen. Toxicity was similar to other trials with this compound except for thrombocytopenia which was more frequent and severe and probably related to tumor infiltrating marrow. In addition, one patient experienced recall dermatitis following methyl-GAG. This toxicity has not been previously reported with this compound. Methyl-GAG has minimal activity at this dose and schedule among heavily pretreated patients with breast cancer.

    Notes: Summary Thirty-one evaluable adults with recurrent astrocytomas were treated with Cisplatin 35 Mg/ M2 I.V. daily for three days every 3–4 weeks. All patients had previously been irradiated and most had previously received chemotherapy. Approximately half had poor performance status. Two patients experienced complete remissions and two additional patients experienced partial remissions. Three patients stabilized. Gastrointestinal toxicity was generally mild. Further studies are planned of Cisplatin in combination with other agents.

    Notes: Abstract This report describes a symbiotic interaction between a hospital tumor registry and the physicians in a medical school department of otolaryngology. The tumor registry is responsible for collecting central registry data, entering both central registry and department-specific data, performing routine data maintenance functions, and tracking the patients over time. The departmental physicians collect site-specific data and, after entry into a computer-based data base management system, can access the information without intermediaries and at their convenience. The result is a comprehensive information resource for head and neck cancer. The development of a medical subspeciality information system, as a satellite to the central registry mechanism, is noteworthy in its low cost, frequent physican use, better patient tracking, improved patient care, and increased clinical relevance of registry activites. A subtle but pervasive benefit is the increased sense of mission experienced by all concerned.

    Notes: Summary The Southwest Oncology Group in a prospective randomized study compared one year of adjuvant combination chemotherapy with continuous CVFVP (cyclophosphamide, methotrexate, 5-fluorouracil, vincristine, and prednisone) to two years of intermittent L-phenylalanine mustard (L-PAM) in women with operable breast cancer with histologically positive axillary lymph nodes. In fully and partially evaluable patients with a 68-month median follow-up, treatment failures have occurred in 27% of 172 receiving CMFVP and 47% of 186 women given L-PAM (p = 0.002). The advantage for women receiving CMFVP was seen for all subsets regardless of menopausal status except among women who were premenopausal and had 1–3 positive nodes. Based on this study, a second study was implemented using both the estrogenreceptor (ER) content of the primary tumor and axillary nodal status to select therapy.

    Notes: Summary The Southwest Oncology Group has evaluated methyl-GAG on a weekly schedule among patients with lymphoma and Hodgkin's disease. Among 56 fully and partially evaluable patients responses were seen in 3 of 10 patients with Hodgkin's disease and 11 of 46 patients with lymphoma. Toxicity was acceptable. Methyl-GAG has significant antitumor activity among this group of heavily pretreated patients. Additional trials of methyl-GAG in combination with other agents are underway.

    Notes: Summary Mitoxantrone, an anthracenedione derivative, was administered by members of the Southwest Oncology Group to thirty patients with metastatic malignant melanoma. The drug was administered as an intravenous infusion over 30 min at a starting dose of 12 mg/m2 and repeated every three weeks. Myelosuppression was the major toxicity. As administered, mitoxantrone is not an effective agent in the treatment of malignant melanoma.
