    Description / Table of Contents: Résumé Quarante-trois malades qui présentaient un cancer du sein avancé (15 répondant au stade IIIA et 28 au stade IIIB) ont été traitées par chimiothérapie et chez 38 d'entre elles par hormonothérapie associée pour obtenir une involution tumorale avant de procéder au traitement local. Lorsque la réponse à ce traitement fut complété (CR) la radiothérapie fut associée à la chimiothérapie. Quand la réponse fut incomplète (PR = réponse partielle) ou négative (NC = pas de changement) l'intervention chirurgicale fut pratiquée et suivie d'une irradiation locale. Chez toutes les malades la chimiothérapie fut ensuite poursuivie pendant 6 mois. La chimiothérapie consista en l'administration de cyclophosphamide 500 mg/m2; de doxorubicine 30 mg/m2 I.V. au jour 1; de tamoxifen: 40 mg/m2 P.O. les jours 2–6; de premarine 0.625 mg P.O. Q 12×3h à partir du 71ème jour, de méthotrexate: 300 mg/m2 I.V. suivi après 1 heure par du 5-fluorouracil 500 mg/m2 par voie I.V. au jour 8 et de leucovirine 10 mg/m2 P.O. Q 6h×6 commençant 24 h après le méthotrexate. Quarante-deux malades sur 43 purent être soumises à l'étude en ce qui concerne la réponse au traitement, le temps d'évolution et la survie. Le taux de la réponse à l'action des agents chimiques fut le suivant: involution complète, 50%; involution partielle, 40%; inefficacité 10%. Le nombre médian de cycles de chimiothérapie pour aboutir à ces résultats fut respectivement de 5,4 et 4. Dix-huit malades qui bénéficièrent d'une involution clinique tumorale complète furent soumises à des biopsies multiples (16) ou à une mastectomie (2). Quatorze malades (70%) ne présentaient aucune trace tumorale à l'examen histologique. Trente malades sur 42 qui ont été soumises au traitement combiné complet ne présentent à ce jour aucun signe d'évolution du processus tumoral. Les malades du stade IIIA n'ont pas montré de récidive. En revanche 7 cas de stade IIIB ont rechuté, 6 d'entre eux montrant des lésions inflammatoires à l'histologie. Pour chaque stade la survie médiane et le temps d'évolution n'ont pu être apprécié au cours de cette étude.
    Abstract: Resumen Cuarenta y tres pacientes con cáncer mamario localmente avanzado, 15 en estado IIIA y 28 en estado IIIB, recibieron quimioterapia primaria de inducción, incluyendo sincronización hormonal en 38 pacientes, hasta el logro de una respuesta clínica objetiva máxima antes de proceder con terapia local. Las pacientes que lograron una respuesta completa desde el punto de vista histológico (múltiples biopsias sobre el lugar de la lesión original) recibieron radioterapia, mientras las pacientes con enfermedad residual (respuesta parcial o ninguna respuesta) fueron sometidas a cirugía de “debultamiento” antes de iniciar la radioterapia; en la totalidad de las pacientes se administraron 6 meses adicionales de quimioterapia. La quimioterapia consistió en ciclofosfamida 500 mg/m2 y doxorubicina 30 mg/m2 I.V. el día 1; tamoxifén 40 mg/m2 PO en los días 2–6; premarina 0.625 mg PO q 12 horas × 3, comenzando en el día 7; metotrexato (mtx) 300 mg/m2 I.V. seguido una hora después de 5-fluoruracilo 500 mg/m2 I.V. el día 8 y leucovorin 10 mg/m2 PO q 6 horas × 6 comenzando 24 horas después del mtx. Cuarenta y dos pacientes son evaluables en relación a la respuesta lograda, al tiempo de progresión y a la supervivencia. La tasa de respuesta objetiva a la quimioterapia fue de 90% con 50% de respuesta completa, 40% de respuesta parcial y 10% de ninguna respuesta. El número promedio de ciclos de quimioterapia necesarios para lograr respuesta completa, respuesta parcial o ninguna respuesta fue de 5, 4, y 4 respectivamente. Dieciocho pacientes con respuesta completa a la quimioterapia fueron evaluadas mediante biopias múltiples (16 pacientes) o mastecomía (2 pacientes). Catorce (70%) demostraron respuesta completa desde el punto de vista histológico. Treinta pacientes han completado terapia combinada hasta el momento y todas se han convertido a un estado libre de enfermedad. Siete pacientes en estado IIIB han presentado recurrencia, 6 de ellas con histología de enfermedad tumoral inflamatoria. Ninguna paciente en estado IIIA ha presentado recurrencia. No se ha llegado todavía a determinar la supervivencia media ni el tiempo de progresión para ninguno de los estados.
    Notes: Abstract Forty-three patients with locally advanced breast cancer, 15 with stage IIIA and 28 with stage IIIB, received primary induction chemotherapy, including hormonal synchronization in 38 patients, to a maximum objective clinical response before proceeding to local therapy. Patients achieving a pathological complete response received radiation therapy, while patients with residual disease, partial response (PR), or no change (NC) status received debulking surgery prior to radiation therapy; in all patients, 6 additional months of chemotherapy were administered. Chemotherapy consisted of cyclophosphamide 500 mg/m2 and doxorubicin 30 mg/m2 intravenously day 1; tamoxifen 40 mg/m2 orally days 2–6; premarin 0.625 mg orally every 12 hours 3 times beginning on day 7; methotrexate (mtx) 300 mg/m2 intravenously followed in 1 hour by 5-fluorouracil 500 mg/m2 intravenously day 8, and leucovorin 10 mg/m2 orally every 6 hours 6 times beginning 24 hours after mtx. Forty-two patients are evaluable with respect to response, time to progression, and survival. Objective response rate to chemotherapy was 90% with 50% CR, 40% PR, and 10% NC. Median number of cycles of chemotherapy to achieve a CR, PR, or NC was 5, 4, and 4 respectively. Eighteen patients with a CR to chemotherapy were assessed by multiple biopsies (16 patients) or mastectomy (2 patients). Fourteen patients (70%) were proven to be pathological complete responders. Thirty patients have completed combined therapy thus far and all have been rendered disease free. Seven stage IIIB patients have relapsed, 6 of them having inflammatory histological findings. No stage IIIA patients have relapsed. Median survival and time to progression have not been reached for either stage.

    Notes: [Auszug] We have investigated the physiological mechanisms causing satiety by studying sham feeding in rats with chronic gastric fistulas. We report evidence that the polypeptide hormone cholecystokinin (CCK), which is released when food enters the small intestine5, may be a satiety signal in the rat. All ...

    Notes: Summary Combination chemotherapy regimens have produced a pathological complete response rate of only 1%–25% in patients with advanced ovarian cancer. Patients with small-volume residual disease after treatment are refractory to further systemic therapy, and most eventually die of their disease. Intraperitoneal (i.p.) chemotherapy, particularly with adriamycin or cisplatin has shown promise in these patients. However, the dose-limiting painful peritonitis associated with i.p. adriamycin makes this regimen potentially too toxic for many patients. Aclacinomycin A, another anthracycline antibiotic, has been found to have activity against a wide variety of murine tumors and human xenografts. It has also demonstrated clinical efficacy in phase I and II trials against refractory ovarian cancer and has less pronounced vesicant properties than adriamycin, making it an ideal candidate for i.p. use in ovarian cancer patients. In vitro clonogenic assays utilizing a battery of adriamycin-sensitive and-resistant human ovarian carcinoma cell lines have shown that aclacinomycin a is more cytotoxic than adriamycin in all cell lines tested. In addition, aclacinomycin A was found to prolong survival in a nude mouse xenograft of i.p. human ovarian cancer. These results have provided the experimental rationale for an ongoing clinical trial of i.p. aclacinomycin in refractory ovarian cancer patients at the Medicine Branch, NCI.

    Notes: [Auszug] ...For centuries, hepatitis has exacted a devastating worldwide toll, not only from the ravages of the disease itself, but in the later development of cirrhosis of the liver and the nearly always fatal primary liver cancer. Now, as the new millennium begins, that devastation is abating. Thirty ...

    Notes: Summary The enzyme adenosine deaminase has an essential role in lymphocyte metabolism. To examine the in vivo effects of inhibition of this enzyme healthy BDF 1 mice were injected intraperitoneally with 2′-deoxycoformycin, a stoichiometric tight-binding inhibitor of adenosine deaminase. Of the treated animals, 20% died of overwhelming infection, and histopathological examination of these, and surviving animals sacrificed 10 days following treatment indicated a selective toxicity to lymphoid cells. No toxicity to tissues other than the lymphoid system was observed, which is consistent with the hypothesis that 2′-deoxycoformycin offers a new and selective approach to the treatment of lymphoid malignancies.

    Notes: Abstract Peritoneoscopy is a valuable nonsurgical procedure for evaluating patients with malignant disease. Directed biopsies of suspected tumor masses may be obtained, and peritoneoscopy can frequently obviate the need for laparotomy. Although the complication rate is low, the radiologist must be aware of potential problems. Radiologists may participate not only in the diagnosis and localization of these complications but also in their therapy by interventional techniques. The radiographic findings in four patients with complications of peritoneoscopy are presented.

    Notes: Summary Five compounds which were identified as potential new anticancer drugs inin vitro screening with the human tumor colony forming assay were selected for further evaluation usingin vitro andin vivo models of human ovarian cancer. Three of five compounds were found to inhibitin vitro colony formation of ovarian cancer cell lines derived from both untreated and combination chemotherapy refractory patients. One compound was also found to prolong survival in a human ovarian carcinoma xenograft model system. This compound, chloroquinoxaline sulfonamide, was selected for development and has shown preliminary indication of activity in phase I clinical testing.

    Notes: Abstract Tricyclic nucleoside 5′-phosphate (TCN-P) was evaluated in two models of human ovarian cancer. TCN-P reduced both colony number and volume in clonogenic assays employing human ovarian cancer cell lines. TCN-P cytotoxicity depended on the concentration, exposure duration and cell line studied, but not on cell line plating efficiency or growth rate in soft agarose. Comparison of experimental IC50 concentrations for 1 hour or continuous TCN-P exposure with reported clinically relevant concentrations suggests that therapeutic TCN-P levels are more likely to be achieved by continuous infusions. Cell lines and sublines with resistance to several standard chemotherapeutic agents acquired both in vivo and in vitro were at most 2.6-fold cross-resistant to TCN-P with 1 hour drug exposure. Cross-resistance was not evident with continuous TCN-P exposure. Intermittent bolus TCN-P (100 mg/kg/d × 5) was ineffective in an in vivo xenograft model of human ovarian cancer. These data suggest that TCN-P is most likely to be clinically effective against ovarian cancer, and may be non-cross-resistant with several standard agents, if administered by continuous infusion. Preclinical evaluation of new agents, such as TCN-P, in these experimental models may provide information useful in subsequent clinical trials.
