    Notes: Abstract The effects and interaction of endocrine and cytotoxic adjuvant treatment on measures of cellular immunity were assessed in 41 stage I–II breast cancer patients from International Breast Cancer Study Group trials. Counts of lymphocytes and lymphocyte subsets [(T, T4, T8, B, natural killer (NK) and activated T (AT) cells] were assessed by flow cytometry immediately before adjuvant therapy at baseline and on day 1 of the 3rd cycle. Twenty-two patients received cyclophosphamide, methotrexate and 5-fluorouracil (CMF), 7 CMF and tamoxifen (TAM), and 12 TAM alone. On day 1 of the 3rd cycle the counts of total lymphocytes (P=0.003 ) and all lymphocyte subsets (P〈0.05) except AT cells were significantly lower than baseline in the CMF treatment group. There was no significant change in the CMF+TAM or in the TAM treatment group. The combination of CMF and TAM resulted in less pronounced decrease in lymphocyte and subset counts from baseline to day 1 of the 3rd cycle. It seems possible that there is an interaction between TAM with CMF that affects lymphocyte and lymphocyte subset counts during cytotoxic treatment.

    Notes: Abstract To assess the efficacy of carboplatin in patients with hormone-refractory prostate cancer in terms of response rate and palliation, the Swiss Group for Clinical Cancer Research (SAKK) conducted this phase II clinical trial (SAKK 08/91). Carboplatin 400 mg/m2 was administered i.v. every 28 days to 27 patients. The prostate-specific antigen (PSA) level was monitored and compared with the clinical response. Tumour response was evaluated according to EORTC criteria. For patients with nonmeasurable disease, response was defined as the absence of progression in any tumour localization, with no increase in PSA and a decrease of at least 2 points in the WHO pain score. Selected aspects of quality of life (QL) and use of analgesics were assessed to describe patients' experience of toxicity and palliation. Only 1 patient with measurable and 2 patients with nonmeasurable disease achieved partial remission or a response according to our criteria. However, 13 of the 27 evaluable patients had some benefit from carboplatin therapy, as indicated by an improvement in performance status, reduction of pain, and stabilization of metastases. There was no clear-cut association between clinical response and PSA level. QL data suggested that carboplatin was relatively well tolerated and confirmed the clinically documented palliation. In particular, from baseline, for at least two consecutive cycles, 7 patients reported either an improvement in pain by 1 point or more on a 4-point scale (≥33%) without an increase in analgesic intake or a decrease by 50% or more in analgesic intake without an increase in pain. With the dose and schedule used in this study, carboplatin had only limited objective activity in advanced prostate cancer, but induced palliation in about half the patients.

    Description / Table of Contents: Ziel: Analyse des Krankheitsverlaufs (krankheitsspezifisches Überleben, lokale Tumorkontrolle, Spättoxizität, Lebensqualität) nach kurativer Radiotherapie eines nichtmetastasierten Prostatakarzinoms bei älteren Patienten im Vergleich zu jüngeren. Patienten und Methodik: Aus der Datenbank wurden den 59 über 74 Jahre alten Patienten im Verhältnis 1 : 2 jüngere Patienten zugeordnet, die im gleichen Zeitraum, mit gleichem Tumorstadium, histologischem Differenzierungsgrad, PSA sowie gleicher Vorbehandlung bestrahlt worden waren. Die noch lebenden Patienten wurden schriftlich gebeten, einen validierten Fragebogen zur Lebensqualität (EORTC QLQ-C30) auszufüllen. Die mediane Beobachtungszeit für die älteren und jüngeren Patienten betrug 5,2 bzw. 4,5 Jahre. Ergebnisse: Das Fünf-Jahres-Überleben für die älteren bzw. jüngeren Patienten betrug 66% und 80%. Interkurrente Todesfälle waren im Kollektiv der Älteren häufiger. Krankheitsspezifisches Überleben (78% bzw. 82% nach fünf Jahren), Spättoxizität und Lebensqualität waren in beiden Alterskategorien gleich. Die Rate klinisch bedeutsamer lokaler Tumorprogredienz (15% bzw. 14% innerhalb von fünf Jahren) entspricht Angaben aus der Literatur nach alleiniger hormonablativer Therapie. Schlußfolgerungen: Ein altersspezifischer Unterschied des Krankheitsverlaufs inklusive Spättoxizität und Lebensqualität nach Radiotherapie wurde nicht beobachtet. Eine klinisch relevante lokale Tumorprogredienz nach Bestrahlung wie auch nach hormonablativer Behandlung ist selten. Außer in sehr frühen Stadien (T1 G1–2 M0) ist der Einsatz einer dieser beiden Behandlungen bei älteren Patienten zur Erzielung einer lebenslangen lokalen Tumorfreiheit zu empfehlen.
    Notes: Purpose: To detect a difference in outcome (disease-specific survival, local tumor progression, late toxicity, quality of life) after curative radiotherapy for localized prostate cancer in elderly as compared to younger patients. Patients and Methods: In a retrospective analysis 59 elderly patients (〉 74 years old) were matched 1 : 2 with younger patients from the data base according to tumor stage, grading, pre-treatment PSA values and year of radiotherapy. Surviving patients were contacted to fill in a validated questionnaire for quality of life measurement (EORTC QLQ-C30). Median follow-up for elderly and younger patients was 5.2 and 4.5 years, respectively. Results: Overall survival at 5 years was 66% for the elderly and 80% for younger patients. Intercurrent deaths were observed more frequently in the elderly population. There was no age-specific difference in disease-specific survival (78% vs 82%), late toxicity or quality of life. Clinically meaningful local tumor progression was observed in 15% and 14%, respectively, corresponding to data from the literature following hormonal ablation. Conclusion: There is no obvious difference in outcome including disease-specific survival, late toxicity and quality of life in elderly patients, compared to a matched younger population. A clinically meaningful local tumor progression following radiotherapy or hormonal ablation only is rare. Local radiotherapy or, alternatively, hormonal ablation is recommended to preserve local progression-free survival in elderly patients except for very early stage of disease (i. e. T1 G1–2 M0).
