[Complementary medicine for chronic and terminal illness].

Complementary methods are requested and used very often by patients suffering from chronic, incurable or terminal illness, expecting strengthened physical and mental resistance, better response to therapy with less side-effects. Unfortunately there is very limited evidence for efficacy of most complementary methods. Nevertheless proven harmless methods should be admitted without rising false hope. The most important remains however loving care.

Effect of carboplatin on response and palliation in hormone-refractory prostate cancer. Swiss Group for Clinical Cancer Research (SAKK).

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 (> or = 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.

[Complementary medicine--health policy and health care costs].

Complementary medical methods are increasingly offered by physicians as well as other members of the health services and numerous therapists and they are sought and used by a majority of the population. From the point of view of health care authorities the question of acceptance or admission of methods and offering persons is raised. Unfortunately Switzerland lacks an uniform federal curriculum for practitioners of natural cures of other therapists in complementary medicine. Therefore, in order to control the steadily increasing wild growth of complementary medical offerings, several states (Kantone) have introduced examinations for the registration of such paramedical practitioners. Whether complementary (paramedical) medicine will really reduce costs of health care remains unproven so far. According to several surveys most alternative methods are used in addition to "school medicine" (academic medicine). Health insurance companies should subject reimbursement of costs to the fulfillment of standards regarding efficacy, appropriateness and economy equal to all other medications and therapies.

Adjuvant chemotherapy in operable breast cancer: cyclophosphamide, methotrexate, and fluorouracil versus chlorambucil, methotrexate, and fluorouracil--11-year results of Swiss Group for Clinical Cancer Research trial SAKK 27/82.

PURPOSE: To compare two adjuvant combination chemotherapies, cyclophosphamide, methotrexate, and fluorouracil (CMF) and chlorambucil, methotrexate, and fluorouracil (LMF), for patients who had undergone potentially curative surgery for unilateral breast cancer, in terms of relapse, survival, and toxicity. PATIENTS AND METHODS: Selection criteria was as follows: stage pT1-3a, N+ or N-, M0, less than 72 years of age. Eligible patients were randomized to receive either CMF (cyclophosphamide 100 mg/m2 orally on days 1 to 14, methotrexate 40 mg/m2 intravenously (I.V.) on days 1 and 8, fluorouracil 600 mg/m2 I.V. on days 1 and 8) or LMF (Leukeran [Wellcome A.G., Bern, Switzerland] 5 mg/m2 orally on days 1 to 14 with the some I.V. cytostatic drugs). Follow-up examinations were performed every 3 months during the first 3 years after mastectomy, and every 6 months thereafter. RESULTS: A total of 246 patients were randomized, of whom 232 who were fully eligible and contribute to the analyses presented here. No statistically significant difference in favor of adjuvant CMF over LMF emerges after a median follow-up duration of 11.2 years, for either overall survival (P = .15) or disease-free survival (P = .14). A consistent trend suggestive of a possible relative benefit associated with CMF should be pointed out. However, CMF presents a significantly worse toxicity profile as concerns hematologic parameters as well as alopecia, nausea, and vomiting. CONCLUSION: This prospective trial has not identified a statistically significant difference in disease-free survival or overall survival between the two adjuvant regimens LMF and CMF. Although a trend in favor of CMF has been observed in premenopausal patients, this has to be weighted against its definitely more pronounced toxicity profile.

Treatment of ovarian cancer with surgery, short-course chemotherapy and whole abdominal radiation.

BACKGROUND: The primary aim was to induce a high number of pCR in early (FIGO IC, IIB + C) - and advanced (FIGO III-IV) - stage ovarian cancer with a surgery plus 4 cycles of cisplatin and melphalan (PAMP) regimen. The second objective was to prevent relapse with WAR in patients in remission after chemotherapy. PATIENTS AND METHODS: 218 eligible patients were treated after staging laparotomy with cisplatin 80 mg/sqm i.v. on day 1 and melphalan 12 mg/sqm i.v. on day 2 q 4 weeks. Response was verified by second-look laparotomy. WAR was carried out with the open field technique on a linear accelerator (daily dose: 1.3 Gy, total dose: 29.9 Gy) in patients with pathological or clinical CR or pathological PR with microscopical residual disease. RESULTS: 146/218 patients (67%, 95% CI: 61%-73%) responded to PAMP: 56 (26%) achieved pCR, 24 (11%), cCR, 56 (26%) pPR and 10 (5%) cPR (c = clinical, p = pathological). Multivariate analyses revealed that in advanced stages (92 cases in remission), the achievement of pCR was the most important factor for longer time to failure (TTF) and survival. Only 51/118 (43%) patients in remission received WAR. Early-stage patients <= 55 years were more likely to have WAR than patients older than 55 years (77% vs. 23%; p = 0.02). Advanced-stage patients with cCR were less likely to be irradiated than patients with pCR or pPR (10% vs. 51%; p = 0.003). Toxicity of PAMP was acceptable with 10% of WHO grade 4 hematologic toxicity. Acute hematological toxicity of WAR caused interruption (33%) or incompleteness (33%) of irradiation in the majority of patients. CONCLUSIONS: PAMP is an effective treatment for advanced ovarian cancer with a 67% response rate after 4 cycles. For the majority of patients in remission, WAR as a consolidation treatment was hardly feasible. For these patients new treatment modalities to consolidate remission are needed.

First-line fadrozole HCI (CGS 16949A) versus tamoxifen in postmenopausal women with advanced breast cancer. Prospective randomised trial of the Swiss Group for Clinical Cancer Research SAKK 20/88.

BACKGROUND: In a phase III randomized trial, we compared the effectiveness and tolerability of fadrozole (CGS 16949A), a non-steroidal aromatase inhibitor, to tamoxifen as first-line endocrine therapy in postmenopausal women with advanced breast cancer. PATIENTS AND METHODS: Two hundred twelve eligible patients were randomized to receive tamoxifen 20 mg daily, or fadrozole 1 mg twice daily orally until disease progression or the advent of undue toxicity. The treatments were to be discontinued upon disease progression. RESULTS: Prognostic factors were well balanced between the treatment groups, except for sites of metastatic disease. Fadrozole-treated patients had significantly more visceral, especially liver, involvement and less bone-dominant disease. Response rates for fadrozole and tamoxifen were similar, 20% and 27% (95% Confidence Limits (CL): 13%-29% and 21%-35%), respectively. Time to treatment failure was longer in patients randomized to tamoxifen (8.5 months for tamoxifen vs. 6.1 months for fadrozole), but did not reach statistical significance after adjustment for prognostic factors (P = 0.09). Fadrozole, for which a significantly lower percentage of clinically relevant toxic effects (WHO toxicity grade > or = 2) was recorded (27% vs. 13%, respectively; P = 0.009), was better tolerated than tamoxifen. Severe cardiovascular events including 3 fatalities were seen only in patients treated with tamoxifen. Eighty-two patients crossed over to tamoxifen and 66 patients to fadrozole. Crossover endocrine therapy led to response or stable disease in 64% of the patients. The overall survival times of the two treatment groups were similar. CONCLUSIONS: Fadrozole and tamoxifen showed similar efficacy as first-line treatments in postmenopausal patients with advanced breast cancer. Fadrozole was significantly better tolerated and may therefore be an appropriate alternative to tamoxifen, especially for patients predisposed to thromboembolic events.

Pamidronate for pain control in patients with malignant osteolytic bone disease: a prospective dose-effect study.

In a prospective dose-escalation study tolerability and effectiveness of repeated infusions with intravenous pamidronate were investigated. A total of 80 patients with proven malignancy and pain due to osteolytic bone disease were enrolled. Doses of 30 mg, 45 mg, 60 mg and 90 mg pamidronate, given every 4 weeks, 3 weeks or 2 weeks were tested. Thus dose intensity was increased by giving higher doses and/or by shortening the intervals. A combined palliation score on the bases of pain score (WHO), analgesic score (WHO) and improvement of performance status (SAKK/ECOG) was rated by the physician on a six-point scale. Regression analysis showed a close correlation between dose intensity and effect (Pearson's R = 0.7: P < 0.0001). A statistically significant different palliative score for patients treated with low (below 15 mg/week), medium (16-30 mg/week) and high doses (above 31 mg/week) of pamidronate was found (P = < 0.01). A dose intensity below 10 mg pamidronate/week and single doses of 30 mg had no clinically relevant benefit, whereas dose intensities of 25-45 mg/week showed a significant palliative effect. We conclude that pamidronate should be given in a close intensity of 20 mg per week or more in patients with far advanced osteolytic bone disease. Best results are obtained with high doses of 60 mg or 90 mg pamidronate. Further investigations by prospective randomized trials are needed to determine the optimal dose and schedule of pamidronate infusions.

First isolated locoregional recurrence following mastectomy for breast cancer: results of a phase III multicenter study comparing systemic treatment with observation after excision and radiation. Swiss Group for Clinical Cancer Research.

PURPOSE: We performed a randomized phase III multicenter study to compare systemic treatment versus no treatment after complete excision and radiotherapy for isolated first locoregional recurrence in patients with breast cancer. PATIENTS AND METHODS: One hundred sixty-seven good-risk patients with an estrogen receptor (ER+) positive recurrence or, in case of unknown receptor status, a disease-free interval (DFI) of greater than 12 months and < or = three recurrent tumor nodules each < or = 3 cm in diameter were entered onto the study. They were randomized to observation subsequent to local treatment or to receive tamoxifen (TAM) until disease progression. Seventy-nine percent of the patients were postmenopausal. RESULTS: The median observation period for the entire study population was 6.3 years. The median disease-free survival (DFS) duration was 26 months for observation and 82 months for TAM patients (P = .007). This was mainly due to the reduction of further local recurrences, whereas the occurrence of early distant metastases was delayed. A multivariate analysis identified DFI and treatment with TAM as significant prognostic factors for DFS. The 5-year overall survival (OS) rates were 76% and 74%, respectively (P = .77). DFI was also a prognostic factor for OS. CONCLUSION: Systemic therapy with TAM after isolated locoregional recurrence of breast cancer significantly increased 5-year DFS rates from 36% to 59% compared with observation alone and prolonged median DFS by more than 4.5 years in patients with ER+ tumors or in the case of unknown ER status with a DFI of greater than 12 months and minimal tumor burden. Treatment with TAM currently has no significant impact on OS, but the median survival duration of the study population has not yet been reached.

[Risk-benefit considerations in the drug therapy of chronic tumor-related pain].

Cost and risk assessment in medicine requires evaluation of objective and subjective parameters. Objectively correct medicamentous treatment of chronic pain is cost-effective, above all by reducing expensive hospitalization. The greatest benefit for the patient comes from improved quality of life and increased independence and mobility. Side effects of drugs are inevitable but can be controlled successfully in most instances.

Oral ondansetron in the prophylaxis of nausea and vomiting induced by cyclophosphamide, methotrexate and 5-fluorouracil (CMF) in women with breast cancer. Results of a prospective, randomized, double-blind, placebo-controlled study.

BACKGROUND: The combination of cyclophosphamide, methotrexate and 5-fluorouracil (CMF) is a widely used chemotherapy regimen in breast cancer patients. However, the control of nausea and vomiting induced by oral CMF is a rarely examined problem. Therefore we felt a randomized, placebo controlled study justified in order to improve currently available antiemetic therapy. SUBJECTS AND METHODS: In a randomised double-blind trial ondansetron given orally, 8 mg three times a day for 15 days, was compared with placebo in 82 breast cancer patients receiving chemotherapy with CMF (cyclophosphamide 100 mg/m2 orally days 1-14, methotrexate 40 mg/m2 i.v. days 1 and 8 and 5-fluorouracil 600 mg/m2 i.v. days 1 and 8). The patients recorded nausea and the number of vomits and retches daily on diary cards. Forty-two patients received ondansetron and 40 received placebo. RESULTS: Significantly more patients who received ondansetron experienced neither vomiting nor retching (emesis) compared to those receiving placebo over a 15 day treatment period (60% vs. 35%, p = 0.027). The difference, with 95% confidence limits, was estimated at 25 (4.45%). Furthermore, there was a trend in favour of ondansetron in the control of nausea. Ondansetron was well tolerated, with 25 patients (59%) reporting at least 1 adverse event compared to 18 patients (45%) receiving placebo (p = 0.191). CONCLUSION: The results indicate that ondansetron given orally for 15 days is safe and effective in the control of emesis induced by CMF. It is however too early to recommend ondansetron as standard antiemetic therapy for oral CMF, as the treatment of nausea and vomiting in this setting has not been studied thoroughly enough.

Swiss adjuvant trials in women with node-negative breast cancer. OSAKO.

Women with node-negative breast cancer have a 30% chance of relapse 5 years after mastectomy. If it is possible to prevent or defer recurrent disease with adjuvant systemic therapy, node-negative patients, with their low tumor burden, should theoretically benefit most from such treatment. In 1974 we started a randomized adjuvant trial in eastern Switzerland, using a subjectively less toxic regimen [chlorambucil, methotrexate, and fluorouracil (LMF)]. Two hundred fifty-four patients were randomly assigned after standardized modified radical mastectomy to observation only or to treatment with oral LMF for 6 months followed by BCG skin scarifications monthly for up to 2 years. While we find no significant statistical difference between the control group and the treated group in terms of relapse-free survival, there is a strong and consistent trend toward prolongation of overall survival within the treated group.

[Why do cancer patients use alternative medicine?].

160 patients (53.3%) replied to an anonymous questionnaire distributed to 300 consecutive patients of our Outpatient Oncology Clinic. 83 patients (53%) mentioned some experience of one or more alternative methods of cancer treatment. Most often cited were various herbal teas (35 instances), beetroot juice (16), Vogel plant extracts (15), laying-on of hands (14), homeopathic medicine (13), the mistletoe extract Iscador (13), magnetopathy (12), various diets (10), acupuncture (10) and psychological methods (9). Resort to alternative methods of treatment correlated significantly with lower age (51.5 years vs 59.8 years, p = 0.001). The reasons for using alternative medicine were the desire to do everything possible to regain health (49), to use one's psychological forces as well (35), reports of successful cancer cures (28), desire for a holistic approach (23), hope of "softer" medicine with less severe side effects (18) and, in 7 cases only, disappointment with conventional university medicine. The major source of information was relatives and friends, not the mass media. The physician should be aware of the locally available alternative medicine options and be able to advise his patients accordingly. He should also recognize and give due consideration to the patient's underlying desire for better control of his disease and a more holistic approach to care.

[Peripheral spontaneous remission of hairy cell leukemia following transfusion-associated hepatitis C].

In a 59-year-old patient presenting in October 1981 with pancytopenia, hairy cell leukemia was diagnosed. Splenectomy, followed by treatments with oncovin, lithium, and prednisone were essentially without effect. Up to July 1984 the patient had been regularly transfused with a total of 62 unit. In June 1984 he acquired a transfusion associated hepatitis C which followed a chronic course and resulted in biopsy proven cirrhosis in 1989. The patient became independent of transfusions in July 1984. Repeated blood counts have shown a complete hematologic remission which has now lasted nearly 6 years, whereas focal leukemic infiltrates have persisted in the bone marrow. The patient has tolerated 20 courses of erythropheresis performed because of biopsy proven severe hepatic siderosis without a fall in hemoglobin. It is suggested that the spontaneous long-lasting hematologic remission of hairy cell leukemia is due to endogenous interferon produced in the course of chronic hepatitis C. Low serum levels of interferon-alpha and -gamma were detected.
