Opinions concerning euthanasia, life-sustaining treatment and acceleration of death: results of an Italian Association of Medical Oncology (AIOM) survey.

BACKGROUND: Advance directives, acceleration of death, euthanasia and 'life-sustaining treatment' have sparked much heated debate among the media, the public, doctors and political leaders. We evaluate the personal opinions of Italian Association of Medical Oncology (AIOM) members. PATIENTS AND METHODS: A 30-item questionnaire was developed and delivered to all 1,832 AIOM members. RESULTS: Six-hundred and eighty-five (37%) oncologists completed and returned the questionnaires. Sixty-three per cent felt culturally and psychologically prepared to face these issues. Fifty-four per cent believed that what had been decided while the patient enjoyed good health is no longer applicable in an advanced state of terminal illness. Thirty-nine per cent believed that doctors should abide by these directives, while 49% believed that this should be discussed on a case-by-case basis. Fourteen per cent of oncologists were favourable towards euthanasia and 42% only in particular circumstances. Fifty-six per cent had received at least one request for accelerating death: 15% consented, 50% discussed it with the patient and 31% refused. CONCLUSION: Advance directives, euthanasia, accelerated death and life-sustaining treatment represent considerable challenges for Italian oncologists. Although prepared to face these issues, AIOM members ask for a debate within the medical world and for a shared judicial regulation.

Phase III randomized study of fluorouracil, epirubicin, and cyclophosphamide v fluorouracil, doxorubicin, and cyclophosphamide in advanced breast cancer: an Italian multicentre trial.

From February 1983 to January 1985, 497 patients with advanced breast cancer were randomly allocated to receive either epirubicin or doxorubicin in the following combination chemotherapy regimen: fluorouracil (5-FU) 500 mg/m2 intravenous (IV) on days 1 and 8; epirubicin or doxorubicin 50 mg/m2 IV on day 1; cyclophosphamide 500 mg/m2 IV on day 1 (FEC or FAC). Cycles were repeated every 21 days until progression or to cumulative doses of 700 mg/m2 for epirubicin and 550 mg/m2 for doxorubicin. Dose reductions were applied according to the standard criteria. Activity was evaluated in 443 patients (222 in the FEC arm and 221 in the FAC arm). The two experimental groups were comparable in age, performance status, menopausal status, histology, previous treatments, and site of the disease. The overall response rate (complete response and partial response [CR + PR]) was not significantly different: 53.6% for FEC and 56.5% for FAC. The median time to progression was 273 days for FEC and 314 days for FAC; the median survival time was 591 and 613 days, respectively. Leukopenia, anemia, nausea, and vomiting were significantly lower in patients treated with FEC. As for cardiotoxicity, four cases of congestive heart failure (CHF) were recorded among patients treated with FAC while only one was observed in the FEC group. These results indicate that epirubicin in a combination chemotherapy regimen is as active as doxorubicin and is significantly less toxic.

Cardiac toxicity of high-dose chemotherapy.

Cardiac toxicity is an uncommon but potentially serious complication of high-dose (HD) chemotherapy and little is known about incidence, severity and underlying mechanisms. We have systematically reviewed the literature of the last 30 years to summarize and appraise the published evidence on cardiac toxicity associated with HD chemotherapy. HD cyclophosphamide-containing regimens have been most commonly associated with cardiac toxicity, with a progressively decreasing incidence over time. Dosage, application regimens and coadministration of other chemotherapeutic agents emerged as risk factors. While cardiac toxicity has been rarely associated with other cytotoxic drugs, an unexpected incidence of severe cardiotoxicity resulted from reduced-intensity conditioning regimens containing melphalan and fludarabine. Predictive value of cardiologic examination of patients is limited, and patients with a slight depression of cardiac performance could tolerate HD chemotherapy. Clinical examination, resting electrocardiography and dosage adjustment in overweight patients remain the mainstay of prevention, with bidimensional echocardiography (2D echo) for patients with a history of anthracycline exposure. Strategies to decrease the long-term negative impact of anthracycline administration on cardiac performance are being investigated. New 2D echo-based techniques and circulating markers of cardiac function hold promise for allowing identification of patients at high risk for and early diagnosis of cardiac toxicity.

Combination chemotherapy with cmf (cyclophosphamide, methotrexate, 5-Fluorouracil) versus cnf (mitoxantrone, 5-Fluorouracil, cyclophosphamide) in advanced breast-cancer - a multicenter randomized study.

A multicentric randomized study was conducted to compare the CNF regimen (cyclophosphamide at 600 mg/m2/iv, mitoxantrone at 10 mg/m2/iv, 5-fluorouracil at 600 mg/m2/iv) with the CMF regimen (methotrexate at 40 mg/m2/iv instead of mitoxantrone) administered every 3 weeks to previously untreated locally advanced or metastatic breast cancer patients. In 119 patients evaluable for therapeutic response, complete plus partial response rate was 44% for CNF and 29% for CMF (p>0.05; 95% C.I.: CNF=32%-56%, CMF=18%-40%). No statistically significant difference regarding time to progression, over survival or response to second-line chemotherapy with Epidoxorubicin was observed between the two regimens. Both regimens were well tolerated, but the percent of alopecia and leucopenia was significantly higher in the CNF patient group (31% versus 5% and 18% versus 0%, respectively; p<0.01). In conclusion, CNF was demonstrated to be slightly more toxic but more effective as compared to CMF (global response: 44% versus 29%, respectively). These findings should be taken into consideration when planning future studies of adjuvant chemotherapy.

Pharmacokinetics and tumor concentration of intraarterial and intravenous cisplatin in patients with head and neck squamous cancer.

Tumor-tissue platinum levels and major pharmacokinetic parameters were determined in 11 patients with head and neck squamous cancer (HNSC) who were given cisplatin (50 mg/m2 daily x 2 days) and 5-fluorouracil (5-FU; 1000 mg/m2, continuous infusion x 5 days) either i.a. or i.v. The plasma peak platinum concentrations (cmax) and the areas under the curve for total platinum concentration versus time (AUC) during i.a. infusions were lower than the i.v. cmax (mean, 1.92 +/- 0.28 and 4.08 +/- 2.80 mg/l, for i.a. and i.v. infusions, respectively) and AUC values (mean, 22.55 +/- 4.96 and 40.66 +/- 10.71 mg h-1 l-1 for i.a. and i.v. treatment, respectively), suggesting a first-passage extraction of the drug by the tumor mass during i.a. infusion. However, no statistically significant difference was found in platinum tumor concentrations after i.a. administration versus i.v. infusion. The lack of a difference in tumor platinum concentrations between the i.a. and the i.v. administration routes might be explained either by a relatively high blood supply to the tumor area, enabling efflux of the surplus free platinum from the tissue, or by the delay between drug infusion and biopsy. After three cycles of i.a. treatment good tumor remission was obtained with minimal local toxicity. Larger clinical studies testing the advantages of the i.a. administration route over i.v. infusion appear to be necessary.

Oral ondansetron (GR38032F) for the control of acute and delayed cyclophosphamide-induced emesis.

The efficacy of the serotonin antagonist ondansetron (GR38032F, Glaxo) was evaluated in the prevention of nausea and vomiting induced by combinations containing cyclophosphamide (CTX) greater than or equal to 600 mg/m2 IV day. At their first treatment course, 55 patients (10 males, 45 females) median age 55 years (range 31-76) were given ondansetron 8 mg orally tds for a minimum of 3 to a maximum of 5 days. 54 patients were evaluable. Complete and major control of acute (day 1) emesis was observed in 94.5% of patients and acute nausea was graded as absent or mild in 83.3% of cases. Complete and major control of emesis improved on subsequent study days from 96.1% on study day 2 to 100% on study day 5. Side effects were mild. Ondansetron is a safe and effective antiemetic drug.

Response and toxicity of cisplatin and 120-h 5-fluorouracil infusion in pretreated and untreated patients with advanced epidermoid cancer of the head and neck.

Eighty-two patients with advanced or recurrent squamous cell carcinoma of the head and neck were treated with bolus cisplatin and 120-h infusion of 5-fluorouracil. Among 49 pretreated patients, there were 9 complete and 12 partial responses, for an overall response rate of 43% and a median estimated survival of 8 months. Hematologic toxicity in this group was relevant, with 4 early deaths and 30% of cases with moderate to severe leukopenia; mucosal and renal toxicities were also important. Among 33 patients with no prior therapy, there were 8 complete and 17 partial responses, for an overall response rate of 76%. Fifteen of the 25 responding patients received subsequent locoregional treatment. The median estimated survival in this group was 29 months. Hematologic, mucosal, and renal toxicities were only mild to moderate. Episodes of possible 5-fluorouracil-related cardiotoxicity were recorded in both pretreated and untreated patients. Twelve of 41 partial responses observed after the second cycle of therapy were converted to complete responses with a third (8 cases) and also a fourth (4 cases) course. This study confirmed that cisplatin plus 5-fluorouracil is a first-choice combination in previously untreated patients. Definitive evidence that chemotherapy can favorable influence survival awaits confirmation by randomized trials, using a control arm with conventional locoregional treatment. In previously treated patients with recurrent disease, less intensive regimens not requiring hospitalization seem more useful for the quality of life.

FAM2 regimen in disseminated gastric cancer.

Forty-four previously untreated patients with advanced inoperable and/or disseminated gastric carcinoma were given an i.v. combination (FAM2) chemotherapy of 5-fluorouracil, 400 mg/m2 on days 1, 2 and 3, and 21, 22 and 23; adriamycin, 40 mg/m2 on days 2 and 22; and mitomycin C, 10 mg/m2 on day 1, with a recycle on day 42 (1 cycle = 41 days). Forty patients have completed 2 cycles and are evaluable (median number of cycles 5; range 3 to 8): 26 of these achieved a partial remission, with a response rate of 65%; 4 (10%) gained a stable situation for 3 to 6 months, and 10 (25%) showed progression of disease. Median duration of partial remissions was 10 months, and median survival was 15 months for responders and 5 months for nonresponders. A fall in WBC (less than 2500/microliter) occurred in 7% and of platelets (less than 80,000/microliter) in 4.5%. Total alopecia occurred in 20 of 40 patients and nausea and or weakness were common findings. No drug-related infection, bleeding or death was observed. Patients with advanced gastric carcinoma can derive useful palliation from FAM2 chemotherapy.

[Toxicity of high-dose bleomycin administered by continuous infusion]. / Tossicità della bleomicina somministrata in infusione continua ad alte dosi.

Fifteen patients with nonseminomatous testicular cancer underwent multidrug treatment which included cis platinum, Velban and bleomycin. The latter drug was administered in monthly 5 day courses of 100 mg/m2. No impairment of antitumor effect resulted since 12 of 15 patients had remissions (10 complete and 2 partial). Pulmonary toxicity was practically abolished: a median dose of 675 mg per patient (range 450 to 1050) was followed by normal lung X-ray and normal or near normal functional parameters after completing treatment. Median arterial oxygen pressure was 78 mm Hg (range 62 to 89), and median Tiffeneau index was 84 (range 64 to 87). Only 2 of 15 patients had skin marks from bleomycin toxicity at the end of treatment, so that cutaneous toxicity was also very low. Oral mucosa reversible damage was prominent in 2 patients. On the contrary, alopecia was a common finding.

High-dose medroxyprogesterone in disseminated breast cancer. Correlation between bioavailability and clinical response.

Clinical response to high-dose medroxyprogesterone (MPA), administered following three different routes of administration (i.m., p.o. + i.m., p.o.) and monitoring drug plasma levels, was evaluated in pretreated advanced breast cancer patients. Fifty-eight of 68 eligible patients were considered evaluable for response. Age ranged between 36 years and 82 years. Fifty-six of 58 evaluable patients were postmenopausal. An overall remission rate of 48% was achieved with i.m. MPA, 50% with combined (i.m. + p.o.) modalities; only a 19% remission rate was recorded in the p.o. group. Response rate and MPA plasma concentrations were correlated, and a drug level of 80 ng/ml, by means of a GLC method, seems to identify a subset of patients with high probability of response. Only mild toxic effects were recorded.

The value and present indications of staging laparotomy in Hodgkin's disease.

From December 1971 to December 1976 224 patients with Hodgkin's disease underwent diagnostic laparotomy and splenectomy under a multidisciplinary protocol of treatment. In 149/224 (66.5%) the clinical stage of the disease was confirmed, whereas in 75/224 (33.5%) it was modified after surgery. In 7.6% of the patients (17/224) there were postoperative complications. One patient died of myocardial infarction. The rate of complications in the last 100 cases was 5%. Preoperative patient selection, excluding those definitely in stage IV, is of relevance, and it can be done by iliac crest biopsy and laparoscopy. Although a better exploitation of some diagnostic procedures (lymphangiography, laparoscopy) and the expanding use of chemotherapy may reduce in the future the need for staging laparotomy and splenectomy, diagnostic laparotomy is still indicated for the selection and preparation of patients for radiation therapy in stages I, II and III.

Cis-dichlorodiammineplatinum (II), VP 16-213, and prednisone (DVP regimen) in the treatment of pretreated advanced malignant lymphomas.

Eighteen evaluable patients with advanced malignant lymphoma were treated with a combination of cis-dichlorodiammineplatinum (II) (50 mg/m2 i.v. on day 1), VP 16-213 (100 mg/m2 i.v. on days 1, 3, 5), and prednisone (50 mg/m2 per os on days 1-5), recycling every 2 weeks. All patients were previously pretreated. There were 3 complete remissions (patients with Hodgkin's disease), and 4 partial remission (2 patients with Hodgkin's and 2 with non-Hodgkin's lymphoma), for a median duration of 8 weeks. In addition, 2 minor responses (patients with Hodgkin's disease) were observed. Vomiting and myelosuppression were the most prominent toxic effects. In most heavily pretreated patients, myelosuppression was moderate to severe: in these patients and in patients with bone marrow involvement, a schedule interval of 3 weeks should be more appropriate. Nephrotoxicity was minimal. This combination chemotherapy showed some activity in the management of advanced malignant lymphomas; further studies in this area are justified.

Tamoxifen in disseminated breast cancer.

86 postmenopausal women with disseminated breast cancer have been treated orally with 30 mg of Tamoxifen per day (ICI 46474, Nolvadex) for periods of 2 months or more. The overall responders were 28/86 (32.5%) with a median remission duration of 9 months. In 30 patients already shown to be resistant to cytotoxic chemotherapy. Tamoxifen was used as first hormonal agent; the remission rate in this group was 12/30 (40%), while it was 28.5% (16/56) in the others who had already received different hormonal treatments. In 6 early menopausal cases, the treatment had to be stopped for a dangerous "worsening syndrome". Other side effects were trivial. In 28/35 cases (80%), we have found the reappearance of a pattern of estrogenic activity in vaginal smears during treatment. Hence a "simil-estrogen", more than an "anti-estrogen" mechanism of action is postulated and a selection of patients for treatment in the "mid postmenopausal age" is recommended.

Cisplatin plus vindesine versus cisplatin plus VP16 versus doxorubicin plus cytoxan in non-small-cell carcinoma of the lung. A randomized study.

From March 1981 to January 1984, 116 patients with advanced non-small-cell carcinoma of the lung (NSCCL) were randomly assigned to 3 combinations as follows: CDDP + DVA, CDDP + VP16 and DXR + CTX. 94 patients were evaluable for response, 106 for toxicity and survival. Of 31 patients, 15 (48%; 3 CRs and 12 PRs) responded to CDDP + DVA; of 33 patients, 12 (36%, 2 CRs and 10 PRs) responded to CDDP + VP16; of 30 patients, 3 (10%) obtained a PR with DXR + CTX (CDDP + DVA vs DXR + CTX, P less than 0.005; CDDP + VP16 vs DXR + CTX, P less than 0.05; CDDP + DVA vs CDDP + VP16, P = NS). The median duration of response was 22 weeks in the CDDP-DVA group, 17 weeks in the CDDP-VP16 group, and 16 weeks in the DXR + CTX group. No significant difference in survival was observed among the 3 groups (median: 43, 47, 41 weeks, respectively). Hematologic and neurologic toxicities were significantly higher in the DVA-containing regimen. Despite the lack of improvement of overall survival with the CDDP-containing combinations over the DXR + CTX control group, the good response rate makes them suitable to be used in combined therapeutic strategies.

A planned prospective study of combined treatment in stage III epithelial ovarian cancer.

In a planned prospective study 39 consecutive patients with stage III ovarian cancer have been admitted in two years. All patients have received initial extensive surgery followed on as out patients basis by 5 courses of A-Cy chemotherapy and by a second operation and further non cross resistant chemotherapy with Platinum, Hexamethyl-Melamine, Polymelphalan; 24 have been found pathologically free of disease at second surgery, and 34/39 are clinically free of disease while reporting. These data, exactly collected and evaluated are consistent with our (previously reported) empyrical observation that adjuvant surgery interspersed with courses of aggressive chemotherapy may render free of disease the majority of patients, prolong survival, and possibly cure a portion of this population.

LH-RH analogue Zoladex in the treatment of pre- and perimenopausal women with metastatic breast cancer (results of the Italian Cooperative Study).

From May 1987 to May 1989 sixty one pre- and perimenopausal women with advanced or recurrent breast cancer entered in an open non comparative study. They were treated, as a first-line therapy, with goserelin (Zoladex ICI-118630) a long acting gonadotropin-releasing hormone (LH-RH)-analogue in a depot formulation. Fifty three patients were evaluable for response; median age at entry was 41 years (range 28-56). Serum concentrations of 17 beta estradiol, LH and FSH were significantly suppressed within the first four weeks of therapy and remained suppressed for the whole duration of treatment. Subjective responses were observed, such as pain reduction and/or performance status improvement in 58% of patients. Overall objective response (CR + PR) occurred in 16 (30.2%) patients in all major sites of disease with a median time to response of 12 weeks (range 8 to 48 weeks) and a lifetable median duration of response of 36 weeks (range 16 to 76 weeks). The lifetable median time to progression was 17 weeks (range 5 to 76 weeks). Goserelin depot was well tolerated with no withdrawal due to possible adverse reactions. The observed subjective and objective response rates are comparable to those induced by surgical oophorectomy. Goserelin provides a well tolerated medical alternative to ovarian ablation, without the morbidity associated to surgery. In conclusion the present paper suggests that this innovative chemical estrogen deprivation, in premenopausal breast cancer patients, might be favorably investigated as an adjuvant therapy in future clinical trials.

Temporary occlusion of the hepatic artery plus infusion and systemic chemotherapy for inoperable cancer of the liver.

Fourteen patients with diffuse tumors of the liver were treated with temporary occlusion of the hepatic artery (HA) by an external tourniquet followed by infusion and systemic chemotherapy. Three patients had primary neoplasms (one hepatocarcinoma and two cholangiocarcinomas) and eleven had metastatic disease (nine from carcinoma of the colon and rectum, one from retroperitoneal liposarcoma, and one from pulmonary small cell cancer). Infusion chemotherapy in all patients was based on 5-FU, Mitomycin and Vincristine. Systemic chemotherapy was FIVB in metastatic carcinoma and Adriamycin in primary liver tumors. All patients showed improvement of the performance status according to the Karnofsky Index. Objective response (OR) was present in 54% of cases. At present, median survival time in 12.5 months. Aggressive treatment combining hepatic ischemia with infusion and systemic polychemotherapy seems to provide an effective method of palliation in diffuse tumors of the liver. Delayed occlusion by an external tourniquet appears safer than intraoperative ligation of the HA.

Lennert's lymphoma (lympho-epithelioid cellular lymphoma).

The authors describe a case of Lennert's lymphoma occurring in a 64-year-old male patient. After a comprehensive examination of the world literature on the disease, clinical and pathologic problems, as well as differential diagnoses from other malignant lymphoid proliferations, are discussed. This is the first observation to be reported in the otorhinolaryngologie literature.
