High-dose thiotepa and melphalan with hemopoietic progenitor support following induction therapy with epirubicin-paclitaxel-containing regimens in metastatic breast cancer (MBC).

BACKGROUND: Preliminary data from phase III randomized studies have failed to show benefit of HDC given as consolidation after anthracycline and alkylating-based chemotherapy in metastatic breast cancer (MBC). Moderate activity of induction regimens and selection of chemoresistant clones are among the possible reasons for these disappointing results. We therefore have designed a phase II study where high-dose alkylating agents are given as consolidation after an induction treatment including the most active agents (epirubicin and paclitaxel) without alkylating agents. PATIENTS AND METHODS: Patients with MBC not previously treated with chemotherapy for metastatic disease were eligible. After six courses of epirubicin-paclitaxel +/- gemcitabine patients received a course of thiotepa 600 mg/m2 + melphalan 160 mg/m2 with hemopoietic support. Pharmacokinetic parameters of thiotepa and melphalan were measured and related to treatment outcomes. The L-VEF of the patients was monitored before and after treatment. RESULTS: Forty-eight patients have been treated. Before HDC 14 patients were in CR, and 34 in PR. A median of 6.92 x 10(6) (range 1.53-16.6) CD34+ cells/kg were reinfused after HDC. Median days (range) to neutrophils > 0.5 x 10(9)/l and platelets > 20,000 x 10(9)/l were 9.5 (9-33) and 10 days (9-32), respectively. Symptomatic CHF was observed in two patients (4.1%). Cmax and AUC of thiotepa showed a linear relationship with time to progression (TTP) and overall survival (OS): r2 = 0.6. After HDC the conversion rate from PR to CR was 44.1%. At five years progression-free and overall survival rates are 37.5% and 65%, respectively. A treatment-related death was observed. CONCLUSIONS: High-dose thiotepa and melphalan after an epirubicin-paclitaxel-containing treatment is feasible, devoid of significant cardiotoxicity and very active. Pharmacokinetic parameters of high-dose thiotepa might be linked to treatment outcome.

Epirubicin/taxane combinations in breast cancer: experience from several Italian trials.

Doxorubicin/paclitaxel (Taxol) combinations are very active in advanced breast cancer, with objective response rates up to 90%, but have shown a high incidence of cardiotoxicity. A phase I/II trial replacing doxorubicin with epirubicin (Ellence), a less cardiotoxic analog, produced an objective response rate of 84%, but with a low rate of cardiotoxicity. A careful cardiac monitoring in more than 100 patients treated with this combination has demonstrated that the risk of congestive heart failure is below 10% up to a cumulative epirubicin dose of 990 mg/m2. To examine the possibility that the pharmacokinetic and pharmacodynamic interactions that occur when anthracycline and paclitaxel are administered together might result in subadditive antitumor activity, a phase III study is comparing concomitant vs sequential administration of epirubicin and paclitaxel in patients with advanced breast cancer. A phase I/II study of epirubicin plus docetaxel as first-line chemotherapy for advanced breast cancer patients evaluated the maximum tolerated doses and for subsequent studies recommended epirubicin at 75 mg/m2 plus docetaxel at 80 mg/m2. In the adjuvant setting, an ongoing phase III trial is comparing epirubicin plus paclitaxel vs FEC (fluorouracil, epirubicin, and cyclophosphamide [Cytoxan, Neosar]) in node-positive patients. Preliminary data confirm the cardiac safety of these treatments.

New combinations with epirubicin in advanced breast cancer.

Several trials have shown that anthracyclines and taxanes can be combined to achieve response rates ranging from 70% to 90%, with complete responses ranging from 19% to 41%. In an attempt to increase the activity while maintaining tolerability, gemcitabine (Gemzar) was added to the epirubicin (Ellence)/paclitaxel (Taxol) regimen. Among 36 metastatic breast cancer patients treated with this new combination, the overall response rate was 92%, including 31% with a complete response. Another attempt to improve the outcome of metastatic breast cancer patients involves a phase III multicentric randomized trial (MANTA-1) to evaluate if paclitaxel maintenance therapy after anthracycline/taxane combination therapy can improve time to progression and overall survival. Although anthracyclines are more frequently used in the adjuvant setting, it is important for the clinicians to know whether this class of drugs can be used again for those patients who develop metastatic disease. An analysis of 312 patients treated with epirubicin containing regimens as first-line treatment for metastatic disease shows that epirubicin-based regimens are active in patients already exposed to anthracyclines in the adjuvant setting, and that the risk of cardiac toxicity is low up to a cumulative epirubicin dose of 990 mg/m2.

A randomized study comparing two different schedules of administration of cisplatin in combination with gemcitabine in advanced nonsmall cell lung carcinoma.

BACKGROUND: This randomized trial was designed to investigate the feasibility, toxicity, and activity of two different schedules of gemcitabine plus cisplatin in previously untreated patients with advanced (International Union Against Cancer (UICC) Stage IIIB-IV) nonsmall cell lung carcinoma (NSCLC). METHODS: From February 1997 to September 1998, 82 patients with advanced NSCLC were entered onto the study and were randomized to gemcitabine 1000 mg/m(2) on Days 1, 8, and 15 plus cisplatin 80 mg/m(2) on Day 2 (arm A) or Day 15 (arm B) every 28 days. RESULTS: All the patients were assessable for toxicity (arm A/arm B: 151/177 cycles; median, 4 of 5 cycles per patient), and the following Grade 3-4 toxicities were reported (percentage of cycles in arm A vs. arm B): anemia, 7.9% and 2.3% (P < 0.05); leukopenia, 6.0% and 6.7%; thrombocytopenia, 15.0% and 1.6% (P < 0.01); no World Health Organization (WHO) Grade 3-4 nonhematologic toxicities were observed. These side effects led to gemcitabine dose reductions in 35.1% of courses in arm A and 22.0% of courses in arm B (P < 0.05) and to gemcitabine omissions in 28.5% of courses in arm A versus 7.3% of courses in arm B (P < 0.01). Dose intensities (DIs) of gemcitabine were 607.5 mg/m(2)/week in arm A and 711.6 mg/m(2)/week in arm B (P < 0.01); DIs of cisplatin were 18. 1 mg/m(2)/week in arm A and 18.8 mg/m(2)/week in arm B. The total delivered doses of gemcitabine were 9315.5 mg/m(2) in arm A and 12, 631.0 mg/m(2) in arm B (P < 0.01); the total delivered doses of cisplatin were 277.1 mg/m(2) in arm A and 333.0 mg/m(2) in arm B (P < 0.01). Response rates according to intention to treat were 40.4% (95% confidence interval [CI], 25.5-55.3) in arm A and 45% (95% CI, 29.5-60.5) in arm B. The overall median duration of response was 7.4 months; the median time to disease progression was 6 months (95% CI, 3-9) in arm A and 9 months (95% CI, 4-14) in arm B (P < 0.02); the median overall survival was 10 months (95% CI, 7.0-12.5) in arm A and 17 months (95% CI, 13.0-21.6) in arm B (P < 0.01); the 1-year survival rates were 34% and 63%, respectively. CONCLUSIONS: Our data show that arm B (cisplatin on Day 15) is less toxic than arm A (cisplatin on Day 2) and allows the administration of significantly higher total doses and dose intensities of chemotherapy. No significant differences in response rates were observed between the two schedules; patients on arm B experienced a significantly more prolonged progression free and overall survival; however, the study was not powered to detect differences in these outcomes.

Gemcitabine monotherapy in elderly patients with advanced non-small cell lung cancer: a multicenter phase II study.

BACKGROUND: This trial investigated the activity and toxicity of gemcitabine in previously untreated elderly (> 70 years) patients with advanced (stage IIIB-IV) non-small cell lung cancer (NSCLC). PATIENTS AND METHODS: From January 1997 to July 1998, 46 patients with advanced NSCLC aged over 70 years with a performance status of 0-2 were entered into the study. Gemcitabine 1000 mg/m2 was administered as a 30-min infusion once a week for 3 weeks followed by a week of rest; cycles were repeated every 4 weeks. RESULTS: Forty-four patients were evaluable for response. One complete response and nine partial responses were observed, for an overall response rate of 22.2% (95% C.I.: 11.3-37.5). The median time to disease progression was 5.1 months (95% C.I.: 3.5-6.7), the median duration of response was 6.3 months, and the median overall survival time 6.75 months (95% C.I.: 5.3-8.2). All patients were evaluable for toxicity (184 cycles, median = 3 cycles/patient) and no grade 4 hematologic toxicities were reported. WHO grade 3 leukopenia, neutropenia and anemia occurred in 3.3, 0.5 and 1.1% of cycles, respectively. Grade 3 skin rash occurred in 4.3% of patients. These side effects led to treatment discontinuation in two patients. CONCLUSION: Our data show that gemcitabine is active and well tolerated in patients aged over 70 years with advanced NSCLC.

Octreotide acetate long-acting release in patients with metastatic neuroendocrine tumors pretreated with lanreotide.

BACKGROUND: In the present study we investigated the efficacy and tolerability of i.m. octreotide acetate (octreotide LAR) in patients with metastatic neuroendocrine tumors (NETs) previously treated and failed on i.m. lanreotide. PATIENTS AND METHODS: Fifteen patients (8 females, 7 males, median age 67 years, range 28-81 years) with metastatic NETs (8 endocrine pancreatic tumors, 7 midgut carcinoids) were enrolled in the study. All patients were in progressive disease (objective: 11 patients, symptomatic: 10 patients, biochemical: 11 patients) after treatment with slow release lanreotide, 30 mg every 14 days for a median time of 8 months (range 3-19 months). All patients had measurable disease; 12 patients had elevated serum and/or urine markers and 11 were symptomatic. Octreotide scintigraphy was positive in 13 of 15 patients. Octreotide LAR was administered as i.m. injection at the dose of 20 mg every four weeks until disease progression. RESULTS: An objective partial response (PR) was documented in one patient (7%), no change (NC) in six (40%), and progressive disease (PD) in eight patients (53%). The PR was observed in one patient with non-functioning endocrine pancreatic tumor with progressive liver and lymph node metastases after 16 months of i.m. lanreotide therapy. The median duration of disease stabilization was 7.5 months (range 6-12+ months). The overall biochemical response rate was 41%, including CRs (33%) and PRs (8%); biochemical responses were observed in carcinoids as well as in endocrine pancreatic tumors; the median duration of response was 5 months for CRs and 7.5 months for PRs. The overall symptomatic response rate was 82%. The median duration of response for diarrhoea, abdominal pain, or both was 6.5 months (range 3-12+ months). Improvement in performance status (PS) was obtained in 5 of 11 patients with PS of 1 at study entry. Median duration of octreotide LAR treatment was seven months (range 3-12+ months). No serious adverse events were reported; mild side effects were reported in 26% of patients. CONCLUSIONS: Octreotide LAR 20 mg shows significant efficacy in terms of objective response rate (PR + SD), biochemical and symptomatic control in patients with metastatic NETs of the GEP system pretreated and progressing on slow release lanreotide.

Geographical variations of place of death among Italian communities suggest an inappropriate hospital use in the terminal phase of cancer disease.

This study aimed to assess geographic variations of place of death among Italian communities, to investigate the determinants of home death, and to examine trends in the proportion of home deaths over a period of 8 y. A cross-sectional analysis was performed on 13 provinces from two Italian regions (Liguria and Toscana), and the geographic variations and determinants of home death were studied for the 17,597 residents, who died of cancer in 1991. Trends for both the regions of the proportion of home deaths were examined for the period 1987 and 1995. A remarkable heterogeneity in the observed proportion of home deaths among the 13 provinces was observed, ranging between 31.4 and 40.4% in Liguria and between 37.7 and 73.3% in Toscana. The estimated proportion of home deaths after adjustment for age, gender, marital status, education, place of birth, characteristics of the living area, and cancer site remained substantially the same. The proportion of home deaths significantly increased with increasing age, and years of education. It was higher among females, married and widowed patients, native patients, and for residents in a semi-urban or rural areas. A significant decrease in the percentage of patients who died at home between 1987 and 1995 in both regions was observed. The wide geographical and social differences observed between and within the communities for the frequency of home deaths are not explained by the distribution of known determinants, and possibly suggest patterns of inappropriate hospital admissions in the terminal phase of disease.

Long-acting depot lanreotide in the treatment of patients with advanced neuroendocrine tumors.

Long-acting depot forms of somatostatin analogs administered by intramuscular injections are now available for the treatment of neuroendocrine tumors (NETs). In the present study, we investigated the efficacy and tolerability of a slow-release form of lanreotide in patients with advanced NETs. From July 1996 to January 1999, 25 patients with advanced NETs (12 carcinoids, 13 endocrine pancreatic tumors) were enrolled in the study. Thirteen patients were pretreated with subcutaneous octreotide, chemotherapy, or hepatic metastasis alcoholization. All the patients had measurable disease. Seventeen patients were symptomatic and 20 patients had elevated serum and/or urine markers. Octreotide scintigraphy was positive in 23 of 25 patients. Lanreotide was administered as intramuscular injections at the dose of 30 mg every 2 weeks until there was objective, biochemical, or symptomatic tumor progression. Objective partial responses (PRs) were documented in 2 patients (8%), whereas 10 patients (40%) had tumor stabilization. The PRs were observed in patients with midgut carcinoids, of whom one was pretreated with subcutaneous octreotide. The response duration was 21+ and 24+ months in responding patients; the median duration of disease stabilization was 8.5 months (range, 4-21+). The overall biochemical response rate was 42%, including 2 complete responses (CRs) (10.5%) and 6 PRs (31.5%); all biochemical responses were observed mostly in patients with carcinoid tumors; the duration of response was 18+ and 30+ months for CRs; the median duration of biochemical response was 7 months (range, 4-18+) for PRs. The overall symptomatic response rate was 70% with a median duration of 7.5, 18, and 18+ months for diarrhea, abdominal pain, and flushing, respectively. Median duration of lanreotide treatment was 10 months (range, 2-30+). No significant side effects were reported. Depot lanreotide 30 mg shows significant efficacy in terms of objective response rate and in biochemical and symptomatic control, in pretreated patients as well as nonpretreated patients with advanced NETs. Tolerability is good, with good patient compliance.

Oral doxifluridine in advanced hepatocellular carcinoma: A phase II study.

Hepatocellular carcinoma (HCC) remains one of the most common neoplasms in the world. Doxifluridine is an oral fluoropyrimidine derivative activated to 5-fluorouracil by uridine phosphorylase which is more expressed in malignant cells. Therefore, we conducted a phase II study to evaluate the activity of oral doxifluridine in patients with advanced hepatocellular carcinoma. Twenty-five advanced hepatocellular carcinoma patients entered the study; doxifluridine was given orally at the initial daily total dose of 2,250 mg for 4 consecutive days every week. All patients are evaluable for toxicity: these included mainly grade 1-2 (WHO) diarrhea, stomatitis, nausea and vomiting; 4 patients (16%) experienced grade 3-4 diarrhea. Twenty-four patients are evaluable for response and 1 complete and 3 partial responses have been observed (response rat 17%, 95% confidence interval: 5-37). Oral doxifluridine at the dose and schedule we used, although having only modest activity in advanced HCC, may represent an alternative to other frequently used chemotherapeutic agents, because of its favorable toxicity profile and its simple route of administration.

The gemcitabine/epirubicin/paclitaxel combination in advanced breast cancer.

The purpose of this study was to determine the response rate of the gemcitabine/epirubicin/paclitaxel combination (GET) and its feasibility as induction chemotherapy before high-dose consolidation treatment in patients with metastatic breast cancer. Patients received gemcitabine 1,000 mg/m2 on days I and 4, epirubicin 90 mg/m2 on day 1, and paclitaxel 175 mg/m2 on day I every 3 weeks for up to eight courses. After six courses of GET, responding patients or those with stable disease entered a high-dose chemotherapy program. All 36 enrolled patients were evaluated for toxicity and response. The GET combination was well tolerated, with myelosuppression the being most common toxicity; grade 4 neutropenia was reported in 56% of patients. The overall response rate was 89% (95% confidence interval, 73.4% to 96.9%), with a 28% complete response rate. The high-dose chemotherapy program resulted in a response rate of 92% and a complete response rate of 44%. As a result of the promising activity demonstrated in this phase II study with GET and following high-dose chemotherapy, three related studies are planned: an in vitro study evaluating the possible synergism of paclitaxel and gemcitabine, a phase III study comparing GET with epirubicin/paclitaxel in metastatic breast cancer, and a phase II trial evaluating GET in patients with operable breast cancer.

Total and functional hepatic blood flow decrease in parallel with ageing.

OBJECTIVES: To study changes in hepatic blood flow with age. DESIGN: Functional hepatic flow (FHF) and total hepatic flow (THF) were determined by non-invasive methods in 40 normal subjects in four age groups (<45, 45-60, 61-75 and >75 years). All subjects had normal routine liver function tests and no history of liver disease. RESULTS: THF was measured by pulsed echo-Doppler, as the sum of portal and hepatic artery blood flow; FHF was measured by the hepatic clearance of D-sorbitol. THF significantly decreased with age, particularly in subjects over 75 (from 1445+/-220 ml/min to 1020+/-148; P<0.001), and a similar reduction was observed in FHF (from 1514+/-250 ml/min to 1015+/-163; P<0.001). THF and FHF were strictly correlated in the whole population (r = 0.871; P<0.001) and both correlated with age (r = -0.510 and r = -0.596; P<0.005). CONCLUSION: With ageing there is a reduction of hepatic blood flow without any additional intrahepatic shunting.

Cardiotoxicity of epirubicin/paclitaxel-containing regimens: role of cardiac risk factors.

PURPOSE: To evaluate the incidence of clinically relevant cardiac toxicity after treatment with epirubicin/paclitaxel-containing regimens in patients with metastatic breast cancer and to identify high-risk patients in whom the benefit of chemotherapy may be negated by the occurrence of congestive heart failure (CHF). PATIENTS AND METHODS: A total of 105 patients who were referred for epirubicin/paclitaxel treatment were included in this study. Treatment regimens were as follows: (1) epirubicin 90 mg/m(2) plus paclitaxel 135 to 225 mg/m(2) over 3 hours (n = 76); and (2) gemcitabine 1,000 mg/m(2) on days 1 and 4 plus epirubicin/paclitaxel (n = 29). The occurrence of CHF was detected by physical examination, and left ventricular function was evaluated by bidimensional echocardiography to support the diagnosis. Cardiac risk factors examined in this study included age, prior radiotherapy to the chest, hypertension, and diabetes. RESULTS: No patient experienced CHF while on treatment. Nine patients (9%) developed CHF after cumulative epirubicin doses of 1,080 mg/m(2) (n = 4), 720 mg/m(2) (n = 2), 630 mg/m(2) (n = 1), and 540 mg/m(2) (n = 2). One of the two patients who developed CHF after a cumulative epirubicin dose of 540 mg/m(2) had received consolidation with high-dose chemotherapy. Median time to appearance of cardiologic symptoms was 3 months after the end of treatment (range, 3 to 6 months). Overall, the incidence of CHF was 13% and 4% in patients with or without cardiac risk factors, respectively. The cumulative risk of developing CHF was estimated as 7.7% at a cumulative doses of 720 mg/m(2) and 48.7% at a cumulative dose of 1,080 mg/m(2). CONCLUSION: This study shows that the incidence of CHF after an epirubicin/paclitaxel regimen is low up to cumulative epirubicin doses of 990 mg/m(2), thus allowing the safe administration of this regimen even in patients who received epirubicin in the adjuvant setting. However, the risk of developing CHF increases when a cumulative dose exceeding 990 mg/m(2) is reached, concomitantly with the presence of an additional cardiac risk factor.

AIDS related neoplasms in Genoa, Italy.

The study defines the epidemiological characteristics of HIV-infection in the population of Genoa and estimates the entity of AIDS-cancer association. The cohort includes 317 subjects resident in the Municipality of Genoa, aged above 14 years and notified prior to 31 December 1991 and/or dead from AIDS in the period 1988-1991. From 1984 to 1991, 44 cases of tumour were recorded. The comparison between the rate ratios found in the AIDS patients' cohort and in the general population of Genoa strengthen the significant association highlighted in literature regarding overall cancer, 26.7 (p < 0.05), and in particular, Kaposi's sarcoma, 3239.4 (p < 0.05); non-Hodgkin's lymphomas, 84.8 (p < 0.05); Hodgkin's lymphomas, 20.6 (p < 0.05). Moreover, a significant increase in the risk of testicular seminoma, 61.5 (p < 0.05) and lung cancer, 18.0 (p < 0.05) is confirmed.

Functional hepatic flow and Doppler-assessed total hepatic flow in control subjects and in patients with cirrhosis.

Functional hepatic flow and total hepatic flow were determined by non-invasive techniques in 32 patients with cirrhosis and in 32 paired control subjects. Functional hepatic flow was measured by the hepatic clearance of D-sorbitol, while total hepatic flow was determined by pulsed echo-Doppler, as the sum of portal and hepatic arterial blood flow. Functional hepatic flow was significantly reduced in patients with cirrhosis (927 +/- 314 vs. 1287 +/- 315; p < 0.0001), while total hepatic flow was slightly increased (1511 +/- 540 vs. 1261 +/- 321 in controls; p = 0.028). In control subjects functional hepatic flow significantly correlated with total hepatic flow (r = 0.823; p < 0.001), while no correlation was observed in cirrhosis. Functional hepatic flow and the difference between total hepatic flow and functional hepatic flow significantly correlated with the Child-Pugh score in patients with cirrhosis. The data obtained in control subjects support the measurement of functional hepatic flow and total hepatic flow by non-invasive techniques. The finding that in cirrhosis functional hepatic flow is significantly decreased, while Doppler-assessed total hepatic flow is preserved or even increased, confirms that a relevant part of blood flowing through the liver is diverted by intrahepatic shunts. The simultaneous assessment of these two parameters by non-invasive techniques may be proposed as a reliable tool for the study of functional shunting of cirrhosis.

[Experimentation with Di Bella polychemotherapy in Tuscany].

The study reports the experience of Di Bella Treatment (an unconventional treatment for cancer) for advanced cancer patients in Tuscany. A total of (38 + 140 + 463) patients were treated (38 phase II study, 140 observational study and 463 distributional study) and all the case report forms were collected and analyzed in the Regional Coordinator Center of Pisa. No objective response was observed; as of May 31, 1999 63 patients are in stable disease (1 phase II, 3 observational and 59 distributional study). Percentage of interruptions to treatment due to death, refusal and toxicity were similar between patients O and D, while there are significant differences in terms of progressive disease (O = 52% vs D = 18%) and number of losts to follow up (40% in distributional study). The median duration of treatment was 2.31 months (range: 0-15) in the observational study and 3.2 months (range: 0-13) in the distributional study. The median overall survival time (4.5 months) and the median time to disease progression (2.7 months) were calculated by Kaplan-Meier Method and were based on all treated patients (intention to treat population). Follow-up of the study was stopped at 31.05.1999.

[Hospital admissions, diagnostic and therapeutic procedures of patients with colorectal cancer during 5 years after diagnosis: population-based study].

This research evaluated basic parameters of care, also in the terms of costs. The study examined a sample of colorectal cancer cases incident in 1987 in the population of Florence's municipality, taken from the data base of Tuscany Cancer Registry (RTT). We collected, for 71 patients, all clinical records, for the five follow-up years and evaluated the diagnostic and therapeutic procedures (blood tests, histologic examination, instrumental investigation and surgical intervention) and the duration of all hospitalisations. Besides, on the basis of the diagnostic and therapeutic procedures and of the discharge diagnosis, each hospitalisation was coded following the DRG system and the economic cost of hospital care was analysed. The average number of hospitalisations and the average length of stay for patient in five follow-up years are respectively 1.9 (SD = 1.3) and 41.3 (SD = 25.8); the length of stay resulted highly correlated with the stage of disease. The mean hospital cost per patient (about ItL 18.000.000 overall) was higher in patients with more advanced disease at diagnosis. In the period of study an average 125.9 blood tests (SD = 110.7), 1.2 histologic examinations (SD = 0.9) and 10.3 instrumental investigations (SD = 9.0) were performed for each patient; 61 subjects (86%) were submitted to surgical intervention, of which 4 had a second intervention, and 1 subject was submitted to surgical intervention for liver's metastases.
