Overcoming resistance to chronomodulated 5-fluorouracil and folinic acid by the addition of chronomodulated oxaliplatin in advanced colorectal cancer patients.

The addition of oxaliplatin (L-OHP) to a 5-fluorouracil (5-FU)/ leucovorin (FA) regimen was retrospectively evaluated in 35 consecutive advanced colorectal cancer patients after progression of disease. L-OHP, 25 mg/m2/day, was infused from 10.00-22.00 with a peak flow at 16.00 while 5-FU, 700 mg/m2/day and FA, 150 mg/m2/day of the I-form or 300 mg/m2/day of the racemic form, from 22.00 to 10.00 with a nocturnal peak at 4.00, for 5 days every 3 weeks in 24 patients and for 4 days every 2 weeks in the other 11. Diarrhea and sensitive neuropathy were the most relevant types of toxicity (17% of patients). An objective response was achieved in 8/35 patients (23%) [95% CL 9-37], stabilization in 15 patients (43%) which included five minor responses, and progression in 12. There was no relevant difference in quality of life assessed with the EORTC QLQ C30+3 questionnaire before and after treatment. Median duration of response and median progression-free survival were 6 months; median overall survival was 11 months. This retrospective study showed that it is possible to reverse resistance to chronomodulated 5-FU by adding chronomodulated L-OHP to the previous regimen; comparison with different schedules of this combination should be performed in order to identify the best tolerated and active regimen as second-line treatment of advanced colorectal cancer.

Letrozole for the treatment of pretreated advanced breast cancer patients: preliminary report.

Twenty patients (pts) with metastatic breast cancer with disease progression, previously treated with chemotherapy and tamoxifen, were administered oral letrozole (2.5 mg/day) therapy. Fifteen of the patients were postmenopausal and 5 were premenopausal. Ten were estrogen receptor (ER)-positive, 7 were unknown and 3 were ER-negative. All the patients were assessed after 6 months (mo) of chemotherapy. Nine pts (45%) presented a partial response (PR), five (25%) had a stable disease (SD) and six (30%) had a progressive disease (PD). In the pts with PD, six out of 15 (33%) obtained a PR while undergoing tamoxifen therapy. The treatment caused no significant toxicity.

Weekly epirubicin plus lonidamine in advanced breast carcinoma.

Lonidamine has been demonstrated to potentiate the cytotoxic activity of several antineoplastic drugs, for example anthracyclines. Moreover, epirubicin is considered one of the most active drugs in advanced breast cancer, although optimal dose and schedule remains to be defined. In the present study we have treated 51 patients with advanced breast cancer with a combination of lonidamine (450 mg/day orally from day 1 throughout treatment) and epirubicin (25 mg/m2 i.v.) administered according to a weekly schedule for 24 weeks. Objective responses were observed in 29 out of 51 patients (57%; CR 16%, PR 41%). Liver metastases responded in eight out of 12 evaluable patients (67%). Average response duration was 12.4 months and median overall survival was 23 months (range 1-90+). Toxicity was negligible. The combination of weekly epirubicin and lonidamine is feasible and active in advanced breast cancer patients.

Breast cancer and timing of surgery during menstrual cycle: a 5-year analysis of 248 premenopausal women.

In the present report, we retrospectively analyzed the impact of the timing of surgery during menstrual cycle on disease-free and overall survival of 248 premenopausal patients with stage I/II breast cancer who underwent surgery followed by anthracycline-containing adjuvant chemotherapy. With a median follow-up of 5 years, no statistically significant differences were observed in disease-free or overall survival between women operated upon during the follicular (days 0-14) and the luteal (days 15-32) phase of the menstrual cycle. The impact on disease-free and overall survival of lymph-node status, tumor size and hormone receptor expression, but not of the phase of the menstrual cycle at the time of surgery, was confirmed by univariate and multivariate analysis. However, when combined with hormone receptor status, the phase of the menstrual cycle at the time of surgery proved useful to better define the prognosis of primary breast cancer patients, with significantly longer disease-free and overall survival for patients operated upon during the follicular phase and with positive hormone receptors.

Phase II study of epirubicin and vinorelbine with granulocyte colony-stimulating factor: a high-activity, dose-dense weekly regimen for advanced breast cancer.

BACKGROUND: This study was designed to explore the effectiveness and tolerability of a weekly regimen of epirubicin and vinorelbine plus granulocyte colony-stimulating factor (G-CSF). PATIENTS AND METHODS: Fifty-two patients with previously untreated advanced breast cancer were treated with epirubicin (25 mg/m2/week) and vinorelbine (25 mg/m2/week) with G-CSF support, for 24 consecutive weeks. RESULTS: The median number of courses per patient was 22 (range 10-24). The administered dose intensity was 23 mg/m2 for both epirubicin and vinorelbine. Ten complete responses (19%) and 30 partial responses (58%) were obtained, for an overall response rate of 77%. None of the patients progressed during treatment. The median response duration and time to progression were both 10 months. A total of 1065 courses were assessed for toxicity. Grade 3 neutropenia was the most common toxic manifestation, (39% of patients), without febrile neutropenia or neutropenic sepsis. Two patients had grade 3 cardiac toxicity, which regressed without sequelae. Median survival was 31 months, with a median follow-up of 24 months (range 9-40). CONCLUSIONS: Owing to its effectiveness and tolerability, the weekly regimen of epirubicin and vinorelbine plus G-CSF may represent an acceptable alternative for patients with untreated metastatic breast cancer. It could be tested in the adjuvant and neoadjuvant setting.

Recombinant human granulocyte-macrophage colony-stimulating factor plus erythropoietin for the treatment of cytopenias in patients with myelodysplastic syndromes.

In vitro studies have indicated that granulocyte-macrophage colony-stimulating factor (GM-CSF) synergizes with erythropoietin (EPO) for the production of erythroid precursors in patients with myelodysplastic syndrome (MDS). We performed a clinical trial to evaluate whether the combination of these growth factors was effective in relieving the cytopenias associated with MDS. 31 anaemic patients with low and intermediate-risk primary MDS were enrolled in a 12-week study. Therapy was initiated with GM-CSF at 1 microgram/kg/d.s.c., and then adjusted to either normalize or double the absolute neutrophil count. EPO was given subcutaneously on alternate days starting from day 2. The EPO dose was initiated at 150 U/kg and increased to 300 U/kg if after 6 weeks there was no or suboptimal erythroid response. 26 patients completed the study treatment. All evaluable cases had a neutrophil response. Clinically significant erythroid responses with increases of haemoglobin levels of at least 1 g/dl and/or reduction of transfusion needs were seen in 9/26 (34.6%), five patients improving their response after dose escalation of EPO. Treatment had no apparent effect on mean platelet counts, a single case displaying a trilineage response. An elevated bone marrow erythroid infiltration and low concentrations of circulating tumour necrosis factor-alpha were the only predictors of haemoglobin response both in univariate and in multivariate analysis. We conclude that the combination GM-CSF + EPO can abrogate neutropenia and substantially relieve transfusion requirements in a large proportion of patients with low and intermediate risk MDS. However, in vivo synergy between these growth factors for the production of erythroid precursors is not supported by our data.

The prognostic value of soluble interleukin-6 receptor in patients with multiple myeloma.

BACKGROUND: The effect of interleukin-6 (IL-6), the major growth factor for myeloma cells, may be enhanced by soluble IL-6 receptor (sIL-6R). Therefore, the current study investigated the clinical significance of serum sIL-6R in patients with multiple myeloma (MM). METHODS: Serum levels of sIL-6R were determined by enzyme-linked immunoassay in 55 normal controls, 81 individuals with monoclonal gammopathy of undetermined significance (MGUS), and 164 patients with MM in various phases of the disease. RESULTS: sIL-6R concentrations were higher in MM patients (162.0 +/- 134.6 ng/mL) than in individuals with MGUS (58.9 +/- 36.7 ng/mL) or in controls (45.6 +/- 22.3 ng/mL) (P = 0.0000). sIL-6R was not found to have a significant linear correlation with any other parameter, including IL-6, beta2-microglobulin (beta2-m), and neopterin, either in newly diagnosed cases or during the course of the disease. In addition, there were no statistically significant differences in sIL-6R concentrations between the clinical stages at the time of diagnosis. In univariate logistic regression analysis sIL-6R was a significant but weak prognostic indicator (P = 0.000000). Kaplan-Meier analysis showed that elevated levels of sIL-6R were associated with shorter survival (P = 0.00282). Patients also were stratified according to their serum beta2-m and sIL-6R levels. Patients with low levels of both parameters had a clear survival benefit over the other groups (P = 0.000000). CONCLUSIONS: The correlation between sIL-6R levels and survival is significant but weak, making it unlikely to be of much value in predicting the outcome of patients with MM alone. The results of the current study support the role of sIL-6R levels in improving the prognostic value of beta2-m and in discriminating patients with MM from individuals with MGUS.

A phase II study of irinotecan alternated with five days bolus of 5-fluorouracil and leucovorin in first-line chemotherapy of metastatic colorectal cancer.

PURPOSE: This multicenter phase II study was designed to assess the efficacy of the alternating schedule of irinotecan (CPT-11) with bolus 5-fluorouracil (5-FU) and leucovorin (LV) in first-line chemotherapy for metastatic colorectal cancer (CRC). PATIENTS AND METHODS: Patients with histologically proven metastatic colorectal cancer, and at least one bidimensionally measurable lesion, aged 18-70, with performance status < or = 2, normal baseline biological values and no prior chemotherapy (or only adjuvant chemotherapy completed > or = 6 months before study entry) were selected. Treatment was irinotecan 350 mg/m2, i.v., day 1, alternating with leucovorin 20 mg/m2 i.v. and 5-FU 425 mg/m2, i.v. daily for five consecutive days, day 22-26 (Mayo Clinic regimen). One alternating cycle was to be performed every six weeks. Patients were evaluated for efficacy every alternating cycle. Treatment was administered until five alternating cycles, disease progression, unacceptable toxicity or patient refusal. RESULTS: Thirty-three patients (28 chemotherapy-naïve and five with prior adjuvant treatment completed > 1 year prior to accrual) were enrolled. The objective response rate (RR) was 30% (95% CI: 16-49; 10 patients/33; nine partial response and one complete response). All responses were reviewed by an independent external review committee. An additional 49% of patients had stable disease. The median survival was 16 months, the one year survival amounted to 58% and the median progression free survival was 7.2 months. Relative dose intensity was nearly 90% for both drugs. Grade 3-4 diarrhea and neutropenia were the most frequent severe toxic events, seen in 24% and 64% of patients, respectively. CONCLUSIONS: The alternating schedule of CPT-11 350 mg/m2 with five days bolus of 5-FU and low dose LV is an active and feasible regimen as front-line therapy for metastatic CRC. It is well tolerated, without evidence of overlapping toxicity. The response rate appears promising with regard to that expected with either single agent. This regimen warrants further assessment in randomized trials.

13-cis retinoic acid and interferon alfa-2a in the treatment of metastatic renal cell carcinoma.

Eleven patients, pre-treated with chemotherapy and immunotherapy, with renal cell carcinoma were given 13-cis-retinoic acid (CRA) in association with interferon alfa-2a (IFN 2a). 13-ci retinoic acid was administered at the dose of 1 mg/Kg/die while interferon alfa-2a at the dose of 3X10 U.I./die s.c. All patients had been previously treated with chemotherapy in association with immunotherapy. Therapy was not discontinued until neoplastic progression occurred. Clinical results were as follows: partial responses (PR) were observed in two patients, disease stabilization (SD) in 5 and progression (PD), with 8-month median treatment duration, in 4. Side effects were mild.

Biological indices predictive of survival in 519 Italian terminally ill cancer patients. Italian Multicenter Study Group on Palliative Care.

The knowledge of prognostic factors capable of subdividing cancer patients into groups having homogenous survival times is useful even in very advanced stages of illness. This prospective multicenter study assessed these prognostic factors in 530 terminal patients with solid tumors who were undergoing only palliative care. Thirteen hematological and urinary parameters were assessed on admission and every 28 days thereafter. In 519 assessable patients with a median survival of 32 days, six biological parameters demonstrated a statistically significant predictive prognosis. A poor prognosis was predicted by high total white blood count (WBC) (P < 0.0001), high neutrophil percentage (P < 0.0001), low lymphocyte percentage (P < 0.0001), low serum albumin level (P = 0.0015), low pseudocholinesterase level (P < 0.0001), and high proteinuria (P = 0.0064). Multiple regression analysis showed that only WBC, lymphocyte percentage and pseudocholinesterase level were independent predictors of survival. The individualization of biological parameters having an independent prognostic capacity is a useful step in the attempt to identify subsets of patients with a homogeneous prognosis. The biological factors needed are easily detected by means of a simple blood test and do not require invasive operations on patients who are already debilitated.

A phase I trial of 5-day chronomodulated infusion of 5-fluorouracil and 1-folinic acid in patients with metastatic colorectal cancer.

The aim of this phase I study was to establish the maximum tolerated dose (MTD) of 5-fluorouracil (5-FU), administered as a 5-day chronomodulated infusion in combination with 1-folinic acid (FA) to ambulatory metastatic colorectal cancer patients. Consecutive cohorts of 6 patients were given 5-FU and FA infusions from 10.00 p.m. to 10.00 a.m. with peak delivery at 4.00 a.m. by means of a multichannel programmable pump. The FA dose was always the same (150 mg/m2/d). For the first cohort, the 5-FU dose level was 600 mg/m2/d at the first course, escalated by 100 mg/m2 for each subsequent cohort. Intrapatient dose was also escalated by 100 mg/m2 if toxicity was less than grade 2. The courses were repeated every 3 weeks. Thirty-four patients (17 previously treated) received a total of 154 courses. Dose-limiting toxicity consisted of stomatitis and diarrhoea. No significant haematological, cutaneous or cardiac toxicity was encountered. The MTD of 5-FU was reached at the fourth level (first course at 900 mg/m2/d equal to 4500 mg/m2/course) with 5-FU increased to 1100 mg/m2/d (5500 mg/m2/course) in 4 patients. The received 5-FU dose intensity (DI) over the first 3 courses at this level was 1318 mg/m2/week. Thirty-three patients were assessed for response. An objective response was achieved in 1 out of the 13 previously-treated and in 8 out of the 20 previously-untreated patients. The chronomodulated infusion of 5-FU at a dose of 900 mg/m2/d, together with FA at 150 mg/m2/d for 5 days, was safely delivered to out-patients with metastatic colorectal cancer. The low toxic profile and activity of this regimen in previously untreated patients deserves further exploration for the treatment of 5-FU-sensitive tumours.

Response to recombinant human erythropoietin in patients with myelodysplastic syndromes.

Recombinant human erythropoietin (rhEPO) at pharmacological doses was used to improve anemia and reduce the transfusional requirements of 43 patients with myelodysplastic syndrome (MDS). rhEPO was given by s.c. injection three times per week for 12 weeks. The EPO dose was started at 150 IU/kg and was increased to 300 IU/kg if after 6 weeks there was no or suboptimal erythroid response. Responses were defined as being a complete response (CR), partial response (PR), or no response (NR). A CR was considered a rise in untransfused hemoglobin concentrations of at least 2 g/dl or a 100% decrease in RBC transfusion requirements over the treatment period. A PR was defined as an increase in untransfused hemoglobin values of 1-2 g/dl or a decrease in RBC transfusion requirements equal to or greater than 50%. NR was defined as responses less than a PR. Patients who responded to therapy were continued on rhEPO at the same dose for 6 additional months. An objective response (CR and PR) was observed in 7 of 42 (16.7%) assessable cases after 6 weeks of treatment at the dose of 150 IU/kg. Dose escalation (300 IU/kg) in nonresponders resulted in another six patients attaining a rise in hemoglobin concentrations. The final response rate was 13 of 41 (31.7%); 4 patients became transfusion independent. Therapy was tolerated well, with no relevant side effects. MDS progression was seen in one case. An elevated bone marrow erythroid infiltration (erythroid index) and detectable pretreatment circulating erythroid progenitors (burst-forming units-erythroid) were the best predictors of hemoglobin response when we controlled for other variables. These data suggest that rhEPO has a role in the treatment of certain patients with MDS, particularly in those with a high erythroid index and detectable circulating erythroid burst-forming units.

Vinorelbine neurotoxicity: clinical and neurophysiological findings in 23 patients.

Vinorelbine (5'-noranhydrovinblastine) is a new semisynthetic antineoplastic vinca alkaloid which interfers with axonal transport, inducing spiralisation of axonal microtubules and resulting in peripheral neurotoxicity. A prospective detailed neurological and electrophysiological evaluation was performed in 23 patients treated with 25 mg vinorelbine a week. All patients developed a sensory-motor distal symmetric axonal neuropathy. The neurotoxicity increased with cumulative vinorelbine doses and peripheral neuropathy was mild or moderate in most patients. After discontinuation of vinorelbine treatment, neuropathic signs and symptoms were partially reversible.

Chronomodulated 5-day infusion of floxuridine and L-folinic acid in patients with advanced malignancies: a feasibility and tolerability study.

The best schedule for administering floxuridine (FUDR) has not yet been established. Duration of infusion, need (and dosage) of leucovorin (folinic acid, FA), and circadian timing need to be further specified. Nevertheless, FUDR delivery according to circadian rhythms has allowed increase of dose intensity without enhancing the side effects. A 5-day infusional schedule combining FUDR and L-FA was devised as an attempt to increase dose intensity and to provide therapy every 3 weeks to patients with advanced cancer. An ambulatory programmable-in-time pump was used for this purpose. Fourteen patients entered this trial. Two dose levels (mg/kg x 5 days) were evaluated: 0.5 mg/kg/day in six patients and 0.525 mg/kg/day in eight patients. Both patient groups received a concurrent infusion of L-FA 10 mg/m2/day i.v. The delivery patterns of both FUDR and L-FA varied sinusoidally during the 24 hours with a maximum at 18.00 hours. Courses were repeated every 3 weeks. Of 35 courses, treatment produced mucosites greater than grade 2 in only two of them. No severe diarrhea, the dose-limiting toxicity of FUDR when infused over 14 days, was encountered at the dose levels tested. This 5-day chronotherapy schedule allowed delivery of a larger amount of FUDR than the flat delivery described in a previous report. A daily dose of 0.525 mg/kg FUDR, combined with 10 mg/mg2 L-FA, with intraindividual dose escalation according to tolerance, is recommended for future investigations of the activity of this chronotherapy schedule.

Personality, inner experience and compliance in advanced cancer patients treated with external pumps.

The presence of portable pumps for protracted infusional chemotherapy in metastatic solid tumors at an advanced stage determines the need to evaluate psychologically the inner experience of the patients in relation to this therapeutic modality. The objective of the study were to analyze personality variables (coping and awareness), inner experience variables (acceptance and expectations) and the compliance of the patients during repeated courses of therapy. In addition we evaluated the influence of sex, age, level of education and response to treatment in relation to these variables. From February 1992 to March 1994 we evaluated 50 metastatic patients with a psycho-dynamic interview at the 1st, 3rd, 6th and the 9th course of therapy. The data obtained showed a positive trend for all the variables examined and in all the subgroups (age, sex, level of education, response) up to the 6th course. After the 6th course, personality variables remained stable, yet a drop in variables related to inner experience and compliance was observed in the whole group. While the personality variables remain constant in all patients, a decrease of acceptance and expectation was observed in patients non responding to therapy for their tumor, a trend which becomes significative at the 9th course regards expectation. The use of a psycho-dynamic interview allowed us to evaluate the effect of treatment on psychological variables and compliance to therapy. The length of treatment and the response to treatment seem to influence the more profound inner experiences of the patients.

Medical oncology and home care in Italy.

AIMS AND BACKGROUND: Home care programs are designed to provide care for cancer patients in their homes. Aim of the study is to describe the activities of home care program, to examine the organization and efficiency of this type of care in Italy. METHODS: A questionnaire was sent to the regional representatives of the National Society of Medical Oncology and to the regional health departments. RESULTS: a) the home care program is uniformly distributed throughout the country; b) the number of personnel in the different centers varies greatly from one area to another; c) approximately 50% of the centers do not cover emergency situations (at night or on holidays); and d) there is little involvement of the public sector. CONCLUSIONS: In spite of these problems, the home care system is taking on a fundamental role, especially for advanced cancer patients.

Effective control of CMF-related emesis with high-dose dexamethasone: results of a double-blind crossover trial with metoclopramide and placebo.

To establish the antiemetic activity of both dexamethasone (DXM) and metoclopramide (MCP) in patients receiving i.v. cyclophosphamide, methotrexate, and 5-fluorouracil (CMF), 25 women with stage II breast cancer were entered into this study. A randomized, double-blind, crossover design was employed to evaluate DXM (24 mg in 5 doses) versus MCP (1 mg/kg as a single dose) versus a combination of both drugs (as above) or placebo (PLC). The patients were requested to complete a questionnaire evaluating the antiemetic effect. All but one patient completed the planned antiemetic program during the first four CMF courses. As compared to PLC, both the DXM-MCP combination and DXM alone provided a higher complete antiemetic protection rate (p = 0.01 and p = 0.006, respectively). The DXM regimens were more effective than both PLC (p = 0.004 and p = 0.01) and MCP (p = 0.002 and p = 0.006) in reducing the prevalence of severe vomiting. As compared to MCP, the DXM regimens provided a better control of the nausea (p less than 0.04 and p less than 0.01) and reduced both the episodes and the duration of vomiting (p less than 0.02 and p less than 0.05). The DXM regimens were also associated with a better patient opinion than the PLC (p less than 0.002 and p less than 0.0002). No significant differences were found between MCP and PLC, nor between the DXM regimens. Except for two dystonic reactions, MCP-related toxicity was mild, whereas that induced by DXM was negligible in patients with no contraindications to corticosteroids. As employed in this study, DXM provided safe and effective antiemetic protection for patients receiving adjuvant i.v. CMF. Data available do not support the use of a short-course MCP, either alone or in combination with DXM. The search for better antiemetic treatments is mandatory, especially for patients receiving adjuvant chemotherapy. To date, we recommend the use of DXM as a standard regimen and as a control for further studies.
