Single-agent vinorelbine in pretreated breast cancer patients: comparison of two different schedules.
This retrospective study compared toxicity and activity of vinorelbine according to two schedules with different projected dose intensities in heavily pretreated breast cancer patients. Forty patients were assessable for toxicity and activity in each group; group A received vinorelbine 25 mg/m2 week + lenograstim (150 microg/m2 s.c. on day 3); group B received 25 mg/m2 on days 1 and 8 every 3 weeks. The projected dose intensity was 25 mg/m2/week and 16.6 mg/m2/week, and delivered dose intensity 95.2% and 94.5% in group A and B, respectively. Grade 3-4 afebrile neutropenia was recorded in 25% and 37.5% of patients in A and B, respectively. Overall response rate, 52.5% and 35%; no change, 35% and 40%; progression of disease, 12.5% and 25% in A and B, respectively. Median duration of the response was 10 months for group A and 7 months for B. Median time to progression: 9.0 months and 4.0 months for A and B, respectively. At a median follow-up of 45 months for group A and 19 months for group B, median overall survival was 19 months and 16, respectively. In conclusion the results of the study showed that dose intensity of vinorelbine could have an improvement in terms of time to progression in pretreated advanced breast cancer.

Single-agent oxaliplatin in pretreated advanced breast cancer patients: a phase II study.
PURPOSE: Oxaliplatin (L-OHP), a new platinum analogue, is an active drug in colorectal and ovarian cancer. In this phase II study we explored tolerability and activity of oxaliplatin as a single agent in metastatic breast carcinoma patients. PATIENTS AND METHODS: Fourteen anthracycline pretreated advanced breast cancer patients were enrolled. Oxaliplatin was given at 130 mg/m2 on day 1 and repeated every three weeks. Analysis of toxicity, response rate and survival was performed. RESULTS: The median number of courses per patient was four (range 2 6). The median administered dose-intensity was 43.3 mg/m2/week (range 32.5-43.3) which represents 100% of projected dose-intensity. No severe toxicity was encountered. Three patients developed acute transient laryngeal symptoms. Three patients displayed a partial response (21%), (95% confidence interval (CI): 0%-43%), two stable disease (14%) and nine progressed (64%). Response lasted five, four and five months respectively. Median survival was 12 months. CONCLUSIONS: In this limited experience, oxaliplatin appeared to be well tolerated and moderately active in advanced anthracycline-pretreated breast cancer patients. Combination chemotherapy with other active drugs such as 5-fluorouracil (5-FU), anthracyclines and taxanes should represent the next step of development of this new drug.

Role of P53 and BCL-2 in high-risk breast cancer patients treated with adjuvant anthracycline-based chemotherapy.
PURPOSE: Adjuvant therapy has become an integral component of the managment of primary high-risk breast cancer patients. However, a considerable fraction of women receive no benefit from this treatment. This study investigates whether a number of biopathological factors can influence the outcome of patients submitted to adjuvant chemotherapy involving the use of high-dose epirubicin and cyclophosphamide. METHODS: One hundred and fifty-seven primary breast cancer patients, considered at high risk according to the St. Gallen Meeting Consensus Conference, were evaluated immunohistochemically for estrogen, progesterone receptors, p53, bcl-2, HER-2/neu, and Ki-67, of which the results were correlated with patient outcome. RESULTS: Results obtained demonstrated that p53 is a significant predictor of disease-free survival (DFS P < 0.0001) and overall survival (OS P = 0.0002) both in ductal and lobular carcinomas, whereas bcl-2 expression seems to be of prognostic value only in lobular carcinomas (DFS P = 0.01; OS P = 0.02). CONCLUSIONS: This data indicates that in high-risk breast cancer patients the immunohistochemical evaluation of p53 and bcl-2 may be of clinical value in distinguishing different responses to adjuvant anthracycline-based chemotherapy.

Weekly schedule of vinorelbine in pretreated breast cancer patients.
PURPOSE: In this phase II study, we explored tolerability and activity of vinorelbine administered according to a dose-dense weekly schedule with hematopoietic growth factor support in pretreated, advanced breast cancer patients. PATIENTS AND METHODS: From January 1994 to March 1996, 40 patients with metastatic breast cancer, pretreated with at least one prior anthracycline-containing regimen, were entered into the study. PATIENT CHARACTERISTICS: median age 53 years (range 32-70); ECOG performance status 0-1: 34 patients, 2: 6 patients; dominant visceral metastatic disease: 15 patients, dominant non-visceral: 25; anthracycline-refractory/resistant: 2 patients, sensitive: 38 patients. Six patients were treated as first-line therapy for metastatic disease and 34 in second- or subsequent lines. All patients received vinorelbine at the dose of 25 mg/m2/week as a short intravenous infusion, together with routine antiemetic medication. Granulocyte-colony stimulating factor (Lenograstim) at the dose of 150 microg/m2 subcutaneously on day 3 was included in the treatment schedule. RESULTS: The median number of treatment weeks was 23 (range: 4-24), with a delivered dose-intensity (DDI) of 23.8 mg/m2/week (range: 18.7-25, 95.2% of projected dose-intensity). Toxicity was mild, with non-complicated neutropenia being the main toxicity observed (grade 3-4 in 25% of the patients but only 2% of treatment weeks). Overall response rate was 52.5%, with complete responses in 12.5% of patients. Median duration of the response and median time to progression were 10 and 9 months, respectively. Median overall survival was 19 months. CONCLUSION: Dose-dense weekly vinorelbine is safe and effective with minimal toxicity in pretreated advanced breast cancer patients.

Toxicity and activity of docetaxel in anthracycline-pretreated breast cancer patients: a phase II study.
Docetaxel has proven effective in advanced breast cancer. Myelosuppression and cumulative fluid retention syndrome are troublesome, potentially avoidable toxicities. In this consecutive cohort study, docetaxel (100 mg/m2 by 1 hour i.v. infusion, q3 weeks) activity and toxicity was explored in 56 anthracycline-pretreated patients (eligible: 55: median age: 51 years [range: 28-68 years]; median performance status: 0 [range: 0-3]) with metastatic breast cancer, using two different granulocyte colony-stimulating factor and steroid pre- and postmedication schedules. Twenty-nine patients (group A) received a 5-day oral prednisone premedication, and 26 (group B) received 4-day low-dose i.m. dexamethasone; group B patients also received prophylactic granulocyte colony-stimulating factor. All patients were evaluable for toxicity and 53 for response. Prophylactic granulocyte colony-stimulating factor significantly lowered the incidence of grade III-IV neutropenia and neutropenic fever (p = 0.0001 and 0.01, respectively). The incidence of moderate-severe fluid retention syndrome was lower in patients receiving i.m. dexamethasone (p = 0.08). Overall response rate was 53% (4 complete responses/24 partial responses, 95% confidence interval 39.4-66.2%); 32% have stable disease and 15% progressive disease. In 21 anthracycline-refractory/resistant patients, as well as in 10 paclitaxel-pretreated patients, the overall response rate was 50%. Docetaxel is highly active in anthracycline- and paclitaxel-pretreated metastatic breast cancer, with manageable toxicity. Optimal use of both granulocyte colony-stimulating factor support and steroid premedication deserves further investigation.

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.

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.

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.

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.
