Dihydropyrimidine dehydrogenase pharmacogenetics for predicting fluoropyrimidine-related toxicity in the randomised, phase III adjuvant TOSCA trial in high-risk colon cancer patients.

BACKGROUND: Dihydropyrimidine dehydrogenase (DPD) catabolises ∼85% of the administered dose of fluoropyrimidines. Functional DPYD gene variants cause reduced/abrogated DPD activity. DPYD variants analysis may help for defining individual patients' risk of fluoropyrimidine-related severe toxicity. METHODS: The TOSCA Italian randomised trial enrolled colon cancer patients for 3 or 6 months of either FOLFOX-4 or XELOX adjuvant chemotherapy. In an ancillary pharmacogenetic study, 10 DPYD variants (*2A rs3918290 G>A, *13 rs55886062 T>G, rs67376798 A>T, *4 rs1801158 G>A, *5 rs1801159 A>G, *6 rs1801160 G>A, *9A rs1801265 T>C, rs2297595 A>G, rs17376848 T>C, and rs75017182 C>G), were retrospectively tested for associations with ⩾grade 3 fluoropyrimidine-related adverse events (FAEs). An association analysis and a time-to-toxicity (TTT) analysis were planned. To adjust for multiple testing, the Benjamini and Hochberg's False Discovery Rate (FDR) procedure was used. RESULTS: FAEs occurred in 194 out of 508 assessable patients (38.2%). In the association analysis, FAEs occurred more frequently in *6 rs1801160 A allele carriers (FDR=0.0083). At multivariate TTT analysis, significant associations were found for *6 rs1801160 A allele carriers (FDR<0.0001), *2A rs3918290 A allele carriers (FDR<0.0001), and rs2297595 GG genotype carriers (FDR=0.0014). Neutropenia was the most common FAEs (28.5%). *6 rs1801160 (FDR<0.0001), and *2A rs3918290 (FDR=0.0004) variant alleles were significantly associated with time to neutropenia. CONCLUSIONS: This study adds evidence on the role of DPYD pharmacogenetics for safety of patients undergoing fluoropyrimidine-based chemotherapy.

Aprepitant versus metoclopramide, both combined with dexamethasone, for the prevention of cisplatin-induced delayed emesis: a randomized, double-blind study.

BACKGROUND: A combination of aprepitant, a 5-HT3 receptor antagonist (r.a.), and dexamethasone is recommended for the prophylaxis of cisplatin-induced nausea and vomiting in the acute phase, and aprepitant + dexamethasone (A + D) in the delayed phase. The aim of this study was to verify if A + D is superior to metoclopramide plus dexamethasone (M + D) in preventing delayed emesis in cancer patients receiving the same prophylaxis for acute emesis. PATIENTS AND METHODS: A randomized double-blind study comparing A + D versus M + D was completed in previously untreated cancer patients. Before chemotherapy, all patients were treated with intravenous palonosetron 0.25 mg and dexamethasone 12 mg, and oral aprepitant 125 mg. On day 2-4, patients randomly received oral dexamethasone 8 mg plus aprepitant 80 mg once daily (days 2-3) or metoclopramide 20 mg four times daily plus dexamethasone 8 mg bid. Primary endpoint was rate of complete response (no vomiting, no rescue treatment) in day 2-5 after chemotherapy. RESULTS: Due to difficulty in the accrual of patients, 303 of the 480 planned patients were enrolled, 284 were fully evaluable, 147 receiving A + D, 137 M + D. Day 1 results were similar in both arms. On day 2-5, complete response rate was not significantly different (80.3% with A + D versus 82.5% with M + D, P < 0.38, respectively), and all secondary endpoints were also similar (complete protection, total control, no vomiting, no nausea, and score of Functional Living Index-Emesis; P < 0.24). Adverse events incidence was not significantly different between the two treatments. CONCLUSIONS: In cancer patients submitted to cisplatin-based chemotherapy, receiving the same antiemetic prophylaxis for acute emesis, A + D is not superior to M + D in preventing delayed emesis, and both treatments present similar toxicity.

Knowledge about cancer screening programmes in Sardinia.

BACKGROUND: High level of attendance by population is considered a proof of the efficacy in the screening programmes. Public health aims to increase people's attendance to cancer screening. The study aimed at assessing the level of knowledge and awareness about screening of citizens in Cagliari, from June to July 2016. METHODS: Recruitment took place near the atrium of the two main shopping centres of the city. The sample included 270 adults (138 men), 18-75 years old (mean age 46 years old). The information gathered from interviews were categorized by dichotomizing answers according to the knowledge and understanding of the discussed topics. Descriptive analysis was performed. The Chi-square test was used to assess gender and educational differences. RESULTS: Results show that population's knowledge of screening is limited. Although the word "screening" is known, only half of the people who declared to have heard of this word know about the aim of screening. Colorectal cancer screening is the least known. Men and people with lower education are less informed than women and those with high education level. CONCLUSION: In order to raise knowledge and awareness about cancer screening, special attention should be paid to communication and to the use of plain language. Future action should highlight the benefit of the screening procedure and thus contributing to spread the cancer prevention culture. Gender and socioeconomic inequalities must be taken into account when planning screening communication campaigns. General practitioner are highly trusted by people. They could play a decisive role to promote screening attendance.

5-year results of cisplatin-epirubicin-vinorelbine (PEV) combination as primary chemotherapy in T2-3, N0-2 breast cancer patients: a multicentre phase II study.

UNLABELLED: The aim this study was to assess the efficacy of cisplatin-epirubicin-vinorelbine, as primary chemotherapy, in reducing the tumour burden in T2-3 N0-2 breast carcinomas. Breast conservative surgery (BCS) rate, clinical and pathological complete response (pCR), toxicity and 5-year disease-free survival (DFS) and overall survival (OS) were evaluated. PATIENTS AND METHODS: Eighty-eight women with tumours > or =2.5 cm were treated with cisplatin (P) 50 mg/m2, epirubicin (E) 100 mg/m2 and vinorelbine (V) 25 mg/m2, every 3 weeks. RESULTS: Fifty-six out of the 88 patients (63.6%) underwent BCS, notably including 12/23 patients with initial tumours >5 cm. The overall clinical response was 72.8% (cCR=11.4%), pCR 20.5% and pTO+pNO 17%. No cardiac toxicity was observed. Grade 3/4 adverse events were leukopenia (9.4%), neutropenia (7.9%), nausea and vomiting (7.3%). After a median follow-up of 5 years, 24 patients (27.3%) had developed local or distant metastases. The mean DFS and OS were 51.7 (SE 2.38) and 57.02 (SE 1.98) months, respectively, and were significantly higher in pCR patients in comparison to the others (63.05 vs. 48.76, p<0.01 and 64.59 vs. 55.04, p<0.05, respectively). CONCLUSION: The PEV regimen was highly effective in reducing the tumour burden, especially for large tumours. The rate of pCR was similar to that obtained by other, including taxane-based regimens, and was well-tolerated. The study demonstrated the feasibility of such a regimen even in small centres, and being of low cost this combination could be of value in the application of primary therapy.

Ifosfamide given by continuous-intravenous infusion in association with vinorelbine in patients with anthracycline-resistant metastatic breast cancer: A phase I-II clinical trial.

BACKGROUND: Vinorelbine (VNR) is highly active in metastatic breast cancer (MBC) and has shown an overall response rate of 40%-50% as first-line treatment. In vitro, a synergy has been observed between this drug and ifosfamide (IFX). In addition, the pharmacokinetics of IFX suggest that it may have greater activity when given by continuous-intravenous infusion (C.I.V.I.). The aim of this study was therefore to assess the antitumor efficacy and toxicity of the combination of bolus VNR and C.I.V.I. IFX as second-line therapy in anthracycline-resistant breast cancer patients. PATIENTS AND METHODS: Forty-two patients with MBC who had already received anthracycline-based chemotherapy were treated with a regimen consisting of IFX, by C.I.V.I. for 72 hours and bolus VNR. The courses were repeated every three weeks for a maximum of eight cycles. Four dose intensification steps were planned. IFX, 1.5 g/m(2) on days 1-3 + VNR, 30 mg/m(2) on day 1 (six patients); IFX, 2 g/m(2) on days 1-3 + VNR, 25 mg/m(2) on day 1 (six patients); IFX, 1.8 g/m(2) on days 1-3 + VNR, 25 mg/m(2) on days 1 and 8 (six patients); IFX, 2 g/m(2) on days 1-3 + VNR, 25 mg/m(2) on days 1 and 8 (24 patients). Sodium-2-mercaptoethane sulfonate (mesna) was associated with IFX at an infusion ratio of 1:1 and, once the infusion was completed, per os every four hours for three times. RESULTS: All of the 42 patients entered were assessable for toxicity, and 41 of them for response. Neutropenia was the most frequently-occurring toxicity, but only five patients at the highest dose level (11.9%) presented grade 4, and none of those at the first three steps. Other significant toxic effects were mild (only grade I-II). The median relative dose intensity was 95% at the highest dose level and all the treatments were administered on an out-patient basis. The overall response rate was 36.5% with a CR rate of 4.8% (two of 41 patients, all at the highest dose level) and a PR rate of 31.7% (13 of 41 patients). The median response duration was 7.0 months (range 2-13 months). CONCLUSIONS: The present phase I-II study shows that the IFX and VNR combination is an active and well-tolerated treatment in MBC and provides an alternative to taxanes for patients previously treated with anthracyclines.

Early detection of the anthracycline-induced cardiotoxicity. A non-invasive haemodynamic study.

Anthracyclines are the most frequent cause of iatrogenic congestive heart failure ranging from acute reversible minor, irreversible reduction in the left ventricular ejection fraction and death despite preventive measures. Sensitive methods are needed to detect earliest preclinical cardiotoxicity along with the development of new protective agents. Thirty breast cancer patients were randomly treated with q 21 120 mg/m2 Epirubicin (EPI) x 3, alone (10 patients), or + ICRF-187 (1000 mg/m2) (10 patients) or + C0Q10 (50 mg/day) (10 patients) and monitored by Thoracic Electrical Bioimpedance (TEB) cardiography before (T0) and at the end of chemotherapy (T1), then at 1, 3, 6 months of follow up (F1, F2, F3). a) The group treated with EPI alone showed, between F1-F2, a significant (p < 0.05) decrease in Stroke Index (S1). Acceleration Index (ACI) and a significant (p < 0.05) increase in Systemic Vascular Resistance Index (SVRI), while between F2 and F3 it showed a significant (p < 0.05) recovery in S1 and ACI. b) The group treated with EPI + ICRF-187 showed, between F1 and F2 a significant decrease in S1 and ACI (p < 0.05, p < 0.01 respectively) and a significant (p < 0.05) increase in SVRI: between F2-F3 ACI had a significant (p < 0.05) recovery: c) The group treated with EPI +C0Q10 showed no modification in Sl, ACI, and SVRI during the study. The ejection Fraction (EF) remained unchanged during the study in all the groups. C0Q10 seems to prevent early decreases in cardiac performance and contractiling, thus avoiding an SVRI increase, while ICRF-187 did not. Since ICRF-187 acts by binding iron, we deem that the earliest cardiac involvement, may occur before iron overload; therefore the role of ICRF-187 and C0Q10 in acute or chronic heart toxicity was correlated with high-dose anthracycline and needs to be further investigated.

Usefulness of pyridinium crosslinks and CA 15-3 as markers in metastatic bone breast carcinoma.

Numerous tumor markers such as CEA, MCA, CA 15-3 have been assayed in breast cancer patients to detect relapse at a preclinical stage and most of all to monitor the treatment of the advanced disease. Since they are not site-specific, pyridinium crosslink dosage has recently been reported as a specific bone resorption marker in several non neoplastic diseases. The aim of this study was to evaluate the urinary pyridinium crosslink levels in breast cancer with or without osseous involvement, and to correlate it with serial doses of CA 15-3. 285 breast cancer patients (226 free of disease and 59 with bone metastases) were measured for both pyridinoline and CA 15-3. In the metastatic patients the mean values of the two markers were significantly higher than in non evident disease patients (P = < 0.01 and p = < 0.001 respectively). Abnormal values over the normal were found in 22% for pyridinoline and 11% for CA 15-3 in patients free of disease while the normal values observed in patients with bone metastases were 22% for pyridinoline and 39% for CA 15-3. Tandem dosage of CA 15-3, was highly sensitive but site-aspecific, and pyridinoline, which is bone specific, may be useful chiefly in the monitoring of breast cancer treatment, since many physiological conditions such as age, menopausal status and variation over 24 hours, and cost effectiveness will influence the use of pyridinoline during follow-up.

A phase II study of gemcitabine and tamoxifen in advanced pancreatic cancer.

BACKGROUND: Advanced pancreatic cancer (APC) constitutes a poor-prognosis disease with few and disappointing therapeutic options. In recent years chemotherapy has demonstrated a positive effect on disease-related symptoms with the introduction of a novel pyrimidine analogue, gemcitabine. Moreover there is experimental and clinical evidence that endocrine therapy may play a small but unexplored role in the management of APC. Therefore we performed a phase II study to assess whether the combination of gemcitabine and tamoxifen could be an active and safe schedule for the treatment of APC in terms of response rate and clinical benefits. MATERIALS AND METHODS: Twenty-seven evaluable consecutive patients with locally advanced, unresectable or metastatic adenocarcinoma of the pancreas were treated with gemcitabine (1000 mg/mq given as a short infusion once weekly for 3 consecutive weeks out of every 4 weeks) and tamoxifen (20 mg daily starting the second day after gemcitabine). The treatment was continued until progression or unacceptable toxicity. Evaluation of efficacy included response rate, time to progression, survival and clinical benefit, an integrated measurement of pain parameters, weight and performance status. RESULTS: A partial response was achieved in 11% of patients while 48% experienced stable disease, lasting at least 8 weeks; disease progression was documented in 41% of patients. The median time of progression was 4.5 months; the median survival-time was 8 months and one-year survival was 31%. Clinical benefit was documented in 59% of patients with a median duration of 13 weeks. No gastrointestinal or haematological grade 4 toxicity was observed. In general the treatment showed a satisfactory safety profile and tamoxifen-related toxicity was not documented. CONCLUSION: The combination of gemcitabine and tamoxifen appears to be an innovative therapeutic approach in the management of APC with interesting clinical activity and a good profile of toxicity. This novel schedule of treatment deserves further investigation in large randomized trials to assess if the addition of tamoxifen could improve the therapeutic results of gemcitabine in APC, mostly in term of quality of lfe.

Prevention of delayed emesis by a single intravenous bolus dose of 5-HT3-receptor-antagonist in moderately emetogenic chemotherapy.

While the use of 5-HT3 receptor antagonists is clearly justified in patients receiving cisplatin, their role with less emetic drugs is still not defined. The aim of our randomized study was to verify the efficacy of the single standard dose of three 5-HT3-receptor-antagonists in moderately emetic chemotherapies. Sixty chemotherapy-naive breast cancer patients of 30 to 71 years in age, P.S. = 0-1, receiving 5-fluorouracil-epirubicin-cyclophosphamide (FEC 75) q 21 days or cyclophosphamide-methotrexate-5-fluorouracil (CMF) or 120 mg/m2 epirubicin or high dose mitomycin-methotrexate-mitoxantrone (MMM) q 14 days (+ G-CSF) or 100 mg/m2 epirubicin (+ G-CSF) were randomized to receive, 15 min before chemotherapy, 8 mg i.v. bolus of ondansetron or 3 mg i.v. granisetron or 5 mg i.v. tropisetron and no further antiemetic therapy in the following days. 180 cycles were evaluable. Complete protection, (the absence of vomiting episodes,) was respectively 75%, 70% and 70% in the acute and 70%, 82%, 72% in the delayed phases, and an absence of nausea was 56%, 37% and 20% in the acute phase and 50%, 35% and 27% in the delayed, respectively. Complete response, (absence of vomiting and absence or mild nausea,) was 74%, 58.6% and 50.8% in the acute and 64%, 63.7%, 47.3% in the delayed phases, respectively. At the statistical analysis no significant differences between the three drugs were found regarding acute vomiting while ondansetron was superior to granisetron and tropisetron in acute (p = 0.018; p < 0.05) and delayed nausea (P = 0.104; p < 0.01). This activity is practically the same as that we reported (Ann Oncol 1994; 6, suppl 8: 204) with a loading dose on day 1 and maintenance for the following 2-5 days, but with a significantly favorable cost-benefit ratio.

Is there a role for adjuvant immunochemotherapy after radical nephrectomy in pT2-3N0M0 renal cell carcinoma?

Five-year overall survival after radical surgery in N0M0 renal cell carcinoma varies from 45-80% in pT2 to 35-50% in pT3 categories. In view of the alpha interferon and vinblastine combination which has shown some activity in advanced disease with increasing efficacy in limited metastatic invasion, we decided to explore the theoretical advantage of adjuvant chemo-immunotherapy in radically resected stage II, III renal cell carcinoma. A single-institution phase II study was undertaken to evaluate the efficacy and tolerability of alpha 2a-interferon (alpha 2a-INF) in combination with vinblastine in 30 patients with pT2-T3 N0M0 renal cell carcinoma (RCC). Thirty-two patients who received only radical nephrectomy and extended lymphadenectomy were analyzed and results were compared with the first group. Twenty-three of 30 (76.6%) patients in the first group are alive with no evidence of disease. The median follow-up for the 23 patients still alive was 67 months (range 60 to 72). Metastases were documented in 5 patients (16.6%) with a median interval to progression of 24 months. Four of them (13.6%) died of tumor. In the control group, 16 out of 32 patients (50%) are still alive, with a median follow-up for the patients still alive of 62 months (range 60 to 68). Fifteen patients developed distant metastases and 2 of them had a local recurrence. All of them (46.8%) died of tumor. Median progression interval was 24 months. After stratification by pathological grade, site, laterality and number of nodes found at lymphadenectomy there were no statistical differences in risk of progression or death in the two groups.(ABSTRACT TRUNCATED AT 250 WORDS)

5-fluorouracil plus folinic acid with or without ifosfamide in advanced colorectal cancer: a phase II randomized trial.

AIM: This phase II trial evaluated the biomodulation of 5-fluorouracil (5-FU) plus folinic acid (FA) with or without ifosfamide (IFO) in chemotherapy-naive patients with colorectal cancer. PATIENTS AND METHODS: Forty-eight patients were randomized to receive: FA (25 mg/m2 iv bolus days 1 to 3), followed by 5-FU (750 mg/m2 iv bolus days 1 to 3), arm A; or FA (25 mg/m2 iv bolus days 1 to 3), followed by 5-FU (750 mg/m2 iv bolus days 1 to 3) plus IFO (2,000 mg/m2 in 1000 mL 5% dextrose in a 2-hr infusion, days 1 to 3), arm B. Mesna was added during and after IFO to prevent hemorrhagic cystitis. Treatment was repeated every 21 days in both arms. RESULTS: Forty-five patients were assessable for response: in arm A, 5 patients achieved a partial response (overall response, 25%), and in arm B, 2 patients achieved a complete and 1 a partial response (overall response, 12%). Time to failure was 3.5 months (range, 1-38) in patients treated with 5-FU plus FA, and 3 months (range, 1-21) in patients treated with the IFO combination. The median survival time was 13.5 months (range, 1-49 months) in arm A and 16 months (range, 1-43 months) in arm B. Diarrhea, stomatitis and vomiting were the most common nonhematologic toxicities in both arms. The most notable hematologic toxicity was leukopenia; 15% and 20% of patients experienced grade 4 in arm A and arm B, respectively. CONCLUSIONS: IFO does not increase the activity of the 5-FU plus FA combination in advanced colorectal cancer.

[Evaluation of quality of life in oncology. Rationale and objectives of the first phase of the Quality of Life in Oncology project]. / La valutazione della qualità di vita in oncologia. Razionale ed obiettivi della prima fase del progetto QvOnc.

Although the subjective nature of quality of life perception is generally accepted, less attention has been paid to the procedure of selecting domains to be explored with questionnaires. In most cases domains are selected by panel of experts. It is not known whether these domains are relevant for the patients. Moreover, questionnaires developed in 'foreign' countries may not be culturally sound or relevant for patients living in different cultural background. In order to explore what really contributes to quality of life of Italian patients, a survey was conducted with the aim of identifying any dimension of quality of life, positively or negatively impacted on from the illness and therapies. A sample of two hundred and eighty eight cancer patients with previously specified characteristics (primary tumor, stage of disease and place of residence) were identified. After consenting to partecipate to the study, a staff member (a physician, a nurse or a psychologist) asked the patient to complete an open-ended questionnaire in the out-patient clinic or at home. This questionnaire, partially derived from a study by Padilla et al. made up of 5 questions: 'What does the term quality of life mean to you?', 'What contributes to a good quality of life?', 'What contributes to a poor or bad quality of life?', 'Which either physical or psychological symptom interferes with your quality of life?', 'State any positive or negative change in your quality of life, due to illness or treatments'. The first question was asked to explore the meaning of quality of life for the patient; the second and third question were asked to determine the contents of quality of life not health related; the fourth question and the diary provided information about quality of life contents related to his own experience of disease. Two hundred and forty eight questionnaires (86.1%) were obtained from 7 Cancer Centres participating to the study (Genova, Milano, Roma, Perugia, Napoli, Cagliari, Palermo). All the questionnaires were transcribed and subsequently broken down in phrases on a form that allowed coding. Three raters (a research nurse, an oncologist and a clinical psychologist) made the content analysis using as conceptual framework the list of domains identified by the Italian Society of Psycho-Oncology. The present study shows the possibility to define the content domain of quality of life attributes for cancer patients, using patients as experts.

Nestin expression associates with poor prognosis and triple negative phenotype in locally advanced (T4) breast cancer.

Nestin, an intermediate filament protein, has traditionally been noted for its importance as a neural stem cell marker. However, in recent years, expression of nestin has shown to be associated with general proliferation of progenitor cell populations within neoplasms. There is no reported study addressing nestin expression in T4 breast cancer patients. Thus, the aim of the present study was to investigate, through immunohistochemistry, the expression and distribution of nestin in T4 breast cancer, in order to determine its association with clinical and pathological parameters as well as with patients' outcome. Nestin was detectable in tumoral cells and in endothelial cells of blood microvessels, and it is significantly expressed in triple-negative and in inflammatory breast cancer (IBC) subgroups of T4 breast tumours. The Kaplan-Meier analysis showed that the presence of nestin in tumoral cells significantly predicted poor prognosis at 5-years survival (P=0.02) and with borderline significance at 10-years of survival (P=0.05) in T4 breast cancer patients. On the basis of these observations, we speculate that nestin expression may characterize tumours with an aggressive clinical behavior, suggesting that the presence of nestin in tumoral cells and vessels may be considered an important factor that leads to a poor prognosis. Further studies are awaited to define the biological role of nestin in the etiology of these subgroups of breast cancers.

Ifosfamide given by continuous-intravenous infusion in association with vinorelbine in patients with anthracycline-resistant metastatic breast cancer: a phase I-II clinical trial.

BACKGROUND: Vinorelbine (VNR) is highly active in metastatic breast cancer (MBC) and has shown an overall response rate of 40%-50% as first-line treatment. In vitro, a synergy has been observed between this drug and ifosfamide (IFX). In addition, the pharmacokinetics of IFX suggest that it may have greater activity when given by continuous-intravenous infusion (c.i.v.i.). The aim of this study was, therefore, to assess the antitumor efficacy and toxicity of the combination of bolus VNR and c.i.v.i. IFX as second-line therapy in anthracycline-resistant breast cancer patients. PATIENTS AND METHODS: Forty-two patients with MBC who had already received anthracycline-based chemotherapy were treated with a regimen consisting of IFX, by c.i.v.i. for 72 hours and bolus VNR. The courses were repeated every three weeks for a maximum of eight cycles. Four dose intensification steps were planned: IFX, 1.5 g/m2 on days 1-3 + VNR, 30 mg/m2 on day 1 (six patients); IFX, 2 g/m2 on days 1-3 + VNR, 25 mg/m2 on day 1 (six patients); IFX, 1.8 mg/m2 on days 1-3 + VNR, 25 mg/m2 on days 1 and 8 (six patients); IFX, 2 g/m2 on days 1-3 + VNR, 25 mg/m2 on days 1 and 8 (24 patients). Sodium-2-mercaptoethane sulfonate (mesna) was associated with IFX at an infusion ratio of 1:1 and, once the infusion was completed, per os every four hours for three times. RESULTS: All of the 42 patients entered were assessable for toxicity, and 41 of them for response. Neutropenia was the most frequently-occurring toxicity, but only five patients at the highest dose level (11.9%) presented grade 4, and none of those at the first three steps. Other significant toxic effects were mild (only grade I-II). The median relative dose intensity was 95% at the highest dose level and all of the treatments were administered on an out-patient basis. The overall response rate was 36.5% with a CR rate of 4.8% (two of 41 patients, all at the highest dose level) and a PR rate of 31.7% (13 of 41 patients). The median response duration was 7.0 months (range 2-13 months). CONCLUSIONS: The present phase I-II study shows that the IFX and VNR combination is an active and well-tolerated treatment in MBC and provides an alternative to taxanes for patients previously treated with anthracyclines.

Ethinyl estradiol and medroxyprogesterone treatment in advanced breast cancer: a pilot study.

Twenty patients with disseminated breast cancer unresponsive to conventional chemotherapy and chemohormonotherapy were treated with an alternating sequential schedule of ethinyl estradiol and medroxyprogesterone on the basis of correlations between hormones and estrogen and progestin receptors. Of 19 evaluable patients, six underwent partial or complete remission, while five others showed minor responses.

PIP: A pilot study was conducted on 20 patients with disseminated breast cancer previously unresponsive to conventional chemotherapy and chemohormonotherapy. The 20 women were treated with ethinyl estradiol orally on days 1 and 2, medroxyprogesterone on days 3-9. After a 2-day interval, the sequential cycle was repeated. 10% of the women had complete remission and 20% more had partial remissions. More than 1/4 had minor remissions and 10% had their disease stabilized. Side effects with the therapy were practically absent. The rationale for the sequential therapy was suggested by interactions among hormones and receptors and the priming activity of estrogens on progesterone receptors. These preliminary results indicate that an alternated sequential therapy of ethinyl estradiol and medroxyprogesterone may be useful in managing advanced cancer.

Cancer patients as 'experts' in defining quality of life domains. A multicentre survey by the Italian Group for the Evaluation of Outcomes in Oncology (IGEO).

Although the subjective nature of quality of life is generally accepted, less attention has been paid to the procedure of selecting domains to be explored with questionnaires. To explore what contributes to cancer patients' quality of life, a survey was conducted with the aim of identifying contents of quality of life using cancer patients as 'experts'. A questionnaire with open-ended items aimed at exploring the meaning of quality of life and at determining the contents of health and not health related quality of life, was submitted to a sample of cancer patients stratified by residence, cancer site and stage of disease. The 248 questionnaires received were transcribed and broken down into phrases to allow coding. A content analysis was performed, using as a conceptual framework, the domains identified by the Italian Society of Psycho-Oncology. Overall, 43 domains and a list of symptoms were identified. The two most frequently reported symptoms were pain (21.4% patients) and fatigue (14.1% patients). Social relationships and psychological domains were heavily represented. Twenty sub-domains related to the domain 'psychological well-being'. This study suggests that information on the content of quality of life questionnaires to be submitted to people affected by a specific disease, should be derived by studying people suffering the specific disease. These results reinforce the criticism that available quality of life instruments are more likely to reflect the perspective of health professionals than patients.
