Phase II study of sequential hormonal therapy with anastrozole/exemestane in advanced and metastatic breast cancer.

Hormonal therapy is the preferred systemic treatment for recurrent or metastatic, post-menopausal hormone-receptor-positive breast cancer. Previous studies have shown that there is no cross-resistance between exemestane and reversible aromatase inhibitors. Exposure to hormonal therapy does not hamper later response to chemotherapy. Patients with locally advanced or metastatic, hormonal receptor positive or unknown, breast cancer were treated with oral anastrozole, until disease progression, followed by oral exemestane until new evidence of disease progression. The primary end point of the study was clinical benefit, defined as the sum of complete responses (CR), partial responses (PR) and > 24 weeks stable disease (SD). In all, 100 patients were enrolled in the study. Anastrozole produced eight CR and 19 PR for an overall response rate of 27% (95% CI: 18.6-36.8%). An additional 46 patients had long-term (> 24 weeks) SD for an overall clinical benefit of 73% (95% CI: 63.2-81.4). Median time to progression (TTP) was 11 months (95% CI: 10-12). A total of 50 patients were evaluated for the second-line treatment: exemestane produced one CR and three PR; 25 patients had SD which lasted > or = 6 months in 18 patients. Median TTP was 5 months. Toxicity of treatment was low. Our study confirms that treatment with sequential hormonal agents can extend the period of time during which endocrine therapy can be used, thereby deferring the decision to use chemotherapy.

5-Fluorouracil and folinic acid with or without CPT-11 in advanced colorectal cancer patients: a multicenter randomised phase II study of the Southern Italy Oncology Group.

PURPOSE: The combination regimen CPT-11 plus bolus and infusion 5-fluorouracil (5-FU) with high-dose leucovorin (hybrid regimen LV5FU2) has been tested for activity and toxicity against advanced colorectal carcinoma in a randomised, multicenter phase II trial. PATIENTS AND METHODS: A total of 102 chemotherapy-naïve patients were randomised in a 1:2 fashion to receive: leucovorin 100 mg/m2 administered as a two-hour infusion before 5-FU 400 mg/m2 as an intravenous bolus, and FU 600 mg/m2 as a 22-hour infusion immediately after 5-FU bolus injection repeated on days 1 and 2 (LV5FU2 regimen, arm A, 34 patients) or CPT-11 at 180 mg/m2 (150 mg/m2 for patients of age > or = 70 and < 75 years) only on day 1 immediately before LV5FU2 therapy (LV5FU2 + CPT-11 regimen, arm B 68 patients). Both treatments were repeated every two weeks. The presence of a calibration arm assured consistency and more realistic evaluation of results achieved with the LV5FU2 + CTP-II regimen. RESULTS: Thirty-three and sixty-four patients were evaluable in arm A and B, respectively. The overall response rate was 18% in arm A (95% CI: 7%-34%) and 40% in arm B (95% CI: 28%-52%). Median time to progression, median duration of response and survival were similar in both groups. Responders (CR + PR) survived statistically longer than non-responders only in arm B (20 vs. 10 months, P = 0.0016). All patients were evaluable for toxicity which was mild in both groups; gastrointestinal disturbances were the most common. There were no treatment-related deaths. Grade 3-4 toxicity was uncommon in both arms. CONCLUSIONS: The addition of CPT-11 to the hybrid LV5FU2 regimen provided a significant overall response rate (40%) with relatively mild toxicity. The overall response rate was 18% in patients treated with LV5FU2 alone in the calibration arm. Thus, considering other encouraging data from the literature, the CPT-11 + FU-LV combination therapy can be regarded as a new, very effective treatment option for first-line treatment of advanced colorectal cancer patients.

Amifostine plus cisplatin plus vinorelbine in the treatment of advanced non small cell lung cancer: a multicenter phase II study.

PURPOSE: to evaluate the activity and toxicity of the combination cisplatin plus vinorelbine plus amifostine in advanced non small cell lung cancer (NSCLC). PATIENTS AND METHODS: a two-stage Simon design was applied. To proceed after the first stage, responses from seven of 19 patients were needed. Overall, 17 responses from 40 treated patients were required to comply with the design parameter. Inclusion criteria were cyto-histologically proven stage IIIB-IV NSCLC; age of 70 years or less; Eastern Cooperative Oncology Group (ECOG) performance status of 2 or less; normal cardiac, hepatic, renal and bone marrow functions; and no previous chemotherapy. Patients were staged by physical examination, biochemistry, chest radiograph, brain, thoracic and abdominal computed tomographic (CT) scans, and bone scan. All patients received cisplatin 100 mg/m(2) intravenously (iv) day 1, vinorelbine 25 mg/m(2) iv days 1-8-15-22, amifostine 740 mg/m(2) iv day 1 every 4 weeks up to six cycles. Eleven of 40 enrolled patients were stage IIIB and 29 stage IV, with a median age of 57 years (range, 38-70 years). RESULTS: all patients were evaluable for response and toxicity (intention to treat analysis). We observed 20 (50%) objective responses, with four (10%) complete responses. Median time to progression was 20 weeks, and median survival was 45 weeks. The toxicity was manageable. The reported main toxicities were neutropenia grade 4 in 10% of patients, grade 1 and grade 3 nephrotoxicity both in 5% of patients and grade 1 amifostine-related hypotension in 15% of patients. CONCLUSION: these data show that cisplatin plus vinorelbine plus amifostine is an active and feaseable regimen in stage IIIB-IV NSCLC. A phase III trial comparing cisplatin plus vinorelbine versus cisplatin plus vinorelbine plus amifostine in advanced NSCLC is warranted.

A multicentre, double-blind, randomised trial comparing ondansetron versus ondansetron plus dexamethasone in the prophylaxis of cisplatin-induced delayed emesis.

The aim was to compare the efficacy of ondansetron and a combination of ondansetron plus dexamethasone in the prophylaxis of cisplatin-induced delayed emesis over three consecutive courses of chemotherapy. Cancer patients scheduled to receive for the first time cisplatin (>50 mg/m(2)) in combination with other cytotoxic agents, were recruited in a multicentre, randomised, double-blind study and treated with ondansetron 8 mg i.v. and dexamethasone 20 mg i.v. Twenty-four hours after the start of chemotherapy, patients were randomised to treatment either with oral ondansetron 8 mg bd plus placebo on days 2-5 (group A) or with oral ondansetron 8 mg bd plus oral dexamethasone 8 mg bd on days 2-3, and 4 mg bd on days 4 and 5 (group B). Two hundred and thirty-six cancer patients were recruited into the study. Complete protection from delayed vomiting/nausea in group A and group B was Obtained in 50/39% and in 63/42% of patients, respectively in the first course; in 55/34% and in 64/40% in the second and in 49/31% and 60/37% in the third. Logistic regression analysis reveals a statistically significant difference in incidence of emesis between the combination of ondansetron plus dexamethasone and ondansetron alone (P<0.05). The same model, however, shows no difference in incidence of nausea between the two treatment regimens. Ondansetron plus dexamethasone reduces the risk of delayed emesis following cisplatin chemotherapy as compared to ondansetron alone.

Carboplatin, epirubicin, and VP-16 chemotherapy in the treatment of small cell lung cancer.

In our study, 72 SCLC patients, 23 with limited and 49 with extensive disease, were treated with carboplatin, epirubicin, and VP-16 (CEV) chemotherapy (CBDCA 300 mg/m2 day 1, EDX 50 mg/m2 day 1, VP-16 100 mg/m2 i.v. days 1-3, every 4 weeks). Patients with limited disease were also subjected to concurrent "split-course" chest radiotherapy followed by surgery in responders if they were not staged IIIB at diagnosis. In limited disease we obtained 96.5% objective responses (OR) with 52.5% complete responses (CR), a median survival of 14 months, with 13% long-term survivors at 30 months. In extensive disease we obtained 83.6% OR with 28.5% CR, and a median survival of 10 months. Toxicity consisted mainly of manageable myelosuppression, especially for limited disease. These data show high activity of CEV chemotherapeutic regimen.

[Personality profile of cancer patients under ambulatory chemotherapeutic treatment]. / Il profilo della personalità nell'ammalato neoplastico in trattamento chemioterapico ambulatoriale.

The MMPI questionnaire was used as a personality test on 20 painfree cancer patients, otherwise in good health and undergoing outpatient chemotherapy. Analysis of the data shows that even in an early stage cancer can produce significant alterations in personality. 85% of the patients studied had emotional disorders with hypochondria and depression being the psychopathological profiles most commonly observed.
