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.

Single-agent epirubicin as primary chemotherapy in T2-T3, N0-N2, M0 breast carcinoma: 6-year follow-up.

OBJECTIVE: Single-agent epirubicin was tested as primary chemotherapy treatment in patients with early breast cancer >3 cm. METHODS: 100 women with locally advanced breast cancer >3 cm were treated with three cycles of single-agent epirubicin at a dose of 120 mg/m2. All patients showing tumor shrinkage to less than 3 cm were considered candidates for conservative surgery (quadrantectomy); in the remaining patients modified radical mastectomy was carried out. Postsurgical treatment consisted of CMF chemotherapy except for postmenopausal node-positive, estrogen-positive patients who were assigned to hormonal treatment with tamoxifen and postmenopausal node-negative, estrogen-positive ones who did not receive any treatment. RESULTS: Quadrantectomy was carried out in 71 patients. At the median follow-up time of 69 months, the relapse rate was 29.6% among patients who underwent quadrantectomy (21 out of 71) and 58.6% among patients who underwent modified radical mastectomy (17 out of 29). CONCLUSIONS: Single-agent chemotherapy with anthracyclines could appear to be an effective treatment in inducing a tumor downstaging in patients with early breast cancer >3 cm. This treatment can be administered outside clinical trials in patients who desire to preserve their body integrity. Further prospective, randomized trials are needed in order to validate and better define the role of epirubicin in the neoadjuvant strategy of breast cancer patients.

Second line therapy with weekly low-dose docetaxel for pretreated non-small-cell lung carcinoma patients: a multicenter Italian phase II study.

Docetaxel is one of the most active drugs in second-line therapy for non-small-cell-lung-carcinoma (NSCLC). The aim of this multicenter study was to evaluate the safety and efficacy of weekly low-dose docetaxel. Forty-two patients with advanced NSCLC pretreated with cisplatinum-based chemotherapy were enrolled. Docetaxel was administered at a dose of 25 mg/m(2) weekly for 12 consecutive weeks. A total of 386 doses were given with a median number of 10 doses per patient (range: 3-12). Treatment showed low incidence of hematologic toxicity and modest non-hematologic toxicity. An episode of grade 4 thrombocytopenia was reported but no episodes of grade 3 or 4 neutropenia. Most frequent non-hematologic toxicities were asthenia and alopecia. Response rate was 10.5% and median survival time (MST) was 12.8 weeks. Weekly treatment with 25 mg/m(2) docetaxel for 12 consecutive weeks appears to be a feasible and active regimen with mild toxicity in heavily pretreated NSCLC patients.

Adjuvant chemotherapy in gastric cancer: 5-year results of a randomised study by the Italian Trials in Medical Oncology (ITMO) Group.

BACKGROUND: The aim of this study was to determine the efficacy of the EAP regimen (etoposide, adriamycin and cisplatin) followed by the Machover schedule (fluorouracil and folinic acid) given as adjuvant treatment to patients with poor prognostic factors (N+ or T3/4). PATIENTS AND METHODS: Before randomisation, the subjects were stratified on the basis of node involvement (N+ or N-) and the time from surgery to randomisation (< or = 21 days or > 22 days). The surgical procedures for sub-total or total gastrectomy with D2 dissection were standardised among the participating centres. RESULTS: Between December 1992 and December 1997, 274 patients were enrolled: 137 in the treatment arm and 137 in the control arm. The majority of the patients (90%) were N+. After a median follow up of 66 months (range 2-83), the 5-year overall survival (OS) was 52% in the treatment arm and 48% in the control arm [hazard ratio (HR) 0.93; 95% confidence interval (CI) 0.65-1.34]; the 5-year disease-free survival (DFS) was 49% and 44%, respectively (HR: 0.83; 95% CI 0.59-1.17). Among the patients with N-/N+ (1-6), the 5-year OS was 61% in the treatment group and 60% in the control group; in those with N+ (1-6), it was 42% and 22%. The treatment was completed by 87% of patients. Drug-related grade 3/4 WHO toxicities included leukopenia (21%), nausea and vomiting (14%), mucositis (9%), neutropenia (3%) and thrombocytopenia (2%). There were two deaths due to sepsis. CONCLUSIONS: Although our results are not statistically significant, there was a limited relative risk reduction in the patients receiving adjuvant therapy (17% in DFS and 7% in OS). The data suggest that D2 surgery may have a favourable impact on OS.

A phase II trial of dacarbazine, fluorouracil and epirubicin in patients with neuroendocrine tumours. A study by the Italian Trials in Medical Oncology (I.T.M.O.) Group.

BACKGROUND: Previous experiences in the treatment of neuroendocrine tumours have demonstrated some activity of single agents such as adriamycin, fluorouracil (FU), streptozotocin and dacarbazine (DTIC). Opinions concerning the usefulness of polychemotherapy in carcinoid tumours are discordant, whereas better results have been achieved in other endocrine pancreatic neoplasms. Based on this background, we used multidrug chemotherapy with DTIC, FU and epirubicin in the treatment of different neuroendocrine tumours. METHODS: The study involved 38 pts with progressive and measurable disease. The treatment schedule was FU 250 mg/m2 i.v., epirubicin 25 mg/m2 i.v., and DTIC 200 mg/m2 i.v. on days 1, 2 and 3 every 3 weeks. RESULTS: The responses achieved by histologic types were carcinoids 2/20, medullary thyroid carcinoma 1/7, neuroendocrine tumours 1/6; and Merkel cell carcinoma 3/5. The median duration of response was 5 months (range 2-11). Stable disease was observed in 13 cases (34%). Out of the 18 cases in progression, 17 had not responded to previous medical treatment. No symptom control was observed in 4 pts with carcinoid syndrome. Treatment toxicity was moderate and included nausea and vomiting, alopecia, leukopenia and mucositis. CONCLUSIONS: Our results document the moderate efficacy of the regimen in all of the histologic types. The major difference in comparison with previous studies was the lower response rate observed in patients with neuroendocrine tumours.
