RESUMEN

From February 1983 to January 1985, 497 patients with advanced breast cancer were randomly allocated to receive either epirubicin or doxorubicin in the following combination chemotherapy regimen: fluorouracil (5-FU) 500 mg/m2 intravenous (IV) on days 1 and 8; epirubicin or doxorubicin 50 mg/m2 IV on day 1; cyclophosphamide 500 mg/m2 IV on day 1 (FEC or FAC). Cycles were repeated every 21 days until progression or to cumulative doses of 700 mg/m2 for epirubicin and 550 mg/m2 for doxorubicin. Dose reductions were applied according to the standard criteria. Activity was evaluated in 443 patients (222 in the FEC arm and 221 in the FAC arm). The two experimental groups were comparable in age, performance status, menopausal status, histology, previous treatments, and site of the disease. The overall response rate (complete response and partial response [CR + PR]) was not significantly different: 53.6% for FEC and 56.5% for FAC. The median time to progression was 273 days for FEC and 314 days for FAC; the median survival time was 591 and 613 days, respectively. Leukopenia, anemia, nausea, and vomiting were significantly lower in patients treated with FEC. As for cardiotoxicity, four cases of congestive heart failure (CHF) were recorded among patients treated with FAC while only one was observed in the FEC group. These results indicate that epirubicin in a combination chemotherapy regimen is as active as doxorubicin and is significantly less toxic.

RESUMEN

Anaplastic thyroid carcinoma is a rare disease with a poor prognosis. Surgery represents the curative treatment for limiting the disease. In the presence of locoregional disease, not suitable for surgery, and for metastastic disease, chemotherapy represents the treatment option. Single agents chemotherapy can produce some responses; doxorubicin is an active drug with a rate of partial response lower than 20%. Association with cisplatin seems to be more active producing a higher rate of complete responses. Liposomal doxorubicin is a new class of anthracyclines, derived from a structural modification of doxorubicin, representing a new form of an old drug with pharmacological characteristics that facilitate a more easy elusion from immune system, a longer half-life, an increased tumor cell uptake and a reduced toxicity if compared with parental drug. Herein we report the first case of an anaplastic thyroid carcinoma treated with the use of liposomal doxorubicin. The encouraging response observed with single agent liposomal doxorubicin (70% according to RECIST criteria) deserves further investigations.

RESUMEN

The aim of the study was to describe in detail the impact of aging and comorbidities on safety and efficacy of gemcitabine-cisplatin in the subset of elderly with advanced NSCLC. We report the results of our study which enrolled patients aged over 65 years or older. This study included 46 patients consecutively admitted to our Department. Treatment consisted of gemcitabine 1250 mg/m2 on days 1 and 8, and cisplatin 75 mg/m2 on day 2, of a 21-day cycle. The Charlson score method was chosen to evaluate the conditions of comorbidity. All patients were evaluable for toxicity and 44 for activity. A total of 128 courses were administered, with a median of 3 courses per patient and a dose-intensity of 93% and 88% for gemcitabine and cisplatin, respectively. Grade 3-4 neutropenia (22% of patients) and grade 3 asthenia (4.5%), emesis (4.5%) and nephrotoxicity (4.5%) were the most severe adverse events. Univariate analysis of toxicity did not show any significant difference among all groups. The overall response rate was 45.6% (95% CI, 31.3-60). At a median follow up of 13 months, the median and progression-free survival were 15 and 8 months, respectively. The multivariate analysis resulted in objective response and disease control being predictive of longer survival. The combination of gemcitabine and cisplatin appears to be an effective and tolerated regimen for elderly patients with advanced NSCLC, regardless of aging and condition of comorbidities. Prospective randomized trials based on specific geriatric assessment are required to obtain compelling information for the optimal management of elderly patients with advanced NSCLC.

RESUMEN

Twenty-two patients with advanced malignancies were treated with low-dose cytosine arabinoside (ara-C) (45 mg/m2 sc every 12 h for 3 days) and cisplatin (DDP) (100 mg/m2 ev on day 2, 2 h after ara-C. Patients received 61 cycles of ara-C + DDP with a median number per patient of 2.7 cycles (range, 1-5). All patients were evaluable for toxicity and response. Overall, 6 of 22 patients (27%) obtained an objective response (2 CR + 4 PR) with a median response duration of 20 weeks. Hematologic and gastrointestinal toxicities were moderate. Our results show a low response rate with the ara-C and DDP combination compared to the interesting results obtained in vitro.

RESUMEN

The utility of fine needle aspiration biopsy (FNAB) was checked in the diagnosis of 187 neoformations which arose in the same number of patients during follow-up after treatment for malignant neoplasia. FNAB diagnosis was 138 malignant lesions (9 primary and 129 secondary) and 49 benign lesions (8 neoplastic and 41 nonneoplastic). 157 of the 187 diagnoses (83.95%) were controlled: 124 histologically (78.98%) and 33 clinically (21.01%). Specificity was 100%, sensitivity 98.36%, predictive negative value 94.59% and total diagnostic efficiency 98.72%. The reliability of the method and the usefulness of the findings from the therapeutic point of view suggest the advisability of performing FNAB during the post-diagnostic phase of neoplastic disease.

RESUMEN

Twenty-three patients with advanced colorectal cancer were treated with folinic acid (200 mg/m2/day 1-5 IV bolus injection) and 5-fluorouracil (400 mg/m2/day 1-5 IV in 15 minutes) every 28 days. Only three patients were pretreated. Objective response was observed in 6 (30%) of 20 evaluable patients (three complete and three partial responses). The median duration of response was 9 months (range 5-15) and time to disease progression ranged from 2 to 12 months (median 6 months). Median survival was 21 months (range 12-23+) for responders. Another 6 (30%) patients had stabilization of disease. Toxicity was generally gastrointestinal (mucositis, diarrhea, nausea); moderate leukopenia was noted. The response rate found in this study indicates that folinic acid administered in high doses enhances the effectiveness of 5-FU administered concomitantly in colorectal cancer.
