Abstract
The EORTC Breast Cancer Cooperative Group carried out a randomized trial to compare doxorubicin with epirubicin as second-line chemotherapy in patients with metastatic breast cancer. Two hundred and fifty-nine patients with at least one site of metastatic disease entered this trial, of whom 232 patients were eligible. Treatment consisted of doxorubicin 75 mg m(-2) or epirubicin 90 mg m(-2) i.v. every 3 weeks. The overall response rates for doxorubicin and epirubicin were 36% and 28% respectively (P = 0.173). The median time to progression was 23 weeks for doxorubicin and 19 weeks for epirubicin (P = 0.063) and the median duration of response was 40 weeks for doxorubicin and 32 weeks for epirubicin (P = 0.059). The median survival was 47 weeks for doxorubicin and 44 weeks for epirubicin (P = 0.196). Leucocyte count on retreatment day (P = 0.011) and platelet nadir (P = 0.031) were significantly lower in the doxorubicin-treated group. Also mucositis (P < 0.001), diarrhoea (P = 0.005) and haemorrhage (P = 0.048) were significantly worse in the doxorubicin arm. Nine patients on doxorubicin and two patients on epirubicin experienced congestive heart failure (CHF). At the dose levels used in this study, no statistical differences in response rate and survival were found between the two treatment arms. Treatment with doxorubicin tended to result in a slightly longer duration of response and time to progression but doxorubicin was more toxic than epirubicin.

Abstract
BACKGROUND Fine-needle aspiration (FNA) biopsy has been used increasingly in the diagnosis and biologic characterization of breast carcinomas in patients who receive preoperative chemotherapy. Because proliferative activity of breast carcinoma has been shown to be of prognostic significance, the authors compared immunocytochemical Ki-67 growth fraction and flow cytometric S-phase fraction (SPF), both evaluated on FNA samples. METHODS The proliferative activity of 134 FNA samples from primary breast carcinoma patients was studied using both immunocytochemistry with the monoclonal antibody Ki-67 and SPF determined by DNA flow cytometry. RESULTS Ki-67 and SPF were evaluable in 114 and 107 cases, respectively, and both were evaluable in 95 cases. Of the 134 FNA samples studied, 37% were diploid and 63% were aneuploid. The distribution of both Ki-67 and SPF was different in diploid and aneuploid tumors. The median Ki-67 value as well as the median SPF were significantly higher in aneuploid versus diploid tumors (P < 0.001). Median Ki-67 and SPF values were used to discriminate between low versus high proliferating tumors. The overall concordance between Ki-67 and SPF was 75% (P < 0.001). A good correlation was found between Ki-67 and SPF (correlation coefficient = 0.72; P < 0.001). CONCLUSIONS The results of the current study suggest that Ki-67 growth fraction and SPF determined by FNA may be used as measurements of the proliferative activity of breast carcinoma. The authors recommend these determinations be used as preoperative procedures in patients with a cytologic diagnosis of breast carcinoma who are candidates for neoadjuvant chemotherapy and/or endocrine therapy.

Abstract
PURPOSE To compare, in a double-blind, placebo-controlled, randomized trial, the efficacy of two different doses of the depot formulation of adrenocorticotropic hormone (ACTH) in controlling delayed emesis after cisplatin. PATIENTS AND METHODS One hundred fifty-two patients were enrolled onto the study. On day 1, all patients received cisplatin (60 to 120 mg/m2) and a combination of dexamethasone 20 mg plus ondansetron or metoclopramide to prevent acute emesis. On day 2 (24 hours after cisplatin administration), patients were randomized to receive placebo, or ACTH 1 mg intramuscularly (I.M.), or ACTH 2 mg I.M. plus one additional dose of 1 mg on day 4. Details of vomiting, nausea, and adverse effects were recorded daily for every 24-hour period from day 2 to day 6. In a subset of patients, serum cortisol levels were measured between 20 and 72 hours after cisplatin administration. RESULTS One hundred fifty patients were assessable. Over the 5 days of the study, delayed vomiting occurred less frequently in the patients treated with ACTH 2 mg plus 1 mg than in those treated with ACTH 1 mg or placebo (28%, 38%, and 65%, respectively; P = .001). The greatest observed differences were seen on days 2 (24 to 48 hours; P = .01) and 3 (48 to 72 hours; P = .01). On days 4, 5, and 6 (96 to 144 hours), no significant differences were observed among the three arms. The severity of delayed emesis expressed as the mean number of emetic episodes per day was 0.48, 0.70, and 0.80, respectively (P = .002). Patients treated with the higher dose of ACTH had the least nausea on day 3 (P = .02) and day 4 (P = .03). Adrenal cortisol secretion rapidly increased after ACTH injection, but was suppressed for approximately 44 hours in the placebo group. Toxicity was mild and transient in all groups. CONCLUSION ACTH reduces the incidence and severity of delayed vomiting and nausea after cisplatin. A dose of 2 mg 24 hours after cisplatin is better than one of 1 mg. Whether the activity of ACTH is mediated only by adrenal corticosteroids needs to be verified.

Abstract
Fine-needle aspiration (FNA) biopsy is increasingly used in the diagnosis and biological characterization of breast carcinomas in patients who receive preoperative chemotherapy. In this context, nuclear cytologic grade supplemented by DNA content could play an important role in the morphologic assessment of breast cancer. In this study, DNA ploidy pattern, analyzed by flow cytometry on FNAs from 92 primary breast carcinomas, was related to cytologic nuclear grade. Twenty-seven samples were cytologic grade 1, 33 were grade 2, and 32 were grade 3. Ploidy correlated with cytologic nuclear grade (P = 0.0001). Thirty percent of grade 1, 55% of grade 2, and 84% of grade 3 tumors were DNA aneuploid. For 30 of the 92 FNAs, it was possible to compare nuclear cytologic grade with the corresponding histologic grade using the Scarff, Bloom, and Richardson system. A high concordance (80%) between nuclear grade on FNAs and histologic grade was found. DNA flow cytometry in combination with nuclear cytologic grade might represent additional information for the characterization of breast cancer diagnosed by FNA.

Abstract
BACKGROUND In a randomized Phase II study, the authors evaluated the activity and toxicity of the new cisplatin, doxorubicin, and mitomycin C (PAM) combination, that includes cisplatin (P) instead of 5-fluorouracil as in the 5-fluorouracil, doxorubicin, and mitomycin C (FAM) combination, in patients with advanced gastric carcinoma. FAM was utilized as a control treatment arm. METHODS Fifty eligible patients were assigned to the FAM (5-fluorouracil 600 mg/m2 intravenous (i.v.) on Days 1, 8, 29, 36; doxorubicin 30 mg/m2 i.v. on Days 1 and 29; mitomycin C 10 mg/m2 i.v. on Day 1; every 8 weeks) and 52 to the PAM combination (cisplatin 60 mg/m2 i.v. on Days 1 and 29; doxorubicin 30 mg/m2 i.v. on Days 1 and 29; mitomycin C 10 mg/m2 i.v. on Day 1; every 8 weeks). All eligible patients were included in the evaluation of response, toxicity and survival. RESULTS The PAM combination complete response (CR) rate was 8%, and the CR plus partial response (PR) rate was 21% (95% confidence interval [CI] from 10% to 32%). The median time to progression, duration of response, and duration of survival were 15, 26, and 29 weeks, respectively. The FAM combination CR rate was 2% and the CR plus PR rate was 26% (95% CI from 14% to 38%). The median time to progression, duration of response, and duration of survival were 17, 27, and 23 weeks, respectively. Hematologic and nonhematologic toxicity were mild with both regimens. CONCLUSIONS This study shows that this new combination, that does not include 5-fluorouracil, is active in patients with advanced gastric carcinoma. Since treatment with 5-fluorouracil alone is still considered the standard according to some authors, the PAM combination may be included among the sequential clinical options before or after treatment with 5-fluorouracil alone.

Abstract
PURPOSE To evaluate the endocrine effects as well as the pharmacokinetic parameters, efficacy and safety of letrozole, a new fourth-generation non-steroidal aromatase inhibitor. PATIENTS AND METHODS Fourteen postmenopausal women with progressive metastatic breast cancer, previously treated with endocrine therapy and/or chemotherapy for advanced disease, were treated with 0.5 mg daily doses of letrozole, orally. Endocrine and pharmacokinetic measurements were made before treatment and on days 14, 28, 56, and 84 of therapy. RESULTS Letrozole induced a >86% decrease in plasma estrone and a approximately 67% reduction in circulating estradiol from day 14 on. There was a statistically significant decrease in plasma cortisol, which appeared clinically irrelevant since all values remained within the normal range. No significant changes in aldosterone concentration were noted. One patient achieved a complete response (CR) and 4 patients a partial response (PR), with an objective response rate of 36% (95% CI 13% to 65%). Median duration of response was 24 months, ranging from 4 to 44 months. No toxic effects attributable to letrozole were noted in any patient. CONCLUSION Letrozole appears to be a very promising new antiaromatase drug. The characteristics of the patients more likely to respond, taking into account prior systemic treatment, should be defined by future studies. Further phase II and phase III studies comparing letrozole to other available second or even first-line endocrine-therapy agents, are warranted.

Abstract
BACKGROUND The observation that human meningiomas are rich in steroid hormone receptors has led to the hypothesis that their growth may be hormonally dependent. This study aims to correlate the biochemical expression of estrogen (ER) and progesterone receptors (PgR) with their nuclear immunoreactivity in a large series of meningiomas. METHODS The occurrence of ER and PgR in patients with primary untreated meningiomas was studied with a dextrancoated charcoal method (DCC) and the results were compared with those of an immunocytochemical assay (ICA). Progesterone and estrogen receptor determinations were performed on 103 and 99 meningiomas respectively using the DCC assay. Forty-six and 44 of these samples were immunocytochemically evaluated for the presence of PgR and ER respectively. RESULTS Of the 46 samples evaluated by both the methods, 89% were found PgR positive by DCC and 70% by ICA. The overall concordance between PgR-DCC and PgR-ICA was 80%. Whereas low concentrations of ER were found in 8/44 samples (18%) assayed by DCC, specific staining was never observed in any of the samples tested by ICA. CONCLUSIONS Our findings confirm that the majority of meningiomas are devoid of ER and that the biochemical evidence of PgR correlates well with the nuclear localization of progesterone receptors determined by immunocytochemistry.

Abstract
This paper aimed at reviewing information on the natural history of operable breast carcinoma after primary treatment. Breast carcinoma does not appear as a single disease entity, but as a wide variety of clinical manifestations. Primary loco-regional treatment should have a curative aim. However, the probability of early or late relapse increases according to a series of prognostic factors. The axillary node status remains the main prognostic indicator but especially in node-negative patients, an increasing number of additional morphologic and biological prognostic factors can classify patients according to a low, good or high risk categories. The natural history of the disease is influenced by loco-regional treatment as far as loco-regional control is concerned. The risk of relapse after loco-regional treatment alone differs during the first three years according to nodal status and it then tends to decrease and become more homogeneous. Adjuvant systemic therapies can decrease the probability of relapse, mainly in loco-regional but rarely in distant sites, thus limiting the absolute advantage. In any case, most women after primary treatment are not cured and are still carriers of occult disease. A timely diagnosis of first relapse after primary treatment is the direct aim of follow-up. An improvement in survival is only an indirect aim of the follow-up, and depends, if at all, on an anticipated diagnosis of recurrence, on the disease site in which this anticipated diagnosis is feasible and on application of different therapeutic strategies according to disease extension and to disease site. Follow-up could be tailored according to time after primary treatment (with more frequent examinations during the first three years than thereafter) and according to prognostic factors, mainly the axillary nodal status. Follow-up should not be considered as conceptually independent either from primary treatment or from treatment after recurrence. At time of first relapse, a new prognostic evaluation can be based on sites of disease recurrence, ER status at time of diagnosis and the time interval from primary treatment to relapse. Different therapeutic approaches could be planned according to survival expectation, including experimental treatments for patients having a dire prognosis.

Abstract
The Authors report the results with combination of cisplatin, methotrexate, vinblastine with adriamycin or epidoxorubicin (MVAC v MVEEC), in the neoadjuvant treatment of muscle-infiltrating bladder cancer (T2-4NO-1MO), before cystectomy. MVAC has been used in 29 patients and MVEEC in 25, who met eligibility criteria. Results from this prospective randomised trial show that MVAC and MVEEC can produce clinical and pathologic down-staging in 40-50% of cases: cCR+cPR are 15/28 (54%), pCR+pPR are 11/25 (44%). The survival duration of "pathologic" responders has been significantly longer than that of no responders (median no achieved at 200 weeks v 124 weeks for "pathologic" no responders). We conclude that neoadjuvant chemotherapy with MVAC or MVEEC select the more responsive patients, who have a longer survival.

Abstract
PURPOSE The combination of cisplatin, epirubicin, and leucovorin preceding fluorouracil (PELF) includes three novel agents compared with the standard combination of fluorouracil, doxorubicin, and mitomycin (FAM) in the treatment of advanced gastric carcinoma. We report the results of a prospective randomized comparison of the two combinations in previously untreated patients. PATIENTS AND METHODS One hundred thirty assessable patients were entered onto the trial; 52 received FAM and 85 PELF. A 1:2 unbalanced randomization in favor of the experimental treatment was chosen. Approximately 90% of patients had measurable tumor masses. RESULTS The overall response rates (complete responses [CRs] and partial responses [PRs]) were 15% and 43% for the FAM and the PELF regimens, respectively, with a statistically significant advantage for the experimental treatment (P = .001). Time to progression (median, 2.6 and 4.7 months), duration of response (median, 10.7 and 10.2 months), and survival durations (median, 5.6 and 8.1 months) were not significantly different between the FAM and PELF regimens, respectively. The PELF combination was more toxic compared with FAM, but generally tolerable. CONCLUSION This study showed that the PELF combination is about three times more effective than the FAM combination in inducing objective responses. Due to tolerability, it is not recommended for routine clinical use. However, it should be considered, among other second-generation chemotherapy combinations, in future randomized studies aimed to improve the therapeutic outcome in gastric carcinoma.

Abstract
Estrogen receptors (ERs) and progesterone receptors (PRs) were determined by an immunocytochemical assay (ICA) on fine needle aspirates (FNAs) from patients with primary, recurrent and metastatic mammary carcinoma, and the results were compared to those with the biochemical dextran-coated charcoal (DCC) method performed on the surgical sample in order to compare the two methods. The aspirates were suspended in a buffered saline solution, cytocentrifuged onto glass slides and immunocytochemically stained according to the protocol of commercial kits employing monoclonal antibodies specific for ER and PR. Immunocytochemical staining of malignant cells was evaluated on the basis of the percentage of stained cells; 10% staining was taken as the cutoff value. Fine needle aspiration biopsies (FNABs) from 107 breast carcinomas were analyzed immunocytochemically for ER and 31 of them for PR, also. The overall concordance between ICA and DCC was 88% for ER and 87% for PR. The sensitivity, specificity, and positive and negative predictive value of ICA on FNAs as compared to conventional DCC were 87%, 90, 97% and 63%, respectively, for ER and 85%, 100%, 100% and 56% for PR. These findings suggest that estrogen immunocytochemical assays and progesterone immunocytochemical assays on FNAs in breast cancer patients are reliable techniques for evaluating receptor status and can be useful in assessing ER and PR whenever surgical biopsy is not indicated and when information about ER and PR status is required at the time of the clinical diagnosis.

Abstract
The incidence of Kaposi's sarcoma (KS) in 1976-90 was assessed in Italy, taking advantage of a network of nine population-based cancer registries covering, at its maximum, approximately 5.6 million subjects. The first examined period (1976-84) substantially reflects the epidemiology of KS prior to the AIDS epidemic in the registration areas. Elevated incidence rates, standardised to the Italian population of 1981, of 1.05/100,000 men and 0.27/100,000 women emerged in 1976-84 (i.e. from two- to threefold higher than in the USA and Sweden, more than tenfold higher than in England and Wales). These high rates, especially remarkable in the Registry from the south of Italy (i.e. Ragusa, 3.01/100,000 men and 0.54/100,000 women) suggest that the prevalence of the still unknown causative agent for KS was high, at least in some parts of Italy, prior to the AIDS epidemic. In the most recent period (1985-90), an approximately twofold increase in KS incidence rates in Italian men below age 50 was observed (from 0.15 in 1976-84 to 0.47 in 1985-90). Conversely, declines in KS incidence were recorded in older men.

Abstract
Aminoglutethimide and testololactone may be considered the first generation aromatase inhibitors for the endocrine treatment of breast carcinoma. Initially, both of these agents were designed and used clinically based on different concepts of their mechanisms of action. Only later were they both demonstrated to inhibit aromatase. Curiously, testololactone was earlier and more widely used than aminoglutethimide in treating advanced breast carcinoma. The discovery of the peripheral aromatase inhibition as the proper mechanism of action was delayed for both the agents but was relatively more timely for aminoglutethimide. Paradoxically, the clinical use of testololactone has become already obsolete since its true mechanism of action was discovered. Aminoglutethimide is still the most widely used aromatase inhibitor in treating advanced breast carcinoma. Due to the initial misinterpretation of its mechanism of action, aminoglutethimide was used for a long time at a relative high daily dose, always combined with hydrocortisone. Subsequent phase II and then randomized phase III studies demonstrated an equivalent efficacy using half (500 mg) of the previous conventional daily dose (1000 mg), with hydrocortisone. Very recently, a randomized clinical trial demonstrated that administering this lower dose without hydrocortisone did not significantly decrease the clinical efficacy. By decreasing the dose of aminoglutethimide, the incidence of side effects has been reduced. So, the last paradoxical aspect of the aminoglutethimide story is that this agent seemed initially very toxic but finally, with the new schedules, shows a very low toxicity profile, especially after the first few weeks of treatment.

Abstract
BACKGROUND The M-VAC combination is very effective in bladder carcinoma, as are all four drugs, as single-agent, in advanced breast carcinoma. PATIENTS AND METHODS M-VAC was given in 27 patients, 4 with locally advanced breast carcinoma, 3 with local recurrence and 20 with distant metastases. The median age was 51 (range 25; 70). Eleven of the 20 patients with metastatic disease has been previously treated with a different chemotherapy. RESULTS 15 of 26 evaluable patients responded, with 9 (35%) complete remissions and 6 partial responses. The overall response rate (CR plus PR) was 57% (95% confidence interval 38% to 76%). In patients with metastatic disease the median duration of response was 7 months (range 4+; 36+), median time to progression 5 months (range 1; 36+) and median duration of survival 17 months (range 1; 40+). CONCLUSION The M-VAC combination is very effective in locally advanced, locally recurrent and metastatic breast carcinoma. Further trials are warranted to evaluate whether the activity of this combination is partially schedule-dependent.

Abstract
Fine-needle aspiration cytology has been already established as a reliable method for the diagnosis of breast cancer. Its application has been recently extended to immunocytochemical analysis of biological parameters. In the current study estrogen and progesterone receptors, Ki67 growth fraction, and p53 protein expression were immunocytochemically evaluated on the cellular material sampled by the same fine-needle aspirate used for the conventional cytologic diagnosis of malignancy. Fine-needle aspiration specimens from 100 patients with primary breast carcinoma were submitted to the immunocytochemical analysis. Twenty-eight percent were in premenopause; 23% had tumors with a diameter less than 2 cm, 59% from 2 to 5 cm, and 18% more than 5 cm; 60% had axillary nodal status negative, 34% positive, and 6% unknown. The concomitant immunocytochemical evaluation of all parameters was possible in 70% of the patients. A significant association was found between p53 overexpression and Ki67 values (p = 0.004), and between Ki67 values and progesterone receptor status (p = 0.003). No correlation was found between any parameter and clinical tumor size. Estrogen (p = 0.02) and progesterone (p = 0.04) receptor negativity and high Ki67 growth fraction (p = 0.005) were significantly associated with the clinical evidence of axillary node involvement. This study suggests that fine-needle aspiration cytology represents an effective practice for a simultaneous evaluation of multiple biologic indicators and could be useful as a preoperative procedure in patients who are candidates for neoadjuvant chemotherapy and/or endocrine therapy.
