Background: A population of breast cancer patients exists who, for various reasons, never received adjuvant post-operative tamoxifen (TAM). This study was aimed to evaluate the role of late TAM in these patients., Methods: From 1997 to 2003, patients aged 35 to 75 years, operated more than 2 years previously for monolateral breast cancer without adjuvant TAM, with no signs of metastases and no contraindication to TAM were randomized to TAM 20 mg/day orally for 2 years or follow-up alone. Events were categorized as locoregional relapse, distant metastases, metachronous breast cancer, tumours other than breast cancer and death from any causes, whichever occurred first. The sample size (197 patients per arm, plus 10% allowance) was based on the assumption of a 30% decrease in the number of events occurring at a rate of 5% annually in the 10 years following randomization. Four hundred and thirty-three patients were randomized in the study (TAM 217, follow-up 216). Patients characteristics (TAM/follow-up) included: median age 55/55 years, median time from surgery 25/25 months (range, 25-288/25-294), in situ carcinoma 18/24, oestrogen receptor (ER) positive in 75/68, negative in 70/57, unknown in 72/91 patients. Previous adjuvant treatment included chemotherapy in 131/120 and an LHRH analogue in 11/13 patients., Results: Thirty-six patients prematurely discontinued TAM after a median of 1 month, mostly because of subjective intolerance. Eighty-three events (TAM 39, follow-up 44) occurred: locoregional relapse in 10/8, distant metastases in 14/16, metachronous breast cancer in 4/10, other tumours in 11/10 patients. Less ER-positive secondary breast cancers occurred in the TAM treated patients than in follow-up patients (1 vs 10, p = 0.005). Event-free survival was similar in both groups of patients., Conclusions: This 5-year analysis revealed significantly less metachronous ER-positive breast cancers in the TAM treated patients. No other statistically significant differences have emerged thus far.

Aims and Background: Neoadjuvant chemotherapy is the standard treatment for locally advanced breast cancer. The combination of anthracyclines and taxanes is considered the first choice chemotherapy in advanced breast cancer. We report here the overall results of a phase II study of epirubicin and docetaxel as neoadjuvant chemotherapy in advanced breast cancer., Patients and Methods: Forty-five patients with locally advanced, nonmetastatic breast carcinoma were treated with epirubicin, 90 mg/m2, docetaxel, 75 mg/m2, intravenously, every 3 weeks for 4 cycles before and 4 cycles after surgery, followed by tamoxifen for 5 years if estrogen receptor positive and radiation therapy if indicated. Patient characteristics included a median age of 45 years; pre Ipostmenopausal, 311/14 patients; T3-T4 in 33, N0/N1 in 12/33; ductal/lobular in 42/3; ER+ in 23; and HER2 overexpression in 23., Results: Clinical response included complete remission in 7 patients and partial remission in 27 (response rate, 75%). All 45 patients underwent surgery (quadrantectomy in 7). Histological examination of the breast and lymph nodes revealed no signs of disease in 3 patients and ductal carcinoma in situ only in 2. Twenty-five patients completed the chemotherapy program. G3-G4 toxicity included neutropenia in 39 patients. No other G3-4 toxicity nor toxic deaths occurred. Median relapse-free and overall survival were 35 and 56 months, respectively., Conclusions: The neoadjuvant treatment was active and well tolerated, but the incidence of pathologic complete remissions was relatively low.

Background: Preclinical data have indicated a synergistic interaction between docetaxel and capecitabine by means of taxane-induced up-regulation of thymidine phosphorylase (TP). On the basis of such premises, we conducted a phase II trial to determine the activity and tolerability of weekly docetaxel plus capecitabine in patients with metastatic breast cancer (MBC). Furthermore, we explored the relationship between TP tumor expression and benefit from this regimen., Patients and Methods: Patients received docetaxel 36 mg/m(2) i.v. on days 1, 8, and 15 and capecitabine orally 625 mg/m(2) b.i.d. from days 8 to 21. Cycles were repeated every 4 weeks. In the correlative study, we evaluated the TP expression by immunohistochemistry and the TP messenger RNA expression by real-time RT-PCR in the primary tumor., Results: Forty-seven women were enrolled. In the intention-to-treat analysis, objective responses were achieved in 24 patients (51%). Fourteen additional patients (30%) had stable disease. The median time to progression (TTP) was 6 months (range 1-44 months). Median survival was 17 months (range 1-48 months). Overall, the treatment was well tolerated. The most common clinical adverse events (all grades) were alopecia (55%), nail changes (53%), fatigue/asthenia (51%), nausea/vomiting (51%), neutropenia (49%), and neuropathy (49%). A significantly higher TTP was observed in patients with TP-positive tumors (log-rank test, P = 0.009). Interestingly, a subgroup analysis confirmed this TTP benefit in patients with TP-positive tumors obtaining a tumor response (log-rank test, P = 0.03), whereas the statistical significance was lost in nonresponders (log-rank test, P = 0.3)., Conclusions: This study indicates that a regimen with low doses of capecitabine plus weekly docetaxel is active against MBC. The correlative analysis provides preliminary evidence that TP expression may be a predictive marker for therapeutic benefit.

Aims and Background: Trastuzumab-based therapy has improved survival of women with human epidermal growth factor receptor 2 (HER2)-overexpressing metastatic breast cancer., Study Design: From September 2002 to July 2006, 45 women with metastatic breast cancer HER2 3+, or 2+ and positive for HER2 gene amplification, were enrolled in the study and received a combination therapy with vinorelbine, 25 mg/m2 weeks 1 and 2, plus trastuzumab, 4 mg/kg loading dose and then 2 mg/kg weekly, in a three weeks cycle. Eligibility criteria included measurable disease and a baseline ejection fraction > or = 50%. Forty-two percent of the patients were not pretreated, whereas 58% had received a previous chemotherapy regimen for metastatic disease, including anthracyclines and/or taxanes (47%), and trastuzumab plus taxol (11%)., Results: We observed 14 (31%) complete responses and 21 (47%) partial responses, with an overall response rate of 78%. Stable disease > 6 months was assessed for 5 (11%) patients with a clinical benefit of 89%. Five (11%) patients progressed. With a median follow-up of 11 months, median time to progression was 9 months and median duration of response was 7.6 months for complete remissions and 4 months for partial remissions. Median survival was 29 months., Conclusions: In spite of a smaller dose intensity of vinorelbine than previously reported, the regimen evaluated was notably effective in terms of response rate, time to progression and survival, with very mild toxicity.

Background: To determine if protracted low-dose oral idarubicin (IDA), feasible in a previous dose-finding study, would result in similar activity and a better toxicity profile in patients with metastatic breast cancer., Patients and Methods: Elderly women (> or=65 years) with metastatic breast carcinoma were treated with 7.5 mg/day for 21 consecutive days, every 4 weeks. After the first fourteen patients, due to excessive toxicity, the protocol was amended to 5 mg/day. IDA and Idarubicinol (IDOL) plasma concentrations (C(trough)) were investigated in all patients., Results: Between April 1999 and June 2004, 47 elderly patients were accrued in this two-part study (14 and 33 patients respectively). The median age was 74 and 75 years respectively. Visceral involvement was present in most patients. A partial response was noted in 7/31 patients (22%; 95% CI, 9.6-41.1%). Eleven patients had stable disease (33%). At the dose of 5 mg/day the treatment was well tolerated. Neutropenia grade 4 was present in only 6% of patients; alopecia > grade 1 and cardiotoxicity did not occur. The median time to progression was 3 months and the median overall survival was 17 months. IDA C(trough) and IDOL C(trough) levels were significantly associated with haematologic toxicity., Conclusion: This study shows that idarubicin at the dose of 5 mg/day for 21 consecutive days is feasible and effective in elderly breast cancer patients but do not demonstrate an improvement in efficacy. A determination of the IDA and IDOL plasma levels (C(trough)) is predictive for toxicity.

Background: The clinical and pathological characteristics and the clinical course of patients with breast cancer and BRCA 1-2 mutation are poorly known., Methods: From 1997, patients with breast cancer and a family history of breast or ovarian cancer were offered BRCA testing. The clinical and pathological features of patients with known BRCA status were retrospectively assessed and comparisons were made between cancers arising in BRCA positive and BRCA wild type (WT) patients respectively. Type of treatment, pattern of relapse, event (local relapse, contralateral breast cancer, metastases) free and overall survival were also compared in the two groups. Out of the 210 patients tested, 125 had been treated and followed-up at our Institution and were evaluated in this study., Results: BRCA positive patients tended to be more often premenopausal (79% vs 65%) and to have positive lymphnodes (63% vs 49%), poorly differentiated tumours (76% vs 40%--p = 0.002 at univariate analysis, not significant at multivariate analysis) and negative estrogen receptors (43% vs 29%). Treatment was not different in the two groups. In the 86 BRCA-WT patients, the first event was a local relapse in 3 (3%), metachronous contralateral breast cancer in 7 (8%) and distant metastases in 16 (19%). In the 39 BRCA positive patients, the corresponding figures were 3 (8%), 8 (21%) and 3 (8%). There was no difference in event free survival, with a median of 180 months in both groups of patients. At 20 years, projected survival was 85% for BRCA positive patients and 55% for BRCA-WT, but this difference was not statistically significant., Conclusion: Although BRCA positive patients have more frequently negative prognostic factors, their prognosis appears to be equal to or better than in patients with BRCA-WT.

Aims and Background: A dose-dense therapy with weekly paclitaxel given as a 1-hr infusion yielded a 53% overall response rate in breast cancer patients resistant to anthracyclines, with a remarkable lack of neutropenia (Seidman, 1998). We performed a monoinstitutional phase II trial in order to confirm these interesting results., Patients and Methods: Eligibility criteria included advanced breast cancer and no taxane pretreatment. Paclitaxel was administered weekly at the dose of 90 mg/m2 (60 mg/m2 in patients at high risk of toxicity) by 1-hr i.v. infusion. Fifty-eight patients entered the trial. Median age was 54 years (range, 38-72). Performance status was good (median 1; range, 0-2). Fifty-two patients were pretreated with anthracyclines., Results: A total of 1,004 weekly paclitaxel infusions were administered (median, 19 per patient; range, 4-43). The median delivered dose intensity was 67.4 mg/m2/week (range, 43-86). Twenty-eight of the 58 assessable patients obtained an objective response (48%), 15 had stable disease (26%) and 15 progressed (26%). The overall response rate was 48% (95% confidence interval, 35-61%) with 5 complete responses (8%). In anthracycline-pretreated patients, 23/52 (44%) responses were observed. Median duration of response was 5 months (range, 3-27). Toxicity was acceptable apart from a case of pulmonary embolism in a 70-year-old patient, 1 case of congestive heart failure in an anthracycline-pretreated patient aged 64, and 9 cases of G3 neutropenia. Peripheral neuropathy was observed in 38 patients (64%), usually of a mild grade; alopecia in 45 patients (78%) and onychopathy in 16 (28%), usually of a mild grade apart from 2 cases requiring treatment interruption. Tachycardia and atrial fibrillation occurred in a 55-year-old woman., Conclusions: Our data seem to confirm the activity and safety of this approach even in a heavily pretreated population of patients. Its combination with other active drugs needs to be further investigated in clinical trials.

Background: We investigated the physical and psychological adaptation to a protracted continuous infusion system in a series of patients receiving protracted continuous infusion of 5-fluorouracil for advanced breast cancer., Patients and Methods: The protracted continuous infusion of 5-fluorouracil was administered by means of a portable elastomeric pump (Baxter Seven-Day Infusor, 0.5 mL/hr) via an indwelling Groshong catheter. Patients were asked to complete a questionnaire exploring the impact of the continuous infusion system upon various aspects of daily life, the overall level of disturbance, the general judgement on its quality, and their willingness to resume the same kind of treatment in the future. All items were graded on a 4-point scale from 0 = not at all, to 4 = very much., Results: Seventy-one patients were evaluated. All patients received 5-fluorouracil at the dose of 250 mg/m2/day as a protracted continuous infusion alone (n = 14) or in combination with vinorelbine (n = 45) or Taxol (n = 12). The median duration of the protracted continuous infusion before evaluation was 9 months (3-31). The mean level of disturbance to daily activities was 0.86 points. The activities most frequently disturbed by treatment included daily personal care (mean, 1.76 points) and sexual activity (mean, 1.20 points). Twenty-one patients required medical intervention because of problems related to the protracted continuous infusion system. The overall level of disturbance was rated at a mean level of 0.72 points, whereas the overall merits of the protracted continuous infusion system and the willingness of the patient to resume protracted continuous infusion in the future were rated at a mean level of 2.90 and 2.55 points, respectively., Conclusions: The system for the protracted continuous infusion of 5-fluorouracil was well tolerated by the patients, who were able in most cases to perform their daily activities with little or no disturbance, needing only occasional help, and were willing to resume the same treatment modality if necessary.

Adjuvant treatment of elderly women affected by breast cancer who have a high risk of recurrence is one of the most questionable issues in clinical oncology. The use of tamoxifen in women with hormone receptor-positive tumors is a relatively simple therapeutic option considering the favourable toxicity profile, whereas the administration of adjuvant chemotherapy is more complicated and a variety of aspects need to be considered. The estimated life expectancy, the presence and degree of comorbid conditions, the geriatric assessment and estimated benefit from treatment should be taken into account. Due to the lack of data from clinical trials in women over the age of 70, the approach is still experimental. Clinical trials evaluating the role of adjuvant chemotherapy in high risk patients are currently being developed and hopefully in the near future, more convincing data on the best drugs, regimens and benefits for the treatment of elderly breast cancer patients will become available.

The diagnosis of breast cancer during pregnancy is a rare event, but the young age of the patient together with the emotional impact for both the family and the doctors make therapeutic choices usually very difficult. Until recently, the occurrence of pregnancy associated breast cancer was thought to hold a grave prognosis and therapeutic abortion was very often advised in common practice. The hormonal environment with the increase in estrogens and progesterone was the main factor for the fear of tumor stimulation. The course of breast cancer, however, does not appear to be adversely affected by continuation of pregnancy. In the last years it was realized that potentially curative therapies can be administered even when pregnancy is continued. Of course in the medical literature there is no randomized clinical trial helping in taking decision in this setting; however, a significant experience already exists in some institutions and can guide management in these difficult cases. The aim of our review is to give an answer to questions usually coming from various specialists who collaborate with the oncologists in treating these patients and furthermore to try and find some basic guidelines which can be used in the information of the patients regarding previous experience in this field. The problem of a pregnancy after treatment for breast cancer is also analyzed, as this aspect is an emerging issue in clinical oncology. The decision should be evaluated for each single patient, taking into account the prognosis of the patient and her desire of pregnancy.

Aims and Background: Ifosfamide is an active drug in advanced breast cancer. Short-term continuous infusion schedules have been evaluated with encouraging results. The aim of the study was to evaluate in patients with advanced breast cancer a 14-day infusion schedule previously tested at our center in soft tissue sarcomas., Methods: From July 1998 to February 2000, 26 consecutive patients with heavily pretreated breast cancer, progressing during protracted continuous infusion of fluorouracil, were treated with ifosfamide at the dose of 800 mg/m2/day for 14 consecutive days by means of an elastomeric pump via an in-dwelling Groshong catheter. The median age of the patients was 52 years (range, 32-67) and median PS was 1 (range, 1-3). All patients were pretreated with anthracyclines or taxanes; the median number of chemotherapy lines in the metastatic phase was 2 (range, 1-4). Predominant metastatic sites wen soft tissues in 5 patients, lung in 6, liver in 7 and serosal cavities in 3., Results: Twenty-four patients were assessable for response Two complete responses and 2 partial remissions were noted for an overall 16.6% response rate. The duration of response was 3+, 5, 8 and 10 months, respectively. Stabilization or mi nor response was observed in 2 more patients. The main tox ic effect was myelosuppression (grade 1-2 in 15 patients grade 3-4 in 4). Other toxicities included nausea in 14 patients (grade 3 in 2) and grade 1-2 vomiting in 2 patients. Hair lost or alopecia was universal., Conclusions: The regimen yielded some clinically useful re sponses with acceptable toxicity. Its evaluation in less ad vanced cases appears to be warranted.

Concentrations of tamoxifen and its metabolites were analysed in the endometrium of 23 post-menopausal asymptomatic breast cancer patients who were on chronic tamoxifen therapy. Small endometrial samples were collected during diagnostic hysteroscopy. Analysis of both serum and tissue for these compounds was performed by mass spectrometry. Tamoxifen and its metabolites were far more concentrated in the endometrium than in serum; tamoxifen was also significantly more concentrated in endometrium with hyperplastic changes than in atrophic endometrium. Endometrial polyps of an additional 9 women showed a trend to a lesser concentration of compounds. Increased concentration of tamoxifen compounds could possibly be explained by the avidity of these compounds for oestrogen receptors (ER).

Background: The protracted continuous infusion (PCI) of 5-fluorouracil (5-FU) has proven in several studies an active and well tolerated treatment for advanced, pretreated breast cancer. Navelbine has also activity in this setting., Patients and Methods: Heavily pretreated patients with metastatic breast carcinoma were eligible for the study. Treatment consisted of 5-FU 250 mg/m2 given as a PCI by an elastomeric pump and navelbine 20 mg/m2 on days 1 and 8, every four weeks. Eighty-three patients (median age 54 years; range 32-82 years) entered the study. The median number of metastatic tumour sites was 2, with visceral involvement in 56 patients. Apart from five patients with contraindications, all patients had been pretreated with anthracyclines. Thirty-one patients had received taxanes and seventy-four bolus 5-FU., Results: A median of 5 cycles (range 1-14) per patient was administered. The median duration of 5-FU infusion was 17 weeks (range, 4-90). In the 80 evaluable patients (3 not yet evaluable) 12 complete remissions and 24 partial remissions occurred (response rate, 45%). Median duration of response was 9 months. Toxicity was mild. Median survival was 20 months., Conclusions: PCI-5-FU combined with navelbine offers a reasonable chance of tumour regression with modest side effects in patients with heavily pretreated breast cancer.

Aims and Background: The evaluation of unconventional schedules of well-known drugs represents a promising avenue in the search for new regimens with a better therapeutic index in metastatic breast cancer. In particular, protracted continuous infusion (PCI) of 5-fluorouracil (5-FU) has yielded interesting results in gastrointestinal malignancies and in breast cancer., Methods: From March 1996 30 consecutive patients with heavily pretreated breast cancer were treated with PCI 5-FU at a daily dose of 250 mg/m2 by means of disposable elastomeric pumps until progression or toxicity. The median age was 54 years (range, 28-71) and median performance status was 1 (range, 0-3). All patients but four were pretreated with anthracycline-containing regimens or taxanes; the median number of chemotherapy lines was 3 (range, 2-4). Metastatic sites were predominantly visceral in 60% of the patient population., Results: All 30 patients were evaluable for response and toxicity. The median duration of PCI was 20 weeks (range, 2-36 weeks). Two complete responses (7%) and eight partial remissions (26%) were observed, giving an overall response rate of 33%. The median duration of response was six months (range, 4-9 months). Stabilization was observed in seven patients (23%) with a median duration of seven months (range, 3-9 months). The main toxic effects were grade I-II mucositis and hematologic toxicity, while grade 3 hand-foot syndrome was observed in eight patients (27%)., Conclusions: This study confirms the efficacy and safety of 5-FU at this dosage and schedule in heavily pretreated women with advanced breast cancer. In order to improve on these results further studies are needed in a less advanced stage of the disease and together with other active drugs.

The heritable defects of BRCA1 and BRCA2 genes have been shown to predispose to breast and ovarian cancers. In a previous report, we analyzed 46 Italian families with breast and/or ovarian cancer for BRCA1 mutations. In the present study, those families and 11 others were screened for BRCA2 mutations; the newly enrolled families were also analyzed for the BRCA1 gene. The coding region and splice boundaries of BRCA2 and BRCA1 genes were assessed by the protein-truncation test and single-strand conformational polymorphism. A total of 20 different mutations were found in 21 families (37%). A total of 9 families (16%) showed mutations in the BRCA1 gene, including the one new mutation identified in this study (5382insC), and 12 families (21%) presented mutations in the BRCA2 gene. BRCA2-mutated families presented breast and ovarian cancers or breast cancers only, whereas most BRCA1-mutated families presented ovarian cancer alone or in association with breast cancer. All the BRCA2 mutations led to a truncated protein: 6 were frameshift mutations, 4 were non-sense mutations and 2 involved the intronic invariant region leading to splice variants. Therefore, in the Italian population, the cumulative proportion of BRCA1 and BRCA2 mutations was within the range observed in other studies (37%), with higher involvement of BRCA2 than of BRCA1. Many families in which no mutations were found presented a very high incidence of breast and/or ovarian cancer. Among the 36 BRCA1 and BRCA2 wild-type families, 24 presented at least 4 cancer cases, indicating the existence of other important predisposing genes., (Copyright 1999 Wiley-Liss, Inc.)

Most familial breast or ovarian cancers are thought to be due to highly penetrant mutations in the predisposing genes BRCA1 and BRCA2. The cloning of these genes has opened a new era for the genetic counseling of women with a family history of breast or ovarian cancer. To estimate the incidence of detectable BRCA1 mutations and to define the eligibility criteria for genetic testing in the Italian population, a total of 53 patients belonging to 46 families clustering multiple cases of breast and/or ovarian cancer were investigated. Seven families presented with ovarian cancer only, 16 had both ovarian and breast cancers, and 23 were characterized by breast cancer only. Using a combination of protein truncation test (PTT) and single strand conformational polymorphism (SSCP) analysis followed, when necessary, by direct sequencing, we found 8 distinct mutations, 2 of these not reported before. Five frameshift and 2 nonsense mutations led to a truncated protein. One mutation was a missense substitution involving a cysteine in the zinc finger domain. One variant creating an ETS binding site in intron I was found but its role was not defined. The percentage of families carrying mutations was 17%. Among the families characterized by ovarian cancer only and by breast and ovarian cancer, the percentage of BRCA1 mutations was 57% and 12.5%, respectively. In contrast, the percentage of altered BRCA1 in families with only breast cancers was 9%. In the 46 Italian families studied, BRCA1 mutations were detected in fewer kindreds than those previously hypothesized based on linkage analysis, especially when these were characterized by breast cancers only. Our results indicate that families with a low number of cancer patients should be referred for BRCA1 genetic testing mainly when ovarian cancer is present.

Aim: The aim of this study was to investigate whether tamoxifen toxicity and treatment discontinuations differed in the adjuvant versus chemopreventive setting., Methods: At our Institutions 119 postmenopausal breast cancer patients were randomized from August 1987 to March 1995 to tamoxifen only within adjuvant studies (International Breast Cancer Study Group studies VII and IX) and 202 healthy hysterectomized women aged 35-70 years were randomized from November 1993 to May 1996 in a multicenter, double-blind, placebo-controlled chemoprevention study (Italian Tamoxifen Prevention Study). The tamoxifen dose was 20 mg/day for 5 years in all studies. Median age was 66 years (54-85) in the adjuvant studies and 53 years (37-69) in the chemoprevention study. Median treatment duration was 238 and 120 weeks, respectively., Results: Patients treated within adjuvant studies experienced more hot flashes, vaginal discharge and/or bleeding, bone marrow depression and weight gain than those treated in the chemoprevention study, consistent with the fact that a proportion of women in the latter study were receiving placebo. Temporary discontinuation occurred in 2.5% of patients in the adjuvant studies and in 5.4% of women in the chemoprevention study (difference not statistically significant). Permanent discontinuation was more frequent in the chemoprevention study than in the adjuvant ones (26.7% vs 15.1%--P< 0.05)., Conclusions: In summary, our data show that, although the toxicity of tamoxifen is superimposable in the two settings, a larger proportion of women treated as chemoprevention discontinue treatment spontaneously. Due to the double-blind nature of the chemoprevention study, the impact of the toxicity of tamoxifen upon compliance in the chemopreventive setting cannot be ascertained.

Forty-six evaluable postmenopausal patients with locally advanced, inoperable T3-T4 breast carcinoma were treated with tamoxifen 10-20 mg twice daily for a period at least 6 weeks. Eight patients (17%) had an objective response at the primary tumor site after 6 weeks of treatment. Improvement of response with a further single tamoxifen therapy was observed in 7 patients, resulting in an overall objective response in 14 of 46 (30%). Median duration of response was 8 months (range 2-24). No response was obtained in the 5 patients with inflammatory signs. Toxicity of treatment was minimal. Medial survival was 10 months (responders 17.5, non-responders 9). Tamoxifen seems to be safe and effective treatment for locally advanced breast cancer without inflammatory signs in postmenopausal women.

Carcinoembryonic antigen (CEA) assays (2536) were performed in 380 disease-free breast cancer patients after radical mastectomy. In the 334 evaluable patients with 3 or more determinations, the overall relapse rate after a median follow-up of 29 months was 11%. Of 203 patients with normal CEA values, 19 (9.3%) relapsed. In the 50 patients with the highest CEA value greater than 20 ng/ml, the relapse rate was 26%; in the 12 patients with gradually increasing CEA elevations it was 50%. However, CEA was unable to predict recurrence in N- patients. Premastectomy N+ was significantly associated with greater than 20 ng/ml or gradually increasing CEA values, suggesting the lack of an independent prognostic value of CEA in our patient population.
