Impact of hormonal status on outcome of ductal carcinoma in situ treated with breast-conserving surgery plus radiotherapy: Long-term experience from two large-institutional series.

BACKGROUND: Ductal carcinoma in situ (DCIS) is a heterogeneous disease, for which the best adjuvant treatment is still uncertain. Many attempts of risk-groups stratification have been made over time, developing prognostic scores to predict risk of local recurrence (LR) on the basis of features such as age, final surgical margins (FSM) status, grade, and tumor size. The aim of our analysis was to evaluate the patterns of recurrence from a two large-institutional retrospective series. PATIENTS AND METHODS: We collected data on 457 patients treated with BCS and adjuvant RT between 1990 and 2012. Final analysis was performed on 278 patients, due to missing data about hormonal status (HS). Patients were treated at the Radiation Oncology Unit of the University of Florence (n = 195), and S. Maria Annunziata Hospital (n = 83) (Florence, Italy). RESULTS: At a median follow up time of 10.8 years (range 3-25), we observed 20 LR (7.2%). The 5-year and 10-year LR rates were 4.9% and 10.2%, respectively. At Cox regression univariate analysis, estrogen receptor (ER) positive status (p = 0.001), HS positive (p = 0.003), and FSM <1 mm (p = 0.0001) significantly impacted on LR. At Cox regression multivariate analysis positive ER status maintained a protective role (p = 0.003), and FSM status <1 mm its negative impact (p = 0.0001) on LR rate. CONCLUSIONS: Our experience confirmed the wide heterogeneity of DCIS. Inadequate FSM and negative ER status negatively influenced LR rates. Tumor biology should be integrated in adjuvant treatment decision-making process.

Safety of eribulin mesylate and concomitant radiotherapy for metastatic breast cancer: a single-center experience.

AIM: This study evaluates, for the first time, the safety of eribulin in metastatic breast cancer patients concomitantly treated with palliative radiotherapy (RT). Patients & materials: A total of 17 patients were pretreated for metastatic breast cancer. Patients received eribulin mesylate and bone RT. RESULTS: The most frequent grade 3 hematologic adverse events were neutropenia (56%) and anemia (20%). Mean pain score decreased from 2 (baseline) to 0.7 (end of observation). Analgesic score remained stable (1.8 vs 1.6). Bone pain scores dropped within a few weeks and remained below baseline values throughout the analysis. The overall response rate was 29%, and the clinical benefit rate was 59%. CONCLUSION: Eribulin is characterized by a manageable safety profile also when combined with palliative RT.

Impact of age on cytotoxic-induced ovarian failure in breast cancer treated with adjuvant chemotherapy and triptorelin.

AIM: This study analyzes our single-center, retrospective experience on 63 premenopausal breast cancer patients treated with monthly triptorelin and concomitant chemotherapy. PATIENTS & METHODS: Concomitant chemotherapy and triptorelin were adopted as part of premature ovarian failure prevention strategy. RESULTS: Age at diagnosis was the main factor influencing fertility preservation (p = 0.002). Compared with patients aged 41-45 years, the probability of menses resumption was almost threefold than for women aged 35-40 years, and significantly higher for women aged <35 years (hazard ratio: 9.0; p = 0.0001). The cumulative proportion among patients who resumed menses was 33.3% at 6 months, 75% at 12 months and 87.5% at 24 months. Seven patients attempted pregnancy, and five (71%) obtained healthy deliveries. CONCLUSION: We observed an acceptable rate of fertility preservation. Age at diagnosis influences fertility preservation.

Accelerated partial breast irradiation using intensity-modulated radiotherapy technique compared to whole breast irradiation for patients aged 70 years or older: subgroup analysis from a randomized phase 3 trial.

The purpose of this study was to report the efficacy and the safety profile on the subset of selected early breast cancer (BC) patients aged 70 years or older from a single-center phase 3 trial comparing whole breast irradiation (WBI) to accelerated partial breast irradiation (APBI) using intensity-modulated radiation therapy technique. Between 2005 and 2013, 520 patients aged more than 40 years old were enrolled and randomly assigned to receive either WBI or APBI in a 1:1 ratio. Eligible patients were women with early BC (maximum diameter 2.5 cm) suitable for breast conserving surgery. This study is registered with ClinicalTrials.gov, NCT02104895. A total of 117 patients aged 70 years or more were analyzed (58 in the WBI arm, 59 in the APBI arm). At a median follow-up of 5-years (range 3.4-7.0), the ipsilateral breast tumor recurrence (IBTR) rate was 1.9 % in both groups. No significant difference between the two groups was identified (log-rank test p = 0.96). The 5-year disease-free survival (DFS) rates in the WBI group and APBI group were 6.1 and 1.9 %, respectively (p = 0.33). The APBI group presented significantly better results in terms of acute skin toxicity, considering both any grade (p = 0.0001) and grade 2 or higher (p = 0.0001). Our subgroup analyses showed a very low rate and no significant difference in terms of IBTR, using both WBI and APBI. A significant impact on patients compliance in terms of acute and early late toxicity was shown, which could translate in a consistent improvement of overall quality of life.

Predictive factors for additional non-sentinel lymph node involvement in breast cancer patients with one positive sentinel node.

AIM: The aim of this study was to identify a subgroup of breast cancer patients in whom it is possible to avoid axillary lymph node dissection (ALND) when the sentinel lymph node (SLN) is positive. METHODS: A series of 292 patients treated with breast-conserving surgery or mastectomy underwent ALND after positive SLN detection. To correlate SLN metastasis with the chances of finding additional metastasis in non-SLNs we evaluated the main clinicopathological characteristics. No patients received adjuvant radiotherapy to the axillary region. RESULTS: Fifty-six patients (35.4%) with positive SLNs for macrometastases (n = 158) had additional metastases upon completion ALND compared with 7 patients (5.2%) with micrometastases in the SLN (n = 132). Cases with a higher number of positive axillary lymph nodes tended to have higher pT stage (p = 0.004). In multivariate analysis, pT was confirmed as an independent predictor of non-SLN metastases (OR = 2.40; 95% CI = 1.16-4.99). No patients with micrometastases in SLN and cancer lt;10 mm had additional positive non-SLNs. CONCLUSIONS: Our results, in agreement with the major published studies, suggest that ALND can be avoided in selected patients without the need for additional treatment to the axillary region.

Aprepitant as prophylaxis of chemotherapy-induced nausea and vomiting in anthracyclines and cyclophosphamide-based regimen for adjuvant breast cancer.

The aim of our study was to evaluate the efficacy and safety of a three-drug antiemetic prophylaxis in a single-center series treated with anthracyclines and cyclophosphamide-based regimen for BC. We collected data from 92 consecutive patients treated with routine antiemetic prophylaxis consisted of aprepitant (oral 125 mg, on day 1; oral 80 mg, on days 2 and 3), a 5-HT3 receptor antagonist (palonosetron iv 0.25 mg, on day 1), and dexamethasone (iv 12 mg, on day 1). Acute and delayed phases were defined as the first 24 h and days 2-5 after treatment, respectively. Therapy outcomes were defined as complete response (CR), in case of no vomiting, no rescue treatment; complete protection (CP), in case of no vomiting, no rescue treatment, no significant nausea; and total control (TC), in case of no vomiting, no rescue treatment, no nausea. Overall, 89.1 and 81.5% of patients showed CR in acute and delayed phase, respectively; 67.4 and 62% showed CP in acute and delayed phase, respectively; and 52.2 and 48.9% of patients showed TC in acute and delayed phase, respectively. 4.3% complained an episode of emesis during the first 24 h from treatment, while in delayed phase, only 2.2% of patients had vomiting. Our analysis confirmed that a three-drug prophylaxis is safe, effective, and consequently highly recommended in patients who undergo anthracyclines and cyclophosphamide-based regimens, though still not classified as highly emetogenic chemotherapy by all the international guidelines.

Accelerated partial breast irradiation using intensity-modulated radiotherapy versus whole breast irradiation: 5-year survival analysis of a phase 3 randomised controlled trial.

BACKGROUND: Accelerated partial breast irradiation (APBI) has been introduced as an alternative treatment method for selected patients with early stage breast cancer (BC). Intensity-modulated radiotherapy (IMRT) has the theoretical advantage of a further increase in dose conformity compared with three-dimensional techniques, with more normal tissue sparing. The aim of this randomised trial is to compare the local recurrence and survival of APBI using the IMRT technique after breast-conserving surgery to conventional whole-breast irradiation (WBI) in early stage BC. METHODS: This study was performed at the University of Florence (Florence, Italy). Women aged more than 40years affected by early BC, with a maximum pathological tumour size of 25mm, were randomly assigned in a 1:1 ratio to receive either WBI or APBI using IMRT. Patients in the APBI arm received a total dose of 30 Gy to the tumour bed in five daily fractions. The WBI arm received 50Gy in 25 fractions, followed by a boost on the tumour bed of 10Gy in five fractions. The primary end-point was occurrence of ipsilateral breast tumour recurrences (IBTRs); the main analysis was by intention-to-treat. This trial is registered with ClinicalTrials.gov, number NCT02104895. FINDINGS: A total of 520 patients were randomised (260 to external WBI and 260 to APBI with IMRT) between March 2005 and June 2013. At a median follow-up of 5.0 years (Interquartile Range (IQR) 3.4-7.0), the IBTR rate was 1.5% (three cases) in the APBI group (95% confidence interval (CI) 0.1-3.0) and in the WBI group (three cases; 95% CI 0.0-2.8). No significant difference emerged between the two groups (log rank test p=0.86). We identified seven deaths in the WBI group and only one in the APBI group (p=0.057). The 5-year overall survival was 96.6% for the WBI group and 99.4% for the APBI group. The APBI group presented significantly better results considering acute (p=0.0001), late (p=0.004), and cosmetic outcome (p=0.045). INTERPRETATION: To our knowledge, this is the first randomised study using the IMRT technique for APBI delivery. No significant difference in terms of IBTR and overall survival was observed between the two arms. APBI displayed a significantly better toxicity profile.

Radiotherapy timing in the treatment of limited-stage small cell lung cancer: the impact of thoracic and brain irradiation on survival.

AIMS AND BACKGROUND: Small cell lung cancer is an aggressive histologic subtype of lung cancer in which the role of chemotherapy and radiotherapy has been well established in limited-stage disease. We retrospectively reviewed a series of limited-stage small cell lung cancers treated with chemotherapy and thoracic and brain radiotherapy. METHODS AND STUDY DESIGN: A total of 124 patients affected by limited-stage small cell lung cancer has been treated over 10 years in our Institute. Fifty-three patients (42.8%) had concomitant radio-chemotherapy treatment and 71 patients (57.2%) a sequential treatment. Eighty-eight patients (70.9%) underwent an association of a platinum-derived drug (cisplatinum or carboplatinum) and etoposide. Prophylactic cranial irradiation was planned in all patients with histologically proven complete response to primary radio-chemotherapy. RESULTS: With a mean follow-up of 2.2 years, complete response was obtained in 50.8% of cases. We found a significant difference between different radio-chemotherapy association approaches (P = 0.007): percentages of overall survival were respectively 10.0%, 12.9% and 5.6% in early, late concomitant and sequential radio-chemotherapy timing. Cranial prophylaxis did not seem to influence overall survival (P = 0.21) or disease-free survival for local relapse (P = 0.34). CONCLUSIONS: Concomitant radio-chemotherapy is the best approach according to our experience. Our results show a benefit of prophylactic cranial irradiation in distant metastasis-free survival.

Multiple cutaneous angiosarcomas after breast conserving surgery and bilateral adjuvant radiotherapy: an unusual case and review of the literature.

Breast angiosarcomas (BAs) are rare but serious events that may arise after radiation exposure. Disease outcome is poor, with high risk of local and distant failure. Recurrences are frequent also after resection with negative margins. The spectrum of vascular proliferations associated with radiotherapy in the setting of breast cancer has expanded, including radiation-associated atypical vascular lesions (AVLs) of the breast skin as a rare, but well-recognized, entity. Although pursuing a benign behavior, AVLs have been regarded as possible precursors of postradiation BAs. We report an unusual case of a 71-year-old woman affected by well-differentiated bilateral cutaneous BA, diagnosed 1.9 years after adjuvant RT for synchronous bilateral breast cancer. Whole-life clinical followup is of crucial importance in breast cancer patients.

Cutaneous and cardiac toxicity of concurrent trastuzumab and adjuvant breast radiotherapy: a single institution series.

Pilot studies have shown that patients with human epidermal growth factor receptor 2-positive disease have greater risk of relapse and death. The sooner trastuzumab is administered, the greater seems to be the benefit. A delay in the initiation of adjuvant radiotherapy (RT) may result in an increased rate of local recurrence. Since limited published data exist, the aim of our analyses was to evaluate the skin and heart toxicity of concomitant treatment. Between 2003 and 2012, 95 women were treated at our Institute by concomitant therapy for clinical stage I-III invasive breast cancer. Cardiac toxicity was evaluated according to the left ventricular ejection fraction (LVEF) decrease, with a prospective monitoring program. All acute and late toxicities were assessed according to the CTCAE-v3 criteria. At a median follow-up of 4.3 years (range 1.3-10.4), 5 patients developed locoregional relapse and 7 patients developed distant metastases; disease-free survival was 90% and overall survival 97.9%. Overall, skin toxicity ≥ Grade 2 was recorded in 13 patients (13.7%). No dysphagia and esophagitis ≥ Grade 2 were recorded. Cosmetic outcome was excellent in 41 patients (43.2%), good in 39 patients (41.1%), and fair in 10 patients (10.5%). All patients concluded the programmed RT. Among the 58 patients (61.1%) that recorded a LVEF dysfunction, the median decrease from baseline to the end of trastuzumab was 10%, while the median decrease from baseline to the last follow-up was 7% (p = 0.01). In our experience, concomitant trastuzumab and radiation treatment was overall well tolerated.

Impact of a breathing-control system on target margins and normal-tissue sparing in the treatment of lung cancer: experience at the radiotherapy unit of Florence University.

PURPOSE: In lung cancer, a high radiation dose to the target area correlates with better local control but is frequently counterbalanced by a higher risk of lung toxicity. Several methods exist to coordinate respiratory motion in lung radiotherapy. We aimed to investigate the impact of a breathing-control system on irradiated volumes and dosimetric parameters in three-dimensional conformal radiotherapy (3D-CRT) and stereotactic radiotherapy (SRT) treatments. MATERIALS AND METHODS: Twelve patients were scheduled for radical radiotherapy: five for SRT and seven for 3D-CRT. For each patient, in addition to the free-breathing computed tomography (CT) scan, four additional sets of CT slices were acquired using the Active Breathing Coordinator device (ABC, Elekta Oncology Systems Ltd., UK). RESULTS: The volumes acquired with the ABC device were significantly smaller than the free-breathing volumes [23 % reduction of planning tumour volume (PTV), p = 0.002]. ABC allowed a reduction of all dosimetric parameters [2.28 % reduction of percentage volume of lung treated to a dose of ≥ 20 Gy (V20), p = 0.004; 10 % reduction of mean lung dose (MLD), p = 0.009]. Significant differences were found both in SRT and in 3D-CRT, in peripheral and apical lesions. CONCLUSION: In our experience, ABC has the potential to reduce lung toxicity in the treatment of lung cancer; alternatively, it can allow the prescribed dose to be increased while maintaining the same risk of lung toxicity.

Vinorelbine-based chemo-radiotherapy in non-small cell lung cancer.

AIMS AND BACKGROUND: Concomitant radio-chemotherapy improves survival of patients with locally advanced non-small cell lung cancer, with a better local-regional control. METHODS AND STUDY DESIGN: We report our experience with vinorelbine-based chemotherapy in neoadjuvant and radical settings in 43 patients. Regimens consisted of cisplatin plus vinorelbine in 74.4% patients and carboplatin plus vinorelbine in 14.0%; 11.6% underwent mono-chemotherapy with oral vinorelbine. We estimated the crude probability of death or local recurrence by the Kaplan-Meier method. Cox regression models were used to identify the main significant predictors of death or local recurrence. RESULTS: A significant effect of the response to treatment was shown on both local disease free-survival (P = 0.004) and overall survival (P <0.0001). Patients with progressive disease after primary treatment had a significantly higher risk of further relapse at both univariate (P = 0.046) and multivariate regression analysis (P = 0.014) than patients with a complete response. They also showed a significantly higher risk of death at both univariate (P = 0.0005) and multivariate regression analysis (P <0.0001) than patients with a complete response. The most common toxicity was hematologic and gastroenteric. We recorded grade III/IV leukopenia in 11%, anemia in 6%, and esophagitis in 14% of the patients. CONCLUSIONS: Our experience showed that vinorelbine-based chemotherapy is an effective and safe regimen, in association with a platinum compound and thoracic radiotherapy.

Limited-stage small-cell lung cancer treated with early chemo-radiotherapy: the impact of effective chemotherapy.

AIMS AND BACKGROUND: Small cell lung cancer is characterized by an aggressive clinical course and a high sensitivity to both chemotherapy and radiotherapy. We present the Florence University experience in concurrent early radio-chemotherapy in patients affected by limited-stage small cell lung cancer, with particular emphasis on treatment safety, disease outcome and prognostic factors. METHODS AND STUDY DESIGN: Fifty-seven patients were treated between June 2000 and February 2005. All patients underwent platinum-based chemotherapy, administered intravenously following two different regimens, for at least three cycles. Eighteen patients (31.6%) received epirubicin and ifosfamide in 3-week cycles alternating with etoposide and cisplatin, administered on day 1 to 3; 39 patients (68.4%) received etoposide and cisplatin. A total of 6 cycles were planned. Radiotherapy was administered concurrently to the first cycle of etoposide and cisplatin. RESULTS: Clinical stage (P = 0.036) and number of chemotherapy courses (P = 0.009) emerged as the only significant death predictors at univariate analysis. Number of chemotherapy courses persisted as a significant death predictor also at multivariate regression analysis, with a reduced death risk for 5-6 chemotherapy cycles in comparison to 3-4 cycles (hazard ratio, 0.44). At a mean follow up of 38.5 months (standard deviation, 3.24 years; range, 6-164 months), considering the best overall tumor response achieved at any time during the whole treatment period, we obtained 32 complete responses (56.1%), 23 partial responses (40.3%) and 2 stable diseases. CONCLUSIONS: Our analysis showed that concurrent early radio-chemotherapy in limited-stage small cell lung cancer treatment represents a safe and effective approach in patients. We confirmed the relevant impact on overall survival of effective chemotherapy delivery.

Análise do arco longitudinal medial em adolescentes usuárias de calçados de salto alto / Analysis of the medial longitudinal arch in adolescents users of high heeled shoes

O objetivo do estudo foi analisar a influência do calçado de salto alto no arco longitudinal medial (ALM) do pé de adolescentes. Fizeram parte do estudo 82 adolescentes entre 13 e 20 anos, sendo 54 não usuárias (grupo controle - GC) e 28 usuárias (grupo experimental - GE) de calçado de salto alto. Foram obtidas as impressões plantares de ambos os pés para análise do ALM, antes e depois do uso de um calçado de salto alto padronizado por um período de 30 minutos. As impressões plantares foram avaliadas pelo índice de Chippaux-Smirak (ICS) e pelo arco de Cavanagh & Rodgers (ICR). O teste de Shapiro-Wilks foi utilizado para a verificação da normalidade dos dados. Variáveis paramétricas pareadas foram tratadas com o Teste t de Student pareado e as não-paramétricas com o teste de Wilcoxon. As comparações não-pareadas foram realizadas com o teste t de Student para as variáveis paramétricas e o de Mann-Withney para as não-paramétricas, com nível de significância de 0,05. Houve diferença no ALM entre os lados direito e esquerdo apenas no GC antes do uso do calçado. Na comparação entre antes e depois do uso do sapato, notou-se diferença apenas no pé esquerdo do GC pelo ICS. Já entre GC e GE, não houve diferença. Apesar dos resultados não evidenciarem alterações no ALM, deve-se lembrar que esta é uma medida estática, sendo necessários estudos do componente dinâmico e do uso do calçado de salto crônico para correlacionar com os achados deste trabalho.

The aim of this study was to analyze the influence of high heeled shoes in foot´s medial longitudinal arch in adolescents. Eighty two female adolescents between 13 and 20 years old participated, being 54 non-users of high heleed shoes (control group - GC) and 28 usuaries (experimental group - GE). The footprints of both feet were collected to analyse the medial longitudinal arch (ALM), before and after 30 minutes using a shoe with heel high given by the examiner, an then evaluated by Chippaux-Smirak index (ICS) and Cavanagh & Rodgers Arch index (ICR). The Shapiro-Wilks test was performed to evaluate data normality. For paired comparisons, paired Student's t-test was used in case of parametric data, and the Wilcoxon test in non-parametric data. In non-paired comparisons was used the Student's t-test and the Mann-Whitney test with a level of significance of 0.05. There was a difference between right and left only in CG before the use of the shoe given by the examiner. Comparing before and after the use of this shoe, a difference was noticed only on left foot in CG by ICS. There wasn't any significative difference between CG and EG. Although the results haven´t shown changes in ALM, it must be remembered this is only a static measure, being necessary studies of the dinamic component and the chronic use of high heeled shoes to correlate with the findings of this work.

Post-operative radiotherapy in N2 non-small cell lung cancer: a retrospective analysis of 175 patients.

BACKGROUND AND PURPOSE: Post-operative radiotherapy (PORT) in radically resected non-small cell lung cancer (NSCLC) has the aim to reduce loco regional recurrence and to improve overall survival. PORT has been evaluated in several trials but indication to post-operative treatment in N2 patients is still debated. MATERIAL AND METHODS: We retrospectively analyzed 175 patients treated at University of Florence between 1988 and 2004 with completely resected NSCLC stages IIIA-IIIB, N2 disease. Surgery consisted in a lobectomy in 58.9% and in a bi-lobectomy or in a pneumonectomy in 41.1% of patients. One hundred and nineteen patients underwent PORT and 56 patients did not receive PORT (no-PORT). RESULTS: At a median follow-up of 27.6 months (range 4-233 months), we found a significant reduction in local recurrence (LR) in PORT group (log-rank test p=0.015; HR: 0.45; 95%CI: 0.24-0.87). No statistical difference were found in terms of overall survival (OS) (log-rank test p=0.92). Concerning other prognostic factors, male sex emerged as statistically significant (HR:4.33;1.04-18.02) on local progression free survival (LPFS) at univariate analysis. Acute and long-term toxicity was mild. CONCLUSION: Our retrospective analysis showed that PORT may improve local disease control in N2 NSCLC patients with an acceptable treatment-related toxicity.

Outcome after conservative surgery and breast irradiation in 5,717 patients with breast cancer: implications for supraclavicular nodal irradiation.

PURPOSE: To evaluate the outcome and predictive factors of patients who underwent breast-conserving surgery and adjuvant radiotherapy to the whole breast only, without supraclavicular nodal irradiation. METHODS AND MATERIALS: A total of 5,717 patients with pT1-T4 breast cancer were treated at the University of Florence. The median age of the patient population was 55 years (range, 30-80 years). All patients were followed for a median of 6.8 years (range, 1-27 years). Adjuvant chemotherapy was recommended in 1,535 patients (26.9%). Tamoxifen was prescribed in 2,951 patients (51.6%). The patients were split into three groups according to number of positive axillary nodes (PAN): P1, negative axillary lymph nodes; P2, one to three PAN; P3, more than three PAN. RESULTS: The P3 patients had a higher incidence of supraclavicular fossa recurrence (SFR) compared with P2 and P1 patients. However, the incidence of SFR in P3 patients was low (only 5.5%), whereas the incidence of distant metastases (DM) was 27.2%. Distant metastasis was the only independent prognostic factor for breast cancer survival. Additionally, in the subgroup of patients who developed local recurrence, DM was the most important death predictor. CONCLUSION: Our series suggests that isolated SFR in patients who did not receive supraclavicular radiotherapy is infrequent, as well as in those patients who have more than three PAN, and SFR seems not to influence the outcome, which depends on DM occurrence.

Non-pegylated liposomal doxorubicin in combination with cyclophosphamide or docetaxel as first-line therapy in metastatic breast cancer: a retrospective analysis.

AIMS AND BACKGROUND: Anthracyclines such as doxorubicin play a central role in the management of advanced breast cancer. Unfortunately, the clinical benefits of anthracyclines are limited by cardiotoxicity that can lead to the development of potentially fatal congestive heart failure. In order to limit anthracycline-related cardiotoxicity, liposomal formulations of doxorubicin have been developed. This retrospective analysis evaluated the experience obtained with non-pegylated liposomal doxorubicin as first-line therapy in 34 patients with metastatic breast cancer. METHODS: Patients received non-pegylated liposomal doxorubicin in combination with either cyclophosphamide (n = 14) or docetaxel (n = 20) for up to eight cycles, and efficacy and safety were assessed according to standard criteria. RESULTS: The overall response rate was 71%. The median progression-free survival was 8 months in patients receiving non-pegylated liposomal doxorubicin plus cyclophosphamide and 13.8 months in those receiving non-pegylated liposomal doxorubicin plus docetaxel (P = 0.2). The most commonly observed toxicities were grade 1-2 leucopenia, alopecia, nausea and vomiting; no grade 3-4 toxicities were observed. Overall, three patients (9%) experienced grade 1 cardiac toxicity. CONCLUSIONS: Our results support the use of non-pegylated liposomal doxorubicin as an alternative to conventional doxorubicin formulations in combination regimens for the first-line therapy of metastatic breast cancer.

Alternating intravenous and oral vinorelbine plus epirubicin with pegfilgrastim as neoadjuvant treatment of locally advanced breast cancer.

In order to downstage locally advanced breast cancer, neoadjuvant chemotherapy consisting of intravenous vinorelbine 25 mg/m plus epirubicin 75 mg/m given on day 1 and oral vinorelbine 60 mg/m on day 8 was administered every 3 weeks for four courses. On day 2, all patients received a single subcutaneous injection of pegfilgrastim (6 mg). From March 2004 to June 2005, 22 patients were enrolled. Patients characteristics were: median age, 53 years (range: 39-70 years); postmenopausal, 7/22; clinical TNM stage, T2 (n=14), T3 (n=8), N0 (n=17) and N1 (n=5). The median number of courses was four (range: two to six courses) with full dose intensity. National Cancer Institute grade 3 haematological toxicities observed were neutropenia in 9% of patients, anaemia in 13% of patients and thrombocytopenia in 9% of patients; no toxicity grade 4 occurred. Two patients (9%) registered grade 2 polyneuropathy; no cardiac failure was observed. Conservative surgery was performed in 14 patients (63%). All patients were evaluable for response: complete pathological response was documented in three patients (13.6%); three patients (13.6%) obtained more than 75% of tumour size reduction; 11 other patients (50%) had 50% of tumour size reduction; stable disease was observed in five patients (22.7%). The present findings indicate that vinorelbine in combination with epirubicin is an effective and safe treatment in locally advanced breast cancer: this regimen obtained more than 50% of tumour size reduction in 77% of patients; the use of pegfilgrastim allowed full dose intensity. Oral vinorelbine on day 8 offers greater convenience to the patient by reducing the need for intravenous injection and the time spent in hospital.

Accelerated intensity-modulated external radiotherapy as a new technical approach to treat the index quadrant after conserving surgery in early breast cancer: a preliminary study.

PURPOSE: We present a novel technical approach to treat the index quadrant after conserving surgery in patients with early breast cancer and study its clinical feasibility. METHODS AND MATERIAL: Patients selected for the study, after breast conserving surgery with histologically verified breast carcinoma, signed a full informed consent to intensity-modulated external radiotherapy of the partial breast. Treatment was performed with the 6 MV beam from one of the Elekta Precise LINAC units installed in our Department. The prescribed dose was 30 Gy in 5 fractions in 10 days. RESULTS: Acute toxicity was minimal. No skin changes were noted during treatment or during the first 6 months after radiotherapy treatment. CONCLUSIONS: Accelerated partial breast irradiation using intensity-modulated external radiotherapy is technically feasible. We think the approach will give good results in terms of local control, toxicity and quality of life, at the same time sparing resources for the patient and health care system.
