RESUMEN
BACKGROUND: Luminal A-like and luminal B-like subtypes have different sensitivity to (neo)adjuvant chemotherapy, but their role in predicting dose-dense (DD) efficacy in the high-risk setting is unknown. In this exploratory analysis of the Gruppo Italiano Mammella 2 (GIM2) trial, we investigated DD efficacy according to luminal-like subtypes. METHODS: Patients with node-positive early breast cancer were randomised to receive either DD or standard-interval (SI) anthracycline-based chemotherapy followed by paclitaxel. In our analysis, luminal A-like cohort was identified as having a Ki67 < 20% and a progesterone receptor (PgR) ≥ 20%; luminal B-like cohort as having a Ki67 ≥ 20% and/or a PgR < 20%. RESULTS: Out of 2003 patients enrolled in the GIM2 trial, 412 had luminal A-like and 638 luminal B-like breast cancer. After a median follow-up of 7.9 years, disease-free survival (DFS) was 80.8% (95% confidence interval [CI] 76.4-84.5) and 70.5% (66.5-74.2) in luminal A-like and luminal B-like cohorts; overall survival (OS) was 91.6% (88.2-94.1) and 85.1% (81.7-87.9), respectively. We found no significant interaction between treatment and luminal subtype (interaction p = 0.603 and 0.535 for DFS and OS, respectively). When DD efficacy was investigated separately in each cohort, luminal-B like cohort appeared to benefit more from the DD schedule both in terms of DFS (unadjusted hazard ratio [HR] 0.72 [95% CI 0.54-0.96]) and OS (unadjusted HR 0.61 [95% CI 0.40-0.94]), compared with the luminal A-like cohort (unadjusted HR for DFS 0.89 [95% CI 0.59-1.33]; unadjusted HR for OS 0.83 [95% CI 0.45-1.54]). CONCLUSIONS: No significant interaction between luminal-like subtype and treatment was observed. Patients in the luminal B-like cohort seemed to benefit more from DD schedule.

Tamoxifen is frequently used as adjuvant treatment in premenopausal patients with hormone receptor-positive early breast cancer. According to guidelines, the use of nonhormonal barrier contraception is recommended during tamoxifen treatment and up to 3 months after its interruption prior to attempting conception. Nevertheless, when conception occurs inadvertently during tamoxifen treatment, the effects on the fetus and on the course of pregnancy are still not completely known. Here, we report 3 cases of young women who accidentally became pregnant while taking tamoxifen and perform a systematic review of the literature to provide more elements for better and clear multidisciplinary counselling of women facing this challenging situation.
RESUMEN
BACKGROUND: T-DM1 improves progression-free survival (PFS) and overall survival (OS) in patients with metastatic human epidermal growth factor receptor 2-positive (HER2+) breast cancer progressing on prior trastuzumab plus a taxane. A paucity of data is available on T-DM1 efficacy after dual anti-HER2 blockade with pertuzumab and trastuzumab plus a taxane, which represents the current first-line standard of care. The present study is a retrospective/prospective evaluation of the efficacy and activity of second-line T-DM1 after front-line pertuzumab-based therapy. PATIENTS AND METHODS: Eligible patients were identified within the Gruppo Italiano Mammella (GIM) 14/BIOMETA study, a retrospective/prospective multicenter study on treatment patterns and outcomes of patients with metastatic breast cancer (ClinicalTrials.gov Identifier: NCT02284581). We searched for patients who received second-line T-DM1 after taxane plus trastuzumab and pertuzumab between November 15, 2013 and May 31, 2018. We calculated median PFS, median time to treatment failure (TTF), prolonged duration of therapy (PDT), objective response rate (ORR), and 1-year OS. RESULTS: Of 445 patients with HER2+ metastatic breast cancer, 77 were eligible for the analysis. At a median follow-up of 7 months, median PFS was 6.3 months (95% confidence intervals [CI], 4.8-7.7 months), and median TTF was 6.2 months (95% CI, 4-8.6 months). More than one-third of patients (37.6%; n = 29) experienced PDT with an ORR of 27.1%. At data cutoff, the median OS was not reached, and the 1-year OS was 82%. CONCLUSIONS: Our results show meaningful activity of T-DM1 after front-line pertuzumab plus trastuzumab and a taxane, with about 27% of patients having an objective response and 40% of patients achieving durable disease control.

BACKGROUND: Despite the availability of different strategies for ovarian function and/or fertility preservation in young breast cancer patients candidates for chemotherapy, limited data are available on patients' actual need of these options. PATIENTS AND METHODS: The PREFER study is a prospective cohort study including premenopausal women with newly diagnosed early stage breast cancer between the age of 18 and 45 years and candidates for chemotherapy. The study aimed to investigate patients' preferences and their choices of the different available strategies for ovarian function and/or fertility preservation (i.e. acceptance rate) and reasons for refusal. RESULTS: A total of 131 consecutive patients referred from a single breast unit were included. Median age was 38.9 years with 92 patients (70.3%) diagnosed atâ¯≤â¯40 years. The majority of patients (122, 93.1%) were concerned about the risk of treatment-induced premature ovarian insufficiency (POI) and/or infertility. A total of 120 (91.6%) patients underwent temporary ovarian suppression with gonadotropin-releasing hormone agonists during chemotherapy for ovarian function preservation. Among patients with ≤40 years, only 11 (12.0%) decided to access cryopreservation strategies for fertility preservation. The main reason for not accessing the fertility unit was completion of family planning before breast cancer diagnosis; for patients who accessed the fertility unit, fear of the procedure was the main reason to refuse the proposed cryopreservation strategies. CONCLUSION: Despite the majority of young breast cancer patients are concerned about the risk of treatment-induced POI and/or infertility, only a limited number of them required to access the fertility unit to undergo cryopreservation strategies.

BACKGROUND: Fertility and pregnancy issues are of key importance for young breast cancer patients. Despite several advances in the field, there are still multiple unmet needs and barriers in discussing and dealing with these concerns. To address the significant challenges related to fertility and pregnancy issues, the PREgnancy and FERtility (PREFER) study was developed as a national comprehensive program aiming to optimize care and improve knowledge around these topics. METHODS: The PREFER study is a prospective cohort study conducted across several Italian institution affiliated with the Gruppo Italiano Mammella (GIM) group evaluating patterns of care and clinical outcomes of young breast cancer patients dealing with fertility and pregnancy issues. It is composed of two distinctive studies: PREFER-FERTILITY and PREFER-PREGNANCY. The PREFER-FERTILITY study is enrolling premenopausal patients aged 18-45 years, diagnosed with non-metastatic breast cancer, who are candidates to (neo)adjuvant chemotherapy and not previously exposed to anticancer therapies. The primary objective is to obtain and centralize data about patients' preferences and choices towards the available fertility preserving procedures. The success and safety of these strategies and the hormonal changes during chemotherapy and study follow-up are secondary objectives. The PREFER-PREGNANCY study is enrolling survivors achieving a pregnancy after prior history of breast cancer and patients diagnosed with pregnancy-associated breast cancer (PABC). The primary objectives are to obtain and centralize data about the management and clinical outcomes of these women. Patients' survival outcomes, and the fetal, obstetrical and paediatric care of their children are secondary objectives. For both studies, the initial planned recruitment period is 5 years and patients will remain in active follow-up for up to 15 years. The PREFER-FERTILITY study was first activated in November 2012, and the PREFER-PREGNANCY study in May 2013. DISCUSSION: The PREFER study is expected to support and improve oncofertility counseling in Italy, to explore the real need of fertility preserving procedures, and to acquire prospectively more robust data on the efficacy and safety of the available strategies for fertility preservation, on the management of breast cancer survivors achieving a pregnancy and of women with PABC (including the possible short- and long-term complications in their children). TRIAL REGISTRATION NUMBER: ClinicalTrials.gov identifier: NCT02895165 (Retrospectively registered in August 2016).

Introduction Although hormonal-therapy is the preferred first-line treatment for hormone-responsive, HER2 negative metastatic breast cancer, no data from clinical trials support the choice between hormonal-therapy and chemotherapy.Methods Patients were divided into two groups according to the treatment: chemotherapy or hormonal-therapy. Outcomes in terms of clinical benefit and median overall survival (OS) were retrospectively evaluated in the two groups. To calculate the time spent in chemotherapy with respect to OS in the two groups, the proportion of patients in chemotherapy relative to those present in either group was computed at every day from the start of therapy.Results From 1999 to 2013, 119 patients received first-line hormonal-therapy (HT-first group) and 100 first-line chemotherapy (CT-first group). Patients in the CT-first group were younger and with poorer prognostic factors as compared to those in HT-first group. Clinical benefit (77 vs 81%) and median OS (50.7 vs 51.1 months) were similar in the two groups. Time spent in chemotherapy was significantly longer during the first 3 years in CT-first group (54-34%) as compared to the HT-first group (11-18%). This difference decreased after the third year and overall was 28% in the CT-first group and 18% in the HT-first group.Conclusions The sequence first-line chemotherapy followed by hormonal-therapy, as compared with the opposite sequence, is associated with a longer time of OS spent in chemotherapy. However, despite the poorer prognostic factors, patients in the CT-first group had a superimposable OS than those in the HT-first group.

The study was designed to compare an anthracycline-containing regimen to a regimen combining both anthracycline and paclitaxel as adjuvant therapy for high-risk breast cancer patients. In this multicenter, randomized phase-III trial, node-positive early breast cancer patients were randomly assigned to receive either 6 cycles of FEC (5-fluorouracil 600 mg/m(2), epirubicin 60 mg/m(2) and cyclophosphamide 600 mg/m(2), day 1, every 3 weeks) or 4 cycles of EP (epirubicin 90 mg/m(2) and paclitaxel 175 mg/m(2), day 1, every 3 weeks). The primary endpoint was overall survival (OS). Secondary endpoints included toxicity and event-free survival (EFS). From 1996 to 2001, 1055 patients were enrolled. At a median follow-up of 12.8 years, 335 deaths had been recorded. The 10-year OS was 73 % (95 % CI 69-77) in the FEC arm and 74 % (95 % CI 70-78) in the EP arm (p = 0.405). The 10-year EFS was 51 % (95 % CI 45-56) in the FEC arm and 49 % (95 % CI 44-55) in the EP arm (p = 0.572). No difference in the hazard of death was observed (HR for EP 0.85, 95 % CI 0.68-1.06, p = 0.15). Patients treated with FEC experienced more frequently nausea and vomiting, stomatitis, and leukopenia as compared to patients treated with EP. Toxicities which occurred more frequently with EP were anemia, fever, myalgias, and neurotoxicity. Our study failed to demonstrate a superiority of an adjuvant treatment with four EP as compared to six FEC in node-positive breast cancer patients.

Interleukin (IL)-18 is a proinflammatory and immune-enhancing cytokine, which exerts antitumor effects in vivo, mediated by the induction of interferon (IFN)γ. We previously reported that IL-18 processing is defective in epithelial ovarian carcinoma (EOC) cells, which secrete an inactive precursor (pro-IL-18) in vitro. In addition, IL-18 was reported as a potential biomarker of EOC. Here, we further investigated its role as a serological marker in human EOC and addressed its possible biological activity in vivo. Our data indicate that immunoreactive IL-18 is increased in EOC patients' sera at diagnosis as compared with age-matched healthy women. IL-18 levels were higher in the ascitic fluids than in sera, suggesting a local production in the peritoneal cavity. Indeed, immunohistochemical analysis of tumors showed IL-18 expression in cytokeratine-positive neoplastic cells, although also scattered histiocytes and some lymphoid cells stained for IL-18. The detection of human IL-18 in sera and ascitic fluids of immunodeficient mice, orthotopically implanted with human EOC cells, further suggested that circulating IL-18 is tumor-derived. However, IL-18 is not an EOC specific biomarker, as increased serum levels were found also in some endometrial cancer patients. By means of a new monoclonal antibody, we characterized IL-18 present in the ascitic fluid as pro-IL-18, which is biologically inactive. Accordingly, IFNγ was not increased in EOC patients' sera and ascitic fluids and showed no correlation with IL-18 levels. Altogether these data indicate that IL-18 in EOC fluids is predominantly tumor-derived and that its lack of biological activity may represent a mechanism of tumor-escape.

Uterine smooth muscle tumors range from benign leiomyomata to low- and high-grade leiomyosarcomas. A leiomyosarcoma is a rare malignant smooth muscle tumor that infrequently metastasizes to the bone. In fact, initial presentation or recurrence as osseous metastases is extremely uncommon in patients with a history of leiomyosarcoma. On imaging, these bone lesions generally appear as lytic foci. The authors report here two cases of osteoblastic bone lesions in leiomyosarcoma of the uterus with predominant metastatic lesions localized in the bone.
RESUMEN
OBJECTIVES: Biological markers that reliably predict clinical and pathological response to primary systemic therapy may have considerable clinical potential; this study evaluated response compared to expression of ER, PgR and Her2, grading and Ki-67 proliferation index before and after neoadjuvant chemotherapy in patients with locally advanced breast cancer (LABC). PATIENTS AND METHODS: Fifty-five patients received neoadjuvant chemotherapy for LABC. The incidence of clinical and pathological responses was assessed with respect to basal clinical stage, absent/low vs. high ER and PgR status, low vs. high proliferation index, grading and Her2 overexpression. RESULTS: Overall, 30 patients (54%) underwent downstaging of their primary tumor; pathological complete remission was observed in only one patient with Her2 positive breast tumor. Patients with pre-treatment Ki-67 >20%, Her2 overexpression, T2b/T3 vs. T4 clinical stage achieved higher response rate. CONCLUSION: The future of neoadjuvant therapy lies in tailoring treatment to individual patients by identifying response predictors; although the number of patients reported is small, this study confirms that clinical stage at diagnosis, Ki-67 reduction and Her2 overexpression are predictive of tumor response to neoadjuvant regimens.

BACKGROUND AND OBJECTIVE: Anthracyclines are highly effective and widely used cytotoxic agents, but their application is often limited by cumulative dose-dependent cardiotoxicity. Dexrazoxane has been shown in several clinical trials to prevent the development of this serious toxicity. The aim of our study was to analyze the incidence of cardiac dysfunction over a 10-year period in patients with breast cancer who were treated with anthracycline-based regimens with addition of dexrazoxane, mainly in an adjuvant setting. METHODS: We conducted a retrospective analysis on a population of women with breast cancer treated at our institution between January 1993 and October 2003. We reviewed patients' medical records and data on patient characteristics, treatment history, and adverse events that were collected, starting from the time of first visit before starting therapy, with the use of software created and designed for clinical records management in our institution (1999 OK-DH). Patients underwent an ECG assessment prior to starting chemotherapy, and were clinically monitored for cardiac failure. Those who developed signs and symptoms suggestive of cardiac dysfunction underwent further ECG. If clinical findings indicated, echocardiography and further cardiologic investigations were performed. The main outcome measure was the development of signs and symptoms indicative of congestive heart failure (CHF). RESULTS: A total of 318 female patients were treated with an anthracycline (doxorubicin or epirubicin)-based combination chemotherapy regimen during this time, in most cases in the adjuvant setting (n = 285). Most patients (n = 302) had early-stage disease and only 16 women presented with metastatic disease with good life expectancy (at least 1 year). All patients received dexrazoxane 1000 mg/m(2) intravenously prior to anthracycline administration during each chemotherapy cycle. The median follow-up duration was 35 months. During this time, five patients (1.57%) developed signs and symptoms of CHF. No patient at our institution died of heart failure during the period analyzed. Dexrazoxane was well tolerated, with no reports of adverse events associated with this drug. CONCLUSIONS: The reported incidence of cardiotoxicity in this study represents a marked reduction compared with historical data for patients receiving anthracycline-based chemotherapy without dexrazoxane. Dexrazoxane appears to have a cardioprotective effect in women with early-stage or advanced breast cancer treated with anthracycline-based combination chemotherapy, mainly as an adjuvant treatment. Prospective, randomized, controlled clinical trials in adjuvant setting should be performed to confirm these results.

AIMS AND BACKGROUND: The purpose of this study was to review our experience with the combination of circadian chronomodulated 5-fluorouracil infusion in association with cisplatin in patients with locally advanced or metastatic cancer of the cervix in order to assess the activity and tolerability of the combination. METHODS: Twenty patients with locally advanced disease and 21 patients with metastatic or recurrent disease were treated from January 1995 to May 1999. 5-fluorouracil (600 mg/m2, days 1 to 5) was administered by a continuous circadian-shaped infusion employing an external programmable portable pump; cisplatinum (20 mg/m2) was infused days 1 through 5 i.v. over a 2-hr period. Response to treatment was evaluated after 3 and 6 cycles of therapy. Patients with locally advanced disease who achieved a clinical shrinkage of their tumor or were at least stable were submitted to surgery; pelvic radiotherapy was administered to patients with disease progression. RESULTS: Seven patients with locally advanced disease achieved a partial clinical response (overall response, 35%; 95% CI, 15.4-59.2), and 12 of 20 patients were submitted to surgery. Median progression-free and overall survival were 17 months and 36 months, respectively. Objective responses were observed in 9 of 21 patients with metastatic/recurrent disease (7 partial plus 2 minor responses: overall response 43%; 95% CI, 21.8-65.9). Median time to progression and overall survival were 5 and 17 months, respectively. CONCLUSIONS: Cisplatinum plus 5-fluorouracil chronomodulated infusion showed a moderate but definite activity and was well tolerated in both groups of patients. In consideration of clinical results comparable to more toxic and expensive regimens reported in the literature, the combination appears to be a reasonable option especially for women with metastatic/recurrent cervical carcinoma and a promising treatment in combination with definitive radiotherapy in patients with locally advanced disease.
