RESUMEN
INTRODUCTION: We conducted an online survey to investigate oncologists' clinical practices and views on palliative care at the end of life in the Italian region of Liguria. METHODS: The survey included 29 items divided into three sections: participant characteristics (n=6), hospital resources and practices (n=11), participant practices and views (n=12). RESULTS: Twenty-one of the 41 medical oncologists invited completed the survey (51%). Although almost all reported the presence of palliative medicine physicians at their hospitals (90%), nearly half (48%) stated that palliative medicine physicians were not responsible for managing cancer patients at end of life, and 21% reported routine participation of palliative medicine physicians in multidisciplinary meetings. Thirty-eight percent of the respondents stated they never consulted psychologists regarding end of life patient care, and 43% reported they rarely did. Notably, a substantial proportion of participants stated that they administered active treatments to patients with six months life expectancy. Regarding integration between oncology and palliative medicine, an equal proportion felt it had been fully (48%) or partially achieved (48%) at their hospitals. CONCLUSIONS: Participants seemed fairly satisfied with the level of integration between oncology and palliative medicine at their hospitals, which contrasts with other findings regarding, for instance, the scant participation of palliative medicine physicians in multidisciplinary meetings. Exploring the impact of the novel regional clinical healthcare pathway for palliative care on practices at hospitals in Liguria will be crucial to ensure that cancer patients at end of life receive quality care.
RESUMEN
The raising number of older patients who are diagnosed with breast cancer represents a significant medical and societal challenge. Aromatase inhibitors (AI), which are commonly utilized to treat this condition in these patients have significant adverse events on bone and muscle health. Falling estrogen production leads to an increase in RANKL secretion by osteoblasts with accelerated bone remodeling due to osteoclast activity. Furthermore, estrogen deficiency reduces skeletal muscle strength and mass. The humanized monoclonal antibody, denosumab, neutralizes RANKL, thereby inhibiting osteoclast formation, function and survival and ultimately exerting powerful anti-resorptive effects.. In this study, we report on the efficacy of denosumab in mitigating aromatase inhibitor-induced bone loss (AIBL) and sarcopenia in older women with breast cancer. From January 2022 to January 2023, we enrolled 30 patients (female sex, ≥ 65 years) diagnosed with non-metastatic breast cancer undergoing adjuvant endocrine therapy; patients received, as per clinical practice, primary bone prophylaxis with denosumab (60 mg via subcutaneous injection every 6 months) according to oncologic guidelines. This group was matched with 30 patients with non-metastatic breast cancer, who were treated with biphosphonates (BF) therapy (oral alendronate 70 mg/week). For each patient bone mineral density (BMD) and bone quality in terms of trabecular bone score (TBS) in addition to body composition and Relative Skeletal Muscle Index (RSMI) was assessed by bone densitometry at baseline and after one year of treatment. Significant improvements in TBS at the lumbar spine, RSMI and whole-body composition (arms, legs, and trunk) were observed in the denosumab group compared with the BF group. These findings underscore the role of denosumab as an effective strategy in managing AIBL and osteosarcopenia in older women with breast cancer and undergoing adjuvant endocrine therapy, which is crucial for improving quality of life, preventing functional decline, and optimizing treatment outcomes.
RESUMEN
OBJECTIVES: To better understand the type of care offered to Italian patients with advanced breast cancer at the End-of-Life (EoL), we conducted a retrospective observational study. EoL was defined as the period of six months before death. METHODS: One hundred and twenty-one patients with advanced breast cancer (ABC) treated at IRCCS San Martino Policlinic Hospital who died between 2017 and 2021 were included. Data about patient, disease, and treatment characteristics from breast cancer diagnosis to death, along with information about comorbidities, medications, imaging, specialist evaluations, hospitalization, palliative care and home care, hospice admissions, and site of death were collected. RESULTS: 98.3% of the patients received at least one line of active treatment at EoL; 52.8% were hospitalized during the selected period. Palliative (13.9%), psychological (7.4%), and nutritional evaluations (8.2%) were underutilized. Palliative home care was provided to 52% of the patients. Most of the patients died at home (66.1%) and fewer than one out of five (18.2%) died at the hospital. Among the patients who died at home, 27.3% had no palliative support. CONCLUSIONS: Our findings indicate that palliative care in EoL breast cancer patients is still inadequate. Only a minority of patients had psychological and nutritional support While low nutritional support may be explained by the fact that typical symptoms of ABC do not involve the gastrointestinal tract, the lack of psychological support suggests that significant barriers still exist. Data on the site of death are encouraging, indicating that EoL management is increasingly home centered in Italy.

To evaluate the rate of early breast cancer (EBC) patients treated with neoadjuvant systemic therapy (NAT) in Italy, criteria of patient selection and types of therapies delivered, an analysis of 1276 patients with stage I-II-III was conducted out of 1633 patients enrolled in the multicenter prospective observational BRIDE study. A total of 177 patients (13.9%) were treated with NAT and 1099 (85.9%) with surgery; in multivariate analysis, menopausal status, cT, cN, grade, HER2-positive and Triple negative (TN) subgroups were significantly associated with the decision to administer NAT. The type of NAT delivered was influenced by EBC subtype. NAT was administered to 53.2% of HER2+/HR-negative, 27.9% of HER2+/HR+, 7.1% of HER2-negative/HR+ and 30.3% of TN EBC patients. The pCR rates were similar to the ones reported in the literature: 74.2% in HER2+/HR-negative, 52.3% in HER2+/HR+, 17.2% in HER2-negative/HR+ and 37.9% in TN. In clinical practice, patient and tumor characteristics influenced oncologists in the decision to administer NAT in EBC and in the choice of the type of systemic therapy, according to ESMO and AIOM Guidelines. Currently, it is recommended always to evaluate the use of NAT in EBC, mainly in HER2+ and TN patients, considering that pCR is associated with significantly better survival of the patient and that effective therapies are now available for residual disease.
RESUMEN
BACKGROUND: Treatment for HER2-positive (+) metastatic breast cancer has improved in the last decade. We analyzed treatment changes over time and their impact on patients outcomes in a real-world dataset. METHODS: Data from 637 HER2+ patients with metastatic breast cancer enrolled in the multicenter Italian GIM14/BIOMETA study were retrieved. Progression-free survival (PFS) over time was evaluated according to the type of anti-HER2 therapy, disease onset (de novo vs. relapsing), metastatic site, and year of treatment (2000-2013 vs. 2014-2020). RESULTS: Median follow-up was 64.4 months. Overall, for first-line therapies, mPFS was 16.5 vs 19.5 months for patients treated in 2000-2013 vs 2014-2020 (HR: 0.78, 95% CI:0.65-0.94, P = 0.008). mPFS improved over time in all patients except for those with brain metastasis. Interestingly mPFS was 17.4 vs13.4 months (HR, 1.49; 95% CI, 1.13-1.98, P = 0.005) in 2000-2013 and 24.4 vs 20.9 months (HR 1.04; 95% CI 0.78-1.40 p = 0.77) in 2014-2020 in pts without vs with liver metastases. For second line therapies, the overall median PFS was 9.6 months (95% CI, 8.31-10.97) and did not change over time. CONCLUSION: Median first-line PFS improved since 2014, mainly due to the introduction of pertuzumab. The outcome of patients with liver metastases appears to have improved in recent years. Patients with brain metastases had the worst PFS, which also did not improve over time.

PURPOSE: In estrogen receptor-positive (ER+) breast cancer, single-nucleotide polymorphisms (SNP) in the aromatase gene might affect aromatase inhibitors (AI) metabolism and efficacy. Here, we assessed the impact of SNP on prognosis and toxicity of patients receiving adjuvant letrozole. EXPERIMENTAL DESIGN: We enrolled 886 postmenopausal patients in the study. They were treated with letrozole for 2 to 5 years after taking tamoxifen for 2 to 6 years, continuing until they completed 5 to 10 years of therapy. Germline DNA was genotyped for SNP rs4646, rs10046, rs749292, and rs727479. Log-rank test and Cox model were used for disease-free survival (DFS) and overall survival (OS). Cumulative incidence (CI) of breast cancer metastasis was assessed through competing risk analysis, with contralateral breast cancer, second malignancies and non-breast cancer death as competing events. CI of skeletal and cardiovascular events were assessed using DFS events as competing events. Subdistribution HR (sHR) with 95% confidence intervals were calculated through Fine-Gray method. RESULTS: No SNP was associated with DFS. Variants rs10046 [sHR 2.03, (1.04-2.94)], rs749292 [sHR 2.11, (1.12-3.94)], and rs727479 [sHR 2.62, (1.17-5.83)] were associated with breast cancer metastasis. Three groups were identified on the basis of the number of these variants (0, 1, >1). Variant-based groups were associated with breast cancer metastasis (10-year CI 2.5%, 7.6%, 10.7%, P = 0.035) and OS (10-year estimates 96.5%, 93.0%, 89.6%, P = 0.030). Co-occurrence of rs10046 and rs749292 was negatively associated with 10-year CI of skeletal events (3.2% vs. 10%, P = 0.033). A similar association emerged between rs727479 and cardiovascular events (0.3% vs. 2.1%, P = 0.026). CONCLUSIONS: SNP of aromatase gene predict risk of metastasis and AI-related toxicity in ER+ early breast cancer, opening an opportunity for better treatment individualization.

OBJECTIVE: Neoadjuvant chemotherapy has become the preferred treatment in HER2-positive early breast cancer. Several trials investigated the neoadjuvant efficacy of dual HER2 blockade with anthracycline-free chemotherapy, whereas few data are available on single-agent trastuzumab and anthracycline-based regimens, which represent the standard of care in the adjuvant setting. This phase II, single-arm trial assessed anthracycline-based chemotherapy and trastuzumab as neoadjuvant treatment for high-risk HER2-positive breast cancer. METHODS: Forty-three patients with stage II-III HER2-positive breast cancer were treated with 4 courses of neoadjuvant 5-fluorouracil 600 mg/m2, epirubicin 90 mg/m2, cyclophosphamide 600 mg/m2 (FEC ×4) every 21 days, followed by 12 courses of weekly paclitaxel 80 mg/m2 and trastuzumab 2 mg/Kg IV (loading dose 4 mg/kg). RESULTS: Pathologic complete response (pCR) was observed in 22 (51%) of 43 patients. After a median follow-up of 6 years, the 5-year disease-free survival and overall survival were 85.8% (95% confidence interval 75.9%-97%) and 89.6% (80.4%-99.8%), respectively. A temporary decrease in left ventricular ejection fraction was observed in two patients. No cardiac death or congestive heart failure occurred. One patient died due to febrile neutropenia. CONCLUSIONS: FEC ×4 followed by paclitaxel and trastuzumab was associated with high pCR rates and favorable long-term outcomes. However, this regimen was associated with relevant hematologic toxicity.

BACKGROUND: Previous analyses of the GIM (Gruppo Italiano Mammella) 2 study showed that addition of fluorouracil to epirubicin, cyclophosphamide, and paclitaxel in patients with node-positive early breast cancer does not improve outcome, whereas dose-dense chemotherapy induces a significant improvement in both disease-free survival and overall survival as compared with a standard schedule. Here, we present long-term results of the study. METHODS: In this 2â×â2 factorial, open-label, randomised, phase 3 trial, we enrolled patients aged 18-70 years with operable, node-positive, breast cancer with Eastern Cooperative Oncology Group performance status of 0-1 from 81 hospitals in Italy. Eligible patients were randomly allocated (1:1:1:1) to one of the four following study groups: four cycles of standard-interval intravenous EC (epirubicin 90 mg/m2 and cyclophosphamide 600 mg/m2) on day 1 every 3 weeks, followed by four cycles of intravenous paclitaxel (175 mg/m2) on day 1 every 3 weeks (q3EC-P group); four cycles of intravenous FEC (fluorouracil 600 mg/m2, epirubicin 90 mg/m2, and cyclophosphamide 600 mg/m2) on day 1 every 3 weeks, followed by four cycles of intravenous paclitaxel (175 mg/m2) on day 1 every 3 weeks (q3FEC-P group); dose-dense EC-P regimen, with the same doses and drugs as the q3EC-P group but administered every 2 weeks (q2EC-P group); and the dose-dense FEC-P regimen, with the same doses and drugs as the q3FEC-P group but given every 2 weeks (q2FEC-P). Randomisation, with stratification by centre, with permuted blocks of size 12, was done with a centralised, interactive, internet-based system that randomly generated the treatment allocation. The primary endpoint was disease-free survival in the intention-to-treat population, comparing different chemotherapy schedule (dose-dense vs standard-dose intervals) and regimen (FEC-P vs EC-P). Safety population included all patients that received at least one dose of any study drug according to the treatment received. This trial is registered with ClinicalTrials.gov, NCT00433420, and is now closed. FINDINGS: Between April 24, 2003, and July 3, 2006, 2091 patients were randomly assigned to treatment: 545 to q3EC-P, 544 to q3FEC-P, 502 to q2EC-P, and 500 to q2FEC-P. 88 patients were enrolled in centres providing only standard interval schedule and were assigned only to q3FEC-P and q3EC-P; thus, 2091 patients were included in the intention-to-treat analysis for the comparison of EC-P (1047 patients) versus FEC-P (1044 patients) and 2003 patients were included in the intention-to-treat analysis for the comparison of dose-dense (1002 patients) versus standard interval analysis (1001 patients). After a median follow-up of 15·1 years (IQR 8·4-16·3), median disease-free survival was not significantly different between FEC-P and EC-P groups (17·09 years [95% CI 15·51-not reached] vs not reached [17·54-not reached]; unadjusted hazard ratio 1·12 [95% CI 0·98-1·29]; log-rank p=0·11). Median disease-free survival was significantly higher in the dose-dense interval group than the standard-interval group (not reached [95% CI 17·45-not reached] vs 16·52 [14·24-17·54]; 0·77 [95% CI 0·67-0·89]; p=0·0004). The most common grade 3-4 adverse events were neutropenia (200 [37%] of 536 patients in the q3EC-P group vs 257 [48%] of 533 in the q3FEC-P group vs 50 [10%] of 496 q2EC-P vs 97 [20%] of 492) and alopecia (238 [44%] vs 249 [47%] vs 228 [46%] vs 235 [48%]). During extended follow-up, no further grade 3-4 adverse events or deaths related to toxic-effects were reported. Treatment-related serious adverse events were reported in nine (2%) patients in the q3EC-P group, seven (1%) in the q3FEC-P group, nine (2%) in the q2EC-P group, and nine (2%) in the q2FEC-P group. No treatment-related deaths occurred. INTERPRETATION: Updated results from the GIM2 study support that optimal adjuvant chemotherapy for patients with high-risk early breast cancer should not include fluorouracil and should use a dose-dense schedule.

The SARS-CoV-2 health emergency has demonstrated the need for developing structured telemedicine systems to protect citizens from the spread of the virus. Thereby, their importance and the necessity to tailor their diffusion at large scale for providing services both at a distance and in time has been shown. For these reasons, the European Union advocates the digital transition of health systems for the next 5 years. The main aim of this work is to revisit the telemedicine research projects financed by European Community during the period 2000-2020 with particular respect to the results derived from their application. The analysis showed that some integration of tele-care and tele-health could be obtained with tele-monitoring systems and the implementation of Electronic Personal Record (EPR). Furthermore, telemedicine allows enhancing health care in critical environments, to protect health and life of the most vulnerable patients, and to encourage cross-border dialogue. The criteria of "from distance" and "timely delivered" are granted, but the effectiveness of the overall offered services highly depends on the availability and the quality of the input data. Unfortunately, this remains a relevant problem in the SARS-CoV-2 pandemic.
RESUMEN
BACKGROUND: Although use of gonadotropin-releasing hormone agonist (GnRHa) during chemotherapy is an established strategy to protect ovarian function in premenopausal breast cancer patients, no long-term safety data are available, raising some concerns in women with hormone receptor-positive disease. There are controversial data on its fertility preservation potential. METHODS: The Prevention of Menopause Induced by Chemotherapy: a Study in Early Breast Cancer Patients-Gruppo Italiano Mammella 6 (PROMISE-GIM6) trial is a multicenter, randomized, open-label, phase III superiority trial conducted at 16 Italian centers from October 2003 to January 2008. Eligible patients were randomly assigned to (neo)adjuvant chemotherapy alone (control arm) or combined with the GnRHa triptorelin (GnRHa arm). The primary planned endpoint was incidence of chemotherapy-induced premature ovarian insufficiency. Post hoc endpoints were disease-free survival (DFS), overall survival (OS), and post-treatment pregnancies. Hazard ratios (HRs) and 95% confidence intervals (CIs) were calculated. RESULTS: Of 281 randomly assigned patients, 80.4% had hormone receptor-positive breast cancer. Median follow-up was 12.4 years (interquartile range = 11.3-13.2 years). No differences in 12-year DFS (65.7% [95% CI = 57.0% to 73.1%] in the GnRHa arm vs 69.2% [95% CI = 60.3% to 76.5%] in the control arm; HR = 1.16, 95% CI = 0.76 to 1.77) or in 12-year OS (81.2% [95% CI = 73.6% to 86.8%] in the GnRHa arm vs 81.3% [95% CI = 73.1% to 87.2%] in the control arm; HR = 1.17, 95% CI = 0.67 to 2.03) were observed. In patients with hormone receptor-positive disease, the hazard ratio was 1.02 (95% CI = 0.63 to 1.63) for DFS and 1.12 (95% CI = 0.59 to 2.11) for OS. In the GnRHa and control arms, 9 and 4 patients had a posttreatment pregnancy, respectively (HR = 2.14, 95% CI = 0.66 to 6.92). CONCLUSIONS: Final analysis of the PROMISE-GIM6 trial provides reassuring results on the safety of GnRHa use during chemotherapy as a strategy to preserve ovarian function in premenopausal patients with early breast cancer, including those with hormone receptor-positive disease.

BACKGROUND: The benefit of extending aromatase inhibitor therapy beyond 5 years in the context of previous aromatase inhibitors remains controversial. We aimed to compare extended therapy with letrozole for 5 years versus the standard duration of 2-3 years of letrozole in postmenopausal patients with breast cancer who have already received 2-3 years of tamoxifen. METHODS: This multicentre, open-label, randomised, phase 3 trial was done at 69 hospitals in Italy. Women were eligible if they were postmenopausal at the time of study entry, had stage I-III histologically proven and operable invasive hormone receptor-positive breast cancer, had received adjuvant tamoxifen therapy for at least 2 years but no longer than 3 years and 3 months, had no signs of disease recurrence, and had an Eastern Cooperative Oncology Group performance status of 2 or lower. Patients were randomly assigned (1:1) to receive 2-3 years (control group) or 5 years (extended group) of letrozole (2·5 mg orally once a day). Randomisation, with stratification by centre, with permuted blocks of size 12, was done with a centralised, interactive, internet-based system that randomly generated the treatment allocation. Participants and investigators were not masked to treatment assignment. The primary endpoint was invasive disease-free survival in the intention-to-treat population. Safety analysis was done for patients who received at least 1 month of study treatment. This trial was registered with EudraCT, 2005-001212-44, and ClinicalTrials.gov, NCT01064635. FINDINGS: Between Aug 1, 2005, and Oct 24, 2010, 2056 patients were enrolled and randomly assigned to receive letrozole for 2-3 years (n=1030; control group) or for 5 years (n=1026; extended group). After a median follow-up of 11·7 years (IQR 9·5-13·1), disease-free survival events occurred in 262 (25·4%) of 1030 patients in the control group and 212 (20·7%) of 1026 in the extended group. 12-year disease-free survival was 62% (95% CI 57-66) in the control group and 67% (62-71) in the extended group (hazard ratio 0·78, 95% CI 0·65-0·93; p=0·0064). The most common grade 3 and 4 adverse events were arthralgia (22 [2·2%] of 983 patients in the control group vs 29 [3·0%] of 977 in the extended group) and myalgia (seven [0·7%] vs nine [0·9%]). There were three (0·3%) serious treatment-related adverse events in the control group and eight (0·8%) in the extended group. No deaths related to toxic effects were observed. INTERPRETATION: In postmenopausal patients with breast cancer who received 2-3 years of tamoxifen, extended treatment with 5 years of letrozole resulted in a significant improvement in disease-free survival compared with the standard 2-3 years of letrozole. Sequential endocrine therapy with tamoxifen for 2-3 years followed by letrozole for 5 years should be considered as one of the optimal standard endocrine treatments for postmenopausal patients with hormone receptor-positive breast cancer.

BACKGROUND: Offering ovarian function and/or fertility preservation strategies in premenopausal women with newly diagnosed breast cancer candidates to undergo chemotherapy is standard of care. However, few data are available on uptake and main reasons for refusing these options. METHODS: The PREFER study (NCT02895165) is an observational, prospective study enrolling premenopausal women with early breast cancer, aged between 18 and 45 years, candidates to receive (neo)adjuvant chemotherapy. Primary objective is to collect information on acceptance rates and reasons for refusal of the proposed strategies for ovarian function and/or fertility preservation available in Italy. RESULTS: At the study coordinating center, 223 patients were recruited between November 2012 and December 2020. Median age was 38 years (range 24 - 45 years) with 159 patients (71.3%) diagnosed at ≤40 years. Temporary ovarian suppression with gonadotropin-releasing hormone agonists (GnRHa) was accepted by 58 out of 64 (90.6%) patients aged 41-45 years and by 151 out of 159 (95.0%) of those aged ≤40 years. Among patients aged ≤40 years, 57 (35.8%) accepted to access the fertility unit to receive a complete oncofertility counseling and 29 (18.2%) accepted to undergo a cryopreservation technique. Main reasons for refusal were fear of delaying the initiation of antineoplastic treatments and contraindications to the procedure or lack of interest in future childbearing. Patients with hormone-receptor positive breast cancer had a tendency for a higher acceptance rates of ovarian function and/or fertility preservation strategies than those with hormone-receptor negative disease. CONCLUSIONS: More than 90% of premenopausal women with early breast cancer, and particularly those with hormone receptor-positive disease, were concerned about the potential risk of chemotherapy-induced premature ovarian insufficiency and/or infertility and accepted GnRHa administration. Less than 1 out of 5 women aged ≤40 years accepted to undergo cryopreservation strategies.
RESUMEN
The GIM2 phase III trial demonstrated the benefit of dose-dense chemotherapy in node-positive early breast cancer (eBC). To better define the dose-dense effect in the hormone receptor-positive subgroup, we evaluated its benefit through a composite measure of recurrence risk. We conducted an ancillary analysis of the GIM2 trial evaluating the absolute treatment effect through a composite measure of recurrence risk (CPRS) in patients with hormone receptor-positive HER2-negative eBC. CPRS was estimated through Cox proportional hazards models applied to the different clinicopathological features. The treatment effect was compared to the values of CPRS by using the Sub-population Treatment Effect Pattern Plot (STEPP) process. The Disease-Free Survival (DFS)-oriented STEPP analysis showed distinct patterns of relative treatment effect with respect to CPRS. Overall, 5-year DFS differed across CPRS quartiles ranging from 95.2 to 66.4%. Each CPRS quartile was characterized by a different patients' composition, especially for age, lymph node involvement, tumor size, estrogen and progesterone receptor expression, and Ki-67. A number needed to treat of 154 and 6 was associated with the lowest and the highest CPRS quartile, respectively. Dose-dense adjuvant chemotherapy showed a consistent benefit in node-positive eBC patients with hormone receptor-positive HER2-negative disease, but its effect varied according to CPRS.
RESUMEN
BACKGROUND: In the prepertuzumab era, we evaluated the clinical outcomes of patients with human epidermal growth factor receptor 2 (HER2)-positive metastatic breast cancer who underwent first-line trastuzumab-based or lapatinib-based therapy according to prior exposure to (neo)adjuvant trastuzumab. MATERIALS AND METHODS: In this multicentre retrospective cohort study conducted in 14 Italian centres of the Gruppo Italiano Mammella, consecutive patients undergoing first-line trastuzumab or lapatinib-based therapy were included. Analyses were performed according to the type of first-line therapy for metastatic disease (trastuzumab or lapatinib). Dichotomous clinical outcomes were analysed using logistic regression and time-to-event outcomes using Cox proportional hazard models controlling for relevant demographic, clinicopathological and therapy characteristics. RESULTS: Out of 450 patients included in the study, 416 (92%) received trastuzumab and 34 (7.5%) lapatinib. As compared with the trastuzumab cohort, more patients in the lapatinib cohort had a trastuzumab-free interval <1 month (37% vs 13.9%; p=0.017) and brain metastasis as first site of relapse (38.2% vs 9.4%; p<0.001). Among the 128 patients who relapsed after prior (neo)adjuvant trastuzumab, 101 (78.9%) received first-line trastuzumab and 27 (21.1%) first-line lapatinib. The following outcomes were observed with first-line lapatinib or trastuzumab, respectively: overall response rate 45.5% vs 61.3% (p=0.184), clinical benefit rate 68.2% vs 72.5% (p=0.691), median progression-free survival (PFS) 11.4 vs 12.0 months (p=0.814) and median overall survival (OS) 34.7 vs 48.2 months (p=0.722). In patients with brain metastasis as first site of relapse, median PFS was 12.2 vs 9.9 months (p=0.093) and median OS 33.7 vs 28.5 months (p=0.280), respectively. CONCLUSIONS: In patients with HER2-positive breast cancer relapsing after prior (neo)adjuvant trastuzumab, first-line treatment with trastuzumab or lapatinib was not associated with a significant difference in the clinical outcomes. A non-significant trend favouring the use of lapatinib was observed in patients with brain metastasis as the first site of relapse.

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.

BACKGROUND: Adjuvant chemotherapy is the standard of care in high-risk early breast cancer patients. Dose-dense should be the preferred schedule of administration. However, its long-term benefit is unknown. METHODS: In the Italian multicentre Phase 3 randomised MIG-1 trial, node-positive and high-risk node- negative breast cancer patients were randomised to receive six cycles of adjuvant fluorouracil, epirubicin and cyclophosphamide regimen administered every 3 (FEC21) or 2 (FEC14) weeks. The primary endpoint was overall survival (OS), and the secondary endpoint was event-free survival (EFS). RESULTS: From 1992 to 1997, 1214 patients were included. Median follow-up was 15.8 years. In all, 15-year OS was 71% and 68% in the FEC14 and FEC21 groups, respectively (HR = 0.89; p = 0.25). In all, 15-year EFS was 47% and 43% in the FEC14 and FEC21 groups, respectively (HR = 0.87; p = 0.18). In a pre-planned subgroup analysis, among patients with hormone receptor-negative tumours, 15-year OS was 70% and 65% in the FEC14 and FEC21 groups, respectively (HR = 0.73; 95% CI: 0.51-1.06); 15-year EFS was 58% and 43% in the FEC14 and FEC21 groups, respectively (HR = 0.70; 95% CI: 0.51-0.96). CONCLUSIONS: Updated results from the MIG-1 study are numerically in favour of dose-dense chemotherapy, and suggest a long-term benefit of this approach in high-risk early breast cancer patients.

Dose-dense adjuvant chemotherapy is standard of care in high-risk early breast cancer patients. However, its role in HER2-positive patients is still uncertain. In this exploratory analysis of the GIM2 trial, we investigated the efficacy of dose-dense chemotherapy in HER2-positive breast cancer patients with or without exposure to trastuzumab. In the GIM2 trial, node-positive early breast cancer patients were randomized to receive four cycles of (fluorouracil)epirubicin/cyclophosphamide followed by four cycles of paclitaxel administered every 2 (dose-dense) or 3 (standard-interval) weeks. After approval of adjuvant trastuzumab, protocol was amended in April 2006 to allow use of trastuzumab for 1 year after chemotherapy completion in HER2-positive patients. The efficacy of dose-dense chemotherapy in terms of disease-free survival (DFS) and overall survival (OS) was assessed according to HER2 status and trastuzumab use. Out of 2,003 breast cancer patients, HER2 status was negative/unknown in 1,551 patients; among the 452 patients with HER2-positive breast cancer, chemotherapy alone or followed by trastuzumab was given to 320 and 132 patients, respectively. Median follow-up was 8.1 years. No significant interaction between HER2 status, trastuzumab use and chemotherapy treatment was observed for both DFS (p = 0.698) and OS (p = 0.708). Nevertheless, there was no apparent benefit in the HER2-positive group treated with trastuzumab (DFS: HR, 0.99; 95% CI 0.52-1.89; OS: HR, 0.95; 95% CI 0.37-2.41). Although dose-dense chemotherapy was associated with a significant survival improvement in high-risk breast cancer patients, its benefit appeared to be smaller (if any) in patients with HER2-positive disease who received adjuvant trastuzumab.

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.

The use of chemotherapy in premenopausal cancer patients may lead to chemotherapy-induced premature ovarian failure. Pharmacological temporary ovarian suppression obtained with the gonadotropin-releasing hormone agonist (GnRHa) administered concomitantly with chemotherapy has been investigated as a technique capable to reduce the gonadotoxicity, reducing the risk of developing premature menopause. In recent years, important evidence has become available on the efficacy and safety of this strategy that should now be considered a standard option for ovarian function preservation in premenopausal breast cancer patients. However, in women interested in fertility preservation, this is not an alternative to cryopreservation strategies, which remains the first option to be proposed. The purpose of this review is to summarize the mechanisms of GnRHa in the preservation of fertility in premenopausal cancer patient candidates to receive chemotherapy, highlighting the areas of doubt that require further investigation.
RESUMEN
Breast cancer is still the most frequent cancer diagnosed in women aged ≤40 years and the primary cause of death in this age group. The management of these patients needs a dedicated approach involving a multidisciplinary team that takes into account their treatment and survivorship issues. The present review aims to provide a perspective on the many challenges associated with treatment of young women with early breast cancer. We will focus on the standard (neo)adjuvant treatment, highlighting the paucity of age-specific results about the available genomic signatures, the groundbreaking landscape of adjuvant endocrine therapy and the relevant issue of the fertility preservation.
