Is weight gain preventable in women with early breast cancer undergoing chemotherapy? A real-world study on dietary pattern, physical activity, and body weight before and after chemotherapy.

PURPOSE: We aimed to investigate the role of a lifestyle intervention and clinical and therapeutic factors for preventing weight gain in early breast cancer (BC) patients from one week before to 12 months after chemotherapy. METHODS: Dietary assessments were conducted by a trained dietician using a food-frequency questionnaire at each clinical assessment. Total energy, macronutrients intakes, and physical activity were estimated and the Mediterranean Diet Score (MDS) for adherence to Mediterranean diet was calculated. At each follow-up visit, patients were provided with dietary advices according to Mediterranean and Italian guidelines by a registered dietician, after evaluation of their food records. The associations of clinical characteristics, dietary pattern, and physical activity with weight gain were evaluated by multiple logistic regression, with weight gain ≥5% from baseline value as a dichotomous dependent variable. RESULTS: 169 early BC patients who met all follow-up visits and provided complete data were included in the analysis. From baseline to last assessment, weight loss (≥5% decrease from baseline value), stable weight, and weight gain were observed in 23.1%, 58%, and 18.9% women, respectively. Overall, a 0.68 kg mean decrease in women's weight (-1.1% from baseline) was observed. The risk of gaining weight increased for having normal weight/underweight at baseline, receiving hormone therapy, MDS worsening, and physical activity decreasing from baseline to last assessment. CONCLUSION: Providing simple suggestions on Mediterranean diet principles was effective for preventing weight gain in normal weight women and favoring weight loss in overweight and obese women.

Taste Alterations Do Not Affect Change in Food Habits and Body Weight in Breast Cancer Patients.

BACKGROUND/AIM: Chemotherapy-induced taste alterations (TAs) affect approximately 53-84% of breast cancer patients with significant consequences on flavor perception, possibly leading to food aversion and changes in daily dietary habits. The aim of this study was to investigate the relationship between TAs and changes in food habits and body weight among early breast cancer (EBC) patients undergoing adjuvant chemotherapy. PATIENTS AND METHODS: TAs were prospectively evaluated in 182 EBC patients from April 2014 to June 2018. TAs, dietary habits, and body weight were collected by a trained dietician. TAs were classified into different subtypes according to the following basic taste perception: metallic, sweet, bitter, salty, sour, and umami taste. RESULTS: During adjuvant chemotherapy, a significant reduction in the consumption of bread, breadsticks, red meat, fat salami, snacks, added sugar, milk, and alcoholic beverages was observed, regardless of TAs onset. No correlation between these dietary changes and different TAs subtypes was found. Body weight remained stable in most EBC patients (71.4%) and was not influenced by TAs onset and by different TAs subtypes. CONCLUSION: EBC patients change their dietary habits during adjuvant chemotherapy, mostly following the World Cancer Research Fund recommendations, irrespective of TAs onset and without affecting body weight.

Taste alterations during neo/adjuvant chemotherapy and subsequent follow-up in breast cancer patients: a prospective single-center clinical study.

PURPOSE: Dysgeusia and taste alterations (TAs) are side effects of cytotoxic chemotherapy and affect patients' quality of life; however, the prevalence, types, and duration of TAs and their potential relationship with other clinical disturbances are not well-described. Our primary aim was to prospectively evaluate the characteristics of TAs in early breast cancer (EBC) patients during (neo)adjuvant chemotherapy and up to 1 year after its completion. METHODS: From April 2014 to June 2018, 182 EBC patients entered the study and received (neo)adjuvant chemotherapy, mostly with taxane and anthracycline-containing regimens (65% of cases). A dietitian performed TAs assessment through the Common Terminology Criteria for Adverse Event v4.0 (CTCAE) and the Chemotherapy-induced Taste Alteration Scale (CiTAS) questionnaire during chemotherapy and follow-up according to defined time points: at baseline (T0, before starting chemotherapy); at the first follow-up visit, (T1, 2 months after starting chemotherapy); at the final follow-up visit (T2, 1 week after completing chemotherapy); after that, every 3 months up to 12 months. RESULTS: Dysgeusia was reported by 69.8% of patients at T1 and declined subsequently; salty flavor distortion was the most frequently reported TA (51.6% of cases). CiTAS was significantly different between T0 and T2 (p < 0.001). Dysgeusia occurred more frequently in patients reporting nausea, mucositis, diarrhea, and appetite modification. CONCLUSIONS: TAs are common but transient during chemotherapy and occurred frequently with other distressing gastrointestinal side effects. The assessment of these side effects is crucial in managing EBC patients during (neo)adjuvant chemotherapy.

Changes in eating habits and food preferences in breast cancer patients undergoing adjuvant chemotherapy.

Change in eating habits in early breast cancer (EBC) patients during chemotherapy has been poorly studied in the literature. The primary aim of this study was to prospectively evaluate food preferences and weight change in EBC patients before and after adjuvant chemotherapy. From April 2014 to June 2018, 205 EBC patients underwent a dietary assessment according to the following timeline: baseline evaluation (one week before starting chemotherapy, T0); first follow-up (approximately 2-3 months after starting chemotherapy, T1); final follow-up (one week after chemotherapy end, T2). A statistically significant reduction of the following foods was reported after the start of chemotherapy: pasta or rice, bread, breadsticks/crackers, red meat, fat and lean salami, fresh and aged cheese, milk, yogurt, added sugar, soft drinks, alcoholic beverages (wine, beer, and schnapps), and condiments (oil and butter). Conversely, fruit consumption consistently increased. As a result of these changes, a Healthy Eating Index (HEI) specifically developed for this study and suggestive of a balanced diet, significantly increased. Body weight did not increase, despite reduction in physical activity. This prospective study shows that EBC patients tend to adopt "healthier dietary patterns" during adjuvant chemotherapy, leading to a non-change in weight, despite reduction in physical activity.

PONDx: real-life utilization and decision impact of the 21-gene assay on clinical practice in Italy.

Clinicopathological prognostic features have limited value to identify with precision newly diagnosed patients with hormone receptor (HR)-positive, HER2-negative breast cancer (BC), who would benefit from chemotherapy (CT) in addition to adjuvant hormonal therapy (HT). The 21-gene Oncotype DX Breast Recurrence Score® (RS) assay has been demonstrated to predict CT benefit, hence supporting personalized decisions on adjuvant CT. The multicenter, prospective, observational study PONDx investigated the real-life use of RS® results in Italy and its impact on treatment decisions. Physicians' treatment recommendations (HT ± CT) were documented before and after availability of RS results, and changes in recommendations were determined. In the HR+ HER2- early BC population studied (N = 1738), physicians recommended CT + HT in 49% of patients pre-RS. RS-guided treatment decisions resulted in 36% reduction of CT recommendations. PONDx confirms that RS results provide clinically relevant information for CT recommendation in early-stage BC, resulting in a reduction of more than a third of CT use.

The Interaction of Lean Body Mass With Fat Body Mass Is Associated With Vertebral Fracture Prevalence in Women With Early Breast Cancer Undergoing Aromatase Inhibitor Therapy.

Aromatase inhibitors (AIs) induce depletion of estrogen levels, causing bone loss and increased fracture risk in women with breast cancer. High-fat body mass (FBM) emerged as an independent factor associated with the prevalence of morphometric vertebral fractures (VFs) in patients undergoing AIs. We explored the role of lean body mass (LBM) and the interaction of LBM with FBM in predicting the occurrence of VFs in postmenopausal women who were either AI-naïve or AI-treated. A total of 684 consecutive breast cancer patients were enrolled in this cross-sectional study. Each woman underwent a dual-energy X-ray absorptiometry (DXA) scan, measuring bone mineral density (BMD), LBM, and FBM; VFs were assessed using a quantitative morphometric analysis of DXA images. After propensity score matching, the study population was restricted to 480 women, 240 AI-naïve and 240 AI-treated. We used multivariable logistic regression models to explore the associations between baseline characteristics, VF prevalence and the interaction between LBM, FBM and AI therapy. No interaction between LBM and AI therapy on VF prevalence was shown. Conversely, we reported a significant interaction between LBM, FBM and AI therapy (p = .0311). Among AI-treated women having LBM below and FBM above or equal the median value, VF prevalence was numerically higher (15/31; 48.4%) than in other subgroups (VF prevalence: 35.7% in high-LBM and low-FBM group, 23.2% in high-LBM and high-FBM group, and 19.8% in low-LBM and low-FBM group). Among AI-naïve women, the greatest VF proportion was observed in the subgroup with LBM and FBM below median value (25/92; 27.2%). This study suggests a synergism between LBM and FBM in predicting the morphometric VF in women with early breast cancer undergoing AIs. This observation is new and deserves further investigation. The assessment of body composition by DXA might be useful when estimating fracture risk in this population. © 2020 American Society for Bone and Mineral Research © 2020 The Authors.

Efficacy of the DigniCap System in preventing chemotherapy-induced alopecia in breast cancer patients is not related to patient characteristics or side effects of the device.

BACKGROUND: The DigniCap System is an effective scalp cooling device for the prevention of chemotherapy-induced alopecia in early breast cancer patients. AIM: This prospective study was designed to confirm the efficacy and tolerability of the device, to explore potential factors associated with its efficacy and to collect data on patient perceptions and satisfaction. METHODS: Between January 2016 and June 2018, 163 early breast cancer patients eligible for adjuvant chemotherapy were enrolled. Hair loss was assessed using the Dean scale, where a score of 0-2 (hair loss ≤50%) was defined as successful. RESULTS: Hair preservation was successful in 57% of patients in the overall series. The proportion was even higher (81%) in the patient subgroup treated with a paclitaxel and trastuzumab regimen. Side effects (feeling cold, headache, head heaviness, scalp and cervical pain) were mild to moderate and did not correlate with the rate of hair loss. Lifestyle, anthropometric factors and hair characteristics failed to be associated with device efficacy. CONCLUSIONS: The DigniCap System was well tolerated and found to be effective in preventing alopecia in early breast cancer patients. Our study failed to identify factors other than type of chemotherapy regimen associated with hair preservation.

A single-center retrospective safety analysis of cyclin-dependent kinase 4/6 inhibitors concurrent with radiation therapy in metastatic breast cancer patients.

Cyclin dependent kinases 4/6 (CDK4/6) inhibitors gained an essential role in the treatment of metastatic breast cancer. Nevertheless, data regarding their use in combination with radiotherapy are still scarce. We performed a retrospective preliminary analysis of breast cancer patients treated at our Center with palliative radiation therapy and concurrent CDK4/6 inhibitors. Toxicities were measured according to CTCAE 4.0, local response according to RECIST 1.1 or PERCIST 1.0 and pain control using verbal numeric scale. 18 patients (32 treated sites) were identified; 50% received palbociclib, 33.3% ribociclib and 16.7% abemacliclib. Acute non-hematologic toxicity was fair, with the only exception of a patient who developed G3 ileitis. During 3 months following RT, 61.1% of patients developed G 3-4 neutropenia; nevertheless no patient required permanent suspension of treatment. Pain control was complete in 88.2% of patients three months after radiotherapy; 94.4% of patients achieved and maintained local control of disease. Radiotherapy concomitant to CDK4/6 inhibitors is feasible and characterized by a fair toxicity profile, with isolated episodes of high-grade reversible intestinal toxicity. Rate of G 3-4 neutropenia was comparable with that measured for CDK4/6 inhibitors alone. Promising results were reported in terms of pain relief and local control of disease.

Prospective observational study on the impact of the 21-gene assay on treatment decisions and resources optimization in breast cancer patients in Lombardy: The BONDX study.

PURPOSE: Adjuvant treatment decisions in early breast cancer (eBC) have traditionally been driven by risk stratification based on clinical and pathological risk factors. The 21-gene Oncotype DX® assay has been validated as a predictive test for benefit from adjuvant chemotherapy (CT), hence assessing its impact in clinical decisions is of high interest. The objective of this study was to estimate the rate of adjuvant treatment decision modification impacted by the Recurrence Score® result, and the consequent budget impact. METHODS: The study was a multicentre, prospective, real-life experience in Lombardy (Italy) including consecutive patients with T1-T3, N0-N1a, and ER+/HER2-eBC with clinical-pathologic "intermediate risk" of relapse. The change in treatment recommendations was assessed before and after availability of Recurrence Score result. A budget model evaluated the implications of 21-gene testing in the study population. RESULTS: The overall proportion of CT recommendations was reduced from 24.6% to 15.2% after 21-gene testing, with a major impact in patients initially considered for CT plus hormone therapy (CHT). In these patients, the total budget was reduced, leading to a net saving of -€81,017. The greater the physician propensity to prescribe CHT, the higher the potential savings for the health system from sparing CT in most tested patients. CONCLUSIONS: Our real-life experience suggests that all intermediate-risk ER+/HER2-eBC patients who are initially deemed candidates for CHT should be tested with the 21-gene test. The potential to spare CT in at least half of them offers relevant advantages for patients and national health services.

Efficacy of Eribulin mesylate in older patients with breast cancer: A pooled analysis of clinical trial and real-world data.

PURPOSE: Eribulin mesylate (EM) is a non-taxane microtubule inhibitor approved for use in patients with metastatic breast cancer. With this pooled analysis of retrospective studies, we evaluated the efficacy and toxicity profile of EM in older patients with breast cancer in the real-world setting. METHODS: We performed a systematic database search for studies published up to March 2019 and reporting outcome and adverse events with EM in older patients (≥70 years). Overall survival (OS), progression-free survival (PFS), and overall response rate (ORR) were described and aggregated in a pooled analysis. Main toxicity rates (G1-2 and G3-4) were also described. RESULTS: The analysis included five studies for a total of 301 patients. The median age was 71 to 74 years. Pooled ORR, median PFS and OS were 23.2%, 4.8 and 13.1 months, respectively. The disease control rate was 47%. Grade 3-4 neutropenia was 0 to 49%, G3-4 anemia and thrombocytopenia were rare. The most frequent G3-4 adverse events among non-hematological toxicities were fatigue (5-16.5%) and neurotoxicity (0-10.1%). Dose reduction rate was reported in three studies and carried out in 40% of patients (18.6-84%). CONCLUSIONS: This pooled analysis shows that the median OS in older patients with breast cancer is 13 months, with an ORR of 23%. Control of disease was achieved in about 50% of patients. Dose reduction was relatively frequent and severe toxicities were rare. EM treatment of older patients with breast cancer is feasible and reflects the outcomes for the general population.

Association of Fat Body Mass With Vertebral Fractures in Postmenopausal Women With Early Breast Cancer Undergoing Adjuvant Aromatase Inhibitor Therapy.

Importance: Aromatase inhibitors induce a profound depletion in serum estrogen levels. Postmenopausal obese women receiving aromatase inhibitor therapy may be at increased risk of bone fractures owing to the detrimental association of adiposity with bone quality and the loss of the protective effect of estrogens on bone mineral density. Objective: To determine whether fat body mass (FBM), as measured by dual-energy x-ray absorptiometry, is associated with vertebral fracture prevalence in postmenopausal women undergoing adjuvant aromatase inhibitor therapy for breast cancer. Design, Setting, and Participants: In this single-center, cross-sectional study, 556 postmenopausal women with early-stage breast cancer were consecutively enrolled from October 15, 2013, to June 30, 2018, and stratified according to whether they were aromatase inhibitor-naive or aromatase inhibitor-treated for at least 2 years. The database was locked on December 31, 2018, and data analysis was completed on February 28, 2019. Eligible patients in both groups had normal renal function, no metabolic diseases, and no previous or current treatment with antiosteoporotic drugs or glucocorticoids. Previous chemotherapy, but not tamoxifen, was permitted. Data were gathered once, at baseline. Main Outcomes and Measures: Vertebral fracture prevalence associated with FBM in aromatase inhibitor-naive and aromatase inhibitor-treated patients. Results: Of the 556 women enrolled, the mean age was 63.0 years (95% CI, 62.2-63.8 years). The 195 aromatase inhibitor-treated patients were older than the 361 aromatase inhibitor-naive patients (mean age, 66.1 vs 61.3 years; P < .001), had a higher body mass index (mean, 26.4 vs 25.3; P = .009), were less likely to engage in physical activity (65.3% vs 73.7%; P = .03), and were less likely to consume alcoholic beverages (68.4% vs 80.9%; P = .001). Among the aromatase inhibitor-naive patients, the vertebral fracture prevalence was higher in the subgroup with FBM below the median value than in those with high FBM, but the difference was not statistically significant (19.2% vs 13.3%; P = .13). Conversely, the proportion of vertebral fractures in the aromatase inhibitor-treated group was 20.0% in patients with low FBM vs 33.3% in patients with high FBM (P = .04). An opposite trend in the association of FBM with vertebral fracture prevalence according to aromatase inhibitor group was shown by multivariable analysis in the propensity score-matched sample: odds ratio, 0.38 (95% CI, 0.12-1.19) and 1.94 (95% CI, 0.67-5.64) in the aromatase inhibitor-naive and aromatase inhibitor-treated groups, respectively (odds ratio for the interaction, 5.77 [95% CI, 1.08-30.81]; P for interaction term = .03). Conclusions and Relevance: Fat body mass may be associated with fragility-related fractures in patients with breast cancer who undergo aromatase inhibitor therapy. If these data are confirmed, obesity could be included in the algorithm for assessing fracture risk and selecting patients to receive bone resorption inhibitors.

Eribulin in Heavily Pretreated Metastatic Breast Cancer Patients in the Real World: A Retrospective Study.

OBJECTIVES: The aim of this study was to investigate efficacy and safety of eribulin in heavily pretreated patients with advanced breast cancer (BC) in a real-life setting. METHODS: This retrospective monocentric study included patients with HER-2-negative metastatic BC, pretreated with anthracyclines and taxanes, who were referred to the Oncology Department of Spedali Civili of Brescia from May 2012 to April 2017. Patients received the same dose of eribulin as that used in the EMBRACE trial: 1.4 mg/m2 on days 1 and 8 every 21 days. RESULTS: In a total of 53 patients, 32% obtained a partial response, 11% a stable disease, and 43% a clinical benefit (CB). After a median follow-up of 36 months, median progression-free survival (PFS) was 4.7 months and median overall survival (OS) 13.53 months. Median PFS was significantly longer in patients who reported a CB compared to those with no CB, while survival outcomes (PFS and OS) were better in patients who received > 6 cycles of eribulin. Eribulin showed a good tolerability profile with acceptable toxicities, similar to those reported in EMBRACE. CONCLUSIONS: Our experience in a real-world setting confirms the activity, efficacy, and good tolerability profile of eribulin in heavily pretreated BC patients.

The involvement of early stage breast cancer patients during oncology consultations in Italy: a multi-centred, randomized controlled trial of a question prompt sheet versus question listing.

OBJECTIVES: To investigate, prior to an oncology consultation, the use of a pre-prepared list of evidence based questions, Question Prompt Sheet (QPS), compared with a Question List (QL), a patient self-generated list of questions. DESIGN: Multi-centred, randomised controlled trial. SETTING: Secondary-care patients attending three outpatient oncology clinics in Northern Italy. PARTICIPANTS: 308 women completed the study. Inclusion criteria were an age between 18 and 75 years, a recent diagnosis of early stage, non-metastatic breast cancer, adequate Italian language skills, no previous oncology visits and no evidence of cognitive impairment. INTERVENTION: Patients received the QPS or the QL prior to the consultation, completed it without suggestion or coaching session and delivered back before the visit.The consultations were audio-recorded and analysed for the number and content of questions. Multilevel linear models were used to compare the two groups. OUTCOME MEASURES: The primary outcome was the comparison of questions asked between QPS and QL group. Secondary outcomes included satisfaction about questions asked, satisfaction with decision, and level of anxiety. RESULTS: Patients in the QPS and QL group asked 13 and 16 questions respectively. The difference was not significant (b=1.7, CI -0.3 to 3.6, p=0.10). A mean of 22 questions was selected in the QPS, while a mean of 2 questions was written in the QL. Patients in the QPS group were significantly less satisfied (t=3.60, p<0.01) with questions asked but wanted less additional information (t=2.20, p<0.05). Levels of patient decisional satisfaction were equivalent between groups. Similarly, anxiety levels were equal between groups prior to the consultation and decreased in similar way after the consultation. CONCLUSIONS: Both interventions have similar impact on patients' participation in terms of question asking during the consultation. Future research is needed in order to explore which components of the interventions are really useful and efficacious. TRIAL REGISTRATION: ClinicalTrials.gov NCT01510964.

Morphometric vertebral fractures in breast cancer patients treated with adjuvant aromatase inhibitor therapy: A cross-sectional study.

BACKGROUND: The impact of long-term adjuvant therapy with aromatase inhibitors (AIs) on vertebral fracture (VF) risk is still unclear. OBJECTIVE: In this cross-sectional study, we explored the prevalence and determinants of VFs in breast cancer (BC) patients before and during AI therapy. Each woman underwent a dual-energy X-ray absorptiometry (DXA) to evaluate bone mineral density (BMD) and identify VFs by a quantitative morphometric approach. Blood samples were collected to measure serum hormone and calcium levels. RESULTS: We consecutively included 263 postmenopausal women with hormone receptor-positive early BC. One-hundred-sixty-nine women were AI-naïve, and 94 were AI-treated. AI-treated patients had lower BMD at total hip (p=0.01) and lumbar spine (p=0.03), higher serum vitamin D (p<0.001) and parathyroid hormone (p=0.006) values as compared to AI-naïve patients. The prevalence of VFs was 18.9% in AI-naïve patients, and 31.2% in those assessed during AI therapy (odds ratio 1.90, 95% CI 1.1-3.5, p=0.03). In AI-naïve patients, VFs were associated with older age (p=0.002) and lower BMD values at femoral neck (p=0.04) and total hip (p=0.007), whereas VFs occurred without association with any parameter analyzed in AI-treated patients. In AI-treated group, the prevalence of VFs was not significantly different between patients with osteoporosis and those with normal BMD (36.7% vs. 20.0%; p=0.31). CONCLUSIONS: In women with early BC, AI therapy is associated with high prevalence of radiological VFs, which were shown to be independent of BMD values during the adjuvant treatment. These findings may be clinically relevant since they may lead to a change in management of AI-induced skeletal fragility. Specifically, the results of this study provide a rationale for performing a morphometric evaluation of VFs in all women undergoing treatment with AIs.

Oral toxicity management in head and neck cancer patients treated with chemotherapy and radiation: Xerostomia and trismus (Part 2). Literature review and consensus statement.

Radiotherapy alone or in combination with chemotherapy and/or surgery is a well-known radical treatment for head and neck cancer patients. Nevertheless acute side effects (such as moist desquamation, skin erythema, loss of taste, mucositis etc.) and in particular late toxicities (osteoradionecrosis, xerostomia, trismus, radiation caries etc.) are often debilitating and underestimated. A multidisciplinary group of head and neck cancer specialists from Italy met in Milan with the aim of reaching a consensus on a clinical definition and management of these toxicities. The Delphi Appropriateness method was used for this consensus and external experts evaluated the conclusions. The paper contains 20 clusters of statements about the clinical definition and management of stomatological issues that reached consensus, and offers a review of the literature about these topics. The review was split into two parts: the first part dealt with dental pathologies and osteo-radionecrosis (10 clusters of statements), whereas this second part deals with trismus and xerostomia (10 clusters of statements).

Oral toxicity management in head and neck cancer patients treated with chemotherapy and radiation: Dental pathologies and osteoradionecrosis (Part 1) literature review and consensus statement.

Radiotherapy alone or in combination with chemotherapy and/or surgery is the typical treatment for head and neck cancer patients. Acute side effects (such as oral mucositis, dermatitis, salivary changes, taste alterations, etc.), and late toxicities in particular (such as osteo-radionecrosis, hypo-salivation and xerostomia, trismus, radiation caries etc.), are often debilitating. These effects tend to be underestimated and insufficiently addressed in the medical community. A multidisciplinary group of head and neck cancer specialists met in Milan with the aim of reaching a consensus on clinical definitions and management of these toxicities. The Delphi Appropriateness method was used for developing the consensus, and external experts evaluated the conclusions. This paper contains 10 clusters of statements about the clinical definitions and management of head and neck cancer treatment sequels (dental pathologies and osteo-radionecroses) that reached consensus, and offers a review of the literature about these topics. The review was split into two parts: the first part dealt with dental pathologies and osteo-radionecroses (10 clusters of statements), whereas this second part deals with trismus and xerostomia.

International Expert Consensus on Primary Systemic Therapy in the Management of Early Breast Cancer: Highlights of the Fifth Symposium on Primary Systemic Therapy in the Management of Operable Breast Cancer, Cremona, Italy (2013).

Expert consensus-based recommendations regarding key issues in the use of primary (or neoadjuvant) systemic treatment (PST) in patients with early breast cancer are a valuable resource for practising oncologists. PST remains a valuable therapeutic approach for the assessment of biological antitumor activity and clinical efficacy of new treatments in clinical trials. Neoadjuvant trials provide endpoints, such as pathological complete response (pCR) to treatment, that potentially translate into meaningful improvements in overall survival and disease-free survival. Neoadjuvant trials need fewer patients and are less expensive than adjuvant trial, and the endpoint of pCR is achieved in months, rather than years. For these reasons, the neoadjuvant setting is ideal for testing emerging targeted therapies in early breast cancer. Although pCR is an early clinical endpoint, its role as a surrogate for long-term outcomes is the key issue. New and better predictors of treatment efficacy are needed to improve treatment and outcomes. After PST, accurate management of post-treatment residual disease is mandatory. The surgery of the sentinel lymph-node could be an acceptable option to spare the axillary dissection in case of clinical negativity (N0) of the axilla at the diagnosis and/or after PST. No data exists yet to support the modulation of the extent of locoregional radiation therapy on the basis of the response attained after PST although trials are underway.

Leptomeningeal metastasis from solid tumors: a diagnostic and therapeutic challenge.

Leptomeningeal metastasis (LM) is a severe complication in the natural history of malignancies that occurs in 4-15 % of patients (pts) with solid tumors. Clinical presentation, cerebrospinal fluid cytology (CSF), and gadolinium magnetic resonance imaging (gdMRI) of the brain and spine are the methods routinely used to diagnose LM. Treatment encompasses involved-field radiotherapy of bulky or symptomatic disease sites and chemotherapy; however, no standard therapy has been established yet. We collected and reviewed retrospectively the clinical, pathological, radiological findings as well as the outcomes of 50 consecutive patients with LM from solid tumors to determine whether the diagnostic modalities and therapeutic procedures affected the outcomes. The results of this study confirm the role of gdMRI in the diagnosis of LM in clinical practice and suggest that an aggressive treatment may improve survival in patients with this debilitating and increasingly frequent neurological complication.

Long-lasting successful cerebral response with sorafenib in advanced renal cell carcinoma.

We report the case of a 75-year old woman who received sorafenib (Nexavar), Bayer Pharmaceuticals Corporation, West Haven, CT) for a CNS relapse of clear cell renal cell carcinoma. After four months of sorafenib treatment, a brain magnetic resonance imaging showed 95%-volumetric regression of cerebral metastasis. To the best of our knowledge, this is the first almost complete resolution of brain metastases in renal cell carcinoma treated with sorafenib that has been described.
