RESUMO

The course of multiple myeloma (MM) is influenced by a variety of factors, including the specificity of the tumour microenvironment (TME). The aim of this review is to provide insight into the interplay of treatment modalities used in the current clinical practice and TME. Bortezomib-based triplets are the standard for MM first-line treatment. Bortezomib is a proteasome inhibitor (PI) which inhibits the nuclear factor kappa B (NF-κB) pathway. However, bortezomib is decreasing the expression of chemokine receptor CXCR4 as well, possibly leading to the escape of extramedullary disease. Immunomodulatory drugs (IMiDs), lenalidomide, and pomalidomide downregulate regulatory T cells (Tregs). Daratumumab, anti-cluster of differentiation 38 (anti-CD38) monoclonal antibody (MoAb), downregulates Tregs CD38+. Bisphosphonates inhibit osteoclasts and angiogenesis. Sustained suppression of bone resorption characterises the activity of MoAb denosumab. The plerixafor, used in the process of stem cell mobilisation and harvesting, block the interaction of chemokine receptors CXCR4-CXCL12, leading to disruption of MM cells' interaction with the TME, and mobilisation into the circulation. The introduction of several T-cell-based immunotherapeutic modalities, such as chimeric-antigen-receptor-transduced T cells (CAR T cells) and bispecific antibodies, represents a new perspective in MM treatment affecting TME immune evasion. The optimal treatment approach to MM patients should be adjusted to all aspects of the individual profile including the TME niche.

RESUMO

End-of-treatment (EoT) PET/CT is used as a guide to omit radiotherapy (RT) patients with primary mediastinal large B-cell lymphoma (PMBCL). We present the mature and extended results of a retrospective study evaluating the prognostic significance of EoT-PET/CT after adequate response to R-CHOP. Among 231 consecutive PMLBCL patients, 182 underwent EoT-PET/CT and were evaluated according to the Deauville 5-point scale (D5PS) criteria. Freedom from progression (FFP) was measured from the time of PET/CT examination. Among 182 patients, 72 (40%) had D5PS score 1 (D5PSS-1), 33 (18%) had 2, 28 (15%) had 3, 29 (16%) had 4, and 20 (11%) had 5. The 5-year FFP was 97, 94, 92, 82, and 44% for D5PSS-1, D5PSS-2, D5PSS-3, D5PSS-4, and D5PSS-5, respectively. Among 105 patients with unequivocally negative PET/CT (D5PSS-1/D5PSS-2), 49 (47%) received RT (median dose 3420 cGy) and 56 (53%) did not with relapses in 0/49 vs. 4/56 patients (2 mediastinum and 2 isolated CNS relapses).The 5-year FFP for those who received RT or not was 100% versus 96%, when isolated CNS relapses were censored (p = 0.159). Among D5PSS-3 patients (27/28 irradiated-median dose 3600 cGy), the 5-year FFP was 92%. The 5-year FFP for D5PSS-4 and D5PSS-5 was 82 and 44%; 44/49 patients received RT (median dose 4000 and 4400 cGy for D5PSS-4 and D5PSS-5). Our study supports the omission of RT in a sizeable fraction of PET/CT-negative patients and definitely discourages salvage chemotherapy and ASCT in patients with PMLBCL who conventionally respond to R-CHOP, solely based on PET/CT positivity in the absence of documented progressive or multifocal disease. The persistence of positive PET/CT with D5PSS < 5 after consolidative RT should not trigger the initiation of further salvage chemotherapy in the absence of conventionally defined PD.

RESUMO

Aim: The purpose of this study is to evaluate the role of MET T1010I and MET rs40239 as potential risk factor and/or prognostic markers in patients with triple-negative breast cancer (TNBC). Methods: 114 samples of DNA from paraffin-embedded breast normal tissues of patients with TNBC and 124 samples of healthy controls were collected and analyzed for MET T1010I and MET rs40239 polymorphisms. Results: MET T1010I CT genotype was associated with increased risk of TNBC in both univariate and multivariate analysis. The status of rs40239 was not associated with a higher risk for TNBC at either the univariate or the multivariate analysis. None of the examined polymorphisms was associated with overall survival at the univariate or multivariate Cox regression analysis (adjusted HR=1.35, 95% CI: 0.31-5.97 for MET T1010I CT/TT vs CC; adjusted HR=1.78, 95% CI: 0.73-4.35 for rs40239 AG/GG vs AA). Conclusion: Our case-control study suggests that MET T1010I seems to be a risk factor for TNBC in the Caucasian Greek population, in contrast with MET rs40239, where no correlation was found.

RESUMO

Background. We aimed to develop and validate a conceptual model of multiple myeloma (MM) that characterizes the attributes affecting disease progression and patient outcomes, and the relationships between them. Methods. Systematic and targeted literature reviews identified disease- and patient-specific attributes of MM that affect disease progression and outcomes. These attributes were validated by a Delphi panel of four international MM experts, and a physician-validated model was constructed. Real-world clinical data from the Czech Registry of Monoclonal Gammopathies (RMG) was used to confirm the relationships between attributes using pairwise correlations and multiple Cox regression analysis. Results. The Delphi panel reached consensus that most cytogenetic abnormalities influenced disease activity, which results in symptoms and complications and affects overall survival (OS). Comorbidities and complications also affect OS. The entire panel agreed that quality of life was influenced by comorbidities, age, complications, and symptoms. Consensus was not reached in some cases, in particular, the influence of del(17p) on complications. The relationships between attributes were confirmed using pairwise analysis of real-world data from the Czech RMG; most of the correlations identified were statistically significant and the strength of the correlations changed with successive relapses. Czech RMG data were also used to confirm significant predictors of OS included in the model, such as age, Eastern Cooperative Oncology Group performance status, and extramedullary disease. Conclusions. This validated conceptual model can be used for economic modeling and clinical decision making. It could also inform the development of disease-based models to explore the impact of disease progression and treatment on outcomes in patients with MM.

RESUMO

BACKGROUND: Tumor-infiltrating lymphocytes (TILs) have been shown to be of prognostic value in several cancer types. In early breast cancer, TILs have a prognostic utility, as well, especially in HER2-positive and triple-negative breast cancer. TILs presence is broadly associated with improved survival; however, there is controversy regarding TILs subpopulations. PATIENTS AND METHODS: Early-stage breast cancer patients treated with anthracycline-based chemotherapy within two randomized trials were included in the study. We evaluated, by qRT-PCR, 826 tumor tissue samples for mRNA expression of CD3, CD8, and FOXP3 for potential prognostic significance in terms of disease-free survival (DFS) and overall survival (OS). RESULTS: After a median follow-up of 133.0 months, 255 patients (30.9%) had died and 314 (38.0%) had disease progression. In the univariate analysis, high CD3 and CD8 mRNA expression was found to be of favorable prognostic value for DFS (P = 0.007 and P = 0.016, respectively). In multivariate analyses, the association of high CD8 mRNA expression with increased DFS was retained (HR = 0.77, 95% CI 0.60-0.998, Wald's P = 0.048), whereas that of high CD3 mRNA expression was of marginal statistical significance (HR = 0.77, 95% CI 0.59-1.01, P = 0.059). Moreover, a significant interaction was observed between HER2 status and CD3 mRNA expression with respect to DFS (interaction P = 0.032). In the HER2-positive subgroup, the hazard ratio associated with high CD3 mRNA expression was of greater magnitude (HR = 0.48, 95% CI 0.30-0.76, P = 0.002) compared with the hazard ratio presented above, for the entire cohort. No significant findings were observed for FOXP3 in terms of DFS, while none of the studied markers were of prognostic value for OS. CONCLUSIONS: High CD3 and CD8 mRNA expression in early-stage breast cancer patients is of prognostic value for decreased risk of relapse and, in the future, could potentially be of importance in deciding the most appropriate therapeutic strategy in light of the recent immune-related treatment developments.

RESUMO

Several studies support an important role of angiogenesis in breast cancer growth and metastasis. The main objectives of the study were to investigate the immunohistochemical expression of vascular endothelial growth factor (VEGF) family ligands (VEGF-A and VEGF-C) and receptors (VEGFR1, VEGFR2 and VEGFR3) in breast cancer and their associations with clinicopathological parameters, cancer subtypes/subgroups and patient outcome. Formalin-fixed paraffin-embedded tumor tissue samples were collected from early-stage breast cancer patients treated with anthracycline-based chemotherapy within a randomized trial. Immunohistochemistry was performed on serial 2.5 µm thick tissue sections from tissue microarray blocks. High VEGF-A, VEGF-C, VEGFR1, VEGFR2 and VEGFR3 protein expression was observed in 11.8% (N = 87), 80.8% (N = 585), 28.1% (N = 202), 64.6% (N = 359) and 71.8% (N = 517) of the cases, respectively. Significant associations were observed among all proteins (all p-values <0.05), with the exception of the one between VEGF-C and VEGFR1 (chi-square test, p = 0.15). Tumors with high VEGF-A protein expression, as compared to tumors with low expression were more frequently ER/PgR-negative (33.3% vs. 20.8%, chi-square test, p = 0.009) and HER2-positive (44.8% vs. 20.6%, p<0.001). In addition, tumors with high VEGFR1 expression, were more frequently HER2-positive (32.8% vs. 19.6%, p<0.001), while tumors with high VEGFR3 expression were more frequently ER/PgR-negative (24.9% vs. 17.0%, p = 0.024) and HER2-positive (26.9% vs. 14.8%, p = 0.001). High VEGF-A and VEGF-C protein expression was associated with increased DFS in the entire cohort (HR = 0.57, 95% CI 0.36-0.92, Wald's p = 0.020 and HR = 0.71, 95% CI 0.52-0.96, p = 0.025, respectively), as well as in specific subtypes/subgroups, such as HER2-positive (VEGF-A, HR = 0.32, 95% CI 0.14-0.74, p = 0.008) and triple-negative (VEGF-C, HR = 0.44, 95% CI 0.21-0.91, p = 0.027) patients. High vs. low VEGFR1 expression was an unfavorable factor for DFS in triple-negative patients (HR = 2.74, 95% CI 1.26-5.98, p = 0.011), whereas the opposite was observed among the ER/PgR-positive patients (HR = 0.69, 95% CI 0.48-0.98, p = 0.041). Regarding OS, high VEGF-C protein expression was associated with increased OS in the entire cohort (HR = 0.64, 95% CI 0.46-0.89, Wald's p = 0.008), as well as in in specific subtypes/subgroups, such as ER/PgR-negative (HR = 0.37, 95% CI 0.20-0.71, p = 0.003) and triple-negative (HR = 0.42, 95% CI 0.19-0.90, p = 0.026) patients. In conclusion, high expression of angiogenesis-related proteins is associated with adverse clinicopathological parameters in early-stage breast cancer patients and may be surrogate markers of biologically distinct subgroups of ER/PgR-negative or triple-negative tumors with superior outcome. Further validation of our findings in independent cohorts is needed.

RESUMO

Numerous treatments are available for relapsed and/or refractory multiple myeloma (MM), with safety profiles varying across drug classes and across agents within the same class. Thus, it is important to understand the toxicities of each antimyeloma agent when making treatment decisions. Neutropenia is commonly associated with lenalidomide and pomalidomide, and may be common with histone deacetylase (HDAC) inhibitors, but is relatively unusual with thalidomide, bortezomib, and carfilzomib. Infection was common in trials of lenalidomide and pomalidomide, and upper respiratory tract infection and pneumonia have been seen with carfilzomib. Cardiac toxicity was observed with thalidomide and may occur with proteasome inhibition. Thromboembolic complications occur with thalidomide and its derivatives, but are less common with bortezomib. Peripheral neuropathy (PN), an important complication of MM, may be exacerbated by bortezomib and thalidomide, and was also observed with lenalidomide. In contrast, PN is rarely observed with carfilzomib and pomalidomide. Renal impairment reduces the clearance of lenalidomide but does not seem to affect substantially the pharmacokinetics of pomalidomide, carfilzomib, or bortezomib. Several therapies have recently been approved, such as the oral proteasome inhibitor ixazomib, the HDAC inhibitor panobinostat, and the monoclonal antibodies elotuzumab and daratumumab. Others are still in clinical development, including the HDAC inhibitors romidepsin and vorinostat, with safety data continuing to emerge. Therapy decisions should consider safety profiles in association with pre-existing comorbidities and toxicities from previous therapeutic regimens. Optimal treatment selection and the management of toxicities will result in fewer patients requiring dose reductions and treatment discontinuations, ultimately leading to improved outcomes.

RESUMO

BACKGROUND: Recognizing resistance or susceptibility to the current standard cisplatin and paclitaxel treatment could improve therapeutic outcomes of metastatic or recurrent cervical cancer. METHODS: Forty-five tissue samples from patients participating in a phase II trial of cisplatin and ifosfamide, with or without paclitaxel were collected for retrograde analysis. Immunohistochemistry and genotyping was performed to test ERCC1, III ß-tubulin, COX-2, CD4, CD8 and ERCC1 (C8092A and N118 N) and MDR1 (C3435T and G2677 T) gene polymorphisms, as possible predictive and prognostic markers. Results were statistically analyzed and correlated with patient characteristics and outcomes. RESULTS: Patients with higher levels of ERCC1 expression had shorter PFS and OS than patients with low ERCC1 expression (mPFS:5.1 vs 10.2 months, p = 0.027; mOS:10.5 vs. 21.4 months, p = 0.006). Patients with TT in the site of ERCC1 N118 N and GT in the site of MDR1 G2677 T polymorphisms had significantly longer PFS (p = 0.006 and p = 0.027 respectively). ERCC1 expression and the ERCC1 N118 N polymorphism remained independent predictors of PFS. Interestingly, high III beta tubulin expression was associated with chemotherapy resistance and fewer responses [5/20 (25%)] compared to lower III ß-tubulin expression [15/23 (65.2%)] (p = 0.008). Finally, ΙΙΙ ß-tubulin levels and chemotherapy regimen were independent predictors of response to treatment. CONCLUSIONS: ERCC1 expression proved to be a significant prognostic factor for survival in our metastatic or recurrent cervical cancer population treated with cisplatin based chemotherapy. ERCC1 N118 N and MDR1 G2677 T polymorphism also proved of prognostic significance for disease progression, while overexpression of III ß-tubulin was positively correlated with chemotherapy resistance.

RESUMO

The International Myeloma Working Group consensus aimed to provide recommendations for the optimal use of 18fluorodeoxyglucose (18F-FDG) PET/CT in patients with multiple myeloma and other plasma cell disorders, including smouldering multiple myeloma and solitary plasmacytoma. 18F-FDG PET/CT can be considered a valuable tool for the work-up of patients with both newly diagnosed and relapsed or refractory multiple myeloma because it assesses bone damage with relatively high sensitivity and specificity, and detects extramedullary sites of proliferating clonal plasma cells while providing important prognostic information. The use of 18F-FDG PET/CT is mandatory to confirm a suspected diagnosis of solitary plasmacytoma, provided that whole-body MRI is unable to be performed, and to distinguish between smouldering and active multiple myeloma, if whole-body X-ray (WBXR) is negative and whole-body MRI is unavailable. Based on the ability of 18F-FDG PET/CT to distinguish between metabolically active and inactive disease, this technique is now the preferred functional imaging modality to evaluate and to monitor the effect of therapy on myeloma-cell metabolism. Changes in FDG avidity can provide an earlier evaluation of response to therapy compared to MRI scans, and can predict outcomes, particularly for patients who are eligible to receive autologous stem-cell transplantation. 18F-FDG PET/CT can be coupled with sensitive bone marrow-based techniques to detect minimal residual disease (MRD) inside and outside the bone marrow, helping to identify those patients who are defined as having imaging MRD negativity.

RESUMO

Pregnancy-associated cancer constitutes an uncommon and difficult to manage clinical situation. It is defined as the cancer diagnosed from the first day of childbearing to 1 year post partum. Coexistence of cancer with pregnancy adds complexity to treatment recommendations, as both the mother and the fetus may be affected. The optimal therapeutic management of pregnant women with cancer diagnosis should take into account, apart from medical factors, a host of other parameters (ethical, psychological, religious, legal, etc). Unfortunately, this situation becomes more complex as more women delay childbearing, and consequently the incidence of cancer during pregnancy is constantly increasing. This manuscript summarises the general principles in managing pregnant patients with cancer and gives detailed instructions in the management of pregnant patients with breast cancer, ovarian cancer, melanoma, lymphoma, lung cancer, soft-tissue sarcoma and cervical cancer. Of note, management of pregnant women with cancer diagnosis should be performed in specialised centres with experience and all cases should be discussed in multidisciplinary meetings composed of multiple specialists (medical oncologists, obstetricians, surgeons, radiologists and paediatricians).

RESUMO

BACKGROUND: We investigated the impact of PIK3CA and TP53 mutations and p53 protein status on the outcome of patients who had been treated with adjuvant anthracycline-taxane chemotherapy within clinical trials in the pre- and post-trastuzumab era. RESULTS: TP53 and PIK3CA mutations were found in 380 (21.5%) and 458 (25.9%) cases, respectively, including 104 (5.9%) co-mutated tumors; p53 immunopositivity was observed in 848 tumors (53.5%). TP53 mutations (p < 0.001) and p53 protein positivity (p = 0.001) were more frequent in HER2-positive and triple negative (TNBC) tumors, while PIK3CA mutations were more frequent in Luminal A/B tumors (p < 0.001). TP53 mutation status and p53 protein expression but not PIK3CA mutation status interacted with trastuzumab treatment for disease-free survival; patients with tumors bearing TP53 mutations or immunopositive for p53 protein fared better when treated with trastuzumab, while among patients treated with trastuzumab those with the above characteristics fared best (interaction p = 0.017 for mutations; p = 0.015 for IHC). Upon multivariate analysis the above interactions remained significant in HER2-positive patients; in the entire cohort, TP53 mutations were unfavorable in patients with Luminal A/B (p = 0.003) and TNBC (p = 0.025); p53 immunopositivity was strongly favorable in patients treated with trastuzumab (p = 0.009). MATERIALS AND METHODS: TP53 and PIK3CA mutation status was examined in 1766 paraffin tumor DNA samples with informative semiconductor sequencing results. Among these, 1585 cases were also informative for p53 protein status assessed by immunohistochemistry (IHC; 10% positivity cut-off). CONCLUSIONS: TP53 mutations confer unfavorable prognosis in patients with Luminal A/B and TNBC tumors, while p53 immunopositivity may predict for trastuzumab benefit in the adjuvant setting.

RESUMO

BACKGROUND: Intensive chemotherapy confers benefit to patients with high-risk early breast cancer (BC). We characterized the feasibility and toxicity profile of anthracycline-containing adjuvant chemotherapy (ACAC) in older women with early BC. PATIENTS AND METHODS: Available data from women who received ACAC for BC in 3 randomized trials were retrieved. We identified women aged >65 years and we examined differences in tolerability and delivery of chemotherapy, toxicity, and treatment outcome. RESULTS: From a total of 2640 patients, we identified 453 patients (17%) as being >65 years old, 89% of whom had tumors that were node-positive, with 77% who were hormone receptor-positive. At least 90% of the planned doses were delivered in 37% of the elderly, compared with 49% in the younger patients (P < .0001). Grade 3 and 4 hematological toxicity was observed in 32% of elderly patients, compared with 21% of the younger (P < .0001). Febrile neutropenia occurred in 4.5% of the elderly patients, as opposed to 2.0% in the younger patients (P < .002). Elderly patients experienced more frequent Grade 3 and 4 fatigue, mucositis, and sensory neuropathy. Relative dose intensities were significantly lower in elderly patients. Treatment discontinuation was not different in the 2 groups. At a median follow-up of 120 months, competing risks analysis showed a significant benefit in disease-free survival for elderly patients. CONCLUSION: Elderly BC patients treated with ACAC derive clinical benefit comparable to that in younger patients, mainly at the cost of increased risk of hematological toxicity. This should be taken into account in decision-making and treatment individualization in high-risk BC patients.

RESUMO

Ovarian cancer is the most lethal gynecologic malignancy; consequently, there is a need for effective therapies. Epothilones are microtubule-stabilizing agents that inhibit cell growth. Currently, patupilone and its four synthetic derivatives ixabepilone, BMS-310705, sagopilone, 20-desmethyl-20-methylsulfanyl epothilone B and epothilone D, as well as its derivative KOS-1584, are under clinical evaluation. This is the first systematic review conducted in accordance with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines that synthesizes all available data emerging from trials and evaluates the efficacy and safety of epothilones in epithelial ovarian, primary fallopian tube, and primary peritoneal cancer. Despite the fact that epothilones have proven active in taxane-resistant settings in preclinical models, it is not yet clear from Phase II/III studies reviewed here that their clinical activity is superior to that of taxanes. Nevertheless, responses to epothilones have been observed in platinum-refractory/resistant ovarian cancer patients. Moreover, despite the shared mechanism of action of epothilones, their clinical profile seems clearly different, with diarrhea being the most common dose-limiting toxicity encountered with patupilone, whereas neutropenia and sensory neuropathy are the most common toxic effects observed with the other epothilones. In any case, randomized trials comparing epothilones with standard treatments seem warranted to define further the role of these agents, whereas biomarker analysis might further optimize patient selection.

RESUMO

Although several studies have shown the efficacy of third-generation aromatase inhibitors (AIs) in women with breast cancer, the role of such molecules remains elusive in male breast cancer patients. It is also unknown whether the addition of gonadotropin-releasing hormone (GnRH) analogues to AIs would be a superior strategy or not. This pooled analysis was conducted in accordance with the PRISMA guidelines. All studies that examined the efficacy of AIs in metastatic male breast cancer were considered eligible. Overall, 15 studies (105 cases) were eligible for this pooled analysis. The mean age of the study sample was 62.8 years. ER status was positive in all eligible cases. AI was given as first line in 61.5 % of cases. GnRH analogue was co-administered with AI in 37.1 % of cases (n = 39). CR, PR, SD and PD were achieved in 5.7, 23.8, 37.2 and 33.3 % of cases, respectively. The median PFS and OS were equal to 10.0 and 39.0 months, respectively. Co-administration of GnRH analogues was associated with more than threefold increase in rates of clinical benefit (OR = 3.37, 95 % CI 1.30-8.73) but did not seem to correlate with better PFS or OS. No statistically significant associations between the examined outcomes and the other parameters were noted. Available data suggest that AIs may potentially play a promising role in the optimal therapeutic strategy for metastatic male breast cancer patients. Especially, co-administration of AI with a GnRH analogue seems to increase the rate of clinical benefit and could be more effective, warranting further consideration.

RESUMO

An ever growing number of medical organizations, societies, working groups and governmental agencies issue algorithms i.e. guidelines, of decision making flowcharts in diagnosis and treatment in a variety of diseases. In the field of evidence-based diagnosis and treatment of breast cancer, a large number of guidelines are available both from medical associations and national health departments. Among the most appreciated and utilized comprehensive guides is the European Society for Medical Oncology (ESMO) Breast Cancer Guidelines and from the other side of the Atlantic the National Comprehensive Cancer Network (NCCN) Guidelines in Breast Cancer. Although there is much concordance between the guidelines from these two organizations, it is intriguing to locate their discrepancies also. The aim of this report is to present a number of different points between ESMO and NCCN in the whole spectrum of breast cancer management, from prevention and diagnosis to treatment and follow up. This systematic review was performed in accordance with the PRISMA guidelines using a predefined search strategy and summarizes in detail, the differences between ESMO and NCCN guidelines regarding genetic risk evaluation and screening, surgery, chemotherapy, endocrine treatment, targeted biological agents, radiotherapy, pregnancy and fertility and follow-up.

RESUMO

BACKGROUND: Elderly patients with advanced non-small cell lung cancer (NSCLC) are thought to receive suboptimal treatment mainly due to concerns for poor compliance and/or excessive toxicity. PATIENTS AND METHODS: Using the age of 70 years as the pre-defined cut-off, we compared elderly patients with advanced NSCLC suitable for first line chemotherapy with their younger counterparts in terms of: i) diagnosis and disease characteristics ii) adherence to treatment schedule, including dose intensity (DI), and relative dose intensity (RDI), iii) toxicity, tolerance, and efficacy outcomes. RESULTS: Among 292 eligible patients, data were available for 245, of whom 107 (43.7%) belonged to the elderly group. This group was more likely to present with co-morbidities, non-smoking current status and diagnosis based on cytology alone. As compared to the non-elderly, elderly patients were more likely to receive single-agent therapy (8.0% vs. 29.2% respectively, p < 0.001) and less likely to receive platinum-based chemotherapy (80.3% vs. 57.9%, p < 0.001). Elderly patients also received docetaxel (24.3% vs. 40.4%), and bevacizumab (7.5% vs. 21.3%) significantly less often and received oral vinorelbine (24.3% vs. 11.8%) more frequently. Non-elderly patients were more likely to receive any of the cytotoxic drugs with RDI > 0.8 (49.6% vs. 33.0%, p = 0.012) and RDI > 0.9 (29.6% vs. 16%, p = 0.015). Substantial toxicity, as well as median overall survival did not differ significantly between the two groups. CONCLUSIONS: Only one third of the elderly patients received at least 80% of the scheduled treatment intensity. Nearly half received diagnosis based on cytology alone, which may deprive them from new, histology-driven, therapeutic approaches.

RESUMO

BACKGROUND: Dose-dense sequential chemotherapy including anthracyclines and taxanes has been established in the adjuvant setting of high-risk operable breast cancer. However, the preferable taxane and optimal schedule of administration in a dose-dense regimen have not been defined yet. METHODS: From July 2005 to November 2008, 1001 patients (990 eligible) were randomized to receive, every 2 weeks, 3 cycles of epirubicin 110 mg/m2 followed by 3 cycles of paclitaxel 200 mg/m2 followed by 3 cycles of intensified CMF (Arm A; 333 patients), or 3 cycles of epirubicin followed by 3 cycles of CMF, as in Arm A, followed 3 weeks later by 9 weekly cycles of docetaxel 35 mg/m2 (Arm B; 331), or 9 weekly cycles of paclitaxel 80 mg/m2 (Arm C; 326). Trastuzumab was administered for one year to HER2-positive patients post-radiation. RESULTS: At a median follow-up of 60.5 months, the 3-year disease-free survival (DFS) rate was 86%, 90% and 88%, for Arms A, B and C, respectively, while the 3-year overall survival (OS) rate was 96% in all arms. No differences were found in DFS or OS between the combined B and C Arms versus Arm A (DFS: HR = 0.81, 95% CI: 0.59-1.11, P = 0.20; OS: HR = 0.84, 95% CI: 0.55-1.30, P = 0.43). Among the 255 patients who received trastuzumab, 189 patients (74%) completed 1 year of treatment uneventfully. In all arms, the most frequently reported severe adverse events were neutropenia (30% vs. 27% vs. 26%) and leucopenia (12% vs. 13% vs. 12%), while febrile neutropenia occurred in fifty-one patients (6% vs. 4% vs. 5%). Patients in Arm A experienced more often severe pain (P = 0.002), neurological complications (P = 0.004) and allergic reactions (P = 0.004), while patients in Arm B suffered more often from severe skin reactions (P = 0.020). CONCLUSIONS: No significant differences in survival between the regimens were found in the present phase III trial. Taxane scheduling influenced the type of severe toxicities. HER2-positive patients demonstrated comparable 3-year DFS and OS rates with those reported in other similar studies.

RESUMO

PURPOSE: The establishment of high dependency units (HDUs) has been an undoubted advance in the management of patients undergoing major oncological procedures. The aim of this study was to examine the impact of various preoperative and perioperative patients' characteristics on the prolonged HDU stay. METHODS: We conducted a retrospective study including all gynecologic oncology patients who underwent surgical management and were admitted postoperatively to our hospitals' HDU from 2006 to 2010. RESULTS: A total of 1,014 patients were transferred to the HDU and divided into two groups according to the length of HDU stay. Group A consisted of 840 (82.8 %) patients who stayed in the HDU for ≤24 h and Group B included 174 (17.2 %) patients who remained in the HDU under close observation for >24 h. Older age was the only preoperative characteristic that remained significantly associated with HDU prolonged stay. In addition, three intraoperative factors such as use of invasive hemodynamic monitoring, bowel resection and estimated blood loss were proved to be independently associated with prolonged HDU stay. CONCLUSION: Certain characteristics could identify those patients who are more likely to benefit most from HDU admission.
