RESUMO

OBJECTIVES: Most research addressing needs and concerns of young patients with breast cancer (≤40 years) is retrospective. The HOHO European protocol is a prospective multicenter cohort study of young women with newly diagnosed breast cancer, about fertility, psychosocial and quality of life concerns. Here we report the baseline data and focus on predictors of fertility concerns. MATERIALS AND METHODS: Patient surveys and medical record review were used. The baseline survey included sociodemographic, medical and treatment data as well as questions on fertility concerns and preservation strategies. Subscales from the CAncer Rehabilitation Evaluation System-Short Form (CARES-SF) were administered to measure specific quality of life aspects. Uni- and multivariable modeling were used to investigate predictors of greater fertility concern. RESULTS: Among 297 eligible respondents, 67% discussed fertility issues before starting therapy, 64% were concerned about becoming infertile after treatment, and 15% decided not to follow prescribed therapies. Fifty-four percent of women wished future children before diagnosis; of these, 71% still desired biologic children afterwards. In multivariable analysis, not having children was the only patient characteristic significantly associated with fertility concerns at diagnosis. Twenty-seven percent used fertility preservation strategies. Women who received chemotherapy reported greater physical (p = 0.021) and sexual difficulties (p = 0.039) than women who did not. Women who were married or had a partner reported less psychosocial problems than single women (p = 0.039). CONCLUSIONS: Young women with newly diagnosed breast cancer have several concerns, including, but not limited to, fertility. The HOHO European study provides valuable information to develop targeted interventions.

RESUMO

Solid tumors are infiltrated by immune cells where macrophages and senescent T cells are highly represented. Within the tumor microenvironment, a cross-talk between the infiltrating cells may occur conditioning the characteristic of the in situ immune response. Our previous work showed that tumors induce senescence of T cells, which are powerful suppressors of lympho-proliferation. In this study, we report that Tumor-Induced Senescent (TIS)-T cells may also modulate monocyte activation. To gain insight into this interaction, CD4+ or CD8+TIS-T or control-T cells were co-incubated with autologous monocytes under inflammatory conditions. After co-culture with CD4+ or CD8+TIS-T cells, CD14+ monocytes/macrophages (Mo/Ma) exhibit a higher expression of CD16+ cells and a reduced expression of CD206. These Mo/Ma produce nitric oxide and reactive oxygen species; however, TIS-T cells do not modify phagocyte capacity of Mo/Ma. TIS-T modulated-Mo/Ma show a higher production of pro-inflammatory cytokines (TNF, IL-1ß and IL-6) and angiogenic factors (MMP-9, VEGF-A and IL-8) and a lower IL-10 and IP-10 secretion than monocytes co-cultured with controls. The mediator(s) present in the supernatant of TIS-T cell/monocyte-macrophage co-cultures promote(s) tubulogenesis and tumor-cell survival. Monocyte-modulation induced by TIS-T cells requires cell-to-cell contact. Although CD4+ shows different behavior from CD8+TIS-T cells, blocking mAbs against T-cell immunoglobulin and mucin protein 3 and CD40 ligand reduce pro-inflammatory cytokines and angiogenic factors production, indicating that these molecules are involved in monocyte/macrophage modulation by TIS-T cells. Our results revealed a novel role for TIS-T cells in human monocyte/macrophage modulation, which may have deleterious consequences for tumor progression. This modulation should be considered to best tailor the immunotherapy against cancer.

RESUMO

Fatigue is a common complaint of patients with cancer or other physical or mental disorders. In cancer patients, the estimated prevalence of fatigue is high (about 70% to 90% in different surveys). However, despite the high prevalence and widely recognized clinical relevance of fatigue, few studies have been performed to evaluate the putative causal factors and therapeutic approaches for this condition. The paucity of studies has been mainly because of the lack of proper instruments to quantify this clinical problem. Moreover, fatigue is multifactorial, which makes evaluation of precise relationships with other medical conditions difficult. In particular, fatigue is considered the cardinal symptom of anemia. The pathogenesis of anemia-related fatigue remains unclear, but some suggest that abnormalities in energy metabolism play a role in inducing fatigue. In cancer patients, this effect may be exacerbated by the increased metabolic needs associated with tumor growth. At the clinical level, the relationship between anemia and fatigue is universally accepted. However, early studies were unable to show a clear association between fatigue and hemoglobin levels. Recently, new insights were afforded by the implementation of innovative survey instruments that assess the effects of fatigue and other (nonfatigue) symptoms of anemia on the patient's well-being and quality of life. The use of these validated instruments has shown a direct effect of hemoglobin levels on fatigue and other quality of life parameters. Thus, amelioration of anemia and fatigue should be considered a primary endpoint of antineoplastic and supportive-care treatment of cancer patients. Accordingly, the search for new simplified methods of assessment of fatigue and other anemia-related symptoms and their treatment outcomes should be strongly encouraged.

RESUMO

The aim of this study was to evaluate the diagnostic accuracy of large core breast biopsy with the use of the perforated compression grid (PCG) in a series of 106 consecutive mammographically detected breast lesions. The PCG consists in a fenestrated paddle that replaces the usual mammographic compressor. Each hole in the grid is marked by letters and numbers in order to obtain the coordinates of the area to biopsy. By analysing the two orthogonal projections, the depth of the lesion in the breast is calculated. With the breast positioned in the PCG, a skin incision is made. After calculations about the depth of needle insertion, the tip of the needle is inserted proximally to the target area. In such a way, taking into consideration the total running of the needle (23 mm), a correct sampling is assured, and multiple needle passes are performed. Sensitivity was of 90.62 and 90.90%, specificity was of 100 and 95.45% and positive predictive value was of 100 and 90.90% by excluding and including suspicious diagnoses, respectively, for each computation. In conclusion, the study indicated that image-guided core biopsy performed by the approach of PCG is a cost-effective, simple and accurate technique for the diagnosis of breast lesions, and it could be proposed as a low-cost alternative where the stereotactic equipment is not available.
