Abstract
Women with breast cancer (BC) and antithyroid peroxidase (TPO) autoantibodies (TPOAb) have a better prognosis than women lacking TPOAb. Sera from women with TPOAb displayed immunoreactivity to BC tissue by immunofluorescence that was not apparent in women without TPOAb. We hypothesize a BC/thyroid shared antigen that provides a target for humoral or cell-mediated immune activity; candidates include the sodium/iodide symporter (expressed in thyroid and BC), cross-reacting epitopes in TPO and lactoperoxidase (LPO) or TPO itself. As the association is with TPOAb, we investigated TPO expression in BC, breast peritumoral tissue (PT), other tissues (tumoral and not) and thyroid as positive control. Transcripts for known and novel TPO isoforms were detected in BC (n = 8) and PT (n = 8) but at approximately 10(4) -fold lower than in thyroid while in non-BC tumors (n = 5) they were at the limit of detection. TPO was expressed also in adipose tissue (n = 17), 10(3) -fold lower than in thyroid. Full length TPO (Mr 105-110 kDa) was detected in Western blots in the majority of examined tissues; preabsorption of the TPO antibody with recombinant TPO (but not LPO) reduced the signal, indicating specificity. The same occurred with some lower molecular weight bands, which could correspond to smaller TPO transcript isoforms, present in all samples. In conclusion, TPO is weakly expressed in BC and other tissues; this could partly explain the high frequency and protective role of TPOAb in BC patients. Further studies will investigate tissue specificity, function and immunogenicity of the novel TPO variants (some BC-specific) identified.

Abstract
BACKGROUND An increased frequency of primary hyperparathyroidism (PHP) has been reported in patients with treated breast cancer (BC). PHP has been found in about 7% of BC patients after surgery and radio-, chemio- or hormonal therapy. AIM To evaluate the frequency of PHP in untreated BC patients. SUBJECTS AND METHODS We evaluated 186 women with BC and 233 women with thyroid cancer (TC, no.=122) or benign thyroid diseases (BTD, no.=111). In all patients, serum calcium, albumin, PTH, and 25-hydroxyvitamin D (25-OH vitD) were measured before any treatment. RESULTS Serum calcium concentrations were significantly higher in BC than in TC and BTD groups (median values 9.5 mg/dl, 9.3 mg/dl and 9.3 mg/dl, respectively) but, according to a logistic regression model, calcium was not significantly different between the 3 groups when age was taken into account. In all patients, serum calcium was in the normal range, indicating that no case of overt PHP was present. Five patients (1 in BC, 2 in TC, and 2 in BDT groups) had serum calcium close to the upper limit of normal range, high PTH and low 25-OH vitD, indicating a possible PHP with hypercalcemia masked by concomitant 25-OH vitD deficiency. CONCLUSIONS In untreated BC group, no patient had overt PHP and 1/186 (0.5%) presented a possible PHP masked by 25-OH vitD deficiency, a PHP frequency much lower than that observed in treated BC patients. These data suggest that the treatments of BC may be responsible for the increased frequency of PHP reported in previous studies.

Abstract
Abstract
Triple negative breast cancers (TNBC) account for 15% of breast cancers. TNBCs carry a high risk of recurrence and deaths, due to the high rate of local and systemic relapse in these patients and no therapeutic options except chemotherapy are currently available. The TNBC pattern of recurrence present a distant recurrence peak at approximately 3 years and then declines rapidly thereafter, whereas in all non-TNBC types the recurrence risk seems to be constant over time. TNBC relapse risk is comparable to that of HER2−positive tumors subtype, in which growth-factors released during the healing process accelerate the early recurrences in HER2−positive patients. Thus, we speculate that also TNBC early relapse may depend on their capability to respond to wound-healing stimulation. To this aim, TNBC were treated with drainages to identify which receptors/pathways can be activated and play a driving role in TNBC progression. A pilot reverse phase protein microarray (RPMA) experiment on MDA-MB-231 TN cells drainage-fluids stimulated revealed a specific activation of PDGFR and VEGFR and their downstream pathways, whereas no significant changes were observed in other receptors, such as EGFR, IRS, Met and ERB3. The type of activated receptors suggested the involvement of endothelial receptors upon drainages stimulation and, indeed TNBC cell lines expressed endothelial molecules, such as CD34, CD31, CD146. Beside the proved role of some of these receptors in cellular proliferation, the TNBC endothelial-like phenotype prompt us to analyzed TNBC cell lines capability to form vascular-like channels when seeded on matrigel. Drainages were able to accelerate the formation of vascular channels in TNBC cell lines and, moreover to consistently increase proliferation of TNBC cells compared to non-TNBC cells. To prove whether receptors found activated by drainages play a key role in TNBC progression, we targeted PDGFR, VEGFR and other receptors possibly involved in angiogenesis and vasculogenic mimicry with sunitinib (targeting PDGFR, VEGFR, FGF and c-kit), anti-bFGF antibody (Ab)(targeting the ligand bFGF) and bevacizumab (targeting the VEGF) in TNBC cells drainage-stimulated in vitro. Sunitinib and anti-bFGF Ab halved the proliferation of TNBC cell lines and reduced of almost 60% the formation of vascular-like channels in TNBC cells, whereas bevacizumab modestly affect proliferation but not vasculogenic properties. Notably, sunitinib and anti-bFGF Ab strongly inhibited MDA-MB-231 and MDA-MB-468 xenografts tumor growth (sunitinib: 80%, and 70% Growth Index (GI), respectively; anti-bFGF Ab 70% and 60% GI, respectively) whereas bevacizumab determined no more than 30% decrease of tumor volume. Unfortunately, all these drugs did not efficiently control the development of lung metastases, that indeed significant increased compared to their control, possibly through induction of hypoxia processes. In conclusion, wound healing promotes TNBC progression by sustaining proliferation and vasculogenesis. The use of sunitinib and anti-bFGF antibody strongly inhibited tumor growth in mice models, but significantly increased lung metastases suggesting a combined use of these drugs with molecules able to interfere with hypoxia pathway.

Abstract
BACKGROUND In patients with breast cancer (BC) a high prevalence of benign thyroid diseases (BTD) has been described, Hashimoto's thyroiditis accounting to a large extent for this association. The aim of this study was to evaluate the prevalence of BC in a large group of patients with BTD. PATIENTS Clinical records of 622 consecutive patients with BTD were examined. BC prevalence in BTD patients was compared with BC frequency in general population living in the same country. RESULTS BC prevalence in patients with BTD (38/622; 6.11%) was significantly higher (p=0.0002) compared to BC frequency in general population (2.07%). When patients were divided according to the age of menopause, in females older than 49 yr BC frequency in BTD was significantly higher than in age-matched population (7.6 vs 3.3%; p=0.006), while in females aged 30-49 yr BC frequency in BTD was higher, but not statistically significantly, than in agematched population (3.7 vs 0.5%; p=0.06). No significant difference in BC prevalence was found when patients were grouped according to the diagnosis of thyroid disorders: Graves' disease, Hashimoto's thyroiditis, nodular goiter associated or not associated with serum thyroid autoantibodies (TAb). No significant difference in BC frequency was observed between TAb+ (26/377; 6.9%) and TAb- (12/245; 4.9%) patients. The distribution of known risk factors for breast malignancies was similar in patients with or without BC. CONCLUSION In patients with BTD the prevalence of BC is significantly higher than the expected, showing the usefulness of screening for breast malignancy of patients with BTD.

Abstract
A high incidence of anti-thyroid antibodies (TAb) has been found in patients with breast cancer (BC). The aim of this study was to evaluate the prognostic value of TAb in a group of 47 women submitted to mastectomy for high malignancy degree BC. All patients were evaluated for thyroid disorders after breast surgery and before any anti-tumoral adjuvant therapy. Five yr after BC diagnosis 31/47 (65.9%) patients were alive (survivors group: SG) and 16/47 (34.1%) were dead (deaths group: DG). The overall prevalence of TAb was 15/47 (31.9%): 14/31 (45.1%) in SG and 1/16 (6.2%) in DG (p=0.008). Five-yr mortality was 15/32 (46.9%) in TAb- and 1/15 (6.7%) in TAb+ patients (p=0.01). Eight out of 47 (17.0%) patients had Hashimoto's thyroiditis and 7 of them (87.5%) were in SG. Estrogen receptor (ER) was measured in 43/47 (91.5%) BC specimens. ER was detected in 19/30 (63.0%) patients in SG and 3/13 (23.1%) in DG (p=0.01). Five-yr mortality was 10/21 (47.6%) in ER- and 3/22 (13.6%) in ER+ patients (p=0.008). Absence of ER expression [odds ratio (OR) 6.54; p=0.006] and absence of TAb (OR 9.37; p=0.03) were related to a higher mortality rate. TAb were detected in 8/21 (38.1%) ER- and in 7/22 (31.8%) ER+ patients; no relation was found between ER expression and TAb positivity (p=ns). Patients with ER+ and TAb+ have a better prognosis and the absence of a significant relationship between these two parameters suggests an independent prognostic role in high malignancy degree BC women.

Abstract
BACKGROUND Previous studies have demonstrated a high prevalence of thyroperoxidase antibodies (TPOAb) and autoimmune hypothyroidism in breast cancer (BC). These studies have been performed in BC patients generally 20-30 days after mastectomy. It is known that stress may have an influence on the immune system and a relation between stressful events and the onset or worsening of autoimmune thyroid disorders has been reported by several authors. The aim of the study was to evaluate the prevalence of autoimmune thyroid disease in patients with nodular breast disease selected for surgery before any treatment. Our hypothesis was that the high prevalence of thyroid autoimmune disorders in BC is independent of stressful events represented by surgery and/or anaesthetic procedures. METHODS Our series included 61 consecutive women aged 52.8 +/- 10.2 yrs (mean age +/- s.d.) with nodular breast disease selected for breast surgery: 36 out of 61 of them (59%) had BC and 25 out of 61 had benign breast disease (BBD). Controls included 100 healthy age-matched women. All patients and control subjects were submitted to clinical, ultrasound thyroid evaluation and serum-free thyroxine (FT4), serum-free tri-iodothyronine (FT3), TSH, TPOAb and thyroglobulin antibodies (TgAb) determination. RESULTS Mean FT3, FT4 and TSH concentration showed no differences between BC patients, BBD patients and controls. The prevalence of TPOAb in BC patients (12/36: 33.33%) was significantly higher than in BBD patients (5/25: 20%) (P < 0.01) and in controls (8/100: 8%) (P < 0.01). Similarly, the prevalence of TgAb in BC patients was 12 out of 36 (33.33%) significantly higher than that detected in BBD patients (4/25: 16%) (P < 0.01) and in controls (12/100: 12%) (P < 0.01). Of the 36 BC patients, 20 showed a diffuse hypoechogenicity of the thyroid gland to ultrasound evaluation, significantly higher than in BBD (7/25: 28%) (P = 0.03). Of the 20 BC patients who showed a hypoechogenic pattern of thyroid gland, 10 (50%) were associated with antithyroid antibodies positivity (TAb). This finding was present in two of seven BBD (28.57%) (P < 0.0001). Only two controls showed focal hypoechogenicity of the thyroid gland. Generally, 24 out of 36 (66.7%) of BC and 9 out of 25 (36%) of BBD (P = 0.02) had signs of thyroid autoimmunity consistent with the hypoechogenic pattern of thyroid gland associated or not with TAb; 2 out of 36 (5.55%) of BC and 1 out of 25 (4%) of BBD patients had autoimmune hypothyroidism and no hypothyroidism was found in controls. CONCLUSIONS The results of this study confirm the strong relation between thyroid autoimmunity and BC. This finding is independent of stressful events represented by surgery or anaesthetic procedures. The present data call attention to the usefulness of screening for autoimmune thyroid disorders in patients with nodular breast disease selected for surgery.

Abstract
An association between thyroid autoimmunity and breast cancer (BC) has been consistently reported, but the cause of this association is still unknown. The role of lymphocytic infiltration (LI) in breast tumorigenesis is controversial and several data suggest that in BC an increase of lymphoid cell infiltrates or a dysfunctional local immune response may be detected very early during tumor development. Chronic autoimmune thyroiditis is characterized by different degrees of LI in thyroid gland and BC cells share some antigenic properties similar to those detected in thyroid tissue, such as sodium iodide symporter (NIS) and peroxidase activity. The aim of this study was to evaluate the frequency and amount of LI in malignant and in normal peritumoral breast tissues, as expression of autoimmune morphological changes, in a group of BC patients with thyroid autoimmunity. We suppose that an increased LI in breast tissues of this group of patients may help explain the association between BC and thyroid autoimmunity. The study group included 26 BC patients with thyroperoxidase antibodies positivity (TPOAb+), 14 of them (53.8%) with Hashimoto's thyroiditis (HT), and 30 BC patients with no evidence of thyroid autoimmune disorders. Malignant and surrounding normal breast tissues were assessed for LI. The amount of LI was scored as very scanty or scanty (LI S) and moderate or marked (LI M), independently by two expert pathologists. LI S was detected in 19/26 (73.1%) BC tissues from patients with TPOAb positivity and LI M in 7 (26.9%). All BC patients with HT had LI S. LI S was detected in 25/30 (83%) and LI M in 5/30 (17%) of BC tissue from patients with no thyroid autoimmunity. The difference in the amount of LI of BC tissues in patient with or without autoimmune thyroid disorders was not significant. The LI was generally absent or very scanty in remote breast tissue in all cases. In conclusion, in breast malignancies the presence of humoral and/or clinical evidence of thyroid autoimmunity is not associated to autoimmune morphological changes of cancer and peritumoral normal tissue. The LI does not seem to have any role in tumorigenesis in patients with BC and thyroid autoimmunity.
