RESUMO

Breast cancer is a growing global public health concern. Thanks to the recent treatments progress, the survival rate of BC patients has significantly improved (88% of 5-year survival rate) and the number of cancer survivors has also increased. Notwithstanding these brilliant results, many BC patients have long-term side effects as pain, oedema, limited mobility, cancer related fatigue, etc. as a consequence of surgical, radiotherapy and medical treatments. For example, posture appears to be frequently altered after mastectomy, due to the impairment of the mobility of the arm caused by surgical scars. All these aspects negatively affect the health-related Quality of Life (QoL) of BC patients. Recent several randomized clinical trials have shown benefits of regular and appropriate physical activity (PA) during and after BC treatment, particularly in terms of benefits for health, reducing fatigue, improving strength levels, QoL and physical function. In this context, two types of sports have demonstrated their affinity and efficacy as treatment support during and after treatments for BC patients: fencing and rowing. Here we report considerations shared with two sport champions: the fencing Olympic gold medal Daniele Garozzo and the rowing World Champion Giovanni Ficarra, with the aim to find the adapted PA for BC patients.

RESUMO

INTRODUCTION: The present analysis aims to evaluate the consequences of a 2-month interruption of mammographic screening on breast cancer (BC) stage at diagnosis and upfront treatments in a region of Northern Italy highly affected by the severe acute respiratory syndrome-related coronavirus-2 (SARS-CoV-2) virus. METHODS: This retrospective single-institution analysis compared the clinical pathological characteristics of BC diagnosed between May 2020 and July 2020, after a 2-month screening interruption, with BC diagnosed in the same trimester of 2019 when mammographic screening was regularly carried out. RESULTS: The 2-month stop in mammographic screening produced a significant decrease in in situ BC diagnosis (-10.4%) and an increase in node-positive (+11.2%) and stage III BC (+10.3%). A major impact was on the subgroup of patients with BC at high proliferation rates. Among these, the rate of node-positive BC increased by 18.5% and stage III by 11.4%. In the subgroup of patients with low proliferation rates, a 9.3% increase in stage III tumors was observed, although node-positive tumors remained stable. Despite screening interruption, procedures to establish a definitive diagnosis and treatment start were subsequently carried out without delay. CONCLUSION: Our data showed an increase in node-positive and stage III BC after a 2-month stop in BC screening. These findings support recommendations for a quick restoration of BC screening at full capacity, with adequate prioritization strategies to mitigate harm and meet infection prevention requirements.

RESUMO

PURPOSE: The aim was to evaluate the role of tumor-infiltrating lymphocytes (TIL) in predicting molecular response after preoperative endocrine or cytotoxic treatment for HR+/HER2- patients who do not achieve a pathological complete response. METHODS: Stromal (Str) TIL were centrally evaluated on samples from diagnostic core-biopsies of HR+/HER2- patients included in two prospective randomized trials: the LETLOB trial (neoadjuvant endocrine-based treatment) and the GIOB trial (neoadjuvant chemotherapy-based treatment). Pre- and post-treatment Ki67 was centrally assessed. RESULTS: StrTIL were evaluable in 111 cases (n = 73 from the LETLOB trial and n = 38 from the GIOB trial). Median StrTIL was 2%. Patients with high StrTIL (StrTIL ≥10%, n = 28) had more frequently breast cancer of ductal histology (p = 0.02), high grade (p = 0.049), and high Ki67 (p = 0.02). After neoadjuvant endocrine treatment (LETLOB cohort), a significant Ki67 suppression (p < 0.01) from pre- to post-treatment was observed in both the low and high StrTIL groups. High StrTIL patients achieve more frequently a relative Ki67 suppression ≥50% from baseline as compared to low StrTIL patients (55 vs. 35%, p non significant). After neoadjuvant chemotherapy (GIOB cohort), a significant Ki67 suppression was observed only for low StrTIL patients (Wilcoxon p = 0.001) and not in the high StrTIL group (p = 0.612). In this cohort, the rate of patients achieving a relative Ki67 suppression ≥50% from baseline was significantly higher in the low vs high StrTIL group (64% vs 10%, p = 0.003). Geometric mean Ki67 suppression was evaluated in each cohort according to StrTIL: the lowest value (-41%) was observed for high StrTIL cases treated with chemotherapy. CONCLUSIONS: This hypothesis-generating study suggests that in HR+/HER2- breast cancer StrTIL at baseline may influence the achievement of a molecular response after neoadjuvant treatment. Further evaluation in large studies is needed, and interaction with the type of treatment warrants to be explored.

RESUMO

BACKGROUND: The aim of this work was to evaluate the impact of (and relative contribution of) tumor-related and immune-related diversity of HER2-positive disease on the response to neoadjuvant chemotherapy plus anti-HER2 agents. PATIENTS AND METHODS: The CherLOB phase II study randomized 121 HER2-positive breast cancer patients to neoadjuvant chemotherapy plus trastuzumab, lapatinib or both. Tumor samples from diagnostic core biopsy were centralized. Tumor-infiltrating lymphocytes (TILs) were evaluated on H&E slides. Intrinsic subtyping was carried out using the research-based 50-gene prediction analysis of a microarray (PAM50) subtype predictor. Immune-related gene signatures were also evaluated. RESULTS: Continuous Str-TILs and It-TILs were significantly associated with pCR [OR 1.03, 95% CI 1.02-1.05 (P < 0.001) and OR 1.09, 95% CI 1.04-1.15 (P < 0.001) for Str-TILs and It-TILs, respectively]. According to PAM50, the subtype distribution was as follows: HER2-enriched 26.7%, Luminal A 25.6%, Luminal B 16.3%, Basal-like 14% and Normal-like 17.4%. The highest rate of pCR was observed for the HER2-enriched subtype (50%), followed by Basal-like, Luminal B and Luminal A (χ(2) test, P = 0.026). Immune gene signatures significantly associated with pCR in univariate analyses were identified: most of them maintained a significant association with pCR in multivariate analyses corrected for PAM50 subtypes, whereas TILs did not. CONCLUSIONS: In this study, both tumor-related and immune-related features contribute to the modulation of pCR after neoadjuvant chemotherapy plus anti-HER2 agents. Immune signatures rather than TILs added significant prediction of pCR beyond PAM50 intrinsic subtypes.

RESUMO

BACKGROUND: There is a need to develop surrogates for treatment efficacy in the neoadjuvant setting to speed-up drug development and stratify patients according to outcome. Preclinical studies showed that chemotherapy induces an antitumor immune response. In order to develop new surrogates for drug efficacy, we assessed the prognostic value of tumor-infiltrating lymphocytes (TIL) on residual disease after neoadjuvant chemotherapy (NACT) in patients with triple-negative breast cancer (TNBC). PATIENTS AND METHODS: Three hundred four TNBC patients with residual disease after NACT were retrospectively identified in three different hospitals. Hematoxylin and eosin-stained slides from surgical postchemotherapy specimens were evaluated for intratumoral (It-TIL) and stromal (Str-TIL) TIL. Cases were classified as High-TIL if It-TIL and/or Str-TIL >60%. RESULTS: TIL were assessable for 278 cases. Continuous It-TIL and Str-TIL variables were strong prognostic factors in the multivariate model, both for metastasis-free [hazard ratio (HR) 0.86, 95% confidence interval (CI) 0.77-0.96, P = 0.01 and HR 0.85, 95% CI 0.75-0.98, P = 0.02 for Str-TIL and It-TIL, respectively] and overall survival (HR 0.86, 95% CI 0.77-0.97, P = 0.01 and HR 0.86, 95% CI 0.75-0.99, P = 0.03 for Str-TIL and It-TIL, respectively). The 5-year overall survival rate was 91% (95% CI 68% to 97%) for High-TIL patients (n = 27) and 55% (95% CI 48% to 61%) for Low-TIL patients (HR 0.19, 95% CI 0.06-0.61, log-rank P = 0.0017). The major prognostic impact of TIL was seen for patients with large tumor burden following NACT (residual tumor >2 cm and/or node metastasis). In all but one High-TIL case, It-TIL and Str-TIL values were lower on the prechemotherapy sample. CONCLUSIONS: The presence of TIL in residual disease after NACT is associated with better prognosis in TNBC patients. This parameter may represent a new surrogate of drug efficacy to test investigational agents in the neoadjuvant setting and a new prognostic marker to select patients at high risk of relapse.

RESUMO

BACKGROUND: Emerging literature data are showing that a change in human epidermal growth factor receptor (HER2) status adversely affects breast cancer patient's prognosis. The aim of this study was to evaluate the prognostic impact of HER2 loss in patients with HER2-positive disease treated with neoadjuvant therapy with or without anti-HER2 agents. METHODS: One hundred and seven consecutive HER2-positive patients were identified from a prospectively maintained database. The first cohort includes 40 patients treated with chemotherapy (CT) alone. The second cohort includes 67 patients treated with neoadjuvant CT plus anti-HER2 agents (trastuzumab and/or lapatinib). HER2 expression was evaluated by immunihistochemistry or fluorescence in situ hybridization on pretreatment core biopsy and on surgical specimen after therapy. RESULTS: The rates of pathologic complete response (pCR) and breast-conserving surgery were higher in the CT + anti-HER2 cohort. A loss of HER2 expression was observed in 40% of the patients with residual disease after CT alone versus 14.7% of the patients after CT + anti-HER2 agents (P = 0.019). Patients not achieving a pCR have a significant increase in the risk of relapse when compared with those achieving a pCR (hazard ratio [HR] 9.55, P = 0.028). Patients with HER2 loss tended to have a higher risk of relapse as comparing to patients with maintained HER2 positivity (HR 2.41, P = 0.063). CONCLUSION: The pCR is confirmed as a powerful predictor of long-term outcome. The rate of HER2 loss is higher in patients receiving neoadjuvant CT without anti-HER2 agents. HER2 status on residual disease after preoperative therapy can be helpful in selecting patients at different risk of relapse, to be included in prospective trial exploring further adjuvant therapy.

RESUMO

BACKGROUND: Tumor phenotype may change during breast cancer progression. This study evaluates the prognostic impact of receptor discordance between paired primaries and recurrences. PATIENTS AND METHODS: One hundred and thirty-nine patients underwent histological sampling of suspected breast cancer recurrence. All the pathology assessments [ER, PgR and human epidermal growth factor receptor 2 (HER2)] on both primaries and confirmed recurrences were performed at the same laboratory. RESULTS: A breast cancer recurrence was confirmed in 119 cases. Rates of discordance were 13.4%, 39% and 11.8% for ER, PgR and HER2, respectively. Ninety-two patients maintained the same tumor phenotype [i.e. the same hormone receptors (HR) and HER2 status], whereas 27 (22.7%) changed during progression. The loss of HR positivity and the loss of HER2 positivity resulted in a worse post-recurrence survival (P=0.01 and P=0.008, respectively) and overall survival (OS; P=0.06 and P=0.0002, respectively), compared with the corresponding concordant-positive cases. Tumor phenotype discordance was associated with worse post-recurrence and OS (P=0.006 and P=0.002, respectively); those cases who turned into triple-negative experienced the poorest outcome, respect to the concordant group (P=0.001, OS). CONCLUSIONS: We demonstrated for the first time an impact on OS of phenotype discordance between primary breast cancer and relapse. Among discordant cases, receptor loss resulted in the main determinant of poorer outcome.

RESUMO

OBJECTIVES: Human papillomavirus (HPV) in oral carcinoma (OSCC) and potentially malignant disorders (OPMD) is controversial. The primary aim was to calculate pooled risk estimates for the association of HPV with OSCC and OPMD when compared with healthy oral mucosa as controls. We also examined the effects of sampling techniques on HPV detection rates. METHODS: Systematic review was performed using PubMed (January 1966-September 2010) and EMBASE (January 1990-September 2010). Eligible studies included randomized controlled, cohort and cross-sectional studies. Pooled data were analysed by calculating odds ratios, using a random effects model. Risk of bias was based on characteristics of study group, appropriateness of the control group and prospective design. RESULTS: Of the 1121 publications identified, 39 cross-sectional studies met the inclusion criteria. Collectively, 1885 cases and 2248 controls of OSCC and 956 cases and 675 controls of OPMD were available for analysis. Significant association was found between pooled HPV-DNA detection and OSCC (OR = 3.98; 95% CI: 2.62-6.02) and even for HPV16 only (OR = 3.86; 95% CI: 2.16-6.86). HPV was also associated with OPMD (OR = 3.87; 95% CI: 2.87-5.21). In a subgroup analysis of OPMD, HPV was also associated with oral leukoplakia (OR = 4.03; 95% CI: 2.34-6.92), oral lichen planus (OR = 5.12; 95% CI: 2.40-10.93), and epithelial dysplasia (OR = 5.10; 95% CI: 2.03-12.80). CONCLUSIONS: The results suggest a potentially important causal association between HPV and OSCC and OPMD.

RESUMO

Percutaneous core biopsy (CB) has been introduced to increase the ability of accurately diagnosing breast malignancies without the need of resorting to surgery. Compared to conventional automated 14 gauge needle core biopsy (NCB), vacuum-assisted needle core biopsy (VANCB) allows obtaining larger specimens and has recognized advantages particularly when the radiological pattern is represented by microcalcifications. Regardless of technical improvements, a small percentage of percutaneous CBs performed to detect breast lesions are still classified, according to European and UK guidelines, in the borderline B3 category, including a group of heterogeneous lesions with uncertain malignant potential. We aimed to assess the prevalence and positive predictive values (PPV) on surgical excision (SE) of B3 category (overall and by sub-categories) in a large series of non-palpable breast lesions assessed through VANCB, also comparison with published data on CB. Overall, 26,165 consecutive stereotactic VANCB were identified in 22 Italian centres: 3107 (11.9%) were classified as B3, of which 1644 (54.2%) proceeded to SE to establish a definitive histological diagnosis of breast pathology. Due to a high proportion of microcalcifications as main radiological pattern, the overall PPV was 21.2% (range 10.6%-27.3% for different B3 subtypes), somewhat lower than the average value (24.5%) from published studies (range 9.9%-35.1%). Our study, to date the largest series of B3 with definitive histological assessment on SE, suggests that B3 lesions should be referred for SE even if VANCB is more accurate than NCB in the diagnostic process of non-palpable, sonographically invisible breast lesions.

RESUMO

BACKGROUND: Preoperative chemotherapy (PCT) allows for in vivo testing of treatment effects on tumor and its microenvironment. Aim of this analysis was to evaluate the effect of PCT on tumor biomarker expression and to evaluate the prognostic role of treatment-induced variation of these biomarkers (molecular response). METHODS: Two hundred and twenty-one stage II-III breast cancer patients were included. The following parameters were evaluated at baseline and on surgical specimens after PCT: estrogen receptor (ER), progesterone receptor (PgR), human epidermal growth factor receptor 2 (HER2), Ki-67, p53, human epidermal growth factor receptor (EGFR), vascular endothelial growth factor receptor 2 (VEGFR2), and apoptosis. RESULTS: A pathological complete response was observed in 8.8% of the patients. PCT induced a significant reduction in the expression of ER, PgR, Ki-67, and apoptosis. As by multivariable model, Ki-67 > or = 15% and nodal positivity after preoperative chemotherapy (PCT) were significant predictors of worse disease-free survival [hazard ratio (HR) 3.79, P < 0.0001 and HR 2.31, P = 0.037, respectively]. Ki-67 > or = 15% after PCT was also a significant predictor of overall survival (HR 3.75, P = 0.013). On the basis of these two parameters, patients were classified into three groups: (i) low risk (negative nodes and Ki-67 <15%), (ii) intermediate risk (nodal positivity or Ki-67 > or = 15%), and (iii) high risk (nodal positivity and Ki-67 > or = 15%). As compared with the low-risk group, the HRs for recurrence were 3.1 and 9.3 for the intermediate- and high-risk group, respectively (P = 0.0001); the HRs for death were 2.4 and 6.5 for the intermediate- and high-risk group, respectively (P = 0.042). CONCLUSIONS: Ki-67 and nodal status have been used to generate a simple and easily reproducible prognostic model, able to discriminate patients with worse prognosis among the heterogeneous group of women with residual disease after PCT.

RESUMO

OBJECTIVE: Orofacial granulomatosis (OFG) is a rare condition characterized by non-caseating granulomas in the orofacial region. Protease-Activated Receptors (PARs) play a role in inflammatory diseases in diverse human tissues. The aim of the study was to investigate the expression of PAR-1, PAR-2, MMP-2, MMP-9, COX-1, and COX-2 in tissues taken from OFG patients. METHODS: PAR-1, PAR-2, MMP-2, MMP-9, COX-1, and COX-2 expression was evaluated by immunohistochemistry in biopsies taken from oral Crohn's disease (five cases), Melkersson-Rosenthal syndrome (MRS) (six cases), cheilitis granulomatosa (five cases) and normal oral mucosa (five cases). RESULTS: PAR-1 was observed in mononuclear inflammatory cells in edematous/lichenoid lesions, whereas a strong PAR-2 immunostaining was detected in epithelioid histiocytes and giant cells in granulomatous lesions, irrespective of the clinical features (Crohn vs MRS). MMPs and COX-2 were expressed in the inflammatory component of edematous/lichenoid lesions and markedly overexpressed in granulomatous lesions. COX-1 was weakly and variably expressed in both edematous/lichenoid and granulomatous lesions. CONCLUSION: Thus, PAR-1 and PAR-2 expressions were related to the intensity and type of inflammatory response but not to the type of clinical lesion. Simultaneous overexpression of PARs, MMPs and COXs suggests synergism among these proinflammatory receptors and enzymes.

RESUMO

Transthyretin (TTR) amyloidosis is a form of systemic amyloidosis caused by an amyloidogenetic TTR variant. The most common mutant forms of TTR are mainly produced by the liver and therefore orthotopic liver transplantation (OLT) is currently accepted as the only known curative treatment. We describe the clinical and pathological features of a patient with TTR variant (gly53glu) with TTR amyloid infiltration of the leptomeningeal vessels in whom fatal cerebral haemorrhage occurred two months after OLT, soon after severe viral pneumonia.

RESUMO

BACKGROUND/AIM: Osteonecrosis of the jaws is being increasingly reported in patients with bone metastasis from a variety of solid tumours and disseminated multiple myeloma receiving intra-venous bisphosphonates. The signs and symptoms that may occur before the appearance of clinical evident osteonecrosis include changes in the health of periodontal tissues, non-healing mucosal ulcers, loose teeth and unexplained soft-tissue infection. A series of nine periodontally involving patients showing osteonecrosis of the jaws that appeared following the intra-venous use of bisphosphonates is reported. MATERIAL AND METHODS: Nine consecutive patients with osteonecrosis of the jaws were prospectically studied. Patients' past medical histories and the drugs that they had received for their malignant disease were systematically documented. Clinical, histopathological and radiographic features and proposal for treatment modalities of osteonecrosis are also reported. RESULTS: Of the nine patients (six women and three men) observed, all had osteonecrosis in the mandible; two had maxillary involvement as well. All nine patients had a history of extraction of periodontally hopeless teeth preceding the onset of osteonecrosis. In two patients, the lesions also appeared in edentulous areas spontaneously. All the patients had received intra-venous bisphosphonates as treatment for their disseminated haematological neoplasms or metastatic bone disease. The duration of bisphosphonate therapy at presentation ranged from 10 to 70 months (median: 33 months). CONCLUSIONS: Jaw osteonecrosis appears to be associated with the intra-venous use of bisphosphonates. Dental professionals should be aware of this potentially serious complication in periodontal patients receiving long-term treatment with bisphosphonates.

RESUMO

We report the case of a 34-year-old woman with clinical, neuroradiological and intraoperative histological findings, suggesting a low-grade astrocytic tumour. The demyelinating nature of the lesion was established through biopsy only after neurosurgery. The lesion size, in fact, greatly exceeded that of the perivenous demyelination seen in typical multiple sclerosis (MS) and tended to present as a space-occupying mass. This case underlines the importance of considering demyelinating isolated lesions in the differential diagnosis of a brain mass. Since misdiagnosis can result in unwarranted and aggressive therapy, it is critical for the neurologist to be aware of this serious diagnostic pitfall.

RESUMO

Herpes simplex virus-type I (HSV-1) is responsible for both primary and recurrent infections of the oral mucosa. The aim of this case report is to show how HSV-1 may cause periodontal damage such as gingival recession. A 26-year-old male patient presented in a private office for the treatment of gingival recessions. He reported that the recessions had appeared suddenly with marginal inflammation of the gingiva and vesicle formation; within a few hours, the gingival tissue had been completely destroyed. The lesions were accompanied by pain, fever, and regional lymphadenopathy. Two weeks later, the patient returned complaining of a recurrence accompanied by pain and lymphadenopathy. The following day, the patient's condition had worsened and the depth of the recession had increased. A biopsy was taken for histological examination. A free epithelial-connective tissue graft was performed. Histological and direct immunofluorescence examinations confirmed the herpetic origin of the lesion. Eight months after surgery, a new herpetic lesion was detected in correspondence to the gingival margin of the first lower right premolar; therefore, acyclovir was prescribed. After 1 week, the antiviral therapy was completely successful; the gingival lesion disappeared, and no recession of the soft tissue margin was observed. Based on these clinical features, diagnosis of gingival recession induced by HSV-1 must be carried out at an early stage to establish a successful therapy.

RESUMO

BACKGROUND: Acanthosis nigricans (AN) is a rare mucocutaneous condition that can involve the oral tissues. There are 2 clinical forms of AN: benign and malignant. Benign AN is related to systemic diseases such as diabetes and obesity or can be induced by drugs such as systemic corticosteroids, nicotinic acid, estrogens, insulin, and fusidic acid. Malignant AN appears in association with tumors such as lung, ovarian, breast, and gastric carcinoma. METHODS: A rare case of malignant AN that initially manifested in the oral cavity of a 73-year-old patient is reported. RESULTS: A bladder and lung carcinoma were detected following the diagnosis of AN. CONCLUSIONS: The diagnostic importance of oral AN is emphasized because, in our patient, its recognition led to the detection of 2 occult malignant tumors.
