RESUMO

Data from 423 human epidermal growth factor receptor 2-negative (HER2-), hormone receptor-positive (HR+) advanced breast cancer (aBC) patients treated with palbociclib and endocrine therapy (ET) were provided by 35 Italian cancer centers and analyzed for treatment outcomes. Overall, 158 patients were treated in first line and 265 in second/later lines. We observed 19 complete responses and 112 partial responses. The overall response rate (ORR) was 31% (95% confidence interval [CI], 26.6-35.4) and clinical benefit was 52.7% (95% CI, 48-57.5). ORR was negatively affected by prior exposure to everolimus/exemestane ( p = 0.002) and favorably influenced by early line-treatment ( p < 0.0001). At 6 months, median progression-free survival was 12 months (95% CI, 8-16) and median overall survival was 24 months (95% CI, 17-30). More favorable outcomes were associated with palbociclib in early lines, no visceral metastases and no prior everolimus/exemestane. The main toxicity reported was neutropenia. Our results provide further support to the use of palbociclib with ET in HER2-, HR+ aBC. Differences in outcomes across patients subsets remain largely unexplained.

RESUMO

OBJECTIVE: Many methods are available today for human papillomavirus (HPV) testing; they differ for technology, targets, and information on the genotypes detected. In this study, we evaluated the performance of the Onclarity HPV assay in detection and follow-up of cervical preneoplastic lesions. MATERIALS AND METHODS: One hundred sixty-seven women referred to the European Institute of Oncology, Milan, for treatment of cervical lesions were enrolled. We investigated the utility of Onclarity extended genotyping HPV test in the management of cervical intraepithelial neoplasia (CIN) 2+ preneoplastic lesion. RESULTS: At baseline, the concordance was 92% (150/163) between Onclarity and Hybrid Capture 2 (HC2) and 93% (142/152) between Onclarity and linear array, respectively. At follow-up, the concordance between Onclarity and HC2 was 80%. Seven women relapsed: 6 had persistence of the same genotypes and 1 patient tested negative not only with Onclarity but also with HC2 for the presence of a low-risk genotype in the sample. CONCLUSIONS: This study showed that the evaluation of the HPV genotype persistence may represent a valid option to monitor patients treated for CIN 2+ lesions, because relapses were detected only in patients with persistence of the same genotype detected at baseline.

RESUMO

BACKGROUND: The Human papillomavirus is the most common sexually transmitted virus worldwide. The objective of this study was to estimate: 1) the prevalence and the incidence of external genital warts (eGW) in a sample of women attending community outpatient clinics and 2) the total number of eGW cases in the Italian female population aged 15-64 years. METHODS: A prospective study was performed for a 12-month period between 2009 and 2010, among a sample of women attending community gynecological outpatient clinics located throughout Italy. Demographic data, for every woman aged 15-64 years, were collected. For women diagnosed with eGW, behavioral and clinical data were recorded. Prevalence of eGW was calculated as the proportion between the number of women with eGW and that of women visiting any of the participating gynecologists; incidence of eGW was calculated as the proportion between the number of women with a new diagnosis of eGW and that of women visiting any of the participating gynecologists. Standardized prevalence by age was used to estimate the number of eGW cases occurring in the Italian female population aged 15-64 years. RESULTS: In 2009-2010, 44 community gynecologists were included in the network. In one-year period, 16,410 women visited any of the participating gynecologists; 63 women were diagnosed with eGW, corresponding to a prevalence of 3.8 cases per 1,000 women per year (95%CI: 2.9-4.9). The incidence of eGW was 3.0 cases per 1,000 women per year (95%CI: 2.2-3.9). Women aged 15-24 years showed both the highest prevalence and incidence. Prevalence and incidence significantly decreased by increasing age group (p <0.001), and were higher in Southern Italy compared to Central-Northern Italy. The estimated number of women with eGW among women aged 15-64 years in Italy, in 2010, was approximately 69,000. CONCLUSIONS: These data show a high prevalence and incidence of eGW among young women in Italy, stress the effectiveness of community clinical networks in investigating STI epidemiology among women from the general population, confirm the relevance of HPV vaccination programs among adolescents, and underscore the need of promoting safe sex, implementing early diagnosis, treatment and prevention of genital warts.

RESUMO

Under the optimistic assumption of high-prophylactic HPV vaccine coverage, a significant reduction of cancer incidence can only be expected after decades. Thus, immune therapeutic strategies are needed for persistently infected individuals who do not benefit from the prophylactic vaccines. However, the therapeutic strategies inducing immunity to the E6 and/or E7 oncoprotein of HPV16 are more effective for curing HPV-expressing tumours in animal models than for treating human cancers. New strategies/technologies have been developed to improve these therapeutic vaccines. Our studies focussed on preparing therapeutic vaccines with low-cost technologies by DNA preparation fused to either plant-virus or plant-toxin genes, such as saporin, and by plant-produced antigens. In particular, plant-derived antigens possess an intrinsic adjuvant activity that makes these preparations especially attractive for future development. Additionally, discrepancy in vaccine effectiveness between animals and humans may be due to non-orthotopic localization of animal models. Orthotopic transplantation leads to tumours giving a more accurate representation of the parent tumour. Since HPV can cause cancer in two main localizations, anogenital and oropharynx area, we developed two orthotopic tumour mouse models in these two sites. Both models are bioluminescent in order to follow up the tumour growth by imaging and are induced by cell injection without the need to intervene surgically. These models were utilized for immunotherapies with genetic or plant-derived therapeutic vaccines. In particular, the head/neck orthotopic model appears to be very promising for studies combining chemo-radio-immune therapy that seems to be very effective in patients.

RESUMO

HPV vaccines currently marketed in Italy (bivalent and quadrivalent against HPV 16-18 and HPV and 6,11,16,18 respectively) are an extraordinary tool for the primary prevention of HPV related diseases, particularly of the cervical cancer. Although the implementation of the organized vaccination programs has already translated (for some endpoint) in confirmation of clinical efficacy, remains excluded a significant proportion of the diseases linked to non-vaccine HPV types. The new nonavalent vaccine (HPV9), of impending commercialization, represents an evolution of the quadrivalent, the composition of which are added five high-risk HPV types (HPV 31,33,45,52,58). The high clinical-immunological efficacy in experimental trials against the new genotypes (> 96% for CIN2 +), and the equivalence immunogenic to the four already present in the previous vaccine, will render the use of HPV9 a tool able to control in an even more effective HPV disease. The potential of the new vaccine is linked to the reduction of the HPV cancer burden by 2-20% according to anatomical site, with major benefits for cervical cancer, vulvo-vaginal, penile and more limited benefits for anal tumours. Moreover, the potential benefits could be also linked to the reduction of incidence of pre-neoplastic lesions arising in the lower-genital tract, especially in the cervix (CIN2-3), so often cause lengthy and expensive diagnostic and therapeutic procedures. In the face of this broad provision of benefit from HPV9 vaccine, we have also to consider all the variables related to its introduction in the vaccination calendars: the market price, the schedule of administration (currently in three doses) and data regarding the cost-effectiveness. The authors recognize the new vaccine (currently registered only in the US) a lot of potential in the prevention of HPV-related diseases.

RESUMO

Early menopause and related vaginal atrophy is a well known side-effect of hormone adjuvant treatment in breast cancer patients, particularly during aromatase-inhibitors therapy. Due to estrogens contra-indication, proper therapy for such symptom remains often an inadequately addressed clinical problem. After an accurate assessment of the risk/benefit ratio, vaginal low-dose estrogen treatment (better with estriol) [corrected] may have a role in controlling vaginal atrophy in selected and informed breast cancer women.

RESUMO

BACKGROUND: Human Papillomavirus (HPV) is a very resistant, ubiquitous virus that can survive in the environment without a host. The decision to analyse HPV-related diseases in males was due to the broad dissemination of the virus, and, above all, by the need to stress the importance of primary and secondary prevention measures (currently available for women exclusively). The objective of the Consensus Conference was to make evidence-based recommendations that were designed to facilitate the adoption of a standard approach in clinical practice in Italy. METHODS: The Sponsoring Panel put a series of questions to the members of the Scientific Committee who prepared a summary of the currently available information, relevant for each question, after the review and grading of the existing scientific literature. The summaries were presented to a Jury, also called multidisciplinary Consensus Panel, who drafted a series of recommendations. RESULTS: The prevalence of HPV in males ranges between 1.3-72.9%;. The prevalence curve in males is much higher than that in females and does not tend to decline with age. Women appear to have a higher probability of acquiring HPV genotypes associated with a high oncogenic risk, whereas in males the probability of acquiring low- or high-risk genotypes is similar. The HPV-related diseases that affect males are anogenital warts and cancers of the penis, anus and oropharynx. The quadrivalent vaccine against HPV has proved to be effective in preventing external genital lesions in males aged 16-26 years in 90.4%; (95%; CI: 69.2-98.1) of cases. It has also proved to be effective in preventing precancerous anal lesions in 77.5%; (95%; CI: 39.6-93.3) of cases in a per-protocol analysis and in 91.7%; (95%; CI: 44.6-99.8) of cases in a post-hoc analysis. Early ecological studies demonstrate reduction of genital warts in vaccinated females and some herd immunity in males when vaccine coverage is high, although males who have sex with males gained no benefit at all. Males with an immunodeficiency disease are at greater risk of developing disease. Infertility seems to be caused by HPV in some cases. Studies demonstrate vaccination to both genders can be more efficacious and social equity matters are to be taken into consideration. CONCLUSIONS: The Jury made Recommendations based on the scientific evidence presented by the Scientific Committee. Accordingly, for prevention purposes and social fairness and equality, as both sexes are affected by the disease, the vaccination of 12-year-old males against HPV should be recommended in order to guaranty protection to everyone. Aspects related to healthcare policy and economic sustainability, are to be discussed by respective public system representatives. More campaigns to raise awareness through all institutional channels are needed, not only regarding anogenital warts, but for HPV-related diseases in general in males in accordance to new scientific evidences.

RESUMO

This paper summarizes the position of the Italian Society of Vulvology on the clinical approach to vulval disease. A thorough history (general medical, gynaecological, and vulval history) is essential for a successful and fruitful vulvological examination. Characteristics of pruritus (itch) and pain, that are the two main vulval symptoms, should be collected and reported with precision, according to duration, temporal course, location, provocation, and intensity. Physical examination must consider both the general condition of the patient and the specific vulval region, that must be examined following a standardized methodology. The physical examination of the vulva is carried out with naked eye and adequate natural or halogen lighting. The subsequent use of instrumental magnification can be considered on particular parts of skin/mucosa, already highlighted with the first inspection. Also, palpation is essential, allowing to appreciate physical features of vulval lesions: consistency, surface, soreness, adherence to underlying plans. Finally, the five-step approach of the International Society for the Study of Vulvo-vaginal Disease about Terminology and Classification of Vulvar Dermatological Disorders (2012) is summarized. A vulval biopsy may be useful in the following situations: when clinical diagnosis is uncertain, lesion not responding to treatment; histologic confirmation for a clinical diagnosis and exclusion or confirmation of a suspected neoplastic intraepithelial or invasive pathology.

RESUMO

The study aimed to assess the clinical utility in identifying CIN2 or worse (CIN2+), of the Pretect HPV-Proofer test for E6/E7 mRNA detection in Hybrid Capture 2 (HC2)-positive patients, who underwent colposcopy. In particular, the study analyzed the mRNA test performance as the third test in a subgroup of HC2+ patients with less severe than high-grade squamous intraepithelial lesions (HSIL-). We analyzed 464 cervico-vaginal samples by liquid-based cytology (LBC) and PreTect HPV-Proofer. Moreover 231 patients also had a biopsy at baseline and 75, with HSIL-, were followed up within 2 years by LBC, colposcopy, and histology when indicated. The highest sensitivity for CIN2+ belonged to the mRNA compared to LBC, at the HSIL+ threshold (72% vs. 58%), whereas the LBC showed the highest specificity and positive predictive value (PPV) (99 and 93% vs. 73 and 39%, respectively). Focusing on the 408 HSIL- patients, the mRNA positivity was significantly more associated with CIN2+ than CIN2- lesions (p < 0.0001). Moreover, among the 75 HSIL- followed up patients, the mRNA displayed high longitudinal Specificity (89%), even if the sensitivity and the PPV were low (50 and 20%, respectively). The present data suggest that the mRNA test may have a diagnostic and a potentially prognostic role in HC2+/HSIL- patients.

RESUMO

BACKGROUND: The dermoscopic patterns of pigmented skin tumors are influenced by the body site. OBJECTIVE: To evaluate the clinical and dermoscopic features associated with pigmented vulvar lesions. METHODS: Retrospective analysis of clinical and dermoscopic images of vulvar lesions. The χ² test was used to test the association between clinical data and histopathological diagnosis. RESULTS: A total of 42 (32.8%) melanocytic and 86 (67.2%) nonmelanocytic vulvar lesions were analyzed. Nevi significantly prevailed in younger women compared with melanomas and melanosis and exhibited most commonly a globular/cobblestone (51.3%) and a mixed (21.6%) pattern. Dermoscopically all melanomas showed a multicomponent pattern. Melanotic macules showed clinical overlapping features with melanoma, but their dermoscopic patterns differed significantly from those observed in melanomas. CONCLUSION: The diagnosis and management of pigmented vulvar lesions should be based on a good clinicodermoscopic correlation. Dermoscopy may be helpful in the differentiation of solitary melanotic macules from early melanoma.

RESUMO

BACKGROUND: Knowledge about the distribution of human papillomavirus (HPV) genotypes in invasive cervical cancer is crucial to guide the introduction of prophylactic vaccines. We aimed to provide novel and comprehensive data about the worldwide genotype distribution in patients with invasive cervical cancer. METHODS: Paraffin-embedded samples of histologically confirmed cases of invasive cervical cancer were collected from 38 countries in Europe, North America, central South America, Africa, Asia, and Oceania. Inclusion criteria were a pathological confirmation of a primary invasive cervical cancer of epithelial origin in the tissue sample selected for analysis of HPV DNA, and information about the year of diagnosis. HPV detection was done by use of PCR with SPF-10 broad-spectrum primers followed by DNA enzyme immunoassay and genotyping with a reverse hybridisation line probe assay. Sequence analysis was done to characterise HPV-positive samples with unknown HPV types. Data analyses included algorithms of multiple infections to estimate type-specific relative contributions. FINDINGS: 22,661 paraffin-embedded samples were obtained from 14,249 women. 10,575 cases of invasive cervical cancer were included in the study, and 8977 (85%) of these were positive for HPV DNA. The most common HPV types were 16, 18, 31, 33, 35, 45, 52, and 58 with a combined worldwide relative contribution of 8196 of 8977 (91%, 95% CI 90-92). HPV types 16 and 18 were detected in 6357 of 8977 of cases (71%, 70-72) of invasive cervical cancer. HPV types 16, 18, and 45 were detected in 443 of 470 cases (94%, 92-96) of cervical adenocarcinomas. Unknown HPV types that were identified with sequence analysis were 26, 30, 61, 67, 69, 82, and 91 in 103 (1%) of 8977 cases of invasive cervical cancer. Women with invasive cervical cancers related to HPV types 16, 18, or 45 presented at a younger mean age than did those with other HPV types (50·0 years [49·6-50·4], 48·2 years [47·3-49·2], 46·8 years [46·6-48·1], and 55·5 years [54·9-56·1], respectively). INTERPRETATION: To our knowledge, this study is the largest assessment of HPV genotypes to date. HPV types 16, 18, 31, 33, 35, 45, 52, and 58 should be given priority when the cross-protective effects of current vaccines are assessed, and for formulation of recommendations for the use of second-generation polyvalent HPV vaccines. Our results also suggest that type-specific high-risk HPV-DNA-based screening tests and protocols should focus on HPV types 16, 18, and 45.

RESUMO

Although long-term protection is a key-point in evaluating HPV-vaccine over time, there is currently inadequate information on the duration of HPV vaccine-induced immunity and on the mechanisms related to the activation of immune-memory. Longer-term surveillance in a vaccinated population is needed to identify waning immunity, evaluating any requirements for booster immunizations to assess vaccine efficacy against HPV-diseases. Current prophylactic vaccines have the primary end-points to protect against HPV-16 and 18, the genotypes more associated to cervical cancer worldwide. Nevertheless, data from many countries demonstrate the presence, at significant levels, of HPVs that are not included in the currently available vaccine preparations, indicating that these vaccines could be less effective in a particular area of the world. The development of vaccines covering a larger number of HPVs presents the most complex challenge for the future. Therefore, long term immunization and cross-protection of HPV vaccines will be discussed in light of new approaches for the future.

RESUMO

AIMS: To investigate the clinical role of nm23 expression in identifying both high-risk human papillomavirus (HR-HPV) and high-grade cervical lesions or carcinomas [cervical intraepithelial neoplasia 2(+) (CIN2(+) )], and to compare it with p16 overexpression, as this latter biomarker has already been reported widely in HR-HPV infected cervical lesions. METHODS AND RESULTS: Immunohistochemical evaluation of nm23 and p16 in 143 cervical biopsy specimens including negative, low- and high-grade lesions and squamous carcinomas (SC). HR-HPV testing by Digene hybrid capture 2 (HC2) and polymerase chain reaction (PCR) on the cervico-vaginal samples of the same patients. In detecting CIN2(+) , p16 was significantly more sensitive and specific than nm23 (96.3% versus 81.8% and 66% versus 36.4%, respectively, both P < 0.0001). Concerning HR-HPV detection by HC2, p16 showed a significantly higher specificity than nm23 (82% versus 47%, P <0.0001), although the sensitivities were comparable (71% versus 76%). We found a significantly direct correlation between nm23 and HC2 findings. However, nm23 expression did not correlate with HPV16/18 infection. In contrast, we observed a significant association between p16 overexpression and HPV16/18 genotypes. CONCLUSIONS: We confirm the diagnostic value of p16 overexpression. Moreover, despite in vitro data regarding the interaction with the HPV-E7 protein, nm23 does not appear to be a more useful biomarker than p16 in identifying CIN2(+) or HR-HPV infection.

RESUMO

BACKGROUND: Cervical cancer represents an important global public health problem. It is the 2nd most common cancer among women worldwide. Human papillomavirus (HPV) infection is now well-established as a necessary cause of invasive cervical cancer (ICC) development. Only a few studies on HPV prevalence and type-specific distribution in ICC have been conducted in Italy. AIM: To describe the prevalence of HPV and the HPV type-specific distribution in ICC cases identified in Rome, Italy. METHODS: 140 paraffin embedded tissue blocks of primary ICC diagnosed between 2001 and 2006 were identified at the Regina Elena Cancer Institute in Rome (Italy). HPV was detected through amplification of HPV DNA using SPF-10 HPV broad-spectrum primers followed by DEIA and then genotyping by LiPA25 (version 1). RESULTS: 134 cases were considered suitable for HPV DNA detection after histological evaluation; and overall, 90.3% (121/134) HPV prevalence was detected. 111 cases had a single HPV type, 4 cases had an uncharacterized type (HPVX) and 6 cases had multiple HPV infections. The five most common single HPV types among positive cases were: HPV16 (71/121; 58.7%), HPV18 (12/121; 9.9%), HPV31, HPV45 and HPV58 (5/121; 4.1% each). 2 (1.5%) of the single infections and 2 (1.5%) of the multiple infections contained low risk types. Statistically significant differences in the relative contribution of HPV18 were found when comparing squamous cell carcinomas with adenocarcinomas. CONCLUSIONS: HPV16 and HPV18 accounted for almost 70% of all the HPV positive ICC cases. The study provides baseline information for further evaluation on the impact of recently introduced HPV vaccines in Italy.

RESUMO

PURPOSE: Overview of the impact of ano-genital warts in Italy. COMMENTS: In Italy, the HPV infection is not subject to mandatory reporting, the available epidemiological data come from sentinel surveillance of STIs and show a high spread among young people under 25 years and an increase in reports after 2004. Although ano-genital warts are a benign disease, nonetheless they are characterized by a big relational and psycho-sexual impact, due also to high recurrence rates. CONCLUSIONS: It is extremely useful to promote information activities, education in safe sex, early diagnosis and treatment of genital warts. In this context, primary prevention through vaccination represents a valid tool of protection.

RESUMO

E7 protein from cutaneous as well as mucosal HPV types can alter NF-κB activity. Conflicting literature data show a HPV-induced up- or down-regulation of the NF-κB pathway in different cell lines. In a previous study we detected the expression of E7 gene of HPV15 in a subungual tumor of a patient affected by incontinentia pigmenti (IP). IP is a rare X-linked genodermatosis in which the IKKγ gene is altered. From observations in transgenic IKKγ defective mice, it was suggested that IKK-deficient cells may undergo rapid hyper-proliferation and apoptosis/necrosis, leading to increased pro-inflammatory cytokine production in the neighboring IKK-positive cells. The objective of this study was to ascertain if beta HPV 15 can alter apoptosis and NF-κB pathway in normal and IKKγ-deficient keratinocytes. The human immortalized keratinocyte cell line (HaCaT), and human primary keratinocyte (HPK) cells were transduced with a retrovirus expressing E6-E7 proteins of HPV 15 and IKKγ was successful silenced mimicking the HPV15 infection and IP. HPV15 E6-E7 gene expression improved NF-κB activity in human keratinocytes even when IKKγ was silenced by siRNA. In IKKγ silenced keratinocyte cells, TNF-α-induced apoptosis was strongly reduced by the expression of HPV15 E6-E7 genes. Beta HPV15 exerted this anti-apoptotic activity by decreasing pro-apoptotic BAK and cleaved Caspase 3 proteins. In conclusion, we can speculate that presence of persistent infection by beta papillomavirus might influence the biological fate of IP by altering NF-κB activation and apoptosis in IKKγ mutated cells, favoring their survival and possibly the development of tumors in the late stage of disease. Taken together, our data reinforce the importance of host genetic background in the pathogenesis of HPV-associated skin lesions.

RESUMO

In 2007, an Italian cancer research group proposed a specific concerted action aimed at the "analytical and clinica validation of new biomarkers for early diagnosis: Network, resources, methodology, quality control, and data analysis." The proposal united 37 national operative units involved in different biomarker studies and it created a strong coordinative body with the necessary expertise in methodologies, statistical analysis, quality control, and biological resources to perform ad hoc validation studies for new biomarkers of early cancer diagnosis. The action, financed by the Italian Ministry of Health within the Integrated Oncology Program (PIO) coordinated by NCI-Istituto Tumori Bari, started in 2007 and activated 7 projects, each of which focused on disease-specific biomarker studies. Overall, the 37 participating units proposed studies on 50 biomarkers, including analytical and clinical validation procedures. Clusters of units were specifically involved in research of early-detection biomarkers for cancers of the lung, digestive tract, prostate/bladder, and nervous system, as well as female cancers. Furthermore, a cluster involved in biomarkers for bioimaging and infection-related cancers was created. The first investigators' meeting, "Analytical and clinical validation of new biomarkers for early diagnosis," was held on 9 September 2008 in Bari. During this meeting, methodological aspects, scientific programs and preliminary results were presented and discussed.

RESUMO

HPV vaccination has been introduced in clinical practice in recent years and represents the most effective strategy of primary prevention of cervical carcinoma and of female genital preneoplastic conditions. One of the major issues of the subject is represented by vaccination coverage of the target population. Since its introduction, HPV vaccine efficacy has been progressively demonstrated also towards extragenital HPV-correlated conditions and in males too. Moreover, even subjects of older age groups or subjects who already had HPV infections have been demonstrated to received benefits from vaccination, due to improvements of their immunological response. Recently, vaccine efficacy has also been investigated in terms of adjuvant administration after treatments of preneoplastic or benign conditions of the female lower genital tract caused by HPVs; preliminary results indicate an interesting and promising field of application. On this basis, in this article an analysis of the state of the art has been performed, with specific regard to the Italian scenario and with the focus of future perspectives of implementation of the HPV vaccination policy. From the available evidences, the Italian HPV Study Group recommends the extension of systematic HPV vaccination to males too, to adult subjects and also after conservative treatment of genital HPV correlated conditions.

RESUMO

BACKGROUND: The logic behind the outcome of endocrine therapy in breast cancer has long remained poorly understood. The prognostic role of DNA damage and repair biomarkers (DDR) was explored in postmenopausal, hormone-receptor-positive breast cancer patients treated with neoadjuvant hormone therapy (NAHT). METHODS: Data on 55 patients were included. The phosphorylated ataxia-teleangectasia and Rad3-related protein (pATR), phosphorylated ataxia-telangiectasia mutated (ATM) kinase, and phosphorylated H2A Histone Family Member X (γ-H2AX) were evaluated by immunohistochemistry in paired tissues collected at baseline and following NAHT. Biomarkers were considered both singularly and within signatures. Ki-67 percentage change was the primary biomarker endpoint. Classical endpoints were also considered. RESULTS: The most favorable Ki-67 outcome was associated with the γ-H2AX/pATM signature (p = 0.011). In models of Ki-67 reduction, 'luminal B' subtype, higher grade of anaplasia, and the γ-H2AX/pATM signature tested as significant (p < 0.05 for all). Results were confirmed in multivariate analysis. No association was observed with pathologic response. An increase of ∆γ-H2AX in paired breast tissues was associated with longer event-free survival (p = 0.027) and overall survival (p = 0.042). In Cox models, both survival outcomes were solely affected by grade of anaplasia, with less favorable prognosis in the highest grades (p < 0.05 for both). CONCLUSIONS: We report novel evidence of the prognostic role of DDR biomarkers on important patient outcomes in postmenopausal hormone-receptor-positive breast cancer patients treated with NAHT. If confirmed in future and adequately sized trials, our results may help inform therapeutic decisions and clarify underlying biological mechanisms.

RESUMO

We carried out a retrospective observational study of 264 HER2-positive advanced breast cancer (ABC) patients to explore the efficacy of first-line treatment with pertuzumab/trastuzumab/taxane in real-world setting. Survival data were analyzed by Kaplan Meier curves and log rank test. Median follow-up, length of pertuzumab/trastuzumab/taxane treatment and of pertuzumab, trastuzumab maintenance were 21, 4 and 15 months, respectively. The response rate was 77.3%, and the clinical benefit rate 93.6%. Median progression-free survival (mPFS) was 21 months, and median overall survival (mOS) was not reached. When comparing patients by trastuzumab-pretreatment, similar PFS were observed, although a longer OS was reached in trastuzumab-naïve patients (p = 0.02). Brain metastases at baseline and their development in course of therapy were associated with significantly shorter PFS (p = 0.0006) and shorter OS, although at a not fully statistically relevant extent (p = 0.06). The addition of maintenance endocrine therapy (ET) to pertuzumab/trastuzumab maintenance was associated with longer PFS (p = 0.0001), although no significant differences were detected in OS (p = 0.31). Results were confirmed by propensity score analysis (p = 0.003 and p = 0.46, respectively). In multivariate models, longer PFS was related to lower Performance Status (PS) (p = 0.07), metastatic stage at diagnosis (p = 0.006) and single metastatic site (p < 0.0001). An OS advantage was observed with lower PS (p < 0.0001), single metastatic site (p = 0.004), no prior exposure to trastuzumab (p = 0.004) and response to pertuzumab-based treatment (p = 0.003). Our results confirm that trastuzumab/pertuzumab/taxane is the standard of care as first-line treatment of patients with HER2-positive ABC even in the real-world setting. Moreover, the double-maintenance therapy (HER2 block and ET) is strongly recommended when feasible.
