Detection and typization of HPV genotypes in subjects with oral and upper respiratory tract lesions, Milan, Italy.

BACKGROUND: Oral human papillomavirus (HPV) is common among healthy individuals but causes and implications of persistent infections are under evaluation in the pathogenesis of head and neck neoplasms. METHODS: This was a retrospective study evaluating the prevalence of high-risk (HR), probable HR and low-risk (LR) HPV types in patients reporting signs/symptoms of oral and upper respiratory tract lesions. Individuals attending between 2019 and 2022 a University Hospital in Milan, Italy, with risk factors for HPV (unprotected oral sex and/or previous documentation of HPV infection in oral and upper respiratory tract and/or another anatomical site) were included. RESULTS: Fourteen out of 110 (12.7%) individuals tested positive for HPV DNA. The prevalence of HR-HPV and LR-HPV was 3.6% (4/110) and 9.1% (10/110), respectively. No probable/possible HR-HPV was detected. Specifically, 10/110 (9.1%) were diagnosed with 1 LR-HPV genotype, 3/110 (2.7%) were infected with 1 HR-HPV and 1/110 had 3 concomitant HR-HPV types. HPV 16 (2.7%, 3/110) and 6 (4.5%, 5/110) were the most common HR and LR types, respectively. One patient positive for HPV 16, 33 and 35 was diagnosed with cancer at the base of the tongue. Two individuals among those who tested positive for HPV DNA reported previous HPV vaccination. CONCLUSIONS: Our data, in line with observations from previous prevalence studies, support the potential role of HPV in head and neck neoplasms. HPV DNA testing should be performed in patients presenting lesions in oral/respiratory tracts and risk factors for HPV. Improvement in HPV vaccination coverage is warranted.

MYC rearrangements in HIV-associated large B-cell lymphomas: EUROMYC, a European retrospective study.

ABSTRACT: Large B-cell lymphoma (LBCL) carrying MYC rearrangement, alone or together with BCL2 and/or BCL6 translocations, have shown a poor prognosis when treated with rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) in the HIV population. Scanty data are available on the prevalence and prognostic impact of MYC rearrangements in HIV-associated LBCL. We conducted a retrospective study to evaluate the clinical effect of MYC rearrangement in HIV-associated LBCL. We evaluated clinical characteristics, treatment received, and outcome of LBCL in patients with HIV with MYC rearrangement (MYC+) and without MYC rearrangement (MYC-). A total of 155 patients with HIV who had received fluorescence in situ hybridization analysis for MYC were enrolled in 11 European centers: 43 with MYC+ and 112 MYC-. Among patients with MYC, 10 had double-/triple-hit lymphomas, and 33 had isolated MYC rearrangement (single-hit lymphoma). Patients with MYC+ had more frequently advanced stage, >2 extranodal site at presentation, and higher proliferative index. There were no significant differences in overall survival and progression-free survival (PFS) between the 2 groups. However, patients with MYC+ received more frequently intensive chemotherapy (iCT) (44%) than (R)CHOP alone (35%) or infusional treatment (DA-EPOCH-R and R-CDE) (19%). Among patients with MYC+, those who received iCT achieved a better outcome than patients who received nonintensive treatment (complete remission, 84% vs 52%; P = .028; 5-year PFS, 66% vs 36%; P = .021). Our retrospective results suggest that HIV-associated LBCL with MYC+ could be considered for an intensive therapeutic approach whenever possible, whereas (R)CHOP seems to give inferior results in this subset of patients in terms of complete remission and PFS.

Antibody response to three-dose anti-SARS-CoV-2 mRNA-vaccination in treated solid cancer patients.

Solid cancer patients are at higher risk of SARS-CoV-2 infection and severe complications. Moreover, vaccine-induced antibody response is impaired in patients on anticancer treatment. In this retrospective, observational, hypothesis-generating, cohort study, we assessed the antibody response to the third dose of mRNA vaccine in a convenience sample of patients on anticancer treatment, comparing it to that of the primary two-dose cycle. Among 99 patients included, 62.6% were ≥60 years old, 32.3% males, 67.7% with advanced disease. Exactly 40.4% were receiving biological therapy, 16.2% chemotherapy only and 7.1% both treatments. After the third dose, seroconversion rate seems to increase significantly, especially in non-responders to two doses. Heterologous vaccine-type regimen (two-dose mRNA-1273 and subsequent tozinameran or vice versa) results in higher antibody levels. This explorative study suggests that repeated doses of mRNA-vaccines could be associated with a better antibody response in this population. Furthermore, heterologous vaccine-type three-dose vaccination seems more effective in this population. Since this is a hypothesis-generating study, adequately statistically powered studies should validate these results.

Position paper of the Italian association of medical oncology on health disparities among transgender and gender-diverse people: the Assisi recommendations.

Transgender and gender-diverse individuals experience substantial health disparities across the cancer care continuum. Despite well recognized unique healthcare needs, there are barriers in accessing cancer prevention and treatment services, influenced by disadvantages in key social-economic determinants of health which result in worse clinical outcomes, as compared to the general population. The Italian Association of Medical Oncology (AIOM) acknowledges the critical relevance of this issue. The "Assisi Recommendations" here summarize the outcomes of the "AIOM Oncology Ethics Day" dedicated to gender differences in oncology and cancer care of transgender and gender-diverse people. The recommendations generated during a 2-day multidisciplinary discussion address the various aspects of cancer care experience of transgender and gender-diverse people. The promotion of research in this field, through the generation of new evidence and the collection of prospective data, has been identified as a priority action to mitigate these disparities. By acknowledging the challenges of cancer care in transgender and gender-diverse people and recognizing the need for dedicated policy and clinical recommendations, AIOM demonstrates its commitment to improving the health and well-being of all patients with cancer, regardless of their gender identity or any other personal or social circumstances, as part of health-for-all societal vision.

Clinical efficacy of the first two doses of anti-SARS-CoV-2 mRNA vaccines in solid cancer patients.

INTRODUCTION: Cancer patients are frail individuals, thus the prevention of SARS-CoV-2 infection is essential. To date, vaccination is the most effective tool to prevent COVID-19. In a previous study, we evaluated the immunogenicity of two doses of mRNA-based vaccines (BNT162b2 or mRNA-1273) in solid cancer patients. We found that seroconversion rate in cancer patients without a previous exposure to SARS-CoV-2 was lower than in healthy controls (66.7% vs. 95%, p = 0.0020). The present study aimed to evaluate the clinical efficacy of the vaccination in the same population. METHODS: This is a single-institution, prospective observational study. Data were collected through a predefined questionnaire through phone call in the period between the second and third vaccine dose. The primary objective was to describe the clinical efficacy of the vaccination, defined as the percentage of vaccinated subjects who did not develop symptomatic COVID-19 within 6 months after the second dose. The secondary objective was to describe the clinical features of patients who developed COVID-19. RESULTS: From January to June 2021, 195 cancer patients were enrolled. Considering that 7 (3.59%) patients tested positive for SARS-CoV-2 and 5 developed symptomatic disease, the clinical efficacy of the vaccination was 97.4%. COVID-19 disease in most patients was mild and managed at home; only one hospitalization was recorded and no patient required hospitalization in the intensive care unit. DISCUSSION: Our study suggests that increasing vaccination coverage, including booster doses, could improve the prevention of infection, hospitalization, serious illness, and death in the frail population of cancer patients.

Host-Related Factors in the Interplay among Inflammation, Immunity and Dormancy in Breast Cancer Recurrence and Prognosis: An Overview for Clinicians.

A significant proportion of patients treated for early breast cancer develop medium-term and late distant recurrence. The delayed manifestation of metastatic disease is defined as "dormancy". This model describes the aspects of the clinical latency of isolated metastatic cancer cells. Dormancy is regulated by extremely complex interactions between disseminated cancer cells and the microenvironment where they reside, the latter in turn influenced directly by the host. Among these entangled mechanisms, inflammation and immunity may play leading roles. This review is divided into two parts: the first describes the biological underpinnings of cancer dormancy and the role of the immune response, in particular, for breast cancer; the second provides an overview of the host-related factors that may influence systemic inflammation and immune response, subsequently impacting the dynamics of breast cancer dormancy. The aim of this review is to provide physicians and medical oncologists a useful tool to understand the clinical implications of this relevant topic.

Immunogenicity of two doses of BNT162b2 and mRNA-1273 vaccines for solid cancer patients on treatment with or without a previous SARS-CoV-2 infection.

Previous studies on the immunogenicity of SARS-CoV-2 mRNA vaccines showed a reduced seroconversion in cancer patients. The aim of our study is to evaluate the immunogenicity of two doses of mRNA vaccines in solid cancer patients with or without a previous exposure to the virus. This is a single-institution, prospective, nonrandomized study. Patients in active treatment and a control cohort of healthy people received two doses of BNT162b2 (Comirnaty, BioNTech/Pfizer, The United States) or mRNA-1273 (Spikevax, Moderna). Vaccine was administered before starting anticancer therapy or on the first day of the treatment cycle. SARS-CoV-2 antibody levels against S1, RBD (to evaluate vaccine response) and N proteins (to evaluate previous infection) were measured in plasma before the first dose and 30 days after the second one. From January to June 2021, 195 consecutive cancer patients and 20 healthy controls were enrolled. Thirty-one cancer patients had a previous exposure to SARS-CoV-2. Cancer patients previously exposed to the virus had significantly higher median levels of anti-S1 and anti-RBD IgG, compared to healthy controls (P = .0349) and to cancer patients without a previous infection (P < .001). Vaccine type (anti-S1: P < .0001; anti-RBD: P = .0045), comorbidities (anti-S1: P = .0274; anti-RBD: P = .0048) and the use of G-CSF (anti-S1: P = .0151) negatively affected the antibody response. Conversely, previous exposure to SARS-CoV-2 significantly enhanced the response to vaccination (anti-S1: P < .0001; anti-RBD: P = .0026). Vaccine immunogenicity in cancer patients with a previous exposure to SARS-CoV-2 seems comparable to that of healthy subjects. On the other hand, clinical variables of immune frailty negatively affect humoral immune response to vaccination.

The emotional impact of the COVID-19 outbreak on cancer outpatients and their caregivers: results of a survey conducted in the midst of the Italian pandemic.

INTRODUCTION: The study investigates the emotional discomfort of cancer patients and their caregivers, who need to access the oncology day hospital to receive treatment during the COVID-19 pandemic in Italy. METHODS: This is a single-institution, prospective, cross-sectional study. From May to June 2020, the points of view of both patients and caregivers were compared through 2 different multiple-choice questionnaires, enquiring demographic characteristics, changes in emotional status, interpersonal relationships with health professionals (HCPs) and self-perception of treatment outcomes. RESULTS: Six hundred twenty-five patients and 254 caregivers were enrolled. Females were prevalent and patients were generally older than caregivers. Forty percent of patients and 25.6% of caregivers thought they were at a greater risk of contagion because lived together with a cancer patient or accessed the hospital. Both patients (86.3%) and caregivers (85.4%) considered containment measures a valid support to avoid the spread of infection. People with a lower education level were less worried about being infected with SARS-COV-2. Waiting and performing visits/treatments without caregivers had no impact on the emotional status of patients (64.4%), but generated in caregivers greater anxiety (58.8%) and fear (19.8%) of not properly managing patients at home. The majority of patients (54%) and caregivers (39.4%) thought the pandemic does not influence treatment outcomes. The relationship with HCPs was not negatively impacted for majority of patients and caregivers. CONCLUSIONS: Starting from these data, we can better understand the current psychological distress of patients and their families in order to develop potential strategies to support them in this strenuous period of crisis.

Pegylated liposomal doxorubicin as first line treatment in aids-related Kaposi's sarcoma: a real-life study.

Despite the introduction of effective combination antiretroviral therapy (cART) AIDS-related Kaposi Sarcoma (AIDS-KS) remains the most common malignancy in HIV positive patients. In advanced stage or progressive forms, chemotherapy (CT) in combination with cART is the treatment of choice. The aim of the study is to evaluate efficacy and tolerability of Pegylated Liposomal Doxorubicin (PLD) as first line CT in AIDS-KS. In this single institution retrospective study PLD (20 mg/m2 IV every 2 weeks for 6 or 12 cycles) in combination with cART was administered in poor risk and some cases of good prognosis or limited cutaneous disease. Response rate and adverse events to treatment was evaluated. We enrolled 33 patients with AIDS-KS: median age 44ys, male 90.9%, Caucasian 72.7%, cART-naïve (simultaneous diagnosis of HIV infection and KS) 84.4%, median lymphocyte CD4+ count 134cells, median HIV viral load 4.9 log10 copies/ml. 32 patients were assigned to a Poor Risk KS stage. Grade 3-4 toxicity was reported in 9 patients. No cardiovascular events or severe sepsis were described. Complete response was reported in 25 of 31 patients evaluable for efficacy. After a median follow-up of 52 months the 3-years PFS was 68.6%. PLD associated with cART is an effective, feasible and well tolerated first-line CT in advanced AIDS-KS.

Single nucleotide polymorphisms to predict taxanes toxicities and effectiveness in cancer patients.

Taxanes are used in the treatment of several solid tumours. Adverse events (AEs) might be influenced by single nucleotide polymorphisms (SNPs) in genes encoding proteins responsible for pharmacokinetic and pharmacodynamic. In this prospective, monocentric, observational study we explored the effect of SNPs in the main genes involved in taxanes metabolism and transport, on toxicity and efficacy in 125 patients (pts) treated with paclitaxel, nab-paclitaxel, or docetaxel for neoplasms. There was no statistically significant association between the investigated SNPs and AEs. The heterozygous genotype of CYP3A4*22 showed a trend of association with skin reactions in pts treated with paclitaxel and nab-paclitaxel (RR = 6.92; 95% CI 0.47, 99.8; p = 0.0766). CYP2C8*3/*4 variant carriers showed a trend of association with overall AEs in pts treated with paclitaxel and nab-paclitaxel (RR = 1.28; 95% CI 0.96, 1.67; p = 0.0898). No statistically significant relationship with treatment efficacy was found. ABCB1 3435TT showed a trend of association with a higher treatment response (RR = 0.22; 95% CI 0.03, 1.51; p = 0.0876). Despite the population was heterogeneous, CYP3A4*22 and CYP2C8 SNPs may influence paclitaxel and nab-paclitaxel toxicity and ABCB1 c.3435 may affect taxanes effectiveness, even if any statistically significant was found.

A proposal of a "ready to use" COVID-19 control strategy in an Oncology ward: Utopia or reality?

The Coronavirus Disease-2019 (COVID-19) pandemic is spreading in Italy and Lombardy is one of the most affected region. Cancer patients are higher risk of complication from COVID-19 complications; therefore they should be protected from contagion while still ensuring access to cancer care. The aim of this article is to suggest a strategy to reorganize hospital spaces and Healthcare Professionals (HCPs) staff in order to avoid COVID-19 nosocomial infection in an Oncology ward. SARS-CoV-2 is primarily transmitted through respiratory droplets and by contact. We speculated that precautions against droplet and contact transmission should be the proper way to preserve ward from COVID-19. The essence of our protocol involves: triage outside of the ward, identification of risk zones, traffic control, surveillance of all the involved subjects. Whoever attends the ward must follow the general risk prevention and mitigation measures. The application of this practical strategy can contribute to breaking the cycle of community-hospital-community transmission.

ABCB1 c.3435C>T polymorphism is associated with platinum toxicity: a preliminary study.

BACKGROUND: Platinum-based doublets are the standard chemotherapy for lung cancer. The identification of markers associated with drug toxicity may improve the success of the treatment. Single nucleotide polymorphisms (SNPs) mapping into the genes involved in platinum transport or detoxification may explain the occurrence of toxicities. In this study, we evaluated the role of three SNPs in predicting the onset of adverse events for lung cancer patients receiving cisplatin or carboplatin in adjuvant, neo-adjuvant and metastatic settings. METHODS: Eighty-two patients affected by non-small-cell and small-cell lung cancer treated with cisplatin- or carboplatin-based chemotherapy (stage II-IV) were enrolled. Before genetic analysis, patients signed a written informed consent. DNA was extracted from peripheral blood samples and genotypes were determined by real-time PCR. We selected and analyzed three SNPs: ABCB1 c.3435C>T/rs1045642, ABCC2 -24C>T/rs717620 and GSTP1 c.313A>G/rs1695. Patient characteristics and genotypes were correlated with hematological, gastrointestinal and renal toxicity as recorded by Common Terminology Criteria for Adverse Event (CTCAE) v4.03. No neurological toxicity was observed in our patients. RESULTS: Variant alleles were present in 53% of patients for ABCB1 c.3435C >T, 18.3% for ABCC2 -24C> T, and 34.8% for GSTP1 c.313A>G. Heterozygous CT at ABCB1 c.3435 was associated to a lower risk of hematological toxicity compared to homozygous CC (OR = 0.20; 95% CI 0.05, 0.69; p = 0.01). Similar results were observed by genetic dominant model (CT + TT vs CC) and hematological toxicity (OR = 0.26; 95% CI 0.09, 0.79; p = 0.02). No other significant associations were found between toxicity and SNPs. Multivariate analysis confirmed an independent value for the ABCB1 c.3435 C >T polymorphism. CONCLUSIONS: The present study reveals that ABCB1 c.3435C>T polymorphism influences platinum toxicity. The T allele seems to exert a protective effect on the development of toxicities. Further studies, such as epigenetic regulation ones, are needed to validate and shed more light on this association.

A targeted approach to genetic counseling in breast cancer patients: the experience of an Italian local project.

AIMS AND BACKGROUND: Patients with hereditary breast cancer (BC) may benefit from genetic counseling and testing for detection of causative mutations, definition of therapeutic and preventive strategies, and identification of at-risk relatives. Italy has few oncogenetic centers and genetic evaluation of all patients with BC is not feasible. Moreover, lack of uniformity in the selection of patients generates inappropriate referral to the geneticist. We designed a model that may represent a reproducible way to select patients at risk for hereditary BC, with the aims of rationalizing access to genetic centers and improving clinical management and surveillance. METHODS: The genetic unit of a Cancer Center and the Departments of Oncology from 2 public Hospitals in Milan were involved in the project. After training sessions at the genetic unit, operators from the 2 hospitals evaluated all patients with BC attending a first oncologic visit, through a specific interview. Patients considered at risk of hereditary BC attended counseling at the genetic unit. RESULTS: Of 419 patients, 61 (14.5%) were eligible for genetic counseling after the interview. Of these, 46 (10.9%) strictly met testing criteria. Overall, 52 (12.4%) patients underwent genetic counseling and 47 were tested for BRCA1/BRCA2 mutation. After genetic test results, the available options for treatment/surveillance were discussed by a multidisciplinary team, according to the level of genetic risk. CONCLUSIONS: It is possible to improve the process of referring patients with suspected hereditary BC for genetic risk assessment. The application of clinical screening reduced the genetics unit's workload and enabled optimization of time and resources.
