The effect of cellular nuclear function alteration on the pathogenesis of shoulder adhesive capsulitis: an immunohistochemical study on lamin A/C expression.

BACKGROUND: The network of intermediate filament proteins underlying the inner nuclear membrane forms the nuclear lamina. Lamins have been associated with important cellular functions: DNA replication, chromatin organization, differentiation of the cell, apoptosis and in maintenance of nuclear structure. Little is known regarding the etiopathogenesis of adhesive capsulitis (AC); recently, a dysregulating fibrotic response starting from a subpopulation has been described within the fibroblast compartment, which suddenly turns on an activated phenotype. Considering the key role of A-type lamins in the regulation of cellular stability and function, our aim was to compare the lamin A/C expression between patients with AC and healthy controls. MATERIALS AND METHODS: A case-control study was performed between January 2020 and December 2021. Tissue samples excised from the rotator interval were analysed for lamin A/C expression by immunohistochemistry. Patients with AC were arbitrarily distinguished according to the severity of shoulder flexion limitation: ≥ 90° and < 90°. Controls were represented by samples obtained by normal rotator interval excised from patients submitted to shoulder surgery. The intensity of staining was graded, and an H-score was assigned. Statistical analysis was performed (Chi-square analysis; significance was set at alpha = 0.05). RESULTS: We enrolled 26 patients [12 male and 14 female, mean age (SD): 52.3 (6.08)] and 15 controls [6 male and 9 female, mean age (SD): 57.1 (5.3)]. The expression of lamin A/C was found to be significantly lower in the fibroblasts of patients with adhesive capsulitis when compared with controls (intensity of staining: p: 0.005; H-score: 0.034); no differences were found regarding the synoviocytes (p: > 0.05). Considering only patients with AC, lamin A/C intensity staining was found to be significantly higher in samples where acute inflammatory infiltrate was detected (p: 0.004). No significant changes in levels of lamin A/C expression were documented between the mild and severe adhesive capsulitis severity groups. CONCLUSIONS: Our study demonstrated that the activity of lamin A/C in maintaining nuclear structural integrity and cell viability is decreased in patients with adhesive capsulitis. The phase of the pathogenetic process (freezing and early frozen) is the key factor for cell functionality. On the contrary, the clinical severity of adhesive capsulitis plays a marginal role in nuclear stability. LEVEL OF EVIDENCE: III.

PD-L1 testing in metastatic triple negative breast cancer: Results of an Italian survey.

BACKGROUND: Immunotherapy has revolutionized the approach to metastatic triple-negative breast cancers. Atezolizumab was approved for patients with metastatic triple-negative breast cancers whose tumors express PD-L1, determined by SP 142 assay. To assess the availability and practice of SP142 test we administered a survey to all the 15 pathology departments of the Lazio Region during a six-month period. METHODS: The survey comprised 12 questions regarding the availability of SP142 in the pathology departments, the percentage of positive tests, the difficulties of pathologists in cases close to cut-off value and the tested samples. RESULTS: The SP142 assay was available in only eight centers. In case of positive result, most centers (5/8, 62.5%) reported values of PD-L1 expression ranging from > 1 to ⩽ 5%, with values close to the cut-off point (⩾ 1% or < 1%) being the greatest challenge.Most of the centers (6/8, 75%) tested material from both their own and other hospitals. In most centers, the evaluations were performed either on primary tumors or metastasis, in particular lymph nodes (5/8, 62.5%), followed by lung (3/8, 37.5%) and liver (1/8, 12.5%) metastasis. CONCLUSION: Our results raise some important issues concerning the evaluation of PD-L1 in the "real-life" setting, providing strategies for its implementation.

Xanthoma of rib: a case report and review of the literature.

BACKGROUND: Xanthomas are well-circumscribed benign proliferative lesions seen mainly in soft tissues. Usually, they are found in hyperlipidemia and familial hyperlipoproteinemia. Histologically, are characterized by macrophage-like mononuclear cells, multinucleated giant cells and abundant foam cells. The bone involvement, however, is notoriously rare and rib localization is extremely rare. CASE PRESENTATION: A 55-year-old man performed a chest X-ray and a subsequent chest Computed Tomography scan showing a rib lesion that was surgically removed and a diagnosis of rib xanthoma was made. The patient presented an unknown condition of hyperlipidemia. CONCLUSION: Rib xanthoma can be discovered accidentally and can be helpful in identifying an unrecognized condition of hyperlipidemia.

Risk of Oral Squamous Cell Carcinoma in One Hundred Patients with Oral Lichen Planus: A Follow-Up Study of Umberto I University Hospital of Rome.

This study aims to retrospectively assess the potential risk of malignant transformation in patients with diagnosed oral lichen planus (OLP) between 2015 and 2022, and to evaluate the influence of different risk factors. The department's database and medical records from 2015 to 2022 were searched for patients with a confirmed diagnosis of OLP based on both clinical and histological parameters. A total of 100 patients (59 females and 41 males) were found with a mean age of 64.03 years. In the considered period, the percentage of diagnosed OLP patients was 1.6%, while the percentage of diagnosed OLP patients with transformation to oral squamous cell carcinoma (OSCC) was 0.18%. A statistically significant difference was found with age (p = 0.038), tobacco status (p = 0.022), and radiotherapy (p = 0.041). The analysis revealed the presence of significant risk in ex-smokers (>20 pack-years), with an odds ratio (OR) of 10.0000 (95% confidence interval (95% CI) 1.5793-63.3186); in alcohol-drinker patients, with an OR of 4.0519 (95% CI 1.0182-16.1253); in ex-smoker and alcohol-drinker patients, with OR of 17.6250 (95% CI 2.2464-138.2808); and in patients who had undergone radiotherapy, with OR of 6.3000 (95% CI 1.2661-31.3484). The malignant transformation of oral lichen planus was slightly higher than thought, and the results revealed a possible association with age, tobacco and alcohol status, and history of radiotherapy. An elevated risk of malignant transformation was observed in heavy ex-smoker patients, alcohol-drinker patients, and alcohol-drinker patients with a history of smoking (ex-smokers). Persuading the patient to quit tobacco and alcohol consumption and periodic follow-ups are recommended in general, but particularly in the presence of these risk factors.

Therapeutic Choices for Genitourinary Syndrome of Menopause (GSM) in Breast Cancer Survivors: A Systematic Review and Update.

(1) Background: Genitourinary syndrome of menopause (GSM) is a medical condition that can affect breast cancer survivors (BCS). This is a complication that often can occur as a result of breast cancer treatment, causing symptoms such as vaginal dryness, itching, burning, dyspareunia, dysuria, pain, discomfort, and impairment of sexual function. BCS who experience these symptoms negatively impact multiple aspects of their quality of life to the point that some of them fail to complete adjuvant hormonal treatment; (2) Methods: In this systematic review of the literature, we have analyzed possible pharmacological and non-pharmacological treatments for GSM in BCS. We reviewed systemic hormone therapy, local hormone treatment with estrogens and androgens, the use of vaginal moisturizers and lubricants, ospemifene, and physical therapies such as radiofrequency, electroporation, and vaginal laser; (3) Results: The data available to date demonstrate that the aforementioned treatments are effective for the therapy of GSM and, in particular, vulvovaginal atrophy in BCS. Where possible, combination therapy often appears more useful than using a single line of treatment; (4) Conclusions: We analyzed the efficacy and safety data of each of these options for the treatment of GSM in BCS, emphasizing how often larger clinical trials with longer follow-ups are needed.

Magnetic resonance imaging-radiomics in endometrial cancer: a systematic review and meta-analysis.

OBJECTIVE: Endometrial carcinoma is the most common gynecological tumor in developed countries. Clinicopathological factors and molecular subtypes are used to stratify the risk of recurrence and to tailor adjuvant treatment. The present study aimed to assess the role of radiomics analysis in pre-operatively predicting molecular or clinicopathological prognostic factors in patients with endometrial carcinoma. METHODS: Literature was searched for publications reporting radiomics analysis in assessing diagnostic performance of MRI for different outcomes. Diagnostic accuracy performance of risk prediction models was pooled using the metandi command in Stata. RESULTS: A search of MEDLINE (PubMed) resulted in 153 relevant articles. Fifteen articles met the inclusion criteria, for a total of 3608 patients. MRI showed pooled sensitivity and specificity 0.785 and 0.814, respectively, in predicting high-grade endometrial carcinoma, deep myometrial invasion (pooled sensitivity and specificity 0.743 and 0.816, respectively), lymphovascular space invasion (pooled sensitivity and specificity 0.656 and 0.753, respectively), and nodal metastasis (pooled sensitivity and specificity 0.831 and 0.736, respectively). CONCLUSIONS: Pre-operative MRI-radiomics analyses in patients with endometrial carcinoma is a good predictor of tumor grading, deep myometrial invasion, lymphovascular space invasion, and nodal metastasis.

The adjusted Global Anti-Phospholipid Syndrome Score as predictor of damage accrual measured by Damage Index for APS: a longitudinal study.

OBJECTIVE: To analyse the association between the average 'adjusted' Global APS Score (aGAPSS) over time, as a surrogate of disease activity, and change in Damage Index for APS (DIAPS) during follow-up in patients with thrombotic and non-thrombotic APS. METHODS: Two hundred APS patients (138 primary, 62 associated to other autoimmune diseases) were included. DIAPS change was calculated as the difference between basal DIAPS and DIAPS at the end of follow-up. The aGAPSS was calculated for each patient at baseline and on a yearly basis for up to 6 years (minimum 3 years). The average score per patient was computed and considered the reference aGAPSS. Linear regression models were designed to analyse the association between mean aGAPSS and DIAPS change. Moreover, factors associated to high (increase of DIAPS ≥1 during follow-up) vs low (increase of DIAPS <1 during follow-up) damage accrual were assessed. RESULTS: A higher mean aGAPSS value was associated to a DIAPS increase during follow-up (b = 0.04, P < 0.001) in the multivariate analysis. Higher mean aGAPSS values were found in patients with a DIAPS increase ≥1 during follow-up compared with patients with an increase of <1 point [9.22 (95% CI 7.58, 10.86) vs 6.72 (95% CI 6.0, 7.43), P = 0.003]. aGAPSS increased the odds a DIAPS increment of ≥1 point during follow-up [OR = 1.12 (95% CI 1.04, 1.21), P = 0.003]. CONCLUSIONS: Our data support the utility of longitudinal assessing of the aGAPSS score in predicting damage accrual, measured by DIAPS, in APS.

Predictive value of the adjusted Global Anti-Phospholipid Syndrome Score on clinical recurrence in APS patients: a longitudinal study.

OBJECTIVE: To assess the effect of the average adjusted global APS score (aGAPSS) over time on recurrence of clinical manifestations in APS patients through a retrospective longitudinal study. MATERIAL AND METHODS: The study included 200 patients with APS. The aGAPSS was calculated for each patient at baseline and on a yearly basis for either up to 6 years (minimum 3 years) or just before the clinical event in patients who experienced clinical recurrence. The mean score per patient was computed. In patients under vitamin K antagonists (VKA) the percentage of time spent within the therapeutic range (TTR) was calculated. Cox regression analysis was performed to determine the cut-off value of the aGAPSS with the strongest association with clinical recurrence. RESULTS: Higher average aGAPSS values were found in patients who experienced clinical recurrence in comparison to patients who did not [8.81 (95% CI 7.53, 10.08) vs 6.38 (95% CI 5.64, 7.12), P = 0.001], patients with thrombotic recurrence compared with patients with obstetric recurrence [9.48 (95% CI 8.14, 10.82) vs 4.25 (95% CI 0.85, 7.65), P = 0.006] and patients with arterial thrombosis compared with patients with venous thrombosis [10.66 (S.D. 5.48) vs 6.63 (S.D. 4.42), P = 0.01]. aGAPSS values >13 points were associated with the highest risk of recurrence in multivariate analysis [HR = 3.25 (95% CI 1.93, 5.45), P < 0.0001]. TTR was not statistically different between patients who had thrombosis recurrence and patients who had not. CONCLUSIONS: Our data support the role of periodic (annual) monitoring of the aGAPSS score in predicting clinical recurrence in patients with APS.

MRI- and Histologic-Molecular-Based Radio-Genomics Nomogram for Preoperative Assessment of Risk Classes in Endometrial Cancer.

High- and low-risk endometrial carcinoma (EC) differ in whether or not a lymphadenectomy is performed. We aimed to develop MRI-based radio-genomic models able to preoperatively assess lymph-vascular space invasion (LVSI) and discriminate between low- and high-risk EC according to the ESMO-ESGO-ESTRO 2020 guidelines, which include molecular risk classification proposed by "ProMisE". This is a retrospective, multicentric study that included 64 women with EC who underwent 3T-MRI before a hysterectomy. Radiomics features were extracted from T2WI images and apparent diffusion coefficient maps (ADC) after manual segmentation of the gross tumor volume. We constructed a multiple logistic regression approach from the most relevant radiomic features to distinguish between low- and high-risk classes under the ESMO-ESGO-ESTRO 2020 guidelines. A similar approach was taken to assess LVSI. Model diagnostic performance was assessed via ROC curves, accuracy, sensitivity and specificity on training and test sets. The LVSI predictive model used a single feature from ADC as a predictor; the risk class model used two features as predictors from both ADC and T2WI. The low-risk predictive model showed an AUC of 0.74 with an accuracy, sensitivity, and specificity of 0.74, 0.76, 0.94; the LVSI model showed an AUC of 0.59 with an accuracy, sensitivity, and specificity of 0.60, 0.50, 0.61. MRI-based radio-genomic models are useful for preoperative EC risk stratification and may facilitate therapeutic management.

Visual Thinking Strategies as a Tool for Reducing Burnout and Improving Skills in Healthcare Workers: Results of a Randomized Controlled Study.

Objective: The purpose of this study was to measure the effect that a learning method using art, such as Visual Thinking Strategies, can have on nursing students and residents in Hygiene and Preventive Medicine; we also aimed to improve skills of observation, communication, empathy and collaboration with the patient and other team members, and evaluate the impact on quality of life, burnout and positivity. Methods: The experimentation was based on administering a form (written assessment) before and after the intervention, to measure the impact of the method on improving some useful skills for the nursing and medical professions by inserting one image of an artistic type and the other of a clinical type, and asking participants to answer basic questions on the VTS method. Students participated in groups of eight in 90-min sessions for four meetings in the classroom and one at the museum, on a weekly basis. Results: The experimental study concerned a randomized controlled sample involving undergraduate nursing students who voluntarily participated in the survey. 84 students took part in the study, including 50 undergraduate nursing students (mean age 22.5, SD 2.7; 14 males and 34 females) and 34 residents in Hygiene and Preventive Medicine (mean age 28.7, SD 2.6; 8 males and 26 females). For the artistic image, the median of the total score for all skills was -1.5 for the control group and 3 for the intervention group (p = 0.002), registering an increase for the Delta identified items, which was -1.5 for the control group and 1 for the intervention group (p = 0.007). For the clinical image, the median of the total score for all skills was 0 for the control group and 2 for the intervention group (p = 0.025), recording an increase for Delta observation skills, found to be 0 for the control group and 1 for the intervention group (p = 0.007). Conclusions: Most students who participated in the intervention reported considerable improvements in the skills the method promises to improve, and a reduction in personal and work burnout scores, suggesting that the use of the VTS method in health professions curricula is viable.

Genomic and Immune Approach in Platinum Refractory HPV-Negative Head and Neck Squamous Cell Carcinoma Patients Treated with Immunotherapy: A Novel Combined Profile.

INTRODUCTION: Only a minority of patients with platinum refractory head and neck squamous cell carcinoma (PR/HNSCC) gain some lasting benefit from immunotherapy. METHODS: The combined role of the comprehensive genomic (through the FoundationOne Cdx test) and immune profiles of 10 PR/HNSCC patients treated with the anti-PD-1 nivolumab was evaluated. The immune profiles were studied both at baseline and at the second cycle of immunotherapy, weighing 20 circulating cytokines/chemokines, adhesion molecules, and 14 soluble immune checkpoints dosed through a multiplex assay. A connectivity map was obtained by calculating the Spearman correlation between the expression profiles of circulating molecules. RESULTS: Early progression occurred in five patients, each of them showing TP53 alteration and three of them showing a mutation/loss/amplification of genes involved in the cyclin-dependent kinase pathway. In addition, ERB2 amplification (1 patient), BRCA1 mutation (1 patient), and NOTCH1 genes alteration (3 patients) occurred. Five patients achieved either stable disease or partial response. Four of them carried mutations in PI3K/AKT/PTEN pathways. In the only two patients, with a long response to immunotherapy, the tumor mutational burden (TMB) was high. Moreover, a distinct signature, in terms of network connectivity of the circulating soluble molecules, characterizing responder and non-responder patients, was evidenced. Moreover, a strong negative and statistically significant (p-value ≤ 0.05) correlation with alive status was evidenced for sE-selectin at T1. CONCLUSIONS: Our results highlighted the complexity and heterogeneity of HNSCCs, even though it was in a small cohort. Molecular and immune approaches, combined in a single profile, could represent a promising strategy, in the context of precision immunotherapy.

Persistence of antiphospholipid antibodies over time and its association with recurrence of clinical manifestations: A longitudinal study from a single centre.

PURPOSE: To analyze the antiphospholipid antibody (aPL) persistence over time in patients with antiphospholipid syndrome (APS) and its association with clinical recurrence and to identify predictors of aPL persistence over time. PATIENTS AND METHODS: 200 patients with a diagnosis of APS and at least three follow-up aPL determinations were included. Persistent aPL profile was defined as the presence of lupus anticoagulant (LAC) and/or IgG/IgM anticardiolipin (aCL) and/or IgG/IgM anti-ß2 glycoprotein-I (aß2GPI) (> 99th percentile) antibodies in at least 66% of follow-up measurements. Multilevel mixed-effect generalized linear models with logit link were used. RESULTS: 112 (56%) patients maintained persistent aPL profiles over time, while 88 (44%) were transient. Median follow-up time was 172.5 months. Follow-up time did not affect the odds of aPL persistence in multivariate analysis (p = 1.00). Baseline triple aPL positivity [OR 78 (95%CI 16.9-359.7, p < 0.001)] and double aPL positivity [OR = 7.6 (95%CI 3.7-15.7, p < 0.001)] correlated with persistent aPLs over time, while isolated LAC [OR = 0.26 (95% CI 0.08-0.49, p = 0.002)] or isolated IgG/IgM aCL [OR = 0.20 (95% CI 0.11-0.59, p = 0.004)] positivity, were predictors of transient aPL profile. Patients with persistent aPLs had higher rate of clinical recurrence in comparison to patients with transient aPLs [OR = 2.48 (95%CI 1.34-4.58, p = 0.003)]. CONCLUSIONS: More than half of patients with baseline medium-high titer aPL positivity had persistent positive aPLs over time. Patients with persistent aPLs were more prone to present recurrence of clinical manifestations. Multiple aPL positivity increased the odds of a persistent aPL profile over time, while isolated LAC and aCL positivity decreased it.

A Regional Survey on Merkel Cell Carcinoma: A Plea for Uniform Patient Journey Modeling and Diagnostic-Therapeutic Pathway.

Merkel cell carcinoma (MCC) is a rare and aggressive cutaneous neuroendocrine cancer that usually affects the elderly and immunosuppressed in sun-exposed areas. Due to its rarity, it is frequently unrecognized, and its management is not standardized across medical centers, despite the more recent availability of immunotherapy, with avelumab as first-line treatment improving the prognosis even in advanced stages of disease. We conducted a purpose-designed survey of a selected sample of physicians working in the Lazio region, in Italy, to assess their awareness and knowledge of MCC as well as their perspective on assisted diagnostic and therapeutic pathways. The Lazio region, and in particular Rome, is one of the most important academic and non- academic center in Italy dedicated to the diagnosis and treatment of skin cancer. A total of 368 doctors (including 100 general practitioners, 72 oncologists, 87 dermatologists, 59 surgeons, and 50 anatomopathologists) agreed to be part of this survey. Surgeons, oncologists, and dermatologists thought themselves significantly more updated on MCC than primary care physicians, but more than half of the interviewees are interested in CCM training courses and training with clearer and more standardized care pathways. Significant differences have been reported from survey participants in terms of multidisciplinary team set up for MCC management. The identification of specialized centers and the improvement of communication pathways among different specialties, as well as between patients and physicians, could be very beneficial in improving patients' journey modeling and starting a uniform diagnostic and therapeutic pathway for MCC patients in the new era of immunotherapies.

Extremely late-onset pulmonary metastasis from uterine PEComa.

A 79-year-old woman underwent surgical resection of a peripheral, solitary, pulmonary lesion that was diagnosed as malignant PEComa. Her clinical history was positive for uterine leiomyosarcoma, excised 20 years before. Re-evaluation of the primary uterine lesion led to the final diagnosis of lung metastasis from uterine PEComa. While long latency between primary tumour and metastasis is a known and characteristic feature of PEComas, a 20-year interval is unprecedented in the literature.

Time for Revival of Bone Biopsy with Histomorphometric Analysis in Chronic Kidney Disease (CKD): Moving from Skepticism to Pragmatism.

Bone Biopsy (BB) with histomorphometric analysis still represents the gold standard for the diagnosis and classification of different forms of renal osteodystrophy. Bone biopsy is the only technique able to provide comprehensive information on all bone parameters, measuring static and dynamic parameters of turnover, cortical and trabecular microarchitecture, and mineralization defects. In nephrological practice, bone biopsy yields relevant indications to support therapeutic choices in CKD, heavily impacting the management and prognosis of uremic patients. Unfortunately, the use of bone biopsy has decreased; a lack of expertise in performing and interpreting, perceived procedure invasiveness and pain, and reimbursement issues have all contributed to this decline. Nevertheless, both bone biomarkers and instrumental images cannot be considered reliable surrogates for histological findings, being insufficiently accurate to properly evaluate underlying mineral and bone disorders. This is a multidisciplinary position paper from the Nephrology and Osteoporosis Italian Scientific Societies with the purpose of restating the role of bone biopsy in CKD patient management and of providing strong solutions to allow diffusion of this technique in Italy, but potentially also in other countries. The Italian approach through the optimization and standardization of bone biopsy procedure, the construction of the Italian Hub and Spoke network, and a request for adjustment and national homogenization of reimbursement to the Italian Health Ministry has led the way to implement bone biopsy and to improve CKD patient management and prognosis.

Systemic sclerosis and pregnancy outcomes: a retrospective study from a single center.

BACKGROUND: Pregnancy in systemic sclerosis (SSc) patients is no more an infrequent event as it used to be, but literature data on pregnancy outcomes in women with SSc are scarce. The rate of preterm deliveries and intrauterine growth restriction (IUGR) seems to be increased, while the risk of miscarriages is controversial. Moreover, no study compared pregnancy outcomes in SSc with antiphospholipid syndrome (APS) and systemic lupus erythematosus (SLE). We performed a retrospective study to compare the pregnancy and disease outcomes of women with SSc with a cohort of age-matched women with systemic lupus erythematosus (SLE), antiphospholipid syndrome (APS), and healthy controls (HC). METHODS: A total of 154 pregnancies from SSc, SLE, APS patients, and HC were prospectively followed at the High-Risk Pregnancy Unit of our center from 2008 to 2019. The primary outcome was a composite endpoint of miscarriages, fetal deaths, intrauterine growth restriction (IUGR), preeclampsia, neonatal deaths, preterm birth, and small-for-gestational-age (SGA) newborns. Single adverse pregnancy outcomes (APO) represented secondary endpoints. SSc activity variations in relation to pregnancy were assessed. RESULTS: The risk of APO was significantly higher in SSc patients compared to HC (60.6% vs 10.0%; OR = 14.42; 95% CI 3.70-56.18, p = 0.001) and SLE patients (60.6% vs 37.5%; OR = 3.56; 95% CI 1.29-9.83, p = 0.014). Compared to HC, women with SSc had an increased frequency of first trimester miscarriage (15% vs 0 %; p = 0.016), preeclampsia (12% vs 0%, p = 0.038), and SGA newborns (21.2% vs 0%; p = 0.003). Preterm deliveries were more frequent in SSc pregnancies in comparison with HC (24.2% vs 5%; OR = 6.08; 95% CI 1.19-31.02, p = 0.036) and SLE patients (24.2% vs 7.5%, OR = 5.68; 95% CI 1.1-29.38, p = 0.038). Disease remained stable in all SSc patients during pregnancy and up to 1 year after delivery. CONCLUSIONS: We found an increased risk of APO in our SSc cohort in comparison with HC (with higher rates of miscarriages, preeclampsia, SGA newborns, and preterm deliveries) and SLE patients (presenting a higher rate of preterm deliveries). High-risk multidisciplinary management of SSc pregnant women is highly recommended.

Intravoxel Incoherent Motion (IVIM) MR Quantification in Locally Advanced Cervical Cancer (LACC): Preliminary Study on Assessment of Tumor Aggressiveness and Response to Neoadjuvant Chemotherapy.

The aim of this study was to determine whether quantitative parameters obtained from intravoxel incoherent motion (IVIM) model at baseline magnetic resonance imaging (MRI) correlate with histological parameters and response to neoadjuvant chemotherapy in patients with locally advanced cervical cancer (LACC). METHODS: Twenty patients with biopsy-proven cervical cancer, staged as LACC on baseline MRI and addressed for neoadjuvant chemotherapy were enrolled. At treatment completion, tumor response was assessed with a follow-up MRI evaluated using the revised response evaluation criteria in solid tumors (RECIST; version 1.1), and patients were considered good responders (GR) if they had complete response or partial remission, and poor responders/non-responders (PR/NR) if they had stable or progressive disease. MRI protocol included conventional diffusion-weighted imaging (DWI; b = 0 and 1000 s/mm2) and IVIM acquisition using eight b-values (range: 0-1500 s/mm2). MR-images were analyzed using a dedicated software to obtain quantitative parameters: diffusion (D), pseudo-diffusion (D*), and perfusion fraction (fp) from the IVIM model; apparent diffusion coefficient (ADC) from conventional DWI. Histologic subtype, grading, and tumor-infiltrating lymphocytes (TILs) were assessed in each LACC. RESULTS: D showed significantly higher values in GR patients (p = 0.001) and in moderate/high TILs (p = 0.018). Fp showed significantly higher values in squamous cell tumors (p = 0.006). CONCLUSIONS: D extracted from the IVIM model could represent a promising tool to identify tumor aggressiveness and predict response to therapy.

HPV Vaccination after Primary Treatment of HPV-Related Disease across Different Organ Sites: A Multidisciplinary Comprehensive Review and Meta-Analysis.

OBJECTIVE: To assess evidence on the efficacy of adjuvant human papillomavirus (HPV) vaccination in patients treated for HPV-related disease across different susceptible organ sites. METHODS: A systematic review was conducted to identify studies addressing the efficacy of adjuvant HPV vaccination on reducing the risk of recurrence of HPV-related preinvasive diseases. Results were reported as mean differences or pooled odds ratios (OR) with 95% confidence intervals (95% CI). RESULTS: Sixteen studies were identified for the final analysis. Overall, 21,472 patients with cervical dysplasia were included: 4132 (19.2%) received the peri-operative HPV vaccine, while 17,340 (80.8%) underwent surgical treatment alone. The recurrences of CIN 1+ (OR 0.45, 95% CI 0.27 to 0.73; p = 0.001), CIN 2+ (OR 0.33, 95% CI 0.20 to 0.52; p < 0.0001), and CIN 3 (OR 0.28, 95% CI 0.13 to 0.59; p = 0.0009) were lower in the vaccinated than in unvaccinated group. Similarly, adjuvant vaccination reduced the risk of developing anal intraepithelial neoplasia (p = 0.005) and recurrent respiratory papillomatosis (p = 0.004). No differences in anogenital warts and vulvar intraepithelial neoplasia recurrence rate were observed comparing vaccinated and unvaccinated individuals. CONCLUSIONS: Adjuvant HPV vaccination is associated with a reduced risk of CIN recurrence, although there are limited data regarding its role in other HPV-related diseases. Further research is warranted to shed more light on the role of HPV vaccination as adjuvant therapy after primary treatment.

Prognostic impact of spread through air spaces in lung adenocarcinoma.

OBJECTIVE: Spread through air spaces (STAS) is a pattern of invasion present in some adenocarcinomas (ADC). The goal of this study was to assess the impact of STAS in patients treated with different types of surgical resections and on the clinical outcome in patients with ADC of different diameters and with different degrees of nodal involvement. METHODS: A total of 109 patients were reviewed. Complete surgical resection with systematic nodal dissection was achieved in all patients. The median follow-up was 65 months (3-90 months). RESULTS: STAS was observed in 70 cases (64.2%); 13 patients (18.5%) had lymph node involvement (N1 and N2). Overall survival and progression-free survival were higher in patients without STAS (P = 0.042; P = 0.027). The presence of STAS in tumours ≤2 cm was a predictor of worse progression-free survival following sublobar resection compared to major resections (P = 0.011). Sublobar resection of N0 STAS-positive tumours was associated with worse long-term survival compared to a major resection (P = 0.04). Statistical analyses showed that age >70 years and recurrence were independent variables for survival; smoking pack-years >20, sublobar resection and nodal involvement were independent variables for recurrence; and smoking pack-years >20 were independent variables for a history of cancer and pleural invasion for local recurrence. CONCLUSIONS: STAS seems to play a role in long-term survival, particularly for patients with N0 and tumours smaller than 2 cm. Further studies are necessary to validate this hypothesis.
