Safety of pregnancy after breast cancer in young women with hormone receptor-positive disease: a systematic review and meta-analysis. ESMO Open 2023; 8:102031. [PMID: 37879234 PMCID: PMC10774870 DOI: 10.1016/j.esmoop.2023.102031] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2023] [Accepted: 09/13/2023] [Indexed: 10/27/2023] Open
Abstract
BACKGROUND Despite increasing evidence on the safety of pregnancy after anticancer treatments in breast cancer survivors, many physicians and patients remain concerned about a potential risk of pregnancy specifically in the case of hormone receptor-positive breast cancer. MATERIALS AND METHODS A systematic literature search of Medline, Embase and Cochrane library with no language or date restriction up to 31 March 2023 was carried out. To be included, articles had to be retrospective and prospective case-control and cohort studies as well as clinical trials comparing survival outcomes of premenopausal women with or without a pregnancy after prior diagnosis of hormone receptor-positive breast cancer. Disease-free survival (DFS) and overall survival (OS) were the outcomes of interest. Pooled hazard ratios (HRs) with 95% confidence intervals (CIs) were calculated. Study protocol is registered in PROSPERO (n. CRD42023394232). RESULTS Out of 7796 screened studies, 8 were eligible to be included in the final analysis. A total of 3805 patients with hormone receptor-positive invasive early breast cancer were included in these studies, of whom 1285 had a pregnancy after breast cancer diagnosis. Median follow-up time ranged from 3.8 to 15.8 years and was similar in the pregnancy and non-pregnancy cohorts. In three studies (n = 987 patients) reporting on DFS, no difference was observed between patients with and those without a subsequent pregnancy (HR 0.96, 95% CI 0.75-1.24, P = 0.781). In the six studies (n = 3504 patients) reporting on OS, patients with a pregnancy after breast cancer had a statistically significant better OS than those without a pregnancy (HR 0.46, 95% CI 0.27-0.77, P < 0.05). CONCLUSIONS This systematic review and meta-analysis of retrospective cohort studies provides updated evidence that having a pregnancy in patients with prior history of hormone receptor-positive invasive early breast cancer appears safe without detrimental effect on prognosis.

Protective ileostomy after low anterior resection for extraperitoneal rectal cancer: does the reversal surgery timing affect closure failure? Updates Surg 2023; 75:1811-1818. [PMID: 37428410 DOI: 10.1007/s13304-023-01573-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2023] [Accepted: 06/22/2023] [Indexed: 07/11/2023]
Abstract
Loop ileostomy is commonly performed after LAR with TME to temporarily protect the anastomosis. Usually, defunctioning stoma is closed after 1-6 months, although sometimes it becomes definitive de facto. The aim of this study is to investigate the long-term risk of no-reversal of protective ileostomy after LAR for middle-low rectal cancer and the predictive risk factors. A retrospective analysis of a consecutive cohort of patients who underwent curative LAR with covering ileostomy for extraperitoneal rectal cancer in two colorectal units was performed. A different policy for scheduling stoma closure was applied between centers. All the data were collected through an electronic database (Microsoft Excel®). Descriptive statistical analysis was performed using Fisher's exact and Student's t test. Multivariate logistic regression analysis was conducted. Two-hundred twenty-two patients were analysed: reversal procedure was carried out in 193 patients, in 29 cases stoma was never closed. The mean interval time from index surgery was 4.9 months (Center1: 3 vs. Center2: 7.8). At the univariate analysis, mean age and tumor stage were significantly higher in the "no-reversal" group. Unclosed ostomies were significantly lower in Center 1 than Center 2 (8% vs. 19.6%). At the multivariate analysis female gender, anastomotic leakage and Center 2 had significant higher risk of unclosed ileostomy. Currently, no clinical recommendations have been established and the policy of scheduling stoma reversal is variable. Our study suggests that an established protocol could avoid closure delay, decreasing permanent stomas. Consequently, ileostomy closure should be weighed as standardized step in cancer therapeutic pathway.

Prognostic value of HER2-low status in breast cancer: a systematic review and meta-analysis. ESMO Open 2023; 8:101592. [PMID: 37413762 PMCID: PMC10485402 DOI: 10.1016/j.esmoop.2023.101592] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2023] [Revised: 05/30/2023] [Accepted: 05/31/2023] [Indexed: 07/08/2023] Open
Abstract
BACKGROUND Human epidermal growth factor receptor 2 (HER2)-low expression in breast cancer has been recently identified as a new therapeutic target. However, it is unclear if HER2-low status has an independent impact on prognosis. MATERIALS AND METHODS A systematic literature research was carried out to identify studies comparing survival outcomes of patients affected by HER2-low versus HER2-zero breast cancer. Using random-effects models, pooled hazard ratios (HRs) and odds ratios (ORs) with 95% confidence intervals (CIs) were calculated for progression-free survival (PFS) and overall survival (OS) in the metastatic setting as well as disease-free survival (DFS), OS and pathological complete response (pCR) in the early setting. Subgroup analyses by hormone receptor (HoR) status were carried out. The study protocol is registered on PROSPERO (n.CRD42023390777). RESULTS Among 1916 identified records, 42 studies including 1 797 175 patients were eligible. In the early setting, HER2-low status was associated with significant improved DFS (HR 0.86, 95% CI 0.79-0.92, P < 0.001) and OS (HR 0.90, 95% CI 0.85-0.95, P < 0.001) when compared to HER2-zero status. Improved OS was observed for both HoR-positive and HoR-negative HER2-low populations, while DFS improvement was observed only in the HoR-positive subgroup. HER2-low status was significantly associated with a lower rate of pCR as compared to HER2-zero status both in the overall population (OR 0.74, 95% CI 0.62-0.88, P = 0.001) and in the HoR-positive subgroup (OR 0.77, 95% CI 0.65-0.90, P = 0.001). In the metastatic setting, patients with HER2-low breast cancers showed better OS when compared with those with HER2-zero tumours in the overall population (HR 0.94, 95% CI 0.89-0.98, P = 0.008), regardless of HoR status. No significant PFS differences were found. CONCLUSIONS Compared with HER2-zero status, HER2-low status appears to be associated with a slightly increased OS both in the advanced and early settings, regardless of HoR expression. In the early setting, HER2-low tumours seem to be associated to lower pCR rates, especially if HoR-positive.

Abstract
Abstract
Background
Bone marrow-derived macrophages account for substantial GBM tumor volume and contribute to the local inflammatory tumor microenvironment, disease progression and treatment response.
Material and Methods
We have developed a genetically modified, autologous hematopoietic stem cell-based platform designed to deliver Interferon-alpha (IFNa), thanks to a transcriptional and post-transcriptional control mechanism mediated by miRNA target sequences, specifically into the tumor microenvironment via Tie-2 expressing monocytes (Temferon).
Results
As of Feb 2022, 3 escalating doses of Temferon (from 0.5 to 2.0x106/kg) were tested across 15 patients with newly diagnosed, unmethylated MGMT glioblastoma (GBM) assigned to 5 cohorts. The duration of follow-up from surgery is 6 - 28 mo (2 - 25 mo after Temferon). To date, no dose limiting toxicities have been identified. As expected, one month after the administration of the highest tested dose, the hematopoietic system of Temferon-treated patients was composed of up to 30% of CD14+ genetically modified cells, as determined by the presence of vector genomes in the DNA in peripheral blood and bone marrow cells. Temferon-derived progeny persisted, albeit at lower levels, up to 18 months (longest time of analysis). Despite the substantial proportion of engineered cells, very low median concentrations of IFNα were detected in the plasma (D+30, 5.9; D+90, 8.8pg/mL) and in the CSF (D+30, 1.5; D+90, 2.4pg/mL), indicating tight regulation of transgene expression. SAEs were mostly attributed to conditioning chemotherapy (e.g. infections) or disease progression (e.g. seizures). 1 SUSAR (persistent GGT elevation) has occurred. Median OS is 15 mo from surgery (range 6.1-28.4 mo; 10.8 mo post Temferon). Of the 15 pts treated so far, 4 pts belonging to low dose cohorts underwent 2nd surgery. Homing of transduced cells from BM to the tumor site was demonstrated by the presence of gene-marked cells in the specimens collected from 3 of the 4 analyzed pts. Single-cell RNA seq performed on CD45+ cells purified from the TME of Temferon-treated pts compared to recurrent tumors belonging to GBM pts treated as per the current standard of care, highlighted a Temferon signature defined by the induction of markers of IFNa responses and macrophage repolarization. Potential long-term benefit with Temferon was identified in a patient from cohort 3, who had disease progression at D+120 with two distant enhancing lesions, and increased tumor necrosis. One year following Temferon, with no 2nd line therapy added, there was approximately 40% reduction in enhancing tumor volume compared to D+180 with a stable clinical and imaging picture thereafter.
Conclusion
The results provide initial evidence of Temferon’s potential to modulate the TME of GBM patients, and anecdotal evidence for long lasting effects of Temferon in prevention of disease progression.

Seminal plasma N-glycome as a new biomarker of environmental exposure associated with semen quality. Reprod Toxicol 2022; 113:96-102. [PMID: 35961531 DOI: 10.1016/j.reprotox.2022.08.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/07/2022] [Revised: 07/27/2022] [Accepted: 08/07/2022] [Indexed: 11/25/2022]
Abstract
Male infertility, a condition that has during the last decade raised significant concern, is a diagnostically demanding and socially sensitive topic. The number of unsolved issues on infertility etiology, especially potential environmental causes, in couples demonstrates the need for further investigations into infertility biomarkers. Semen parameters are often insufficient for reliable profiling of male infertility. Thus, this study aims to evaluate for the first time seminal plasma N-glycosylation as a biomarker of environmental exposure in semen samples from 82 normozoospermic men and 84 men with abnormal semen parameters and compare it with genome damage measured by DNA fragmentation. We obtained information about chronic exposure to environmental factors from the self-reported questionnaire, and determined sperm DNA fragmentation by sperm chromatin dispersion, while N-glycans were characterized with liquid chromatography-mass spectrometry (LC-MS). Based on previously published results, ten N-glycans were selected. Results show that the selected seminal plasma N-glycans were significantly associated with smoking, exposure to pesticides, air pollution, agents emitted during photocopying, alcohol consumption, and obesity. Some N-glycans showed a simultaneous association with DNA fragmentation, semen parameters, and environmental stressors. These subgroups of N-glycans are new potential candidates for biomonitoring of exposure to different environmental factors in men with semen abnormalities.

Efficacy of tyrosine kinase inhibitors for the treatment of patients with HER2-positive breast cancer with brain metastases: a systematic review and meta-analysis. ESMO Open 2022; 7:100501. [PMID: 35653982 PMCID: PMC9160675 DOI: 10.1016/j.esmoop.2022.100501] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/05/2022] [Accepted: 04/09/2022] [Indexed: 12/03/2022] Open
Abstract
Background Brain metastases (BMs) are frequent events in patients with HER2-positive metastatic breast cancer (MBC) and are associated with poor prognosis. Small-molecule anti-HER2 tyrosine kinase inhibitors (TKIs) are promising agents for the treatment of BM. In this study, we assess the clinical outcomes of patients with HER2-positive MBC and BM treated with TKI-containing regimens compared with those treated with non-TKI-containing regimens. Materials and methods PubMed, Embase, Cochrane Library, and conference proceedings (ASCO, SABCS, ESMO, and ESMO Breast) were searched up to June 2021. The primary endpoint was progression-free survival (PFS) in patients with BM. Secondary endpoints included PFS in patients without BM and overall survival (OS). The study was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Overall effects were pooled using random-effects models. Results This systematic review and meta-analysis included data from 2437 patients (490 with and 1947 without BM at baseline) enrolled in five trials assessing tucatinib-, lapatinib-, pyrotinib-, or afatinib-based combinations. A nonstatistically significant PFS benefit favoring TKI-containing regimens was observed in both patients with BM [hazard ratio (HR) 0.67, 95% confidence interval (CI) 0.41-1.12; P = 0.13] and without BM (HR 0.55, 95% CI 0.24-1.26; P = 0.16). Sensitivity analysis, excluding each study singly, demonstrated a significant PFS benefit favoring TKI-containing regimens in patients with BM after the exclusion of afatinib from the analysis (HR 0.56, 95% CI 0.35-0.90; P = 0.016). No statistically significant differences in OS were observed between the comparison groups. Conclusions A trend in PFS favoring TKI-containing regimens was observed in patients with BM. Sensitivity analysis including only trials that evaluated regimens containing tucatinib, lapatinib, or pyrotinib demonstrated a significant PFS benefit favoring TKI-containing regimens in patients with BM. The optimal therapy for HER2+ BC BMs remains unknown. Anti-HER2 TKIs are effective for treating MBC. This study examined the efficacy of TKI for the treatment of patients with BM. A trend toward improved PFS favoring TKIs was observed in patients with BM. There was no significant difference in OS between TKIs versus non-TKI regimens.

Safety of fertility preservation techniques before and after anticancer treatments in young women with breast cancer: a systematic review and meta-analysis. Hum Reprod 2022; 37:954-968. [PMID: 35220429 PMCID: PMC9071231 DOI: 10.1093/humrep/deac035] [Citation(s) in RCA: 34] [Impact Index Per Article: 17.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2021] [Revised: 01/19/2022] [Indexed: 11/25/2022] Open
Abstract
STUDY QUESTION Is it safe to perform controlled ovarian stimulation (COS) for fertility preservation before starting anticancer therapies or ART after treatments in young breast cancer patients? SUMMARY ANSWER Performing COS before, or ART following anticancer treatment in young women with breast cancer does not seem to be associated with detrimental prognostic effect in terms of breast cancer recurrence, mortality or event-free survival (EFS). WHAT IS KNOWN ALREADY COS for oocyte/embryo cryopreservation before starting chemotherapy is standard of care for young women with breast cancer wishing to preserve fertility. However, some oncologists remain concerned on the safety of COS, particularly in patients with hormone-sensitive tumors, even when associated with aromatase inhibitors. Moreover, limited evidence exists on the safety of ART in breast cancer survivors for achieving pregnancy after the completion of anticancer treatments. STUDY DESIGN, SIZE, DURATION The present systematic review and meta-analysis was carried out by three blinded investigators using the keywords 'breast cancer' and 'fertility preservation'; keywords were combined with Boolean operators. Eligible studies were identified by a systematic literature search of Medline, Web of Science, Embase and Cochrane library with no language or date restriction up to 30 June 2021. PARTICIPANTS/MATERIALS, SETTING, METHODS To be included in this meta-analysis, eligible studies had to be case-control or cohort studies comparing survival outcomes of women who underwent COS or ART before or after breast cancer treatments compared to breast cancer patients not exposed to these strategies. Survival outcomes of interest were cancer recurrence rate, relapse rate, overall survival and number of deaths. Adjusted relative risk (RR) and hazard ratio (HR) with 95% CI were extracted. When the number of events for each group were available but the above measures were not reported, HRs were estimated using the Watkins and Bennett method. We excluded case reports or case series with <10 patients and studies without a control group of breast cancer patients who did not pursue COS or ART. Quality of data and risk of bias were assessed using the Newcastle-Ottawa Assessment Scale. MAIN RESULTS AND THE ROLE OF CHANCE A total of 1835 records were retrieved. After excluding ineligible publications, 15 studies were finally included in the present meta-analysis (n = 4643). Among them, 11 reported the outcomes of breast cancer patients who underwent COS for fertility preservation before starting chemotherapy, and 4 the safety of ART following anticancer treatment completion. Compared to women who did not receive fertility preservation at diagnosis (n = 2386), those who underwent COS (n = 1594) had reduced risk of recurrence (RR 0.58, 95% CI 0.46-0.73) and mortality (RR 0.54, 95% CI 0.38-0.76). No detrimental effect of COS on EFS was observed (HR 0.76, 95% CI 0.55-1.06). A similar trend of better outcomes in terms of EFS was observed in women with hormone-receptor-positive disease who underwent COS (HR 0.36, 95% CI 0.20-0.65). A reduced risk of recurrence was also observed in patients undergoing COS before neoadjuvant chemotherapy (RR 0.22, 95% CI 0.06-0.80). Compared to women not exposed to ART following completion of anticancer treatments (n = 540), those exposed to ART (n = 123) showed a tendency for better outcomes in terms of recurrence ratio (RR 0.34, 95% CI 0.17-0.70) and EFS (HR 0.43, 95% CI 0.17-1.11). LIMITATIONS, REASONS FOR CAUTION This meta-analysis is based on abstracted data and most of the studies included are retrospective cohort studies. Not all studies had matching criteria between the study population and the controls, and these criteria often differed between the studies. Moreover, rate of recurrence is reported as a punctual event and it is not possible to establish when recurrences occurred and whether follow-up, which was shorter than 5 years in some of the included studies, is adequate to capture late recurrences. WIDER IMPLICATIONS OF THE FINDINGS Our results demonstrate that performing COS at diagnosis or ART following treatment completion does not seem to be associated with detrimental prognostic effect in young women with breast cancer, including among patients with hormone receptor-positive disease and those receiving neoadjuvant chemotherapy.

Safety of assisted reproductive techniques in young women harboring germline pathogenic variants in BRCA1/2 with a pregnancy after prior history of breast cancer. ESMO Open 2021; 6:100300. [PMID: 34775302 PMCID: PMC8593447 DOI: 10.1016/j.esmoop.2021.100300] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/16/2021] [Revised: 10/06/2021] [Accepted: 10/07/2021] [Indexed: 12/24/2022] Open
Abstract
BACKGROUND Knowledge is growing on the safety of assisted reproductive techniques (ART) in cancer survivors. No data exist, however, for the specific population of breast cancer patients harboring germline BRCA1/2 pathogenic variants. PATIENTS AND METHODS This is a multicenter retrospective cohort study across 30 centers worldwide including women diagnosed at ≤40 years with stage I-III breast cancer, between January 2000 and December 2012, harboring known germline BRCA1/2 pathogenic variants. Patients included in this analysis had a post-treatment pregnancy either achieved through use of ART (ART group) or naturally (non-ART group). ART procedures included ovulation induction, ovarian stimulation for in vitro fertilization or intracytoplasmic sperm injection, and embryo transfer under hormonal replacement therapy. RESULTS Among the 1424 patients registered in the study, 168 were eligible for inclusion in the present analysis, of whom 22 were in the ART group and 146 in the non-ART group. Survivors in the ART group conceived at an older age compared with those in the non-ART group (median age: 39.7 versus 35.4 years, respectively). Women in the ART group experienced more delivery complications compared with those in the non-ART group (22.1% versus 4.1%, respectively). No other apparent differences in obstetrical outcomes were observed between cohorts. The median follow-up from pregnancy was 3.4 years (range: 0.8-8.6 years) in the ART group and 5.0 years (range: 0.8-17.6 years) in the non-ART group. Two patients (9.1%) in the ART group experienced a disease-free survival event (specifically, a locoregional recurrence) compared with 40 patients (27.4%) in the non-ART group. In the ART group, no patients deceased compared with 10 patients (6.9%) in the non-ART group. CONCLUSION This study provides encouraging safety data on the use of ART in breast cancer survivors harboring germline pathogenic variants in BRCA1/2, when natural conception fails or when they opt for ART in order to carry out preimplantation genetic testing.

Abstract
OBJECTIVE This study evaluated single intra-articular injections of Hymovis MO.RE., a hyaluronic acid hexadecyl derivative (HYADD4-G), to manage post-traumatic or degenerative knee or ankle chondropathy in professional soccer players. PATIENTS AND METHODS Twenty-five players affected by knee (n = 12) or ankle (n = 13) chondropathy were prospectively enrolled and treated by two single Hymovis MO.RE. (32 mg/4 ml) injections at the beginning of the football season (V0, baseline) and at mid-season (V1, 19-20 weeks thereafter), and were followed-up until the end of the season (V2, after further 19-20 weeks). Knee cases were evaluated using the 2000 IKDC knee subjective examination form and the modified Lysholm scoring system. Ankle cases were evaluated using the American Orthopaedic Foot Ankle Society (AOFAS) ankle-hindfoot score. Patients were also evaluated using a VAS Likert scale and a four-category scale recording both the patient's and the doctor's assessment on joint mobility in degrees and overall treatment efficacy. Adverse events, patient withdrawals and local reaction to injections were also assessed. RESULTS In knee patients, the 2000 IKDC subjective score improved from 46.8 ± 11.4 at V0 to 83.1 ± 12.5 at V2. Their modified Lysholm score improved from 58.8 ± 8.9 at V0 to 90.6 ± 8.3 at V2. In the ankle patients, the AOFAS score improved from 52.2 ± 5.6 at V0 to 96.4 ± 4.5 at V2. VAS Likert values and subjective evaluations improved at V1 and were maintained at V2. No side effects were recorded. CONCLUSIONS A single Hymovis MO.RE. (32 mg/4 ml) intra-articular injection, repeated after 19-20 weeks, may be a viable option to improve symptoms and function in professional soccer players suffering from knee and ankle chondropathy.

Beta-blockers in early-stage breast cancer: a systematic review and meta-analysis. ESMO Open 2021; 6:100066. [PMID: 33639601 PMCID: PMC7921512 DOI: 10.1016/j.esmoop.2021.100066] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/30/2020] [Accepted: 01/27/2021] [Indexed: 11/24/2022] Open
Abstract
BACKGROUND Preclinical and retrospective studies suggest that beta-blockers are active against breast cancer. We carried out a systematic review and meta-analysis to assess the impact of beta-blockers on the outcomes of patients with early-stage breast cancer. METHODS A systematic literature search was performed to identify studies comparing outcomes of patients with early-stage breast cancer according to beta-blocker use (yes versus no). The primary endpoint was recurrence-free survival (RFS), defined as the occurrence of breast cancer recurrence or death. Secondary objectives were pathologic complete response (pCR), breast cancer recurrence, breast cancer-specific mortality and overall survival (OS). Hazard ratios (HRs) or odds ratios (ORs) and 95% confidence intervals (CIs) were extracted from each study and a pooled analysis with the random-effect model was conducted. The Higgins' I-squared test was used to quantify heterogeneity. Egger's test was applied to assess publication bias. All P values were two-sided and considered significant if ≤0.05. RESULTS Overall, 13 studies were included as follows: RFS (6), pCR (2), breast cancer recurrence (6), breast cancer-specific mortality (7) and OS (5). The use of beta-blockers was associated with a significant RFS improvement in the overall population (N = 21 570; HR 0.73; 95% CI, 0.56-0.96; P = 0.025) and in patients with triple-negative disease (N = 1212; HR 0.53; 95% CI, 0.35-0.81; P = 0.003). No significant differences in terms of pCR (N = 1554; OR 0.77; 95% CI, 0.44-1.36; P = 0.371), breast cancer recurrence (N = 37 957; OR 0.66; 95% CI, 0.42-1.03; P = 0.065), breast cancer-specific mortality (N = 64 830; HR 0.77; 95% CI, 0.56-1.08; P = 0.130) or OS (N = 103 065; HR 1.03; 95% CI, 0.87-1.23; P = 0.692) were observed according to beta-blocker use. DISCUSSION In this meta-analysis, beta-blocker use was associated with a longer RFS in patients with early-stage breast cancer, with a more pronounced effect observed in those with triple-negative disease. Beta-blockers arise as an interesting option to be explored in prospective studies for patients with early-stage breast cancer.

Abstract
Abstract
Background
The negative prognostic effect of chronic kidney disease (CKD), anaemia and diabetes in patients with acute coronary syndromes is well known. However, data about the prevalence and the prognostic importance of these comorbidities in unselected, contemporary STEMI patients treated with primary PCI are limited.
Purpose
We sought to investigate the prevalence of CKD, anaemia and diabetes mellitus in this patient population, as well as possible interactions between these comorbidities.
Methods
Between January 2006 and December 2018, 3395 consecutive patients with STEMI underwent primary PCI in two centres. Hb and creatinine were determined on a blood test obtained immediately upon the arrival at the Hospital and eGFR was estimated with the CKD-EPI equation. Renal impairment (RI) was defined as stage 3B or worse CKD (eGFR ≤44 ml/min/1.73m2). Anaemia was defined as Hb <13 g/dl in males and <12 g/dl in females. The outcome measure was overall mortality at a median follow-up of 1.9 years.
Results
The age of patients was (mean±SD) 67.2±12.9 years and 27.3% of them were females. Diabetes was present in 22.1%, anaemia in 18.1%, and RI in 9.8% of patients. The presence of diabetes, anemia or RI, individually or in various combination, was associated with higher mortality (see figure). Interestingly, these comorbidities presented an addictive, but non synergistic, effect (P for interaction = NS for all combinations). The covariates associated with mortality are shown in the Table. Notably, female gender was independently associated with lower mortality.
Conclusions
In contemporary patients treated with primary PCI, diabetes, anaemia and RI are frequently present, individually or in combination. All these comorbidities are strong independent predictors of mortality, and the coexistence of more conditions has addictive, but not synergistic, effect. The identification of patients at higher risk could promote a closer follow-up and more stringent measures of secondary prevention.

Abstract
Periprosthetic osteolysis is still one of the major limitations of prosthetic joints longevity. The process of this "silent" iatrogenic disease involves both mechanical and biological factors that initiate a local immune response in the periprosthetic tissue that eventually lead to implant loosening and failure. There are many causes of the primary aseptic loosening inside the periprosthetic microenvironment, but the most important elements are the wear debris and the cell-particle interactions. Together with implant position, micromotion, bearings, joint fluid pressure, and increased load on the joints drive the pathogenesis of the disease. This narrative review aims to summarise recent studies describing the biological and mechanical factors in the pathogenesis of osteolysis and some of the current pharmacological attempts to "rescue" a failing implant.

Abstract
BACKGROUND Epidemiological studies show an increasing trend of hospitalization for acute diverticulitis (AD), but data regarding the trend in hospitalization for complicated AD in Italy are scarce. The aim of this study was to analyze the Italian trend in hospitalization for complicated AD, from 2008 to 2015. METHODS Using the Italian Hospital Information System, we identified all patients with complicated colonic AD as a discharge diagnosis. Age- and sex-specific rates for AD as well as type of hospital admission (emergency/elective), type of complication (peritonitis, obstruction, bleeding, abscess, fistula, perforation, sepsis) and type of treatment (medical/surgical), were analyzed. RESULTS A total of 41,622 patients with a discharge diagnosis of complicated AD were identified. Over the study period the admission rate grew from 8.8 to 11.8 per 100,000 inhabitants. The hospitalization rate was highest for patients ≥ 70 years, but the increase in the admission rate was higher among patients aged ≤ 60 years. There were more males in the group < 60 years and more females in the group ≥ 60 years old. The rate of emergency admissions associated with surgery showed a significant mean annual increase (+ 3.9% per year) in the rate of emergency admissions associated with surgery, whereas elective admissions for surgery remained stable. Peritonitis was the most frequent complication (35.5%). The rate of surgery increased in AD complicated by peritonitis (+ 5.1% per year), abscess (+ 5.8% per year) and decreased for obstruction (- 1.8% per year). CONCLUSIONS From 2008 to 2015, we documented an increasing rate of hospitalization for complicated AD, especially for younger patients, with an increase in surgery for peritonitis and abscess. Further studies are needed to clearly assess the risk factors for complications and risk of surgery.

Abstract
AIM The optimal surgical treatment of splenic flexure neoplasm is still not well defined. Extended right hemicolectomy (ERH) and left colic resection (LCR) have been proposed but conclusive evidence concerning postoperative morbidity and oncological results is lacking. The aim of this study was to analyse the short-term outcomes after surgery for splenic flexure cancer with regard to surgical procedure and surgeon's specialty. METHODS This was a multicentre study on patients who underwent surgery for primary colon cancer of the splenic flexure. RESULTS From 2004 to 2015, 324 patients fulfilled the criteria for inclusion into the study; 270 (83.4%) had elective surgery while 54 (16.6%) had emergency resection: 158 (48.8%) underwent ERH and 166 (51.2%) LCR; 176 (54.3%) procedures were performed by colorectal surgeons, 148 (46.7%) by general surgeons. In the ERH group a significantly higher rate of emergency operations was carried out (P = 0.005). After elective surgery, no significant differences between ERH and LCR concerning 30-day mortality (3.3% vs 2.0%) and the need for reoperation (10.6% vs 7.4%) were found. Nodal harvesting was significantly higher in the ERH and colorectal surgeon groups in any clinical scenario. At multivariate analysis, age and smoking habit were predictive of the need for reoperation and major morbidity while the general surgeon group showed a higher risk of anastomotic failure (OR = 1.92; P = 0.168). CONCLUSION We analysed the largest series in literature of curative resections for splenic flexure tumours. The optimal procedure still remains debatable as ERH and LCR appear to achieve comparable short-term outcomes. Surgeon's specialty seems to positively affect patient's outcomes.

Abstract
Background The role of platinum-based neoadjuvant chemotherapy in triple-negative breast cancer (TNBC) patients is highly controversial and it is not endorsed by current guidelines. Our meta-analysis aimed to better elucidate its activity, efficacy and safety. Material and methods A systematic search of Medline, Web of Science and conferences proceedings up to 30 October 2017 was carried out to identify randomized controlled trials (RCTs) investigating platinum-based versus platinum-free neoadjuvant chemotherapy in TNBC patients. Using the fixed and random effects models, pooled odds ratios (ORs) and hazard ratios (HRs) with 95% confidence intervals (CI) were calculated for pathological complete response (pCR, defined as ypT0/is pN0), event-free survival (EFS), overall survival (OS) and grade 3 and 4 adverse events (AEs: neutropenia, anemia, thrombocytopenia and neuropathy). Results Nine RCTs (N = 2109) were included. Overall, platinum-based neoadjuvant chemotherapy significantly increased pCR rate from 37.0% to 52.1% (OR 1.96, 95% CI 1.46-2.62, P < 0.001). Platinum-based neoadjuvant chemotherapy remained significantly associated with increased pCR rate also after restricting the analysis to the three RCTs (N = 611) that used the same standard regimen in both groups of weekly paclitaxel (with or without carboplatin) followed by anthracycline and cyclophosphamide (OR 2.53, 95% CI 1.37-4.66, P = 0.003). Conversely, among the 96 BRCA-mutated patients included in two RCTs, the addition of carboplatin was not associated with significantly increased pCR rate (OR 1.17, 95% CI 0.51-2.67, P = 0.711). Two RCTs (N = 748) reported survival outcomes: no significant difference in EFS (HR 0.72, 95% CI 0.49-1.06, P = 0.094) and OS (HR 0.86, 95% CI 0.46-1.63, P = 0.651) was observed. A significant higher risk of grade 3 and 4 hematological AEs, with no increased risk of grade 3 and 4 neuropathy was observed with platinum-based neoadjuvant chemotherapy. Conclusion In TNBC patients, platinum-based neoadjuvant chemotherapy is associated with significantly increased pCR rates at the cost of worse hematological toxicities. Platinum-based neoadjuvant chemotherapy may be considered an option in TNBC patients. PROSPERO registration number CRD42018080042.

Abstract
Abstract
BACKGROUND
Extramedullary spine tumors represent two-thirds of all primary spine neoplasms. Approximately half of these are peripheral nerve sheath tumors, mainly neurofibromas and schwannomas and neurofibromatosis or schwannomatosis can be suspected. Given the rarity of this condition the clinical genetic and radiological features remains to be better define. The aim of this study was to characterize the clinical, radiologic presentation of patients with widespread spinal disease and to identify gene mutation.
MATERIAL AND METHODS
We selected patient with a at least: intradural extramedullary, or extradural intraspinal (tumor within the spinal canal), or extradural paraspinal (tumor at the neural foramenor extending outward into adjacent tissues) neoplasms and no other tumors such as meningiomas in the spine at spine MRI. Patients’ DNA were analyzed by Targeted NGS by means a custom gene panel including NF1, NF2, LZTR1, SMARCB1 genes.
RESULTS
63 patients were identified31 had few isolated tumors, involving spinal roots (Multiple Neurofibromas Few Spinal Root, MNFSR), 18 had bilateral neurofibromas involving all spinal roots. 14 had a single lesion; 10 cases were familiar and 53 sporadic. Genetic analysis showed NF1 gene mutations (in prevalence splicing or missense) in 49 cases LZTR1 mutations in 3 and in the others 11 no mutation or deletion was detected. Pain was the hallmark symptom in patients with LZTR1 mutations, while all familial cases all had NF1 diagnosis. About 50% of them had few cutaneous manifestations.
CONCLUSION
In patients with extramedullary spine tumors is important to look for signs of neurofibromatosis or schawannomatosis and if there are present genetic testing should be performed.

Abstract
BACKGROUND Epidemiological studies in Western countries have documented an increase of hospitalizations for acute diverticulitis (AD) but Italian evidence is scarce. The aim of the present study was to analyse the trend in hospitalization for AD, including in-hospital mortality, in Italy from 2008 to 2015. METHODS Through the Italian Hospital Information System of the National Health System, we identified diverticulitis of the colon as a discharge diagnosis. Age- and gender-specific rates of hospitalization for AD were assessed. RESULTS 174,436 hospitalizations were identified with an increasing rate in 2008-2015 from 39 to 48 per 100,000 inhabitants (p < 0.001). The rate of hospitalization was higher for women, but the increasing trend over time was even more pronounced among men (mean increase per year 3.9% and 2.1% among men and women, respectively) (p < 0.001). The increased rate of hospitalization was accounted for by patients less than 70 years old, especially those under 60. In contrast, the hospitalization rate for older patients (age ≥ 70 years) was higher but remained unchanged during the study period. The number of patients with one hospital admissions was significantly higher than the number of patients with at least two hospitalizations (p < 0.001) and both groups showed a significant and comparable increase year by year. The overall in-hospital mortality rate increased from 1.2 to 1.5% (p = 0.017). More specifically, the increase was observed in patients at their first hospitalization [from 1 to 1.4% (mean increase per year of 3%, p = 0.003)]. An increase in mortality was most evident among women (from 1.4 to 1.8% p = 0.025) and in older patients [age 70-79 years from 1.2 to 1.7% (p = 0.034), ≥ 80 years from 2.9 to 4% (p = 0.001)]. CONCLUSIONS In Italy, between 2008 and 2015, the rate of hospitalization for AD has been constantly increasing due to the hospitalization of younger individuals, especially men. There was a significant increase of in-hospital mortality especially among women, elderly and during the first hospitalization. These findings suggest the need for increased awareness and clinical skills in the management of this common condition.

Abstract
Eight factors were analyzed for prognostic significance in univariate analyses in a series of 76 women with stage IV ovarian carcinoma treated with combination chemotherapies including cisplatin or carboplatin. The clinical objective and pathologic complete response rates were 51.2% and 27.3%, respectively. Median overall survival and progression-free survival were 15 and 7 months, respectively. No variables reached statistical significance. Trends toward better survival were noted for grades 1 and 2 for the adriamycin-containing regimen. Using progression-free survival as an end point, significant prognostic factors included complete clinical or pathologic response. Our data confirm that the standard approach is unlikely to modify the clinical outcome of stage IV ovarian cancer. New treatment modalities including high-dose-intensity regimens and neo-adjuvant chemotherapy delivered before surgery could improve clinical results. Moreover, biologic characterization of ovarian tumors may provide information to design specifically targeted treatment.

Abstract
Nineteen consecutive patients with advanced or recurrent cervical cancer were treated with cisplatin 20 mg/m1 plus 5-fluorouracil 200 mg/m2 on days 1–5 every 3 weeks. Toxicity was acceptable and manageable, with most patients treated on an outpatient basis. The most important side effect was dose-cumulative neurotoxicity. In 18 evaluable patients a 61 % objective response rate (1 complete and 10 partial) was achieved. In recurrent disease the regimen was effective both in irradiated lesions and in non-irradiated ones. Two out of five patients not previously treated with radiotherapy and/or chemotherapy responded to the treatment but tumor regression was insufficient for the disease to be controlled radically by subsequent surgery or radiotherapy. The median duration of response was 11 months (3–23) and the actuarial survival rate after 36 months follow-up was 43.3 %.

Abstract
Eleven untreated patients with advanced ovarian cancer were studied for tolerance and response to combination treatment with fixed doses of adriamycin (45 mg/m2) and cyclophosphamide (600 mg/m2) + escalating doses of carboplatin. At the first dose level of carboplatin (200 mg/m2), toxicity was acceptable. With carboplatin at 300 mg/m2, severe hematologic toxicity was observed. The dose-limiting toxicity was leukopenia. Although carboplatin was administered without any hydration, no patient experienced renal toxicity. Eight objective responses were observed in 9 clinically evaluable patients. At second look surgery, 3 complete responses and 4 partial responses were documented. Polychemotherapy with JAC (carboplatin, 200 mg/m2, adriamycin, 45 mg/m2, and cyclophosphamide, 600 mg/m2) is administrable with acceptable toxicity.

Preventing Fusion Mass Shift Avoids Postoperative Distal Curve Adding-on in Adolescent Idiopathic Scoliosis. Clin Orthop Relat Res 2017; 475:1448-1460.

Abstract
BACKGROUND Surgery for adolescent idiopathic scoliosis (AIS) is only complete after achieving fusion to maintain the correction obtained intraoperatively. The instrumented or fused segments can be referred to as the "fusion mass". In patients with AIS, the ideal fusion mass strategy has been established based on fulcrum-bending radiographs for main thoracic curves. Ideally, the fusion mass should achieve parallel endplates of the upper and lower instrumented vertebra and correct any "shift" for truncal balance. Distal adding-on is an important element to consider in AIS surgery. This phenomenon represents a progressive increase in the number of vertebrae included distally in the primary curvature and it should be avoided as it is associated with unsatisfactory cosmesis and an increased risk of revision surgery. However, it remains unknown whether any fusion mass shift, or shift in the fusion mass or instrumented segments, affects global spinal balance and distal adding-on after curve correction surgery in patients with AIS. QUESTIONS/PURPOSES (1) To investigate the relationship among postoperative fusion mass shift, global balance, and distal adding-on phenomenon in patients with AIS; and (2) to identify a cutoff value of fusion mass shift that will lead to distal adding-on. METHODS This was a retrospective study of patients with AIS from a single institution. Between 2006 and 2011 we performed 69 selective thoracic fusions for patients with main thoracic AIS. All patients were evaluated preoperatively and at 2 years postoperatively. The Cobb angle between the cranial and caudal endplates of the fusion mass and the coronal shift between them, which was defined as "fusion mass shift", were measured. Patients with a fusion mass Cobb angle greater than 20° were excluded to specifically determine the effect of fusion mass shift on distal adding-on phenomenon. Fusion mass shift was empirically set as 20 mm for analysis. Therefore, of the 69 patients who underwent selective thoracic fusion, only 52 with a fusion mass Cobb angle of 20° or less were recruited for study. We defined patients with a fusion mass shift of 20 mm or less as the balanced group and those with a fusion mass shift greater than 20 mm as the unbalanced group. A receiver operating characteristic (ROC) curve was used to determine the cutoff point of fusion mass shift for adding-on. RESULTS Of the 52 patients studied, fusion mass shift (> 20 mm) was noted in 11 (21%), and six of those patients had distal adding-on at final followup. Although global spinal balance did not differ significantly between patients with or without fusion mass shift, the occurrence of adding-on phenomenon was significantly higher in the unbalanced group (55% (six of 11 patients), odds ratio [OR], 8.6; 95% CI, 2-39; p < 0.002) than the balanced group (12% [five of 41 patients]). Based on the ROC curve analysis, a fusion mass shift more than 18 mm was observed as the cutoff point for distal adding-on phenomenon (area under the curve, 0.70; 95% CI, 0.5-0.9; likelihood ratio, 5.0; sensitivity, 0.64; specificity, 0.73; positive predictive value, 39% [seven of 18 patients]; negative predictive value, 88% [30 of 34 patients]; OR, 4.8; 95% CI, 1-20; p = 0.02). CONCLUSIONS Our study illustrates the substantial utility of the fulcrum-bending radiograph in determining fusion levels that can avoid fusion mass shift; thereby, underlining its importance in designing personalized surgical strategies for patients with scoliosis. Preoperatively, determining fusion levels by fulcrum-bending radiographs to avoid residual fusion mass shift is imperative. Intraoperatively, any fusion mass shift should be corrected to avoid distal adding-on, reoperation, and elevated healthcare costs. LEVEL OF EVIDENCE Level II, prognostic study.

[PMID: 27713009 DOI: 10.1016/j.jos.2016.09.008] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/25/2016] [Revised: 09/09/2016] [Accepted: 09/14/2016] [Indexed: 11/28/2022]
Abstract
PURPOSE Patients with pre-existing cervical spinal canal stenosis (CSCS) may have minimal or no symptoms. However, performing preventive decompression is controversial as the incidence of CSCS leading to severe cord injury is unknown. Hence, this study aims to revisit the threshold for surgery in "silent" CSCS by reviewing the neurologic outcomes of patients with undiagnosed CSCS who sustained a cervical spinal cord injury (CSCI). METHODS Two groups of subjects were recruited for analysis. Firstly, patients with trauma-induced CSCI without fracture or dislocation were included. Pre-existing CSCS was diagnosed by MRI measurements. The second group consisted of asymptomatic subjects recruited from the general population who also had MRIs performed. Canal sizes were compared between this control group and the patient group. Within the patient group, neurological assessments and outcomes by Frankel classification were performed in patients treated surgically or conservatively. RESULTS 32 patients with CSCS were recruited. The mean spinal canal sagittal diameter (disc-level) of all CSCS cases was 5.3 ± 1.4 mm (1.3-8.2). In comparison, the diameter was 10.5 ± 1.7 mm (6.6-14.6) in the 47 asymptomatic individuals recruited from the general population. Decompression was performed in 17 patients and conservative treatment in 15. Mean follow-up was 19.3 ± 17.0 months (6-84). At the final follow-up, 3 patients (9.3%) returned to their pre-injury Frankel grade, whereas 26 patients (83.3%) lost one or more neurological grade. Three patients (9.3%) died. CONCLUSIONS Majority of patients with "silent" CSCS who sustained cervical cord injuries did not return to their pre-injury neurological status. All of these subjects have pre-existing canal stenosis hence the risk of cord injury. Given the poor neurological outcome of CSCS, a lower threshold for surgery could be indicated to avoid these disastrous injuries. However, before making any conclusive recommendation we must first identify the prevalence of "silent" CSCS in the general population and the risk of developing spinal cord injury with more prospective population-based studies.

Abstract
BACKGROUND Allergic rhinitis (AR) is characterized by an IgE-mediated reaction. Aging usually induces a progressive decline of immune system function. There is common belief that both allergic symptoms severity and serum IgE production decline during aging. OBJECTIVE This study aimed to evaluate the possible impact of age on: i) serum allergen-specific IgE levels in a large sample of subjects, and ii) AR symptom severity in a group of mono-allergic patients. METHODS Serum allergen-specific IgE to birch, Bet v 1, Parietaria, and Dermatophagoides pteronyssinus were measured by immunofluorometric assay (IFMA) in a sample of 8098 subjects. AR symptom severity was assessed by visual analogue scale (VAS) in a sub-group of 531 mono-allergic patients. RESULTS The analysis of variance showed that IgE to Bet v 1, birch, and Dermatophagoides pteronyssinus significantly decreased considering the age, whereas IgE to Parietaria did not significantly decline in respect of the age. Considering the global sample of mono-allergic patients, elderly subjects (over 65 years old) tended to have lower IgE levels, but had significantly lower VAS rating, and significantly less sensitizations than adult subjects (18-65 years old). In both adult and elderly patients VAS strongly correlated with IgE values. CONCLUSIONS Allergen-specific IgE levels tend to reduce with aging, but with differences between types of allergy. The IgE decrease is usually associated with reduced AR symptom severity. Elderly AR patients seem to have a different phenotype/endotype in comparison with adult AR ones, characterized by milder symptoms, lower IgE production, and less sensitizations. However, a close positive relationship between IgE values and VAS scores is shared by both adult and elderly AR patients, confirming the close link between allergy and symptoms that persists also in the elderly.

Abstract
The possible toxic effects of intra-articular tranexamic acid (TA) are still debated. The aim of this study was to evaluate TA effects on human cartilage fragments and synovial biopsies. Explant culture of minced articular cartilage underwent prolonged TA exposure. Histological analysis, immunofluorescence and colorimetric assay for quantification of s-GAG and DNA were performed at the end term. Synoviocytes were cultured for 48h in presence of TA. Light microscopy and flow cytometry analysis were performed at the end of the exposure to TA and one week after the treatment. TA exposure did not influence i) the chondrocyte outgrowth and migration, ii) the expression of chondrogenic and proliferative markers and iii) the s-GAG/DNA ratio. TA treatment did not affect synoviocytes’ morphology and treated cells were phenotypically similar to control cells. This study demonstrated that TA does not negatively affect chondrocytes and synoviocytes cultured in vitro. Thus, our findings may be clinically relevant in order to validate the intra-articular TA administration during orthopedic procedures.

Abstract
This study evaluates effects of good burning practice and correct installation and management of wood heaters on indoor air pollution in an Italian rural area. The same study attests the role of education in mitigating wood smoke pollution. In August 2007 and winters of 2007 and 2008, in a little mountain village of Liguria Apennines (Italy), indoor and outdoor benzene, toluene, ethylbenzene, and xylene (BTEX) concentrations were measured in nine wood-heated houses. During the first sampling, several mistakes in heating plant installations and management were found in all houses. Indoor BTEX concentrations increased during use of wood burning. Low toluene/benzene ratios were in agreement with wood smoke as main indoor and outdoor pollution source. Other BTEX sources were identified as the indoor use ofsolvents andpaints and incense burning. Results obtained during 2007 were presented and discussed with homeowners. Following this preventive intervention, in the second winter sampling all indoor BTEX concentrations decreased, in spite of the colder outdoor air temperatures. Information provided to families has induced the adoption of effective good practices in stoves and fire management. These results highlight the importance ofeducation, supported by reliable data on air pollution, as an effective method to reduce wood smoke exposures.

Abstract
The objective of this study was to evaluate the efficacy of the endothelin receptor antagonist, bosentan, in patients with Raynaud's phenomenon secondary to systemic sclerosis never treated with prostanoids and without digital ulcers. The study design is a preliminary, prospective open label trial. The patients recruited took one 62.5 mg dose of bosentan twice daily for 4 weeks, followed by 125 mg twice daily for 24 weeks. Of the 10 patients recruited, all completed the study. The reduction in Raynaud's phenomenon attacks at week 24 from the baseline was statistically significant (Δ-1.3, P=0.0126). The Raynaud's condition score showed a statistically significant improvement (Δ-1.4, P=0.0279), as did the visual analog pain scale (Δ-1.5, P=0.0016) at the 24th week. Bosentan appears to be effective and may be a valid alternative for the treatment of severe secondary Raynaud's phenomenon for patients where prostanoids therapy is contraindicated or refused.

Human cartilage fragments in a composite scaffold for single-stage cartilage repair: an in vitro study of the chondrocyte migration and the influence of TGF-β1 and G-CSF. Knee Surg Sports Traumatol Arthrosc 2013; 21:1819-33.

Abstract
PURPOSE Minced chondral fragments are becoming popular as a source of cells for cartilage repair, as a growing interest is developing towards one-stage procedures to treat cartilage lesions. The purpose of this study is to (A) compare cell outgrowth from cartilage fragments of adult and young donors using two different types of scaffolds and (B) evaluate the influence of transforming-growth-factor-β1 (TGF-β1) and granulocyte colony-stimulating factor (G-CSF) on chondrocyte behaviour. METHODS In part (A) cartilage fragments from adult and young donors were either loaded onto an HA-derivative injectable paste scaffold or onto an HA-derivative membrane scaffold. Construct sections were then examined for cell counting after 1, 2 and 3 months. In part (B) only membrane scaffolds were prepared using cartilage fragments from young donors. Constructs were cultured either in standard growth medium or in the presence of specific growth factors, such as TGF-β1 or G-CSF or TGF-β1 + G-CSF. After 1 month, construct sections were examined for cell counting. Expression of chondrocyte markers (SOX9, CD151, CD49c) and proliferative markers (β-catenin, PCNA) was assessed using immunofluorescence techniques, both in unstimulated construct sections and in cells from unstimulated and stimulated construct cultures. RESULTS Part (A): histological analysis showed age-dependent and time-dependent chondrocyte migration. A significant difference (p < 0.05) was observed between young and older donors at the same time point. No difference was detected between the two types of scaffolds within the same group at the same time point. Part (B): after 1 month, the number of migrating cells/area significantly increased due to exposure to TGF-β1 and/or G-CSF (p < 0.05). Immunofluorescence revealed that outgrowing cells from unstimulated scaffold sections were positive for SOX9, CD151, CD49c and G-CSF receptor. Immunofluorescence of cells from construct cultures showed an increase in β-catenin in all stimulated groups and an increased PCNA expression in G-CSF-exposed cultures (p < 0.05). CONCLUSION Outgrowing cells may represent a subset of chondrocytes undergoing a phenotypic shift towards a proliferative state. TGF-β1, and to a greater extent G-CSF, may accelerate this outgrowth. The clinical relevance of this study may involve a potential future clinical application of scaffolds preloaded with growth factors as an additional coating for chondral fragments. Indeed, a controlled delivery of G-CSF, widely employed in various clinical settings, might improve the repair process driven by minced human cartilage fragments during one-stage cartilage repair.
