A Higher Angiogenin Expression is Associated With a Nonnuclear Maspin Location in Laryngeal Carcinoma

Objectives

In numerous malignancies, angiogenin (ANG) and Maspin are important proangiogenic and antiangiogenic regulators, respectively. The aim of this study was to identify potential relationships between the biological roles of these two proteins in laryngeal squamous cell carcinoma (LSCC).

Methods

Immunohistochemical staining for ANG and Maspin was performed on specimens from 76 consecutive LSCC patients treated with surgery alone, considering the subcellular pattern of Maspin expression. Univariate and multivariate statistical models were used for prognostic purposes.

Results

On univariate analysis, a different level of ANG expression was seen for patients stratified by subcellular Maspin expression pattern: the mean ANG expression was higher in cases with a nonnuclear MASPIN expression than in those with a nuclear pattern (P=0.002). Disease-free survival (DFS; in months) differed significantly when patients were stratified by N stage (P=0.01). Patients whose Maspin expression was nonnuclear (i.e., it was cytoplasmic or there was none) had a significantly higher recurrence rate (P<0.001), and shorter DFS (P=0.01) than those with a nuclear Maspin pattern. The mean ANG expression was significantly higher in cases with loco-regional recurrent disease (P=0.007); and patients with an ANG expression ≥5.0% had a significantly shorter DFS than those with an ANG expression <5.0% (P=0.007). On multivariate analysis, ANG expression ≥5.0% was a significant, independent, negative prognostic factor in terms of DFS (P=0.041).

Conclusion

Our results support the hypothesis that a higher ANG expression is associated with a nonnuclear Maspin expression pattern in patients with LSCC. Further studies are needed to clarify the relationship between the ANG and Maspin pathways, and their potential diagnostic and therapeutic role in LSCC.     

Squamous-cell carcinoma developing within anal lichen planus

AIM: We present a case of squamous-cell carcinoma developing within perianal lichen planus. This is a chronic or recurrent cutaneous and/or mucosal dermatosis affecting less than 1 percent of the population. Neoplastic degeneration of cutaneous lichen planus is rare; only one case of squamous-cell carcinoma developing within perianal lichen planus has been described up until now in the international literature. CASE REPORT: Our case involved a 68-year-old woman with chronic, long-term lichen planus spreading all over the vulva and perianal region and the mucosa of the anal canal, where squamous-cell carcinoma developed within the perianal lichen planus. Treatment consisted of wide, circular excision of the perianal skin and mucosectomy of the anal canal up to as far as 1 cm above the dentate line. Reconstruction was performed by means of two V-Y bilateral subcutaneous flaps. CONCLUSION: Wide excision was performed not only to remove the squamous-cell carcinoma but also the lichen planus to prevent recurrence of metachronous or synchronous squamous-cell carcinoma. Follow-up at one year after surgery showed no local recurrence of either lichen planus or squamous-cell carcinoma, which suggests that surgical removal should be the therapy of choice for long-term, chronic perianal lichen planus that has proved to be resistant to medical therapy.     

Usefulness of the PARIS Score to Evaluate the Ischemic-hemorrhagic Net Benefit With Ticagrelor and Prasugrel After an Acute Coronary Syndrome

Introduction and objectives

The PARIS score allows combined stratification of ischemic and hemorrhagic risk in patients with ischemic heart disease treated with coronary stenting and dual antiplatelet therapy (DAPT). Its usefulness in patients with acute coronary syndrome (ACS) treated with ticagrelor or prasugrel is unknown. We investigated this issue in an international registry.

Prognostic relevance of microsatellite instability in pT3N0M0 colon cancer: a population-based study

Although surgery alone represents a curative approach for patients with pT3N0M0 colon cancer, about 15–20 % of these patients develop a relapse of disease. Microsatellite instability (MSI) is one of the most important molecular markers in colorectal cancer. The aim of this study was to investigate the prognostic relevance of MSI in all pT3N0M0 tumors recorded in the Cancer Registry of the Province of Modena—(Northern Italy) within the 2002–2006 period in patients who showed a relapse of disease during the 5-year period of follow-up (59 cases). They were compared to 59 controls similar in clinical and pathological features but with good prognosis. None of the subjects received adjuvant chemotherapy. MSI status was tested using BAT25, BAT26, NR24, and CAT25 fluorescent-labeled mononucleotide markers. The overall prevalence of MSI was 12.7 % (15 of 118 cases). MSI was detected mainly in mucinous adenocarcinoma (p < 0.003), in high-grade tumors (p < 0.008), in right-sided neoplasms (p < 0.005), and in patients with a better prognosis, though the difference was not statistically significant (11/59 patients ?18.6 % vs 4/59 patients ?6.7 %; OR 0.36 CI 95 % 0.11–1.15; p = 0.08). However, in multivariate analysis, MSI status becomes the strongest independent factor associated with relapse (OR 0.21, CI 95 % 0.06–0.81; p = 0.023), together with mucinous histological type (OR 0.40, CI 90 % 0.18–0.92). MSI is a relevant prognostic factor in stage pT3N0M0 colon cancer suitable to discriminate those patients with a high risk of relapse.     

Cardiovascular impact of testosterone therapy for hypogonadism

Introduction: Since 2010 some evidence supporting the possible increased cardiovascular (CV) risk related to testosterone treatment (TTh) has created much debate in the scientific community. Based on these results, the US Food and Drug Administration agency has questioned TTh for aging men recognizing its value only for classical hypogonadism due to genetic or organic causes. To better clarify this topic, we scrutinized and summarized, also by using meta-analytic methods, the data generated during the last 7 years, as derived from the analysis of randomized controlled trials (RCTs) on TTh and CV risk.

Areas covered: Analysis included 31 RCTs published between 2010 and 2018. Retrieved trials included 2675 and 2308 patients in TTh and placebo groups, respectively. The analysis documented that TTh was not associated with an increased CV mortality or morbidity either when overall or major adverse CV events were considered.

Expert commentary: Despite present evidence it is important to recognize that the duration of the available trials is short (lower that 3 years) limiting final conclusions on this topic. In particular, the available information on possible long-term effects of TTh on CV risk is limited. Long-term safety studies are advisable to better clarify these points.     

HYPNOTIZABILITY AND PAIN MODULATION: A Body–Mind Perspective

The study investigated whether the cardiac activity and cognitive–emotional traits sustained by the behavioral inhibition/activation system (BIS/BAS) may contribute to hypnotizability-related pain modulation. Nociceptive stimulation (cold-pressor test) was administered to healthy participants with high (highs) and low (lows) hypnotizability in the presence and absence of suggestions for analgesia. Results showed that heart rate increased abruptly at the beginning of nociceptive stimulation in all participants. Then, only in highs heart rate decreased for the entire duration of hand immersion. During stimulation with suggestions of analgesia, pain threshold negatively correlated with heart rate. BIS/BAS activity partially accounted for the observed hypnotizability-related differences in the relation between cardiac interoception and pain experience.
