Background: Surgery, the treatment of choice for parotid pleomorphic adenoma (PA), is associated with facial nerve palsy and decreased quality of life. Re-operation for PA recurrence (rPA) significantly increases these risks and constitutes a dilemma for both patient and surgeon. Factors influencing the success of re-operation, as well as the self-reported satisfaction of both sides, have yet to be addressed in the literature. This study aims to improve upon the decision-making schedule in PA re-operations, based on patient expectations, imaging, and concordance with the first operative report (FOpR).

Methods: Seventy-two rPAs treated in a single tertiary center were collected and analyzed. The FOpRs and pre-operative imaging were divided according to defined criteria into accurate and non-accurate categories. The re-operative field and course were categorized as anticipated or unanticipated. The re-operation was categorized as satisfactory or unsatisfactory for both the patient and the surgeon.

Results: The accuracy of FOpRs and pre-operative imaging was 36.1% and 69.4%, respectively. Re-operative courses were: 36.1% anticipated and 63.9% unanticipated. The most frequently omitted data were: presence of satellite tumors (9.7%), and amount of removed parenchyma (9.7%). Variables that most commonly affected FOpR non-accuracy were: tumor size (Chi2(1)=59.92; p < 0.001) and capsule condition (Chi2(1)=29.11; p < 0.001). There was no significant relationship between FOpR accuracy and re-operative course (Chi2(1)=1.14; p = 0.286), patient satisfaction (Chi2(1)=1.94; p = 0.164) or surgeon satisfaction (Chi2(1)=0.04; p = 0.837). Pre-operative imaging (Chi2(1)=36.73; p < 0.001) had the greatest impact on surgeon satisfaction.

Conclusion: Accurate pre-operative imaging impacted surgeon satisfaction. The impact of the FOpR on re-operation technicalities and patient satisfaction was minor. Imaging precision should be improved to streamline the decision-making process of PA re-operation. This article proposes suggestions for a future decision-making algorithm as a starting point for a prospective study.Key messagesAccurate pre-operative imaging impacts both surgeon and patient satisfaction.There is no significant relationship between the accuracy of the first operative report and surgeon and patient satisfaction.There is a statistically significant relationship between patient and surgeon satisfaction.

Objective: This population-based study aimed to determine the hesitancy and willingness to pay (WTP) for the booster dose of a coronavirus disease (COVID-19) vaccine among patients with cancer in Taizhou, China.

Patients and methods: A self-administered online questionnaire was administered to patients with cancer in Taizhou, China. The chi-square test, binary logistic regression model were used to evaluate the WTP for the booster dose of a COVID-19 vaccine. The minimum sample size was 218, determined by G*Power software (latest ver. 3.1.9.7). A total of 354 patients received the survey, and 256 (72.3%) patients responded.

Results: Overall, 69.9% (179/256) of respondents were willing to pay for the booster dose, and 78.8% (141/179) of these patients were willing to pay 1-99 CNY. Furthermore, 50.4% (129/256) of respondents were hesitant to receive a COVID-19 vaccine. Being unhesitant was significantly associated with WTP for the booster dose (aOR: 3.040; 95% CI: 1.669-5.540).

Conclusion: Hesitant patients with cancer had a lower WTP for the booster dose against COVID-19 than non-hesitant participants. These results imply that further health education programmes are essential to decrease the hesitancy of patients with cancer and enhance booster dose vaccination rates for public health improvements.KEY MESSAGESOur research showed that 70% of patients with cancer are willing to pay for the booster dose of the COVID-19 vaccine, and most are willing to pay less than 100 CNY, and this result reflects the economic value and affordability of the third dose of vaccination.COVID-19 vaccine-hesitant patients with cancer had a lower willingness to pay for a booster dose against COVID-19 than non-hesitant participants and few patients are still unwilling to pay among patients do not hesitate to receive the third dose.Therefore, promoting willingness to pay among oncology patients and addressing vaccine hesitancy remains key.

Objective: The aim of this study was to define the clinical, histopathologic, and prognostic features associated with simultaneous positivity for anti-dsDNA, -nucleosome, and -histone antibodies (3-pos) in Korean patients with biopsy-proven lupus nephritis (LN).

Methods: The 102 patients included in the study had undergone kidney biopsy prior to the start of induction treatment, were treated with immunosuppressives, and followed-up for >12 months.

Results: In total, 44 (43.1%) of the 102 LN patients were 3-pos. Patients with 3-pos had a higher SLEDAI-2K score (p = .002), lower lymphocyte count (p = .004), and higher rates of proteinuria > 3.5 g/24 h (p = .039) and positivity for urinary sediments (p = .005) at the time of renal biopsy than non-3-pos patients. 3-pos patients had a more proliferative form of LN (p = .045) in the renal histopathologic findings, and as co-positivity gradually increased from 0 to 3, the total activity score in the renal biopsy findings increased significantly (p = .033). In addition, 3-pos patients had a more rapid eGFR decline than non-3-pos patients after a follow-up of 83.2 months (p = .016).

Conclusions: Our findings suggest that 3-pos is related to severe LN and that 3-pos patients are more likely to experience a rapid decline of renal function than non-3-pos patients.KEY MESSAGEPatients with co-positivity for anti-dsDNA, -nucleosome, and -histone antibodies (3-pos) had higher disease activity and a worse renal histopathology than those without co-positivity.3-pos patients had a more rapid decline of renal function than non-3-pos patients.

Background/aims: Colorectal cancer is the third leading cause of death in patients with cancers in America. Monensin has represented anti-cancer effect on various human cancer cells. We seek to investigate the effect of monensin on proliferation of human colorectal cancer cells and explore whether IGF1R signaling pathway is involved in anti-cancer mechanism of monensin.

Methods: Cell proliferation and migration were assessed by crystal violet staining and cell wounding assay respectively. Cell apoptosis was analyzed by Hoechst 33258 staining and flow cytometry. Cell cycle progression was detected with the use of flow cytometry. Cancer-associated pathways were assessed with the use of pathway-specific reporters. Gene expression was detected by touchdown-quantitative real-time PCR. Inhibition of IGF1R was tested by immunofluorescence staining. Inhibition of IGF1R signaling was accomplished by adenovirus-mediated expression of IGF1.

Results: We found that monensin not only effectively inhibited cell proliferation, cell migration as well as cell cycle progression, but also induced apoptosis and G1 arrest in human colorectal cancer cells. Monensin was shown to target multiple cancer-related signaling pathways such as Elk1, AP1, as well as Myc/max, and suppressed IGF1R expression via increasing IGF1 in colorectal cancer cells.

Conclusion: Monensin could suppressed IGF1R expression via increasing IGF1 in colorectal cancer cells. It has the potential to be repurposed as an anti-colorectal cancer agent, but further studies are still required to investigate the detailed mechanisms of monensin underlying its anti-cancer motion.Key MessagesMonensin inhibits the cell proliferation and the migration, induces apoptosis and inhibits cell cycle progression in human colorectal cancer cells.Monensin may exert anti-cancer activity by targeting multiple signaling pathways, including the IGF1R signaling pathway.Monensin has the potential to be repurposed as an anti-colorectal cancer agent.

Background: Hepatocellular carcinoma lacks ideal diagnostic biomarkers. There is a lack of scientific evaluation of relevant promising biomarkers as well. Therefore this study reanalyzes the related studies of 11 blood biomarkers of HCC, and compares the diagnostic value of these biomarkers for HCC systematically.

Methods: The relevant literatures on the diagnostic value in HCC of 11 blood indexes in recent 5 years were searched in PubMed, Embase, and Cochrane libraries. Data were extracted and analyzed.

Results: Finally, 83 literature studies were brought into meta-analysis. The pooled sensitivity and specificity of AFP were 0.61 and 0.87, respectively. The AUC of AFP were 0.78. The AUC and sum of sensitivity and specificity of the combination of AFP and other biomarkers were all significantly higher than that of AFP, including AFP + AFP-L3 + DCP, AFP + DCP, AFP/DCP, AFP + GPC3. Among other biomarkers, the AUC and sum of sensitivity and specificity of biomarkers including DCP, GPC3, GP73, Hsp90alpha, midkine, and OPN were significantly higher than that of AFP. In this study, GP73 had the highest sum of sensitivity and specificity (1.78) and AUC (0.95).

Conclusions: The pooled sensitivity and specificity of AFP were 0.61 and 0.87, respectively. The AUC of AFP were 0.78. The combination of AFP and other biomarkers improved the diagnostic efficiency. The diagnostic value of biomarkers including DCP, GPC3, GP73, Hsp90alpha, midkine, and OPN was higher than that of AFP.

Background: We discovered that vitiligo was associated with sexual dysfunction in clinical diagnosis and treatment; however, no further analysis had been performed due to a lack of data.

Objective: This study aimed to clarify the relationship between vitiligo and sexual dysfunction.

Methods: We searched six databases (PubMed, Embase, Cochrane, China National Knowledge Infrastructure, China Science and Technology Journal, and Wanfang Data Knowledge Service Platform) for nearly 40 years.

Results: According to the search strategy, 91 relevant studies were retrieved, of which 4 were included in the analysis. The Arizona Sexual Experience Scale (ASEX) score (mean difference [MD] 4.96, 95% confidence interval [CI] 2.78-7.13, p < 0.00001) was higher in the vitiligo group than in the control group. The Arabic version of the Female Sexual Function Index (AVFSFI) score (mean difference [MD] - 3.40, 95% confidence interval [CI] - 5.49 to -1.31, p = 0.001) was lower in the vitiligo group than in the control group.

Conclusions: Patients with vitiligo were found to be at greater risk of sexual dysfunction. Moreover, the association between vitiligo and sexual dysfunction was stronger in women than in men.Key MessagesPatients with vitiligo were found to be at greater risk of sexual dysfunction.The association between vitiligo and sexual dysfunction was stronger in women than in men.

Metastases to the central nervous system (CNS) in patients with non-small cell lung cancer constitute an extremely difficult clinical problem, and their occurrence is associated with a poor prognosis. Due to the existence of the blood-brain barrier (BBB) and the action of proteins responsible for the transport of drugs, e.g. P-glycoprotein (P-gp), the penetration of drugs into the CNS is insufficient. Until recently, the only method of CNS metastases treatment was radiotherapy and neurosurgery. The advancement of molecular biology allowed discover targets for molecularly targeted therapies. One of targets is abnormal anaplastic lymphoma kinase, which results from the rearrangement of the ALK gene in patients with non-small cell lung cancer (NSCLC). ALK rearrangement occurs in only about 4.5% of NSCLC patients, but its presence favors brain metastases. The ALK inhibitors (ALKi) were modified to obtain molecules with high ability to penetrate into the CNS. This was achieved by modifying the structure of individual molecules, which became, inter alia, less substrates for P-gp. These modifications caused that less than 10% of patients experience progression in CNS during new ALK inhibitors treatment. This review summarizes the knowledge about the action of BBB, the pharmacodynamics and pharmacokinetics of ALKi, with particular emphasis on their ability to penetrate the CNS and the intracranial activity of individual drugs from different generations of ALK inhibitors.
