Chronic therapy in gastrointestinal stromal tumours (GISTs): the big gap between theory and practice

Physicians' Online Writing Language Style and Patient Satisfaction: The Mediator of Depth of Physician-Patient Interactions

Online health counseling (OHC) is increasingly important in modern healthcare. This development has attracted considerable attention from researchers. However, the reality of the lack of physician-patient communication and dissatisfaction with online health services remains prevalent, and more research is needed to raise awareness about important issues related to OHC services, especially in terms of patient satisfaction and depth of interaction (i.e., the product of the number of interactions and the relevance of the content). This study constructs an empirical model to explore the relationship between physicians' online writing language style (inclusive language and emojis), depth of physician-patient interactions, and patient satisfaction. The study obtained 5064 online health counseling records from 337 pediatricians and analyzed them using text mining and empirical methods. The results showed that physicians' inclusive language (β = 0.3198, p < 0.05) and emojis (β = 0.6059, p < 0.01) had a positive impact on patient satisfaction. In addition, the depth of the physician-patient interaction partially mediated this effect. This study promotes a better understanding of the mechanisms of physician-patient interactions in online settings and has important implications for how online physicians and platforms can better provide online healthcare services.

Primary Localized Gastrointestinal Stromal Tumors: Medication Adherence and Prognosis According to Gender

OBJECTIVE

Gender is associated with medication adherence for imatinib, but whether it is related to the prognosis of primary localized gastrointestinal stromal tumors (GISTs) is unclear. The goal of this study was to clarify the relationship between gender and prognosis in GIST patients, with differences in medication adherence considered.

METHODS

The data of 320 GIST patients were retrospectively collected from the First Affiliated Hospital of Chongqing Medical University. Survival analysis was performed using the Kaplan-Meier method (Log rank test) and the risk factors of recurrence were determined using Cox multivariate analysis. Medication adherence-stratified analyses were performed to control for confounding factors.

RESULTS

Kaplan-Meier analysis revealed that among patients who received postoperative adjuvant imatinib therapy, men had a higher recurrence rate than women (P<0.01). Pearson's chi-square test revealed better medication adherence in women than in men (P<0.01). Cox regression analysis revealed that gender was not an independent risk factor for recurrence-free survival (RFS; P=0.25), but medication adherence was (P<0.01). Among GIST patients with a medication possession ratio (MPR) of less than 90%, 62.86% of male patients took imatinib irregularly or not at all due to limited understanding of the disease, whereas 55.74% of female patients' took imatinib irregularly because they could not tolerate adverse drug reactions.

CONCLUSION

Adherence was poorer in male than in female patients, which might explain the worse prognoses of the former among patients who received adjuvant treatment with imatinib. The gender difference in the degree of adherence should be considered in postoperative pharmacotherapy for patients with primary localized GISTs.

Successful treatment with personalized dosage of imatinib in elderly patients with gastrointestinal stromal tumors

Imatinib is the standard first-line therapy for metastatic gastrointestinal stromal tumors. It has markedly improved the prognosis and outcome of patients affected by gastrointestinal stromal tumors, especially in the case of exon 11 KIT mutations. Imatinib-associated adverse events are generally mild to moderate; however, in clinical practice, intolerance caused by chronic toxicities frequently leads to breaks in treatment. This is particularly true in elderly patients in whom age, decline in drug metabolism, and polypharmacy, with a possible drug-drug interaction, may influence the tolerability of imatinib. In the present article, we report our extensive experience with the management of imatinib therapy in a 'real' population, in particular in very elderly patients, discussing whether the use of personalized imatinib dosage could be a safe and advantageous option, enabling continuous administration, thus ensuring effective treatment. Only a few case reports in the literature provide data on outcome with low tailored dosage of imatinib and none of them has been carried out on a Western population. Here, we report four cases treated with low imatinib dosage as a safe and useful option enabling continued treatment with imatinib, improving tolerance, and maintaining good and lasting disease control.

Alternative schedules or integration strategies to maximise treatment duration with sunitinib in patients with gastrointestinal stromal tumours

Gastrointestinal stromal tumours (GISTs) are the most common mesenchymal tumour of the gastrointestinal tract. The advent of targeted kinase-inhibitors has revolutionised treatment strategies and clinical outcomes for patients with advanced GIST. In the majority of countries, sunitinib is the only approved second-line treatment option for advanced GIST patients, who are resistant or intolerant to imatinib. However, sunitinib is associated with various adverse events, which often result in a reduction of the dosage, and interruption or suspension of therapy. Effective therapy management is essential to obtain the maximum clinical benefit, and includes adequate side effect management as well as optimization of dosing and treatment duration. In the current study, examples of maximization of treatment with sunitinib are presented, describing three clinical cases in which therapy with sunitinib was continued via the adoption of alternative reduced schedules or an additional loco-regional treatment, in order to manage toxicities or overcome progressive disease.

Chronic myeloid leukemia in adolescents and young adults: patient characteristics, outcomes and review of the literature

Over the past two decades, many improvements have been made in the management of patients with leukemia. Research in this field most often focuses on the youngest and oldest patient age groups. However, the population of patients in between those age groups has received relatively little attention with few studies specifically focusing on them. This important 'age gap' has demonstrated a unique, difficult-to-treat group of patients known as adolescents and young adults, or AYAs. Variably defined in the literature as patients from late teenage years to the age of up to 40 years, the AYA group of patients represents a vulnerable subset of patients now identified to require its own focus, development of therapeutic strategies and parallel emphasis on special support systems involving multidisciplinary psychosocial care. Despite the great advancements that have been realized for patients with chronic myeloid leukemia (CML), the AYA group has seldom been the focus of specific reports and studies, and the outcome appears to lag behind the general population. This review focuses on this subset of AYA patients with CML and summarizes the available data and recent developments, challenges and treatment options for this group of patients.
