Abstract
The effectiveness of psychological interventions (PI) for malignant diseases is controversial. We aimed to investigate the effect of PI on survival and quality of life (QoL) in patients with cancer. We performed a systematic search of MEDLINE, Cochrane, and Embase databases to identify randomized controlled trials comparing PI to standard care (PROSPERO registration number CRD42021282327). Outcomes were overall survival (OS), recurrence-free survival (RFS), and different domains of QoL. Subgroup analysis was performed based on the provider-, type-, environment-, duration of intervention; cancer stage, and type. Pooled hazard ratios (HR) and standardized mean difference (SMD) with 95% confidence intervals (CI) were calculated using a random-effects model. The OS and RFS did not differ significantly between the two groups (OS:HR = 0.97; CI 0.87-1.08; RFS:HR = 0.99; CI 0.84-1.16). However, there was significant improvement in the intervention group in all the analyzed domains of QoL; in the global (SMD = 0.65; CI 0.35-0.94), emotional (SMD = 0.64; CI 0.33-0.95), social (SMD = 0.32; CI 0.13-0.51) and physical (SMD = 0.33; CI 0.05-0.60) domains. The effect of PI on QoL was generally positive immediately, 12 and 24 weeks after intervention, but the effect decreased over time and was no longer found significant at 48 weeks. The results were better in the breast cancer group and early stages of cancer. PIs do not prolong survival, but they significantly improve the QoL of cancer patients. PI should be added as standard of care 3-4 times a year, at least for patients with early-stage cancer.

Abstract
Background This study aims to (1) investigate the prevalence of anxiety, depression and severe fear of cancer recurrence or progression in gastrointestinal stromal tumor (GIST) patients treated in a curative or palliative setting, (2) compare their prevalence with a norm population, (3) identify factors associated with anxiety, depression and severe fear, and (4) study the impact of these psychological symptoms on health-related quality of life (HRQoL). Methods In a cross-sectional study, GIST patients completed the Hospital Anxiety and Depression Scale, Cancer Worry Scale, and EORTC QLQ-C30. Results Of the 328 patients, 15% reported anxiety, 13% depression, and 43% had severe fear. Anxiety and depression levels were comparable between the norm population and patients in the curative setting, but significantly higher for patients in the palliative setting. Having other psychological symptoms was associated with anxiety, while current TKI treatment and anxiety were associated with depression. Severe fear was associated with age, female sex, palliative treatment setting, anxiety, and GIST-related concerns. Conclusion GIST patients treated in a palliative setting are more prone to experience psychological symptoms, which can significantly impair their HRQoL. These symptoms deserve more attention in clinical practice, in which regular screening can be helpful, and appropriate interventions should be offered.

Abstract
The latest global cancer burden data released by the International Agency for Research on Cancer of the World Health Organization in 2020 shows that there were 19.29 million new cancer cases worldwide, with 4.57 million in China, ranking first. The number of cancer survivors is increasing, with a 5-year survival rate exceeding 85%, but there are emotional disorders. Cognitive behavioral therapy (CBT) can improve negative emotions and has significant effects on patients. However, there is a limited number of physicians and high costs, so internet interventions have become a solution. The feasibility of web-based interventions for breast cancer patients has been proven. Research on internet-delivered CBT is also increasing. The purpose of this study was to review the concept of web-based CBT and its application status in cancer survivors, in order to provide relevant intervention for scholars and provide reference and supplement for patients to provide psychological therapy.

Abstract
OBJECTIVE Cognitive behavioral stress management (CBSM) is a psychotherapy helping individuals develop adaptive behaviors, whose application in colorectal cancer (CRC) is rare. This randomized, controlled study intended to explore the effect of CBSM on anxiety, depression, and quality of life in CRC patients post tumor resection. METHODS One hundred and sixty CRC patients who received tumor resection were randomized (1:1) to receive weekly CBSM or usual care (UC) for 10 weeks after discharge (120 min for each session). Hospital Anxiety and Depression Scale (HADS) and Quality of Life Questionnaire-Core 30 (QLQ-C30) of each patient were assessed after randomization (M0), one month (M1), three months (M3), and six months (M6). RESULTS CBSM realized decreased HADS-anxiety scores at M1 (P = 0.044), M3 (P = 0.020), M6 (P = 0.003) compared to UC, so did anxiety rates at M3 (28.0% vs. 43.6%, P = 0.045), M6 (25.7% vs. 42.5%, P = 0.035), HADS-depression scores at M3 (P = 0.017), M6 (P = 0.005), and depression rates at M3 (25.3% vs. 41.0%, P = 0.040), M6 (22.9% vs. 41.1%, P = 0.020). Concerning the quality of life, CBSM achieved elevated QLQ-C30 global health status scores at M6 (P = 0.008), QLQ-C30 functions scores at M3 (P = 0.047), M6 (P = 0.031), and decreased QLQ-C30 symptoms scores at M3 (P = 0.048) and M6 (P = 0.039) compared with UC. By subgroup analyses, CBSM had a better utility on relieving anxiety, depression and improving quality of life in patients with higher education level and patients receiving adjuvant chemotherapy. CONCLUSION CBSM program alleviates anxiety, depression, and elevates quality of life in CRC patients post tumor resection.

Abstract
Aim: To provide the gastrointestinal stromal tumor patient's perspective on side effects of tyrosine kinase inhibitors and compare this with that of healthcare professionals. Materials & methods: Semi-structured interviews were conducted with 19 patients with an advanced or metastatic gastrointestinal stromal tumor, as well as six healthcare professionals, and five patients participated in a focus group. Thematic analysis was used to interpret the data. Results: Most participants (n = 29) reported gastrointestinal symptoms followed by tiredness (n = 25), edema (n = 22), muscle cramps (n = 21), skin problems (n = 21), eye problems (n = 11) and trouble sleeping (n = 10). Patients, but not healthcare professionals, reported cognitive problems or symptoms of depression. Conclusion: These results underline the importance of including the patient's perspective, as there is a gap in symptom reporting between patients and healthcare professionals.

Cancers (Basel) 2022; 14:cancers14071832.

Abstract
BACKGROUND The introduction of tyrosine kinase inhibitors (TKIs) has revolutionized the treatment of gastrointestinal stromal tumors (GISTs), resulting in a substantial gain in median overall survival. Subsequently, health-related quality of life (HRQoL) has become more relevant. Here, we systematically review the available literature on HRQoL issues and side effects of different TKIs registered for the treatment of GIST. METHODS A search through five databases was performed. Full reports in English describing HRQoL outcomes and/or side effects in GIST patients on TKI therapy were included. RESULTS A total of 104 papers were included; 13 studies addressed HRQoL, and 96 studies investigated adverse events. HRQoL in patients treated with imatinib, regorafenib, and ripretinib remained stable, whereas most sunitinib-treated patients reported a decrease in HRQoL. Severe fatigue and fear of recurrence or progression were specifically assessed as HRQoL issues and had a negative impact on overall HRQoL as well as psychological and physical well-being. The majority of studies focused on physician-reported side effects. Nearly all GIST patients treated with a TKI experienced at least one adverse event, mostly mild to moderate. CONCLUSIONS Despite the fact that almost all patients treated with a TKI experienced side effects, this did not seem to affect overall HRQoL during TKI therapy. In daily practice, it are the side effects that hamper a patient's HRQoL resulting in treatment adjustments, suggesting that the reported side effects were underestimated by physicians, or the measures used to assess HRQoL do not capture all relevant issues that determine a GIST patient's HRQoL.

Abstract
PURPOSE Treatment with the tyrosine kinase inhibitor (TKI) imatinib in patients with gastrointestinal stromal tumours (GIST) causes symptoms that could negatively impact health-related quality of life (HRQoL). Treatment-related symptoms are usually clinician-reported and little is known about patient reports. We used survey and online patient forum data to investigate (1) prevalence of patient-reported symptoms; (2) coverage of symptoms mentioned on the forum by existing HRQoL questionnaires; and (3) priorities of prevalent symptoms in HRQoL assessment. METHODS In the cross-sectional population-based survey study, Dutch GIST patients completed items from the EORTC QLQ-C30 and Symptom-Based Questionnaire (SBQ). In the forum study, machine learning algorithms were used to extract TKI side-effects from English messages on an international online forum for GIST patients. Prevalence of symptoms related to imatinib treatment in both sources was calculated and exploratively compared. RESULTS Fatigue and muscle pain or cramps were reported most frequently. Seven out of 10 most reported symptoms (i.e. fatigue, muscle pain or cramps, facial swelling, joint pain, skin problems, diarrhoea, and oedema) overlapped between the two sources. Alopecia was frequently mentioned on the forum, but not in the survey. Four out of 10 most reported symptoms on the online forum are covered by the EORTC QLQ-C30. The EORTC-SBQ and EORTC Item Library cover 9 and 10 symptoms, respectively. CONCLUSION This first overview of patient-reported imatinib-related symptoms from two data sources helps to determine coverage of items in existing questionnaires, and prioritize HRQoL issues. Combining cancer-generic instruments with treatment-specific item lists will improve future HRQoL assessment in care and research in GIST patients using TKI.
