Emotional distress in cancer survivors from various ethnic backgrounds: Analysis of the multi-ethnic HELIUS study.

PURPOSE: Insight into emotional distress of cancer survivors from ethnic minority groups in Europe is scarce. We aimed to compare distress levels of survivors from ethnic minorities to that of the majority population, determine whether the association between having cancer (yes vs. no) and distress differs among ethnic groups and investigate sociocultural correlates of distress. METHODS: Cross-sectional data were derived from HELIUS, a multi-ethnic cohort study conducted in the Netherlands. Of 19,147 participants, 351 were diagnosed with cancer (n = 130 Dutch, n = 75 African Surinamese, n = 53 South-Asian Surinamese, n = 43 Moroccan, n = 28 Turkish, n = 22 Ghanaian). Distress (PHQ-9, MCS-12) and correlates were assessed by self-report. Cancer-related variables were derived from the Netherlands Cancer Registry. RESULTS: Survivors were on average 7 years post-diagnosis. Survivors from South-Asian Surinamese, Moroccan, Turkish and Ghanaian origin reported more distress than survivors from Dutch origin (effect sizerange : 0.44-1.17; adjusted models). The association between having cancer or not with distress differed in direction between Dutch and the non-Dutch ethnic groups: Non-Dutch cancer patients tended to have more distress than their cancer-free peers, whereas Dutch cancer patients tended to have less distress than their cancer-free peers. For Moroccan and Turkish patients, the acculturation style of separation/marginalization, compared to integration/assimilation, was associated with higher depressive symptoms. In analyses pooling data from all ethnic minorities, lower health literacy, lower emotional support satisfaction and younger age at the time of migration were associated with higher depressive symptoms. Lower health literacy, fewer emotional support transactions, and more frequent attendance at religious services were associated with worse mental health. CONCLUSION: Cancer survivors from ethnic minorities experience more distress than those from the majority population. Culturally sensitive supportive care should be considered.

Late Toxicity and Health-Related Quality of Life Following Definitive Chemoradiotherapy for Esophageal Cancer: A Systematic Review and Meta-analysis.

PURPOSE: Definitive chemoradiotherapy (dCRT) is a treatment option with curative intent for patients with esophageal cancer that could result in late toxicities and affect health-related quality of life (HRQoL). This study aimed to review the literature and perform a meta-analysis to investigate the effect of dCRT on late toxicities and HRQoL in esophageal cancer. METHODS AND MATERIALS: A systematic search was performed in MEDLINE, EMBASE, and PsychINFO. Prospective phase II and III clinical trials, population-based studies, and retrospective chart reviews investigating late toxicity or HRQoL after dCRT (≥50 Gy) were included. The HRQoL outcomes were analyzed using linear mixed-effect models with restricted cubic spline transformation. Any HRQoL changes of ≥10 points were considered clinically relevant. The risk of toxicities was calculated using the number of events and the total study population. RESULTS: Among 41 included studies, 10 assessed HRQoL and 31 late toxicity. Global health status remained stable over time and improved after 36 months compared with baseline (mean change, +11). Several tumor-specific symptoms, including dysphagia, eating restrictions, and pain, improved after 6 months compared with baseline. Compared with baseline, dyspnea worsened after 6 months (mean change, +16 points). The risk of any late toxicity was 48% (95% CI, 33%-64%). Late toxicity risk of any grade for the esophagus was 17% (95% CI, 12%-21%), pulmonary 21% (95% CI, 11%-31%), cardiac 12% (95% CI, 6%-17%), and any other organ 24% (95% CI, 2%-45%). CONCLUSIONS: Global health status remained stable over time, and tumor-specific symptoms improved within 6 months after dCRT compared with baseline, with the exception of dyspnea. In addition, substantial risks of late toxicity were observed.

The role of transforming growth factor ß in upper gastrointestinal cancers: A systematic review.

Esophageal and gastric malignancies are associated with poor prognosis, in part due to development of recurrences or metastases after curative treatment. The transforming growth factor ß (TGF-ß) pathway might play a role in the development of treatment resistance. In this systematic review, we provide an overview of preclinical studies investigating the role of TGF-ß in esophageal and gastric malignancies. We systematically searched MEDLINE/PubMed and EMBASE for eligible preclinical studies describing the effect of TGF-ß or TGF-ß inhibition on hallmarks of cancer, such as proliferation, migration, invasion, angiogenesis and immune evasion. In total, 2107 records were screened and 45 articles were included, using mouse models and 45 different cell lines. TGF-ß failed to induce apoptosis in twelve of sixteen tested cell lines. TGF-ß could either decrease (five cell lines) or increase proliferation (seven cell lines) in gastric cancer cells, but had no effect in esophageal cancer cells. In all esophageal and all but two gastric cancer cell lines, TGF-ß increased migratory, adhesive and invasive capacities. In vivo studies showed increased metastasis in response to TGF-ß treatment. Additionally, TGF-ß was shown to induce vascular endothelial growth factor production and differentiation of cancer-associated fibroblasts and regulatory T-cells. In conclusion, we found that TGF-ß enhances hallmarks of cancer in most gastric and esophageal cancer cell lines, but not in all. Therefore, targeting the TGF-ß pathway could be an attractive strategy in patients with gastric or esophageal cancer, but additional clinical trials are needed to define patient groups who would benefit most.
