Outcomes of Patients with Gastrointestinal Stromal Tumors in the Past Decade

Summary: | Background: Gastrointestinal stromal tumors (GISTs) are rare mesenchymal neoplasms of the gastrointestinal tract (GIT) that represent approximately 1 to 2 percent of primary gastrointestinal (GI) cancers. Owing to their rarity, very little is known about their overall epidemiology, and the prognostic factors of their pathology. The current study aimed to evaluate the independent determinants of mortality in patients diagnosed with GISTs over the past decade. Methods: Our study comprised 2374 patients diagnosed with GISTs from 2000 to 2017 from the Surveillance, Epidemiology, and End Results (SEER) database. We analyzed the baseline characteristics, and overall mortality (OM), as well as the cancer-specific mortality (CSM) of GISTs. Variables with a p value < 0.01 in the univariate Cox regression were incorporated into the multivariate Cox model, to determine the independent prognostic factors. Results: Multivariate Cox proportional hazard regression analyses of factors affecting the all-cause mortality and GIST-related mortality among US patients between 2010 and 2017 revealed a higher overall mortality in non-Hispanic Black patients (HR = 1.516, 95% CI 1.172–1.961, p = 0.002), patients aged 80+ (HR = 9.783, 95% CI 4.185–22.868, p = 0), followed by those aged 60–79 (HR = 3.408, 95% CI 1.488–7.807, p = 0.004); male patients (HR = 1.795, 95% CI 1.461–2.206, p < 0.001); patients with advanced disease with distant metastasis (HR = 3.865, 95% CI 2.977–5.019, p < 0.001), followed by cases with regional involvement via both direct extension and lymph node involvement (HR = 3.853, 95% CI 1.551–9.57, p = 0.004); and widowed patients (HR = 1.975, 95% CI 1.494–2.61, p < 0.001), followed by single patients (HR = 1.53, 95% CI 1.154–2.028, p = 0.003). The highest CSM was observed in the same groups, except widowed patients and patients aged 60–79. The highest CSM was also observed among patients that underwent chemotherapy (HR = 1.687, 95% CI 1.19–2.392, p = 0.003). Conclusion: In this updated study on the outcomes of patients with GISTs, we found that non-Hispanic Black patients, male patients, and patients older than 60 years have a higher mortality with GISTs. Furthermore, patients who have received chemotherapy have a higher GIST-specific mortality, and married patients have a lower mortality. However, we do not know to what extent these independent prognostic factors interact with each other to influence mortality. This study paves the way for future studies addres |
