However, the impact of thrombocytosis on the prognosis of gastric cancer is not yet well defined. The aim of this study was to assess the prevalence and prognostic value of thrombocytosis in patients with gastric cancer. METHODS: This was a retrospective study of patients with gastric carcinoma treated surgically, with curative intent, in our hospital, Centro Hospitalar Vila Nova de Gaia/Espinho, between January 2009 and December 2019. Clinical files were consulted and clinicopathological characteristics were analyzed. RESULTS: In the present sample (n = 352), the prevalence of pretreatment thrombocytosis was 16.5%. Thrombocytosis was associated with more advanced T stage, greater number of metastatic nodes, and more frequent lymphatic and venous permeation. The presence of thrombocytosis had a negative impact on disease-free survival (hazard ratio [HR] 3.54, 95% confidence interval [CI] 2.35–5.33, P < .001) and overall survival (HR 4.45, 95% CI 2.95–6.71, P < .001). CONCLUSIONS: The presence of pretreatment thrombocytosis had a negative impact on overall survival and disease-free survival and thus could be used as an independent prognostic factor.","PeriodicalId":74479,"journal":{"name":"Porto biomedical journal","volume":"45 16","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140076801","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to see how aggressive cancer treatment is at the EoL in an oncology center. Methods: Retrospective study of patients 18 years or older with a solid cancer diagnosis who died in 2017. The focus was systemic anticancer therapy (SACT), excluding hormonotherapy. Results: In 2017, 2024 patients with solid tumors died. Of those patients, 1262 (62%) were male, and the median age was 69 (range 19–97) years. The most frequent primary cancer was lung cancer, followed by colorectal and stomach cancers, and 740 (37%) patients had metastatic disease. The median interval between SACT and death was 61 days. Of the patients undergoing SACT, 216 (27%) did it in the last month of life, 174 (22%) between 8 and 30 days from death, and 42 (5%) in the last week. On multivariable analysis, head and neck, colorectal, breast, and melanoma primaries; age group (older than 65 years); and metastatic disease had statistical significance associated with SACT. Of these variables, only metastatic disease is more likely to undergo SACT. Conclusion: This study confirms the relatively frequent aggressiveness in cancer treatment at the EoL.
