Aggressiveness in systemic anticancer therapy at the end of life in an oncology center.

Introduction: An increasing aggressiveness in cancer treatment at the end of life (EoL) has been reported in several, but not all, countries. 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. Taking into consideration previously published data, it can be tentatively concluded that the use of SACT increased in the last month and the last week of life.

Factors Associated With Long Survival in Patients With Cancer Admitted to Palliative Care: An Exploratory Study.

Objective: Some patients with cancer admitted to palliative care have relatively long survivals of 1 year or more. The objective of this study was to find out factors associated with prolonged survival. Methods: Retrospective case-control study comparing the available data of patients with cancer who survived more than 1 year after admission in a palliative care service with patients with cancer who survived 6 months or less. The intended proportion was 4 controls for each case. Patients were identified through electronic records from 2012 until 2018. Results: And 1721 patients were identified. Of those patients, 111 (6.4%) survived for at least 1 year, and 363 (21.1%) were included as controls according to the established criteria. The intended proportion could not be reached; the proportion was only 3.3:1. The median survival of cases was 581 days (range: 371-2763), and the median survival of controls was 57 days (range: 1-182). In the multivariable analysis, patients with a hemoglobin ≥ 10.6 g/dL and a creatinine level >95 µmol/L had a higher probability of living more than 1 year. In contrast, patients with abnormal cognition, pain, anorexia, liver metastases, an Eastern Cooperative Oncology Group performance status >1, and a neutrophil/lymphocyte ratio ≥ 3.43 had a low probability of living more than 1 year. Conclusion: Several factors were statistically associated positively or negatively with prolonged survival. However, the data of this study should be confirmed in other studies.

Role of intravenous iron in the treatment of anemia in patients with gastrointestinal tract tumors undergoing chemotherapy: a single-center, observational study.

PURPOSE: The prevalence of anemia ranges between 30% and 90% in cancer patients, affecting the health status, quality of life, and treatment outcome. Therefore, a proper diagnosis and management of anemia is crucial in these patients. Iron deficiency is diagnosed in~32%-60% of the cases. In this observational study, we evaluated the efficacy and safety of intravenous iron (ferric carboxymaltose [FCM], Ferinject®) in the treatment of iron-deficiency anemia in patients with gastrointestinal tumors undergoing palliative or adjuvant chemotherapy. PATIENTS AND METHODS: Thirty patients with gastrointestinal tumors undergoing chemotherapy diagnosed with iron-deficiency anemia were included in the study and received at least one FCM administration. The need for iron replacement therapy was evaluated by the assessment of hemoglobin and iron status parameters, and patients could be treated with FCM during 12-14 weeks. Paired t-test approach was used to evaluate the mean differences between the baseline and the end of the study. A p-value of <0.05 was considered statistically significant. RESULTS: Data showed that there was a statistically significant increase in the mean of hemoglobin (10.3 vs 11.2 g/dL), ferritin (230.3 vs 877.0 ng/mL), transferrin saturation (13.0% vs 19.7%), and serum iron (42.3 vs 59.6 mg/mL) from the baseline to the end of the study in cancer patients. Most of the patients (n=25) were only administered one dose of FCM. There was one FCM-related adverse event during the study. CONCLUSION: FCM was well tolerated and had a positive impact in the treatment of iron-deficiency anemia in patients with gastrointestinal tract tumors undergoing chemotherapy.

Personalizing therapies for gastric cancer: molecular mechanisms and novel targeted therapies.

Globally, gastric cancer is the 4(th) most frequently diagnosed cancer and the 2(nd) leading cause of death from cancer, with an estimated 990000 new cases and 738000 deaths registered in 2008. In the advanced setting, standard chemotherapies protocols acquired an important role since last decades in prolong survival. Moreover, recent advances in molecular therapies provided a new interesting weapon to treat advanced gastric cancer through anti-human epidermal growth factor receptor 2 (HER2) therapies. Trastuzumab, an anti-HER2 monoclonal antibody, was the first target drug in the metastatic setting that showed benefit in overall survival when in association with platinum-5-fluorouracil based chemotherapy. Further, HER2 overexpression analysis acquired a main role in predict response for trastuzumab in this field. Thus, we conducted a review that will discuss the main points concerning trastuzumab and HER2 in gastric cancer, providing a comprehensive overview of molecular mechanisms and novel trials involved.
