RESUMO
BACKGROUND: Depression is one of the major psychiatric morbidities in cancer patients. The purpose of our study was to evaluate the impact of depressive symptoms in the quality of life (QoL) of patients with breast cancer undergoing chemotherapy and monoclonal antibodies treatments. METHODS: Observational, cross-sectional study conducted between April and November 2016. To evaluate the QoL, the EORTC QLQ-C30 and QLQ-BR23 questionnaire were used. The patients were screened for depressive symptoms using the Hospital Anxiety and Depression Scale (HADS-D) and those with a positive HADS-D positive questionnaire were referenced to the Psychiatry and Mental Health Department for further assessment and follow-up. RESULTS: We included 45 female patients. Sixteen (35.6%) patients had a positive HADS-D questionnaire and depressive symptoms confirmed by a psychiatric physician. Of those patients, 7 (15.6%) had a major depressive episode confirmed by psychiatric interview. There was a significant association of depressive symptoms with the future perspectives scale (p = 0.022), breast symptoms scale (p = 0.011) and arm symptom scale (p = 0.005). Significant differences were found in the fatigue (p = 0.024), pain (p = 0.037) and dyspnea (p = 0.009) subscales being worse in patients with depressive symptoms. The association between having depressive symptoms or not was shown to be significant or marginally significant for the variables stage of the tumour (p = 0.057), presence of distant metastasis (p = 0.072) and previous diagnosis of depression (p = 0.011). The patients treated with regimens containing monoclonal antibodies presented better outcomes in various subscales of the EORTC QLQ-C30 and QLQ-B23 questionnaires than those patients treated with chemotherapy regimens without monoclonal antibodies. CONCLUSIONS: Despite the small sample of our study, this study provided evidence that depressive symptoms in patients with breast cancer undergoing chemotherapy and monoclonal antibodies treatments detrimentally reduced various aspects of QoL.
RESUMO
Lung cancer is one of the most commonly diagnosed malignancies and it causes more than 1 million deaths each year worldwide. Small-cell lung cancer (SCLC) accounts for about 15 to 20% of all lung cancers and it is an extremely aggressive cancer, having a response rate of 60-80% with the standard first-line chemotherapy (CT). Topotecan is a topoisomerase I inhibitor currently approved for relapsed SCLC. The authors reviewed the clinical files of SCLC's patients (pts) of a single institution, the Portuguese Institute of Oncology-Porto Centre, in a five year period. The end-points were to evaluate response rates (RR), time to progression (TTP), overall survival (OS) and toxicity profile of topotecan as a second-line treatment of SCLC. From January of 2002 to December of 2006, it was diagnosed 146 pts with SCLC, 32 were submitted to second-line treatment and 23 with topotecan. The RR was 17.4%, median TTP and median survival after topotecan were 2.8 months and 6.3 months, respectively, and median OS was 17.5 months. The incidence of grade 3 and 4 adverse events was 16.6 and 2.6%, respectively. Topotecan showed clinical activity in our unselected daily patients with relapsed SCLC, with acceptable toxicity, in accordance with the published literature.
