RESUMO

Herein, we report a case of bullous dermatitis that occurred in a 61-year-old woman 5 days after beginning therapy with erlotinib for the treatment of stage IV pulmonary adenocarcinoma with metastases at the hypophyseal level. Skin reactions are the most common adverse drug reactions (ADRs) associated with epidermal growth factor receptor tyrosine kinase (EGFR-TK) inhibitors, and acneiform rash is the most frequently reported ADR in patients treated with erlotinib. To our knowledge, this is the first case of bullous dermatitis induced by erlotinib. This report highlights the need for additional research in the field of skin toxicity of EGFR-TK inhibitors.

RESUMO

BACKGROUND: Platinum-based doublets are the standard chemotherapy for lung cancer. The identification of markers associated with drug toxicity may improve the success of the treatment. Single nucleotide polymorphisms (SNPs) mapping into the genes involved in platinum transport or detoxification may explain the occurrence of toxicities. In this study, we evaluated the role of three SNPs in predicting the onset of adverse events for lung cancer patients receiving cisplatin or carboplatin in adjuvant, neo-adjuvant and metastatic settings. METHODS: Eighty-two patients affected by non-small-cell and small-cell lung cancer treated with cisplatin- or carboplatin-based chemotherapy (stage II-IV) were enrolled. Before genetic analysis, patients signed a written informed consent. DNA was extracted from peripheral blood samples and genotypes were determined by real-time PCR. We selected and analyzed three SNPs: ABCB1 c.3435C>T/rs1045642, ABCC2 -24C>T/rs717620 and GSTP1 c.313A>G/rs1695. Patient characteristics and genotypes were correlated with hematological, gastrointestinal and renal toxicity as recorded by Common Terminology Criteria for Adverse Event (CTCAE) v4.03. No neurological toxicity was observed in our patients. RESULTS: Variant alleles were present in 53% of patients for ABCB1 c.3435C >T, 18.3% for ABCC2 -24C> T, and 34.8% for GSTP1 c.313A>G. Heterozygous CT at ABCB1 c.3435 was associated to a lower risk of hematological toxicity compared to homozygous CC (OR = 0.20; 95% CI 0.05, 0.69; p = 0.01). Similar results were observed by genetic dominant model (CT + TT vs CC) and hematological toxicity (OR = 0.26; 95% CI 0.09, 0.79; p = 0.02). No other significant associations were found between toxicity and SNPs. Multivariate analysis confirmed an independent value for the ABCB1 c.3435 C >T polymorphism. CONCLUSIONS: The present study reveals that ABCB1 c.3435C>T polymorphism influences platinum toxicity. The T allele seems to exert a protective effect on the development of toxicities. Further studies, such as epigenetic regulation ones, are needed to validate and shed more light on this association.

RESUMO

AIM: Early palliative care (EPC) in oncology has shown sparse evidence of a positive impact on patient outcomes, quality of care outcomes and costs. PATIENTS AND METHODS: Data for this secondary analysis were taken from a trial of 207 outpatients with metastatic pancreatic cancer randomly assigned to receive standard cancer care plus on-demand EPC (standard arm) or standard cancer care plus systematic EPC (interventional arm). After 20 months' follow-up, 149 (80%) had died. Outcome measures were frequency, type and timing of chemotherapy administration, use of resources, place of death and overall survival. RESULTS: Some indices of end-of-life (EoL) aggressiveness had a favourable impact from systematic EPC. Interventional arm patients showed higher use of hospice services: a significantly longer median and mean period of hospice care (P = 0.025 for both indexes) and a significantly higher median and mean number of hospice admissions (both P < 0.010). In the experimental arm, chemotherapy was performed in the last 30 days of life in a significantly inferior rate with respect to control arm: 18.7% versus 27.8% (adjusted P = 0.036). Other non-significant differences were seen in favour of experimental arm. CONCLUSIONS: Systematic EPC showed a significant impact on some indicators of EoL treatment aggressiveness. These data, reinforced by multiple non-significant differences in most of the other items, suggest that quality of care is improved by this approach. This study is registered on ClinicalTrials.gov (NCT01996540).
