RESUMO

Colorectal cancer is a disease of older patients, but few guidelines directly address age in their recommendations. Older patients may present comorbidities that affect the choice of chemotherapy, and care must be taken when choosing the best approach. This narrative review aimed to describe the literature regarding approved oral agents for third-line treatment in older patients with refractory metastatic colorectal cancer, regorafenib, and trifluridine/tipiracil (FTD/TPI).

RESUMO

BACKGROUND: Neoadjuvant chemoradiotherapy (neoCRT) followed by surgery is the standard of care for locally advanced rectal cancer (LARC), but the emergence of different drug regimens may result in different response rates. Good clinical response translates into greater sphincter preservation, but quality of life (QOL) may be impaired after treatment due to chemoradiotherapy and surgical side effects. OBJECTIVE: To prospectively evaluate the impact of clinical response and surgical resection on QOL in a randomized trial comparing two different neoCRT regimens. METHODS: Stage II and III rectal cancer patients were randomized to receive neoCRT with either capecitabine (group 1) or 5-Fu and leucovorin (group 2) concomitant to long-course radiotherapy. Clinical downstaging was accessed using MRI 6-8 weeks after treatment. EORTCs QLQ-C30 and CR38 were applied before treatment (T0), after neoCRT (T1), after rectal resection (T2), early after adjuvant chemotherapy (T3), and 1 year after the end of treatment or stoma closure (T4). The Wexner scale was used for fecal incontinence evaluation at T4. A C30SummaryScore (Geisinger and cols.) was calculated to compare QOL results. RESULTS: Thirty-two patients were assigned to group 1 and 31 to group 2. Clinical downstaging occurred in 70.0% of group 1 and 53.3% of group 2 (p = 0.288), and sphincter preservation was 83.3% in group 1 and 80.0% in group 2 (p = 0.111). No significant difference in QOL was detected when comparing the two treatment groups after neoCRT using QLQ-C30. However, the CR38 module detected differences in micturition problems (15.3 points), gastrointestinal problems (15.3 points), defecation problems (11.8 points), and sexual satisfaction (13.3 points) favoring the capecitabine group. C30SummaryScore detected significant improvement comparing T0 to T1 and deterioration comparing T1 to T2 (p = 0.025). The mean Wexner scale score was 9.2, and a high score correlated with symptoms of diarrhea and defecation problems at T4. CONCLUSIONS: QOL was equivalent between groups after neoCRT except for micturition problems, gastrointestinal problems, defecation problems, and sexual satisfaction favoring the capecitabine arm after. The overall QOL using the C30SummaryScore was improved after neoCRT, but decreased following rectal resection, returning to basal levels at late evaluation. Fecal incontinence was high after sphincter preservation. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT03428529.

RESUMO

Objetivo: Avaliar a custo-efetividade da trifluridina/cloridrato de tipiracila (FTD/TPI) em comparação ao melhor cuidado de suporte (sigla em inglês BSC, best supportive care) e ao regorafenibe para o tratamento em pacientes com câncer colorretal metastático (CCRm) politratados (terceira linha ou linhas posteriores) sob a perspectiva de pagadores privados no Brasil. Métodos: Foi construído um modelo de sobrevida particionado considerando três estados de saúde. A efetividade foi medida em anos-vida ganhos e Quality-Adjusted Life Years (QALY). Os custos foram obtidos a partir da perspectiva do sistema de saúde privado brasileiro considerando um horizonte temporal de cinco anos. Também foram realizadas análises de sensibilidade univariada e probabilística para avaliar a robustez do modelo. Resultados: A utilização de FTD/TPI pode gerar melhores desfechos clínicos versus BSC e economia de recursos versus regorafenibe. FTD/TPI proporcionou mais 0,098 anos de vida por paciente e uma qualidade de vida incremental de 0,072, comparada ao BSC. Já em relação ao regorafenibe, a FTD/TPI apresentou redução de R$ 2.088,49 nos custos por paciente e benefícios clínicos com incremento marginal. Conclusão: FTD/TPI representa uma opção de tratamento de CCRm custo-efetiva, comparada ao regorafenibe, na perspectiva de pagadores privados no Brasil

Objective: To determine the cost-effectiveness analysis of trifluridine/tipiracil chloridrate (FTD/TPI) compared to best supportative care (BSC) and regorafenib for the treatment of polytreated metastatic colorectal carcinoma (mCRC) (3rd line or later lines) in the private payer perspective in Brazil. Methods: A partitioned survival model was developed based on three health states. Effectiveness was measured in life-years gained and Quality-Adjusted Life Years (QALYs). Costs were obtained from the perspective of the supplementary healthcare system in Brazil considering a time horizon of five years. Univariate and probabilistic sensitivity analyses were performed to evaluate the robustness of the model. Results: The use of FTD/TPI may generate better clinical outcomes versus BSC and resource savings versus regorafenib. FTD/TPI provided more 0,098 years of life per patient and an incremental quality of life of 0,072 compared to BSC. Regarding regorafenib, FTD/TPI provided a cost reduction of R$ 2.088,49 per patient and similar clinical benefits. Conclusion: FTD/TPI represents a cost-effective treatment option for mCRC compared to regorafenib from the perspective of the supplementary healthcare system in Brazil

RESUMO

PURPOSE: In Brazil, patients with gastric cancer have not been systematically followed-up and evaluated, thus data regarding patterns of care and outcomes are scarce or missing. The objective of this study was to evaluate patterns of care of advanced gastric cancer in standard practice in Brazil. METHODS: This was an observational, multicenter, retrospective study, which included patients with metastatic and/or unresectable gastric cancer (MGC) who underwent at least one line of treatment. RESULTS: We analyzed data on 155 patients diagnosed with MGC, most are men (57.4%), with mean age of 61.9 years at diagnosis, with 99 (63.9%) from the public healthcare system and 56 (36.1%) from the private setting. Platinum- and/or fluoropyrimidine-containing regimens prevailed as first-line therapy, while irinotecan was the most used regimen in the second and in the third lines. More than 40% of patients underwent only one line of systemic therapy, of which around 40% either died during the treatment or went on to best supportive care (BSC) only. The remaining patients received further treatment lines. A fifth of the patients in the study died within two months after discontinuation of the first-line treatment. Adverse events, use of concomitant medications, support procedures, outpatient visits, and hospitalizations were reported for most patients, especially in the first and second lines of treatment and during exclusive BSC. CONCLUSIONS: Survival during or after the first-line chemotherapy remains poor among patients with MGC. Adverse events and health resource use were common in the first and second lines of treatment and in exclusive BSC. These results suggest that there is space for improvement in the treatment of MGC in Brazil.

RESUMO

INTRODUCTION: Outcomes data on Non-Small Cell Lung Cancer (NSCLC) are scarce with regard to the private health care in Brazil. The aim of this study was to describe the characteristics, treatments performed, and the survival of patients with NSCLC in a Brazilian private oncologic institution. METHODS: Medical charts from patients treated between 1998 and 2010 were reviewed, and data were transferred to a clinical research form. Long-term follow-up and survival estimates were enabled through active surveillance. RESULTS: Five hundred sixty-six patients were included, and median age was 65 years. Most patients were diagnosed in advanced stages (79.6% III/IV). The overall survival was 19.0 months (95%CI 16.2 - 21.8). The median survival was 99.7, 32.5, 20.2, and 13.3 months for stages I, II, III, and IV, respectively (p < 0.0001). Among patients receiving palliative chemotherapy, the median survival was 12.2 months (95%CI 10.0 - 14.4). CONCLUSIONS: The outcomes described are favorably similar to the current literature from developed countries. Besides the better access to health care in the private insurance scenario, most patients are still diagnosed in late stages. .

INTRODUÇÃO: Dados de desfechos em câncer de pulmão de células não pequenas (CPCNP) são escassos no contexto da saúde suplementar no Brasil. O objetivo deste estudo foi descrever as características, tratamentos realizados e a sobrevida desses pacientes em uma instituição oncológica privada brasileira. MÉTODOS: Foram revisados os prontuários de pacientes atendidos entre 1998 e 2010 com diagnóstico de CPCNP. Os dados foram transferidos para uma ficha clínica individual e posteriormente analisados. Pacientes ou familiares foram contatados a fim de otimizar o seguimento e a estimativa da sobrevida. RESULTADOS: Foram incluídos 566 pacientes, com idade mediana de 65 anos. Predominaram os diagnósticos em estádios avançados (79,6% III/IV). A sobrevida mediana foi de 19,0 meses (IC95% 16,2 - 21,8), sendo de 99,7, 32,5, 20,2 e de 13,3 meses nos estádios I, II, III e IV, respectivamente (p < 0,0001). Entre os pacientes que receberam quimioterapia paliativa, a sobrevida mediana foi de 12,2 meses (IC95% 10,0 - 14.4). CONCLUSÕES: Os desfechos encontrados se assemelham aos de países desenvolvidos. Apesar do maior acesso médico em pacientes com cobertura de planos de saúde, a maioria dos diagnósticos ocorre tardiamente. .

RESUMO

BACKGROUND: KRAS mutations are frequently found in colorectal cancer (CRC) indicating the importance of its genotyping in the study of the molecular mechanisms behind this disease. Although major advances have occurred over the past decade, there are still important gaps in our understanding of CRC carcinogenesis, particularly whether sex-linked factors play any role. METHODS: The profile of KRAS mutations in the Brazilian population was analyzed by conducting direct sequencing of KRAS codons 12 and 13 belonging to 8,234 metastatic CRC patient samples. DNA was extracted from paraffin-embedded tissue, exon 1 was amplified by PCR and submitted to direct sequencing. The data obtained was analysed comparing different geographical regions, gender and age. RESULTS: The median age was 59 years and the overall percentage of wild-type and mutated KRAS was 62.8% and 31.9%, respectively. Interestingly, different percentages of mutated KRAS patients were observed between male and female patients (32.5% versus 34.8%, respectively; p = 0.03). KRAS Gly12Asp mutation was the most prevalent for both genders and for most regions, with the exception of the North where Gly12Val was the most frequent mutation found. CONCLUSIONS: To the best of our knowledge this is one of the largest cohorts of KRAS genotyping in CRC patients and the largest to indicate a higher incidence of KRAS mutation in females compared to males in Brazil. Nevertheless, further research is required to better address the impact of gender differences in colorectal cancer.
