Purpose: The aim of this phase III trial was to compare the efficacy and safety of bevacizumab alone with those of bevacizumab and capecitabine plus oxaliplatin (XELOX) as maintenance treatment following induction chemotherapy with XELOX plus bevacizumab in the first-line treatment of patients with metastatic colorectal cancer (mCRC). Patients and Methods: Patients were randomly assigned to receive six cycles of bevacizumab, capecitabine, and oxaliplatin every 3 weeks followed by XELOX plus bevacizumab or bevacizumab alone until progression. The primary endpoint was the progression-free survival (PFS) interval; secondary endpoints were the overall survival (OS) time, objective response rate (RR), time to response, duration of response, and safety. Results: The intent-to-treat population comprised 480 patients (XELOX plus bevacizumab, n = 239; bevacizumab, n = 241); there were no significant differences in baseline characteristics. The median follow-up was 29.0 months (range, 0–53.2 months). There were no statistically significant differences in the median PFS or OS times or in the RR between the two arms. The most common grade 3 or 4 toxicities in the XELOX plus bevacizumab versus bevacizumab arms were diarrhea, hand–foot syndrome, and neuropathy. Conclusion: Although the noninferiority of bevacizumab versus XELOX plus bevacizumab cannot be confirmed, we can reliably exclude a median PFS detriment >3 weeks. This study suggests that maintenance therapy with singleagent bevacizumab may be an appropriate option following induction XELOX plus bevacizumab in mCRC patients., Eduardo Díaz-Rubio, Auxiliadora Gómez-España, Bartomeu Massutí, Javier Sastre, Albert Abad, Manuel Valladares, Fernando Rivera, Maria J.Safont, Purificación Martínez De Prado, Manuel Gallén, Encarnación González, Eugenio Marcuello, Manuel Benavides, Carlos Fernández-Martos, Ferrán Losa, Pilar Escudero, Antonio Arrivi, Andrés Cervantes, Rosario Dueñas, Amelia López-Ladrón, Adelaida Lacasta, Marta Llanos, Jose M.

V posledních letech došlo ke změnám přístupu v léčbě karcinomu rekta. Léčba karcinomu rekta je příkladem komplexní multimodální léčby, zahrnující chirurgickou operaci, radioterapii, chemoterapii či konkomitantní chemoradioterapii. Autoři v následujícím textu shrnují dosavadní poznatky a doporučení konkomitantní chemoradioterapie rekta., In recent years, there have been changes in approaching the treatment for rectal carcinoma. The treatment for rectal carcinoma is an example of a comprehensive multimodal therapy which includes surgery, radiotherapy, chemotherapy or concomitant chemoradiotherapy. The authors summarize the existing knowledge and recommendations for concomitant chemoradiotherapy of the rectum., Luboš Holubec, Tomáš Svoboda, Jindřich Fínek, and Lit.: 32
