List of all projects Quality assessment of multimodality treatment of patients with liver metastases of colorectal cancer in the Czech Comprehensive Cancer Centres

Coordinator Coordinator: Blaha Milan

Duration Duration: 2012–2015

Verifying the benefit of a multidisciplinary team-based approach in the comprehensive treatment of patients with liver metastases of colorectal cancer, evaluating the results in defined groups of patients according to selected parameters.

In the long term, the Czech Republic ranks among countries with the highest colorectal cancer incidence rates worldwide [1]. As much as 60% of CRC patients have liver metastases at the time of diagnosis or will develop them during treatment. Without treatment, patients survive less than one year on average. Patients treated chemotherapy or biochemotherapy – (B)CHMT – have been reported to survive for 12 to 24 months [2, 3]. Radical treatment (liver resection R0), which means a removal of liver tissue affected by the metastatic process, is considered an effective and potentially curative therapy. Radical treatment is essential for a subsequent administration of effective adjuvant (B)CHT, leading to 5-year survival in almost 60% of patients [4]. Studies focused on perioperative administration of CHMT have shown that survival increased by 10% in a three-year horizon [5]. At the time of project proposal (2011), only about 20% of patients were indicated for resection, mainly due to a technical unfeasibility, or the impossibility to maintain a sufficient volume of functional liver parenchyma [6]. Multimodal and personalised approach to each patient is an essential prerequisite for the successful treatment of CRC patients with liver metastases [7].

At the time of project proposal, adequate therapy was not provided to more than a half of CRC patients with liver metastases who were indicated for surgery in the Czech Republic [8]; moreover, there were no data to evaluate treatment effectiveness in this group of patients; many facilities did not apply decision mechanisms leading to the design of an optimal diagnostic and therapeutic process for a given patient; mechanisms for the evaluation of treatment outcomes and cost-effectiveness were not widely applied, and neither were methods for downstaging/downsizing [9].

It had been stated during a meeting at the Prague ONCO 2011 conference that CRC patients with synchronous or metachronous liver metastases have a chance of long-term survival only if the following requirements are met:

  1. care provided to these patients will be standardised and concentrated in specialised facilities (Comprehensive Cancer Centres - CCCs),
  2. a multidisciplinary team in the respective CCC will decide on the diagnostic and therapeutic process in a given patient,
  3. the above-mentioned combined procedures, including the perioperative administration of (B)CHMT will be monitored in terms of quality of care and treatment outcomes,
  4. data will be used from the Czech National Cancer Registry (CNCR) regarding the current and predicted incidence and prevalence rates of CRC patients, number of treated CRC patients with or without liver metastases in individual health care facilities in the Czech Republic, and possibly de-anonymised data from health care payers,
  5. clinical standard No. KKCCS0009 will be used for the diagnosis and treatment of patients with a secondary malignant tumour of liver, particularly in CRC (hereinafter referred to as “CS”) [10], which was developed by the Czech Surgical Society and other expert medical societies, in cooperation with the Czech National Reference Centre.

Project objectives:

  1. evaluating the effectiveness of multimodal therapy in CRC patients with liver metastases while monitoring quality indicators and treatment outcomes (proportion of resectability, safety of resection after a neoadjuvant (B)CHMT, early and late complications of resection, healing of the surgical wound, (B)CHMT hepatotoxicity, disease progression and other indicators), and comparing them with nationwide data acquired from the Czech National Cancer Registry,
  2. evaluating the benefit of neoadjuvant (B)CHMT in the groups of patients with primarily operable, primarily inoperable, and potentially resectable tumours, and comparing the percentage of resectability with published data,
  3. evaluating the use of CS in clinical practice,
  4. assessing the significance of measurement of selected molecular biomarkers including cell-free DNA (cfDNA) in samples of patients’ peripheral blood as a factor linked to treatment effectiveness [11]; serum biobanks in individual CCCs would be used for this purpose,
  5. monitoring the patients’ quality of life based on the Czech version of the EORTC QLQ - LMC21 questionnaire,
  6. assessing the treatment costs when CS is adhered to.
