Criteria and indicators to evaluate quality of care in genitourinary tumour boards.

PURPOSE: Genitourinary (GU) multidisciplinary tumour boards (GUMTBs) are key components of patient care, as they might lead to changes in treatment plan, improved survival, and increased adherence to guidelines. However, there are no guidelines on how GUMTBs should operate or how to assess their quality of performance. METHODS: A systematic literature review was conducted to identify criteria and indicators to evaluate quality in GUMTBs. A scientific committee-comprising 12 GU cancer specialists from seven disciplines-proposed a list of criteria and developed indicators, evaluated in two rounds of Delphi method. Appropriateness and utility of indicators were scored using a 9-point Likert scale. Consensus was defined as at least two-thirds of Delphi respondents selecting a score sub-category that encompassed the median score of the group. RESULTS: Forty-five criteria were selected to evaluate the quality of GUMTBs covering five dimensions: organisation, personnel, protocol and documentation, resources, and interaction with patients. Then, 33 indicators were developed and evaluated in the first round of Delphi, leading to a selection of 26 indicators in two dimensions: function, governance and resources, and GUMTB sessions. In the second round, consensus was reached on the appropriateness of all 26 indicators and on the utility of 24 of them. Index cards for criteria and indicators were developed to be used in clinical practice. CONCLUSIONS: Criteria and indicators were developed to evaluate the quality of GUMTBs, aiming to serve as a guide to improve quality of care and health outcomes in patients with GU cancer.

The Economic Burden of Localized Prostate Cancer and Insights Derived from Cost-Effectiveness Studies of the Different Treatments.

Prostate cancer has huge health and societal impacts, and there is no clear consensus on the most effective and efficient treatment strategy for this disease, particularly for localized prostate cancer. We have reviewed the scientific literature describing the economic burden and cost-effectiveness of different treatment strategies for localized prostate cancer in OECD countries. We initially identified 315 articles, studying 13 of them in depth (those that met the inclusion criteria), comparing the social perspectives of cost, time period, geographical area, and severity. The economic burden arising from prostate cancer due to losses in productivity and increased caregiver load is noticeable, but clinical decision-making is carried out with more subjective variability than would be advisable. The direct cost of the intervention was the main driver for the treatment of less severe cases of prostate cancer, whereas for more severe cases, the most important determinant was the loss in productivity. Newer, more affordable radiotherapy strategies may play a crucial role in the future treatment of early prostate cancer. The interpretation of our results depends on conducting thorough sensitivity analyses. This approach may help better understand parameter uncertainty and the methodological choices discussed in health economics studies. Future results of ongoing clinical trials that are considering genetic characteristics in assessing treatment response of patients with localized prostate cancer may shed new light on important clinical and pharmacoeconomic decisions.

Measures to evaluate quality of care in renal cancer: results of a Delphi study in Spain.

PURPOSE: To review current measures for renal cancer care and develop a comprehensive and updated list of measures for their practical use in Spain. METHODS: The study was developed by Fundación ECO, a Spanish foundation aiming to improve oncology quality of care. A systematic literature review was carried out to identify measures and knowledge gaps. A scientific committee composed of nine experts reviewed the literature findings and added measures. A preliminary list of 42 measures was evaluated with the Delphi method to gather feedback from 47 medical oncology experts in Spain. Experts scored the appropriateness of the measures and ranked their priority in two consecutive online surveys. The scientific committee reviewed the Delphi results and developed the measures. A technical group from Universidad Francisco de Vitoria conducted and oversaw the Delphi method. RESULTS: The Delphi method led to consensus on all 42 measures. The scientific committee used a prioritisation matrix to select 25 of these measures for evaluating quality of care in renal cancer. These measures regarded structure, process, and outcome and covered general management, diagnosis, treatment, follow-up, and evaluation of health outcomes. Easy-to-use index cards were developed for all 25 measures, including their definition, formula, acceptable level of attainment, and rationale. CONCLUSIONS: This manuscript aims to provide healthcare professionals with expert- and evidence-based measures that are useful for evaluating quality of care in renal cancer in Spain and cover all aspects and stages.

Predictive and prognostic impact of tumour-infiltrating lymphocytes in triple-negative breast cancer treated with neoadjuvant chemotherapy.

INTRODUCTION: In locally and locally advanced triple-negative breast cancer (TNBC), neoadjuvant chemotherapy (NAC) only induces a pCR in 30-35% of patients. Clinical and pathological factors are not enough to distinguish the patients who have no chance of a pCR or not. The tumour microenvironment is critical for cancer and tumour-infiltrating lymphocytes (TIL). Moreover, the NAC scenario is the perfect setting to study possible changes in TIL levels. MATERIAL AND METHODS: Using our prospective maintained breast cancer (BC) database, we identified 164 TNBC patients treated with NAC between 1998 and 2015 with enough samples of diagnostic biopsy and after surgery. Evaluation of TILs before and after NAC followed a standardised methodology for visual assessment on haematoxylin-eosin sections and the amounts of TILs were quantitated in deciles. We categorised lymphocyte-predominant breast cancer cutoff according to a receiver operating characteristic (ROC) analysis. We categorised LPBC as involving > 40% lymphocytic infiltration tumour stroma. The primary end point was predictive value of TILs to NAC, and the secondary end point was disease-free survival (DFS). DFS was analysed using the Kaplan-Meier method and the groups were compared with a long-rank test. Univariate and multivariate Cox models were used to generate hazard ratios for determining associations between variables such as TIL after NAC and DFS. RESULTS: A total of 164 TNBC patients were treated with NAC and surgery. The main patients' characteristics are listed in Table 1. We identify different pathological complete response to anthracycline and taxane-based NAC; LPBC subgroup 51 from 58 patients (88%) pCR versus non- lymphocyte-predominant breast cancer (LPBC) subgroup 10 from 106 (9%) pCR, p = 0.001. At a median follow-up of 78 months, LPBC was associated with better DFS; the three-year Kaplan-Meier estimates for DFS were 2% and 30 % for patients with LPBC and non-LPBC, respectively, p = 0.01. Univariate and multivariate analysis confirmed TIL to be an independent prognostic marker of DFS. CONCLUSIONS: Tumour-infiltrating lymphocytes could be routinely used in locally advanced TNBC treated with anthracycline and taxane, such as biomarker, to be enabled the identification of different two subgroups: LPBC patients have a very high response to NAC pCR 88%, meanwhile non-LPBC patients only achieve 9%. Moreover, non-LPBC patients have a worse prognosis than LPBC patients. This data verified the predictive and prognostic value of TIL.

Phase II trial with letrozole to maximum response as primary systemic therapy in postmenopausal patients with ER/PgR[+] operable breast cancer.

PURPOSE: Letrozole is superior to tamoxifen in terms of response and breast preservation rates as primary systemic therapy (PST) in postmenopausal women with ER-positive early breast cancer. However, the optimum duration of endocrine PST remains uncertain. METHODS: A phase 2 multicentre, open-label trial was conducted to evaluate the efficacy of letrozole over a preoperative period of 4 months to 1 year. Seventy postmenopausal patients (over 65 years) were recruited in four centers. The primary endpoint was to establish the optimal duration of treatment defined as the time required to attain the maximum response by clinical palpation. RESULTS: The median age of the group was 79 years (66-91) and the median tumour size 35 mm (range 25-100 mm). No severe adverse events were reported. Fifty-six patients were evaluable for the primary objective. A total of 43 patients (76.8%) achieved an objective response; 29 (51.8%) being partial and 14 (25.0%) complete. The median time to objective response was 3.9 months (95% CI, 3.3-4.5) and the median time to maximum response was 4.2 months (95% CI, 4.0-4.5), although 20 (37.1%) patients achieved the maximal response within 6-12 months. CONCLUSIONS: Letrozole shows a high activity and excellent tolerability as neoadjuvant therapy in elderly patients with endocrine-dependent breast cancer. Four to six months of letrozole as PST is an optimum duration with modest benefits thereafter.

Feasibility and tolerability of sequential doxorubicin/paclitaxel followed by cyclophosphamide, methotrexate, and fluorouracil and its effects on tumor response as preoperative therapy.

PURPOSE: The European Cooperative Trial in Operable breast cancer (ECTO) randomly tested whether efficacy of adjuvant doxorubicin followed by i.v. cyclophosphamide, methotrexate, and fluorouracil (CMF; doxorubicin-->CMF, arm A) could be improved by adding paclitaxel (doxorubicin/paclitaxel-->CMF) as adjuvant (arm B) or primary systemic therapy (PST, arm C). We report here feasibility, tolerability, locoregional antitumor activity, and breast conservation rate. METHODS: A total of 1,355 women entered the study. Feasibility and safety were compared in arm A versus arms B plus C. Surgical findings were compared in arms A plus B versus arm C. RESULTS: Grade 3 or 4 National Cancer Institute toxicities were low (<5%) in all arms. Neuropathy was more frequent in the paclitaxel-containing arms (grade 2, 20.5% versus 5.0%; grade 3, 1.3% versus 0.2%). At 31 months of follow-up, asymptomatic drop of left ventricular ejection fraction was similar in all arms, whereas symptomatic cardiotoxicity was recorded in three patients (0.5%) in A and in three patients (0.3%) in B plus C. PST induced clinical complete plus partial remission in 78%, with an in-breast pathologic complete response rate of 23% and an in-breast plus axilla pathologic complete response rate of 20%. In the multivariate analysis, only estrogen receptor (ER) status was significantly associated with pathologic complete response (odds ratio for ER negative, 5.77; 95% confidence interval, 3.49-9.52; P<0.0001). PTS induced a significant axillary downstaging (P<0.001), and breast sparing surgery was feasible in 65% versus 34% (P<0.001). CONCLUSIONS: Doxorubicin/paclitaxel-->CMF is feasible, safe, and well tolerated. Given as PST, it is markedly active, allowing for breast-sparing surgery in a large fraction of patients.
