RESUMO
PURPOSE: To investigate whether intensive follow-up (INT) after surgery for endometrial cancer impact health-related quality of life (HRQoL) and healthcare costs compared to minimalist follow-up (MIN), in the absence of evidence supporting any benefit on 5-year overall survival. METHODS: In the TOTEM trial, HRQoL was assessed using the SF-12 and the Psychological General Well-Being (PGWB) questionnaires at baseline, after 6 and 12 months and then annually up to 5 years of follow-up. Costs were analyzed after 4 years of follow-up from a National Health Service perspective, stratified by risk level. The probability of missing data was analyzed for both endpoints. RESULTS: 1847 patients were included in the analyses. The probability of missing data was not influenced by the study arms (MIN vs INT OR: 0.97 95%CI: 0.87-1.08). Longitudinal changes in HRQoL scores did not differ between the two follow-up regimens (MIN vs INT SF-12 PCS: -0.573, CI95%: -1.31; 0.16; SF-12 MCS: -0.243, CI95%: -1.08; 0.59; PGWB: -0.057, CI95%: -0,88; 0,77). The mean cost difference between the intensive and minimalist arm was 531 for low-risk patients and 683 for high-risk patients. CONCLUSION: In the follow-up of endometrial cancer after surgery, a minimalist treatment regimen did not affect quality of life and was cost-saving in both low-risk and high-risk recurrence patients. As previous results showed no survival benefit, a minimalist approach is justified. The relevant proportion of missing data on secondary outcomes of interest could be a critical point that deserves special attention.

PURPOSE: In the absence of clear evidence from randomized trials, the intensity of follow-up regimens after surgical treatment of endometrial cancer is highly variable in clinical practice. To reduce this uncertainty, we conducted a randomized trial to test whether an intensive (INT) versus a minimalist (MIN) follow-up regimen improves overall survival (OS) in patients undergoing operation for endometrial cancer. METHODS: The TOTEM study was a large, pragmatic randomized trial, conducted in 42 hospitals (in Italy and France) including patients surgically treated for endometrial cancer, in complete clinical remission, International Federation of Gynecology and Obstetrics stage I-IV. After stratification by center and risk of relapse (low or high), patients were randomly assigned (1:1) to INT or MIN hospital-based follow-up regimens. The study was powered to demonstrate an absolute improvement of 5% of the 5-year OS with the INT regimen. RESULTS: In total, 1,871 patients were randomly assigned between November 2008 and July 2018, and 1,847 patients (98.7%) were available for the final analysis (60% low risk). After a median follow-up of 69 months, the 5-year OS was 90.6% in the INT and 91.9% in the MIN arms (hazard ratio, 1.13, 95% CI, 0.86 to 1.50, P = .380). No differences in OS were found in subgroup analyses considering age, cancer treatment, risk of relapse, and degree of adherence of the center to the scheduled follow-up. The probability of detecting a relapse was slightly higher in the INT arm (hazard ratio, 1.17; 95% CI, 0.92 to 1.48; P = .194). CONCLUSION: An INT follow-up in endometrial cancer-treated patients does not improve OS, even in high-risk patients. According to available evidence, there is no need to routinely add vaginal cytology, laboratory, or imaging investigations to the MIN regimens used in this trial.

The frequency of thrombosis in AML has been evaluated only in a few studies and no validated predictive model is currently available. Recently, DIC score was shown to identify patients at higher thrombotic risk. We aimed to evaluate the frequency of thromboembolism in AML patients treated with intensive chemotherapy and to assess the ability of genetic and clinical factors to predict the thrombotic risk. We performed a retrospective observational study including 222 newly diagnosed adult AML (210) and high-risk MDS (12), treated with intensive chemotherapy between January 2013 and February 2020. With a median follow-up of 44 months, we observed 50 thrombotic events (90% were venous, VTE). The prevalence of thrombosis was 22.1% and the 6-months cumulative incidence of thrombosis was 10%. The median time to thrombosis was 84 days and 52% of the events occurred within 100 days from AML diagnosis. Khorana and DIC score failed to stratify patients according to their thrombotic risk. Only history of a thrombotic event (p = 0.043), particularly VTE (p = 0.0053), platelet count above 100 × 109/L at diagnosis (p = 0.036) and active smoking (p = 0.025) significantly and independently increased the risk of thrombosis, the latter particularly of arterial events. AML genetic profile did not affect thrombosis occurrence. Results were confirmed considering only thromboses occurring within day 100 from diagnosis. DIC score at diagnosis, but not thrombosis, was independently associated with reduced survival (p = 0.004). Previous VTE, platelet count above 100 × 109/L and active smoking were the only factors associate with increased thrombotic risk in AML patients treated intensively, but further studies are needed to validate these results.

INTRODUCTION: Testicular cancer is one of the most treatable cancers, with a 10-year survival of more than 95%. Many patients will be long-term survivors and this disease strikes men in an important phase of their lives, therefore the quality of life (QoL) among these patients is an area of particular interest. We aimed to study whether QoL in testicular cancer survivors depends on the time since cancer diagnosis. METHODS: Data were collected from the EPSAM (Esposizioni postnatali e salute maschile) study, a case-control study on patients with testicular cancer, diagnosed between 1997 and 2008 in the province of Turin, Northern Italy, and interviewed between 2008 and 2010 (response rate among cases 57%). Patients were contacted through their oncologist at the San Giovanni Batista Hospital in Turin or through their general practitioner (GP) in the rest of the Province of Turin. QoL was assessed cross-sectionally using the short form 12 (SF-12) questionnaire, a generic short-form health survey that produces two summary scores, PCS (physical component score) and MCS (mental component score), to evaluate physical and mental health, respectively. RESULTS: Out of 234 study patients, 125 cases were seminomas and 109 cases were nonseminomas. The mean age at diagnosis was 34.5 years. After adjusting for age, time since diagnosis was not associated with PCS and MCS scores. Among nonseminomas, the median PCS slightly increased (adjusted OR (odds ratio) for 5+ vs < 2 years since cancer diagnosis: 1.78 (1.17-2.73), p = 0.008) and MCS slightly decreased (adjusted OR per 1-year increase since cancer diagnosis: 0.92, 95% CI: 0.82-1.05, p = 0.23) with time. Similar findings of no association between time since diagnosis and PCS and MCS were found when the analyses were restricted to the subgroup of cancer patients contacted through their oncologist, whose response proportion was 82%. CONCLUSION: In a study of testicular cancer patients interviewed cross-sectionally at 1 to more than 10 years since diagnosis, time since cancer diagnosis was not associated with QoL when we considered all germ-cell testicular cancer patients together. When stratified by histology type, we found certain evidence that nonseminoma cases report higher PCS over time since cancer diagnosis.

BACKGROUND: Response shift (RS) has been defined as a change in the meaning of an individual's self-evaluation that needs to be accounted for when assessing longitudinal changes in health-related quality of life (HRQoL). RS detection through structural equation modeling is accomplished by adopting Oort's procedure based on a measurement model in which the observed variables are defined as reflective indicators of the HRQoL latent variable; that is, the latent variable causes the variation in the reflective indicators. This study aims to propose a procedure that assesses RS when formative indicators are used in measuring HRQoL; in this last case, the latent variable is considered to be a function of some formative indicators. A secondary aim is to compare the new procedure with Oort's procedure to highlight similarities and differences. METHODS: The data were retrieved from a consecutive series of 258 patients newly diagnosed with colorectal cancer and undergoing chemotherapy and/or surgery. The European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QOL-C30) was administered twice, once before and once six months after treatment. Structural equation modeling was used to evaluate RS and true change with the newly proposed method (in which fatigue and pain were defined as formative indicators) and with Oort's procedure (in which fatigue and pain were defined as reflective indicators). RESULTS: According to the new procedure, there was no measurement bias, and on average, patients' quality of life improved by 3.53 points (on a scale ranging from 0 to 100) at the 6-month follow-up. With Oort's procedure, the loading of the pain indicator was not invariant across the two time points, suggesting the presence of reprioritization, whereas the estimation of true change was very similar to the previous one: 3.87. CONCLUSIONS: RS and true change in HRQoL can be evaluated in the presence of formative indicators. Defining a measurement model by formative or reflective indicators can lead to different results.

Objectives: The aim of this study was to conduct a discrete choice experiment with patients affected by colorectal cancer to understand their preferences for different attributes of the chemotherapy supply. Our overall goal is to provide evidence on the relative importance of each attribute in order to tailor chemotherapy supply according to patients' priorities in the design or reorganization processes of cancer services.Methods: Focus groups were used to identify the attributes and levels for the discrete choice experiment. The attributes were: continuity of care, understanding, information, treatment choice, and time for therapy. Respondents were asked to choose between two mutually exclusive hypothetical alternatives of chemotherapy supply. Patients completed the discrete choice experiment along with the health-related quality of life and patients' satisfaction questions. Conditional and mixed logistic models were used to analyses the data.Results: Patients with colorectal cancer treated with chemotherapy (n = 76) completed the survey. The most important aspects of chemotherapy supply were: "Providing detailed and complete information" and "High ability in understanding" patients. Preferences were also influenced by the availability of a trusted doctor. Except for one attribute (waiting time for therapy), all other characteristics significantly influenced respondents' preferences.Conclusions: Results should support a policy of strengthening medical doctors' capabilities to communicate with patients, providing them complete information and involving them in the clinical decisions. Specifically, the findings should be used to improve the current provision of cancer care by identifying areas of preferred intervention from the perspectives of patients in order to tailor the service supply accordingly.

BACKGROUND: Retroperitoneal sarcomas (RPS) should be surgically managed in specialized sarcoma centers. However, it is not clearly demonstrated if clinical outcome is more influenced by Center Case Volume (CCV) or by Surgeon Case Volume (SCV). The aim of this study is to retrospectively explore the relationship between CCV and SCV and the quality of surgery in a wide region of Northern Italy. METHODS: We retrospectively collected data about patients M0 surgically treated for RPSs in 22 different hospitals from 2006 to 2011, dividing them in two hospital groups according to sarcoma clinical activity volume (HCV, high case volume or LCV, low case volume hospitals). The HCV group (> 100 sarcomas observed per year) included a Comprehensive Cancer Center (HVCCC) with a high sarcoma SCV (> 20 cases/year), and a Tertiary Academic Hospital (HVTCA) with multiple surgeon teams and a low sarcoma SCV (≤ 5 cases/year for each involved surgeon). All other hospitals were included in the LCV group (< 100 sarcomas observed per year). RESULTS: Data regarding 138 patients were collected. Patients coming from LCV hospitals (66) were excluded from the analysis as prognostic data were frequently not available. Among the 72 remaining cases of HCV hospitals 60% of cases had R0/R1 margins, with a more favorable distribution of R0/R1 versus R2 in HVCCC compared to HVTCA. CONCLUSIONS: In HCV hospitals, sarcoma SCV may significantly influence RPS treatment quality. In low-volume centers surgical reports can often miss important prognostic issues and surgical quality is generally poor.
RESUMO
BACKGROUND: It has been documented that variations exist in breast cancer treatment despite wide dissemination of clinical practice guidelines. The aim of this population-based study was to evaluate the impact of regional guidelines (Piedmont guidelines, PGL) for breast cancer diagnosis and treatment on quality-of-care indicators in the Northwestern Italian region of Piedmont. METHODS: We included two samples of women aged 50-69 years with incident breast cancer treated in Piedmont before and after the introduction of PGL: 600 in 2002 (pre-PGL) and 621 in 2004 (post-PGL). Patients were randomly selected among all incident breast cancer cases identified through the hospital discharge records database. We extracted clinical data on breast cancer cases from medical charts and ascertained vital status through linkage with town offices. We assessed compliance with 14 quality-of-care indicators from PGL recommendations, before and after their introduction in clinical practice. RESULTS: Among patients with invasive lesions, 77.1% (N = 368) and 77.5% (N = 383) in the pre-PGL and post-PGL groups, respectively, received breast conservative surgery (BCS) as a first-line treatment. Following BCS, 87.7% received radiotherapy in 2002, compared to 87.9% in 2004. Of all patients at medium-to-high risk of distant metastasis, 65.5% (N = 268) and 63.6% (N = 252) received chemotherapy in 2002 and in 2004, respectively. Among the 117 patients with invasive lesions and negative estrogen receptor status in 2002, hormonal therapy was prescribed in 23 of them (19.6%). The incorrect prescription of hormonal therapy decreased to 10.8% (N = 10) among the 92 estrogen receptor-negative patients in 2004 (p < 0.01).Compliance with PGL recommendations was already high in the pre-PGL group, although some quality-of-care indicators did not reach the standard. In the pre/post analysis, 8 out of 14 quality-of-care indicators showed an improvement from 2002 to 2004, but only 4 out of 14 reached statistical significance. We did not find any change in the risk of mortality in the post-PGL versus the pre-PGL group (adjusted hazard ratio 0.94, 95%CI 0.56-1.56). CONCLUSIONS: These results highlight the need to continue to improve breast cancer care and to measure adherence to PGL.

RATIONALE, AIMS AND OBJECTIVES: Lung cancer is a disease with high consumption of health care resources. The aim of this study was to describe hospital costs due to lung cancer care from diagnosis until death or end of the study follow-up, in a cohort of incident cases, by using administrative data. METHODS: Particular attention was given to the determinants of total costs and the impact of the initial treatment approach on the process of costs accumulation. Incident cases were identified by the local Cancer Registry (January 2000-December 2003) among the residents of Turin (Italy). Per patient hospital care has been determined from administrative databases (outpatient radiotherapy records and hospital discharge records). Costs determinants were identified via a multivariable generalized linear model (GLM), with a Gamma cost distribution and a logarithmic link function. To assess the time effect over the cost accumulation process for non-small-cell lung cancer cases, the same GLM Gamma model was repeated at different follow-up periods. Analyses were stratified by cancer histotype. RESULTS: Results evidenced the relevant role of initial patterns of care on the cost accumulation process, with increased midterm costs associated with curative patterns of care. CONCLUSION: The use of administrative data enabled hospital lung cancer care to be described, and related costs to be estimated.

OBJECTIVE: To analyze the role of sociodemographic factors as determinants of the initial pattern of care and survival in incident NSCLC cases. METHODS: We linked 2298 incident NSCLC cases, identified by the Piedmont Cancer Registry of Turin (PCRT) with administrative health records to identify the initial pattern of care. Because stage of disease strongly influences pattern of care and prognosis of NSCLC, all the analyses were stratified according to stage (early and advanced). The association between the set of patient's characteristics and the probability of accessing a specific pattern of care was analysed with a multivariable multinomial logistic regression model. Survival was analysed with the Cox proportional hazard model. RESULTS: In the early stage group, presence of comorbidities, older age and low educational level were all associated with a lower probability of receiving surgery. These same factors, as well as being unmarried, were associated with higher probability of receiving other non-curative care only. The effects of comorbidities and low educational level as barriers to receiving more effective patterns of care were not relevant in the advanced stage group. When controlling for initial patterns of care, in the early stage group, an age older than 75 years and being unmarried were negative prognostic factors, while survival was completely independent from educational level. Among patients with an advanced stage of disease, only comorbidities had a negative impact on survival. CONCLUSION: Appropriate lung cancer care is affected by sociodemographic factors. Greater attention to social and health programs is recommended to improve the timeliness of diagnosis, the staging of potentially resectable patients, and to implement more comprehensive multidisciplinary evaluations of those who may benefit from curative treatments.

OBJECTIVE: We have developed and validated an algorithm based on Piedmont hospital discharge abstracts for ascertainment of incident cases of breast, colorectal, and lung cancer. STUDY DESIGN AND SETTING: The algorithm training and validation sets were based on data from 2000 and 2001, respectively. The validation was carried out at an individual level by linkage of cases identified by the algorithm with cases in the Piedmont Cancer Registry diagnosed in 2001. RESULTS: The sensitivity of the algorithm was higher for lung cancer (80.8%) than for breast (76.7%) and colorectal (72.4%) cancers. The positive predictive values were 78.7%, 87.9%, and 92.6% for lung, colorectal, and breast cancer, respectively. The high values for colorectal and breast cancers were due to the model's ability to distinguish prevalent from incident cases and to the accuracy of surgery claims for case identification. CONCLUSIONS: Given its moderate sensitivity, this algorithm is not intended to replace cancer registration, but it is a valuable tool to investigate other aspects of cancer surveillance. This method provides a valid study base for timely monitoring cancer practice and related outcomes, geographic and temporal variations, and costs.

BACKGROUND AND PURPOSE: A survey was conducted of radiotherapy (RT) resources and utilization in a northwestern Italian Region in order to assess geographical variations in radiotherapy utilization rates, and the effects of infrastructure supply on accessibility. MATERIALS AND METHODS: The survey was conducted by analysing standardized utilization rates based on administrative records. The data were analysed at both Regional and Local Health Unit (LHU) level. RESULTS: Wide variation was found among LHUs RT utilization rates--the sex- and age-standardized rates varied from 1.8/1000 inhabitants to more than 3/1000 inhabitants. Patients resident in LHUs with no RT service showed a lower probability of accessing RT (standardized rate ratio (SRR), 0.82; 95%IC, 0.80-0.85). The utilization rate decreased in relation to the distance between a patient's residence and the nearest RT service; the reduction was greater for patients > or =70 years of age. CONCLUSION: The wide geographic variation implies lack of equity in access to services. Utilization levels decreased significantly with increasing distance from the nearest RT service, distance being a barrier to access particularly for older persons. The heterogeneous distribution of services on the Regional territory seems a relevant explanation of differences in utilization rates.

OBJECTIVE: Outpatient activity recording system has a potential role in clinical practice evaluation. Nevertheless, up to now, its utilisation has been limited by the paucity of its clinical data. This study describes a procedure for identifying the oncological diagnosis in patients receiving radiotherapy at an ambulatory service in the Piedmont Region. The procedure is based on the record linkage between discharge records (SDO) and outpatients records (PA), in order to obtain clinical information from the diagnosis related to possible admissions of the patients. METHODS: The study analyzed radiotherapy outpatients records in 2003 related to Piedmont residents and all discharge records in years 2000-2004. The quality of the procedure has been assessed by using the information on the real oncological diagnosis as reported in the outpatients medical records of a random sample of patients. RESULTS: The record linkage with SDO allows to define an oncological diagnosis for 82% (95% CI 78.5-84.8) of the patients. Agreement between defined diagnosis and the real one is 85.7% (CI 95% 82.2-88.6). The validity of the procedure is affected by the patients' cancer site. The distribution by cancer site of the patients treated with radiotherapy in Piedmont Region obtained with the record linkage procedure is homogeneous to the real distribution of the random sample used for control. CONCLUSIONS: Overall, the record linkage between SDO and radiotherapy PA shows a good performance in defining the oncological diagnosis of the patients receiving radiotherapy at an ambulatory setting. This method allows to increase interest and utility of PA records.
