RESUMO

PURPOSE: The time to deterioration (TTD) approach has been proposed as a modality of longitudinal analysis of patient-reported outcomes (PROs) in cancer randomized clinical trials (RCTs). The objective of this study was to perform a systematic review of how the TTD approach has been used in phase III RCTs to analyze longitudinal PRO data. METHODS: A systematic literature search was conducted in PubMed/MEDLINE, the Cochrane Library and through manual search to identify studies published between January 2014 and June 2018. All phase III cancer RCTs including a PRO endpoint using the TTD approach were considered. We collected general information about the study, PRO assessment and the TTD approach, such as the event definition, the choice of reference score and whether the deterioration was definitive or not. RESULTS: A total of 1549 articles were screened, and 39 studies were finally identified as relevant according to predefined criteria. Among these 39 studies, 36 (92.3%) were in advanced and/or metastatic cancer. Several different deterioration definitions were used in RCTs, 10 studies (25.6%) defined the deterioration as "definitive", corresponding to a deterioration maintained over time until the last PRO assessment available for each patient. The baseline score was explicitly stated as the reference score to qualify the deterioration for most studies (n = 31, 79.5%). CONCLUSION: This review highlights the lack of standardization of the TTD approach for the analysis of PRO data in RCTs. Special attention should be paid to the definition of "deterioration", and this should be based on the specific cancer setting.

RESUMO

Background: RAS mutations are currently sought for in tumor samples, which takes a median of almost 3 weeks in western European countries. This creates problems in clinical situations that require urgent treatment and for inclusion in therapeutic trials that need RAS status for randomization. Analysis of circulating tumor DNA might help to shorten the time required to determine RAS mutational status before anti-epidermal growth factor receptor antibody therapy for metastatic colorectal cancer. Here we compared plasma with tissue RAS analysis in a large prospective multicenter cohort. Patients and methods: Plasma samples were collected prospectively from chemotherapy-naive patients and analyzed centrally by next-generation sequencing (NGS) with the colon lung cancer V2 Ampliseq panel and by methylation digital PCR (WIF1 and NPY genes). Tumoral RAS status was determined locally, in parallel, according to routine practice. For a minimal κ coefficient of 0.7, reflecting acceptable concordance (precision ± 0.07), with an estimated 5% of non-exploitable data, 425 subjects were necessary. Results: From July 2015 to December 2016, 425 patients were enrolled. For the 412 patients with available paired plasma and tumor samples, the κ coefficient was 0.71 [95% confidence interval (CI), 0.64-0.77] and accuracy was 85.2% (95% CI, 81.4% to 88.5%). In the 329 patients with detectable ctDNA (at least one mutation or one methylated biomarker), the κ coefficient was 0.89 (95% CI, 0.84-0.94) and accuracy was 94.8% (95% CI, 91.9% to 97.0%). The absence of liver metastases was the main clinical factor associated with inconclusive circulating tumor DNA results [odds ratio = 0.11 (95% CI, 0.06-0.21)]. In patients with liver metastases, accuracy was 93.5% with NGS alone and 97% with NGS plus the methylated biomarkers. Conclusion: This prospective trial demonstrates excellent concordance between RAS status in plasma and tumor tissue from patients with colorectal cancer and liver metastases, thus validating plasma testing for routine RAS mutation analysis in these patients. Clinical Trial registration: Clinicaltrials.gov, NCT02502656.

RESUMO

Advances in cancer care delivery require revision and further development of questionnaires assessing patients' perceived quality of care. This study pre-tested the revised EORTC satisfaction with cancer care core questionnaire applicable in both the cancer inpatient and outpatient settings, and its new, outpatient-specific complementary module. The process of revision, development of the extended application, and pre-testing of these questionnaires was based on phases I to III of the "EORTC Quality of Life Group Module Development Guidelines." In phase III, patients in 11 countries in four European regions, South America and Asia completed provisional versions of the questionnaires. Fifty-seven relevant issues selected from literature reviews and input from experts were operationalized into provisional items, and subsequently translated into ten languages. Assessment of understanding, acceptability, redundancy and relevance by patients (n = 151) from oncology inpatient wards, and outpatient chemotherapy, radiotherapy and consultation settings, led to retention of, deletion of and merging of 40, 14 and 6 items respectively. Cronbach's alpha coefficients for hypothesized questionnaire scales were above 0.80. Our results provide preliminary support for the 33-item EORTC Satisfaction with cancer care core questionnaire and the 7-item complementary module specific for the outpatient care setting. A large scale phase IV cross-cultural psychometric study is now underway.

RESUMO

BACKGROUND: To assess the efficacy of a patient educational program built according to guidelines that aims at reducing cancer-related fatigue (CRF). METHODS: Randomised controlled trial, multicentre, comparing a patient education program, vs the standard of care. Patients were adult cancer outpatients with any tumour site. The primary outcome was fatigue severity assessed with a visual analogical scale (VAS), between the day of randomisation and week 7. Secondary outcomes were fatigue assessed with other scales, health-related quality of life, anxiety and depression. The time to fatigue severity deterioration was assessed. Analyses were performed in a modified intent-to-treat way, that is, including all patients with at least one baseline and 1 week 7 score. RESULTS: A total of 212 patients were included. Fatigue severity assessment was made on 79 patients in the experimental group and 65 in the control group. Between randomisation and week 7, the fatigue (VAS) improved by 0.96 (2.85) points in the experimental group vs 1.63 (2.63) points in the control group (P=0.15). No differences with the secondary outcomes were highlighted between two groups. No other factors were found to be associated with fatigue severity deterioration. CONCLUSIONS: Despite rigorous methodology, this study failed to highlight the program efficacy in fatigue reduction for cancer patients. Other assessment tools should be developed to measure the effect of the program on CRF and behaviour. The implementation of the program should also be explored in order to identify its mechanisms and longer-term impact.

RESUMO

Since the MOSAIC study, oxaliplatin-based adjuvant chemotherapy has been the standard treatment of stage III colon cancer. Combination therapy with fluoropyrimidines and oxaliplatin has improved overall survival (OS) and reduced the risk of recurrence in patients with resected stage III colon cancer. However, only 20% of patients really benefit from adjuvant chemotherapy, exposing 80% of patients to unnecessary toxicity. Recent analyses of large multicenter adjuvant studies have focused on the prognostication of OS and disease-free survival in stage III colon cancer in order to reduce over-treatment and to find more accurate prognostic tools than those used for adjuvant treatment decision-making in stage II disease. Indeed, clinical and pathological prognostic factors, although important, are not sufficient to decide which stage III patients will benefit from adjuvant therapy, and biomarkers will help select patient that need adjuvant treatment. Molecular markers such as microsatellite status and BRAF and KRAS mutations have recently been explored, and molecular signatures have been identified as promising prognostic factor for OS. Furthermore, recent studies have highlighted the prognostic value of immune infiltration. This review focuses on pathologic, immunologic and molecular prognostic markers for stage III colon cancer that could help clinicians tailor adjuvant treatment in a comprehensive transversal approach.

RESUMO

Traditionally, the efficacy of cancer treatment in patients with advance or metastatic disease in clinical studies has been studied using overall survival and more recently tumor-based end points such as progression-free survival, measurements of response to treatment. However, these seem not to be the relevant clinical end points in current situation if such end points were no validated as surrogate of overall survival to demonstrate the clinical efficacy. Appropriate, meaningful, primary patient-oriented and patient-reported end points that adequately measure the effects of new therapeutic interventions are then crucial for the advancement of clinical research in metastatic colorectal cancer to complement the results of tumor-based end points. Health-related quality of life (HRQoL) is effectively an evaluation of quality of life and its relationship with health over time. HRQoL includes the patient report at least of the way a disease or its treatment affects its physical, emotional and social well-being. Over the past few years, several phase III trials in a variety of solid cancers have assessed the incremental value of HRQoL in addition to the traditional end points of tumor response and survival results. HRQoL could provide not only complementary clinical data to the primary outcomes, but also more precise predictive and prognostic value. This end point is useful for both clinicians and patients in order to achieve the dogma of precision medicine. The present article examines the use of HRQoL in phase III metastatic colorectal cancer clinical trials, outlines the importance of HRQoL assessment methods, analysis, and results presentation. Moreover, it discusses the relevance of including HRQoL as a primary/co-primary end point to support the progression-free survival results and to assess efficacy of treatment in the advanced disease setting.

RESUMO

This qualitative study aimed to explore cancer patients' perceived tolerance of side effects in phase I drug trials. Patients with solid tumours receiving molecularly targeted agents with/without chemotherapy were eligible for inclusion. In-depth semi-structured interviews were carried out with 17 patients with a median [range] age of 63 [41-72] years. Treatment was discontinued in seven patients. Verbatim transcripts of the audio-taped interviews were analysed using a constructivist grounded theory approach. Four conceptual categories emerged from data analysis, labelled "suffering from side effects" comprising a range of symptoms, psychosocial or role disturbances; "striving to cope with side effects" reflecting psychological strategies for managing side effects; "hoping" reflecting expectations about treatment efficacy and relief from side effects; and "appraisal of care." Among patients remaining in the trial, treatment was currently perceived as fairly tolerable. For most respondents, whether still in a trial or not, treatment discontinuation could not be justified by the non-tolerance of treatment side effects. These results question the adequacy of patient-perceived tolerance reports to determine an optimal drug dose for phase II trials. Confronted with patients' hopes and inappropriate beliefs, communication is challenging in phase I trials and could benefit from facilitating psychosocial interventions.

RESUMO

BACKGROUND: Evaluate the aesthetic clinical results, satisfaction and quality of life related to health in patients who underwent breast reconstruction by exclusive lipofilling or in addition to other surgical techniques. MEANS AND METHODS: A retrospective observational study was carried between 2009 and 2014 in four groups of patients who underwent a lipofilling by the same operator either after a conservative treatment (group 1), or exclusively (group 2), or after a flap (group 3) or implants (group 4). The sociodemographic data related to lipofilling or tumor pathology were collected and reported in a software designed for this study. Satisfaction and quality of life after lipofilling was assessed using the questionnaire Q BREAST(©) postoperative reconstruction module. RESULTS: One hundred and seventy lipofilling procedures were performed in 68 patients. The average volume transferred was 1421.2cm(3) for the exclusive lipofilling group and the average number of sessions was 4.9 spread over a period of 15.6months on average. In adjuvant technique or conservative surgery, the average total volume transferred was 212.2cm(3) and the average number of sessions was 1.4. The abdomen was the site most used donor and the posterior thigh exclusively used in exclusive reconstruction. The cytosteatonecrosis rate was 8.8 % (n=6). A single case of infection was noted. The tumor recurrence at ten months after lipofilling concerned two patients. The response rate was 80.8 %. The lipofilling improves the final cosmetic result with a rate of 91.1 % of patients satisfied or very satisfied with their breast. In all, 95.4 % of patients in the exclusive lipofilling group found a secondary benefit after surgery. Quality of life after lipofilling is also improved socially and sexually in the four groups with better results in patients who underwent conservative treatment. CONCLUSION: The lipofilling is a simple, reliable technique, requiring a learning curve, improving the final aesthetic result and the quality of life it is used exclusively or to complement other techniques.

RESUMO

OBJECTIVES: We conducted a prospective study approved by the local ethics committee to determine the impact of a pharmaceutical intervention (PI) on pain, fatigue, quality of life (QoL) and coping strategies in patients with HMs starting chemotherapy sessions. MATERIAL AND METHODS: Patients received either usual care (UC)+PI (PI group) or UC alone (UC group). They had to complete 2 questionnaires, QLQ-C30 and MAC 21, at 3 different time points: before starting the 1st chemotherapy session (T1), during the intercure (T2) and the day before starting the 2nd chemotherapy session (T3). To determine predictive factors of pain, fatigue, QoL and coping scores at T3, a multivariate ANOVA was used. QoL and coping scores were analysed longitudinally using a linear mixed model. RESULTS: Sixty-eight patients were included in the PI (n=34) or UC groups (n=34). Ninety-two percent of the patients returned all the questionnaires. At inclusion, QoL was significantly better in the PI group (P=0.047). At T3, the group had no influence on pain, fatigue, nor coping scores but a trend towards a better QoL was observed in the PI group (P=0.090). Longitudinally, the PI group did not present significantly better scores on pain, fatigue but both a trend toward better Qol scores and lower anxious preoccupations scores. CONCLUSION: A PI at the beginning of chemotherapy sessions did not have any significant impact on pain and fatigue but a trend towards better Qol scores and lower anxious preoccupations scores.

RESUMO

BACKGROUND: Perioperative FOLFOX4 (oxaliplatin plus 5-fluorouracil/leucovorin) chemotherapy is the current standard in patients with resectable metastases from colorectal cancer (CRC). We aimed to determine whether a sequential chemotherapy with dose-dense oxaliplatin (FOLFOX7) and irinotecan (FOLFIRI; irinotecan plus 5-fluorouracil/leucovorin) is superior to FOLFOX4. The chemotherapy timing was not imposed, and was perioperative or postoperative. PATIENTS AND METHODS: In this open-label, phase III trial, patients with resectable or resected metastases were randomly assigned either to 12 cycles of FOLFOX4 (oxaliplatin 85 mg/m(2)) or 6 cycles of FOLFOX7 (oxaliplatin 130 mg/m(2)) followed by 6 cycles of FOLFIRI (irinotecan 180 mg/m(2)). Randomization was done centrally, with stratification by chemotherapy timing, type of local treatment (surgery versus radiofrequency ablation with/without surgery), and Fong's prognostic score. The primary end point was 2-year disease-free survival (DFS). RESULTS: A total of 284 patients were randomized, 142 in each treatment group. Chemotherapy was perioperative in 168 (59.2%) patients and postoperative in 116 (40.8%) patients. Perioperative chemotherapy was preferentially proposed for synchronous metastases, whereas postoperative chemotherapy was more frequently used for metachronous metastases. Two-year DFS was 48.5% in the FOLFOX4 group and 50.0% in the FOLFOX7-FOLFIRI group. In the multivariable analysis, more than one metastasis [hazard ratio (HR) = 2.15] and synchronous metastases (HR = 1.63) were independent prognostic factors for shorter DFS. Five-year overall survival (OS) rate was 69.5% with FOLFOX4 versus 66.6% with FOLFOX7-FOLFIRI. CONCLUSIONS: FOLFOX7-FOLFIRI is not superior to FOLFOX4 in patients with resectable metastatic CRC. Five-year OS rates observed in both groups are the highest ever reported in this setting, possibly reflecting the pragmatic approach to chemotherapy timing. CLINICAL TRIALS NUMBER: NCT00268398.

RESUMO

BACKGROUND: In clinical trials, the use of intermediate time-to-event end points (TEEs) is increasingly common, yet their choice and definitions are not standardized. This limits the usefulness for comparing treatment effects between studies. The aim of the DATECAN Kidney project is to clarify and recommend definitions of TEE in renal cell cancer (RCC) through a formal consensus method for end point definitions. MATERIALS AND METHODS: A formal modified Delphi method was used for establishing consensus. From a 2006-2009 literature review, the Steering Committee (SC) selected 9 TEE and 15 events in the nonmetastatic (NM) and metastatic/advanced (MA) RCC disease settings. Events were scored on the range of 1 (totally disagree to include) to 9 (totally agree to include) in the definition of each end point. Rating Committee (RC) experts were contacted for the scoring rounds. From these results, final recommendations were established for selecting pertinent end points and the associated events. RESULTS: Thirty-four experts scored 121 events for 9 end points. Consensus was reached for 31%, 43% and 85% events during the first, second and third rounds, respectively. The expert recommend the use of three and two endpoints in NM and MA setting, respectively. In the NM setting: disease-free survival (contralateral RCC, appearance of metastases, local or regional recurrence, death from RCC or protocol treatment), metastasis-free survival (appearance of metastases, regional recurrence, death from RCC); and local-regional-free survival (local or regional recurrence, death from RCC). In the MA setting: kidney cancer-specific survival (death from RCC or protocol treatment) and progression-free survival (death from RCC, local, regional, or metastatic progression). CONCLUSIONS: The consensus method revealed that intermediate end points have not been well defined, because all of the selected end points had at least one event definition for which no consensus was obtained. These clarified definitions of TEE should become standard practice in all RCC clinical trials, thus facilitating reporting and increasing precision in between trial comparisons.

RESUMO

BACKGROUND: The use of potential surrogate end points for overall survival, such as disease-free survival (DFS) or time-to-treatment failure (TTF) is increasingly common in randomized controlled trials (RCTs) in cancer. However, the definition of time-to-event (TTE) end points is rarely precise and lacks uniformity across trials. End point definition can impact trial results by affecting estimation of treatment effect and statistical power. The DATECAN initiative (Definition for the Assessment of Time-to-event End points in CANcer trials) aims to provide recommendations for definitions of TTE end points. We report guidelines for RCT in sarcomas and gastrointestinal stromal tumors (GIST). METHODS: We first carried out a literature review to identify TTE end points (primary or secondary) reported in publications of RCT. An international multidisciplinary panel of experts proposed recommendations for the definitions of these end points. Recommendations were developed through a validated consensus method formalizing the degree of agreement among experts. RESULTS: Recommended guidelines for the definition of TTE end points commonly used in RCT for sarcomas and GIST are provided for adjuvant and metastatic settings, including DFS, TTF, time to progression and others. CONCLUSION: Use of standardized definitions should facilitate comparison of trials' results, and improve the quality of trial design and reporting. These guidelines could be of particular interest to research scientists involved in the design, conduct, reporting or assessment of RCT such as investigators, statisticians, reviewers, editors or regulatory authorities.

RESUMO

BACKGROUND: Using surrogate end points for overall survival, such as disease-free survival, is increasingly common in randomized controlled trials. However, the definitions of several of these time-to-event (TTE) end points are imprecisely which limits interpretation and cross-trial comparisons. The estimation of treatment effects may be directly affected by the definitions of end points. The DATECAN initiative (Definition for the Assessment of Time-to-event Endpoints in CANcer trials) aims to provide recommendations for definitions of TTE end points. We report guidelines for randomized cancer clinical trials (RCTs) in breast cancer. PATIENTS AND METHODS: A literature review was carried out to identify TTE end points (primary or secondary) reported in publications of randomized trials or guidelines. An international multidisciplinary panel of experts proposed recommendations for the definitions of these end points based on a validated consensus method that formalize the degree of agreement among experts. RESULTS: Recommended guidelines for the definitions of TTE end points commonly used in RCTs for breast cancer are provided for non-metastatic and metastatic settings. CONCLUSION: The use of standardized definitions should facilitate comparisons of trial results and improve the quality of trial design and reporting. These guidelines could be of particular interest to those involved in the design, conducting, reporting, or assessment of RCT.

RESUMO

BACKGROUND: Prognosis of unresectable glioblastoma (GB) remains poor, despite temozolomide (TMZ)-based chemoradiation. Activity of bevacizumab (BEV) and irinotecan (IRI) has been reported in recurrent disease. We evaluated BEV and IRI as neo-adjuvant and adjuvant treatment combined with TMZ-based chemoradiation for unresectable GB. PATIENTS AND METHODS: Patients with unresectable GB, age 18-70, IK ≥50 were eligible. The experimental arm (BEV/IRI) consisted of neo-adjuvant intravenous BEV, 10 mg/kg, and IRI, 125 mg/m(2), every 2 weeks for four cycles before radiotherapy (RT) (60 Gy), concomitant oral TMZ, 75 mg/m(2)/day, and BEV, 10 mg/kg every 2 weeks. Adjuvant BEV and IRI were given every 2 weeks for 6 months. The control arm consisted of concomitant oral TMZ, 75 mg/m(2)/day during RT, and 150-200 mg/m(2) for 5 days every 28 days for 6 months. The use of BEV was allowed at progression in the control arm. RESULTS: Patients (120) were included from April 2009 to January 2011. The working hypothesis was that treatment would increase the progression-free survival at 6 month (PFS-6) from 50% to 66%. The primary objective was not achieved, and only 30 out of 60 patients were alive without progression at 6 months (50.0% [IC95% (36.8; 63.1)] in the BEV/IRI arm when 37 out of 60 patients were required according to the Fleming decision rules. PFS-6 was 7.1 months in BEV/IRI versus 5.2 months in the control arm. The median overall survival was not different between the two arms (11.1 months). Main toxicities were three fatal intracranial bleedings, three bile duct or digestive perforations/infections (1 fatal), and six thrombotic episodes in the BEV/IRI arm, whereas there was one intracranial bleeding, two bile duct or digestive perforations/infections (1 fatal), and one thrombotic episode in the control arm. CONCLUSIONS: Neo-adjuvant and adjuvant BEV/IRI, combined with TMZ-radiation, is not recommended for further evaluation in the first-line treatment of unresectable GB. CLINICAL TRIAL REGISTRATION: Clinical trial registered under EUDRACT number 2008-002775-28 (NCT01022918).

RESUMO

BACKGROUND: Small bowel adenocarcinoma (SBA) is a rare tumour with a poor prognosis. Molecular biology data on SBA carcinogenesis are lacking. METHODS: Expression of HER2, ß-catenin, p53 and mismatch repair (MMR) protein was assessed by immunohistochemistry. KRAS, V600E BRAF mutations and microsatellite instability were investigated. RESULTS: We obtained samples from 63 SBA patients (tumour stages: I-II: 30%; III: 35%; IV: 32%; locally advanced: 3%). HER2 overexpression (3+) was observed in 2 out of 62 patients, overexpression of p53 in 26 out of 62, abnormal expression of ß-catenin in 12 out of 61, KRAS mutation in 21 out of 49, BRAF V600E mutation in 1 out of 40 patients, MMR deficiency (dMMR) in 14 out of 61 and was consistent with Lynch syndrome in 9 out of 14 patients. All of the dMMR tumours were in the duodenum or jejunum and only one was stage IV. Median overall survival (OS) was 36.6 months (95% CI, 26.9-72.2). For all patients, in univariate analysis, stages I-II (P<0.001), WHO PS 0-1 (P=0.01) and dMMR phenotype (P=0.02) were significantly associated with longer OS. In multivariate analysis, disease stage (P=0.01) and WHO PS 0-1 (P=0.001) independently predicted longer OS. For stage IV patients, median OS was 20.5 months (95% CI: 14.6; 36.6 months). In multivariate analysis, WHO PS 0-1 (P=0.0001) and mutated KRAS status (P=0.02) independently predicted longer OS. CONCLUSION: This large study suggests that molecular alterations in SBA are closer to those in colorectal cancer (CRC) than those in gastric cancer, with low levels of HER 2 overexpression and high frequencies of KRAS mutations. The seemingly higher frequency of dMMR than in CRC may be explained by the higher frequency of Lynch syndrome in SBA patients. A dMMR phenotype was significantly associated with a non-metastatic tumour (P=0.02). A trend for a good prognosis and a duodenum or jejunum primary site was associated with dMMR.

RESUMO

BACKGROUND: Older people represent the majority of cancer patients but their specific needs are often ignored in the development of health-related quality of life (HRQOL) instruments. The European Organisation for Research and Treatment of Cancer (EORTC) QLQ-ELD15 was developed to supplement the EORTC's core questionnaire, the QLQ-C30, for measuring HRQOL in patients aged >70 years in oncology studies. METHODS: Patients (n=518) from 10 countries completed the QLQ-C30, QLQ-ELD15 and a debriefing interview. Eighty two clinically stable patients repeated the questionnaires 1 week later (test-retest analysis) and 107 others, with an expected change in clinical status, repeated the questionnaires 3 months later (response to change analysis, RCA). RESULTS: Information from the debriefing interview, factor analysis and item response theory analysis resulted in the removal of one item (QLQ-ELD15QLQ-ELD14) and revision of the proposed scale structure to five scales (mobility, worries about others, future worries, maintaining purpose and illness burden) and two single items (joint stiffness and family support). Convergent validity was good. In known-group comparisons, the QLQ-ELD14 differentiated between patients with different disease stage, treatment intention, number of comorbidities, performance status and geriatric screening scores. Test-retest and RCA analyses were equivocal. CONCLUSION: The QLQ-ELD14 is a validated HRQOL questionnaire for cancer patients aged 70 years. Changes in elderly patients' self-reported HRQOL may be related to both cancer evolution and non-clinical events.

RESUMO

BACKGROUND: The aim of this study was to assess long-term quality of life (QoL) over a period of 6 years in women with breast cancer (BC) who underwent sentinel lymph node biopsy (SLNB), axillary lymph node dissection (ALND), or SLNB followed by ALND. METHODS: The European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC-QLQ)-C30 and the EORTC-QLQ-BR-23 questionnaires were used to assess QoL before surgery, just after surgery, 6, 12 and 72 months later. The longitudinal effect of surgical modalities on QoL was assessed with a mixed model analysis of variance for repeated measurements. RESULTS: Five hundred and eighteen BC patients were initially included. The median follow-up was 6 years. During the follow-up, 61 patients died. None of the patients of the SLNB group developed lymphedema during follow-up and the relapse rate was similar in the different groups (P=0.62). Before surgery, global health status (P=0.52) and arm symptoms (BRAS) (P=0.99) QoL scores were similar whatever the surgical procedure. The BRAS score (P=0.0001) was better in the SLNB group 72 months after surgery. Moreover, during follow-up, patients treated with SLNB had lower arm symptoms scores than ALND patients and there was no difference for arm symptoms between patients treated with ALND and those treated with SLNB followed by complementary ALND. CONCLUSION: Long-term follow-up showed that SLNB was associated with less morbidity than ALND.

RESUMO

BACKGROUND: Squamous cell carcinoma of the anal canal (SCCA) is a rare disease, mostly diagnosed at early stage. After concurrent chemoradiation (CRT) with mitomycin C and 5-fluorouracil (5FU), local or metastatic recurrences occur in >20% of the patients. After treatment failure, cisplatin (CDDP)-based chemotherapy is the standard option, but complete response (CR) is a rare event and the prognosis remains poor. PATIENTS AND METHODS: Eight consecutive patients with advanced recurrent SCCA after CRT were treated with DCF regimen (docetaxel 75 mg/m(2) day 1, CDDP 75 mg/m(2) day 1 and 5FU at 750 mg/m(2)/day for 5 days every 3 weeks). Tumour samples were analysed for human papillomavirus (HPV) genotyping, as well as p16 and p53 expression. RESULTS: After a median follow-up of 41 months, the overall survival rate at 12 months was 62.5% (95% CI 22.9-86.1 months). Four patients achieved a complete remission and remain relapse-free at the time of analysis with a progression-free survival of 19, 33, 43 and 88 months. Three of these patients underwent surgery for all involved metastatic sites. For all of them, pathological CR was confirmed. DCF regimen appeared feasible in these patients previously exposed to pelvic CRT, and no grade IV toxicity occurred. All patients in complete remission had HPV-16-positive SCCA, while HPV could only be detected among 50% of the non-responding patients. Of interest, immunohistochemical study revealed a p16(+)/p53(-) phenotype in these patients, while none of non-responders expressed p16. CONCLUSION: The high level of complete and long-lasting remission among SCCA patients treated with DCF regimen supports the assessment of this strategy in prospective cohorts.

RESUMO

PURPOSE: To characterize response shift effects in patients with breast cancer (BC). METHODS: The QLQ-C30, BR23, and EurQOL-EQ-5D were assessed at baseline and at the end of the first hospitalization. We used the then-test approach to characterize changes in internal standards by calculating the mean difference between the then-test (retrospective measure) and pre-test baseline QoL assessments. The Ideal Scale Approach was also used to assess changes in standards by comparing health and QoL expectancies between baseline and the end of the first hospitalization. Successive Comparison Approach was used to assess changes in values through the longitudinal assessment of the relative importance of EuroQOL dimensions. RESULTS: The results of this study showed that recalibration RS effects occurred early after the first hospitalization for 6/15 dimensions of QLQ-C30 (emotional, cognitive, fatigue, insomnia, appetite loss, diarrhea) and 2/8 of BR-23 (future perspective, systemic therapy side effects). Moreover, health and QoL expectancies changed between the baseline and the end of the first hospitalization, and changes in values were seen for the self-care and usual activities dimensions of the EuroQOL-EQ-5D. CONCLUSIONS: The occurrence of RS early after the first hospitalization suggests that it needs to be taken into account to interpret QoL changes in BC.

RESUMO

This population-based study aimed to describe the effects of neoadjuvant chemotherapy (NC) on survival in breast cancer (BC) patients in daily practice. BC patients treated with NC followed by surgery and radiotherapy, were retrospectively selected from 1982 to 2005 using the Côte d'Or BC registry. These patients were matched for the baseline AJCC (American Joint Committee on Cancer) stage, age at diagnosis, date of diagnosis and oestrogens receptors status to those who had undergone surgery followed by adjuvant chemotherapy and radiotherapy. The prognostic effect of NC on survival in BC patients was assessed with relative survival (RS) analyses. From 1982 to 2005, 210 patients with BC diagnosed in Côte d'Or were treated with NC followed by surgery and radiotherapy. For these patients, mean age at diagnosis was 50 (SD = 11). The main tumour characteristics were clinical AJCC stage 3 (46%) and an advanced Scarff Bloom and Richardson (SBR) stage (80%). Breast conserving surgery was performed in 84 patients (40%), 151 patients (72%) were treated with anthracyclines as the NC and the 5-year RS rate was 71%. Among these patients, 92 (37%) were matched. In this population, multivariate analyses showed that the use of NC did not independently influence RS: relative excess risk = 0.93 (0.50, 1.71).
