[Show abstract][Hide abstract] ABSTRACT: The occurrence of response shift (RS) in longitudinal health-related quality of life (HRQoL) studies, reflecting patient adaptation to disease, has already been demonstrated. Several methods have been developed to detect the three different types of response shift (RS), i.e. recalibration RS, 2) reprioritization RS, and 3) reconceptualization RS. We investigated two complementary methods that characterize the occurrence of RS: factor analysis, comprising Principal Component Analysis (PCA) and Multiple Correspondence Analysis (MCA), and a method of Item Response Theory (IRT).
Breast cancer patients (n = 381) completed the EORTC QLQ-C30 and EORTC QLQ-BR23 questionnaires at baseline, immediately following surgery, and three and six months after surgery, according to the "then-test/post-test" design. Recalibration was explored using MCA and a model of IRT, called the Linear Logistic Model with Relaxed Assumptions (LLRA) using the then-test method. Principal Component Analysis (PCA) was used to explore reconceptualization and reprioritization.
MCA highlighted the main profiles of recalibration: patients with high HRQoL level report a slightly worse HRQoL level retrospectively and vice versa. The LLRA model indicated a downward or upward recalibration for each dimension. At six months, the recalibration effect was statistically significant for 11/22 dimensions of the QLQ-C30 and BR23 according to the LLRA model (p <= 0.001). Regarding the QLQ-C30, PCA indicated a reprioritization of symptom scales and reconceptualization via an increased correlation between functional scales.
Our findings demonstrate the usefulness of these analyses in characterizing the occurrence of RS. MCA and IRT model had convergent results with then-test method to characterize recalibration component of RS. PCA is an indirect method in investigating the reprioritization and reconceptualization components of RS.

Breast cancer in men in Cote d'Or (France): epidemiological characteristics, treatments and prognostic factors
Breast cancer in men is rare, and clinical trials are thus not feasible. This study aimed to describe the epidemiological characteristics, treatment and prognostic factors of breast cancer in men. A population-based study was performed using data from the Cote d'Or breast and gynaecological cancer registry. Data on male breast cancer diagnosed from 1982 to 2008 were provided. Relative survival rates were estimated at 5 years according to the characteristics of the patient and tumour, and treatment. Prognostic factors of survival in men with breast cancer were identified using a generalised linear model. Seventy-five men with invasive breast cancer were registered. Mean age at diagnosis was 66 years. The use of adjuvant chemotherapy (P= 0.013) and hormone therapy (P < 0.0001) increased over time. Relative survival rate at 5 years was 69% for the whole population. Analysis of relative survival according to the treatment showed that survival was longer for patients treated with surgery + radiotherapy + hormone therapy: 89% at 5 years. Scarff, Bloom and Richardson grade was independent prognostic factor of survival. Male breast cancer is a rare disease with a poor prognosis, and diagnosis is often made at an advanced stage. Early diagnosis and better knowledge of the disease would certainly lead to improvements in the prognosis.

[Show abstract][Hide abstract] ABSTRACT: The purpose of this prospective multicenter study was to assess one-step nucleic acid amplification (OSNA) for intraoperative sentinel lymph node (SLN) metastasis detection in breast cancer patients, using final histology as the reference standard. OSNA results were also compared to intraoperative histology SLN evaluation and to standard clinicopathological risk markers. For this study, fresh SLNs were cut in four blocks, and alternate blocks were used for OSNA and histology. CK19 mRNA copy number was categorized as strongly positive, positive or negative. Positive histology was defined as presence of macrometastasis or micrometastasis. When discrepancies occurred, the entire SLNs were subjected to histological studies and the node lysates to additional molecular studies. Five hundred three SLN samples from 233 patients were studied. Mean time to evaluate two SLNs was 40 min. Sensitivity per patient was 91.4% (95% CI, 76.9-98.2%), specificity 93.3% (95% CI, 88.6-96.6%), positive likelihood ratio 13.7 and negative likelihood ratio 0.1. Sensitivity was 63.6% for frozen sections and 47.1% for touch imprint cytology. Both methods were 100% specific. Positive histology and positive OSNA were significantly associated with highest clinical stage, N1 status and vascular invasion; and OSNA results correlated with HER2/neu status and benefited patients with negative histology. These findings show that OSNA assay can allow detection of SLN metastasis in breast cancer patients intraoperatively with a good sensitivity, thus minimizing the need for second surgeries for axillary lymph node detection.

[Show abstract][Hide abstract] ABSTRACT: 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.

[Show abstract][Hide abstract] ABSTRACT: This prospective multicenter study explored different definitions of time to deterioration (TTD) in quality of life (QoL) scores, according to different cutoffs of the minimal clinically important difference (MCID) as a modality for longitudinal QoL assessment in breast cancer patients.
QoL was assessed using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire C30 and BR-23 before surgery, after surgery, and 6 and 12 months later. The global health score, arm symptoms score (BRAS), and breast symptoms score were analyzed. For a given baseline score, QoL was considered to have deteriorated if this score decreased by ≥5 points at any time point after baseline. Analyses were repeated using an MCID of 10 points and taking the score after surgery as the reference score (to explore the occurrence of response shift). TTD was calculated using the Kaplan-Meier method and Cox regression was used to identify independent factors associated with TTD.
Two hundred thirty-five patients underwent axillary lymph node dissection (ALND), 222 underwent sentinel lymph node biopsy (SLNB), and 61 underwent SLNB plus ALND. Patients who underwent SLNB had a significantly longer TTD for the BRAS dimension than those who underwent ALND. Cox multivariate analyses showed that treatment using SLNB and age >59 years were independently associated with longer TTD for the BRAS, whereas surgery elsewhere than at the Centre Georges François Leclerc was associated with a shorter TTD.
Exploration of different definitions of TTD in QoL provides meaningful longitudinal QoL results for clinicians.
[Show abstract][Hide abstract] ABSTRACT: Our objective was to assess the global cost of the sentinel lymph node detection [axillary sentinel lymph node detection (ASLND)] compared with standard axillary lymphadenectomy [axillary lymph node dissection (ALND)] for early breast cancer patients.
We conducted a prospective, multi-institutional, observational, cost comparative analysis. Cost calculations were realized with the micro-costing method from the diagnosis until 1 month after the last surgery.
Eight hundred and thirty nine patients were included in the ASLND group and 146 in the ALND group. The cost generated for a patient with an ASLND, with one preoperative scintigraphy, a combined method for sentinel node detection, an intraoperative pathological analysis without lymphadenectomy, was lower than the cost generated for a patient with lymphadenectomy [€ 2947 (σ = 580) versus € 3331 (σ = 902); P = 0.0001].
ASLND, involving expensive techniques, was finally less expensive than ALND. The length of hospital stay was the cost driver of these procedures. The current observational study points the heterogeneous practices for this validated and largely diffused technique. Several technical choices have an impact on the cost of ASLND, as intraoperative analysis allowing to reduce rehospitalization rate for secondary lymphadenectomy or preoperative scintigraphy, suggesting possible savings on hospital resources.

[Show abstract][Hide abstract] ABSTRACT: The standard management for advanced-stage epithelial ovarian cancer is optimum cytoreductive surgery followed by platinum based chemotherapy. However, retroperitoneal lymph node resection remains controversial. The multiple directions of the lymph drainage pathway in ovarian cancer have been recognized. The incidence and pattern of lymph node involvement depends on the extent of the disease and the histological type. Several published cohorts suggest the survival benefit of pelvic and para-aortic lymphadenectomy. A recent large randomized trial have demonstrated the potential benefit for surgical removal of bulky lymph nodes in term of progression-free survival but failed to show any overall survival benefit because of a critical methodology. Further randomised trials are needed to balance risks and benefits of systematic lymphadenectomy in advanced-stage disease. CARACO is a French ongoing trial, built to bring a reply to this important question. A huge effort for inclusion of the patients, and involving new teams, are mandatory.

[Show abstract][Hide abstract] ABSTRACT: To evaluate the patients' satisfaction with breast reconstruction using the autologous latissimus dorsi technique and the impact of the procedure on the quality of life and body image of women who had mastectomy for breast cancer.
A retrospective transversal study was conducted at the Georges François Leclerc Cancer Care Center in Dijon, France. From 1990 to 2008, 193 women underwent reconstruction (RW), among these, 141 were matched for age at diagnosis and the date of the mastectomy with women who did not undergo reconstruction (NRW) identified using data from the Côte d'Or breast cancer registry. Questionnaires concerning quality of life, body image and satisfaction (MBROS-S, MBROS-BI, EORTC QLQ-C30, EORTC QLQ-BR23) were sent through the post following surgery.
The overall response rate was 77% and the mean (MBROS-S) satisfaction score was 3.36. The quality of life (EORTC QLQ-C30, EORTC QLQ-BR23) in RW was no better than that in NRW, but body image was better (p = 0.0247) especially before 60 years (p = 0.0192), in obese patients (p = 0.03) and when the breasts of RW were heavy (p = 0.0197). Moreover, when the time from the mastectomy was less than 4 years, body image (p = 0.0008) and the sexual activity score (p = 0.0078) were higher in RW.
The level of satisfaction was higher in RW, and breast reconstruction made a strong contribution in terms of improvement in body image. A prospective study to evaluate quality of life in the long term is now necessary.

[Show abstract][Hide abstract] ABSTRACT: Central venous catheter placement with an implanted port (portacath) is used to provide long-term venous access. We report a case of metastatic implantation at a port site from a primary cancer of the base of the tongue. Insertion of portacaths must be performed using full sterile precautions to avoid spread of tumor cells; in no case should the port site incisions be in contact with the surgical field in which the tumor resection was performed.

[Show abstract][Hide abstract] ABSTRACT: A modified posterior pelvic exenteration (MPE) might be needed to reach an optimal tumoral reduction. The issue of this study is to relate a multicentric experience of this kind of resection.
Three hundred five patients who needed an MPE were analyzed from 9 French cancer centers. One hundred sixty-eight MPEs were performed during initial surgery (55.1%), 69 during interval surgery (22.6%), 36 after chemotherapy (11.8%), and 32 for recurrences (10.5%).
Three hundred two colorectal anastomoses were realized with a protective stoma in 59 (19.5%) of cases and a stoma closure in 76.5% (51). The rate of functional anastomosis was 96% (290/302). Complications occurred in 26.9% (82/305) of the patients, with a fistula in 25 (8.2%). The reintervention rate was 8.8% (27/305). The median length of hospitalization was 15 days. The absence of a macroscopic residual disease was obtained in 58% (173/303) of cases. A residual disease that was 1 cm or smaller was observed in 73 cases (24%) and 2 cm or smaller observed in 36 (11.9%). Postoperative chemotherapy was started with a median time of 32 days.Postoperative death occurred in 1 patient (0.33%). The survival rates were 62.7% and 27.6% at 2 and 5 years, respectively. With a multivariate analysis, the 2 significant prognostic factors were residual disease and time of surgery (P < 0.0001).
A rectal invasion should not be an obstacle to reach the aim to obtain a macroscopic minimal residual disease or, if possible, the absence of one. An MPE is useful in those cases to reach optimal cytoreduction, with comparable results whatever the patient's age is. A temporary protective stoma should be considered only exceptionally.

[Show abstract][Hide abstract] ABSTRACT: Our purpose was to assess development of sentinel lymph node biopsy (SLNB) in two Burgundy districts during the year 2005.
All women undergoing breast surgery as primary care between 1 January 2005 and 1 January 2006 were eligible for inclusion. Eleven surgeons from five different breast-treatment centres took part in this prospective multicentric study. As our objective was to evaluate practices, patients were not randomized and surgeons were free to choose treatment patterns.
The 528 enrolled cases account for 90% of all new breast cancers in 2005 in Cote d'Or and Saône et Loire. Half of these patients (286) fulfilled requirements for SLNB. The others (242) had primary full axillary clearance (AC). Four of our five centres offer double-detection of sentinel lymph nodes as well as intraoperative pathology examination. Most tumours were invasive ductal carcinomas, with an average size of 12 mm in the SLNB group (T1C) and 22 mm in the AC group (T2). Two or three lymph nodes were removed during each SLNB procedure. Whereas most SLNB studies report around 25% positive nodes, we barely recorded 18.5% (53 of our 256 patients). Moreover, 2/3 of these node-positive patients had optimal care since additional axillary clearance was done right away.
Sentinel lymph node biopsy has become routine practice in our Burgundy area. It is mainly dedicated to early stage breast cancer with limited metastatic risk. Our surgeons follow the most recent guidelines and indications are the same regardless of treatment centre.

[Show abstract][Hide abstract] ABSTRACT: The main aim of this study was to show the interest of pelvic posterior exenteration to obtain complete resection of the tumor in case of invasion of the rectum by contiguity in advanced-stage ovarian cancer. The secondary aim was to determine the morbidity of this surgery.
It is a multicentric, retrospective study of a series of 41 patients, who underwent posterior pelvectomy for advanced-stage ovarian cancer, over a period of 18 years, from July 1989 to July 2007.
The surgery resulted in macroscopically complete resection in 19 patients (46.34%), a residual tumor <2 cm in 19 patients (46.34%) and >2 cm in 3 patients (7.32%). In 34 patients (34/41), digestive continuity with satisfactory anal sphincter function was restored immediately or in the short term. The mean delay to the start of complementary treatment was 36 days. Median overall survival was 33 months.
The main aim of surgery for ovarian peritoneal carcinomatosis is to obtain a complete resection. In the case of direct invasion of the rectum by contiguity, when there is no cleavage plane between the uterus and the rectum, pelvic posterior exenteration is an effective method to achieve this objective. Morbidity is relatively high, but acceptable given the poor prognosis of this disease, the improved survival after surgery, and improvements in post-operative quality of life and functions.

[Show abstract][Hide abstract] ABSTRACT: This prospective multicenter study assessed and compared the impact of different surgical procedures on quality of life (QoL) in breast cancer patients.
The EORTC QLQ-C30 and the EORTC QLQ-BR-23 questionnaires were used to assess global health status (GHS), arm (BRAS) and breast (BRBS) symptom scales, before surgery, just after surgery and 6 and 12 months later. The Kruskal-Wallis test with the Bonferroni correction was used to compare scores. A mixed model analysis of variance for repeated measurements was then applied to assess the longitudinal effect of surgical modalities on QoL.
Before surgery, GHS (P = 0.7807) and BRAS (P = 0.7688) QoL scores were similar whatever the surgical procedure: sentinel node biopsy (SLNB), axillary node dissection (ALND) or SLNB + ALND. As compared with other surgical groups, GHS 75.91 [standard deviation (SD) = 17.44, P = 0.041] and BRAS 11.39 (SD = 15.36, P < 0.0001) were better in the SLNB group 12 months after surgery. Whatever the type of surgery, GHS decreased after surgery (P < 0.0001), but increased 6 months later (P = 0.0016). BRAS symptoms increased just after surgery (P = 0.0329) and until 6 months (P < 0.0001) before decreasing (P < 0.0001).
SLNB improved GHS and BRAS QoL in breast cancer patients. However, surgeons must be cautious, SLNB with ALND results in a poorer QoL.

[Show abstract][Hide abstract] ABSTRACT: Plexiform schwannoma is a form of schwannoma which usually involves cutaneous tissues. It cannot be easily differentiated from malignant tumors, especially deep or cellular lesions. We report a deep plexiform schwannoma which we place among the various benign or malignant nerve sheath tumors, which may or may not develop within the context of genetic disease. Finally, the differential diagnoses are discussed. Recognition of the lesion is necessary for appropriate treatment.

Il s’agit notamment de le différencier de certaines tumeurs malignes, évoquées particulièrement dans le cas de lésions profondes ou cellulaires. Nous rapportons un cas supplémentaire de schwannome plexiforme profond, que nous situons ensuite parmi les variétés de tumeurs bénignes et malignes des gaines nerveuses, qu’elles s’intègrent ou non dans le contexte de maladie génétique. Enfin, nous discutons les principaux diagnostics différentiels de cette tumeur rare dont la reconnaissance parfois délicate doit permettre d’éviter un traitement lourd non adapté.
