RESUMO

PURPOSE: RUBY is a tool for extracting clinical data on breast cancer from French medical records on the basis of named entity recognition models combined with keyword extraction and postprocessing rules. Although initial results showed a high precision of the system in extracting clinical information from surgery, pathology, and biopsy reports (≥92.7%) and good precision in extracting data from consultation reports (81.8%), its validation is needed before its use in routine practice. METHODS: In this work, we analyzed RUBY's performance compared with the manual entry and we evaluated the generalizability of the approach on different sets of reports collected on a span of 40 years. RESULTS: RUBY performed similarly or better than the manual entry for 15 of 27 variables. It showed similar performances when structuring newer reports but failed to extract entities for which changes in terminology appeared. Finally, our tool could automatically structure 15,990 reports in 77 minutes. CONCLUSION: RUBY can automate the data entry process of a set of variables and reduce its burden, but a continuous evaluation of the format and structure of the reports and a subsequent update of the system is necessary to ensure its robustness.

RESUMO

BACKGROUND: To evaluate the feasibility of a same day breast cancer diagnosis and management protocol, consequently decreasing time to treatment and immediately reassuring patients with benign diagnosis. MATERIALS AND METHODS: A total of 60 women underwent breast exam during SENODAY in our cancer center between January 2020 and December 2022. Patients are first seen by a breast surgeon who mentions whether the patient's history and physical exam are suspicious of malignancy. Patients are then sent to the radiologist who performs a complete radiologic assessment, classifies the lesions, and performs a biopsy when necessary. The specimen is sent to the pathologist who uses the imprint cytology technique to obtain a preliminary diagnosis. Effective counseling is established in case of breast cancer diagnosis. RESULTS: Among 60 women, 25 patients were reassured by breast imaging and 35 underwent histopathological analysis (17 patients with a 1-day protocol and 18 with the standard definitive technique). Clinical examination was found to have a sensitivity of 100% and a specificity of 89.47%. The positive predictive value was 80 % and the negative predictive value was 100%. However, we did not find a strong correlation between imaging and definitive pathology. Moreover, on imprint cytology, sensitivity, specificity, PPV, and NPV were 100%. Finally, the mean time-to-treat was 28.6 days. CONCLUSIONS: SENODAY reassured 68.3% of patients. It also offered effective counseling and a treatment plan to newly diagnosed breast cancer patients within 1 day. Same day histological diagnosis by imprint cytology is effective and feasible with an excellent accuracy.

RESUMO

BACKGROUND/AIM: The COVID-19 pandemic introduced drastic containment measures, which had a direct impact on breast cancer management. During the first wave, a delay in care and a decrease in new consultation numbers was observed. It would be interesting to study the resulting long-term consequences on breast cancer presentation and time to first treatment. PATIENTS AND METHODS: This retrospective cohort study was conducted at the surgery Department of the Anti-Cancer Center of Nice, France. Two periods of 6 months were compared: a pandemic period from June to December 2020 (after the end of the first wave), and a control period one year earlier. The primary endpoint was to measure the time to care access. The patients and cancer characteristics and the management type were also compared. RESULTS: A total of 268 patients underwent diagnosis for breast cancer in each period. The time from biopsy to consultation was shortened after the containment was lifted (16 days vs. 18 days, p=0.024). The time between first consultation and treatment was unchanged between the two periods. The tumor size was larger in the pandemic period (21 mm vs. 18 mm, p=0.028). The clinical presentation was different: 59.8% of patients consulted for a palpable mass in the pandemic period, vs. 49.6% in the control period (p=0.023). There was no significant change in therapeutic management. The use of genomic testing was significantly increased. The number of breast cancer cases diagnosed decreased by 30% during the first COVID-19 lockdown. Even though a rebound was expected after the first wave, the number of consultations for breast cancer remained constant. This finding shows the fragility of screening adherence. CONCLUSION: It is necessary to reinforce education in the face of crises that may be repeated. Management of breast cancer did not change, which is a reassuring aspect regarding the care pathway in anticancer centers.

RESUMO

OBJECTIVE: Chemotherapy for high-grade serous ovarian cancers in platinum-sensitive relapse includes carboplatin/paclitaxel, carboplatin/gemcitabine, and carboplatin/pegylated liposomal doxorubicin. According to in vitro data, BRCA mutated patients are sensitive to replicative stress agents but BRCA status is not yet used for the choice of chemotherapy at relapse. Our aim was to assess these doublets according to BRCA status in first platinum-sensitive relapse. METHODS: The ESME ovarian cancer database comprises a multicenter retrospective cohort of patients with ovarian cancer treated in French cancer centers between January 2011 and December 2017. Patients with high-grade serous ovarian cancers at first platinum-sensitive relapse who received one of these doublets were included. The objective was to compare progression-free survival of each chemotherapy doublet according to BRCA status. RESULTS: Among the 10 263 patients in the database, 1539 patients had a first platinum-sensitive relapse: 825 BRCA wild type patients (53.6%) and 304 BRCA mutated patients (19.8%) (7 patients had a homologous recombination mutation and BRCA status was unkown for 403 patients). Median progression-free survival was longer in BRCA mutated patients than in BRCA wild type patients when receiving carboplatin/pegylated liposomal doxorubicin without maintenance treatment (15.8 vs 11.8 months; p<0.001). In contrast, we observed no difference in patients treated with carboplatin/paclitaxel (14.6 vs 14.3 months, respectively; p=0.70) or in those treated with carboplatin/gemcitabine (12.0 vs 9.8 months, respectively; p=0.18). In BRCA wild type patients without maintenance, better progression-free survival occurred with carboplatin/paclitaxel (median progression-free survival 14.3 months) than with carboplatin/gemcitabine and carboplatin/pegylated liposomal doxorubicin (9.8 and 11.8 months, respectively; p=0.017). In BRCA mutated patients without maintenance, there was no difference between the three doublets (median progression-free survival of 14.6, 12.0, and 15.8 months with carboplatin/paclitaxel, carboplatin/gemcitabine, and carboplatin/pegylated liposomal doxorubicin, respectively; p=0.40). CONCLUSION: While treatment with carboplatin/paclitaxel, carboplatin/gemcitabine, and carboplatin/pegylated liposomal doxorubicin shows comparable efficacy in BRCA mutated patients, treatment with carboplatin/paclitaxel appears to be more effective than carboplatin/gemcitabine and carboplatin/pegylated liposomal doxorubicin in BRCA wild type patients with high-grade serous ovarian cancers at first platinum-sensitive relapse.

RESUMO

Background and Purpose: Breast intra operative radiation therapy has been evaluated with different systems delivering 20-21 Gy with treatment times around 30 min. Papillon + TM Contact X-ray machine was designed to produce a 50 kVp beam with a high dose rate ≥ 15 Gy/minute. A pilot study with the first prototype was conducted in Nice. Materials and methods: The inclusion criteria were age ≥ 60 years, unifocal ductal breast adenocarcinoma ≤ 2.5 cm, grade 1-2. Surgical local excision with sentinel node dissection was performed and the applicator was placed in the tumor bed after excision with a prescribed dose of 20 Gy. The main end point of the study was the doses measured with the Gafchromic films; two were located at the skin surface and two in the excision cavity. Secondary endpoints were early toxicity and relapse free survival. Results: Between 10/2018 and 09/2019, 26 patients were included. Mean Gafchromic doses were 18.8 Gy ± 2 Gy at the south pole, 15.6 Gy ± 2.81 Gy at the equator and 2.5 Gy ± 1.67 Gy at the skin. With a median follow-up time of 12 months, no skin or subcutaneous toxicity > grade 2, no local relapse and no metastasis were observed. Conclusion: This is the first phase II study testing the Papillon + tm system for breast IORT with in vivo dosimetry measurements and reassuring clinical data.

RESUMO

BACKGROUND: In spite of the frequency and clinical impact of BRCA1/2 alterations in high-grade epithelial ovarian cancer (HGEOC), real-world information based on robust data warehouse has been scarce to date. METHODS: Consecutive patients with BRCA-mutated HGEOC treated between 2011 and 2016 within French comprehensive cancer centers from the Unicancer network were extracted from the ESME database. The main objective of the study was the assessment of clinicopathological and treatments parameters. RESULTS: Out of the 8021 patients included in the ESME database, 266 patients matching the selection criteria were included. BRCA1 mutation was found in 191 (71.8%) patients, while 75 (28.2%) had a BRCA2 mutation only; 95.5% of patients received a cytoreductive surgery. All patients received a taxane/platinum-based chemotherapy (median = six cycles). Complete and partial response were obtained in 53.3% and 20.4% of the cases, respectively. Maintenance therapy was administered in 55.3% of the cases, bevacizumab being the most common agent. After a median follow up of 51.7 months, a median progression-free survival of 28.6 months (95% confidence interval (CI) [26.5; 32.7]) and an estimated 5-year median overall survival of 69.2% (95% CI [61.6; 70.3]) were reported. Notably, BRCA1- and BRCA2-mutated cases exhibited a trend towards different median progression-free survivals, with 28.0 (95% CI [24.4; 32.3]) and 33.3 months (95% CI [26.7; 46.1]), respectively (p-value = 0.053). Furthermore, five-year OS for BRCA1-mutated patients was 64.5% (95% CI [59.7; 69.2]), while it was 82.5% (95% CI [76.6; 88.5]) for BRCA2-mutated ones (p-value = 0.029). CONCLUSIONS: This study reports the largest French multicenter cohort of BRCA-mutated HGEOCs based on robust data from the ESME, exhibiting relevant real-world data regarding this specific population.

RESUMO

PURPOSE: Electronic medical records are a valuable source of information about patients' clinical status but are often free-text documents that require laborious manual review to be exploited. Techniques from computer science have been investigated, but the literature has marginally focused on non-English language texts. We developed RUBY, a tool designed in collaboration with IBM-France to automatically structure clinical information from French medical records of patients with breast cancer. MATERIALS AND METHODS: RUBY, which exploits state-of-the-art Named Entity Recognition models combined with keyword extraction and postprocessing rules, was applied on clinical texts. We investigated the precision of RUBY in extracting the target information. RESULTS: RUBY has an average precision of 92.8% for the Surgery report, 92.7% for the Pathology report, 98.1% for the Biopsy report, and 81.8% for the Consultation report. CONCLUSION: These results show that the automatic approach has the potential to effectively extract clinical knowledge from an extensive set of electronic medical records, reducing the manual effort required and saving a significant amount of time. A deeper semantic analysis and further understanding of the context in the text, as well as training on a larger and more recent set of reports, including those containing highly variable entities and the use of ontologies, could further improve the results.

RESUMO

OBJECTIVE: Interval debulking surgery is recommended after 3-4 cycles (standard IDS) of neoadjuvant chemotherapy (NACT) for epithelial ovarian cancer (EOC) not able to received upfront complete debulking surgery. However, real world practices frequently report performing IDS after ≥5 NAC cycles (delayed IDS). The aim of this work was to evaluate the impact on survival of the number of NACT cycles before IDS. METHODS: We identified from a French national database, women with newly diagnosed EOC who underwent IDS from January 2011 to December 2016. Progression free survival (PFS) and overall survival (OS) were compared using Cox model with adjustments for confounding factors provided by two propensity score methods: inverse probability of treatment weighting (IPTW) and matched-pair analysis. RESULTS: 928 patients treated by IDS for which our propensity score could be applied were identified. After a median follow-up of 49.0 months (95% CI [46.0;52.9]); from the IPTW analysis, median PFS was 17.6 months and 11.5 months (HR = 1.42; CI 95% [1.22-1.67]; p < 0.0001); median OS was 51.2 months and 44.3 months (HR = 1.29; CI 95% [1.06-1.56]; p = 0.0095) for the standard and delayed IDS groups. From the matched-pair analysis (comparing 352 patients for each group), standard IDS was associated with better PFS (HR = 0,77; CI 95% [0.65-0.90]; p = 0.018) but not significantly associated with better OS (HR = 0,84; CI 95% [0.68-1,03]; p = 0.0947). CONCLUSIONS: Carrying IDS after ≥5 NACT cycles seems to have a negative effect on patients survival. The goal of IDS surgery is complete resection and should not be performed after >3-4 NACT cycles.

RESUMO

PURPOSE: The French National Cancer Institute has developed, in partnership with the French National Authority for Health, breast cancer-specific Care Quality, and Safety Indicators (BC QIs). With regard to the most common form of cancer, our aim is to support local and national quality initiatives, to improve BC pathways and outcomes, reduce heterogeneity of practice and regional inequities. In this study, we measure the BC QIs available in the French National medico-administrative cancer database, the French Cancer Cohort, for 2018. MATERIALS AND METHODS: BC QIs are developed according to the RAND method. QIs are based on good clinical practice and care pathway recommendations. QI computation should be automatable without any additional workload for data collection. They will be published annually for all stakeholders, and especially hospitals. RESULTS: Finally, ten feasible and pertinent QIs were selected. In France, BC care was found to be close to compliance with most QIs: proportion of patients undergoing biopsy prior to first treatment (94.5%), proportion of patients undergoing adjuvant radiotherapy after breast-conserving surgery for BC (94.5%), proportion of women undergoing radiotherapy within 12 weeks after surgery and without chemotherapy (86.2%), proportion of DCIS patients undergoing immediate breast reconstruction (54.3%) and proportion of women with NMIBC undergoing breast reintervention (14.4%). However, some are still far from their recommended rate. In particular, some QIs vary considerably from one region, or one patient, to another. CONCLUSION: Each result needs to be analyzed locally to find care quality leverage. This will strengthen transparency actions aimed at the public.

RESUMO

OBJECTIVE: To determine the value of performing a risk-reducting mastectomy (RRM) in the absence of a deleterious variant of a breast cancer susceptibility gene, in 4 clinical situations at risk of breast cancer. DESIGN: The CNGOF Commission of Senology, composed of 26 experts, developed these recommendations. A policy of declaration and monitoring of links of interest was applied throughout the process of making the recommendations. Similarly, the development of these recommendations did not benefit from any funding from a company marketing a health product. The Commission of Senology adhered to the AGREE II (Advancing guideline development, reporting and evaluation in healthcare) criteria and followed the Grading of Recommendations Assessment, Development and Evaluation (GRADE) method to assess the quality of the evidence on which the recommendations were based. The potential drawbacks of making recommendations in the presence of poor quality or insufficient evidence were highlighted. METHODS: The Commission of Senology considered 8 questions on 4 topics, focusing on histological, familial (no identified genetic abnormality), radiological (of unrecognized cancer), and radiation (history of Hodgkin's disease) risk. For each situation, it was determined whether performing RRM compared with surveillance would decrease the risk of developing breast cancer and/or increase survival. RESULTS: The Commission of Senology synthesis and application of the GRADE method resulted in 11 recommendations, 6 with a high level of evidence (GRADE 1±) and 5 with a low level of evidence (GRADE 2±). CONCLUSION: There was significant agreement among the Commission of Senology members on recommendations to improve practice for performing or not performing RRM in the clinical setting.

RESUMO

BACKGROUND: Prognostic significance of endometrioid epithelial ovarian cancer (EOC) is controversial. We compared clinical, pathological, and biological features of patients with endometrioid and serous EOC, and assessed the independent effect of histology on outcomes. METHODS: We conducted a multicenter retrospective analysis of patients with EOC selected from the French Epidemiological Strategy and Medical Economics OC database between 2011 and 2016. Our main objective was to compare overall survival (OS) in endometrioid and serous tumors of all grades. Our second objectives were progression-free survival (PFS) and prognostic features. RESULTS: Out of 10,263 patients included, 3180 cases with a confirmed diagnosis of serous (N = 2854) or endometrioid (N = 326) EOC were selected. Patients with endometrioid histology were younger, more often diagnosed at an early stage, with lower-grade tumors, more frequently dMMR/MSI-high, and presented more personal/familial histories of Lynch syndrome-associated cancers. BRCA1/2 mutations were more frequently identified in the serous population. Endometrioid patients were less likely to receive chemotherapy, with less bevacizumab. After median follow-up of 51.7 months (95CI[50.1-53.6]), five-year OS rate was 81% (95CI[74-85]) in the endometrioid subgroup vs. 55% (95CI[53-57] in the serous subset (p < 0.001, log-rank test). In multivariate analyses including [age, ECOG-PS, FIGO, grade, and histology], the endometrioid subtype was independently associated with better OS (HR = 0.38, 95CI[0.20-0.70], p= 0.002) and PFS (HR = 0.53, 95CI[0.37-0.75], p < 0.001). CONCLUSIONS: Clinicopathological features at diagnosis are not the same for endometrioid and serous EOC. Endometrioid histology is an independent prognosis factor in EOC. These observations suggest the endometrioid population requires dedicated clinical trials and management.

RESUMO

INTRODUCTION: Invasive breast cancer without clinical adenopathy (cN0) is currently explored by the sentinel node (GS) technique, except in the case of positive preoperative radio-cytological screening, where axillary curage (CA) remains systematic from the outset. Since the publication of the ACOSOG-Z0011 trial, abstention from CA is possible in patients presenting less than three metastatic GS. As a result, the value of axillary radio-cytological screening is being questioned as it could potentially lead to axillary surgical over-treatment. The objective of this study was to study clinically N0 patients with positive axillary cytology and to compare it to a group of patients with positive GS. METHOD: One hundred and forty-seven patients with cN0 pN+ breast cancer treated between 2014 and 2016 were selected retrospectively. Two groups were constituted according to the initial radio-cytological evaluation. A CA was systematically performed. RESULTS: Thirty-one patients with positive axillary cytology (n=31 vs. n=116) had more metastatic lymph nodes (P=0.01) in the AC, larger (P<0.001), less differentiated (P<0.001) tumours, and shorter recurrence-free survival (P=0.0114). It also appeared that 38.7 % of patients with a positive cytology had at most two metastatic nodes and could, according to the results of ACOSOG, benefit from therapeutic de-escalation. CONCLUSION: X-ray cytological screening remains essential in order to select a subgroup of patients with a high lymph node tumour load. Additional studies are necessary in order to be able to offer therapeutic de-escalation to 1/3 of these patients without the risk of under-treatment for the remaining 2/3.

RESUMO

INTRODUCTION: During the COVID-19 pandemic, the containment measures and the recommendations of several societies in oncology may have impacted the request for initial care for cancers. METHODS: In this monocentric retrospective study, the number and the characteristics of patients received for a first consultation for a breast or gynecologic tumor were compared between the containment period and a control period. The times from diagnosis to treatment and the type of initial care were compared too. RESULTS: During the outbreak, 91 patients were seen for a new request, versus 159 during the control period, a decrease of 43.5 %. Patients were older (62.9 versus 60.9 years old) but this difference was not significant. Tumor stage was not modified. Concerning senology, the time from the biopsy to the first consultation was 5.5 days longer during the outbreak (difference statistically insignificant). Among the 51 patients requiring a surgical treatment during the outbreak, 16 (31.48 %) were postponed after the end of the containment measures. After all, the average time from the consultation to the treatment was not modified. No modification of type of treatment was observed. DISCUSSION: At the height of the pandemic, benefits and risks of the cancer treatment had to be daily balanced against the risk of exposition to the COVID-19. The evaluation of practices for cancer care is essential to understand the real impact of COVID-19 outbreak on global cancer management, so as to get prepared to further crises.

RESUMO

PURPOSE: Iodine-125 (125I) seeds can be used as landmarks to locate non-palpable breast lesions instead of implanting metal wires. This relatively new technique requires a nuclear probe usually used for technetium-99m (99mTc) sentinel node detection. This study aimed to compare the performances of different probes and valid the feasibility of this technique, especially in the case of simultaneous 125I-seed and 99mTc breast cancer surgery. METHODS: Three probes with different features (SOE-3211, SOE-3214 and GammaSUP-II) were characterised according to the NEMA NU3-2004 standards for a 99mTc source and a 125I-seed. Several tests such as sensitivity, linearity or spatial resolution allowed an objective comparison of their performances. NEMA testing was extended to work on signals discrimination in case of simultaneous detection of two different sources (innovative figure of merit "Shift Index") and to assess the 99mTc scatter fraction, a useful parameter for the improvement of the probes in terms of detector materials and electronic system. RESULTS: Although the GammaSUP-II probe saturated at a lower activity (1.6 MBq at 10 mm depth), it allowed better sensitivity and spatial resolution at the different NEMA tests performed with the 99mTc source (7865 cps/MBq and 15 mm FWHM at 10 mm depth). With the 125I-seed, the GammaSUP-II was the most sensitive probe (3106 cps/MBq at 10 mm depth) and the SOE-3211 probe had the best spatial resolution (FWHM 20 mm at 10 mm depth). The SOE-3214 probe was more efficient on discriminating 125I from 99mTc in case of simultaneous detection. The SOE probes were more efficient concerning 99mTc scatter fraction assessments. The SOE-3211 probe, with overall polyvalent performances, seemed to be an interesting trade-off for detection of both 125I and 99mTc. CONCLUSION: The three probes showed heterogeneous performances but were all suitable for simultaneous 99mTc sentinel node and 125I-seed detection. This study provides an objective and innovative methodology to compare probes performances and then choose the best trade-off regarding their expected use.

RESUMO

BACKGROUND: Dihydropyrimidine dehydrogenase (DPD) status is an indicator of a marked risk for toxicity following fluoropyrimidine (FP)-based chemotherapy. This notion is well-established for low DPD status but little is known about the clinical impact of high DPD activity. This study examined the possible link between high intrinsic lymphocytic DPD activity and overall survival, progression free survival and response to FP-based treatment in patients treated in our institution. METHODS: Lymphocytic DPD activity was assessed in a group of 136 patients receiving FP-based chemotherapy from 2004 to 2016. There were 105 digestive (77.2%), 24 breast (17.6%) and 7 head and neck cancers (5.2%). Cox or logistic regression models were applied with adjustment on all confounding factors that could modify OS, PFS or response. All models were stratified on the three cancer locations. A cut-off for DPD activity was assessed graphically and analytically. RESULTS: An optimal cut-off for DPD activity at 0.30 nmol/min/mg protein was identified as the best value for discriminating survivals and response. In multivariate analysis, individual lymphocytic DPD activity was significantly related to overall survival (p = 0.013; HR: 3.35 CI95%[1.27-8.86]), progression-free survival (p < 0.001; HR: 3.15 CI95%[1.75-5.66]) and response rate (p = 0.033; HR: 0.33 CI95%[0.12-0.92]) with a marked detrimental effect associated with high DPD activity. CONCLUSIONS: DPD status screening should result in a two-pronged approach with FP dose reduction in case of low intrinsic DPD and, inversely, an increased FP dose for high intrinsic DPD. In a context of personalized FP-based treatment, this innovative strategy needs to be prospectively validated.

RESUMO

OBJECTIVES: To evaluate the impact of systematic radiological review by breast specialist radiologist of malignant breast lesion imaging on the therapeutic management of patients. MATERIALS AND METHODS: Data collection was performed for patients with histopathologically proved breast cancer or suspicious breast lesion on imaging realized out of our institution. Patients underwent systematic mammary and axillary ultrasound, imaging review and if necessary complementary mammographic images. We analyzed the number of additional breast biopsies and axillary lymph node fine needle aspiration (FNA) with their histopathological results. We assessed their impact by comparing the final surgical treatment to the one planned before review. RESULTS: Two hundred and seventeen patients were included, with a total of 230 BIRADS 0, 4, 5 or 6 breast lesions. Seventy-six additional breast core biopsies were realized, leading to diagnose 43 additional BIRADS 6 lesions (24 infiltrative carcinomas, 9 DCIS and 10 atypical lesions) in 30 patients (13.82%). Thirty-five additional lymph node FNA were realized with 12 metastatic nodes and 3 false negative samples. Imaging review lead to change surgical treatment in 59 patients (27.19%, P<0.01) with modification in breast surgery in 37 patients, axillary surgery in 8 patients and both sites surgery in 12 patients. CONCLUSION: This study shows an impact of systematic radiological review by breast specialist radiologist in therapeutic management of patients treated for malignant breast lesion.

RESUMO

PURPOSE: To evaluate the feasibility and toxicity of a single-fraction 8-Gy stereotactic boost after whole-breast irradiation in early breast cancer. The primary aim of this phase 2 study was to evaluate cutaneous breast toxicity using National Cancer Institute Common Terminology Criteria for Adverse Events (version 4) 3 months after the boost. Secondary objectives were local control, survival, and patient-reported quality of life using the European Organisation for Research and Treatment of Cancer QLQ-C30 and breast-specific European Organisation for Research and Treatment of Cancer QLQ-BR 23 questionnaires. METHODS AND MATERIALS: Patients with invasive ductal or lobular pT1-2 breast cancer treated with lumpectomy with clear margins and pN0 were included. Patients requiring chemotherapy were excluded. RESULTS: Twenty-eight eligible patients received the planned boost, and 26 had hormonal therapy. The procedure was technically successful without procedural complications. A median of 3 fiducials were tracked, and 115 beams were used. There were 22 acute grade 1 breast skin toxicities, including fibrosis, pain, erythema, or pigmentation. There were 2 acute grade 2 erythemas. Median skin boost dose was inversely correlated with acute skin toxicity (P = .028). QLQ-C30 scores revealed acute dyspnea and arm symptoms without correlation to the boost dose. Breast symptom QLQ-BR23 scores did not deteriorate, although upset with hair loss and systemic side effects of hormonal therapy were observed. After a median follow-up of 38 months, 1 patient had in-boost-field relapse, and there were 5 late grade 1 and 1 grade 2 skin toxicities. CONCLUSIONS: Single-fraction stereotactic boost after conventional whole-breast irradiation in early breast cancer is feasible with minor toxicities. Quality of life and specific breast items showed excellent patient acceptance.

RESUMO

BACKGROUND: Sentinel node and occult lesion localization (SNOLL) calls for a combination of two specific procedures: intraoperative detection of sentinel lymph node (SLN) and radio-guided occult lesion localization (ROLL). The safety and benefits of radio-guided localization in the surgical treatment of non-palpable breast cancer have been confirmed. The aim of this study was to evaluate the potential role for an intra-operative handheld tumor resection gamma camera (TReCam) in SNOLL procedures. METHODS: Fifteen patients were enrolled. The SNOLL procedure was performed in all patients with conventional lymphoscintigraphy (LS). TReCam was used to obtain nuclear imaging in the operating theater. Concordance between LS and TReCam images, duration of use and assessment of difficulties in data acquisition with TReCam were reported. RESULTS: Concordance for tumor localization between single-detector gamma probe and TReCam was excellent (15/15). The number of radioactive SLNs visualized between LS and TReCam was equivalent in 53.3% of cases (8/15). TReCam was considered to be very easy-to-use (12/15) or easy-to-use (3/15). Average duration of acquisition with TReCam was 4 minutes and 45 seconds for the SLN procedure, and 2 minutes and 10 seconds for lumpectomy. CONCLUSIONS: This study suggests that TReCam is easy-to-use and does not increase operative time. Its exact role in radio-guided surgery needs to be clearly defined in a larger study. However, its usefulness and benefits in radio-guided breast surgery seem to be promising.
