RFID trial: localization of non-palpable breast lesions using radiofrequency identification tags or wire.

BACKGROUND: Breast cancer is the most frequently diagnosed cancer and the leading cause of cancer death in women. Approximately 50% of breast cancers are discovered at an early stage in patients for whom conservative surgery is indicated. Intraoperative localization of non-palpable breast lesions is generally accomplished using a hook wire to mark the area of concern under ultrasound or stereotactic localization. But this technique has several drawbacks (painful, stressful…). We propose the use of a wire-free breast lesion system using miniature radiofrequency identification (RFID) tags. This technique could improve patient comfort and surgical comfort for surgeons. We therefore propose a study to assess the interest of introducing the RFID localization technique at the Jean PERRIN comprehensive cancer center. METHODS: This is a single-center prospective trial designed to assess the interest in introducing the RFID localization technique at the Jean Perrin center. It aims to show the superiority of the RFID technique in terms of patient tolerance compared to the gold-standard (hook wire). A sequential inclusion in time will be performed: 20 inclusions in the gold-standard group, then 20 patients in the RFID group before repeating the inclusion scheme. Any patient requiring preoperative localization will receive a senology consultation. The RFID tag will be placed during this consultation. The hook wire localization will be done the day before the surgery. Patients will fill out a Hospital Anxiety and Depression scale (HAD) questionnaire at the time of inclusion. They will then fill out a satisfaction questionnaire in 2 steps: during the placement of the device (RFID tag or hook wire) or during the postoperative consultation at 1 month. Radiologists and surgeons will fill out a questionnaire to evaluate the localization technique, respectively after the localization and surgery procedures. DISCUSSION: The RFID study is the first study in France which specifically assesses the interest of the RFID localization in terms of patients comfort. Patient comfort is one of the key elements to take into consideration when managing patients in oncology and new technologies such as RFID tags could improve it.

Quality of life for older patients with cancer: a review of the evidence supporting melatonin use.

PURPOSE: The proportion of older populations living with cancer is on the increase. Maintaining or improving their quality of life (QoL) has become an important goal in the treatment of cancer and has become an endpoint in clinical trials. Melatonin regulates a wide variety of physiological functions and is involved in the initiation of sleep and the improvement of QoL. With age, the secretion of melatonin decreases and could lead to a deterioration in QoL. METHODS: Literature searches were conducted using the PubMed database. The search terms and derivatives of "metastatic cancer", "older patients", "quality of life" and "melatonin" were used. Titles and abstracts were screened to identify whether studies were relevant for full-text screening. RESULTS: There is major concern about the symptoms older cancer patients encounter during treatment because they can impact their QoL. Melatonin supplementation presents several benefits for older patients: improvement in survival, decrease in symptoms induced by cancer and cancer treatment, and also improvements in quality of life. CONCLUSION: It therefore seems appropriate to study the impact of melatonin supplementation during cytotoxic therapy on QoL among elderly patients with metastatic cancer. The use of melatonin as a therapeutic strategy seems particularly suitable for elderly patients, a population known to secrete significantly less melatonin. However, to date, no studies have been conducted in this population.

Treatment-Induced Cardiotoxicity in Breast Cancer: A Review of the Interest of Practicing a Physical Activity.

Physical activity is known to prevent the occurrence of cancer and decrease the risk of breast cancer. At diagnosis of breast cancer, fewer than half of the patients reach the international recommendation for physical activity. However, breast cancer patients, and particularly HER2+ breast cancer patients, are exposed to treatment-induced cardiotoxicity because of a side effect of 2 molecules used in standard therapy to treat these tumors, i.e., anthracycline and trastuzumab. Cardiotoxicity can sometimes lead to discontinuation of the treatment and even to the development of cardiovascular diseases. Exercise is known to protect the cardiovascular system in the healthy population. Consequently, being physically active during treatment appears to be a way to prevent the negative impact of cancer treatment on the heart in this population. In particular, aerobic exercising could have a protective effect against treatment-induced cardiotoxicity. A supervised physical activity program seems to be the best way for breast cancer patients to be active during treatment. However, there is very little information, and in particular a lack of guidelines, on exercising available to patients. The interventional trials that have been conducted on this topic are very heterogeneous and no standard recommendations have been made available for cancer patients thus far. An effective physical activity program needs to take each patient's barriers and motivations into account in order to encourage the practice of physical activity throughout treatment. To ensure the success of the program, it is essential to facilitate adherence and especially maintain motivation. Further studies are needed to determine what practice guidelines oncologists should give their patients.

A Retrospective Study on the Onset of Menopause after Chemotherapy: Analysis of Data Extracted from the Jean Perrin Comprehensive Cancer Center Database Concerning 345 Young Breast Cancer Patients Diagnosed between 1994 and 2012.

OBJECTIVE: Young breast cancer (BC) patients receiving chemotherapy are at risk of chemotherapy-induced menopause (CIM). We sought to define the incidence rate of premature menopause after chemotherapy and to retrospectively investigate factors related to the onset of menopause. METHODS: We identified BC patients who had received chemotherapy at the Cancer Center (Centre Jean-Perrin). We selected premenopausal women aged between 18 and 50 years at the moment of diagnosis who received chemotherapy between 1994 and 2012. RESULTS: Of the 345 selected patients, the median age was 42 years (interquartile range: 38-46). CIM was defined as amenorrhea for at least 2 years following the end of chemotherapy. A total of 260 premenopausal women versus 85 menopausal women were included. Among the 85 menopausal women, only 46 were in the CIM group (13.3%). This rate increased in the group of women aged >43 years at diagnosis and with early hot flushes. CONCLUSION: CIM occurred in 13.3% of BC patients after chemotherapy. Age >43 years and early hot flushes were significantly associated with the risk of CIM. We suggest that the definition of CIM should be standardized in the literature: "amenorrhea of at least 2 years" seems a good cutoff, although 2 patients recovered their menstrual cycles beyond this limit.

The New Combination Docetaxel, Prednisone and Curcumin in Patients with Castration-Resistant Prostate Cancer: A Pilot Phase II Study.

OBJECTIVES: Favorable phase I results justified this pilot phase II study to assess the efficacy of docetaxel/curcumin in patients with chemotherapy-naive metastatic castration-resistant prostate cancer (CRPC). METHODS: Thirty patients with progressing CRPC and a rising prostate-specific antigen (PSA) received docetaxel/prednisone in standard conditions for 6 cycles in combination with per os curcumin, 6,000 mg/day (day -4 to day +2 of docetaxel). The co-primary endpoint was the overall response rate determined by PSA and target assessments. An ancillary study assessed the seric values of chromogranin A (CgA) and neuron-specific enolase (NSE). RESULTS: Twenty-six patients received the scheduled treatment, 2 progressed and 2 died before the end of treatment. A PSA response was observed in 59% of patients (14% of PSA normalization) and achieved within the first three cycles for 88% of responders. Partial response was reached for 40% of evaluable patients. The regimen was well tolerated, and no adverse event was attributed to curcumin. Twenty patients were 100% curcumin compliant. The PSA level and objective response rate were not correlated with the serum values of CgA and NSE. CONCLUSION: This study produced additional data on curcumin as a treatment for cancer, with a high response rate, good tolerability and patient acceptability, justifying the interest to conduct a randomized trial.

Is it important to adapt neoadjuvant chemotherapy to the visible clinical response? An open randomized phase II study comparing response-guided and standard treatments in HER2-negative operable breast cancer.

BACKGROUND: Neoadjuvant treatment provides a unique opportunity to evaluate individual tumor sensitivity. This study evaluated whether a response-guided strategy could improve clinical outcome compared with a standard treatment. METHODS: Overall, 264 previously untreated stage II-III operable breast cancer patients were randomized to receive either standard treatment (arm A, n = 131), consisting of fluorouracil, epirubicin, and cyclophosphamide (FEC100: 500, 100, and 500 mg/m(2), respectively, for 3 cycles) followed by docetaxel (100 mg/m(2) for 3 cycles), or adapted treatment (arm B, n = 133), beginning with 2 cycles of FEC100 and switching to docetaxel if tumor size decreased by <30% after 2 cycles or <50% after 4 cycles of FEC100 (ultrasound assessments according to World Health Organization criteria). Otherwise, FEC100 was given for six cycles before surgery. Intent-to-treat analysis was performed. RESULTS: Similar results were observed for clinical response (objective response was 54% vs 56%, p = .18), breast conservation surgery (BCS; 67% vs 68%, p = .97), and pathological complete response rate (Chevallier classification: 14% vs 11%, p = .68; Statloff classification: 16% vs 13%, p = .82) between arms A and B. Similar toxicities were observed, even with unbalanced numbers of FEC100 and docetaxel courses. CONCLUSION: Adapted and standard treatments had similar results in terms of tumor response, BCS rate, and tolerability. Further survival outcome data are expected.

Prognostic factors in operable breast cancer treated with neoadjuvant chemotherapy: towards a quantification of residual disease.

OBJECTIVE: Neoadjuvant chemotherapy (NACT) allows for a more frequent use of breast-conservative surgery; it is also an in vivo model of individual tumor sensitivity which permits to determine new prognostic factors to personalize the therapeutic approach. METHODS: Between 2000 and 2012, 318 patients with primary invasive breast cancer were treated with a median of 6 cycles of NACT; they received either an anthracycline-based FEC 100 protocol (31.1%), or anthracyclines + taxanes (53.5%), with trastuzumab if indicated (15.4%). RESULTS: After a median follow-up of 44.2 months, the pathological complete response rate according to the classification of Chevallier et al. [Am J Clin Oncol 1993;16:223-228] was 19.3%, and overall (OS) and disease-free survival (DFS) at 10 years were 60.2 and 69.6%, respectively. Univariate analyses demonstrated that the Residual Disease in Breast and Nodes (RDBN) index was the most significant prognostic factor for OS (p = 0.0082) and DFS (p = 0.0022), and multivariate analyses mainly revealed that the residual tumor size, residual involved node number and post-chemotherapy Scarff-Bloom-Richardson (SBR) grading were the most significant prognostic factors. CONCLUSIONS: In a cohort of patients who were all homogeneously treated with some of the most common drugs for breast cancer, we demonstrate that NACT may provide additional prognostic factors and confirm the RDBN index. As this index allows for the prediction of survival with different breast cancer subtypes, we suggest that it should be calculated routinely to help clinicians to select patients who need adjuvant treatments.

Neurotoxicity as a prognostic factor in patients with metastatic breast cancer treated with ixabepilone as a first-line therapy.

OBJECTIVE: This study is a longitudinal follow-up of metastatic breast cancer patients treated with ixabepilone as first-line chemotherapy, with the aim to evaluate the association between a mechanism-based neurotoxicity and the efficacy of ixabepilone. PATIENTS AND METHODS: At the 2 main investigational sites of a phase II clinical trial, 50 patients previously treated with anthracycline received ixabepilone. A chart review was performed to evaluate overall survival (OS) and time to progression (TTP) and to describe the subsequent treatments. RESULTS: The severe neurotoxicity induced by ixabepilone (38%) is correlated with a higher overall response rate to ixabepilone (79 vs. 48%; p = 0.042), a longer TTP (11.4 vs. 6.8 months; p = 0.023) and a longer OS (36.6 vs. 19.9 months; p = 0.05). After ixabepilone discontinuation, patients received a median of 4 subsequent chemotherapy lines (range 1-12). Among the 31 patients who received taxanes, neither the neurotoxicity incidence under treatment with taxanes nor the response was affected by a previous occurrence under ixabepilone treatment. CONCLUSION: These findings suggest that neurotoxicity development under ixabepilone treatment is a predictor of treatment outcomes as well as a favorable prognostic factor. It highlights the risk-to-benefit ratio issue of ixabepilone. We noticed the possibility to treat patients with taxanes after ixabepilone without systematic recurrent neurotoxicity.

Everolimus in Metastatic Breast Cancer: Clinical Experience as a Late Treatment Line.

BACKGROUND: Everolimus (Afinitor®) plus exemestane are indicated for hormone receptor-positive, HER2/neu-negative metastatic breast cancer (MBC), in menopausal women without symptomatic visceral disease after recurrence or progression following aromatase inhibitors. But everolimus efficacy as late treatment has not been explored. METHODS: Sixty-three MBC patients progressing under hormonotherapy (HT; n = 30) or after chemotherapy (CT; n = 32) received everolimus plus HT (EHT) and were analyzed for safety, efficacy and overall survival (OS). This cohort was compared with our previous 530 MBC patients stratified by line (PMID 21852136). RESULTS: The median duration of EHT was 27.8 weeks at 5-10 mg/day until clinical progression or toxicity. Median OS was not reached (median follow-up 18 months). Twelve-month survival was 100, 79 and 49% for patients treated with 0 (n = 13), 1-2 (n = 18) and >3 CT (n = 32), respectively. Median time-to-treatment failure was 6.4 months. In 62 EHT patients randomly matched 1:7 with 421 previous patients for age and number of CT, OS improved compared with patients receiving a new CT (p = 0.062). In patients pretreated with <2 CT, EHT gave a better OS than in those with a new CT (p = 0.026). CONCLUSIONS: These results may support the use of EHT whatever the number of previous lines.

Comparison of the Predictive and Prognostic Capacities of Neutrophil, Lymphocyte and Platelet Counts and Tumor-infiltrating Lymphocytes in Triple-negative Breast Cancer: Preliminary Results of the PERCEPTION Study.

BACKGROUND/AIM: Triple-negative breast cancer (TNBC) is the most heterogeneous breast cancer subtype, posing numerous challenges in clinical decision-making. Biomarkers are essential to personalize management of TNBC patients. While tumor infiltrating lymphocytes (TILs) are validated prognostic biomarkers, the requirement for tumor biopsy limits their routine use. Therefore, more accessible and reliable quantitative biomarkers are needed. Given the significant role of systemic inflammatory response in tumor onset and progression, assessing inflammatory cells via liquid biopsies emerges as a promising alternative. PATIENTS AND METHODS: The PERCEPTION study, conducted at Centre Jean Perrin in France, aims to determine the correlation between TILs and peripheral blood components at diagnosis. An interim analysis was conducted after enrolling 50% of the estimated population, to evaluate study feasibility and preliminary correlations between blood cell counts and TILs. RESULTS: Sixty-one patients were enrolled over 4.5 years, demonstrating a good inclusion rate with minimal missing data. Preliminary results for 36 analyzable patients showed no correlation between the neutrophil-to-lymphocyte ratio (NLR) and TILs (rs=-0.19, 95%CI=-0.49-0.16, p=0.3). However, a moderate, positive, statistically significant correlation was found between NLR and the CD8/FoxP3 TILs ratio (rs=0.36, 95%CI=0.03-0.64, p=0.043). The probabilistic index of 0.7 (p=0.06) between NLR-high and NLR-low groups for this ratio supports the correlation. CONCLUSION: The interim analysis of the PERCEPTION study confirms the feasibility of correlating blood cell counts with TILs in TNBC. Although no significant correlation was observed between NLR and TILs, the moderate positive correlation between the CD8/FoxP3 ratio and TILs suggests a potential link between systemic inflammation and local immune response. These findings underscore the potential of blood-based markers as non-invasive surrogates for TILs, encouraging further research to enhance prognosis and guide treatment strategies in TNBC.

INSTIGO Trial: Evaluation of a Plasma Protein Profile as a Predictive Biomarker for Metastatic Relapse of Triple Negative Breast Cancer.

BACKGROUND: Triple negative breast cancer (TNBC) accounts for 10-20% of breast cancers but has no specific therapy. While TNBC may be more sensitive to chemotherapy than other types of breast cancer, it has a poor prognosis. Most TNBC relapses occur during the five years following treatment, however predictive biomarkers of metastatic relapse are still lacking. High tumour-infiltrating lymphocytes (TILs) levels before and after neo-adjuvant chemotherapy (NAC) are associated with lower relapse risk and longer survival but TILs assessment is highly error-prone and still not introduced into the clinic. Therefore, having reliable biomarker of relapse, but easier to assess, remains essential for TNBC management. Searching for such biomarkers among serum/plasma proteins, circulating tumoral DNA (ctDNA) and blood cells appear relevant. METHODS: This single-centre and prospective study aims to discover predictive biomarkers of TNBC relapse and particularly focuses on plasma proteins. Blood samples will be taken at diagnosis, on the day of first-line or post-NAC surgery, on the day of radiotherapy start, then 6 months and one year after radiotherapy. A blood sample will be taken at the time of metastatic relapse diagnosis. Blood samples will be used for circulating protein quantification, blood cell counts and circulating tumour DNA quantification. A tumour RNA signature, based on the analysis of the RNA expression of 6 genes, will also be tested from the initial biopsy taken routinely. In NAC patients, TILs quantity will be assessed on TNBC pre-treatment biopsy and surgical specimen. ETHICS AND DISSEMINATION: INSTIGO belongs to category 2 interventional research on humans. This study has been approved by the SUD-EST IV ethics committee and is conducted in accordance with the Declaration of Helsinki and General Data Protection Regulation (GDPR). Study findings will be published in peer-reviewed medical journals. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov, identifier NCT04438681.

Platelet-to-Lymphocyte Ratio Is Associated With Favorable Response to Neoadjuvant Chemotherapy in Triple Negative Breast Cancer: A Study on 120 Patients.

INTRODUCTION: Triple negative breast cancer (TNBC) is highly heterogeneous, but still most of the patients are treated by the anthracycline/taxane-based neoadjuvant therapy (NACT). Tumor-infiltrating lymphocytes (TILs) are a strong predictive and prognostic biomarker in TNBC, however are not always available. Peripheral blood counts, which reflect the systemic inflammatory/immune status, are easier to obtain than TILs. We investigated whether baseline white cell or platelet counts, as well as, Neutrophil-to-Lymphocyte Ratio (NLR) or Platelet-to-Lymphocyte Ratio (PLR) could replace baseline TILs as predictive or prognostic biomarkers in a series of TNBC treated by standard NACT. PATIENTS AND METHODS: One hundred twenty patients uniformly treated by FEC/taxane NACT in a tertiary cancer care center were retrospectively analyzed. The presence of pathological complete response (pCR: ypT0/Tis, ypN0) or the presence of pCR and/small residual disease (ypT0/Tis/T1ab, ypN0) were considered as good responses in data analysis. Baseline/pre-NACT blood count, NLR, PLR and TILs were evaluated as predictors of response, distant recurrence rate and distant recurrence-free survival (DRFS). RESULTS: TILs ≥30% and ≥1.5% were best predictors of pCR and distant recurrence risk, respectively (p = 0.007, p = 0.012). However, in this cohort, pCR status was not significantly associated with recurrence. Only the ensemble of patients with pCR and small residual disease had lower recurrence risk and longer survival DRFS (p = 0.042, p = 0.024, respectively) than the rest of the cohort (larger residual disease). The only parameter which could predict the pCR/small residual disease status was PLR: patients with values lower than 133.25 had significantly higher chance of reaching that status after NACT (p = 0.045). However, no direct correlation could be established between baseline PLR and metastatic recurrence. No correlation either was found between TIL and individual blood counts, or between TILs and NLR or PLR. CONCLUSION: In this cohort, TILs retained their pCR predictive value; however PLR was a better predictor of the ensemble of responses which had good outcome in terms of less distant recurrences or longer DRFS (pCR or small residual disease). Thus, baseline PLR is worth further, prospective investigation together with baseline TILs, as it might indicate a good TNBC response to NACT when TILs are unavailable.

Multicenter randomized phase II study comparing docetaxel plus curcumin versus docetaxel plus placebo in first-line treatment of metastatic castration-resistant prostate cancer.

BACKGROUND: Metastatic castration-resistant prostate cancer (mCRPC) patients have a poor prognosis, and curcumin is known to have antineoplastic properties. On the basis of previous phase I and phase II studies, we investigated whether the association of curcumin with docetaxel could improve prognosis among mCRPC patients. METHODS: A total of 50 mCRPC patients (included from June 2014 to July 2016) treated with docetaxel in association with oral curcumin (6 g/d for 7 days every 3 weeks) versus placebo were included in this double-blind, randomized, phase II study. The primary endpoint was to evaluate the time to progression. Among the secondary endpoints, compliance, overall survival, prostate-specific antigen (PSA) response, safety, curcumin absorption, and quality of life were investigated. An interim analysis was planned in the modified intention-to-treat population with data at 6 months (22 patients per arm). RESULTS: Despite good compliance and a verified absorption of curcumin, no difference was shown for our primary endpoint: progression-free survival (PFS) between the placebo and curcumin groups was, respectively, 5.3 months versus 3.7 months, p = 0.75. Similarly, no difference was observed for the secondary objectives: PSA response rate (p = 0.88), overall survival (p = 0.50), and quality of life (p = 0.49 and p = 0.47). CONCLUSION: Even though our previous studies and data in the literature seemed to support an association between curcumin and cancer therapies in order to improve patient outcome and prognosis, the results from this interim analysis clearly showed that adding curcumin to mCRPC patients' treatment strategies was not efficacious. The study was discontinued on the grounds of futility.

Recurrence biomarkers of triple negative breast cancer treated with neoadjuvant chemotherapy and anti-EGFR antibodies.

To find metastatic recurrence biomarkers of triple-negative breast cancer (TNBC) treated by neoadjuvant chemotherapy and anti-EGFR antibodies (NAT), we evaluated tumor genomic, transcriptomic, and immune features, using MSK-IMPACT assay, gene arrays, Nanostring technology, and TIL assessment on H&E. Six patients experienced a rapid fatal recurrence (RR) and other 6 had later non-fatal recurrences (LR). Before NAT, RR had low expression of 6 MHC class I and 13 MHC class II genes but were enriched in upregulated genes involved in the cell cycle-related pathways. Their TIL number before NAT in RR was very low (<5%) and did not increase after treatment. In post-NAT residual tumors, RR cases showed high expression of SOX2 and CXCR4. Our results indicate that high expression of cell cycle genes, combined with cold immunological phenotype, may predict strong TNBC resistance to NAT and rapid progression after it. This biomarker combination is worth validation in larger studies.

Does regional lymph node irradiation improve the outcome of N0 and pN0 breast cancer?

This study compares the outcome of 76 patients with N0 breast carcinoma, node-negative at axillary lymph node dissection (pN0) after neoadjuvant chemotherapy (NeoCT), treated with (RLNI+, 39 patients) or without (RLNI-, 37 patients) elective regional lymph node areas irradiation. For RLNI- and RLNI+ groups respectively at 10 years, survival without local-regional recurrence was 95% and 91% (p = .59), survival without distant metastasis was 97% and 78% (p = .018) and overall survival was 96% and 75% (p = .013). Clinical size < 4 cm was a strong pronostic factor.

Dietary methionine restriction with FOLFOX regimen as first line therapy of metastatic colorectal cancer: a feasibility study.

UNLABELLED: The methionine (MET) dependency of tumor cells opens interesting perspectives for targeting tumor cells and potentiating chemotherapy treatment, like 5-fluorouracil (5-FU) and platinum compound. Since MET deprivation can individually potentiate the different chemotherapeutic agents used in the 48-hour combined regimen of 5-FU, leucovorin and oxaliplatin (FOLFOX) regimen, we initiated a feasibility study associating dietary MET restriction with the FOLFOX regimen in patients with metastatic colorectal cancer. OBJECTIVES: (i) To evaluate the depletion in the plasma MET concentration, and (ii) to assess the feasibility of this combination. METHODS: Eleven patients were enrolled in this study. They received a median number of 3 two-week cycles of a MET-free diet (3 consecutive days) and FOLFOX6 regimen. RESULTS: The plasma MET concentration was reduced by dietary MET restriction, with a depletion of 58% on the 1st day of MET-free diet. Indeed, we demonstrated the feasibility and good tolerance (nutritional status and toxicity) of the association of a MET-free diet with the FOLFOX regimen. Despite good compliance to the diet, this study revealed the difficulty of administering this combination during further months. Among the 4 patients evaluable for response, 3 experienced a partial response and 1 patient a disease stabilization.

Weight change during chemotherapy changes the prognosis in non metastatic breast cancer for the worse.

BACKGROUND: Weight change during chemotherapy is reported to be associated with a worse prognosis in breast cancer patients, both with weight gain and weight loss. However, most studies were conducted prior to the common use of anthracycline-base chemotherapy and on North American populations with a mean BMI classified as overweight. Our study was aimed to evaluate the prognostic value of weight change during anthracycline-based chemotherapy on non metastatic breast cancer (European population) with a long term follow-up. METHODS: Patients included 111 women diagnosed with early stage breast cancer and locally advanced breast cancer who have been treated by anthracycline-based chemotherapy regimen between 1976 and 1989. The relative percent weight variation (WV) between baseline and postchemotherapy treatment was calculated and categorized into either weight change (WV > 5%) or stable (WV < 5%). The median follow-up was 20.4 years [19.4 - 27.6]. Cox proportional hazard models were used to evaluate any potential association of weight change and known prognostic factors with the time to recurrence and overall survival. RESULTS: Baseline BMI was 24.4 kg/m2 [17.1 - 40.5]. During chemotherapy treatment, 31% of patients presented a notable weight variation which was greater than 5% of their initial weight.In multivariate analyses, weight change (> 5%) was positively associated with an increased risk of both recurrence (RR 2.28; 95% CI: 1.29-4.03) and death (RR 2.11; 95% CI: 1.21-3.66). CONCLUSIONS: Our results suggest that weight change during breast-cancer chemotherapy treatment may be related to poorer prognosis with higher recurrence and higher mortality in comparison to women who maintained their weight.

PERCEPTION Trial protocol: Comparison of predictive and prognostic capacities of neutrophil, lymphocyte, and platelet counts and tumor-infiltrating lymphocytes in triple negative breast cancer.

BACKGROUND: Triple negative breast cancer affects 10% to 20% of all women diagnosed with breast cancer. Due to its characteristics, treatment strategies are limited and metastatic recurrences are common in the first 5 years after treatment. However, not all patients affected by this disease develop metastases. Tumor-infiltrating lymphocytes have shown to be reliable predictive biomarkers of treatment response and metastatic recurrences. However, we need to develop simpler and faster ways to predict response to cytotoxic treatment and the possibility of eventual cancer relapse by identifying new biomarkers. Recently, new studies are emerging, suggesting a predictive role of circulating blood cells in different types of cancer. In this study, we will assess the correlation between tumor-infiltrating lymphocytes and different elements of the blood count in patients diagnosed with triple negative breast cancer. METHODS: The main objective of this study is to evaluate the correlation between the peripheral neutrophil-to-lymphocyte ratio and the amount of tumor-infiltrating lymphocytes, assessed in triple negative breast cancer patients at diagnosis. Secondary objectives include evaluation of the correlation between tumor-infiltrating lymphocytes at diagnosis and the baseline absolute neutrophil, lymphocyte, and platelet counts, as well as the platelet-to-lymphocyte ratio. The triple negative breast cancer patients will be enrolled in the PERCEPTION trial during the first year after the treatment completion. Two supplementary blood tests, at 12 months after the end of treatment and at the time of the first metastatic recurrence, will be performed. DISCUSSION: The discovery of new prognostic and predictive biomarkers is crucial for triple negative breast cancer. We set up the PERCEPTION clinical trial in order to evaluate certain blood counts as early biomarkers and to assess their correlation with tumor-infiltrating lymphocytes. Demonstration of comparative predictive and/or prognostic capacities of peripheral blood counts and tumor-infiltrating lymphocytes would allow introduction of the former as simple and cheap biomarkers in triple negative breast cancer patient management. TRIAL REGISTRATION: The PERCEPTION study has been registered in the French National Agency of Medical Security registry on the 2nd of July 2019 under the number 2019-A01861-56 and in the ClinicalTrials.org registry under the number NCT04068623.

Metastatic breast cancer: overall survival related to successive chemotherapies. What do we gain after the third line?

This retrospective study analyzed, in metastatic breast cancer (MBC), overall survival (OS) related to each subsequent line of chemotherapy (CT). We evaluated 578 patients with a MBC. Among these patients, 558 patients were stratified according to the number of different CT lines received. Median OS decreased from 22.5 to 12.3 months. Nevertheless, survival was rather stable for subsequent lines after the third line of CT around 8 months. In our study, it appeared useful to give several CT lines when possible. Subsequent lines of CT could have a beneficial effect on the survival for some patients with MBC.

Impact of Chemotherapy-induced Menopause in Women of Childbearing Age With Non-metastatic Breast Cancer - Preliminary Results From the MENOCOR Study.

BACKGROUND: Young patients with breast cancer treated with chemotherapy can experience ovarian failure, which can lead to chemotherapy-induced menopause (CIM) impacting the quality of life (QoL). A prospective study was set out to evaluate the impact of CIM on QoL in women of childbearing age with non-metastatic breast cancer, and this article reports results of the interim analysis conducted to evaluate feasibility and to see preliminary results. PATIENTS AND METHODS: A total of 58 women (age, 18-46 years) with newly diagnosed breast cancer and treated with chemotherapy were eligible. QoL was assessed by self-administered questionnaires (Quality of Life Questionnaire-Core 30 [QLQ-C30], Quality of Life Questionnaire-Breast 23 [QLQ-BR23], and Kupperman index) and hormonal variations (anti-Müllerian hormone [AMH], follicle-stimulating hormone, and estradiol) were explored. We compared patients with ≥ 12 months amenorrhea (CIM) (n = 41) to patients with < 12 months of amenorrhea (non-CIM) (n = 17). RESULTS: A good inclusion rate (approximately 4/month) and sufficient data enabled us to perform this analysis. QLQ-C30 failed to show any difference between CIM and non-CIM patients (P = .5). In contrast, at 6 months post-chemotherapy, CIM patients tended to have lower QoL as shown by QLQ-BR23 (P = .16) and more severe climacteric symptoms (P = .01). Regarding hormonal variations, AMH pre-treatment level was higher in non-CIM patients (P = .0032). We also noted that CIM patients were older (P = .00013), had shorter menstruation cycle (P = .082), and experienced faster amenorrhea (P = .088). CONCLUSIONS: The study is technically feasible, and our preliminary results underline that age in association with pre-treatment AMH level could be helpful to predict ovarian function. QLQ-BR23 seemed to be stronger, more precise, and appropriate to evaluate QoL changes in patients with breast cancer than the QLQ-C30.
