RESUMEN

PURPOSE: Anemia is common in oncology and negatively impacts quality of life. However, there is lack of knowledge about iron deficiency (ID) epidemiology. The aim of this study was to prospectively assess iron status in patients with locally advanced or metastatic cancer beginning chemotherapy. METHODS: In this prospective, multicenter cohort study, anemia and ID were evaluated in patients with locally advanced or metastatic solid tumors and lymphoma before starting chemotherapy. Blood samples were collected at inclusion (W0), 6 weeks (W6), and 12 weeks (W12). Prevalence was evaluated in the general population, according to tumor location and was correlated with tumor response. RESULTS: One hundred twenty-nine patients were enrolled between 2013 and 2015; 119 had solid tumors and 10 lymphomas. At W0, there were no significant difference between locations with a prevalence around 50-60% (range 47.2-70.4%) and only a trend for colorectal cancer (70.4%, P = 0.069) due to a higher prevalence of absolute ID (18.5%). Prevalence of ID+ decreased between W0 and W6 and remained stable until W12 due to the proportion of patients with ID and without anemia. However, anemia prevalence increased during W0 and W6 and remained stable to W6 from W12 due to patients with anemia but without ID. A significant correlation between tumor response and ID prevalence was found (P = 0.036). CONCLUSIONS: We confirm the high prevalence of ID and anemia in cancer patients. ID status is correlated to tumor response providing a strong rationale for iron monitoring during cancer management.

RESUMEN

BACKGROUND: Elderly patients with metastatic breast cancer have a prognosis and outcome that may be dependent on a host of factors. PATIENTS AND METHODS: We retrospectively analyzed 401 female breast cancer patients who developed metastatic disease after the age of 70 years in order to define potential prognostic factors for specific survival at the time of first recurrence. RESULTS: With a median follow-up of 60 months from the time of recurrence, the median specific survival was 21.0 months (95% CI 17.0-23.0). In multivariate analysis we demonstrated that negative hormonal receptor status (p = 0.002), presence of positive lymph nodes at initial cancer diagnosis (hazard ratio, HR = 1.37; 95% CI 1.07-1.75; p = 0.01), site of metastasis (p < 10(-4)) and metastasis-free interval (HR = 0.99; 95% CI 0.95-0.99; p = 0.008) constituted unfavorable independent prognostic factors able to predict specific survival from the time of metastatic occurrence. Age at initial diagnosis, Scarff-Bloom Richardson grade and adjuvant treatments were significant only in univariate analysis. CONCLUSION: These survival prognostic factors associated with the use of a specific geriatric questionnaire to assess frailty may assist physicians in evaluating the patient's survival potential and choose a tailored treatment to this cancer population.

RESUMEN

BACKGROUND: There is no proven benefit of adjuvant treatment of uterine sarcoma (US). SARCGYN phase III study compared adjuvant polychemotherapy followed by pelvic radiotherapy (RT) (arm A) versus RT alone (arm B) conducted to detect an increase ≥ 20% of 3-year PFS. METHODS: Patients with FIGO stage ≤ III US, physiological age ≤ 65 years; chemotherapy: four cycles of doxorubicin 50 mg/m² d1, ifosfamide 3 g/m²/day d1-2, cisplatin 75 mg/m² d3, (API) + G-CSF q 3 weeks. Study was stopped because of lack of recruitment. RESULTS: Eighty-one patients were included: 39 in arm A and 42 in arm B; 52 stage I, 16 stage II, 13 stage III; 53 leiomyosarcomas, 9 undifferenciated sarcomas, 19 carcinosarcomas. Gr 3-4 toxicity during API (/37 patients): thrombopenia (76%), febrile neutropenia (22%) with two toxic deaths; renal gr 3 (1 patient). After a median follow-up of 4.3 years, 41/81 patients recurred, 15 in arm A, 26 in arm B. The 3 years DFS is 55% in arm A, 41% in arm B (P = 0.048). The 3-year overall survival (OS) is 81% in arm A and 69% in arm B (P = 0.41). CONCLUSION: API adjuvant CT statistically increases the 3 year-DFS of patients with US.

RESUMEN

BACKGROUND: The CALYPSO phase III trial compared CD (carboplatin-pegylated liposomal doxorubicin (PLD)) with CP (carboplatin-paclitaxel) in patients with platinum-sensitive recurrent ovarian cancer (ROC). Overall survival (OS) data are now mature. METHODS: Women with ROC relapsing > 6 months after first- or second-line therapy were randomised to CD or CP for six cycles in this international, open-label, non-inferiority trial. The primary endpoint was progression-free survival. The OS analysis is presented here. RESULTS: A total of 976 patients were randomised (467 to CD and 509 to CP). With a median follow-up of 49 months, no statistically significant difference was observed between arms in OS (hazard ratio = 0.99 (95% confidence interval 0.85, 1.16); log-rank P = 0.94). Median survival times were 30.7 months (CD) and 33.0 months (CP). No statistically significant difference in OS was observed between arms in predetermined subgroups according to age, body mass index, treatment-free interval, measurable disease, number of lines of prior chemotherapy, or performance status. Post-study cross-over was imbalanced between arms, with a greater proportion of patients randomised to CP receiving post-study PLD (68%) than patients randomised to CD receiving post-study paclitaxel (43%; P < 0.001). CONCLUSION: Carboplatin-PLD led to delayed progression and similar OS compared with carboplatin-paclitaxel in platinum-sensitive ROC.

RESUMEN

BACKGROUND: Platinum rechallenge or weekly topotecan in combination have not been evaluated in randomized trials for resistant recurrent ovarian cancer (ROC). METHODS: Patients with ROC after first- or second-line treatment including a platinum and taxane and progression within 6 months were randomized to weekly paclitaxel (wP, 80 mg/m(2)/week) alone or in combination with carboplatin (C, area under the curve of 5 mg/ml/min every 4 weeks) or weekly topotecan (wT, 3 mg/m(2)/week). Primary end point was progression-free survival (PFS) comparing wP and combination therapy. RESULTS: Patients (n = 165) received a median three cycles in each arm. Nonhematologic toxicity was not different, except increased hypersensitivity reactions with wP + C. Grade 3-4 hematologic toxic effects with wP, wP + C, and wP + wT, respectively, were neutropenia in 13%, 54%, and 42%; febrile neutropenia in 0%, 4%, and 5%; and anemia in 6%, 19%, and 29%. Response rates were 35%, 37%, and 39%, and median PFS times were 3.7, 4.8, and 5.4 months, respectively. PFS was not significantly different among the treatment arms [hazard ratio (HR) 0.922; 95% confidence interval (CI) 0.765-1.111; P = 0.46] or between monotherapy and combination therapy (HR 0.951; 95% CI 0.686-1.318; P = 0.76). CONCLUSIONS: Combination chemotherapy in platinum-resistant ROC was more toxic than weekly paclitaxel and did not significantly prolong PFS.

RESUMEN

BACKGROUND: Sorafenib is an oral anticancer agent targeting Ras-dependent signaling and angiogenic pathways. A phase I trial demonstrated that the combination of gemcitabine and sorafenib was well tolerated and had activity in advanced pancreatic cancer (APC) patients. The BAYPAN study was a multicentric, placebo-controlled, double-blind, randomized phase III trial comparing gemcitabine/sorafenib and gemcitabine/placebo in the treatment of APC. PATIENTS AND METHODS: The patient eligibility criteria were locally advanced or metastatic pancreatic adenocarcinoma, no prior therapy for advanced disease and a performance status of zero to two. The primary end point was progression-free survival (PFS). The patients received gemcitabine 1000 mg/m(2) i.v., weekly seven times followed by 1 rest week, then weekly three times every 4 weeks plus sorafenib 200 mg or placebo, two tablets p.o., twice daily continuously. RESULTS: Between December 2006 and September 2009, 104 patients were enrolled on the study (52 pts in each arm) and 102 patients were treated. The median and the 6-month PFS were 5.7 months and 48% for gemcitabine/placebo and 3.8 months and 33% for gemcitabine/sorafenib (P = 0.902, stratified log-rank test), respectively. The median overall survivals were 9.2 and 8 months, respectively (P = 0.231, log-rank test). The overall response rates were similar (19 and 23%, respectively). CONCLUSION: The addition of sorafenib to gemcitabine does not improve PFS in APC patients.

RESUMEN

BACKGROUND: Very effective trastuzumab-based primary systemic therapy (PST) can be proposed for conservative surgery purpose to human epidermal growth factor receptor 2 (HER2)-positive breast cancer (HER2+BC). Long-term follow-up (LTFU) warrants further data. PATIENTS AND METHODS: LTFU of patients, with stage II/III HER2+BC, treated by trastuzumab associated with docetaxel (Taxotere(®)) and/or carboplatin used as anthracycline-free PST was studied. RESULTS: Among 135 patients, with a median follow-up of 48.3 months [95% confidence interval (CI) 45.3-52.4 months], the relapse-free survival (RFS) rate was 73.2% (95% CI 63.76% to 80.55%) while the overall survival (OS) rate was 91.87% (95% CI 84.23% to 95.90%). Adjuvant trastuzumab favorably influenced RFS in univariate analysis while the pathological nodal invasion unfavorably influenced RFS [Cox multivariate analysis (hazard ratio = 2.80, 95% CI 1.36-5.76, P = 0.0052)] and OS. Cardiac toxicity was minor (2.2% transient, reversible asymptomatic decrease in left ventricular ejection fraction). CONCLUSION: This is the first report of LTFU showing that anthracycline-free trastuzumab-based PST combined either with docetaxel and/or carboplatin can achieve, without cardiac toxicity, very competitive results in terms of pathological complete response, RFS and OS, in HER2+BC. The choice of this schedule could be proposed to patients with vascular contraindication for anthracyclines or because patient's or physician's preference for a taxane-only schedule.

RESUMEN

BACKGROUND: Despite current treatment options, metastatic breast cancer (MBC) remains essentially incurable, requiring research on new drugs or combinations to improve survival and quality of life. PATIENTS AND METHODS: This phase I study was designed to define the maximum-tolerated dose (MTD), dose-limiting toxicity (DLT) and recommended dose of all-oral tegafur-uracil (UFT)/folinic acid combined with vinorelbine as chemotherapy for MBC. Starting doses were 40 mg/m(2)/week of oral vinorelbine administered continuously and 250 mg/m(2)/day of UFT plus 90 mg/day of folinic acid from day 1 to day 28, followed by a 1-week rest period. RESULTS: Ten patients were included. Eight were evaluable for toxicity and antitumor response. The second dose level was shown to be the MTD. At this dose, 2 out of 5 patients receiving oral vinorelbine at 40 mg/m(2)/week and UFT at 300 mg/m(2)/day developed DLT consisting of grade 3 asthenia and grade 3 nausea despite standard prophylaxis. Other toxicities were grade 1 diarrhea and anemia. There were no treatment-related deaths. CONCLUSIONS: The recommended dose for this combination seems to be the first dose level. A stable response was observed for 6 patients (average 33 weeks). This combination appears to be well-tolerated and offers an alternative to intravenous chemotherapy.

RESUMEN

BACKGROUND: The role of aromatase inhibitors (AIs) and their impact on estradiol (E(2)) levels remain unknown in male breast cancer (MBC) patients. PATIENTS AND METHODS: MBC patients with metastatic disease and those treated with AIs were selected from the breast cancer database of the Centre Antoine-Lacassagne (Nice, France). Sex hormone levels were retrospectively assessed on serum samples from our institutional serum bank. RESULTS: Fifteen patients entered the study. Two patients (13%) had complete response, four patients (27%) had partial response, two patients (13%) had stable disease and seven patients (47%) had progressive disease. The median progression-free survival and overall survival were 4.4 months [95% confidence interval (CI) 0.1-8.6] and 33 months (95% CI 18.4-47.6), respectively. All assessable patients (n = 6) had E(2) levels less than the lower limit of the assay during AI treatment. Among them, three had partial response, one had stable disease and two had progressive disease. A large increase in follicle-stimulating hormone, luteinizing hormone and E(2) levels was observed in one responding patient at progression. CONCLUSIONS: AIs are active in MBC patients. This activity is correlated with a significant reduction in E(2) levels. Secondary resistance is in part related to a deleterious feedback loop resulting in a significant increase in substrate for aromatization.

RESUMEN

BACKGROUND: This phase II study evaluated the clinical benefit of pegylated liposomal doxorubicin (PLD) and docetaxel (Taxotere) as first-line therapy for metastatic breast cancer (MBC). PATIENTS AND METHODS: MBC patients were enrolled to receive six cycles of PLD 35 mg/m2 (day 1) and docetaxel 40 mg/m2 (days 1 and 15), every 28 days (group A). Because of unacceptable toxic effects, doses were modified to PLD 30 mg/m2 (day 1) and docetaxel 75 mg/m2 (day 2), every 3 weeks (group B). The primary end point was clinical benefit. RESULTS: Sixty-seven patients were included (group A, 53; group B, 14). In both groups, the median number of cycles delivered was 4 and the overall dose intensity was 82% for docetaxel and 71% for PLD. In group A, main toxic effects were hematologic, palmar-plantar erythrodysesthesia (PPE), and stomatitis. In group B, higher rates of grade 3-4 PPE, febrile neutropenia, and hematologic toxic effects were reported. The rate of clinical benefit was 47%. Among patients with a measurable disease, 49% achieved a partial response, 27% had a stable disease, and 13% progressed, according to RECIST criteria. CONCLUSION: The combination of PLD and docetaxel delivered at planned doses in this study yields unacceptable toxicity and should not be used routinely in patients with MBC.

RESUMEN

OBJECTIVE: Cisplatin (Cp) plus topotecan (Tc) is the first combination chemotherapy to demonstrate a survival advantage over cisplatin alone in advanced cervical cancer. Combining Cp and Tc with an epidermal growth factor receptor (EGFR) inhibitor such as cetuximab (Ce) may increase the activity of chemotherapy. METHODS: Patients with advanced cervical squamous cell cancer or adenocarcinoma and at least one measurable target received intravenous Cp 50 mg/m(2) on day 1 plus Tc 0.75 mg/m(2)/day from days 1 to 3 every 3 weeks combined with Ce (initial dose of 400 mg/m(2) followed by subsequent weekly dose of 250 mg/m(2)). Objective response rate according to RECIST criteria was the primary end point; safety, progression free survival (PFS) and overall survival (OS) were secondary end points. RESULTS: Between April and July 2007, 19 out of the 44 planned patients were accrued before the study was stopped early due to excessive toxicity. The most frequent adverse event was severe myelosuppression with grades 3-4 neutropenia (72%), grades 3-4 thrombocytopenia (61%), and grade 3 anemia (44.5%). The main grades 3-4 non-hematologic toxicities were infection (39%) and febrile neutropenia (28%), skin reactions (22%), renal toxicity (11%), and pulmonary embolism (11%). Five (28%) patients died during the treatment including 3 deaths related to treatment toxicity. Six (32%) evaluable patients achieved a partial response. The median times of PFS and OS were 172 and 220 days, respectively. CONCLUSION: In this phase II trial, the combination Cp-Tc-Ce induced a high rate of serious adverse and/or fatal events at standard dose and schedule. Cetuximab plus platinum-based combination chemotherapy should be further explored with caution in the future in advanced cervix cancer.

RESUMEN

BACKGROUND: Treatment of metastatic breast cancer (MBC) remains palliative. Patients with MBC represent a heterogeneous group whose prognosis and outcome may be dependent on host factors. The purpose of the present study was dual: first, to draw up a list of factors easily available in everyday clinical practice requiring no sophisticated or costly methods and second, to provide results from a large cohort of women who underwent diagnostic and treatment at a single institution. PATIENTS AND METHODS: From 1975 to 2005, a total of 1,038 women with MBC during their follow-up were included in this retrospective analysis. Patients were subsequently assigned to five groups according to the period of metastatic diagnosis. RESULTS: It is shown that age at initial diagnosis, hormonal receptor status and site of metastasis are the most relevant prognostic factors for predicting survival from the time of metastastic occurrence. It is also shown that a metastasis-free interval is an easily and immediately available multifactorial prognostic index reflecting the multiparametric variability of the disease. CONCLUSION: These fundamental observations may assist physicians in evaluating the survival potential of patients and in directing them toward the appropriate therapeutic decision.

RESUMEN

Topotecan is indicated in the treatment of advanced-stage ovarian cancers refractory to prior platinum-based regimen. The aim of this study was to compare the standard therapeutic strategy with a novel strategy of weekly administration of topotecan. The primary endpoints were dose density and overall tolerance. This retrospective cohort study included patients with ovarian cancer in relapse. During a first period (1998-2001), 24 patients received the standard topotecan dose of 1.5 mg/m(2)/day for 5 consecutive days with a 3-week interval between each treatment course. During a second period (2003-2006), 21 patients received a weekly topotecan dose of 4 mg/m(2) for 3 weeks out of every 4. Grades III and IV haematological toxicities were more frequent with the standard strategy (p < 0.05), even after adjustment of the prescription of erythropoietin and G-CSF. With the weekly strategy, an increase in dose density and a reduction in the number of delayed doses were observed. No significant difference between the 2 strategies was found in terms of response to the treatment and specific survival. This study suggests that the weekly administration of topotecan 4 mg/m(2), for 3 weeks out of every 4, results in a better maintenance of dose density and a reduction in haematological toxicity.

RESUMEN

OBJECTIVES: To investigate whether some aspects of patient or tumor characteristics influence the timing of local recurrence (LR) in breast cancer treated conservatively, and to assess the impact of the timing of LR on patient outcome. METHODS: A retrospective analysis was conducted on patients treated with conservative breast surgery followed by radiotherapy for breast carcinoma who developed LR. Out of 2,008 cases treated in our Institute between 1977 and 2002, 180 ipsilateral LR were observed. Of these, 46 LR were observed within 36 months after treatment, called early local recurrence (ELR), 44 developed between 37 and 60 months, called medium local recurrence (MLR), and 90 occurred after 60 months, called late local recurrence (LLR). Patient and tumor characteristics were analyzed in the 2 groups and compared. RESULTS: Primary tumors >20 mm were more frequently found in patients with ELR (31%) than in patients with LLR (17%, p = 0.047). Grade 3 tumors were more often encountered in patients with ELR than in patients with LLR (27 versus 7%, p = 0.0002). Patients with ELR more frequently had tumors with negative estrogen receptors than patients with LLR (37% versus 6%, p < 0.0001). There was no statistically significant difference in the axillary lymph node (LN) status between patients with ELR and those with LLR (35 and 23% of positive LN, respectively, p = 0.24). Tumor size, grade, LN status, hormone receptors and the timing of LR affected the specific survival (SS) from initial surgery. On multivariate analysis, only LN status and the timing of LR retained an independent prognostic value, with an odds ratio of 6.7 for ELR. After LR, the SS was also influenced by all of the above factors, and on multivariate analysis, LN status, hormone receptors and the timing of LR were independent predictors with an odds ratio of SS of 2.50 in case of ELR (p = 0.006). The 5-year SS after LR for ELR, MLR and LLR were 55.8, 74.8 and 79.5%, respectively. CONCLUSIONS: Unfavorable tumor characteristics such as big size, high grade, lack of hormone receptors, but not LN status, were associated with ELR. These findings suggest that patients with such aggressive tumor characteristics who do not recur early will have a lower risk of LLR than patients with more favorable factors.

RESUMEN

The objective of the study was to determine outcome and satisfaction of cancer patients treated by home-infusions of biphosphonates. 107 patients entered the study and 97 of them chose to receive infusions of zoledronic acid (Z) in the home setting. Patient satisfaction and quality of care (QoC) were assessed by a 22-item questionnaire. Changes from baseline were determined for bone pain using a 0-10 cm visual analogue scale pain score (VAS). Patients expressed a high level of satisfaction specifically with regard to nursing care. Seventy patients experienced a significant decrease in the median pain score during the home-therapy phase not due to an increased use of analgesic therapy (P = 0.03). Z was well tolerated with no major adverse events. The authors conclude that home infusions of biphosphonates, on the condition that the supportive care team is well-organized, is a safe procedure that could be advantageous for patients by increasing satisfaction and compliance with treatment.

RESUMEN

Breast carcinoma metastasize more frequently to the bone, liver lung and brain as compared to other anatomical sites. As such, advanced breast tumours with secondaries involving the rarer sites often pose when a therapeutic challenge for the clinician to find a good balance between offering the most effective therapy and its potential toxicity. We report the first case of tongue metastasis from breast cancer that was successfully treated with interstitial brachytherapy, resulting in good local control and no severe side effects.

RESUMEN

Treating patients with anthracycline- and taxane-pretreated metastatic breast cancer (MBC) represents a significant challenge to oncologists. The tumour-activated oral fluoropyrimidine, capecitabine, is the only treatment approved for these patients. Our study evaluated the efficacy, safety and impact on quality of life (QOL) of capecitabine in this setting. Patients (n=126) with anthracycline- and taxane-pretreated metastatic breast cancer received capecitabine 1250 mg/m(2) twice daily, days 1-14, followed by a 7-day rest period. Median time to progression was 4.9 months (95% Confidence Interval (CI): 4.0-6.4). Thirty-five patients (28%) achieved an objective response (95% CI: 20-36%), including five (4%) complete responses. Median overall survival was 15.2 months (95% CI: 13.5-19.6 months). Capecitabine demonstrated a favourable safety profile, with a low incidence of treatment-related grade 3/4 adverse events. The most common adverse events were hand-foot syndrome and gastrointestinal effects. QOL assessment showed that capecitabine treatment was associated with an increase in mean Global Health Score. Capecitabine is active, well tolerated and improves the QOL of patients with anthracycline- and taxane-pretreated metastatic breast cancer. Based on the consistently high activity demonstrated in clinical trials, capecitabine has become the reference treatment in this setting.

RESUMEN

PURPOSE: To determine the outcome of patients with positive margins after lumpectomy for breast cancer and to address the issue of the relationship between local recurrences and distant metastasis in the absence of chemotherapy. METHODS AND MATERIALS: Among 3697 patients with primary breast cancer, we retrospectively analyzed 152 patients who had undergone conservative surgery with axillary dissection, had infiltrating carcinomas with positive margins, were node-negative, and received radiotherapy without chemotherapy. One-third received hormonal therapy. Endpoints were local failure and distant metastasis. Median follow-up was 72 months. RESULTS: Five- and 10-year recurrence-free survival were 0.80 and 0.71 respectively for local recurrences, and 0.85 and 0.73 respectively for metastasis. Infiltrating carcinoma on the margins was associated with early local relapse as opposed to intraductal carcinoma. Local and distant recurrences had similar patterns of yearly-event probabilities. Hazard of relapsing from metastasis was 2.5 times higher after a local recurrence. In the multivariate analysis, negative estrogen receptors (ER-)(p = 0.0012), histologic multifocality (p = 0.0028), and no hormonal therapy (p = 0.017) predicted local relapses, while ER- (p = 0.004) and pathologic grade (p = 0.009) predicted metastasis. Hormonal therapy did not prevent early local recurrences. CONCLUSION: In this population, reexcision is advisable for local purposes and because the data support the hypothesis that local and distant recurrences are tightly connected.
