A Descriptive Study of 103 Primary Cutaneous B-Cell Lymphomas: Clinical and Pathological Characteristics and Treatment from the Spanish Lymphoma Oncology Group (GOTEL).

Primary cutaneous B-cell lymphomas (PCBCLs) are B-cell lymphomas that can occur in the skin without evidence of extracutaneous involvement. The 2005 WHO/EORTC classification of cutaneous lymphomas and its 2018 update have distinguished three main categories based on clinicopathological, immunohistochemical, and genetic characteristics: primary cutaneous marginal zone lymphoma (PCMZL), primary cutaneous follicle centre lymphoma (PCFCL), and primary cutaneous diffuse large B-cell lymphoma, leg type (PCDLBCL-LT). PCMZL and PCFCL are clinically indolent, while PCDLBCL-LT is an aggressive lymphoma. Due to its low incidence and lack of prospective studies, it is difficult to establish a standard treatment for each subgroup. The objective of our study was to describe the clinical and pathological characteristics of 103 patients with cutaneous B-cell lymphoma from 12 centres belonging to the Spanish Lymphoma Oncology Group. The median age was 53 years (40-65). According to skin extension, 62% had single-site lymphoma, 17% had regional lymphoma, and 20% had multifocal lymphoma. Histology: 66% had PCMZL, 26% had PCFCL, and 8% had PCDLBCL-LT. Twenty-three percent of the patients were treated exclusively with surgery, 26% with radiotherapy only, 21% with surgery plus radiotherapy, 10% with polychemotherapy, and 5% with rituximab monotherapy. Overall, 96% of patients achieved a complete response, and 44% subsequently relapsed, most of them relapsing either locally or regionally. The 10-year OS was 94.5% for the entire cohort, 98% for the PCMZL cohort, 95% for the PCFCL cohort, and 85.7% for the PCDLBCL-LT cohort. Our data are comparable to those of other published series, except for the high frequency of PCMZL. The expected heterogeneity in therapeutic management has been observed.

Prognostic factors for survival with nab-paclitaxel plus gemcitabine in metastatic pancreatic cancer in real-life practice: the ANICE-PaC study.

BACKGROUND: Treatment with nab-paclitaxel plus gemcitabine increases survival in patients with metastatic pancreatic cancer. However, the assessment of treatment efficacy and safety in non-selected patients in a real-life setting may provide useful information to support decision-making processes in routine practice. METHODS: Retrospective, multicenter study including patients with metastatic pancreatic cancer, who started first-line treatment with nab-paclitaxel plus gemcitabine between December 2013 and June 2015 according to routine clinical practice. In addition to describing the treatment pattern, overall survival (OS) and progression-free survival (PFS) were assessed for the total sample and the exploratory subgroups based on the treatment and patients' clinical characteristics. RESULTS: All 210 eligible patients had a median age of 65.0 years (range 37-81). Metastatic pancreatic adenocarcinoma was recurrent in 46 (21.9%) patients and de novo in 164 (78.1%); 38 (18%) patients had a biliary stent. At baseline, 33 (18.1%) patients had an ECOG performance status ≥2. Patients received a median of four cycles of treatment (range 1-21), with a median duration of 3.5 months; 137 (65.2%) patients had a dose reduction of nab-paclitaxel and/or gemcitabine during treatment, and 33 (17.2%) discontinued treatment due to toxicity. Relative dose intensity (RDI) for nab-paclitaxel, gemcitabine, and the combined treatment was 66.7%. Median OS was 7.2 months (95% CI 6.0-8.5), and median PFS was 5.0 months (95% CI 4.3-5.9); 50 patients achieved either a partial or complete response (ORR 24.6%). OS was influenced by baseline ECOG PS, NLR and CA 19.9, but not by age ≥ 70 years and/or the presence of hepatobiliary stent or RDI < 85%. All included variables, computed as dichotomous, showed a significant contribution to the Cox regression model to build a nomogram for predicting survival in these patients: baseline ECOG 0-1 vs. 2-3 (p = 0.030), baseline NLR > 3 vs. ≤ 3 (p = 0.043), and baseline CA 19.9 > 37 U/mL vs. ≤37 U/mL (p = 0.004). CONCLUSIONS: Nab-Paclitaxel plus gemcitabine remain effective in a real-life setting, despite the high burden of dose reductions and poorer performance of these patients. A nomogram to predict survival using baseline ECOG performance status, NLR and CA 19.9 is proposed.

Factors Associated with the Selection of First-line Bevacizumab plus Chemotherapy and Clinical Response in HER2-negative Metastatic Breast Cancer: ONCOSUR AVALOX Study.

AIM: To evaluate factors associated with the selection of first-line bevacizumab plus chemotherapy and clinical response in HER2-negative metastatic breast cancer (MBC) in clinical practice in Spain. PATIENTS AND METHODS: All consecutive adult female patients with HER2-negative MBC who had received first-line bevacizumab plus chemotherapy for at least 3 months were enrolled in the present study. RESULTS: A total of 292 evaluable patients were included; 25% had triple-negative breast cancer (TNBC) and 75% had hormone receptor-positive breast cancer (HRPBC). Nearly 40% of patients had ≥3 metastatic sites, mainly located in the bone (48%) and liver (40%). Bevacizumab was mostly combined with paclitaxel (67.1%). ER-positive tumors were only identified as an independent factor associated with the choice of treatment (odds ratio (OR): 0.538; p=0.02). The overall response rate (ORR) was 63.7% (TNBC: 57.5%; HRPBC: 65.9%). Patients aged 36-50 years (OR: 3.03; p=0.028) and those with metastases at sites other than the bone (OR: 0.38; p=0.001) and ≥3 metastatic sites (OR: 1.41; p=0.018) were more likely to achieve objective responses. CONCLUSION: First-line bevacizumab plus chemotherapy, mainly paclitaxel, is an effective and well-tolerated treatment option for HER2-negative MBC, particularly in more aggressive disease.

State-of-the-art of bone marrow imaging in multiple myeloma.

PURPOSE OF REVIEW: Multiple myeloma is a common hematological malignancy arising in the bone marrow. Bone lesions were initially depicted with conventional radiography, although recently F-FDG PET/CT and MRI are recognized as having a clear role in the initial workup and in the evaluation of therapy response. RECENT FINDINGS: Tumor development produces osteolysis and expansive lesions. Although tumor burden and extent are key prognostic factors, different cancer hallmarks can also be evaluated in vivo through noninvasive imaging. SUMMARY: This imaging-based virtual biopsy approach might be useful to define several relevant prognostic markers, such as angiogenesis, cellularity, metabolic trapping and bone morphology and elasticity, both before and during treatment, to predict tumor behavior and the early effect of therapy.

Association between serum levels of C-reactive protein and response to treatment of chemotherapy-induced anemia in patients with solid tumors: a multicenter, prospective, observational study.

Our objective was to determine the association between C-reactive protein (CRP) levels at initiation of anemia treatment and response in solid tumor patients with chemotherapy (CT)-induced anemia. This was a multicenter, prospective, observational study which included adult patients with solid tumor initiating treatment for CT-induced anemia. Data were collected up to 16 weeks, or until premature discontinuation. We included 98 patients (median age 62.5 years, 64 % males, 57 % with ECOG 0-1, 85.7 % at stages III-IV and 54.1 % undergoing palliative CT). Mean (SD) Hb levels at baseline were 10.3 (0.9) g/dL (85.7 % < 11 g/dL) and median (Q1; Q3) CRP was 16.4 mg/L (3.9; 77.8) (68 % ≥ 5 mg/L). A total of 96 % of patients initiated erythropoiesis-stimulating agents (ESA) and iron supplementation; 4 % initiated iron monotherapy. After a median of 85 days, 65 % of patients had Hb ≥ 11 g/dL (in absence of transfusion) (mean change: +0.86 g/dL, 95 % confidence interval (CI) 0.53-1.19). A total of 8 patients required transfusion. A significant correlation (r = -0.39, p = 0.003) was observed between baseline CRP and final Hb levels. In the multivariate linear regression analysis, the independent predictors of higher final Hb levels were a high baseline Hb (adjusted ß = +0.69 g/dL for each g/dL of baseline Hb, 95 % CI 0.17-1.21) and a low log baseline CRP (-0.62 for each log mg/L, 95 %CI -1.22 to -0.02). Our results suggest that, in patients with solid tumors and CT-induced anemia, high CRP levels at treatment initiation predict a poor response to treatment with ESA and iron, independently from anemia severity at therapy initiation and from other patient and disease characteristics.

Effectiveness of darbepoetin alfa in a cohort of oncology patients with chemotherapy-induced anaemia. Relationship between variation in three fatigue-specific quality of life questionnaire scores and change in haemoglobin level.

BACKGROUND: Cancer patients with chemotherapy-induced anaemia (CIA) often experience cancer-related fatigue (CRF). Darbepoetin alfa (DA) once every 3 weeks (q3w) is an effective and well tolerated erythropoiesis-stimulating agent. This study evaluated DA effectiveness and psychometric properties of the Functional Assessment of Cancer Therapy Fatigue-Subscale (FACT-F) and the Fatigue Symptom Inventory (FSI) in CIA patients. METHODS: This was a single-centre, prospective study in 100 patients with solid tumour and moderate to severe CRF (visual analogue scale [VAS-F] ≥ 30 mm) who received DA 500 µg q3w during chemotherapy (CT). Clinical data, VAS-F, FACT-F and FSI scores were collected at the beginning and at the end of CT (EOCT). RESULTS: Mean age was 62.7 years (SD: 12.1), 53.0% were women, 92.0% had ECOG 0-1 and 64% had stage IV tumours. Mean haemoglobin (Hb) significantly increased from baseline 10.2 g/dl to 11.3 g/dl at EOCT. Sixty-five percent of patients showed haematopoietic response at any study point (Hb ≥ 12 g/dl or an increase of ≥ 2 g/dl from baseline), 77% achieved Hb ≥ 11 g/dl and 7% required blood transfusions from week 5 to EOCT. CRF improvement was demonstrated by significant changes in VAS-F, FACT-F and FSI scores (decreases of 21.54, 3.56 and 12.97 points, respectively). FACT-F and FSI questionnaires showed high internal consistency (Cronbach's alpha of 0.98 and 0.98 for FACT-F and FSI, respectively, at the end of study) and satisfactory intra-class coefficients (FACT-F, r=0.73; FSI, r=0.83). There were significant correlations between scores and Hb changes (FACT-F, r=-0.44; FSI, r=-0.54). CONCLUSIONS: DA 500 µg q3w showed effectiveness in improving Hb and inducing a clinically significant decrease in CRF of patients with solid tumours undergoing CT. The three instruments, VAS-F, FACT-F and FSI, could be suitable for assessing CRF.

Autonomic nervous system dysfunction in advanced systolic heart failure.

BACKGROUND: An alteration of the autonomic nervous system has been described in heart failure (HF). The aim of this study was to assess, compare and relate the impairment of both arms of the autonomic nervous systems, the sympathetic and parasympathetic (SNS and PNS) in a same group of patients. METHODS: We analyzed 23 patients with advanced HF (NYHA III-IV/IV and IV/IV) and EF<35% who were on the waiting list for heart transplantation. We assessed the SNS by determining cardiac uptake of (123)I metaiodobenzylguanidine, and analyzed the heart mediastinum rate (HMR) and the myocardial washout rate (WR). The PNS was assessed by 24-hour Holter ECG recording and subsequent analyses of heart rate turbulence (HRT) in which turbulence onset (TO) and turbulence slope (TS) were determined. RESULTS: In the study of the SNS, HMR values were 1.32 ± 0.12, and WR 0.36 ± 0.1. Higher creatinine levels were associated with a lower WR (r=-0.604; p=0.02). In the study of the SNP, TO was higher the lower the LVEF (r=-0.410; p=0.052), and age was associated with a lower TS (r=-0.4; p=0.059). In the study of the relationships between the SNS and PNS, HMR was correlated in a nearly significant manner with TO (r=-0.399; p=0.059) and WR with TS (r=-0.447; p=0.033). CONCLUSIONS: In stable patients with advanced HF (NYHA III-IV and IV/IV), a significant and parallel impairment occurs in both arms of the autonomic nervous system. This could have prognostic implications and would help to prioritize patients on the waiting list for heart transplantation.

Adjuvant docetaxel for high-risk, node-negative breast cancer.

BACKGROUND: A regimen of docetaxel, doxorubicin, and cyclophosphamide (TAC) is superior to a regimen of fluorouracil, doxorubicin, and cyclophosphamide (FAC) when used as adjuvant therapy in women with node-positive breast cancer. The value of taxanes in the treatment of node-negative disease has not been determined. METHODS: We randomly assigned 1060 women with axillary-node-negative breast cancer and at least one high-risk factor for recurrence (according to the 1998 St. Gallen criteria) to treatment with TAC or FAC every 3 weeks for six cycles after surgery. The primary end point was disease-free survival after at least 5 years of follow-up. Secondary end points included overall survival and toxicity. RESULTS: At a median follow-up of 77 months, the proportion of patients alive and disease-free was higher among the 539 women in the TAC group (87.8%) than among the 521 women in the FAC group (81.8%), representing a 32% reduction in the risk of recurrence with TAC (hazard ratio, 0.68; 95% confidence interval [CI], 0.49 to 0.93; P=0.01 by the log-rank test). This benefit was consistent, regardless of hormone-receptor status, menopausal status, or number of high-risk factors. The difference in survival rates (TAC, 95.2%; FAC, 93.5%) was not significant (hazard ratio, 0.76; 95% CI, 0.45 to 1.26); however, the number of events was small (TAC, 26; FAC, 34). Rates of grade 3 or 4 adverse events were 28.2% with TAC and 17.0% with FAC (P<0.001). Toxicity associated with TAC was diminished when primary prophylaxis with granulocyte colony-stimulating factor was provided. CONCLUSIONS: As compared with adjuvant FAC, adjuvant TAC improved the rate of disease-free survival among women with high-risk, node-negative breast cancer.

Molecular predictors of efficacy of adjuvant weekly paclitaxel in early breast cancer.

UNLABELLED: Treatment with fluororacil, epirubicin, and cyclophosphamide followed by weekly paclitaxel (FEC-P) yielded superior disease-free survival than FEC in the adjuvant breast cancer trial GEICAM 9906. We evaluate molecular subtypes predictive of prognosis and paclitaxel response in this trial. Two molecular subtype classifications based on conventional immunohistochemical and fluorescent in situ hybridization determinations were used: #1: Four groups segregated according to the combination of hormone receptor (HR) and HER2 status; #2: Intrinsic subtype classification (Triple Negative (TN), HER2, Luminal B and Luminal A). RESULTS: Both subtype classifications yielded prognostic and predictive information. HR +/HER2- patients (and Luminal A patients) had a significantly better outcome than the other subgroups of patients. The superiority of FEC-P over FEC was clearly more marked in HR-/HER2- patients (TN patients), particularly in the subset with basal phenotype (TN and either EGFR+ or cytokeratins 5/6+). The Luminal A subtype also achieved a significant benefit with FEC-P. The molecular-defined subgroup of TN was clearly predictive of better response to treatment with FEC-P. Luminal A patients had the best prognosis and also have a better outcome with weekly paclitaxel.

FOLFOX alternated with FOLFIRI as first-line chemotherapy for metastatic colorectal cancer.

BACKGROUND: 5-fluorouracil (5-FU), irinotecan, and oxaliplatin are the most active drugs in advanced colorectal cancer (CRC), and survival is improved with patient exposure to all of them. The efficacy and safety of an alternating schedule of continuous-infusion 5-FU with leucovorin (LV) plus oxaliplatin (ie, FOLFOX regimen) or irinotecan (ie, FOLFIRI regimen) was assessed in the first-line setting. PATIENTS AND METHODS: Seventy-nine patients with previously untreated, unresectable CRC were included. Treatment consisted of 5-FU/LV (de Gramont schedule) plus oxaliplatin (85 mg/m2) alternated biweekly with the same 5-FU/LV regimen plus irinotecan (180 mg/m2). Treatment was maintained until tumor progression or unacceptable toxicity was noted. RESULTS: Median age was 62 years. Performance status was 0/1 in 91% of patients, 63% had 1 organ involved, and 80% had liver metastases. A median of 6 courses per patient (range, 1-9) and a total of 952 infusions were given. The most frequent grade 3/4 toxic events were neutropenia (32%), diarrhea (26%), and asthenia (7%). Grade 1/2 neurotoxicity was seen in 59% of cases, but no grade 3/4 neurotoxicity was observed. There were no toxic deaths. An objective response rate of 54% (4 complete responses plus 39 partial responses) was attained. Median time to progression and overall survival were 13 months and 18 months, respectively. CONCLUSION: This alternating schedule is active, with efficacy results similar to those seen with sequential protocols, the advantages of less toxicity, and 100% patient exposure to irinotecan and oxaliplatin.

First-line treatment with irinotecan and raltitrexed in metastatic colorectal cancer. Mature results of a multicenter phase II study.

OBJECTIVES: The combination of irinotecan and raltitrexed is safe and active in 5-fluorouracil-refractory, metastatic colorectal cancer (CRC), with the advantage of its convenient three-weekly schedule. The aim of this multicenter phase II study was to assess its efficacy and toxicity in first-line treatment. METHODS: Between May 2000 and March 2001, 62 previously untreated patients received irinotecan (350 mg/m(2)) plus raltitrexed (3 mg/m(2)), with courses repeated every 21 days. Objective response was assessed every three courses, and treatment maintained until tumor progression or unacceptable toxicity. RESULTS: A total of 331 cycles were administered, with a median of five cycles per patient (range, 1-16). Seventeen patients achieved a partial response and 2 a complete response, for an overall intention-to-treat response rate of 30% (95% confidence interval, 18-44%). The incidence of grade 3-4 toxicity per patient was diarrhea (27%), emesis (13%), anemia (12%), neutropenia (9%), and asthenia (7%). Three patients (5%) died from treatment-related adverse events (diarrhea plus neutropenia). The median potential follow-up is now 37 months. Median survival was 12.2 months, and median time to progression was 6.3 months. CONCLUSIONS: The combination of irinotecan plus raltitrexed is an easy comfortable schedule for patients with metastatic CRC, but both efficacy and toxicity results seem suboptimal for first-line treatment.

Fibrosis cutánea de miembros inferiores inducida por paclitaxel / Paclitaxel-induced skin fibrosis of the lower limbs

El paclitaxel es un fármaco antineoplásico de la familia de los taxanos. Los principales efectos adversos más conocidos y frecuentes son la alopecia, reacciones de hipersensibilidad, neutropenia, retención de líquidos con edemas, mucositis y la eritrodisestesia. Recientemente se han descrito casos aislados de fibrosis cutánea, tanto por docetaxel como por paclitaxel, un efecto adverso raro, pero que puede ser invalidante, aunque por fortuna reversible tras la retirada del fármaco. Se describe un nuevo caso de fibrosis cutánea de miembros inferiores en una paciente en tratamiento con paclitaxel, y se revisan los casos anteriormente publicados provocados por ambos taxanos, el docetaxel y el paclitaxel (AU)

Docetaxel plus epirubicin is a highly active, well-tolerated, first-line chemotherapy for metastatic breast cancer: results of a large, multicentre phase II study.

PURPOSE: In this multicentre phase II study, the efficacy and safety profile of the combination of docetaxel and epirubicin as first-line chemotherapy for metastatic breast cancer (MBC) were evaluated. METHODS: Epirubicin (75 mg/m(2)) and docetaxel (75 mg/m(2)) were given intravenously once every 3 weeks for six cycles to 133 patients with MBC. RESULTS: The overall clinical response rate was 67% (complete and partial responses were 23% and 44%, respectively). The median time to progression was 10.8 months (95% CI 9.7-12.6) and the median overall survival was 19.5 months. Granulocyte colony-stimulating factor support was administered to 32% of patients and in 22% of cycles. Grade 3/4 neutropenia occurred in 35% of patients and febrile neutropenia in 19%. The most frequent grade 3/4 non-haematological toxicities (as percent of patients) were asthenia (6%), vomiting (5%) and nausea (5%). No patients developed congestive heart failure. CONCLUSIONS: The combination of docetaxel and epirubicin was highly active as first-line treatment for MBC and showed a manageable toxicity profile.

Multicenter phase I study of irinotecan plus raltitrexed in patients with 5-fluorouracil-refractory advanced colorectal cancer.

Irinotecan and raltitrexed are active against advanced colorectal cancer, act through different mechanisms, and have non-overlapping toxicity profiles. In vitro studies have shown a schedule-dependent synergism between both drugs. The aim of this multicenter study was to determine the maximum tolerated dose (MTD) of this combination. Patients with 5-fluorouracil-refractory, advanced colorectal cancer were eligible. Dose escalation consisted of irinotecan (250-350 mg/m(2) as a 60-min infusion) in combination with a fixed dose of raltitrexed (3 mg/m(2) as a 15-min infusion, 1 h after irinotecan). Courses were repeated every 21 days. Three to 6 patients were to be included at each dose level. Dose limiting (NCI-CTC grade 3-4) toxicities (DLT) were assessed during the first 2 cycles. Thirteen patients were recruited (4, 3 and 6 in levels I, II and III, respectively). Main toxicity was diarrhea and asthenia, whereas myelotoxicity was mild. At level III, 2/6 patients experienced DLT (grade 4 diarrhea and neutropenia). The MTD was not reached, but further dose escalation was not attempted. Among 12 patients with measurable disease, 2 partial responses were observed for an overall response rate of 17%. The combination of single-agent full doses of irinotecan (350 mg/m(2)) and raltitrexed (3 mg/m(2)) in a 3-weekly schedule is feasible, with mild toxicity and a promising clinical activity. Diarrhea is the DLT, but it is not more common or severe than that described with irinotecan alone.
