SEOM clinical guidelines for the treatment of Hodgkin’s lymphoma

Hodgkin lymphoma (HL) is an uncommon B cell lymphoid malignancy representing approximately 10-15 % of all lymphomas. HL is composed of two distinct disease entities; the more commonly diagnosed classical HL and the rare nodular lymphocyte-predominant HL. An accurate assessment of the stage of disease and prognostic factors that identify patients at low or high risk for recurrence are used to optimize therapy. Patients with early stage disease are treated with combined modality strategies using abbreviated courses of combination chemotherapy followed by involved-field radiation therapy, while those with advanced stage disease receive a longer course of chemotherapy often without radiation therapy. High-dose chemotherapy (HDCT) followed by an autologous stem cell transplant (ASCT) is the standard of care for most patients who relapse following initial therapy. Brentuximab vedotin should be considered for patients who fail HDCT with ASCT (AU)

SEOM clinical guidelines for the treatment of follicular non-Hodgkin’s lymphoma

Follicular non-Hodgkin's lymphoma (FL) is a nodal B lymphoid malignancy that originates from the germinal center of a lymph node. FL is the second most frequent lymphoma subtype. The course of the disease is usually characterised by a typically indolent clinical course, with a median survival rate of 8-10 years, although most patients relapse after treatment. Diagnosis should always be based on a surgical specimen like an excisional node lymph biopsy. The first-line treatment of FL will depend of extension disease, tumour burden, patient symptoms, performance status and also patient decision. The addition of rituximab to conventional chemotherapy has improved ORR, PFS and OS. As first line in patients that need treatment, a combination of chemotherapy with rituximab induction followed by 2 years of rituximab maintenance is the best option. High-dose chemotherapy with autologous stem-cell transplantation in first line has not shown improvement and is not recommended as first-line therapy. Before any treatment decision in relapsed patients, a repeat biopsy is mandatory to rule out a transformation into large cell aggressive lymphoma. Standard treatment is controversial, depends on the efficacy of prior treatment, duration of the time-to-relapse, patient’s age and histological findings at relapse (AU)

Prevalence of EGFR mutations in newly diagnosed locally advanced or metastatic non-small cell lung cancer Spanish patients and its association with histological subtypes and clinical features: The Spanish REASON study.

BACKGROUND AND OBJECTIVES: The aim of the REASON study is to determine the frequency of EGFR mutation in advanced non-small cell lung cancer (aNSCLC) patients in Spain (all histologies), and to better understand the clinical factors (gender, smoking habits and histological subtypes) that may be associated with EGFR mutations, in an unselected sample of aNSCLC patients. METHODS: All newly diagnosed aNSCLC patients from 40 selected centers in Spain were prospectively included for a 6-month period. Patient characteristics were obtained from clinical records. Mutation testing was performed on available tumor samples. Exploratory analyses were performed to characterize the clinico-pathological factors associated with presence of EGFR mutations. RESULTS: From March 2010 to March 2011, 1113 patients were included in the study, of which 1009 patients provided sample for EGFR mutation analysis (90.7%). Mutation analysis was not feasible in 146/1113 patients (13.1%) due to either sample unavailability (79/1113; 7.1%) or sample inadequacy (67/1113; 6.0%). Twenty-five out of 1113 patients (2.3%) were excluded due to unavailable information. Most patients (99.5%) were Caucasian, 74.5% were male, and predominantly were current (38.1%) or former smokers (44.0%). Median age was 66 years (range 25-90) and 70.7% of patients had non-squamous histology (57.8% adenocarcinoma, 1.8% bronchoalveolar, 11.1% large-cell carcinoma). Exon 19 deletions and the exon 21 L858R point mutation were analyzed in 942/1009 (93.4%) samples. Mutation rate was 11.6% (82.6% exon 19 dels and 17.4% L858R). To be never smoker (38.1%), female (25.4%), with bronchioloalveolar carcinoma (22.2%) or adenocarcinoma (15.4%) histology was associated with a higher prevalence of EGFR mutations. Exons 18, 20 and 21 (excluding L858R) were analyzed in 505/942 samples, and EGFR mutations were found in 22/505 samples (4.4%). CONCLUSION: The estimated prevalence of sensitizing EGFR mutations (exon 19 del, exon 21 L858R) in an unselected samples of newly diagnosed aNSCLC patients in Spain (all histologies) is consistent with previous published data in Caucasian patients. When a sample is available, EGFR mutation testing is feasible in over 90% of cases, and may therefore be suitable for routine clinical practice. CLINICALTRIALS. GOV IDENTIFIER: NCT01081496.

Infiltrating ductal carcinoma and synchronous malignant phyllodes tumour. Diagnostic and therapeutic approaches

Simultaneous presentation of breast cancer and malignant phyllodes tumour is rare. A female patient presented with a nodule in her left breast (infiltrating ductal carcinoma). On magnetic nuclear resonance another suspicious lesion (malignant phyllodes) was found in the right breast. Bilateral mastectomy was performed. Thirty two months later the patient is still free of disease. The approach to dealing with synchronous breast tumours should be the same as that normally used (AU)

A patient with breast cancer with hepatic metastases and a complete response to herceptin as monotherapy

The majority of deaths due to breast cancer occur in the context of complications secondary to metastatic disease. Trastuzumab, as a second line treatment, has shown a 15% objective response rate in patients with metastatic breast cancer. We present the case of a patient with two breast tumours, the second of more aggressive characteristics, with negative hormone receptors and c-erb-B2 +++, and with few therapeutic options due to her hepatic insufficiency secondary to metastatic disease; she was administered herceptin as monotherapy, and she had a complete clinical response. Trastuzumab has revolutionised the management of patients with metastatic breast cancer and Her-2- neu overexpression. Its combination with chemotherapy agents achieves a synergic activity (AU)
