Background: Patients with newly diagnosed high-risk Burkitt lymphoma are treated with high-intensity immune-chemotherapy regimens such as R-CODOX-M/R-IVAC or with lower-intensity regimens such as DA-EPOCH-R. The aim of this study was to make a formal comparison between these regimens.

Methods: This multicentre, phase 3, open-label, randomised study was done in 26 clinical centres in the Netherlands, Belgium, and Switzerland.

Advanced triple negative breast cancer (TNBC) is an aggressive, but initially chemo-sensitive disease. The prognosis is poor and more than three quarters of patients experience progression 12 months after the initiation of conventional first-line chemotherapy. Approximately two thirds of TNBC express epidermal growth factor receptor 1 (EGFR).

Introduction: Standard-dose eribulin mesylate (1.4 mg/m d1 + 8) achieves clinical benefit rates of 26%-52% in patients with metastatic breast cancer (mBC). <10% of patients in the registration trial were ≥ 70 years old; dose reductions were common in these older patients.

Purpose: These are the final results of a national registry on cancer patients with COVID-19 in Switzerland. Methods: We collected data on symptomatic COVID-19-infected cancer patients from 23 Swiss sites over a one-year period starting on 1 March 2020. The main objective was to assess the outcome (i.

Background: Bone-targeted agents (BTAs) are widely used in the management of patients with bone metastases from solid tumors. Knowledge of the impact of their routine care use on patient-reported pain and bone pain-related quality of life (QoL) is limited.

Methods: This real world, cross-sectional study enrolled patients over a 3-month period through oncologists across Switzerland.

Article Synopsis
  • * Involving 86 oncologists and 417 patients, most doctors adhered to guidelines, with denosumab being the preferred BTA, administered primarily every 3-4 weeks.
  • * Results showed effective pain management, high guideline compliance, and a low occurrence of skeletal complications, indicating positive outcomes from BTA usage in routine care.

Daratumumab, an anti-CD38 antibody, is effective in AL amyloidosis with low tumor burden. Data of daratumumab treatment in patients with AL amyloidosis but high tumor burden (≥10% bone marrow plasma cells) are limited. We report retrospective data of 10 consecutive patients with high tumor burden treated with daratumumab for relapsed/refractory AL amyloidosis.

We report on a 73-year-old male patient with recurrent thrombosis of his infrarenal aortic prosthesis. Histologically, the thrombus contained cells of an ALK-negative anaplastic large cell T cell lymphoma (ALCL). Imaging studies were negative for other lymphoma manifestations; however, 3 months before, the patient had developed skin lesions consistent with lymphomatoid papulosis type A (LypA) which were clonally related to the ALCL.

Objective: Primary gall bladder melanoma is a rare and controversial entity. So far, only 36 cases are documented in the literature. Metastatic melanoma targeting the gall bladder, however, has been reported to occur in about 15-20% of melanoma patients and is much more common.

Background: The aim was to evaluate quality of life (QoL), pain, and fatigue in patients with metastatic castration-resistant prostate cancer (mCRPC) treated with different regimens after first-line docetaxel, as well as disease progression.

Patients And Methods: Patients with mCRPC having received first-line chemotherapy with docetaxel were eligible. Second-line treatment choice was at the discretion of the local investigator.

An increasing number of older patients are suffering from aggressive lymphoma. Effective and more tolerable treatment regimens are urgently needed for this growing patient population. Patients with aggressive lymphoma not eligible for anthracycline-based first-line therapy or intensive salvage regimens were treated with the rituximab-bendamustine-lenalidomide (R-BL) regimen (rituximab 375 mg/m(2)  day 1, bendamustine 70 mg/m(2)  d 1, 2, lenalidomide 10 mg d 1-21) for six cycles every 4 weeks.

Background: Postoperative hemithoracic radiotherapy has been used to treat malignant pleural mesothelioma, but it has not been assessed in a randomised trial. We assessed high-dose hemithoracic radiotherapy after neoadjuvant chemotherapy and extrapleural pneumonectomy in patients with malignant pleural mesothelioma.

Methods: We did this phase 2 trial in two parts at 14 hospitals in Switzerland, Belgium, and Germany.

Purpose: Patients with brain metastases (BM) rarely survive longer than 6months and are commonly excluded from clinical trials. We explored two combined modality regimens with novel agents with single agent activity and radiosensitizing properties.

Patients And Methods: In this randomised phase II trial patients with BM from NSCLC were randomly assigned to 30Gy WBRT with either concomitant gefitinib (GFT) 250mg/day continuously or temozolomide (TMZ) 75mg/m(2) for 21/28days.

Background: In an earlier study, intravenous (i.v.) ibandronate 6 mg administered every 3-4 weeks had a similarly good renal safety profile whether infused over 15 or 60 min in women with breast cancer and bone metastases.

Background: Only responding patients benefit from preoperative therapy for locally advanced esophageal carcinoma. Early detection of non-responders may avoid futile treatment and delayed surgery.

Patients And Methods: In a multi-center phase ll trial, patients with resectable, locally advanced esophageal carcinoma were treated with 2 cycles of induction chemotherapy followed by chemoradiotherapy (CRT) and surgery.

Purpose: To evaluate the effects of palliative chemotherapy with gemcitabine plus capecitabine (GemCap) on patient-reported outcomes measured using clinical benefit response (CBR) and quality-of-life (QOL) measures in patients with advanced biliary tract cancer.

Patients And Methods: Patients had to manifest symptoms of advanced biliary tract cancer and have at least one of the following: impaired Karnofsky performance score (60 to 80), average analgesic consumption >or= 10 mg of morphine equivalents per day, and average pain intensity score of >or= 20 mm out of 100 mm. Treatment consisted of oral capecitabine 650 mg/m(2) twice daily on days 1 through 14 plus gemcitabine 1,000 mg/m(2) as a 30-minute infusion on days 1 and 8 every 3 weeks until progression.

B-cell lymphomas express tumor-specific immunoglobulin, the variable regions of which [idiotype (Id)] can serve as a target for active immunotherapy. Promising results have been obtained in clinical studies of Id vaccination using Id proteins.However, Id protein is laborious and time-consuming to produce.

Tumor-specific clonal immunoglobulin expressed by B-cell lymphomas (idiotype [Id]) can serve as a target for active immunotherapy. We have previously described the vaccination of 4 patients with follicular lymphoma using dendritic cells (DCs) pulsed with tumor-derived Id protein and now report on 35 patients treated using this approach. Among 10 initial patients with measurable lymphoma, 8 mounted T-cell proliferative anti-Id responses, and 4 had clinical responses--2 complete responses (CRs) (progression-free [PF] for 44 and 57 months after vaccination), 1 partial response (PR) (PF for 12 months), and 1 molecular response (PF for 75+ months).
