Daratumumab for relapsed or refractory AL amyloidosis with high plasma cell burden.

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. The median age at diagnosis was 62.3 years; all patients had cardiac involvement, and six (60%) patients had renal involvement. Median bone marrow plasma cell infiltration was 15% (range 10%-40%), and the median difference between involved and noninvolved free light-chains (dFLC) was 446 mg/L (range 102-1392 mg/L). Patients had a median of three prior lines of therapy, including bortezomib in all patients and lenalidomide in seven (70%) patients. The median time to first hematological response was 14 days (range 7-28 days), and the median time to best hematological response was 64 days (range 7-301 days). The hematological overall response was 90%, with high-quality response (≥ very good partial remission [VGPR]) in 70% of the patients. Fifty percent of the patients had a cardiac response after a median of 3.8 months (range 0.7-9.1). Infusion-related adverse events ≤ grade 2 occurred in seven (70%) patients and grade 3 adverse events in one patient. After a median follow-up time of 10 months, eight (80%) patients continued to receive daratumumab. We conclude that daratumumab is a very effective and safe treatment option in AL patients with relapsed/refractory disease and high disease burden at diagnosis. Daratumumab leads to rapid disease control and improvement of organ function.

Bendamustine, lenalidomide and dexamethasone (BRd) has high activity as 2nd -line therapy for relapsed and refractory multiple myeloma - a phase II trial.

The combination of lenalidomide (Revlimid® , R) and dexamethasone (d) is a standard regimen for patients with relapsed/refractory multiple myeloma (rrMM). With this regimen, only a small fraction of patients will achieve high quality responses [≥ very good partial response (VGPR)]. The combination of bendamustine (B), lenalidomide and dexamethasone (BRd) has shown high efficacy in patients with advanced rrMM. However, dose-limiting haematotoxicity restricted its use in extensively pre-treated patient populations. This prospective, multicentre Phase II study evaluated the efficacy and safety of BRd in rrMM patients with one prior line of therapy. Fifty patients were enrolled (median age 68·5 years [range 46-83]) and were treated with B 75 mg/m2  days 1, 2; R 25 mg days 1-21 and d (40/20 mg) days 1, 8, 15 and 22, for 6 28-day induction cycles, followed by 12 cycles with Rd alone. Pegfilgrastim was administered according to protocol-defined criteria. The study aimed to demonstrate a complete response (CR)/VGPR rate of >40% after induction therapy. Of 45 evaluable patients, 23 (51%) achieved a CR/VGPR. Grade 4 neutropenia or thrombocytopenia occurred in 17 (34%) and 8 (16%) of patients, respectively. BRd is a safe and efficacious regimen as a second line treatment for rrMM, leading to high quality responses in a considerable proportion of patients.

Real-World Evaluation of Quality of Life, Effectiveness, and Safety of Aflibercept Plus FOLFIRI in Patients with Metastatic Colorectal Cancer: The Prospective QoLiTrap Study.

Aflibercept plus FOLFIRI prolongs overall survival (OS) in patients with metastatic colorectal cancer after the failure of oxaliplatin-containing therapy. QoLiTrap prospectively evaluated the quality of life (QoL) and effectiveness of this regimen in daily clinical practice, according to RAS status, sex, and prior targeted therapy, especially epidermal growth factor receptor inhibitors (EGFR-I). The primary endpoint was the percentage of patients whose EORTC QLQ-C30 global health status (GHS) improved or reduced by <5% from baseline during the first 12 weeks of therapy. Secondary endpoints included objective response rate (ORR), progression-free survival (PFS), overall survival (OS), and safety. One thousand two hundred and seventy-seven patients were treated with aflibercept plus FOLFIRI and 872 were evaluable for QoL. GHS improved or decreased by <5% in 40.3% of cases. The ORR was 20.8%, the median PFS was 7.8 months (95% confidence interval (CI), 7.3−8.3), and the median OS was 14.4 months (95% CI, 13.1−18.1). After prior EGFR-I, the ORR was 23.7%, median PFS was 9.4 months (95% CI, 6.5−12.9), and median OS was 17.4 months (95% CI, 10.5−33.7). The safety profile was consistent with previously reported data. Aflibercept plus FOLFIRI given in daily practice maintained QoL in mCRC patients, was associated with a high objective tumor response, and retained its activity regardless of sex, RAS status, and prior EGFR-I therapy.

Self-reported compliance with capecitabine: findings from a prospective cohort analysis.

OBJECTIVES: While oral anticancer treatment has increased the convenience for patients with no risk of venous access complications compared to intravenous drug administration, a high level of compliance cannot always be assumed. The aim of the present report was to evaluate real-life drug adherence in a prospective cohort analysis of patients with gastrointestinal or breast cancer treated with capecitabine-based chemotherapy. METHODS: Twenty-nine Swiss oncologists recruited patients receiving capecitabine, either as monotherapy or in combination with other chemotherapeutic agents, in a prospective fashion. Patients recorded both their capecitabine intake and any adverse effects each day in patient diaries. RESULTS: A total of 177 patients were included, 143 (81%) with gastrointestinal tumours and 34 (19%) with breast cancer. Overall, 161 patients (91%) were considered as fully compliant, while 16 patients (9%) reported some kind of compliance error. Reasons for non-compliance included forgetting to take treatment (n = 9), side effects (n = 4) and misunderstanding instructions (n = 3). Self-reported compliance was not influenced by age or Eastern Cooperative Oncology Group performance status, but there was a trend towards better compliance with capecitabine therapy if fewer adverse effects occurred (p = 0.07, simple logistic regression). CONCLUSIONS: Self-reported compliance with capecitabine-based therapy in clinical practice is high and seems to be adversely affected by side effects.

Long-Lasting Complete Remission of Small-Cell Carcinoma of the Pancreas with Carboplatin and Etoposide Complicated by Gallbladder Adenocarcinoma Diagnosed during Follow-Up.

Small-cell carcinoma of the pancreas (PSCC) is a highly aggressive neoplasia with a dismal prognosis. It is extremely rare, with only a few cases reported in the literature. There is a paucity of clinical data to guide management and since the disease is mainly diagnosed at an advanced stage standard treatment consists of chemotherapy based upon treatment protocols used for small-cell lung cancer. We report the case of a female diagnosed with PSCC who achieved complete clinical remission after treatment with carboplatin and etoposide. During a 3-year follow-up the patient developed a gallbladder adenocarcinoma that was treated by surgical resection but relapsed within 20 months with widespread hematogenous metastasis.

Advanced Gastric Cancer: Current Treatment Landscape and a Future Outlook for Sequential and Personalized Guide: Swiss Expert Statement Article.

BACKGROUND: Gastric cancer is a leading cause of cancer-related deaths worldwide. Several treatment possibilities have been investigated, but only a few show clinically meaningful results. SUMMARY: Systemic treatment options for advanced gastric cancer (aGC) have evolved over the recent years, implementing the growing molecular knowledge of this heterogeneous disease. Molecular profiling (at least for HER-2-expression, microsatellite instability status, Epstein-Barr virus expression, and programmed death ligand-1 expression/combined positive score [CPS]) is recommended for all therapy-fit patients prior to the start of a systemic treatment and is crucial for decisions on treatment strategy and drug selection. Various examples like the application of trastuzumab in the HER-2-positive subgroup underline the benefits of this approach starting from the first-line setting. A combination of platinum and fluoropyrimidine remains the first-line chemotherapy backbone in the treatment of advanced gastric cancer. Triplet combinations adding taxanes to the doublet regimen are reserved for certain scenarios. Unfortunately, almost all patients who receive first-line treatment (with or without anti-HER-2 blockade) progress and <70% are eligible for a second-line therapy. The addition of monoclonal antibodies has substantially improved outcomes in this setting. As such, ramucirumab has led to significant and clinically meaningful advancements in the second-line treatment. Furthermore, immuno-oncology with checkpoint inhibition and immune stimulation has evolved in the field of aGC. Recent first-line data show a significant survival benefit in aGC patients with a CPS ≥ 5 under immunochemotherapy. Nonetheless, the impact of immunotherapy combinations and immunochemotherapy remains an area of investigation. Key Message: In this review, we highlight recent improvements in the treatment landscape of advanced gastric cancer, the heterogeneity of this disease, and possible personalized targets.

Intense therapy in patients with locally advanced esophageal cancer beyond hope for surgical cure: a prospective, multicenter phase II trial of the Swiss Group for Clinical Cancer Research (SAKK 76/02).

BACKGROUND: There is no standard treatment for patients with locally advanced esophageal carcinoma without systemic metastasis in whom surgery is no longer considered a reasonable option. PATIENTS AND METHODS: Patients with cervical esophageal tumors, locally very advanced stage (T4 and/or M1a) or locally advanced (T3 and/or N+) with comorbidities were included. THERAPY: 2 cycles of induction chemotherapy (cisplatin and docetaxel, both 75 mg/m(2) 3-weekly) followed by chemoradiation therapy (CRT) comprising a total radiation dose of 59.4 Gy together with docetaxel 15 mg/m(2) and cisplatin 25 mg/m(2) (5 weekly doses). Primary endpoint: Histologically proven freedom from local failure 6 months after CRT completion. RESULTS: 21 patients were included: 12 had locally very advanced tumors, 3 had cervical esophagus tumors, and 6 were medically unfit for surgery. 18 patients completed therapy per protocol. Grade 3/4 toxicities during CRT were thrombopenia (10%) and dysphagia (15%). 1 patient died due to herpes simplex infection. The primary endpoint was achieved by 4 patients, 6 were alive after median follow-up of 34 months, and median survival was 16 months. Most patients experienced lasting improvement of dysphagia following induction chemotherapy. CONCLUSIONS: This regimen is feasible, showed clinically meaningful, long-lasting improvements in quality of life and resulted in long-term survival in 29% of the patients.

Prospective, observational practice survey of applied skin care and management of cetuximab-related skin reactions: PROSKIN study.

PURPOSE: The study aimed to investigate strategies to prevent and treat cetuximab-induced skin reactions and their perceived effectiveness in patients with metastatic colorectal cancer (mCRC) and recurrent/metastatic squamous cell cancer of the head and neck (SCCHN). METHODS: This open-label, prospective observational study was conducted in Switzerland. RESULTS: A total of 125 patients were included (n = 91 mCRC, n = 34 SCCHN; mean age 63.3 years; 73.6% males). The frequency of acneiform rash grade ≥ 2 increased from 12.6% at week 2 to 21.7% at week 16. The proportion of patients who reported no skin reaction decreased from 75.6% at week 2 to 43.3% at week 16. The most frequently used skin products at any time of observation were moisturizing (77.6%), lipid-regenerating (56.8%) or urea-containing products (52%), systemic antibiotics (49.6%), and vitamin K1 cream (43.2%). There was no clear effectiveness pattern for all product classes: in given patients, either the product showed no effect at all or a moderate/strong effect, consistently over time. CONCLUSIONS: A great variety of low-cost general skin care products were commonly used. According to physician's preference, systemic antibiotics and vitamin K1 cream are an appropriate approach to prevent or treat cetuximab-related skin toxicity.

Diagnosis and treatment of diffuse large B-cell lymphoma.

Diffuse large B-cell lymphoma (DLBCL) is the most frequently-occurring type of malignant lymphoma in the Western world. It has an aggressive natural history, with a median survival of less than one year if left untreated. Immunochemotherapy regimens, consisting of the anti-CD20 antibody rituximab typically in combination with cyclophosphamide, doxorubicin, vincristine and prednisone (CHOP), are currently the treatment backbone. Despite remarkable progress in improving patient survival, clinical outcomes are still unsatisfactory for certain subsets of patients, including the elderly and very elderly and those with highly aggressive disease. This review outlines some of the current treatment strategies for DLBCL and discusses the main issues that affect clinical practice.

Diagnosis and treatment of follicular lymphoma.

Follicular lymphoma is a slow-growing disease exhibiting a heterogeneous clinical course, with a subset of patients experiencing a rapid disease course in the first two years and some developing disease transformation to a more aggressive phenotype. The advent of highly effective therapies has resulted in an increasing number of patients who achieve long-term progression-free survival alongside a good quality of life. Monoclonal antibodies, such as rituximab, either alone or in combination with chemotherapy regimens or radioimmunotherapy have been used with significant improvements in outcome. New treatment strategies such as new antibodies, biologic agents or vaccination therapy are also under investigation for the treatment of relapsed or refractory disease, further expanding the available options for patients and physicians alike. This article presents an overview of the current therapeutic strategies for the management of follicular lymphoma, focusing on the issues encountered in clinical practice.
