Quality of life, effectiveness, and safety of aflibercept plus FOLFIRI in older patients with metastatic colorectal cancer: An analysis of the prospective QoLiTrap study.

INTRODUCTION: Colorectal cancer (CRC) mainly affects older patients. The pivotal VELOUR phase III trial of aflibercept plus FOLFIRI in metastatic CRC (mCRC) included only 5.9% of patients aged ≥75 years. Herein, we report a preplanned analysis from QoLiTrap, a large prospective observational study evaluating the impact of age on quality of life (QoL), effectiveness, and safety of aflibercept plus FOLFIRI in daily clinical practice in Europe. MATERIALS AND METHODS: Enrolled patients had progressive mCRC, had failed a prior oxaliplatin-based regimen, and had received aflibercept (4 mg/kg) plus FOLFIRI every two weeks until disease progression, death, unacceptable toxicity, or physician/patient decision. Analyses were performed by age classes (<60, 60-64, 65-69, 70-74, and ≥ 75 years). The primary endpoint was the percentage of patients whose global health status (GHS) of the European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30) was maintained (i.e., no worsening from baseline by at least 5% over a 12-week treatment). Secondary endpoints included tumor objective response rate (ORR), progression-free survival (PFS), overall survival (OS), and safety. RESULTS: Overall, 1277 patients (<60 years, n = 327; 60-64 years, n = 231; 65-69 years, n = 227; 70-74 years, n = 259; and ≥ 75 years, n = 233) were treated, of whom 872 were evaluable for QoL. GHS was maintained in 36.5%, 41.6%, 38.9%, 41.8%, and 44.8% of patients aged <60, 60-64, 65-69, 70-74, and ≥ 75 years, respectively. Age did not influence PFS (median 7.8 months), OS (median 14.4 months), or ORR (20.8%). Number of cycles, dose delays for any cause, and dose reductions for adverse events (AEs) were comparable between age classes. Grade ≥ 3 AEs occurred in 47.7%, 51.9%, 51.5%, 55.2%, and 55.8% of patients aged <60, 60-64, 65-69, 70-74, and ≥ 75 years, respectively. The main grade ≥ 3 AEs were hypertension (11.2%) and diarrhea (9%) in patients aged ≥75 years. DISCUSSION: The results suggest that aflibercept plus FOLFIRI maintains QoL and retains its activity, including a high objective tumor response, regardless of age and treatment line. In fit older patients, the safety profile seems manageable, with no new safety signals.

Treatment Algorithm for Patients With Gastric Adenocarcinoma: Austrian Consensus on Systemic Therapy - An Update.

Over the last decade, therapeutic options for patients with gastric cancer have improved significantly. However, despite these recent advances, mortality is still substantial. Surgery and chemotherapy represent the cornerstones of patient management. Immune checkpoint inhibitors as well as targeted treatments such as HER2-directed therapies and antiangiogenic agents contribute to improved patient prognosis. Herein, we present the updated version of an Austrian consensus on the systemic treatment of patients with gastric adenocarcinoma and adenocarcinoma of the lower gastroesophageal junction, including those with human epidermal growth receptor 2 (HER2) overexpression, microsatellite instability, programmed death-ligand 1 (PD-L1)-positive disease, and claudin 18.2 positivity. The consensus considers the curative setting as well as first-line and later-line systemic treatment options in advanced disease. For HER2-positive disease, HER2 testing is discussed in addition to a review of first-line and later-line therapies. Potential future therapies are also listed, with a focus on targeted [e.g., fibroblast growth factor receptor 2 (FGRF2)-directed] treatments that might provide a further step forward in the management of patients with gastric cancer.

Austrian treatment algorithms in HER2-positive metastatic breast cancer: a 2022 update.

In the past 12 months a plethora of relevant novel data for the treatment of metastatic HER2 positive breast cancer were published. To bring this new evidence into a clinical perspective, a group of Austrian breast cancer specialists updated their previously published treatment algorithm for those patients. For this consensus paper a total of eight scenarios were developed in which treatment strategies appropriate for specific patient profiles were evaluated. Consensus was established by detailed discussions of each scenario and by reaching full consensus.

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.

REGO-ACT: assessment of physical activity during treatment with regorafenib for metastatic colorectal cancer.

BACKGROUND: A frequent side effect of the multikinase inhibitor regorafenib is fatigue. Physical activity has shown potential in reducing cancer-related fatigue. METHODS: This non-interventional pilot study assessed physical activity levels of metastatic colorectal cancer (mCRC) patients treated with regorafenib based on median daily step counts measured at 1­week intervals using a pedometer. The study further evaluated relations between physical activity levels and fatigue, quality of life (QoL) and progression-free survival. RESULTS: Pedometer data were available for 22 out of 25 enrolled patients. The numbers of days with available pedometer data ranged from 6 to 100 days. The overall median daily step count was 2357 (range 10-14,931), with substantial interindividual and intraindividual variations. Interindividual median weekly step counts were in the range of 5000-7000 in some, 2000-3000 in others, and several hundreds or less in a few patients. Intraindividual daily step counts also varied by several thousands of steps. Step counts in weeks in which patients reported fatigue were well within the range of or even higher than step counts in adjacent weeks, indicating a lack of correlation. The risk of disease progression was also independent of median weekly step counts; however, significant correlations were seen between QoL and step counts. CONCLUSION: Despite the severity of their disease patients showed remarkable levels of walking activity. In view of the highly individual activity levels, exercise prescriptions for seriously ill patient populations should be personalized to the specific needs and preferences of each individual patient.

Patterns of care in metastatic pancreatic cancer: patient selection in clinical routine.

BACKGROUND: The management of patients with metastatic pancreatic cancer (mPC) is challenging, and the optimal treatment strategy is debated among experts. In an attempt to identify treatment decision criteria and to investigate variations in the first-line management of this disease, we performed an analysis of treatment algorithms among experts in the field of pancreatic cancer. The aim of this study was to identify relevant criteria in the complex process of patient selection and decision making for the management of mPC patients. METHODS: Experts from the ABCSG (Austrian Breast and Colorectal Cancer Study Group) Pancreatic Cancer Club were contacted and agreed to participate in this analysis. Eight experts from seven centers in Austria provided their decision algorithms for the first-line treatment of patients with mPC. Their responses were converted into decision trees based on the objective consensus methodology. The decision trees were used to identify consensus and discrepancies. RESULTS: The final treatment algorithms included four decision criteria (performance status, age, comorbidities, and symptomatic disease) and six treatment options: mFOLFIRINOX, gemcitabine + nab-paclitaxel, gemcitabine mono, 5-FU mono, gemcitabine/erlotinib, and best supportive care (BSC). CONCLUSIONS: We identified consensus for the treatment of young and fit patients with mFOLFIRINOX. With higher age and reduced performance status, gemcitabine + nab-paclitaxel was increasingly used. For patients with Eastern Co-operative Oncology Group Performance Status (ECOG PS) 4, BSC was the treatment of choice. Among experts, different decision criteria and treatment options are implemented in clinical routine. Despite multiple options in current recommendations, a consensus for specific recommendations was identified.

Neoadjuvant Chemotherapy with Gemcitabine plus Cisplatin in Patients with Locally Advanced Bladder Cancer.

BACKGROUND: Neoadjuvant chemotherapy with methotrexate-vinblastine-doxorubicin-cisplatin (MVAC) is the standard of care for muscle-invasive urothelial bladder cancer. Gemcitabine plus cisplatin (GC) shows similar efficacy with less toxicity in the metastatic setting and has therefore often been used interchangeably with MVAC. We report on the efficacy and safety of neoadjuvant GC in patients with locally advanced urothelial cancer. MATERIALS AND METHODS: We prospectively evaluated 87 patients in 2 centers. Their median age was 68 years. Treatment consisted of 3× GC prior to radical cystectomy. The primary endpoint was pathologic response. The secondary endpoints were safety, progression-free survival (PFS), and overall survival (OS). RESULTS: In all, 83 patients finished chemotherapy; 80 patients were evaluable for the primary endpoint. Pathologic complete response (pCR) was achieved in 22.5% and near pCR was seen in 33.7% of the patients. The 1-year PFS rate was 79.5% among those patients achieving ≤pT2 versus 100% among those patients achieving pCR or near pCR (p = 0.041). Five-year OS was 61.8% (95% CI 67.6 to NA). GC was well tolerated. Grade 3/4 toxicities occurred in 38% of the patients. There was no grade 3/4 renal toxicity, febrile neutropenia, or death. CONCLUSION: Neoadjuvant GC is a well-tolerated regimen. Although the pathologic response is lower than that reported with MVAC, our data support GC as a feasible option in the absence of a prospective randomized comparison, particularly for older patients, since its toxicity is lower than that of MVAC.

Advanced-stage hepatocellular carcinoma: transarterial chemoembolization versus sorafenib.

PURPOSE: To compare the efficacies of transarterial chemoembolization (TACE) and sorafenib in patients with advanced-stage hepatocellular carcinoma (HCC). MATERIALS AND METHODS: The retrospective analysis of the data was approved by the institutional review board; the requirement to obtain informed consent was waived. Three hundred seventy-two patients with HCC were treated between January 1999 and December 2009. Patients with advanced HCC according to the Barcelona Clinic Liver Cancer (BCLC) staging classification (Child-Pugh class A or B, Eastern Cooperative Oncology Group performance status of 1-2, and/or macrovascular invasion or extrahepatic metastasis) were included in the study (n = 97). Thirty-four patients underwent conventional TACE with doxorubicin plus lipiodol or TACE with drug-eluting beads; 63 patients were treated with sorafenib. RESULTS: The median duration of sorafenib treatment was 4.6 months (95% confidence interval [CI]: 3.2, 6.0 months). The median number of TACE sessions per patient was 3 ± 2. Side effects of TACE and sorafenib were comparable to those reported in the literature. The median time to progression was similar between the two treatment groups (P = .737). The median overall survival was 9.2 months (95% CI: 6.1, 12.3 months) for patients treated with TACE and 7.4 months (95% CI: 5.6, 9.2 months) for those treated with sorafenib (P = .377). Only Child-Pugh class was associated with a better overall survival at uni- and multivariate analysis. CONCLUSION: TACE achieved a promising outcome in select patients with advanced HCC (BCLC stage C).

Oxaliplatin, irinotecan and cetuximab in advanced gastric cancer. A multicenter phase II trial (Gastric-2) of the Arbeitsgemeinschaft Medikamentose Tumortherapie (AGMT).

BACKGROUND: Patients suffering from advanced gastric cancer still have a poor prognosis and treatment options are limited. In our previous phase II trial (AGMT-Gastric-1), we showed that the combination of oxaliplatin and irinotecan was well tolerated and effective. The same chemotherapy regimen was now tested in combination with cetuximab in a multicenter phase II trial. PATIENTS AND METHODS: Oxaliplatin at 85 mg/m(2) biweekly and irinotecan at 125 mg/m(2) biweekly were combined with cetuximab at 400 mg/m(2) loading dose and subsequent weekly infusions of 250 mg/m(2). Fifty-one patients with histologically proven unresectable and/or metastatic gastric adenocarcinoma were treated in the first line setting. The median age was 62 years. A single metastatic site was found in 24 patients, 27 patients had multiple metastatic sites. RESULTS: Frequently reported adverse events (in more than 20% of patients) were predominantly grade 1 or 2 and included neutropenia (35%), thrombocytopenia (33%), anemia (73%), nausea (45%), diarrhea (57%), alopecia (22%), and fatigue (37%). Grade 3/4 toxicities included neutropenia in 9/1 patients., thrombocytopenia in 1/0 patients, anemia in 3/1 patients, nausea in 2/0 patients, and diarrhea in 7/2 patients. Sensory neuropathy occurred mostly as grade 1 and 2 in 37% of patients, grade 3 neurotoxicity was observed in 7 patients. Acne-like rash grades 1/2/3/4 were reported in 31%/20%/6%/2% of patients respectively. Thirteen patients discontinued the study due to neutropenia (n=5), nausea/vomiting (n=1), diarrhea (n=1), toxic colon (n=2), and allergic reaction to cetuximab at first (n=2), second (n=1) or third infusion (n=1). Thirty-five patients were assessable for response, with 1 patient (3%) showing a complete response, 21 patients (60%) a partial response, 7 patients (20%) a stable disease, and 6 patients (17%) a progressive disease respectively. The median time to progression was 24.8 weeks, median overall survival was 38.1 weeks. All patients tested had a wild type KRAS status. CONCLUSION: The combination of oxaliplatin and irinotecan with cetuximab is safe and its action established in advanced gastric cancer.

[Systemic treatment of renal cell carcinoma - recent update]. / Systemische Therapie des Nierenzellkarzinoms - aktuelle Behandlungsmöglichkeiten.

Renal cell cancer is the most common form of all malignant renal cancers. The most important exogenic risk factors are smoking and obesity. Most presentations are incidental and, when systemic symptoms occur they are often due to metastases. The mortality rate is still 30% in this disease. The only curative treatment option is surgery. Until recently interferon alpha and/or interleukin-2 were standard treatments in the palliative setting, but efficacy was limited. But in the last years advances could be made. Targeted therapies like sunitinib could demonstrate a significant improvement in progression free survival. Moreover, there are now treatment options even in second line palliative treatment. Nevertheless there are still enough questions to be answered: the optimal sequential therapy, how long should we treat our patients and can we combine theses targeted therapies? Studies to answer all these burning questions are already ongoing.

Palliative chemotherapy for recurrent and metastatic esophageal cancer.

More than two-thirds of patients diagnosed with esophageal cancer will have unresectable disease. The objective of this article is to review the clinical trials utilizing cytotoxic chemotherapy in patients with recurrent and metastatic esophageal cancer. A computerized (MEDLINE) search was performed to identify papers published on this topic between 1966 and 2007. A total of 96 trials were subsequently identified. Two randomized trials compared palliative chemotherapy with best supportive care in 180 patients with advanced esophageal cancer. Effectiveness and side-effects were evaluated in 49 phase II studies and 3 randomized phase III trials. Combination chemotherapy as compared to monochemotherapy is associated with significantly higher response rates but nevertheless results in similar survival. CF (cisplatin and 5-fluorouracil) currently represents one of the most effective regimens for advanced esophageal cancer, while among the newer combinations, irinotecan or taxane-based regimens have also given promising results. Prognosis for the majority of patients, however, remains poor as increases in survival were moderate at best.

Antibiotic treatment is not effective in patients infected with Helicobacter pylori suffering from extragastric MALT lymphoma.

PURPOSE: Apart from anecdotal reports implicating Helicobacter pylori (HP) in the development of extragastric mucosa associated lymphoid tissue (MALT) lymphoma, no large scale prospective studies have been performed on this topic. PATIENTS AND METHODS: A total of 77 patients with extragastric MALT lymphoma were prospectively studied. The presence or absence of HP was tested by histology, urease breath test, and serology. Patients were also tested for hepatitis A, B, and C and autoimmune conditions along with assessment of MALT lymphoma-specific genetic changes. RESULTS: Evidence for infection with HP was present in 35 of 77 patients (45%), and three of 75 patients tested (4%) were positive for hepatitis C and one for hepatitis B. All patients with HP-infection underwent eradication, 16 before initiation of further therapy. Apart from one patient with lymphoma involving parotid and colon, who achieved regression of the colonic lesions, none of these 16 patients showed regression of the lymphoma after a median follow-up of 14 months (range, 8 to 48+ months) before initiation of definitive treatment. No correlation between HP-status, localization, stage, autoimmune diseases, and genetic findings was seen. CONCLUSION: In our series, HP-eradication was ineffective for treatment of extragastric MALT lymphomas. This finding, along with an infection rate of 45%-as could also be expected in the general Austrian population-suggests that HP does not play a role in the development of these lymphomas. Antibiotic treatment targeting HP should, therefore, be discouraged in patients with extragastric MALT lymphomas.
