Irinotecan or FOLFIRI for 2nd line colorectal

Background Second-line treatment with irinotecan for advanced or metastatic colorectal cancer prolongs survival. It is uncertain whether irinotecan is better administered with 5- fluorouracil or alone in patients previously treated with a fluoropyrimidine. We compared toxicity (particularly diarrhoea), quality of life, and efficacy of combination chemotherapy and irinotecan in these patients. Methods In DaVINCI, a randomised phase II trial, patients with advanced colorectal cancer were randomly allocated to: combination therapy (FOLFIRI), irinotecan (180 mg/m2 IV over 90 min, day 1), 5-fluorouracil (400 mg/m2 IV bolus and 2400 mg/m2 by 46-hour infusion from day 1) and folinic acid (20 mg/m2 IV bolus, day 1), 2-weekly; or single-agent, irinotecan (350 mg/m2 IV over 90 min), 3-weekly. Toxicity was evaluated every treatment cycle; QOL and response 6 weekly. Analysis was by intention to treat. Results were also combined with those of other trials. Findings We randomised 44 patients to combination and 45 to single-agent. The most common toxicity was complete alopecia (single-agent 37%, combination 14%, P<0.02). Eight patients in the irinotecan arm and 4 in the combination arm had grade 3–4 diarrhoea (P=0.24). The treatment groups did not differ significantly in overall QOL changes, response rate, or progression free or overall survival. In a systematic review of 29 trials of second-line irinotecan-based treatment, single-agent irinotecan was associated with more diarrhoea and alopecia than the combination, but efficacy was similar. Interpretation Combination treatment compared with single-agent irinotecan appears to reduce the rateof complete alopecia and diarrhoea without compromising efficacy on clinical outcomes.Australasian Gastro-Intestinal Trials Grou

Scoping Research Report on Assistive Technology - On The Road For Universal Assistive Technology Coverage

Over one billion people – largely disabled people and older people – are currently in need of Assistive Technology (AT). By 2050, this number is predicted to double. Despite the proven advantages of AT for disabled and older people, their families, and society, there is still a vast and stubborn gap between the need and the supply; currently only 10% of those who need AT currently have access to it. This Scoping Research Report on Assistive Technology (AT) seeks to unpick and understand the multi-layered and multifaceted ways in which economic, social, and political factors interplay and interact to create barriers to AT for those who need it the most. Through primary and secondary research, they explore the current landscape, the limitations, and current initiatives, ultimately answering the question: “How best should a target intervention around AT sphere affect positive change for poor, disabled and older people in Global South priority countries?”. To understand this question, the research team asked two specific questions: What are the barriers which prevent access to AT for the people that need it, with a focus on those living in low resource settings within DFID priority Global South countries? How should DFID, in partnership with others best direct its intervention toward overcoming these barriers? The work reveals that, while levels of AT market development vary across countries, key barriers are common. These barriers can be classified into 5 main categories related to both supply and demand factors and across the 5Ps of People, Products, Provision, Personnel, and Policy. This work is part of the ‘Frontier Technology Livestreaming’ programm

A phase II study of weekly cisplatin, 6S-stereoisomer leucovorin and fluorouracil as first-line chemotherapy for elderly patients with advanced gastric cancer

The incidence of gastric cancer (GC) increases significantly after the fifth decade and palliative chemotherapy is the ultimate treatment in the majority of patients. We investigated safety and efficacy of a weekly regimen with cisplatin, fluorouracil and leucovorin as first-line chemotherapy for elderly patients with advanced GC. Chemotherapy-naive patients older than 65 years were considered eligible for study entry. Frail elderly patients were identified and excluded according to the following criteria: age >85 years, dependence in one or more activities of daily living (activities of daily living and instrumental activities of daily living scales), three or more comorbid conditions, one or more geriatric syndromes. Chemotherapy consisted of 1-day per week administration of intravenous cisplatin 35 mg m(-2), 6S-stereoisomer leucovorin 250 mg m(-2) and fluorouracil 500 mg m(-2) (PLF). Patients were re-evaluated after eight weekly cycles and six additional weekly administrations were planned for patients without disease progression. A 5-day subcutaneous filgrastim (5 mug Kg(-1) day(-1), days +1-+5) was used after the first treatment delay for neutropenia and maintained thereafter. In the whole group, the best intention-to-treat overall response rate was 43\% (95\% CI: 30-56\%). The time to disease progression and the median survival time were 5.3 and 8.6 months, respectively. Fatigue was the commonest nonhaematologic toxicity (71\% of the patients). Filgrastim was used in 30 patients who showed grade II (20 patients) or grade III (10 patients) neutropenia. Neither grade IV toxicity nor toxic deaths were observed. The weekly PLF regimen resulted safe and effective in elderly patients with advanced GC. This outpatient regimen is based on old and low-cost drugs and it may represent an alternative to new and more expensive combinations

Capecitabine and bevacizumab as first-line treatment in elderly patients with metastatic colorectal cancer

BACKGROUND: The efficacy and safety of capecitabine and bevacizumab in elderly patients with metastatic colorectal cancer (mCRC) considered unsuitable for receiving first-line chemotherapy with an irinotecan or oxaliplatin-based combination were assessed in a phase II, open, multicentre, uncontrolled study. METHODS: Treatment consisted of capecitabine 1250 mgm 2 (or 950 mgm 2 for patients with a creatinine clearance of 30–50ml min 1) twice daily on days 1–14 and bevacizumab (7.5 mg kg 1) on day 1 every 3 weeks. RESULTS: A total of 59 patients aged X70 years with mCRC were enrolled. In an intention-to-treat analysis, the overall response rate was 34%, with 71% of patients achieving disease control. Median progression-free survival and overall survival were 10.8 months and 18 months, respectively. In all, 32 patients (54%) had grade 3/4 adverse events (AEs), the most common being hand–foot syndrome (19%), diarrhoea (9%) and deep venous thrombosis (7%). Four patients died because of treatment-related AEs. A relationship was detected between creatinine clearance p50 ml min 1 and the development of non-bevacizumab-related grade 3/4 AEs. The incidence of bevacizumab-associated AEs (hypertension, thromboembolic events and proteinuria) was consistent with that of previous reports in elderly patients. CONCLUSION: Bevacizumab combined with capecitabine represents a valid therapeutic alternative in elderly patients considered to be unsuitable for receiving polychemotherapy.This study was supported by Hoffmann-La Roche, Nutley, NJ, USA

Randomised, non-comparative phase II study of weekly docetaxel with cisplatin and 5-fluorouracil or with capecitabine in oesophagogastric cancer: the AGITG ATTAX trial

BACKGROUND: Docetaxel administered 3-weekly with cisplatin and 5-fluorouracil leads to better survival than does standard therapy in patients with oesophagogastric cancer, but leads to high rates of haematological toxicity. Weekly docetaxel is associated with less haematological toxicity. This randomised phase II study tested weekly docetaxel-based combination chemotherapy regimens, with the aim of maintaining their activity while reducing toxicity. METHODS: Patients with histologically confirmed metastatic oesophageal or gastric carcinoma were randomised to receive weekly docetaxel (30 mg m(-2)) on days 1 and 8, cisplatin (60 mg m(-2)) on day 1, and 5-fluorouracil (200 mg m(-2) per day) continuously, every 3 weeks (weekly TCF, wTCF); or docetaxel (30 mg m(-2)) on days 1 and 8 and capecitabine (1600 mg m(-2) per day) on days 1-14, every 3 weeks (weekly TX, wTX). RESULTS: A total of 106 patients were enrolled (wTCF, n=50; wTX, n=56). Response rates, the primary end point, were 47% with wTCF and 26% with wTX. Rates of febrile neutropenia were low in each arm. Median progression-free and overall survival times were 5.9 and 11.2 months for wTCF and 4.6 and 10.1 months for wTX, respectively. CONCLUSION: Weekly TCF and TX have encouraging activity and less haematological toxicity than TCF administered 3-weekly. Weekly docetaxel-based combination regimens warrant further evaluation in this disease

Capecitabine and mitomycin C as third-line therapy for patients with metastatic colorectal cancer resistant to fluorouracil and irinotecan

Protracted venous infusion 5-fluorouracil (5FU) combined with mitomycin C (MMC) has demonstrated significant activity against metastatic colorectal cancer. Owing to potential synergy based upon upregulation of thymidine phosphorylase by MMC, the combination of capecitabine and MMC may improve outcomes in irinotecan-refractory disease. Eligible patients with progressive disease during or within 6 months of second-line chemotherapy were treated with capecitabine (1250 mg m−2 twice daily) days 1–14 every 3 weeks and MMC (7 mg m−2 IV bolus) once every 6 weeks. A total of 36 patients were recruited, with a median age of 64 years (range 40–77), and 23 patients (78%) were performance status 0–1. The objective response rate was 15.2%. In all, 48.5% of patients had stable disease. Median failure-free survival was 5.4 months (95% CI 4.6–6.2). Median overall survival was 9.3 months (95% CI: 6.9–11.7). Grade 3 toxicities were palmar-plantar erythema 16.7%, vomiting 8.3%, diarrhoea 2.8%, anaemia 8.3%, and neutropenia 2.8%. No patients developed haemolytic uraemic syndrome. Symptomatic improvement occurred for pain, bowel symptoms, and dyspnoea. Capecitabine in combination with MMC is an effective regimen for metastatic colorectal cancer resistant to 5FU and irinotecan with an acceptable toxicity profile and a convenient administration schedule
