Phase I study of irinotecan and raltitrexed in patients with advanced astrointestinal tract adenocarcinoma

To determine the dose-limiting toxicities (DLT) and maximum tolerated dose (MTD) of irinotecan and raltitrexed given as sequential short infusions every 3 weeks, 33 patients with pretreated gastrointestinal adenocarcinoma (31 colorectal, 2 oesophagogastric) entered this open label dose-escalation study. For the first five dose levels patients received irinotecan 175–350 mg m–2followed by raltitrexed 2.6 mg m–2. Level VI was irinotecan 350 mg m–2plus raltitrexed 3.0 mg m–2, level VII was irinotecan 400 mg m–2plus raltitrexed 2.6 mg m–2; 261 courses were administered. Only one patient at dose levels I–V experienced DLT. At level VI, 5/12 patients experienced DLT: one had grade 3 diarrhoea and lethargy, one had grade 4 diarrhoea and one had lethargy alone. Two others had lethargy caused by disease progression. There was no first-cycle neutropenia. At level VII, 3/6 patients experienced dose-limiting lethargy, one also had grade 3 diarrhoea. Dose intensity fell from over 90% for both drugs at level VI to 83% for irinotecan and 66% for raltitrexed at level VII. Lethargy was therefore the DLT, and level VII the MTD. Pharmacokinetic data showed no measurable drug interaction; 6/30 patients (20%) had objective responses. This combination is active with manageable toxicity. Recommended doses for further evaluation are irinotecan 350 mg m–2and raltitrexed 3.0 mg m–2. © 2000 Cancer Research Campaig

Patterns of relapse in extrapulmonary small cell carcinoma: retrospective analysis of outcomes from two cancer centres

Objectives: We conducted a retrospective review of patients with extrapulmonary small cell carcinomas (EPSCCs) to explore the distribution, treatments, patterns of relapse and outcomes by primary site. Setting: We have reviewed the outcomes of one of the largest data sets of consecutive patients with EPSCC identified from two major cancer centres. Participants: Consecutive patients with a histopathological diagnosis of EPSCC from the two institutions were retrospectively identified. Primary and secondary outcome measures: Outcomes were evaluated including stage at presentation, treatments given, sites of relapse, time to distant relapse, progression-free survival and overall survival (OS). Results: From a total 159 patients, 114 received first-line chemotherapy, 80.5% being platinum-based. Response rate was 48%. Commonest primary sites were genitourinary and gynaecological. 44% of patients presented with metastatic disease. 55.9% relapsed with liver the commonest site, whereas only 2.5% developed brain metastases. Median OS was 13.4 months for all patients, 7.6 months and 19.5 months for those with metastatic and non-metastatic disease, respectively. Gynaecological and head and neck patients had significantly better OS compared to gastrointestinal patients. Conclusions: EPSCCs demonstrate high response rates to chemotherapy and high rates of distant metastases. Primary sites may influence prognosis, and survival is optimal with a radical strategy. Brain metastases are rare and we therefore do not recommend prophylactic cranial irradiation

Etiology and natural history of neutropenia in human immunodeficiency virus disease: a prospective study.

The objective of this prospective, observational study was to define the natural history of neutropenia in human immunodeficiency virus (HIV) disease. Eighty-seven consecutive patients developing neutropenia (absolute neutrophil count [ANC], <1000 cells/mm(3)) were recruited and closely followed for the duration of the episode. Episodes lasted a median of 13 days, with a mean ANC nadir of 660 cells/mm(3). Presumed or proven infection occurred in 12 (17%) of 71 evaluable subjects, and culture-proven infection occurred only in 6 (8%) of 71. Most of the episodes of neutropenia were brief, mild to moderate in nadir, and self-limiting without complications. Myelosuppressive therapies were implicated in almost all episodes. Serious infections occurred infrequently and were associated with low ANC nadirs but not with duration of the neutropenic episode. Low CD4(+) cell counts also increased the risk of infection complicating an episode of neutropenia

Modafinil for the treatment of fatigue in lung cancer: results of a placebo-controlled, double-blind, randomized trial

PURPOSE: Fatigue is a distressing symptom occurring in more than 60% of patients with cancer. The CNS stimulants modafinil and methylphenidate are recommended for the treatment of cancer-related fatigue, despite a limited evidence base. We aimed to evaluate the efficacy and tolerability of modafinil in the management of fatigue in patients with non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS: Adults with advanced NSCLC and performance status of 0 to 2, who were not treated with chemotherapy or radiotherapy within the last 4 weeks, were randomly assigned to daily modafinil (100 mg on days 1 to 14; 200 mg on days 15 to 28) or matched placebo. The primary outcome was change in Functional Assessment of Chronic Illness Therapy (FACIT) -Fatigue score from baseline to 28 days, adjusted for baseline fatigue and performance status. Secondary outcomes included safety and patient-reported measures of depression, daytime sleepiness, and quality of life. RESULTS: A total of 208 patients were randomly assigned, and 160 patients (modafinil, n = 75; placebo, n = 85) completed questionnaires at both baseline and day 28 and were included in the modified intention-to-treat analysis. FACIT-Fatigue scores improved from baseline to day 28 (mean score change: modafinil, 5.29; 95% CI, 2.57 to 8.02; placebo, 5.09; 95% CI, 2.54 to 7.65), but there was no difference between treatments (0.20; 95% CI, -3.56 to 3.97). There was also no difference between treatments for the secondary outcomes; 47% of the modafinil group and 23% of the placebo group stated that the intervention was not helpful. CONCLUSION: Modafinil had no effect on cancer-related fatigue and should not be prescribed outside a clinical trial setting. Its use was associated with a clinically significant placebo effect
