Background-Small cell lung cancer (SCLC) represents about 20% of primary lung tumours and the costs associated with the management of SCLC can be significant. The main objective of this study was to obtain information on current patterns of care and associated resource use and costs for patients with SCLC from initial diagnosis and treatment phase, throughout disease progression and terminal care. Methods-A 4 year retrospective patient chart analysis (1994-7) was conducted on a consecutive series of 109 patients diagnosed with SCLC in two Newcastle hospitals. For this consecutive series of patients all details about care received including tests and procedures, treatment, and medication from diagnosis till death were recorded. Pathways of care and forms were designed to enable resource use to be captured for diVerent disease phases. Unit costs were determined from a variety of sources including the Newcastle Hospitals NHS Trust Finance Department and the British National Formulary. Results-The average total cost per patient calculated for the full cohort of 109 patients was £11 556. Initial treatment was the most resource use intensive constituting 48.2% of the total cost. The major cost element throughout all disease phases was hospitalisation. Twenty eight percent of the total costs of care occur after recurrence of the disease until death, of which 73% are generated by terminal care. Conclusion-The results of this retrospective medical chart analysis show that the costs of care of SCLC are considerable, although the variability between patients in terms of the type and quantity of resource use is very high. Analyses such as this provide a useful insight into resources used in actual clinical practice. (Thorax 2001;56:785-790)

We evaluated the risk of acute nonlymphocytic leukemia, acute myelodysplastic syndrome, and preleukemia in 3633 patients with gastrointestinal cancer who were treated in nine randomized clinical trials. Among 2067 patients given semustine (methyl-CCNU) as adjuvant therapy, leukemic disorders developed in 14, whereas only one leukemic disorder (acute nonlymphocytic leukemia) occurred among 1566 patients given other therapies (relative risk = 12.4; 95 per cent confidence interval = 1.7 to 250). The six-year cumulative mean risk (+/- S.E.) of acquiring a leukemic disorder after treatment with semustine was 4.0 +/- 2.2 per cent; the incidence rate was 2.3 cases per 1000 persons per year. Risk increased significantly with time after treatment. The risk of leukemic disorders did not differ according to sex, race, age at treatment, or initial tumor type, nor was it enhanced by concomitant radiotherapy or immunotherapy. In addition, no excess of acute nonlymphocytic leukemia was seen in 44,370 patients treated for gastrointestinal cancer in Connecticut during the period 1935 to 1974, before the advent of nitrosourea chemotherapy. This study provides quantitative evidence that nitrosoureas are leukemogenic in human beings and confirms previous observations that adjuvant chemotherapy with alkylating agents may increase the risk of leukemia.

We have tested methyl glyoxal bis‐guanyl hydrazone (NSC 32946) for antitumor activity in patients with colorectal carcinoma and non‐small cell bronchogenic carcinoma. The drug dose was 500 mg/m2 administered by single weekly injection, and with a provision dose escalation. No responses were seen in 38 evaluable patients with colorectal cancer, including 17 who had received no prior chemotherapy. Three responses were seen among 42 patients with bronchogenic carcinoma. These included one each with epidermoid carcinoma, adenocarcinoma and large cell anaplastic carcinoma. None of these responders had received prior chemotherapy. Toxicity of the drug was predominantly gastrointestinal, namely nausea, vomiting and diarrhea, and tended to increase with repeated drug doses. Neurologic symptoms of various sorts were also prominent. We conclude that methyl‐G is of marginal benefit in this dose and schedule to patients with bronchogenic carcinoma.
