PURPOSE:We developed and validated a brief, yet sensitive, 33-item general cancer quality-of-life (QL) measure for evaluating patients receiving cancer treatment, called the Functional Assessment of Cancer Therapy (FACT) scale. METHODS AND RESULTS:The five-phase validation process involved 854 patients with cancer and 15 oncology specialists. The initial pool of 370 overlapping items for breast, lung, and colorectal cancer was generated by open-ended interview with patients experienced with the symptoms of cancer and oncology professionals. Using preselected criteria, items were reduced to a 38-item general version. Factor and scaling analyses of these 38 items on 545 patients with mixed cancer diagnoses resulted in the 28-item FACT-general (FACT-G, version 2). In addition to a total score, this version produces subscale scores for physical, functional, social, and emotional well-being, as well as satisfaction with the treatment relationship. Coefficients of reliability and validity were uniformly high. The scale's ability to discriminate patients on the basis of stage of disease, performance status rating (PSR), and hospitalization status supports its sensitivity. It has also demonstrated sensitivity to change over time. Finally, the validity of measuring separate areas, or dimensions, of QL was supported by the differential responsiveness of subscales when applied to groups known to differ along the dimensions of physical, functional, social, and emotional well-being. CONCLUSION:The FACT-G meets or exceeds all requirements for use in oncology clinical trials, including ease of administration, brevity, reliability, validity, and responsiveness to clinical change. Selecting it for a clinical trial adds the capability to assess the relative weight of various aspects of QL from the patient's perspective.

Combination chemotherapy is frequently used in the therapy of advanced non-small-cell lung cancer (NSCLC), but late complications are rarely recognized because of the short survival of most patients. Of 119 patients with advanced NSCLC treated with cisplatin and other drugs, four patients developed acute nonlymphocytic leukemia (ANLL). All four patients received etoposide and cisplatin with or without vindesine. Leukemia was diagnosed at 13, 19, 28, and 35 months after start of treatment. Three patients had morphologic and/or cytogenetic features of acute leukemia with significant monoblastic involvement; the fourth patient had trilineage dysplasia and cytogenetic abnormalities more commonly associated with therapy-related leukemia. Detailed analysis of the subgroup who survived longer than 1 year (24 patients) suggests that high cumulative doses of etoposide are leukemogenic; the median etoposide dose was 6,795 mg/m2 (first year only) in the four leukemic patients compared with 3,025 mg/m2 in the 20 nonleukemic patients (P less than .01). The rate of ANLL was 0.30 per person-year after the first year (95% confidence limits 0.11 to 0.90), with a cumulative risk of 15% +/- 11% at 2 years, and 44% +/- 24% at 2.5 years. We conclude that high doses of etoposide are potentially leukemogenic, and can induce a syndrome with features of acute monoblastic leukemia de novo that is distinct from other secondary leukemias.

Fourteen previously untreated patients with metastatic small cell lung carcinoma (SCLC) were treated with carboplatin, 400 mg/m2, given as a 1-hour infusion every 28 days. Eleven patients had a partial response to therapy [response rate, 79% (95% confidence limits, 57%-100%)]. The median duration of response was 8 weeks (range, 4-41) and the median survival was 29 weeks (range, 11-68+). Hematologic toxicity was limited to one patient who developed World Health Organization (WHO) grade IV thrombocytopenia; no patient developed infection due to granulocytopenia. Nonhematologic toxicity was limited to WHO grade I and II nausea and vomiting. This study demonstrates that carboplatin is a highly active drug in SCLC with minimal toxicity. Future studies should evaluate its use in combination with other chemotherapeutic drugs in SCLC.

Twenty patients with disseminated cancer both untreated and previously treated received bialkylator chemotherapy, thiotepa, and cyclophosphamide and reinfusion of cryopreserved autologous bone marrow (ABMR). The cyclophosphamide dose was constant at 7.5 g/m2 over three days, while thiotepa was started at 1.8 mg/kg for three days in escalating dose by a modified Fibonacci schema to 7 mg/kg. The median time to recovery of more than 500 granulocytes and more than 50,000 platelets/microL was 18 and 27 days, respectively. Four patients died as a consequence of severe, overwhelming infections or progressive disease during their period of aplasia. Of the 18 evaluable patients, a complete response (CR) was achieved in three patients and a partial response (PR) in ten patients for an overall response rate of 72%. The median duration of response was 14 weeks. Other nonhematologic toxicities included nausea/vomiting, diarrhea, stomatitis, skin rash, and cardiomyopathy. The maximum tolerated dose (MTD) of thiotepa was 700 mg/m2 or 6 mg/kg for three doses. Although there are substantial toxicities associated with this regimen, high-dose thiotepa and cyclophosphamide produce high response rates in patients with disseminated cancer.

Twenty patients with Stage IIIM0 (T3N2) non-small cell lung cancer were treated with vindesine, etoposide, and Platinol (cisplatin) (ELETOP) chemotherapy in an attempt to decrease tumor size and increase resectability and survival. ELETOP chemotherapy induced a 70% response rate (all partial responses) within 6 weeks, and three patients were able to undergo curative resection. Toxicities with ELETOP were moderately severe, with leukocyte and platelet nadirs on day 15. This pilot study demonstrates the feasibility of protochemotherapy in non-small cell lung cancer.
