A retrospective study of 37 patients with haematological malignancy (21 acute myeloid leukaemia, 11 acute lymphoid leukaemia, two lymphoma, two hairy cell leukaemia, one Hodgkin's disease) and histologically documented mucormycosis was conducted to evaluate the clinical characteristics and ascertain the factors which influenced the outcome from mycotic infection. Patients were admitted to 18 haematology divisions in tertiary care or university hospitals in Italy between 1987 and 1995. Fever, thoracic pain, dyspnoea and cough were the most frequent presenting symptoms. At the onset, 89% patients were neutropenic (neutrophil counts < 0.5 x 10(9)/l) with a median duration of previous neutropenia of 14 d (range 6-60). The most frequent sites of infection were lungs (81%), CNS (27%), sinus (16%), liver (16%) and orbital space (10%). Only three patients were asymptomatic. A correct in vivo diagnosis was made in only 13 (35%) patients. When performed, thoracic and cranial CT scan were the most useful diagnostic investigations. Despite the fact that 26 febrile patients were treated with empirical antifungal treatment, 28 of the 37 patients (76%) died from fungal infection at a median time of 17 d from the onset of clinical symptoms. Nine patients were cured by antifungal therapy plus, in five cases, radical surgery procedures. An analysis of factors influencing outcome demonstrated that the resolution of chemotherapy-induced neutropenia and prolonged treatment with amphotericin B and, if feasible, radical surgical debridement treatment, were significantly correlated with recovery from infection. Mucormycosis, a rare filamentous fungal infection that occurs most frequently in neutropenic acute leukaemia patients, is characterized by a high mortality rate. Extensive and aggressive diagnostic and therapeutic procedures are essential to improve the prognosis in these patients.

While mucositis and hand-foot syndrome are the main limiting toxicities of pegylated-liposomal doxorubicin, a small proportion of patients develop transient dyspnea at the initiation of drug infusion. Of the first 35 patients in a phase II study of pegylated-liposomal doxorubicin, three developed dyspnea, two low back pain and two pain at the site of tumor, within 1-5 min after starting the pegylated-liposomal doxorubicin infusion. The symptoms resolved within 5-15 min of stopping the infusion. In each case, the infusion was restarted without adverse effect. The mechanism of these symptoms is unclear. Because the dyspnea was reminiscent of that seen with hemodialysis neutropenia, complete blood counts were obtained in four of these patients approximately 2 min after the onset of symptoms. In all four patients, relative neutropenia was present (ANC 35, 3, 24 and 46% of pretreatment) that resolved by the end of the pegylated-liposomal doxorubicin infusion. Pegylated-liposomal doxorubicin stimulated neutrophil adhesion to human umbilical vein endothelial cells in vitro at concentrations predicted to be present in plasma during the initiation of treatment. Thus, pegylated-liposomal doxorubicin can induce an increase in neutrophil adhesion directly. We conclude that one mechanism of pegylated-liposomal doxorubicin-induced acute dyspnea is a transient sequestration of neutrophils in the pulmonary circulation, resulting in a decrease in compliance and associated dyspnea. In the patients in this study, these symptoms were transient, mild and not life threatening. Pegylated-liposomal doxorubicin is generally well tolerated and we do not routinely use premedications in patients receiving pegylated-liposomal doxorubicin.

MVP chemotherapy (mitomycin C 8 mg m(-2), courses 1, 2, 4 and 6, vinblastine 6 mg m(-2), cisplatin 50 mg m(-2)) is an active low-toxicity regimen in non-small-cell lung cancer (NSCLC). Based on the single-agent activity of these agents in SCLC, we have conducted a phase II trial of MVP in SCLC. Fifty chemo-naive patients with SCLC were entered in this trial. There were 33 men and 17 women with median age 66 years (range 46-83 years); 18 patients had limited disease (LD) and 32 extensive disease (ED). WHO performance status (PS) was: three patients PS 0, 33 patients PS 1, ten patients PS 2, four patients PS 3. A maximum of six cycles was given in responding patients. On completion of chemotherapy, patients with LD obtaining complete response (CR)/good partial response (PR) received thoracic irradiation and those obtaining CR were offered entry into the ongoing MRC Prophylactic Cranial Irradiation Trial. The overall response was 79% with 17% CR and 62% PR. For LD patients, 38% obtained CR but for ED only one patient achieved CR. Median response duration for LD patients was 8 months and for ED patients 5 months. Median survival was 10 months for LD patients and 6 months for ED patients. There was complete resolution of symptoms in 24%, partial improvement in 68%, no change in 2% and progressive symptoms in 6%. As regards toxicity, 24% developed WHO grade 3/4 neutropenia, 16% grade 3/4 thrombocytopenia and 6% significant hair loss. Two patients died during the first week of treatment with neutropenic infection. Quality of life using the EORTC questionnaire (QLC-C30) with lung cancer module demonstrated significant improvements from baseline levels in emotional and cognitive functioning, global QOL, of pain, dyspnoea and cough. MVP, an effective palliative regimen for NSCLC, is also active against SCLC with low toxicity and merits comparison with more toxic conventional schedules.

Aspergillosis is an infrequent but commonly fatal infection among HIV-infected individuals. We review 342 cases of pulmonary Aspergillus infection that have been reported among HIV-infected patients, with a focus on invasive disease. Invasive pulmonary aspergillosis usually occurs among patients with <50 CD4 cells/mm3. Major predisposing conditions include neutropenia and steroid treatment. Fever, cough, and dyspnea are each present in >60% of the cases. BAL is often suggestive, but biopsy specimens are necessary for definite diagnosis. Amphotericin B is the mainstay of treatment and mortality is > 80%. Avoiding neutropenia and judicious use of steroids may be helpful in prevention. Aggressive diagnostic approach, early initiation of treatment, adequate dosing of antifungals, and close follow-up may improve the currently dismal prognosis.

A late phase II clinical study of RP56976 (docetaxel), a new anticancer agent for advanced/recurrent head and neck cancer, was conducted in 29 institutions all over Japan as a multi-institutional cooperative study. Docetaxel was administered by 1 to 2-hour intravenous infusion at a dose of 60 mg/m2 every 3 to 4 weeks. Of 63 patients eligible in this study, 59 were judged as complete cases. Complete response (CR) was observed in 1 patient, partial response (PR) in 13, no change (NC) in 25, and progressive disease (PD) in 20, for an overall response rate of 22.2% (14/63, 95% CI: 12.7-34.5%) in eligible cases, and 23.7% (14/59, 95% CI: 13.6-36.6%) in complete cases. Previously treated patients showed a 17.9% (10/56) response rate, whereas treatment--naive patients showed a 57.1% (4/7) response rate. Among 46 patients who received prior chemotherapy, one CR and 7 PR were observed with a 17.4% response rate. Major hematological toxicities were leucopenia in 95.1% (> or = grade 3, 59.7%) and neutropenia in 90.3% (> or = grade 3, 79.0%). Other severe toxicities (> or = grade 3) included anorexia in 9.7% (6 cases), diarrhea in 3.2% (2 cases), dyspnea in 3.2% (2 cases), and fatigue in 3.2% (2 cases). One patient had a grade 3 interstitial pneumonia; however, symptoms were resolved by the administration of corticosteroids. During this study, one patient died due to multiple organ failure (MOF) caused by disseminated intravascular coagulation (DIC), and this case was reported as a therapy-related death. Based on these results, docetaxel is an active agent for treatment of head and neck cancer.

The efficacy and toxicity profile of gemcitabine was evaluated in this phase II study of chemonaive patients with locally advanced and metastatic non-small cell lung cancer (NSCLC). Eighty patients (62 males, 18 females) were entered into this study. The disease stage was IIIA in ten patients, IIIB in 32, and IV in 38 patients. The median age was 61 (range 41 - 78). Karnofsky performance status was > or = 80 in 88% of patients. All patients were chemonaive, but five patients had received prior radiotherapy and 34 patients had undergone prior surgery. Gemcitabine 1250 mg/m2 was given as a 30-min intravenous infusion on days 1, 8, and 15 of a 28-day cycle. Patients received up to nine cycles (median three cycles). Of 872 doses 815 (93%) were administered without dose delay or modification. Of the 80 patients enrolled, 76 were evaluable for efficacy analysis, and 16 patients had a partial response for an overall response rate of 21.1% (95% CI, 11.9-30.3%). A further 47 patients (61.8%) had stable disease. Partial responses were seen in eight of 41 stage III patients (19.5%) and in eight of 35 stage IV patients (22.9%). The median time to progressive disease was 4.6 months. Median survival for all 80 patients was 7.1 months. Haematological toxicity was mild with grade 3 4 neutropenia in 6.3% of patients, grade 3 thrombocytopenia in 3.8% of patients, and grade 3 anaemia in 2.5% of patients. Grade 3 non-laboratory toxicity was: somnolence (1.3% of patients), infection (1.3%), nausea and vomiting (6.4%) and dyspnoea (5.1%). This study confirms that single-agent gemcitabine is active in advanced NSCLC and its well-tolerated safety profile makes it particularly suited to outpatient use.

Because both vindesine and gemcitabine are active drugs in advanced non-small-cell lung cancer (NSCLC), with different modes of action and only partly overlapping toxicity, a phase II study was performed. Gemcitabine 1000 mg m(-2) was given on days 1, 8 and 15 every 4 weeks, while vindesine 3 mg m(-2) was administered weekly for 7 weeks, then every 2 weeks. A total of 42 patients with nonresectable NSCLC were included. The median age of patients was 56 years; 57% were men, 52% had adenocarcinoma, 31% squamous cell carcinoma and 17% had large-cell carcinoma. The performance status ranged from 0 to 2 with 83% in performance status 1. The majority (55%) had stage IV disease, while 40% had stage III B and 5% stage III A disease. WHO grade 3-4 leucopenia occurred in five patients (12%) and 9% had grade 4 neutropenia. Thrombocytopenia grade 3-4 was observed in six patients (15%). There were no septic death or bleeding episodes. One patient had a transient WHO grade 4 increase in bilirubin, and four patients had a decrease in glomerular filtration rate below the normal limit; one of these patients developed a non-reversible renal insufficiency. Ten patients (24%) complained of dyspnoea of uncertain mechanism, possibly involving bronchoconstriction. There were one complete and seven partial responses among 40 assessable patients (20%, 95% confidence limits 9-36%). Median response duration was 31 weeks (range 11-83 weeks) and median survival time 31 weeks (range 2-171 weeks). The current combination of gemcitabine and vindesine does not appear to be promising for further examination because of the toxicity and somewhat disappointing activity.

CPT-11 + ADM therapy (CPT-11 40 mg/body x 2 days; Day 1 & 2, combined with ADM 20 to 60 mg/body x 1 day; Day 3) was given to four patients with relapsed and advanced non-Hodgkin's lymphoma, which was refractory to conventional chemotherapies. The symptoms of the patients at the beginning of CPT-11 + ADM therapy were fever (in two cases), dyspnea due to pleural effusion (in two), severe backache (in one), and jaundice with splenomegaly (in one). Their Karnofsky performance scales were 20 or 30%. Soon after the initiation of CPT-11 + ADM therapy, their clinical conditions improved dramatically, and they obtained a partial remission lasting 3.5 to 9 months. During the period of controlling lymphomas by this therapy, all patients had some time at home for 2 to 8 months. The adverse effects were vomiting, diarrhea, neutropenia and thrombocytopenia, but no lethal infection or hemorrhage was seen. We conclude that CPT-11 + ADM therapy is very useful for improvement of QOL and life prolongation of patients with non-Hodgkin's lymphoma, which is refractory to conventional chemotherapies and is even disseminated.

This study was designed to assess the activity of oral topotecan (TPT) in patients with advanced non-small cell lung cancer previously untreated with chemotherapy. Eligible patients had inoperable stage III or stage IV non-small cell lung cancer and were chemotherapy-naive. Other inclusion criteria were Eastern Cooperative Oncology Group performance status 0, 1, or 2, adequate bone marrow, and renal and hepatic function. Of 30 patients, 29 were assessable for response. Oral TPT was administered for 5 days every 21 days for up to six cycles unless disease progression or unacceptable toxicity occurred. Patients received a dose of 2.3 mg/m2/day for the first cycle. Dose modification for subsequent cycles was based on tolerability. Patients completed symptom questionnaires every 3 weeks. Pharmacokinetics were evaluated in all patients during cycle 1. Three patients had radiological responses with a reduction in tumor size of 30-40%. No patients achieved complete or partial responses to treatment. Thirteen patients had a stable disease (43.3%), and the median survival was 39.9 weeks with a 1-year survival of 33.3%. At the time of analysis, 27 patients had died. Median time to progression was 12.3 weeks. Treatment was well tolerated. A total of 125 cycles of treatment were completed. Twelve patients (40%) experienced grade III/IV neutropenia. Five patients (16.6%) had grade III/IV anemia. There were two episodes of grade III/IV thrombocytopenia. The main nonhematological toxicities consisted of grade III nausea (13%) and grade III vomiting (13%). The most frequently reported disease-related symptoms at baseline were dyspnea, cough, and fatigue. There was a subsequent improvement in patient scores of dyspnea in 17% of patients, 31% showed improvement in cough, and 32% showed improvement in fatigue. The mean area under the curve of TPT following 2.3 mg/m2 p.o. was 51.6 ng.h/ml (%SD, 25%). The area under the curve of TPT on day 1 of the first cycle was correlated with the percentage fall in leukocytes. Although oral TPT at the applied dose and schedule showed modest activity as a single agent, almost one-half of the patients had a stable disease, and median time to progression was 12.3 weeks. The overall median survival was a promising 39.9 weeks, and useful palliation of symptoms was seen.

Our purpose in this study was to determine the efficacy and toxicity of losoxantrone (DuP-941), an anthrapyrazole, in patients with metastatic hormone-refractory prostate cancer. Patients with metastatic prostate cancer progressing on androgen ablation therapy without demonstrable antiandrogen withdrawal response were treated with losoxantrone 50 mg/m2 i.v. bolus every 21 days. All of the patients had elevated serum prostate-specific antigen (PSA) before study entry and had no prior chemotherapy. Forty-three assessable patients were entered. The median age was 70.6 years (range, 53.9-85.9), median Karnofsky performance scale (KPS), 70% (50-90%), and the median serum PSA, 173 microg/liter (12.5-11,140). The median number of courses was 4 (1-9). Five patients (25%) had a partial response as defined by >50% decline in the serum PSA. Two of nine patients with measurable disease had partial responses and three had minor responses. Thirty percent of patients had improvement in KPS and 37% had an improvement in symptoms with decrease in pain and/or decrease in analgesic requirement. Nonhematological grade 3 and 4 toxicities were one each of grade 3 headache, grade 4 hypocalcemia, grade 3 hyperbilirubinemia, and grade 3 dyspnea. Twenty-six patients (60%) had grade 3 or 4 absolute neutropenia. In conclusion, losoxantrone demonstrated a partial biochemical response rate of 25%, response in measurable disease sites in 22%, and improvement in clinical symptoms in one-third of patients. In this study, PSA increase was not necessarily associated with lack of palliative response.
