Somatostatin receptor expression, tumour response, and quality of life in patients with advanced hepatocellular carcinoma treated with long-acting octreotide.

Octreotide may extend survival in hepatocellular carcinoma (HCC). Forty-one per cent of HCCs have high-affinity somatostatin receptors. We aimed to determine the feasibility, safety, and activity of long-acting octreotide in advanced HCC; to identify the best method for assessing somatostatin receptor expression; to relate receptor expression to clinical outcomes; and to evaluate toxicity. Sixty-three patients with advanced HCC received intramuscular long-acting octreotide 20 mg monthly until progression or toxicity. Median age was 67 years (range 28-81 years), male 81%, Child-Pugh A 83%, and B 17%. The aetiologies of chronic liver disease were alcohol (22%), viral hepatitis (44%), and haemochromatosis (6%). Prior treatments for HCC included surgery (8%), chemotherapy (2%), local ablation (11%), and chemoembolisation (6%). One patient had an objective partial tumour response (2%, 95% CI 0-9%). Serum alpha-fetoprotein levels decreased more than 50% in four (6%). Median survival was 8 months. Thirty four of 61 patients (56%) had receptor expression detected by scintigraphy; no clear relationship with clinical outcomes was identified. There were few grade 3 or 4 toxicities: hyperglycaemia (8%), hypoglycaemia (2%), diarrhoea (5%), and anorexia (2%). Patients reported improvements in some symptoms, but no major changes in quality of life were detected. Long-acting octreotide is safe in advanced HCC. We found little evidence of anticancer activity. A definitive randomised trial would identify whether patients benefit from this treatment in other ways.

Bisphosphonates for breast cancer.

BACKGROUND: Bone is the most common site of metastatic disease associated with breast cancer affecting more than half of women during the course of their disease. Bone metastases are a significant cause of morbidity due to pain, pathological fractures, hypercalcaemia and spinal cord compression, and contribute to mortality. Bisphosphonates, which inhibit osteoclast-mediated bone resorption, are standard care for tumour-associated hypercalcaemia, and have been shown to reduce bone pain, improve quality of life, and to delay skeletal events and reduce their number in patients with multiple myeloma. Several randomized controlled trials have evaluated the role of bisphosphonates in breast cancer. OBJECTIVES: To assess the effect of bisphosphonates on skeletal events, bone pain, quality of life and survival in women with early and advanced breast cancer. SEARCH STRATEGY: Randomized controlled trials were identified using the specialized register maintained by the Cochrane Breast Cancer Group (the search was applied to the databases Medline, Central/CCTR, Embase, CancerLit, and included handsearches from a number of other relevant sources). See: Cochrane Collaboration Collaborative Review Group in Breast Cancer search strategy. SELECTION CRITERIA: Randomized controlled trials evaluating skeletal events in women with metastatic breast cancer and early breast cancer comparing: 1. treatment with a bisphosphonate with the same treatment without a bisphosphonate 2. treatment with one bisphosphonate with treatment with a different bisphosphonate. DATA COLLECTION AND ANALYSIS: Studies were selected by two independent reviewers. Studies fulfilling the eligibility criteria were evaluated for quality, particularly concealment of allocation to randomized groups. Data were extracted from the published papers or abstracts independently by the two primary reviewers for each of the specified endpoints (skeletal events, bone pain, quality of life and survival). Data on skeletal events and survival were presented as numbers of events, risk ratios and ratios of event rates. Meta-analyses were based on the fixed-effects model (Mantel-Haenszel). Subjective qualitative ratings were used to summarize the quality of life and pain data. MAIN RESULTS: Twenty one randomized studies were included. All studies in advanced breast cancer included women with clinically evident bone metastases (osteolytic and/or mixed osteolytic/osteoblastic) by plain xray and/or radionucleotide bone scans. In nine studies that included 2189 women with advanced breast cancer and existing bone metastases, bisphosphonates reduced the risk of developing a skeletal event by 17% (RR 0.83; 95% confidence interval (CI) 0.78-0.89; P < 0.00001). This effect was more modest, but still highly significant if episodes of hypercalcaemia were excluded (10 studies, 2656 women, RR 0.85; 95% CI 0.79-0.91 P = 0.0001). Overall, intravenous bisphosphonates reduce the risk of developing a skeletal event by 17 % (95% CI 0.78-0.89) compared with oral bisphosphonates, which reduce the risk of developing a skeletal event by 16 % (95% CI 0.76-0.93). Of the currently available bisphosphonates, 4 mg IV zolendronate reduces the risk of developing a skeletal event by 41% (RR 0.59, 95% CI 0.42-0.82), compared with 33 % by 90 mg IV pamdronate (RR 0.77, 95% CI 0.69-0.87), 18 % by 6 mg IV ibandronate (RR 0.82, 95% CI 0.67-1.00), 14 % by 50mg oral ibandronate (RR 0.86, 95% CI 0.73-1.02) and 16 % by 1600 mg oral clodronate (RR 0.84, 95% CI 0.72-0.98). Compared with placebo or no bisphosphonate, with bisphosphonates the skeletal event rate was lower in all of 12 studies in women with clinically evident bone metastases (median reduction of 29%, range 14-48%); statistically significant reductions were reported in 10 trials (four intravenous pamidronate, two oral clodronate, one intravenous ibandronate and two oral ibandronate, a single intravenous zolendronate study). Studies of intravenous zolendronate, pamidronate and oral clodronate in women with advanced breast cancer and clinically evident bone metastases showed significant delays in the median time to a skeletal event. Event-free survival was also reported to be longer in women receiving 6 mg of ibandronate compared with controls. Compared with placebo or no bisphosphonate, with bisphosphonates significant improvements in bone pain were reported in seven studies (90 mg iv pamidronate, 4 mg iv zolendronate, 6 mg iv ibandronate, 1600 mg oral clodronate and 50 mg oral ibandronate). Eight studies tested the effect of bisphosphonates compared with placebo on patient-rated quality of life using a referenced scale. Improvements in global quality of life were reported in only the three studies of iv and oral ibandronate. Treatment with bisphosphonates does not appear to affect survival in women with advanced breast cancer. Intravenous zolendronate (4 mg) appeared to be as effective as pamidronate (90mg) when directly compared in a single randomized double-blind study, based on the risk of developing a skeletal related event, the median time to first skeletal event and skeletal morbidity rate (events per year). Updated re-evaluation of the primary data in the overall population, by multiple event analysis using the method of Anderson-Gill, showed a reduction in the risk of developing any skeletal complication (including hypercalcamia) of 20 % (zolendronate 4 mg compared with pamidronate 90 mg, RR = 0.80, 95% CI 0.66 - 0.97, p = 0.025), suggesting a possible advantage of zolendronate 4 mg compared with pamidronate 90 mg. In the three studies of bisphosphonates in 320 women with advanced breast cancer without clinically evident bone metastases, there was no significant reduction in the incidence of skeletal events (RR 0.99; 95% CI 0.67-1.47; P = 0.97). In the three studies of oral clodronate that included 1653 women with early breast cancer, there was no statistically significant evidence of reduction in the risk of developing skeletal metastases (RR 0.82; 95% CI 0.66-1.01; P = 0.07), or of visceral metastases (RR 0.95; 95% CI 0.80-1.12, p = 0.53). However there was evidence of improved survival (RR 0.82; 95% CI 0.69-0.97, p = 0.02). However there was statistically significant heterogeneity among these studies and a random effects meta-analysis emphasizes the uncertainty of this finding (RR 0.75; 95% CI 0.45 - 1.25; p = 0.19). Toxicity or adverse events were described in 18 of the 21 studies. In general, few serious adverse events were reported. Toxicity associated with bisphosphonates is generally mild and infrequent. Renal toxicity is the main issue with intravenous zolendronate and is dose (8 mg) and infusion time related (< 15 minutes). With daily oral calcium (500 mg) and vitamin D (300-400IU) no significant renal impairment or hypocalcamia was observed with a 15 minute infusion of 4 mg IV zolendronate compared with 90 mg pamidronate. Monitoring of renal function with every cycle of zolendronate was undertaken in all studies and is recommended in practice. No significant renal toxicity was observed with intravenous pamidronate or ibandronate. Mild gastrointestinal toxicity is the main toxicity with oral clodronate and oral ibandronate. AUTHORS' CONCLUSIONS: In women with advanced breast cancer and clinically evident bone metastases, the use of bisphosphonates (oral or intravenous) in addition to hormone therapy or chemotherapy, when compared with placebo or no bisphosphonates, reduces the risk of developing a skeletal event and the skeletal event rate, as well as increasing the time to skeletal event. Some bisphosphonates may also reduce bone pain in women with advanced breast cancer and clinically evident bone metastases and may improve global quality of life. The optimal timing of initiation of bisphosphonate therapy and duration of treatment is uncertain. In women with early breast cancer the effectiveness of bisphosphonates remains an open question for research.

Long-term outcome of radiological-guided insertion of implanted central venous access port devices (CVAPD) for the delivery of chemotherapy in cancer patients: institutional experience and review of the literature.

Central venous access port devices (CVAPD) are necessary for delivery of prolonged infusional chemotherapy or in patients with poor peripheral venous access. Previous studies of Hickman catheters report complication rates in about 45% of patients. Our aim was to assess the early and late complication rate, and duration that the CVAPD remained functional, following insertion by interventional radiologists in patients with solid tumours. A prospective study was undertaken in 110 consecutive patients who had insertion of 111 subclavian CVAPD. The median age of patients was 57 years (range 17-83), 64 were females; 68 patients (61%) had gastrointestinal tumours and 25 (23%) had breast cancer. CVAPD were successfully implanted in all but one patient. There were four (4%) immediate major complications: thrombosis 2 and pneumothorax 2. Nine patients (8%) had bruising or pain. Four devices (4%) became infected. In total, 100 CVAPD (90%) were either removed as planned at the end of treatment (n=23) after a median 203 days, or remained in situ for a median of 237 days (7-1133). Premature removal occurred in eight patients due to infection (n=4), thrombosis (n=3) or faulty device (n=1). Four patients were lost to follow-up. Radiological insertion of CVAPD is safe and convenient with low rates of complications.

Tamoxifen for hepatocellular carcinoma.

BACKGROUND: Hepatocellular carcinoma (primary liver cancer) is the third commonest cause of cancer mortality world-wide. Survival is poor for patients with advanced disease. Trials of tamoxifen for hepatocellular carcinoma have conflicting results. OBJECTIVES: To conduct a systematic review of the literature to assess the effect of tamoxifen on overall survival, quality-of-life, tumour response, and treatment toxicity in people with advanced hepatocellular carcinoma. SEARCH STRATEGY: We identified trials from The Cochrane Hepato-Biliary Group Controlled Trials Register (January 2004), The Cochrane Central Register of Controlled Trials on The Cochrane Library (Issue 3, 2003), and MEDLINE database (1966 to November 2003). We searched bibliographies of review articles and identified trials, and hand-searched abstracts from relevant other meetings. SELECTION CRITERIA: All randomised clinical trials of treatment with tamoxifen compared to a control treatment without tamoxifen in people with hepatocellular carcinoma, including trials of tamoxifen versus placebo, tamoxifen versus best supportive care, and tamoxifen plus other treatment versus the same other treatment alone. DATA COLLECTION AND ANALYSIS: Three independent reviewers selected studies for inclusion, rated them for methodologic quality components (generation of allocation sequence; allocation concealment; blinding; and follow-up), and extracted data on the specified outcomes. Hazard ratios were derived for overall survival where possible. Meta-analysis was performed using a fixed-effect model. MAIN RESULTS: Ten randomised trials randomising 1709 patients were included. Tamoxifen versus placebo/no intervention had no significant effect on overall survival (hazard ratio 1.05; 95% CI 0.94 to 1.16; P = 0.4). This comparison showed no statistical heterogeneity (P = 0.2 and I(2 ) = 25.9%). Subgroup analysis showed that tamoxifen tended to increase mortality in trials with three adequate/three methodological components (hazard ratio 1.15; 95% CI 0.99 to 1.34; P = 0.06), showed no significant effect in trials with two adequate/three methodological components (hazard ratio 1.00; 95% CI 0.84 to 1.18; P = 0.98), and tended to reduce mortality in trials with one or less adequate/three methodological components (hazard ratio 0.82; 95% CI 0.60 to 1.12; P = 0.2), although this may have been confounded by the use of higher doses of tamoxifen in the better quality trials. Tamoxifen was associated with adverse effects. One trial measured patient quality of life, but the results were not reported in detail. REVIEWERS' CONCLUSIONS: These data do not support the use of tamoxifen for patients with hepatocellular carcinoma. Further research on the effects of tamoxifen in hepatocellular carcinoma does not seem warranted.

Bisphosphonates for breast cancer.

BACKGROUND: Bone is the most common site of metastatic disease associated with breast cancer, and affects more than half of women during the course of their disease. Bone metastases are a significant cause of morbidity due to pain, pathological fractures, hypercalcaemia and spinal cord compression, and contribute to mortality. Bisphosphonates, which inhibit osteoclast-mediated bone resorption, are standard care for tumour-associated hypercalcaemia, and have been shown to reduce bone pain, improve quality of life, and to delay skeletal events and reduce their number in patients with multiple myeloma. Several randomized controlled trials have evaluated the role of bisphosphonates in breast cancer. OBJECTIVES: The aim of this systematic review was to identify, describe and summarize high-quality evidence regarding the effect of bisphosphonates on skeletal events, bone pain, quality of life and survival in women with early and advanced breast cancer. SEARCH STRATEGY: Randomized controlled trials were identified in the specialized register maintained by the secretariat of the Cochrane Breast Cancer Group (the search was applied to the databases Medline, Central/CCTR, Embase, CancerLit, and included handsearches from a number of other relevant sources). See: Cochrane Collaboration Collaborative Review Group in Breast Cancer search strategy. SELECTION CRITERIA: Randomized controlled trials evaluating skeletal events in women with metastatic breast cancer and in women with early breast cancer comparing: 1. treatment with a bisphosphonate with the same treatment without a bisphosphonate 2. treatment with one bisphosphonate with treatment with a different bisphosphonate. DATA COLLECTION AND ANALYSIS: Studies were selected by two independent reviewers. Studies fulfilling the eligibility criteria were evaluated for quality, particularly concealment of allocation to randomized groups. Data were extracted from the published papers or abstracts independently by the two primary reviewers for each of the specified endpoints (skeletal events, bone pain, quality of life and survival). Data on skeletal events and survival were presented as numbers of events, risk ratios and ratios of event rates. Meta-analyses were based on the fixed-effects model (Mantel-Haenszel). Subjective qualitative ratings were used to summarize the quality of life and pain data. MAIN RESULTS: From 37 reports considered in detail after screening of the 117 reports identified by our search, 19 randomized studies were included. In eight studies that included 1962 women with advanced breast cancer and existing bone metastases, bisphosphonates reduced the risk of developing a skeletal event by 14% (RR 0.86; 95% confidence interval (CI) 0.80-0.91; P < 0.00001). This effect was more modest, but still highly significant if episodes of hypercalcaemia were excluded (6 studies, 1553 women, RR 0.88; 95% CI 0.81-0.96; P = 0.004). For intravenous pamidronate the reduction in the risk of skeletal event was greatest with a dosage of 90 mg (RR 0.77; 95% CI 0.69-0.87). Oral bisphosphonates reduced the risk of a skeletal event by 17% (pooled RR 0.83; 95% CI 0.73-0.94, P = 0.004). Oral clodronate reduced the risk of a skeletal event by 16% in women with advanced breast cancer and clinically evident bone metastases (pooled RR 0.84; 95% CI 0.72-0.98; P = 0.03). Compared with placebo or no bisphosphonate, with bisphosphonates the skeletal event rate was lower in all of eight studies (median reduction of 30%, range 20-48%); statistically significant reductions were reported in six trials (three intravenous pamidronate, two oral clodronate and one intravenous ibandronate). All studies of intravenous pamidronate and oral clodronate in women with advanced breast cancer and clinically evident bone metastases showed significant delays in the median time to a skeletal event. Event-free survival was reported to be longer in women receiving 6 mg of ibandronate compared with control women. Compared with placebo or no bisphosphonate, with bisphosphonates significant improvements in pain were reported in four studies, and improvements in quality of life were reported in two studies. Treatment with bisphosphonates does not appear to affect survival in women with advanced breast cancer. Intravenous zolendronate (4 mg) appeared to have equivalent efficacy when compared with intravenous pamidronate in a single randomized double-blind study. In the three studies of bisphosphonates in 320 women with advanced breast cancer without clinically evident bone metastases, there was no significant reduction in the incidence of skeletal events (RR 0.99; 95% CI 0.67-1.47; P > 0.9). In three studies of oral clodronate that included 1680 women with early breast cancer, there was borderline evidence of a reduction in the risk of developing skeletal metastases (RR 0.73; 95% CI 0.55-0.98; P = 0.04), but there was significant heterogeneity among these studies (P = 0.035). Toxicity or adverse events were described in 14 of the 19 studies. In general, few adverse events were reported. REVIEWER'S CONCLUSIONS: In women with advanced breast cancer and clinically evident bone metastases, the use of bisphosphonates (oral or intravenous) in addition to hormone therapy or chemotherapy, when compared with placebo or no bisphosphonates, reduces the risk of developing a skeletal event and the skeletal event rate, as well as increasing the time toskeletal event. Bisphosphonates may also reduce bone pain in women with advanced breast cancer and clinically evident bone metastases. In women with early breast cancer the effectiveness of oral clodronate in reducing the incidence of bone metastases remains an open question for research.

Carboplatin and vinorelbine in untreated locally advanced and metastatic non-small cell lung cancer.

The aim of this study was to assess the activity and toxicity of carboplatin/vinorelbine combination chemotherapy in unresectable locally advanced and metastatic non-small cell lung cancer. Between April 1997 and June 1999 30 patients (22 M, eight F, median age 62) received treatment with carboplatin AUC 6 on day 1, and vinorelbine 25mg/m(2) on days 1, 8 and 15. Treatment was given every 28 days for six cycles unless progressive disease occurred. Twenty-three patients (77%) had stage IV disease, and seven (23%) stage IIIB. Ninety-three percent were WHO performance status 0-1. Twenty-three patients were fully assessable. Nine patients achieved partial responses (9/23, 39%) for an overall objective response rate of 9/30 (30%; 95% CI 15-49%). The median duration of response was 2.75 months (range 1-13 months). The median progression-free survival was 2 months and the median survival 5.25 months. The actuarial 1-year survival was 20%. The median number of cycles completed was two (range 1-6). Day 15 vinorelbine was administered in only 18% of cycles. The main toxicity was myelosuppression. WHO grade III/IV neutropenia was experienced in 50% of patients, however, there were only three episodes of febrile neutropenia. Eight patients required blood transfusion and one developed grade III thrombocytopenia. Treatment was ceased in one patient because of grade IV autonomic neuropathy. No patient had significant nausea and vomiting. There were no treatment-related deaths. These results indicate that carboplatin/vinorelbine is well tolerated and has similar activity to cisplatin/vinorelbine in patients with unresectable non-small cell lung cancer, however, the median survival was considerably shorter.

Patients' preferences for adjuvant chemotherapy in early breast cancer: a review of what makes it worthwhile.

Adjuvant chemotherapy for early breast cancer improves survival but is unpleasant and inconvenient. Women and clinicians need information about the magnitude of survival benefits considered sufficient to make the side-effects and inconvenience worthwhile. We sought studies that quantified the minimum required survival benefit by asking women who had experienced adjuvant chemotherapy. Four studies involving 512 women were appraised and summarised. All studies referred to chemotherapy given between 1980 and 1996, but the methods varied widely, especially the way in which women were recruited and questioned. However, the results were remarkably consistent. Most women said that small improvements in survival were sufficient to make adjuvant chemotherapy worthwhile. Women with dependants, social support, and milder side-effects judged smaller benefits worthwhile. Age, education, employment, and income status were not predictive of the women's responses. Optimum decision-making about the relative benefit of adjuvant chemotherapy requires up-to-date information from women receiving current chemotherapy and supportive regimens.

Systematic reviews of chemotherapy and endocrine therapy in metastatic breast cancer.

Metastatic breast cancer is incurable but often responsive to treatment. There is little evidence-based consenus on when to use which treatments, in what combination and for how long. Systematic reviews were performed on 12 prospectively defined, clinically relevant research questions to support the development of evidence-based clinical practice guidelines. A comprehensive search of Medline from 1966 to 1996 identified over 1800 controlled trials. Eligibility and data extraction were performed independently by two blinded reviewers. Trial results were summarised by ratios of median survivals (RMS) and P -values for survival curve comparisons with meta-analysis by weighted combination of these statistics. Sixty-five publications reporting 97 treatment comparisons were included. There was moderate evidence that more rather than fewer cycles of chemotherapy improved survival (RMS:1.23, P -0.01). The evidence did not support: higher rather than lower doses of chemotherapy (or of endocrine therapy); any one class of endocrine agent over all others; multiple endocrine agents over a single agent; or, combined chemotherapy and endocrine therapy over either single modality. Only six trials assessed quality of life revealing better quality of life with more rather than fewer cycles of chemotherapy and with standard rather than lower doses of chemotherapy. These systematic reviews reveal counterintuitive evidence useful to everyday practice, in particular that more rather than fewer cycles of chemotherapy lead to better quality of life and longer survival.

Quality-of-life assessment in health care research and practice.

This article reviews the different ways in which quality-of-life assessment has been applied to and has affected health care research and practice. A schema that describes the steps involved in the ongoing challenge of improving health outcomes is used to structure the review. The role of quality-of-life assessment is addressed with regard to: the identification of health problems, the evaluation of new treatments, the formulation of treatment guidelines and health policies, the delivery of optimal care in practice, and the assessment of outcomes in the wider community. The benefit of quality-of-life assessment has been demonstrated in a number of these areas (e.g., in identifying problems and evaluating treatments). Its role in other applications (e.g., in clinical practice to assess patients' needs) shows great promise and requires additional evaluation.

Resource implications of palliative chemotherapy for ovarian cancer.

PURPOSE: To describe the costs and outcomes of palliative chemotherapy in women with recurrent and refractory ovarian cancer from the perspective of a health care provider. PATIENTS AND METHODS: A retrospective study of 40 consecutive women who started second- or third-line chemotherapy for recurrent or refractory ovarian cancer between 1989 and 1992. Resource utilization from the commencement of second- or third-line chemotherapy until death or last follow-up evaluation was determined from a detailed chart review. All elements of care were recorded, including inpatient admissions, outpatient visits, chemotherapy drugs, nonchemotherapy drugs, radiation therapy, surgical procedures, investigations, and home care. Costs calculated using the hotel-approximation method are expressed in 1994 Canadian dollars. Actuarial estimates of cost and survival were used to account for censored observations. RESULTS: After a minimum follow-up period of 24 months, 36 of 40 women had died. The median survival duration of the group was 1.1 years from study entry and 1.7 years from first relapse. The women received a median of two regimens of chemotherapy (range, one to four) from study entry. They spent a median of 33 days as hospital inpatients (mean, 46; range, 0 to 185); 58% of these inpatient days were for symptomatic management and 32% were for chemotherapy. The mean cost per patient was $53,000 (median, $36,600; range, $4,800 to $162,900). The relationship between cost and survival duration was not linear--the cost per year was lowest for those who lived longest. Inpatient admissions, chemotherapy drugs, and outpatient visits accounted for 62%, 21%, and 8% of the total cost, respectively. The total costs attributable to chemotherapy were $24,000 (45% of total costs) and the total costs attributable to supportive care were $23,000 (43% of total costs). CONCLUSION: These data illustrate the cost of palliative management of recurrent and refractory ovarian cancer, which must be considered in the context of quality and duration of survival. They indicate the potential to improve cost efficiency by improving resource management, for example, by shifting from inpatient to outpatient chemotherapy, everything else being equal.

The take-home message: doctors' views on letters and tapes after a cancer consultation.

BACKGROUND: Patients' understanding of their disease and treatment varies in detail and accuracy. In order to participate in decisions about their care patients must understand, evaluate and retain complex information. METHODS: We canvassed doctors' views about the use of individualised letters and the use of audiotapes of the initial cancer consultation to improve doctor-patient communication. The study sample consists of doctors whose patients participated in a trial of the latter technique. RESULTS: One hundred sixty of 194 doctors (82%) responded to a mailed questionnaire. Sixty-one percent of respondents felt that providing patients with a tape of their initial cancer consultation would be beneficial, and 71% felt that an individualised letter would be better. General practitioners were more supportive of providing tape recordings to patients than were specialists (p = 0.057), but both groups favoured letters over tapes. Specialists were more concerned about the risks of providing tapes to patients than were general practitioners (p = 0.001), but only 13% of respondents felt that the risks were prohibitive. DISCUSSION: Wide support for providing individualised letters or tapes to patients, and copies to their doctors, indicate that the doctors surveyed believe that both doctor-patient and doctor-doctor communication could be improved by the use of these techniques.

Combination chemotherapy with cisplatin, vindesine and mitomycin-C for advanced, inoperable non-small-cell lung cancer.

OBJECTIVES: To assess the activity of chemotherapy with cisplatin, vindesine and mitomycin-C (PVM) in advanced non-small-cell lung cancer (NSCLC) and to test the feasibility of preemptive therapy with PVM. DESIGN AND SETTING: A phase II clinical trial of PVM in patients with NSCLC treated at the Royal Prince Alfred Hospital between June 1987 and July 1990. PATIENTS: Forty-one patients with advanced, inoperable or recurrent NSCLC--22 women, 19 men, with a median age of 51 years. Thirteen patients had been treated previously with radiotherapy and/or surgery; 18 had extrathoracic metastases. Four patients previously deemed inoperable were treated preemptively with PVM before proceeding to radical surgery. INTERVENTIONS: Cisplatin 100 mg/m2, vindesine 5 mg and mitomycin-C 8 mg/m2, all given intravenously on Day 1, with vigorous hydration and antiemetic therapy. Cycles were repeated every four weeks. MAIN OUTCOME MEASURES: Objective tumour response to treatment, patient survival time, time to treatment failure, and treatment toxicity. RESULTS: There was one complete tumour response to PVM and 15 partial responses; 14 patients had stable disease and nine had progressive disease--yielding an objective response rate (complete plus partial responses) of 39% (16/41; 95% confidence interval [CI], 24%-56%). Responses were documented in all histological subgroups, in both locally advanced and disseminated disease, and in recurrent disease. Median survival of the group was six months (95% CI, 5-10 months; range, 0.5-19+ months), and is unchanged by exclusion of the four patients treated before surgery. Seven of the 41 patients (17%) survived 12 months or longer. Median time to treatment failure in patients who had an objective response was six months (95% CI, 5-10 months). Grade 3 or 4 nausea and vomiting occurred in 21 patients (51%). Haematological, renal and neurological toxicity were not major problems; there were no deaths from treatment toxicity. CONCLUSION: PVM is an active regimen in advanced NSCLC and can produce durable remissions. The potential palliative effects of PVM in incurable disease must be weighed against the risk of subjective toxicity.
