[Adverse obstetric and perinatal outcome with in vitro fertilization technology: A French nationwide population-based study]. / Risques de morbidité maternelle et périnatale en fécondation in vitro : une étude nationale de cohorte française.

OBJECTIVES: The objective of this study was to quantify the risk of maternal and perinatal morbidity with in vitro fertilization (IVF) technology compared to non-IVF pregnancies in a recent French national cohort. METHOD: The data was extracted from the hospital information data system, including all pregnancies with a delivery from 2013 to 2016. The risks of preterm birth, maternal morbidity (venous and arterial thrombosis, gestational diabetes, vascular disorders, placenta previa, placenta abruption), hypotrophy and congenital malformation were compared in both groups in univariate and multivariate analysis after adjustment on the characteristics of women (age, parity, obesity, tobacco dependence, history of diabetes or high blood pressure), multiple deliveries and sex of children. RESULTS: In all, 2,875,662 pregnancies and 2,922,712 births were analyzed, of which 49,224 were derived from IVF (1.7%). In multivariate analysis, all risks were significantly higher in IVF: premature deliveries (ORajusted=1.28; CI95%=1.24-1.32), maternal morbidity (ORajusted=1.24; CI95%=1.21-2.28), (mainly for thrombosis venous, placenta previa and placenta abruption). The risks of hypotrophy (ORajusted=1.13; CI95%=1.10-1.16) and congenital malformations (ORajusted=1.11; CI95%=1.05-1.17) were slightly increased. CONCLUSION: The results of this study on a large cohort of recent births in France confirm that there was an increased risk of maternal and perinatal morbidities in IVF. These risks were similar to those published in the international literature. This study is the starting point for a forthcoming surveillance.

Impact of physical activity on fatigue and quality of life in people with advanced lung cancer: a randomized controlled trial.

BACKGROUND: Physical activity (PA) improves fatigue and quality of life (QOL) in cancer survivors. Our aim was to assess whether a 2-month PA intervention improves fatigue and QOL for people with advanced lung cancer. METHODS: Participants with advanced lung cancer, Eastern Cooperative Oncology Group performance status (PS) ≤2, >6 months life expectancy, and ability to complete six-min walk test, were stratified (disease stage, PS 0-1 versus 2, centre) and randomized (1:1) in an open-label study to usual care (UC) (nutrition and PA education materials) or experimental intervention (EX): UC plus 2-month supervised weekly PA and behaviour change sessions. Assessments occurred at baseline, 2, 4, and 6 months. The primary endpoint was fatigue [Functional Assessment of Cancer Therapy-Fatigue (FACT-F) questionnaire] at 2 months. The study was designed to detect a difference in mean FACT-F subscale score of 6. Analysis was intention-to-treat using linear mixed models. RESULTS: We recruited 112 patients: 56 (50.4%) were randomized to EX, 55(49.5%) to UC; 1 ineligible. Male 55%; median age 64 years (34-80); 106 (96%) non-small cell lung cancer; 106 (95.5%) stage IV. At 2, 4 and 6 months, 90, 73 and 62 participants were assessed, respectively, with no difference in attrition between groups. There were no significant differences in fatigue between the groups at 2, 4 or 6 months: mean scores at 2 months EX 37.5, UC 36.4 (difference 1.2, 95% CI - 3.5, 5.8, P = 0.62). There were no significant differences in QOL, symptoms, physical or functional status, or survival. CONCLUSIONS: Adherence to the intervention was good but the intervention group did not increase their PA enough compared to the control group, and no difference was seen in fatigue or QOL.

Cytokine profiling of docetaxel-resistant castration-resistant prostate cancer.

BACKGROUND: Docetaxel improves symptoms and survival in metastatic castration-resistant prostate cancer (CRPC). However, ∼50% of patients are chemoresistant. This study examined whether changes in cytokine levels predict for docetaxel resistance in vitro and in a clinical cohort. METHODS: PC3 cells or their docetaxel-resistant subline (PC3Rx) were co-cultured with U937 monocytes, with and without docetaxel treatment, and cytokine levels were measured. The circulating levels of 28 cytokines were measured pre-/post cycle 1 of docetaxel from 55 men with CRPC, and compared with prostate-specific antigen (PSA) response. RESULTS: PC3Rx-U937 co-culture expressed more cytokines, chiefly markers of alternative macrophage differentiation, compared with PC3-U937 co-culture. Docetaxel treatment enhanced cytokine production by PC3Rx-U937 co-culture, while reducing cytokine levels in PC3-U937. In patients, changes in the levels of seven circulating cytokines (macrophage inhibitory cytokine 1 (MIC1), interleukin (IL)-1ra, IL-1ß, IL-4, IL-6, IL-12 and IFNγ) after cycle 1 of docetaxel were associated with progressive disease (all P<0.05). The combination of changes in MIC1, IL-4 and IL-6 most strongly predicted PSA response (P=0.002). CONCLUSIONS: In vitro studies suggest docetaxel resistance is mediated, at least in part, by cytokines induced by the interaction between the docetaxel-resistant tumour cells and macrophages. Early changes in circulating cytokine levels were associated with docetaxel resistance in CRPC patients. When considered together, these data suggest a significant role for the inflammatory response and macrophages in the development of docetaxel resistance in CRPC.

Methylated Glutathione S-transferase 1 (mGSTP1) is a potential plasma free DNA epigenetic marker of prognosis and response to chemotherapy in castrate-resistant prostate cancer.

BACKGROUND: Glutathione S-transferase 1 (GSTP1) inactivation is associated with CpG island promoter hypermethylation in the majority of prostate cancers (PCs). This study assessed whether the level of circulating methylated GSTP1 (mGSTP1) in plasma DNA is associated with chemotherapy response and overall survival (OS). METHODS: Plasma samples were collected prospectively from a Phase I exploratory cohort of 75 men with castrate-resistant PC (CRPC) and a Phase II independent validation cohort (n=51). mGSTP1 levels in free DNA were measured using a sensitive methylation-specific PCR assay. RESULTS: The Phase I cohort identified that detectable baseline mGSTP1 DNA was associated with poorer OS (HR, 4.2 95% CI 2.1-8.2; P<0.0001). A decrease in mGSTP1 DNA levels after cycle 1 was associated with a PSA response (P=0.008). In the Phase II cohort, baseline mGSTP1 DNA was a stronger predictor of OS than PSA change after 3 months (P=0.02). Undetectable plasma mGSTP1 after one cycle of chemotherapy was associated with PSA response (P=0.007). CONCLUSIONS: We identified plasma mGSTP1 DNA as a potential prognostic marker in men with CRPC as well as a potential surrogate therapeutic efficacy marker for chemotherapy and corroborated these findings in an independent Phase II cohort. Prospective Phase III assessment of mGSTP1 levels in plasma DNA is now warranted.

Circulating microRNAs are associated with docetaxel chemotherapy outcome in castration-resistant prostate cancer.

BACKGROUND: Docetaxel is the first-line chemotherapy for castration-resistant prostate cancer (CRPC). However, response rates are ∼50% and determined quite late in the treatment schedule, thus non-responders are subjected to unnecessary toxicity. The potential of circulating microRNAs as early biomarkers of docetaxel response in CRPC patients was investigated in this study. METHODS: Global microRNA profiling was performed on docetaxel-resistant and sensitive cell lines to identify candidate circulating microRNA biomarkers. Custom Taqman Array MicroRNA cards were used to measure the levels of 46 candidate microRNAs in plasma/serum samples, collected before and after docetaxel treatment, from 97 CRPC patients. RESULTS: Fourteen microRNAs were associated with serum prostate-specific antigen (PSA) response or overall survival, according to Mann-Whitney U or log-rank tests. Non-responders to docetaxel and patients with shorter survival generally had high pre-docetaxel levels of miR-200 family members or decreased/unchanged post-docetaxel levels of miR-17 family members. Multivariate Cox regression with bootstrapping validation showed that pre-docetaxel miR-200b levels, post-docetaxel change in miR-20a levels, pre-docetaxel haemoglobin levels and visceral metastasis were independent predictors of overall survival when modelled together. CONCLUSIONS: Our study suggests that circulating microRNAs are potential early predictors of docetaxel chemotherapy outcome, and warrant further investigation in clinical trials.

Phosphorylated Akt expression is a prognostic marker in early-stage non-small cell lung cancer.

AIMS: To determine the prognostic significance of pAkt expression in order to identify high-risk stage IB patients with non-small cell lung cancer (NSCLC) in an exploratory study. METHODS: We identified 471 consecutive patients with stage IB primary NSCLC according to the American Joint Commission on Cancer 6th edition tumour-node-metastasis (TNM) staging system, who underwent surgical resection between 1990 and 2008. Patients who received neoadjuvant or adjuvant treatments were excluded. Pathology reports were reviewed, and pathological characteristics were extracted. Expression of phosphorylated Akt (pAkt) in both cytoplasmic and nuclear locations was assessed by immunohistochemistry, and clinicopathological factors were analysed against 10-year overall survival using Kaplan-Meier and Cox proportional hazards model. RESULTS: 455 (96.6%) cancers were adequate for pAkt immunohistochemical analysis. The prevalence of pAkt expression in the cytoplasm and nucleus of the cancers was 60.7% and 43.7%, respectively. Patients whose cancers expressed higher levels of cytoplasmic pAkt had a trend towards longer overall survival than those with lower levels (p=0.06). Conversely, patients whose cancers expressed higher levels of nuclear pAkt had a poorer prognosis than those with lower levels of expression (p=0.02). Combined low cytoplasmic/high nuclear expression of pAkt was an independent predictor of overall survival (HR=2.86 (95% CI 1.35 to 6.04); p=0.006) when modelled with age (HR=1.05 (95% CI 1.03 to 1.07); p<0.001), extent of operation (HR=2.11 (95% CI 1.48 to 3.01); p<0.001), visceral pleural invasion (HR=1.63 (95% CI 1.24 to 2.15); p<0.001), gender, tumour size, histopathological type and grade (p>0.05). CONCLUSIONS: Level of expression of pAkt in the cytoplasm and nucleus is an independent prognostic factor that may help to select patients with high-risk disease.

Randomised, double-blind trial of carboplatin and paclitaxel with daily oral cediranib or placebo in patients with advanced non-small cell lung cancer: NCIC Clinical Trials Group study BR29.

INTRODUCTION: This randomised double-blind placebo-controlled study evaluated the addition of cediranib, an inhibitor of vascular endothelial growth factor receptors 1-3, to standard carboplatin/paclitaxel chemotherapy in advanced non-small cell lung cancer. METHODS: Eligible patients received paclitaxel (200mg/m(2)) and carboplatin (area under the concentration time curve 6) intravenously every 3 weeks. Daily oral cediranib/placebo 20mg was commenced day 1 of cycle 1 and continued as monotherapy after completion of 4-6 cycles of chemotherapy. The primary end-point of the study was overall survival (OS). The trial would continue to full accrual if an interim analysis (IA) for progression-free survival (PFS), performed after 170 events of progression or death in the first 260 randomised patients, revealed a hazard ratio (HR) for PFS of ⩽ 0.70. RESULTS: The trial was halted for futility at the IA (HR for PFS 0.89, 95% confidence interval [CI] 0.66-1.20, p = 0.45). A final analysis was performed on all 306 enrolled patients. The addition of cediranib increased response rate ([RR] 52% versus 34%, p = 0.001) but did not significantly improve PFS (HR 0.91, 95% CI 0.71-1.18, p = 0.49) or OS (HR 0.94, 95% CI 0.69-1.30, p=0.72). Cediranib patients had more grade 3 hypertension, diarrhoea and anorexia. CONCLUSIONS: The addition of cediranib 20mg daily to carboplatin/paclitaxel chemotherapy increased RR and toxicity, but not survival.

Better estimates of survival for patients considering adjuvant chemotherapy after surgery for early non-small-cell lung cancer.

INTRODUCTION: The aim of this study was to summarise and describe survival data from contemporary randomised trials of platinum-based adjuvant chemotherapy for patients with non-small-cell lung cancer (NSCLC). The goal was to assist clinicians to provide better estimates of survival for patients considering adjuvant chemotherapy following surgical resection for NSCLC. METHODS: Randomised trials of cisplatin-based adjuvant chemotherapy for resected NSCLC were identified. Survival rates at 1, 2, 5, 7 and 10 years and the following percentiles (scenario): 90th (worst case), 75th (lower typical), median, 25th (upper typical) and 10th (best case) were extracted from each overall survival (OS) curve. RESULTS: Thirty-eight OS curves from 19 trials (7042 patients) were analysed. With adjuvant chemotherapy, the median OS rate (interquartile range) at 1 year was 91% (85-95), 2 years was 73% (69-88), 5 years was 61% (45-65) and 7 years was 49% (38-65). With observation only, the median OS rate (interquartile range) at 1 year was 88% (83-92), 2 years was 74% (65-82), 5 years was 55% (42-58) and 7 years was 40% (34-45). In both arms, survival rates at 2, 5 and 7 years were well estimated by raising the 1-year survival rate to the power of two, five and seven respectively. Few trials reported survival rates at 10 years. CONCLUSION: Simple percentages and their powers provide a useful starting point for estimating and describing survival to patients considering adjuvant chemotherapy after surgery for NSCLC.

A phase II study of fenretinide in patients with hormone refractory prostate cancer: a trial of the Cancer Therapeutics Research Group.

PURPOSE: Fenretinide is a synthetic retinoid with activity in prostate cancer and other cell lines. The aim of this study was to assess the efficacy and tolerability of fenretinide in chemotherapy-naïve men with hormone refractory prostate cancer. METHODS: Eligibility criteria included hormone refractory prostate cancer with a rising PSA at least 6 weeks after peripheral anti-androgen withdrawal, ECOG performance status (PS) 0-1, and no prior chemotherapy. Fenretinide was administered orally at 900 mg m(-2) twice daily for 7 of every 21 days. PSA was measured before each cycle. The primary endpoint was a > or =50% reduction in PSA maintained for at least 3 weeks; secondary endpoints included duration of PSA response, time to treatment failure (TTF: treatment stopped for progression or toxicity) and adverse events (AE). RESULTS: Twenty seven pts were recruited from 7 centres over 27 months. Median age was 74 (range 49-86), median baseline PSA was 129 (range 19-1,000), and 70% had a PS of 0. The median number of cycles received was 2 (range 0-11) and 20 pts completed at least 1 cycle. One pt (4%) achieved a 50% reduction in PSA lasting 39 days and 15 pts (56%) had not progressed within 6 weeks of starting fenretinide. The median TTF was 54 days (IQR 19-73): 22 (81%) failed with tumour progression, 3 (11%) failed with toxicity and 2 (7%) never commenced the drug. Grade 3 rash occurred in 1 patient, all other AE were grade 1 or 2. The most common AE were nausea (40%), hot flushes (36%), constipation (32%) and nyctalopia (32%). CONCLUSION: High-dose fenretinide had limited anti-tumour activity in patients with advanced hormone refractory prostate cancer: further evaluation in this setting is not warranted.

The CDK inhibitors: potential targets for therapeutic stem cell manipulations?

Therapies involving adult stem cells are dependent upon sufficient expansion of these cells to repopulate or replace the diseased tissue and are consequently hindered by their relatively quiescent phenotype. Cellular proliferation is governed by the cyclin-dependent kinases, which in a complex with a corresponding cyclin, phosphorylate a number of downstream mediators to drive the cell through the cell cycle. In turn, biochemical activities of the cyclin-dependent kinases are regulated by two families of cyclin-dependent kinase inhibitors, which have been shown to be potent cell intrinsic blocks of adult stem cell proliferation in multiple tissue types. In contrast to normal stem cells, inappropriate regulation of the cell cycle in cancer stem cells may underlie tumorigenesis and failure of conventional chemotherapeutics to fully eradicate a tumor. Thus, definition of the roles of the cyclin-dependent kinase inhibitors in normal and cancer stem cells may permit the development of novel strategies for adult stem cell expansion and therapies specifically targeted to cancer stem cells.

Disarming the guarded prognosis: predicting survival in newly referred patients with incurable cancer.

People affected by cancer want information about their prognosis but clinicians have trouble estimating and talking about it. We sought to determine the nature and accuracy of medical oncologists' estimates of life expectancy in newly referred patients with incurable cancer. With reference to each patient, medical oncologists estimated how long they thought 90, 50, and 10% of similar patients would live. These proportions were chosen to reflect worst case, predicted, and best case scenarios suitable for discussions. After a median follow-up of 35 months, 86 of the 102 patients had died with an observed median survival of 12 months. Oncologists' estimates of each patient's worst case, predicted and best case scenarios were well-calibrated: 10% of patients lived for fewer months than estimated for the worst 10% of similar patients; 50% lived for at least as long as estimated for 50% of similar patients (predicted survival), and 17% lived for more months than estimated for the best 10% of similar patients. Oncologists' estimates of each patient's predicted survival were imprecise: 29% were within 0.67-1.33 times the patient's actual survival, 35% were too optimistic (>1.33 times the actual survival), and 39% were too pessimistic (<0.67 times the actual survival). The proportions of patients with actual survival times bounded by simple multiples of their predicted survival were as follows: 61% between half to double their predicted, 6% at least three to four times their predicted, and 4% no more than 1/6 of their predicted; similar to the proportions in an exponential distribution (about 50%, 10% and 10% respectively). Ranges based on simple multiples of the predicted survival time appropriately convey prognosis and its uncertainty in newly referred people with incurable cancer.

Weekly docetaxel as second line treatment after mitozantrone for androgen-independent prostate cancer.

BACKGROUND: Two recent phase III trials have shown an improvement in survival with the use of docetaxel in metastatic androgen-independent prostate cancer (AIPC) compared to mitozantrone. However no phase II trials have clearly defined the level of activity of docetaxel after mitozantrone. AIMS: We sought to define the activity and toxicity of weekly docetaxel as second line chemotherapy after mitozantrone in men with AIPC. METHODS: Twenty men were treated with docetaxel 40 mg/m2 weekly for 3 of every 4 weeks until progression or prohibitive toxicity. End-points included prostate specific antigen response, common toxicity criteria, time to progression and overall survival. RESULTS: Nine patients (45%) had a 50% or greater reduction in PSA maintained for at least 1 month. Weekly docetaxel was well tolerated with few major toxicities: two patients had Grade 3 diarrhoea (10%) and six had grade 2-4 haematologic toxicities (30%). The median time to progression was 5 months (range 0-13) and median survival was 13 months (range 1-24) from starting docetaxel. The median survival from starting mitozantrone was 19 months. Men who had responded to mitozantrone were no more likely to respond to docetaxel (P = 0.2 Fischer's exact test). CONCLUSIONS: Weekly docetaxel is a safe and active second-line treatment after mitozantrone for androgen-resistant prostate cancer, with similar levels of activity to the first-line setting.

Smoking reduction does work: resulting alterations in the incidence and histological subtypes of lung cancer in New South Wales in the last 20 years.

BACKGROUND: There is irrefutable evidence of the association between lung cancer and smoking. The effects of public health campaigns to reduce population-smoking rates on the incidence and the histological distribution of lung cancer were examined. METHODS: The data held in the New South Wales Cancer Registry from 1972 to 2001 was accessed. RESULTS: The data revealed a decreasing incidence of lung cancer amongst males and a rate that continued to increase amongst females. Interestingly, there was also an effect on the histological distribution of lung cancers, with falling rates of small cell lung cancer and squamous cell cancer, both of which have a high association with smoking; and an increasing incidence of adenocarcinomas. CONCLUSIONS: These trends reveal patterns seen worldwide. The increasing proportion of adenocarcinomas in particular may be related to the changing composition of cigarettes and filters.

Docetaxel and carboplatin is an active regimen in advanced non-small-cell lung cancer: a phase II study in Caucasian and Asian patients.

BACKGROUND: The purpose of this study was to report response rates, survival and toxicity in advanced non-small-cell lung cancer (NSCLC) following docetaxel and carboplatin, and to explore potential differences in these end points between Caucasian and Asian patients. PATIENTS AND METHODS: Sixty-eight patients of good performance status with Stage IIIB or IV NSCLC were entered on a phase II study at three sites in Australia and Singapore. Docetaxel 75 mg/m2 and carboplatin AUC 6 were given every 3 weeks. Response to treatment and toxicity were graded by standard criteria. The Kaplan-Meier method was used to estimate survival rates, and subgroups compared by the log-rank test. Cox's proportional hazards regression was used to determine which potentially explanatory variables independently affected the outcome. RESULTS: The response rate was 39% (95% confidence interval 27% to 52%), and 42% in evaluable patients. Response occurred in 65% of Asian and 31% of Caucasian patients (P = 0.01). Ethnicity was the only significant predictor of response in multivariate analysis. The 1-year survival rate was 53%. Performance status (P = 0.021), ethnicity (P = 0.035) and presence of bone or liver metastases (P = 0.011) were independent predictors of overall survival. Neutropenia (grade IV in 73% of patients), febrile neutropenia (26% patients) and diarrhea (grade III/IV in 11% of patients) were the major treatment related toxicities. A high rate (three of six) of febrile neutropenia in Singapore, including one treatment-related death in the initial patients treated, resulted in a reduction in the carboplatin dose to AUC 4.5 at that site. CONCLUSIONS: This regimen is active in advanced NSCLC. The potential impact of ethnicity on efficacy and toxicity of treatment requires further investigation.

Phase II trial of pemetrexed disodium (ALIMTA, LY231514) in chemotherapy-naïve patients with advanced non-small-cell lung cancer.

BACKGROUND: To evaluate the efficacy and safety of pemetrexed therapy for chemotherapy-naïve patients with surgically incurable non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS: Eligible patients received pemetrexed 600 mg/m2 every 3 weeks. Restaging was performed after every two cycles of therapy and toxicity was assessed at each cycle of pemetrexed. In the absence of disease progression or undue toxicity, treatment was continued for a maximum of 12 cycles. RESULTS: Fifty-nine patients (median age 59 years; range 39-74 years) received a median of four cycles of pemetrexed. Nineteen patients (32%) had a ECOG performance status (PS) of two and 39 patients (66%) had stage IV disease. The most common histological sub-types were adenocarcinoma (20 patients, 34%) and large cell (18 patients, 31%). Sixteen patients (27%) had received prior radiotherapy. Nine patients achieved a partial response for an overall response rate of 15.8% (95% confidence interval CI 7% to 28%). The median duration of response was 4.9 months, and the median survival was 7.2 months. The principal toxicities were myelosuppression and rash. While grade 3 or 4 neutropenia was seen in 25 patients (42%), only two patients (3%) developed grade 3 infection. Eighteen patients (31%) developed grade 3 or 4 cutaneous toxicity, which improved with prophylactic oral dexamethasone administered for 3 days beginning the day before pemetrexed treatment. Asymptomatic elevations in hepatic biochemistry (especially alanine transaminase and aspartate transaminase) were seen in 47 patients (80%); however, these did not interfere with the dose or schedule of pemetrexed and returned to normal levels throughout the study. CONCLUSIONS: This is the largest study confirming the encouraging single-agent activity of pemetrexed in chemotherapy-naïve patients with NSCLC. In addition, this study demonstrates that a dose of 600 mg/m2 can be delivered safely; however, treatment should be restricted to patients with a PS of 0 or 1. The results of combination studies are awaited with interest.

Resection of residual pulmonary masses after chemotherapy in patients with metastatic non-seminomatous germ cell tumours.

BACKGROUND: Resection of residual post-chemotherapy pulmonary masses in patients with non-seminomatous germ cell tumours gives therapeutic benefit and prognostic information. AIM: This study was undertaken to review the experience of this intervention in a single teaching hospital. METHODS: The Germ Cell Database of the Sydney Cancer Centre was searched for all patients who had undergone excision of pulmonary metastases. These patient records were subsequently reviewed. RESULTS: Between 1976 and 1999, 15 patients underwent a combined total of 19 thoracotomies for resection of residual tumour mass after cisplatin-based chemotherapy. The primary tumour histology included mature teratoma in 47% (7 of 15) of patients. Prior to chemotherapy, 73% (11 of 15) of patients had elevated serum levels of alpha-fetoprotein (median 180 ng/mL) and 60% (9 of 15) of patients had elevated beta-human chorionic gonadotropin (median 672 IU/L). The median length of hospital stay related to thoracotomy was 7 days. There were two surgical complications, a prolonged air leak and a residual pleural effusion. Pathology of residual pulmonary masses revealed necrosis alone in 37% (7 of 19) of procedures, mature teratoma alone in 32% (6 of 19) of procedures and viable tumour in 32% (6 of 19) of procedures. Of those with viable tumour, three achieved long-term complete response (CR), two died of progressive disease (PD) and one is alive with PD. Of those with teratoma, two achieved CR and one relapsed. The long-term CR rate was 80% (12 of 15 patients). The median follow up was 10 years (range 0.75-17.5 years). Four patients died, two of PD and two of cardiovascular disease while in CR. CONCLUSION: At this institution, thoracotomy for residual pulmonary masses was well tolerated, with a high cure rate.

Phase II study of paclitaxel and oral etoposide in patients with locally advanced or metastatic non-small cell lung cancer.

The combination of paclitaxel and etoposide was evaluated in a phase II study in patients with locally advanced or metastatic non small-cell lung cancer (NSCLC). Thirty-five patients, median age 61, received treatment with paclitaxel 200 mg/m (2) intravenous over 3 h on day 1, and oral etoposide, 100 mg daily on days 1-5. Cycles were repeated every 21 days for a maximum of nine cycles, or until progression occurred. Twenty-eight patients had stage IV disease, and seven patients had stage IIIA or B disease. There was one complete and seven partial responses (overall response rate, 23%). Two of these responses were in patients with stage III disease (29%) and six in patients with stage IV disease (21%). Median survival was 8.7 months, and 36% of patients were alive at 1 year. There were no treatment-related deaths and little grade 3 or 4 non-haematological toxicity although grade 3 or 4 neutropenia occurred in 60% of patients (33% of cycles). There were four episodes of febrile neutropenia. The combination of paclitaxel and oral etoposide is active in advanced NSCLC and can be delivered with acceptable toxicity.

Comparison of two standard chemotherapy regimens for good-prognosis germ-cell tumours: a randomised trial. Australian and New Zealand Germ Cell Trial Group.

BACKGROUND: Most patients with metastatic germ-cell tumours are cured with chemotherapy. However, the optimum chemotherapy regimen is uncertain, and there is variation in international practice. We did a multicentre randomised trial to compare two standard chemotherapy regimens for men with good-prognosis germ-cell tumours. METHODS: Good prognosis was defined by modified Memorial Sloan-Kettering criteria. The first regimen (regimen A) was based on treatment recommendations from Indiana University and comprised three cycles of 20 mg/m2 cisplatin on days 1-5, 100 mg/m2 etoposide on days 1-5, and 30 kU bleomycin on days 1, 8, and 15, repeated every 21 days. The second regimen (regimen B) was based on the control regimen of a published randomised clinical trial and comprised four cycles of 100 mg/m2 cisplatin on day 1, 120 mg/m2 etoposide on days 1-3, and 30 kU bleomycin on day 1, repeated every 21 days. The primary outcome measure was overall survival. Analysis was by intention to treat. FINDINGS: 166 patients were randomised, 83 to each regimen. The trial was stopped when the second planned interim analysis met predefined stopping rules. The median follow-up was 33 months. Overall survival was substantially better with regimen A (three vs 13 deaths, hazard ratio 0.22 [95% CI 0.06-0.77], p=0.008). This difference was due to deaths from cancer (one vs nine), and not deaths from treatment (two vs two) and remained significant after adjustment for other prognostic factors (0.25 [0.07-0.88], p=0.03). INTERPRETATION: In men with good-prognosis germ-cell tumours, the regimen developed at Indiana University is superior to the alternative regimen studied in this trial. The lower total dose and dose-intensity of bleomycin and the lower dose-intensity of etoposide in regimen B could be responsible for the worse outcome.
