Survey on the treatment of non-small cell lung cancer (NSCLC) in England and Wales.

As an adjunct to a meta-analysis of chemotherapy for non-small cell lung cancer (NSCLC), a survey was conducted in England and Wales of clinicians' views on the role of chemotherapy in NSCLC and the benefits it would have to offer to lead them to change their practice. Radiotherapists, medical oncologists, surgeons and physicians specializing in thoracic medicine, and physicians of palliative medicine were asked their views on the treatment of three case histories of 65 yr old men: Case 1, resected tumour involving a hilar lymph node (tumour (T)2, node (N)1, metastasis (M)0); Case 2, tumour that had spread to mediastinal lymph nodes bilaterally (T2, N3, M0); and Case 3, metastatic cancer (M1) accompanied by minor haemoptysis. Six hundred and ninety eight (85%) of the 821 clinicians responded. For Case 1, 74% would not recommend any adjuvant treatment, 24% would recommend radiotherapy, and <1% chemotherapy, and there was little expectation that adjuvant treatment would improve survival. For Case 2, 68% would recommend radiotherapy, 11% chemotherapy, and 1% surgery, 7% recommending a combination. Adjuvant treatment, regardless of modality, was expected to improve survival. For Case 3, only 11% would recommend chemotherapy, but 26% if the patient was aged < or = 50 yrs. There was little expectation of survival beyond 1 yr, or of improving survival with chemotherapy. For all three cases, most of those not recommending chemotherapy would require it to achieve substantially improved survival for them to use it routinely. Surgery alone is currently considered sufficient for resectable non-small cell lung cancer. Chemotherapy is rarely recommended for disease of any stage.

Comparison of oral etoposide and standard intravenous multidrug chemotherapy for small-cell lung cancer: a stopped multicentre randomised trial. Medical Research Council Lung Cancer Working Party.

BACKGROUND: Single-drug oral etoposide daily for 5 days or more in 3-week cycles is commonly used as palliative chemotherapy for small-cell lung cancer (SCLC). However, there have been no randomised trials to compare this treatment with standard intravenous multidrug chemotherapy. Our objective was such a comparison in patients with poor performance status. However, before the planned intake of 450 patients had been completed the trial was stopped on the recommendation of an independent data monitoring committee, because of the inferiority of oral etoposide. We report the interim findings of the trial. METHODS: Patients of either sex and any age were entered into the trial if they had: previously untreated, microscopically confirmed SCLC; WHO grade performance status 2-4; no contraindications to either treatment regimen; normal renal function; and plasma bilirubin concentrations of less than 35 mumol/L. Patients with grade 4 performance status were likely to benefit from chemotherapy. Between September, 1992, and August, 1995, 339 patients were randomly allocated four cycles of 50 mg oral etoposide twice daily for 10 days (171 patients) or a standard intravenous regimen of etoposide and vincristine (EV), or cyclophosphamide, doxorubicin, and vincristine (CAV, 168 controls). The intake was stopped in September, 1995. Patients were assessed by clinicians before the start of treatment, at each attendance for treatment, at 3 months after randomisation, every month to 6 months, every 2 months to 1 year, then every 3 months thereafter. The primary endpoint was the palliation of major symptoms at 3 months after randomisation-ie, a reduction in cough, pain, anorexia, and shortness of breath scores. Secondary endpoints were quality of life, clinical and radiographic tumour response, and survival. FINDINGS: The palliative effects of treatment were similar in the etoposide group and control group (41% vs 46%). Grade 2 or worse haematological toxicity occurred in 35 (29%) etoposide-treated patients and 26 (21%) controls. Controls had a higher overall response rate than etoposide-treated patients (51% vs 45%). There was a small disadvantage in survival associated with oral etoposide (hazard ratio 1.35 [95% CI 1.03-1.79], p = 0.03). Median survival was 130 days in the etoposide group and 183 days in the controls; survival rates were 35% and 49% at 6 months and 11% and 13% at 12 months, respectively. INTERPRETATION: Oral etoposide 50 mg twice daily for 10 days every 3 weeks for four cycles is inferior to standard intravenous multidrug chemotherapy in the palliative treatment of patients with SCLC and poor performance status. Oral etoposide alone should no longer be used in the treatment of such patients.

Randomized trial of palliative two-fraction versus more intensive 13-fraction radiotherapy for patients with inoperable non-small cell lung cancer and good performance status. Medical Research Council Lung Cancer Working Party.

In patients with non-metastatic but inoperable non-small cell lung cancer that is locally too extensive for radical radiotherapy (RT), but who have good performance status, it is important to determine whether thoracic RT should be the minimum that is required to palliate thoracic symptoms or whether treatment should be more intensive, with the aim of prolonging survival. A total of 509 such patients from 11 centres in the UK between November 1989 and October 1992 were admitted to a trial comparing palliative versus more intensive RT with respect to survival and quality of life. They were allocated at random to receive thoracic RT with either 17 Gy in two fractions (F2) 1 week apart (255 patients) or 39 Gy in 13 fractions (F13) 5 days per week (254 patients). Survival was better in the F13 group, the median survival periods being 7 months in the F2 group compared with 9 months in the F13 group, and the survival rates 31% and 36% at one year and 9% and 12% at 2 years, respectively (hazard ratio = 0.82; 95% CI0.69-0.99). There was a suggestion of a trend towards greater benefit in fitter patients. Metastases appeared earlier in the F2 group. As recorded by patients using the Rotterdam Symptom Checklist, the commonest symptoms on admission were cough, shortness of breath, tiredness, lack of energy, worrying and chest pain. These were more rapidly palliated by the F2 regimen. Psychological distress was generally lower in the F13 group. Three patients (two F13, one F2) exhibited evidence of myelopathy. As recorded by patients using a diary card, 76% of the F2 compared with 81% of the F13 patients had dysphagia associated with their RT. This was transient, lasting for a median of 6.5 days in the F2 group compared with 14 days in the F13 group. In conclusion, the F2 regimen had a more rapid palliative effect. In the F13 group, although treatment-related dysphagia was worse, survival was longer.

Radiation myelopathy: estimates of risk in 1048 patients in three randomized trials of palliative radiotherapy for non-small cell lung cancer. The Medical Research Council Lung Cancer Working Party.

Radiation myelopathy (RM) is an uncommon but serious late effect of thoracic radiotherapy (RT), which oncologists try to avoid by careful planning and dose selection. Five patients with RM are described from among 1048 with inoperable non-small cell lung cancer treated with palliative RT in three randomized trials conducted by the Medical Research Council Lung Cancer Working Party. Seven RT regimens were used in these trials: 10 Gy in a single fraction on one day (10/1/1) (114 patients), 17/2/8 (524 patients), 27/6/11 (47 patients), 30/6/11 (36 patients), 30/10/12 (88 patients), 36/12/16 (86 patients) and 39/13/17 (153 patients). Of the five instances of RM, three occurred in the 524 patients treated with 17 Gy in two fractions, and two in the 153 treated with 39 Gy in 13 fractions. The estimated cumulative risks of RM by 2 years were 2.2% for the 17 Gy group, 2.5% for the 39 Gy group, and 0% for the remainder, but the annual risks had wide 95% confidence intervals, indicating that the distribution of episodes among the seven regimens could have been random. Nevertheless, calculation of cord doses in terms of the total doses that would have an equivalent biological effect if given in 2 Gy fractions (LQED2 values) from our data for different values of the ratio of the linear quadratic parameters of the cell survival curve (alpha/beta), suggest that the best estimate of alpha/beta is less than 3 Gy, and possibly close to 2 Gy. This emphasizes the sensitivity of human spinal cord to changes in fraction size. We recommend that, when the computed LQED2 for a schedule of treatment that includes the thoracic spinal cord (assuming alpha/beta = 2 for cord) exceeds 48 Gy, oncologists should consider reducing the dose to the cord.

The role of post-operative radiotherapy in non-small-cell lung cancer: a multicentre randomised trial in patients with pathologically staged T1-2, N1-2, M0 disease. Medical Research Council Lung Cancer Working Party.

The role of post-operative radiotherapy for patients with non-small-cell lung cancer (NSCLC) is unclear despite five previous randomised trials. One deficiency with these trials was that they did not include adequate TNM staging, and so the present randomised trial was designed to compare surgery alone (S) with surgery plus post-operative radiotherapy (SR) in patients with pathologically staged T1-2, N1-2. M0 NSCLC. Between July 1986 and October 1993, 308 patients (154 S, 154 SR) were entered from 16 centres in the UK. The median age of the patients was 62 years, 74% were male, > 85% had normal or near normal levels of general condition, activity and breathlessness, 68% had squamous carcinoma, 52% had had a pneumonectomy, 63% had N1 disease and 37% N2 disease. SR patients received 40 Gy in 15 fractions starting 4-6 weeks post-operatively. Overall there was no advantage to either group in terms of survival, although definite local recurrence and bony metastases appeared less frequently and later in the SR group. In a subgroup analysis, in the N1 group no differences between the treatment groups were seen, but in the N2 group SR patients appeared to gain a one month survival advantage, delayed time to local recurrence and time to appearance of the bone metastases. There is, therefore, no clear indication for post-operative radiotherapy in N1 disease, but the question remains unresolved in N2 disease.

The feasibility of using glycosylated recombinant human granulocyte colony-stimulating factor (G-CSF) to increase the planned dose intensity of doxorubicin, cyclophosphamide and etoposide (ACE) in the treatment of small cell lung cancer. Medical Research Council Lung Cancer Working Party.

This study was conducted to test the feasibility of reducing the interval between cycles of doxorubicin, cyclophosphamide, etoposide (ACE) chemotherapy to 2 weeks, thereby increasing dose intensity, by adding granulocyte colony-stimulating factor (G-CSF) to reduce the duration of neutropenia following a cycle. 20 patients with small cell lung cancer (SCLC) were prescribed six cycles of 2-weekly ACE, with G-CSF on the intermediate days. 3 patients died during the treatment period and a further 5 had ACE terminated, 3 for toxicity and 2 for progressive disease. Of the 71 intervals between cycles, 42 (59%) were of the prescribed 14 days, 9 (13%) of 15-20 days, 15 (21%) of 21 days and five (7%) longer, but during the first four cycles, 36 (77%) of 47 intervals were of 14 days. The main reason for delay was haematological toxicity. All 20 patients experienced WHO grade 3 or 4 neutropenia, but at 2 weeks after a cycle only 3 had grade 4 and 1 grade 3. 17 patients required blood transfusion and 12 platelet transfusion. The only potentially serious adverse reaction to G-CSF was an episode of rash with facial oedema. Adding G-CSF allows ACE chemotherapy to be intensified by reducing the interval between cycles.

Increasing and planned dose intensity of doxorubicin, cyclophosphamide and etoposide (ACE) by adding recombinant human methionyl granulocyte colony-stimulating factor (G-CSF; filgrastim) in the treatment of small cell lung cancer (SCLC). Medical Research Council Lung Cancer Working Party.

The aim of this Phase II study was to test the feasibility of intensifying standard chemotherapy in the treatment of small cell lung cancer (SCLC) by reducing the interval between cycles from 3 to 2 weeks by adding recombinant human methionyl granulocyte colony-stimulating factor (G-CSF; filgrastim) to shorten the duration of neutropenia following each cycle. Thirty-two patients with SCLC were prescribed six cycles of 2-weekly doxorubicin 50 mg/m2 and cyclophosphamide 1 g/m2 on day 1, and etoposide 120 mg/m2 i.v. on days 1, 2 and 3 (ACE), plus filgrastim in a fixed dose of 300 micrograms s.c. on days 4-14 of each cycle. Three patients died during the treatment period and a further nine had chemotherapy terminated before the sixth cycle, all nine because of toxicity. All 32 patients have been followed up for at least 21 months; 14 (44%) were alive at 12 months and the median survival period was 356 days. Of the 127 intervals between cycles of chemotherapy, 74 (58%) were of the prescribed 14 days, 18 (14%) of 15-20 days, 25 (20%) of 21 days, and 10 (8%) were longer. The results were best during the first four cycles, during which 71% of the 83 intervals were of 14 days and a further 10% were less than 21 days. The main reason for delay was haematological toxicity in 37 of the 53 instances. Symptoms of myelosuppression occurred in 23 patients, but at 14 days after a cycle of chemotherapy, all 127 available neutrophil granulocyte counts were normal. Twenty-one patients received blood transfusion and five platelet transfusion. The only adverse effects attributed to filgastrim were episodes of rash, throat swelling, anorexia and shivering, affecting one patient. We conclude that the policy of adding filgrastim allows the dose intensity of ACE chemotherapy to be increased by reducing the intervals between cycles. The findings reinforce those of a parallel study involving lenograstim.

Treatment-related deaths in small cell lung cancer trials: can patients at risk be identified? Medical Research Council Lung Cancer Working Party.

OBJECTIVES: This paper investigates the problem of treatment-related deaths in small cell lung cancer (SCLC). DESIGN: To observe and define increased hazard levels, and to identify factors relating to these excess deaths. SETTING: The United Kingdom. SUBJECTS: A total of 2196 patients entered into the series of six randomised clinical trials in SCLC conducted by the Medical Research Council (MRC) Lung Cancer Working Party (LCWP). RESULTS: In this large series of patients an increased risk of death in the second week after commencing the first cycle of chemotherapy was observed, suggesting that of the 10% of patients who died within 3 weeks of starting chemotherapy, half may have been treatment-related. Much less additional risk was associated with subsequent cycles of chemotherapy, and no additional risk with either initial surgery or radiotherapy. Radford et al. [Eur J Cancer 1993; 29A: 81-86] suggested that the risk factors for death from sepsis were a Karnofsky Performance (KP) score of < or = 50 (translated as a WHO performance grade (PS) > or = 3), age > 50 years and three or more drugs in the chemotherapy regimen utilised. Starting with this model we found that our data suggest it can be refined by omitting age and including a white blood cell count > or = 10,000/mm3 (this variable was not tested by Radford), and changing the other categories to WHO PS > or = 2 (KP < or = 70), and four or more drugs. Within our data this revised model identified a high risk group of patients with an excess death rate of more than 15% in the second week after starting chemotherapy. Radford et als' suggestion that high risk patients be given half doses of drugs at the first cycle should be tested in a randomised clinical trial.

Does clinical experience with a treatment regimen affect survival of lung cancer patients? An analysis based on consecutive randomized trials of the Medical Research Council in small cell and non-small cell tumours. Medical Research Council Lung Cancer Working Party.

This paper investigates the influence on patient survival of an individual clinician's experience with a particular treatment regimen and the collective experience of the centre through which the patient is recruited to a particular clinical trial. Data were available from two series of randomized trials, one series in small cell and the other in non-small cell lung cancer, which were conducted by the Medical Research Council Lung Cancer Working Party. Successive small cell trials used the same chemotherapy regimen and successive non-small cell trials the same radiotherapy regimen. We found no evidence that either the degree of experience of individual clinicians with the regimen or the participation in terms of number of patients recruited to centres influenced patient survival. There is a strong suggestion, in non-small cell lung cancer that, as clinicians' experience with the regimen extended, they became increasingly likely to admit patients in poor condition to the trials. We stress how important it is to take account of patient prognostic characteristics in such an analysis, as we found that unadjusted comparisons suggested negative influences of increasing experience with the regimen. The implications for routine audit are self evident, in particular that it is not a substitute for the randomized controlled trial.

Can long-term survival be improved in patients with small-cell lung cancer (SCLC) and good performance status? Medical Research Council Lung Cancer Working Party.

Results from a long-term follow-up suggest that in patients with limited small-cell lung cancer (SCLC) and normal performance status intensive alternating chemotherapy and radiotherapy improve long-term survival rates. In a non-randomised study, 22 patients with SCLC of limited extent and good performance status were prescribed six cycles of etoposide, doxorubicin, cisplatin and cyclophosphamide at 4 week intervals with doses of thoracic radiotherapy following the second, third and fourth cycles. Although only six patients received all their prescribed treatment, nine (41%) were alive at 1 year, seven (32%) at 2 years, six (27%) at 3 years, and four are still alive at, respectively, 42, 47, 50, and 61 months, all four being in the subgroup of eight patients with WHO performance status grade 0 at the start of treatment. In a comparison with similar patients receiving conventionally scheduled chemotherapy and radiotherapy in a concurrent trial, no difference in survival was seen in the patients with performance status grade 1 or 2, but a large difference in favour of the alternating schedule in those with grade 0 status was seen. We encourage other investigators to report the results achieved with intensive treatment in patients with WHO grade 0 performance status at the start of treatment.

A randomised trial of three or six courses of etoposide cyclophosphamide methotrexate and vincristine or six courses of etoposide and ifosfamide in small cell lung cancer (SCLC). I: Survival and prognostic factors. Medical Research Council Lung Cancer Working Party.

A total of 458 eligible patients, from 21 centres, with histologically or cytologically confirmed SCLC were allocated at random to three chemotherapy regimens, each given at 3-week intervals. In two regimens, etoposide, cyclophosphamide, methotrexate and vincristine were given for a total of either three courses (ECMV3) or six courses (ECMV6). In the third regimen, etoposide and ifosfamide were given for six courses (EI6). Patients with limited disease (56% of the total) also received radiotherapy to the primary site after the third course of chemotherapy in all three groups. A partial response occurred in 45% of 144 ECMV3 patients, 48% of 141 ECMV6, and 53% of 141 EI6 patients assessed, and a complete response in a further 15%, 9%, and 13% respectively, giving total response rates of 60%, 57%, and 67%, respectively. There was no overall survival advantage to any of the three regimens. At 1 year, 24%, 29%, and 30% of patients were alive, and at 2 years 7%, 8%, and 9%, respectively. The median survival time was 7.4 months in the ECMV3 group, 8.6 months in the ECMV6 group and 8.8 months in the EI6 group. The individual factors: poor performance status, extensive disease, the presence of dysphagia and a raised white blood cell count on admission adversely affected prognosis. The results do not exclude the possibility of a minor survival advantage with the two 6-course regimens. The findings on quality of life are presented in the companion paper (MRC Lung Cancer Working Party, 1993b).

A randomised trial of three or six courses of etoposide cyclophosphamide methotrexate and vincristine or six courses of etoposide and ifosfamide in small cell lung cancer (SCLC). II: Quality of life. Medical Research Council Lung Cancer Working Party.

A total of 458 eligible patients, from 21 centres, with microscopically confirmed SCLC were allocated at random to three chemotherapy regimens, each given at 3-week intervals. In two regimens, etoposide, cyclophosphamide, methotrexate and vincristine were given for a total of either three courses (ECMV3) or six courses (ECMV6). In the third regimen, etoposide and ifosfamide were given for six courses (E16). Patients with limited disease also received radiotherapy to the primary site after the third course of chemotherapy in all three groups. As reported by clinicians, 59% of the ECMV3, 67% of the ECMV6 and 63% of the EI6 patients experienced moderate or severe adverse reactions to their chemotherapy. The major symptoms of disease, cough, haemoptysis, chest pain, anorexia, and dysphagia, were palliated in 63% or more of patients and the median duration of palliation was 63% or more of survival, the results being similar in the three groups. Among patients with poor overall condition, physical activity and breathlessness on admission, the proportions who improved were higher in the EI6 group but the differences were small. In all three groups, levels of anxiety fell substantially during treatment. Levels of depression were lower and showed little change. As assessed by patients using a daily diary card, the patterns of nausea, vomiting, activity and mood, associated with courses of chemotherapy were very similar in the three groups. In the EI6 group there was less dysphagia and better overall condition between courses, but these advantages need to be weighed against the inconvenience of the 24-h infusions required, compared with the 30-min infusions of the other two regimens. As reported in the companion paper (MRC Lung Cancer Working Party, 1993a) there was no statistically significant survival advantage to any of the three regimens, although the results do not exclude the possibility of a minor survival advantage with the two six-course regimens. In conclusion, there was no major clinical gain from continuing chemotherapy beyond three courses or from using the ifosfamide regimen.
