A phase II clinical study of 254-S, a new anticancer platinum complex, for primary lung cancer was conducted by the 254-S Lung Cancer Study Group consisting of 15 institutions nation-wide. Considering the results of the phase I clinical study, 254-S was administered at 100 mg/m2 by intravenous drip infusion and this administration was repeated at least 2 times at 4-week intervals. Of 75 patients registered, 61 patients consisting of 22 with small cell lung cancer (SCLC) and 39 with non-small cell lung cancer (NSCLC) were evaluable for complete tumor response. Partial response (PR) was obtained in 17 patients, for a 27.9% response rate. The response rate for SCLC was 40.9% (9 PR in 22 patients) and that for NSCLC was 20.5% (8 PR in 39 patients). In SCLC patients with no prior chemotherapy, a 50.0% (5 PR in 10 patients) response rate was obtained. In those with prior chemotherapy, the response rate was 33.3% (4 PR in 12 patients). In NSCLC patients with no prior chemotherapy, a 22.6% (7 PR in 31 patients) response rate was obtained. In hose with prior chemotherapy, the response rate was 12.5% (1 PR in 8 patients). Major toxic effects observed were hematotoxicity such as thrombocytopenia and leukopenia, and gastrointestinal toxicity such as nausea, vomiting and anorexia. Nephrotoxicity observed was mild and infrequent in spite of the low-volume hydration performed. Based on these results, it was concluded that 254-S is a useful anticancer agent for the treatment of primary lung cancer.

An 86-year-old man was admitted to our hospital with complaints of dyspnea and productive cough, and diagnosed as small cell lung cancer with sputum cytology. We concluded that he was unsuitable for standard aggressive intravenous chemotherapy because of an old age, a poor performance status and cardiac complication. He was treated with oral etoposide (100 mg/day x 16.5 days), and showed a good partial response and improvement of clinical symptoms. Toxicities were leukopenia, alopecia, and anorexia. Daily oral administration of etoposide is considered to be effective and useful for elderly patient with small cell lung cancer.

Recombinant interferon A (50 x 10(6) U/m2 three times weekly) was given to 17 patients with SCCL and 13 patients with SQL. The minimal scheduled duration of therapy was 12 weeks. Fifteen and 11 patients, respectively, were evaluable for response. All 15 patients with SCCL showed progressive disease after a period of 2.5 weeks (median; range 1-13). One patient with SQL obtained a partial remission lasting 14 months and six patients showed no change for 14-20 weeks, while the remaining patients showed progression during the initial 12 week period. Toxicity was shown to be significant and only one patient completed therapy without dose reduction. The major cause of dose reduction was fatigue and anorexia (18 patients). Fourteen patients experienced a median weight loss of 6%. Haematological and hepatological toxicity was found in six and 19 patients, respectively. In most cases parameters of marrow and liver function were reversible in spite of continuing interferon treatment.

Human leukocyte interferon, HuIFN-alpha (LE), has been tested in combination with radiotherapy and chemotherapy for previously untreated small cell lung cancer. Nine patients with limited disease received high-dose IFN followed by a low-dose regimen; and six patients had a low-dose regimen from the beginning. The high dosage of IFN consisted of 800 X 10(6) IU given as a continuous intravenous infusion for 5 days, followed by 6 X 10(6) IU i.m. three times weekly. If the first site of disease progression was local or in a central nervous system location, radiotherapy (55 Gy/20 F/7 weeks locally and/or 30 Gy/10 F/2 weeks whole brain) was applied and IFN was continued. Chemotherapy was administered only if there was disease dissemination outside the chest. Three patients achieved minor response for as long as 20, 25, and 42 weeks, respectively, with IFN alone. Three of five complete responders to IFN-radiotherapy died 18, 33, and 41 weeks from the start of IFN treatment without chemotherapy. Autopsy did not reveal macroscopic or microscopic tumor at any site, but there was severe radiation pneumonitis. Four of nine patients were administered chemotherapy subsequent to IFN-radiotherapy because of disease dissemination. The median length of survival of the entire group was 41 weeks. On the low-dose regimen, one patient achieved partial response with IFN alone (duration, 12 weeks); of five evaluable patients three achieved complete remission and two partial remission to IFN-radiotherapy, and one of the three complete responders to IFN-radiotherapy died of severe radiation pneumonitis at 21 weeks from the start of IFN treatment. No tumor was detected at autopsy. The study is in progress. Average survival at present is 33 weeks. The results derived from both our studies suggest a growth-delaying effect of HuIFN-alpha (Le) on small cell lung cancer. They also suggest potentiation of radiation by HuIFN-alpha (Le). Memory and psychomotor dysfunction, fatigue, and anorexia were dose limiting with both short-duration, high-dose and long-duration, low-dose IFN therapy. We feel that IFN, as part of a combined multimodality treatment of small cell lung cancer, may play a role by delaying metastatic dissemination.

A phase II clinical trial of VP-16-213 was carried out in 71 patients with small cell and non-small cell carcinoma of the lung. Forty-eight evaluable cases consisted of 36 small cell carcinomas, 7 epidermoid carcinomas, 4 adenocarcinomas and one unclassified carcinoma. VP-16-213 was administered by drip infusion at dosages of 60-100mg/m2/day for 5-consecutive days at 3-4 week intervals. Twelve of 36 (33.3%) small cell carcinomas had partial responses, while no responses were obtained in non-small cell carcinomas. Median duration of responses was 46 days (range 31-133 days). The dose limiting toxicity was leukopenia. Median number of days to nadir was 14 days and median numbers of days for recovery was 11 days. Nausea (38%), vomiting (12%), anorexia (45%) and alopecia (74%) were major clinical toxicities although these were mild or reversible. We concluded that VP-16-213 was useful in the treatment of small cell lung cancer and the dose schedule used in this study was recommendable with small dose reduction for further trial of combination chemotherapy.

A 53-year-old man complained of anorexia and abdominal distention of one month's duration. The chest X-ray demonstrated a mass in the left lung with hilar and mediastinal adenopathy and a lytic lesion in the right fourth rib. A transbronchoscopic biopsy of the mass revealed oat cell carcinoma (WHO classification). The endoscopic evaluation also revealed a gastric lesion (IIc type). Biopsy of this lesion indicated signet ring cell gastric cancer. An abdominal CT scan demonstrated multiple liver metastases. Based on these findings, the patient was diagnosed as having synchronous lung and gastric primaries, with liver and bone metastasis from lung cancer. Carboplatin (CBDCA) was administered by intravenous drip infusion of 450 mg/m2. After a second treatment with CBDCA about 3 weeks later, the patient achieved a partial response at the primary site of lung cancer as well as at the liver and bone metastases. In addition, repeat endoscopy of the stomach demonstrated a complete regression. A biopsy specimen taken by gastroscopy was negative for cancer cells. Subsequent chemotherapy for small cell lung cancer was administered with cyclophosphamide, adriamycin, and vincristine, and to date there is no evidence of recurrence. Further studies on CBDCA treatment of small cell lung cancer and gastric cancer are needed to establish the efficacy of this drug against these two histologically different cancers.

This retrospective study deals with 168 patients with small cell lung cancer (SCLC) who were treated at the NCI March 1973 and July 1977 with intensive chemotherapy. Results showed that 12 per cent of all the patients were disease-free for more than 40 months (25% of the limited disease and 3% of the extended stage disease patients which were treated. Complete remission was essential to prolonged survival. The development of a complete remission was favored by a satisfactory initial general condition, localised disease or presence of only one site of metastatic disease. Initial treatment included the following combinations: cyclophosphamide, methotrexate and CCNU. High doses are necessary. However, above a certain level, the toxicity increased without a corresponding increment in activity. Addition of another association without cross-resistance (vincristine-adriamycine-natulan or VP-16 and isophosphamide) may induce a complete remission in cases where only a partial remission was obtained initially. In limited disease, radiotherapy seemed to prolong disease-free survival. This lead the authors to study the use of initial radiotherapy, at the rate of 40 grays in 3 weeks in 15 fractions, at the same time as chemotherapy. The radiotherapist must take certain precautions in the use of this double treatment: reshaped fields and insertion of a spinal cord block above 2 000 rads. In extended disease, thoracic irradiation seemed to be of no benefit. Pilot studies are not underway using intensive chemotherapy with multiple tumor site irradiation and autologous marrow implants 48 per cent of all patients with SCLC will develop cerebral metastatic disease (44% intracranial, 13% leptomeningeal, 9% epidural). At 30 months, 75 percent of those who did not receive prophylactic irradiation developed cerebral disease whereas only 40 per cent of the patients who received a prophylactic dose of 30 grays developed cerebral disease. Inspite of the indisputable but incomplete local benefit of prophylactic brain irradiation, it did not prolong survival. Important biological studies are underway at the NCI. - Cell clone cultures have been established. These were enhanced by the addition of arginine vasopressive (AVP) and bombesine. These two substances may be considered as markers of APUD system and are secreted by the SCLC. Bombesine has been isolated in all the cultures tested. This possible marker was perhaps responsible for the anorexia and cachexia in these patients. - These cultures have allowed for identification of deletion 3p (14-23) chromosome anomalies in all the samples examined. - In vitro chemotherapy studies of these cultures have been carried out. Their correlation with clinical results were encouraging (100% negative p/n; 75% positive p/n). - Lastly, monoclonal AC have been prepared. Inspite of their imperfect specificity and heterogeneity with regard to tumor cells, their potential advantages were considerable.

Ten patients with small cell lung cancer were treated with high dose human lymphoblastoid interferon (50-100 megaunits m-2) for 5 days, followed by low dose interferon (3 megaunits m-2) for 3 weeks. At the end of treatment, and one month later, there was no evidence of either complete or partial response. The treatment produced fever, anorexia and weight loss, with transient leucopenia and thrombocytopenia; there was evidence of a non-cholestatic elevation of serum alanine aminotransferase, with clinical deterioration in the condition of three patients presenting with hyponatraemia. A transient hypocalcaemia during high dose therapy was also noted. It seems that lymphoblastoid interferon as a single agent is unlikely to have a role in the treatment of small cell lung cancer, and that its administration as employed in this study is associated with considerable toxicity.

Changes in energy metabolism, substrate use, and hormone profiles were prospectively studied in 31 patients with small cell lung cancer receiving chemotherapy. Patients were randomized to receive either 4 weeks of total parenteral nutrition (n = 15) or to continue self-regulated p.o. diet (control group; n = 16). The initial actual resting energy expenditure measured by indirect calorimetry was 31% higher than the predicted resting energy expenditure determined by the Harris-Benedict formula. The p.o. calorie intake was inappropriately low for these hypermetabolic patients. Total parenteral nutrition resulted in a significant positive net energy balance, but in follow-up was associated with prolonged anorexia and a negative energy balance. Complete response to therapy reduced resting energy expenditure and increased calorie intake, whereas the contrary was true in nonresponders. Elevated plasma-free fatty acids (800 +/- 62 microM; S.E.) and a low respiratory quotient (0.74 +/- 0.02) indicate that the dominant energy source in patients with small cell lung cancer is fat, and that increased fat oxidation continues despite tumor response. Elevated fasting plasma catecholamines and insulin resistance may contribute to continued fat mobilization. Initially, there was a significant increase in blood lactate (1118 +/- 95 microM) suggesting either increased tumor or tumor-mediated glycolytic activity. Response to therapy was associated with a fall in blood lactate levels. The most effective way of improving the metabolic derangements in patients with small cell lung cancer was to achieve tumor response to therapy.

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.
