In 1979 we initiated a phase III study in the Southwest Oncology Group (SWOG) which was designed to determine the value of chest radiation in limited-stage small-cell lung cancer patients achieving complete response after induction chemotherapy, and to test the use of wide-field v more limited-volume radiation in patients with partial responses (PRs) and patients with stable disease (SD). The induction chemotherapy (VMV-VAC) consisted of vincristine, 2 mg intravenously (IV) every week for six doses; methotrexate, 60 mg/m2 IV days 1 and 43; VP-16, 50 mg/m2/d IV days 1 to 5 and 43 to 47; doxorubicin, 60 mg/m2 IV days 22 and 64; and cyclophosphamide, 1,000 mg/m2 IV days 22 and 64. Four hundred ninety-four patients were registered, of whom 473 were eligible. Of 466 response-evaluable patients, 153 (33%) achieved complete disease remission (CR) with chemotherapy. A total of 387 patients entered the consolidation phase of treatment after chemotherapy and response determination. CR patients were prospectively randomized to receive chest radiation, consisting of 4,800 rad administered in a split-course scheme, or to continue chemotherapy without interruption. The treatment volume was based on tumor extent before the induction chemotherapy. Maintenance chemotherapy consisted of cyclophosphamide and VP-16 administered for four cycles before a period of reinduction chemotherapy consisting of VMV-VAC as described above. Patients receiving chest radiation therapy were given the same maintenance and reinduction chemotherapy programs following completion of the chest radiation. One hundred ninety-one eligible patients achieving PR or SD status after induction chemotherapy were randomized to a preinduction treatment volume or to a postinduction reduced tumor volume, with treatment portals designed according to tumor extent before or after induction chemotherapy, respectively. After completion of the entire treatment plan, there were 218 (47%) CRs and 121 (26%) PRs. These figures represent the greatest response achieved at any point in the treatment program. The median survival for all eligible patients was 57 weeks (74 weeks for CRs). Overall survival for CR patients was not different for patients who did or did not receive chest radiation. However, patterns of tumor relapse were affected by the chest radiation, as 38 of 42 relapsing patients who did not receive radiation had intrathoracic recurrences in comparison to only 20 of 36 radiated patients.(ABSTRACT TRUNCATED AT 400 WORDS)

Forty-four previously untreated patients with advanced non-small-cell lung cancer were treated in a randomized trial comparing platinum (60 mg/m2), doxorubicin (40 mg/m2), and VP-16 (150 mg/m2) (PAV) with platinum (60 mg/m2), 4'-epidoxorubicin (50 mg/m2), and VP-16 (150 mg/m2) (PEV). The overall response rate was 10%. Major response rates were quite similar for the 21 patients treated with PAV (5%) and the 23 patients treated with PEV (18%) (p = 0.2). Of the 23 patients with assigned to PEV, two (9%) achieved complete responses for a median duration of 20 weeks and 44+ weeks. There was no significant difference (p = 0.75) in the median survival among patients treated with PAV (24 weeks) and those treated with PEV (20 weeks). Toxicity was generally mild and tolerable. The lack of response found in both arms of treatment caused the study to be terminated early. Some benefit could be appreciated in patients with limited disease and good Karnofsky performance status.

In a previous study on the antiemetic effect of nabilone (N) in patients with lung cancer receiving chemotherapy (CT), we found that N was only moderately effective and that its side effects limited its use, especially in elderly outpatients. We, therefore, performed a new study of N in combination with dexamethasone (DXM), a potent antiemetic in itself, to evaluate whether the addition of DXM to N would improve the antiemetic effect and/or reduce the side effects. Forty patients with lung cancer were enrolled in the study. A randomized, third-party-blinded, crossover design was used. Study drugs were given during two consecutive, identical CT cycles. N was given at a fixed dosage regimen of 2 mg b.i.d. The initial dose was administered the evening before CT, the second dose at 0.5 h before CT, and the third dose in the evening 12 h after CT. DXM, 8 mg, or placebo was given orally with the first dose of N. The subsequent doses (either 10 mg DXM or saline) were given intravenously 0.5 h before CT and at 2 and 6 h after the start of CT. The CT regimens given included the following drugs in various combinations: cisplatin, cyclophosphamide, adriamycin, etoposide (VP-16), vincristine, and vindesine. The combination of N and DXM was significantly superior to N alone in the reduction of vomiting episodes, both in subgroups of patients receiving cisplatin and in those receiving other CT combinations. There was no statistically significant difference between the treatments with regard to the patients' assessments of the severity of nausea or effects on appetite. Approximately half the patients (63% with N plus DXM versus 47% with N) reported no side effects. The frequency and severity of central nervous system adverse reactions, mainly vertigo, were similar in both treatment groups. The fall in blood pressure was significantly greater after N alone. Two thirds of the patients preferred N plus DXM. Thus, the addition of DXM to N enhanced the therapeutic yield of N, and we recommend DXM as an adjunct to N, when the use of steroids is not contraindicated. The optimal dose and schedule of DXM was not investigated in our study; a higher dose of DXM might increase the clinical benefit of the drug combination tested.

In order to assess the effect of scheduling of chemotherapy on the outcome of patients with limited small-cell lung cancer (SCLC), the Clinical Trials Group of the National Cancer Institute of Canada carried out a randomized trial comparing the alternation of cyclophosphamide, Adriamycin (Adria Laboratories, Columbus, OH; doxorubicin) and vincristine (CAV) with etoposide (VP-16) and cisplatin for six cycles to the administration of these two combinations in a sequential fashion (three cycles of CAV followed by three of VP-16/cisplatin). Three hundred eligible patients were enrolled on the trial from September 1981 to October 1984. All responding patients were also treated after completion of chemotherapy with thoracic irradiation in randomly allocated doses of 2,000 and 3,750 cGy. The complete response (CR) rate to chemotherapy was slightly, but not significantly, higher on the alternating arm (52% v 44%, P = .20). However, there was no difference in disease-free or overall survival on the alternating and sequential arms, respectively (47.3 weeks v 45.1 weeks, P = .26; 61.7 weeks v 59.5 weeks, P = .56). Data on the effect of radiotherapy dose on survival are not yet mature, but it does not appear the results of this portion of the trial will alter the interpretation of the chemotherapy comparison. Patient characteristics favorably influencing survival were female sex, good performance status, younger age, and absence of supraclavicular node involvement. Two interpretations of these and other results in SCLC are suggested: (1) the difference between the schedules used is too small for the predictions of the Goldie-Coldman model to be realized in a trial of this size, or (2) VP-16/cisplatin is actually a superior regimen and any schedule that exposes patients to these drugs early in treatment will produce improved results.

Cisplatin (Platinol)-containing regimens, especially in combination with etoposide (VP-16) (VePesid), vindesine, and/or mitomycin-C, have proven beneficial to patients with non-small-cell lung cancer. A reproducible response rate of 30% to 40% has been achieved. Because current therapies are greatly in need of improvement, patients with non-small-cell lung cancer--especially those who have a good performance status and thus are more likely to respond--should be considered for participation in clinical studies in which the control regimens are associated with moderate response rates. Although chemotherapy affords some benefit to nonresponding patients, they might participate in phase I or phase II trials rather than continue treatment more likely to be toxic than beneficial.

The EORTC Lung Cancer Working Party investigated the effects of combination therapy with VP-16 (Ve-Pesid) and cisplatin in the treatment of non-small-cell lung cancer (NSCLC). Neither agent alone is recognized as being associated with a high rate of response in NSCLC, but the combination proved beneficial in our hands and effected a total response rate (including complete and partial responses) of over 40%. In addition to this encouraging result, complete remissions occurred in a modest number of patients. The addition of vindesine to the regimen profferred no benefit, but did increase the incidence of toxic reactions. Preliminary data on supraconventional dosages of cisplatin indicate a trend toward better response and longer survival but a significantly higher frequency of severe leukopenia as well. No studies have yet been conducted with higher doses of VP-16 in NSCLC patients, but related investigations into the treatment of small-cell bronchogenic carcinoma indicated that doses up to 3 g/m2 of VP-16 were well tolerated by patients. It is cautiously concluded that the combination of cisplatin and VP-16 probably offers an advantage over single-drug therapy with either agent alone in the treatment of non-small-cell lung cancer.

The role of etoposide epipodophyllotoxin (VP-16-213) in a combined modality treatment program incorporating local chest irradiation and combination chemotherapy with cyclophosphamide, Adriamycin (Adria Laboratories, Columbus, Ohio), and vincristine has been evaluated in a randomized trial of 165 patients with small-cell lung cancer. The overall response rate (complete response [CR] plus partial response [PR]) was significantly greater in the VP-16-213 arm (85% v 64%, P = .005) primarily as a consequence of improved response in patients with extensive disease (85% v 38%, P = .002 and 30% v 8% for CR only, P = .045). No differences in the response rates were observed in limited disease. The duration of response (months) was greater in the VP-16-213 arm (8.6 v 7.0 overall and 14.4 v 11.5 for CR) but not significantly so. Median survival times (months) were consistently greater in the group receiving VP-16-213 when analyzed according to extent of disease and response (10.6 v 9.5 overall; 15.0 v 13.6 for limited disease; 9.0 v 6.7 for extensive disease; 18.5 v 16.2 for CR overall; and 18.6 v 16.1 for CR in limited disease); the results were not statistically significant. The median survival of extensive disease patients attaining a CR was 15.3 months (range 3.2 to 34.3 + months) in the VP-16-213 arm and 7.4+ and 8.1+ months for the two patients with CR in the other group. Anemia and leukopenia occurred to a greater degree in the four-drug regimen, but no unusual or significant compounding toxicity (ie, neurotoxicity) was observed otherwise. Further investigation of this agent in combination chemotherapy programs for small-cell lung cancer appears to be warranted.

The effect and toxicities of Cis-containing combination chemotherapy were tested in 28 patients with primary lung cancer. All patients were treated with 80 mg/m2 Cisplatinum on the first day and 750 mg ftorafur p.o. every day. In addition to these drugs, patients with squamous cell cancer were treated with continuous subcutaneous infusion of 4 mg/m2 Peplomycin for 5 days and one shot i.v. of 4 mg MMC. Patients with adeno- and large cell cancer were treated with 30 mg/m2 Adriamycin and 4 mg MMC, while patients with small cell cancer were given 150 mg/m2 VP-16 p.o. for 5 days. The following results were obtained. Of 22 evaluable patients, overall response rate was 50%. In each histologic type, response rate was 50% (5/10) for squamous cell carcinoma 50% (4/8) for adenocarcinoma 33% (1/3) for large cell carcinoma and 100% (1/1) for small cell carcinoma. No CR was obtained in this series. Main side effects due to Cisplatinum were nausea, vomiting, loss of appetite, mild leukopenia and thrombocytopenia, mild elevation of serum creatinine and BUN and alopecia, all of which were transient. Interstitial pneumonitis was observed in 40% of patients with squamous cell cancer. Two patients with adenocarcinoma died within 3 weeks after treatment due to embolism of the abdominal aorta and myocardial infarction probably caused by treatment with Adriamycin.

Ninety previously untreated patients with histologically documented lung cancer were treated with VP-16 and cyclophosphamide either alone (protocol I) or with methotrexate (protocol II) or Adriamycin (protocol III), with 30 patients in each protocol. The rates of objective response were 57,37, and 27%, respectively, protocol I being significantly better than protocol III (P less than 0.05). Protocol I was significantly less toxic than protocols II(P less than 0.01) and III (P less than 0.001). The overall rate of objective responses was 66% in small cell (SCC) and 22% in non-small cell carcinoma (nSCC). Median survival was 37 weeks in SCC and 21 weeks in nSCC. Median survival of responders both in SCC and in nSCC was significantly longer than in nonresponders. We conclude that VP-16 plus cyclophosphamide is a well tolerated regimen with positive effect in advanced lung cancer. The association of methotrexate or Adriamycin didn't offer any improvement over the basic combination in this study.

Nabilone, a synthetic cannabinoid, and Prochlorperazine were compared in a double-blind crossover study of 34 patients with lung cancer undergoing a 3-day schedule of chemotherapy with Cyclophosphamide, Adriamycin and Etoposide. Symptom scores were significantly better for patients on nabilone for nausea, retching and vomiting (P less than 0.05). Fewer subjects vomited with nabilone (P = 0.05) and the number of vomiting episodes was lower (P less than 0.05); no patients on nabilone required additional parenteral anti-emetic. More patients preferred nabilone for anti-emetic control (P less than 0.005). Adverse effects common with nabilone were drowsiness (57%), postural dizziness (35%) and lightheadedness (18%). Euphoria was seen in 14% and a "high" in 7%. Erect systolic blood pressure was lower in nabilone patients on Day 1 (P = 0.05) but postural hypotension was a major problem in only 7%. Nabilone is an effective oral anti-emetic drug for moderately toxic chemotherapy, but the range and unpredictability of its side-effects warrant caution in its use.
