Thirty patients with previously treated small cell lung cancer received salvage combination chemotherapy with etoposide and cisplatin. Two complete and six partial responses were observed, for a major response rate of 27%. Responses occurred promptly and sustained palliation was achieved among responders. Myelosuppression was the major dose-limiting toxic effect. A schedule of etoposide (115 mg/m2 iv on Days 1-3) and cisplatin (25 mg/m2 iv on Days 1-3 every 28 days) is recommended for further clinical trials.

Carboplatin, a cisplatin analogue without significant nephrotoxicity, was used as a single agent in the treatment of 56 patients with small cell lung carcinoma at a dose of 300-400 mg/m2 i.v. monthly. Twenty-three patients (41%) achieved a response including 5 (9%) complete remissions. Eighteen (60%) of 30 previously untreated patients achieved a response. The drug was well tolerated with nausea or vomiting in only 43% of patients and no nephrotoxicity was seen. Myelosuppression was dose limiting and 39% of patients developed leukopenia. In a subsequent study carboplatin in a dose of 300 mg/m2 was used in combination with etoposide 100 mg/m2 i.v. days 1-3, repeating monthly for 4 courses. So far 32 (89%) of 36 evaluable patients have achieved a response. In patients with limited disease 20/23 patients (87%) have responded including 7 (30%) complete remissions. Leukopenia was dose limiting and occurred in 83% of patients. Carboplatin is a highly active new drug in the treatment of small cell lung cancer.

Fourteen patients with small cell lung cancer (SCLC) received treatment with 1,2,4 triglycidylurazol (TGU) 600 mg/m2 or 800 mg/m2 as an IV bolus every 4 weeks. Twelve patients had received previous chemotherapy consisting of a five-drug regimen given for the short duration of only 9 weeks. All had measurable disease. Following TGU 11 patients had progressive disease and 3 patients had stable disease. The most frequent toxicity was nausea and vomiting, which occurred in all patients but was generally mild. Myelosuppression was common with a median white blood count nadir of 2.5 X 10(9)/l (range 0.9-7.4 X 10(9)/l) and median platelet count nadir of 76 X 10(9)/l (range 5-173 X 10(9)/l. Alopecia, thrombophlebitis, and hepatic or renal toxicity were not observed. In this study, TGU had no activity in SCLC, and the dose-limiting toxicity was myelosuppression.

Twenty-four patients with limited disease small cell lung cancer (SCLC) were treated with sequential hemibody irradiation (SHB) integrated into a conventional chemotherapy-local radiotherapy (LRT) program. Among 23 evaluable patients, 12 (52%) attained a complete response (CR) and 8 (35%) attained a partial response for an overall major response rate of 87%. The median time since study entry is 29 months. Durations of response are 9.9 months for all patients and 16.5 months for patients who achieved a CR. The primary site was the predominant area of recurrence. The median survival is 13.2 months for all patients and 23.2 months for the 12 patients who attained a CR. Myelosuppression, especially thrombocytopenia, was the major toxicity. Acute radiation toxicities and subacute pneumonitis previously associated with hemibody radiotherapy were well controlled or prevented using the current dose, premedication, and shielding techniques. This integrated program of systemic therapies with SHB and combination chemotherapy plus LRT is feasible for limited disease SCLC; it may prolong survival in patients who attain a CR but compared to similar programs without hemibody irradiation, there was no improvement in overall response rate, response duration, or survival.

After stratification for the extent of disease, previously untreated patients with small cell lung cancer randomized to receive therapy with the four-drug combination of cyclophosphamide, oncovin, nimustine hydrochloride (ACNU), and procarbazine (CONP) every four weeks (continuous regimen) or to receive CONP alternating with the three-drug combination of etoposide (VP-16), adriamycin and cisplatin (VAD) at four-week intervals (alternating regimen). Sixty-nine patients were entered in the study. Of 34 evaluable patients receiving the continuous regimen, six (17.6%) achieved complete response (CR) and 16 (47.1%) achieved partial response (PR). Of 31 evaluable patients receiving the alternating regimen, 10 (32.3%) achieved CR, and 16 (51.6%) achieved PR. There was a tendency in favor of the alternating regimen in CR and over-all response rates (0.05 less than p less than 0.1). There were no significant differences between the regimens in response duration or survival. The projected median survival times were 9.2 months and 9.4 months for the continuous and alternating regimens, respectively. One patient receiving the continuous regimen and three receiving the alternating regimen have been living for more than two years. The major toxicity was myelosuppression in both regimens. One patient died of hemorrhage due to thrombocytopenia during induction with CONP, and one patient died of cisplatin-induced renal failure. We conclude that alternating non-cross resistant chemotherapy leads to improved CR and response rates, but does not improve survival.

Ninety five patients (57 with limited disease and 38 with extensive disease) with previously untreated small cell lung cancer were entered into a study of short duration combination chemotherapy with intravenous cyclophosphamide (750 mg/m2) on day 1, adriamycin (40 mg/m2) on day 1, and etoposide VP-16 (100 mg/m2) on days 1, 2, and 3, with the addition on day 10 of methotrexate 50 mg/m2 with folinic acid rescue and vincristine 2 mg. The treatment was repeated on day 22 and only three courses were given. No maintenance chemotherapy was given, though patients with a complete response received radiotherapy (30-40 Gy (3000-4000 rads] to the primary site in most cases. Forty nine patients (86%) with limited disease achieved a response, with 26 (46%) complete remissions. Twenty five patients (66%) with extensive disease had a response, but only eight (21%) had a complete response. Actuarial survival analysis for the whole patient population showed a median survival of 13 months for patients with limited disease and seven months for those with extensive disease. The median survival was 14 months for those patients with limited disease who achieved a complete response, but only 10 months for non-responders. Myelosuppression was the major expression of toxicity. There were three deaths related to treatment and seven patients had febrile episodes during neutropenia that required antibiotics. Mucositis, which was usually mild, occurred in 49% of patients. The primary site was the main site of initial relapse in 56% of the patients who relapsed. Among patients with limited disease who achieved a complete response, relapses at the primary site were less common in those who received radiotherapy (five out of 12) than in those who did not (all eight). The results indicate that this short duration chemotherapy in small cell lung cancer gives response rates and the potential for long term survival similar to those obtained in other series while allowing patients the maximum time free from treatment.

Twenty-one previously untreated patients with extensive small cell lung cancer were treated with etoposide, 400 mg/m2/day for 3 consecutive days. Myelosuppression was severe, with a treatment-related death rate of 28%. Five partial responses were achieved. High-dose etoposide as given in this study produced unacceptable toxicity and no complete responses.

High-dose etoposide (1.0-1.5 g/m2) was given to 17 small cell lung cancer (SCLC) patients with metastases in the central nervous system. In 4 out of 9 evaluable patients with brain metastases and 4 out of 5 patients with meningeal carcinomatosis a response was seen. In all patients severe myelosuppression was observed. Three patients died of septicemia during the aplastic phase. Despite severe toxicity high-dose etoposide is potentially useful for CNS metastases of SCLC.

We undertook a phase 1 study of Carboplatin (CBDCA) on an intermittent single intravenous (IV) bolus (schedule A) and a 24-hour continuous infusion schedule (schedule B). Hydration and forced diuresis were not performed. Patients were not premedicated for anticipated vomiting. Thirty-eight adult patients with solid tumors received a total of 71 courses. In schedule A, doses were escalated from 20 to 600 mg/m2. The dose-limiting toxicity was myelosuppression. At doses of 270 mg/m2 and higher, leukopenia and thrombocytopenia were reproducibly seen. The dose of 600 mg/m2 was the maximally tolerated dose, producing severe thrombocytopenia (platelet counts less than 30,000/microL). Other toxicities included a fall in hemoglobin levels and tolerable nausea and vomiting. Schedule B produced comparable hematologic and emetogenic toxicities to those in schedule A. In three patients audiograms became abnormal with high-frequency hearing loss without overt deafness. Two patients developed hypomagnesemia without irreversible renal dysfunction. Patients with poor performance status, preexisting renal dysfunction, a third fluid space, or bone metastases seemed to develop increased hematologic toxicity. The recommended phase 2 dose for good risk patients is 400 mg/m2 IV bolus and for poor risk patients 270 mg/m2 IV bolus. Responses were seen in one patient each with head and neck carcinoma (partial response), small cell lung cancer (minor response), and breast cancer (minor response).

Twenty-five patients with measurable small cell lung cancer relapsing after first-line chemotherapy were treated with vindesine 3 mg/m2 IV on days 1 and 8 and hexamethylmelamine 100 mg/m2 PO on days 1-14, repeated every 3 weeks. Among 18 fully evaluable patients there was 1 partial remission lasting for 111 days. Two patients had disease stabilization for 127 and 152 days, respectively. Fifteen patients had disease progression. The treatment was well tolerated, myelosuppression being the major side-effect.
