Twenty previously untreated patients with advanced colorectal adenocarcinoma were entered on a Phase II trial of 3-day continuous infusion cisplatin (25 mg/m2/day) and 5-fluorouracil (800 mg/M2/day) with oral calcium leucovorin (30 mg/dose) every 6 hours. There were four partial responses (20%) and two complete responses (10%) for a total response rate of 30% (95% confidence limits +/- 20%). Patients received a median of 4.5 cycles of therapy (range 2-9 cycles). Three patients experienced neutropenia; one had a life-threatening infection. One developed neuropathy at 375 mg/M2 cumulative dose. Four patients developed mucositis. Treatment was stopped for one patient with stable disease after 5 cycles because of anorexia and nausea and vomiting; treatment was stopped for four patients because of excessive fatigue. The median duration of responses was 4 months (range 3-6 months). Although this regimen is active, the response rate, cumulative nature of the toxicity, and the requirement for hospitalization led us to conclude that this regimen does not warrant Phase III testing but might be a basis for further Phase II therapeutic trials.

CI-921 (NSC 343499; 9-[[2-methoxy-4-[(methylsulphonyl)amino]phenyl]amino] -N,5-dimethyl- 4-acridinecarboxamide) is a topoisomerase II poison with high experimental antitumour activity. It was administered by 15 min infusion to 16 evaluable patients with non-small cell lung cancer (NSCLC) (7 with no prior treatment, 9 patients in relapse following surgery/radiotherapy) at a dose (648 mg/m2 divided over 3 days, repeated every 3 weeks) determined by phase I trial. Patients had a median performance status of 1 (WHO), and median age of 61 years. The histology comprised squamous carcinoma (11), adenocarcinoma (1), mixed histology (2), bronchio-alveolar carcinoma (1) and large cell undifferentiated carcinoma (1). Neutropenia grade greater than or equal to 3 was seen in 15 patients, infections with recovery in 3, and grand mal seizures in 1 patient. Grade less than or equal to 2 nausea and vomiting occurred in 66% courses and phlebitis in the infusion arm in 37%. 1 patient with squamous cell carcinoma achieved a partial response lasting 5 months. Further testing in this and other tumour types using multiple daily schedules is warranted.

4'-deoxydoxorubicin (DxDx) was administered to 17 patients with locally advanced or metastatic gastric adenocarcinoma. Treatment cycles were repeated every 21 days. 15 eligible patients with a Karnofsky performance status of 50% or better (median: 70%) received at least one course of treatment; a median of 2 courses of DxDx was delivered (range 1 to 13). The median dose per treatment course was 26 mg/m2 (range 8.5 mg/m2 to 53 mg/m2). 69% of patients required dose reduction following the first course of therapy due to grade 3 or 4 myelosuppression, primarily neutropenia. The principal side effects included anemia, mild gastrointestinal toxicities, and alopecia; one patient experienced a 10% decrease in cardiac ejection fraction without clinical cardiac toxicity. Of the 15 patients assessable for response and toxicities, 1 patient had a partial response lasting 2.5 months. The median survival from the time of the first treatment was 3.3 months. We conclude that DxDx has only limited activity in the treatment of advanced gastric adenocarcinoma.

Ten previously untreated patients with gastric cancer were treated with etoposide, 120 mg/m2 intravenously (i.v.) on days 4, 5, and 6, Adriamycin, 20 mg/m2 i.v. on days 1 and 7, and cisplatin, 40 mg/m2 i.v. on days 2 and 8 (EAP). Etoposide, 240 mg/m2 on days 4, 5, and 6, was administered orally instead of intravenously in alternating cycles, and pharmacokinetic studies were performed in those who had previously undergone gastrectomy or who had tumor infiltrating the stomach to determine oral bioavailability. Nine patients had advanced measurable gastric cancer, and one patient had an elevated carcinoembryonic antigen after surgery for synchronous gastric and colon cancer. The median age was 54 years (range 38-69), and the median Eastern Cooperative Oncology Group (ECOG) performance status was 2 (range 0-3). Nine of 10 patients had poorly differentiated adenocarcinoma. Twenty-four cycles were administered to 10 patients, and hematologic data were available for 23 courses. ECOG grade 4 neutropenia and thrombocytopenia developed in 19 (83%) and 8 (53%) courses, respectively. Thirteen courses (54%) were complicated by fever requiring parenteral antibiotics. Two patients (20%) died due to neutropenic sepsis. The profound myelotoxicity observed in our study prompted us to terminate the investigation prior to completing accrual. The oral bioavailability of etoposide was 21% and 36% in the two patients who had had prior gastrectomy.(ABSTRACT TRUNCATED AT 250 WORDS)

Twenty-nine evaluable patients with colorectal adenocarcinoma were treated in a phase I-II trial of combination chemotherapy with a 72-h continuous infusion of cisplatin (CDDP) and 5-fluorouracil (5-FU) with an infusion of VP-16 given at 24 and 48 h after the start of therapy. There were five (17 +/- 14%) partial responses lasting 2-6 months (median, 3). Three of these responses occurred among the 10 previously untreated patients. The toxicity of this regimen was pronounced. Four of eight patients with severe neutropenia required hospitalization for infections, two of which were life-threatening; one of six patients with severe thrombocytopenia had a life-threatening hemorrhagic complication; and four patients experienced severe, dose-limiting fatigue. These complications occurred principally with CDDP and VP-16 at doses above 27.5 mg/m2/day and 110 mg/m2/dose, respectively. Mucositis occurred in six patients and limited the dose of 5-FU to 1,300 mg/m2/day. Although the response rate appeared to be high in previously untreated patients, the minimal palliative benefit of treatment and the brief duration of the responses do not compensate for the toxicity observed.

Fifty-three patients with recurrent and advanced stage (III and IV) non-small-cell lung cancer (NSCLC) were treated with a combination of bleomycin, etoposide (VP-16-213), and cis-diamminedichloroplatinum (BEP). Forty-eight patients were appraisable for response. The response rates were 44% for the entire group, 57% in 30 patients with combined squamous-cell and large-cell carcinoma, and 22% in 18 patients with adenocarcinoma (40%, 50%, and 19%, respectively, if patients not appraisable for response are included as nonresponders). The median survival time of patients with squamous-cell and large-cell carcinoma was slightly longer than that of patients with adenocarcinoma (23 weeks v 19 weeks). Patients with responsive disease survived significantly longer (median, 34 weeks) than did patients with unresponsive disease (median, 16 weeks) (P = .001). In the entire group, the median survival time of patients with an Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1 was better (23 weeks) than of those with a status of 2 or 3 (15 weeks), but this difference was not seen in the subgroup with squamous-cell and large-cell carcinoma (24 weeks v 23 weeks, respectively). Thus, the performance status was not of prognostic value in the histologic subgroups experiencing the best response rate. There were two treatment-related deaths, but otherwise the toxicity of BEP was acceptable. Only four of the 119 treatment cycles were followed by fever even though there was significant neutropenia (0.5 X 10(9)/L) after 20 of 97 treatment cycles. The majority of patients receiving BEP experienced relief of cough, hemoptysis, pain, and fatigue associated with their disease. There was a good correlation between objective responses and palliation of symptoms. Thus, BEP offers good palliation, particularly for patients with squamous-cell and large-cell lung cancer.

Between October 1980 and December 1985, 50 patients with esophageal cancer were treated with combined radiotherapy and chemotherapy (5-fluorouracil [5-FU] and mitomycin C). Thirty patients with stage I or II disease received definitive treatment consisting of 6,000 cGy in 6 to 7 weeks and 5-FU (1,000 mg/m2/24 h) as a continuous intravenous (IV) infusion for 96 hours, starting on days 2 and 29. Mitomycin C (10 mg/m2) was administered as a bolus injection on day 2. Twenty patients received palliative treatment (5,000 cGy plus chemotherapy) for stage III or IV disease (extraesophageal spread or distant metastases). All patients treated in this program had an Eastern Cooperative Oncology Group (ECOG) performance status of 0, 1, or 2. Of the 30 definitively treated patients, 23 had squamous cell cancer, while seven had adenocarcinoma. Follow-up ranged from 6 months to 63 months. The complete response rate at 1 to 3 months following completion of treatment was 87% (26 of 30) documented by barium swallow and endoscopy (+/- biopsy). The actuarially determined local relapse-free rate at 1 year and beyond was 73%, and the actuarial survivals at 1, 2, and 5 years were 68%, 47%, and 32%, respectively. Of the 20 palliatively treated patients, ten had squamous cell carcinoma, eight had adenocarcinoma, and two had undifferentiated carcinoma. Seventeen patients were evaluable for freedom from dysphagia 1 or more months following completion of treatment. Eighty-two percent of evaluable patients (14 of 17) had no dysphagia posttreatment, while 64% (11 of 17) remained free of dysphagia until death or last follow-up, emphasizing the significant local control of those patients. The median survival for this group was 8 months. Treatment was well tolerated, and acute toxicity included esophagitis, stomatitis, oral candidiasis, and hematologic toxicities of thrombocytopenia and neutropenia. Late toxicities were predominantly manifested as a mild to moderate benign stricture, which required dilatation in four patients. One patient developed a perforation into the mediastinum in the absence of tumor, while two patients with persistent local disease developed tracheoesophageal fistula, and radiation pneumonitis was observed in two patients. This combination of radiation therapy with infusional 5-FU and mitomycin C is an effective and relatively well-tolerated regimen in the treatment of esophageal cancer. Surgical resection may not be necessary when high-dose radiation and chemotherapy are used.

Iproplatin (CHIP) was administered to 35 previously treated women with metastatic adenocarcinoma of the breast. The drug was given at a dose of 45 mg/m2 intravenously for 5 consecutive days and was repeated every 28 days. In this trial, there was one partial response and two patients with stable disease out of 29 evaluable patients. The median duration of response in patients with either a partial response or stable disease was 4.8 months. Myelosuppression was the major toxicity, 11 patients had severe thrombocytopenia and 3 severe neutropenia. Mild renal insufficiency, anemia, and nausea and vomiting were also noted. Iproplatin has limited activity in heavily pretreated women with advanced breast carcinoma; further studies in patients less heavily treated may show an improved response rate.

A total of 23 patients with advanced gastric adenocarcinoma were treated with a combination of moderate-dose methotrexate (MDMTX), 250 mg/m2 i.v., with folinic acid rescue and 5-fluorouracil (5-FU) 600 mg/m2 i.v. Therapy was given every 7 days for 4 courses and then at 14-day intervals. All patients were evaluable for response. No complete responses occurred, but five patients (22%) had partial remissions (95% confidence limit, 5%-39%). The median duration of remission was 6 months, with a median survival of 11 months amongst responding patients. In all, six patients (26%) had stable disease for a median period of 5 months. The overall median survival was 6 months. Therapy was generally well tolerated, with principal toxicities consisting of neutropenia, nausea and vomiting, mucositis and diarrhoea. In terms of activity or survival in advanced gastric carcinoma, the combination of moderate-dose MTX and 5-FU does not appear to offer an advantage over single-agent therapy.

Eighty-seven patients with histologically or cytologically proven non-small-cell carcinoma of the lung were treated with 4'-deoxydoxorubicin (DxDx) 30 mg/m2 every 3 weeks. Three responses (4%), all partial, were observed. All responses occurred in patients with large-cell anaplastic lung cancer and none in squamous or adenocarcinoma histologies (P less than 0.01). The durations of partial response for these three responders were 70, 198+ and 209+ days. The side effects noted were predominantly neutropenia, anemia, and weight loss. In three patients, declines in cardiac ejection fraction of 7%, 12%, and 23% occurred after cumulative drug doses of 150 mg/m2, 150 mg/m2, and 233 mg/m2, respectively. 4'-Deoxydoxorubicin had little activity in non-small-cell lung cancer at the dose used in this study.
