Sixty-seven patients with hematological malignancies and 4 with cancers were evaluated in this study. Standard administration of MCNU was instituted intravenously using 50-100 mg/m2 every 2 or 4 weeks, whereas some cases were treated with a higher dose therapy. Of 10 patients with chronic myelogenous leukemia, 7 achieved complete remission (CR), and 1 achieved partial remission (PR). A good response was also obtained in 9 of 10 patients with polycythemia vera and in all 4 patients with essential thrombocythemia. MCNU was less effective in malignant lymphoma (ML) and multiple myeloma (MM) than in myeloproliferative disorders. Two of 15 patients with ML and one of 21 patients with MM achieved CR, and two with ML and three MM achieved PR. Three patients with lung cancer and 1 with gastric cancer showed no response to MCNU. Delayed anemia, leukocytopenia and thrombocytopenia were observed in 38.7% of patients, and these were regarded as major side effects of MCNU. Nausea, vomiting, anorexia and elevated transaminase were also found in about 24% of patients, but only transiently. Our study indicates that MCNU is useful for chemotherapy of hematological malignancies, especially of myeloproliferative disorders. Therefore, further studies on combination chemotherapy with MCNU should be developed.

Forty-one patients (30 males, 11 females; mean age 49.7 years) with diagnosis of the "non-oat cell" type of lung cancer were studied. All patients were included in a randomized treatment design (regimens A and B) and completed six full cycles of polychemotherapy. Only 28 of the 41 patients proved evaluable. The performance status was 0-2 in 20 subjects (71.4%) and 3-4 in 8 (28.6%). The total number of patients achieving partial and complete responses was 20 (71.4%), of whom 14 (70%) received CDDP and the other 6 DDR. A progression of the disease was seen in 8 patients (28.6%), of whom 5 (62.5%) received DDR and the other 3 (37.5%) CDDP. An increase in body weight (3-8 kg) was observed in 15 patients (53.6%). Twenty-four of the 28 patients (85.7%) had a subjective feeling of well-being throughout the 6 cycles of chemotherapy. Nausea and vomiting and alopecia were the most frequent side-effects. The most important complications were paralytic ileus in 2 cases and a darkish manifestation in forearm and hand tissue due to vinblastine extravasation in another 2 cases. Haematological toxicity was found to be acceptable: leucopenia (less than 3.000) in 30 patients (73.2%); and thrombocytopenia (less than 100.000) in 12 patients (29.2%), which proved reversible. Some modalities relative to treatment schemes and the incorporation of additional agents are discussed.

A phase I trial of a new anthracycline derivative, 4'-O-tetrahydropyranyldoxorubicin (THP), was conducted in 54 patients with various advanced solid tumors and malignant lymphomas. Starting dose was 5 mg/m2 i.v. and dose escalations were made by a modified Fibonacci search scheme. There were 40 evaluable courses. The dose-limiting toxic effect was leukopenia which was dose-related and reversible. The maximum tolerated dose for a single i.v. injection was estimated to be 55 mg/m2. The median nadir day for leukopenia was day 12 with recovery occurring 13 days (median) after reaching the nadir. Thrombocytopenia was less commonly observed than leukopenia. Other toxic effects were mild gastrointestinal disturbances, fever and general malaise. Ventricular extrasystole was observed in a case of pancreatic cancer who received 5 mg/m2 of the drug. There were no cases with alopecia, or with hepatic or renal dysfunction. With regard to objective tumor response, CR was observed in 2 cases with NHL, and MR in 2 cases with lung cancer, and 1 case each with breast cancer and NHL. Response occurred at a dose of more than 35 mg/m2. The recommended dose schedule for phase II trial is 35-45 mg/m2 by single i.v. injection at 3-4-week intervals.

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.

Although it is generally accepted that anti-cancer chemotherapy should be administered at the maximum tolerable dose, it is not clearly established that the therapeutic results at dosage levels involving maximum tolerable toxicity are really superior to those with lower, better tolerated doses. 392 patients with advanced primary lung cancer were treated with 5 chemotherapy regimens including cyclophosphamide, methotrexate, vincristine, procarbazine, hydroxyurea, adriamycin and CCNU, in combinations of 3 to 7 agents. Response rates of 50% and over were registered after 8 weeks of treatment. During the same time the intensity of leukopenia, thrombocytopenia, vomiting, other digestive toxicity, neurologic disorders and alopecia was graded according to the worst observation from 0 to 4. The results show that there is no correlation between the grade of toxicity and the rate of response either for the whole group or for subgroups of patients as defined by cell type, degree of dissemination, age, or performance status. They demonstrate that the search for maximum tolerable toxicity is not a sine qua non for the best possible response to chemotherapy in primary lung cancer.

Thirty-one patients with metastatic brain tumors (MBT) from lung cancer and ten patients with MBT from melanoma received BCNU, 100 mg/m2, every four weeks by intracarotid and/or vertebral artery infusion into each involved site. Twenty-five patients with lung cancer and all melanoma patients are currently evaluable. Twelve patients with lung cancer had complete and partial responses lasting from 1 to 14 months. Four of them with the histologic diagnosis of small cell carcinoma, one with large cell carcinoma and one with squamous cell carcinoma showed complete response. None of the patients with melanoma MBT experienced any response. All of the patients had periorbital erythralgia and/or occipital pain during the infusion. Four patients manifested mild focal seizures during the infusion or 6 to 24 hours after the treatment. Transient confusion with disorientation was observed in two patients 4 and 24 hours, respectively, after a BCNU infusion. Two patients developed reversible thrombocytopenia after the fifth course of the IA chemotherapy. Median survival of patients with MBT from lung carcinoma was 4 months, with two of them still alive at 10 and 14 months, respectively. Only one patients of the 25 with lung carcinoma died from MBT. Failure to control the primary disease resulted in the deaths of a vast majority of the patients.

Fifty-three patients with advanced lung cancer refractory to chemotherapy with MACC (methotrexate, adriamycin, cyclophosphamide, and CCNU) were treated with a combination of mitomycin-C, etoposide, cisplatin, and hexamethylmelamine (MEPH). Among 45 evaluable patients, there were seven partial responders (16%), including 2/18 adenocarcinomas, 3/13 small cell anaplastic carcinomas, 1/5 large cell anaplastic carcinomas, and 1/9 squamous cell carcinomas. Major toxic side effects included thrombocytopenia (30/45 patients), leukopenia (22/45 patients), and emesis. Renal toxicity occurred in three patients, and cardiac arrhythmia was observed in one patient. Despite a low response rate, which was expected in this group of heavily pretreated patients with poor prognostic characteristics, these data suggest a lack of cross-resistance between MEPH and MACC.

A phase II study of KW 2083 [7-N-(p-Hydroxyphenyl)-Mitomycin C] was carried out in 14 cases of stomach cancer, 5 of lung cancer, 5 of colon cancer and 5 other types of cancer. KW 2083 was intravenously injected at a dose of 40 mg/body weekly in 26 cases. Among 23 evaluable cases, partial response was obtained in 6 cases (26%). The PR cases were 4 of stomach cancer and 2 of lung cancer, the former being all undifferentiated adenocarcinoma. Regarding hematologic toxicities, thrombocytopenia was the most principal toxicity and an important weak point of KW 2083. Thrombocytopenia (less than 75,000/mm3) was observed in 13 cases (50%). Recovery took about 4 weeks, but by that time 3 cases had still not recovered to 75,000/mm3. leukocytopenia (less than 3,000/mm3) was observed in 17 cases (65%). Concerning gastrointestinal symptoms, anorexia occurred in 11 cases (42%), nausea and vomiting in 11 cases (42%), diarrhea in 1 case and stomatitis in 1 case. T1/2 (beta-phase) of KW 2083 was half that of Mitomycin C.

4'-Epi-doxorubicin (4'-epi-DX) is a new doxorubicin derivative that in phase II human studies has been demonstrated to be less toxic than doxorubicin. Sixty-four patients with advanced solid tumors were treated with the drug combination of 4'-epi-DX and cis-dichlorodiammineplatinum (CDDP) at the doses of 40-60 and 50 mg/m2, respectively, every 21-28 days. Out of 52 evaluable patients, complete remission (CR) was recorded in 5, partial remission (PR) in 12, minor remission (MR) in 7, no change (NC) in 16 and progression (P) in 12. The median duration of remission in patients who achieved a CR and PR was 9+ months. In particular, out of 19 patients with ovarian cancer, 2 CR (second look) and 7 PR have been documented. One CR and 3 PR also have been observed in 21 patients with lung carcinoma. Complete and partial responses also have been documented in breast cancer (1 CR/1), in bladder carcinoma (1 CR/2), in renal cancer (1 PR/5) and in testicular cancer (1 PR/1). Hematologic toxicity was generally mild to moderate (leukopenia less than or equal to 1500 cells/mm3 in 3% of the patients; thrombocytopenia less than or equal to 120,000 cells/mm3 in 2% of the patients). Vomiting was present in almost all patients while alopecia has been recorded in 63% of the patients. No case of cardiac toxicity had been observed up to now (median cumulative dose of 4'-epi-DX:240 mg/m2, range 40-650 mg/m2). The combination of 4'-epi-DX with CDDP appears to be an active and well-tolerated regimen in ovarian cancer and lung cancer.

4'-Epi-doxorubicin is a new anthracycline analog with reduced cardiac toxicity in animal studies. A phase-II study was performed in 17 patients predominantly with non-small-cell lung cancer. All suffered from recurrent or advanced tumors and 7 of 16 evaluable patients had been pretreated with an alternative chemotherapy. 4'-Epi-doxorubicin was applied at a dose of 75 mg/m2 every 3-4 weeks. The median total dose was 280 mg (range: 130-250 mg). Only one patient with epidermoid lung cancer (overall response rate: 6%) showed a minor response and stable disease was observed in six other patients with bronchogenic carcinoma. Myelosuppression was rare and moderate: leukocytopenia of less than 2,000/mm3 occurred in 25% of patients and thrombocytopenia of less than 100,000/mm3 in 8% of patients. The frequency of alopecia and gastrointestinal side effects was 88% and 80%, respectively. Persistent electrocardiographic alterations were recorded in 2 of 14 (14%) patients. One of four patients revealed a marked reduction of left ventricular ejection fraction in radionuclide cardiography. It is concluded that 4'-epi-doxorubicin is not superior to adriamycin in this low-prospect treatment area, but studies with increased doses appear necessary in adriamycin-sensitive tumors because of recent reports from phase-III trials showing reduced cardiac and gastrointestinal toxicity with 4'-epi-doxorubicin in comparison with adriamycin.
