The combination of sequential L-asparaginase and methotrexate (MTX) was evaluated in 33 patients with advanced refractory breast cancer. There were nine partial responses and one complete response, giving an overall response rate of 30% and a median duration of response of 8 months. Five of 17 patients (28%) who had received prior MTX at doses of less than 50 mg/m2 responded. Toxicity was acceptable. Moderate-to-severe stomatitis occurred in most patients and was the dose-limiting factor. Myelosuppression was minimal until the dose of MTX was escalated to greater than or equal to 180 mg/m2. The maximum tolerated dose of MTX was 280 mg/m2 and the median toxic dose was 220 mg/m2. These data indicate a selective "rescue" from MTX damage to normal target tissue by L-asparaginase. The antitumor effect observed even in patients who had been previously exposed to conventional doses of MTX suggests a possible improved therapeutic index of MTX given sequentially with L-asparaginase in this combination.

While carcinomas of the stomach is decreasing in incidence in the Dnited States, it is still a major cause of cancer death. But gastric neoplasms are not decreasing in some other geographic areas. According to some studies, 30% of all cancer in the U.S.S.R. originates in the stomach. The rate of gastric neoplasms is greatest in Japan, and over 54% of all cancer in the male population arises in the stomach. The peak age for development of stomach cancer is between 70 and 80 years; over 60% of all stomach cancer is diagnosed in patients between the ages of 60 and 70, while more than 10% is found in those over 80. The main hope for cure at this time rests with surgical treatment. However, despite increased use of surgery, the 5-year survival rate of approximately 13% for patients diagnosed during 1955-59 has not improved to any degree since that time. The major drugs commonly used to treat gastric cancer are 5-fluorouracil (5-FU) and mitomycin C. Controversy still exists concerning the optimum method for administering 5-FU, the most frequently used drug in the United States. The standard loading-course method was attended by a high risk of severe toxicity and drug-related deaths. Several variations of the loading course have evolved. Currently, the Mayo Clinic group uses a 5-day course of 13.5 mg 5-FU/kg repeated every 5 weeks, with therapy interrupted if stomatitis or diarrhea develops; with this regimen the drug-related mortality rate was reported to be less than 1%. Studies have shown that 5-FU plus radiotherapy can enhance survival in patients with locally unresectable diseases. The overall objective with 5-FU is 20-25% with an average of 4-5 months' duration of response. Despite the many patients treated with 5-FU, rarely has a systematic analysis been done of factors such as age, sex, disease-free interval, histologic grade of the tumor, or sites or metastases, which might predispose to a favourable or unfavorable response. In Japan the most commonly used drug for treatment of gastric cancer is mitomycin C, the second most frequently used drug in the United States. The overall objective response rate with mitomycin C is between 20 and 30%, with the higher response rates being reported in the Japanese data. The average duration of response ranges from 1 to 3 months. The nitrosoureas [1,3-bis(2-chloroethyl)-1-nitrosourea (BCNU), 1,3-cis(2-chloroethyl)-1-nitrosourea (CCNU), and methyl CCNU (MeCCNU)] have shown some evidence of activity against gastric cancer. BCNU has yielded an objective response rate of 18% (6/33) and an average duration of response of 4.5 months in gastric cancer patients, most of whom had no prior therapy. Adriamycin recently has been shown to have some antitumor activity, with an approximate response rate of 25%. Combination approaches have been more successful in stomach cancer than in any other gastrointestinal neoplasm. The Japanese have reported higher response rates with a combination of 5-FU, mitomycin C, and cytosine arabinoside...

A phase I study of a new anthracycline antibiotic, aclacinomycin A, was performed in a total of 15 patients with advanced malignancy to determine the maximum-tolerated dose. The gastrointestinal toxicity which occurred was not dose-related and was not severe. Epilation and stomatitis were extremely minimal. Both hepatic dysfunction and hematologic toxicity were dose-limiting. A recommended dose for phase II study was determined to be 2.5--3.0 mg/kg (approximately 100--120 mg/m2) given in 3-week intervals. Objective response was observed in two patients with malignant lymphomas.

Necrotizing lesions of the colon occur in patients with malignancy. We identified 26 patients with cancer (23 with acute leukemia and three with solid tumors) who died from necrotizing colitis. Autopsies revealed three pathologic categories: pseudomembranous colitis in 69 per cent, agranulocytic colitis in 19 per cent and ischemic colitis in 12 per cent. Most died from sepsis. A comparison of characteristics was made with a control population matched for diagnosis, age, cause of death and duration of neoplasia. Nearly all patients in both groups had fever and were granulocytopenic secondary to chemotherapy. Most received antineoplastic and antimicrobial regimens during the month prior to their terminal illness. Abdominal pain and distention, stomatitis and necrotizing pharyngitis were frequently associated with colitis. Hyperbilirubinemia was a frequent late complication in those with colitis and the control group. Single and multiorganism septicemia were found more frequently in patients with colitis. As antemortem diagnosis was unusual, aggressive attempts at diagnosis are necessary to assess the true incidence of this disorder and the best therapy.

In vitro production of interferon by blood leukocytes from patients with lymphosarcoma, lymphogranulomatosis, leukemia, cancer tumours, pneumonia, as well as by leukocytes of mice with Rauscher leukemia, and mice in the condition of hyporeactivity to interferon inducer was studied. Alongside with quantitative differences in interferon production, biological differences in the properties of interferons produced of normal and sick humans and animals were revealed. The biological differences consist in that the interferon produced by leukocytes from cancer and leukemia patients interacting with homologous cell culture is conducive to more rapid formation of resistance to the indicator virus than the interferon produced by normal leukocytes. Thus, resistance of the homologous cell culture to the infection with the indicator vesicular stomatitis virus developed within 1--2 hours after contact with leukocyte interferon from patients and only within 5--6 hours after contact with that of normal subjects. This finding is not specific for cancer and leukemia, as the same was observed with specimens from patients with pneumonia and from mice hyporeactive to interferon inducer. It is suggested that patients with cancer and leukemia have a state of interferon hyporeactivity.

A phase I clinical study of bruceantin was conducted in 66 patients with various types of advanced solid tumors to evaluate its toxicity and efficacy. The initial dose of 0.2 mg/m2/day x 5 days repeated at 2-week intervals was progressively increased to a maximum dose of 4.5 mg/m2/day. Hypotension was the dose-limiting toxic effect; it was delayed, cumulative, and occurred more often in patients with abnormal pretreatment liver function. Nausea, vomiting, and fever were common at higher doses, and diarrhea, stomatitis, alopecia, paresthesia, and rash were observed in some patients. The hematologic toxicity of bruceantin was moderate at high doses and was manifested mainly as thrombocytopenia; it was more severe in patients with abnormal hepatic and renal functions. No objective tumor regressions were observed. The recommended dose of bruceantin is 3.5 mg/m2/day x 5 days for phase II studies.

N-(Phosphonacetyl)-L-aspartic acid, an inhibitor of aspartate transcarbamylase, was administered to 25 patients with advanced cancer by 10-minute infusion daily x 5 consecutive days to determine the toxicity and to look for evidence of therapeutic effect. Planned dose escalations ranged from 100 to 1250 mg/m2 (daily dose). Nausea, vomiting, and diarrhea were the most frequent toxic effects, with three of six patients treated at a daily dose of 1250 mg/m2 having severe diarrhea. Other toxic effects were encountered rarely and were not dose-limiting; these included mild leukopenia, thrombocytopenia, rash, stomatitis, and increases in SGOT. One patient with a widely metastatic carcinoid of unknown origin had an objective response lasting 6 weeks.

Sixty-one patients with advanced disseminated cancer were given progressively increasing doses of pyrazofurin to evaluate toxicity patterns and to establish the dosage that produces maximum therapeutic effect with clinically tolerable toxicity. The drug was given by intravenous injection over 5-day courses repeated every 2--3 weeks. Toxic reactions included stomatitis, myelosuppression, skin rash, erythema, proctitis, and occasional nausea and vomiting. Stomatitis was the dose-limiting toxicity and it occurred in 32 patients. Myelosuppression was mild to moderate. Of 75 evaluable courses for marrow toxicity, leukopenia occurred in 14 and thrombocytopenia in 28. Thrombocytopenia was apparently dose-independet. Marrow recovery was complete by day 21 of therapy. Twelve patients developed mild or severe cutaneous toxicity depending on dose. When mild, the skin changes consisted of self-limited erythema or rash, and when severe, bullous lesions and skin ulcers were also observed. Proctitis occurred in six patients and was associated with severe stomatitis. Nausea and vomiting were occasional and mild. There was no evidence of liver or renal toxicity. All toxic manifestations other than marrow toxicity were dose-related. No responses were observed. A reasonable dose schedule is 45 mg/m2/day X 5 repeated every 3 weeks. We recommend that Phase II studies be pursued particularly in diseases that have been shown to be sensitive to the drug.

Adriamycin has been given to 442 patients using the weekly regimen as initially described by Bonadonna et al. Hematologic toxicity and clinical effectiveness have been similar to those described with regimens in which the drug is given every 3 weeks. Stomatitis is more frequent with the weekly regimen than with the usual triweekly regimen. The incidence of electrocardiographic changes and arrhythmias was similar to that reported in other studies. Nine patients received between 500 and 550 mg/m2, nine between 550 and 600 mg/m2, 28 between 600 and 1000 mg/m2, and 22 between 1000 and 2500 mg/m2. None of the patients developed definite evidence of cardiomyopathy although six showed some disturbance of myocardial function. In each of the six patients, factors other than adriamycin cardiotoxicity were believed to play a major role in the myocardial abnormality. The difference between the incidence of cardiomyopathy seen in this series and that previously reported is statistically significant. The reasons for the difference are not clear but are probably related to the schedule that was used.

A typical case of the recently described tumor-suspect lesion, necrotizing sialometaplasia (NS) of the palate, in a 54-year old Caucasian male is presented. Results of complete blood- and urinanalysis including serum electrophoresis and labial salivary gland biopsy strongly pointed at a local etiologic factor. Previous statements that the disease represents a new entity are questioned. The present authors favor the idea that NS is the necrotizing (ulcerative) or terminal stage of leukokeratosis nicotina palati (nicotinic stomatitis). It is of particular importance that this lesion is not diagnosed as a malignancy, as it heals spontaneously and uneventfully.
