A phase I/pharmacokinetic study of the i.p. administration of teniposide (VM 26) was undertaken. Eighteen patients with various malignancies and refractory malignant ascites consented to enter this trial. The dose escalation was made according to the modified Fibonacci scheme. Twenty-four courses were evaluable for toxicity, response and pharmacokinetics. The maximum tolerated dose was reached at 450 mg/m2 and the limiting toxicity was myelosuppression, principally leukopenia. Abdominal pain occurred in one half of the courses but was not limiting. No partial remission, but two 'no change' were achieved for more than 2 months. A reduction or disappearance of ascites was seen in two patients. Pharmacokinetic studies, carried out in all courses, showed that the total exposure for peritoneal cavity averaged 10-fold greater than that of plasma. Based on the outcome of this phase I study, we could recommend phase II studies at a dose of 390 mg/m2 i.p. repeated every 4 weeks with a 4 h dwell-time.

Intra-arterial hepatic infusion chemotherapy combined with degradable starch microspheres (DSM) and mitomycin C (MMC) was performed for 9 patients with inoperable hepatic metastases from alimentary tract primary cancer. DSM, 45 +/- 5 micron in average diameter, produces temporary obstruction of arterial blood flow in the arterio-capillary bed and are subsequently degraded by serum amylase with T 1/2 of about 30 min. This intra-arterial treatment was repeated 2.3 times on the average. The average dose of DSM in a single infusion was 721 +/- 194 mg and the average total dose of MMC was 34.4 +/- 22.3 mg. Antitumor effects were evaluated in terms of tumor regression measured by CT scan and sonography. An objective tumor response was shown in 4/9 patients (44.4%): PR, 2/9; MR, 2/9. Elevated serum CEA levels of more than 3.0ng/ml were decreased in 7/8 patients (87.5%). Marked declines in the CEA level of more than 50% were observed in 4/8 patients (50%). Nausea and vomiting as well as abdominal pain were experienced in 8/21 treatments (38.1%) and 5/21 (23.8%), respectively. Furthermore, fever (2/21 : 9.5%), hepatic dysfunction (2/21 : 9.5%), and leukopenia (1/21 : 4.8%) were observed. All these side effects, however, were mild and transient. Thus, these results suggest that combined intra-arterial administration of DSM and MMC favorably enhances the antitumor efficacy of MMC.

A large granulosa cell tumor was believed to be responsible for causing obstruction and subsequent rupture of the small colon in a 10-year-old Quarter Horse mare. Two months earlier, a mass, tentatively diagnosed as granulosa cell tumor of the left ovary, had been identified by means of rectal palpation and ultrasonography. The mare was evaluated for clinical signs of acute, severe, abdominal pain, increased heart rate, cyanotic mucous membranes, clinical dehydration, with high PCV, leukopenia, and extreme abdominal distension. A large soft tissue mass and taut band that constricted the lumen of the small colon were palpable per rectum. Septic peritonitis was diagnosed on the basis of results of abdominocentesis. Exploratory surgery revealed extensive fecal contamination of the abdominal viscera, and the mare was euthanatized because of the resultant poor prognosis. At necropsy, the small colon was occluded by a taut, left broad ligament and the ovarian mass that was proved to be a granulosa cell tumor. The occlusion had caused impaction of the small colon, with subsequent perforation at the level of the broad ligament.

Forty-nine patients with liver metastases of breast cancer were treated with arterial infusion involving simultaneous use of adriamycin: 30-50 mg and mitomycin C: 10-20 mg through the hepatic artery by Seldinger catheter. Of 45 evaluable patients, there were 5 complete and 12 partial responses (CR + PR: 38%), 21 no change and 7 cases of progressive disease. The median duration of response was 5 months. The median survival time was 7.5 months in all cases, 8.7 months for responders and 6.4 months for non-responders. Leukopenia less than 4 X 10(3)/mm3 was observed in 73% of cases, thrombocytopenia less than 100 X 10(3)/mm3 in 35%, and a decreased hemoglobin value of more than 2 g/dl in 4%, but these were well tolerated. Nausea (53%), vomiting (43%), fever (12%), abdominal pain (6%) and liver toxicity (2%) were observed, but these were manageable. We conclude that this arterial infusion therapy is a useful treatment modality for controlling liver metastases of breast cancer.

Fifteen patients, median age 64 years, presenting with advanced gastrointestinal adenocarcinomas, were included in this study. The treatment combination consisted of folinic acid (200 mg/m2, IV bolus injection) followed by 5-fluorouracil (5-FU; 400 mg/m2, 30-min infusion) for 5 consecutive days and mitomycin C (10 mg/m2, IV bolus injection) on day 1, the therapy being resumed every 21 days. An objective response was noted in 7 of 15 patients (47%): 1 complete and 6 partial responses, including 4 of 5 patients who had received no prior chemotherapy and 3 of 10 patients who previously failed to respond to 5-FU. Objective responses were encountered in 4 of 7 stomach cancers, 2 of 3 pancreas tumors, and in only 1 of 5 colorectal carcinomas. Furthermore, 9 of 11 patients were completely relieved of their abdominal pain. The median duration of remission was 5 months. The median survival time of patients who responded to treatment was 7 months. Toxicity was acceptable, with mainly leukopenia and/or thrombocytopenia (5 patients) and oral mucositis (3 patients), leading to dose reduction. The combination of 5-FU+ folinic acid + mitomycin C appears to be a potentially effective regimen in the treatment of advanced gastrointestinal tumors, even in patients previously treated with 5-FU.

On the basis of its high degree of cytotoxicity against fresh human ovarian cancers and its relative lack of vesicant activity, mitoxantrone administered by the i.p. route was studied in a Phase I and pharmacokinetic trial. Thirty-three patients with good performance status and diagnoses of metastatic or recurrent ovarian (31 patients) and colon (two patients) cancers were treated with 12- to 38-mg/m2 doses, administered by the i.p. route every 4 wk for up to ten treatment courses. Mitoxantrone doses were escalated at 2- to 3-mg/m2 increments in groups of three to 11 patients. Thirty-eight mg/m2 (by i.p. dwell without removal) were considered the maximally tolerated dose in that, of eight treated patients, four experienced severe leukopenia and six experienced severe abdominal pain. Response to i.p. mitoxantrone was evaluable in 17 patients. None of seven patients with clinically measurable intraabdominal or pelvic tumor masses responded; however, in three (50%) of six patients with nonmeasurable disease, there was normalization of previously elevated serum CA-125 concentrations for 3, 17, and 24 mo. Additionally, two (50%) of four patients who underwent third-look laparotomies were found to have greater than 75% reductions in i.p. tumor masses with response lasting 24 and 25 mo. At 38 mg/m2, mitoxantrone was associated with a mean concentration.time product of 100 micrograms.h/ml in the i.p. space and of 0.071 micrograms.h/ml in plasma, yielding an i.p./plasma area under the curve ratio of 1408. We conclude that chemical peritonitis is the dose-limiting toxicity of i.p. administered mitoxantrone and that a dose of 23 mg/m2 every 3 to 4 wk should be used in future Phase II trials in ovarian cancer patients with minimal residual intraabdominal and pelvic disease following second-look laparotomy.

In a retrospective cohort study we reviewed our experience using D-penicillamine in children with low-level lead poisoning (whole blood lead levels 25 to 40 micrograms/dL) to determine its efficacy and the incidence of side effects. Two groups were compared: treated subjects (n = 84) were treated with penicillamine at a mean daily dose of 27.5 mg/kg; control subjects (n = 37) received no chelation therapy. Over a prechelation observation period of 60 days, lead levels (PbB) did not change in either group. With a mean period of 76 days of D-penicillamine therapy, PbB fell in treated patients by 33% (P less than 0.001). In 64 patients (76%), PbB was reduced to a currently acceptable range (less than or equal to 25 micrograms/dL). There were eight treatment failures (10%). In control subjects, mean PbB did not change significantly over 119 days of observation. Fourteen control subjects eventually required conventional chelation with calcium disodium ethylene-diaminetetraacetic acid, and 17 were lost to follow-up. Use of D-penicillamine was associated with an adverse reaction in 28 cases (33%); transient leukopenia occurred in eight, rash in seven, transient platelet count depression in seven, enuresis in three, and abdominal pain in two. Treatment was terminated prematurely in eight cases (10%) because of an adverse reaction. We conclude that D-penicillamine is effective therapy for selected children with low-level plumbism, but adverse effects can complicate or prevent its use in some patients.

Transcatheter arterial chemoembolization (TAE) and hepatic arterial infusion using totally implantable reservoir were performed for the treatment of liver metastasis of colo-rectal cancers, and their therapeutic effects, side effects and complications were evaluated. Eleven cases of H1 (metastasis in one lobe only), 7 cases of H2 (a few scattered metastases in both lobes), 12 cases of H3 (numerous metastases in both lobes) were entered into the study and underwent TAE 45 times. Gel foam, Ivaron and Lipiodol were used as embolic materials in combination with chemotherapeutic agents such as mitomycin C and adriamycin. Serum CEA level was decreased less than 50% of pre-TAE level 20 out of 32 (61%). The tumor size was regressed in 25% of TAE cases which were evaluated on the basis of CT scan. Abdominal symptoms including abdominal pain, nausea and vomiting and fever, leukocytosis, elevated GOT, LDH and bilirubin level were seen after TAE therapy. Median survival of H1, H2 and H3 cases were 21 months, 8 months and 4.5 months, respectively. Another 21 cases (H1, 5 cases: H2, 3 cases: H3, 13 cases) of liver metastasis of colo-rectal cancers were treated with selective hepatic arterial infusion therapy using totally implantable reservoir. Reservoir catheters were implanted into hepatic artery via gastroduodenal artery under direct vision at laparotomy. Mitomycin C, adriamycin and fluorouracil (5-FU) were used as chemotherapeutic agents. No particular side effect such as leukopenia or liver dysfunction was noted. Median survival of H1, H2 and H3 cases treated with arterial infusion were 4 months, 9 months and 9 months, respectively. Median survival of TAE cases and arterial infusion cases was 10 and 6 months, respectively. Thus, the survival rate of cases treated with TAE was better than that of cases treated with arterial infusion.

Twenty-five patients with advanced measurable gastric carcinoma were treated with D,L-leucovorin (CF) (500 mg/m2) administered as a 2-hour infusion and FUra (600 mg/m2) iv push midinfusion. Patients were treated weekly for 6 weeks followed by a 2-week rest. Median age was 57 (range 32 to 82). Median Eastern Cooperative Oncology Group (ECOG) performance status was 2 (range 0 to 4). Thirteen patients had progressed on previous combination chemotherapy that included FUra. At the time of this report, 19 patients were evaluable for response: 3 patients had partial responses, 8 had stable disease, and 8 progressed (but 3 of these received only 3 or fewer treatments before early disease-related death). Two of the responders were previously treated with FUra. Four patients were too early to evaluate. Measurable responses of greater than 50% were seen in bone, liver, lung, and an abdominal mass. Diarrhea occurred in 9 patients and FUra dose reduction was necessary in 8 of them. Other toxicities included lacrimation, rash, nausea, and mucositis. One toxic death occurred. Nine patients with gastrointestinal tumors confined primarily to the intra-abdominal space were treated with ip FUra in escalating doses (2 mM to 4 mM) in combination with D,L-CF in a 2-liter volume, either by 8 consecutive 4-hour dwells (7 patients) or once daily for 5 days (2 patients). The D,L-CF dose was 20.8 microM except for the first day of the 5-day schedule when it was 104 microM. Toxicity included leukopenia, mucositis, nausea and vomiting, skin rash, and abdominal pain. Three episodes of peritonitis resolved with antibiotics.(ABSTRACT TRUNCATED AT 250 WORDS)

Ofloxacin, a new fluoroquinolone, was given to fifty patients (29 females and 21 males) aged 25 to 86 years with urinary tract infection or prostatitis. Urinary tract infections usually chronic and associated with urologic anomalies, included 17 cases of cystitis and 19 cases of pyelonephritis. 14 patients had prostatitis. Pathogens recovered from the urine were 26 E. coli, 2 Citrobacter, 4 Proteus mirabilis, 2 Klebsiella, 2 Enterobacter, 3 Serratia, 3 Staphylococcus aureus and 11 Pseudomonas. Minimal inhibitory concentrations of ofloxacin ranged from 0.03 to 0.12 microgram/ml (mean MIC: 0.6 microgram/ml) for 27 nalidixic acid-sensitive strains, and from 0.25 to 4 micrograms/ml (mean MIC: 1 microgram/ml) for 26 nalidixic acid-resistant strains. Ofloxacin was given as single drug therapy in all patients, in a daily dosage of 200 mg b.i.d. in 46 patients and 400 mg b.i.d. in 4 patients, for 7 to 97 days (average 40 days). Follow-up after discontinuation of treatment was 3 to 12 months. Therapeutic results were as follows: 17 cures for the 17 cystitis patients, 17 cures and 2 failures by relapse for the 19 cases of pyelonephritis, and 11 cures, 1 failure by persistence of bacteriuria and failure by relapse for the 14 cases of prostatitis. Digestive disorders, i.e. nausea, abdominal pain, constipation, occurred in 6 patients and required withdrawal of the drug in 1; candidiasis of the tongue was recorded in one patient and digestive complaints with neuropsychic disorders in another. Two patients had short-lived, moderate leukopenia with granulopenia and one had transient worsening of preexisting renal failure. Hepatic tolerance was good.
