Sixty women with breast cancer (mean age: 61 years; range 36-78 years) were treated with Epirubicin (4'epi-Doxorubicin), 60 mg m-2, as single drug therapy. The drug was administered as 2 hours' constant rate infusions. The pharmacokinetics of the drug during the first course of treatment was evaluated by measurements of the plasma concentration of Epirubicin at the end of the infusion period. There was a five-fold inter-individual variation of the dose-normalized maximum plasma concentration, which increased with increasing age of the patients. There was no correlation between this pharmacokinetic parameter and degree of obesity. An increase in maximum plasma concentration was associated with an increasing degree of alopecia (p = 0.025). Also the degree of nausea and vomiting showed a tendency to increase with increasing maximum plasma concentration (p = 0.07). Fifty four of the sixty patients entered in the present study were evaluable for clinical response. There was one CR (complete remission). Seventeen patients achieved PR (partial response), and twenty five patients had SD (stable disease). Eleven patients did not respond to treatment. The median maximum plasma concentrations were 322, 316, 336 and 288 ng ml-1 in patients with CR, PR, SD and PD, respectively. The results in the present study showed that 60 mg m-2 of Epirubicin given as a constant rate infusion over 2 hours is a useful alternative to more aggressive combination drug therapy for the treatment of breast cancer.

A pharmacological, behavioural and nursing intervention strategy was evaluated for prevention of cisplatin (50 mg m-2) induced emesis in ovarian cancer patients. 46 patients received metoclopramide 2.5 mg kg-1 i.v., b.i.d., dexamethasone 20 mg i.v., lorazepam and biperiden as well as training in relaxation, nutritional advice and continuity in nursing care. Controls (n = 34) received standard treatment (metoclopramide 10-20 mg i.v. or dixyracin 20 mg i.v.). The intensity and duration of nausea and vomiting were significantly lower and measures of quality of life higher for patients on the experimental ward during the three cycles that were studied. No significant changes in emesis were observed between the cycles. There was no correlation between emesis and any of the parameters of quality of life measured. The reliability and validity of nausea ratings are discussed and we suggest that an underreporting of nausea and vomiting might be common.

Neoadjuvant chemotherapy consisting of 2-3 courses of cisplatin, vincristine, and bleomycin was used in the primary treatment of 36 consecutive patients with locally advanced early-stage cervical carcinoma [International Federation of Gynecology and Obstetrics (FIGO) stages Ib or IIa; tumor size, greater than or equal to 4 cm]. The effectiveness of the preoperative chemotherapy was evaluated in the surgical specimens. Among the 33 evaluable patients, the overall clinical response rate was 84.8%, which included a complete response in 8 patients (24.2%) and a partial response in 20 subjects (60.6%). No residual tumor was found in the surgical specimens obtained from 2 complete responders. This therapy induced varying degrees of tumor shrinkage and rendered radical surgery feasible in all evaluable cases despite the initial bulky size of the lesions. No significant difference was observed in the response rate according to age and disease stage. Lymph-node metastases were found after chemotherapy in 18.2% (6/33) of the patients. Grade II and III hematological toxicities occurred in 23.3% of the 90 chemotherapy cycles completed. Nausea and vomiting occurred to a mild to moderate degree in 75 (83.3%) cycles. These preliminary results suggest that the administration of induction chemotherapy involving two to three courses of cisplatin, vincristine, and bleomycin prior to surgery is effective in reducing the tumor volume and in providing better circumstances for surgical removal of the early yet bulky cervical tumors and results in tolerable toxicity. This protocol is now undergoing prospective randomized trials to test its impact on long-term survival.

Seventeen patients with hepatocellular carcinoma were treated by intraarterial injection of CTL suspension. The doses of CTL suspension, CDDP and THP(mean +/- SD)/injection were 4.1 +/- 1.6 ml, 81.9 +/- 31.6 mg and 13.5 +/- 5.2 mg, respectively. The therapy was given once in 10 patients, twice in 6 and 4 times in one. Over 50 per cent reduction in tumor size was obtained in 5 patients (30%). Fifty or more % decrease in serum alpha-feto-protein (AFP) levels was observed in 3 of 7 patients (43%) with the initial serum AFP level of more than 200 ng/ml, Fever, abdominal pain, nausea and vomiting were noted in most cases. However, they disappeared within 2 weeks after therapy was completed. No severe complications were encountered except one case of a liver abscess which healed by administration of antibiotics. No severe changes in laboratory data were observed. This study suggests that a new method of intraarterial injection must be developed to enhance the therapeutic effect even more, in addition to an increased injection dose of CDDP/THP-LPD and higher concentration of CDDP and THP in LPD.

In an attempt to improve the poor prognosis of invasive and/or high-grade bladder cancer after total cystectomy, we tried a combination of regional irradiation with hyperthermia (RH) therapy and systemic M-VAC (methotrexate, vinblastine, Adriamycin, and cisplatin) chemotherapy followed by surgery. The short-term results of these treatments were evaluated. A total of 17 patients received the combination of RH and M-VAC therapy between January 1989 and July 1990, and 12 then underwent total cystectomy. Of the 17 patients, 14 were evaluable for tumor response. The objective response rate was 64% (9/14), with 4 patients achieving a complete remission that was confirmed by histological examination. Nausea and vomiting were inevitable, and 71% (12/17) of the patients developed leukopenia. However, these side effects were not serious. Considering the previous results obtained using RH therapy in the absence of chemotherapy for this disease, no significant difference in the tumor response was detected between the RH only group and the RH plus M-VAC group. The long-term results cannot yet be evaluated, but we will continue to follow these patients in the future so as to clarify the usefulness of M-VAC therapy as preoperative therapy.

A series of 31 patients with advanced urothelial cancer were treated with combination chemotherapy consisting of 1-4 cycles of methotrexate, vinblastine, doxorubicin, and cisplatin (M-VAC). Of the 31 patients, 29 had measurable and evaluable lesions. A complete remission was achieved by 4 of these 29 patients (14%) for 1-46 months. A partial remission was observed in 14 of the 29 patients (48%) for 1-9 months. Whereas bony and hepatic metastatic lesions did not respond, some nodal (7/12), pulmonary (4/8), and pelvic lesions (2/3) as well as primary bladder tumors (4/6) and a tumor marker (1/2) responded. Complete tumor remission was observed in nodal (2/12) and pulmonary (1/8) metastatic lesions, in invasive lesions to the prostate and seminal vesicle (1/1), and in primary lesions in the bladder (2/6), ureter (1/1), and urethra (1/1). Two of three patients with non-transitional cell tumors attained a partial remission for 1-7 months. Complete remission of the pulmonary lesions was obtained in a case of squamous cell cancer of the bladder with pulmonary metastases. The toxicity of this regimen was generally tolerable and included moderate to severe myelosuppression, mild to moderate nausea and vomiting, renal toxicity, and mucositis. These results suggest that the M-VAC regimen holds promise for the treatment of advanced metastatic transitional cell cancer as well as non-transitional cell cancer of the urothelium.

Didemnin B is a depsipeptide derived from a Caribbean tunicate (sea squirt) that has demonstrated antineoplastic activity against a variety of murine tumor models, including the L1210 and P388 leukemia, the B16 melanoma, and M5076 sarcoma cell lines. Based on these data, we designed a phase II trial in which 15 patients with measurable, unresectable colorectal cancer were treated with Didemnin B at an initial dosage of 3.47 mg/m2 over 30 minutes administered by intravenous infusion every 28 days; the dosage was altered in accordance with the toxicity observed, with only one patient requiring a dosage reduction for pronounced nausea and vomiting. No hematologic or nonhematologic toxicity developed. No complete or partial responses were observed. These results do not compare favorably with results of treatments using other single agents or combinations that are currently available for the treatment of advanced colorectal cancers. However, because of the tolerable levels of toxicity experienced by in our patients, it is possible that an insufficient dose of the medication was delivered. We concluded that Didemnin B is not active against of colorectal cancers at the dosage and schedule at which it was administered in this study.

CI-973, a platinum(II) derivative with a 2-methyl-1,4-butanediamine carrier ligand, has activity in cisplatin-resistant tumor models in vitro and in vivo. In a Phase I pharmacokinetic study, 31 patients were treated with CI-973 (24 to 50 mg/m2/day for 5 days; 28-day cycles) given i.v. over 30 min without routine antiemetic prophylaxis or hydration. Of the 29 patients evaluable for maximum tolerated dose determination, most had a performance status of 0 or 1, and most had received prior chemotherapy. Neutropenia was dose limiting at 40 and 50 mg/m2/day. Recovery from neutropenia was generally rapid with nadir counts and recovery usually occurring by Days 15 and 22, respectively. Drug-associated thrombocytopenia was uncommon and never severe, even in patients with Grade 4 neutropenia. Anemia was common, but did not appear dose related. Drug-related nausea and vomiting and changes in renal function were relatively infrequent and mild. No clinically evident ototoxicity was reported, although changes in audiograms were noted in several patients. CI-973 concentrations were measured in plasma ultrafiltrate and urine by high-pressure liquid chromatography. The harmonic mean terminal half-life was 2.0 h. The mean CI-973 renal and nonrenal clearance values were 42.3 and 37.4 ml/min/m2, respectively. The mean recovery of CI-973 in urine was 53% of the administered dose. The mean ratio of CI-973 renal clearance to creatinine clearance was 0.92. Total clearance correlated with creatinine clearance (r2 = 0.63). A relationship between toxicity, expressed as the percentage of reduction in absolute granulocyte count, and area under the CI-973 plasma concentration-time curve was found in a subgroup of "good-risk" patients. This relationship, described well by a sigmoidal Emax pharmacodynamic model, did not hold for patients with extensive prior therapy or poor performance status. A model for toxicity prediction based on dose and creatinine clearance has been derived and will be validated in future studies. The recommended Phase II dose of CI-973 is 30 mg/m2/day for 5 days.

Colonic cancer during pregnancy is rare. Herein we describe a case of adenocarcinoma of the transverse colon in a 29-year-old pregnant patient. Early diagnosis is difficult because the initial symptoms of colorectal cancer, such as abdominal pain, nausea and vomiting, constipation, and abdominal distention, are often attributed to a normal pregnancy. Management of colonic cancer during pregnancy depends on gestational age and operability of the tumor. Medical and surgical management considerations are discussed.

CI-921, (9-[[2-methoxy-4-[(methylsulfonyl)amino]phenyl]amino]- N,5-dimethyl-4-acridinecarboxamide 2-hydroxyethanesulfonate (1:1)), an anilinoacridine derivative with activity in experimental solid tumors was studied in a multicenter phase II trial in patients with solid tumors. Eligible tumor types included cancers of the breast, stomach, pancreas, nonsmall cell lung, small cell lung, colon, head and neck area, and melanoma. Prestudy requirements included an ECOG performance status of < or = 2, no CNS metastases, and measurable disease. CI-921 was administered intravenously over 1-2 hours on days 1, 8, and 15 of a 35-day course at an initial dose of 270 mg/M2, with modification in subsequent courses based upon tolerance. Principal toxicities included leukopenia, marked phlebitis, and mild nausea and vomiting. One hundred fifty patients were entered of whom 132 were evaluable for response. There was one complete and one partial response among 19 patients with breast cancer, and two partial responses, one each among 14 head and neck and 36 nonsmall cell lung cancer patients.
