A Phase II clinical evaluation of 4'-epi-doxorubicin has been carried out in 100 patients with various types of solid tumors. Hematopoietic toxicity was dose-limiting but reversible and of mild to moderate degree. Other acute toxic manifestations such as vomiting and alopecia were qualitatively similar to those usually reported for doxorubicin, but lower in frequency and less severe. A number of responding patients received cumulative doses of 4'-epi-doxorubicin in excess of 500 mg/m2. One patient manifested reversible clinical congestive heart failure at cumulative dose of 1,080 mg/m2. Therapeutic activity has been observed in breast carcinoma, in rectal carcinoma and in melanoma. In chemoresistant tumors as rectal cancer and melanoma 4'-epi-doxorubicin deserves further study.

4'-Epidoxorubicin (epi-DXR) was tested in 56 patients with various types of advanced malignancies. The pattern of acute toxicity was similar to that of doxorubicin (DXR), but epi-DXR produced a lower incidence of vomiting, stomatitis, alopecia, and myelosuppression. The study of cardiac toxicity, utilizing only noninvasive methods, indicated that epi-DXR also is cardiotoxic. The increase in the systolic time intervals after the first dose as well as after cumulative doses was slightly lower compared with that observed after DXR. Antitumor activity occurred in a variety of tumors including malignant melanoma, renal cancer, and rectal cancer, which are refractory to DXR. Present results suggest that further studies with epi-DXR are indicated.

Forty-four patients with advanced colon or rectal cancer were treated with methyl-GAG on a weekly schedule. Of the 40 evaluable patients, 35 (87%) had received prior chemotherapy. Objective tumor regression was seen in six patients (one CR, five PR's). An additional nine patients had stable disease for a median of 42 weeks. The median survival (42+ weeks) for responding and stable disease patients was significantly better (p = 0.0001 Wilcoxan test) than those with progressive disease (11 weeks). Toxicity was reversible and included mild to moderate mucositis, nausea, vomiting, diarrhea, and thrombocytopenia. Responses observed in this study warrant further trials in patients with colon cancer who have no prior chemotherapy.

An early phase II cooperative study of Gemcitabine Hydrochloride (abbreviated to "gemcitabine" herewith) was conducted in patients with a variety of solid tumors (i.e., lung cancer, gastric cancer, pancreatic cancer, colon/rectum cancer, cervical cancer, ovarian cancer and breast cancer) at 56 institutions. The aim of the first step (Step I) was to investigate the feasibility of gemcitabine in a variety of different solid tumors, including lung cancer regarding efficacy and safety. The aim of the second step (Step II) was as a result of step I (Responses were observed) to continue to investigate the efficacy and safety of gemcitabine in chemonaive patients with non-small cell lung cancer. As a Step I study, gemcitabine was administered once weekly at a dose of 800 mg/m2 for a consecutive 3-week period followed by a week of rest, in multiple courses. Among the 29 eligible patients with lung cancer, partial response (PR) was achieved in 3 patients (25.0%, 95% confidence interval: 5.5-57.2%) out of 12 chemonaive patients. Adverse reactions (grade 3 or higher) seen in 29 patients with lung cancer were neutropenia (27.6%), leukopenia (13.8%), decreased hemoglobin (13.8%), thrombocytopenia (10.3%), malaise (6.9%), anorexia (3.4%), nausea/vomiting (3.4%), diarrhea (3.4%), dyspnea (3.4%) and interstitial pneumonia (3.4%). In other types of solid tumors, PR was achieved in 2 (8.7%) out of 23 eligible patients with cervical cancer and in 1 (5.3%) of 19 eligible patients with ovarian cancer, while the use of analgesics became unnecessary in 1 patient with pancreatic cancer. Incidence as well as severity of main adverse reactions in these patients were comparable to those seen in patients with lung cancer. A Step II study, in which gemcitabine was administered once weekly at a dose of 1,000 mg/m2 to chemonaive patients with non-small cell lung cancer, was conducted, referring to the results of Step I and clinical studies conducted overseas. The results of the Step II study demonstrated PR in 5 (14.3%, 95% confidence interval: 4.8 - 30.3%) out of 35 eligible patients with non-small cell lung cancer and that the main adverse reactions were comparable to those seen in the Step I study, posing no tolerability problems in particular.

Raltitrexed (Tomudex), a novel folate-based inhibitor of thymidylate synthase, has demonstrated anti-tumour efficacy comparable with 5-fluorouracil and leucovorin in patients with advanced colorectal cancer (CRC). This phase II study was conducted to evaluate the anti-timor efficacy and tolerability of raltitrexed in patients with advanced CRC who had received one previous chemotherapy regimen. Raltitrexed was administered at a dose of 3.0 mg/m2 i.v. over 15 min once every 3 weeks. Of 43 eligible patients, 53% had colon cancer and 47% rectal cancer. Objective responses were observed in 16% of patients [95% confidence interval (CI): 7-31%; seven partial responses). The median duration of response was 101 days (range: 45-239 days), the median overall duration of response was 145 days (range: 104-302 days) and the median survival was 11.6 months (95% CI: 9.4-14.7 months). Liver metastases showed a 17% (three of 18) response rate and lung metastases a 12% (three of 25) response rate. Adverse events of grade 3 or 4 reported for more than 5% of patients were neutropenia (23%), leukopenia (9%), reversible SGPT increase (7%) nausea/vomiting (19%), anorexia (14%), asthenia (9%) and hypotension (7%). Grade 3 or 4 diarrhea, stomatitis and alopecia were not observed. In summary, raltitrexed had an acceptable toxicity profile and promising anti-tumor activity against advanced CRC in patients who had received prior chemotherapy. Further clinical trials of combination chemotherapy using raltitrexed are warranted.

Tegafur is a prodrug of the antineoplastic agent fluorouracil, and is administered in a 1:4 molar ratio with the fluorouracil modulator uracil. Oral tegafur/uracil 300 mg/m(2)/day plus calcium folinate 75 or 90 mg/day for 28 days every 35 days was as effective as intravenous (IV) fluorouracil 425 mg/m(2)/day plus folinic acid 20 mg/m(2)/day for 5 days every 28 or 35 days in the treatment of patients with metastatic colorectal cancer in two large, randomised, nonblind, multicentre trials (n = 816 and 380). Median survival time among patients treated with tegafur/ uracil or fluorouracil was approximately 12 months in both trials. Results from both trials also demonstrated no significant between-group differences in overall response rates among patients treated with oral tegafur/uracil (12 and 11%) or IV fluorouracil (15 and 9%). In elderly patients (aged > or = 70 years) with metastatic colorectal cancer, results from small noncomparative studies showed that treatment with oral tegafur/uracil afforded overall response rates of 12.5 to 29% and was well tolerated. During preoperative treatment with oral tegafur/uracil plus calcium folinate as an adjunct to radiotherapy in patients with stage II or III rectal cancer, the maximum tolerated dosage of tegafur/uracil was 350 mg/m(2)/day (administered 5 days per week for 5 weeks). Among the 15 patients who were followed for 5 to 8 months, three had a complete response to treatment. Treatment with tegafur/uracil was also given postoperatively. The most common adverse events associated with oral tegafur/uracil were anaemia, nausea/vomiting, diarrhoea, thrombocytopenia, mucositis, neutropenia, asthenia, anorexia and abdominal pain. Oral tegafur/uracil was associated with a significantly more favourable tolerability profile than IV fluorouracil in the two large randomised trials. In particular, stomatitis and most adverse haematological events were less frequent.

The aims of this multicentre, randomised phase III trial were to evaluate: (1) the role of levamisol (LEV); and (2) the role of folinic acid (FA), added to 5-fluorouracil (5FU) in the adjuvant treatment of colorectal cancer. Patients with histologically proven, radically resected stage II or III colon or rectal cancer were eligible. The study had a 2x2 factorial design with four treatment arms: (a) 5FU alone, (b) 5FU+LEV, (c) 5FU+FA, (d) 5FU+LEV+FA, and two planned comparisons, testing the role of LEV and of FA, respectively. From March 1991, to September 1998, 1327 patients were randomised. None of the two comparisons resulted in a significant disease-free (DFS) or overall (OAS) survival advantage. The hazard ratio (HR) of relapse was 0.89 (95% confidence intervals (CI): 0.73-1.09) for patients receiving FA and 0.99 (95% CI 0.80-1.21) for those receiving LEV; corresponding HRs of death were 1.02 (95% CI: 0.80-1.30) and 0.94 (95% CI 0.73-1.20). Nonhaematological toxicity (all grade vomiting, diarrhoea, mucositis, congiuntivitis, skin, fever and fatigue) was significantly worse with FA, while all other toxicities were similar. In the present trial, there was no evidence that the addition of FA or LEV significantly prolongs DFS and OAS of radically resected colorectal cancer patients.

We sought to evaluate the efficacy and safety data of a combination regimen using weekly irinotecan in combination with capecitabine and concurrent radiotherapy (CapIri-RT) as neoadjuvant treatment in rectal cancer in a phase-II trial. Patients with rectal cancer clinical stages T3/4 Nx or N+ were recruited to receive irinotecan (50 mg m(-2) weekly) and capecitabine (500 mg m(-2) bid days 1-38) with a concurrent RT dose of 50.4 Gy. Surgery was scheduled 4-6 weeks after the completion of chemoradiation. A total of 36 patients (median age 62 years; m/f: 27:9) including three patients with local recurrence were enclosed onto the trial. The median distance of the tumour from the anal verge was 5 cm. The main toxicity observed was (NCI-CTC grades 1/2/3/4 (n)): Anaemia 23/9/-/-; leucocytopenia 12/7/7/2, diarrhoea 13/15/4/-, nausea/vomiting 9/10/2/-, and increased activity of transaminases 3/3/1/-. One patient had a reversible episode of ventricular fibrillation during chemoradiation, most probably caused by capecitabine. The relative dose intensity was (median/mean (%)): irinotecan 95/91, capecitabine 100/92). Thirty-four patients underwent surgery (anterior resection n=25; abdomino-perineal resection n=6; Hartmann's procedure n=3). R0-resection was accomplished in all patients. Two patients died in the postoperative course from septic complications. Pathological complete remission was observed in five out of 34 resected patients (15%), and nine patients showed microfoci of residual tumour (26%). After a median follow-up of 28 months one patient had developed a local recurrence, and five patients distant metastases. Three-year overall survival for all patients with surgery (excluding three patients treated for local relapse or with primary metastatic disease) was 80%. In summary, preoperative chemoradiation with CapIri-RT exhibits promising efficacy whereas showing managable toxicity. The local recurrence and distant failure rates observed after a median 28 months are low compared with standard 5-fluorouracil based therapy.

The standard adjuvant therapy for rectal cancer is 5-fluorouracil (5-FU) often combined with radiotherapy. Well-documented side effects of 5-FU include nausea, vomiting and diarrhoea, leukopenia and thrombocytopenia, hand-foot syndrome, mucositis, and cardiotoxicity. Peripheral neurotoxicity has only rarely been reported. We report a patient with a stage II rectal carcinoma who developed a mild axonal sensorimotor neuropathy at the end of a 5-FU therapy.

In this case report, we describe continuous subcutaneous infusion of opiates as PCAO (patient controlled analgesia in outpatients) in one patient with metastatic carcinoma of the rectum (liver and bone metastases, partial bowel obstruction) with severe cancer pain and vomiting in the terminal phase. The parenteral administration of opioids extended over 58 days. The infusion was powered by an external portable clockwork-driven syringe pump (Perfusor M, Braun Medical/Germany). The open-accessible pump has a syringe volume of 10 ml, and its maximal infusion time is 24 h. The 27-G infusion needle (Sub-Q-Set, Baxter/USA) was inserted in the side of the abdomen and was left in the same position for 10 to 20 days. It took the patient and his family only 1.5 h to familiarize themselves with the use of the pump. They were trained in its use in our outpatient pain department. For pain control both the variable continuous infusion and the extra injection doses could be administered by the way of the syringe driver. The patient was given a stock of 120 ampoules of morphine for further treatment at home. For optimal pain control he decided to raise the daily dose of opioid infusion from the initial 60 mg to 240 mg morphine within 48 h. In this way, PCAO-besides rapid titration of the opioid dose to achieve analgesia-allows the use of opioids controlled by the patient himself. In the present case this procedure was also important when an outpatient radiation therapy became urgently necessary to prevent a fracture of the spine because of metastasis. The pain control by the patient himself was the main factor to get free of pain during the transport to the hospital. Even positioning for radiation was possible without pain. When he received outpatient radiation therapy the patient needed extra injection doses of up to 360 mg morphine a day. The PCAO procedure by continuous subcutaneous infusion with opiates is a safe and efficient method of pain management for outpatient patients suffering from severe cancer pain and intractable nausea in the terminal phase. Its validity has also been proven especially for radiation treatment of bone metastases.
