We analyzed 52 cases of advanced or recurrent cancer of the cervix treated by intra-arterial infusion chemotherapy (IAIC) with or without radiotherapy. IAIC regimen was separated into two groups: Group I consisted of 5-FU + MMC +/- ADR (30 cases) and group II of CDDP + MMC +/- 5-FU (22 cases). The tip of the catheter was placed in the bifurcation of abdominal aorta or the bilateral internal iliac arteries (7 cases). The overall response rate (CR + PR) was 71%, 87% in patients given radiotherapy, 50% in those without radiotherapy, and 100% in primary cases. The five-year survival rate was 20% in primary cases, 14% in recurrent cases, 3% in Group I and 38% in Group II (p = 0.00182) by chemotherapy regimen. Severe (more than grade III) hematological acute side effect was 48% for all cases, but recovered by interruption of drugs. In 7 cases in which the tip of the catheter was placed in internal iliac arteries, there were severe skin ulcers in 2 cases and severe pain of leg or gluteal region requiring narcotics in 2 cases. These data suggest that IAIC mainly with cisplatin with or without radiotherapy is one of the effective treatments for advanced or recurrent cervix cancer. But we should check the blood flow distribution periodically, and control the concentration of drugs.

The status of chemotherapy for pancreatic cancer (PC) has been difficult to assess because of the problem of evaluating tumor response, which id dependent on the accurate measurement of tumor size using imaging modalities such as computed tomography. Recently, new assessment methods for chemotherapy in PC, which include clinical benefit response and tumor marker response, have been proposed. The clinical response is evaluated using two parameters; pain and performance status. In our trial of combined chemotherapy with 5-FU and cisplatin in PC patients, 4 (19 %) of 21 PC patients showed remarkable clinical benefit response. With respect to the tumor marker (CA 19-9 and CEA) response, responders, which were defined as patients whose levels were reduced by more than 50% of the pretreatment level, survived significantly longer than non-responders. These new methods may be useful for evaluating chemotherapeutic response and may provide a strong rationale for continuing chemotherapy in patients with stable disease or with non-measurable disease by imaging modalities.

Locally advanced cervical cancer has a poor prognosis, poor survival rate, and high local failure rate. A number of questions regarding the optimal agents and schedule of concurrent chemoradiation remain unanswered. To improve the cure rate for advanced or recurrent cervix cancer, we studied intra-arterial infusion chemotherapy (IAIC) with or without radiotherapy. We analyzed 52 cases of advanced or recurrent cervical cancer treated by IAIC with or without radiotherapy. IAIC regimen was separated into two groups: group I consisted of 5-FU + MMC+/-ADM (30 cases) and group II of CDDP + MMC+/-5-FU (22 cases). The tip of the catheter was placed in the bifurcation of abdominal aorta or the bilateral internal iliac arteries (7 cases). The overall response rate (CR + PR) was 71%, 87% in patients receiving radiotherapy, 50% in those without radiotherapy, and 100% in primary cases. The five-year survival rate was 20% in primary cases, 14% in recurrent cases, 3% in group I and 38% in group II by chemotherapy regimen. Severe (more than grade III) hematological acute side effects were found in 48% of all cases, but recovered by interruption of drugs. In 7 cases in which the tip of the catheter was placed in internal iliac arteries, there were severe skin ulcers in 2 cases and severe pain of leg or gluteal region which need narcotics in 2 cases. These data suggest that IAIC mainly with cisplatin with or without radiotherapy is one of the effective treatments for advanced or recurrent cervical cancer. But we should check blood flow distribution periodically, and control the concentration of drugs. To improve the survival rate for advanced or recurrent cervical cancer, we should discuss neoadjuvant chemotherapy followed by chemoradiotherapy and maintenance systemic chemotherapy.

Androgen receptors are present in both pancreatic cancer tissue and cell lines. Flutamide is a potent antiandrogen widely used in clinical practice for patients with metastatic prostate cancer. This Phase II trial was undertaken to evaluate the impact of flutamide in patients with advanced pancreatic adenocarcinoma who had developed progressive disease following therapy with one 5-FU-based regimen. Fourteen patients were treated with flutamide, 250 mg orally three times per day. Therapy was generally well tolerated. No patients achieved objective tumor response. No patient had improvement in tumor-related symptoms as measured by improvement in pain intensity, analgesic requirement, performance status, or nutritional status. Median survival was 4.7 months. We conclude that flutamide is ineffective second line therapy for patients with advanced pancreatic adenocarcinoma.

In all patients with advanced colorectal cancer, disease eventually progresses following fluorouracil (5-FU) therapy, with a worsening of disease-related symptoms and quality of life (QOL). Irinotecan (CPT-11 [Camptosar]) has produced response rates of 16% to 27% in patients with 5-FU-refractory colorectal cancer, along with a modest survival gain and possible palliative benefit. Disease-related symptoms and QOL are major end points of palliation, although few studies have assessed them as primary end points of response. The concept of palliative response benefit has been applied successfully to randomized trials of systemic therapy in prostate and pancreatic cancers. This article will describe how this concept has been used in the design of a current phase II trial assessing the palliative benefit of irinotecan in patients with 5-FU-refractory colorectal cancer. This trial uses disease-related symptoms and performance status as primary end points. Palliative response was defined prospectively as one or more of the following; (1) 50% decrease in pain score; (2) 50% decrease in narcotic analgesic usage; or (3) 10-point increase in Karnofsky performance scale from baseline for 4 weeks, without deterioration of any of these parameters. The difficulties in using patient-oriented end points as response criteria in this trial and in the clinic will be addressed.

Pancreatic cancer is widely regarded by medical personnel and the lay public as one of the most dreaded of all diagnoses. Although in selected series of operable patients the chance of long term survival may reach 20%, most patients have unfavourable disease at the time of diagnosis, and for the entire group of newly diagnosed patients, 5-year survival is rare. This grim outlook results from a combination of factors, including an anatomical location which makes early detection by screening tests or by symptoms difficult, a high tendency for spread to regional lymphatics and the liver, a poor profile of sensitivity to chemotherapeutic agents and the poor medical condition of many patients at the time of diagnosis. These factors mean that it is particularly important that at the time of diagnosis these patients are carefully evaluated, and that they and their families are fully aware of the treatment options available to them and the associated potential risks and benefits. For localised cancers, surgical resection alone offers the potential for long term survival. The addition of postoperative radiation therapy (RT) predictably improves local control but has minimal impact on survival, which is primarily determined by the development of liver metastases. Randomised trial data support the use of combined fluorouracil (5-FU) chemotherapy and RT in patients who have undergone pancreatectomy and have negative margins, although the benefits are modest and the relevant randomised trials enrolled relatively small patient numbers. For patients with marginally resectable tumours, the feasibility has been demonstrated of using chemotherapy plus RT to reduce tumour size before resection, but it is unclear whether this approach will benefit a significant number of patients. Tumours which are unresectable because of local advancement (involvement of major vessels or regional nodes) can be treated with RT alone or in combination with chemotherapy, but survival past 2 years is uncommon. Patients with liver metastases have a poor prognosis. As part of a programme of supportive care, some of these patients may receive cytotoxic therapy, the goal of which is to relieve cancer-related symptoms such as pain from the primary tumour or metastatic sites, or weakness, nausea and anorexia which may be associated with liver metastases. Although the objective response rate of chemotherapy agents is low, in an individual patient they may produce an adequate response and acceptable toxicity so that the patient experiences overall improvement in symptoms. The mainstay of chemotherapy for pancreatic cancer, as with other gastrointestinal cancers, has been fluorouracil. However, recent clinical data have shown that gemcitabine produces similar results in terms of response rate and survival, with more acceptable toxicity, so that the quality of life was judged to be better than with fluorouracil. Pancreatic cancer provides a fertile ground for testing new, biologically based approaches to cancer therapy because of the limited success of currently available treatments.

An 80-year-old woman with metastatic bone cancer from ascending colon showed a remarkable response to combination therapy of 5-FU and radiation. 5-FU (500 mg/day) was administered daily through intra-arterial catheter. The total dose of 5-FU was 15.5 g. Radiotherapy was performed (total radiation dose, 45 Gy). After therapy, metastatic lesions were remarkably reduced in size according to various imaging techniques, and the serum CEA level dramatically decreased from 249 ng/ml to 5.2 ng/ml. Other tumor markers such as CA19-9, NSE, and CYFRA were also dramatically decreased. Various tumor-related symptoms, especially the pain caused by tumor invasion, were also decreased. Drug toxicity caused slight nausea and leucopenia. These results suggested that the combination therapy of 5-FU and radiation is useful for the pain caused by metastatic bone cancer.

The aim of this prospective study was to assess the efficacy, clinical benefit and safety of CPT-11 (irinotecan) in patients with stringently-defined 5-fluorouracil-resistant metastatic colorectal cancer (CRC). 107 patients with documented progression of metastatic CRC during 5-FU were treated with CPT-11 350 mg/m2 once every 3 weeks in a multicentre phase II study. Tumour response and toxicity were assessed using WHO criteria. Changes in performance status (PS), weight and pain were also measured. The WHO response rate was 13/95 (13.7%, 95% CI 7.5% to 22.3%) eligible patients with a median duration of response of 8.5 months (37 weeks, range: 18-53+). There was also a high rate of disease stabilisation (44.2%) with a median duration of 4.8 months. The probability of being free of progression at 4 months was 50%. Median survival from first administration of CPT-11 was 10.4 months or 45 weeks (range: 3-66+ weeks). There was weight stabilisation or gain in 81% (73/90) of patients, a favourable outcome in PS in 91% (82/90) (improvement of WHO PS 2 or stabilisation of PS 0-1), and pain relief in 54% (26/48). There were no toxic deaths. Neutropenia was short-lasting and non-cumulative. Diarrhoea grade > or = 3 occurred in 7% of cycles and 28/107 (26%) of patients. CPT-11 350 mg/m2 once every 3 weeks has an encouraging degree of activity in progressive metastatic CRC truly resistant to 5-FU with a relatively high rate of tumour growth control translated into clinical benefit. The toxicity profile of CPT-11 is becoming better understood and has been considerably improved.

For the application of a kinetic model to PET data, it is generally necessary to obtain the arterial input function (AIF). It was the aim of the present study to introduce a method suitable for the determination of the AIF of a substance that undergoes biochemical transformation from noisy PET data: the population approach. F-18 labeled 5-fluorouracil (5-[18F]FU) was administered i.v. to eight patients suffering from liver metastases of colorectal carcinoma. Radioactivity concentrations in liver and aorta were dynamically measured with PET over 120 min. Pharmacokinetic analysis was carried out by applying a five-compartment model to individual activity-time data for the eight patients or to the mean activity-time data among the eight patients. The mean values of all parameters describing 5-FU transport and catabolism, i.e., volumes of distribution and clearances, as well as interindividual coefficients of variation (CV) were calculated according to both approaches. With our model, we were able to separate the concentration-time course of 5-FU in plasma, i.e., the AIF, from that of its major catabolite alpha-fluoro-beta-alanine (FBAL). As far as the mean parameter estimates are concerned, the differences between both approaches are not significant. For the liver data, the CV's are almost the same for both approaches. For the parameters concerning the aorta, however, there is a decrease in the CV's by using the population approach. For example, the CV of the central distribution volume of 5-FU was 30% for the individual approach and 18% for the population approach. With the population approach, it is possible to determine the AIF of drugs that undergo metabolic conversion, such as anticancer drugs, from the abdominal aorta visualized on PET images. The population approach helps to overcome noise in individual data. Since no measurements are needed in addition to the PET examination, the suggested method helps to reduce risk and pain for the patients as well as cost and thus facilitates large scale patient studies.

Stable disease is a category which is not included in the evaluation of the overall treatment response rate. In many studies with a response rate below 20%, chemotherapy almost doubles the survival of patients. In the most chemotherapy trials with advanced colorectal cancer patients, about 30-50% had stable disease. Despite belonging to the same category of therapy response, some patients with stable disease have achieved symptom improvement, but some have not. The aim of the study was to investigate whether the stabilization of the disease with clinical benefit is associated with benefit in survival. A total of 99 patients with advanced colorectal cancer were treated with carboplatin (80 mg/m2, day 1-7), 5-FU (750 mg/m2, day 1-5), leucovorin (100 mg/m2, day 1-5) every 4 weeks. After 4 courses, in the case of stable disease (SD), the patients were stratified according to clinical benefit achievement in: Group A--patients with clinical benefit who continued with chemotherapy until 8 cycles or until disease progression; group B--patients without clinical benefit in whom chemotherapy was stopped after 4 cycles. Clinical benefit was a composite of assessment of pain, ECOG performance status, weight and temperature. Clinical benefit required a sustained improvement in at least one parameter without worsening in any other. Of 97 evaluable patients 48 achieved stable disease. Of 22 pts. with SD clinical benefit performance status improvement was recorded in 17, pain relief in 14, improvement in body weight in 14 and temperature disappearance in 8 pts. Of 26 pts. with SD without clinical benefit, 7 were asymptomatic from beginning of the chemotherapy. No difference was detected in the survival between responders and SD clinical benefit pts. (p = 0.24), but there was significant difference between responders and SD pts. without clinical benefit (p = 0.0004). SD clinical benefit pts. had significant difference in survival in comparison to pts. with progressive disease (p = 5.1 x 10(-6)). The results of our study indicate that under category "stable disease" there are two different subpopulations of patients with quite different symptom response to chemotherapy, different time to progression and possible different survival.
