Locoregional pain treatment. Troubles and prospectives: antalgic radiotherapy.

Pain control in patients with cancer represents a significant aspect of radiation therapy practice. Radiation therapy is one of the most effective, and often the only, therapeutic option to relieve pain caused by nerve compression or infiltration by malignant tumor, pain from liver and bony metastases and it provides also successful palliation of dysphagia caused by oesophageal carcinoma and of pain due to pancreatic cancer. Various instruments are avaliable for pain evaluation but a valid methodology to assess the pain status in the patient with cronic cancer pain is still an important clinical problem. In this complex and wide scene this contribution wants to confirm the role of radiotherapy in cancer pain control, in paricular in bone metastases, and to involve the patient himself in the survey of radiation treatement response by a subjective evaluation of bone pain, elaborating a reliable and valid unidimensional method by which recording the self-rating of the patient's sensation. Materials and Methods For the subjective evaluation of pain caused by bone metastases we used an application form with which drawing information in the course of time in terms of: response to the treatment, duration of symptom relief and quality of life. Results Considering as cut-off a dose of 30 Gy, which is commonly considered the conventional treatment for bone metastases, the partial and complete response were, respectively, of 54% and 30% in the patients treated with dose higher than or equal to 30 Gy, and 60% and 20% in the ones treated with doses lower than 30 Gy. In the whole, in 84 patients, the global response was of 82%, in accordance with literature. Conclusion In this retrospective study, the analysis of patient's subjective experience confirmed the effectiveness of radiotherapy in reducing pain caused by bone metastases and in improving quality of life of the patient himself. Given the conflicting opinions on low-dose short-course radiotherapy versus prolonged or higher dose schedules on initial pain relief, we are going to define categories of homogenous patients on whom starting treatment schedules with the aim or of palliation of the symptom or of the functional restitutio, on the base of the expectation and the quality of life.

Preoperative chemoradiation with raltitrexed ('Tomudex') for T2/N+ and T3/N+ rectal cancers: a phase I study.

The use of raltitrexed ('Tomudex') as concomitant chemotherapy during preoperative radiotherapy in chemonaïve patients with stage II/III rectal cancer has been examined in this study and its recommended dose in conjunction with radiotherapy investigated. Forty-five Gray (Gy) of radiotherapy (1.8 Gy daily, 5 days per week) was delivered to the posterior pelvis, followed by a 5.4 Gy boost. Single doses of raltitrexed (2.0, 2.5 and 3.0 mg/m(2)) were administered on days 1, 19 and 38. Only 1 of the 15 patients entered experienced a dose limiting toxicity (DLT) (grade 3 leucopenia) at the 3.0 mg/m(2) dose level. The overall response rate was 80% (five complete responses, seven partial responses). These preliminary data suggest that raltitrexed is a well tolerated and effective treatment when combined with preoperative radiotherapy in patients with stage II/III rectal cancer. The recommended dose of raltitrexed for future phase II studies will be 3.0 mg/m(2).

Non-Hodgkin's lymphoma of the maxillary sinus in a patient with acquired immunodeficiency syndrome.

Non-Hodgkin's lymphoma (NHL) is one of the most common malignancies in patients infected with human immunodeficiency virus (HIV): it occurs 25-60 times more frequently in HIV-infected patients than in the general population. This neoplasm in acquired immunodeficiency syndrome (AIDS) patients is a highly aggressive tumour with a poor prognosis and tends to develop in extranodal sites, such as the central nervous system, digestive tract and bone marrow. NHL involving the paranasal sinuses is rare in HIV-infected patients, and is likely to be confused clinically and radiographically with sinusitis; moreover, its optimal treatment is currently uncertain. We present a case of NHL involving the left maxillary sinus in a patient with AIDS. The patient was treated with systemic chemotherapy (low dose-CHOP), but the malignancy did not respond. Subsequently, he was treated with local maxillary sinus irradiation which resulted in partial regression of the neoplasm and in decrease of local symptoms.

Phase I-II trial of concomitant continuous carboplatin (CBDCA) infusion and radiotherapy in advanced nonsmall cell lung cancer with evaluation for surgery: final report.

PURPOSE: The goal of this trial was to determine the maximum tolerable dose when carboplatin (CBDCA) was administered in continuous infusion concurrently with radiotherapy in patients with nonsmall cell lung cancer. METHODS AND MATERIALS: From October 1989 to July 1993, 54 patients were studied (male/female ratio: 44 to 10), median age was 62 years. Two patients had Stage II cancer, 22 had Stage IIIA, 24 had Stage IIIB, and 6 had Stage IV. Carboplatin was given for 96 h, starting at a dose of 30 mg/m2/day: 13 patients received 30 mg/m2/day (group A), 12 patients received 50 mg/m2/day (group B), 12 patients received 70 mg/m2/day (group C), 10 patients received 90 mg/m2/day (group D), and 7 patients 110 mg/m2/day (group E). The radiation dose was 50.40 Gy delivered to the target volume in 5.3 weeks. RESULTS: Fifty-three of 54 patients were evaluable for toxicity and 52 out of 54 for response. Toxicity (Miller score): Myelotoxicity: in groups A and B it was almost absent; in groups C and D it was moderate (leukopenia G1-2: 45.4% patients; trombocytopenia G1-2: 22.7%, G3: 9%; anemia G1-2: 9%); only in group E was it severe (leukopenia G1 and G3 16.6% respectively; trombocytopenia G3: 33.3%, G4: 16.6%; anemia G1-2: 50%). Nephrotoxicity was present only in one patient of group E and was Grade 3. Nausea and vomiting were related to CBDCA dose. One patient in Group E died of intractable toxicity 3 days after the end of infusion; then the study was closed. The limiting toxicity dose was shown to be 110 mg/m2/day given for 96 h. Clinical response rate: Twenty-six of 52 patients had major response, 24 had minor response, and only 2 patients had progression of disease. SURGERY: Twenty-one of 52 tumors were judged resectable: 18 patients had complete tumor resection, 1 had exploratory thoracotomy, and 2 patients refused surgery. Pathological response rate: Five patients had pathologic state T0 or Tis. CONCLUSIONS: These results indicate that the maximum tolerable dose of CBDCA infusion for 96 h is 90 mg/m2/day, and this schedule seems to produce an appreciable response rate. Therefore, we have started a Phase II trial, which will permit us to define the true efficacy of this schedule.

[Computerization experience in a day hospital of integrated radiochemotherapy].

INTRODUCTION: We report on a cost-effective easy-access software developed for the functional integration of the clinical records and history of oncologic patients with the management of the Day Hospital of the Radiotherapy Department of the University Hospital A. Gemelli, in Rome. MATERIAL AND METHODS: The software was designed to archive the clinical records and history of oncologic patients and the relative chemotherapy, to manage the examination scheduling, to draw up nursing files with the planned therapy and to make statistical analyses of the department activity. Five forms are available: the patient form, recording patient data; the admission form, recording the type of therapy (e.g., chemotherapy, tests, medical examinations, etc.), the relative cost and chemotherapy protocol, detailing for instance the type of drug; the nursing file, detailing chemotherapy schedule and the dilution of each drug; the menu, to select and retrieve any record. The minimum configuration requires a 386 Intel CPU, 4 Mb RAM and 4 Mb free on the hard disk. The software is the File Maker Pro 2.1 for Windows which can interact with Apple Macintosh computers. RESULTS: Since October, 1995, we have saved the clinical records of 272 oncologic outpatients (2415 entries in all), with a mean of 201/month. This computer system permitted us to save and retrieve data for both clinical and didactic purposes and to plan our activity. CONCLUSIONS: One year after it was implemented and used in clinical practice, the system is a cost-effective and user-friendly tool for the management of the Radiochemotherapy Day Hospital of our Radiotherapy Department.

[Diagnostic and therapeutic integration in non-small cell lung tumors: preliminary notes].

An interdisciplinary study relative to non-small cell lung cancers was activated in 1990 at the Policlinico A. Gemelli, Rome, Italy. A working group including radiologists, radiotherapists, oncologists, surgeons, respiratory physiopathologists and pathologists defined the goals to reach and the protocols to follow for staging, treatment, and follow-up. A hundred and ninety patients with non-small cell lung cancer were examined: 134 of them, who were in the initial or locally advanced phases, were considered, together with 6 patients with postoperative recurrences. Ninety-three cases were considered to be resectable and therefore operated: the extant 41, considered unresectable/slightly resectable, and the 6 with postoperative recurrences were started on combined chemo- and radiotherapy. Primary tumor (T) and lymph nodes (N) were staged by means of CT. In the evaluation of T in resectable patients, CT exhibited 78.5% agreement with pathology, with a tendency to understaging. In the evaluation of N, CT exhibited 62.4% agreement with pathology, once again with a tendency to understaging. Surgery was exploratory in 4.3% of cases only. Combined chemo- and radiotherapy in unresectable patients and in postoperative recurrences yielded > 50% response in 18/47 patients, that is 40.4% especially relative to the cases treated with carboplatinum in continual infusion. Eight of 18 responsive patients were considered to be resectable and therefore submitted to surgery: in 2 of them histology showed no neoplastic cells. This study, which is still in progress, is aimed at verifying its hypotheses and attaining its prefixed goals.

Primary mediastinal seminoma.

Two new cases of primary mediastinal seminoma are presented and 126 cases from the literature are analysed. Radiotherapy, alone or combined with surgery, is thought by some authors to be the treatment of choice and the role of chemotherapy is uncertain. We propose a classification by which it is possible to compare various therapeutic approaches and to establish their value.

Regional chemotherapy by a totally infusion pump preceding radiotherapy in advanced cervical carcinoma: a preliminary report.

The authors report the preliminary results of a prospective study on intra-arterial chemotherapy and radiotherapy of advanced cervix carcinoma. The drugs were delivered by a totally implanted Infusaid Model 400 pump and patients received cyclic therapy consisting of Cis-Platinum, Methotrexate and Bleomycin. The catheter tips were positioned during a laparotomy in the hypogastric arteries with sutures and the pump was implanted in a subcutaneous pouch in the abdomen. After chemotherapy all patients had radiotherapy. Five patients entered in the study. Preliminary results suggest that long-term intra-arterial infusion chemotherapy for the treatment of advanced cervix carcinoma is practical for many patients. Two of five patients, after intra-arterial chemotherapy and radiotherapy, had radical hysterectomy.

Elevated serum levels of creatine kinase BB in breast cancer.

Creatine kinase BB serum levels were evaluated by radioimmunoassay in patients with benign or malignant breast pathology. Elevated enzyme levels were observed in 6 out of 20 (30%) patients with primary breast cancer. After surgery the levels fell to normal values only in patients without nodal involvement. Six out of 28 (21%) patients with benign breast lesions and 4 out of 38 (13%) patients with metastatic breast cancer also showed increased levels of the enzyme. Most of the patients with high creatine kinase BB serum levels were found to have estrogen and progesterone receptor-positive tumors. These findings suggest that creatine kinase BB can barely be considered a marker of malignancy in breast pathology, but rather an indicator of hormone dependency in breast cancer.

Advanced carcinoma of the cervix treated by continuous pelvic arterial infusion with cytostatics and radiation therapy.

Regional chemotherapy by infusion of cytostatic drugs (methotrexate and adriamycin) into the hypogastric arteries has been used in 25 cases of advanced carcinoma of the cervix (IIIB and IV stage). A method for the percutaneous introduction of catheters into these arteries and their permanence for a period of time of 8-12 days is described. After chemotherapy there was such a satisfactory reduction in size of the tumour that patients could then be treated with radiotherapy and/or surgery.

Advances in the treatment of lung cancer: economic and organizational aspects.

The organizational optimization in radiotherapy tends to a correct balance of quality of service and containment of health care expenditure; this goal is necessarily correlated with the real potentialities available to each center while considering the possible clinical benefits for the patient. In lung cancer, outcomes achieved with radiation therapy are encouraging in terms of local control and survival when treatment is performed with the available modern technology whose costs from an exclusively economic analysis are shown to be still quite high. In an assessment focused on clinical outcomes, better local control, higher survival and improved quality of life represent tangible benefits: this has a positive impact on community costs and may represent a high priority goal for health care providers, yielding a benefit that can be quantified with the most recent analyses of health care economy.

Topical issues in the treatment of rectal cancer: economic and organizational aspects of concomitant radiochemotherapy.

Concomitant radiochemotherapy in patients with locally advanced rectal carcinoma has been shown to be useful in improving local control and survival in operated patients and in favoring sphincter preservation when administered before surgery. Together with the search for less toxic combinations, cost-analysis of radiochemotherapy has become topical also in consideration of new generation drugs. In this study the analysis was carried out by comparing the costs for 4 different combined modalities in the dual perspective of the payer (the National Health Service) and the provider (the Hospital). Based on their characteristic of treatment and innovative aspects, the following combinations were examined: external beam radiotherapy (ERT) 50.4 Gy + 5FU bolus; ERT 50.4 Gy + 5FU protracted infusion; ERT 50.4 Gy + 5FU continuous infusion, week 1 and 5; ERT 50.4 Gy+ Tomudex bolus. Costs were evaluated based on the frequency and type of specific services provided in therapeutic protocols: the positioning of central venous catheter, time of stay in day-hospital or hospital ward and the cost of drugs. Calculations were carried out based on an "ideal" patient of 1.7 sqm body surface. Costs were based on out patient rates, DRGs and the official drug list valid to September 1999. As for day-hospital costs afforded by the payer it is observed that the most expensive combinations are bolus and continuous infusion followed by protracted infusion; Tomudex, is the most economic. As for hospital costs afforded by the provider, it is observed that the most expensive combination is continuous infusion followed by protracted infusion, bolus administration and Tomudex. In conclusion, doctors are increasingly involved in the economic and organizational aspects of therapeutic decisions; however, the patient's needs should be kept in mind; apart from the therapeutic benefits, lower toxicity and ready use of treatments are amongst the patient's needs. The analysis of the patient's satisfaction is still lacking suitable means of evaluation, however it should be defined and carefully studied for an exhaustive evaluation of the impact of combined modality therapy.

Research trends in the treatment of colorectal cancer.

Colorectal carcinoma ranks second in incidence after lung cancer in males and breast carcinoma in females. Within the clinical research on this tumor, new molecules of antineoplastic agents and new combined modality treatments have been introduced. From the examination of ongoing protocols some trends can be identified: the interest in immunotherapy and genetic therapy, frequently tested in combination with chemotherapy; the effort at the optimization of the administration of antineoplastic agents in the most common sites of metastatic lesions by hepatic or intraperitoneal infusion; the trend to a more aggressive treatment of metastastatic lesions with hyperthermia and cryoablation as well with the combination of systemic therapy and surgery. As far as radiotherapy is concerned, the main goals of clinical research seem represented by the need to optimize combined modality therapy in T3-4 rectal carcinoma both in terms of pre- and postoperative radiotherapy timing as well as of the combination with adjuvant chemotherapy. There is a growing interest in new drugs which in the future may replace the conventional 5-fluorouracil in concurrent chemoradiation.
