A 78-year-old man was admitted to our hospital with dyspnea in June 1988, and diagnosed as having small-cell lung carcinoma by cytological findings of pleural effusion. He was treated three times with CAV (cyclophosphamide, doxorubicin, vincristine) therapy and a partial response was achieved. In March 1989, he was again admitted complaining of right dull hypochondralgia accompanied by enlargement of primary tumor in the right lower lobe of the lung and metastases to mediastinal and intraabdominal lymph nodes. Because it was an aged and recurrent case, he was treated with continuous five-day infusion of etoposide, 30 mg/m2/day and CDDP, 18.5 mg/m2/day. After the second course, subjective symptoms clearly disappeared and swelling of mediastinal and intraabdominal lymph nodes was markedly reduced on computed tomography. No severe side effects except for moderate myelosuppression, alopecia and nausea were observed. This regimen appears useful in the treatment of small-cell lung carcinoma in elderly patients.

An 87-year-old female was admitted with left chest pain and dyspnea in January 1989. The chest X-ray film revealed complete atelectasis of the left lung. Bronchoscopic observation revealed a tumor which was bleeding easily at left main bronchus. Cytological findings of the bronchial aspirates showed small cell lung cancer. Because she was old and had some complications, she was difficult to treat by standard combination chemotherapy. Only etoposide at 150 mg/day was administered orally for 3 days (first course). After the first course the whole lung atelectasis improved; and after the second course (etoposide at 150 mg/day for 4 days) the tumor of the left main bronchus disappeared under endoscopic examination. Malignant cells were not detected in the bronchial aspirates and biopsy specimens. No severe side effect except for alopecia and mild gastrointestinal symptoms such as nausea and vomiting was noted. Myelosuppression was not evident. This case suggested that etoposide administered orally is useful in the treatment of small cell lung cancer especially in elderly patients with complications.

The pharmacology, toxicity, and therapeutic effectiveness of etoposide (VP-16) given by the intrapleural route were examined in a phase I trial. Ten patients with malignant pleural effusion received 100, 150, or 225 mg/m2 VP-16 infused over 2 h into the pleural space after drainage of pleural fluid. The administration of VP-16 was tolerated well, with no local pain, increase in cough, dyspnea, or infection. Myelosuppression was mild at doses of 150 mg/m2 or less but severe at 225 mg/m2. Drug levels were followed in both plasma and pleural fluid for up to 12 h. Clearance of VP-16 from the pleural cavity was low at 2 ml/min m2. Peak pleural-fluid drug levels in patients receiving 225 mg/m2 exceeded 300 micrograms/ml, whereas peak drug concentrations in corresponding plasma samples obtained at the same time amounted to less than 10 micrograms/ml. Serial chest X-rays showed no disappearance of pleural effusion in nine evaluable patients. However, follow-up investigation of pleural fluid characteristics [carcinoembryonic antigen (CEA), lactic dehydrogenase (LDH), and cytologic examination] suggested some evidence of local therapeutic benefit.

Thirty-nine adults with solid tumors were treated on a Phase I study of menogaril administered i.v. once each week. Granulocytopenia was dose-limiting at a menogaril dose of 115 mg/m2/wk. Ten patients required delays in treatment of 1-4 weeks (median, 1 week) at some point during their treatment until they recovered from granulocytopenia. The average dose intensity possible on this schedule was at least 80% higher than that possible using a single-day or a five-times-daily schedule every 4 weeks. One patient developed infection while neutropenic, and only one patient developed thrombocytopenia. Dexamethasone appeared to reduce the degree of myelosuppression. Gastrointestinal toxicity was quite mild, and alopecia was uncommon. Arm vein phlebitis frequently followed menogaril administration, requiring the use of Hickman catheters (or equivalents). Two patients had myocardial infarcts while on treatment. It was unclear if the menogaril was in any way responsible. Reversible dyspnea and cough (with no evidence of congestive heart failure) were seen in some patients. Responses were seen in patients with gliomas, renal-cell carcinoma, and bladder carcinoma, and marked subjective improvement occurred in a single patient with prostate cancer. We plan to conduct a Phase II study in astrocytoma patients using a menogaril dose of 115 mg/m2/wk i.v.

A radiolabeled murine monoclonal antibody (T101) was used for imaging and therapy of six patients with cutaneous T cell lymphoma (CTCL). Radioimmunodetection was performed with a 5.6 to 13.1 mCi 131I-T101 preparation (9.6 to 10.5 mg). A therapeutic dose of 100.5 to 150.1 mCi 131I on 9.9 to 16.9 mg of antibody was administered to five patients, with subsequent retreatment following plasmapheresis in three patients at the time of disease progression. All patients responded to their initial therapy and two patients responded to retreatment. Regression of skin lesions and peripheral adenopathy was witnessed. All patients reported resolution of their chronic pruritus. The duration of response ranged from 3 weeks to 3 months. Acute toxicity included fevers, pruritus, and mild dyspnea in two instances. Myelosuppression was seen in patients receiving the 144.7 mCi, 145.0 mCi, and 150.1 mCi 131I-T101 doses. Radioimmunodiagnostic and therapy studies included gamma scintigraphy, plasma, urinary, and wholebody antibody clearances, and biodistribution determined from skin, bone marrow, and liver biopsies. Immunologic studies included immunoperoxidase staining of target tissues, immunofluorescent flow cytometric analysis on peripheral blood and bone marrow, assays for serum blocking factors, determination of a human antimouse antibody (HAMA) response, and quantitation of circulating T101 levels. These preliminary data suggest that 131I-T101 has therapeutic potential in CTCL and that myelosuppression will be the limiting toxicity.

The aim of this study was to assess the efficacy and toxicity of intensive chemotherapy, administered without dose reduction, with cranial and thoracic radiotherapy given when possible as a single fraction in small cell lung cancer. 87 patients were eligible on the basis of good performance status, normal or near normal biochemistry and clinical staging, 73 limited and 14 extensive stage, computed tomography scanning was not mandatory. Six cycles of carboplatin, ifosfamide and etoposide with vincristine on day 15 at 4 weekly intervals were planned. Dosages were not reduced in response to myelosuppression. Prophylactic cranial irradiation (PCI) as a single fraction after the first cycle and thoracic irradiation (when possible as a single fraction) following the third cycle were delivered. Seventy-two per cent of patients completed the protocol. Complete response rate was 55% and 26% of patients had a partial response. The median nadirs of neutropenia were 0.5 x 10(9)/l and thrombocytopenia 14 x 10(9)/l, with 6% probable treatment-related deaths. Performance status and dyspnoea improved markedly to normal or near normal levels following the second course. Brain metastases occurred in 13% of patients. The median survival was 16.2 months with a 2-year survival of 31% (95% confidence interval, 24-41%) for a minimum follow-up of 26 months. These results compare favourably with other combined modality studies, using multiple radiotherapy fractions with cisplatin-based combinations and dosage reduction for patients staged in more anatomical detail. The toxicity spectrum and efficacy data could lead to the use of this chemotherapy regimen with haematopoietic growth factors and, in the future, peripheral blood progenitor cell rescue.

A combination of cisplatin (80 mg/m2) and methotrexate (200 mg bolus and 400 mg as a 12-hour infusion) was given to 40 patients who developed local recurrence of cervical cancer after radiotherapy. A maximum of six courses was given at monthly intervals. Twenty-five of the forty (63%) evaluable patients responded, of which 4 (10%) responded completely. A symptomatic response, with reduction of pain, leg oedema, vaginal discharge and breathlessness was seen in 27 (68%) of patients. The median survival of all patients was 11 months. Toxicity was moderate; WHO grade 1 or greater was observed in 83% for nausea and vomiting, 67% for myelosuppression and 47% for mucositis. This combination chemotherapy is active in the treatment of recurrent cervical cancer and a modification of this regimen is currently being assessed as neo-adjuvant therapy in patients with Stage IIB-IVA cervical cancer.

The aim of this study was to ameliorate the toxicity of the etoposide, doxorubicin and cisplatin (EAP) regimen and to investigate the feasibility of dose escalation, using the molgramostim form of granulocyte macrophage-colony stimulating factor (GM-CSF) 10 micrograms/kg/day s.c. into the regimen. The design of the trial allowed for amended scheduling of the agents in the event of suboptimal results. Initially the regimen comprised etoposide 120 mg/m2, days 1-3, doxorubicin 40 mg/m2, day 1, and cisplatin 40 mg/m2, days 2 and 8. GM-CSF was begun on day 4 and continued until recovery of granulocyte counts. Courses were repeated every 21 days. 3 patients were treated at these doses. 5 patients received escalated doses (etoposide 180 mg/m2; doxorubicin 60 mg/m2; cisplatin 60 mg/m2) on this schedule; 4 out of 5 had intolerable myelosuppression (grade IV neutropenia or thrombocytopenia lasting > or = 7 days). These results prompted the administration of the day 8 cisplatin dose on day 3, with GM-CSF beginning on day 4. At the lowest doses of each agent (etoposide 120-doxorubicin 40-cisplatin 40), 3 of 6 patients had intolerable myelosuppression, and 3 patients had febrile neutropenia. Dose escalation of all of the drugs to etoposide 180 mg/m2, doxorubicin 60 mg/m2, cisplatin 60 mg/m2 resulted in documented infections in 4 out of 4 patients. GM-CSF toxicity included rash, dyspnoea, arrhythmias and pericardial effusions. The conclusion was that the use of GM-CSF does not permit escalation of drug doses on either schedule of EAP administration, and that these results do not support the combined use of GM-CSF and EAP.

Twenty-nine patients with persistent, recurrent and/or metastatic squamous cell carcinoma of the head and neck were treated daily for five days at three-week intervals with topotecan 1.5 mg/m2. Four patients received prior chemotherapy, 23 prior surgery and 29 prior radiation therapy. Of the 29 eligible patients, 8 patients were not evaluable for response and were assumed to be non-responders. Of the remaining 21 evaluable patients, there were zero responses (0%, 95% confidence interval [0,.12]). The most common toxicities were myelosuppression, dyspnea and malaise/fatigue/lethargy. Topotecan has limited activity in advanced head and neck cancer with this dose and schedule.

Approximately one half of prescribed radiotherapy is given for palliation of symptoms due to incurable cancer. Distressing symptoms including pain, bleeding, and obstruction can often be relieved with minimal toxic effects. Painful osseous metastasis is common in oncologic practice. Ninety percent of patients with symptomatic bone metastases obtain some pain relief with a lowdose, brief course of palliative radiotherapy. One half of the responding patients may experience complete pain relief. A single dose of 800 cGy in the setting of painful bone metastasis may provide pain control comparable to more protracted treatment at a higher dose of radiation. Patients with lytic disease in weight-bearing bones, particularly in the presence of cortical destruction, should be considered for prophylactic surgical stabilization of their condition. Routinely a brief, fractionated course of radiotherapy is given postoperatively. Pain due to multiple bone metastases uncontrolled by analgesics can be managed with single doses of halfbody irradiation. Doses of 600 cGy delivered to the upper half-body (above the umbilicus) and 800 cGy to the lower half-body (from the umbilicus to the middle of the femur) will provide some pain relief in 73% of patients. Half-body techniques have been investigated as prophylactic treatment, as a complement to local-field irradiation, and as fractionated rather than singledose therapy. Although intravenous administration of strontium 89 has been associated with myelosuppression, this treatment has been shown (a) to relieve pain due to bone metastasis and (b) to delay development of new painful sites. Recent data from phase III trials demonstrated that bisphosphonates have a role in reducing skeletal morbidity due to bone metastasis. Bone pain was reduced, and the incidence of pathologic fracture and the need for future radiotherapy was decreased. Radiotherapy relieves clinical symptoms in 70% to 90% of patients with brain metastases. Brief treatment schedules (e.g., 2000 cGy in five fractions over 1 week) are as effective as more prolonged therapy. Patients with solitary brain metastasis and no extracranial disease or controlled extracranial disease should be considered for surgical resection, because phase III data indicate enhanced survival with such an approach. Whole-brain radiotherapy is routinely administered postoperatively. A phase III study is examining the impact of accelerated fractionated doses of radiotherapy (two treatments per day) on survival of patients with brain metastases. Stereotaxic radiosurgical treatment is becoming increasingly available and permits delivery of radiation to metastatic intracranial tumor with minimal exposure of normal surrounding brain This treatment is most commonly used at the time of a solitary recurrence of disease in patients who previously received whole-brain radiotherapy. A role for this modality in newly diagnosed brain metastases remains to be defined. Chest symptoms are common in patients with locally advanced lung cancer and are effectively palliated with one 1000 cGy or two 850 cGy one fraction doses of radiation to the thoracic inlet and mediastinum. Chest pain and hemoptysis are more effectively palliated than cough and dyspnea. In patients with stage III cancer there is no compelling evidence that radiotherapy confers a survival advantage, and it may be reasonable to administer thoracic radiotherapy only when the patient has significant symptoms and the goal is to achieve control of these symptoms. Approximately 75% of the cases of superior vena cava syndrome are due to lung cancer, and small-cell lung cancer is the most common histologic type. A histologic diagnosis should be obtained before treatment is started, because detection of lymphoma or small-cell carcinoma would necessitate systemic therapy. Eighty percent of the patients with vena cava syndrome due to malignant disease achieve symptom relief with a brief, fractionated, palliative course of rad
