Factors determining the place of palliative care and death of cancer patients.

Factors determining the place of palliative care and death were studied by interviewing 40 patients using a semi-structured questionnaire. The 86 interviews assessed showed that both emotional and somatic factors played a part in the determination of whether patients were transferred and of their place of death. Emotional factors were mentioned in 41% as being of importance, and physical factors in 32%. Material and financial factors are probably underestimated owing to the methodology.

Methylene blue in the treatment and prevention of ifosfamide-induced encephalopathy: report of 12 cases and a review of the literature.

Ifosfamide is an alkylating agent used in the treatment of a variety of solid tumours. Ten to 15% of patients treated with ifosfamide develop an encephalopathy. Methylene blue (MB) may be used in the treatment of this encephalopathy. The purpose of this study was to evaluate the neuroprotective effect of MB in these patients and to review the literature. Between 1993 and 1997, 52 patients (age 16-77 years) with solid tumours were treated with ifosfamide in dosages ranging from 3 to 5 g m(-2) q3w when given in combination schedules and up to 12 g m(-2) q4w when given as a single agent. Twelve patients developed central nervous system (CNS) depression, defined as National Cancer Institute Common Toxicity Criteria (NCI-CTC) neurocortical toxicity grade 2 or higher. Eight were treated with MB at a dose of 6 x 50 mg day(-1) intravenously (i.v.). Four recovered fully within 24 h, two recovered partially after 24 h and completely after 48 h while two recovered only after 72 h. Four patients did not receive MB and all recovered only after 48 h. Three patients received prophylaxis with MB at a dose of 4 x 50 mg day(-1) i.v. for the subsequent chemotherapy cycles. Two developed milder encephalopathy; one had no CNS depression at all. We conclude that MB is an effective treatment for ifosfamide-induced encephalopathy. Our findings suggest that it may also be used as a prophylactic agent.

Thoracic wall prosthesis prevents deep invasion by non-small-cell lung cancer.

Chest wall invasion is found in 5% of patients with non-small-cell lung cancer. Treatment for localized non-small-cell lung cancer consists of surgical resection and/or radiotherapy. We report a patient with lung cancer who had a local relapse after a reconstruction of the thoracic wall with a soft-tissue patch. Chemotherapy was given before reresection of the local relapse. Postoperative radiation therapy was performed. Twenty-one months after treatment for recurrent disease, the patient remains in complete remission. The history of this patient shows that a soft-tissue patch may prevent local tumor invasion. A review of the literature is given.

Cytomegalovirus colitis after administration of docetaxel-5-fluorouracil-cisplatin chemotherapy for locally advanced hypopharyngeal cancer.

We present the case of a patient with a locally advanced hypopharyngeal carcinoma who developed a severe cytomegalovirus (CMV) colitis after his first chemotherapy course with 5-fluorouracil (5-FU), docetaxel and cisplatin. The most probable cause of his CMV colitis is the impaired immunity during a phase of neutropenia after the chemotherapy. Although there was amelioration of the colitis and clinical status after treatment with ganciclovir, the patient later deteriorated and died due to recurrent bacterial infections. This is the third reported case of CMV colitis treated with ganciclovir in a patient with a solid tumour. It is the first report of CMV colitis after docetaxel containing chemotherapy. Although CMV colitis is most frequently observed in immunosuppressed patients such as those with acquired immune deficiency syndrome (AIDS), transplants and corticosteroid treatment, it has also been reported in less immunosuppressed (elderly, malnourished,...) and even non-immunosuppressed patients. CMV infection should therefore be included in the differential diagnosis of GI disease in all patients, and when suspected, the clinician should pursue appropriate diagnostic and therapeutic interventions.

Docetaxel and cisplatin: an active regimen in patients with locally advanced, recurrent or metastatic squamous cell carcinoma of the head and neck. Results of a phase II study of the EORTC Early Clinical Studies Group.

BACKGROUND: Docetaxel and cisplatin are among the most active antitumor agents in head and neck cancer, and phase I studies found the combination of the two drugs to be feasible. The EORTC ECSG performed a multicenter phase II study in patients with locally advanced, recurrent or metastatic squamous cell carcinoma of the head and neck to evaluate the antitumor efficacy and toxicity of this combination. PATIENTS AND METHODS: Eligibility criteria included written informed consent, a WHO performance status < 2, life expectancy of > 12 weeks, and adequate bone marrow, liver and renal function. Neoadjuvant pretreatment with cisplatin-based chemotherapy or prior radiotherapy were allowed. Patients were ineligible if pretreated with taxoids, had CNS involvement, concurrent malignancy, peripheral neuropathy, or no measurable disease. Treatment consisted of docetaxel 100 mg/m2 (one-hour i.v. infusion), followed by cisplatin 75 mg/m2 (three-hour i.v. infusion), repeated every three weeks. Supportive care included hydration, 5HT3-antagonists, and corticosteroids. RESULTS: Forty-four patients (median age 55 years, range 35-76) entered the trial; 41 patients were eligible, 164 cycles of treatment were evaluable for toxicity, and 31 patients for response. Fourteen patients had undergone prior surgery, 15 had received radiotherapy, and five had had chemotherapy. A median number of four treatment cycles (range 1-6) was given. Hematologic and non-hematologic toxicities were common, but hypersensitivity reactions and fluid retention were very infrequent due to corticosteroid prophylaxis. Four patients were taken off the study due to toxicity, and one toxic death occurred due to pneumonia. Among 41 eligible patients, objective responses as confirmed by independent review included six complete remissions and 16 partial remissions, resulting in an overall response rate of 53.7% (95% confidence interval: 37.4%-69.3%). Responses occurred in locally advanced, recurrent and metastatic disease, both in pre- and non-pretreated patients. Of 22 evaluable, non-pretreated patients with locally advanced or metastatic disease, five achieved complete responses, and 14 partial responses. Observed among nine evaluable pretreated patients with locally advanced or metastatic head and neck cancer were one complete response and two partial responses. CONCLUSION: The combination of docetaxel and cisplatin is feasible and active in locally advanced, recurrent, and metastatic squamous cell carcinoma of the head and neck.

Bilateral pulmonary resection for lung metastases: report of two cases.

Resection of bilateral pulmonary metastases is exceptional. However, in carefully selected patients extensive resections might be successfully performed. We report two patients who underwent a pneumonectomy and excision of pulmonary metastases in the other lung, via a left wedge resection for patient 1 and left segmentectomy for patient 2. Resections were carried out for metastases of a malignant fibrous histyocytoma and for a teratocarcinoma. Both patients are still alive 9 months and 4 years after their last metastasectomy, respectively.

Role of red blood cells in pharmacokinetics of chemotherapeutic agents.

After oral or parenteral administration of chemotherapeutic agents, these drugs are transported to the tissues by the blood in different fractions: plasma water, plasma proteins or cells. In this review, the role of the red blood cell in storage, transport and metabolism of different anti-cancer drugs is described.

KW-2149-induced pulmonary toxicity is not prevented by corticosteroids: a phase I and pharmacokinetic study.

KW-2149 is a new, semisynthetic, C-7-N-Substituted, mitomycin C analog showing antitumor activity both in vitro and in vivo, equal or superior to mitomycin C. In a phase I study, KW-2149 was administered as an i.v. bolus injection every 21 days and at a dose of 100 mg/m2 pulmonary toxicity was dose limiting. Animal studies have indicated since that KW-2149-induced pulmonary toxicity can be prevented by pretreatment with corticosteroids. This paper presents the results of a further phase I study of KW-2149 with corticosteroid pretreatment. Patients were treated with oral dexamethasone 8 mg every 12 h, starting 24 h before KW-2149 administration, for 5 days. KW-2149 was given as an i.v. bolus injection every 21 days. Seventeen patients were treated with a total of 48 courses. Six patients received 60 mg/m2 and 11 patients 75 mg/m2. Two courses were not evaluable for toxicity. Significant lung toxicity was observed in at least three patients treated with a dose of 75 mg/m2 KW-2149 and pulmonary toxicity was therefore considered the dose-limiting toxicity at 75 mg/m2. No other important side effects were noted. One partial response was observed in a patient with colorectal cancer. Pretreatment with dexamethasone failed to suppress KW-2149-induced lung toxicity.

Rebound thymic hyperplasia after chemotherapy in a patient treated for pulmonary metastases.

A 38-year-old patient presented with an anterior mediastinal mass after chemotherapeutic and surgical treatment for lung metastases from a malignant histiocytoma. Because of the risk for tumour recurrence the thymic mass was resected. Thymic hyperplasia was found on pathological examination. In this case thymic hyperplasia is a rebound phenomenon aflcer chemotherapy. It appears to atrophy during the administration of chemotherapy and regrow afterwards. Surgical resection provides the definitive diagnosis and treatment.

Late peritoneal metastasis in a patient with osteosarcoma.

A 19-year-old man with a high-grade osteosarcoma of the femur, treated with neoadjuvant chemotherapy, surgery, and adjuvant chemotherapy suffered from lung metastases 15 months after diagnosis. They were resected. Thirteen months later, he had vague abdominal complaints which, after analysis, proved to be caused by peritoneal metastasis. A review of the literature, possible physiopathological mechanisms of increased occurrence of unusual metastases and the role of bone scintigraphy in the follow-up of patients with osteosarcoma are discussed.

Phase I study on docetaxel and ifosfamide in patients with advanced solid tumours.

Docetaxel and ifosfamide have shown significant activity against a variety of solid tumours. This prompted a phase I trial on the combination of these drugs. This phase I study was performed to assess the feasibility of the combination, to determine the maximum tolerated dose (MTD) and the side effects, and to propose a safe schedule for further phase II studies. A total of 34 patients with a histologically confirmed solid tumour, who were not pretreated with taxanes or ifosfamide and who had received no more than one line of chemotherapy for advanced disease were entered into the study. Treatment consisted of docetaxel given as a 1-h infusion followed by ifosfamide as a 24-h infusion (schedule A), or ifosfamide followed by docetaxel (schedule B) every 3 weeks. Docetaxel doses ranged from 60 to 85 mg m(-2) and ifosfamide doses from 2.5 to 5.0 g m(-2). Granulocytopenia grade 3 and 4 were common (89%), short lasting and ifosfamide dose dependent. Febrile neutropenia and sepsis occurred in 17% and 2% of courses respectively. Non-haematological toxicities were mild to moderate and included alopecia, nausea, vomiting, mucositis, diarrhoea, sensory neuropathy, skin and nail toxicity and oedema. There did not appear to be any pharmacokinetic interaction between docetaxel and ifosfamide. One complete response (CR) (soft tissue sarcoma) and two partial responses (PRs) were documented. A dose of 75 mg m(-2) of docetaxel combined with 5.0 g m(-2) ifosfamide appeared to be manageable. Schedule A was advocated for further treatment.

Determination of compatibility and stability of drugs used in palliative care.

BACKGROUND: Drugs for symptom control in the terminal phase of palliative patients may be used in pump systems. OBJECTIVE: To investigate the compatibility and stability of solutions of morphine hydrochloride, haloperidol, metoclopramide hydrochloride, atropine sulphate, butylhyoscine bromide and ranitidine hydrochloride, which may be used together under such circumstances. METHOD: Solutions of the drugs were exposed to ambient light at a temperature of 20 +/- 5 degrees C and +/- 31 degrees C for 24 h and 7 days and the solutions studied by ultraviolet spectrophotometry. RESULTS: The combination of haloperidol or metoclopramide hydrochloride with different concentrations of morphine hydrochloride seemed to be compatible and stable. The concentration of atropine sulphate or butylhyoscine bromide could not be determined by the study method, but morphine hydrochloride seemed to be stable. The combination of ranitidine hydrochloride and morphine hydrochloride showed a change in colour after 7 days. CONCLUSION: The results suggest that the combination of different concentrations of morphine hydrochloride with haloperidol, metoclopramide hydrochloride, atropine sulphate, butylhyoscine bromide or ranitidine hydrochloride do not affect their stability when stored for 7 days up to 30 degrees C under the influence of ambient light. However, more robust stability-indicating methods are required to confirm these results. The proposed method is more useful for identifying combinations that are clearly incompatible than to identify those that are compatible.

Update on the taxoids and other new agents in head and neck cancer therapy.

Both paclitaxel and docetaxel have shown activity when used as a single agent in patients with squamous cell carcinoma of the head and neck (SCCHN). Combinations of both drugs with platinum derivatives and antimetabolites have been tested in patient populations with encouraging results, but some have exhibited considerable toxicity. It is unknown as yet whether such combinations are in any way superior to the standard platinum-based regimens. Intensive weekly schemes of taxoids and platinum compounds alone or in combination seem possible and deserve further study. Other agents such as vinorelbine, ifosfamide, thymetaq, trimetrexate, gemcitabine and topotecan showed variable activity in patients with SCCHN, but their role is still questionable. Following the optimistic view on the role of chemoradiation, combinations of paclitaxel (with or without carboplatin) with radiotherapy were studied, and the results seem feasible and promising.

Phase III trial of modulation of cisplatin/fluorouracil chemotherapy by interferon alfa-2b in patients with recurrent or metastatic head and neck cancer. Head and Neck Interferon Cooperative Study Group.

PURPOSE: In preclinical experiments, interferon alfa modulates the anticancer activity of fluorouracil (5-FU) and cisplatin (CDDP). To test this effect clinically in patients with recurrent or metastatic head and neck cancer (RMHNC), a multicenter randomized controlled trial with CDDP and 5-FU with or without interferon alfa-2b (IFNalpha) was performed. PATIENTS AND METHODS: Eligible patients had histologically confirmed RMHNC; a good performance status; measurable disease; adequate bone marrow, hepatic, and renal function; no prior chemotherapy for recurrent or metastatic disease; only one chemotherapy regimen administered with previous local therapy; and a treatment-free interval of at least 3 months following previous local therapy. Patients were randomized and stratified according to treatment center, and prior radiotherapy and chemotherapy. The treatment regimen consisted of CDDP 100 mg/m2 on day 1 and 5-FU 1,000 mg/m2/d by continuous infusion for 96 hours (days 1 to 4), without (arm A) or with (arm B) IFNg alpha 3 x 10(6) U/d subcutaneously on days 1 to 5. Cycles were repeated every 21 days. RESULTS: One hundred twenty-two patients were entered on each arm. The response rate (RR) was similar in both arms (arm A: complete response [CR] 10.7%, partial response [PR] 36.4%; arm B: CR 6.8%, PR 31.6%) (.70 < P < .50). There was no difference in median survival between the two arms (arm A 6.3 months v arm B 6.0 months; P = .49). Anorexia, fever, leukopenia, and thrombocytopenia grade III to IV were significantly more frequent in the IFNalpha arm. CONCLUSION: Modulation of CDDP and 5-FU with IFNalpha as used in this study does not improve the RR or the median survival in patients with RMHNC. Patients on both study arms had a poor prognosis, which indicates the need for novel therapies.

Docetaxel and ifosfamide in patients with advanced solid tumors: results of a phase I study.

Docetaxel is a new antimicrotubule agent that has been shown to be active against a variety of solid tumors. Ifosfamide is an alkylating drug that has demonstrated activity against non-small cell lung cancer, testicular cancer, breast cancer, and soft tissue sarcoma. This phase I study of the combination of these drugs was performed to assess the feasibility of using the two agents together, to determine the maximum tolerated dose and the side effects, and to propose a safe schedule for further phase II studies. Thirty-four patients with histologically confirmed solid tumors who had not been treated previously with taxanes or ifosfamide and who had received no more than one line of chemotherapy for advanced disease were entered into the study. Treatment consisted of docetaxel given as a 1-hour infusion followed by ifosfamide as a 24-hour infusion (schedule A), or ifosfamide followed by docetaxel (schedule B) every 3 weeks. Docetaxel doses ranged from 60 to 85 mg/m2 and ifosfamide doses from 2.5 to 5.0 g/m2. Grades 3 and 4 granulocytopenia were observed in 89% of courses and appeared to be of short duration and related to the ifosfamide dose. Febrile neutropenia and sepsis occurred in 17% and 2% of courses, respectively. Severe anemia and thrombocytopenia were uncommon. Nonhematologic toxicities were mild to moderate, and included alopecia, nausea, vomiting, mucositis, diarrhea, sensory neuropathy, skin and nail toxicity, hypersensitivity reactions, and edema. Schedule B appeared to induce more gastrointestinal toxicity than schedule A. One complete response in soft tissue sarcoma and two partial responses, one in cancer of unknown primary and the other in non-small cell lung cancer, were documented. The dose-limiting toxicity for schedule A was neutropenic fever at a dose of 85 mg/m2 docetaxel and 5 g/m2 ifosfamide. The dose-limiting toxicity for schedule B was neutropenic fever at a dose of 75 mg/m2 docetaxel and 4 g/m2 ifosfamide. A dose of 75 mg/m2 docetaxel combined with 5 g/m2 ifosfamide according to schedule A can be recommended for further studies.
