Rectal adenocarcinoma with germ cell elements treated with chemotherapy.

A patient with adenocarcinoma of the rectum containing germ cell elements in the form of endodermal sinus tumor and choriocarcinoma is described, believed to be the first such tumor reported in the literature. The serum levels of alpha-fetoprotein and human chorionic gonadotropin were markedly elevated. The source of the markers was localized to the neoplastic tissue by the immunoperoxidase technique. The patient developed extensive hepatic metastases thought to be due to choriocarcinoma for which she received chemotherapy. One wk after commencing treatment a massive fatal hepatic hemorrhage occurred.

A randomised trial of dexamethasone, lorazepam and prochlorperazine for emesis in patients receiving chemotherapy.

To define further the place of dexamethasone in antiemetic combinations, lorazepam, prochlorperazine and placebo (LP) were compared with lorazepam, prochlorperazine and dexamethasone (DLP) in a randomised, double-blind, crossover study. Both patient and observer assessments were documented in 84 patients receiving both cisplatin and non-cisplatin chemotherapy. The addition of dexamethasone significantly reduced the severity of nausea (P = 0.002) and vomiting (P less than 0.0001), duration of nausea (P = 0.01) and vomiting (P = 0.002) and the number of vomiting episodes (P = 0.003). DLP was the superior regimen in subsets of patients receiving cisplatin and the non-cisplatin chemotherapy. The improvements produced by the dexamethasone regimen were large and of major benefit to our patients. Patients documented significantly improved tolerance to chemotherapy with DLP courses (P = 0.0006). Overall, significantly more patients preferred DLP (P less than 0.0001). Patient assessments produced results similar to observer assessments but gave a broader understanding of their experience. The addition of dexamethasone to prochlorperazine and lorazepam significantly improved our patients' experience while receiving chemotherapy.

A phase II trial of cyclophosphamide, methotrexate, 5-fluorouracil, and prednisolone rapidly alternating with doxorubicin and vincristine (CMFP/AV) in advanced breast cancer.

Sixty-seven patients with advanced breast cancer were prospectively entered into a Phase II trial of cyclophosphamide 100 mg/m2 orally on days 1-14, methotrexate 40 mg/m2 intravenously (i.v.) on day 1, 5-fluorouracil 600 mg/m2 i.v. on day 1, and prednisolone 40 mg/m2 orally on days 1-14 (CMFP) rapidly alternating with doxorubicin 25-30 mg/m2 i.v. on day 8 and vincristine 1.4 mg/m2 i.v. on day 8 (AV). Complete responses (CR) were seen in 7 patients, partial responses (PR) in 25 (CR + PR, 48%), stable disease in 24, and progressive disease in 9. The median time to disease progression was 9.8 months, and the median survival 19.4 months. Neutropenia was the major toxicity with WHO grade 3 or 4 neutropenia in 50% of patients. CMFP/AV is a well-tolerated, effective regimen in advanced breast cancer but does not appear to be superior to CMFP alone.

Subxiphoid partial pericardiectomy with or without sclerosant instillation in the treatment of symptomatic pericardial effusions in patients with malignancy.

Twenty-two patients with malignant pericardial effusions were treated with subxiphoid partial pericardiectomy between 1984 and 1989. Thirteen patients also had a sclerosing agent instilled intrapericardially. Tamponade was relieved by pericardiocentesis before administration of general anesthesia. In 18 patients (82%), the effusions were controlled for longer than 30 days, and two patients died before 30 days without effusion. There were two recurrences at 1.5 and 7 months. There was one death due to hemorrhage from a laceration in a heavily infiltrated pericardium, and one patient had persistent dyspnea after the procedure. Complications included transient atrial arrhythmias (two patients), chest pain after sclerosant instillation (three patients), and fever greater than 37.5 degrees C after sclerosant (five patients). The survival range was 0.1 to 18 months (median, 5 months). Subxiphoid partial pericardiectomy with or without intrapericardial sclerosant is a safe and efficacious treatment for malignant pericardial effusions.

Extradural malignancy simulating brachial neuritis.

A 57 year old man is described who presented with symptoms and signs suggestive of brachial neuritis. Sparing of the serratus anterior both clinically and on electromyography suggested that the lesion was in the brachial plexus, thus supporting the diagnosis. Subsequent investigation showed an extradural tumour at C5-C6 level. Sparing of serratus anterior does not definitively localize the pathology as distal to the nerve roots.
