We report the case of a patient with a rare miliary variant of osteosarcoma associated with symptomatic hypocalcemia and review the literature regarding the pathogenesis of multifocal osteosarcoma, treatment options, and the associated hypocalcemia.

Eleven randomly hydrated patients with metastatic malignancies received iv bolus chemotherapy. Serial observations of plasma antidiuretic hormone (ADH), serum osmolality, blood pressure, and presence of nausea or emesis were made over the next 3-4 hours. Group 1 (four patients) had no nausea or emesis and no change in ADH, osmolality, or mean blood pressure. Group 2 (seven patients) had nausea and emesis following chemotherapy, with an increase in mean ADH from a baseline level of 5.53 pg/ml to a peak after emesis of 33.83 pg/ml. Group 2 had no significant increase in osmolality or decrease in mean blood pressure before emesis. ADH levels increased 0-40 minutes before emesis and peaked 28-115 minutes (mean, 66) after emesis. Emesis caused by chemotherapy agents is associated with rapid, significant increases in plasma ADH levels, independent of changes in osmolality or blood pressure.

Fifty-six patients with small cell carcinoma of the lung were treated with a two-cyclic induction course of hexamethylmelamine, vincristine, doxorubicin, and cyclophosphamide. Patients with limited disease (LD) who responded and patients with extensive disease (ED) who had a complete response received prophylactic whole-brain radiotherapy, as well as radiotherapy to thoracic and abdominal sites of disease. Concurrently with radiotherapy, consolidation chemotherapy was given with doxorubicin, cyclophosphamide, methotrexate, and etoposide. The complete response rate was 35% for ED patients and 68% for LD patients. The median survival time for complete responders was 54 weeks for ED patients and 65 weeks for LD patients. The toxicity of the program was moderate, and the effectiveness was comparable to that of other reported combined-modality treatment programs.

A prospective randomized trial has compared cyclophosphamide (CTX) with CTX plus cis-diamminodichloroplatinum (DDP) as the initial chemotherapy for advanced ovarian carcinoma. A secondary randomization compared the addition of BCG treatment to either chemotherapy. The addition of DDP had no measurable impact on survival, but a small survival trend favoring BCG-treated patients was noted (P less than 0.08). Toxicity from BCG treatment was insignificant, but the addition of DDP increased both early nausea and vomiting and later hematologic toxicity. There were three long-term complete remission patients, and these all came from the group of six patients with pretreatment residual disease less than 2 cm. A univariate analysis of pretreatment prognostic factors indicated significantly better prognosis (P less than 0.02) for patients with no palpable tumor, platelet count less than 400,000/mm3, residual tumor less than 2 cm, resting pulse less than 91/min. and LDH less than 250 U/L. The authors conclude that for patients with large (greater than 2 cm) residual disease, there is no compelling evidence that initial combination therapy is superior to aggressive single alkylating agent treatment.

Gingival metastases from non-oral malignancies are very uncommon. The case is presented of a man with rectal adenocarcinoma, whose first clinical evidence of metastatic disease was a gingival metastasis. Although the prognosis of patients with gingival metastases is felt to be poor, prompt initiation of appropriate therapy may afford significant palliation. A 20-year literature review of uncommon metastatic sites for rectal adenocarcinoma and non-oral malignancies which can metastasize to gingiva is briefly presented. Gingival metastasis should be included in the differential diagnosis of a gingival lesion in a patient with prior or current malignancy.

Two cases are presented which suggest that pyridoxine injected into a Mitomycin-C extravasation site may slow or prevent necrosis, and may decrease the pain associated with the chronic ulceration of extravasation.

From 1950 through 1975, 671 patients with malignant major salivary gland neoplasms were referred to M. D. Anderson Hospital and Tumor Institute. Thirty-six patients with advanced local or metastatic disease subsequently underwent 62 evaluable trials with a variety of chemotherapeutic agents, either alone or in combination. Six patients achieved a partial response, with a median duration of 3 months. Ten additional patients had stable disease for 2 or more months. Anthracyclines appeared to be the most effective agents in this study, with three partial responses of six evaluable trials. The longest partial response (10 months) occurred in a patient receiving combination chemotherapy plus BCG immunotherapy. Pulmonary metastases were most commonly responsive to chemotherapy. The median intervals from diagnosis to death or to last follow-up and from initiation of chemotherapy to death or to last follow-up were 30 months and 6 months, respectively. Further therapeutic trials are necessary before response rates to single chemotherapeutic agents or combinations can be accurately assessed. In view of the poor prognosis of patients with recurrent disease, postoperative adjuvant studies with chemoimmunotherapy in patients with a high risk of recurrence are planned.
