The aim of this study was to determine the prognostic factors for local failure and cause specific survival in differentiated thyroid carcinoma and the impact of surgery, radioiodine, and external beam radiation therapy (RT) when used as part of the initial management. ⋯ The prognostic factors for differentiated thyroid carcinoma have been clearly identified. Initial total thyroid ablation with total thyroidectomy and radioiodine was associated with a lower rate of local relapse, although CSS was unaffected. Many patients at risk for local recurrence received postoperative RT, which did not significantly affect the risk of local relapse or CSS in the entire group. A beneficial effect of RT was demonstrated in the subgroup of patients with papillary tumors and microscopic residuum. Patients with postoperative macroscopic residual disease appeared to benefit from RT (with or without radioiodine). A Phase III trial involving patients at high risk for local recurrence is required to assess the potential benefit of RT.

A 59-year-old male developed intractable hiccups during monthly therapy with high dose dexamethasone for multiple myeloma. Hiccups would begin hours after his first dose and continue over the 4 days of therapy. He sought assistance after his attempt at home remedies failed and the hiccups became exhausting. ⋯ Dexamethasone administration can result in intractable hiccups that persist for the duration of therapy. Low dose oral metoclopramide may prevent hiccups in patients in whom the discontinuation of dexamethasone therapy is not appropriate.

Clinical Trial
A phase II study of irinotecan (CPT-11) in patients with advanced squamous cell carcinoma of the cervix.
This study was conducted to determine the efficacy and safety of irinotecan (CPT-11) as second-line therapy in patients with advanced cervical carcinoma. ⋯ The amount of CPT-11 actually delivered to the patients under the conditions of this pilot study failed to result in an antitumor response. However, the marked subjective improvement of symptoms observed in this study and the significant activity reported by other investigators justify future studies of CPT-11 in patients with cervical carcinoma.

A pilot study of a new chemotherapy, the CIVIC regimen, was performed in 58 patients with metastatic breast carcinoma previously treated with chemotherapy with or without hormonal therapy (n = 41). Cisplatin, 20 mg/m2/day, was given (Days 1-5) every 21 days during a 1-hour intravenous (i.v.) infusion, and vinorelbine (VNB) was delivered at a dose of 6 mg i.v. bolus followed by VNB, 6 mg/m2/day, in continuous i.v. infusion (Days 1-5) every 21 days. ⋯ The CIVIC regimen is effective and has acceptable tolerance in patients with metastatic breast carcinoma refractory to previous anthracycline- and/or paclitaxel-containing chemotherapy. Four cycles were found to provide the best toxicity-efficacy ratio.
