Randomized Controlled Trial Comparative Study Clinical TrialA randomized cross-over trial of granisetron and dexamethasone versus granisetron alone: the role of dexamethasone on day 1 in the control of cisplatin-induced delayed emesis.
We studied the role of dexamethasone (DEX) administered on day 1 in controlling cisplatin-induced delayed emesis. Forty patients were randomly allocated to receive either granisetron (GRN) and DEX on day 1, or the same dose of GRN alone. On days 2-5, all the patients received metoclopramide and DEX. ⋯ The mean numbers of emetic episodes on days 1-3 were 0.036, 0.46 and 0.36 for GRN and DEX, and 0.39, 0.89 and 0.57 for GRN alone, respectively (P<0.01 on day 1). Hiccups and restlessness were noted in 38% and 33% of cycles, respectively. Addition of DEX to GRN on day 1 thus enhanced the control of delayed emesis.

Clinical usefulness of serum carboxyterminal propeptide of type I procollagen and pyridinoline cross-linked carboxyterminal telopeptide of type I collagen in patients with prostate cancer.
A study was undertaken to evaluate the clinical usefulness of measurements of serum concentrations of the carboxyterminal propeptide of type I procollagen (PICP) and the pyridinoline cross-linked carboxyterminal telopeptide of type I collagen (ICTP) as parameters of bone metastasis in patients with prostate cancer. Serum PICP, ICTP, prostate-specific antigen (PSA), and alkaline phosphatase (ALP) were evaluated in 82 patients with prostate cancer and 26 patients with benign prostatic hyperplasia (BPH). These markers were measured serially in 16 prostate cancer patients during treatment. ⋯ PICP and ICTP levels varied with ALP and PSA levels, the patient's clinical course after the start of endocrine therapy and the progression of bone metastasis. The levels of PICP and ICTP did not change substantially in patients who developed local regrowth or lymph node metastasis, and decreased as bone metastases responded to radiotherapy. PICP and ICTP thus reflect the metastatic burden in bone and are useful for monitoring the response of bone metastasis to therapy.

Randomized Controlled Trial Multicenter Study Clinical TrialFive-year results of a randomized controlled trial of adjuvant chemotherapy for curatively resected colorectal carcinoma. The Colorectal Cancer Chemotherapy Study Group of Japan.
In order to evaluate the significance of postoperative adjuvant chemotherapy for colorectal carcinoma, the Colorectal Cancer Chemotherapy Study Group, from 140 leading hospitals in Japan, conducted a prospective, randomized, controlled trial on patients who had undergone curative resections for colorectal carcinomas during the period from February 1984, to December 1985. The regimens for colon cancer were, Arm I: mitomycin C [intraoperative portal vein bolus (12 mg/m2) + postoperative, twice weekly and then three times bimonthly for six months intermittent i.v. bolus (6 mg/m2)] + 5-fluorouracil (5-FU) 200 mg/body/day p.o. for six months; Arm II: postoperative twice weekly and then three times bimonthly intermittent i.v. bolus mitomycin C (6 mg/m2) for six months + 5-FU 200 mg/body/day p.o. for six months; Arm III: surgery alone. The regimens for rectal cancer were, Arm IV: same as Arm I, with superior rectal artery infusion of the same mitomycin C dose instead of portal vein infusion; Arm V: same as Arm II; Arm VI: same as Arm III. ⋯ We conclude the adjuvant use of long term oral 5-FU and intermittent mitomycin C (i.v.) to improve the survival rate of patients with curatively resected rectal cancer. Further comparative study is, however, recommended to confirm the effectiveness of 5-FU alone and the combination of 5-FU and mitomycin C. Regional chemotherapy made no contribution to reducing an hepatic recurrence of colon cancer or a local recurrence of rectal cancer.

Multicenter Study Clinical TrialConcurrent cisplatin-etoposide chemotherapy plus thoracic radiotherapy for limited-stage small cell lung cancer. Japanese Lung Cancer Chemotherapy Group in Japanese Clinical Oncology Group.
A recent approach in the treatment of limited-stage small cell lung cancer (LDSCLC) has involved a combined modality of chemotherapy and chest irradiation. In using the modality, the study of scheduling methods for combining chemotherapy and radiotherapy should lead to other trials of combined modalities against LDSCLC since it is the most basic issue to be evaluated. We have thus conducted a multicenter phase II trial of concurrent cisplatin-etoposide (PVP) chemotherapy and radiotherapy for LDSCLC to determine the effects of the concurrent administration of a PVP regimen and chest irradiation on response rate, relapse, survival and treatment toxicity. ⋯ Other toxicities, including radiation-induced esophagitis and pneumonitis, were deemed almost acceptable. We concluded concurrent treatment of a PVP regimen with chest irradiation to be a feasible and beneficial therapy with an efficacy compatible to that of other published reports. The outcome of this protocol warrants further investigation to determine the optimal type of schedule for concurrent chemoradiotherapy against LDSCLC.

Case ReportsLaryngeal metastasis from a pulmonary papillary adenocarcinoma: a case report.
Metastases to the larynx from distant primaries are very rare. The present article reports a case of metastatic papillary adenocarcinoma of the larynx of lung origin. The patient was a 59-year-old female non-smoker, who had a history of adenocarcinoma of the right lung. ⋯ The tumor of the larynx was a papillary adenocarcinoma resembling the lung tumor, both demonstrating positive immunohistochemical staining for pulmonary surfactant apoprotein. The findings emphatically indicated the laryngeal tumor to be metastasis from the primary papillary adenocarcinoma of the lung. The present case report presents the clinical findings, course of disease and histopathological findings with brief reviews of the literature.
