[Effects of infusion of cis-platinum into the bronchial artery in lung cancer].

5 patients with histologically and/or cytologically confirmed lung cancer were treated with Cis-platinum (CDDP) infused into the bronchial artery (BAI). 2 patients with squamous cell carcinoma disclosed hypervascular type and 3 patients with adenocarcinoma demonstrated avascular or hypovascular type on bronchial arterial angiography. All patients showed more than 20% shrinkage of the tumor shadow on chest X-ray taken 2 weeks after BAI and were evaluated to be radiologically effective by Takeuchi's criteria. One patient with squamous cell carcinoma who underwent lobectomy after BAI with 100 mg of CDDP showed grade III histological effects by Shimosato's criteria. The other patient had superior vena cava syndrome and showed regression of a tumor which occluded the orifice of the right upper and showed lobe after BAI with 100 mg of CDDP. By of contrast, only 1 out of the 3 patients with adenocarcinoma who under went resection showed a grade IIa histological effect after BAI with 50 mg of CDDP. Side effects included mild gastrointestinal toxicity in 1 out of the 5 patients. In conclusion, BAI with CDDP was shown to be sufficiently useful as a chemotherapeutic modality for lung cancer, especially for patients with squamous cell carcinoma, because higher local doses can be delivered without systemic toxicity.

Effect of human leukocyte interferon on malignant brain tumors.

The antitumor effect of human leukocyte interferon was investigated on ten patients with malignant brain tumor. In eight cases of primary tumor, IFN alone was administered when their recurrent sign was evident. A dose of 3 X 10(6) IU or 1 X 10(6) IU of IFN was injected intramuscularly two or three times a week in high-dose group, while a dose of 5 X 10(4) IU once a week in low-dose group. No remarkable side effects including bone marrow depression were noted. Natural killer activity was enhanced and immunologic skin reaction manifested. Partial remission of more than 50% decrease of tumor volume calculated on CT scan was seen in two cases in the low-dose group for about 3-6 months. Complete remission could not be obtained by IFN alone. Our pilot study has shown that IFN alone will not be effective against progressive malignant brain tumors by general administration. Further investigation should be carried out to improve the use of IFN therapy in malignant brain tumor.

Local administration of interferon for malignant brain tumors.

We investigated the effects of local administration of interferon (IFN) on 13 patients with recurrent brain tumors. Histologic diagnoses were glioblastoma (eight patients), medulloblastoma (one), ependymoma (one), ependymoblastoma (one), pontine glioma (one), and astrocytoma (one). When tumor recurrence was evident local administration of IFN was started through an Ommaya reservoir, which was placed during repeat craniotomy. No tumor regressions were seen in the patients given weekly injections of IFN; however, in two of six patients given daily injections, a decrease of tumor volume and augmentation of natural killer activity were seen.

[Clinical experience in patients with Pancoast's tumor treated by fast neutron therapy].

We review our results with fast neutron therapy in Pancoast's tumor, and compare them with results obtained by photon beam therapy. 13 patients with Pancoast's tumor were divided into two groups; Group I (8 patients) received fast neutron therapy. Group II (5 patients) were treated by voltage X-ray therapy. 1. Group I was comprised of 3 patients receiving mixed beam therapy (TDF 80-100) and 5 patients subjected to boost therapy. All group II patients received 3100 to 8000 rads. 2. Fast neutron therapy was effective in 7 patients. In group II, high voltage X-ray therapy was effective in only 3 patients. 3. Two group I patients are still alive without signs of recurrence. The others died with a mean survival of 11 months. All group II patients died; their mean survival was 4.2 months. Our results suggest that fast neutron therapy is suitable and effective in patients with Pancoast's tumor.

Granular cell myoblastoma of the bronchus in a child: a case report.

Granular cell myoblastoma of of the right main bronchus in a 5-year-old girl is reported. The tumor extended to the lower trachea from the right main bronchus which was occluded completely by the tumor. The diagnosis was established histologically by a obtaining bronchoscopic biopsy specimen. Right pneumonectomy was carried out to control pulmonary suppuration caused by the tumor obstruction of the bronchus. External radiotherapy and interstitial brachytherapy were successful to control the growth of the residual tumor. She has been free from symptoms for about 12 years after the treatment.
