In 90 patients with known extra-hepatic malignancy the liver was examined for metastases. The diagnostic value of clinical information, blood examinations, 99mTc scintiscan, and laparoscopy for the diagnosis of the liver metastases was evaluated. Clinical data (age, sex, time since onset of symptoms and localisation of primary tumor) are of no diagnostic value. The most reliable blood tests are alkaline phosphatase (AP) and GOT. The probability of liver metastastases rises with increasingly abnormal values of AP and GOT. However, the probability is not much greater in cases with highly abnormal values than in cases with only moderate elevation of AP and GOT. Diagnostic accuracy of AP is optimal by using a cutoff point of 76 U/l (sensitivity 79%, specificity 64%). Bilirubin, prothrombin time, haemoglobin and blood sedimentation rate are of very little value. Combinations of AP with these blood tests does not improve diagnostic accuracy. Therefore, it is not useful to determine more blood tests than AP alone. Informed reading of liver scans has a specificity of 75% and a sensitivity of 91%. Blind reading of scans has a sensitivity of 94% and a specificity of 95%. This diagnostic accuracy cannot be improved by additional blood tests. Laparscopy has a sensitivity of 85% and a specificity of 95%. Scanning and laparoscopy are complementary methods. When optimal diagnostic accuracy is required both methods should be used.

Visual disturbances in patients with breast carcinoma may result from choroidal metastases. Metastases were bilateral in 41% of patients and the choroid was the first site of metastasis in 25%. Therefore awareness of this 'rare' condition is essential for any doctor seeing patients with breast cancer; consultation with an ophthalmologist and radiotherapist is mandatory. Radiation therapy is the treatment of choice, producing an 80% response rate (complete resolution in 25%). The final catastrophe of blindness in these patients can be prevented.

Between 1969 and 1985, 45 patients with carcinomas of the nasal cavity proper received curative treatment. Thirty patients had squamous cell carcinoma, one had undifferentiated carcinoma, 9 had adenocarcinoma, and 5 had adenoid cystic carcinoma. Eighteen patients were treated with definitive radiotherapy (interstitial brachytherapy in 5 and external beam therapy in 13 patients), and 27 received surgery and radiotherapy. The median length of follow-up was 11 years (range: 2.8-16.8 years). Thirty-six patients had no evidence of disease at the last follow-up visit. All 14 patients with carcinoma of the nasal septum had the disease controlled. Nine of 31 patients with lesions of the lateral wall and floor died of the disease, 5 of uncontrolled local disease, 2 of distant metastases, and 2 of both. The disease-specific survival rates at 5 and 10 years were 83 and 80%, respectively, and the corresponding overall survival rates were 75 and 60%, respectively. Blindness occurred in 4 patients, 2 due to orbital exenteration and 2 to radiation injury to the cornea and optic pathway. Other infrequent side effects were bone necrosis, dental decay, nasal stenosis, and septal perforation. This study indicated that the prognosis of patients with nasal cavity carcinoma was better than that of patients with maxillary sinus cancer treated during the same era. In addition, the study showed that carcinomas of the nasal septum were smaller than those of lateral wall and floor at diagnosis, so that excellent control could be achieved by definitive radiotherapy; when accessible, interstitial brachytherapy might be the treatment of choice in such patients.

To detect numerical chromosomal abnormalities (NCA) in malignant cells on body fluids, Fluorescence in situ hybridization (FISH) technique was tested in clinical specimens from patients with metastatic disease. Directly labeled DNA probes specific for chromosomes 8, 12, X, and Y (Imagenetics, Naperville, IL) were used for in situ hybridization to interphase cell nuclei. Fifteen body fluids (BF) from various sites were studied. Based initially on the Papanicolaou-stained slides, there were seven malignant and eight benign samples. Blind analysis (200 cells/sample) showed that all benign samples had a normal number of chromosomes, whereas six of seven malignant samples showed different NCA comprising 5-60% of the cell population ranging from three to 10 chromosome signals per cell. We conclude that interphase cytogenetic cell analysis of BF by FISH is: (1) feasible and gives superior signals for detection of NCA, (2) helpful in detecting malignant cells, (3) relatively simple with a turnaround time of less than 24 hr. This method may have diagnostic and prognostic application in the study of the biologic behavior of malignant neoplasms.

A 59-year-old man underwent total gastrectomy for diffuse, poorly differentiated gastric adenocarcinoma diagnosed as linitis plastica. Loss of vision in the right eye 5 months later due to extensive choroidal tumours was the first indication of metastatic disease. Radiologic studies showed multiple bony metastases. The blind, painful eye was enucleated. Pathological examination of the globe showed massive metastatic mucus-secreting adenocarcinoma of the choroid, with positive immunohistochemical staining for carcinoembryonic antigen (CEA) of the foci of the more highly differentiated neoplastic cells. The plasma CEA level had been normal. The patient died 3 months after enucleation from metastatic disease.

In 62 patients with thyroid carcinoma 79 MRI bone marrow examinations and 48 bone marrow scintigraphies were recorded before or following radioiodine therapy, to study the extent of bone marrow expansion. The results of both methods were the same. In 34/79 investigations normal findings were seen, in 18 the bone marrow expanded to the middle third and in 26 to the distal third of the femur. One patient showed bone marrow expansion to the tibia. These results were compared with the following data: histology of tumor, TNM-staging, time passed since thyroidectomy, accumulated doses of radioiodine therapy, results of 131I scintigraphy, hematological changes, thyroglobulin level, age and sex. No significant correlations were found between these and the bone marrow imaging results. Bone marrow changes in patients before radioiodine therapy were similar to those in patients treated with up to 48 GBq 131I. Blind biopsy of the posterior iliac crest in five patients showed slightly pathological reactive changes. In only 2/17 follow-up studies an increase of bone marrow expansion was seen. In 8 patients localized findings indicating malignant infiltration were observed. In 4/8 patients metastases of thyroid carcinoma were known or confirmed by pathological radioiodine uptake and in 2/8 metastatic involvement was assumed because of an increased thyroglobulin level.

A retrospective analysis was conducted of 152 patients with carcinoma of the nasal cavity and paranasal sinuses who were treated with radical radiotherapy between 1975-1984. Stages at presentation were T1 11%, T2 18%, T3 27%, and T4 44%. The median follow-up was 61 months. The overall corrected 5-year survival was 47% and by T stage, T1 86%, T2 82%, T3 49%, T4 25%. Local control was achieved in 45% of cases following radiotherapy. Salvage surgery was attempted in 20 patients where radiotherapy failed and was successful in eight. Nodal disease was present in 6.5% of patients at presentation and 10.5% developed nodal disease after treatment. Nodal disease as sole relapse occurred in four patients and was associated with prolonged survival following radical salvage treatment. Distant metastatic disease occurred in 25 patients and of these 17 (68%) also had locoregional failure. Osteoradionecrosis occurred in three cases, and a further three cases developed bilateral blindness. We conclude that radical radiotherapy achieves results comparable to published data for combined surgery and radiotherapy with acceptable toxicity.

A 13-year-old boy presented with blindness and loss of the papillomacular bundle in the left eye, bilateral papilledema sparing the area of axonal loss, and Parinaud's syndrome. Computerized tomography (CT) revealed an enlarged kinked left optic nerve and enlarged optic canal as well as a tumor in the pineal area producing hydrocephalus. Magnetic resonance (MR) scans showed multiple spinal metastases. The histological diagnosis was germinoma. On completion of four courses of chemotherapy with cis-platin, vinblastine, and bleomycin, repeated CT of orbita and MR imaging of the spine demonstrated the disappearance of the tumor surrounding the left optic nerve and of the spinal metastases. This is believed to be the first case report of seeding of germinoma into the perioptic arachnoid space.

A 72-year-old woman developed recurrent blindness on exposure to bright light (sunlight). Examination revealed total achromatopsia; bilateral central scotomas, predominant suppression of the cone response by electroretinography, and narrowing of the retinal arteries on ophthalmoscopy. The general examination revealed a pelvic tumor that later proved to be a pleomorphic carcinoma of presumed uterine origin. The patient died of metastatic disease 9 months after the ocular symptoms developed. Histopathologic examination of the eyes revealed loss of the photoreceptors, most extensive in the macular regions, and selective loss of the cones from the rest of the retinas. No ocular metastases of inflammation were found. The changes described are interpreted as paraneoplastic retinopathy of autoimmune origin.

A retrospective study was performed on 30 cases with choroidal metastases referred to the Cancer Institute Hospital between July 1975 and June 1986. Of these 30 cases, 32 eyes of 26 patients were treated with irradiation of 4.3 MV X-rays or 12 MeV electron beam therapy in the range of 20-60 Gy to restore vision and prevent blindness. The tumor response to radiation therapy confirmed by ophthalmoscopic examination was described as complete, partial or no response. Of the 32 eyes, 31% had complete response, and 47% showed partial response. The overall response rate was 78%. A visual response as defined by marked or partial improvement of visual acuity and/or subjective symptoms was obtained in 16 out of 26 patients (62%). All of these patients were free of recurrence of symptoms in their quality of life. This proved radiotherapy to be a useful modality of treatment for choroidal metastases. No obvious radiation injuries were encountered in this series.
