Mortality in workers at a northwestern United States prebake-type aluminum reduction plant was examined in a historical prospective (cohort) study. Although the standardized mortality ratio (SMR) for all causes of death was low (86), lung cancer (SMR 117), pancreatic cancer (SMR 180), lymphatic and hematopoietic cancers (SMR 184), fatal benign tumors of the brain (SMR 391), and pulmonary emphysema (SMR 204) showed excess deaths. Analysis of mortality by job-exposure category, duration of employment and latency suggests that some of the lymphatic and hematopoietic cancers (especially malignant lymphoma), lung cancers and pulmonary emphysema may be of occupational origin in this worker population.

In a sample of 1000 consecutive malignant neoplasms in Saudis resident in the Western Region of Saudi Arabia, malignant lymphoma was the commonest of the life-threatening malignancies. The differences between malignant lymphoma in this sample and Western series include the greater frequency of lymphoma; the tendency for reticulum cell and poorly differentiated lymphomas to present as abdominal lesions; the earlier peak of prevalence of Hodgkin's disease, and the dissimilar proportions of its subtypes. The distribution of cancers in the gastrointestinal tract in our sample is almost the reverse of that encountered in the West in that cancer of the mouth and esophagus were more common than cancer of the lower intestinal tract. Lung cancer was relatively uncommon. The smoking habit is not so prevalent in Saudi Arabia as in the West and there is a need to maintain this situation by discouraging smoking. Cancer of the breast was by far the commonest major malignancy in the female, although most Saudi women have their first child early in their reproductive life. Skin cancers proved to be the most prevalent malignancy, and of these squamous cell carcinoma was the most common. The biases that affect studies such as ours in Saudi Arabia are stressed.

This analysis indicated that patients with cancer-related pain account for 71.0% in author's material. After the TCM treatment, the effective rate were 91.6% in hepatocarcinoma-related pain; 86.1% in colon-rectal cancer-related pain; 68.2% in malignant lymphoma-related pain; 100% in irradiation-related pain of esophageal cancer, lung cancer, post-operative breast cancer. Results of "four-step analgesic ladder" showed that 52.1% of pain could be relieved by Step I (TCM therapy); if Step II (indomethacin) or III (phenylbutazone) was added, the rate of pain relief reached as high as 96.5%; and only 3.5% need to be treated by Step IV (Opioids). With less side-effects and addiction of opioids and other narcotics, the "four-step analgesic ladder" therapy seems to be more suitable for cancer pain relief in China.

Topoisomerase I represents a unique new target that can be exploited for development of new antineoplastic agents. There are now two new topoisomerase I inhibitors that are in early clinical trials that have generated a tremendous amount of interest. Topotecan (SKF 104864-A) is a topoisomerase I inhibitor that has been explored in phase I trials using a variety of dosages and schedules. The dose-limiting toxicity of the agent is neutropenia. Other toxicities include alopecia, very mild nausea and vomiting, anemia, and occasional fever. Responses have already been noted in patients with advanced, refractory ovarian cancer and non--small-cell lung cancer. The drug is currently undergoing intense phase II testing. Irinotecan (CPT-11) is also a topoisomerase I inhibitor, which has already undergone extensive phase I and early phase II clinical testing in both Japan and the United States. Dose-limiting toxicities of the agent have included neutropenia and diarrhea. Responses have been noted in patients with refractory colorectal cancer, non--small-cell lung cancer, lymphoma, ovarian cancer, head and neck cancer, pancreatic cancer, and breast cancer. There is no doubt both of these agents will be important additions to our chemotherapy armamentarium.

Pseudomonas cepacia is a gram negative rod, having no fermentative activity on glucose. This organism was detected in the sputum, throat swab, or throat washing of 22 inpatients treated between January, 1990, and December, 1990, at the First Department of Internal Medicine, Kagawa Medical School. The primary diseases for which these 22 patients were hospitalized were leukemia in 12, malignant lymphoma in 5, lung cancer in 2, myelodysplastic syndrome in 1, and embryonal cell carcinoma in 1. Twelve of the 22 patients had episodes of pneumonia which complied clinically with the diagnostic criteria provided to facilitate the National Nosocomial Infection Study. The complication of pneumonia occurred in 7 patients with leukemia, 2 with malignant lymphoma, 2 with lung cancer, and 1 with myelodysplastic syndrome. In 10 of these 12 patients, the organism was detected before the onset of pneumonia. All 22 patients in whom the organism was demonstrated had received antibiotics. The antibiotics which was most frequently used to treat these patients 1 month before detection of Pseudomonas cepacia were amikacin and ceftizoxime, which were used in 13 patients. Of the antibiotics in which the susceptibility to Pseudomonas cepacia was, evaluated, minocycline was effective in 100% (21/21), ceftazidime in 50% (11/22), and ofloxacin in 27.3% (6/22). Physicians should be especially aware of the possibility of colonization and nosocomial respiratory infection by Pseudomonas cepacia in patients with severe underlying diseases.

Nuclear Medicine offers screening methods for oncology such as bone and bone marrow scintigraphy. During the last two decades, special procedures have gained widespread application. This paper is centered around the "tumor-specific" radiopharmaceuticals. In patients with thyroid cancer, I-131 still plays a significant role. Ga-67 still has its indications in lymphoma, while in other diseases Tl-201 chloride is now the agent of choice. Especially in thyroid cancer, Tl-201 has proved to be a reliable tumor imaging radiopharmaceutical. More recently, Tc-99m MIBI was introduced for tumor imaging. Tc-99m HMPAO may also be used for tumor scintigraphy, especially in brain lesions. In addition, I-123 IMP has successfully been used for imaging malignant melanoma. Another promising field of tumor diagnosis is receptor imaging. In neuroblastoma and malignant pheochromocytoma, I-131/123 mIBG is the radiopharmaceutical of choice and may be considered as a receptor imaging agent also. First clinical results with In-111 octreotide show potentials as somatostatin-receptor radiopharmaceutical in insulinoma, islet cell carcinoma, medullary and lung cancer, while I-123 estradiol needs some improvement until it may be recommended as diagnostic tool in breast cancer. Since 1978, radiolabeled poly- or monoclonal tumor antibodies and their fragments have gained widespread application. Especially the Tc-99m 225.28S melanoma antibody, I-131 or Tc-99m CEA and In-111/I-131 labeled OC-125 antibodies have proven to be of clinical significance in melanoma, colorectal and ovarian cancer.

We reviewed clinical findings and serologic data on 18 men and three women with paraneoplastic cerebellar degeneration (PCD) associated with Hodgkin's disease (HD). The patients were 20 to 77 years old (median, 44). The lymphoma preceded neurologic symptoms by 1 to 54 months in 17/21 patients, but stage or activity did not correlate with severity of neurologic disease; six developed PCD while in HD remission. PCD evolved subacutely (over weeks to months) and was pancerebellar in most. Ten had downbeat nystagmus. Thirteen stabilized in a disabled state (wheelchair- or bed-bound), five stabilized ambulatory, and three, who had progressed to a nonambulatory state, recovered. The clinical findings were usually only cerebellar but one patient had an encephalopathy, three long-tract signs, and two sensory neuropathy. Plasmapheresis (seven patients) and corticosteroids or other immunosuppressant medication (eight patients) did not help; one improved dramatically after treatment with clonazepam. Two patients improved spontaneously. Six patients had serum antibodies that reacted specifically with Purkinje cells. The pattern was distinct from that of PCD with gynecologic cancer (anti-Yo) or small-cell lung cancer (anti-Hu). Western blotting failed to identify a discrete Purkinje cell antigen. Seropositive patients did not differ clinically from their seronegative counterparts. HD-associated PCD is more common in men and in a younger age group than in PCD with other malignancies.

Comparison of cancer morbidity and mortality rates between Mormons and Seventh-day-Adventists and the corresponding rates in the Federal Republic of Germany and the United States, reveals that mortality from malignant neoplasms in general is much lower in Mormons and Seventh-day Adventists than in the Federal Republic of Germany. The difference concerns in particular the tobacco-dependent tumors: compared to the rate of affected males in the Federal Republic of Germany, only some 25% of Mormon males are getting lung cancer. Similar patterns are found in laryngeal carcinoma. Tumors that are related to both alcohol and tobacco, such as carcinomas of tongue, pharynx and esophagus, are also significantly less frequent in Mormons. Malignant neoplasms of the female genital tract show distinct analogies: cervical carcinoma has a morbidity rate of only 26.7% of affected women in Germany. Accordingly, mortality rates of Mormons and Seventh-day Adventists show a significant lower level when compared with cancer data of lung, colon and rectum, and prostate from the best German cancer registry (Saarland). Some tumor rates are higher in Mormons, e.g. malignant melanoma, also all types of malignant lymphoma and myeloma. The life expectancy is generally elevated by 2-4 years in Mormons and Seventh-day Adventists. The association with the particular life style of both religious groups, especially the strict reduction of tobacco consumption, and factors of dietary and other habits is discussed.

The authors report a case of pulmonary squamous cell carcinoma which occurred after chemotherapy of non-Hodgkin's lymphoma (NHL). A 76-year-old man, who was admitted to our department because of swelling of cervical lymph nodes, was diagnosed as having NHL (follicular mixed cell lymphoma). He was treated with 11 courses of CHOP therapy. Thereafter, chemotherapy including ifosfamide was carried out for approximately three years. In June, 1991, he was readmitted to our department because of swelling and pain in his left thigh and an abnormal shadow on chest X-ray. Chest CT demonstrated a cavitated shadow (about 5 cm in diameter) with an irregular margin in right S1, which was suggested to be lung cancer or pulmonary infiltration of malignant lymphoma. Bronchoscopy, which was carried out on July 12, showed bloody sputa from the right B1 ramus and markedly reddened mucosa at the orifice of the right upper bronchus. Sputum cytology revealed no malignancy. ACVP-16 chemotherapy including ara-C, CBDCA and VP-16 was initiated on July 14 because of enlarged superficial lymph nodes. On July 18, he fell out of bed and fractured his left femur. He also suffered from respiratory failure. He died of pulmonary haemorrhage on July 26. Autopsy revealed pulmonary squamous cell carcinoma. The occurrence of pulmonary squamous cell carcinoma is rare after the chemotherapy of malignant lymphoma.

The availability of a new rapid and reproducible laboratory test led to an easy dosage of sialic acid (AS) serum levels in neoplastic patients. This substance, involved in tumoral transformation and metastatic spread, has been evaluated in 278 neoplastic patients: 183 patients were affected by lymphoma (96 NHL and 87 HD), 60 by breast cancer and 35 by lung cancer. All groups of patients considered showed mean values of AS higher than healthy controls and the positive percentages, compared with cut-off levels, were respectively: NHL 71%, HD 70%, breast cancer 38%, lung cancer 89%. Even if the low specificity of this marker limits its clinical validity, AS, that seems related to clinical course of disease, could be useful in the monitoring of many neoplasms.
