We examined ethnic differences in smoking and drinking habits among the five major ethnic groups in Hawaii (Caucasians, Japanese, Chinese, Filipinos, and Hawaiians) by means of questionnnaire data obtained from a representative sample of 8,636 Hawaii residents. For men, lifetime cigarette use was greatest among Caucasians and lowest among Chinese and Filipinos. For women, smoking cigarettes was highest among Caucasians and lowest among Chinese. Although overall smoking patterns showed some relationship to lung cancer incidence, the observed rates could not be fully explained. Beer consumption was greatest among Hawaiians of both sexes and least among the Chinese; most consumers of spirits (hard liquor) were Caucasian. Total alcohol consumption was similar among Hawaiians and Caucasians and was considerably greater than among the other 3 ethnic groups. Alcohol consumption patterns among men did not correlate well with esophageal cancer incidence, even when the analyses were restricted to smokers; among women, however, the correlation was high. For these sex- and ethnic-specific groups whose alcohol consumption was generally low, there was a negative association of amount consumed with mean annual family income. For the groups with higher proportions of drinkers, mean annual family income was higher among those who drank moderately (less than 5 ounces/wk) than among those who either drank more heavily or not at all.

The authors report the data on changes in peripheral circulation, depending on the kind of anesthesia, the amount of operative blood loss, alterations in circulating blood volume and localization of tumor in patients with cancer of the lung, esophagus and cardia. Totally, 35 patients (15--lung cancer, 10--esophageal cancer, 10--cancer of the cardia) were explored. In 25 cases fluothane was used as the main anesthetic, in 10--neuroleptanalgesia. The state of peripheral circulation was estimated by the period semielimination of radioactive xenon-133 from the muscle depot. It was found that alterations in peripheral circulation were not dependent on tumor localization, the use of fluothane and neuroleptanalgesia is associated with similar changes in peripheral blood flow and, finely, an increased loss of blood results in more pronounced alterations in peripheral circulation.

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.

The clinical use of photodynamic therapy (PDT) has been ongoing for over a decade. However, attempts to apply for approval of the therapy from boards of health for general use began only in 1989. The unique nature of PDT and the resultant changes in the normal drug registration process, as well as steps which are being taken to approve PDT for the treatment of endobronchial lung cancer, superficial bladder cancer and esophageal cancer are described. The current clinical status of PDT in these indications is also reviewed.

Cytochrome P450IIE1 is responsible for the activation of carcinogenic N-nitrosamines, benzene, urethane, and other low-molecular-weight compounds. Restriction fragment length polymorphisms (PstI and RsaI restriction enzymes) have been identified in the cytochrome P450IIE1 transcription regulatory region that may affect expression. This study describes the PstI and RsaI polymorphisms in different racial populations and in a case-control study of lung cancer. The allelic frequencies were markedly different in Japanese, African-Americans, and Caucasians: the PstI rare allele was present at a frequency of 2% in Caucasians, 5% in African-Americans, and 24% in Japanese (P < 0.05). For the RsaI rare allele, frequencies were 2% in Caucasians, 2% in African-Americans, and 27% in Japanese (P < 0.05). The assay was also applied to 128 individuals enrolled in a case-control study of lung cancer. Although limited in statistical power, the data indicate no evidence for an association in the aggregate of cytochrome P450IIE1 PstI [for which the odds ratio was 0.7 (95% confidence interval (C.I.) = 0.2-2.8)] or RsaI [for which the odds ratio was 0.9 (95% C.I. = 0.2-5.4)] restriction fragment length polymorphisms with lung cancer in this U.S. population. When analyzed by race, the lung cancer odds ratio for the PstI mutant allele in African-Americans was 0.19 (95% C.I. = 0.03-1.38), and in Caucasians it was 4.13 (95% C.I. = 0.34-48.8). For the RsaI mutant allele, the odds ratios were 0.20 (95% C.I. = 0.02-2.43) and 4.28 (95% C.I. = 0.35-50.6), respectively. The ethnic differences of these restriction fragment length polymorphisms might be related to genetic susceptibilities for lung cancer among Caucasians and for gastric or esophageal cancer among Japanese.

Between April 1980 and November 1990, we treated 212 cases of airway lesion using an Nd-YAG laser via the fiberoptic bronchoscope. The Nd-YAG laser power output was usually 40 W (20-60 W) delivered in 2 sec. shots. The cases consisted of 98 primary lung cancer, 12 primary tracheal cancer, 53 metastatic airway lesion, 7 benign tumor, and 42 cicatricial and granulomatous lesions. The therapeutic effects of Nd-YAG laser treatment were evaluated based on alleviation of dyspnea, widening of airway, and curative vaporization for therapeutic purposes. Effectiveness was observed in 180 of a total of 212 cases (84.9%). Out of 75 emergency cases in which a lifesaving procedure was performed to widen the airway, effective results were obtained in 70 (93.3%) with dramatic improvement in condition. It was also effective in 90 of 109 cases (82.6%) in which the procedure was performed for staged (palliative) widening of airway. In 55 cases of advanced lung cancer (Stage III or IV, mainly non-small cell cancer) in which palliative widening procedure was performed, one year survival was 44%. In 13 of 18 cases (72.2%) in which the procedure was performed for curative vaporization of invasive cancer, successful results were obtained. In 7 cases of benign tumor in which vaporization was performed as a radical curative procedure, no recurrence was observed in any cases. In 53 cases of metastatic airway lesion, effective results were obtained 48 (90.6%). The primary lesions of these cases consisted of 14 cases of esophageal cancer, 9 cases of lung cancer, 7 cases of colo-rectal cancer, 7 cases of thyroid cancer, and 16 others.(ABSTRACT TRUNCATED AT 250 WORDS)

The authors describe an autopsy case of a 68-year-old man with four primary cancers diagnosed at autopsy including malignant meningioma, early esophageal cancer, early gastric cancer and lung cancer. Recently, the number of patients with four and five primary cancers has been increasing. According to the Annual of the Pathological Autopsy Cases in Japan, 156 cases were reported during 16 years from 1974 to 1989. In this series, cancers were detected most frequently in stomach, colon, lung, prostate, liver and esophagus. However, only two cases with four and five primary cancers including malignant meningioma were reported. Because occult cancers like prostatic cancers are unexpectedly diagnosed at autopsy, the incidence of four and five primary cancers including malignant meningioma seems to be higher when the central nervous system is examined more frequently at autopsy.

This retrospective follow-up study evaluated the mortality experience of 4,323 men employed at a plant in Alabama (AL) that manufactures agricultural and other chemicals. On average, there were 18 years of follow-up per subject during the study period of 1951 to 1987. The observed numbers of deaths among cohort members were compared with the numbers expected on the basis of United States (US) and AL general population mortality rates. The all causes standardized mortality ratio (SMR), computed using US rates as the referent, was 97 (233 observed/240 expected deaths) for whites and 68 (47/69) for blacks. White subjects had more than expected deaths from buccal cavity and pharynx (BCP) cancer [SMR = 388; 95% confidence interval (CI) = 125-905] and from esophageal cancer (SMR = 417; 112-1,067). Their lung cancer mortality rate was 50% higher than the rate of US white men and 14% higher than the rate of AL white men. Each of these three cancers has strong nonoccupational determinants, the roles of which were not assessed and which may have been responsible in whole or in part for the observed increases. The excesses of lung and esophageal cancer were concentrated among short-term employees, an observation which also argues against a causal link with occupational factors. Black men experienced no increased mortality from BCP, esophageal or lung cancer, but results for blacks were imprecise. For white and black subjects combined, there were 3 observed versus 0.62 expected deaths due to soft tissue sarcoma (p = 0.05). The job histories of subjects with this type of cancer did not suggest any shared occupational exposure.

Preoperative staging in esophageal cancer is usually done by noninvasive tests. Currently, in the staging of lung cancer, when lymph nodes are identified preoperatively by CT or MRI to be greater than 1 cm, surgical staging using mediastinoscopy, Chamberlain procedures, or thoracoscopy are employed. We describe herein the use of thoracoscopy in routine preoperative staging of esophageal cancer. With the advent of newer laparoscopic techniques currently available, thoracoscopy plays an increasing role in the management of intrathoracic disease. Staging thoracoscopy as a routine preoperative invasive staging test appears to be a good diagnostic test.

While staging systems may seem complicated and cumbersome at times, they are designed to stratify patients into groups by prognosis and treatment. This article reviews the staging of lung cancer and esophageal cancer, and it shows how this classification translates into different treatment plans based upon this staging.
