Irradiation at the University of Michgan in the 1960's was carried out in 192patients with endolaryngeal carcinoma. Thirty-two and 66% of the cases were located inthe supreaglottic and glottic regions respectively. Cases were classified in stages appropiate TNM GROUPING. Results were analyzed with respect to tumor location, size, anddose-time relationship. Early lesions were controlled more often than advanced ones. Radical surgery to the primary and/or neck improved overall survival, which was 89% at 5years for 127 glottic carcinoma cases and 61% for 61 patients with supraglottic tumors. No significant complications were found following radiation therapy.

TNM classification is a short description of a cancer at a point in its natural history--the onset of definitive treatment--and should be considered in planning treatment, in assessing prognosis, in evaluating end results, in facilitating the exchange of information between treatment centres and thus in contributing to the continuing investigation of human cancer. For four cancers of urologic sites there are new TNM classifications. Although previous classifications of bladder cancer were satisfactory, the new classifications for kidney, prostate and testis are the first internationally accepted classifications for these three organs that are clinically practical. Widespread use of these classifications is recommended.

From 1963 to 1971, 105 patients with histologically proved cancer of the lung were explored at Memorial Hospital and underwent interstitial implantation using encapsulated sources of radon 222 (53 patients) or iodine 125 (52 patients). These lung cancers were considered unresectable because of extension of the disease into the mediastinum with fixation or invasion of the major vessels, trachea, and esophagus or chest wall involvement. No apical lesions, which have a better prognosis, are included in this review. Sixty-nine patients had epidermoid cancer, 24 had adenocarcinoma, and the remaining 12 had various other histological types. All patients were staged according to the criteria proposed by the American Joint Committee using the TNM definitions (standing for tumor, nodes, and metastasis). Local control was obtained in 8 of 10 patients (80% with clinical Stage I and II unresectable cancers of the lung and in 44 of the 95 (46%) with clinical Stage III lung cancer. The two-year survival was 50% for Stages I and II and 7% for Stage III. Five patients have survived for five years or more. The complications, disease-free interval, local recurrences, distant metastases, and survival are presented and indications for this type of therapy outlined.

Two hundred and thirty patients with glottic carcinomas of the larynx treated at the Radiumhemmet from 1956 to 1966 by radiotherapy and followed for at least five years were investigated. Histologic grading of malignancy was made in each case by the registration of eight morphologic criteria, four representing the tumor cell population itself (structure, differentiation, nuclear polymorphism, and mitoses) and four representing the tumor host relationship (mode of invasion, stage of invasion, vascular invasion, and cellular response). There parameters were graded on the bases of a one to four point system according to arbitrary units. Multivariate analysis of the material revealed that the most important factors in the prediction of the five year result were found to be the nuclear polymorphism, mode of invasion, and total malignancy point value. The histologic grading of malignancy in this series was found to be better in the prediction of the five year result, recurrence or not, than the TNM classification.

The development of generally valid rules for the treatment of cancer obviously requires the comparison of different forms of treatment and their results. The basis for these comparisons is a reliably reproducible and sufficiently detailed internationally applicable classification scheme for the characterization of tumors affecting different organs and their extent on the basis of objective findings. The TNM system proposed by UICC is the only one answering all these demands. It ought to become universally accepted and be the only system used.

This study reports initial experience at the Ellis Fischel State Cancer Hospital (EFSCH), Columbia, Missouri, with the analysis of variance and covariance as applied to the ability to predict the lethality associated with colorectal neoplasms as influenced by tumor,host, and treatment variables considered individually and as multivariate clusters. The application of the methods to the clinical setting is based on the fact that each patient has one survival time. However, in the mathematical sense, each patient is composed of many different variables interacting simultaneously in highly complex ways to determine this uniqueness. The feasibility of determining the prognostic score or weight of many variables is illustrated. The combinatory effect of these scores can provide prognostic scores for clusters of variables providing a tool of much greater specificity than is provided by traditional staging systems such as the TNM.

Studies of 169 cases of breast carcinoma showed that lymphatic metastasis was closely related to biological behavior of the cancer. Modified radical operation or modified extended radical operation were performed in cases of TNM stage I and II by pre- and intraoperative estimation of the tumor less than or about 5 cm in diameter, limited within mammary gland, and of expansion type. Histological typing and grading, degree of infiltration, condition of ER and lymphatic metastasis were used to plan postoperative adjuvant therapy. The importance of investigation of ER status of the lesions lies in proper arrangement of combined therapy and prediction of prognosis.

The cost of the first hospital stay for operable breast cancer was deducted by analysing a random sample of 100 admissions to the National Institute of Cancer during the period January-December 1989. The aims of the study were: (1) to describe and calculate the cost component of the stay; (2) to analyse whether any procedure, service rendered or stage of the pathology might explain differences in the total costs of the stay; and (3) to acquire a better knowledge of the organizational aspects to be improved. With an average length of stay of 14.1 days, the overall total cost observed was 4.9 million lira (US $3.800, 1989 US dollars). A significant correlation between total cost and duration of stay was found (R2 = 0.982), while no or very little correlation was found between cost and the anatomical extent of disease (TNM stage) and different cost items (laboratory, imaging tests, operating room, etc.). Two homogeneous groups of cases were found: patients with quadrantectomy and patients with mastectomy. The cost of the latter was 40% greater than that of the former (P < 0.001) with a length of stay 52% longer (p < 0.001). This study does not concern the costs immediately following the stay, which namely are higher for the quadrantectomy because the radiotherapy outpatient procedures. Attention should be paid to reducing the length of stay, keeping waiting time for organizational procedures to a minimum during the stay.

The incidence of periampullary cancer has been steadily rising in Korea. In the present study, we have reviewed 766 cases of surgically treated periampullary cancers, including 122 cases of our own, which were published in the Korean literature from 1984 to 1992. The 6th decade was the most prevalent age group, occupying 38% of the patients. The ratio of male of female was 1.7 to 1. Approximately 60% of lesion located at the head of the pancreas. Computed tomography which had 85% sensitivity was the most commonly employed modality for a diagnosis. The diagnostic sensitivity of percutaneous transhepatic cholangiography was 72%, of endoscopic retrograde cholangiopancreatography was 71%, and of ultrasonography was 54% in order of frequency. Tumor markers such as CA-19, CEA, and CA-125 were also studied in pancreatic cancer. The combinations of these markers recorded a higher positivity than using solely. The resection rate for lesions at the head of the pancreas was 21%, and that of distal common bile duct, ampulla of vater, and duodenum were 37%, 85%, and 50%, respectively. The morbidity and mortality rates after pancreatoduodenectomy were 44% and 12%, respectively. TNM staging revealed 66% of patients were in stage III, 26% in stage I, and 8% in stage II. The actual 5-year survival rates for cancer of the head of the pancreas was 11%, and that of duodenal cancer, distal choledochal cancer, and ampullary cancer were 21%, 18%, and 15%, respectively. In nonresected group, none survived over 18 months after treatment. Relatively high portion of lymph node metastatic patients may explain the poor survival observed in our series.

From 1978 through 1990, 90 total gastrectomy with esophagojejunostomy via thoracotomy were performed for the treatment of cancer of cardia or fundus of stomach. 85/90 patients were at TNM III-stage and 5/90-at IV-stage. 30-day post-resectional mortality was 1.1%. Five-year survival rate was 13.8%. 14CO2 respiratory test and clinical evaluation of 34 post-operative patients showed that total gastrectomy may decrease the incidence of positive residual cancer along the incision lines. It may also spare the patient from small-stomach syndrome. There was no statistical difference in postoperative fat absorption and digestive function between ordinary proximal subtotal gastrectomy and total gastrectomy.
