Natural history of "early" gastric cancer: results of a 10-year regional survey.

In "early" gastric cancer the depth of invasion by the primary tumour is confined to the submucosa of the stomach. Out of 13228 cases of gastric cancer notified to the Birmingham Cancer Registry during 1960-9, 90 (0 . 7%) were identifed as early gastric cancer. The crude five-year survival rate of these 90 patients was 57 . 8% (age-adjusted rate 70 . 4%) compared with 3 . 7% (age-adjusted rate 4 . 7%) for all cases and 14 . 6% (age-adjusted rate 17 . 4%) for the cases treated radically. Prognostic factors established for gastric cancer pertained equally to early gastric cancer. Most of the 90 patients had had symptoms related to the gastrointestinal tract, but in contrast to patients with advanced gastric cancer only 19% had lost weight on admission. These findings suggest that early investigation of dyspeptic symptoms would increase the detection of early gastric cancer, the most important prognostic group identified in gastric cancer.

A theoretical and experimental study of light absorption and scattering by in vivo skin.

A theoretical treatment has been developed for the optical properties of a layered structure which absorbs and scatters light. This theory predicts that the logarithm of the inverse of reflectance (LIR) of the surface should be a useful parameter for the examination of that structure. This approach has been applied to a study of skin in vivo. An instrument was constructed for use in clinical situations to measure the LIR spectrum of skin over the visible region of the spectrum (450-760 nm). The contributions to the observed spectra made by pigments and the skin structure were deduced by reference to the theoretical model. Numerical indices were used to quantify the changes in skin haemoglobin content following the application of vasoconstricting preparations. The indices also provided a means of measuring erythema and melanin pigmentation induced in the skin by exposure to ultraviolet radiation. The assessments made using this instrument were more reproducible and sensitive than judgments made by eye.

Gastric carcinoma and previous peptic ulceration.

The incidence of patients with gastric carcinoma having had a previously diagnosed or suspected peptic ulcer was noted in two studies. These studies were the West Midlands Gastric Chemotherapy Trial (1974--6) and a retrospective study of patients presenting to the United Birmingham Hospitals with gastric carcinoma during the years 1958--62 and 1968--72. The incidence of patients found to have had a previous operation for duodenal ulcer or to have post-mortem evidence of one was 6.5 per cent and 5.7 per cent respectively. A radiologically proved duodenal ulcer had been identified in 5.5 per cent and 2.1 per cent respectively and the incidence of previous symptoms suggestive of a duodenal ulcer was 4.0 per cent and 5.2 per cent. These figures indicate the total incidence could be 12.97--16.0 per cent, which is much higher than previously reported. The mean time interval between operation for duodenal ulcer and the development of gastric carcinoma was much longer in patients having had a partial gastrectomy than in patients having had a vagotomy and drainage procedure. The incidence of previous benign gastric ulcers was 2.5 per cent and 0.9 per cent. Fifty-three per cent of patients having had a previous operation for duodenal ulceration were found to have an unresectable carcinoma, compared with the overall unresectable rate of 35 per cent.

Carcinoembryonic antigen levels in advanced gastric carcinoma.

Serial CEA levels were measured in 157 patients with advanced inoperable gastric carcinoma entered in a controlled trial of cytotoxic therapy. In 49 (31%) of cases initial levels were greater than 50 ng/ml. However, serial measurements were only possible in 57 (36%) cases and results were prognostically valuable in only 15 (9.5%) of cases.

Garré's osteomyelitis of the mandible. Report of a case.

A case of Garré's disease has been reported. This case is atypical in that the patient presented with only a periosteal bone mass and a negative history of toothache, abscess, or trauma to the area. Because of this, diagnosis was not possible without microscopic examination. Atypical cases of this nature cause diagnostic problems, and several disease states must be considered in a differential diagnosis. These include the following: 1. Ewing's sarcoma, which also occurs in this age group and may show cortical reduplication on radiographic examination. The prognosis in cases of Ewing's sarcoma is poor, and death may occur in a matter of weeks. 2. Infantile cortical hyperostosis (Caffey's disease), which is characterized by development of soft-tissue swelling and cortical thickening of the mandible. The disease runs a benign course and regresses without treatment. 3. Osteogenic sarcoma, which occurs in slightly older age groups but presents as a cortical expansion with facial deformity. The disease is highly malignant and carries a poor prognosis.

Reticulum-cell sarcoma of the mandible.

A case of reticulum-cell sarcoma of the mandible is presented. This case is of interest because a secondary primary malignancy was diagnosed in a patient with Hodgkin's disease and a localized osteomyelitis. If reticulum-cell sarcoma of bone, which is highly radiosensitive, is diagnosed at an early stage, the 5-year survival rate has been reported at 73 per cent when treated by irradiation; radical surgery is not indicated.
