Is curative endoscopic treatment of early gastric cancer possible?

Fifty-four lesions found in 51 cases of early gastric cancer were treated with the Nd:YAG laser, N2 dye laser, local injection of ethanol, polypectomy and a combination of these methods between November, 1980 and July, 1986. Among these lesions, 34 were followed for more than one year with the endoscope. In 86% of the lesions treated, no recurrence of cancer was detected during the observation period, nor were there any deaths from gastric cancer. An analysis of the results showed that local cure of early gastric cancer in the mucosal layer could be accomplished with many kinds of endoscopic devices and that the difficulties for curative treatment depended on tumor localization and size. Further, we were able to assess local cure after endoscopic treatment on the basis of the endoscopic features of the tumor; local cure presents as a scarred stage with a smooth surface and with no abnormal granules or irregular redness. At present, endoscopic treatment should however, be limited to inoperable cases, since we cannot definitively diagnose lymph node metastasis or depth of cancer invasion.

Restriction fragment length polymorphism detected by human salivary amylase cDNA.

The plasmid clone which contains human salivary amylase cDNA was used to detect restriction fragment length polymorphisms (RFLPs). After double digestion with Pst 1 and Bam H1, a polymorphism with two alleles was observed. In Japanese, frequencies of these alleles, tentatively called 5.7 kb and 6.5 kb fragment alleles, are 0.55 and 0.45, respectively.

[Role of hysteroscopy in diagnosis and management of trophoblastic disease].

To confirm complete removal of trophoblastic tissues, hysteroscopy was performed in 21 patients after evacuation of hydatidiform mole with an interval of a week. In 15 of these cases, hysteroscopy employed within a week after evacuation of the mole revealed a residue of mole or necrotic decidua. Although complete removal was confirmed in 14 cases on the second hysteroscopy, re-curettage was necessary in 6 patients because necrotic tissues were still found in the uterine cavity. Possible diagnosis of invasive mole was made in 2 cases within 2 weeks after evacuation of the mole by hysteroscopic findings. Hysteroscopy was also performed in 27 patients who were suspected of having a trophoblastic disease from the clinical signs and urinary hCG titer. Hysteroscopic findings which suggested trophoblastic diseases were summarized in the following four categories; 1) the existence of vesicles, 2) buldging or 3) recess of the uterine wall with bleeding or dilated blood vessels and 4) hematoma of the uterine wall. In 9 of the 21 cases with choriocarcinoma, invasive mole or persistent trophoblastic disease, one or two of the above mentioned findings were noted. Moreover, it was possible to differentiate syncytial endometritis from trophoblastic disease from the hysteroscopic findings. Therefore, hysteroscopy seems to be a useful aid not only in confirming complete evacuation of hydatidiform mole but also in the diagnosis and management of malignant sequela.

[Calcifying mucinous adenocarcinoma of the stomach--case report].

In a patient with mucinous adenocarcinoma of the stomach and metastatic lesions in the lung and lymph nodes , X-ray films demonstrated multiple punctuate calcifications. We collected reported cases of gastric cancers with radiographically visualized calcium deposits and discussed their characteristics.
