Prognosis of cloacogenic and squamous cancers of the anal canal.

From 1968 to 1982, 195 patients with invasive cancer of the anal canal were treated (average age, 67 +/- 11 years; range, 38 to 85 years; sex ratio [women/men]: 5/1). Histology revealed: cloacogenic cancer, 20 cases; squamous cancer, poorly differentiated, 30; moderately differentiated, 68; well differentiated, 77. The initial size of the cloacogenic cancers was smaller than the squamous cancers. Invasion less than half the circumference of the canal was 90 and 74 percent, respectively. No patients with cloacogenic cancer presented with positive inguinal nodes; however, there were 22 unilateral and five bilateral positive nodes in the squamous cancers. All 195 patients received radiotherapy as the first treatment. There were no differences among the patients operated on with respect to sterilized operative specimens, postradiotherapy sequelae, perineal recurrences, and/or visceral metastases in the cloacogenic and squamous cancers. Five-year survival was better in cloacogenic (62 percent) than in squamous cancers (56 percent); this difference was not significant, and was related to the initial size of the tumor. The number of patients with no evidence of disease and good anal function was significantly related to the initial size of the tumor, and was independent of the histologic findings.

[Colonoscopy detection of polyps in patients operated on for colorectal cancer. Prospective study].

Subjects operated upon for colorectal carcinoma seem to constitute a population at high risk of a second colorectal malignancy and/or colonic adenoma (polyp). Ninety-four such patients were examined by colonoscopy. Their distribution by age and sex and the location of cancers in the colon were comparable to those reported in the literature. Colonoscopy was performed 12 +/- 6 months after surgery in 52 patients and was complete in 90% of them. Twenty-seven patients (52%) were found to have one or several polyps distributed throughout the colonic frame and varying in size from 2 to 75 mm (75% were less than 10 mm long). The larger the polyp, the more severe the dysplasia. Three malignant polyps were discovered; they were more than 10 mm in diameter. The colonoscopic examination was repeated annually over more than 3 years in 30 patients: at first repeat examination 54% had polyps which were still present in more than 30% at subsequent examinations. It is concluded that patients operated upon for colorectal carcinoma are at high risk of polyps and/or a second colorectal carcinoma and must therefore be followed-up by repeated colonoscopy.

[Cancer of the anal canal. Results of the treatment of a series of 195 cases].

Between 1968 and 1982, 195 patients with invasive anal canal carcinoma were treated at Institut Curie (Paris, France). There were 168 females and 27 males --sex-ratio: 5.7/1, mean age: 67 +/- 11 yrs. (range: 38-85 yrs.). The initial size of the tumors was analyzed according to the circumferential invasion of the anal canal. The tumor involved 1/4 of the circumference in 49 cases, 1/2 of the circumference in 108 cases, 3/4 of the circumference in 22 cases and the whole circumference in 16 cases. Pathological examination revealed 20 cloacogenic carcinomas and 175 squamous carcinomas. All patients received radiotherapy as initial treatment and none received chemotherapy as a curative procedure. Eight patients received only palliative treatment. Twenty-seven patients were operated on because the response of the tumor to irradiation was partial or incomplete. One hundred and sixty patients received the full course of irradiation with a complete response. Among the latter, 100 patients were alive NED with a normal anal function with at least a 2-year follow-up. Local recurrences (n = 42) underwent salvage surgery in 50 p. 100 of the cases with a 3-year survival over 50 p. 100. Actuarial survival of the 195 patients was 68.5 p. 100 at 3 years and 58 p. 100 at 5 years. Survival was highly related to the initial size of the tumor and to the presence of positive inguinal nodes (p less than 0.0002). The histologic type was not related to the response to radiotherapy, nor to local recurrence or to survival.(ABSTRACT TRUNCATED AT 250 WORDS)

Consistent deficiencies of chromosome 18 and of the short arm of chromosome 17 in eleven cases of human large bowel cancer: a possible recessive determinism.

Cytogenetic study of 11 cases of colorectal carcinoma was performed after R-banding. In all instances, there was a rearrangement involving chromosome 17 in its juxtacentromeric region, leading to the loss of its short arm. There was also a relative lack of chromosome 18, unrelated to a rearrangement of this chromosome in all but one case. Other anomalies, involving chromosomes 1 and 8 among others, were frequently but not systematically observed. The consistent lack of chromosome 18 and of the short arm of chromosome 17, leading to a complete or partial monosomy of these chromosomes in near diploid cells suggests that the passage to the hemizygous status of recessive genes carried by these chromosomes may play an important role in the development of colorectal carcinoma.

[Rearrangement of the chromosome 17 in colonic adenocarcinoma].

Chromosome studies on five cases of large bowel adenocarcinoma show a systematic rearrangement of chromosome No. 17 after breakage in its juxtacentromeric region (band 17 q 11). A frequent involvement of chromosome No. 8 (juxtacentromeric break) and the loss of chromosome No. 18 are also noticed. A review of the literature strengthens the hypothesis of a preferential involvement of these chromosomes in large bowel cancer.

Treatment of epidermoid anal canal cancer.

Between 1968 and 1979, 183 patients with invasive epidermoid cancer of the anal canal were treated at Institut Curie. There was 156 women, 27 men with a mean age of 67 +/- 11 years (range 40 to 85 years). The initial height of the tumor was less than 4 cm (65 patients), 4 to 6 cm (98 patients), and more than 6 cm (20 patients). All the patients received radiotherapy, either preoperatively or as curative procedure. Twenty-five patients received preoperative radiotherapy, and there was no residual tumor in 9 biopsies obtained at operation. Four local recurrences were observed. One hundred fifty-eight patients received curative radiotherapy, 115 of whom did not undergo operation. Eighty were alive with no evidence of disease and good anal function with a minimum of 3 years follow-up. We observed 15 local recurrences, 4 inguinal recurrences, and 8 visceral metastases. In addition, eight patients initially had such a big tumor that radiotherapy was only a palliative procedure. Forty-three patients required a surgical procedure after this curative radiotherapy. Colostomy (12 patients) or abdominoperineal amputation (25 patients) was required for local recurrence and colostomy was required for necrosis related to radiotherapy. Five year survival was 59 percent. The survival was related to the size of the tumor (p less than 0.0001). The likelihood of retaining normal anal function with local control of the tumor was also closely related to the initial size of the tumor.

[Cimetidine treatment of anastomotic ulcers (author's transl)].

Fifteen patients with anastomotic ulcer were treated with cimetidine for 30 days. Endoscopy showed healing or marked regression of the ulcer in 53% of the cases. Neither the type of operation previously performed nor the amount of gastric secretion prior to entering the trial gave any indication as to which patients would respond to treatment. Other authors using the same therapeutic regimen have obtained similar results, but some have reported that extending treatment up to 8 weeks seems to produce considerably better results. The present authors conclude that cimetidine may constitute a suitable alternative to a second surgical operation.

[Digestive hormones and gastric diseases. Facts and hypotheses (author's transl)].

Relationships between hormonal secretions from the GI tract and gastric functional and/or pathological abnormalities could be studied according to 2 main lines : 1) gastric secretory changes could be the main symptom of hormonal secretory tumors, i.e. acid hypersecretion in the Zollinger Ellison syndrome, acid hyposecretion in pancreatic cholera and in somatostatinoma. In these cases, hormonal hypersecretion is directly responsible for the functional disturbances and the related symptoms; 2) gastric pathological conditions are sometimes accompanied by changes in hormonal secretion, but the level of interdependence is variable : high blood gastrin is directly depending upon the atrophic gastritis in pernicious anemia; this mechanism was also suggested in case of gastric carcinoma. Concerning ulcer disease, numerous problems are unsolved in respect to blood gastrin (basal and stimulated) abnormalities, as well as somatostatin and GIP secretions.

Acute spontaneously recovering ulcerating colitis (ARUC). Report of 6 cases.

Six patients each with an extensive ulcerating colitis are reported. Common features were a febrile nonbloody diarrhea; radiological involvement of the whole colon with superficial ulcerations and preservation of haustra, and integrity of the terminal ileum and rectum; the absence of any specific pathological finding; and, most important, the spontaneous recovery of the lesions in the absence of any treatment except sympatomatic measures. The present follow up after recovery range from 18 months to 5 years. Four cases were young women taking oral contraceptives and two patients were older. These patients with colitis could represent a new entity or could be a particular form of Crohn's disease of the colon, with delayed diagnostic pathological features.
