Adenoma--carcinoma sequence or "de novo" carcinogenesis? A study of adenomatous remnants in a population-based series of large bowel cancers.

Although it is well known that colorectal cancers can arise on a preexisting adenoma or de novo, the relative importance of these two pathways is still highly controversial. The authors studied the proportion of cancers with adenomatous remnants in a nonselected population-based series of 1630 resected colorectal cancers, so that they could estimate by subsite the importance of the adenoma-carcinoma sequence. Four factors appeared to be related independently to the presence of adenomatous tissue within cancers in a multiple logistic model: tumor extension, growth pattern, location, and size. It appeared that infiltrating and ulcero-infiltrating tumors, which represented 39.8% of all resected colorectal cancers, very rarely displayed adenomatous tissue (0.5%), whereas it was more common in fungating and ulcero-fungating cancers (25.8%; P less than 0.001). In these exophytic cancers, the presence of adenomatous tissue was related very closely to the tumor size and extension, and it was seen in as many as 83% of small cancers (less than 2 cm) limited to the mucosa or submucosa. Right colon cancer showed consistently fewer adenomatous remnants than left colon or rectal cancer. These figures suggest that there are roughly two types of colorectal cancers, one of the infiltrating or ulcero-infiltrating type, which usually would arise de novo and account for approximately 40% of all colorectal cancer cases, and the exophytic type, which would mainly follow an adenoma-carcinoma sequence, although some might be de novo cancers, in particular in the right colon.

Prognosis of gastric carcinoma after curative surgery. A population-based study using multivariate crude and relative survival analysis.

A population-based series of 246 gastric cancer patients operated for cure and who survived the postoperative phase was reviewed to determine prognostic factors after potentially curative treatment. The overall five-year observed survival rate was 34.8%, and the relative survival rate was 43.9%. Previous history of gastric ulceration, tumor location, tumor size, gross appearance, extension within the gastric wall, and number of proximal lymph nodes involved were significantly related to both crude and relative survival rates. Age was a significant prognostic factor when considering crude survival rates, but it had no influence on relative survival rates. Multivariate analysis of crude and relative survival gave similar results except for age. The covariates retained in the final model were, by decreasing importance, extension within the gastric wall, lymph node involvement, gross appearance and tumor location. Combining the two major prognostic criteria, tumor extension through the gastric wall and lymph node involvement, four prognostic categories could be determined with five-year corrected survival rates ranging from 92% in patients with a carcinoma limited to the gastric wall to 17% in patients with more than two positive nodes whatever the extension in the gastric wall. Gross appearance had no influence on prognosis for carcinomas limited to the gastric wall, but had a significant impact on prognosis of more extended carcinomas. From these data, a simple staging system requiring only routinely available pathological data was proposed. This classification could be helpful for planning multicenter clinical trials on this disease where progress in therapy is needed.

Views of a general population on mass screening for colorectal cancer: the Burgundy Study.

BACKGROUND: The success of a screening program depends on a number of factors, including the validity of the test, its efficacy, its feasibility, and the rate of compliance. Thus, it is important to determine the factors influencing compliance to the screening test in order to obtain a high participation rate. METHODS: A mass screening campaign for colorectal cancer using the Hemoccult test was conducted in Burgundy, France. One year later, a questionnaire was mailed to a random sample of the population to assess the views of the general public (870 persons who had not completed the Hemoccult test, 750 persons who had a negative test, and 100 persons who had a positive test). The compliance rate of this survey was 32.2% among persons who had not completed the screening test, 88.2% among persons with a negative result, and 98.0% among persons with a positive result. RESULTS: The main reason for not participating was not wanting to know more about their health status (34.3%). Of the factors credited with encouraging persons to perform the test, the most important ones were the practitioner's explanations (55.7%) and the leaflet sent by mail (42.5%). The impact of the media campaign was weak. A small portion of the population (4.3%) said that they were very anxious while waiting for the results. Among persons with a positive screening test, only 1.2% regretted having taken it. Among those who took the test, 94.2% said they were ready to do it again; and among those who did not take it, 36.7% would accept it at a second screening. CONCLUSIONS: The data suggest that overall the Hemoccult is well accepted, that the campaign did not upset the population, and that it is worthwhile at the second screening to include those who did not participate in the first screening test.

Different multiple regression models for estimating survival: use in a population-based series of colorectal cancers.

Two additive models for estimating relative survival, recently available in statistical packages, were compared to the Cox model in order to define practical criteria for choosing one of these three models. The three models were applied to a series of 1062 colorectal cancer incident cases recorded at the "Registre des Tumeurs Digestives de Côte d'Or" to study the impact on survival of age, sex and socio-economic status. The respective advantages of each method and facilities of each program were identified. This study emphasized the importance of multiple regression models for estimating relative survival: from the epidemiologist's point of view, they reinforce the validity of international comparisons of survival statistics, from the clinician's point of view, they permit to identify the real prognostic significance of variables related to life expectancy in the general population.

Epidemiology, management, and prognosis of malignant large bowel polyps within a defined population.

The population based registry of digestive tract tumours established for the department of Côte d'Or, France (population 480,000) was used to study the epidemiology and management of malignant large bowel polyps. In a 10 year period (1976-85), 146 cases were recorded in the area. Age standardised incidence rates were 2.7 per 100,000 for men and 1.4 per 100,000 for women. Although incidence rates increased significantly during the study period, large bowel cancer diagnosed as a malignant polyp remained relatively rare (6.2% of all registered large bowel cancers). Two malignant polyps (1.4%) were less than 1 cm in diameter, 34 (23.3%) were more than 30 mm. Sixty patients were treated by endoscopic polypectomy, four by contact radiotherapy, 21 by surgical local excision, 58 by colectomy (10 preceded by polypectomy), and three by colotomy. Operative mortality was 8.2% after intra-abdominal surgery, 4.8% after local surgical excision, and 0% after polypectomy (p less than 0.05). All deaths occurred in patients over 65 years. The five year cumulative recurrence rates were 8.9% after surgical excision and 11.3% after endoscopic polypectomy (NS). The corresponding five year net survival rates were 86.1% and 95.9%. Endoscopic excision alone can be considered a sufficient treatment for adenomas with malignant change unless there is evidence of incomplete resection or a high risk of lymph node metastases.

[Digestive cancers in France. Comparison of the incidence in 7 departments and estimation of incidence in the entire country of France].

Estimation of differences in the incidence of digestive cancers in France was made from incidence data coming from 7 French departments covered by population-based registries. For some localizations, such as cancer of the pancreas, incidence variations could be explained by differences in recording techniques. But geographic variations clearly appeared for digestive tract cancers: the incidence of esophageal cancer is 4 to 5 fold less in the departments of Tarn and Haute-Garonne than in the department of Calvados. Conversely, the incidence of colorectal cancer is lower in the department of Calvados than in the others. For the entire country, the estimated number of digestive cancers is 46,300 cases per year. This number represents a third of all cancers in males and a fourth in females. Colorectal cancer (25,700 cases per year) is the most frequent of all cancers in both sexes. Cancer of the stomach (8,200 cases per year) is the second digestive cancer, equal to esophageal cancer in males. The heavy burden of digestive cancers in public health is emphasized by our results. These results should lead our country to intensify research in the direction of primary and secondary prevention.

[Role of deep temporal lift in the surgical treatment of face aging].

This is a new technique which is completely different from superficial temporal facelift also referred to as the mannequin facelift, which is associated with well known failures and sequelae. The principle of the deep temporal facelift is to approach the deep surface of the musculoaponeurotic plane by remaining in contact with the bone and to attach the ascension of this plane by means of sutures anchored to the temporalis mucsle and fibrin glue. This operation is technically possible due to the use of the dissectable space described by Rouvière between the galea and the temporalis muscle. This virtual, detachable space can only be easily defined by the use of hydrodissection. It is an avascular space with the exception of an unnamed vein located at the external agnle of the orbit. There is no resection of the scalp, no modification of the hairline and no modification of the sideburns. The frontal branch of the facial nerve constitutes the anatomical danger. It is situated anterior to the superficial temporoparietal aponeurosis which prolongs the galea. The two danger zones are the zygomatic arch which is crossed by the frontal nerve trunk and a quadrilateral area between the hairline and the tail of the eyebrow and a vertical line 1.5 cm lateral to the lateral canthus of the eye. The frontal nerve does not constitute any risk during deep temporal facelift, as this procedure remains about 1.5 cm away from the zygomatic arch. The nerve is obviously more superficial in the quadrilateral area. To avoid damaging it, the dissection must be performed under direct vision using a cold light, remaining in contact with the temporalis aponeurosis and avoiding any untimely instrumental manoeuvre between a subaponeurotic metallic instrument and the stretched skin. This technique causes minimal discomfort to the patient. It can be performed under local or general anaesthesia. The hospital stay is brief and the postoperative course is extremely straightforward with a very limited risk of bruising. The deep temporal facelift can be combined with the subpalpebral facelift in order to act on the upper 2/3 of the face. Its essential indications are: drooping of the tail of the eyebrow, drooping of the external canthus of the eye, erows feet.

[Cost of a mass screening program for colorectal cancer using the occult blood test].

The Cancer Registry of Burgundy, France, set up a controlled study involving 91,000 people aged 45 to 74 to ascertain the cost-effectiveness of mass screening for colorectal cancer with the Hemoccult test. The aim of this study was to estimate the cost of the first part of the screening campaign, which took place in 1988 and 1989. The overall cost of the campaign was 2,275,589 FF. The cost for the GPs' instruction course was 3.9 percent and the press campaign, 8.4 percent of total costs. The cost related to the distribution or prescription of tests by the GPs was 60.3 percent of the total cost of the campaign. The average cost per test was 39.8 FF when it was distributed by the GPs. The average cost per test was 116.4 FF when bought individually in drugstores or pharmacies. The average cost per test was 70.1 FF when mailing was used. The average cost per test for the analysis was 12.7 FF that is to say 13.7 percent of the total cost. The cost of scientific follow-up and analysis was 13.8 percent. The cost for one person completing the test averaged 92.7 FF. The preliminary results of the cost-effectiveness analysis make it possible to estimate the cost of the mass screening campaign for colorectal cancer. Better cost/effectiveness ratios have already been made according to these results.

[Multiple colorectal cancers. A population based study].

Data from the Registry of Digestive Cancers in the Côte-d'Or (France) concerning 2,174 colorectal cancers diagnosed between January 1, 1976 and December 31, 1985, and followed through December 31, 1987 enabled us to study the risk of a second synchronous or metachronous intestinal cancer occurring in a given population. Several simultaneous cancers were seen in 59 patients i.e. 2.8 per cent of cases. Diagnosis was made during the initial diagnostic phase in only 32 per cent of cases. Simultaneous cancers occurred preferably on the same colonic segment (kappa = 0.4) and the distribution of the principal tumour did not differ from that of the cancers occurring alone. When polyps were associated with the cancer, the risk of discovering a second synchronous lesion was multiplied by 3.8. Survival in single or multiple synchronous lesions was identical for the same cancer stage. Twenty cases of second metachronous cancers occurred during follow-up of a first colorectal cancer, the relative risk (RR) compared to the Côte-d'Or population was 1.4 (NS). The risk was significantly high for Dukes' stage A tumours (RR = 2.9; P less than 0.01), with an exophytic appearance (RR = 2.1; P less than 0.05) or with adenomatous remnants (RR = 3.4; P less than 0.01). These data suggest that complete examination of the colon should be performed when the diagnostic of colorectal cancer is made to look for an associated cancer or polyps. Follow-up surveillance should address mainly patients with Dukes' stage A or Dukes' stage B carcinoma with an exophytic appearance or adenomatous remnants.

The triple facelift. Current approach.

The combination of deep temporal facelift, subpalpebral facelift, and cervicofacial facelift constitutes the triple facelift. It exerts vertical traction with anchorage to solid anatomical landmarks, which permits perfect correction of ptosis. In addition, since this traction affects the upper two thirds of the face, the malar detachment of the cervicofacial facelift is considerably reduced or even nonexistent. Only the cervical phase is retained to reestablish the cervicomental angle. This technique, therefore, has the advantage of improving the quality of the result and reducing the postoperative course.

[Appendectomy, cholecystectomy, cholelithiasis and colorectal cancer. A retrospective case control study at the Côte-d'Or].

Several studies have shown that there might be a relationship between previous history of appendectomy or cholecystectomy and the subsequent risk of colorectal cancer. In order to investigate these hypotheses, a case-control study was set up to compare the history of appendectomy and cholecystectomy as well as the presence of cholelithiasis in patients with colorectal carcinoma vs patients with gastric carcinoma. The study was performed in the 727 patients included in the Registry of Digestive Cancers of the Côte d'Or and treated at the Dijon University Hospital during the period 1981-1987. These patients were well matched to those of the whole registry population for sex, age, stage, and residence distributions. In females, in comparison to the gastric cancer patients, a personal history of appendectomy was more commonly observed in case of right colonic cancer (odds ratio: 3.5; P less than 0.01) and a personal history of cholecystectomy in case of left colonic cancer, in particular when considering only those earlier than 10 years (odds ratio: 3.2; P less than 0.05). In contrast, the risk of rectal cancer was lower in case of a cholecystectomy performed more than 10 years earlier (odds ratio: 0.2; NS) and in case of cholelithiasis (odds ratio: 0.4; P less than 0.05). In males, there was no difference between cases and controls as for the proportion of appendectomies, cholecystectomies or cholelithiasis. These observations are consistent with the hypothesis that the appendix as a lymphoid organ plays a protective role in colon carcinogenesis, in particular in women.(ABSTRACT TRUNCATED AT 250 WORDS)

Participation in mass screening for colorectal cancer: results of screening and rescreening from the Burgundy study.

A controlled study was made in Burgundy (France) to assess the acceptability and efficiency of colorectal cancer screening using the Hemoccult test. A total of 91,000 people aged 45 to 74 years were included. The first screening campaign was made from January to July 1988 or 1989, and rescreening occurred from January to July 1990. During the first 4 months of the campaign, the General Practitioners (GPs) offered the test to their patients. It was then mailed to all subjects who had not completed it with a recall letter, if necessary, one month later. The overall compliance rate was 54.0% in the first campaign and 55.5% in the second campaign. A total of 63.7% subjects had completed at least one screening test over the two screening campaigns. Compliance was lower among men than women; compliance rate was also lower in the youngest and oldest age group than in the intermediate age groups. During the second screening campaign, the participation rate was 83.6% among participants in the first screening campaign and 20.9% among non-participants. Compliance during the medical offer phase was higher (81.4% during the first campaign, 82.9% during the second campaign) than during the postal offer phase (respectively, 33.8% and 28.5%). It was easier for GPs to propose the test when they had to offer it than when they had to prescribe it. These results suggest that a satisfactory participation rate can be obtained in France if GPs are actively involved in the screening programme. The final objective is to find a 25% difference in 5-year mortality by large bowel cancer between the screened and the test population.

[Incidence, diagnosis, treatment and prognosis of cancer of the pancreas: development in Côte-d'Or from 1976 to 1985].

The aim of this study was to analyze the epidemiological aspects of pancreatic cancers and their time trends in the Côte-d'Or population between 1976 and 1985. Over a period of ten years, 444 cases were diagnosed. The incidence rates standardized according to the world reference population were 8.2/100,000 in males and 3.8/100,000 in females. The Côte-d'Or is an intermediate risk area for pancreatic cancer. This cancer was slightly more common in urban than in rural areas (NS). The initially urban predominance of pancreatic cancer in males was no longer present 10 years later. Between 1976 and 1985, incidence of pancreatic cancer decreased by a mean of 4.7% per year in males (NS) and 0.5% per year in females (NS). A high proportion of the cancers (73.9%) were located in the head of the pancreas; among histologically confirmed cases, 69.7% were adenocarcinomas. Criteria for diagnosis evolved throughout the 10 years. The rate of histological confirmation increased annually by a mean of 3.0% (P less than 0.001). The relative importance among diagnostic procedures of direct biliary and pancreatic examinations decreased (P less than 0.05) whereas that of ultrasonography and radioscan increased (P less than 0.001). The overall surgical rate was 64.4% and the rate of curative surgery was 4.4%. The operability rate increased annually by a mean of 2.0% (NS). The overall survival rate was 13.2% after 1 year, 4.5% after 3 years and 3.2% after 5 years. Prognosis depended neither on age nor on sex or cancer location. The 5-year survival rate was 38.5% in the limited group of patients (n = 13) who underwent surgery for cure, and 0.0% in patients with palliative treatment. These data emphasize the severity of pancreatic cancers and the absence of any therapeutical improvement between 1976 and 1985 in spite of the evolution in diagnostic procedures.
