Twenty-year follow-up of the breast cancers diagnosed during the Breast Cancer Detection Demonstration Project.

This study reports on the 20-year follow-up of the women diagnosed with breast cancer in the Breast Cancer Detection Demonstration Project (BCDDP) between 1973 and 1980. This project provided 5 years of screening with physical examination and two-view mammography for 280,000 volunteer women across the United States. Based on a 96% follow-up from 1993 to 1995 of the 4,051 women with breast cancer available for analysis, 2,658 (66%) were alive and 1,393 (34%) were dead. A high proportion of the cancers were detected by mammography alone, and 28.6% of all the cancers were smaller than 1.0 cm. Survival rates were calculated by life table method with deaths from breast cancer as the outcome. The adjusted survival rate for the entire group was 80.5%, and the observed survival rate was 61.7%. Adjusted and observed survival rates were 97.2% and 78.5%, respectively, for women with non-invasive cancers and 78.2% and 59.3%, respectively, for those with invasive cancers. Lymph node status and the size of the cancer at diagnosis were prognostic indicators of survival in the BCDDP Women with invasive cancers and negative lymph nodes had an 85.5% breast cancer survival rate and a 65.6% observed survival rate. Adjusted survival rates for women with invasive breast cancers were 90.2% for cancers smaller than 1 cm, 80.5%, for cancers 1.0 to 1.9 cm, 70.5% for cancers 2.0 to 4.9 cm, and 60.6% for cancers larger than 5 cm. Women 40 to 49 years of age demonstrated a greater survival with noninvasive or invasive cancers smaller than 5.0 cm compared with women 50 to 59 and 60 to 69 years of age at diagnosis. These results from the BCDDP are discussed in the context of the recent decline in breast cancer incidence and mortality in the United States.

Surgical techniques of the modified radical mastectomy for the treatment of breast cancer.

Although the clinical status of each patient must be dealt with in an individual fashion, we continue to favor the modified radical mastectomy as described in the overwhelming majority of patients we see with proven carcinoma of the breast.

Quality of life after Brooke ileostomy and ileal pouch-anal anastomosis. Comparison of performance status.

Although the clinical results of Brooke ileostomy are good, patients are permanently incontinent of stool and gas. Alternative operations designed to restore enteric continence, such as ileal pouch-anal anastomosis, must not only be as safe and effective as Brooke ileostomy, but should provide an improved quality of life in order to establish long-term acceptability. Ileal pouch-anal anastomosis has been performed safely and good functional results have been reported. The quality of life after ileal pouch-anal anastomosis, however, has not been documented. Two hundred ninety-eight ileal pouch patients and 406 Brooke ileostomy patients who had the operations performed for chronic ulcerative colitis or familial adenomatous polyposis formed the basis of the study. After adjusting for age, diagnosis, and reoperation rate, logistic regression analysis of performance scores in seven different categories was used to discriminate between operations. Median follow-up was longer in Brooke ileostomy patients than in ileal pouch patients (104 months vs. 47 months, respectively), and Brooke ileostomy patients were slightly older (38 years vs. 32 years). A great majority of patients in each group were satisfied (93% Brooke ileostomy; 95% ileal pouch-anal anastomosis). Thirty-nine per cent of Brooke ileostomy patients, however, desired a change in the type of ileostomy they had. At 47 months, ileal pouch patients had a median of 5 stools per day and 1 at night, 77% did not experience any daytime incontinence, while 22% reported occasional spotting. In each performance category, the performance score discriminated between operations, with the probability of having had an ileal pouch-anal anastomosis operation increasing with improvement in performance scores (p less than 0.05). We concluded that after ileal pouch-anal anastomosis, patients experienced significant advantages in performing daily activities compared to patients with Brooke ileostomy and thus may experience a better quality of life. These results help further to establish ileal pouch-anal anastomosis as a safe, attractive, and valid alternative to Brooke ileostomy.

Modified and complete neck dissection in the treatment of squamous cell carcinoma of the head and neck.

The relative merits and indications for complete or modified dissection of the neck are straightforward. Which operation is selected centers on the perception of the value of the preservation or the risk with the loss of one or more of three structures: the spinal accessory nerve, the internal jugular vein and the sternocleidomastoid muscle. If these were the only issues, the choice of operation would be easy. Unfortunately, some of the most contentious issues in treatment of metastasis to the neck have been linked with the concept of the modified neck dissection. Such issues as combined multimodality therapy, preoperative and postoperative radiation therapy or surgical treatment alone, prophylactic dissection and bilateral simultaneous dissection of the neck are rightly or wrongly tied in with the type of dissection of the neck. More information, such as the certainty of the real risk factors in the neck with metastatic disease, the real value, if any, of adjunctive combined therapy and basic information about the role of the nodes in the neck, is necessary before the debate on the modified versus the radical dissection of the neck will end.

Continent ileostomy and ileoanal procedures.

It is fortunate today that several alternatives are available for reconstruction of the intestinal tract when proctocolectomy is required in the management of inflammatory diseases of the colon or multiple neoplastic diseases. The Brooke ileostomy proves to be very satisfactory and is acceptable to the majority of patients but does require the continual wearing of an appliance. For patients with chronic ulcerative colitis and a poorly functioning anal sphincter or one that is diseased, a continent ileostomy is the preferred procedure. However, in patients with a normally functioning anal sphincter, an ileoanal anastomosis, most often with a "J" pouch, is the first alternative procedure to be considered because evacuation following this operation is through the normal route and requires no equipment. For patients with granulomatous colitis (Crohn's disease), it seems best to consider only the Brooke type of ileostomy because of the risk of recurrent inflammatory disease involving the ileum. However, for colonic ulcerative colitis and familial polyposis, either the continent ileostomy or the ileoanal anastomosis is the preferred procedure to be considered. Dozois has reviewed in detail the technical aspects of the various surgical procedures, the indications for their use, the results that can be expected, and the comments of many of the contributors to the advances in the management of patients requiring proctocolectomy and one method or another of re-establishing a means for bowel evacuation. With the various alternatives that are available today and the excellent results that can be expected when patients are properly selected, more patients with diseases of the colon and rectum requiring proctocolectomy can be offered the benefits of surgical treatment, returning them to society and improving their quality of life.
