Two hundred thirty two patients with rectal cancer at or below the peritoneal reflection, who underwent extended systematic lymphadenectomy, especially lateral node dissection, were reviewed with respect to survival rate, degree of surgical technique, and mode of recurrence. On the basis of the extent of lateral node spread, two types of lateral node dissection were performed, consisting of preservation of internal iliac vessels (conventional) and en bloc excision of these vessels (extended). The overall disease-free five-year survival rate was 69.4 percent in all patients--75.8 percent for those who underwent extended resection and 67.4 percent for those who underwent conventional resection an excellent survival rate of 49 percent of patients with lateral node metastasis was obtained. The analysis was carried out with regard to prognostic factors such as number of node
metastases
, obesity index, mode of recurrence, etc. We would recommend that systemic lymphadenectomy with lateral node dissection be performed for advanced rectal cancer at or below the peritoneal reflection.

The management of patients with invasive carcinoma removed by colonoscopic polypectomy remains controversial. In order to assess the criteria for subsequent surgery after polypectomy, the histologic findings and outcome of 25 patients with invasive carcinomas treated by polypectomy were analyzed. Subsequent surgery was indicated when removed invasive carcinoma showed at least one of the following findings: 1) carcinoma near the surgical margin, 2) vessel invasion, 3) massive invasion, and 4) poorly differentiated adenocarcinoma. The authors considered those findings to be a risk factor for local residual carcinoma or lymph-node
metastases
, or both. Of 25 patients, 18 showed risk factors, with 16 receiving surgery. Only one had residual carcinoma in the lymphatic vessel of the surgical specimen. The remaining 15 had no carcinoma in the surgical specimens, however, one died of recurrent disease 55 months later. Two patients with risk factors received no surgery for various reasons. Local recurrent carcinoma developed in one 39 months later and the other had no recurrent carcinoma at autopsy. Seven patients without risk factors were adequately treated by polypectomy without recurrent disease 34 to 96 months later (average, 69 months). Consequently, of 18 patients with risk factors, 3 showed either residual carcinoma in the surgical specimens or recurrent carcinoma was found later. None of 7 patients without risk factors developed recurrent disease. We recommend that patients with risk factors be followed by surgery; however, patients without risk factors can be adequately treated by polypectomy alone.

To assess prognostic factors in patients who develop colorectal cancer before the age of 40 years, a 30-year experience from 1956 through 1985 was reviewed. There were 50 patients ranging in age from 7 to 39 years. Five cases were associated with either ulcerative colitis (2) or familial polyposis (3). The most common presenting symptoms were abdominal pain (66 percent), hematochezia (60 percent), change in bowel habit (41 percent) and weight loss (30 percent). On pathologic staging (N = 44), only 14 of 44 (31 percent) had a Dukes' stage A or B lesion, 20 (45 percent) had Dukes' stage C, and the remaining 10 (23 percent) had distant
metastases
at the time of surgery. Five-year survival rate was 28 percent with a disease-free survival rate of 18 percent. Median survival was only 28 months. Negative prognostic factors were Dukes' stage C/D (P less than .001), symptom duration of longer than 3 months (P = .01), noncaucasian ancestry (P = .01), and poorly differentiated histology (P = .06). In contrast to older patients with colorectal cancer, only 1 of 30 (3 percent) patients with stage C D disease was disease-free at 5 years. In view of the poor survival rate associated with both delay in diagnosis and the presence of advanced disease, it was concluded that young patients presenting with the symptoms listed above need early, aggressive evaluation for possible colorectal cancer.

Thirty-nine patients (age 40 years and younger) with rectal cancer treated at the Mount Sinai Hospital between 1967 and 1985 were studied. Their mean age was 34 years (range, 21 to 40). A positive family history for colorectal cancer was found in six patients (15 percent). Fifty percent of patients under age 30 had
metastatic disease
at diagnosis. Twenty-seven patients (69 percent) had potentially curative resections. Of these, 17 (63 percent) had lymph-node metastasis. This rate is twice as high as in a group of 315 patients with rectal cancer over age 40 (31 percent). The overall five-year survival for young patients having curative resection was 53 percent. Noncolorectal cancer occurred in three patients in this series and six patients also had first-degree relatives with noncolorectal cancer. Young patients with rectal cancer appear to belong to a high-risk cancer group which often seems to have a genetic pattern of predisposition.

Metastasis
from colorectal carcinoma occurs by either lymphatic or hematogenous spread. The pattern of metastasis in patients with colorectal malignancy has been characterized by numerous clinical, surgical, and autopsy studies. The most common sites of colorectal metastasis are the liver and lung. Only two previous instances of colorectal carcinoma metastatic to skeletal muscle have been reported. The present report documents the third case of colorectal cancer metastatic to skeletal muscle and reviews the typical pattern of distant metastasis from colorectal carcinoma.

Of 518 patients undergoing the ileal pouch-anal anastomosis (IPAA), 17 (13 with chronic ulcerative colitis [CUC] and four with familial polyposis coli [FPC] ) also had a total of 22 cancers of the colorectum. Tumors were concentrated distally (rectum 6; sigmoid colon 5; proximal colon 11) and were diagnosed preoperatively in eight patients. Histologic grade and stage were as follows: grade I, 36 percent; II, 23 percent; III, 23 percent; IV, 18 percent; stage A, 5 percent; B1, 32 percent; B2, 18 percent; C1 and C2, 45 percent. Median hospital stay was 17 days with no operative mortality. Relaparotomy was required in 35 percent (sepsis in four patients; obstruction in two) and minor procedures were done in 12 percent (anastomotic dilatation in one; rectovaginal fistula in one). Mean frequency of defecation was 6.4/day, 1.0/night; incidence of minor seepage, 17 percent (day), 50 percent night); incidence of pouchitis, 8 percent; intermittent dyspareunia, 17 percent of six women. One patient died from hepatic
metastases
nine months after operation. IPAA should be considered in favorable cancers complicating CUC or FPC, although it may be contraindicated in advanced rectal cancer, and may be unsuitable in advanced proximal cancer.

A previously unreported complication of low anterior resection of the rectum, seminal vesicle-rectal fistula, was encountered one month after surgery in an elderly patient with adenocarcinoma of the midrectum. Antibiotic-induced colitis in the immediate postoperative period led to anastomotic leakage with abscess formation and ensuing fistulization to the surgically denuded right seminal vesicle. Pneumaturia, bacteriuria, and right testicular pain were treated by cutaneous vasostomy and antimicrobial therapy. Despite recurrent low-grade urinary sepsis controlled by alternating courses of various antimicrobials, and radiation therapy for local tumor recurrence, the patient remained reasonably healthy until his death two years later due to stroke associated with cerebral
metastases
.

Continuous chemotherapy for hepatic
metastases
secondary to carcinoma of the colon and/or rectum was delivered via implantable pump in 20 patients. This is a follow-up to a preliminary report published in January 1985. Pumps were placed by a single surgeon in a community hospital; there was no mortality and minimal morbidity. Follow-up of these patients revealed a significant long-term complication rate secondary to effects of chemotherapy. Nine patients were alive at the cutoff date of this report; mean follow-up was 16 months. Eleven patients have died following implantation, with a mean survival of 14 months. Statistical analyses demonstrated increased survival rates for those patients whose tumors were poorly differentiated when compared with those with moderately differentiated or well-differentiated tumors. The objective response of liver metastases was overwhelmingly positive, as judged by CT scan and serial CEA levels. The significant rehospitalization rate for complications and the marginal increase in survival, however, have discouraged implantation of the pump at our institution.

Small-cell carcinoma of the rectum is a rare tumor. We treated a patient with small-cell carcinoma of the rectum with radiation and multidrug regimen being used for small-cell carcinoma of the lung. Within two months of chemotherapy, the primary lesion, as evaluated by rectoscopy, biopsy, and CT scan, had resolved completely. The patient was in complete remission for 12 months after initiation of chemotherapy and died of widespread
metastases
. At autopsy, no residual tumor was found in the rectum. This case stresses the importance of ultrastructural study in the differential diagnosis of small-cell cancer of the rectum and the fact that this tumor can be treated in the same fashion as for small-cell carcinoma of the lung with multidrug chemotherapy and radiation therapy to achieve local control.

Over the past 11 years (1974 to 1985) ten patients with perianal Paget's disease were treated. The average age was 64 years and half were male. Two patients were diagnosed as an incidental finding after hemorrhoidectomy and the remainder presented with a symptomatic perianal rash (itching and moisture) that averaged two years in duration. Physical examination in these patients demonstrated characteristic lesions (seven with erythematous or ulcerated, whitish gray lesions and one with a papillary lesion). Three patients presented with invasive carcinomas and, despite aggressive therapy, all developed
metastatic disease
. Two patients had local excisions with minimal margins and developed associated invasive cancers at four and ten years after diagnosis. The remaining five patients were treated by wide local excision and skin grafts. At present all are free of disease. The characteristic appearance of this lesion and its failure to respond quickly to conventional therapy should lead the clinician to obtain a biopsy which readily establishes the diagnosis. Experience confirms that wide local excision is adequate therapy, but adequate initial evaluation and close follow-up are necessary to identify other malignancies that may develop.
