Two hundred and nineteen patients underwent gastrectomy for cancer in Nottingham University Hospital between January 1978 and December 1985. Twenty of these patients had early gastric cancer (EGC). Barium meal was performed in 15 patients and upper gastrointestinal endoscopy in 15. In all cases, barium meal failed to define the early nature of this disease. Only two lesions were thought to be EGC endoscopically and at laparotomy three were considered to be EGC. As neither radiologist, endoscopist nor surgeon can reliably identify EGC, all patients with gastric cancer in the absence of proven metastases should undergo gastrectomy.

A retrospective review of 176 patients with adenocarcinoma of the colon who underwent total colonoscopy preoperatively demonstrated synchronous carcinomas in 3.4 percent and synchronous polyps in 55.1 percent. Full-column barium enemas (68 patients) failed to identify cancer in 22 percent of patients and synchronous polyps in 58 percent of patients, a statistically significant (P less than 0.001) number of false-negative examinations. Double-contrast barium enemas (30 patients) failed to identify cancer in 27 percent of patients and synchronous polyps in 42 percent of patients, also a statistically significant (P less than 0.007) number of false-negative examinations. Full column and air contrast barium enemas identified all index cancers with distant metastases. Air-contrast barium enemas failed to identify 40 percent of "early" index cancers (confined to the bowel wall, negative nodes), and full-column barium enemas failed to identify 32 percent. The incidence of synchronous carcinoma and polyps underscores the need for total colon evaluation when a primary carcinoma is detected. Because of the poor accuracy of barium studies, total colonoscopy is the method of choice for this evaluation.

Six cases of malignancy (3 ovarian, 1 endometrial, 1 cecal, and 1 breast) were collected in which upper gastrointestinal (UGI) examinations revealed mass effect, nodularity, flattening, and/or spiculated mucosal folds on the greater curvature of the stomach due to contiguous spread of tumor from the greater omentum. Carcinoma of the transverse colon invading the stomach via the gastrocolic ligament may produce identical radiographic findings. In 3 cases, however, barium enema (BE) examinations revealed simultaneous involvement of the transverse colon by omental tumor as well as other evidence of intraperitoneal seeding. When a UGI examination suggests gastric involvement by omental metastases or so-called omental "cakes," a BE should be performed to demonstrate associated colonic involvement and to rule out a carcinoma of the transverse colon as the cause of these radiographic findings.

A case of seminoma testis with metastases to periurethral tissue and gastric submucosa is described. Response to treatment with irradiation and chemotherapy was good. Regression of the unusually sited tumour masses is demonstrated by barium meal and computed tomography. A brief review of gastric metastases is presented.

Thirty patients with early gastric cancer were studied as part of a consecutive series of 308 gastric cancers, giving a proportion of 9.7%. Twenty-eight of the early gastric cancer patients were symptomatic, pain being the most common symptom. Endoscopy proved more effective than barium studies as a first investigation but the diagnosis rate at first examination was still only 69%. Seven patients with early gastric cancer had lymph node spread at the time of presentation. Five patients eventually died of cancer metastases. There was a high incidence of benign peptic ulceration (50%) and this with lymph node metastasis was an unfavourable prognostic feature. Only four of the 26 patients submitted to standard surgical resections died of cancer. This study supports the concept that early gastric cancer does indeed occur in Western man and the five year survival rate (65%) is much higher than for late gastric cancer (13%). The high incidence of metastasis at the time of presentation may account for the difference between our survival rate for early gastric cancer, and that reported from Japan.

Prostate carcinoma occasionally can present with rectal obstructive symptoms and an annular constricting lesion of the rectum. Discriminating between primary rectal carcinoma and prostate carcinoma locally invasive to the rectum is of obvious importance because of the different treatments and prognoses. History and physical examination play only a marginal role in differentiating between these two lesions. The diagnosis of prostatic malignancy in patients in this circumstance can be supported by an elevated serum acid phosphatase as well as a bone scan that demonstrates a pelvic/vertebral distribution of bony metastases. The rectal mucosa is usually spared, and a barium enema often will demonstrate tapered margins as opposed to a tumor edge in primary rectal malignancy. Excretory urography often demonstrates hydronephrosis. Rectal biopsy with immunohistochemical staining for prostate specific antigen can direct the origin of a poorly differentiated adenocarcinoma to the prostate. Treatment involves hormonal manipulation with estrogen therapy or orchiectomy. Radiation therapy to the obstructed rectum has provided satisfactory palliation when hormonal manipulation fails.

Transhiatal esophagectomy without thoracotomy (THE) but with gastric interposition results in less morbidity and mortality than standard transpleural esophagectomy with thoracotomy. Barium examination has been the primary radiographic study following THE for detecting postoperative complications. We reviewed computed tomography (CT) scans of 21 patients who had undergone THE and correlated CT appearance with clinical status and with findings of the barium studies. Local mediastinal recurrent neoplasm was detected by CT in seven patients; barium study within 2 weeks of the CT scan failed to detect tumor recurrence in three of these patients. A mediastinal abscess well delineated by CT was percutaneously drained under CT guidance. Water-soluble contrast medium/barium study is preferable for the evaluation of certain postoperative complications such as anastomotic leak. However, CT is the modality of choice for detecting locally recurrent neoplasm and distant metastases following THE and may also be helpful in patients with postoperative mediastinal abscess. Normal mediastinal CT anatomy after esophagectomy is reviewed in order to warn against pitfalls in scan interpretation.

Fifty-nine patients with primary or recurrent carcinoma of the cervix were evaluated by computed tomography as part of their presurgical evaluation. The computed tomography staging results were compared with the surgical staging. Computed tomography staging was accurate in 71% (42 of 59), whereas clinical staging was accurate in 66% (39 of 59). In assessing paraaortic nodes by CT, there were 10 true-positive, 20 true-negative, 1 false-positive, and 2 false-negative results (sensitivity, 83%; specificity, 95%), for an overall accuracy of 91%. For pelvic nodes, there were 10 true-positive, 11 true-negative, 3 false-positive, and 6 false-negative results (sensitivity, 62.5% specificity, 78%), for an overall accuracy of 70%. Excretory urograms and barium enemas provided no information not obtained by computed tomography and are probably unnecessary if computed tomography is used as a routine staging examination. At present, computed tomography should not replace clinical assessment of extent of the disease. Its chief advantage over clinical staging is its ability to detect metastases beyond the true pelvis.

Squamous cell carcinoma of the colorectum is a rare pathologic curiosity. Since the first report by Schmidtman in 1919, only 69 cases have been reported in the English medical literature. The mean age at presentation is 52 years, and the disease presents itself equally in men and women. The rectum accounts for slightly less than one half of all cases. Survival appears to correlate with nodal status and findings of visceral metastases at presentation. Most tumors can be identified easily by physical examination and/or barium enema. Therapy is limited largely to surgical resection, although attempts at irradiation and chemotherapy have been made. At this time, the etiology of this disease process is unknown, but a likely explanation revolves around replacement of damaged epithelium by cells which undergo anaplasia due to repeated trauma. In addition to this review of the literature, the authors wish to add one additional report of a patient treated successfully by a multimodality approach.

A case of leiomyosarcoma of is reported. A 78-year-old man was admitted with a history of constipation and deformation of the stools. Barium contrast study and sigmoidoscopy showed a submucosal tumor of the rectum. On computed tomography and angiography, the tumor was suspected of being leiomyosarcoma. Abdominoperineal resection was performed. Microscopic examination revealed a leiomyosarcoma of the rectum and widespread lymph node metastases were found. Leiomyosarcoma of the rectum is an uncommon tumor. In our country, 89 cases have been reported. Six had lymph node metastases initially and another six subsequently. We have referred to the literature on leiomyosarcoma of the rectum.
