Clinical and morphologic factors that affected the distribution of disease are described in 100 cases of ovarian cancer at autopsy. In addition to the expected pattern of pelvic and abdominal peritoneal spread, extensive visceral parenchymal metastases were seen: liver parenchyma (45%), lung parenchyma (39%), small and large intestinal wall (52% and 55%), lymph nodes (70%), pancreas (21%), ureter (24%), bone (11%), and brain (6%). Liver parenchymal metastases replaced more than one third of the liver in 25% of cases, whereas lung metastases always involved less than one third of the lungs. When intestinal wall invasion was seen, bowel obstruction was present more often (71%) than when only intestinal serosa was involved (30%). Lymphatic invasion was predictive of lymph node, small intestinal wall, pancreatic, and liver as well as lung parenchymal metastases. Blood vessel invasion was predictive of pancreatic and ureteral metastases. Clinical stage I at diagnosis was associated with high incidences of liver parenchymal (56%), lymph node (56%), lung parenchymal (44%), large intestinal wall (33%), and bone (33%) metastases. Thus, ovarian cancer has parenchymal metastases similar to other carcinomas in addition to its peritoneal spread. Lymphatic and blood vessel invasion is predictive of such involvement. Intestinal wall invasion predicts bowel obstruction.

Cancer of the urinary bladder, renal pelvis and ureter is usually transitional cell carcinoma. One third of cases of urethral cancer are also transitional cell carcinoma. In planning the treatment for these urothelial cancers, the anatomic stage (Ta-T4), the histologic grade (1-3), tumor multiplicity and tumor size are generally taken into account. Superficial and low-grade tumors can usually be treated by transurethral resection. However, such patients run the risk of subsequent tumor recurrence in the bladder. This risk may be reduced by intravesical administration of anti-neoplastic agents and BCG. Diffuse carcinoma in situ (CIS) should be treated intravesically before deciding on surgical extirpation of the bladder. Patients with tumors showing deep muscle invasion are usually managed by surgery. The role of adjuvant chemotherapy and/or radiation therapy is currently under investigation. Patients with unresectable cancer and/or metastases are candidates for systemic chemotherapy. This form of therapy is now resulting in an increased number of complete and partial remissions. However, there is still no evidence that systemic chemotherapy prolongs the duration of survival, especially in patients showing partial remission.

Indirect mammo-lymphography with serial radiograms was made on rats bearing three established rat mammary carcinomas (SMT-2A, TMT-50, MT-W9B), with the water-soluble contrast medium, Iotasul. In the lymphogenously metastasizing SMT-2A, fine lymphatic sprouts from the tumor were seen converging into an afferent lymph vessel that was extending toward a metastatic regional lymph node, in 15-30 min. For 45 min, the dye remained localized in the primary tumor with no other vascular structures or viscera visible until it emerged in the urinary bladder, indicating that Iotasul was absorbed slowly into the systemic circulation via lymphatics and diluted beyond recognition by lymph and blood, and then reconcentrated in urine. In contrast, in the hematogenously metastasizing TMT-50, Iotasul was rapidly diffused into the blood stream, revealing the inferior caval vein within 5 min, and by 15 min the heart, aorta, common carotid arteries, kidney and ureter were all clearly revealed. In the non-metastasizing MT-W9B host, several small vascular markings around the tumor were seen by 10 min and the outline of kidneys and urinary bladder in 15 min, suggesting that the dye was also absorbed through blood capillaries but somewhat slowly. Thus, the differential vascular permeability in rat mammary tumors revealed by Iotasul has not only helped to distinguish lymphatics from blood vessels, but also to correlate it with their metastatic potential.

The following question was to be resolved: In view of the usually only minimal involvement (7.9%) of the parametria in stage Ib cervical cancer (CC Ib), is their complete removal necessary in such cases? Experience has shown that exposure can lead to subsequent impairment of the ureter, the bladder, and the rectum. Consequently, between 1971 and 1979, CC Ib was treated surgically in an alternating pattern: either after Wertheim-Meigs (WM) (108 cases in all), or after Galvin-TeLinde (GT), that is to say, with retention of the parametria to a large extent (102 cases in all). Results of histological study of the surgical specimens revealed approximately the same material in the two groups. Postoperative irradiation was performed in approximately 50% of the patients in both groups. In both groups, the frequency of metastases and recurrence was around 20%. In 1983, the evaluation of all the cases revealed a survival rate of 72.3% in the WM group, and of 78.5% in the GT group. The frequency of fistula and complaints in the GT group was only about one third of the found in the WM group. From their investigations, the authors conclude that the parametria do not have to be removed completely in cases of CC Ib, since late results are just as good with this limited operation as with Wertheim-Meigs' radical operation, yet with fewer complications. The removal of the affected uterus together with the pelvic lymph nodes and the extirpation of a vaginal cuff should be obligatory.

CT findings in three cases of ureteral metastases are reported. Metastases to the ureter is an uncommon cause of the upper urinary tract obstruction. The most common primary sites include breast, stomach and neoplasms from pelvic organs. Radiographic studies revealed an ureteral stenosis in all the presenting cases. CT scans demonstrated a thickened regular ureteral wall at the level of the narrowing and no other abnormalities of the retroperitoneum. Such CT features suggest the possibility of ureteral metastases in a patient with the appropriate clinical setting. Histological studies, whenever possible, must confirm these radiographic findings. Early recognition of ureteral metastases and appropriate treatment for relief of urinary tract obstruction may prolong survival time.

A 9-year review of our experience with head and neck metastases from 845 urogenital tract tumors of the kidney, prostate, bladder, testicle, spermatic cord, penis, urethra, and ureter was performed. Thirty-one (3.7%) of these tumors developed metastases to the cervical and supraclavicular lymph nodes, scalp, thyroid gland, thyroid cartilage, parotid gland, retroorbit, mandible, nasal cavity, and paranasal sinuses. Unusual cases and a review of the literature are presented. The frequency of such metastases to the head and neck from various primaries, diagnostic application of current immunohistochemical methodology, and therapeutic alternatives are emphasized.

The indications and possibilities of radiotherapy in carcinomas of the renal pelvis and the ureter are demonstrated. Based on the literature and our own experience in 22 cases, postoperative radiotherapy should be performed in cases of deep infiltrating carcinomas, after subtotal surgery, and in cases with lymph node metastases. The radiation dose applied should be 50-55 Gy to the tumor bed and 45 (-50) Gy to the regional lymph nodes. Local recurrences can be greatly diminished without severe complications. Therefore, postoperative radiotherapy in carcinomas of the renal pelvis and the ureter can be recommended.

Wertheim radical hysterectomy combined with pelvic lymphadenectomy was performed at the Helsinki University Central Hospital on 132 women of whom 120 had cervical carcinoma from Stage IA to early IIB and 12 had endometrial carcinoma Stage II. None of the patients died or had severe complications during their hospitalisation. The left ureter was accidently transected in two patients and both were corrected immediately. Wound complications occurred in 16 patients (12%). The high incidence of wound complications is probably partly related to the low-dose heparin prophylaxis. The initial clinical staging was found to be correct in 85% of the cases. Five cases were under-staged. All ten patients cases of early Stage IIB were over-staged, none of whom had parametrial invasion. The predictive value of lymphangiography was low, 14% in histologically positive cases and 89% in negative cases of lymph node metastases. Lymphangiography proved to be only of value in facilitating complete lymph node dissection. Intra-operative lymphangiographic control revealed radio-positive nodes and lead to further dissection in 30 patients (24%).

A screening test for detecting antibodies to HSV-TAA was performed on 26 sera, from urinary bladder carcinoma patients and on 30 sera from prostatic carcinoma patients. Positive results were found in 50% of the urinary bladder cancer sera and in 60% of the prostatic carcinoma sera. As control 10/11 sera from benign prostatic hypertrophy and 4/4 sera from renal pelvis or ureter neoplasias (tumors never previously associated to HSV) were negative before and after surgery. The only one positive of the former group became negative after surgical treatment. The TAF-test can therefore be a meaningful test for monitoring antibody levels in the sera of patients before, during or after the treatment, in order to evaluate the presence of metastases or the success of a therapy.

Metastatic carcinoma to the testis is unusual. There are only seven previously reported cases in which a testicular mass was the first clinical manifestation of an underlying malignancy. The authors review 127 cases in which the testis was involved by metastatic carcinoma, and describe an additional two patients in whom a malignant testicular mass was the presenting sign of an underlying nontesticular carcinoma. The tumors most commonly reported to metastasize to the testis are: prostate (45 cases), lung (25 cases), melanoma (12 cases), colon (11 cases), kidney (10 cases), stomach (6 cases), and pancreas (5 cases). Neuroblastoma, retinoblastoma, carcinoid tumor, and cancers of the bile duct, ureter, bladder, salivary gland, and thyroid have also involved the testis secondarily. Nineteen patients (15%) had bilateral testicular metastases. Patients with secondary testicular neoplasms were older in general than those with germ cell tumors (mean, 55 years; median, 57 years). Histologically, the presence of extensive lymphatic and vascular invasion and an interstitial pattern, in which the seminiferous tubules are spared, is suggestive of a metastasis. In four of the nine cases (44%) in which testicular enlargement was the first manifestation of an underlying carcinoma the correct pathologic diagnosis was initially missed. Serum alpha-fetoprotein (AFP) and human chorionic gonadotropin (HCG) are occasionally elevated in patients with nontesticular primary tumors, but markedly elevated levels in young patients suggest a nonseminomatous germ cell tumor, as does positive immunoperoxidase staining for AFP and HCG.
