Therefore, total cystectomy and bilateral ureteroileal anastomosis with cutane- ous ileostomy was carried out on March 9, 1959. The preoperative intravenous urogram showed nor- mal upper urinary tract architecture bilaterally with no evidence of ureteropelvic filling defects. After the operation, electrolyte and creatinine de- terminations remained within normal limits. With the exception of one episode of pyelonephritis characterized by chills and fever and responding promptly to sulfonamide therapy, the patient re- mained well until in May of 1961 he noticed blood in the urine. There was no pain associated with the gross hematuria or with the passage of clots. Whereas intravenous urograms on March 20, 1959, were normal, a pyelogram on May 15, 1961, showed filling defects in the pelvis of the right kidney and suggested papillary pelvic tumor (Figure 1). Papa- nicolaou study of the urine showed class II atypical cells, not suggestive of malignant disease. On May 24 the patient had severe right flank pain and gross hematuria.

The ureter was removed flush with the ileum. The postoperative course was uneventful and the patient was discharged on the eighth postoperative day. The pathologist reported transitional cell carci- noma of the inferior calyx of the right kidney with extension to the ureter (Figure 3). Metastatic tran- sitional cell carcinoma was found in one of four hilar lymph nodes. The kidney showed chronic and acute pyelonephritis and the ureter chronic and acute ureteritis with ureteritis cystica. The patient thereafter was examined regularly in the outpatient department. The gross renal function and electrolytes always were within normal limits, as was an intravenous urogram shortly before the time of this report. Although the patient has sur- vived one year since right nephrectomy, the prog- nosis is obviously poor. CASE 2. A 70-year-old white man was admitted to the Veterans Administration Hospital in Los An- geles on April 25, 1957, because of obstructive uri- nary symptoms. He was found to have moderate prostatic enlargement and a fungating lesion on the floor of the bladder. Blood creatinine was within normal limits and no abnormalities were seen in roentgen examination of the chest and bones. An intravenous urogram disclosed a duplex collecting Figure 4.- (Case 2) -Normal intravenous pyelogram system on the right with ureteral duplication down taken in December of 1957.

The bladder tumor was removed by transurethral resection and the pathologist reported grade II tran- sitional cell carcinoma with no evidence of muscle invasion. Two weeks later, transurethral resection of the prostate was done. In July 1957, transurethral resection of a recur- rent bladder tumor was done. The diagnosis was transitional cell carcinoma grade II of the urinary bladder. Another recurrence in November 1957 was treated by transurethral resection. In 1958, cystos- copy showed an extensive bladder tumor about the left ureteral orifice. On this occasion, biopsies showed transitional cell carcinoma, grade II to III. No mass was felt on bimanual examination. Because of the progressive frequency and size of the recur. rences, cystectomy and ureteroileal anastomosis with ilealcutaneous conduit were done.

Tissue examina- tion of the kidney showed infiltrating transitional cell carcinoma, grade IV, extending from the renal pelvis down the ureter (Figure 7). Two lymph nodes showed diffuse tumor metastasis (Figure 8). It was decided to give no irradiation therapy postopera- tively. At last report, eight months following left nephrectomy, the patient's weight was being main- tained at 105 to 110 pounds and he had no com- plaints. However, the outlook was considered dismal. DISCUSSION The prognosis of papillary tumors of the renal pelvis and ureter has been spectacularly improved by application of complete nephroureterectomy. This was emphasized by O'Connor.8 Kaminsky also stressed that the tendency of pelvic ureteral tumors to spread by reimplantation dictates nephroureterec. tomy.5 He also posed a question as to whether spread is direct or by lymphatic channel. Probably in our cases, lymphatic spread would be the most likely, for two reasons. First, the lymphatic pathway is from the bladder to the area of the renal pelvis. Second, in both cases the lymph nodes were in- Figure 8.-( Case 2)-Photomicrograph (X250) of volved with tumor. lymph node showing tumorous involvement.

  • Radical Abdominal Hysterectomy
    GYNECOLOGIC ONCOLOGY 00394109/01 $15.00 + .OO RADICAL ABDOMINAL HYSTERECTOMY Nadeem R. Abu-Rustum, MD, and William J. Hoskins, MD Radical abdominal hysterectomy was developed in the late nineteenth cen- tury for the treatment of cancer of the cervix uteri and upper vagina. The procedure was originally described in 1895 by Clark and Reis,3°,39but Wertheim is credited for the development and improvement of the basic technique of radical hysterectomy. Wertheim reported extensively on his early results with this procedure and was a pioneer in describing approaches to reducing problems with hemorrhage, urinary tract injury, fistula formation, and sepsis3 Over the past century, the procedure underwent several refinements in indications, patient selection, and surgical technique. Moreover, the advancements in anesthesiology, antibiotics, and preoperative and postoperative medical care have resulted in a significant reduction in morbidity and mortality from this procedure. Several competitors to radical abdominal hysterectomy have emerged over the years. Radiotherapy, discovered around the time that radical hysterectomy was being developed, continues to be used for the treatment of patients with advanced-stage (International Federation of Gynecologic Oncology [FIGO] stages IIB-IV) and selected patients with early stage cervical cancer. Further- more, radical vaginal hysterectomy (Schauta-Amreich) has seen a recent revival since its early description, mainly because of the advancements in laparoscopic pelvic and paraaortic lymphadenectomy, which would accompany the vaginal resection of malignancy. In addition, laparoscopic radical hysterectomy and fertility-sparing radical transvaginal trachelectomy (i.e., removing the cervix and preserving the corpus) with laparoscopic pelvic lymphadenectomy are among the newest techniques to compete with the classic radical abdominal hysterec- tomy for the treatment of early cervical cancer.

  • Malignant Mixed Tumor of the Thyroid Gland with Skeletal Muscle Fibers
    MALIGNANT MIXED TUMOR OF THE THYROID GLAND WITH SKELETAL MUSCLE FIBERS EDWIN F. HIRSCH, M.D. (From the Henry Baird Favill Laboratory of St. Luke's Hospital, Chicago, Illinois. Aided by the Watson K. Blair Memorial Research Fund) Malignant tumors with an intimate mixture of cellular com­ ponents from two germ layers, such as epithelium and mesothelium, in varying proportions, are of special interest because of their rarity, and because their tissues contain surprising and bizarre combinations of cell structures. Such tumors originating in the thyroid gland, in the mammary gland, and elsewhere, have been reported as carcinosarcomas (Mason and Wells; Ktichens; Saltykow). Wegelin's recent review of these tumors of the thyroid mentioned only a few, and the structure of these varied con­ siderably. Antedating Wegelin's review by several years was the report by Schuppisser in which he stated, as have others, that true carcinosarcomas of the thyroid are rare. He mentioned the two tumors reported by Forster, those reported by Kocher, Jr., Simmonds, Albrecht, and Schmorl, and one in a dog reported by Wells. These summarizing statements and those in the recent account by Mason and Wells indicate how few indeed are the reports of malignant mixed cell tumors of the thyroid. The variations in histologic structure seem to depend upon the degree of differentiation of the epithelial and mesothelial tissues and the proportion of each entering into the composition of the primary growth and its metastases. Some of the accounts report a fairly complete separation of the tissue derivatives in the primary growth, in the recurrence, or in the metastases, so that in these various places elements of only one of the two germ layers were found.

SUMMARY A case of ependymoma of the cauda equina, presumably originating from the filum terminale in a girl aged 17 at the onset of illness, eventually developed remote metastases in the lungs, pleura, and one para-aortic lymph node. This case is compared with three other previously reported examples. The unusual features in the present instance were (1) the total length of the clinical history, amounting to 29 years; (2) the development, six years after the removal of the original spinal tumour, of another ependymomatous mass in the fourth ventricle, interpreted as a rostral metastasis that seeded via the cerebrospinal fluid; and (3) the demonstration of anaplastic cytological changes at the primary site, interpreted as the result of irradiation.

Current treatments include Lymph node involvement denotes a poor outcome for patients radical prostatectomy, usually with pelvic lymphadenectomy for with prostate cancer. Our group, along with others, has shown lymph node assessment, followed by radiation or hormone therapy that initial tumor cell dissemination to regional lymph nodes (4). There are currently no effective treatments for recurrent or via lymphatics also promotes systemic metastasis in mouse metastatic disease, highlighting the importance of alternative models. The aim of this study was to investigate the efficacy of strategies for early intervention. suppressive therapies targeting either the angiogenic or Angiogenesis is essential for the growth of solid cancers beyond lymphangiogenic axis in inhibiting regional lymph node and 2 mm, which is the limit of nutrient diffusion (5). This process also systemic metastasis in subcutaneous and orthotopic prostate clearly contributes to metastasis of most solid cancers.
