Three clinico-pathological cases of necrotic myelopathies with a distant malignancy are presented. Two cases had a lymphosarcoma and one case a prostatic carcinoma. They were compared to 13 well studied other cases collected in the literature. These myelopathies were related to solid visceral tumours in 8 cases and to lymphomas in 5 cases. The disease could be individualized on clinical grounds (flaccid paraplegia with bladder and bowell incontinence and sensory loss without clear-cut upper boundary developing over a few weeks with normal CSF and fast impairement of general condition), and, on pathological features. It is characterized by one or several spinal cord necrosis areas, often asymetrical, involving mostly white matter, without any vascular topography. Axons are involved as well as myelin sheats. There is mild inflammation and no specific vascular alteration. There is no metastases in the cord, meninges, vertebral column or nerve root. No vascular occlusion is found. The mechanism of the disease is unknown. The frequent occurence of lymphomas could suggest the presence of immunopathological factors.

Ultrastructural and histological investigations were performed on a case of generalized melanosis associated with superficial spreading melanoma. The hyperpigmentation of the general body surface, mucous membranes and nail beds was associated with deposition of melanin in macrophages in the dermis, together with some hyperactivity of epidermal melanocytes. Melanin granules were observed lying free in the stroma, suggesting pigment incontinence and phagocytosis by macrophages. Giant melanosomes were noted in melanocytes, keratinocytes and melanophages in the hyperpigmented skin. No evidence was found to suggest dissemination of individual malignant cells throughout the skin. Subcutaneous nodules of malignant melanoma were, however, present, as well as metastases to the iris, liver and to other organs.

A 43-year-old woman presented with incontinence, weakness, and paresthesia, consistent with the cauda equina syndrome, 10 years after having a pituitary tumor surgically removed and 4 years after excision of two "meningiomas" of the cervical cord. The patient was also hypertensive and had a cushingoid habitus. Emergent surgical decompression of the spinal cord revealed intradural metastatic adrenocorticotropic hormone-producing pituitary carcinoma. Pituitary carcinomas are rare. The majority of reported cases of adrenocorticotropic hormone-producing carcinoma have exhibited metastases outside the central nervous system. To our knowledge, this represents the first case of an adrenocorticotropic hormone-producing pituitary carcinoma presenting with the cauda equina syndrome. A review of all reported cases of pituitary carcinoma indicated that central nervous system metastases were more common than metastases to distant sites, and patients with distant metastases experienced a shorter duration of disease than did those with central nervous system metastases.

A total of 25 patients at least 75 years old underwent continent urinary diversion via a modified Indiana Pouch during a 68-month period, 21 of these with simultaneous radical cystectomy or anterior exenteration. The preoperative medical conditions as well as the early and late operative morbidity and mortality are reviewed with a mean follow up of 27 months. Average age of patients was 78.5 years, and the mean age of survivors is 81 years. There were two early mortalities attributed to ileal gangrene with secondary sepsis and aspiration pneumonia. Postoperative complications (superficial wound infection, middle colic vein bleed, right ureteral leak, ileus) occurred in five patients, two of whom required re-operation. Mean hospital stay was 12.4 days and ranged from 9-20. There were only six late complications [ureteral stricture (3), small bowel obstruction (1), incontinence (1)] necessitating re-hospitalization and surgical intervention. Late infectious complications included recurrent urinary tract infections (3), pyelonephritis (2), and C. Difficile enterocolitis (2) all managed medically. In addition, 10 other patients have died, 9 from metastatic disease and 1 from intercurrent medical problems. Of the 13 remaining patients, 11 are disease free and all are continent with a mean follow-up time of 33 months. We conclude that continent urinary diversion via a modified Indiana pouch with radical cystectomy or anterior exenteration can be performed with minimal morbidity or mortality, even in an elderly population.

We report about one case of spontaneous healing of metastases of kidney cancer (hypernephroma). The subcutaneous and abdominal metastases appeared 3 years after the discovery of the initial neoplasm and subsequent nephrectomy. Meanwhile the patient developed an adenoma of the prostate, while the neoplasm was in a metastasizing stage. After prostatectomy, he was treated with Ephynal for mild transient incontinence. From then on, we witnessed progressive disappearance of the metastases, until they were completely eradicated. This case is very well documented, with irrefutable histological evidence of the nature of the lesions and of their healing. It adds to the 21 similar cases published worldwide until then. In recent cases, the beneficial role of vitamin D in the treatment of metastases of kidney cancer has been predicted. We have probably demonstrated accidentally that vitamin E, which has some similarities with vitamin D, is a least as effective. In addition, it is a particularly innocuous and cheap medication. This may be an interesting therapeutic improvement, considering that there is no really effective treatment of metastasized kidney cancer, except very heavy Interleukin-based therapies that are both very expensive and hard to bear for the patient.

Patients with radioresistant clinically localized prostate cancer may be treated by various means. Although androgen ablation is relatively noninvasive, it cannot be considered a curative option. We believe that a subset of patients with locally recurrent prostate cancer without subclinical metastatic disease exists and would benefit from maximally aggressive local therapy. Salvage surgery may offer long-term cancer control, particularly when the tumor is organ-confined, but is a technically challenging operation with a high incidence of postoperative incontinence. Cryoablation of the prostate for postirradiation recurrence may offer a less invasive alternative to radical surgery, but its long-term efficacy remains to be fully determined. Each therapeutic option has its characteristic attendant morbidity and the choice of therapy for local recurrence should be made with informed consent after frank discussion between physician and patient. We propose the treatment algorithm shown in Figure 1 for the management of patients with suspected recurrence after radiation therapy with the caveat that individual therapeutic strategies must be patterned around individual patient needs.

Seromuscular spiral cuff perineal colostomy may be an alternative to abdominal wall colostomy after abdomino-perineal excision. We present our initial experience with the procedure in 13 patients operated upon between March 1993 and December 1997. Patients undergoing abdomino-perineal excision for rectal cancer, under 65 years of age, without severe concomitant disease, and strongly motivated to comply with an intensive postoperative physiotherapy were selected. The neosphincter procedure comprised a pull-through of a sufficient length of well-vascularized colon, 12 cm of which was then cleared of fat. In this segment, the seromuscular layer was separated from the mucosa, cut into a longitudinal sheet and wrapped in spirals around the colon at its perineal insertion. One patient died from pulmonary embolism. A second patient suffered from ischemic necrosis of the distal colon and lost his neosphincter. Minor complications included one stenosis, corrected by surgery, and one iatrogenic lesion on rectoscopy at another institution. No patients experienced local recurrence, while four patients presented distant metastases. Initially, all patients suffered from incontinence. After 6 months, 6 of 11 evaluable patients showed total and 5 showed partial continence.

Transanal endoscopic microsurgery (TEM) allows minimally invasive full-thickness local excision of rectal tumors with perirectal fat dissection. Thirty-seven patients with extraperitoneal rectal carcinoma underwent full thickness TEM resection for T1 (10 patients), T2 (20 patients), and T3 (6 patients) lesions, with associated radiotherapy in the second and third group. One patient, staged as T2, underwent full-dose radiotherapy and TEM and the pathologist did not find cancer cells on the specimen (pT0). Morbidity included would dehiscence and stool incontinence in three and two patients, respectively, that resolved with medical therapy and rectovaginal fistula in one patient that required reoperation. No perioperative mortality was observed. Mean follow-up was 35 months (range 17-60 months), with two local recurrences (5.4%) that were successfully retreated. Cancer-related mortality due to systemic metastases was 8.1%. This is the first clinical study reporting on the application of TEM combined with radiotherapy for the treatment of T2 and T3 rectal cancer in selected patients. This approach is feasible, safe, and appears to be effective at the present duration of follow-up, with preservation of normal and sphincter function.

Patients with localized adenocarcinoma of the prostate gland (CaP) are frequently (approximately 50%) found at radical prostatectomy to have extracapsular disease or positive surgical margins. The management of these patients is a subject of controversy because some question the impact of this manifestation of CaP on patient survival or disease-free survival. Between 1976 and 1991, 241 patients with pathologic stage C (T3N0) were treated in this medical center. Of these 241 patients, 201 (83%) received a planned postoperative pelvic irradiation consisting of 48 Gy given to the prostatic fossa, whereas 40 (17%) patients were treated with radical prostatectomy alone. The two study urologists selected these patients not to receive postoperative irradiation based on intraoperative findings and important prognostic factors. Comparison of treatment outcomes in these two treatment groups is a subject of this report. The 201 patients treated with surgery-radiotherapy (S+RT) combination had a higher pathologic stage, greater incidence of seminal vesicle involvement, p = 0.002, and higher mean and median preoperative prostate-specific antigen level, p < 0.0001, than the 40 surgery (S) alone patients. There was no significant difference in the incidence of higher Gleason's score by the treatment group, p = 0.14. In univariate analysis, there was no significant difference in survival, disease-free survival, and time to failure between the two treatment groups. In multivariate analysis after controlling for pathologic stage and Gleason's score, the 201 adjuvant radiotherapy patients were predicted to have recurrence at 68% (95% confidence interval 39%-118%) the rate of the 40 surgery-alone patients. Local recurrence with or without metastatic disease was found in 10% of surgery-alone patients as compared to 5% in those also receiving postoperative irradiation. Treatment tolerance was very good with minor radiotherapy complications only. There was no significant difference in the incidence of incontinence between the two treatment arms. In summary: (a) The use of moderate-dose postoperative radiotherapy was of low toxicity and it did not increase the incidence of incontinence. (b) Local recurrence was 5% in S+RT and 10% in S-alone patients. (c) In multivariate analysis, S+RT patients had 68% rate of recurrence of S-alone patients. (d) Adjuvant RT probably reduces the risk of recurrence in patients with poor prognostic factors. (e) These data need to be interpreted with caution because of the nonrandomized nature of the study.

Prostate adenocarcinoma is the most common nonskin malignancy in males and the second most common cause of cancer death in the United States (Landis et al., 1998). Initial treatments of surgery or radiotherapy may cause impotence and/or incontinence from neural damage (Eastham and Scardino, 1998; Porter et al., 1998). When extraprostatic or metastatic disease develops, castration or pharmaceutical androgen ablation is utilized (Catalona, 1994). Androgen-resistant recurrence indicates a poor prognosis and justifies experimental chemotherapy (Oh and Kantoff, 1998). G207 (Mineta et al., 1995; Yazaki et al., 1995) is a multimutated herpes simplex virus 1 (HSV) vector that replicates within cancer cells, causing cellular death; however, replication is limited in normal cells, including those of the nervous system. In vitro, G207 at a low multiplicity of infection (MOI of 0.01) is oncolytic for multiple human prostate cancer cells. In athymic mice, a single intraneoplastic inoculation of G207 completely eradicates >22% of established subcutaneous human prostate cancer tumors irrespective of hormonal responsiveness. Two intraneoplastic inoculations of G207 completely eradicated two of three recurrent previously irradiated tumors and two intravenous administration of G207 induced tumor regression in distant subcutaneous tumors and completely eradicated one-fourth of the tumors.
