Among 400 observations by the authors, 2 per cent were admitted without and another 22 per cent with slight neurological disturbances. An incomplete transverse lesion of the cord with paraplegia was found in 61.7 per cent, a complete paralysis in 14.3 per cent of the cases. Meningiomas and neurinomas were found in 60 per cent of the patients. The average age of the tumour patients was 43,8 years. Meningiomas and metastases show a tendency to occur in older age groups. The "Glioma Age" was around 25 years. The majority of the tumours were located at the level of the thoracic cord. When breaking down according to the kinds of tumours, a different picture is obtained: neurinomas are chiefly located in the region of the cervical medulla and the thoracolumbar region; gliomas are mainly found in the cervical part of the medulla up to the central thoracic cord. A dissociation of the cerebrospinal fluid was found in 90 per cent of the examinations; in 50 per cent of the patients it was above 200 mg%. Within a period of four weeks after the operation, the following results were obtained: 5 per cent free from complaints, improvement in 39 per cent, aggravation in 10 per cent and 46 per cent still uninfluenced. Meningiomas and neurinomas showed the highest degree of improvement. 24 per cent of the patients suffered from transitory rectovesical disturbances, 15 per cent from urinary tract infections, 12 per cent from decubitus, 9 per cent from wound healing disturbances and another 9 per cent from pneumonia. Meningitis was found in 2 per cent. Within four weeks post operationem, the death rate was 10.5 per cent, but this was in the phase before the introduction of microsurgery. On the accuracy of the diagnoses: in 18 per cent the neurological findings were in agreement with the diagnosis and in 49 per cent they showed differences of 1 to 3 segments; in 11 per cent no definite diagnosis could be made. In 46 per cent the native X-ray picture showed pathological changes. Myelography with positive contrast media showed positive findings in 97 per cent and 98 per cent of positive findings were obtained with myeloscintigraphy.

Forty-one patients with adenocarcinoma of the prostate localized in the pelvis (stage A2, NX; 3, A2, pN0; 5, B, NX; 5, B, pN0; 1, C, NX; 13, C, pN0; 7, C, pN1; 7) underwent curative external radiotherapy. Thirty-two cases were treated by fast neutron combined with or without Liniac X-ray and 9 cases were treated by Liniac X-ray. Twenty-six cases were well controlled by radiotherapy, but 15 cases recurred and were followed by endocrine therapy. The types of recurrence were local growth in 3, distant metastases in 11, and both in 1. These recurrences occurred in the cases of large prostatic carcinoma, small radiation field in NX cases or low radiation dose. The five-year disease-free survival rates of stage A2, B, C were 86, 66, and 47%, respectively and the five-year overall survival rates were 100, 100, and 53%, respectively. The cases with well differentiated carcinoma had better prognosis than those with poorly differentiated carcinoma (p less than 0.05). As 58% of the cases which were given concomitant endocrine therapy were controlled for over 2 years, endocrine therapy seems to be effective in the cases of failure after radiotherapy. Most of the complications were slight and only one case with complication of sacral decubitus needed surgical treatment. It was concluded that external radiotherapy was a good modality for prostatic carcinoma localized in the pelvis.

Six patients underwent translumbar amputation (TLA), a life-saving procedure, after standard modalities of therapy failed to control the progression of the disease. The primary diagnoses were as follows: pelvic arterial-venous (A-V) malformation, 1; sacral chordoma, 3; giant cell tumor of the sacrum, 1; and paraplegia with squamous cell cancer arising in intractable decubitus, 1. There were no operative deaths. The following postoperative complications developed in five patients: urinary fistulae, 2; small bowel obstruction, 1; intraabdominal bleeding, 1; hypertension, 2; small bowel fistula, 1; and dehiscence of skin closure, 1. Two patients died with distant metastases (24 months) and distant metastases with local recurrence (6 months). The remaining four patients were alive and well 72, 56, 48, and 18 months after the surgical procedure. All of these patients have reached the rehabilitation goals.

We invented a new surgical approach to the kidney through the flank to perform a radical nephrectomy for renal cell carcinoma. With the patient in usual lateral decubitus position keeping the dorsum vertical to the operating table, a skin incision is made over the XII rib from the posterior axillary line to the lateral edge of the rectus muscle. After the tip of XII rib is resected by about 5 cm, the retroperitoneal space is entered. Blunt dissection of the posterior aspect of Gerota's fascia from fasciae of the quadratus lumborum and psoas muscle is easily carried out with a liver retractor or intestinal spatula. The pulsating renal artery can be identified through Gerota's fascia when the renal hilus is exposed. Following ligation and division of the artery, renal vein is exposed. On the left side, adrenal, gonadal and occasionally lumbar veins are also ligated and severed in addition to the renal vein. Then, the kidney in Gerota's fascia is removed en bloc with perinephric adipose tissue and adrenal gland. Of 21 patients with renal cell carcinoma seen during 1 year and 3 months from June 1987, 11 underwent this operation, and other 10 patients transperitoneal radical nephrectomy because of the possible tumor extension into the renal vein, inferior vena cava or adjacent organ, the severe spinal deformity or metastases and the necessity of additional surgical procedures for concomitant benign intraperitoneal diseases. The blood loss was smaller and operating time was shorter significantly in the translumbar group than the evaluable transperitoneal group. None of those in the translumbar group received blood transfusion. As complications, pneumothorax due to pleural injury during operation and postoperative incisional hernia occurred each in one patient, but no other serious one was found. From the above results, this approach seems to be one of choices for the surgical treatment of renal cell carcinoma, as long as the tumor is not likely to extend to adjacent organs, ipsilateral nodes or the inferior vena cava.

Genital tumors represent a special group requiring effective and curative treatment while functional and cosmetic demands require tissue sparing techniques. For these reasons, micrographic surgery is indicated. Over the past 5 years we have treated 24 such patients utilizing standard techniques for micrographic surgery. The patient population included twenty male and four female patients with ages ranging from 27 to 80 years. Histologically confirmed diagnoses included squamous cell carcinoma, Bowen's disease, verrucous carcinoma, basal cell carcinoma, Paget's disease, and leiomyosarcoma. These were located on the penis, scrotum, perineum, and buttocks. Seven of these patients were considered to have recurrent tumors. Preexisting conditions existed in 6 patients, including balantis xerotica obliterans, trauma, decubitus ulcer, and hidradenitis suppurativa. All surgery was performed under local anesthesia in the cutaneous surgery unit. Average pretreatment tumor size was 2.0 X 1.9 cm. Average postoperative defect size was 4.5 X 3.7 cm. Tumors were excised with an average of three stages and 18 sections. Most defects (65%) were allowed to heal by secondary intention, five (21%) were closed primarily, and three were referred for closure. After surgery five patients developed metastases in their regional lymphatic system. No patients developed local recurrence. Micrographic surgery is a most useful treatment modality in patients with genital tumors for control of local disease. However, patients with squamous cell carcinoma should be considered for elective regional lymph node biopsy and/or dissection in conjunction with micrographically controlled excision of the primary tumor.

The development of squamous cell carcinoma in pressure sores is a rare event, considering the high incidence of pressure sores within the elderly and paraplegic populations. The clinical courses of 10 patients with pressure sore carcinoma have been reviewed. The presence of a velvety, cauliflower-like growth on the surface of a long-standing pressure sore should alert the surgeon to the possibility of malignant degeneration. Most of these tumors are well-differentiated squamous cell carcinomas. Of the 10 patients, 8 (80%) died from massive local recurrence or distant metastases an average of 17 months after resection and flap closure despite having apparently localized disease. One patient was disease free when lost to follow-up at 2 years, and 1 patient is without evidence of recurrence or metastases 3 months postoperatively. Altered immunocompetence may play a role in the rapid progression and high mortality associated with this tumor after surgical manipulation.

Percutaneous vertebroplasty is a technique of interventional radiology, which allows to fulfill pathologic vertebral body with acrylic cement. This method is used to strengthen the vertebral body and reduce pain in some diseases involving the vertebra. Main indications are spine angiomas, metastases and osteoporosis. The vertebroplasty is realised under neuroleptanalgesia for cervical spine antero lateral way is used. For thoracic or lumbar vertebra, the way of approach is usually transpedicular; but in some cases, this approach is not possible: osteolysis of the pedicle, surgical osteosynthesis; in such cases, a postero lateral approach is realized. Technical incidents are not rare, but are usually asymptomatic. More frequent are venous filling with cement; the veins involved can be intra spinal (vertebral plexus) or paraspinal. Instead of this frequency pulmonary embolism in direct relation with the vertebroplasty where not reported. Extravasation in intervertebral disk or soft tissue can also be observed. This last incident can be in relation with the way of the needle or with a cortical rupture. Local complications are rare: rate of neurological deficit or infection is under 0.5%. Radicular pain is observed in 3.7% of cases. These complications are in close relation with the radiological involvement of the vertebra: cortical disruption, heterogeneous Lysis of the vertebral body. The frequency of complications is 1.3% in osteoporosis, 2.5% in spine angiomas and 10% in metastatic disease. Indications concern lesion involving the vertebral body: symptomatic spine angiomas; painful osteoporotic fractures after medical treatment or in patients with a high risk of decubitus complications; in metastatic disease, vertebroplasty is a way to consolidate the vertebral body and release pain. It can be usefull in recurrent pain after chemotherapy and/or radiotherapy, and also in unstable vertebra to obtain a stabilization before radiotherapic or chemotherapic treatment isolated or in combination with surgical osteosynthesis.

Marjolin ulcers are malignant tumors arising in chronic wounds. Strictly defined, they include carcinomas that transform from the chronic open wounds of pressure sores or burn scars. They behave aggressively and have a propensity for local recurrence and lymph node metastases. A retrospective study was done at a single institution identifying six individuals who had chronic wound ulcers that underwent malignant transformation into a carcinoma. Sinus tract degeneration in osteomyelitis was not included. The average latency time between ulcer formation and documentation of a malignancy was 30 years. All wounds were about the pelvis or flank. Major oncologic surgical procedures were done in an attempt to eradicate the cancer. High-grade tumors had positive lymph node metastases, portending a grave prognosis. All four individuals with nodal metastases eventually died of systemic disease. Early recognition and proper staging offers the best chance for cure.

Case 1. A 58-year-old man underwent radical nephrectomy due to a tumor in the left kidney (renal cell carcinoma, clear cell subtype, G3, pT1bpN0) in 1988. Thirteen years later, he underwent surgical resection of metastases to lung and cerebrum and gamma ray knife resection of two other sites of metastases to cerebrum in 2001. He had no evidence of disease in April, 2003. Case 2. A 53-year-old man underwent radical nephrectomy due to a tumor in the right kidney (renal cell carcinoma, clear cell type, pT1apN0) in 1987. From 1996 to 2001, irradiation therapy to multiple metastases to thoracic vertebrae (50 Gy), rib (50 Gy), para-aorta lymph nodes (40 Gy), sacrum (44 Gy) and sternum (44 Gy), and surgical resection of dermal metastasis were performed. Paraplegia occurred due to regrowth of thoracic bone metastasis in December, 2001. In February, 2002, he died of septic shock caused by infection of decubitus. Surgical resection and palliative therapy of recurrent metastatic foci was useful to improve the quality of life and probably prognosis.

The use of self-expandable metallic stents in colorectal stenoses, both benign and malignant, is a recently born treatment, quickly widespread because of its simplicity and therapeutic efficacy. It is particulary useful, like emergency temporany treatment, in malignant colonic obstruction; in these cases the temporary endoprosthesis positioning allows the intestinal transit and to overcame the emergengy phase. After patient conditions improvement, he can be operated and the endoprosthesis removed within operating specimen. In some particularly serious cases, when only a derivative intervention is mandatory because of the general conditions of the patient or the advanced stadium of the illness, stenting can also represent definitive palliative treatment. In fact, it allows contemporary resolution of the occlusion and of the physiopathologic alterations, with hospital cost reduction and a quality life imprevement for the patient thanks to the colestomy absence. In benign pathologies, self-expandable stents are used for a long time in the superior gastrointestinal and biliary tract; now stents have found employment also for the treatment of the post-operative fistula, intestinal diverticular occlusion and for the treatment of post-anastomotic or radiotherapy strictures. The Authors report two cases observed in emergency with complication determinated by positioning of colonic endoprosthesis for previous occlusive episode. The first case, a 56 year-old woman with a decubitus perforation occurred by stent, previously positioned with only palliative intent for a sigma-rectal metastatic cancer: in the second case, a 75 year-old man, the endoprosthesis had been positioned for a postoperative benign stricture of colorectal anastomosis for neoplasm: in this case the stent had determined a vescico-rectal fistula and after a new intestinal occlusion.
