The clinical and diagnostic significance of abdominal computed tomography (CT) was evaluated in 123 patients with primary gastric adenocarcinoma and disseminated peritoneal metastases. The peritoneal metastases were diagnosed by CT findings such as ascites (30.1%), wall thickness of the intestine (1.6%), increase in fat density of peritoneal fat tissue (4.9%), peritoneal nodules (2.4%), and hydronephrosis (4.9%). The overall diagnosis of peritoneal metastasis was 37.4%. The CT findings of peritoneal metastases were significantly correlated with anemia, poor performance status, distant metastases, P3, and resectability of the primary tumor. The survival of the patients with positive findings was significantly poor (150 days of median survival), compared with those without findings (230 days). The abdominal CT thus provides information for diagnosis of peritoneal metastases and on the prognosis in patients with primary gastric cancer.

Inflammatory myofibroblastic tumor is a rare entity composed of spindle cells admixed with variable amounts of extracellular collagen, lymphocytes, and plasma cells. In the genitourinary tract, inflammatory myofibroblastic tumor most commonly occurs in the bladder. Isolated case studies of inflammatory myofibroblastic tumor of the kidney, renal pelvis, and ureter have been previously reported. Our series includes 12 cases of inflammatory myofibroblastic tumor occurring in the renal pelvis (six cases), renal parenchyma (four cases), and immediate perirenal soft tissue (two cases). Clinical presentation included flank pain (two patients), painless gross hematuria (one patient), and ureteropelvic junction stenosis with hydronephrosis (one patient). The remaining eight patients were asymptomatic. All patients underwent nephrectomy. The tumors were characterized by firm white tissue or had a myxoid "gelatinous" appearance. Three histologic patterns were identified in the tumors, including a myxoid vascular pattern, a compact spindle cell pattern, and a hypocellular fibrous pattern. Immunohistochemical and electron microscopic studies supported a myofibroblastic proliferation. All cases were negative for anaplastic lymphoma kinase. Follow-up was available in eight cases and ranged from 1 to 17 years with no evidence of recurrence. Based on this series, renal inflammatory myofibroblastic tumor is a proliferative lesion of myofibroblasts of uncertain pathogenesis with no identified potential for recurrence or metastases.

We describe a patient with adenocarcinoma of the lung who developed hydronephrosis secondary to compression by right common iliac lymph node metastases. The most common primary sites of cancers causing ureteral obstruction are the cervix, prostate, bladder and colo-rectum. To date, few reports of ureteral obstruction attributable to lung cancer have been published. Although rare, physicians should be aware that hydronephrosis can complicate the course of patients with non-small cell lung cancer.

We report a case of signet-ring cell carcinoma of the urinary bladder. A 48-year-old female was hospitalized because of general fatigue, pollakiuria and residual sensation. Renal ultrasonography disclosed bilateral hydronephrosis. The serum level of cretinine was 3.1 mg/dl, and we diagnosed the patient with post-renal failure. Cystoscopic examinations revealed non-papillary sessile tumors in the trigone. Histopathological findings of the biopsy specimen demonstrated signet-ring cell carcinoma. There was no evidence indicating bladder metastasis from the cancer in other organs. The patient died of cachexia 5 months after the diagnosis. She was autopsied, and the diagnosis of signet-ring cell carcinoma of the urinary bladder with metastases in various organs was confirmed. This disease is extremely rare and has a poor prognosis. We review the previous cases reported in the literature.

Acute pains requiring emergency management in oncology can be considered as physiopathological, somatic or visceral nociceptive pains. They are linked: to the tumour, indicating a modification of the tumoural evolution (necrosis, haemorrhage, fracture, acute obstruction of hollow organs or canals, occlusion, hydronephrosis); to the treatment: (inflammation of mucosal membranes, anusitis, post PL syndromes); and to invasive investigations. They are equally neuropathic, revealing an underlying threatened or confirmed medullary compression, or induced by neurotoxic chemotherapy. They are also analysed according to their mode of apparition: mechanical, arising as acute on chronic pain (the pre-fracture pain of metastases); insufficiency of the duration of therapeutic efficacity; an acute episode of neuropathic pain that is often lancing, unpredictable and inevitable. In all cases, it needs to be quantitatively and qualitatively analysed: evaluation, flavour of the symptoms; in order to choose one or a combination of adapted molecules, true antalgics or co-antalgics, antidepressants and anticonvulsants. To counteract this pain, medications with a short onset of action and a short half-life should be used to avoid side effects. These are administered in an intercurrent manner, initially starting at a low dose, modified daily according to the utilisation of supplementary doses. It is necessary to anticipate pain provoked by physical examinations or nursing care as much in the timing as the pharmacology, in using antalgics and/or anxiolytics with a short duration of action. Acutely emerging pains, whatever be their type, arising in the context of cancer and long-term pain are sensitising elements to all further pains, as they imprint in the memory, and are very negatively conditioned by the anguishing context of the illness.

The case records of patients who had nephrectomy from 1989 to 1998 were retrieved. Data extracted for analysis included age, sex, clinical features, indications for nephrectomy, post-operative complications and histological findings. Thirty-four unilateral nephrectomies in 21 males and 13 females were done. The patients were aged between 1.5 to 75 years. The predominant presenting features were abdominal pain (76.5%), abdominal mass (70.6%), haematuria (61.8%) and weight loss (47.1%). Diagnostic investigations were intravenous urography and renal ultrasound scan. The major indications for renal exploration included non-functioning kidney and renal mass suspected to be carcinoma. The histopathological findings included renal malignancy 23 (67.6%), hydronephrosis 6 (17.6%) and renal infections 3 (8.8%). The male/female ratio in nephrectomy for malignancy was 1:1.09. Renal trauma was the indication in only one patient. Non-functioning kidneys on intravenous urography (IVU) occurred in both malignant and infective lesions. Hypertension was found in 9 patients preoperatively. It resolved in 7 patients after operation. The histological finding in one kidney differed from what was assumed at operation. Follow-up USS showed compensatory hypertrophy in the remaining kidneys. Post-operative sepsis occurred in 4 patients. One of these was a retroperitoneal abscess. Two patients with huge tumours died on the operating table. Two died from sepsis. Four patients died from metastatic disease within two years after operation. Malignancies constituted the commonest indication for and commonest cause of mortality in nephrectomy. Antibiotics prophylaxis is advocated. All nephrectomy specimens should be subjected to histopathological examination.

The occurrence of cutaneous metastatic disease from colorectal cancer is uncommon and typically signifies widespread disease with poor prognosis. Colorectal metastases usually occur within the first 3 years of follow up, and the median survival of patients after the appearance of cutaneous metastatic lesions is 18 to 20 months. We describe an unusual case of a 60-year-old woman with a metachronous skin lesion as the sole site of metastatic disease, and a relatively long interval between the appearance of skin metastases and death. The woman was found to have an adenocarcinoma of the rectum, a Dukes' C lesion, extending over the entire rectal wall into the perirectal fat; five of eight regional lymph nodes showed metastases. Adjuvant radiotherapy followed by chemotherapy was administered for about 1 year. A subcutaneous lump on the left abdominal wall found 16 months postoperatively was metastatic of rectal origin. A metastatic adenocarcinoma of rectal origin was found in a single left lower axillary node 26 months later. Despite metastatic work-up for the next 2 years, an enlarged and palpated metastatic left inguinal lymph node appeared and was subjected to radiation. Computerized tomography (CT) examination 5 years after the first presentation of the rectal tumor and almost 4 years after the diagnosis of abdominal skin metastases disclosed recurrent pelvic disease with severe left hydronephrosis. Treatment by systemic chemotherapy was partially successful, but she died 8 months after this chemotherapy was initiated.

Primary small cell carcinoma of the ureter is very rare. We report a case associated with SIADH (syndrome of inappropriate secretion of ADH) -like symptoms. A 53-year-old man presented to our hospital with lower back and left lower quadrant abdominal pain. Computed tomography revealed left hydronephrosis, a peri-ureteral left lower quadrant mass, and retroperitoneal (RP) lymphadenopathy. Transduodendal biopsy of a RP lymph node revealed small cell carcinoma. He was referred to urology for further evaluation. Urography showed an obstructing mass invading the left ureter. Comprehensive metastatic evaluation revealed no other lesions. Thus, we diagnosed primary small cell carcinoma of the ureter with RP lymph node metastases. In addition, he developed SIADH-like symptoms, and we strongly suspected that it was due to ectopic production of ADH from this carcinoma. He was treated with systemic chemotherapy (methotrexate, epirubicin, and cisplatin). Following this, we performed radical nephroureterectomy with RP lymph node resection. However, he died of recurrent disease five months later.

We report a case of port site metastasis of primary adenocarcinoma of the renal pelvis after a laparoscopic nephrectomy. A 76-year-old woman was admitted to our hospital with a complaint of anorexia, general malaise and left abdominal distension. Computed tomography revealed severe hydronephrosis in the left kidney. Laboratory examination revealed a high serum level of CA19-9 (155 U/ml). However, antegrade and retrograde pyelography revealed no filling defects and urine cytopathology for renal pelvis showed no malignancy. Thus, on the suspicion of a ureteropelvic junction stenosis, a laparoscopic nephrectomy was performed. There were some papillary tumors in the renal pelvis and a histopathological examination of the tumor revealed a papillary adenocarcinoma. Twelve months after nephrectomy, left iliopsoas muscle metastasis was found. Thus irradiation therapy with a total of 30 Gy was performed. However, 3 months later, the patient developed metastasis at the trocar site and the serum level of CA19-9 elevated to 6,720 U/ml. She died of multiple metastases from adenocarcinoma of the renal pelvis 4 months after port site metastasis.

A 43-year-old woman who complained of abdominal fullness, appetite loss, and constipation was diagnosed as unresectable advanced schirrhous gastric cancer with left supra-clavicular lymph node metastases, massive ascites, rectal stenosis, and bilateral hydronephrosis due to peritoneal metastases. The biopsy specimen showed a poorly differentiated adenocarcinoma with signet-ring cells. After placement of the bilateral ureteral stents, she was treated with combined chemotherapy of biweekly paclitaxel (120 mg/m2, day 1, day 15) and TS-1 (80 mg/day, days 1-14 with 2-weeks rest). Subjective symptoms were relieved after one course of the chemotherapy. After 3 courses, computed tomography showed markedly reduced supra-clavicular lymph node metastases and no ascites. Radiographic and endoscopic examinations also demonstrated remarkable improvements in compliance of the gastric and rectal walls. These findings suggested that partial response on Response Evaluation Criteria in Solid Tumors (RECIST) was obtained. After the first course, the treatment was continued on an outpatient basis. There were no adverse effects over grade 2 throughout six courses of the chemotherapy. The biweekly paclitaxel and TS-1 chemotherapy may well be an effective treatment for advanced schirrhous gastric cancer with carcinomatous peritonitis.
