Induced hypertensive chemotherapy with angiotensin-II for liver metastases from gastric cancer

The theoretical purpose of induced hypertensive chemotherapy used together with injection of Angiotensin-II is to increase the delivery of anticancer drug to the target tumor tissue by increasing blood flow in the tumor. Angiotensin-II (0.1 mg) was dissolved in 50 ml of normal saline, and given through a peripheral vein by a microinfusion pump. When systolic pressure rose to about 140 to 150 mmHg, Mitomycin C (10 to 20 mg/body) was given for 10 minutes via implanted port, whose tip was located in hepatic artery, followed by continuous infusion of 5-FU at 250 mg/day for 5 days. Response could be measured in 4 of all cases (66.7%). CR was found in 2 and PR in 2. Bone metastases or systemic lymph node metastases occurred after a few months in one CR case and one NC case. We concluded that this mode of chemotherapy was a useful measure for the treatment of liver metastases from gastric cancer.     

Multimodality treatment for gastric carcinoid tumor with liver metastases

Carcinoid tumors are the most common neuroendocrine tumors in the gastrointestinal tract, and between 10% and 30% of these tumors are gastric in origin. Three types of gastric carcinoid tumors are recognized: type I, associated with chronic atrophic gastritis type A; type II, associated with multiple endocrine neoplasia; and type III, sporadic and the most malignant. We present a patient with an aggressive, sporadic-type gastric carcinoid that metastasized to the liver. Her symptomatic treatment included the somatostatin analog octreotide. Octreotide scintigraphy demonstrated that this tumor avidly bound the peptide. The patient's gastric carcinoid (assessed by endoscopy and endoscopic ultrasound) regressed and she underwent hepatic artery embolization for her liver metastases. After initial partial CT resolution the tumor grew, compressing the inferior vena cava. The patient underwent orthotopic liver transplant with excellent recovery, although she was subsequently found to have two small lung metastases. She has responded well to adjuvant Indium-111 octreotide receptor targeted therapy. This case highlights the therapeutic options for metastatic neuroendocrine tumors, including liver transplantation and adjuvant receptor targeted therapy.     

Results of resection of gastric cancer with distant metastases

BACKGROUND/AIMS: The present study was carried out in order to examine the outcome of resection in cases of gastric cancer with distant metastases. METHODOLOGY: The survival rates of two hundred and eighty-one patients who had undergone resection for primary carcinomas of the stomach, and who had distant metastases according to the TNM classification, were studied. RESULTS: The 5-year survival rates for patients with metastasis to the peritoneum or group 3 nodes were 8.9% and 15.3% respectively and were significantly higher than the survival rates for patients with metastasis to the liver (0%), to group 4 nodes (2.2%) or to more than one site among the liver, lymph nodes and peritoneum (3.5%). Moreover, the 5-year survival rates for patients with metastasis to the peritoneum and N3 nodes increased significantly to 29.4% and 24.2%, respectively, when curative surgery was performed. CONCLUSIONS: The findings of the present study suggests that metastases to the adjacent peritoneum or group 3 nodes have a greater chance of being cured using radical surgery, and that gastrectomy with extended lymphadenectomy (D2-D3) may be used for advanced gastric cancer if there is no gross evidence of metastasis to the distant peritoneum, liver or group 4 nodes.     

Residents' management of the symptoms associated with terminal cancer

The principal aim of palliative care is to bring symptomatic relief to patients with progressive disease. Residents graduating from a university general surgery training program should be competent to manage common symptoms associated with advanced cancer. This study used performance-based testing to evaluate the skills of resident physicians in managing common symptoms of a patient with advanced cancer. Thirty-three resident physicians (PGY 1 to 6) were presented with four clinical symptoms of a patient with advanced cancer: (1) nausea and vomiting associated with regular morphine use; (2) lack of appetite in the last weeks of life of a terminally ill patient; (3) constipation associated with codeine analgesia; and (4) dyspnea associated with diffuse lung metastases. The management plan for the symptom problems was evaluated by using a predefined checklist. A significant number of residents showed deficits in the management of common symptoms of advanced cancer. Scheduled dosing of antiemetics was infrequently prescribed for opioid-related nausea and vomiting. Most physicians inappropriately managed lack of appetite by using forced feeding. Opioids were infrequently used in the management of terminal dyspnea. The absence of difference in scores between junior and senior residents suggests that adequate management of the symptoms of terminal cancer is not being effectively taught in postgraduate training programs.     

A case of membranous glomerulonephritis associated with gastric cancer

We describe a patient with gastric cancer and membranous glomerulonephritis (MGN). The patient, a 61-year-old male, was admitted to our Hospital in May, 1996, because of proteinuria and hyperlipidemia persisting for a year. Laboratory examination filled the criteria of nephrotic syndrome and renal biopsy revealed MGN of stage II. Prednisolone therapy (40 mg/day p.o.) was started, followed by a gradual decrease in proteinuria from 4.5 g/day to 0.1 g/day. Endoscopic examination was performed because of stomach-ache revealed advanced gastric cancer of Borrmann 4. Desiring for a conservative therapy, he was discharged and moved to a hospice. In literature review, MGN is the most frequent lesion among various glomerular diseases associated with malignancy, such as the lung, stomach, and colon, particularly at an elderly ages, and sometimes antedates the detection of malignancy, as in the present case. In several cases with MGN, immune-complexes composed of tumor antigens, such as carcino-embryonic antigen, and antibodies have been reported to deposit in basement membrane of glomeruli, causing MGN. In the renal and gastric cancer tissues of the present case, the presence of three novel tumor-associated antigens, Span-1, Thomsen-Friedenreich antigen (T antigen) and F1 alpha antigen, was examined, using a immuno-peroxidase method. Although none of these three antigens were immuno-stained in the renal tissue, clinical course and literature review suggest that MGN in this patient seems to be associated with gastric cancer, which may have produced MGN-causing tumor antigens other than the three antigens. It should be emphasized that malignancy should be carefully and routinely examined in patients with MGN, particularly at elderly ages.     

Long-term complete response in two cases of liver metastases from rectal and gastric cancer treated with intra-arterial infusion chemotherapy of leucovorin and 5-fluorouracil

Intra-arterial infusion chemotherapy combined with leucovorin (LV) and 5-fluorouracil (5-FU) was performed in two patients with multiple metastases from rectal and gastric cancer. In each patient LV 45 mg was infused as a bolus just before and after 5-FU 1,000 mg/4 hrs administration. Thereafter 5-FU dose was decreased gradually. This regimen was principally repeated weekly on an outpatient basis. In both patients PR was detectable 3 and 4 months after the beginning of chemotherapy, and CR was obtained in 21 and 6 months, respectively. Neither patient showed any signs of recurrence and are in good health 35 and 30 months after initiation of chemotherapy. These findings suggest that our protocol has an excellent anti-tumor effect and improves the QOL in some patients for a long time.     

Hand symptoms and pregnancy

The purpose of the present study was to identify the incidence of hand symptoms related to pregnancy in a Danish population. Three hundred and thirty-five consecutive postpartum patients were interviewed by questionnaire. Hand symptoms had been noted by 16%, among these 30% described a classic median-nerve symptom distribution (carpal tunnel syndrome) and 24% of patients described an ulnar nerve distribution. Most symptoms were bilateral, commenced in the third trimester and resolved soon after delivery. There was a significant correlation of hand symptoms in pregnancy with the presence of swelling and a significant correlation to parity (first). Hand function and sleep had been disturbed in half of the patients. Half of the patients had mentioned their symptoms to their doctor and one had been sent to treatment. Hand symptoms during pregnancy are common, and their severity is often underestimated. Symptoms of the carpal tunnel syndrome are easily relieved by a night splint.     

A case of prostatic ductal adenocarcinoma with endometrioid features, associated with rectal invasion and multiple liver metastases

A 66-year-old man was admitted with destructive arthropathy, and calcium pyrophosphate dihydrate was demonstrated in the synovial fluid specimen. He was found to have a hyponatremia. The serum sodium concentration was 121 mmol/l, plasma arginine vasopressin (AVP) 6.6 pmol/l, and serum interleukin (IL)-6 96 pg/l. The clinical findings suggest the diagnosis of syndrome of inappropriate secretion of antidiuretic hormone (SIADH). However, destructive arthropathy with increased values of C-reactive protein and IL-6 is the only background of SIADH in this patient. We suggest the possibility that IL-6 produced at inflammatory lesions may have stimulated an excessive release of AVP resulting in the hyponatremia and hypochloremia of SIADH.     

Calcifying liver metastases in a case of primary lung cancer

A 50-year-old man presented with primary lung cancer with bone lesions and calcifying liver nodi. Two months after stopping chemotherapy, he died. Autopsy revealed multiple organ metastases. Histologically, the calcified nodi in the liver proved to be affected by tumor metastasis.     

Arterial infusion chemotherapy of 5-FU and leucovorin for patients with liver metastases from colorectal cancer

Fifteen patients with liver metastases from colorectal cancer were treated by arterial infusion of 5-FU and leucovorin. Two regimens were performed. One was weekly bolus infusion of leucovorin following bolus infusion of 5-FU (bolus group), the other was 5 days continuous infusion of 5-FU and leucovorin in 3 weeks (continuous group). One PR was obtained both in the bolus group and in the continuous groups. The objective response rate was 11% in the bolus group and 20% in the continuous group. The one- and 2-year survival rates for these patients were 40% and 0% in the bolus group, and 80% and 60% in the continuous group, respectively. These results suggest that continuous arterial infusion of 5-FU and leucovorin was more effective than individual bolus arterial infusion of leucovorin and 5-FU for patients with liver metastases from colorectal cancer.     

Carcinoma of the colon with mandible and liver metastases

The aortic rupture in the pulmonary parenchyma or the bronchi rarely results in an haemoptysis. It means in most of the cases the rupture of an aortica aneurysm. We relate the observation of a aorto-bronchial fistula from a tuberculosa origin in an old woman case. Although the tuberculosa aortitis is becoming very exceptional, it still remains the cause of aorta rupture, with the formation of a false aneurysm which is rapidly fatal and so, it is important to search for it before any capricious haemoptysis.     

Extended lymphadenectomy is associated with a survival benefit for node-negative gastric cancer

BACKGROUND: The activation of the zymogen plasminogen to the serine protease plasmin by urokinase-type (uPA) and tissue-type (tPA) plasminogen activators (PA) is an important event in a variety of physiologic and pathophysiologic processes in mammals. Enhanced PA activity occurs during angiogenesis and has been correlated in vitro and in vivo with increased tumor aggressiveness and is an indicator of poor prognosis in a variety of tumors in humans. Preliminary studies suggest that the antiulcer drug irsogladine maleate (IM) diminishes PA activity in vitro and may inhibit angiogenesis in vivo. To define the precise mechanism of angiogenesis inhibition by IM in vivo, we tested the ability of IM to blunt angiogenesis in a mouse cornea neovascularization model performed in wild-type and PA-knockout mice. METHODS: Three days prior to pellet implantation, groups of C57Bl/6 wild-type, uPA-deficient (upA-/-), and tPA-deficient (tPA-/-) mice received IM (300 mg/kg), IM (500 mg/kg), or vehicle (0.5% carboxymethylcellulose) via oral gavage. After 3 days of treatment, hydron polymer-coated pellets of sucrose aluminum sulfate containing 100 ng of basic fibroblast growth factor (bFGF) were inserted into surgically created pockets in the cornea of each mouse. On postoperative day 6, the neovascularization of each cornea was evaluated by a blinded observer using slit lamp microscopy and photographed. Angiogenesis was quantified by calculating vascular area (mm2) +/- SEM using a modified formula for a half ellipse that incorporates calibrated vessel measurements [Vessel length (mm) x Clock hours x pi x 0.2]. RESULTS: IM treatment (300 and 500 mg/kg/day) resulted in a dose-dependent reduction of angiogenesis in wild-type mice by 21 and 45.3% (P < 0.02, P < 0.001), in tPA-deficient mice by 42.6 and 46% (P < 0.001, P < 0.001), and in uPA-deficient mice by 27.2 and 46% (P < 0.05, p < 0.001), respectively. No quantitative differences in neovascularization were observed in either treatment group between transgenic mouse strains. No toxicity was noted in any group. CONCLUSION: IM inhibits bFGF-induced angiogenesis in wild-type, tPA-knockout, and uPA-knockout mice. The observation that IM significantly diminishes angiogenesis in both PA-deficient mice and wild-type mice suggests that the mechanism of action of IM may be independent of plasminogen activation.     

Complete omentectomy and extensive lymphadenectomy with gastrectomy improves the survival of gastric cancer patients with metastases in the adjacent peritoneum

BACKGROUND/AIMS: The omentum is the site where peritoneal metastases occur most frequently. It has not been shown whether complete resection of the omenta during gastrectomy improves the survival of gastric cancer patients with macroscopic peritoneal metastases. METHODOLOGY: We retrospectively analyzed 126 patients who underwent gastrectomies for gastric cancer with peritoneal metastases but without hematogenous metastases. The 126 patients were stratified according to their grade of peritoneal metastases into three groups: the P1 patients (patients with peritoneal metastases in the adjacent peritoneum but not in the distant peritoneum); the P2 patients (patients with a few peritoneal metastases in the distant peritoneum); and the P3 patients (patients with many metastases in the distant peritoneum). In each group, the survival and clinicopathological characteristics were compared between patients treated by complete resection of the greater omentum and the lesser omentum plus extensive lymphadenectomy during gastrectomy, versus patients treated by incomplete resection of the omenta and non-extensive lymphadenectomy during gastrectomy. RESULTS: Complete omentectomy and extensive lymphadenectomy during gastrectomy improved survival significantly only in the P1 patients. Other clinicopathological characteristics did not differ between them. CONCLUSION: Complete omentectomy and extensive lymphadenectomy is recommended in patients with peritoneal metastases in the adjacent peritoneum but not in the distant peritoneum.     

Uterine angiomyolipoma associated with pregnancy

Uterine angiomyolipomas are rare lesions composed of mature adipose tissue, smooth muscle, fibrous connective tissue, and blood vessels in varying proportions. We reported the first case of angiomyolipoma associated with a normal pregnancy. Initially, the tumor developed intramurally and could have been confused with a partial molar gestation. After delivery, tumor development was extensive and subserosal, making differential diagnosis from a sarcoma difficult. The question of histological diagnosis, as well as that of immunocytochemical analysis which seems to be helpful in such cases, is discussed here.     

Obsessional symptoms associated with risperidone treatment

OBJECTIVE: The aim of this paper is to report the occurrence of obsessional symptoms with risperidone treatment in a patient with no past history of obsessive-compulsive symptoms. CLINICAL PICTURE: A 26-year-old, single, Chinese lady with a chronic untreated schizophrenic illness was prescribed risperidone after she experienced side effects with other antipsychotic medication. After the second week on risperidone, she developed obsessional symptoms. TREATMENT AND OUTCOME: The obsessional symptoms responded to treatment with low dose clomipramine. CONCLUSION: The potential for the newer antipsychotic medication to precipitate or exacerbate obsessive-compulsive symptoms during treatment for schizophrenia must be borne in mind.     

Multivariate analysis of the prognostic factors of patients with unresectable synchronous liver metastases from colorectal cancer

PURPOSE: It frequently is observed that widely varying prognoses are given for patients with the same extent of liver metastases from colorectal cancer, even though the same treatment is performed on these patients. One of the reasons for this variance is that prognostic factors for these patients have not been defined. This study was designed to elucidate which clinicopathologic factors were the most important in the prognosis of 73 patients with unresectable synchronous liver metastasis from colorectal cancer. METHODS: Univariate and multivariate analysis of 11 clinicopathologic factors were performed using the Cox proportional hazard model. Survival curves were generated using the Kaplan-Meier method. RESULTS: Extent of liver metastases was the most significant variable in this survival analysis, although the extent of lymph node metastases of the primary lesion also was significant. However, the method of treatment was not a significant determinant in the survival for patients with unresectable liver metastases. Median survival of patients with H1, H2, and H3 was 13, 12, and 6 months, respectively, and there was a significant difference between survival curves for patients with H1 and patients with H3. Median survival of patients with n0, n1, and n2 was 13, 7, and 7 months respectively, and there was a significant difference between survival curves for patients with n0 and patients with n2. Median survival of 6 patients with H1 and n0 and of 17 patients with H3 and n2 was 28 and 4 months, respectively. There was a significant difference in survival curves between these two groups. CONCLUSION: Longevity of patients with unresectable synchronous liver metastases from colorectal cancer is affected adversely by the presence of nodal metastases and extent of liver metastases. This should be considered in the planning treatment.     

Cryotherapy of the resection edge after liver resection for colorectal cancer metastases

A 35-year-old female was referred to our clinic with a complaint of left flank pain in 1993. Drip infusion pyelography showed a filling defect of 25 x 24 mm in size in the left ureteropelvic junction. Computed tomography and ultrasonography revealed it as the renal stone. Percutaneous nephroureterolithotomy and extracorporeal shock-were lithotomy were performed. The stone was composed of 2,8-dihydroxyadenine (DHA). The patient was diagnosed as having a partial deficiency of adenine phosphoribosyltransferase (APRT) from the low APRT activity and a genotype of a compound heterozygote APRT*J/APRT*Q0 by T-cell analysis. The urinary excretion of 2,8-DHA crystals disappeared by the postoperative treatment with allopurinol. Cases of 2,8-DHA urolithiasis reported in the Japanese literature are discussed.
