Recent progress in elucidating the complex and heterogeneous interactions between malignancy and coagulation or fibrinolysis reactions in humans has clarified the pathogenesis of disseminated intravascular coagulation that occurs with malignancy and has revealed evidence for two distinct pathways of growth regulation based on production by tumor cells of initiators of thrombin formation versus plasminogen activators. We have proposed a preliminary classification of tumors (see Table 2) based on these interactions. Type I tumors are those in which the tumor cells are associated with an intact coagulation pathway that leads to thrombin formation at the tumor periphery but in which the tumor cells lack u-PA. Examples of tumors in this category include SCCL, malignant melanoma, and renal cell carcinoma. Type II tumors are those in which the tumor cells express u-PA but lack an associated coagulation pathway leading to thrombin formation. Examples of type II tumors include prostate cancer, colon cancer, breast cancer, and N-SCLC. Type III tumors are those that express neither of these pathways, or exhibit some other pattern of interaction. Obviously, this formulation must be regarded as hypothetical. However, this concept fits with the limited data available to date from clinical trials. More importantly, this hypothesis can be tested further by means of intervention aimed at interrupting pathways relevant to specific tumor types. Characterization of additional tumor types by the methods described should permit amplification of this classification of tumors and other patterns of interaction may be defined. Exploration of the coagulation-cancer interaction holds considerable promise for gaining new understanding of both the coagulation mechanism and tumor biology. Most intriguing is the prospect that imaginative approaches to cancer treatment may be devised that are not only relatively nontoxic and low cost, but also effective.

Platelet counts were evaluated in 714 patients with advanced non-small cell lung cancer (N-SCLC), small cell carcinoma of the lung (SCCL), and colon cancer entered to a clinical trial. Patients had not received prior chemotherapy. Platelet counts were not different in patients who had received radiation therapy prior to entry to the study. In comparison to the other tumor types, patients with N-SCLC demonstrated an increased prevalence of thrombocytosis (counts greater than 400,000/mm3), higher platelet counts at the time of entry to the study, higher over all mean platelet counts, relative preservation of high platelet levels during disease progression, and no relationship between platelet numbers and the amount of chemotherapy given. By contrast, platelet counts in patients with SCCL were negatively correlated with the absolute amount of cyclophosphamide and adriamycin given, and declined most dramatically with disease progression and death. Platelet numbers did not correlate with fibrinopeptide A or fibrin split product levels suggesting that disseminated intravascular coagulation or fibrinolysis may have had less influence on platelet numbers than certain other factors. By contrast, significant correlations were found for all three tumor types between platelet numbers and other indicators of bone marrow function including anemia, total leukocyte count, and absolute neutrophil count; and the fibrinogen level. Based upon these findings, we postulate that the host response to malignancy, possibly in the form of production of bone marrow-stimulating cytokines, may play a prominent role in regulation of platelet counts in these (and perhaps other) neoplasms, and that a particularly prominent and persistent degree of marrow stimulation exists in patients with N-SCLC.

Microangiopathic hemolytic anemia and thrombocytopenia secondary to disseminated intravascular coagulation is a well-described complication of widely metastatic carcinoma. The authors report four cases of gastric carcinoma, one case of colon cancer, and one case of adenocarcinoma of unknown primary in which the patient developed a syndrome analogous to thrombotic thrombocytopenic purpura, consisting of microangiopathic hemolytic anemia, thrombocytopenia, and renal failure without definite evidence of disseminated intravascular coagulation. In contrast to previous reports, postmortem examination in three of the cases revealed no recurrence or only microscopic foci of residual tumor. In the remaining three, there was clinical and pathologic evidence of grossly disseminated carcinoma. Also in contrast to previous cases, all patients evidenced azotemia and proteinuria at the onset of the syndrome and ultimately uremia was a contributing cause of death. Coagulation profiles showed prolonged thrombin times and elevated fibrin degradation products in four instances and did not distinguish the patients with grossly metastatic disease from those with no tumor or only microscopic residua. Circulating immune complexes containing carcinoembryonic antigen were found in the patient with metastatic colon carcinoma. The syndrome was clinically identical whether or not grossly metastatic tumor was present, and it should not be attributed to advanced disease without definite clinical or pathologic evidence of a recurrence.

Peritoneovenous shunt placement has been reported as a treatment of refractory ascites by general surgeons, but without a clearly established role. The authors successfully inserted shunts under ultrasonographic and fluoroscopic guidance in 12 patients who had symptomatic refractory ascites (nine men, three women; mean maintenance duration, 88.5 d). Nine patients had advanced liver cirrhosis (five with superimposed hepatoma). Other patients had stomach cancer, colon cancer, and complicated polycystic kidney disease. The mortality rate was 83%. Causes of death included bleeding from preexisting varices, sepsis, hepatic failure, rupture of hepatoma, and disseminated intravascular coagulation. The authors describe the feasibility, technical details, and short-term results of percutaneous peritoneovenous shunt placement.

We report a case of spinal destruction caused by chronic contained rupture of an abdominal aortic aneurysm (AAA). The patient was a 73-year-old man who had undergone coronary artery bypass grafting, sigmoidectomy for colon cancer, and axillofemoral bypass with AAA resection within months of each other, 3 years earlier. Abdominal computed tomography and magnetic resonance imaging showed destruction of the 12th thoracic and 1st lumbar vertebrae. The possibility of a metastatic spine tumor prompted us to consult the orthopedic surgeons, who recommended a spinal percutaneous needle aspiration biopsy. However, the cardiovascular surgeons diagnosed chronic contained rupture of an inflammatory AAA. The patient gradually improved with antimicrobial treatment, but died of disseminated intravascular coagulation the following year. The definitive diagnosis was confirmed by autopsy. We report this case for its educational value, considering the serious consequences that might have occurred had we attempted to biopsy the lesion.

Pseudomembranous colitis, an antibiotic-associated diarrhea, needs early diagnosis and treatment for the high fatality rate in severe cases. We report a case of pseudomembranous colitis following the use of antibiotics in febrile neutropenia (FN). A 74-year-old man with non-curative resected sigmoid colon cancer was treated with cefepime in FN induced by chemotherapy. Complications of diarrhea were seen on day 2. Paralytic ileus and disseminated intravascular coagulation were also complications. He was diagnosed as pseudomembranous colitis for Clostridium difficile toxin-positive. Vancomycin enemas were administered because oral administrations were impossible, and the effect was provided. Vancomycin enemas are an effective therapy for patients with severe pseudomembranous colitis unable to tolerate oral medications because of ileus.

We report a case of diffuse infiltrating carcinoma of the large intestine effectively treated by operation and chemotherapy. A 79-year-old woman with bone and liver metastases due to descending colon carcinoma underwent left hemicolectomy and colostomy. Pathological resected specimen findings showed a diffuse infiltrating carcinoma(lymphangiosis type). She re- ceived chemotherapy with 7 courses of mFOLFOX6, 8 courses of mFOLFOX6/bevacizumab(BV), and 5 courses of FOLFIRI/BV after surgical resection. The liver metastases reduced markedly as observed by abdominal CT scan. Twelve months later, DIC caused the death of the patient. Resection with lymphadenectomy and systemic chemotherapy may be effective for treatment of diffuse infiltrating carcinoma of the large intestine.

A 73-year-old man with advanced descending colon cancer and peritoneal metastases underwent a self-expandable metallic stent placement under fluoroscopic guidance on October 2007. The stent placement was successful without early complication. After 6 courses of FOLFOX4 followed by 7 courses of FOLFIRI, he received Bevacizumab-based chemotherapy from August 2008. In April 2009, he was admitted to our hospital with severe abdominal pain due to perforation of descending colon. Although emergent surgery was performed, he developed DIC and died on the 21 postoperative days. This case suggests that metallic stent placement for colorectal cancer cases might increase the risk of bowel perforation during Bevacizumab-based chemotherapy.

A 61-year-old male, who had been admitted to another hospital due to disseminated intravascular coagulation (DIC), was referred to our hospital. Total colonoscopy, abdominal dynamic CT and positron-emission tomography revealed bone metastasis and multiple lymphocytic metastases from transverse colon cancer in addition to disseminated carcinomatosis of the bone marrow (DCBM). We immediately performed chemotherapy with XELOX + bevacizumab and denosumab against DCBM from transverse colon cancer in order to avoid radical surgery. In addition, we initiated the administration of recombinant human soluble thrombomodulin for 1 week to treat DIC. The patient was able to tolerate and receive 4 cycles of chemotherapy without any severe side effects. After receiving the 4 cycles of treatment, he recovered from DIC, and the bone and multiple lymphocytic metastases disappeared.

Our patient was a 58-year-old man who was diagnosed with a large bowel obstruction caused by ascending colon cancer, together with multiple liver metastases for which a right hemicolectomy was performed. After the operation, he developed disseminated intravascular coagulation(DIC)and severe anemia. Bone marrow biopsy findings led to a diagnosis of disseminated carcinomatosis of the bone marrow caused by colon cancer. We administered S-1+oxaliplatin(SOX) and bevacizumab( BV)chemotherapy, which improved the DIC. The patient was discharged from the hospital. After a total of six courses of chemotherapy, the carcinoma became resistant. We changed the drug regimen and his clinical condition improved. He survived for 292 days from the onset of disease.
