Recombinant interferon alfa-2a (rIFN alpha-2a) synergistically augments the cytotoxic effects of the antimetabolite fluorouracil (5-FU) against two human colon cancer cell lines. A pilot clinical trial was initiated to determine whether this same combination of agents would show clinical utility greater than that expected with 5-FU alone in patients with advanced colorectal carcinoma. 5-FU was administered at 750 mg/m2/d for 5 days as a continuous intravenous infusion followed by weekly bolus therapy. rIFN alpha-2a was administered at 9 million units subcutaneously three times per week starting on day 1. Doses of 5-FU were modified for mucosal toxicities and myelo-suppression, and doses of rIFN alpha-2a were modified for fatigue and neurologic toxicities. Thirty-two previously untreated patients with advanced colorectal carcinoma were entered into a clinical trial. With the exception of one patient with a destructive lesion of the sacrum, all patients had metastases to visceral organs, abdominal wall, or pelvis. Twenty patients (63%) achieved a partial response, seven remained stable, and five had progressive disease. Mucosal toxicities limited delivery of full projected dose. Two patients died following episodes of watery diarrhea progressing to sepsis. A third died suddenly, secondary to an interstitial pneumonitis. The remainder of the toxicities were managed with dose reductions. At the median follow-up of 8 months, 23 of 32 patients remain alive. Nine are alive at 16 to 30+ months. The early results of this single-institution study are promising, but will require confirmation in a multi-institutional setting currently being conducted by the Eastern Cooperative Oncology Group.

KL-6, a circulating mucin-like glycoprotein, is a pulmonary adenocarcinoma-associated antigen and is also regarded as an indicator of disease activity of interstitial pneumonitis. KL-6 has extensive heterogeneous antigenic determinants and consists of multiple heterogeneous antigen molecules. We have searched for circulating KL-6-associated glycoproteins with superior diagnostic value to KL-6 as a tumor marker for pulmonary adenocarcinoma. A new murine monoclonal antibody EH-123 reacting with an asialosugar chain on KL-6 was established. A new KL-6-associated molecule detected by a bimonoclonal bideterminant sandwich assay using the EH-123 antibody as a catcher and horseradish peroxidase-labeled KL-6 as a tracer was designated as CAM 123-6. In 59% (22 of 37) of patients with pulmonary adenocarcinoma, serum levels of CAM 123-6 were abnormally elevated and the positive rate increased with the progression of clinical stage. Elevated levels were not detected in normal individuals or in patients with benign lung diseases, other histologic types of lung cancer, gastric cancer, colon cancer or breast cancer. CAM 123-6 was more specific to pulmonary adenocarcinoma than carcinoembryonic antigen (CEA), but the sensitivity of CAM 123-6 for pulmonary adenocarcinoma was similar to that of CEA. CAM 123-6 is a promising candidate as a serum tumor marker for pulmonary adenocarcinoma.

Alkaline phosphatase (ALP) isoenzyme analysis of 101,832 serum samples was performed by electrophoresis using cellulose acetate membrane, and abnormal bands at the alpha(1) and alpha(2) globulin positions were detected in 23 samples. The physicochemical properties of these abnormal ALP isoenzyme fractions were examined. In brief, the abnormal fractions were heat-sensitive and inhibited by L-phenylalanine, and neither sialic acid in their polysaccharide chains nor the glycosyl-phosphatidylinositol anchor was detected by the enzyme treatment. The physicochemical properties of abnormal ALP isoenzyme fractions detected in Patients 1 - 22 were similar to those of the adult small intestine type. However, the molecular weight of the adult small intestine type abnormal fractions was smaller than that of the normal fractions. These adult small intestine type abnormal bands at the alpha(1)- to alpha(2)-globulin positions, which were identified in the serum of Patients 1 - 22, were detected in elderly patients. Most of them had various basal diseases such as renal insufficiency, fracture, interstitial pneumonia, and chronic pancreatitis. Some of them had severe diseases such as rectal cancer, descending colon cancer, and septic shock. In Patient 23, the polysaccharide chain had sialic acid and was heat sensitive physicochemical properties that were similar to those of the Kasahara ALP variant.

We evaluated the efficacy and safety of modified FOLFIRI for patients with refractory advanced or recurrent colorectal cancer. Modified FOLFIRI was given 29 patients (21 men and 8 women, with a median age of 61.0 years) from 2 to 16 times (median 10.0). 19 out of 29 patients were colon cancer, and the other 10 were rectal cancer. 18 patients were administered as first-line chemotherapy, and 11 were more than second line. CPT-11 was administered at a dose of under 150 mg/m(2), to remain within the limits in Japan. The response to treatment was CR in 3 patients, PR in 8, and SD in 12. The response rate was 37.9%. Grade 4 hematologic toxicities included leukocytopenia in 2 patients, neutropenia in 7 and anemia in 1. Grade 3/4 non-hematologic toxicities included febrile neutropenia in 4 patients, anorexia in 3, fatigue in 3, and nausea, diarrhea and interstitial pneumonia in 1. Except in 2 patients, all reactions could be controlled with the use of G-CSF or by setting drug holiday. In summary, modified FOLFIRI is a safe and effective regimen even at a dose of under 150 mg/m(2), of CPT-11. It can be given with good tolerance for patients with refractory advanced or recurrent colorectal cancer on an outpatient basis with due care especially for neutropenia.

Information concerning the pulmonary toxicity of oxaliplatin with infusional 5-fluorouracil plus leucovorin (FOLFOX) is very limited. We herein report the case of a patient with FOLFOX-induced interstitial pneumonia. An 82-year-old man with unresectable colon cancer liver metastases was referred to our department for chemotherapy with the FOLFOX protocol. After the administration of ten cycles, he visited our outpatient clinic with a 2-week history of coughing and shortness of breath; he was afebrile. A chest radiograph showed reticular shadows with ground-glass opacities mainly involving the middle and lower zones of the right lung. Computed tomography depicted ground-glass opacities with superimposed reticulation in the right lung. A diagnosis of FOLFOX-induced interstitial pneumonia was made based on the clinical course and imaging findings. The symptoms disappeared within 3 days after the cessation of the FOLFOX regimen and the initiation of high-dose corticosteroid treatment. Two months after the initiation of the corticosteroid treatment, complete remission of the radiological abnormalities was confirmed; thereafter, interstitial pneumonia did not recur despite the reintroduction of 5-fluorouracil/leucovorin alone, suggesting that 5-fluorouracil/leucovorin alone was not responsible for the development of the interstitial pneumonia. Thus, oxaliplatin, alone or in combination with 5-fluorouracil/leucovorin, may have caused the interstitial pneumonia in this patient. Once interstitial pneumonia has occurred, cessation of the regimen is mandatory, and high-dose corticosteroid treatment is commonly given to rescue patients from this potentially lethal complication.

A 64 -year-old female received oral S-1 chemotherapy followed by mFOLFOX6 chemotherapy for postoperative liver and lung metastasis of sigmoid colon cancer. The tumor progression was observed after twelve courses of mFOLFOX6 chemotherapy, and then FOLFIRI+bevacizumab chemotherapy was performed. After two courses of FOLFIRI+bevacizumab chemotherapy, leucopenia was observed. The chemotherapy was then discontinued and G-CSF was administered. Two days later she complained of high fever and dry cough, and was admitted to the hospital. A diffuse ground-glass appearance of bilateral lung was observed on chest X-ray and CT. Drug-induced interstitial pneumonitis was suspected, and Pneumocystis carini pneumonia was considered in the differential diagnosis. Oral administration of prednisolone and sulfamethoxazole/trimethoprim did not improve the symptoms, so steroid pulse therapy was performed. Steroid pulse therapy improved respiratory symptoms, but CT findings did not change remarkably. After nine weeks in the hospital, she was discharged with home oxygen therapy. Interstitial pneumonitis induced by FOLFIRI+bevacizumab chemotherapy is rare, but the number of cases may increase with increased use of this regimen. The possibility of interstitial pneumonitis should always be considered when the patient presents with a respiratory disorder while receiving systemic chemotherapy.

We report a case of acute interstitial pneumonitis and respiratory failure occurring in a 69-year-old, previously healthy patient receiving FOLFOX regimen plus cetuximab for colon cancer. Association between this chemotherapy regimen and interstitial pneumonitis is rarely reported in the literature. We treated the patient with pulse steroid therapy, and improvement in respiratory function and decreased pulmonary infiltrations demonstrated good response to steroids use. However, the patient ultimately expired from respiratory complications after 98 days from admission, possibly due to secondary infection. Both oxaliplatin and cetuximab have rarely been associated with interstitial pneumonitis, and our case may serve as an important reference for physicians notice in patients receiving these chemotherapeutic agents.

We report a case of a 58-year-old man suffering from advanced colon cancer with liver metastases. After the sigmoidectomy and left lateral segmentectomy, mFOLFOX6+bevacizumab was initiated. The mFOLFOX6+bevacizumab therapy was performed for 15 courses, but it was stopped because of an increase in serum levels of tumor markers(CEA and CA19-9). For the next treatment, FOLFIRI+panitumumab therapy was performed. At the beginning of the second course, he suffered from dyspnea. Computed tomography showed ground-glass opacities and traction bronchiectasis in both lung fields. He was diagnosed with interstitial pneumonitis induced by irinotecan or panitumumab. Corticosteroid therapy consisting of methyl- prednisolone(1 g/day)administered for three days was significantly effective for treating respiratory failure. Two courses of the therapy were performed, and he was discharged without aftereffects. As with other EGFR tyrosine kinase inhibitors, the frequency of interstitial pneumonitis induced by irinotecan in Japan may increase to European and American levels.

Case 1: A 69-year-old man was diagnosed with rectal cancer and liver metastasis. After low anterior resection, mFOLFOX6 plus cetuximab therapy was started for resection of the liver metastasis. However, he had to forgo liver resection because he developed acute exacerbation of interstitial pneumonitis (IP) after 6 courses of chemotherapy. Despite beginning the second-line treatment with mFOLFOX6 plus bevacizumab, he died in June 2012. Case 2: A 71-year-old man had undergone sigmoidectomy for sigmoid colon cancer in 2005, and right lower lobe partial resection for metastatic lung cancer in 2006. Although radiofrequency ablation or transcatheter arterial chemoembolization had been performed for multiple liver metastases several times since 2007, his multiple liver metastases were uncontrollable. Therefore, FOLFOX4 therapy was started in 2010, and mFOLFOX6 plus cetuximab therapy was substituted for FOLFOX4 therapy in 2011. The patient died in March 2012 due to the rapid development of IP, and thus, it appears that IP was the cause of death in both patients. The general condition, including pulmonary function, of patients at risk of IP must be checked before starting cetuximab therapy for metastatic colorectal cancer.

Krebs von den Lungen-6 (KL-6) is a high-molecular-weight glycoprotein which is elevated in serum of patients with interstitial pneumonia (IP). Serum KL-6 level is clinically used for the diagnosis of IP as well as the evaluation of its disease activity. KL-6 is originally identified when exploring novel soluble antigens in patients with lung cancer, and is known to be elevated in patients with several malignant tumors. The risk of malignant tumors is high in IP patients with polymyositis and dermatomyositis (PM/DM), and follow-up of KL-6 levels may allow earlier detection of such tumors. However, to date, there are only a few reports showing the usefulness of following-up serum KL-6 levels for finding malignant tumors in IP patients with PM/DM. Here, we described the first patient in whom increased serum KL-6 led to the diagnosis of colon cancer during follow-up of DM-associated IP.
