We reported the results of phase I study with CPT-11 and S-1 (IRIS) in advanced gastric cancer (AGC) patients at ASCO 2002. Now I present an outline of this phase I/II trial. A combined treatment of IRIS (CPT-11 + S-1) was given to the AGC patients who had not received prior chemotherapy. S-1 was orally administered twice a day for 14 days, and CPT-11 was administered as a 90-minute intravenous infusion on days 1 and 15. This schedule was repeated every 4 weeks. Fifteen patients were registered in this phase I study and 9 patients were added in this phase II study. Non-hematological toxicities were almost classified as grade 2 or lower, except for grade 3 nausea and grade 3 dermatitis of level 2. These adverse events were manageable by administering anti-emetic drugs and a drug rest. As for hematological toxicities, grade 4 neutropenia occurred with one patient at level 1 and level 2 in phase I. And grade 4 neutropenia occurred with four patients at level 2 in phase II. However, they recovered after the drug rest, and we could continue the administration based on the standard dose modifications. These side effects were tolerable, and the overall response rate was 54.2%. MST of this regimen is 581 days. The IRIS treatment is effective and tolerable for outpatient treatments.

We report a successful case of chemotherapy accompanied with grade 4 adverse events for unresectable advanced gastric cancer. A 73-year-old man was admitted to our hospital with complaint of abdominal pain in July 2007. The detailed examination had revealed advanced gastric cancer, lymph node metastasis, and multiple hepatic metastases. Performance status (PS) was level 0, and oral intake of medications was possible. Combined therapy with S-1 and CPT-11 (IRIS regimen) was performed from August as the first-line therapy. As a consequence of first course, grade 4 hematological adverse events (AEs) appeared and an urgent hospitalization was required. With whole body supportive care against grade 3 non-hematological AEs, which were diarrhea, anorexia, and fatigue, G-CSF, the broad-spectrum antibiotic were administered at the clean-room. After 1 course, cyto-reductive change was confirmed at the primary lesion and hepatic metastases. We continued the same regimen with dose reduction (S-1: 2 level dose down, CPT-11: 10% dose down). Although the regression of hepatic metastases was seen, we repeated the dose reduction of CPT-11 and the dose down level was reached to 40% for prolonged grade 2 neutropenia. After 6th courses, complete responses at primary lesion, lymph node, and hepatic metastases were achieved. The patient has received the same regimen of 9th course continuously as an outpatient, and CR has been maintained.

The immune reconstitution inflammatory syndrome is a heterogeneous collection of pathological manifestations attributed to an excessive and deregulated immune response to various infectious and non-infectious pathogens consecutive to the modification of immune status. Mycobacteria and mycoses in the context of an HIV infection are the main causes of IRIS but this syndrome is also observed with many infectious pathogens in the context of auto-immune or inflammatory diseases. An excessive specific CD4 Th1 response leading to delayed hypersensitivity with imbalanced effector and regulatory cellular immune responses is suggested. The role played by host polymorphisms remains to be investigated. The emergence of a unique syndrome gathering multiple immune-depression/reconstitution such as HIV infection and antiretroviral therapy, decrease of immune depression in transplant, recovery from neutropenia after chemotherapy for cancer, and even post-partum period, could link various specialties and help to better understand physiopathology which is crucial to elaborate preventive therapies.

Although imatinib has become the current standard treatment for chronic myeloid leukemia (CML), there is limited information regarding its efficacy and safety among Japanese patients. We therefore conducted a prospective multi-center open-label study of imatinib for Japanese patients with newly diagnosed chronic-phase CML (CP-CML). A total of 107 patients were enrolled and treated with imatinib at an initial daily dose of 400 mg. Eighty-three patients completed 3 years of study treatment. The cumulative rates of major cytogenetic response and complete cytogenetic response (CCyR) were 90.9 and 90.2% at 3 years, respectively. The safety profile was not very different from that reported in the IRIS study, although grade > or =3 neutropenia occurred relatively frequently (31.8 vs. 14.3%). Only seven patients discontinued the study due to adverse events, as did four patients due to insufficient efficacy. The 3-year probabilities of overall survival and progression-free survival were 93.2 and 91.4%, respectively. Higher average daily doses (i.e., > or =350 mg) were significantly associated not only with higher rates of achieving CCyR, but also with longer duration of CCyR. These findings confirm the clinical utility of imatinib in Japanese patients with newly diagnosed CP-CML, and suggest detrimental effect of low average daily dose on treatment results.

Immune reconstitution inflammatory syndrome occurs in patients with rapidly recovering immune systems in response to antigens (viable pathogens, nonviable pathogen debris, host antigens or tumor antigens). The acronym IRIS, Greek for spectrum of color, is often used for immune reconstitution inflammatory response syndrome and reflects the wide spectrum of clinical manifestations associated with this entity. This is a case report of an acute myelogenous leukemia patient with neutropenia after cytotoxic chemotherapy who developed severe dyspnea and new pulmonary infiltrates temporally associated with rapid neutrophil recovery. The incidence, pathogenesis, clinical presentation and therapy of IRIS will be discussed in this article. There should be an increased awareness of the many clinical manifestations of IRIS in hematologic malignancy patients with rapid neutrophil recovery after cytotoxic chemotherapy, in order to allow prompt institution of corticosteroids which could be life saving.
