Treating patients undergoing chemotherapy who display findings of liver toxicity, requires a solid understanding of these medications. It is important for any clinician to have an index of suspicion for liver toxicity and be able to recognize it, even on imaging. Cancer chemotherapy has evolved, and newer medications that target cell biology have a different pattern of liver toxicity and may differ from the more traditional cytotoxic agents. There are several hepatic conditions that can result and keen clinical as well as radiographic recognition are paramount. Conditions such as sinusoidal obstructive syndrome, steatosis, and pseudocirrhosis are more commonly associated with chemotherapy. These conditions can display clinical signs of acute hepatitis, liver cirrhosis, and even liver failure. It is important to anticipate and recognize these adverse reactions and thus appropriate clinical action can be taken. Often times, patients with these liver manifestations can be managed with supportive therapies, and liver toxicity may resolve after discontinuation of chemotherapy.

OBJECTIVENimotuzumab is a humanized monoclonal antibody targeted against epidermal growth factor receptor (EGFR). Recent clinical studies show that patients with malignant gliomas could benefit from nimotuzumab treatment. The aim of the present study was to evaluate the efficacy and side effects of nimotuzumab in combination with chemotherapy for patients with malignant gliomas.

METHODSThe patients received 200 mg of nimotuzumab infusion intravenously over 60 minutes once weekly for the first eight weeks and then once every two weeks until unacceptable toxicity or tumor progression occurred. Individualized chemotherapy was administered based on O(6)-methylguanine-DNA methyltransferase (MGMT) expression and previous chemotherapy responses in combined with nimotuzumab.

RESULTSFourteen patients received a total of 122 times of nimotuzumab ranging from 2 to 20 (median 7.5 times). Combined chemotherapy regimens included: continuous 21-day temozolomide (10 cases), standard 5-day temozolomide (2 cases), teniposide plus cisplatin (1 case), and teniposide plus nimustine (1 case). Partial response (PR) and stable disease (SD) were found in 3 patients (21.4%)and 6 patients (42.9%), respectively. Disease control rate (PR + SD) was 64.3%. The median progression-free survival (PFS) was 4 months (95%CI: 0.7 - 7.3) and PFS at 6 months was 30.6%. The most common toxicities include grade I-II neutropenia (2 cases), thrombocytopenia (2 cases), lymphopenia (1 case), nausea and vomitting (3 case) and asymptomatic transaminase increase (1 case). One patient developed grade IV neutropenia and thrombocytopenia. One patient developed nimotuzumab-related acneiform rash.

CONCLUSIONSNimotuzumab in combination with chemotherapy has moderate activity in patients with malignant gliomas and the toxicities are well tolerable, therefore, worth further investigation.

Temozolomide is an oral alkylating agent with clinical activity against glioblastoma multiforme (GM). It is generally well-tolerated and has few pulmonary side effects. We report a case of temozolomide-associated brochiolitis obliterans organizing pneumonia (BOOP) requiring very high-dose corticosteroid treatment. A 56-yr-old woman presented with a 2-week history of exertional dyspnea. For the treatment of GM diagnosed 4 months previously, she had undergone surgery followed by chemoradiotherapy, and then planned adjuvant chemotherapy with temozolomide. After the 1st cycle, progressive dyspnea was gradually developed. Chest radiograph showed diffuse patchy peribronchovascular ground-glass opacities in both lungs. Conventional dose of methylprednisolone (1 mg/kg/day) was begun for the possibility of BOOP. Although transbronchial lung biopsy findings were compatible with BOOP, the patient's clinical course was more aggravated until hospital day 5. After the dose of methylprednisolone was increased (500 mg/day for 5 days) radiologic findings were improved dramatically.

OBJECTIVETo study the safety and efficacy of three-dimensional conformal radiotherapy in combination with temozolomide in treatment of patients with diffuse brainstem glioma.

METHODSTwelve patients with MRI-confirmed diffuse brainstem glioma received 54 Gy three-dimensional conformal radiotherapy for 6 weeks with 1.8 Gy per fraction, 5 times per week. All of the patients were given daily oral temozolomide 75 mg/m(2) during radiotherapy. Four weeks after radiotherapy, all of the patients received 6 cycles of temozolomide, each cycle lasted 5 days with 28 days interval between each two cycles. 150 mg/m(2) of temozolomide was given for the first cycle for five days, followed by 200 mg/m(2) of the drug for the rest of the cycles if no significant drug-related toxicities were observed. Magnetic resonance imaging and laboratory tests were performed to evaluate the efficacy and adverse reactions.

RESULTSIn the 12 patients, CR was 1 case (8.3%), PR 6 cases (50.0%), SD 2 cases (16.7%), and PD 3 cases (25.0%). The overall clinical benefit rate was 75.0%. Progression-free survival rate was 75.0% (9/12) at 6 months and 50.0% (6/12) at 1 year. The one-year overall survival rate was 75.0%. There were no severe temozolomide-related toxicities.

CONCLUSIONSConcurrent temozolomide with three-dimensional conformal radiotherapy and followed by 6 cycles of temozolomide chemotherapy for diffuse brainstem gliomas have a better clinical efficacy, good tolerance and with no severe toxicities.

The purpose of this study was to develop a cost-effective protocol for the mobilization of peripheral blood stem cells (PBSC) in patients with malignancy. Thirty consecutive patients were randomized to mobilize PBSC with the late addition of a standard 250 microg dose of G-CSF (Neutrogen) from day 8 or early addition of the same dose of G-CSF from day 2, following cyclophosphamide (CY) 4 g/m2. The median yield of CD34+ cells from evaluated patients was 7.87 x 10(6)/kg (range, 2.06-27.25), collected in a median of four apheresis (range, 2-9). Target CD34 + cell doses > or = 2.0 x 10(6)/kg were achieved in all patients able to be evaluated. There were no statistically significant differences in CD34+ cell yields or toxicities. Overall engraftment occurred with median days to neutrophils > or = 0.5 x 10(9)/L or platelets > 20 x 10(9)/L of 11 and 17 days, respectively. However, the duration of G-CSF administration was markedly shorter in the late use of G-CSF group than in the early use of G-CSF group, with a median of 9 days compared with 15 days (p>0.001). PBSC harvesting after priming with CY plus delayed use of G-CSF made it a safe and cost-effective procedure.

This study evaluated the toxicity profiles of temozolomide in the treatment of malignant glioma as either concurrent or adjuvant chemotherapy. We retrospectively reviewed the medical records of 300 malignant glioma patients treated with temozolomide in two medical institutions in Korea between 2004 and 2010. Two hundred nine patients experienced a total of 618 toxicities during temozolomide therapy. A total of 84.8% of the 618 toxicities were Common Terminology Criteria for Adverse Events (CTCAE) grade 1 or 2, while 15.2% were grade 3 or 4. Among the hematologic toxicities, thrombocytopenia (13.7%), anemia (11.0%), and AST/ALT increases (7.0%) were common. Among the non-hematologic toxicities, nausea (44.3%), vomiting (37.0%), and anorexia (14.3%) were the three most common toxicities. There was no mortality due to temozolomide. Although temozolomide showed many types of toxicities, the majority of the toxicities were tolerable and of lower grade. Gastrointestinal troubles are the most common toxicities in Korean patients treated with temozolomide.

Combination chemotherapy and radiation therapy have contributed to the successful treatment of various cancer patients. But the development of second malignancies is an inevitable complication of long-term cytotoxic treatment. The most serious and frequent of such complications is acute myelogenous leukemia (AML). Therapy-related leukemia is generally fatal. Since the number of patients exposed to chemotherapy is increasing each year, the clinical significance of this entity cannot be underestimated. There have been many investigations of therapy-related leukemia, but in Korea published reports are rare. We describe four such cases, involving one older female with lung cancer and three children with acute lymphoblastic leukemia (ALL) and malignant lymphoma. Alkylating agents were used for chemotherapy, and in one case, topoisomerase II inhibitor. Irrespective of the causative agents, the latency periods were relatively short, and despite induction chemotherapy in two, all survived for only a few months. During the follow-up of patients treated for primary malignancies, the possibility of therapy-related leukemia should always be borne in mind.

OBJECTIVE: To study the efficacy and safety of 3-dimensional conformal radiotherapy combined with temozolomide (TMZ) for gliomas. METHODS: A total of 78 patients with pathologically confirmed glioma ( from September 2005 to March 2007) were postoperatively divided into 3 groups: a chemotherapy group (n=24), a radiotherapy group (n=25), and a comprehensive therapy group(n=29). The patients received temozolomide alone,3-dimensional conformal radiotherapy alone,3-dimensional conformal radiotherapy combined with temozolomide in the chemotherapy group,the radiotherapy group and the comprehensive therapy group respectively. The survival rate, progression-free survival, overall survival time and adverse reactions were observed. RESULTS: The 3-year survival rate in the comprehensive therapy group was significantly higher than that in the other two groups. The 3-year survival rates were 20.83%, 20.00%, and 41.38% in the chemotherapy group, the radiotherapy group and the comprehensive therapy group respectively. The progression-free survival time was 17.68,17.94, and 23.29 months and the average overall survival time was 20.28, 21.54, and 25.75 months in the chemotherapy group, the radiotherapy group and the comprehensive therapy group, respectively.The adverse reactions were mild and tolerable. CONCLUSION Three-dimensional conformal radiotherapy combined with temozolomide is more effective for gliomas than the simple 3-dimensional conformal radiotherapy and the temozolomide chemotherapy alone.
