RESUMO

Aims: The addition of aflibercept to the fluorouracil and irinotecan (FOLFIRI) regimen significantly improved clinical outcomes in patients with metastatic colorectal cancer (CRC) previously treated with oxaliplatin. We aimed to investigate the efficacy and safety of second-line FOLFIRI and aflibercept combination in patients with metastatic CRC in real-life experience. Materials and Methods: Four hundred and thirty-three patients who treated with FOLFIRI and aflibercept in the second-line were included in the study. The clinical and pathological features of the patients were recorded retrospectively. Survival (overall and progression-free survival [PFS]), response rates, and safety data were analyzed. Results: The median age was 61. Majority of patients (87.5%) received first-line bevacizumab and 10.1% of patients received anti-epidermal growth factor receptor agents. About 80% of patients had KRAS, 18.6% of patients had NRAS, and 6.4% of patients had BRAF mutations. The median OS was 11.6 months (95% confidence interval [CI], 10.6-12.6) and the median PFS was 6 months (95% CI, 5.5-6.5). About 4.6% of patients had complete response and 30.6% of patients had partial response as best tumor response. Grade 1-2 toxicities were seen in 33.4% of patients, while grade 3-4 toxicities were recorded in 27% of patients. Eight patients (2%) died due to treatment toxicity. Conclusions: Overall and PFS were similar in routine clinical practice compared to phase III pivotal VELOUR trial. However, response rates were found to be higher. It was observed that there were fewer adverse events compared to the VELOUR trial.

RESUMO

BACKGROUND: Atezolizumab (ATZ) has demonstrated antitumor activity and manageable safety in previous studies of patients with metastatic platinum-resistant urothelial carcinoma. However, the response rate of Atezolizumab was modest. In the current study, we evaluated the pretreatment prognostic factors for overall survival in patients with metastatic urothelial carcinoma who have progressed after first-line chemotherapy in the Expanded-Access Program of Atezolizumab. PATIENTS AND METHODS: In this study, we present a retrospective analysis of 113 patients with urothelial cancer treated with ATZ after progression on first-line chemotherapy. Data of the patients was obtained from patient files and hospital records. Eligible patients included metastatic urothelial carcinoma patients treated with at least one course of ATZ. Univariate analysis was used to identify clinical and laboratory factors that significantly impact OS. Variables were retained for multivariate analysis if they had a statistical relationship with OS (p < 0.1), and then included a final model of p < 0.05. RESULTS: The median follow-up duration was 23.5 months. Of the patients, 98 (86.7%) were male and 13.3% were female. The median age was 65 years of age (37-86). In univariate analysis, primary tumor location in the upper tract, increasing absolute neutrophil count (ANC), increasing absolute lymphocyte count, neutrophil-to-lymphocyte ratio (NLR) > 3, liver metastases, baseline creatinine clearance less (GFR) than 60 ml/min, Eastern Cooperative Oncology Group (ECOG) performance status (1 ≥), and hemoglobin levels below 10 mg/dl were all the significantly associated with OS. Three of the five adverse prognostic factors according to the Bellmunt criteria were independent of short survival: liver metastases HR 3.105; 95% CI 1.673-5.761; p < (0.001), ECOG PS (1 ≥) HR 2.184; 95% CI 1.120-4.256; p = 0.022, and Hemoglobin level below 10 mg/dl HR 2.680; 95% CI 1.558-4.608; p < (0.001). In addition, NLR > 3 hazard ratio [HR] 2.092; 95% CI 1.031-4.243; p = 0.041 and GFR less than 60 ml/min HR 1.829; 95% CI 1.1-3.041; p = 0.02, maintained a significant association with OS in multivariate analysis. CONCLUSIONS: This model confirms the Bellmunt model with the addition of NLR > 3 and GFR less than 60 ml/min and can be associated with clinical trials that use immunotherapy in patients with bladder cancer.

RESUMO

Aim: To assess the efficacy and tolerability of the first-line treatment options for hormone-refractory prostate cancer patients with visceral metastases. Materials & methods: The records of 191 patients diagnosed with hormone-refractory prostate cancer with visceral metastases were analyzed retrospectively. Results: Docetaxel was administered to 61.2% (n = 117), abiraterone to 14.2% (n = 27) and enzalutamide to 9.4% (n = 18) as the first-line treatment. The median survival of the patients receiving docetaxel, abiraterone and enzalutamide as the first-line treatment during the hormone-refractory period was 15 (95% Cl: 12.9-17) months, 6 (95% Cl: 1.8-10.1) months and 11 (95% Cl: 0.9-23.1) months (p = 0.038), respectively. Conclusion: The present study established a statistically significant difference in favor of docetaxel in terms of overall survival and progression-free survival.


Lay abstract The optimal therapeutic option for castration-resistant prostate cancer (CRPC) patients with visceral metastases is unknown. We assessed the efficacy and tolerability of the first-line treatment options for CRPC patients with visceral metastasis. One hundred ninety-one patients diagnosed with CRPC with visceral metastases were included in the study. The present study established a statistically significant difference in favor of docetaxel in terms of overall survival and progression-free survival between first-line docetaxel, abiraterone and enzalutamide treatments in CRPC patients with visceral metastases. For patients who cannot undergo chemotherapy, enzalutamide, among novel androgen pathway inhibitors, may be the most appropriate option, given its numerical, although statistically insignificant, difference in overall survival and its fewer side effects compared with abiraterone.

RESUMO

BACKGROUND: Atezolizumab (ATZ) has demonstrated antitumor activity and manageable safety in previous studies in patients with locally advanced or metastatic platinum-resistant urothelial carcinoma. OBJECTIVE: To compare the real-life experience and data of clinical trials on ATZ treatment in metastatic urothelial carcinoma. DESIGN, SETTING, AND PARTICIPANTS: Patients with urothelial cancer treated with ATZ after progression on first-line chemotherapy from an expanded access program were retrospectively studied. Data of patients were obtained from their files and hospital records. Safety was evaluated for patients treated with at least one cycle of ATZ. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The primary endpoint was objective response rate (ORR). The secondary endpoints are overall survival (OS), progression-free survival (PFS), duration of response, and safety profile of patients. Kaplan-Meier methods were used to calculate median follow-up and estimate PFS and OS. RESULTS AND LIMITATIONS: Data of 115 enrolled patients were analyzed. Most of the patients (92.3%, n = 106) had received chemotherapy regimen only once prior to ATZ. The median follow-up duration was 23.5 mo. The complete response rate, partial response rate, and ORR were 8.7% (n = 10), 20.0% (n = 23), and 28.7% (n = 33), respectively. The median duration of response was 20.4 mo (95% confidence interval [CI], 6.47-28.8). Of the 33 patients who responded to treatment, 60% (n = 20) had an ongoing response at the time of the analysis. PFS and OS with ATZ were 3.8 mo (95% CI, 2.25-5.49) and 9.8 mo (95% CI, 6.7-12.9), respectively. All-cause and any-grade adverse events were observed in 113 (98%) patients. Of the patients, 64% experienced a treatment-related adverse event of any grade and 24 (21.2%) had a grade 3-4 treatment-related adverse event. Limitations of the study included its retrospective design, and determination of treatment response based on clinical notes and local radiographic studies. CONCLUSIONS: In these real-life data, ATZ was effective and well tolerated in patients with metastatic urothelial carcinoma who have progressed with platinum-based first-line chemotherapy. ATZ is an effective and tolerable treatment for patients with locally advanced or metastatic platinum-resistant urothelial carcinoma in our study, similar to previously reported trials. PATIENT SUMMARY: Atezolizumab is effective and well-tolerated in patients with metastatic urothelial cancer who progressed with first-line chemotherapy, consistent with the outcomes of the previous clinical trials in this setting.

RESUMO

PURPOSE: We aimed to study the inflammatory parameters of complete blood count in breast cancer cases. MATERIALS AND METHODS: This retrospective study covered 178 breast cancer patients and 107 age and body mass index matched healthy women. Complete blood count parameters, neutrophil/lymphocyte ratio (NLR), platelet/ lymphocyte ratio (PLR) and MPV/platelet were analyzed. RESULTS: The leukocyte, neutrophil and neutrophil/ lymphocyte ratio were higher in the patient group (p values 0.001, 0.0001 and 0.0001, respectively) while haemoglobin and hematocrit were higher in the control group (p=0.0001 for both). Logistic regression analysis showed that elevated neutrophils and platelet distribution width (PDW) (OR: 0.627, 95%CI: 0.508-0.774, p=0.001 and OR: 1.191 95%CI: 1.057-1.342 p=0.003) were independent variables for predicting breast cancer. The cut- off value for the neutrophil/lymphocyte ratio was 2.56. CONCLUSIONS: According to our study results, neutrophil levels as part of complete blood count may be used as an independent predictor of breast cancer risk.

RESUMO

Sorafenib is a multi-targeted tyrosine kinase receptor inhibitor used to treat patients with advanced gastrointestinal stromal tumors (GISTs). The present study evaluated the efficacy and tolerability of sorafenib therapy for patients with GISTs. Between January 2001 and November 2012, 25 patients, from multiple centers, who had received sorafenib as the third- or fourth-line treatment for GISTs were investigated retrospectively. In total, 17 patients were male and eight were female. The median age was 54.0 years (range, 16-82 years). From the patients, 21 received imatinib for longer than six months and four received it for less than six months. The clinical benefit rate of sorafenib was 40.0%. Treatment-related adverse events were reported in 72% of patients. These adverse events were generally mild to moderate in intensity. The median progression-free survival (PFS) and overall survival (OS) times of the patients who received sorafenib were 7.2 and 15.2 months, respectively. The duration of imatinib usage was an independent prognostic factor for PFS and OS. Sorafenib is an effective treatment in patients with GISTs showing a clinical benefit rate of 40.0% and an acceptable tolerability.

RESUMO

There is no established standard salvage chemotherapy in the second-line setting for patients with advanced gastric cancer (AGC) pre-treated with platinum and taxane-based chemotherapy. Our study aims to evaluate the safety and efficacy of FOLFIRI regimen (irinotecan with leucovorin and bolus and continuous infusion with 5-fluorouracil) as a salvage chemotherapy regimen in patients with AGC. Medical records of 97 patients with AGC who received second-line FOLFIRI regimen between March 2006 and February 2011 were examined. Complete and partial responses were observed in 3 (3.1%) and 23 (23.7%) patients, respectively. The median time to progression (TTP) was 3.5 months (95% CI: 2.4-4.6) and the median overall survival (OS) was 10.5 months (95% CI: 8.8-12.2). The most common observed grade 3/4 toxicities were neutropenia (23.7%), diarrhea (6.2%), and stomatitis (5.2%). FOLFIRI regimen is safe and effective in the second-line treatment of AGC patients pre-treated with cisplatin and taxanes.

RESUMO

PURPOSE: To assess the safety and efficacy of a gemcitabine plus docetaxel regimen as a second line therapy for patients with advanced soft tissue sarcoma (STS) resistant to doxorubicin and ifosfamide-based therapy. PATIENTS AND METHODS: Medical records of 64 patients with advanced STS who received gemcitabine plus docetaxel regimen as a second line treatment between May 2006 and June 2011 were examined. All patients had been previously treated with doxorubicin plus ifosfamide-based regimen at first line setting. Patients received gemcitabine 900 mg/m2 on days one and eight intravenously over 90 minutes, followed by docetaxel 75 mg/m2 on day eight intravenously over one hour. Cycles were repeated every 3 weeks. RESULTS: The male-to-female ratio was 37/27 and the median age was 44 years (range; 19-67 years). Objective responses were observed in 13 (20.3%) patients (2 CR, 11 PR) and stable disease in 21 (32.8%). Total clinical benefit (CR+PR+SD) was observed in 34 (53.1%). Median overall survival (OS) was 18 months (95% confidence interval (CI):12.1-23.9) and Median time to progression (TTP) was 4.8 months (95% CI: 3.6-6). A total of 243 cycles of chemotherapy were administered. The median number of cycle was 3 (range; 1-11). The most common grade 3-4 hematologic toxicity was neutropenia (35.9%). The most common nonhematologic toxicities consisted of nausea/vomiting (37.5%), mucositis (32.8%), peripheral neuropathy (29.7%), and fatigue (26%). There was no toxicity-related death. CONCLUSION: The combination of gemcitabine plus docetaxel is an active and tolerable regimen as a second line therapy for patients with advanced soft tissue sarcoma who have failed doxorubicin and ifosfamide-based therapy.

RESUMO

AIMS: To evaluate activity and toxicity of cisplatin plus docetaxel combination in the first-line treatment of chemotherapy-naive patients with metastatic non-small cell lung cancer. PATIENTS AND METHODS: Between October 2004 and July 2008, 186 patients with metastatic non-small cell lung cancer treated with first-line cisplatin plus docetaxel were retrospectively evaluated in 7 centers. The chemotherapy schedule consisted of cisplatin, 75 mg/m(2) iv infusion, and docetaxel, 75 mg/m(2) iv infusion on day 1, every 3 weeks. RESULTS: Median age was 56 years (range, 28-75). Eighteen patients (9.7%) were females and 168 (90.3%) were males, with a median ECOG performance status of 1 (range, 0-2). A total of 833 cycles of chemotherapy was administered (median, 4 cycles; range, 1-6). Two patients (1.1%) achieved clinical complete response, 77 patients (41.4%) partial response, and 66 patients (35.5%) stable disease. Median time to disease progression was 6 months (95% CI, 5.54-6.46). Median overall survival was 14.6 months (95% CI, 11.47-17.73). One- and 2-year overall survival was 55.2% and 19.7%, respectively. The most common grade 3-4 hematological toxicities were neutropenia (n = 32, 17.2%) and anemia (n = 4, 2.2%). CONCLUSIONS: The cisplatin plus docetaxel combination was effective and safe in the first-line treatment of patients with metastatic non-small cell lung cancer.

RESUMO

BACKGROUND: Temozolomide is the major drug in the treatment of malignant gliomas. Radiation induced necrosis can behave radiologically and clinically like a recurrent tumor. The major problem is the differentiation between recurrence and radiation injury especially in early phases of treatment. The aim of this study was to evaluate the patients receiving temozolomide showing early clinical or radiological progression and impact of early necrosis on follow-up. PATIENTS AND METHODS: We retrospectively evaluated medical records of 67 patients with malignant glioma receiving temozolomide. All patients received concomitant radiotherapy and temozolomide followed by adjuvant temozolomide. In case of any radiological or clinical progression, MRI spectroscopy evaluation was used to confirm tumoral progression. RESULTS: Radiological or clinical progression was observed in 17 (25.4%) patients. Early radiation induced necrosis was diagnosed in 4 of 17 patients (23.5%) by surgery (n=3) and MRI spectroscopy (n=1). The observed incidence of pseudoprogression was 4 in 67 (6%) patients. Patients with diagnosis of early radiation injury had median progression-free survival of 7 months compared to 5 months in patients without radiation damage (p=0.004). However, there was no statistically significant difference in terms of overall survival between groups. CONCLUSION: Temozolomide can cause early radiation induced injury which can mimic progressive tumor. Although the discrimination between two entities results in the accurate evaluation of response to therapy and benefits those patients, it did not affect overall survival. MRI spectroscopy is a valuable tool to define early radiation necrosis and should be further evaluated in larger prospective studies.

RESUMO

BACKGROUND: Male breast cancer is an uncommon disease. Moreover, synchronous bilateral breast cancer is extremely rare in men. The management is still undefined, although it shows similarities to breast cancers in women. CASE REPORT: We report the case of a 66-year-old male patient who presented with palpable bilateral breast masses. Synchronous bilateral breast cancer was diagnosed with imaging studies and tru-cut biopsy. Histopathological examination revealed bilateral early-stage breast cancer. None of the possible predisposing factors, including hormonal and hereditary history, could be detected. Following bilateral modified radical mastectomy, the patient received adjuvant chemotherapy with tamoxifen. The pertinent literature is reviewed. CONCLUSION: More studies are warranted to better identify possible risk factors for male breast cancers.

RESUMO

PURPOSE: Bevacizumab-based chemotherapy has become the standard of care in metastatic colorectal cancer (MCRC). We aimed to measure the levels of serum soluble FAS, FASL, tumor necrosis factor-related apoptosis-inducing ligand (TRAIL), and its death receptors DR4 and DR5 in MCRC patients and to define prognostic significance of these parameters in response to bevacizumab in these patients. PATIENTS AND METHODS: The levels of these parameters in serum samples were quantified by a commercially available ELISA kit in 31 MCRC patients before and after 2 cycles of therapy and 25 healthy controls. RESULTS: Pretreatment sFAS levels in MCRC patients was significantly lower than the levels of controls (p = 0.043). There was no significant difference in sFAS and sFASL levels in MCRC patients before and after bevacizumab-based treatment. There was no significant difference in sFAS/sFASL ratio in MCRC patients before and after treatment and controls. Soluble DR5 levels were significantly higher in pretreatment serum samples compared with controls (p = 0.008). However, pretreatment sTRAIL and sDR4 levels were similar to the levels of controls. There was no significant difference in sTRAIL, sDR4, and sDR5 levels in MCRC patients before and after treatment. When patients were grouped according to treatment response (responders vs. non-responders), post-treatment sFAS/sFASL ratio was significantly lower in responding patients compared with non-responders (p = 0.029). Significant correlations were observed between post-treatment sFASL and sDR4, sFAS and sTRAIL, sTRAIL and sFAS/sFASL ratio, and sFASL and sDR5. CONCLUSION: Non-significant changes in apoptotic markers with bevacizumab-based chemotherapy showed that they have no prognostic significance in MCRC patients. Significant change in sFAS/sFASL ratio according to treatment response could be an indicator of chemosensitivity.

RESUMO

The aim was to evaluate the clinical findings of patients who admitted to the hospital with the diagnosis of grayanotoxin/mad honey poisoning. Thirty-three patients were included in this study. Three patients were female (9%) and the others male (91%). Median age of patients was 52 (42-68). The most frequently observed findings were sinus bradycardia (91%), nausea-vomiting (81.8%), and dizziness (78.8%). Average heart rate was 55.35 +/- 6.72 beats/min. Mean systolic and diastolic blood pressures were 77.86 +/- 16.64 mmHg and 46.42 +/- 12.30 mmHg, respectively. Mad honey poisoning is an important problem that is life-threatening in the Black Sea region of Turkey.

RESUMO

BACKGROUND: Platinum, antracyline, and fluoropyrimidine combination chemotherapy has been widely used as a first-line treatment for advanced gastric cancer (AGC). In the present study, we determined the efficacy and the safety of docetaxel and oral etoposide as second-line combination chemotherapy after failure of commonly used combination regimens in AGC. METHODS: Patients with histologically proven gastric cancer and measurable metastatic disease received docetaxel 75 mg/m(2) as a 1-h intravenous infusion on day 1, and oral etoposide 50 mg/m(2) once daily on days 1-5, every 3 weeks until disease progression or unacceptable toxicities. RESULTS: Between June 2006 and September 2008, 32 patients, of median age 60 years (range 32-77 years) were included in the study. Overall response rate was 9.4% and 31.3% of patients achieved a stable disease. Median progression-free survival was 3 months (95% CI, 2.5-3.5). Median overall survival was 6 months (95% CI, 3.8-8.2) with 16.9% 1-year survival rate. Grade 3-4 toxicities included neutropenia (28.8%), febrile neutropenia (18.8%), thrombocytopenia (3.1%), nausea and vomiting (15.6%), diarrhea (9.4%), and mucositis (6.2%). CONCLUSION: Docetaxel and oral etoposide combination was moderately effective and safe in appropriately selected AGC patients after failure of platinum- and fluoropyrimidine-based combination regimens.

RESUMO

AIMS: To evaluate preoperative concomitant chemoradiation using cisplatin plus docetaxel followed by consolidation chemotherapy in patients with unresectable locally advanced non-small cell lung cancer (NSCLC). PATIENTS AND METHODS: Medical records of patients with locally advanced unresectable NSCLC (stage IIIA and IIIB) treated with concomitant chemoradiotherapy using cisplatin + docetaxel combination followed by consolidation chemotherapy were retrospectively evaluated. All the patients were consecutively treated. Chemotherapy consisted of weekly cisplatin 20 mg/m(2) and docetaxel 20 mg/m(2) during radiotherapy. Radiotherapy dose was 58-66 Gy given in 2 Gy fractions, 5 days per week. The patients were subsequently referred to surgery if adequately downstaged. Consolidation chemotherapy using cisplatin and docetaxel both at doses 75 mg/m(2) every 3 weeks followed local therapy in all patients. RESULTS: A total of 54 patients were evaluated (49 males, 5 females with a median age of 58 years; 41 [75.9%] stage IIIB and 13 [24.1%] IIIA). Twelve patients (22.2%) achieved pathologic complete response and 20 (37%) partial response. Downstaging was possible in 32 patients (59.3%). Twenty-six patients (48.1%) were operated after concomitant chemoradiotherapy (pneumonectomy [n = 2], lobectomy [n = 12], and wedge resection [n = 12]). Toxicity was tolerable. Median progression-free survival and overall survival (OS) for the entire cohort were 14 and 22 months, respectively. In resected patients (n = 26), median PFS and OS have not been reached with a median follow-up duration of 24 months. CONCLUSION: Preoperative concomitant chemoradiation using weekly cisplatin and docetaxel followed by surgery and consolidation chemotherapy is effective and well tolerated in patients with unresectable locally advanced NSCLC.

RESUMO

BACKGROUND: Treatment of patients with metastatic colorectal cancer (MCRC) previously exposed to oxaliplatin-based regimen is challenging. Efficacy and toxicity of bevacizumab plus irinotecan-based regimens were assessed in the second-line treatment of MCRC patients. PATIENTS AND METHODS: Forty patients with a median age of 53 years (range, 31-75) were retrospectively evaluated. Patients progressing or relapsing after treatment with oxaliplatin-based regimens were given bevacizumab 5 mg/kg every 2 weeks in combination with irinotecan-based regimens. All patients had previously received oxaliplatin either in the adjuvant setting (n = 8) or for metastatic disease (n = 32). RESULTS: Three patients achieved a complete response (7.5%), 5 partial responses (12.5%) and 14 (35%) stable disease resulting in an overall response rate of 20%. Median progression-free survival was 6 months (95% CI, 4.0-8.0) with a median overall survival of 14 months (95% CI, 10.2-17.8). One-year survival rate was 55.9%. Grade 3-4 toxicities were as follows: neutropenia (n = 15, 37.5%), febrile neutropenia (n = 2, 5%), diarrhea (n = 11, 27.5%), nausea and vomiting (n = 3, 7.5%), gastrointestinal perforation (n = 2, 5%), and thromboembolism (n = 2, 5%). CONCLUSION: Bevacizumab plus irinotecan-based combination chemotherapy is an active and safe treatment option in patients failing oxaliplatin-based therapy.

RESUMO

BACKGROUND: We retrospectively evaluated the activity and toxicity of uracil/tegafur (UFT) plus oral folinic acid in combination with vinorelbine (alternating intravenous (IV) on day 1 and oral on day 8) in patients with metastatic breast cancer. PATIENTS AND METHODS: Treatment consisted of IV vinorelbine 25 mg/m(2) on day 1 and 60 mg/m(2) orally on day 8, and oral UFT 300 mg/m(2) plus leucovorin 60 mg/m(2) on days 1-14 with 21 days interval. All patients were refractory to anthracyclines and taxanes. RESULTS: Partial response (PR) was observed in 3 (9.7%) and stable disease (SD) was observed in 13 (41.9%) patients. Total clinical benefit (PR + SD) of the combination was 51.6%. The median response duration was 3 (range 1-11.8) months. Median overall survival was 9.8 months (95% confidence interval (CI): 7.5-12.1), and median time to progression was 3.4 months (95% CI: 2.3-4.5). The most common toxicities were hematologic, including 4 (12.9%) cases of grade 3 neutropenia and 4 (12.9%) cases of grade 4 neutropenia. Grade 3 diarrhea was reported in 2 (3.2%) patients. 3 (9.7%) patients had hand-foot syndrome. Febrile neutropenia was observed in 1 patient. CONCLUSIONS: Although the combination is safe and convenient in clinical practice, it has only moderate activity in metastatic breast cancer patients.

RESUMO

PURPOSE: To evaluate the serum levels of G-CSF in patients with hepatocellular carcinoma and to compare with values in healthy individuals. PATIENTS AND METHODS: Thirty-three patients with hepatocellular carcinoma and 30 controls were included in the study. Histological confirmation of hepatocellular carcinoma (HCC) was performed by core needle biopsy and patients with cirrhosis were classified according to the Child-Pugh score. The serum G-CSF levels of individuals in both groups were calculated as pg/ml and compared for Child-Pugh Class A, B and C patients with HCC. RESULTS: Median ages of patients with HCC and control group individuals were 58 (range:47-78) and 56 (range 45-70), respectively. Sex distributions were approximately equal. The mean serum level of G-CSF in patients with HCC was 199.4-/+112.2, as compared to 24.0-/+8.8 in the controls (p <0.001). In addition, on subgroup analysis, the serum levels of G-CSF were increased with Child-Pugh Class A, B and C, although without statistical significance (p= 0.253). CONCLUSION: Increased levels of G-CSF are observed in patients with HCC. Further investigations are necessary to clarify the mechanism of G-CSF production and its effects on outcomes.

RESUMO

Treatment of malignant gliomas has changed substantially over the last few years. An oral alkylating agent, temozolomide, has become the standard agent for glioma management. Although it is generally well tolerated, it can cause lymphopenia and may lead to opportunistic infections. We report on a patient with malignant glioma who developed opportunistic cytomegalovirus (CMV) pneumonia following the termination of temozolomide therapy. The patient was admitted with acute dyspnea, fever and hypoxia, and she was diagnosed with CMV pneumonitis using a PCR-based CMV-DNA analysis. After treatment with ganciclovir, she recovered dramatically. To our knowledge, although there have been reported cases of Pneumocystis carinii infection associated with temozolomide therapy, there has only been one other case of CMV infection. We also review this report.
