Background: Cancer is a major cause of mortality in developing countries and correct and valid information about the epidemiology of this disease is the first step in the planning of health care in each region. The aim of this study was to determine the relative frequency, mean age and sex ratio of the most 10 common non-skin cancers in the world and Iran, among patients referred to an oncology clinic. Materials and Methods: This descriptive study was conducted in Mashhad, north east of Iran. The data obtained from the records of patients referred to the private oncology center between the years of 1985-2012". According to the latest report of GLOBOCAN study commonest malignancies included were lung, breast, colorectal, prostate, stomach, liver, cervix, esophageal, bladder cancers and Non-Hodgkin lymphoma. Results: A total of 4,606 cases were analyzed. The mean age was $55.5{\pm}13.8years$ (male: $59.5{\pm}13.9$, female: $52.6{\pm}12.9$). Overall, breast cancer (1,264 cases, relative frequency of 27.4%) was the most prevalent cancer; however the mean ages of diagnosis were not significantly different between 5-year time period divisions (p=0.290). The most common cancer in men was esophageal cancer (26.3%).The lowest mean age was related to women diagnosed with breast cancer ($48.5{\pm}11.8$) and men with non-Hodgkins lymphoma ($48.4{\pm}17.8$). There were statistically significant differences between the mean age of men and women with gastric (p=0.003) and esophageal cancers (p<0.001). Male to female sex ratios in our study for bladder, lung and stomach cancers were 6.57, 2.60 and 2.50 respectively. Conclusions: The results showed that breast cancer tends to be found in younger female patients and bladder cancer appears more often in men. Screening in target population in addition to early diagnosis may reduce death and disability.

Purpose: This retrospective study compares higher-dose whole-brain radiotherapy (hdWBRT) with reduced-dose WBRT (rdWBRT) in terms of clinical efficacy and toxicity profile in patients treated for primary central nervous system lymphoma (PCNSL). Materials and Methods: Radiotherapy followed by high-dose methotrexate (HD-MTX)-based chemotherapy was administered to immunocompetent patients with histologically confirmed PCNSL between 2000 and 2016. Response to chemotherapy was taken into account when prescribing the radiation dose to the whole brain and primary tumor bed. The whole brain dose was ≤23.4 Gy for rdWBRT (n = 20) and >23.4 Gy for hdWBRT (n = 68). Patients manifesting cognitive disturbance, memory impairment and dysarthria were considered to have neurotoxicity. A median follow-up was 3.62 years. Results: The 3-year overall survival (OS) and progression-free survival (PFS) were 70.0% and 48.9% with rdWBRT, and 63.2% and 43.2% with hdWBRT. The 3-year OS and PFS among patients with partial response (n = 45) after chemotherapy were 77.8% and 53.3% with rdWBRT, and 58.3% and 45.8% with hdWBRT (p > 0.05). Among patients with complete response achieved during follow-up, the 3-year freedom from neurotoxicity (FFNT) rate was 94.1% with rdWBRT and 62.4% with hdWBRT. Among patients aged ≥60 years, the 3-year FFNT rate was 87.5% with rdWBRT and 39.1% with hdWBRT (p = 0.49). Neurotoxicity was not observed after rdWBRT in patients aged below 60 years. Conclusion: rdWBRT with tumor bed boost combined with upfront HD-MTX is less neurotoxic and results in effective survival as higher-dose radiotherapy even in partial response after chemotherapy.
Purpose: F-18 FDG PET/CT has excellent sensitivity and specificity for staging non-Hodgkin lymphomas, but to the author's knowledge few studies to date have evaluated FDG PET/CT in peripheral T cell lymphoma. We evaluated the usefulness of F-18 FDG PET/CT in staging of patients with peripheral T cell lymphoma, especially indolent cutaneous T cell lymphomas. Materials and Methods: Twenty five patients (M:F=17:8, age $53.7{\pm}14.8$ yrs) with biopsy-proven indolent cutaneous T cell (CL) or noncutaneous T cell lymphomas (NCL) underwent PET/CT scans for staging at baseline. Peak standardized uptake values (p-SUV) of all abnormal foci were measured and compared between cutaneous and noncutaneous lesions. F-18 FDG PET/CT was performed on 6 patients with indolent CL and on 19 patients with NCL. Results: All 6 patients with indolent CL had no significant FDG avidity in the skin despite histologically positive cutaneous lesions. However, FDG avidity appeared in extracutaneous lesions (lymph nodes) in two patients with CL where CT imaging suggested lymphoma involvement (mean p-SUV $4.26{\pm}0.37$ in noncutaneous lesions in CL). In NCL, FDG avidity was demonstrated in all lesions where CT imaging suggested lymphoma involvement (mean p-SUV, $8.52{\pm}5.00$ in noncutaneous lesions in NCL). Conclusion: F-18 FDG PET/CT has the limitation of usefulness for the evaluation of the skin in indolent CL. In contrast, F-18 FDG PET/CT is sensitive in staging evaluation of extracutaneous lesions regardless of CL or NCL.
Objectives: The purpose of this retrospective cohort study was to investigate the relationship between exposure of Korean workers to petrochemicals in the refinery/petrochemical industry and lymphohematopoietic cancers. Methods: The cohort consisted of 8,866 male workers who had worked from the 1960s to 2007 at one refinery and six petrochemical companies located in a refinery/petrochemical complex in Korea that produce benzene or use benzene as a raw material. Standardized mortality ratios (SMRs) and standardized incidence ratios (SIRs) were calculated for 1992-2007 and 1997-2005 based on the death rate and cancer incidence rate of the Korean male population according to job title (production, maintenance, laboratory, and office workers). Results: The overall mortality and most cause-specific mortalities were lower among these workers than those of the general Korean population. Increased SMRs were observed for leukemia (4/1.45; SMR 2.77, 95% CI: 0.75-7.09) and lymphohematopoietic cancers (5/2.51; SMR 2, 95% CI: 0.65-4.66) in production workers, and increased SIRs were also observed in leukemia (3/1.34; SIR 2.24, 95% CI: 0.46-6.54) and lymphohematopoietic cancers (5/3.39; SIR 1.47, 95% CI: 0.48-3.44) in production workers, but the results were not statistically significant. Conclusion: The results showed a potential relationship between leukemia and lymphohematopoietic cancers and exposure to benzene in refinery/petrochemical complex workers. This study yielded limited results due to a short observational period; therefore, a follow-up study must be performed to elucidate the relationship between petrochemical exposure and cancer rates.

Objective: To assess the safety of Liena polypeptide injection (produced by JILIN FSENS PHARMACEUTICAL CO.,LTD) combined with chemotherapy in treating patients with advanced cancers. Method: A consecutive cohort of patients with advanced cancers were treated with Liena polypeptide injection combined with chemotherapy. And chemotherapy for patients with advanced cancers were adopted from regimens suggested by NCCN guideline. Liena polypeptide injection was intravenously injected at a dosage of 2ml plus 100ml normal saline for continuous 7 days during chemotherapy as one course. After at least two courses of treatment, safety and side effects were evaluated. Results: There were 20 female and 14 male patients with advanced cancer recruited into this study, including 10 patients with breast, 8 patients with colorectal, 8 patients with lung, 4 patients with gastric, and 1 patient with esophageal cancer, as well as 1 patient with non-Hodgkin's lymphoma, 1 patient with low pharyngeal and 1 patient with urethral cancer. The median age of patients was 59 (40-82) years. Incidences of Grade 1 to 2 myelosuppression was observed in 5/34 patients, and Grade 1 to 2 elevation of hepatic enzyme was recorded in 3/34 patients. Adverse effects on the gastrointestinal tract were documented in 5/34 patients, and were Grade 1. No Grade 3-4 toxicities were diagnosed. No treatment related death was found. Conclusions: Liena polypeptide injection combined with chemotherapy was safe in treating several sites of tumors, that mainly included lung, colorectal and breast cancer. However, further study should be conducted to clarify the effectiveness of this treatment.
Background: The Ministry of Public Health (MOPH) in Lebanon provides cancer drugs free of charge for uninsured patients who account for more than half the total case-load. Other categories of cancer care are subsidized under more stringent eligibility criteria. MOPH's large database offers an excellent opportunity to analyze the cost of cancer treatment in Lebanon. Materials and Methods: Using utilization and spending data accumulated at MOPH during 2008-2013, the cost to the public budget of cancer drugs was assessed per case and per drug type. Results: The average annual cost of cancer drugs was 6,475$ per patient. Total cancer drug costs were highest for breast cancer, followed by chronic myeloid leukemia (CML), colorectal cancer, lung cancer, and Non-Hodgkin's lymphoma (NHL), which together represented 74% of total MOPH cancer drug expenditure. The annual average cancer drug cost per case was highest for CML ($31,037), followed by NHL ($11,566). Trastuzumab represented 26% and Imatinib 15% of total MOPH cancer drug expenditure over six years. Conclusions: Sustained increase in cancer drug cost threatens the sustainability of MOPH coverage, so crucial for socially vulnerable citizens. To enhance the bargaining position with pharmaceutical firms for drug cost containment in a small market like Lebanon, drug price comparisons with neighboring countries which have already obtained lower prices may succeed in lowering drug costs.

Objectives: The objective of this study was to investigate the presence of oral lesions in human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) patients in a descriptive cross-sectional study, and to establish their presence according to levels of CD4+ cells (including the CD4+/CD8+ cell ratio). Materials and Methods: A total of 75 patients infected with HIV were included. Oral lesions were observed and classified using World Health Organization classification guidelines. Potential correlations between the presence and severity of oral lesions and CD4+ cells, including the CD4+/CD8+ cell ratio, were studied. Results: The most frequent oral lesion detected was oral pseudomembranous candidiasis (80.0%), followed by periodontal disease (40.0%), herpetic lesions (16.0%), hairy leukoplakia (16.0%), gingivitis (20.0%), oral ulceration (12.0%), Kaposi's sarcoma (8.0%), and non-Hodgkin's lymphoma (4.0%). The CD4+ count was <$200cells/mm^3$ in 45 cases (60.0%), between $200-500cells/mm^3$ in 18 cases (24.0%), and >$500cells/mm^3$ in 12 cases (16.0%). The mean CD4+ count was $182.18cells/mm^3$. The mean ratio of CD4+/CD8+ cells was 0.26. All patients showed at least one oral manifestation. Conclusion: There was no correlation between the CD4+/CD8+ cell ratio and the presence of oral lesions. The severity of the lesions was more pronounced when the CD4+ cell count was less than $200cells/mm^3$.
This research objected to the diagnosed patients as acute lymphoblastic leukemia, acute myelogenous leukemia, neuroblastoma, non-Hodgkins lymphoma, Hodgkin's disease, kidney tumor, myelodysplastic syndrom and juvenile chronic leukemia after admission in the 'P' hospital in Pusan from Aug. 1. 1999 to Jan. 31. 2000. The results of this study are summarized as follows. 1. On the specific character between the experimental(exp.) group and the control (con.) group : there were 7 of 4-7 years old patients(the most) in the experimental group(53.8%), 5 of 12 years old or older patients in the control group (38.5%). Patients who experienced operation were 7 in the exp. group(53.8%) and 6 in con. group(46.2%). The largest number of the patients' diagnosis was acute lymphoblastic leukemia by 5 in the exp. group(38.5%) and 4 in the con. group (30.8%). The hardest nausea came on the second day by 5 in the exp. group(38.5%), 9 in the con. group(69.2%). 2. P-score of the nausea vomiting on the number of daily anticancer drug administration : first day, the exp. group got 9.6 and the con. group 17.6(P = 0.03). 2nd day, 10.9 and 19.4(P = 0.00), 3rd day, 10.6 and 18.3(P = 0.00), 4th day 10.0 and 18.0, 5th day 10.9 and 16.8(P = 0.05). The score showed statistically significant difference(P < .05). 3. Oral intake didn't show statistically significant difference between two groups. However the average of Oral intake of the exp. group was continually higher than the con. group except to the first day after administration. In conclusion, nursing intervention and nutrition care are much more needed on the 2-3th day after administration to reduce nausea vomiting, and for remission of nausea and enlarging oral intake it is utilizable to apply the easy, economic Oral Cryotherapy to the young patients who undergo chemotherapy.
Objective: This study aimed to identify the status and risk factors of rituximab infusion-related adverse events (ADE) in rituximab-na$\ddot{i}$ve patients with cancer diseases. Method: A retrospective analysis using electronic medical records review was conducted. Inclusions were patients with a diagnosis of cancer disease with the initiation of rituximab-included treatment who were na$\ddot{i}$ve to rituximab during January 2011 to March 2013 at National Cancer Center (NCC) in Korea. Result: Total 110 patients, 582 cases of rituximab administrations, were reported in the study. About 57.2% of patients were 51-70 years old and evenly distributed between two genders and 72.7% were BMI less than $25kg/m^2$. All of study patients were diagnosed with non-Hodgkin lymphoma. Fifty patients (45.4%) and 54 cases (9.3%) were experienced rituximab infusion-related AEs even with conservative administration protocol at NCC. The most frequently occurring AEs were shivering followed by rash and itching. In single variant analysis, we found that the early stage of NHL, low exposure to rituximab administrations, high white blood cell counts, high lymphocyte counts, high absolute neutrophil count and low lactate dehydrogenase were associated with infusion-related AEs (p<0.05). The early stage of disease, high lymphocyte counts, low exposure to rituximab administrations were also related significantly with AEs in multiple variants analysis (p<0.05). Conclusion: Rituximab infusion-related AEs for patients who were na$\ddot{i}$ve to rituximab were still a concern with conservative administration protocol. The adverse drug reactions were significantly associated with early stage of NHL, higher lymphocyte counts and low exposure to rituximab administrations. The factors need to be considered with close monitoring to prevent rituximab infusion-related AE.
Radiotherapy and chemotherapy can effectively control cancer but can also cause new second cancers to develop as long-term complications especially in childhood cancer. We experienced two patients with second malignant solid neoplasm who had been treated with radiation and chemotherapy for childhood cancers One female patient with rhabdomyosarcoma of the right popliteal fossa was treated with radiotherapy at total dose of 54Gy Three years and seven months later, osteosarcoma developed in the field of radiation therapy The other male patient with non-Hodgkin's lymphoma of the small bowel was treated with radiotherapy and leiomyosarcoma developed in the field of radiotherapy 18 years later. We reviewed the literature of the second malignant neoplasm in children in respect of risk factors. The risk for a second primary cancer following radiotherapy or chemotherapy emphasizes the need for life long follow-up of patients receiving such treatments, particularly patients treated for childhood cancers.
