Background: Extracorporeal life support (ECLS) in patients with hematologic malignancies is considered to have a poor prognosis. However, to date, there is only one case series reported in the literature. In this study, we compared the in-hospital survival of ECLS in patients with and without hematologic malignancies. Methods: We reviewed a total of 66 patients who underwent ECLS for treatment of acute respiratory failure from January 2012 to December 2014. Of these patients, 22 (32%) were diagnosed with hematologic malignancies, and 13 (59%) underwent stem cell transplantation before ECLS. Results: The in-hospital survival rate of patients with hematologic malignancies was 5% (1/22), while that of patients without malignancies was 26% (12/46). The number of platelet transfusions was significantly higher in patients with hematologic malignancies ($9.69{\pm}7.55$ vs. $3.12{\pm}3.42units/day$). Multivariate analysis showed that the presence of hematologic malignancies was a significant negative predictor of survival to discharge (odds ratio, 0.07; 95% confidence interval, 0.01-0.79); p=0.031). Conclusion: ECLS in patients with hematologic malignancies had a lower in-hospital survival rate, compared to patients without hematologic malignancies.

Radiation-induced second malignancies (RISM) is one of the important late side effects of radiation therapy and has an impact on optimal treatment decision-making. Many factors contribute to the development of RISM such as age at radiation, dose and volume of irradiated area, type of irradiated organ and tissue, radiation technique and individual and family history of cancer. Exact mechanism of RISM is unknown. But nowadays, it is a growing concern in oncology because of the increased number of cancer survivors and efforts are being made to prevent or decrease the incidence of RISM. The primary search for articles was carried via Google Scholar and PubMed with keywords included 'radiation induced malignancies, second malignancies, and chemotherapy induced malignancies'. Additional papers were found through references from relevant articles. In this review article, we have discussed about the pathogenesis, factors contributing to RISM, screening and prevention strategies of RISM.

Background: This cross-sectional observational study was undertaken to establish clinico-pathological characteristics of patients with gynecological malignancies, focusing mainly on symptoms, histological type and stage of the disease at presentation, in a tertiary care setting in Eastern India. Materials and Methods: In the gynecology out-patient clinic of a tertiary care hospital in Kolkata, India, the patients with suggestive symptoms of gynecological malignancies were screened. Their diagnoses were confirmed by histopathology. One hundred thirteen patients with histopathologically confirmed gynecological malignancies were interviewed. Results: The most frequently reported symptoms by the patients with histopathologically confirmed gynecological malignancies were excessive, offensive with or without blood stained vaginal discharge (69.0%), irregular, heavy or prolonged vaginal bleeding (36.3%) and postmenopausal bleeding (31.9%). The majority of the patients (61.0%) had squamous cell carcinoma on histopathological examination, followed by adenocarcinoma (30.1%). Nearly half of the patients (48.7%) were suffering from the Federation Internationale des Gynaecologistes et Obstetristes (FIGO) stage III, followed by stage II (40.7%) malignancy. Conclusions: This study highlights that most of the patients with gynecological malignancies present late at an appropriate health care facility. Ovarian cancer may often have non-specific or misleading symptomatic presentation, whereas cervical cancer often presents with some specific symptoms. These observations point to the need for increasing awareness about gynecological malignancies in the community and providing easily accessible adequate facilities for early detection and treatment of the disease by optimal use of available resources, i.e. strengthening the primary health care system.

Purpose: The purpose of this study was to describe the experience process of adolescents with hematologic malignancies. The question for the study was "What is the experience of adolescents with hematologic malignancies like?" Methods: The grounded theory methodology was used for this study. The data were collected through in-depth interview from 10 adolescents with hematologic malignancies. Data collection was done from January to June 2007. Theoretical sampling was used until the data reached saturation. Results: As a result of the analysis, "Reconstructing self-image from deviated and suspended life" was identified as the core category. And 11 subcategories were identified and they were integrated to the core category. 'Establishment of expanded and matured self' was identified as the consequence. Conclusion: The results of the study provide a frame for effective individualized nursing intervention strategies in helping adjustment of the adolescents with hematologic malignancies.

Fine needle aspiration cytology (FNAC) is a very useful tool in the preoperative diagnosis of lesions of the salivary gland. Surgical therapy of high-grade malignancies (salivary duct carcinoma, mucoepidermoid carcinoma, squamous cellcarcinoma, carcinoma ex pleomorphic adenoma, small cell carcinoma, and sebaceous carcinoma) is different from that of benign lesions or low-grade malignancies. Therefore, the recognition of high-grade malignancies is important in salivary gland FNAC. Although recognition of high-grade malignancies of the salivary gland by FNAC is not difficult, precise classification of these malignancies is often impossible. Additionally, because of its rarity, FNAC of spindle cells and mesenchymal lesions of the salivary glands is a tool that is not familiar to many cytopathologists. The characteristic cytomorphologic features of these lesions are reviewed here with a discussion of specific diagnostic problems.

Objective: To study the incidence, types and distribution pattern of malignant tumors in renal transplant recipients at a single center in Pakistan. Materials and methods: This retrospective study was conducted at Sindh Institute of Urology and Transplantation (SIUT) and included all transplant patients on regular follow-up from November 1986 to December 2008. The original biopsy reports and case files of all patients who developed posttransplant malignancies were reviewed and relevant demographic, clinical, radiological, and histopathological data were retrieved and analyzed. SPSS version 10.0 was used for statistical analysis. Results: Over 22 years of study period, 1816 renal transplants were carried out at our center. Among these, 44 patients developed malignancies constituting an overall incidence rate of 2.4%. All patients in this study were males with a mean age of $34.9{\pm}9.5$ years (range: 9 to 60 years). The most common type of malignancy was lymphoma (27 patients, 61.4%), followed by Kaposi's sarcoma (11 patients, 25%) and skin malignancies (3 patients, 6.8%). One case each of adenocarcinoma of the gallbladder, acute myeloid leukemia (AML), conjunctival carcinoma-in-situ and seminoma were also diagnosed. Conclusion: Posttransplant malignancies occurring in our renal transplant recipients show different incidence rates and patterns as compared with western studies.

Background: This cross-sectional observational study was undertaken to identify the epidemiological characteristics of patients with gynecological malignancies in India, in relation to gynecological cancer risk. Methods: In the gynecology out-patient clinic of a tertiary care hospital in Kolkata, India, the patients with suggestive symptoms of gynecological malignancies were screened. One hundred thirteen patients with histopathologically confirmed gynecological malignancies were interviewed. Results: More than two-thirds of the cases (69.0%) occurred in the age range of 35-64 years and the same proportion of patients was from rural areas. Almost all the patients were "ever-married" (96.5%). More than half (54.9%) were illiterate/just literate. Nearly two-thirds (64.6%) were parity 3 or higher. Among the 18 patients with history of multiple sexual partners of the husband, 94.4% (17) were suffering from cervical malignancy, along with all the 3 patients with history of STD syndromes (sexually transmitted diseases) of their husbands. No one had given a history of condom use by her husband. Most of the patients (91.1%) used old / reused cloth pieces during menstruation. Conclusions: There is a need to increase awareness among women and the broader community about different epidemiological factors that may be responsible for increased risk of gynecological malignancies.

Purpose: To retrospectively analyze variability and clinical significance of serum ferritin levels in Chinese patients with hematologic malignancies. Materials and Methods: Serum ferritin were measured by radioimmunoassay, using a kit produced by the Beijing Institute of Atomic Energy. Patients with hematologic malignancies, and treated in the Department of Hematology in Nanjing First Hospital and fulfilled study criteria were recruited. Results: Of 473 patients with hematologic malignancies, 262 patients were diagnosed with acute leukemia, 131 with lymphoma and 80 with multiple myeloma. Serum ferritin levels of newly diagnosed and recurrent patients were significantly higher than those entering complete remission stage or in the control group (p<0.001). Conclusions: Serum ferritin lever in patients with hematologic malignancies at early stage and recurrent stage are significantly increased, so that detection and surveillance of changes of serum ferritin could be helpful in assessing conditions and prognosis of this patient cohort.

Context: Interest exits in whether TNF-alpha antagonists increase the risk of breast cancer and total malignancies in patients with rheumatoid arthritis (RA). Objectives: To analyze the risk of malignancies, especially breast cancer, in patients with RA enrolled in randomized control trials (RCTs). Methods: A systematic literature search for RCTs from 1 January 1998 to 1 July 2013 from online databases, such as PubMed, WILEY, EMBASE, ISI web of knowledge and Cochrane Library was conducted. Studies included RCTs that compared the safety of at least one dose of the five TNF-${\alpha}$ antagonists with placebo or methotrexate (MTX) (or TNF-${\alpha}$ antagonists plus MTX vs placebo plus MTX) in RA patients for more than 24 weeks and imported all the references into document management software EndNote${\times}6$. Two independent reviewers selected studies and extracted the data about study design, patients' characteristics and the type, number of all malignancies. Results: 28 RCTs from 34 records with 11,741 patients were analyzed. Of the total, 97 developed at least one malignancy during the double-blind trials, and breast cancer was observed in 17 patients (17.5% of total malignancies). However, there was no statistically significant increased risk observed in either the per protocol (PP) model (OR 0.65, 95%CI [0.22, 1.93]) or the modified intention to treat (mITT) model (OR 0.75, 95%CI [0.25, 2.21]). There were also no significant trend for increased risk of total malignancies on anti-TNF-${\alpha}$ therapy administered at approved doses in either model (OR, 1.06, 95%CI [0.64, 1.75], and OR, 1.30, 95%CI [0.80, 2.14], respectively). As to the two models, modified intention to treat model analysis led to higher estimation than per protocol model analysis. Conclusions: This study did not find a significantly increased risk of breast cancer and total malignancies in adults RA patients treated with TNF-${\alpha}$ antagonists at approved doses. However, it cannot be ignored that more patients developed malignancies with TNF-${\alpha}$ antagonists therapy compared with patients with placebo or MTX, in spite of the lack of statistical significance, so that more strict clinical trials and long-term follow-up are needed, and both mITT and PP analyses should be used in such safety analyses.

The purpose of this review is to assess the surgical outcomes of two different treatment modalities, endoscopic and open resection, for the management of sinonasal malignancies by comparing the effectiveness of these two methods. A wide search was carried out considering various electronic databases for English language articles from 2013 to 2018 using keywords such as sinonasal malignancies, endoscopic surgery, open resection for sinonasal malignancies, and endoscopic versus open surgery. One thousand articles were identified from the literature for screening. After a thorough systematic assessment and based on the selection criteria, 10 articles with 4,642 patients were included in this quantitative analysis. With a total of 4,642 patients, 1,730 patients were operated on using endoscopic resection and 2,912 patients were operated on using open resection. The endoscopic approach was found to have a shorter hospital stay compared to open surgical resection (P<0.05). The rate of positive margins and the recurrence rate for open surgical resection were both smaller compared to those for endoscopic resection (P>0.05), and the endoscopic approach had smaller complication rates and a higher survival rate compared to open resection (P>0.05). Though endoscopic resection and open surgical resection have comparable postoperative benefits, preoperative evaluation of cases presenting with sinonasal malignancies is necessary for determining the right treatment method to obtain the best possible results postoperatively.
