Loss of appetite is an important factor in the quality of life for advanced cancer patients. Megestrol acetate is used to stimulate appetite, but it can cause suppression of the pituitary adrenal axis due to the affinity of the glucocorticoid receptor. Adrenal insufficiency is a life threatening disorder if left, untreated, but the initial clinical symptoms of the patients are vague. Awareness of the glucocorticoid-like activity of megestrol acetate and its side effects are important for the diagnosis of adrenal insufficiency. We present a case of secondary adrenal insufficiency associated with megestrol acetate in a patient with lung cancer.

Marine sponges are known to produce a number of cytotoxic secondary metabolites. In the course of searching for cytotoxic metabolites from marine organisms, we have evaluated cytotoxic activities of six marine secondary metabolites isolated from various sponges. The cytotoxic compounds 1-6 were isolated by the application of various chromatographic methods, including column chromatography and HPLC. The molecular structures were mostly determined using mass spectrometry (MS) and Nuclear Magnetic Resonance (NMR) Spectroscopy. Furanosestererpenes (compounds 1-3) from Psammocinia sp., cyclitol derivatives (compounds 4 and 5) from Sarcotragus sp., and bromotyrosine-type compound (6) from an association of two sponges Jaspis wondoensis and Poecillastra wondoensis were evaluated for their cytotoxic activity against three cancer cell lines; Hep G2, HeLa, and MCF-7. All tested compounds exhibited cyctoxicity at concentrations ranging from $5\;\mug/mL\;to\;25\;\mug/mL.$ Particularly, among the tested compounds, compound 6 showed the highest potency displaying at least $80\%$ of cytotoxicity at $5\;\mug/mL$ level against all three cancer cell lines.

The laryngeal cancer is a cancer of secondary sex organ, such as malignant tumors of the mammary gland, endometrium, and prostate. The clinical characteristics of the female laryngeal cancers are considered somewhat to be different from that of male. As cancer of the larynx is principally a disease of men, many investigations have showed the characteristics of the male laryngeal cancers. For understanding the clinical characteristics of the female laryngeal cancers, we analyzed 21 cases of laryngeal cancer in women, diagnosed and treated in our institute during the last 10 years. The results were, 1) In female subjects, supraglottis was most common subsite of laryngeal cancer(85.7%). 2) On histopathologic grade, the moderately differentiated squamous cell carcinoma was the most common (80.9%). 3) The positive neck nodes were 19 %, considered to be lower than that of total laryngeal cancer. 4) The treatment results, the 2 year disease free rate and 5 year survival rate were 88.9%, 83.3%, respectively. These results suggest, therefore, female laryngeal cancers are more likely to be supraglottic cancer than glottic cancer. In spite of high incidence of supraglottic cancer, the nodal metastases are rare, the prognosis appeared to be good.

Background: Cancer is a major public health problem in many parts of the world. Gastrointestinal (GI) cancers are responsible for 20% of all cancer-related deaths. In Turkey, stomach cancers account for 8.9%, colon cancer for 6.9%, and pancreatic cancer for 5.9%. This study examined the anxiety-depression levels and the quality of life of patients with GI cancer. Materials and Methods: This descriptive study was carried out on 335 adult patients who had gastrointestinal cancer and who were hospitalized in medical oncology clinics. Data were collected by using hospital anxiety and depression scale, EORTC QLQ C-30 and a patient information form. Results: Patients who were male and secondary school graduates/graduates/postgraduates experienced more functional difficulties. Patients with poor economic status experienced more symptoms. Patient general wellbeing decreased with increase disease duration. The level of functional difficulties decreased with an increasing number of hospital stays. Anxiety scores increased with decreasing age. Both anxiety and depression scores increased with increasing disease duration. Patients who were female, single/widowed/divorced, and literate/elementary school graduates had higher anxiety and depression scores. Life quality decreased with increasing anxiety and depression. Conclusions: Patients should be supported to prevent anxiety and depression, and should be followed up with this in mind.

Background: Breast cancer is the most common cancer among women in Malaysia, about one in 19 women being at risk. This study aimed to investigate knowledge and practice of breast self-examination (BSE), as well as knowledge of risk factors for breast cancer amongst female adolescents in Malaysia. Subsequently, relationships between demographic characteristics and knowledge level of BSE, risk factors for breast cancer and BSE practice were assessed. Materials and Methods: A descriptive, cross sectional survey was conducted using a sample of 500 Malaysian adolescents from the age of 15 to 19 years. A self-administered questionnaire was used to gather socio-demographic characteristics, knowledge of BSE, knowledge of risk factors for breast cancer and BSE practices. Results: The findings of this study indicated that female adolescents in Malaysia demonstrated an inadequate knowledge level of BSE and risk factors for breast cancer. Only 27.8% of female adolescents performed BSE regularly. BSE practice, knowledge of BSE and knowledge of risk factors for breast cancer showed significant positive relationships. Conclusions: The study highlighted the importance of planning and implementing breast health education programs for female students in secondary schools in Malaysia. It will also provide the health care providers an avenue to stress on the importance of imparting breast health education to adolescents.

Self-care to prevent cancer and self-management to cope with the disease are two discrete effective mechanisms for improving of control and management of neoplasia. Both them have certain strategies and practices. Often the two are used interchangeably despite their different approaches. Strategies of self-care usually refer to prevention at different levels include primary, secondary and tertiary. In contrast, strategies of self-management are related to management and alleviation of unpleasant cancer-related symptoms and treatment-related side effects for improving the quality of life of cancer survivors. Successful promoting of self-care and self-management strategies need people and survivor empowerment. Within this context, innovative approaches open a new window. In this paper after a brief review of related strategies and practices, we provide an explanation of how cancer portals may play an important role in the empowerment process and what are key potentials for implementing of self-care and self-management strategies for cancer.

In Incheon Severance Hospital, a secondary delivery hospital, anesthesiologists have treated cancer pain in the operation room when referred from other department. Intrathecal neurolytic block is a valuable means of producing high quality pain relief in any hospital. It is simple to carry out, requires brief hospitalization, can be used in elderly or severely ill patients, can be repeated with the block wears off and its duration is sufficient for the terminal cancer patients. We reviewed the clinical charateristics of the intrathecal alcohol and phenol-glycerine used in two cases of cancer with pain.

Patients undergoing radiation therapy for head and neck cancer (HNC) experience significant early and long-term side effects. The likelihood and severity of complications depends on a number of factors, including the total dose of radiation delivered, over what time it was delivered and what parts of the head and neck received radiation. Late side effects include: permanent loss of saliva; osteoradionecrosis; radiation recall myositis, pharyngoesophageal stenosis; dental caries; oral cavity necrosis; fibrosis; impaired wound healing; skin changes and skin cancer; lymphedema; hypothyroidism, hyperparathyroidism, lightheadedness, dizziness and headaches; secondary cancer; and eye, ear, neurological and neck structures damage. Patients who undergo radiotherapy for nasopharyngeal carcinoma tend to suffer from chronic sinusitis. These side effects present difficult challenges to the patients and their caregivers and require life-long strategies to alleviate their deleterious effect on basic life functions and on the quality of life. This review presents these side effects and their management.

Nevus sebaceous of Jadassohn is a congenital cutaneous hamartoma with epidermal, sebaceous, follicular, and apocrine structures that usually appears at birth or in early childhood. It has the potential to generate a variety of secondary neoplasms of different lineages, and the risk increases with patient age. Although multiple neoplasms may occasionally arise within the same lesion, the coexistence of more than five secondary tumors is extremely rare. Here we report a case of seven secondary tumors including syringocystadenoma papilliferum, desmoplastic trichilemmoma, sebaceoma, trichoblastoma, pigmented trichoblastoma, sebaceous adenoma, and tumor of follicular infundibulum arising within a nevus sebaceous. The complete diagnosis relies on the histopathological analysis of multipoint biopsies and delicate pathological sections.

Natural products have been used as drugs and cosmetics due to their bioactivity and their biochemical diversity. Natural products usually refer to secondary metabolites produced by various living organisms including marine animals, insects, microbes, amphibians, and plants. These secondary metabolites, which usually have molecular weights less than 2,000 amu, are unnecessary for survival, development, growth, and reproduction but play major roles in plant defense systems against other species. These secondary metabolites such as lignans, flavonoids, monoterpenes, and phenylethanoid glycosides showed various biological activities like anti-oxidant behavior, anti-cancer properties, neuroprotective properties, and so forth. Thus, isolation and elucidation of secondary metabolites from living organisms is of great significance to human life.
