background: anxiety is the most prevalent psychological side effect of breast cancer and chemotherapy. this study aimed to determine the effect of slow stroke back massage (ssbm) on the anxiety of old female patients with breast cancer undergoing chemotherapy. methods: in this quasi-experimental study, 80 elderly women with breast cancer undergoing chemotherapy were enrolled by continuous sampl...

results the results showed that the mean scores of nausea in the control group was increased from 2.97 on the first day to 3.26 and in the intervention group was decreased from 3.44 to 1.52 at the end of trial. however there was not any significant difference in the first, second, third and fourth days between two groups. conclusions massage can reduce nausea. however further studies with large...

introduction: pathophysiology of cancer is based on genetic instabilities. this can explain recent important role of genetic studies in such diseases. defects can be large (on molecular scale) at the level of chromosomal or small in nucleotide level, which eventually causes to irreversible change in the cell. conventional technical methods in cancer genetics are generally based on molecular or ...

background cancer diagnosis among children can cause high stress and anxiety in parents, and they may lose their life expectancy. the present study investigated the effectiveness of logo therapy on anxiety and depression among mothers of children with cancer. materials and methods this study was conducted by a semi-pilot method using pre-test and post-test with a control experimental group. the...

receptors and proteins are overexpressed in many human cancer cell membranes rather than normal tissues and are considered as the main molecular targets. specific tumor- targeting molecules which have high affinity for these receptors can be valuable tools as carrier molecules for targeted cancer therapy and imaging. pharmacokinetics and bioavailability of diagnostic and therapeutic agents are ...

background: the fundamental principles of internal targeted alpha therapy for cancer were established many decades ago.the high linear energy transfer (let) of alpha radiation to the targeted cancer cellscauses double strand breaks in dna. at the same time, the short range radiation spares adjacent normal tissues. this targeted approach complements conventional external beam radiotherapy and ch...

background: radiation therapy is among the most conventional cancer therapeutic modalities with effective local tumor control. however, due to the development of radio-resistance, tumor recurrence and metastasis often occur following radiation therapy. in recent years, combination of radiotherapy and gene therapy has been suggested to overcome this problem. the aim of the current study was to e...

the cancer of oral cavity is related to lesions of mucous membrane of tongue and gum that can be treated with radiation therapy. a lateral photon field can be used to treat this kind of tumor, which has a side‑effect on normal tissue in the opposite side of the oral cavity. in this study the dosimetric effect of the various shields in oral cavity is evaluated. in this study, a special phantom s...

introduction: radioiodine therapy is an effective method for treating thyroid cancer carcinoma, but it has some affects on normal tissues, hence dosimetry of vital organs are important to weigh the risks and benefits of this method. the aim of this study is to measure the absorbed doses of important organs by mcnp (monte carlo n particle) simulation and comparing the results of different method...

introduction: there is a limited number of case reports published in the past decade confirming the radio-iodine presence in the tear. these observations as well as reported cases of salivary and lacrimal gland dysfunction after radioiodine therapy stimulated investigators to clarify whether lacrimal gland function can be affected post-radioiodine therapy. hence we planned a historical cohort s...
