Abstract

Introduction: Typhlitis is a complication in GI tract specially in ileum and cecum due to sever prolonged neutropenia. The syndrome usually occurs in patients with leukaemia who take aggressive chemotherapy or in solid tumor treated with taxane base regimen. The syndrome is accompanied with neutropenia, fever, generalized abdominal pain specially in right lower quadrant and probably a mass in this area. Case: The patient is a 44 year old man which was presented with enlargement of right testes since two months ago. In sonographic evaluation of testes a mass was defined and surgery was done for him, which pathologic result was seminoma. Staging workup was done and in CT Scan a lymph node with size of 35 mm was detected in paracaval area . According to this result the patient received chemotherapy with Cisplatin and Etoposide. One day after completion of chemotherapy he developed abdominal pain , fever and bloody diarrhea and referred to hospital and admitted with diagnosis of typhlitis. Conclusion: Typhlitis is not restricted to a complication of leukaemia treatment or taxane base chemotherapy and other cytotoxic drugs can induce this problem. On the other hand, neutropenia and typhlitis can occur immediately after chemotherapy in sensitive patient and so the time of nadir value of white blood cell is too short.

Abstract

Background: Breast Cancer is the most common malignancy and is the second largest cause of death among 35-55 years old women. The aim of this study is explore and to describe women's experiences with breast cancer for achieving a deeper comprehension of their individual experiences. Methods and Materials: This is a qualitative study with a phenomenological approach. Sampling method was purposive and continued till data saturation. Twenty two participants (patients,families and treatment team) attended in the study.Data were collected by using in-depth interviewing and were analyzed by “Parse”method. We tried to analyze qualitative data based on valid criteria. Results: The findings of this research were summarized into four core concepts:delay in diagnosis and treatment, treatment rejection, drowning in suffering (reaction to disease,facing with outcome of treatment,exposure to treatment system, ineffective care and disturbance in daily life of the family) and moving toward normal life. Conclusion: Knowledge of treatment team from the expriences of women suffering from breast cancer helps them to play a better role in their treatment. It seems, this is essential for make a shift from terminal treatment to early diagnosis. Also it emphasise to use of source for support of patients.

Abstract

Background: One of the side effects of chemotherapy agents is gonadal suppression leading to infertility. The present study examined the feasibility of using a gonadotropin releasing hormone agonist (GnRH-A) in the prevention of busulfan induced azoospermia in prepubertal mice.

Materials and Methods: In this case and control research, Leuprolide (3.8 mg/kg) was given to prepubertal male mice 2 weeks after or prior to busulfan (40 mg/kg) administration. The animals received one or two doses of leuprolide after busulfan administration with 4 weeks apart. Six weeks after the last leuprolide treatment, the sperm parameters were analyzed icluded sperm count and motility according to the World Health Organization criteria.

Results: At the time of scarifies, testicular weight were increased in animals receiving leuprolide. In animals receiving leuprolide pretreatment, the percentage of progressive and immotile sperm was significantly (p&le0.05) increased and decreased respectively. But the percentage of non progressive sperm did not change. The sperm motility in busulfan treated animals with post treatment didn't change. The sperm count also increased in pretreatment animals but it was not significant (p&ge0.05).

Conclusion: The present study demonstrates that leuprolide pretreatment resulted in improvement in sperm motility in prepubertal male mice.

Abstract

Background: A small percent of patients with colorectal cancer (CRC) respond to 5-Fluorouracil (5-FU), as a first line of chemotherapy. In this study in, in order to design a new chemotherapy protocol, the effect of 5-FU and acriflavine (ACF) cotreatment on mortality rate of CRC cell lines was investigated.

Materials and Methods: Cytotoxicity of 5-FU and ACF against CRC cell lines (LS174T, SW480 and HCT116) was detected using MTT assay. Cells were treated with different concentrations of 5-FU (0.5-64 µM) or ACF (0.07-5 µM) for 72 hours and then cell viability and drugs IC50 was calculated. To assess the effect of ACF on anticancer activity of 5-FU, cells were cotreated with different concentrations of 5-FU and IC30 concentration of ACF.

Results: ACF and 5-FU suppress the viability of CRC cell lines in dose-dependent manner. 5-FU and ACF have most cytotoxic effect on LS174T and the lowest cytotoxic effect on SW480 cells. Cotreatment of ACF with 5-FU could not significantly change the sensitivity of cells against 5-FU (p>0.05).

Conclusion: In this study, the fatal and cytotoxic effect of ACF on three CRC cell lines was shown. However, cotreatment of ACF with 5-FU could not improve the anticancer activity of 5-FU.
