OBJECTIVE: Mutation carriers (Mut+) in DNA mismatch repair genes are predisposed to cancer of various organs and to adenomatous polyps; however, they may remain asymptomatic and cancer or polyp-free for several years. We purposed to analyse the clinical follow-up of individuals carrying constitutional mutations in the MLH1, MSH2 or MSH6 genes who were unaffected by benign polyps or malignant tumours at diagnosis. MATERIAL AND METHODS: Mut + subjects (n.81) were members of Lynch syndromes in whom mutations were detected between 1993 and 2015; all were asymptomatic at diagnosis...

INTRODUCTION: Whole body PET CT is an important investigation tool in malignancy patients and helps in ascertaining the metabolic activity and exact stage of the disease. However, like any other investigation, false positive results do exist and certain diseases other than cancer may show increased uptake. Hence, a careful evaluation of PET CT and clinical correlation in malignancy patients is a must to accomplish the suitable treatment. METHODS: In this retrospective observational study, seven cases of cancer with concomitant tuberculosis were included...

AIMS: Radiotherapy plays a fundamental role in the treatment of cancer. Currently, the Brazilian public health system cannot match the national radiotherapy demand and many patients requiring radiotherapy are never exposed to this treatment. This study estimated the number of preventable deaths in the public health system if access to radiotherapy was universal. MATERIALS AND METHODS: Incidence rates for the year 2016 provided by Instituto Nacional de Cancer were used in this analysis...

Bladder dose constraints in case of conformational radiotherapy/intensity-modulated radiotherapy and stereotactic radiotherapy are reported from the literature, in particular from the French radiotherapy society RECORAD recommendations, according to the treated pelvic tumor sites. The dose-volume effect on urinary toxicity is not clearly demonstrated, making difficult to establish absolute dose constraints for the bladder. In case of high-dose prostate cancer radiotherapy, the bladder dose constraints are: V60Gy<50% and maximum dose<80Gy for standard fractionation and V60Gy<5%, V48Gy<25% and V41Gy<50% for moderate hypofractionation (20 fractions of 3Gy)...

The use of three dimensional in vitro systems in cancer research is a promising path for developing effective anticancer therapies. The aim of this study was to engineer a functional 3-Din vitro model of normal and cancerous cervical tissue.Normal epithelial and immortalized cervical epithelial carcinoma cell lines were used to construct 3-D artificial normal cervical and cervical cancerous tissues. De-epidermised dermis (DED) was used as a scaffold for both models. Morphological analyses were conducted by using hematoxylin and eosin staining and characteristics of the models were studied by analyzing the expression of different structural cytokeratins and differential protein marker Mad1 using immunohistochemical technique...

We know that one of the main risk factors for cervical cancer is an infection with high-risk human papillomavirus (HR-HPV). Prostaglandins and their receptors are very important for the tumour growth and tumour-associated angiogenesis. Little is known about the expression of the Prostaglandin E receptor type 3 (EP3) or the Prostaglandin (PG)E₂-EP3 signalling in cervical cancer, so the aim of the study was to analyse the expression of the EP3 receptor in cervical cancer and find prognostic factors in relation to survival; EP3 immunohistological staining of 250 cervical cancer slides was performed and analysed with a semi-quantitative score...

Vaginal carcinoma is a rare condition. In this report, we describe a case of a poorly differentiated aggressive adenocarcinoma in a woman with a three month history of vaginal bleeding and a negative Pap smear done six months prior to her consultation. Specular examination showed a normal cervix, but there was a bleeding ulcer (2 cm in diameter) in the upper third of the vagina. Cytology revealed poorly differentiated atypical cells, and the biopsy established a diagnosis of vaginal adenocarcinoma with little differentiation...

OBJECTIVES: Population-based survival statistics are fundamental to assess the efficacy of services offered to improve cancer patients' prognosis. This study aims to update cancer survival estimates for the Italian population, as well as provide new measures, such as the crude probability of death, which takes into account the possibility of dying from causes other than cancer, and the change in life expectancy after a cancer diagnosis, to properly address various questions. RESULTS: The study includes 1,932,450 cancer cases detected by the Network of Italian Cancer Registries (AIRTUM) from 1994 to 2011 and provides estimates for 38 cancer sites and for allsites cancer...

REVIEW

Cervical cancer is an important public health problem. Pap smear is the leading strategy of screening programs for cervical cancer worldwide. However, delayed diagnosis leads to more aggressive and less effective treatments. Patients with uterine cervix malignancies who are referred for radiotherapy have advanced-stage disease, which results in high rates of locoregional recurrence. The use of radiotherapy as a treatment for cervical cancer causes morphological changes in neoplastic and non-neoplastic epithelial cells, as well as in stromal cells, which make it difficult to diagnose the residual lesion, resulting in a dilemma in cytopathological routine...

The cardinal ligament (CL) is one of the major pelvic ligaments providing structural support to the vagina/cervix/uterus complex. This ligament has been studied mainly with regards to its important function in the treatment of different diseases such as surgical repair for pelvic organ prolapse and radical hysterectomy for cervical cancer. However, the mechanical properties of the CL have not been fully determined, despite the important in vivo supportive role of this ligament within the pelvic floor. To advance our limited knowledge about the elastic and viscoelastic properties of the CL, we conducted three consecutive planar equi-biaxial tests on CL specimens isolated from swine...

Lana de Souza Lawrence
Radiotherapy plays a critical role in the management of cervix carcinoma, in the adjuvant setting for patients with high-risk pathologic features and in the definitive setting for locoregionally advanced disease. External beam radiotherapy fields encompass potential areas of microscopic disease spread in addition to known areas of gross disease. In the presence of gross disease, however, escalation of dose is required that is best accomplished using a brachytherapy boost to spare surrounding normal organs from toxicity...

The aim of this study was to investigate the signal-to-noise ratio (SNR) gain in early-stage cervical cancer at ultrahigh-field MRI (e.g. 7 T) using a combination of multiple external antennas and a single endorectal antenna. In particular, we used an endorectal monopole antenna to increase the SNR in cervical magnetic resonance imaging (MRI). This should allow high-resolution, T2 -weighted imaging and magnetic resonance spectroscopy (MRS) for metabolic staging, which could facilitate the local tumor status assessment...

In this report we describe a young patient diagnosed with bulky FIGO stage IIIb squamous cell cervix carcinoma with severe and irreversible nephropathy after three weekly low-doses of cisplatin. Besides several known risk factors such as hypomagnesemia and hypoalbuminemia, the patient also proved to be homozygously polymorphic for two polymorphisms within the COMT gene (c.615 + 310C>T and c.616-367C>T). As COMT polymorphism has been associated with cisplatin-induced ototoxicity, its effect on nephrotoxicity of cisplatin should be the subject of further investigation...

The phenolic content of the ethanol extract of the stem bark of the Brazilian plant Schinopsis brasiliensis Engl. (Anacardiaceae) has been evaluated together with the antioxidant activity. The good antioxidant activity exhibited in the Trolox Equivalent Antioxidant Capacity (TEAC) assay (TEAC value = 3.04 mg/mL) encouraged us to investigate its constituents. An analytical approach based on LC-ESIMS(n) was applied to rapidly obtain a metabolite profile of the ethanol extract of the stem bark of S. brasiliensis...

Ribonucleotide reductase (RNR) is an enzyme involved in the de novo synthesis of deoxyribonucleotides, which are critical for DNA replication and DNA repair. Triapine is a small-molecule RNR inhibitor. A phase I trial studied the safety of triapine in combination with cisplatin-paclitaxel in patients with advanced stage or metastatic solid tumor cancers in an effort to capitalize on disrupted DNA damage repair. A total of 13 patients with various previously treated cancers were given a 96-h continuous intravenous (i...

Gastric-type adenocarcinoma of the cervix (GAS) is an uncommon and aggressive tumour unrelated to human papillomavirus (HPV) infection with distinctive histological and immunohistochemical characteristics. GAS may be associated with lobular endocervical glandular hyperplasia (LEGH), another unusual lesion. We report a case of a 59-year-old woman with screening cytology 'AGC-Neo' and cervical conisation exhibiting cervical intraepithelial neoplasia grade 1, extensive LEGH and canal sampling with abundant mucinous cells...
