The recent investigation on PARK-2, a putative tumor suppressor gene, has found that it has been altered in multiple human malignancies. However, the clinical impact of PARK-2 alteration in uterine cervix carcinoma has not yet been studied. Therefore, we aimed to examine mutations, promoter hypermethylation, and protein expression of PARK-2 among the North Indian patients and their association with clinical parameters to evaluate the implication of PARK-2 in the genesis of cervical cancer. A total of 168 patient samples were processed for mutational analysis by single-strand conformation polymorphism, sequencing, and further in silico analysis of the identified mutations...

The regioselective synthesis of estrogens and their derivatives continues to be of interest. Most reported syntheses require multistep protocols associated with poor overall yield and lack of regioselectivity. New preparative protocols are still desired. Herein, 11 2-alkylated 17β -estradiol analogs were synthesized in a highly regioselective manner. The products were obtained using a convenient, one pot and high-yielding protocol. The anti-proliferative activity of the compounds was tested in human T-cell leukemia (CEM), human cervix carcinoma (HeLa) and human dermal microvascular endothelial (HMEC-1) cells...

Cancer besides being a leading cause of mortality also creates a myriad of morbidities in survivors whether treated or untreated. Among women surviving after gynecological malignancies sexual dysfunction is a morbidity unexplored in Indian context because of cultural barriers. With the increasing proportion of women surviving carcinoma of the cervix, quality of life has become an important clinical issue. Despite the immense distress it causes in patients, sexual dysfunction is neither screened nor treated in Indian scenario...

Adenocarcinoma admixed with neuroendocrine carcinoma of the uterine cervix is a rare malignancy with a poor prognosis, and few reports have described the cytological features of this carcinoma. To characterize the cytological features of this malignancy in cervical smears, we report a case of a 52-year-old Japanese woman with cervical adenocarcinoma admixed with small cell neuroendocrine carcinoma (SCNEC). Cytologically, there were two types of cells with different sizes. The smaller cells formed clusters, which showed a partially Indian file pattern, a high nuclear/cytoplasmic ratio, and hyperchromatic nuclei...

Pelvic exenteration was first described by Alexander Brunschwig in 1948 in New York as a palliative procedure for recurrent carcinoma of the cervix. Because of initially high rates of morbidity and mortality, the practice of this ultraradical operation was largely confined to a small number of American centers for most of the 20 century. The post-World War II era saw advances in anaesthesia, blood transfusion, and intensive care medicine that would facilitate the evolution of more radical and heroic abdominal and pelvic surgery...

Large-cell neuroendocrine carcinoma (LCNEC) is a high-grade neuroendocrine tumor. LCNECs arising from the genital organs are highly malignant and rare, with <20 cases of LCNEC developing from the uterine endometrium reported to date. We herein present the case of a patient with LCNEC of the endometrium. The patient was a 52-year-old woman, who exhibited lower abdominal pain and rapid uterine enlargement during outpatient treatment for uterine myoma. The endometrial biopsy suggested a diagnosis of poorly differentiated carcinoma or carcinosarcoma...

AIM: Glycosylation of proteins is altered in cancer cells and distinctive glycan structures are associated with specific cancers, but little is known about the complete glycan profile of particular tumors. In this study, glycomic analysis of squamous cell carcinoma (SCC) of the uterine cervix was performed to search for useful markers. METHODS: A lectin microarray containing 45 lectins with different binding preferences that covered N- and O-linked glycans was coupled with evanescent field-activated fluorescent detection for glycomic analysis of SCC and normal squamous epithelium (NSE) of the cervix...

Literature published between 1975 and 2015 was systematically reviewed to conduct a case-comparator study of tissue based, immunohistochemical biomarker expression among malignant glandular histotypes of the uterine cervix so as to identify differences that could have diagnostic utility. Of the 902 abstracts, 154 articles had a full review, and 52 were included. Biomarker positivity in cases of adenocarcinoma in situ (AIS) were compared with atypical lobular endocervical glandular hyperplasia and invasive histotypes grouped as mucinous, endometrioid, adenosquamous, serous clear cell, minimal deviation-gastric type, and mesonephric carcinomas (7 AIS case-comparators)...

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...

INTRODUCTION: High Dose Rate (HDR) intracavitary brachytherapy is an integral component in treatment of carcinoma uterine cervix. There is no consensus about optimal fractionation in HDR brachytherapy. AIM: To assess the feasibility, tolerability of HDR intracavitary brachytherapy schedule of 8 Gy per fraction per week for 3 fractions over 6Gy per fraction per week for 4 fractions with or without chemotherapy in the treatment of carcinoma of uterine cervix. MATERIALS AND METHODS: From 2013 to 2014 total 80 patients with carcinoma of the uterine cervix (Stages IIB and IIIB) were treated with External Beam Radiotherapy (EBRT) and High Dose Rate Intracavitary Brachytherapy (HDR- ICBT)...

Stroke is a disabling disease which increases the burden of already suffering cancer patients. Several mechanisms of stroke exist in cancer patients which includes - metastatic or non-metastatic such as coagulation disorders, infections or therapy related. Increased risk of ischaemic stroke has been validated for several cancers. However, there is scarce literature reported in carcinoma cervix patients. Review of literature suggests that stroke occurs more frequently in cancer patients than in the average population...

The purpose of the Papanicolaou (Pap) smear is to detect primary squamous lesions of the uterine cervix. Although most successful at detection of squamous lesions, the Pap may also detect metastatic carcinomas, sarcomas, and melanomas. We report two rare cases of myeloid sarcoma (MS) of the uterine cervix identified on screening Pap smears with concurrent confirmatory cervical biopsies. The purpose of our study is to identify and report cytologic features of MS on Pap smears utilizing a liquid-based ThinPrep method, which has not been previously documented in literature...

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...

Neuroendocrine carcinoma of the cervix is an ultra-rare malignancy with a poor prognosis and limited treatment options. Checkpoint blockade immunotherapy has rapidly developed into an emerging standard of care for several common disease types. Interestingly, in preclinical and retrospective clinical data, radiation therapy has been demonstrated to synergize with checkpoint inhibitors. Here we report a patient with metastatic, chemotherapy-refractory neuroendocrine carcinoma who presented with partial bowel obstruction due to a large tumor burden...

Background: Historically the conventional Pap smear has been an effective screening tool for Carcinoma cervix. However the reporting of benign and malignant endometrial cells on Pap smear has remained controversial. There are very few studies addressing the utility of Pap smears in diagnosing endometrial carcinomas. Objective: To rescreen the Pap smears of patients with endometrial adenocarcinoma for the detection of normal/ atypical endometrial cells and to correlate with clinico-pathological parameters. Methods: The present study was carried out at SDM College of Medical Sciences, Dharwad, Karnataka, India for a period of 7 years...

Cervical cancer usually presents in advanced stages and is treated with chemoradiation. About 15-20 % patients present with local recurrence after chemoradiation. Radical surgical resection is the only treatment modality offering long term survival benefit in recurrent cervical cancer. The most common surgical option for these patients is pelvic exenteration. Radical hysterectomy may be done for patients with a small centrally located recurrence in the cervix with no infiltration of adjacent structures. The aim of this study was to evaluate the morbidity and survival outcome following radical hysterectomy and pelvic exenteration for recurrent cancer cervix...
