Tumor invasion is a critical first step in the organismic dissemination of cancer cells and the formation of metastasis in distant organs, the most important prognostic factor and the actual cause of death in most of the cancer patients. We report here that the cell surface protein podoplanin (PDPN), a potent inducer of cancer cell invasion, is conspicuously expressed by the invasive front of squamous cell carcinomas (SCC) of the cervix in patients and in the transgenic HPV/E2 mouse model of cervical cancer...

Gastric metastasis by solid tumor cancer is a rare event. Concomitant metastases to other organs are frequent, so that this condition is often associated to a poor prognosis. Upper gastrointestinal bleeding and anemia are the most common presenting symptoms. We present the case of a 81 years old women previously treated for cervix carcinoma showing later a stomach metastasis. The patient is alive and disease free 39 months after salvage gastrectomy. A radical surgery in selected patients could be useful for symptom palliation and prolonged survival...

Chemo-radiation represents an effective therapy for carcinoma of the uterine cervix. The endometrium may however receive a consistent dose of mutagenic radiations and patients may have an increased risk of secondary malignancies. Endometrial mixed malignant mullerian tumor (MMMT) is a rare, highly aggressive disease, and neuroendocrine features are even rarer. A 68 years old woman underwent radio-chemotherapy for a squamous cell carcinoma of the cervix. Follow up was uneventful until, eight years after radio-chemotherapy, imaging exams detected a diffuse enlargement of the uterine body...

Drug delivery systems could be applied to locally treat cervical cancer, thus preventing the drawbacks of conventional therapy. In this study, anti-proliferative and anti-angiogenic effects of digoxin incorporated into poly(ε-caprolactone) implants were evaluated, aiming at the local treatment of cervical cancer. Implants were characterized, and the in vitro release profile of digoxin was demonstrated. Anti-proliferative and anti-angiogenic activities of digoxin were investigated by using chorioallantoic membrane and human cervix carcinoma (HeLa) cells, respectively...

Aberrant DNA methylation is a recognized feature in various types of human cancer, and folate has a vital role in the epigenetics of mammalian cells by supplying methyl groups for DNA methylation reactions. Fragile histidine triad (FHIT) is a tumor suppressor gene that is frequently silenced in cervical cancer (CC) and preneoplastic lesions. Promoter hypermethylation was previously observed in CC, and its epigenetic silencing has been observed at mRNA or protein levels. Changes in folate intake to modulate DNA methylation may be a mechanistic link to cancer, but this remains to be elucidated...

Carcinoma cervix is a common cancer among Indian women. Evidence based management is essential for best practice in treatment of carcinoma cervix for its effective control. The current imaging system like CT, MRI and PET CT scans have contributed in identifying the patients for optimal treatment and delivering treatment accurately. For stages IB2 to IV, concurrent chemoradiation is advocated with improvement in overall survival proven with randomized trials. Brachytherapy is an integral part in the radiation treatment...

BACKGROUND: This is an updated version of the original Cochrane review published in 2014, Issue 4. Cervical intraepithelial neoplasia (CIN) precedes the development of invasive carcinoma of the cervix. Current treatment of CIN is quite effective, but there is morbidity for the patient related to pain, bleeding, infection, cervical stenosis and premature birth in a subsequent pregnancy. Effective treatment with medications, rather than surgery, would be beneficial. OBJECTIVES: To evaluate the effectiveness and safety of non-steroidal anti-inflammatory agents (NSAIDs), including cyclooxygenase-2 (COX-2) inhibitors, to induce regression and prevent the progression of CIN...

Context: Carcinoma cervix is a leading cause of cancer in Indian females where 15%-60% of the cases eventually metastasize. Bone only metastasis is rare, and data on its response and survival with systemic therapy as compared to other visceral metastasis are limited. Settings and Design: The study design was a retrospective analysis. Materials and Methods: We retrospectively analyzed our data between May 2013 and April 2015 to identify the cases of bone only metastasis and visceral metastasis and tried to analyze their outcomes with paclitaxel- and carboplatin-based chemotherapy and bisphosphonates (for bone metastasis only)...

Cervical cancer continues to be a leading cancer among women in many parts of the world. Nation-wide screening with the Pap smear has not been implemented in India due to the lack of adequately trained cytologists. Identification of biomarkers to predict malignant potential of the identified low risk lesions is essential to avoid excessive retesting and follow up. The current study analyzed the expression patterns of DNA replication licensing proteins, proliferation inhibitor protein p16INK4A and tumor suppresser protein p63 in cervical tissues and smears to assess the ability of these proteins to predict progression...

REVIEW
Karuna Garg, Anthony N Karnezis, Joseph T Rabban
The most common hereditary gynaecological tumour syndromes are hereditary breast and ovarian cancer syndrome and Lynch syndrome. However, pathologists also may encounter gynaecological tumours in women with rare hereditary syndromes. Many of these tumours exhibit distinctive gross and microscopic features that are associated with a risk for an inherited gene mutation. The sensitivity and specificity of these tumour pathology features for predicting an inherited mutation vary depending on the syndrome. By recognising these tumour features, pathologists may potentially contribute to the diagnosis of an unsuspected syndrome by recommending referral of the patient for formal risk assessment by genetic counselling...

Thyroid cancer is the most common type of endocrine malignancy and a leading cause of death among endocrine organ-related cancers. Similar to other types of cancers, early diagnosis of thyroid cancer is important to increase the survival and treatment of this disease. Several immunohistochemical markers are used in the differential diagnosis of thyroid papillary carcinoma. Also, increasing evidence indicates that P-element induced wimpy testis like 2 (PIWIL2) is an RNA-binding protein involved in the induction and progression of numerous types of human malignancies such as lung, breast, colon, prostate and cervix cancers...
