Abstract:
Oral cancer ranks first among males and is the primary cause of cancer-related deaths in Pakistan. We studied the epidemiology and risk factors associated with this cancer. The main risk factors in the Pakistani population include the usage of chewable and non-chewable tobacco, areca nut, betel leaf, poor dental hygiene practices, oncogenic viral infections, and genetic predispositions. The impact of socioeconomic status and the available health resources on the management of oral cancer is also discussed. It is concluded that being a low-middle economy efforts should be primarily focused on awareness for early screening, diagnosis, and prevention strategies.

Abstract:
The Japanese Lifespan Study (LSS) of the A-Bomb survivors is the principal basis of the current legal radiological framework. Evidence provided for the first time here shows that internal exposure to radiologically significant quantities of Uranium-234 contained in sub-micron particle rainout from the un-fissioned weapon warhead, the Black Rain, is a missing exposure in the LSS analysis. It is argued that this is responsible for a background excess cancer risk in all the LSS dose groups. This, together with epidemiological evidence based on unexposed controls falsifies the LSS cancer vs. dose regression coefficients for internal exposure.

Abstract:
Since the human genome contains about 6% of tumor suppressor genes (TSGs) and the X chromosome alone holds a substantial share (2%), herein, we have discussed exclusively the relative contribution of X-linked human TSGs that appear to be primarily involved in 32 different cancer types. Our analysis showed that, a) the majority of X-linked TSGs are primarily involved in the dysregulation of breast cancer, followed by prostate cancer, b) Despite being escaped from X chromosome inactivation (XCI), a clear pattern of altered promoter methylation linked to the mutational burden was observed among them. c) X-linked TSGs (mainly on the q-arm) maintain spatial and genetic interactions with certain autosomal loci. Corroborating our previous findings that loss/gain of entire sex chromosomes (in XO and XXY syndromes) can profoundly affect the epigenetic status of autosomes we herein suggest that X-linked TSGs alone can also contribute significantly in the dynamics this sex chromosome-autosome crosstalk to restructure the cancer genome.

Abstract:
Surgical removal of the tumor is currently the first-line treatment for lung cancer, but the procedure may accelerate cancer progression through immunosuppression. However, whether CCL2 (C-C motif chemokine ligand 2) enhances cancer progression by affecting regulatory T cells (Tregs) remains unknown. We found that the volume and weight of tumors were larger in the surgical trauma group than in the control group. CCL2 expression and Treg abundance were increased in tumor tissues after surgical trauma, and CCL2 expression was positively associated with Treg abundance. These results demonstrated that surgical trauma contributes to lung cancer progression by increasing CCL2 expression, thus promoting Treg recruitment.

Abstract:
The random allocation of therapies in randomized clinical trials is a powerful tool that removes all confounding biases that can affect treatment assignment. However, confounders influencing mediators of the treatment effect are unaffected by randomization and should be considered during trial design and statistical modeling. Examples of such mediators include biomarkers predictive of response to targeted therapies in oncology. Patient selection for such biomarkers is prudent in clinical trials. Conversely, prognostic information on outcome heterogeneity can be derived from observational datasets that include more representative populations. The fusion of experimental and observational data can then allow patient-specific inferences.

Abstract:
In this retrospective analysis of 36 patients with recurrent ovarian cancer (ROC) treated with platinum pemetrexed doublet ± bevacizumab, the median age was 54.5 years (47–60) and 33 (91.7%) had serous histology. The overall response rate [ORR = complete (CR)+partial (PR) response] was 83.3%. At a median follow-up of 16 months, the median PFS was 13.8 months (95% CI: 10.849–20.580) and median OS 30.6 months, (95% CI: 21.46 months-NR). The incidence of Grade 3/4 anemia, thrombocytopenia, neutropenia and non-hematological toxicity was 19.4%, 3.9%, 16.6%, and 8.3%. Platinum pemetrexed chemotherapy in ROC is safe and effective treatment option.

Abstract:
The aim of this study is to analyze the correlation between clinically significant histologic results and HPV in women with AGC in pap test. Of the 311 women confirmed as AGC, 111 women (35.7%) was identified as positive for HPV. In the AGC analysis, cervical lesions were significantly more common in HPV positive group compared to HPV negative group (61.2% vs. 10.5%, p < 0.001). In contrast, endometrial lesions were not associated with HPV infection (8.1% vs. 4.5%, p = 0.12). The HPV-DNA testing in women with AGC may be a useful tool for predicting clinically significant cervical lesions.

Abstract:
Axillary nodal metastasis is related to poor prognosis in breast cancer (BC). Key candidate genes in BC lymph node metastasis have been identified from Gene Expression Omnibus datasets and explored through functional enrichment database for annotation, visualization and integrated discovery (DAVID) , protein-protein interaction by Search Tool for the Retrieval of Interacting Genes and proteins (STRING), network visualization (Cytoscape), survival analysis (GEPIA, KM Plotter), and target prediction (miRNet). A total of 102 overlapping differentially expressed genes were found. In-silico survival and expression analyses revealed six candidate hub genes, Desmocollin 3 (DSC3), KRT5, KRT6B, KRT17, KRT81, and SERPINB5, to be significantly associated with nodal metastasis and overall survival, and 83 MicroRNA (miRNAs), which may be potential diagnostic markers and therapeutic targets in BC patients.
