Background: DNA repair is one of the crucial defense mechanism against mutagenic exposure. Inherited SNPs of DNA repair genes may contribute to variation in DNA repair capacity and susceptibility to cancer. Due to the presence of these variants, inter-individual and ethnic differences in DNA repair capacity have been established in various populations. India harbors enormous genetic and cultural diversity. Materials and Methods: In the present study we aimed to determine the genotypes and allele frequencies of XRCC1 Arg399Gln (rs25487), XRCC3 Thr241Met (rs861539), XPD Lys751Gln (rs13181), and OGG1 Ser326Cys (rs1052133) gene polymorphisms in 186 healthy individuals residing in the Hyderabad region of India and to compare them with HapMap and other populations. Results and Conclusions: The genotype and allele frequency distribution at the four DNA repair gene loci among Hyderabad population of India revealed a characteristic pattern. Comparison of these gene polymorphisms with other populations revealed a distinctiveness of Hyderabad population from the Deccan region of India. To the best of our knowledge, this is the first report of such DNA repair gene polymorphisms in the Deccan Indian population.

Background: Matrix metalloproteinase-2 (MMP-2) is an enzyme with proteolytic activity against matrix proteins, particularly basement membrane constituents. A single nucleotide polymorphism (SNP) at -1306, which disrupts a Sp1-type promoter site (CCACC box), results in strikingly lower promoter activity with the T allele. In the present study, we investigated whether this MMP-2 genetic polymorphism might be associated with susceptibility to colorectal cancer (CRC) in the Saudi population. We also analyzed MMP-2 gene expression level sin CRC patients and 4 different cancer cell lines. Materials and Methods: TaqMan allele discrimination assays and DNA sequencing techniques were used to investigate the $C^{-1306}T$ SNP in the MMP-2 gene of Saudi colorectal cancer patients and controls. The MMP-2 gene expression level was also determined in 12 colon cancer tissue samples collected from unrelated patients and histologically normal tissues distant from tumor margins. Results and Conclusions: The MMP-2 $C^{-1306}T$ SNP in the promoter region was associated with CRC in our Saudi population and the MMP-2 gene expression level was found to be 10 times higher in CRC patients. The MMP-2 $C^{-1306}T$ SNP is significantly associated with CRC in the Saudi population and this finding suggested that MMP-2 variants might help predict CRC progression risk among Saudis. We propose that analysis of this gene polymorphism could assist in identification of patient subgroups at risk of a poor disease outcome.

Background: Genetic aberrations of DNA repair enzymes are known to be common events associated with different cancer entities. The aim of the present study was to analyze genetic associations of rs1805404 (Asp81Asp) and rs1805414 (Ala284Ala) in the PARP1 gene with the risk of breast cancer in Saudi Arabia. Materials and Methods: These two SNP's were analyzed in a primary study group of breast cancer patients and healthy control subjects. Genotypes were determined by TaqMan SNP testing and analyzed using Chi-square or t test and logistic regression analysis with SPSS16.0 software. Results and Conclusions: Results showed that rs1805414 was associated with a significantly increased susceptibility to breast cancer, significant risk being observed for the TC, CC and TC+CC genotypes. In conclusion PARP1 rs1805414 SNP polymorphisms may be involved in the etiology of breast cancer in the Saudi population. In contrast, PARP1 rs1805404 did not show any significant association in overall in breast cancer samples when compared to healthy controls. Confirmation of our findings in larger populations of different ethnicities may provide evidence for a role of the PARP1 gene in breast carcinoma developnment.

Background: Locally advanced head and neck cancer is generally incurable and has a short survival rate. This study aimed to evaluate symptom relief, disease response, and acute toxicity after palliative hypo-fractionated radiotherapy and long-term survival in affected patients. Materials and Methods: Between January 2011 to December 2011, 80 patients who were histopathologically diagnosed as having stage III or stage IV head and neck squamous cell carcinoma based on Eastern Cooperative Oncology Group (ECOG) performance status 1-3, were offered palliative radiotherapy (20 Gy/5Fr/5 Days). Later these patients were evaluated on 30th day after completion of treatment for disease response based on World Health Organisation (WHO) criteria and palliation of symptoms using symptomatic response grading and acute toxicities by the Radiation Therapy Oncology Group (RTOG). Many patients were given post radiation therapy (RT) palliative chemotherapy for appropriate palliative care and a few patients were selected for further curative RT. The overall survival was also evaluated among this group of patients with last follow up date of 1st May, 2014. Results: The most common presenting complaint was pain followed by dysphagia. Most patients (60-70%) had appreciable relief in their presenting symptoms. A good response was observed in the majority following palliative RT; a few patients had progressive disease and some had stable and regressed disease. None of the patients experienced radiation toxicity that required hospital admission. Almost all showed grade one and two acute skin and mucosal toxicity one month after completion of treatment. The mean survival days for patients given only hypofractionated palliative RT was 307 days, those with post palliative RT and palliative chemotherapy was 390 days and patients who went on to receive further palliative RT and curative RT dose had significantly overall survival of 582 days. Conclusions: Advanced head and neck cancer should be identified for suitable palliative hypofractionated radiotherapy to achieve acceptable symptom relief in a great proportion of patients and should be followed by palliative chemotherapy or curative RT in suitable cases for long-term symptom-free survival.

Background: Psoriasis, a common cutaneous disorder characterized by inflammation and abnormal epidermal proliferation with a prevalence of 2-3% in the general population, may be linked to certain types of cancer. Several studies have reported an association between interleukin 10 (IL-10) variant polymorphisms and inflammatory diseases such as psoriasis vulgaris although the results vary according to the population studied. No studies have been performed in the Saudi population. The present study concerned novel variants and other genetic polymorphisms of the promoter and exonic regions of the IL10 gene in patients with moderate to severe psoriasis and potential differences in genotype compared to a group of healthy volunteers. Materials and Methods: Patients with moderate to severe psoriasis and healthy controls with no personal or family history of psoriasis were selected from the central region of Saudi Arabia. Polymorphisms of the IL 10 gene of both groups were genotyped. Results: We observed two novel variants in 5'UTR region of the promoter precursor with higher prevalence of the genotype with both wild-type alleles in patients compared to the healthy control group. The differences at positions -377 and -150 were significantly associated with disease, both the variants conferred strong protection against psoriasis in Saudi patients. Conclusions: This observation provides further support for the importance of the part that IL10 plays in the pathophysiology of this disease. Confirmation of our findings in larger populations of different ethnicities would provide evidence for the role of IL-10 in psoriasis.

Background: X-ray repair cross-complementing group 1 (XRCC1) plays a key role in the base excision repair pathway, as a scaffold protein that brings together proteins of the DNA repair complex. XRCC1 is reported to be a candidate influence on cancer risk. The aim of our present study was to assess the association of rs1799782 (Arg194Trp) and rs25487 (Arg399Gln) XRCC1 gene polymorphisms with breast cancer in the Saudi population. Materials and Methods: The two SNP's were analyzed in breast cancer patients and healthy control subjects. Genotypes were determined by TaqMan SNP genotype analysis technique and data were analyzed using Chi-square or t test and logistic regression analysis by SPSS16.0 software. Results and Conclusions: Results showed that rs1799782 significantly increased susceptibility to breast cancer with Arg/Trp, Arg/Trp+Trp/Trp genotypes and at Trp allele overall study. It also increased risk of breast cancer in older age patients (above 48) and with the ER positive category. XRCC1rs25487 (Arg399Gln) did not showed any significant association. In conclusion the XRCC1rs1799782 polymorphism may be involved in the etiology of breast cancer in the Saudi population. Confirmation of our findings in larger populations of different ethnicities is warranted.

Background: The Saudi population has experienced a sharp increase in colorectal and gastric cancer incidences within the last few years. The relationship between gene polymorphisms of xenobiotic metabolizing enzymes and colorectal cancer (CRC) incidence has not previously investigated among the Saudi population. The aim of the present study was to investigate contributions of CYP1A1, CYP2E1, and GSTM1 gene polymorphisms. Materials and Methods: Blood samples were collected from CRC patients and healthy controls and genotypes were determined by polymerase chain reaction restriction fragment length polymorphism and sequencing. Results and Conclusions: $CYP2E1^*6$ was not significantly associated with CRC development (odd ratio=1.29; confidence interval 0.68-2.45). A remarkable and statistically significant association was observed among patients with $CYP1Awt/^*2A$ (odd ratio=3.65; 95% confidence interval 1.39-9.57). The $GSTM1^*0/^*0$ genotype was found in 2% of CRC patients under investigation. The levels of CYP1A1, CYP2E1 and GSTM1 mRNA gene expression were found to be 4, 4.2 and 4.8 fold, respectively, by quantitative real time PCR. The results of the present case-control study show that the studied Saudi population resembles Caucasians with respect to the considered polymorphisms. Investigation of genetic risk factors and susceptibility gene polymorphisms in our Saudi population should be helpful for better understanding of CRC etiology.

Background: The combination of the adductor canal block (ACB) and the infiltration of anesthetic solution into the interspace between the popliteal artery and capsule of the knee (iPACK) has become increasingly used to augment rapid recovery protocols in total knee arthroplasty (TKA). However, its efficacy in comparison with periarticular anesthetic injection (PAI) alone has yet to be evaluated. Hence, we conducted a retrospective study to compare PAI and ACB + iPACK for controlling pain after TKA. Methods: Propensity scores, incorporating American Society of Anesthesiologists scores, body mass index, age, and sex, were used to match the ACB + iPACK group with the PAI group. All patients received the identical surgical technique and postoperative care. Outcome measures were visual analog scale (VAS) for pain, morphine consumption, knee flexion angle, straight leg raising (SLR), postoperative nausea vomiting (PONV), and length of stay (LOS) after the surgery. Results: After matching by propensity score, there were 49 patients with comparable demographic data in each group. The VAS and morphine requirements of the PAI and ACB + iPACK groups were not different during the first 48 hours after TKA. At 72 hours postoperatively, the VAS of the ACB + iPACK was 0.97 higher than that of the PAI group (p = 0.020). Knee flexion angle, SLR, PONV, and LOS were not significantly different between groups. No procedure-related complications were identified in either group. Conclusions: The anesthesiologist-administered ACB + iPACK was as effective as surgeon-administered PAI in controlling pain in the first 48 hours after TKA. However, the ACB + iPACK group had higher intensity of pain than did the PAI group at 72 hours after TKA.
