In the present study, we assessed the association between single nucleotide polymorphisms (SNPs) within nucleotide excision repair (NER) pathway genes (xeroderma pigmentosum complementation group C [XPC], xeroderma pigmentosum complementation group G [XPG], and xeroderma pigmentosum complementation group D [XPD]) and the GI cancer risk in the rural population of Maharashtra.Methods: The genotyping of XPC, XPD, and XPG genes was studied by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method using 200 clinically confirmed GI cancer cases and equal number of healthy controls. The association of polymorphisms was confirmed by odds ratio (OR) with 95% confidence interval (CI).Results: The frequency distribution of XPD gene (C22541A) polymorphism showed that variant A/A genotype increased four times (OR = 4.08; 95% CI = 2.14-7.77; P: < 0.0001) and G23591A polymorphism with heterozygous G/A genotype showed significant correlation (OR = 6.90; 95% CI = 4.28-11.11; P < 0.0001) with risk of GI cancer compared to variant A/A genotype (OR = 1.92; 95% CI = 1.00-3.69; P = 0.04). The results of genetic association analysis of XPC at codon 939 of exon 15 and XPG at codon 1104 of exon 15 showed no association with GI cancer risk in the studied population.Conclusion: Our results indicated that XPD Arg156Arg and Asp312Asn polymorphisms were significantly associated with GI cancer risk whereas XPC Lys939Gln and XPG His1104Asp polymorphisms were not statistically significant.","PeriodicalId":13505,"journal":{"name":"Indian journal of cancer","volume":"62 1","pages":"120-127"},"PeriodicalIF":0.9,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144077650","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a result, alloplastic materials and pedicled musculocutaneous flaps are commonly used in mandibular repair. Although numerous alloplastic materials have been employed with this flap, the majority of research has shown that they have a negative effect. The aim of the study was to see how effective silicon spacers are as a replacement for alloplastic materials in mandibular reconstruction.Methods: A prospective study was conducted on patients who had mandibular reconstruction using soft-tissue repair with or without the use of a silicon spacer. The study comprised a total of 82 patients, 40 of whom had a silicon spacer and 42 of whom did not. The Chi-square test was utilized to assess the functional and cosmetic outcomes in both groups by using the EORTC head-and-neck questionnaire-35 analysis.Results: The majority of the patients were in the T3 and T4a stages. The most common sub-site was buccal mucosa. The average silicon spacer retention time was 62 days, with a retention rate of 22.5%. Infection at the local portion, with or without orocutaneous fistula, was a common reason for silicon spacer removal. Only the speech parameter improved in the silicon spacer group, according to the EORTC head-and neck-questionnaire (P = 0.0290). In 16 individuals, radiation therapy was postponed, which was also significant (P = 0.0123).Conclusion: In patients with oral cavity squamous cell carcinoma who underwent mandibular resection, using a silicon spacer in combination with soft-tissue restoration did not improve functional or cosmetic outcomes except for speech. For comprehensive mandibular reconstruction, only a myocutaneous flap is sufficient.","PeriodicalId":13505,"journal":{"name":"Indian journal of cancer","volume":"62 1","pages":"3-10"},"PeriodicalIF":0.9,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144077828","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we report our experience on the survival and prognostic factors of ES.Materials and methods: Seventy-four newly diagnosed patients with ES, less than 14 years of age, registered in Pediatric Oncology Department of our center, over a period of 5 years, from July 1, 2010 to June 30, 2015, were included.Results: Mean age at presentation was 8.93 years. Primary osseous sites were the extremity (n = 30), pelvis (n = 10), chest wall (n = 9), spine (n = 7), and skull (n = 5), and the extraosseous primary site was involved in 17.6% (n = 13). Metastatic disease was present in 17 patients (23%). Also, 52 patients received three-weekly vincristine/doxorubicin/cyclophosphamide (VDC)/ifosfamide/etoposide (IE) and 21 patients received only VDC. There was no treatment-related mortality. Local control modalities were surgery alone (n = 12), definitive RT (n = 33), surgery and RT (n = 20), palliative RT (n = 4), or none (n = 4). At a median duration of follow-up of 64 months, the 5-year event-free survival (EFS) for the entire cohort was 50.4% (60.6% for localized and 17.6% for metastatic) and the 5-year overall survival (OS) was 54.6% (64.2% for localized and 23.5% for metastatic). Among the prognostic factors analyzed (age, gender, lactate dehydrogenase [LDH] levels, site, and metastases), presence of metastases was the only factor significantly associated with poorer EFS and OS.Conclusion: Localized ES has a favorable outcome even in resource-limited settings, and treatment intensification by interval-compressed chemotherapy may improve the outcomes further. Presence of metastasis at presentation confers a poor outcome.","PeriodicalId":13505,"journal":{"name":"Indian journal of cancer","volume":"62 1","pages":"57-63"},"PeriodicalIF":0.9,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144077989","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
